However, there have not been any clinical studies to support that the use of alcohol-based hand hygiene products results in an increased incidence of CDI. For example, Thompson et al demonstrated how the Medicare Case Mix Index, a summary metric calculated at the hospital level and reflecting clinical complexity and resource consumption of patients within a hospital, could further explain variation across hospital CDI rates over and above the existing model [24]. What are the best treatments for a second or greater episode of recurrent CDI in children? Table 3 lists these methods in decreasing order of analytical sensitivity. However, sporicidal agents have not been associated with reductions in CDI in nonoutbreak settings [86, 88]. Hence, it may be appropriate to monitor trough serum concentration in such circumstances to rule out drug accumulation. Yes. C. difficile was suppressed to undetectable levels in stool samples from most patients by the time diarrhea resolved (mean, 4.2 days) in a prospective study of 52 patients [95]. This protocol is to support public health investigations conducted by interested institutions and jurisdictions. Limited clinical data were collected (all patients had diarrhea but stool frequency was not known) and outcomes were assessed for 6522 inpatients who were stratified into 3 groups as follows: CCNA positive (group 1; n = 435), TC positive but CCNA negative (group 2; n = 207), and negative by both methods (group 3; n = 5880). No. The effectiveness of increased frequency of testing is substantially diminished if IPC measures are not maintained. Thank you for submitting a comment on this article. Survival analysis by time-to-preprocedural positive COVID-19 test after receiving first dose of vaccination, by total doses received. The frequency of C. difficile acquisition on gloved hands of healthcare personnel after skin contact with these patients was 69%. For activities outside of the submitted work, S. J. has served on the advisory board member for Bio-k+, Synthetic Biologics, Summit, Therapeutics, and CutisPharma; has served on Pfizer’s data and safety monitoring board for vaccine study; and has received payment for lectures from Merck. All persons can reduce the risk to themselves and others by wearing a mask, practicing physical distancing, washing their hands often, and taking other prevention measures. The utility of performing a confirmatory test with a second antigen test (either with the same platform or a different platform) is not known; repeating the test using antigen platforms might not be helpful if there are concerns about operator error contributing to false-positive results.

HCP and patients who are currently admitted to the facility or were transferred to another healthcare facility should be prioritized for notification. Daily disinfection of high-touch surfaces using a peracetic acid-based disinfectant was also shown to reduce contamination of healthcare workers’ hands [265]. The studies with the greatest influence on the results of the meta-analyses had a CDI incidence 7–20 times higher in the placebo arms than would otherwise be expected based on the patient population studied, potentially biasing the results to benefit of the probiotic [301, 302]. Clinical cure superiority was also observed in 69 patients with severe disease given vancomycin (97%) compared to metronidazole (76%; P = .02). The use of gowns as part of Contact Precautions in the context of MDROs has been implemented primarily to reduce the risk of transmission to other patients rather than to protect healthcare personnel (HCP). Based on data from the CDC’s Emerging Infections Program (EIP) [26] population-based surveillance system in 2011, the estimated number of incident CDI cases in the United States was 453000 (95% confidence interval [CI], 397100–508 500), with an incidence of 147.2 (95% CI, 129.1–165.3) cases/100000 persons [6]. There are at least 12 available commercial platforms that detect a variety of gene targets including tcdA, tcdB, and 16S ribosomal RNA (rRNA). M. B. reports personal fees from DiaSorin Molecular as an advisory board member, outside the submitted work. What are the most effective transmission prevention strategies (ie, environmental management and isolation) to prevent CDI in inpatient settings? All of these alternatives will provide equivalent or higher protection than N95 respirators when properly worn. In addition, use of donor stool introduces the potential for transmission of resistant organisms and blood-borne pathogens, necessitating donor-screening protocols. What should healthcare providers (HCP) do outside of work to prevent transmission of SARS-CoV-2, the virus that causes COVID-19? The. If a resident is asymptomatic and declines testing at the time of facility-wide testing, decisions on placing the resident on Transmission-Based Precautions for COVID-19 or providing usual care should be based on whether the facility has evidence suggesting SARS-CoV-2 transmission (i.e., confirmed infection in HCP or nursing-home onset infection in a resident).

This study provides the most compelling evidence to date for the significant effect of isolating carriers. Dubberke et al used a clinical definition of ≥3 diarrheal bowel movements (type 6 or 7 stool on the Bristol Stool Chart) [173] in the 24 hours preceding stool collection, or diarrhea plus patient-reported abdominal pain or cramping. Additional agents with inadequate evidence to recommend treatment of an initial CDI episode include rifaximin, tigecycline, and bacitracin (Table 7). A recurrent case is defined as an episode of symptom onset and positive assay result following an episode with positive assay result in the previous 2–8 weeks. During respirator shortages, care should be taken to ensure that N95 respirators are reserved for situations where respiratory protection is most important, such as performance of aerosol-generating procedures on patients with suspected or confirmed COVID-19 infection. No single methodology (“no-touch” or otherwise) appears to be superior in regard to reductions in CDI incidence. Despite significant efforts leveraging nonpharmacologic interventions such as use of face masks, physical distancing, community stay-at-home measures, quarantine, and isolation, spread has continued throughout much of the world. The highest risk of CDI (7- to 10-fold increase) appears to be during and in the first month after antibiotic exposure [99]. To date there are no prospective, randomized studies of secondary prophylaxis of CDI to guide recommendations, but if the decision is to institute CDI prevention agents, it may be prudent to administer low doses of vancomycin or fidaxomicin (eg, 125 mg or 200 mg, respectively, once daily) while systemic antibiotics are administered. As part of routine practice, HCP should also be using additional engineering controls for source control, when applicable (e.g., smoke evacuation devices). Should data from infants <12 months of age be included in laboratory-based surveillance and reporting? One study showed a decreased risk for those whose previous CDI episode was itself a recurrent CDI episode, but not for those following a primary CDI episode [356]. In addition to members of both IDSA and SHEA, representatives from the American Society for Health-Systems Pharmacists (ASHP), the Society of Infectious Diseases Pharmacists (SIDP), and the Pediatric Infectious Diseases Society (PIDS) were included. In the Curry et al study, environmental transmission may have occurred in 4 of 61 incident healthcare-associated CDI cases [75]. As a practical measure, we continue to recommend WBC count and serum creatinine as supportive clinical data for the diagnosis of severe CDI, but have changed the creatinine value to an absolute value as opposed to the previous comparison to baseline values, which are not always available [322] (Table 1). At this time, available evidence demonstrates no indication of COVID-specific harm from these agents. The incidence of CDI decreased significantly after this intervention compared with the preintervention period and the lower incidence was sustained for at least 1 year after the study terminated. While none of the patients had CDI-related complications, one patient had CDI as a contributing factor to death. However, cloth face coverings are not personal protective equipment (PPE) and should not be used instead of a respirator or a facemask to protect a healthcare worker. When a false-positive test is suspected, nursing homes and health departments should also review and gather the following information: In most instances, CDC guidancepdf icon currently recommends performing confirmatory testing when asymptomatic individuals are antigen positive. However, the environmental contamination of C. difficile was not measured in this study, and the results were not reproducible on other units with low CDI incidence. Cloth masks are not PPE and should not be used alone to protect against splashes and sprays, such as when used while treating patients on Droplet Precautions. For activities outside of the submitted work, K. C. has received research grants from GenePOC, Accelerate, and BD Diagnostics; has received royalties from McGraw-Hill and ASM Press; and has received travel expenses as board member with ASM. Daily sporicidal disinfection can be effective at reducing C. difficile environmental contamination and has been associated with reductions in CDI in outbreak settings in conjunction with other interventions to prevent CDI. Residents and healthcare personnel (HCP) with signs or symptoms of COVID-19, Residents and HCP who are asymptomatic in response to an outbreak in the facility (i.e., a new SARS-CoV-2 infection in any HCP or any SARS-CoV-2 infection in a resident), All residents and HCP once and serially test HCP who are asymptomatic in facilities without an outbreak as. Using multilocus variable number of tandem repeats analysis, Curry et al found that 29% of CDI cases in a hospital were associated with asymptomatic carriers, compared to 30% that were associated with CDI patients [75]. Based on their risk assessment, safe work practices, including engineering controls that reduce the release of infectious material, administrative controls, and use of personal protective equipment (PPE) should be implemented at the point of care according to CDC guidelines and standards of practice for the activity performed. All other authors report no potential conflicts.

If still wearing their original respirator or facemask and eye protection, the transporter should take care to avoid self-contamination when donning the remainder of the recommended PPE. Note: Serologic testing should not be used to establish the presence or absence of SARS-CoV-2 infection or reinfection. There were 11 CDI-related deaths among the toxin-positive/PCR-positive patients, one death among the PCR alone cohort, and no deaths among the group with negative tests (P < .001). To decrease C. difficile spore contamination, one hospital found, over the course of several interventions that included terminal disinfection with bleach, use of fluorescent markers to assess cleaning adequacy, use of an automated ultraviolet radiation device, and a dedicated team focused on daily cleaning of rooms housing patients with CDI, that the latter intervention was clearly the most effective at removing viable C. difficile spores from the environment [254]. Summary odds ratios (ORs) were presented for incident cases of CDI (OR, 1.74; 95% CI, 1.47–2.85) as well as recurrent CDI (OR, 2.51; 95% CI, 1.16–5.44). There is also the potential for organisms in probiotic formulations to cause infections in hospitalized patients [303–305]. No. If shortages exist, N95 or equivalent or higher-level respirators should be prioritized for procedures involving higher risk techniques (e.g., that generate potentially infectious aerosols) or that involve anatomic regions where viral loads might be higher (e.g., nose and throat, oropharynx, respiratory tract).

Notably, the number and frequency of diarrheal stools required to justify CDI testing have declined over the past 40 years. Isolation and precautions may be discontinued for persons with COVID-19 10 days after symptom onset (the date on which symptoms first began, including non-respiratory symptoms), provided their fever has resolved for at least 24 hours, without the use of fever-reducing medications, and their other symptoms have improved. Facilities should ensure adherence to appropriate IPC measures in outbreak settings, including use of Transmission-Based Precautions for the care of all residents (even those who have negative tests) on affected units (or facility-wide, if cases are widespread). However, at the time of resolution of diarrhea, skin and environmental contamination was high at 60% and 37%, respectively. Rifaximin, however, has been more extensively studied as an adjunctive postvancomycin treatment regimen in patients with recurrent CDI (see section XXXI). Can clinical predictors of severe CDI in children be identified? What drugs, dosages, and duration? Those who live in or have recently been to areas with sustained transmission may also be at higher risk of infection. For example, inpatient psychiatric care includes communal experiences and group activities that may need to continue. At this time, whether you have had COVID-19 or not, the best ways to prevent infection are to wear a mask in public places, stay at least 6 feet away from other people, frequently wash your hands with soap and water for at least 20 seconds, and avoid crowds and confined spaces. V. What is the recommended CDI surveillance strategy for pediatric institutions? For information about the application of EPA List N disinfectantsexternal icon with electrostatic sprayers and foggers, refer to the EPA’s Frequent Questions about Disinfectants and Coronavirus (COVID-19external icon). Results across both sponsored and nonsponsored studies should be considered to select a relatively more sensitive EIA for general use [174]. We attempted to adjust for confounding factors through an adjusted analysis and observed that the strength of association between vaccine receipt and a decline in test positivity only strengthened. Care should also be taken to prevent contamination of hands when removing gloves. As noted above, fidaxomicin was not approved for use in patients <18 years of age at the time of this writing. Testing for CDI was performed on diarrheal (84%) and nondiarrheal (16%) stool samples in patients in whom it may be very difficult to interpret the true clinical significance of diarrhea, namely cancer patients undergoing intensive chemotherapy [183]. Testing for recurrent CDI should ideally include toxin detection, as persistence of toxigenic C. difficile can occur commonly after infection. UVGI can be used as a supplemental treatment for disinfection of air in HVAC systems or above people in occupied spaces (upper-room or upper-air systems) and for supplemental disinfection of surfaces following routine cleaning and disinfection. The symptom-based strategy is intended to replace the need for repeated testing. Aside from funding, we advise the Australian Government and facilitate networking in the research community by bringing academics and industry together. However, the positive predictive value of NAATs for CDI is low to moderate depending upon disease prevalence and the limit of detection of the assay. Unrecognized SARS-CoV-2 is most often introduced into a nursing home by asymptomatic healthcare personnel (HCP) or visitors with COVID-19 who work at or visit the nursing home, rather than residents. XXVII. Similarly, there are inherent limitations in all surveillance adjusting for the disease risk in the surveyed population. It is important to realize that guidelines cannot always account for individual variation among patients. In summary, there is a theoretical possibility for alcohol-based hand hygiene products to increase the incidence of CDI because of their inability to eliminate C. difficile spores from the hands. However, since 2000, additional randomized, placebo-controlled trials have shown that oral vancomycin was superior to metronidazole (Table 6) [170, 188]. A systematic evidence-based approach was adopted for the guideline questions and population, intervention, comparator, outcome (PICO) formulations, the selection of patient-important outcomes, as well as the literature searches and screening of the uncovered citations and articles. Recurrent CDI results from the same or a different C. difficile strain but, in clinical practice, it is impossible to distinguish these 2 mechanisms [341, 342]. Although NAATs for C. difficile detection in stool began to appear in the literature in the early 1990s, the first US Food and Drug Administration (FDA)–cleared platform was not available in the United States until 2009 [174]. The incidence was highest among those aged ≥65 years (627.7) and was greater among females and whites. The patient and the treating physician must also decide the route of FMT instillation, taking into consideration individual preferences and recognizing that the rate of success varies with the route of instillation [373]. Therefore, before and after providing care for a patient with CDI, it is recommended to preferentially use soap and water over alcohol-based products alone for hand hygiene in CDI-hyperendemic (sustained high rates) or outbreak settings. The National Institutes of Health has published interim guidelines for the medical management of COVID-19external icon prepared by the COVID-19 Treatment Guidelines Panel. Resolution of diarrhea at end of treatment without recurrence 25 days after treatment (sustained clinical response) was superior for fidaxomicin (71%) compared to vancomycin (57%) (RR, 1.2; 95% CI, 1.1–1.4). Single-use disposable equipment should be used to prevent CDI transmission. How do spores interact with the human gastrointestinal immune system? Fulminant CDI, previously referred to as severe, complicated CDI, may be characterized by hypotension or shock, ileus, or megacolon. Thus far, only one study of NTD use has shown a decrease in patient infection rates, the. Based on current evidence, scientists believe that persons with mild to moderate COVID-19 may shed replication-competent SARS-CoV-2 for up to 10 days following symptom onset, while a small fraction of persons with severe COVID-19, including immunocompromised persons, may shed replication-competent virus for up to 20 days.

When should multiplex PCR test platforms for enteric pathogens be used for diagnosis of CDI? Bauer et al found that fever (>38.5°C), WBC count >15 × 109/L, and creatinine >1.5 mg/dL correlated with treatment failure and that timing of measurement with respect to the positive stool C. difficile assay influenced the values of the variables [319]. However, whether as a risk factor for primary or recurrent disease, the choice of control group in such epidemiologic studies is important. The National Institutes of Health recently published guidelines on prophylaxis use for COVID-19 and testing and management of COVID-19 patients. It is in this context of CDI remaining a major public health problem, undermining both patient safety and the efficiency and value of healthcare delivery, that the 2010 recommendations are now revised and updated. As stated in the MRSA, GRMRSA, and ZAF-10, SAHPRA is responsible for clinical trial oversight, approval, and inspections in South Africa. All authors have submitted the ICMJE Form for Disclosure of Potential Conflicts of Interest. Recommendations for testing of residents who are asymptomatic in nursing homes is generally reserved for situations such as response to an outbreak in the facility (i.e., a new SARS-CoV-2 infection in any HCP or any SARS-CoV-2 infection in a resident) or evaluation of a resident who has had close contact with someone with confirmed SARS-CoV-2 infection. Once availability of supplies is reestablished, the guidance states that the use of N95 and higher level respirators should resume. The daily increase in the risk of C. difficile acquisition during hospitalization suggests that duration of hospitalization may be a proxy for the duration and degree of exposure to the organism, likelihood of exposure to antibiotics, and severity of underlying illness [46, 74, 98]. Are clinically recovered persons infectious to others if they test persistently or recurrently positive for SARS-CoV-2 RNA? Additional information about this scenario is available here. Other risk factors for CDI include gastrointestinal surgery [102] or manipulation of the gastrointestinal tract, including tube feeding [110]. Stress the importance of obtaining emergency care if needed. What is the best method to identify patients at risk of primary or recurrent CDI? The relative contribution of each of these is not known for SARS-Co-V-2. To provide thorough transparency, IDSA requires full disclosure of all relationships, regardless of relevancy to the guideline topic [14]. What are the best treatments of fulminant CDI? If a previously infected person has clinically recovered but later experiences symptoms consistent with COVID-19, should the person be isolated again and tested for SARS-CoV-2? If that person again tests positive by RT-PCR, should they be managed as potentially infectious to others, and isolated again for COVID-19? When used for source control, medical facemasks, including cloth masks that are used to cover medical facemasks to improve the fit, may be used for the duration of a shift unless they become soiled, damaged, or hard to breathe through; medical facemasks, including cloth masks, used for source control should be removed and discarded (or, Clinicians are able to access laboratory testing through state and local public health laboratories, as well as commercial and clinical laboratories across the country. The most important modifiable risk factor for the development of CDI is exposure to antibiotic agents. The criteria used were based on expert opinion and had not been validated at the time. Healthcare facilities should refer to that guidance and implement the recommended strategies to optimize their current supply of gowns. Garg S, Kim L, Whitaker M, et al. XXV. For EPA registered detergent disinfectants, refer to the label to determine if the product is a one-step or multiple-step product, and follow the product label instructions for use. Another limitation was the relatively low prevalence of true disease in the tested population based upon the positivity rate of either the CCNA (5.9%) or TC (8.3%); this reflected national endemic rates of CDI at that time.

The transfer of pathogens from environmental surfaces is largely due to hand contact with the surface (e.g., frequently touched surfaces). For the second investigation, patients were interviewed prospectively and among the 350 patients with 365 unique episodes of potential CDI, 39% did not have sufficient diarrhea to warrant testing and were not further analyzed [172]. The majority of pediatric studies have evaluated the incidence of CDI-related hospitalizations among multicenter cohorts of hospitalized children [126–128]. Structured data collection forms were used to collect information prospectively regarding complications and whether patients with positive tests met the case definition. One-step disinfection product and process combine cleaning and disinfection of a noncritical environmental surface or item into a single step. Conversely, the GDH and NAATs detected the most positive samples.

Discontinuation of inciting antibiotic agent(s) as soon as possible should always be considered as their continued use has been shown to decrease clinical response and increase recurrence rates [292, 306]. Should these platforms exclude C. difficile or should the C. difficile result be hidden given the availability of specific C. difficile diagnostics and the consideration of the different indications for testing (eg, traveler’s diarrhea, hospital onset, antibiotic-associated diarrhea)? Additional isolation techniques (contact precautions, private rooms, and cohorting of patients with active CDI) have been used for control of outbreaks, with variable success [207, 214, 215]. This is especially important if ileus is present as this may impair the delivery of orally administered vancomycin to the colon, but intravenously administered metronidazole is likely to achieve therapeutic concentrations in an inflamed colon. Should angiotensin-converting enzyme inhibitors (ACE-Is) or angiotensin receptor blockers (ARBs) be stopped in patients with COVID-19? Should diverting loop ileostomy be the preferred procedure over colectomy in this setting? CDC has posted interim guidance for risk assessment and work restrictions for HCP with potential exposure to SARS-CoV-2. Where can I find detailed information on cleaning and disinfection?

First, as PPE to protect a healthcare worker’s nose and mouth from exposure to splashes, sprays, splatter, and respiratory secretions, such as when treating patients on Droplet Precautions. In nursing homes with outbreaks, most cases are identified within the first two weeks of diagnosing the first new case.
