The role of SEAD project intervention in viral suppression of HIV/AIDS patients with follow-up and adherence barriers

摘要

Purpose of studyIrregular FUP/ADH were associated with virologic failure [1] leading to an increase in mortality [2]. SEAD was a multidimensional intervention project, designed from the patient's perspective, to specifically attend patients with poor FUP/ ADH in an HIV/AIDS outpatient clinic.MethodsFrom Jan 2006 to May 2010, patients with poor FUP/ADH were offered SEAD inclusion, all were evaluated by a nurse or a psychologist (adherence collaborators) who assessed all the reasons and barriers precluding a correct FUP/ADH. For each identified problem, different interventions were planned, using our own resources or coordinating others. Follow-up was censored in Nov 2011. Univariate and multivariable models were performed to evaluate the influence of SEAD intervention in virological suppression (HIV-ARN 90% 29.3%; median CD4 cell count 333 [164–536] cells/mL and HIV-RNA 50% of planned interventions. After a median follow-up of 3.9 (3.27–4.43) years 218 patients received 8 (3–12) interventions/year, 95% evaluation interview and 30% psychological counselling (3 sessions/year [2–5]). Virological suppression was achieved by 67% of patients. In logistic regression analysis an intervention higher than 50% of planned HR 0.220 [IC 95% (0.112–0.44)] and receiving psychological counselling HR 0.44 [IC 95% (0.20–0.97)] were independent predictors of virological suppression whereas alcohol 3.11 (95% CI 1.24–7.80) and severe biopsychosocial problems HR 2.39 (95% CI 1.134–5.040) were associated with worse virological response, after adjusting for age, alcohol or cocaine abuse, degree of adherence, baseline virological suppression, median follow–up, intravenous acquisition of HIV, and family support.ConclusionsGeneral and psychological SEAD intervention resulted in higher virological suppression in patients with severe follow-up and adherence barriers.
