Characterization of the Benefits and Risks of Therapeutic Anticoagulation in Patients Admitted with Severe COVID-19 (CRITAC).

Severe COVID-19 is associated with increased rates of thrombotic complications. Recent provincial recommendations in British Columbia have suggested providing thromboprophylaxis with therapeutic anticoagulation for hospital inpatients with severe COVID-19 who do not have a high risk of bleeding. To characterize the rates of major bleeding, thrombotic events, complications from COVID-19, and adverse effects among patients with severe COVID-19 treated with therapeutic anticoagulation. This retrospective chart review involved patients with laboratory-confirmed COVID-19 who were admitted to 3 sites within a local health authority between April 1 and December 31, 2021, and received therapeutic anticoagulation for thromboprophylaxis. After screening of 1036 patients, 72 patients were included in the study. The mean age of participants was 54 years, 63% (n = 45) were male, and 92% (n = 66) were receiving supplemental oxygen by nasal prongs on admission. The primary outcome, major bleeding, was experienced by 1 patient (1%). Increasing oxygen requirements resulting in progression to high-flow nasal cannula occurred in 11 patients (15%), and 5 patients (7%) required admission to the intensive care unit. One patient (1%) experienced a thrombotic event, and 1 patient (1%) had a minor bleed. The mean duration of hospitalization was 10 (standard deviation 10.8) days. One death occurred during the study period, and no cases of heparin-induced thrombocytopenia were observed. In this study of hospital inpatients with severe COVID-19 who were deemed to be at low risk of bleeding and who received therapeutic anticoagulation, there were low rates of both major bleeding and thrombotic events.

Hospital Management Practice of Combined Prediction Method Based on Neural Network

In this article, the outpatient volume, hospitalization income and drug demand in hospital management are taken as the research objects, and a neural network combined prediction model is established to predict the outpatient volume with the fitting prediction results of cubic polynomial regression model and grey model as the input of the network and the actual statistical outpatient volume as the output. Lasso variable selection method is used to determine the main indexes affecting the income of inpatients in hospital, and a prediction model combining grey prediction and artificial neural network is established to predict the income of inpatients in hospital. By studying the key characteristics of hospital drug demand, BP neural network, RBF neural network and GRNN generalized regression neural network are selected to predict the drug demand. By solving the quadratic programming problem and according to the weight rules, a combination forecasting model based on neural network is established to predict the drug demand, and the accuracy and stability of the model are evaluated.

PERINEAL PAIN AND DISCOMFORT: A STRANGE PHENOMENON FOLLOWING INTRAVENOUS DEXAMETHASONE

Objectives: The objectives of this study were to estimate the incidence of perineal discomfort, to assess the type of perineal discomfort, and to determine the time frame in which the discomfort started and persisted following IV administration of Dexamethasone in patients in the wards of a tertiary care teaching hospital. Methods: This study was a descriptive cross-sectional study among 235 inpatients of a tertiary care hospital in Kerala receiving IV Dexamethasone. Study setting was in-patient wards of Government Medical College, Manjeri, Kerala. The study duration was 6 months from the date of IEC approval. Results: Out of the 235 patients enrolled to the study, 126 (55.6%) were male and 109 (44.4%) were female. The mean age of the patients enrolled was 55.85±16.657. About 63 (26.8%) patients developed abnormal discomfort or symptoms following IV Dexamethasone injection. Patients presented the symptoms mainly over perineal area, perianal area, and lower abdomen. About 50 (79.4%) presented with symptoms in perineal area. All the 63 (100%) patients who experienced the symptoms had sudden and spontaneous onset of symptoms while administering the injection and the duration of the symptoms varied from few seconds to 5 min. There was no significant relationship between gender and dosage with appearance of symptoms. Conclusion: In clinical practice, health-care professionals should be aware of such transient symptoms of perineal irritation and pruritus followed by IV Dexamethasone. Even though the exact mechanism is not known, this should be kept in mind and proper dilution and slow administration of the dexamethasone should be done to reduce such symptoms.

County medical community, medical insurance package payment, and hierarchical diagnosis and treatment-Empirical analysis of the impact of the pilot project of compact county medical communities in Sichuan Province.

Hierarchical diagnosis and treatment (HDT) is an important exploration direction to alleviate the rising pressure of health expenses and medical insurance fund expenditure in China, and to maintain and protect the public health in this country. In recent years, the construction of compact county medical communities (CCMC) has become the primary approach for implementing the HDT. Utilizing the quasi-natural experiment of the pilot project of CCMC in Sichuan Province in 2019, coupled with county-level data extracted from the ' Sichuan Provincial Health Statistics Yearbook ' spanning the years 2008 to 2021, this research evaluates the effect of the pilot project of CCMC on promoting HDT under the medical insurance package payment model. The results show that the pilot project of CCMC has significantly increased the number of consultations per capita of medical and health institutions in pilot counties by 0.434 times, of which the number of consultations per capita of primary medical institutions has increased by 0.340 times; the number of hospitalizations per capita in public hospitals and primary medical institutions in pilot counties increased significantly, and the surgery rate of inpatients in public hospitals increased by 5% compared to before the pilot. There was no significant impact on the allocation of medical facilities and human resources in the pilot counties. Therefore, the construction of CCMC under the medical insurance package payment mode has promoted the realization of the county-level HDT. These findings provide valuable insights for healthcare policy, especially in developing and implementing effective strategies for HDT in county-level medical institutions.

Objective and subjective sleep characteristics in hospitalized older adults and their associations to hospital outcomes

PurposeSleep in the hospital setting is understudied, with limited literature describing measurement of sleep quality. This study among older inpatients in an acute-care hospital describes sleep characteristics both objectively and subjectively, and explores the associations of sleep with hospital outcomes.Materials and methodsOlder patients (n = 112) at Sutter Tracy Community Hospital were enrolled from January 2016 to November 2017. Sleep prior to admission was measured subjectively [Pittsburgh Sleep Quality Index (PSQI)], while sleep during hospitalization was measured subjectively (sleep diaries) and objectively (actigraphy, averaged over all nights). Outcomes measured included change in cognition during the hospital stay (i.e., Montreal Cognitive Assessment), length of stay (LOS), discharge to a skilled nursing facility (SNF), and re-admittance to a hospital within 30 days of discharge.ResultsThe participants were on average 68.7 ± 6.5 years old, predominately white (77%) and 55% women. Average PSQI was high (9.1 ± 4.2) indicating poor sleep quality prior to admission. Actigraphy was well-tolerated, with most (89%) having complete data. Sleep during the hospital stay was disturbed, with low levels of total sleep time (5.6 ± 2.0 h) and high levels of fragmentation (sleep efficiency 68.4 ± 15.0%). Sleep interruption was reported on 71% of sleep diaries, with the most common reasons being due to medical care [measurement of vitals (23%), staff interruptions (22%), blood draws (21%)]. Those with lower sleep efficiency had more cognitive decline upon discharge. Although underpowered, there was a suggestion of an association with poor sleep and the likelihood of being discharged to a SNF. Those with worse self-reported sleep quality (PSQI) prior to admission had a slightly longer LOS. No associations were seen with sleep quality and likelihood of readmission.ConclusionsCollection of objective and subjective sleep measures was feasible among hospitalized older adults. Disrupted sleep was common, and was potentially related to poor hospital outcomes. Our next steps will be to leverage these results to design and implement an intervention to improve sleep in hospitalized adults.

Quantitative Assessment of Fundus Tessellated Density in Highly Myopic Glaucoma Using Deep Learning.

To characterize the fundus tessellated density (FTD) in highly myopic glaucoma (HMG) and high myopia (HM) for discovering early signs and diagnostic markers. This retrospective cross-sectional study included hospital in-patients with HM (133 eyes) and HMG (73 eyes) with an axial length ≥26 mm at Zhongshan Ophthalmic Center. Using deep learning, FTD was quantified as the average exposed choroid area per unit area on fundus photographs in the global, macular, and disc regions. FTD-associated factors were assessed using partial correlation. Diagnostic efficacy was analyzed using the area under the curve (AUC). HMG patients had lower global (0.20 ± 0.12 versus 0.36 ± 0.09) and macular FTD (0.25 ± 0.14 vs. 0.40 ± 0.09) but larger disc FTD (0.24 ± 0.11 vs. 0.19 ± 0.07) than HM patients in the tessellated fundus (all P < 0.001). In the macular region, nasal FTD was lowest in the HM (0.26 ± 0.13) but highest in the HMG (0.32 ± 0.13) compared with the superior, inferior, and temporal subregions (all P < 0.05). A fundus with a macular region nasal/temporal (NT) FTD ratio > 0.96 (AUC = 0.909) was 15.7 times more indicative of HMG than HM. A higher macular region NT ratio with a lower horizontal parapapillary atrophy/disc ratio indicated a higher possibility of HMG than HM (AUC = 0.932). FTD differs in degree and distribution between HMG and HM. A higher macular NT alone or with a lower horizontal parapapillary atrophy/disc ratio may help differentiate HMG. Deep learning-based FTD measurement could potentially assist glaucoma diagnosis in HM.

Evaluation of venous thromboembolism risk assessment models for hospital inpatients: the VTEAM evidence synthesis.

Pharmacological prophylaxis during hospital admission can reduce the risk of acquired blood clots (venous thromboembolism) but may cause complications, such as bleeding. Using a risk assessment model to predict the risk of blood clots could facilitate selection of patients for prophylaxis and optimise the balance of benefits, risks and costs. We aimed to identify validated risk assessment models and estimate their prognostic accuracy, evaluate the cost-effectiveness of different strategies for selecting hospitalised patients for prophylaxis, assess the feasibility of using efficient research methods and estimate key parameters for future research. We undertook a systematic review, decision-analytic modelling and observational cohort study conducted in accordance with Enhancing the QUAlity and Transparency Of health Research (EQUATOR) guidelines. NHS hospitals, with primary data collection at four sites. Medical and surgical hospital inpatients, excluding paediatric, critical care and pregnancy-related admissions. Prophylaxis for all patients, none and according to selected risk assessment models. Model accuracy for predicting blood clots, lifetime costs and quality-adjusted life-years associated with alternative strategies, accuracy of efficient methods for identifying key outcomes and proportion of inpatients recommended prophylaxis using different models. We identified 24 validated risk assessment models, but low-quality heterogeneous data suggested weak accuracy for prediction of blood clots and generally high risk of bias in all studies. Decision-analytic modelling showed that pharmacological prophylaxis for all eligible is generally more cost-effective than model-based strategies for both medical and surgical inpatients, when valuing a quality-adjusted life-year at £20,000. The findings were more sensitive to uncertainties in the surgical population; strategies using risk assessment models were more cost-effective if the model was assumed to have a very high sensitivity, or the long-term risks of post-thrombotic complications were lower. Efficient methods using routine data did not accurately identify blood clots or bleeding events and several pre-specified feasibility criteria were not met. Theoretical prophylaxis rates across an inpatient cohort based on existing risk assessment models ranged from 13% to 91%. Existing studies may underestimate the accuracy of risk assessment models, leading to underestimation of their cost-effectiveness. The cost-effectiveness findings do not apply to patients with an increased risk of bleeding. Mechanical thromboprophylaxis options were excluded from the modelling. Primary data collection was predominately retrospective, risking case ascertainment bias. Thromboprophylaxis for all patients appears to be generally more cost-effective than using a risk assessment model, in hospitalised patients at low risk of bleeding. To be cost-effective, any risk assessment model would need to be highly sensitive. Current evidence on risk assessment models is at high risk of bias and our findings should be interpreted in this context. We were unable to demonstrate the feasibility of using efficient methods to accurately detect relevant outcomes for future research. Further research should evaluate routine prophylaxis strategies for all eligible hospitalised patients. Models that could accurately identify individuals at very low risk of blood clots (who could discontinue prophylaxis) warrant further evaluation.

A prediction model for reactivation of Langerhans cell histiocytosis based on machine-learning algorithms.

Langerhans cell histiocytosis (LCH) is a rare inflammatory myeloid neoplasm characterized by the clonal proliferation of myeloid progenitor cells. The reactivation rate of LCH exceeds 30%. However, an effective prediction model to predict reactivation is lacking. To select potential prognostic factors of LCH and construct an easy-to-use predictive model based on machine-learning algorithms. Clinical records of LCH inpatients in the Second Xiangya Hospital of Central South University, from 2008 to 2022, were retrospectively studied. Seventy-six patients were classified into a reactivated/progressive group or a stable group. Clinical features and laboratory outcomes were compared, and machine-learning algorithms were used for building prognostic prediction models. Clinical classification (single-system LCH, multiple-system LCH, and central nervous system/lung LCH), level of anemia, bone involvement, skin involvement, and elevated monocyte count were the best performing factors and were finally chosen for the construction of the prediction models. Our results show that the above-mentioned five factors can be used together in a prediction model for the prognosis of LCH patients. The major limitations of this study include its retrospective nature and the relatively small sample size.

A Study on Etiology, Risk Factors, and Clinical Profile of Spontaneous Pneumothorax: A Single-Center Experience from South India

Abstract Introduction: Spontaneous pneumothorax (SP) commonly presents as continuous, sharp, unilateral chest pain exacerbated by deep inspiration and change of posture. The present study has been undertaken to study the clinical profile of SP among in-patients of a tertiary care hospital in South India. Methodology: A prospective hospital-based study of 100 consecutive cases diagnosed with SP from January 2019 to September 2020. Every patient underwent comprehensive history taking, in-depth clinical examination, and investigations. Data were entered into Excel spreadsheets in 2019. Data were presented using frequency and percentage and descriptive statistics were used. Results: SP was more common in males, Smoking can be considered a significant risk factor for SP, as 54% of all cases had a history of smoking. Dyspnea, accompanied by unilateral chest pain is the most common SP symptom. Tuberculosis is the most common etiological component of SP. Eighty-five percent of cases were successfully treated by tube thoracostomy. Conclusion: SP was more common in males and during the third and fifth decades of life. Secondary SP was more common than primary SP. Smoking history is an important risk factor for SP. Evaluating the clinical profile helps in assessing the etiology of SP. Early screening for risk factors and detection of comorbidities helps in the prevention of SP.

Understanding the association between pain and delirium in older hospital inpatients: systematic review and meta-analysis.

Delirium and pain are common in older adults admitted to hospital. The relationship between these is unclear, but clinically important. We aimed to systematically review the association between pain (at rest, movement, pain severity) and delirium in this population. PubMed, EMBASE, CINAHL, PsycINFO, Cochrane and Web of Science were searched (January 1982-November 2022) for Medical Subject Heading terms and synonyms ('Pain', 'Analgesic', 'Delirium'). Study eligibility: (1) validated pain measure as exposure, (2) validated delirium tool as an outcome; participant eligibility: (1) medical or surgical (planned/unplanned) inpatients, (2) admission length ≥ 48h and (3) median cohort age over 65years. Study quality was assessed with the Newcastle Ottawa Scale. We collected/calculated odds ratios (ORs) for categorical data and standard mean differences (SMDs) for continuous data and conducted multi-level random-intercepts meta-regression models. This review was prospectively registered with PROSPERO [18/5/2020] (CRD42020181346). Thirty studies were selected: 14 reported categorical data; 16 reported continuous data. Delirium prevalence ranged from 2.2 to 55%. In the multi-level analysis, pain at rest (OR 2.14; 95% confidence interval [CI] 1.39-3.30), movement (OR 1.30; 95% CI 0.66-2.56), pain categorised as 'severe' (OR 3.42; 95% CI 2.09-5.59) and increased pain severity when measured continuously (SMD 0.33; 95% CI 0.08-0.59) were associated with an increased delirium risk. There was substantial heterogeneity in both categorical (I2 = 0%-77%) and continuous analyses (I2 = 85%). An increase in pain was associated with a higher risk of developing delirium. Adequate pain management with appropriate analgesia may reduce incidence and severity of delirium.

Prevention and management of enteral nutrition-related diarrhea among adult inpatients: a best practice implementation project.

Diarrhea, the most common complication for patients during enteral nutrition, poses a range of risks and care burdens. Medical staff are aware of the importance of proactively preventing and managing enteral nutrition-related diarrhea. However, clinical prevention and management methods are not standardized, and the scientific basis and effectiveness of these methods need to be further verified. This project aimed to promote evidence-based practices for the prevention and management of enteral nutrition-related diarrhea among adult inpatients in a public tertiary hospital in China. This project was guided by the JBI Evidence Implementation Framework and used the JBI Practical Application of Clinical Evidence System (PACES) and the JBI Getting Research into Practice (GRiP) tools. Twelve audit criteria were developed to conduct a baseline audit to measure compliance with best practices. A barrier analysis was conducted, and strategies were implemented to overcome the barriers. The project was finalized with a follow-up audit to determine any changes in compliance with best practices. The overall compliance rate for the audit criteria increased from 27.37% at baseline to 89.62% in the follow-up audit, with six criteria achieving a compliance rate of 100%. The implementation of evidence-based practices can effectively narrow the gap between current practice and best practice. This project improved the ability of medical staff to prevent and manage enteral nutrition-related diarrhea, as well as promoting evidence-based practice in the hospital. http://links.lww.com/IJEBH/A168.

Prevalence, risk factors and impact of delirium in adult inpatients in a tertiary care hospital: A point prevalence study.

To describe the point prevalence, risk factors and possible outcomes of delirium in inpatients. A cross-sectional point prevalence study. Delirium is an acute brain syndrome that negatively affects patients, healthcare professionals and institutions alike; it is common in inpatient settings and is preventable in about one third of cases. Although guidelines recommend systematic screening and assessment, delirium is often unrecognised, undiagnosed and uncoded. There is a lack of valid data on this patient safety indicator in German-speaking countries. The study was conducted in a tertiary care hospital in Switzerland on 5 July 2022. Specially trained registered nurses collected data from all patients meeting the inclusion criteria using CAM, ICDSC or mCAM-ED. Data were analysed descriptively with stratification by delirium status, setting and surgery. The point prevalence across all settings was 6.9% (27/390), with large variation between settings: ICU 28.6% (4/14), IMC 28.0% (7/25), wards 4.6% (15/326) and ED 4% (1/25). Surgical patients were almost twice as likely to be affected as medical patients (8.9% vs. 4.8%). Patients with delirium differed most clearly from those without by having a larger number of ICD-10 F-diagnoses, a larger number of medications and higher age, which are known risk factors. Moreover, those with delirium had more missed diagnoses, increased mortality, more adverse events and higher costs. A significant number of patients experienced delirium and adverse clinical outcomes. Missed delirium diagnoses may further jeopardise patient safety and result in lost revenue. It remains unclear to what extent the risk factors and effects of delirium are causal and what determinants underlie missed diagnoses. Consistent identification of high-risk patients and treatment settings with elevated risk, accompanied by the implementation of effective preventive and management strategies, is critical to addressing delirium.

Predictive Power of Dependence and Clinical-Social Fragility Index and Risk of Fall in Hospitalized Adult Patients: A Case-Control Study.

Accidental falls are among the leading hospitals' adverse events, with incidence ranging from 2 to 20 events per 1.000 days/patients. The objective of this study is to assess the relationship between in-hospital falls and the score of 3 DEPendence and Clinical-Social Fragility indexes. A monocentric case-control study was conducted by retrieving data of in-hospital patients from the electronic health records. Significant differences between the mean scores at the hospital admission and discharge were found. The BRASS scale mean (SD) values at the admission and at the discharge were also significantly higher in cases of in-hospital falls: at the admission 10.2 (±7.7) in cases versus 7.0 (±8.0) in controls ( P = 0.003); at the discharge 10.0 (±6.4) versus 6.7 (±7.5) ( P = 0.001). Barthel index mean (SD) scores also presented statistically significant differences: at the admission 60.3 (±40.6) in cases versus 76.0 (±34.8) in controls ( P = 0.003); at discharge 51.3 (±34.9) versus 73.3 (±35.2) ( P = 0.000).Odds ratios were as follows: for Barthel index 2.37 (95% CI, 1.28-4.39; P = 0.003); for Index of Caring Complexity 1.45 (95% CI, 0.72-2.91, P = 0. 255); for BRASS index 1.95 (95% CI, 1.03-3.70, P = 0.026). With BRASS index, the area under the curve was 0.667 (95% CI, 0.595-0.740), thus indicating a moderate predictive power of the scale. The use of only Conley scale-despite its sensitivity and specificity-is not enough to fully address this need because of the multiple and heterogeneous factors that predispose to in-hospital falls. Therefore, the combination of multiple tools should be recommended.

Epidemiology and factors associated with mortality among pediatric major trauma patients in Nova Scotia: A 17-year retrospective analysis

BackgroundMajor traumatic injury in the pediatric population requires further evaluation to improve patient outcomes. Relatively few Canadian studies have investigated pediatric trauma using population-based data. Our objectives were to describe the epidemiology of pediatric major trauma in Nova Scotia and identify factors associated with in-hospital mortality. MethodsRetrospective cohort study of pediatric major trauma patients (age <18 years) injured in Nova Scotia over a 17-year period (April 2001-March 2018). Data were collected from the Nova Scotia Trauma Registry. Characteristics were compared between patient subgroups using t-tests, chi-square analyses and Fisher's exact test. Temporal trends were evaluated using the Mann-Kendall test. Incidence and mortality rates were mapped using ArcGIS Pro. A multivariate logistic regression model was created to assess for factors associated with in-hospital mortality. ResultsA total of 1258 injuries were observed over the 17-year study period. The incidence of pediatric major trauma was 41.7 per 100,000 person-years. Most patients were male (819/1258; 65.1 %) and resided in urban areas (764/1258; 60.7 %). Blunt trauma accounted for 86.2 % (1084/1258) of injuries, and motor vehicle collisions were the most common cause (448/1258; 35.6 %). Incidence and mortality rates were highest in the 15–17 year age group, with a trend towards increasing incidence among females (p = 0.011). Mortality was 17.2 % (217/1258) of patients; 10.9 % (137/1258) died pre-hospital. No trends were detected in mortality rates. The regression model showed increased odds of in-hospital mortality for every point increase in the ISS (OR 1.05; 95 % CI 1.02 to 1.09) and for every unit decrease in scene GCS (OR 0.63; 95 % CI 0.56–0.71). Rural patients were 2 times more likely to die in-hospital versus urban patients (OR 2.40; 95 % CI 1.01–5.69), and patients injured at home were 6 times more likely to die compared to those injured in other locations (OR 6.19; 95 % CI 1.01–38.11). ConclusionPediatric trauma remains a major public health issue in Canada and beyond. Greater efforts are required to expand our understanding of trauma epidemiology and develop targeted injury prevention strategies, especially for rural inhabitants.

Prognostic value of geriatric and cardiac parameters for one-year mortality in older heart failure patients. A multicentre, observational, prospective study

ABSTRACT Purpose Heart failure is prevalent among older people and has a poor prognosis. The aim of this study is to identify potential prognostic, geriatric, and cardiac parameters which could help clinicians identify older heart failure patients at high risk for one-year mortality. Methods The multicentre, observational cohort study which included 147 heart failure patients aged ≥75 years, hospitalized in the cardiac or geriatric department in two hospitals. One-year survival was the outcome measure. For univariate analysis Chi-square test and independent sample T-test were used; for multivariate analysis Logistic regression and Cox regression for time-dependent analysis. Results One-year mortality was 28% (41/147). One-year survivors and non-survivors did not differ in the following characteristics: age, gender, sodium level at hospital discharge, ejection fraction, NYHA Class, basic and instrumental activities of daily living, and the presence of a geriatric risk profile. There was a significant lower systolic blood pressure at discharge in non-survivors compared to one-year-survivors (mean 125.26 mmHg vs. 137.59 mmHg). Non-survivors had more severe underlying comorbidities according to the age adjusted Charlson Comorbidity index (CCI) (mean 8.80 vs. 7.40). Both logistic and Cox regression showed a higher risk and rate of mortality with decreasing systolic blood pressure at discharge (OR 0.963, p=0.001 and HR 0.970, p<0.001) and with increasing CCI (OR 1.344, p=0.002 and HR 1.269, p=0.001); the other variables were not significantly related. Conclusion Lower blood pressure and more severe comorbidities, but not functionality nor the presence of a geriatric risk profile, are related to one-year mortality in older, in-hospital heart failure patients.

Evaluation of risk factors associated with hard-to-heal wound infection in a tertiary care hospital.

The incidence of hard-to-heal wound infection, especially as a result of multidrug-resistant Gram-negative organisms, has increased in recent years. The reason for the increase is multifactorial and the ability of these pathogenic isolates to form biofilms is one of the important risk factors in wound infection. This study aimed to evaluate the risk factors associated with such cases. This prospective analytical study, conducted over a period of two months, included pus or tissue samples from hospital inpatients with Gram-negative hard-to-heal wound infection. The samples were processed with conventional microbiological techniques. Patient demographic details and the presence of various risk factors were recorded. Biofilm production was detected by tissue culture plate method in the laboratory. The data were analysed using SPSS version 21 (IBM Ltd., US). The experimental cohort comprised 200 patients. Klebsiella spp. was the most common identified organism, followed by Escherichia coli and Pseudomonas spp. Carbapenem resistance was observed in 106 (53%) strains. Almost 66% of the strains showed biofilm formation. On evaluation of associated risk factors, age (p=0.043), presence of biofilms (p=0.0001), diabetes (p=0.002), hypertension (p=0.02) and medical device use (p=0.008) had significant association, whereas sex, previous surgery and prior antibiotic use had no significant impact on the chronicity of the wound. In this study, chronicity of wounds was observed to be associated with multiple risk factors, especially the biofilm-forming ability of the strain. Biofilms are difficult to eradicate and additional measures, such as physical debridement, are important for resolving chronicity. Knowledge about specific risk factors would also allow clinicians a better understanding of the healing process and drive appropriate wound care interventions. A grant was received from the Indian Council of Medical Research (ICMR) for this work (grant ID: 2017-02686). The authors have no conflicts of interest to declare.

A comparison of in-hospital stroke and community- onset stroke outcomes after endovascular thrombectomy at a tertiary level hospital in Taiwan

Background: While acute-phase thrombectomy is a recognized treatment for main cerebral artery occlusion, variability exists in outcomes for in-hospital stroke and community-onset stroke patients undergoing endovascular thrombectomy. This study investigates the prognostic differences between in-hospital stroke and community-onset stroke patients in an Asian context, with a focus on the impact of patient transfer processes on treatment outcomes. Methods: Data were collected from in-hospital stroke patients who underwent endovascular thrombectomy in a tertiary medical center between January 2017 and December 2020. Propensity score matching with a ratio of 1:4 was performed to compare in-hospital stroke and community-onset stroke patients based on sex, age, NIHSS, and occluded vessel location. Results: The study included 20 in-hospital stroke and 80 community-onset stroke patients, with no significant difference in successful recanalization rates, complications, mortality rates, and NIHSS and mRS scores between the groups. The community-onset stroke group had longer times to treatment, particularly among transferred patients. A high proportion of in-hospital stroke patients had undergone surgery before their stroke, and a greater incidence of heart failure was noted in this group. Conclusion: Despite pre-stroke surgical treatments and a higher rate of heart failure in in-hospital stroke patients, prompt endovascular thrombectomy resulted in comparable outcomes to community- onset stroke patients. The study underscores the importance of reducing treatment times, especially for transferred patients, to improve stroke care efficacy.

Antibiotic consumption and antibiotics occurrence into the environment: a case study of hospital in Metro, Lampung

Increased antibiotic consumption has exposed bacterial communities and environmental ecosystems to large amounts of antibiotic residues derived from the excretion of irrationally consumed antibiotics. This study provides an overview of antibiotic consumption patterns in hospital inpatients and the distribution of residues released into the environment. Medical record data was used to calculate the amount of consumption from hospital inpatients, and based on the type of antibiotics that have a DU90% value, ecotoxicological risk calculations were carried out to estimate the level of danger that occurs in the environment. A total of 27 types of antibiotics were prescribed, with a total consumption of 20504.42 Kg/year. Antibiotics such as ceftriaxone, cefixime, cefadroxil, and levofloxacin are the most widely used antibiotics based on medical record data. The results of estimating the release of antibiotic residues in wastewater obtained ecotoxicological risk values for algae, invertebrates, and fish greater than one (RQs&gt;1). This condition indicates an ecotoxicological risk at the health facility site due to the release of antibiotic residues into the river water body from the WWTP outlet. The release of antibiotic residues into the water can result in ecosystem damage and pollution of the aquatic environment.

Frailty in an Adult Acute Hospital Population: Predictors, Prevalence, and Outcomes.

Frailty is common among older hospital inpatients. While studies describe frailty prevalence in acute hospitals, it is usually based upon retrospective hospital-coded data or brief screening on admission rather than comprehensive geriatric assessment (CGA). Further, little is known about differences between pre-admission and current frailty status. Given this, we investigated the prevalence of pre-frailty and frailty among adult inpatients in a large university hospital after CGA. Of the 410 inpatients available, 398 were included in the study, with a median age of 70 years; 56% were male. The median length of stay (LOS) at review was 8 days. The point prevalence of frailty was 30% versus 14% for pre-frailty. The median Clinical Frailty Scale score pre-admission was 3/9, which was significantly lower than at review, which was 4/9 (p < 0.001). After adjusting for age and sex, frailty was associated with greater odds of prolonged LOS (odds ratio [OR] 1.7, p = 0.045), one-year mortality (OR 2.1, p = 0.006), and one-year institutionalisation (OR 9, p < 0.001) but not re-admission. Frailty was most prevalent on medical and orthopaedic wards. In conclusion, CGA is an important risk assessment for hospitalised patients. Frailty was highly prevalent and associated with poor healthcare outcomes. Frailty status appears to worsen significantly during admission, likely reflecting acute illness, and it may not reflect a patient's true frailty level. The development of frailty clinical care pathways is recommended in order to address the poor prognosis associated with a diagnosis of frailty in this setting.

Evaluation of the safety, efficacy and feasibility of ‘at-home’ capsule endoscopy

ObjectiveThe role of small bowel capsule endoscopy (SBCE) in diagnosing gastrointestinal diseases has long been established. Recently, colon CE (CCE) has been suggested as an alternative to colonoscopy. CE has...
