Comparison of uptake rates and anxiety among women offered HIV testing through different approaches in the same hospital's antenatal clinic
| Approach | Time period | No of women having test/No of women attending clinic (% uptake) | Scaled mean anxiety¶ |
|---|---|---|---|
| Control* | May 1996 to Feb 1997 | 55/994 (6) | 36.8 (10.8) |
| Opt-in† | May 1996 to Feb 1997 | 707/2030 (35)§ | 36.4 (10.9) |
| Routine voluntary‡ | Feb to May 1998 | 816/924 (88) | 33.2 (10.6) |
| Significance | χ2=1413.6, df=2, P<0.0001 | F (2, 3448)=32.3, P<0.0001 |
↵* Test available on request only.
↵†Information given about testing and woman asked to choose whether she wanted test.
↵‡Information given about testing, but with testing presented as part of routine testing of blood and women given the opportunity to decline the test.
↵§Combined result for four different levels of an opt-in approach, which did not result in significantly different uptake rates.3
↵¶ Scores out of 24 have been scaled with a denominator of 80 to be comparable to the original 20 item anxiety scale used in previous study.3
