Simply put, CH correlation is the process by which cytologic and histologic interpretations are compared, generally from the same anatomic site, to determine whether they are concordant or discordant. 2-9 In most scenarios, a discordant diagnosis meets the Institute of Medicine (IOM) definition of medical error.Jul 5, 2011.
Background: Cytology-histology correlation is a method of detection of an error in the diagnostic field.
The root cause analysis is done for the discordant cases for quality improvement of the laboratory reports.Apr 29, 2019.
Cytology-histology correlation (CHC) is a method of detection of an error in the diagnostic field where the cytology interpretations are compared with the histopathology interpretation of the specimens from the same site.Apr 29, 2019.
Cytology generally involves looking at a single cell type.
Histology is the exam of an entire block of tissue..
Electronic laboratory information systems vary in their ability to track cytologic and histologic correlation pairs. 26, 30, 31 Vrbin et al conducted a survey of 162 American laboratories on current CH correlation practices 26 to obtain evidence regarding the existing level of variability in correlation methods.
First, the definition used for a discrepant cytologic and histologic diagnosis markedly affected the discrepancy frequency.
In determining whether a diagnosis is discrepant, cytologic and histologic diagnoses must be compared, and these diagnoses are categorized using different scales.
Diagnostics (Basel). 2022 Jul; 12 (7):
The process of cytologic-histologic correlation is highly valuable to the fields of both cytopathology and surgical pathology, because correlation provides a wealth of data that may be used to improve diagnostic testing and screening processes.
