Background Integration of HIV treatment with other primary care services has been argued to potentially improve effectiveness, efficiency and equity. However, outside the field of reproductive health, there is limited empirical evidence regarding the scope or depth of integrated HIV programmes or their relative benefits. Moreover, the body of work describing operational models of integrated service-delivery in context remains thin. Between 2008 and 2011, the Lusaka District Health Management Team piloted and scaled-up a model of integrated HIV and general outpatient department (OPD) services in 12 primary health care clinics. This paper examines the effect of the integrated model on the organization of clinic services, and explores service providers’ perceptions of the integrated model.Methods We used a mixed methods approach incorporating facility surveys and key informant interviews with clinic managers and district officials. On-site facility surveys were carried out in 12 integrated facilities to collect data on the scope of integrated services, and 15 semi-structured interviews were carried out with 12 clinic managers and three district officials to explore strengths and weaknesses of the model. Quantitative and qualitative data were triangulated to inform overall analysis.Findings Implementation of the integrated model substantially changed the organization of service delivery across a range of clinic systems. Organizational and managerial advantages were identified, including more efficient use of staff time and clinic space, improved teamwork and accountability, and more equitable delivery of care to HIV and non-HIV patients. However, integration did not solve ongoing human resource shortages or inadequate infrastructure, which limited the efficacy of the model and were perceived to undermine service delivery.Conclusion While resource and allocative efficiencies are associated with this model of integration, a more important finding was the model’s demonstrated potential for strengthening organizational culture and staff relationships, in turn facilitating more collaborative and motivated service delivery in chronically under-resourced primary healthcare clinics.

IntroductionBuilding on earlier works demonstrating the effectiveness and acceptability of provider-initiated counselling and testing (PITC) services in integrated outpatient departments of urban primary healthcare clinics (PHCs), this study seeks to understand the relative utility of PITC services for identifying clients with early-stage HIV-related disease compared to traditional voluntary testing and counselling (VCT) services. We additionally seek to determine whether there are any significant differences in the clinical and demographic profile of PITC and VCT clients.MethodsRoutinely collected, de-identified data were collated from two cohorts of HIV-positive patients referred for HIV treatment, either from PITC or VCT in seven urban-integrated PHCs. Univariate and multivariate analyses were conducted to compare the two cohorts across demographic and clinical characteristics at enrolment.ResultsForty-five per cent of clients diagnosed via PITC had CD4<200, and more than 70% (i.e. two thirds) had CD4<350 at enrolment, with significantly lower CD4 counts than that of VCT clients (p<0.001). PITC clients were more likely to be male (p=0.0005) and less likely to have secondary or tertiary education (p<0.0001). Among those who were initiated on antiretroviral therapy (ART), PITC clients had lower odds of initiating treatment within four weeks of enrolment into HIV care (adjusted odds ratio, or AOR: 0.86; 95% confidence interval, or CI: 0.75–0.99; p=0.035) and significantly lower odds of retention in care at six months (AOR: 0.84; CI: 0.77–0.99; p=0.004).ConclusionsIn Lusaka, Zambia, large numbers of individuals with late-stage HIV are being incidentally diagnosed in outpatient settings. Our findings suggest that PITC in this setting does not facilitate more timely diagnosis and referral to care but rather act as a “safety net” for individuals who are unwilling or unable to seek testing independently. Further work is needed to document the way provision of clinic-based services can be strengthened and linked to community-based interventions and to address socio-cultural norms and socio-economic status that underpin healthcare-seeking behaviour.

Background: Previous operational research studies have demonstrated the feasibility of large-scale public sector ART programs in resource-limited settings. However, organizational and structural determinants of quality of care have not been studied.
