NONSURGICAL HOSPITALIZATION FOR LOW-BACK-PAIN - IS IT NECESSARY

In 1988, the Diagnosis-Related Group for ''Medical Back Problems'' was the seventh leading reason for all U.S. hospitalizations. The authors sought to describe the content of these hospitalizations and consider the potential for shifting nonsurgical care to the outpatient setting. Three complementary data sources (the 1988 National Hospital Discharge Survey, a statewide Washington hospital discharge registry, and medical records) were used to examine the diagnoses, tests, treatments, resource use, and subsequent care associated with these hospitalizations. Nationally, nonspecific back pain and herniated discs were the most common diagnoses. Nearly half the hospitalizations were for diagnostic tests (especially myelography) and the other half for pain control. In Washington state, 43% of patients were admitted by family physicians or internists, and 40% by orthopedic or neurologic surgeons. Twenty percent of patients underwent subsequent back surgery within 1 year (most within 3 months), suggesting that many hospitalizations were ''presurgical.'' Most of the tests and treatments identified are known to be safe in the outpatient setting. Focused medical record review indicated frequent psychosocial problems or complicating factors, including obesity, substance abuse, prior back surgery, psychologic diagnoses, or lack of a caregiver at home. The findings support other evidence that many hospitalizations for ''medical back problems'' are unnecessary, but also suggest a need for improved outpatient and home-based alternatives to hospitalization.
