Cervical cytology screening and government policy.

OBJECTIVE--To assess the coverage of cervical cytology screening in one general practice surgery according to the criteria in the new Scottish general practitioner contract and to explore the difficulties of defining performance in such screening. DESIGN--Review of annual analysis of uptake of screening during 1984-8. SETTING--Suburban general practice surgery in Glasgow serving 3000 patients. PATIENTS--All women aged 35-64 registered in 1984 increasing in 1988 to all women aged 20-64. MAIN OUTCOME MEASURE--Assessment of uptake of smear tests and reasons for smear not being taken and of the effect of these outcomes on the new general practitioner contract. RESULTS--The numbers and percentages of women having a smear test in the previous five and three years were recorded, and the reasons why a smear was not taken were defined in the remainder (hysterectomy, test not offered, risk not known, test declined, patient moved away, and patient unaccounted for). In 1988, 85% (608/719) of the women aged 30-64 and 80% (693/870) of those aged 20-64 had had a smear test in the previous five years. An appropriate or irreducible reason for the lack of a smear test was defined in all the others. CONCLUSIONS--The population studied contained a substantial number of women in whom cervical smear was unnecessary, inappropriate, or refused. These factors and the likely demographic variation in the uptake of smear tests have important implications for the setting and achieving of the government''s targets for cervical cytology screening.     

Cervical cytology screening: experience of a general hospital.

At Henderson General Hospital, Hamilton, a program was introduced whereby cervical smears were taken routinely for cytologic study from all women admitted aged 17 years or older. The procedure was performed by a specially trained nurse. In a 5-year period 53% of eligible patients were screened. Of these, 32% had not had a cervical smear taken before. In 7681 smears nine instances of invasive disease were discovered: three of the cervix, three of the endometrium and three metastatic. There were 20 cases of carcinoma in situ and 2 of severe dysplasia. Evidence of infection was present in a high percentage of the smears. Hospital admission affords an excellent opportunity of applying this valuable screening procedure.     

Liquid-based cytology improves productivity in cervical cytology screening.

Objectives: The ThinPrep test was introduced into our institution on a phased basis over 3 years between January 2002 and December 2004. This study set out to assess its effect on productivity (as measured by output of cases per medical scientist per day) during the changeover period. Numbers of high and low-grade lesions and of unsatisfactory slides were also monitored. Methods: The percentage conversion from conventional preparation to liquid-based cytology (LBC) and output of cases per medical scientist per day were calculated from our database at 6-month intervals. The average backlog, average number of cases received per month and percentage of unsatisfactory and abnormal cases were calculated similarly. Results: Over the study period 92 084 cases were received. The percentage of cases using ThinPrep increased: from 9% in January 2002 to 73% in December 2004. During the study there was an increase in output from 17.0 to 22.3 cases per medical scientist per day, representing a 31% improvement at 73% conversion. Numbers of unsatisfactory cases decreased substantially and the numbers of low and high-grade diagnoses were relatively constant. Conclusions: The change to ThinPrep has improved productivity and decreased the number of unsatisfactory cases. There was no adverse effect on quality during the changeover.     

Cervical cytology quality assurance in Washington State.

The objectives of this study were to establish a profile of cervical cytology laboratories in Washington State, identify quality assurance problems amenable to correction through education or legislation, and describe differences between large and small cytology laboratories. All 43 Washington laboratories that perform cervical cytology were surveyed by mail during 1989. Completed surveys were returned by 37 (86%) of the laboratories. Nearly half (43%) of the respondents reported processing less than 10,000 Papanicolaou smears annually. Only one-third (35%) of the respondents reported participating in relevant proficiency programs. A proportion of smaller cytology laboratories were compensating their cytotechnologists on the basis of the number of slides read and allowing Papanicolaou smears to be read outside the confines of the laboratory. The results of this study suggest that cytotechnologists in some larger Washington laboratories have been exceeding work load limits recommended by professional associations. Recent legislation includes regulations that address cervical cytology quality assurance. However, continued efforts will need to be made to encourage voluntary adoption of quality control measures not addressed by this legislation.     

Anal screening cytology

This issue of CytoJournal contains an article on screening for anal intraepithelial neoplasia in high-risk male patients. This accompanying Editorial focuses on current understanding of this relatively new disease entity, with insights as to the potential role of screening cytopathology in the epidemiology, pathophysiology and clinical management of this HIV and HPV related anal lesion, which predominates in male patients living long-term with AIDS. Mention is made of techniques of obtaining samples, methods of preparation, and morphologic classification. Issues of anoscopic confirmation, as well as topical and surgical management are emphasized. The similarity of initial experiences in anal screening to problems encountered early in cervical cancer screening programs several decades ago, are highlighted.
