INTRODUCTION: Hypospadias surgery has progressed steadily over recent years. There remains considerable variation in the operative management of boys with hypospadias in the UK, and it is therefore difficult to identify acceptable standards with regards to reoperation rates. OBJECTIVE: To determine the frequency of reoperations and complications from all centres performing hypospadias surgery in England and to identify variables that influence outcome. METHODS: All children undergoing NHS hypospadias surgery in England between 1999 and 2009 were identified using the Hospital Episode Statistics database...

In 2015, the Society for Maternal Fetal Medicine (SMFM) developed a low risk for cesarean delivery definition based on administrative claims-based diagnosis codes described by the International Classification of Disease, Clinical Modification, 9(th) revision. The SMFM definition is a clinical enrichment of two available measures from the Joint Commission (JC) and the Agency for Healthcare Research and Quality (AHRQ) measures. The SMFM 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...

BACKGROUND: An increasing number of studies are using health administrative databases for tuberculosis (TB) research. However, there are limitations to using such databases for identifying patients with TB. OBJECTIVE: To summarise validated methods for identifying TB in health administrative databases. METHODS: We conducted a systematic literature search in two databases (Ovid Medline and Embase, January 1980-January 2016). We limited the search to diagnostic accuracy studies assessing algorithms derived from drug prescription, International Classification of Diseases (ICD) diagnostic code and/or laboratory data for identifying patients with TB in health administrative databases...

The evaluation of healthcare providers' routine data is an important basis for the analysis, planning and evaluation of measures in public health. The representation of rare diseases in the classifications that are used to record health data is not adequate. Coding rare diseases in a specific way is a challenge all around the world. There is still no general international solution for the routine coding of rare diseases.The double coding of rare diseases with ICD-10 Codes and Orphacodes is a short-term and low-cost alternative solution...

BACKGROUND: The World Health Organization (WHO) aims to reduce tuberculosis (TB) deaths by 95% by 2035; tracking progress requires accurate measurement of TB mortality. International Classification of Diseases (ICD) codes do not differentiate between HIV-associated TB and HIV more generally. Verbal autopsy (VA) is used to estimate cause of death (CoD) patterns but has mostly been validated against a suboptimal gold standard for HIV and TB. This study, conducted among HIV-positive adults, aimed to estimate the accuracy of VA in ascertaining TB and HIV CoD when compared to a reference standard derived from a variety of clinical sources including, in some, minimally-invasive autopsy (MIA)...

Introduction In 2012, the Louisiana (LA) Department of Health and Hospitals revised the LA birth certificate to include medical reasons for births before 39 completed weeks' gestation. We compared the completeness and validity of these data with hospital discharge records. Methods For births occurring 4/1/2012-9/30/2012 at Woman's Hospital of Baton Rouge, we linked maternal delivery and newborn birth data collected through the National Perinatal Information Center with LA birth certificates. Among early term births (37-38 completed weeks' gestation), we quantified the reasons for early delivery listed on the birth certificate and compared them with ICD-9-CM codes from Woman's discharge data...
