This study was conducted to determine the contributions of sociodemographic factors, medical conditions, and nursing dependency to nursing problems identified and nursing care provided to patients during a home care nursing visit. Patient interviews, direct observation of nursing care, record abstraction, and nurses' reports were used to obtain data from 438 patients receiving nursing visits from a certified home health agency. Nursing dependency was the strongest predictor of the nursing problems of and nursing care provided to home care patients. Measures of nursing dependency should be incorporated in models to determine the extent of nursing problems and nursing care provided in the home and in models of home care nursing reimbursement. © 1993 John Wiley & Sons, Inc.
