Longitudinal characteristics of hospital use before and after alcoholism treatment.

The frequency of inpatient hospital care for three years before and three years after alcoholism treatment was evaluated for a group of 255 patients of predominantly lower socioeconomic status treated for alcoholism at a rural midwestern medical center in 1983. Subjects were interviewed while in treatment to obtain information regarding alcoholism history and demographics. Hospital care was ascertained from an electronic data file of discharges from 172 acute care hospitals throughout the United States and Puerto Rico. One-third of the sample was never hospitalized for an alcohol-related condition in the years prior to or after alcoholism treatment, and 23% of the sample experienced no hospitalizations at all other than the treatment episode when interviewed. The majority of hospital stays before and after treatment were attributed to alcohol abuse. The frequency and total hospital length of stay for alcohol-related admissions increased yearly before treatment, peaked in the year after treatment, and then declined, but not to earliest pretreatment levels. Subjects experienced significantly more hospitalizations and length of stay after alcoholism treatment than before when comparing both the two three-year periods and the immediate 12 months before and after treatment. More frequent hospital care was also significantly associated with higher levels of daily alcohol consumption and drinking duration but not with sociodemographic indicators.
