With pay for performance on the horizon, a new study highlights problems with OASIS validity and reliability. The study findings suggest OASIS may not truly reflect the patient's condition. This supports industry experience, experts say.
The study, conducted by the Visiting Nurse Service of New York's Center for Home Care Policy and Research, found reliability for many items "considerably lower than prior studies" including those conducted by the University of Colorado's Center for Health Policy Research.
VNS-NY, which describes the study in the Home Health Care Services Quarterly, points out significant problems with inter-rater reliability and concludes that previous studies "had not accounted for the stresses and unpredictability of the home health care setting."
Best advice: Training is very important because repeated use of OASIS alone does not improve accuracy, VNS-NY researcher Robert Rosati tells Eli. "Training should reinforce the importance of observing functional abilities and emphasis should be placed on clarifying the subtle differences between answer choices in the OASIS items," he advises.
