Impact of Accelerate Pheno and BacT/Alert Virtuo on Clinical Processes and Outcomes in Patients with Sepsis and Concurrent Gram-Negative Bacteremia.

The Accelerate Pheno and BacT/Alert Virtuo systems may improve bacteremia management. Here, we evaluated the impact of both devices on outcomes in patients with sepsis and concurrent Gram-negative bacteremia. This quasiexperimental study included a retrospective preimplementation and a prospective postimplementation group. Patients ≥18 years old with Gram-negative bacteremia were included. Patients with neutropenia, pregnant patients, those who were transferred from an outside hospital with active bloodstream infections, and those with polymicrobial bacteremia were excluded. Blood culture incubation in the BacT/Alert 3D device and microdilution antimicrobial susceptibility testing from culture plate growth were used prior to implementation of the BacT/Alert Virtuo and Accelerate Pheno systems. Matrix-assisted laser desorption ionization-time of flight (MALDI-TOF) identification directly from blood culture was used pre- and postimplementation. Time to Gram stain results, identification, susceptibility reporting, initiation of narrow-spectrum Gram-negative therapy at 72 h, 30-day inpatient mortality, sepsis resolution, and length of hospital stay were evaluated. A total of 116 patients were included (63 preimplementation, 53 postimplementation). Median times to Gram stain and susceptibility results were significantly shorter postimplementation (P < 0.001). The postimplementation group had an improved hazard ratio for narrow-spectrum Gram-negative therapy at 72 h (hazard ratio [HR], 2.685 [95% confidence interval {CI}, 1.348 to 5.349]), a reduced hazard ratio for 30-day inpatient mortality (adjusted HR [aHR], 0.150 [95% CI, 0.026 to 0.846]), and improved sepsis resolution (92.5% versus 77.8% [P = 0.030]). The length of hospital stay was unchanged after implementation. We conclude that implementation of the BacT/Alert Virtuo and Accelerate Pheno systems improved microbiology laboratory processes, antibiotic utilization processes, and clinical outcomes. These data support the use of rapid diagnostics in sepsis with concurrent Gram-negative bacteremia.

On alert for Ebola: public health risk assessment of travellers from Uganda to the USA during the 2022 outbreak.

BACKGROUND: On 20 September 2022, the Ugandan Ministry of Health declared an outbreak of Ebola disease caused by Sudan ebolavirus. METHODS: From 6 October 2022 to 10 January 2023, Centers for Disease Control and Prevention (CDC) staff conducted public health assessments at five US ports of entry for travellers identified as having been in Uganda in the past 21 days. CDC also recommended that state, local and territorial health departments ('health departments') conduct post-arrival monitoring of these travellers. CDC provided traveller contact information, daily to 58 health departments, and collected health department data regarding monitoring outcomes. RESULTS: Among 11 583 travellers screened, 132 (1%) required additional assessment due to potential exposures or symptoms of concern. Fifty-three (91%) health departments reported receiving traveller data from CDC for 10 114 (87%) travellers, of whom 8499 (84%) were contacted for monitoring, 1547 (15%) could not be contacted and 68 (1%) had no reported outcomes. No travellers with high-risk exposures or Ebola disease were identified. CONCLUSION: Entry risk assessment and post-arrival monitoring of travellers are resource-intensive activities that had low demonstrated yield during this and previous outbreaks. The efficiency of future responses could be improved by incorporating an assessment of risk of importation of disease, accounting for individual travellers' potential for exposure, and expanded use of methods that reduce burden to federal agencies, health departments, and travellers.

Demographic and travel characteristics and self-reported predeparture SARS-CoV-2 testing behavior in air passengers entering the United States from foreign destinations from July to September 2021.

INTRODUCTION: From January 2021 to June 2022, the United States Centers for Disease Control and Prevention required predeparture SARS-CoV-2 testing for all air passengers arriving into the United States from a foreign country. METHODS: Using data collected during a surveillance project, we described predeparture testing behavior among a convenience sample of international air passengers entering the United States from July to September 2021 at six US ports of entry. We analyzed pairwise relationships between self-reported test type, test timing, demographic and travel characteristics, and COVID-19 vaccination status using chi-square and Fisher's exact tests. RESULTS: Participants were more likely to get a NAAT versus antigen test if they identified as non-Hispanic Asian or Pacific Islander (68.2%, n = 173), non-Hispanic Black (62.6%, n = 147), or if they preferred not to report race and ethnicity (60.8%, n = 209) when compared to those who identified as non-Hispanic White (47.1%, n = 1086, all p < 0.05). Those who identified as Hispanic or Latino (n = 671) were less likely to get a NAAT than the non-Hispanic White group (39.5% vs. 47.1%, p < 0.05). Participants arriving in the US from the Americas were less likely to get a NAAT (38.5%, n = 871) compared to those arriving from Europe (45.5%, n = 1165, p < 0.05). Participants who reported receiving their predeparture test 2 days or 3 or more days before departure were more likely to report receiving a NAAT (52.2%, n = 879, and 60.2%, n = 410, respectively) than those who reported testing within 1 day (41.4%, n = 1040, all p < 0.001) of departure. DISCUSSION: Test type was significantly associated with race and ethnicity, departure region, and test timing. Differences likely reflected regional disparities in the availability of tests at the time of the activity. Discrepancies in predeparture test timing and type worldwide may have consequences for the effectiveness and equity of travel requirements in future pandemics.

Effect of oral vancomycin dose on outcomes in patients with Clostridioides difficile infection.

Clostridioides difficile infection (CDI) is a significant cause of morbidity and mortality. Oral vancomycin is a cornerstone of CDI treatment, but dosing strategies in clinical practice may differ from guideline recommendations. This study aimed to determine differences in outcomes between patients treated with standard (125 mg QID) and high-dose (≥250 mg QID) oral vancomycin. This dual-centre study evaluated adult patients admitted between January 2013 and July 2017. Patients were included in the study if they had a positive C. difficile toxin PCR, symptomatic infection and received ≥48 h of oral vancomycin. Disease severity was characterised using a variety of classifiers, including guideline definitions. The primary outcome was 90-day CDI recurrence; secondary outcomes included clinical failure, in-hospital mortality and 90-day re-admission. Inverse probability of treatment weighting (IPTW) was conducted to balance differences between groups. A total of 535 patients were included; 261 received standard and 274 received high-dose vancomycin. Baseline demographics were similar between groups, except that patients receiving high-dose vancomycin were more likely to have more severe disease and to be admitted to the ICU. Few patients had fulminant disease (14.4%). No significant differences in recurrence (OR, 1.52, 95% CI 0.82-2.84), clinical failure (OR, 0.64, 95% CI 0.328-1.26), mortality (OR, 1.44, 95% CI 0.78-2.66) or re-admission (OR, 1.03, 95% CI 0.70-1.51) were identified between patients receiving standard and high-dose vancomycin in the IPTW analyses. No differences in recurrence, mortality or re-admission were identified between standard and high-dose vancomycin for the treatment of CDI not requiring surgery.

Time to clinical response in sepsis associated with an algorithm for blood-culture pathogen identification using matrix-assisted laser desorption ionization time-of-flight mass spectroscopy.

PURPOSE: Antimicrobial stewardship programs (ASPs) can be aided by using rapid diagnostics (RDT). However, there are limited data evaluating the impact of ASPs and RDT on sepsis outcomes in the setting of the new Sepsis-3 guidelines. This study evaluates the impact of a low-resource method for ASPs with RDT on sepsis outcomes. METHODS: This was a prospective, quasi-experimental study with a retrospective double pretest. Patients ≥ 18 years old with sepsis and concurrent bacteremia or fungemia were included; patients who were pregnant, had polymicrobial septicemia or who were transferred from an outside hospital were excluded. In the first pretest (O1), polymerase chain reaction was used to identify Staphylococcal species from positive blood cultures, and traditional laboratory techniques were used to identify other species. Matrix-assisted laser desorption ionization time-of-flight mass spectroscopy and FilmArray were implemented in the second pretest (O2), and twice daily blood culture review was implemented in the posttest (O3). RESULTS: A total of 394 patients (157 in O1, 176 in O2, 61 in O3) were enrolled. Clinical response was 73.2%, 83.5%, and 88.5% in O1, O2, and O3, respectively, p = 0.013. By Cox regression, the O3 was associated with improved time to clinical response (hazard ratio, 1.388; 95% confidence interval, 1.004-1.919) as compared with O1. Mortality, hospital length of stay, and intensive care unit length of stay were unchanged between groups. CONCLUSION: Twice-daily blood culture review may be useful for implementing rapid diagnostics within low-resource ASPs. Further research is needed to identify the optimal method of blood culture follow-up within low-resource settings.

Billing for inpatient hospital care.

Pharmacy personnel billing patients for services rendered is discussed. Billing for services is a critical function for maintaining the financial viability of health care institutions. Poor understanding of the system can lead to incorrect documentation, which can result in a claim rejection. The UB-92 provides hospitals with the proper format to request reimbursement for services provided. To ensure proper reimbursement, appropriate coding of International Classification of Diseases, 9th Revision, Clinical Modification (ICD-9-CM) codes for diagnosis, procedures, and services provided is necessary. Ancillary services, such as pharmacy, play a crucial role in the completion of the bill by ensuring that the charge-master accurately represents the service provided. This information includes identification, charge, cost, and revenue codes. Hospital billing agents must also account for any outpatient visits that may have occurred within three days of admission, since these charges may need to be included on the hospital bill. In order for the billing process to be effective, it is important that all personnel have a thorough understanding of the billing process and be able to effectively communicate with each other.
