OBJECTIVES: Those with any psychiatric diagnosis have substantially greater rates of smoking and are less likely to quit smoking than those with no diagnosis. Using nationally representative data, we sought to provide estimates of smoking and longitudinal cessation rates by specific psychiatric diagnoses and mental health service use. DESIGN AND PARTICIPANTS: Data were analysed from a two-wave cohort survey of a US nationally representative sample (non-institutionalised adults): the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC; 2001-2002, n=43 093; 2004-2005, n=34 653). MAIN OUTCOME MEASURES: We examined smoking rates (lifetime, past year and past year heavy) and cross-sectional quit rates among those with any lifetime or past year psychiatric diagnosis (DSM-IV). Importantly, we examined longitudinal quit rates and conducted analyses by gender and age categories. RESULTS: Those with any current psychiatric diagnosis had 3.23 (95% CI 3.11 to 3.35) times greater odds of currently smoking than those with no diagnosis, and were 25% less likely to have quit by follow-up (95% CI 20% to 30%). Prevalence varied by specific diagnoses (32.4% to 66.7%) as did cessation rates (10.3% to 17.9%). Comorbid disorders were associated with higher proportions of heavy smoking. Treatment use was associated with greater prevalence of smoking and lower likelihood of cessation. CONCLUSIONS: Those with psychiatric diagnoses remained much more likely to smoke and less likely to quit, with rates varying by specific diagnosis. Our findings highlight the need to improve our ability to address smoking and psychiatric comorbidity both within and outside of healthcare settings. Such advancements will be vital to reducing mental illness-related disparities in smoking and continuing to decrease tobacco use globally. [ABSTRACT FROM AUTHOR]

Background: No data on healthcare utilisation and associated costs for the many rare entities of children's interstitial lung diseases (chILD) exist. This paper portrays healthcare utilisation structures among individuals with chILD, provides a pan-European estimate of a 3-month interval per-capita costs and delineates crucial cost drivers.Methods: Based on longitudinal healthcare resource utilisation pattern of 445 children included in the Kids Lung Register diagnosed with chILD across 10 European countries, we delineated direct medical and non-medical costs of care per 3-month interval. Country-specific utilisation patterns were assessed with a children-tailored modification of the validated FIMA questionnaire and valued by German unit costs. Costs of care and their drivers were subsequently identified via gamma-distributed generalised linear regression models.Results: During the 3 months prior to inclusion into the registry (baseline), the rate of hospital admissions and inpatient days was high. Unadjusted direct medical per capita costs (€19 818) exceeded indirect (€1 907) and direct non-medical costs (€1 125) by far. Country-specific total costs ranged from €8 713 in Italy to €28 788 in Poland. Highest expenses were caused by the disease categories 'diffuse parenchymal lung disease (DPLD)-diffuse developmental disorders' (€45 536) and 'DPLD-unclear in the non-neonate' (€47 011). During a follow-up time of up to 5 years, direct medical costs dropped, whereas indirect costs and non-medical costs remained stable.Conclusions: This is the first prospective, longitudinal study analysing healthcare resource utilisation and costs for chILD across different European countries. Our results indicate that chILD is associated with high utilisation of healthcare services, placing a substantial economic burden on health systems. [ABSTRACT FROM AUTHOR]

Background COVID-19 has had a detrimental impact on access to hip and knee arthroplasty surgery. We set out to examine whether this had a subsequent impact on preoperative opioid prescribing rates for those awaiting surgery. Methods Data regarding patient demographics and opioid utilisation were collected from the electronic health records of included patients at a large university teaching hospital. Patients on the outpatient waiting list for primary hip and knee arthroplasty as of September 2020 (COVID-19 group) were compared with historical controls (Controls) who had previously undergone surgery. A sample size calculation indicated 452 patients were required to detect a 15% difference in opioid prescription rates between groups. Results A total of 548 patients (58.2% female) were included, 260 in the COVID-19 group and 288 in the Controls. Baseline demographics were similar between the groups. For those with data available, the proportion of patients on any opioid at follow-up in the COVID-19 group was significantly higher: 55.0% (143/260) compared with 41.2% (112/272) in the Controls (p=0.002). This remained significant when adjusted for confounding (age, gender, Scottish Index of Multiple Deprivation, procedure and wait time). The proportion of patients on a strong opioid was similar (4.2% (11/260) vs 4.8% (13/272)) for COVID-19 and Controls, respectively. The median waiting time from referral to follow-up was significantly longer in the COVID-19 group compared with the Controls (455 days vs 365 days; p<0.0001). Conclusion The work provides evidence of potential for an emerging opioid problem associated with the influence of COVID-19 on elective arthroplasty services. Viable alternatives to opioid analgesia for those with end-stage arthritis should be explored, and prolonged waiting times for surgery ought to be avoided in the recovery from COVID-19 to prevent more widespread opioid use.

Background This paper describes the pilot evaluation of 'POD Adventures', a lay counsellor-guided problem-solving intervention delivered via a smartphone app in Indian secondary schools. Objective To test the feasibility and acceptability of POD Adventures for adolescents with a felt need for psychological support, and to explore the intervention's effects on self-reported mental health symptoms, prioritised problems, stress and well-being. Methods We used a mixed-methods pre-post cohort design. Participants were self-referred from grades 9-12 in two coeducational government-aided secondary schools in Goa, India. The intervention was delivered in two formats, 'mixed' (comprising individual and small group sessions) and 'group' (small group sessions only). Findings 248 participants enrolled in the study and 230 (92.7%) completed the intervention. Outcomes at 4 weeks showed significant improvements on all measures that were maintained at 12 weeks. Large effects were observed on problem severity scores (4 weeks, d=1.47; 12 weeks, d=1.53) while small to moderate effects were seen on mental health symptoms, stress and well-being. 22 students completed qualitative interviews about their experience of the intervention. Participants found POD Adventures easy to use, engaging and helpful in solving their problems. They were satisfied with the guidance provided by the counsellor irrespective of delivery format. Conclusions POD Adventures was feasible to deliver with guidance from lay counsellors in Indian schools, acceptable to participants and associated with large improvements in problem severity and mental health symptom severity. Clinical implications POD Adventures has promise as an early intervention for adolescents with a felt need for psychological support in low-resource settings. [ABSTRACT FROM AUTHOR]

The author discusses the modern perspective on a research paper titled "A prospective study of acute cerebrovascular disease in the community: the Oxfordshire Community Stroke Project, 1981—86". He comments on the paper with reference to a scale like the Glasgow Coma Scale or a technique which modified the aspects of clinical neurology like Computed Tomography brain scanning.

This supplement presents some of the methodological issues that arose during the early phases of protocol development for the National Children's Study (NCS), a probability sample of 100 000 children that will be followed prospectively from pregnancy through 21 years of age, and to share some of the challenges and solutions that were discussed. These papers on motor, social! emotional, psychiatric and neurocognitive/behavioural development do not define the protocol of the NCS, but reflect methodology related to the design of research and assessment of developmental trajectories in children that may be useful to other epidemiologists planning similar longitudinal studies.

Background Recent theorisation has pushed stigma research in new directions, arguing for a need to challenge the unequal power relations that impact groups most at risk for HIV-related stigma rather than locate stigma in the individual. Such a conceptualisation resonates with the growing emphasis on structural interventions for HIV prevention that attempt to alter the social context of risk. Methods The paper predominantly relies on longitudinal interviews conducted three times over a 2-year period with sex workers with varying degrees of involvement with the non-governmental organisation (NGO) and community-based organisation. Results Recognising that stigma is socially constructed and structurally reproduced, the NGO helped mobilise marginalised and hitherto scattered female sex workers to form community-based organisations to challenge their disadvantaged status in society. The authors show how stigma alleviation strategies presented a contradiction: emboldening one group of female sex workers to self-identify as sex workers while making others reluctant to access the intervention-run clinic. Conclusion The paper builds on a growing body of research that acknowledges the struggles in implementing structural interventions, particularly for NGOs working in regions with a diverse population of sex workers with varying needs. The authors argue that intervention goals of reducing stigma and increasing the use of sexually transmitted infection services do not have to conflict and, in fact, must go hand-in-hand for an implementation to be considered a structural intervention.

Predictive genetic testing is now routinely offered to asymptomatic adults at risk for genetic disease. However, testing of minors at risk for adult-onset conditions, where no treatment or preventive intervention exists, has evoked greater controversy and inspired a debate spanning two decades. This review aims to provide a detailed longitudinal analysis and concludes by examining the debate's current status and prospects for the future. Fifty-three relevant theoretical papers published between 1990 and December 2010 were identified, and interpretative content analysis was employed to catalogue discrete arguments within these papers. Novel conclusions were drawn from this review. While the debate's first voices were raised in opposition of testing and their arguments have retained currency over many years, arguments in favour of testing, which appeared sporadically at first, have gained momentum more recently. Most arguments on both sides are testable empirical claims, so far untested, rather than abstract ethical or philosophical positions. The dispute, therein, lies not so much in whether minors should be permitted to access predictive genetic testing but whether these empirical claims on the relative benefits or harms of testing should be assessed.

Background Previous research showed that younger adult males in the USA have, since the 1950s, died at a faster rate than females of the same age. In this paper, we quantify this difference, and explore possible explanations for the differences at different ages and in different years. Methods Using data from the Human Mortality Database (HMD), the number of additional male deaths per 10 000 female deaths was calculated for each year from 1933 to 2010, and for each year of age from 0 to 60 years, for the USA, and a number of other countries for comparison. The data were explored visually using shaded contour plots. Results Gender differences in excess mortality have increased. Coming of age (between the ages of 15 and 25 years of age) is especially perilous for men relative to women now compared with the past in the USA; the visualisations highlight this change as important. Conclusions Sex differences in mortality risks at various ages are not static. While women may today have an advantage when it comes to life expectancy, in the USA, this has greatly increased since the 1930s. Just as young adulthood for women has been made safer through safer antenatal and childbirth practices, changes in public policy can make the social environment safer for men. [ABSTRACT FROM AUTHOR]

Background Population ageing is a global challenge and understanding the dynamics of living arrangements in later life and their implications for the design of appropriate housing and long-term care is a critical policy issue. Existing research has focused on the study of transitions into residential care in the UK. This paper investigates transitions into sheltered accommodation among older people in England and Wales between 1993 and 2008. Methods The study uses longitudinal data constructed from pooled observations across waves 2-18 of the British Household Panel Survey (BHPS) data, focusing on individuals aged 65 and over who lived in private housing at baseline and who were observed for two consecutive time points. A discrete-time logistic regression model was used to examine the association of transitioning into sheltered accommodation with a range of demographic, health and socioeconomic predictors. Results Demographic (age, region), socioeconomic factors (housing tenure, having a washing machine) and contact with health professionals (number of visits to the general practitioner, start in use of health visitor) were significant determinants of an older person's move into sheltered accommodation. Conclusions Transitions into sheltered accommodation are associated with a range of demographic and socioeconomic characteristics as well as service use but not with health. Such results indicate that this type of housing option may be accessible by individuals with relatively good health, but may be limited to those who are referred by gatekeepers. Policymakers could consider making such housing option available to everyone, as well as providing incentives for building lifecourse-sensitive housing in the future. [ABSTRACT FROM AUTHOR]

Background Triage and clinical consultations increasingly occur remotely. We aimed to learn why safety incidents occur in remote encounters and how to prevent them. Setting and sample UK primary care. 95 safety incidents (complaints, settled indemnity claims and reports) involving remote interactions. Separately, 12 general practices followed 2021-2023. Methods Multimethod qualitative study. We explored causes of real safety incidents retrospectively ('Safety I' analysis). In a prospective longitudinal study, we used interviews and ethnographic observation to produce individual, organisational and system-level explanations for why safety and near-miss incidents (rarely) occurred and why they did not occur more often ('Safety II' analysis). Data were analysed thematically. An interpretive synthesis of why safety incidents occur, and why they do not occur more often, was refined following member checking with safety experts and lived experience experts. Results Safety incidents were characterised by inappropriate modality, poor rapport building, inadequate information gathering, limited clinical assessment, inappropriate pathway (eg, wrong algorithm) and inadequate attention to social circumstances. These resulted in missed, inaccurate or delayed diagnoses, underestimation of severity or urgency, delayed referral, incorrect or delayed treatment, poor safety netting and inadequate follow-up. Patients with complex pre-existing conditions, cardiac or abdominal emergencies, vague or generalised symptoms, safeguarding issues, failure to respond to previous treatment or difficulty communicating seemed especially vulnerable. General practices were facing resource constraints, understaffing and high demand. Triage and care pathways were complex, hard to navigate and involved multiple staff. In this context, patient safety often depended on individual staff taking initiative, speaking up or personalising solutions. Conclusion While safety incidents are extremely rare in remote primary care, deaths and serious harms have resulted. We offer suggestions for patient, staff and system-level mitigations.

Background Non-Hispanic Black (NHB) patients experience increased prevalence of stroke risk factors and stroke incidence compared with non-Hispanic White (NHW) patients. However, little is known about >90-day post-stroke functional outcomes following mechanical thrombectomy. Objective To describe patient characteristics, evaluate stroke risk factors, and analyze the adjusted impact of race on long-term functional outcomes to better identify and limit sources of disparity in post-stroke care. Methods We retrospectively reviewed 326 patients with ischemic stroke who underwent thrombectomy at two centers between 2019 and 2022. Race was selfreported as NHB, NHW, or non-Hispanic Other. Stroke risk factors, insurance status, procedural parameters, and post-stroke functional outcomes were collected. Good outcomes were defined as modified Rankin Scale score ≤2 and/or discharge disposition to home/self-care. To assess the impact of race on outcomes at 3-, 6-, and 12-months' follow-up, we performed univariate and multivariate logistic regression. Results Patients self-identified as NHB (42%), NHW (53%), or Other (5%). 177 (54.3%) patients were female; the median (IQR) age was 67.5 (59-77) years. The median (IQR) National Institutes of Health Stroke Scale score was 15 (10-20). On univariate analysis, NHB patients were more likely to have poor short-and long-term functional outcomes, which persisted on multivariate analysis as significant at 3 and 6 months but not at 12 months (3 months: OR=2.115, P=0.04; 6 months: OR=2.423, P=0.048; 12 months: OR=2.187, P=0.15). NHB patients were also more likely to be discharged to rehabilitation or hospice/death than NHW patients after adjusting for confounders (OR=1.940, P=0.04). Conclusions NHB patients undergoing thrombectomy for ischemic stroke experience worse 3-and 6-month functional outcomes than NHW patients after adjusting for confounders. Interestingly, this disparity was not detected at 12 months. Future research should focus on identifying social determinants in the shortterm post-stroke recovery period to improve parity in stroke care. [ABSTRACT FROM AUTHOR]

Objective: The ECG has been traditionally used to support the diagnosis of pericarditis. However, the pericardium is electrically silent and ECG changes may imply concurrent myocardial involvement rather than simple pericarditis. The aim of the present paper is to analyse the frequency, type and clinical implication of ECG changes in patients with pericarditis compared with those with myocarditis.Methods: Consecutive patients with pericarditis and/or myocarditis were included in a prospective cohort study from January 2017 to December 2020. A clinical and echocardiographic follow-up was performed at 1, 3, 6 months and then every 6 months. Cardiac magnetic resonance was used to diagnose concurrent myocarditis.Results: 166 patients (median age 47 years, 95% CI 44 to 51) with 66 men (39.8%) were included: 110 cases with pericarditis (mean age 47.7 years, 29.1% male) and 56 cases with myocarditis (mean age 44.8, 60.7% male). ECG changes were reported in 61 of 166 (36.7%) patients: 27 of 110 (24.5%) among those with pericarditis and 34 of 56 (60.7%) among those with myocarditis (p<0.0001). In multivariate logistic regression analysis, ECG changes were associated with troponin elevation (risk ratio 1.97; 95% CI 1.13 to 3.43), suggesting myocardial involvement. ECG changes were not associated with increased risk of adverse events.Conclusions: ECG changes, mainly widespread ST-segment elevation, can be recorded in about one-quarter of patients with pericarditis, and were not associated with a worse prognosis. These changes may reflect concurrent myocarditis that should be ruled out. [ABSTRACT FROM AUTHOR]

Key measures of quality of the survey data, such as retention rates and final sample sizes, are presented. Sample replenishment procedures are outlined, including the addition of a new city, Kunming, at Wave 3. Methods for constructing the longitudinal and cross-sectional survey weights are briefly described. [ABSTRACT FROM AUTHOR]

Background Little research has been done to examine whether smokers switch to illegal or roll-your-own (RYO) cigarettes in response to a change in their relative price. Objective This paper explores how relative prices between three cigarette forms (manufactured legal, manufactured illegal and RYO cigarettes) are associated with the choice of one form over another after controlling for covariates, including sociodemographic characteristics, smokers' exposure to antismoking messaging, health warning labels and tobacco marketing. Methods Generalised estimating equations were employed to analyse the association between the price ratio of two different cigarette forms and the usage of one form over the other. Findings A 10% increase in the relative price ratio of legal to RYO cigarettes is associated with a 4.6% increase in the probability of consuming RYO cigarettes over manufactured legal cigarettes (p≤0.05). In addition, more exposure to antismoking messaging is associated with a lower odds of choosing RYO cigarettes over manufactured legal cigarettes (p≤0.05). Non-significant associations exist between the manufactured illegal to legal cigarette price ratios and choosing manufactured illegal cigarettes, suggesting that smokers do not switch to manufactured illegal cigarettes as prices of legal ones increase. However, these non-significant findings may be due to lack of variation in the price ratio measures. To improve the effectiveness of increased taxes and prices in reducing smoking, policymakers need to narrow price variability in the tobacco market. Moreover, increasing antismoking messaging reduces tax avoidance in the form of switching to cheaper RYO cigarettes in Uruguay. [ABSTRACT FROM AUTHOR]

Background: The level of frailty in the older population across age cohorts and how this changes is a factor in determining future care costs and may also influence the extent of socioeconomic and gender inequalities in frailty. Methods: We model cohort-specific trajectories in frailty among the community dwelling population older than 50 years, using five waves (2002–2010) of the English Longitudinal Study of Ageing. We stratify our analysis by wealth and gender and use a frailty index, based on accumulation of ‘deficits’. Results: For males and females between the ages of 50 and 70 in 2002, frailty trajectories for adjacent age cohorts converge. However, levels of frailty are higher in recent compared with earlier cohorts at the older ages (for cohorts aged over 70 in 2002). These cohort differences are largest in the poorest wealth group, while for the most affluent, frailty trajectories overlap across all adjacent cohorts suggesting no change across cohorts. Conclusions: A key driver of the cohort differences in frailty that we observe is likely to be increased survival of frail individuals. Importantly, this paper illustrates that the social conditions experienced across the wealth distribution impacts on the rate of deficit accumulation in older populations. Our results on trajectories of frailty between 2002 and 2010 are pessimistic and, in the context of rising life expectancies, suggest that poorer older people in particular spend additional years of life in a frail state.

Background While an association has been established between low income and poor diet using cross-sectional data, such analysis cannot account for confounding by unobserved characteristics correlated with income and diet, and changes in income and diet cannot be tracked over time. This paper, using longitudinal panel data, explores whether falls in objective and subjective family income predict deterioration in children's diets over time. Methods This paper uses panel data from the nationally representative birth cohort study Growing Up in Scotland. 3279 families have valid data on all dependent, independent and control variables for both time points. Dietary data were collected using maternal recall at sweeps 2 and 5 when the children were aged 22 and 58 months, respectively. Mothers reported on children's variety of consumption of vegetables, fruit and on the frequency of consumption of crisps, sweets and sugary drinks. The dietary variables were ordinal and were analysed using multivariate fixed effects ordinal logistic regression models. Results Controlling for time-varying confounders (children's food fussiness, maternal social class, maternal education, family composition, maternal employment) and for family and child time-invariant characteristics, moving from the highest to the lowest income band was linked to a smaller chance of increased fruit variety from 22 to 58 months (OR=0.42, 95% CI 0.21 to 0.82). Mothers who transitioned from 'living very comfortably' to 'finding it very difficult' to cope on current income had children who consumed fewer fruit varieties over time (OR=0.40, 95% CI 0.19 to 0.85), and who increased their frequency of consumption of crisps (OR=2.03, 95% CI 1.05 to 3.94) and sweets (OR=2.23, 95% CI 1.18 to 4.20). Conclusions The diets of young children in Scotland deteriorated between the ages of 2 and 5 years across the entire socioeconomic spectrum. Additionally, deterioration in subjective income predicted less healthy diets for children. [ABSTRACT FROM AUTHOR]

Background: In sport injury epidemiology research, the injury incidence rate (IR) is defined as the number of injuries over a given length of participation time (exposure, eg, game hours). However, it is common that individual weekly exposure is missing due to requirements of personnel at every game to record exposure information. Ignoring this issue will lead to an inflated injury rate because the total exposure serves as the denominator of IR, where the number of injury cases were captured accurately. Purpose: This paper used data collected from a large community cohort study in youth ice hockey as an example, and compared six methods to handle missing weekly exposure of individual players. Methods: The six methods to handle missing weekly exposures include available case analysis, last observation carried forward, mean imputation, multiple imputation, bootstrapping and best/worst case analysis. To estimate injury rate ratios (IRRs) between Alberta and Quebec, as in the original study, three statistical models were applied to the imputed datasets: Poisson, zeroinflated Poisson and negative binomial regression models. Results: The final sample for imputation included 2098 players for whom 12.5% of weekly game hours were missing. Estimated IRs and IRRs with CIs from different imputation methods were similar when the proportion of missing was small. Simulations showed that mean and multiple imputations provide the least biased estimates of IRR when the proportion of missing was large. Conclusions: Complicated methods, like multiple imputation or bootstrap, are not superior over the mean imputation, a much simpler method, in handling missing weekly exposure of injury data where exposures were missing at random.

Objective: To review systematically the frequency and prognostic significance of vitreous haemorrhage in patients with subarachnoid haemorrhage (Terson's syndrome).Methods: Papers relating to vitreous haemorrhage in patients with subarachnoid haemorrhage were retrieved. The only studies considered were those with at least 10 consecutive cases of subarachnoid haemorrhage with or without vitreous haemorrhage. The frequency of vitreous haemorrhage in such cases was calculated in prospective and retrospective studies. Mortality was compared in patients with and without Terson's syndrome.Results: 154 papers were reviewed. Three prospective studies and six retrospective studies satisfied the inclusion criteria. Of 181 patients with subarachnoid haemorrhage assessed prospectively (mean age, 51.7 years), 24 (13%) had vitreous haemorrhage; among 1086 retrospective records, 37 (3%) had documented vitreous haemorrhage (p<0.001). Patients with Terson's syndrome had higher Hunt and Hess grades than those without (mean grade, 3.6 v 2.6). Patients with Terson's syndrome were also more likely to die (13 of 30 (43%) v 31 of 342 (9%); odds ratio 4.8; p<0.001).Conclusions: Prospective studies show a higher frequency of Terson's syndrome than retrospective studies, suggesting that vitreous haemorrhage is not well documented. Vitreous haemorrhage is an adverse prognostic finding in patients with subarachnoid haemorrhage. [ABSTRACT FROM AUTHOR]

Background The Neqstent coil-assisted flow diverter (NQS) is a neck bridging device to facilitate coil occlusion of intracranial aneurysms. CAFI is a prospective, single-arm, multicenter study on the safety and performance of the NQS adjunctive therapy device together with platinum coils for treatment of unruptured intracranial aneurysms. Methods Thirty-eight patients were enrolled. Primary endpoints were occlusion at 6 months for efficacy, and any major stroke or non-accidental death up to 30 days or major disabling stroke within 6 months for safety. Secondary endpoints were re-treatment rate, procedure time, and procedure/device-related adverse events. Procedural and follow-up imaging was reviewed by an independent core laboratory. Adverse events were reviewed and adjudicated by a clinical events committee. Results The NQS was successfully implanted in 36/38 aneurysms, 2/38 in the intention-to-treat group did not receive a NQS and were excluded from follow-up after 30 days. In the per protocol group (PP), 33/36 patients were available for angiographic follow-up. Device related adverse events were recorded in 4/38 (10.5%) patients, one hemorrhagic and three thromboembolic. In the PP group, immediate post-treatment adequate occlusion (RR1 and RR2) was seen in 9/36 (25%) and progressed to 28/36 (77.8%) at 6 months. Complete occlusion (RR1) was achieved in 29/36 (80.6%) at the last available angiogram (3/36 were post procedure). The mean procedure time was 129 min (50-300 min, median 120 min). Conclusion The NQS in conjunction with coils appears to be effective in the treatment of intracranial wide-neck bifurcation aneurysms, but its safety remains to be proved in larger series.

Purpose of study Initiatives to standardise hospital paper-based prescription charts are underway in various countries in an effort to reduce prescribing errors. The aim of this study was to investigate the extent to which prescribing error rates are influenced by prescription chart design and familiarity. Study design In this prospective, randomised, cross-over study, Foundation Year 1 doctors working in five Scottish National Health Service (NHS) Boards participated in study sessions during which they were asked to prescribe lists of medications for five fictional patients using a different design of paper prescription chart for each patient. Each doctor was timed completing each set of prescriptions, and each chart was subsequently assessed against a predefined list of possible errors. A mixed modelling approach using three levels of variables (design of and familiarity with a chart, prescribing speed and individual prescriber) was employed. Results A total of 72 Foundation Year 1 doctors participated in 10 data-collection sessions. Differences in prescription chart design were associated with significant variations in the rates of prescribing error. The charts from NHS Highland and NHS Grampian produced significantly higher error rates than the other three charts. Participants who took longer to complete their prescriptions made significantly fewer errors, but familiarity with a chart did not predict error rate. Conclusions This study has important implications for prescription chart design and prescribing education. The inverse relationship between the time taken to complete a prescribing task and the rate of error emphasises the importance of attention to detail and workload as factors in error causation. Further work is required to identify the characteristics of prescription charts that are protective against errors. [ABSTRACT FROM AUTHOR]

Background Community mobilisation interventions for HIV prevention among female sex workers (FSWs) aim to organise FSWs for collective action and challenge the structures of power that underlie HIV risk. Assessing intervention impact is challenging because the importance of direct individual exposure to intervention components may decrease over time as change occurs at social-normative, policy and other structural levels. In this paper, the authors examine changes over time in consistent condom use among FSWs in Rajahmundry, Andhra Pradesh, the location of a long-standing community mobilisation intervention. Methods The authors analyse cross-sectional data collected among FSWs at three time points (n=2276) using respondent-driven sampling. Multiple logistic regression was used to assess the association of programme exposure with consistent condom use and whether this association varied over time. Results The proportion of FSWs having no exposure or only receptive exposure to the intervention decreased over time, while active utilisation increased from 19.4% in 2006 to 48.5% in 2009-2010. Consistent condom use with clients also increased from 56.3% in 2006 to 75.3% in 2009-2010. Multivariate analysis showed that age, age at start of sex work, venue, living conditions and programme exposure were significantly associated with condom use. The positive association between programme exposure and consistent condom use did not vary significantly over time. Conclusions Findings indicate improvements in HIV risk reduction behaviour among FSWs and suggest that the intervention has substantial reach in the FSW population. The intervention's strategies may be contributing to population-level HIV risk reduction among FSWs. [ABSTRACT FROM AUTHOR]

ABSTRACT:This paper estimates the incidence (all ages) of spinal cord neurological impairment (SCI; traumatic and non traumatic) in New Zealand and describes pre-SCI characteristics and early post-SCI outcomes for participants (16-64 years) in this longitudinal study. Demographic and clinical data on all people admitted to New Zealand's two spinal units (mid-2007 to mid-2009 )were included for the estimate of incidence. Participants in this longitudinal study were asked at first interview about pre-SCI socio-demographic, health and behavioural characteristics, and about post-SCI symptoms, general health status (EQ-5D) and disability (WHODAS 12-item). Age-adjusted incidence rates (95% CI) for European,Maori, Pacific and 'Other' ethnicities were 29 (24-34), 46 (30-64), 70 (40-100) and 16 (9-22) per million, respectively. Interviews with 118 (73%) participants (16-64 years), occurred 6.5 months post-SCI. Most reported bother with symptoms, and problems with health status and disability. Compared with Europeans, the incidence of SCI is high among Maori and particularly high among Pacific people. Six months after SCI, proximate to discharge from the spinal units, considerable symptomatic, general health and disability burden was borne by people with SCI. [ABSTRACT FROM AUTHOR]
