Adherence to highly active antiretroviral therapy in Spain. A meta-analysis.

Objectives: To estimate the percentage of adherence to highly-active antiretroviral therapy (HAART) in Spanish observational studies and to identify the variables associated with adherence.

Methods: Seven electronic databases were used to locate the studies. Six inclusion criteria were established.

Adherence to highly active antiretroviral therapy (HAART): a meta-analysis.

This meta-analysis synthesizes eighty-four observational studies, conducted across twenty countries, to determine the mean proportion of people who reported ≥90% adherence to prescribed highly active antiretroviral therapy (HAART) and to identify the factors associated with high levels of adherence. Eight electronic databases were searched to locate all relevant studies available by January 2010, which were then coded for sample characteristics and adherence levels. The average rate of reporting ≥90% adherent HAART adherence is 62%.
