RESUMO
BACKGROUND: Early enteral nutrition (EN) is recommended for patients with critical illness to maintain intestinal immunity. However, the optimal timing of the commencement of EN remains unclear, particularly after cardiovascular surgery. OBJECTIVES: We herein focused on Persistent Inflammation, Immunosuppression, and Catabolism Syndrome (PICS) as a predisposing immunodeficiency and investigated its association with very early EN (VEEN) (<24 h) in patients who underwent cardiovascular surgery. METHODS: In this retrospective study, we used an administrative claims database with laboratory examinations between 2008 and 2021 to identify adult patients admitted to the intensive care unit after cardiovascular surgery. Patients who received EN the day after surgery were assigned to the EN <24 h group, whereas those who received EN on day 2 or day 3 were assigned to the control group. The primary outcome was a composite of the incidence of PICS and mortality on day 14 after surgery. We defined PICS as patients who were hospitalized for >14 day and meeting ≥2 of the following conditions: a lymphocyte count <800/µL, albumin <3.0 g/dL, and C-reactive protein >2.0 mg/dL. We compared the 2 groups using propensity score analysis. RESULTS: A propensity score matching generated 2082 pairs. The primary outcome was significantly lower in the EN <24 h group than in the control group on days 14 {risk difference [95% confidence interval (CI)]: -3.1% [-5.9%, -0.3%]} and 28 (risk difference [95% CI]: -2.1% [-3.7%, -0.4%]). Mortality did not significantly differ between the 2 groups. The length of hospital stay was significantly shorter in the EN <24 h group: the difference (95% CI) was -2.2 (-3.7, -0.7) d. CONCLUSIONS: Among patients who underwent cardiovascular surgery, VEEN provided on the day after surgery was associated with a lower incidence of PICS and a shorter length of hospital stay than EN provided 2 day or 3 day after surgery.
RESUMO
BACKGROUND & AIMS: Early enteral nutrition (EEN) potentially improves immune-related outcomes via the maintenance of intestinal immunity; however, the effects of EEN on clinical outcomes, including infectious complications, are controversial. Therefore, we herein investigated whether EEN affected persistent inflammation, immunosuppression, and catabolism syndrome (PICS), which represents the immunocompromised state after critical illness. METHODS: This retrospective cohort study utilized the administrative claims database of inpatients and laboratory findings. Patients admitted to and treated in the intensive care unit (ICU) for more than 3 consecutive days were included. The primary outcome, a composite of PICS or mortality on day 14 after admission, was compared between the EEN group, which received enteral nutrition (EN) on the first 3 days (day 0, 1, or 2), and the late enteral nutrition (LEN) group, which did not receive EN on the first 3 days, but then received EN on days 3 through 7, using a propensity score-matched analysis. Secondary outcomes included the composite outcome on day 28, in-hospital mortality, the Barthel index, and laboratory data. Patients who met at least two of the following conditions were diagnosed with PICS: CRP >2.0 mg/dL, albumin <3.0 g/dL, and a lymphocyte count <800/µL. RESULTS: A total of 7530 matched pairs were generated after propensity score matching. The primary outcome was significantly lower in the EEN group (risk difference -3.0%, 95% confidence interval (CI) -4.5 to -1.4%), whereas mortality did not significantly differ. The 28-day composite outcome was similar in the 2 groups (risk difference -1.5%, 95% CI -2.8% to -0.2%, no significant difference in mortality). There was no significant difference in in-hospital mortality between the EEN and LEN groups; however, the Barthel index at discharge was higher in the EEN group (the medians, 50 vs 45, P = 0.001). Laboratory data showed lower Albumin and CRP on day 14 in the EEN group, but no other significant differences. CONCLUSIONS: In patients admitted to the ICU, EEN was associated with a lower incidence of PICS on days 14 and 28, but was not associated with mortality. This positive association was not observed in sepsis, cardiac diseases, or gastrointestinal diseases.

INTRODUCTION: The association between sodium-glucose cotransporter-2 (SGLT2) inhibitors and the risk of urogenital infections remains controversial. This study aimed to investigate the association between SGLT2 inhibitors and the incidence of perineal soft tissue infections, including Fournier's gangrene (FG), genital bacterial infections, and urinary tract infections (UTIs), using administrative claims data in Japan. METHODS: In this retrospective cohort study, we utilized the JMDC Claims Database. The study included patients aged 18 years or older diagnosed with type 2 diabetes mellitus, identified by a diagnostic code, who received new prescriptions for SGLT2 inhibitors or dipeptidyl peptidase 4 (DPP-4) inhibitors between April 2014 and August 2020. Using one-to-one propensity score (PS) matching, we compared the incidence of perineal soft tissue infections, including FG, genital bacterial infection, and UTIs between groups treated with SGLT2 and DPP-4 inhibitors. Hazard ratios (HR) and their 95% confidence intervals (CI) were estimated using the Cox proportional hazards model. RESULTS: We identified 34,897 patients in the SGLT2 inhibitor group and 135,311 patients in the DPP-4 inhibitor group. After one-to-one PS matching, 31,665 pairs were generated. The mean age of the patients was 51 years, with approximately 70% being male. The use of SGLT2 inhibitors was associated with a decreased risk of UTI (HR 0.90, 95% CI 0.83-0.98) and an increased risk of genital bacterial infection (HR 1.23, 95% CI 1.03-1.46) compared to DPP-4 inhibitors. However, no significant association was observed with perineal soft tissue infection (HR 1.05, 95% CI 0.61-1.81). CONCLUSIONS: SGLT2 inhibitors were associated with a reduced risk of UTI and an increased risk of genital bacterial infection. They showed no significant association with perineal soft tissue infection when compared to DPP-4 inhibitors. Future research should explore broader demographics, focusing on the elderly and achieving gender balance, to gain a comprehensive understanding of infection risks.
RESUMO
INTRODUCTION: Days of antibiotic spectrum coverage (DASC), a novel metric for both antimicrobial volume and spectrum, was proposed to measure inpatient antimicrobial consumption in 2022. The DASC may better reflect efforts toward antimicrobial stewardship; however, no previous study has described the distribution of trends in DASC in hospitals or the association between the trend in DASC and days of therapy (DOT). This study assessed trends in antimicrobial consumption for inpatients at acute care hospitals in Japan using the DOT and DASC. METHODS: This retrospective observational study used the nationwide administrative inpatient claims database of Japanese acute care hospitals between 2014 and 2018. The prescriptions of all antibiotics were identified to calculate DOT/1000 patient-days, DASC/1000 patient-days, and DASC/DOT. We described the five-year trend in these metrics and examined the association between the trends in DOT and DASC. RESULTS: In total, 26,301,685 admissions from 634 hospitals were included. The DOT/1000 patient-days and DASC/1000 patient-days increased significantly by 6.1% and 5.6%, respectively. The DASC/DOT ratio did not change significantly (P = 0.35). Moreover, there was little correlation between DOT/1000 patient-days and DASC/DOT (R2 = 0.01). There was also little correlation between the five-year changes in DOT/1000 patient-days and those in DASC/DOT (R2 = 0.02). CONCLUSIONS: It may be difficult to assess trends in the antibiotic spectrum using DASC alone. However, the combination of DOT as a quantity indicator and DASC/DOT as a spectrum indicator may allow for a more appropriate evaluation of stewardship efforts.

BACKGROUND: Legionella pneumonia, a severe form of pneumonia, is caused by Legionella bacteria. The epidemiology of Legionnaires' disease in Japan, including seasonal trends, risk factors for severe disease, and fatality rates, is unclear. This study examined the epidemiology of Legionella pneumonia in Japan. METHODS: This retrospective cohort study included data of adult patients hospitalized for Legionella pneumonia (identified using the International Classification of Diseases, 10th revision code, A481) in the Japanese Diagnosis Procedure Combination inpatient database, from April 2011 to March 2021. We performed multivariable logistic regression analysis to explore the prognostic factors of in-hospital mortality. RESULTS: Of 7,370 enrolled hospitalized patients from 1,140 hospitals (male, 84.4%; aged >50 years, 87.9%), 469 (6.4%) died during hospitalization. The number of hospitalized patients increased yearly, from 658 in 2016 to 975 in 2020. Multivariable logistic regression analysis revealed that higher in-hospital mortality was associated with older age, male sex, lower body mass index, worsened level of consciousness, comorbidities (congestive heart failure, chronic renal diseases, and metastasis), hospitalization from November to May, and ambulance use. However, lower in-hospital mortality was associated with comorbidity (liver diseases), hospitalization after 2013, and hospitalization in hospitals with higher case volume. CONCLUSION: The characterized epidemiology of Legionella pneumonia in Japan revealed a high mortality rate of 6.4%. To the best of our knowledge, this is the first study to demonstrate a higher mortality rate in winter and in patients with congestive heart failure and metastasis. Further research is needed to understand the complex interplay between the prognostic factors of Legionella pneumonia.

There have been few reports on the diagnostic performance of soluble interleukin-2 receptor (sIL-2R) for lymphoma. A cross-sectional study was conducted at a university hospital; all patients who were admitted to the Division of General Internal Medicine and underwent serum sIL-2R testing were included. Patients were divided into two groups based on the presence of fever (≥ 38.0 °C). Among 602 patients, 421 had fever and 76 were diagnosed with lymphoma (48 of the 76 were in the febrile group). In all patients, the area under the receiver operating characteristic curve (AUROC) of sIL-2R for the diagnosis of lymphoma was 0.81 [95% confidence interval (CI), 0.75-0.87]. The AUROC was significantly higher in the febrile group (0.88; 95% CI, 0.81-0.94) than in the afebrile group (0.75; 95% CI, 0.65-0.85). In the febrile group, the sensitivity and specificity were 81.2% and 82.3%, respectively, with an optimal cutoff value of 3,250 U/mL. In the afebrile group, they were 89.3% and 54.9%, respectively, with a cutoff value of 868 U/mL. Serum sIL-2R showed high performance as an adjunctive diagnostic marker for lymphoma, particularly among febrile patients. Different cutoff values should be used for patients with and without fever to maximize diagnostic performance.

BACKGROUND: Whether GPT-4, the conversational artificial intelligence, can accurately diagnose and triage health conditions and whether it presents racial and ethnic biases in its decisions remain unclear. OBJECTIVE: We aim to assess the accuracy of GPT-4 in the diagnosis and triage of health conditions and whether its performance varies by patient race and ethnicity. METHODS: We compared the performance of GPT-4 and physicians, using 45 typical clinical vignettes, each with a correct diagnosis and triage level, in February and March 2023. For each of the 45 clinical vignettes, GPT-4 and 3 board-certified physicians provided the most likely primary diagnosis and triage level (emergency, nonemergency, or self-care). Independent reviewers evaluated the diagnoses as "correct" or "incorrect." Physician diagnosis was defined as the consensus of the 3 physicians. We evaluated whether the performance of GPT-4 varies by patient race and ethnicity, by adding the information on patient race and ethnicity to the clinical vignettes. RESULTS: The accuracy of diagnosis was comparable between GPT-4 and physicians (the percentage of correct diagnosis was 97.8% (44/45; 95% CI 88.2%-99.9%) for GPT-4 and 91.1% (41/45; 95% CI 78.8%-97.5%) for physicians; P=.38). GPT-4 provided appropriate reasoning for 97.8% (44/45) of the vignettes. The appropriateness of triage was comparable between GPT-4 and physicians (GPT-4: 30/45, 66.7%; 95% CI 51.0%-80.0%; physicians: 30/45, 66.7%; 95% CI 51.0%-80.0%; P=.99). The performance of GPT-4 in diagnosing health conditions did not vary among different races and ethnicities (Black, White, Asian, and Hispanic), with an accuracy of 100% (95% CI 78.2%-100%). P values, compared to the GPT-4 output without incorporating race and ethnicity information, were all .99. The accuracy of triage was not significantly different even if patients' race and ethnicity information was added. The accuracy of triage was 62.2% (95% CI 46.5%-76.2%; P=.50) for Black patients; 66.7% (95% CI 51.0%-80.0%; P=.99) for White patients; 66.7% (95% CI 51.0%-80.0%; P=.99) for Asian patients, and 62.2% (95% CI 46.5%-76.2%; P=.69) for Hispanic patients. P values were calculated by comparing the outputs with and without conditioning on race and ethnicity. CONCLUSIONS: GPT-4's ability to diagnose and triage typical clinical vignettes was comparable to that of board-certified physicians. The performance of GPT-4 did not vary by patient race and ethnicity. These findings should be informative for health systems looking to introduce conversational artificial intelligence to improve the efficiency of patient diagnosis and triage.
RESUMO
Objectives: The purpose of this research is to describe the social demographics and chief complaints of users of a free medical consultation application in Ibaraki Prefecture, where a free medical consultation application was released. Methods: The present study included users of a telehealth application in Ibaraki Prefecture between April 9 and May 17, 2020, during the state of emergency. User background characteristics were descriptively analyzed to clarify individual factors with the potential to act as barriers to equally using innovative solutions. Additionally, the age and consultation time distribution by sex were examined for those who used the application for COVID-19 and non-COVID-19 issues. Results: Most of the participants were in their thirties. Moreover, 72% were female, with most being in their thirties (86%) and the least being in their sixties (45%). The number of consultations was concentrated between 6 p.m. and 10 p.m., with the least between 1 a.m. and 5 a.m. The telehealth application users were mainly females in their thirties and forties. Conclusions: To prevent the widening of health disparities due to the rapid introduction of telehealth, further research is required to identify why the use of the application did not spread beyond the aforementioned user groups.
RESUMO
BACKGROUND: Antimicrobial stewardship in dentistry and antibiotic prophylaxis for tooth extraction have been areas of concern in Japan, with limited research available. METHODS: This cross-sectional study utilized the regional health insurance claims database in Japan to examine antibiotic prescription trends by dentists, including antibiotic regimens, timing of prescription, and days of supply for prophylactic antibiotic use during tooth extraction. Antibiotic prophylaxis for patients with prosthetic heart valves was also investigated. FINDINGS: Antibiotic prescriptions by dentists decreased by 7% in 2019 compared to those in 2015, with third-generation cephalosporins still accounting for 48.5% in 2019. Amoxicillin prescription increased 3.9 times in 2019, although it only accounted for 8.4% of all antibiotic prescriptions. In 2019, amoxicillin was prescribed for 17.1% of all prophylactic antibiotics associated with tooth extraction, and 80% of prophylactic antibiotics were prescribed for 3 days or more, with 85% prescribed on the day of the procedure. However, only 60-70% of patients with prosthetic heart valves received antibiotic prophylaxis. INTERPRETATION: Despite the increasing trend after the implementation of the National Action Plan on antimicrobial resistance, the proportion of amoxicillin prescriptions in dentistry remains low. Antimicrobial stewardship issues related to long-term prescription and timing of administration of prophylactic antibiotics for tooth extraction should be addressed. Dentists must recognize the risks associated with high-risk patients with prosthetic heart valves who require antibiotic prophylaxis, and physicians providing valve replacement therapy should inform patients of the requirement for prophylaxis before invasive dental procedures.

Persistent inflammation, immunosuppression, and catabolism syndrome (PICS) is a serious condition after critical care. We examined the efficacy of antithrombin, which may attenuate coagulopathy with the control of inflammation, for PICS among patients with sepsis-induced disseminated intravascular coagulation (DIC). The present study used the inpatient claims database with laboratory findings to identify patients admitted to intensive care units and diagnosed with sepsis and DIC. A composite of the incidence of PICS on day 14 or 14-day mortality as the primary outcome was compared between the antithrombin and control groups using a propensity-score-matched analysis. Secondary outcomes were the incidence of PICS on day 28, 28-day mortality, and in-hospital mortality. A total of 324 well-balanced matched pairs were generated from 1622 patients. The primary outcome did not differ between the antithrombin and control groups (63.9% vs. 68.2%, respectively, p = 0.245). However, the incidences of 28-day and in-hospital mortality were significantly lower in the antithrombin group (16.0% vs. 23.5% and 24.4% vs. 35.8%, respectively). Similar results were obtained in a sensitivity analysis using overlap weighting. Antithrombin did not reduce the occurrence of PICS on day 14 in patients with sepsis-induced DIC; however, it was associated with a better mid-term (day 28) prognosis.

INTRODUCTION: Post-intensive care syndrome (PICS) is an emerging problem in critically ill patients and the prevalence and risk factors are unclear in patients with severe coronavirus disease 2019 (COVID-19). This multicenter prospective observational study aimed to investigate the prevalence and risk factors of PICS in ventilated patients with COVID-19 after ICU discharge. METHODS: Questionnaires were administered twice in surviving patients with COVID-19 who had required mechanical ventilation, concerning Barthel Index, Short-Memory Questionnaire, and Hospital Anxiety and Depression Scale scores. The risk factors for PICS were examined using a multivariate logistic regression analysis. RESULTS: The first and second PICS surveys were obtained at 5.5 and 13.5 months (mean) after ICU discharge, with 251 and 209 patients completing the questionnaires and with a prevalence of PICS of 58.6% and 60.8%, respectively, along with the highest percentages of cognitive impairment. Delirium (with an odds ratio of (OR) 2.34, 95% CI 1.1-4.9, and p = 0.03) and the duration of mechanical ventilation (with an OR of 1.29, 95% CI 1.05-1.58, and p = 0.02) were independently identified as the risk factors for PICS in the first PICS survey. CONCLUSION: Approximately 60% of the ventilated patients with COVID-19 experienced persistent PICS, especially delirium, and required longer mechanical ventilation.
RESUMO
BACKGROUND: Disseminated infections of Mycolicibacter arupensis, a slowly growing nontuberculous mycobacteria (NTM) which causes synovitis, osteomyelitis, or pulmonary infections have rarely been reported. We report a case of disseminated M. arupensis and Mycobacterium avium co-infection in a patient with anti-interferon (IFN)-γ neutralizing autoantibody-associated immunodeficiency syndrome. CASE PRESENTATION: A 68-year-old Japanese male without human immunodeficiency virus infection was referred with complaints of persistent low-grade fever, arthralgia of the upper limbs, and weight loss of 10 kg. Cervical and mediastinal lymphadenopathies as well as a nodular opacity in the right lung were detected, and biopsy specimens of the cervical lymph node yielded M. arupensis without evidence of malignant cells. M. arupensis was also detected in sputum and peripheral blood. Computed tomography (CT) revealed deterioration of the right supraclavicular lymphadenopathy with internal necrosis and multiple low-density splenic lesions. Bone marrow and aspirates from the cervical lymph node collected at initiation of treatment yielded M. avium. The presence of anti-IFN-γ neutralizing autoantibodies was detected, leading to a diagnosis of co-infection of M. arupensis and M. avium with anti-IFN-γ neutralizing autoantibody-associated immunodeficiency syndrome. Post initiation of treatment with clarithromycin, ethambutol, and rifabutin, his fever declined, and his polyarthritis resolved. He developed disseminated varicella zoster during treatment; however, a follow-up CT scan six months after treatment revealed improvement of the lymphadenopathies, consolidation in the right lung, and splenic lesions. CONCLUSION: This is the first report of disseminated M. arupensis and M. avium co-infection in a patient with anti-IFN-γ neutralizing autoantibody-associated immunodeficiency syndrome.

BACKGROUND: This is the first report from a multicenter prospective cohort study of colorectal neuroendocrine tumor (NET), the C-NET STUDY, conducted to assess the long-term outcomes of the enrolled patients. This report aimed to elucidate the clinicopathological features of the enrolled patients and lesions. METHODS: Colorectal NET patients aged 20-74 years were consecutively enrolled and followed up at 50 institutions. The baseline characteristics and clinicopathological findings at enrollment and treatment were assessed. RESULTS: A total of 495 patients with 500 colorectal NETs were included. The median patient age was 54 years, and 85.3% were asymptomatic. The most frequent lesion location was the lower rectum (88.0%); 99.4% of the lesions were clinically diagnosed to be devoid of metastatic findings, and 95.4% were treated with endoscopic resection. Lesions < 10 mm comprised 87.0% of the total, 96.6% had not invaded the muscularis propria, and 92.6% were classified as WHO NET grade 1. Positive lymphovascular involvement was found in 29.2% of the lesions. Its prevalence was high even in small NETs with immunohistochemical/special staining for pathological assessment (26.4% and 40.9% in lesions sized < 5 mm and 5-9 mm, respectively). Among 70 patients who underwent radical surgery primarily or secondarily, 18 showed positive lymph node metastasis. CONCLUSIONS: The characteristics of real-world colorectal NET patients and lesions are elucidated. The high positivity of lymphovascular involvement in small NETs highlights the necessity of assessing the clinical significance of positive lymphovascular involvement based on long-term outcomes, which will be examined in later stages of the C-NET STUDY. TRIAL REGISTRATION NUMBER: UMIN000025215.

INTRODUCTION: Rapid diagnostic tests have been developed recently for rapid species or resistance genes identification, offering the potential to improve the selection of appropriate antibiotics. The newly developed FilmArray Blood Culture Identification 2 (BCID2) panel, which can identify more species and resistance genes, such as extended-spectrum beta-lactamase, is expected to make an impact on antimicrobial practice. METHODS: The consecutive 50 inpatients with Gram-negative bacilli bacteremia were enrolled to this retrospective single-center study. In addition to the existing FilmArray Blood Culture Identification (BCID) panel, we have implemented BCID2 panel for positive blood culture. The sensitivity and specificity of BCID and BCID2 panel were respectively calculated, and a simulation study of time to effective, optimal and de-escalation therapy was performed based on BCID or BCID2 result. RESULTS: A total of 52 Gram-negative organisms in 50 patients were identified from blood cultures. Of these, 45 (87%) organisms were detected by BCID2 panel, which was more than BCID panel (41 organisms, 79%). BCID2 panel detected 5 CTX-M genes, which were concordant with conventional method. The time to effective therapy did not differ between BCID arm and BCID2 arm; however, the median time to optimal therapy (34 h in BCID arm and 26 h in BCID2 arm, P = 0.0007) and the median time to de-escalation therapy (42 h in BCID arm and 22 h in BCID2 arm, P = 0.0005) were significantly shortened. CONCLUSIONS: This simulation study of BCID2 panel showed high sensitivity and specificity, and the potential impact on shortening the time to optimal and de-escalation therapy.

This study aimed to develop and validate an emergency nursing-care patient satisfaction scale to measure patient satisfaction with emergency room (ER) nursing. Patient satisfaction scales for ER nursing have been validated without considering the perspectives of the healthcare system or cultural background of the country. Moreover, although nursing care is changing with COVID-19, no scale has been specifically designed to assess patient satisfaction with ER nursing. The study population included patients who visited five ERs in Japan (March to December 2021) (n = 135). The rating scales were provided to patients who visited the ER and gave consent, and the patients were asked to reply. In the process of validating the scale, exploratory and confirmatory factor analyses of the construct and criterion validity were conducted. The confirmatory factor analysis results showed a factorial structure consisting of four factors. The domain and summary scores demonstrated good-to-excellent internal reliability (Cronbach's range = 0.81-0.89). This patient satisfaction scale was designed and validated from the perspective of the Japanese healthcare system and cultural backgrounds. This scale may be useful for developing assessments and interventions to improve patient satisfaction with ER nursing.
RESUMO
AIM: This study aimed to evaluate whether nurse-initiated sedation management could provide more appropriate sedation compared to usual care in a Japanese intensive care unit (ICU). METHODS: We conducted a single-center, prospective observational study before and after implementing nurse-initiated sedation using instruction sheets. Patients who had been admitted to a general adult ICU were enrolled. Before our ICU started nurse-initiated sedation (pre-implementation care), adjustment of sedatives and analgesics was performed only by a physician's written or verbal order; however, after implementing nurse-initiated sedation, nurses titrated drugs using instruction sheets. The primary outcome was the efficacy of nurse-initiated sedation, evaluated by the proportion achieving the target Richmond Agitation-Sedation Scale (RASS) score. The analgesic status evaluated by Critical-Care Pain Observation Tool (CPOT), days of delirium, ventilator days, ICU mortality and hospital mortality were also evaluated. RESULTS: The study examined 30 patients in the pre-implementation care phase and 30 patients in the nurse-initiated sedation phase. The proportions achieving the target RASS were 68% in the nurse-initiated sedation group and 42% in the pre-implementation care group (mean difference, 25%; 95% confidence interval, 13.4%-37.5%; P <.001). Almost all measured CPOT were within the range of 0-3 during both phases. Days of delirium, ventilator days, ICU survival, and hospital survival did not differ significantly between the two groups. CONCLUSIONS: Nurse-initiated sedation management achieved a significantly higher degree of target sedation status and was incorporated as part of the care in our ICU. It is a safe approach in countries, such as Japan, where sedation protocols are not widely used.

BACKGROUND: Optimal nutrition therapy has not yet been established for the acute phase of severe coronavirus disease 2019 (COVID-19) infection. OBJECTIVES: We aimed to examine the effects of nutrition delivery in the acute phase on mortality and the long-term outcomes of post-intensive care syndrome (PICS). METHODS: A multicenter prospective study was conducted on adult patients with COVID-19 infection requiring mechanical ventilation during an intensive care unit (ICU) stay. Daily total energy (kcal/kg) and protein (g/kg) deliveries in the first week of the ICU stay were calculated. The questionnaire for PICS evaluation was mailed within a median of 6 mo after hospital discharge. The primary outcome was in-hospital mortality, and secondary outcomes were the PICS components of physical impairment, cognitive dysfunction, and mental illness. RESULTS: Among 414 eligible patients, 297 who received mechanical ventilation for 7 d or longer were examined. PICS was evaluated in 175 patients among them. High protein delivery on days 4-7 correlated with a low in-hospital mortality rate. In contrast, high protein delivery on days 1-3 correlated with physical impairment. A multivariate logistic regression analysis adjusted for age, sex, BMI, and severity revealed that average energy and protein deliveries on days 4-7 correlated with decreased in-hospital mortality (OR: 0.94; 95% CI: 0.89, 0.99; P = 0.013 and OR: 0.40; 95% CI: 0.17, 0.93; P = 0.031, respectively). Nutrition delivery did not correlate with PICS outcomes after adjustments. In the multivariate regression using a restricted cubic spline model, in-hospital mortality monotonically decreased with increases in average nutrition delivery on days 4-7. CONCLUSIONS: In patents with COVID-19 on mechanical ventilation for ≥7 d, nutrition delivery in the late period of the acute phase was monotonically associated with a decrease in in-hospital mortality. Adequate protein delivery is needed on days 4-7.This trial was registered at https://www.umin.ac.jp as UMIN000041276.
