We commend Dr Ford for the extensive analysis of inpatient admissions, ED visits, and readmissions for COPD and bronchiectasis in an article published in CHEST (April 2015). The National Inpatient Sample and online query system HCUPnet (http://hcupnet.ahrq.gov) were used by the author to generate 30-day readmission rates for adults (aged ≥ 18 years) with index hospitalizations for COPD or bronchiectasis (not associated with cystic fibrosis). Although the readmission rate analysis by the author was extensive, age was the only demographic described, and predictors of readmission were not identified due to a limitation of the HCUPnet system. We conducted a similar analysis using the Nationwide Readmissions Database for 2013, which includes 14 million discharges from 21 states, representing 49.1% of all US hospitalizations. We identified our index admissions as adults, with Clinical Classification Software diagnostic category 127 as their principal diagnosis, similar to Ford’s approach. We used the criteria for index admissions and 30-day readmissions as defined by the Centers for Medicare and Medicaid Services. We excluded patients who died during the index admission, as they were not at risk of readmission, as well as patients with index discharges in December, due to lack of sufficient time to capture 30-day readmissions, and patients with missing information on key variables. We also excluded patients who were not residents of the state of the index hospitalization, since readmission across state boundaries could not be identified in the Nationwide Readmission Database. Manufacturer-provided sampling weights were used to produce national-level estimates.
