Abstract: Cardiovascular research output and citations of publications from Africa have historically been low yet may be increasing. However, data from the continent are limited. To evaluate the cardiovascular research output and citations from 52 African countries between 1999 and 2008, we created a bibliometric filter to capture cardiovascular research articles published in the Web of Knowledge based on specialist journals and title words. Two coauthors with expertise in cardiovascular medicine tested and refined this filter to achieve % precision and recall. We matched retrieved records with their associated citation reports and calculated the running 5‐year citation count postpublication, including the year of publication. Publications from Africa were identified by author addresses. South Africa published 872 cardiovascular research papers, Egypt 393, Tunisia 264, and Nigeria 192 between 1999 and 2008. The number of publications increased over the time period for a small number of countries (range 0.1 to 4.8 more publications per year by fractional count). Most countries' citations were low ( ), but citations were greatest for South Africa (7063), Egypt (2557), Tunisia (903), and Nigeria (540). The same countries had the greatest annual increase in 5‐year citation index values: 65 (95% CI : 30, 99) for South Africa, 46 (34, 58) for Egypt, 22 (15, 28) for Tunisia, and 8 (2, 14) for Nigeria. The burden of cardiovascular disease had a weak and inconsistent relationship to cardiovascular publications ( r 2 =0.07, P =0.05). Greater gross domestic product was associated with more cardiovascular publications in 2008 ( r 2 =0.53, P .0001). The increases in cardiovascular research outputs from Africa are concentrated in a few countries. The reasons for regional differences in research outputs require further investigation, particularly relative to competing disease burdens. Higher prioritization of cardiovascular research funding from African countries is warranted.

Abstract: India has high prevalence of hypertension but low awareness, treatment and control rate. A cluster randomised trial entitled ‘m-Power Heart Project’ is being implemented to test the effectiveness of a nurse care coordinator (NCC) led complex intervention to address uncontrolled hypertension in the community health centres (CHCs). The trial’s process evaluation will assess the fidelity and quality of implementation, clarify the causal mechanisms and identify the contextual factors associated with variation in the outcomes. The trial will use a theory-based mixed-methods process evaluation, guided by the Consolidated Framework for Implementation Research. The process evaluation will be conducted in the CHCs of Visakhapatnam (southern India). The key stakeholders involved in the intervention development and implementation will be included as participants. In-depth interviews will be conducted with intervention developers, doctors, NCCs and health department officials and focus groups with patients and their caregivers. NCC training will be evaluated using Kirkpatrick’s model for training evaluation. Key process evaluation indicators (number of patients recruited and retained concordance between the treatment plans generated by the electronic decision support system and treatment prescribed by the doctor and so on) will be assessed. Fidelity will be assessed using Borrelli et al ’s framework. Qualitative data will be analysed using the template analysis technique. Quantitative data will be summarised as medians (IQR), means (SD) and proportions as appropriate. Mixed-methods analysis will be conducted to assess if the variation in the mean reduction of systolic blood pressure between the intervention CHCs is influenced by patient satisfaction, training outcome, attitude of doctors, patients and NCCs about the intervention, process indicators etc. Ethical approval for this study was obtained from the ethics committees at Public Health Foundation of India and Deakin University. Findings will be disseminated via peer-reviewed publications, national and international conference presentations. NCT03164317 Pre-results.

Abstract: In rural areas in China and India, the cardiovascular disease burden is high but economic and healthcare resources are limited. This study (the Simplified Cardiovascular Management Study [SimCard]) aims to develop and evaluate a simplified cardiovascular management program delivered by community health workers with the aid of a smartphone-based electronic decision support system. The SimCard study was a yearlong cluster-randomized, controlled trial conducted in 47 villages (27 in China and 20 in India). Recruited for the study were 2086 in iduals with high cardiovascular risk (aged ≥40 years with self-reported history of coronary heart disease, stroke, diabetes mellitus, and/or measured systolic blood pressure ≥160 mm Hg). Participants in the intervention villages were managed by community health workers through an Android-powered app on a monthly basis focusing on 2 medication use and 2 lifestyle modifications. In comparison with the control group, the intervention group had a 25.5% ( P .001) higher net increase in the primary outcome of the proportion of patient-reported antihypertensive medication use pre- and post-intervention. There were also significant differences in certain secondary outcomes: aspirin use (net difference: 17.1% P .001) and systolic blood pressure (–2.7 mm Hg P =0.04). However, no significant changes were observed in the lifestyle factors. The intervention was culturally tailored, and country-specific results revealed important differences between the regions. The results indicate that the simplified cardiovascular management program improved quality of primary care and clinical outcomes in resource-poor settings in China and India. Larger trials in more places are needed to ascertain the potential impacts on mortality and morbidity outcomes. URL: www.clinicaltrials.gov . Unique identifier: NCT01503814.
