Two years ago, the Ontario Ministry of Long-Term Care began testing the implementation of Patient Reported Outcome Measures associated with hip and knee replacement surgeries in hospital setting across the province in 2018. The Mobility Clinic at St. Michael’s served as a pilot site for the project.

Now, staff say they are beginning to see their efforts validated as patients return to the clinic with improved scores following surgery.

Angelo Papachristos, an Advanced Practice Physiotherapist in the Mobility Clinic, explained the Patient Reported Outcome Measures (PROMs) help clinicians understand their patient’s baseline level of disability and track their improvement post-surgery over the course of a year.

“You can track how much pain they were in before surgery, and how much pain they’re in after. That’s data we really didn’t have before,” he said. “That data can help us make improvements in the quality of our care.”

The implementation of the protocol for the collection of the PROMs was challenging at first, according to Nancy Freitas, Clerical Assistant in St. Michael’s Mobility Clinic. The program started on paper, with clericals and physiotherapists inputting and calculating the PROMs themselves.

Six months later the program moved online, successfully overcoming several technical difficulties in the process. It required changing standard clinical practices and the involvement of a multidisciplinary team, including clinical coordinators, senior management, infection control, tech support and clinical staff like orthopedic surgeons and physiotherapists.

“Now, with every single referral that comes in related to hips or knees, we automatically add the patient into the PROMs system. It’s part of our routine,” Freitas said.

Dr. Sarah Ward, an orthopedic surgeon at St. Michael’s, called the clericals and physiotherapists working in the mobility clinic the “unsung heroes” in getting the process off the ground.

When orthopedic surgeons are prescribing pain medication post-operatively, making adjustments to the physiotherapy regimen of patients or implementing new surgical techniques, they will now be able to check to see if those changes are reflected in better PROMs scores, helping to validate that process changes are resulting in improvement.

Surgeons can look at an X-ray, check if an incision has healed or if a knee moves properly, but the PROMs are more telling of how a patient is really feeling, Dr. Ward explained. She said it’s good to see staff’s commitment to making improvements and using evidence-based practice.

“We can see that our patients are in fact doing as well as we think they are,” Dr. Ward said. “That’s why we do what we do, to make patients feel better in their day to day lives.”
