Prospective audit of diabetes care and outcomes in a group of geriatric French care homes.
BACKGROUND
In geriatric institutions, diabetes prevalence varies from 10 to 20%. However, little is known about patterns of care and their outcomes. To assess both, an 18-month prospective audit was conducted in 240-bed nursing and 80-bed residential care homes.


METHODS
In diabetic subjects, items of care were compared to the corresponding French guideline end-points. Dependency in activities for daily living (ADL) was evaluated at inclusion and at the end of the survey for survivors. Diabetic residents were compared to others for age, sex, mortality and one-year change of iso-resource group ranging (IRG), a need-of-care scale.


RESULTS
The 73 diabetic patients among 494 residents (14.8%) were not different from the others for age and sex (respectively age: 76.0 y +/- 7.9 compared to 78.2 y +/- 9.4; M/F sex ratio: 0.59 compared to 0.31). Oral hypoglycemic agents were prescribed in 29 (39.7%) and insulin in 26 (35.6%). Control of diabetes with HbA(1C) was in keeping with guidelines in 23.3%, HbA(1C) was never performed in 26%, and > 8% in 20.5%. Rates of items of guidelines that were never addressed ranged from 2 to 80%. During the stay, ADL dependency worsened in diabetic patients, but their one-year change in GIR range was not different from that in the others. Mortality was 30.1% compared to 37.1% in the others (NS). This mortality rate and the evolution of functional dependency were not influenced by the quality of diabetes control.


CONCLUSIONS
In these disabled elderly patients, diabetes management needs to be improved. However, mortality and the evolution of functional dependency were similar in diabetic people than in others. Interventional studies for controlling with reference to geriatric evaluation, i.e. function, nutrition and mental health, are needed in order to establish specific guidelines based on benefit-burden analysis.
