Glucose control in acutely ill patients: a survey of Israeli internal medicine departments.

ABSTRACT

BACKGROUND: Tight glucose control has been shown to improve the outcome of patients with severe acute illnesses who are hospitalized in intensive care units and on intravenous insulin-based regimens. OBJECTIVES: To clarify the attitudes of internists towards tight control of glucose levels in acutely ill patients hospitalized in general medical wards. METHODS: A questionnaire on intensive glucose control in acutely ill patients hospitalized in medical wards was mailed to each of the 100 heads of internal medicine departments in Israel. RESULTS: Fifty physicians responded. Of these, 80% considered tight glucose control to be a major treatment target, but only two-thirds had defined it as a goal in their ward. Furthermore, only about half had a defined protocol for such an intervention. Most physicians considered patients with acute coronary syndrome, stroke and infectious diseases as candidates for a tight glucose control protocol. The most frequently used modalities were multiple blood glucose measurements and repeated injections of short-acting subcutaneous insulin. The main reasons given for not having a defined protocol were lack of guidelines, no evidence of a clear benefit during hospitalization on a medical ward, and a shortage of adequately trained staff. CONCLUSIONS: Inconsistencies in physicians' attitudes and in treatment protocols regarding tight control of glucose levels in acutely ill patients hospitalized on a medical ward need to be addressed. Evaluation of the feasibility, effectiveness and side effects of a defined protocol is needed before any regimen can be approved by the heads of the internal medicine departments.
