Diabetic patients on dialysis: a changing picture.
Prevalence of diabetic patients on dialysis is often considered a marker of overall acceptance rate for dialysis; however, even when acceptance policy is open, incidence of diabetic patients varies widely. Epidemiological differences of diabetes incidence all over the world partly explain the discrepancies. Incidence of diabetic patients accepted for dialysis (1981 to 82: 6 p.m.p.; 1989 to 90: 11.5 p.m.p.) differs according to age and sex in the setting analyzed (Piedmont, Northern Italian region, about 4,400,000 inhabitants, 20 dialysis centers, open acceptance since the mid-70s, yearly information on 100% of patients, gathered by a Dialysis and Transplantation Registry). Patterns changed remarkably during the 10 years considered (1981 to 90). Incidence was higher in males (10.4 p.m.p. in the period 1981 to 90), with a peak at ages 60 to 69. Incidence remained relatively stable in the younger patients, but increased in the elderly, mainly in males, rising from 6.23 in 1981 to 82 to 12.88 p.m.p. in 1989 to 90 (males, all ages). In conclusion, the demographic characteristics of diabetic patients with ESRD accepted for dialysis is changing. The stability of incidence of younger patients reassures about the open acceptance policy, at least in these ages. The increase in the elderly probably reflects the longer lifespan of diabetic patients in the overall population. The possibility of a hidden preselection must be further assessed. Future provisions of dialysis needs must take into account the trend towards an increase of this high risk, elderly population.
