Developing and Testing an Electronic Measure of Screening Colonoscopy Overuse in a Large Integrated Healthcare System.

BACKGROUND: Most existing performance measures focus on underuse of care, but there is growing interest in identifying and reducing overuse. OBJECTIVE: We aimed to develop a valid and reliable electronic performance measure of overuse of screening colonoscopy in the Veterans Affairs Health Care System (VA), and to quantify overuse in VA. DESIGN: This was a cross-sectional study with multiple cross-sections. SUBJECTS: U.S. Veterans who underwent screening colonoscopy between 2011 and 2013. MAIN MEASURES: Overuse of screening colonoscopy, using a validated electronic measure developed by an expert workgroup. KEY RESULTS: Compared to results obtained from manual record review, the electronic measure was highly specific (97 %) for overuse, but not sensitive (20 %). After exclusion of diagnostic and high-risk screening or surveillance procedures, the validated electronic measure identified 88,754 average-risk screening colonoscopies performed in VA during 2013. Of these, 20,530 (23 %) met the definition for probable (17 %) or possible (6 %) overuse. Substantial variation in colonoscopy overuse was noted between Veterans Integrated Care Networks (VISNs) and between facilities, with a nearly twofold difference between the maximum and minimum rates of overuse at the VISN level and a nearly eightfold difference at the facility level. Overuse at the VISN and facility level was relatively stable over time. CONCLUSIONS: Overuse of screening colonoscopy can be measured reliably and with high specificity using electronic data, and is common in a large integrated healthcare system. Overuse measures, such as those we have specified through a consensus workgroup process, could be combined with underuse measures to improve the appropriateness of colorectal cancer screening.

Rates and correlates of potentially inappropriate colorectal cancer screening in the Veterans Health Administration.

BACKGROUND: Inappropriate use of colorectal cancer (CRC) screening procedures can inflate healthcare costs and increase medical risk. Little is known about the prevalence or causes of inappropriate CRC screening. OBJECTIVE: Our aim was to estimate the prevalence of potentially inappropriate CRC screening, and its association with patient and facility characteristics in the Veterans Health Administration (VHA) . DESIGN AND PARTICIPANTS: We conducted a cross-sectional study of all VHA patients aged 50 years and older who completed a fecal occult blood test (FOBT) or a screening colonoscopy between 1 October 2009 and 31 December 2011 (n = 1,083,965). MAIN MEASURES: Measures included: proportion of patients whose test was classified as potentially inappropriate; associations between potentially inappropriate screening and patient demographic and health characteristics, facility complexity, CRC screening rates, dependence on FOBT, and CRC clinical reminder attributes. KEY RESULTS: Of 901,292 FOBT cases, 26.1 % were potentially inappropriate (13.9 % not due, 7.8 % limited life expectancy, 11.0 % receiving FOBT when colonoscopy was indicated). Of 134,335 screening colonoscopies, 14.2 % were potentially inappropriate (10.4 % not due, 4.4 % limited life expectancy). Each additional 10 years of patient age was associated with an increased likelihood of undergoing potentially inappropriate screening (ORs = 1.60 to 1.83 depending on screening mode). Compared to facilities scoring in the bottom third on a measure of reliance on FOBT (versus screening colonoscopy), facilities scoring in the top third were less likely to conduct potentially inappropriate FOBTs (OR = 0.,78) but more likely to conduct potentially inappropriate colonoscopies (OR = 2.20). Potentially inappropriate colonoscopies were less likely to be conducted at facilities where primary care providers were assigned partial responsibility (OR = 0.74) or full responsibility (OR = 0.73) for completing the CRC clinical reminder. CONCLUSIONS: A substantial number of VHA CRC screening tests are potentially inappropriate. Establishing processes that enforce appropriate screening intervals, triage patients with limited life expectancies, and discourage the use of FOBTs when a colonoscopy is indicated may reduce inappropriate testing.

Using NCCN clinical practice guidelines in oncology to measure the quality of colorectal cancer care in the veterans health administration.

Clinical practice guidelines can be used to help develop measures of quality of cancer care. This article describes the use of a Cancer Care Quality Measurement System (CCQMS) to monitor these measures for colorectal cancer in the Veterans Health Administration (VHA). The CCQMS assessed practice guideline concordance primarily based on colon (14 indicators) and rectal (11 indicators) cancer care guidelines of the NCCN. Indicators were developed with input from VHA stakeholders with the goal of examining the continuum of diagnosis, neoadjuvant therapy, surgery, adjuvant therapy, and survivorship surveillance and/or end-of-life care. In addition, 9 measures of timeliness of cancer care were developed. The measures/indicators formed the basis of a computerized data abstraction tool that produced reports on quality of care in real-time as data were entered. The tool was developed for a 28-facility learning collaborative, the Colorectal Cancer Care Collaborative (C4), aimed at improving colorectal cancer (CRC) care quality. Data on 1373 incident stage I-IV CRC cases were entered over approximately 18 months and were used to target and monitor quality improvement activities. The primary opportunity for improvement involved surveillance colonoscopy and services in patients after curative-intent treatment. NCCN Clinical Practice Guidelines in Oncology were successfully used to develop a measurement system for a VHA research-operations quality improvement partnership.

Bringing an organizational perspective to the optimal number of colorectal cancer screening options debate.

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.

Levels and variation in overuse of fecal occult blood testing in the Veterans Health Administration.

BACKGROUND: Policy-makers have called for efforts to reduce overuse of cancer screening tests, including colorectal cancer screening (CRCS). Overuse of CRCS tests other than colonoscopy has not been well documented. OBJECTIVE: To estimate levels and correlates of fecal occult blood test (FOBT) overuse in a national Veterans Health Administration (VHA) sample. DESIGN: Observational PARTICIPANTS: Participants included 1,844 CRCS-eligible patients who responded to a 2007 CRCS survey conducted in 24 VHA facilities and had one or more FOBTs between 2003 and 2009. MAIN MEASURES: We combined survey data on race, education, and income with administrative data on region, age, gender, CRCS procedures, and outpatient visits to estimate overuse levels and variation. We coded FOBTs as overused if they were conducted <10 months after prior FOBT, <9.5 years after prior colonoscopy, or <4.5 years after prior barium enema. We used multinomial logistic regression models to examine variation in overuse by reason (sooner than recommended after prior FOBT; sooner than recommended after colonoscopy, barium enema, or a combination of procedures), adjusting for clustering of procedures within patients, and patients within facilities. KEY RESULTS: Of 4,236 FOBTs received by participants, 885 (21 %) met overuse criteria, with 323 (8 %) sooner than recommended after FOBT, and 562 (13 %) sooner than recommended after other procedures. FOBT overuse varied across facilities (9-32 %, p<0.0001) and region (12-23 %, p< .0012). FOBT overuse after prior FOBT declined between 2003 and 2009 (8 %-5 %, p= .0492), but overuse after other procedures increased (11-19 %, p= .0002). FOBT overuse of both types increased with number of outpatient visits (OR 1.15, p<0.001), but did not vary by patient demographics. More than 11 % of overused FOBTs were followed by colonoscopy within 12 months. CONCLUSIONS: Many FOBTs are performed sooner than recommended in the VHA. Variation in overuse by facility, region, and outpatient visits suggests addressing FOBT overuse will require system-level solutions.

Unintended consequences of implementing a national performance measurement system into local practice.

BACKGROUND: Although benefits of performance measurement (PM) systems have been well documented, there is little research on negative unintended consequences of performance measurement systems in primary care. To optimize PM systems, a better understanding is needed of the types of negative unintended consequences that occur and of their causal antecedents. OBJECTIVES: (1) Identify unintended negative consequences of PM systems for patients. (2) Develop a conceptual framework of hypothesized relationships between PM systems, facility-level variables (local implementation strategies, primary care staff attitudes and behaviors), and unintended negative effects on patients. DESIGN, PARTICIPANTS, APPROACH: Qualitative study design using dissimilar cases sampling. A series of 59 in-person individual semi-structured interviews at four Veterans Health Administration (VHA) facilities was conducted between February and July 2009. Participants included members of primary care staff and facility leaders. Sites were selected to assure variability in the number of veterans served and facility scores on national VHA performance measures. Interviews were recorded, transcribed and content coded to identify thematic categories and relationships. RESULTS: Participants noted both positive effects and negative unintended consequences of PM. We report three negative unintended consequences for patients. Performance measurement can (1) lead to inappropriate clinical care, (2) decrease provider focus on patient concerns and patient service, and (3) compromise patient education and autonomy. We also illustrate examples of negative consequences on primary care team dynamics. In many instances these problems originate from local implementation strategies developed in response to national PM definitions and policies. CONCLUSIONS: Facility-level strategies undertaken to implement national PM systems may result in inappropriate clinical care, can distract providers from patient concerns, and may have a negative effect on patient education and autonomy. Further research is needed to ascertain how features of centralized PM systems influence whether measures are translated locally by facilities into more or less patient-centered policies and processes.

Medical center characteristics associated with PSA screening in elderly veterans with limited life expectancy.

BACKGROUND: Although guidelines recommend against prostate-specific antigen (PSA) screening in elderly men with limited life expectancy, screening is common. OBJECTIVE: We sought to identify medical center characteristics associated with screening in this population. DESIGN/PARTICIPANTS: We conducted a prospective study of 622,262 screen-eligible men aged 70+ seen at 104 VA medical centers in 2003. MAIN MEASURES: Primary outcome was the percentage of men at each center who received PSA screening in 2003, based on VA data and Medicare claims. Men were stratified into life expectancy groups ranging from favorable (age 70-79 with Charlson score = 0) to limited (age 85+ with Charlson score ≥1 or age 70+ with Charlson score ≥4). Medical center characteristics were obtained from the 1999-2000 VA Survey of Primary Care Practices and publicly available VA data sources. KEY RESULTS: Among 123,223 (20%) men with limited life expectancy, 45% received PSA screening in 2003. Across 104 VAs, the PSA screening rate among men with limited life expectancy ranged from 25-79% (median 43%). Higher screening was associated with the following center characteristics: no academic affiliation (50% vs. 43%, adjusted RR = 1.14, 95% CI 1.04-1.25), a ratio of midlevel providers to physicians ≥3:4 (55% vs. 45%, adjusted RR = 1.20, 95% CI 1.09-1.32) and location in the South (49% vs. 39% in the West, adjusted RR = 1.25, 95% CI 1.12-1.40). Use of incentives and high scores on performance measures were not independently associated with screening. Within centers, the percentages of men screened with limited and favorable life expectancies were highly correlated (r = 0.90). CONCLUSIONS: Substantial practice variation exists for PSA screening in older men with limited life expectancy across VAs. The high center-specific correlation of screening among men with limited and favorable life expectancies indicates that PSA screening is poorly targeted according to life expectancy.

Evaluation of a VHA collaborative to improve follow-up after a positive colorectal cancer screening test.

BACKGROUND: In 2005, the Veterans Health Administration initiated a yearlong Colorectal Cancer Care Collaborative (C4) to improve timely follow-up after positive fecal occult blood tests. METHODS: Twenty-one facilities formed local quality improvement (QI) teams. Teams received QI training, created process flow maps, implemented process changes, and shared learning through 2 face-to-face meetings, conference calls, and a discussion board. We evaluated pre-post change in the timeliness of follow-up among C4 facilities and 3 control facilities. Outcome measures included the proportion of patients receiving a follow-up colonoscopy within 1 year, the proportion receiving 60-day follow-up (the focus of C4 teams), and average days to colonoscopy. Survey data from C4 team members was analyzed to identify predictors of facility-level improvement. RESULTS: Both C4 and control facilities improved on 1-year follow-up (10% and 9% increases, respectively, both P's<0.001). There was a statistically significant increase in the proportion receiving 60-day follow-up among C4 facilities (27% pre-C4 vs. 39% post-C4, P=0.008) but a nonsignificant decrease among control facilities (45% pre-C4 vs. 29% post-C4, P=0.14). Average days to colonoscopy decreased significantly among C4 facilities (129 pre-C4 vs. 103 post-C4, P=0.004) but increased significantly among control facilities (81 pre-C4 vs. 103 post-C4, P=0.04). Teams with the most improvement established clear roles/goals, had previous QI training, made more use of QI tools, and incorporated primary care education into their improvement work. CONCLUSIONS: A Veterans Health Administration improvement collaborative modestly decreased time to colonoscopy after a positive colorectal cancer screening test but significant room for improvement remains and benefits of participation were not realized by all facilities.

The interrelationships between and contributions of background, cognitive, and environmental factors to colorectal cancer screening adherence.

OBJECTIVES: We examined the interrelationships between and contributions of background, cognitive, and environmental factors to colorectal cancer (CRC) screening adherence. METHODS: In this study, 2,416 average risk patients aged 50-75 from 24 Veterans Affairs medical facilities responded to a mailed survey with phone follow-up (response rate 81%). Survey data (attitudes, behaviors, demographics) were linked to facility (organizational complexity) and medical records data (diagnoses, screening history). Patients with a fecal occult blood test within 15 months, sigmoidoscopy or barium enema within 5.5 years, or colonoscopy within 11 years of the survey were considered adherent. Logistic regressions estimated the association between adherence and background, cognitive, and environmental factors. Deviance ratios examined interrelationships between factors. Population attributable risks (PAR) were used to identify intervention targets. RESULTS: The association of background factors with adherence was partially explained by cognitive and environmental factors. The association of environmental factors with adherence was partially explained by cognitive factors. Cognitive and environmental factors contributed equally to adherence. Factors with the highest PARs for non-adherence were age 50-64, less than two comorbidities, and lack of physician recommendation. CONCLUSIONS: Efforts to increase physician screening recommendations for younger, healthy patients at facilities with the lowest screening rates may improve CRC adherence in this setting.

Mental health, frequency of healthcare visits, and colorectal cancer screening.

BACKGROUND: Research regarding the association between mental health and colorectal cancer (CRC) screening has produced mixed results. Variations may be explained by methodology, including whether potential confounders such as frequency of healthcare visits are considered. OBJECTIVE: We examined the association between mental health and CRC screening, before and after controlling for demographics, comorbidities, and outpatient visit frequency. DESIGN: Observational study based on a retrospective cohort. SUBJECTS: A total of 855 veterans receiving care at a Veterans Affairs Medical Center. MEASURES: Medical record data were used to assess CRC screening rates and mental health status (number of diagnoses and the presence of depression, anxiety, posttraumatic stress disorder, substance, or psychotic disorders). Logistic regression was used to estimate the association between mental health diagnoses and CRC screening, before and after controlling for covariates. RESULTS: Bivariate analyses suggested that CRC screening rates were higher for patients with a history of one or more mental health diagnoses (57% vs. 47%, P < 0.01). However, adjusting for timing of mental health diagnosis and outpatient visit frequency resulted in significant negative associations between CRC screening and all measures of mental health except posttraumatic stress disorder. CONCLUSIONS: Estimates of the association between mental health and CRC screening that do not adjust for outpatient visit frequency may be misleading. Veterans with mental health diagnoses were significantly less likely to be screened for CRC than their counterparts with no mental health diagnoses and an equal number of outpatient visits.

Developing and sustaining quality improvement partnerships in the VA: the Colorectal Cancer Care Collaborative.

OBJECTIVE: The Veterans Affairs (VA) Quality Enhancement Research Initiative (QUERI) seeks to develop partnerships between VA health services researchers and clinical managers, with the goal of designing and evaluating interventions to improve the quality of VA health care. METHODS: In the present report we describe one such initiative aimed at enhancing the continuum of colorectal cancer (CRC) care, including diagnosis, treatment and surveillance-the Colorectal Cancer Care Collaborative (C4). RESULTS: We describe the process and thinking that led to two parallel quality improvement "collaboratives" that addressed (1) CRC screening and diagnostic follow-up and (2) the guideline concordance and timeliness of CRC treatment. Additionally, we discuss ongoing effort to spread lessons learned during the first stages of the project, which initially occurred at only a subset of VA facilities, throughout the VA health care system. The description of this initiative is organized around key questions that must be answered when developing, sustaining and spreading multi-component quality improvement interventions. CONCLUSION: We conclude with a discussion of lessons learned that we believe would apply to similar initiatives elsewhere, even if they address different clinical issues in health care settings with different organizational structures.

Hospital characteristics associated with timeliness of care in veterans with lung cancer.

RATIONALE: Timeliness is one of six important dimensions of health care quality recognized by the Institute of Medicine. OBJECTIVES: To evaluate timeliness of lung cancer care and identify institutional characteristics associated with timely care within the Veterans Affairs (VA) health care system. METHODS: We used data from a VA nation-wide retrospective chart review and an independent audit of VA cancer programs to examine the association between time to first treatment and potentially explanatory institutional characteristics (e.g., volume of lung cancer patients) for 2,372 veterans diagnosed with lung cancer between 1 January 2002 and 1 September 2005 at 127 VA medical centers. We developed linear mixed effects models to control for clustering of patients within hospitals and we stratified analyses by stage. MEASUREMENTS AND MAIN RESULTS: Median time to treatment varied widely between (23 to 182 d) and within facilities. Median time to treatment was 90 days in patients with stage I or II cancer and 52 days in those with more advanced disease (P < 0.0001). Factors associated with shorter times to treatment included a nonacademic setting and the existence of a specialized diagnostic clinic (in patients with limited-stage disease), performing a patient flow analysis (in patients with advanced disease), and leadership beliefs about providing timely care (in both groups). However, institutional characteristics explained less than 1% of the observed variation in treatment times. CONCLUSIONS: Time to lung cancer treatment in U.S. veterans is highly variable. The numerous institutional characteristics we examined explained relatively little of this variability, suggesting that patient, clinician, and/or unmeasured institutional characteristics may be more important determinants of timely care.

Race and the validity of self-reported cancer screening behaviors: development of a conceptual model.

BACKGROUND: Many estimates of cancer screening are based on self-reported screening behavior. There is growing concern that self-reported screening measures may be less accurate among members of racial and ethnic minority groups. This would have considerable implications for research on racial and ethnic disparities in cancer screening. OBJECTIVES: To review the literature on the relationship between race/ethnicity and the accuracy of self-reported cancer screening behavior and develop a conceptual framework that would provide a deeper understanding of factors underlying this relationship. METHODS: We developed a conceptual framework drawing from diverse literatures including validation studies examining the accuracy of self-reported cancer screening behaviors and articles on survey response bias. RESULTS AND CONCLUSIONS: Evidence suggests that racial and ethnic minorities may be less likely to provide accurate reports of their cancer screening behavior and that overreporting may be particularly problematic. Research conducted in other areas suggests that these sources of measurement error may stem from cognitive and motivational processes and that they can be moderated by question wording and data collection characteristics. At this point, however, the quality of the evidence is not strong and more research is needed before definitive conclusions can be drawn.

Colorectal cancer screening mode preferences among US veterans.

OBJECTIVE: To assess colorectal cancer (CRC) screening mode preferences and correlates of these preferences among US veterans at average risk for CRC. METHOD: A cross-sectional survey of a nationally representative sample of VA patients was conducted between January 2005 and December 2006. We report preference distributions for screening modes among 2068 average-risk veterans and across patient subgroups based on personal, behavioral, and environmental factors. Independent predictors of preferences are identified through hierarchical logistic regression models. RESULTS: Colonoscopy (37%) was the most preferred mode followed by fecal occult blood test (FOBT) (29%). The strongest predictors of preferences were previous screening experience, provider recommendation, and use of non-VA healthcare services. Participants in higher socioeconomic groups were more likely to choose colonoscopy and less likely to indicate no preference. CONCLUSION: Screening programs that offer only one mode fail to accommodate the preferences of a substantial proportion of patients. Within the VA, adding screening colonoscopy to programs currently offering only FOBT is likely to increase preferences for colonoscopy, as patients incorporate provider recommendations for and personal experience with colonoscopy into their preferences. This is likely to disproportionately benefit lower socioeconomic groups who do not currently have access to non-VA colonoscopy services.

Validation of self-reported colorectal cancer screening behavior from a mixed-mode survey of veterans.

OBJECTIVE: The aim of the study was to validate self-reported colorectal cancer (CRC) screening using the National Cancer Institute Colorectal Cancer Screening questionnaire. MATERIALS AND METHODS: 890 patients, ages 50 to 75 years, from the Minneapolis Veterans Affairs (VA) Medical Center were surveyed by mail. Phone administration was attempted with mail nonresponders. VA and non-VA records were combined for the reference standard. Sensitivity, specificity, concordance, and report-to-records ratio (R2R) were estimated for overall and test-specific CRC adherence among respondents providing complete medical records. Secondary analyses examined variation in estimates by patient characteristics, treatment of missing and uncertain responses, and whether a strict or liberal time interval was used for assessing concordance. RESULTS: Complete medical records were available for 345 of the 686 survey responders. For overall adherence, sensitivity was 0.98, specificity was 0.59, concordance was 0.88, and R2R was 1.14. Sensitivity was 0.82 for fecal occult blood test (FOBT), 0.75 for sigmoidoscopy, 0.97 for colonoscopy, and 0.63 for double-contrast barium enema (DCBE). Specificity was 0.89 for FOBT, 0.76 for sigmoidoscopy, 0.72 for colonoscopy, and 0.85 for DCBE. Concordance was >0.80 for all tests other than sigmoidoscopy (0.76). R2R was 1.31 for FOBT, 1.33 for sigmoidoscopy, 1.42 for colonoscopy, and 6.13 for DCBE. The R2R was lower for a combined sigmoidoscopy and colonoscopy measure. Overreporting was more pronounced for older, less-educated individuals with no family history of CRC. Sensitivity and R2R improved using a liberal interval and treating uncertain responses as nonadherent (versus missing), but differences were not statistically significant. CONCLUSIONS: Self-reported CRC screening validity is generally acceptable and robust across definitional decisions, but varies by screening test and patient characteristics.

Inequality as ingroup privilege or outgroup disadvantage: the impact of group focus on collective guilt and interracial attitudes.

Among members of privileged groups, social inequality is often thought of in terms of the disadvantages associated with outgroup membership. Yet inequality also can be validly framed in terms of ingroup privilege. These different framings have important psychological and social implications. In Experiment 1 (N = 110), White American participants assessed 24 statements about racial inequality framed as either White privileges or Black disadvantages. In Experiment 2 (N = 122), White participants generated examples of White privileges or Black disadvantages. In both experiments, a White privilege framing resulted in greater collective guilt and lower racism compared to a Black disadvantage framing. Collective guilt mediated the manipulation's effect on racism. In addition, in Experiment 2, a White privilege framing decreased White racial identification compared to a Black disadvantage framing. These findings suggest that representing inequality in terms of outgroup disadvantage allows privileged group members to avoid the negative psychological implications of inequality and supports prejudicial attitudes.

Adding Postal Follow-Up to a Web-Based Survey of Primary Care and Gastroenterology Clinic Physician Chiefs Improved Response Rates but not Response Quality or Representativeness.

This study assessed whether postal follow-up to a web-based physician survey improves response rates, response quality, and representativeness. We recruited primary care and gastroenterology chiefs at 125 Veterans Affairs medical facilities to complete a 10-min web-based survey on colorectal cancer screening and diagnostic practices in 2010. We compared response rates, response errors, and representativeness in the primary care and gastroenterology samples before and after adding postal follow-up. Adding postal follow-up increased response rates by 20-25 percentage points; markedly greater increases than predicted from a third e-mail reminder. In the gastroenterology sample, the mean number of response errors made by web responders (0.25) was significantly smaller than the mean number made by postal responders (2.18), and web responders provided significantly longer responses to open-ended questions. There were no significant differences in these outcomes in the primary care sample. Adequate representativeness was achieved before postal follow-up in both samples, as indicated by the lack of significant differences between web responders and the recruitment population on facility characteristics. We conclude adding postal follow-up to this web-based physician leader survey improved response rates but not response quality or representativeness.

Organizational predictors of colonoscopy follow-up for positive fecal occult blood test results: an observational study.

BACKGROUND: This study assessed the contribution of organizational structures and processes identified from facility surveys to follow-up for positive fecal occult blood tests [FOBT-positive (FOBT(+))]. METHODS: We identified 74,104 patients with FOBT(+) results from 98 Veterans Health Administration (VHA) facilities between August 16, 2009 and March 20, 2011, and followed them until September 30, 2011, for completion of colonoscopy. We identified patient characteristics from VHA administrative records, and organizational factors from facility surveys completed by primary care and gastroenterology chiefs. We estimated predictors of colonoscopy completion within 60 days and six months using hierarchical logistic regression models. RESULTS: Thirty percent of patients with FOBT(+) results received colonoscopy within 60 days and 49% within six months. Having gastroenterology or laboratory staff notify gastroenterology providers directly about FOBT(+) cases was a significant predictor of 60-day [odds ratio (OR), 1.85; P = 0.01] and six-month follow-up (OR, 1.25; P = 0.008). Additional predictors of 60-day follow-up included adequacy of colonoscopy appointment availability (OR, 1.43; P = 0.01) and frequent individual feedback to primary care providers about FOBT(+) referral timeliness (OR, 1.79; P = 0.04). Additional predictors of six-month follow-up included using guideline-concordant surveillance intervals for low-risk adenomas (OR, 1.57; P = 0.01) and using group appointments and combined verbal-written methods for colonoscopy preparation instruction (OR, 1.48; P = 0.0001). CONCLUSION: Directly notifying gastroenterology providers about FOBT(+) results, using guideline-concordant adenoma surveillance intervals, and using colonoscopy preparations instruction methods that provide both verbal and written information may increase overall follow-up rates. Enhancing follow-up within 60 days may require increased colonoscopy capacity and feedback to primary care providers. IMPACT: These findings may inform organizational-level interventions to improve FOBT(+) follow-up.
