  1. Drug disorders and cardiovascular disease : the impact on annual hospital length of stay for the medicare population.

    Article - En anglais

    We studied 3,942,868 Medicare patients (comprised of elderly and disabled) discharged with cardiovascular disease (CVD) during 1987, of which 41,095 (1%) had a drug disorder.

    Among this small subgroup, the percent of those overlapping with an alcohol and/or mental disorder is 33% for the elderly and 47% for the disabled.

    The presence of a drug disorder discharge diagnosis is associated with an excess of 329,650 days of hospital care and $174,498,071 in hospital charges as illustrated by a 51% increase in average annual days in the hospital for the elderly, and a similar 61% increase for the disabled.

    The concomitant increase in average annual discharges offers an explanation.

    Clinical progression in drug disorder severity (six categories were defined) is associated with increasing lengths of stay ; for example, drug dependence comorbidities present longer lengths of stay than drug abuse comorbidities.

    Among the 12 categories of CVD defined, patients with rheumatic heart disease, hypertensive heart disease, hypertension, and other venous disorders were those whose length of stay experienced the largest percent increase when a drug disorder was present.

    When drug disorders compete with alcohol and/or mental disorders in a general linear model predicting average annual length of stay, they remain significant at the p<. 001 level.
