Reportable infections following colon surgery in a large public healthcare system in New York City: The consequences of being a level 1 trauma center.

OBJECTIVES: To examine differences in risk factors and outcomes of patients undergoing colon surgery in level 1 trauma centers versus other hospitals and to investigate the potential financial impact of these reportable infections. DESIGN: Retrospective cohort study between 2015 and 2022. SETTING: Large public healthcare system in New York City. PARTICIPANTS: All patients undergoing colon surgery; comparisons were made between (1) all patients undergoing colon surgery at the level 1 trauma centers versus patients at the other hospitals and (2) the nontrauma and trauma patients at the level 1 trauma centers versus the nontrauma patients at other hospitals. RESULTS: Of 5,217 colon surgeries reported, 3,531 were at level 1 trauma centers and 1686 at other hospitals. Patients at level 1 trauma centers had significantly increased American Society of Anesthesiology (ASA) scores, durations of surgery, rates of delayed wound closure, and rates of class 4 wounds, resulting in higher SIRs (1.1 ± 0.15 vs 0.75 ± 0.18; P = .0007) compared to the other hospitals. Compared to the nontrauma patients at the other hospitals, both the nontrauma and trauma patients at the level 1 trauma centers had higher ASA scores, rates of delayed wound closure, and of class 4 wounds. The SIRs of the nontrauma patients (1.16 ± 1.29; P = .008) and trauma patients (1.26 ± 2.69; P = .066) at the level 1 trauma center were higher than the SIRs of nontrauma patients in the other hospitals (0.65 ± 1.18). CONCLUSIONS: Patients undergoing colon surgery at level 1 trauma centers had increased complexity of surgery compared to the patients in other hospitals. Until there is appropriate adjustment for these risk factors, the use of infections following colon surgery as a reportable quality measure should be re-evaluated.

Impact of Prophylactic Antibiotic Selection on the Prevention and Bacterial Flora of Surgical Site Infections After Colorectal Surgery.

Background: Deep incisional and organ/space surgical site infections (SSIs) after colorectal surgery are associated with adverse outcomes. Multiple antibiotic regimens are recommended for peri-operative prophylaxis, with no particular regimen preferred over another. We compared the prophylaxis regimens used in patients with and without SSIs, and the impact of regimens on the flora involved in SSIs. Patients and Methods: Information was extracted from the National Healthcare Safety Network databank of patients undergoing colorectal surgery from 2015 to 2022 in a large public healthcare system in New York City. Patients with SSIs were identified, and controlling for nine variables, propensity score matching was used to create a matched control group without SSIs. Prophylactic regimens were compared between the matched groups with and without SSIs. Also, for the patients with SSIs, the impact of the prophylactic regimen on the subsequent pathogens involved the infection was examined. Results: A total of 275 patients with SSIs were compared to a matched cohort without SSIs. The prophylactic regimens were extremely similar between the SSI and control groups. Among the patients who developed SSIs, more patients who received cefoxitin had emergence of select cephalosporin-resistant Enterobacterales and Bacteroides spp. when compared with those who received ß-lactam-ß-lactamase inhibitors. Conclusions: The distribution of surgical prophylaxis regimens was remarkably similar between patients developing serious SSIs and a closely matched cohort that did not develop an SSI. However, given the downstream effects of more resistant and anaerobic flora should an infection develop, use of cefoxitin should be re-evaluated as a prophylactic agent.

Carbapenem-Resistant Klebsiella pneumoniae in Large Public Acute-Care Healthcare System, New York, New York, USA, 2016-2022.

Controlling the spread of carbapenem-resistant Enterobacterales is a global priority. Using National Healthcare Safety Network data, we characterized the changing epidemiology of carbapenem-resistant Klebsiella pneumoniae (CRKP) in a large public health system in New York, New York, USA. During 2016-2020, CRKP cases declined; however, during 2021-June 2022, a notable increase occurred. Of 509 cases, 262 (51%) were considered community-onset, including 149 in patients who were living at home. Of 182 isolates with proven or presumptive (ceftazidime/avibactam susceptible) enzymes, 143 were serine carbapenemases; most confirmed cases were K. pneumoniae carbapenemase. The remaining 39 cases were proven or presumptive metallo-ß-lactamases; all confirmed cases were New Delhi metallo-ß-lactamases. After 2020, a marked increase occurred in the percentage of isolates possessing metallo-ß-lactamases. Most patients with metallo-ß-lactamases originated from long-term care facilities. An aggressive and universal program involving surveillance and isolation will be needed to control the spread of CRKP in the city of New York.

Comparison of Tocilizumab vs Baricitinib in Clinical Outcomes Among Hospitalized Patients With COVID-19: Experience From a Public Hospital System in New York City.

Background: Tocilizumab and baricitinib are immunomodulators that have been repurposed for the treatment of coronavirus disease 2019 (COVID-19). Whether one medication should be preferred over the other has not been established. Methods: This multicenter retrospective cohort study comprised hospitalized patients with COVID-19 who received either tocilizumab or baricitinib. The primary outcome was improvement in respiratory status (at least 1-point reduction on the respiratory ordinal scale) at day 7 and up to day 28. Secondary outcomes included mortality, disposition, deep vein thrombosis, pulmonary embolism, or positive blood culture. Outcomes were stratified by baseline respiratory status and variant-predominating periods. Results were reported for the overall and propensity-matched cohorts. Results: A total of 921 patients received tocilizumab and 638 received baricitinib. The propensity-matched cohort included 597 patients in each group. At day 7 in the overall and propensity-matched cohorts, significantly more patients had improvement in respiratory status in the baricitinib group. These improvements were seen in patients requiring supplemental oxygen and noninvasive ventilation/high-flow oxygen but not in patients requiring mechanical ventilation. Favorable outcomes with baricitinib were observed during the Alpha and Omicron periods. By day 28, there were no differences in the changes of respiratory status for the treatment groups in either cohort. Also, no differences were seen in mortality, disposition, development of deep vein thrombosis/pulmonary embolism, or bloodstream infections. Conclusions: Baricitinib treatment was associated with more favorable respiratory improvement at day 7 when compared with tocilizumab, but no differences were observed up to day 28.

Is remdesivir safe in patients with renal impairment? Experience at a large tertiary urban medical center.

PURPOSE: Remdesivir is FDA-approved for treatment of patients hospitalized with COVID-19 pneumonia, but not recommended in patients with severe renal failure. This study aims to evaluate the safety of remdesivir in this patient population. METHODS: This was a single-center, retrospective cohort study including patients ≥ 18 years old, admitted between May 1, 2020 and April 30, 2021 who received remdesivir. Patients were divided into two groups: estimated creatinine clearance (eCrCl) < 30 mL/min and eCrCl ≥ 30 ml/min. Primary outcomes were development of acute kidney injury (AKI) after remdesivir initiation and hepatotoxicity (alanine aminotransferase [ALT] or aspartate aminotransferase [AST] > 5 × upper limit of normal) both at end of treatment (EOT) or 5 days after EOT. Secondary outcomes were length of stay (days) and mortality. RESULTS: 513 patients were assessed with 416 patients included in the study (eCrCl < 30 mL/min, n = 55; eCrCl ≥ 30 mL/min n = 361). Incidence of AKI (eCrCl < 30 mL/min 11% vs eCrCl ≥ 30 mL/min 7%, OR 1.57, 95% CI 0.57, 4.3) and hepatotoxicity (ALT: 2% vs 4%, OR 0.47, 95% CI 0.05, 3.7 and AST: 2% vs 2%, OR 1.26, 95% CI 0.14, 11.04) were similar between the two groups. Length of stay was longer in the eCrCl < 30 mL/min group (mean 18.6 vs 11.9, difference 6.7, 95% CI 3.8, 9.6), and no difference in mortality was observed (21.8% vs 18.8%, OR 1.2, 95% CI 0.6, 2.4). CONCLUSION: Remdesivir was not associated with development of AKI or hepatotoxicity in patients with eCrCl < 30 mL/min compared to patients with eCrCl ≥ 30 mL/min, and warrants further investigation.

Methicillin-resistant Staphylococcus aureus bacteremia during the coronavirus disease 2019 (COVID-19) pandemic: Trends and distinguishing characteristics among patients in a healthcare system in New York City.

During the pandemic, the rate of healthcare facility-onset methicillin-resistant Staphylococcus aureus (MRSA) bacteremia was 5 times greater in patients admitted with coronavirus disease 2019 (COVID-19). The presence of central lines and mechanical ventilation likely contribute to this increased rate. The number of central-line-associated bacteremia cases may be underestimated in patients with COVID-19.

Trends in Clostridioides difficile infection across a public health hospital system in New York City 2019-2021: A cautionary note.

Contrary to national reports, rates of healthcare facility-onset Clostridioides difficile infection across an 11-hospital system rose after the spring of 2020, when New York City was the epicenter for the COVID-19 pandemic. Antibiotic pressure from an escalation in cephalosporin usage correlated with this increase. The majority of cases of Clostridioides difficile were in patients without COVID-19, suggesting the pandemic has adversely impacted the healthcare of other inpatients.

Trends in Healthcare Facility-Onset Clostridioides difficile Infection and the Impact of Testing Schemes in an Acute Care Hospital System in New York City, 2016-2019.

BACKGROUND: Healthcare facility-onset Clostridioides difficile infection is associated with adverse clinical outcomes and hospital reimbursement. A four-year review involving eleven hospitals of the NYC Health + Hospital system was undertaken. METHODS: From 2016-2019, infection rates and standardized infection ratios (SIRs) were gathered from National Healthcare Safety Network. The C. difficile testing scheme at each facility was recorded. RESULTS: For the eleven hospitals, declines in rates of C. difficile infection and SIRs were documented. However, this decline was driven by two hospitals that had high rates of infection in 2016; for the remaining nine hospitals, rates of infection and SIRs were at a plateau. Most hospitals used a testing scheme that fell into the nucleic acid amplification test (NAAT) category for SIR risk adjustment. Hospitals that used the algorithm glutamate dehydrogenase (GDH) and toxin A/B immunoassay (EIA) followed by NAAT for discrepant results had significantly lower rates of C. difficile infection but similar SIRs. CONCLUSIONS: For most hospitals in this system, rates of C. difficile remained level. Within the NAAT test categories, SIRs may not correlate with infection rates. Given the controversies regarding testing and calculation of SIRs, alternatives to C. difficile infection should be sought as a hospital quality measurement.

Effectiveness of Fluconazole Prophylaxis in a Targeted High-Risk Group in a Surgical Intensive Care Unit.

Background: Candidemia is an important nosocomial infection in intensive care units (ICUs), with total parenteral nutrition (TPN) a well-recognized risk factor. Antifungal prophylaxis may be an effective intervention to prevent candidemia in high-risk patients. In this report, the effectiveness of fluconazole prophylaxis was examined in patients located in a combined surgical-neurosurgical ICU serving an urban Level 1 trauma center who were receiving prolonged courses of TPN. Methods: Fluconazole was administered prophylactically for patients receiving TPN for more than six days. Rates of candidemia during the intervention were compared with those prior to the intervention. Results: During the 27-month pre-intervention period, seven episodes of candidemia occurred during 1,277 days of parenteral nutrition therapy. During the 17-month post-intervention period, there were zero episodes during 852 days of therapy (p = 0.03). Similarly, during the pre-intervention period, there were six episodes of candidemia during 867 high-risk days of therapy, compared with zero during 643 days of high-risk therapy in the post-intervention period (p = 0.04). The rates of bacteremia did not change, and emergence of fluconazole-resistant Candida species was not evident. Conclusions: At our surgical ICU, this fluconazole prophylaxis was associated with a significant decrease in the number of patients with candidemia, without emergence of resistant species.

Tocilizumab therapy for COVID-19: A comparison of subcutaneous and intravenous therapies.

BACKGROUND: The release of pro-inflammatory cytokines, resulting in cytokine storm syndrome, contributes to the morbidity and mortality associated with COVID-19 disease. This study aimed to compare the effects of intravenous (IV) and subcutaneous (SC) tocilizumab, an IL-6 receptor antagonist, on respiratory parameters and clinical outcome in patients with COVID 19. METHODS: We performed a retrospective cohort study of hospitalized patients with COVID-19 treated with either IV or SC tocilizumab from March 26, 2020, to May 18, 2020. Respiratory parameters seven days after receiving tocilizumab therapy were compared to baseline measurements. All patients were assessed until discharged from the hospital. RESULTS: Tocilizumab was administered to 125 patients: 65 received IV, and 60 received SC therapy. At day seven, 52% of the IV group patients demonstrated improvement in respiratory parameters, compared to 28% in the SC group (P = 0.01). Mortality rates at days seven and 28 were 15% and 37%, respectively, in the IV group and 17% and 50%, respectively, in the SC group (PNS). The in-hospital mortality rate was 38% for the IV group versus 57% for the SC group (P = 0.04). More than 90% of patients in each group received corticosteroids; however, significantly more patients received convalescent plasma in the IV group. CONCLUSIONS: At the doses used in this study, IV tocilizumab is preferred over SC therapy to treat cytokine storm syndrome due to COVID-19.

Complementary and alternative medicine education in U.S. schools and colleges of pharmacy.

INTRODUCTION: The objective of this survey is to provide an update on the state of complementary and alternative medicine (CAM) education and describe instructional and assessment methods across schools and colleges of pharmacy. METHODS: One hundred thirty-five schools of pharmacy were contacted to participate in a survey describing the incorporation of CAM education into their respective curricula. The survey also inquired about perceived barriers and future plans for CAM-related courses. RESULTS: Ninety-six schools responded to the survey (71.1%), with all schools reporting that CAM is incorporated into the curriculum. Topics covered, teaching strategies, and assessment methods varied among the 74 elective and 116 required courses described. Respondents listed lack of evidence to support CAM use as the most common barrier to CAM education, and 50% of respondents reported plans for expansion of CAM education at their schools. CONCLUSIONS: CAM education in pharmacy curricula has grown over the last decade, but remains varied in topics taught and teaching methods.
