Using outcome measure results to facilitate clinical decisions the first year after total hip arthroplasty.

STUDY DESIGN Variable-occasion, repeated-measures design. OBJECTIVES To model change in lower extremity functional status of patients 1 year after total hip arthroplasty (THA), using the Lower Extremity Functional Scale (LEFS) and the 6-minute walk test (6MWT), and, secondarily, to provide clinicians with useful data to guide practice. BACKGROUND Given the prevalence of THA and current resource pressures, standardized outcome measures play an important role in providing physical therapists with objective knowledge about postoperative recovery and prognosis. METHODS Seventy-five patients, with a mean age of 61 years and a diagnosis of hip osteoarthritis, consented to participate in the study. Assessments were conducted preoperatively and at multiple time points for up to 65 weeks postoperatively. Recovery was modeled using a nonlinear robust regression analysis for clustered data. The predictive ability of age, body mass index, and preoperative score was explored. RESULTS Gender-based recovery curves were generated to depict the rate and amount of change in LEFS scores and 6MWT distances over the first year. Preoperative baseline 6MWT distance was the only covariate predictive of postarthroplasty 6MWT distances for both males and females. None of the covariates examined were significantly associated with postarthroplasty LEFS scores. CONCLUSION Although there were variations in the recovery curves by measure, general patterns were noted. There was a rapid increase in both self-reported and physical performance measure scores for 12 to 15 weeks. Thereafter, we observed a slowing of recovery, with a plateau at 30 to 35 weeks for the 6MWT and later for the LEFS. These data can be used to make evidence-based decisions regarding prognosis and to guide the setting of measurable treatment goals. LEVEL OF EVIDENCE Prognosis, level 1b.

Patients Are Satisfied with Advanced Practice Physiotherapists in a Role Traditionally Performed by Orthopaedic Surgeons

PURPOSE To measure and compare patient satisfaction with follow-up care in advanced practice physiotherapist (APP) and orthopaedic surgeon clinics for patients following total hip or knee replacement. METHOD Consecutive patients attending either an APP-led or a surgeon-led review clinic were surveyed using a modified nine-item satisfaction questionnaire based on the Visit-Specific Satisfaction Instrument (VSQ-9). Chi-square analyses were used to examine differences in patient characteristics and type of visit. Independent t-tests were used to examine potential differences in patient satisfaction. RESULTS Of the 123 participants, more than half were aged 65 years or older. Chi-squared analyses revealed no significant difference in participant characteristics (gender, age, and overall health status) between the two different types of clinics. There was a significant difference (χ(2) (4)=12.49, p=0.014) in the distribution of the timing of follow-up appointments. There was no significant difference between the groups in mean overall patient satisfaction scores on the modified VSQ-9 (p=0.34) nor in the mean of the sum of the seven items related to the service provider (p=0.85). Satisfaction scores for most of the service-provider items were above 90/100. CONCLUSION Patients are highly satisfied with the care provided by APPs in follow-up clinics after joint replacement. Evaluation of the patient perspective is essential to any new role involving a shift in traditional practice boundaries.

Evaluation of an Advanced-Practice Physical Therapist in a Specialty Shoulder Clinic: Diagnostic Agreement and Effect on Wait Times

PURPOSE To examine the role of an advanced-practice physiotherapist (APP) with respect to (1) agreement with an orthopaedic surgeon on diagnosis and management of patients with shoulder problems; (2) wait times; and (3) satisfaction with care. METHODS This prospective study involved patients with shoulder complaints who were referred to a shoulder specialist in a tertiary care centre. Agreement was examined on seven major diagnostic categories, need for further examination and surgery, and type of surgical procedure. Wait times were compared between the APP- and surgeon-led clinics from referral date to date of initial consultation, date of final diagnostic test, and date of confirmed diagnosis and planned treatment. A modified and validated version of the Visit-Specific Satisfaction Instrument assessed satisfaction in seven domains. Kappa (κ) coefficients and bias- and prevalence-adjusted kappa (PABAK) values were calculated, and strength of agreement was categorized. Wait time and satisfaction data were examined using non-parametric statistics. RESULTS Agreement on major diagnostic categories varied from 0.68 (good) to 0.96 (excellent). Agreement with respect to indication for surgery was κ=0.75, p<0.001; 95% CI, 0.62-0.88 (good). Wait time for APP assessment was significantly shorter than wait time for surgeon consultation at all time points (p<0.001); the surgeons wait time was significantly reduced over 3 years. High satisfaction was reported in all components of care received from both health care providers. CONCLUSIONS Using experienced physiotherapists in an extended role reduces wait times without compromising patient clinical management and overall satisfaction.

Cross-cultural adaptation and implementation of Good Life with osteoarthritis in Denmark (GLA:D™): group education and exercise for hip and knee osteoarthritis is feasible in Canada

OBJECTIVE Adapt and evaluate the feasibility of implementing Good Life with osteoArthritis in Denmark (GLA:DTM) in Canada for people with mild to severe hip/knee osteoarthritis. METHODS Patients triaged to non-surgical management participated in two education sessions and 12 supervised, neuromuscular exercise classes. We used the RE-AIM implementation framework evaluating outcomes of Reach, Effectiveness/Efficacy, Adoption, Implementation and Maintenance. Patients completed surveys pre-program and at 3 months follow-up. Program fidelity was evaluated at four observations against a priori criteria. We conducted semi-structured interviews with therapists post-program. RESULTS 72 patients consented to participate, 59 started the program and one withdrew on physician advice. The remaining 58 provided follow-up data. Mean age was 67 years; 78% were female and 52% had body mass index (BMI) >25. The effect of the program was demonstrated: 40% improvement in pain with 59% achieving a clinically important improvement of ≥2 points on the Numeric Pain Rating scale. Statistically significant improvement also occurred in the Hip disability/Knee injury and Osteoarthritis Outcome Score subscales. 24% reported increased physical activity. Program fidelity was demonstrated with all criteria met. Therapists emphasized that rolling recruitment allowed appropriate supervision and resulted in participants encouraging each other. 99% of participants indicated they benefitted from and were satisfied with the program and 90% reported using the knowledge daily. 52% were willing to pay >

Impact of Radiographic Imaging of the Shoulder Joint on Patient Management: An Advanced-Practice Physical Therapist's Approach

Background Surgery for lumbar spine pain is indicated for specific etiologies. Given the majority of individuals referred to spine surgeons are not surgical candidates, care delivery is inefficient, with consultations being of limited value for most. Using specially trained physiotherapists in triage is a human resource strategy that may optimize surgeons’ time and the patient experience. Methods An advanced-practice physiotherapist (APP) and a surgeon assessed consecutive patients with lumbar spine pain presenting at an academic health centre’s spine surgery clinic. The second assessor was blinded to the outcome of the first. We used the &kgr; statistic to evaluate surgeon–APP level of chance-corrected agreement concerning patients’ need for a surgical consultation. To assess satisfaction with the APP, patients completed a modified version of the validated Visit-specific Questionnaire. Results The sample included 102 participants (54 women) with a mean age of 54.3 ± 14.3 years and a mean Oswestry Disability Index score of 35.4 ± 16.6. The assessors’ overall agreement was 86%. The &kgr; coefficient for the need for a surgical consultation was 0.69 (95% confidence interval 0.54–0.84). The APP identified that 77% of patients did not require a surgical consultation. Twenty-one patients underwent surgery. Satisfaction scores for the APP were very high (mean score 92 out of 100). Conclusion In triaging patients with lumbar spine pain, the APP and surgeon had a high level of agreement. An APP performing triage at a surgical centre can effectively reduce wait lists by 70%, reserving surgical consultations for those patients in whom they are indicated.

A qualitative study of patient education needs for hip and knee replacement

Purpose: Recent care innovations using advanced-practice physical therapists (APPs) as alternative health care providers are promising. However, information related to the clinical decision making of APPs is limited with respect to ordering shoulder-imaging investigations and the impact of these investigations on patient management. The purpose of this study was twofold: (1) to explore the clinical decision making of the APP providing care in a shoulder clinic by examining the relationship between clinical examination findings and reasons for ordering imaging investigations and (2) to examine the impact on patient management of ordered investigations such as plain radiographs, ultrasound (US), magnetic resonance imaging (MRI), and magnetic resonance arthrogram (MRA). Method: This was a prospective study of consecutive patients with shoulder complaints. Results: A total of 300 patients were seen over a period of 12 months. Plain radiographs were ordered for 241 patients (80%); 39 (13%) received MRI, 27 (9%) US, and 7 (2%) MRA. There was a relationship between clinical examination findings and ordering plain radiographs and US (ps=0.047 to <0.0001). Plain radiographs ordered to examine the biomechanics of the glenohumeral joint affected management (χ2 1=8.66, p=0.003). Finding a new diagnosis was strongly correlated with change in management for all imaging investigations (ps=0.001 to <0.0001). Conclusion: Skilled, extended-role physical therapists rely on history and clinical examination without overusing costly imaging. The most important indicator of change in management was finding a new diagnosis, regardless of the type of investigation ordered.

A Framework for the Development and Implementation of an Advanced Practice Role for Physiotherapists That Improves Access and Quality of Care for Patients

BackgroundQuality health information is key to patient engagement, self-management and an enhanced healthcare experience. There is strong evidence to support involving patients and their families in the development and evaluation of health-related educational material. These factors were the impetus for our high volume joint replacement centre to undertake a qualitative study to elicit patient experiences to inform the development of effective strategies and education along the care continuum for hip and knee replacement.MethodsPurposively selected patients from postoperative follow-up clinics were recruited to participate in a focus group or telephone interview. We developed a semi-structured interview guide that addressed four specific aspects of the patient’s experience with educational material: pre-surgery, hospital stay, recovery period and future recommendations. The focus groups and interviews continued to the point of saturation and were audio-recorded and transcribed verbatim. Interview transcripts were coded and then inductively organized into larger categories using thematic analysis.ResultsSix focus groups and seven telephone interviews were conducted, totalling 32 participants. One of the key themes that emerged was a need for more education concerning pain management post-operatively; specifically, patients wanted more information on expected levels of pain, pain medication usage, management of side effects and guidelines for weaning off the medication. There was surprising variability in patients’ descriptions of their pre-surgery, surgery and recovery experiences. These corresponded to an equally diverse range of preferences for educational content, delivery and timing. Many patients reported using the web while others preferred traditional formats for information delivery. There was some interest in receiving education using mobile technology.ConclusionsOur findings validate the importance of multi-modal patient education tailored to individual preferences and experiences, which may differ according to such characteristics as gender and age. The gap in pain management information is a critical finding for healthcare providers working with patients undergoing joint replacement. Developing pain management education in different formats that addresses frequently asked questions will enhance patient engagement and, their overall experience and recovery.
