Hypertension is ranked 5th in the leading cause of mortality and 3rd leading cause of morbidity in Margosatubig. This is a before and after study, with the main objective of determining the effect of an intervention program on the level of treatment adherence among hypertensive residents in Margosatubig. It had 260 hypertensive respondents. A 3-in-1 anti-hypertensive health program focusing on knowledge, medication, and lifestyle modification was introduced. The knowledge intervention was a back-to-back calendarized trigger reminder tool and pamphlet coupled with Tele-Health Education (radio airtime). Second, in addressing medication, a proposal on referral and medication acquisition algorithm for hypertensive residents was created, submitted, and approved in coordination with the Municipal Health Officer (MHO). Third, the intervention addressing lifestyle modification included measures that focused on alcohol and smoking cessation, and salt consumption control by adopting the existing programs of the municipality. A median score of 33 and a mean score of 33.81 were computed based on the 4-point Likert scale questionnaire comprised of 13 items with a sum index range of 17 to 50. A treatment adherent respondent is determined by a mean score of 34 and above without rounding off its decimal value. The respondents were generally considered as treatment non-adherent with the computed mean score of 33.81 prior to the intervention while an improvement was noted in the level of treatment adherence of the respondents from the 1st to the 2nd Post intervention with a mean score of 34.81 and 39.07, respectively. The study concluded that the 3-in-1 anti-hypertensive intervention program brought positive significant change in the level of treatment adherence among hypertensive respondents particularly in the 1st & 2nd Post-intervention and Pre-intervention and 2nd Post-intervention.
