Background Optimal nutrition therapy has not yet been established for the acute phase of severe coronavirus disease 2019 (COVID-19) infection. Objectives To examine the effects of nutrition delivery in the acute phase on the mortality and 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 the PICS evaluation was mailed within a median of 6 months after hospital discharge. The primary outcome was in-hospital mortality, and secondary outcomes were PICS components of physical, cognitive dysfunction and mental illness. Results Among 414 eligible patients, 297 who received mechanical ventilation for 7 days 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, body mass index, and severity revealed that average energy and protein deliveries on days 4–7 correlated with decreased in-hospital mortality; odds ratio 0.94 (95%CI 0.89,0.99) (P = 0.013) and 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 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 ≥ 7 days, 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.

Background The Acute Physiology and Chronic Health Evaluation (APACHE) III-j model is widely used to predict mortality in Japanese intensive care units (ICUs). Although the model’s discrimination is excellent, its calibration is poor. APACHE III-j overestimates the risk of death, making its evaluation of healthcare quality inaccurate. This study aimed to improve the calibration of the model and develop a Japan Risk of Death (JROD) model for benchmarking purposes. Methods A retrospective analysis was conducted using a national clinical registry of ICU patients in Japan. Adult patients admitted to an ICU between April 1, 2018, and March 31, 2019, were included. The APACHE III-j model was recalibrated with the following models: Model 1, predicting mortality with an offset variable for the linear predictor of the APACHE III-j model using a generalized linear model; model 2, predicting mortality with the linear predictor of the APACHE III-j model using a generalized linear model; and model 3, predicting mortality with the linear predictor of the APACHE III-j model using a hierarchical generalized additive model. Model performance was assessed with the area under the receiver operating characteristic curve (AUROC), the Brier score, and the modified Hosmer–Lemeshow test. To confirm model applicability to evaluating quality of care, funnel plots of the standardized mortality ratio and exponentially weighted moving average (EWMA) charts for mortality were drawn. Results In total, 33,557 patients from 44 ICUs were included in the study population. ICU mortality was 3.8%, and hospital mortality was 8.1%. The AUROC, Brier score, and modified Hosmer–Lemeshow p value of the original model and models 1, 2, and 3 were 0.915, 0.062, and < .001; 0.915, 0.047, and < .001; 0.915, 0.047, and .002; and 0.917, 0.047, and .84, respectively. Except for model 3, the funnel plots showed overdispersion. The validity of the EWMA charts for the recalibrated models was determined by visual inspection. Conclusions Model 3 showed good performance and can be adopted as the JROD model for monitoring quality of care in an ICU, although further investigation of the clinical validity of outlier detection is required. This update method may also be useful in other settings.

Emergency physicians perform endotracheal intubations for patients with COVID-19. However, the trends in the intubation for COVID-19 patients in terms of success rate, complications, personal protective equipment (PPE) information, barrier enclosure use, and its transition have not been established. We conducted a retrospective study of COVID-19 cases that required tracheal intubation at four hospitals in the Tokyo metropolitan area between January 2020 and August 2021. The overall intubation success rate, operator experience, and infection control methods were investigated. We then compared the early and late phases of the pandemic for a period of 8 months each. A total of 211 cases met the inclusion criteria, and 133 were eligible for analysis. The intubation success rate increased from 85% to 94% from early to late phase, although the percentage of intubations performed by emergency medicine residents increased significantly in the late phase (p = 0.03). The percentage of light PPE use significantly increased from 65% to 91% from early to late phase (p < 0.01), whereas the percentage of barrier enclosure use significantly decreased from 26% to 0% (p < 0.01). Furthermore, the infection prevention methods during intubation became more simplified from early to late phase.

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.

Since the start of the coronavirus disease 2019 (COVID-19) pandemic, it has remained unknown whether conventional risk prediction tools used in intensive care units are applicable to patients with COVID-19. Therefore, we assessed the performance of established risk prediction models using the Japanese Intensive Care database. Discrimination and calibration of the models were poor. Revised risk prediction models are needed to assess the clinical severity of COVID-19 patients and monitor healthcare quality in ICUs overwhelmed by patients with COVID-19.

Background: Patients with COVID-19 may require emergency tracheal intubation for mechanical ventilation by emergency physicians. However, the success rate, complications, operator safety, and issues around personal protective equipment (PPE) and barrier enclosure use are not known in this context.Methods: This was a retrospective study of data for adult patients with COVID-19 who underwent endotracheal intubation performed by emergency physicians at four hospitals in the Tokyo Metropolitan Area between January 2020 and September 2020. Patient characteristics, intubation-related factors, and intubation success and complications rates were obtained. Two analyses were then performed. In analysis 1, the intubation success rate in patients was compared among four groups using different types of PPE. In analysis 2, patients were compared by those intubated with or without barrier enclosure.Results: In total, 46 patients met the inclusion criteria, of whom 85% were successfully intubated at the first attempt, 27% experienced hypotension, and 27% experienced hypoxia. No muscle relaxants were used in 8.7% and the Macintosh blade was used in 37%. The four PPE types and the intubation confirmation methods varied considerably, but all met the WHO recommendations. A barrier enclosure device was used in 26%, with a success rate of approximately 80% irrespective of its use.Conclusions: The success rate at the first attempt of intubation was relatively high, albeit with a moderately high complication rate. All PPE types were safe, including when barrier enclosures were used. Success was not affected by using barrier enclosures.

Introduction: In nutrition therapy for critically ill patients, it is recommended that enteral nutrition (EN) formula be changed every 8 h to avoid bacterial contamination. However, it remains unknown whether long-term administration of EN formula from a sterile sealed bag without changing the formula can cause bacterial contamination. This study investigates the association between bacterial contamination and administration of liquid EN formula from a sterile sealed bag without changing the formula for 24 h. Methods: This single-center, prospective, interventional study included patients aged ≥20 years who were admitted to an intensive care unit and received 24-h continuous liquid EN formula from a sterile sealed bag. A 3-mL sample of the formula was collected from each bag every 4 h for bacterial culture. The primary outcome was the detection of bacterial colonies. Results: A total of 630 specimens from 30 patients were cultured. No bacterial colonies were detected. Conclusion: There was no association between bacterial contamination and continuous administration of liquid EN formula from a sterile sealed bag for 24 h. Therefore, this study recommends continuous administration of EN from a sterile sealed bag for 24 h without changing the EN formula under those limited conditions.

Intensive care unit survivors experience prolonged physical impairments, cognitive impairments, and mental health problems, commonly referred to as post-intensive care syndrome (PICS). Previous studies reported the prevalence, assessment, and prevention of PICS, including the ABCDEF bundle approach. Although the management of PICS has been advanced, the outbreak of coronavirus disease 2019 (COVID-19) posed an additional challenge to PICS. The prevalence of PICS after COVID-19 extensively varied with 28–87% of cases pertaining to physical impairments, 20–57% pertaining to cognitive impairments, and 6–60% pertaining to mental health problems after 1–6 months after discharge. Each component of the ABCDEF bundle is not sufficiently provided from 16% to 52% owing to the highly transmissible nature of the virus. However, new data are emerging about analgesia, sedation, delirium care, nursing care, early mobilization, nutrition, and family support. In this review, we summarize the recent data on PICS and its new challenge in PICS after COVID-19 infection.

Purpose The Japanese Intensive care PAtient Database (JIPAD) was established to construct a high-quality Japanese intensive care unit (ICU) database. Materials and methods A data collection structure for consecutive ICU admissions in adults (≥16 years) and children (≤15 years) has been established in Japan since 2014. We herein report a current summary of the data in JIPAD for admissions between April 2015 and March 2017. Results There were 21,617 ICU admissions from 21 ICUs (217 beds) including 8416 (38.9%) for postoperative or procedural monitoring, defined as adult admissions following elective surgery or for procedures and discharged alive within 24 h, 11,755 (54.4%) critically ill adults other than monitoring, and 1446 (6.7%) children. The standardized mortality ratios (SMRs) based on the Acute Physiology and Chronic Health Evaluation (APACHE) III-j, APACHE II, and Simplified Acute Physiology Score II scores in adults ranged from 0.387 to 0.534, whereas the SMR based on the Paediatric Index of Mortality 2 in children was 0.867. Conclusion The data revealed that the SMRs based on general severity scores in adults were low because of high proportions of elective and monitoring admission. The development of a new mortality prediction model for Japanese ICU patients is needed.

Background Information on epidemiology of prolonged mechanical ventilation (PMV) patients in the acute care setting in Japan is totally lacking. We aimed to investigate clinical features, impact, and long-term outcomes of PMV patients. Methods This was a retrospective observational study conducted in a tertiary care hospital. Adult patients who were admitted to our intensive care unit (ICU) from April 2009 to March 2014 and required mechanical ventilation (MV) for ≥ 2 days were included. PMV was defined as having MV for ≥ 21 consecutive days. Results Among 1282 MV patients, 93 (7.3%) required PMV, and median duration of MV was 37.0 days. Compared with the non-PMV patients, PMV patients had longer total ICU and high care unit (HCU) stay (34.0 vs. 7.0 days, p p p Conclusion In this investigation, 7.3% of the patients with MV required PMV. Most PMV patients were liberated from MV during hospitalization, while occupying critical care beds for an extended period. A nationwide survey is required to further elucidate the overall picture of PMV patients and to discuss whether specialized weaning centers to treat PMV patients are required in Japan.

Expanding elderly populations are a major social challenge in advanced countries worldwide and have led to a rapid increase in the number of elderly patients in intensive care units (ICUs). Innovative advances in medical technology have enabled lifesaving of patients in ICUs, but there remain various problems to improve their long-term prognoses. Post-intensive care syndrome (PICS) refers to physical, cognition, and mental impairments that occur during ICU stay, after ICU discharge or hospital discharge, as well as the long-term prognosis of ICU patients. Its concept also applies to pediatric patients (PICS-p) and the mental status of their family (PICS-F). Intensive care unit-acquired weakness, a syndrome characterized by acute symmetrical limb muscle weakness after ICU admission, belongs to physical impairments in three domains of PICS. Prevention of PICS requires performance of the ABCDEFGH bundle, which incorporates the prevention of delirium, early rehabilitation, family intervention, and follow-up from the time of ICU admission to the time of discharge. Diary, nutrition, nursing care, and environmental management for healing are also important in the prevention of PICS. This review outlines the pathophysiology, prevention, and future directions of PICS.

The Japanese Clinical Practice Guidelines for Management of Sepsis and Septic Shock 2020 (J-SSCG 2020), a Japanese-specific set of clinical practice guidelines for sepsis and septic shock created as revised from J-SSCG 2016 jointly by the Japanese Society of Intensive Care Medicine and the Japanese Association for Acute Medicine, was first released in September 2020 and published in February 2021. An English-language version of these guidelines was created based on the contents of the original Japanese-language version. The purpose of this guideline is to assist medical staff in making appropriate decisions to improve the prognosis of patients undergoing treatment for sepsis and septic shock. We aimed to provide high-quality guidelines that are easy to use and understand for specialists, general clinicians, and multidisciplinary medical professionals. J-SSCG 2016 took up new subjects that were not present in SSCG 2016 (e.g., ICU-acquired weakness [ICU-AW], post-intensive care syndrome [PICS], and body temperature management). The J-SSCG 2020 covered a total of 22 areas with four additional new areas (patient- and family-centered care, sepsis treatment system, neuro-intensive treatment, and stress ulcers). A total of 118 important clinical issues (clinical questions, CQs) were extracted regardless of the presence or absence of evidence. These CQs also include those that have been given particular focus within Japan. This is a large-scale guideline covering multiple fields; thus, in addition to the 25 committee members, we had the participation and support of a total of 226 members who are professionals (physicians, nurses, physiotherapists, clinical engineers, and pharmacists) and medical workers with a history of sepsis or critical illness. The GRADE method was adopted for making recommendations, and the modified Delphi method was used to determine recommendations by voting from all committee members.As a result, 79 GRADE-based recommendations, 5 Good Practice Statements (GPS), 18 expert consensuses, 27 answers to background questions (BQs), and summaries of definitions and diagnosis of sepsis were created as responses to 118 CQs. We also incorporated visual information for each CQ according to the time course of treatment, and we will also distribute this as an app. The J-SSCG 2020 is expected to be widely used as a useful bedside guideline in the field of sepsis treatment both in Japan and overseas involving multiple disciplines., other authors: Satoru Hashimoto,Daisuke Hasegawa,Junji Hatakeyama,Naoki Hara,Naoki Higashibeppu,Nana Furushima,Hirotaka Furusono,Yujiro Matsuishi,Tasuku Matsuyama,Yusuke Minematsu,Ryoichi Miyashita,Yuji Miyatake,Megumi Moriyasu,Toru Yamada,Hiroyuki Yamada,Ryo Yamamoto,Takeshi Yoshida,Yuhei Yoshida,Jumpei Yoshimura,Ryuichi Yotsumoto,Hiroshi Yonekura,Takeshi Wada,Eizo Watanabe,Makoto Aoki,Hideki Asai,Takakuni Abe,Yutaka Igarashi,Naoya Iguchi,Masami Ishikawa,Go Ishimaru,Shutaro Isokawa,Ryuta Itakura,Hisashi Imahase,Haruki Imura,Takashi Irinoda,Kenji Uehara,Noritaka Ushio,Takeshi Umegaki,Yuko Egawa,Yuki Enomoto,Kohei Ota,Yoshifumi Ohchi,Takanori Ohno,Hiroyuki Ohbe,Kazuyuki Oka,Nobunaga Okada,Yohei Okada,Hiromu Okano,Jun Okamoto,Hiroshi Okuda,Takayuki Ogura,Yu Onodera,Yuhta Oyama,Motoshi Kainuma,Eisuke Kako,Masahiro Kashiura,Hiromi Kato,Akihiro Kanaya,Tadashi Kaneko,Keita Kanehata,Ken-ichi Kano,Hiroyuki Kawano,Kazuya Kikutani,Hitoshi Kikuchi,Takahiro Kido,Sho Kimura,Hiroyuki Koami,Daisuke Kobashi,Iwao Saiki,Masahito Sakai,Ayaka Sakamoto,Tetsuya Sato,Yasuhiro Shiga,Manabu Shimoto,Shinya Shimoyama,Tomohisa Shoko,Yoh Sugawara,Atsunori Sugita,Satoshi Suzuki,Yuji Suzuki,Tomohiro Suhara,Kenji Sonota,Shuhei Takauji,Kohei Takashima,Sho Takahashi,Yoko Takahashi,Jun Takeshita,Yuuki Tanaka,Akihito Tampo,Taichiro Tsunoyama,Kenichi Tetsuhara,Kentaro Tokunaga,Yoshihiro Tomioka,Kentaro Tomita,Naoki Tominaga,Mitsunobu Toyosaki,Yukitoshi Toyoda,Hiromichi Naito,Isao Nagata,Tadashi Nagato,Yoshimi Nakamura,Yuki Nakamori,Isao Nahara,Hiromu Naraba,Chihiro Narita,Norihiro Nishioka,Tomoya Nishimura,Kei Nishiyama,Tomohisa Nomura,Taiki Haga,Yoshihiro Hagiwara,Katsuhiko Hashimoto,Takeshi Hatachi,Toshiaki Hamasaki,Takuya Hayashi,Minoru Hayashi,Atsuki Hayamizu,Go Haraguchi,Yohei Hirano,Ryo Fujii,Motoki Fujita,Naoyuki Fujimura,Hiraku Funakoshi,Masahito Horiguchi,Jun Maki,Naohisa Masunaga,Yosuke Matsumura,Takuya Mayumi,Keisuke Minami,Yuya Miyazaki,Kazuyuki Miyamoto,Teppei Murata,Machi Yanai,Takao Yano,Kohei Yamada,Naoki Yamada,Tomonori Yamamoto,Shodai Yoshihiro,Hiroshi Tanaka,Osamu Nishida, Guidelines

Introduction Postintensive care syndrome (PICS) is defined as a new or worsening impairment in cognition, mental health and physical function after critical illness. There is little evidence regarding treatment of patients with PICS; new directions for effective treatment strategies are urgently needed. Early physiotherapy may prevent or reverse some physical impairments in patients with PICS, but no systematic reviews have investigated the effectiveness of early rehabilitation on PICS-related outcomes. The purpose of this systematic review is to evaluate whether early rehabilitative interventions in critically ill patients can prevent PICS and decrease mortality. Methods We will conduct a systematic review and meta-analysis of early rehabilitation for the prevention of PICS in critically ill adults. We will search PubMed, EMBASE and the Cochrane Central Register of Controlled Trials for published randomised controlled trials. We will screen search results and assess study selection, data extraction and risk of bias in duplicate, resolving disagreements by consensus. We will pool data from clinically homogeneous studies using a random-effects meta-analysis; assess heterogeneity of effects using the χ 2 test of homogeneity; and quantify any observed heterogeneity using the I 2 statistic. We will use the Grading of Recommendations Assessment, Development and Evaluation approach to rate the quality of evidence. Discussion This systematic review will present evidence on the prevention of PICS in critically ill patients with early rehabilitation. Ethics Ethics approval is not required. Dissemination The results will be disseminated via peer-reviewed journal publication, conference presentation(s) and publications for patient information. Trial registration number CRD42016039759.

Background and purpose The Japanese Clinical Practice Guidelines for Management of Sepsis and Septic Shock 2016 (J-SSCG 2016), a Japanese-specific set of clinical practice guidelines for sepsis and septic shock created jointly by the Japanese Society of Intensive Care Medicine and the Japanese Association for Acute Medicine, was first released in February 2017 and published in the Journal of JSICM, [2017; Volume 24 (supplement 2)] 10.3918/jsicm.24S0001 and Journal of Japanese Association for Acute Medicine [2017; Volume 28, (supplement 1)] http://onlinelibrary.wiley.com/doi/10.1002/jja2.2017.28.issue-S1/issuetoc. This abridged English edition of the J-SSCG 2016 was produced with permission from the Japanese Association of Acute Medicine and the Japanese Society for Intensive Care Medicine. Methods Members of the Japanese Society of Intensive Care Medicine and the Japanese Association for Acute Medicine were selected and organized into 19 committee members and 52 working group members. The guidelines were prepared in accordance with the Medical Information Network Distribution Service (Minds) creation procedures. The Academic Guidelines Promotion Team was organized to oversee and provide academic support to the respective activities allocated to each Guideline Creation Team. To improve quality assurance and workflow transparency, a mutual peer review system was established, and discussions within each team were open to the public. Public comments were collected once after the initial formulation of a clinical question (CQ) and twice during the review of the final draft. Recommendations were determined to have been adopted after obtaining support from a two-thirds (> 66.6%) majority vote of each of the 19 committee members. Results A total of 87 CQs were selected among 19 clinical areas, including pediatric topics and several other important areas not covered in the first edition of the Japanese guidelines (J-SSCG 2012). The approval rate obtained through committee voting, in addition to ratings of the strengths of the recommendation, and its supporting evidence were also added to each recommendation statement. We conducted meta-analyses for 29 CQs. Thirty-seven CQs contained recommendations in the form of an expert consensus due to insufficient evidence. No recommendations were provided for five CQs. Conclusions Based on the evidence gathered, we were able to formulate Japanese-specific clinical practice guidelines that are tailored to the Japanese context in a highly transparent manner. These guidelines can easily be used not only by specialists, but also by non-specialists, general clinicians, nurses, pharmacists, clinical engineers, and other healthcare professionals.
