Cohort monitoring of persons with hypertension: an illustrated example from a primary healthcare clinic for Palestine refugees in Jordan

Abstract

OBJECTIVE: Recording and reporting systems borrowed from the DOTS framework for tuberculosis control can be used to record, monitor and report on chronic disease. In a primary healthcare clinic run by UNRWA in Amman, Jordan, serving Palestine refugees with hypertension, we set out to illustrate the method of cohort reporting for persons with hypertension by presenting on quarterly and cumulative case finding, cumulative and 12-month analysis of cohort outcomes and to assess how these data may inform and improve the quality of hypertension care services. METHOD: This was a descriptive study using routine programme data collected through E-Health. RESULTS: There were 97 newly registered patients with hypertension in quarter 1, 2012, and a total of 4130 patients with hypertension ever registered since E-Health started in October 2009. By 31 March 2012, 3119 (76%) of 4130 patients were retained in care, 878 (21%) had failed to present to a healthcare worker in the last 3 months and the remainder had died, transferred out or were lost to follow-up. Cumulative and 12-month cohort outcome analysis indicated deficiencies in several components of clinical performance related to blood pressure measurements and fasting blood glucose tests to screen simultaneously for diabetes. Between 8% and 15% of patients with HT had serious complications such as cardiovascular disease and stroke. CONCLUSION: Cohort analysis is a valuable tool for the monitoring and management of non-communicable chronic diseases such as HT.
