A “pre-habilitation” program – counseling by a peer coach who has already had a knee replacement – could be helpful to patients scheduled for a knee replacement, to prepare them for the procedure, according to researchers from Hospital for Special Surgery.
This counseling may help empower and inform patients scheduled for the surgery, leading to better outcomes, the study suggests.
Iris Navarro-Millan, MD, MSPH, a rheumatologist at HSS who served as principal investigator, presented the study recently at the American College of Rheumatology/Association of Rheumatology Professionals annual meeting in Atlanta.
“On a national level, up to 30% of patients may have persistent pain after knee replacement surgery for osteoarthritis,” Navarro says, in a media release. “One possible approach to improve outcomes is to optimize muscle strength, physical condition and mental preparation before surgery. Social cognitive theory posits that self-efficacy, peer or social support, sociocultural factors and expectations influence goals and outcomes.”
“There are successful programs in other areas of medicine, such as diabetes care, in which patient navigators share their experience and knowledge with their peers to help them better manage the disease,” states Lisa Mandl, MD, MPH, senior study author and a rheumatologist at HSS. “The thinking is that having the right mindset could optimize outcomes.”
In the study, HSS researchers established focus groups of people who had a knee replacement at HSS to obtain information about their thoughts and experiences. The researchers sought to determine if a “pre-hab” program with trained peer coaches could be helpful and of interest to future patients scheduled for knee replacement surgery.
The investigators defined a peer coach as a patient who has already undergone knee replacement surgery and has been trained to provide personalized pre- and post-knee replacement support.
The 31 patients in the focus groups ranged in age from 65 to 89 and had had a knee replacement at HSS at least 12 months earlier with a good outcome. For almost half the patients, it was their second knee replacement, as they had undergone a previous surgery on their other leg.
“We asked patients about their challenges before and after knee replacement, potential barriers to accessing a pre-habilitation program and perspectives on what it might be like working with a peer coach to encourage exercise prior to knee replacement,” Navarro shares.
The following themes emerged from the focus groups, the release explains:
- Many patients with osteoarthritis delayed knee replacement for many years, often until the pain became very bad.
- Many weren’t sure of the best way to prepare for knee replacement surgery.
- They appreciated advice from other patients about preparation and recovery, and learning about the positive experiences of others often motivated them to have the surgery.
- The concept of peer coaches was well received.
- A few participants were already informally helping others scheduled for surgery and found it very rewarding.
Preparation and expectations for surgery were influenced by patients’ own prior experience with a knee replacement, as well as by the experience of other patients who had already had the surgery, researchers conclude.
“Patients with high outcome expectations who had had a previous knee replacement learned from their first experience and reported feeling motivated to engage in physical activity for muscle strengthening before their second knee replacement,” Navarro comments. “They expressed that their own experiences made them more informed, self-efficacious, and physically active to prepare for their surgery.”
Patients who had had their first knee replacement reported that informally connecting with another individual who had already had the surgery was important in their decision to go ahead with the procedure, and also in preparing for it. They indicated that working with a peer coach would be beneficial for both preparation and recovery.
“Our findings suggest that formal peer-to-peer counseling that prepares patients for their first knee replacement surgery may hold promise to improve outcomes,” Navarro concludes. “Future studies could focus on the best way to establish such a program.”
