Background/Aims: Despite the high burden and frequency of urticaria, its epidemiology is not well known. We investigated the epidemiology of various type of urticaria in Korea and changes in its annual prevalence over 5 years. Methods: We used data from the 2010 to 2014 Health Insurance Review and Assessment database, which covers the claims of 97.0% of the South Korean population. Patients aged > 10 years old were included in this study. The presence of urticaria was identified on physician-certified diagnoses using the International Classification of Diseases 10th Revision (ICD-10) codes that include various type of urticaria (L500-L509) and angioedema (T783)...

BACKGROUND: Most cardiovascular disease risk prediction equations in use today were derived from cohorts established last century and with participants at higher risk but less socioeconomically and ethnically diverse than patients they are now applied to. We recruited a nationally representative cohort in New Zealand to develop equations relevant to patients in contemporary primary care and compared the performance of these new equations to equations that are recommended in the USA. METHODS: The PREDICT study automatically recruits participants in routine primary care when general practitioners in New Zealand use PREDICT software to assess their patients' risk profiles for cardiovascular disease, which are prospectively linked to national ICD-coded hospitalisation and mortality databases...

BACKGROUND: Heparin-induced thrombocytopenia can be a life-threatening and limb-threatening complication of heparin therapy. Incidence and complication rates of this condition have been extrapolated from studies with modest sample sizes, and despite the availability of therapeutic interventions the outcomes of heparin-induced thrombocytopenia are not well understood. We aimed to estimate disease burden, complication rates, and costs of heparin-induced thrombocytopenia in the USA. METHODS: In this population-based study we analysed data from 2009 to 2013 from the Nationwide (National) Inpatient Sample (NIS), a large, all-payer inpatient health-care database in the USA...

BACKGROUND: The switch from International Classification of Diseases, Ninth Revision, Clinical Modification to International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) for coding of inpatient procedures in the United States increased the number of procedural codes more than 19-fold, in large part due to the addition of laterality. We examined ICD-10-PCS codes for pairs of mirror-image procedures that are surgically equivalent. METHODS: We developed an algorithm in structured query language (SQL) to identify ICD-10-PCS codes differing only by laterality...

BACKGROUND: Accurate risk adjustment is the key to a reliable comparison of cost and quality performance among providers and hospitals. However, the existing case-mix algorithms based on age, sex, and diagnoses can only explain up to 50 percent of the cost variation. More accurate risk adjustment is desired for provider performance assessment and improvement. OBJECTIVE: To develop a case-mix algorithm that hospitals and payers can use to measure and compare cost and quality performance of their providers...

Introduction Systemic lupus erythematosus (SLE) is a complex disease that is associated with significant mortality and an increased risk of hospitalization. Several validated instruments are available to measure disease activity in SLE patients. However, these instruments were not designed to screen for SLE patients at an increased risk of hospitalization. These instruments also fail to incorporate some data that are easily obtainable from electronic health records, such as the frequency of missed outpatient appointments...

BACKGROUND: The article introduces Programs for Injury Categorization, using the International Classification of Diseases (ICD) and R statistical software (ICDPIC-R). Starting with ICD-8, methods have been described to map injury diagnosis codes to severity scores, especially the Abbreviated Injury Scale (AIS) and Injury Severity Score (ISS). ICDPIC was originally developed for this purpose using Stata, and ICDPIC-R is an open-access update that accepts both ICD-9 and ICD-10 codes. METHODS: Data were obtained from the National Trauma Data Bank (NTDB), Admission Year 2015...
