Effects of the Bethesda System on the rate of unsatisfactory Pap smears in spontaneous cervical screening.
AIMS: In 1990, The Bethesda System (TBS) was introduced into spontaneous cervical screening practice in Ravenna, Italy. Negative/benign reports with the recommendation for early repeat smears (RERS) due to some limitation in sample adequacy were considered no longer acceptable. A monitoring program for the rate of unsatisfactory smears (UNS) was implemented. The aim of the present study was to evaluate the effects of such changes in the screening procedure. METHODS: The frequency of UNS in 1990 was compared with that of UNS+RERS in 1988 (assumed as a baseline year) by the calculation of the standardized rate ratio with the 95% confidence interval (CI). The trend in the standardized rate of UNS from 1990 to 1994 was evaluated by the calculation of the average annual variation with the 95% CI. RESULTS: The immediate effect of TBS (1990; 1988 comparison) was a significant increase in the rate of UNS attributable to scant cellularity, poor fixation and thick areas (rate ratio, 2.35; 95% CI, 2.18 to 2.53) and to the absence of endocervical component (1.45; 95% CI, 1.30 to 1.60). The rate of UNS attributable to the presence of cytolysis, inflammation, blood and foreign material decreased by about 6 times (0.16; 95% CI, 0.13 to 0.19). The midterm effect of TBS (trend from 1990 to 1994) was a decrease in the total rate of UNS by an average of 2.3% per year. The downward trend was significant for smears showing scant cellularity, poor fixation and thick areas (-1.5% per year) and the absence of endocervical component (-0.7% per year). UNS attributable to the presence of cytolysis, inflammation, blood and foreign material stabilized. CONCLUSIONS: TBS led to a substantial change in the type of information provided by the cytology report (immediate effect). The monitoring program according to TBS led to a reduction in UNS attributable to sample taker (midterm effect).

A first survey of organized cervical cancer screening programs in Italy. GISCi working group on organization and evaluation. Gruppo Italiano Screening Citologico.
In Italy, where no national screening program for cervical cancer exists, organized programs have developed on a local basis. We performed the first survey of existing organized programs by mailing a standard questionnaire to a large network of possibly involved services. For the present survey, a program was defined as organized if personal invitations were sent. We identified 29 already active organized programs and 4 others in a starting phase. The target population of active programs included 2,074,820 women in the age range 25-64 years, corresponding to 13.5% of the Italian female population of the same age. The situation is rapidly evolving since many regional programs are being implemented. Most programs followed Italian and European recommendations as regards the age limits, interval between screening rounds, presence of a fail-safe system for women referred for colposcopy, presence of protocols for diagnostic workup and treatment, and presence of referral centers for such phases. However, many programs did not meet national guidelines as regards the size of laboratories interpreting smears, which were frequently small. Second-level referral centers also frequently had a very small activity. The average (weighted for size of the invited population) compliance to invitation and coverage (proportion of women with at least one test in the last 3 years) was 32.6% and 66.0%, respectively, therefore needing to be improved. Compliance to colposcopy (weighted for number of referred women) was 81.4%. We found a very high variability in the proportion of women referred for colposcopy that could only be partly explained by different referral protocols and could depend on different criteria of smear interpretation: the average (weighted for number of tested women) was 2.01%. A need for improvement in the process of evaluation and for homogenization of criteria of cytology interpretation was identified: work in this regard is on-going.
