Abstract

CONTEXT:

Successful outcome of complex surgical techniques depend on the surgical team's level of experience. However, unless benefit is demonstrated in the presence of cost savings, insurance companies are reluctant to approve care from highly experienced hospitals and surgical teams.

OBJECTIVE:

To determine the relationship between the number of acoustic neuroma surgeries performed at California hospitals with surgical outcome and hospital stay cost.

DESIGN:

Acoustic neuroma surgery information was extracted from the California hospital discharge database and was grouped according to the number of surgeries performed at each hospital.

SETTING:

A database review of California hospitals.

PATIENTS:

Persons (n=1,213) undergoing acoustic neuroma surgery at a California hospital between 1996 and 1998. Main outcome measures Outcome measures included discharge status (routine vs. not routine), medical procedures indicating surgical complications, total cost of hospitalization, and average cost per hospitalization day. Odds ratios were used to compare the hospital volume groups on likelihood of a routine surgical outcome.

RESULTS:

The frequency of routine surgical outcome increased as hospital acoustic neuroma surgical volume increased, ranging from 68% among patients in the lowest volume group to 97% in the highest hospital volume group. Patients in the highest hospital volume group were 15 times more likely to have a routine surgical outcome than patients in the lowest hospital volume group. Patients in the second highest volume group were 5 times more likely to have a routine surgical outcome than in the lowest volume group. The two highest volume hospital groups had lower total charges and average charges per day than the two lower volume hospital groups.

CONCLUSIONS:

Acoustic neuroma surgeries at higher volume hospitals had higher frequency of routine discharge, lower frequency of apparent complications, and lower average cost of hospitalization.
