**2.11 Adherent and non-adherent attributes**

In this study, the determination of adherence and non-adherence was done by dichotomizing whether or not nurses complied with clinical guidelines in providing healthcare services regarding hypertension follow-up care. Binary counts showing whether or not nurses made records in compliance with clinical guidelines were done using frequency statistics tables in SPSS. Based on clinical guidelines, adherence was affirmed present if at least 60% of sample records showed that nurses made records in line with guidelines. Conversely, non-adherence was affirmed if less than 60% of sample records showed that nurses made records as per the guidelines. The at least 60% threshold affirming adherence was derived from clinical guidelines. This study's results on nurses' adherence and non-adherence to guidelines are as follows:

**Adherence**: Percentages showing adherence by nurses regarding making records are as follows: Blood pressure (100%), Pulse rate (96%), Estimated glomerular filtration rate (eGFR) (70%), Cholesterol (66%) and Evaluation of oedema (64%).

**Non-adherence**: Percentages showing non-adherence by nurses regarding making records are as follows: Dyspnea (99%), Raised Jugular venous pressure (99%), Apex beat (100%) and Crepitations (83%). Number of pillows used to sleep at night (100%), Cyanosis (72%), Clubbing (72%), Chest pains (100%), (BMI) (82%), Waist circumference (100%), Blood glucose (77%), and Urine and eye tests in the

past 12 months (68% and 100% not recorded respectively). Adherence and side effects of prescribed medication were (100%) unrecorded. Smoking (90%), Alcohol

Moving onwards, the test for presence of significant association between compliance by nurses to clinical guidelines (adherence and non-adherence) and categories of attributes (physical examination, physical measurements, life-style modification, routine blood tests, and history) was done using the chi-square test at 5 percent level of significance. The Pearson chi-square value = 11.654 (p-value = 0.020) and Cramer's V score = 0.634 (p-value = 0.020) indicate presence of statistically significant and strong association between compliance outcome (adherence and nonadherence) and category of attributes. The results confirm existence of significant difference between adherence and non-adherence proportions at 5 percent level. The authors of the study conducted in Mkhondo Municipality [17] assert that the high prevalence of uncontrolled hypertension can possibly be attributed to obesity, lack of physical activity and dyslipidaemia. Moreover, the prevalence of uncontrolled hypertension and its association with low HDL-C, inadequate physical
