Gay men’s awareness of HIV post-exposure prophylaxis
(PEP) significantly improved in Western Australia, following implementation of
a communications strategy, according to a study recently published in BMC Public Health. The study is of
interest as research on the impact of communication campaigns is
relatively rare.
In response to data showing low awareness of non-occupational
PEP in the gay community and prescription of PEP outside the guidelines, communications
were delivered from May 2005 onwards. The main elements were:
- a basic leaflet
and poster on PEP for distribution via gay venues, sexual health services and
partner organisations
- advertising in the Perth gay newspaper and on the
Gaydar website
- a 24-hour phoneline, staffed by nurses
- distribution of guidelines and related
communications to health professionals.
Gay and bisexual men’s awareness of PEP was measured
through the Perth Gay Community Periodic Surveys, conducted in 2002, 2004,
2006, 2008 and 2010. Whereas in the two surveys prior to the communication
strategy, only 17.2 and 23.4% of men were aware of PEP, this rose to 44.9% in
2006 and 54.9% in 2008.
However, awareness dropped in 2010 to 39.9%. The authors
note that the communication channels and materials have changed very little
since the campaign began. The recent results “suggest that a fresh approach
should be considered, which could include opportunities to engage recent trends
in social marketing, such as the use of social media”, they say.
Audit data also show an improvement in the proportion of
PEP prescriptions that meet the eligibility criteria of local guidelines. In
2002 to 2005, 61.2% of prescriptions met guidelines, rising to 90.0% in 2008 to
2010 (p = <.001). Whereas PEP had previously often been prescribed to people
with low-risk exposures, there has been a rise in the number of gay men taking
PEP.
The authors acknowledge that other factors, in addition to the communication strategy, may have contributed to these changes.
