Missed Visits and Mortality among Patients Establishing Initial Outpatient HIV Treatment
2009
Background.Dramatic increases in the number of patients requiring linkage to treatment for human immunodeficiency virus (HIV) infection are anticipated in response to updated Centers for Disease Control and Prevention HIV testing recommendations that advocate routine, opt-out HIV testing. Methods.A retrospective analysis nested within a prospective HIV clinical cohort study evaluated patients who established initial outpatient treatment for HIV infection at the University of Alabama at Birmingham 1917 HIV/AIDS Clinic from 1 January 2000 through 31 December 2005. Survival methods were used to evaluate the impact of missed visits during the first year of care on subsequent mortality in the context of other baseline sociodemographic, psychosocial, and clinical factors. Mortality was ascertained by query of the Social Security Death Index as of 1 August 2007. Results.Among 543 study participants initiating outpatient care for HIV infection, 60% missed a visit within the first year. The mortality rate was 2.3 deaths per 100 person-years for patients who missed visits, compared with 1.0 deaths per 100 person-years for those who attended all scheduled appointments during the first year after establishing outpatient treatment (P=.02). In Cox proportional hazards analysis, higher hazards of death were independently associated with missed visits (hazard ratio, 2.90; 95% confidence interval, 1.28 6.56), older age (hazard ratio, 1.58 per 10 years of age; 95% confidence interval, 1.12 2.22), and baseline CD4+ cell count <200 cells/mm3 (hazard ratio, 2.70; 95% confidence interval, 1.00 7.30). Conclusions.Patients who missed visits within the first year after initiating outpatient treatment for HIV infection had more than twice the rate of long-term mortality, compared with those patients who attended all scheduled appointments. We posit that early missed visits are not causally responsible for the higher observed mortality but, rather, identify those patients who are more likely to exhibit health behaviors that portend increased subsequent mortality.

African Americans are disproportionately affected by both HIV and hypertension. Failure to modify risk factors for cardiovascular disease and chronic kidney disease such as hypertension among HIV-infected patients may attenuate the benefits conferred by combination antiretroviral therapy. In the general population, African Americans with hypertension are less likely to have controlled blood pressure than whites. However, racial differences in blood pressure control among HIV-infected patients are not well studied.
We conducted a cross-sectional study evaluating racial differences in hypertension prevalence, treatment, and control among 1,664 patients attending the University of Alabama at Birmingham HIV Clinic in 2013. Multivariable analyses were performed to calculate prevalence ratios (PR) with 95% confidence intervals (CI) as the measure of association between race and hypertension prevalence and control while adjusting for other covariates.
The mean age of patients was 47 years, 77% were male and 54% African-American. The prevalence of hypertension was higher among African Americans compared with whites (49% vs. 43%; p = 0.02). Among those with hypertension, 91% of African Americans and 93% of whites were treated (p = 0.43). Among those treated, 50% of African Americans versus 60% of whites had controlled blood pressure (systolic blood pressure <140 mmHg and diastolic blood pressure <90 mmHg) (p = 0.007). After multivariable adjustment for potential confounders, prevalence of hypertension was higher among African Americans compared to whites (PR 1.25; 95% CI 1.12-1.39) and prevalence of BP control was lower (PR 0.80; 95% CI 0.69-0.93).
Despite comparable levels of hypertension treatment, African Americans in our HIV cohort were less likely to achieve blood pressure control. This may place them at increased risk for adverse outcomes that disproportionately impact HIV-infected patients, such as cardiovascular disease and chronic kidney disease, and thus attenuate the benefits conferred by combination antiretroviral therapy.

Background. Human immunodeficiency virus (HIV) and AIDS continue to be associated with an underrecognized risk for suicidal ideation, attempted suicide, and completed suicide. Suicidal ideation represents an important predictor for subsequent attempted and completed suicide. We sought to implement routine screening of suicidal ideation and associated conditions using computerized patient-reported outcome (PRO) assessments. Methods. Two geographically distinct academic HIV primary care clinics enrolled patients who attended scheduled visits from December 2005 through February 2009. Touch-screen, computer-based PRO assessments were implemented into routine clinical care. Substance abuse, alcohol consumption, depression, and anxiety were assessed. The 9-item Patient Health Questionnaire assesses the frequency of suicidal ideation in the preceding 2 weeks. A response of “nearly every day” triggered an automated page to predetermined clinic personnel, who completed more detailed self-harm assessments. Results. Overall, 1216 patients (740 from the University of Alabama at Birmingham and 476 from the University of Washington) completed the initial PRO assessment during the study period. Patients were predominantly white (646 [53%]) and male (959 [79%]), with a mean age (⩾ standard deviation) of 44⩾10 years. Among surveyed patients, 170 (14%) endorsed some level of suicidal ideation, whereas 33 (3%) admitted suicidal ideation nearly every day. In multivariable analysis, suicidal ideation risk was lower with advancing age (odds ratio [OR], 0.74 per 10 years; 95% confidence interval [CI], 0.58–0.96) and was increased with current substance abuse (OR, 1.88; 95% CI, 1.03–3.44) and more-severe depression (OR, 3.91 for moderate depression [95% CI, 2.12–7.22] and 25.55 for severe depression [95% CI, 12.73–51.30]). Discussion. Suicidal ideation was associated with current substance abuse and depression. The use of novel technologies to incorporate routine self-reported screening for suicidal ideation and other health domains allows for timely detection and intervention for this life-threatening condition.

Few researchers have attempted to examine the mechanisms through which HIV-related stigma in the community is processed and experienced at an individual level by people living with HIV. We examined how the effects of perceived HIV stigma in the community on health outcomes for people living with HIV are mediated by internalized stigma and anticipated stigma. Participants (N = 203) from an HIV clinic completed self-report measures and their clinical data were obtained from medical records. Results suggested that the association between perceived community stigma and affective, cognitive, and mental health outcomes (self-esteem, depressive symptoms, avoidance coping, self-blame) are mediated by internalized stigma. Furthermore, a serial mediation model suggested that perceived community stigma leads to internalized stigma, which leads to anticipated community stigma, which in turn leads to lower medication adherence. The associations between perceived community stigma and interpersonal outcomes (social support, trust in physicians) were mediated by internalized stigma and anticipated stigma, again in a serial fashion (perceived community stigma leads to internalized stigma, which leads to anticipated stigma, which in turn leads to interpersonal outcomes). These results suggest that perceived HIV-related stigma in the community may cause people living with HIV to internalize stigma and anticipate stigmatizing experiences, resulting in adverse health and psychosocial outcomes—information that can be used to shape interventions.

Anti-Retroviral Agents - therapeutic use

Background Human papillomavirus (HPV) genotype testing has limited utility to identify human immunodeficiency virus‐infected (HIV+) women's risk for developing cervical cancer (CC) due to high positivity rate of high‐risk (HR) HPVs. We investigated the accuracy of HPV testing in isolation/in combination with CD4 and HIV viral load (VL) to identify HIV+ women at risk for developing CC. Methods Study consisted of 344 HIV+ women on combination antiretroviral therapy (cART), tested for cervical cytology/HPV using the Cobas test and had data on absolute CD4 count and VL measurements. We calculated the positive predictive value (PPV) and negative predictive value (NPV) of HPV testing, pre‐, post‐cART, and current CD4 and VL in isolation and in combinations to identify those with or free of higher than atypical squamous cells of unknown significance (ASCUS+) or low‐grade intraepithelial lesions (LSIL+). Results HPV test in combination with pre‐/post‐cART or current CD4 counts and VL had higher PPVs compared to HPV test alone for identifying ASCUS+ or LSIL+. PPV of HPV‐CD4 combinations yielded higher PPVs compared to HPV‐VL combinations. The NPVs with pre‐, post‐cART, or current CD4 count and VL in isolation or in combinations were comparable to that of HPV test alone. Conclusions Our results provide a more accurate tool for managing HIV+ women by combining Cobas HPV with CD4 and VL, especially those who had an undesirable pre‐cART CD4 and VL status. Our results also indicate the usefulness of CD4 and VL measurements to identify those at lower risk in the absence of HPV testing. The purpose of the study was to investigate the accuracy of HPV genotype testing in isolation and in combination with CD4 and HIV viral load (VL) for the identification of women infected with HIV at risk for developing cervical cancer. Our results indicated the importance of knowing CD4 and VL status in addition to HPV infection status in identifying women infected with HIV who are at risk for developing CC.

It is estimated that up to one-third of persons with known human immunodeficiency virus (HIV) infection in the United States are not engaged in care. We evaluated factors associated with patients' failure to establish outpatient HIV care at our clinic and found that females, racial minorities, and patients lacking private health insurance were more likely to be \"no shows.\" At the clinic level, longer waiting time from the call to schedule a new patient visit to the appointment date was associated with failure to establish care. Because increased numbers of patients will be in need of outpatient HIV care as a result of recent Centers for Disease Control and Prevention guidelines advocating routine HIV testing, it is imperative that strategies to improve access are developed to overcome the \"no show\" phenomenon.

Distribution of Health Care Expenditures for HIV-Infected Patients
2006
Background. Health care expenditures for persons infected with human immunodeficiency virus (HIV) in the United State determined on the basis of actual health care use have not been reported in the era of highly active antiretroviral therapy. Methods. Patients receiving primary care at the University of Alabama at Birmingham HIV clinic were included in the study. All encounters (except emergency room visits) that occurred within the University of Alabama at Birmingham Hospital System from 1 March 2000 to 1 March 2001 were analyzed. Medication expenditures were determined on the basis of 2001 average wholesale price. Hospitalization expenditures were determined on the basis of 2001 Medicare diagnostic related group reimbursement rates. Clinic expenditures were determined on the basis of 2001 Medicare current procedural terminology reimbursement rates. Results. Among the 635 patients, total annual expenditures for patients with CD4+ cell counts <50 cells/µL ($36,533 per patient) were 2.6-times greater than total annual expenditures for patients with CD4+ cell counts ⩾350 cells/µL ($13,885 per patient), primarily because of increased expenditures for nonantiretroviral medication and hospitalization. Expenditures for highly active antiretroviral therapy were relatively constant at ∼$10,500 per patient per year across CD4+ cell count strata. Outpatient expenditures were $1558 per patient per year; however, the clinic and physician component of these expenditures represented only $359 per patient per year, or 2% of annual expenses. Health care expenditures for patients with HIV infection increased substantially for those with more-advanced disease and were driven predominantly by medication costs (which accounted for 71%–84% of annual expenses). Conclusions. Physician reimbursements, even with 100% billing and collections, are inadequate to support the activities of most clinics providing HIV care. These findings have important implications for the continued support of HIV treatment programs in the United States.

Background There are no HPV‐based measures for managing anal cancer (AC) in HIV‐infected (HIV+) men who have sex with men (MSM) because of the high positivity of high‐risk (HR)‐HPVs. As next‐generation sequencing (NGS) is able to describe the composition of HPVs as percent (%) reads rather than positive vs negative results, we used NGS approach to detect HPVs in anal samples of HIV+ MSM to test its ability to differentiate those who are diagnosed with atypical squamous cells of unknown significance or greater (ASCUS+) from those who are free of such lesions and to understand the burden of HPV infections in relation to HPV vaccines. Methods Study included 81 HIV+ MSM characterized for demographics, patient‐reported outcome measures, HIV related laboratory measures and anal cytology. We summarized NGS HPV data using % read cut points (>0%‐>30%) and tested the relationship between % reads of HR‐HPVs and risk of ASCUS+ using logistic regression. Results Forty‐six HPVs were detected at the >0% read cut point. The prevalence of any HR‐HPVs varied from 100% to 40% with >0% to >30% reads while ≥99% were infected with HR‐HPVs included or not included in the 9 valent HPV vaccine at the >0% read cut point. MSM with >30% HR‐HPV reads were 4.5 times more likely to be diagnosed with ASCUS+ compared to ≤30% reads (P = .033). Conclusion NGS‐based approach is more accurate than PCR‐based HPV testing for identifying HIV+ MSM at risk for developing AC. We raise the concern regarding the efficacy of current HPV vaccines for preventing AC in this high‐risk population. Next‐generation sequencing‐based approach is more accurate than PCR‐based HPV testing for identifying HIV+ MSM at risk for developing anal cancer. We raise the concern regarding the efficacy of current HPV vaccines for preventing anal cancer in this high‐risk population.

Although prior authorization (PA) for prescription medications is widely employed for cost-containment for third-party insurers, it is a frustrating aspect of outpatient clinical care that imposes uncompensated costs to medical providers. To characterize these costs, we monitored the PA-associated administrative and operational process at the University of Alabama at Birmingham 1917 HIV Clinic over a 2-year period. A total of 288 PAs were processed with a mean (± standard deviation [SD]) of 3.1 ± 5.8 days delay in the patient's access to medication. A mean (±SD) of 26.8 ± 18.4 min was spent by the nurse practitioner and 6.5 ± 2.9 min was spent by a clerk per PA. Nearly three-quarters (73%) of PAs were approved, 18% were denied, and 10% were voided. The mean (±SD) pages of paperwork was 5.8 ± 6.5. The overall cost was $41.60 per PA. Although evidence supports that PA reduces third-party expenditures, it significantly delays medication accessibility for patients and imposes high costs that negatively impact operating margins for health care providers.

Adherence

Previous research suggests that people living with HIV (PLWH) sometimes internalize HIV-related stigma existing in the community and experience feelings of inferiority and shame due to their HIV status, which can have negative consequences for treatment adherence. PLWH’s interpersonal concerns about how their HIV status may affect the security of their existing relationships may help explain how internalized stigma affects adherence behaviors. In a cross-sectional study conducted between March 2013 and January 2015 in Birmingham, AL, 180 PLWH recruited from an outpatient HIV clinic completed previously validated measures of internalized stigma, attachment styles, and concern about being seen while taking HIV medication. Participants also self-reported their HIV medication adherence. Higher levels of HIV-related internalized stigma, attachment-related anxiety (i.e., fear of abandonment by relationship partners), and concerns about being seen by others while taking HIV medication were all associated with worse medication adherence. The effect of HIV-related internalized stigma on medication adherence was mediated by attachment-related anxiety and by concerns about being seen by others while taking HIV medication. Given that medication adherence is vitally important for PLWH to achieve long-term positive health outcomes, understanding interpersonal factors affecting medication adherence is crucial. Interventions aimed at improving HIV treatment adherence should address interpersonal factors as well as intrapersonal factors.
