We examined the quality of care provided to older persons with frailty in five Canadian provinces, using administrative health data. In each province, we identified two cohorts of older persons with frailty: decedents and living persons. Using decision rules, we considered individuals to be frail if they were long-term care residents, terminally ill, or met at least two of seven domains, which were based on frailty scales, geriatrician discussions, and health service utilization indicators. We assessed quality of care using selected quality indicators: decrease in length of hospital stay, decrease in the number of in-patient readmissions, decrease in the number of emergency department visits, increase in the level of family physician continuity of care, decrease in the use of mechanical ventilation, and decrease in the number of admissions to intensive care. Using regression analyses, we also found male sex and older age were associated with poorer quality of care in both cohorts. This study provides baseline data for evaluating future efforts to improve the quality of care provided to older persons with frailty.
