ObjectiveTo assess the three key issues for congenital anomalies (CAs) prevention and care, namely, CA prevalence, risk factor prevalence and survival, in a longitudinal cohort in Riyadh, Saudi Arabia.SettingTertiary care centre, Riyadh, Saudi Arabia.ParticipantsSaudi women enrolled during pregnancy over 3 years and their 28 646 eligible pregnancy outcomes (births, stillbirths and elective terminations of pregnancy for foetal anomalies). The nested case-control study evaluated the CA risk factor profile of the underlying cohort. All CA cases (1179) and unaffected controls (1262) were followed through age 2 years. Referred mothers because of foetal anomaly and mothers who delivered outside the study centre and their pregnancy outcome were excluded.Primary outcome measuresPrevalence and pattern of major CAs, frequency of CA-related risk factors and survival through age 2 years.ResultsThe birth prevalence of CAs was 412/10 000 births (95% CI 388.6 to 434.9), driven mainly by congenital heart disease (148 per 10 000) (95% CI 134 to 162), renal malformations (113, 95% CI 110 to 125), neural tube defects (19, 95% CI 25.3 to 38.3) and chromosomal anomalies (27, 95% CI 21 to 33). In this study, the burden of potentially modifiable risk factors included high rates of diabetes (7.3%, OR 1.98, 95% CI 1.04 to 2.12), maternal age >40 years (7.0%, OR 2.1, 95% CI 1.35 to 3.3), consanguinity (54.5%, OR 1.5, 95% CI 1.28 to 1.81). The mortality for live births with CAs at 2 years of age was 15.8%.ConclusionsThis study documented specific opportunities to improve primary prevention and care. Specifically, folic acid fortification (the neural tube defect prevalence was >3 times that theoretically achievable by optimal fortification), preconception diabetes screening and consanguinity-related counselling could have significant and broad health benefits in this cohort and arguably in the larger Saudi population.

ObjectiveThis study was conducted to assess current situation of medicines shortages in Pakistan and to identify its impact, reasons and possible solutions to overcome the barriers.DesignA qualitative study.SettingThe study was conducted between May 2018 and July 2018 in three cities of Pakistan including Islamabad, Karachi and Bahawalpur, depending on the availability of most relevant key informants.ParticipantsHealth regulators, pharmaceutical manufacturers, pharmaceutical distributors and pharmacists.Primary and secondary outcome measureStudy primarily explored current situation, reasons and potential solutions of medicines shortages in Pakistan. Secondary outcome was the issue of particular brand shortage.MethodSemistructured interviews were conducted. Sample size was determined by using saturation point criteria. Convenient sampling techniques were used to recruit the participants. The interviews were audiorecorded and transcribed verbatim. Data were analysed using inductive thematic analysis.ResultsA total of 41 stakeholders including 12 health regulators, 6 pharmaceutical manufacturers, 8 pharmaceutical distributors and 15 pharmacists participated in this study. Data analysis yielded 4 themes, 16 subthemes, 51 categories. Essential and life-saving medicines were in short supply. The major reasons of short supply of medicines were active pharmaceutical ingredient and raw material availability issues, lack of traditional distribution system and sudden demand fluctuation. Among proposed solutions, three most common were the facilitation and regulation of manufacturers, reasonable price fixation and improvements in the inventory control system.ConclusionMedicines were short in supply, and this may have clinical and financial impact on the patients in Pakistan. There were multiple and complex reasons of medicines shortages. Mandatory government leadership is required to resolve the issue on priority basis for improving the access of medicines to the patients.

ObjectivesTo understand patterns of subcutaneous (SC) biologics use over time in adults with inflammatory rheumatic musculoskeletal diseases receiving a homecare delivery service.DesignRetrospective cohort.SettingPatients in secondary care receiving SC biologics in the largest Scottish Health Board.ParticipantsA new bespoke cohort was created from routine data gathered as part of a health board Homecare Service Database. Patients over 18 years who received a supply of SC biologic from January 2012 to May 2015 with a diagnosis for rheumatoid arthritis (RA), psoriatic arthritis (PsA) or ankylosing spondylitis (AS) were included.Outcomes measuredA standardised framework was applied by measuring discontinuation rates, persistence using Kaplan-Meier analysis and Cox regression and adherence using medication refill adherence (MRA) and compliance rate (CR).Results751 patients were identified (AS: 105, PsA: 227, RA: 419) of whom 89.3% had more than one biologic delivery (median days’ follow-up: AS: 494; PsA: 544; RA: 529) and 83.2% did not switch biologic. For all conditions, approximately half were persistent on their index biologic (52% AS, 54% PsA, 48%RA). Of patients who discontinued treatment, the majority reinitiated with the same biologic (19% AS, 18% PsA and 21% RA). Overall adherence during the period of treatment was over 80% when calculated using MRA (median %MRA: AS: 84.0%, PsA: 85.0%, RA: 82.4%) or CR (median %CR: AS: 96.6%, PsA: 97%, RA: 96.6%).ConclusionUse of linked routine data is a sustainable pathway to enable ongoing evaluation of biologics use. A more consistent approach to studying use (discontinuation, persistence and adherence metrics) should be adopted to enable comparability of studies.

Published: September 2019

ObjectivesThe circumstances of people living in refugee camps means that they have distinct medical care requirements. Our objective is to describe clinical guidance in published WHO guidelines that refer to people living in refugee camps; and how evidence and context are used and reported in making recommendations.DesignSystematic review and analysis of WHO guidelines approved by the organisation’s quality oversight body and published between 2007 and 2018. We sought for key terms related to camps and humanitarian settings, and identified text that included guidance. We compared this to Mèdecins Sans Frontièrs (MSF) guidelines.ResultsNo WHO guideline published in the last 10 years focused exclusively on clinical guidance for healthcare in camp settings. Seven guidelines contained guidance about camps; three made recommendations for camps—but only two used formal evidence summaries. We did not find any structured consideration of the situation in camps used in the decision-making process. We examined seven WHO guidelines and six chapters within guidelines that concerned humanitarian settings: none of these documents contained recommendations based on formal evidence summaries for camp settings. One of the eight MSF guidelines was devoted to clinical care in refugees and the authors had clearly linked the health problems and recommendations to the setting, but this guideline is now >20 years old.ConclusionsThere is an absence of up-to-date, evidence-based medical treatment guidelines from WHO and MSF that comprehensively address the clinical needs for people living in camps; and there is no common framework to help guideline groups formulate recommendations in these settings. WHO may wish to consider context of special populations more formally in the evidence to decision-making approach for clinical guidelines relevant to primary care.

Published: September 2019

IntroductionThe main objective of this study is to assess the prevalence of depression at 2, 6 and 12 months postpartum in women who have had an immediate postpartum haemorrhage (PPH) (blood loss ≥500 mL within 24 hours of delivery). The secondary objectives are to assess the prevalence of anxiety and post-traumatic stress disorder among these women and to evaluate the prevalence of psychological disorders according to the severity of the PPH.Methods and analysisThis repeated, cross-sectional, single-centre study will take place at the Clermont-Ferrand University Hospital (France). The population will comprise a cohort of women giving birth at a term ≥22 weeks of gestation.For each woman with a PPH (exposed), two women without PPH (unexposed) will be included: the women who give birth immediately before and immediately after her. The PPH will be managed according to French guidelines. The principal endpoint is the prevalence of depression, measured by the Edinburgh Postnatal Depression Scale (EPDS). The intervention will consist of four surveys including various self-completed questionnaires: the first during the immediate postpartum (Post-Delivery Perceived Stress Inventory (PDPSI), Spielberger'sState-Trait Anxiety Inventory (STAI)-Y-A and Y-B and Mini-International Neuropsychiatric Interview (M.I.N.I.) 5.0.0), then at 2 months (EPDS, STAI-Y-A, Generalised Anxiety Disorder (GAD-7) and Revised Impact of Event Scale (IES-R)), and finally at 6 months and 1 year postpartum (EPDS, STAI-Y-A, GAD-7, M.I.N.I. 5.0.0 and IES-R). The study will include 1542 women — 514 with PPH.Ethics and disseminationThe institutional review board (IRB) approved the study on 14 February 2017 (IRB Sud Est VI: N°AU1243).Results will be reported in peer-reviewed journals and at scientific meetings. Findings from the study will be useful for individualising medical follow-up after childbirth, especially for woman who experienced a PPH, but also more generally in increasing birth professionals' awareness of effects of trauma. The evidence obtained might also lead to modifying practices and including this recommendation in French guidelines on PPH.Trial registration numberNCT03120208.

IntroductionAcute coronary syndrome (ACS) is one of the leading causes of death. Depression and/or anxiety after ACS is common. Studies from developed countries have reported that the occurrence of anxiety or depression after ACS might increase the risk of cardiovascular events and mortality. However, the results varied, and are limited in developing countries. Therefore, well designed large-scale real-world study is needed to make further clarification. The main objective of this study is to evaluate whether depression or anxiety could affect the prognosis of patients with percutaneous coronary intervention (PCI) post-ACS.Method and analysisThe study is a prospective, multicentre, cohort study, which will be performed at 12 large hospitals in northwest China and led by the First Affiliated Hospital of Xi'an Jiaotong University. A total of 5000 patients with PCI post-ACS will be enrolled and followed up for 2 years. Their depression and anxiety status will be evaluated with the Patient Health Questionnaire-9 or Generalised Anxiety Disorder-7 Assessment scales during the follow-up. A Cox proportional hazard model will be used to determine if depression/anxiety after PCI increase the risk of cardiovascular events. The impact of antidepression or antianxiety treatment on the cardiac prognosis will be explored as well among the patients with ACS who received the treatment after PCI.Ethics and disseminationThis study has been approved by the ethics committee of the First Affiliated Hospital of Xi'an Jiaotong University (approval number: XJTU1AF2016LSL-036). The results will be published in research articles or conference papers.Trial registration numberNCT03057691.

IntroductionThe Global Burden of Disease 2010 study ranked osteoarthritis (OA) as a leading cause of years lived with disability. With an ageing population, increasing body weight and sedentary lifestyle, a substantial increase especially in knee OA (KOA) is expected. Management strategies for KOA include non-pharmacological, pharmacological and surgical interventions. Meanwhile, over-the-counter pain medications have been discredited as they are associated with several risks with long-term usage. By consequence, the use of exercise and all sorts of complementary and alternative medicine (CAM) for joint pain has increased. The available self-management strategies are plenty, but there is no overview of their use at a population level and whether they are used along with doctors’ prescriptions or replace these. The aim of this study is to estimate the population incidence of developing knee symptoms and analyse the association between (and impact of) the use of self-reported preventive measures and knee symptoms.Methods and analysisThis prospective cohort study pragmatically recruits individuals from the municipality of Frederiksberg, Denmark. All citizens aged 60–69 years old will be contacted annually for 10 years and asked to participate in a web-based survey. The major outcomes are self-reported knee symptoms and their association with use of various management strategies, including use of non-pharmacological treatments and CAM. Secondary outcomes include the influence of treatments on use of healthcare system and surgical procedures. Descriptive and analytic statistics (eg, logistic regression) will be used to provide summaries about the sample and observations made and the associations between self-management and development of knee symptoms.Ethics and disseminationThis study can be implemented without permission from the Health Research Ethics Committee. Permission has been obtained from the Danish Data Protection Agency. Study findings will be disseminated in peer-reviewed journals and presented at relevant conferences.Trial registration numberNCT03472300.

Published: September 2019

ObjectivesTo understand how the uptake of an extended primary care service in the evenings and weekend varied by day of week and over time. Secondary objectives were to understand patient demographics of users of the service and how these varied by type of appointment and to core hour users.DesignObservational study.SettingPrimary care extended access appointments data in 13 centres in Greater Manchester, England, during 2016.ParticipantsAppointments could be booked by 1 261 326 patients registered with a family practitioner in five Clinical Commissioning Group geographic areas.Main outcome measuresPrimary outcome measure was whether an appointment was used (booked and attended), secondary outcome measures included whether used appointments were prebooked or booked the same day, and delivered by a family or nurse practitioner. Additional analyses compared patient demographics with patients reporting the use of core hour primary care services.Results65.33% of 42 472 appointments were booked and attended (used). Usage of appointments was lowest on a Sunday at 46.73% (18.07 percentage points lower usage than on Mondays (95% CI −32.46 to −3.68)). Prebooked appointments were less likely to be booked among age group 0–9 and to result in patients not attending an appointment. Family practitioner appointments were increasingly less likely to be booked with age in comparison to nurse appointments. Patients attending extended access appointments tended to be younger in comparison to core hour patients.ConclusionsThere is spare capacity in the extended access service, particularly on Sundays, suggesting reconfigurations of the service may be needed to improve efficiency of delivering the service. Patient demographics suggest the service is used by a relatively younger population than core hour services. Patient demographics varied with the types of appointment provided, these findings may help healthcare providers improve usage by tailoring appointment provision to local populations.

ObjectivesObstructive sleep apnoea (OSA) characteristics differ by gender, possibly affecting any association between OSA and dyslipidaemia. We explored whether gender influenced any association between OSA characteristics and dyslipidaemia.Methods/DesignThis was a cross-sectional, large-scale hospital-based study. Male and female risks of dyslipidaemia by OSA characteristics were assessed with logistic regression. Additive interactions were measured using three indices: the relative excess risk due to interaction, the attributable proportion due to interaction and the synergy index. Multiplicative interaction was evaluated via logistic regression.SettingA single secondary-care setting in China.Participants3760 patients with OSA.Primary and secondary outcome measuresOutcomes were male and female risks of dyslipidaemia, and the associated additive and multiplicative interactions between the apnoea–hypopnea index (AHI), the oxygen-desaturation index (ODI), the microarousal index (MAI), and gender.ResultsAfter controlling for confounding factors, males (but not females) with AHIs>30 were at higher risk of hyper-total cholesterol (TC), hypo-high-density lipoprotein cholesterol (HDL-C) status and a hyper-TC/HDL-C ratio than males with AHIs≤30. Positive additive interactions were evident between the male gender and AHI on a hyper-TC/HDL-C ratio and hypo-HDL-C status. Males with ODIs>40.1 were at higher risk of hypo-HDL-C status and a hyper-TC/HDL-C ratio than males with ODIs≤40.1. Positive additive and multiplicative interactions were evident between male gender and ODI on hyper-TC/HDL-C ratio. Males with MAIs>28.6 were at higher risk of hyper-TC and hyper-low-density lipoprotein cholesterol status than males with MAIs≤28.6, but no statistically significant interactions were apparent between gender and MAI.ConclusionsMales (but not females) with higher AHIs, ODIs or MAIs were at higher risks of some measures of dyslipidaemia. Positive interactions between male and severe OSA or intermittent hypoxia on some measures of dyslipidaemia were apparent. Thus, dyslipidaemia should be evaluated in patients with OSA, especially males with severe OSA or intermittent hypoxia.

ObjectivesKnowledge of how physical activity (PA) and sport participation are related to mental health throughout adolescence is scarce. Our objective was to describe PA levels and sport participation in a population-based sample of adolescents, and to explore how they relate to mental health in different age groups.DesignA population-based cross-sectional study.Setting and participantsThe adolescent part of the Nord-Trøndelag Health Study, a Norwegian population-based health survey, conducted from 2006 to 2008. Of 10 464 invited participants (age 13–19 years), 7619 (73%) participated, of whom 3785 (50%) were boys.Outcome measuresMental health outcomes included psychological distress assessed using a short version of the Hopkins Symptom Check List Five items, self-esteem assessed using a short version of the Rosenberg Self-Esteem Scale and life satisfaction assessed with a single-item satisfaction with life measure.MethodLogistic regression models were used to estimate the likelihood of psychological distress, low self-esteem and low life satisfaction, according to self-reported PA level and type of sport participation, stratified by gender and school level (junior vs senior high school).ResultsFewer senior high school students participated in team sports compared with junior high school students (p<0.001). Physically active adolescents and participants in team sports had higher self-esteem and life satisfaction. A high PA level, compared with a low PA level, was associated with reduced odds of psychological distress among senior high school students (OR 0.63, 95% CI 0.46 to 0.86 for girls and OR 0.46, 95% CI 0.27 to 0.79 for boys). Team sport participation was associated with reduced odds of psychological distress in senior high school girls.ConclusionA high PA level was favourably associated with various dimensions of mental health, especially for adolescents in senior high school. Team sport participation may have a positive impact on mental health and should, therefore, be encouraged.
