Fixing a Hole: a retrospective cohort study evaluating HAV, HBV, tetanus screening, and vaccination during hospitalization in persons who use substances.

Background: Rates of serious injection-related infections in persons who use drugs have increased. Resulting admissions are an opportunity for screening and vaccination of preventable infections such as hepatitis A virus (HAV), hepatitis B virus (HBV), and tetanus. Design and methods: We conducted a retrospective review of adults with documented substance use admitted for bacterial infection between July 2015 and March 2020. We evaluated HAV, HBV, and tetanus vaccination status at admission, along with screening for HAV and HBV infection and immunity. We identified the proportion of patients at risk for infection who received HAV, HBV, and tetanus vaccines during admission and patient-level factors associated with vaccination. Results: We identified 280 patients who met our inclusion criteria. Of the 198 (70.7%) patients at risk for HAV, infectious disease providers recommended vaccination for 21 (10.6%) and 15 (7.6%) received HAV vaccine. Of the 174 (62.1%) patients at risk for HBV, infectious disease providers recommended vaccination for 32 (18.3%) and 25 (14.4%) received HBV vaccine. A large proportion of patients (31.4%, 88) had no documentation of prior tetanus vaccination, and infectious disease providers recommended tetanus vaccination for three (1.1%) and five patients (1.8%) received a tetanus booster. Infectious disease consult vaccine recommendations were statistically significantly associated with HAV or HBV vaccination prior to discharge. Conclusion: Over 70% of our population is at risk for one or more of these preventable infections. Efforts are needed to maximize inpatient screening and vaccination for HAV, HBV, and tetanus in patients with barriers to care.

Dalba Got Back? Use of Dalbavancin for the Treatment of Vertebral Osteomyelitis.

Data evaluating dalbavancin use for vertebral osteomyelitis remain limited. In our retrospective cohort, 29 of 34 (85.3%) patients completed their dalbavancin course. Adverse reactions occurred for 6 (17.6%) and infection recurrence in 3 (8.8%) within 90 days. Dalbavancin appears to be safe and well-tolerated for vertebral osteomyelitis.

"I know my body better than anyone else": a qualitative study of perspectives of people with lived experience on antimicrobial treatment decisions for injection drug use-associated infections.

Background: People who inject drugs (PWID) are at risk for severe bacterial and fungal infections including skin and soft tissue infections, endocarditis, and osteomyelitis. PWID have high rates of self-directed discharge and are often not offered outpatient antimicrobial therapies, despite studies showing their efficacy and safety in PWID. This study fills a gap in knowledge of patient and community partner perspectives on treatment and discharge decision making for injection drug use (IDU)-associated infections. Methods: We conducted semi-structured interviews with patients (n = 10) hospitalized with IDU-associated infections and community partners (n = 6) in the Portland, Maine region. Community partners include peer support workers at syringe services programs (SSPs) and outreach specialists working with PWID. We transcribed and thematically analyzed interviews to explore perspectives on three domains: perspectives on long-term hospitalization, outpatient treatment options, and patient involvement in decision making. Results: Participants noted that stigma and inadequate pain management created poor hospitalization experiences that contributed to self-directed discharge. On the other hand, patients reported hospitalization provided opportunities to connect to substance use disorder (SUD) treatment and protect them from outside substance use triggers. Many patients expressed interest in outpatient antimicrobial treatment options conditional upon perceived efficacy of the treatment, perceived ability to complete treatment, and available resources and social support. Finally, both patients and community partners emphasized the importance of autonomy and inclusion in medical decision making. Although some participants acknowledged their SUD, withdrawal symptoms, or undertreated pain might interfere with decision making, they felt these medical conditions were not justification for health care professionals withholding treatment options. They recommended open communication to build trust and reduce harms. Conclusion: Patients with IDU-associated infections desire autonomy, respect, and patient-centered care from healthcare workers, and may self-discharge when needs or preferences are not met. Involving patients in treatment decisions and offering outpatient antimicrobial options may result in better outcomes. However, patient involvement in decision making may be complicated by many contextual factors unique to each patient, suggesting a need for shared decision making to meet the needs of hospitalized patients with IDU-associated infections.

The hidden cost of dalbavancin: OPAT RN time required in coordination for persons who use drugs.

Background: Serious infections in persons who use drugs (PWUD) are rising. Dalbavancin, due to its extended half-life, offers an alternative treatment for patients in whom standard of care antibiotics are not feasible or practical, allowing for reduced hospital days and the avoidance of central line placement or the use of complex oral regimens. Objectives: We aim to describe the time and effort required for coordination of dalbavancin courses by outpatient registered nurses (RNs) and other outpatient parenteral antimicrobial therapy (OPAT) staff. Design and methods: We conducted a retrospective review of adult patients with documented substance use who received at least one dose of dalbavancin and quantified the number of interventions required by our OPAT RNs and other OPAT staff for coordination of dalbavancin courses. Additionally, detailed data on time spent per intervention were prospectively collected for a 1-month period. Results: A total of 52 patients with 53 dalbavancin courses were included. Most substance use was intravenous. Infectious diagnoses included bone and joint infections (61%) and endocarditis (7%), in addition to skin and soft tissue infections (19%). Infections were most commonly caused by Staphylococcus aureus (62%). RN intervention was required in the coordination of 60% of all courses and in 77% of courses in which at least one outpatient dose was needed. Adverse reactions occurred in one patient (2%) and 90-day readmissions due to infectious complications occurred in two patients (4%). Detailed time analysis was performed for seven consecutive patients, with a total of 179 min spent by OPAT RNs on coordination. Conclusions: The ease of dalbavancin administration does not eliminate the need for extensive RN coordination for successful administration of doses in the outpatient setting for PWUD. This need should be accounted for in program staffing to help increase successful dalbavancin course completion.

Perspectives on the Use of Outpatient Parenteral Antibiotic Therapy for People who Inject Drugs: Results From an Online Survey of Infectious Diseases Clinicians.

Injection-related infections require prolonged antibiotic therapy. Outpatient parenteral antimicrobial therapy (OPAT) has been shown to be feasible for people who inject drugs (PWID) in some settings. We report a national survey on practice patterns and attitudes of infectious diseases clinicians in the United States regarding use of OPAT for PWID.

Incidence and risk factors for clinically confirmed secondary bacterial infections in patients hospitalized for coronavirus disease 2019 (COVID-19).

OBJECTIVE: The true incidence and risk factors for secondary bacterial infections in coronavirus disease 2019 (COVID-19) remains poorly understood. Knowledge of risk factors for secondary infections in hospitalized patients with COVID-19 is necessary to optimally guide selective use of empiric antimicrobial therapy. DESIGN: Single-center retrospective cohort study of symptomatic inpatients admitted for COVID-19 from April 15, 2020, through June 30, 2021. SETTING: Academic quaternary-care referral center in Portland, Oregon. PATIENTS: The study included patients who were 18 years or older with a positive severe acute respiratory coronavirus virus 2 (SARS-CoV-2) PCR test up to 10 days prior to admission. METHODS: Secondary infections were identified based on clinical, radiographic, and microbiologic data. Logistic regression was used to identify risk factors for secondary infection. We also assessed mortality, length of stay, and empiric antibiotics among those with and without secondary infections. RESULTS: We identified 118 patients for inclusion; 31 (26.3%) had either culture-proven or possible secondary infections among hospitalized patients with COVID-19. Mortality was higher among patients with secondary infections (35.5%) compared to those without secondary infection (4.6%). Empiric antibiotic use on admission was high in both the secondary and no secondary infection groups at 71.0% and 48.3%, respectively. CONCLUSIONS: The incidence of secondary bacterial infection was moderate among hospitalized patients with COVID-19. However, a higher proportion of patients received empiric antibiotics regardless of an identifiable secondary infection. Transfer from an outside hospital, baseline immunosuppressant use, and corticosteroid treatment were independent risk factors for secondary infection. Additional studies are needed to validate risk factors and best guide antimicrobial stewardship efforts.

'I feel like they're actually listening to me': a pilot study of a hospital discharge decision-making conversation guide for patients with injection drug use-associated infections.

Background: The prevalence of injection drug use (IDU)-associated infections and associated hospitalizations has been increasing for nearly two decades. Due to issues ranging from ongoing substance use to peripherally inserted central catheter safety, many clinicians find discharge decision-making challenging. Typically, clinicians advise patients to remain hospitalized for several weeks for intravenous antimicrobial treatment; however, some patients may desire other antimicrobial treatment options. A structured conversation guide, delivered by infectious disease physicians, intended to inform hospital discharge decisions has the potential to enhance patient participation in decisions. We developed a conversation guide in order to: (1) investigate its feasibility and acceptability and (2) examine experiences, outcomes, and lessons learned from use of the guide. Methods: We interviewed physicians after they each piloted the conversation guide with two patients. We interviewed patients immediately after the conversation and again 4-6 weeks later. Two analysts indexed transcriptions and used the framework method to identify and organize relevant information. We conducted retrospective chart review to corroborate and contextualize qualitative data. Results: Eight patients and four infectious disease physicians piloted the conversation guide. All patients (N = 8) completed antimicrobial treatment. Nearly all participants believed the conversation guide was important for incorporating patient values and preferences. Patients reported an increased sense of autonomy, but felt post-discharge needs could be better addressed. Physician participants identified the guide's long length and inclusion of pain management as areas for improvement. Conclusions: A novel conversation guide to inform hospital discharge decision-making for patients with IDU-associated infections was feasible, acceptable, and fostered the incorporation of patient preferences and values into decisions. While we identified areas for improvement, overall participants believed that this novel conversation guide helped to improve patient care and autonomy.

Decreased hospital readmissions after programmatic strengthening of an outpatient parenteral antimicrobial therapy (OPAT) program.

Objective: To determine whether a structured OPAT program supervised by an infectious disease physician and led by an OPAT nurse decreased hospital readmission rates and OPAT-related complications and whether it affected clinical cure. We also evaluated predictors of readmission while receiving OPAT. Patients: A convenience sample of 428 patients admitted to a tertiary-care hospital in Chicago, Illinois, with infections requiring intravenous antibiotic therapy after hospital discharge. Methods: In this retrospective, quasi-experimental study, we compared patients discharged on intravenous antimicrobials from an OPAT program before and after implementation of a structured ID physician and nurse-led OPAT program. The preintervention group consisted of patients discharged on OPAT managed by individual physicians without central program oversight or nurse care coordination. All-cause and OPAT-related readmissions were compared using the χ2 test. Factors associated with readmission for OPAT-related problems at a significance level of P < .10 in univariate analysis were eligible for testing in a forward, stepwise, multinomial, logistic regression to identify independent predictors of readmission. Results: In total, 428 patients were included in the study. Unplanned OPAT-related hospital readmissions decreased significantly after implementation of the structured OPAT program (17.8% vs 7%; P = .003). OPAT-related readmission reasons included infection recurrence or progression (53%), adverse drug reaction (26%), or line-associated issues (21%). Independent predictors of hospital readmission due to OPAT-related events included vancomycin administration and longer length of outpatient therapy. Clinical cure increased from 69.8% before the intervention to 94.9% after the intervention (P < .001). Conclusion: A structured ID physician and nurse-led OPAT program was associated with a decrease in OPAT-related readmissions and improved clinical cure.

Human MPox (Monkeypox) Virus Membranous Keratoconjunctivitis With Transient Corneal Hypoesthesia and Late Symblepharon Formation: A Novel Case and Clinical Implications.

PURPOSE: The aim of this study was to describe a case of corneal involvement as an early manifestation of ocular disease in the 2022 human mpox (monkeypox) virus outbreak. METHODS: This is a single case report with longitudinal care. RESULTS: A 47-year-old immunocompetent man presented with viral conjunctivitis before development of skin lesions or systemic symptoms. Subsequently, he developed membranous keratoconjunctivitis and a corneal epithelial defect. Orthopoxvirus-positive polymerase chain reaction test from his ocular surface was positive. The epithelial defect did not heal with conservative treatment but was successfully treated with amniotic membrane transplantation over 8 days. Reduced corneal sensation was noted after epithelial healing, and polymerase chain reaction from the ocular surface remained positive at 17 days from symptom onset, with slowly recovering conjunctivitis at 21 days. Continued membrane formation required repeated removal but significantly improved with topical corticosteroid treatment after epithelial healing by 29 days of symptom onset. Corneal sensation normalized by 87 days from symptom onset at which time symblepharon were noted but PCR testing from the ocular surface was negative. CONCLUSIONS: Early corneal involvement of human monkeypox virus is possible. Transient corneal hypoesthesia may be due to acute inflammation. Chronic inflammatory changes can result in symblepharon. These findings have potential implications in patient care and corneal donation.

Evaluation of Opportunities for Oral Antibiotic Therapy in Bone and Joint Infections.

BACKGROUND: The OVIVA trial suggests oral antibiotics are an alternative to intravenous antibiotics to treat bone and joint infections (BJI). A shift in practice to treatment with oral antibiotics would eliminate the need for central vascular access, improve patient satisfaction, and reduce overall healthcare costs. OBJECTIVE: The primary objective was to identify the proportion of patients treated for BJIs with outpatient parenteral antimicrobial therapy (OPAT) who would have qualified for oral antibiotics based on microbiological data. The secondary objective was to conduct a cost-analysis to estimate potential cost-savings had eligible patients been treated with oral antibiotics. METHODS: This was a single-center, retrospective study of adult patients in the United States treated with intravenous antibiotics for BJIs from January 2018 to April 2020. Inclusion and exclusion criteria matched the OVIVA trial. Patients with Staphylococcus aureus bacteremia, endocarditis, or other high-risk features were excluded. RESULTS: 281 patients met the inclusion criteria. Most had prosthetic joint infections (56%). Infections caused by coagulase-negative staphylococci (25%) were most common, followed by S. aureus (23%) and polymicrobial infections (22%). 69 (25%) patients required a switch during their OPAT course to an alternate antibiotic agent. Thirteen patients (5%) experienced vascular access complications, and 6 patients (2%) developed Clostridiodes difficile infections. Oral therapy could have resulted in an estimated average savings per patient of $3,270.69 USD. CONCLUSION AND RELEVANCE: Most patients treated with OPAT for BJIs were candidates for oral antibiotics. A change in practice would result in cost-savings to the U.S. healthcare system.

Health care professional perspectives on discharging hospitalized patients with injection drug use-associated infections.

Background: Patients with injection drug use (IDU)-associated infections traditionally experience prolonged hospitalizations, which often result in negative experiences and bad outcomes. Harm reduction approaches that value patient autonomy and shared decision-making regarding outpatient treatment options may improve outcomes. We sought to identify health care professionals (HCPs) perspectives on the barriers to offering four different options to hospitalized people who use drugs (PWUD): long-term hospitalization, oral antibiotics, long-acting antibiotics at an infusion center, and outpatient parenteral antibiotics. Methods: We recruited HCPs (n = 19) from a single tertiary care center in Portland, Maine. We interviewed HCPs involved with discharge decision-making and other HCPs involved in the specialized care of PWUD. Semi-structured interviews elicited lead HCP values, preferences, and concerns about presenting outpatient antimicrobial treatment options to PWUD, while support HCPs provided contextual information. We used the iterative categorization approach to code and thematically analyze transcripts. Results: HCPs were willing to present outpatient treatment options for patients with IDU-associated infections, yet several factors contributed to reluctance. First, insufficient resources, such as transportation, may make these options impractical. However, HCPs may be unaware of existing community resources or viable treatment options. They also may believe the hospital protects patients, and that discharging patients into the community exposes them to structural harms. Some HCPs are concerned that patients with substance use disorder will not make 'good' decisions regarding outpatient antimicrobial options. Finally, there is uncertainty about how responsibility for offering outpatient treatment is shared across changing care teams. Conclusion: HCPs perceive many barriers to offering outpatient care for people with IDU-associated infections, but with appropriate interventions to address their concerns, may be open to considering more options. This study provides important insights and contextual information that can help inform specific harm reduction interventions aimed at improving care of people with IDU-associated infections.

Screening for co-infections in patients with substance use disorders and severe bacterial infections.

Background: Patients with substance use disorders admitted for severe bacterial infection are in a prime position to be screened for important co-infections. However, data suggest that standard screening for co-infections in this population during hospital admission can vary in frequency and type of testing. Methods: We performed a retrospective review of patients to evaluate screening for co-infections during admission, followed by a case-control analysis to determine factors associated with lack of any screening. Results: We identified 280 patients with 320 eligible admissions. Most were male and Caucasian with unstable housing. Only 67 (23.9%) patients had a primary-care provider. About 89% (n = 250) of our cohort were screened for one or more co-infection during their first admission with one patient never screened despite subsequent admissions. Of those screened, the greatest proportion was HIV (219, 81.4% of those without history of HIV), HCV (94, 79.7% of those without a prior positive HCV antibody), syphilis (206, 73.6%), gonorrhea, and chlamydia (47, 16.8%) with new positive tests identified in 60 (21.4%) people. Screening for all five co-infections was only completed in 15 (14.0%) of the 107 patients who had screening indications. Overall, a high proportion of those screened had a new positive test, including three cases of neurosyphilis, highlighting the importance of screening and treatment initiation. One patient was prescribed HIV pre-exposure prophylaxis at discharge and only 37 (34.6%) of those eligible were referred for HCV treatment or follow-up. In multivariable case-control analysis, non-Medicaid insurance (OR 2.8, 95% CI: 1.2-6.6, p = 0.02), use of only 1 substance (OR 2.9, 95% CI: 1.3-6.5, p < 0.01), and no documented screening recommendations by the infectious disease team (OR 3.7, 95% CI: 1.5-8.8, p < 0.01), were statistically significantly associated with lack of screening for any co-infection during hospital admission. Conclusion: Our data suggest additional interventions are needed to improve inpatient screening for co-infections in this population.

Description and outcomes of patients with substance use disorder with serious bacterial infections who had a multidisciplinary care conference.

Background: Patients with substance use disorders (SUDs) and severe bacterial infections requiring prolonged antibiotic therapy represent a significant challenge to providers due to complexity of care coordination required to ensure safe and effective treatment. Our institution developed a patient-centered multidisciplinary discharge planning conference, OPTIONS-DC, to address this challenge. Methods: We conducted a retrospective review to evaluates parameters between patients who received an OPTIONS-DC and those who did not. Results: We identified 73 patients receiving an OPTIONS-DC and 100 who did not. More patients with an OPTIONS-DC were < 40 years of age (76.7% versus 61.0%, OR = 2.3, 95% CI = 1.1-4.7, p = 0.02), had positive HCV antibody testing (58.9% versus 41.0%, OR = 2.1, 95% CI = 1.1-3.8, p = 0.02), injection drug use (93.2% versus 79.0%, OR = 3.6 95% CI = 1.3-10.1, p = 0.01), used methamphetamines (84.9% versus 72.0%, OR = 2.2, 95% CI = 1.0-4.8, p = 0.04), and started inpatient SUD treatment (80.8% versus 63%, OR = 2.5, 95% CI = 1.2-5.0, p = 0.04) compared with those without a conference. The OPTIONS-DC group was more likely to be diagnosed with bacteremia (74.0% versus 57.0%, OR = 2.1, 95% CI = 1.1-4.1, p = 0.02), endocarditis (39.7% versus21.0%, OR = 2.5, 95% CI = 1.3-4.9, p = 0.03), vertebral osteomyelitis (45.2% versus 15.0%, OR = 4.7, 95% CI = 2.3-9.6, p < 0.01), and epidural abscess (35.6% versus 10.0%, OR = 5.0, 95% CI = 2.2-11.2, p < 0.01) and require 4 weeks or more of antibiotic treatment (97.3% versus 51.1%, OR = 34.1, 95% CI = 7.9-146.7, p = 0.01). Patients with an OPTIONS-DC were also more likely to be admitted between 2019 and 2020 than between 2018 and 2019 (OR = 4.1, 95% CI = 2.1-7.9, p < 0.01). Conclusion: Patients with an OPTIONS-DC tended to have more complicated infections and longer courses of antibiotic treatment. While further research on outcomes is needed, patients receiving an OPTIONS-DC were able to successfully complete antibiotic courses across a variety of settings.

The challenge of antibiotic selection in prosthetic joint infections due to Corynebacterium striatum: a case report.

BACKGROUND: Corynebacterium striatum is a gram-positive facultative anaerobe found in the environment and human flora that has historically been considered a contaminant. More recently, Corynebacterium striatum has been implicated in human infections, including respiratory infections, endocarditis, and bone and joint infections, particularly those involving hardware or implanted devices. CASE PRESENTATION: A 65-year-old man presented for washout of his left total knee arthroplasty following a revision 20 days prior. The patient underwent debridement of his left total knee and revision of the left total femur arthroplasty. Daptomycin was initiated empirically due to a previous rash from vancomycin. Operative tissue cultures grew Staphylococcus haemolyticus, Staphylococcus epidermidis and Corynebacterium striatum. Given concern for daptomycin resistance and the reliability of vancomycin susceptibility, daptomycin was discontinued and vancomycin initiated following a graded challenge. Within a few days, the patient developed a diffuse, blanching, erythematous, maculopapular rash and daptomycin was restarted. Over the next 72 h, his rash progressed and he met criteria for drug reaction with eosinophilia and systemic symptoms (DRESS) syndrome. Daptomycin was stopped and oral linezolid initiated; rash improved. C. striatum returned with susceptibility to gentamicin, linezolid, vancomycin and daptomycin. Due to concern for adverse effects on long-term linezolid, daptomycin was restarted and was tolerated for 20 days, at which point purulent drainage from incision increased. The patient underwent another arthroplasty revision and washout. Operative cultures from this surgery were again positive for C. striatum. Repeat C. striatum susceptibilities revealed resistance to daptomycin but retained susceptibility to linezolid. Daptomycin was again changed to linezolid. He completed six weeks of linezolid followed by linezolid 600 mg daily for suppression and ultimately opted for disarticulation. CONCLUSIONS: C. striatum has historically been regarded as a contaminant, particularly when grown in tissue culture in the setting of prosthetic joint infection. Based on the available literature and susceptibility patterns, the most appropriate first-line therapy is vancomycin or linezolid. Treatment with daptomycin should be avoided, even when isolates appear susceptible, due to the risk of development of high-level resistance (MIC > 256 µg/mL) and clinical failure.

"OPTIONS-DC", a feasible discharge planning conference to expand infection treatment options for people with substance use disorder.

BACKGROUND: Serious bacterial infections associated with substance use often result in long hospitalizations, premature discharges, and high costs. Out-of-hospital treatment options in people with substance use disorder (SUD) are often limited. METHODS: We describe a novel multidisciplinary and interprofessional care conference, "OPTIONS-DC," to identify treatment options agreeable to both patients and providers using the frameworks of harm reduction and patient-centered care. We retrospectively reviewed charts of patients who had an OPTIONS-DC between February 2018 and July 2019 and used content analysis to understand the conferences' effects on antibiotic treatment options. RESULTS: Fifty patients had an OPTIONS-DC during the study window. Forty-two (84%) had some intravenous (IV) substance use and 44 (88%) had an active substance use disorder. Participants' primary substances included opioids (65%) or methamphetamines (28%). On average, conferences lasted 28 min. OPTIONS-DC providers recommended out-of-hospital antibiotic treatment options for 34 (68%) of patients. OPTIONS-DC recommended first line therapy of IV antibiotics for 35 (70%) patients, long-acting injectable antibiotics for 14 (28%), and oral therapy for 1 (2%). 35 (70%) patients that had an OPTIONS-DC completed an antibiotic course and 6 (12%) left the hospital prematurely. OPTIONS-DC expanded treatment options by exposing and contextualizing SUD, psychosocial risk and protective factors; incorporating patient preferences; and allowing providers to tailor antibiotic and SUD recommendations. CONCLUSIONS: OPTIONS-DC is a feasible intervention that allows providers to integrate principles of harm reduction and offer patient-centered choices among patients needing prolonged antibiotic treatment.

Understanding viral shedding of severe acute respiratory coronavirus virus 2 (SARS-CoV-2): Review of current literature.

OBJECTIVE: Transmission of SARS-CoV-2 has significant implications for hospital infection prevention and control, discharge management, and public health. We reviewed available literature to reach an evidenced-based consensus on the expected duration of viral shedding. DESIGN: We queried 4 scholarly repositories and search engines for studies reporting SARS-CoV-2 viral shedding dynamics by PCR and/or culture available through September 8, 2020. We calculated the pooled median duration of viral RNA shedding from respiratory and fecal sources. RESULTS: The review included 77 studies on SARS-CoV-2. All studies reported PCR-based testing and 12 also included viral culture data. Among 28 studies, the overall pooled median duration of RNA shedding from respiratory sources was 18.4 days (95% CI, 15.5-21.3; I2 = 98.87%; P < .01). When stratified by disease severity, the pooled median duration of viral RNA shedding from respiratory sources was 19.8 days (95% CI, 16.2-23.5; I2 = 96.42%; P < .01) among severely ill patients and 17.2 days (95% CI, 14.0-20.5; I2 = 95.64%; P < .01) in mild-to-moderate illness. Viral RNA was detected up to 92 days after symptom onset. Viable virus was isolated by culture from -6 to 20 days relative to symptom onset. CONCLUSIONS: SARS-COV-2 RNA shedding can be prolonged, yet high heterogeneity exists. Detection of viral RNA may not correlate with infectivity since available viral culture data suggests shorter durations of shedding of viable virus. Additional data are needed to determine the duration of shedding of viable virus and the implications for risk of transmission.

The Urgent Need for Medicare Reimbursement for Home Infusion Antibiotics Amidst a Pandemic.

Medicare does not reimburse for home infusion; patients requiring outpatient parenteral antimicrobial therapy must seek treatment in high-risk settings. We recommend policy change to allow for adequate social distancing during the coronavirus disease 2019 pandemic.

Clusters of nontuberculous mycobacteria linked to water sources at three Veterans Affairs medical centers.

OBJECTIVE: To characterize nontuberculous mycobacteria (NTM) associated with case clusters at 3 medical facilities. DESIGN: Retrospective cohort study using molecular typing of patient and water isolates. SETTING: Veterans Affairs Medical Centers (VAMCs). METHODS: Isolation and identification of NTM from clinical and water samples using culture, MALDI-TOF, and gene population sequencing to determine species and genetic relatedness. Clinical data were abstracted from electronic health records. RESULTS: An identical strain of Mycobacterium conceptionense was isolated from 41 patients at VA Medical Centers (VAMCs A, B, and D), and from VAMC A's ICU ice machine. Isolates were initially identified as other NTM species within the M. fortuitum clade. Sequencing analyses revealed that they were identical M. conceptionense strains. Overall, 7 patients (17%) met the criteria for pulmonary or nonpulmonary infection with NTM, and 13 of 41 (32%) were treated with effective antimicrobials regardless of infection or colonization status. Separately, a M. mucogenicum patient strain from VAMC A matched a strain isolated from a VAMC B ICU ice machine. VAMC C, in a different state, had a 4-patient cluster with Mycobacterium porcinum. Strains were identical to those isolated from sink-water samples at this facility. CONCLUSION: NTM from hospital water systems are found in hospitalized patients, often during workup for other infections, making attribution of NTM infection problematic. Variable NTM identification methods and changing taxonomy create challenges for epidemiologic investigation and linkage to environmental sources.

Dalbavancin use in an academic medical centre and associated cost savings.

Dalbavancin is a lipoglycopeptide antibiotic with unique weekly dosing active against Gram-positive organisms. This retrospective study included 37 patients receiving a mean of 2.7 weeks of dalbavancin. Nine patients (24%) were re-admitted to the hospital within 30 days. A total of 617 hospital days were saved, estimated to result in US$1 495 336 in savings and a mean cost avoidance of US$40 414 per patient. Dalbavancin provides a valuable antibiotic option that may minimise healthcare expenditure.
