The educational value of situational judgement tests (SJTs) when used during undergraduate medical training: A systematic review and narrative synthesis.

INTRODUCTION: Situational judgement tests (SJTs) are a recognised assessment method for admission into medical school, selection into postgraduate training programs, and postgraduate competency assessment. More recently, however, SJTs have been used during undergraduate medical training (UMT). This systematic review identifies, describes, and appraises the evidence for SJTs in UMT to determine educational associations and outcomes. METHODS: MEDLINE, EMBASE, ERIC, PsycINFO, SCOPUS, Web of Science, and grey literature were searched for original research studies evaluating SJTs implemented within UMT to 1 November 2022. Studies reporting evaluation outcomes were included. Narrative data syntheses were undertaken. Risk of Bias was appraised using the Quality in Prognosis Studies tool. RESULTS: 24 studies were included. National database-derived SJTs (n = 14) assessed against professionalism, postgraduate attainment, construct of medical degree, medical school admissions scores, personality attributes, and declaration of disability. In-house derived SJTs (n = 10) assessed against professionalism, clinical skills, and personality attributes. Most evidence evaluated and reported inverse SJT associations with professionalism and were moderate risk of bias. CONCLUSION: SJTs may have utility for developing professional behaviours in medical students. However, further research testing SJT robustness, standard setting methodologies, and prospectively evaluating SJTs against objective outcome measures within the context of UMT is warranted.

Weight loss in orthognathic surgery: a clinical study.

OBJECTIVE: To analyse weight change, body composition change and Body Mass Index change in patients undergoing orthognathic surgery. DESIGN: A service evaluation was undertaken in orthognathic patients pre-operatively and at 4 weeks post-surgery. SETTING: Queen Elizabeth Hospital Birmingham outpatient department. SUBJECTS: Thirty-one patients scheduled for single- or two-jaw orthognathic surgery and rigid internal fixation. METHODS: Immediately pre-operatively and at 4 weeks post-surgery the following information was gathered: (1) patient height; (2) patient weight (kg); (3) Patient Body Mass Index; and (4) patient body fat percentage. RESULTS: In the 4-week post-operative period, the average weight loss was -4·96 kg (range: -9·6 to +3·0 kg), with a body fat reduction of -3·07% (range: -5·80% to +2·30%) and an average reduction in Body Mass Index of -1·63 (range: -3·4 to +0·8). There was no statistically significant difference in weight loss (P = 0·1562) or body fat composition change (P = 0·2391) between single- or two-jaw surgery. There was no statistically significant difference in weight loss (P = 0·4858) or body fat composition change (P = 0·5321) between male and female patients. CONCLUSIONS: Weight loss observed was similar to that reported in studies using inter-maxillary fixation. Closer psychological and dietetic support is needed for patients who have a low normal or underweight Body Mass Index. Better and more bespoke tailored Oral Nutritional Supplementation must be provided for all orthognathic surgery patients to potentially reduce this significant weight loss.
