Reducing the use of plain abdominal radiographs in an emergency department

Appropriateness of adult plain abdominal radiograph requesting in a regional Emergency Department

INTRODUCTION

Although commonly ordered, abdominal x-rays are thought to be overused and unhelpful in many emergency department patients. Our objectives were to evaluate the appropriateness of plain abdominal X-ray (AXR) requests in adult patients presenting to a Victorian regional emergency department (ED).

METHODS

A retrospective chart review was performed of all adult patients with a plain AXR requested by ED medical staff members in a regional healthcare centre in Victoria, Australia in 2016. Patient demographics, ED disposition and any further imaging results were extracted from the medical record. Indications for X-ray and clinician seniority were determined from the radiology request slips signed by the treating emergency doctor. Appropriateness of imaging was determined by comparing the indication for abdominal radiograph to local evidence-based guidelines.

RESULTS

One hundred and nine episodes of plain AXR requests met the inclusion criteria. Of these, 40 were considered inappropriate according to clinical guidelines. Overall, 36% (39/109) had normal or non-specific findings and 42% (46/109) demonstrated faecal loading, while 22% (24/109) identified pathology. Thirty-three patients had further imaging, mostly with computed tomography (CT). Junior staff members were responsible for most of the AXR requests.

CONCLUSION

In our regional hospital ED, over one third of AXRs requested for adult patients were inappropriate according to clinical guidelines. AXRs have a low diagnostic yield and frequently do not reduce the need for further imaging. The use of a clinical practice guideline and education of junior medical staff may increase the appropriate use of plain AXRs in the regional ED setting.

Influence of educational, audit and feedback, system based, and incentive and penalty interventions to reduce laboratory test utilization: a systematic review

Laboratory and radiographic tests are often ordered unnecessarily. This excess testing has financial costs and is a burden on patients. We performed a systematic review to determine the effectiveness interventions to reduce test utilization by physicians. The MEDLINE and EMBASE databases were searched for the years 1946 through to September 2013 for English articles that had themes of test utilization and cost containment or optimization. Bibliographies of included papers were scanned to identify other potentially relevant studies. Our search resulted in 3236 articles of which 109 met the inclusion criteria of having an intervention aimed at reducing test utilization with results that could be expressed as a percent reduction in test use relative to the comparator. Each intervention was categorized into one or more non-exclusive category of education, audit and feedback, system based, or incentive or penalty. A rating of study quality was also performed. The percent reductions in test use ranged from a 99.7% reduction to a 27.7% increase in test use. Each category of intervention was effective in reducing test utilization. Heterogeneity between interventions, poor study quality, and limited time horizons makes generalizations difficult and calls into question the validity of results. Very few studies measure any patient safety or quality of care outcomes affected by reduced test use. There are numerous studies that use low investment strategies to reduce test utilization with one time changes in the ordering system. These low investment strategies are the most promising for achievable and durable reductions in inappropriate test use.

Plain abdomen radiographs: the right view?

BACKGROUND

Plain abdomen radiographs (PAR) have limited use in the setting of the emergency department. We conducted this study to look at the appropriateness of requests and its utilization in our emergency department.

METHODOLOGY

We conducted a retrospective analysis of scanned emergency department notes between the period of December 2005 and February 2006 (3 months). Those cases with PAR requested by an emergency department doctor were recruited in this study. The documented history, examination, and provisional diagnosis in the case notes were reviewed to look at the appropriateness of the indications for requests.

RESULTS

Only 67% (50 of 75) of the requests were appropriate according to the Royal College of Radiologists guidelines with bowel obstruction/paralytic ileus, renal colic and foreign body ingestion being the common presentations. Thirty three percent (25 of 75) (95% confidence interval: 24-45) of the requests were inappropriate and could have been avoided by referring to the aforementioned guidelines.

CONCLUSION

We recommend implementing strict local protocols and guidelines for requesting PAR to reduce inappropriate requests. We also recommend staff education and awareness programs for reducing the over-utilizing of PAR.

Information sharing can reduce laboratory use by emergency physicians

This study analyzed the effect information sharing through physician profiling would have on emergency physician behavior. It is a before-and-after audit of laboratory use in a community hospital. A 9-month control period was followed by a 15-month period in which the physicians' laboratory use was presented and discussed at monthly meetings. The laboratory use decreased 17.8%, from a mean of 2.36 studies per patient during the control period to 1.94 during the final quarter of the study. The actual laboratory costs per month decreased 17.7%, from a mean of $32,415 per month to $26,687 per month. There was only one possible adverse outcome out of 34,320 patients seen. There were no adverse changes in other quality improvement indicators. Information sharing can result in a decrease in the number and cost of laboratories studies ordered by emergency physicians without an adverse change in routine quality improvement indicators.

Teaching in accident and emergency medicine: 10 commandments of accident and emergency radiology

One of the many attractions of accident and emergency medicine is the wide and varied opportunities it provides for education. This is because of the acute nature of the work, which necessitates prompt and accurate decision making. However, in many instances the decisions have to be made by inexperienced senior house officers. Departments therefore need a safe system of practice that can be remembered and adhered to under stress. The 10 commandments is one such system for analysing emergency radiographs of all the regions of the body. This system lays down guidelines to protect both staff and hospitals from the inevitable mistakes that inexperienced doctors will make.
