Proficiency-based training and evidence-based methodology: a systematic review and meta-analysis.

OBJECTIVE: To assess adherence of self-labelled proficiency-based progression (PBP) studies to evidence-based PBP criteria and examine associations with training outcomes. METHODS: A systematic review and meta-analysis were conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines and registered in the International Prospective Register of Systematic Reviews. PubMed, CENTRAL, EMBASE, MEDLINE, and Scopus were searched from inception to 1 March 2023. Prospective English-language studies on healthcare procedural training reporting objective performance outcomes were included; non-prospective, non-quantitative, non-procedural, non-English studies, and reviews were excluded. Pre-specified outcomes included adherence to 18 evidence-based PBP criteria and objective performance metrics (errors, steps, time); secondary outcomes included proficiency benchmark achievement and Likert ratings. Data extraction was performed independently by multiple reviewers. Study quality was assessed using the Medical Education Research Study Quality Instrument and risk of bias by two investigators. Effect sizes were pooled using random-effects models (DerSimonian-Laird), expressed as the ratio of means (ROM) for continuous outcomes and bias-corrected odds ratios for dichotomous outcomes. RESULTS: Of 646 studies identified 175 met inclusion criteria. In the PBP studies (n = 18), 94% fulfilled minimum criteria (use of a proficiency benchmark, its quantitative definition, and requirement for demonstration prior to progression) vs 36% of non-PBP studies (n = 157). If all PBP criteria were included, 83% of PBP studies used these criteria vs only 2% of non-PBP-studies. In quantitative analysis (27 randomised clinical studies, 761 participants), ROM results showed that PBP training reduced the number of performance errors by 58% (P < 0.001) and procedural time by 28% (P = 0.006), increasing number of steps performed by 22% (P = 0.03). When stratified based on number of criteria fulfilled, meta-regression demonstrated that increasing the number of PBP criteria fulfilled was associated with progressive and systematic trainee performance improvement. CONCLUSIONS: The more training methodologies adhere to established PBP criteria, the better training outcome will be.

Electrophysiological and information processing variability predicts memory decrements associated with normal age-related cognitive decline and Alzheimer's disease (AD).

Recent theoretical models of cognitive aging have implicated increased intra-individual variability as a critical marker of decline. The current study examined electrophysiological and information processing variability and memory performance in normal younger and older controls, and older adults with Alzheimer's disease (AD). It was hypothesized that higher levels of variability would be indicative of age-related and disease-related memory deficits. Results indicated both implicit and explicit memory deficits associated with AD. Consistent with previous research, behavioral speed and variability emerged as sensitive to age- and disease-related change. Amplitude variability of P3 event-related potentials was a unique component of electrophysiological activity and accounted for significant variance in reaction time (RT) mean and RT standard deviation, which in turn accounted for significant variance in memory function. Results are discussed in light of theoretical and applied issues in the field of cognitive aging.

The concept of health scale: developed for Chinese people with chronic illness.

BACKGROUND: As the concept of health in Chinese people with chronic illness had not been previously explored, a scale to measure this concept in this client group was developed. OBJECTIVE: To develop and test the psychometric integrity of the Concept of Health Scale (CHS) for use with Chinese people. METHODS: Previous nursing experience and a literature review were used to inform the initial development of the CHS. It was revised following scrutiny by a panel of experts. Two studies tested the psychometric integrity of the scale. In Study One the data gathered from 80 Chinese people with a chronic illness were subjected to item analysis and exploratory factor analysis. In Study Two, with a convenience sample of 372 chronically ill Chinese people, confirmatory factor analysis was conducted. RESULTS: Instrument analysis in Study One resulted in a 34-item scale with a Cronbach alpha of 0.94. The results of an exploratory factor analysis showed that physical, psychosocial, and spiritual factors were represented by the CHS. The hypothesized model of the CHS was tested in Study Two using confirmatory factor analyses. The results of this study indicated that the concept of health was comprised of six first-order and three second-order factors. CONCLUSION: The results of this study demonstrated that Chinese people with chronic illness held a broad frame of reference in gauging the concept of health. The development of the CHS brings us one step closer to understanding how Chinese people with chronic illness regard the concept of health.
