RESUMO

BACKGROUND: Ventilator-associated pneumonia (VAP) is the commonest healthcare-associated infection (HAI) in intensive care units (ICU), especially in trauma patients. VAP imposes a significant cost burden on the healthcare ecosystem. However, there are few data from the developing world. METHODOLOGY: We conducted this study in the trauma ICU (TICU) of PGIMER, Chandigarh, from October 2021 to December 2022. The incidence, incidence density, and average length of stay (ALOS) of both VAP and non-VAP patients were established. The health system cost was assessed using a mixed (top-down and bottom-up) micro-costing approach. We collected data for all the resources (direct and indirect costs) utilized during service delivery and estimated the health system cost per bed per day. RESULTS: In this study, 494 patients were admitted to TICU, of which 484 received Mechanical Ventilation (MV) and 47 developed VAP. We included 41 and 44 patients with and without VAP. The VAP incidence rate was 9.7% and the VAP incidence density was 10.79/1000 MV days. The ALOS for VAP patients was 21 days, and for non- VAP patients was 8.2 days. Our study estimated a total health system cost of INR 25,927 per bed per day. The health system cost of treating a VAP patient was INR 544,467 compared to INR 207,416 for a non-VAP patient. CONCLUSION: Treatment of VAP poses substantial costs for the health system and patients. There is a need to focus on preventing VAP, which would eventually reduce the length of stay and the resultant financial impact on the health system and the patient.

RESUMO

BACKGROUND: Respiratory physiotherapists (RPs) are an integral part of healthcare workers delivering care to intubated patients. Our study aimed to evaluate the effect of awareness campaigns on hand hygiene (HH) compliance among RPs. METHOD: An observational single-center study was conducted between 2015 and 2022 in different ICU types in both adult and paediatric settings. The hand hygiene compliance rates were monitored prospectively and the quality improvement interventions included various hand hygiene campaigns and awareness sessions with RPs. Compliance was calculated as a percentage of events over total opportunities observed. RESULTS: There was a significant increase in compliance rates for all five moments of HH (p-value: <0.05). Overall, mean compliance rate in ICUs was significantly higher than wards for Moment 1 (p-value: 0.0045), Moment 4 (p-value: 0.0372) and Moment 5 (p-value: 0.0036) by 24.2%, 22.7% and 21.5% respectively. Also, paediatric ICUs had higher HH compliance than adult ICUs for Moment 1 (87.5% vs 61.1%; p-value: 0.0459) and Moment 4 (93.7% vs 79.3%; p-value: 0.0255). A significant increase in HH compliance was observed in post-COVID-19 period compared to pre-COVID-19 period with respect to Moment 1, 2 and 5. CONCLUSION: This study adds to the almost non-existent literature on this important category of healthcare workers working in respiratory ICUs. Our results project an increase compliance after the HH awareness programmes over the years among RP which is critical to prevent spread infection by multidrug resistant organisms among the hospitals.

RESUMO

INTRODUCTION: The current systematic review aimed to collect and analyze the comprehensive evidence regarding Polymerase Spiral Reaction (PSR) and to estimate its diagnostic performance and usefulness as a point-of-care (PoC) assay. METHODS: Literature was retrieved systematically from 2015 to 2023 from PubMed and Scopus. Studies were screened and selected against pre-determined inclusion and exclusion criteria. Quality assessment and risk of bias were critiqued using QUADAS-2. A systematic, qualitative narrative synthesis was employed to synthesize the data. RESULTS: 11 studies were selected for the systematic review, testing diseases in humans utilizing PSR. Only 2 studies clinically validated the test with a sample size > 150. 5 studies were of poor quality; 3 studies were of moderate quality and 3 studies were deemed to be of high quality. 3 studies quantified the diagnostic throughput and reported clinical sensitivity and specificity of PSR approaching to be > 92% and ~ 100%, respectively. CONCLUSION: Polymerase spiral reaction promises to be an optimistic isothermal assay; however, a huge research gap can be attributed to the lack of statistical and clinical evidence to validate the assay. Adequate research, focused on optimization, coupled with statistical and clinical validation, can help in estimating its true diagnostic potential and applicability. REGISTRATION AND PROTOCOL: A detailed protocol of this review is registered and available in Prospero (registration number CRD42023406265).

RESUMO

BACKGROUND: The maintenance bundle of care for all venous access devices (peripheral intravenous catheters, PIVC; central venous catheters, CVCs; hemodialysis ports) is important to prevent secondary sepsis in critically ill patients. This quality improvement project analyzed the effect of intensive training and education of health care workers (HCWs) on maintenance bundles for venous access devices. METHODS: The study period comprising of preintervention phase (3-months) included 25 random visits to the intensive care unit for point observations regarding maintenance of all venous access devices in-situ in all intensive care unit patients on the day of the visit. The observations were categorized as appropriate or inappropriate practices based on American Society of Anesthesiologists (ASA) guidelines for CVC 2020, INICC guidelines for PIVC 2017, and Australian Commission on Safety and Quality in Health Care (ACQHCS) for PIVC and hemodialysis ports, December 2019. While the intervention phase (1-month) comprised intensive training and education of HCWs, postintervention phase 3 (3-months) included similar visits and point observations as during the preintervention phase. RESULTS: The maintenance of PIVC improved significantly in terms of the condition of site (from 82.7% appropriate observations to 97.8%, P < .05); condition of connectors (45.7%-56.8%, P < .05), and any attached unused IV sets (90.5%-98.56%, P < .05). For CVC, there was significant improvement in condition of insertion site (66%-94%, P < .01); condition of connectors (0%-44.37%, P < .01); fixation (91%-99.3%, P < .05); any attached unused IV sets (38.9%-97.3%, P < .01) and knowledge of HCW (96.52%-100%, P = .05). For hemodialysis ports, no significant improvement was observed. CONCLUSIONS: Intensive training and education of HCWs led to significant improvement in the maintenance bundle of care for PIVC and CVC.

RESUMO

Scrub typhus infection is reemerging leading cause of acute febrile illnesses in post-rainy or monsoon season in Southeast Asia. It is caused by Orientia tsutsugamushi and spread by the bite of chiggers, larval forms of trombiculid mites. The clinical picture can range from simple acute febrile illness to multiorgan dysfunction. Neurological manifestations also vary from aseptic meningitis, meningoencephalitis, cerebral infarction, acute disseminated encephalomyelitis, transverse myelitis, and psychiatric manifestations. Here, we present a case series of eight cases of scrub meningoencephalitis diagnosed based on clinical, laboratory, and radiological criteria.

RESUMO

Scrub typhus is a zoonotic disease caused by Orientia tsutsugamushi. Although the presence of eschar is considered pathognomic, diagnosis of scrub typhus is challenging due to overlapping presentation. The diagnosis is based on the serological and molecular assay. Here, we describe a case of a young male patient who was diagnosed with scrub typhus and developed complications in the course of the disease. We also performed molecular characterization of the strain which revealed a close relatedness to Karp-like Linh.DT strains were previously reported from Vietnam.

RESUMO

BACKGROUND: Detection of infectious diseases, especially among immunocompromised and patients on prolonged anti-microbial treatment, remains challenging, limited by conventional techniques with low sensitivity and long-turnaround time. Molecular detection by polymerase chain reaction (PCR) also has limited utility as it requires a targeted approach with prior suspicion of the infecting organism. Advancements in sequencing methodologies, specifically next-generation sequencing (NGS), have presented a promising opportunity to identify pathogens in cases where conventional techniques may be inadequate. However, the direct application of these techniques for diagnosing invasive infections is still limited by the need for invasive sampling, highlighting the pressing need to develop and implement non-invasive or minimally invasive approaches to improve the diagnosis of invasive infections. OBJECTIVES: The objectives of this article are to explore the notable features, clinical utility, and constraints associated with the detection of microbial circulating cell-free DNA (mcfDNA) as a minimally invasive diagnostic tool for infectious diseases. CONTENT: The mcfDNA detection provides an opportunity to identify micro-organisms in the blood of a patient. It is especially beneficial in immunocompromised patients where invasive sampling is not possible or where repeated cultures are negative. This review will discuss the applications and constraints of detecting mcfDNA for diagnosing infections and the various platforms available for its detection.

RESUMO

Introduction: Acute encephalitis syndrome (AES) or acute febrile encephalopathy is a clinical condition characterized by altered mental status occurring after or along with a short febrile illness. In developing countries, infections are the predominant cause of AES. Prominent infections known to cause AES include viruses (such as herpes simplex virus [HSV], Japanese Encephalitis [JE] virus, dengue, enteroviruses [EVs]), bacteria, fungus, and parasites. In the present study, we aim to analyze the etiology, clinical features, and predictors of mortality in patients presenting with acute febrile encephalopathy or acute encephalitic syndrome. The present study was a prospective observational study conducted at Post Graduate Institute of Medical Education and Research a tertiary care center in Chandigarh, India. Methods: A total of 105 patients with ≥18 years of age with fever (body temperature >101° F for duration ≤14 days) and altered sensorium (Glasgow coma scale [GCS] score ≤10) lasting for more than 24 h, either accompanying the fever or following it were enrolled. Demographic and clinical details were recorded on pro forma. Cerebrospinal fluid (CSF) analysis was performed for all the enrolled patients at admission for cytology, CSF glucose to blood glucose ratio, protein levels, gram stain and culture sensitivity, adenosine deaminase levels, polymerase chain reaction for HSV/EV/mycobacterium tuberculosis (TB) and immunoglobulin M Enzyme-linked immune assay for JE. Computed tomography of the brain was done in all patients while magnetic resonance imaging (MRI) of the brain was carried out in 75 patients. Results: Among the 105 patients, tubercular meningitis was seen in 27 (25.7%) patients followed by acute pyogenic meningitis in 18 (17.1%) patients. Probable viral encephalitis was present in 12 (11.4%) cases. Septic encephalopathy (n = 10) and scrub typhus encephalitis (n = 8), HSV encephalitis (n = 6), dengue encephalitis (n = 4), leptospirosis (n = 3) were the other infections causing acute febrile encephalitis in our study. In addition to fever and altered sensorium common symptoms observed were headache (52.4%), vomiting (35.2%), and seizures (29.5%). The factors predicting increased mortality were female gender, fever of more than 38°C at admission, GCS <7, MRI showing disease-related findings like altered signal intensity bilateral medial temporal and insular area in herpes simplex encephalitis, etc., changes, and the group of patients where a definite diagnosis could not be established during the hospital stay. Conclusions: Tubercular meningitis/central nervous system TB is the predominant cause of acute febrile encephalopathy in developing countries. Scrub and dengue encephalitis are emerging as an important cause of acute febrile encephalopathy and occur predominantly in postmonsoon seasons. Acute febrile encephalopathy remains an important cause of mortality in patients presenting to Emergency Department (ER). The strongest predictors of mortality are low GCS and undiagnosed cases of AES.

RESUMO

BACKGROUND: Changing climatic conditions and invasion of ticks in urban areas have led to a greater number of cases of tick-borne diseases, thus, becoming a matter of increasing concern. Tick borne rickettsioses are one of the important emerging diseases worldwide. Knowledge of epidemiology of the vector and pathogen in the community is essential in order to understand and prevent the transmission of the disease to healthy population. METHODS: In our present study, we trapped rodents in selected areas of Chandigarh and Punjab in north India. The rodents were screened for the presence of ticks which were further screened for the presence of rickettsial agents. PCRs targeting 17 â€‹kDa and gltA genes were carried out followed by Sanger sequencing of the positive amplicons followed by phylogenetic analysis of the sequences. RESULTS: A total of 17 ticks were collected out of which one (Rhipicephalus sanguineus) was found to be harboring a Rickettsia sp. PCR targeting gltA and 17 â€‹kDa genes of rickettsia were put up and Sanger sequencing was performed. Phylogenetic analysis revealed the sequences to be closely related to Rickettsia rhipicephali. CONCLUSION: The current study establishes the presence of rickettsial agents in the community. Although Rickettsia rhipicephali is a non-pathogenic agent, the study encourages more vigorous community surveillance should be carried out in order to determine the exact burden of rickettsial agents in our community. To our knowledge, this is the first study reporting Rickettsia rhipicephali in India.

RESUMO

Background & Aims: The reported burden of multidrug-resistant organism (MDRO) infections is highest in patients with cirrhosis from India. We evaluated whether colonisation at multiple barriers predisposes to such infections and poor outcomes in patients with cirrhosis. Methods: We prospectively performed swab cultures, antimicrobial susceptibility testing (AST), and genotype testing for MDROs from various sites (rectum, nose, composite-skin, and central-line) in patients with cirrhosis (2020-2021) on admission and follow-up at a tertiary institute. We analysed clinical data, risk factors for MDROs, and patient outcomes. Results: Of 125 patients aged 49 years, 85.6% males, 60.8% with acute-on-chronic liver failure, 99 (79.2%) were identified as 'colonisers'. MDRO-colonisation at rectum, nose, skin, or central line was observed in 72.7% (88/121), 30.0% (36/120), 14.9% (18/121), and 3.3% (4/121) patients, respectively. Patients were colonised with the following types of bacteria: extended-spectrum beta-lactamase (71/125), carbapenem-resistant Enterobacterales (67/125), MDR-Enterococcus (48/125), MDR-Acinetobacter (21/125), or methicillin-resistant Staphylococcus aureus (4/125). Multiple precipitants of acute-decompensation (odds ratio [OR]: 3.4, p = 0.042), norfloxacin prophylaxis (OR: 3.9, p = 0.008), and MDRO infection at admission (OR: 8.9, p = 0.041) were the independent predictors of colonisation. Colonisation increased the risk of infection by MDROs at admission (OR: 8.5, p = 0.017) and follow up (OR: 7.5, p <0.001). Although any-site colonisers were at greater risk of cerebral failure and poorer Child-Pugh scores, the nasal and skin colonisers were at higher risk of cerebral and circulatory failures than non-colonisers (p <0.05).Patients with more than one site colonisation (prevalence: 30%) developed multi-organ failure (p <0.05), MDRO infection (OR: 7.9, p <0.001), and poorer 30-day survival (hazard ratio: 2.0, p = 0.005). Conclusions: A strikingly high burden of MDRO colonisation among patients with cirrhosis in India necessitates urgent control measures. Multiple-site colonisation increases the risk of MDR-infections, multi-organ failure, and mortality in patients with cirrhosis. Impact and Implications: Infections by bacteria resistant to multiple antibiotics are an emerging cause of death in cirrhosis. We showed that ∼70-80% of critically ill hospitalised patients with cirrhosis carry such bacteria with the highest rate in the rectum, nose, skin, and central line port. Carbapenem-resistant and vancomycin-resistant bacteria were amongst the most common colonising bacteria. The presence of these bacteria at multiple sites increased the risk of multidrug-resistant infections, multiple organ failures, and death in patients with cirrhosis.

RESUMO

The utility of surveillance stool culture (SSC) to guide antibiotics for febrile neutropenia (FN) is unresolved in non-transplant settings. The prospective study explored the prevalence of multidrug-resistant organisms (MDRO) in SSCs, its correlation with mortality, and the concordance of SSCs with cultures obtained during subsequent episodes of FN amongst children with acute leukemia. SSCs were obtained at presentation and 2 mo into chemotherapy. Seventy-nine patients (mean age: 5.9±3.2 y) with acute lymphoblastic leukemia (ALL) (80%), acute myeloid leukemia (AML) (16%), or biphenotypic leukemia (4%) were enrolled. MDROs were isolated from 14 (17.5%) patients in the first SSCs, including E.coli (80%), K. pneumoniae (10%), and E. faecium (10%). Three (3.8%) patients developed MDRO sepsis; none concorded with the SSCs. Eleven (14%) patients died; 4/14 (28.5%) with MDRO-colonization vis-à-vis 7/66 (10.6%) without MDRO-colonization (OR: 3.37, 95% CI: 0.8-13.6; p = 0.095). MDRO-colonization failed to predict MDRO-sepsis, bloodstream infection, or mortality. SSC failed to guide the choice of antibiotics for FN in children with acute leukemia.

RESUMO

Rickettsial diseases (RD) are widely reported all over the world. Scrub typhus (ST) is a major tropical infection which is well documented all over India. Therefore, the index of suspicion of scrub typhus is high among physicians with regard to patients presenting with acute febrile illness (AFI) and acute undifferentiated febrile illness (AUFI) in India. Rickettsial diseases other than ST (non-ST RDs), which include spotted fever group (SFG) rickettsioses and typhus group (TG) rickettsioses are not uncommon in India, but the index of suspicion is not as high as ST unless there is a history of the presence of fever with rashes and/or recent arthropod bites. This review aims to look into the Indian scenario on the epidemiology of non-ST RDs, especially the SFG and TG rickettsioses based on various investigations, spectrum of clinical presentation, challenges and gaps in knowledge to suspect and diagnose these infections.

RESUMO

Introduction In the ongoing severe acute respiratory syndrome coronavirus 2 pandemic, a long hospital stay and empirical broad-spectrum antibiotics make the patients prone to acquire nosocomial infections especially with unconventional organisms, and Chryseobacterium gleum is one such rare nosocomial pathogen. Methods The given study is a case-series-based study conducted from September 2020 to April 2021 in which clinically suspected pneumonia patients who recovered from coronavirus disease 2019 (COVID-19) were included. Results Seventeen C. gleum isolates were obtained in pure culture from the tracheal aspirates of nine COVID-19 patients (including repeat samples to rule out colonization) within a period of eight months (September 2020-April 2021). Our records showed that there has been an increase in the number of isolates of C. gleum obtained in respiratory samples in 2020. We also did a review of literature of all the cases of C. gleum pneumonia reported till now. Conclusion To the best of our knowledge, this is the first study reporting the isolation of this rare pathogen from COVID-19 patients with clinical significance in a large cohort of patients. Therefore, it becomes important to consider this pathogen as a significant cause of respiratory infections, especially in patients recovered post COVID-19.

RESUMO

Rickettsial infections are an important cause of acute febrile illness in developing countries. They can rarely present with cutaneous manifestations such as gangrene. Here we report a 12-year-old boy who presented with acute undifferentiated fever, multiorgan dysfunction, and gangrene of bilateral toes and ear lobes. The diagnosis was made by serologic testing of paired sera and clinical recovery occurred with doxycycline.

RESUMO

Background Considering the virulent nature of the COVID-19, the safety of healthcare workers (HCW) became a challenge for hospital administrators. Wearing a personal protective equipment (PPE) kit, called donning, which can be easily done by the help of another staff. But correctly removing the infectious PPE kit (doffing) was a challenge. The increased number of HCWs for COVID-19 patient care raised the opportunity to develop an innovative method for the smooth doffing of PPEs. Objective We aimed to design and establish an innovative PPE doffing corridor in a tertiary care COVID-19 hospital during the pandemic in India with a heavy doffing rate and minimize the COVID-19 virus spread among healthcare workers. Methodology A prospective, observational cohort study at the COVID-19 hospital, Postgraduate Institute of Medical Education and Research (PGIMER), Chandigarh, India, was conducted from July 19, 2020, to March 30, 2021. The time taken for PPE doffing process of HCWs was observed and compared between the doffing room and doffing corridor. The data was collected by a public health nursing officer using Epicollect5 mobile software and Google forms. The following parameters, like grade of satisfaction, time and volume of doffing, the errors in the steps of doffing, rate of infection, were compared between the doffing corridor and the doffing room. The statistical analysis was done by the use of SPSS software. Result 'Doffing corridor' decreased the overall doffing time by 50% compared to the initial doffing room. The doffing corridor solved the purpose of accommodating more HCWs for PPE doffing and an overall saving of 50% time. Fifty-one percent of HCWs rated the satisfaction rate as Good in the grading scale. The errors in the steps of doffing that occurred in the doffing process were comparatively lesser in the doffing corridor. The HCWs who doffed in the doffing corridor were three times less likely to get self-infection than the conventional doffing room. Conclusion Since COVID-19 was a new pandemic, the healthcare organizations focused on innovations to combat the spread of virus. One of these was an innovative doffing corridor to expedite the doffing process and decrease the exposure time to the contaminated items. The doffing corridor process can be considered at a high-interest rate to any hospital dealing with infectious disease, with high working satisfaction, less exposure to the contagion, and less risk of infection.

RESUMO

BACKGROUND: The appropriate antibiotic treatment for severe scrub typhus, a neglected but widespread reemerging zoonotic infection, is unclear. METHODS: In this multicenter, double-blind, randomized, controlled trial, we compared the efficacy of intravenous doxycycline, azithromycin, or a combination of both in treating severe scrub typhus. Patients who were 15 years of age or older with severe scrub typhus with at least one organ involvement were enrolled. The patients were assigned to receive a 7-day course of intravenous doxycycline, azithromycin, or both (combination therapy). The primary outcome was a composite of death from any cause at day 28, persistent complications at day 7, and persistent fever at day 5. RESULTS: Among 794 patients (median age, 48 years) who were included in the modified intention-to-treat analysis, complications included those that were respiratory (in 62%), hepatic (in 54%), cardiovascular (in 42%), renal (in 30%), and neurologic (in 20%). The use of combination therapy resulted in a lower incidence of the composite primary outcome than the use of doxycycline (33% and 47%, respectively), for a risk difference of -13.3 percentage points (95% confidence interval [CI], -21.6 to -5.1; P = 0.002). The incidence with combination therapy was also lower than that with azithromycin (48%), for a risk difference of -14.8 percentage points (95% CI, -23.1 to -6.5; P<0.001). No significant difference was seen between the azithromycin and doxycycline groups (risk difference, 1.5 percentage points; 95% CI, -7.0 to 10.0; P = 0.73). The results in the per-protocol analysis were similar to those in the primary analysis. Adverse events and 28-day mortality were similar in the three groups. CONCLUSIONS: Combination therapy with intravenous doxycycline and azithromycin was a better therapeutic option for the treatment of severe scrub typhus than monotherapy with either drug alone.

RESUMO

BACKGROUND: Emphysematous osteomyelitis (EO) is an extremely rare form of osteomyelitis which is complicated mainly by infection with gas-forming organisms. The common causative agents of this disease are mainly members of Enterobacteriaceae family, the most common are Escherichia coli and Klebsiella pneumoniae along with anaerobes. A total of 48 cases of EO have been reported in the literature till now globally and none have documented the isolation of Corynebacterium amycolatum. CASE PRESENTATION: We report a rare case of emphysematous osteomyelitis of the spine and pelvis due to Escherichia coli along with the isolation of Corynebacterium amycolatum from the same pus samples on two consecutive occasions in a 50-year-old female with uncontrolled diabetes mellitus, who was successively treated with antibiotics and drainage of pus. We also did a brief review of the literature of all cases reported till now. CONCLUSION: The role of Corynebacterium amycolatum in the etiology of emphysematous osteomyelitis needs to be evaluated further in future studies as we cannot completely ignore its isolation in two consecutive samples as a mere contaminant.

RESUMO

BACKGROUND: Healthcare-associated infections (HAIs) are one of the most common adverse events in patient care that account for substantial morbidity and mortality. We evaluate the existing Infection Prevention and Control (IPC) practices in hospitals participating in the nationally representative HAI Surveillance network. METHODS: This cross-sectional survey was conducted in 23 hospitals across 22 states of India from October-2015 to September-2018 in the HAI surveillance network. The World Health Organization (WHO) IPC core components assessment tool for health-care facility level (IPCAT-H) was adapted from IPC assessment tool developed by US Centers for Disease Control and Prevention (US CDC) under the Epidemiology and Laboratory Capacity (ELC) Infection Control Assessment and Response (ICAR) Program. Mann-Whitney U test was used to calculate the significant difference between scores (P < .05). RESULTS: Amongst the participating hospitals, 7 were private sectors and 16 were public health care facilities. Infection IPCAT-H average score per multimodal strategy was less than 50% for programmed IPC activities (45.7); implementation of health care workers (HCWs) immunization programme (43.5%); monitoring and evaluation component (38.30%). CONCLUSIONS: There is potential for improvement in Human Resources, Surveillance of HAIs as well as Monitoring and Evaluation components.
