Blood pressure screening in Mozambique: the May Measurement Month 2017 project-Sub-Saharan Africa

Elevated blood pressure (BP) is a growing burden worldwide, leading to over 10 million deaths each year. In Mozambique, two national surveys of risk factors for chronic diseases were done, using the WHO STEPWISE approach, the first in 2005 and the last in 2014/2015. In this period of 10 years, the prevalence of hypertension in the adult population increased from 33.1% to 38.9% and the extremely low levels of awareness, treatment, and control did not change significantly. May Measurement Month (MMM) is a global initiative of the International Society of Hypertension aimed at raising awareness of high BP and to act as a temporary solution to the lack of screening programmes worldwide. An opportunistic cross-sectional survey of volunteers aged ≥18 years was carried out in May 2017. Blood pressure measurement, the definition of hypertension and statistical analysis followed the standard MMM protocol. Screening was conducted by volunteers, mainly in work places, markets, and religious activities, in the capital city, in most of the provincial capitals and some rural districts. About 4454 individuals were screened with a mean age of 39 years, and, after multiple imputation, 1371 (31.1%) had hypertension. Of individuals not receiving anti-hypertensive medication, 1099 (26.6%) were hypertensive. Of individuals receiving antihypertensive medication, 166 (61.6%) had uncontrolled BP. MMM17 was the largest BP screening campaign undertaken in Mozambique. These results suggest that opportunistic screening is an important tool to identify significant numbers of patients with raised BP

Practice patterns and outcomes after stroke across countries at different economic levels (INTERSTROKE):an international observational study

Background: Stroke disproportionately affects people in low-income and middle-income countries. Although improvements in stroke care and outcomes have been reported in high-income countries, little is known about practice and outcomes in low and middle-income countries. We aimed to compare patterns of care available and their association with patient outcomes across countries at different economic levels. Methods: We studied the patterns and effect of practice variations (ie, treatments used and access to services) among participants in the INTERSTROKE study, an international observational study that enrolled 13 447 stroke patients from 142 clinical sites in 32 countries between Jan 11, 2007, and Aug 8, 2015. We supplemented patient data with a questionnaire about health-care and stroke service facilities at all participating hospitals. Using univariate and multivariate regression analyses to account for patient casemix and service clustering, we estimated the association between services available, treatments given, and patient outcomes (death or dependency) at 1 month. Findings: We obtained full information for 12 342 (92%) of 13 447 INTERSTROKE patients, from 108 hospitals in 28 countries; 2576 from 38 hospitals in ten high-income countries and 9766 from 70 hospitals in 18 low and middle-income countries. Patients in low-income and middle-income countries more often had severe strokes, intracerebral haemorrhage, poorer access to services, and used fewer investigations and treatments (p<0·0001) than those in high-income countries, although only differences in patient characteristics explained the poorer clinical outcomes in low and middle-income countries. However across all countries, irrespective of economic level, access to a stroke unit was associated with improved use of investigations and treatments, access to other rehabilitation services, and improved survival without severe dependency (odds ratio [OR] 1·29; 95% CI 1·14–1·44; all p<0·0001), which was independent of patient casemix characteristics and other measures of care. Use of acute antiplatelet treatment was associated with improved survival (1·39; 1·12–1·72) irrespective of other patient and service characteristics. Interpretation: Evidence-based treatments, diagnostics, and stroke units were less commonly available or used in low and middle-income countries. Access to stroke units and appropriate use of antiplatelet treatment were associated with improved recovery. Improved care and facilities in low-income and middle-income countries are essential to improve outcomes
