Background Inpatient training is a key component of gastroenterology (GI) fellowship programs nationwide, yet little is known about perceptions of the inpatient training experience. Aim To compare the content, objectives and quality of the inpatient training experience as perceived by program directors (PD) and fellows in US ACGME-accredited GI fellowship programs. Methods We conducted a nationwide, online-based survey of GI PDs and fellows at the conclusion of the 2016 academic year. We queried participants about (1) the current models of inpatient training, (2) the content, objectives, and quality of the inpatient training experience, and (3) the frequency and quality of educational activities on the inpatient service. We analyzed five-point Likert items and rank assessments as continuous variables by an independent t test and compared proportions using the Chi-square test. Results Survey response rate was 48.4% (75/155) for PDs and a total of 194 fellows completed the survey, with both groups reporting the general GI consult team ([90%) as the primary model of inpatient training. PDs and fellows agreed on the ranking of all queried responsibilities of the inpatient fellow to develop during the inpatient service. However, fellows indicated that attendings spent less time teaching and provided less formal feedback than that perceived by PDs (p \ 0.0001). PDs rated the overall quality of the inpatient training experience (p \ 0.0001) and education on the wards (p = 0.0003) as better than overall ratings by fellows. Conclusion Although GI fellows and PDs agree on the importance of specific fellow responsibilities on the inpatient service, fellows report experiencing less teaching and feedback from attendings than that perceived by PDs. Committing more time to education and assessment may improve fellows' perceptions of the inpatient training experience.

“…The criteria for item rejection was based on univariate skew and kurtosis characteristics and absolute skew values equal to, or greater than 3 and absolute kurtosis values of equal to, or greater than 10, based on the non-normality cut-off recommendations of Kline (2005). Statistical analysis for all quantitative studies in this thesis were conducted using PASW version 18 (SPSS, 2009a,b), Analysis of Moment Structures (AMOS) version 18 (Arbuckle, 1995(Arbuckle, -2009) and Mplus version 3 (Muthen & Muthen, 1998-2004.…”

“…All structural equation modeling analyses were performed on polychoric correlation matrices using Mplus (version 7.0; Muthén & Muthén, 2012) with the WLSMV estimator for categorical variables. This estimator estimates models with missing data (there were approximately 5% of missing responses in the present study) based on the full sample (n = 1416) and the full information that is available using pairwise present methods (see Asparouhov & Muthén, 2010).The choice to rely on WLSMV estimation is linked to the fact that this estimator is more suited to the ordered-categorical nature of Likert scales than traditional maximum likelihood estimation (Beauducel & Herzberg, 2006;Finney, & DiStefano, 2006;Lubke & Muthén, 2004).…”
