Quality Of Surgery

AbstractBackgroundThe aim of our study was to evaluate the quality of surgery of Slovenian breast cancer screening program (DORA) using the requested EU standards. Furthermore, we investigated whether regular quality control over the 3-year period improved the quality of surgical management.Patients and methodsPatients who required surgical management within DORA between January 1st, 2016 and December 31st, 2018 were included in the retrospective study. Quality indicators (QIs) were adjusted mainly according to European Society of Breast Cancer Specialists (EUSOMA) and European Breast Cancer Network (EBCN) recommendations. Five QIs for therapeutic and two for diagnostic surgeries were selected. Additionally, variability in achieving the requested QIs among surgeons was analysed.ResultsBetween 2016 and 2018, 14 surgeons performed 1421 breast procedures in 1398 women. There were 1197 therapeutical (for proven breast cancer) and 224 diagnostic surgical interventions respectively. Overall, the minimal standard was met in two QIs for therapeutic and none for diagnostic procedures. A statistically significant improvement in three QIs for therapeutic and in one QI for diagnostic procedures was observed however, indicating that regular quality control improves the quality of surgery. A high variability in achieving the requested QIs was observed among surgeons, which remained high throughout the study period.ConclusionsAdherence to all selected surgical QIs in patients from screening program is difficult to achieve, especially to those specifically defined for screen-detected lesions. Regular quality control may improve results over time. Reducing the number of surgeons dedicated to breast pathology may reduce variability of management inside the institution.

Background: To evaluate the quality of an organized mammography screening program based on the perception of screened women, we developed and validated the French-language Mammography Satisfaction Instrument (MSI). The study objective was to confirm the validity and reliability of the MSI. Methods: A confirmatory study was conducted among 529 women who had had a recent screening mammography under the Quebec Breast Cancer Screening Program (PQDCS). Eligible women from the Quebec City region completed the online MSI between January 14 and May 23, 2016. The MSI originally included 14 items evaluating 4 factors: satisfaction with (1) the technician’s skills; (2) the physical environment; (3) the staff’s communication skills; and (4) the information provided under the program. A fifth factor with 2 items, evaluating mammography accessibility, was added. A confirmatory factor analysis (CFA) was done and goodness of fit indices were generated (SRMR, CFI, RMSEA with its 90% CI). Item reliability and composite reliability were estimated. Variance extract estimates (VEEs) were generated to assess the amount of variance explained by the factors. Multivariate logistic regressions were done to test the sensitivity of each scale to identify subgroups of unsatisfied women. Odds ratios (OR) and their 95% CI were estimated. Results: Most women (62.0%) were aged 55–64, and 32.9% had university level education. The CFA demonstrated that the 5 factors fitted the data well (SRMR=0.044; CFI=0.969; RMSEA=0.055 with its 90% CI: 0.047–0.063). Item reliabilities (≥0.55) and composite reliabilities (≥0.87) were high. All VEEs were also high (≥0.70). Pain during compression, anxiety before the mammography, perception of not having an excellent health, and the radiologic centers were the factors the most consistently and significantly associated with the 5 scales of satisfaction. In addition, women with university level education were less satisfied with the staff’s communication skills (OR=0.64; 95% CI: 0.43–0.97) and those having had less than 10 lifetime mammograms were less satisfied with the physical environment (OR=0.52; 95% CI: 0.33–0.83) and the accessibility (OR=0.53; 95% CI: 0.31–0.92). Conclusions: This confirmatory study showed the good reliability and validity of the construct of the 16-item MSI with 5 factors. The MSI is useful to detect unsatisfied women and to improve the quality of organized breast cancer screening programs.

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.

Abstract Background Breast cancer remains one of the leading causes of death in women over the age of 40 years. Breast cancer screening is used to identify women with asymptomatic cancer with the goal of enabling women to undergo less invasive treatments that lead to better outcomes, ideally at earlier stages and before the cancer progresses. Mammography is the best-studied breast cancer screening modality and the only recommended imaging tool for screening the general population of women. Objective to correlate the relation between ACR density of breast and breast cancer in screening program. Patients and Methods Our study included 40 women of breast cancer were depicted radiologically and histo-pathologically diagnosed after outreaching for screening by Digital Mammography by the Egyptian National Breast Cancer Screening Program in Ain Shams University Hospitals at period from January 2018 to October 2019.Their data were collected from the medical records of the program. Their age ranged between 40 and 65 years. Results According to the BI-RADS 5th edition 2013, cases were classified into four classes as follows: 6 were ACR-A (15.0%), 21 were ACR-B (52.5%), 12 were ACR-C (30.0%) and 1 were ACR-D (2.5%), So according to our study results dense breast shouldn’t be considered as a risk factor for breast cancer as we observed that the percentage of breast cancer in our study increases the most with average breast density ACR class B then increases with ACR class C and A respectively. Conclusion dense breast is not a risk factor for breast cancer, so further researches are needed to study the relationship between breast density and breast cancer in Egyptian population, to elucidate the role of breast density estimation in prediction of breast cancer considering the genotypical and phenotypical differences of the Egyptian population.
