This systematic review had a clear focused question with the consideration of population, intervention and outcomes using PICO formula. The PICO question is P: healthcare provider (nurses, allied health professionals, doctors), I: effect of shift length 8h , O: 1-quality of patient care . (errors, patient injury, and nurses' perception of the quality of care). 2- Outcomes of healthcare providers . (overall wellbeing, fatigue, drug/alcohol use, stress, physical/mental health complaints and job satisfaction). To answer this review question, the authors have clearly defined their inclusion criteria including the type of studies. Randomised control trial, clinical trials and observational studies (cohort, case-control, cross-sectional and survey design were included in this review which are appropriate designs to provide the answer of this review question. Randomised controlled trials have been recognised as the best available evidence due to the use of measures that limit bias (Counsell, 1997). As a result, they are more likely to produce valid evidence concerning the effectiveness of an intervention (Bhandari and Tornetta, 2008; Sackett and Wennberg, 1997; Cochrane, 1979; Schlosser and Raghavendra, 2004; Sibbald and Roland, 1998). Therefore, it is going to provide the author with the best conclusion. In observational studies, an assessment and investigation of the relationship between the intervention and the outcome measure is made. Moreover, in this type of study the researcher is examining the intervention and observes the outcome (Bennett and Emberson). Thus, the types of the included studies in this review have appropriate designs to answer the review question.
