Development and experimental validation of computational methods for human antibody affinity enhancement.

High affinity is crucial for the efficacy and specificity of antibody. Due to involving high-throughput screens, biological experiments for antibody affinity maturation are time-consuming and have a low success rate. Precise computational-assisted antibody design promises to accelerate this process, but there is still a lack of effective computational methods capable of pinpointing beneficial mutations within the complementarity-determining region (CDR) of antibodies. Moreover, random mutations often lead to challenges in antibody expression and immunogenicity. In this study, to enhance the affinity of a human antibody against avian influenza virus, a CDR library was constructed and evolutionary information was acquired through sequence alignment to restrict the mutation positions and types. Concurrently, a statistical potential methodology was developed based on amino acid interactions between antibodies and antigens to calculate potential affinity-enhanced antibodies, which were further subjected to molecular dynamics simulations. Subsequently, experimental validation confirmed that a point mutation enhancing 2.5-fold affinity was obtained from 10 designs, resulting in the antibody affinity of 2 nM. A predictive model for antibody-antigen interactions based on the binding interface was also developed, achieving an Area Under the Curve (AUC) of 0.83 and a precision of 0.89 on the test set. Lastly, a novel approach involving combinations of affinity-enhancing mutations and an iterative mutation optimization scheme similar to the Monte Carlo method were proposed. This study presents computational methods that rapidly and accurately enhance antibody affinity, addressing issues related to antibody expression and immunogenicity.

Human Rights in Hospitals: an End to Routine Shackling.

Medical students (NSB, NM, JDW) spearheaded revision of the policy and clinical practice for shackling incarcerated patients at Boston Medical Center (BMC), the largest safety net hospital in New England. In American hospitals, routine shackling of incarcerated patients with metal restraints is widespread-except for perinatal patients-regardless of consciousness, mobility, illness severity, or age. The modified policy includes individualized assessments and allows incarcerated patients to be unshackled if they meet defined criteria. The students also formed the Stop Shackling Patients Coalition (SSP Coalition) of clinicians, public health practitioners, human rights advocates, and community members determined to humanize the inpatient treatment of incarcerated patients. Changes pioneered at BMC led the Mass General Brigham health system to follow suit. The Massachusetts Medical Society adopted a resolution authored by the SSP Coalition, which condemned universal shackling and advocated for use of the least restrictive alternative. This will be presented to the American Medical Association in June 2024. The Coalition led a similar effort to coauthor a policy statement on the issue, which was formally adopted by the American Public Health Association in November 2023. Most importantly, in an unprecedented human rights victory, a BMC patient who was incarcerated, sedated, and intubated was unshackled by correctional officers for the purpose of preserving human dignity.

User-driven instructions reduce errors in child restraint use: a randomised controlled trial in Sydney, Australia.

BACKGROUND AND OBJECTIVES: Crash injury risk is reduced when a child correctly uses an appropriate restraint; however, incorrect restraint use remains widespread. The aim of this study was to determine whether product information developed using a user-driven approach increases correct child restraint use. METHODS: We conducted a two-arm double-blinded parallel randomised controlled trial in New South Wales, Australia 2019-2021. Participants were current drivers who were either an expectant parent or a parent of at least one child residing in the greater Sydney metropolitan area who were interested in purchasing a new child restraint. The intervention was user-driven product information consisting of instructions printed on an A3 sheet of paper, swing tags with key reminders and a video accessed via Quick Response codes printed on the materials. The control group received a postcard summarising legal child restraint requirements. The primary outcome was the correctness of child restraint use observed during home visit approximately 6 months after restraint purchase. Correct use was defined as no serious error or <2 minor errors. The secondary outcome was a count of observed errors. RESULTS: 427 participants were recruited. Home visits were conducted for 372 (190 intervention and 182 control). Correct use was more common in the intervention group (37.4%) compared with the control group (24.2%, p=0.006). Participants receiving the intervention were 1.87 times more likely to correctly use their restraint than those in the control group (95% CI 1.19 to 2.93). CONCLUSIONS: The results provide evidence for the effectiveness of user-driven instructions as a countermeasure to restraint misuse. TRIAL REGISTRATION NUMBER: ACTRN12617001252303.

Updated population-level estimates of child restraint practices among children aged 0-12 years in Australia, 10 years after introduction of age-appropriate restraint use legislation.

OBJECTIVE: Optimal child passenger protection requires use of a restraint designed for the age/size of the child (appropriate use) that is used in the way the manufacturer intended (correct use).This study aimed to determine child restraint practices approximately 10 years after introduction of legislation requiring correct use of age-appropriate restraints for all children aged up to 7 years. METHODS: A stratified cluster sample was constructed to collect observational data from children aged 0-12 years across the Greater Sydney region of New South Wales (NSW). Methods replicated those used in a similar 2008 study. Population weighted estimates for restraint practices were generated, and logistic regression used to examine associations between restraint type, and child age with correct use accounting for the complex sample. RESULTS: Almost all children were appropriately restrained (99.3%, 95% CI 98.4% to 100%). However, less than half were correctly restrained (no error=27.3%, 95% CI 10.8% to 43.8%, no serious error=43.8%, 95% CI 35.0% to 52.7%). For any error, the odds of error decreased by 39% per year of age (OR 0.61, 95% CI 0.46 to 0.81) and for serious error by 25% per year (OR 0.75, 95% CI 0.60 to 0.93). CONCLUSION: The findings demonstrate high levels of appropriate restraint use among children across metropolitan Sydney approximately 10 years after introduction of legislation requiring age-appropriate restraint use until age 7, however, errors in the way restraints remain common. IMPLICATIONS FOR PUBLIC HEALTH: Given the negative impact incorrect use has on crash protection, continuing high rates of incorrect use may reduce effectiveness of legislative change on injury reduction.

Comparative analysis of child injuries in passenger vehicles and school buses: a multicentre cross-sectional study.

OBJECTIVE: This study investigated the differences in injury profiles and safety device effectiveness among children with road traffic injuries (RTIs) involving passenger vehicles and school buses. METHODS: Using data from the Emergency Department-based Injury In-depth Surveillance database, this multicentre cross-sectional study investigated the injury profiles of 14 669 children aged 12 years old and younger who experienced RTIs from 2011-2021. Demographic factors, injury distribution, severity and effect of safety device use between RITs involving passenger vehicles and school buses were compared. RESULTS: RTIs in children most frequently occurred between 12:00 and 18:00 hours (46.9%). School bus-related RTIs peaked during school commute hours, that is, from 06:00 to 12:00 hours, and were associated with a higher prevalence of head (63.1% vs 58.9%, p<0.05) and extremity injuries (upper extremity: 8.0% vs 6.4% and lower extremity: 11.1% vs 7.6 %, p<0.05) compared with those involving passenger vehicles. However, passenger vehicle crashes showed higher proportions of neck and chest injuries, along with injuries requiring hospitalisation and intensive care. Safety devices exhibited preventive effects against head and lower extremity injuries in both vehicle types. While safety devices showed effective in reducing hospital admissions and severe injuries in passenger vehicles, their effectiveness in school buses was not observed. CONCLUSION: This study highlights the different epidemiology and injury profiles of RTIs among children involving passenger vehicles and school buses. Improved safety devices, particularly in school buses, are necessary to ensure the comprehensive protection of child passengers and reduce the risk of severe injuries during road traffic incidents.

Evaluation of a distribution, education and awareness intervention for child passenger safety in Lebanon: a low-income and middle-income country setting.

BACKGROUND: The Eastern Mediterranean Region suffers disproportionately from paediatric traffic-related injuries. Despite governmental laws, Lebanon-an eastern Mediterranean country-has low child restraint (CR) use prevalence. This study examined the impact of using car seat distribution, and child passenger safety education and awareness intervention to improve child passenger safety knowledge and practices among caregivers. METHODS: This study recruited Lebanese caregivers with one child or more, using a 4-wheel motor vehicle, and not using a car seat. The intervention comprised an educational session followed by a car seat or booster seat distribution and installation check by a certified child passenger safety technician. A baseline assessment questionnaire was used to identify reasons for prior CR non-use. A child passenger safety knowledge test was administered before, immediately after and 3 months postintervention to assess child passenger safety knowledge retention and compare it to the baseline using the conditional logit model for pre-post interventions. RESULTS: Fifty-eight participants underwent the intervention. Affordability was identified as the primary reason for car seat non-use. Three months after the intervention, compliance with CRs use was reported at 100%, and correct responses on the knowledge test significantly increased (p<0.05) for all items except for harness tightness (p=0.673). CONCLUSION: Our child passenger safety intervention resulted in improved knowledge and increased self-reported use of CRs in a caregivers' cohort in Lebanon. Further efforts should address sociocultural and economic barriers and the lack of local child passenger safety technicians to mitigate the region's paediatric road traffic injury and death toll.

Australian parental decisions about transitioning children from booster seats in a randomised trial: greater support may be needed.

BACKGROUND: Premature graduation to an adult seatbelt is common and detrimental to optimal crash protection. While there is an existing tool (the 5-step test) to support a parent's decision to graduate their child, its effectiveness is unknown. The aim of this study was to evaluate the 5-step test. METHOD: A randomised controlled design was used. Participants were parents of children aged 7-12 years. After exposure to information about the 5-step test or control material, participants assessed belt fit in three seating conditions and 'thought aloud' while making their assessment. Seating conditions provided a good, poor and partially good seatbelt fit based on the child's anthropometry. Participants were also assessed on their knowledge of good seatbelt fit criteria. RESULTS: Participants exposed to the 5-step test (n=18) had significantly improved their knowledge of the criteria required to achieve good seatbelt with, on average, 1.0 higher score in the 6-point assessment (95% CI 0.23 to 1.7, p=0.012) than those in the control group. There was also a greater percentage of participants in this group (44.4% intervention vs 27.8% control) who made accurate decisions about seatbelt fit, but this difference did not reach significance (OR 2.08, 95% CI 0.52 to 8.34). CONCLUSION: The results demonstrate that the 5-step test is effective in improving knowledge but are inconclusive about its effectiveness in promoting accurate decision-making. However, the proportion of participants making accurate decisions in the intervention group remained low. This suggests that parents may require greater assistance than what is currently provided.

Surveillance methods and interventions implemented in American Indian and Alaska Native communities to increase child restraint device and seat belt use in motor vehicles: a systematic review.

BACKGROUND: American Indian/Alaska Native (AI/AN) children are disproportionately affected by injuries and deaths related to motor vehicle crashes. We aimed to synthesise published evidence on surveillance methods and interventions implemented in AI/AN communities and analyse characteristics that make them successful in increasing child restraint devices and seat belt use. METHODS: Studies were collected from the PubMed, Scopus, and TRID databases and the CDC Tribal Road Safety website, Community Guide, and Indian Health Service registers. Included studies collected primary data on AI/AN children (0-17) and reported morbidity/mortality outcomes related to child restraint devices or seat belt use. Studies with poor methodological quality, published before 2002, whose data were collected outside of the USA, or were non-English, were excluded. Checklists from the Joanna Briggs Institute were used to assess the risk of bias. In the synthesis of results, studies were grouped by whether a surveillance method or intervention was employed. RESULTS: The final review included 9 studies covering 72 381 participants. Studies conducted surveillance methods, interventions involving law enforcement only and multipronged interventions. Multipronged approaches were most effective by using the distribution of child restraint devices combined with at least some of the following components: educational programmes, media campaigns, enactment/enforcement of child passenger restraint laws, incentive programmes and surveillance. DISCUSSION: Although this review was limited by the number and quality of included studies, available resources suggest that we need multipronged, culturally tailored and sustainable interventions fostered by mutually beneficial and trusting partnerships. Continued investment in AI/AN road safety initiatives is necessary.

Using a Behavior Assessment Tool to Decrease Restraint Use in the Emergency Department.

INTRODUCTION: Behavioral health visits to emergency departments have increased, increasing the risk of patient violent agitation that may require restraints to control. Our objective was to determine whether using the Behavioral Activity Rating Scale and treatment recommendations matched to patient scores would affect the number of patients who required physical restraints during their stay in the emergency department. METHODS: In this quality improvement project, nursing performed Behavioral Activity Rating Scale assessments on all behavioral health patients who presented to the emergency department, occurring during triage and at regular intervals with vital signs. Data were collected for a period before implementation and compared with data collected after implementing the Behavioral Activity Rating Scale workflow. Patients who required restraints during their stay, patients who required 2 or more restraints during their stay, and timing of restraint application were analyzed. RESULTS: Results show a decrease in the number of patients who required restraints during their ED stay, decreasing from a rate of 8.7% to 7.0% (P = .02). There was also a decrease in the number of patients who required multiple restraints, from a rate of 82.2% to 27.2% (P < .001). There was no difference in the number of patients who required restraints 1 hour after their arrival before versus after intervention (P = .40). DISCUSSION: Early recognition of patient agitation is essential in appropriate treatment of that agitation. The Behavioral Activity Rating Scale assessment is an effective tool to quantify a patient's agitation level. When coupled with treatment recommendations or protocols, it may decrease restraint use in the emergency department.

Assessment of Nurses' Knowledge, Attitude and Practice Regarding Physical Restraint: A Scoping Review.

The use of physical restraints (PR) in healthcare settings, especially in psychiatric units, is a controversial topic. The attitude, knowledge, and practices of nurses towards PR can influence its application, which raises concerns about the balance between patient safety and individual rights. With mental disorders being a leading cause of disability globally, understanding the complexities surrounding PR use becomes paramount. A comprehensive literature review was conducted using multiple databases, including PubMed, Medline, CINAHL, PsycINFO, ProQuest, The Cochrane Library, the Saudi Digital Library, and Google Scholar. The search spanned literature published up to December 2022, focusing on studies that explored the relationship between nurses' knowledge, attitudes, and practices regarding PR in psychiatric settings. Inclusion and exclusion criteria were applied to filter out relevant studies. From 220 records initially retrieved, 12 articles were identified for the final review. The reviewed studies highlighted a moderate knowledge and attitude among nurses concerning PR. Many nurses were found to be uncertain about the reasons for PR application and its alternatives. Educational interventions were emphasized in several studies as beneficial in improving nurses' knowledge, attitudes, and practices. However, inconsistencies were observed regarding the impact of these interventions on nurses' attitudes. Experience, higher education, and continuous training sessions were found to be correlated with better knowledge and more favourable attitudes towards PR. This review emphasizes the critical need for consistent training and education for nurses regarding PR, given the profound implications for patient care and safety. While educational interventions show promise in enhancing knowledge and practice, their impact on attitudes remains contested. Future research should consider the gaps identified in this review, including the exploration of alternatives to PR, larger sample sizes and longitudinal studies to understand the long-term effects of interventions.

NMR detection and conformational dependence of two, three, and four-bond isotope shifts due to deuteration of backbone amides.

NMR isotope shifts occur due to small differences in nuclear shielding when nearby atoms are different isotopes. For molecules dissolved in 1:1 H2O:D2O, the resulting mixture of N-H and N-D isotopes leads to a small splitting of resonances from adjacent nuclei. We used multidimensional NMR to measure isotope shifts for the proteins CUS-3iD and CspA. We observed four-bond 4∆N(ND) isotope shifts in high-resolution 2D 15N-TROSY experiments of the perdeuterated proteins that correlate with the torsional angle psi. Three-bond 3∆C'(ND) isotope shifts detected in H(N)CO spectra correlate with the intraresidue H-O distance, and to a lesser extent with the dihedral angle phi. The conformational dependence of the isotope shifts agree with those previously reported in the literature. Both the 4∆N(ND) and 3∆C'(ND) isotope shifts are sensitive to distances between the atoms giving rise to the isotope shifts and the atoms experiencing the splitting, however, these distances are strongly correlated with backbone dihedral angles making it difficult to resolve distance from stereochemical contributions to the isotope shift. H(NCA)CO spectra were used to measure two-bond 2∆C'(ND) isotope shifts and [D]/[H] fractionation factors. Neither parameter showed significant differences for hydrogen-bonded sites, or changes over a 25° temperature range, suggesting they are not sensitive to hydrogen bonding. Finally, the quartet that arises from the combination of 2∆C'(ND) and 3∆C'(ND) isotope shifts in H(CA)CO spectra was used to measure synchronized hydrogen exchange for the sequence neighbors A315-S316 in the protein CUS-3iD. In many of our experiments we observed minor resonances due to the 10% D2O used for the sample deuterium lock, indicating isotope shifts can be a source of spectral heterogeneity in standard NMR experiments. We suggest that applications of isotope shifts such as conformational analysis and correlated hydrogen exchange could benefit from the larger magnetic fields becoming available.

Randomised feasibility trial of a virtual intervention to address infant car seat misuse.

BACKGROUND: Serious car seat installation errors occur at high rates in infants and children. These errors significantly increase the risk of child injury in a motor vehicle crash, and few interventions have addressed the challenge longitudinally. METHODS: This was a pilot randomised controlled feasibility trial of virtual car seat safety checks for caregivers of newborns recruited from an urban newborn nursery. The control (enhanced usual care (EUC)) group received an in-person car seat check as a newborn and virtual check at 9 months. The intervention group received two additional virtual checks at 3 and 6 months. Installation and infant positioning errors were documented and corrected by a child passenger safety technician (CPST). We measured feasibility and acceptability by tracking caregiver and CPST challenges, and caregiver retention. Group differences were tested for statistical significance using χ2 or Fisher's exact test for categorical variables, and two sample t-tests for continuous variables. RESULTS: 33 caregivers were randomised to the EUC and 28 to the intervention group. Virtual checks were feasible, with variable participation levels at each quarter. Wi-Fi and app challenges noted in 30%. There was satisfaction with the virtual car seat checks. At baseline, car seat installation and infant positioning errors occurred at equal frequency, and at 9 months the intervention group had a significantly lower mean proportion than the EUC group in all categories of errors. In summary, virtual seat checks are feasible and the optimal timing of repeat checks requires additional study. A larger study is needed to further evaluate the effect of longitudinal virtual checks on errors.

Retrospective evaluation of ketamine versus droperidol on time to restraint removal in agitated emergency department patients.

PURPOSE: Acute agitation and violent behavior in the emergency department (ED) can lead to significant patient morbidity and contribute to the growing problem of workplace violence against health care providers. To our knowledge, there is no available literature directly comparing intramuscular ketamine to intramuscular droperidol in ED patients presenting with undifferentiated agitation. The purpose of this investigation was to compare the effectiveness and safety of these agents for acute agitation in the ED. METHODS: This was a retrospective observational study conducted at an urban, academic ED. The primary endpoint was time from the first dose of study medication to restraint removal. Safety endpoints included incidence of bradycardia (heart rate < 60 bpm), hypotension (systolic blood pressure < 90 mmHg), hypoxia (oxygen saturation < 90% or need for respiratory support), and incidence of intubation for ongoing agitation or respiratory failure. RESULTS: An initial 189 patients were screened, of which, 92 met inclusion criteria. The median time from initial drug administration to restraint removal was 49 min (IQR 30, 168) in the ketamine group and 43 min (IQR 30, 80) in the droperidol group (Median difference 6 min; 95% CI [-7, 26]). There was no significant difference in rates of bradycardia (3% vs 3%, 95% CI [-7%, 8%]), hypotension (0% vs 2%, 95% CI [-5%, 2%]), or hypoxia (7% vs 10%, 95% CI [-15%, 9%]) in the ketamine versus droperidol groups respectively. One patient in the ketamine group was intubated for ongoing agitation, and one patient in the droperidol group was intubated for respiratory failure. CONCLUSIONS: Intramuscular droperidol and intramuscular ketamine were associated with similar times from drug administration to restraint removal in patients presenting to the ED with undifferentiated agitation. Prospective studies are warranted to evaluate IM droperidol and IM ketamine head-to-head as first line agents for acute agitation in the ED.

A comprehensive examination of research instruments utilized for assessing the attitudes of healthcare professionals towards the use of restraints in mental healthcare: A systematic review.

AIM: This systematic review aimed to identify, describe and evaluate questionnaires measuring health professionals' attitudes towards restraints in mental healthcare. DESIGN: A systematic review was undertaken in accordance with the COSMIN protocol for systematic review and the relevant sections of the 2020 Preferred Reporting Items for Systematic Reviews and Meta-Analyses. DATA SOURCES: OVID Medline, OVID nursing, Psychinfo, Embase and Cinahl were systematically searched from databases inception, with an initial search in December 2021 and updated in April 2022. REVIEW METHODS: The inclusion criteria compromised articles reporting on self-reported instruments of attitudes or perceptions, development or validation of instruments and the evaluation of one or more measurement properties. Articles using multiple instruments in one study or not published in English were excluded. Two researchers independently extracted the data and appraised the methodological quality using the COSMIN guidelines and standards (consensus-based standards for the selection of health measurement instrument). A narrative synthesis without meta-analysis was performed. The systematic review was registered in PROSPERO Protocol ID CRD42022308818. RESULTS: A total of 23 studies reporting ten instruments were included. The findings revealed a broad variation in the content of the questionnaires, the use of terms/constructs and the context in which the various instruments measure attitudes towards coercive measures. Many studies lacked sufficient details on report of psychometric properties. Finally, the results were not summarized and the evidence not GRADED. CONCLUSIONS: There is a need for updated and adapted instruments with origins in theory and clear joint definitions such that attitudes towards coercive measures can be reliably assessed regarding the validity and reliability of instruments, which will be of importance to facilitate the use of instruments in research and clinical settings. IMPACT: Reviews addressing surveys, self-reported attitudes towards restraints in mental healthcare and examination of psychometric properties seem limited. We highlight distinct complexity, psychometric limitations and broad variation in the context and content measuring attitudes towards coercive measures, and their various use of terms/constructs in the existing questionnaires. These findings contribute to further research regarding the development of questionnaires and the need of representing the concept well - carefully denoted by the indicators, likewise the importance of applying questionnaires with properly reported measurement properties in terms of validity and reliability to ensure the use in research and clinical settings.

Use of physical restraints and its associated risk factors in the aged care facilities: A multicentre cross-sectional study.

AIMS AND OBJECTIVES: To investigate the use of physical restraints in aged care facilities(ACFs)and analyse its associated risk factors. BACKGROUND: Physical restraints have been widely used in ACFs worldwide, but they can cause physical and mental harm to older people. It is important to regulate the use of physical restraint. DESIGN: A cross-sectional observational and correlational multicentre study. METHODS: By convenience sampling method, we selected eight ACFs in four representative regions of Hunan province, China, for this study. The ACF-related information was obtained by interviewing the managers and reviewing records. We conducted investigation and observation on the elderly in the ACFs to understand the use of physical restraints at three different times: 9:30-11:30, 16:00-18:00 and 19:30-21:30 on a working day. The STROBE checklist was followed for this cross-sectional study. RESULTS: This study found that the utilisation rate of physical restraints was 23.2%. The critical risk factors affecting the use of physical restrains include the following: (1) the ratio of nursing staff to the elderly residents; (2)whether there is a dementia care unit at the facility; (3) the number of elderly residents in each room; (4) the elderly residents' age, degree of education, marital status, care dependence and cognitive impairment; (5) whether the elderly has suffered from a stroke or senile dementia; (6) whether the elderly carries medical catheters. CONCLUSION: There is a lack of standardisation in the use of physical restraints in ACFs of central China. Chinese ACFs should develop guidelines and reduction measures to standardise the use of physical restraints, basing on the key factors affecting the use of physical restraints. RELEVANCE TO CLINICAL PRACTICE: The use of physical restraints in ACFs is threatening the safety of the elderly residents. Understanding the implementation of physical restraint in ACFs can provide reference for reducing the use of physical restraint.

Exploring the ethics of physical restraints: Students' questioning.

BACKGROUND: Physical restraints are routinely employed to ensure patient safety in Japanese acute care. Little is known about nursing students' perspectives and how they begin to question their value and knowledge in the face of restraint experiences in clinical practice. OBJECTIVE: To investigate nursing students' questions about patient restraints and how they understand the ethics of the use of restraints in nursing. RESEARCH DESIGN: Qualitative descriptive research using narrative analysis. PARTICIPANTS AND RESEARCH CONTEXT: Experiential data were generated and thematically analyzed from semi-structured interviews with 16 nursing students who had completed their bachelor's degree program requirements. ETHICAL CONSIDERATIONS: The study was approved by academic and clinical ethics agencies. Participants provided written informed consent. RESULTS: Physical restraints were encountered in 16 incidents, 3 with children and 13 with older patients with dementia. Students struggled to comprehend the policies and protocols of restraint use and worried their use was primarily for security rather than therapeutic purposes. Five themes were identified: (1). Questioning the tension between person-centered care, patient autonomy, and restraints, (2). Questioning the nature of restraints in which participants analyzed the policies and protocols around restraint use, (3). Questioning the professional nursing self whereby students reflected on how restraint use challenged their nursing values, and (4). Questioning professional nursing practice, in which students explored how restraints fit within a nursing perspective and positioned themselves as patient advocates. Students encountering physical restraints should ask questions based on values of patient-centeredness, autonomy, and advocacy. There is a need for education that facilitates reflection and questioning so that it informs students' ethical thinking which may enhance nurse advocacy to reduce restraint use. CONCLUSIONS: Restraints provide contexts in which students must face tensions between nursing values and clinical reality. Further research on nursing education strategies within non-psychiatric settings is needed to reduce physical restraints.

[Development and evaluation of complex interventions in nursing : Application of the medical research council's framework using the example of interventions to prevent physical restraints]. / Entwicklung und Evaluation komplexer Interventionen in der Pflege : Anwendung des Rahmenmodells des Medical Research Council am Beispiel von Interventionen zur Vermeidung freiheitsentziehender Maßnahmen.

Many nursing interventions are complex. They comprise different intervention elements (components) and aim to change processes or behaviours of individuals or groups. A framework of the British Medical Research Council comprises methodological recommendations for the development and evaluation of complex interventions. This narrative review describes the framework's methodological recommendations using an example of interventions to reduce physical restraints in hospital and long-term care settings, such as bedrails or belts in chairs and beds. In addition to the characteristics of the complex interventions, the development and theoretical foundation of the interventions as well as the feasibility test and evaluation is described.

Spit Hoods: Reforms to Law and Practice.

Spit hoods have been used for decades to reduce the ability of people to spit and bite police officers, corrective services officers, paramedics, doctors and nurses. However, historically and in public consciousness they have sinister resonances and often induce fear, panic and distress in persons to whom they are applied or in whose presence they are worn. Problematically frequently spit hoods have been used on detainees from ethnic minorities, including in Australia, on Indigenous persons, individuals with mental illnesses and children taken into custody. On a number of occasions spit hoods have been used with other forms of restraint and been associated with deaths in custody. This editorial reviews high profile cases internationally where spit hoods have played a role in precipitating deaths, important reports and reviews, including from coroners, ombudsmen and commissions of inquiry, into their abuse, and law reform in relation to spit hoods. It supports their abandonment and their replacement with other personal protective equipment options for maintaining custodians' and carers' occupational health and safety.

Reducing the Use of Mechanical Restraints in the Medical-Surgical Department.

BACKGROUND: The most crucial discussion in psychiatric hospitals is the safety of patients, especially during incidents that have the potential to cause physical harm such as those where mechanical restraints are used. AIM: The goal of the project was to reduce the use of mechanical restraints by 25% within 10 weeks in two piloted medical-surgical units. METHOD: A total of 60 articles were examined for relevance; out of these, the author used 30 studies that were based on observational, literature review, quantitative analysis, or clinical trial methodologies to conduct a comprehensive literature review. The author used a retrospective and descriptive design of chart review data collection to implement the project. The six core strategies framework, coupled with the creation of mental health championship role, was implemented to mitigate the problem. RESULTS: This study shows that the implementation of the six core strategies and the role of a mental health champion helped reduce the use of mechanical restraints by 100%. CONCLUSION: A total of 3,072 patients' charts were reviewed in which there were three PERT (Psychiatric Emergency Response Team) activation and no mechanical restraint events, which showed a considerable quality improvement compared to the pre-implementation data collection of 37 PERT and 14 mechanical restraint events. The implications for practice and further study in the field are the involvement of more authors with similar expertise, the use of a control group for comparison, and a longer length of study duration.

[Physical restraints in acute hospitals: A quantitative observational study as a starting point for the further development of quality management]. / Mechanische freiheitsentziehende Maßnahmen im Krankenhaus.

Physical restraints in acute hospitals: A quantitative observational study as a starting point for the further development of quality management Abstract: Background: Despite the known associated risks and adverse events, physical restraints are mostly observed in daily care practice of long-term care. Comparatively few studies are available for normal wards. Research question/aim: The explorative cross-sectional study investigated prevalences, types and reasons of physical restraints in nine selected normal wards of a maximum care hospital. Methods: The prevalences and types of physical restraints were collected in the early and late shift in summer 2020 via direct observation using standardised observation forms. The reasons for the use were recorded via a standardised survey of the nursing staff. Results: In the early shift, 15 out of 167 patients had physical restraints (9%), in the late shift 23 out of 191 (12%). People over 80 years were most affected (n = 8; 23.5% and n = 14, 25.9%). The highest prevalence was found in the clinic for neurogeriatrics with 21.4% (n = 3) and 37.5% (n = 6). Bedside restraints were used particularly frequently (n = 14; 93.3% and n = 22, 95.7%, resp.). The physical restraints were predominantly justified with the protection against fall injuries (n = 8, 53.3% and n = 15, 65.2%). Conclusions: Raising awareness among nursing staff through training and other accompanying measures are starting points for reducing physical restraints. In order to achieve sustainable changes, the management level should initiate appropriate measures and consistently accompany their implementation.
