Improving the standardisation, timeliness and efficiency of the occupational therapy admission process in an older adult inpatient service.

Occupational therapists (OTs) are at the forefront of providing recovery-oriented care for older people through timely assessments of patient's engagement in daily living activities among many other interventions. This aids a timely, safe and successful discharge from hospital.This project built on the foundations of previous work while considering the context and requirements of two older adult wards, the rates of admission and staff retention. The specific aim agreed was for 90% of patients admitted to the older adults' inpatient units to be assessed by the occupational therapy (OTY) team within days of admission by December 2022.The OTs worked in collaboration to initiate two tests of change with a total of five PDSA cycles.Our tests of change resulted in an increase of patients engaging in OTY initial assessments within seven days of admission from 47.65% (May to November 2021) to 78% (December 2021 to December 2022).Our team embarked on a quality improvement project to improve standardisation, efficiency and timeliness of the OTY process in an older adult inpatient service by using a pragmatic measure and tests of change evidenced in a previous study. This evidenced the generalisability of the findings of this study. While we were able to improve the timeliness of OTY initial assessments, we concluded that the overall impact on outcomes such as timely discharge was also dependent on other clinical and social factors.

Wnt signaling in estrogen-induced lactotroph proliferation.

Prolactinomas are the most common type of functioning pituitary adenoma in humans, but the control of lactotroph proliferation remains unclear. Here, using microarray analysis, we show that estrogen treatment increased expression of Wnt4 mRNA in adult Fischer rat pituitary tissue. Dual immunofluorescence analysis revealed that Wnt4 expression was not confined to lactotrophs, but that it was expressed in all anterior pituitary cell types. Estradiol induced proliferation in the somatolactotroph GH3 cell line, in parallel with Wnt4 mRNA and protein induction. A reporter gene assay for TCF- and LEF-dependent transcription revealed that there was no activation of the canonical Wnt pathway in GH3 cells upon stimulation with Wnt-conditioned culture medium or coexpression of constitutively active mutant ß-catenin. Expression of ß-catenin in both GH3 cells and normal rat anterior pituitary cells was restricted to the cell membrane and was unaltered by treatment with estradiol, with no nuclear ß-catenin being detected under any of the conditions tested. We show for the first time that Wnt4 affects non-canonical signaling in the pituitary by inhibiting Ca(2+) oscillations in GH3 cells, although the downstream effects are as yet unknown. In summary, Wnt4 is expressed in the adult pituitary gland, and its expression is increased by estrogen exposure, suggesting that its involvement in adult tissue plasticity is likely to involve ß-catenin-independent signaling pathways.
