Prescriber decision-making on antithrombotic therapy after endovascular intervention for peripheral artery disease: a protocol for a discrete choice experiment

Por: Zhu · A. · Tang · R. · Rajendran · S. · Hajian · H. · Aitken · S. J.
Introduction

Peripheral artery disease (PAD) is a major risk factor for cardiovascular morbidity and mortality, despite surgical and endovascular treatments. Emerging evidence supports the use of immediate antithrombotic medications after endovascular intervention for PAD, however, there is a lack of consensus regarding choice and duration of antithrombotic therapy. Prescriber decision-making is a complex process, with prior studies demonstrating patient factors can influence variability in antithrombotic therapy for PAD. However, it remains unclear the relative contribution of these factors. This paper describes a planned study that aims to (1) determine the influence of patient factors on clinician preference for antithrombotic therapy following endovascular intervention and (2) compare differences in prescribing preferences between consultant vascular surgeons and trainees.

Methods and analysis

This cross-sectional survey will evaluate antithrombotic prescribing choices using a discrete choice experiment (DCE) that has been developed and piloted for this study. A list of attributes and levels was generated using a mixed-methods approach. This included an extensive literature review and semistructured interviews with prescribing clinicians. Following final selection of included attributes, specialised software was used to construct a D-efficient design for the DCE questionnaire. The electronic questionnaire will be administered to vascular trainees and consultant surgeons across Australia. These data will be analysed using multinomial logistic regression, treating the decision to prescribe antithrombotic therapy as a function of both the attributes of the two alternatives, as well as characteristics of the respondent. Latent class analysis will be used to explore heterogeneity of responses.

Ethics and dissemination

Ethics approval was obtained from the University of Sydney Human Ethics committee (2023/474). The results of this study will be published in peer-reviewed journals and presented at national vascular surgical conferences. These results will be used to improve understanding how clinicians make prescribing decisions and to inform future strategy to enhance guideline-directed prescribing.

Symptomatic presentation of cancer in primary care: a scoping review of patients experiences and needs during the cancer diagnostic pathway

Por: Wheelwright · S. J. · Russ · S. · Mold · F. · Armes · J. · Harder · H.
Objectives

The objective was to map the experiences and needs of patients presenting with symptoms of suspected cancer in the primary care interval (from when they first present to primary care to their first appointment or referral to a secondary or tertiary level healthcare facility).

Design

This was a scoping review.

Inclusion criteria

Studies or reports written in English which included primary data on the primary care interval experiences and/or needs of adult patients presenting with new symptoms of suspected cancer were eligible. Studies which only included patients with secondary or recurring cancer, conference abstracts and reviews were excluded. No date limits were applied.

Methods

The Joanna Briggs Institute method for Scoping Reviews guided screening, report selection and data extraction. At least two independent reviewers contributed to each stage. Medline, CINAHL, PsychInfo, Embase and Web of Science were searched and several grey literature resources. Relevant quantitative findings were qualitised and integrated with qualitative findings. A thematic analysis was carried out.

Results

Of the 4855 records identified in the database search, 18 were included in the review, along with 13 identified from other sources. The 31 included studies were published between 2002 and 2023 and most (n=17) were conducted in the UK. Twenty subthemes across four themes (patient experience, interpersonal, healthcare professional (HCP) skills, organisational) were identified. No studies included patient-reported outcome measures. Patients wanted (1) to feel heard and understood by HCPs, (2) a plan to establish what was causing their symptoms, and (3) information about the next stages of the diagnostic process.

Conclusions

Scoping review findings can contribute to service planning as the cancer diagnostic pathway for symptomatic presentation of cancer evolves. The effectiveness of this pathway should be evaluated not only in terms of clinical outcomes, but also patient-reported outcomes and experience, along with the perspectives of primary care HCPs.

Feasibility study of a multimodal prehabilitation programme in women receiving neoadjuvant therapy for breast cancer in a major cancer hospital: a protocol

Por: Grant · S. J. · Kay · S. · Lacey · J. · Kumar · S. · Kerin-Ayres · K. · Stehn · J. · Gonzalez · M. · Templeton · S. · Heller · G. · Cockburn · J. · Wahlroos · S. · Malalasekera · A. · Mak · C. · Graham · S.
Introduction

Neoadjuvant therapy has become a standard treatment for patients with stage II/III HER2 positive and triple negative breast cancer, and in well-selected patients with locally advanced and borderline resectable high risk, luminal B breast cancer. Side effects of neoadjuvant therapy, such as fatigue, cardiotoxicity, neurotoxicity, anxiety, insomnia, vasomotor symptoms, gastrointestinal disturbance as well as a raft of immune-related adverse events, may impact treatment tolerance, long-term outcomes, and quality of life. Providing early supportive care prior to surgery (typically termed ‘prehabilitation’) may mitigate these side effects and improve quality of life.

During our codesign of the intervention, consumers and healthcare professionals expressed desire for a programme that ‘packaged’ care, was easy to access, and was embedded in their care pathway. We hypothesise that a multimodal supportive care programme including exercise and complementary therapies, underpinned by behavioural change theory will improve self-efficacy, quality of life, readiness for surgery and any additional treatment for women with breast cancer. We seek to explore cardiometabolic, residual cancer burden and surgical outcomes, along with chemotherapy completion (relative dose intensity). This article describes the protocol for a feasibility study of a multimodal prehabilitation programme.

Methods and analysis

This is a prospective, mixed-method, feasibility study of a multi-modal programme in a hospital setting for 20–30 women with breast cancer receiving neoadjuvant therapy. Primary outcomes are recruitment rate, retention rate, adherence and acceptability. Secondary outcomes include patient reported outcome measures (PROMs), surgical outcomes, length of stay, satisfaction with surgery, chemotherapy completion rates, changes in metabolic markers and adverse events. Interviews and focus groups to understand the experience with prehabilitation and different factors that may affect feasibility of the intervention . The output of this study will be a codesigned, evidence-informed intervention assessed for feasibility and acceptability by women with breast cancer and the healthcare professionals that care for them.

Ethics and dissemination

The study received ethics approval from the St Vincents Hospital HREC (HREC/2021/ETH12198). Trial results will be communicated to participants, healthcare professionals, and the public via publication and conferences.

Randomised trials conducted using cohorts: a scoping review

Por: Nickolls · B. J. · Relton · C. · Hemkens · L. · Zwarenstein · M. · Eldridge · S. · McCall · S. J. · Griffin · X. L. · Sohanpal · R. · Verkooijen · H. M. · Maguire · J. L. · McCord · K. A.
Introduction

Cohort studies generate and collect longitudinal data for a variety of research purposes. Randomised controlled trials (RCTs) increasingly use cohort studies as data infrastructures to help identify and recruit trial participants and assess outcomes.

Objective

To examine the extent, range and nature of research using cohorts for RCTs and describe the varied definitions and conceptual boundaries for RCTs using cohorts.

Design

Scoping review.

Data sources

Searches were undertaken in January 2021 in MEDLINE (Ovid) and EBM Reviews—Cochrane Methodology Registry (Final issue, third Quarter 2012).

Eligibility criteria

Reports published between January 2007 and December 2021 of (a) cohorts used or planned to be used, to conduct RCTs, or (b) RCTs which use cohorts to recruit participants and/or collect trial outcomes, or (c) methodological studies discussing the use of cohorts for RCTs.

Data extraction and synthesis

Data were extracted on the condition being studied, age group, setting, country/continent, intervention(s) and comparators planned or received, unit of randomisation, timing of randomisation, approach to informed consent, study design and terminology.

Results

A total of 175 full-text articles were assessed for eligibility. We identified 61 protocols, 9 descriptions of stand-alone cohorts intended to be used for future RCTs, 39 RCTs using cohorts and 34 methodological papers.

The use and scope of this approach is growing. The thematics of study are far-ranging, including population health, oncology, mental and behavioural disorders, and musculoskeletal conditions.

Authors reported that this approach can lead to more efficient recruitment, more representative samples, and lessen disappointment bias and crossovers.

Conclusion

This review outlines the development of cohorts to conduct RCTs including the range of use and innovative changes and adaptations. Inconsistencies in the use of terminology and concepts are highlighted. Guidance now needs to be developed to support the design and reporting of RCTs conducted using cohorts.

Feasibility of quality indicators on prehospital advanced airway management in a physician-staffed emergency medical service: survey-based assessment of the provider point of view

Por: Kottmann · A. · Pasquier · M. · Carron · P.-N. · Maudet · L. · Rouve · J.-D. · Suppan · L. · Caillet-Bois · D. · Riva · T. · Albrecht · R. · Krüger · A. · Sollid · S. J. M.
Objective

We aimed to determine the feasibility of quality indicators (QIs) for prehospital advanced airway management (PAAM) from a provider point of view.

Design

The study is a survey based feasibility assessment following field testing of QIs for PAAM.

Setting

The study was performed in two physician staffed emergency medical services in Switzerland.

Participants

42 of the 44 emergency physicians who completed at least one case report form (CRF) dedicated to the collection of the QIs on PAAM between 1 January 2019 and 31 December 2021 participated in the study.

Intervention

The data required to calculate the 17 QIs was systematically collected through a dedicated electronic CRF.

Primary and secondary outcome measures

Primary outcomes were provider-related feasibility criteria: relevance and acceptance of the QIs, as well as reliability of the data collection. Secondary outcomes were effort to collect specific data and to complete the CRF.

Results

Over the study period, 470 CRFs were completed, with a median of 11 per physician (IQR 4–17; range 1–48). The median time to complete the CRF was 7 min (IQR 3–16) and was considered reasonable by 95% of the physicians. Overall, 75% of the physicians assessed the set of QIs to be relevant, and 74% accepted that the set of QIs assessed the quality of PAAM. The reliability of data collection was rated as good or excellent for each of the 17 QIs, with the lowest rated for the following 3 QIs: duration of preoxygenation, duration of laryngoscopy and occurrence of desaturation during laryngoscopy.

Conclusions

Collection of QIs on PAAM appears feasible. Electronic medical records and technological solutions facilitating automatic collection of vital parameters and timing during the procedure could improve the reliability of data collection for some QIs. Studies in other services are needed to determine the external validity of our results.

'That gave me a lot of comfort, that he would ask my opinion about how we wanted to talk about this: A qualitative analysis of clinical communication experiences of ostomy patients

Por: Lazenby · B. S. · Guidry · A. · Donovan · E. E. · Dailey · R. · Ivatury · S. J.
Objectives

The purpose of this study was to investigate the communication challenges and successes that people with ostomies experienced during their healthcare encounters.

Design

We conducted semistructured interviews of people with ostomies. Interviews focused on important social situations and health communication strategies for managing these situations. We transcribed interviews and coded them to create themes.

Participants

Participants were eligible to participate if they were above the age of 18 and have had an ostomy for at least a year. 27 people participated in the study.

Setting

The study was conducted in a university setting.

Results

Interviews with ostomates surfaced several themes related to ostomate needs. Participants benefited from communication that was open, thorough and had a positive outlook on ostomies. Participants found patient–clinician communication to be challenging when there was a lack of knowledge surrounding ostomy care, communication was unclear or inadequate, and when clinicians had a negative outlook on ostomies.

Conclusions

Findings from this project are intended to amplify existing patient and clinician education materials and to inform the creation of a communication guide specifically for the ostomy context.

Fibre-rich Foods to Treat Obesity and Prevent Colon Cancer trial study protocol: a randomised clinical trial of fibre-rich legumes targeting the gut microbiome, metabolome and gut transit time of overweight and obese patients with a history of noncancerou

Por: Hartman · T. J. · Christie · J. · Wilson · A. · Ziegler · T. R. · Methe · B. · Flanders · W. D. · Rolls · B. J. · Loye Eberhart · B. · Li · J. V. · Huneault · H. · Cousineau · B. · Perez · M. R. · O'Keefe · S. J. D.
Introduction

Recently published studies support the beneficial effects of consuming fibre-rich legumes, such as cooked dry beans, to improve metabolic health and reduce cancer risk. In participants with overweight/obesity and a history of colorectal polyps, the Fibre-rich Foods to Treat Obesity and Prevent Colon Cancer randomised clinical trial will test whether a high-fibre diet featuring legumes will simultaneously facilitate weight reduction and suppress colonic mucosal biomarkers of colorectal cancer (CRC).

Methods/design

This study is designed to characterise changes in (1) body weight; (2) biomarkers of insulin resistance and systemic inflammation; (3) compositional and functional profiles of the faecal microbiome and metabolome; (4) mucosal biomarkers of CRC risk and (5) gut transit. Approximately 60 overweight or obese adults with a history of noncancerous adenomatous polyps within the previous 3 years will be recruited and randomised to one of two weight-loss diets. Following a 1-week run-in, participants in the intervention arm will receive preportioned high-fibre legume-rich entrées for two meals/day in months 1–3 and one meal/day in months 4–6. In the control arm, entrées will replace legumes with lean protein sources (eg, chicken). Both groups will receive in-person and written guidance to include nutritionally balanced sides with energy intake to lose 1–2 pounds per week.

Ethics and dissemination

The National Institutes of Health fund this ongoing 5-year study through a National Cancer Institute grant (5R01CA245063) awarded to Emory University with a subaward to the University of Pittsburgh. The study protocol was approved by the Emory Institutional Review Board (IRB approval number: 00000563).

Perceptions of Australias e-cigarette regulations and recommendations for future reforms: a qualitative study of adolescents and adults

Por: Brierley · M.-E. E. · Yaw · S. J. L. · Jongenelis · M. I.
Objective

To assess public perceptions of the effectiveness of e-cigarette regulations in minimising use among adolescents and those who have never smoked. Specifically, we explored (1) perceived effectiveness of current regulations relating to e-cigarettes and (2) ideas for further regulations that could reduce use.

Design and participants

Focus groups (n=16) were conducted with Australian adolescents (14–17 years), young adults (18–24 years) and adults (25–39 years). Groups were stratified by age, gender and e-cigarette use status. Data were analysed using reflexive thematic analysis.

Setting

Focus groups were conducted in-person in two major Australian cities.

Results

Groups lacked a comprehensive understanding of e-cigarette regulations in Australia. When informed of these regulations, half of the groups considered the prescription model for nicotine e-cigarette products to be effective when enforced appropriately. Almost all groups considered access to non-nicotine products problematic. All groups suggested a range of demand reduction regulations, including plain packaging, health warnings, flavour restrictions and increased vape-free areas. Most groups (predominantly those who had never vaped) also recommended supply reduction regulations such as banning all e-cigarettes. The need for supply reduction measures to include addiction and mental health supports was discussed.

Conclusions

The regulations recommended by participants largely align with those that are to be introduced in Australia, indicating that these reforms are likely to be accepted by the public. Ensuring these reforms are complemented by formal supports for young people experiencing nicotine dependence and related mental health concerns is critical.

Qualitative interview study of strategies to support healthcare personnel mental health through an occupational health lens

Por: Brown-Johnson · C. · DeShields · C. · McCaa · M. · Connell · N. · Giannitrapani · S. N. · Thanassi · W. · Yano · E. M. · Singer · S. J. · Lorenz · K. A. · Giannitrapani · K.
Background

Employee Occupational Health (‘occupational health’) clinicians have expansive perspectives of the experience of healthcare personnel. Integrating mental health into the purview of occupational health is a newer approach that could combat historical limitations of healthcare personnel mental health programmes, which have been isolated and underused.

Objective

We aimed to document innovation and opportunities for supporting healthcare personnel mental health through occupational health clinicians. This work was part of a national qualitative needs assessment of employee occupational health clinicians during COVID-19 who were very much at the centre of organisational responses.

Design

This qualitative needs assessment included key informant interviews obtained using snowball sampling methods.

Participants

We interviewed 43 US Veterans Health Administration occupational health clinicians from 29 facilities.

Approach

This analysis focused on personnel mental health needs and opportunities, using consensus coding of interview transcripts and modified member checking.

Key results

Three major opportunities to support mental health through occupational health involved: (1) expanded mental health needs of healthcare personnel, including opportunities to support work-related concerns (eg, traumatic deployments), home-based concerns and bereavement (eg, working with chaplains); (2) leveraging expanded roles and protocols to address healthcare personnel mental health concerns, including opportunities in expanding occupational health roles, cross-disciplinary partnerships (eg, with employee assistance programmes (EAP)) and process/protocol (eg, acute suicidal ideation pathways) and (3) need for supporting occupational health clinicians’ own mental health, including opportunities to address overwork/burn-out with adequate staffing/resources.

Conclusions

Occupational health can enact strategies to support personnel mental health: to structurally sustain attention, use social cognition tools (eg, suicidality protocols or expanded job descriptions); to leverage distributed attention, enhance interdisciplinary collaboration (eg, chaplains for bereavement support or EAP) and to equip systems with resources and allow for flexibility during crises, including increased staffing.

Feasibility and acceptability of offering breast cancer risk assessment to general population women aged 30-39 years: a mixed-methods study protocol

Por: Hindmarch · S. · Howell · S. J. · Usher-Smith · J. A. · Gorman · L. · Evans · D. G. · French · D. P.
Introduction

Breast cancer incidence starts to increase exponentially when women reach 30–39 years, hence before they are eligible for breast cancer screening. The introduction of breast cancer risk assessment for this age group could lead to those at higher risk receiving benefits of earlier screening and preventive strategies. Currently, risk assessment is limited to women with a family history of breast cancer only. The Breast CANcer Risk Assessment in Younger women (BCAN-RAY) study is evaluating a comprehensive breast cancer risk assessment strategy for women aged 30–39 years incorporating a questionnaire of breast cancer risk factors, low-dose mammography to assess breast density and polygenic risk. This study will assess the feasibility and acceptability of the BCAN-RAY risk assessment strategy.

Methods and analysis

This study involves women undergoing risk assessment as part of the BCAN-RAY case-control study (n=750). They will be aged 30–39 years without a strong family history of breast cancer and invited to participate via general practice. A comparison of uptake rates by socioeconomic status and ethnicity between women who participated in the BCAN-RAY study and women who declined participation will be conducted. All participants will be asked to complete self-report questionnaires to assess key potential harms including increased state anxiety (State Trait Anxiety Inventory), cancer worry (Lerman Cancer Worry Scale) and satisfaction with the decision to participate (Decision Regret Scale), alongside potential benefits such as feeling more informed about breast cancer risk. A subsample of approximately 24 women (12 at average risk and 12 at increased risk) will additionally participate in semistructured interviews to understand the acceptability of the risk assessment strategy and identify any changes needed to it to increase uptake.

Ethics and dissemination

Ethical approval was granted by North West—Greater Manchester West Research Ethics Committee (reference: 22/NW/0268). Study results will be disseminated through peer-reviewed journals, conference presentations and charitable organisations.

Ischaemic stroke in patients with diabetes requiring urgent procedures during the COVID-19 pandemic in South Korea: a retrospective, nationwide, population-based cohort study using data from the National Emergency Department Information System

Por: Park · M. J. · Hwang · J. · Ahn · J. · Park · S. J. · Song · E. · Jang · A. · Choi · K. M. · Baik · S. H. · Yoo · H. J.
Objectives

The COVID-19 pandemic resulted in suboptimal care for ischaemic stroke. Patients with diabetes mellitus (DM), a high-risk group for stroke, had compromised routine care during the pandemic, which increases the chance of stroke. We examined influence of the COVID-19 pandemic on the management of ischaemic stroke in patients with DM in South Korea.

Design

Retrospective, nationwide, population-based cohort study.

Setting

Data from the National Emergency Department Information System.

Participants

We analysed 11 734 patients diagnosed with acute ischaemic stroke who underwent intravenous thrombolysis or endovascular thrombectomy between 2019 (the reference year) and 2020 (the pandemic year). Among them, 1014 subjects with DM were analysed separately.

Outcome measures

The frequency of emergency department (ED) visits, time from symptom onset to ED, from ED visit to admission and in-hospital mortality were compared between two periods in the overall population and in patients with DM.

Results

During the pandemic, the incidence of ischaemic stroke requiring urgent procedures increased by 7.57% in total and by 9.03% in patients with DM. Time delay from symptom onset to ED (reference vs pandemic, total: 1.50 vs 1.55 hours; p

Conclusions

During the COVID-19 pandemic, the incidence of ischaemic stroke requiring urgent procedures increased, and older patients with DM showed a higher ICU admission rate. However, the pandemic was not associated with an increased in-hospital stroke mortality.

The moderating and mediating role of eating behaviour traits in acceptance and commitment therapy-based weight management interventions: protocol for an individual participant data meta-analysis

Por: Kudlek · L. · Mueller · J. · Eustacio Colombo · P. · Sharp · S. J. · Griffin · S. J. · Ahern · A.
Introduction

Precision medicine approaches to obesity aim to maximise treatment effectiveness by matching weight management interventions (WMIs) to characteristics of individuals, such as eating behaviour traits (EBTs). Acceptance and commitment therapy (ACT)-based WMIs may address EBTs such as emotional and uncontrolled eating more effectively than standard interventions, and might be most effective in people with high levels of these traits. However, few studies have examined this directly. We will examine (a) whether ACT-based interventions are more effective for people with certain levels of EBTs (ie, moderation) and (b) whether ACT-based interventions operate through changes in EBTs (ie, mediation).

Methods and analysis

This individual participant data (IPD) meta-analysis will follow the Preferred Reporting Items for Systematic Reviews and Meta-Analyses of Individual Participant Data guidance. We will include studies on ACT-based WMIs that assessed EBTs in people with a body mass index ≥25 kg/m2. We identified studies by screening studies included in a previous review of third wave cognitive behavioural interventions, and updating the search to 20 June 2022. We will request IPD from eligible published and unpublished studies. We will harmonise and re-analyse data using a two-stage random effects meta-analysis pooling within-trial interactions to investigate moderating effects and using a one-stage simultaneous equation model to examine mediating effects. We will assess the risk of bias in included studies using the Cochrane Risk of Bias tool 2 and the Risk of Bias in Non-randomised Studies of Interventions tool.

Ethics and dissemination

Ethical approval has been obtained from the Cambridge Psychology Research Ethics Committee (Application No: PRE.2023.121). Data sharing will follow data transfer agreements and coauthorship will be offered to investigators contributing data. Findings will be disseminated through peer-reviewed journals and conferences and will contribute to the lead author’s PhD thesis.

Increasing the reach of evidence-based interventions for weight management and diabetes prevention among Medicaid patients: study protocol for a pilot Sequential Multiple Assignment Randomised Trial

Por: Schlechter · C. R. · Del Fiol · G. · Jones · D. R. · Orleans · B. · Gibson · B. · Nahum-Shani · I. · Maxfield · E. · Locke · A. · Cornia · R. · Bradshaw · R. · Wirth · J. · Jaggers · S. J. · Lam · C. Y. · Wetter · D. W.
Introduction

Over 40% of US adults meet criteria for obesity, a major risk factor for chronic disease. Obesity disproportionately impacts populations that have been historically marginalised (eg, low socioeconomic status, rural, some racial/ethnic minority groups). Evidence-based interventions (EBIs) for weight management exist but reach less than 3% of eligible individuals. The aims of this pilot randomised controlled trial are to evaluate feasibility and acceptability of dissemination strategies designed to increase reach of EBIs for weight management.

Methods and analysis

This study is a two-phase, Sequential Multiple Assignment Randomized Trial, conducted with 200 Medicaid patients. In phase 1, patients will be individually randomised to single text message (TM1) or multiple text messages (TM+). Phase 2 is based on treatment response. Patients who enrol in the EBI within 12 weeks of exposure to phase 1 (ie, responders) receive no further interventions. Patients in TM1 who do not enrol in the EBI within 12 weeks of exposure (ie, TM1 non-responders) will be randomised to either TM1-Continued (ie, no further TM) or TM1 & MAPS (ie, no further TM, up to 2 Motivation And Problem Solving (MAPS) navigation calls) over the next 12 weeks. Patients in TM+ who do not enrol in the EBI (ie, TM+ non-responders) will be randomised to either TM+Continued (ie, monthly text messages) or TM+ & MAPS (ie, monthly text messages, plus up to 2 MAPS calls) over the next 12 weeks. Descriptive statistics will be used to characterise feasibility (eg, proportion of patients eligible, contacted and enrolled in the trial) and acceptability (eg, participant opt-out, participant engagement with dissemination strategies, EBI reach (ie, the proportion of participants who enrol in EBI), adherence, effectiveness).

Ethics and dissemination

Study protocol was approved by the University of Utah Institutional Review Board (#00139694). Results will be disseminated through study partners and peer-reviewed publications.

Clinician and patient perspectives on the barriers and facilitators to physical rehabilitation in intensive care: a qualitative interview study

Por: Woodbridge · H. R. · Norton · C. · Jones · M. · Brett · S. J. · Alexander · C. M. · Gordon · A. C.
Objectives

The objective of this study is to explore patient, relative/carer and clinician perceptions of barriers to early physical rehabilitation in intensive care units (ICUs) within an associated group of hospitals in the UK and how they can be overcome.

Design

Qualitative study using semi-structured interviews and thematic framework analysis.

Setting

Four ICUs over three hospital sites in London, UK.

Participants

Former ICU patients or their relatives/carers with personal experience of ICU rehabilitation. ICU clinicians, including doctors, nurses, physiotherapists and occupational therapists, involved in the delivery of physical rehabilitation or decisions over its initiation.

Primary and secondary outcomes measures

Views and experiences on the barriers and facilitators to ICU physical rehabilitation.

Results

Interviews were carried out with 11 former patients, 3 family members and 16 clinicians. The themes generated related to: safety and physiological concerns, patient participation and engagement, clinician experience and knowledge, teamwork, equipment and environment and risks and benefits of rehabilitation in intensive care. The overarching theme for overcoming barriers was a change in working model from ICU clinicians having separate responsibilities (a multidisciplinary approach) to one where all parties have a shared aim of providing patient-centred ICU physical rehabilitation (an interdisciplinary approach).

Conclusions

The results have revealed barriers that can be modified to improve rehabilitation delivery in an ICU. Interdisciplinary working could overcome many of these barriers to optimise recovery from critical illness.

Study protocol for a longitudinal observational study of disparities in sleep and cognition in older adults: the DISCO study

Por: Knutson · K. L. · Pershing · M. L. · Abbott · S. · Alexandria · S. J. · Chiluka · S. · Chirinos · D. · Giachello · A. · Gupta · N. · Harrington · K. · Rittner · S. S. · Sorond · F. · Wong · M. · Vu · T.-H. T. · Zee · P. C. · Carnethon · M. R.
Introduction

Cognitive dysfunction, a leading cause of mortality and morbidity in the USA and globally, has been shown to disproportionately affect the socioeconomically disadvantaged and those who identify as black or Hispanic/Latinx. Poor sleep is strongly associated with the development of vascular and metabolic diseases, which correlate with cognitive dysfunction. Therefore, sleep may contribute to observed disparities in cognitive disorders. The Epidemiologic Study of Disparities in Sleep and Cognition in Older Adults (DISCO) is a longitudinal, observational cohort study that focuses on gathering data to better understand racial/ethnic sleep disparities and illuminate the relationship among sleep, race and ethnicity and changes in cognitive function. This investigation may help inform targeted interventions to minimise disparities in cognitive health among ageing adults.

Methods and analysis

The DISCO study will examine up to 495 individuals aged 55 and older at two time points over 24 months. An equal number of black, white and Hispanic/Latinx individuals will be recruited using methods aimed for adults traditionally under-represented in research. Study procedures at each time point will include cognitive tests, gait speed measurement, wrist actigraphy, a type 2 home polysomnography and a clinical examination. Participants will also complete self-identified assessments and questionnaires on cognitive ability, sleep, medication use, quality of life, sociodemographic characteristics, diet, substance use, and psychological and social health.

Ethics and dissemination

This study was approved by the Northwestern University Feinberg School of Medicine Institutional Review Board. Deidentified datasets will be shared via the BioLINCC repository following the completion of the project. Biospecimen samples from the study that are not being analysed can be made available to qualified investigators on review and approval by study investigators. Requests that do not lead to participant burden or that conflict with the primary aims of the study will be reviewed by the study investigators.
