Factors associated with psychotherapy longevity among HIV-positive patients

In-home mental health treatment for individuals with HIV

Mental health problems are highly prevalent among individuals with HIV and are consistently associated with negative health outcomes. However, mental illness often remains untreated due to significant psychosocial and physical barriers to treatment participation. The Collaborative HIV/AIDS Mental Health Program (CHAMP) assessed the outcomes associated with providing 9 months of in-home mental health counseling for 40 individuals with HIV and a Major Axis I mental disorder. The evidence-based Illness Management and Recovery Model was adapted for use with HIV-positive individuals for the study using a community-based participatory research approach. Study participants were surveyed at baseline, 5 and 9 months to assess for changes in health outcomes. Thirty-five percent of study participants were female, 80% African American, 33% self-identified as MSM and the average participant age was 43. Forty percent of participants were on psychotropic medication at baseline. Participants had an average of 8 counseling visits (median 9). Statistically significant decreases in the global Brief Symptom Inventory (BSI) score and a number of BSI symptoms dimensions including anxiety, depression, obsessive compulsive, phobic anxiety and hostility were detected, indicating a reduction of psychiatric symptoms. Statistically significant improvement was also identified for the SF-12 mental health scale, adaptive coping, overall social support and emotional support. No differences in psychiatric outcomes were identified by gender, race/ethnicity, or sexual preference. Findings from the CHAMP Study suggest that the use of in-home mental health treatment may be beneficial in engaging and treating HIV-positive individuals with comorbid mental health disorders.

Impact of adherence counseling dose on antiretroviral adherence and HIV viral load among HIV-infected methadone maintained drug users

Adherence counseling can improve antiretroviral adherence and related health outcomes in HIV-infected individuals. However, little is known about how much counseling is necessary to achieve clinically significant effects. We investigated antiretroviral adherence and HIV viral load relative to the number of hours of adherence counseling received by 60 HIV-infected drug users participating in a trial of directly observed antiretroviral therapy delivered in methadone clinics. Our adherence counseling intervention combined motivational interviewing and cognitive-behavioral counseling, was designed to include six 30 minute individual counseling sessions with unlimited "booster" sessions, and was offered to all participants in the parent trial. We found that, among those who participated in adherence counseling, dose of counseling had a significant positive relationship with antiretroviral adherence measured after the conclusion of counseling. Specifically, a liner mixed-effects model revealed that each additional hour of counseling was significantly associated with a 20% increase in post-counseling adherence. However, the number of cumulative adherence counseling hours was not significantly associated with HIV viral load, also measured after the conclusion of counseling. Our findings suggest that more intensive adherence counseling interventions may have a greater impact on antiretroviral adherence than less intensive interventions; however, it remains unknown how much counseling is required to impact HIV viral load.

Improving access to mental health services via a clinic-wide mental health intervention in a Southeastern US infectious disease clinic

Stepleman, Hann, Santos, and House (2006) described a brief psychological consultation model, which aims to improve integration of mental health services into HIV primary care. This retrospective chart review sought to examine which patients in our adult Infectious Disease clinic were served by this model in a one-year period. Furthermore, we examined whether the patients who subsequently engage in mental health care differ demographically from the consult population. Results indicated that 26.1% (n=252) of the patients at our Infectious Disease clinic (n=963; 36% female, 75% racial minority) received a mental health consultation. We observed no statistically significant differences between the consult and clinic populations with respect to gender, age, or race. Moreover, 43.3% (n=109) of those patients served by the consult model received specialized psychiatric care. There were statistically significant racial differences between those patients who engaged specialty psychiatric care and those who did not after receiving a consultation (chi(2)(1)=16.65, p<0.001; 70% racial minority in consult vs. 47.7% racial minority in psychiatric care). While our in-clinic consultation service reached a representative population, we had less success recruiting this diverse patient population into traditional psychiatric care. Future efforts will need to examine how mental health consultation and traditional psychiatric services can best reduce barriers to engagement and retention in care.
