OBJECTIVE

Pain medicine agreements are frequently recommended for use with high-risk patients on chronic opioid therapy. We assessed how consistently pain medicine agreements were used and whether patients were aware that they had signed a pain medicine agreement in a sample of HIV-infected adults prescribed chronic opioid treatment.

DESIGN

We recruited patients from a longitudinal cohort of community-based HIV-infected adults and recruited the patients' primary care providers (PCPs). The patients completed in-person interviews and PCPs completed mail-based questionnaires about the patients' use of pain medicine agreements. Among patients prescribed chronic opioid therapy, we analyzed the prevalence of pain medicine agreement use, patient factors associated with their use, and agreement between patient and clinician reports of pain agreements.

RESULTS

We had 84 patient-clinician dyads, representing 38 PCPs. A total of 72.8% of patients fit the diagnostic criteria for a lifetime substance use disorder. PCPs reported using pain medicine agreements with 42.9% of patients. Patients with pain medicine agreements were more likely to be smokers (91.7% vs 58.3%; P = 0.001) and had higher mean scores on the Screener and Opioid Assessment for Patients with Pain (µ = 26.0 [standard deviation, SD] = 9.7) vs µ = 19.5 [SD = 9.3]; P = 0.003). Patients reported having a pain medicine agreement with a sensitivity of 61.1% and a specificity of 64.6%.

CONCLUSIONS

In a high-risk sample, clinicians were using agreements at a low rate, but were more likely to use them with patients at highest risk of misuse. Patients exhibited low awareness of whether they signed a pain medicine agreement.

Despite the increased frequency of recurrent pneumonia in HIV-infected patients and recent studies linking the airway bacterial community (microbiota) to acute and chronic respiratory infection, little is known of the oral and airway microbiota that exist in these individuals and their propensity to harbor pathogens despite antimicrobial treatment for acute pneumonia. This pilot study compared paired samples of the oral and airway microbiota from 15 hospitalized HIV-infected patients receiving antimicrobial treatment for acute pneumonia. Total DNA was extracted, bacterial burden was assessed by quantitative PCR, and amplified 16S rRNA was profiled for microbiome composition using a phylogenetic microarray (16S rRNA PhyloChip). Though the bacterial burden of the airway was significantly lower than that of the oral cavity, microbiota in both niches were comparably diverse. However, oral and airway microbiota exhibited niche specificity. Oral microbiota were characterized by significantly increased relative abundance of multiple species associated with the mouth, including members of the Bacteroides, Firmicutes, and TM7 phyla, while airway microbiota were primarily characterized by a relative expansion of the Proteobacteria. Twenty-two taxa were detected in both niches, including Streptococcus bovis and Chryseobacterium species, pathogens associated with HIV-infected populations. In addition, we compared the airway microbiota of five of these patients to those of five non-HIV-infected pneumonia patients from a previous study. Compared to the control population, HIV-infected patients exhibited relative increased abundance of a large number of phylogenetically distinct taxa, which included several known or suspected pathogenic organisms, suggesting that recurrent pneumonia in HIV-infected populations may be related to the presence of these species.
