 PATIENT REPORTED OUTCOME MEASURES
Patient reported outcome measures (PROMs) are important tools used to measure a patient’s perception of their health status. A survey to assess the patient’s opinion of their joint-specific pain and functional abilities is sent to all HOI joint replacement patients pre and post-surgery. Patients electing to have joint replacement surgery at HOI had significant improvements on joint-specific PROMs.

Veterans RAND 12-Item Health Survey (VR-12)
Pre-op 1 Year
Preoperative mean score out of 100: 45.4; standard deviation: 19.4. Patient-reported improvement at one year – mean score: 78.1; standard deviation: 16.1.
The VR-12 is a global patient-reported health measure to assess the patient’s overall perspective of his or her health. It includes physical functioning, role limitations due to physical or mental health problems, pain, energy, mental health, social functioning and general health. Both knee and hip replacement patients reported significant improvement at one year post-surgery.
