Abstract

Background

The retention rate or the percentage of women who return to screening within 30 months of a previous screening is an important measure of screening success and the acceptability of the screening program to women. The objective of this study was to investigate variables associated with the retention of women 50 to 68 years of age who were screened by the Manitoba Breast Screening Program (MBSP) during 2002 and 2003.

Methods

All women screened by the MBSP in 2002 and 2003 who were eligible for re-screening in 2 years were included in the study. Data were extracted from the MBSP database which contains demographic, screening, diagnostic follow-up, and diagnosis information for all women screened by the program. Contingency tables, ?2 tests, and logistic regression were used to investigate variables that were associated with retention.

Results

Retention was related to screen type (first or return), screen result (normal or abnormal), family history of breast cancer (risk or no risk), education (less than grade 9 or some high school or more), and ethnicity (Asian, First Nations, other). Retention was not related to residence (rural or urban).

Conclusions

Overall screening retention at the MBSP was 80% which meets national standards. However, additional efforts may be required to improve the retention rate of Asian and First Nations women as well as women who had an abnormal screening result or less than a grade 9 level of education.

Résumé

Contexte

Le taux de persévérance (le pourcentage des femmes qui se soumettent de nouveau à un examen de dépistage dans les 30 mois qui suivent un examen antérieur) est un indicateur important du succès d’un programme de dépistage et de son acceptabilité auprès des femmes. Cette étude avait pour objectif d’examiner les variables associées à la persévérance chez les femmes de 50 à 68 ans ayant subi un examen de dépistage du Programme manitobain de dépistage du cancer du sein (PMDCS) en 2002 et 2003.

Méthode

L’étude a tenu compte de toutes les femmes qui ont subi un examen de dépistage du PMDCS en 2002 et 2003 et qui étaient admissibles à un redépistage après 2 ans. Les données ont été extraites de la base du PMDCS, qui contient des données démographiques, de dépistage, de suivi diagnostique et de diagnostic sur toutes les femmes ayant subi un examen de dépistage dans le cadre du programme. Pour examiner les variables associées à la persévérance, on a utilisé les tableaux de contingence, le test du khi-carré et la régression logistique.

Résultats

La persévérance a été associée au type d’examen de dépistage (premier ou subséquent), au résultat de l’examen (normal ou anormal), aux antécédents familiaux de cancer du sein (à risque ou non), à la scolarité (8e année ou moins, certaines études secondaires, études supérieures) ainsi qu’à l’origine ethnique (asiatique, Premières nations, autre). La persévérance n’a pas été associée au lieu de résidence (milieu rural ou urbain).

Conclusions

Dans l’ensemble, le taux de persévérance en ce qui concerne les examens de dépistage du PMDCS était de 80%, ce qui satisfait aux normes nationales. Toutefois, il faudrait peut-être déployer davantage d’efforts pour améliorer le taux de persévérance chez les femmes asiatiques et des Premières nations ainsi que chez les femmes dont l’examen de dépistage s’est traduit par un résultat anormal ou qui ont moins de 9 ans de scolarité.
