RESUMEN
BACKGROUND: Competency of the staff working in infection prevention and control (IPC) is the cornerstone of successful IPC programs. The objective was to assess competency level and associated factors among IPC staff working in the Middle East and North Africa (MENA) region. METHODS: A cross-sectional study was carried out in 2019 among active IPC staff who were members of the Arab Countries Infection Control Network. The questionnaire covered demographic and professional characteristics of IPC staff and characteristics of work facilities and IPC programs. A competency score was created from self-perceived responses to 8 competency domains. The competency score was then transformed into 100-scale and categorized into two groups (≥ median and < median). RESULTS: A total of 176 participants completed the survey. Participants were mostly female (65.7%), and the mean age was 40.2 ± 8.3 years. The mean competency score was 61.4%. It was slightly variable between domains, being highest with preventing transmission of infection (65%) and lowest with sterilization and disinfection (59%). Higher (≥ median) competency score was associated with having CBIC certification (p < 0.001). It was also associated with facilities having IPC plan (p = 0.005), IPC committee (p = 0.049), regular meetings of IPC committee (p < 0.001), and IPC plan included communications with healthcare workers (p < 0.001). Domain-specific competency scores were significantly associated with receiving same domain-specific training (p < 0.05 for all). CONCLUSIONS: The competency levels of IPC staff in the MENA region is still suboptimal. The current finding calls for more regional and national investment in IPC staff by providing up-to-date customized educational and training opportunities.

BACKGROUND: COVID-19 is the largest recorded pandemic in history. It causes several complications such as shock, pneumonia, acute respiratory distress syndrome, and organ failure. The objective was to determine COVID-19 outcomes and risk factors in the intensive care (ICU) setting. METHODS: A retrospective review of prospectively collected data was conducted. Adult patients with a positive RT-PCR test for COVID-19 admitted to ICUs of a tertiary care hospital between 2020 and 2022 were included. Patients who had severe complex trauma were excluded. The outcomes examined included ventilation use and duration, length of stay (LOS), and mortality. RESULTS: A total of 964 patients were included. The mean ( ± standard deviation, SD) age was 63.7 ± 16.9 years. The majority of the patients were males (59.0 %) and Saudi (75.7 %). Ventilation use was documented in 443 (57.1 %) patients, with a mean ( ± SD) ventilation duration of 9.7 ± 8.4 days. Death occurred in 361 (37.4 %) patients after a mean ( ± SD) of 33.3 ± 44.5 days from infection. The mean ( ± SD) LOS was 30.6 ± 54.1 days in hospital and 5.2 ± 5.4 days in ICU. Ventilation use was associated with older age, males, longer ICU LOS, mortality, and admission to medical-surgical ICU. Crude mortality use was associated with older age, longer ICU LOS, use of ventilator, shorter ventilation duration, and admission to medical-surgical or respiratory ICUs. CONCLUSIONS: COVID-19 patients admitted to adult ICUs are at high risk of death and mechanical ventilation. The crude risks of both outcomes are higher in older age and longer ICU LOS and are very variable by ICU type.

This retrospective study compared central line-associated bloodstream infection (CLABSI) rates per 1 000 central line days, and overall mortality before and during the COVID-19 pandemic in adult, paediatric, and neonatal ICU patients at King Abdul-Aziz Medical City-Riyadh who had a central line and were diagnosed with CLABSI according to the National Healthcare Safety Network standard definition. The study spanned between January 2018 and December 2019 (pre-pandemic), and January 2020 and December 2021 (pandemic). SARS-CoV-2 was confirmed by positive RT-PCR testing. The study included 156 CLABSI events and 46 406 central line days; 52 and 22 447 (respectively) in pre-pandemic, and 104 and 23 959 (respectively) during the pandemic. CLABSI rates increased by 2.02 per 1 000 central line days during the pandemic period (from 2.32 to 4.34, p < 0.001). Likewise, overall mortality rates increased by 0.86 per 1 000 patient days (from 0.93 to 1.79, p = 0.003). Both CLABSI rates (6.18 vs. 3.7, p = 0.006) and overall mortality (2.72 vs. 1.47, p = 0.014) were higher among COVID-19 patients compared to non-COVID-19 patients. The pandemic was associated with a substantial increase in CLABSI-associated morbidity and mortality.

Background: A widely-accepted standardized preventive bundle targeting multidrug-resistant organisms (MDROs) is lacking. The objective was to describe the components, implementation, compliance, and impact of a novel MDROs bundle in intensive care units (ICUs). Methods: Cohort study of surveillance activities on the components of MDROs bundle (July 2019 to June 2022) and the incidence of MDROs (April 2016 to June 2022). The implementation of MDROs bundle were preceded by ICPs-led education of the staff working in target ICUs about the importance and components of the MDROs bundle. These included the overall use of antimicrobials, appropriate environmental cleaning, appropriate contact precautions, and hand hygiene compliance. Results: During implementation, the overall use of antimicrobials was 57.8 days of therapy per 100 patient-days (44,492/76,933). It was higher in adult compared with pediatric/neonatal ICUs (p < 0.001). Appropriate environmental cleaning was 74.8% (12,409/16,582), appropriate contact precautions was 83.8% (10,467/12,497), and hand hygiene compliance was 86.9% (27,023/31,096). The three components were significantly higher in pediatric/neonatal compared with adult ICUs (p = 0.027, p < 0.001, p = 0.006, respectively). The MDROs rates per 10,000 patient-days were 71.8 before (April 2016 to June 2019) and 62.0 during (July 2019 to June 2022) the bundle implementation (858/119,565 versus 891/143,649 p = 0.002). The reduction in MDROs rates were replicated in adult (p = 0.001) but not pediatric/neonatal ICUs (p = 0.530). Conclusions: The finding of this study indicate that the implementation of the current bundle was associated with a modest decrease in MDROs rates in adult ICUs. The provided detailed definitions and methodology will facilitate its use by other healthcare facilities.
RESUMEN
BACKGROUND: The general human immune responses similarity against different coronaviruses may reflect some degree of cross-immunity, whereby exposure to one coronavirus may confer partial immunity to another. The aim was to determine whether previous MERS-CoV infection was associated with a lower risk of subsequent COVID-19 disease and its related outcomes. METHODS: We conducted a retrospective cohort study among all patients screened for MERS-CoV at a tertiary care hospital in Saudi Arabia between 2012 and early 2020. Both MERS-CoV positive and negative patients were followed up from early 2020 to September 2021 for developing COVID-19 infection confirmed by RT-PCR testing. RESULTS: A total of 397 participants followed for an average 15 months during COVID-19 pandemic (4.9 years from MERS-CoV infection). Of the 397 participants, 93 (23.4%) were positive for MERS-CoV at baseline; 61 (65.6%) of the positive cases were symptomatic. Out of 397, 48 (12.1%) participants developed COVID-19 by the end of the follow-up period. Cox regression analysis adjusted for age, gender, and major comorbidity showed a marginally significant lower risk of COVID-19 disease (hazard ratio = 0.533, p = 0.085) and hospital admission (hazard ratio = 0.411, p = 0.061) in patients with positive MERS-CoV. Additionally, the risk of COVID-19 disease was further reduced and became significant in patients with symptomatic MERS-CoV infection (hazard ratio = 0.324, p = 0.034) and hospital admission (hazard ratio = 0.317, p = 0.042). CONCLUSIONS: The current findings may indicate a partial cross-immunity, where patients with symptomatic MERS-CoV have a lower risk of future COVID-19 infection and related hospitalization. The present results may need further examination nationally using immunity markers.

Background: Portable computerized devices represent a potential source of healthcare infections. The objective was to assess the knowledge, attitudes, and practices (KAP) of healthcare workers (HCWs) toward infection control practices used with Close Loop Medication Administration (CLMA) devices. Additionally, to quantify the impact of education and training on the bacterial burden on CLMA devices. Methods: The study design consisted of two steps: a cross-sectional study was conducted among HCWs working in a tertiary care center in Riyadh, Saudi Arabia. A 32-item questionnaire was used to assess KAP information. The second step was environmental samples collected from the surfaces of CLMA devices before and after implementing a multifaceted intervention. Result: A total of 325 HCWs were included in the study. The mean age was 32.6±7.4 years. The majority were females (92%) and nurses (91.3%). The overall KAP score was 74.8%, 74.2% adequate knowledge, 79.3% positive attitude, and 71.3% appropriate practices. KAP score was better (≥ median KAP score) among HCWs working in laboratory and organ transplant units (P<0.001). It was also better among those with a longer duration of work experience (P<0.001) and those who received related training (P<0.001). Approximately 75% of HCWs expressed their need for more information about CLMA. Post-interventional samples had much lower bacterial burden, with the positive rate reduced from 51.4% before intervention to 16.8% after intervention (P<0.001). Conclusions: Awareness and behavior of HCWs about appropriate infection control practices related to portable devices is still inadequate. A multifaceted intervention including education and training significantly reduces the bioburden on portable devices.
RESUMEN
BACKGROUND: Surveillance data are very essential for the effective use of available resources, the prioritization of infection control practices, and setting goals for intervention. The aim was to present the current rates of healthcare-associated infections (HAIs) and device utilization ratios (DUR) among the Saudi Ministry of health (MOH) hospitals. METHODS: MOH analyzed the surveillance data collected from 106 MOH hospitals enrolled in the health electronic surveillance network (HESN) between January 2022 and December 2022. The surveillance methodology was similar to the methods of the US National Healthcare Safety Network (NHSN) and the Gulf Cooperation Council (GCC) center for infection control. RESULTS: More than one million device-days of surveillance were analyzed. The rate of central line associated bloodstream infection (CLABSI) was 2.57 per 1000 central lines days. The rate of catheter-associated urinary tract infection (CAUTI) was 1.08 per 1000 urinary catheter days. The rate of ventilator-associated events (VAE) was 4.21 per 1000 ventilator days. The average rate of pediatric/neonatal ventilator-associated pneumonia (VAP) was 1.53 per 1000 ventilator days. The average DURs were 0.33 for central line, 0.61 for urinary catheter, 0.44 for ventilator in adult patients, and 0.26 in ventilator in pediatric/neonatal patients. In 238632 months of surveillance, the rate of dialysis events (DE) was 0.97 per 100 patient-months. In 86324 surgeries monitored, the rate of surgical site infection (SSI) was 0.87 per 100 surgeries surveyed. CONCLUSIONS: The current report can serve as a national benchmark for MOH hospitals and a regional benchmark for similar hospitals in the region.
RESUMEN
BACKGROUND: COVID-19 is believed to increase the risk of secondary health care...associated infections. The objective was to estimate the impact of COVID-l9 pandemic on the rates of central line...associated bloodstream infection (CLABSI) and catheter-associated urinary tract infections (CAUTIs) in the.ßMinistry of Health hospitals across Saudi Arabia. METHODS: A retrospective analysis of prospectively collected CLABSI and CAUTI data over a period of 3 years (2019-2021) was done. The data were obtained from the Saudi Health Electronic Surveillance Network. All adult intensive care units in 78 Ministry of Health hospitals that contributed CLABSI or CAUTI data before (2019) and during (2020-2021).ßthe pandemic were included. RESULTS: During the study, 1440 CLABSI events and 1119 CAUTI events were identified. CLABSI rates significantly increased in 2020-2021 compared with 2019 (2.50 versus 2.16 per 1000 central line days, P.ß=.ß.010). CAUTI rates significantly decreased in 2020-2021 compared with 2019 (0.96 versus 1.54 per 1000 urinary catheter days, P.ß<.ß.001). CONCLUSIONS: COVID-19 pandemic is.ßassociated with increased CLABSI rates and reduced CAUTI rates. It.ßis believed to have negative impacts on several infection control practices and surveillance accuracy. The opposite impacts of COVID-19 on CLABSI and CAUTI probably reflect.ßthe nature of their case definitions.

BACKGROUND: Surveillance of healthcare-associated infections (HAIs) is a cornerstone for effective infection prevention and control (IPC) programs. The objective was to evaluate the coverage and methods of HAI surveillance in Middle Eastern and North African (MENA) countries. METHODS: A cross-sectional study targeted IPC staff working in MENA countries using the Infection Control Network electronic database of the Arab countries. The study focused on self-reported surveillance-related characteristics of IPC staff, facilities, and the IPC program. RESULTS: A total of 269 IPC staff were included. They were mainly females (68%), nurses (63%), and working in GCC countries (83%). Approximately 69% of covered facilities had surveillance activities. Hand hygiene, multidrug-resistant organisms, central line-associated bloodstream infections, and catheter-associated urinary tract infections were the most common surveillance activities (>90%). The surveillance workload consumed 27% of the average weekly working time. The scores of performing multiple surveillance, with appropriate methods and tools, were 83%, 67%, and 61% (respectively). Appropriate surveillance methods and/or tools were linked to GCC region, CBIC qualifications, surveillance training, specific setting (acute care and long term), staff-to-bed ratio, presence and active function of IPC committee, presence of IPC annual plan, communications with health care workers, and leadership support. CONCLUSIONS: While most health care facilities in the MENA region perform multiple surveillance, surveillance methods and tools are still suboptimal and their optimization should be a priority.

OBJECTIVE: To examine the distribution and the trend of airborne particles and bio-aerosol concentration in pediatric intensive care units (PICUs) in two tertiary care hospitals with different ventilation setting. METHODS: Hospitals A but not B is provided with a central HEPA filter. PICUs in both hospitals were categorized into protective environment (PE) with room HEPA filter, semi-protective environment (SPE) with portable air-purifier, and non-protective environment (NPE) with neither system. Fine particles (≤ 2.5 µm) and coarse particles (≤ 10.0 µm) were obtained using optical particle counter (Lighthouse Handheld 3016) and total bacterial (TBC) and fungal (TFC) counts were obtained using Andersen air sampler. RESULTS: Hospital B had significantly higher levels of fine and coarse particles (in all room), TBC (in PE), but not TFC compared with matched rooms in hospital A. In hospital B, the levels of fine particles, coarse particles, and TBC were lowest in SPE (p < 0.001, p = 0.004, and p = 0.006, respectively) while TFC was lowest in NPE (p = 0.014). Airborne particles, TBC, and TFC had variable trends with some of the indoor peaks follow outdoor peaks. Gram-positive bacteria (69 %) were the predominant bacteria in hospital A while bacterial flora (70 %) were the predominant bacteria in hospital B (p < 0.001 for each). CONCLUSIONS: The levels of airborne contaminants and microbial counts in PICUs are significantly affected by the ventilation system and to less extent by outdoor levels. The results indicated that advanced filtration system and central HEPA filters play a significant role in the reduction of indoor fine particulates and TBC.

The outcome of transplant recipients is variable depending on the study population, vaccination status and COVID-19 variants. Our aim was to study the impact of Omicron subvariants on the mortality of transplant recipients. We reviewed the results of SARS-CoV-2 whole genome sequence of random isolates collected from 29 December 2021 until 17 May 2022 in King Faisal Specialist Hospital and Research center, Jeddah (KFSHRC-J), Saudi Arabia performed as hospital genomic surveillance program for COVID-19 variants. We included 25 transplant patients infected with confirmed Omicron variants.17 (68%) and 8 (32%) patients had Omicron BA.1 and BA.2, respectively. 12 (68%) patients had renal transplants. Only 36% of patients received three doses of COVID-19 vaccines. 23 (92%) patients required hospitalization. 20 (80%) patients survived and 6 (25%) required intensive care unit (ICU) admission. Among ICU patients, 66.7% were more than 50 years, 50% had two to three comorbidities and 5 out of 6 (83%) died. The mortality of transplant patients infected with Omicron variants in our cohort was higher than other centers as a limited number of patients received booster vaccines. Optimizing booster vaccination is the most efficient method to improve the mortality of COVID-19 in transplant recipients recognizing the inefficacy of monoclonal antibodies in the presence of SARS-CoV-2 emerging variants. We did not show a difference in mortality in transplant patients infected with Omicron BA.1 and BA.2 knowing the limitation of our sample size.

BACKGROUND: Nosocomial outbreaks frequently occurred during the Coronavirus disease 2019 (COVID-19) pandemic; however, sharing experiences on outbreak containment is vital to reduce the related burden in different locations. OBJECTIVES: This article aims at sharing a practical experience on COVID-19 outbreak containment, including contact tracing, screening of target population, testing including molecular analysis, and preventive modalities. It also provides an epidemiological and molecular analysis of the Severe Acute Respiratory Syndrome Coronavirus 2 (SARSCoV2) infection outbreak in a tertiary care hospital in Saudi Arabia. METHODS: The outbreak occurred in a non-COVID medical ward at a tertiary care hospital in Jeddah, Saudi Arabia, from 22nd March and 15th April 2021. The multidisciplinary outbreak response team performed clinical and epidemiological investigations. Whole-Genome Sequencing (WGS) was implemented on selected isolates for further molecular characterization. RESULTS: A total of eight nurses (20 % of the assigned ward nurses) and six patients (16.2 % of the ward admitted patients at the time of the outbreak) tested positive for the SARS-CoV-2 virus based on PCR testing. The outbreak investigation identified strong evidence of an epidemiologic link between the affected cases. WGS revealed a set of spike mutations and deletions specific to the Alpha variant (B.1.1.7 lineage). All the nurses had mild symptoms, and the fatality among the patients was 50 % (three out of the six patients). CONCLUSIONS: The current nosocomial COVID-19 outbreak, caused by the Alpha variant, revealed multiple breaches in the adherence to the hospital infection control recommended measures. Containment strategies were successful in controlling the outbreak and limiting infection spread. Molecular analysis and genome sequencing are essential tools besides epidemiological investigation to inform appropriate actions, especially with emerging pathogens.

BACKGROUND: COVID-19 de-isolation guidelines of health care workers (HCW) were formulated based on evidence describing the duration of infectious viral shedding of the wild SARS-CoV-2 virus. During the periods of COVID-19 vaccination and variants, a test-based approach was recommended to end isolation of HCW, based on emerging data describing the viral kinetics of COVID-19 variants. While Rapid antigen detection tests (RADT) are increasingly used in the diagnosis of COVID-19, their use is limited in de-isolation. METHODS: We described the use of RADT in the de-isolation of COVID-19 vaccinated HCW with mild infection who were asymptomatic on day 7 post diagnosis in a single center retrospective cohort study during the Omicron surge. RESULTS: Of the 480 HCWs, 173 (36%) had positive RADT. The positivity rate of RADT was not different in HCW who received two doses versus three doses of vaccine (34.4% versus 40.3%, p = 0.239). CONCLUSIONS: A symptom based, test-based approach using RADT is a useful tool in the de-isolation of HCW, with mild disease, in the era of Omicron. Further studies are required to evaluate the role of RADT in de-isolation of patients with severe COVID-19 disease.

INTRODUCTION: Infection prevention and control (IPC) programs in the Middle Eastern and North African (MENA) countries are evolving. The objective was to characterize IPC personnel and programs in MENA countries, with special emphasis on the differences between Gulf Cooperation Council (GCC) and non-GCC countries. METHODOLOGY: A cross-sectional online survey was conducted in 2019 among IPC members of the Arab Countries Infection Control Network (AcicN). The survey focused on three domains; demographic and professional characteristics, organizational structure, and IPC program characteristics. RESULTS: A total of 269 participants aged 39.9 ± 8.4 years were included in the study. Majority of the participants were females (67.7%), nurses (63.7%), and of Middle-Eastern origin (57.3%). 32.2% of the participants were certified by the Certification Board of Infection Control (CBIC). Only 22.7% of participants were satisfied with their current compensation. Surveillance was the most time-consuming task (26.6%), followed by isolation (12.4%), and investigation of outbreaks (12.1%). Majority of the facilities had at least one IPC personnel per 100 beds (60.9%), supported IPC program (63.9%), a formal IPC committee (93.7%), and an IPC plan (91.4%). Compared with non-GCC countries, GCC countries had significantly more frequent CBIC certification (p = 0.003), training in cleaning/sterilization (p = 0.010), supported IPC program (p = 0.010), formal IPC committee (p = 0.001), IPC plan (p = 0.001), and higher number of IPC personnel per 100 beds (p = 0.047). CONCLUSIONS: MENA countries had generally satisfactory IPC programs and to a lesser extent staffing, with considerable variability between countries with different resources.

BACKGROUND: Data examining differences in antimicrobial therapy and its appropriateness between healthcare-associated infections (HAIs) and community-associated infections (CAIs) are limited. The objective was to compare antimicrobial therapy, resistance, and appropriateness between CAIs and HAIs. METHODS: One-day point prevalence survey targeting admitted patients with active infections was conducted in six tertiary care hospitals. Antimicrobial appropriateness was decided based on hospital antimicrobial guidelines, clinical assessment, culture results, and other relevant investigations. RESULTS: Out of 1666 patient records reviewed, 240 (14.4%) infection events were identified. Prevalence of infections treated with antimicrobials were 6.5% for HAIs and 7.1% for CAIs. The most commonly prescribed antimicrobials were carbapenems (19.6%), cephalosporins (14.8%), and vancomycin (13.2%), with some differences between HAIs and CAIs. The overall contribution of MDR pathogens to both HAIs and CAIs was similar (34.0% versus 34.3%, p = 0.969). ESBL was significantly associated with CAIs while other gram-negative MDR pathogens significantly associated with HAIs. Overall appropriateness of antimicrobial therapy was similar in HAI and CAI events (64.2% versus 64.7%, p = 0.934). However, it was highest in aminoglycosides (78.6%) and lowest in vancomycin (40.8%). It was lowest in bloodstream infections than other infections (48.5% versus 61% to 78%, p = 0.044). CONCLUSION: Although the overall burden of MDR pathogens and appropriateness of antimicrobial therapy were similar in HAI and CAI events, there were some differences related to the type of MDR, type of antimicrobials, and type of infection. The current finding can guide training and educational activities of local antimicrobial stewardship initiatives aiming to improve antimicrobial therapy in hospital setting.

BACKGROUND: Rheumatic diseases patients receiving Rituximab had severe COVID-19 disease. Although they had impaired humoral immune responses following COVID-19 vaccine, they had preserved cellular immune responses. Waning of COVID-19 antibody responses was observed within six months post vaccination among immunocompromised patients. Recent reports showed fatal outcome of breakthrough SARS-CoV-2 infections among vaccinated high-risk rheumatic diseases patients receiving Rituximab. SAR-CoV-2 serological tests were not performed. OBJECTIVE: Evaluation of COVID-19 vaccine humoral responses and breakthrough infections among low risk fully vaccinated rheumatic patients during the Delta Variant Era. METHODS: A case series of 19 fully vaccinated patients with rheumatic diseases were followed to determine post vaccine SARS-CoV-2 neutralizing antibody titers and to monitor the development of breakthrough infections up to eight months post vaccine at our tertiary care center in Jeddah, Saudi Arabia from 1st April until 30th November 2021. RESULTS: The mean age of patients was 49 years old. 10% of patients were receiving Rituximab. 73% of patients had positive SARS-CoV-2 serological testing post second vaccine. Two mild breakthrough COVID-19 infections were diagnosed six months post second dose of vaccine. Patients were less than 65 years, did not receive Rituximab, did not have interstitial lung diseases and had positive post vaccine serological testing. CONCLUSIONS: We demonstrated high SARS-CoV-2 neutralizing antibodies seroprevalence and self-limiting breakthrough infections in low risk rheumatic diseases patients during the Delta Era. Future studies are needed to study the outcome of rheumatic diseases patients in the Era of Omicron in view of viral immune escape responses.

BACKGROUND: The higher risk of COVID-19 in health care workers (HCWs) is well-known. However, the risk within HCWs is not fully understood. The objective was to compare the COVID-19 risk in intensive care unit (ICU) vs non-ICU locations. METHODS: A prospective surveillance study was conducted among HCWs at a large tertiary care facility in Riyadh between March 1st to November 30th, 2020. HCWs included both clinical (provide direct patient care) and nonclinical positions (do not provide direct patient care). RESULTS: A total 1,594 HCWs with COVID-19 were included; 103 (6.5%) working in ICU and 1,491 (93.5%) working in non-ICU locations. Compared with non-ICU locations, ICU had more nurses (54.4% vs 22.1%, P < .001) and less support staff (2.9% vs 53.1%, P < .001). COVID-19 infection was similar in ICU and non-ICU locations (9.0% vs 9.8%, P = .374). However, it was significantly higher in ICU nurses (12.3% vs 6.5%, P < .001). Support staff had higher risk than other HCWs, irrespective of ICU working status (15.1% vs 7.2%, P < 0.001). The crude relative risk of COVID-19 in ICU vs non-ICU locations was 0.92, 95% confidence interval ( was 0.76-1.11 (P = .374). However, relative risk adjusted for professional category was significantly increased to 1.23, 95% confidence interval 1.01-1.50 (P = .036). CONCLUSIONS: ICU had a significantly higher risk of COVID-19 infection only after adjusting for the distribution and risk of different professional categories. The latter is probably determined by both exposure level and protection practices. The finding underscores the importance of strict implementation of preventive measures among all HCWs, including those performing nonclinical services.

Healthcare workers have been categorized among the priority groups for COVID-19 vaccination. However, post-vaccination infections have been identified. This study was conducted to investigate SARS-CoV-2 infection among healthcare workers (HCWs) who received the COVID-19 vaccine. A case series in a multicenter healthcare system in Saudi Arabia was created from HCWs who had (PCR-RT) confirmed SARS-CoV-2 infection after at least one dose of Pfizer-BioNTech vaccination. A total of 20 healthcare workers (HCWs) have been included. The majority (70.0%) were males and the average age was 39.4 ± 10.1 years. They included physicians (55.0%), nurses (25.0%) and other HCWs (20.0%). Eighteen (90%) HCWs had infection after the first dose; 47.1% within the first week, 41.2% within the second week, and 11.8% within the third week. Only two HCWs (10.0%) had infection one week after the second dose. The majority (63.2%) had mild (52.6%) or moderate (10.3%) disease with no severe disease or hospitalization. The majority of post-vaccination COVID-19 infections among HCWs occurred before the full protection of the vaccine is gained. Suspicion of COVID-19 infection should be considered even with a history of COVID-19 vaccination. Recently vaccinated HCWs should be advised to fully comply with all recommended precautions to prevent COVID-19 transmission.

OBJECTIVES: The COVID-19 pandemic has had a substantial impact on health systems. The WHO Antimicrobial Resistance (AMR) Surveillance and Quality Assessment Collaborating Centres Network conducted a survey to assess the effects of COVID-19 on AMR surveillance, prevention and control. METHODS: From October to December 2020, WHO Global Antimicrobial Resistance and Use Surveillance System (GLASS) national focal points completed a questionnaire, including Likert scales and open-ended questions. Data were descriptively analysed, income/regional differences were assessed and free-text questions were thematically analysed. RESULTS: Seventy-three countries across income levels participated. During the COVID-19 pandemic, 67% reported limited ability to work with AMR partnerships; decreases in funding were frequently reported by low- and middle-income countries (LMICs; P < 0.01). Reduced availability of nursing, medical and public health staff for AMR was reported by 71%, 69% and 64%, respectively, whereas 67% reported stable cleaning staff availability. The majority (58%) reported reduced reagents/consumables, particularly LMICs (P < 0.01). Decreased numbers of cultures, elective procedures, chronically ill admissions and outpatients and increased ICU admissions reported could bias AMR data. Reported overall infection prevention and control (IPC) improvement could decrease AMR rates, whereas increases in selected inappropriate IPC practices and antimicrobial prescribing could increase rates. Most did not yet have complete data on changing AMR rates due to COVID-19. CONCLUSIONS: This was the first survey to explore the global impact of COVID-19 on AMR among GLASS countries. Responses highlight important actions to help ensure that AMR remains a global health priority, including engaging with GLASS to facilitate reliable AMR surveillance data, seizing the opportunity to develop more sustainable IPC programmes, promoting integrated antibiotic stewardship guidance, leveraging increased laboratory capabilities and other system-strengthening efforts.
