Study summary

Investigators will test the effectiveness of adaptive strategies on timely adoption of cervical cancer treatment in Botswana using a pragmatic trial design.

Read the detailed description

Investigators will test the effectiveness of adaptive strategies on timely adoption of cervical cancer treatment in Botswana using a hybrid (type III) and pragmatic Sequential Multiple Assignment Randomized Trial (SMART) design. The adaptive strategies are designed to target patient- and system-level determinants identified in preliminary data, including delayed communication of results, individual and structural barriers to accessing treatment, and suboptimal care coordination between referring and cancer treatment clinics. The strategies draw upon key principles in behavioral economics and are supported by systematic evidence of the effectiveness of nudge strategies in preventive, HIV, and cancer care. The overarching rationale for the study is that enhancing coordination, communication, and navigation through centralized outreach and nudge strategies will increase timely treatment adoption and be scalable and sustainable in the long-term.

Study arms

  • Experimental
    Stage 1 Clinic Outreach + Stage 2 Low Touch

    All participants receive direct clinic outreach to communicate readiness of results (stage 1). Participants who do not attend the clinic by 30 days (non-responders) will receive asynchronous text message reminders using framed messaging (stage 2).

    Behavioral: Clinic Outreach · Behavioral: Low-Touch Strategy

  • Experimental
    Stage 1 Clinic Outreach + Stage 2 High Touch

    All participants receive direct clinic outreach to communicate readiness of results (stage 1). Participants who do not attend the clinic by 30 days (non-responders) will receive asynchronous text message reminders using framed messaging in combination with synchronous patient navigation (stage 2).

    Behavioral: Clinic Outreach · Behavioral: High-Touch Strategy

  • Experimental
    Stage 1 Enhanced Outreach + Stage 2 Low-Touch

    All participants receive direct clinic outreach plus enhanced outreach to communicate readiness of results (stage 1). Participants who do not attend the clinic by 30 days (non-responders) will receive asynchronous text message reminders using framed messaging (stage 2).

    Behavioral: Enhanced Outreach · Behavioral: Low-Touch Strategy

  • Experimental
    Stage 1 Enhanced Outreach + Stage 2 High-Touch

    All participants receive direct clinic outreach plus enhanced outreach to communicate readiness of results (stage 1). Participants who do not attend the clinic by 30 days (non-responders) will receive asynchronous text message reminders using framed messaging in combination with synchronous patient navigation.

    Behavioral: Enhanced Outreach · Behavioral: High-Touch Strategy

Interventions

  • BehavioralClinic Outreach

    A member of the pathology team will contact the referring clinic to communicate the readiness of results.

  • BehavioralEnhanced Outreach

    A member of the pathology team will contact both the referring clinic and the patient directly to communicate the readiness of results.

  • BehavioralLow-Touch Strategy

    Patient will be sent asynchronous text messaging reminders related to the importance of timely care using framed messaging.

  • BehavioralHigh-Touch Strategy

    Patient will be sent asynchronous text messaging reminders related to the importance of timely care using framed messaging in combination with synchronous telephone-based patient navigation.

What researchers measure

Primary outcomes

  1. Adoption

    Defined as the initiation of cervical cancer treatment within 90 days of randomization.

    Time frame: Within 90 days of randomization

Secondary outcomes

  1. Fidelity

    Defined as completion of evidence-based cancer treatment according to international guidelines and measured using medical record data.

    Time frame: 12 months after randomization

  2. Reach: First Appointment

    Defined by the proportion of patients who complete an initial treatment visit divided by those randomized

    Time frame: 12 months after randomization

  3. Reach: First Stage

    Defined by the proportion of patients who complete an enhanced outreach phone call divided by those contacted.

    Time frame: 12 months after randomization

  4. Reach: Second Stage

    Defined by the proportion of patients who complete a patient navigation phone call (high touch strategy) divided by those contacted.

    Time frame: 12 months after randomization

  5. Reach: Results

    Defined by the proportion of patients with confirmation of results received divided by those randomized.

    Time frame: 12 months after randomization

Other outcomes

  1. Clinical Outcomes: Treatment

    Defined by the stage at diagnosis, type of cancer treatment the patient received (e.g., chemoradiation, surgery) measured using medical record data.

    Time frame: 12 months after randomization

  2. Clinical Outcomes: Survival

    Defined as overall survival at one year after randomization measured using medical record data.

    Time frame: 12 months after randomization
