Objectives This pilot study assessed clinical outcomes and quality care for persons with dementia in an acute hospital with PCC, compared with usual care.Methods Forty-seven consented persons 60 years and over with dementia were assigned to PCC (n = 26) or usual care (control) (n = 21). Hospital nurses and allied health staff received 3 h of face-to-face education in PCC, and practice support by four PCC-trained nurse champions. Control group staff received 3 h of face-to-face education on dementia and delirium care clinical guidelines. Primary outcomes behavioral/neuropsychiatric symptoms and care quality were analyzed based on repeated measures at baseline (Time 1), 4–5 days after baseline (Time 2) and day 8–10 after baseline (Time 3) where available.Results Compared with controls, at Time 2 PCC produced statistically significant improvements in behavioral/neuropsychiatric symptoms (adjusted p = .036) and care quality (adjusted p = .044). Where length of stay exceeded 8 days after baseline (Time 3), there was a sustained improvement in quality care (p = .007), but not in behavioral/neuropsychiatric symptoms (p = .27).Conclusions PCC can improve care quality for persons with dementia; nursing; agitation; paid caregivers with dementia and reduce behavioral/neuropsychiatric symptoms during short hospital stays.Clinical Implications Hospital systems need to support PCC to reduce behavioral/neuropsychiatric symptoms in dementia during long hospital stays.
