"Our Choice" improves use of safer conception methods among HIV serodiscordant couples in Uganda: a cluster randomized controlled trial evaluating two implementation approaches

Background

Safer conception counseling (SCC) to promote the use of safer conception methods (SCM) is not yet part of routine family planning or HIV care. Guidelines for the use of SCM have been published, but to date there are no published controlled evaluations of SCC. Furthermore, it is unknown whether standard methods commonly used in resource constrained settings to integrate new services would be sufficient, or if enhanced training and supervision would result in a more efficacious approach to implementing SCC.

Methods

In a hybrid, cluster randomized controlled trial, six HIV clinics were randomly assigned to implement the SCC intervention Our Choice using either a high (SCC1) or low intensity (SCC2) approach (differentiated by amount of training and supervision), or existing family planning services (usual care). Three hundred eighty-nine HIV clients considering childbearing with an HIV-negative partner enrolled. The primary outcome was self-reported use of appropriate reproductive method (SCM if trying to conceive; modern contraceptives if not) over 12 months or until pregnancy.

Results

The combined intervention groups used appropriate reproductive methods more than usual care [20.8% vs. 6.9%; adjusted OR (95% CI)=10.63 (2.79, 40.49)], and SCC1 reported a higher rate than SCC2 [27.1% vs. 14.6%; OR (95% CI)=4.50 (1.44, 14.01)]. Among those trying to conceive, the intervention arms reported greater accurate use of SCM compared to usual care [24.1% vs. 0%; OR (95% CI)=91.84 (4.94, 1709.0)], and SCC1 performed better than SCC2 [34.6% vs. 11.5%; OR (95% CI)=6.43 (1.90, 21.73)]. The arms did not vary on modern contraception use among those not trying to conceive. A cost of $631 per person was estimated to obtain accurate use of SCM in SCC1, compared to $1014 in SCC2.

Conclusions

More intensive provider training and more frequent supervision leads to greater adoption of complex SCM behaviors and is more cost-effective than the standard low intensity implementation approach.

Study protocol of "Our Choice": a randomized controlled trial of the integration of safer conception counseling to transform HIV family planning services in Uganda

BACKGROUND

About 40% of HIV-positive women in sub-Saharan Africa become pregnant post-diagnosis. Despite about half of their pregnancies being planned, safer conception methods (SCM) are underutilized among serodiscordant couples, partially due to the fact that safer conception counseling (SCC) has not been integrated into routine HIV family planning (FP) services.

METHODS

Our Choice is a comprehensive FP intervention that promotes unbiased childbearing consultations to ensure clients receive SCC or contraception services to achieve their desired reproductive goals. The intervention is theoretically grounded and has demonstrated preliminarily feasibility and acceptance through pilot testing. This three-arm cluster randomized controlled trial compares two implementation strategies for integrating Our Choice into routine FP services vs. usual care. Six sites in Uganda will be randomized to receive either (1) Our Choice intervention with enhanced training and supervision provided by study staff (SCC1), (2) Our Choice intervention implemented by the Ministry of Health's standard approach to disseminating new services (SCC2), or (3) existing FP services (usual care). Our Choice and usual care FP services will be implemented simultaneously over a 30-month period. Sixty clients in serodiscordant relationships who express childbearing desires will be enrolled by a study coordinator at each site (n = 360) and followed for 12 months or post-pregnancy (once, if applicable). Analysis will compare intervention arms (SCC1 and SCC2) to usual care and then to each other (SCC1 vs. SCC2) on the primary outcome of correct use of either SCM (if trying to conceive) or dual contraception (if pregnancy is not desired). Secondary outcomes (i.e., pregnancy, use of prevention of mother-to-child transmission services, condom use, and partner seroconversion) and cost-effectiveness will also be examined.

DISCUSSION

Findings will provide critical information about the success of implementation models of varying intensity for integrating SCC into FP, thereby informing policy and resource allocation within and beyond Uganda.

Safer Conception Methods and Counseling: Psychometric Evaluation of New Measures of Attitudes and Beliefs Among HIV Clients and Providers

With data from 400 HIV clients with fertility intentions and 57 HIV providers in Uganda, we evaluated the psychometrics of new client and provider scales measuring constructs related to safer conception methods (SCM) and safer conception counselling (SCC). Several forms of validity (i.e., content, face, and construct validity) were examined using standard methods including exploratory and confirmatory factor analysis. Internal consistency was established using Cronbach's alpha correlation coefficient. The final scales consisted of measures of attitudes towards use of SCM and delivery of SCC, including measures of self-efficacy and motivation to use SCM, and perceived community stigma towards childbearing. Most client and all provider measures had moderate to high internal consistency (alphas 0.60-0.94), most had convergent validity (associations with other SCM or SCC-related measures), and client measures had divergent validity (poor associations with depression). These findings establish preliminary psychometric properties of these scales and should facilitate future studies of SCM and SCC.
