Quality-of-Care Processes in Geriatric Assessment Units: Principles, Practice, and Outcomes

Abstract

To assess quality-of-care processes and to examine whether care processes are associated with short-term postdischarge outcomes in older vulnerable hospitalized patients. Retrospective study. Forty-nine Geriatric Assessment Units. Patients aged 65 and older who were admitted to a Geriatric Assessment Unit for a fall with trauma. Three care processes (comprehensiveness, informational continuity, patient-centered care) assessed through chart audit; three-month postdischarge outcomes (emergency department visit, hospital readmission, and death) obtained from national databases. A total of 934 hospitalization records were included. Mean comprehensiveness and informational continuity scores were 55% ± 12% and 42% ± 16%, respectively. Items related to geriatric global assessment (eg, functional autonomy) were particularly overlooked. Patient-centered care was poorly provided, with only 24% of hospitalization records showing evidence of advance care directives and at least one patient/family meeting with the physician to discuss clinical evolution. For the three care processes, a large variability among Geriatric Assessment Units was observed. Better comprehensiveness of care was associated with lowered short-term mortality (OR = 0.73, 95% CI = 0.55-0.96, P = .023), whereas higher scores on informational continuity was associated with fewer emergency department visits (OR = 0.91, 95% CI = 0.82-1.00, P = .046), hospital readmissions (OR = 0.84, 95% CI = 0.74-0.94, P = .003), and mortality (OR = 0.72, 95% CI = 0.59-0.88, P = .002). Patient-centered care was not associated with any of the postdischarge outcomes. A large gap between geriatric care principles and practice in Geriatric Assessment Units has been observed. Our results show that improvement in care processes may be translated to decreased short-term health services use and mortality.
