Conclusion:
Family planning interventions such as CHARM2, which utilize person-centered shared decision-making contraceptive counseling approaches improve women’s perceived quality of care. Effects on quality of care mediate observed effects of the intervention on contraceptive use.

Implications:
Contraceptive interventions should focus on improving person-centered outcomes, such as quality of care, rather than contraceptive use targets. By focusing on improving person-centered care, interventions will improve contraceptive use among those who desire a method while meeting the holistic reproductive health needs...

Background
DSD, viral suppression
Of the 8 million people in South Africa living with HIV, 74% of persons living with HIV are on antiretroviral therapy (ART) and 65% are virally suppressed. Detectable viral load results in HIV-associated morbidity and mortality and HIV transmission. Patient barriers to care, such as missed wages, transport costs, and l...
