Maximum Tolerated Dose of Walking for Community-Dwelling People Recovering From Hip Fracture: A Dose-Response Trial

A walking programme for adults living in the community after hip fracture: A feasibility randomized controlled trial

OBJECTIVE

To test the feasibility of a walking programme for community-dwelling adults recovering from hip fracture.

DESIGN

A randomized controlled trial with embedded qualitative analysis.

SETTING

Community.

PARTICIPANTS

Aged at least 60 years and living in the community after hip fracture.

INTERVENTIONS

In addition to standard care, the experimental group received weekly home-based physiotherapy for 12 weeks to facilitate 100 minutes/week of moderate-intensity walking.

MAIN OUTCOME MEASURES

Feasibility domains of demand, acceptability, implementation, practicality and limited efficacy.

RESULTS

Of 158 potentially eligible, 38 participated (23 women, mean age 80 years, SD 9). The recruitment rate of 24% indicated low demand. Participants considered the walking programme highly acceptable. The programme was implemented as intended; the experimental group received a mean of 11 (SD 1) consultations and averaged more than 100 min of walking per week. The programme was practical with no serious adverse events and no between-group difference in risk of falling or hospital readmissions. Demonstrating evidence of efficacy, there were moderate standardized mean differences for physical activity favouring the experimental group, who increased daily moderate-intensity physical activity compared to the control group (MD 8 min, 95% CI 2-13). There were no between-group differences in mobility, walking confidence or quality of life.

CONCLUSION

A walking programme for community-dwelling older adults after hip fracture was acceptable, could be implemented as intended and was practical and demonstrated preliminary evidence of efficacy in increasing physical activity. However, low demand would threaten the feasibility of such a programme.

Community Reintegration After Rehabilitation for Hip Fracture: A Systematic Review and Meta-analysis

OBJECTIVE

To investigate the effect of rehabilitation on the physical, social, and psychological dimensions of community reintegration after hip fracture.

DATA SOURCES

Electronic databases Embase, EMCare, MEDLINE, PsycINFO, Cumulative Index to Nursing and Allied Health, and SPORTDiscus were searched from the earliest date available to second June 2021.

STUDY SELECTION

Searching identified 1844 potentially relevant articles. Twenty randomized controlled trials evaluating physical retraining, cognitive retraining, and model of care interventions on physical, social and psychological aspects of community reintegration for 3075 adults after hip fracture were included.

DATA EXTRACTION

Data were extracted using predetermined templates for participant characteristics, intervention type and setting, and outcomes related to community reintegration. Methodological quality was assessed using the Physiotherapy Evidence Database scale, and the Grading of Recommendations, Assessment, Development, and Evaluations approach was applied to each meta-analysis.

DATA SYNTHESIS

Post intervention data were pooled to calculate risk ratios (RRs), mean differences, standardized mean differences, and 95% confidence intervals (CIs) using inverse variance methods and a random-effects model. Compared with usual care or no rehabilitation, there was moderate-quality evidence to suggest that physical retraining interventions improved outdoor mobility (RR, 1.45; 95% CI, 1.09-1.91; I2=0%) and moderate-quality evidence to suggest that physical retraining improved Nottingham Extended Activities of Daily Living Scale scores (physical and social reintegration) by a mean 3.5 units (95% CI, 0.99-6.01; I2=0%). Meta-analyses showed no significant effect for cognitive retraining and model of care interventions on any dimension of community reintegration.

CONCLUSIONS

Preliminary evidence suggests that physical rehabilitation after hip fracture improves physical and social aspects of community reintegration. The effect of psychological and home-based interventions on community reintegration is currently unclear. Further research is needed to determine the effect of rehabilitation on community reintegration, using interventions and measures that encompass all dimensions of community reintegration.

Functional status of community-dwelling older adults after inpatient rehabilitation

Background/aims:

Factors that influence functional ability in older adults after rehabilitation are not well understood. The aim of this study was to investigate how older people function in their community after being discharged from inpatient rehabilitation.

Methods

A cross-sectional study was undertaken of community-dwelling older adults (n=86, 75 ± 6 years) discharged from rehabilitation in the previous 12 months. Basic functional independence was assessed using the Functional Independence Measure and complex functional independence was assessed using the Frenchay Activities Index. Multiple regression analyses were conducted to assess any association between predetermined factors and function.

Results

Functional Independence Measure scores and physical activity levels after being discharged accounted for 50% of the variance in basic function (R2=0.50, F=40.75, P<0.001). Frenchay Activities Index scores, physical activity, age, sex and migrant status accounted for 68% of variance in complex function (R2=0.68, F=29.75, P<0.001).

Conclusions

Clinicians are encouraged to implement strategies to improve function at discharge from rehabilitation and to promote physical activity among older people at risk of poor function following rehabilitation.

Motivational interviewing with community-dwelling older adults after hip fracture (MIHip): protocol for a randomised controlled trial

INTRODUCTION

Community-dwelling people recovering from hip fracture have the physical capacity to walk in their community but lack the confidence to do so. The primary aim of this trial is to determine whether motivational interviewing increases time spent walking at 12 months in community-dwelling people after hip fracture compared with an attention placebo control group. Secondary aims are to evaluate cost effectiveness, patient and health service outcomes and to complete a process evaluation.

METHODS AND ANALYSIS

An assessor-blinded parallel group randomised controlled design with embedded health economic evaluation and process evaluation will compare the effects of n=270 participants randomly allocated to an experimental group (motivational interviewing) or a control group (dietary advice). For inclusion, participants are aged ≥65 years, living at home independently within 6 months of discharge from hospital after hip fracture and able to walk independently and communicate with conversational English. Key exclusion criteria are severe depression or anxiety, impaired intellectual functioning and being medically unstable to walk. Participants allocated to the experimental group will receive 10 (8 weekly and 2 booster) telephone-based sessions of motivational interviewing to increase walking over 16 weeks. Participants allocated to the control group will receive an equivalent dose of telephone-based dietary advice. The primary outcome is daily time spent walking over 7 days assessed at weeks 0, 9, 26 and 52. Secondary outcomes include measures of psychological-related function, mobility-related function, community participation, health-related quality of life and falls. Health service utilisation and associated costs will be assessed. Process evaluation will assess the fidelity of the motivational interviewing intervention and explore contextual factors through semistructured interviews.

ETHICS AND DISSEMINATION

Ethical approval obtained from Eastern Health (E19-002), Peninsula Health (50261/EH-2019), Alfred Health (617/20) and La Trobe University (E19/002/50261). The findings will be disseminated in peer-reviewed journals, conference presentations and public seminars.

Cognitive Impairment Level and Elderly Hip Fracture: Implications in Rehabilitation Nursing

PURPOSE

The aim of the study was to determine the cognitive impairment level influence in descriptive characteristics, comorbidities, complications, and pharmacological features of older adults with hip fracture.

DESIGN

Cross-sectional study.

METHOD

Five hundred fifty-seven older adults with hip fracture were recruited and divided into cognitive impairment levels (severe/moderate, mild, no impairment). Descriptive characteristics, comorbidities, complications, and pharmacological data were collected.

FINDINGS

Significant differences (p < .05, R = .012-.475) between cognitive impairment levels were shown. Shorter presurgery hospital length of stay and lower depression and Parkinson comorbidities; delirium complication; and antidepressants, antiparkinsonians, and neuroleptics use were shown for the no-impairment group. With regard to the cognitive impairment groups, lower presence of cardiopathy and hypertension; higher presence of dementia; antihypertensives, antiplatelets, and antidementia medication; infection/respiratory insufficiency complications; and lower constipation complications were shown.

CONCLUSION

Cognitive impairment levels may determine the characteristics, comorbidities, pharmacology, and complications of older adults with hip fracture.

CLINICAL RELEVANCE

Cognitive impairment level may impact rehabilitation nursing practice, education, and care coordination.

Three short sessions of physiotherapy during rehabilitation after hip fracture were no more effective in improving mobility than a single longer session: a randomised controlled trial

OBJECTIVES

To determine if three short daily sessions of physiotherapy for rehabilitation inpatients after hip fracture is more effective than providing one long daily session in improving mobility.

DESIGN

A single-blinded randomised controlled trial.

SETTING

Two inpatient rehabilitation wards at a hospital in Melbourne, Australia.

PARTICIPANTS

Seventy-six rehabilitation inpatients after hip fracture. The key exclusion criterion was not being allowed to weight bear.

INTERVENTIONS

All participants received multidisciplinary rehabilitation. Experimental participants received three 15-minute sessions of physiotherapy 5 days per week until discharge. Control participants received one 45-minute session of physiotherapy 5 days per week until discharge.

MAIN OUTCOME MEASURES

The primary outcome, mobility, was assessed with the de Morton Mobility Index 2 weeks after admission and at discharge. Secondary outcomes were Functional Independence Measure mobility (transfers, ambulation, steps), physical activity measured with an accelerometer, length of stay, discharge destination, readmissions within 30 days of discharge, and patient and physiotherapist satisfaction.

RESULTS

Sixty-seven (88%) participants completed mobility assessment at discharge and 34 (45%) at 2 weeks. There were a greater proportion of missed sessions in the experimental group (84% adherence vs 95%). There was no between-group difference in mobility at discharge (MD -1.9 points, 95%CI-6.9 to 3.2) or at 2 weeks (MD -3.5 points, 95%CI-15.4 to 8.4). There were no between-group differences in any secondary outcomes.

CONCLUSIONS

Providing inpatient physiotherapy rehabilitation in three shorter sessions resulted in more missed sessions and likely did not improve mobility outcomes compared with providing one longer session for patients recovering from hip fracture.

Exercise prescription dose for castrate-resistant prostate cancer patients: a phase I prescription dose escalation trial

PURPOSE

To determine the start exercise prescription dose in metastatic castrate-resistant prostate cancer (mCRPC) patients receiving second-line hormone treatment and recommended phase II exercise prescription.

METHODS

Patients were enrolled in a 3 + 3 dose escalation phase I trial of aerobic, resistance, and flexibility exercises to evaluate dose-limiting tolerance and safety. Tolerance was defined as Borg score ≤ 16 and safety (pain) as a visual analogue scale score (VAS) ≤ 3 and CTCAE grade < 2. Dose level 1 (escalation start dose) was set at 15 min. Aerobic training (50-80% HRmax warm-up and cooling-down; and 65-80% HRmax. core), 1 set with 8-10 repetitions (reps.) resistance training (50-60% 1-RM, 8 exercises), and 1 set (30s) with 2 reps flexibility training (5 exercises). The prescription dose escalation was designed in four levels (from dose -1 to 3), with a dose escalation in volume and intensity of the exercises.

RESULTS

Nine patients were included in two dosing cohorts and were under active treatment (n = 4 abiraterone acetate and n = 5 enzalutamide). Dose limiting safety concerns were observed in 2 out of 3 patients in dose level 2 and 1 patient out of 6 in dose level 1 due to VAS > 3 during resistance training and/or flexibility training. No tolerance issues were observed in the two dosing cohorts. The optimal start exercise prescription dose was set at dose level 1 due to safety issues at dose level 2.

CONCLUSION

Our findings suggest that exercise is perceived tolerable in mCRPC patients receiving second-line hormone therapy. Caution is indicated on safety during performance of the exercises.

Community-based rehabilitation for physically impaired earthquake victims: An evidence-based practice protocol and its pre-post experimental study

BACKGROUND

A natural disaster like earthquake is a sudden event that causes not only the loss of life but also mental, emotional, and physical disabilities. An earthquake of 7.8 magnitudes hit Nepal and injured more than 18,500 people in 2015. There was a critical need to develop rehabilitation protocols. Therefore, we aimed to structure community-based rehabilitation protocols for physically impaired earthquake victims and to investigate immediate effect of the intervention to address disability and reduce public health burden.

MATERIALS AND METHODS

Evidence-based rehabilitation protocols for various injuries were structured to address the victims' impairments and activity limitations. The protocols were administered to 13 victims of one of the most affected community sites, for 60 min/day, 12 days in 2 weeks at their own doors. Local resources were used to make the protocols sustainable. An immediate effect of the protocols was evaluated within the group. The World Health Organization Disability Assessment Schedule, numerical pain rating scale, and time up and go (TUG) test were used to measure disability level, pain, and mobility status, respectively. Wilcoxon's signed rank test was used to analyze pre-post data.

RESULTS

All participants completed the rehabilitation without adverse effects. The treatment demonstrated significant reduction in disability level (P < 0.001, effect size = 0.63) and pain level (P = 0.007). However, change with TUG was not significant.

CONCLUSION

The evidence-based, structured community rehabilitation protocols demonstrated benefits in improving the victim's quality of life. Follow-ups will be continued to explore sustainability and long-term effects of the interventions.

Functionality, comorbidity, complication & surgery of hip fracture in older adults by age distribution

BACKGROUND

Hip fractures may be the greatest complication secondary to osteoporotic disorder. The objective of this study was to determine the influence of age distribution in the functionality, comorbidity, complications and surgical features of older adults with hip fractures.

METHODS

A prospective cohort study was carried out from 2013 to 2014. A sample of 557 adults over 75 years old with osteoporotic hip fractures was recruited from the Orthogeriatric Unit of the León University Hospital (Spain). Age distributions of 75-84, 85-90 and >90 years old were considered. Firstly, sociodemographic data, fracture type and hospital staying days were collected. Secondly, baseline functionality (Barthel index), ambulation, cognitive impairment and comorbidities were described. Thirdly, surgical intervention, urgency, type, American Association of Anesthesiologists (ASA) scores, non-surgical cause, and baseline pharmacologic treatments were determined. Finally, complications and features at hospital discharge were observed.

RESULTS

The age ranges did not show any statistically-significant differences (P<.05; R2=.000-.005) for gender, fracture type, or number of hospital staying days. Statistically-significant differences (P<.05; R2=.011-.247) between age groups were observed for Barthel index, cognitive impairment, dementia, osteoporosis, Parkinson's disease, aortic stenosis, surgery type, ASA-score, non-surgical cause, benzodiazepines, antidementia, anti-osteoporosis, insulin, pharmacologic treatments, renal function alteration, heart failure, destination and ambulation features. All other measurements did not show statistically-significant differences (P>.05; R2=.000-.010).

CONCLUSION

Age distributions greater than 75 years old may determine the functionality, comorbidities, surgical features, baseline pharmacologic treatments, complications and features at hospital discharge for older adults who suffer a hip fracture.

The impact of body composition, pain and resilience on physical activity, physical function and physical performance at 2 months post hip fracture

The purpose of this study was to test a model of the factors influencing physical activity, physical function and physical performance at 2 months post hip fracture and compare model fit between men and women. Age, cognitive status, comorbidities, pain, resilience, bone mineral density, total body lean mass, total body fat and grip strength were hypothesized to be directly and/or indirectly related to physical activity, physical function and physical performance. This analysis used data from the seventh Baltimore Hip Studies (BHS-7), a prospective cohort study that included 258 community-dwelling participants, 125 (48%) men and 133 (52%) women, hospitalized for treatment of a hip fracture; survey and objective data were obtained at 2 months post hip fracture. In addition to age, sex and comorbidities (modified Charlson scale), data collection included body composition from dual-energy x-ray absorptiometry (DXA) scans, grip strength, and physical activity, function and performance based on the Yale Physical Activity Survey, the Short Physical Performance Battery and the Lower Extremity Gain Scale. Age, cognition, and comorbidities were not significantly associated with resilience; and, resilience was not associated with pain. In addition, bone mineral density was not associated with physical activity, physical performance or physical function. Total lean body mass, resilience and pain were associated with physical activity, physical function and physical performance in women, but were not consistently associated with physical and functional outcomes in men. Future research should consider evaluation of muscle quality and additional psychosocial factors (e.g., depression, social supports) in model testing.
