Young, unmarried men and sex: Do friends and partners shape risk behaviour?
Young people's sexual health is of growing concern. Past studies have been limited by their focus on the individual. More useful are interaction-orientated approaches that focus on partners and on the social context, rather than on the individual alone. This paper describes a study of 8068 men in Mexico City that takes this new approach. Multivariate techniques were used to examine use of contraception for pregnancy prevention and for sexually transmitted disease prophylaxis among unmarried, heterosexually active men aged 15-24. Friends and sexual partners were found to play an important role in shaping risk behaviour. To explain such behaviours adequately we need to take account of more than the characteristics of individuals isolated from their social contexts. © 2004 Taylor & Francis Ltd.
Gendered communication among young people in Mexico: Implications for sexual health interventions
Effective communication between partners is crucial for good sexual health, but is often difficult to achieve. This qualitative study shows how gendered communication can act as an important barrier to successful dialogue between men and women. Both content and manner of speaking are often gendered: not only can topics of conversation be socially defined as more or less appropriate for a speaker according to his or her sex, but men and women can also differ systematically in terms of the phrases and words they use. This may lead to a lack of the common forms of expression that are needed for effective communication. The study examines communication about sexuality among young men and women in low-income areas of Mexico City. The relationship between gender stereotypes of sexual behaviour and the gendered nature of communication strategies is explored. The negative consequences of gendered communication for effective dialogue between men and women are illustrated. Interventions that can enhance communication between men and women would be expected to have a positive impact on sexual health. This paper argues that research and interventions intended to improve sexual health may instead inadvertently reinforce communication barriers not only by failing to address the social pressures that exacerbate gendered communication, but also more insidiously, by using language that actively contributes to these pressures. An example of an intervention that avoids this problem is the Mexican programme "Gente Joven" ("Young People"). © 2003 Elsevier Ltd. All rights reserved.
Relationships between contraception and abortion: A review of the evidence
The relationship between levels of contraceptive use and the incidence of induced abortion continues to provoke heated discussion, with some observers arguing that use of abortion decreases as contraceptive prevalence rises and others claiming that increased use of family planning methods causes abortion incidence to rise. Abortion trends are examined in countries with reliable data on abortion and with contraceptive prevalence information from two points in time showing increases in contraceptive use. The role of changes in fertility in mediating the relationship between abortion and contraception is also explored. In seven countries - Kazakhstan, Kyrgyz Republic, Uzbekistan, Bulgaria, Turkey, Tunisia and Switzerland - abortion incidence declined as prevalence of modern contraceptive use rose. In six others - Cuba, Denmark, Netherlands, the United States, Singapore and the Republic of Korea - levels of abortion and contraceptive use rose simultaneously. In all six of these countries, however, overall levels of fertility were falling during the period studied. After fertility levels stabilized in several of the countries that had shown simultaneous rises in contraception and abortion, contraceptive use continued to increase and abortion rates fell. The most clear-cut example of this trend is the Republic of Korea. Rising contraceptive use results in reduced abortion incidence in settings where fertility itself is constant. The parallel rise in abortion and contraception in some countries occurred because increased contraceptive use alone was unable to meet the growing need for fertility regulation in situations where fertility was falling rapidly.
Do unintended pregnancies carried to term lead to adverse outcomes for mother and child? An assessment in five developing countries
This paper investigates whether children later reported as having been unwanted or mistimed at conception will, when compared with children reported as wanted, show adverse effects when the following criteria are applied: receipt of antenatal care before the sixth month of gestation, supervised delivery, full vaccination of the child, and child growth (stunting). The study uses data from five recent Demographic and Health Survey enquiries in Bolivia, Egypt, Kenya, Peru, and the Philippines. In Peru, children unwanted at conception were found to have significantly worse outcomes than other children, but in the other countries, a systematic effect was found only for receipt of antenatal care. Weak measurement of the complex concept of wantedness may have contributed to these results. Birth order of the child, with which wantedness is inextricably linked, has more powerful and pervasive effects, with first-born and second-born children being much less likely to show adverse effects.
COMPare: Qualitative analysis of researchers' responses to critical correspondence on a cohort of 58 misreported trials
Background: Discrepancies between pre-specified and reported outcomes are an important and prevalent source of bias in clinical trials. COMPare (Centre for Evidence-Based Medicine Outcome Monitoring Project) monitored all trials in five leading journals for correct outcome reporting, submitted correction letters on all misreported trials in real time, and then monitored responses from editors and trialists. From the trialists' responses, we aimed to answer two related questions. First, what can trialists' responses to corrections on their own misreported trials tell us about trialists' knowledge of correct outcome reporting? Second, what can a cohort of responses to a standardised correction letter tell us about how researchers respond to systematic critical post-publication peer review? Methods: All correspondence from trialists, published by journals in response to a correction letter from COMPare, was filed and indexed. We analysed the letters qualitatively and identified key themes in researchers' errors about correct outcome reporting, and approaches taken by researchers when their work was criticised. Results: Trialists frequently expressed views that contradicted the CONSORT (Consolidated Standards of Reporting Trials) guidelines or made inaccurate statements about correct outcome reporting. Common themes were: stating that pre-specification after trial commencement is acceptable; incorrect statements about registries; incorrect statements around the handling of multiple time points; and failure to recognise the need to report changes to pre-specified outcomes in the trial report. We identified additional themes in the approaches taken by researchers when responding to critical correspondence, including the following: ad hominem criticism; arguing that trialists should be trusted, rather than follow guidelines for trial reporting; appealing to the existence of a novel category of outcomes whose results need not necessarily be reported; incorrect statements by researchers about their own paper; and statements undermining transparency infrastructure, such as trial registers. Conclusions: Researchers commonly make incorrect statements about correct trial reporting. There are recurring themes in researchers' responses when their work is criticised, some of which fall short of the scientific ideal. Research on methodological shortcomings is now common, typically in the form of retrospective cohort studies describing the overall prevalence of a problem. We argue that prospective cohort studies which additionally issue correction letters in real time on each individual flawed study - and then follow-up responses from trialists and journals - are more impactful, more informative for those consuming the studies critiqued, more informative on the causes of shortcomings in research, and a better use of research resources.
COMPare: A prospective cohort study correcting and monitoring 58 misreported trials in real time
Background: Discrepancies between pre-specified and reported outcomes are an important source of bias in trials. Despite legislation, guidelines and public commitments on correct reporting from journals, outcome misreporting continues to be prevalent. We aimed to document the extent of misreporting, establish whether it was possible to publish correction letters on all misreported trials as they were published, and monitor responses from editors and trialists to understand why outcome misreporting persists despite public commitments to address it. Methods: We identified five high-impact journals endorsing Consolidated Standards of Reporting Trials (CONSORT) (New England Journal of Medicine, The Lancet, Journal of the American Medical Association, British Medical Journal, and Annals of Internal Medicine) and assessed all trials over a six-week period to identify every correctly and incorrectly reported outcome, comparing published reports against published protocols or registry entries, using CONSORT as the gold standard. A correction letter describing all discrepancies was submitted to the journal for all misreported trials, and detailed coding sheets were shared publicly. The proportion of letters published and delay to publication were assessed over 12 months of follow-up. Correspondence received from journals and authors was documented and themes were extracted. Results: Sixty-seven trials were assessed in total. Outcome reporting was poor overall and there was wide variation between journals on pre-specified primary outcomes (mean 76% correctly reported, journal range 25-96%), secondary outcomes (mean 55%, range 31-72%), and number of undeclared additional outcomes per trial (mean 5.4, range 2.9-8.3). Fifty-eight trials had discrepancies requiring a correction letter (87%, journal range 67-100%). Twenty-three letters were published (40%) with extensive variation between journals (range 0-100%). Where letters were published, there were delays (median 99 days, range 0-257 days). Twenty-nine studies had a pre-trial protocol publicly available (43%, range 0-86%). Qualitative analysis demonstrated extensive misunderstandings among journal editors about correct outcome reporting and CONSORT. Some journals did not engage positively when provided correspondence that identified misreporting; we identified possible breaches of ethics and publishing guidelines. Conclusions: All five journals were listed as endorsing CONSORT, but all exhibited extensive breaches of this guidance, and most rejected correction letters documenting shortcomings. Readers are likely to be misled by this discrepancy. We discuss the advantages of prospective methodology research sharing all data openly and pro-actively in real time as feedback on critiqued studies. This is the first empirical study of major academic journals' willingness to publish a cohort of comparable and objective correction letters on misreported high-impact studies. Suggested improvements include changes to correspondence processes at journals, alternatives for indexed post-publication peer review, changes to CONSORT's mechanisms for enforcement, and novel strategies for research on methods and reporting.
Reducing inequalities through greater diversity in clinical trials – As important for medical devices as for drugs and therapeutics
In medicine and public health, the randomised controlled trial (RCT) is generally considered the key generator of ‘gold standard’ evidence. However, basic and clinical research and trials are often unrepresentative of real-world populations. Recruiting insufficiently diverse cohorts of participants in trials (e.g. in terms of socioeconomic status, racial and ethnic background, or sex and gender) may not only overstate the general effectiveness of a technology; it may also actively increase health inequalities. We highlight some general issues in this domain, before discussing several specific illustrative examples in the context of medical devices. High quality evidence on factors that would improve trial recruitment is extremely limited. There is a clear need for research on candidate strategies for improving recruitment of under-represented groups in RCTs. These could include, for example, offering various forms of financial incentives; non-monetary incentives, such as preferential access to the technologies that are being tested if they are found to be effective; and various types of informational messages and nudges; as well as involvement of community partners and champions in the recruitment process. Ideally, recruitment practices should ultimately be based on evidence generated from RCTs. Studies Within a Trial (SWAT), where randomised experiments are built into the actual recruitment processes in RCTs, are an ideal way to gain this evidence. SWAT studies are seeing an increase in traction, as indicated by funding streams in bodies such as the UK-based NIHR. Making greater funding available for studies of this kind is needed to improve the evidence base on how best to improve diversity in trial recruitment.
Representativeness, Vaccination Uptake, and COVID-19 Clinical Outcomes 2020-2021 in the UK Oxford-Royal College of General Practitioners Research and Surveillance Network: Cohort Profile Summary
Background: The Oxford-Royal College of General Practitioners (RCGP) Research and Surveillance Centre (RSC) is one of Europe’s oldest sentinel systems, working with the UK Health Security Agency (UKHSA) and its predecessor bodies for 55 years. Its surveillance report now runs twice weekly, supplemented by online observatories. In addition to conducting sentinel surveillance from a nationally representative group of practices, the RSC is now also providing data for syndromic surveillance. Objective: The aim of this study was to describe the cohort profile at the start of the 2021-2022 surveillance season and recent changes to our surveillance practice. Methods: The RSC’s pseudonymized primary care data, linked to hospital and other data, are held in the Oxford-RCGP Clinical Informatics Digital Hub, a Trusted Research Environment. We describe the RSC’s cohort profile as of September 2021, divided into a Primary Care Sentinel Cohort (PCSC)—collecting virological and serological specimens—and a larger group of syndromic surveillance general practices (SSGPs). We report changes to our sampling strategy that brings the RSC into alignment with European Centre for Disease Control guidance and then compare our cohort’s sociodemographic characteristics with Office for National Statistics data. We further describe influenza and COVID-19 vaccine coverage for the 2020-2021 season (week 40 of 2020 to week 39 of 2021), with the latter differentiated by vaccine brand. Finally, we report COVID-19–related outcomes in terms of hospitalization, intensive care unit (ICU) admission, and death. Results: As a response to COVID-19, the RSC grew from just over 500 PCSC practices in 2019 to 1879 practices in 2021 (PCSC, n=938; SSGP, n=1203). This represents 28.6% of English general practices and 30.59% (17,299,780/56,550,136) of the population. In the reporting period, the PCSC collected >8000 virology and >23,000 serology samples. The RSC population was broadly representative of the national population in terms of age, gender, ethnicity, National Health Service Region, socioeconomic status, obesity, and smoking habit. The RSC captured vaccine coverage data for influenza (n=5.4 million) and COVID-19, reporting dose one (n=11.9 million), two (n=11 million), and three (n=0.4 million) for the latter as well as brand-specific uptake data (AstraZeneca vaccine, n=11.6 million; Pfizer, n=10.8 million; and Moderna, n=0.7 million). The median (IQR) number of COVID-19 hospitalizations and ICU admissions was 1181 (559-1559) and 115 (50-174) per week, respectively. Conclusions: The RSC is broadly representative of the national population; its PCSC is geographically representative and its SSGPs are newly supporting UKHSA syndromic surveillance efforts. The network captures vaccine coverage and has expanded from reporting primary care attendances to providing data on onward hospital outcomes and deaths. The challenge remains to increase virological and serological sampling to monitor the effectiveness and waning of all vaccines available in a timely manner.
The role of the enrolling clinician in emergency research conducted under an exception from informed consent
The Exception from Informed Consent (EFIC) permits patient enrolment into therapeutic emergency research where obtaining informed consent is challenging. Yet this fails to resolve a core ethical conflict in the research and has generated controversy. This is because existing justification and practice has relied on applying EFIC per study—a wholesale permission to enroll irrespective of circumstance—instead of per patient. Our novel justification for enrolment centers on applying EFIC per patient, which empowers the enrolling clinician to judge whether to enroll patients with an Exception. This contrasts with the idea that clinician judgment is surplus to the judgements already made by institutions in deciding the research may proceed. Instead, we show that enrolling clinician’s judgment is ethically significant and should not be overlooked: attending to this strengthens the research ethically and reduces controversy. There should be a bigger role for the clinician in the research enrolment space.
Rethinking ‘Recovery’: A Comparative Qualitative Analysis of Experiences of Intensive Care With COVID and Long Covid in the United Kingdom
ABSTRACTIntroductionInterpretations of ‘recovery’ from illness are complex and influenced by many factors, not least patient expectations and experiences. This paper examines meanings of ‘recovery’, and how it is strived towards, drawing on the example of COVID‐19 infection.MethodsDrawing on qualitative interviews (n = 93) conducted in the UK between February 2021 and July 2022, we compare adults' accounts of being admitted to an Intensive Care Unit (ICU) with COVID‐19 to accounts of being ill with Long COVID, defined as ongoing symptoms for at least 12 weeks postinfection. We conducted a multi‐stage comparative analysis using Nvivo to organise and code the data.ResultsWe identified similarities and differences in participants' descriptions of their ‘worlds of illness’. For both groups, perceptions of recovery were shaped by the novel, unknown nature of COVID‐19. Participants questioned the achievability of full restoration of prior states of health, highlighted the heterogeneity of ‘recovery trajectories’ and described the hard physical and emotional work of adjusting to changed selves. Themes that revealed differences in ‘worlds of illness’ described included the different baselines, waymarkers, and pathways of illness experiences. Differences in other people's responses to their illness were also evident. For ICU participants, hospitalisation, and especially ICU admission, conferred legitimate patient status and authenticity to their symptoms. Family, friends and healthcare professionals acknowledged their illness, celebrated their survival, and granted them latitude to recover. For Long Covid participants, their patient status often lacked comparable authenticity in others' eyes. They reported encountering a lack of recognition and understanding of their ongoing need to recover.ConclusionsThis study highlights how the meanings of illness ascribed by others can influence how recovery is experienced. Our findings highlight the importance of ensuring people are made to feel their illness experiences are legitimate, regardless of hospitalisation status, formal diagnosis or lack of medical knowledge and pathways. They also indicate the value of emphasising the different permutations, and lack of linearity, that recovery can take. This may help to help to guard against a lack of understanding for experiences of recovery which do not meet idealised notions.Patient or Public ContributionBoth studies were guided by an advisory panel that included patient and public involvement representatives with lived experience of Intensive Care/COVID experience and Long COVID respectively. Through regular meetings with the research teams, the advisory panel had input into all aspects of the study conduct, including recruitment methods and content of the interview topic guide and feedback on preliminary analyses. The Long COVID study also included a lived experience coinvestigator who contributed to data interpretation and analysis.
When life-saving measures lead to trauma: Subcapsular hepatic hematoma after CPR.
Cardiopulmonary resuscitation (CPR) is a critical intervention for cardiac arrest but can result in significant internal injuries due to the force of chest compressions. Among these, subcapsular hepatic hematoma is a rare and serious complication. Here we present a 55-year-old male with a history of alcohol abuse presented with a severe ischemic stroke and subsequently required CPR due to pulseless ventricular tachycardia. Following resuscitation, the patient developed a subcapsular hepatic hematoma, likely caused by the trauma of chest compressions. The patient also had a complex clinical course involving hemorrhagic conversion of the stroke and the need for anticoagulation due to bilateral pulmonary emboli, which further complicated the management of the hepatic hematoma. The identification of the hematoma was achieved through contrast-enhanced CT imaging after the patient exhibited worsening abdominal discomfort and signs of internal bleeding. The management focused on balancing the need for anticoagulation with the risks of further bleeding from the hematoma. A multidisciplinary approach was essential, involving close monitoring, potential surgical intervention, and careful adjustment of anticoagulant therapy. This case emphasizes the importance of recognizing the potential for internal injuries following CPR, especially in patients requiring anticoagulation. Early detection through imaging and a coordinated, multidisciplinary approach are crucial in managing such complications and improving patient outcomes.
Process evaluation in a randomised controlled trial of DREAMS-START (dementia related manual for sleep; strategies for relatives) for sleep disturbance in people with dementia and their carers
Introduction: DREAMS-START is a multicomponent intervention targeting sleep disturbance in people with dementia. To enhance understanding of the DREAMS-START randomised controlled trial, which showed improved sleep in the intervention compared to the control arm, we conducted a process evaluation exploring (i) DREAMS-START delivery, (ii) behaviour change mechanisms and (iii) contextual factors impacting outcomes. Methods: Mixed-methods design. We measured intervention adherence, fidelity and additional therapeutic process measures. We interviewed a sub-sample of intervention arm family carers and facilitators delivering DREAMS-START. We analysed data thematically guided by a prespecified theory of change logic model informed by the Theoretical Domains Framework. We measured movement using an actigraph worn by the person with dementia at baseline and at four- and eight-month follow-ups to explore potential mechanisms of action. Results: Attendance was good (82.8% attended ≥4/6 sessions). Mean fidelity score (95.4%; SD 0.08) and median score for all four process measures assessed (5/5; IQR 5–5) were high. We interviewed 43/188 family carers and 9/49 DREAMS-START facilitators. We identified three overarching themes aligned with our model: (i) knowledge and facilitation enable behaviour change, (ii) increasing sleep pressure and developing skills to manage sleep disturbances and (iii) Establishing a routine and sense of control. We were unable to collect sufficient data for pre-specified actigraphy analyses. Conclusion: Despite competing demands, carers attended DREAMS-START. It promoted behaviour change through supportive in-session reflection, increasing carer knowledge and skills. This was embedded between sessions and actions were positively reinforced as carers experienced changes. Results will inform future implementation in clinical services.
Sleep Health and White Matter Integrity in the UK Biobank
Many people experience impaired sleep health, yet knowledge about its neurobiological correlates is limited. As previous studies have found associations between white matter integrity and several sleep traits, white matter integrity could be causally implicated in poor sleep health. However, these studies were often limited by small sample sizes. In this study, we examine associations between multiple indices of white matter integrity and sleep health in 29,114 UK Biobank participants. Late chronotype, daytime sleepiness, insomnia symptoms and, most extensively, long sleep duration were independently associated with diffusion MRI markers of reduced white matter integrity. Previous findings showing an association between insomnia symptoms and decreased fractional anisotropy (FA) in the anterior internal capsule could not be replicated. To our knowledge, the current analysis is the first study to find an association between long sleep duration and impaired microstructural white matter integrity. Previous assumptions concerning the role of white matter integrity for insomnia are challenged.
Navigating the complexities of end-stage kidney disease (ESKD) from risk factors to outcome: insights from the UK Biobank cohort
Background: The global prevalence of end-stage kidney disease (ESKD) is increasing despite optimal management of traditional risk factors such as hyperglycaemia, hypertension, and dyslipidaemia. This study examines the influence of cardiorenal risk factors, socioeconomic status, and ethnic and cardiovascular comorbidities on ESKD outcomes in the general population. Methods: This cross-sectional study analysed data from 502,408 UK Biobank study participants recruited between 2006 and 2010. Multivariable logistic regression models were fitted to assess risk factors for ESKD, with results presented as adjusted odds ratio (aOR) and 95% confidence intervals (95% CI). Results: A total of 1191 (0.2%) of the study participants reported ESKD. Diabetes increased ESKD risk by 62% [1.62 (1.36–1.93)], with early-onset diabetes (before age 40) conferring higher odds compared to later-onset (after age 40) [2.26 (1.57–3.24)]. Similarly, early-onset hypertension (before age 40), compared to later onset (after age 40), increased ESKD odds by 73% [1.73 (1.21–2.44)]. Cardiovascular comorbidities, including stroke, hypertension, myocardial infarction and angina, were strongly associated with ESKD [5.97 (3.99–8.72), 5.35 (4.38–6.56), 4.94 (3.56–6.78), and 4.89 (3.47–6.81)], respectively. Males were at 22% higher risk of ESKD than females [1.22 (1.04–1.43)]. Each additional year of diabetes duration increased ESKD odds by 2% [1.02 (1.01–1.03)]. Non-white ethnicity, compared to white and socioeconomically most deprived, compared to the least deprived quintiles, were at 70% and 83% higher odds of ESKD. Each unit of HbA1c rise increased the odds of ESKD by 2%. Compared to microalbuminuria, macroalbuminuria increased the odds of ESKD by almost 10-fold [9.47 (7.95–11.27)] while normoalbuminuria reduced the odds by 73% [0.27 (0.22–0.32)]. Conclusions: Early onset of diabetes and hypertension, male sex, non-white ethnicity, deprivation, poor glycaemic control, and prolonged hyperglycaemia are significant risk factors for ESKD. These findings highlight the complexity of ESKD and the need for multifactorial targeted interventions in high-risk populations. Clinical trial number: Not applicable.
Impact of increasing CD4 count threshold eligibility for antiretroviral therapy initiation on advanced HIV disease and tuberculosis prevalence and incidence in South Africa: an interrupted time series analysis.
INTRODUCTION: We investigated the impact of increasing CD4 count eligibility for antiretroviral therapy (ART) initiation on advanced HIV disease (AHD) and tuberculosis (TB) prevalence and incidence among people living with HIV (PLHIV) in South Africa. METHODS: We conducted an interrupted time series analysis with de-identified data of PLHIV aged ≥15 years initiating ART between April 2012 and February 2020 at 65 primary healthcare clinics in KwaZulu-Natal, South Africa. Outcomes included monthly proportions of new ART initiators presenting with AHD (CD4 count <200 cells/µL) and TB disease. We created a cohort of monthly ART initiators without TB and evaluated the cumulative incidence of TB within 12 months follow-up. We used segmented binomial regression models to estimate relative risks (RR) of outcomes, allowing for a step and slope change after expanding the ART initiation CD4 count eligibility from <350 to <500 cells/µL in January 2015 and following Universal Test and Treat (UTT) implementation in September 2016. RESULTS: Among 209 984 participants, median age was 32 (range: 26-38), and 141 499 (67.4%) were female. After January 2015, the risk of AHD at initiation decreased in step by 25.0% (RR=0.750, 95% CI 0.688 to 0.812) and further reduced by 26.9% following UTT implementation (RR=0.731, 95% CI 0.681 to 0.781). The risk of TB at initiation also decreased in step by 27.6% after January 2015 (RR=0.724, 95% CI 0.651 to 0.797) and further decreased by 17.4% after UTT implementation (RR=0.826, 95% CI 0.711 to 0.941) but remained stable among initiators with AHD. Among the incidence cohort, we saw a step decrease in the risk of new TB by 31.4% (RR=0.686, 95% CI 0.465 to 0.907) following UTT implementation. Among the incidence cohort with AHD, there was weak evidence of a step decrease in the risk of new TB (RR=0.755, 95% CI 0.489 to 1.021), but the slope decreased by 9.7% per month (RR=0.903, 95% CI 0.872 to 0.934) following UTT implementation. CONCLUSIONS: Our data support the added benefit of decreased TB co-burden with expanded ART access. Early diagnosis and immediate linkage to care should be prioritised among PLHIV.
Differences in the risk of frailty based on care receipt, unmet care needs and socio-economic inequalities: A longitudinal analysis of the English Longitudinal Study of Ageing
Background: The older population is increasingly reliant on social care, especially those who are frail. However, an estimated 1.5 million people over 65 in England have unmet care needs. The relationship between receiving care, or receiving insufficient care, and changes in frailty status remains unclear. Objectives: To investigate the associations between care receipt (paid or unpaid), unmet care needs, frailty status, and mortality. Design: We used multistate models to estimate the risk of increasing or decreasing levels of frailty, using English Longitudinal Study of Ageing (ELSA) data. Covariates included age, gender, wealth, area deprivation, education, and marital status. Care status was assessed through received care and self-reported unmet care needs, while frailty status was determined using a frailty index. Participants: 15,003 individuals aged 50+, using data collected over 18 years (2002–2019). Results: Individuals who receive care are more susceptible to frailty and are less likely to recover from frailty to a less frail state. The hazard ratio of males receiving care transitioning from prefrailty to frailty was 2.1 [95 % CI: 1.7–2.6] and for females 1.8 [1.5–2.0]. Wealth is an equally influential predictor of changes in frailty status: individuals in the lowest wealth quintile who do not receive care are as likely to become frail as those in the highest wealth quintile who do receive care. As individuals receiving care (including unpaid care) are likely to be in poorer health than those who do not receive care, this highlights stark inequalities in the risk of frailty between the richest and poorest individuals. Unmet care needs were associated with transitioning from prefrailty to frailty for males (hazard ratio: 1.7 [1.2–2.4]) but not for females. Conclusions: Individuals starting to receive care (paid or unpaid) and people in the poorest wealth quintile are target groups for interventions aimed at delaying the onset of frailty.
Uptake of patient enrolment in primary care and associated factors: a systematic review and meta-analysis
Background: Patient enrolment in primary care refers to the formal process of registering patients with a specific primary care provider, team, or practice. This approach is often expected to enhance continuity and coordination of care. However, limited information exists on the uptake of patient enrolment and its associated characteristics. This review aimed to estimate the uptake of patient enrolment in primary care and examine factors associated with decisions around enrolment. Methods: Eight electronic databases (PubMed, Cochrane Register of Systematic Reviews, Embase, CINAHL, PsycINFO, PAIS, Web of Science, and Scopus) were searched for peer-reviewed articles published from January 2014 to July 2024. Findings from included studies were extracted and synthesised, with uptake estimated through meta-analysis and factors associated with enrolment summarised narratively. Review registration: PROSPERO CRD42024597078. Results: Ten studies across nine publications were included. Of these, eight studies with 27,919,216 participants were included in the meta-analysis. The results showed a pooled patient enrolment uptake rate of 71.4% (95% Confidence Interval [CI]: 13.6–97.5%). There was no significant difference in enrolment rates between population-wide and program-based enrolment (72.4% vs. 73.5%; p = 0.980). Several associated factors were identified in three publications. Women showed higher enrolment rates than men (adjusted odds ratio [aOR] = 1.07, 95% CI: 1.07–1.08), while recently arrived immigrants in a country had lower enrolment rates than the established population (aOR = 0.40, 95% CI: 0.40–0.41). Patients living in small urban/suburban/rural areas had higher enrolment rates than those in large urban/metropolitan regions (aORs: 1.17–2.18). Higher socioeconomic level was associated with increased rates of enrolment. Patients with some specific chronic health conditions, such as those with diagnosed mental illness or substance use disorders, had lower enrolment rates. Conclusions: The findings reveal that more than two-thirds of patients were enrolled with a primary care provider or practice; enrolment was influenced by demographic, geographic, socioeconomic, and clinical factors. Lower enrolment among men, recent immigrants, individuals living in large urban/metropolitan areas, lower socioeconomic groups, and those with certain health conditions may indicate potential barriers to health service access and opportunities for enrolment. Addressing these disparities is essential to promote equitable access and enhance opportunities for continuity and coordination of primary care.
Open science interventions to improve reproducibility and replicability of research: a scoping review.
Various open science practices have been proposed to improve the reproducibility and replicability of scientific research, but not for all practices, there may be evidence they are indeed effective. Therefore, we conducted a scoping review of the literature on interventions to improve reproducibility. We systematically searched Medline, Embase, Web of Science, PsycINFO, Scopus and Eric, on 18 August 2023. Any study empirically evaluating the effectiveness of interventions aimed at improving the reproducibility or replicability of scientific methods and findings was included. We summarized the retrieved evidence narratively and in evidence gap maps. Of the 105 distinct studies we included, 15 directly measured the effect of an intervention on reproducibility or replicability, while the remainder addressed a proxy outcome that might be expected to increase reproducibility or replicability, such as data sharing, methods transparency or pre-registration. Thirty studies were non-comparative and 27 were comparative but cross-sectional observational designs, precluding any causal inference. Despite studies investigating a range of interventions and addressing various outcomes, our findings indicate that in general the evidence base for which various interventions to improve reproducibility of research remains remarkably limited in many respects.
