Patients’ blood pressure control and doctors’ adherence to hypertension clinical practice guideline in managing patients at health clinics in Kuala Muda district, Kedah

ABSTRACT

background: blood pressure (bP) control among Malaysian is poor and doctor’s adherence to clinical practice guideline (cPG) has been a well-known factor that may improve it. this study was designed to evaluate patients’ bP control, doctors’ adherence to the latest hypertension cPG and their association. Factors associated with bP control and cPG adherence was also examined. Methods: A cross-sectional study was conducted in Kuala Muda district’s health clinics. 331 medical records were selected using stratified random sampling and standard proforma was used for data collection. the latest edition of the Malaysian cPG on hypertension was employed to define related variables. results: A total of 160 patients (48.3%) had controlled bP and it was significantly associated with patients’ age (adjusted Odds ratio, aOr= 1.03, 95% cI 1.004, 1.05, p= 0.016) and systolic bP at presentation (aOr= 0.95, 95% cI 0.93, 0.96, p< 0.001). About 60.7% of the medical records showed doctor’s good level of cPG adherence. this adherence has significant association with presence of chronic kidney disease (aOr= 0.51, 95% cI 0.31, 0.85, p= 0.007) and cardiovascular disease (aOr= 2.68, 95% cI 1.04, 6.95, p= 0.030) in the patients and physicians’ treatment intensification (aOr= 2.00, 95% cI 1.26, 3.19, p= 0.009). However, no association was found between bP control and cPG adherence. conclusion: Hypertension control in this study was poor and the prevalence of physicians with good level of cPG adherence was slightly above average. these findings are important for relevant stakeholders to strategise an action plan to improve hypertension management outcome.
