IntroductionThe primary goal of quality improvement is to enhance patient outcomes, particularly in the emergency department (ED). Timely and effective care is crucial in these situations. By comprehending the challenges,...

Low respiratory quotient correlates with high mortality in patients undergoing mechanical ventilation

Oxygen consumption (VO2), carbon dioxide generation (VCO2), and respiratory quotient (RQ), which is the ratio of VO2 to VCO2, are critical indicators of human metabolism. To seek a link between the patient's metabolism and pathophysiology of critical illness, we investigated the correlation of these values with mortality in critical care patients. This was a prospective, observational study conducted at a suburban, quaternary care teaching hospital. Age 18years or older healthy volunteers and patients who underwent mechanical ventilation were enrolled. A high-fidelity automation device, which accuracy is equivalent to the gold standard Douglas Bag technique, was used to measure VO2, VCO2, and RQ at a wide range of fraction of inspired oxygen (FIO2). We included a total of 21 subjects including 8 post-cardiothoracic surgery patients, 7 intensive care patients, 3 patients from the emergency room, and 3 healthy volunteers. This study included 10 critical care patients, whose metabolic measurements were performed in the ER and ICU, and 6 died. VO2, VCO2, and RQ of survivors were 282 +/- 95mL/min, 202 +/- 81mL/min, and 0.70 +/- 0.10, and those of non-survivors were 240 +/- 87mL/min, 140 +/- 66mL/min, and 0.57 +/- 0.08 (p=0.34, p=0.10, and p<0.01), respectively. The difference of RQ was statistically significant (p<0.01) and it remained significant when the subjects with FIO2<0.5 were excluded (p<0.05). Low RQ correlated with high mortality, which may potentially indicate a decompensation of the oxygen metabolism in critically ill patients.

The quality of life among children with epilepsy in resource-limited settings: A pilot study in a paediatric neurology clinic at a quaternary care teaching hospital

Background. An important part of holistic care management of children with epilepsy (CWE) is measuring their health-related quality of life (HRQOL). However, little is known about the HRQOL of CWE who live in resource-limited settings, particularly in South Africa. Objectives. To assess the HRQOL of CWE and to identify the possible factors that correlate with HRQOL including demographic variables and epilepsy health-related factors. Methods. A cross-sectional prospective quantitative study was undertaken at the paediatric neurology outpatient clinic at Inkosi Albert Luthuli Hospital (IALCH), a quaternary care teaching hospital in Durban, South Africa. Participants were recruited during the period between December 2019 and February 2020. CWE between 2 and 12 years old with no comorbid syndromic disorder or other chronic diseases accompanied by English-speaking caregivers were included in the study. We used the Pediatric Quality of Life Inventory 4.0 (PedsQL 4.0) generic core parent-proxy questionnaire modified with separate sociodemographic and epilepsy data collection sheets. Results. One hundred and twenty participants were recruited. The majority of patients (54.2%) had generalised epilepsy. The aetiology of epilepsy was unknown in 40.8% of patients. The most commonly used anti-seizure medication was sodium valproate (39.2%). The mean of the total score of HRQOL (SD) (coefficient of variation %) was 66.7 (24.1 (36.1). School attendance p-value&lt;0.001, financial aid for indigent families p 0.047, monotherapy p&lt;0.001, absence of disability p&lt;0.001 and absence of comorbidity p &lt;0.001were strongly associated with good HRQOL total scores. Conclusion. CWE attending IALCH in Durban, South Africa, have compromised HRQOL scores. The variables that significantly correlate with better HRQOL scores are school attendance, receiving financial aid for indigent families, monotherapy, and absence of disabilities and comorbidities. We recommend a multicentre study that involves a larger number of epileptic children with the employment of the epilepsy-specific PedsQL 4.0 module translated into local languages.

Association of Internal Medicine Point of Care Ultrasound (POCUS) with Length of Stay, Hospitalization Costs, and Formal Imaging: a Prospective Cohort Study.

Background: Point of care ultrasound (POCUS) use has rapidly expanded among internal medicine (IM) physicians in practice and residency training programs. Many benefits have been established; however, studies demonstrating the impact of POCUS on system metrics are few and mostly limited to the emergency department or intensive care setting. The study objective was to evaluate the impact of inpatient POCUS on patient outcomes and hospitalization metrics. Methods: Prospective cohort study of 12,399 consecutive adult admissions to 22 IM teaching attendings, at a quaternary care teaching hospital (7/1/2011-6/30/2015), with or without POCUS available during a given hospitalization. Multivariable regression and propensity score matching (PSM) analyses compared multiple hospital metric outcomes (costs, length of stay, radiology-based imaging, satisfaction, etc.) between the "POCUS available" vs. "POCUS unavailable" groups as well as the "POCUS available" subgroups of "POCUS used" vs. "POCUS not used". Results: Patients in the "POCUS available" vs. "POCUS unavailable" group had lower mean total and per-day hospital costs ($17,474 vs. $21,803, p<0.001; $2,805.88 vs. $3,557.53, p<0.001), lower total and per-day radiology cost ($705.41 vs. $829.12, p<0.001; $163.11 vs. $198.53, p<0.001), fewer total chest X-rays (1.31 vs. 1.55, p=0.01), but more chest CTs (0.22 vs 0.15; p=0.001). Mean length of stay (LOS) was 5.77 days (95% CI = 5.63, 5.91) in the "POCUS available" group vs. 6.08 95% CI (5.66, 6.51) in the "POCUS unavailable" group (p=0.14). Within the "POCUS available" group, cost analysis with a 4:1 PSM (including LOS as a covariate) compared patients receiving POCUS vs. those that could have but did not, and also showed total and per-day cost savings in the "POCUS used" subgroup ($15,082 vs. 15,746; p<0.001 and $2,685 vs. $2,753; p=0.04). Conclusions: Availability and selected use of POCUS was associated with a meaningful reduction in total hospitalization cost, radiology cost, and chest X-rays for hospitalized patients.

Impact of a Repatriation Program Between Quaternary and Community Hospitals.

Capacity challenges at quaternary hospitals cause delays or denials in patient transfers from community hospitals that can compromise quality and safety. Repatriation is an innovative approach to increase capacity at the quaternary hospital by transferring a patient back to their originating community hospital after the quaternary portion of their care is completed. A repatriation program was implemented at a large quaternary care teaching hospital over a one-year period (2020 to 2021). The authors characterized the rate of successful repatriation and associated patient characteristics, determined the impact on quaternary hospital capacity in terms of bed days saved, and estimated the resultant number of backfilled admissions that could be accommodated. The research team also monitored the rate of readmissions for repatriations back to the quaternary hospital. Overall, 215 repatriations were attempted, and 103 (47.5%) were successful. The most common diagnoses were sepsis (13, 12.6%), stroke (12, 11.7%), intracranial bleed (10, 9.7%), gastrointestinal perforation/obstruction (9, 8.7%), and trauma (9, 8.7%). The median length of stay at the quaternary hospital was 13 days (interquartile range [IQR] 7-20) and 12 days (IQR 4-26) at the community hospital. There were 2,842 bed days saved at the quaternary hospital, with a backfill opportunity of 431 admissions. The readmission rate to the quaternary hospital was 1.9%. By dynamically matching patient need with hospital capability at different phases of the patient's care, Repatriation can save bed days at the quaternary hospital, creating capacity to improve access for patients needing timely transfer. The low observed readmission rate suggests that repatriation is safe.

Continuous and repeat metabolic measurements compared between post-cardiothoracic surgery and critical care patients

ObjectiveUsing a system, which accuracy is equivalent to the gold standard Douglas Bag (DB) technique for measuring oxygen consumption (VO2), carbon dioxide generation (VCO2), and respiratory quotient (RQ), we aimed to continuously measure these metabolic indicators and compare the values between post-cardiothoracic surgery and critical care patients.MethodsThis was a prospective, observational study conducted at a suburban, quaternary care teaching hospital. Age 18 years or older patients who underwent mechanical ventilation were enrolled.ResultsWe included 4 post-surgery and 6 critical care patients. Of those, 3 critical care patients died. The longest measurement reached to 12 h and 15 min and 50 cycles of repeat measurements were performed. VO2 of the post-surgery patients were 234 ± 14, 262 ± 27, 212 ± 16, and 192 ± 20 mL/min, and those of critical care patients were 122 ± 20, 189 ± 9, 191 ± 7, 191 ± 24, 212 ± 12, and 135 ± 21 mL/min, respectively. The value of VO2 was more variable in the post-surgery patients and the range of each patient was 44, 126, 71, and 67, respectively. SOFA scores were higher in non-survivors and there were negative correlations of RQ with SOFA.ConclusionsWe developed an accurate system that enables continuous and repeat measurements of VO2, VCO2, and RQ. Critical care patients may have less activity in metabolism represented by less variable values of VO2 and VCO2 over time as compared to those of post-cardiothoracic surgery patients. Additionally, an alteration of these values may mean a systemic distinction of the metabolism of critically ill patients.

An Automation System Equivalent to the Douglas Bag Technique Enables Continuous and Repeat Metabolic Measurements in Patients Undergoing Mechanical Ventilation

To develop a system that is equivalent to the gold standard Douglas Bag (DB) technique for measuring oxygen consumption (V̇o2), carbon dioxide generation (V̇co2), and respiratory quotient (RQ) and to validate its use in clinical settings. This was a prospective, observational study conducted at a suburban, quaternary care teaching hospital. Healthy volunteers and patients 18 years or older who received mechanical ventilation were enrolled. Data from 3 healthy volunteers and 7 patients were analyzed in this study. The interrater reliability between the automation device and DB methods were 0.999, 0.993, and 0.993 for V̇o2, V̇co2, and RQ, respectively. In healthy volunteers, mean (SD) V̇o2, V̇co2, and RQ measured by DB were 411 (100) mL/min, 288 (79) mL/min, and 0.70 (0.03) at high fraction of inspired oxygen (Fio2) and 323 (46) mL/min, 280 (45) mL/min, and 0.85 (0.05) at normal Fio2, respectively. V̇o2 was significantly higher (P < 0.05) and RQ was lower (P < 0.01) in the high Fio2 group as compared to those in the normal Fio2 group. Values measured by the automation system were 227 (31) mL/min, 141 (18) mL/min, and 0.62 (0.04) at high Fio2 and 209 (25) mL/min, 147 (18) mL/min, and 0.70 (0.06) at normal Fio2, respectively. RQ was significantly lower (P < 0.05) in the high Fio2 group as compared to the normal Fio2 group. We also successfully performed continuous and repeat measurements by using the device. The longest measurement reached 12 hours 15 minutes, including 50 cycles of repeat measurements that are equivalent to the DB technique as described above. We developed an automation system that enables repeat measurements of V̇o2, V̇co2, and RQ, and the accuracy was equivalent to the DB technique. High Fio2 may decrease RQ because of an increase in V̇o2.

Nursing organisation during COVID-19: experiences of an unaided, not-for-profit quaternary care teaching hospital in India.

India reported its index case of coronavirus disease 2019 (COVID-19) in January 2020 and since then there has been an alarming rise in cases. In response to the worsening pandemic and the challenge presented by COVID-19 for hospitals in the public sector, the Government of India asked the country's private hospitals to reserve a percentage of their beds for COVID-19 patients. This article describes how nursing services at the Christian Medical College, Vellore - an unaided, not-for-profit quaternary care teaching hospital in Tamil Nadu, India - addressed various challenges to ensure a sustained, high-quality nursing care response to increased patient load. The main challenges included changing COVID-19 policies, ensuring the hospital was prepared to care for COVID-19 patients, and ensuring the availability of nurses. The article demonstrates how proactive planning, empowered involvement of nursing leaders and collaborative efforts resulted in deployment and training of 1,400 nurses, and ensured coordinated care for more than 10,000 patients with COVID-19.

Perception and Practice on the Management of Pediatric Diarrhea in Thailand

Background: Various observational and survey-based studies have shown suboptimal adherence to clinic practice guidelines, on management of pediatric diarrhea in Thailand. Objective: To define clinical practice of acute diarrhea in young children at a quaternary care teaching hospital, and to determine factors associated with the management. Materials and Methods: The authors initially reviewed the medical records of 1,500 children aged one month to five years with a diagnosis code of acute diarrhea between January 2017 and December 2018. The authors excluded children who received treatment from other centers or had other final primary diagnosis. This resulted in 802 cases, from which the authors collected presenting symptoms, investigations, and management. Results: The median age was 16 months (IQR 9, 29). Most children had no documentation of dehydration status (60%) and did not have mucous or blood in their stools (80%). Blood or stool tests were performed in less than 20% of the cases. Advice on lactose avoidance was noted in 16%, while antibiotics and hospital admission were noted in less than 10%. Domperidone was prescribed in 42%, while ondansetron was given in 8.7%. Multivariate logistic regression analyses showed various independent factors associated with lactose avoidance including age of less than 24 months, type of physician, vomiting, and hospital admission, antibiotic used when there was high grade fever of 39℃ or higher, mucous bloody stools, performed blood culture, and stool culture, and hospital admission when there was moderate dehydration, complete blood count, and performed stool culture. Conclusion: Recording dehydration status is suboptimal. Low rates of investigations complied with most clinical scenarios. Findings on the pediatric acute diarrhea-related management may provide future opportunities to improve education and further conduct quality improvement projects among clinicians.

Impact of 24/7 Onsite Emergency Radiology Staff Coverage on Emergency Department Workflow.

Assess the impact of 24/7/365 emergency trauma radiology (ETR) coverage on Emergency Department (ED) patient flow in an urban, quaternary-care teaching hospital. Patient ED visit and imaging information were extracted from the hospital patient care information system for 2008 to 2018. An interrupted time-series approach with a comparison group was used to study the impact of 24/7/365 ETR on average monthly ED length of stay (ED-LOS) and Emergency Physician to disposition time (EP-DISP). Linear regression models were fit with abrupt and permanent interrupts for 24/7/365 ETR, a coefficient for comparison series and a SARIMA error term; subgroup analyses were performed by patient arrival time, imaging type and chief complaint. During the study period, there were 949,029 ED visits and 739,796 diagnostic tests. Following implementation of 24/7/365 coverage, we found a significant decrease in EP-DISP time for patients requiring only radiographs (-29 min;95%CI:-52,-6) and a significant increase in EP-DISP time for major trauma patients (46 min;95%CI:13,79). No significant change in patient throughput was observed during evening hours for any patient subgroup. For overnight patients, there was a reduction in EP-DISP for patients with symptoms consistent with stroke (-78 min;95%CI:-131,-24) and for high acuity patients who required imaging (-33 min;95%CI:-57,-10). Changes in ED-LOS followed a similar pattern. At our institution, 24/7/365 in-house ETR staff radiology coverage was associated with improved ED flow for patients requiring only radiographs and for overnight stroke and high acuity patients. Major trauma patients spent more time in the ED, perhaps reflecting the required multidisciplinary management.

Awake Prone Positioning Strategy for Nonintubated Hypoxic Patients with COVID-19: A Pilot Trial with Embedded Implementation Evaluation.

Rationale: Prone positioning is an appealing therapeutic strategy for nonintubated hypoxic patients with coronavirus disease (COVID-19), but its effectiveness remains to be established in randomized controlled trials.Objectives: To identify contextual factors relevant to the conduct of a definitive clinical trial evaluating a prone positioning strategy for nonintubated hypoxic patients with COVID-19.Methods: We conducted a cluster randomized pilot trial at a quaternary care teaching hospital. Five inpatient medical service teams were randomly allocated to two treatment arms: 1) usual care (UC), consisting of current, standard management of hypoxia and COVID-19; or 2) the Awake Prone Positioning Strategy (APPS) plus UC. Included patients had positive severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) testing or suspected COVID-19 pneumonia and oxygen saturation less than 93% or new oxygen requirement of 3 L per minute or greater and no contraindications to prone positioning. Oxygenation measures were collected within 48 hours of eligibility and included nadir oxygen saturation to fraction of inspired oxygen (S/F) ratio and time spent with S/F ratio less than 315. Concurrently, we conducted an embedded implementation evaluation using semistructured interviews with clinician and patient participants to determine contextual factors relevant to the successful conduct of a future clinical trial. The primary outcomes were drawn from an implementation science framework including acceptability, adoption, appropriateness, effectiveness, equity, feasibility, fidelity, and penetration.Results: Forty patients were included in the cluster randomized trial. Patients in the UC group (n = 13) had a median nadir S/F ratio over the 48-hour study period of 216 (95% confidence interval [95% CI], 95–303) versus 253 (95% CI, 197–267) in the APPS group (n = 27). Patients in the UC group spent 42 hours (95% CI, 13–47) of the 48-hour study period with an S/F ratio below 315 versus 20 hours (95% CI, 6–39) for patients in the APPS group. Mixed-methods analyses uncovered several barriers relevant to the conduct of a successful definitive randomized controlled trial, including low adherence to prone positioning, large differences between physician-recommended and patient-tolerated prone durations, and diffusion of prone positioning into usual care.Conclusions: A definitive trial evaluating the effect of prone positioning in nonintubated patients with COVID-19 is warranted, but several barriers must be addressed to ensure that the results of such a trial are informative and readily translated into practice.

Hemodynamic effects of increased intra-abdominal pressure in critically ill children

ObjectiveTo evaluate the influence of intra-abdominal pressure on the cardiac index (CI) at different intra-abdominal hypertension grades achieved when performing an abdominal compression maneuver (ACM). Evaluating the effectiveness of the ACM in distending the left internal jugular vein (LIJV).MethodsProspective observational study conducted in the PICU of a quaternary care teaching hospital. Participants underwent the ACM and the IAP was measured with an indwelling urinary catheter. At each IAH grade reached during the ACM, the CI was measured by transthoracic echocardiography and the LIJV cross-sectional area (CSA) was determined by ultrasonography.ResultsTwenty-four children were included (median age and weight of 3.5 months and 6.37 kg, respectively). The median CI observed at baseline and during IAH grades I, II, III, and IV were 3.65 L/min/m2 (IQR 3.12−4.03), 3.38 L/min/m2 (IQR 3.04−3.73), 3.16 L/min/m2 (IQR 2.70−3.53), 2.89 L/min/m2 (IQR 2.38−3.22), and 2.42 L/min/m2 (IQR 1.91−2.79), respectively. A 25% increase in the LIJV CSA area was achieved in 14 participants (58%) during the ACM.ConclusionThe ACM significantly increases IAP, causing severe reversible impairment in the cardiovascular system and is effective in distending the LIJV in just over half of the subjects. Even low levels of HIA can result in significant cardiac dysfunction in children. Therefore, health professionals should be aware of the negative hemodynamic repercussions caused by the increased IAP.

Value of the International Classification of Diseases code for identifying children with biliary atresia.

Background Although identifying cases in large administrative databases may aid future research studies, previous reports demonstrated that the use of the International Classification of Diseases, Tenth Revision (ICD-10) code alone for diagnosis leads to disease misclassification.Purpose We aimed to assess the value of the ICD-10 diagnostic code for identifying potential children with biliary atresia.Methods Patients aged <18 years assigned the ICD-10 code of biliary atresia (Q44.2) between January 1996 and December 2016 at a quaternary care teaching hospital were identified. We also reviewed patients with other diagnoses of code-defined cirrhosis to identify more potential cases of biliary atresia. A proposed diagnostic algorithm was used to define ICD-10 code accuracy, sensitivity, and specificity.Results We reviewed the medical records of 155 patients with ICD-10 code Q44.2 and 69 patients with other codes for biliary cirrhosis (K74.4, K74.5, K74.6). The accuracy for identifying definite/probable/possible biliary atresia cases was 80%, while the sensitivity was 88% (95% confidence interval [CI], 82%–93%). Three independent predictors were associated with algorithm-defined definite/probable/possible cases of biliary atresia: ICD-10 code Q44.2 (odds ratio [OR], 2.90; 95% CI, 1.09–7.71), history of pale stool (OR, 2.78; 95% CI, 1.18–6.60), and a presumed diagnosis of biliary atresia prior to referral to our hospital (OR, 17.49; 95% CI, 7.01–43.64). A significant interaction was noted between ICD-10 code Q44.2 and a history of pale stool (P<0.05). The area under the curve was 0.87 (95% CI, 0.84–0.89).Conclusion ICD-10 code Q44.2 has an acceptable value for diagnosing biliary atresia. Incorporating clinical data improves the case identification. The use of this proposed diagnostic algorithm to examine data from administrative databases may facilitate appropriate health care allocation and aid future research investigations.

Outcomes in Renal Cell Carcinoma With IVC Thrombectomy: A Multiteam Analysis Between an NCI-Designated Cancer Center and a Quaternary Care Teaching Hospital.

Interteam performance and Clavien-Dindo (C-D) complications in renal cell carcinoma with inferior vena cava thrombectomy (RCC-IVCT) have not been reported. We aimed to describe complications by the degree of complexity and surgical teams in a collaborative effort between a National Cancer Institute-designated Comprehensive Cancer Center and a Quaternary Care Teaching Hospital. Between January 2011 and May 2019, 73 consecutive RCC-IVCT were included. C-D grades III or higher were captured. Teams involved were urologic-oncology, vascular, hepatobiliary/transplant, and cardiothoracic. The Mayo Clinic tumor thrombus classification was used. Overall complication rate was 42% (n = 31). Nineteen percent had grade III, 18% had grade IV, and 6% had grade V complications. Patients with level IV thrombus had the highest in-hospital mortality rate (75%). Thrombus level did not show a correlation to complication rates (14% level I, 45% level II, 32% level III, 42% level IV). A positive correlation found between the number of teams involved and complication rates (35% with 2-team, 59% with 3-team, P = .059). Thromboembolic events (6% vs 24%, P = .02) and disposition other than home (22% vs 48%, P = .01) were statistically lower for the 2-team groups. Two-team in-hospital mortality was 1/51 (2%) versus 3-team (3/22,14%, (P = .07). No statistical differences were found in infections, thromboembolic events, and grades of complications between surgical teams. Despite similar interteam performance, the consistency of surgeons in high complexity cases could improve outcomes further. Complexity was higher for hepatobiliary/transplant and cardiothoracic teams. A combination of intraoperative events and patient selection (comorbidities and age) contributed to death. Overall, in-hospital mortality was lower than in most reported series.

Abstract 22: How Are We Doing At Treating Arteriovenous Malformations?

Background: Arteriovenous malformations (AVMs) are incompletely understood complex vascular lesions that can cause significant deformity and morbidity. This study reviews our experience with AVMs at a quaternary care teaching hospital. Methods: All patients treated for AVMs in our vascular anomaly clinic from 1991 to 2018 were reviewed. Data extraction included demographics, clinical presentation and course, radiology reports, and treatments. Progression was defined as advancement to a higher Schobinger stage (1 through 4) before treatment. Recurrence was defined as expansion following embolization or resection. Results: 58 patients met inclusion criteria. 60.3% lesions were located in the head and neck, 10.3% on the trunk, and 29.3% on the extremities. 60% patients were female, and average follow up time was 2.9 years. 18.9% patients presented at Stage 1, 54.7% at Stage 2, 24.5% at Stage 3, and 1.9% at Stage 4. 98% of lesions progressed to a higher Schobinger stage without intervention. 124 interventions, including surgery and embolization, were performed on our cohort. Patients treated with embolization alone had a per treatment recurrence rate of 59%, and patients treated with surgical resection had a per treatment recurrence rate of 33%. Advanced lesions had higher rates of recurrence (Stage 2 60%, Stage 3 83%, Stage 4 100%). More advanced lesions also recurred more quickly. 3 lesions treated at Stage 1 did not show evidence of recurrence. Conclusions: AVMs ultimately progress without intervention. We are not doing well at treating later stage AVMs as these lesions require a tremendous amount of resources and have a high rate of recurrence despite treatment. Our data suggests surgery had lower recurrences versus embolization alone. Treatment of lower-staged lesions may provide longer recurrence-free disease control.

Clinical Spectrum and Outcome of Neurosarcoidosis: A Retrospective Cohort Study from a Teaching Hospital in India.

Context:Neurosarcoidosis (NS) is a chronic disease with a diverse clinical spectrum, therapeutic response, and outcome. There is scarce literature from our country regarding the same.Aims:The aim of this study was to evaluate the clinical spectrum, therapeutic responses, and outcomes of NS in an Indian cohort.Settings and Design:In a cross-sectional study, we included all patients with NS treated at a quaternary care teaching hospital in India from January 2007 to October 2019.Subjects and Methods:Patients older than 18 years of age fulfilling the diagnostic criteria for NS from the Neurosarcoidosis Consortium Consensus Group were included in the study. The therapeutic response and the degree of disability at last follow-up were assessed.Results:We identified 48 patients, among them 3 were categorized as having definite NS, 30 probable NS, and 15 possible NS. Cranial neuropathy was the most common presentation (47.9%), followed by myelopathy (25%). Systemic involvement was identified in 95.83% and mediastinal lymph nodes were the most common site. Clinical improvement was seen in 65.8% and disease stabilized in 28.9%, while 5.26% deteriorated. Fifty percent recovered without any residual disability, while 26.3% had minor and 23.7% had major residual sequelae.Conclusions:NS is a diverse illness, with a heterogeneous spectrum of clinical presentation, treatment response, and outcome. Cranial neuropathy is the most common presenting feature and has a good prognosis while myelopathy has an unfavorable prognosis. Meningeal and brain parenchymal disease is difficult to diagnose accurately unless systemic involvement is present. The diagnosis of NS should be clinically suspected in the appropriate clinical setting, the presence of systemic involvement should be investigated, and histologic confirmation should be attempted.

Development and Validation of a Machine Learning Model to Aid Discharge Processes for Inpatient Surgical Care

Inpatient overcrowding is associated with delays in care, including the deferral of surgical care until beds are available to accommodate postoperative patients. Timely patient discharge is critical to address inpatient overcrowding and requires coordination among surgeons, nurses, case managers, and others. This is difficult to achieve without early identification and systemwide transparency of discharge candidates and their respective barriers to discharge. To validate the performance of a clinically interpretable feedforward neural network model that could improve the discharge process by predicting which patients would be discharged within 24 hours and their clinical and nonclinical barriers. This prognostic study included adult patients discharged from inpatient surgical care from May 1, 2016, to August 31, 2017, at a quaternary care teaching hospital. Model performance was assessed with standard cross-validation techniques. The model's performance was compared with a baseline model using historical procedure median length of stay to predict discharges. In prospective cohort analysis, the feedforward neural network model was used to make predictions on general surgical care floors with 63 beds. If patients were not discharged when predicted, the causes of delay were recorded. The primary outcome was the out-of-sample area under the receiver operating characteristic curve of the model. Secondary outcomes included the causes of discharge delay and the number of avoidable bed-days. The model was trained on 15 201 patients (median [interquartile range] age, 60 [46-70] years; 7623 [50.1%] men) discharged from inpatient surgical care. The estimated out-of-sample area under the receiver operating characteristic curve of the model was 0.840 (SD, 0.008; 95% CI, 0.839-0.844). Compared with the baseline model, the neural network model had higher sensitivity (52.5% vs 56.6%) and specificity (51.7% vs 82.6%). The neural network model identified 65 barriers to discharge. In the prospective study of 605 patients, causes of delays included clinical barriers (41 patients [30.1%]), variation in clinical practice (30 patients [22.1%]), and nonclinical reasons (65 patients [47.8%]). Summing patients who were not discharged owing to variation in clinical practice and nonclinical reasons, 128 bed-days, or 1.2 beds per day, were classified as avoidable. This cohort study found that a neural network model could predict daily inpatient surgical care discharges and their barriers. The model identified systemic causes of discharge delays. Such models should be studied for their ability to increase the timeliness of discharges.

Intraoperative Methadone Is Associated with Decreased Perioperative Opioid Use Without Adverse Events: A Case-Matched Cohort Study

To determine if there is an association of intraoperative methadone use and total perioperative opioid exposure in patients undergoing congenital heart surgeries. Retrospective, case-match cohort study. Single center quaternary care teaching hospital. Seventy-four patients with congenital heart disease (CHD) undergoing surgical repair or palliative surgery. Thirty-seven patients undergoing CHD surgeries receiving intraoperative methadone were matched to 37 patients based upon age and procedure who did not receive intraoperative methadone. The primary study outcome was to evaluate total opioid use in intravenous milligrams of morphine equivalents per kilogram (mg ME/kg) within the first 36-hours postoperatively. Mann-Whitney U test was used to compare total opioid exposure. The total opioid use was compared between groups. The methadone cohort required less opioids intraoperatively, in the first 12 hours postoperatively, and during the first 36 hours postoperatively (2.51 v 4.39 mg ME/kg, p < 0.001; 0.43 v 1.28 mg ME/kg, p = 0.001; and 0.83 v 1.91 mg ME/kg, p < 0.001) compared with the matched control cohort. There were no differences in clinical outcomes or adverse events. A dose-dependent reduction in opioid consumption in high- versus low-dose groups also was not observed. Intraoperative methadone use was associated with a decrease in perioperative opioid exposure in patients undergoing congenital heart surgery and was not associated with adverse events or prolonged durations of mechanical ventilation or ICU stay.

Do Otoliths Modulate Caloric Response? What Do Vemps and Cdp Measure? What Do These Tests Tell Us?

Objective: it has been documented in the literature that caloric responses with the lateral semicircular canal in a horizontal position are reduced, but not absent. This paper addresses what contributions to the caloric response, if any are made by the otoliths, and what influences on caloric response might be seen in patients with otolithic pathology. Study design: a prospective case series study. Setting: Tertiary and quaternary care teaching hospital. Patients: two normal subjects underwent “horizontal” calorics to document caloric response with the lateral semicircular canal in the horizontal position. This assessment was also carried out on eight sequential patients who were documented to have otolithic disease (as evidenced by abnormal VEMP assessment).

Treatment of acute ischemic stroke: Awareness among general practitioners

For promptly referral of a patient with acute ischemic stroke (AIS) for possible thrombolysis, general practitioners (GPs) need to equipped with the advanced knowledge of AIS treatment. We assessed the knowledge regarding treatment of AIS among GPs practicing in and around a quaternary care teaching hospital in south India. A total of 109 GPs who attend to medical emergencies were interviewed using a standard questionnaire. Of the 109 GPs interviewed, 54% felt that tissue plasminogen activator (tPA) can be used in the treating AIS, but only 24% had chosen tPA as the best treatment option and 22% opted for other agents like citicholine or edavarone. Only 17% were aware that tPA should be given within 3 h. and 35% felt that intra-arterial thrombolysis as a treatment option.. Only 30% felt the need for good sugar control and 37% wanted aggressive lowering of blood pressure. Majority of GPs are not clear about beneficial effects of thrombolysis and are not updated regarding BP and sugar control in the setting of AIS.
