EDUCATIONAL INTERVENTION FOR IMPROVING THE APPROPRIATENESS OF TRANSTHORACIC ECHOCARDIOGRAMS ORDERED BY PEDIATRIC CARDIOLOGISTS

Abstract

OBJECTIVE The objective of this study was to evaluate effectiveness of educational intervention (EI) in the Pediatric Appropriate Use of Echocardiography (PAUSE) study to improve appropriateness of transthoracic echocardiograms (TTEs) ordered in pediatric cardiology clinics. DESIGN Data were prospectively collected after the publication of the Appropriate Use Criteria (AUC) document during 2 phases: the pre-EI phase (1/1/15 to 4/30/15) and the post-EI phase (7/1/15 to 10/30/15). Pre-EI, site-investigators (SI) determined AUC indications, by reviewing the clinic records. Post-EI, providers assigned indications prior to obtaining TTE. SETTING Pediatric cardiology clinics at six centers. PATIENTS Those ≤18 years old, receiving initial outpatient TTE. INTERVENTIONS EI included (i) sharing the pre-EI appropriateness ratings with providers, (ii) lecture on AUC, (iii) providers self-assigning indications, and (iv) monthly e-mail feedback by SI to individual providers. OUTCOME The primary outcome measure was a change in the proportion of studies for indications rated R following EI. RESULTS Of the 4542 TTEs (1907 pre-EI, 2635 post-EI) ordered by 90 physicians, overall comparison of appropriateness ratings before and after EI showed an increase in Appropriate (72.5%-76.2%, P = .004), no change in May Be Appropriate, and a decline in Rarely Appropriate (R) from 9.6% to 7.4%, P = .008. Following EI, a significant decline in R was observed only in three centers and EI did not affect the variation in TTEs ordered for R indications among physicians (P = .467). Physicians with the highest proportion of TTEs ordered for R before EI, showed the most significant decline in R. CONCLUSIONS Appropriateness of pediatric outpatient TTE varies substantially by center. A customized EI resulted in modest improvement in the appropriateness of TTEs in the PAUSE study, with an increase in Appropriate and a decrease in R TTEs. Multifaceted EIs are required to improve adherence to national standards such as AUC.
