Rehabilitation outcomes in patients with full weight-bearing hip fractures

Assessment Tools for the Admission of Older Adults to Inpatient Rehabilitation: A Scoping Review

(1) Objective: To identify the assessment tools and outcome measures used to assess older adults for inpatient rehabilitation. (2) Design: Scoping review. (3) Data sources: ProQuest, PEDro, PubMed, CINAHL Plus with full text (EBSCO), Cochrane Library and reference lists from included studies. (4) Review method: The inclusion of studies covering patients aged >60, focusing on rehabilitation assessments delivered in hospitals in community settings. Studies reporting on rehabilitation specifically designed for older adults-testing for at least one domain that affects rehabilitation or assessments for admission to inpatient rehabilitation-were also included. Results were described both quantitatively and narratively. (5) Results: 1404 articles were identified through selected databases and registers, and these articles underwent a filtering process intended to identify and remove any duplicates. This process reduced the number to 1186 articles. These, in turn, were screened for inclusion criteria, as a result of which 37 articles were included in the final review. The majority of assessments for geriatric rehabilitation were carried out by a multidisciplinary team. Multiple studies considered more than one domain during assessment, with a high percentage evaluating a specific outcome measure used in geriatric rehabilitation. The most common domains assessed were function, cognition and medical status-with communication, vision and pain being the least common. A total of 172 outcome measures were identified in this review, with MMSE, BI, FIM and CCI being the most frequent. (6) Conclusions: This review highlights the lack of standardised approaches in existing assessment processes. Generally, older-adult-rehabilitation assessments struggle to capture rehabilitation potential in a holistic manner. Hence, a predictive model of rehabilitation for assessing patients at the initial stages would be useful in planning a patient-specific programme aimed at maximising functional independence and, thus, quality of life.

Clinical Practice Guideline for Postoperative Rehabilitation in Older Patients With Hip Fractures

OBJECTIVE

The incidence of hip fractures is increasing worldwide with the aging population, causing a challenge to healthcare systems due to the associated morbidities and high risk of mortality. After hip fractures in frail geriatric patients, existing comorbidities worsen and new complications are prone to occur. Comprehensive rehabilitation is essential for promoting physical function recovery and minimizing complications, which can be achieved through a multidisciplinary approach. Recommendations are required to assist healthcare providers in making decisions on rehabilitation post-surgery. Clinical practice guidelines regarding rehabilitation (physical and occupational therapies) and management of comorbidities/complications in the postoperative phase of hip fractures have not been developed. This guideline aimed to provide evidence-based recommendations for various treatment items required for proper recovery after hip fracture surgeries.

METHODS

Reflecting the complex perspectives associated with rehabilitation post-hip surgeries, 15 key questions (KQs) reflecting the complex perspectives associated with post-hip surgery rehabilitation were categorized into four areas: multidisciplinary, rehabilitation, community-care, and comorbidities/complications. Relevant literature from four databases (PubMed, EMBASE, Cochrane Library, and KoreaMed) was searched for articles published up to February 2020. The evidence level and recommended grade were determined according to the grade of recommendation assessment, development, and evaluation method.

RESULTS

A multidisciplinary approach, progressive resistance exercises, and balance training are strongly recommended. Early ambulation, weigh-bearing exercises, activities of daily living training, community-level rehabilitation, management of comorbidities/complication prevention, and nutritional support were also suggested. This multidisciplinary approach reduced the total healthcare cost.

CONCLUSION

This guideline presents comprehensive recommendations for the rehabilitation of adult patients after hip fracture surgery.

Current Concepts in Hip Preservation Surgery: Part II--Rehabilitation

CONTEXT

Successful treatment of nonarthritic hip pain in young athletic individuals remains a challenge. A growing fund of clinical knowledge has paralleled technical innovations that have enabled hip preservation surgeons to address a multitude of structural variations of the proximal femur and acetabulum and concomitant intra-articular joint pathology. Often, a combination of open and arthroscopic techniques are necessary to treat more complex pathomorphologies. Peri- and postoperative recovery after such procedures can pose a substantial challenge to the patient, and a dedicated, thoughtful approach may reduce setbacks, limit morbidity, and help optimize functional outcomes.

EVIDENCE ACQUISITION

PubMed and CINAHL databases were searched to identify relevant scientific and review articles through December 2014 using the search terms hip preservation, labrum, surgical dislocation, femoroacetabular impingement, postoperative rehabilitation, peri-acetabular osteotomy, and rotational osteotomy. Reference lists of included articles were reviewed to locate additional references of interest.

STUDY DESIGN

Clinical review.

LEVEL OF EVIDENCE

Level 4.

RESULTS

Hip preservation procedures and appropriate rehabilitation have allowed individuals to return to a physically active lifestyle.

CONCLUSION

Effective postoperative rehabilitation must consider modifications and precautions specific to the particular surgical techniques used. Proper postoperative rehabilitation after hip preservation surgery may help optimize functional recovery and maximize clinical success and patient satisfaction.

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.

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.

Weight bearing on the affected lower limb in residents of a geriatric rehabilitation hospital

OBJECTIVES

The purpose of the study was to determine whether and to what extent the treatment goal of enhancement of weight bearing on an affected lower limb is achieved in the gait rehabilitation of patients with poststroke hemiparesis, postprosthetic fitting due to unilateral transtibial amputation, or postunilateral hip or knee arthroplasty.

DESIGN

Nonrandomized prepost study. Subjects were 26 residents of a geriatric rehabilitation hospital in the initial stage of gait rehabilitation after poststroke hemiparesis (n = 9), unilateral total hip or knee joint replacement (n = 11), or unilateral transtibial amputation with a fitted prosthesis (n = 6). Weight bearing on the hindfoot and forefoot of the affected limb was measured by using the SmartStep system version 2.2.0, at least once a week, both before and immediately after a gait-training session. Measurements were performed with the patients using their assistive devices.

RESULTS

In the patients with hemiparesis, there was no significant difference found between the initial pretraining maximal weight bearing on the afflicted limb (39% and 50% of body weight on the hindfoot and forefoot, respectively) and that at discharge (47% and 50% of body weight, respectively). In patients after hip or knee arthroplasty and in those who underwent prosthetic fitting, there was a substantial increase found in the loading of the forefoot, but not of the hindfoot, from the initial evaluation to the time of discharge (from 43% to 54% of body weight, P = 0.05, in the arthroplasty group, and from 49.6% to 69.5%, P = 0.09, in the prosthetic group).

CONCLUSIONS

For elderly individuals belonging to the studied diagnostic groups, the goal of enhancing normal weight bearing on the afflicted limb during the time course of 2-3 wks might be unrealistic.

The Impact of Previous Strokes on the Rehabilitation of Elderly Patients Sustaining a Hip Fracture

OBJECTIVE

To evaluate whether a previous stroke may affect the functional outcome gain of elderly patients undergoing rehabilitation for a hip fracture.

DESIGN

A retrospective cohort study.

SETTING

The division of geriatric medicine with rehabilitation wards at a university-affiliated referral hospital.

PARTICIPANTS

Patients with hip fractures (N=460) undergoing a standard rehabilitation course.

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURES

The functional outcome of previous stroke- and nonprevious stroke (NPS)-affected patients assessed by the FIM instrument at admission and discharge from the rehabilitation facility. Data were analyzed by t tests, Pearson correlation, chi-square tests, and linear regression analysis.

RESULTS

Both admission and discharge total FIM scores were significantly higher in NPS compared with previous stroke patients (63.53+/-19.89 vs 52.19+/-19.37, P<.001) and (84.23+/-24.93 vs 71.37+/-25.03, P=.001), respectively. However, changes in total FIM (20.70+/-11.68 vs 19.17+/-13.32, P=.38) and in motor FIM (19.84+/-10.63 vs 17.96+/-11.21, P=.23) at discharge were not statistically significant between the 2 groups. A linear regression analysis showed that a previous stroke was not predictive of a worse total FIM gain at discharge (P=.58).

CONCLUSIONS

NPS hip fracture elderly patients show higher admission and discharge FIM scores compared with previous stroke patients. Nevertheless, both groups achieve similar FIM gains during rehabilitation period. A previous stroke should not be considered as adversely affecting the rehabilitation of such patients.

Admission albumin levels and functional outcome of elderly hip fracture patients: is it that important?

BACKGROUND AND AIMS

Low serum albumin level is considered a marker of poor health outcome in various medical conditions. A relationship between low albumin levels and poor functional outcome has been found in the elderly, lower albumin predicting a greater functional decline. The objective of this study was to evaluate to what extent admission albumin levels may affect the functional outcome of elderly hip fracture patients.

METHODS

This retrospective chart review study was conducted in an orthogeriatric unit of a university-affiliated referral hospital. The participants were 449 elderly patients with hip fractures, admitted for a standard rehabilitation course. Functional outcome of patients with normo-albuminemia and hypo-albuminemia was assessed by Functional Independence Measurement (FIM) at admission and discharge. Data were analyzed by t-test, Pearson's correlation, Chi-square test and Linear Regression.

RESULTS

38.8% of patients were hypoalbuminemic upon admission. These patients were older (p<0.001) and had lower Mini-Mental State Examination (MMSE) scores (p=0.003), compared with normo- albuminemic patients. Discharge FIM scores were higher in normo-albuminemic compared with hypo-albuminemic patients (total FIM 86.1+/-23.9 and 77.0+/-26.4, respectively; p<0.001; motor-FIM 60.0+/-16.3 and 53.4+/-18.0, respectively; p<0.001). Linear regression analysis showed that total FIM at discharge was inversely associated with pre-fracture function (beta -0.13; p<0.001). A high MMSE score (beta 0.16; p<0.001), female gender (beta 0.05; p=0.02) and higher admission total FIM scores (beta 0.69; p<0.001) emerged as predictors of higher total FIM scores upon discharge. Albumin levels did not independently predict better total FIM scores upon discharge (beta -0.02; p=0.36).

CONCLUSIONS

Normo-albuminemic patients present with better admission FIM scores and have higher discharge FIM scores. After controlling for possible confounders, albumin remains a non-significant predictor of higher discharge FIM scores. We suggest that low albumin levels should not be considered as adversely affecting the rehabilitation of elderly hip fracture patients.

Pattern of functional change during rehabilitation of patients with hip fracture

OBJECTIVE

To examine the rate of functional change in 2 domains, activities of daily living (ADLs) and mobility, over 2 time periods during hip fracture rehabilitation.

DESIGN

Retrospective analysis of data contained in an administrative dataset.

SETTING

Seventy skilled nursing facilities (SNFs).

PARTICIPANTS

People (N=351) receiving rehabilitation in SNFs from March 1998 to February 2003 after hip fractures.

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURE

Rate of change in scores in the ADL and mobility domains of the FIM instrument during 2 time intervals of rehabilitation.

RESULTS

The rate of functional change across 2 time intervals was constant for mobility (mean change in FIM points per day, .46 vs .49), but declined in the second time period for ADLs (mean change in FIM points per day, .55 vs .41). Executive function, length of stay (LOS), and medical complexity were related to rate of change in mobility, and baseline ADLs, executive function, living setting, and LOS were related to rate of change in ADLs. There was an interaction between rehabilitation phase and baseline mobility. People with lower baseline mobility had an increased rate of change during the second interval (mean change in FIM points per day, .41 vs .55), whereas those with higher baseline mobility had a decreased rate of change (mean change in FIM points per day, .50 vs .43).

CONCLUSIONS

The pattern of functional change over time differed for ADL and mobility domains, and for specific groups of patients. The results have implications for goal setting and discharge planning.

Development of a conceptual framework for the assessment of geriatric rehabilitation outcomes

The objective of the study was to develop a conceptual framework of key assessment areas for the evaluation of rehabilitation outcomes in older persons. The study was designed in four stages. First, a review of the literature generated a list of 84 potential outcome variables. Second, semi-structured interviews were conducted with older adults informants (n = 19) to record their thoughts about important rehabilitation outcomes. From the analyses of the transcripts, 20 recurrent themes became apparent. Third, relevant assessment areas were determined based on the merged data from the literature and the interviews. Fourth, a focus group was held with a panel of eight interdisciplinary experts with strong involvement in geriatric rehabilitation to evaluate, improve, and validate the preliminary work. As a result of the study, the conceptual framework for the assessment of geriatric rehabilitation outcomes (FAGRO) is composed of four primary outcome domains related to important activities for community-living older persons: mobility activities, basic activities of daily living, activities of independent living, and leisure activities. The models also allows for four brief evaluations of underlying functioning components, including: physical functioning, psychological functioning, social functioning, and factors related to the caregiver status and available resources. The model has the potential to become a valuable additional tool for outcome assessment, researched and developed specifically for geriatric rehabilitation.
