RESUMO

Individuals' vulnerability to the risk of COVID-19 infection varies due to their health, socioeconomic, and living circumstances, which also affect the effectiveness of implementing non-pharmacological interventions (NPIs). In this study, we analysed socioeconomic-related inequalities in COVID-19 vulnerability using data from the nationally representative South African General Household Survey 2019. We developed a COVID-19 vulnerability index, which includes health and social risk factors for COVID-19 exposure and susceptibility. The concentration curve and concentration index were used to measure socioeconomic-related inequalities in COVID-19 vulnerability. Recentred influence function regression was then utilised to decompose factors that explain the socioeconomic-related inequalities in COVID-19 vulnerability. The concentration index estimates were all negative and highly significant (p < 0.01), indicating that vulnerability to COVID-19 was more concentrated among the poor. According to the decomposition analysis, higher income and education significantly (p < 0.01) positively impacted lowering socioeconomic-related COVID-19 vulnerability. Living in an urban region, being Black, and old all had significant (p < 0.01) positive impacts on increasing socioeconomic-related COVID-19 vulnerability. Our findings contribute to a better understanding of socially defined COVID-19-vulnerable populations in South Africa and the implications for future pandemic preparedness plans.

RESUMO

The importance of clinical reasoning in patient care is well-recognized across all health professions. Validity evidence supporting high quality clinical reasoning assessment is essential to ensure health professional schools are graduating learners competent in this domain. However, through the course of a large scoping review, we encountered inconsistent terminology for clinical reasoning and inconsistent reporting of methodology, reflecting a somewhat fractured body of literature on clinical reasoning assessment. These inconsistencies impeded our ability to synthesize across studies and appropriately compare assessment tools. More specifically, we encountered: 1) a wide array of clinical reasoning-like terms that were rarely defined or informed by a conceptual framework, 2) limited details of assessment methodology, and 3) inconsistent reporting of the steps taken to establish validity evidence for clinical reasoning assessments. Consolidating our experience in conducting this review, we provide recommendations on key definitional and methodologic elements to better support the development, description, study, and reporting of clinical reasoning assessments.

RESUMO

BACKGROUND: Mental illness is a major disease burden in the world and disproportionately affects the socially disadvantaged, but studies on the longitudinal association of poverty with anxiety and stress are rare, especially in Asia. Using data from Hong Kong, we aimed to (1) assess the cross-sectional association of poverty with anxiety and stress at baseline, and (2) to examine whether baseline poverty and change in poverty status over time are associated with a subsequent change in anxiety and stress. METHODS: Data were obtained from two waves of a territory-wide longitudinal survey in Hong Kong, with sample sizes of n=1970 and n=1224 for baseline and follow-up, respectively. Poverty was measured with a Deprivation Index and income-poverty. Anxiety and stress symptoms were assessed using Chinese Depression, Anxiety and Stress Scale-21 Items. We conducted cross-sectional and longitudinal analyses on the association of poverty with anxiety and stress. OUTCOMES: Deprivation, but not income-poverty, was significantly associated with both outcomes at baseline. Increased deprivation over time was associated with greater score and increased risk of anxiety and stress. Persistent deprivation over time was associated with greater anxiety and stress, and increased risk of incident anxiety. INTERPRETATION: Deprivation could have significant independent effects on anxiety and stress, even after adjusting for the effects of income-poverty. Greater attention should be paid to deprivation in policymaking to tackle the inequalities of mental health problems, especially since stress and anxiety are precursors to more severe forms of mental illness and other comorbidities.

RESUMO

AIM: The objective was to study the long-term (lifetime) cost effectiveness of four different hepatitis C virus (HCV) treatment models of care (MOC) with directly acting antiviral drugs. METHODS: A cohort Markov model-based probabilistic cost-effectiveness analysis (CEA) was undertaken extrapolating to up to 30 years from cost and outcome data collected from a primary study involving a real-life Australian cohort. In this study, noncirrhotic patients treated for HCV from 1 March 2016 to 28 February 2017 at four major public hospitals and liaising sites in South Australia were studied retrospectively. The MOC were classified depending on the person providing patient workup, treatment and monitoring into MOC1 (specialist), MOC2 (mixed specialist and hepatitis nurse), MOC3 (hepatitis nurse) and MOC4 (general practitioner, GP). Incremental costs were estimated from the Medicare perspective. Incremental outcomes were estimated based on the quality-adjusted life years (QALY) gained by achieving a sustained virological response. A cost-effectiveness threshold of Australian dollar 50 000 per QALY gained, the implicit criterion used for assessing the cost-effectiveness of new pharmaceuticals and medical services in Australia was assumed. Net monetary benefit (NMB) estimates based on this threshold were calculated. RESULTS: A total of 1373 patients, 64% males, mean age 50 (SD ±11) years, were studied. In the CEA, MOC4 and MOC2 clearly dominated MOC1 over 30 years with lower costs and higher QALYs. Similarly, NMB was the highest in MOC4, followed by MOC2. CONCLUSION: Decentralized care using GP and mixed consultant nurse models were cost-effective ways of promoting HCV treatment uptake in the setting of unrestricted access to new antivirals.

RESUMO

BACKGROUND: We examined the association of housing affordability with physical and mental health in Hong Kong, where there is a lack of related research despite having the worst housing affordability problem in the world, considering potential mediating effect of deprivation. METHODS: A stratified random sample of 1978 Hong Kong adults were surveyed. Housing affordability was defined using the residual-income (after housing costs) approach. Health-related quality of life was assessed by the Short-Form Health Survey version 2 (SF-12v2), from which the physical component summary (PCS) and mental component summary (MCS) measures were derived. Multivariable linear regressions were performed to assess associations of housing affordability with PCS and MCS scores, adjusting for sociodemographic, socioeconomic and lifestyle factors. Mediation analyses were also conducted to assess the mediating role of deprivation on the effect of housing affordability on PCS or MCS. RESULTS: Dose-response relationships were observed between housing affordability and mean PCS score (ß (95% CI) compared with the highest affordable fourth quartile: -2.53 (-4.05 to -1.01), -2.23 (-3.54 to -0.92), -0.64 (-1.80 to 0.51) for the first, second and third quartiles, respectively) and mean MCS score (ß (95% CI): -3.87 (-5.30 to -2.45), -2.35 (-3.59 to -1.11), -1.28 (-2.40 to -0.17) for the first, second and third quartiles, respectively). Deprivation mediated 34.3% of the impact of housing unaffordability on PCS and 15.8% of that on MCS. CONCLUSIONS: Housing affordability affects physical and mental health, partially through deprivation, suggesting that housing policies targeting deprived individuals may help reduce health inequality in addition to targeting the housing affordability problem.

RESUMO

PURPOSE: An evidence-based approach to assessment is critical for ensuring the development of clinical reasoning (CR) competence. The wide array of CR assessment methods creates challenges for selecting assessments fit for the purpose; thus, a synthesis of the current evidence is needed to guide practice. A scoping review was performed to explore the existing menu of CR assessments. METHOD: Multiple databases were searched from their inception to 2016 following PRISMA guidelines. Articles of all study design types were included if they studied a CR assessment method. The articles were sorted by assessment methods and reviewed by pairs of authors. Extracted data were used to construct descriptive appendixes, summarizing each method, including common stimuli, response formats, scoring, typical uses, validity considerations, feasibility issues, advantages, and disadvantages. RESULTS: A total of 377 articles were included in the final synthesis. The articles broadly fell into three categories: non-workplace-based assessments (e.g., multiple-choice questions, extended matching questions, key feature examinations, script concordance tests); assessments in simulated clinical environments (objective structured clinical examinations and technology-enhanced simulation); and workplace-based assessments (e.g., direct observations, global assessments, oral case presentations, written notes). Validity considerations, feasibility issues, advantages, and disadvantages differed by method. CONCLUSIONS: There are numerous assessment methods that align with different components of the complex construct of CR. Ensuring competency requires the development of programs of assessment that address all components of CR. Such programs are ideally constructed of complementary assessment methods to account for each method's validity and feasibility issues, advantages, and disadvantages.

RESUMO

INTRODUCTION: Invasive meningococcal disease (IMD) primarily causes disease in young children and adolescents and can cause long-term disability. Many countries are considering implementation of meningococcal B and/or meningococcal ACWY vaccines to control meningococcal disease. Estimating the cost-effectiveness of meningococcal vaccine programme is hampered due to a lack of good quality costing and burden of disease data. This study aims to address this evidence gap by assessing the clinical, physical, neurocognitive, economic and societal impact of IMD on adolescents and young adults. METHODS AND ANALYSIS: A case-control study of 64 participants with confirmed IMD (15-24 years 11 months at time of disease) and 64 control participants (17-34 years 11 months) will be conducted in Australia from 2016 to 2020. All participants will undergo a neurocognitive assessment, full medical examination, pure tone audiometry assessment and complete quality of life and behavioural questionnaires. Meningococcal cases will be assessed 2-10 years posthospitalisation and a subset of cases will be interviewed to explore in depth their experiences of IMD and its impact on their life. Primary outcome measures include general intellectual functioning from the Wechsler Adult Intelligence Scale and overall quality of life from the Health Utilities Index. Secondary outcome measures include academic achievement, executive functioning, behaviour, hearing, psychological and physical functioning. Outcome measures will be compared between cases and controls using independent t-tests or ORs, or if any significant confounders are identified, adjusted analyses (analysis of covariance or adjusted ORs) will be conducted. Thematic analysis will be used to analyse transcribed interviews and a costing model will be used to project lifetime costs. ETHICS AND DISSEMINATION: The Adolescent MENingococcal Disease (AMEND) study has been approved by the Human Research Ethics Committee of the Women's and Children's Health Network (HREC/14/WCHN/024). The results will be disseminated via peer-reviewed publications, conference presentations, study participants, and meningococcal and meningitis foundations. TRIAL REGISTRATION NUMBER: NCT03798574.

RESUMO

Although Hong Kong is one of the richest cities in the world and has some of the best health outcomes such as long life expectancy, little is known about the people who are unable to access healthcare due to lack of financial means. Cross-sectional data from a sample of 2,233 participants aged 18 or above was collected from the first wave of the "Trends and Implications of Poverty and Social Disadvantages in Hong Kong" survey. Socio-demographic factors, lifestyle factors, and physical and mental health conditions associated with people who were unable to seek medical services due to lack of financial means in the past year were examined using forward stepwise logistic regression analyses. Of the 2,233 participants surveyed, 8.4% did not seek medical care due to lack of financial means during the past year. They were more likely to be income-poor. With respect to physical and mental health, despite having less likelihood to have multimorbidity, they tended to have higher levels of both anxiety and stress, poorer physical and mental health-related quality of life, and suffer from more severe disability and pain symptoms affecting their daily activities, when compared to the rest of the Hong Kong population. People who were denied of medical care due to financial barriers are generally sicker than people in the general Hong Kong population, implying that those with greater healthcare needs may have financial difficulties in receiving timely and appropriate medical care. Our findings suggest that inequity in healthcare utilization remains a critical issue in Hong Kong.

RESUMO

PURPOSE: In studying health inequality, poverty as measured by income is frequently used; however, this omits the aspects of non-monetary resources and social barriers to achieving improved living standard. Therefore, our study aimed to examine the associations of individual-level deprivation of material and social necessities with general physical and mental health beyond that of income poverty. METHODS: A territory-wide two-stage stratified random sample of 2282 community-dwelling Hong Kong adults was surveyed between 2014 and 2015. Income poverty and a Deprivation Index were used as the main independent variables. General health was assessed using the validated 12-item Short-Form Health Survey version 2, from which physical component summary and mental component summary were derived. RESULTS: Our results in multivariable ordinal logistic regressions consistently showed that, after adjusting for income poverty, socio-demographic and lifestyle factors, being deprived was significantly associated with worse physical (OR 1.66; CI 1.25-2.20) and mental health (OR 1.83; CI 1.43-2.35). Being income poor was also significantly associated with worse mental health (OR 1.63; CI 1.28-2.09) but only marginally with physical health (OR 1.34; CI 1.00-1.80) after adjustments. CONCLUSIONS: Income does not capture all aspects of poverty that are associated with adverse health outcomes. Deprivation of non-monetary resources has an independent effect on general health above and beyond the effect of income poverty. Policies should move beyond endowment and take into account the multidimensionality of poverty, in order to address the problem of health inequality.

RESUMO

PURPOSE: We aimed to assess the preparedness of junior doctors to use vancomycin, and to determine whether attending an educational session and being provided pocket guidelines were associated with self-reported confidence and objective knowledge. METHODS: This was a 2-component cross-sectional study. A 60-minute educational session was implemented and pocket guidelines were provided. Preparedness was evaluated by a self-reported confidence survey in the early and late stages of each training year, and by continuing medical education (CME) knowledge scores. RESULTS: Self-confidence was higher among those later in the training year (n=75) than in those earlier (n=120) in the year for all questions. In the late group, vancomycin education was associated with higher self-confidence regarding the frequency of therapeutic drug monitoring (P=0.02) and dose amendment (P=0.05); however, the confidence for initial monitoring was lower (P<0.05). Those with pocket guidelines were more confident treating patients with vancomycin (P<0.001), choosing initial (P=0.01) and maintenance doses (P<0.001), and knowing the monitoring frequency (P=0.03). The 85 respondents who completed the knowledge assessment scored a mean±standard deviation of 8.55±1.55 on 10 questions, and the interventions had no significant effect. CONCLUSION: Attending an educational session and possessing pocket guidelines were associated with preparedness, as measured by higher self-reported confidence using vancomycin. High knowledge scores were attained following CME; however attending an educational session or possessing pocket guidelines did not significantly increase the knowledge scores. Our findings support providing educational sessions and pocket guidelines to increase self-confidence in prescribing vancomycin, yet also highlight the importance of evaluating content, format, and delivery when seeking to improve preparedness to use vancomycin through education.

RESUMO

Randomized clinical trials and large-scale, cohort studies continue to have a critical role in generating evidence in cardiovascular medicine; however, the increasing concern is that ballooning costs threaten the clinical trial enterprise. In this Perspectives article, we discuss the changing landscape of clinical research, and clinical trials in particular, focusing on reasons for the increasing costs and inefficiencies. These reasons include excessively complex design, overly restrictive inclusion and exclusion criteria, burdensome regulations, excessive source-data verification, and concerns about the effect of clinical research conduct on workflow. Thought leaders have called on the clinical research community to consider alternative, transformative business models, including those models that focus on simplicity and leveraging of digital resources. We present some examples of innovative approaches by which some investigators have successfully conducted large-scale, clinical trials at relatively low cost. These examples include randomized registry trials, cluster-randomized trials, adaptive trials, and trials that are fully embedded within digital clinical care or administrative platforms.

RESUMO

BACKGROUND AND PURPOSE: Data monitoring committees are responsible for safeguarding the interests of study participants and assuring the integrity and credibility of clinical trials. The independence of data monitoring committees from sponsors and investigators is essential in achieving this mission. Creative approaches are needed to address ongoing and emerging challenges that potentially threaten data monitoring committees' independence and effectiveness. METHODS: An expert panel of representatives from academia, industry and government sponsors, and regulatory agencies discussed these challenges and proposed best practices and operating principles for effective functioning of contemporary data monitoring committees. RESULTS AND CONCLUSIONS: Prospective data monitoring committee members need better training. Options could include didactic instruction as well as apprenticeships to provide real-world experience. Data monitoring committee members should be protected against legal liability arising from their service. While avoiding breaches in confidentiality of interim data remains a high priority, data monitoring committees should have access to unblinded efficacy and safety data throughout the trial to enable informed judgments about risks and benefits. Because overly rigid procedures can compromise their independence, data monitoring committees should have the flexibility necessary to best fulfill their responsibilities. Data monitoring committee charters should articulate principles that guide the data monitoring committee process rather than list a rigid set of requirements. Data monitoring committees should develop their recommendations by consensus rather than through voting processes. The format for the meetings of the data monitoring committee should maintain the committee's independence and clearly establish the leadership of the data monitoring committee chair. The independent statistical group at the Statistical Data Analysis Center should have sufficient depth of knowledge about the study at hand and experience with trials in general to ensure that the data monitoring committee has access to timely, reliable, and readily interpretable insights about emerging evidence in the clinical trial. Contracts engaging data monitoring committee members for industry-sponsored trials should have language customized to the unique responsibilities of data monitoring committee members rather than use language appropriate to consultants for product development. Regulatory scientists would benefit from experiencing data monitoring committee service that does not conflict with their regulatory responsibilities.

RESUMO

OBJECTIVES: In this 2-center study, we assessed the technical feasibility and reliability of a low cost, tablet-based mobile telestroke option for ambulance transport and hypothesized that the NIH Stroke Scale (NIHSS) could be performed with similar reliability between remote and bedside examinations. METHODS: We piloted our mobile telemedicine system in 2 geographic regions, central Virginia and the San Francisco Bay Area, utilizing commercial cellular networks for videoconferencing transmission. Standardized patients portrayed scripted stroke scenarios during ambulance transport and were evaluated by independent raters comparing bedside to remote mobile telestroke assessments. We used a mixed-effects regression model to determine intraclass correlation of the NIHSS between bedside and remote examinations (95% confidence interval). RESULTS: We conducted 27 ambulance runs at both sites and successfully completed the NIHSS for all prehospital assessments without prohibitive technical interruption. The mean difference between bedside (face-to-face) and remote (video) NIHSS scores was 0.25 (1.00 to -0.50). Overall, correlation of the NIHSS between bedside and mobile telestroke assessments was 0.96 (0.92-0.98). In the mixed-effects regression model, there were no statistically significant differences accounting for method of evaluation or differences between sites. CONCLUSIONS: Utilizing a low-cost, tablet-based platform and commercial cellular networks, we can reliably perform prehospital neurologic assessments in both rural and urban settings. Further research is needed to establish the reliability and validity of prehospital mobile telestroke assessment in live patients presenting with acute neurologic symptoms.

RESUMO

This paper examines how the profile of undernutrition among children in two African countries (Ethiopia and Nigeria) changed over the period of the 2007/08 food, fuel and financial crisis. Using the Composite Index of Anthropometric Failure (CIAF), an indicator which allows for a comprehensive assessment of undernutrition in young children, we examine what changes occurred in the composition of undernutrition, and how these changes were distributed amongst children in different socio-economic groups. This is important as certain combinations of anthropometric failure (AF), especially the experience of multiple failures (dual and triple combinations of AF) are associated with higher morbidity and mortality risks, and are also related to poverty. Our hypothesis is that increases in food prices during the crisis contributed to an increase in inequality, which may have resulted in concurrent increases in the prevalence of more damaging forms of undernutrition amongst poorer children. While both countries witnessed large increases in food prices, the effects were quite different. Ethiopia managed reduce the prevalence of multiple anthropometric failure between 2005 and 2011 across most groups and regions. By contrast, in Nigeria prevalence increased between 2008 and 2013, and particularly so in the poorer, northern states. The countries studied applied quite different policies in response to food price increases, with the results from Ethiopia demonstrating that protectionist public health and nutrition interventions can mitigate the impacts of price increases on poor children.

RESUMO

BACKGROUND: The use of telemedicine in the diagnosis and treatment of acute stroke, or telestroke, is a well-accepted method of practice improving geographic disparities in timely access to neurological expertise. We propose that mobile telestroke assessment during ambulance transport is feasible using low-cost, widely available technology. MATERIALS AND METHODS: We designed a platform including a tablet-based end point, high-speed modem with commercial wireless access, external antennae, and portable mounting apparatus. Mobile connectivity testing was performed along six primary ambulance routes in a rural network. Audiovisual (AV) quality was assessed simultaneously by both an in-vehicle and an in-hospital rater using a standardized 6-point rating scale (≥4 indicating feasibility). We sought to achieve 9 min of continuous AV connectivity presumed sufficient to perform mobile telestroke assessments. RESULTS: Thirty test runs were completed: 93% achieved a minimum of 9 min of continuous video transmission with a mean mobile connectivity time of 18 min. Mean video and audio quality ratings were 4.51 (4.54 vehicle; 4.48 hospital) and 5.00 (5.13 in-vehicle; 4.87 hospital), respectively. Total initial cost of the system was $1,650 per ambulance. CONCLUSIONS: In this small, single-centered study we maintained high-quality continuous video transmission along primary ambulance corridors using a low-cost mobile telemedicine platform. The system is designed to be portable and adaptable, with generalizability for rapid assessment of emergency conditions in which direct observational exam may improve prehospital diagnosis and treatment. Thus mobile telestroke assessment is feasible using low-cost components and commercial wireless connectivity. More research is needed to demonstrate clinical reliability and efficacy in a live-patient setting.

RESUMO

BACKGROUND: We previously demonstrated that cardiovascular (CV) trials funded by the National Heart, Lung, and Blood Institute (NHLBI) were more likely to be published in a timely manner and receive high raw citation counts if they focused on clinical endpoints. We did not examine the metrics of trial reports, and our citation measures were limited by failure to account for topic-related citation behaviors. METHODS AND RESULTS: Of 244 CV trials completed between 2000 and 2011, we identified 184 whose main results were published by August 20, 2014. One investigator who was blinded to rapidity of publication and citation data read each publication and characterized it according to modified Delphi criteria. There were 46 trials (25%) that had Delphi scores of 8 or 9 (of a possible 9); these trials published faster (median time from trial completion to publication, 12.6 [interquartile range {IQR}, 6.7 to 23.3] vs. 21.8 [IQR, 12.1 to 34.9] months; P<0.01). They also had better normalized citation impact (median citation percentile for topic and date of publication, with 0 best and 100 worst, 1.92 [IQR, 0.64 to 7.83] vs. 8.41 [IQR, 1.80 to 24.75]; P=0.002). By random forest regression, we found that the 3 most important predictors of normalized citation percentile values were total costs, intention-to-treat analyses (as a modified Delphi quality measure), and focus on clinical (not surrogate) endpoints. CONCLUSIONS: NHLBI CV trials were more likely to publish results quickly and yield higher topic-normalized citation impact if they reported results according to well-defined metrics, along with focus on clinical endpoints.

RESUMO

AIM: The aim of this study was to explore lesbians' preferences when choosing obstetricians/gynecologists. MATERIAL AND METHODS: This cross-sectional study included 100 lesbian and 100 heterosexual women. A 40-item questionnaire assessed the correlation between a patient's sexual identity and her specific preferences for obstetricians/gynecologists. RESULTS: The top five most important parameters for both groups in choosing obstetricians/gynecologists overlapped greatly. Four of those were experience, ability, knowledge and personality. Only one parameter differed: lesbians ranked 'sexually tolerant' as the third most important characteristic while heterosexuals ranked 'availability' as the fifth most important characteristic. Lesbians rated 'sexual tolerance' significantly higher than heterosexuals (P < 0.001). More lesbians (56%) preferred female obstetricians/gynecologists compared to heterosexuals (21%) (P < 0.001). When compared to heterosexuals, more lesbians preferred female obstetricians/gynecologists for intimate and non-intimate procedures (P < 0.001). But within the lesbian population, a higher percentage of subjects showed a preference for female obstetricians/gynecologists only for intimate procedures. Lesbians used the following to describe their preference for female obstetricians/gynecologists: feeling more comfortable; gentle; sympathetic; patient; more understanding of women's health; better physicians in general; and more sexually tolerant (P < 0.001 vs heterosexual). However, when we looked only at the lesbian population, the majority did not exhibit a preference for a female obstetrician/gynecologist for any of these reasons. The main reason given by the 56% of the lesbians who said they prefer female obstetricians/gynecologists was feeling more comfortable. CONCLUSION: Overwhelmingly lesbians prefer sexually tolerant obstetricians/gynecologists regardless of their gender; however, only a small number of lesbian subjects in this study considered their obstetricians/gynecologists as displaying this characteristic.
