“…A few studies [15][16][17][18][19] have examined the association of radiologists' interpretation volume with their performance. Four of them [15][16][17][18] were conducted as experiments; since performance in a test environment appears to be unrelated to performance in actual practice, 20,21 the relevance of the results of these studies to our purposes is questionable.…”

“…Our study support findings from five studies showing volume to be of importance. [18][19][20][21][22] For example, Theberge et al 21 showed that radiologist who read more than 2,000 mammograms per year had higher sensitivity while maintaining low specificity. Our results are in contrast with those of previous studies finding that increased volume may not necessarily increase performance.…”

“…Radiologist training in general has been associated with increased performance. [12][13][14][15][16][17] Data on the relationship between volume read per radiologist and performance are, however, conflicting, 13,[18][19][20][21][22] whereas associations have been found between some other indicators of radiologists' experience and performance. [23][24][25] However, most studies focused on mammography screening, and no large community based study has evaluated the association between organisational factors and performance of diagnostic mammography.…”

Clinical mammography is the key tool for breast cancer diagnosis, but little is known about the impact of the organisational set-up on the performance. We evaluated whether organisatorial factors influence the performance of clinical mammography. Clinical mammography data from all clinics in Denmark in the year 2000 were collected and linked to cancer outcome. Use of the National Institute of Radiation Hygiene register for identification of radiology clinics ensured comprehensive nationwide registration. We used the final mammographic assessment at the end of the imaging work-up to determine sensitivity, specificity and accuracy, the latter using a receiver-operating characteristics (ROC) analysis. In 96,534 clinical mammography examinations, sensitivity was 75% and specificity 99%. The presence of at least one high volumereading radiologist in the clinic increased accuracy (AUC 5 0.91 for <1,000 examinations/year and 0.92 for >2,000 examinations/ year, p 5 0.017). The examination volume per clinic showed no clear effect on performance, as accuracy was significantly higher in clinics with a medium number of examinations (AUC 5 0.93 for 2,000-4,000 examinations/year and 0.90 for >6,000 examinations/year, p 5 0.003). Accuracy was significantly lower in regions with high annual utilisation rate of clinical mammography, which means the proportion of examined women in a region (AUC 5 0.90 for 3.0-5.0% annual utilisation rate and AUC 5 0.93 for 2.0-2.5% annual utilisation rate, and p 5 0.001), indicating that clinical mammography worked best in patient populations of purely symptomatic women. Our data indicate that to increase the accuracy of clinical mammography at the community level, the presence of an experienced radiologist should be prioritised ahead of raising the clinic size. ' 2006 Wiley-Liss, Inc.Key words: mammography; breast cancer; organization; sensitivity; specificity; accuracy Diagnostic mammography is the most commonly used tool for diagnosing breast cancers in women with signs or symptoms of this disease. It is most often undertaken in combination with a clinical examination and supplemented with ultrasound or other imaging techniques. 1 In contrast to mammography screening, performance of diagnostic mammography has been examined only in a few studies. In addition, the majority of these studies are singleclinic studies covering small populations, 1-5 and only two studies have evaluated the performance of diagnostic mammography at the community level. 6,7 Performance of mammography is known to be influenced by factors related to woman characteristics, such as age, breast density, history of previous breast lesions and presence of symptoms. 6,[8][9][10][11] However, performance of mammography may also be related to the organisational setup, such as the type of clinic, the number of examinations undertaken and the experience of the radiologists. Radiologist training in general has been associated with increased performance. 12-17 Data on the relationship between volume read per radiologist and performan...
