Mechanical restraints, rehabilitation therapies, and staffing adequacy as risk factors for falls in an elderly hospitalized population

Physical Harm and Death in the Context of Coercive Measures in Psychiatric Patients: A Systematic Review

Background: For centuries coercive measures in psychiatry have been means of averting acute danger. It has been known for almost as long that these measures can lead to harm or even death to those affected. Over the past two decades the topic has increasingly been the subject of scientific discussion and research. While the legal and ethical preconditions for coercive measures in psychiatry as well as epidemiological studies on their incidence and patients' subjective experiences have increasingly come into focus, research on possible adverse events has lagged behind. To our knowledge there is no systematic review on the harmful or even fatal physical adverse effects of coercive interventions in psychiatry. Methods: We searched the databases PubMed and CINAHL for primary literature with a search string based on the PICO framework including key words describing different psychiatric diagnoses, coercive measures, and harms. Results: In total, 67 eligible studies (mainly case reports and case series) of very heterogeneous quality were included. Two RCTs were found reporting position-dependent cardiac deterioration, but were, however, carried out with healthy people and were characterized by a small number of cases. Death was the most frequently reported harm: cardiac arrest by chest compression in 14 studies, cardiac arrest by strangulation in 9, and pulmonary embolism in 8 studies. Further harms were, among others, venous thromboembolism and injuries. Injuries during physical restraint were reported in 0.8-4% of cases. For other kinds of coercive interventions, there are no sufficient data. Venous thromboembolism occurred in a considerable percentage of cases during mechanical restraint, also under prophylaxis. The most commonly reported coercive measure was restraint, distinguishing in mechanical restraint (43 studies), physical restraint (22 studies), bedrails (eight studies), vest restraint (7 studies), and chair restraint (6 studies). Forced medication was explicitly mentioned only in two, but seems to have occurred in nine studies. Six studies included seclusion. Conclusion: Coercive measures can lead to physical harm or even death. However, there is a significant lack of data on the incidence of such adverse events related to coercive interventions. Though reported anecdotally, physical adverse events during seclusion appear to be highly underresearched.

Effectiveness of bedrails in preventing falls among hospitalized older adults: a systematic review

BACKGROUND

Falls are a major problem today affecting adults of any age, but the elderly are a population that is more susceptible to falls. Falls are the leading cause of injury or death among older adults. Hospitalized older people are particularly vulnerable to falls. Falls cause direct injuries (minor injuries, severe wounds of the soft tissues and bone fractures) to patients and increased length of stay. The prevention of falls is commonly considered an indicator of the quality of care. Therefore, health institutions and professionals treat the identification and implementation of strategies to prevent or minimize their effects as a high priority. Fall prevention interventions involving physical restraints are still common and considered a primary preventative measure, despite controversy in their use. One of the most frequently used restraint interventions is bedrails. The question of the effectiveness of bedrails in preventing falls cuts across all societies and cultures and has with significant implications for the clinical practice of nurses.

OBJECTIVES

The objective of this review was to identify the effectiveness of the use of bedrails in preventing falls among hospitalized older adults when compared with no use of bedrails or any type of physical restraints.

INCLUSION CRITERIA TYPES OF PARTICIPANTS

The current review considered studies that included hospitalized adults (female and male), 65 years and over with any clinical condition in a non-intensive care unit (ICU).

TYPES OF INTERVENTION(S)

The current review considered studies that evaluated the use of bedrails as a restraint to prevent falls among older adults in non-ICUs compared to no use of bedrails or any type of physical restraints, for example, bedrails versus no bedrails, and bedrails versus no wrist or ankle ties.

TYPES OF STUDIES

The current review considered any randomized controlled trials (RCTs). In the absence of RCTs, other research designs such as non-RCTs, before and after studies, cohort studies, case-control studies, descriptive studies, case series/reports and expert-opinion were considered.

OUTCOMES

The current review considered studies that included primary outcomes (number of patients who fell or the number of falls per patient) and secondary outcomes (number of head trauma, bone fractures or soft tissue injuries).

SEARCH STRATEGY

The search strategy aimed to find both published and unpublished articles. A three-step search strategy was utilized in 13 databases. Articles published in Portuguese, English and Spanish beginning from 1980 were considered for inclusion.

METHODOLOGICAL QUALITY

Assessment of methodological quality was not conducted as no articles were identified that met the inclusion criteria.

DATA EXTRACTION AND DATA SYNTHESIS

Data extraction and synthesis was not performed, because no articles were included in this systematic review.

RESULTS

The search identified a total of 875 potentially relevant articles. Sixteen articles were identified through the reference lists of all identified articles. One hundred and thirteen full-text papers were assessed by two independent reviewers to determine eligibility. However, 11 articles were not found (despite all the efforts), and 102 articles did not meet the inclusion criteria.

CONCLUSION

There is no scientific evidence comparing the use of bedrails in preventing falls among hospitalized older adults to no use of bedrails or any type of physical restraints.

Additional exercise for older subacute hospital inpatients to prevent falls: benefits and barriers to implementation and evaluation

Objective: To evaluate the clinical effectiveness and implementation of a falls prevention exercise programme for preventing falls in the subacute hospital setting.

Design: Randomized controlled trial, subgroup analysis.

Participants: Patients of a metropolitan subacute/aged rehabilitation hospital who were recommended for a falls prevention exercise programme when enrolled in a larger randomized controlled trial of a falls prevention programme.

Methods: Participants in both the control and intervention groups who were recommended for the exercise programme intervention were followed for the duration of their hospital stay to determine if falls occurred. Participants had their balance, strength and mobility assessed upon referral for the exercise programme and then again prior to discharge. Participation rates in the exercise programme were also recorded.

Results: Intervention group participants in this subgroup analysis had a significantly lower incidence of falls than their control group counterparts (control: 16.0 falls/1000 participant-days, intervention: 8.2 falls/1000 participant-days, log-rank test: P = 0.007). However few differences in secondary balance, strength and mobility outcomes were evident.

Conclusion: This exercise programme provided in addition to usual care may assist in the prevention of falls in the subacute hospital setting.

Examination of ethical dilemmas experienced by adult intensive care unit nurses in physical restraint practices

Nurses are more likely to face the dilemma of whether to resort to physical restraints or not and have a hard time making that decision. This is a descriptive study. A total of 55 nurses participated in the research. For data collection, a question form developed by researchers to determine perceptions of ethical dilemmas by nurses in the application of physical restraint was used. A descriptive analysis was made by calculating the mean, standard deviation, and maximum and minimum values. The nurses expressed (36.4%) having difficulty in deciding to use physical restraint. Nurses reported that they experience ethical dilemmas mainly in relation to the ethic principles of nonmaleficence, beneficence, and convenience. We have concluded that majority of nurses working in critical care units apply physical restraint to patients, although they are facing ethical dilemmas concerning harm and benefit principles during the application.

Nurses' use of physical restraints in four Turkish hospitals

PURPOSE

(a) Determine the frequency and types of physical restraints used by nurses in intensive care units, emergency departments, and neurosurgery wards; (b) understand nurses' attitudes toward physical restraint; and (c) identify complications in physically restrained patients.

DESIGN AND METHODS

This descriptive, cross-sectional study was carried out on 254 nurses working in intensive care units, emergency departments, and neurosurgery wards in four Turkish hospitals where physical restraints were used. The whole population was studied without any sampling, and data were collected via semistructured interviews from July 20 to September 6, 2005.

FINDINGS

Nurses used either wrist, ankle, or whole body restraints at various levels. Those nurses who worked in surgical intensive care units and emergency departments and had in-service training used more physical restraint than did others. Only a third of nurses decided on physical restraint together with physicians and three-fourths tried alternative methods. Nurses reported edema and cyanosis on wrist and arm regions, pressure ulcers on various regions, and aspiration and breathing difficulties in relation to physical restraint. Moreover, they reported 9 deaths of patients in chest restraints. Reduction in the frequency of caregiving was related to complications.

CONCLUSIONS

Actions to reduce use of and complications from physical restraints should include attention to nurse staffing and education about use of restraints.

Physical Restraint Reduction in the Acute Rehabilitation Setting

A prospective, continuous quality improvement study was implemented at a hospital on two rehabilitation units: stroke and brain injury. The purpose of the study was to decrease restraint use by 25% and to maintain fall rates no greater than 10% over baseline. A multi-component restraint reduction program was implemented that focused on administrative support, education, consultation, and feedback. Monthly restraint rates and fall rates were monitored and compared to the previous year's rates. Both units reduced restraint use. Importantly, this reduction was accomplished at the same time as a decline in fall rates.

A follow-up study on fall and fracture incidence in long-term care including the role of formal caregiver time on fall incidence rates

OBJECTIVE

To examine the impact of a fall prevention programme over a 12 month follow-up period after the introduction of a RCT and to describe possible differences between incidence density rate of falls associated with caregiver time during weekends and ordinary working days.

DESIGN

Prospective observational study, duration 12 months.

SETTING

Six community nursing homes, Germany.

PARTICIPANTS

Long-stay residents (n=881); 771 resident years; median age 85.0 years (min 60; max 101); 79.1% female.

MEASUREMENTS

Incidence density rate of falls and fractures, staff time per resident.

RESULTS

The incidence density rate over all days was 1367/1000 resident years (RY) for falls [95% confidence interval 1041;1693]. The incidence density rate of hip fractures was 29/1000 RY [95% confidence interval 12;45] and 29/1000 RY [95% confidence interval 12;45] for non-hip fractures. The incidence density rate showed similar results comparing weekends/ public holidays vs normal working days; falls 1193 vs 1447/ 1000 RY; hip fractures 25 vs 30/ 1000 RY and other fractures 16 vs 34/1000 RY.

CONCLUSION

During the period, we observed a marked decline of the fracture rate compared with the controlled phase of the intervention trial. A lower number of nursing care hours on weekends was not associated with a higher incidence density rate for falls, fallers, or any type of fracture.

Fall Prevention in a Swiss Acute Care Hospital Setting: Reducing Multiple Falls

Preventing in-hospital falls is an important goal in avoiding poor patient outcomes. In this quasi-experimental study, the authors evaluated the effectiveness of a nurse-led fall prevention program in a 300-bed Swiss hospital. Four hundred and nine patients (internal medicine) were included: intervention group (n = 198), usual-care group (n = 211). The program consisted of training nurses in the use of the Morse Fall Scale, and the implementation of 15 selected preventive interventions. In the intervention group, the proportion of patients at risk for falls was higher (p = .048), and fewer patients with multiple falls were observed (p = .009). The intervention program showed an effect in preventing multiple falls, but not first falls. The prolonged mean time to a first fall in a subgroup of fallers in the intervention group may indicate an increased awareness of the nurses and the appropriateness of the interventions used.

The relationship between patient blood pathology values and patient falls in an acute-care setting: a retrospective analysis

Few studies have investigated the relationship between patient falls and patient blood pathology values, which can reveal objective information about the health and nutritional status of a patient. It could be that some abnormal values are associated with patients that fall. The objectives of the current study were to determine whether blood pathology values were different in patients who fell compared to patients who did not fall, and whether there was a difference in the type and number of currently documented risk factors for falls found for patients who fell compared to patients who did not fall. A retrospective audit of patient incident reports and medical records was conducted in an acute-care hospital for 220 patients who fell and who did not fall. Faller and non-faller patients were matched by casemix type and length of stay. Findings revealed a significant relationship between patients who fell and the variables of age, confusion status and alkaline phosphatase blood values.

Physical and chemical restraints in acute care: Their potential impact on the rehabilitation of older people

Agitation is a major problem for older people and is present in over half of the hospitalizations for people > 65 years of age. In a previous study by the authors, results indicated that nursing actions often did not meet best-practice standards in the care of older, agitated patients. This paper builds on these results by reviewing the literature pertaining to the use of restraints and contributes to the body of knowledge surrounding the impact of the acute-care experience on rehabilitation outcomes. Successful rehabilitation relies on the improvement of functional health outcomes and, for this to happen, physical and emotional well-being are important. The sequelae of restraint use in acute care have the potential to alter peoples' ability to participate fully in a rehabilitation programme, thereby placing their future placement at risk. This paper explores the outcomes of restraint use in the acute-care setting and presents the argument that their effects are likely to be detrimental to rehabilitation outcomes.

Minimizing the use of restrictive devices in dementia patients at risk for falling

The accumulating empirical evidence demonstrates that restrictive devices can be removed without negative consequences. Most importantly, use of nonrestrictive measures has been correlated with positive patient outcomes and represents care that is dignified and safe for confused elders. Most of these nonrestrictive approaches promote mobility and functional recovery; however, testing of individual interventions is needed to further the science. As the research regarding restrictive devices has been translated into professional guidelines and regulatory standards, the prevalence of usage has declined dramatically. New institutional models of care discouraging routine use of restrictive devices also will foster innovative solutions to clinical problems associated with dementia.

Nurse???Patient Ratios

OBJECTIVE

To determine whether the peer-reviewed literature supports specific, minimum nurse-patient ratios for acute care hospitals and whether nurse staffing is associated with patient, nurse employee, or hospital outcomes.

BACKGROUND

Hospital care may be compromised by forces that have increased patient acuity, reduced the ratio of caregivers to patients, and lowered the level of training of these caregivers.

METHODS

We systematically reviewed studies of the effects of nurse staffing on patient, nurse employee, and hospital outcomes published between 1980 and 2003 to determine whether they could guide the setting of minimum licensed nurse-patient ratios in acute care hospitals.

RESULTS

Of 2897 titles and abstracts of interest, 490 articles were retrieved, and 43 met the inclusion criteria. Although all adjusted for case mix and skill mix, only one recent study addressed minimum nurse staffing ratios. Patient outcomes were limited to in-hospital, adverse events. Evidence suggests that richer nurse staffing is associated with lower failure-to-rescue rates, lower inpatient mortality rates, and shorter hospital stays.

CONCLUSION

The literature offers no support for specific, minimum nurse-patient ratios for acute care hospitals, especially in the absence of adjustments for skill and patient mix, although total nursing hours and skill mix do appear to affect some important patient outcomes.

A look at the problem of falls among people with cancer

People with cancer often have multiple risk factors for falls. A major risk factor is aging; because people often are diagnosed with cancer at an older age or are living longer with cancer, many are at risk for falls. Additional risk factors include impaired physical function, sensory-neurologic deficits, use of multiple medications, and deconditioning, often caused by treatment-induced fatigue. Of all types of accidents, falls pose the most serious threat to the elderly. Fall injuries can have serious consequences related to reduced physical functioning and quality of life. A detailed understanding and awareness of the risk factors (both intrinsic and extrinsic) and problems associated with falls can assist oncology nurses to be vigilant in the identification of patients at high risk for falls. These patients may benefit from protocols used in other patient populations, new interventions, or the use of assistive devices.

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.

The use of physical restraints as a safety measure in the care of older people in four rehabilitation wards: findings from an exploratory study

We investigated the prevalence and type of physical restraint used with older persons on four rehabilitation wards in Northern Ireland. A longitudinal observational approach was used. One hundred and two patients were observed on four occasions over a three-day period. Most of the patients (68%) were subjected to some form of physical restraint, side-rails being the most commonly observed method. Those who were restrained were dependent on nursing care to meet their needs and received more drugs than those whose mobility was not restricted. No association was found between restraint use and nursing staffing levels, nor was there any association with the incidence of falls. Nurses rationalised their use of restraint as being linked to wandering and patient protection in cases of confusional type behaviours. An association was found between stroke and the maintenance of positional support through the use of restraints (side-rails and screw-on tabletops). Approximately, one-third of those restrained had this noted in their care plans, with concomitant evidence of patient/family involvement in the restraining decision.

The effect of physical restraints on fall rates in older adults who are institutionalized

Since the Omnibus Budget Reconciliation Act (OBRA) of 1987, there has been a significant reduction in the use of physical restraints to prevent falls in older adults who are institutionalized because of the developing awareness of the physical and psychological problems associated with them. The purpose of this ex post facto descriptive study was to determine if there is a difference in falls when physical restraints are allowed or prohibited in one older adult population. Data from incident reports from a purposive sample of 97 older adults in one long-term care facility were analyzed before and after the implementation of a restraint-free policy. The results indicated no significant difference in the number of falls before and after the policy change. However, there was a significantly lower number of falls with injuries and a significantly higher number of falls without injuries. These findings suggest older adults will continue to fall with or without the use of physical restraints because of changes associated with the aging process and risk factors. Removing physical barriers from older adults and allowing freedom of movement may decrease the severity of injury sustained in a fall.

Perceptions of older people who have experienced physical restraint

It is well documented that the use of physical restraints on older people has been linked to negative clinical outcomes. However, less is known about the personal perspective of those who have been restrained. This study examines the perceptions of older people who have experienced physical restraints in a rehabilitation ward. A purposive sample was used of 17 male and female patients who were restrained. The patients were interviewed using the Subjective Experience of Being Restrained instrument (Strumpf and Evans, 1988) which is a semi-structured interview schedule. The most commonly used restraint devices included side rails, screw-on tabletops and reclining chairs. The data were analysed using content analysis. The results indicate mixed feelings regarding physical restraints. Patients' impressions of physical restraints included indifference of the devices to their perceived safety value. Overall, a minority of patients (n = 4) had positive feelings about physical restraints as they provided a sense of security to them. However, the negative comments of the patients were more prevalent and their responses were categorized in terms of institutional control, ritualised care, entrapment and discomfort, and possible alternatives.

Relatives' perceptions of side rail use on the older person in hospital

With an increasing emphasis on improving standards in the care of older people, the use of physical restraints has received growing attention in the nursing literature. Physical restraint use has been likened to abuse as it impedes the movement of a person, encourages dependence on staff and denies autonomy. Side rails (cot sides, bed rails) can be considered as a physical restrain device. The therapeutic use of restraint has not previously been adequately explained. Furthermore, there is a dearth of literature examining the personal experience of physical restraint use. The Family Interview Guide (Strumpf and Evans, 1988) was used to explore perceptions of nine relatives whose family had side rails used during their care in an older person ward. The findings of the study suggest that while families place value on the perceived safety function of side rails, they nonetheless have worries about their use. These pertain to the risk of patient entrapment and possible injury. Patients' relatives associated side rails with ritualized practice in gerontology and make suggestions for the re-design of side rails. The study also highlights the potential for increased family participation in the decision to use side rails.
