研究概览

简要总结

The main objective of this study is to evaluate the impact of the implementation of referral guidelines for imaging exams requested by the emergency department on exam relevance. The latter is assessed via the rate of suspected diagnoses that are confirmed by the requested exam.

详细描述

The secondary objectives of this study are to assess the impact of the implementation of referral guidelines for imaging exams requested by the emergency department on the following:

A. How exam results are classified in relation to the initial, suspected diagnosis.

B. Further aspects of exam relevance.

C. Delays associated with exams

D. Changes in practice in terms of type of examination, clinical situations, the number of tests ordered per patient, and emergency situations

结局指标

主要结局

时间窗: baseline (days 0 to 30) versus the 6th month after implementation of guidelines

Measured over an observation period of 1 month.

次要结局

  • Change in the frequency of each type of clinical situation associated with imaging exams.(baseline (days 0 to 30) versus the 6th month after implementation of guidelines)
  • Change in the % agreement between the clinical situation coded by the emergency doctor and the radiologist(baseline (days 0 to 30) versus the 6th month after implementation of guidelines)
  • Change in the % of requested exams that do not conform with the exam recommended by the implemented guidelines(baseline (days 0 to 30) versus the 6th month after implementation of guidelines)
  • Change in the % of exams performed identical to the exam requested(baseline (days 0 to 30) versus the 6th month after implementation of guidelines)
  • Change in the average delay between the time marked on the request and the distribution of written exam results.(baseline (days 0 to 30) versus the 6th month after implementation of guidelines)
  • Change in the number of requests for imaging exams made by the emergency department(baseline (days 0 to 30) versus the 6th month after implementation of guidelines)
  • Change in the positivity rate for each suspected diagnosis(baseline (days 0 to 30) versus the 6th month after implementation of guidelines)
  • Change in the frequency of imaging exams requested per type of emergency situation(baseline (days 0 to 30) versus the 6th month after implementation of guidelines)
  • Change in the frequency of injection of contrast agents(baseline (days 0 to 30) versus the 6th month after implementation of guidelines)
  • Change in the frequency of each type of exam carried out.(baseline (days 0 to 30) versus the 6th month after implementation of guidelines)
  • Change in the average number of imaging exams requested per patient(baseline (days 0 to 30) versus the 6th month after implementation of guidelines)
  • Change in the total radiation exposure per patient(baseline (days 0 to 30) versus the 6th month after implementation of guidelines)
  • Change in the average delay between the time marked on the request and the exam.(baseline (days 0 to 30) versus the 6th month after implementation of guidelines)
  • Change in the number of admissions in the emergency department(baseline (days 0 to 30) versus the 6th month after implementation of guidelines)
  • Change in the % of patients admitted to the emergency department and needing an imaging exam.(baseline (days 0 to 30) versus the 6th month after implementation of guidelines)
  • Change in the frequency of patients requiring contrast agents AND whose exam results are classified as "the suspected diagnosis was not confirmed, exam normal"(baseline (days 0 to 30) versus the 6th month after implementation of guidelines)
