Hip And Knee Replacement: Home Discharge Insights
By: Lisa Remington, President, Remington Health Strategy Group, Publisher The Remington Report
Large studies support that patients sent home after knee and hip replacements do not have higher rates of medical complications, returns to the hospital or emergency room visits than those who went to rehabilitation facilities.
A March study in the Journal of the American Medical Association (JAMA) of 17 million Medicare hospitalizations from 2010 to 2016 for knee and hip replacements reports that people who were sent home with home health care services demonstrated the same level of functional improvement as those who went to a SNF.
“What this study tells us is it’s certainly safe to send people home under many circumstances,” said Dr. Vincent Mor, a professor of health services, policy and practice at Brown University’s School of Public Health who wrote an editorial accompanying the study.
Assessments examined their ability to walk and get up and down stairs, among other activities. And they were no more likely to die 30 days after surgery (a very small percentage in each group). Overall, costs were significantly lower for patients who went home, while hospital readmissions were slightly higher—a possible signal that home health care services needed strengthening or that family caregivers needed better education and training.
Other Studies Came to the Same Conclusion
The report expanded on previous research that came to a similar conclusion. In 2017, experts from New York City’s Hospital for Special Surgery published a study that examined 2,400 patients who underwent total knee replacements and were discharged at home or to a SNF for rehabilitation between May 2007 and February 2011. There were no differences in complication rates at six months or in functional recovery and patient-reported outcomes at two years.
“As a result of these findings, we are encouraging all of our patients to consider home discharge after TKA (total knee arthroplasty),” the authors wrote.
The year before, researchers at New York University reported in JAMA Internal Medicine that from 2009 to 2012 and 2013 to 2014, discharges to rehabilitation facilities fell from 68% to 34% for patients undergoing hip and knee replacements, from 71% to 22% for patients with cardiac valve replacement surgeries, and from 40% to 30% for patients who’d had spinal fusion surgery. Instead, more people were sent home to recover. During this period, NYU Langone Medical Center assumed financial responsibility for “episodes of care” for joint replacements that include the post-hospital recovery period—a policy that Medicare is now promoting.
Diane Rubin, 67, who lives on Long Island, had a hip replacement at the NYU medical center in January. Before the surgery, she got a list of things she’d need to do to prepare for her recovery; afterward, a nurse and physical therapist visited her at home regularly for about three weeks. “I was more comfortable recuperating at home and I’ve had absolutely no complications,” she said.
How Do Physicians Decide About Where Patients Should Go?
How do physicians decide where to send patients? “In general, we tend to send patients to skilled-nursing facilities who are older, sicker, more deconditioned after surgery, and who have no spouse or caregiver, fewer resources and little social support,” said Dr. Leora Horwitz, a co-author of that study and associate professor of population health and medicine at NYU School of Medicine.
Though it’s widely believed that people who live alone might not do well going home, last year researchers at the Rothman Orthopaedic Institute at Thomas Jefferson University in Philadelphia published research showing that isn’t necessarily the case. At their institution, patients are assigned a nurse navigator who provides assistance before and after hip or knee replacements. Patients who lived alone stayed in the hospital longer and received more home health services than those who lived with others.
When they recuperated at home, the Rothman Orthopaedics patients didn’t have higher rates of medical complications, returns to the hospital or emergency room visits than those who went to rehabilitation facilities. Nearly 90% of people who lived alone said they’d again choose a home discharge.
Dr. William Hozack, a co-author of the study and professor of orthopedic surgery at Thomas Jefferson University Medical School, acknowledged that patients who go to rehab are probably sicker and more debilitated than those who go home, potentially biasing research results. Still, practices have changed considerably. Today, he and his colleagues send 95% of patients who get hip and knee replacements home to recover.
People shouldn’t underestimate how much help they may require at home, especially in the first few weeks after surgery, said Carol Levine, director of the United Hospital Fund’s families and healthcare project, who has had two hip replacements. The potential downsides to going home include a greater burden on caregivers and the possibility that complications won’t be identified as quickly, needs will go unmet if friends and family can’t pitch in, and people won’t follow through on recommended rehabilitation regimens. And outcomes may not be as favorable if services that support people at home aren’t readily available.
Intermountain’s at Home Program
Salt Lake City-based Intermountain Healthcare is bringing an array of services—palliative care, dialysis, primary care and hospital care—into the home through its new Intermountain at Home program. Recovering at home after a hospital procedure is also a focus, and Intermountain has created standardized procedures for hip and knee replacements over the past few years, according to Rajesh Shrestha, the system’s chief operating officer of community-based care.
Every joint-replacement patient going home after surgery now gets a thorough assessment to determine the resources needed. A care plan is created and a case manager, usually a registered nurse, makes sure that physical therapy, durable medical equipment and home health care are supplied. The case manager also coordinates postoperative care with orthopedic surgeons and makes sure that patients reconnect post-surgery with their primary care physicians. And a team of providers is available 24/7.
"During the past few years, discharges to rehab facilities have declined by half at most of Intermountain’s Utah facilities, with no notable increase in complications or hospital readmissions, Shrestha said. During 2018, 85% of knee replacement patients and 88% of hip replacement patients went home after surgery, respectively."
Kaiser Permanente – 50% Same-Day Joint Replacement Discharged to Home
At Kaiser Permanente, which has a health plan with more than 12 million members, a substantial number of patients who get elective hip and knee replacements are skipping a hospital stay altogether and going home the same day. In Kaiser’s Southern California region, same-day joint replacement home discharges now total about 50%, according to Dr. Nithin Reddy, who oversees joint replacements for the region. (Kaiser Health News is not affiliated with Kaiser Permanente.)
Kaiser Permanente has made this possible by introducing new protocols for pain management (opioids are used less frequently), altering anesthesia protocols (less general anesthesia and more regional anesthesia), reducing blood transfusions and hiring “total joint coordinators,” typically nurses, to help with the transition from the hospital to home, among other changes. All patients go home with home health care, receive two outreach calls the week after surgery and get comprehensive handbooks with checklists of what to do before and after surgery and common concerns to look out for.
“We have very robust discharge criteria: Patients have to have well-managed pain and be able to get in and out of bed by themselves and in and out of the restroom by themselves. And they need to be able to walk 50 to 75 feet unassisted, using a walker,” Reddy said. “If they can’t do those things, they aren’t safe for a home discharge and (rehabilitation at) a skilled-nursing facility would come into play.”
Magdalena Ritayik, 66, one of the doctor’s patients, had a knee replacement last September after cortisone shots stopped working and pain became a constant companion. Six years before, her husband had both knees replaced, separately, and stayed in the hospital three days each time. By contrast, Ritayik went home the afternoon after her surgery, only to find a nurse and physical therapist waiting there for her.
“The nurse went over all the medications, when to take them and how much. The physical therapist showed me how to do bending and stretching with a chair in the living room and to raise my leg while I was lying on the bed,” Ritayik said. “The first week you have to stay home. After the second week, I was walking almost like regular. A month after the surgery, I was at full extension and full bending.”
