False Positive Result

AbstractWe conducted a cross-sectional study to assess the likelihood of returning for routine breast cancer screening among women who have experienced a false-positive result (FPR) and to describe the possible individual and organizational factors that could influence subsequent attendance to the screening program. Several information were collected on demographic and clinical characteristics data. Electronic data from 2014 to 2016 related to breast screening program of the Local Health Authority (LHA) of Bologna (Italy) of women between 45 and 74 years old were reviewed. A total of 4847 women experienced an FPR during mammographic screening and were recalled to subsequent round; 80.2% adhered to the screening. Mean age was 54.2 ± 8.4 years old. Women resulted to be less likely to adhere to screening if they were not-Italian (p = 0.001), if they lived in the Bologna district (p < 0.001), if they had to wait more than 5 days from II level test to end of diagnostic procedures (p = 0.001), if the diagnostic tests were performed in a hospital with the less volume of activity and higher recall rate (RR) (p < 0.001) and if they had no previous participation to screening tests (p < 0.001). Our results are consistent with previous studies, and encourages the implementation and innovation of the organizational characteristics for breast cancer screening. The success of screening programs requires an efficient indicators monitoring strategy to develop and evaluate continuous improvement processes.

Estimation Of Variance

Purpose The study sought to determine if mammography quality is associated with the false positive (FP) rate in the Quebec breast cancer screening program in 2004 and 2005. Methods Mammography quality of a random sample of screen-film mammograms was evaluated by an expert radiologist following the criteria of the Canadian Association of Radiologists. For each screening examination, scores ranging from 1 (poor quality) to 5 (excellent quality) were attributed for positioning, compression, contrast, exposure level, sharpness, and artifacts. A final overall quality score (lower or higher) was also given. Poisson regression models with robust estimation of variance and adjusted for potential confounding factors were used to assess associations of mammography quality with the FP rate. Results Among 1,209 women without cancer, there were 104 (8.6%) FPs. Lower overall mammography quality is associated with an increase in the FP rate (risk ratio [RR], 1.4; 95% confidence interval [CI], 1.0-2.1; P = .07) but this increase was not statistically significant. Artifacts were associated with an increase in the FP rate (RR, 2.1; 95% CI, 1.3-3.3; P = .01) whereas lower quality of exposure level was related to a reduction of the FP rate (RR, 0.4; 95% CI, 0.1-1.0; P = .01). Lower quality scores for all other quality attributes were related to a nonstatistically significant increase in the FP rate of 10%-30%. Conclusions Artifacts can have a substantial effect on the FP rate. The effect of overall mammography quality on the FP rate may also be substantial and needs to be clarified.

Célkitűzés: Az országos kiterjedésű, szervezett emlőszűrési program 2002 januárjában indult el Magyarországon a 45–65 év közötti nők számára 2 éves szűrési intervallummal. A dolgozat célja a szervezett emlőszűrési program részvételi mutatóinak meghatározása, beleértve a szűrési és diagnosztikus célú képalkotó emlőfelvételek gyakoriságának elemzését. Adatok és módszerek: Az elemzésben szereplő adatok az Országos Egészségbiztosítási Pénztár finanszírozási adatbázisából származnak, és a 2000–2005 közötti 6 évet ölelik fel. A 45–65 éves nők körében meghatározták azok arányát, akik a szervezett szűrést megelőző két évben (2000–2001), illetve a program első két ciklusában (2002–2003, 2004–2005) akár szűrési, akár diagnosztikai célú képalkotó emlővizsgálaton vettek részt. Eredmények: A szűrési célú képalkotó emlőfelvételen részt vettek aránya (átszűrtség) a 2000–2001-es 7,4%-ról a 2002–2003-as, illetve 2004–2005-ös szervezett emlőszűrési ciklusban 34,0, illetve 29,5%-ra emelkedett. A diagnosztikus célú képalkotó emlőfelvételen részt vettek aránya (átvizsgáltság) pedig ugyanezen időszakokban 19,8%-ról 22,1 (2002–2003), illetve 23,2%-ra (2004–2005) emelkedett. Az országos lefedettség (átszűrtség + átvizsgáltság) ennek megfelelően a szervezett szűrés hatására 26,2%-ról (2000–2001) 53,5%-ra (2002–2003), illetve 50,8%-ra (2004–2005) nőtt a vizsgált kétéves ciklusban a 45–65 év közötti nők esetében. Következtetés: A magyar emlőszűrési program kezdeti részvételi arányai 2004–2005-ben kissé csökkentek; az emlőrák miatti halálozás érdemi csökkentéséhez ennek emelése szükséges.
