Stopping Hospital Infections With Environmental Services (SHINE): A Cluster-randomized Trial of Intensive Monitoring Methods for Terminal Room Cleaning on Rates of Multidrug-resistant Organisms in the Intensive Care Unit.

BACKGROUND: Multidrug-resistant organisms (MDROs) frequently contaminate hospital environments. We performed a multicenter, cluster-randomized, crossover trial of 2 methods for monitoring of terminal cleaning effectiveness. METHODS: Six intensive care units (ICUs) at 3 medical centers received both interventions sequentially, in randomized order. Ten surfaces were surveyed each in 5 rooms weekly, after terminal cleaning, with adenosine triphosphate (ATP) monitoring or an ultraviolet fluorescent marker (UV/F). Results were delivered to environmental services staff in real time with failing surfaces recleaned. We measured monthly rates of MDRO infection or colonization, including methicillin-resistant Staphylococcus aureus, Clostridioides difficile, vancomycin-resistant Enterococcus, and MDR gram-negative bacilli (MDR-GNB) during a 12-month baseline period and sequential 6-month intervention periods, separated by a 2-month washout. Primary analysis compared only the randomized intervention periods, whereas secondary analysis included the baseline. RESULTS: The ATP method was associated with a reduction in incidence rate of MDRO infection or colonization compared with the UV/F period (incidence rate ratio [IRR] 0.876; 95% confidence interval [CI], 0.807-0.951; P = .002). Including the baseline period, the ATP method was associated with reduced infection with MDROs (IRR 0.924; 95% CI, 0.855-0.998; P = .04), and MDR-GNB infection or colonization (IRR 0.856; 95% CI, 0.825-0.887; P < .001). The UV/F intervention was not associated with a statistically significant impact on these outcomes. Room turnaround time increased by a median of 1 minute with the ATP intervention and 4.5 minutes with UV/F compared with baseline. CONCLUSIONS: Intensive monitoring of ICU terminal room cleaning with an ATP modality is associated with a reduction of MDRO infection and colonization.

Fluoroquinolone Prophylaxis Is Highly Effective for the Prevention of Central Line-Associated Bloodstream Infections in Autologous Stem Cell Transplant Patients.

Patients undergoing stem cell transplant (SCT) for the treatment of hematologic malignancy are at increased risk for central line-associated bloodstream infections (CLABSIs). The use of prophylactic antibiotics to prevent CLABSIs in the setting of autologous SCT is of unclear benefit. We aimed to evaluate the impact of levofloxacin prophylaxis on reducing CLABSIs in this high-risk population. Patients undergoing autologous SCT at a tertiary care hospital received levofloxacin prophylaxis from January 13, 2016 to January 12, 2017. Levofloxacin was administered from autologous SCT (day 0) until day 13, absolute neutrophil count > 500/mm3, or neutropenic fever, whichever occurred first. Clinical outcomes were compared with a baseline group who underwent autologous SCT but did not receive antibacterial prophylaxis during the previous year. The primary endpoint was incidence of CLABSIs assessed using Cox proportional hazards regression. A total of 324 patients underwent autologous SCT during the entire study period, with 150 receiving levofloxacin prophylaxis during the intervention period. The rate of CLABSIs was reduced from 18.4% during the baseline period to 6.0% during the intervention period. On multivariable analysis levofloxacin prophylaxis significantly reduced CLABSI incidence (hazard ratio, .33; 95% confidence interval [CI], .16 to .69; P = .003). There was also a reduction in the risk of neutropenic fever (odds ratio [OR], .23; 95% CI, .14 to .39; P < .001) and a trend toward a reduction in intensive care unit transfer for sepsis (OR, .33; 95% CI, .09 to 1.24; P = .10) in patients receiving levofloxacin prophylaxis. Notably, there was no increase in Clostridium difficile infection in the levofloxacin group (OR, .66; 95% CI, .29 to 1.49; P = .32). Levofloxacin prophylaxis was effective in reducing CLABSIs and neutropenic fever in patients undergoing autologous SCT. Further studies are needed to identify specific patient groups who will benefit most from antibiotic prophylaxis.

Novel method to assess arterial insufficiency in rodent hind limb.

BACKGROUND: Lack of techniques to assess maximal blood flow capacity thwarts the use of rodent models of arterial insufficiency to evaluate therapies for intermittent claudication. We evaluated femoral vein outflow (VO) in combination with stimulated muscle contraction as a potential method to assess functional hind limb arterial reserve and therapeutic efficacy in a rodent model of subcritical limb ischemia. MATERIALS AND METHODS: VO was measured with perivascular flow probes at rest and during stimulated calf muscle contraction in young, healthy rats (Wistar Kyoto, WKY; lean Zucker rats, LZR) and rats with cardiovascular risk factors (spontaneously hypertensive [SHR]; obese Zucker rats [OZR]) with acute and/or chronic femoral arterial occlusion. Therapeutic efficacy was assessed by administration of Ramipril or Losartan to SHR after femoral artery excision. RESULTS: VO measurement in WKY demonstrated the utility of this method to assess hind limb perfusion at rest and during calf muscle contraction. Although application to diseased models (OZR and SHR) demonstrated normal resting perfusion compared with contralateral limbs, a significant reduction in reserve capacity was uncovered with muscle stimulation. Administration of Ramipril and Losartan demonstrated significant improvement in functional arterial reserve. CONCLUSIONS: The results demonstrate that this novel method to assess distal limb perfusion in small rodents with subcritical limb ischemia is sufficient to unmask perfusion deficits not apparent at rest, detect impaired compensation in diseased animal models with risk factors, and assess therapeutic efficacy. The approach provides a significant advance in methods to investigate potential mechanisms and novel therapies for subcritical limb ischemia in preclinical rodent models.

A medial to lateral approach offers a superior lymph node harvest for laparoscopic right colectomy.

PURPOSE: Studies have shown improved survival with increasing amounts of harvested lymph nodes. The purpose of this study was to evaluate two laparoscopic techniques to right colectomy, laparoscopic medial to lateral (MtL) approach and laparoscopic lateral to medial (LtM) approach, in patients undergoing a right colectomy for either endoscopically unresectable polyps or carcinoma and determine which technique offers the optimal lymph node harvest. METHODS: Patients that underwent a laparoscopic right colectomy over a 5-year period were identified. Charts were reviewed with regards to demographics, surgical approach, length of stay (LOS) and number of lymph nodes harvested. Variables were statistically analyzed and outcomes compared between the two groups. A p value of less than 0.05 was considered statistically significant. RESULTS: Two hundred thirty-three patients underwent a laparoscopic right colectomy over a 5-year period for endoscopically unresectable polyps or carcinoma. Seventy-nine patients underwent a MtL approach and 154 patients underwent a LtM approach. When comparing the two groups, there were more females in the MtL group relative to the LtM group (78% vs 66%; p = 0.0015). When the outcome of number of lymph nodes harvested was examined, there was a significantly larger number of nodes harvested in the MtL (median = 24) approach compared to the LtM approach (median = 19; p = 0.0002). LOS was similar between the MtL and LtM group (median 4 days for both). CONCLUSIONS: The laparoscopic MtL approach to right colectomy yields a larger lymph node harvest compared to the laparoscopic LtM approach.

Attributable mortality of central line associated bloodstream infection: systematic review and meta-analysis.

PURPOSE: To identify the attributable mortality of central line associated blood stream infections (CLABSI) through meta-analysis. METHODS: Meta-analysis of case control and cohort studies, matched and unmatched, that reported on mortality of patients with and without CLABSI was performed. MEDLINE, CENTRAL, CINAHL were searched. Non-interventional studies of all languages that reported mortality in patients with CLABSI were included. Data were extracted on patient population, study setting, design, diagnostic criteria for CLABSI, and mortality. Results from studies comparing mortality due to CLABSI were pooled using a random effects model with assessment of heterogeneity. Heterogeneity of studies was assessed with an I (2) statistic and a funnel plot was generated to assess for publication bias. RESULTS: Eighteen studies were included with 1,976 CLABSI cases. Of the included studies, 17 took place in intensive care unit settings, most involved a mixed population of medical and surgical patients, and ten were matched using an illness severity index. Our findings show an odds ratio of in hospital death associated with CLABSI as 2.75 (CI 1.86-4.07) and 1.51 (CI 1.08-2.09) in the subgroup of the ten matched studies. Those studies where greater than 30 % of CLABSI were attributed to coagulase-negative Staphylococcus had an odds ratio of death of 1.64 (95 % CI 1.02-2.65) compared with 4.71 (95 % CI 1.54-14.39). CONCLUSIONS: CLABSI is associated with a significantly increased risk of death supporting the use of extensive efforts to reduce these infections.

Food Insecurity in the Elective Enhanced Recovery After Surgery Colorectal Surgical Population: Prevalence and Implications for Surgical Outcomes.

BACKGROUND: Food insecurity is defined as having limited or uncertain availability of nutritionally adequate food. Approximately 10.5% of U.S. households are food-insecure. Our study aimed to determine the prevalence and postoperative implications of food insecurity in a diverse group of colorectal surgery patients admitted to a hospital in an area with a higher-than-average median income. METHODS: The 6-question Household Food Security Survey was added to the colorectal surgery ERAS program preoperative paperwork. Patient demographics, comorbidities, operative parameters, length of stay, and postoperative outcomes were collected by review of electronic medical records. RESULTS: A total of 294 ERAS patients (88.8%) completed the survey over an 11-month period. Thirty-three patients (11.2%) were identified as food-insecure. Food-insecure patients were more likely to be non-white (P = .003), younger (P = .009), smokers (P = .004), chronic narcotic users (P < .001), unmarried (P = .007), and have more comorbidities (P = .004). The food-insecure population had more frequent postoperative ileus (P = .044). Hospital length of stay was significantly longer in food-insecure patients (8.6 days vs 5.4 days, P < .001). Food-insecure patients also had higher rates of >30-day mortality (P = .049). DISCUSSION: Food insecurity was found to occur in patients that lived in communities deemed both affluent and distressed. These patients had longer hospital stays and higher mortality. A food insecurity questionnaire can easily identify patients at risk. Further investigations to mitigate these complications are warranted.

Antibiotic practice and stewardship in the management of neutropenic fever: a survey of US institutions.

OBJECTIVE: To describe neutropenic fever management practices among healthcare institutions. DESIGN: Survey. PARTICIPANTS: Members of the Society for Healthcare Epidemiology of America Research Network (SRN) representing healthcare institutions within the United States. METHODS: An electronic survey was distributed to SRN representatives, with questions pertaining to demographics, antimicrobial prophylaxis, supportive care, and neutropenic fever management. The survey was distributed from fall 2022 through spring 2023. RESULTS: 40 complete responses were recorded (54.8% response rate), with respondent institutions accounting for approximately 15.7% of 2021 US hematologic malignancy hospitalizations and 14.9% of 2020 US bone marrow transplantations. Most entities have institutional guidelines for neutropenic fever management (35, 87.5%) and prophylaxis (31, 77.5%), and first-line treatment included IV antipseudomonal antibiotics (35, 87.5% cephalosporin; 5, 12.5% penicillin; 0, 0% carbapenem).We observed significant heterogeneity in treatment course decisions, with roughly half (18, 45.0%) of respondents continuing antibiotics until neutrophil recovery, while the remainder having criteria for de-escalation prior to neutrophil recovery. Respondents were more willing to de-escalate prior to neutrophil recovery in patients with identified clinical (27, 67.5% with pneumonia) or microbiological (30, 75.0% with bacteremia) sources after dedicated treatment courses. CONCLUSIONS: We found substantial variation in the practice of de-escalation of empiric antibiotics relative to neutrophil recovery, highlighting a need for more robust evidence for and adoption of this practice. No respondents use carbapenems as first-line therapy, comparing favorably to prior survey studies conducted in other countries.

Perioperative Lidocaine Infusion Reduces Opioid Use in Enhanced Recovery After Surgery Patients Undergoing Laparoscopic Colectomy.

BACKGROUND: Enhanced Recovery After Surgery (ERAS) programs have become a mainstay of modern surgical care, and efforts to decrease postoperative opioid consumption have been increasingly employed. A previous study from our institution demonstrated that ERAS protocols decreased opioid use in the first 48 hours after surgery by 61%. In the present study, a lidocaine infusion was added for postoperative pain control. The aim was to analyze the differences in opioid requirements with and without this infusion in the first 48 hours after laparoscopic colectomy in ERAS patients. METHODS: Retrospective review of patients was conducted at an academically affiliated tertiary care hospital. The population included patients undergoing elective laparoscopic colon surgery enrolled in the ERAS program with the implementation of a lidocaine drip from June 2019 to October 2019, and compared to a previous patient cohort of ERAS patients evaluated without the lidocaine drip from September 2015 to May 2018. RESULTS: The primary endpoint was postoperative opioid use in the first 48 hours based on IV morphine milligram equivalents (MME). Secondary measures included type of surgery, age, BMI, prior abdominal surgery, and prior opioid use. Median MMEs were 6.0 in the lidocaine infusion group and 12.5 in the group without lidocaine, representing a 52% reduction (p < 0.001). DISCUSSION: This study demonstrates a significant reduction in post-op opioid use in ERAS patients who receive a lidocaine infusion after laparoscopic colectomy. Further studies should focus on measures to limit the treatment side effects in order to maximize the opioid-sparing benefits of this intervention.

Central Line-Associated Bloodstream Infection in Patients With Hematologic Malignancy Receiving Parenteral Nutrition.

PURPOSE: Parenteral nutrition (PN) has been shown to be a safe method of feeding in the intensive care unit with modern infection prevention practices, but similar analysis in the hematology-oncology setting is lacking. METHODS: A retrospective analysis of 1,617 patients with hematologic malignancies admitted and discharged from the Hospital of the University of Pennsylvania during 3,629 encounters from 2017 to 2019 was undertaken to evaluate the association of PN administration with risk of central line-associated bloodstream infection (CLABSI). Proportions of mucosal barrier injury (MBI)-CLABSI and non-MBI-CLABSI were also compared between groups. RESULTS: Risk of CLABSI was associated with cancer type and duration of neutropenia but not with PN administration (odds ratio, 1.015; 95% CI, 0.986 to 1.045; P = .305) in a multivariable analysis. MBI-CLABSI comprised 73% of CLABSI in patients exposed to and 70% in patients not exposed to PN, and there was no significant difference between groups (χ2 = 0.06, P = .800). CONCLUSION: PN was not associated with increased risk of CLABSI in a sample of patients with hematologic malignancy with central venous catheters when adjusting for cancer type, duration of neutropenia, and catheter days. The high proportion of MBI-CLABSI highlights the effect of gut permeability within this population.

Use of Glucocorticoids in Patients With Cancer: Potential Benefits, Harms, and Practical Considerations for Clinical Practice.

PURPOSE: Glucocorticoids are commonly used in patients with cancer for symptom relief or as part of their anticancer treatment. Despite their frequent use, indications and dosing regimens are not exclusively evidence-based and can come with a multitude of adverse effects, some of which can be life-threatening. The objective of this review is to update our current state of knowledge on the use of glucocorticoids in adult patients with cancer. METHODS AND MATERIALS: A comprehensive literature review (1949-2022) was conducted using search terms "glucocorticoids," "corticosteroids," and "cancer." Information was organized by main concepts including indications, potential benefits, and prevention and management of common side effects of glucocorticoid therapy, in addition to appropriate dosing and taper regimens. RESULTS: Glucocorticoids can be highly effective in improving outcomes and quality of life in patients with cancer. Their uses include management of disease manifestations, symptoms, and complications of cancer treatment. The lowest effective dose should be used and treatment duration should be minimized as clinically feasible. Side effects can be minimized by careful monitoring, continued assessment of benefits versus harms, and preventative measures for expected side effects. CONCLUSIONS: This review provides general principles and practical recommendations on the use of glucocorticoids in patients with cancer. Further prospective studies on the outcomes of patients on glucocorticoids may help guide practice.

Clostridioides difficile dynamic electronic order panel, an effective automated intervention to reduce inappropriate inpatient ordering.

BACKGROUND: Ordering Clostridioides difficile diagnostics without appropriate clinical indications can result in inappropriate antibiotic prescribing and misdiagnosis of hospital onset C. difficile infection. Manual processes such as provider review of order appropriateness may detract from other infection control or antibiotic stewardship activities. METHODS: We developed an evidence-based clinical algorithm that defined appropriateness criteria for testing for C. difficile infection. We then implemented an electronic medical record-based order-entry tool that utilized discrete branches within the clinical algorithm including history of prior C. difficile test results, laxative or stool-softener administration, and documentation of unformed bowel movements. Testing guidance was then dynamically displayed with supporting patient data. We compared the rate of completed C. difficile tests after implementation of this intervention at 5 hospitals to a historic baseline in which a best-practice advisory was used. RESULTS: Using mixed-effects Poisson regression, we found that the intervention was associated with a reduction in the incidence rate of both C. difficile ordering (incidence rate ratio [IRR], 0.74; 95% confidence interval [CI], 0.63-0.88; P = .001) and C. difficile-positive tests (IRR, 0.83; 95% CI, 0.76-0.91; P < .001). On segmented regression analysis, we identified a sustained reduction in orders over time among academic hospitals and a new reduction in orders over time among community hospitals. CONCLUSIONS: An evidence-based dynamic order panel, integrated within the electronic medical record, was associated with a reduction in both C. difficile ordering and positive tests in comparison to a best practice advisory, although the impact varied between academic and community facilities.

Severe acute respiratory coronavirus virus 2 (SARS-CoV-2) surface contamination in staff common areas and impact on healthcare worker infection: Prospective surveillance during the coronavirus disease 2019 (COVID-19) pandemic.

We prospectively surveyed SARS-CoV-2 RNA contamination in staff common areas within an acute-care hospital. An increasing prevalence of surface contamination was detected over time. Adjusting for patient census or community incidence of coronavirus disease 2019 (COVID-19), the proportion of contaminated surfaces did not predict healthcare worker COVID-19 infection on study units.

Predictive factors of first-time failure on the American Board of Colorectal Surgery certifying and qualifying examinations.

Objective: To discover if first-attempt failure of the American Board of Colon and Rectal Surgery (ABCRS) board examination is associated with surgical training or personal demographic characteristics. Methods: Current colon and rectal surgery program directors in the United States were contacted via email. Deidentified records of trainees from 2011 to 2019 were requested. Analysis was performed to identify associations between individual risk factors and failure on the ABCRS board examination on the first attempt. Results: Seven programs contributed data, totaling 67 trainees. The overall first-time pass rate was 88% (n = 59). Several variables demonstrated potential for association, including Colon and Rectal Surgery In-Training Examination (CARSITE) percentile (74.5 vs 68.0, P = 0.09), number of major cases in colorectal residency (245.0 vs 219.2, P = 0.16), >5 publications during colorectal residency (75.0% vs 25.0%, P = 0.19), and first-time passage of the American Board of Surgery certifying examination (92.5% vs 7.5%, P = 0.18). Conclusion: The ABCRS board examination is a high-stakes test, and training program factors may be predictive of failure. Although several factors showed potential for association, none reached statistical significance. Our hope is that by increasing our data set, we will identify statistically significant associations that can potentially benefit future trainees in colon and rectal surgery.

Can the American College of Surgeons National Surgical Quality Improvement Program Risk Calculator Predict Outcomes for Urgent Colectomies?

BACKGROUND: The American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) Risk Calculator (RC) predicts postoperative outcomes using 19 risk factors, including operative acuity. Acuity is defined by the calculator as emergent or elective only. The objective of this study is to evaluate the RC's accuracy in urgent (nonelective/nonemergent) cases. METHODS: This is a retrospective review of the NSQIP data for patients who underwent urgent colectomies at a single tertiary care center over a 4-year period. Each urgent case was entered into the RC as both elective and emergent, and predicted outcomes were compared to actual postoperative outcomes. Receiver operating characteristic (ROC) curves were used when sufficient statistical power was present and the area under the curve (AUC) was calculated. RESULTS: A total of 301 urgent colectomy patients were evaluated, representing 19% of all colectomies performed at our institution during the study period. Of the 15 possible postoperative outcomes, the RC showed high predictive value only for mortality (AUC elective .8467; emergent .8451) and discharge to a nursing/rehabilitation facility (AUC elective .8089; emergent .8105). The RC showed no predictive value for 6 outcomes and the remainder lacked statistical power to draw conclusions. DISCUSSION: While the calculator predicted mortality and discharge to a nursing/rehabilitation facility, it did not accurately predict complications for urgent colectomies. Future versions of the calculator should focus on improving the predictive value by including urgent cases as a separate category.

Healthcare microenvironments define multidrug-resistant organism persistence.

BACKGROUND: Multidrug-resistant organisms (MDROs) colonizing the healthcare environment have been shown to contribute to risk for healthcare-associated infections (HAIs), with adverse effects on patient morbidity and mortality. We sought to determine how bacterial contamination and persistent MDRO colonization of the healthcare environment are related to the position of patients and wastewater sites. METHODS: We performed a prospective cohort study, enrolling 51 hospital rooms at the time of admitting a patient with an eligible MDRO in the prior 30 days. We performed systematic sampling and MDRO culture of rooms, as well as 16S rRNA sequencing to define the environmental microbiome in a subset of samples. RESULTS: The probability of detecting resistant gram-negative organisms, including Enterobacterales, Acinetobacter spp, and Pseudomonas spp, increased with distance from the patient. In contrast, Clostridioides difficile and methicillin-resistant Staphylococcus aureus were more likely to be detected close to the patient. Resistant Pseudomonas spp and S. aureus were enriched in these hot spots despite broad deposition of 16S rRNA gene sequences assigned to the same genera, suggesting modifiable factors that permit the persistence of these MDROs. CONCLUSIONS: MDRO hot spots can be defined by distance from the patient and from wastewater reservoirs. Evaluating how MDROs are enriched relative to bacterial DNA deposition helps to identify healthcare micro-environments and suggests how targeted environmental cleaning or design approaches could prevent MDRO persistence and reduce infection risk.

Spatial and temporal effects on severe acute respiratory coronavirus virus 2 (SARS-CoV-2) contamination of the healthcare environment.

BACKGROUND: The spatial and temporal extent of severe acute respiratory coronavirus virus 2 (SARS-CoV-2) environmental contamination has not been precisely defined. We sought to elucidate contamination of different surface types and how contamination changes over time. METHODS: We sampled surfaces longitudinally within COVID-19 patient rooms, performed quantitative RT-PCR for the detection of SARS-CoV-2 RNA, and modeled distance, time, and severity of illness on the probability of detecting SARS-CoV-2 using a mixed-effects binomial model. RESULTS: The probability of detecting SARS-CoV-2 RNA in a patient room did not vary with distance. However, we found that surface type predicted probability of detection, with floors and high-touch surfaces having the highest probability of detection: floors (odds ratio [OR], 67.8; 95% credible interval [CrI], 36.3-131) and high-touch elevated surfaces (OR, 7.39; 95% CrI, 4.31-13.1). Increased surface contamination was observed in room where patients required high-flow oxygen, positive airway pressure, or mechanical ventilation (OR, 1.6; 95% CrI, 1.03-2.53). The probability of elevated surface contamination decayed with prolonged hospitalization, but the probability of floor detection increased with the duration of the local pandemic wave. CONCLUSIONS: Distance from a patient's bed did not predict SARS-CoV-2 RNA deposition in patient rooms, but surface type, severity of illness, and time from local pandemic wave predicted surface deposition.

Certain Rooms in Intensive Care Units May Harbor Risk for Clostridioides difficile Infection.

Abstract Background: Clostridioides difficile infection (CDI) is a common and sometimes life-threatening illness. Patient-, care-, and room hygiene-specific factors are known to impact CDI genesis, but care provider training and room topography have not been explored. We sought to determine if care in specific intensive care unit (ICU) rooms asymmetrically harbored CDI cases. Patients and Methods: Surgical intensive care unit (SICU) patients developing CDI (July 2009 to June 2018) were identified and separated by service (green/gold). Each service cared for their respective 12 rooms, otherwise differing only in resident team composition (July 2009 to August 2017: green, anesthesia; gold, surgery; August 2017 to June 2018: mixed for both). Fixed/mobile room features and provider traffic in three room zones (far/middle/near in relation to the toilet) were compared between high-/low-incidence rooms using observation via telecritical care video cameras. Results: Seventy-four new CDI cases occurred in 7,834 consecutive SICU admissions. In period one, green CDI cases were almost double gold cases (39 vs. 21; p = 0.02) but were similar in period two in which trainee service allocation intermixed. High-incidence rooms had closer toilet-to-intravenous pole proximity than low-incidence rooms (7.7 + 1.8 feet vs. 3.9 + 1.5 feet; p = 0.02). High-incidence rooms consistently housed mobile objects (patient bed, table-on-wheels) farther away from the toilet. Although physician time spent in each zone was similar, nurses spending more than 15 minutes in-room more frequently stayed in the far/middle zones in high-incidence rooms. Conclusions: Distinct SICU room features relative to toilet location and bedside clinician behaviors interact to alter patient CDI acquisition risk. This suggests that CDI risk occurs as a structural aspect of ICU care, offering the potential to reduce patient risk through deliberate room redesign.

SARS-CoV-2 RNA persists on surfaces following terminal disinfection of COVID-19 hospital isolation rooms.

We evaluated the effect of terminal cleaning on SARS-CoV-2 RNA contamination of COVID-19 isolation rooms in an acute care hospital. SARS-CoV-2 RNA was detected on 32.1% of room surfaces after cleaning; the odds of contamination increased with month. The prevalence of elevated high-touch surface contamination was lower in terminally cleaned rooms than patient-occupied rooms.

Each section highlights three critical healthcare epidemiology research questions with detailed description provided in supplementary materials. This research agenda calls for translational studies from laboratory-based basic science research to well-designed, large-scale studies and health outcomes research. Research gaps and challenges related to nursing homes and social disparities are included. Collaborations across various disciplines, expertise and across diverse geographic locations will be critical.

Opioid Requirements in Laparoscopic Colectomies: Do Enhanced Recovery After Surgery Protocols Make a Difference?

BACKGROUND: With the growing opioid epidemic and recent focus on the quantity of opioids prescribed at discharge after surgery, enhanced recovery pathways provide another tool to counteract this epidemic. The aim of this current study is to analyze the differences in opioid requirements and pain scores in the immediate postoperative period for patients who underwent laparoscopic colectomies before and after the implementation of enhanced recovery after surgery (ERAS) protocols. MATERIALS AND METHODS: This study is a retrospective review of patients and was conducted at an academically affiliated tertiary care hospital. In patients undergoing elective laparoscopic colectomies before December 1, 2013-July 31, 2015 and after September 1, 2015-May 31, 2018, the implementation of enhanced recovery pathways was included. The primary end point was opioid consumption from the end of surgery until 48 hours after surgery. Secondary end points included pain scores, surgery length of time, and hospital length of stay after surgery. RESULTS: A total of 242 patients (122 pre- and 120 postimplementation) were analyzed. Patient characteristics were similar between groups. Pain scores were higher in the preimplementation patients for postoperative day (POD) 0 scores (P = .019). There was a decrease in the morphine milligram equivalents (MME) on POD 0-2 for the postimplementation patients. This decrease resulted in a 61% reduction in opioid requirements after implementation of ERAS protocols (32 vs. 12.5 MME, P < .0001). DISCUSSION: Enhanced recovery after surgery protocols can reduce opioid requirements after elective laparoscopic colectomies without negatively affecting pain scores.
