Pilot Study of a Mobile Health Approach to Reduce Barriers to Cervical Cancer Screening in Tanzania

Introduction:

Cervical cancer is the leading cause of cancer-related deaths in Tanzania. The age-adjusted incidence rate is estimated to be 54 cases per 100,000 (IARC, 2012) and 80% of Tanzanian women affected by cervical cancer will die due to advanced stage at diagnosis (Kahesa, et al., 2012). Visual Inspection of the cervix under Acetic Acid (VIA) is an effective alternative to the Pap smear, unavailable in most low-resource countries due to weak health systems (Palanuwong, 2007). Nurses typically receive 6 days of training before returning to their communities to provide VIA; however, they often face a total lack of oversight to ensure they are providing quality screening and cryotherapy. This lack of quality control has prevented a decline in cervical cancer morbidity and mortality despite significant investment and implementation of VIA programs.

The Kilimanjaro Cervical Cancer Screening Project (KCCP) is a pilot study of 1000 women that developed and tested a cervicography (taking a digital photo of the cervix) training method using a smartphone camera in the hands of nurses performing cervical cancer screening and receiving 'real time' mentorship through a closed user group of image transfer and guidance by cervicographers located elsewhere in Tanzania. A pilot study completed in February 2015 showed that this method provides safe and high quality screening and the method is moving to implementation and scale up within multiple VIA programs in late 2015 (Yeates et al., Manuscript in preparation). The KCCP continues to screen patients and this provides a significant opportunity to perform further research that will inform the scale-up program.

Measures to encourage increased uptake of cervical cancer screening in the region, and in many low-resource contexts are drastically needed to reduce the burden of cervical cancer in these contexts. The prevalence of screening in the Kilimanjaro is 6%(Cunningham et al, 2015), which is close to the WHO figure of 5% of women in developing countries having been screened in the last five years (World Health Organization, 1986). The largest perceived barriers to cervical cancer screening in the Kilimanjaro region were found to be a lack of knowledge that screening services were available and women anticipated that they would not be able to afford the costs associated with screening, including travel (Cunningham et al, 2015).
