ABSTRACT

BACKGROUND: Recently, fatigue has received more attention as a workplace hazard. This scoping review focuses on fatigue in anaesthesia providers. We explore the prevalence of fatigue in anaesthesia providers, and we examine how fatigue impacts their performance. METHODS: A literature search was independently conducted from December 2019 through March 2020. The following four databases were consulted: MEDLINE, CINAHL, EMBASE, and PubPsych. Only studies discussing fatigue in anaesthesia providers were eligible. RESULTS: The initial database search identified a total of 118 studies, of which 30 studies were included in the review. Eight articles concerned the prevalence of fatigue in anaesthesia providers, whereas 22 explored the impact of fatigue on the performance of anaesthesia providers. Up to 60.8% of anaesthesia providers suffered from severe excessive daytime sleepiness, and fatigue was denoted as a common workplace problem in up to 73.1% of anaesthesia providers. Fatigue had a negative influence on medication errors and vigilance, and it decreased the performance of anaesthesia providers during laboratory psychomotor testing. There was a decrease in non-technical skills (notably communication and teamwork) and worsening mood when fatigued. CONCLUSIONS: Based on this scoping review, fatigue is a prevalent a phenomenon that anaesthesia providers cannot ignore. A combination of deterioration in non-technical skills, increased medication errors, loss of sustained attention, and psychomotor decline can lead to poorer performance and cause patient harm. Concrete strategies to mitigate fatigue should be developed.

ABSTRACT

BACKGROUND: In an effort to enhance accuracy of diagnosis of Schistosoma haematobium, this study explores day-to-day variability and diagnostic performance of real-time PCR for detection and quantification of Schistosoma DNA compared to other diagnostic tools in an endemic area before and after treatment. METHODOLOGY: Previously collected urine samples (N = 390) from 114 preselected proven parasitological and/or clinical S. haematobium positive Kenyan schoolchildren were analyzed by a Schistosoma internal transcribed spacer-based real-time PCR after 14 years of storage. Pre-treatment day-to-day fluctuations of PCR and microscopy over three consecutive days were measured for 24 children using intra-class correlation coefficient. A combined 'gold standard' (PCR and/or microscopy positive) was used to measure sensitivity and negative predictive value (NPV) of several diagnostic tools at baseline, two and 18 months post-treatment with praziquantel. PRINCIPAL FINDINGS: All 24 repeatedly tested children were PCR-positive over three days with little daily variation in median Ct-values, while 83.3% were found to be egg-positive for S. haematobium at day 1 and 75.0% at day 2 and 3 pre-treatment, signifying daily fluctuations in microscopy diagnosis. Of all 114 preselected schoolchildren, repeated microscopic measurements were required to detect 96.5% versus 100% of positive pre-treatment cases by single PCR. At two months post-treatment, microscopy and PCR detected 22.8% versus 69.3% positive children, respectively. Based on the 'gold standard', PCR showed high sensitivity (>92%) as compared to >31% sensitivity for microscopy, both pre- and post-treatment. CONCLUSIONS/SIGNIFICANCE: Detection and quantification of Schistosoma DNA in urine by real-time PCR was shown to be a powerful and specific diagnostic tool for detection of S. haematobium infections, with less day-to-day variation and higher sensitivity compared to microscopy. The superior performance of PCR before, and two and 18 months post-treatment provides a compelling argument for PCR as an accurate and reproducible tool for monitoring treatment efficacy.
