Item Influences of community engagement and health system strengthening for cholera control in cholera reporting countries(BMJ Publishing Group, 2023-12-06) Baličević, Stephanie Ayres; Elimian, Kelly Osezele; King, Carina; Diaconu, Karin; Akande, Oluwatosin Wuraola; Ihekweazu, Vivianne; Trolle, Hanna; Gaudenzi, Giulia; Forsberg, Birger; Alfven, TobiasThe 2030 Global Task Force on Cholera Control Roadmap hinges on strengthening the implementation of multistranded cholera interventions, including community engagement and health system strengthening. However, a composite picture of specific facilitators and barriers for these interventions and any overlapping factors existing between the two, is lacking. Therefore, this study aims to address this shortcoming, focusing on cholera-reporting countries, which are disproportionately affected by cholera and may be cholera endemic. A scoping methodology was chosen to allow for iterative mapping, synthesis of the available research and to pinpoint research activity for global and local cholera policy-makers and shareholders. Using the Arksey and O’Malley framework for scoping reviews, we searched PubMed, Web of Science and CINAHL. Inclusion criteria included publication in English between 1990 and 2021 and cholera as the primary document focus in an epidemic or endemic setting. Data charting was completed through narrative descriptive and thematic analysis. Forty-four documents were included, with half relating to sub-Saharan African countries, 68% (30/44) to cholera endemic settings and 21% (9/44) to insecure settings. We identified four themes of facilitators and barriers to health systems strengthening: health system cooperation and agreement with external actors; maintaining functional capacity in the face of change; good governance, focused political will and sociopolitical influences on the cholera response and insecurity and targeted destruction. Community engagement had two themes: trust building in the health system and growing social cohesion. Insecurity and the community; cooperation and agreement; and sociopolitical influences on trust building were themes of factors acting at the interface between community engagement and health system. Given the decisive role of the community–health system interface for both sustained health system strengthening and community engagement, there is a need to advocate for conflict resolution, trust building and good governance for long-term cholera prevention and control in cholera reporting countries.Item Equity in decline: illustrating fairness in a worse-off world. [Commentary](2023-10-30) Reidpath, Daniel; Khosla, Rajat; Gruskin, Sofia; Dakessian, Arek; Allotey, PascaleItem Conflict as a macrodeterminant of non-communicable diseases: the experience of Libya.(2022-10-01) Allen, Luke N; Aghilla, Mohamed; Kak, Mohini; Loffreda, Giulia; Wild, Cervantée Erice Koorey; Hatefi, Arian; Herbst, Christopher H; El Saeh, HaiderItem The determinants of the quality of clinical management among diabetic and hypertensive patients in a context of fragility: A cross-sectional survey from Lebanon(Frontiers Media S.A., 2022-07-25) Saleh, Shadi; Muhieddine, Dina; Hamadeh, Randa; Dimassi, Hani; Diaconu, Karin; Arakelyan, Stella; Ager, Alastair; Alameddine, MohamadIntroduction: The management of NCDs is a growing challenge in low- and middle-income settings with the increasing prevalence and the associated demands that such conditions make on health systems. Fragile settings both exacerbate the risk of NCDs and undermine systems capacity. Lebanon is a setting where strategies to address rising NCDs burden have faced particularly acute contextual challenges. Methods: We conducted a cross-sectional survey with patients accessing non-communicable disease across 11 primary care centers within the Greater Beirut and Beqaa areas. Response were received from 1,700 patients. We generated a Clinical Management Index Score as a measure of quality of care, and scores related to a range of socio-demographic characteristics and other context specific variables. Results: Significantly higher clinical management index scores (better quality of care) were associated with patients living in the semi-urban/rural context of Beqaa (compared to Greater Beirut), having health insurance coverage, aged above 60, having high levels of educational attainment, and making partial or full payment for their treatment. Relatively lower index scores (poorer quality of care) were associated with Syrian nationality (compared to Lebanese) and with patients suffering from diabetes or hypertension (compared to comorbid patients). Conclusion: The study identified a wide margin for improving quality of NCDs care in fragile contexts with particular gaps identified in referral to ophthalmology, accessing all prescribed medication and receiving counseling for smoking cessation. Additionally, findings indicate a number of predictors of comparatively poor quality of care that warrant attention, notably with regard to Syrian nationality/legal status, lack of health coverage, seeking free health provision and lower educational attachment. Although these are all relevant risk factors, the findings call on donor agencies, NGOs and provider institutions to design targeted programs and activities that especially ensure equitable delivery of services to diabetic and hypertensive patients with compounded vulnerability as a result of a number of these factors.Item Estimating the contribution of transmission in primary healthcare clinics to community-wide TB disease incidence, and the impact of infection prevention and control interventions, in KwaZulu-Natal, South Africa(BMJ, 2022-04-08) McCreesh, Nicky; Karat, Aaron S.; Govender, Indira; Baisley, Kathy; Diaconu, Karin; Yates, Tom A.; Houben, Rein M. G. J.; Kielmann, Karina; Grant, Alison D.; White, RichardBackground: There is a high risk of Mycobacterium tuberculosis (Mtb) transmission in healthcare facilities in high burden settings. WHO guidelines on tuberculosis (TB) infection prevention and control (IPC) recommend a range of measures to reduce transmission in healthcare settings. These were evaluated primarily based on evidence for their effects on transmission to healthcare workers in hospitals. To estimate the overall impact of IPC interventions, it is necessary to also consider their impact on community-wide TB incidence and mortality. Methods: We developed an individual-based model of Mtb transmission in households, primary healthcare (PHC) clinics, and all other congregate settings. The model was parameterised using data from a high HIV prevalence community in South Africa, including data on social contact by setting, by sex, age, and HIV/antiretroviral therapy status; and data on TB prevalence in clinic attendees and the general population. We estimated the proportion of disease in adults that resulted from transmission in PHC clinics, and the impact of a range of IPC interventions in clinics on community-wide TB. Results: We estimate that 7.6% (plausible range 3.9%–13.9%) of non-multidrug resistant and multidrug resistant TB in adults resulted directly from transmission in PHC clinics in the community in 2019. The proportion is higher in HIV-positive people, at 9.3% (4.8%–16.8%), compared with 5.3% (2.7%–10.1%) in HIV-negative people. We estimate that IPC interventions could reduce incident TB cases in the community in 2021–2030 by 3.4%–8.0%, and deaths by 3.0%–7.2%. Conclusions: A non-trivial proportion of TB results from transmission in clinics in the study community, particularly in HIV-positive people. Implementing IPC interventions could lead to moderate reductions in disease burden. We recommend that IPC measures in clinics should be implemented for their benefits to staff and patients, but also for their likely effects on TB incidence and mortality in the surrounding community.Item Identifying key influences on antibiotic use in China: A systematic scoping review and narrative synthesis(BMJ, 2022-03-24) Coope, Caroline; Schneider, Annegret; Zhang, Tingting; Kadetz, Paul; Feng, Rui; Lambert, Helen; Wang, DeBin; Oliver, Isabel; Michie, Susan; Cabral, ChristieIntroduction: The inappropriate use of antibiotics is a key driver of antimicrobial resistance. In China, antibiotic prescribing and consumption exceed recommended levels and are relatively high internationally. Understanding the influences on antibiotic use is essential to informing effective evidence-based interventions. We conducted a scoping review to obtain an overview of empirical research about key behavioural, cultural, economic and social influences on antibiotic use in China. Methods: Searches were conducted in Econlit, Medline, PsycINFO, Social Science citation index and the Cochrane Database of Systematic Reviews for the period 2003 to early 2018. All study types were eligible including observational and intervention, qualitative and quantitative designs based in community and clinical settings. Two authors independently screened studies for inclusion. A data extraction form was developed incorporating details on study design, behaviour related to antibiotic use, influences on behaviour and information on effect (intervention studies only). Results: Intervention studies increased markedly from 2014, and largely focused on the impact of national policy and practice directives on antibiotic use in secondary and tertiary healthcare contexts in China. Most studies used pragmatic designs, such as before and after comparisons. Influences on antibiotic use clustered under four themes: antibiotic prescribing; adherence to antibiotics; self-medicating behaviour and over-the-counter sale of antibiotics. Many studies highlighted the use of antibiotics without a prescription for common infections, which was facilitated by availability of left-over medicines and procurement from local pharmacies. Conclusions: Interventions aimed at modifying antibiotic prescribing behaviour show evidence of positive impact, but further research using more robust research designs, such as randomised trials, and incorporating process evaluations is required to better assess outcomes. The effect of national policy at the primary healthcare level needs to be evaluated and further exploration of the influences on antibiotic self-medicating is required to develop interventions that tackle this behaviour.Item High-income countries remain overrepresented in highly ranked public health journals: A descriptive analysis of research settings and authorship affiliations(Taylor & Francis, 2020-02-04) Plancikova, Dominika; Duric, Predrag; O'May, FionaScientific contribution in high-impact journals is largely from authors affiliated with institutions in high-income countries (HICs). Publication of papers by contribution of individual countries to leading journals can provide a picture of the most influential countries in a particular discipline. The aim of the study was to identify changes in the patterns in authorship and origin of original research articles in relation to countries’ income level in the field of public health in 2016 in comparison to previous studies. A descriptive analysis was conducted based on articles published in highly ranked public health journals in 2016. Based on the inclusion criteria, 368 research articles were identified. Over 80% of these studies were conducted in HICs. Authors were mainly based in HICs (84%), especially in the USA. The majority of first, last, and corresponding authors were affiliated with HICs (over 90%). Our study might serve as a prompt for editorial and advisory boards of the leading international journals to provide more opportunities for researchers based in low and middle-income countries.Item Lessons learnt conducting minimally invasive autopsies in private mortuaries as part of HIV and tuberculosis research in South Africa(International Union Against Tuberculosis and Lung Disease, 2019-12-21) Karat, Aaron S.; Omar, T.; Tlali, M.; Charalambous, S.; Chihota, V. N.; Churchyard, G. J.; Fielding, K. L.; Martinson, N. A.; McCarthy, K. M.; Grant, A. D.Current estimates of the burden of tuberculosis (TB) disease and cause-specific mortality in human immunodeficiency virus (HIV) positive people rely heavily on indirect methods that are less reliable for ascertaining individual-level causes of death and on mathematical models. Minimally invasive autopsy (MIA) is useful for diagnosing infectious diseases, provides a reasonable proxy for the gold standard in cause of death ascertainment (complete diagnostic autopsy) and, used routinely, could improve cause-specific mortality estimates. From our experience in performing MIAs in HIV-positive adults in private mortuaries in South Africa (during the Lesedi Kamoso Study), we describe the challenges we faced and make recommendations for the conduct of MIA in future studies or surveillance programmes, including strategies for effective communication, approaches to obtaining informed consent, risk management for staff and efficient preparation for the procedure.Item Public health services, an essential determinant of health during crisis. Lessons from Cuba, 1989–2000(Wiley, 2012-02-01) De Vos, Pol; García‐Fariñas, Anaí; Álvarez‐Pérez, Adolfo; Rodríguez Salvá, Armando; Bonet‐Gorbea, Mariano; Van der Stuyft, PatrickDuring the 1990s, Cuba was able to overcome a severe crisis, almost without negative health impacts. This national retrospective study covering the years 1989–2000 analyses the country’s strategy through essential social, demographic, health process and health outcome indicators. Gross domestic product (GDP) diminished by 34.76% between 1989 and 1993. In 1994 slow recuperation started. During the crisis, public health expenses increased. The number of family doctors rose from 9.22 to 27.03 per 104 inhabitants between 1989 and 2000. Infant mortality rate and life expectancy exemplify a series of health indicators that continued to improve during the crisis years, whereas low birth weight and tuberculosis incidence are among the few indicators that suffered deterioration. GDP is inversely related to tuberculosis incidence, whereas the average salary is inversely related to low birth weight. Infant mortality rate has a strong negative correlation with the health expenses per inhabitant, the number of maternal homes, the number of family doctors and the proportion of pregnant women receiving care in maternal homes. Life expectancy has a strong positive correlation with health expenses, the number of nursing personnel and the number of medical contacts per inhabitant. The Cuban strategy effectively resolved health risks during the crisis. In times of serious socio‐economic constraints, a well conceptualized public health policy can play an important role in maintaining the overall well‐being of a population.Item Association between health service utilisation of internal migrant children and parents' acculturation in Guangdong, China: a cross-sectional study(BMJ Publishing Group, 2018-01-13) Peng, Bo-li; Zou, Guanyang; Chen, Wen; Lin, Yan-wei; Ling, LiObjectives To assess the health service utilisation of internal migrant children in Guangdong, China, and to explore the association between children's health service utilisation and their parents' acculturation. Design Cross-sectional survey between April and May 2016. Setting Six society-run schools of Tianhe and Baiyun districts in Guangzhou City of China. Participants We recruited all students at grade 7 or 8 and one of their parents who resided in Guangzhou over 6 months without permanent registered residence (hukou) in Guangzhou (1161 pairs completed this survey). 258 children were ill within the past 2 weeks or during the last year. Main outcome measures The main outcome was self-reported health service utilisation. Logistic regression analysis was conducted to explore the association between children's unmet needs for outpatient or inpatient service and their parents' acculturation (categorised into high, middle and low groups). Results In total, 216 children, or 18.6% of the total subjects, were ill within the past 2 weeks and were in need of outpatient service; 94 children, or 8.1% of the total subjects, were in need of inpatient service. Among them, 17.6% and 46.8% of the migrant children had unmet needs for outpatient and inpatient services, respectively. After controlling for enabling resources and predisposing characteristics, migrant children with parents in the middle-acculturation group (adjusted OR=3.17, 95% CIs 1.2 to 8.3, P<0.05) were more likely to have an unmet outpatient need than high-acculturation or low-acculturation groups, although only statistically significant when comparing with the high-acculturation group. Stratified analysis suggested that this association could be moderated by their family economic status. Conclusions Our study suggested that the association between migrant children's health service utilisation and their parents' acculturation was complex and could be moderated by family economic status. Increasing the service utilisation among migrant children requires improving the acculturation and economic status of the parents of internal migrants.
