The feedback between monitoring and improvement of quality of diabetes care.

The need for permanent, population-wide, improvement in metabolic care of diabetic patients is generally accepted. This paper highlights some related aspects which must be considered by any health care provider: (1) Monitoring metabolic or other variables in diabetic patients is an essential tool in routine metabolic care, where a "short feedback" between monitored data and medical or behavioral measures is permanently established by the patients themselves, the physicians, the nurses etc. (2) Quality insurance requires the closure of a "long feedback" between informations and interventions, such as conditions, tools, methods, used at the different levels of the care system, from the individual patient to a population scale. (3) Appropriate epidemiological studies are required to program and evaluate the effect of any activity aimed at insuring and maybe improving the quality of care of diabetic patients, especially if one considers the time required to reach "hard end-points" such as the evaluation of patient mortality or the outcome of children from diabetic mothers. (4) The knowledge of incidence and prevalence rates of diabetes and its complications, and of risk factors may stimulate the political and economical recognition of the importance of the disease by health care officials. (5) In this way, the medical recognition is also stimulated within the professional team responsible for the establishment of the "long feedback" of quality insurance at the level of a given method, of an individual patient or of a health care unit, and for the actual implementation of generally accepted knowledge, everywhere in routine care.
