RESUMO
OBJECTIVES: To describe the demographics, clinical characteristics, and outcomes of hospitalized adults with coronavirus disease 2019 (COVID-19) in an academic medical center in the southern United States. METHODS: Retrospective, observational cohort study of all adult patients (18 years and older) consecutively admitted with laboratory-confirmed severe acute respiratory syndrome-coronavirus-2 infection between March 13 and April 25, 2020 at the University of Mississippi Medical Center. All of the patients either survived to hospital discharge or died during hospitalization. Demographics, body mass index, comorbidities, clinical manifestations, and laboratory findings were collected. Patient outcomes (need for invasive mechanical ventilation and in-hospital death) were analyzed. RESULTS: One hundred patients were included, 53% of whom were women. Median age was 59 years (interquartile range 44-70) and 66% were younger than 65. Seventy-five percent identified themselves as Black, despite representing 58% of hospitalized patients at our institution in 2019. Common comorbid conditions included hypertension (68%), obesity (65%), and diabetes mellitus (31%). Frequent clinical manifestations included shortness of breath (76%), cough (75%), and fever (64%). Symptoms were present for a median of 7 days (interquartile range 4-7) on presentation. Twenty-four percent of patients required mechanical ventilation and, overall, 19% died (67% of those requiring mechanical ventilation). Eighty-four percent of those who died were Black. On multivariate analysis, ever smoking (odds ratio [OR] 5.9, 95% confidence interval [CI] 1.2-28.6) and history of diabetes mellitus (OR 5.9, 95% CI 1.5-24.3) were associated with mortality, and those admitted from home were less likely to die (vs outside facility, OR 0.2, 95% CI 0.0-0.7). Neither age, sex, race, body mass index, insurance status, nor rural residence was independently associated with mortality. CONCLUSIONS: Our study adds evidence that Black patients appear to be overrepresented in those hospitalized with and those who die from COVID-19, likely a manifestation of adverse social determinants of health. These findings should help guide preventive interventions targeting groups at higher risk of acquiring and developing severe COVID-19 disease.

BACKGROUND: Rapid antiretroviral therapy (ART), ideally initiated within twenty-four hours of diagnosis, may be crucial in efforts to increase virologic suppression and reduce HIV transmission. Recent studies, including demonstration projects in large metropolitan areas such as Atlanta, Georgia; New Orleans, Louisiana; San Francisco, California; and Washington D.C., have demonstrated that rapid ART initiation is a novel tool for expediting viral suppression in clinical settings. Here we present an evaluation of the impact of a rapid ART initiation program in a community-based clinic in Jackson, MS. METHODS: We conducted a retrospective chart review of patients who were diagnosed with HIV at Open Arms Healthcare Center or were linked to the clinic for HIV care by the Mississippi State Department of Health Disease Intervention Specialists from January 1, 2016 to December 31, 2018. Initial viral load, CD4+ T cell count, issuance of an electronic prescription (e-script), subsequent viral loads until suppressed and patient demographics were collected for each individual seen in clinic during the review period. Viral suppression was defined as a viral load less than 200 copies/mL. Rapid ART initiation was defined as receiving an e-script for antiretrovirals within seven days of diagnosis. RESULTS: Between January 1, 2016 and December 31, 2018, 70 individuals were diagnosed with HIV and presented to Open Arms Healthcare Center, of which 63 (90%) completed an initial HIV counseling visit. Twenty-seven percent of patients were provided with an e-script for ART within 7 days of diagnosis. The median time to linkage to care for this sample was 12 days and 5.5 days for rapid ART starters (p < 0.001). Median time from diagnosis to viral suppression was 55 days for rapid ART starters (p = 0.03), a 22 day decrease from standard time to viral suppression. CONCLUSION: Our results provide a similar level of evidence that rapid ART initiation is effective in decreasing time to viral suppression. Evidence from this evaluation supports the use of rapid ART initiation after an initial HIV diagnosis, including same-day treatment.

BACKGROUND: Mississippi, the poorest state in the US, has a very high prevalence of HIV and among the highest HIV infection rates and AIDS-adjusted mortality rates in the country. African Americans, who suffer the worst health care disparities in the US, account for 76% of people with HIV in MS. The purpose of this study is to describe those in care for HIV and determine the factors associated with anti-retroviral treatment (ART) and viral suppression. METHODS: The CDC's Medical Monitoring Project collects surveillance data from 23 project areas in the US, including Mississippi, using annual probability sampling of persons in care for HIV. Data were collected from in-person interviews and medical record abstraction in 2009. The surveillance period was the 12 months prior to the interview date. RESULTS: 212 randomly selected participants represented a nationally representative weighted sample of 3190.4. Participants had a mean of 3.71 provider visits during the surveillance period. Geometric mean for CD4 count = 438.91 (95% CI 402.25-475.56). Overall 80.80% (95% CI 75.30%- 86.29%) were on ART, and 68.12% (95% CI 62.69%-73-56%) had undetectable viral load. Males (65.15%) were less likely to achieve undetectable viral load compared to females (78.30%) after controlling for individuals who were on ART (p = 0.01). Viral suppression was not associated with age, race or sexual risk factors. CONCLUSIONS: Although Mississippi has a high proportion of individuals out of HIV care, the majority in care is on ART and has suppressed viral loads. However, men are less likely to achieve virological suppression than females.

We observed a higher rate of blood-culture contamination during the COVID-19 pandemic at our institution compared to a prepandemic period. Given the potential implications of blood contamination in antibiotic and diagnostic test utilization as well as added cost, it is imperative to continue efforts to minimize these episodes during the pandemic.

INTRODUCTION: Staphylococcus aureus bloodstream infections (SABSI) are a major cause of morbidity and mortality in the United States, and proper management is important to effect cure and prevent metastatic foci of infection. We aimed to utilize our antimicrobial stewardship program (ASP) to improve practices at a large academic hospital system. METHODS: Our ASP implemented a SABSI educational campaign directed at the hospital medicine, cardiology, and infectious diseases divisions. A stewardship intervention was then begun for all patients with SABSI recommending infectious diseases consultation, transesophageal echocardiography (TEE), source control, and preliminary antibiotic changes. A retrospective review was performed for all SABSI cases 2 years before and after implementation of the SABSI intervention. RESULTS: Two hundred forty-three cases before intervention and 259 after intervention were included. An increase in obtaining follow-up negative blood cultures (79.8% vs. 89.6%), infectious diseases consultation (52.7% vs. 86.5%), TEE (25.5% vs. 54.8%), beta-lactam switch for methicillin-susceptible S. aureus (55.2% vs. 74.4%), and source control (41.2% vs. 57.9%) was demonstrated. We demonstrated similar durations of bacteremia, length of stay, relapse, mortality, and rates of infective endocarditis. CONCLUSIONS: Adherence to standard of care for patients with SABSI can be dramatically improved through provider education, leveraging antimicrobial stewardship resources, and infectious diseases consultation.

OBJECTIVES: Anti-infective shortages represent a growing threat to optimum management of infected patients and alter the institutional selective pressure against hospital-acquired infections (HAIs). The objective of this analysis was to assess the impact of a shortage of piperacillin/tazobactam (TZP) on overall antibacterial use and HAI rates at an academic institution. METHODS: Antimicrobial use and infection data were extracted from TheraDoc Clinical Surveillance Software (Premier, Inc.) for adult patients and were stratified as pre-shortage (October-December 2014) and post-shortage (February-April 2015). Paediatric and emergency department use were excluded. Antimicrobial use was reported as percent change and defined daily doses (DDD)/1000 patient-days (PD). Pre- and post-shortage vancomycin-resistant enterococci (VRE) and Clostridium difficile-associated diarrhoea (CDAD) rates were normalised to 1000 PD/month. RESULTS: Total use of target antimicrobials remained constant before and after TZP shortage (990.29 vs. 957.77). Total TZP use fell 95.2% (81.1 vs. 3.9). Total meropenem use rose 96.0% (42.3 vs. 82.9) after the shortage, driven by a 125.4% increase in use for non-ICU patients. Cefepime and ceftazidime use rose 97.9% (28.2 vs. 55.8) and 94.2% (1.6 vs 3.0), respectively. Cefepime use in non-ICU patients rose 223.2%. Fluoroquinolone consumption did not differ between periods. CDAD rates decreased (-21.8%), whilst VRE rates doubled during the shortage (0.6 vs. 1.3 infections/1000 PD/month). CONCLUSIONS: Whilst overall antimicrobial use appeared steady, the TZP shortage resulted in increased use of multiple other antimicrobials. The doubling of VRE rates is concerning and illustrates the need for increased antimicrobial stewardship vigilance and education in response to shifting prescribing patterns during shortages.

Ignatzschineria indica is a Gram-negative bacterium that is commonly associated with the larvae of flesh flies. I. indica is difficult to isolate in routine laboratory procedures but has been associated with neglected wounds infested with maggots, fever, elevated white blood count and C-reactive protein, and polymicrobial culture results. Other specific hematological/immunological changes are not known. We present a case of I. indica bacteremia and polymicrobial osteomyelitis resulting from infected decubitus ulcers. The patient improved after treatment with cefepime followed by levofloxacin.
RESUMO
Drug shortages pose a clear detriment to antimicrobial stewardship (AS) efforts. Our objective was to evaluate the effect of a piperacillin-tazobactam shortage on meropenem use, related costs, and associated changes in AS activity. A quasi-experimental quality improvement review compared adult patients receiving meropenem ≥72h three months pre-shortage and three months during the shortage. 320 patients were included (pre-shortage: 103; shortage: 217). Baseline characteristics were similar, but the length of stay was slightly longer in pre-shortage [19 (11-32) days] versus shortage [16 (11-32) days] (p=0.094). In pre-shortage and shortage, median days of therapy and estimated meropenem cost were 7 (5-11) and 7 (5-10) and $309.93 ($173.60-$507.03) and $255.30 ($204.24-$424.31), respectively (p=0.411 and p=0.050). Frequency of ID consultation was similar (16.8% in pre- and 25.3% in shortage, p=0.091). AS interventions increased during the shortage period (99 in pre-shortage and 205 in shortage). De-escalation occurred in 19.4% versus 32.7% of the patients in pre-shortage and shortage (p=0.014). The piperacillin-tazobactam shortage was associated with a 111% increase in meropenem prescriptions despite active AS, but was not associated with changes in mortality, length of therapy, or meropenem costs. AS should be aware that shortages may require proactive countermeasures to avoid inappropriate antimicrobial use during shortage periods.
