We assessed the relationship between hospitals' diagnosis diversity and cost per hospitalization for children. Retrospective analysis of 1 654 869 all-condition hospitalizations for children ages 0 to 21 years from 2816 hospitals in the Kids' Inpatient Database 2016. Mean hospital cost per hospitalization, Winsorized and log-transformed, was assessed for freestanding children's hospitals (FCHs), nonfreestanding children's hospitals (NFCHs), and nonchildren's hospitals (NCHs). Hospital diagnosis diversity index (HDDI) was calculated by using the D-measure of diversity in Shannon-Wiener entropy index from 1254 diagnosis and severity-of-illness groups distinguished with 3M Health's All Patient Refined Diagnosis Related Groups. Log-normal multivariable models were derived to regress hospital type on cost per hospitalization, adjusting for hospital-level HDDI in addition to patient-level demographic (eg, age, costs of inpatient care for pediatric patients.Disagreements, including those between residents and attending physicians, are common in medicine. In this Ethics Rounds article, we present a case in which an intern and attending disagree about discharging the patient; the attending recommends that the patient be hospitalized longer without providing evidence to support his recommendation. Commentators address different aspects of the case. The first group, including a resident, focus on the intern's potential moral distress and the importance of providing trainees with communication and conflict resolution skills to address inevitable conflicts. The second commentator, a hospitalist and residency program director, highlights the difference between residents' decision ownership and attending physicians' responsibilities and the way in which attending physicians' responsibilities for patients can conflict with their role
