Abstract

Introduction: Safety culture is considered one of the most crucial premises for further development of patient care in healthcare. During the eight-year economic crisis (2010–2018), Greece made significant reforms in the way the primary health care system operates, aiming at the more efficient operation of the system without degrading issues of safety and quality of the provided health services. In this context, the aim of this study was to set a reference evaluation for the patient safety culture in the primary health sector in Greece, based on health professionals’ perceptions. Materials and Methods: A specialized tool - the Medical Office Survey on Patient Safety Culture (MOSPSC) - developed by the Agency for Healthcare Research and Quality (AHRQ), validated in order to evaluate Greek primary care settings in terms of safety culture and quality. Factor analysis determined the correlation of the factor structure in Greek data with the original questionnaire. The relation of the factor analysis with the Cronbach’s coefficient alpha was also determined, including the construct validity. Results: Eight composites with 34 items were extracted by exploratory factor analysis, with acceptable Cronbach’s alpha coefficients and good construct validity. Consequently, the composites jointly explained 62% of the variance in the responses. Five items were removed from the original version of the questionnaire. As a result, three out of the eight composites were a mixture of items from different compounds of the original tool. The composition of the eight factors was similar to that in the original questionnaire. A stratified random sampling with a 62% response rate (n = 459), conducted in primary care settings in Greece (February to May 2020). The study participants were health professionals who interacted with patients from 12 primary care settings in Greece. The most highly ranked domains were: “Teamwork” (82%), “Patient Care Tracking/Follow-up” (80% of positive scores), and

Abstract

This study establishes typical Diagnostic Reference Levels (DRL) values and assesses patient doses in computed tomography (CT)-guided biopsy procedures. The Effective Dose (ED), Entrance Skin Dose (ESD), and Size-Specific Dose Estimate (SSDE) were calculated using the relevant literature-derived conversion factors. A retrospective analysis of 226 CT-guided biopsies across five categories (Iliac bone, liver, lung, mediastinum, and para-aortic lymph nodes) was conducted. Typical DRL values were computed as median distributions, following guidelines from the International Commission on Radiological Protection (ICRP) Publication 135. DRLs for helical mode CT acquisitions were set at 9.7 mGy for Iliac bone, 8.9 mGy for liver, 8.8 mGy for lung, 7.9 mGy for mediastinal mass, and 9 mGy for para-aortic lymph nodes biopsies. In contrast, DRLs for biopsy acquisitions were 7.3 mGy, 7.7 mGy, 5.6 mGy, 5.6 mGy, and 7.4 mGy, respectively. Median SSDE values varied from 7.6 mGy to 10 mGy for biopsy acquisitions and from 11.3 mGy to 12.6 mGy for helical scans. Median ED values ranged from 1.6 mSv to 5.7 mSv for biopsy scans and from 3.9 mSv to 9.3 mSv for helical scans. The study highlights the significance of using DRLs for optimizing CT-guided biopsy procedures, revealing notable variations in radiation exposure between helical scans covering entire anatomical regions and localized biopsy acquisitions.

The composition of the five factors was similar to that in the original questionnaire. CONCLUSIONS: The MOSPSC tool in Greek primary healthcare settings can be used to assess patient safety culture in facilities across the country. From the study, the patient safety culture in Greece was positive, although few composites showed a negative correlation and needed improvement.

Abstract

The hospital environment is often quite complicated due to interdisciplinary workflow procedures and multitasking staff, which are exacerbated during periods of economic crisis. This study aimed to examine the motivation and job satisfaction factors of Greek National Healthcare Service (NHS) employees in relation to the Existence-Relatedness-Growth (ERG) theory of motivation during a period of severe financial constraints. A cross-sectional study was conducted in three public hospitals in Greece from 2018 to 2019, utilizing a survey tool to measure the factors of motivation and job satisfaction among Greek NHS employees. The study also aimed to identify the most relevant motivational theory applicable to the complex Greek hospital environment. Exploratory factor analysis (EFA) was employed to extract the structural factors of the survey tool, and analysis of variance (ANOVA) was used to identify statistical differences between the means of three or more independent groups. A sample of 363 Greek NHS employees participated in this study. Statistically significant differences were detected between hospital units and job satisfaction factors, as well as between the functions of hospital clusters and job positions. Specifically, managerial staff presented higher levels of job satisfaction, while nursing staff had the lowest scores in terms of psychological contracts when compared to medical and administrative staff. This study demonstrated that job satisfaction in Greek public hospitals, in a context of severe financial constraints, was mainly driven by strong interpersonal connections and employee trust in management, despite significant cuts in salaries, staff numbers, and hospital budgets., Competing Interests: Human subjects: Consent was obtained or waived by all participants in this study. North Attica Hospital Cluster Ethics Committee (Sismanoglio-Amalia Fleming and Paidon Pentelis) issued approval 12813/14-6-18.
