COMMENTARY: IMPROVING PERSISTENTLY ELEVATED HbA1c IN DIABETES MELLITUS PATIENTS IN NIGERIA

Glycated hemoglobin (HbA1c) level in patients with diabetes reflects quality of disease control and propensity to develop hyperglycemic complications. During more than 12 years of using HbA1c for monitoring of glycemic control among patients at Nigerian hospitals, the mean glycated hemoglobin ranged from 7.9% + 2.4 to 8.3% + 2.2. Most of these patients (63% to 68%) had poor glycemic controls with mean HbA1c greater than 7%. Factors that are implicated in this scenario are: 1) high cost of HbA1c testing, 2) ineffective management of risk factors, 3) poor patient compliance, 4) improperly managed diabetes education program, and 5) health care system defect. Central to improving diabetes glycemia is education of doctors, other health workers and patients, within the confines of an overhauled national health system. Physicians need to increase adherence to diabetes mellitus management guidelines and patients must be enrolled into a well-structured education program at health centers. Doctors, as leader of the health team, should drive such education schemes, which must be based on standard training curriculum, sufficient number of trained diabetes educators, and effective monitoring of patients. The most appropriate diabetes education model features small-to-moderate sized participant groups and makes use of motivational interviewing rather than a traditional advice-giving format. Improved health care funding is mandatory given the issue of cost and this can be helped by increased participation of patients in Nigeria's National Health Insurance Scheme. Failure to address the persistently elevated HbA1c will affect long-term quality of life, longevity and health care services in Nigeria.
