Infection control practices in public sector hospitals of Punjab: a critical analysis.

INTRODUCTION: Infection prevention and control (IPC) is imperative towards patient safety and health. The Infection Prevention and Control Assessment Framework (IPCAF) developed by WHO provides a baseline assessment at the acute healthcare facility level. This study aimed to assess the existing IPC level of selected public sector hospital facilities in Punjab to explore their strengths and deficits. METHODS: Between October and April 2023, 11 public sector hospitals (including tertiary, secondary and primary level care) were selected. Data were collected using the IPCAF assessment tool comprising eight sections, which were then categorised into four distinct IPC levels- inadequate, basic, intermediate and advanced. Key performance metrics were summarised within and between hospitals. RESULTS: The overall median IPCAF score for the public sector hospitals was 532.5 (IQR: 292.5-690) out of 800. Four hospitals each scored 'advanced' as well as 'basic' IPC level and three hospitals fell into 'intermediate level'. Most hospitals had IPC guidelines as well as IPC programme, environments, materials and equipments. Although 90% of secondary care hospitals had IPC education and training, only 2 out of 5 (40%) tertiary care and 2 out of 3 (67%) primary care hospitals have IPC or additional experts for training. Only 1 out of 5 tertiary care hospitals (20%) were recorded in an agreed ratio of healthcare workers to patients while 2 out of 5 (40%) of these hospitals lack staffing need assessment. CONCLUSION: Overall the sampled public sector (tertiary, secondary and primary) hospitals demonstrated satisfactory IPC level. Challenging areas are the healthcare-associated infection surveillance, monitoring/audit and staffing, bed occupancy overall in all the three categories of hospitals. Periodic training and assessment can facilitate improvement in public sector systems.

Magnitude of standard precautions practices among healthcare workers in health facilities of Low and Middle Income Countries: A systematic review and meta-analysis.

BACKGROUND: Standard precautions are the minimum standard of infection control to prevent transmission of infectious agents, protect healthcare workers, patients, and visitors regardless of infection status. The consistent implementation of standard precautions is highly effective in reducing transmission of pathogens that cause HAIs. Despite their effectiveness, compliance, resources, patient behavior, and time constraints are some of the challenges that can arise when implementing standard precautions. The main objective of this meta-analysis was to show the pooled prevalence of safe standard precaution practices among healthcare workers in Low and Middle Income Countries (LMICs). METHODS: A systematic review and meta-analysis was conducted for this study. We systematically searched observational study articles from PubMed Central and Google Scholar. We included articles published any year and involving healthcare workers. We used Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA). The random effect model was used to estimate the pooled prevalence. The meta-analysis, sensitivity analysis, subgroup analysis, and publication bias (funnel plot, and Egger's tests) were conducted. RESULTS: A total of 46 articles were included in this study. The pooled prevalence of standard precautions practices among healthcare workers in LMICs was 53%, with a 95% CI of (47, 59). These studies had a total sample size of 14061 with a minimum sample size of 17 and a maximum sample size of 2086. The majority of the studies (82.6%) were conducted in hospitals only (all kinds), and the remaining 17.4% were conducted in all health facilities, including hospitals. CONCLUSIONS: The pooled prevalence of standard precautions practices among healthcare workers in LMICs was suboptimal. The findings of this study can have substantial implication for healthcare practice and policy making by providing robust evidence with synthesized and pooled evidence from multiple studies.

Recommendations for the Cleaning of Endocavity Ultrasound Transducers Between Patients.

The COVID-19 pandemic highlighted the importance of infection prevention and control measures for all medical procedures, including ultrasound examinations. As the use of ultrasound increases across more medical modalities, including point-of-care ultrasound, so does the risk of possible transmission from equipment to patients and patients to patients. This is particularly relevant for endocavity transducers, such as trans-vaginal, trans-rectal and trans-oesophageal, which could be contaminated with organisms from blood, mucosal, genital or rectal secretions. This article proports to update the WFUMB 2017 guidelines which focussed on the cleaning and disinfection of trans-vaginal ultrasound transducers between patients.

Healthcare-associated infection management in 62 ICUs for patients with congenital heart disease in China: a survey study.

OBJECTIVES: All patients with congenital heart disease (CHD) receive postoperative management in ICUs. Infection prevention and control (IPC) has a significant impact on prognosis. This study provides a preliminary understanding of the fundamental aspects of IPC in ICUs following CHD surgery in China. METHODS: From September to October 2023, we initiated a survey on healthcare-associated infection (HAI) management in hospitals that perform CHD surgeries independently. The questionnaires were jointly completed by the ICU physicians and IPC personnel. Duplicate or unqualified questionnaires were excluded from the study. The contents of our questionnaires covered hospital and ICU capacity, performance of the infection control department, HAI surveillance, implementation of IPC measures, and antimicrobial stewardship (AMS). Qualified questionnaires were compared according to the volume of annual CHD surgeries performed in different ICUs. Group 1 was defined as volume more than 300 cases and group 2 was defined as volume less than or equal to 300 cases. RESULTS: Sixty-two of the 118 questionnaires were completed, with a response rate of 53%. The CHD surgical volume in 2022 of the 62 hospitals was 36342, accounting for 52% of the annual CHD surgical volume (69 672) across the country. The postoperative infection rates obtained from the 15 ICUs varied from 1.3 to 15%, with a median rate of 4.5%. A total of 16 ICUs provided data on drug-resistant bacteria, Klebsiella pneumoniae exhibiting the highest frequency. More than 95% of ICUs have established complete HAI management systems. Information-based HAI surveillance was conducted in 89% of ICUs. Approximately 67% of ICUs stopped prophylactic antibiotics within 48 hours after surgery. In complex cases, carbapenems were administered empirically in 89% of ICUs. Group 1 had an advantage over group 2 in preventing multi-drug-resistant organisms (all instruments should be used alone 100% vs. 86%, P =0.047; cleaning and disinfection of environmental surfaces, 100% vs. 81%, P =0.035; antibiotic consumption control 85% vs. 61%, P =0.044) and in preventing surgical site infections (perioperative blood glucose monitoring, 88% vs. 67%, P =0.048). However, Group 1 did not perform well in preventing catheter-related bloodstream infection (delayed catheter removal due to convenience of laboratory tests, 31% vs. 6%, P =0.021) and catheter-associated urinary tract infection (delayed catheter removal due to muscle relaxant administration, 88% vs. 58%, P =0.022). CONCLUSIONS: A relatively complete HAI management system has been established throughout the country in ICUs for CHD patients. Information-based surveillance of HAI needs to be promoted, and actions should be taken to facilitate the implementation of IPC measures and AMS bundles. Training and feedback are critical for implementing IPC measures.

Compliance with central venous catheter infection prevention practices after intervention with simulation.

OBJECTIVES: to assess the effect of an educational intervention based on clinical simulation on nursing professionals' compliance with practices to prevent peripherally inserted central venous catheter-associated primary bloodstream infections in a Neonatal Intensive Care Unit. METHODS: a quasi-experimental study, with preand post-intervention assessment with a single group. The population consisted of 41 nursing professionals, with 31 observations being made before and after the intervention. Analyzes were performed using descriptive statistics and the McNemar non-parametric test. A significance level of 5% was adopted. RESULTS: after the intervention, there was an increase in compliance with prevention practices of surgical antisepsis and professional hand hygiene, skin antisepsis with chlorhexidine, waiting for the time of the effect of alcoholic chlorhexidine and compliance with the sterile technique. CONCLUSIONS: the educational intervention showed an effect on increasing compliance with catheter-associated infection prevention practices.

New safer management for breast cancer patients who need neoadjuvant therapy during SARS-COVID pandemic.

During the first hit of SARS-COVID pandemic, an important reorganization of Healthcare Services has been done, and new protocols and pathways to protect frail patients like oncological patients were designed. The second hit of pandemic had stressed these new pathways and suggests to health-workers some improvements for safer management of patents.We reported our experience in organizing the clinical pathway of neoadjuvant therapy candidate patients based on the execution of sentinel lympho-node biopsy and the placement of implantable venous access port in the same access to operating room before neoadjuvant chemotherapy suggesting a possible organizational model. In the period October-December 2020 we have included in this new type of path twelve patients and we have not registered any cases of COVID among the patients included. We think this new path, adopted amid the second hit, will be useful for all Breast Units that are facing the challenge of guaranteeing the highest standards of care in a historical moment where the health emergency occupies the efforts of health workers and the economic resources of health systems.

Infection control in the intensive care unit: expert consensus statements for SARS-CoV-2 using a Delphi method.

During the current COVID-19 pandemic, health-care workers and uninfected patients in intensive care units (ICUs) are at risk of being infected with SARS-CoV-2 as a result of transmission from infected patients and health-care workers. In the absence of high-quality evidence on the transmission of SARS-CoV-2, clinical practice of infection control and prevention in ICUs varies widely. Using a Delphi process, international experts in intensive care, infectious diseases, and infection control developed consensus statements on infection control for SARS-CoV-2 in an ICU. Consensus was achieved for 31 (94%) of 33 statements, from which 25 clinical practice statements were issued. These statements include guidance on ICU design and engineering, health-care worker safety, visiting policy, personal protective equipment, patients and procedures, disinfection, and sterilisation. Consensus was not reached on optimal return to work criteria for health-care workers who were infected with SARS-CoV-2 or the acceptable disinfection strategy for heat-sensitive instruments used for airway management of patients with SARS-CoV-2 infection. Well designed studies are needed to assess the effects of these practice statements and address the remaining uncertainties.

Experiences of the SARS-CoV-2 pandemic amongst Australian healthcare workers: from stressors to protective factors.

BACKGROUND: The SARS-CoV-2 pandemic has critically challenged healthcare systems globally. Examining the experiences of healthcare workers (HCWs) is important for optimizing ongoing and future pandemic responses. OBJECTIVES: In-depth exploration of Australian HCWs' experiences of the SARS-CoV-2 pandemic, with a focus on reported stressors vis-à-vis protective factors. METHODS: Individual interviews were performed with 63 HCWs in Australia. A range of professional streams and operational staff were included. Thematic analysis was performed. RESULTS: Thematic analysis identified stressors centred on paucity of, or changing, evidence, leading to absence of, or mistrust in, guidelines; unprecedented alterations to the autonomy and sense of control of clinicians; and deficiencies in communication and support. Key protective factors included: the development of clear guidance from respected clinical leaders or recognized clinical bodies, interpersonal support, and strong teamwork, leadership, and a sense of organizational preparedness. CONCLUSIONS: This study provides insights into the key organizational sources of emotional stress for HCWs within pandemic responses and describes experiences of protective factors. HCWs experiencing unprecedented uncertainty, fear, and rapid change, rely on clear communication, strong leadership, guidelines endorsed by recognized expert groups or individuals, and have increased reliance on interpersonal support. Structured strategies for leadership and communication at team, service group and organizational levels, provision of psychological support, and consideration of the potential negative effects of centralizing control, would assist in ameliorating the extreme pressures of working within a pandemic environment.

Phenotypic and molecular characterization of fluoroquinolone resistant Pseudomonas aeruginosa isolates in Palestine / Caracterização fenotípica e molecular de isolados de Pseudomonas aeruginosa resistentes a fluoroquinolonas na Palestina

Fluoroquinolones are important antimicrobial agents for the treatment of Pseudomonas infections. A total of 11 isolates of P. aeruginosa were collected from different clinical samples from different medical centers in the North West Bank-Palestine during 2017. In this study, resistance to fluoroquinolones and secretions of β-lactamases were detected by phenotypic methods, while presence of β-lactamase gene sequences and other virulence factors were detected by PCR technique. PCR product for gyrA, parC and parE genes were sequenced for further analyses. The phylogenetic analyses, population diversity indices and haplotypes determination were conducted using computer programs MEGA version 6, DnaSP 5.1001 and median-joining algorithm in the program Network 5, respectively. Results of this study showed that the MIC for ciprofloxacin and norfloxacin had a range of 32-256 µg/ml. In addition, all isolates carried either exoT or exoT and exoY genes, different β-lactamase genes and 82% of these isolates harbored class 1 integrons. Analyses of the gyrA, parC and parE sequences were found to be polymorphic, had high haplotype diversity (0.945-0.982), low nucleotide diversity (0.01225-0.02001) and number of haplotypes were 9 for each gyrA and parE genes and 10 haplotypes for parC gene. The founder haplotypes being Hap-1 (18%), Hap-2 (27.3%) and Hap-6 (9.1%) for gyrA, parC and parE genes, respectively. Two of ParE haplotypes were detected as indel haplotypes. The Median-joining- (MJ) networks constructed from haplotypes of these genes showed a star-like expansion. The neutrality tests (Tajima’s D test and Fu’s Fs test) for these genes showed negative values. Palestinian fluoroquinolone resistant P. aeruginosa strains showed high MIC level for fluoroquinolones, β-lactamase producers, carried type III secretion exotoxin-encoding genes, most of them [...].

Fluoroquinolonas são agentes antimicrobianos importantes para o tratamento de infecções por Pseudomonas. Um total de 11 bacilos isolados de P. aeruginosa foram coletados de diferentes amostras clínicas provenientes de diferentes centros médicos na Cisjordânia-Palestina durante o ano de 2017. Neste estudo, resistência a fluoroquinolonas e secreções de β-lactamases foram detectadas por métodos fenotípicos, enquanto a presença de sequências do gene β-lactamase e outros fatores de virulência foram detectados pela técnica de PCR (Proteína C-reativa). O produto de PCR para os genes gyrA, parC e parE foram sequenciados para análises posteriores. As análises filogenéticas, os índices de diversidade populacional e a determinação de haplótipos foram realizados utilizando os softwares MEGA versão 6, DnaSP 5.1001 e o algoritmo de junção de mediana do programa Network 5, respectivamente. Os resultados deste estudo mostraram que a MIC para ciprofloxacina e norfloxacina tinha um intervalo de 32-256 µg/ml. Além disso, todos os bacilos isolados carregavam genes exoT ou exoT e exoY, genes de β-lactamase diferentes e 82% desses isolados continham integrons de classe 1. As análises das sequências gyrA, parC e parE foram consideradas polimórficas, com alta diversidade de haplótipos (0,945-0,982), baixa diversidade de nucleotídeos (0,01225-0,02001) e o número de haplótipos foi de 9 para cada gene de gyrA e parE e 10 haplótipos para o gene parC. Os haplótipos fundadores são Hap-1 (18%), Hap-2 (27,3%) e Hap-6 (9,1%) para os genes gyrA, parC e parE, respectivamente. Dois dos haplótipos parE foram detectados como haplótipos InDel. As redes Median-joining (MJ) construídas a partir de haplótipos desses genes mostraram uma expansão semelhante à de uma estrela. Os testes de neutralidade (teste D de Tajima e teste Fs de Fu) para esses genes apresentaram valores negativos. As cepas palestinas de P. aeruginosa resistentes a fluoroquinolonas mostraram alto nível de MIC para [...].

Perform hand hygiene and the doors will open - the effectiveness of new system implementation on paediatric intensive care unit visitors' handwashing compliance.

Hand hygiene (HH) performance on entering intensive care units (ICUs) is commonly accepted but often inadequately performed. We developed a simple, inexpensive module that connects touchless dispensers of alcohol sanitiser (TDAS) to the automatic doors of a paediatric ICU, and assessed the impact of this intervention on HH compliance of hospital staff and visitors. A prospective observational study was conducted over a 3-week period prior to the intervention, followed by a 4-week period post intervention. HH performance was monitored by a research assistant whose office location enabled direct and video-assisted observation of the ICU entrance. A total of 609 entries to the ICU was recorded. Overall HH performance was 46.9% (92/196) before and 98.5% (406/413) after the intervention. Our findings suggest that HH performance on entering an ICU can be improved via a mechanism that makes operation of an automatic door dependent on use of a TDAS system, and thus contribute to infection control.

A narrative review on current duodenoscope reprocessing techniques and novel developments.

Duodenoscopy-associated infections occur worldwide despite strict adherence to reprocessing standards. The exact scope of the problem remains unknown because a standardized sampling protocol and uniform sampling techniques are lacking. The currently available multi-society protocol for microbial culturing by the Centers for Disease Control and Prevention, the United States Food and Drug Administration (FDA) and the American Society for Microbiology, published in 2018 is too laborious for broad clinical implementation. A more practical sampling protocol would result in increased accessibility and widespread implementation. This will aid to reduce the prevalence of duodenoscope contamination. To reduce the risk of duodenoscopy-associated pathogen transmission the FDA advised four supplemental reprocessing measures. These measures include double high-level disinfection, microbiological culturing and quarantine, ethylene oxide gas sterilization and liquid chemical sterilization. When the supplemental measures were advised in 2015 data evaluating their efficacy were sparse. Over the past five years data regarding the supplemental measures have become available that place the efficacy of the supplemental measures into context. As expected the advised supplemental measures have resulted in increased costs and reprocessing time. Unfortunately, it has also become clear that the efficacy of the supplemental measures falls short and that duodenoscope contamination remains a problem. There is a lot of research into new reprocessing methods and technical applications trying to solve the problem of duodenoscope contamination. Several promising developments such as single-use duodenoscopes, electrolyzed acidic water, and vaporized hydrogen peroxide plasma are already applied in a clinical setting.

Cross-infection and infection control in dental clinics in Nablus and Tulkarm districts.

BACKGROUND: Infection control had many developments in the COVID 19 (Coronavirus Disease 2019) pandemic, despite this, there were many complications in different health care facilities as well as dentists' clinics due to the lack of infection control knowledge and compliance failure. This study aimed to assess the level of knowledge and compliance with the infection control measures in the dental clinics in the Nablus and Tulkarm districts. RESULTS: The results showed that the total positive response regard all infection control domains were (70.0 %). Whereas the participants gave the highest positive response for personnel protective equipment i.e. gloving was (96.10 %). They gave the instruments related to controls the lowest responses, i.e. instruments sterilization was (59.40 %). The analyzed data showed significant statistical differences in the compliance with infection control measures between Nablus and Tulkarm districts "p < 0.05" in the interest of dentists from Tulkarm. CONCLUSIONS: In conclusion, the findings of this study showed that there is moderate compliance to infection control protocol in Nablus and Tulkarm dental clinics. Thus, there is a need to strengthen adherence to infection control measures. METHOD: A universal sampling was used to assess the infection control program at the dental clinics in Nablus and Tulkarm Districts. The study sample involved 265 dentists. Data was collected using a questionnaire which has been sent via email between July and August 2020. Descriptive statistics, Chi-square test, One-way ANOVA and Post-Hock tests have been used. Statistical significance was set at ″P <0.05″. Cronbach's alpha has been conducted to ensure the reliability and validity of the questionnaire.

The characteristics and availability of newer nonculture-based tests for identification of nosocomial fungal pathogens are discussed. Recently published recommendations and guidelines for the control and prevention of these nosocomial fungal infections are summarized.

Health Care-Acquired Viral Respiratory Diseases.

Health care-acquired viral respiratory infections are common and cause increased patient morbidity and mortality. Although the threat of viral respiratory infection has been underscored by the coronavirus disease 2019 (COVID-19) pandemic, respiratory viruses have a significant impact in health care settings even under normal circumstances. Studies report decreased nosocomial transmission when aggressive infection control measures are implemented, with more success noted when using a multicomponent approach. Influenza vaccination of health care personnel furthers decrease rates of transmission; thus, mandatory vaccination is becoming more common. This article discusses the epidemiology, transmission, and control of health care-associated respiratory viral infections.
