New approach to undergraduate quality improvement

BACKGROUND

While quality improvement (QI) is an essential component to modern day clinical practice, some foundation doctors fail to engage. This is compounded by a lack of formalised undergraduate QI teaching. We trial an undergraduate active learning workshop and evaluate it using a concurrent triangulation mixed methods design.

APPROACH

We constructed a 2-hour interactive QI workshop utilising near-peer educators for third year undergraduate medical students. Our workshop demonstrated an exemplary project and a template featuring evidenced-based QI tools to grasp key concepts. Informal support was provided for student QI projects, undertaken in small peer groups. Utility was assessed using linked pre-and-post event questionnaires with Likert scales, free text thematic analysis and project completion rates.

EVALUATION

We recruited 74 students to attend our workshops delivered over 3 months. We achieved high event satisfaction and significant improvements on baseline confidence. Free text comments suggested students perceive QI as an important part of the undergraduate curriculum, described barriers to engagement and the value they place on project autonomy. The workshop eased student feelings of anxiety and intimidation regarding change ideas. Nine projects were completed with one winning a poster prize at a regional conference.

IMPLICATIONS

We demonstrate a popular resource light model that can be scaled up to a variety of centres. Targeting QI teaching at the undergraduate level may be instrumental in developing QI culture in health care systems and address barriers to postgraduate involvement. Our study furthers the understanding of undergraduate students' perspectives of QI and demand for further sessions.

Perioperative intravenous contrast administration and the incidence of acute kidney injury after major gastrointestinal surgery: prospective, multicentre cohort study

BACKGROUND

This study aimed to determine the impact of preoperative exposure to intravenous contrast for CT and the risk of developing postoperative acute kidney injury (AKI) in patients undergoing major gastrointestinal surgery.

METHODS

This prospective, multicentre cohort study included adults undergoing gastrointestinal resection, stoma reversal or liver resection. Both elective and emergency procedures were included. Preoperative exposure to intravenous contrast was defined as exposure to contrast administered for the purposes of CT up to 7 days before surgery. The primary endpoint was the rate of AKI within 7 days. Propensity score-matched models were adjusted for patient, disease and operative variables. In a sensitivity analysis, a propensity score-matched model explored the association between preoperative exposure to contrast and AKI in the first 48 h after surgery.

RESULTS

A total of 5378 patients were included across 173 centres. Overall, 1249 patients (23·2 per cent) received intravenous contrast. The overall rate of AKI within 7 days of surgery was 13·4 per cent (718 of 5378). In the propensity score-matched model, preoperative exposure to contrast was not associated with AKI within 7 days (odds ratio (OR) 0·95, 95 per cent c.i. 0·73 to 1·21; P = 0·669). The sensitivity analysis showed no association between preoperative contrast administration and AKI within 48 h after operation (OR 1·09, 0·84 to 1·41; P = 0·498).

CONCLUSION

There was no association between preoperative intravenous contrast administered for CT up to 7 days before surgery and postoperative AKI. Risk of contrast-induced nephropathy should not be used as a reason to avoid contrast-enhanced CT.

The prevalence of scabies, pyoderma and other communicable dermatoses in the Bijagos Archipelago, Guinea-Bissau

INTRODUCTION

Skin diseases represent a significant public health problem in most low and middle income settings. Nevertheless, there is a relative paucity of high-quality epidemiological data on the prevalence of these conditions.

MATERIALS/METHODS

We conducted two cross-sectional population-based skin-surveys of children (6 months to 9 years old) in the Bijagós Archipelago of Guinea-Bissau during the dry season (February-March 2018) and the wet season (June-July 2018). Following a period of training, a nurse performed a standardised examination for communicable dermatoses for each participant. We calculated the prevalence of each skin condition and investigated demographic associations.

RESULTS

1062 children were enrolled in the dry season survey of whom 318 (29.9%) had at least one skin diseases. The most common diagnosis was tinea capitis (154/1062, 14.5% - 95% CI 12.5-16.8%) followed by tinea corporis (84/1062, 7.9% - 95% CI 6.4-9.7%), pyoderma (82/1062, 7.7% - 95% CI 6.2-9.5%) and scabies (56/1062. 5.2% - 95%CI 4.0-6.8%). 320 children were enrolled in the wet season survey of whom 121 (37.8%) had at least one skin problem. Tinea capitis remained the most common diagnosis (79/320, 24.7% - 95% CI 20.1-29.9%), followed by pyoderma (38/320, 11.9% - 95% CI 8.6-16.1%), tinea corporis (23/320, 7.2% - 95% 4.7-10.7%) and scabies (6/320, 1.9% - 95% CI 0.8-4.2%).

CONCLUSIONS

Our study, which utilised robust population-based cluster random sampling methodology, demonstrates the substantial disease burden caused by common communicable dermatoses in this setting. Given these findings, there is a need to consider common dermatoses as part of Universal Health Coverage to deliver 'skin-health for all'.
