Gholipour S, Nikaeen M, Mohammadi F, Rabbani D. Antibiotic resistance pattern of waterborne causative agents of healthcare-associated infections: A call for biofilm control in hospital water systems. J Infect Public Health 2024; 17:102469. [PMID: 38838607 DOI: 10.1016/j.jiph.2024.102469] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/05/2024] [Revised: 05/27/2024] [Accepted: 05/28/2024] [Indexed: 06/07/2024] Open
Abstract
BACKGROUND In recent years, the global spread of antimicrobial resistance has become a concerning issue, often referred to as a "silent pandemic". Healthcare-associated infections (HAIs) caused by antibiotic-resistant bacteria (ARB) are a recurring problem, with some originating from waterborne route. The study aimed to investigate the presence of clinically relevant opportunistic bacteria and antibiotic resistance genes (ARGs) in hospital water distribution systems (WDSs). METHODS Water and biofilm samples (n = 192) were collected from nine hospitals in Isfahan and Kashan, located in central Iran, between May 2022 and June 2023. The samples were analyzed to determine the presence and quantities of opportunistic bacteria and ARGs using cultural and molecular methods. RESULTS Staphylococcus spp. were highly detected in WDS samples (90 isolates), with 33 % of them harboring mecA gene. However, the occurrences of E. coli (1 isolate), Acinetobacter baumannii (3 isolates), and Pseudomonas aeruginosa (14 isolates) were low. Moreover, several Gram-negative bacteria containing ARGs were identified in the samples, mainly belonging to Stenotrophomonas, Sphingomonas and Brevundimonas genera. Various ARGs, as well as intI1, were found in hospital WDSs (ranging from 14 % to 60 %), with higher occurrences in the biofilm samples. CONCLUSION Our results underscore the importance of biofilms in water taps as hotspots for the dissemination of opportunistic bacteria and ARG within hospital environments. The identification of multiple opportunistic bacteria and ARGs raises concerns about the potential exposure and acquisition of HAIs, emphasizing the need for proactive measures, particularly in controlling biofilms, to mitigate infection risks in healthcare settings.

Abstract
Healthcare settings have a high prevalence of infectious agents. This narrative review examines the existing evidence regarding infection prevention and control (IPC) using the WHO Infection Prevention and Control Assessment Framework (IPCAF) tool in healthcare facilities. A total of 13 full length papers from Africa, Asia and Europe were considered for this review. The findings showed that there are discrepancies in the IPCAF values from insufficient to advanced level. The current review shows an advanced IPCAF level in middle income and high income countries. Low income countries showed a lower IPCAF score. There is a need to enhance the IPC capacity building and to supply infection prevention resources to prevent healthcare associated infection (HAI) with a focus on low income countries.

Abbas S. The challenges of implementing infection prevention and antimicrobial stewardship programs in resource-constrained settings. ANTIMICROBIAL STEWARDSHIP & HEALTHCARE EPIDEMIOLOGY : ASHE 2024; 4:e45. [PMID: 38628374 PMCID: PMC11019578 DOI: 10.1017/ash.2024.35] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 01/03/2024] [Revised: 02/07/2024] [Accepted: 02/10/2024] [Indexed: 04/19/2024]
Abstract
The burden of healthcare-associated infections (HAIs) and antimicrobial resistance (AMR) is disproportionately high in low and middle-income countries. Barriers to implementing effective antimicrobial stewardship and infection prevention programs include the lack of a structural framework, consensus guidelines, educational opportunities, trained personnel, funding, and access to resources such as manpower, information technology, and diagnostics. Socioeconomic instability with supply chain interruptions, poor skilled staff retention, absence of mandates, and inadequate support to enforce existing policies further aggravates the situation. Failure to implement measures to tackle AMR and HAIs effectively will result in repercussions globally.

Abstract
AIMS To measure nurses' compliance with standard precautions during the COVID-19 pandemic, compare findings with previous assessments and describe the barriers affecting nurses' compliance. BACKGROUND Healthcare providers' compliance with standard precautions is still limited worldwide. Implementation of infection control policies in hospitals is needed internationally, especially during a pandemic. Surprisingly, studies exploring nurses' compliance with standard precautions are lacking during COVID-19. METHODS A multicenter cross-sectional study was adopted in two Italian hospitals. Nurses' compliance with standard precautions was measured through The Compliance with Standard Precautions Scale (Italian version). An open-ended question explored the barriers to nurses' compliance with standard precautions. Reporting, followed the STROBE guidelines. RESULTS A total of 201 nurses were enrolled in 2020. Nurses' compliance with standard precautions was suboptimal. A statistically significant improvement in the compliance rate with standard precautions was observed between pre- and during COVID-19 assessments. High compliance was found in the appropriate use of surgical masks, gloves and sharps disposal. Nurses perceived personal, structural and organizational barriers to standard precautions adherence. CONCLUSION Nurses' compliance with standard precautions was not 100%, and different factors impeded nurses to work safely. Our findings provide institutional leaders and educators with the basis for implementing policies to optimize nurse safety, well-being and patient care. IMPLICATIONS FOR NURSING AND HEALTH POLICIES Nurses have the right to work safely, and when the shortage of personal protective equipment and nurses during an emergency threatens healthcare quality worldwide, policymakers are challenged to act by establishing an effective allocation of resources for consistent compliance with standard precautions. Moreover, nurses should actively engage in the implementation of infection control policies to improve safe behaviours among citizens and students accessing hospitals.

Abstract
Healthcare-associated infections (HAIs) are a global concern affecting millions of patients, requiring robust infection prevention and control measures. In particular, patients with traumatic brain injury (TBI) are highly susceptible to nosocomial infections, emphasizing the importance of infection control. Non-invasive near infrared spectroscopy (NIRS) device, CEREBO® integrated with a disposable component CAPO® has emerged as a valuable tool for TBI patient triage and this study evaluated the safety and efficacy of this combination. Biocompatibility tests confirmed safety and transparency assessments demonstrated excellent light transmission. Clinical evaluation with 598 enrollments demonstrated high accuracy of CEREBO® in detecting traumatic intracranial hemorrhage. During these evaluations, the cap fitted well and moved smoothly with the probes demonstrating appropriate flexibility. These findings support the efficacy of the CAPO® and CEREBO® combination, potentially improving infection control and enhancing intracranial hemorrhage detection for TBI patient triage. Ultimately, this can lead to better healthcare outcomes and reduced global HAIs.

Abstract
Understanding the healthcare provider costs of antimicrobial resistance (AMR) in lower-middle-income countries would motivate healthcare facilities to prioritize reducing the AMR burden. This study evaluates the extra length of stay and the associated healthcare provider costs due to AMR to estimate the potential economic benefits of AMR prevention strategies. We combined data from a parallel cohort study with administrative data from the participating hospitals. The parallel cohort study prospectively matched a cohort of patients with bloodstream infections caused by third-generation cephalosporin-resistant enterobacteria and methicillin-resistant Staphylococcus aureus (AMR cohort) with two control arms: patients infected with similar susceptible bacteria and a cohort of uninfected controls. Data collection took place from June to December 2021. We calculated the cost using aggregated micro-costing and step-down costing approaches and converted costs into purchasing power parity in international US dollars, adjusting for surviving patients, bacterial species and cost centres. We found that the AMR cohort spent a mean of 4.2 extra days (95% CI: 3.7-4.7) at Hospital 1 and 5.5 extra days (95% CI: 5.1-5.9) at Hospital 2 compared with the susceptible cohort. This corresponds to an estimated mean extra cost of $823 (95% CI: 812-863) and $946 (95% CI: US$929-US$964) per admission, respectively. For both hospitals, the estimated mean annual extra cost attributable to AMR was approximately US$650 000. The cost varies by organism and type of resistance expressed. The result calls for prioritization of interventions to mitigate the spread of AMR in Ghana.

Abstract
Background In resource-constrained settings, limited antibiotic options make treating carbapenem-resistant bacterial infections difficult for healthcare providers. This study aimed to assess carbapenemase expression in Gram-negative bacteria isolated from clinical samples in Jimma, Ethiopia. Methods A cross-sectional study was conducted to assess carbapenemase expression in Gram-negative bacteria isolated from patients attending Jimma Medical Center. Totally, 846 Gram-negative bacteria were isolated and identified using matrix-assisted laser desorption ionization-time of flight mass spectrometry (MALDI-TOF MS). Phenotypic antibiotic resistance patterns were determined using the Kirby-Bauer disk diffusion method and Etest strips. Extended-spectrum β-lactamase phenotype was determined using MAST disks, and carbapenemases were characterized using multiplex polymerase chain reactions (PCR). Results Among the isolates, 19% (157/846) showed phenotypic resistance to carbapenem antibiotics. PCR analysis revealed that at least one carbapenemase gene was detected in 69% (107/155) of these strains. The most frequently detected acquired genes were blaNDM in 35% (37/107), blaVIM in 24% (26/107), and blaKPC42 in 13% (14/107) of the isolates. Coexistence of two or more acquired genes was observed in 31% (33/107) of the isolates. The most common coexisting acquired genes were blaNDM + blaOXA-23, detected in 24% (8/33) of these isolates. No carbapenemase-encoding genes could be detected in 31% (48/155) of carbapenem-resistant isolates, with P. aeruginosa accounting for 85% (41/48) thereof. Conclusion This study revealed high and incremental rates of carbapenem-resistant bacteria in clinical samples with various carbapenemase-encoding genes. This imposes a severe challenge to effective patient care in the context of already limited treatment options against Gram-negative bacterial infections in resource-constrained settings.

Different evolution of S. aureus methicillin-resistant and methicillin-susceptible infections, Argentina. Heliyon 2024; 10:e22610.

Abstract
Staphylococcus aureus-(SA) is widespread among healthcare-associated-(HA) and the community-associated-(CA) infections. However, the contributions of MRSA and MSSA to the SA overall burden remain unclear. In a nationally-representative-survey conducted in Argentina, 668 SA clinical isolates from 61 hospitals were examined in a prospective, cross-sectional, multicenter study in April 2015. The study aimed to analyze MRSA molecular epidemiology, estimate overall SA infection incidence (MSSA, MRSA, and genotypes) in community-onset (CO: HACO, Healthcare-Associated-CO and CACO, Community-Associated-CO) and healthcare-onset (HO: HAHO, Healthcare-associated-HO) infections, stratified by age groups. Additionally temporal evolution was estimated by comparing this study's (2015) incidence values with a previous study (2009) in the same region. Erythromycin-resistant-MSSA and all MRSA strains were genetically typed. The SA total-infections (TI) overall-incidence was 49.1/100,000 monthly-visits, 25.1 and 24.0 for MRSA and MSSA respectively (P = 0.5889), in April 2015. In adults with invasive-infections (INVI), MSSA was 15.7 and MRSA was 11.8 (P = 0.0288), 1.3-fold higher. HA SA infections, both MSSA and MRSA, surpassed CA infections by over threefold. During 2009-2015, there was a significant 23.4 % increase in the SA infections overall-incidence, mainly driven by MSSA, notably a 54.2 % increase in INVI among adults, while MRSA infection rates remained stable. The MSSA rise was accompanied by increased antimicrobial resistance, particularly to erythromycin, linked to MSSA-CC398-t1451-ermT + -IEC+-pvl- emergence. The SA-infections rise was primarily attributed to community-onset-infections (37.3 % and 62.4 % increase for TI and INVI, respectively), particularly HACO-MSSA and HACO-MRSA in adults, as well as CACO-MSSA. The main CA-MRSA-PFGE-typeN-ST30-SCCmecIVc-PVL+/- clone along with other clones (USA300-ST8-IV-LV-PVL+/-, PFGE-typeDD-ST97-IV- PVL-) added to rather than replaced CA-MRSA-PFGE-typeI-ST5-SCCmecIVa-PVL+/- clone in HA invasive-infections. They also displaced clone HA-MRSA-PFGE-typeA-ST5-SCCmecI, mainly in HAHO infections. The overall-burden of SA infections is rising in Argentina, driven primarily by community-onset MSSA, particularly in adults, linked to increased erythromycin-resistance and MSSA-CC398-t1451-ermT + -IEC+-pvl- emergence. Novel knowledge and transmission-control strategies are required for MSSA.

Abstract
BACKGROUND Healthcare-associated infections (HAIs) increase morbidity, mortality and costs. The overall prevalence of HAIs is greater in low- and middle-income countries due to poor resources and infrastructure, with the incidence of HAIs greater among neonates and children. There is a need to understand the current situation in Pakistan including key drivers to improve future care. METHODS Point prevalence survey (PPS) of HAIs in the children's wards of 19 public sector secondary- and tertiary-care hospitals of Pakistan and associated key drivers. RESULTS A total of 1147 children were included in the PPS. 35.7% were neonates with 32.8% aged >1-5 years. 35.2% were admitted to the intensive care units (ICUs). Peripheral, central venous and urinary catheters were present in 48%, 2.9% and 5.6% of the patients, respectively. A total of 161 HAIs from various pathogens were observed in 153 cases, giving a prevalence of 13.3%. The majority of HAIs were caused by Staphylococcus aureus (31.7%) followed by Klebsiella pneumoniae (22.9%) and Escherichia coli (17.4%). Bloodstream infections were identified in 42 cases followed by lower-respiratory-tract infections in 35. Increased length of hospital stays and being admitted to the ICU, 'rapidly fatal' patients under the McCabe and Jackson criteria, central and peripheral catheterization, and invasive mechanical ventilation were, associated with higher HAIs (P<0.001). 99.7% of HAI patients fully recovered and were discharged from the hospital. CONCLUSION There is a high prevalence of HAIs among neonates and children admitted to health facilities in Pakistan. Infection prevention and control measures should be implemented to help prevent future HAIs.

Abstract
Aim: To investigate the outbreak of Burkholderia cepacia complex (BCC), mortality, antimicrobial resistance and associated risk factors in the neonatal intensive care unit. Method: Eighteen blood culture samples from neonates and twenty swab samples from different neonatal intensive care unit surfaces were collected. The VITEK 2 was used to confirm the isolates and generate the antibiogram. PCR was used to identify blaNDM. Results: Eighteen samples tested positive for BCC, and 10/18 (55.5%) of the neonates died. 13/18 (72%) of the neonates had late-onset neonatal sepsis, and 10/18 (55%) had low birth weight. Resistance to minocycline and chloramphenicol was 100%, 72.2% to meropenem; 72.2% NDM gene was found in neonates and was 20% from the environment. Conclusion: Outbreak of NDM-producing BCC resulting in high neonatal mortality in NICU.

Abstract
Bioactive substances such as phenolic compounds, antioxidants, and antibacterial agents are found in natural fibres. In this study, banana fibre was extracted from the trunks of banana plants. Antibacterial activity, FTIR, XRD, and SEM analysis were performed to characterize the banana cellulose fibre, and also raw and alkali-treated banana fibre composite was fabricated with an epoxy matrix. Results of the antibacterial analysis indicate that this banana cellulose fibre strongly impedes bacterial growth with elevated inhibitory zones. The primary peaks observed at 1170 cm-1 and 1426 cm-1 by FTIR analysis correspond to C-O stretching, O-H bending, aliphatic ether, secondary alcohol, and carboxylic acid. The morphological analysis reveals the fibre quality, and the EDX analysis confirms the elements present in the banana cellulose fibre. The XRD results demonstrated a more significant proportion (76.8%) of the amorphous region. This study indicates that banana cellulose fibre could be a promising source of antimicrobial compounds. In addition, the mechanical properties of alkali-treated banana fibre composite were preferable to raw fibre composite by an average of 3% for this banana fibre composite. As a result, this composite can be used to manufacture automobile interior components, as it can reduce the sanitizing periods of interior components during winter months.

Abstract
Background Aseptic techniques are crucial in preventing healthcare-associated infections, which are an integral part of standard precautions, and encompass a range of practices designed to safeguard patients from healthcare-associated infections. Objective The objective of this study was to evaluate the level of knowledge and identify the barriers faced by nursing staff in implementing aseptic techniques. Methodology This study employed a stratified random sampling technique to ensure the representation of the research sample. A cross-sectional, descriptive research design was used to assess the knowledge and barriers of nursing staff in maintaining aseptic techniques in their medical practice at Khartoum Teaching Hospital, Sudan. The nursing staff members were divided into different units, and a proportionate number of participants were randomly selected from each stratum. A total of 83 nursing staff members were recruited for this study. Data collection was conducted using a structured questionnaire specifically designed for this study. The questionnaire consisted of items that assessed the nursing staff's knowledge and barriers to aseptic technique implementation. Results The study findings revealed that the mean knowledge score of nursing staff was 14.12, with a median score of 15. The knowledge score had a standard deviation of 3.22. Approximately two-thirds of the nurses (66.3%) had an average level of knowledge, while 33.7% had a below-average level of knowledge. The chi-square analysis indicated a significant association between educational level, years of experience, and knowledge scores (P value=0.010) at a significance level of 0.05. Additionally, 65% of the participants reported facing multiple challenges in maintaining aseptic techniques, including insufficient training, limited resources, and inadequate support. Conclusion In conclusion, the evaluation revealed that a significant proportion of participants felt that their unit lacked adequate training and resources for aseptic techniques. Many had observed colleagues not adhering to aseptic practices, and the participants faced multiple challenges in maintaining aseptic techniques, including insufficient training, limited resources, time constraints, and inadequate support.

Abstract
INTRODUCTION The management of invasive fungal infections (IFIs) in low- and middle-income countries (LMIC) is a serious challenge due to limited epidemiology studies, sub-optimal laboratory facilities, gap in antifungal management training and resources. Limited studies highlighted distinctive epidemiology of IFIs in those countries, and difficulty in distinguishing from closely related infections. To overcome the gaps for appropriate management of IFIs, innovative approaches are required. AREAS COVERED Extensive literature search and discussion with experts have helped us to summarize the epidemiology, diagnostic and management difficulties in managing IFIs in LMIC, and recommend certain solutions to overcome the challenges. EXPERT OPINION The strategies to overcome the challenges in diagnosis may include local epidemiology study, training of healthcare workers, association of fungal infections with already existing budgeted national programs, development and incorporation of point-of-care test (POCT) for prompt diagnosis, simplifying clinical diagnostic criteria suitable for LMIC, judicious use of available expertise, and diagnostic stewardship. For management strategies judicious use of antifungal, partnering with industry for inexpensive antifungal agents, development of LMIC specific guidelines for cost-effective management of IFIs and fungal outbreaks, improvement of infection control practices, advocacy for implementation of WHO recommended antifungal use, and integration of IFIs with public health.

Abstract
BACKGROUND Health care associated infections (HCAIs) are a global challenge and hand hygiene is the primary measure to reduce these. In developing countries, patients are between 2 and 20 times more likely to acquire an HCAI compared with developed countries. Estimates of hand hygiene in Sub-Saharan Africa suggests 21% concordance. There are few studies investigating barriers and facilitators and those published tend to be surveys. This study aimed to understand barriers and facilitators to hand hygiene in a hospital in Nigeria. METHODS A theoretically underpinned in-depth qualitative interview study with thematic analysis of nurses and doctors working in surgical wards. RESULTS There were individual and institutional factors constituting barriers or facilitators: (1) knowledge, skills, and education, (2) perceived risks of infection to self and others, (3) memory, (4) the influence of others and (5) skin irritation. Institutional factors were (1) environment and resources and (2) workload and staffing levels. CONCLUSIONS Our study presents barriers and facilitators not previously reported and offers nuances and detail to those already reported in the literature. Although the primary recommendation is adequate resources, however small local changes such as gentle soap, simple skills and reminder posters and mentorship or support could address many of the barriers listed.

Abstract
INTRODUCTION Healthcare-associated infections (HAIs) have become a serious public health problem. Despite the fact that implementing evidence-based infection control strategies could prevent HAIs and save billions of dollars, Ethiopia lacks national surveillance studies on the rate, economic, and clinical burden of HAIs. OBJECTIVE To assess the clinical and economic burden of HAIs in hospitalized patients at Ayder comprehensive specialized hospital. MATERIALS AND METHODS A prospective cohort study design was conducted in patients with and without HAIs. A review of medical records, interviews, and patient bills was used to extract necessary information. The patients in the two arms were matched based on age, sex, Charlson comorbidity index, and ward type. Measurable factors were compared between infected and uninfected patients using the paired ttest or McNemar's test, as appropriate. Logistic regression was used to identify predictors of in-hospital mortality. Stata 14.1 was used to conduct all analyses. RESULTS A total of 408 patients, 204 with HAIs and 204 without HAIs were included in the study. In-hospital mortality was higher in patients with HAI (14.7% vs 7.8%, P = 0.028). Patients with HAI stayed an average of 8.3 days longer than controls (18.85 vs 10.59, P<0.001). The average direct medical costs for patients with HAI were 3033 Ethiopian birrs (ETB) higher than controls (4826 vs 1793, P<0.001). The presence of HAIs (AOR: 2.22, 95% CI: 1.13-4.39) and admission to intensive care units (AOR: 3.39, 95% CI: 1.55-7.40) were significant predictors of in-hospital mortality. CONCLUSION HAIs have a significant impact on in-hospital mortality, the length of extra hospital stays, and extra costs for medical care. Patients admitted to intensive care units and those with HAIs were found to be significant predictors of in-hospital mortality. Interventions must be implemented to prevent HAIs, especially in patients admitted to intensive care units.

Associations of socioeconomic status with infectious diseases mediated by lifestyle, environmental pollution and chronic comorbidities: a comprehensive evaluation based on UK Biobank. Infect Dis Poverty 2023; 12:5.

Abstract
BACKGROUND Socioeconomic status (SES) inequity was recognized as a driver of some certain infectious diseases. However, few studies evaluated the association between SES and the burden of overall infections, and even fewer identified preventable mediators. This study aimed to assess the association between SES and overall infectious diseases burden, and the potential roles of factors including lifestyle, environmental pollution, chronic disease history. METHODS We included 401,009 participants from the UK Biobank (UKB) and defined the infection status for each participant according to their diagnosis records. Latent class analysis (LCA) was used to define SES for each participant. We further defined healthy lifestyle score, environment pollution score (EPS) and four types of chronic comorbidities. We used multivariate logistic regression to test the associations between the four above covariates and infectious diseases. Then, we performed the mediation and interaction analysis to explain the relationships between SES and other variables on infectious diseases. Finally, we employed seven types of sensitivity analyses, including considering the Townsend deprivation index as an area level SES variable, repeating our main analysis for some individual or composite factors and in some subgroups, as well as in an external data from the US National Health and Nutrition Examination Survey, to verify the main results. RESULTS In UKB, 60,771 (15.2%) participants were diagnosed with infectious diseases during follow-up. Lower SES [odds ratio (OR) = 1.5570] were associated with higher risk of overall infections. Lifestyle score mediated 2.9% of effects from SES, which ranged from 2.9 to 4.0% in different infection subtypes, while cardiovascular disease (CVD) mediated a proportion of 6.2% with a range from 2.1 to 6.8%. In addition, SES showed significant negative interaction with lifestyle score (OR = 0.8650) and a history of cancer (OR = 0.9096), while a significant synergy interaction was observed between SES and EPS (OR = 1.0024). In subgroup analysis, we found that males and African (AFR) with lower SES showed much higher infection risk. Results from sensitivity and validation analyses showed relative consistent with the main analysis. CONCLUSIONS Low SES is shown to be an important risk factor for infectious disease, part of which may be mediated by poor lifestyle and chronic comorbidities. Efforts to enhance health education and improve the quality of living environment may help reduce burden of infectious disease, especially for people with low SES.

Abstract
Healthcare-associated infections (HAI), or nosocomial infections, are a global health and economic problem in developed and developing countries, particularly for immunocompromised patients in their intensive care units (ICUs) and surgical site hospital areas. Recurrent pathogens in HAIs prevail over antibiotic-resistant bacteria, such as methicillin-resistant Staphylococcus aureus (MRSA) and Pseudomonas aeruginosa. For this reason, natural antibacterial mechanisms are a viable alternative for HAI treatment. Natural fibers can inhibit bacterial growth, which can be considered a great advantage in these applications. Moreover, these fibers have been reported to be biocompatible and biodegradable, essential features for biomedical materials to avoid complications due to infections and significant immune responses. Consequently, tissue engineering, medical textiles, orthopedics, and dental implants, as well as cosmetics, are fields currently expanding the use of plant fibers. In this review, we will discuss the source of natural fibers with antimicrobial properties, antimicrobial mechanisms, and their biomedical applications.

Abstract
Nosocomial or healthcare-associated infection (HCAI) is an infection acquired during receiving health care that was not present during admission. The research aimed to determine the antibiotic susceptibility pattern of gram-positive bacteria isolated from Primary Health Centers in Jega Town. A total of fifty (50) swab samples were collected from 10 different health centers and analyzed using the streak plate technique. Pure bacterial isolates were maintained and characterized using biochemical tests; their percentage of occurrence show; Staphylococcus aureus 18 (43.9%), Enterococcus feacalis 8 (19.5%), Streptococcus spp 8 (19.5%), Bacillus cereus 4 (9.8%), and Staphylococcus epidermidis 3 (7.3%). McFarland standard solution was prepared and used to control inoculants, after which the antibiotic susceptibility pattern of the isolates was determined using the disc diffusion method. Staphylococcus epidermidis was resistant to Gentamycin, and other isolates were multi-drug resistant. In light of this research, there is a need for thorough disinfection and conscientious contact control procedures to minimize the spread of these pathogens in health centers where interaction between patients, HCWs, and caregivers is widespread and frequent.

Abstract
Healthcare-associated infections (HAIs) continue to cause patient harm and at increasing rates. Factors contributing to this increase include suboptimal hand hygiene, antimicrobial resistance, and inadequate decontamination of the patient environment and shared patient equipment. To reduce the risk of HAIs and enhance patient safety, it is important that nurses and other healthcare professionals adhere to infection prevention and control guidance, including decontamination procedures. It is also important to identify and address the barriers that can affect adherence to this guidance. This article discusses effective decontamination of the patient environment and non-critical shared patient equipment, the barriers to adhering to guidance and strategies for improving decontamination procedures.

Infect Drug Resist 2022; 15:837-850. [PMID: 35281573 PMCID: PMC8904264 DOI: 10.2147/idr.s349358] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/14/2021] [Accepted: 02/22/2022] [Indexed: 11/23/2022] Open
Abstract
Background Globally, HAIs affect about 2 million people annually and result in 5% to 15% hospitalizations. In low-middle-income countries, antibiotics are improperly prescribed for 44% to 97% of hospitalized patients. A report in Ethiopia revealed that about 66.7% of HAIs are managed inappropriately. Objective To identify inappropriate antimicrobial therapy (AMT) and its risk factors among patients with HAIs at Jimma Medical Center (JMC). Methods A prospective observational study was conducted involving 300 patients with HAIs in medical, surgical, and gynecology-obstetrics wards of JMC, from October 2020 to April 2021. Data were collected using data abstraction format. Logistic regression was conducted to assess factors associated with AMT inappropriateness. A p-value <0.05 was considered to declare statistical significance. Results The overall mean age (± standard deviation) of the participants was 43.2 ± 19.2 years and 183 (61.0%) of them were females. About three-fourths (76.0%) of patients with HAIs were treated inappropriately. Hospital-acquired pneumonia (50.3%) was the most common type of HAI identified in this study. The frequent class of inappropriate AMT was an inappropriate choice, 102 (44.1%), followed by an inappropriate dose, 88 (38.1%), and inappropriate indication, 59 (24.2%). On multivariable logistic regression, patients having culture finding (AOR = 0.32, p = 0.016), taking metronidazole (AOR = 0.25, p = 0.001), and taking vancomycin (AOR = 2.93, p = 0.001) were significantly associated with inappropriate AMT. Conclusion Inappropriate AMT was identified in about three-fourths of the patients with HAIs. A decrease in the likelihood of inappropriate AMT was identified in patients having culture findings and in those taking metronidazole, whereas taking vancomycin increased the likelihood of inappropriate AMT. Therefore, the authors recommend scaling up the capacity of definitive therapy through culture and sensitivity tests. Furthermore, training of prescribers in the rational use of antimicrobials is also warranted.

Confl Health 2021; 15:94. [PMID: 34930364 PMCID: PMC8686079 DOI: 10.1186/s13031-021-00428-8] [Citation(s) in RCA: 19] [Impact Index Per Article: 6.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/19/2021] [Accepted: 11/29/2021] [Indexed: 12/13/2022] Open
Abstract
Background Healthcare associated infections (HAIs) are the most frequent adverse outcome in healthcare delivery worldwide. In conflict-affected settings HAIs, in particular surgical site infections, are prevalent. Effective infection prevention and control (IPC) is crucial to ending avoidable HAIs and an integral part of safe, effective, high quality health service delivery. However, armed conflict and widespread violence can negatively affect the quality of health care through workforce shortages, supply chain disruptions and attacks on health facilities and staff. To improve IPC in these settings it is necessary to understand the specific barriers and facilitators experienced locally. Methods In January and February of 2020, we conducted semi-structured interviews with hospital staff working for the International Committee of the Red Cross across eight conflict-affected countries (Central African Republic, South Sudan, Democratic Republic of the Congo, Mali, Nigeria, Lebanon, Yemen and Afghanistan). We explored barriers and facilitators to IPC, as well as the direct impact of conflict on the hospital and its’ IPC programme. Data was analysed thematically. Results We found that inadequate hospital infrastructure, resource and workforce shortages, education of staff, inadequate in-service IPC training and supervision and large visitor numbers are barriers to IPC in hospitals in this study, similar to barriers seen in other resource-limited settings. High patient numbers, supply chain disruptions, high infection rates and attacks on healthcare infrastructures, all as a direct result of conflict, exacerbated existing challenges and imposed an additional burden on hospitals and their IPC programmes. We also found examples of local strategies for improving IPC in the face of limited resources, including departmental IPC champions and illustrated guidelines for in-service training. Conclusions Hospitals included in this study demonstrated how they overcame certain challenges in the face of limited resources and funding. These strategies present opportunities for learning and knowledge exchange across contexts, particularly in the face of the current global coronavirus pandemic. The findings are increasingly relevant today as they provide evidence of the fragility of IPC programmes in these settings. More research is required on tailoring IPC programmes so that they can be feasible and sustainable in unstable settings.
