Progress toward a restraint-free environment in a large academic nursing facility

Interventions for preventing and reducing the use of physical restraints for older people in all long-term care settings

BACKGROUND

Physical restraints (PR), such as bedrails and belts in chairs or beds, are commonly used for older people receiving long-term care, despite clear evidence for the lack of effectiveness and safety, and widespread recommendations that their use should be avoided. This systematic review of the efficacy and safety of interventions to prevent and reduce the use of physical restraints outside hospital settings, i.e. in care homes and the community, updates our previous review published in 2011.

OBJECTIVES

To evaluate the effects of interventions to prevent and reduce the use of physical restraints for older people who require long-term care (either at home or in residential care facilities) SEARCH METHODS: We searched ALOIS, the Cochrane Dementia and Cognitive Improvement Group's register, MEDLINE (Ovid Sp), Embase (Ovid SP), PsycINFO (Ovid SP), CINAHL (EBSCOhost), Web of Science Core Collection (ISI Web of Science), LILACS (BIREME), ClinicalTrials.gov and the World Health Organization's meta-register, the International Clinical Trials Registry Portal, on 3 August 2022.

SELECTION CRITERIA

We included randomised controlled trials (RCTs) and controlled clinical trials (CCTs) that investigated the effects of interventions intended to prevent or reduce the use of physical restraints in older people who require long-term care. Studies conducted in residential care institutions or in the community, including patients' homes, were eligible for inclusion. We assigned all included interventions to categories based on their mechanisms and components.

DATA COLLECTION AND ANALYSIS

Two review authors independently selected the publications for inclusion, extracted study data, and assessed the risk of bias of all included studies. Primary outcomes were the number or proportion of people with at least one physical restraint, and serious adverse events related to PR use, such as death or serious injuries. We performed meta-analyses if necessary data were available. If meta-analyses were not feasible, we reported results narratively. We used GRADE methods to describe the certainty of the evidence.

MAIN RESULTS

We identified six new studies and included 11 studies with 19,003 participants in this review update. All studies were conducted in long-term residential care facilities. Ten studies were RCTs and one study a CCT. All studies included people with dementia. The mean age of the participants was approximately 85 years. Four studies investigated organisational interventions aiming to implement a least-restraint policy; six studies investigated simple educational interventions; and one study tested an intervention that provided staff with information about residents' fall risk. The control groups received usual care only in most studies although, in two studies, additional information materials about physical restraint reduction were provided. We judged the risk of selection bias to be high or unclear in eight studies. Risk of reporting bias was high in one study and unclear in eight studies. The organisational interventions intended to promote a least-restraint policy included a variety of components, such as education of staff, training of 'champions' of low-restraint practice, and components which aimed to facilitate a change in institutional policies and culture of care. We found moderate-certainty evidence that organisational interventions aimed at implementation of a least-restraint policy probably lead to a reduction in the number of residents with at least one use of PR (RR 0.86, 95% CI 0.78 to 0.94; 3849 participants, 4 studies) and a large reduction in the number of residents with at least one use of a belt for restraint (RR 0.54, 95% CI 0.40 to 0.73; 2711 participants, 3 studies). No adverse events occurred in the one study which reported this outcome. There was evidence from one study that organisational interventions probably reduce the duration of physical restraint use. We found that the interventions may have little or no effect on the number of falls or fall-related injuries (low-certainty evidence) and probably have little or no effect on the number of prescribed psychotropic medications (moderate-certainty evidence). One study found that organisational interventions result in little or no difference in quality of life (high-certainty evidence) and another study found that they may make little or no difference to agitation (low-certainty evidence). The simple educational interventions were intended to increase knowledge and change staff attitudes towards PR. As well as providing education, some interventions included further components to support change, such as ward-based guidance. We found pronounced between-group baseline imbalances in PR prevalence in some of the studies, which might have occurred because of the small number of clusters in the intervention and control groups. One study did not assess bedrails, which is the most commonly used method of restraint in nursing homes. Regarding the number of residents with at least one restraint, the results were inconsistent. We found very-low certainty evidence and we are uncertain about the effects of simple educational interventions on the number of residents with PR. None of the studies assessed or reported any serious adverse events. We found moderate-certainty evidence that simple educational interventions probably result in little or no difference in restraint intensity and may have little or no effect on falls, fall-related injuries, or agitation (low-certainty evidence each). Based on very low-certainty evidence we are uncertain about the effects of simple educational interventions on the number of participants with a prescription of at least one psychotropic medication. One study investigated an intervention that provided information about residents' fall risk to the nursing staff. We found low-certainty evidence that providing information about residents' fall risk may result in little or no difference in the mean number of PR or the number of falls. The study did not assess overall adverse events.

AUTHORS' CONCLUSIONS

Organisational interventions aimed to implement a least-restraint policy probably reduce the number of residents with at least one PR and probably largely reduce the number of residents with at least one belt. We are uncertain whether simple educational interventions reduce the use of physical restraints, and interventions providing information about residents' fall risk may result in little to no difference in the use of physical restraints. These results apply to long-term care institutions; we found no studies from community settings.

Classification of Neuropsychiatric Symptoms Requiring Antipsychotic Treatment in Patients with Alzheimer's Disease: Analysis of the CATIE-AD Study

BACKGROUND

The Neuropsychiatric Inventory (NPI) comprises 12 items, which were conventionally determined by psychopathological symptoms of patients with dementia. The clinical rating scales with structured questionnaires have been useful to evaluate neuropsychiatric symptoms (NPSs) of patients with dementia over the past twenty year.

OBJECTIVE

The aim of this study was to classify the conventional NPSs in patients with Alzheimer's disease (AD) requiring antipsychotic treatment for their NPSs into distinct clusters to simplify assessment of these numerous symptoms.

METHODS

Twelve items scores (product of severity and frequency of each symptom) in the NPI taken from the baseline visit were classified into subgroups by principle component analysis using data from 421 outpatients with AD enrolled in the Clinical Antipsychotic Trials of Intervention Effectiveness-Alzheimer's Disease (CATIE-AD) Phase 1. Chi square tests were conducted to examine the co-occurrence of the subgroups.

RESULTS

We found four distinct clusters: aggressiveness (agitation and irritabilities), apathy and eating problems (apathy and appetite/eating disturbance), psychosis (delusions and hallucinations), and emotion and disinhibition (depression, euphoria, and disinhibition). Anxiety, aberrant motor behavior, and sleep disturbance were not included by these clusters. Apathy and eating problems, and emotion and disinhibition co-occurred (p = 0.002), whereas aggressiveness and psychosis occurred independent of the other clusters.

CONCLUSIONS

Four distinct category clusters were identified from NPSs in patients with AD requiring antipsychotic treatment. Future studies should investigate psychosocial backgrounds or risk factors of each distinct cluster, in addition to their longitudinal course over treatment intervention.

Outcomes of nighttime physical restraint removal for severely impaired nursing home residents

There is ample evidence that physical restraint reduction does not lead to increased falls or injuries. This study tests the effect of removing nighttime restraints by comparing two groups: Restrained in bed at pre- but not postintervention (n = 51), or restrained in bed at both pre- and post-intervention (n = 11). No differences in nighttime fall rates between the two groups were detected.

Nighttime physical restraint removal does not lead to increases in falls from bed in older nursing home residents. Although markedly reduced in nursing homes, restraint use remains a common practice among hospitalized older adults. We should continue to focus efforts on developing new, individualized approaches to reduce risk of falling from bed among frail elders.

Physical restraint use and older patients' length of hospital stay

In both acute care and residential care settings, physical restraints are frequently used in the management of patients, older people in particular. Recently, the negative outcomes of physical restraint use have often been reported, but very limited research effort has been made to examine whether such nursing practice have any adverse effects on patients' length of stay (LOS) in hospitals. The aim of this study was to examine the association between physical restraint use on older patients during hospitalization and their LOS. Medical records of 910 older patients aged 60 years and above admitted to one of the Hong Kong public hospitals in 2007 were randomly selected and recorded during July to September 2011. The recorded items included patients' general health status, physical and cognitive function, the use of physical restraints, and patients' LOS. Hierarchical regression analysis was conducted to analyze the data. The results indicated that older patients' general health status, physical, and cognitive function were important factors affecting their LOS. Independent of these factors, the physical restraint use was still significantly predictive of longer LOS, and these two blocks of variables together served as an effective model in predicting older patients' LOS in the hospital. Since physical restraint use has been found to be predictive of longer hospital stay, physical restraints should be used with more caution and the use of it should be reduced on older patients in the hospital caring setting. All relevant health care staff should be aware of the negative effects of physical restraint use and should reduce the use of it in hospital caring and nursing home settings.

Effect of physical restraint reduction on older patients' hospital length of stay

OBJECTIVES

Physical restraints are often used to prevent falls and to secure medical devices in older people in hospitals. Restraint reduction has been advocated on the grounds that physical restraints have negative psychological effects and are not effective in preventing falls. The potential effect of restraint reduction on length of hospital stay (LOS) has not been investigated. This study was undertaken to compare the average length of stay of older patients in a convalescent medical ward setting before and after a restraint reduction program.

DESIGN

This is a retrospective study.

SETTING

A convalescent hospital in Hong Kong.

PARTICIPANTS

This study included 2000 patient episodes.

MEASUREMENTS

The use of physical restraint, LOS, and clinical outcomes of randomly selected patient episodes in the year before and after the implementation of a restraint reduction program were compared. The clinical outcomes included Modified Functional Ambulatory Categories and modified Barthel index. Subgroup analysis was performed on those with confusion as defined by dementia diagnosis, low abbreviated mental test score, or abnormal mental domain of Norton Score.

RESULTS

A total of 958 and 988 patient episodes admitted to 10 medical wards in a convalescent hospital in 2007 and 2009 were examined. There were no significant differences in the baseline characteristics of patients in the 2 years. With the implementation of the restraint reduction scheme, the rate of physical restraint use declined significantly from 13.3% in 2007 to 4.1% in 2009 for all patients. The average LOS of patients was significantly lower in the year after the implementation of restraint reduction (19.5 ± 20.7 versus 16.8 ± 13.4 days in 2007 and 2009 respectively, P < .001). On subgroup analysis, the reduction in LOS was significant in the cognitively impaired patients (23.0 ± 26.5 to 17.8 ± 15.0 days in 2007 and 2009 respectively, P < .001), but not in the cognitively normal patients. There were no significant differences between the 2 years in the incidence of fall, mobility, and activities of daily living on discharge.

CONCLUSION

Physical restraint reduction was associated with significant reduction in average length of stay in convalescent medical wards, especially in the cognitively impaired patients.

Interventions for preventing and reducing the use of physical restraints in long-term geriatric care

BACKGROUND

Physical restraints (PR) are commonly used in geriatric long-term care. Restraint-free care should be the aim of high quality nursing care.

OBJECTIVES

To evaluate the effectiveness of interventions to prevent and reduce the use of physical restraints in older people who require long-term nursing care (either in community nursing care or in residential care facilities).

SEARCH STRATEGY

The Cochrane Dementia and Cognitive Improvement Group's Specialized Register, MEDLINE, EMBASE, CINAHL, PsycINFO, LILACS, a number of trial registers and grey literature sources were searched on 7 September 2009. The following search terms were used: "physical restraint*", bedrail*, bedchair*, "containment measure*, elderly, "old people", geriatric*, aged, "nursing home*", "care home*", "geriatric care", "residential facilit*".

SELECTION CRITERIA

Individual or cluster-randomised controlled trials comparing an intervention aimed at reducing the use of physical restraints with usual care in long-term geriatric care settings.

DATA COLLECTION AND ANALYSIS

Two reviewers independently assessed the retrieved articles for relevance and methodological quality and extracted data. Critical appraisal of studies addressed risk of bias through selection bias, performance bias, attrition bias, and detection bias, as well as critera related to cluster designa. We contacted study authors for additional information where necessary. PR were defined heterogeneously throughout the studies. Not all studies offered sufficient data for aggregated data meta-analysis, and therefore study results are presented in a narrative form.

MAIN RESULTS

Five cluster-randomised controlled studies met the inclusion criteria. All of them investigated educational approaches. Two studies offered consultation in addition and two other studies offered guidance for nursing staff in addition. Four studies examined nursing home residents and one study residents in group dwelling units. No studies in community settings were included. Three studies included only one or two nursing homes per study condition. Overall, methodological quality of studies was low.The studies revealed inconsistent results. One study in the nursing home setting documented an increase of PR use in both groups after eight months, while the other three studies found reduced use of PR in the intervention groups after seven and 12 months of follow up respectively. The single study examining residents in group dwelling units found no change in PR use in the intervention group after six months whereas PR use increased significantly in the control group.

AUTHORS' CONCLUSIONS

There is insufficient evidence supporting the effectiveness of educational interventions targeting nursing staff for preventing or reducing the use of physical restraints in geriatric long-term care.

Programme d'intervention visant à réduire l'utilisation des contentions physiques dans des unités de soins de longue durée — mise en oeuvre et effets sur le personnel soignant

This study aimed at (a) developing a restraint reduction program, (b) describing its implementation in long-term care units, and (c) examining its effects on care staff's perceptions of and knowledge about the use of restraints. The program was composed of three parts: consciousness-raising meetings, staff education, and clinical follow-up. The study was a randomized, controlled clinical trial with eight intervention care units (five nursing homes) and 11 controls (five additional nursing homes). Care staff was surveyed at two time intervals over a 7-month period (pre- and post-test intervention; intervention care units: N = 171 [T0] and N = 158 [T1]; controls: N = 181 [T0] and N = 166 [T1]). The implementation of the program was successful and results showed significant changes in care staff perceptions of and knowledge about the use of restraints.

A Longitudinal Evaluation of Restraint Reduction within a Multi-site, Multi-model Canadian Continuing Care Organization

Bien que la documentation américaine sur la réduction de l'usage des moyens de contention soit relativement importante, les travaux de recherche publiés sur cette même question sont moins nombreux sur les pensionnaires d'un établissement canadien de soins de longue durée. Les statistiques des plus importants établissements de ce type financés et exploités au Canada ont mis au jour des attitudes révélatrices envers les moyens mécaniques de contention. Durant les quatre années d'une étude comportant une campagne visant à réduire l'utilisation de moyens mécaniques de contention, la prévalence organisationnelle est passée de 24,68 % à 16,01 %. Il existait une variabilité substantielle en matière de contention parmi les 11 centres de l'organisation (échelle de 0 à 39,86 % des pensionnaires faisant l'objet de contention) et tous sauf un ont pu réduire la contention mécanique. Des facilitateurs particuliers à la réalisation et au maintien de la réduction de la contention sont indiqués, notamment les établissements de petite taille, la fourniture de soins spécialisés (par ex., maladie d'Alzheimer), et un «champion» résidant sur place. Des obstacles particuliers, comme la grande taille d'un établissement et un champion résidant à l'extérieur font aussi l'objet de discussion.

Beliefs and practices regarding Alzheimer's disease and related dementias among Filipino home care workers in Israel

BACKGROUND

In the past few decades, foreign home care to frail older adults has become a common alternative to family care in many developed countries. Whereas Alzheimer's disease and related dementias (ADRD) are common conditions in this population of frail older adults, little is known about the beliefs of foreign home care workers about ADRD or about their practices.

METHODS

A mixed-methods design was conducted in 2006-2007 in Israel. The study included a survey of beliefs about ADRD completed by 184 Filipino home care workers and qualitative interviews with 29 Filipino home care workers.

RESULTS

On seven of the 14 belief items, more than 30% of the workers were in discordance with scientific view about ADRD. Those workers who were not informed about the care recipient's medical conditions were more likely to report beliefs that were inconsistent with current scientific knowledge. In qualitative interviews, Filipino home care workers reported using intuitively behavioral techniques when caring for older adults with ADRD.

CONCLUSIONS

Despite the fact that some of the workers' beliefs are inconsistent with current scientific view, their actual intuitive practices are consistent with the scientific paradigm. Specific emphasis has to be placed on encouraging workers' intuitive approach to ADRD and providing workers with ample information about the medical conditions and needs of the care recipient.

Long term care staff beliefs about evidence based practices for the management of dementia and agitation

CONTEXT

Despite a growing literature on effective interventions for Alzheimer's disease (AD) and agitation, the management of these conditions in long term care (LTC) often is inadequate. The goals of the present study were: (a) to evaluate existing beliefs about evidence based practices (EBP) for the management of Alzheimer's disease and agitation among LTC staff; and (b) to evaluate the contribution of demographic and attitudinal variables to LTC staff beliefs about these EBP.

METHOD

A cross sectional study of 371 LTC staff members completed an EBP questionnaire, a short demographic questionnaire, and an attitudinal questionnaire about AD and agitation.

RESULTS

Paraprofessional caregivers, those of lower educational level, and ethnic minorities were more likely to be in disagreement with the EBP views examined in this study. Those in disagreement with the EBP views also reported a preference towards not working with residents with AD and agitation and a sense of helplessness associated with such work. Disagreement with EBP views was associated with both normalization and stigmatization of AD and agitation.

CONCLUSIONS

Paraprofessional caregivers, ethnic minorities, and people of lower educational level are most at need for educational activities about AD and neuropsychiatric symptoms. Educational efforts geared towards changing the belief system of LTC staff should target not only EBP but also information about AD and agitation as conditions that are deviant from the normal aging process, yet non-stigmatizing. It is expected that following EBP will empower staff and improve staff motivation to work with residents with AD and agitation.

Nurses using physical restraints: Are the accused also the victims? - A study using focus group interviews

Background

To date, the literature has provided an abundance of evidence on the adverse outcomes of restraint use on patients. Reportedly, nurses are often the personnel who initiate restraint use and attribute its use to ensuring the safety of the restrained and the others. A clinical trial using staff education and administrative input as the key components of a restraint reduction program was conducted in a rehabilitation setting to examine whether there were any significant differences in the prevalence of restraint use pre- and post-intervention. Subsequent to the implementation of the intervention program, focus group interviews were conducted to determine the perspective of the nursing staff on the use of restraints and their opinions of appropriate means to reduce their use.

Method

Registered nurses working in units involved in the study were invited to participate in focus group interviews on a voluntary basis. Twenty-two registered nurses (three males [13.6%] and nineteen females [86.4%]) attended the four sessions. All interviews were audio taped and transcribed verbatim. Other than the author, another member of the project team validated the findings from the data analysis.

Results

Four themes were identified. Participants experienced internal conflicts when applying physical restraints and were ambivalent about their use, but they would use restraints nonetheless, mainly to prevent falls and injuries to patients. They felt that nurse staffing was inadequate and that they were doing the best they could. They experienced pressure from the management level and would have liked better support. Communication among the various stakeholders was a problem. Each party may have a different notion about what constitutes a restraint and how it can be safely used, adding further weight to the burden shouldered by staff.

Conclusion

Studies about restraints and restraint use have mostly focused on nurses' inadequate and often inaccurate knowledge about the use of restraints and its associated adverse effects. These studies, however, fail to note that nurses can also be victims of the system. Restraint use is a complex issue that needs to be understood in relation to the dynamics within an environment.

Implementation and Evaluation of a Nursing Home Fall Management Program

OBJECTIVES

To evaluate the feasibility and effectiveness of a falls management program (FMP) for nursing homes (NHs).

DESIGN

A quality improvement project with data collection throughout FMP implementation.

SETTING

NHs in Georgia owned and operated by a single nonprofit organization.

PARTICIPANTS

All residents of participating NHs.

INTERVENTION

A convenience sample of 19 NHs implemented the FMP. The FMP is a multifaceted quality improvement and culture change intervention. Key components included organizational leadership buy-in and support, a designated facility-based falls coordinator and interdisciplinary team, intensive education and training, and ongoing consultation and oversight by advanced practice nurses with expertise in falls management.

MEASUREMENTS

Process-of-care documentation using a detailed 24-item audit tool and fall and physical restraint use rates derived from quality improvement software currently used in all Georgia NHs (MyInnerView).

RESULTS

Care process documentation related to the assessment and management of fall risk improved significantly during implementation of the FMP. Restraint use decreased substantially during the project period, from 7.9% to 4.4% in the intervention NHs (a relative reduction of 44%), and decreased in the nonintervention NHs from 7.0% to 4.9% (a relative reduction of 30%). Fall rates remained stable in the intervention NHs (17.3 falls/100 residents per month at start and 16.4 falls/100 residents per month at end), whereas fall rates increased 26% in the NHs not implementing the FMP (from 15.0 falls/100 residents/per month to 18.9 falls/100 residents per month).

CONCLUSION

Implementation was associated with significantly improved care process documentation and a stable fall rate during a period of substantial reduction in the use of physical restraints. In contrast, fall rates increased in NHs owned by the same organization that did not implement the FMP. The FMP may be a helpful tool for NHs to manage fall risk while attempting to reduce physical restraint use in response to the Centers for Medicare and Medicaid Services quality initiatives.

Development and Testing of Tools to Assess Physical Restraint Use

BACKGROUND

To implement best practice in restraint use, healthcare providers and decision makers require current, accurate, and easily accessible information about restraint practices in their setting. There is a need for a reliable and valid instrument that is feasible for use in these settings to rapidly assess physical restraint use.

METHOD

Two instruments to assess physical restraint use were developed and tested: an observation tool and a chart audit. The instruments were tested in complex continuing care units and rehabilitation units at two healthcare organizations. The restraint use observation tool was administered by trained observers in a series of five observations over a 2-week period. Chart audits were conducted for a sample of residents. Inter-rater agreement of the observation tool and chart audit was assessed. Point prevalence estimates were obtained for each site. The time required to use the observation tool and complete chart audits as well as the comparability of findings from the two data sources were described.

FINDINGS

Restraint use observations were completed for 289 patients and chart audits were completed for 207 patients. Prevalence and patterns of restraint use varied between sites and across time periods. Observations took an average of 2.6 (Site A) and 0.6 (Site B) minutes per patient. There was excellent inter-rater agreement for most items on the observation tool with the exception of whether or not the patient was able to release or loosen the restraint. There was significant concordance but as expected, not complete agreement between paired estimates of prevalence using the observational tool and the chart audit.

CONCLUSION

The observation and chart audit tools are feasible to use and reliably assess physical restraint use in healthcare organizations. The patient's physical capacity to move independently, the patient's waking status, and the restraint's restriction of mobility are items that should be added to the observation tool. The tools are complementary and should be used in tandem to capture the multifaceted complexity of restraint use in health service organizations.

Psychiatric inpatients' perceptions of positive and negative aspects of physical restraint

This qualitative study explored the experiences and feelings of psychiatric inpatients concerning their first encounter with physical restraint. Its purpose was to determine whether restraint has any other effects, other than the intended one of protection. Thirty psychiatric inpatients who had experienced physical restraint in two acute admission wards within the previous two days, were interviewed by the principal researcher. About two-thirds of the participants expressed positive feelings towards staff who had shown concern about their needs and had been willing to help. Positive therapeutic effects, other than physical protection, were largely related to the caring attitudes and behavior demonstrated by the staff. Negative effects were related to the inability of staff to satisfy patients' needs for: concern, empathy, active listening, and information about restraint during and after its use. The conclusion of the study was that physical restraint could be a therapeutic intervention when health professionals were able to provide psychological and informational support to patients throughout the procedure. A perceived unsatisfactory caring attitude and behavior by the restraint provider would cause negative feelings in the patient and would be more likely to result in the patient struggling physically with the restrainer. Additional physical and psychological harm would also be experienced by patients in these circumstances.

Physical restraint use among nursing home residents: A comparison of two data collection methods

Background

In view of the issues surrounding physical restraint use, it is important to have a method of measurement as valid and reliable as possible. We determined the sensitivity and specificity of physical restraint use a) reported by nursing staff and b) reviewed from medical and nursing records in nursing home settings, by comparing these methods with direct observation.

Methods

We sampled eight care units in skilled nursing homes, seven care units in nursing homes and one long-term care unit in a hospital, from eight facilities which included 28 nurses and 377 residents. Physical restraint use was assessed the day following three periods of direct observation by two different means: interview with one or several members of the regular nursing staff, and review of medical and nursing records. Sensitivity and specificity values were calculated according to 2-by-2 contingency tables. Differences between the methods were assessed using the phi coefficient. Other information collected included: demographic characteristics, disruptive behaviors, body alignment problems, cognitive and functional skills.

Results

Compared to direct observation (gold standard), reported restraint use by nursing staff yielded a sensitivity of 87.4% at a specificity of 93.7% (phi = 0.84). When data was reviewed from subjects' medical and nursing records, sensitivity was reduced to 74.8%, and specificity to 86.3% (phi = 0.54). Justifications for restraint use including risk for falls, agitation, body alignment problems and aggressiveness were associated with the use of physical restraints.

Conclusions

The interview of nursing staff and the review of medical and nursing records are both valid and reliable techniques for measuring physical restraint use among nursing home residents. Higher sensitivity and specificity values were achieved when nursing staff was interviewed as compared to reviewing medical records. This study suggests that the interview of nursing staff is a more reliable method of data collection.

Reducing restraint use in a public psychiatric inpatient service

The use of behavioral restraint in psychiatric inpatients can have physically and emotionally damaging effects. However, staff may view the use of restraint as a routine and acceptable means of maintaining safety. The goal of this project was to reduce the use of restraint in a public psychiatric inpatient service that serves an economically disadvantaged urban population. Six interventions that primarily involved changing staff behavior were made to reduce the use of restraint. These included better identification of restraint-prone patients, a stress/anger management group for patients, staff training on crisis intervention, development of a crisis response team, daily review of all restraints, and an incentive system for the staff. The rate of restraint use (number of restraints/1000 patient-days) during the 3 years before the interventions was compared with the rate during the 2 years after the interventions. There was a significant decrease in the rate of restraint use after the restraint reduction initiatives were implemented. The reduction was not accompanied by a sustained increase in incidents of assault, suicidal behavior, or self-injury.

Patient injury and physical restraint devices: a systematic review

OBJECTIVE

To investigate physical restraint-related injuries. Areas of interest were the prevalence of injury, types of injuries, risk of sustaining an injury and specific restraint devices associated with injury.

DEFINITIONS

Injury in the context of this review was considered to be either direct injury, such as lacerations and strangulation, or indirect injury considered to be an adverse outcome such as increased mortality rates or duration of hospitalization.

METHOD

A comprehensive search was undertaken that involved all major databases and the reference list of all relevant papers. To be included in the review studies had to involve people in acute or residential care settings and report data related to injury caused by restraint devices. A number of different types of research designs were included in the review. The findings of studies were pooled using odds ratio and narrative discussion.

RESULTS

The search identified 11 papers reporting the findings of 12 observational studies. These studies were supplemented with the findings of a number of other types of studies that reported restraint-related data. The review highlights the potential danger of using physical restraint in acute and residential health care facilities. Observational studies suggest that physical restraint may increase the risk of death, falls, serious injury and increased duration of hospitalization. However, there is little information to enable the magnitude of the problem to be determined.

DISCUSSIONS

Many of the findings highlight the urgent need for further investigation into the use of physical restraint in health care facilities. Further research should investigate the magnitude of the problem and specific restraint devices associated with injury. However, given the limited nature of the evidence, this association should be investigated further using rigorous research methods.

Elements of successful restraint and seclusion reduction programs and their application in a large, urban, state psychiatric hospital

In recent years, there has been a strong desire on the part of inpatient psychiatric programs to reduce the use of seclusion and mechanical restraint. There is a consensus among those who have published descriptions of successfully implemented restraint and seclusion reduction programs that the essential elements of such programs are high level administrative endorsement, participation by recipients of mental health services, culture change, training, data analysis, and individualized treatment. This article describes these elements and their application in a successful restraint reduction program at Creedmoor Psychiatric Center, a large, urban, state-operated psychiatric hospital that reduced its combined restraint and seclusion rate by 67% over a period of 2 years.

A review of physical restraint minimization in the acute and residential care settings

OBJECTIVES

The objective of this review was to investigate physical restraint minimization in acute and residential care settings. The first aim was to determine the effectiveness of attempts to minimize the use of physical restraint, and the second was to generate a description of the characteristics of restraint minimization programmes.

METHOD

A comprehensive search was undertaken involving all major databases and the reference lists of all relevant papers. To be included in the review studies had to be an evaluation of restraint minimization in an acute or residential care setting. As only a single randomized controlled trial (RCT) was identified, it was not possible statistically to pool the findings of different studies on the effectiveness of restraint minimization. To generate a description of the characteristics of restraint minimization programmes, the reported components of these programmes were identified and categorized.

RESULTS

A total of 16 studies evaluating restraint minimization were identified: three in acute care and 13 in residential care. Of these, only one was an RCT, with the most common approach being the before and after study design. Based on the findings of the single RCT, education supported by expert consultation effectively reduced the use of restraint in residential care. There has been little evaluation of restraint minimization in acute care settings. The common approach to restraint minimization has involved a programme of multiple activities, with restraint education being the characteristic common to most programmes.

DISCUSSION

Evidence suggests that physical restraint can be safely reduced in residential care settings through a combination of education and expert clinical consultation. There is little information on restraint minimization in acute care settings. The major finding of this review is the need for further investigation into all aspects of restraint minimization.

Restraint use, restraint orders, and the risk of falls in hospitalized patients

OBJECTIVES

To determine the relationship between physical restraints and falls in the acute hospital setting.

DESIGN

Matched case-control study.

SETTING

Inpatients at a 528-bed, urban, community based, acute care hospital.

PARTICIPANTS

Two hundred twenty-eight patients who fell during hospitalization and 228 controls matched to cases by nursing unit and length of stay.

MEASUREMENTS

Persons who fell were systematically evaluated at the time of fall by trained fall evaluators. For the cases, we sought to validate "orders for restraints" using "observed restraint use," defined as the use of restraints at the time of fall as determined through direct observation or interviews with nursing staff.

RESULTS

Patients with orders for restraints were more likely to fall than patients without orders for restraints (multivariate relative risk = 6.3, 95% confidence interval (CI) = 1.8-22.3). However, in the cases, there was poor correlation between "orders for restraints" and "observed restraint use" at the time of fall (kappa = 0.15, 95% CI-0.4-0.34).

CONCLUSION

Because orders for restraint use may not reflect actual restraint use at the time of a fall, observational studies relating use of restraints to the risk of falls should be interpreted with caution. Despite this caveat, we could find no evidence that restraints protect hospitalize patients from falling.

Randomized clinical trial of a quality improvement intervention in nursing homes

PURPOSE

The purpose of the study was to determine if simply providing nursing facilities with comparative quality performance information and education about quality improvement would improve clinical practices and subsequently improve resident outcomes, or if a stronger intervention, expert clinical consultation with nursing facility staff, is needed.

DESIGN AND METHODS

Nursing facilities (n = 113) were randomly assigned to one of three groups: workshop and feedback reports only, workshop and feedback reports with clinical consultation, and control. Minimum Data Set (MDS) Quality Indicator (QI) feedback reports were prepared and sent quarterly to each facility in intervention groups for a year. Clinical consultation by a gerontological clinical nurse specialist (GCNS) was offered to those in the second group.

RESULTS

With the exception of MDS QI 27 (little or no activity), no significant differences in resident assessment measures were detected between the groups of facilities. However, outcomes of residents in nursing homes that actually took advantage of the clinical consultation of the GCNS demonstrated trends in improvements in QIs measuring falls, behavioral symptoms, little or no activity, and pressure ulcers (overall and for low-risk residents).

IMPLICATIONS

Simply providing comparative performance feedback is not enough to improve resident outcomes. It appears that only those nursing homes that sought the additional intensive support of the GCNS were able to effect enough change in clinical practice to improve resident outcomes significantly.

Using restraint with nursing home residents: a qualitative study of nursing staff perceptions and decision-making

The study reported in this paper applied a qualitative and interpretative approach to nursing staff perceptions of the use of restraint with elderly nursing home residents, and into nurses' decision-making on restraint use. The data were collected using unstructured interviews with a purposive sample of 20 trained and untrained nursing staff from two Swiss nursing homes. Data analysis was based on Colaizzi's phenomenological method. Three main themes were extracted from the data: (1) understanding the term restraint, (2) situations in which the decision to apply restraint is considered justified and (3) situations in which nursing staff are uncertain about the use of restraint. The underlying bases with respect to decision-making were: understanding restraint, the rights and responsibilities of both residents and staff, and the duties of staff. Staff members were ambiguous in their understanding of restraint and they showed positive as well as confused attitudes towards its use. Their behaviour was defensive and protective rather than challenging. Further research is required on what is meant by safety in care of the elderly nursing today. In nursing practice, as far as issues of restraint are concerned, greater attention should be devoted to the relationship between elderly residents' self-determination and responsibility for their actions.

Use of Physical Restraints on Hospitalized Psychogeriatric Patients

1. When making decisions about the use of physical restraints, minimizing the physical risk of patients was determined to be the most important obligation. 2. Nurses' understanding and consideration of important factors that influence restraint use are essential to its reduction. 3. Nurses should be aware of their ethical responsibilities to older patients and their families. They must ensure the patient's right to be informed and respect their dignity.

Interventions to promote collaboration between nurses and doctors

BACKGROUND

Lack of nurse-doctor collaboration contributes to problems in quality and efficiency of patient care.

OBJECTIVES

To assess the effects of interventions designed to improve nurse-doctor collaboration.

SEARCH STRATEGY

We searched the Cochrane Effective Practice and Organisation of Care Group specialised register and database of studies awaiting assessment, the Cochrane Database of Systematic Reviews, the Cochrane Controlled Trials Register, the Database of Abstracts of Reviews of Effectiveness, MEDLINE, and reference lists of articles up to the end of October 1999.

SELECTION CRITERIA

Randomised trials, controlled before-and-after studies and interrupted time series of interventions to improve collaboration between nursing and medical professionals sharing patient care in primary or hospital care settings.

DATA COLLECTION AND ANALYSIS

One reviewer assessed the eligibility of potentially relevant studies, extracted data and assessed the quality of included studies; a second reviewer undertook duplicate assessments on the eligibility of some articles and data abstraction on all included studies.

MAIN RESULTS

Two trials involving 1945 people were included. One six month trial involving 1102 admissions evaluated daily, structured, team ward rounds, in which nurses, doctors and other professionals made care decisions jointly. There was shortened average length of hospital stay (LOS) from 6.06 to 5.46 days, and reduced hospital charges from US$ 8090 to 6681. There were no differences in mortality rates or the type of care to which patients were discharged. Another three month trial involving 843 admissions compared two female wards and evaluated a four times per week round. There were no significant differences between the intervention and control wards in total average length of stay for all patients (11.7 days in intervention ward versus 11.6 in the control ward). Excluding patients who died in hospital revealed shortened length of stay in the intervention ward (intervention ward 10.5 days, control ward 11.9). Mortality rates were not significantly different.

REVIEWER'S CONCLUSIONS

Increasing collaboration improved outcomes of importance to patients and to health care managers. These gains were moderate and affected health care processes rather than outcomes. Further research is needed to confirm these findings. The logistic challenge presented by the complexity of the interventions and the need for large sample sizes due to the likely modest impact and rarity of outcome events may best be met by multi-centre studies. Before launching such studies qualitative research is needed to identify barriers to collaboration. Interventions other than nurse-doctor ward rounds and team meetings should also be tested.

The use of physical restraints to psychogeriatric patients in Hong Kong

The use of physical restraint has been a controversial intervention in the nursing management of hospitalized elderly patients in many countries. This ethnographic study was conducted in one psychogeriatric ward in Hong Kong in order to explore what determines psychiatric nurses' decisions to use restraints on their elderly patients. By comparing the findings of three data sources, comprising semistructured interviews, observations, and clinical records, five main themes were identified with regard to the nurses decision of restraint use. They included the rationale of physical restraint, consideration of alternative measures, consideration of adverse consequences, ethical considerations, and policy and documentation of restraint use. The findings of this study demonstrate that nurses must question the established practice myths about restraint use being the best way to maintain patient safety. Most importantly, nurses need cognitive and ethical preparation to face different situations in which physical restraint may be used.

Restraint reduction: research utilization and case study with cognitive impairment

Although great strides have been made in restraint reduction, restraints still present a challenge for long-term care facilities. Restraint reduction is particularly difficult with cognitively impaired residents. This article presents the implementation of a research-based approach to restraint reduction and a case study with a cognitively impaired resident. Two year after implementing the research-based approach, the restraint rate had decreased 28%. The case study with the cognitively impaired resident revealed an increase in nurse contacts but a decrease in nurse time after restraint reduction. Concern for the cognitively impaired resident's safety remained an issue for the staff. Discussion includes weighing the risk/benefit ratio of restraint use and considering dignity and quality of life.

Staff training decreases use of seclusion and restraint in an acute psychiatric hospital

Rates of seclusion and restraint in an urban psychiatric hospital were compared during the 12-month periods before and after implementing the recommendations of a multidisciplinary quality improvement work-group convened to reduce the hospital's use of physical containment. Interventions included a mandatory staff training session on the management of assaultive behavior, weekly discussion items during team meetings for each local ward, and hospital-wide publicity charting the ongoing progress of the effort. Total annual rates of restraint dropped 13.8%. The average duration of restraint per admission decreased 54.6%. Staff injuries were reduced by 18.8% during the study period.

Reducing inappropriate restraint use in Colorado's long-term care facilities

BACKGROUND

Many physical and psychosocial complications arise from the use of physical restraints. Restraints in nursing homes have been estimated to cause approximately 1 in every 1,000 nursing home deaths. When restraints are removed, quality of life and functional status improve; there does not appear to be an increase in serious falls, and serious injuries may even decline.

METHODS

To assess the current status in Colorado nursing homes, in 1997 the Colorado Foundation for Medical Care mailed a questionnaire to 214 nursing homes to identify remaining barriers to restraint reduction. Results were used to plan interventions to further reduce inappropriate use that met most providers' needs. Given providers' need for greater family and public awareness of the risks associated with restraints, the project team developed educational tools for distribution to families and a media campaign for the public. In addition, an assessment tool and educational materials were created to facilitate appropriate use of devices and implementation of least-restrictive interventions. Data were collected before and after the intervention phase on remaining barriers, frequency of assessment, and perceived level of success of restraint reduction.

RESULTS

Most of the 175 (82%) of Colorado's 214 long-term care providers who received educational materials found them very useful and recommended expansion to other states. Facilities indicated a higher perceived level of success in reducing restraints, an increase in the frequency of assessments, and a decrease in barriers to restraint reduction. The public awareness campaign, performed in tandem with the state health department, reached more than a half-million people in Colorado, using the slogan, "Restraints Have Risks!"

Physical restraints in nursing homes: a review of the literature since the Nursing Home Reform Act of 1987

The use of physical restraints is one of the most negative features of nursing home care. Their use significantly affects the quality of life of residents. In an attempt to limit the use of restraints, the Nursing Home Reform Act (NHRA) of 1987 contained provisions regulating their use. In this article, the authors review the literature on the use and consequences of physical restraints in nursing homes since the passage of the NHRA. First, they describe the history behind the use of restraints and define what is considered to be a physical restraint. Second, they examine the four most common justifications for restraint use. Third, they describe the incidence and prevalence of restraint use. Fourth, they address demographic and clinical characteristics of residents that have been found to be associated with restraint use. Fifth, they examine negative outcomes of restraining residents. Finally, they describe alternatives to using restraints.

Developing rehabilitative behavioral interventions for long-term care: technology transfer, acceptance, and maintenance issues

Rehabilitative behavioral interventions that are documented in clinical trials to improve nursing home resident outcomes and are recommended by practice guidelines are often not adapted for daily use in nursing homes and other long-term care (LTC) facilities. Failure to evaluate issues other than clinical efficacy when developing interventions contributes to this gap between efficacy and effectiveness in practice. A potential solution is a research model that supplements traditional clinical intervention research with methodology designed specifically to evaluate the ability of LTC facilities to implement the interventions. This paper discusses several critical issues of intervention and implementation that should be addressed, including targeting interventions, advocacy, cost-effectiveness, training, and quality control. We also describe how clinical trials could be designed and staged to increase the probability that effective interventions will be implemented in the day-to-day care of frail older patients in LTC facilities.

Physical restraint use in critical care: legal issues

Landmark federal legislation and several other social and clinical forces have induced nursing homes to reduce their use of physical or mechanical restraints on their residents during the past decade. Attention is being paid to the overuse of restraining devices and methods in acute care hospitals, including critical care units, and the need to develop strategies for their reduction or elimination. One of the most serious barriers to accomplishing this objective is anxiety on the part of health professionals and administrators about potential legal liability for patient injury. This article discusses the potential legal implications of physical restraint reduction in hospitals, with special emphasis on the critical care context. It places risks in realistic perspective, ultimately arguing that developing suitable alternatives to restraint use in most cases best serves the legal--as well as the clinical, ethical, and financial--interests of all concerned parties.

Use of restraints in the elderly

Chronologic age older than 65 years is a predictor for restraint use in the acute care setting. The therapeutic effect of restraints has not been established. Geriatric patients in the hospital are more vulnerable to the risks associated with physical and chemical restraints. A framework is presented to guide the clinician in the decision making process on restraint use. Nursing homes have been successful in the implementation of restraint reduction programs, and these models might be reviewed for applicability to the acute care setting.
