Sedative-hypnotic use and increased hospital stay and costs in older people.

OBJECTIVE

To assess the relationship between sedative-hypnotic (S/H) utilization, severity of illness, length of stay, and hospital costs among older patients admitted to a tertiary care university hospital.

DESIGN

Retrospective review of computerized hospital and pharmacy data bases.

SUBJECTS

A total of 856 older consecutive medical and surgical admissions from November 1993 to March 1994.

MEASUREMENTS

Sedative/hypnotic utilization in accord with the Health Care Financing Administration (HCFA) guidelines for S/H use in nursing homes. Jefferson Disease Staging to estimate severity of illness. Hospital records to obtain demographic characteristics, length of stay, and hospital costs.

RESULTS

Patients whose S/H use exceeded HCFA guide lines, compared with those within the guidelines and those receiving no drugs, had longer lengths of stay (21.5 days vs 12.3 days vs 6.7 days, P < .001), increased hospital costs ($29,245 vs $15,219 vs $7,516, P < .001). and greater severity of illness (245.8 vs 189.5 vs 148.5, P < .001). S/H use exceeding and within HCFA guidelines were associated with increased length of stay (both P < .0001) and hospital costs (both P < .0001).

CONCLUSIONS

Older hospitalized patients receiving S/H have greater severity of illness, longer lengths of stay, and higher hospital costs compared with other patients. S/H use, and, in particular, S/H use exceeding the HCFA guidelines, are associated with increased hospital stay and cost.
