Components and effectiveness of patient navigation programmes to increase participation to breast, cervical and colorectal cancer screening: A systematic review

Assessment of barriers to cancer screening and interventions implemented to overcome these barriers in 27 Latin American and Caribbean countries

There is a gap in the understanding of the barriers to cancer screening participation and complying with downstream management in the Community of Latin American and Caribbean states (CELAC). Our study aimed to assess barriers across the cancer screening pathway from the health system perspective, and interventions in place to improve screening in CELAC. A standardized tool was used to collect information on the barriers across the screening pathway through engagement with the health authorities of 27 member states of CELAC. Barriers were organized in a framework adapted from the Tanahashi conceptual model and consisted of the following dimensions: availability of services, access (covering accessibility and affordability), acceptability, user-provider interaction, and effectiveness of services (which includes governance, protocols and guidelines, information system, and quality assurance). The tool also collected information of interventions in place, categorized in user-directed interventions to increase demand, user-directed interventions to increase access, provider-directed interventions, and policy and system-level interventions. All countries prioritized barriers related to the information systems, such as the population register not being accurate or complete (N = 19; 70.4%). All countries implemented some kind of intervention to improve cancer screening, group education being the most reported (N = 23; 85.2%). Training on screening delivery was the most referred provider-directed intervention (N = 19; 70.4%). The study has identified several barriers to the implementation of cancer screening in the region and interventions in place to overcome some of the barriers. Further analysis is required to evaluate the effectiveness of these interventions in achieving their objectives.

Supporting ColoREctal Equitable Navigation (SCREEN): a protocol for a stepped-wedge cluster randomized trial for patient navigation in primary care

BACKGROUND

Black individuals in the United States (US) have a higher incidence of and mortality from colorectal cancer (CRC) compared to other racial groups, and CRC is the second leading cause of death among Hispanic/Latino populations in the US. Patient navigation is an evidence-based approach to narrow inequities in cancer screening among Black and Hispanic/Latino patients. Despite this, limited healthcare systems have implemented patient navigation for screening at scale.

METHODS

We are conducting a stepped-wedge cluster randomized trial of 15 primary care clinics with six steps of six-month duration to scale a patient navigation program to improve screening rates among Black and Hispanic/Latino patients. After six months of baseline data collection with no intervention we will randomize clinics, whereby three clinics will join the intervention arm every six months until all clinics cross over to intervention. During the intervention roll out we will conduct training and education for clinics, change infrastructure in the electronic health record, create stakeholder relationships, assess readiness, and deliver iterative feedback. Framed by the Practical, Robust Implementation Sustainment Model (PRISM) we will focus on effectiveness, reach, provider adoption, and implementation. We will document adaptations to both the patient navigation intervention and to implementation strategies. To address health equity, we will engage multilevel stakeholder voices through interviews and a community advisory board to plan, deliver, adapt, measure, and disseminate study progress. Provider-level feedback will include updates on disparities in screening orders and completions.

DISCUSSION

Primary care clinics are poised to close disparity gaps in CRC screening completion but may lack an understanding of the magnitude of these gaps and how to address them. We aim to understand how to tailor a patient navigation program for CRC screening to patients and providers across diverse clinics with wide variation in baseline screening rates, payor mix, proximity to specialty care, and patient volume. Findings from this study will inform other primary care practices and health systems on effective and sustainable strategies to deliver patient navigation for CRC screening among racial and ethnic minorities.

Increasing Uptake of Lung Cancer Screening Among Emergency Department Patients: A Pilot Study

BACKGROUND

Lung cancer is the leading cause of cancer death in the United States. Lung cancer screening (LCS) decreases lung cancer mortality. Emergency department (ED) patients are at disproportionately high risk for lung cancer. The ED, therefore, is an optimal environment for interventions to promote LCS.

OBJECTIVES

Demonstrate the operational feasibility of identifying ED patients in need of LCS, referring them to LCS services, deploying a text message intervention to promote LCS, and conducting follow-up to determine LCS uptake.

METHODS

We conducted a randomized clinical trial to determine the feasibility and provide estimates of the preliminary efficacies of 1) basic referral for LCS and 2) basic referral plus a text messaging intervention, grounded in behavioral change theory, to promote uptake of LCS among ED patients. Participants aged 50 to 80, identified as eligible for LCS, were randomized to study arms and followed up at 150 days to assess interval LCS uptake (primary outcome), barriers to screening, and perceptions of the study interventions.

RESULTS

A total of 303 patients were surveyed, with 198 identified as eligible for LCS and subsequently randomized. Results indicated that 24% of participants with follow-up data received LCS (11% of the total randomized sample). Rates of screening at follow-up were similar across study arms. The intervention significantly improved normative perceptions of LCS (p = 0.015; Cohen's d = 0.45).

CONCLUSION

This pilot study demonstrates the feasibility of ED-based interventions to increase uptake of LCS among ED patients. A scalable ED-based intervention that increases LCS uptake could reduce lung cancer mortality.

Patient navigation in women's health care for maternal health and noncancerous gynecologic conditions: a scoping review

PURPOSE

This study investigated the scope of patient navigation studies on women's health care for maternal health and noncancerous gynecologic conditions and aimed to report the characteristics of the identified patient navigation programs.

METHODS

A scoping review was conducted following Arksey and O'Malley's framework. Five electronic databases were searched for relevant studies published in English: PubMed, Embase, Cochrane Library, CINAHL, and PsycInfo. There were no restrictions on the publication date and the search was completed in July 2023.

RESULTS

This scoping review included 14 studies, which collectively examined seven patient navigation programs. All selected studies were related to maternal health issues (e.g., perinatal health problems and contraception for birth spacing). Close to two-thirds of the patient navigation services were provided by women (n=9, 64.3%) and half by lay navigators (n=7, 50.0%). The majority incorporated the use of mobile health technologies (n=11, 78.6%). All of the patient navigation programs included in the review coordinated the necessary clinical and social support services to improve women's access to care.

CONCLUSION

Patient navigation appears to be in its nascent phase in the field of maternal health. The results of this study suggest that the implementation of patient navigation services could potentially improve access to care for socially disadvantaged women and families. Furthermore, providing patient navigation services that are specifically tailored to meet women's needs could improve the quality of maternity care.

Advancing health equity in improving breast cancer screening with the use of a mobile mammography bus in marginalised population: quality improvement project

BACKGROUND

Breast cancer, the second leading cause of cancer-related deaths in women in the USA, is effectively treated through early detection and screening. This quality improvement (QI) project aimed to improve mammography screening rates from the baseline of 50% to 60% within 12 months for patients aged 50-74 years at an Internal Medicine Clinic.

METHODS

We used the Plan, Do, Study, Act (PDSA) model. A multidisciplinary team used a fishbone diagram to identify barriers to suboptimal screening. The QI team created a driver diagram and process flow map. The mammogram screening rate was the outcome measure. Mammogram order and completion rates were the process measures. We implemented six PDSA cycles. Major interventions included the use of a nurse navigator, enhancements in health information technology, and education to patients, providers, and nursing staff. Mammograms were offered in a mobile bus, located in the hospital campus and in under-resourced inner-city neighbourhoods to improve the access. Data analysis was performed using monthly statistical process control charts.

RESULTS

The project exceeded its initial goal, achieving a breast cancer screening rate of 66% (n=490 of 744) during the study period and was sustainable at 69%, 3 months post-project. The mammogram order rate was 58% (n=432 of 744) and completion rate was 53% (n=231 of 432) within 12 months.

CONCLUSIONS

We attributed the success of this QI project to the education of patients, nurses and physicians, the use of a nurse navigator and engagement of a multidisciplinary team. Access to mobile mammography bus addressed the social determinants of health barriers in a marginalised population.

Effect of Behavioral Interventions on the Uptake of Colonoscopy for Colorectal Cancer Screening: A Systematic Review and Meta-Analysis

INTRODUCTION

Screening decreases colorectal cancer incidence and mortality, but uptake in the United States remains suboptimal. Prior studies have investigated the effect of various interventions on overall colorectal cancer screening and stool-based testing, but the effect on colonoscopy-the predominant screening test in the United States-has not been fully examined. We performed a systematic review and meta-analysis to assess the effect of behavioral interventions on screening colonoscopy uptake.

METHODS

We searched PubMed, Embase, and Cochrane databases through January 2022 for controlled trials that assessed the effect of behavioral interventions on screening colonoscopy uptake. All titles, abstracts, and articles were screened by at least 2 independent reviewers. Odds ratios were extracted from the original article or calculated from the raw data. The primary outcome was the relative increase in screening colonoscopy completion with any behavioral intervention. We performed random-effects meta-analysis, with subgroup analysis by type of intervention.

RESULTS

A total of 25 studies with 30 behavioral interventions were analyzed. The most common interventions were patient navigation (n = 11) and multicomponent interventions (n = 6). Overall, behavioral interventions increased colonoscopy completion by 54% compared with controls (odds ratio [OR] 1.54, 95% confidence interval [CI] 1.26-1.88). Patient navigation (OR 1.78, 95% CI 1.35-2.34) and multicomponent interventions (OR 1.84, 95% CI 1.17-2.89) had the strongest effect on colonoscopy completion among interventions examined in multiple studies. Significant heterogeneity was observed both overall and by intervention type. There was no evidence of publication bias.

DISCUSSION

Behavioral interventions increase screening colonoscopy completion and should be adopted in clinical practice. In particular, patient navigation and multicomponent interventions are the best-studied and most effective interventions.
