TLDR
To summarise validated methods for identifying TB in health administrative databases, a systematic literature search in two databases found diagnostic accuracy measures of algorithms using out-patient, in-patient and/or laboratory data vary widely across studies.Abstract:
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. Results The search identified 2413 unique citations. Of the 40 full-text articles reviewed, we included 14 in our review. Algorithms and diagnostic accuracy outcomes to identify TB varied widely across studies, with positive predictive value ranging from 1.3% to 100% and sensitivity ranging from 20% to 100%. Conclusions Diagnostic accuracy measures of algorithms using out-patient, in-patient and/or laboratory data to identify patients with TB in health administrative databases vary widely across studies. Use solely of ICD diagnostic codes to identify TB, particularly when using out-patient records, is likely to lead to incorrect estimates of case numbers, given the current limitations of ICD systems in coding TB.read more

Administrative data identify sickle cell disease: A critical review of approaches in U.S. health services research.
TL;DR: Validation studies conducted using clinical records and newborn screening for confirmation of SCD case status have found that algorithms that require three or more nonpharmacy claims or one inpatient claim plus two or more outpatient claims with SCD codes show acceptable accuracy in children and adolescents.

TL;DR: In this paper, the authors estimate the frequency and duration of diagnostic delays among patients with active pulmonary tuberculosis and determine the risk factors for experiencing a diagnostic delay, using a simulation-based approach to estimate the number of patients experiencing a delay, number of missed opportunities per patient and the duration of delays.

Identification of congenital CMV cases in administrative databases and implications for monitoring prevalence, healthcare utilization, and costs.
TL;DR: In this article, a review of the use of diagnosis codes to identify congenital cytomegalovirus infection or disease in healthcare administrative databases is presented. Understanding the limitations of the diagnosis codes is discussed.

TL;DR: Health care administrative databases are increasingly used for health studies and public health surveillance, and cases of individuals with obesity are selected using case‐identification methods, which are fragmentary and particularly challenging for obesity case identification.

Which ICD-9-CM codes should be used for bronchiolitis research?
Paul Walsh,Stephen J. Rothenberg +1 more
TL;DR: Users of Medic-Aid administrative data should generally favor broad rather than narrow definitions of bronchiolitis and should perform sensitivity analysis comparing broad and narrow definitions.
