Study summary

This study evaluates the effect of the SMS intervention 'Connected2Care' on the attendance rate to cervical cancer screening follow-up appointments.

Read the detailed description

Connected2Care is a non-blinded, multicentre, parallel-group, randomised controlled trial. Tanzanian Women testing positive to HR HPV at inclusion are randomly assigned in an allocation ratio of 1:1 to the SMS intervention or the control group (standard care). In a period of 10 months, the intervention group will receive 15 one-directional health educative text messages and SMS-reminders for their appointment. The total sample size will be 700 with 350 women in each study arm. Primary outcome is attendance rate for follow-up. Secondary objectives are cost-effectiveness measured through incremental ratios and knowledge of cervical cancer by a 16-item true/false scale questionnaire at baseline and follow-up.

Study arms

  • Experimental
    Connected to Care

    The SMS intervention will consist of 15 text messages that will be sent to the intervention group over a period of 10 months. There will be two types of text messages: (1) educational text messages; and (2) SMS reminders for the follow-up appointment.

    Behavioral: Connected to Care

  • No intervention
    Control

    The control group will receive standard care, which is a follow-up appointment at 14 months written on an appointment card.

Interventions

  • BehavioralConnected to Care

    10 health educative SMSs' sent once a month 5 SMS-reminders for follow-up appointment sent on days -14, -7, -1 pre- follow-up appointment, and +1, +7 post follow-up appointment

What researchers measure

Primary outcomes

  1. Effect of SMS intervention on attendance rate to follow-up screening appointment

    The effect measure of the intervention is the 14-month follow-up attendance rate for HPV positive women. The number of women in the intervention group that attend follow-up screening will be compared to the the number of women that attend follow-up screening in the control group.

    Time frame: up to 14 months

Secondary outcomes

  1. Acceptability of text message intervention

    6-point Likert scale (1: I do not like it at all - 6: I like it very much)

    Time frame: Baseline + 2 years Follow-up (likert scale)

  2. Acceptability of text message intervention

    Qualitative interviews. Open-ended

    Time frame: 2 years

Other outcomes

  1. Cost-effectiveness of intervention

    Incremental cost-effectiveness ratio

    Time frame: Baseline + 14 months

  2. Knowledge of cervical cancer and screening

    16 item true-false questionaire

    Time frame: Baselie + 14 months
