Identification of Patients at Risk for Falls in an Inpatient Rehabilitation Program

Inverted U-shaped relationship between Barthel Index Score and falls in Chinese non-bedridden patients: a cross-sectional study

BACKGROUND

Performing activities of daily living comprise an important risk factor for falls among non-bedridden stroke inpatients in rehabilitation departments.

OBJECTIVES

To explore the correlation between Barthel Index score and the occurrence of falls in non-bedridden stroke rehabilitation inpatients.

METHODS

In this cross-sectional study, information of patients grouped as non-bedridden patients by the Longshi Scale was collected.

RESULTS

A total of 3097 patients were included in this study, with a fall incidence of 10.43%. After adjusting covariates, the total score of Barthel Index and falls in non-bedridden inpatients after stroke presented an inverted U-shaped curve relationship, in which inflection point was 60. The effect sizes on the left and right sides of infection point were 1.02 (95%CI 1.00-1.04) and 0.97 (95%CI 0.96-0.99), respectively.

CONCLUSIONS

Non-bedridden stroke patients with moderate activities of daily living (ADL) capacity may be at particularly increased risk of falls in rehabilitation departments.

'Patient unable to express why he was on the floor, he has aphasia.' A content thematic analysis of medical records and incident reports on the falls of hospital patients with communication disability following stroke

BACKGROUND

People with communication disability following stroke are at risk of falls during inpatient rehabilitation. However, they are often excluded from hospital falls research, and little is known about the circumstances or outcomes of their falls to inform risk management strategies.

AIMS

To examine hospital medical records and incident reports relating to falls of patients with communication disability following stroke for content codes, categories and themes relating to communication.

METHODS & PROCEDURES

This medical record chart review examined data on 72 patients and 265 falls. A content thematic analysis was used to identify how patient communication is characterized in relation to falls, and their prevention and management strategies.

OUTCOMES & RESULTS

The data reflected that staff viewed patients having difficulty following simple instructions as contributing to falls. Gaining the attention of staff and communicating basic needs were also considered to be contributing factors for falls. Patients were often described as experiencing a fall when taking a risk or attempting to address an unmet basic need. Furthermore, written notes for patients with more severe communication disability reflected that the patient's communication impairments prevented staff from establishing the circumstances of some falls and complicated the assessment for injury following a fall.

CONCLUSIONS & IMPLICATIONS

The medical records and incident reports of patients with communication disability following stroke reveal that hospital staff recognize the impact of communication disability as potential risk factors for falls for this group. It was difficult for staff to report the circumstances of the fall for patients with severe communication disability. Despite the recognition of communication as a potential contributing factor, few medical record entries documented strategies related to communication interventions to improve patients' ability to understand instructions, gain attention or communicate basic needs.

WHAT THIS PAPER ADDS

What is already known on the subject People with stroke are at a high risk of falls during their hospital admission. However, little is known about the circumstances of their falls and the influence of communication disability on these falls. What this paper adds to existing knowledge Patients with communication disability have unique factors that contribute to their falls in the hospital. Patients were described as experiencing a fall when taking a risk or attempting to address an unmet need, and these falls were often related to a patient's difficulties communicating their basic needs, gaining attention from staff, and following simple instructions. What are the potential or actual clinical implications of this work? Communication disability as a risk factor for a fall, and fall prevention strategies tailored to the communication disability, were typically identified and documented by physiotherapists, occupational therapists and nursing staff. The inclusion of speech pathologists in fall risk assessment, management, and prevention strategies may provide crucial information regarding the patient's communication disability that may enhance their fall prevention plan.

Predicting Falls in Rehabilitation: A Comparison of Three Instruments Including Hester Davis

PURPOSE

The aim of this study was to evaluate the ability of the Hester Davis Scale (HDS), Section GG, and facility fall risk assessment scores to predict patients who fall during inpatient rehabilitation.

DESIGN

This study is an observational quality improvement project.

METHODS

Nurses administered the HDS in parallel to the facility's current fall risk assessment and Section GG of the Centers for Medicare & Medicaid Services Inpatient Rehabilitation Facility Patient Assessment Instrument. Receiver operating characteristic curves were compared in 1,645 patients. Relationships of individual scale items to falls were also assessed.

RESULTS

The HDS (area under the curve [AUC] = .680, 95% CI [.626, .734]), facility fall risk assessment (AUC = .688, 95% CI [.637, .740]), and Section GG scores (AUC = .687, 95% CI [.638, .735]) adequately identified patients who fell. AUCs did not significantly differ between assessments. HDS scores of ≥13, facility scores of ≥14, and Section GG scores of ≤51 resulted in the highest sensitivity/specificity balance.

CONCLUSIONS

HDS, facility fall risk assessment, and Section GG scores adequately and similarly identified patients of mixed diagnoses at risk of falling in inpatient rehabilitation.

CLINICAL RELEVANCE TO THE PRACTICE OF REHABILITATION NURSING

Rehabilitation nurses have several options including the HDS and Section GG to identify patients at greatest risk of falling.

Optimizing falls risk prediction for inpatient stroke rehabilitation: A secondary data analysis

BACKGROUND

Identifying individuals at risk for falls during inpatient stroke rehabilitation can ensure timely implementation of falls prevention strategies to minimize the negative personal and health system consequences of falls.

OBJECTIVES

To compare sociodemographic and clinical characteristics of fallers and non-fallers; and evaluate the ability of the Berg Balance Scale (BBS) and Morse Falls Scale (MFS) to predict falls in an inpatient stroke rehabilitation setting.

METHODS

A longitudinal study involving a secondary analysis of health record data from 818 patients with stroke admitted to an urban, rehabilitation hospital was conducted. A fall was defined as having ≥1 fall during the hospital stay. Cut-points on the BBS and MFS, alone and in combination, that optimized sensitivity and specificity for predicting falls, were identified.

RESULTS

Low admission BBS score and admission to a low-intensity rehabilitation program were associated with falling (p < .05). Optimal cut-points were 29 for the BBS (sensitivity: 82.4%; specificity: 57.4%) and 30 for the MFS (sensitivity: 73.2%; specificity: 31.4%) when used alone. Cut-points of 45 (BBS) and 30 (MFS) in combination optimized sensitivity (74.1%) and specificity (42.7%).

CONCLUSIONS

A BBS cut-point of 29 alone appears superior to using the MFS alone or combined with the BBS to predict falls.

Risk Factors and Characteristics of Falls Among Hospitalized Stroke Patients

Falls and fall-related injuries during hospitalization may cause serious problems and consequences for patients, their quality of life as well as increased healthcare expenses. The aim of the paper were to assess fall risks and identify risk factors, related to falls among stroke patients. This was a retrospective cohort study that included 217 neurological patients with acute stroke who have experienced fall during hospitalization. Morse Fall Scale was used to estimate a likelihood of falling for hospitalized patients. In total, 1.4% patients with acute stroke experienced a fall during hospitalization. According to the fall risk assessment, 77% of the patients presented a high risk for falls. Women, older respondents and those who were hospitalized for period longer than 22 days and who had higher levels of care, had higher values of Morse score. The most common risk factors for falls are: the presence of other medical diagnosis, the use of disability aids while walking, the use of intravenous therapy, disorientation in time and space, and the largest contribution to Morse score comes from using disability aids while walking and transferring patients. Greater risk of falling was observed in older neurological patients with ischemic type of stroke and weakness on the left side of the body, patients with longer hospitalization period and those with higher level of care.

Evaluation of the predictive validity of the Hessisch Oldendorf Risk of Falling Scale (HOSS)

Objective:

This study aims to further validate the Hessisch Oldendorf Risk of Falling Scale (HOSS) for neurological rehabilitation patients.

Design:

The overall scale performance and fall rate was calculated in a retrospective data analysis.

Setting:

The study was performed in a subacute care facility during inpatient neurological rehabilitation.

Subjects:

The study population (n = 512) included neurological and neurosurgical patients with heterogeneous levels of disability.

Main measures:

The HOSS total score and the suspected risk of falling were compared with the number of falls. Characteristics of fallers and non-fallers were compared using non-parametric group comparisons. Overall scale performance was assessed by calculating the area under the receiver operating characteristic curve of the HOSS as well as by calculating the sensitivity and specificity.

Results:

A total of 82 (16%) patients experienced at least one fall. Fallers were characterized by an older age, a longer length of stay, a more severe impairment in the activities of daily living upon admission, a hemiparesis, an orientation disorder, a need of a walking aid device and an urinary incontinence. The number of falls was associated with the HOSS total score. Sixty-four fallers and two hundred seventy-four non-fallers were correctly categorized leading to a sensitivity of 78.0% and a specificity of 63.7%. The area under the receiver operating characteristic curve of the HOSS was 0.778 ± 0.25 (CI = 0.729–0.828, P < 0.001).

Conclusion:

The scale performance of the HOSS showed a good sensitivity and an adequate specificity to identify neurological patients who are at high risk of falling during inpatient rehabilitation.

Evaluation of the Feasibility of a Two-Week Course of Aquatic Therapy and Thalassotherapy in a Mild Post-Stroke Population

Strokes are a leading cause of disability in developed countries. Patients with disabilities need rehabilitation to improve their physical functioning, mental status, and quality of life. Currently, no high-quality evidence can be found attesting the benefits of any of the interventions that are nowadays used. Water-based exercise may improve the physical conditions and quality of life of people in the post-stroke phase. The objective of this study is to test whether aquatic therapy in an enriched environment at the seaside (a thalassotherapy center) could play a role in this condition. A quasi-experimental prospective study consisting of a specific program assessed 62 patients with a mild–moderate disability pre- and post-2 weeks of intensive treatment. They followed a thalassotherapy regimen including aquatic therapy in a sea water pool at 32–34 °C for 45 min daily five times a week. The outcomes measured were the Berg Balance scale, the Timed Up and Go test, the 10-meter walking test, the 6-min walking test, the Pain Visual Analogue Scale, the WHO Well-being index, EuroQoL VAS and EuroQoL 5D. We observed a significant improvement in all outcomes measured (p < 0.001, except mobility EuroQoL p < 0.05), except in the other four dimensions of the EuroQoL 5D and 10-metre walking test (NS). Conclusion: A two-week intensive course of aquatic therapy and thalassotherapy may be beneficial in the short term by reducing pain and improving the functional status and overall well-being of post-stroke patients.

An analysis of fall incidence rate and risk factors in an inpatient rehabilitation unit: A retrospective study

BACKGROUND

Accurate prediction of fall likelihood is advantageous for instituting fall prevention program in rehabilitation facilities.

OBJECTIVE

This study was designed to determine the clinical measures, which can predict the risk of fall events in a rehabilitation hospital.

METHODS

Medical records of 166 patients (114 males and 52 females) who were hospitalized in an adult inpatient unit of a rehabilitation hospital were retrospectively analyzed for this study. As predictor variables for assessing fall risk, demographic data and the following measurements were selectively collected from patient's medical records: Tinetti Performance-Oriented Mobility Assessment-Ambulation (POMA-G), Timed Up and Go test (TUG), 10 m walk test, 2 min walk test, Korean version Mini-Mental State Examination (K-MMSE), Korean version of the Modified Barthel Index (KMBI), Berg Balance Scale (BBS), Global Deterioration Scale (GDS), and Morse Fall Scale (Morse FS).

RESULTS

The Morse FS, TUG, and age were found to be risk factors for the classification of faller and non-faller groups.

CONCLUSION

This study suggests Morse FS, TUG, and age in the routine initial assessment upon admission in a rehabilitation setting, as key variables for screening the risk of fall. Additionally, the cutoff scores of Morse FS and TUG were observed to be more rigid than other clinical settings.

Using Functional Independence Measure Subscales to Predict Falls-Rapid Assessment

BACKGROUND

Falls remain a major issue in inpatient rehabilitation. Decreased scores on the Functional Independence Measure (FIM), given to every patient, have been shown to predict falls risk.

PURPOSE

The aim of the study was to extend previous research using FIM to predict falls by using only subscales assessed earliest during admissions to indicate high risk of falls.

DESIGN

Retrospective cohort study.

METHODS

Two consecutive samples of patients (n1 = 1,553, n2 = 12,301) admitted to a rehabilitation hospital over 9-month and 5-year periods, respectively, were used to evaluate the predictive utility of using only a small number of FIM subscales. Subscales were selected from those assessed earliest and were related to previously published research on falls risk factors. The metric was developed using a historical data set and was validated with a second, separate group of patients. Receiver operating characteristic curves were used to evaluate predictive utility.

FINDINGS

The combination of Toileting and Expression subscales yielded a comparable area under the curve to the full FIM, and both were greater than the existing method of falls risk assessment. Likelihood of falling was strongly linearly related to score on the Toileting/Expression metric.

CONCLUSIONS

The sum of two FIM subscales can be used to predict which patients may fall during their stay in a rehabilitation hospital.

CLINICAL RELEVANCE

The FIM scores are assessed early during a patient's stay, are required for all Medicare patients, and may be useful for simple, rapid, and accurate assignment of falls risk.

A systematic review of falls in hospital for patients with communication disability: Highlighting an invisible population

BACKGROUND

Patients with communication disability, associated with impairments of speech, language, or voice, have a three-fold increased risk of adverse events in hospital. However, little research yet examines the causal relationship between communication disability and risk for specific adverse events in hospital.

OBJECTIVE

To examine the impact of a patient's communication disability on their falls risk in hospital.

METHODS

This systematic review examined 61 studies on falls of adult hospital patients with communication disability, and patients at high risk of communication disability, to determine whether or not communication disability increased risk for falls, and the nature of and reasons for any increased risk.

RESULTS

In total, 46 of the included studies (75%) reported on participants with communication disability, and the remainder included patients with health conditions placing them at high risk for communication disability. Two thirds of the studies examining falls risk identified communication disability as contributing to falls. Commonly, patients with communication disability were actively excluded from participation; measures of communication or cognition were not reported; and reasons for any increased risk of falls were not discussed.

CONCLUSIONS

There is some evidence that communication disability is associated with increased risk of falls. However, the role of communication disability in falls is under-researched, and reasons for the increased risk remain unclear. Practical applications: Including patients with communication disability in falls research is necessary to determine reasons for their increased risk of adverse events in hospital. Their inclusion might be helped by the involvement of speech-language pathologists in falls research teams.

Feasibility and predictive performance of the Hendrich Fall Risk Model II in a rehabilitation department: a prospective study

BACKGROUND

Falls are a common adverse event in both elderly inpatients and patients admitted to rehabilitation units. The Hendrich Fall Risk Model II (HIIFRM) has been already tested in all hospital wards with high fall rates, with the exception of the rehabilitation setting. This study's aim is to address the feasibility and predictive performances of HIIFRM in a hospital rehabilitation department.

METHODS

A 6 months prospective study in a Italian rehabilitation department with patients from orthopaedic, pulmonary, and neurological rehabilitation wards. All admitted patients were enrolled and assessed within 24 h of admission by means of the HIIFRM. The occurrence of falls was checked and recorded daily. HIIFRM feasibility was assessed as the percentage of successful administrations at admission. HIIFRM predictive performance was determined in terms of area under the Receiver Operating Characteristic (ROC) curve (AUC), best cutoff, sensitivity, specificity, positive and negative predictive values, along with their asymptotic 95% confidence intervals (95% CI).

RESULTS

One hundred ninety-one patents were admitted. HIIFRM was feasible in 147 cases (77%), 11 of which suffered a fall (7.5%). Failures in administration were mainly due to bedridden patients (e.g. minimally conscious state, vegetative state). AUC was 0.779(0.685-0.873). The original HIIFRM cutoff of 5 led to a sensitivity of 100% with a mere specificity of 49%(40-57%), thus suggesting using higher cutoffs. Moreover, the median score for non-fallers at rehabilitation units was higher than that reported in literature for geriatric non fallers. The best trade-off between sensitivity and specificity was obtained by using a cutoff of 8. This lead to sensitivity = 73%(46-99%), specificity = 72%(65-80%), positive predictive value = 17% and negative predictive value = 97%. These results support the use of the HIIFRM as a predictive tool.

CONCLUSIONS

The HIIFRM showed satisfactory feasibility and predictive performances in rehabilitation wards. Based on both available literature and these results, the prediction of falls among all hospital wards, with high risk of falling, could be achieved by means of a unique tool and two different cutoffs: a standard cutoff of 5 in geriatric wards and an adjusted higher cutoff in rehabilitation units, with predictive performances similar to those of the best-preforming pathology specific tools for fall-risk assessment.

Comparison of fall prediction by the Hessisch Oldendorf Fall Risk Scale and the Fall Risk Scale by Huhn in neurological rehabilitation: an observational study

Objective:

To calculate scale performance of the newly developed Hessisch Oldendorf Fall Risk Scale (HOSS) for classifying fallers and non-fallers in comparison with the Risk of Falling Scale by Huhn (FSH), a frequently used assessment tool.

Design:

A prospective observational trail was conducted.

Setting:

The study was performed in a large specialized neurological rehabilitation facility.

Subjects:

The study population ( n = 690) included neurological and neurosurgery patients during neurological rehabilitation with varying levels of disability. Around the half of the study patients were independent and dependent in the activities of daily living (ADL), respectively.

Interventions:

Fall risk of each patient was assessed by HOSS and FSH within the first seven days after admission.

Main measures:

Event of fall during rehabilitation was compared with HOSS and FSH scores as well as the according fall risk. Scale performance including sensitivity and specificity was calculated for both scales.

Results:

A total of 107 (15.5%) patients experienced at least one fall. In general, fallers were characterized by an older age, a prolonged length of stay, and a lower Barthel Index (higher dependence in the ADL) on admission than non-fallers. The verification of fall prediction for both scales showed a sensitivity of 83% and a specificity of 64% for the HOSS scale, and a sensitivity of 98% with a specificity of 12% for the FSH scale, respectively.

Conclusion:

The HOSS shows an adequate sensitivity, a higher specificity and therefore a better scale performance than the FSH. Thus, the HOSS might be superior to existing assessments.

Risk assessment and incidence of falls in adult hospitalized patients

Objectives:

assess the risk of falls in adult hospitalized patients and verify the incidence of the event in this environment.

Method:

cohort study, with approval by the Research Ethics Committee, which monitored 831 patients hospitalized at a university hospital. The Morse Fall Scale (MFS) was used to assess the risk and patients with high risk (≥45 points) were considered exposed to falls.

Results:

the mean MFS score was 39.4 (±19.4) points. Between the first and the final assessment, the score increased by 4.6%. The first assessment score presented a strong and positive correlation with the final assessment score (r=0.810; p=0.000).

Conclusion:

the higher the risk score for falls when the patient is admitted, the higher the score at the end of the hospitalization period and vice-versa. The incidence rate corresponded to 1.68% with a higher percentage of patients classified at high risk of falls.

Predicting falls: considerations for screening tool selection vs. screening tool development

AIMS

This paper discusses considerations for falls risk screening tool selection vs. the need to develop new tools.

BACKGROUND

Inpatient falls are a complex patient safety issue that represent a significant burden for the healthcare system. In the inpatient context, falls risk screening tools are most often used for predicting falls, but in some populations assessment tools are more suited, however in others, a clinician's clinical judgment may be just as effective. Limited external validity is a central issue with falls risk screening tools when used in different populations than the original study. There is clinical need for guidance regarding screening tool selection vs. the need to development new tools and how to effect change in relation to the prediction of falls.

DESIGN

Discussion paper.

DATA SOURCES

This discussion paper is based on our own experiences and research and is supported by literature.

IMPLICATIONS FOR NURSING

This paper provides clinicians with a better understanding of considerations for falls risk screening tool selection vs. the need to develop new tools. In doing so, it provides clinicians guidance on how to critique the efficacy and utility of their falls risk screening tool. This paper equips clinicians for effecting change in relation to the prediction of falls.

CONCLUSION

Falls risk prediction is a particularly complex patient safety issue. Clinicians need to be aware of the limitations of their tool used to predict falls.

Falls and fallers in traumatic brain injury (TBI) rehabilitation settings: an integrative review

PURPOSE

To critically appraise the research literature on the nature of falls and fallers in traumatic brain injury (TBI) rehabilitation settings.

METHOD

An integrative review of the literature using thematic analysis was undertaken. Papers identified via a systematic search strategy were independently appraised by two reviewers. A data extraction instrument was developed to record results and to aid identification of themes in the literature. Critical Appraisal Skills Programme instruments were utilised to conduct a methodological critique of the papers included.

RESULTS

Thirteen studies were identified as having between 4% and 100% TBI patients in their study cohorts. From these papers, up to 71% of falls took place in a patient's bedroom occurring in peaks and troughs over a 24-h period. With some divergent results, nine themes were identified describing faller characteristics including: (1) functional mobility impairments; (2) dizziness; (3) bladder and bowel dysfunction; (4) certain medications and number of medications prescribed; (5) executive functioning; (6) patient age; (7) fear of falling; (8) coma length following TBI; and (9) Functional Independence Measure (FIM™) total score, subscale scores and particular individual items.

CONCLUSIONS

Being a multifactorial phenomenon, falls are a complex clinical issue. Despite the heterogeneity of diagnosis related groups (DRGs) in the included studies, TBI patients were identified as a high falls risk patient population in several studies. Implications for Rehabilitation Due to multisystem impairments, falls in the traumatic brain injury (TBI) rehabilitation context are a multifactorial and significant clinical issue. When interpreting and generalising results from research into falls, clinicians need to be mindful that falls and faller characteristics may be dependent on study setting and patient population. There is need for context specific research into faller characteristics following a TBI; particularly in relation to post-traumatic amnesia.
