A Mobile Phone-Based Sexual and Reproductive Health Intervention for Female Sex Workers in Kenya: Development and Qualitative Study

Costs and cost drivers of comprehensive sexual reproductive health services to female sex workers in Kenya

BACKGROUND

Comprehensive sexual reproductive health (SRH) programs for female sex workers (FSW) offering clinical, behavioural, and structural interventions have contributed to declining rates of HIV in this population. However, data on costs and cost drivers is needed to support programs and their donors to better allocate resources, make an investment case for continued funding, and to identify areas of improvement in program design and implementation. We aimed to estimate the annual per-FSW costs of comprehensive services for a standalone FSW program in Kenya.

METHODS

We implemented a top-bottom and activity-based costing study of comprehensive FSW services at two drop-in centres (DICs), Mtwapa and Kilifi town, in Kilifi County, Kenya. Service costs were obtained from routinely collected patient data during FSW scheduled and unscheduled visits using Kenyan Ministry of Health records. Costing data were from the program and organization's expenditure reports, cross checked against bank documents and supported by information from in-depth interviews. Data were collected retrospectively for the fiscal year 2019. We obtained approval from the AMREF Research Ethics Committee (AMREF-ESRC P862/2020).

RESULTS

In 2019, the unit cost of comprehensive services was 105.93 USD per FSW per year, roughly equivalent to 10,593 Kenya shillings. Costs were higher at Mtwapa DICs compared to Kilifi town DIC; 121.90 USD and 89.90 USD respectively. HIV counselling and testing cost 63.90 USD per person, PrEP was 34.20 USD and family planning was 9.93 USD. Of the total costs, staff salaries accounted for about 60%. Adjusted for inflation, costs in 2024 would be approximately 146.60.

CONCLUSION

Programs should strive to maximize the number of FSW served to benefit from economies of scale. Given that personnel costs contribute most to the unit costs, programs should consider alternative designs which reduce personnel and other costs.

Effectiveness of mHealth intervention on safe abortion knowledge and perceived barriers to safe abortion services among female sex workers in Vietnam

BACKGROUND

Mobile health (mHealth) has been used to promote sexual and reproductive health (SRH) education and services; however, little is known about the use of mHealth to improve safe abortion knowledge and access to safe abortion services among female sex workers (FSWs). This study evaluated the feasibility and effectiveness of iConnect intervention through changes in knowledge on safe abortion and changes in perceived barriers to safe abortion services among FSWs in Vietnam.

METHODS

iConnect mobile app was developed as an interactive platform to deliver safe abortion education and referral to safe abortion services through short messaging services (SMS) enhanced by tele-counseling for 512 FSWs in Hanoi, Vietnam. A pretest-posttest evaluation was conducted using questionnaire-based phone interviews administered to 251 participants at baseline and 3 months following the intervention. Non-parametric tests evaluated the change in abortion knowledge, behaviors, and perceived barriers to safe abortion.

RESULTS

There were significant improvements in the knowledge on safe abortion among the study participants. Specifically, FSWs' knowledge of correct gestational ages (≤22 weeks) for medical abortion increased from 78.9% at baseline to 96.8% (P=0.001). Knowledge of correct gestational ages for medical abortion at the private clinic increased from 45.3% to 63.1% (P=0.001). Knowledge on the consequences of unsafe abortion increased from 75.2% to 92.1% (P=0.001). In addition, perceived stigma and discrimination when seeking safe abortion decreased from 36.5% to 27.8% (P=0.036) and worry about the lack of confidentiality decreased from 23.3% to 15.5% (P=0.035).

CONCLUSIONS

The evaluation results showed the initial effectiveness of a mobile app-based intervention in improving access to safe abortion information and services among FSWs. A future study is needed to establish the efficacy of the intervention for scaling up in Vietnam and elsewhere.

Information and communications technology use to prevent and respond to sexual and gender-based violence in low- and middle-income countries: An evidence and gap map

BACKGROUND

The use of information and communications technologies (ICT) in low- and middle-income countries (LMIC) has increased significantly in the last several years, particularly in health, including related areas such as preventing and responding to sexual and gender-based violence (SGBV) against women and children. While the evidence for ICT effectiveness has grown significantly in the past 5 years in other aspects of health, it has not for effectiveness of using ICT for the prevention and response to SGBV against women and children in LMIC.

OBJECTIVES

The primary goal of this evidence and gap map (EGM) is to establish a baseline for the state of the evidence connected with the use of ICT for preventing and responding to SGBV against women and children in LMIC. Objectives that contribute to the achievement of this goal are: (1)identifying evidence of effectiveness for the use of ICT targeting the prevention of, and response to, SGBV against women and children in LMIC;(2)identifying key gaps in the available ICT for SGBV prevention and/or response evidence;(3)identifying research methodology issues reflected in the current evidence;(4)identifying any clusters of evidence in one or more ICT interventions suitable for systematic review;(5)identifying enabling factors associated with effective interventions using ICT for the prevention of, and response to, SGBV against women and children in LMIC; and(6)providing a structured and accessible guide to stakeholders for future investment into interventions and research using ICT for SGBV prevention and response in LMIC.

SEARCH METHODS

The date of the last search from which records were evaluated, and any studies identified were incorporated into the EGM was July 11, 2021. Twenty (20) databases were searched, and identified under "Methods."

SELECTION CRITERIA

We conducted systematic searches of multiple academic databases using search terms and criteria related to the use of ICT for prevention and/or response to SGBV against women and children. Although excluded, we did consider studies conducted in higher-income countries (HIC) only to provide context and contrast for the EGM discussion of the eligible studies from LMIC.

DATA COLLECTION AND ANALYSIS

The EGM search process included five phases: (1) initial search of academic databases conducted by two researchers simultaneously; (2) comparison of search results, and abstract screening by two researchers collaboratively; (3) second screening by reviewing full articles of the studies identified in the first screening by two reviewers independently; (4) comparison of results of second screening; resolution of discrepancies of screening results; and (5) data extraction and analysis.

MAIN RESULTS

The EGM includes 10 studies published in English of which 4 were systematic, literature or scoping reviews directly addressing some aspect of the use of ICT for SGBV prevention and/or response in women and girls. The six individual studies were, or are being, conducted in LMIC (a condition for eligibility). No eligible studies addressed children as a target group, although a number of the ineligible studies reported on the use of ICT for intermediate outcomes connected with violence against children (e.g., digital parenting). Yet, such studies did not explicitly attach those intermediate outcomes to SGBV prevention or response outcomes. Countries represented among the eligible individual studies include Cambodia, Kenya, Nepal Democratic Republic of Congo (DRC), and Lebanon. Of the 10 eligible studies (individual and reviews), most focused on intimate partner violence against women (IPV). Intervention areas among the eligible studies include safety planning using decision algorithms, educational and empowerment messaging regarding norms and attitudes towards gender-based violence (GBV), multi-media radio drama for social behavior change, the collection of survivor experience to inform SGBV/GBV services, and the collection of forensic evidence connected to the perpetration of SGBV. Thirty-one studies which otherwise would have been eligible for the evidence and gap map (EGM) were conducted in HIC (identified under "Excluded Reviews"). None of the eligible studies reported results related to effectiveness of using ICT in a control setting, for the primary prevention of SGBV as an outcome, but rather reported on outcomes such as usability, secondary and tertiary prevention, feasibility, access to services and other outcomes primarily relating to the development of the interventions. Two studies identified IPV prevention as a measurable outcome within their protocols, but one of these had not yet formally published results regarding primary prevention as an outcome. The other study, while reporting on the protocol (and steps to adapt the ICT application, previously reported as effective in HIC contexts to a specific LMIC context), has not yet as of the date of writing this EGM, published outcome results related to the reduction of IPV. Of the four reviews identified as eligible, two are better characterized as either a literature review or case study rather than as traditional systematic reviews reporting on impact outcomes with methodologically rigorous protocols.

AUTHORS' CONCLUSIONS

The evidence baseline for using ICT to prevent and/or respond to SGBV against women and children in LMIC is nascent. Promising areas for future study include: (1) how ICT can contribute changing gender and social norms related to SGBV and primary prevention; (2) mobile phone applications that promote safety and security; (3) mobile technology for the collection and analysis of survivors' experience with SGBV response services; and (4) digital tools that support the collection of forensic evidence for SGBV response and secondary prevention. Most striking is the paucity of eligible studies examining the use of ICT in connection with preventing or responding to SGBV against children. In light of the exponential increase in the use of ICT by children and adolescents, even in LMIC, greater attention should be given to examining how ICT can be used during adolescence to address gender norms that lead to SGBV. While there appears to be interest in using ICT for SGBV prevention and/or response in LMIC, other than several ad hoc studies, there is little evidence of if, and how effective these interventions are. Further inquiry should be made regarding if and how interventions proven effective in HIC can be adapted to LMIC contexts.

Effect of a mobile phone intervention for female sex workers on unintended pregnancy in Kenya (WHISPER or SHOUT): a cluster-randomised controlled trial

BACKGROUND

Female sex workers in low-income and middle-income countries face high risks of unintended pregnancy. We developed a 12-month, multifaceted short messaging service intervention (WHISPER) for female sex workers in Kenya who had the potential to become pregnant, to improve their contraceptive knowledge and behaviours. The aim of this study was to assess the effectiveness of the intervention to reduce the incidence of unintended pregnancy among sex workers in Kenya compared with an equal-attention control group receiving nutrition-focused messages (SHOUT).

METHODS

Our two-arm, cluster-randomised controlled trial was done in sex-work venues in two subcounties of Mombasa, Kenya (Kisauni and Changamwe). Participants, aged 16-34 years, not pregnant or planning pregnancy, able to read text messages in English, residing in the study area, and who had a personal mobile phone with one of two phone networks, were recruited from 93 randomly selected sex-work venues (clusters). Random cluster allocation (1:1) to the intervention or control group was concealed from participants and researchers until the intervention started. Both groups received text messages in English delivered two to three times per week for 12 months (137 messages in total), as well as additional on-demand messages. Message content in the intervention group focused on promotion of contraception, particularly long-acting reversible contraception and dual method contraceptive use; message content in the control group focused on promotion of nutritional knowledge and practices, including food safety, preparation, and purchasing. The primary endpoint, analysed in all participants who were randomly assigned and attended at least one follow-up visit, compared unintended pregnancy incidence between groups using discrete-time survival analysis at 6 and 12 months. This trial is registered with Australian New Zealand Clinical Trials Registry, ACTRN12616000852459, and is closed to new participants.

FINDINGS

Between Sept 14, 2016, and May 16, 2017, 1728 individuals were approached to take part in the study. Of these, 1155 were eligible for full screening, 1035 were screened, and 882 were eligible, enrolled, and randomly assigned (451 participants from 47 venues in the intervention group; 431 participants from 46 venues in the control group). 401 participants from the intervention group and 385 participants from the control group were included in the primary analysis. Incidence of unintended pregnancy was 15·5 per 100 person-years in the intervention group and 14·7 per 100 person-years in the control group (hazard ratio 0·98, 95% CI 0·69-1·39).

INTERPRETATION

The intervention had no measurable effect on unintended pregnancy incidence. Mobile health interventions, even when acceptable and rigorously designed, are unlikely to have a sufficient effect on behaviour among female sex workers to change pregnancy incidence when used in isolation.
