[Computerized monitoring for integrated cervical screening. Rationale, methods and indicators of participation].

This paper presents a computerised system for the monitoring of integrated cervical screening, i.e. the integration of spontaneous Pap smear practice into organised screening. The general characteristics of the system are described, including background and rationale (integrated cervical screening in European countries, impact of integration on monitoring, decentralised organization of screening and levels of monitoring), general methods (definitions, sections, software description, and setting of application), and indicators of participation (distribution by time interval since previous Pap smear, distribution by screening sector--organised screening centres vs public and private clinical settings--, distribution by time interval between the last two Pap smears, and movement of women between the two screening sectors). Also, the paper reports the results of the application of these indicators in the general database of the Pathology Department of Imola Health District in northern Italy.

[Computerised monitoring of integrated cervical screening. Indicators of diagnostic performance].

In a previous issue of this journal, we presented the background, rationale, general methods, and indicators of participation of a computerised system for the monitoring of integrated cervical screening, i.e. the integration of spontaneous Pap smear practice into organised screening. We also reported the results of the application of those indicators in the general database of the Pathology Department of Imola Health District in northern Italy. In the current paper, we present the rationale and definitions of indicators of diagnostic performance (total Pap smears and rate of unsatisfactory Pap smears, distribution by cytology class reported, rate of patients without timely follow-up, detection rate, positive predictive value, distribution of cytology classes reported by histology diagnosis, and distribution of cases of CIN and carcinoma registered by detection modality) as well as the results of their application in the same database as above.

Cervical screening behavior of women with atypical squamous cells of undetermined significance (ASCUS).

Expectant follow-up based on early repeat Papanicolaou (Pap) smear(s) is the most commonly recommended management of patients with atypical squamous cells of undetermined significance (ASCUS). In a cervical cytology laboratory in northern Italy, a retrospective study of 1,087 ASCUS patients aged 25-64 was conducted. The primary aim was to assess the actual probability of early repeat Pap smear and associated factors. Univariate comparisons were based on the actuarial method. Multivariate associations were evaluated by Cox regression analysis. The cumulative probability of early repeat Pap smear was 0.11 at 6 mo, 0.29 at 12 mo, and 0.41 at 24 mo, with a multivariate association with screening sector (relative hazard, 3.0 for public offices and 2.8 for private offices vs. organized screening) and previous Pap smear history. Laboratory recommendation, patient age, place of birth, place of residence, marital status, and occupation exerted no independent effect. In conclusion, the probability of early repeat Pap smear was poor and independent of demographic and social factors. The frequency of follow-up failures emerged as a major problem with ASCUS management.
