De quadpil verminderde de therapeutische inertie doordat de lage dosis sneller geaccepteerd werd dan standaard monotherapie.","abstract_original":"BACKGROUND: Low-dose combinations are a promising intervention for improving blood pressure (BP) control but their effects on therapeutic inertia are uncertain. METHODS: Analysis of 591 patients randomized to an ultra-low-dose quadruple pill or initial monotherapy. The episode of therapeutic inertia was defined as a patient visit with a BP of >140/90 mm Hg without intensification of antihypertensive treatment. We compared the frequency of therapeutic inertia episodes between Quadpill and initial monotherapy as a proportion of the total population (intention-to-treat analysis with the denominator being all participants randomized) and as a proportion of people with uncontrolled BP (with the denominator being participants with uncontrolled BP). RESULTS: Therapeutic inertia occurred in fewer participants randomized to Quadpill compared with monotherapy. For example, among the 390 participants with a 6-month follow-up, therapeutic inertia according to unattended BP was 21/192 (11%) versus 45/192 (23%), P=0.002. There were similar rates of therapeutic inertia among those with uncontrolled unattended BP in each group (all P>0.4). Consistent observations were seen with the use of attended office BP measures. The major determinants of not intensifying treatment during follow-up were BP readings that were close to target and large improvements in BP compared with the previous visit. CONCLUSIONS: Among all treated individuals, low-dose Quadpill reduced the number of therapeutic inertia episodes compared with initial monotherapy. After the first follow-up visit, most high BP values did not lead to treatment intensification in both groups. Education is needed about the importance of treatment intensification despite a significant improvement in BP or BP being close to target.
