10-Year Survival of Patients with AIDS Receiving Antiretroviral Therapy in Haiti

Long-term management of AIDS in resource-constrained settings is a tremendous challenge. This report from Haiti offers evidence that antiretroviral therapy can be successfully delivered with significant clinical benefit for more than a decade.

Stress, Socializing, and Other Motivations for Smoking Among the Lesbian, Gay, Bisexual, Transgender, and Queer Community in New York City

Purpose: This study contributes to the emerging literature on lesbian, gay, bisexual, transgendered, and queer (LGBTQ) health disparities and tobacco use by examining the motivations for smoking among the New York City (NYC) LGBTQ population. Approach: We used grounded theory and blended methods from 3 grounded theorists—Strauss, Corbin, and Charmaz—for data collection, coding, and analysis. Setting: NYC has extensive legislation to prevent smoking; however, the current smoking prevalence of homosexuals is double that of heterosexuals. Participants: Study participants were leaders from 23 NYC LGBTQ organizations. Leaders were chosen to establish a relationship with community and to ensure cultural sensitivity. Eligibility criteria required holding a leadership position in an organization serving the NYC LGBTQ community. Methods: Interviews were transcribed verbatim and uploaded into Dedoose for analysis. An initial code list was developed from the interview guide. Key themes were identified as the themes with the most number of quotes. Results: Three key themes emerged from our interviews: image, socializing, and stress. Smoking was reported to be a socialization aid and a maladaptive coping technique for stress arising from interactions of conflicting identities. Conclusion: Future smoking cessation interventions among the LGBTQ community should equip smokers with healthy coping mechanisms that address the stressors that arise from the intersections of smokers’ many identities.

Can your patients with heart failure see? The prevalence of visual impairment among adults with heart failure

Heart failure (HF) management requires medication and diet adherence, as well as daily weight and fluid monitoring. In addition, patients are often asked to follow specific written instructions after hospital discharge. All of these activities require adequate visual acuity (VA). Yet, to date, little is known about the visual function of adults with HF. Herein, we provide the first national estimates of the prevalence of visual impairment (VI) among adults with HF.

Observational study of the differential impact of time-varying depressive symptoms on all-cause and cause-specific mortality by health status in community-dwelling adults: the REGARDS study

Objective To assess the association between time-varying depressive symptoms with all-cause and cause-specific mortality. Design The REGARDS (Reasons for Geographic and Racial Differences in Stroke) is a national, population-based longitudinal study conducted from 2003 to 2007. Setting General continental US communities. Participants 29 491 black and white US adults ≥45 years randomly sampled within race–sex–geographical strata. Exposure Elevated depressive symptoms (Centre for Epidemiologic Studies Depression (CES-D) 4≥4) measured at baseline and on average 5 and 7 years later. Main outcome measures Cox proportional hazard regression models assessed cancer, non-cardiovascular (cardiovascular disease (CVD)), CVD and all-cause mortality. Results The average age was 64.9 years; 55% were women; 41% black; 11.0% had elevated depressive symptoms; 54% had poor, fair or good health. Time-varying depressive symptoms were significantly associated with non-CVD (adjusted HR (aHR)=1.29, 95% CI 1.16 to 1.44) and all-cause (aHR=1.24, 95% CI 1.14 to 1.39), but not cancer (aHR=1.15, 95% CI 0.96 to 1.38) or CVD (aHR=1.13, 95% CI 0.98 to 1.32) death adjusting for demographics, chronic clinical diseases, behavioural risk factors and physiological factors. Depressive symptoms were related to all-cause (aHR=1.48, 95% CI 1.27 to 1.78), CVD (aHR=1.37, 95% CI 0.99 to 1.91), non-CVD (aHR=1.54, 95% CI 1.24 to 1.92) and cancer (aHR=1.36, 95% CI 0.97 to 1.91) death in those who reported excellent or very good health. The analyses of the association between one measure of baseline depressive symptoms and mortality analyses yielded similar results. Conclusions Time-varying depressive symptoms confer an increased risk for all-cause mortality, CVD, non-CVD death and cancer death, particularly in those with excellent or very good health. These findings may have implications for timely treatment, regardless of health status.

Outcomes after antiretroviral therapy during the expansion of HIV services in Haiti

Background We report patient outcomes after antiretroviral therapy (ART) initiation in a network of HIV facilities in Haiti, including temporal trends and differences across clinics, during the expansion of HIV services in the country. Methods We assessed outcomes at 12 months after ART initiation (baseline) using routinely collected data on adults (≥15 years) in 11 HIV facilities from July 2007-December 2013. Outcomes include death (ascertained from medical records), lost to follow-up (LTF) defined as no visit > 365 days from ART initiation, and retention defined as being alive and attending care ≥ 365 days from ART initiation. Outcomes were compared across calendar year of ART initiation and across facilities. Risk factors for death and LTF were assessed using Cox proportional hazards and competing risk regression models. Results Cumulatively, 9,718 adults initiated ART with median age 37 years (IQR 30–46). Median CD4 count was 254 cells/uL (IQR 139–350). Twelve months after ART initiation, 4.4% (95% CI 4.0–4.8) of patients died, 21.7% (95% CI 20.9–22.6) were LTF, and 73.9% (95% CI 73.0–74.8) were retained in care. Twelve-month mortality decreased from 13.8% among adults who started ART in 2007 to 4.4% in 2013 (p<0.001). Twelve-month LTF after ART start was 29.2% in 2007, 18.7% in 2008, and increased to 30.1% in 2013 (p<0.001). Overall, twelve-month retention after ART start did not change over time but varied widely across facilities from 61.1% to 86.5%. Conclusion Expansion of HIV services across Haiti has been successful with increasing numbers of patients initiating ART and decreasing twelve-month mortality rates. However, overall retention has not improved, despite differences across facilities, suggesting additional strategies to improve engagement in care are needed.

Fifteen years of HIV and syphilis outcomes among a prevention of mother-to-child transmission program in Haiti: from monotherapy to Option B+

To evaluate mother and infant outcomes in the largest prevention of mother‐to‐child‐transmission (PMTCT) programme in Haiti in order to identify gaps towards elimination of HIV and syphilis.

Impact of Hospitalist-Led Interdisciplinary Antimicrobial Stewardship Interventions at an Academic Medical Center

BACKGROUND Approximately 20%-50% of antimicrobial use in hospitals is inappropriate. Limited data exist on the effect of frontline provider engagement on antimicrobial stewardship outcomes. METHODS A three-arm pre-post quality improvement study was conducted on three adult internal medicine teaching services at an urban academic hospital. Data from September through December 2016 were compared to historic data from corresponding months in 2015. Intervention arms were (1) Educational bundle (Ed-only); (2) Educational bundle plus antimicrobial stewardship rounds twice weekly with an infectious disease-trained clinical pharmacist (Ed+IDPharmDx2); and (3) Educational bundle plus internal medicine-trained clinical pharmacist embedded into daily attending rounds (Ed+IMPharmDx5). RESULTS Total antibiotic use decreased by 16.8% (p < 0.001), 6.8% (p = 0.08), and 33.0% (p < 0.001) on Ed-only, Ed+IDPharmDx2, and Ed+IMPharmDx5 teams, respectively. Broad-spectrum antibiotic use decreased by 26.2% (p < 0.001), 7.8% (p = 0.09), and 32.4% (p < 0.001) on the Ed-only, Ed+IDPharmDx2, and Ed+IMPharmDx5 teams, respectively. Duration of inpatient antibiotic therapy decreased from 4 to 3 days on the Ed+IMPharmDx5 team (p = 0.01). Length of stay for patients who received any antibiotic decreased from 9 to 7 days on the Ed-only team (p < 0.001) and from 9 to 6 days on the Ed+IMPharmDx5 team (p < 0.001). There was no significant change in 30-day readmission to the same facility, transfer to ICU, or in-hospital mortality for any team. CONCLUSION Multidisciplinary, frontline provider-driven approaches to antimicrobial stewardship may contribute to reduced antibiotic use and length of hospital stay.

Predicting death and lost to follow-up among adults initiating antiretroviral therapy in resource-limited settings: Derivation and external validation of a risk score in Haiti

Background Over 18 million adults have initiated life-saving antiretroviral therapy (ART) in resource-poor settings; however, mortality and lost-to-follow-up rates continue to be high among patients in their first year after treatment start. Clinical decision tools are needed to identify patients at high risk for poor outcomes in order to provide individualized risk assessment and intervention. This study aimed to develop and externally validate risk prediction tools that estimate the probability of dying or of being lost to follow-up (LTF) during the year after starting ART. Methods We used a derivation cohort of 7,031 adults age 15–70 years initiating ART from 2007 to 2013 at 6 clinics in Haiti; 242 (3.5%) had documented death and 1,521 (21.6%) were LTF at 1 year after starting ART. The following routinely collected data were used as predictors in two logistic regression models (one to predict death and another to predict LTF): age, gender, weight, CD4 count, WHO Stage, and diagnosis of tuberculosis (TB). The validation cohort consisted of 1,835 adults initiating ART at a different HIV clinic in Haiti during 2012. We assessed model discrimination by measuring the C-statistic, and measured model calibration by how closely the predicted probabilities approximated actual probabilities of the two outcomes. We derived a nomogram and a point-based risk score from the predictive models. Findings The model predicting death within the year after starting ART had a C-statistic of 0.75 (95% CI 0.74 to 0.81). There was no evidence for significant overfitting and the predictions were well calibrated. The strongest predictors of 1-year mortality were male gender, low weight, low CD4 count, advanced WHO stage, and the absence of TB. In the validation cohort, the C-statistic was 0.69 (95% CI 0.59 to 0.77). A point-based risk score for death had a C-statistic 0.73 (95% CI 0.69 to 0.76) and categorizes patients as low risk (<2% risk of death), average risk (3–4%), and high-risk (8–10%) and very high-risk (14–19%) with likelihood ratios to be used in settings where the baseline risk is different from our study population. The model predicting LTF did not discriminate well (C-statistic 0.59). Conclusions A simple risk-score using routinely collected data can predict 1-year mortality after ART initiation for HIV-positive adults in Haiti. However, predicting lost to follow-up using routinely collected data was not as successful. The next step is to assess whether use of this risk score can identify patients who need tailored services to reduce mortality in resource-poor settings such as Haiti.

Evaluating Gaps in Care of Malnourished Patients on General Medicine Floors in an Acute Care Setting

BACKGROUND As described in detail in the literature, patients identified with malnutrition are at increased risk for poor clinical outcomes. Despite this knowledge, malnourished patients do not always receive optimal nutrition management while admitted into a hospital because of what we describe as gaps in care throughout their admission. We hypothesized that the 3 main gaps in care were poor dietitian-doctor communication, excessive time spent nil per os (NPO) for procedures and testing, and/or inaccurate or incomplete dietary discharge instructions. The objectives of this study were to determine and to characterize gaps in nutrition care after a malnutrition diagnosis. METHODS This retrospective study involved postdischarge chart reviews of malnourished adult medicine patients admitted to an acute care facility from September 1, 2014, to November 30, 2014 (n = 242). RESULTS Of the malnourished patients, 76% had at least 1 gap in care. The most prevalent gap (68%) involved discharge diet instructions, most often because of the omission of the dietitian recommendation for oral supplementation. Thirty-five percent of malnourished patients had a gap in care because of procedures or testing extending the period held NPO, and 13% had a gap in care because of poor communication, thus delaying orders and/or interventions. CONCLUSIONS This is the first study to evaluate gaps in care of patients diagnosed with malnutrition. Identification of these gaps allows us the opportunity to develop strategies for this vulnerable population to improve areas such as discharge documentation and time spent NPO to provide the best and safest nutrition care.

Utility of Diagnostic Bone Biopsies in the Management of Osteomyelitis through Retrospective Analysis: How Golden is this Gold Standard?

Abstract Background Bone biopsy is considered the gold standard for diagnosis and treatment of osteomyelitis (OM), but few studies have investigated the extent to which it influences antimicrobial therapy in non-vertebral bones. The purpose of this study was to evaluate clinician-initiated changes to empiric antimicrobial therapy after obtaining bone biopsy results. A secondary aim was to identify predictors of a positive bone culture. Methods We retrospectively reviewed all cases of non-vertebral OM in patients who underwent image-guided bone biopsies between 2009 and 2016. Data on pathologic and microbiologic yield were collected and logistic regression was used to determine potential factors affecting the microbiologic yield. Post-biopsy empiric antibiotics and final antibiotics were compared with determine if there was a change in antibiotic treatment after biopsy results were reported. Results We evaluated 203 bone biopsies in 185 patients. Samples from 115 (57%) cases were sent to pathology, of which 33 (29%) confirmed OM. All samples were sent to microbiology and 57 (28%) yielded a positive result. Diabetes (OR=2.39, P = 0.021) and white blood cell count (OR=1.13, P = 0.006) were significantly associated with positive bone cultures in multivariate analyses. There was no association between positive cultures and number of samples cultured, needle size, prior antibiotic use, or antibiotic-free days. Post-biopsy empiric antibiotics were given in 138 (68%) cases. Therapy was narrowed to target specific organisms in seven cases and changed due to inadequate empiric treatment in three cases. Targeted therapy was initiated in 4/65 cases, in which empiric antibiotics had been initially withheld. While final antibiotics were withheld in 38/146 with negative bone cultures, empiric antibiotics were discontinued in only eight cases. Conclusion In patients with non-vertebral OM, bone biopsy cultures rarely yielded results that necessitated changes in antibiotic management. Identified bone organisms were treated by empiric therapy in most patients. While bone biopsy remains the gold standard diagnostic test for OM, further work is needed to identify patients whose management may be impacted by this procedure.
