To characterise long-term trajectory of recovery in individuals with long covid.

Prospective cohort.

Single-centre, specialist post-COVID service (London, UK).

Individuals aged ≥18 years with long covid (hospitalised and non-hospitalised) from April 2020 to March 2024.

Routine, prospectively collected data on symptoms, quality of life (including Fatigue Assessment Scale (FAS) and EuroQol 5 Dimensions (EQ-5D), return to work status and healthcare utilisation (investigations, outpatient and emergency attendances). The primary outcome was recovery by self-reported >75% of ‘best health’ (EQ-5D Visual Analogue Scale) and was assessed using Cox proportional hazards regression models over 4 years. Linked National Health Service England registry data provided secondary care healthcare utilisation and expenditure.

We included 3590 individuals (63.3% female, 73.5% non-hospitalised, median age 50.0 years, 71.9% with ≥2 doses of COVID-19 vaccination), who were followed up for a median of 136 (0–346) days since first assessment and 502 (251–825) days since symptom onset. At first assessment, 33.2% of employed individuals were unable to work. Dominant symptoms were fatigue (78.7%), breathlessness (68.1%) and brain fog (53.5%). 33.4% of individuals recovered to >75% of best health prior to clinic discharge (recovery occurred median 202 (94–468) days from symptom onset). Vaccinated individuals were more likely to recover faster (pre: HR 2.93 (2.00–4.28) and post: HR 1.34 (1.05–1.71) COVID-19 infection), whereas recovery hazard was inversely associated with FAS (HR 0.37 (0.33–0.42)), myalgia (HR 0.59 (0.45–0.76)) and dysautonomic symptoms (HR 0.46 (0.34–0.62)). There was high secondary care healthcare utilisation (both emergency and outpatient care). Annual inpatient and outpatient expenditure was significantly lower in hospitalised individuals while under the service. When compared with the prereferral period, emergency department attendances were reduced in non-hospitalised patients with long covid, but outpatient costs increased.

In the largest long covid cohort from a single specialist post-COVID service to date, only one-third of individuals under follow-up achieved satisfactory recovery. Fatigue severity and COVID-19 vaccination at presentation, even after initial COVID-19 infection, was associated with long covid recovery. Ongoing service provision for this and other post-viral conditions is necessary to support care, progress treatment options and provide capacity for future pandemic preparedness. Research and clinical services should emphasise these factors as the strongest predictors of non-recovery.

Studies have demonstrated the positive impact of falls prevention interventions for high-risk older adults who have experienced a severe fall. However, uptake and adherence rates remain low. The purpose of this study is to assess the capabilities, opportunities and motivations of older adults following a fall with subsequent presentation to the emergency department and direct discharge home in relation to falls prevention measures.

This study, conducted as part of the ‘Sentinel fall presenting to the emergency department’ project at the Carl von Ossietzky University Oldenburg in Germany, involved a participatory research team (PRT). It was a qualitative study based on focus group interviews undertaken between June and October 2022, analysed in accordance with qualitative content analysis following Kuckartz. The Theoretical Domains Framework forms the basis of the deductive category system. PRT members collaborated as co-researchers in conducting and analysing the focus groups.

12 focus groups were conducted (N=52). The participants were older adults (≥60 years) who had received outpatient care in an emergency department following a fall (N=41) and their relatives (N=11).

Interviewees indicated that both knowledge of available support options and the ability to self-evaluate are important following a fall. Additionally, health circumstances, such as limitations resulting from fall-related consequences, influence the adoption of falls prevention measures. Social influences, as well as environmental context and resources, were also discussed, reflecting participants’ preferences for intervention design, such as having a central point of contact and specific courses on fall training. Moreover, the fall event itself may strengthen the perceived need for preventive measures, whereas a fear of falling can lead to reduced or modified activity levels.

To improve the engagement of older adults in falls prevention interventions following a fall, the establishment of a central point of contact could be considered. Individual tailored interventions, including psychological support as well as specific fall training, are needed.

To understand how reductions in resource allocation affect food safety services in England.

This longitudinal ecological study analysed secondary observational data.

England, data at the local authority level.

Ecological study, without human participants.

The primary outcome measures were the number of staff, represented by the number of full-time equivalents per capita, number of interventions per establishment, and proportion of hygiene-compliant establishments.

A £1 decrease in food safety expenditure per capita was associated with a 2% (–3.3 to –0.7) decrease in staffing levels and a 1.6% (–3.2 to –0.1) decrease in the number of interventions achieved per establishment. A one-unit reduction in staff was associated with a 42.2% (–80.5 to –11.9) decrease in the number of interventions achieved. No evidence of an association was found between expenditure or staff levels and the proportion of compliant establishments.

Spending reductions negatively affected the capacity of food safety teams to provide key services. Reductions in food safety expenditure significantly affected food hygiene staff levels and service provision. This finding raises concerns about the capacity of food safety teams to operate and the potential for increased public risk of gastrointestinal infections.

To compare primary care for depression among patients detected in the first 21 months of the SARS-CoV-2 pandemic to patients detected pre-pandemic, and examine whether depression care was associated with patient characteristics.

Retrospective pre–post study using de-identified data from electronic medical record data from the Canadian Primary Care Sentinel Surveillance Network (CPCSSN).

Primary care clinics enrolled in CPCSSN from 1 January 2018 to 31 December 2021.

Patients with a valid CPCSSN case definition of depression detected between 01 January 2018 and 31 December 2021 were included in the cohort and categorised by detection date (pre-pandemic or during Canadian pandemic waves).

Primary care encounters, psychotropic prescriptions and selective serotonin reuptake inhibitor (SSRI) prescriptions were observed at 3 and 12 months post-detection. Multivariable regression evaluated associations between patients’ depression detection timing and depression care, adjusting for age, sex, rurality, neighbourhood deprivation quintile, province, number of observable comorbidities and pre-detection psychotropic use.

91 453 patients with depression were identified, of whom 53% were detected pre-pandemic. Patients detected during the pandemic were younger and less comorbid than those detected pre-pandemic. Proportions of patients with any encounter, psychotropic prescriptions and SSRI prescriptions were higher for patients detected during every pandemic wave compared with patients detected pre-pandemic. The adjusted incidence rate ratios (aIRRs) of number of encounters (aIRR=1.15; 95% CI 1.13 to 1.17), psychotropics (aIRR=1.11, 95% CI 1.09 to 1.13) and SSRIs prescribed (aIRR=1.12; 95% CI 1.10 to 1.15) within 3 months of detection were higher among patients detected during the first pandemic wave compared with those detected pre-pandemic. Socio-demographic characteristics had weaker associations with outcomes compared with timing of detection. Results were similar within 12 months of detection.

Overall, primary care for depression was maintained during the pandemic despite challenging circumstances. Increases in paediatric encounter rates and increased prescribing in younger adults warrant further investigation to understand the factors driving these patterns.

Tourette syndrome is a common, disabling childhood-onset condition. Exposure and response prevention (ERP) is an effective treatment for tics, yet access remains limited due to a shortage of trained therapists and uneven geographical distribution of services. The ORBIT trial demonstrated that internet-delivered ERP is both clinically and cost-effective, but was developed on a university research platform, not suitable for widescale roll-out. To enable adoption by the National Health Service (NHS) in England, ORBIT has been redeveloped on an NHS compliant platform. This study will evaluate the usability, acceptability and preliminary outcomes of ORBIT on the new platform within an NHS tic disorder service.

This single-cohort usability study will recruit 20 children and young people (aged 9–17) with tics and their chosen supporters (parents/carers). Participants will receive a 10-week online ERP intervention supported by trained coaches. Outcomes include uptake, adherence, system usability, satisfaction and clinical measures such as the Yale Global Tic Severity Scale, Parent Tic Questionnaire and Goal-Based Outcomes. Qualitative feedback will be collected via semi-structured exit interviews. Usability metrics and adverse events will be monitored throughout.

The study has received ethical approval from North West Greater Manchester Research Ethics Committee (ref: 25/NW/0107). The findings from the study will inform future NHS adoption. The results will be submitted for publication in peer-reviewed journals.

Older adults can have difficulties understanding and recalling information prior to hospitalisation for elective treatment. Limited research exists regarding how older adults perceive the accessibility and comprehensibility of the information provided by the hospital prior to elective hospitalisation. This study aims to explore how older adults undergoing elective hospitalisation for transcatheter aortic valve implantation (TAVI) experience the information received from the hospital and their preferences for modes of information delivery.

A qualitative design was used. Data were collected through individual semistructured interviews with older adults prior to hospital discharge following elective TAVI. The data were analysed using reflective thematic analysis.

All patients scheduled for elective hospitalisation for TAVI at a public university hospital in Norway were screened for eligibility.

18 older adults participated in the study. Their median age was 82 years (range 67–91), and two thirds were males.

The data were categorised into four main themes: ‘The paper brochure is worth its weight in gold’, ‘Combination of different modes of information delivery increased understanding and recall’, ‘Trust reduced the need to access and understand information’ and ‘Family played a crucial role in accessing and interpreting health information’.

Older adults undergoing elective hospitalisation found the traditional brochure valuable, alone or in combination with the digital material, which included an animated film. The participants emphasised that support from family members was required to access the digital information.

Application of artificial intelligence (AI) tools in the healthcare setting gains importance especially in the domain of disease diagnosis. Numerous studies have tried to explore AI in the diagnosis of various diseases, including tropical fevers such as dengue and malaria. However, there is a lack of standard guidelines to develop the AI models, the gap between clinical and engineering expertise and clinical validation of the models, and hence there is a critical need for the development of an integrated diagnostic tool which uses demographical, laboratory variables and epidemiological parameters of patient and provides early prediction.

The present study aimed to develop and evaluate a machine-learning (ML) prediction tool for differential diagnosis of tropical fevers for adult patients (>18 years) using a three-phase approach in a tertiary care centre in South India by January 2026. Phase involves identification of the prevalent tropical fevers and associated clinical parameters to develop the AI model through a retrospective audit and qualitative interview. Phase Ⅱ involves retrospective data collection from hospital medical records for finalised diseases (1000 cases per disease) and clinical parameters, with data being used for model development using the Python language. Support vector machine, logistic regression, K-Nearest Neighbors, Naïve Bayes and ensemble models such as decision tree and Random Forest will be employed along with explainable AI techniques. They are used as they are easy to understand and interpret, well established, most effective for structured data, enhancing the transparency and interpretability of the predictive machine learning models, and their use has been widely supported in previous studies across various contexts. Suitable statistical parameters like specificity, sensitivity and area under receiver operating characteristic (AUROC) will be applied to evaluate model performance. In phase , the developed model will be implemented prospectively to assess the feasibility of model implementation. Model performance such as specificity, sensitivity and AUROC will be calculated, and the finally developed model will be implemented in a single tertiary care hospital to evaluate its overall performance.

Ethical approval for the study has been obtained from the institutional ethics committee of the Kasturba Medical College and Kasturba Hospital, Manipal (IEC number: 6/2024). Informed consent will be taken for obtaining the data of the patient for the evaluation of the model in the third phase of the study, and data will be kept confidential. The study results will be disseminated by publishing them in a peer-reviewed journal.

The protocol has been registered with the Clinical Trial Registry of India (CTRI) (CTRI/2024/04/065866) and approved on 16 April 2024.

Major haemorrhage is the leading cause of preventable death in trauma, and prehospital blood transfusion may improve survival and outcomes for patients with prolonged out-of-hospital times. Globally, there is increasing interest in the use of whole blood in the prehospital environment, with randomised controlled trials ongoing. However, the results of these studies may not be generalisable to the longer out-of-hospital times seen in the Canadian trauma environment. The aim of this trial is to determine the feasibility of performing a randomised clinical trial evaluating the use of leukocyte-reduced whole blood transfusion compared with component blood transfusion in the Canadian prehospital environment. The secondary objective is to explore whether whole blood transfusion is better in reducing the proportion of patients who die or require massive transfusion within 24 hours.

This is a multi-centre, open-label, randomised controlled feasibility trial. Patients aged 16 years or older will be eligible if they have suffered a major traumatic haemorrhage, are attended by the provincial air ambulance service and require a prehospital blood transfusion. The primary outcome is feasibility as measured by the following metrics: proportion of patients enrolled with full data collection, proportion of patients who received at least one prehospital transfusion prior to arriving at the receiving trauma centre, proportion of patients who completed transfusion of all assigned blood units, number of patients unable to be enrolled due to lack of whole blood availability and number of whole blood units produced for the study that were wasted or expired. The secondary outcome is a composite outcome of death (all-cause mortality) or receipt of massive transfusion (receipt of 10 units of blood or more) within the first 24 hours from randomisation. We plan to recruit 60 patients, with an anticipated post-randomisation exclusion of ~10 patients for traumatic cardiac arrest or who do not meet eligibility criteria.

Provincial ethics approval was obtained (Clinical Trials Ontario REB ID: CTO-4921). An opt-out consent model will be employed for participants. The SWiFT Canada trial will recruit 60 patients through the provincial air ambulance organisation in Ontario who are transported to one of the six participating lead trauma centres. It will investigate the feasibility of a pre-hospital transfusion clinical trial in Canada to compare the effectiveness of whole blood compared with component blood therapy in a future definitive trial.

To characterise the reporting practices of sequential multiple assignment randomised trials (SMARTs) in human health research.

Scoping review of protocol and primary analysis papers describing SMARTs published between January 2009 and February 2024.

SMARTs are innovative trial designs that allow for multiple stages of randomisation to treatment, with randomization potentially based on a patient’s response(s) to previous treatment(s). They are uniquely designed to develop sequential adaptive interventions (dynamic treatment regimes (DTRs)) to support personalized clinical decision-making over time. Previous reviews have identified inconsistencies in how the design, implementation and results of SMARTs have been reported in published studies. A comprehensive assessment of SMART reporting practices is lacking and necessary for developing standardised SMART-specific reporting guidelines.

We systematically searched multiple databases for SMART-related protocol and primary analysis papers published between January 2009 and February 2024. Title, abstract and full-text screenings were performed by pairs of reviewers, with disagreements resolved by consensus. Data extraction included study characteristics, design elements and analytical approaches for embedded or tailored DTRs. Results were synthesised qualitatively and presented descriptively.

From 5486 screened studies, 103 (59 protocol papers, 16 primary analysis papers, 14 protocol papers with corresponding primary analysis papers) met the inclusion criteria. Most studies targeted adults (62.7% protocols, 62.5% primary analyses, 42.9% protocol+primary analyses) and were primarily conducted in the USA. Behavioural and mental health constituted the most frequent therapeutic domain. While intervention descriptions and re-randomisation criteria were consistently reported, operational characteristics such as blinding (protocols: 64.4%, primary analyses: 62.5%, protocols+primary analyses: 71.4%) and randomisation details (protocols: 55.9%, primary analyses: 37.5%, protocols+primary analyses: 50.0%) were inconsistently documented. Only 46.7% of primary analyses evaluated embedded DTRs, and none explored deeply tailored DTRs.

Despite the increased adoption of SMART designs, substantial reporting variability persists. Most primary analyses underuse the capability of SMARTs to generate data for developing DTRs. SMART-specific standardised reporting guidelines can help accelerate the scientific and clinical impact of SMARTs.

Retroperitoneal sarcomas (RPS) are rare and often large malignancies that frequently require extensive surgery for complete tumour removal. Resections of the colorectum are part of the standard resection, this way contributing to complication rates, including anastomotic leakage or obstruction. Surgical strategies for stoma formation and colorectal reconstruction remain poorly defined. The Colorectal Resections and Postoperative Quality of Life in Retroperitoneal Sarcoma Patients Across German-Speaking Sarcoma Centres (COLOSARC-Q) study aims to explore surgical procedures and health-related quality of life (HRQoL) in patients undergoing colorectal procedures during RPS surgery.

COLOSARC-Q is a prospective, multicentre, non-interventional study and will recruit 120 patients with primary RPS who undergo colorectal resection as part of sarcoma surgery in a sarcoma referral centre in Germany or Switzerland. HRQoL is assessed using standardised questionnaires (EORTC QLQ-C30, QLQ-CR29) as well as semi-structured interviews by psycho-oncology services and patient advocates. Data will be collected via an electronic Case Report Form, encompassing demographic, clinical, surgical and outcome-related information. All data will be centrally analysed. For the assessment of quality of life, a qualitative analysis with content and context analysis, as well as evaluation of the questionnaires according to a standardised scoring system, is planned. The primary aim is to evaluate surgical techniques for bowel resection and reconstruction and their influence on the further course of disease. Secondary endpoints assess postoperative complications as well as tumour-, patient- and treatment-related factors.

Ethical approval was granted by the Ethics Committee II of the University of Heidelberg (approval number 2024-562; 13 June 2024). The data protection review was approved by the data protection officer of the University of Heidelberg. Participation of other centres in the study requires local ethical approval. All patients will be required to sign an informed consent form. Results of primary and secondary endpoints will be published.

To understand how key relational factors lead to observed outcomes in mental health peer support.

This realist-informed qualitative review synthesised findings from 18 studies to develop programme theory relating to interpersonal contexts, linked outcomes and underlying mechanisms of change of mental health peer support.

Four databases were searched: PsycINFO, Embase, Medline, CINAHL.

All studies were evaluated for relevance and rigour for development of programme theory.

Qualitative data were extracted from 20 studies. A realist-informed synthesis identified repeating themes with context-mechanism-outcome configurations.

This identified five key contextual factors that together form the APPEAR framework (Accepting, Personalised Practice, Empowering, Available and Reciprocal). These contextual factors were found to interact to create the conditions for improved personal recovery outcomes in the domains of (1) self-acceptance, (2) confidence, (3) hopefulness, (4) self-expression, (5) relationships and (6) knowledge and skills.

The APPEAR framework offers an operational foundation for understanding interpersonal mental health peer support interventions.

Metabolic dysfunction-associated steatotic liver disease (MASLD) and gestational diabetes mellitus (GDM) are prevalent metabolic disorders in pregnancy, posing significant risks to maternal and fetal health. This study evaluates the effectiveness of metformin, in combination with lifestyle modifications, compared with lifestyle modifications alone, in reducing the incidence of diabetes, pro-inflammatory liver markers, adverse maternal and neonatal outcomes and total gestational weight gain in pregnant women diagnosed with MASLD in the first trimester.

This parallel-arm, randomised controlled trial will recruit pregnant women (≤14 weeks of gestation) with confirmed MASLD from antenatal clinics of tertiary care public hospitals in Puducherry, India. Participants will be consecutively enrolled until a sample size of 296 is reached. Block randomisation will ensure balanced group allocation, with allocation concealment maintained using sequentially numbered opaque sealed envelopes. The intervention group will receive oral metformin (500 mg two times per day) alongside structured lifestyle modification counselling, while the control group will receive lifestyle modification counselling alone. Primary outcomes include GDM incidence, changes in pro-inflammatory markers, MASLD grading (assessed via liver function tests and ultrasound) and adverse maternal outcomes such as hypertensive disorders, polyhydramnios, genitourinary infections, caesarean delivery and postpartum haemorrhage. Neonatal outcomes assessed include macrosomia, stillbirth, intrauterine death, birth injury, shoulder dystocia, respiratory distress and neonatal hypoglycaemia. The secondary outcome is total gestational weight gain. Participants will be followed at 24–28 weeks, 34–36 weeks and post partum (within 6 weeks of delivery). Data collection will be conducted using a pretested structured questionnaire, with data entry and management performed using REDCap software. Statistical analysis will be conducted using STATA V.4, applying both intention-to-treat and per-protocol analyses. Effect sizes will be reported as proportions and relative risks with 95% CIs, ensuring robust statistical inference.

This study provides a rigorous framework to assess metformin’s role in managing MASLD and preventing GDM, thereby promoting favourable maternal and neonatal outcomes. Findings will contribute to improved clinical management, public health strategies and policy recommendations.

The study was approved by the JIPMER Institutional Ethics Committee (JIP/AEC/2023/01/011), and the findings will be disseminated through peer-reviewed journals and academic conferences.

Pain in patients with rheumatoid arthritis (RA) is an unmet clinical need. Targeting joint inflammation with disease-modifying antirheumatic drugs has not resulted in the anticipated reduction in pain for many patients. This can partly be explained by the concept of central sensitisation whereby spinal and supraspinal pathways have a lower threshold of activation, leading to increased perception of pain. Synovial stromal cells, such as fibroblasts, are also thought to play a role through peripheral sensitisation of nerves in the joint. Synovial fibroblasts are known to produce pro-algesic mediators such as interleukin 6 and nerve growth factor at the messenger RNA level. These pro-algesic mediators could activate sensory nerve fibres that send signals from the joint to the spinal cord, thereby driving persistent pain in RA. The purpose of this study is to evaluate which pro-algesic mediators are produced by lining versus sub-lining fibroblasts and whether the level of these mediators correlates with clinical measures of pain in patients with RA.

FiND-Pain RA is a multicentre observational study which will recruit 50 patients with seropositive RA who attend the rheumatology department of Guy’s and St Thomas’ Hospital, London, and the Nuffield Orthopaedic Centre, Oxford. Clinical examination, pain-focused patient-reported outcome measures, ultrasound examination and ultrasound-guided synovial biopsy of the knee will be performed. The levels of known and putative pro-algesic mediators will be measured in fibroblasts from the lining and sub-lining layer of the synovium. The location and spatial morphology of sensory nerve fibres and their proximity to lining and sub-lining fibroblasts will be characterised. The primary outcome will be to determine whether the knee pain scores of participants correlate with the level of leukaemia inhibitory factor, a novel putative pain-mediator expressed in sub-lining fibroblasts. The secondary outcomes will be to determine whether other pro-algesic mediators produced by lining or sub-lining fibroblasts correlate with clinical measures of pain and to assess the location and proximity of sensory nerve fibres to lining versus sub-lining fibroblasts.

The study is a sub-study of the PUMIA (Pain Phenotypes and their Underlying Mechanisms in Inflammatory Arthritis) study, which has been approved by the Bromley Research Ethics Committee (REC: 21/LO/0712). The findings of this study will be disseminated through open-access publications, as well as scientific and clinical conferences.

To explore barriers and facilitators to a good death in patients with respiratory disease when advanced respiratory support, including non-invasive ventilation (NIV) and continuous positive airway pressure (CPAP), is used. Specifically, we examined healthcare professionals’ perspectives on what constitutes a good death in this context, how treatment failure is recognised, how decisions to continue or withdraw therapy are made, and the impact of providing this care on staff.

Qualitative study using semistructured interviews and reflexive thematic analysis.

Secondary care services in a large UK National Health Service Trust, including acute medicine, general medicine, respiratory medicine and palliative care.

25 healthcare professionals (19 female, 6 male) from multidisciplinary backgrounds, including doctors, nurses and physiotherapists. Participants self-identified as experienced in the provision of NIV/CPAP at the end of life. Staff working primarily in intensive care units were excluded.

None.

Not applicable.

Healthcare professionals described the complexity of caring for patients dying while receiving or recently withdrawn from NIV/CPAP. Five interrelated themes were identified: beliefs around dying well, symptom management during active treatment, recognition of treatment failure, negotiated decision-making and the process of withdrawal. Staff reported tensions between providing active treatment and ensuring comfort, inconsistent practices regarding symptom control and withdrawal, and conflicts within multidisciplinary teams. Nurses highlighted hidden psychological and relational labour in supporting patients, while doctors often described delays in decision-making to align families with treatment withdrawal.

Caring for patients using NIV/CPAP at the end of life presents ethical, clinical and emotional challenges for staff, patients and families. Variation in practices and perspectives highlights the need for structured training, interdisciplinary approaches and greater recognition of the often hidden relational and emotional labour involved in this work, particularly among nursing colleagues. Further research should evaluate strategies to support consistent and compassionate withdrawal practices.

The global population of older adults has grown at an unprecedented rate, and projections indicate that the number of older adults will continue to increase considerably in the coming decades. The clinical complexity of older adults living in retirement homes, also known as assisted living settings, is also increasing, and the regulations to ensure quality and safety standards in retirement homes are highly variable. The purpose of this scoping review is to map and summarise the methods used to monitor and measure the safety of older adults living in retirement homes, providing an overview of existing approaches and areas requiring further investigation.

This scoping review will follow the five stages of the Arksey and O’Malley scoping review process. We will report this review using the Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews. A comprehensive search of four electronic databases (MEDLINE (Ovid), EMBASE (Ovid), CINAHL (EBSCO) and Web of Science Core Collection) will be performed, and reference lists of included articles will be searched. We will conduct a two-step screening process, data extraction and analysis of the included studies. We will include all primary study designs that report on safety measurement and monitoring of any type of harms. Relevant grey literature will also be identified. We will exclude studies that only report results from facilities providing 24-hour skilled nursing care or specialised care services, and those not published in English or French. This protocol is registered on the Open Science Framework (osf.io/8rheq).

No ethical approval is needed for the review, and we plan to present the results at research conferences and in a peer-reviewed article. Our findings may inform future research studies that seek to support and improve safety practices in retirement homes.
