Evaluation of a rapid HIV testing initiative in an urban, hospital-based dental clinic

Performing rapid HIV testing in nontraditional clinical settings such as dental clinics is a potential method for targeting high-risk individuals who may not otherwise access health care settings that offer HIV testing. In March 2008, Harlem Hospital Center, located in New York City, launched a counselor-based rapid HIV testing initiative in its on-site dental clinic. A full-time, trained counselor consented and tested patients as they waited for their appointments. HIV screening was performed using a whole-blood, finger-stick rapid HIV test. Through this initiative, 3864 HIV tests were performed from March 1, 2008 to December 31, 2009, representing 3565 unique individuals and 97.6% of dental patients approached for testing. Of those tested, the mean age was 38.5 years, with 47.1% female, 75.5% black, and 20.6% Hispanic. Self-reported HIV risk behaviors included 73.5% with recent unprotected heterosexual intercourse, 4.6% with recent or past injection drug use, and 2.6% who identified as men who have sex with men. Nineteen previously undiagnosed individuals (0.53%) were confirmed HIV positive. Of these individuals, mean age was 38.3 years with males representing 84.2%. Fifteen newly diagnosed patients (78.9%) were linked to care. Of those linked to care, median initial CD4 cell count was 317 cells/mm(3); 6 of these individuals (40%) had CD4 cell counts below 200 cells/mm(3). Our results demonstrate that a counselor-based rapid HIV testing program with linkage to specialized HIV care can be successfully integrated into the dental clinic setting.     

Drug use, attitudes, and behaviors of youth in an urban free clinic

A questionnaire regarding drug use, attitudes, and behaviors was completed by youths attending a free clinic on randomly selected evenings. Compared to a sample of suburban high school youths, the clinic youths were heavier drug users and were more antiestablishment in their attitudes and behaviors. The clinic youth as a whole tended to have antiestablishment attitudes but within the sample drug use was, with specific exceptions, not related to such attitudes. Youths whose first drug was not marijuana tended to be relatively heavy users, as compared to youths who started with marijuana. Data regarding reasons for use are reported. A brief discussion focuses on society's influence on the implications with the phenomena of drug use and free clinics.     

Improving cervical cancer screening rates in an urban HIV clinic

Human immunodeficiency virus (HIV)-infected women are at increased risk of invasive cervical cancer; however, screening rates remain low. The objectives of this study were to analyze a quality improvement intervention to increase cervical cancer screening rates in an urban academic HIV clinic and to identify factors associated with inadequate screening. Barriers to screening were identified by a multidisciplinary quality improvement committee at the Washington University Infectious Diseases clinic. Several strategies were developed to address these barriers. The years pre- and post-implementation were analyzed to examine the clinical impact of the intervention. A total of 422 women were seen in both the pre-implementation and post-implementation periods. In the pre-implementation period, 222 women (53%) underwent cervical cancer screening in the form of Papanicolaou (Pap) testing. In the post-implementation period, 318 women (75.3%) underwent cervical cancer screening (p < 0.01). Factors associated with lack of screening included fewer visits attended (pre: 4.2 ± 1.5; post: 3.4 ± 1.4; p < 0.01). A multidisciplinary quality improvement intervention was successful in overcoming barriers and increasing cervical cancer screening rates in an urban academic HIV clinic.     

Community-onset methicillin-resistant Staphylococcus aureus in an urban HIV clinic

OBJECTIVES: To determine the proportion of skin/soft tissue infections (SSTIs) and to determine risks for MRSA infection caused by methicillin-resistant Staphylococcus aureus (MRSA) in HIV-infected out-patients. METHODS: We conducted a prospective study of SSTIs in HIV-infected out-patients. A questionnaire was used to record MRSA risk factors and treatment. In vitro testing for antibiotic susceptibility, inducible clindamycin resistance, panton-valentine leucocidin (PVL) toxin, and the staphylococcal chromosomal cassette mec (SCCmec) type was performed using standardized methods. Treatment outcomes included resolution of primary site of infection, nonresolution of infection and reinfection and were confirmed at clinic visit and/or telephone follow-up. RESULTS: Forty-one of 44 patients had an SSTI caused by MRSA. African-Americans comprised 21 of 41 MRSA patients. The median CD4 count of MRSA patients was 411 cells/microL. Four patients required hospitalization and three patients had secondary bacteraemia. Twenty-one of 41 MRSA patients had healthcare-associated (HCA) MRSA risk factors including a history of prior MRSA infection (n=9) and hospitalization within 6 months (n=11). Other prevalent MRSA risk factors included receipt of systemic antibiotics within 6 months (n=21) and previous incarceration (n=19). Twenty-two patients had a significant non-HIV-related comorbid illness. The majority of isolates were susceptible to trimethoprim-sulfamethoxazole, tetracycline, and clindamycin. Inducible clindamycin resistance was detected in 0 of 16 erythromycin-resistant, clindamycin-susceptible MRSA isolates. Twenty-one of 24 isolates tested positive for SCCmec type IV. Twenty-four of 24 isolates tested positive for the PVL gene. Antibiotic treatment was discordant (bacteria nonsusceptible to antibiotic used) in eight MRSA patients. The primary SSTI resolved in 37 of 40 MRSA patients. Recurrence of infection at a site other than the primary site was relatively common (11 patients). CONCLUSIONS: We found a high rate of MRSA causing SSTI in community-dwelling patients. The majority of isolates were positive for PVL and SCCmec IV, which is typical of community-associated MRSA isolates causing SSTIs in the general population. Inducible clindamycin resistance was not detected. Most patients had MRSA risk factors. The initial site of infection resolved in most cases but subsequent MRSA infection was relatively common.     

Physician specialization and women's primary care services in an urban HIV clinic

To compare adherence to published primary care guidelines by general internal medicine and infectious diseases (ID) specialist physicians treating HIV-positive women we conducted a retrospective patient record review of 148 female HIV-positive patients seen at the Nathan Smith Clinic in New Haven, Connecticut, in 2001 and 2002. Four quality measures were defined to evaluate physician practices: annual cervical cancer screening, influenza vaccination and hyperlipidemia screening, and biennial mammography. Main outcome was the frequency of meeting each measure by generalist and ID-specialist physicians, and the two physician types were compared after controlling for patient clustering, age, and CD4 cell count. Among all measures, the rates of cervical cancer screening in 2001 were lowest among generalists (55%) and ID-specialists (47%) but not significantly different (odds ratio [OR] 1.26, 95% confidence interval [CI] 0.78 to 1.90), and the rates of hyperlipidemia screening in 2002 were highest for both generalists (98%) and ID-specialists (93%), but again not significant (OR 2.86, CI 0.30 to 27.6). No statistically significant differences were found between physician types for any quality measure, nor were significant differences found in the CD4 cell counts of patients of each physician type who received each service. Our results show potential for improvements in care among both generalist and ID-specialist physicians treating HIV-positive women.     

Limited effectiveness of antiviral treatment for hepatitis C in an urban HIV clinic

OBJECTIVE: To evaluate predictors and trends of referral for hepatitis C virus (HCV) care, clinic attendance and treatment in an urban HIV clinic. DESIGN AND METHODS: A retrospective cohort analysis in which 845 of 1318 co-infected adults who attended the Johns Hopkins HIV clinic between 1998 and 2003 after an on-site viral hepatitis clinic was opened, attended regularly (>/= 1 visit/year for >/= 2 years). Logistic regression was used to examine predictors of referral. RESULTS: A total of 277 (33%) of 845 were referred for HCV care. Independent predictors of referral included percentage elevated alanine aminotransferase levels [adjusted odds ratio (AOR) for 10% increase,1.16; 95% confidence interval (CI), 1.10-1.22] and CD4 cell count > 350 cells/microl (AOR, 3.20; 95% CI, 2.10-4.90), while injection drug use was a barrier to referral (AOR, 0.26; 95% CI, 0.11-0.64). Overall referral rate increased from < 1% in 1998 to 28% in 2003; however, even in 2003, 65% of those with CD4 cell count > 200 cells/microl were not referred. One hundred and eighty-five (67%) of 277 referred kept their appointment, of whom 32% failed to complete a pre-treatment evaluation. Of the remaining 125, only 69 (55%) were medically eligible for treatment, and 29 (42%) underwent HCV treatment. Ninety percent of 29 were infected with genotype 1 and 70% were African American; six (21%) achieved sustained virologic response (SVR). Only 0.7% of the full cohort achieved SVR. CONCLUSIONS: Although the potential for SVR and the recent marked increase in access to HCV care are encouraging, overall effectiveness of anti-HCV treatment in this urban, chiefly African American, HCV genotype 1 HIV clinic is extremely low. New therapies and treatment strategies are an urgent medical need.     

Client satisfaction with rapid HIV testing: comparison between an urban sexually transmitted disease clinic and a community-based testing center

Rapid HIV testing allows same-day results, increasing the number of persons who learn their HIV status. Understanding how clients in different settings perceive rapid testing may increase acceptance of this technology. From June 1999 to August 2001 we interviewed 256 clients at a publicly funded urban sexually transmitted disease (STD) clinic and 1201 clients at a community- based HIV counseling, testing, and referral center (Los Angeles Gay and Lesbian Center; LAGLC) about their posttest satisfaction with rapid HIV testing. HIV prevalence was 3.9% at the STD clinic and 5.3% at the LAGLC. In multivariate analysis, adjusting for age, sexual orientation, race/ethnicity, history of STDs, self-perceived HIV risk, prior HIV test and HIV testing results, clients at the STD clinics (versus LAGLC) were more likely to find testing stressful (adjusted odds ratio [AOR]: 1.75, 95% confidence limits [CL]: 1.27, 2.42) and feel that they received their results too quickly (AOR: 2.05, 95% CL: 1.39, 3.03). Latinos (versus whites) were more likely to report that they received their results too quickly (AOR: 4.99, 95% CL: 3.48, 7.14) and that it would be better to wait a week for HIV test results (AOR: 2.48, 95% CL: 1.51, 4.09). Further research may elucidate the reasons why some groups prefer to wait for results, and enable policymakers to better design strategies to reach high-risk groups with rapid HIV testing.     

Measurement of retention in care among adults infected with HIV in an urban clinic

Adults infected with HIV live longer when they receive regular medical care, yet many adults are not retained in care. Providers measure retention in order to evaluate interventions to improve retention and quality of HIV care. However, multiple measures for retention exist. This study compares two methods of operationalizing retention and evaluates the contribution of individual characteristics on the likelihood of retention. A chart review was performed for a random sample of 212 active clients of an urban HIV primary care clinic. Data on clinic utilization, sex, age, race, mental illness, substance use, AIDS diagnosis, language, and housing were collected for each participant. Clinic utilization data were used to classify participants for retention status and to score them by frequency of visits. Binary logistic regression analysis was compared with ordinal logistic regression analysis, using distinct retention measures as outcome variables. In the binary model, those with a history of substance use were about half as likely to be retained (OR 0.52, 95% CI 0.29-0.94) and those with an AIDS diagnosis were more than twice as likely to be retained (OR 2.18, 95% CI 1.17-4.09). These characteristics were significant predictors in the ordinal model, with the additional finding that those reporting English as a primary language were less likely to have higher retention scores (OR 0.40, 95% CI 0.19-0.84). An ordinal score for retention can identify unexpected predictors, but a dichotomous measure of retention may be easier to use and interpret for providers involved in retention-related quality improvement activities.     

Evaluation of opt-out inpatient HIV screening at an urban teaching hospital

This study evaluated opt-out inpatient HIV screening delivered by admitting physicians, and compared number of HIV tests and diagnoses to signs and symptoms-directed HIV testing (based on physician orders) in the emergency department (ED). The opt-out inpatient HIV screening program was conducted over a one year period in patients who were admitted to the 386-bed University of California San Diego (UCSD) teaching hospital. Numbers of HIV tests and diagnoses were compared to those observed among ED patients who underwent physician-directed HIV testing during the same time period. Survey data were collected from a convenience sample of patients and providers regarding the opt-out testing program. Among 8488 eligible inpatients, opt-out HIV testing was offered to 3017 (36%) patients, and rapid antibody testing was performed in 1389 (16.4%) inpatients, resulting in 6 (0.4% of all tests) newly identified HIV infections (5/6 were admitted through the ED). Among 27,893 ED patients, rapid antibody testing was performed in 88 (0.3%), with 7 (8.0% of all tests) new HIV infections identified. HIV diagnoses in the ED were more likely to be men who have sex with men (MSM) (p?=?0.029) and tended to have AIDS-related opportunistic infections (p?=?0.103) when compared to HIV diagnoses among inpatients. While 85% of the 150 physicians who completed the survey were aware of the HIV opt-out screening program, 44% of physicians felt that they did not have adequate time to consent patients for the program, and only 30% agreed that a physician is best-suited to consent patients.

In conclusion, the yield of opt-out HIV rapid antibody screening in inpatients was comparable to the national HIV prevalence average. However, uptake of screening was markedly limited in this setting where opt-out screening was delivered by physicians during routine care, with limited time resources being the major barrier.     

Training the next generation of HIV providers: impact of trainees on patient satisfaction in an urban HIV clinic

For persons living with HIV and AIDS (PLWHA), care by an HIV-specialist improves outcomes and satisfaction with one's HIV primary care provider (PCP) promotes engagement with care. In the United States, we are facing a workforce shortage of HIV providers. As we aim to train a new generation of HIV providers, it is unclear how PLWHA perceive their experience when cared for by trainees compared to experienced providers. Therefore we assessed patient satisfaction with HIV providers, both trainees in an HIV Primary Care residency program and HIV-specialists. A secondary objective was to evaluate providers’ performance in adhering to standard management guidelines for HIV-associated and non-HIV-associated conditions. We surveyed 75 PLWHA, including 51 (68%) assigned to an HIV-specialist PCP and 24 (32%) to a trainee PCP. Overall patient satisfaction on a 10-point scale was similar (mean 9.6 HIV-specialist vs 9.7 trainee, p?=?0.71) and remained similar in multivariate logistic regression analysis when controlling for patient age, gender, race, and recently establishing care (Odds Ratio 1.1, 95% Confidence Interval 0.3–5.0). Participants in the trainee group were more likely to feel their provider “always” spent enough time with them (100% vs 81%, p?=?0.03). Adherence to HIV guidelines was similar, though trainees were more likely to document counseling on risk reduction (83% vs 47%, p?=?0.005) and adherence to antiretroviral therapy (100% vs 66%, p?=?0.001). In conclusion, in a structured HIV-training program, residents can provide subspecialty level care in an HIV continuity clinic with levels of performance and patient satisfaction equivalent to those of experienced specialists.     

Patients' attitudes towards increasing the offer of HIV testing in primary and secondary care

The UK National Guidelines on HIV testing (2008) recommend routinely offering an HIV test to patients in certain clinical settings. We wished to investigate the acceptability of implementing these guidelines in a population with a low HIV prevalence. Patients accessing primary and secondary care were asked to circle one of the five responses to a series of statements regarding HIV testing. Of the 616 respondents, 579 (94%) stated they would be willing to be tested if presenting with a condition known to be associated with HIV. Four hundred and forty out of 616 (71%) stated they would be willing to be tested as part of their routine care, while 445/616 (72%) stated they would be willing to have the result in their main medical notes. Although the patients' responses were largely receptive to increased testing, we encountered notable negative attitudes to the project from professional and administrative staff. Resistance to increased HIV testing may be related to health-care workers rather than patients.     

Acute hepatitis C virus in an HIV clinic: a screening strategy, risk factors, and perception of risk

Acute hepatitis C virus (HCV) infection is being acquired undetected among HIV-infected individuals. A practical way to regularly screen HIV-infected patients for acute HCV irrespective of perceived risk or symptoms is needed. We piloted implementation of an acute HCV screening strategy using routine HIV clinical care schedules and the least costly blood tests, in a Rhode Island HIV care center. Study participants had ongoing HCV risk, completed questionnaires encompassing risk behaviors and perception of risk, and were screened with quarterly alanine aminotransferase (ALT). ALT rise triggered HCV RNA testing, with pooled rather than individual specimen HCV RNA testing for underinsured participants. Participants were primarily older, college-educated men who have sex with men (MSM) with history of sexually transmitted infection other than HIV. One of 58 participants developed acute HCV in 50 person-years of observation for an annual incidence of 2.0% per year (95% confidence interval [CI] 0.05-11.1%). The majority (54%) of MSM did not perceive that traumatic sexual and drug practices they were engaging in put them at risk for HCV. Unprotected sex often occurred under the influence of drugs or alcohol. Self-reported HCV risk and participation in several risk behaviors declined during the study. It was possible to collect frequent ALTs in a busy HIV clinic with 71% of total projected ALTs obtained and 88% of participants having at least one ALT during the 9-month follow-up period. All instances of ALT rise led to reflexive HCV RNA testing. Tracking quarterly ALT for elevation to systematically prompt HCV RNA testing before seroconversion is a promising approach to screen for acute HCV in a real-world HIV clinical setting.     

Self-perceived risk of HIV infection and attitudes about preexposure prophylaxis among sexually transmitted disease clinic attendees in South Carolina

Several domestic and international trials of the use of preexposure prophylaxis (PrEP) for HIV prevention are ongoing among groups at high risk for HIV infection. The objective of this cross-sectional study was to assess self-perceived risk of HIV infection and attitudes about PrEP among 405 sexually transmitted disease (STD) clinic attendees in South Carolina. Self-percieved risk of HIV infection and attitudes about PrEP were assessed using three questions from a self-administered survey. Ordinal logistic regression and logistic regression were used to evaluate differences in risk perception for HIV infection and attitudes about the use of PrEP among risk groups. Compared to heterosexual participants, homosexual participants were significantly more likely to have knowledge of PrEP (odds ratio [OR]=6.7, 95% confidence interval [CI]: 1.70-26.1). Compared to those participants who had 1 sexual partner in the past 3 months, individuals who had 2 to 4 sexual partners in the past 3 months were approximately 2.35 times as likely to have a lower level of agreement with the statement "I believe I am at risk of getting HIV" (p=0.0003). Compared to female participants, respondents who were male were approximately 2.8 times as likely to have a lower level of agreement with the statement "If I had to it would be very difficult for me (or my partner) to both use condoms and take daily pills to prevent HIV infection" (p<0.0001). These results suggest the need for the creation of PrEP implementation programs that are tailored to self-perceived risk perception, age, and gender.     

Improving anal cancer screening in an ambulatory HIV clinic: experience from a quality improvement initiative

Evidence suggests that persons living with HIV (PLWH) are at increased risk for anal cancer. Early detection of anal cancer is an important prevention measure, but screening rates have been low. This report describes the experience of a quality improvement initiative to increase anal cancer screening at an HIV-specialty clinic. Chart reviews were conducted for three time periods: baseline year, prior to program discussion; transition year, during planning; and implementation year, during program availability. Odds ratios using Fisher's exact test showed that the odds of receiving anal cancer screening increased significantly in the transition year, odds ratio (OR)?=?2.859, 95% confidence interval (CI): [1.798; 4.546], Fisher's z?=?4.40, p??8.2, p?相似文献
