This dataset contains the statewide number and (unadjusted) rate for all-cause, unplanned, 30-day inpatient readmissions in California hospitals from 2011 to 2016 (contains first three quarters for Year 2015). Data are categorized by age, sex, race/ethnicity, expected payer and county.

California’s overall 30-day readmission rate has declined from 14% in 2011 to 13.5% in 2015.[1] The rate of unplanned hospital readmissions is an important measure of clinical quality. High rates may indicate concerns with low quality and are associated with high costs.[2] Fortunately, there is evidence that hospital readmission rates can be reduced using tested quality improvement methods.[3] Typically, these interventions involve system transformation. Coordinating care between in-patient, outpatient, home, and community settings is a key component of high quality health systems.[3] Patients’ demographic and economic status, social support structure, and multiple health conditions can increase or decrease the likelihood of being readmitted; though these impacts are not fully understood. Note that this indicator is not risk-adjusted and differs in some ways from the Centers for Medicaid and Medicare Services (CMS) measure. Data are categorized by age, sex, race/ethnicity, expected payer source, and county of residence. (See metadata below for further details.)
