Incidence, Clinical Characteristics, and Outcomes of Clostridium difficile Infection in a Tertiary Care Center in Bahrain.

Background Clostridioides difficile infection (CDI) represents a significant healthcare challenge associated with antibiotic use and healthcare settings. While healthcare facility-onset CDI (HO-CDI) rates have been extensively studied, the incidence and risk factors of CDI in various settings, including the community, require further investigation. Aim This study aims to examine the incidence rates of CDI in a major governmental hospital in Bahrain, identify risk factors for CDI, and assess the effectiveness of infection control measures. Method We conducted a retrospective study at the Salmaniya Medical Complex (SMC), analyzing all confirmed cases of CDI over a 30-month period from January 2021 to June 2023. CDI cases were screened using glutamine dehydrogenase antigen detection and confirmed using molecular assays like polymerase chain reaction and/or toxin assays for confirmation. The study categorized CDI cases based on their onset (hospital or community) and explored associated risk factors, including antibiotic use, proton pump inhibitor (PPI) therapy, and patient demographics. Infection control practices were also evaluated for their role in managing CDI. Results About 57 new CDI cases were identified during the study period, with a HO-CDI incidence rate of 0.5 per 10,000 patient days. While HO-CDI rates remained stable, community-onset (CO)-CDI cases increased. The median patient age was 61.8 years, without notable differences between genders. Key risk factors for CDI were antimicrobial therapy, use of acid-reducing agents, age, and underlying comorbidities. The mortality rate stood at 35.1%. The ATLAS score (i.e., age, treatment with antibiotics, leukocyte count, albumin level, and serum creatinine) was a reliable predictor of mortality. Critical care admission and low albumin levels emerged as significant independent risk factors for mortality. Conclusions The study demonstrates a low incidence rate of HO-CDI at SMC, attributed to effective infection control and antibiotic stewardship programs. The overall CDI rate increased during the study period, driven by a rise in CO cases; further investigating the risk factors among this category in our study revealed that most patients were exposed to antibiotic therapy within the past three months of their CDI diagnosis. The rise in CO-CDI cases underscores the need for broader community-based interventions and awareness regarding antibiotic and PPI use.

Evaluation of an adjusted MEWS (Modified Early Warning Score) for COVID-19 patients to identify risk of ICU admission or death in the Kingdom of Bahrain.

BACKGROUND: While most COVID-19 cases have uncomplicated infection, a small proportion has the potential to develop life-threatening disease, as such development of a prediction tool using patients baseline characteristics at the time of diagnosis should aid in early identification of high-risk groups and devise pertinent management. Hence, we set up this retrospective study to determine preadmission triaging tool to predict the development of severe COVID-19 in the Kingdom of Bahrain MATERIALS AND METHODS: A retrospective study was conducted from 1 September 2020 to 30 November 2020 with enrolment of all SARS-CoV-2 PCR-confirmed persons aged ≥ 14 years who attended Al-Shamil Field Hospital (SFH) in the Kingdom of Bahrain for triaging and assessment with recording of the following parameters: systolic blood pressure, heart rate, respiratory rate, temperature, the alert, verbal, pain, unresponsive neurological score, age, oxygen saturation, comorbidities, Body Mass Index (BMI), duration of symptoms and living with immunocompromised populations to develop our local adjusted MEWS as predictor for ICU admission & for consideration of suitable isolation at home. Follow up data of all patients was obtained from the electronic medical records system including CXR findings, treatments/medications received, need of oxygen supplements /intubation, needs of ICU care, and the outcome (death /discharged alive) IBM SPSS statistic version 21 program was used for data analysis. RESULTS: Our study showed that using the locally developed adjusted MEWS score, there was an significant association between high value of this adjusted MEWS score and abnormal radiographic finding (49.7 % Vs. 17 % for patients with high score Vs. those with low score respectively). Out of the 181 patients with high scores on adjusted MEWS; 38.7 % required oxygen via nasal cannula, 14.4 % required face mask and 8.3 % non-rebreather mask; this proportion was significantly higher than their counterpart patients who score low on adjusted MEWS (20.9 %, 7.7 %, 4.8 %respectively) with statistically significance difference between the two groups (p value of 0.00, 0.00,.004 respectively) Requirement of ICU admission was significantly higher among patients with high score in comparison to those with low score (14.4 % vs. 3 %) with significant p value (0.00) But higher score value was not associated significantly with increase mortality rate among COVID patients. CONCLUSION: Development of our new Adjusted MEWS score system by adding the additional elements of age, oxygen saturation, comorbidities, Body Mass Index (BMI) and duration of symptoms found to be very useful predictor tool for preadmission triaging of COVID patients based on their risk assessment to help clinician to decide on the appropriate placement to different level of isolation facilities.

Hand Hygiene Knowledge and Perception Survey for Healthcare Workers in Government Hospitals (GHs) in Bahrain.

Introduction and aim Healthcare-associated infections (HAIs) are a serious concern in all healthcare facilities as they may lead to many serious consequences, like prolonged hospitalization, increased mortality and morbidity, and extra costs. Effective hand hygiene (HH) is the primary proven measure known to be effective in reducing the risk of HAIs in all healthcare settings. This study aimed to measure the healthcare workers' (HCWs) knowledge and perception of HH at government hospitals (GHs) in Bahrain. Subjects and methods This cross-sectional study was conducted among HCWs working in GHs in the Kingdom of Bahrain. A self-administered questionnaire was distributed among the targeted population using a Google survey (Google LLC, California, USA). The questionnaire includes socio-demographic data (e.g., age, gender, nationality, etc.) and a validated WHO questionnaire measuring perceptions and knowledge toward HH. Results Of the 285 HCWs, 75.4% were females, and 48.1% were aged between 31 and 40 years old. The overall mean perception was 35.9 (SD 6.93) out of 42 points, with nearly 80% of HCWs considered to have good perception levels. The overall mean knowledge score was 11.4 (SD 1.37) out of 14 points. Accordingly, 75.4% were considered to have good knowledge levels. Factors associated with increased perception include increasing age, female gender, non-Bahraini, being a nurse with increasing years of working experience, and receiving formal training in HH. Being a nurse was the sole significant predictor of increased knowledge. Conclusion The knowledge and perception of HH among HCWs were sufficient. Being a nurse was a significant predictor of both knowledge and perception. Further, a significant positive correlation was noted between the knowledge and perception scores. Maintaining the level of knowledge and perception of HH could lead to improved HH compliance among HCWs.

Six-year multicenter study on short-term peripheral venous catheters-related bloodstream infection rates in 246 intensive units of 83 hospitals in 52 cities of 14 countries of Middle East: Bahrain, Egypt, Iran, Jordan, Kingdom of Saudi Arabia, Kuwait, Lebanon, Morocco, Pakistan, Palestine, Sudan, Tunisia, Turkey, and United Arab Emirates-International Nosocomial Infection Control Consortium (INICC) findings.

BACKGROUND: Short-term peripheral venous catheters-related bloodstream infections (PVCR-BSIs) rates have not been systematically studied, and data on their incidence by number of device-days is not available. METHODS: Prospective, surveillance study on PVCR-BSI conducted from September 1st, 2013 to 31st Mays, 2019 in 246 intensive care units (ICUs), members of the International Nosocomial Infection Control Consortium (INICC), from 83 hospitals in 52 cities of 14 countries in the Middle East (Bahrain, Egypt, Iran, Jordan, Kingdom of Saudi Arabia, Kuwait, Lebanon, Morocco, Pakistan, Palestine, Sudan, Tunisia, Turkey, and United Arab Emirates). We applied U.S. RESULTS: We followed 31,083 ICU patients for 189,834 bed-days and 202,375 short term peripheral venous catheter (PVC)-days. We identified 470 PVCR-BSIs, amounting to a rate of 2.32/1000 PVC-days. Mortality in patients with PVC but without PVCR-BSI was 10.38%, and 29.36% in patients with PVC and PVCR-BSI. The mean length of stay in patients with PVC but without PVCR-BSI was 5.94 days, and 16.84 days in patients with PVC and PVCR-BSI. The microorganism profile showed 55.2 % of gram-positive bacteria, with Coagulase-negative Staphylococci (31%) and Staphylococcus aureus (14%) being the predominant ones. Gram-negative bacteria accounted for 39% of cases, and included: Escherichia coli (7%), Klebsiella pneumoniae (8%), Pseudomonas aeruginosa (5%), Enterobacter spp. (3%), and others (29.9%), such as Serratia marcescens. CONCLUSIONS: PVCR-BSI rates found in our ICUs were much higher than rates published from USA, Australia, and Italy. Infection prevention programs must be implemented to reduce the incidence of PVCR-BSIs.

Six-year multicenter study on short-term peripheral venous catheters-related bloodstream infection rates in 727 intensive care units of 268 hospitals in 141 cities of 42 countries of Africa, the Americas, Eastern Mediterranean, Europe, South East Asia, and Western Pacific Regions: International Nosocomial Infection Control Consortium (INICC) findings.

BACKGROUND: Short-term peripheral venous catheter-related bloodstream infection (PVCR-BSI) rates have not been systematically studied in resource-limited countries, and data on their incidence by number of device days are not available. METHODS: Prospective, surveillance study on PVCR-BSI conducted from September 1, 2013, to May 31, 2019, in 727 intensive care units (ICUs), by members of the International Nosocomial Infection Control Consortium (INICC), from 268 hospitals in 141 cities of 42 countries of Africa, the Americas, Eastern Mediterranean, Europe, South East Asia, and Western Pacific regions. For this research, we applied definition and criteria of the CDC NHSN, methodology of the INICC, and software named INICC Surveillance Online System. RESULTS: We followed 149,609 ICU patients for 731,135 bed days and 743,508 short-term peripheral venous catheter (PVC) days. We identified 1,789 PVCR-BSIs for an overall rate of 2.41 per 1,000 PVC days. Mortality in patients with PVC but without PVCR-BSI was 6.67%, and mortality was 18% in patients with PVC and PVCR-BSI. The length of stay of patients with PVC but without PVCR-BSI was 4.83 days, and the length of stay was 9.85 days in patients with PVC and PVCR-BSI. Among these infections, the microorganism profile showed 58% gram-negative bacteria: Escherichia coli (16%), Klebsiella spp (11%), Pseudomonas aeruginosa (6%), Enterobacter spp (4%), and others (20%) including Serratia marcescens. Staphylococcus aureus were the predominant gram-positive bacteria (12%). CONCLUSIONS: PVCR-BSI rates in INICC ICUs were much higher than rates published from industrialized countries. Infection prevention programs must be implemented to reduce the incidence of PVCR-BSIs in resource-limited countries.

International Nosocomial Infection Control Consortium (INICC) report, data summary of 45 countries for 2012-2017: Device-associated module.

BACKGROUND: We report the results of International Nosocomial Infection Control Consortium (INICC) surveillance study from January 2012 to December 2017 in 523 intensive care units (ICUs) in 45 countries from Latin America, Europe, Eastern Mediterranean, Southeast Asia, and Western Pacific. METHODS: During the 6-year study period, prospective data from 532,483 ICU patients hospitalized in 242 hospitals, for an aggregate of 2,197,304 patient days, were collected through the INICC Surveillance Online System (ISOS). The Centers for Disease Control and Prevention-National Healthcare Safety Network (CDC-NHSN) definitions for device-associated health care-associated infection (DA-HAI) were applied. RESULTS: Although device use in INICC ICUs was similar to that reported from CDC-NHSN ICUs, DA-HAI rates were higher in the INICC ICUs: in the medical-surgical ICUs, the pooled central line-associated bloodstream infection rate was higher (5.05 vs 0.8 per 1,000 central line-days); the ventilator-associated pneumonia rate was also higher (14.1 vs 0.9 per 1,000 ventilator-days,), as well as the rate of catheter-associated urinary tract infection (5.1 vs 1.7 per 1,000 catheter-days). From blood cultures samples, frequencies of resistance, such as of Pseudomonas aeruginosa to piperacillin-tazobactam (33.0% vs 18.3%), were also higher. CONCLUSIONS: Despite a significant trend toward the reduction in INICC ICUs, DA-HAI rates are still much higher compared with CDC-NHSN's ICUs representing the developed world. It is INICC's main goal to provide basic and cost-effective resources, through the INICC Surveillance Online System to tackle the burden of DA-HAIs effectively.

International Nosocomial Infection Control Consortium report, data summary of 50 countries for 2010-2015: Device-associated module.

BACKGROUND: We report the results of International Nosocomial Infection Control Consortium (INICC) surveillance study from January 2010-December 2015 in 703 intensive care units (ICUs) in Latin America, Europe, Eastern Mediterranean, Southeast Asia, and Western Pacific. METHODS: During the 6-year study period, using Centers for Disease Control and Prevention National Healthcare Safety Network (CDC-NHSN) definitions for device-associated health care-associated infection (DA-HAI), we collected prospective data from 861,284 patients hospitalized in INICC hospital ICUs for an aggregate of 3,506,562 days. RESULTS: Although device use in INICC ICUs was similar to that reported from CDC-NHSN ICUs, DA-HAI rates were higher in the INICC ICUs: in the INICC medical-surgical ICUs, the pooled rate of central line-associated bloodstream infection, 4.1 per 1,000 central line-days, was nearly 5-fold higher than the 0.8 per 1,000 central line-days reported from comparable US ICUs, the overall rate of ventilator-associated pneumonia was also higher, 13.1 versus 0.9 per 1,000 ventilator-days, as was the rate of catheter-associated urinary tract infection, 5.07 versus 1.7 per 1,000 catheter-days. From blood cultures samples, frequencies of resistance of Pseudomonas isolates to amikacin (29.87% vs 10%) and to imipenem (44.3% vs 26.1%), and of Klebsiella pneumoniae isolates to ceftazidime (73.2% vs 28.8%) and to imipenem (43.27% vs 12.8%) were also higher in the INICC ICUs compared with CDC-NHSN ICUs. CONCLUSIONS: Although DA-HAIs in INICC ICU patients continue to be higher than the rates reported in CDC-NSHN ICUs representing the developed world, we have observed a significant trend toward the reduction of DA-HAI rates in INICC ICUs as shown in each international report. It is INICC's main goal to continue facilitating education, training, and basic and cost-effective tools and resources, such as standardized forms and an online platform, to tackle this problem effectively and systematically.
