Falls among Chinese stroke patients during rehabilitation

OBJECTIVE: To investigate the incidence, circumstances, and risk factors of falls among Chinese stroke patients during inpatient rehabilitation. DESIGN: Historical cohort study. SETTING: A 25-bed stroke rehabilitation unit in Hong Kong. PARTICIPANTS: Six hundred seventy-seven patients admitted consecutively to the unit approximately 1 week after acute stroke. INTERVENTIONS: All patients received conventional rehabilitation therapies, and a protocol to analyze the causes of falls and to advise on prevention was followed in the unit. MAIN OUTCOME MEASURES: A fall was defined as any unplanned "touch to the floor" of any part of a patient's body, excluding the feet. The fall rate and circumstances were studied. Demography, Abbreviated Mental Test score, Barthel Index score on admission, urinary incontinence, dysphasia, hemiplegia, hemiparesthesia, vision and hearing impairment, and the risk factors of stroke were analyzed by logistic regression for their relation to falls. RESULTS: Seventy-eight patients (11.5%) had falls. The fall rate was 5.5 per 1000 patient days. Eighty-five percent of the falls occurred in daytime and 71% at the bedside. Moderate to severe disability on the Barthal Index admission (6-14) and dysphasia were associated with an increased risk of falls (odds ratio [OR] = 2.64; 95% confidence interval [CI], 1.26-5.51; OR = 1.81; 95% CI, 1.03-3.17, respectively). CONCLUSIONS: Stroke patients in China had a significant fall rate during rehabilitation, but it was lower than rates reported in the Western stroke populations. The fall protocol followed in our unit might have reduced the incidence of repeated falls. The circumstances of falls were, however, similar. Moderate to severe disability on admission and dysphasia were 2 independent predictors for falls, and more intensive fall prevention efforts should focus on this group of patients.     

Implementation of a patient fall prevention program.

Falls among hospitalized patients are common occurrences and can have detrimental effects on patient outcomes. Identifying high-risk patients and taking measures to prevent patient falls have been successful. The purpose of this project was to decrease the fall rate in adult neuroscience patients. This was accomplished through implementation of a patient fall prevention program. Patients were assessed for risk factors associated with patient falls. Risk factors were identified through the use of the patient's history, nursing data base and patient classification system. Patients with identified risk factors were placed on fall precautions which included interventions specifically designed to prevent patient falls. This project resulted in a decrease in the number of patient falls and increased staff awareness of the risk factors associated with falls among adult neuroscience patients.     

A standardized assessment and intervention protocol for managing risk for falls on a geriatric rehabilitation unit.

This article describes the intervention protocols implemented at the Sisters of Charity Hospital of Ottawa, Canada on a 36-bed geriatric rehabilitation unit for managing the risk for falls in patients assessed to be at high, moderate, or low risk. The implementation of tailored protocols is of particular importance on rehabilitation units because staff must balance the treatment goal to increase patient mobility, activity level, and independence with the need to prevent falls. Thus, this article also describes the related standardized criteria and decisional guidelines used in determining patients' level of independence on the unit for each fall-risk category. This article concludes with an outline of practices designed to facilitate safe transfers and completion of activities of daily living among geriatric patients with functional impairments by teaching and promoting the use of behavioral compensatory strategies for disability-related deficits.     

An analysis of falls occurring in patients with stroke on an acute rehabilitation unit.

Falls are a common occurrence in stroke patients admitted to a rehabilitation unit. This study evaluates the effect of current fall risk screening and prevention strategies on the number of falls in stroke patients admitted to an acute rehabilitation facility. All stroke patients admitted to a designated acute rehabilitation unit were considered at risk for falls by virtue of their diagnosis. These patients were studied retrospectively during a 24-month period. Wheelchair lap belts and bedrails were provided to all patients admitted to the unit. Further measures consisting of bed and chair alarms, enclosed beds, and placement in rooms close to the nursing station were implemented with high-fall risk patients. One hundred seventeen (15.5%) of the 754 patients in this study fell. The fall index rate was 8.2 falls, based on patient care days during the study period. No injury was observed in 143 of 159 fall cases (90%). In 13 cases (8%) there were only minor injuries, and 3 falls (2%) resulted in serious injuries. Current preventive strategies decrease the number of falls and the severity of fall-related injuries. Patients who do fall are cognitively impaired on admission and have lower ambulation speed.     

Falls among dizzy patients in primary healthcare: an intervention study with control group

The objective of this study is to investigate whether vestibular rehabilitation can improve balance, reduce self-perceived handicap because of dizziness and, if possible, reduce falls among dizzy patients in primary healthcare. The study also finds out which of the balance measures and measure of self-perceived handicap, if any, predicted the risk of falls. The design of this study is an intervention study with control group. Fifty-eight patients, 65 years and older, with multisensory dizziness were taken as participants. The intervention group trained vestibular rehabilitation twice a week for 9 weeks. All patients were assessed at baseline and after 3 months, with four different balance measures and the Dizziness Handicap Inventory. After 6, 9 and 12 months, a follow-up by telephone was performed and, at 12 months, the patients also filled out a Dizziness Handicap Inventory questionnaire. Statistically significant differences were found between the groups between baseline and 3 months in one static balance measure and in one dynamic measure (P=0.038 and 0.044). In total, 40 falls were reported, 31 were classified as intrinsic falls, 26 of them caused by vertigo and nine falls were classified as extrinsic. No difference was found between the two groups in proportions of patients who fell. Poor ability to stand in tandem stance doubled the risk for falls. Vestibular rehabilitation can improve balance in elderly patients with multisensory dizziness. Vertigo is a common cause of falls in this group of patients and vestibular rehabilitation is a feasible treatment.     

Evaluation of the Morse Fall Scale: applicability in Chinese hospital populations

BACKGROUND: Patient falls have been identified as a significant health problem in the general hospital patient population. The Morse Fall Scale (MFS) is an individualized criterion-referenced assessment tool designed for measuring the likelihood of patient falls in hospitals. Despite the scale has demonstrated high validity and reliability in the previous researches, this study is to provide additional validity tests to determine the applicability in the Chinese hospital population. OBJECTIVES: To examine the predictive power of the MFS to predict patient falls. To conduct reliability tests on internal consistency, item analysis, inter-rater and test-retest reliability. DESIGN: The study was a cross-sectional study. SETTINGS: The medical and geriatric units of three rehabilitation hospitals in Hong Kong participated in the study. PARTICIPANTS: A convenience sample of 954 Chinese patients was recruited sequentially upon admission in the hospital ward units. They ranged in age from 17 to 100 years, with a mean of 70.2 years. METHODS: The patients were assessed for fall risk using the MFS on admission. Data was collected on the number of patients who fell rather than the number of falls. RESULTS: The scale had a sensitivity of 31% and a specificity of 83% when the cut-off point was determined at 45. The field test demonstrated excellent inter-rater reliability with an ICC value of 0.97 (95%CI 0.94-0.98). Repeatability was high with an ICC of 0.98 (95% CI 0.98-0.99). The evaluation revealed a low Cronbach's alpha coefficient and a low to moderate item-to-scale correlation. CONCLUSIONS: The evidence collected in this study has shown both the positive and negative aspects of using the MFS in assessing the fall risk of Chinese patients during rehabilitation. The discriminative validity and internal consistency reliability provide researchers and clinicians with a major step in further developing or modifying the scale.     

The incidence and consequences of falls in stroke patients during inpatient rehabilitation: factors associated with high risk

OBJECTIVES: To determine the incidence of falls on a stroke rehabilitation unit; to assess the frequency and nature of injuries; and to identify risk factors predictive of falls, functional outcomes, and impairments. DESIGN: Retrospective cohort study. SETTING: An inpatient stroke rehabilitation unit. PARTICIPANTS: Two hundred thirty-eight consecutive stroke patient admissions. INTERVENTIONS: Incident reports completed on patients who experienced a fall while on the unit were reviewed and resultant injuries categorized (abrasions, lacerations, fractures). MAIN OUTCOME MEASURES: Stroke impairments and admission functional assessments, FIM instrument, Berg Balance Scale (BBS), and Chedoke-McMaster (CM) Stroke Impairment Inventory of fallers were compared with nonfallers. RESULTS: Of the 238 patients, 88 (37%) experienced at least 1 fall, and almost half of these (45 patients [19%]) experienced at least 2 falls. A total of 180 falls were reported over the 5-year period. Of the 180 reported falls, 33% occurred when patients were using their wheelchairs. Injuries occurred in 22% of the reported falls. These consisted of contusions (49%) and abrasions (41%), primarily of the upper (30.8%) and lower (25.6%) extremities. Only 1 fracture was reported. Fallers tended to have lower admission BBS scores (50% of patients with a score <30 fell vs 18% with a score >30, P <.01) and a lower score on the admission arm, leg, and foot components of the CM (P <.05). Patients who fell were also more likely to be apraxic (P <.014) and suffer from cognitive deficits (P <.01). Repeat fallers had lower admission FIM scores (P <.01) when compared with nonfallers. CONCLUSION: Although patients undergoing stroke rehabilitation experienced a significant number of falls, the incidence of serious injury was small. Patients who experienced at least 1 fall had significantly lower BBS, FIM, and CM arm, leg, and foot scores compared with nonfallers. These data suggest that groups of stroke patients who are at risk for falls within the rehabilitation setting can be identified by using a variety of impairment and functional assessments. This information may be potentially useful for designing interventions directed at reducing fall frequency among stroke survivors.     

Incidence, circumstances and consequences of falls in patients undergoing rehabilitation after a first stroke]

OBJECTIVES: To describe the incidence, circumstances, and consequences of falls in patients admitted in a rehabilitation ward after a stroke. METHODS: Prospective monitoring of falls over four years in a neurological rehabilitation unit. Use of fall registry. Inclusion criteria: age < 75 years, admission < 45 days after stroke onset, single stroke of 1 cerebral hemisphere (nonlacunar) or of the brain stem. Only falls due to loss of balance were considered; falls caused by a seizure or syncope were not considered. RESULTS: Of 217 consecutive patients with the inclusion criteria, 34 had fallen at least once (15.7%) and 10 twice (4.1%). Fall incidence, defined as the number of falls per patient per day was 2.2 per thousand. Half of the patients fell the first three weeks after admission. Most falls involved getting to or from the wheelchair or the bed; 1 patient had recovered minimal postural abilities at the gym but was not independent. Traumatic lesions were noted in 13 patients: they were minor in nine and severe in four, including three fractures. CONCLUSION: Falls due to loss of balance are a major problem in patients undergoing rehabilitation after a stroke. Getting to and from wheelchairs in the bedroom and bathroom by patients who are not allowed to do so play a key role in many falls. Prevention programs should consider this information.     

Strategies to reduce risk of fall-related injuries in rehabilitation nursing.

Rehabilitation nurses are in a critical position to lead interdisciplinary team fall prevention management, including injury risk reduction. This article provides an update for rehabilitation nurses on evidence-based strategies to reduce patients'risk of fall-related injuries. This content builds on existing literature by focusing on knowledge to promote patient responses that reduce the risk of falls and ultimately fall-related injuries. Although rehabilitation nurses understand the complex nature of falls, addressing the intrinsic and extrinsic risk factors that increase the risk of fall-related injuries requires both individually based treatment programs and a system-wide commitment. A plethora of literature discusses fall risks and falls, but this article profiles the at-risk patient and describes current and emerging evidence-based interventions to protect patients from fall-related injuries by reducing risk factors. This discussion is limited to exercise, environmental redesign, osteoporosis prevention, and hip protectors.     

The relationship of falls to injury among hospital in-patients

The need to reduce falls is driven by the need to reduce injury. If patients at risk of injury can be distinguished from the patients at risk of falls, there is the potential for a more effective fall risk management policy by targeting injury prevention measures. We conducted a prospective observational study, with blinded endpoint evaluation of 825 consecutive patients admitted to geriatric rehabilitation wards. We identified 150 fallers (18.2%) contributing 243 falls. Fifty-six patients sustained an injury contributing 73 (30.0%) injurious falls. Only five (6.8%) falls resulted in injury of major severity. We identified no significant differences in demographics between injurious and non-injurious falls. A logistic regression analyses of the independent risk factors of suffering an injurious fall were a history of falls (p=0.036), confusion (p=0.001) and an unsafe gait (p=0.03). However, we identified no significant differences in clinical characteristics between patients suffering injurious and non-injurious falls. None of the characteristics studied can identify patients prone to injury after a fall. Injury is largely unpredictable, and more research is needed to determine how injury can be prevented in patients at risk of falls.     

Combining the AM-PAC “6-Clicks” and the Morse Fall Scale to Predict Individuals at Risk for Falls in an Inpatient Rehabilitation Hospital

ObjectiveTo determine the effect of adding the Activity Measure for Post-Acute Care (AM-PAC) Inpatient ‘6-Clicks’ Short Forms to the Morse Fall Scale (MFS) to assess fall risk. Falls that occur in a rehabilitation hospital result in increased morbidity and mortality, increased cost, and negatively affect reimbursement. Identifying individuals at high risk for falls would enable targeted fall prevention strategies and facilitate appropriate resource allocation to address this critical patient safety issue.DesignWe used a retrospective observational design and repeated k-fold cross-validation (10 repeats and 10 folds) of logistic regression models with falls regressed onto: MFS alone, AM-PAC basic mobility and applied cognitive scales alone, and MFS and AM-PAC combined.SettingInpatient rehabilitation hospital.ParticipantsAfter exclusions, 2007 patients from an inpatient setting (N=2007; 131 experienced a fall). Primary diagnoses included 602 individuals with stroke (30%), 502 with brain injury (25%), 321 with spinal cord injury (16%), and 582 with other diagnoses (29%).InterventionsNot applicable.Main Outcome MeasuresExperience of a fall during inpatient stay.ResultsThe MFS at admission was associated with falls (area under the curve [AUC], 0.64). Above and beyond the MFS, AM-PAC applied cognitive and basic mobility at admission were also significantly associated with falls (combined model AUC, 0.70). Although MFS and applied cognition showed linear associations, there was evidence for a nonlinear association with AM-PAC basic mobility.ConclusionsThe AM-PAC basic mobility and AM-PAC applied cognitive scales showed associations with falls above and beyond the MFS. More work is needed to validate model predictions in an independent sample with truly longitudinal data; prediction accuracy would also need to be substantially improved. However, the current data do suggest that the AM-PAC has the potential to reduce the burden of fall management by focusing resources on a smaller cohort of patients identified as having a high fall risk.     

A randomized controlled trial of rehabilitation at home after stroke in Southwest Stockholm: outcome at six months

A 6-month follow-up of a single-blind, randomized, controlled trial in Southwest Stockholm was performed in order to evaluate the effect of early supported discharge and continued rehabilitation at home after stroke. Eighty-three stroke patients with moderate neurological impairments, continent, independent in feeding, and mental function within normal limits one week after onset were included in the study. The patients were allocated 1:1 to early supported discharge and continued rehabilitation at home by a specialized team, versus routine rehabilitation. Patient outcomes measured were motor capacity, dysphasia, activities of daily living, social activities, perceived dysfunction, mortality and reported falls. Data on length of stay in hospital; initial and recurrent during 6 months were compared. The 6-month follow-up of 78 patients showed no statistically significant differences in patient outcome. The results of multivariate logistic regression analysis suggest a positive effect of home rehabilitation on activities of daily living. At 3-6 months the frequency of significant improvements was higher in the intervention group. Death or dependency in activities of daily living was 24% in the intervention group compared with 44% in the control group. The mean initial hospitalization was 29 days in routine rehabilitation group versus 14 days in the home rehabilitation group. We conclude that for moderately disabled stroke patients with mental function within normal limits, early supported discharge and continued rehabilitation at home had no less a beneficial effect on patient outcome than routine rehabilitation, reduced initial hospitalization significantly and had no adverse effects on mortality and number of falls.     

Patient falls: profile for prevention

Patient falls are common in the hospital or long-term care setting. In a large Southwestern teaching hospital, patient falls have been monitored on an ongoing basis. A multidisciplinary task force developed a method of identifying patient fall risk factors. A survey was used concurrently as falls were reported during the month of July. Forty-seven falls were reported. Of this sample, neurological patients accounted for 12 (25.5%) of the incidents. The neurological patient fall profile was identified as a high-risk profile, and interventions were taken to prevent falls in this group. A second data collection was conducted six months later with this population. While the number of patients on the neurological services remained constant, the incidence of falls decreased (25%). By using a comprehensive approach of data collection and assessment, education, and follow-up, the institution has decreased neurological patient falls.     

Fear of falling among stroke survivors after discharge from inpatient rehabilitation

The objectives of this study were to assess the incidence of falls and fall consequences among patients who were discharged from inpatient stroke rehabilitation and to investigate the proportion of those who experienced a fear of falling following a fall. This was a follow-up postal questionnaire study of patients who were admitted to the rehabilitation ward in a local hospital (Japan) for stroke rehabilitation. Seventy-three patients who met inclusion criteria were sent questionnaires and 49 (67%) responded to the questionnaire. Thirty-three patients had at least one fall after discharge from the hospital and of these, four patients experienced fractures resulting from their falls. Twenty-nine patients developed a fear of falling. As falls are common in stroke survivors, more attention should be paid to falls after stroke during inpatient rehabilitation to prevent physical and emotional consequences of falls.     

Clinical Nursing Judgment Related to Reducing the Incidence of Falls by Elderly Patients

The incidence of falls among elderly patients has been and continues to be a major challenge for nurses. Falls add physical injury and mental stress to patients' existing health problems, are a deterrent to rehabilitation, and increase healthcare costs. This study describes the variables that nurses identify as influencing their clinical decision making and the nursing behaviors associated with preventing patient falls. The study was grounded in the theory that discretionary nursing behaviors are related to nursing expertise, and the study was guided by the assumption that such behaviors are proactive and anticipatory. An analysis of interviews of registered nurses (n = 14) working on a geriatric rehabilitation unit in a medical center in Ohio focused on the zones of association and the contextual meanings of language used by the nurses when discussing patient falls. Four themes emerged: the reasons for patient falls, identifying patients who are likely to fall, preventing falls, and nurses' feelings when patients fall.     

Prospective study of fall risk assessment among institutionalized elderly in Japan

Abstract The purpose of the present study was to identify risk factors for falls among institutionalized elderly, using the standardized risk assessment tool developed by Izumi. We examined 746 patients from three types of facilities: rehabilitation wards in four general hospitals, three long-term care facilities, and three nursing homes, for up to three months. The incidence of falls within all facilities was 12.5%. Patterns of relative risks of falling differed among types of facilities. The highest relative risk of fall in long-term care facilities and nursing homes was nurses' prediction, followed by history of fall and altered mentation. In contrast, that in general hospitals was mobility. In long-term care facilities, history of falls (odds 3.68, 95CI: 1.47–9.23) and interaction (history of falls and assistance with toileting) (odds 3.13, 95CI: 1.48–6.64) showed significance on adjusted-odds ratios for fall. History of falls, altered mentation, and assistance with toileting may be used to screen patients at a high risk for fall at admission.     

Accidental falls in a rehabilitation setting

Accidental falls among patients at a rehabilitation center were studied to provide data for ongoing risk management. Three series of variables were analyzed from the epidemiologic perspective. Environmental variables most frequently associated with accidental falls were week of hospitalization, day of week, activity levels, and site and equipment. Host factors of age and sex were also considered. Age and diagnosis (CVAs) were critical variables in comparing patients who fell with those who did not. Definitive directions have now emerged for development of a targeted preventive program.     

Retrospective analysis of falls in an inpatient rehabilitation centre for rheumatic and orthopaedic diseases

AIM: To analyse the frequency and circumstances of falls in an inpatient rehabilitation centre. METHODS: In a survey all falls reported to the Austrian accident insurance carrier were analysed and external circumstances of falls were evaluated. The survey covers a period of 64 months (Jan 2000 to April 2005): 10 820 inpatients (234 502 patient days); mean age 52.8 years; 1,252 patients aged >/= 70 years; 47 % male, 53 % female. RESULTS: Of 223 accidents registered, 140 (62.8 %) were falls. Of these, 17 patients had to be referred to a surgical unit for further treatment. In total, 1.29 % of all patients fell during their stay (with report to the accident insurance carrier), 0.16 % suffered major injuries from falls (with referral to surgical unit). Females fell more frequently than males. 39 % of the falls were associated with physical therapy. Most falls occurred in daytime. The location in the centre or the day of week showed no major influence on the frequency of falls. Falls occurred slightly more often in the first part of the three-week inpatient stay. CONCLUSION: The high total number of falls shows that falls are important in an inpatient rehabilitation centre for rheumatic and orthopaedic diseases. The analysis did not reveal any special location inside the rehabilitation centre with an increased risk of falls calling for urgent interventions. The active and activating physical therapies do not seem to increase the number of falls significantly.
