Evaluation of workplace hypertension preventative and detection service in a Ghanaian University

Abstract

Objectives: This study sought to evaluate the effectiveness of a pharmacist-led hypertension screening, preventative and detection services at the workplace.

Methods: This was a prospective study conducted among staff at the Kwame Nkrumah University of Science and Technology from September 2019 to September 2020. Staff were screened for hypertension and interviewed via a structured questionnaire to gather data on their lifestyle practices and risk of hypertension. Prehypertensive individuals were educated and followed up for 6 months and all participants who had blood pressure consistently above 140/90 mmHg (hypertension) were referred to the University Hospital.

Key findings: Out of 162 participants screened, 19 (11.7%) were classified as stage 1 hypertensive, 5 (3.1%) as stage 2 hypertensive and 74 (45.7%) as prehypertensive. The commonest modifiable risk factor identified was body mass index > 25 kg/m2 (99, 61.1%) and physical inactivity (97, 59.9%). Eleven (61%) out of 18 participants referred to the physician were confirmed hypertensive and prescribed medications. After a 6 month follow-up, there was a reduction in the mean systolic and diastolic blood pressures (P < 0.05); and 47 (63.5%) out of 74 initially classified as prehypertensive had their blood pressures within the normal range.

Conclusion: Workplace preventative and detection services can effectively lead to the identification of risk factors, promotion of lifestyle changes and detection of hypertension. Such services should be integrated into workplace systems to aid the prevention and detection of chronic conditions such as hypertension.
