Hospitalizations for Cardiovascular Disease in African Americans and Whites with HIV/AIDS

Therapeutic advances have resulted in an epidemiological shift in the predominant causes of hospitalization for patients with HIV/AIDS. An emerging cause for hospitalization in this patient population is cardiovascular disease (CVD); however, data are limited regarding how this shift affects different racial groups. The objective of this observational, retrospective study was to evaluate the association between race and hospitalization for CVD in African Americans and whites with HIV/AIDS and to compare the types of CVD-related hospitalizations between African Americans and whites with HIV/AIDS. Approximately 1.5 million hospital discharges from the US National Hospital Discharge Surveys for the years of 1996 to 2008 were identified. After controlling for potential confounders, the odds of CVD-related hospitalization in patients with HIV/AIDS were 45% higher for African Americans than whites (odds ratio [OR]=1.45, 95% CI, 1.39–1.51). Other covariates that were associated with increased odds of hospitalization for CVD included chronic kidney disease (OR=1.43, 95% CI, 1.36–1.51), age≥50 years (OR=3.22, 95% CI, 2.94–3.54), region in the Southern United States (OR=1.17, 95% CI, 1.11–1.23), and Medicare insurance coverage (OR=1.71, 95% CI, 1.60–1.83). Male sex was not significantly associated with the study outcome (OR=0.99, 95% CI, 0.96–1.02). Compared to whites with HIV/AIDS, African Americans with HIV/AIDS had more hospitalizations for heart failure and hypertension, but fewer hospitalizations for stroke and coronary heart disease. In conclusion, African Americans with HIV/AIDS have increased odds of CVD-related hospitalization as compared to whites with HIV/AIDS. Furthermore, the most common types of CVD-related hospitalizations differ significantly in African Americans and whites. (Population Health Management 2012;16:201–207

The State of Disparities in Opportunistic Infection Prophylaxis for Blacks With HIV/AIDS

The purpose of this review is to identify and analyze published studies that have evaluated disparities for opportunistic infection (OI) prophylaxis between Blacks and Whites with HIV/AIDS in the United States

Comparative Value of Four Measures of Retention in Expert Care in Predicting Clinical Outcomes and Health Care Utilization in HIV Patients

This study compared the ability of four measures of patient retention in HIV expert care to predict clinical outcomes. This retrospective study examined Veterans Health Administration (VHA) beneficiaries with HIV (ICD-9-CM codes 042 or V08) receiving expert care (defined as HIV-1 RNA viral load and CD4 cell count tests occurring within one week of each other) at VHA facilities from October 1, 2006, to September 30, 2008. Patients were ≥18 years old and continuous VHA users for at least 24 months after entry into expert care. Retention measures included: Annual Appointments (≥2 appointments annually at least 60 days apart), Missed Appointments (missed ≥25% of appointments), Infrequent Appointments (>6 months without an appointment), and Missed or Infrequent Appointments (missed ≥25% of appointments or >6 months without an appointment). Multivariable nominal logistic regression models were used to determine associations between retention measures and outcomes. Overall, 8,845 patients met study criteria. At baseline, 64% of patients were virologically suppressed and 37% had a CD4 cell count >500 cells/mm3. At 24 months, 82% were virologically suppressed and 46% had a CD4 cell count >500 cells/mm3. During follow-up, 13% progressed to AIDS, 48% visited the emergency department (ED), 28% were hospitalized, and 0.3% died. All four retention measures were associated with virologic suppression and antiretroviral therapy initiation at 24 months follow-up. Annual Appointments correlated positively with CD4 cell count >500 cells/mm3. Missed Appointments was predictive of all primary and secondary outcomes, including CD4 cell count ≤500 cells/mm3, progression to AIDS, ED visit, and hospitalization. Missed Appointments was the only measure to predict all primary and secondary outcomes. This finding could be useful to health care providers and public health organizations as they seek ways to optimize the health of HIV patients

Economic Analysis of Carboplatin Versus Cisplatin in Lung and Ovarian Cancer

Objective: To conduct an economic analysis on the use of carboplatin versus cisplatin over multiple courses in patients with lung [nonsmall cell lung cancer (NSCLC) and small cell lung cancer (SCLC)] or ovarian cancer. Design: This 1-year study was a prospective, multicentre, cost-minimisation evaluation. Direct medical resource utilisation and costs associated with carboplatin and cisplatin administration over 3 to 6 courses of treatment were measured and compared. The perspective of this evaluation was that of the payer. Setting: A convenience sample of 16 sites representing a mix of cancer centres, outpatient clinics, medical centres and managed-care sites in a general practice oncology setting participated. Patients and interventions: Patients were included in this study if they were newly diagnosed with NSCLC, SCLC or ovarian cancer, had not received prior chemotherapy, received either carboplatin or cisplatin as their treatment (additional chemotherapy agents were allowed), and received at least 3 courses of carboplatin or cisplatin therapy up to a maximum of 6 courses. Patients receiving more than 6 courses of therapy were included in this study, but data collection on those patients stopped after the sixth course. Individuals involved with data collection at all sites were trained via on-site and/or teleconference training. Site visits were made to assure reliability of at least 0.80. Data were collected and compiled via a fax transmission process that scans directly through optical mark and character recognition into a computer database. Outcome measures included costs of: medications, emergency room visits, physician/clinic/laboratory visits, home healthcare visits, transfusions, special procedures, consultations, hospitalisations and other/miscellaneous costs. Main outcome measures and results: Of 220 patients, 164 met the study criteria (response rate = 74.2%) with 95 patients in the carboplatin group (NSCLC = 45, SCLC = 18, ovarian = 32) and 69 in the cisplatin group (NSCLC = 36, SCLC = 21, ovarian = 12). The average number of courses were: NSCLC = 4.3 and 4.2, SCLC = 4.3 and 4.8, and ovarian = 4.7 and 5.1, respectively, for carboplatin and cisplatin. The total costs (treatment and toxicity) associated with the use of carboplatin were higher in NSCLC, similar in SCLC but lower in ovarian cancer. Conclusions: These results indicate that overall treatment costs may vary depending on cancer type, even when the same drugs are used. The total costs (treatment plus toxicity costs) associated with the use of carboplatin were higher than those of cisplatin in patients with NSCLC, similar in SCLC, but lower in ovarian cancer.Ovarian-cancer, Carboplatin, Cisplatin, Non-small-cell-lung-cancer, Small-cell-lung-cancer, Cost-minimisation, Antineoplastics
