ABSTRACT
Background: "Patient Safety" in everyday practices is a target of healthcare leaders, and adverse events reported by healthcare providers directly reflect patient safety in the health system. Recognising how residents and practising physicians rate adverse events concerning their work conditions and burnout must be explored. Objective: This study aims to explore the mediation effect of burnout dimensions (emotional exhaustion and burnout-interpersonal disengagement) between the effects of work conditions on perceived patient safety by exploring the adverse events that residents and practising physicians reported. Methods: A quantitative and cross-sectional study collected data from 249 residents and practising physicians in a huge teaching hospital and primary health care centre (PHC) in the Eastern Province of Saudi Arabia. Hayes Macro regression analysis was employed to evaluate the multiple mediation effect of burnout dimensions, with 5000 bootstrapping and a confidence interval (CI) of 95% for statistical inference and p≤0.05 for the significance level. Results: Leadership support (B= 0.39, t= 6.24, p<0.001) and physician engagement (B=0.43, t=6.50, p<0.001) were associated with a decreased rate of adverse events to patient safety, whereas workload (B=-0.23, t=-3.73, p<0.001) was negatively associated with an increased rate of adverse events. Burnout was shown to mediate the relationship between the effects of physician's leadership support (R2=0.26, F=27.50, p<0.001), work engagement (R2=0.25, F=27.07, p<0.001) and workload (R2=0.23, F=24.23, p<0.001) on the rate of adverse events. Conclusion: This study provides insights into burnout dimensions and their consequences on patient safety indicators (ie, adverse events). Work conditions (ie, leadership support, physician engagement, and workload) directly affect the rate of adverse events and indirectly through mediators like burnout-emotional exhaustion and burnout-interpersonal disengagement.
ABSTRACT
OBJECTIVES: In this study, we assessed the possible association of adiposity, physical fitness, vitamin D levels and haemodynamic parameters as intermediate risk factors for cardiovascular health in young Saudi women. METHODS: A total of 87 young healthy Saudi women were recruited in this cross-sectional study during 2014-2015. The body weight, height, waist and hip circumference, and plasma 25-hydroxyvitamin D (25[OH] D) levels were measured. The exercise stress test was performed to determine the pulse rate, blood pressure (BP), ECG, and VO2max. Multiple linear regression models were generated for the resting (r) and maximum (m) diastolic (D) and systolic (s) arterial BP and pulse rate (PR), adiposity markers, VO2max, and plasma levels of 25(OH) D. RESULTS: A multiple linear regression model was significant for the rDBP, mDBP, rSBP, and mSBP with adjusted R2 (6.5, 10.2, 8.3, and 4.5%, respectively). Except for VO2max in the mDBP model, none of the included risk factors were significant according to the t-test. CONCLUSION: This study showed the association of high adiposity and decreased physical fitness with haemodynamic parameters in young Saudi women. An exaggerated exercise DBP might predict future cardiovascular risk in unfit young women.
