One randomised controlled trial (RCT) comparing patient versus provider referral and eight intervention evaluation studies were included in the review (n=3,437 cases; n=11,717 elicited partners). Sample sizes ranged between 42 and 1,379 for cases and between 135 and 8,633 for elicited partners.
Six studies reported a mean of 20 per cent of individuals (range 14 to 26 per cent) as newly diagnosed with HIV. This translated into a one to eight per cent proportion of all partners identified by cases.
Eight studies reported that a mean of 76 per cent (range 44 to 89 per cent) of partners were notified. Six studies reported that 63 per cent (range 42 to 97%) of notified individuals were tested.
Two direct comparison studies reported substantial differences in notification rates for contract referral (34 and 85 per cent) and reported patient referral as seven to 57 per cent notified.
Secondary outcomes were reported in the review, but only by studies that did not meet the inclusion criteria.
