Inpatient rehabilitation outcome after hip fracture surgery in elderly patients: a prospective cohort study of 946 patients

A multicenter study of 1-year mortality and walking capacity after spinal fusion surgery for cervical fracture in elderly patients

Background

The 1-year mortality and functional prognoses of patients who received surgery for cervical trauma in the elderly remains unclear. The aim of this study is to investigate the rates of, and factors associated with mortality and the deterioration in walking capacity occurring 1 year after spinal fusion surgery for cervical fractures in patients 65 years of age or older.

Methods

Three hundred thirteen patients aged 65 years or more with a traumatic cervical fracture who received spinal fusion surgery were enrolled. The patients were divided into a survival group and a mortality group, or a maintained walking capacity group and a deteriorated walking capacity group. We compared patients’ backgrounds, trauma, and surgical parameters between the two groups. To identify factors associated with mortality or a deteriorated walking capacity 1 year postoperatively, a multivariate logistic regression analysis was conducted.

Results

One year postoperatively, the rate of mortality was 8%. A higher Charlson comorbidity index (CCI) score, a more severe the American Spinal Cord Injury Association impairment scale (AIS), and longer surgical time were identified as independent factors associated with an increase in 1-year mortality. The rate of deterioration in walking capacity between pre-trauma and 1 year postoperatively was 33%. A more severe AIS, lower albumin (Alb) and hemoglobin (Hb) values, and a larger number of fused segments were identified as independent factors associated with the increased risk of deteriorated walking capacity 1 year postoperatively.

Conclusions

The 1-year rate of mortality after spinal fusion surgery for cervical fracture in patients 65 years of age or older was 8%, and its associated factors were a higher CCI score, a more severe AIS, and a longer surgical time. The rate of deterioration in walking capacity was 33%, and its associated factors were a more severe AIS, lower Alb, lower Hb values, and a larger number of fused segments.

Post-hip fracture rehabilitation outcomes of diabetic and non-diabetic elderly patients

BACKGROUND

Although patients with diabetes mellitus (DM) are at higher risk of hip fracture, data regarding the effect of DM on rehabilitation outcomes are limited.

METHODS

A retrospective single-centre study was conducted comparing elderly diabetic and non-diabetic patients with recent hip fracture, admitted to geriatric rehabilitation, 2014-2019. The functional independence measure (FIM) was used to assess physical and cognitive function. Delta-FIM was calculated by subtracting admission FIM from discharge FIM. One-year mortality, hospitalizations and fractures were assessed.

RESULTS

Six-hundred-thirty elderly patients, post-hip fracture were included, mean age 83 ± 7 years, 70.5% (444) women. Among them, 193 (30.6%) had type 2 DM, HbA1c 6.6 ± 1.25%. They were younger (81.4 vs. 84.3 years, p < .01) and had more co-morbidities including hypertension, chronic kidney disease, ischaemic heart disease and cerebrovascular disease. Baseline cognitive and motor scores were similar between groups. Delta motor-FIM was similar between diabetics and non-diabetics (15.56 ± 8.95 and 14.78 ± 8.79, respectively, p = .35). Multivariate regression analysis showed motor-FIM improvement was associated with higher BMI, male sex, and younger age, but not with DM. Cognitive FIM did not change significantly during rehabilitation in either group. Similar rates of patients were discharged to nursing care facilities. There was no difference in 1-year hospitalization or fracture rates. One-year, all-cause mortality was higher among diabetic patients (10.9 vs. 6.6%, respectively, p = .07). After adjusting for covariates, DM was associated with higher mortality risk (odds ratio = 2.78, 95% CI [1.28, 6.04], p = .01).

CONCLUSIONS

Patients with well-controlled DM have similar post-hip fracture rehabilitation potential compared with non-diabetics, despite more co-morbidities. These results support resource allocation for post-hip fracture rehabilitation among patients with DM. The higher 1-year all-cause mortality in patients with DM reinforces the need for close follow-up and control of co-morbidities in this population.

Optimization of transdisciplinary management of elderly with femur proximal extremity fracture: A patient-tailored plan from orthopaedics to rehabilitation

Fractures of femur proximal extremity (FFPE) are the most common fragility fractures requiring hospitalization, with a high risk of mortality, low independence in the activities of daily living and severe consequences on health-related quality of life. Timing for surgery has a key role in the management of elderly patients with FFPE as recommended by the Australian and New Zealand guidelines and the National Institute for Health and Care Excellence guidelines. Early surgery (within 48 h from hospital admission) allows significant benefits in terms of lower rates of postoperative complications and risk of death and can provide better functional outcomes. Therefore, time for surgery could be considered as a comorbidity marker. The choice between conservative or surgical approach surprisingly seems to be still not strongly supported by available literature, but it seems that both 30 d and 1 year risk of mortality is higher with the conservative treatment rather than with surgery. In light of these considerations, the optimization of FFPE management care is mandatory to improve functional outcomes and to reduce sanitary costs. Albeit it is widely accepted that transdisciplinary approach to patients suffering from FFPE is mandatory to optimize both short-term and long-term outcomes, the feasibility of a comprehensive approach in clinical practice is still a challenge. In particular, the large variability of figures involved could be considered both a resource and an additional disadvantage taking into account the difficulty to coordinate multidisciplinary approach covering care in all settings. Therefore, the aim of the present article was to summarize current evidence supporting transdisciplinary management of patients with FFPE, highlighting the benefits, feasibility and limitations of this approach.

Clinical prediction model for postoperative ambulatory ability outcomes in patients with trochanteric fractures

INTRODUCTION

Regaining independent ambulatory ability is one of the primary goals of treatment in patients with trochanteric fractures. This study aimed to develop and evaluate the discriminative accuracy of a clinical prediction model for ambulatory ability outcomes 3 months after surgery for trochanteric fractures.

METHODS

This retrospective cohort study included 346 patients treated with intramedullary nailing for trochanteric fractures who had independent ambulatory ability before their injury. Multiple regression models with preoperative and postoperative factors were used to predict ambulatory ability outcomes at 3 months. A clinical prediction model (CPM) was created based on a decision tree developed using a chi-square automatic interaction detector technique.

RESULTS

Three months after surgery, 263 (76.0%) and 83 (24.0%) patients regained and lost independent ambulatory ability, respectively. Univariate analysis showed that the Barthel index (BI) total score at 2 weeks predicted the ambulatory ability outcome at 3 months with good discriminative accuracy (area under the receiver operating characteristic curve [AUROC]: 0.819; 95% confidence interval [CI]: [0.769, 0.868], cut-off value: 22.5; sensitivity: 69.5%; specificity: 82.3%). Multiple logistic regression analysis showed that preoperative factors (residence before injury, diagnosis of dementia, and serum albumin at admission) and postoperative factors (BI total score at 2 weeks) predicted ambulatory ability outcomes at 3 months (AUROC: 0.710; 95%CI: [0.636, 0.783]; sensitivity: 91.3%; specificity: 41.8%). The CPM with the BI total score at 2 weeks (≤10; 10<, ≤50; >50 points) and dementia status (present; absent) had a moderate discriminative accuracy (AUROC: 0.676; 95%CI: [0.600, 0.752]; sensitivity: 94.7%; specificity: 40.5%).

CONCLUSIONS

We developed a CPM with moderate accuracy to predict ambulatory ability outcomes in patients 3 months after surgery for trochanteric fractures. Our results demonstrate the importance of the BI score measured soon after surgery and dementia status for the prediction of postoperative ambulation.

Impact of place of residence, frailty and other factors on rehabilitation outcomes post hip fracture

BACKGROUND

Following hip fracture surgery, patients from residential care are frequently excluded from inpatient rehabilitation. We aimed to assess the impact of place of residence and other factors such as frailty on rehabilitation outcomes after hip fracture surgery.

METHODS

Retrospective cohort study. Outcome measures included Functional Independence Measure efficiency, discharge destination and recovery of pre-fracture mobility. Univariable and multivariable linear or logistic regression analyses were performed.

SETTING

One general rehabilitation and two geriatric evaluation and management wards in a large public tertiary teaching hospital.

PARTICIPANTS

A total of 844 patients who underwent inpatient rehabilitation after hip fracture surgery from 2010 to 2018.

RESULTS

There were 139 (16%) patients from residential care. Being from residential care was not an independent predictor of poor outcomes. Premorbid frailty (Clinical Frailty Scale) was the strongest independent predictor of poorer Functional Independence Measure efficiency, inability to recover pre-fracture mobility and return to community dwelling. Dementia and delirium were also independently predictive of poor outcomes across all measures. Age > 90 years was independently predictive of inability to recover pre-fracture mobility and return to community dwelling.

CONCLUSION

Being from residential care is not independently associated with poor outcomes following inpatient rehabilitation after hip fracture surgery and should not be the basis for excluding these patients from rehabilitation. Major predictors of poorer outcomes include premorbid frailty, dementia, delirium and age > 90 years. If able and motivated, those with potentially reversible functional limitations should be given the opportunity to participate in inpatient rehabilitation as even small gains can have a significant impact on quality of life.

Preoperative hypoalbuminemia: Poor functional outcomes and quality of life after hip fracture surgery

AIMS

Hip fracture patients have severe deterioration of their quality of life and function after their injury. Markers of malnutrition such as low albumin and low body mass index (BMI) have been shown to increase mortality and complication rates but their effect on recovery of quality of life and function after hip fracture surgery is unclear. The main aim of this paper is to further investigate if low albumin affects recovery after hip fracture surgery, while additionally studying low BMI as a possible risk factor for poor recovery.

PATIENTS AND METHODS

Retrospective analysis of 971 patients who underwent surgery for fragility hip fractures between January 2012 and December 2016 was performed. Demographic data, preoperative serum albumin and haemoglobin levels, BMI, Charlson Comorbidity Index (CCI), type of surgery (fixation vs replacement) and site of surgery were obtained. Patients were assessed using the Parker Mobility Scale (PMS), Harris Hip Score(HHS), Medical Outcomes Study 36-item Short-Form Health Survey (SF36) at pre-fracture, 6 weeks and 6 months after surgery. HHS was not available pre-operatively. Patients were grouped according to their albumin levels (low ≤35 g/L or normal) and BMI (underweight <18.5 or normal). Univariate and multivariate analyses were performed to examine the association between albumin and BMI and 6-month scores.

RESULTS

On univariate analysis, patients with low albumin ≤35 g/L had lower baseline PMS and SF36 Physical Functioning (PF) score. On multivariate analysis, preoperative hypoalbuminemia was associated with lower 6-month HHS, PMS and SF36 PF scores even after accounting for baseline scores and other confounders. BMI had no effect on 6-month scores.

CONCLUSION

Low albumin (≤35 g/L) is prevalent in elderly hip fracture patients and is associated with slower recovery of function and quality of life after surgery. Low albumin can be a useful prognostic tool to identify patients with poor recovery for further intervention or rehabilitation after hip fracture surgery.

Handgrip strength: a reliable predictor of postoperative early ambulation capacity for the elderly with hip fracture

Backgrounds

A common sequela of hip fracture is loss of ambulation capacity. Prediction of postoperative ambulation capacity is important for surgical and rehabilitation decision making. Handgrip strength is a quick and convenient tool for evaluating postoperative functional ability and outcome in variety of clinical conditions for the elderly and is associated with the use of walking aids. We propose that handgrip strength may be a good predictor for postoperative early ambulation. The purpose of our study was to investigate the contribution of handgrip strength in the prediction of postoperative early ambulation capacity in elderly hip fracture patients.

Methods

Clinical data of patients with low-energy hip fractures who received surgery from Jan 2018 to Dec 2019 were prospectively collected. The correlations of ambulation time with complication rate, age, gender, injured side, fracture classifications, surgical procedure, body mass index (BMI), and handgrip strength were analyzed.

Results

Sixty-three hip fracture patients were included in this study. Patients whose ambulation time was less than 3 days after the operation had significantly fewer postoperative complications (P = 0.006). Handgrip strength showed the strongest correlation with postoperative early ambulation capacity (P = 0.004). The handgrip strength threshold value for early ambulation was found to be 20.5 kg for male patients and 11.5 kg for female patients.

Conclusion

Handgrip strength testis a quick and convenient tool for predicting postoperative early ambulation capacity. In elderly Asians, male patients with a handgrip strength above 20.5 kg and female patients with a handgrip strength above 11.5 kg suggest a high likelihood of early postoperative ambulation and a lower risk of complications after the hip surgery.

Intensive Inpatient vs. Home-Based Rehabilitation After Hip Fracture in the Elderly Population

Background: As the population ages, the rate of hip fractures and the need for rehabilitation increases. Home-based rehabilitation (HBR) is an alternative to classic inpatient rehabilitation (IR), which is an expensive framework with non-negligible risks.

Methods: A retrospective study of patients 65 years and above following surgery to repair a hip fracture who underwent HBR or IR between 2016 and 2019. The two rehabilitation frameworks were compared for rehabilitation outcome and factors predicting successful rehabilitation. The outcome was determined with the Montebello Rehabilitation Factor Score-Revised (MRFS-R).

Results: Data were collected for 235 patients over 3 years. The mean age was 81.3 ± 8.0 and 172 (73.3%) were women. Of these, 138 underwent IR and 97 HBR. The HBR group had better family support and fewer lived alone. There were also differences in the type of fracture and surgery. The medical condition of the IR group was more complex, as reflected in a higher Charlson's comorbidity scores, higher rates for delirium and more infectious complications, a lower Norton score, lower serum hemoglobin, and albumin levels, and higher serum creatinine and urea levels. It also had a more significant functional decline after surgery and required a longer rehabilitation period. However, no difference was found in the rehabilitation outcomes between the two groups (MRFS-R ≥ 50). The independent predictors for rehabilitation in the IR group were serum albumin level, comorbidity, and cognitive state. There were no independent predictors in the HBR group.

Conclusions: In this retrospective study, there was no significant difference in short-term rehabilitation outcomes between the HBR and IR groups event though the patients in the IR group were medically more complex. This result should be taken into account when planning rehabilitation services after hip fracture and tailoring rehabilitation frameworks to patients.

Heart failure assessed based on plasma B-type natriuretic peptide (BNP) levels negatively impacts activity of daily living in patients with hip fracture

Several studies have shown that nutrition and muscle strength were associated with functional recovery in patients with hip fracture. However, the impact of heart failure on the improvement of activity of daily living (ADL) in patients with hip fracture have not been fully investigated. The purpose was investigating the effect of heart failure on the ADL improvement by rehabilitation in patients with hip fracture. A total of 116 patients with hip fracture discharged from our convalescent rehabilitation ward were studied. Heart failure was assessed based on plasma B-type natriuretic peptide (BNP) levels on admission. ADL was assessed based on rehabilitation effectiveness (REs), which was calculated using the FIM instrument. Clinical, demographic, and nutritional variables were measured. Multiple regression analysis was performed with REs as the dependent variable; variables showing significant correlation with REs in univariate analyses were selected as independent variables. Based on plasma BNP levels, we assigned 39 patients to a Low group: 22 (17−25) median (interquartile) pg/mL, 39 to a Middle group: 52 (42−65) pg/mL, and 38 to a High group: 138 (93−209) pg/mL. REs, handgrip strength, Hb, albumin, and GNRI were higher and age was younger in the Low group than High group (each p < 0.01, respectively). Multiple linear regression analysis revealed that age (p < 0.05), sex (p < 0.05), handgrip strength (p < 0.01), FOIS at admission (p < 0.01), rehabilitation time per day (p < 0.01), and BNP (p < 0.05) were significantly associated with REs. The effect of rehabilitation on ADL improvement was significantly blunted in the High group compared to the Low group. In conclusion, these results suggest that heart failure assessed based on plasma BNP levels negatively impacts improvements in ADL achieved through rehabilitation in patients with hip fracture.

Holistic Management of Older Patients With Hip Fractures

As the silver tsunami hits the world, older patients with hip fractures are expected to increase to 6.3 million by the year 2050, of which the majority will occur in Asia. The estimated global cost of hip fractures in the year 2050 is estimated to reach U.S. $130 billion. Hence, in addition to implementation of prevention strategies, it is important to develop an optimal model of care for older patients with hip fracture to minimize the huge medical and socioeconomic burden, especially in rapidly aging nations. This review summarizes the complications of hip fractures, importance of comprehensive geriatric assessment, and multidisciplinary rehabilitation, as well as predictors of rehabilitation outcome in older patients with hip fracture.

Enhanced rehabilitation and care models for adults with dementia following hip fracture surgery

BACKGROUND

Hip fracture is a major injury that causes significant problems for affected individuals and their family and carers. Over 40% of people with hip fracture have dementia or cognitive impairment. The outcomes of these individuals after surgery are poorer than for those without dementia. It is unclear which care and rehabilitation interventions achieve the best outcomes for these people. This is an update of a Cochrane Review first published in 2013.

OBJECTIVES

(a) To assess the effectiveness of models of care including enhanced rehabilitation strategies designed specifically for people with dementia following hip fracture surgery compared to usual care. (b) To assess for people with dementia the effectiveness of models of care including enhanced rehabilitation strategies that are designed for all older people, regardless of cognitive status, following hip fracture surgery, compared to usual care.

SEARCH METHODS

We searched ALOIS (www.medicine.ox.ac.uk/alois), the Cochrane Dementia and Cognitive Improvement Group Specialised Register, MEDLINE (OvidSP), Embase (OvidSP), PsycINFO (OvidSP), CINAHL (EBSCOhost), Web of Science Core Collection (ISI Web of Science), LILACS (BIREME), ClinicalTrials.gov, and the World Health Organization International Clinical Trials Registry Platform on 16 October 2019.

SELECTION CRITERIA

We included randomised and quasi-randomised controlled trials evaluating the effectiveness of any model of enhanced care and rehabilitation for people with dementia after hip fracture surgery compared to usual care.

DATA COLLECTION AND ANALYSIS

Two review authors independently selected trials for inclusion and extracted data. We assessed risk of bias of the included trials. We synthesised data only if we considered the trials to be sufficiently homogeneous in terms of participants, interventions, and outcomes. We used the GRADE approach to rate the overall certainty of evidence for each outcome.

MAIN RESULTS

We included seven trials with a total of 555 participants. Three trials compared models of enhanced care in the inpatient setting with conventional care. Two trials compared an enhanced care model provided in inpatient settings and at home after discharge with conventional care. Two trials compared geriatrician-led care in-hospital to conventional care led by the orthopaedic team. None of the interventions were designed specifically for people with dementia, therefore the data included in the review were from subgroups of people with dementia or cognitive impairment participating in randomised controlled trials investigating models of care for all older people following hip fracture. The end of follow-up in the trials ranged from the point of acute hospital discharge to 24 months after discharge. We considered all trials to be at high risk of bias in more than one domain. As subgroups of larger trials, the analyses lacked power to detect differences between the intervention groups. Furthermore, there were some important differences in baseline characteristics of participants between the experimental and control groups. Using the GRADE approach, we downgraded the certainty of the evidence for all outcomes to low or very low. The effect estimates for almost all comparisons were very imprecise, and the overall certainty for most results was very low. There were no data from any study for our primary outcome of health-related quality of life. There was only very low certainty for our other primary outcome, activities of daily living and functional performance, therefore we were unable to draw any conclusions with confidence. There was low-certainty that enhanced care and rehabilitation in-hospital may reduce rates of postoperative delirium (odds ratio 0.04, 95% confidence interval (CI) 0.01 to 0.22, 2 trials, n = 141) and very low-certainty associating it with lower rates of some other complications. There was also low-certainty that, compared to orthopaedic-led management, geriatrician-led management may lead to shorter hospital stays (mean difference 4.00 days, 95% CI 3.61 to 4.39, 1 trial, n = 162).

AUTHORS' CONCLUSIONS

We found limited evidence that some of the models of enhanced rehabilitation and care used in the included trials may show benefits over usual care for preventing delirium and reducing length of stay for people with dementia who have been treated for hip fracture. However, the certainty of these results is low. Data were available from only a small number of trials, and the certainty for all other results is very low. Determining the optimal strategies to improve outcomes for this growing population of patients should be a research priority.

Predictors of poor functional outcomes and mortality in patients with hip fracture: a systematic review

Background

Hip fracture is an important and prevalent medical condition associated with adverse outcomes. The aim of this article is to systematically review and summarise the predictors of poor functional outcomes and mortality for patients with hip fractures.

Methods

We conducted a systemic literature search using PubMed, EMBASE and Cochrane Library. We included English peer-reviewed cohort studies that examined predictors of poor functional outcomes (such as independence in Activities of Daily Living) and mortality for patients with hip fracture published in the past 15 years (from 1 Jan 2004 up to 30 May 2019). Two independent researchers evaluated the articles for eligibility. Consensus on the eligibility was sought and a third researcher was involved if there was disagreement. A standardised form was used to extract relevant data. The Newcastle-Ottawa Scale (NOS) was used to assess the quality of the included studies.

Results

We retrieved 4339 and included 81 articles. We identified two emerging predictors of poor functional outcomes and mortality for patients with hip fractures: low hand grip strength and frailty in line with an emerging concept of “physical performance”. The predictors identified in this systematic review can be grouped into 1) medical factors, such as presence of co-morbidities, high American Society of Anesthesiologists (ASA) grade, sarcopenia, 2) surgical factors including delay in operation (e.g. > 48 h), type of fracture s, 3) socio-economic factors which include age, gender, ethnicity, and 4) system factors including lower case-volume centers.

Conclusions

This systematic review identified multiple significant predictors of poor functional outcomes and mortality, with the hand grip strength and frailty being important emerging predictors in the most recent literature. These predictors would further inform healthcare providers of their patients’ health status and allow for early intervention for modifiable predictors.

Importance of Early Inpatient Geriatric Rehabilitation on Outcomes in Individuals on Dialysis

OBJECTIVE

To report short-term functional outcomes of patients incident to dialysis undergoing inpatient rehabilitation within 3 months of dialysis initiation.

DESIGN

Retrospective observation study using prospectively collected data.

SETTING

Single-center, hospital-based geriatric dialysis rehabilitation unit. All patients incident to hemodialysis admitted to the geriatric dialysis rehabilitation unit between May 2002 and April 2016 were identified using a retrospective observational design. Clinical and demographic data were collected prospectively and linked, using the unique hospital number and dates of admission and discharge, to FIM scores (used to assess functional recovery) at admission and discharge.

PARTICIPANTS

Patients (N=449; mean age ± SD, 74±9y) newly started on hemodialysis (within 3mo).

INTERVENTIONS

Inpatient rehabilitation care, short daily dialysis therapy with nephrologist support, and geriatrician assessment.

MAIN OUTCOMES

Change in FIM score; discharge location.

RESULTS

Patients were admitted within 3 months of hemodialysis initiation. The median length of stay in the rehabilitation program was 43 days (25th and 75th quartile, 33-55 days). Of those with complete data (n=370), 95% had improvement in FIM scores (median changes in total FIM score 25 [quartiles, 16, 33]; in motor FIM 23 [quartiles, 15, 32]; and in cognitive FIM 1 [quartiles, 0, 3], respectively). Most improvement was seen in transfer abilities, grooming, and mobility. A total of 324 patients (72%; 95% CI, 68%-76%) were discharged to a private home. An additional 11 were discharged to a seniors' residence.

CONCLUSION

The data suggest that older patients incident to dialysis with functional decline respond well to specialized rehabilitation care and suggest this may be a novel approach to dialysis initiation.

The association between effectiveness of clinical supervision of allied health professionals and improvement in patient function in an inpatient rehabilitation setting

Purpose: Clinical supervision is widely accepted as an important element of practice for allied health professionals to ensure a high quality of patient care. However, it is unknown whether effective clinical supervision of allied health professionals improves patients' outcomes. This study investigated whether effective clinical supervision of allied health professionals is associated with improved patient functional independence. Methods: A prospective longitudinal study design and multi-level regression analysis were used to explore the association between effective clinical supervision and patient functional independence. The effectiveness of clinical supervision was assessed using the Manchester Clinical Supervision Scale. Functional improvement in patients treated by allied health professionals was measured utilising the mobility and self-care subscales of the functional independence measure.Results: Physiotherapists (n = 27) and occupational therapists (n = 26) in inpatient rehabilitation were recruited and the medical records of their patients (n = 1846) audited. The effectiveness of clinical supervision of physiotherapists was positively associated with improvement in personal care. Therapist variables accounted for less than 2.5% of the variation in patient improvement in functional independence.Conclusions: Effectiveness of a reflective model of clinical supervision of physiotherapists and occupational therapists was not associated with an improvement in their patients' mobility or personal care, respectively.Implications for rehabilitationEffective clinical supervision of physiotherapists and occupational therapists using a reflective model of practice is a poor predictor of improved functional independence in rehabilitation inpatients.Patient variables, such as the intensity of therapy, were more important predictors of patient functional improvement than effective clinical supervision.Initiatives aimed at increasing intensity of therapy will likely have a greater effect on improving patient functional independence compared with initiatives aimed at improving the effectiveness of clinical supervision using a reflective model of practice.Initiatives to improve the effectiveness of clinical supervision in improving quality of care could explore the use of a direct model of practice where supervisors directly observe and support supervisees during patient treatment sessions.

Hip fractures - Treatment and functional outcome. The development over 25 years

BACKGROUND

Nearly 18,000 individuals suffer from hip fracture in Sweden each year. The choice in operation method for femoral neck fractures has changed over the years as well as the overall management. Functional outcome after hip fracture is affected by several factors and the overall functional level for old people in Sweden has improved over the last decades.

OBJECTIVE

To describe and analyse the functional outcome and choice of operation method for hip fracture patients between 1988 and 2012.

PATIENTS AND METHODS

All patients with cervical or trochanteric hip fracture treated at Lund University Hospital from 1988 until 2012 were collected from the National Quality Register for hip fracture patients, RIKSHÖFT. Patients younger than 50 years and those with pathological fractures were excluded. Data regarding patient characteristics, fracture type, operation method and housing, walking ability and use of walk aids prefracture and at 4-months follow-up was retrieved and analysed.

RESULTS

For this study 8723 patients were included with a mean age of 81.6 (men 79.3, women 82.5). The mean age significantly increased over the period studied. Sliding hip screw dominates as method of choice for the trochanteric fractures. For the cervical fractures there is a clear shift from osteosynthesis to arthroplasty. There is a significant decrease in functional outcome at follow-up compared to prefracture. No significant trend change can be seen over 25 years. Functional outcome are worse for the patients with trochanteric fracture.

CONCLUSION

Although there have been changes in operation methods for hip fractures and the management has developed, our study does not show any effect on functional outcome over a 25-year period. The medical condition of these patients with increasing age seems to counteract efforts to improve the care.

Predictors of recovering ambulation after hip fracture inpatient rehabilitation

Background

Despite progress in surgery and care, hip fracture (HF) remains a catastrophic event, burdened with high risk of mortality and disability. This study aims at identifying predictors of recovering ambulation after intensive inpatient rehabilitation within the Tuscany Region HF rehabilitation pathway.

Methods

All HF patients referred from acute care to the two Massa-Carrara Rehabilitation facilities January 2015–June 2017 were enrolled. Comorbidity Total Score (CIRS) defined high- or low-care setting referral. Recovery of ambulation, with or without aid, (assessed by SAHFE) was the primary outcome. Personal data, comorbidity, cognitive (MMSe) and pre-fracture function (mRANKIN) were recorded on admission. Outcomes included hospital readmission, length of stay (LOS) and home discharge. Urinary catheter, bedsores, disability (modified Barthel Index-mBI), communication disability (CDS), trunk control (TCT), pain (NRS), and ambulation were recorded (admission-discharge).

Results

Of 352 patients enrolled (age 83.9 ± 7.1; 80% women), 1 died and 6 were readmitted to acute-care hospital; 97% patients referred to high-care, and 64% referred to low-care, presented moderate-high comorbidity on admission. Median LOS was 22 days; 95% patients were discharged back home; daily functional gain (mBIscore/LOS) was 1.3 ± 0.7. Patients who recovered ambulation on discharge were 84%. Older age, higher comorbidity, bladder catheter, impaired trunk control, worse cognitive and functional status on admission, and pre-fracture disability were associated to poor outcome, but only higher comorbidity and impaired communication on admission predicted failure to recover ambulation on discharge.

Conclusion

In HF patients entitled to intensive inpatient rehabilitation, moderate-high comorbidity and impaired communication are frequent findings and predict rehabilitation failure.

Stability of extracapsular hip fracture: Does it affect rehabilitation outcome of post-acute patients?

BACKGROUND

Various factors have been shown to affect rehabilitation outcome of hip fractured patients. The degree of extracapsular fracture stability may also affect functional recovery. The aim of our study was to assess the relationship between extracapsular hip fracture stability and rehabilitation outcome in a post-acute setting.

METHODS

A retrospective cohort study of 144 hip fractured patients was carried out in a post-acute geriatric rehabilitation center from 1/2014 to 6/2015. The main outcome measures were the Functional Independence Measure (FIM) instrument, motor FIM (mFIM), Montebello Rehabilitation Factor Score (MRFS) on the mFIM and length of stay (LOS). The associations between patients with stable vs. unstable and clinical, demographic and comorbidity variables, were assessed by the Mann-Whitney U and chi-square tests. A multiple linear regression model was used to estimate the association between fracture stability and LOS score after controlling for sociodemographic characteristics and chronic diseases.

RESULTS

Rehabilitation outcomes (FIM and mFIM score changes, mFIM MRFS) were found independent of extracapsular hip fracture stability. Patients with an unstable fracture presented with a significantly longer LOS compared with a stable fracture (p = .008). Multiple linear regression analysis showed that fracture stability was significantly associated with LOS after adjustment for confounding demographic, clinical and functional variables (p = .009).

CONCLUSION

Patients with unstable extracapsular hip fractures may require a prolonged rehabilitation period in order to achieve the same functional gain as patients with stable fractures.

Developing a multidisciplinary rehabilitation package following hip fracture and testing in a randomised feasibility study: Fracture in the Elderly Multidisciplinary Rehabilitation (FEMuR)

BACKGROUND

Proximal femoral fracture is a major health problem in old age, with annual UK health and social care costs of £2.3B. Rehabilitation has the potential to maximise functional recovery and maintain independent living, but evidence of clinical effectiveness and cost-effectiveness is lacking.

OBJECTIVES

To develop an enhanced community-based rehabilitation package following surgical treatment for proximal femoral fracture and to assess acceptability and feasibility for a future definitive randomised controlled trial (RCT) and economic evaluation.

DESIGN

Phase I - realist review, survey and focus groups to develop the rehabilitation package. Phase II - parallel-group, randomised (using a dynamic adaptive algorithm) feasibility study with focus groups and an anonymised cohort study.

SETTING

Recruitment was from orthopaedic wards of three acute hospitals in the Betsi Cadwaladr University Health Board, North Wales. The intervention was delivered in the community following hospital discharge.

PARTICIPANTS

Older adults (aged ≥ 65 years) who had received surgical treatment for hip fracture, lived independently prior to fracture, had mental capacity (assessed by the clinical team) and received rehabilitation in the North Wales area.

INTERVENTIONS

Participants received usual care (control) or usual care plus an enhanced rehabilitation package (intervention). Usual care was variable and consisted of multidisciplinary rehabilitation delivered by the acute hospital, community hospital and community services depending on need and availability. The intervention was designed to enhance rehabilitation by improving patients' self-efficacy and increasing the amount and quality of patients' practice of physical exercise and activities of daily living. It consisted of a patient-held information workbook, a goal-setting diary and six additional therapy sessions.

MAIN OUTCOME MEASURES

The primary outcome measure was the Barthel Activities of Daily Living (BADL) index. The secondary outcome measures included the Nottingham Extended Activities of Daily Living (NEADL) scale, EuroQol-5 Dimensions, ICEpop CAPability measure for Older people, General Self-Efficacy Scale, Falls Efficacy Scale - International (FES-I), Self-Efficacy for Exercise scale, Hospital Anxiety and Depression Scale (HADS) and service use measures. Outcome measures were assessed at baseline and at 3-month follow-up by blinded researchers.

RESULTS

Sixty-two participants were recruited (23% of those who were eligible), 61 were randomised (control, n = 32; intervention, n = 29) and 49 (79%) were followed up at 3 months. Compared with the cohort study, a younger, healthier subpopulation was recruited. There were minimal differences in most outcomes between the two groups, including the BADL index, with an adjusted mean difference of 0.5 (Cohen's d = 0.29). The intervention group showed a medium-sized improvement on the NEADL scale relative to the control group, with an adjusted mean difference between groups of 3.0 (Cohen's d = 0.63). There was a trend for greater improvement in FES-I and HADS in the intervention group, but with small effect sizes, with an adjusted mean difference of 4.2 (Cohen's d = 0.31) and 1.3 (Cohen's d = 0.20), respectively. The cost of delivering the intervention was £231 per patient. There was a possible small relative increase in quality-adjusted life-years in the intervention group. No serious adverse events relating to the intervention were reported.

CONCLUSIONS

Trial methods were feasible in terms of eligibility, recruitment and retention, although recruitment was challenging. The NEADL scale was more responsive than the BADL index, suggesting that the intervention could enable participants to regain better levels of independence compared with usual care. This should be tested in a definitive Phase III RCT. There were two main limitations of the study: the feasibility study lacked power to test for differences between the groups and a ceiling effect was observed in the primary measure.

Increasing Severity of Malnutrition Is Associated With Poorer 30-Day Outcomes in Patients Undergoing Hip Fracture Surgery

OBJECTIVES

Low serum albumin levels (hypoalbuminemia) have classically been used to identify malnutrition. The effect of increasing severity of malnutrition on postoperative outcomes in patients undergoing hip fracture surgery has not been well delineated on a large scale.

DESIGN

Retrospective.

SETTING

Multicenter.

PATIENT/PARTICIPANTS

A total of 12,373 patients undergoing hip fracture surgery from 2006 to 2013 National Surgery Quality Improvement Project data were identified.

INTERVENTION

Patient demographic, comorbidity, and preoperative laboratory data and complication, reoperation, and readmission data were collected.

MAIN OUTCOME MEASUREMENTS

Multivariate logistic regression was used to determine the effect of increasing severity of malnutrition on rates of 30-day postoperative complications, readmissions, and reoperations.

RESULTS

A total of 12,373 hip fractures met inclusion criteria. A total of 6506 (52.6%) patients had normal albumin levels (albumin ≥3.5 g/dL), 3205 (25.9%) patients were mildly malnourished (albumin 3.1-3.49 g/dL), 2265 (18.3%) were moderately malnourished (albumin 2.4-3.1 g/dL), and 397 (3.2%) patients were severely malnourished (albumin <2.4 g/dL). Mean age was similar between the 4 cohorts (P < 0.001). Severe malnutrition was associated with a 2-fold increase in the odds of postoperative complications and mortality when compared with mild malnutrition (P < 0.001). Increasing severity of malnutrition was associated with significantly longer lengths of stay and higher odds of experiencing a related readmission (P < 0.001).

CONCLUSIONS

Increasing severity of hypoalbuminemia is independently associated with poorer outcomes in the 30 days after hip fracture surgery.

How much do combined affective and cognitive impairments worsen rehabilitation outcomes after hip fracture ?

Background

To investigate the association between isolated and combined affective and cognitive impairments with functional outcomes and discharge destination in older patients admitted to rehabilitation after a hip fracture.

Methods

Prospective study in 612 community-dwelling patients aged 65 years and over, admitted to rehabilitation after surgery for hip fracture. Information on socio-demographics, medical, functional, affective, and cognitive status was systematically collected at admission. Functional status, length of stay and destination were assessed at discharge. Functional improvement was defined as any gain on the Barthel Index score between admission and discharge from rehabilitation.

Results

At admission, 8.2% of the patients had isolated affective impairment, 27.5% had cognitive impairment only, and 7.5% had combined impairments. Rate of functional improvement steadily decreased from 91.2% in patients with no cognitive nor affective impairment to 73.8% in those with combined impairments. Compared to patients without any impairment, those with combined impairments had lower odds of functional improvement, even after adjustment for age, gender, health and functional status at admission (adjOR: 0.40; 95%CI: 0.16–1.0; p = .049). The proportion of patients discharged back home gradually decreased from 82.8% among patients without any impairment to only 45.6% in patients with combined impairments. In multivariate analysis, the odds of returning home remained significantly reduced in these latter patients (adjOR: 0.31; 95%CI:0.15–0.66; p = .002).

Conclusions

Affective and cognitive impairments had both independent, and synergistic negative association with functional outcome and discharge destination in patients admitted to rehabilitation after a hip fracture. Nevertheless, patients with combined affective and cognitive impairments still achieved significant functional improvement, even though its magnitude was reduced. Further studies should investigate whether these patients would benefit from better targeted, longer, or more intensive rehabilitation interventions to optimize their functional recovery.

The Influence of Presurgical Factors on the Rehabilitation Outcome of Patients Following Hip Arthroplasty

PURPOSE

The aims of this study were to evaluate the relationship between sociodemographic information, anthropometric values, clinical and presurgery factors, and length of stay (LOS) in older adult patients undergoing total hip arthroplasty (THA) and to predict which factors can delay the start of the rehabilitation program and increase the corresponding LOS.

METHODS

A prospective cohort study was conducted in an orthopedic inpatient unit with 40 patients undergoing THA.

FINDINGS

The Morse Fall Scale scores and pain intensity scores delayed the commencement of the rehabilitation program. Gender and social support were important determinants of LOS and rehabilitation outcome following THA. The weight of the lower limb without osteoarthritis followed by pain intensity and overweight patients also influenced LOS.

CONCLUSIONS/CLINICAL RELEVANCE

Functional outcomes after THA are variable, and the rehabilitation process is an important factor to regain their normal level of physical functioning. This factor can have an impact in the discharge of patients, in resource allocation and in health care of older adult patients.

Development of an evidence-based complex intervention for community rehabilitation of patients with hip fracture using realist review, survey and focus groups

OBJECTIVES

To develop an evidence and theory-based complex intervention for improving outcomes in elderly patients following hip fracture.

DESIGN

Complex-intervention development (Medical Research Council (MRC) framework phase I) using realist literature review, surveys and focus groups of patients and rehabilitation teams.

SETTING

North Wales.

PARTICIPANTS

Surveys of therapy managers (n=13), community and hospital-based physiotherapists (n=129) and occupational therapists (n=68) throughout the UK. Focus groups with patients (n=13), their carers (n=4) and members of the multidisciplinary rehabilitation teams in North Wales (n=13).

RESULTS

The realist review provided understanding of how rehabilitation interventions work in the real-world context and three programme theories were developed: improving patient engagement by tailoring the intervention to individual needs; reducing fear of falling and improving self-efficacy to exercise and perform activities of daily living; and coordination of rehabilitation delivery. The survey provided context about usual rehabilitation practice; focus groups provided data on the experience, acceptability and feasibility of rehabilitation interventions. An intervention to enhance usual rehabilitation was developed to target these theory areas comprising: a physical component consisting of six additional therapy sessions; and a psychological component consisting of a workbook to enhance self-efficacy and a patient-held goal-setting diary for self-monitoring.

CONCLUSIONS

A realist approach may have advantages in the development of evidence-based interventions and can be used in conjunction with other established methods to contribute to the development of potentially more effective interventions. A rehabilitation intervention was developed which can be tested in a future randomised controlled trial (MRC framework phases II and III).

Changes in Basic Movement Ability and Activities of Daily Living After Hip Fractures: Correlation Between Basic Movement Scale and Motor-Functional Independence Measure Scores

OBJECTIVE

The aim of this study was to examine the correlation between basic movement ability and activities of daily living (ADL) in elderly patients after hip fracture surgery and predict ADL outcomes from changes in basic movement ability.

DESIGN

Fifty-four patients receiving rehabilitation after hip fracture surgery were collected prospectively. Ambulatory ability was evaluated using a Basic Movement Scale (BMS), and ADL was evaluated using the motor subscale of the Functional Independence Measure (motor-FIM). From the results of evaluating BMS and motor-FIM weekly, the important postoperative period to regain ADL was investigated.

RESULTS

There was a close correlation between BMS and motor-FIM scores at each evaluation point (r = 0.971, P < 0.001) and a significant correlation between weekly BMS and motor-FIM gains (r = 0.741, P < 0.001). Cluster analysis of BMS scores from postoperative week (POW) 2 to 12 showed three patterns of change, with BMS scores at POW 2 reflecting the outcome.

CONCLUSIONS

The very strong correlation between BMS and motor-FIM scores suggests that BMS is a favorable indicator of changes in ADL. Because basic movement ability at POW 2 also reflected the prognosis, constructive interventions should be implemented early to help patients ambulate and regain other basic movements by no later than POW 2.

Place orientation and visual construction subdomains of the Mini Mental State Examination test as predictors of rehabilitation outcome of post-acute hip-fractured patients

PURPOSE

The study aimed at assessing the relationship between various Mini Mental State Examination (MMSE) subdomains and rehabilitation achievements in post-acute hip-fractured patients.

METHOD

Six hundred and five hip-fractured patients admitted during 2010-2013 to a post-acute geriatric rehabilitation center were included in the study. Main outcome measures were the Functional Independence Measure (FIM) instrument, the motor FIM (mFIM), the Montebello Rehabilitation Factor Score (MRFS) on the mFIM and length of stay (LOS). A logistic regression analysis tested the predictive value of MMSE subdomains for achieving a satisfactory functional gain (mFIM MRFS >30%) on operated patients admitted from community.

RESULTS

Of all the six MMSE subdomains, place orientation and visual construction demonstrated significant predictive values for rehabilitation outcome. Patients who did not err on place orientation and visual construction MMSE domains had better probabilities [(OR 1.28, 95%CI, 1.05-1.58; p = 0.017); (OR 2.15, 95%CI, 1.28-3.59; p = 0.004), respectively] of achieving better rehabilitation achievements. Similar results were obtained for cognitively impaired patient groups [(OR 1.40 95%CI, 1.11-1.77; p = 0.005); (OR 2.47, 95%CI, 1.15-5.30; p = 0.021), respectively]. For the cognitively intact patient group, the variables with significant predictive value were time orientation and visual construction MMSE subdomains [(OR 2.26, 95%CI, 1.18-4.33; p = 0.014); (OR 2.87, 95%CI, 1.16-7.09; p = 0.022), respectively].

CONCLUSIONS

Post-acute hip-fractured patients scoring normally on place orientation and visual construction MMSE subdomains have a better chance of achieving favorable rehabilitation outcome. Implications for Rehabilitation Post-acute hip-fractured patients have a better chance to achieve a favorable rehabilitation outcome when scoring normally on place orientation and visual construction MMSE subdomains. Patients having difficulties in orientation and visual construction may need more rehabilitation time as they lack planning and organizational capacity to follow instructions. Assessing MMSE subdomains may reveal subtle cognitive impairment in patients scored within the normal range on the MMSE test. Identifying subtle cognitive impairment may assist in coordinating the patients and their caregivers' expectations, efficiently allocating resources and help in advanced care planning.

Preoperative Nutritional Status as an Adjunct Predictor of Major Postoperative Complications Following Anterior Cervical Discectomy and Fusion

STUDY DESIGN

Retrospective analysis of the National Surgical Quality Improvement Program (NSQIP), a prospectively collected multicenter surgical outcomes database.

OBJECTIVE

To determine the effect of preoperative nutritional status, as measured by serum albumin concentration, on outcomes following anterior cervical discectomy and fusion (ACDF).

SUMMARY OF BACKGROUND DATA

Nutritional status has been shown to be an important predictor of postoperative recovery and outcomes. Serum albumin concentration is an established marker of overall nutrition and systemic disease, however, its correlation to outcomes following ACDF is unknown.

METHODS

ACDF cases from 2005 to 2010 were identified in the NSQIP and categorized by preoperative serum albumin: normal (≥3.5 g/dL), hypoalbuminemic (<3.5 g/dL), or not measured. Independent demographic and comorbidity variables were assessed, including American Society of Anesthesiologists (ASA) classification. Risk factors for major postoperative complications were identified, including preoperative hypoalbuminemia, and incorporated into a multivariable logistic regression model to determine the strength of preoperative hypoalbuminemia as an adjusted predictor of major postoperative complications.

RESULTS

There were 3671 ACDF cases, of which 1382 (37.6%) had preoperative albumin measurements. Patients with albumin measurements were older and more likely to have higher ASA class, hypertension, and diabetes. Hypoalbuminemic patients had higher rates of having any major postoperative complication(s), specifically pulmonary complications, cardiac complications, and reoperation, relative to those with normal albumin (all P<0.01). These patients also had longer lengths of stay (5.0 vs. 1.9 d). With multivariable regression, preoperative hypoalbuminemia was a strong independent predictor of major postoperative complications, with an adjusted odds ratio of 3.37 (P=0.003).

CONCLUSIONS

In this analysis of a prospective surgical outcomes database, preoperative serum hypoalbuminemia was an important adjunct predictor of major complications following ACDF. In high-risk patients with multiple medical comorbidities, we recommend that clinicians consider nutritional screening and optimization as part of preoperative risk assessment.

Malnutrition: a marker for increased complications, mortality, and length of stay after total shoulder arthroplasty

BACKGROUND

Malnutrition is an established risk factor for postoperative complications. The purpose of this investigation was to determine the overall prevalence of malnutrition in total shoulder arthroplasty (TSA) patients, the differences in prevalence across obesity subgroups, and the overall complication risk of malnourished patients compared with normal patients.

METHODS

The American College of Surgeons National Surgical Quality Improvement Program database was queried for TSA cases from 2005 to 2013 for this retrospective cohort study. Malnutrition was defined as preoperative albumin concentration of <3.5 g/dL. Rates of postoperative complications were compared between normal and malnourished patients.

RESULTS

We identified 4,655 TSA cases, with preoperative albumin measurements available for 1681 patients (36.1%). Propensity score adjustment successfully reduced selection bias, with adjusted P values of >.05 for demographics, body mass index, and modified Charlson Comorbidity Index. Of the cohort with albumin measurements, 7.6% of patients were malnourished according to our criteria. Bivariate analysis showed malnourished patients had higher rates of pulmonary complications, anemia requiring transfusion, extended length of stay (LOS), and death (all P < .05). Propensity-adjusted multivariable logistic regression demonstrated that malnutrition was significantly associated (all P < .05) with postoperative transfusion (odds ratio, 2.49), extended LOS (odds ratio, 1.69), and death (odds ratio, 18.09).

CONCLUSION

The overall prevalence of malnutrition was 7.6%. Malnourished patients were at a significantly increased risk for blood transfusion, longer hospital LOS, and death within 30 days of surgery. Multivariable analysis showed TSA patients with preoperative albumin levels of <3.5 g/dL are at much higher risk for morbidity and death after surgery than patients with albumin levels within normal reference ranges.

Community-Based Hip Fracture Rehabilitation Interventions for Older Adults With Cognitive Impairment: A Systematic Review

BACKGROUND

A hip fracture in older adulthood can result in function and mobility decline. The consequences are debilitating and place a great burden on patients, caregivers, and the health care system. Although inpatient rehabilitation programs have proven effective, the best practices for community-based rehabilitation required to maintain the gains in function and mobility post hospital discharge are currently unknown.

OBJECTIVE

The aim of this systematic review is to identify and evaluate the evidence on the effectiveness of community-based rehabilitation post hospital discharge interventions for older adults with cognitive impairment (CI) following a hip fracture, and to identify the physical recovery outcomes and measures used in previous studies.

METHODS

The methods outlined in the Cochrane Handbook for Systematic Reviews of Intervention were followed and findings were reported using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. The search strategy included a combination of text words and subject headings relating to the concepts of CI, dementia, delirium, cognitive reserve, and hip fractures. For a study to be included in the review, it had to involve participants with CI who underwent hip fracture surgery, and consisted of an outpatient intervention that occurred in the participant's home or community. Peer-reviewed journal articles were identified by searching various databases. Two independent reviewers screened the titles and abstracts to determine which articles comprising of a rehabilitation intervention within a community setting prior to being included for a full article review. A data extraction form and an evidence and quality checklist were used during the full article data analysis and synthesis. A meta-analysis was not conducted due to heterogeneity of measures and outcomes.

RESULTS

The original search resulted in over 3000 articles. Of those, three studies satisfied the necessary criteria to be included in the systematic review. All studies included inpatient and outpatient physiotherapy, with some including a cognitive component, family education, and a discharge assessment.

CONCLUSIONS

The findings from this review suggest that community-based rehabilitation post hospital discharge interventions show promising results towards improving various physical function outcomes, mobility, and activities of daily living for older adults with CI following a hip fracture. This review also demonstrates and discusses the current lack of outpatient rehabilitation interventions targeted towards older adults with CI post-hip fracture. Additionally, several substantive gaps that require attention to move this field forward are highlighted.

Inpatient Rehabilitation Outcomes in a National Sample of Medicare Beneficiaries With Hip Fracture

Effects of patient characteristics on rehabilitation outcomes (functional status at discharge, discharged home) were assessed in a retrospective study of Medicare beneficiaries admitted to Medicare-certified inpatient rehabilitation facilities (IRFs) following hospitalization for hip fracture in 2009 (N = 34,984). Hierarchical regression analysis showed significantly higher functional status at discharge (p < .0001) for patients with these characteristics: White or Asian, younger, female, lived alone, higher functional status at admission, fewer comorbidities, no tier comorbidities, and longer IRF length of stay (LOS). Likelihood of discharged home was higher for patients with these characteristics: Hispanic (1.49 [1.32, 1.68]), Asian (1.35 [1.04, 1.74]), or Black (1.28 [1.12, 1.47]); younger (0.96 [0.96, 0.96]); female (1.14 [1.08, 1.20]); lived with others (2.12 [2.01, 2.23]); higher functional status at admission (1.06 [1.06, 1.06]); fewer comorbidities, no tier comorbidities; and longer LOS (1.61 [1.56, 1.67]). Functional status at admission, tier comorbidities, and race/ethnicity contributed the most to variance in functional status at discharge. Living with others contributed the most to variance in discharged home.

Factors determining eligibility and access to subacute rehabilitation for elderly people with dementia and hip fracture

With hip fracture and dementia increasing in incidence in the global ageing population, there is a need for the development of specific procedures targeting optimal treatment outcomes for these patients. This paper looks primarily at the factors that limit access to subacute rehabilitation services as a growing body of evidence suggests that access to timely inpatient rehabilitation increases functional outcomes for patients both with dementia and without. Information was gathered by searching electronic data bases (SCOPUS, Medline, CINAHL, Health Source Nursing/Academic Addition, Psychinfo and the Cochrane Library) for relevant articles using the search terms dementia OR Alzheimer* AND hip fracture AND subacute rehabilitation OR convalescence for the period 2005–2015. Abstracts were scanned to identify articles discussing eligibility and access. A total of nine papers were identified that directly addressed this topic. Other papers discussing success or failure of rehabilitation and improved models of care were also reviewed. Barriers to access discussed in the literature include information management, management of comorbidities, attitudes, resource availability, and the quality of evidence and education. By identifying these factors we can identify strategic points of intervention across the trajectory of prevention, treatment and rehabilitation that may improve outcomes for this growing group of vulnerable patients. Emerging best practice for these patients is also discussed.

Enhanced rehabilitation and care models for adults with dementia following hip fracture surgery

BACKGROUND

Hip fracture is a major fall-related injury which causes significant problems for individuals, their family and carers. Over 40% of people with hip fracture have dementia or cognitive impairment, and their outcomes after surgery are poorer than those without dementia. It is not clear which care and rehabilitation interventions achieve the best outcomes for these people.

OBJECTIVES

(a) To assess the effectiveness of models of care including enhanced rehabilitation strategies designed specifically for people with dementia following hip fracture surgery compared to usual care.(b) To assess the effectiveness for people with dementia of models of care including enhanced rehabilitation strategies which are designed for all older people, regardless of cognitive status, following hip fracture surgery compared to usual care.

SEARCH METHODS

We searched ALOIS (www.medicine.ox.ac.uk/alois), the Cochrane Dementia and Cognitive Improvement Group Specialised Register, up to and including week 1 June 2014 using the terms hip OR fracture OR surgery OR operation OR femur OR femoral.

SELECTION CRITERIA

We include randomised and quasi-randomised controlled clinical trials (RCTs) evaluating the effectiveness for people with dementia of any model of enhanced care and rehabilitation following hip fracture surgery compared to usual care.

DATA COLLECTION AND ANALYSIS

Two review authors working independently selected studies for inclusion and extracted data. We assessed the risk of bias of included studies. We synthesised data only if we considered studies sufficiently homogeneous in terms of participants, interventions and outcomes. We used the GRADE approach to rate the overall quality of evidence for each outcome.

MAIN RESULTS

We included five trials with a total of 316 participants. Four trials evaluated models of enhanced interdisciplinary rehabilitation and care, two of these for inpatients only and two for inpatients and at home after discharge. All were compared with usual rehabilitation and care in the trial settings. The fifth trial compared outcomes of geriatrician-led care in hospital to conventional care led by the orthopaedic team. All papers analysed subgroups of people with dementia/cognitive impairment from larger RCTs of older people following hip fracture. Trial follow-up periods ranged from acute hospital discharge to 24 months post-discharge.We considered all of the studies to be at high risk of bias in more than one domain. As subgroups of larger studies, the analyses lacked power to detect differences between the intervention groups. Further, there were some important differences in the baseline characteristics of the participants in experimental and control groups. Using the GRADE approach, we downgraded the quality of the evidence for all outcomes to 'low' or 'very low'.No study assessed our primary outcome (cognitive function) nor other important dementia-related outcomes including behaviour and quality of life. The effect estimates for most comparisons were very imprecise, so it was not possible to draw firm conclusions from the data. There was low-quality evidence that enhanced care and rehabilitation in hospital led to lower rates of some complications and that enhanced care provided across hospital and home settings reduced the chance of being in institutional care at three months post-discharge (Odds Ratio (OR) 0.46, 95% confidence interval (CI) 0.22 to 0.95, 2 trials, n = 184), but this effect was more uncertain at 12 months (OR 0.90, 95% CI 0.40 to 2.03, 2 trials, n = 177). The effect of enhanced care and rehabilitation in hospital and at home on functional outcomes was very uncertain because the quality of evidence was very low from one small trial. Results on functional outcomes from other trials were inconclusive. The effect of geriatrician-led compared to orthopaedic-led management on the cumulative incidence of delirium was very uncertain (OR 0.73, 95% CI 0.22 to 2.38, 1 trial, n = 126, very low-quality evidence).

AUTHORS' CONCLUSIONS

There is currently insufficient evidence to draw conclusions about how effective the models of enhanced rehabilitation and care after hip fracture used in these trials are for people with dementia above active usual care. The current evidence base derives from a small number of studies with quality limitations. This should be addressed as a research priority to determine the optimal strategies to improve outcomes for this growing population of patients.

Performance-based outcomes of inpatient rehabilitation facilities treating hip fracture patients in the United States

OBJECTIVE

To examine the influence of facility and aggregate patient characteristics of inpatient rehabilitation facilities (IRFs) on performance-based rehabilitation outcomes in a national sample of IRFs treating Medicare beneficiaries with hip fracture.

DESIGN

Secondary data analysis.

SETTING

U.S. Medicare-certified IRFs (N=983).

PARTICIPANTS

Data included patient records of Medicare beneficiaries (N=34,364) admitted in 2009 for rehabilitation after hip fracture.

INTERVENTION

Not applicable.

MAIN OUTCOME MEASURES

Performance-based outcomes included mean motor function on discharge, mean motor change (mean motor score on discharge minus mean motor score on admission), and percentage discharged to the community.

RESULTS

Higher mean motor function on discharge was explained by aggregate characteristics of patients with hip fracture (lower age [P=.009], lower percentage of blacks [P<.001] and Hispanics [P<.001], higher percentage of women [P=.030], higher motor function on admission [P<.001], longer length of stay [P<.001]) and facility characteristics (freestanding [P<.001], rural [P<.001], for profit [P=.048], smaller IRFs [P=.014]). The findings were similar for motor change, but motor change was also associated with lower mean cognitive function on admission (P=.008). Higher percentage discharged to the community was associated with aggregate patient characteristics (lower age [P<.001], lower percentage of Hispanics [P=.009], higher percentage of patients living with others [P<.001], higher motor function on admission [P<.001]). No facility characteristics were associated with the percentage discharged to the community.

CONCLUSIONS

Performance-based measurement offers health policymakers, administrators, clinicians, and consumers a major opportunity for securing health system improvement by benchmarking or comparing their outcomes with those of other similar facilities. These results might serve as the basis for benchmarking and quality-based reimbursement to IRFs for 1 impairment group: hip fracture.

Inpatient rehabilitation outcomes for patients receiving left ventricular assist device

OBJECTIVE

The aim of this study was to evaluate outcomes of patients participating in inpatient rehabilitation program after left ventricular assist device (LVAD) implantation.

DESIGN

Medical records of 94 patients who received LVADs between January 1, 2008, and June 30, 2010, at the Mayo Clinic in Rochester, MN, were retrospectively reviewed for demographic data, and inpatient rehabilitation functional outcomes were measured by the Functional Independence Measure scale.

RESULTS

After successful implantation of LVAD, the patients were either discharged directly home from acute care (44%) or admitted to inpatient rehabilitation (56%). The patients admitted to inpatient rehabilitation were older than those discharged home. They were also more medically complex and more likely to have the LVAD placed as destination therapy. At discharge, significant improvement occurred in 17 of the 18 activities evaluated by the Functional Independence Measure scale. The mean total Functional Independence Measure scale score at admission was 77.1 compared with a score of 95.2 at discharge (P < 0.0001).

CONCLUSIONS

Approximately half of the patients who received LVAD therapy were admitted in the inpatient rehabilitation. After the implantation of LVAD and inpatient rehabilitation, significant functional improvements were observed. Further studies addressing the role of inpatient rehabilitation for LVAD patients are warranted.

Community-based rehabilitation post hospital discharge interventions for older adults with cognitive impairment following a hip fracture: a systematic review protocol

Background

Hip fractures among older adults remain a public concern. Consequences of a hip fracture include the subsequent decline in function and mobility for the older adult, and an increased burden placed upon their caregivers and the health care system. The consequences may be more challenging if an older adult also has a compromised cognitive reserve. Although rehabilitation programs have proven effective, the best practices and resources required to maintain the gains in function and mobility, to negate diminution of effect, and to enable this patient population to continue living at home are currently unknown.

Objective

The objective of this study is to develop a systematic review protocol focused on identifying the evidence and evaluating the effectiveness of post discharge rehabilitation programs for older adults with a cognitive impairment following a hip fracture.

Methods

The search strategy will include a combination of text words and subject headings relating to the concepts of cognitive impairment, dementia, delirium, cognitive reserve, and hip fractures. Searching various databases will identify peer-reviewed journal articles. There will be two independent reviewers who will screen the titles and abstracts to determine which articles comprise a rehabilitation intervention within a community setting prior to being included for a full article review. A data extraction form and an evidence and quality checklist will be used during the full article data analysis and synthesis. It is expected that there will be a paucity of studies that focus on post discharge rehabilitation interventions for older adults with cognitive impairment following a hip fracture, and few studies that use the same or similar outcome measures. However, if possible, a meta-analysis will be conducted on studies that used similar outcome methods.

Results

This review will synthesize knowledge focusing on activities to maintain and restore function in older adult patients with cognitive impairment once they have completed their active rehabilitation program and return home. A synthesis of the findings will be conducted to determine which components of the interventions identified were the most advantageous to the patient population. The results will be used to develop a multi-faceted post discharge rehabilitation intervention aimed at enabling older adults to return and remain living at home after a hip fracture.

Conclusions

The aim of this systematic review is to generate results that can be used to create interventions that focus on the care necessary to enable older adults to remain living at home post discharge from acute or inpatient rehabilitation care for a hip fracture. With the support and contributions by our associated knowledge users, this systematic review will be used to help inform procedures and policies to facilitate the necessary care and resources required by our patient population.

Site-neutral payment for postacute care: framing the issue

This commentary evaluates the merits of proposals in the United States to create a site-neutral payment system for postacute care for patients with select rehabilitation-related conditions. Under a site-neutral payment system, Medicare would pay providers based on patients' clinical needs, not on the peculiarities of individual postacute settings such as skilled nursing facilities and inpatient rehabilitation facilities. This commentary frames the policy choices by taking into account the research evidence on setting costs and outcomes, the policy tools and preconditions needed for an effective site-neutral payment system, and the overall direction of American health and postacute policy.

Perioperative urinary retention, short-term functional outcome and mortality rates of elderly hip fracture patients

AIM

Perioperative urinary retention (POUR) is common among hip fracture patients. The aim of the present study was to compare the prevalence, risk factors, functional outcomes and survival rates of patients with and without POUR.

METHODS

This was a retrospective chart review study that was carried out in an orthogeriatric hip fracture unit. A total of 639 consecutive hip fracture patients who had hip surgery followed by a standard rehabilitation course participated in the study. Post-void residual volume (PVRV), Functional Independence Measure (FIM) scores (total and motor FIM, FIM gain) and mortality rates (90 and 365 days, end of follow up) were measured.

RESULTS

A total of 328 patients (51.3%) suffered from POUR. Diabetes (OR 1.55, 95% CI 1.04-2.31), urinary infection (OR 3.25, 95% CI 2.16-4.90) and delirium (OR 1.66. 95% CI 1.09-2.52) emerged as the best predictors for POUR. Functional gains were slightly better in patients without POUR (P = 0.037 and P = 0.023, for discharge motor and total FIM gain, respectively). There were no differences in FIM gains at discharge in male patients, whether with or without POUR. However, female patients without POUR showed significantly better motor and total FIM gains on discharge (P = 0.003 and P = 0.003, respectively), compared with females with POUR. In multiple linear regression analyses, POUR in female (but not male) patients was predictive for adverse motor FIM gain (beta = -0.089, P = 0.046). In Cox regression analysis, urinary retention was not associated with mortality rates.

CONCLUSIONS

POUR is highly prevalent in elderly hip fracture patients. It adversely affects the functional outcome of female patients, but is not associated with increased mortality rates.

Trajectories in functional recovery for patients receiving inpatient rehabilitation for unilateral hip or knee replacement

The purpose of this study was to explore trajectories of recovery in patients with lower extremity joint replacements receiving post-acute rehabilitation. A retrospective cohort design was used to examine data from the Uniform Data System for Medical Rehabilitation (UDSMR®) for 7434 patients with total knee replacement (TKR) and 4765 patients with total hip replacement (THR) who received rehabilitation from 2008 to 2010. Functional Independence Measure (FIM)™ instrument ratings were obtained at admission, discharge, and 80-180 days after discharge. Random coefficient regression analyses using linear mixed models were used to estimate mean ratings for items within the four motor subscales (self-care, sphincter control, transfers, and locomotion) and the cognitive domain of the FIM instrument. Mean improvements at discharge for motor items ranged from 1.16 (95% confidence interval [CI]: 1.14, 1.19) to 2.69 (95% CI: 2.66, 2.71) points for sphincter control and locomotion, respectively. At follow-up mean motor improvements ranged from 2.17 (95% CI: 2.15, 2.20) to 4.06 (95% CI: 4.03, 4.06) points for sphincter control and locomotion, respectively. FIM cognition yielded smaller improvements: discharge=0.47 (95% CI: 0.46, 0.48); follow-up=0.83 (95% CI: 0.81, 0.84). Persons who were younger, female, non-Hispanic white, unmarried, with fewer comorbid conditions, and who received a TKR demonstrated slightly higher functional motor ratings. Overall, patients with unilateral knee or hip replacement experienced substantial improvement in motor functioning both during and up to six months following inpatient rehabilitation.

Does early functional outcome predict 1-year mortality in elderly patients with hip fracture?

BACKGROUND

Hip fractures in the elderly are followed by considerable risk of functional decline and mortality.

QUESTIONS/PURPOSES

The purposes of this study were to (1) explore predictive factors of functional level at discharge, (2) evaluate 1-year mortality after hip fracture compared with that of the general population, and (3) evaluate the affect of early functional outcome on 1-year mortality in patients operated on for hip fractures.

METHODS

A total of 228 consecutive patients (average age, 77.6 ± 7.4 years) with hip fractures who met the inclusion criteria were enrolled in an open, prospective, observational cohort study. Functional level at discharge was measured with the motor Functional Independence Measure (FIM) score, which is the most widely accepted functional assessment measure in use in the rehabilitation community. Mortality rates in the study population were calculated in absolute numbers and as the standardized mortality ratio. Multivariate regression analysis was used to explore predictive factors for motor FIM score at discharge and for 1-year mortality adjusted for important baseline variables.

RESULTS

Age, health status, cognitive level, preinjury functional level, and pressure sores after hip fracture surgery were independently related to lower discharge motor FIM scores. At 1-year followup, 57 patients (25%; 43 women and 14 men) had died. The 1-year hip fracture mortality rate compared with that of the general population was 31% in our population versus 7% for men and 23% in our population versus 5% for women 65 years or older. The 1-year standardized mortality rate was 341.3 (95% CI, 162.5-520.1) for men and 301.6 (95% CI, 212.4-391.8) for women, respectively. The all-cause mortality rate observed in this group was higher in all age groups and in both sexes when compared with the all-cause age-adjusted mortality of the general population. Motor FIM score at discharge was the only independent predictor of 1-year mortality after hip fracture.

CONCLUSIONS

Functional level at discharge is the main determinant of long-term mortality in patients with hip fracture. Motor FIM score at discharge is a reliable predictor of mortality and can be recommended for clinical use.

An inpatient rehabilitation model of care targeting patients with cognitive impairment

BACKGROUND

The course and outcomes of hip fracture patients are often complicated by the presence of dementia and delirium, referred to as cognitive impairment (CI), which limits access to in-patient rehabilitation. In response to this concern, members of our team developed and piloted an in-patient rehabilitation model of care (Patient-Centred Rehabilitation Model; PCRM) targeting patients with hip fracture and CI (PCRM-CI). We are now conducting a 3-year study comparing an inpatient rehabilitation model of care for community dwelling individuals with hip fracture and CI (PCRM-CI) to usual care to determine whether it results in improved mobility at the time of discharge from inpatient rehabilitation.

METHODS/DESIGN

A non-equivalent pre-post design is being used to evaluate the PCRM-CI compared to usual care. All community dwelling (private home or retirement home) patients following a hip fracture are eligible to participate. Recruitment of both cohorts is taking place at two facilities. Target accrual is 70 hip fracture patients in the PCRM-CI cohort and 70 patients in the usual care cohort. We are also recruiting 70 health care providers (HCPs), who are being trained to implement the PCRM-CI, and their unit managers. Patient data are collected at baseline, discharge, and 6 months post-discharge from an inpatient rehabilitation program. Evaluations include mobility, physical function, and living arrangement. Additional outcome variables are being collected from medical records and from the patients via their proxies. Data on the prevalence and severity of dementia and delirium are being collected. Staff data are collected at baseline and one year after implementation of the model to determine change in staff knowledge and attitudes toward patients with hip fracture and CI. Bi-monthly semi-structured interviews with unit managers have been conducted to examine factors and barriers influencing the model implementation. Data collection began in 2009 and is expected to be completed in 2012. The control cohort of 70 patients has been recruited, and 45 patients have been accrued to the intervention group to date.

DISCUSSION

Evaluation of this model of care is timely given the increasing proportion of persons with cognitive impairment and hip fractures.

Impact of Vision Impairment on Intensity of Occupational Therapy Utilization and Outcomes in Subacute Rehabilitation

OBJECTIVE. To examine whether vision impairment is a predictor of intensity of occupational therapy utilization and outcomes in a sample of older adults ages ≥55 receiving subacute rehabilitation in a long-term care setting.

METHOD. Data for this cohort study were collected by means of structured, in-person interviews with 100 older adult rehabilitation patients at admission to a subacute unit in a long-term care facility and by medical chart review after discharge.

RESULTS. Regression analyses indicated that after controlling for sociodemographic, health, and social support variables, worse contrast sensitivity was a significant predictor of decreased time in occupational therapy, and worse visual acuity was a significant predictor of higher functional dependency at discharge.

CONCLUSION. Vision impairment may prevent full use of occupational therapy and hinder occupational therapy efficacy in subacute care settings. Study findings underscore the importance of developing low vision rehabilitation interventions that can be delivered in conjunction with more traditional subacute rehabilitation.

Moderate to severe depressive symptoms and rehabilitation outcome in older adults with hip fracture

OBJECTIVE

To evaluate if depressive symptoms affect recovery of walking ability and 1-year institutionalization or mortality in older adults who underwent post-hip fracture (HF) surgery rehabilitation.

METHODS

Depressive symptoms were assessed on admission using the 15-item Geriatric Depression Scale (GDS), with scores ≥10/15 indicating moderate to severe depressive symptoms. Multidimensional assessment included Mini Mental State Examination, Charlson Comorbidity Index, Body Mass Index, albumin serum levels, number of drugs, antidepressants and Barthel Index (BI) on admission and at discharge. Walking ability was evaluated using the BI walking sub-item referred to 1 month before HF, on admission, and at discharge. Patients scoring ≤3/15 BI walking sub-item on admission (i.e. those fully dependent or requiring major supervision in walking) were included. Walking independence at discharge was defined as a score ≥12/15 at the BI walking sub-item.

RESULTS

In multivariate analyses, after adjustment for covariates and potential confounders, patients with moderate to severe depressive symptoms were more likely to fail walking independence at discharge (odds ratio, OR = 3.2; 95% CI = 1.3 to 7.8; p = 0.010) and to be institutionalized or died at 1 year (OR = 3.6, 95% CI = 1.4 to 9.1, p = 0.007). In further analyses, the failure to recover walking independence at discharge partly mediates the relationship between moderate to severe depressive symptoms and 1-year adverse events.

CONCLUSIONS

Moderate to severe depressive symptoms affect the recovery of walking independence after HF rehabilitation and are associated with severe adverse outcomes at 1 year.

Proximal femoral fractures in the elderly: how are we measuring outcome?

INTRODUCTION

Patients with proximal femoral fractures present a difficult problem to health care systems in view of their complex presentations and co-morbidities. Traditionally, the focus of outcome measurement for this patient group has been on mortality and surgical implant success. Increasing recognition of the need to diversify outcome measurements has led to the creation and use of a number of outcome scales. We sought to examine how these scales are being used in the current literature.

METHODS

Abstracts to over 4000 papers related to proximal femoral fracture research were screened to identify commonly used scales in the five main categories of general quality of life measures (QoL), Activities of Daily Living scales (ADL), mobility and physical performance scales, disease-specific scales and hip-specific scales. The 14 identified scales were then searched for directly, and papers analysed for scale usage, timing and interpretation.

RESULTS

ADL scales were the most commonly used group, followed by QoL measures, which are validated for elderly patients. Scale timing and use varied widely between studies. A large number of scales were found in addition to the 14 identified scales. None of the 14 identified scales were validated for the proximal femoral fracture population.

DISCUSSION

A good scale must be appropriate in content, method and clinical utility. Its method of application must be reliable, responsive, and validated for the population in question. Outcome scale usage was difficult to assess in proximal femoral fracture research due to difficulties in isolating the relevant research, and in differences in scale timing and interpretation. Scale prevalence was skewed by use by specific research groups.

CONCLUSION

There is no single unifying scale in widespread use for proximal femoral fracture patients. We would recommend the validation of commonly used scales for this population, and would advise the use of scales from more than one category to assess outcome.

Predictors of outcome following hip fracture rehabilitation

OBJECTIVE

To determine the potential predictors of functional outcome after hip fracture rehabilitation in a large acute inpatient rehabilitation facility.

DESIGN

Retrospective chart review study.

SETTING

Large acute inpatient rehabilitation hospital.

PARTICIPANTS

Patients admitted with a primary admitting diagnosis of hip fracture (n = 753). Patients were excluded if their hip fracture was the result of high-velocity trauma and if their stay was shorter than 48 hours (196 patients).

METHODS

Independent variables included body mass index, gender, ethnicity, smoking history, alcohol consumption, past living situation, past ambulatory status, medical history, prealbumin level, medications that increase the risk of falling, and evidence of prior osteoporosis workup and treatment. These data were entered into a password-encrypted database. Univariate analyses were carried out to evaluate the relationship between independent variables and main outcomes, and multivariate analyses were performed to assess the impact of medical history of diabetes adjusting for other covariates.

MAIN OUTCOME MEASUREMENTS

Discharge location; length of rehabilitation hospital stay (LOS); Functional Independence Measure (FIM) gain, which is calculated as the FIM(discharge) - FIM(admission); and length of stay efficiency (LOSE), which is calculated as the FIM gain divided by the LOS, and measures the rate of FIM change.

RESULTS

Patients with diabetes had a worse LOSE (P = .0008). Multiple linear regression analysis revealed that patients who have a medical history of diabetes have a 0.33 reduction of LOSE compared with other patients. Predictors of better LOSE included younger age (P < .001), fewer medications that predispose to falls (P < .0001), and independent ambulation before fracture (P = .0003).

CONCLUSION

We have found several significant patient characteristics that portend a better functional outcome after hip fracture. These include younger age, female gender, absence of diabetes mellitus, independent prefracture ambulation, not living alone before fracture, and being prescribed fewer medications that predispose to falling during rehabilitation. On the contrary, one of our most interesting findings is that patients with diabetes made slower gains, had a longer LOS and were less likely to be discharged directly home from the acute rehabilitation facility. There are numerous factors that may contribute to this, and suggestions are made for future research.
