A pilot study of falls risk and vestibular dysfunction in older fallers presenting to hospital emergency departments

PURPOSE: To compare falls risk in older fallers and non-fallers, with an emphasis on dizziness and signs of vestibular dysfunction. METHOD: The fallers had presented to the Emergency Department of the Royal Melbourne Hospital, Australia following a fall and were discharged directly home (n = 20) (75% female, mean age 78 years). The non-fallers were an age and gender matched group, who had not fallen in the past 12 months (n = 20). All clients received a home-based assessment, which involved a comprehensive assessment of falls risk. RESULTS: Over three-quarters of the fallers took four or more medications, had balance impairments, and used a gait aid in the community. The fallers had a significantly higher falls risk score (P < 0.001), demonstrated significantly poorer balance (P < 0.001) and walked significantly more slowly (P < 0.001) than the non-fallers. There was no significant difference between the groups in their reports of dizziness (P = 0.68), although static balance testing (CTSIB condition 5) suggested a greater degree of underlying vestibular dysfunction in the group of fallers (P < 0.001). CONCLUSION: Older people discharged home from the ED following a fall are at high risk of falling in the future and have a greater level of vestibular dysfunction based on simple clinical testing. Additional clinically applicable tests of vestibular function are required to further investigate the relationship between vestibular dysfunction and falling in older people.     

Fall events among people with stroke living in the community: circumstances of falls and characteristics of fallers

OBJECTIVES: To describe the frequency and circumstances of falls among a community sample of people with stroke and to compare characteristics of fallers and nonfallers. DESIGN: Cross-sectional, observational study. SETTING: Community. PARTICIPANTS: Forty-one community-dwelling people with stroke (26 men, 15 women; mean age, 69.7 +/- 11.6y), of which 23 had right-hemisphere infarction, 16 left-hemisphere infarction, and 2 had a brainstem lesion. Time since onset of stroke ranged from 3 to 288 months (mean, 50mo). INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Standardized tests were used to measure mobility, upper limb function, activities of daily living (ADL ability), and mood. Information about fall events was collected by using a questionnaire. RESULTS: Twenty-one participants (50%) were classed as fallers, of whom 10 had fallen repeatedly. No significant differences were found between fallers and nonfallers on any of the measures used. However, those who had 2 or more falls (n = 10) had significantly reduced arm function (P = .018) and ADL ability (P = .010), compared with those who had not fallen or experienced near falls (n = 5). Loss of balance, misjudgment, and foot dragging during walking, turning, and sit to stand were reported by fallers as the suspected causes and activities leading to falls. CONCLUSIONS: The high risk of falling among people with stroke was evident in this community-based sample. Repeat fallers had greater mobility deficits and significantly reduced arm function and ADL ability than those who did not report any instability.     

Prevalence of Cardioinhibitory Carotid Sinus Hypersensitivity in Patients 50 Years or over Presenting to the Accident and Emergency Department with "Unexplained" or "Recurrent" Falls

To study the prevalence of Cardioinhibitory Carotid Sinus Hypersensitivity (CICSH) in patients 50 years or over presenting to casualty with "unexplained" or "recurrent" falls. The prospective study was from October 1, 1995 to April 30, 1996 in the Inner City Accident and Emergency Departments, Newcastle Upon Tyne, U.K. Ten thousand four hundred forty-three patients 50 years and over presented, of which 4,051 (39%) were fallers. Fallers were excluded if they lived over 15 miles from the hospital (81), were registered blind (17), were unable to speak English (22), were unable to previously walk (27), if there was a history of only one accidental fall (1,659) or were cognitively impaired (776: Mini Mental State Examination < 24 [30]) or if there was a clear attributable medical diagnosis for the fall (871). Five hundred ninety-eight "unexplained" or "recurrent" fallers (defined as three or more falls in the previous 12 months) were assessed for carotid sinus massage (CSM). One hundred forty-five patients declined CSM (24%), 70 (12%) had relative contraindications to CSM and 13 already had pacemakers in situ (2%). Two hundred seventy-nine underwent CSM, of whom 65 had CICSH (23%), which might be amenable to treatment with pacemakers. The prevalence of CICSH (a potentially treatable condition) in "unexplained" or "recurrent" fallers who present to the accident and emergency department is 23%. A randomized control study to assess benefit from pacemaker intervention in these patients is underway.     

Postural Control Is Impaired in People with COPD: An Observational Study

Purpose: We investigated deficits in postural control and fall risk in people with chronic obstructive pulmonary disease (COPD).Method: Twenty people with moderate to severe COPD (mean age 72.3 years, standard deviation [SD] 6.7 years) with a mean forced expiratory volume in 1 second (FEV(1)) of 46.7% (SD 13%) and 20 people (mean age 68.2 years, SD 8.1) who served as a comparison group were tested for postural control using the Sensory Organization Test (SOT). A score of zero in any trial of the SOT was registered as a fall. On the basis of the SOT results, participants were categorized as frequent fallers (two or more falls) or as fallers (one fall). To explore the potential influence of muscle weakness on postural control, knee extensors concentric muscle torque was assessed with an isokinetic dynamometer. Physical activity level was assessed with the Physical Activity Scale for the Elderly.Results: People with COPD showed a 10.8% lower score on the SOT (p=0.016) and experienced more falls (40) than the comparison group (12). The proportion of frequent fallers and fallers during the SOT was greater (p=0.021) in the COPD group (four of 10) than in the comparison group (two of seven). People with COPD showed deficits in knee extensors muscle strength (p=0.01) and a modest trend toward reduced physical activity level. However, neither of these factors explained the deficits in postural control observed in the COPD group.Conclusions: People with COPD show deficits in postural control and increased risk of falls as measured by the SOT. The deficits in postural control appear to be independent of muscle weakness and level of physical activity. Postural control interventions and fall risk strategies in the pulmonary rehabilitation of COPD are recommended.     

Is fall self-efficacy an independent predictor of recurrent fall events in older adults? Evidence from a 1-year prospective study

Falls, which are prevalent among older adults, may not only cause severe physical injuries, but also lead to low fall self-efficacy (FSE). Low FSE is associated with restricted activity, which putatively increases risk of future falls. However, emerging studies have failed to confirm this association. Furthermore, the interplay between age, gender, and fall history with falls has not been adequately addressed in adults aged 70 years or older. The aims of this secondary analysis were to: (1) prospectively explore the association of FSE and fall events considering age, gender, and fall history, and (2) examine the characteristics of fall events and fall-related outcomes. Forty-seven community-dwelling adults over 70 years of age were followed for about 12 months. During the follow-up, 22 participants with low FSE experienced 119 fall events whereas 25 participants with high FSE reported 106 fall events. Among fallers, 72.3% (n = 34) experienced recurrent fall events. About 15.0% (n = 34) of 225 fall events resulted in injuries and 4.0% of injuries required medical care. FSE was a statistically significant predictor of future fall events (incident rate ratio = 0.96, p = .013) regardless of age, gender, and fall history. Participants with low FSE were more likely than those with high FSE to fall more frequently without noticeable prodromal symptoms and apparent reasons. These findings suggest that FSE is an important protective factor against future fall events. However, interpretation of these results requires caution given the small sample size and effect size.     

Calcaneal bone mineral density in older patients who have fallen

BACKGROUND: Annually, 35-40% of those aged >65 years fall; up to 5% of such falls result in fracture. Fracture is determined both by propensity to fall and by bone fragility. AIM: To determine osteoporosis prevalence and predictors in patients who have fallen. DESIGN: Observational cross-sectional study. METHODS: We measured calcaneal BMD in 408 consecutive patients aged >50 years attending after falling. Fall number, fracture history, weight, height, and risk factors for falls and osteoporosis were recorded. T scores (SD above or below the mean for young adults) were derived in both sexes, and Z scores (SD above or below age-related normal score) in females. RESULTS: In females (n = 300, 74%), mean (SD) T score was -1.1(1.6), and mean Z score was 0(1.4); 127 (42%) had osteoporosis (T score < - 1.6). ROC curves confirmed significant relationships between osteoporosis and age, weight and height (all p < 0.0001). Incorporating fracture history, our model (fracture aged >50 years, age >83 years, weight <57 kg, height <153 cm as dichotomous variables) predicted osteoporosis with 91% sensitivity, 34% specificity. Of 108 male fallers, 36 (33%) had osteoporosis. Age, height and weight all predicted osteoporosis (p < 0.02). The resulting model (fracture aged >50 years, age > or =80 years, weight < or =68 kg, height < or =167 cm as dichotomous variables) predicted osteoporosis with 92% sensitivity, 30% specificity. DISCUSSION: Osteoporosis prevalence is not increased in female fallers compared to age-related norms; empirical use of osteoporosis treatment solely on the basis of falls thus appears inappropriate. In both sexes, the factors predicting osteoporosis were age, height and weight. Where BMD is not practical, possible or economical, our model may be a sensitive means of predicting fallers with osteoporosis.     

Relationship between obesity and falls by middle-aged and older women

It has been suggested that obesity increases fall risk, based on diminished static balance and increased fall-related injury risk. However, these findings only indirectly relate obesity and falls. The purpose of this study was to use existing data to directly explore the relationship between obesity and falls by community-dwelling women aged 55 years and older. Eighty-six subjects (42 obese) reported falls occurring during the previous year (retrospective falls), and over the following year responded to biweekly communications inquiring whether they fell or stumbled (prospective falls/stumbles). Because trips represent the largest fall cause by community-dwelling adults, we also analyzed outcomes and recovery strategies of 25 women (13 obese) after laboratory-induced trips. Obese and healthy weight women retrospectively reported similar fall rates (40.9% vs 40.5%; P=.97). Similar percentages of healthy weight and obese women prospectively fell (64.7% vs 64.3%; P=.98) and stumbled (38.9% vs 14.3%; P=.24). After laboratory-induced trips, 46.2% of obese verse 25.0% of healthy weight women fell (P=.44). Unlike healthy weight fallers, most obese fallers failed to initiate or complete the recovery step before full-body harness support. Obesity does not appear to increase overall fall risk; although, fall rates after laboratory-induced trips were notably higher, potentially due to altered recovery responses. An incomplete recovery step could increase impact force with the ground, predisposing obese individuals to injury. The fact that there is concurrence between 4 independent outcomes strengthens the findings, suggesting that further, large-scale studies are warranted to inform future clinical practice regarding fall-risk assessment for obese older adults.     

An epidemiological study of falls on integrated general medical wards

Reducing falls in hospital requires an environmental as well as a patient-orientated approach. We studied patient and ward characteristics relating to falls in an acute setting. In a prospective open observational study, we examined fall characteristics in two nuclear designed wards (A and B) and a longitudinal ward (C). We recorded 63 falls among 1609 patients. Ward C had the most falls (31 vs 18/14; p = 0.01), fall positive days (29 vs 15/10; p = 0.002) and fallers (27 vs 13/12; p = 0.001; OR 2.54, CI--1.41-4.57). Ward C had a higher cumulative risk of falls (p = 0.006) and fall positive days (p = 0.003). Choice of ward was a significant independent risk factor for falls (p = 0.01) when controlled for age, sex, and diagnostic variation between the wards. Most falls were intrinsic (A 66.7%, B 64.2%, C 61.3%, p = 0.45). A significantly higher proportion of falls on ward C occurred by the bed (p = 0.04). Significant differences exist between the wards, and fall reduction programmes should identify and compensate for adverse ward-related factors to increase the effectiveness of patient-targeted fall risk assessments.     

Outcomes from the implementation of a facility-specific evidence-based falls prevention intervention program in residential aged care

For residents in long-term care facilities, falling is a major concern requiring preventive intervention. A prospective cohort study measured the impact of falls reduction following the implementation of evidence-based fall prevention interventions in 9 Australian residential care facilities. An external project team provided a comprehensive audit of current practice. Facilitated by an action research approach, interventions were individualized to be facility- and patient-specific and included the following: environmental modifications such as low beds and height-adjustable chairs, movement alarms, hazard removal, and hip protectors. Participants included 670 residents and 650 staff from 9 facilities across 3 states. A significant reduction of falls were observed per site in the proportion of fallers (P = .044) and single fallers (P = .04). However, overall the number of falls was confounded by multiple falls in residents. Reduction in fallers was sustained in the 6-month follow-up phase. Positive outcomes from interventions varied between facilities. Further research is necessary to target frequent fallers.     

Fear of falling in stroke patients: relationship with previous falls and functional characteristics

The objectives of this study were to determine the relationship between fear of falling and functional characteristics of patients after stroke as well as to determine what characterizes fallers who score high fall-related self-efficacy, and nonfallers who score low fall-related self-efficacy. Patients (n=140) treated in a stroke unit during a 12-month period were included. On follow-up, fallers were identified and patients answered the questions in the Falls Efficacy Scale, Swedish version (FES-S). Assessments of motor capacity, functional mobility and balance were also made. In univariate analysis, low fall-related self-efficacy was significantly associated with increased age, female sex, earlier falls, visual and cognitive impairment, low mood and impaired physical function. In multivariate analysis, only earlier falls and physical function remained significant. Twenty percent of the patients scored low fall-related self-efficacy without having experienced a fall, and 11% who experienced a fall scored high fall-related self-efficacy. Impaired physical function was significantly associated with scoring low fall-related self-efficacy, for both fallers and nonfallers. Fear of falling is significantly associated with poor physical function and earlier falls. Falls Efficacy Scale, Swedish version could add useful information to a fall risk analysis. Patients scoring low fall-related self-efficacy should be offered fall prevention measures whether they have fallen or not.     

Predisposing factors for occasional and multiple falls in older Australians who live at home

This study, which was part of a larger study on the Health Status of Older People conducted in Melbourne, Australia, aimed to identify factors that discriminate between multiple and occasional falls amongst older people living at home. It used a survey of 1000 Australians aged 65 years and over. Subjects were classified as multiple fallers (two or more falls in the past year), occasional fallers (one fall in the past year), or non-fallers. Twenty-nine percent of older people who lived at home reported falling once or more in the previous 12 months. Nearly 20% of older people fell once in the previous 12 months and just under 10% fell more than once. Occasional fallers were more likely to be women (OR 1.75, 95% CI 1.26 to 2.45), to have reported back pain (OR 1.54, 95% CI 1.10 to 2.16) and were nearly twice as likely to have more than three medical conditions compared to non-fallers (OR 1.88, 95% CI 1.22 to 2.90). Multiple fallers were also more likely to be women (OR 1.61, 95% CI 1.03 to 2.51). More multiple fallers (17%) than occasional fallers (9%) reported being very afraid of falling. Intervention strategies should take into account these differing predisposing factors for multiple and occasional falls.     

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.     

Atrial fibrillation: an independent risk factor for nonaccidental falls in older patients

Background: Nonaccidental falls are often the result of a combination of factors including cardiovascular disorders such as orthostatic hypotension and unspecified cardiac arrhythmias. The objective of this study was to determine if there is an association between atrial fibrillation (AF) and nonaccidental falls. Methods: We reviewed the records of 442 consecutive patients >65 years old who presented to the Emergency Department at the University of Utah Medical Center with a complaint of fall. Results: Two-hundred eleven patients presented with nonaccidental fall, 231 patients with accidental fall. Patients with nonaccidental fall were more likely to be older, have a history of hypertension and neurological disorders, and taking five or more medications when compared to patients with accidental fall. Despite a similar prevalence of sinus rhythm at presentation, the prevalence of a history of AF was significantly higher in patients with nonaccidental fall compared to patients with accidental fall (26% vs 15%; P = 0.003). After adjusting for clinically and statistically significant predictors with a multivariate logistic regression analysis, AF, neurological disorders, and age ≤81 years were independent predictors of nonaccidental fall. In patients ≤81 years old (median age), the risk of nonaccidental falls was 2.5 times greater in patients with a history of AF when compared to those without a history of AF (odds ratio = 2.53 [confidence interval 95% 1.3-5], P = 0.007). Conclusion: AF is an independent risk factor for nonaccidental falls. Our results emphasize the need to screen for AF in patients presenting with nonaccidental fall. (PACE 2012; 35:973-979).     

Level of Mobility Limitations and Falls Status in Persons With Multiple Sclerosis

Objective

To investigate whether fall rates are constant across levels of mobility limitations.

Design

Secondary analysis of baseline assessments from a stratified randomized controlled trial.

Setting

Community.

Participants

Persons with multiple sclerosis (N=365) were divided into 5 groups based on the mobility section of the Guy's Neurological Disability Scale (GNDS): no walking impairment (n=82); impaired walking, no aid (n=87); unilateral support (n=76); bilateral support to walk (n=78); or occasional wheelchair user (n=42).

Interventions

Not applicable.

Main Outcome Measures

Self-reported fall history (ie, retrospective) in the preceding 3 months.

Results

One hundred twenty-four persons in the overall sample reported falling in the last 3 months (fall prevalence, 33.97%). Of the total sample, 17.8% reported 2 or more falls in the last 3 months. Chi-square analysis revealed a significant difference in the proportion of fallers across GNDS categories (χ²=42.64, P<.001). Post hoc analysis revealed that the group who walked with bilateral support had the greatest proportion of fallers (52.6%), while the group without walking impairment had the lowest proportion (15.9%). An examination of recurrent fallers as a function of group found that there were more recurrent fallers (70%) in the group that had a walking impairment but used no aid, relative to the other groups.

Conclusions

The current findings highlight that fall rates including recurrent fall prevalence are not uniform across mobility aid categories in persons with MS. Those using bilateral assistance for gait have the highest prevalence of fallers, and those with walking limitations and not yet using an aid had the greatest prevalence of multiple falls.     

Incidence and related clinical factors of falls among older Chinese veterans in military communities: a prospective study

[Purpose] The aim of this study was to determine fall incidence and explore clinical factors of falls among older Chinese veterans in military communities. [Subjects and Methods] We carried out a 12-month prospective study among 13 military communities in Beijing, China. Fall events were obtained by self-report to military community liaisons and monthly telephone interviews by researchers. [Results] Among the final sample of 447 older veterans, 86 fell once, 25 fell twice or more, and 152 falls occurred altogether. The incidence of falls and fallers were 342/1,000 person-years and 249/1,000 person-years. In Cox regression models, independent clinical factors associated with falls were visual acuity (RR=0.47), stroke (RR=2.43), lumbar diseases (RR=1.73), sedatives (RR=1.80), fall history in the past 6 months (RR=2.77), multiple chronic diseases (RR=1.53), multiple medications (RR=1.34), and five-repetition sit-to-stand test score (RR=1.41). Hearing acuity was close to being statistically significant. [Conclusion] The incidences of falls and fallers among older Chinese veterans were lower than those of Hong Kong and western countries. The clinical risk factors of falls were poor senses, stroke, lumbar diseases, taking sedatives, fall history in the past 6 months, having multiple chronic diseases, taking multiple medications, and poor physical function. The preventive strategies targeting the above risk factors are very significant for reducing falls.Key words: Falls, Incidence, Clinical factors     

Influence of sensory inputs on standing balance in community-dwelling elders with a recent history of falling.

Vision and/or ankle somatosensory inputs often do not correlate with the position of the center of gravity. In this case, visual or somatosensory information may be in conflict with other sensory systems that convey a true sense of body orientation. The purpose of this study was to determine how conflicting visual and ankle somatosensory inputs influenced standing balance in elders with a history of falls. Forty-seven community-dwelling elders (8 male, 39 female), between 65 and 96 years of age (mean = 80.5, SD = 9.0), participated in this project. Subjects with two or more falls in the 6 months prior to study were assigned to a fall group (n = 16), whereas those with no history of falling during the same time interval were assigned to a no-fall group (n = 31). In order to remove any bias in the testing procedure, the tester was not aware of group assignments. Subjects were evaluated using a sensory organization test (SOT) for standing balance and a "Get Up and Go" test (GUGT) for general mobility. Analysis of covariance was used to evaluate the SOT scores (by group, vision, and surface condition) and the GUGT scores. Body sway is known to increase with the normal aging process, and for this reason, age was selected as a covariate. The association between the SOT total score and the GUGT score was evaluated using Spearman rank-order correlation coefficients. The results showed a significant interaction between group and surface conditions, which indicated a decreased stance duration for fallers on a compliant surface compared with the stance duration for nonfallers (adjusted mean faller stance duration = 53 seconds, SD = 42; mean nonfaller stance duration = 67 seconds, SD = 32). Subjects in the fall group also had significantly higher GUGT scores (which indicated poor mobility function) than did subjects in the nonfall group (adjusted mean faller GUGT score = 2.65, SD = 1.48; mean nonfaller GUGT score = 1.47, SD = 0.77). The Spearman correlation between total SOT scores and the GUGT scores was greater for fallers (r = -.67) than for nonfallers (r = -.44). Orientation input from the ankle appears to have greater importance for preventing falls compared with a visual reference. The SOT and GUGT may be useful in the field to establish criteria for screening elders in a fall-prevention program.     

Outcomes of a consult fall prevention screening clinic

OBJECTIVE: To report patient satisfaction and quality outcomes from a standardized, multicenter fall prevention screening clinic. DESIGN: Referrals were made to the fall prevention screening clinic, which was staffed by a physician, pharmacist, therapist, nurse, and the site coordinator. The fall prevention screening clinic staff utilized a team-meeting format with clearly delineated management options to determine the appropriate interventions based on various screening examinations. RESULTS: Primary care providers acknowledged pharmacy recommendations and >80% of the recommendations were followed. There was a reduction in reported falls (initial visit = 297 falls, follow-up visit = 141 falls, P = 0.0002) and in the number of recurrent fallers. There was a small (average difference = 1.8 secs) but significant (P = 0.025) decrease in the 8-foot Up-and-Go time, representing a functional improvement in walking speed. There was no significant change in the Fall Efficacy Scale, however. At least 80% of the patients reported that they were completely satisfied with their care. CONCLUSIONS: Patients who attended the fall prevention screening clinic demonstrated improved confidence during activities of daily living and reduced falls. They reported high satisfaction with the clinic format.     

Carotid Sinus Hypersensitivity is Common in Patients Presenting with Hip Fracture and Unexplained Falls

Background: We tried to determine the prevalence of carotid sinus hypersensitivity (CSH) in patients with hip fractures with and without a clear history of an accidental fall.
Methods: We studied 51 patients hospitalized for a hip fracture and 51 matched controls from our outpatients department. All patients were subjected to a carotid sinus massage in the supine and upright position . Patients were categorized in accidental (Group A) and unexplained (Group B) fallers.
Results: Six of 33 (18.2%) patients in Group A and 12 of 18 (66.7%) patients in Group B ( P < 0.001) had a positive response to the carotid sinus massage. Nine controls (17.6%) also demonstrated CSH. Patients in Group B were older (A: 75.5 ± 8.5 years vs B: 80.1 ± 5.9 years, P = 0.029) and were more likely to have a history of unexplained falls or syncope in the past (A: 0% vs B: 66.7%, P < 0.0001) than individuals in group A. Vasodepressor/mixed forms accounted for the majority of CSH responses in Group B (75%). When compared with the control group, CSH was still more common in Group B (B: 66.7% vs control: 17.6%, P < 0.0001) but not in Group A (A: 18.2% vs control: 17.6%, P = 1.000).
Conclusions: The prevalence of CSH is increased in elderly patients with hip fractures, only in those who present with an unexplained fall and report a history of syncope or unexplained falls in the past. The vasodepressor/mixed forms account for the majority of CSH responses in the group of unexplained fallers.
