Influence of Physical Restraint on Unplanned Extubation of Adult Intensive Care Patients: A Case-Control Study

Prevalence and risk factors of the use of physical restraint and impact of a decision support tool: A before-and-after study

BACKGROUND

Physical restraint is frequently used in intensive care units to prevent patients' life-threatening removal of indwelling devices. In France, their use is poorly studied. Therefore, to evaluate the need for physical restraint, we have designed and implemented a decision support tool.

AIMS

Besides describing the prevalence of physical restraint use, this study aimed to assess whether the implementation of a nursing decision support tool had an impact on restraint use and to identify the factors associated with this use.

STUDY DESIGN

A large observational, multicentre study with a repeated one-day point prevalence design was conducted. All adult patients hospitalized in intensive care units were eligible for this study. Two study periods were planned: before (control period) and after (intervention period) the deployment of the decision support tool and staff training. A multilevel model was performed to consider the centre effect.

RESULTS

During the control period, 786 patients were included, and 510 were in the intervention period. The prevalence of physical restraint was 28% (95% CI: 25.1%-31.4%) and 25% (95% CI: 21.5%-29.1%) respectively (χ2 = 1.35; p = .24). Restraint was applied by the nurse and/or nurse assistant in 96% of cases in both periods, mainly to wrists (89% vs. 83%, p = .14). The patient-to-nurse ratio was significantly lower in the intervention period (1:3.0 ± 1 vs. 1:2.7 ± 0.7, p < .001). In multivariable analysis, mechanical ventilation was associated with physical restraint (aOR [95% CI] = 6.0 [3.5-10.2]).

CONCLUSION

The prevalence of physical restraint use in France was lower than expected. In our study, the decision support tool did not substantially impact physical restraint use. Hence, the decision support tool would deserve to be assessed in a randomized controlled trial.

RELEVANCE TO CLINICAL PRACTICE

The decision to physically restrain a patient could be protocolised and managed by critical care nurses. A regular evaluation of the level of sedation could allow the most deeply sedated patients to be exempted from physical restraint.

Position Statement of ISCCM Committee on Weaning from Mechanical Ventilator

Background and purpose

Weaning from a mechanical ventilator is a milestone in the recovery of seriously ill patients in Intensive care. Failure to wean and re-intubation adversely affects the outcome. The method of mechanical ventilation (MV) varies between different ICUs and so does the practice of weaning. Therefore, updated guidelines based on contemporary literature are designed to guide intensivists in modern ICUs. This is the first ISCCM Consensus Statement on weaning complied by a committee on weaning. The recommendations are intended to be used by all the members of the ICU (Intensivists, Registrars, Nurses, and Respiratory Therapists).

Methods

A Committee on weaning from MV, formed by the Indian Society of Critical Care Medicine (ISCCM) has formulated this statement on weaning from mechanical ventilators in intensive care units (ICUs) after a review of the literature. Literature was first circulated among expert committee members and allotted sections to each member. Sections of the statement written by sectional authors were peer-reviewed on multiple occasions through virtual meetings. After the final manuscript is accepted by all the committee members, it is submitted for peer review by central guideline committee of ISCCM. Once approved it has passed through review by the Editorial Board of IJCCM before it is published here as "ISCCM consensus statement on weaning from mechanical ventilator". As per the standard accepted for all its guidelines of ISCCM, we followed the modified grading of recommendations assessment, development and evaluation (GRADE) system to classify the quality of evidence and strength of recommendation. Cost-benefit, risk-benefit analysis, and feasibility of implementation in Indian ICUs are considered by the committee along with the strength of evidence. Type of ventilators and their modes, ICU staffing pattern, availability of critical care nurses, Respiratory therapists, and day vs night time staffing are aspects considered while recommending for or against any aspect of weaning.

Result

This document makes recommendation on various aspects of weaning, namely, definition, timing, weaning criteria, method of weaning, diagnosis of failure to wean, defining difficult to wean, Use of NIV, HFOV as adjunct to weaning, role of tracheostomy in weaning, weaning in of long term ventilated patients, role of physiotherapy, mobilization in weaning, Role of nutrition in weaning, role of diaphragmatic ultrasound in weaning prediction etc. Out of 42 questions addressed; the committee provided 39 recommendations and refrained from 3 questions. Of these 39; 32 are based on evidence and 7 are based on expert opinion of the committee members. It provides 27 strong recommendations and 12 weak recommendations (suggestions).

Conclusion

This guideline gives extensive review on weaning from mechanical ventilator and provides various recommendations on weaning from mechanical ventilator. Though all efforts are made to make is as updated as possible one needs to review any guideline periodically to keep it in line with upcoming concepts and standards.

Adverse events related to physical restraint use in intensive care units: A review of the literature

Physical restraints are widely used and accepted as protective measures during treatment in intensive care unit (ICU). This review of the literature summarizes the adverse events and outcomes associated with physical restraint use, and the risk factors associated with their use during treatment in the ICU. The PubMed, Scopus, and Google Scholar databases were screened using predefined search terms to identify studies pertaining to adverse events and/or outcomes associated with physical restraint use, and the factors associated with their use in adult patients admitted to the ICU. A total of 24 articles (including 6126 patients) that were published between 2006 and 2022 were identified. The described adverse events associated with physical restraint use included skin injuries, subsequent delirium, neurofunctional impairment, and a higher rate of post-traumatic stress disorder. Subsequent delirium was the most frequent adverse event to be reported. No alternative measures to physical restraints were discussed, and only one study reported a standardized protocol for their use. Although physical restraint use has been reported to be associated with adverse events (including neurofunctional impairment) in the literature, the available evidence is limited. Although causality cannot be confirmed, a definite association appears to exist. Our findings suggest that it is essential to improve awareness regarding their adverse impact and optimize approaches for their detection, management, and prevention using protocols or checklists.

Analytical Review of Unplanned Extubation in Intensive Care Units and Recommendation on Multidisciplinary Preventive Approaches

Unplanned extubations (UE) frequently occur in critical care units. These events are precipitated by many risk factors and are associated with adverse outcomes for patients. We reviewed the current literature to examine factors related to UE and presented the analysis of 41 articles critical to the topic. Our review has identified specific risk factors that we discuss in this review, such as sedation strategies, physical restraints, endotracheal tube position, and specific nursing care aspects associated with an increased incidence of UE. We recommend interventions to reduce the risk of UE. However, we recommend that bundled rather than a single intervention is likely to yield higher success, given the heterogeneity of factors contributing to increasing the risk of UE.

Phase I pilot safety and feasibility of a novel restraint device for critically ill patients requiring mechanical ventilation

Background

Mechanically ventilated Intensive Care Unit (ICU) patients often require wrist restraints, contributing to immobility and agitation, over-sedation, and delirium. The Exersides® Refraint® (Healthy Design, LLC), a novel restraint alternative, may be safe and facilitate greater mobility than traditional restraints.

Objective

This National Institutes of Health Small Business Technology Transfer (STTR) Program Grant-funded single-site Phase I feasibility study evaluated Exersides® safety and feasibility in anticipation of a multi-site Phase II randomized controlled trial (RCT).

Methods

In two academic ICUs, mechanically ventilated adults ⩾25 years old who were non-comatose, required restraints and had an expected stay of ⩾2 days were enrolled to wear Exersides® and traditional wrist restraints for 4 h on day 1, in a randomized order, and in the reverse order on day 2. Main outcomes were Exersides® safety (i.e., patient/clinician lacerations/injuries), feasibility (i.e., ⩾90% of required data collected), and patient/family/clinician feedback.

Results

Eight patients were enrolled; one no longer required restraints at initiation, yielding seven subjects (median [interquartile range (IQR)] age 65 [55, 70] years, 86% men). All seven wore Exersides®, averaging (SD) 2.5 (1.0) hours per session, with no safety events reported. Across restraint time periods, 92% and 100% of Richmond Agitation-Sedation Scale (RASS) and wrist actigraphy data, respectively, were collected. Feedback was positive (more movement and comfortable than traditional restraints) and constructive (bulky, intimidating to apply).

Conclusions

This pilot study provided key safety and feasibility data for a Phase II RCT evaluating Exersides® versus traditional wrist restraints. Feedback motivated minor device modifications before RCT initiation.

Interprofessional intensive care unit (ICU) team perspectives on physical restraint practices and minimization strategies in an adult ICU: A qualitative study of contextual influences

BACKGROUND

Guidelines advocate for minimization of physical restraint (PR) use in intensive care units (ICU). Interprofessional team perspectives on PR practices can inform the design and implementation of successful PR minimization interventions.

AIM

To identify ICU staff perspectives of contextual influences on PR practices and minimization strategies.

STUDY DESIGN

A qualitative descriptive study in a single ICU in Toronto, Canada. One-on-one semi-structured interviews were conducted with 14 ICU staff. A deductive content analysis of interviews was undertaken using the integrated-Promoting Action on Research Implementation in Health Services (i-PARIHS) framework.

RESULTS

Five themes were developed: risk-averse culture, leadership, practice monitoring and feedback processes, environmental factors, and facilitation. Participants described a risk-averse culture where prophylactic application of PR for intubated patients was used to prevent unplanned extubation thereby avoiding blame from colleagues. Perceived absence of leadership and interprofessional team involvement situated nurses as the primary decision-maker for restraint application and removal. Insufficient monitoring of restraint practices, lack of access to restraint alternatives, and inability to control environmental contributors to delirium and agitation further increased PR use. Recommendations as to how to minimize restraint use included a nurse facilitator to advance leadership-team collaboration, availability of restraints alternatives, and guidance on situations for applying and removing restraints.

CONCLUSIONS

This analysis of contextual influences on PR practices and minimization using the i-PARIHS framework revealed potentially modifiable barriers to successful PR minimization, including a lack of leadership involvement, gaps in practice monitoring, and collaborative decision-making processes. A team approach to changing behaviour and culture should be considered for successful implementation and sustainability of PR minimization.

RELEVANCE TO PRACTICE

The establishment of an interprofessional facilitation team that addresses risk-averse culture and promotes collaboration among ICU stakeholders will be crucial to the success of any approach to restraint minimization.

[Restraint in intensive care: between patient safety and respect for autonomy]

The use of physical restraint in the context of medical resuscitation is relatively frequent. Although temporary or prolonged physical restraint is justified by patient safety (possibility of self-extubation, etc.), this practice is itself a source of risk, leads to suffering on the part of the patient, and raises dilemmas and ethical questions within teams. Inherent to the working conditions and training of professionals, restraint must nevertheless be balanced and lead to the search for alternatives.

Coding for Physical Restraint Status Among Hospitalized Patients: a 2019 National Inpatient Sample Analysis

BACKGROUND

The reduction of physical restraint utilization in the hospital setting is a key goal of high-quality care, but little is known about the rate of restraint use in general hospitals in the USA.

OBJECTIVE

This study reports the rate of physical restraint coding among acute care hospital discharges in the USA and explores associated demographic and diagnostic factors.

DESIGN

The National Inpatient Sample, a de-identified all-payors database of acute care hospital discharges in the USA, was queried for patients aged 18 and older with a diagnosis code for physical restraint status in 2019.

PARTICIPANTS

Hospitalized patients aged 18 and older.

MAIN MEASURES

Demographics, discharge diagnoses, in-hospital mortality, length of stay, total hospital charges.

KEY RESULTS

In total, 220,470 (95% CI: 208,114 to 232,826) hospitalizations, or 0.7% of overall hospitalizations, included a discharge code for physical restraint status. There was a 700-fold difference in coding for restraint utilization based on diagnosis, with 7.4% of patients with encephalitis receiving restraint diagnosis codes compared to < 0.01% of patients with uncomplicated diabetes. In an adjusted model, male sex was associated with an odds ratio of 1.4 (95% CI: 1.4 to 1.5) for restraint utilization coding, and Black race was associated with an odds ratio of 1.3 (95% CI: 1.2 to 1.4) relative to white race.

CONCLUSIONS

In the general hospital setting, there is variability in physical restraint coding by sex, race, and clinical diagnosis. More research is needed into the appropriate utilization of restraints in the hospital setting and possible inequities in restraint utilization.

Physical restraint practices in an adult intensive care unit: A prospective observational study

AIM AND OBJECTIVES

To conduct a diagnostic evaluation of physical restraint practice using the integrated-Promoting Action on Research Implementation in Health Services (i-PARIHS) framework.

BACKGROUND

Evidence indicates that physical restraints are associated with adverse physical, emotional and psychological sequelae and do not consistently prevent intensive care unit (ICU) patient-initiated device removal. Nevertheless, physical restraints continue to be used extensively in ICUs both in Canada and internationally. Implementation science frameworks have not been previously used to diagnose, develop and guide the implementation of restraint minimisation interventions.

DESIGN

A prospective observational study of restrained patients in a 20-bed, academic ICU in Toronto, Canada.

METHODS

Data collection methods included patient observation, electronic medical record review, and verbal check with the point-of-care nurses. Data were collected pertaining to framework domains of unit culture (restraint application/removal), evaluation capacity (documentation) and leadership (rounds discussion). The reporting of this study followed the STROBE guidelines.

RESULTS

A total of 102 restrained patients, 67 (66%) male and mean age 58 years (SD 1.92), were observed. All observed devices were wrist restraints. Restraint application and removal time was verified in 83 and 57 of 102 patients respectively. At application, 96.4% were mechanically ventilated and 71% sedated/unarousable. Nurses confirmed 71% were prophylactically restrained; 7.2% received restraint alternatives. Restraint removal occurred after interprofessional team rounds (87%), during daytime (79%) and following extubation (52.6%). Of the 923 discrete patient observation of physical restraint use, 691 (75%) were not documented. Of the 30 daytime interprofessional team rounds reviewed, physical restraint was discussed at 3 (10%).

CONCLUSION

In this single-centre study, a culture of prophylactic physical restraint was observed. Future facilitation of restraint minimisation warrants theoretically informed implementation strategies including leadership involvement to advance interprofessional collaboration.

RELEVANCE TO CLINICAL PRACTICE

The findings draw attention to the importance of a preliminary diagnostic study of the context prior to designing, and implementing, a physical restraint minimisation intervention.

Quality improvement project to reduce unplanned extubations in a paediatric intensive care unit

BACKGROUND

Unplanned extubations are recurrent adverse events in mechanically ventilated children and have been the focus of quality and safety improvement in paediatric intensive care units (ICUs).

LOCAL PROBLEM

To reduce the rate of unplanned extubation in the paediatric ICU by 66% (from 2.02 to 0.7).

METHODS

This is a quality improvement project that was conducted in a paediatric ICU of a private hospital at the quaternary level. All hospitalised patients who used invasive mechanical ventilation between October 2018 and August 2019 were included.

INTERVENTIONS

The project was based on the Improvement Model methodology of the Institute for Healthcare Improvement to implement change strategies. The main ideas of change were innovation in the endotracheal tube fixation model, evaluation of the endotracheal tube positioning, good practices of physical restraint, sedation monitoring, family education and engagement and checklist for prevention of unplanned extubation, with Plan-Do-Study-Act, the tool chosen to test and implement ideas for change.

RESULTS

The actions reduced the unplanned extubation rate to zero in our institution and sustained this result for a period of 2 years, totalling 743 days without any event. An estimate was made comparing cases with unplanned extubation and controls without the occurrence of this adverse event, which resulted in savings of R$955 096.65 (US$179 540.41) during the 2 years after the implementation of the improvement actions.

CONCLUSION

The improvement project conducted in the 11-month period reduced the unplanned extubation rate to zero in our institution and sustained this result for a period of 743 days. Adherence to the new fixation model and the creation of a new restrictor model, which enabled the implementation of good practices of physical restraint were the ideas of change that had the greatest impact in achieving this result.

Coercion in intensive care, an insufficiently explored issue-a scoping review of qualitative narratives of patient's experiences

Purpose

The use of coercion, in a clinical context as imposing a measure against a patient's opposition or declared will, can occur in various forms in intensive care units (ICU). One prime example of a formal coercive measure in the ICU is the use of restraints, which are applied for patients' own safety. Through a database search, we sought to evaluate patient experiences related to coercive measures.

Results

For this scoping review, clinical databases were searched for qualitative studies. A total of nine were identified that fulfilled the inclusion and the CASP criteria. Common themes emerging from the studies on patient experiences included communication issues, delirium, and emotional reactions. Statements from patients revealed feelings of compromised autonomy and dignity that came with a loss of control. Physical restraints were only one concrete manifestation of formal coercion as perceived by patients in the ICU setting.

Conclusion

There are few qualitative studies focusing on patient experiences of formal coercive measures in the ICU. In addition to the experience of restricted physical movement, the perception of loss of control, loss of dignity, and loss of autonomy suggests that restraining measures are just one element in a setting that may be perceived as informal coercion.

A Nomogram for Predicting Physical Restraint of Patients in Intensive Care Unit

Background

Despite its ethical implications, physical restraint (PR) is widely used in the intensive care unit (ICU) to guarantee the safety of patients. This study investigated the frequency and risk factors of PR use for patients in the ICU to establish a predictive nomogram.

Methods

Clinical parameters of patients admitted to the ICU of Jiangsu Province Hospital from January 2021 to July 2021 were retrospectively collected. Independent risk factors of PR were analyzed by univariate and multivariate logistic regression analyses. The R software was used to establish the nomogram. Model performance was validated using the concordance-index (C-index) and calibration curves.

Results

The rate of PR use was 46.32% (233/503 patients). Age (B = 0.036, odds ratio [OR]: 1.037, 95% confidence interval [CI]: 1.022-1.052, P < 0.001), consciousness disorder (B = 0.770, OR: 2.159, 95% CI: 1.216-3.832, P=0.009), coma (B = -1.666, OR: 0.189, 95% CI: 0.101-0.353, P < 0.001), passive activity (B = 1.014, OR: 2.756, 95% CI: 1.644-4.618, P < 0.001), delirium (B = 0.993, OR: 2.699, 95% CI: 1.097-6.642, P=0.031), -3 < Richmond Agitation Sedation Scale (RASS) score <2 (B = 0.698, OR: 2.009, 95% CI: 1.026-3.935, P=0.042), RASS score ≥2 (B = 1.253, OR: 3.499, 95% CI: 1.126-10.875, P=0.030), and mechanical ventilation (B = 1.696, OR: 5.455, 95% CI: 2.804-10.611, P < 0.001) were identified as independent risk factors for PR in the ICU (P < 0.05) and included in the nomogram. The C-index was 0.830, and the calibration curve indicated good discriminatory ability and accuracy (mean absolute error: 0.026).

Conclusion

The prediction nomogram model of PR in ICU was established based on age, mobility, delirium, consciousness, RASS score, and mechanical ventilation. It showed good discrimination and accuracy. This nomogram may predict the probability of PR use in the ICU and guide nurses in developing precise interventions to reduce the rate of PR.

Risk factors of self-extubation in intensive care. Retrospective cohort study

Introduction: Acute respiratory failure remains one of the three leading causes of admission to the intensive care unit (ICU). Self-extubation is an adverse outcome requiring reintubation in 50% of cases. Objective: To assess for determinants (risk factors) of self-extubation and mortality in the ICU by using a generalized estimation equation model (GEE). Methods: The data was collected from a retrospective cohort study from 2017-2020 including all patients admitted to the ICU with mechanical ventilation. Univariate and bivariate analyses were performed. Then, a GEE model was conducted to predict the risk of self-extubation and mortality. Results: A total of 857 subjects were included, with a mean age of 60.5 +/- 17 years-old. Most of the subjects were males (55.2%). An 8.99-fold risk (95%CI 3.83-21.1, p<0.01) of self-extubation was identified in patients with agitation. Exposure to infusion of neuromuscular blockade was also found to increase the risk of self-extubation 3.37 times (95%CI 1.31-8.68, p=0.01). No associations were identified between immobilization and self-extubation (OR 1.38 95%CI 0.76-2.51, p=0.29). Finally, light sedation according to the Richmond Sedation Scale (RASS) between 0 to -2 rather than moderate (RASS-3) reduces the risk of mortality (OR 0.57, 95%CI 0.38-0.83, p<0.01). Conclusions: The main factors resulting in self-extubation were: agitation, delirium, and infusion of neuromuscular blocking agents. An association was found between light sedation and a lower risk of mortality. No association was found between the use of physical restraint and the desired outcome.

Magnitude and associated factors of unplanned extubation in intensive care unit: A multi-center prospective observational study

Background

Unplanned extubation is the removal of an endotracheal tube accidently during procedural activities or by the action of the patient. It is one of the commonly reported complications among mechanically ventilated patients in the intensive care unit. This study aimed to assess the magnitude and associated factors of unplanned extubation in intensive care units at referral hospitals in Addis Ababa, Ethiopia, 2021.

Methods

Institutional based prospective observational study was conducted on 317 intubated patients in the intensive care unit at referral hospitals of Addis Ababa, Ethiopia, from January 8, 2021–May 9, 2021. Data were collected using a structured questionnaire. Descriptive statics were expressed in percentages and presented with tables and figures. Both Bivariable and multivariable logistic analysis was done to identify factors associated with unplanned extubation in intensive care unit. P < 0.05 with 95% CI was set as Statistical significance.

Result

The prevalence of unplanned extubation in this study was 19.74%. Being male (AOR = 3.132, 95%CI: 1.276–7.69), duration of intubation <5days (AOR = 2.475, 95% CI: 1.039–5.894), managed by junior resident (AOR = 5.25, 95% CI: 2.125–12.969), being physically restrained (AOR = 4.356, 95%CI: 1.786–10.624), night shift (AOR = 3.282, 95%CI:1.451–7.424)and agitation (AOR = 4.934,95%CI:1.934–12.586) were significantly contribute to the occurrence of unplanned extubation.

Conclusion

and recommendation: This study showed that the prevalence of unplanned extubation was high in the intensive care unit. We suggest to intensive care unit staff to give special attention to early intubated patients, especially male individuals and the stakeholders of hospitals should rearrange the time of shift and physician schedules in the intensive care unit.

•

Magnitude of unplanned extubation was high in the intensive care unit.

•

Duration of intubation less than 5 days was significantly associated.

•

Give special attention to early intubated patients and rearrange the time of shift.

COVID-EX. Influence de la pandémie de Covid-19 sur le taux d’extubation non programmée en réanimation : étude castemoins rétrospective

CONTEXT

In ICUs, many patients are intubated. UE is an indicator of the quality of care.Isolation associated with "air" precautions may increase the number of UEs in mechanically ventilated (MV) COVID patients.The main aim of the study was to compare the rate of UE between a COVID-19 period and a control period. The secondary aims were to identify UE risk factors and to study the experience of caregivers during the COVID-19 period.

METHOD

The method of choice was a retrospective single center case-control study. MV patients aged ≥ 18 years were eligible in two periods: the control period from 01/02/2020 to 29/02/2020, and the COVID-19 period from 01/03/2020 to 31/03/2020. An anonymous survey was given to ICU caregivers in Vannes Hospital.

RESULTS

The UE rate was 17% (n=7) vs. 20% (n=9) control period vs. COVID-19 period (p=0.58), with nocturnal preponderance (75%). A quarter (n=4) of patients fulfill MV weaning criteria at the time of UE. A 71% (n=49) survey response rate was obtained. The COVID-19 period had a higher estimated UE risk for 76% (n=37) of caregivers, who felt that they had a greater workload, difficulties with monitoring, and decreased regular visits to patients' rooms.

CONCLUSION

Contrary to the caregiver experience, we reported a similar UE rate over both the COVID-19 period and the control period.

Physical Restraint and Associated Factors in Adult Patients in Intensive Care Units: A Cross-sectional Study in North of Iran

Background/aim

Patients in the intensive care units (ICUs) are at high risk of developing delirium and agitation. Physical restraint (PR) has increased to control these patients which accompanies by adverse consequences. The aim was to determine the PR use and associated factors in patients hospitalized at the ICUs in the North of Iran.

Materials and methods

In this cross-sectional study, a total of 272 patients in 3 ICUs of 5 Azar referral hospital affiliated to Golestan University of Medical Sciences (Gorgan, Iran) in 2018 were included. Confusion assessment method for the ICU (CAM-ICU), Richmond Agitation-Sedation Scale (RASS), acute physiology and chronic health evaluation II (APACHE II), and Glasgow Coma Scale (GCS) were used to evaluate delirium, sedation level, disease severity, and level of consciousness, respectively. Analysis was done by STATA version 14.2 (StataCorp LP, College Station, Texas), univariate and multiple analyses.

Results

Data from 272 patients were analyzed (mean age of 45.8 ± 21.3 years). PR was used for 74.5% of patients. Restrained patients had more severe disease [mean of APACHE II score, 20.20 (7.5) vs 11.6 (7.1)], longer length of stay [mean of 10 (5.5) vs 5.5 (4.6) days], and lower level of consciousness [mean of GCS score, 8.7 (3.5) vs 13.5 (3.3)] than patients without it. CAM-ICU was positive in majority of patients (79.5 vs 10.4%) and agitation level of RASS score was higher in restrained patients (31.7 vs 3.0%). Associated factors in multiple analysis were use of sedative and psychoactive drugs [odds ratio (OR), 2.85; 95% confidence interval (CI): 1.04-7.82], presence of delirium (OR, 15.13; 95% CI: 4.61-49.65), deep sedation (OR, 0.04; 95% CI: 0.00-0.45), and GCS score (OR, 0.69; 95% CI: 0.53-0.9).

Conclusion

This study revealed the high use of PR in the ICUs, and use of sedative and psychoactive drugs, presence of delirium, deep sedation, and GCS score were such associated factors.

Quality appraisal of guidelines on physical restraints in intensive care units: A systematic review

BACKGROUND

Guidelines concerning the use of physical restraints in medical facilities have been published and amended over the years. However, the quality and suitability of these guidelines have not been appraised.

OBJECTIVES

This study aims to assess the suitability and quality of guidelines for the use of physical restraints in intensive care units with the AGREE-REX and AGREE Ⅱ instruments.

METHODS

A systematic search of electronic databases (e.g., EMBASE), cross-database search platforms (e.g., Clinical Key), guideline web portals (e.g., Guidelines International Network) and society websites (e.g., Society of Critical Care Medicine) was conducted from January 2011 to December 2020. The methodological quality was assessed using AGREE Ⅱ, and the recommendation quality and suitability were assessed using AGREE-REX instruments.

RESULTS

A total of eight guidelines were included. The criteria for overall quality and suitability of guidelines for the use of physical restraints were met by 50-72% and 59-76%, respectively. The "Values and Preferences" domain had the lowest score (38% ± 9%). The criteria for methodological quality of the guidelines were met by 50-83%. Two domains, "Applicability" and "Editorial Independence", achieved lower scores. There was a strong, positive correlation between the overall methodological quality of guidelines and the overall quality of recommendations (r = 0.968).

CONCLUSION

There is a potential feasibility of guideline adaptation for the management of physical restraints. In order to implement a physical restraint guideline, the following aspects should be considered: (i) minimize the use of physical restraints, (ii) analyze barriers and facilitators relative to the local context, (iii) consider any specifications, and (iv) modify recommendations to local situation or individual conditions of the patient.

Implementation of nonpharmacologic physical restraint minimization interventions in the adult intensive care unit: A scoping review

OBJECTIVE

To identify the elements informing the successful implementation of nonpharmacologic physical restraint minimization interventions in adult intensive care unit patients. To map those elements to innovation, context, recipients and facilitation domains of the integrated-Promoting Action on Research Implementation in Health Services (i-PARIHS) framework and to describe the outcomes of those interventions.

METHODOLOGY

A scoping review of studies published in English reporting on restraint minimization interventions in adult intensive care units. We searched seven databases (MEDLINE, CIHAHL, Embase, Web of Science, Cochrane Library, PROSPERO and Joanna Briggs) from inception to 2021. Two authors independently screened articles for inclusion, extracted study characteristics and mapped intervention data to the i-PARIHS domains.

RESULTS

Seven studies met inclusion criteria. Innovations comprised multicomponent interventions including education, decision aids/protocols and restraint alternatives. No studies utilised an implementation science framework to diagnose the baseline practice context. A commonly reported barrier to restraint minimization was a risk averse culture. Change was mostly driven by the external context (i.e. national regulations). Overall, nurses were the primary facilitators and recipients of practice change. Outcomes were changes in restraint incidence and prevalence abstracted from the medical record. However, no study validated the accuracy of restraint documentation. All studies documented an initial decrease in physical restraint use, but no long-term results were reported.

CONCLUSION

Restraint minimization intervention studies report nurse-facilitated multicomponent interventions and short-term practice change. Future restraint minimization research incorporating implementation science frameworks, interprofessional teams and patient/family perspectives is warranted.

Superficial placement of endotracheal tubes associated with unplanned extubation: A case-control study

INTRODUCTION

Unplanned extubations (UEs) refer to the inadvertent removal of endotracheal tubes (ETTs). Superficially placed ETTs anecdotally increases the risk of UEs. This study aims to assess the impact of ETT position as well as other factors that could be associated with risk of UEs.

METHOD

A retrospective case-control study was conducted at NewYork-Presbyterian Queens Hospital from January 2017 to February 2020. All adults admitted to intensive care units (ICUs) who received mechanical ventilation (MV) through ETTs were screened to identify UEs. For each case with UE, two controls with planned extubation were identified. A multivariate logistic regression was conducted to identify risk factors associated with UEs.

RESULTS

1100 patients received MV through ETTs during the time period. The incidence of UE was 4.9%. 53 patients with UEs and 106 patients with planned extubation were included for statistical analysis. Overall, patients with UE had higher in-hospital mortality rates (26.4% versus 11.3%, P = 0.02) and reintubation rates (28.3% versus 6.6%, P < 0.001). Within the UE group, patients who required reintubation had significantly higher in-hospital mortality rates than those who did not require reintubation (53.3% versus 15.8%, P = 0.005). Multivariate logistic regression showed higher APACHE II scores (Odds ratios (OR) 1.07; 95% Confidence interval (CI), 1 to 1.13), distance of ETT tips to carina ≥6 cm (OR 6.41; 95% CI, 1.1 to 37.3), physical restraint use (OR 2.98; 95% CI, 1.28 to 6.95) and continuous infusions of sedatives and/or analgesics (OR 10.72, 95% CI, 4.19 to 27.43) were associated with UE.

CONCLUSION

UE and the need for reintubation is associated with worse outcomes. Distance of ETT tips to carina ≥6 cm may be associated with higher risks of UE. Further prospective studies are needed to establish the optimal position of ETT to prevent UE.

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.

Physical Restraints and Post-Traumatic Stress Disorder in Survivors of Critical Illness. A Systematic Review and Meta-analysis

Rationale: Physical restraints are used liberally in some intensive care units (ICUs) to prevent patient harm from device removal or falls. Although the intention of restraint use is patient safety, their application may inadvertently cause physical or psychological harm. Physical restraints may contribute to post-traumatic stress disorder (PTSD), but there is a paucity of supportive data.Objectives: To investigate the association between physical restraint use and PTSD symptoms in ICU survivors. Secondary objectives were to examine the cognitive and physical outcomes associated with physical restraint use and to assess interventions that may be effective in reducing restraint use.Methods: A systematic review of English language studies in PubMed, Medline, Embase, CINAHL, and CENTRAL between January 1, 1990, to February 8, 2020 was performed. Observational or randomized studies that reported on restraint use and associated outcomes, or interventions to reduce restraint use, in critically ill adult patients were identified. Two independent reviewers completed the review in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines.Results: We identified 794 articles, of which 37 met inclusion criteria and were included. Thirty of these studies related to patient outcomes including PTSD, delirium, mechanical ventilation hours, and physical injury. Seven related to interventions to reduce physical restraint use. The quality of studies was not high; only four of the included studies were assessed to have a low risk of bias. Three studies found a significant relationship between restraint use and PTSD, but their results could not be pooled for analysis. Pooled data indicated a significant association between physical restraint use and delirium (odds ratio [OR], 11.54; 95% confidence interval [CI], 6.66-20.01; P < 0.001) and duration of mechanical ventilation (mean difference in days, 3.35; 95% CI, 1.95-4.75; P < 0.001). We also found that interventions, such as nursing education, may effectively reduce restraint use by approximately 50% (OR, 0.48; 95% CI, 0.32-0.73; P < 0.001). The impact that a reduction in restraint use may have on associated outcomes was not examined.Conclusions: Physical restraint use may be associated with PTSD in ICU survivors and is associated with delirium and longer duration of mechanical ventilation. Nurse education is likely effective in reducing rates of physical restraint among ICU patients.

Development and Validation of Unplanned Extubation Prediction Models Using Intensive Care Unit Data: Retrospective, Comparative, Machine Learning Study

Background

Patient safety in the intensive care unit (ICU) is one of the most critical issues, and unplanned extubation (UE) is considered the most adverse event for patient safety. Prevention and early detection of such an event is an essential but difficult component of quality care.

Objective

This study aimed to develop and validate prediction models for UE in ICU patients using machine learning.

Methods

This study was conducted in an academic tertiary hospital in Seoul, Republic of Korea. The hospital had approximately 2000 inpatient beds and 120 ICU beds. As of January 2019, the hospital had approximately 9000 outpatients on a daily basis. The number of annual ICU admissions was approximately 10,000. We conducted a retrospective study between January 1, 2010, and December 31, 2018. A total of 6914 extubation cases were included. We developed a UE prediction model using machine learning algorithms, which included random forest (RF), logistic regression (LR), artificial neural network (ANN), and support vector machine (SVM). For evaluating the model’s performance, we used the area under the receiver operating characteristic curve (AUROC). The sensitivity, specificity, positive predictive value, negative predictive value, and F1 score were also determined for each model. For performance evaluation, we also used a calibration curve, the Brier score, and the integrated calibration index (ICI) to compare different models. The potential clinical usefulness of the best model at the best threshold was assessed through a net benefit approach using a decision curve.

Results

Among the 6914 extubation cases, 248 underwent UE. In the UE group, there were more males than females, higher use of physical restraints, and fewer surgeries. The incidence of UE was higher during the night shift as compared to the planned extubation group. The rate of reintubation within 24 hours and hospital mortality were higher in the UE group. The UE prediction algorithm was developed, and the AUROC for RF was 0.787, for LR was 0.762, for ANN was 0.763, and for SVM was 0.740.

Conclusions

We successfully developed and validated machine learning–based prediction models to predict UE in ICU patients using electronic health record data. The best AUROC was 0.787 and the sensitivity was 0.949, which was obtained using the RF algorithm. The RF model was well-calibrated, and the Brier score and ICI were 0.129 and 0.048, respectively. The proposed prediction model uses widely available variables to limit the additional workload on the clinician. Further, this evaluation suggests that the model holds potential for clinical usefulness.

Decline in Physical Restraint Use Following Implementation of Institutional Guidelines

OBJECTIVE

To investigate the strategies implemented at our institution to reduce medical restraint use.

BACKGROUND

Restraints have been utilized to prevent agitation, self-extubations, and falls, although they are often associated with negative repercussions for nurses and patients.

METHODS

The restraint data at our institution were compared with the National Database of Nursing Quality Indicators (NDNQI) benchmark. We also described the measures taken to improve restraint documentation.

RESULTS

The number of patients in medical restraints, medical restraint hours, medical restraints/patient-days, and deaths in restraints at our institution all significantly decreased (P < 0.00001). There were 27 self-extubations of restrained patients compared with 11 self-extubations of nonrestrained patients. The percentage of inpatients with restraints in critical care and step-down areas declined and remained below the NDNQI benchmark.

CONCLUSIONS

This study reports the processes implemented to reduce restraint use through enhanced communication and increased documentation. Further exploration into factors that may attain a restraint-free environment is warranted.

Nurses' knowledge and attitudes regarding physical restraint in Turkish intensive care units

BACKGROUND

Physical restraint is still widely used despite studies supporting a reduction in its use. The development of guidelines to reduce the use of PR first requires the identification of factors related to the use of alternative methods.

AIM

This study aimed to determine factors associated with the use of alternatives to physical restraint (PR) in intensive care units.

DESIGN

This was a cross-sectional descriptive study.

METHODS

Data were collected from adult intensive care units of three hospitals in Turkey using the Physical Restraint Knowledge, Attitude and Practice Scale and a questionnaire including open-ended questions.

RESULTS

Overall, 202 nurses (80% response rate) completed the questionnaire. Nurses' knowledge, attitude, and practice scores regarding PR were 6.89 ± 1.79, 29.85 ± 4.93, and 36.76 ± 3.36, respectively. PR was reported to be necessary for patients at risk of self-harm, with dangerous behaviours, and who were trying to remove their catheters. Most nurses (64.9%) stated that they needed a written doctor's order. Analysis of free-text responses showed that patient disorientation (because of delirium, sedation, or agitation), nurses' workload, and lack of training regarding restraint were the primary reasons why nurses could not use alternatives. The main alternatives suggested by nurses were categorized as sedation, communication, and environmental regulation. Logistic regression analysis identified training (P = .009), working unit (P = .001), and nurses' practice score to use PR (P = .004) as independent risk factors for not using alternative methods of PR.

CONCLUSIONS

The results of this study revealed a moderate level of knowledge, attitude, and practice among nurses regarding the use of PR. Thus, education of nurses about the prevention of delirium and alternatives to PR according to the characteristics of their units is required.

RELEVANCE TO CLINICAL PRACTICE

Clinical guidelines and in-service training need to be developed to increase the use of alternatives to PR and delirium management.

The use of physical restraints in Chinese long-term care facilities and its risk factors: An observational and cross-sectional study

AIM

To investigate the use of physical restraints among Chinese long-term care facilities older adults and to identify its risk factors.

DESIGN

Observational and cross-sectional study.

METHODS

A total of 1,026 older adults from six long-term care facilities in Chongqing were recruited by cluster sampling method from July - November 2019. Data on physical restraint use and older adults' characteristics were collected using physical restraints observation forms and older adults' records. Organizational data were collected by questionnaires asking nursing managers. The independent risk factors for physical restraints use were assessed using chi-square test and binary logistic regression.

RESULTS

The study found that the prevalence of physical restraints in six long-term care facilities in China was 25.83%. Waist belt (55.47%) and wrist restraint (52.83%) were most frequently used. Only 61.51% of physical restraints were signed with informed consent. 71.70% of physical restraints were caused by the prevention of falls, 89.06% of physical restraints were without nursing documentation, and 13.58% restrained older adults were observed to have physical complications. According to the binary logistic regression analysis, facility type and ownership, older adults per nursing assistant, length of residence, cognitive impairment, care dependency, mobility restriction, fall risk, physical agitation, and indwelling tubes emerged as important risk factors for the use of physical restraints.

CONCLUSION

The use of physical restraints among Chinese long-term care facilities older adults was at a relatively high level and lack standardized and regulated practices. Moreover, Physical restraint use was associated with facility type and ownership, older adults per nursing assistant, length of residence, cognitive impairment, care dependency, mobility restriction, fall risks, physical agitation, and indwelling tube.

IMPACT

This study will provide an effective reference for nursing staff in long-term care facilities to assess high-risk older adults in their use of physical restraints, which can support them to implement effective minimized restraint approaches to targeted people.

Predictors of New-Onset Physical Restraint Use in Critically Ill Adults

BACKGROUND

Physical restraints are frequently used for intensive care patients and are associated with substantial morbidity. The effects of common evidence-based critical care interventions on use of physical restraints remain unclear.

OBJECTIVE

To identify independent predictors of new-onset use of physical restraints in critically ill adults.

METHODS

Secondary analysis of a prospective cohort study involving 5 adult intensive care units in a tertiary care medical center in the United States. Use of physical restraints was determined via daily in-person assessments and medical record review. Mixed-effects logistic regression analysis was used to examine factors associated with new-onset use of physical restraints, adjusting for covariates and within-subject correlation among intensive care unit days.

RESULTS

Of 145 patients who were free of physical restraints within 48 hours of intensive care unit admission, 24 (16.6%) had restraints newly applied during their stay. In adjusted models, delirium (odds ratio [OR], 5.09; 95% CI, 1.83-14.14), endotracheal tube presence (OR, 3.47; 95% CI, 1.22-9.86), and benzodiazepine administration (OR, 3.17; 95% CI, 1.28-7.81) significantly increased the odds of next-day use of physical restraints. Tracheostomy was associated with significantly lowered odds of next-day restraint use (OR, 0.13; 95% CI, 0.02-0.73). Compared with patients with a target sedation level, patients who were in a coma (OR, 2.56; 95% CI, 0.80-8.18) or deeply sedated (OR, 2.53; 95% CI, 0.91-7.08) had higher odds of next-day use of physical restraints, and agitated patients (OR, 0.08; 95% CI, 0.00-2.07) were less likely to experience restraint use.

CONCLUSION

Several potentially modifiable risk factors are associated with next-day use of physical restraints.

The PEST Model: A Quality Improvement Project to Reduce Self-extubation in the Intensive Care Unit

BACKGROUND

Self-extubation is an adverse patient event that can lead to severe complications. Gaps in clinical practice from the lack of nursing awareness and decision making capacity have often resulted in cases of preventable self-extubation. Review of current evidence suggests that initiatives to support nursing clinical decision making can help prevent adverse patient events such as self-extubation.

AIMS

The aim of this study was to reduce the incidence of self-extubation by 50% in a cardiology intensive care unit over 1 year.

METHODS

A quality improvement project was undertaken with a PEST model of nursing care introduced from January 2017 to December 2017 in the cardiology intensive care unit to guide nursing staff to assess and render appropriate interventions along patient domains such as pain, endotracheal tube securement, sedation, and tie to prevent incidences of self-extubation.

RESULTS

Incidences of self-extubation have reduced to 5 cases in 2017, reflecting a 50% improvement from 10 cases in 2016.

CONCLUSIONS

Formalizing practice standards into an easy-to-remember mnemonics or framework can improve patient outcomes. Policy makers must be aware that initiatives to facilitate decision making can improve patient safety.

Restraint in a Neurosurgical Setting: A Mixed-Methods Study

OBJECTIVE

To investigate the extent to which restraint is used in neurosurgical care, under what circumstances, and how it is documented.

METHODS

A cross-sectional study with a mixed-methods approach was used to identify neurosurgical inpatients subjected to restraint. The data were collected in 2 phases: (1) a study-specific questionnaire was distributed to nurses in which they identified if restraints had occurred during their shifts, and if so, which restraint and to which patient; and (2) scrutinizing of electronic medical records of patients identified by the questionnaires. Numeric data were analyzed using descriptive and analytic statistical methods, and textual data were analyzed using qualitative content analysis. The findings from the different data sources were compared and merged.

RESULTS

Of the 517 patients admitted to the studied department during the study period, 58 (11%) were reported to have been subjected to restraint and most of the restraining events occurred in the neurointensive care unit. Most restraint measures were not documented in the electronic medical records. The identified patients were predominantly diagnosed with traumatic brain injury or subarachnoid hemorrhage. The qualitative content analysis showed the circumstances when restraints were used: when patients were considered a danger to self or others (theme) and which symptoms and behaviors (categories) were observed in relation to the use of restraint.

CONCLUSIONS

Restraint in neurosurgical care is mostly used to prevent patients from harming themselves or others. Because of the lack of documentation, restraint measures cannot be openly assessed, thus putting patients' safety at risk.

Clinical Practice Guidelines for the Prevention and Management of Pain, Agitation/Sedation, Delirium, Immobility, and Sleep Disruption in Adult Patients in the ICU

OBJECTIVE

To update and expand the 2013 Clinical Practice Guidelines for the Management of Pain, Agitation, and Delirium in Adult Patients in the ICU.

DESIGN

Thirty-two international experts, four methodologists, and four critical illness survivors met virtually at least monthly. All section groups gathered face-to-face at annual Society of Critical Care Medicine congresses; virtual connections included those unable to attend. A formal conflict of interest policy was developed a priori and enforced throughout the process. Teleconferences and electronic discussions among subgroups and whole panel were part of the guidelines' development. A general content review was completed face-to-face by all panel members in January 2017.

METHODS

Content experts, methodologists, and ICU survivors were represented in each of the five sections of the guidelines: Pain, Agitation/sedation, Delirium, Immobility (mobilization/rehabilitation), and Sleep (disruption). Each section created Population, Intervention, Comparison, and Outcome, and nonactionable, descriptive questions based on perceived clinical relevance. The guideline group then voted their ranking, and patients prioritized their importance. For each Population, Intervention, Comparison, and Outcome question, sections searched the best available evidence, determined its quality, and formulated recommendations as "strong," "conditional," or "good" practice statements based on Grading of Recommendations Assessment, Development and Evaluation principles. In addition, evidence gaps and clinical caveats were explicitly identified.

RESULTS

The Pain, Agitation/Sedation, Delirium, Immobility (mobilization/rehabilitation), and Sleep (disruption) panel issued 37 recommendations (three strong and 34 conditional), two good practice statements, and 32 ungraded, nonactionable statements. Three questions from the patient-centered prioritized question list remained without recommendation.

CONCLUSIONS

We found substantial agreement among a large, interdisciplinary cohort of international experts regarding evidence supporting recommendations, and the remaining literature gaps in the assessment, prevention, and treatment of Pain, Agitation/sedation, Delirium, Immobility (mobilization/rehabilitation), and Sleep (disruption) in critically ill adults. Highlighting this evidence and the research needs will improve Pain, Agitation/sedation, Delirium, Immobility (mobilization/rehabilitation), and Sleep (disruption) management and provide the foundation for improved outcomes and science in this vulnerable population.

Accidental removal of devices in intensive care unit: An eight-year observational study

BACKGROUND

In the intensive care unit, invasive devices can be accidentally removed by the patient or by the operators, increasing workload, staff stress level and hospitalisation costs.

OBJECTIVE

to know the incidence of accidental removal of devices in critical patients, to identify their cause, when they occur and if they are repositioned.

METHODS

Retrospective observational study carried out in an academic, tertiary-level critical care department composed of three intensive care units. All adult patients recovered between 2011 and 2018 were enrolled. We calculated rates per 1000 device-years.

RESULTS

In the study period 10514 patients (194372 device-days) were admitted to the intensive care units and the number of reported accidental removal of devices was 451, corresponding to a rate of 2.3 episodes per 1000 device-days (95% confidence interval: 2.1-2-5). The overall rates of accidental removals were as follows: gastric tubes 10.2 (n = 270), intracranial devices 3.9 (n = 9), endotracheal tubes 2.4 (n = 27), central venous catheters and arterial catheters 1.5 (n = 92), peripheral intravenous catheters 1.2 (n = 25), surgical drains 0.5 (n = 15), urinary catheters 0.4 (n = 11), Extra Corporeal Membrane Oxygenation cannulas 0.4 (n = 1), tracheostomy cannulas 0.1 (n = 1).

CONCLUSION

Compared to the literature, this study shows fewer incidents of accidental removal of devices. The number of accidental removals could be an indicator of the quality and safety of the care.

The effect of physical restraint on neurovascular complications in intensive care units

BACKGROUND

To reduce the neurovascular complications caused by physical restraint in intensive care patients, there is a need to examine the occurrence of neurovascular complications and their rate.

OBJECTIVES

The objective of this research was to investigate the effect of physical restraint on the occurrence of neurovascular complications and their rate.

METHODS

A prospective observational cohort study was carried out. A total of 90 patients from anaesthesia and internal intensive care units participated in this study. Patients were assessed at intervals of 24 h for 4 days using the following instruments: Individual Characteristics Form, Richmond Agitation-Sedation Scale (RASS), Behavioral Pain Scale, and Complication Diagnostic Diary.

RESULTS

Redness (p < 0.001), limb movement (p < 0.001), oedema (p < 0.001), and colour complication (p < 0.001) increased, whereas pulse strength (p < 0.001) decreased in physically restrained sites on the arm from day 1 to day 4. Redness was increased in patients physically restrained with all types of materials (p < 0.001; p < 0.001; p = 0.020). Although there was a statistically significant difference in terms of movement (p = 0.006; p = 0.003) and oedema (p < 0.001; p < 0.001), both with a roll of gauze and tough cuff, these complications were not significantly different in patients restrained with green foam tie (p > 0.05). According to logistic regression analysis, material type, position of the limb, space between the physical restraint and limb, age, RASS, and pain were independent risk factors for neurovascular complications. RASS and pain were independent protective factors against movement complications.

CONCLUSIONS

The duration of physical restraint increases neurovascular complications. This study revealed that nurses did not regularly check the restrained wrist and did not focus on the peripheral circulation. It is necessary to develop training programs, standards, and appropriate follow-up strategies in intensive care units in Turkey.

Outcomes of unplanned extubation in ordinary ward are similar to those in intensive care unit: A STROBE-compliant case-control study

Unplanned extubation (UE) may cause considerable adverse effects in patients receiving mechanical ventilation (MV). Previous literature showed inconsistent prognosis in patients with UE. This study aimed to evaluate the clinical implications and outcomes of UE.The intubated adult patients with MV support in our hospital were enrolled, and they were divided into the UE and non-UE groups. Demographic data, admission unit, MV duration, overall weaning rate, and mortality rates were compared. The outcomes of UE in ordinary ward and intensive care unit (ICU) were also assessed.Totally 9245 intubated adult patients were included. UE occurred in 303 (3.5%) patients, and the UE events were 0.27 times/100 MV days. Old age, nonoperation related MV cause, and admission out of the ICU were significant factors associated with UE events. UE patients showed a trend of better overall weaning rate (71.9% vs 66.7%, P = .054) than non-UE. However, the in-hospital mortality rate (25.7% vs 24.8%, P = .713) were similar between the UE and non-UE patients. The reintubation rate of UE patients was 44.1% (142/322). Successful UEs were associated with patients in weaning process (52.8% vs 38.7%, P = .012), and patients received non-invasive positive pressure ventilation (NIPPV) support after UE (19.4% vs 3.5%, P < .001). Patients with successful UE had significantly shorter MV days, higher overall weaning rate, and lower mortality than those with unsuccessful UE. Outcomes of UE in ordinary ward and in ICU had similar MV duration, reintubation rate, overall weaning rate, and in-hospital mortality rate.The overall weaning rate and in-hospital mortality rates of the UE and non-UE patients were similar. UE occurred in ordinary ward had similar outcomes to those in ICU. Patients receiving MV should be assessed daily for weaning indications to reduce delayed extubation, and therefore, may decrease UE occurrence. Once the UE happened, NIPPV support may reduce the reintubation rate.

Self-Extubation in Patients with Traumatic Head Injury: Determinants, Complications, and Outcomes

Background

Self-extubation is a common clinical problem associated with mechanical ventilation in trauma patients worldwide.

Objectives

This study aimed to evaluate the predisposing factors, complications, and outcomes of self-extubation in patients with head injury.

Methods

This was a retrospective cohort study.

Settings

The study was conducted in a trauma intensive care unit (TICU).

Patients

All intubated patients with head injury admitted to TICU between 2013 and 2015 were included in the study.

Interventions

Planned compared to selfextubation during weaning from sedation.

Measurements

Risk, predictors, and outcomes of self-extubation were measured.

Main Results

A total of 321 patients with head injury required mechanical ventilation, of which 39 (12%) had self-extubation and 12 (30.7%) had reintubation. The median Glasgow Coma Scale, head abbreviated injury score, and injury severity score were 9, 3, and 27, respectively. The incidence of self-extubation was 0.92/100 ventilated days. Self-extubated patients were more likely to be older, develop agitation (P = 0.001), and require restraints (P = 0.001) than those who had planned extubation. Furthermore, self-extubation was associated with more use of propofol (P = 0.002) and tramadol (P = 0.001). Patients with self-extubation had higher Ramsay sedation score (P = 0.01), had prolonged hospital length of stay (P = 0.03), and were more likely to develop sepsis (P = 0.003) when compared to the planned extubation group. The overall in-hospital mortality was significantly higher in the planned extubation group (P = 0.001). Age-adjusted predictors of self-extubation were sedation use (adjusted odds ratio [aOR]: 0.06; P = 0.001), restraint use (aOR: 10.4; P = 0.001), and tramadol use (aOR: 7.21; P = 0.01).

Conclusions

More than one-tenth of patients with traumatic head injury develop self-extubation; this group of patients is more likely to have prescribed tramadol, develop agitation, and have longer hospital length of stay and less sedation use. Further prospective studies are needed to assess the predictors of self-extubation in TICU.

The Conditions for Ethical Application of Restraints

Despite the lack of evidence for the effectiveness of physical restraints, their use in patients is widespread. The best ethical justification for restraining patients is that it prevents them from harming themselves. We argue that even if the empirical evidence supported their effectiveness in achieving this aim, the use of restraints would nevertheless be unethical, so long as well-known exceptions to informed consent fail to apply. Specifically, we argue that ethically justifiable restraint use demands certain necessary and sufficient conditions. These conditions are that the physician obtained informed consent for their application, that their application be medically appropriate, and that restraints be the least liberty-restricting way of achieving the intended benefit. It is a further question whether their application is ever medically appropriate, given the dearth of evidence for their effectiveness.

Reducing Use of Restraints in Intensive Care Units: A Quality Improvement Project

BACKGROUND

Use of physical restrainst is scrutinized in intensive care units today. Usage rates for the 5 intensive care units in the Christiana Care Health Services, Newark, Delaware, were higher than the National Database of Nursing Quality Indicators mean rate of 9.61% to 15.43% for many months during fiscal years 2013 and 2014.

OBJECTIVE

To reduce and sustain the restraint rates to less than the national database mean rates for all 5 intensive care units.

METHODS

A quality improvement process was used that included forming a multiunit restraint collaborative; reviewing restraint data, including self-extubation rates; surveying staff nurses to examine alignment with evidence-based practice; and selecting a new restraint-alternative product.

RESULTS

All 5 intensive care units were able to successfully decrease restraint rates to less than the national database mean for the majority of the months since the start of the restraint collaborative in September 2012.

CONCLUSION

Use of a restraint collaborative with subsequent adoption of restraint alternatives led to a decrease in restraint rates for the 5 intensive care units to less than the national database mean, enabled sustained success, and helped align nurses' beliefs with evidence-based practice.

Investigating influencing factors of physical restraint use in China intensive care units: A prospective, cross-sectional, observational study

OBJECTIVE

In this study, we characterised the use of physical restraints in three intensive care units (ICUs) in a general hospital in Nantong, China. Additionally, we explored risk factors potentially related to physical restraint use.

BACKGROUND

Despite their numerous harmful effects, physical restraints are frequently used in ICUs worldwide. Few studies have investigated the factors that contribute to physical restraint use in Chinese hospitals.

METHODS

We conducted a prospective, cross-sectional, observational study of 312 patients in three ICUs at a general hospital in China. The quantitative data were collected during a 5-month period using a physical restraint observation form and patient records. The data obtained were analysed using descriptive statistics. The independent risk factors for physical restraint use were assessed using a logistic regression model.

RESULTS

Of the 312 patients in the three ICUs, 191 (61.2%) were restrained, and physical restraints were used more than once for 46 (24.1%) patients during their ICU stay. The median length of physical restrain use was 20 shifts (interquartile range = 10-36 shifts). Physical restraints were applied in 6664 of 12374 (53.9%) nurse shifts. The most common time at which physical restraints were applied was the beginning of the evening shift. According to the forward stepwise logistic regression analysis, delirium (P < 0.001), mechanical ventilation (P < 0.001), and age (P < 0.001) were independent risk factors for physical restraint use. The use of analgesics (P = 0.001) exerted an independent protective effect against physical restraint use.

CONCLUSIONS

The overall prevalence of physical restraint use in Chinese ICUs was higher than that reported in previous investigations. The patients' nursing notes lacked complete physical restraint records, reflecting a need for standard guidelines and policies for physical restraint use in hospital ICUs in China. In addition, in this study, we explored the risk factors related to physical restraint use and found that age, delirium, mechanical ventilation, and analgesic use are associated with physical restraint use.

Influence of physical restraint on delirium of adult patients in ICU: A nested case-control study

AIMS AND OBJECTIVES

To investigate the impact of physical restraint on delirium of adult patients in intensive care unit.

BACKGROUND

Delirium is a common clinical syndrome in intensive care unit, correlated with various adverse clinical outcomes. Physical restraint is a precipitating factor for delirium; however, the effect of physical restraint on delirium, such as duration, number and appliance is still unclear.

DESIGN

A nested case-control study.

METHODS

A cohort of 593 intensive care unit patients were observed for 12 months, and 447 of them who received physical restraint were included for analysis. Delirium was assessed using the Confusion Assessment Method for the intensive care unit. During hospitalisation in intensive care unit, newly-onset delirium patients (the delirium group), and nondelirium patients of similar age, same gender, and conditions of mechanical ventilation and sedative drug usage (the nondelirium group) were included as the matching criteria. Patient data were acquired by reviewing medical and nursing electronic records.

RESULTS

Among the 447 patients that had been physically restrained, 178 (39.8%) developed delirium. Delirium risk in patients with restraint ≥6 days was 26.30 times higher than in those <6 days. Patients who had two and three times of restraint had a 2.38-fold and 3.62-fold higher risk of delirium than those with one time of restraint. However, the appliance, site, time to apply and remove restraint had no effect on the incidence of delirium.

CONCLUSIONS

The incidence of delirium is high when patients use physical restraint. Duration and number of restraint are positively related to delirium. Restrictions on the use of restraint in intensive care unit are required to reduce the occurrence of delirium.

RELEVANCE TO CLINICAL PRACTICE

To reduce delirium risk of patients in intensive care unit, nurses need to assess the risk of physical restraint and consider alternative measures, thereby to achieve the minimisation of the use of restraint.

Impact of a Restraint Management Bundle on Restraint Use in an Intensive Care Unit

Restraint use has been linked to longer lengths of stay and other undesirable outcomes. This evidence-based project explored the impact of a restraint management bundle on restraint use, quality, and safety outcomes. Results indicated that the proportion of intensive care unit patients restrained decreased significantly (24.3% vs 20.9%) following program implementation. Project results suggest that the restraint management bundle may provide a framework for guiding the process to reduce restraint use, minimize harm, and improve patient safety.

Factors associated with unplanned extubation in the Intensive Care Unit for adult patients: A systematic review and meta-analysis

OBJECTIVES

To explore factors associated with unplanned extubation in Intensive Care Unit for adult patients.

RESEARCH METHODOLOGY

A systematic review and meta-analysis were performed of studies identified through Pubmed, CINAHL, Cochrane Library, PsycINFO and Web of Science published from initiation to September 2017. Only articles in English were included. The Newcastle-Ottawa Scale was used to evaluate the quality of the included articles.

RESULTS

Ten eligible studies were identified, encompassing a total of 2092 patients (457 in the unplanned extubation group; 1635 in the control group). The subsequent meta-analysis identified significant risk factors for unplanned extubation are male [odds ratio (OR) 1.54, 95% CI 1.12-2.12; P = 0.008], confusion [OR 0.10, 95% CI 0.05-0.17; P < 0.00001], physical restraint [OR 3.10, 95% CI 2.21-4.34; P < 0.00001], higher GCS scores [mean difference (MD) 1.06, 95% CI 0.59-1.52; P < 0.00001] and lower APACHE II scores [MD -2.26, 95% CI -3.35- -1.16; P < 0.0001]. Renal disease is a protective factor for unplanned extubation [OR 0.32, 95% CI 0.15-0.70; P = 0.004].

CONCLUSION

Patients were male, confused, having physical restraint, with higher GCS and lower APACHE II scores are significant risk factors for unplanned extubation in Intensive Care Unit adult patients.

Patient agitation and its management in adult critical care: A integrative review and narrative synthesis

AIMS AND OBJECTIVE

To critically review the evidence relating to the management of agitation within the Adult Critical Care Unit environment and identify any risks and benefits of current management strategies.

BACKGROUND

Admission to an Adult Critical Care Unit can be traumatic and potentially life altering for the patient. Patient agitation is common in Adult Critical Care Units and is associated with the potential for harm. Despite inherent safety risks, there is a paucity of evidence-based guidance underpinning the care of agitation in patients with critical illness.

STUDY DESIGN

Integrative review and narrative synthesis.

METHODS

A systematic procedure for searching and selecting the literature was followed and applied to databases including CINAHL, British Nursing Index, Cochrane Library, ProQuest, Ovid including EMBASE and MEDLINE. Selected manuscripts were analysed using a structured narrative review approach.

RESULTS

A total of 208 papers were identified and following a systematic deselection process 24 original articles were included in the review. It was identified that agitation in the setting of Adult Critical Care Unit is associated with high-risk events such as unplanned removal of life-supporting devices. There were consistent links to sepsis, previous high alcohol intake and certain medications, which may increase the development of agitation. Prompt assessment and early liberation from mechanical ventilation was a major contributing factor in the reduction in agitation. Administration of antideliriogenic mediation may reduce the need for physical restraint. There was repeated uncertainty about the role of physical restraint in developing agitation and its effective management.

CONCLUSIONS

Our review has shown that there is a dearth of research focusing on care of agitated patients in the Adult Critical Care Unit, despite this being a high-risk group. There are dilemmas for clinical teams about the effectiveness of applying physical and/or pharmacological restraint. The review has highlighted that the risk of self-extubation increases with the presence of agitation, reinforcing the need for constant clinical observation and vigilance.

RELEVANCE TO CLINICAL PRACTICE

The importance of ensuring patients are re-orientated regularly and signs of agitation assessed and acted upon promptly is reiterated. Early identification of specific patient profiles such as those with previous high alcohol or psychoactive drug habit may enable more proactive management in agitation management rather than reactive. The prompt liberation from the restriction of ventilation and encouragement of family or loved ones involvement in care need to be considered.

Risk factors for the incidence of delirium in cerebrovascular patients in a Neurosurgery Intensive Care Unit: A prospective study

AIMS AND OBJECTIVES

To explore the incidence of delirium in cerebrovascular patients admitted in our Neurosurgery Intensive Care Unit and analyse the risk factors leading to delirium.

BACKGROUND

Delirium is one of the most common mental disorders in general hospitals, but the incidence of different kinds of diseases and studies varies. Cerebrovascular patients in our Neurosurgery Intensive Care Unit are high-risk groups for delirium; identifying risk factors for delirium and taking early interventions are crucial for patient prognosis.

DESIGN

A prospective study.

METHODS

A convenience sampling method was used to collect data from 128 patients in the Neurosurgery Intensive Care Unit of Xuanwu Hospital, Capital Medical University, Beijing, China, between May 2016-January 2017. Researchers used Confusion Assessment Method for the Intensive Care Unit (Chinese version) to assess each patient's delirium statement twice a day at regular times. We also collected other independent data variables and followed up the short-term clinical outcomes daily.

RESULTS

On the basis of Confusion Assessment Method for the Intensive Care Unit evaluation, patients were divided into a delirium group and a nondelirium group. The prevalence of delirium among the 128 patients was 42.2%. Multivariate analysis showed that severity of illness, fever, the use of physical restraints and sleep deprivation were independent predictors of delirium in cerebrovascular patients in the Neurosurgery Intensive Care Unit.

CONCLUSIONS

Cerebrovascular patients in the Neurosurgery Intensive Care Unit with a critical condition, fever or use of physical restraints or experiencing sleep deprivation were more prone to delirium.

RELEVANCE TO CLINICAL PRACTICE

Cerebrovascular patients in the Neurosurgery Intensive Care Unit showed a high incidence of delirium. There are many risk factors leading to delirium, some of which are independent predictors of intensive care delirium. Patients with delirium will suffer various adverse effects upon their short-term clinical outcomes. Therefore, nurses should pay close attention to changes in a patient's mental state and learn about the risk factors associated with delirium, in order to be able to take early measures to prevent delirium.
