Skin closUre in carPal tunnEl Release (SUPER): protocol for a blinded randomised controlled trial comparing absorbable and non-absorbable sutures in carpal tunnel release

Por: Savolainen · A. · Nietosvaara · Y. · Sirola · J. · Hytönen · M. · Reito · A. · Heikkinen · N. · Räisänen · M. P.
Introduction

Carpal tunnel syndrome is a common disorder affecting a substantial portion of the general population. Surgical intervention is often deemed necessary, with the median nerve release being one of the most frequent operations. Optimising all the aspects of this procedure can enhance patient satisfaction with the treatment.

Methods and analysis

We aim to determine the differences in the aesthetic outcome of the scar as well as the pain experienced during the healing process between the use of absorbable and non-absorbable sutures. The primary outcome measure will be the patients’ subjective satisfaction with the aesthetic appearance of the scar 1 year after the operation. Secondary outcomes will include a similar evaluation of the aesthetics performed by a blinded outcome assessor, as well as pain experienced by the patients during the 2 weeks postoperatively. The severity and improvement of the patients’ symptoms will also be measured by a Finnish version of the Boston Carpal Tunnel Questionnaire. Costs will be evaluated for both groups. Safety of the wound closure will be followed and reported.

Ethics and dissemination

This protocol was approved by the Research Ethics Committee of the Northern Savo Hospital District (2319/2021). The trial will be conducted in accordance with the principles of Good Clinical Practice and the Declaration of Helsinki. The results will be disseminated through publication in peer-reviewed journals.

Multicentre double-blind randomised placebo-controlled trial evaluating the efficacy of the meningococcal B vaccine, 4CMenB (Bexsero), against Neisseria gonorrhoeae infection in men who have sex with men: the GoGoVax study protocol

Por: Seib · K. L. · Donovan · B. · Thng · C. · Lewis · D. A. · McNulty · A. · Fairley · C. K. · Yeung · B. · Jin · F. · Fraser · D. · Bavinton · B. R. · Law · M. · Chen · M. Y. · Chow · E. P. F. · Whiley · D. M. · Mackie · B. · Jennings · M. P. · Jennison · A. V. · Lahra · M. M. · Grulich · A. E
Introduction

Gonorrhoea, the sexually transmissible infection caused by Neisseria gonorrhoeae, has a substantial impact on sexual and reproductive health globally with an estimated 82 million new infections each year worldwide. N. gonorrhoeae antimicrobial resistance continues to escalate, and disease control is largely reliant on effective therapy as there is no proven effective gonococcal vaccine available. However, there is increasing evidence from observational cohort studies that the serogroup B meningococcal vaccine four-component meningitis B vaccine (4CMenB) (Bexsero), licensed to prevent invasive disease caused by Neisseria meningitidis, may provide cross-protection against the closely related bacterium N. gonorrhoeae. This study will evaluate the efficacy of 4CMenB against N. gonorrhoeae infection in men (cis and trans), transwomen and non-binary people who have sex with men (hereafter referred to as GBM+).

Methods and analysis

This is a double-blind, randomised placebo-controlled trial in GBM+, either HIV-negative on pre-exposure prophylaxis against HIV or living with HIV (CD4 count >350 cells/mm3), who have had a diagnosis of gonorrhoea or infectious syphilis in the last 18 months (a key characteristic associated with a high risk of N. gonorrhoeae infection). Participants are randomised 1:1 to receive two doses of 4CMenB or placebo 3 months apart. Participants have 3-monthly visits over 24 months, which include testing for N. gonorrhoeae and other sexually transmissible infections, collection of demographics, sexual behaviour risks and antibiotic use, and collection of research samples for analysis of N. gonorrhoeae-specific systemic and mucosal immune responses. The primary outcome is the incidence of the first episode of N. gonorrhoeae infection, as determined by nucleic acid amplification tests, post month 4. Additional outcomes consider the incidence of symptomatic or asymptomatic N. gonorrhoeae infection at different anatomical sites (ie, urogenital, anorectum or oropharynx), incidence by N. gonorrhoeae genotype and antimicrobial resistance phenotype, and level and functional activity of N. gonorrhoeae-specific antibodies.

Ethics and dissemination

Ethical approval was obtained from the St Vincent’s Hospital Human Research Ethics Committee, St Vincent’s Hospital Sydney, NSW, Australia (ref: 2020/ETH01084). Results will be disseminated in peer-reviewed journals and via presentation at national and international conferences.

Alpha 2 agonists for sedation to produce better outcomes from critical illness (A2B trial): protocol for a mixed-methods process evaluation of a randomised controlled trial

Por: Aitken · L. M. · Emerson · L. M. · Kydonaki · K. · Blackwood · B. · Creagh-Brown · B. · Lone · N. I. · McKenzie · C. A. · Reade · M. C. · Weir · C. J. · Wise · M. P. · Walsh · T. S.
Introduction

An association between deep sedation and adverse short-term outcomes has been demonstrated although this evidence has been inconsistent. The A2B (alpha-2 agonists for sedation in critical care) sedation trial is designed to determine whether the alpha-2 agonists clonidine and dexmedetomidine, compared with usual care, are clinically and cost-effective. The A2B intervention is a complex intervention conducted in 39 intensive care units (ICUs) in the UK. Multicentre organisational factors, variable cultures, perceptions and practices and the involvement of multiple members of the healthcare team add to the complexity of the A2B trial. From our pretrial contextual exploration it was apparent that routine practices such as type and frequency of pain, agitation and delirium assessment, as well as the common sedative agents used, varied widely across the UK. Anticipated challenges in implementing A2B focused on the impact of usual practice, perceptions of risk, ICU culture, structure and the presence of equipoise. Given this complexity, a process evaluation has been embedded in the A2B trial to uncover factors that could impact successful delivery and explore their impact on intervention delivery and interpretation of outcomes.

Methods and analysis

This is a mixed-methods process evaluation guided by the A2B intervention logic model. It includes two phases of data collection conducted during and at the end of trial. Data will be collected using a combination of questionnaires, stakeholder interviews and routinely collected trial data. A framework approach will be used to analyse qualitative data with synthesis of data within and across the phases. The nature of the relationship between delivery of the A2B intervention and the trial primary and secondary outcomes will be explored.

Ethics and dissemination

All elements of the A2B trial, including the process evaluation, are approved by Scotland A Research Ethics Committee (Ref. 18/SS/0085). Dissemination will be via publications, presentations and media engagement.

Cohort profile: The Health, Food, Purchases and Lifestyle (SMIL) cohort - a Danish open cohort

Por: Sorensen · K. K. · Andersen · M. P. · Moller · F. T. · Eves · C. · Junker · T. G. · Zareini · B. · Torp-Pedersen · C.
Purpose

The Health, Food, Purchases and Lifestyle (SMIL) cohort is a prospective open Danish cohort that collects electronic consumer purchase data, which can be linked to Danish nationwide administrative health and social registries. This paper provides an overview of the cohort’s baseline characteristics and marginal differences in the monetary percentage spent on food groups by sex, age and hour of the day.

Participants

As of 31 December 2022, the cohort included 11 214 users of a smartphone-based receipt collection application who consented to share their unique identification number for linkage to registries in Denmark. In 2022, the composition of the cohort was as follows: 62% were men while 24% were aged 45–55. The cohort had a median of 63 (IQR 26–116) unique shopping trips. The cohort included participants with a range of health statuses. Notably, 21% of participants had a history of cardiovascular disease and 8% had diabetes before donating receipts.

Findings to date

The feasibility of translating consumer purchase data to operationalisable food groups and merging with registers has been demonstrated. We further demonstrated differences in marginal distributions which revealed disparities in the amount of money spent on various food groups by sex and age, as well as systematic variations by the hour of the day. For example, men under 30 spent 8.2% of their total reported expenditure on sugary drinks, while women under 30 spent 6.5%, men over 30 spent 4.3% and women over 30 spent 3.9%.

Future plans

The SMIL cohort is characterised by its dynamic, continuously updated database, offering an opportunity to explore the relationship between diet and disease without the limitations of self-reported data. Currently encompassing data from 2018 to 2022, data collection is set to continue. We expect data collection to continue for many years and we are taking several initiatives to increase the cohort.

What do spouse primary caregivers of patients with glioblastoma want medical providers to know? A qualitative thematic reflexive analysis of letters written by primary caregivers from a secret Facebook support group

Por: Coman · D. L. · Chard · M. P. · Desautels · L. · Lutz · B. J. · Minns · L. A.
Objectives

To analyse the content of letters written by female spouse primary caregivers of patients with glioblastoma multiforme (GBM), a devastating and terminal primary brain cancer, and give voice to their experiences for medical providers of patients with GBM.

Design

A qualitative study using reflexive thematic analysis of letters written by female spouses/life partners and primary caregivers of patients with GBM.

Participants

101 current or former female spouse primary caregivers of patients with GBM wrote letters to share with the medical community between July 2019 and August 2019. Inclusion criteria: (1) the primary caregiver who is a spouse of a patient with glioblastoma, (2) be a member of the secret Facebook group, ‘We are the wives of GBM and this is our story’, and (3) completed informed consent for the contents of their letter to be included for primary and secondary data analysis. Participants who wrote letters but did not complete the informed consent were excluded from the study.

Results

Themes from the letters included the patient experiences: (1) medical details of the disease trajectory, (2) interactions of the patient/caregiver dyads with healthcare and (3) the changing patient condition over time. Themes focused on the caregiver experiences: (1) caregiver challenges, (2) caregiver responses and (3) caregiver coping strategies, and description of tangible needs that would help other caregivers in the future. Caregiver needs were highest during the living with disease progression phase. Caregivers wanted more education and to be valued as members of the care team.

Conclusion

Shared decision-making through family-centred care would be beneficial for primary caregivers of patients with GBM. These findings provide opportunities to guide more timely and tailored interventions to provide support and improve care for patient/caregiver dyads to help mitigate the burden of this progressive disease and improve quality of life for caregivers.

Do school-based smoking preventive interventions have unintended effects? Post hoc analysis of the Focus cluster randomised controlled trial

Por: Kjeld · S. G. · Thygesen · L. C. · Danielsen · D. · Jensen · M. P. · Krolner · R. F. · Pisinger · C. · Andersen · S.
Objectives

Public health interventions are designed to improve specific health-related outcomes; however, they may also produce negative side effects, such as substitution use, psychological or social harms. Knowledge about the unintended effects of school-based smoking preventive interventions is sparse. Hence, this study examined these potential unintended effects of the smoking-reducing intervention, Focus, among students in the vocational education and training setting.

Design

Cluster randomised controlled trial stratified by school type with 5 months follow-up.

Setting and participants

Across Denmark, eight schools were randomised to the intervention group (n=844 students, response proportion 76%) and six schools to the control group (n=815 students, response proportion 75%). This study focused solely on students who smoked at baseline (N=491).

Interventions

The intervention was developed systematically based on theory and a thoroughly mixed-methods needs assessment. Intervention components included a comprehensive school tobacco policy (smoke-free school hours) supported by a 3-day course for school staff and launched by an edutainment session for students; class-based lessons and a quit-and-win competition; and individual telephone smoking cessation support.

Outcomes

Alternative tobacco and nicotine products (regular use of smokeless tobacco, hookah and e-cigarettes), regular cannabis use, boredom and loneliness at school, stress and perceived stigmatisation among smokers.

Results

We found no statistically significant unintended effects of the intervention. Nonetheless, insignificant findings indicated that students in the intervention group were less likely to be bored during school hours (OR 0.59, 95% CI 0.32 to 1.10) and experience stress (OR 0.62, 95% CI 0.35 to 1.10), but more likely to report feeling stigmatised compared with the control group (OR 1.55, 95% CI 0.71 to 3.40).

Conclusions

Overall, findings suggested no unintended effects of the Focus trial with respect to substitution use, psychological, nor group or social harms. Future research is encouraged to report potential harmful outcomes of smoking preventive interventions, and interventions should be aware of the possible stigmatisation of smokers.

Impact of COVID-19 on diabetes care: mixed methods study in an Indigenous area of Guatemala

Por: Guarchaj · M. · Tschida · S. · Milian Chew · J. P. · Aguilar · A. · Flood · D. · Fort · M. P. · Morales · L. C. · Mendoza Montano · C. · Rodriguez Serrano · S. N. · Rohloff · P.
Introduction

SARS-CoV-2 has impacted globally the care of chronic diseases. However, direct evidence from certain vulnerable communities, such as Indigenous communities in Latin America, is missing. We use observational data from a health district that primarily serves people of Maya K’iche’ ethnicity to examine the care of type 2 diabetes in Guatemala during the pandemic.

Methods

We used a parallel convergent mixed methods design. Quantitative data (n=142 individuals with diabetes) included glycated haemoglobin (HbA1c), blood pressure, body mass index and questionnaires on diabetes knowledge, self-care and diabetes distress. Quantitative data was collected at two points, at baseline and after COVID restrictions were lifted. For quantitative outcomes, we constructed multilevel mixed effects models with multiple imputation for missing data. Qualitative data included interviews with providers, supervisors and individuals living with diabetes (n=20). We conducted thematic framework analysis using an inductive approach.

Results

Quantitative data was collected between June 2019 and February 2021, with a median of 487 days between data collection points. HbA1c worsened +0.54% (95% CI, 0.14 to 0.94) and knowledge about diabetes decreased –3.54 points (95% CI, –4.56 to –2.51). Qualitatively, the most important impact of the pandemic was interruption of the regular timing of home visits and peer group meetings which were the standard of care.

Conclusions

The deterioration of diabetes care was primarily attributed to the loss of regular contact with healthcare workers. The results emphasize the vulnerability of rural and Indigenous populations in Latin America to the suspension of chronic disease care.

Exploring perceptions and operational considerations for use of a smartphone application to self-monitor blood pressure in pregnancy in Lombok, Indonesia: protocol for a qualitative study

Por: Tamrat · T. · Setiyawati · Y. D. · Barreix · M. · Gayatri · M. · Rinjani · S. O. · Pasaribu · M. P. · Geissbuhler · A. · Shankar · A. H. · Tuncalp · O.
Introduction

Hypertensive disorders of pregnancy (HDP) are a leading cause of maternal deaths globally and require close monitoring of blood pressure (BP) to mitigate potential adverse effects. Despite the recognised need for research on self-monitoring of blood pressure (SMBP) among pregnant populations, there are very few studies focused on low and middle income contexts, which carry the greatest burden of HDPs. The study aims to understand the perceptions, barriers, and operational considerations for using a smartphone software application to perform SMBP by pregnant women in Lombok, Indonesia.

Methods and analysis

This study includes a combination of focus group discussions, in-depth interviews and workshop observations. Pregnant women will also be provided with a research version of the smartphone BP application to use in their home and subsequently provide feedback on their experiences. The study will include pregnant women with current or past HDP, their partners and the healthcare workers involved in the provision of antenatal care services within the catchment area of six primary healthcare centres. Data obtained from the interviews and observations will undergo thematic analyses using a combination of both inductive and deductive approaches.

Ethics and dissemination

The study was approved by the World Health Organization (WHO) and Human Reproduction Programme (HRP) Research Project Review Panel and WHO Ethical Review Committee (A65932) as well as the Health Research Ethics Committee, Faculty of Medicine, Universitas Mataram in Indonesia (004/UN18/F7/ETIK/2023).

Findings will be disseminated through research publications and communicated to the Lombok district health offices. The analyses from this study will also inform the design of a subsequent impact evaluation.

Associations of eHealth literacy and knowledge with preventive behaviours and psychological distress during the COVID-19 pandemic: a population-based online survey

Por: Lee · J. J. · Poon · C. Y. · O'Connor · S. · Wong · J. Y. H. · Kwok · J. Y. Y. · Choi · E. P. H. · Tsang · W. N. · Wang · M. P.
Objectives

To compare the associations of COVID-19 preventive behaviours and depressive and anxiety symptoms with eHealth literacy and COVID-19 knowledge among Korean adults.

Design

A cross-sectional online survey was conducted in April 2020.

Setting

Seoul metropolitan area in South Korea.

Participants

1057 Korean adults were recruited.

Main outcome measures

Associations between eHealth literacy, COVID-19 knowledge, COVID-19 preventive behaviours and psychological distress were computed using Pearson’s correlation and logistic regression analyses. eHealth literacy, COVID-19 knowledge, COVID-19 preventive behaviours and psychological distress were weighted by sex and age distribution of the general population in Seoul Metropolitan area.

Results

68.40% (n=723) perceived high eHealth literacy level (eHEALS ≥26), while 57.43% (n=605) had high levels of COVID-19 knowledge (score ≥25). No significant association between eHealth literacy and COVID-19 knowledge was identified (r=0.05, p=0.09). eHealth literacy and COVID-19 knowledge were significantly associated with COVID-19 preventive behaviours (aOR=1.99, 95% CI 1.51 to 2.62 L; aOR=1.81, 95% CI 1.40 to 2.34, respectively). High eHealth literacy was significantly associated with anxiety symptom (aOR=1.71, 95% CI 1.18 to 2.47) and depressive symptom (aOR=1.69, 95% CI 1.24 to 2.30). COVID-19 knowledge had negative and no associations with the symptoms (aOR=0.62, 95% CI 0.46 to 0.86; aOR=0.79, 95% CI 0.60 to 1.03, respectively). High eHealth literacy with low COVID-19 knowledge was positively and significantly associated with COVID-19 preventive behaviours (aOR=2.30, 95% CI 1.52 to 3.43), and anxiety (aOR=1.81, 95% CI 1.09 to 3.01) and depressive symptoms (aOR=2.24, 95% CI 1.41 to 3.55). High eHealth literacy with high COVID-19 knowledge were significantly associated with more preventive behaviours (aOR=3.66, 95% CI 2.47 to 5.42) but no significant associations with anxiety and depressive symptoms.

Conclusion

We identified that eHealth literacy and COVID-19 knowledge were not associated each other, and differently associated with individuals’ COVID-19 preventive behaviours and psychological well-being. Public health strategies should pay attention to enhancing both eHealth literacy and COVID-19 knowledge levels in the public to maximise their COVID-19 preventive behaviours and mitigate their psychological distress during COVID-19 pandemic.

Alpha 2 agonists for sedation to produce better outcomes from critical illness (A2B Trial): protocol for a multicentre phase 3 pragmatic clinical and cost-effectiveness randomised trial in the UK

Por: Walsh · T. S. · Aitken · L. M. · McKenzie · C. A. · Boyd · J. · Macdonald · A. · Giddings · A. · Hope · D. · Norrie · J. · Weir · C. · Parker · R. A. · Lone · N. I. · Emerson · L. · Kydonaki · K. · Creagh-Brown · B. · Morris · S. · McAuley · D. F. · Dark · P. · Wise · M. P. · Gordon · A. C.
Introduction

Almost all patients receiving mechanical ventilation (MV) in intensive care units (ICUs) require analgesia and sedation. The most widely used sedative drug is propofol, but there is uncertainty whether alpha2-agonists are superior. The alpha 2 agonists for sedation to produce better outcomes from critical illness (A2B) trial aims to determine whether clonidine or dexmedetomidine (or both) are clinically and cost-effective in MV ICU patients compared with usual care.

Methods and analysis

Adult ICU patients within 48 hours of starting MV, expected to require at least 24 hours further MV, are randomised in an open-label three arm trial to receive propofol (usual care) or clonidine or dexmedetomidine as primary sedative, plus analgesia according to local practice. Exclusions include patients with primary brain injury; postcardiac arrest; other neurological conditions; or bradycardia. Unless clinically contraindicated, sedation is titrated using weight-based dosing guidance to achieve a Richmond-Agitation-Sedation score of –2 or greater as early as considered safe by clinicians. The primary outcome is time to successful extubation. Secondary ICU outcomes include delirium and coma incidence/duration, sedation quality, predefined adverse events, mortality and ICU length of stay. Post-ICU outcomes include mortality, anxiety and depression, post-traumatic stress, cognitive function and health-related quality of life at 6-month follow-up. A process evaluation and health economic evaluation are embedded in the trial.

The analytic framework uses a hierarchical approach to maximise efficiency and control type I error. Stage 1 tests whether each alpha2-agonist is superior to propofol. If either/both interventions are superior, stages 2 and 3 testing explores which alpha2-agonist is more effective. To detect a mean difference of 2 days in MV duration, we aim to recruit 1437 patients (479 per group) in 40–50 UK ICUs.

Ethics and dissemination

The Scotland A REC approved the trial (18/SS/0085). We use a surrogate decision-maker or deferred consent model consistent with UK law. Dissemination will be via publications, presentations and updated guidelines.

Effect of synchronous remote-based interventions on suicidal behaviours: protocol for a systematic review and meta-analysis

Por: Comendador · L. · Jimenez-Villamizar · M. P. · Losilla · J.-M. · Sanabria-Mazo · J. P. · Mateo-Canedo · C. · Cebria · A. I. · Sanz · A. · Palao · D. J.
Introduction

Suicide is among the leading causes of preventable death worldwide. The impact of suicide affects the personal, social and economic levels. Therefore, its prevention is a priority for public health systems. Previous studies seem to support the efficacy of providing active contact to people who have made a suicide attempt. The current systematic review and meta-analysis aims to investigate the efficacy of distance suicide prevention strategies implemented through synchronous technology-based interventions.

Methods and analysis

This protocol is designed according to the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols. The bibliographical searches were conducted in the databases PubMed, PsycINFO, Scopus and Web of Science in April 2022, with no restrictions on the time of publication and limited to publications in English or Spanish. The search strategy was performed using free-text terms and Medical Subject Headings terms: suicide, follow-up, synchronous, remote, telehealth, telephone, hotline, video-conference and text message. Two reviewers will independently conduct study screening, selection process, data extraction and risk of bias assessment. The analysis and synthesis of the results will be both qualitative and quantitative. A narrative synthesis, presented in a comprehensive table, will be performed and meta-analysis will be conducted, as appropriate, if sufficient data are provided.

Ethics and dissemination

The present review and meta-analysis will not require ethical approval, as it will use data collected from previously published primary studies. The findings of this review will be published in peer-reviewed journals and widely disseminated.

WHY STOP? A prospective observational vignette-based study to determine the cognitive-behavioural effects of rapid diagnostic PCR-based point-of-care test results on antibiotic cessation in ICU infections

Por: Singh · S. · Nurek · M. · Mason · S. · Moore · L. S. · Mughal · N. · Vizcaychipi · M. P.
Objectives

Point-of-care tests (POCTs) for infection offer accurate rapid diagnostics but do not consistently improve antibiotic stewardship (ASP) of suspected ventilator-associated pneumonia. We aimed to measure the effect of a negative PCR-POCT result on intensive care unit (ICU) clinicians’ antibiotic decisions and the additional effects of patient trajectory and cognitive-behavioural factors (clinician intuition, dis/interest in POCT, risk averseness).

Design

Observational cohort simulation study.

Setting

ICU.

Participants

70 ICU consultants/trainees working in UK-based teaching hospitals.

Methods

Clinicians saw four case vignettes describing patients who had completed a course of antibiotics for respiratory infection. Vignettes comprised clinical and biological data (ie, white cell count, C reactive protein), varied to create four trajectories: clinico-biological improvement (the ‘improvement’ case), clinico-biological worsening (‘worsening’), clinical improvement/biological worsening (‘discordant clin better’), clinical worsening/biological improvement (‘discordant clin worse’). Based on this, clinicians made an initial antibiotics decision (stop/continue) and rated confidence (6-point Likert scale). A PCR-based POCT was then offered, which clinicians could accept or decline. All clinicians (including those who declined) were shown the result, which was negative. Clinicians updated their antibiotics decision and confidence.

Measures

Antibiotics decisions and confidence were compared pre-POCT versus post-POCT, per vignette.

Results

A negative POCT result increased the proportion of stop decisions (54% pre-POCT vs 70% post-POCT, 2(1)=25.82, p

Conclusions

A negative PCR-POCT result can encourage antibiotic cessation in ICU, notably in cases of clinical worsening (where the inclination might otherwise be to continue). This effect may be reduced by high clinician confidence to continue and/or disinterest in POCT, perhaps due to low trust/perceived utility. Such cognitive-behavioural and trajectorial factors warrant greater consideration in future ASP study design.

Angiotensin II in liver transplantation (AngLT-1): protocol of a randomised, double-blind, placebo-controlled trial

Por: Bokoch · M. P. · Tran · A. T. · Brinson · E. L. · Marcus · S. G. · Reddy · M. · Sun · E. · Roll · G. R. · Pardo · M. · Fields · S. · Adelmann · D. · Kothari · R. P. · Legrand · M.
Introduction

Catecholamine vasopressors such as norepinephrine are the standard drugs used to maintain mean arterial pressure during liver transplantation. At high doses, catecholamines may impair organ perfusion. Angiotensin II is a peptide vasoconstrictor that may improve renal perfusion pressure and glomerular filtration rate, a haemodynamic profile that could reduce acute kidney injury. Angiotensin II is approved for vasodilatory shock but has not been rigorously evaluated for treatment of hypotension during liver transplantation. The objective is to assess the efficacy of angiotensin II as a second-line vasopressor infusion during liver transplantation. This trial will establish the efficacy of angiotensin II in decreasing the dose of norepinephrine to maintain adequate blood pressure. Completion of this study will allow design of a follow-up, multicentre trial powered to detect a reduction of organ injury in liver transplantation.

Methods and analysis

This is a double-blind, randomised clinical trial. Eligible subjects are adults with a Model for End-Stage Liver Disease Sodium Score ≥25 undergoing deceased donor liver transplantation. Subjects are randomised 1:1 to receive angiotensin II or saline placebo as the second-line vasopressor infusion. The study drug infusion is initiated on reaching a norepinephrine dose of 0.05 µg kg-1 min-1 and titrated per protocol. The primary outcome is the dose of norepinephrine required to maintain a mean arterial pressure ≥65 mm Hg. Secondary outcomes include vasopressin or epinephrine requirement and duration of hypotension. Safety outcomes include incidence of thromboembolism within 48 hours of the end of surgery and severe hypertension. An intention-to-treat analysis will be performed for all randomised subjects receiving the study drug. The total dose of norepinephrine will be compared between the two arms by a one-tailed Mann-Whitney U test.

Ethics and dissemination

The trial protocol was approved by the local Institutional Review Board (#20–30948). Results will be posted on ClinicalTrials.gov and published in a peer-reviewed journal.

Perceptions of conflicting information about long-term medications: a qualitative in-depth interview study of patients with chronic diseases in the Swiss ambulatory care system

Por: Santos · B. · Blondon · K. S. · Sottas · M. · Carpenter · D. · Backes · C. · Van Gessel · E. · Schneider · M. P.
Objective

Patients with multiple long-term conditions visit various healthcare professionals and are exposed to medication information from various sources causing an increased risk of patients perceiving contradictory medication information. The aims of this study are to: (1) characterise conflicting medication information perceived by patients with long-term conditions, (2) better understand the related impact on patients’ medication self-management and healthcare system navigation and (3) explore ways in which such events could be prevented.

Design

This study was conducted through qualitative semistructured interviews. Data were analysed using thematic analysis.

Setting

Community pharmacies and medical centres in Geneva, Switzerland.

Participants

This study included outpatients from April 2019 to February 2020. Patients were included after participating in a quantitative survey of perceived conflicting information about medications for long-term diseases.

Methods

Semistructured audiotaped interviews of 20 to 60 min following a pre-established interview guide to explore participants’ perceptions of conflicting information. Interviews were transcribed verbatim, and a thematic analysis was conducted with inductive and deductive coding using MAXQDA (2018, Release 18.2.3).

Results

Twenty-two patients were interviewed, until data saturation, mentioning indication or need for a medication as the main topic of conflicting information between two healthcare professionals. Perceived conflicting information often resulted from insufficient information provided and poor communication leading to confusion, doubts and medication non-adherence. Patients expected more information and more interprofessional communication on their medications. As a result of conflicting information, most participants learnt or were learning to take an active role and become partners of the healthcare providers.

Conclusion

The need to strengthen and improve communication and interprofessional collaborative practice among healthcare professionals and with the patient is emerging to increase the quality and consistency of information about medications, and consequently, to ensure better use and experience of medications.
