Improving Healthcare Quality and Clinical Outcomes for Persons with Dementia in the Sub-Acute Hospital Through Person-Centered Care Practice.

Background: Person-centered care is considered beneficial for persons with dementia. Objective: To evaluate the impact of a person-centered knowledge translation intervention on the quality of healthcare and outcomes for persons with dementia. Methods: Over nine months, sub-acute hospital nursing, allied health, and medical staff (n = 90) participated in online and/or face-to-face person-centered education and were supported by senior nursing, allied health, and medical staff champions (n = 8) to implement person-centered healthcare. The quality of healthcare service, ward climate and care delivery were evaluated pre/post study intervention. In the week following hospital admission (Time 1) and week of discharge (Time 3), agitation incidence (co-primary outcome) was assessed in participants with dementia (n = 80). Participant delirium (co-primary outcome), accidents/injuries, psychotropic medicines, length of stay, readmission and discharge destination (secondary outcomes) were compared with a retrospective group (n = 77) matched on demographics, cognition and function in activities of daily living. Results: Improvements occurred post-intervention in service quality by 17.5% (p = 0.369, phi = 0.08), ward climate by 18.1% (p = 0.291, phi = 0.08), and care quality by 50% (p = 0.000, phi = 0.37). Participant agitation did not change from Time 1 to Time 3 (p = 0.223). Relative to the retrospective group, significant reductions occurred in participant delirium (p = 0.000, phi = 0.73), incidents/injuries (p = 0.000, phi = 0.99), psychotropic medicine use (p = 0.030, phi = 0.09), and hospital readmissions within 30 days (p = 0.002, phi = 0.25), but not in discharge to home (p = 0.171). Conclusions: When person-centered healthcare knowledge is translated through staff education and practice support, persons with dementia can experience improved healthcare services and clinical outcomes, while healthcare services can benefit through reductions in unplanned service use.

Changes in Mood, Anxiety, and Cognition with Polycystic Ovary Syndrome Treatment: A Longitudinal, Naturalistic Study.

Purpose: Individuals with polycystic ovary syndrome (PCOS) are at increased risk of depression and anxiety symptoms and impairment in aspects of cognitive function. However, there is little evidence regarding effects of standard treatment for PCOS on these features of the syndrome. The aim of this study was to examine the effect of 12 weeks of naturalistic treatment of PCOS, with usual medications, on depression symptoms, anxiety symptoms and cognitive function. Patients and Methods: Thirty-three participants with PCOS received 12 weeks of individualised treatment based on clinical presentation. Changes in depression and anxiety symptoms were assessed with the self-report Hospital Anxiety and Depression Scale at baseline and 12 weeks, and cognitive function was assessed at the same time-points with a battery of tests spanning cognitive domains of verbal learning and memory, visuospatial learning and memory, psychomotor speed, attention and executive function. Outcomes were compared with a control group of 40 healthy participants. Results: Participants with PCOS (mean age = 29.2 years; mean Body Mass Index = 27.4) were treated with a variety of medications, predominantly spironolactone (n = 22) and oral contraceptives (n = 16). Depression and anxiety symptoms improved significantly over the course of treatment, with moderate effect sizes (Cohen's d 0.43-0.55, p < 0.05). Effect sizes of the difference in change from that of the control group were moderate but did not reach statistical significance. Women undergoing PCOS treatment demonstrated significant improvements in aspects of cognitive function, but improvement did not differ significantly from controls and effect size changes were similar, suggesting practise effects in both groups. Conclusion: Our study provides preliminary evidence that treatment of PCOS may be associated with improvement in psychiatric aspects of the syndrome, particularly depressive symptoms.

Free testosterone is related to aspects of cognitive function in women with and without polycystic ovary syndrome.

Evidence suggests impairment in aspects of cognitive function in women with polycystic ovary syndrome (PCOS). Direct effects of raised testosterone levels associated with PCOS are a potential mechanism. We aimed to explore the relationship between testosterone levels and cognitive functioning in women. Women with a range of testosterone levels, including women with PCOS, were recruited. Depressive and anxiety symptoms were measured by self-report. Participants underwent a comprehensive battery of cognitive tests assessing psychomotor speed, visuospatial learning and memory, verbal learning and memory, and executive function. Free testosterone serum levels were assessed. All measures were completed at the same time point. Correlation analysis (Spearman's Rho) was used to explore associations between free testosterone and cognitive test variables. Eighty-one women were recruited, with 40 meeting diagnostic criteria for PCOS. Free testosterone was normally distributed, with significant overlap between women with PCOS and controls. Mean depressive and anxiety symptoms were in the mild range. Higher free testosterone levels were significantly correlated with poorer performance on measures assessing psychomotor speed and visuospatial learning. These significant correlations remained after adjusting for confounders (premorbid verbal IQ, depressive, and anxiety symptoms). Higher free testosterone levels in women were associated with poorer cognitive function, specifically psychomotor speed and visuospatial learning. Women with PCOS and raised free testosterone levels may experience impairment in these aspects of cognitive function which are not accounted for by mood or anxiety symptoms.
