Because of a small bug in a piece of the software the authors used in their analysis script, the authors incompletely categorized a part (66%) of the “Dementia and Alzheimer’s” cause of death group and assigned it to the “other mental and behavioral disorders” cause of death category. Therefore, the description of the study population (Table 1) had incorrect numbers and percentages in these 2 categories. When correcting this error, the authors also obtained slightly different estimates in all the regression models that included cause of death categories, which also slightly affected the geographical maps based on adjusted multilevel models.
The revised Table 1 is now corrected (with bolded cells for revised numbers), as well as revised Figures 2–4, which are available in color online.
In addition, the following sentences of the result section also need to be corrected (changes in bold):
Coronary heart disease, external causes and other mental and behavioral diseases generated, on average, lower costs.
Model 2, which included only age and cause of death, reduced HSA-level variance by 46% for younger men and 21% for women, with smaller reductions achieved for older individuals (11% and 4%, respectively).
In contrast, also including language region resulted in a substantial reduction of HSA-level cost variability (model 4): compared with model 1 without any individual or regional characteristics, HSA-level variance was decreased by 95% for young males, 87% for females, 73% for older males, and 52% for females.
Finally, the Supplemental file (http://links.lww.com/MLR/B255) was corrected in all instances where the results have changed when using the correct categorization of cause of death.
The corrections listed above slightly modify their results; however, they do not change in any way the main conclusions and the message of the publication.
The authors wish to apologize for the error and any inconvenience it may have caused.
