Improvement in colon cancer screening through use of a multilevel intervention: A QI initiative

Practice Transformation to Improve Cancer Screening Outcomes at an Academic Medical Center

In 2011, Texas received federal approval of the 1115 Healthcare Transformation waiver, which went to support the Texas Delivery System Reform Incentive Payment Program (DSRIP) incentivizing the transformation of service delivery practices which included expanded coverage of preventive cancer screenings. There is limited evidence that quality improvement initiatives stemming from DSRIP improve cancer screening outcomes for the Medicaid, low-income, and uninsured (MLIU) patient population. The present the results of a quality initiative to improve breast, cervical, and colorectal cancer screening rates for MLIU patients receiving primary care at an academic medical center. The initiative included engaging multidisciplinary primary care teams, health information technology (IT), and quality departments to standardize workflows. We found significantly improved rates of cervical and colorectal cancer screening among patients eligible to receive one or more screenings. Aligning primary care, IT, and quality processes resulted in significant improvement in cancer screening.

Randomized Clinical Trial of Inreach With or Without Mailed Outreach to Promote Hepatitis C Screening in a Difficult-to-Reach Patient Population

INTRODUCTION

Hepatitis C virus (HCV) treatment can significantly reduce the risk of liver-related mortality; however, many patients remain unaware of their infection in clinical practice. The aim of this study is to compare the effectiveness of inreach, with and without mailed outreach, to increase HCV screening and follow-up in a large, difficult-to-reach patient population.

METHODS

We conducted a pragmatic randomized clinical trial from August 2018 to May 2019 in a large safety-net health system. Patients born between 1945 and 1965 were randomly assigned (1:1) to inreach with an electronic health record reminder to providers (n = 6,195) or inreach plus mailed HCV screening outreach (n = 6,191) to complete HCV antibody screening. Outreach also included processes to promote HCV RNA testing among those with a positive HCV antibody and linkage to care among those with positive HCV RNA. The primary outcome was completion of HCV antibody testing within 3 months of randomization (ClinicalTrials.gov NCT03706742).

RESULTS

We included 12,386 eligible patients (median age 60 years; 46.5% Hispanic, 33.0% Black, and 16.0% White). In intent-to-treat analyses, HCV screening completion was significantly higher among inreach-plus-outreach patients than inreach-alone patients at 3 months (14.6% vs 7.4%, P < 0.001) and 6 months (17.4% vs 9.8%, P < 0.001) after randomization. Among those who completed HCV screening within 6 months, a higher proportion of inreach-plus-outreach patients with positive antibody results completed RNA testing within 3 months than inreach-alone patients (81.1% vs 57.1%, respectively, P = 0.02); however, linkage to care within 3 months of HCV infection confirmation did not significantly differ between the 2 groups (48.1% vs 75.0%, respectively, P = 0.24).

DISCUSSION

Among difficult-to-reach patients, a combination of inreach and mailed outreach significantly increased HCV screening compared with inreach alone. However, HCV screening completion in both arms remained low, highlighting a need for more intensive interventions.

Patient perspectives on colorectal cancer screening and the role of general practice

Background

Colorectal cancer (CRC) is the second most frequent cause of cancer death in Australia. Early detection can reduce incidence and mortality. General practice-based initiatives have been proposed to improve CRC screening rates but to date have had modest impact. As there is limited research into the patient experience of CRC screening decision making, this study explored patient perspectives on CRC screening and the potential role for general practice.

Methods

Ten participants, aged between 50 and 74, from a general practice in South Australia were recruited by practice staff. Semi-structured interviews were conducted. Concurrent data collection and analysis were performed, guided by interpretative phenomenological analysis.

Results

Two key themes were evident: attitudes toward screening and potential roles for general practice. Participants structured the experience of screening in terms of being proactive, ambivalent or avoidant. Roles for general practice centred on tasks as educators, trusted advisors, monitors and screeners. Mixed views on whether general practice involvement was necessary prompted consideration of additional sources of health information and motivation around screening.

Conclusions

Exploration of the patient experience provides insight into how participants make sense of screening and perceived roles for general practice (or other agents) in screening. There is satisfaction with current Government-driven processes but perceived value in general practice playing a complementary part in increasing screening rates. A multifaceted strategy, accounting for attitudes, is required to improve screening and population health outcomes.

A Multi-Level Fit-Based Quality Improvement Initiative to Improve Colorectal Cancer Screening in a Managed Care Population

Introduction

Colorectal cancer (CRC) is a common but largely preventable disease with suboptimal screening rates despite national guidelines to screen individuals age 50–75. Single-component interventions aimed to improve screening uptake only modestly improve rates; data suggest that multi-modal approaches may be more effective.

Methods

We designed, implemented, and evaluated the impact of a multi-modal intervention on CRC screening uptake among unscreened patients in a large managed care population. Patient-level components included a mailed letter with education about screening options and pre-colonoscopy telephone counseling. For providers, we facilitated communication of screening test results and work-flow for abnormal results. System-level modifications included establishment of a patient navigator, expedited work-up for abnormal results, and stream-lined colonoscopy scheduling. We measured the rate of screening uptake overall, screening uptake by modality, change in the proportion of the population screened, and positive fecal immunochemical test (FIT) follow-up rates in the 1-year study period.

Results

There were 5093 patients in the intervention cohort. Of these, 33.2% participated in FIT or colonoscopy screening within 1 year of the mailing. A total of 1078 (21.2%) participants completed a FIT and 611 (12.0%) completed a screening colonoscopy. The screening rate in the managed care population increased from 65.1 to 76.6%. Fifty-nine patients (5.5%) had a positive FIT, of which 30 (50.8%) completed a diagnostic colonoscopy.

Conclusion

Multi-modal interventions can result in substantial improvement in CRC screening uptake in large and diverse managed care populations.

Translational Impact

Health systems should shift their focus from single-level to multi-level interventions when addressing barriers to CRC screening.
