Comparative effectiveness of fragility fracture integrated rehabilitation management for elderly individuals after hip fracture surgery: A study protocol for a multicenter randomized controlled trial

Multidisciplinary rehabilitation for older people with hip fractures

BACKGROUND

Hip fracture is a major cause of morbidity and mortality in older people, and its impact on society is substantial. After surgery, people require rehabilitation to help them recover. Multidisciplinary rehabilitation is where rehabilitation is delivered by a multidisciplinary team, supervised by a geriatrician, rehabilitation physician or other appropriate physician. This is an update of a Cochrane Review first published in 2009.

OBJECTIVES

To assess the effects of multidisciplinary rehabilitation, in either inpatient or ambulatory care settings, for older people with hip fracture.

SEARCH METHODS

We searched the Cochrane Bone, Joint and Muscle Trauma Group Specialised Register, CENTRAL, MEDLINE and Embase (October 2020), and two trials registers (November 2019).

SELECTION CRITERIA

We included randomised and quasi-randomised trials of post-surgical care using multidisciplinary rehabilitation of older people (aged 65 years or over) with hip fracture. The primary outcome - 'poor outcome' - was a composite of mortality and decline in residential status at long-term (generally one year) follow-up. The other 'critical' outcomes were health-related quality of life, mortality, dependency in activities of daily living, mobility, and related pain.

DATA COLLECTION AND ANALYSIS

Pairs of review authors independently performed study selection, assessed risk of bias and extracted data. We pooled data where appropriate and used GRADE for assessing the certainty of evidence for each outcome.

MAIN RESULTS

The 28 included trials involved 5351 older (mean ages ranged from 76.5 to 87 years), usually female, participants who had undergone hip fracture surgery. There was substantial clinical heterogeneity in the trial interventions and populations. Most trials had unclear or high risk of bias for one or more items, such as blinding-related performance and detection biases. We summarise the findings for three comparisons below. Inpatient rehabilitation: multidisciplinary rehabilitation versus 'usual care' Multidisciplinary rehabilitation was provided primarily in an inpatient setting in 20 trials. Multidisciplinary rehabilitation probably results in fewer cases of 'poor outcome' (death or deterioration in residential status, generally requiring institutional care) at 6 to 12 months' follow-up (risk ratio (RR) 0.88, 95% confidence interval (CI) 0.80 to 0.98; 13 studies, 3036 participants; moderate-certainty evidence). Based on an illustrative risk of 347 people with hip fracture with poor outcome in 1000 people followed up between 6 and 12 months, this equates to 41 (95% CI 7 to 69) fewer people with poor outcome after multidisciplinary rehabilitation. Expressed in terms of numbers needed to treat for an additional harmful outcome (NNTH), 25 patients (95% CI 15 to 100) would need to be treated to avoid one 'poor outcome'. Subgroup analysis by type of multidisciplinary rehabilitation intervention showed no evidence of subgroup differences. Multidisciplinary rehabilitation may result in fewer deaths in hospital but the confidence interval does not exclude a small increase in the number of deaths (RR 0.77, 95% CI 0.58 to 1.04; 11 studies, 2455 participants; low-certainty evidence). A similar finding applies at 4 to 12 months' follow-up (RR 0.91, 95% CI 0.80 to 1.05; 18 studies, 3973 participants; low-certainty evidence). Multidisciplinary rehabilitation may result in fewer people with poorer mobility at 6 to 12 months' follow-up (RR 0.83, 95% CI 0.71 to 0.98; 5 studies, 1085 participants; low-certainty evidence). Due to very low-certainty evidence, we have little confidence in the findings for marginally better quality of life after multidisciplinary rehabilitation (1 study). The same applies to the mixed findings of some or no difference from multidisciplinary rehabilitation on dependence in activities of daily living at 1 to 4 months' follow-up (measured in various ways by 11 studies), or at 6 to 12 months' follow-up (13 studies). Long-term hip-related pain was not reported. Ambulatory setting: supported discharge and multidisciplinary home rehabilitation versus 'usual care' Three trials tested this comparison in 377 people mainly living at home. Due to very low-certainty evidence, we have very little confidence in the findings of little to no between-group difference in poor outcome (death or move to a higher level of care or inability to walk) at one year (3 studies); quality of life at one year (1 study); in mortality at 4 or 12 months (2 studies); in independence in personal activities of daily living (1 study); in moving permanently to a higher level of care (2 studies) or being unable to walk (2 studies). Long-term hip-related pain was not reported. One trial tested this comparison in 240 nursing home residents. There is low-certainty evidence that there may be no or minimal between-group differences at 12 months in 'poor outcome' defined as dead or unable to walk; or in mortality at 4 months or 12 months. Due to very low-certainty evidence, we have very little confidence in the findings of no between-group differences in dependency at 4 weeks or at 12 months, or in quality of life, inability to walk or pain at 12 months.

AUTHORS' CONCLUSIONS

In a hospital inpatient setting, there is moderate-certainty evidence that rehabilitation after hip fracture surgery, when delivered by a multidisciplinary team and supervised by an appropriate medical specialist, results in fewer cases of 'poor outcome' (death or deterioration in residential status). There is low-certainty evidence that multidisciplinary rehabilitation may result in fewer deaths in hospital and at 4 to 12 months; however, it may also result in slightly more. There is low-certainty evidence that multidisciplinary rehabilitation may reduce the numbers of people with poorer mobility at 12 months. No conclusions can be drawn on other outcomes, for which the evidence is of very low certainty. The generally very low-certainty evidence available for supported discharge and multidisciplinary home rehabilitation means that we are very uncertain whether the findings of little or no difference for all outcomes between the intervention and usual care is true. Given the prevalent clinical emphasis on early discharge, we suggest that research is best orientated towards early supported discharge and identifying the components of multidisciplinary inpatient rehabilitation to optimise patient recovery within hospital and the components of multidisciplinary rehabilitation, including social care, subsequent to hospital discharge.

Effectiveness of a Home-Based Fragility Fracture Integrated Rehabilitation Management (FIRM) Program in Patients Surgically Treated for Hip Fractures

Background: The purpose of this study was to investigate the effectiveness of a home-based fragility fracture integrated rehabilitation management (H-FIRM) program following an inpatient FIRM (I-FIRM) program in patients surgically treated for hip fracture. Methods: This nonrandomized controlled trial included 32 patients who underwent hip surgery for a fragility hip fracture. The patients were divided into two groups: a prospective intervention group (n = 16) and a historical control group (n = 16). The intervention group performed a nine-week H-FIRM program combined with the I-FIRM program. The historical control group performed the I-FIRM program only. Functional outcomes included Koval’s grade, Functional Ambulatory Category (FAC), Functional Independence Measure (FIM) locomotion, Modified Rivermead Mobility Index (MRMI), 4 m walking speed test (4MWT), and the Korean version of Modified Barthel Index (K-MBI). All functional outcomes were assessed one week (before I-FIRM), three weeks (before I-FIRM), and three months (after H-FIRM) after surgery. Results: Both groups showed significant and clinically meaningful improvements in functional outcomes over time. Compared with the control group, the intervention group showed clinically meaningful improvements in Koval’s grade, FAC, FIM locomotion, MRMI, 4MWT, and K-MBI from baseline to three months. Conclusion: H-FIRM may be an effective intervention for improving functional outcomes in older people after fragility hip fractures.

Association between sarcopenia and fall characteristics in older adults with fragility hip fracture

INTRODUCTION

Sarcopenia is known as a risk factor for falls and hip fracture, and understanding fall characteristics is important for the fall-prevention programs. The aim of this study is to investigate whether sarcopenia is associated with fall characteristics in older adults with fragility hip fracture.

METHODS

A cross-sectional study was conducted in 147 patients over 65 years of age who had undergone a two-week postoperative rehabilitation for hip fracture. Fall characteristics included the fall type, direction and location. Fall types were categorized into two groups: fragile falls, leg weakness during walking, changing positions or standing; non-fragile falls, slipping or tripping while walking. Correlations between sarcopenia and fall characteristics, and of fall type with sarcopenia and fall characteristics were analyzed. Logistic regression analyzes were used to identify independent risk factors for fragile falls.

RESULTS

Sarcopenia was significantly correlated with fragile falls (r = .222, p = .007) and was more prevalent in the fragile fall group than the non-fragile fall group (53.5% vs. 32.9%). Sarcopenia (OR = 2.354, 95% CI 1.177-4.709, p = .016), moderate comorbidities (OR = 3.572, 95% CI 1.109-11.501, p = .033) and severe comorbidities (OR = 5.396, 95% CI 1.476-19.729, p = .011) by the Charlson Comorbidity Index were significant independent risk factors for fragile falls.

CONCLUSIONS

Sarcopenia was correlated with fragile falls; moreover, it was a risk factor for all of these fall types in older adults with fragility hip fracture. Based on these associations, targeted fall-prevention programs for older adults with sarcopenia, a high risk factor of falls and fractures, could help reduce the incidence rates of falls and fragility hip fracture.

A two-year multicenter point prevalence study of older patients with hip fractures admitted to rehabilitation units in Italy

PURPOSE

To date in Italy we do not have sufficient information on the rehabilitation process of older patients with hip fractures especially in the context of dementia. The main aims of the study were to gather information on the characteristics of older patients with hip fracture admitted to rehabilitation units with a specific focus on geriatric syndromes and the rehabilitation process.

METHODS

A national multi-center "point prevalence study" was conducted in Italy over two index days in 2017 and 2018. All patients aged 70 years and older hospitalized on the index day in Rehabilitation Units after a hip fracture were eligible.

RESULTS

A total of 615 patients were included. Most of the hospitals involved were from northern Italy, to a lesser extent from central and from southern Italy. The mean age was 83.08 ± 7.9 years. Almost half of the patients lived alone before the hip fracture. Most of the falls happened at home and while walking. The prevalence of delirium, dementia and malnutrition was 9.1%, 36.6%, and 19.3%, respectively. Antidepressants were prescribed in 27% of the population. The multidisciplinary team was activated as follows: occupational therapist in 18.9% of the cases, psychologists in 14.5%, social workers in 15.3%, and speech therapists in 6.5%.

CONCLUSION

The study allowed the collection of data on a relatively large sample of older patients with hip fracture showing the possible current limitations in the correct management of geriatric syndromes in this frail population. Future multicenter longitudinal studies are required to further study this population.

Effects of fragility fracture integrated rehabilitation management on mobility, activity of daily living and cognitive functioning in elderly with hip fracture

OBJECTIVE

To determine the effectiveness of Fragility Fracture Integrated Rehabilitation Management (FIRM) on mobility, activity of daily living and cognitive functioning in elderly with hip fracture.

METHODS

A randomized control trial was conducted at Seoul National University Bundang Hospital, South Korea from August 2017 to January 2018. Patients of both genders with the age 65-95 years, diagnosed cases of hip fracture specifically fractures neck of femur, intertrochanteric, subtrochantric, patients who got bipolar hemiarthroplasty, total hip replacement arthroplasty, reduction and internal fixation were included in this study. A total of n=39 sample was collected through non probability convenience sampling technique and randomly divided into Fragility Integrated Rehabilitation Management (FIRM) group (n=20) and Conventional Physical therapy (CPT) group (n=19). The data was collected through KOVAL for walking ability, modified barthal index (MBI) for behaviors related to activities of daily living (ADLS) and mini mental status examination (MMSE) for cognitive functions at baseline on 2nd postoperative day and after 10th FIRM session on 15th postoperative day.

RESULTS

The mean age of study participants was 82.07±6.00 years. The post intervention comparison did not show any significant difference (p>0.05) in walking ability, overall ADLs and cognitive functioning. But FIRM group showed significant improvement in stair climbing {0(5) ver. 2(7.5), p=0.049} and ambulation or walker use {8(5) ver. 2(4), p=0.037}, as compared to CPT group.

CONCLUSION

Both groups improved in indoor mobility with walker and crutches as well as activities of daily living. But FIRM showed more improving ambulation with walker and stair climbing. While cognitive functioning was observed only in FIRM group.

Phase angle as a predictor of functional outcomes in patients undergoing in-hospital rehabilitation after hip fracture surgery

OBJECTIVES

To evaluate the association between the phase angle and functional outcomes in patients after in-hospital postoperative rehabilitation for fragility hip fracture.

METHODS

A prospective observational study was conducted in 68 patients over 65 years of age who had undergone a two-week postoperative rehabilitation for hip fracture. Phase angle of the non-fractured limb was used to reduce the error caused by postoperative edema. Participants were divided into groups according to phase angle terciles. Multivariable linear regression models adjusted for relevant factors known to affect functional outcomes after hip fracture were performed to identify the association between phase angle of the non-fractured limb and functional outcomes at discharge as evaluated the Functional Ambulation Category and Berg Balance Scale.

RESULTS

The mean age of this study population was 81.9 ± 6.2 years and the average phase angle of the non-fractured limb was 3.6 ± 1.3°. The lowest tercile of phase angle (<3.0°) was independently associated with worse functional outcomes as measured by the Functional Ambulation Category and Berg Balance Scale at discharge (adjusted coefficient [β] = -0.287, P = 0.004; β = -0.172, P = 0.049, respectively) after adjusting for relevant covariates.

CONCLUSIONS

Low phase angle of the non-fractured limb was independently associated with worse functional outcomes at rehabilitation discharge in patients who undergoing hip fracture surgery. Phase angle may reflect both the pre-fracture body composition and functional status. It is a useful indicator for functional outcomes after postoperative rehabilitation for fragility hip fracture.

MiR-214 regulates fracture healing through inhibiting Sox4 and its mechanism

OBJECTIVE

To investigate the expression of micro ribonucleic acid (miR)-214 in the bone tissue and blood of patients with fragility fracture.

METHODS

The expression of miR-214 was detected via quantitative reverse transcription-polymerase chain reaction. The effect of miR-214 on proliferation and apoptosis of osteoblasts were detected via methyl thiazolyl tetrazolium assay and terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling staining.

RESULTS

The expression of miR-214 in the bone tissue and blood of patients with fragility fracture significantly declined. miR-214 could promote the proliferation of osteoblasts and inhibited the apoptosis of osteoblasts. miR-214 is involved in fracture healing through inhibiting Sox4 and promoting phosphorylation of PI3K/AKT pathway. The expression of BSP in cells treated with miR-214 mimics was significantly increased to 2.5-fold (p=0.0168), while the expression of BSP in cells treated with miR-214 AMO was significantly decreased, reduced to 0.3 times (p=0.0397). The expression of BMP2 in cells treated with miR-214 mimics was significantly increased to 2.5-fold (p=0.003), while the expression of BMP2 was significantly decreased in cells treated with miR-214 AMO, reduced to 0.3 times (p=0.0002). miR-214 can regulate the expression of Sox2, PI3K and AKT proteins.

CONCLUSION

MiR-214 regulates the proliferation, apoptosis, bone formation of osteoblasts and participate in the fracture healing process by inhibiting the expression of Sox4, which provided new ideas for clinical treatment of fracture healing.

Functional Outcomes of Fragility Fracture Integrated Rehabilitation Management in Sarcopenic Patients after Hip Fracture Surgery and Predictors of Independent Ambulation

OBJECTIVES

To compare the changes in the functional level of patients with versus without sarcopenia who received by fragility fracture integrated rehabilitation management (FIRM) after hip fracture (HF) surgery over a 6-month follow-up period and to identify variables influencing independent ambulation (IA) at 6 months after HF.

DESIGN

Prospective observational study.

SETTING

Three in-hospital rehabilitation setting.

PARTICIPANTS

Patients older than 65 years of age (N=80) categorized by the presence of sarcopenia.

INTERVENTION

The FIRM program during the-2 week hospital stay after surgery.

MEASUREMENTS

Main outcomes for ambulatory function (Koval score, Functional Ambulatory Category) and other secondary outcomes were measured at rehabilitation admission, at discharge, at 3 months and 6 months after surgery. Other secondary outcomes were measured. The possibility of IA at 6 months after surgery were also investigated.

RESULTS

Sarcopenia and non-sarcopenia patients did not differ significantly in terms of changes in ambulation or other functions over a 6-month follow-up (p < 0.001 or p = 0.001). The two groups did not differ significantly in terms of final functional status (6 months). The IA ratios of the two groups did not significantly differ at 6 months after surgery (sarcopenia [54.3%] and non-sarcopenia [64.5%]). IA before fracture (p = 0.039) and age (≥80 years) (p = 0.03) were independent predictors and sarcopenia was not a predictor for the possibility of IA at 6-months after surgery.

CONCLUSIONS

The FIRM program was effective for promoting functional recovery in older patients with fragility HF, either with or without sarcopenia. The present findings provide evidence of the pressing need for integrated rehabilitation management in fragility fracture care to improve functional recovery in patients with sarcopenia.

Effectiveness of the computerized balance rehabilitation after hip fracture surgery: A study protocol of a prospective and open-label clinical trial

INTRODUCTION

Although balance problems in older populations are directly correlated with hip fractures, the overall physical gain afforded by balance rehabilitation itself has not yet been fully investigated. Here we describe a protocol for an open-label clinical trial to evaluate the effectiveness of computer-based balance-specific exercise (BSE) on the performance and balance of elderly women who underwent hip fracture surgery (HFS).

METHODS AND ANALYSIS

Elderly female patients (≥65 years old) who underwent surgery for femoral neck, intertrochanteric, or subtrochanteric fracture regardless of surgery type will be included. The BSE will be conducted using a computed posturographic system for a 2-week intervention period following HFS. The primary outcome of this study is Berg balance scale score. All functional outcomes will be measured at 1 and 3 weeks and at 3 and 6 months after the surgical intervention. The data will be analyzed using the intention-to-treat principle.
