Expanding Post-Discharge Readmission Metrics in Patients with Chronic Obstructive Pulmonary Disease

Year: 2020

Type: article

Abstract: BACKGROUND: Chronic obstructive pulmonary disease (COPD) is a common and costly reason for hospitalization and rehospitalization. The Hospital Readmissions Reduction Program penalizes hospitals for excess, non-elective, all-cause 30-day, inpatient rehospitalizations for COPD. We sought to determine how broadening the outcome definition would alter the numbers of patients being counted, specifically if observation stays and patients who died in the post-discharge period were included. METHODS: We performed a retrospective cohort study of patients hospitalized for COPD between July 1, 2010 and December 31, 2017 in 21 hospitals in the Kaiser Permanente Northern California health care system. We classified encounters into 3 outcomes groups based on a 30-day post-discharge observation period: Group (1) non-elective, all-cause, inpatient rehospitalizations, which is the current metric; Group (2) composite outcome of Group 1 or all-cause mortality; and Group (3) composite outcome of Group 1 or non-elective, all-cause, observation rehospitalization. We used the Box-Cox method to find the transformation of the cumulative curves that resulted in the smallest mean standard error. We used the slope of the transformed curve against days to test for significant differences between pairs of cumulative density curves. RESULTS: =0.02 comparing Groups 1 and 3). CONCLUSION: We show that adding outcomes such as mortality and observation rehospitalizations would change the counts of patients contributing to the Hospital Readmission Reduction Program penalty for COPD if the outcome were broadened. Including mortality or observation stays in the quality incentive program might incentivize hospitals and providers to prevent these events in addition to inpatient rehospitalizations.
