Association of acute kidney injury with readmissions after hospitalization for acute exacerbation of chronic obstructive pulmonary disease: a population-based study.
This study examined the association between acute kidney injury (AKI) and readmission with hospitalization for acute exacerbation of chronic obstructive pulmonary disease (AECOPD). Retrospective, population-based cohort data was used from the HCUP State Inpatient Databases from seven states (Arkansas, California, Florida, Iowa, Nebraska, New York, and Utah) from 2010 through 2013. A total of 356,990 patients were identified as hospitalized for AECOPD. Median age was 71 years and 41.9% were male. Of those 7% had a concurrent diagnosis of AKI. Patients with AKI were found to have a significantly higher risk of 30-day all-cause readmission compared to those without AKI as well as a significantly higher risk of 90-day all-cause readmission, particularly for non-respiratory reasons. These reasons included sepsis, acute renal failure, and congestive heart failure.

Trends in pediatric hospitalizations and readmissions: 2010-2016.
In this study, the authors examined recent trends in pediatric hospitalizations and readmissions at a national level using data from the 2010-2016 Healthcare Cost and Utilization Project Nationwide Readmissions Database and National Inpatient Sample. The investigators concluded that pediatric admissions declined from 2010 to 2016 as 30-day readmission rates increased. The increase in readmission rates was associated with greater numbers of admissions for children with chronic conditions.

Readmissions following inpatient treatment for opioid-related conditions.
This study analyzed the relationship between hospital admission for inpatient drug detoxification and/or rehabilitation services and subsequent opioid-related readmission. The study used hospital inpatient discharge and emergency department visit data from the AHRQ Healthcare Cost and Utilization Project (HCUP) survey. The sample consisted of 329,037 patients from seven states with an opioid-related index hospitalization from March 2010 to September 2013. A relatively small percentage (19.4%) of patients received treatment for drug use during their hospital stay. Those patients that did receive treatment had a lower 90-day readmission rate than those patients who did not.

Annual report on health care for children and youth in the united states: focus on 30-day unplanned inpatient readmissions, 2009 to 2014.
The authors describe trends in unplanned 30-day all-condition hospital readmissions for children aged 1 to 17 years between 2009 and 2014. Using HCUP data, they found that the rate of readmission was essentially stable between 2009 and 2014. In 2009, the most common reason for readmission was sickle cell anemia, whereas in 2014 the most common reason was epilepsy. Pneumonia fell from the second to the sixth most common reason for readmission over this period. The authors suggest that their study provides a baseline assessment for examining trends in 30-day unplanned pediatric readmissions, an important quality metric as the provisions of the Children's Health Insurance Program Reauthorization Act and the Affordable Care Act are changed and implemented in the future.

Age-related differences in the rate and diagnosis of 30-day readmission after hospitalization for acute ischemic stroke.
The purpose of this study was to examine the age-related differences in rate and principal reason of 30-day readmissions in patients hospitalized for acute ischemic stroke. Results showed that, among 620,788 hospitalizations, advanced age was associated with a higher 30-day readmission rate after acute ischemic stroke. Compared with younger adults, older adults were more likely to be readmitted for non-stroke-related conditions.

Medicare Advantage and traditional Medicare hospitalization intensity and readmissions.
This study uses 2013 Healthcare Cost and Utilization Project hospital discharge data from 22 states to compare hospital cost, length of stay, and readmissions for Traditional Medicare and Medicare Advantage. The authors found that Medicare Advantage hospitalizations were substantially less expensive and shorter for mental health stays but costlier and longer for injury and surgical stays.

Mental health conditions and unplanned hospital readmissions in children.
Mental health conditions (MHCs) are prevalent among hospitalized children and could influence the success of hospital discharge. The objective of this retrospective cross-sectional study was to assess the relationship between MHCs and 30-day readmissions. The investigators concluded that MHCs were associated with a higher likelihood of hospital readmission in children admitted for medical conditions and procedures. They suggest that understanding the influence of MHCs on readmissions could guide strategic planning to reduce unplanned readmissions for children with co-occurring physical and mental health conditions.

Returns to emergency department, observation, or inpatient care within 30 days after hospitalization in 4 states, 2009 and 2010 versus 2013 and 2014.
This study described trends in rates of 30-day, all-cause, unplanned returns to the hospital, including returns for observation stays and ED visits. Increases in observation and ED visits coincided with declines in readmissions for private insurance and Medicare. Return rates rose among patients with Medicaid and the uninsured.

All-payer analysis of heart failure hospitalization 30-day readmission: comorbidities matter.
In this study, the researchers investigated readmission characteristics and the magnitude of 30-day hospital readmissions after hospital discharge for heart failure using the Healthcare Cost and Utilization Project State Inpatient Databases (SID). They found in this large all-payer cohort, ∼70% of 30-day readmissions were for non-heart failure causes, and the median time to readmission was 12 days.

Revisit rates and associated costs after an emergency department encounter: a multistate analysis.
This study describes revisit rates, variation in revisit rates by diagnosis and state, and associated costs. It found that revisits after an index ED encounter are more frequent than previously reported, in part because many occur outside the index institution. Among ED patients in Florida, more resources are spent on revisits than on index ED visits.

Hospital length of stay and readmission: an early investigation.
This study is a retrospective examination of the association between length of stay in an index hospitalization and readmission within 7 days and within 30 days of discharge. It found negative associations between length of stay and readmission probability, particularly for heart attack patients; however, the magnitude of the effect was modest for heart attack.
