A prognostic tool may facilitate the early identification of older adults in the community who would benefit from palliative care in their final years, new research from Canada suggested.
The analysis of data from close to a quarter million community-dwelling older adults in Ontario with at least one interRAI (Resident Assessment Instrument) home care assessment showed that only half of those with an estimated survival of fewer than 3 months received at least one palliative home care visit before death.
“One of the challenges and a barrier to accessing palliative home care is the difficulty of predicting survival,” Amy Hsu, PhD, an investigator at the Bruyère Research Institute in Ottawa, Ontario, Canada, told this news organization. “Clinicians are good at prognosticating when a patient might be entering their last 3-6 weeks of life, but they have a harder time predicting if someone will survive 6 months or longer.”
The team developed the Risk Evaluation for Support: Predictions for Elder-life in their Communities Tool (RESPECT) to see whether access to predicted survival data could inform conversations about a patient’s status and palliative care needs.
The study was published online in the Canadian Medical Association Journal.
Setting Care Goals
Researchers analyzed population health administrative data from Ontario involving home care clients who received at least one interRAI Home Care assessment between April 2018 and September 2019. The cohort included 247,377 adults (62% women) with a mean age of 80.1 years at the time of assessment. Comorbidities, including congestive heart failure, coronary artery disease, cancer, and chronic obstructive pulmonary disease, as well as symptoms of health instability, were more prevalent among those at higher risk of dying.
The team used an updated, validated version of RESPECT to predict survival.
Only 2.6% of home care clients had received a clinician diagnosis of an end-stage disease, which was more prevalent among those at highest mortality risk (77.9%). Most clients (74.5%) required extensive assistance in performing instrumental activities of daily living (ADLs, score ≤ 4), and half (50.3%) were less able to perform ADLs in the last 3 months of life.
Within the cohort, 75% of patients with a predicted median survival of fewer than 3 months, 55.4% of those with a predicted median survival between 3 and 6 months, and 40.7% of those with a predicted median survival between 6 and 12 months died within 6 months of the home care assessment.
Among decedents, 50.6% of those with a RESPECT-estimated median survival of fewer than 3 months received at least one nonphysician palliative home care visit before death. Less than a third (27.8%) received at least one palliative home care visit from a physician.
The proportion of those who received at least one nonphysician visit fell to 38.7% among those with a median survival of between 3 and 6 months and to 29.5% among those with a median survival of between 6 and 12 months.
Patients who received at least one palliative home care visit (from either physicians or nonphysician home care providers) within 6 months of an assessment had clinical characteristics similar to those who did not receive a visit. However, those who did not receive palliative home care were more likely to not have been identified by a clinician as being in their past 6 months of life.
“These results reinforce the role of clinicians in identifying older adults who may be in their last 6 months of life as an important component for the receipt of palliative home care and highlight the value of RESPECT in supplementing clinicians’ assessments of prognosis,” the authors wrote.
“Our goal is to use data and tools like RESPECT to help individuals living with a life-limiting illness have conversations about what their end-of-life care goals and wishes may be and discuss whether a referral to palliative care is appropriate or needed,” Dr. Hsu added. “Data about life expectancy could be helpful for framing these conversations.”
The researchers are working with partners in home, community care, and long-term care to implement RESPECT in their settings.
