Task shifting to nurses and HIV counsellorsIn common with many rural HIV health services inSouthern Africa, the service demands outstripped thehuman resource capacity. When the pre-ART servicestarted in February 2009, the staff for the HIV serviceconsisted of two doctors, two nurses, three HIV coun-sellors and one pharmacist to attend to an average of2000 patients each month. Previously assessment forART initiation was doctor-led. The new pre-ART servicewas nurse-led. Nurses provided the triage for patientsentering the pre-ART system and most of the clinicalassessment for ART initiation.
