Japanese guidelines for the management of Pain, Agitation, and Delirium in intensive care unit (J-PAD)

Japanese Clinical Practice Guidelines for Rehabilitation in Critically Ill Patients 2023 (J-ReCIP 2023)

Providing standardized, high-quality rehabilitation for critically ill patients is a crucial issue. In 2017, the Japanese Society of Intensive Care Medicine (JSICM) promulgated the "Evidence-Based Expert Consensus for Early Rehabilitation in the Intensive Care Unit" to advocate for the early initiation of rehabilitations in Japanese intensive care settings. Building upon this seminal work, JSICM has recently conducted a rigorous systematic review utilizing the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) methodology. This endeavor resulted in the formulation of Clinical Practice Guidelines (CPGs), designed to elucidate best practices in early ICU rehabilitation. The primary objective of this guideline is to augment clinical understanding and thereby facilitate evidence-based decision-making, ultimately contributing to the enhancement of patient outcomes in critical care settings. No previous CPGs in the world has focused specifically on rehabilitation of critically ill patients, using the GRADE approach. Multidisciplinary collaboration is extremely important in rehabilitation. Thus, the CPGs were developed by 73 members of a Guideline Development Group consisting of a working group, a systematic review group, and an academic guideline promotion group, with the Committee for the Clinical Practice Guidelines of Early Mobilization and Rehabilitation in Intensive Care of the JSICM at its core. Many members contributed to the development of the guideline, including physicians and healthcare professionals with multiple and diverse specialties, as well as a person who had been patients in ICU. Based on discussions among the group members, eight important clinical areas of focus for this CPG were identified. Fourteen important clinical questions (CQs) were then developed for each area. The public was invited to comment twice, and the answers to the CQs were presented in the form of 10 GRADE recommendations and commentary on the four background questions. In addition, information for each CQ has been created as a visual clinical flow to ensure that the positioning of each CQ can be easily understood. We hope that the CPGs will be a useful tool in the rehabilitation of critically ill patients for multiple professions.

Effect of a Japanese Version of the Burns Wean Assessment Program e-Learning Materials on Ventilator Withdrawal for Intensive Care Unit Nurses

BACKGROUND

No assessment tool for predicting ventilator withdrawal success is currently available in Japan. Thus, an accessible and valid assessment tool to address this issue is needed. The Burns Wean Assessment Program (BWAP) has been validated as a reliable predictor of ventilator withdrawal outcomes. However, nurses must be familiar with this tool to ensure its efficient utilization in clinical settings.

PURPOSE

This study was designed to examine the effect of a 26-item Japanese version of BWAP (J-BWAP) e-learning materials on ventilator withdrawal in a sample of intensive care unit nurses in Japan.

METHODS

The BWAP was translated into Japanese, checked, and verified as the J-BWAP. Nonrandomized intensive care unit nurses from six hospitals were assigned to three groups, including Intervention Group 1 (e-learning in one session), Intervention Group 2 (e-learning over three sessions during 1 week), and the control group. The participants underwent pretests and posttests using web-based, simulated patients. The primary outcome measure was the difference in online pretest and posttest total scores among the two intervention groups and the control group. The feasibility of the J-BWAP and its e-learning materials was evaluated using four frameworks: acceptability, demand, implementation, and adaptation.

RESULTS

Of the 48 participants in the study, 32 completed the posttest and were included in the analysis (dropout rate: 33.3%). The difference between pretest and posttest scores was significantly higher in the intervention groups than the control group (2 vs. -1, p = .0191) and in Intervention Group 2 than the control group (2.0 vs. -0.5, p = .049). The feasibility frameworks for the J-BWAP and its e-learning materials were mostly positive.

CONCLUSIONS/IMPLICATIONS FOR PRACTICE

The development of the J-BWAP and training nurses using e-learning were shown to be feasible in this study. The J-BWAP contents are appropriate for predicting the outcome of mechanical ventilation withdrawal. The J-BWAP has the potential to become a common tool among Japanese medical professionals after the contents are further simplified for daily application in clinical practice. Subsequent studies should verify the reliability and validity of this tool and test the real-world utility of the J-BWAP using randomized controlled trials in Japanese clinical settings.

Evaluation of severe adverse events during rehabilitation for acute-phase patients: A retrospective cohort study

Early mobilization decreases the likelihood of negative outcomes for acute-phase inpatients. Adverse events occurring during intensive care unit rehabilitation have previously been reported; however, no study has reported the incidence rates for adverse events during the acute rehabilitation phase. This study aimed to investigate the incidence of severe adverse events during acute-phase rehabilitation and evaluate them in detail.Reports of adverse events occurring during acute-phase rehabilitation in a university hospital from April 1, 2011 to March 31, 2018 were retrospectively assessed.Nine severe adverse events occurred during this period (incidence rate, 0.032%), comprising 2 cardiopulmonary arrests, 2 pulseless electrical activity events, 2 deterioration in consciousness events, 1 deterioration in consciousness event due to cerebral infarction, 1 fracture due to a fall, and 1 event involving removal of a ventricular drain. Pulmonary thromboembolism was implicated in 1 adverse event involving pulseless electrical activity and 1 deterioration in consciousness event. The causes for the 6 other adverse events could not be identified. The mean days from admission and the onset of rehabilitation to adverse event occurrence were 22.0 ± 18.2 and 17.9 ± 13.5 days (mean ± standard deviation), respectively. Four of 9 patients died, and 5 patients were discharged home or transferred to other stepdown facilities. When assessed retrospectively, there were no conflicts between patient conditions and the cancellation criteria of rehabilitation by the Japanese Association of Rehabilitation Medicine.The occurrences of severe adverse event may not be related to early mobilization (or onset time of rehabilitation) and compliance status of cancellation criteria.

The efficacy and safety of nurse-initiated sedation management in an intensive care unit: A two-phase prospective study in Japan

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.

The Japanese Clinical Practice Guidelines for Management of Sepsis and Septic Shock 2020 (J-SSCG 2020)

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.

Delirium and long term cognition in critically ill patients

Delirium, a form of acute brain dysfunction, is very common in the critically ill adult patient population. Although its pathophysiology is poorly understood, multiple factors associated with delirium have been identified, many of which are coincident with critical illness. To date, no drug or non-drug treatments have been shown to improve outcomes in patients with delirium. Clinical trials have provided a limited understanding of the contributions of multiple triggers and processes of intensive care unit (ICU) acquired delirium, making identification of therapies difficult. Delirium is independently associated with poor long term outcomes, including persistent cognitive impairment. A longer duration of delirium is associated with worse long term cognition after adjustment for age, education, pre-existing cognitive function, severity of illness, and exposure to sedatives. Interestingly, differences in prevalence are seen between ICU survivor populations, with survivors of acute respiratory distress syndrome experiencing higher rates of cognitive impairment at early follow-up compared with mixed ICU survivor populations. Although cognitive performance improves over time for some ICU survivors, impairment is persistent in others. Studies have so far been unable to identify patients at higher risk of long term cognitive impairment; this is an active area of scientific investigation.

A Pilot Study on Pain Assessment Using the Japanese Version of the Critical-Care Pain Observation Tool

BACKGROUND

Critically ill patients experience various types of pain that are difficult to assess because patients cannot communicate verbally due to artificial airways and sustained sedation. The Critical-Care Pain Observation Tool (CPOT) objectively evaluates patients' pain.

AIMS

This study aimed to re-assess the reliability and validity of the Japanese version (CPOT-J) and to reveal limitations of behaviors specific to mechanically ventilated patients.

DESIGN

Secondary analysis of observational pilot study and case report.

PARTICIPANTS

  METHODS: We obtained consent preoperatively from 40 cardiovascular surgery patients. CPOT-J scores were evaluated immediately before, immediately after, and 20 minutes after painful stimulation. Inter-rater reliability was determined by the researcher and 18 ICU nurses (minimum one-year ICU experience). Validity was examined by comparing CPOT-J with vital sign values and patients' self-reports of pain. Two cases revealed the tool's characteristics: one score was consistent with patient reports while the other was not.

RESULTS

We evaluated pain in 34 patients (26 men, 8 women; mean age = 66.8 years). Weighted kappa scores ranged from 0.48 to 0.94. The tool only correlated with changes in systolic blood pressure and pulse pressure. Case studies indicated that the tool effectively evaluated mid-sternum-wound pain, but not back pain at rest.

CONCLUSIONS

The CPOT-J can assess pain in mechanically ventilated patients, but being immobile results in a score of 0 for body movement (e.g., being immobile while feeling back pain) and is a limitation of the scoring.

Distorted Memories and Related Factors in ICU Patients

This study aimed to examine the relationship between memory status of and factors related to patients in the intensive care unit (ICU) using a cross-sectional study design. Participants were adult patients who were admitted to the general ICUs for more than 48 hours. One week after ICU discharge, a survey on memory distortion was conducted. Overall, 133 patients were included, of whom 51.1% reported distorted memories. Among them, 15.0% had memory loss; 48.1% had unrealistic experiences; 27.8% recalled confusion, panic, anxiety, and discomfort during their ICU stay; and 9% had traumatic experiences. Multiple logistic regression analyses revealed that memory loss was associated with an operation, and a significant association was observed between traumatic memory and pain. Opioid use may have a protective effect against memory loss. These results suggest the importance of relieving pain and preserving true memories during ICU treatment.

Comparison of clinical practice guidelines for the management of pain, agitation, and delirium in critically ill adult patients

Guideline‐based management approaches for pain, agitation, and delirium (PAD) in critically ill adult patients are widely believed to result in good outcomes. However, there are some differences in the recommendations and evidence levels among the management guidelines established for PAD. To identify and compare the current management guidelines, we used the PubMed database. The PAD guidelines and Federación Panamericana e Ibérica de Sociedades de Medicina Crítica y Terapia Intensiva (FEPIMCTI) guidelines were identified from our search. We compared the main aspects of these two guidelines as well as the Japanese guidelines for the management of PAD (J‐PAD guidelines). The PAD, FEPIMCTI, and J‐PAD guidelines contained a total of 4, 12, and 5 sections, having 32, 138, and 37 recommendations, respectively, pertaining to routine monitoring of pain in adult patients in the intensive care unit. Intravenous opioids were recommended as the first‐line drug of choice for treating pain. Sedative titrated to maintain a light, rather than deep, level of sedation can be given unless clinically contraindicated. Although neither the PAD nor J‐PAD guidelines recommend use of a pharmacologic delirium prevention protocol or treatment with any pharmacological agent to reduce the duration of delirium, the FEPIMCTI guidelines provide such recommendations. The FEPIMCTI guidelines provide suggestions on which analgesics to use for several different cases and present algorithms for sedation and analgesia. The outlines of the three guidelines are similar, and all reinforce the management of PAD to improve patient outcomes.

The Japanese Clinical Practice Guidelines for Management of Sepsis and Septic Shock 2016 (J-SSCG 2016)

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.

Factors affecting pain assessment scores in patients on mechanical ventilation

OBJECTIVE

To determine how respiratory status and other aspects of the patients' condition affect pain assessments.

METHODS

　Pain was assessed in 20 patients aged ≥20 years who underwent cardiovascular surgery, and required postoperative mechanical ventilation in an intensive care unit using the Behavioral Pain Scale (BPS). A BPS score of ≥6 (pain) versus <6 (no pain) was the dependent variable for determining the effect on pain.

RESULTS

　Multiple logistic regression analysis showed that in 99 observations made at rest, pre- and post-turning and pre- and post-tracheal suctioning, the BPS score was significantly affected by gender, the Acute Physiology and Chronic Health Evaluation (APACHE) II score, Richmond Agitation-Sedation Scale score, PaCO₂, and HCO₃^-. The associations between BPS scores and APACHE II scores and HCO₃^- demonstrated that pain results from biological responses to invasion. Increases in PaCO₂ affecting only the total BPS score suggests that PaCO₂ is associated with other pain responses, regardless of respiratory status.

CONCLUSION

　The BPS score was significantly associated with disease severity and ventilatory capacity, demonstrating a need to examine pain assessment methods tailored to the severity of underlying disease, degree of respiratory failure and other aspects of individual patient's condition for effective pain management.
