- Patient safety as a radiotherapy department: how can we enhance safety?Publication . Eiras, Margarida; Diegues, I.; Grillo, I. Monteiro; Escoval, AnaPurpose: Medical errors can be classified into five categories: poor decision making, poor communication, inadequate patient monitoring, patient misidentification, inability to respond rapidly, and poor patient tracking. Employing innovative information technologies in correcting these deficiencies is the current trend in enhancing patient safety. Radiofrequency (RF) identification is one technology that has significant potential to secure the medical supply chain and increase the safety and efficiency of healthcare processes. It is our purpose to identify patient waiting times; identify treatment unit occupation and guarantee patient and its accessories’ identification.
- Patient safety culture in Portuguese primary care: validation of the Portuguese version of the Medical Office SurveyPublication . Eiras, Margarida; Escoval, Ana; Silva, CarinaBackground: Assessing patient safety culture is a strategic priority worldwide, and Portugal is no exception. Objective: It is the objective of this work to translate, adapt, validate, and analyze the reliability of the Medical Office Survey on Patient Safety Culture in Portuguese Primary Health Care (MOSPSC). Methods: The methodology adopted focused on transcultural translation and adaptation using the Translation Guidelines for the Agency for Healthcare Research and Quality (AHRQ) surveys on Patient Safety Culture, and reliability was conducted using Cronbach’s α and average inter-item correlation. Exploratory factor analysis and confirmatory factor analysis were performed to investigate the observed data that fit the dimensional structure proposed in the AHRQ Portuguese version. Results: The initial sample (n = 7299) was submitted to missing value analysis, obtaining a final sample of 4304 surveys. With exploratory factor analysis, it was obtained a structure with eight composites, one item was removed, and several items moved to other composites. With confirmatory factor analysis, one composite was removed. For both proposed model structures, good results were achieved for the goodness of fit indices. Conclusions: The Portuguese version of the MOSPSC resulted in nine composites with good reliability and construct validity.
- The hospital survey on patient safety culture in Portuguese hospitals: instrument validity and reliabilityPublication . Eiras, Margarida; Escoval, Ana; Grillo, Isabel Monteiro; Silva, CarinaPurpose – Quantitative instruments to assess patient safety culture have been developed recently and a few review articles have been published. Measuring safety culture enables healthcare managers and staff to improve safety behaviours and outcomes for patients and staff. The study aims to determine the AHRQ Hospital Survey on Patient Safety Culture (HSPSC) Portuguese version's validity and reliability. Design/methodology/approach – A missing-value analysis and item analysis was performed to identify problematic items. Reliability analysis, inter-item correlations and inter-scale correlations were done to check internal consistency, composite scores. Inter-correlations were examined to assess construct validity. A confirmatory factor analysis was performed to investigate the observed data's fit to the dimensional structure proposed in the AHRQ HSPSC Portuguese version. To analyse differences between hospitals concerning composites scores, an ANOVA analysis and multiple comparisons were done. Findings – Eight of 12 dimensions had Cronbach's alphas higher than 0.7. The instrument as a whole achieved a high Cronbach's alpha (0.91). Inter-correlations showed that there is no dimension with redundant items, however dimension 10 increased its internal consistency when one item is removed. Originality/value – This study is the first to evaluate an American patient safety culture survey using Portuguese data. The survey has satisfactory reliability and construct validity.
