“…Although we found a high proportion of individuals with elevated blood pressure during the community screening events (NNS = 5), this was lower compared to previous studies in Lagos [1–3]. The prevalence of hypertension in Lagos is high [1,2] and we expected a high yield of participants for the pilot program through the community screening events.…”

Background: In Lagos, Nigeria, approximately 33% of the population suffers from hypertension, yet antihypertensive treatment coverage is low. To improve access to care, a decentralized pharmacy-based hypertension care model was piloted. This study reports on the recruitment strategies used and is part of a larger study to evaluate the feasibility of the care model. Objective: To describe our experience executing three different strategies to recruit hypertensive patients in the program: community hypertension screenings, hospital and pharmacy referral. Methods: Individuals with elevated blood pressure and no history of cardiovascular disease were referred to the program’s recruitment days to see a medical doctor for hypertension diagnosis and enrollment. Individuals were referred from community screenings, tertiary hospital outpatient clinics, and pharmacies participating in the program. For the community screenings, we report the number needed to screen (NNS) to find one individual with elevated blood pressure, the NNS to enroll one individual in the program, and factors associated with enrollment in the program among participants referred. Results: We recruited 226 individuals (69%) in the program via the pharmacies, 97 (30%) via the community screenings, and 2 (<1%) via hospital referral. At the community screenings 3,204 individuals participated, 729 (23%) had elevated blood pressure and 618 (85%) were eligible for referral of whom 142 (23%) visited the recruitment days, and 97 (16%) enrolled. The NNS to find one individual with elevated blood pressure was 5, and the NNS to enroll one individual was 34. Enrollment in the program was associated with advancing age, blood pressure ≥160/100 and currently using antihypertensive medication. Conclusions: Despite the potential attractiveness of community screenings to identify and refer individuals with hypertension, enrollment in the program was low. For future programs we recommend pharmacy referral as individuals seem more inclined to access care through healthcare providers they are familiar with.

“…Similarly, in Nigeria, it has been projected that the number of cases of hypertension might hit 39.1 million by 2030 going by the current trend. 21 The present study found a prevalence of hypertension of 12.6% in District Hospital Awgu in 2016. This finding is comparable with what had been previously reported for Nigeria and Eastern Nigeria by some researchers.…”

Background: Prescribing patterns in systemic hypertension vary from place to place. Studies have shown that cost could be one of the factors responsible for non-adherence to treatment among hypertensive patients. Nigerian pharmacoeconomics studies have not provided a general guide on cost-effective prescribing for hypertensive patients in the country. The aim of the study was to examine the prescribing patterns, do cost effectiveness and cost minimisation analyses of the commonly prescribed antihypertensives, and determine if cost is a major reason many of the hypertensive patients of the District Hospital are usually lost to follow up.Methods: 5267 adult (≥18 years) non-antenatal patients’ cards of 2016 were reviewed for hypertension. Examination of the prescriptions, cost-effectiveness and cost-minimisation analyses of the commonly prescribed antihypertensives were done.Results: 12.6% of the patients were hypertensive. 73% of these hypertensive patients were treated pharmacologically. 40.8% adhered to treatment. 73% of the adherent ones responded to treatment. Amlodipine was the most expensive prescribed antihypertensive (N22). Amiloride-hydrochlorothiazide with the largest cost effectiveness ratio (CER) (9) was the most cost effective of all the combinations. Lisinopril- hydrochlorothiazide (N17) was preferable to the triple combination of lisinopril-amlodipine-hydrochlorothiazide (N39), and amlodipine-hydrochlorothiazide (N32) in cost minimisation.Conclusions: Cost of drugs probably had played a significant role in non-adherence to treatment among hypertensive patients in the District Hospital in 2016, since moduretic with the largest CER (9) and nifedipine with the greatest BP reduction when combined with hydrochlorothiazide (56/22 mm Hg) were rarely prescribed.

“…In Nigeria, the estimated hypertension prevalence (systolic blood pressure (BP) ≥ 140 mmHg or diastolic BP ≥ 90 mmHg) is 28.9% among people aged 15 years and older [3]. It is well established that long-term treatment, which includes behavioral adaptations (e.g., weight control, reduced salt intake, regular exercise, smoking cessation and moderate alcohol use) and pharmacotherapy if needed, reduces BP and, concomitantly, the risk of developing CVD and other hypertension-related complications [4].…”

An estimate of the prevalence of hypertension in Nigeria

Abstract: Our findings suggest the prevalence of hypertension is high in Nigeria, and the overall awareness of raised blood pressure among hypertension cases is low in the country. We hope this study will inform appropriate public health response towards reducing this burden.
