Predictors of medical care utilization by independently living adults with spinal cord injuries.
A prospective study of 87 independently living adults with spinal cord injury (SCI) as a major disabling condition showed the following average annual health care utilization rates: 1.3 hospital admissions, 16.8 days hospitalized, 1.7 emergency room (ER) visits, and 22.4 outpatient contacts (in person or by telephone). Those hospitalized (n = 66) experienced a mean of 22.2 days hospitalized per person per year. Mean length of stay (LOS) was 11.1 days per admission. Stepwise regression analysis indicated no statistically significant (p less than or equal to .05) predictors of hospital admissions. There were three independent predictors of days hospitalized (greater age, fewer years of education, and more days hospitalized during the previous year), three predictors of days hospitalized for those hospitalized only (greater age, fewer years of education, and longer hospital LOS during the previous year), one predictor of LOS (self-assessment of health), three of emergency room (ER) visits (more unmet instrumental activities of daily living needs, lack of organizational memberships, and more ER visits during the previous year), and five predictors of outpatient contacts (greater age, less satisfaction with health care providers' expressions of concern for their health, lower frequency of leaving apartments, lower levels of life satisfaction, and nonparticipation in a managed medical care demonstration project). Many predictors of health services utilization are immutable. However, changes which facilitate social interaction and changes in the organization of health services may reduce certain types of medical care utilization by people with SCI.
