Systematic review of individual-level, community-level, and healthcare system-level factors contributing to socioeconomic differences in healthcare utilisation in OECD countries with universal health coverage

Por: Meulman · I. · Uiters · E. · Cloin · M. · Polder · J. · Stadhouders · N.
Objectives

Countries with universal health coverage (UHC) strive for equal access for equal needs without users getting into financial distress. However, differences in healthcare utilisation (HCU) between socioeconomic groups have been reported in countries with UHC. This systematic review provides an overview individual-level, community-level, and system-level factors contributing to socioeconomic status-related differences in HCU (SES differences in HCU).

Design

Systematic review following the Preferred Reporting Items for Systematic review and Meta-Analysis (PRISMA) guidelines. The review protocol was published in advance.

Data sources

Embase, PubMed, Web of Science, Scopus, Econlit, and PsycInfo were searched on 9 March 2021 and 9 November 2022.

Eligibility criteria

Studies that quantified the contribution of one or more factors to SES difference in HCU in OECD countries with UHC.

Data extraction and synthesis

Studies were screened for eligibility by two independent reviewers. Data were extracted using a predeveloped data-extraction form. Risk of bias (ROB) was assessed using a tailored version of Hoy’s ROB-tool. Findings were categorised according to level and a framework describing the pathway of HCU.

Results

Of the 7172 articles screened, 314 were included in the review. 64% of the studies adjusted for differences in health needs between socioeconomic groups. The contribution of sex (53%), age (48%), financial situation (25%), and education (22%) to SES differences in HCU were studied most frequently. For most factors, mixed results were found regarding the direction of the contribution to SES differences in HCU.

Conclusions

SES differences in HCU extensively correlated to factors besides health needs, suggesting that equal access for equal needs is not consistently accomplished. The contribution of factors seemed highly context dependent as no unequivocal patterns were found of how they contributed to SES differences in HCU. Most studies examined the contribution of individual-level factors to SES differences in HCU, leaving the influence of healthcare system-level characteristics relatively unexplored.

Adjuvant Wilms tumour 1-specific dendritic cell immunotherapy complementing conventional therapy for paediatric patients with high-grade glioma and diffuse intrinsic pontine glioma: protocol of a monocentric phase I/II clinical trial in Belgium

Por: Van Genechten · T. · De Laere · M. · Van den Bossche · J. · Stein · B. · De Rycke · k. · Deschepper · C. · Hazes · K. · Peeters · R. · Couttenye · M.-M. · Van De Walle · K. · Roelant · E. · Maes · S. · Vanden Bossche · S. · Dekeyzer · S. · Huizing · M. · Caluwaert · K. · Nijs · G. · Cool
Introduction

Diffuse intrinsic pontine glioma (DIPG) and paediatric high-grade glioma (pHGG) are aggressive glial tumours, for which conventional treatment modalities fall short. Dendritic cell (DC)-based immunotherapy is being investigated as a promising and safe adjuvant therapy. The Wilms’ tumour protein (WT1) is a potent target for this type of antigen-specific immunotherapy and is overexpressed in DIPG and pHGG. Based on this, we designed a non-randomised phase I/II trial, assessing the feasibility and safety of WT1 mRNA-loaded DC (WT1/DC) immunotherapy in combination with conventional treatment in pHGG and DIPG.

Methods and analysis

10 paediatric patients with newly diagnosed or pretreated HGG or DIPG were treated according to the trial protocol. The trial protocol consists of leukapheresis of mononuclear cells, the manufacturing of autologous WT1/DC vaccines and the combination of WT1/DC-vaccine immunotherapy with conventional antiglioma treatment. In newly diagnosed patients, this comprises chemoradiation (oral temozolomide 90 mg/m2 daily+radiotherapy 54 Gy in 1.8 Gy fractions) followed by three induction WT1/DC vaccines (8–10x106 cells/vaccine) given on a weekly basis and a chemoimmunotherapy booster phase consisting of six 28-day cycles of oral temozolomide (150–200 mg/m2 on days 1–5) and a WT1/DC vaccine on day 21. In pretreated patients, the induction and booster phase are combined with best possible antiglioma treatment at hand. Primary objectives are to assess the feasibility of the production of mRNA-electroporated WT1/DC vaccines in this patient population and to assess the safety and feasibility of combining conventional antiglioma treatment with the proposed immunotherapy. Secondary objectives are to investigate in vivo immunogenicity of WT1/DC vaccination and to assess disease-specific and general quality of life.

Ethics and dissemination

The ethics committee of the Antwerp University Hospital and the University of Antwerp granted ethics approval. Results of the clinical trial will be shared through publication in a peer-reviewed journal and presentations at conferences.

Approaches for the treatment of perforated peptic ulcers: a network meta-analysis of randomised controlled trials - study protocol

Por: Wadewitz · E. · Friedrichs · J. · Grilli · M. · Vey · J. · Zimmermann · S. · Kleeff · J. · Ronellenfitsch · U. · Klose · J. · Rebelo · A.
Introduction

Perforated peptic ulcers are a life-threatening complication associated with high morbidity and mortality. Several treatment approaches are available. The aim of this network meta-analysis (NMA) is to compare surgical and alternative approaches for the treatment of perforated peptic ulcers regarding mortality and other patient-relevant outcomes.

Methods and analysis

A systematic literature search of PubMed/MEDLINE, Cochrane Library, Embase, CINAHL, ClinicalTrials.gov trial registry and ICTRP will be conducted with predefined search terms.

To address the question of the most effective treatment approach, an NMA will be performed for each of the outcomes mentioned above. A closed network of interventions is expected. The standardised mean difference with its 95% CI will be used as the effect measure for the continuous outcomes, and the ORs with 95% CI will be calculated for the binary outcomes.

Ethics and dissemination

In accordance with the nature of the data used in this meta-analysis, which involves aggregate information from previously published studies ethical approval is deemed unnecessary. Results will be disseminated directly to decision-makers (eg, surgeons, gastroenterologists) through publication in peer-reviewed journals and presentation at conferences.

Role of motivation and well-being indicators in interventions to improve well-being at work among primary care physicians: a systematic review

Por: Florez · A. · Villar-Hoz · E.
Objective

The well-being of primary care physicians (PCPs) has become an object of concern for governments due to staff shortages and high staff turnover. The objective of this study was to carry out a systematic review of individualised interventions aimed at improving the well-being of PCPs, which allowed us to determine (1) the type of interventions being carried out; (2) the well-being indicators being used and the instruments used to assess them; (3) the theories proposed to support the interventions and the mechanisms of action (MoA) put forward to explain the results obtained and (4) the role that individual motivation plays in the interventions to improve well-being among PCPs.

Design

Systematic review.

Eligibility criteria

Clinical trials on interventions aimed at improving the well-being of PCPs.

Information sources: a search of studies published between 2000 and 2022 was carried out in MEDLINE/PubMed, SCOPUS and Web of Science (WOS).

Results

From the search, 250 articles were retrieved. The two authors each reviewed the articles independently, duplicate articles and those that did not meet the inclusion criteria were discarded. A total of 14 studies that met the criteria were included: 6 randomised clinical trials, 4 controlled clinical trials and 4 unique cohorts, with a before-and-after assessment of the intervention, involving a total of 655 individuals participating in the interventions. A meta-analysis was not possible due to the heterogeneity of the studies.

Conclusions

The information evaluated is insufficient to accurately assess which outcomes are the best indicators of PCPs well-being or what role plays in the individual motivation in the results of the interventions. More studies need to be carried out on the subject to determine the MoA of the different interventions on the results and the motivation of the participating PCPs.

Evaluating the impact of movement tracking feedback on engagement with home exercise programmes of children with cerebral palsy using a new therapy app: a protocol for a mixed-methods single-case experimental design with alternating treatments

Por: Petrevska · M. · Wright · F. V. · Khan · A. · Munce · S. · Fehlings · D. · Biddiss · E.
Introduction

Children with cerebral palsy (CP) are prescribed home exercise programmes (HEPs) to increase the frequency of movement practice, yet adherence to HEPs can be low. This paper outlines the protocol for a single-case experimental design (SCED) with alternating treatments, using a new home therapy exercise application, Bootle Boot Camp (BBCamp), offered with and without movement tracking feedback. This study will explore the impact of feedback on engagement, movement quality, lower limb function and family experiences to help understand how technology-supported HEPs should be translated and the added value, if any, of movement tracking technology.

Methods and analysis

In this explanatory sequential mixed-methods study using a SCED, 16 children with CP (aged 6–12 years, Gross Motor Function Classification System levels I–II) will set lower limb goals and be prescribed an individualised HEP by their physiotherapist to complete using BBCamp on their home television equipped with a three-dimensional camera-computer system. Children will complete four weekly exercise sessions over 6 weeks. Children will be randomised to 1 of 16 alternating treatment schedules where BBCamp will provide or withhold feedback during the first 4 weeks. The version of BBCamp that results in the most therapeutic benefit will be continued for 2 final weeks. Goals will be re-evaluated and families interviewed. The primary outcome is adherence (proportion of prescribed exercise repetitions attempted) as a measure of behavioural engagement. Secondary outcomes are affective and cognitive engagement (smiley face ratings), exercise fidelity, lower limb function, goal achievement and participant experiences. SCED data will be analysed using visual and statistical methods. Quantitative and qualitative data will be integrated using joint displays.

Ethics and dissemination

Ethical approval was obtained from the Research Ethics Boards at Bloorview Research Institute and the University of Toronto. Results will be distributed through peer-reviewed journals and scientific conferences.

Exploration of Latina/Hispanic womens experiences living with non-alcoholic fatty liver disease: a qualitative study with patients in Houston

Por: Heredia · N. I. · Mendoza Duque · E. · Ayieko · S. · Averyt · A. · McNeill · L. H. · Hwang · J. P. · Fernandez · M. E.
Objectives

A deeper understanding of the lived experiences of Hispanic patients with non-alcoholic fatty liver disease (NAFLD) can help guide the development of behavioural programmes that facilitate NAFLD management. This paper explores Hispanic women’s experiences living with NAFLD.

Design, setting, participants

We collected brief sociodemographic questionnaires and conducted in-depth interviews with 12 low-income (all had household income ≤USD$55 000 per year) Hispanic women with NAFLD from the Houston area. Transcripts were audio-recorded and transcribed. We developed a coding scheme and used thematic analysis to identify emergent themes, supported by Atlas.ti.

Results

Participants identified physicians as their main information source on NAFLD but also consulted the internet, family, friends and peers. Many were still left wanting more information. Participants identified family history, sedentary lifestyles, poor diet and comorbid conditions as causes for their NAFLD. Participants also reported emotional distress after diagnosis. Participants experienced both successes and challenges in making lifestyle changes in nutrition and physical activity. Some participants received desired social support in managing NAFLD, although there were conflicting feelings about spousal support.

Conclusion

Multifaceted programming that improves patient–provider communication, conveys accurate information and enhances social support is needed to support Hispanic women in managing NAFLD.

Experiences, prevalence and drivers of disrespect and abuse of adolescents during facility-based childbirth in sub-Saharan Africa: a scoping review protocol

Por: Udho · S. · Clow · S. E.
Introduction

Adolescents are more likely to experience disrespect and abuse (D&A) by skilled health personnel during facility-based childbirth. However, research evidence on the experiences, prevalence and drivers of D&A of adolescents in childbirth is limited. We aim to establish research evidence on the experiences, prevalence and drivers of D&A of adolescents during facility-based childbirth in sub-Saharan Africa and identify gaps in the literature to inform future research.

Methods and analysis

The protocol is designed using Arksey and O’Malley’s methodological framework and will be reported following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews. We will systematically search to retrieve peer-reviewed articles published in English from 2011 to date in PubMed/Medline, EBSCOhost (Africa Wide Information, CINAHL, PsycINFO and SocINDEX), Web of Science (SciELO Citation Index and Web of Science Core Collection) and Scopus. Two independent reviewers will screen the references by titles, abstracts and full texts. Discrepancies in screening results will be resolved through discussions. Key elements of included studies will be charted using a predetermined tool. We will perform numerical analysis and synthesis of narrative accounts of the extent, nature and distribution of review studies.

Ethics and dissemination

No ethical approval is required since the scoping review will use openly available public data and information. Review findings will be disseminated at conferences and published in peer-reviewed journals. No protocol registration is required.

Subphenotypes of self-reported symptoms and outcomes in long COVID: a prospective cohort study with latent class analysis

Por: Kitsios · G. D. · Blacka · S. · Jacobs · J. J. · Mirza · T. · Naqvi · A. · Gentry · H. · Murray · C. · Wang · X. · Golubykh · K. · Qurashi · H. · Dodia · A. · Risbano · M. · Benigno · M. · Emir · B. · Weinstein · E. · Bramson · C. · Jiang · L. · Dai · F. · Szigethy · E. · Mellors · J. W. · Met
Objective

To characterise subphenotypes of self-reported symptoms and outcomes (SRSOs) in postacute sequelae of COVID-19 (PASC).

Design

Prospective, observational cohort study of subjects with PASC.

Setting

Academic tertiary centre from five clinical referral sources.

Participants

Adults with COVID-19 ≥20 days before enrolment and presence of any new self-reported symptoms following COVID-19.

Exposures

We collected data on clinical variables and SRSOs via structured telephone interviews and performed standardised assessments with validated clinical numerical scales to capture psychological symptoms, neurocognitive functioning and cardiopulmonary function. We collected saliva and stool samples for quantification of SARS-CoV-2 RNA via quantitative PCR.

Outcomes measures

Description of PASC SRSOs burden and duration, derivation of distinct PASC subphenotypes via latent class analysis (LCA) and relationship with viral load.

Results

We analysed baseline data for 214 individuals with a study visit at a median of 197.5 days after COVID-19 diagnosis. Participants reported ever having a median of 9/16 symptoms (IQR 6–11) after acute COVID-19, with muscle-aches, dyspnoea and headache being the most common. Fatigue, cognitive impairment and dyspnoea were experienced for a longer time. Participants had a lower burden of active symptoms (median 3 (1–6)) than those ever experienced (p

Conclusions

We identified three distinct PASC subphenotypes. We highlight that although most symptoms progressively resolve, specific PASC subpopulations are impacted by either high burden of constitutional symptoms or persistent olfactory/gustatory dysfunction, requiring prospective identification and targeted preventive or therapeutic interventions.

UK medical students self-reported knowledge and harm assessment of psychedelics and their application in clinical research: a cross-sectional study

Por: Song-Smith · C. · Jacobs · E. · Rucker · J. · Saint · M. · Cooke · J. · Schlosser · M.
Objective

To capture UK medical students’ self-reported knowledge and harm assessment of psychedelics and to explore the factors associated with support for changing the legal status of psychedelics to facilitate further clinical research.

Design

Cross-sectional, anonymous online survey of UK medical students using a non-random sampling method.

Setting

UK medical schools recognised by the General Medical Council.

Participants

132 medical students who had spent an average of 3.8 years (SD=1.4; range: 1–6) in medical school.

Results

Most students (83%) reported that they were aware of psychedelic research and only four participants (3%) said that they were not interested in learning more about this type of research. Although medical students’ harm assessment of psychedelics closely aligned with that of experts, only 17% of students felt well-educated on psychedelic research. Teachings on psychedelics were only rarely encountered in their curriculum (psilocybin: 14.1 (SD=19.9), scale: 0 (never) to 100 (very often)). Time spent at medical schools was not associated with more knowledge about psychedelics (r=0.12, p=0.129). On average, this sample of medical students showed strong support for changing the legal status of psychedelics to facilitate further research into their potential clinical applications (psilocybin: 80.2 (SD=24.8), scale: 0 (strongly oppose) to 100 (strongly support)). Regression modelling indicated that greater knowledge of psychedelics (p

Conclusions

Our findings reveal a significant interest among UK medical students to learn more about psychedelic research and a strong support for further psychedelic research. Future studies are needed to examine how medical education could be refined to adequately prepare medical students for a changing healthcare landscape in which psychedelic-assisted therapy could soon be implemented in clinical practice.

Examining geospatial and temporal distribution of invasive non-typhoidal Salmonella disease occurrence in sub-Saharan Africa: a systematic review and modelling study

Por: Kim · J.-H. · Tack · B. · Fiorino · F. · Pettini · E. · Marchello · C. · Jacobs · J. · Crump · J. · Marks · F. · Vacc-iNTS Consortium
Background

Invasive non-typhoidal Salmonella (iNTS) disease is a significant health concern in sub-Saharan Africa. While our knowledge of a larger-scale variation is growing, understanding of the subnational variation in iNTS disease occurrence is lacking, yet crucial for targeted intervention.

Method

We performed a systematic review of reported occurrences of iNTS disease in sub-Saharan Africa, consulting literature from PubMed, Embase and Web of Science published since 2000. Eligibility for inclusion was not limited by study type but required that studies reported original data on human iNTS diseases based on the culture of a normally sterile site, specifying subnational locations and the year, and were available as full-text articles. We excluded studies that diagnosed iNTS disease based on clinical indications, cultures from non-sterile sites or serological testing. We estimated the probability of occurrence of iNTS disease for sub-Saharan Africa on 20 km x 20 km grids by exploring the association with geospatial covariates such as malaria, HIV, childhood growth failure, access to improved water, and sanitation using a boosted regression tree.

Results

We identified 130 unique references reporting human iNTS disease in 21 countries published from 2000 through 2020. The estimated probability of iNTS occurrence grids showed significant spatial heterogeneity at all levels (20 km x 20 km grids, subnational, country and subregional levels) and temporal heterogeneity by year. For 2020, the probability of occurrence was higher in Middle Africa (0.34, 95% CI: 0.25 to 0.46), followed by Western Africa (0.33, 95% CI: 0.23 to 0.44), Eastern Africa (0.24, 95% CI: 0.17 to 0.33) and Southern Africa (0.08, 95% CI: 0.03 to 0.11). Temporal heterogeneity indicated that the probability of occurrence increased between 2000 and 2020 in countries such as the Republic of the Congo (0.05 to 0.59) and Democratic Republic of the Congo (0.10 to 0.48) whereas it decreased in countries such as Uganda (0.65 to 0.23) or Zimbabwe (0.61 to 0.37).

Conclusion

The iNTS disease occurrence varied greatly across sub-Saharan Africa, with certain regions being disproportionately affected. Exploring regions at high risk for iNTS disease, despite the limitations in our data, may inform focused resource allocation. This targeted approach may enhance efforts to combat iNTS disease in more affected areas.

Cost-effectiveness of the top 100 drugs by public spending in Canada, 2015-2021: a repeated cross-sectional study

Por: Gaudette · E. · Rizzardo · S. · Zhang · Y. · Pothier · K. R. · Tadrous · M.
Objectives

To assess the distribution and spending by cost-effectiveness category among those drugs with the highest public spending levels in Canada.

Design

Repeated cross-sectional study.

Setting

The Canadian provinces of Manitoba, Ontario, New Brunswick, Nova Scotia, Prince Edward Island and Newfoundland.

Main outcomes and measures

Cost-effectiveness assessments by the Canadian Agency for Drugs and Technologies in Health (CADTH) for top-100 brand-name outpatient drugs by gross public plan spending in any year between 2015 and 2021 in Canada Institute for Health Information’s National Prescription Drug Utilization Information System data. Gross public plan spending by cost-effectiveness category.

Results

From 2015 to 2021, 152 brand-name drugs occupied a top-100 rank and were included in the analysis. Of those, 117 had been assessed by CADTH. During the 7-year period, there was an increase in both top-100 drugs with cost-effective (from 18 to 24) and cost-ineffective (from 29 to 41) assessments, while drugs not assessed or with an unclear assessment declined (from 31 to 19 and from 22 to 16, respectively). As a share of spending on top-100 drugs with an assessment, spending on cost-effective drugs was mostly stable at 40%–46% from 2015 to 2021, while spending on cost-ineffective drugs increased from 30% to 45%.

Conclusion

A large and growing share of public drug spending has been allocated to cost-ineffective drugs in Canada. Dedicating large budgets to such treatments prevents spending with greater health impact elsewhere in the healthcare system and could restrain the capacity to pay for groundbreaking pharmaceutical innovation in the future.

Investigating patient engagement associations between a postdischarge texting programme and patient experience, readmission and revisit rates outcomes

Por: Bruce · C. · Pinn-Kirkland · T. · Meyers · A. · Javaluyas · E. · Osborn · J. · Kelkar · S. · Bruchhaus · L. · McLaury · K. · Sauceda · K. · Carr · K. · Garcia · C. · Arabie · L. A. · Williams · T. · Vozzella · G. · Nisar · T. · Schwartz · R. L. · Sasangohar · F.
Objectives

This study aimed (1) to examine the association between patient engagement with a bidirectional, semiautomated postdischarge texting programme and Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS) survey outcomes, readmissions and revisit rates in a large health system and (2) to describe operational and clinical flow considerations for implementing a postdischarge texting programme.

Setting

The study involved 1 main academic hospital (beds: 2500+) and 6 community hospitals (beds: 190–400, averaging 300 beds per hospital) in Houston, Texas.

Methods

Retrospective, observational cohort study between non-engaged patients (responded with 0–2 incoming text messages) and engaged patients (responded with 3+ incoming, patient-initiated text messages) between December 2022 and May 2023. We used the two-tailed t-test for continuous variables and 2 test for categorical variables to compare the baseline characteristics between the two cohorts. For the binary outcomes, such as the revisit (1=yes, vs 0=no) and readmissions (1=yes vs 0=no), we constructed mixed effect logistic regression models with the random effects to account for repeated measurements from the hospitals. For the continuous outcome, such as the case mix index (CMI), a generalised linear quantile mixed effect model was built. All tests for significance were two tailed, using an alpha level of 0.05, and 95% CIs were provided. Significance tests were performed to evaluate the CMI and readmissions and revisit rates.

Results

From 78 883 patients who were contacted over the course of this pilot implementation, 49 222 (62.4%) responded, with 39 442 (50%) responded with 3+ incoming text messages. The engaged cohort had higher HCAHPS scores in all domains compared with the non-engaged cohort. The engaged cohort used significantly fewer 30-day acute care resources, experiencing 29% fewer overall readmissions and 20% fewer revisit rates (23% less likely to revisit) and were 27% less likely to be readmitted. The results were statistically significant for all but two hospitals.

Conclusions

This study builds on the few postdischarge texting studies, and also builds on the patient engagement literature, finding that patient engagement with postdischarge texting can be associated with fewer acute care resources. To our knowledge, this is the only study that documented an association between a text-based postdischarge programme and HCAHPS scores, perhaps owing to the bidirectionality and ease with which patients could interact with nurses. Future research should explore the texting paradigms to evaluate their associated outcomes in a variety of postdischarge applications.

Prevalence and determinants of pregnancy termination in Ethiopia: a systematic review and meta-analysis

Por: Kumsa · H. · Mislu · E. K. · Arage · M. W. · Kidie · A. A. · Hailu · T. · Tenaw · L. A.
Objective

This review aims to determine the prevalence of pregnancy termination and its determinant factors in Ethiopia.

Design

Systematic review and meta-analysis.

Data sources

Relevant articles were retrieved from databases such as PubMed, EMBASE, Medline and other search engines.

Eligibility criteria for selecting studies

The research design for this study had no restrictions, allowing for the inclusion of cross-sectional and case–control studies that examined the prevalence or determinants of pregnancy termination. However, case reports, case series, reviews, editorials and studies published as abstracts only were excluded from the analysis.

Data extraction and synthesis

The review was precisely in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses criteria, and the quality of the review was assessed using the Joanna Briggs Institute critical appraisal checklist. Heterogeneity was indicated by the p value for I2 statistics less than 0.05. Data were entered into Microsoft Excel, and the analysis was conducted by using Stata V.16.

Results

The pooled prevalence of pregnancy termination in Ethiopia was 21.52% (95% CI 15.01% to 28.03%). Women who had their first sexual initiation before the age of 18 (OR 1.78; 95% CI 1.13 to 2.82, p=0.14), had irregular menstrual bleeding (OR 1.86; 95% CI 1.25 to 2.77, p=0.76), being a student (OR 4.85; 95% CI 1.98 to 11.91, p=0.20) and had multiple sexual partners (OR 4.88; 95% CI 3.43 to 6.93, p=0.33) were significantly associated with pregnancy termination.

Conclusions

One in five women terminated their pregnancies, which is higher than in other sub-Saharan countries. Being a student, irregular menstrual bleeding, early initiation of sexual intercourse and multiple sexual partners were determinants of pregnancy termination. Special attention is needed in avoiding early sexual initiation and in reducing sexual risk behaviours.

Low-value MRI of the knee in Norway: a register-based study to identify the proportion of potentially low-value MRIs and estimate the related costs

Por: Hofmann · B. · Havik · V. · Andersen · E. R. · Brandsaeter · I. O. · Kjelle · E.
Objectives

The objective of this study is to investigate the proportion of potentially low-value knee MRI in Norway and to provide an estimate of the related costs.

Design

Register study based on conditional data extraction and analysis of data from Control and Reimbursement of Healthcare Claims registry in Norway.

Setting

MRI in public specialist healthcare with universal health coverage (Norway).

Participants

48 212 MRIs for 41 456 unique patients and 45 946 reimbursement claims.

Outcome measures

Proportion of MRIs of the knee that (1) did not have a relevant tentative diagnosis prior to the knee MRI, (2) did not have a relevant alternative image of the knee before the MRI or (3) did not have a relevant code from the specialist care within 6 months after the MRI, and those that had combinations of 1, 2 and 3. Estimated costs for those that had combinations of 1, 2 and 3.

Results

Very few patients (6.4%) had a relevant diagnosis code or prior imaging examination when having the MRI and only 14.6% got a knee-related diagnosis code from the specialist care within 6 months after the MRI. 21.8% of the patients had knee X-ray, CT or ultrasound within 6 months before the MRI. Between 58% and 85% of patients having knee MRIs in Norway have no relevant examinations or diagnoses six months prior to or after the MRI examination. These examinations are unlikely to benefit patients and they correspond to between 24 108 and 35 416 MRIs at a cost of 6.7–9.8 million per year.

Conclusion

A substantial proportion of MRIs of the knee in Norway have no relevant examinations or diagnoses before or after the MRI and are potentially of low value. Reducing low-value MRIs could free resources for high-value imaging, reduce waiting times, improve the quality of care and increase patient safety and professional integrity.

Cohort profile: BioMD-Y (biopsychosocial factors of major depression in youth) - a biobank study on the molecular genetics and environmental factors of depression in children and adolescents in Munich

Por: Scherff · A. D. · Feldmann · L. · Piechaczek · C. · Pehl · V. · Wagenbüchler · P. · Wermuth · I. · Ghotbi · N. · Allgaier · A.-K. · Freisleder · F. J. · Beins · E. C. · Forstner · A. J. · Nöthen · M. M. · Czamara · D. · Rex-Haffner · M. · Ising · M. · Binder · E. · Greimel · E. · Sch
Purpose

BioMD-Y is a comprehensive biobank study of children and adolescents with major depression (MD) and their healthy peers in Germany, collecting a host of both biological and psychosocial information from the participants and their parents with the aim of exploring genetic and environmental risk and protective factors for MD in children and adolescents.

Participants

Children and adolescents aged 8–18 years are recruited to either the clinical case group (MD, diagnosis of MD disorder) or the typically developing control group (absence of any psychiatric condition).

Findings to date

To date, four publications on both genetic and environmental risk and resilience factors (including FKBP5, glucocorticoid receptor activation, polygenic risk scores, psychosocial and sociodemographic risk and resilience factors) have been published based on the BioMD-Y sample.

Future plans

Data collection is currently scheduled to continue into 2026. Research questions will be further addressed using available measures.

Reinforcing informed medication prescription for low back pain in the emergency department (RIME): a controlled interrupted time series implementation study protocol

Por: O'Leary · S. · Heine · J. · Warren · J. · Smyth · T. · Ballard · E. · Mitchell · G. · See · W. · Barlas · P. · Machado · G. C. · Cottrell · M. · Comans · T. · Foster · N. E.
Introduction

Management guidelines for low back pain (LBP) recommend exclusion of serious pathology, followed by simple analgesics, superficial heat therapy, early mobilisation and patient education. An audit in a large metropolitan hospital emergency department (ED) revealed high rates of non-recommended medication prescription for LBP (65% of patients prescribed opioids, 17% prescribed benzodiazepines), high inpatient admission rates (20% of ED LBP patients), delayed patient mobilisation (on average 6 hours) and inadequate patient education (48% of patients). This study aims to improve medication prescription for LBP in this ED by implementing an intervention shown previously to improve guideline-based management of LBP in other Australian EDs.

Methods and analysis

A controlled interrupted time series study will evaluate the intervention in the ED before (24 weeks; 20 March 2023–3 September 2023) and after (24 weeks; 27 November 2024–12 May 2024) implementation (12 weeks; 4 September 2023–26 November 2023), additionally comparing findings with another ED in the same health service. The multicomponent implementation strategy uses a formalised clinical flow chart to support clinical decision-making and aims to change clinician behaviour, through clinician education, provision of alternative treatments, educational resources, audit and feedback, supported by implementation champions. The primary outcome is the percentage of LBP patients prescribed non-recommended medications (opioids, benzodiazepines and/or gabapentinoids), assessed via routinely collected ED data. Anticipated sample size is 2000 patients (n=1000 intervention, n=1000 control) based on average monthly admissions of LBP presentations in the EDs. Secondary outcomes include inpatient admission rate, time to mobilisation, provision of patient education, imaging requests, representation to the ED within 6 months and healthcare costs. In nested qualitative research, we will study ED clinicians’ perceptions of the implementation and identify how benefits can be sustained over time.

Ethics and dissemination

This study received ethical approval from the Metro North Human Research Ethics Committee (HREC/2022/MNHA/87995). Study findings will be published in peer-reviewed journals and presented at international conferences and educational workshops.

Objectives

Tuberculosis infection (TBI) is marked by dynamic host–pathogen interactions with persistent low-grade inflammation and is associated with increased risk of cardiovascular diseases (CVD) including acute coronary syndrome, myocardial infarction and stroke. However, few studies assess the relationship between TBI and hypertension, an intermediate of CVD. We sought to determine the association between TBI and hypertension using data representative of the adult US population.

Methods

We performed cross-sectional analyses using data from the 2011–2012 US National Health and Nutrition Examination Survey (NHANES). Eligible participants included adults with valid QuantiFERON-TB Gold In-Tube (QFT-GIT) test results who also had blood pressure measures and no history of TB disease. TBI was defined by a positive QFT-GIT. We defined hypertension by either elevated measured blood pressure levels (ie, systolic ≥130 mm Hg or diastolic ≥80 mm Hg) or known hypertension indications (ie, self-reported previous diagnosis or use of antihypertensive medications). Analyses were performed using robust quasi-Poisson regressions and accounted for the stratified probability sampling design of NHANES.

Results

The overall prevalence of TBI was 5.7% (95% CI 4.7% to 6.7%) and hypertension was present among 48.9% (95% CI 45.2% to 52.7%) of participants. The prevalence of hypertension was higher among those with TBI (58.5%, 95% CI 52.4% to 64.5%) than those without TBI (48.3%, 95% CI 44.5% to 52.1%) (prevalence ratio (PR) 1.2, 95% CI 1.1 to 1.3). However, after adjusting for confounders, the prevalence of hypertension was similar for those with and without TBI (adjusted PR 1.0, 95% CI 1.0 to 1.1). The unadjusted prevalence of hypertension was higher among those with TBI versus no TBI, especially among individuals without CVD risk factors including those with normal body mass index (PR 1.6, 95% CI 1.2 to 2.0), euglycaemia (PR 1.3, 95% CI 1.1 to 1.5) or non-smokers (PR 1.2, 95% CI 1.1 to 1.4).

Conclusions

More than half of adults with TBI in the USA had hypertension. Importantly, we observed a relationship between TBI and hypertension among those without established CVD risk factors.

Summary

The prevalence of hypertension was high (59%) among adults with TBI in the USA. In addition, we found that the prevalence of hypertension was significantly higher among adults with positive QFT without established hypertension risk factors.

Introduction

Seasonal malaria chemoprevention (SMC) involves repeated administrations of sulfadoxine-pyrimethamine plus amodiaquine to children below the age of 5 years during the peak transmission season in areas of seasonal malaria transmission. While highly impactful in reducing Plasmodium falciparum malaria burden in controlled research settings, the impact of SMC on infection prevalence is moderate in real-life settings. It remains unclear what drives this efficacy decay. Recently, the WHO widened the scope for SMC to target all vulnerable populations. The Ministry of Health (MoH) in Burkina Faso is considering extending SMC to children below 10 years old. We aim to assess the impact of SMC on clinical incidence and parasite prevalence and quantify the human infectious reservoir for malaria in this population.

Methods and analysis

We will perform a cluster randomised trial in Saponé Health District, Burkina Faso, with three study arms comprising 62 clusters of three compounds: arm 1 (control): SMC in under 5-year-old children, implemented by the MoH without directly observed treatment (DOT) for the full course of SMC; arm 2 (intervention): SMC in under 5-year-old children, with DOT for the full course of SMC; arm 3 (intervention): SMC in under 10-year-old children, with DOT for the full course of SMC. The primary endpoint is parasite prevalence at the end of the malaria transmission season. Secondary endpoints include the impact of SMC on clinical incidence. Factors affecting SMC uptake, treatment adherence, drug concentrations, parasite resistance markers and transmission of parasites will be determined.

Ethics and dissemination

The London School of Hygiene & Tropical Medicine’s Ethics Committee (29193) and the Burkina Faso National Medical Ethics Committee (Deliberation No 2023-05-104) approved this study. The findings will be presented to the community; disease occurrence data and study outcomes will also be shared with the Burkina Faso MoH. Findings will be published irrespective of their results.

Protocol: Prospective evaluation of feasibility, added value and satisfaction of remote digital self-assessment for mild cognitive impairment in routine care with the neotivCare app

Por: Duzel · E. · Schöttler · M. · Sommer · H. · Griebe · M.
Introduction

Timely diagnosis of mild cognitive impairment (MCI) in Alzheimer’s disease is crucial for early interventions, but its implementation is often challenging due to the complexity and time burden of required cognitive assessments. To address these challenges, the usability of new unsupervised digital remote assessment tools needs to be validated in a care context.

Methods and analysis

This multicentric healthcare research evaluation survey, re.cogni.ze, aims to evaluate physician satisfaction with a remote digital assessment solution (neotivCare) in primary and specialised routine care in Germany. Over a period of 22 months, physicians in different regions of Germany will recommend the application (app) to approximately 1000 patients for a 12-week self-assessment of cognition. The primary endpoint is the evaluation of physicians’ and patients’ overall satisfaction with neotivCare and with neuropsychological questionnaires/standard procedures using a Likert scale, while secondary endpoints include user-friendliness, qualitative assessment of acceptance and potential improvements on medical routine services. The study also aims to evaluate the proportion of physicians or patients attributing added value to neotivCare compared with standard paper–pencil tests. The study results will provide insights into the feasibility, efficiency and acceptance of new digital tools for MCI diagnosis in routine care. The re.cogni.ze survey will thus provide proof-of-concept information for the implementation of remote digital cognitive assessment apps for MCI into medical routine care.

Ethics and dissemination

This study was approved by the ethics committee of the State Medical Association (Landesärztekammer) Baden-Württemberg, (F-2021-161) as the leading committee and nine ethics committees local to the participating healthcare professionals (Lower Saxony, North Rhine, Westphalia-Lippe, Hesse, Bremen, Berlin, University of Göttingen, Charite, University of Rostock). The results can be shared (upon reasonable quest) to improve routine clinical processes and holistic approaches.

Changes in medical student attendance and its impact on student educational outcomes: a systematic review protocol

Introduction

The COVID-19 pandemic has had a significant impact on medical education, with many institutions shifting to online learning to ensure the safety of students and staff. However, there has been a decline in in-person attendance at medical schools across the UK and worldwide following the relaxation of social distancing rules and the reinstation of in-person teaching. Importantly, this trend has been observed prior to the pandemic. While reflected within the literature, there is currently no systematic review describing these changes. We aim to find out how medical students’ attendance is changing as documented within the literature and its impact on their educational outcomes.

Methods and analysis

This systematic review will follow the guidelines of the Centre of Research and Dissemination, Meta-analyses of Observational Studies in Epidemiology and Preferred Reporting Items for Systematic Reviews and Meta-Analyses. We will search the major databases of Medline via Ovid, Embase via Ovid, Scopus, Web of Science, British Education Index via EBSCOhost and ERIC via EBSCOhost.

Two reviewers will independently screen each paper and extract data, with a third reviewer for dispute resolution. All studies reporting on medical students from various universities, both graduate and undergraduate and describing changes in attendance and/or students‘ educational outcomes will be included. Risk of bias in individual studies will be assessed using the Newcastle-Ottawa Scale and confidence in cumulative evidence will be evaluated using the Grading of Recommendations, Assessment, Development and Evaluation-Confidence in the Evidence from Reviews of Qualitative Research approach. A narrative synthesis of the findings from all included studies will be reported.

Ethics and dissemination

Ethical approval is not required for this systematic review of existing publicly available literature. We will subsequently aim to publish the results of this systematic review in a peer-reviewed journal.
