Adverse drug events in hospitalized patients : Excess length of stay, extra costs, and attributable mortality.
- To determine the excess length of stay, extra costs, and mortality attributable to adverse drug events (ADEs) in hospitalized patients.
- Matched case-control study.
- The LDS Hospital, a tertiary care health care institution.
- All patients admitted to LDS Hospital from January 1,1990, to December 31,1993, were eligible.
Cases were defined as patients with ADEs that occurred during hospitalization ; controls were selected according to matching variables in a stepwise fashion.
- Controls were matched to cases on primary discharge diagnosis related group (DRG), age, sex, acuity, and year of admission ; varying numbers of controls were matched to each case.
Matching was successful for 71% of the cases, leading to 1580 cases and 20197 controls.
Main Outcome Measures
- Crude and attributable mortality, crude and attributable length of stay, and cost of hospitalization.
- ADEs complicated 2.43 per 100 admissions to the LDS Hospital during the study period.
The crude mortality rates for the cases and matched controls were 3.5% and 1.05%, respectively (P<. 001).
The mean length of hospital stay significantly differed between the cases and matched controls (7.69 vs 4.46 days ; P<. 001) as did the mean cost of hospitalization ($10 010 vs $5355 ; P<. 001).
The extra length of hospital stay attributable to an ADE was 1.74 days (P<. 001).
The excess cost of hospitalization attributable to an ADE was $2013 (P<. 001). (...)
