Evidence from clinical practice and from the literature suggest that approximately half of most common chronic disorders are undetected, that half of those detected are not treated, and that half of those treated are not controlled: the ‘rule of halves’. Workload in primary care would increase by at least 12% if all common and important chronic disorders were fully diagnosed, treated and followed up; the accompanying effects on prescribing costs would be complex, but not necessarily inflationary.
Objective: The aim of the present study was to assess the applicability of the rule of halves in a rural adult population in Komerika to evaluate its relevance in establishing levels of awareness, thus control of hypertension in general population.
Materials and Methods: A cross ‑sectional community survey was done to include 105 men and 145 women aged >20 years of age in Komerika, Nellore district. Hypertension was assessed using standardized recording, structured schedule on diagnosis and antihypertensive drug treatment according to The Indian hypertension guidelines for High Blood Pressure by the PHC medical officer.
Results: The overall prevalence of hypertension in this population was 42.41% (106/250). Of these 106 individuals with hypertension, only 62 (58.49%) were known hypertensive’s. Of the 62 known hypertensives, 42 subjects (67.74%) were under any kind of antihypertensive therapy. Of these 42 individuals, only 11 (26.19%) had blood pressure under control.
Conclusion: The ‘rule of halves’ when taken as a standard of measurement showed that the studied population had poor awareness, comparatively better treatment and inadequate control of Hypertension. Thus, there is a need to effectively combat the burden of hypertension in this population of Komerika.
