The PharmFIT Study

Official title

Expanding Access to Colorectal Cancer Screening Through Community Pharmacies: The PharmFIT Study

Overview

This study will conduct a randomized controlled trial to assess the impact of a pharmacy-based FIT intervention, Pharmacy-based FIT (PharmFIT), on colorectal cancer screening (CRC) screening rates in primary care patients who are not up to date on CRC screening. Through collaboration with community partners in North Carolina and the Pacific Northwest region, 1) the impact will be evaluated, 2) the implementation will be assessed, and 3) the costs of the PharmFIT intervention cost will be estimated. Patients (n=1,200) will be individually randomized to a usual care arm or a PharmFIT arm and we will determine whether there are statistically significant differences in CRC screening rates. Concurrently, a mixed methods approach will be used to assess a range of preliminary implementation outcomes, identify outcome barriers and facilitators, and identify implementation strategies to support future research. Also, the cost of PharmFIT will be calculated, using collaborative process flow diagramming (PFD) to inform micro-costing and budget impact analysis. Supported by preliminary work from the investigators, demonstrating widespread acceptability, feasibility, and preliminary effectiveness of PharmFIT, the rationale to conduct this hybrid 1 effectiveness-implementation trial1 is to generate new knowledge about pharmacy-based interventions to effectively increase CRC screening uptake and implementation. The central hypothesis is that the PharmFIT intervention will increase screening uptake by improving access to, and opportunities for, this preventive service through the involvement of a multidisciplinary, multisite, team-based care approach to CRC screening.

Detailed description

The long-term goal of this study is to reduce CRC mortality by increasing access to CRC screening. The overall objective is to evaluate the effectiveness and implementation of a pharmacy-based FIT (PharmFIT) intervention. PharmFIT is a collaborative patient care service intervention that involves primary care clinics identifying active patients who are due for screening and referring them, outside of a medical visit, to community pharmacies to receive their CRC screening via FITs. The program consists of 1) Patient eligibility assessments and endorsement by the Primary Care Provider (PCP); 2) Counseling on FIT use and return by the pharmacists; 3) Reminders to complete screening by the pharmacy staff; 3) Test result communication by the pharmacists/PCPs; and 4) Patient navigation and care coordination for follow-up care by both pharmacists and PCPs.

Interventions

• Behavioral PharmFIT
  The PharmFIT intervention involves the following components: referral notice to patient, FIT ready notification, FIT ready reminders, FIT distribution, FIT completion reminders, negative and positive results notification, patient navigation support.

Primary outcome measures

• Service Penetration (Effectiveness) [Time frame: 6-months post randomization]
• Appropriateness of the PharmFIT intervention [Time frame: 6-months post enrollment]
• Acceptability of the PharmFIT intervention [Time frame: 6-months post enrollment]
• Feasibility of the PharmFIT intervention [Time frame: 6-months post enrollment]
• Fidelity to the PharmFIT intervention [Time frame: Baseline, 6-months post enrollment]
• Cost of the PharmFIT intervention [Time frame: Through study completion, up to 12 months after PharmFIT intervention implementation]

Secondary outcome measures (3)

• Reach [Time frame: 6-months post enrollment]
• Timely FIT completion [Time frame: 60 days post FIT receipt]
• Timely follow-up colonoscopy [Time frame: 6-months post enrollment]
