A critical challenge facing cancer screening programs, particularly those aimed at uninsured people with low incomes, is choosing the screening test that makes the most efficient use of limited budgets. For colorectal cancer screening, there is growing momentum to use colonoscopy, which is an expensive test. In this study, we modeled scenarios to assess whether the use of fecal occult blood tests or colonoscopy provides the most benefit under conditions of budget constraints. We found that although colonoscopy is more accurate, under most scenarios, fecal occult blood tests would result in more individuals' getting screened, with more life-years gained.
    • Both administrators and specialists had concerns about limitations in colonoscopy resources, and how the organization should manage these resources while still offering screening to all eligible patients . Resource constraints are likely to remain an ongoing concern in colorectal cancer screening programs [56,57].
    [Show abstract] [Hide abstract] ABSTRACT: Background Few studies describe system-level challenges or facilitators to implementing population-based colorectal cancer (CRC) screening outreach programs. Our qualitative study explored viewpoints of multilevel stakeholders before, during, and after implementation of a centralized outreach program. Program implementation was part of a broader quality-improvement initiative. Methods During 2008–2010, we conducted semi-structured, open-ended individual interviews and focus groups at Kaiser Permanente Northwest (KPNW), a not-for-profit group model health maintenance organization using the practical robust implementation and sustainability model to explore external and internal barriers to CRC screening. We interviewed 55 stakeholders: 8 health plan leaders, 20 primary care providers, 4 program managers, and 23 endoscopy specialists (15 gastroenterologists, 8 general surgeons), and analyzed interview transcripts to identify common as well as divergent opinions expressed by stakeholders. Results The majority of stakeholders at various levels consistently reported that an automated telephone-reminder system to contact patients and coordinate mailing fecal tests alleviated organizational constraints on staff’s time and resources. Changing to a single-sample fecal immunochemical test (FIT) lessened patient and provider concerns about feasibility and accuracy of fecal testing. The centralized telephonic outreach program did, however, result in some screening duplication and overuse. Higher rates of FIT completion and a higher proportion of positive results with FIT required more colonoscopies. Conclusions Addressing barriers at multiple levels of a health system by changing the delivery system design to add a centralized outreach program, switching to a more accurate and easier-to-use fecal test, and providing educational and electronic support had both benefits and problematic consequences. Other health care organizations can use our results to understand the complexities of implementing centralized screening programs.

    • During the period we study, colonoscopy technology transitioned from being a " gold standard " promoted by the American College of Gastroenterology (Rex et al., 2009) to one increasingly questioned by the mounting evidence base, especially in the face of considerable risks posed to older persons from the procedure itself (Whitlock et al., 2008). Now that rising budget deficits are looming, economists are questioning the costeffectiveness of colonoscopy and providing more evidence against it (Subramanian et al., 2010; Goodwin et al., 2011). Perhaps in this time of increased cost-consciousness, managed care practices will return to positions of influence and imbue more constraint on the diffusion of cost-increasing technologies.
    [Show abstract] [Hide abstract] ABSTRACT: To determine whether Medicare managed care penetration impacted the diffusion of endoscopy services (sigmoidoscopy, colonoscopy) among the fee-for-service (FFS) Medicare population during 2001-2006. We model utilization rates for colonoscopy or sigmoidoscopy as impacted by both market supply and demand factors. We use spatial regression to perform ecological analysis of county-area utilization rates over two time intervals (2001-2003, 2004-2006) following Medicare benefits expansion in 2001 to cover colonoscopy for persons of average risk. We examine each technology in separate cross-sectional regressions estimated over early and later periods to assess differential effects on diffusion over time. We discuss selection factors in managed care markets and how failure to control perfectly for market selection might impact our managed care spillover estimates. Areas with worse socioeconomic conditions have lower utilization rates, especially for colonoscopy. Holding constant statistically the socioeconomic factors, we find that managed care spillover effects onto FFS Medicare utilization rates are negative for colonoscopy and positive for sigmoidoscopy. The spatial lag estimates are conservative and interpreted as a lower bound on true effects. Our findings suggest that managed care presence fostered persistence of the older technology during a time when it was rapidly being replaced by the newer technology.

  • [Show abstract] [Hide abstract] ABSTRACT: Health disparities, also known as health inequities, are systematic and potentially remediable differences in one or more aspects of health across population groups defined socially, economically, demographically, or geographically. This topic has been the subject of research stretching back at least decades. Reports and studies have delved into how inequities develop in different societies and, with particular regard to health services, in access to and financing of health systems. In this review, we consider empirical studies from the United States and elsewhere, and we focus on how one aspect of health systems, clinical care, contributes to maintaining systematic differences in health across population groups characterized by social disadvantage. We consider inequities in clinical care and the policies that influence them. We develop a framework for considering the structural and behavioral components of clinical care and review the existing literature for evidence that is likely to be generalizable across health systems over time. Starting with the assumption that health services, as one aspect of social services, ought to enhance equity in health care, we conclude with a discussion of threats to that role and what might be done about them.

  • [Show abstract] [Hide abstract] ABSTRACT: Improving colorectal cancer (CRC) screening rates represents a challenge for primary care providers. Some have argued that offering a choice of CRC screening modes to patients will improve the currently low adherence rates. Others have raised concerns that offering numerous CRC screening options in practice could overwhelm patients and thus dampen enthusiasm for screening. In this article we assemble evidence to critically evaluate the relative merit of these opposing views. We find little evidence to support the hypothesis that the number of options offered will affect adherence (either positively or negatively), or that expanding the modalities offered beyond FOBT and colonoscopy will improve patient satisfaction. Therefore, we assert future decisions about the number of CRC screening modes to offer would more productively be focused on considerations such as what benefit the health-care organization would derive from offering additional modes, and how this change would affect other critical components of a successful screening program such as timely diagnosis. In light of these organizational level considerations, we agree with the assertion made by others that a screening program limited to FOBT and colonoscopy is likely to be ideal in most settings.

  • [Show abstract] [Hide abstract] ABSTRACT: Rising colorectal cancer (CRC) screening rates in the last decade are attributable almost entirely to increased colonoscopy use. Little is known about factors driving the increase, but primary care physicians (PCPs) play a central role in CRC screening delivery. Explore PCP attitudes toward screening colonoscopy and their associations with CRC screening practice patterns. Cross-sectional analysis of data from a nationally representative survey conducted in 2006-2007. 1,266 family physicians, general practitioners, general internists, and obstetrician-gynecologists. Physician-reported changes in the volume of screening tests ordered, performed or supervised in the past 3 years, attitudes toward colonoscopy, the influence of evidence and perceived norms on their recommendations, challenges to screening, and practice characteristics. The cooperation rate (excludes physicians without valid contact information) was 75%; 28% reported their volume of FOBT ordering had increased substantially or somewhat, and the majority (53%) reported their sigmoidoscopy volume decreased either substantially or somewhat. A majority (73%) reported that colonoscopy volume increased somewhat or substantially. The majority (86%) strongly agreed that colonoscopy was the best of the available CRC screening tests; 69% thought it was readily available for their patients; 59% strongly or somewhat agreed that they might be sued if they did not offer colonoscopy to their patients. All three attitudes were significantly related to substantial increases in colonoscopy ordering. PCPs report greatly increased colonoscopy recommendation relative to other screening tests, and highly favorable attitudes about colonoscopy. Greater emphasis is needed on informed decision-making with patients about preferences for test options.

  • [Show abstract] [Hide abstract] ABSTRACT: PURPOSEWe evaluated the Colorectal Cancer (CRC) Oncology Watch intervention, a clinical reminder implemented in Veterans Integrated Service Network 7 (including eight hospitals) to improve CRC screening rates in 2008. PATIENTS AND METHODS Veterans Affairs (VA) administrative data were used to construct four cross-sectional groups of veterans at average risk, age 50 to 64 years; one group was created for each of the following years: 2006, 2007, 2009, and 2010. We applied hospital fixed effects for estimation, using a difference-in-differences model in which the eight hospitals served as the intervention sites, and the other 121 hospitals served as controls, with 2006 to 2007 as the preintervention period and 2009 to 2010 as the postintervention period.ResultsThe sample included 4,352,082 veteran-years in the 4 years. The adherence rates were 37.6%, 31.6%, 34.4%, and 33.2% in the intervention sites in 2006, 2007, 2009, and 2010, respectively, and the corresponding rates in the controls were 31.0%, 30.3%, 32.3%, and 30.9%. Regression analysis showed that among those eligible for screening, the intervention was associated with a 2.2-percentage point decrease in likelihood of adherence (P < .001). Additional analyses showed that the intervention was associated with a 5.6-percentage point decrease in likelihood of screening colonoscopy among the adherent, but with increased total colonoscopies (all indicators) of 3.6 per 100 veterans age 50 to 64 years. CONCLUSION The intervention had little impact on CRC screening rates for the studied population. This absence of favorable impact may have been caused by an unintentional shift of limited VA colonoscopy capacity from average-risk screening to higher-risk screening and to CRC surveillance, or by physician fatigue resulting from the large number of clinical reminders implemented in the VA.

Obtaining regular screening exams can significantly reduce colorectal cancer (CRC) mortality. Most CRC models to date have assumed "ideal conditions" such as 100% compliance, and the effects of CRC screening tests have been assessed only under these conditions. In this study, we assess cost-effectiveness incorporating real-world patient preferences and compliance. Methodology: We built an... [Show full abstract]

Agent-Based Models (ABMs) can be used to quantify future risks by projecting observable behavior into the future. This can be achieved by simulating a hypothetical longitudinal study based on cross-sectional data and estimating quantities on dynamic risks (e.g., relative hazard). Such an approach, however, requires assessment of the variation of the estimates, which would naturally have a... [Show full abstract]
