This article investigates the current use of case studies in the teaching of Operational Research (OR) in the UK: how and where they are used; how they are developed; and whether there is an interest in training this area. It is aimed at lecturers teaching OR who are using or planning to use case studies in their teaching. It may also be of interest to policy-makers who wish to know what is being done in OR. The article focuses on the results of a survey sent to lecturers of OR in higher education in the UK. These are combined with an examination of the literature on using case studies in teaching in general and a small number of specific examples of how case studies are used in OR teaching. Case studies are included in OR teaching in a variety of ways and to develop a range of skills; particularly the ability to transfer academic knowledge to real-life contexts. The article identifies that the most significant barrier to the use of case studies in OR teaching is the development of new case studies; suggestions are made to address this, including providing training and collaboration opportunities. Overall this article provides an assessment of the ways in which case studies are used in OR; the advantages and limitations of using them; and specific examples of their use which will provide ideas to assist in improving OR teaching.

Background: There is a growing expectation that consultant-level doctors should be present within an ED overnight. However, there is a lack of robust evidence substantiating the impact on patient waiting times, safety or the workforce.Objectives: To evaluate the impact of consultant-level doctors overnight working in ED in a large university hospital.Methods: We conducted a controlled interrupted time series analysis to study ED waiting times before and after the introduction of consultant night working. Adverse event reports (AER) were used as a surrogate for patient safety. We conducted interviews with medical and nursing staff to explore attitudes to night work.Results: The reduction seen in average time in department relative to the day, following the introduction of consultant was non-significant (-12 min; 95% CI -28 to 4, p=0.148). Analysis of hourly arrivals and departures indicated that overnight work was inherited from the day. There were three (0.9%) moderate and 0 severe AERs in 1 year. The workforce reported that night working had a negative impact on sleep patterns, performance and well-being and there were mixed views about the benefits of consultant night presence. Additional time off during the day acted as compensation for night work but resulted in reduced contact with ED teams.Conclusions: Our single-site study was unable to demonstrate a clinically important impact of consultant night working on total time patients spend in the department. Our analysis suggests there may be more potential to reduce total time in department during the day, at our study site. Negative impacts on well-being, and likely resistance to consultant night working should not be ignored. Further studies of night working are recommended to substantiate our results.
