Fatal heart block following treatment with botulinum toxin for achalasia

CCS diagnosis category 139) versusregional enteritis and ulcerative colitis (IBD, single-level CCS diagnosis category 144) based on age, sex, income, location, and region, while using the same query for all hospital stays as controls. These two diagnoses were chosen because of the known lower socioeconomic status and later onset of ulcer patients (epidemiology ofHelicobacter pylori ) and anticipated inverse trends for IBD. All hospital stays (discharges) were used as controls to ascertain that socioeconomic differences between the two diseases are not just due to lower socioeconomics of the first, but also to the higher than average socioeconomic status of patients with IBD. Abbreviated results are shown in Table 1 (while the reader is invited to run detailed queries on HCUPnet). As anticipated, IBD is characterized by earlier onset/need for hospitalization, and does affect a higher socioeconomic group. Regional differences (Northeast vs South) may also be a function of socioeconomic differences. Sex distribution in both diagnosis was very similar (not shown)—about 43% male and 57% female, and closely approximated all hospital stays.
