Assessment of adherence within AIDS clinical trials is a critical comp
onent of the successful evaluation of therapeutic outcomes. Poor medic
ation adherence can result in the misinterpretation of clinical trial
data. Research on factors affecting adherence in AIDS clinical trials
has been scarce, and few investigations have evaluated strategies for
enhancing patient participation. One reason may be the absence of a co
nceptual framework to guide research. Consistent with previous researc
h on medical adherence, we propose a framework whereby factors affecti
ng adherence in AIDS clinical trials can be categorized as characteris
tics of the: (a) individual, (b) treatment regimen, (c) patient-provid
er relationship, (d) clinical setting, and (e) disease. This framework
is used as a heuristic for reviewing studies that examine factors aff
ecting adherence in AIDS clinical trials. Suggestions for future resea
rch and clinical intervention are provided. These efforts are timely b
ecause adherence is now the center of attention in discourse about the
efficacy of the new class of protease inhibitor drugs; non-adherence
has been linked to viral resistance and drug failure. Efforts to ident
ify factors that influence adherence to AIDS clinical trials can infor
m future attempts to improve adherence and retention. Better adherence
protects the scientific integrity of AIDS clinical trials, promoting
more efficient and accurate evaluations of therapeutic value. Accelera
ted access to new treatments may follow, ultimately enhancing patient
care. (C) 1997 Elsevier Science Inc.
