Has inpatient hospital treatment before and after age 65 changed as the difference between private and Medicare payment rates has widened?
This study examined whether inpatient hospital treatment before and after age 65 changed as the difference between private and Medicare payment rates widened. Using a large discharge dataset covering the period 2001-2011, the investigators tracked changes at age 65 in multiple dimensions of hospital care.

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.

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.
