Evaluation of a formal care worker educational intervention on pressure ulceration in the community.

AIMS AND OBJECTIVES: To develop and evaluate an educational intervention for formal care workers on pressure ulceration in the community. BACKGROUND: Pressure ulcers are a major burden to health care and with an ageing population likely to increase. Formal care workers are ideally placed to identify high risk but lack standardised educational provision. DESIGN: An insider approach to action research in one provider organisation, November 2014-May 2015. METHODS: Number and categorisation of pressure ulcers, within three community nursing teams before and four months after intervention was delivered to a purposive sample (n = 250) of formal care workers, were assessed and the taught element evaluated using a questionnaire and verbal feedback. RESULTS: Total number of pressure ulcers reduced from 28-20, category II, 19-11, III unchanged at 6 and IV from 2-0 following the educational intervention. Key risk factors included impaired mobility (71%), urinary incontinence (61%) and previous pressure damage (25%), and 71% had formal care worker input. The intervention was highly rated 4·95/5 by 215 (86%) formal care workers in the evaluation questionnaire. CONCLUSIONS: Formal care workers receive little, if any, education on pressure ulceration. An educational intervention can have a positive effect within community care, with the potential to reduce direct costs of care. However, a standardised approach to education is required; an urgent review of the education provision to formal care workers, in the UK and around the world, is therefore essential if the potential that formal care workers offer is to be realised. RELEVANCE TO CLINICAL PRACTICE: Formal care workers are ideally placed to help identify and alert healthcare professionals about patients at high risk of developing pressure ulcers. If this potential is to be realised, a standardised approach to education is required.

Practice effects in three-dimensional sequential rapid aiming in Parkinson's disease.

One hypothesized role of the basal ganglia, based largely on findings in Parkinson's disease (PD) patients, is the control of movement sequences. We examined changes in performance with practice of a movement sequence in PD patients and age-matched controls (n = 8 per group). Subjects practiced a complex three-dimensional sequential aiming task over 2 days, completing 180 trials, with the goal to minimize response time within specified accuracy limits. The results indicated that both groups became faster in planning the movement, and both groups moved more quickly through the sequence with practice. The PD group's decrease in movement time occurred primarily within the first 45 trials, whereas the control group continued to improve through the first 150 trials. Flight time (time between targets) to a small target decreased with practice in both groups, but flight time to a large target decreased only in the control group. This finding indicates that error corrective processes are more amenable to practice than ballistic processes in people with PD. There was little evidence that either group improved their performance by planning shorter (lower) trajectories, but rather increased mean velocity. Contact time (time on target) decreased with practice in both groups, and there were no group differences. These data indicate that practice can improve performance, both in planning and in specific execution processes.
