The influence of hospital and home environments on physical activity and sedentary behaviour: Perceptions of people recovering from fractures

BACKGROUND

A lack of evidence exists contrasting the factors that influence physical activity and sedentary behaviour in both hospital and home settings before and after discharge from acute hospitalisation for fractures.

OBJECTIVE

To describe and compare perceptions of environmental influences on physical activity in hospital and home settings in people recovering from fractures.

METHOD

Semi-structured interviews were conducted with patients hospitalised following fractures (hip fracture or multi-trauma), exploring the barriers and enablers to physical activity within hospital and home settings. Interviews were conducted within two weeks of hospital discharge, audio recorded and transcribed prior to thematic analysis via a framework approach.

RESULTS

Between December 2022 and May 2023, 12 semi-structured interviews were undertaken with an equal number of participants who sustained an isolated hip fracture or multi-trauma. The median (IQR) age of participants was 60 (52-68) years, with half being male, and the majority sustaining their injuries via transport crashes. Three main themes that influenced physical activity behaviours in hospital and home settings were: having the opportunity, having a reason, and having support and assistance to be active.

CONCLUSION

During the period of reduced physical capability following fracture, patients need to be provided with opportunities and motivation to be active, particularly within the hospital setting. Findings from this study will assist clinicians to better support people recovering from fractures via greater engagement in physical activity within hospital and home settings.

HIP fracture Supplemental Therapy to Enhance Recovery (HIPSTER): a protocol for a randomised controlled trial

INTRODUCTION

Hip fractures result in substantial health impacts for patients and costs to health systems. Many patients require prolonged hospital stays and up to 60% do not regain their prefracture level of mobility within 1 year. Physical rehabilitation plays a key role in regaining physical function and independence; however, there are no recommendations regarding the optimal intensity. This study aims to compare the clinical efficacy and cost-effectiveness of early intensive in-hospital physiotherapy compared with usual care in patients who have had surgery following a hip fracture.

METHODS AND ANALYSIS

This two-arm randomised, controlled, assessor-blinded trial will recruit 620 participants who have had surgery following a hip fracture from eight hospitals. Participants will be randomised 1:1 to receive usual care (physiotherapy according to usual practice at the site) or intensive physiotherapy in the hospital over the first 7 days following surgery (two additional sessions per day, one delivered by a physiotherapist and the other by an allied health assistant). The primary outcome is the total hospital length of stay, measured from the date of hospital admission to the date of hospital discharge, including both acute and subacute hospital days. Secondary outcomes are functional mobility, health-related quality of life, concerns about falling, discharge destination, proportion of patients remaining in hospital at 30 days, return to preadmission mobility and residence at 120 days and adverse events. Twelve months of follow-up will capture data on healthcare utilisation. A cost-effectiveness evaluation will be undertaken, and a process evaluation will document barriers and facilitators to implementation.

ETHICS AND DISSEMINATION

The Alfred Hospital Ethics Committee has approved this protocol. The trial findings will be published in peer-reviewed journals, submitted for presentation at conferences and disseminated to patients and carers.

Validity of the activPAL and ActiGraph for measuring sitting time and steps in hospitalised orthopaedic patients with altered weight bearing

PURPOSE

To determine the criterion validity of the activPAL and ActiGraph for measuring steps and sitting/sedentary time, compared to observation, in people hospitalised following orthopaedic lower limb injury who were weight bearing (WB) (i.e., walking) or non-weight bearing (NWB) (i.e., hopping).

MATERIALS AND METHODS

Participants wore an activPAL and ActiGraph on the hip/thigh/unaffected (UA)/affected ankle (AA) while completing bouts of walking and sitting. Lin's concordance correlation coefficient, Bland-Altman methods, and ratio of agreement were used to compare device-measured to observed (videoed) step count, sitting/sedentary time.

RESULTS

In 42 participants, the ActiGraph demonstrated excellent concordance with the observed step count when worn on the ankle (LCC 0.91-0.92) compared to the hip (LCC 0.56) in participants that were WB. The ActiGraph AA achieved the highest concordance (LCC 0.71) with observed steps in participants NWB. The activPAL had poor concordance with observed steps, particularly at slow gait speeds, in participants that were WB (LCC 0.38-0.46), however was less influenced by gait speed and had good concordance in NWB participants (LCC 0.52-0.69). The activPAL (LCC 0.79-0.88) and ActiGraph UA (LCC 0.94) showed excellent concordance with observed sitting and sedentary time, respectively.

CONCLUSIONS

The ActiGraph worn at the ankle provided the most valid measure of steps in people who are WB and NWB following orthopaedic injury, while the activPAL was best for measuring sitting time.Implications for rehabilitationTo accurately measure both steps and sitting time in people with lower limb orthopaedic injuries, a combination of activity monitors should be used (i.e., ActiGraph for steps, activPAL for sitting time).The ActiGraph device when worn on the ankle demonstrated the strongest agreement with observed step count in people who were weight bearing and non-weight bearing.Caution is needed when using thigh- or hip-worn devices in people who walk slowly.

Perceptions of an Interactive Trauma Recovery Information Booklet

BACKGROUND

Previous research has shown that people with traumatic injuries have unmet information needs with respect to their injuries, management, and recovery. An interactive trauma recovery information booklet was developed and implemented to address these information needs at a major trauma center in Victoria, Australia.

OBJECTIVE

The aim of this quality improvement project was to explore patient and clinician perceptions of a recovery information booklet introduced into a trauma ward.

METHODS

Semistructured interviews with trauma patients, family members, and health professionals were undertaken and thematically analyzed using a framework approach. In total, 34 patients, 10 family members, and 26 health professionals were interviewed.

RESULTS

Overall, the booklet was well accepted by most participants and was perceived to contain useful information. The design, content, pictures, and readability were all positively appraised. Many participants used the booklet to record personalized information and to ask health professionals questions about their injuries and management.

CONCLUSION

Our findings highlight the usefulness and acceptability of a low-cost interactive booklet intervention to facilitate the provision of quality of information and patient-health professional interactions on a trauma ward.

Measurement of Mobility and Physical Function in Patients Hospitalized With Hip Fracture: A Systematic Review of Instruments and Their Measurement Properties

OBJECTIVE

Hip fractures are common and significantly impact mobility and physical function. Measurement of patient progress post hip fracture in the acute hospital setting is important to monitor early recovery and outcomes. The objective of this systematic review was to assess the measurement properties (reliability, validity, responsiveness), interpretability, and clinical utility of instruments used to measure mobility and physical function in patients with hip fracture in the acute hospital setting.

METHODS

Three databases (MEDLINE, Embase, and CINAHL) were searched. Studies reporting direct clinician assessment instruments to measure mobility or physical function in patients with hip fracture were included. Data were extracted by 2 reviewers, and the quality of each study was determined using the COnsensus-based Standards for the selection of health Measurement INstruments risk of bias checklist.

RESULTS

Sixty-eight studies were included with 19 measurement instruments identified. The most frequently used instruments were the Timed "Up & Go" Test (TUG) (19 studies), Barthel Index (BI) (18 studies), Cumulated Ambulation Score (CAS) (18 studies), and Functional Independence Measure (FIM) (14 studies). All 4 of these instruments demonstrated good predictive validity (clinical outcomes and mortality) and responsiveness over time (effect sizes 0.63-2.79). The BI and CAS also had good reliability (intraclass correlation coefficient [ICC] >0.70). Floor effects were demonstrated for the TUG, CAS, and FIM (16%-60% of patients). The TUG, CAS, and BI all had good clinical utility.

CONCLUSION

Depending on the context (use by treating clinicians, research, benchmarking), 1 or a combination of the BI, CAS, and TUG provide robust measurement of mobility and physical function for patients with hip fracture in the acute hospital setting.

IMPACT

This study identified 3 instruments suitable for measuring mobility and physical function in hospitalized patients following hip fracture. This provides clinicians with tools to measure patient progress and benchmark across sites to improve patient outcomes.

Outcomes after application of halothoracic orthosis for cervical spine trauma

BACKGROUND

Cervical spine fractures can be managed operatively or nonoperatively, considering injury type and patient factors. Nonoperative management may include application of a halothoracic orthosis (HTO). The aim of our study was to describe our patients managed with HTO, review their 6-month and 12-month outcomes, and identify associated factors.

METHODS

Patients fitted with an HTO at our institution in 2014 were included. Data collected included patient demographics, hospital-related data, and radiological union. Injury detail and 6-month and 12-month patient-reported outcomes (Glasgow Outcomes Scale Extended and return to work [RTW]) were accessed through Victorian Orthopedic Trauma Outcomes Registry. Factors related to these outcomes were included in a mixed-effect regression model for each outcome.

RESULTS

Eighty-six patients (median age 46.5 years) of whom 52 (60%) were male individuals were included. Two-thirds (57 patients) were road trauma patients, and 58 patients (67%) experienced an isolated injury. Thirty-seven patients (43%) experienced a C2 fracture and 27 (31%) experienced a facet fracture. Twelve-month follow-up was completed for 78 patients (91%) with 27 (35%) reporting a good recovery, and 65% (31/48) patients returned to work. Factors associated with lower odds of RTW included compensation, a facet joint fracture, and experiencing comorbidities. No factors were significantly associated with functional outcome, although female individuals exhibited a slower recovery trajectory than male individuals.

CONCLUSION

Many patients reported poor 12-month outcomes after HTO for traumatic injury. Factors associated with worse outcomes should be considered when deciding on management of patients with cervical spine fractures.

Reliability, Validity, Clinical Utility, and Responsiveness of Measures for Assessing Mobility and Physical Function in Patients With Traumatic Injury in the Acute Care Hospital Setting: A Prospective Study

OBJECTIVE

The longer-term impact of injury is increasingly recognized, but the early phases of recovery are less well understood. The best tools to measure early recovery of mobility and physical function following traumatic injury are unclear. The purpose of this study was to assess the clinical utility, validity, reliability, and responsiveness of 4 mobility and physical function measures in patients following traumatic injury.

METHODS

In this cohort, measurement-focused study (n = 100), the modified Iowa Level of Assistance Score, Acute Care Index of Function, Activity Measure for Post-Acute Care "6 Clicks" short forms, and Functional Independence Measure were completed during first and last physical therapy sessions. Clinical utility and floor and ceiling effects were documented. Known-groups validity (early vs late in admission and by discharge destination), predictive validity (using 6-month postinjury outcomes data), and responsiveness were established. Interrater reliability was assessed in 30 patients with stable mobility and function.

RESULTS

Participants had a median age of 52 years (interquartile range = 33-68 years), and 68% were male. The modified Iowa Level of Assistance Score, Acute Care Index of Function, and "6 Clicks" short forms were quick to administer (an extra median time of 30 seconds-1 minute), but the Functional Independence Measure took much longer (extra median time of 5 minutes). At the last physical therapy session, ceiling effects were present for all measures except the Functional Independence Measure (18%-33% of participants). All had strong known-groups validity (early vs late in admission and by discharge destination). All were responsive (effect sizes >1.0) and had excellent interrater reliability (intraclass correlation coefficients = 0.79-0.94).

CONCLUSION

All 4 measures were reliable, valid, and responsive; however, their clinical utility varied, and ceiling effects were common at physical therapy discharge.

IMPACT

This study is an important step toward evidence-based measurement in acute trauma physical therapy care. It provides critical information to guide assessment of mobility and physical function in acute trauma physical therapy, which may facilitate benchmarking across different hospitals and trauma centers and further progress the science and practice of physical therapy following traumatic injury.

Rocktape provides no benefit over sham taping in people with knee osteoarthritis who are completing an exercise program: a randomised trial

OBJECTIVES

To investigate if Rocktape combined with exercise is more effective than exercise and sham taping in patients with knee osteoarthritis.

DESIGN

Single institution, prospective, participant and assessor blinded, randomised study.

SETTING

Outpatient physiotherapy department of a tertiary hospital.

PARTICIPANTS

Thirty-six patients with knee osteoarthritis.

INTERVENTION

Participants were randomised to either; 1) Rocktape plus exercise or 2) sham taping plus exercise.

MAIN OUTCOME MEASURES

A linear mixed-effect model was used to assess differences between groups over time for the primary outcome measure (VAS at rest and movement) as well as the secondary outcome measures. Secondary measures included the Knee Injury and Osteoarthritis Outcome Score (KOOS), 30second sit to stand, 40m walk and stair climb tests. Exercise adherence and analgesia use were recorded via a diary. Outcomes were assessed at baseline, immediately prior to the first tape application and immediately following first taping (both at one week after baseline), then two and five weeks after first tape application.

RESULTS

There were no between group differences over time in pain at rest [median Rocktape group 0.035 (IQR -0.1 to 3.0) vs median sham 0 (IQR 0 to 1.6) mean adj diff (0.053, 95% CI -0.17 to 0.27)] or with movement [median tape group 2.45 (IQR -0.5 to 4.8) vs median sham 2.0 (IQR 0.8 to 4.1) mean adj diff 0.072, 95% CI -0.20 to 0.35]. There were no significant differences between groups in any of the KOOS subscales or performance-based tests administered over time. Pain on movement significantly improved over time in both groups, whilst pain at rest only improved at the final time point.

CONCLUSION

There was no additional benefit of Rocktape over sham tape in patients with knee osteoarthritis who were completing a home exercise program over five weeks.

Radiological features of pulmonary fat embolism in trauma patients: a case series

PURPOSE

Fat embolism syndrome (FES) is a rare complication in trauma patients (usually with long bone fractures) in which migrating medullary fat precipitates multiorgan dysfunction, classically presenting with dyspnoea, petechiae and neurocognitive dysfunction. Although this triad of symptoms is rare, it nonetheless aids diagnosis of pulmonary fat embolism (PuFE). Typical imaging features of PuFE are not established, although increasing use of CT pulmonary angiography (CTPA) in this cohort may provide important diagnostic information. We therefore conducted a case series of FES patients with CTPA imaging at a Level 1 Trauma Centre in Melbourne, Australia.

METHODS

Medical records and various radiological investigations including CTPA of consecutive patients diagnosed clinically with FES between 2006 and 2018, including demographics, injury and their progress during their admission, were reviewed.

RESULTS

Fifteen FES patients with retrievable CTPAs were included (mean age 31.2 years, range 17-69; 12 males [80%]). 93.3% had long bone fractures. CTPA was performed 2.00 ± 1.41 days post-admission. Review of these images showed pulmonary opacity in 14 (93.3%; ground-glass opacities in 9 [64.3%], alveolar opacities in 6 [42.9%]), interlobular septal thickening in 10 (66.7%), and pleural effusions in 7 (46.7%). Filling defects were identified in three (20%) CTPAs, with density measuring - 20HU to + 63HU. Ten patients (66.7%) had neuroimaging performed, with two patients demonstrating imaging findings consistent with cerebral fat emboli.

CONCLUSION

CTPA features of PuFE are variable, with ground-glass parenchymal changes and septal thickening most commonly seen. Filling defects were uncommon.

Outcomes of severe lower limb injury with Mangled Extremity Severity Score ≥ 7

AIMS

Complex fractures of the femur and tibia with associated severe soft tissue injury are often devastating for the individual. The aim of this study was to describe the two-year patient-reported outcomes of patients in a civilian population who sustained a complex fracture of the femur or tibia with a Mangled Extremity Severity Score (MESS) of ≥ 7, whereby the score ranges from 2 (lowest severity) to 11 (highest severity).

METHODS

Patients aged ≥ 16 years with a fractured femur or tibia and a MESS of ≥ 7 were extracted from the Victorian Orthopaedic Trauma Outcomes Registry (January 2007 to December 2018). Cases were grouped into surgical amputation or limb salvage. Descriptive analysis were used to examine return to work rates, three-level EuroQol five-dimension questionnaire (EQ-5D-3L), and Glasgow Outcome Scale-Extended (GOS-E) outcomes at 12 and 24 months post-injury.

RESULTS

In all, 111 patients were included: 90 (81%) patients who underwent salvage and 21 (19%) patients with surgical amputation. The mean age of patients was 45.8 years (SD 15.8), 93 (84%) were male, 37 (33%) were involved in motor vehicle collisions, and the mean MESS score was 8.2 (SD 1.4). Two-year outcomes in the cohort were poor: six (7%) patients achieved a GOS-E good recovery, the mean EQ-5D-3L summary score was 0.52 (SD 0.27), and 17 (20%) patients had returned to work.

CONCLUSION

A small proportion of patients with severe lower limb injury (MESS ≥ 7) achieved a good level of function 24 months post-injury. Further follow-up is needed to better understand the long-term trajectory of these patients, including delayed amputation, hospital readmissions, and healthcare utilization.

Substituting inpatient rehabilitation beds for home-based multidisciplinary rehabilitation: A qualitative study of patient perceptions

OBJECTIVE

To understand the patients' perspectives of the pilot Better at Home program in order to inform the development of bed substitution rehabilitation services.

METHODS

Prospective qualitative study using semi-structured interviews undertaken 3-6 months following program participation was performed. Interviews were transcribed and themes developed by two independent researchers.

RESULTS

Nineteen participants (14 females) were interviewed. Major themes found included high satisfaction with the service and a high regard for the importance of communication both within the team and with the patients. Patients had inconsistent views on the provision of services with some feeling that the program was not specific to their needs, whilst others felt it was focused and flexible. Involvement in decision-making for referral to the service was also not always fully understood.

CONCLUSION

This study provides important information that can be utilised in the development of any bed substitution home-based model of care.

Patients from residential aged care with hip fractures-Does discharge destination from acute care affect outcomes?

OBJECTIVE

The aim of this study was to describe the demographics of patients from residential aged care facilities (RACFs) who underwent fixation of hip fracture and to compare 12-month functional and mortality outcomes for those returning to their RACF with those admitted to a subacute facility (SAF) following their acute hospital stay.

METHODS

A retrospective review was undertaken of all patients from a RACF with high-level care needs admitted to Alfred Hospital, Melbourne, for fixation of hip fracture in 2014-2015. Data including demographic and hospital event details, length of stay (LOS), discharge destination and 12-month functional outcomes measured by the Glasgow Outcome Scale-Extended (GOS-E), were collected. Factors related to discharge destination and outcomes were analysed.

RESULTS

Ninety patients from a RACF were included in this study, with 68 patients (76%) returning to their RACF and 22 (24%) admitted to a SAF after acute hospital stay. Those discharged to a SAF had an average LOS at this facility of 20.79 days (SD 8.02). The SAF group also had a longer acute LOS (7 days IQR 5-10, compared to 6 days IQR 4-7.5) but there was no difference between groups at 12 months in terms of mortality or function, with 50% of all patients deceased at this time point (n = 40) and the remaining 40 patients (50%) reporting a poor functional outcome.

CONCLUSIONS

Mobility status during acute and subacute stay, and 12-month functional and mortality outcomes were similar in both groups irrespective of discharge destination, with the influence of cognition and concomitant medical issues currently unknown. Further research is required to evaluate the efficacy of current hip fracture models of care, the factors that influence clinician discharge planning decision-making and to interrogate new models of care that support rehabilitation and complex medical management in RACFs.

Predictors of clavicle fixation in multiply injured patients

Introduction

Clavicle fractures account for approximately 10% of all fractures in multiply injured patients. Our study aims to determine factors associated with surgical fixation of the clavicle fracture in multiply injured patients.

Methods

Major adult trauma patients from 2005 to 2014 with a clavicle fracture were included. Multivariate analysis was undertaken to determine the variables associated with fixation.

Results

1779 patients (median age of 47 and a median Injury Severity Score of 17) were included. 273 (15%) patients underwent clavicle fixation. Factors associated with surgical fixation of the clavicle included: year, younger age, ICU admission, or an associated humerus or scapula fracture.

Discharge destination and patient-reported outcomes after inpatient treatment for isolated lower limb fractures

OBJECTIVES

To examine the association between discharge destination (home or inpatient rehabilitation) for adult patients treated in hospital for isolated lower limb fractures and patient-reported outcomes.

DESIGN

Review of prospectively collected Victorian Orthopaedic Trauma Outcomes Registry (VOTOR) data.

SETTING, PARTICIPANTS

Adults (18-64 years old) treated for isolated lower limb fractures at four Melbourne trauma hospitals that contribute data to the VOTOR, 1 March 2007 - 31 March 2016.

MAIN OUTCOME MEASURES

Return to work and functional recovery (assessed with the extended Glasgow Outcomes Scale, GOS-E); propensity score analysis of association between discharge destination and outcome.

RESULTS

Of 7961 eligible patients, 1432 (18%) were discharged to inpatient rehabilitation, and 6775 (85%) were followed up 12 months after their injuries. After propensity score adjustment, the odds of better functional recovery were 56% lower for patients discharged to inpatient rehabilitation than for those discharged directly home (odds ratio, 0.44; 95% CI, 0.37-0.51); for the 5057 people working before their accident, the odds of return to work were reduced by 66% (odds ratio, 0.34; 95% CI, 0.26-0.46). Propensity score analysis improved matching of the discharge destination groups, but imbalances in funding source remained for both outcome analyses, and for also for site and cause of injury in the GOS-E analysis (standardised differences, 10-16%).

CONCLUSIONS

Discharge to inpatient rehabilitation after treatment for isolated lower limb fractures was associated with poorer outcomes than discharge home. Factors that remained unbalanced after propensity score analysis could be assessed in controlled trials.

Measurement of mobility and physical function in hospitalised trauma patients: A systematic review of instruments and their measurement properties

Introduction

It is well recognised that organised trauma systems reduce trauma patient mortality. As established systems mature, there is an increasing need to better understand the patient recovery trajectory. Mobility and physical function are key aspects of recovery, but the optimal instruments for measurement in the acute hospital setting remain unclear.

Methods

A systematic review was undertaken to identify and describe mobility and physical function instruments scored by direct patient assessment, in adult trauma patients in an acute hospital setting. Databases were searched with no date restrictions. Instruments that were specific to subgroups or related to individual conditions, diseases or joints were excluded. The consensus-based standards for the selection of health measurement instruments checklist was used to assess risk of bias where relevant. Clinimetric properties were reported where possible, including reliability, validity and responsiveness.

Results

Fourteen thousand one hundred and fourteen articles were identified with 37 eligible for final review, including six instruments. None had been specifically designed for use in a heterogeneous range of trauma patients. The Functional Independence Measure was the most commonly cited (n = 10 studies), with evidence of construct validity, responsiveness and minimal floor/ceiling effects (<3%). The Acute Care Index of Function (n = 1 study) was found to be valid and responsive whilst the modified Iowa Level of Assistance (n = 2 studies) was reliable and responsive, but ceiling effects ranged from 26% to 37%. Little clinimetric data were available for other measures.

Conclusion

Evidence from a few studies show promise for the use of the Functional Independence Measure, Acute Care Index of Function and modified Iowa Level of Assistance to measure mobility and physical function in trauma patients, however comprehensive clinimetric data are lacking. Future research should test these scores in specifically designed clinimetric property studies in defined trauma patient populations. This would enable the identification of a gold standard measure for evaluating treatment effectiveness, enabling benchmarking between centres, allow prediction of recovery pathways and optimise trauma patient outcomes.

Advanced musculoskeletal physiotherapists are effective and safe in managing patients with acute low back pain presenting to emergency departments

Objective The aim of this study was to compare emergency department (ED) key performance indicators for patients presenting with low back pain and seen by an advanced musculoskeletal physiotherapist (AMP) with those seen by other non-AMP clinicians (ED doctors and nurse practitioners). Methods A retrospective audit (October 2012-September 2013) was performed of data from three metropolitan public hospital EDs to compare patients with low back pain seen by AMP and non-AMP clinicians. Outcome measures included ED length of stay, ED wait time, admission rates and re-presentation to the ED. Results One thousand and eighty-nine patients with low back pain were seen during AMP service hours (360 in the AMP group, 729 in the non-AMP group). Patients seen by the AMP had a significantly shorter ED wait time (median 13 vs 32min; P<0.001) and ED length of stay (median 141 vs 175min; P<0.001). Significantly fewer patients seen by the AMP were admitted (P<0.001), and this difference remained after accounting for the difference in triage code between the groups. Conclusions Improved ED metrics were demonstrated in patients with low back pain when managed by an AMP compared with patients seen by doctors and nurse practitioners. What is known about the topic? There is a growing body of literature regarding the role of AMPs in the Australian healthcare system in providing clinical services for patients with musculoskeletal conditions, including settings such as the ED. AMPs have proven to be safe and cost-effective, achieving high patient satisfaction and improved patient outcomes. However, there is little to no information regarding their effect on ED metrics, such as ED length of stay, wait time and admission rates for patients presenting to the ED with low back pain. What does this paper add? This paper demonstrates improved ED metrics for patients presenting to the ED with low back pain when seen by an AMP compared with patients seen by doctors and nurse practitioners. The specific improved metrics for these patients were decreased admission rates, decreased ED length of stay and decreased wait time. What are the implications for clinicians? This paper provides evidence that the AMPs effectively discharge patients admitted to the ED in a timely manner, without evidence of increased readmissions, compared with their medical and nursing colleagues. Support for the role of the AMP within the ED setting is strengthened by these results.

Discharge from the acute hospital: trauma patients' perceptions of care

Objective The involvement of orthopaedic trauma patients in the decision-making regarding discharge destination from the acute hospital and their perceptions of the care following discharge are poorly understood. The aim of the present study was to investigate orthopaedic trauma patient experiences of discharge from the acute hospital and transition back into the community. Methods The present qualitative study performed in-depth interviews, between October 2012 and November 2013, with patients aged 18-64 years with lower limb trauma. Thematic analysis was used to derive important themes. Results Ninety-four patients were interviewed, including 35 discharged to in-patient rehabilitation. Key themes that emerged include variable involvement in decision-making regarding discharge, lack of information and follow-up care on discharge and varying opinions regarding in-patient rehabilitation. Readiness for discharge from in-patient rehabilitation also differed widely among patients, with patients often reporting being ready for discharge before the planned discharge date and feeling frustration at the need to stay in in-patient care. There was also a difference in patients' perception of the factors leading to recovery, with patients discharged to rehabilitation more commonly reporting external factors, such as rehabilitation providers and physiotherapy. Conclusion The insights provided by the participants in the present study will help us improve our discharge practice, especially the need to address the concerns of inadequate information provision regarding discharge and the role of in-patient rehabilitation. What is known about the topic? There is no current literature describing trauma patient involvement in decision-making regarding discharge from the acute hospital and the perception of how this decision (and destination choice; e.g. home or in-patient rehabilitation) affects their outcome. What does this paper add? The present large qualitative study provides information on patients' opinion of discharge from the acute hospital following trauma and how this could be improved from their perception. Patients are especially concerned with the lack of information provided to them on discharge, their lack of involvement and understanding of the choices made with regard to their discharge and describe concerns regarding their follow-up care. There is also a feeling from the patients that they are ready to leave rehabilitation before their actual planned discharge date, a concept that needs further investigation. What are the implications for practitioners? The patient insights gained by the present study will lead to a change in discharge practice, including increased involvement of the patient in the decision-making in terms of discharge from both the acute and rehabilitation hospitals and a raised awareness of the need to provide written information and follow-up telephone calls to patients following discharge. Further research into many aspects of patient discharge from the acute hospital should be considered, including the use of rehabilitation prediction tools to ensure patient involvement in decision-making and a discharge and/or follow-up coordinator to ensure patients are aware of how to access information after discharge.

Clinicians' perceptions of decision making regarding discharge from public hospitals to in-patient rehabilitation following trauma

Objective The aim of the present study was to investigate the perceptions of consultant surgeons, allied health clinicians and rehabilitation consultants regarding discharge destination decision making from the acute hospital following trauma. Methods A qualitative study was performed using individual in-depth interviews of clinicians in Victoria (Australia) between April 2013 and September 2014. Thematic analysis was used to derive important themes. Case studies provided quantitative information to enhance the information gained via interviews. Results Thirteen rehabilitation consultants, eight consultant surgeons and 13 allied health clinicians were interviewed. Key themes that emerged included the importance of financial considerations as drivers of decision making and the perceived lack of involvement of medical staff in decisions regarding discharge destination following trauma. Other themes included the lack of consistency of factors thought to be important drivers of discharge and the difficulty in acting on trauma patients' requests in terms of discharge destination. Importantly, as the complexity of the patient increases in terms of acquired brain injury, the options for rehabilitation become scarcer. Conclusions The information gained in the present study highlights the large variation in discharge practises between and within clinical groups. Further consultation with stakeholders involved in the care of trauma patients, as well as government bodies involved in hospital funding, is needed to derive a more consistent approach to discharge destination decision making. What is known about the topic? Little is known about the drivers for referral to, or acceptance at, in-patient rehabilitation following acute hospital care for traumatic injury in Victoria, Australia, including who makes these decisions of behalf of patients and how these decisions are made. What does this paper add? This paper provides information regarding the perceptions of acute hospital consultant surgeons and allied health, as well as rehabilitation clinicians, in terms of discharge destination decision making from the acute hospital following trauma. The use of case studies further highlights differences between, and within, these specialities with regard to this decision making. This research also highlights the importance of financial considerations as drivers of decision making, and the lack of consistency of the factors thought to be important drivers of discharge between these different clinical groupings. What are the implications for practitioners? This research shows that financial factors are significant drivers of discharge destination decision making for trauma patients. The present study highlights opportunities to engage with stakeholders (acute care, rehabilitation, administration, government and patients) to develop more consistent discharge processes that optimise the use of rehabilitation resources for those patients who could benefit from in-patient rehabilitation.

Natural history of medial clavicle fractures

BACKGROUND

Fractures of the medial third of the clavicle comprise less than 3% of all clavicle fractures. The natural history and optimal management of these rare injuries are unknown. The aim of our study is to describe the demographics, management and outcomes of patients with medial clavicle fractures treated at a Level 1 Trauma Centre.

METHODS

A retrospective review was conducted of patients presenting to our institution between January 2008 and March 2013 with a medial third clavicle fracture. Clinical and radiographic data were recorded including mechanism of injury, fracture pattern and displacement, associated injuries, management and complications. Functional outcomes were assessed using the Glasgow Outcome Scale Extended (GOS-E) scores from the Victorian Orthopaedic Trauma Outcomes Registry (VOTOR). Shoulder outcomes were assessed using two patient reported outcomes scores, the American Shoulder and Elbow Society Score (ASES) and the Subjective Shoulder Value (SSV).

RESULTS

Sixty eight medial clavicle fractures in 68 patients were evaluated. The majority of patients were male (n=53), with a median age of 53.5 years (interquartile range (IQR) 37.5-74.5 years). The most common mechanism of injury was motor vehicle accident (n=28). The in-hospital mortality rate was 4.4%. The fracture pattern was almost equally distributed between extra articular (n=35) and intra-articular (n=33). Fifty-five fractures (80.9%) had minimal or no displacement. Associated injuries were predominantly thoracic (n=31). All fractures were initially managed non-operatively, with a broad arm sling. Delayed operative fixation was performed for painful atrophic delayed union in two patients (2.9%). Both patients were under 65 years of age and had a severely displaced fracture of the medial clavicle. One intra-operative vascular complication was seen, with no adverse long-term outcome. Follow-up was obtained in 85.0% of the surviving cohort at an average of three years post injury (range 1-6 years). The mean ASES score was 80.3 (SD 24.8, range 10-100,), and the mean SSV score was 77.0 (SD 24.6, range 10-100).

CONCLUSION

Sixty eight patients with medial clavicle fractures were identified over a 5year period, with excellent functional results seen following conservative management.

Trampoline related injuries in adults

INTRODUCTION

Trampoline-related injuries in adults are uncommon. Participation in trampolining is increasing following its admission as a sport in the Olympics and the opening of local recreational trampoline centres. The aim of this study was to assess the number and outcomes of adult trampoline-related orthopaedic injuries presenting to four trauma hospitals in Victoria.

METHODS

A cohort study was performed for the period 2007-2013. Adult patients registered by the Victorian Orthopaedic Trauma Outcomes Registry (VOTOR) who had sustained a trampolining related injury were included in this study. Descriptive analyses were used to describe the patient population, the injuries sustained and their in-hospital and 6-month outcomes.

RESULTS

There was an increase in trampolining injuries from 2007 (n=3) to 2012 (n=14) and 2013 (n=18). Overall, fifty patients with a median age of 25 (range 16-66) were identified. Thirty-five patients (70%) had lower limb injuries, 20 patients (40%) had spinal injuries and one patient had an upper limb injury. Thirty-nine patients (78%) required surgery. Fractures of the tibia (n=13), ankle fractures (n=12) and cervical spine injuries (n=7) were the most common injuries; all of which required surgery. Complications included death, spinal cord injuries, compartment syndrome and open fractures. At 6 months post injury, more than half (52%) of the patients had not achieved a good recovery, 32% had some form of persistent disability, 14% did not get back to work and overall physical health for the cohort was well below population norms for the SF-12.

CONCLUSION

Adult trampoline-related injuries have increased in the last few years in this cohort identified through VOTOR. Lower limb and spinal injuries are most prevalent. Public awareness and education are important to reduce the risk for people participating in this activity.

Incidence of acute kidney injury following total joint arthroplasty: a retrospective review by RIFLE criteria

Background

Total joint arthroplasty (TJA) is a common procedure with demand for arthroplasties expected to increase exponentially. Incidence of acute kidney injury (AKI) following TJA is reportedly low, with most studies finding an incidence of <2%, increasing to 9% when emergency orthopaedic patients are included.

Methods

Retrospective medical record review of consecutive primary, elective TJA procedures was undertaken at a large tertiary hospital (Alfred). Demographic, peri-operative and post-operative data were recorded. Factors associated with AKI (based on RIFLE criteria) were determined using multiple logistic regression.

Results

Between January 2011 and June 2013, 425 patients underwent TJA; 252 total knee replacements (TKR) and 173 total hip replacements (THR). Sixty-seven patients (14.8%) developed AKI, including 51 TKR. Factors associated with AKI (adjusting for known confounders) include increasing body mass index [adjusted odds ratio (AOR) 1.14; 95% CI: 1.07, 1.21], older age (AOR 1.07; 95% CI 1.02, 1.13) and lower pre-operative glomerular filtration rate (AOR 0.97; 95% CI 0.96, 0.99) and taking angiotensin-converting enzyme inhibitors (AOR 2.70; 95% CI 1.12, 6.48) and angiotensin-II receptor blockers (AOR 2.64; 95% CI 1.18, 5.93). In most patients, AKI resolved by discharge, however, only 62% of patients had renal function tests after discharge.

Conclusions

This study showed a rate of AKI of nearly 15% in our TJA population, substantially higher than previously reported. Given that AKI and long-term complications are associated, prospective research is needed to further understand the associated factors and predict those at risk of AKI. There may be opportunities to maximize the pre-operative medical management and mitigate risk.

Eureka! A reliable, home-made water volumetry device

Background

Water displacement is considered to be the gold standard for measuring foot volume; however, it is time-consuming and infrequently used in clinical practice. The objectives of this study were to determine whether a home-made water displacement device is a reliable and time-efficient method for determining foot volume.

Methods

Thirty participants with no foot pathologies were enrolled and had their foot volume measured in two home-made water volumetry devices (Preski and PreskiLite). The participants' foot volumes were measured on two occasions on each of two different days.

Results

All measurements were achieved in less than 90 seconds. Within-day reliability was high (intraclass correlation [ICC]=0.997–0.999) with the minimal detectable change (MDC) at the 90% confidence level (MDC90) of less than 25 ml for both devices. Mean differences in volume displaced between days were small (range 0.6– -5.4 mls). For between-day measures on the same leg, the mean coefficient of variation ranged from 0.65–1 with associated ICCs of 0.989–0.997. The MDC90 for between-day measures was 46 ml for the PreskiLite and 23 ml for the Preski. The difference in volume displaced between right and left legs was less than the MDC90 for both devices.

Conclusions

A novel, home-made water volumetry device provides reliable measures of foot volume both within and between days. Measurements taken on the contralateral leg provide an adequate control. These portable devices provide rapid measurements and only one measurement is needed per day.

Discharge destination following lower limb fracture: development of a prediction model to assist with decision making

BACKGROUND

Accurate prediction of the likelihood of discharge to inpatient rehabilitation following lower limb fracture made on admission to hospital may assist patient discharge planning and decrease the burden on the hospital system caused by delays in decision making.

AIMS

To develop a prognostic model for discharge to inpatient rehabilitation.

METHOD

Isolated lower extremity fracture cases (excluding fractured neck of femur), captured by the Victorian Orthopaedic Trauma Outcomes Registry (VOTOR), were extracted for analysis. A training data set was created for model development and validation data set for evaluation. A multivariable logistic regression model was developed based on patient and injury characteristics. Models were assessed using measures of discrimination (C-statistic) and calibration (Hosmer-Lemeshow (H-L) statistic).

RESULTS

A total of 1429 patients met the inclusion criteria and were randomly split into training and test data sets. Increasing age, more proximal fracture type, compensation or private fund source for the admission, metropolitan location of residence, not working prior to injury and having a self-reported pre-injury disability were included in the final prediction model. The C-statistic for the model was 0.92 (95% confidence interval (CI) 0.88, 0.95) with an H-L statistic of χ(2)=11.62, p=0.17. For the test data set, the C-statistic was 0.86 (95% CI 0.83, 0.90) with an H-L statistic of χ(2)=37.98, p<0.001.

CONCLUSION

A model to predict discharge to inpatient rehabilitation following lower limb fracture was developed with excellent discrimination although the calibration was reduced in the test data set. This model requires prospective testing but could form an integral part of decision making in regards to discharge disposition to facilitate timely and accurate referral to rehabilitation and optimise resource allocation.

Rest easy? Is bed rest really necessary after surgical repair of an ankle fracture?

INTRODUCTION

Bed rest with elevation of the affected limb is commonly prescribed postoperatively following ankle fracture fixation although there is no evidence that this is necessary.

AIM

The aim of this prospective, randomised study was to investigate the effects of early mobilisation following surgical fixation of an ankle fracture on wound healing and length of stay (LOS).

METHOD

A total of 104 patients underwent primary internal fixation of an ankle fracture at The Alfred hospital, Melbourne between July 2008 and January 2010.

INTERVENTION

The strategy included either early mobilisation group (first day post surgery) or control group (bed rest with elevation until day 2 post surgery).

OUTCOME MEASURES

Data collected included demographic, injury type and surgical procedure. Outcome data included inpatient LOS, wound condition at 10-14 days, opioid use and re-admission rate.

RESULTS

Groups were comparable at baseline. Wound breakdown rate was 2.9% (3 patients in the control group). Median LOS of the early mobilisation group was 55 h compared with 71 h in the control group (p<0.0001). Opioid use for the control group was an average of 90 mg morphine equivalent in the first 24 h post surgery compared with 67 mg morphine equivalent for the early mobilisation group (p=0.32).

CONCLUSION

This study indicates that early mobilisation following surgical fixation of an ankle fracture results in a shorter hospital stay without evidence of an increased risk of re-admission or wound complication.

No rest for the wounded: early ambulation after hip surgery accelerates recovery

BACKGROUND

Level 3 evidence-based guidelines recommend first walk after hip fracture surgery within 48 h. Early mobilization is resource and effort intensive and needs rigorous investigation to justify implementation. This study uses a prospective randomized method to investigate the effect of early ambulation (EA) after hip fracture surgery on patient and hospital outcomes.

METHODS

Sixty patients (41 women and 19 men; mean age 79.4 years) admitted between March 2004 through December 2004 to The Alfred Hospital, Melbourne, for surgical management of a hip fracture were studied. Randomization was either EA (first walk postoperative day 1 or 2) or delayed ambulation (DA) (first walk postoperative day 3 or 4). Functional levels on day 7 post-surgery, acute hospital length of stay and destination at discharge were compared.

RESULTS

At 1 week post-surgery, patients in the EA group walked further than those in the DA group (P = 0.03) and required less assistance to transfer (P = 0.009) and negotiate a step (P = 0.23). Patients in the EA group were more likely to be discharged directly home from the acute care than those in the DA group (26.3 compared with 2.4%) and less likely to need high-level care (36.8 compared with 56%). A failed early ambulation subgroup had significantly more postoperative cardiovascular instability and worse results for all outcome measures.

CONCLUSION

EA after hip fracture surgery accelerates functional recovery and is associated with more discharges directly home and less to high-level care.
