Abstract
Over the last three to four decades, Therapeutic Drug Monitoring (TDM) has shaped itself as therapeutic drug management, an integral component of precision medicine. The practice of TDM is not extensive in India, despite being one of the fastest-growing economies in the world. It is currently limited to a few academic medical centres and teaching hospitals. Apart from the immunosuppressive drugs, several other therapeutic areas, such as anticancer, antifungal, antibiotic and antitubercular, have demonstrated great potential to improve patient outcomes in Indian settings. Factors such as the higher prevalence of nutritional deficiencies, tropical diseases, widespread use of alternative medicines, unalike pharmacogenomics and sparse population-specific data available on therapeutic ranges of several drugs make the population of this subcontinent unique regarding the relevance of TDM. Despite the impact of TDM in clinical science and its widespread application, TDM has failed to receive the attention it deserves in India. This review intends to bring out a strength, weakness, opportunity and threats (SWOT) analysis for TDM in India so that appropriate steps for fostering the growth of TDM could be envisioned. The need of the hour is the creation of a cooperative group including all the stakeholders, such as TDM professionals, clinicians and the government and devising a National Action Plan to strengthen TDM. Nodal TDM centres should be established, and pilot programmes should be rolled out to identify the thrust areas for TDM in the country, capacity building and creating awareness to integrate TDM into mainstream clinical medicine.

Nosocomial infections in the surgical intensive care unit: an observational retrospective study from a large tertiary hospital in Palestine. BMC Infect Dis 2023; 23:686. [PMID: 37833675 PMCID: PMC10576355 DOI: 10.1186/s12879-023-08677-z] [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: 03/24/2023] [Accepted: 10/06/2023] [Indexed: 10/15/2023] Open
Abstract
BACKGROUND Nosocomial infections or hospital-acquired infections are a growing public health threat that increases patient morbidity and mortality. Patients at the highest risk are those in intensive care units. Therefore, our objective was to provide a pattern analysis of nosocomial infections that occurred in an adult surgical intensive care unit (ICU). METHODS This study was a retrospective observational study conducted in a 6-bed surgical intensive care unit (SICU) at An-Najah National University Hospital (NNUH) to detect the incidence of nosocomial infections from January 2020 until December 2021. The study group included 157 patients who received antibiotics during their stay in the SICU. RESULTS The incidence of nosocomial infections, either suspected or confirmed, in the SICU was 26.9% (95 out of 352 admitted patients). Pneumonia (36.8%) followed by skin and soft tissue infections (35.8%) were the most common causes. The most common causative microorganisms were in the following order: Pseudomonas aeruginosa (26.3%), Acinetobacter baumannii (25.3%), extended-spectrum beta lactamase (ESBL)-Escherichia coli (23.2%) and Klebsiella pneumonia (15.8%). The average hospital stay of patients with nosocomial infections in the SICU was 18.5 days. CONCLUSIONS The incidence of nosocomial infections is progressively increasing despite the current infection control measures, which accounts for an increased mortality rate among critically ill patients. The findings of this study may be beneficial in raising awareness to implement new strategies for the surveillance and prevention of hospital-acquired infections in Palestinian hospitals and health care centers.

Abstract
Background Carbapenem-resistant gram-negative bacteria (CRGNB) have become a public health concern worldwide. The risk factors associated with CRGNB infection after colonization are unknown, nor is the optimal timing of antibiotic treatment, warranting further investigation. Methods A 4-year single-center prospective observational study was conducted. CRGNB-colonized patients were incorporated on admission into our observation cohort for an active surveillance culture program, and analysis of risk factors associated with infections after CRGNB colonization was performed. We divided patients into empirical antibiotic therapy groups and standard antibiotic therapy groups according to whether antibiotics were used before or after cultures yielded a result to explore the relationship between the timing of antibiotics and clinical efficacy. Results 152 out of 451 CRGNB-colonized patients in the prospective observational cohort developed CRGNB infection. The risk factors associated with CRGNB infection after colonization included CRKP (P < 0.001, OR = 3.27) and CRPA (P < 0.001, OR = 2.97) colonization, history of carbapenems use (P < 0.001, OR = 5.48), and immunocompromise (P < 0.001, OR = 7.07). There were 88 infected patients in the empirical antibiotic therapy groups and 64 in standard antibiotic therapy groups. The mortality was lower in empirical therapy groups than standard therapy groups (17.0% vs. 37.5%, P = 0.004, OR = 0.32). Conclusions CRGNB colonized patients who are prone to infection have some high-risk factors included CRKP and CRPA colonization, immunocompromise, and prior carbapenems use. Once infection occurs in CRGNB-colonized patients, early use of effective antibiotics may be associated with reduced mortality, but more studies are needed.

Abstract
Hospital-acquired central line-associated bloodstream infections (CLABSIs) are the leading cause of infections in the pediatric intensive care unit. Bacteria responsible for CLABSIs are spread by health care workers, parents, and families and mitigated by scrupulous attention to hand hygiene and safety prevention strategies. Maintenance bundles are grouped elements, such as hand hygiene, standardized dressing and tubing changes, and aseptic technique for entering a central line, effective in preventing CLABSIs. Nurses can decrease the incidence of CLABSIs by using maintenance bundles and including parents and families in safety prevention strategies."

Abstract
PURPOSE To explore the clinical evidence available on mindful organizing (MO) that will improve teamwork for positioning and managing central venous catheters in patients admitted to neonatal intensive care and other pediatric intensive care units to decrease central-line-associated and catheter-related bloodstream infections (CLABSI and CRBSI). METHODS We searched several databases (PubMed, Embase, CINAHL, CENTRAL, SCOPUS, and Web of Science) up to June 2018. We included studies investigating the effectiveness of MO teamwork in reducing CLABSI and CRBSI. The systematic review followed the PRISMA guidelines. We used validated appraisal checklists to assess quality. RESULTS Seven studies were included: only one was a non-randomized case-controlled trial (CCT). All the others had a pre-post intervention design, one a time-series design and one an interrupted time-series design. The methodological heterogeneity precluded a meta-analysis. Despite the low certainty of evidence with the Grading of Recommendations Assessment, Development and Evaluation (GRADE) system, three studies including thousands of participants provided numerical data for calculating risk ratios (RR) and 95% confidence intervals (CI) comparing MO with no intervention for decreasing the CLABSI rate in neonatal and pediatric ICUs. The one CCT disclosed no significant difference in the CLABSI rate decrease between groups (RR = 0.96; 95%CI 0.47-1.97). Nor did the pre- and post-intervention interrupted time-series design disclose a significant decrease (RR = 0.80; 95%CI 0.36 1.77). In the study using a before-after study design, the GRADE system found that the CLABSI rate decrease differed significantly in favor of post-intervention (RR = 0.13; 95%CI 0.03 0.57; p = 0.007). CONCLUSIONS Despite the decreased CLABSI rate, the available evidence is low in quality. To reduce the unduly high CLABSI rates in neonatal and pediatric intensive care settings, custom-designed clinical trials should further define the clinical efficacy of MO to include it in care bundles as a new international standard.

Abstract
BACKGROUND Humans spend the bulk of their time in indoor environments. This space is shared with an indoor ecosystem of microorganisms, which are in continuous exchange with the human inhabitants. In the particular case of hospitals, the environmental microorganisms may influence patient recovery and outcome. An understanding of the bacterial community structure in the hospital environment is pivotal for the prevention of hospital-acquired infections and the dissemination of antibiotic resistance genes. In this study, we performed a longitudinal metagenetic approach in a newly opened ward at the Charité Hospital (Berlin) to characterize the dynamics of the bacterial colonization process in the hospital environment after first patient occupancy. RESULTS The sequencing data showed a site-specific taxonomic succession, which led to stable community structures after only a few weeks. This data was further supported by network analysis and beta-diversity metrics. Furthermore, the fast colonization process was characterized by a significant increase of the bacterial biomass and its alpha-diversity. The compositional dynamics could be linked to the exchange with the patient microbiota. Over a time course of 30 weeks, we did not detect a rise of pathogenic bacteria in the hospital environment, but a significant increase of antibiotic resistance determinants on the hospital floor. CONCLUSIONS The results presented in this study provide new insights into different aspects of the environmental microbiome in the clinical setting, and will help to adopt infection control strategies in hospitals and health care-related buildings.

Abstract
If wounds are infected with bacteria resistant to an empirical antibiotic regimen, effective wound treatment will be delayed. This can delay wound healing and lengthen hospital stays, increasing the costs to patients. Long-term antibiotic use can also result in minor and major complications, such as diarrhea, antibiotic resistance, or life-threatening leukopenia. Multidrug-resistant (MDR) bacteria make wound treatment even more difficult. Traditionally, surgeons thought that adequate infection control should be established before soft tissue coverage. However, wounds infected by MDR do not heal well with this traditional method and there are no optimal treatment guidelines for MDR bacteria-contaminated wounds.We reviewed 203 patients who underwent vascularized flap surgery from 2012 to 2019 to cover wounds. Class IV and I wounds were compared according to the Centers for Disease Control and Prevention classification. Class IV was further classified as antibiotic-resistant (ARB) and antibiotic-sensitive (ASB) bacteria. Wound size, mode, location, pathogens, healing time, and basic demographics were evaluated. Data were compared using Cramer's V and one-way ANOVA or independent t tests.The average healing time was longer in the ARB (19.7 [range 7-44] days) and ASB (17.9 [range 2-36] days) groups than in the Clean group (16.5 [range 7-28] days). Healing time differed in the 3 groups (P = .036). It was longer in the class IV group than in the class I group (P = .01). However, it was not statistically different between the ARB and ASB groups (P = .164).In our study the difference in healing time was small when vascularized tissue transfer was done in ARB-infected wound compared with ASB-infected and clean wound. It is necessary to perform surgery using vascularized tissue for the infected wound of antibiotic-resistant bacteria.

Abstract
PURPOSE OF REVIEW Given the extremely expensive nature of critical care medicine, it seems logical that intensivists should play an active role in designing efficient systems of care. The true value of intensivists, however, is not well defined. RECENT FINDINGS Anesthesiologists have taken key roles in improving patient safety in the operating room. Anesthesia-related mortality rates have decreased from 20 deaths per 100 000 anesthetics in the early 1980s to less than one death per 100 000 currently. Anesthesiologist-intensivists remain rare (less than 5% of certified anesthesiologists), but increasingly play multiple roles within multidisciplinary teams. This review outlines the roles of intensivists in performance improvement, perioperative assessment; sedation services, extracorporeal and mechanical support, and code/rapid response teams. Critical-care physicians, by definition, work in collaborative multispecialty and multidisciplinary teams that make it difficult to isolate each team member's precise contribution to healthcare value. SUMMARY Anesthesiologist-intensivists working outside their usual environment provide leadership and clinical guidance towards improving patient outcomes.

Abstract
OBJECTIVE Evidence-based guidelines have resulted in decreases in bloodstream infections associated with central catheters (CLABSIs) in hospital intensive care units. However, relatively little is known about CLABSI incidence and prevention in long-term acute care hospitals (LTACHs). METHODS A central catheter maintenance bundle was implemented in 30 LTACHs, and compliance with the bundle was tracked for 6 months. CLABSI rates were monitored for 14 months before and 14 months after the bundle was implemented. RESULTS The pooled mean CLABSI rate (No. of infections per 1000 days with a central catheter) was 1.28 before the bundle and 0.96 after the bundle (repeated measures general linear model; F1,58 = 6.973; P = .01; partial η(2) = .11). From 14 months before to 14 months after the bundle was implemented, the mean number of CLABSIs per LTACH decreased by 4.5 (95% CI, 1.85-7.15). Time series modeling showed a significant decrease in the mean hospital CLABSI rate after the bundle was implemented (-0.511 CLABSI/1000 catheter days, SE = 0.050), indicating an immediate effect of the bundle. The mean hospital CLABSI rate was decreasing slightly before the bundle was implemented and continued to decrease at a reduced rate after the bundle was implemented. CONCLUSION The bundle resulted in a significant and sustained reduction in CLABSI rates in 30 LTACHs for 14 months. These results encourage the development and implementation of similar bundles as effective strategies for infection reduction in LTACHs.

Central line-associated blood stream infections in pediatric intensive care units: Longitudinal trends and compliance with bundle strategies. Am J Infect Control 2015; 43:489-93. [PMID: 25952048 PMCID: PMC4430334 DOI: 10.1016/j.ajic.2015.01.006] [Citation(s) in RCA: 26] [Impact Index Per Article: 2.9] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/23/2014] [Revised: 01/06/2015] [Accepted: 01/07/2015] [Indexed: 11/26/2022]
Abstract
BACKGROUND Knowing the temporal trend central line-associated bloodstream infection (CLABSI) rates among U.S. pediatric intensive care units (PICUs), the current extent of central line bundle compliance, and the impact of compliance on rates is necessary to understand what has been accomplished and can be improved in CLABSI prevention. METHODS This is a longitudinal study of PICUs in National Healthcare Safety Network hospitals and a cross-sectional survey of directors and managers of infection prevention and control departments regarding PICU CLABSI prevention practices, including self-reported compliance with elements of central line bundles. Associations between 2011-2012 PICU CLABSI rates and infection prevention practices were examined. RESULTS Reported CLABSI rates decreased during the study period, from 5.8 per 1,000 line days in 2006 to 1.4 in 2011-2012 (P < .001). Although 73% of PICUs had policies for all central line prevention practices, only 35% of those with policies reported ≥95% compliance. PICUs with ≥95% compliance with central line infection prevention policies had lower reported CLABSI rates, but this association was statistically insignificant. CONCLUSION There was a nonsignificant trend in decreasing CLABSI rates as PICUs improved bundle policy compliance. Given that few PICUs reported full compliance with these policies, PICUs increasing their efforts to comply with these policies may help reduce CLABSI rates.

Abstract
BACKGROUND Preventing Ventilator-associated events (VAE) is a major challenge. Strictly monitoring for ventilator-associated pneumonia (VAP) is not sufficient to ensure positive outcomes. Therefore, the surveillance definition was updated and a change to the broader VAE was advocated. OBJECTIVE This paper summarizes the scientific efforts assessing VAP preventive bundles and the recent transition in surveillance methods. METHODS We conducted a systematic review to identify lessons from past clinical studies assessing VAP prevention bundles. We then performed a thorough literature review on the recent VAE surveillance algorithm, highlighting its advantages and limitations. CONCLUSION VAP prevention bundles have historically proven their efficacy and the introduction of the new VAE definition aimed at refining and objectivizing surveillance methods. Randomized controlled trials remain vital to determine the effect of VAE prevention on patient outcomes. We recommend expanding beyond limited VAP prevention strategies towards VAE prevention bundles.

Abstract
The worldwide emergence of epidemic strains of Clostridium difficile linked to increased disease severity and mortality has resulted in greater research efforts toward determining the virulence factors and pathogenesis mechanisms used by this organism to cause disease. C. difficile is an opportunist pathogen that employs many factors to infect and damage the host, often with devastating consequences. This review will focus on the role of the 2 major virulence factors, toxin A (TcdA) and toxin B (TcdB), as well as the role of other putative virulence factors, such as binary toxin, in C. difficile-mediated infection. Consideration is given to the importance of spores in both the initiation of disease and disease recurrence and also to the role that surface proteins play in host interactions.
