Fourth-year medical students' experiences of diagnostic consultations in a simulated primary care setting

OBJECTIVES

The aim was to explore the experiences of fourth-year medical students of diagnostic consultations in a simulated primary care setting, in order to gain an insight into the suitability of such simulated consultations for assessing the diagnostic reasoning skills of medical students.

METHODS

This single-centre study employed a qualitative, cross-sectional design. Twelve fourth-year medical students volunteered to be filmed across 21 simulated, primary care consultations. The setting closely resembled OSCE stations, with a clinician present at each station monitoring the students' performance using a station-checklist. Upon completion of each station, participants reflected on their experiences using video-stimulated recall. Interviews were transcribed and analysed using Interpretative Phenomenological Analysis.

RESULTS

The simulated scenarios were often perceived to have limited fidelity with predictable outcomes. At times, preoccupation with the assessment checklist meant that students were more likely to focus on asking questions than interpreting the information they were gaining. Some students felt scrutinized during the consultations, while others struggled to adapt to the time pressure. Overall, the artificial setting seemed to promote a reductionist diagnostic approach and an attitude of 'ticking boxes' rather than engaging in active diagnostic reasoning.

CONCLUSIONS

The present findings call into question the assumption that observation-based assessment of the performance of medical students during simulated consultations can be reliably used to assess their diagnostic skills. Future studies need to explore how current assessment modalities could be better adapted to facilitate active engagement in diagnostic reasoning.

Potential cost savings by minimisation of blood sample delays on care decision making in urgent care services

Background

Timely availability of blood sample results for interpretation affects planning and delivery of patient care from initial assessment in Accident and Emergency (A&E) departments.

Materials and methods

Rates of, and reasons for, rejected blood samples submitted from all clinical areas over one month were evaluated. Haemoglobin (Hb) represented haematology and potassium (K⁺), biochemistry. A prospective observational study evaluated the methodology of sample collection and impact on utility.

Results

16,061 haematology and 16,209 biochemistry samples were evaluated; 1.4% (n = 229, range 0.5–7.3%) and 4.7% (n = 762, range 0.9–14%) respectively were rejected, with 14% (n = 248/1808) K⁺ rejection rate in A&E. Patients with rejected K⁺ and Hb had a longer median in-hospital stay of 9 and 76 h respectively and additional stay fixed costs of £26,824.74 excluding treatment. The rejection rate with Vacutainer and butterfly (4.0%) was lower than Vacutainer and cannula (28%).

Conclusion

Sample rejection rate is high and is associated with increased in-hospital stay and cost. Blood sampling technique impacts on rejection rates. Reduction in sample rejection rates in emergency care areas in acute hospitals has the potential to impact on patient flow and reduce cost.

Conclusion

•

Blood sample rejection rate in a single large NHS Foundation Trust is high.

•

The highest rate of blood sample rejection is in the Accident and Emergency department.

•

Blood sample rejection is associated with increased in-hospital stay.

•

Blood sampling technique impacts on rejection rates.

•

Reduction in sample rejection rates in emergency care areas in acute hospitals has the potential to impact on patient flow and cost.

Improved outcomes of high-risk emergency medical admissions cared for by experienced physicians

BACKGROUND

Physician experience has been shown to improve clinical outcomes. Limited numbers of experienced clinicians make it unfeasible that they would care for all patients. We hypothesized that physician experience would impact outcomes for patients with high, but not low, risk of mortality.

METHODS

All emergency admissions from 2002 to 2013 were studied. Two groups at low and high risk for mortality (1.3% (95% CI: 1.13, 1.62) vs. 19.4% (95% CI: 18.5, 20.3)) were defined by a risk prediction method comprising acute Illness Severity Score, Charlson Comorbidity Index and sepsis status. Length of stay (LOS) and 30-day in-hospital mortality were the primary end points. Consultant experience was studied univariately and also entered into a multiple logistic regression model to predict 30-day in-hospital survival. A zero-truncated Poisson regression model assessed LOS and incidence rate ratios (IRR) were calculated.

RESULTS

Over the 12-year study period 66 933 admissions were recorded in 36 271 patients. High-risk patients cared for by more experienced (≥20 years qualified) physicians had a lower 30-day in-hospital mortality (19.4 vs. 17.1% P < 0.001), relative risk reduction 11.9%. The multivariable odds ratio of a 30-day in-hospital death for an experienced physician was 0.89 (95% CI: 0.82, 0.97; P = 0.009). LOS was shorter for high-risk patients allocated to experienced physicians with a multivariable IRR of 0.77 (95% CI: 0.94, 0.99; P = 0.02). No difference in outcomes was found for low-risk patients.

CONCLUSION

High-risk but not low-risk patients have improved outcomes when cared for by physicians with greater experience.

Improving emergency department management of paediatric clavicle fractures: a complete audit cycle

A protocol was devised to address the issue of unnecessary attendance at fracture clinic by children who have a fracture of the clavicle that is deemed to be uncomplicated. For the purposes of this protocol, the clavicle was divided into three zones. Fractures of the middle clavicle for which displacement was minimal, heal quickly in the majority of cases, without the need for follow up. As a result these children can be discharged provided the parents are adequately advised. This article outlines a study which investigated the effectiveness of the protocol. The study found that implementation of the protocol reduced unnecessary attendance at clinic from 85% (47/55) to 17% (4/23). This resulted in cost savings to the trust and reduced the pressure on staff working in busy fracture clinics.

Consultant experience as a determinant of outcomes in emergency medical admissions

BACKGROUND

There are little data on the experiential learning of certified consultant specialists and outcomes in acute medicine. We have examined the 30-day in-hospital mortality and hospital length of stay (LOS) in relation to practice duration, using a database of emergency admissions.

METHODS

All emergency admissions (60,864 episodes in 35,168 patients) over eleven years (January 2002 to December 2012) were evaluated. Consultant staff were categorised by duration of clinical practice as <15 years, 15-20 years, >20≤25 years and >25 years. We used a stepwise logistic regression model to predict 30-day in-hospital death, adjusting risk estimates for major predictor variables. Marginal analysis used adjusted predictions to test for interactions of key predictors, while controlling for other variables.

RESULTS

Thirty-day in-hospital mortality correlated with time in clinical practice; decreasing from 8.9% and 9.1% with <15 and 15-20 years to 7.7% for each of the categories of >20≤25 years and >25 years. There was a progressive shortening of LOS with extent of clinical practice - from a median 5.0 days (IQR 1.8, 10.3) for consultants within 15 years of registration to 4.6 (IQR 1.7-8.9; p<0.05) at >20≤25 years and 4.4 (IQR 1.7-9.0; p<0.01) with >25 years. Duration of clinical practice predicted mortality in the univariable analysis - odds ratio (OR) 0.85 (95% CI: 0.78, 0.91; p<0.001); when adjusted in a multivariable model, it remained independently predictive--OR 0.87 (95% CI: 0.79, 0.96; p<0.001) for 30-day in-hospital mortality.

CONCLUSION

Certified specialists appear to continue with experiential learning with evidence of improved outcome after 20 years in clinical practice.
