Abstract

Background: In the time of COVID-19, various strategies are initiated by the Ministry of Health to ensure that accessibility to the way blood pressure is measured can result in inaccurate readings with huge clinical implications for management. Although several studies exist that report blood pressure variations due to measurement errors, data is lacking from sub-Saharan Africa on the proportion of inaccurate blood pressure readings. The main aim of this study was to explore the blood pressure measurement variations between routine blood pressure measurement and measurement that follows standard guidelines. Methods and Materials: We conducted an analytical cross-sectional study at Livingstone University Teaching, in Zambia and enrolled 226 persons living with HIV. Routine blood pressure measurements were repeated using standard guidelines. Descriptive and inferential statistics were used to describe and determine blood pressure differences between routine and standard measurements. Results: The median age (interquartile range) in the study was 44 (35-52) years with 149 female participants representing a female preponderance of 65.9%. Systolic and Diastolic BP were significantly different between routine and standard measurements (p<0.0001). About 23 (10%) and 59 (26%) of the participants had systolic and diastolic BP exceeding 20 mmHg and 10 mmHg, respectively. Systolic and Diastolic differences between routine and standard measurements ranged from -37 to 55 and -26 to 40, respectively. Conclusion: Our study confirms the presence of BP inaccuracy in clinical settings from a sub-Saharan African country. Knowledge and training that limits BP monitoring errors are required for health personnel attending to vulnerable groups such as PLHV where the burden of hypertension is higher than the general population. Our study highlights the need for better integration of hypertension care to HIV in clinical settings.
