Hospital records from 40 back pain patients in private rooms and 40 back pain patients in semi-private rooms were reviewed to determine: (a) if patients in private rooms used more narcotics than patients in semi-private rooms; and (b) whether room type was a predictive variable for narcotic utilization. Patients in private rooms were found to be more likely to use intramuscular request-contingent narcotics than similar patients in semi-private rooms. No differences in the amount of narcotics were observed for other categories of narcotic analgesics. Room type, relevant medical, and demographic variables failed to account for this difference in medication utilization, suggesting that other factors such as medical staff and patient personality variables may be playing an important role in contributing to the use of narcotic analgesics by back-pain patients.
