  • Title: Exploring avenues for best use of cytotechnologists in non-gynaecological cytology: Double screening or independent sign-out.
    Author: Fischer G, Haddad M, Cormier K.
    Journal: Cytopathology; 2018 Feb; 29(1):90-96. PubMed ID: 28914465.
    Abstract:
    OBJECTIVE: Cytotechnologist (CT) screening workload has been decreasing due to the falling number of Papanicolaou tests. This continuing trend has prompted exploration of ways to best employ the CT skillset. One potential way of more effective use is by having two CTs double screen non-gynaecological (NGC) cases to assess whether this improves screening quality and concordance with pathologists. Another is evaluating the CT's performance on low-complexity negative NGC cases for a potential independent CT sign-out without pathologist review. METHODS: In total, 1119 NGC cases were reviewed; 577 screened by two CTs and 542 screened by one CT. All cases were signed out by a pathologist and all CT interpretations were compared to the pathologist final diagnoses. The disagreements were classified based on degree of discrepancy. The extra workload by adding the second screener was assessed. RESULTS: The agreement rate between the CT's screening interpretation and pathologist's interpretation did not improve by adding a second CT compared to a single screener (91.5% vs 92.9%, respectively). CT to pathologist concordance was very high on low complexity NGC cases (voided urine, fluid, sputum) whether screened and interpreted as negative by one CT (97.3%) or two CTs (99.3%). CONCLUSION: Double screening of NGC cases by two cytotechnologists prior to pathologist sign-out does not improve screening quality and is not cost-effective. The high concordance between the CTs and pathologists in this limited group of low complexity negative cases suggests that such cases could be signed out independently by cytotechnologists.
