BACKGROUND: Nordic countries are the primary source for nationwide data on the incidence of subarachnoid haemorrhage (SAH). Reliable estimates of national incidence rates of SAH in other countries are lacking, yet studies from Nordic countries with exceptional incidence rate are sometimes disregarded because of concerns regarding external validity. Autopsies are rarely performed for sudden deaths, therefore estimates of the SAH incidence commonly reflect the hospital discharge rates. Our aim was to estimate the nationwide incidence of non-traumatic SAH in Germany using a national hospital discharge register...

Recent literature suggests an increase in the incidence of acute kidney injury (AKI). We evaluated population-based trends of AKI over the course of nine years, using a validated electronic health record tool to detect AKI. All adult residents (18 years of age and older) of Olmsted County, Minnesota (MN), admitted to the Mayo Clinic Hospital between 2006 and 2014 were included. The incidence rate of AKI was calculated and temporal trends in the annual AKI incident rates assessed. During the nine-year study period, 10,283, and 41,847 patients were admitted to the intensive care unit or general ward, with 1,740 and 2,811 developing AKI, respectively...

OBJECTIVES: Readmission after surgery is a quality metric hypothesized to reflect the quality of care in the index hospitalization. We examined the link between readmissions and a surrogate of surgical quality - major postoperative complication - among ovarian cancer patients. METHODS: Patients who underwent surgery for ovarian cancer between 2012 and 2013 were identified from the National Surgical Quality Improvement Project (NSQIP). Major complications were defined as grade 3 or ≥complications on the validated Claviden-Dindo scale and included both NSQIP and non-NSQIP defined complications based on readmission ICD-9 code...

In 2015, the Society for Maternal-Fetal Medicine developed a low risk for cesarean delivery definition based on administrative claims-based diagnosis codes described by the International Classification of Diseases, Ninth Revision, Clinical Modification. The Society for Maternal-Fetal Medicine definition is a clinical enrichment of 2 available measures from the Joint Commission and the Agency for Healthcare Research and Quality measures. The Society for Maternal-Fetal Medicine measure excludes diagnosis codes that represent clinically relevant risk factors that are absolute or relative contraindications to vaginal birth while retaining diagnosis codes such as labor disorders that are discretionary risk factors for cesarean delivery...
