ABSTRACT

OBJECTIVES: The use of electronic patient-reported outcome (ePRO) systems to support the management of patients with chronic kidney disease is increasing. This mixed-methods study aimed to comprehensively identify existing and developing ePRO systems, used in nephrology settings globally, ascertaining key characteristics and factors for successful implementation.

STUDY DESIGN: ePRO systems and developers were identified through a scoping review of the literature and contact with field experts. Developers were invited to participate in a structured survey, to summarise key system characteristics including: (1) system objectives, (2) population, (3) PRO measures used, (4) level of automation, (5) reporting, (6) integration into workflow and (7) links to electronic health records/national registries. Subsequent semistructured interviews were conducted to explore responses.

SETTING AND PARTICIPANTS: Eligible systems included those being developed or used in nephrology settings to assess ePROs and summarise results to care providers. System developers included those with a key responsibility for aspects of the design, development or implementation of an eligible system.

ANALYTICAL APPROACH: Structured survey data were summarised using descriptive statistics. Interview transcripts were analysed using Codebook Thematic Analysis using domains from the Consolidated Framework for Implementation Research.

RESULTS: Fifteen unique ePRO systems were identified across seven countries; 10 system developers completed the structured survey and 7 participated in semistructured interviews. Despite system heterogeneity, reported features required for effective implementation included early and sustained patient involvement, clinician champions and expanding existing electronic platforms to integrate ePROs. Systems demonstrated several common features, with the majority being implemented within research settings, thereby affecting system implementation readiness for real-world application.

CONCLUSIONS: There has been considerable research investment in ePRO systems. The findings of this study outline key system features and factors to support the successful implementation of ePROs in routine kidney care.Cite Now.

ABSTRACT

OBJECTIVES: Studies on health effects of tobacco often rely on self-reported exposure data, which is subjective and can lead to misclassification. The aim of this study was to describe the prevalence of cigarette smoking, snus and e-cigarette use, as well as to validate self-reported tobacco use among young adults in Sweden.

METHOD: Participants of a population-based Swedish cohort (n=3052), aged 22-25 years, assessed their tobacco use in a web questionnaire. Urinary cotinine was analysed in a subsample of the study population (n=998). The agreement between self-reported tobacco use and urinary cotinine was assessed using Cohen’s Kappa coefficient (κ) at a cut-off level of 50 ng/mL.

RESULTS: Patterns of tobacco use differed between men and women. Among men, 20.0% reported daily snus use, 5.8% daily cigarette smoking and 5.6% any e-cigarette use. In contrast, 3.2% of the women reported daily snus use, 9.0% daily cigarette smoking and 2.4% any e-cigarette use. Among the tobacco use categories, daily snus users had the highest levels of cotinine. Of reported non-tobacco users, 3.5% had cotinine levels above the cut-off, compared with 68.0% among both occasional cigarette smokers and snus users, 67.5% among all e-cigarette users and 94.7% and 97.8% among daily cigarette smokers and snus users, respectively. Agreement between self-reported tobacco use and urinary cotinine was classified as strong for daily use of cigarettes (κ=0.824) and snus (κ=0.861), while moderate to weak for occasional smoking (κ=0.618), occasional snus use (κ=0.573) and any e-cigarette use (κ=0.576).

CONCLUSIONS: We found high validity of self-reported tobacco use in our study population, particularly for daily tobacco use. Further, we found that daily snus users were exposed to high levels of cotinine. Together with previous findings, our results indicate good validity of self-reported tobacco use among young adults.

ABSTRACT

INTRODUCTION: Readiness to be freed from ventilatory support can be evaluated by spontaneous breathing trial (SBT) assessing the patient’s ability to sustain respiratory effort after extubation. Current SBT practices are heterogenous and there are few physiological studies on the topic. The objective of this study is to assess which SBT best reproduces inspiratory effort to breathe after extubation depending on the patient’s illness.

METHODS AND ANALYSIS: This will be a multicentre randomised cross-over physiological study, in a large population, in the era of modern intensive care units using last generation modern ventilators. Each included patient will perform three 15-minute SBTs in a random order: pressure support ventilation (PSV) level of 7 cmH₂O with positive end expiratory pressure (PEEP) level of 0 cmH₂O, PSV 0 cmH₂O with PEEP 0 cmH₂O and T-piece trial. A rest period of baseline state ventilation will be observed between the SBTs (10 min) and before extubation (30 min). Primary outcome will be the inspiratory muscle effort, reflected by pressure time product per minute (PTPmin). This will be calculated from oesophageal pressure measurements at baseline state, before and after each SBT and 20 min after extubation. Secondary outcomes will be PTPmin at 24 hours and 48 hours after extubation, changes in physiological variables and respiratory parameters at each step, postextubation respiratory management and the rate of successful extubation. One hundred patients with at least 24 hours of invasive mechanical ventilation will be analysed, divided into five categories of critical illness: abdominal surgery, brain injury, chest trauma, chronic obstructive pulmonary disease and miscellaneous (pneumonia, sepsis, heart disease).

ETHICS AND DISSEMINATION: The study project was approved by the appropriate ethics committee (2019-A01063-54, Comité de Protection des Personnes TOURS – Région Centre – Ouest 1, France). Informed consent is required, for all patients or surrogate in case of inability to give consent.

ABSTRACT

INTRODUCTION: Men in sub-Saharan Africa are less likely than women to initiate antiretroviral therapy (ART) and more likely to have longer cycles of disengagement from ART programmes. Treatment interventions that meet the unique needs of men are needed, but they must be scalable. We will test the impact of various interventions on 6-month retention in ART programmes among men living with HIV who are not currently engaged in care (never initiated ART and ART clients with treatment interruption).

METHODS AND ANALYSIS: We will conduct a programmatic, individually randomised, non-blinded, controlled trial. ‘Non-engaged’ men will be randomised 1:1:1 to either a low-intensity, high-intensity or stepped arm. The low-intensity intervention includes one-time male-specific counseling+facility navigation only. The high-intensity intervention offers immediate outside-facility ART initiation+male-specific counselling+facility navigation for follow-up ART visits. In the stepped arm, intervention activities build in intensity over time for those who do not re-engage in care with the following steps: (1) one-time male-specific counselling+facility navigation→(2) ongoing male mentorship+facility navigation→(3) outside-facility ART initiation+male-specific counselling+facility navigation for follow-up ART visits. Our primary outcome is 6-month retention in care. Secondary outcomes include cost-effectiveness and rates of adverse events. The primary analysis will be intention to treat with all eligible men in the denominator and all men retained in care at 6 months in the numerator. The proportions achieving the primary outcome will be compared with a risk ratio, corresponding 95% CI and p value computed using binomial regression accounting for clustering at facility level.

ETHICS AND DISSEMINATION: The Institutional Review Board of the University of California, Los Angeles and the National Health Sciences Research Council in Malawi have approved the trial protocol. Findings will be disseminated rapidly in national and international forums and in peer-reviewed journals and are expected to provide urgently needed information to other countries and donors.

ABSTRACT

INTRODUCTION: The timely treatment of acute myocardial infarction (AMI) patients is of utmost importance, and yet, there remains a significant disparity between urban and rural areas in China due to the unequal distribution of medical resources. The manifestation of symptoms and psychosocial factors play a crucial role in shaping medical decisions for AMI patients. It is well established that minimising prehospital delay (PHD) is crucial for the successful implementation of recanalisation therapy and reducing mortality in out-of-hospital settings. However, there remains a paucity of studies investigating the correlation between illness perception, symptom response, social support, and PHD in AMI patients.

AIM: The aim of this study was to analyse the relationship pathways between symptom response, illness perception, social support and PHD time in patients with AMI in rural areas of China.

METHODS: A primary care-based cross-sectional study was designed to investigate the inpatients initially diagnosed with AMI in the emergency department of three tertiary care hospitals in three counties in northern Zhejiang Province by convenience sampling method from January 2023 to December 2023. A minimum of 286 patients will be enrolled (voluntary response sample). Each participant will complete a paper-based questionnaire to gather research outcomes. Statistical analyses will be performed using logistic regression and structural equation model with PHD as main outcome parameter.

DISCUSSION: This is the first study of the factors influencing PHD in AMI in rural China using structural equation model. Our study will address this gap in the available research. The implementation and findings of this study may provide a reliable basis for reducing PHD in AMI patients in rural areas and establish a relevant theoretical foundation for the implementation of targeted interventions and risk prevention measures in primary care hospitals.

ABSTRACT

OBJECTIVES: Health workers are at particular risk of contracting the COVID-19. However, non-acceptance of COVID-19 vaccination has been a noticeable challenge the world over and in Nigeria where supply constraints have also been an issue. We evaluated COVID-19 vaccination acceptance (the uptake, hesitancy, intention to receive and timeliness of the intention to receive) and the determinants, and the predictive power of acceptance factor compared with availability/access factor, among health workers in Ebonyi state.

METHODS: We conducted an online-offline survey, between 12 March 2022 and 9 May 2022, among all consenting health workers (clinical/non-clinical, public/private) working/living in Ebonyi state and who were selected by convenience and snowballing techniques. Data were collected using structured self-administered questionnaire distributed via WhatsApp and interviewer-administered questionnaire in KoBoCollect installed in android devices. Data were analysed using descriptive statistics and generalised linear models.

RESULTS: 1276 health workers were surveyed. Uptake was 68.2% vaccinated, 47.4% fully vaccinated and 20.9% partially vaccinated. Hesitancy was 22.6% or 71.2% among the unvaccinated (76.3% of hesitancy due to refusal and 23.7% to delay). Intention to receive was 36.0% of which 55.1% gave the intended time (days) to receive with a median (IQR) of 30 days (7-133). The strongest and most important predictor of COVID-19 vaccination acceptance was COVID-19 vaccination expectations and perceptions. Other important predictors were COVID-19/COVID-19 vaccination process experiences and perceptions. Acceptance factor was a stronger predictor compared with availability/access factor.

CONCLUSION: The slow pace of COVID-19 vaccination coverage among the health workers in Ebonyi state/Nigeria may encounter a bottle-neck due to the high refusal rate among the unvaccinated. COVID-19 vaccination policy interventions in Nigeria and other similar settings should, in addition to sustaining availability and access, prioritise improvement of COVID-19 vaccination expectations and perceptions (regarding importance/safety/effectiveness) and COVID-19 risk communication among the health workers.

ABSTRACT

OBJECTIVE: This study explores the effectiveness of a comprehensive licensure review and adaptive quizzing assignments intervention in improving the performance of undergraduate senior nursing students on the end-of-programme exit exam.

DESIGN: A quasi-experimental single-group design was used to compare pretest and post-test scores through computerised adaptive tests.

SETTING: The setting was a nursing college in Saudi Arabia.

PARTICIPANTS: The study included 292 senior nursing students enrolled in the Bachelor of Science in Nursing programme.

INTERVENTION: A comprehensive licensure review bundled with adaptive quizzing assignments was delivered over 15 weeks in the academic year 2021-2022. The bundle was guided by the elaboration theory, and it included 3-hour synchronous lectures every week and 23 adaptive quizzing assignments that covered weekly content.

PRIMARY AND SECONDARY OUTCOME MEASURES: Students’ mastery scores and the percentage of correct answers were the primary and secondary measures, respectively. Both measures were collected in the pretest and post-test (exit examination). Additionally, demographic characteristics were collected in the pre-test using an online survey.

RESULTS: The overall mean of the mastery score was statistically significantly higher in the exit exam (M=2.51, SD=1.70) than in the pretest (M=1.45, SD=0.44; p<0.001). Although the overall mean of the mastery score in the exit exam did not reach the cut-off score, students who demonstrated the required knowledge and satisfactory performance in the pretest achieved a mastery score above the cut-off. The percentage of correct answers was statistically significantly higher in the exit exam (M=58.59%, SD=9.50) than in the pretest (M=49.32%, SD=9.78; p<0.001). A statistically significant difference in students’ performance based on gender, age and grade point average was observed.

CONCLUSIONS: A comprehensive licensure review and adaptive quizzing assignments intervention bundle fostered the performance of undergraduate nursing students in the end-of-programme exit exam.

ABSTRACT

BACKGROUND: Hypoechoic peri-stent areas in duplex ultrasonography (DUS) (ie, “halo”) have been noted following femoropopliteal artery stenting.

OBJECTIVES: This study sought to investigate the prevalence, risk factors, and potential safety implications of hypoechoic halos identified with DUS following stent implantation in the IMPERIAL (ELUVIA Drug-Eluting Stent Versus Zilver PTX Stent) and EMINENT (Trial Comparing ELUVIA Versus Bare Metal Stent in Treatment of Superficial Femoral and/or Proximal Popliteal Artery) trials.

METHODS: The IMPERIAL and EMINENT studies of femoropopliteal artery stenting included polymer-based drug-eluting stent, nonpolymer drug-coated stent, and bare metal stent treatment arms. A dedicated DUS protocol was implemented for core laboratory assessment of halo presence at study follow-up visits. Logistic regressions were used to investigate risk factors for a halo sign and its impact on clinically driven target lesion revascularization and primary patency.

RESULTS: Diagnostic DUS imaging from 659 patients was obtained at time points ranging from 6 months to 5 years post-stent implantation. Halo prevalence ranged from 20% to 35% of patients with diagnostic DUS and was present at all time intervals. Halos were identified surrounding all stent types. In analyses of patients with diagnostic imaging from at least 2 visits, halo presence typically persisted, with occasional cases of regression and development at later times. No statistically significant association was found for halo status (ie, halo vs no halo) on 1-year clinically driven target lesion revascularization (OR: 1.27; 95% CI: 0.70-2.30; P = 0.4240) or primary patency (OR: 0.68; 95% CI: 0.43-1.07; P = 0.0927).

CONCLUSIONS: A hypoechoic halo following a femoropopliteal stent procedure is a common occurrence associated with all studied stent types. The presence of a halo appears to be benign with no associated clinical sequelae or effect on target vessel revascularization rates within 1 year of stent implantation.

ABSTRACT

BACKGROUND: Increasing evidence indicates that ambient outdoor temperature could affect mental health, which is especially concerning in the context of climate change. We aimed to comprehensively analyse the current evidence regarding the associations between ambient temperature and mental health outcomes.

METHODS: We did a systematic review and meta-analysis of the evidence regarding associations between ambient outdoor temperature and changes in mental health outcomes. We searched WebOfScience, Embase, PsychINFO, and PubMed for articles published from database origin up to April 7, 2022. Eligible articles were epidemiological, observational studies in humans of all ages, which evaluated real-world responses to ambient outdoor temperature, and had mental health as a documented outcome; studies of manipulated or controlled temperature or those with only physical health outcomes were excluded. All eligible studies were synthesised qualitatively. If three or more studies reported the same or equivalent effect statistics and if they had equivalent exposure, outcome, and metrics, the studies were pooled in a random-effects meta-analysis. The risk of bias for individual studies was assessed using the Newcastle-Ottawa Scale. The quality of evidence across studies was assessed using the Office of Health Assessment and Translation (OHAT) approach.

FINDINGS: 114 studies were included in the systematic review, of which 19 were suitable for meta-analysis. Three meta-analyses were conducted for suicide outcomes: a 1°C increase in mean monthly temperature was associated with an increase in incidence of 1·5% (95% CI 0·8-2·2, p<0·001; n=1 563 109, seven effects pooled from three studies); a 1°C increase in mean daily temperature was associated with an increase in incidence of 1·7% (0·3-3·0, p=0·014; n=113 523, five effects pooled from five studies); and a 1°C increase in mean monthly temperature was associated with a risk ratio of 1·01 (95% CI 1·00-1·01, p<0·001; n=111 794, six effects pooled from three studies). Three meta-analyses were conducted for hospital attendance or admission for mental illness: heatwaves versus non-heatwave periods were associated with an increase in incidence of 9·7% (95% CI 7·6-11·9, p<0·001; n=362 086, three studies); the risk ratio at the 99th percentile of daily mean temperature compared with the 50th percentile was 1·02 (95% CI 1·01-1·03, p=0·006; n=532 296, three studies); and no significant association was found between a 10°C increase in daily mean temperature and hospital attendance. In a qualitative narrative synthesis, we found that ambient outdoor temperature (including absolute temperatures, temperature variability, and heatwaves) was positively associated with attempted and completed suicides (86 studies), hospital attendance or admission for mental illness (43 studies), and worse outcomes for community mental health and wellbeing (19 studies), but much of the evidence was of low certainty with high heterogeneity.

INTERPRETATION: Increased temperature and temperature variability could be associated with increased cases of suicide and suicidal behaviour, hospital attendance or admission for mental illness, and poor community health and wellbeing. Climate change is likely to increase temperature anomalies, variability, and heatwaves as well as average temperatures; as such, health system leaders and policy makers must be adequately prepared and should develop adaptation strategies. More high-quality, standardised research is required to improve our understanding of these effects.

FUNDING: None.

ABSTRACT

BACKGROUND: Patients with scleroderma require a lifetime of treatment and frequent contacts with rheumatologists and other health care professionals. Although publicly funded health care systems in Canada cover many costs, patients may still face a substantial financial burden in accessing care. The purpose of this study was to quantify out-of-pocket costs borne by people with scleroderma in Canada and compare this burden for those living in large communities and smaller communities.

METHODS: We analyzed responses to a Web-based survey of people living in Canada with scleroderma. Respondents reported annual out-of-pocket medical, travel and accommodation and other nonmedical costs (2019 Canadian dollars). We used descriptive statistics to describe travel distance and out-of-pocket costs. We used a 2-part model to estimate the impact on out-of-pocket costs of living in a large urban centre (≥ 100 000 population), compared with smaller urban centres or rural areas (< 100 000 population). We generated combined mean estimates from the 2-part models using predictive margins.

RESULTS: The survey included 120 people in Canada with scleroderma. The mean, annual, total out-of-pocket costs were $3357 (standard deviation $5580). Respondents living in smaller urban centres and rural areas reported higher mean total costs ($4148, 95% confidence interval [CI] $3618-$4680) and travel or accommodation costs ($1084, 95% CI $804-$1364) than those in larger urban centres (total costs $2678, 95% CI $2252-$3104; travel or accommodation costs $332, 95% CI $207-$458).

INTERPRETATION: Many patients with scleroderma incur considerable out-of-pocket costs, and this burden is exacerbated for those living in smaller urban centres and rural areas. Health care systems and providers should consider ways to alleviate this burden and support equitable access to care.
