In the Original Investigation titled “Patterns of Hospital Utilization for Head and Neck Cancer Care: Changing Demographics” posted online in the January 29, 2015, issue of JAMA Otolaryngology–Head & Neck Surgery (doi:10.1001/jamaoto.2014.3603), information was copied within sections and text rearranged to accommodate Continuing Medical Education quiz formatting. The information from the topic statements of each paragraph in the Hypothesis Testing subsection of the Methods section was collected in a new first paragraph for that subsection, which reads as follows: “Several hypotheses regarding the causes of regionalization of HNCA care were tested using the NIS data: (1) increasing patient comorbidities over time, causing a shift in care to teaching institutions that would theoretically be better equipped to handle such increased comorbidities; (2) shifting of payer status; (3) increased proportion of prior radiation therapy; and (4) a higher fraction of more complex procedures being referred and performed at teaching institutions.” In addition, the phrase “As summarized in Table 3,” was added to the beginning of paragraph 6 of the Discussion section, and the callout to Table 3 in the middle of that paragraph was deleted. Finally, paragraphs 6 and 7 of the Discussion section were combined.
