Context.—Gynecologic cytopathology is a heavily regulated field, with Clinical Laboratory Improvement Amendments of 1988 mandating the collection of many quality metrics. There is a lack of consensus regarding methods to collect, monitor, and benchmark these data and how these data should be used in a quality assurance program. Furthermore, the introduction of human papilloma virus testing and proficiency testing has provided more data to monitor.Objective.—To determine good laboratory practices in quality assurance of gynecologic cytopathology.Data Sources.—Data were collected through a written survey consisting of 98 questions submitted to 1245 Clinical Laboratory Improvement Amendments–licensed or Department of Defense laboratories. There were 541 usable responses. Additional input was sought through a Web posting of results and questions on the College of American Pathologists Web site. Four senior authors who authored the survey and 28 cytopathologists and cytotechnologists wer...

Context.—There are many long-standing quality monitors for cytopathology laboratories and their cytotechnologists and pathologists. Many of these monitors are based on tradition and empirical good intentions. There is no established standard as to how results of these monitors should be used in a quality assurance program. Objective.—To review practices that are typically part of a general quality program in cytopathology laboratories and to provide statements regarding good laboratory practices that laboratories may find useful in a quality assurance program in their own setting. Data Sources.—An expert working group evaluated results from a national laboratory survey, responses from follow-up questions posted on a Web site, and findings from the literature. The group created statements on good laboratory practices related to general quality practices and quality assurance in gynecologic cytopathology. These were discussed and voted on at a consensus conference. Conclusions.—Labora...

Context.— The College of American Pathologists (CAP) updated the Laboratory Accreditation Program Cytopathology Checklist to assist laboratories in meeting and exceeding the Clinical Laboratory Improvement Amendments standards for gynecologic cytologic-histologic correlation (CHC). Objective.— To survey the current CHC practices. Design.— Data were analyzed from a survey developed by the committee and distributed to participants in the CAP Gynecologic Cytopathology PAP Education Program mailing. Results.— Worldwide, CHC practice is nearly universally adopted, with an overall rate of 87.0% (568 of 653). CHC material was highly accessible. CHC was commonly performed real time/concurrently at the time the corresponding surgical pathology was reviewed. Investigation of CHC discordances varied with North American laboratories usually having a single pathologist review all discrepant histology and cytology slides to determine the reason for discordance, while international laboratories ha...

• Context.-Minimum cellular criteria for satisfactory Papanicolaou tests were established with the Bethesda System in 2001, and unsatisfactory rates are used as a qualityreporting measure. Objective.-To evaluate practices and unsatisfactory rates from laboratories responding to the 2007 College of American Pathologists supplemental questionnaire survey. Design.-In 2007, a supplemental questionnaire was mailed to 1621 laboratories enrolled in the 2006 College of American Pathologists Interlaboratory Comparison Program in Gynecologic Cytology (PAP Education), requesting data from the 2006 calendar year. Unsatisfactory rates, reasons for unsatisfactory specimens, laboratory size, and specimen preparation type were analyzed. Results.-A total of 42% of the laboratories responded to the survey. Most of those laboratories (637 of 674; 94.5%) used the Bethesda System minimum cellularity criteria. Of those laboratories responding, 79% (527 of 667) used the Bethesda System criteria for atrophic or postirradiation specimens. Unsatisfactory rates have increased since 1996. SurePath preparations were associated with the lowest unsatisfactory rate (50th percentile, 0.30; 95th percentile, 1.3), conventional Papanicolaou tests had the highest 95th percentile rates (50th percentile, 1.0; 95th percentile, 5.90), and ThinPrep specimens had the highest median percentile (50th percentile, 1.1; 95th percentile, 3.4). The most-common reason for unsatisfactory Papanicolaou tests was too few squamous cells. Air-drying artifact was the least-common reason for unsatisfactory reporting for liquid-based preparations. Conclusions.-Use of the Bethesda System criteria for unsatisfactory specimens is widespread. Unsatisfactory rates have increased since 1996; however, the median rates are 1.1% or less for all preparations. Results from the College of American Pathologists PAP Education supplemental questionnaire continue to provide valuable benchmarking data for cytologic quality-improvement programs in laboratories.

Although objective measures of cytotechnologist (CT) and cytopathologist (CP) performance exist, challenges remain. Two assumptions deserve examination: CPs' interpretations are correct, and CTs and CPs render interpretations independently of each other. This study presents a CT-CP interpretation comparison and provides insight into these assumptions. Every gynecologic cytology specimen examined by both a CT and a CP from December 2004 to March 2015 was extracted from the laboratory information system; glandular interpretations were excluded. Excel and SAS were used for CT-CP pair analysis. CT-CP pairs with fewer than 32 specimens (the lowest quartile) were excluded. For the remaining CT-CP pairs, 30 specimens or 10% of the specimens (whichever was higher) were randomly selected for comparison by a weighted κ statistic. κ values greater than 0.6 represented good agreement within CT-CP pairs. This study evaluated 7116 of 53,241 gynecologic cytology specimens (13.4%) that received...

Context.-Implementation of proficiency testing for gynecologic cytology was delayed 20 years because of challenges addressing the subjective nature of cytologic interpretation and replicating normal working conditions. Concern remains regarding test scoring, slide validation, test environment, and other issues. How these test results are, or should be, used in quality management has never been explored. Objective.-To provide information on good laboratory practices for gynecologic cytology proficiency testing based on findings from the College of American Pathologists' survey-based project funded by the Centers for Disease Control and Prevention. Data Sources.-An expert working group evaluated results from a Web-based, national laboratory survey plus responses from follow-up questions and findings from the literature. The group created statements on good laboratory practices pertinent to proficiency testing and its role in quality management, which were discussed and voted on at a consensus conference.

Introduction Rapid on-site evaluation (ROSE) is a service provided by cytologists that helps ensure specimen adequacy and appropriate triage for ancillary testing. However, data on the current usage patterns across different practice settings have been lacking. Materials and methods To obtain an accurate and timely assessment of the current state of practice of ROSE, a 14-question online survey was constructed by the Clinical Practice Committee of the American Society for Cytopathology. The survey was available to the membership of the American Society for Cytopathology for a 3-week period in early 2019. Results A total of 541 responses were received, including from 255 cytopathologists/pathologists, 261 cytotechnologists, 19 cytology resident/fellow trainees, and 6 others. ROSE was offered as a clinical service by 95.4% of the respondents, with telecytology for ROSE used in 21.9% of the practices. Endobronchial ultrasound-guided transbronchial needle aspiration was the procedure most frequently reported to use ROSE (mean, 59.1%; median, 70%). Cytotechnologists were involved in ROSE in most practices. The number of daily ROSE procedures correlated with the annual nongynecologic cytology volumes. Approximately 70% of ROSE procedures were reported to require >30 minutes, on average, for the cytologist. Conclusions The results from our survey of cytologists have shown that the reported practice patterns for the usage of ROSE vary considerably. The presented data can help inform future guideline recommendations and the implementation of ROSE in different clinical settings.

Context.-Cytopathology experts, interested stakeholders, and representatives from the College of American Pathologists, the Centers for Disease Control and Prevention, the American Society of Cytopathology, the Papanicolaou Society of Cytopathology, the American Society for Clinical Pathology, and the American Society of Cytotechnology convened the Gynecologic Cytopathology Quality Consensus Conference to present preliminary consensus statements developed by working groups, including the Cytologic-Histologic Correlations Working Group 4, using results from surveys and literature review. Conference participants voted on statements, suggested changes where consensus was not achieved, and voted on proposed changes. Objectives.-To document existing practices in gynecologic cytologic-histologic correlation, to develop consensus statements on appropriate practices, to explore standardization, and to suggest improvement in these practices. Data Sources.-The material is based on survey results from 546 US laboratories, review of the literature from 1988 to 2011, and the College of American Pathologists Web site for consensus comments and additional survey questions. Conclusions.-Cytologic-histologic correlations can be performed retrospectively, during initial case review, or both. At minimum, all available slides should be reviewed for a high-grade squamous intraepithelial lesion Papanicolaou test with negative biopsies. The preferred monitor for correlations is the positive predictive value of a Papanicolaou test. Laboratories should design cytologic-histologic correlation programs to explore existing or perceived quality deficiencies.

Context.-Liquid-based preparations (LBPs) and human papillomavirus testing have led to changes in cervical cytology practices. The College of American Pathologists attempts to track practice patterns using a supplemental questionnaire, which allows laboratories to report diagnostic practices. Objective.-To analyze the 2006 reporting practices and to compare the results with the 2003 survey data. Design.-Questionnaire was mailed to 1621 laboratories. Participants included laboratories enrolled in the 2006 College of American Pathologists Gynecologic Proficiency Testing Program or the educational Interlaboratory Comparison Program in Gynecologic Cytology. Results.-Of the 679 responding laboratories (response rate, 42%), most (97.8%; n = 664) had implemented the Bethesda 2001 terminology. The median rate for all preparations with low-grade squamous intraepithelial lesions was 2.5% (2.9% for LBPs) compared with a 2003 median rate of 2.1%; the increase was confined to LBPs. Rates for high-grade squamous intraepithelial lesions (median, 0.5%) and atypical squamous cells have changed little. High-grade squamous intraepithelial lesions and unsatisfactory rates varied at statistically significant levels between types of LBPs. Most atypical squamous cell cases were subclassified as undetermined significance (median, 4.3%). The median ratio of atypical squamous cells to squamous intraepithelial lesions and carcinomas for all specimen types combined was 1.5, similar to the 2003 median ratio of 1.4. The median rates for findings of squamous cell abnormalities for 2006 were significantly higher for LBPs than for conventional smears. Conclusions.-Most responding laboratories have implemented the Bethesda 2001 terminology. There is an increase in LBP low-grade squamous intraepithelial lesion rates when compared with 2003 data. Liquid-based preparations have higher median squamous intraepithelial lesion and atypical squamous cell rates.
