Abstract

Purpose: Colonoscopy can prevent morbidity and mortality from colorectal cancer (CRC) and is the most commonly used screening method in the United States. Barriers to colonoscopy at multiple levels can contribute to disparities. Yet, in rural settings, little is known about who delivers colonoscopy and facilitators and barriers to colonoscopy access through screening completion. Methods: We conducted a qualitative study with providers in rural Oregon who worked in endoscopy centers or primary care clinics. Semistructured interviews, conducted in July and August, 2021, focused on clinician experiences providing colonoscopy to rural Medicaid patients, including workflows, barriers, and access. We used thematic analysis, through immersion crystallization, to analyze interview transcripts and develop emergent themes. Findings: We interviewed 19 providers. We found two categories of colonoscopy providers: primary care providers (PCPs) doing colonoscopy on their own patients (n = 9; 47%) and general surgeons providing colonoscopy to patients referred to their services (n = 10; 53%). Providers described barriers to colonoscopy at the provider, community, and patient levels and suggested patient supports could help overcome them. Providers found current colonoscopy capacity sufficient, but noted PCPs trained to perform colonoscopy would be key to continued accessibility. Finally, providers shared concerns about the shrinking number of PCP endoscopists, especially with anticipated increased screening demand related to the CRC screening guideline shift. Conclusions: These themes reflect opportunities to address multilevel barriers to improve access, colonoscopy capacity, and patient education approaches. Our results highlight that PCPs are an essential part of the workforce that provides colonoscopy in rural areas. [ABSTRACT FROM AUTHOR]

Abstract

Objectives: Fecal immunochemical testing (FIT) is an effective screening tool for colorectal cancer. If an FIT is abnormal, a follow-up colonoscopy is necessary to remove polyps or find cancers. We sought to develop a usable risk prediction model to identify patients unlikely to complete a colonoscopy following an abnormal FIT test. Methods: We recalibrated and then redeveloped a prediction model in federally qualified health centers (FQHCs), using a retrospective cohort of patients aged 50–75 with an abnormal FIT test and clinical data. Logistic and Cox regressions were used to recalibrate and then redevelop the model. Results: The initial risk model used data from eight FQHCs (26 clinics) including 1723 patients. When we applied the model to a single large FQHC (34 clinics, 884 eligible patients), the model did not recalibrate successfully (c-statistic dropped more than 0.05, from 0.66 to 0.61). The model was redeveloped in the same FQHC in a cohort of 1401 patients with a c-statistic of 0.65. Conclusions: The original model developed in a group of FQHCs did not adequately recalibrate in the single large FQHC. Health system, patient characteristics or data differences may have led to the inability to recalibrate the model. However, the redeveloped model provides an adequate model for the single FQHC.

38. COMMENTARY: Review: On-demand maintenance therapy with proton pump inhibitors is as effective as continuous therapy for nonerosive GERD.

Abstract

The author reflects upon the findings of a study showing the on-demand maintenance therapy to be more effective than the placebo, in the treatment of patients with gastroesophageal reflux disease (GERD). He supports the heterogeneous nature of the study and considers the evasion of meta-analysis, appropriate for the study's results. He suggests the implications of the results on the pharmaceutical industry. He also comments on the controversy over the categorical or spectrum nature of the GERD.
