Use of SMSs to Improve Attendance to Cervical Cancer Follow-up Screening

Acceptability of text messages and knowledge change for cervical cancer screening: a Tanzanian mixed methods study

ObjectivesTo investigate the acceptability of a text message intervention and evaluate if text messages could increase knowledge of cervical cancer and screening.DesignThis study was a substudy of a randomised controlled trial that used a mixed methods research design combining a quantitative questionnaire dataset and qualitative interview data. A before and after assessment was made of questionnaire responses. Acceptability was measured on a 6-point Likert scale and knowledge was measured through 16 binary true/false knowledge questions concerning cervical cancer and screening. Qualitative data were coded using a combined inductive–deductive approach.SettingOcean Road Cancer Institute in Dar es Salaam as well as Kilimanjaro Christian Medical Center and Mawenzi Regional hospital in the Kilimanjaro Region in Tanzania.ParticipantsHuman papillomavirus (HPV) positive women who had been randomised to the intervention group and received educative and reminder messages. Qualitative interviews were conducted with a subgroup of women in the intervention group.Interventions15 one-way educative and reminder text messages.ResultsA total of 115 women in the intervention group responded to both the baseline and follow-up questionnaire. Overall, women found it highly acceptable to receive text messages, and there was a trend towards acceptability rising between baseline and follow-up (mean: 0.22; 95% CI 0.00 to 0.44; p=0.05; t-statics=1.96). A significant increase in acceptability was found among the lowest educated and those who had not previously been screened. The qualitative interviews showed that the underlying reasons for the high acceptability rate were that the women felt someone cared for them and that the text messages were for their own benefits. The text messages did not improve the women’s knowledge on cervical cancer and screening.ConclusionsEducative and reminder text messages are highly acceptable among HPV-positive Tanzanian women; however, they do not increase the women’s knowledge of cervical cancer and screening.Trial registration numberclingov (NCT02509702).

Effectiveness of One-Way Text Messaging on Attendance to Follow-Up Cervical Cancer Screening Among Human Papillomavirus–Positive Tanzanian Women (Connected2Care): Parallel-Group Randomized Controlled Trial

Background Rapid human papillomavirus (HPV) DNA testing is an emerging cervical cancer screening strategy in resource-limited countries, yet it requires follow-up of women who test HPV positive. Objective This study aimed to determine if one-way text messages improved attendance to a 14-month follow-up cervical cancer screening among HPV-positive women. Methods This multicenter, parallel-group randomized controlled trial was conducted at 3 hospitals in Tanzania. Eligible participants were aged between 25 and 60 years, had tested positive to a rapid HPV test during a patient-initiated screening, had been informed of their HPV result, and had a private mobile phone with a valid number. Participants were randomly assigned in a 1:1 ratio to the intervention or control group through an incorporated algorithm in the text message system. The intervention group received one-way text messages, and the control group received no text messages. The primary outcome was attendance at a 14-month health provider-initiated follow-up screening. Participants were not blinded, but outcome assessors were. The analysis was based on intention to treat. Results Between August 2015 and July 2017, 4080 women were screened for cervical cancer, of which 705 were included in this trial—358 women were allocated to the intervention group, and 347 women were allocated to the control group. Moreover, 16 women were excluded before the analysis because they developed cervical cancer or died (8 from each group). In the intervention group, 24.0% (84/350) women attended their follow-up screening, and in the control group, 23.8% (80/335) women attended their follow-up screening (risk ratio 1.02, 95% CI 0.79-1.33). Conclusions Attendance to a health provider-initiated follow-up cervical cancer screening among HPV-positive women was strikingly low, and one-way text messages did not improve the attendance rate. Implementation of rapid HPV testing as a primary screening method at the clinic level entails the challenge of ensuring a proper follow-up of women.
