Patient and health facility attributes associated with retention and virologic suppression in private for-profit health facilities in Nigeria.

BACKGROUND

In Nigeria, private for-profit health facilities present an opportunity to achieve the UNAIDS 95-95-95 HIV targets because of their reach and patronage. However, little is known about determinants of outcomes in these facilities. This study describes patient outcomes and the patient and health facility characteristics associated with these outcomes in adults receiving HIV treatment in private facilities in the Federal Capital Territory (FCT), Benue and Nasarawa states in north-central Nigeria.

METHODS

A retrospective longitudinal analysis of program data collected between 2013 and 2019 was done. Patient attributes and outcomes were compared across the two states and FCT. Incidence rates were determined for all cause exit, mortality and loss to follow up (LTFU). Cox proportional hazard models were used to identify associations between patient and facility attributes and these outcomes. Bivariate and multivariate logistic regression models were used to determine the factors associated with viral suppression among the study participants.

RESULTS

Of the 22,010 study subjects, 42.7%, 22.2% and 35.1%, respectively, were in Benue, FCT and Nasarawa. Almost a third (31.8%) had received antiretroviral treatment (ART) for less than a year at censoring. Incidence rates for all-cause exit, mortality and loss to follow up (LTFU) were 17.2 (95% CI 16.8, 17.5), 2.1 (95% CI 2.0, 2.2), and 11.2 (95% CI 10.8, 11.8) per 100 person years respectively. Males had higher risks of death (HR = 1.47, 95% CI 1.25-1.73), and LTFU (HR = 1.08, 95% CI 1.00-1.16). Age at ART start showed a dose-response association with both mortality and LTFU. Care at model facilities (OR = 2.16, p < 0.001), Zidovudine (AZT)-based regimens (OR = 2.00, p < 0.001), and lowest quartile baseline CD4 + count (OR = 2.40, p < 0.001) were associated with regimen switch. 75.6% of subjects were viral suppressed. Male gender (OR = 0.84, p = 0.025); AZT-based regimen (OR = 0.72, p < 0.001), age in the bottom quartile (OR = 0.71, p = 0.002) were associated with virally suppression.

CONCLUSION

Private for-profit facilities are a major provider of HIV and other health services in Nigeria. With appropriate technical support and engagement, they can help accelerate efforts to achieve epidemic control of HIV in Nigeria, and contribute to achievement of UNAIDS 95-95-95 target by 2030.
