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.

Selecting post-acute care settings after abdominal surgery: are we getting it right?
Using Nationwide Inpatient Sample data, the authors investigated whether variation in post-acute care (PAC) services could be explained by surgeons discharging clinically similar patients to different PAC destinations. They found considerable potential for reducing variation in PAC use and costs by better understanding how surgeons make decisions about PAC placement.

National landscape of unplanned 30-day readmissions in patients with left ventricular assist device implantation.
This study tracked unplanned 30-day readmissions in patients who had undergone left ventricular assist device (LVAD) implantation during 2013. Data from the Healthcare Cost and Utilization Project (HCUP) National Readmission Database was used. Out of 2,235 patients who had an LVAD implantation, 29.7% had at least 1 unplanned readmission within 30 days. The top reasons for readmission were implant complications (14.9%), congestive heart failure (11.7%), and gastrointestinal bleeding (8.4%). Predictors of readmission included a prolonged length stay during the primary admission, Medicare insurance, and discharge to a short-term facility.

Association of inferior vena cava filter placement for venous thromboembolic disease and a contraindication to anticoagulation with 30-day mortality.
Despite the absence of data from randomized clinical trials, professional societies recommend inferior vena cava (IVC) filters for patients with venous thromboembolic disease (VTE) and a contraindication to anticoagulation therapy. Prior observational studies of IVC filters have suggested a mortality benefit associated with IVC filter insertion but have often failed to adjust for immortal time bias. The purpose of this study was to determine the association of IVC filter placement with 30-day mortality after adjustment for immortal time bias.

Hospital and community characteristics associated with pediatric direct admission to hospital.
Researchers aimed to determine the relationships between hospital and community factors and pediatric direct admission rates, and to evaluate the degree to which these characteristics explain variation in risk-adjusted direct admission rates. Using HCUP data, they found that direct admission rates were associated with several hospital and community characteristics, but the majority of variation in hospitals' direct admission rates was not explained by these factors. They recommended that their findings suggest opportunities for diverse hospital types to develop the infrastructure and communication systems necessary to support pediatric direct admissions.

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.

Changes in hospital inpatient utilization following health care reform.
The purpose of this retrospective study was to estimate the effects of 2014 Medicaid expansions on inpatient outcomes using population and unemployment data from HCUP’s State Inpatient Databases. Outcomes included total admissions, referral-sensitive surgical and preventable admissions, length of stay, cost, and severity of patient illness. The authors conclude that Medicaid expansions did not change all-payer admission volumes, but expansions were associated with increased Medicaid and decreased uninsured volumes. The results of the study suggest that previously uninsured persons with a greater need for inpatient services were the most likely to gain coverage.

Trend of age-adjusted rates of pediatric traumatic brain injury in U.S. emergency departments from 2006 to 2013.
The objective of this study was to use the 2006(-)2013 Nationwide Emergency Department Sample (NEDS) database to describe trends of age-adjusted rates of pediatric traumatic brain injuries (TBI) treated in U.S. emergency departments. The investigators found that the overall age-adjusted rates of pediatric TBI-related emergency department (ED) visits increased from 2006 to 2013, which was largely caused by pediatric mild TBIs, especially unspecified injury to the head (ICD-9-CM code 959.01) and concussion.

Current state of empyema management.
The goal of this study was to examine current treatment practices and outcomes for inpatient treatment of empyema. A comprehensive, longitudinal data set from the New York State Inpatient Database, encompassing an entire state cohort of hospitalized patients, was used. The cohort included 4,095 patients who were undergoing intervention for primary empyema and were discharged 2009 to 2014 with chest tube, video-assisted thoracoscopic surgery (VATS) decortication and drainage, or open drainage and decortication. Patients were categorized into these three groups by definitive treatment during their initial hospitalization. The findings indicate that patients who were managed with chest tubes showed higher readmission and reintervention rates, suggesting that some of these patients may benefit from earlier definitive surgical intervention.

Mandatory physician reporting of at-risk drivers: the older driver example.
The hypothesis that mandatory physician reporting laws reduce the rate of crash-related hospitalizations among older adult drivers was tested. Mandatory physician reporting failed to explain any significant variation in crash hospitalization rates, when adjusting for other state-specific laws and characteristics. Vision testing at in-person license renewal was a significant predictor of lower crash hospitalization rate.

Epidemiologic patterns of in-hospital anaphylaxis in pediatric surgical patients.
This research letter looks into epidemiologic patterns of in-hospital anaphylaxis in pediatric surgical patients. Data from the study came from the Kids’ Inpatient Database (KIDS), which is released every 3 years. The data came from the 2003, 2006, 2009 and 2012 KID data sets. Children were included if they had a surgical admission for anaphylaxis which is interpreted as an in-hospital event. Overall in-hospital mortality for all children was 0.38% but for in-hospital anaphylaxis was 2.47%. The most common reason children were in the hospital before the event was hematological and myeloproliferative disorders, with the largest percentage undergoing bone marrow transplant procedures. Although the exact cause of the reaction was not known, hypersensitivity to chemotherapeutic agents and more recent mAb treatments have been identified as reasons for the in-hospital anaphylaxis.

Shifts in Medicaid and uninsured payer mix at safety-net and non-safety-net hospitals during the Great Recession.
The authors examined payer mix at safety-net hospitals (SNHs) and non-SNHs during a period covering the Great Recession using data from 38 states. The number of privately insured stays decreased at both SNHs and non-SNHs. Non-SNHs increasingly served Medicaid-enrolled and uninsured patients; in SNHs, the number of Medicaid stays decreased and uninsured stays remained stable.

Association between hospital financial distress and immediate breast reconstruction surgery after mastectomy among women with ductal carcinoma in situ.
Hospital financial distress may reduce the services a hospital can offer, particularly unprofitable ones. This study examined the association between hospital financial distress (HFD) and receipt of immediate breast reconstruction surgery after mastectomy among women diagnosed with ductal carcinoma in situ (DCIS). It concluded that the financial strength of the hospital where a patient receives treatment is associated with receipt of immediate breast reconstruction surgery.

Geography, not health system affiliations, determines patients' revisits to the emergency department.
This study sought to determine how frequently patients revisit the emergency department after an initial encounter, and to describe revisit capture rates for the same hospital, health system, and geographic region. Seventy percent of 30-day returns occurred to the same hospital. The 30-day return capture rates were highest within the same geographic area: county-level capture at 92 percent versus health system capture at 75 percent.

Population-based approaches to treatment and readmission after spinal cord injury.
Recent studies in surgical and non-surgical specialties have suggested that patients admitted on the weekend may have worse outcomes. It is unclear whether this extends to patients with spinal cord injury (SCI). This study was designed to evaluate factors for readmission after index hospitalization for spinal cord injury. The study’s results suggested that the weekend effect, described previously in other patient populations, may not play as important a role in patients with SCI.

Association of obesity with severity of heart failure exacerbation: a population-based study.
Researchers investigate the associations of obesity with severity of heart failure exacerbation and in-hospital mortality using population-based data from the State Inpatient Databases. Subjects were adults hospitalized for heart failure exacerbation in seven States from 2012 to 2013. The researchers found that, based on large population-based data sets of patients with heart failure exacerbation, obesity was associated with higher acute severity measures but lower in-hospital mortality.

Pediatric adverse event rates associated with inexperience in teaching hospitals: a multilevel analysis.
In this article, the investigators hypothesize that adverse event rates increase with the availability of more complex services and technologies (transplantation and pediatric open-heart surgery); increase as experience of providers decreases (July effect); and increase with residents per bed, a measure of both average provider inexperience and congestion. Using multilevel analysis, they found empirical evidence in support of their three hypotheses.

Reduced risk of acute exacerbation of COPD after bariatric surgery: a self-controlled case series study.
Little is known about the impact of weight reduction on chronic obstructive pulmonary disease (COPD)-related outcomes in patients who are obese. This study found that the risk of an ED visit or hospitalization for acute exacerbation of COPD substantially decreased after bariatric surgery in patients who are obese. This observation suggests the effectiveness of substantial weight reduction on COPD morbidity.

Dementia and motor vehicle crash hospitalizations: role of physician reporting laws.
This study sought to determine the effect of physician reporting laws and state licensing requirements on crash hospitalizations among drivers with dementia. It concluded that physician reporting laws, mandated or legally protected, were not associated with a lower likelihood of dementia among crash hospitalized drivers. Vision testing at in-person renewal and in-person renewal requirements were significantly related with a lower prevalence of dementia in hospitalized older drivers.
