RESUMO
Background: Lack of access to timely, detailed antibiotic use data has limited ambulatory antibiotic stewardship efforts. Antibiotic utilization is tracked across ambulatory care sites and emergency departments (ED) within a large integrated health system. Methods: This is a retrospective cohort analysis from June 1, 2019 to May 31, 2020 comparing antibiotic prescribing for all patients with ICD-10 diagnosis codes for cystitis, otitis media, pharyngitis, sinusitis, and upper respiratory tract infections (URTIs) among five ambulatory care departments across northeast Ohio and southeast Florida locations: ED, Urgent Care (UC), On-Demand Telehealth (TEL), Pediatrics (PED), and Primary Care (PC). Results: A total of 261,947 encounters were included (ED:56,766, UC:92,749, TEL:8,783, PED:29,151, PC:74,498) for the treatment of cystitis (30,932), otitis media (22,094), pharyngitis (59,964), sinusitis (53,693), or URTI (95,264). The population was 63% female with a median age of 34.2 years [12.8-56.3]. A total of 17% of patients had documented penicillin allergies and 18% of patients with pharyngitis received Group A Streptococcus (GAS) testing. Antibiotics were prescribed in 44% of encounters (ED:21,746 [38%], UC:45,652 [49%], TEL:4,622 [53%], PED:10,909 [37%], PC:33,547 [45%]; P < 0.001). Guideline concordant antibiotics were prescribed in 65% of encounters (ED:14,338 [66%], UC:31,532 [69%], TEL:3,869 [84%], PED:8,212 [75%], PC:17,263 [51%]; P < 0.001). Conclusions: Observed rates of antibiotic and guideline concordant antibiotic prescribing were similar to national published rates of antibiotic prescribing in the ambulatory setting. The variability in antibiotic prescribing demonstrates opportunities for targeted outpatient stewardship efforts. Timely antibiotic tracking tools can facilitate ambulatory antimicrobial stewardship activities.
RESUMO
BACKGROUND: In September 2018, pharmacy antimicrobial stewardship (AMS) services were expanded to include weekends at this academic medical center. Activities performed by AMS pharmacists on the weekends include blood culture rapid diagnostic (RDT) review, antiretroviral therapy (ART) review, prospective audit and feedback (PAF) utilizing clinical decision support, vancomycin dosing, and operational support. The purpose of this study was to assess the operational and clinical impact of these expanded AMS services. METHODS: This single-center, quasi-experimental study included data from weekends before (9/2017-11/2017) and after (9/2018-11/2018) implementation. The descriptive primary outcome was the number of activities completed for each AMS activity type in the post-implementation group only. Secondary outcomes were time to AMS opportunity resolution, time to escalation or de-escalation following PAF or RDT alert, time to resolution of miscellaneous AMS related opportunities, length of stay (LOS), and antimicrobial use outcomes. RESULTS: During the post-implementation period 1258 activities were completed, averaging 97/weekend. Inclusion criteria for time to resolution outcomes were met by 72 patients pre-implementation and 59 patients post. The median (IQR) time to AMS opportunity resolution decreased from 18.5 hours pre-intervention (7.7-35.7) to 8.5 hours post-intervention (IQR 1.8-14.0), p < 0.01. Time to escalation was 11.6 hours compared to 1.7 hours (p = 0.1), de-escalation 16.7 hours compared to 10.8 hours (p = 0.03), and miscellaneous opportunity 40.8 hours compared to 13.2 hours (p = 0.01). No differences were observed in LOS or antimicrobial use outcomes. CONCLUSION: Presence of pharmacist-driven weekend AMS services significantly reduced time to resolution of AMS opportunities. These data support the value of weekend AMS services.

OBJECTIVE: Clostridioides difficile infection (CDI) causes significant morbidity and mortality; however, the diagnosis of CDI remains controversial. The primary aim of our study was to evaluate the association of polymerase chain reaction (PCR) cycle threshold (Ct) values with CDI disease severity, recurrence, and mortality among adult patients with CDI. DESIGN: Retrospective cohort study. SETTING: Single tertiary-care hospital. PATIENTS: Adult patients diagnosed with hospital-onset, healthcare facility-associated CDI from June 2014 to September 2015. METHODS: We performed a retrospective chart review of included patients. Univariate and multivariable logistic regression methods were used to evaluate the association between Ct values and CDI severity, 8-week recurrence, and 30-day mortality. RESULTS: Among 318 included patients, 51% were male and the mean age was 62 years; ~32% of the patients developed severe CDI and 11% developed severe-complicated CDI. The 30-day all-cause mortality rate was 11% and the 8-week recurrence rate was 9.5%. The overall mean Ct value was 32.9 (range, 23-40). Multivariable analyses showed that lower values of PCR Ct were associated with increased odds of 30-day morality (odds ratio [OR] 0.83; 95% confidence interval [CI], 0.72-0.96) but were not independently associated with CDI severity (OR, 0.99; 95% CI, 0.90-1.09) or recurrence (OR, 0.88; 95% CI, 0.77-1.00). CONCLUSIONS: Our findings suggest that PCR Ct values at the time of diagnosis may have a limited predictive value and utility in clinical decision making for inpatients with CDI. Larger, prospective studies across different patient populations are needed to confirm our findings.

RESUMO
BACKGROUND: Performing high-quality surveillance for influenza-associated hospitalization (IAH) is challenging, time-consuming, and essential. OBJECTIVES: Our objectives were to develop a fully automated surveillance system for laboratory-confirmed IAH at our multihospital health system, to evaluate the performance of the automated system during the 2018 to 2019 influenza season at eight hospitals by comparing its sensitivity and positive predictive value to that of manual surveillance, and to estimate the time and cost savings associated with reliance on the automated surveillance system. METHODS: Infection preventionists (IPs) perform manual surveillance for IAH by reviewing laboratory records and making a determination about each result. For automated surveillance, we programmed a query against our Enterprise Data Vault (EDV) for cases of IAH. The EDV query was established as a dynamic data source to feed our data visualization software, automatically updating every 24 hours.To establish a gold standard of cases of IAH against which to evaluate the performance of manual and automated surveillance systems, we generated a master list of possible IAH by querying four independent information systems. We reviewed medical records and adjudicated whether each possible case represented a true case of IAH. RESULTS: We found 844 true cases of IAH, 577 (68.4%) of which were detected by the manual system and 774 (91.7%) of which were detected by the automated system. The positive predictive values of the manual and automated systems were 89.3 and 88.3%, respectively.Relying on the automated surveillance system for IAH resulted in an average recoup of 82 minutes per day for each IP and an estimated system-wide payroll redirection of $32,880 over the four heaviest weeks of influenza activity. CONCLUSION: Surveillance for IAH can be entirely automated at multihospital health systems, saving time, and money while improving case detection.

BACKGROUND: Patients recovering from coronavirus disease 2019 (COVID-19) often continue to test positive for the causative virus by polymerase chain reaction (PCR) even after clinical recovery, thereby complicating return-to-work plans. The purpose of this study was to evaluate transmission potential of COVID-19 by examining viral load with respect to time. METHODS: Health care personnel (HCP) at Cleveland Clinic diagnosed with COVID-19, who recovered without needing hospitalization, were identified. Threshold cycles (Ct) for positive PCR tests were obtained and viral loads calculated. The association of viral load with days since symptom onset was examined in a multivariable regression model, which was reduced by stepwise backward selection to only keep variables significant at a level of .05. Viral loads by day since symptom onset were predicted using the model and transmission potential evaluated by examination of a viral load-time curve. RESULTS: Over 6 weeks, 230 HCP had 528 tests performed. Viral loads declined by orders of magnitude within a few days of symptom onset. The only variable significantly associated with viral load was time since onset of symptoms. Of the area under the curve (AUC) spanning symptom onset to 30 days, 96.9% lay within the first 7 days, and 99.7% within 10 days. Findings were very similar when validated using split-sample and 10-fold cross-validation. CONCLUSIONS: Among patients with nonsevere COVID-19, viral loads in upper respiratory specimens peak by 2 or 3 days from symptom onset and decrease rapidly thereafter. The vast majority of the viral load-time AUC lies within 10 days of symptom onset.

The addition of toxin enzyme immunoassay (EIA) to nucleic acid amplification tests, including PCR, creates challenges in the diagnosis and management of Clostridioides difficile infection (CDI). There are limited data in large cohorts, with discordant results, that is, PCR-positive/EIA-negative (PCR+/EIA-) results. We conducted a retrospective cohort study on all PCR+/EIA- adult inpatients and assessed CDI-related complications and clinical failure. We identified 240 individuals. Twenty-three (9.6%) patients experienced a CDI-related complication, including 2 cases of megacolon, 1 colectomy, and 22 intensive care unit (ICU) admissions. In multivariable logistic regression analyses, baseline severe disease by Infectious Diseases Society of America (IDSA) criteria (odds ratio [OR], 5.84; 95% confidence interval [CI], 1.88 to 18.1; P = 0.002), baseline fulminant colitis (OR, 84.7; 95% CI, 14.3 to 500; P < 0.001), fever of >38.5°C (OR, 4.61; 95% CI, 1.42 to 15.0; P = 0.011), and proton pump inhibitor (PPI) use (OR, 3.50; 95% CI, 1.19 to 10.3; P = 0.023) were associated with increased odds of CDI-related complications. For 67 PCR+/EIA- patients who did not receive complete treatment, clinical failure was observed in 10 (15%) patients. A comparison of PCR+/EIA- patients who received complete treatment to all 112 PCR+/EIA+ patients showed no differences in CDI-related complications (11% and 13% for PCR+/EIA- and PCR+/EIA+ patients, respectively), 60-day all-cause mortality (17% and 18% for PCR+/EIA- and PCR+/EIA+ patients, respectively), or recurrent CDI (7% and 9% for PCR+/EIA- and PCR+/EIA+ patients, respectively). Predictors of CDI-attributable complications among PCR+/EIA- patients include baseline severe disease by IDSA criteria, baseline fulminant colitis, and fever of >38.5°C. Identifying the subgroup of PCR+/EIA- patients who could have true disease, and therefore allowing them to be targeted for treatment, is critical.

BACKGROUND: The degree to which daily intensive care unit (ICU) cleaning practices impacts bacterial burden is controversial. The study aimed to assess the utility of using adenosine triphosphate (ATP) bioluminescence assays for monitoring effectiveness of daily cleaning in ICU environments. METHODS: We sampled 364 total samples from 57 patient rooms and 18 common areas in 3 medical ICUs over 12 weeks, before and after routine daily cleaning. Endpoints were ATP levels (relative light units, RLU) and bacterial bioburden (colony forming units, CFU). RESULTS: High-touch surfaces in ICU patient rooms and common areas were contaminated before and after cleaning. Routine cleaning significantly reduced bacterial burden in patient rooms (0.14 log10 CFU reduction, Pâ¯=â¯.008; 0.21 log10 RLU reduction, P < .001) and in ICU common areas (1.18 log10 CFU reduction, P < .001; 0.72 log10 RLU reduction, P < .001). Among sites with colony counts >20 CFUs, the proportion of sites with ATP readings >250 RLU was significantly higher than those with ATP readings ≤250 RLU (90.0% vs 10.0%, P < .05). CONCLUSION: Routine cleaning significantly reduced bacterial burden on ICU environment surfaces. Although not an alternative to culture methods, ATP assays may be a useful technique to provide rapid feedback on surface cleanliness in ICU settings.

Manual counting is considered the gold standard for device day recording by the National Health Safety Network. We describe the development of a process for an electronic count of central line days across our ten-hospital health care system. Our validation process identified discordance between the electronic count and the manual count for 71% of patient care units. Adjudication of the count differences by chart review identified the electronic count to be correct 97% of the time.

BACKGROUND: Mobile ultraviolet C (UV-C) room decontamination devices are widely used in health care facilities; however, there is limited information on the perceptions of patients, health care workers (HCWs), and environmental services staff (EVS-staff) regarding their use for environmental decontamination. METHODS: An anonymous questionnaire was administered to participants in 4 medical/surgical units of a tertiary care hospital where UV-C devices were deployed for a 6-month period. Survey questions assessed perceptions regarding the importance of environmental disinfection, effectiveness of UV-C decontamination, willingness to delay hospital admission in order to use UV-C, and safety of UV-C devices. RESULTS: Questionnaires were completed by 102 patients, 130 HCWs, and 47 EVS-staff. All of the HCWs and EVS-staff and 99% of the patients agreed that environmental disinfection is important to reduce the risk of exposure from contaminated surfaces. Ninety-eight percent of the EVS-staff, 89% of the HCWs, and 96% of the patients felt that the use of UV-C as an adjunct to routine cleaning increased confidence that rooms are clean. Ninety-four percent of the EVS-staff, 85% of the HCWs, and 90% of the patients expressed a willingness to delay being admitted to a room in order to have UV-C decontamination completed. Seventy-nine percent of the EVS-staff, 76% of the HCWs, and 86% of the patients had no concerns about the safety of UV-C devices. CONCLUSIONS: Patients, HCWs, and EVS-staff agreed that environmental disinfection is important and that UV-C devices are efficacious and safe. Educational tools are needed to allay safety concerns expressed by a minority of HCWs and EVS-staff.

We evaluated the impact of an electronic health record based 72-hour antimicrobial time-out (ATO) on antimicrobial utilization. We observed that 6 hours after the ATO, 21% of empiric antimicrobials were discontinued or de-escalated. There was a significant reduction in the duration of antimicrobial therapy but no impact on overall antimicrobial usage metrics.

OBJECTIVE: Multiple studies have demonstrated that daily chlorhexidine gluconate (CHG) bathing is associated with a significant reduction in infections caused by gram-positive pathogens. However, there are limited data on the effectiveness of daily CHG bathing on gram-negative infections. The aim of this study was to determine whether daily CHG bathing is effective in reducing the rate of gram-negative infections in adult intensive care unit (ICU) patients. DESIGN: We searched MEDLINE and 3 other databases for original studies comparing daily bathing with and without CHG. Two investigators extracted data independently on baseline characteristics, study design, form and concentration of CHG, incidence, and outcomes related to gram-negative infections. Data were combined using a random-effects model and pooled relative risk ratios (RRs), and 95% confidence intervals (CIs) were derived. RESULTS: In total, 15 studies (n = 34,895 patients) met inclusion criteria. Daily CHG bathing was not significantly associated with a lower risk of gram-negative infections compared with controls (RR, 0.89; 95% CI, 0.73-1.08; P = .24). Subgroup analysis demonstrated that daily CHG bathing was not effective for reducing the risk of gram-negative infections caused by Acinetobacter, Escherichia coli, Klebsiella, Enterobacter, or Pseudomonas spp. CONCLUSIONS: The use of daily CHG bathing was not associated with a lower risk of gram-negative infections. Further, better designed trials with adequate power and with gram-negative infections as the primary end point are needed.

OBJECTIVE: A significant portion of patients with Clostridium difficile infections (CDI) experience recurrence, and there is little consensus on its treatment. With the availability of newer agents for CDI and the added burdens of recurrent disease, a cost-effectiveness analysis may provide insight on the most efficient use of resources. DESIGN: A decision-tree analysis was created to compare the cost-effectiveness of 3 possible treatments for patients with first CDI recurrence: oral vancomycin, fidaxomicin, or bezlotoxumab plus vancomycin. The model was performed from a payer's perspective with direct cost inputs and a timeline of 1 year. A systematic review of literature was performed to identify clinical, utility, and cost data. Quality-adjusted life years (QALY) and incremental cost-effectiveness ratios were calculated. The willingness-to-pay (WTP) threshold was set at $100,000 per QALY gained. The robustness of the model was tested using one-way sensitivity analyses and probabilistic sensitivity analysis. RESULTS: Vancomycin had the lowest cost ($15,692) and was associated with a QALY gain of 0.8019 years. Bezlotoxumab plus vancomycin was a dominated strategy. Fidaxomicin led to a higher QALY compared to vancomycin, at an incremental cost of $500,975 per QALY gained. Based on our WTP threshold, vancomycin alone was the most cost-effective regimen for treating the first recurrence of CDI. Sensitivity analyses demonstrated the model's robustness. CONCLUSIONS: Vancomycin alone appears to be the most cost-effective regimen for the treatment of first recurrence of CDI. Fidaxomicin alone led to the highest QALY gained, but at a cost beyond what is considered cost-effective.

OBJECTIVE Contaminated hands of healthcare workers (HCWs) are an important source of transmission of healthcare-associated infections. Alcohol-based hand sanitizers, while effective, do not provide sustained antimicrobial activity. The objective of this study was to compare the immediate and persistent activity of 2 hand hygiene products (ethanol [61% w/v] plus chlorhexidine gluconate [CHG; 1.0% solution] and ethanol only [70% v/v]) when used in an intensive care unit (ICU). DESIGN Prospective, randomized, double-blinded, crossover study SETTING Three ICUs at a large teaching hospital PARTICIPANTS In total, 51 HCWs involved in direct patient care were enrolled in and completed the study. METHODS All HCWs were randomized 1:1 to either product. Hand prints were obtained immediately after the product was applied and again after spending 4-7 minutes in the ICU common areas prior to entering a patient room or leaving the area. The numbers of aerobic colony-forming units (CFU) were compared for the 2 groups after log transformation. Each participant tested the alternative product after a 3-day washout period. RESULTS On bare hands, use of ethanol plus CHG was associated with significantly lower recovery of aerobic CFU, both immediately after use (0.27 ± 0.05 and 0.88 ± 0.08 log10 CFU; P = .035) and after spending time in ICU common areas (1.81 ± 0.07 and 2.17 ± 0.05 log10 CFU; P<.0001). Both the antiseptics were well tolerated by HCWs. CONCLUSIONS In comparison to the ethanol-only product, the ethanol plus CHG sanitizer was associated with significantly lower aerobic bacterial counts on hands of HCWs, both immediately after use and after spending time in ICU common areas.

BACKGROUND: Clinical practice guidelines provide recommendations for surgical prophylaxis in patients undergoing cardiothoracic procedures. However, currently no recommendations guide the management of antibiotic prophylaxis in patients who require delayed sternal closure after cardiothoracic operation. METHODS: This is a single-center, retrospective analysis. Data were extracted from The Society of Thoracic Surgery database and electronic medical record from July 2011 through January 2016. Patients included are adults (≥18 years old) after cardiothoracic operation with delayed sternal closure. RESULTS: A total of 167 patients were included for analysis. The majority of patients (131, 78.4%) were continued on routine antibiotics and 36 patients (21.6%) were switched to broad-spectrum antibiotics for prophylaxis. Of patients on routine antibiotic prophylaxis, 6 (4.6%) experienced a sternal surgical site infection, whereas 3 patients (8.3%) switched to broad-spectrum agents before chest closure experienced a sternal surgical site infection (p = 0.407). Eleven patients (6.6%) received an abbreviated duration of antibiotics, 52 patients (31.1%) were continued on antibiotics until the time of sternal closure, and 104 patients (62.3%) were continued on antibiotics past the time of sternal closure. The incidence of infection based on duration of prophylactic antibiotic was 0, 1 (1.9%), and 8 (7.7%), respectively (p = 0.352). CONCLUSIONS: Substantial variation was found in the duration and selection of antibiotic prophylaxis for patients with delayed sternal closure after cardiothoracic operation. Broad-spectrum antimicrobial agents and extended durations of antibiotic prophylaxis were not associated with benefits in the incidence of sternal wound infection and may increase the risk of adverse effects.

OBJECTIVES: To determine the value of surgery for infective endocarditis (IE) in patients on hemodialysis by comparing the nature and invasiveness of endocarditis in hemodialysis and nonhemodialysis patients and their hospital and long-term outcomes, and identifying risk factors for time-related mortality after surgery. METHODS: From January 1997 to January 2013, 144 patients on chronic hemodialysis and 1233 nonhemodialysis patients underwent valve surgery for IE at our institution. Propensity matching identified 99 well-matched hemodialysis and nonhemodialysis patient pairs for comparison of outcomes. RESULTS: Staphylococcus aureus infection was more common in hemodialysis patients than in nonhemodialysis patients (42% vs 21%; P < .0001), but invasive disease was similar in the 2 groups (47%; P = .3). Hospital mortality was 13% and 5-year survival was 20% for hemodialysis patients, 20% below that expected in a general hemodialysis population but 15% above that of hemodialysis patients treated nonsurgically for IE. For matched patients, hospital mortality was 13% for hemodialysis patients versus 5.1% for nonhemodialysis patients (P = .05), and survival at 1 and 5 years was 56% versus 83% and 24% versus 59%, respectively (P < .004). Use of an arteriovenous graft for dialysis access (P = .01) and preoperative placement of a pacemaker (P < .0001) were risk factors for late mortality in hemodialysis patients. For matched patients, freedom from reoperation was similar in the hemodialysis and nonhemodialysis groups (P > .9). CONCLUSIONS: Intermediate-term survival after surgery for IE in hemodialysis patients is substantially worse than that in nonhemodialysis patients, but only slightly worse than that in the general hemodialysis population and substantially better than that in hemodialysis patients with IE treated nonsurgically, supporting continued surgical intervention for IE.

BACKGROUND Catheter-associated urinary tract infections (CAUTIs) are among the most common hospital-acquired infections (HAIs). Reducing CAUTI rates has become a major focus of attention due to increasing public health concerns and reimbursement implications. OBJECTIVE To implement and describe a multifaceted intervention to decrease CAUTIs in our ICUs with an emphasis on indications for obtaining a urine culture. METHODS A project team composed of all critical care disciplines was assembled to address an institutional goal of decreasing CAUTIs. Interventions implemented between year 1 and year 2 included protocols recommended by the Centers for Disease Control and Prevention for placement, maintenance, and removal of catheters. Leaders from all critical care disciplines agreed to align routine culturing practice with American College of Critical Care Medicine (ACCCM) and Infectious Disease Society of America (IDSA) guidelines for evaluating a fever in a critically ill patient. Surveillance data for CAUTI and hospital-acquired bloodstream infection (HABSI) were recorded prospectively according to National Healthcare Safety Network (NHSN) protocols. Device utilization ratios (DURs), rates of CAUTI, HABSI, and urine cultures were calculated and compared. RESULTS The CAUTI rate decreased from 3.0 per 1,000 catheter days in 2013 to 1.9 in 2014. The DUR was 0.7 in 2013 and 0.68 in 2014. The HABSI rates per 1,000 patient days decreased from 2.8 in 2013 to 2.4 in 2014. CONCLUSIONS Effectively reducing ICU CAUTI rates requires a multifaceted and collaborative approach; stewardship of culturing was a key and safe component of our successful reduction efforts.
