The principles of physical restraint use for hospitalized elderly people: an integrated literature review

Is physical restraint unethical and illegal?: a qualitative analysis of Korean written judgments

BACKGROUND

Physical restraint (PR) is used to ensure the safety of care recipients. However, this causes an ethical dilemma between the autonomy and dignity of the recipients and the provision of effective treatment by health workers. This study aimed to analyze legal and ethical situations related to the use of PR using written judgments.

METHODS

This study uses a qualitative retrospective design. Qualitative content analysis was performed on South Korean written judgments. A total of 38 cases from 2015 to 2021 were categorized. The types of court decisions and ethical dilemma situations were examined according to the four principles of bioethics, and the courts' judgments were compared.

RESULTS

Written judgments related to PR were classified into three types according to the appropriateness of PR use, the presence or absence of duty of care, and legal negligence. Ethical dilemmas were categorized into three situations depending on whether the four principles of bioethics were followed. The courts' decisions regarding the ethical dilemmas differed depending on the situational factors before and after the use of PR and the conflicting conditions of the ethical principles.

CONCLUSIONS

Health workers should consider legal and ethical requirements when determining whether to use PR to provide the care recipient with the necessary treatment.

[Nursing Students' Experiences of Observing the Use of Physical Restraints: A Qualitative Study]

PURPOSE

The purpose of this study was to understand the experiences of final-year undergraduate nursing students in observing the use of physical restraints on patients in the course of clinical practice.

METHODS

Three focus group interviews were conducted with 12 Korean nursing students who could provide sufficient information about their observation of physical restraints. The collected data was analyzed through conventional content analysis.

RESULTS

The data were classified into four theme clusters, and nine themes. The four theme clusters included 'recognized as an unavoidable means,' 'experienced problems with the use of physical restraints,' 'realized the importance of the nurse's role and efforts,' and 'aspire to learn about correct use of physical restraints.' While nursing students recognized the necessities and problems of using physical restraints in clinical practice, and the importance of nurses' role and effort, the results found that education related to the use of physical restraints should be more systematic within the nursing curriculum.

CONCLUSION

This study highlights the necessity of educating nursing students to ensure they acquire accurate knowledge and awareness regarding the use of physical restraints, and suggests the inclusion of systematic guidelines through simulation or extracurricular activities.

Physical restraint in older people: a statement from the Early Career Network of the International Psychogeriatric Association

The International Psychogeriatric Association (IPA) has expressed significant concerns over the use of physical restraints in older people across diverse aged care settings. Following an extensive analysis of the available literature, the IPA's Early Career Network (ECN) has formulated a collection of evidence-based recommendations aimed at guiding the use of physical restraints within various care contexts and demographic groups. Physical restraints not only infringe upon human rights but also raise significant safety concerns that adversely impact the physical, psychological, social, and functional well-being of older adults. Furthermore, their effectiveness in geriatric settings remains inadequate. Given these considerations, the IPA and its ECN firmly assert that the use of physical restraints should only be considered as a final recourse in the care of older people.

Machine learning for prediction of delirium in patients with extensive burns after surgery

AIMS

Machine learning-based identification of key variables and prediction of postoperative delirium in patients with extensive burns.

METHODS

Five hundred and eighteen patients with extensive burns who underwent surgery were included and randomly divided into a training set, a validation set, and a testing set. Multifactorial logistic regression analysis was used to screen for significant variables. Nine prediction models were constructed in the training and validation sets (80% of dataset). The testing set (20% of dataset) was used to further evaluate the model. The area under the receiver operating curve (AUROC) was used to compare model performance. SHapley Additive exPlanations (SHAP) was used to interpret the best one and to externally validate it in another large tertiary hospital.

RESULTS

Seven variables were used in the development of nine prediction models: physical restraint, diabetes, sex, preoperative hemoglobin, acute physiological and chronic health assessment, time in the Burn Intensive Care Unit and total body surface area. Random Forest (RF) outperformed the other eight models in terms of predictive performance (ROC:84.00%) When external validation was performed, RF performed well (accuracy: 77.12%, sensitivity: 67.74% and specificity: 80.46%).

CONCLUSION

The first machine learning-based delirium prediction model for patients with extensive burns was successfully developed and validated. High-risk patients for delirium can be effectively identified and targeted interventions can be made to reduce the incidence of delirium.

Association of physical restraint duration and undesirable outcomes amongst inpatients comorbid with dementia and pneumonia in acute care settings

AIMS AND OBJECTIVES

This study aimed to examine the association between physical restraint duration and undesirable outcomes amongst inpatients comorbid with dementia and pneumonia in acute care hospitals.

BACKGROUND

Physical restraints are frequently used in the management of patients, especially amongst patients with dementia. No previous study investigated the potential undesirable effects of physical restraints in patients with dementia.

METHODS

This was a cohort study using a nationwide discharge abstract database in Japan. Patients aged ≥65 years with dementia hospitalised for pneumonia or aspiration pneumonia between April 1, 2016 and March 31, 2019 were identified. The exposure was physical restraint. The primary outcome was hospital discharge to the community. Secondary outcomes included hospitalisation costs, functional decline, in-hospital mortality, and institutionalisation for long-term care.

RESULTS

A total of 18,255 inpatients with pneumonia and dementia in 307 hospitals were included in this study. Of them, 21.5% and 23.7% had physical restraint during full and partial days of hospital stays, respectively. Discharge to the community incidence rates was lower in the full-restraint vs. the no-restraint group (27 vs. 29 per 1000 person-days; HR, 1.05 [95% CI, 1.01-1.10]) and the partial-restraint vs. the no-restraint group (17 vs. 29 per 1000 person-days; HR, 1.79 [95% CI, 1.71-1.87]). The risks of functional decline were higher in the full-restraint vs. the no-restraint group (27.8% vs. 20.8%; RR, 1.33 [95% CI, 1.22, 1.46]) and the partial-restraint vs. the no-restraint group (29.2% vs. 20.8%; RR, 1.40 [95% CI, 1.29, 1.53]).

CONCLUSIONS

The use of physical restraints was associated with a lower incidence rate of discharge to the community and an increased risk of functional decline at discharge. Further research is needed to judge the benefit-risk balance of physical restraints in acute care settings.

RELEVANCE TO CLINICAL PRACTICE

Understanding the risk of physical restraints allows medical staff to improve the process of decision making in everyday practice. No Patient or Public Contribution.

A Risk Prediction Model for Physical Restraints Among Older Chinese Adults in Long-term Care Facilities: Machine Learning Study

BACKGROUND

Numerous studies have identified risk factors for physical restraint (PR) use in older adults in long-term care facilities. Nevertheless, there is a lack of predictive tools to identify high-risk individuals.

OBJECTIVE

We aimed to develop machine learning (ML)-based models to predict the risk of PR in older adults.

METHODS

This study conducted a cross-sectional secondary data analysis based on 1026 older adults from 6 long-term care facilities in Chongqing, China, from July 2019 to November 2019. The primary outcome was the use of PR (yes or no), identified by 2 collectors' direct observation. A total of 15 candidate predictors (older adults' demographic and clinical factors) that could be commonly and easily collected from clinical practice were used to build 9 independent ML models: Gaussian Naïve Bayesian (GNB), k-nearest neighbor (KNN), decision tree (DT), logistic regression (LR), support vector machine (SVM), random forest (RF), multilayer perceptron (MLP), extreme gradient boosting (XGBoost), and light gradient boosting machine (Lightgbm), as well as stacking ensemble ML. Performance was evaluated using accuracy, precision, recall, an F score, a comprehensive evaluation indicator (CEI) weighed by the above indicators, and the area under the receiver operating characteristic curve (AUC). A net benefit approach using the decision curve analysis (DCA) was performed to evaluate the clinical utility of the best model. Models were tested via 10-fold cross-validation. Feature importance was interpreted using Shapley Additive Explanations (SHAP).

RESULTS

A total of 1026 older adults (mean 83.5, SD 7.6 years; n=586, 57.1% male older adults) and 265 restrained older adults were included in the study. All ML models performed well, with an AUC above 0.905 and an F score above 0.900. The 2 best independent models are RF (AUC 0.938, 95% CI 0.914-0.947) and SVM (AUC 0.949, 95% CI 0.911-0.953). The DCA demonstrated that the RF model displayed better clinical utility than other models. The stacking model combined with SVM, RF, and MLP performed best with AUC (0.950) and CEI (0.943) values, as well as the DCA curve indicated the best clinical utility. The SHAP plots demonstrated that the significant contributors to model performance were related to cognitive impairment, care dependency, mobility decline, physical agitation, and an indwelling tube.

CONCLUSIONS

The RF and stacking models had high performance and clinical utility. ML prediction models for predicting the probability of PR in older adults could offer clinical screening and decision support, which could help medical staff in the early identification and PR management of older adults.

Chemical and physical restraint use during acute care hospitalization of older adults: A retrospective cohort study and time series analysis

Background

Chemical and physical restraints are associated with harm in older adults, but our understanding of their use during acute care hospitalizations is limited.

Objectives

To (1) describe restraint use during acute care hospitalizations of older adults at the onset of the COVID-19 pandemic compared to pre-pandemic levels and (2) describe between-hospital variability in restraint use.

Design

Retrospective cohort study with a time series analysis.

Participants

Acute care hospital inpatients, aged 65 years or older, who were discharged from one of four Alberta hospitals or six Ontario hospitals in Canada, between November 1, 2019, and June 30, 2020.

Main measures

We used autoregressive linear models with restricted cubic splines to compare proportions of chemical restraint (that is, psychotropic medications, namely antipsychotics, benzodiazepines, and trazodone) and physical restraint (e.g., mittens) use immediately after the onset of the COVID-19 pandemic with pre-pandemic levels. We describe between-hospital variability in restraint use using intraclass correlation coefficients (ICC) and median odds ratios (OR).

Key results

We included 71,004 hospitalizations. Adjusted for the prevalence of dementia and psychotic disorders, chemical restraint use increased in Ontario hospitals from a pre-pandemic average of 27.1% to 30.8% (p<0.001) before returning to pre-pandemic levels within eight weeks. Physical restraint orders in Ontario increased from 5.9% to 8.3% (p = 0.012) and remained elevated at eight weeks. No significant changes in restraint use were observed in Alberta. There was moderate between-hospital variability in chemical restraint use (ICC 0.041 and median OR 1.43). Variability in physical restraint use was higher (ICC 0.11 and median OR 1.83).

Conclusions

The COVID-19 pandemic impacted in-hospital use of chemical and physical restraints among older adults in Ontario but not Alberta. Substantial differences in chemical and physical restraint use by region and hospital suggests there are opportunities to improve best practices in geriatric care. Future research must support implementation of evidence-informed interventions that standardize appropriate restraint use.

Attitudes of Nursing Staff in Hospitals towards Restraint Use: A Cross-Sectional Study

The attitude of nursing staff towards restraint use can be decisive for whether restraints are used. So far, nursing staff’s attitudes have been studied primarily in long-term and mental health care settings, while findings from somatic acute care hospital settings are largely lacking. Therefore, we aimed to investigate (a) the attitudes of hospital nursing staff towards restraint use, and (b) the construct validity and reliability of a measurement instrument for use in hospital settings that was developed and validated in long-term care settings (Maastricht Attitude Questionnaire (MAQ)). Using a cross-sectional design, the attitudes of 180 nursing staff towards restraint use were assessed. The data were analysed descriptively and by means of regression analysis and factor analysis. We found that nursing staff in hospitals have a neutral attitude towards restraint use and that the MAQ, with minor adaptations, can be used in hospital settings, although further testing is recommended. Neutral attitudes of nursing staff have also been observed in long-term and mental health care settings, where changing attitudes were found to be challenging. Interventions at the national level (e.g., legal regulations) and management level (e.g., providing alternatives and changing institutional culture) are suggested.
