The hospital survey on patient safety culture in Portuguese hospitals: instrument validity and reliability

Purpose – 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.

As guardas de segurança para proteção a motociclistas: características e graus de eficácia

Os acidentes envolvendo veículos de duas rodas, são um dos maiores problemas da segurança rodoviária atual, no âmbito Europeu. Um dos tipos de acidentes que pode causar danos mais graves aos ocupantes desses veículos é o embate com guardas de segurança. Em consequência disso, neste trabalho foram desenvolvidas opiniões, abonatórias ou não, ao uso de dispositivos de proteção para motociclistas acoplados nas guardas de segurança. Estas opiniões vão partir de dados estatísticos, de estudos e exemplos concretos de vários autores e publicações relacionados com esta temática, sendo que o tipo de dispositivo de proteção para motociclistas que vai estar mais em foco e sendo ele o mais habitual nas estradas portuguesas será a saia metálica. Estes dispositivos de segurança para motociclistas ainda não são de uso obrigatório nas guardas de segurança na maioria dos países do continente Europeu, segundo a norma europeia EN 1317, apesar deste tipo de proteção já estar normalizada segundo padrões de lesões biomecânicos na zona da cabeça, cervical e anca/abdómen descritos na norma EN 1317 UNE 135900 – 1:2003, em alguns países é descurado o uso destas proteções, por não serem obrigatórias e porque ainda se tornam mais dispendiosas que as guardas de segurança habituais (barreiras de metal simples). Este estudo serviu essencialmente para verificar se estes dispositivos salvaguardam ou não a vida dos utilizadores de duas rodas, pois, se pelo contrário, aumentam ainda o risco, ou de lesões mais gravosas ou mesmo de morte, aquando o embate com as mesmas, os gastos associados a este tipo de equipamentos serão totalmente inúteis e desnecessários.

A checklist for patient safety rounds at the care pathway level

Objective - To define a checklist that can be used to assess the performance of a department and evaluate the implementation of quality management (QM) activities across departments or pathways in acute care hospitals. Design - We developed and tested a checklist for the assessment of QM activities at department level in a cross-sectional study using on-site visits by trained external auditors. Setting and Participants - A sample of 292 hospital departments of 74 acute care hospitals across seven European countries. In every hospital, four departments for the conditions: acute myocardial infarction (AMI), stroke, hip fracture and deliveries participated. Main outcome measures - Four measures of QM activities were evaluated at care pathway level focusing on specialized expertise and responsibility (SER), evidence-based organization of pathways (EBOP), patient safety strategies and clinical review (CR). Results - Participating departments attained mean values on the various scales between 1.2 and 3.7. The theoretical range was 0-4. Three of the four QM measures are identical for the four conditions, whereas one scale (EBOP) has condition-specific items. Correlations showed that every factor was related, but also distinct, and added to the overall picture of QM at pathway level. Conclusion - The newly developed checklist can be used across various types of departments and pathways in acute care hospitals like AMI, deliveries, stroke and hip fracture. The anticipated users of the checklist are internal (e.g. peers within the hospital and hospital executive board) and external auditors (e.g. healthcare inspectorate, professional or patient organizations).

Fire safety barrier availability analysis

This paper shows several ways to analyse the performance of a safety barrier, depending on the objective to be achieved and present a method to analyse binary components usually present on sensor systems of safety barriers. An application example of a water-based fire system is presented and the Probability of Failure on Demand (PFD) of the sensor system is determined based on the analysis of pressure switches installed in this safety barrier. The knowledge of such information will allow the determination of safety barrier’s availability.
