ABSTRACT
INTRODUCTION: The first complete long-acting antiretroviral therapy (ART) regimen, cabotegravir + rilpivirine long-acting (CAB + RPV LA) injectable, was approved in the US for HIV-1 treatment in individuals on a stable antiretroviral regimen with a viral load < 50 copies/mL, no treatment failure history, and no resistance to either cabotegravir or rilpivirine. We describe injection schedule adherence and virologic effectiveness of CAB + RPV LA in routine clinical care in the US. METHODS: From the OPERA® cohort, all adults with HIV who received their first CAB + RPV LA injection and ≥ 1 continuation injections between 21 January 2021 and 15 March 2022 were included. The injection target date was updated monthly and set to the same date of the month as the previous injection. Continuation injections administered within 7 days before or after the target date were considered on time, as per the label. Virologic undetectability (viral load < 50 copies/mL), suppression (viral load < 200 copies/mL), and confirmed virologic failure (2 consecutive viral loads ≥ 200 copies/mL or 1 viral load ≥ 200 copies/mL followed by discontinuation) were described among individuals with a viral load < 50 copies/mL at initiation and ≥ 1 follow-up viral load. RESULTS: Among 321 individuals on CAB + RPV LA, 90% of the continuation injections were administered on time (within ± 7 days of the target date). Of the 237 individuals with a viral load < 50 copies/mL at initiation and ≥ 1 follow-up viral load, nearly all were undetectable (95%) or suppressed (99%) at their last viral load measurement, 96% maintained virologic suppression with all measured viral loads < 200 copies/mL, and four confirmed virologic failures were observed. Injection delays were infrequent, and did not affect virologic outcomes over the short term. CONCLUSION: In this large US cohort, most monthly CAB + RPV LA injections were administered on time and high levels of virologic control were achieved. These results suggest that CAB + RPB LA injectable can be administered effectively during routine clinical care.
ABSTRACT
Background: Kidney transplant (KT) candidates have historically low immunization rates against recommended vaccines. A retrospective single-center study of contemporary KT candidates was conducted to assess vaccination rates and vaccine uptake. Methods: All KT candidates ≥18 y evaluated between January 1, 2020, and December 31, 2020, were retrospectively reviewed for history of prior vaccination against tetanus, diphtheria, and pertussis; 13-valent pneumococcal conjugate vaccine; 23-valent pneumococcal polysaccharide vaccine; and recombinant zoster vaccine. Positive hepatitis A IgG total, hepatitis B surface antibody, measles, mumps, rubella, and varicella IgG were assessed as surrogate markers of immunity. Vaccine uptake among vaccine-eligible candidates was also assessed. Results: Among 150 KT candidates, the rate of prior vaccination against tetanus, diphtheria, and pertussis; 13-valent pneumococcal conjugate vaccine; 23-valent pneumococcal polysaccharide vaccine; and recombinant zoster vaccine (latter among patients ≥50 y) was found to be as low as 11%. Hepatitis A IgG total, hepatitis B surface antibody, measles, mumps, rubella, and varicella IgG seropositivity rates were 30%, 66%, 88%, 78%, 90%, and 96%, respectively. Only 7 (5%) of 150 patients had complete immunization or seropositivity. Five (3%) of 143 vaccine-eligible patients declined vaccination. Hepatitis A vaccine declination was relatively common with 15 (16%) of 94 vaccine-eligible patients declining it. Conclusions: KT candidates have low baseline rates of prior immunization/seropositivity against most recommended vaccines. Overall vaccine uptake among eligible candidates was high.
ABSTRACT
Background: Infectious diseases consultation improves outcomes in patients with candidemia, although some facilities lack access to consultation. This multisite health care system study compared in-hospital mortality in patients with candidemia across 3 groups-those who received on-site consultation, telemedicine consultation, or no consultation. All patients were reviewed by an antimicrobial stewardship pharmacist. Methods: A retrospective observational cohort study was performed of adult hospitalized patients with candidemia from January 2018 to October 2021. The primary outcome was in-hospital mortality. Secondary outcomes included receipt and duration of antifungals, removal of central venous lines if present, ophthalmologic examination, echocardiography, and determination of infection source. Results: A total of 265 patients were evaluated: 187 in the on-site consultation group, 49 in the telemedicine consultation group, and 29 in the nonconsultation group. Although in-hospital mortality did not differ significantly between the on-site and nonconsultation groups, it was significantly lower in the telemedicine group when compared with the nonconsultation group (10.2% vs 34.5%, P = .009). Patients who received on-site or telemedicine consultation had significantly more antifungal therapy initiated, appropriate therapy duration, central lines removed, and echocardiography performed, as well as fewer unknown candidemia sources, vs those in the nonconsultation group. Conclusions: This is the first study of a multisite health care system providing telemedicine services to evaluate the impact of infectious diseases consultation on candidemia mortality. These findings suggest that when on-site consultation is unavailable, infectious diseases telemedicine consultation and antimicrobial stewardship can improve outcomes and should be considered for all patients with candidemia at resource-limited sites.
ABSTRACT
Objective: Emerging infectious diseases challenge healthcare systems to implement new models of care. We aim to evaluate the rapid implementation of a new care model for monkeypox in our health system. Design: This is a retrospective case series evaluation under the Reach, Effectiveness, Adoption, Implementation, and Maintenance (RE-AIM) framework of implementation of a testing and care model for monkeypox in a large, integrated health system. Methods: Atrium Health implemented education of providers, testing protocols, and management of potential monkeypox cases using electronic health record (EHR) data capabilities, telehealth, and collaboration between multiple disciplines. The first 4 weeks of care model implementation were evaluated under the RE-AIM framework. Results: One hundred fifty-three patients were tested for monkeypox by 117 unique providers at urgent care, emergency departments, and infectious disease clinics in our healthcare system between 18 July 2022 and 14 August 2022. Fifty-eight monkeypox cases were identified, compared with 198 cases in the state during the time period, a disproportionate number compared with the health system service area, and 52 patients were assessed for need for tecovirimat treatment. The number of tests performed and providers sending tests increased during the study period. Conclusion: Implementation of a dedicated care model leveraging EHR data support, telehealth, and cross-disciplinary collaboration led to more effective identification and management of emerging infectious diseases and is important for public health. Plain Language Summary: Impact of care model implementation on monkeypox New infectious diseases challenge health systems to implement new care practices. Our health system responded to this challenge by implementing a care model for education, testing, and clinical care of monkeypox patients. We analyzed results from implementing the model. We were able to identify a disproportionate number of monkeypox cases compared with the rest of our state by using our model to educate medical providers, encourage testing, and ensure patients had access to best disease care. Implementation of care models for testing and management of new diseases will improve patient care and public health.
ABSTRACT
OBJECTIVES: Our objective was to compare the immunological responses to commonly used antiretroviral therapy (ART) regimens among people with advanced HIV in the USA and to assess virological outcomes and regimen persistence. METHODS: This study included ART-naïve adults with advanced HIV infection (CD4 cell count <200 cells/µL) initiating ART with bictegravir/emtricitabine/tenofovir alafenamide (B/F/TAF), boosted darunavir (bDRV), dolutegravir (DTG), or elvitegravir (EVG/c)-containing regimens between 1 January 2018 and 31 December 2020 in the Observational Pharmaco-Epidemiology Research and Analysis (OPERA) cohort. Cox proportional hazards models and linear mixed models with random intercept were fit with inverse probability of treatment weighting. RESULTS: Overall, 1349 people with advanced HIV (816 B/F/TAF, 253 DTG, 146 EVG/c, 134 bDRV) were followed for a median of 22 months. Compared with B/F/TAF, a lower likelihood of achieving a CD4 cell count ≥200 cells/µL was observed with bDRV (hazard ratio [HR] 0.76; 95% confidence interval [CI] 0.60-0.96), DTG (HR 0.82; 95% CI 0.69-0.98), and EVG/c (HR 0.73; 95% CI 0.57-0.93). All groups had a similar pattern of CD4:CD8 ratio changes: a rapid increase in the first 6 months (ranging from +0.15 to +0.16 units), followed by a slower increase thereafter. Only 40 individuals (4%) achieved CD4:CD8 ratio normalization (≥1). B/F/TAF was associated with a faster time to virological suppression (viral load <200 copies/mL) and a slower time to discontinuation compared with other regimens. CONCLUSIONS: Among people with advanced HIV infection, B/F/TAF initiation was associated with faster CD4 cell count recovery and favourable virological outcomes compared with bDRV-, DTG-, and EVG/c-based regimens, although no difference was observed in CD4:CD8 ratio changes over time across regimens.

BACKGROUND: COVID-19 has disproportionately affected older adults. Frailty has been associated with impaired vaccine response in other vaccine types, but the impact of frailty on mRNA vaccine response is undefined. METHODS: Observational study of adults aged 55 and older from 1 U.S. health care system between January 22, 2021 and September 16, 2021 with self-reported Moderna or Pfizer COVID-19 mRNA vaccine and an electronic frailty index (eFI) score from their medical record (n = 1 677). Participants' frailty status was compared with positive antibody detection (seroconversion) following full vaccination and subsequent loss of positive antibody detection (seroreversion) using logistic regression models. RESULTS: Of 1 677 older adults with median (interquartile range) age, 67 (62 and 72) years, and frailty status (nonfrail: 879 [52%], prefrail: 678 [40%], and frail: 120 [7.2%]), seroconversion was not detected in 23 (1.4%) over 60 days following full vaccination. Frail individuals were less likely to seroconvert than nonfrail individuals, adjusted odds ratio (OR) 3.75, 95% confidence interval (CI; 1.04, 13.5). Seroreversion was detected in 50/1 631 individuals (3.1%) over 6 months of median follow-up antibody testing. Frail individuals were more likely to serorevert than nonfrail individuals, adjusted OR 3.02, 95% CI (1.17, 7.33). CONCLUSION: Overall antibody response to COVID-19 mRNA vaccination was high across age and frailty categories. While antibody detection is an incomplete descriptor of vaccine response, the high sensitivity of this antibody combined with health-system data reinforce our conclusions that frailty is an independent predictor of impaired antibody response to the COVID-19 mRNA vaccines. Frailty should be considered in vaccine studies and prevention strategies.

INTRODUCTION: The COVID-19 Community Research Partnership is a population-based longitudinal syndromic and sero-surveillance study. The study includes over 17,000 participants from six healthcare systems in North Carolina who submitted over 49,000 serology results. The purpose of this study is to use these serology data to estimate the cumulative proportion of the North Carolina population that has either been infected with SARS-CoV-2 or developed a measurable humoral response to vaccination. METHODS: Adult community residents were invited to participate in the study between April 2020 and February 2021. Demographic information was collected and daily symptom screen was completed using a secure, HIPAA-compliant, online portal. A portion of participants were mailed kits containing a lateral flow assay to be used in-home to test for presence of anti-SARS-CoV-2 IgM or IgG antibodies. The cumulative proportion of participants who tested positive at least once during the study was estimated. A standard Cox proportional hazards model was constructed to illustrate the probability of seroconversion over time up to December 20, 2020 (before vaccines available). A separate analysis was performed to describe the influence of vaccines through February 15, 2021. RESULTS: 17,688 participants contributed at least one serology result. 68.7% of the population were female, and 72.2% were between 18 and 59 years of age. The average number of serology results submitted per participant was 3.0 (±1.9). By December 20, 2020, the overall probability of seropositivity in the CCRP population was 32.6%. By February 15, 2021 the probability among healthcare workers and non-healthcare workers was 83% and 49%, respectively. An inflection upward in the probability of seropositivity was demonstrated around the end of December, suggesting an influence of vaccinations, especially for healthcare workers. Among healthcare workers, those in the oldest age category (60+ years) were 38% less likely to have seroconverted by February 15, 2021. CONCLUSIONS: Results of this study suggest more North Carolina residents may have been infected with SARS-CoV-2 than the number of documented cases as determined by positive RNA or antigen tests. The influence of vaccinations on seropositivity among North Carolina residents is also demonstrated. Additional research is needed to fully characterize the impact of seropositivity on immunity and the ultimate course of the pandemic.

BACKGROUND: Approximately 20% of newly diagnosed people with HIV (PWH) in the United States have advanced HIV infection, yet the literature on current antiretroviral therapy (ART) options is limited. The discontinuation/modification and effectiveness of common regimens were compared among ART-naïve people with advanced HIV infection (CD4 cell count <200 cells/µL). METHODS: ART-naïve adults with advanced HIV infection initiating bictegravir/emtricitabine/tenofovir alafenamide (B/F/TAF) or a boosted darunavir (bDRV)-, dolutegravir (DTG)-, or elvitegravir/cobicistat (EVG/c)-based 3-drug regimen between January 1, 2018, and July 31, 2019, in the OPERA cohort were included. The association between regimen and discontinuation or viral suppression (<50 or <200 copies/mL) was assessed using Cox proportional hazards models with inverse probability of treatment weights. RESULTS: Overall, 961 PWH were included (416 B/F/TAF, 106 bDRV, 271 DTG, 168 EVG/c); 70% achieved a CD4 cell count ≥200 cells/µL over a 16-month median follow-up. All regimens were associated with a statistically higher likelihood of discontinuation than B/F/TAF (bDRV: adjusted hazard ratio [aHR], 2.65; 95% CI, 1.75-4.02; DTG: aHR, 2.42; 95% CI, 1.75-3.35; EVG/c: aHR, 3.52; 95% CI, 2.44-5.07). Compared with B/F/TAF, bDRV initiators were statistically less likely to suppress to <50 copies/mL (aHR, 0.72; 95% CI, 0.52-0.99) and <200 copies/mL (aHR, 0.55; 95% CI, 0.43-0.70); no statistically significant difference was detected with DTG or EVG/c. CONCLUSIONS: Among people with advanced HIV infection, those initiating B/F/TAF were less likely to discontinue/modify their regimen than those on any other regimen, and more likely to achieve viral suppression compared with those on bDRV but not compared with those on other integrase inhibitors.
ABSTRACT
OBJECTIVE: To determine the impact of COVID-19 vaccination oninfectionratesin healthcare workers(HCWs) with a householdexposure. METHODS: Retrospectivecohort study8410HCWs(400 fullyvaccinated, 1645partially vaccinated,6365 unvaccinated),employed by a large integrated healthcare system in the southeastern United States,tested for SARS-CoV-2between January 1 and February 26, 2021. RESULTS: Benefit of vaccination persisted even with household exposure, with unvaccinated HCWs being 3.7 to 7.7 times more likely to be infected than partially or fully vaccinated HCW with positive household contacts respectively (partial OR = 3.73, 95% CI 2.17 - 6.47; full OR = 7.67, CI 2.75 - 21.35). Whereas 89.4% of unvaccinated COVID-positive HCWs with known household exposures were symptomatic, 50% of fully vaccinated HCWs had symptoms, reducing risk of secondary spread from and between HCWs. CONCLUSIONS: COVID-19vaccinationprovided protection against infection evenamongst healthcare workerswithclose household contact,and after adjusting for community prevalence.

OBJECTIVES: To evaluate whether a nurse navigator-led, multicomponent Sepsis Transition And Recovery program improves 30-day mortality and readmission outcomes after sepsis hospitalization. DESIG: n: Multisite pragmatic randomized clinical trial. SETTING: Three hospitals in North Carolina from January 2019 to March 2020. PATIENTS: Eligible patients hospitalized for suspected sepsis and deemed high-risk for mortality or readmission by validated internal risk models. INTERVENTIONS: Patients were randomized to receive usual care alone (i.e., routine transition support, outpatient care; n = 342) or additional Sepsis Transition And Recovery support (n = 349). The 30-day intervention involved a multicomponent transition service led by a nurse navigator through telephone and electronic health record communication to facilitate best practice postsepsis care strategies during and after hospitalization including: postdischarge medication review, evaluation for new impairments or symptoms, monitoring comorbidities, and palliative care approach when appropriate. Clinical oversight was provided by a Hospital Medicine Transition Services team. MEASUREMENTS AND MAIN RESULTS: The primary outcome was a composite of mortality or hospital readmission at 30 days. Logistic regression models were constructed to evaluate marginal and conditional odds ratios (adjusted for prognostic covariates: age, comorbidity, and organ dysfunction at enrollment). Among 691 randomized patients (mean age = 63.7 ± 15.1 yr; 52% female), a lower percentage of patients in the Sepsis Transition And Recovery group experienced the primary outcome compared with the usual care group (28.7% vs 33.3%; risk difference, 4.7%; odds ratio, 0.80; 95% CI, 0.58-1.11; adjusted odds ratio, 0.80; 95% CI, 0.64-0.98). There were 74 deaths (Sepsis Transition And Recovery: 33 [9.5%] vs usual care: 41 [12.0%]) and 155 rehospitalizations (Sepsis Transition And Recovery: 71 [20.3%] vs usual care: 84 [24.6%]). CONCLUSIONS: In a multisite randomized clinical trial of patients hospitalized with sepsis, patients provided with a 30-day program using a nurse navigator to provide best practices for postsepsis care experienced a lower proportion of either mortality or rehospitalization within 30 days after discharge. Further research is needed to understand the contextual factors associated with successful implementation.

Background: Access to SARS-CoV-2 testing is a crucial component of early identification and disease containment. Racial and ethnic health disparities exist related to testing utilization. To optimize testing with limited resources, Atrium Health developed free-standing and roving testing centers outside of the traditional clinical settings in hopes of meeting the needs of a diverse urban community. The objective of this study is to evaluate differences in testing site utilization based on demographic factors, particularly race/ethnicity. Methods:A cohort study of patients tested for COVID-19 between March 10 and October 26, 2020, within the Atrium Health system. Results: 128,258 persons under investigation (PUIs) were tested across our health system, including 25,434 patients at our Mobile Integrated Health (previously called Community Paramedicine) drive-thru testing sites and community roving testing units. PUIs were on average 47 years old (SD = 17.7); approximately half were female and White/Caucasian. Drive-thru testing sites were utilized proportionally more by non-Hispanic Whites and African Americans, and less by Hispanic PUIs. Roving testing units were used significantly more by younger PUIs, Hispanics, and PUIs of other races/ethnicities. Conclusions: Diversification in testing site locations optimized testing resources, allowed for significant reduction in the burden of patient volumes, and avoided alteration of workflow in our urgent care facilities and Emergency Departments. Additionally, roving testing units may help to decrease racial/ethnic disparities in access to COVID-19 testing. Our results highlight the importance of offering a variety of testing modalities to reach different populations.
ABSTRACT
BACKGROUND: Sepsis survivors experience high morbidity and mortality, and healthcare systems lack effective strategies to address patient needs after hospital discharge. The Sepsis Transition and Recovery (STAR) program is a navigator-led, telehealth-based multicomponent strategy to provide proactive care coordination and monitoring of high-risk patients using evidence-driven, post-sepsis care tasks. The purpose of this study is to evaluate the effectiveness of STAR to improve outcomes for sepsis patients and to examine contextual factors that influence STAR implementation. METHODS: This study uses a hybrid type I effectiveness-implementation design to concurrently test clinical effectiveness and gather implementation data. The effectiveness evaluation is a two-arm, pragmatic, stepped-wedge cluster randomized controlled trial at eight hospitals in North Carolina comparing clinical outcomes between sepsis survivors who receive Usual Care versus care delivered through STAR. Each hospital begins in a Usual Care control phase and transitions to STAR in a randomly assigned sequence (one every 4 months). During months that a hospital is allocated to Usual Care, all eligible patients will receive usual care. Once a hospital transitions to STAR, all eligible patients will receive STAR during their hospitalization and extending through 90 days from discharge. STAR includes centrally located nurse navigators using telephonic counseling and electronic health record-based support to facilitate best-practice post-sepsis care strategies including post-discharge review of medications, evaluation for new impairments or symptoms, monitoring existing comorbidities, and palliative care referral when appropriate. Adults admitted with suspected sepsis, defined by clinical criteria for infection and organ failure, are included. Planned enrollment is 4032 patients during a 36-month period. The primary effectiveness outcome is the composite of all-cause hospital readmission or mortality within 90 days of discharge. A mixed-methods implementation evaluation will be conducted before, during, and after STAR implementation. DISCUSSION: This pragmatic evaluation will test the effectiveness of STAR to reduce combined hospital readmissions and mortality, while identifying key implementation factors. Results will provide practical information to advance understanding of how to integrate post-sepsis management across care settings and facilitate implementation, dissemination, and sustained utilization of best-practice post-sepsis management strategies in other heterogeneous healthcare delivery systems.

BACKGROUND: Telemedicine (TM) programs can be implemented to deliver specialty care through virtual platforms and overcome geographic/resource constraints. Few data exist to describe outcomes associated with TM-based infectious diseases (ID) management. The purpose of this study was to compare outcomes associated with TM and onsite standard-of-care (SOC) ID consultation after implementation of an antimicrobial stewardship (AMS)-led Staphylococcus aureus bacteremia (SAB) bundle. METHODS: A retrospective cohort study was conducted on the effects of a SAB bundle comparing ID consult delivery (SOC or TM) at 10 US hospitals within Atrium Health in adult patients admitted from September 2016 through December 2017. The type of ID consult provided was based on the admitting hospital; no hospital had both modalities. Bundle components included the following: (1) ID consult, (2) appropriate antibiotics, (3) repeat blood cultures until clearance, (4) echocardiogram obtainment, and (5) appropriate antibiotic duration. The AMS facilitated bundle initiation and compliance. The primary outcome was bundle adherence between groups. Differences in clinical outcomes were also assessed. RESULTS: We evaluated 738 patients with SAB (576 with SOC, 162 with TM ID). No differences were observed in overall bundle adherence (SOC 86% vs TM 89%, P = .33). In addition, no significant differences resulted between groups for hospital mortality, 30-day SAB-related readmission, persistent bacteremia, and culture clearance. Groups did not differ in 30-day mortality when controlling for demographics, bacteremia source, and physiological measures with multivariable logistic regression. CONCLUSIONS: Our findings provide evidence to support effective use of TM ID consultation and AMS-led care bundles for SAB management in resource-limited settings.
ABSTRACT
The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic has revolutionized the practice of ambulatory medicine, triggering rapid dissemination of digital healthcare modalities, including synchronous video visits. However, social determinants of health, such as age, race, income, and others, predict readiness for telemedicine and individuals who are not able to connect virtually may become lost to care. This is particularly relevant to the practice of infectious diseases (ID) and human immunodeficiency virus (HIV) medicine, as we care for high proportions of individuals whose health outcomes are affected by such factors. Furthermore, delivering high-quality clinical care in ID and HIV practice necessitates discussion of sensitive topics, which is challenging over video without proper preparation. We describe the "digital divide," emphasize the relevance to ID and HIV practice, underscore the need to study the issue and develop interventions to mitigate its impact, and provide suggestions for optimizing telemedicine in ID and HIV clinics.

We report a case of disseminated histoplasmosis in a renal transplant recipient who presented with a nodular pulmonary lesion and elevated serum and bronchoalveolar lavage (BAL) Aspergillus galatomannan. This almost led to an erroneous diagnosis of invasive aspergillosis since the donor respiratory tract was known to be colonized with Aspergillus terreus. However, distinctive intracelluar Histoplasma yeasts on peripheral blood smear led to early diagnosis and appropriate treatment. The cross-reactivity between Aspergillus galactomannan and Histoplasma antigen is discussed further.

Over the last 2 decades, telemedicine has effectively demonstrated its ability to increase access to care. This access has the ability to deliver quality clinical care and offer potential savings to the healthcare system. With increasing frequency, physicians, clinics, and medical centers are harnessing modern telecommunications technologies to manage a multitude of acute and chronic conditions, as well as incorporating telehealth into teaching and research. The technologies spanning telehealth, telemedicine, and mobile health (mHealth) are rapidly evolving, and the Infectious Diseases Society of America (IDSA) has prepared this updated position statement to educate its membership on the use of telemedicine and telehealth technologies. IDSA supports the appropriate and evidence-based use of telehealth technologies to provide up-to-date, timely, cost-effective subspecialty care to resource-limited populations.

BACKGROUND: Acute bacterial skin and skin structure infections (ABSSSI) are a leading cause of hospitalization, but are often treated inappropriately in the inpatient setting. A multifaceted stewardship intervention was implemented to encourage prescribing of guideline-concordant therapy (GCT). OBJECTIVE: To examine the impact of this initiative on antimicrobial prescribing practices and patient outcomes. METHODS: This was a single-center, retrospective study of adult inpatients admitted with a primary or secondary diagnosis of ABSSSI, classified by type and severity based on signs of systemic infection. Patients treated during the pre-intervention period (pre-IP) were compared with patients treated during the post-intervention period (post-IP). The primary endpoint was receipt of GCT. Secondary endpoints included receipt of anti-anaerobic antibiotic (AAA) or broad-spectrum antibiotics (BSA). RESULTS: A total of 125 patients were included, 64 in the pre-IP and 61 in the post-IP. There was a statistically significant increase in prescribing of GCT during the post-IP compared with the pre-IP (14% versus 56%, p < 0.0001) and a decrease in use of AAA (56% versus 34%, p = 0.01). No difference was observed with use of BSA (16% versus 15%, p = 0.89). Use of the computerized order set during the post-IP was low (18%). There was a numerical, but non-significant reduction in 30-day readmission (14.1% versus 6.6%, p = 0.17). CONCLUSION: The multifaceted intervention was effective for improving prescribing of GCT for ABSSSI. Given low use of the computerized order set, improved prescribing seemed to be driven by provider education. Strategies around ongoing education may be key to sustain positive results of stewardship interventions.
ABSTRACT
BACKGROUND: Outpatient parenteral antimicrobial therapy (OPAT) prescribing has increased along with the trend toward early discharge of hospitalized patients who have infections. There is limited literature that assesses unplanned hospitalizations during OPAT. This study aims to elucidate the predictors of unplanned hospitalization in OPAT patients after discharge from acute-care facilities within Carolinas HealthCare System (CHS). Understanding these predictors may inform future interventions to improve treatment efficacy and patient outcomes. METHODS: The study cohort included hospitalized patients aged >19 years who initiated OPAT in an acute-care facility within CHS in 2014-2015. Patients who had OPAT prescribed at an ambulatory-care facility were excluded. The primary outcome was unplanned hospitalization anytime during the at-risk time from discharge through 90 days. RESULTS: The unplanned hospitalization rate for the cohort was 18.5%. In adjusted analysis, having OPAT delivered at a skilled nursing facility was associated with a 46% (incident risk ratio = 1.46; 95% confidence interval = 1.04-2.06) increased risk of an unplanned hospitalization compared with patients receiving OPAT at home after adjustment for demographics, comorbidities, indication, treatment duration, and antimicrobial prescribed. Infusion, dialysis, and rehabilitation centers had the lowest rates of unplanned hospitalizations. CONCLUSIONS: These results suggest that the location of OPAT delivery is associated with unplanned hospitalizations and that older patients need additional support during OPAT.
ABSTRACT
PURPOSE: To determine if treating bronchoalveolar lavage (BAL) culture-positive patients with antifungal therapy impacted mortality compared to not treating due to presumed colonization. METHODS: We conducted a retrospective study of immunocompetent, critically ill adult patients from 2010 to 2014. Patients with a BAL culture-positive for Candida or unspeciated yeast and a clinical suspicion of pneumonia were included. The treatment group received an antifungal agent for at least 5 days, and the control group received either no antifungal therapy or an antifungal agent for less than 48 h. Recruitment occurred in a 2:1 ratio of untreated versus treated patients. RESULTS: Seventy-five patients were included. In-hospital mortality was similar between treated and untreated groups (24% vs. 26%, P = 0.85). Length of stay and duration of mechanical ventilation also did not differ between the two groups. CONCLUSION: We did not observe a difference in mortality or clinical outcomes in patients treated with antifungal agents. Presumptive antifungal therapy for BAL-positive Candida or yeast in immunocompetent patients did not result in improved clinical outcomes.
