Factors that affect HIV testing and counseling services among heterosexuals in Canada and the United Kingdom: An integrated review

ObjectiveTo examine factors that affect the utilization of HIV testing and counseling (HTC) services among heterosexual populations in Canada and the UK.MethodsWe conducted an integrated review of published and unpublished literature (1996-September 2010) using Scopus, OVID-EMBASE, CSA illumina, CINHAL, PROQuest, Web of Science, and Google.ResultsTwenty-seven studies met the inclusion criteria. We identified and categorized the key factors into three broad categories depending on their source. Personal-related factors included socio-demographic characteristics, risk perception, illness, HIV-related stigma, level of HIV and testing knowledge, and culture. Provider-related factors included provider-recommended HIV testing, provision of culturally and linguistically appropriate services, and doctor-patient relationship. System-related factors included integrating HIV testing with other health care services, anonymity of testing services, suitability of testing venues, technical aspects of HIV testing, and funding for immigrant health services.ConclusionThe findings from our review indicate that HTC behaviors of heterosexuals in the Canada and the UK are likely influenced by several unchangeable (socio-demographic characteristics) and amenable factors. There is need to step-up research to confirm whether these associations are causal using stronger research designs.Practical implicationWe have made several recommendations that could be used to improve existing services in Canada.
