Abstract
The objective of this study was to test the effectiveness of an educational intervention with use of educational technology (flipchart) to promote quality of life (QOL) and treatment adherence in people with hypertension. It was an intervention study of before-and-after type conducted with 116 hypertensive people registered in Primary Health Care Units. The educational interventions were conducted using the flipchart educational technology. Quality of life was assessed through the MINICHAL (lowest score = better QOL) and the QATSH (higher score = better adherence) was used to assess the adherence to hypertension treatment. Both were measured before and after applying the intervention. In the analysis, we used the Student’s t-test for paired data. The average baseline quality of life was 11.66 ± 7.55, and 7.71 ± 5.72 two months after the intervention, showing a statistically significant reduction (p <0.001) and mean of differences of 3.95. The average baseline adherence to treatment was 98.03 ± 7.08 and 100.71 ± 6.88 two months after the intervention, which is statistically significant (p < 0.001), and mean of differences of 2.68. The conclusion was that the educational intervention using the flipchart improved the total score of quality of life in the scores of physical and mental domains, and increased adherence to hypertension treatment in people with the disease.
Highlights
Hypertension is a multifactorial clinical condition characterized by high and sustained levels of blood pressure, when systolic pressure is ! 140mmHg and diastolic pressure is ! 90mmHg
The Questionnaire on Adherence to Systemic Hypertension Treatment (QATSH) is a questionnaire developed by Rodrigues [17] in his doctoral thesis entitled ‘Adherence to hypertension treatment: development of an assessment instrument based on Item Response Theory (IRT)’
The educational intervention using the flipchart for the group of hypertensive people was associated with the reduction of systolic blood pressure
Summary
Hypertension is a multifactorial clinical condition characterized by high and sustained levels of blood pressure, when systolic pressure is ! 140mmHg and diastolic pressure is ! 90mmHg. Hypertension is a multifactorial clinical condition characterized by high and sustained levels of blood pressure, when systolic pressure is ! 90mmHg. The blood pressure can be classified as optimal, normal, high-normal, stage 1 hypertension, stage 2 hypertension, stage 3 hypertension and isolated systolic hypertension [1]. The disease prevalence among adults is 25% worldwide and the estimate for 2025 is 29% [2]. The control of blood pressure levels and of the disease, can be effective with non-pharmacological antihypertensive treatment (in association with drugs or not), and improve the lives of hypertensive people. Despite the evidence that antihypertensive treatment significantly reduces cardiovascular morbidity and mortality, the inadequate disease control has been observed in several countries [4,5,6,7]
