RESUMEN

The objective of this study was to determine the risk factors associated with Elizabethkingia anophelis infection in neonates admitted to a tertiary care neonatal intensive care unit (NICU). A case-control study was undertaken as part of the outbreak investigation for E. anophelis sepsis in a tertiary care NICU in South India. Thirty-eight neonates with E. anophelis bloodstream infection (BSI) between January 2021 and February 2022 were enrolled as cases, and 38 neonates symptomatic with other BSIs, were selected as controls, and risk factors analysed. The 38 cases were relatively stable neonates, likely to be admitted to level 1 and level 2 NICU, unlike the controls, who were sicker and required level 3 NICU care. Only a third of neonates with Elizabethkingia sepsis had traditional risk factors like central lines, need for respiratory support or perinatal risk factors. Multiple logistic regression analysis revealed that neonates with E. anophelis infection were more likely to be stable and on only enteral feeds, cared in level 1 or 2 of the NICU. This observation, combined with isolation of Elizabethkingia meningosepticum from breast pumps earlier, led us to autoclave the feeding vessels and milk containers along with provision of hot water for cleaning breast pumps, and adoption of general infection control measures, after which incident cases declined. Sanger sequencing of 10 representative isolates obtained from the neonates showed 100% sequence identity to E. anophelis. Infection due to E. anophelis affects relatively stable neonates without traditional risk factors for sepsis. Adherence to asepsis routines and housekeeping protocols helps to prevent the spread of infection.


Elizabethkingia anophelis is an emerging pathogen causing infection in neonates. In the present case­control study, we found that E. anophelis was more likely to infect otherwise healthy neonates, on enteral nutrition, without the traditional risk factors for sepsis. Mortality was 23.7% (9/38). About 55.3% (21/38) had meningitis and 23.8% (9/38) had hydrocephalus. Additionally, 76% isolates were multi-drug resistant, with the isolates showing highest susceptibility to minocycline (100%) and levofloxacin (97.8%). Source identification was not possible even after multiple rounds of extensive environmental testing, but it is possibly related to contamination of water and/or milk sources. Interventions addressing the same led to a dramatic decline in the infection rates, though occasional infection without clustering continues to occur. Sanger sequencing of 10 representative isolates confirmed sequence identity to E. anophelis.

RESUMEN

PURPOSE: Surgical site infection (SSI) is one of the frequent healthcare associated infections linked with significant morbidity, prolonged hospitalization, and death. SSI can be reduced by implementation of customized care bundle components as per standard guidelines. Hence this study was undertaken with the objective to implement care bundle in patients undergoing elective gastrointestinal surgeries and assess their impact on SSI rate. METHODS: The study was an interventional study conducted in the department of surgical gastroenterology for 8 months. Sample size was calculated to be 196 and only elective surgeries are included. CDC NHSN 2023 guidelines are used for surveillance of SSI and global guidelines for prevention of SSI was used for preparation of list of pre-operative, intraoperative and post-operative care bundle components and were implemented before the start of the study. RESULTS: Overall SSI rate and compliance to SSI care bundle in this study are 13.8% and 28.6%, respectively. When compared with the baseline SSI rate of 19.4%, there is reduction of 28.9% in SSI rate after the implementation of care bundle. Escherichia coli (54.2%) is the most commonly isolated organism. Care bundle non-compliant surgeries are associated with 2.3 times (relative risk-2.3) increased risk of SSI. There is fluctuating trend in compliance of care bundle and SSI rates across months. CONCLUSION: This study shows the importance of implementation of set of care bundle for prevention of SSI which can be customized and adapted for reducing SSI.

RESUMEN

BACKGROUND: A care bundle comprises a set of evidence-based practices in patient care that are grouped together with the assumption that these practices when performed together will result in better clinical outcomes than when these practices are performed separately. Care bundles for devices when implemented effectively can bring about a reduction in device associated infection rates. METHODS: The study was conducted in three phases, 1 month pre-interventional and interventional phases and 11 months of post-interventional phase in a critical care unit. Compliance to care bundles were recorded by direct observation during daily audit rounds. An educational intervention addressing the healthcare workers regarding bundle care approach was conducted and supplemented with bedside "audit and feedback" during the interventional phase. Audit was conducted in the post-interventional period to study the trend of device associated infections and compliance rates. RESULTS: An increasing trend of month-wise compliance rates to the device care bundles were observed. The month-wise Ventilator Associated Events rates showed a decreasing trend. In the post-interventional phase, the average Catheter-associated Urinary Tract Infection, Central Line Associated Bloodstream Infection and Ventilator Associated Events rates showed a reduction from their respective baseline rates for the study setting. CONCLUSIONS: An educational intervention targeted at the healthcare workers along with daily audit of care bundle practices in the critical care setting led to an increase in the compliance to device care bundles and a reduction in the incidence of Catheter-associated Urinary Tract Infection, Central Line Associated Bloodstream Infection and Ventilator Associated Events rates in the critical care setting.

RESUMEN

OBJECTIVE: To assess the efficacy of an electronic infrared tap with voice reinforcement to improve hand hygiene compliance among health care workers. METHOD: This pre-post intervention study used an automated electronic infrared tap with voice reinforcement as intervention in the neonatal intensive care unit (NICU) and the pediatric intensive care unit (PICU). Hand hygiene adherence rates of health care workers were monitored using a video camera. RESULTS: A total of 2718 hand hygiene events were observed. Baseline rates of hand hygiene (complete or partial adherence rates) were 86.9% in NICU and 81.2% in PICU, that improved to 94.9% for NICU and 92.9% for PICU post-intervention (P=0.001). CONCLUSION: Use of an electronic infrared (EIR) tap with voice reinforcement in handwashing stations of NICU and PICU improved hand hygiene compliance among health care workers.

RESUMEN

Background: Ventilator-associated pneumonia (VAP) is one of the most frequent hospital-acquired infections, which develops in mechanically ventilated patients after 48 hours of mechanical ventilation. The purpose of this study was to determine the incidence rate, various risk factors, microbiological profile, and outcome of early- vs late-onset ventilator-associated pneumonia (VAP) in medical intensive care unit (MICU). Materials and methods: This prospective study was conducted on 273 patients admitted to the MICU in JIPMER, Puducherry, from October 2018 to September 2019. Results: The incidence of VAP was 39.59 per 1000 ventilation days of MICU patients (93/273). Of these, 53 (56.9%) patients had early-onset VAP and 40 (43.1%) had late-onset VAP. Multiple logistic regression analysis showed that steroid therapy, supine head position, coma or impaired unconsciousness, tracheostomy, and re-intubation were found to be independent predictors of early- and late-onset VAP, respectively. Most cases of VAP were caused by Gram-negative bacteria (90.6%), with nonfermenters contributing to 61.8%. The most frequent pathogens causing early-onset VAP were Acinetobacter baumannii (28.9%) and Pseudomonas aeruginosa (20.6%), while in late-onset VAP, A. baumannii (32.9%) and Klebsiella pneumoniae (21.9%) were the most common. Maximum death rate was seen in patients infected with Escherichia coli (50%) and Stenotrophomonas maltophilia (38.5%). There was no significant association between the presence of VAP and mortality among the studied population. Conclusion: The incidence of VAP in our study was high. There were no significant differences in the prevalence of pathogens associated with early-onset or late-onset VAP. Our study shows that early-onset and late-onset VAP have different risk factors, highlighting the need for developing different preventive and therapeutic strategies.

RESUMEN

INTRODUCTION: It is unclear if serum procalcitonin (PCT) estimated at sepsis suspicion can help detect culture-positive sepsis in neonates. We evaluated the diagnostic performance of PCT in culture-positive sepsis in neonates. METHODS: This was a prospective study (February 2016 to September 2020) conducted in four level-3 units in India. We enrolled neonates suspected of sepsis in the first 28 days of life. Neonates with birth weight <750 g, asphyxia, shock, and major malformations were excluded. Blood for PCT assay was drawn along with the blood culture at the time of suspicion of sepsis and before antibiotic initiation. The investigators labeled the neonates as having culture-positive sepsis or "no sepsis" based on the culture reports and clinical course. PCT assay was performed by electrochemiluminescence immunoassay, and the clinicians were masked to the PCT levels while assigning the label of sepsis. Primary outcomes were the sensitivity, specificity, and likelihood ratios to identify culture-positive sepsis. RESULTS: The mean birth weight (SD) and median gestation (IQR) were 2,113 (727) g and 36 (32-38) weeks, respectively. Of the 1,204 neonates with eligible cultures, 155 (12.9%) had culture-positive sepsis. Most (79.4%) were culture-positive within 72 h of birth. The sensitivity, specificity, and positive and negative likelihood ratios at 2 ng/mL PCT threshold were 52.3% (95% confidence interval: 44.1-60.3), 64.5% (60.7-68.1), 1.47 (1.23-1.76), and 0.74 (0.62-0.88), respectively. Adding PCT to assessing neonates with 12.9% pretest probability of sepsis generated posttest probabilities of 18% and 10% for positive and negative test results, respectively. CONCLUSION: Serum PCT did not reliably identify culture-positive sepsis in neonates.

RESUMEN

Background In the era of increased antimicrobial resistance, there are limited therapeutic options available for the treatment of bacteremia caused by multidrug-resistant organisms (MDROs). This study aims to find out the feasibility of using ceftazidime/avibactam (CZA) as a therapeutic option for bloodstream infections caused by multidrug-resistant (MDR) Enterobacterales and Pseudomonas aeruginosa based on its susceptibility profile. Materials and methods The isolates were routinely subjected to antimicrobial susceptibility testing (AST) by an automated AST system (VITEK-2). Those isolates found as MDR (resistant to at least one drug for ≥3 antimicrobial classes) were tested against CZA by Kirby-Bauer's disk diffusion (kb-DD) method. Results A total number of 293 MDR Enterobacterales and 31 MDR P. aeruginosa isolates were included. Of these, 87.3% of isolates were found as carbapenem-resistant (CR), whereas 12.7% of isolates were found as carbapenem susceptible. About 30.6% of MDROs were susceptible to CZA. Among carbapenem-resistant organisms (CROs), CR Klebsiella pneumoniae(33.5%) is most susceptible to CZA, compared to CR P. aeruginosa(0%)and CREscherichia coli(3.2%). Among the MDR isolates that were susceptible to CZA (30.6%), the majority had poor susceptibility against other ß-lactam-ß-lactamase inhibitor (BL-BLI) agents. Among all antimicrobial agents tested against CROs, colistin (96%) was found to have the best susceptibility profile. Conclusion It is observed that CZA is an acceptable therapeutic option for the treatment of bacteremia caused by MDROs, especially CROs. Therefore, it is important for the laboratories to perform the AST for CZA if the healthcare settings intend to use CZA for the management of such "difficult-to-treat" bloodstream infections.

RESUMEN

Neonatal invasive candidiasis (NIC) has significant morbidity and mortality. Reports have shown a different profile of those neonates affected with NIC and of fluconazole-resistant Candida spp. isolates in low- and middle-income countries (LMICs) compared to high-income countries (HICs). We describe the epidemiology, Candida spp. distribution, treatment, and outcomes of neonates with NIC from LMICs enrolled in a global, prospective, longitudinal, observational cohort study (NeoOBS) of hospitalized infants <60 days postnatal age with sepsis (August 2018-February 2021). A total of 127 neonates from 14 hospitals in 8 countries with Candida spp. isolated from blood culture were included. Median gestational age of affected neonates was 30 weeks (IQR: 28-34), and median birth weight was 1270 gr (interquartile range [IQR]: 990-1692). Only a minority had high-risk criteria, such as being born <28 weeks, 19% (24/127), or birth weight <1000 gr, 27% (34/127). The most common Candida species were C. albicans (n = 45, 35%), C. parapsilosis (n = 38, 30%), and Candida auris (n = 18, 14%). The majority of C. albicans isolates were fluconazole susceptible, whereas 59% of C. parapsilosis isolates were fluconazole-resistant. Amphotericin B was the most common antifungal used [74% (78/105)], followed by fluconazole [22% (23/105)]. Death by day 28 post-enrollment was 22% (28/127). To our knowledge, this is the largest multi-country cohort of NIC in LMICs. Most of the neonates would not have been considered at high risk for NIC in HICs. A substantial proportion of isolates was resistant to first choice fluconazole. Understanding the burden of NIC in LMIC is essential to guide future research and treatment guidelines.


Our study describes neonates from low- and middle-income countries with neonatal invasive candidiasis (NIC). Most of them were outside the groups considered at high risk for NIC described in high-income countries. Candida spp. epidemiology was also different. The mortality was high (22%). Further research in these settings is required.

RESUMEN

BACKGROUND: Hand hygiene is a significant component involved in preventing transmission of health care associated infections including COVID-19. Compliance to hand hygiene among the health care workers (HCWs) requires evaluation and timely feedback. "You can't improve what you can't measure" is a famous saying and this multicentric study was designed to measure hand hygiene compliance and have birds eye view on hand hygiene compliance in COVID Intensive care units (ICUs) and wards across India. METHODS: A prospective multicentric observational study was conducted for a period of 6 months in 92 health care facility across India which included varied type of public and private hospitals. Hand hygiene audit was conducted in COVID ICU and COVID non-ICU wards in all these facilities by their HCWs using the IBHAR mobile application based on WHO's hand hygiene audit tool. Hand hygiene total adherence rate (HHTAR) and hand hygiene complete adherence rate (HHCAR) were analyzed and compared between 2 locations. Adherence rates were analyzed based on the zones, institute type, profession and for each WHO moments. RESULTS: A total of 1,61,056 hand hygiene opportunities were documented and adherence rates were recorded higher in COVID wards (HHTAR-61.4%; HHCAR-28.8%) than COVID ICUs (HHTAR-57.8%; HHCAR-25.6%). Overall, the adherence rates were observed higher in COVID wards (HHTAR- 68.1%; HHCAR-38.3%) of private hospitals, COVID wards of the west zone (HHTAR- 70.2%; HHCAR-36.8%), cleaning staffs of the COVID ward scores better compliance than all other professions in COVID ICUs and COVID wards. HHTAR was found to be the higher in moment 3 (After body fluid exposure-76.3%) followed by moment 4 (after touching patient-73.7%) done in COVID wards compared to moments done in ICUs. CONCLUSIONS: This study highlights the practice of hand hygiene in COVID care locations across India. Effective strategies need to be implemented in COVID ICUs across the facilities to improve the compliance.

RESUMEN

PURPOSE: Hand hygiene (HH), the core element in infection prevention in healthcare, especially for multidrug resistant organism's transmission. The role of HH audits and HH adherence rates in the COVID-19 pandemic, especially in resource limited settings, are yet to be established. METHODS: A nationwide multicenter study was conducted in India, involving public, private, teaching and non-teaching COVID healthcare facilities (COVID-HCFs) using the IBhar mobile application based on WHO's hand hygiene audit tool. The HH adherence rates (HHAR) such as complete HHAR (HHCAR), total HHAR (HHTAR), profession specific HHAR, WHO's 5 HH moment specific HHAR and associated variables were measured over 6 month duration (June-December 2021). RESULTS: A total of 2,01,829 HH opportunities were available and the HHCAR and HHTAR were 27.3% and 59.7%. The HHTAR was significantly higher in the west zone (72.2%), private institutes (65.6%), non-teaching institutes (67.7%), nurses (61.6%), HH moments 2 (71.8%) and 3 (72.1%), and morning shift (61.4%). The HHTAR was better in non-COVID HCFs (65.4%) than COVID-HCFs (57.8%) as well as non-COVID ICUs (68.1%) than COVID ICUs (58.7%). The HHTAR was increased from month 1 to month 6 except a small decrease in the month of December. CONCLUSIONS: The hand hygiene adherence is comparable with adherence rate during COVID-19 pandemic in western countries as well as the resource limited settings. The use of gloves during the pandemic and simplified HH techniques and their influence over the HH adherence to be studied further. The sustainable adherence rate over long duration needs to be ensured by continuing the HH audit using multimodal interventions.

RESUMEN

INTRODUCTION: In blood banking and transfusion medicine, it is of paramount importance to improve transfusion safety and provide a higher quality of product to maximize the therapeutic outcomes and minimize the risk of developing transfusion-associated complications for patients receiving a blood transfusion. MATERIALS AND METHODS: This was a cross-sectional study conducted at the department of transfusion medicine in a tertiary care hospital of South India from February 2019 to December 2020. The primary objective of the study was to assess the quality of platelet concentrates (PC) prepared by platelet-rich plasma (PRP), buffy-coat (BC), and apheresis method. A total of 760 PCs were subjected to quality assessment, among which 124 were PRP-PC, 176 were BC-PC, and 460 were single donor platelet (SDP). RESULTS: The total percentage of platelets meeting all the six quality control parameters in PRP, BC and SDP was 78.23%, 81.81%, and 89.96%, respectively. Apheresis PCs showed a significantly higher platelet concentration per µL on comparison with whole-blood-derived platelets. BC-PCs were found to be better than PRP-PC with regard to lower white blood cell (WBC) contamination (P < 0.05) and red blood cell (RBC) contamination (P < 0.01). No statistically significant difference was found with regard to platelet yield, volume, swirling, and pH. CONCLUSION: Ex vivo quality of PCs prepared by BC-PC, PRP-PC, and apheresis-PC fulfilled the desired quality control parameters. BC-PC was better than PRP-PC in terms of lesser WBC and RBC contamination and comparable in terms of volume, platelet yield, swirling, and pH. Apheresis PCs showed a higher platelet concentration per microliter on comparison with whole-blood-derived platelets; hence in a blood center where facilities for collection of apheresis product are available, SDPs should be the choice of platelet transfusion.

RESUMEN

Corynebacterium (C.) diphtheriae is the agent for a contagious infection, diphtheria. It may manifest as pharyngitis with pseudomembrane formation and cervical lymphadenopathy, cutaneous infection, or as an asymptomatic carrier. Corynebacterium (C.) diphtheriae is not an invasive organism and it remains in the superficial layers of skin lesions and respiratory mucosa. Systemic complications, such as bacteremia, are rare. We report a case of toxigenic C. diphtheriae detected from blood culture of a 1-year-old male patient with burns, who succumbed to the infection after 8 days of stay in the hospital. Patient did not have specific clinical features suggestive of diphtheria. Initial identification of C. diphtheriae was done based on culture, Albert stain findings, biochemical tests and subsequently toxigenicity testing was done by polymerase chain reaction. Although diphtheria vaccination in infancy is universally recommended since the creation of the Expanded Program on Immunization in the 1970s, there have been reports of toxigenic strains of C. diphtheriae in a considerable number of cases. Rapid and accurate identification of C. diphtheriae infection is crucial to prevent mortality. Continued surveillance for diphtheria is needed to reduce transmission and mortality rates.

RESUMEN

Introduction: The blood culture (BC) contamination was a significant problem in our hospital, especially in the emergency department (ED). The study, therefore, was undertaken to improve the BC collection in the ED. Methods: The study was conducted for 1 year divided into two phases of 6 months each: Preintervention phase and intervention phase (regular and phlebotomist groups). The interventions comprised implementing standard protocol for BC collection and conducting educational sessions. In preintervention and regular groups, the BCs were collected by interns and technicians, while dedicated phlebotomist did so in the phlebotomist group. Data were analyzed and interpreted for the contamination rate as well as compliance in adequate filling of the requisition form. Statistical Package for the Social Sciences (SPSS) version 22. A value of P < 0.005 was considered statistically significant, and P < 0.01 was considered statistically significant. Results: In the preintervention group, 13.7% of specimens were reported as contaminated which was reduced to 4.2% and 3.2% in the regular and phlebotomist group, respectively, after intervention. Compliance of health-care workers to various elements of BC collection protocol was also found to be significantly improved in the intervention phase compared to the preintervention phase (P < 0.001). Conclusions: Implementation of this multimodal intervention resulted in a drastic reduction in BC contamination and improvement in compliance to BC collection protocol and filling of various parameters in the BC requisition form, thus improving the overall effectiveness of BC testing. It was also noted that the contamination rate was further reduced by implementing dedicated phlebotomist.

RESUMEN

In view of the rising incidence of Anaerobic bacteremia(AB), the use of anaerobic blood culture bottles have been recommended in addition to the aerobic blood culture bottles. The need to perform antimicrobial susceptibility testing(AST) for anaerobes has become mandatory owing to increasing metronidazole resistance. The frequency of AB following large bowel surgery and the metronidazole susceptibility for members of the Bacteroides fragilis group were determined. The incidence of AB was found to be 16%. Seventeen obligate anaerobes were isolated in total, of which B. fragilis was the most common. Two of twelve isolates of B. fragilis were resistant to metronidazole.

RESUMEN

BACKGROUND: Postoperative infections are a common entity following elective gastrointestinal surgery among which intra-abdominal infection is notorious and life threatening. Early detection could reduce postoperative morbidity and permit safe and early discharge. This study was aimed to establish the usefulness of procalcitonin (PCT) and C-reactive protein (CRP) on postoperative day 3 as reliable markers for early detection of intra-abdominal infection and other postoperative infections following elective gastrointestinal cancer surgery. METHODS: A total of 125 patients following elective gastrointestinal cancer surgery were prospectively observed until discharge from January 2018 to December 2019. The incidence of intra-abdominal infections and other postoperative infections was recorded. Serum PCT and CRP were estimated on postoperative day 3 for all the patients. ROC analysis of PCT and CRP was performed to establish their predictability in detecting these infections. Risk factors for postoperative infections were also studied. RESULTS: The incidence of intra-abdominal infection (IAI) was 24%. The difference in PCT between the infected and non-infected patients was statistically significant (p = 0.001) but not in CRP (p = 0.223). On ROC analysis of CRP and PCT in detecting IAI, the areas under the curve were 0.494 and 0.615 respectively. CONCLUSION: Raised serum PCT values on postoperative day 3 indicate the presence of infections and should prompt the surgeon to consider other investigations to confirm the presence of IAI and other postoperative infections and plan early intervention thus expediting the postoperative recovery.

RESUMEN

Introduction: Vancomycin-resistant enterococci (VRE) are emerging as an important multidrug-resistant pathogen causing nosocomial infections, predominantly bacteremia and urinary tract infections. VRE bacteremia has caused a significant increase in the duration of the hospital stay and mortality and had caused high public health threat due to limited treatment options. Materials and methods: Between October 2017 and September 2020, all consecutive patients with culture-proven bloodstream infection with Enterococcus species, isolated for the first time, were included in the study. A total of 427 Enterococcus species were identified, and antimicrobial susceptibility tests were performed and interpreted using Clinical and Laboratory Standard Institute guidelines. Results: Of the total 427 Enterococcus species isolated, 63 (45.6%) were VRE. Among them, 51/63 (81%) were Enterococcus faecium (E. faecium) and 5/63 (8%) were Enterococcus faecalis. There was an increased trend of VRE rate in the bloodstream infections of 6.12% (2018), 13.2% (2019), and 19.2% (2020). The majority of the VRE patients [43/63 (68%)] were admitted to the intensive care units (ICUs). Vancomycin A (VanA) is the most common phenotype isolated from 51/63(81%) patients. Conclusion: This increasing trend of VRE bacteremia is a red alert to the clinicians and the infection control practitioners, so that strict antibiotic policies and proper adherence to the infection control practices can be initiated to reduce the VRE rate.

RESUMEN

Nocardia species can cause various types of infections including, pulmonary, cutaneous, disseminated & CNS diseases. Here, we report a case of disseminated nocardiosis, probably secondary to pulmonary foci, in an immunocompetent patient. Blood culture showed gram-positive bacilli, which on culture grew aerial chalky white growth showed the acid-fast, gram-positive filamentous bacteria. The culture was identified as Nocardia farcinica by MALDI-TOF. Unfortunately, the patient succumbed to the infection on the 5th day after admission.

RESUMEN

BACKGROUND: In the era of COVID-19 pandemic, there is an upsurge of healthcare-associated infections (HAI) in COVID intensive care units (ICUs), which can be reduced by following proper hand hygiene (HH) practice. Performing HH auditing in COVID ICU and providing timely feedback to the stake holders is crucial to reduce HAIs. METHODS: From November 2020- April 2021, HH audit was conducted in COVID ICUs. HH complete adherence rate (HHCAR), HH partial adherence rate (HHPAR) and HH total adherence rate (HHTAR) were analyzed. Profession-specific HHTAR and moment-specific HHTAR (for each WHO moment) were also calculated. RESULTS: HHCAR, HHPAR and HHTAR were found as 30.8%, 34.5% and 65.3% respectively. There was a significant increase in the monthly HHTAR from 26.7% to 68.4% (P < .001). The profession-specific HHAR was found to be highest among doctors (67.5%) and nurses (66.4%). As the HHTAR increases there is a significant decrease in device associated infection (DAI) rate from 24.7 to 11.5 per 1,000 device days. CONCLUSIONS: Auditing HH and providing timely feedback significantly improved HH compliance. The need of the hour is to regularly conduct HH audit in COVID locations of all healthcare facilities to reduce HAI rate among the COVID- 19 infected patients in ICUs.
