Several interventions have been shown to improve linkage to care, such as point-of-care CD4 count directly after a positive HIV test, immediate start of cotrimoxazole prophylaxis, incentives such as food-assistance, extended post-test counselling during home-visits, or community-workers accompaniment. However, controlled studies testing programmatic intervention packages for improving linkage to care are still largely lacking (Okeke 2014; Govindasamy 2014). Furthermore, it must be noted that interventions, such as patient-accompaniment or food support are resource intensive and may work in small NGO-driven projects, but are not sustainable on a larger scale (Posse 2013). In a systematic review addressing barriers for linkage to care, transport cost and distance were the most frequently cited factors for patients not enrolling in care after a positive HIV test (Govindasamy 2012).
