RESUMEN
Quality improvement (QI) is a core competency for Pediatric Hospital Medicine (PHM) and required for maintenance of certification, but many hospitalists lack QI training. This project set out to increase a PHM faculty's QI knowledge and comfort participating in QI projects, while concurrently applying the skills learned to a QI project in the hospital. METHODS: We designed a 4-session curriculum utilizing principles of adult learning. Faculty immediately applied learned concepts to a QI project to increase the percentage of patients who were seen by an attending and billed for on the same day as admission to the PHM service. Attitudinal data and scores on the validated Quality Improvement Knowledge Application Tool- Revised knowledge assessment were compared precurriculum and postcurriculum. A manifest content analysis was carried out for qualitative questions. RESULTS: Twenty faculty (83%) completed the preassessment; 15 (63%) completed the postassessment. Respondents showed statistically significant improvements in their perceived ability to participate in QI projects and their Quality Improvement Knowledge Application Tool- Revised scores. The group completed a QI project that increased revenue for the division. Faculty appreciated that the curriculum was applied to a real QI project and felt they would use the new skills in their daily practice. DISCUSSION: This curricular model based on adult learning theory, with immediate application to a real QI project, conclusively showed attitudinal, knowledge-based, and hospital system-level improvements, and was well received by faculty.
RESUMEN
OBJECTIVE. The contrast-enhanced ultrasound (CEUS) imaging features of hepatic vascular tumors in infants, including infantile hemangioma (IH) and congenital hemangioma (CH), are not well reported. Frequent inaccurate use of lesion terminology in the literature has created diagnostic confusion. The purpose of this study is to describe the CEUS features of IH and CH. MATERIALS AND METHODS. Ten patients, ranging in age from 8 days to 16 months, with hepatic vascular tumors were included for retrospective analysis. Gray-scale ultrasound, color Doppler ultrasound, and CEUS features were reviewed, and interobserver kappa coefficients were calculated. Final diagnoses were clinically determined by a pediatrician with expertise in vascular anomalies except in one patient who underwent surgical excision. RESULTS. Of the 10 patients, five had CHs and five had IHs. All 10 lesions were hyperenhancing in the early arterial phase. In the portal venous phase, four of five (80%) CHs showed hyperenhancement relative to normal liver parenchyma, whereas four of five (80%) IHs showed isoenhancement. In the late phase, washout of contrast material was seen in three of five (60%) IHs, whereas one IH remained isoenhancing and one IH was hyperenhancing. None of the CHs showed late washout. Interobserver kappa coefficients for CEUS features ranged from 0.60 to 1.00. CONCLUSION. Except for the CEUS feature portal venous phase enhancement (κ = 0.60), good to excellent (κ = 0.74-1.00) agreement about CEUS features of IHs and CHs was observed. A significant proportion of IHs (60%) showed washout at delayed phase imaging, which has also been reported with malignancies. Recognition of the overlap in imaging appearance of these two entities is vital to preventing misdiagnosis of malignancy.
