Total knee arthroplasty (TKA) was the most frequently performed inpatient operating room procedure in the United States in 2012.¹ From 2003 to 2012, the incidence of TKA increased from 145.4 to 223.0 per 100 000 population (a 4.9% mean annual increase), with the total number performed in the United States projected to increase from 711 000 in 2011 to 3.48 million by 2030.² Similarly in Australia, the incidence increased from 108.3 per 100 000 population in 2003 to 222.3 per 100 000 population in 2017, with more than 54 000 TKAs performed in 2017.³

Introduction: Palliative care is a complex area for student placements due to the high level of grief and loss encountered. There is limited research into allied health student experiences in palliative care. The aim of this study was to investigate the attitudes, behaviours, perceptions and personal challenges faced by allied health students in palliative care. We sought to explore student preparation for a palliative care clinical placement and the impact of the placement on their self-efficacy in the areas of communication, patient management and interdisciplinary teamwork. Methods: Eleven consecutive eligible allied health students undertaking a placement in palliative care were recruited to participate in this study. Each participant took part in a semi-structured interview at the beginning and end of their placement. Interviews were transcribed and analysed qualitatively. Questionnaires were also given to participant’s pre and post placement to identify the impact of self-efficacy and outcome expectancies on learning outcomes. Results: The analysis of the results demonstrated that most, but not all, of participants experienced anxiety prior to placement. Participants’ perception and understanding of palliative care was positively influenced by their placement, and there were a wide variety of learning experiences described. Conclusions: Allied health student placements in palliative care provide a positive environment for student learning and can be altered to maximise the learning experience. With careful planning, and by encouraging a culture of support, effective approaches and strategies can be identified to make a placement in palliative care more appealing and appropriate for individual students.

To understand private consumer and clinician preferences towards different rehabilitation modes following knee or hip arthroplasty, and identify factors which influence the chosen rehabilitation pathway. Mixed methods cross-sectional study involving 95 semi-structured interviews of consumers (patients and carers) and clinicians (arthroplasty surgeons, physiotherapists and rehabilitation physicians) in Sydney, Australia, during 2014–2015. Participants were asked about the acceptability of different modes of rehabilitation provision, and factors influencing their chosen rehabilitation pathway. Interviews were in person or via the telephone. Qualitative analysis software was used to electronically manage qualitative data. An analytical approach guided data analysis. Pre-operative preferences strongly influenced the type of rehabilitation chosen by consumers. Key factors that influenced this were both intrinsic and extrinsic, including; the previous experience of self or known others, the perceived benefits of the chosen mode, a sense of entitlement, the role of orthopaedic surgeons and influence of patient preference, a patient’s clinical status post-surgery, the private hospital business model and insurance provider involvement. The acceptability of rehabilitation modes varied between clinician groups. No one rehabilitation mode provided following arthroplasty is singularly preferred by stakeholders. Factors other than the belief that a particular mode was more effective than another appear to dominate the pathway followed by private arthroplasty consumers, indicating evidence-based policies around rehabilitation provision may have limited appeal in the private sector.

Importance Formal rehabilitation programs, including inpatient programs, are often assumed to optimize recovery among patients after undergoing total knee arthroplasty. However, these programs have not been compared with any outpatient or home-based programs. Objective To determine whether 10 days of inpatient rehabilitation followed by a monitored home-based program after total knee arthroplasty provided greater improvements than a monitored home-based program alone in mobility, function, and quality of life. Design, Setting, and Participants In this 2-group, parallel, randomized clinical trial, including a nonrandomized observational group, conducted at 2 public, high-volume arthroplasty hospitals in Sydney, Australia (July 2012-December 2015), 940 patients with osteoarthritis undergoing primary total knee arthroplasty were screened for eligibility. Of the 525 eligible patients consecutively invited to participate, 165 were randomized either to receive inpatient hospital rehabilitation and home-based rehabilitation or to receive home-based rehabilitation alone, and 87 patients enrolled in the observation group. Interventions Eighty-one patients were randomized to receive 10 days of hospital inpatient rehabilitation followed by an 8-week clinician-monitored home-based program, 84 were randomized to receive the home-based program alone, and 87 agreed to be in the observational group, which included only the home-based program. Main Outcomes and Measures Mobility at 26 weeks after surgery, measured with the 6-minute walk test. Secondary outcomes included the Oxford Knee Score, which ranges from 0 (worst) to 48 (best) and has a minimal clinically important difference of 5 points; and EuroQol Group 5-Dimension Self-Report Questionnaire (EQ-5D) visual analog scale, which ranges from 0 (worst) to 100 (best), and has a minimal clinically important difference of 23 points. Results Among the 165 randomized participants, 68% were women, and the cohort had a mean age, 66.9 years (SD, 8.4 years). There was no significant difference in the 6-minute walk test between the inpatient rehabilitation and either of the 2 home program groups (mean difference, −1.01; 95% CI, −25.56 to 23.55), nor in patient-reported pain and function (knee score mean difference, 2.06; 95% CI, −0.59 to 4.71), or quality of life (EQ-5D visual analog scale mean difference, 1.41; 95% CI, −6.42 to 3.60). The number of postdischarge complications for the inpatient group was 12 vs 9 among the home group, and there were no adverse events reported that were a result of trial participation. Conclusions and Relevance Among adults undergoing uncomplicated total knee arthroplasty, the use of inpatient rehabilitation compared with a monitored home-based program did not improve mobility at 26 weeks after surgery. These findings do not support inpatient rehabilitation for this group of patients. Trial Registration clinicaltrials.gov Identifier:NCT01583153

The 6-minute walk test (6MWT) is a commonly used metric for measuring change in mobility after knee arthroplasty, however, what is considered an improvement after surgery has not been defined. The determination of important change in an outcome assessment tool is controversial and may require more than one approach. This study, nested within a combined randomised and observational trial, aimed to define a minimal important improvement threshold for the 6MWT in a knee arthroplasty cohort through a triangulation of methods including patient-perceived anchor-based thresholds and distribution-based thresholds. Individuals with osteoarthritis performed a 6MWT pre-arthroplasty then at 10 and 26 weeks post-surgery. Each rated their perceived improvement in mobility post-surgery on a 7-point transition scale anchored from “much better” to “much worse”. Based on these responses the cohort was dichotomised into ‘improved’ and ‘not improved’. The thresholds for patient-perceived improvements were then identified using two receiver operating curve methods producing sensitivity and specificity indices. Distribution-based change thresholds were determined using two methods utilising effect size (ES). Agreement between the anchor- and distribution-based methods was assessed using kappa. One hundred fifty-eight from 166 participants in the randomised cohort and 222 from 243 in the combined randomised and observational cohort were included at 10 and 26 weeks, respectively. The slightly or more patient-perceived improvement threshold at 26 weeks (an absolute improvement of 26 m) was the only one to demonstrate sensitivity and specificity results both better than chance. At 10- and 26-weeks, the ES based on the mean change score divided by the baseline standard deviation (SD), was an absolute change of 24.5 and 37.9 m, respectively. The threshold based on a moderate ES (a 0.5 SD of the baseline score) was a change of 55.0 and 55.4 m at 10- and 26-weeks, respectively. The level of agreement between the 26-week anchor-based and distribution-based minimal absolute changes was very good (k = 0.88 (95 % CI 0.81 0.95)). A valid threshold of improvement for the 6MWT can only be proposed for changes identified from baseline to 26 weeks post-surgery. The level of agreement between anchor- and distribution-based methods indicates that a true minimal or more threshold of meaningful improvement following surgery is likely within the ranges proposed by the triangulation of all four methods, that is, 26 to 55 m.

Formal rehabilitation programs are often assumed to be required after total knee arthroplasty to optimize patient recovery. Inpatient rehabilitation is a costly rehabilitation option after total knee arthroplasty and, in Australia, is utilized most frequently for privately insured patients. With the exception of comparisons with domiciliary services, no randomized trial has compared inpatient rehabilitation to any outpatient based program. The Hospital Inpatient versus HOme (HIHO) study primarily aims to determine whether 10 days of post-acute inpatient rehabilitation followed by a hybrid home program provides superior recovery of functional mobility on the 6-minute walk test (6MWT) compared to a hybrid home program alone following total knee arthroplasty. Secondarily, the trial aims to determine whether inpatient rehabilitation yields superior recovery in patient-reported function.
