This paper explores barriers to the use of standard screening and breast cancer treatment that result in systematic differences in health outcomes. We review available data on individual, socioeconomic, and health system determinants of access to standard breast cancer care, including screening, diagnostic, and treatment services. Based on this review, we discuss the combination of factors which result in underservice. We argue that a broad framework which considers health system and social class as well as individual factors is useful for analyzing how structures of health care delivery tend to provide less than standard care to women who are older, have less income, or are less educated, black, or Hispanic. Data collection efforts which do not include structural and socioeconomic variables may result in an incomplete or misleading understanding of the determinants of underservice. These factors also need to be considered in the design and evaluation of public health policies and interventions meant to ameliorate the effects of underservice.

Breast cancer screening enables early detection of breast cancer which leads to a reduction in mortality.1,2 The Quebec breast cancer screening program began in 1998 and offers women aged 50-69 a biennial screening mammography. 3 Since 2002, three mammography mobile units were progressively added to the program. The program relies on two motorized units and a portable unit transported by plane or boat that extends screening services to regions not accessible by land. In the present study, we use the term "mobile units" to refer to both (motorized and portable) types of mammography units. The purpose of these units is to provide services to regions not covered by fixed centres. In addition, they can provide temporary relief to fixed centres that have insufficient resources to ensure timely breast screening.Mobile units have been added to screening programs in various countries to increase geographical accessibility to breast cancer screening. 4 Studies have shown that mobile units are effective at improving the participation rate, 5-7 that mobile units can decrease barriers to screening for hard-to-reach populations 8 and that educational interventions associated with mobile unit visits can increase adherence.9 However, mobile units have different operating practices when compared to stationary (fixed) centres in terms of personnel, work conditions and environment. Moreover, screening in mobile units may require ongoing calibration of instruments, and where analogue units are used, films cannot be developed onsite. These differences could have an impact on screening outcomes but there are few studies comparing the performance of mobile units to fixed sites. 10,11 These studies focussed primarily on comparing costs and other elements (price, access, quality assurance). In some studies, screening results for mobile units were reported but were not compared to fixed centres. 8,[12][13][14] The aims of this study were to evaluate the contribution of mobile mammography units to participation rate, and to compare screening performance between mobile units and fixed centres in the organized mammography screening program of Quebec, Canada. METHODS Population and dataAll eligible women residing in the province, aged 50-69 years, are invited to participate in the Quebec breast cancer screening program. Each participant is asked to sign a written consent form to allow the collection of personal characteristics and screening information. Over the study period, 98% of participants provided written consent. ABSTRACT BACKGROUND: The aims of this study were to evaluate the contribution of mobile mammography units to participation rate and to compare their performance to fixed screening centres within the organized mammography screening program of Quebec, Canada.

“…8 These facilities provide screening at reduced cost and with more convenient appointment times and locations than fixed-site facilities. 7 Trained technicians supervise screening, as radiologists are usually not present. Films are read within a few days, and the women are contacted by either mail or telephone if they need further evaluation.…”

Patients can obtain screening mammograms without a physician's referral, leading to potential problems in clinical care. Because of the complexity of self-referral and the limitations of prior studies, we examined this phenomenon in a representative sample of mammography facilities. A questionnaire was given to all women obtaining mammograms at nine Connecticut mammography facilities during a 2-week period. Facilities included mobile sites, urban fixed sites, and rural fixed sites. Responses were categorized according to whether or not the woman had seen a primary care provider within the last year and whether or not she had received a recommendation to obtain a mammogram. The response rate was 62% (732 of 1,189), and the mean age of respondents was 58 years (range, 30-100 years). Self-referred women, defined as those without a recent visit to a primary care clinician and without a clinician's recommendation for a mammogram, constituted 6% of respondents. Self-referred women were significantly more likely to use mobile facilities (78% vs 33%, p Ͻ .01) and be under 50 years of age (44% vs 28%, p ‫؍‬ .02) compared with provider-referred women who had recently seen their provider. We conclude that younger women are obtaining screening mammograms without clear evidence of having seen their primary care provider in the previous year or having received a referral from their provider. Self-referral is especially common at mobile mammography facilities. Further study is needed to assess the clinical impact of self-referral on mass screening programs.

Abstract: Mobile mammography facilities compare favorably with stationary facilities. The use of these mobile units in the United States, however, has been limited.
