Functional status in ICU survivors and out of hospital outcomes: a cohort study

OBJECTIVES: Functional status at hospital discharge may be a risk factor for adverse events among survivors of critical illness. We sought to examine the association between functional status at hospital discharge in survivors of critical care and risk of 90-day all-cause mortality after hospital discharge. DESIGN: Single-center retrospective cohort study. SETTING: Academic Medical Center. PATIENTS: Ten thousand three hundred forty-three adults who received critical care from 1997 to 2011 and survived hospitalization. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: The exposure of interest was functional status determined at hospital discharge by a licensed physical therapist and rated based on qualitative categories adapted from the Functional Independence Measure. The main outcome was 90-day post hospital discharge all-cause mortality. A categorical risk-prediction score was derived and validated based on a logistic regression model of the function grades for each assessment. In an adjusted logistic regression model, the lowest quartile of functional status at hospital discharge was associated with an increased odds of 90-day postdischarge mortality compared with patients with independent functional status (odds ratio, 7.63 [95% CI, 3.83-15.22; p < 0.001]). In patients who had at least 7 days of physical therapy treatment prior to hospital discharge (n = 2,293), the adjusted odds of 90-day postdischarge mortality in patients with marked improvement in functional status at discharge was 64% less than patients with no change in functional status (odds ratio, 0.36 [95% CI, 0.24-0.53]; p < 0.001). CONCLUSIONS: Lower functional status at hospital discharge in survivors of critical illness is associated with increased postdischarge mortality. Furthermore, patients whose functional status improves before discharge have decreased odds of postdischarge mortality.L30 TR001257 - NCATS NIH HH

Vitamin D Status and Community-Acquired Pneumonia: Results from the Third National Health and Nutrition Examination Survey

Objective: To investigate the association between serum 25-hydroxyvitamin D [25(OH)D] level and history of community-acquired pneumonia (CAP). Patients and Methods We identified 16,975 individuals (≥17 years) from the third National Health and Nutrition Examination Survey (NHANES III) with documented 25(OH)D levels. To investigate the association of 25(OH)D with history of CAP in these participants, we developed a multivariable logistic regression model, adjusting for demographic factors (age, sex, race, poverty-to-income ratio, and geographic location), clinical data (body mass index, smoking status, asthma, chronic obstructive pulmonary disease, congestive heart failure, diabetes mellitus, stroke, chronic kidney disease, neutropenia, and alcohol consumption), and season. Locally weighted scatterplot smoothing (LOWESS) was used to depict the relationship between increasing 25(OH)D levels and the cumulative frequency of CAP in the study cohort. Results: The median [interquartile range (IQR)] serum 25(OH)D level was 24 (IQR 18–32) ng/mL. 2.1% [95% confidence interval (CI): 1.9–2.3] of participants reported experiencing a CAP within one year of their participation in the national survey. After adjusting for demographic factors, clinical data, and season, 25(OH)D levels <30 ng/mL were associated with 56% higher odds of CAP [odds ratio 1.56; 95% confidence interval: 1.17–2.07] compared to levels ≥30 ng/mL. LOWESS analysis revealed a near linear relationship between vitamin D status and the cumulative frequency of CAP up to 25(OH)D levels around 30 ng/mL. Conclusion: Among 16,975 participants in NHANES III, 25(OH)D levels were inversely associated with history of CAP. Randomized controlled trials are warranted to determine the effect of optimizing vitamin D status on the risk of CAP

Hospital Nutrition Assessment Practice 2016 Survey

BackgroundMalnutrition is a significant problem for hospitalized patients in the United States. Nutrition assessment is an important step in recognizing malnutrition; however, it is not always performed using consistent parameters.MethodsA survey among U.S. American Society for Parenteral and Enteral Nutrition (ASPEN) members was conducted to collect data on nutrition assessment parameters used in hospitals and to establish how facilities use their electronic health record (EHR) to permit data retrieval and outcome reporting.ResultsThe survey was developed by the ASPEN Malnutrition Committee and was sent to 5487 U.S. ASPEN members, with 489 responding for a 9% response rate. Ninety‐eight percent of adult and 93% of pediatric respondents indicated a registered dietitian completed the nutrition assessment following a positive nutrition screen. Variables most frequently used among adult respondents included usual body weight, ideal body weight, and body mass index. Among pediatric respondents, weight‐for‐age and height‐for‐age percentiles and length/height‐for‐age percentile were most frequently used. Both adult and pediatric respondents indicated use of physical assessment parameters, including muscle and fat loss and skin assessment. Eighty‐seven percent of adult and 77% of pediatric respondents indicated they are using the Academy of Nutrition and Dietetics (Academy) and ASPEN Consensus Malnutrition Characteristics for Adult and Pediatric Malnutrition, respectively. Overall, 97% of respondents indicated nutrition assessment documentation was completed via an EHR. Of all respondents, 61% indicated lack of clinical decision support within their EHR.ConclusionThis survey demonstrated significant use of the Academy/ASPEN malnutrition consensus characteristics.Peer Reviewedhttps://deepblue.lib.umich.edu/bitstream/2027.42/146497/1/ncp10179_am.pdfhttps://deepblue.lib.umich.edu/bitstream/2027.42/146497/2/ncp10179.pdfhttps://deepblue.lib.umich.edu/bitstream/2027.42/146497/3/ncp10179-sup-0001-FigureS1.pd

Hypotension in ICU Patients Receiving Vasopressor Therapy

Vasopressor infusion (VPI) is used to treat hypotension in an ICU. We studied compliance with blood pressure (BP) goals during VPI and whether a statistical model might be efficacious for advance warning of impending hypotension, compared with a basic hypotension threshold alert. Retrospective data were obtained from a public database. Studying adult ICU patients receiving VPI at submaximal dosages, we analyzed characteristics of sustained hypotension episodes (>15 min) and then developed a logistic regression model to predict hypotension episodes using input features related to BP trends. The model was then validated with prospective data. In the retrospective dataset, 102-of-215 ICU stays experienced >1 hypotension episode (median of 2.5 episodes per day in this subgroup). When trained with 75% of retrospective dataset, testing with the remaining 25% of the dataset showed that the model and the threshold alert detected 99.6% and 100% of the episodes, respectively, with median advance forecast times (AFT) of 12 and 0 min. In a second, prospective dataset, the model detected 100% of 26 episodes with a median AFT of 22 min. In conclusion, episodes of hypotension were common during VPI in the ICU. A logistic regression model using BP temporal trend features predicted the episodes before their onset

THE FIRST REPORT OF A POSSIBLE SARS-CoV-2 REINFECTION IN NEPAL

oai:ojs2.jebas.org:article/1Since August 2020, a growing number of confirmed SARS-CoV-2 cases, after approximately three months, in most of them, again presented a new infection episode, which has been defined as reinfection. So far, no cases have been reported in Nepal, and still there is limited the number of them, especially of those fully confirmed. Here, we report a case and discuss its multiple implications in the ongoing COVID-19 pandemic

Admission vitamin D status is associated with discharge destination in critically ill surgical patients

Background: Discharge destination after critical illness is increasingly recognized as a valuable patient-centered outcome. Recently, vitamin D status has been shown to be associated with important outcomes such as length of stay (LOS) and mortality in intensive care unit (ICU) patients. Our goal was to investigate whether vitamin D status on ICU admission is associated with discharge destination. Methods: We performed a retrospective analysis from an ongoing prospective cohort study of vitamin D status in critical illness. Patients were recruited from two surgical ICUs at a single teaching hospital in Boston, Massachusetts. All patients had 25-hydroxyvitamin D (25OHD) levels measured within 24 h of ICU admission. Discharge destination was dichotomized as non-home or home. Locally weighted scatterplot smoothing (LOWESS) was used to graph the relationship between 25OHD levels and discharge destination. To investigate the association between 25OHD level and discharge destination, we performed logistic regression analyses, controlling for age, sex, race, body mass index, socioeconomic status, acute physiology and chronic health evaluation II score, need for emergent vs. non-emergent surgery, vitamin D supplementation status, and hospital LOS. Results: 300 patients comprised the analytic cohort. Mean 25OHD level was 19 (standard deviation 8) ng/mL and 41 % of patients had a non-home discharge destination. LOWESS analysis demonstrated a near-inverse linear relationship between vitamin D status and non-home discharge destination to 25OHD levels around 10 ng/mL, with rapid flattening of the curve between levels of 10 and 20 ng/mL. Overall, 25OHD level at the outset of critical illness was inversely associated with non-home discharge destination (adjusted OR, 0.88; 95 % CI 0.82–0.95). When vitamin D status was dichotomized, patients with 25OHD levels <20 ng/mL had an almost 3-fold risk of a non-home discharge destination (adjusted OR, 2.74; 95 % CI 1.23–6.14) compared to patients with 25OHD levels ≥20 ng/mL. Conclusions: Our results suggest that vitamin D status may be a modifiable risk factor for non-home discharge destination in surgical ICU patients. Future randomized, controlled trials are needed to determine whether vitamin D supplementation in surgical ICU patients can improve clinical outcomes such as the successful rate of discharge to home after critical illnes
