Cohort monitoring of persons with diabetes mellitus in a primary healthcare clinic for Palestine refugees in Jordan.

To illustrate the method of cohort reporting of persons with diabetes mellitus (DM) in a primary healthcare clinic in Amman, Jordan, serving Palestine refugees with the aim of improving quality of DM care services. A descriptive study using quarterly and cumulative case findings, as well as cumulative and 12-month analyses of cohort outcomes collected through E-Health in UNRWA Nuzha Primary Health Care Clinic. There were 55 newly registered patients with DM in quarter 1, 2012, and a total of 2851 patients with DM ever registered on E-Health because this was established in 2009. By 31 March 2012, 70% of 2851 patients were alive in care, 18% 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 care: measurement of blood pressure, annual assessments for foot care and blood tests for glucose, cholesterol and renal function. 10-20% of patients with DM in the different cohorts had serious late complications such as blindness, stroke, cardiovascular disease and amputations. Cohort analysis provides data about incidence and prevalence of DM at the clinic level, clinical management performance and prevalence of serious morbidity. It needs to be more widely applied for the monitoring and management of non-communicable chronic diseases. © 2012 Blackwell Publishing Ltd.
