The impact of waiting for total joint replacement on pain and functional status: a systematic review

OBJECTIVE To systematically describe changes in pain and functioning in patients with osteoarthritis (OA) awaiting total joint replacement (TJR), and to assess determinants of this change. METHODS MEDLINE, EMBASE, CINAHL and Cochrane Database were searched through June 2008. The reference lists of eligible publications were reviewed. Studies that monitored pain and functioning in patients with hip or knee OA during the waiting list for TJR were analyzed. Data were collected with a pre-specified collection tool. Methodological quality was assessed and a best-evidence analysis was performed to summarize results. RESULTS Fifteen studies, of which two were of high quality, were included and involved 788 hip and 858 knee patients (mean age 59-72 and main wait 42-399 days). There was strong evidence that pain (in hip and knee OA) and self-reported functioning (in hip OA) do not deteriorate during a <180 days wait. Conflicting evidence was established for the change on self-reported functioning in patients with knee OA waiting <180 days. Moreover, strong evidence was found for an association between the female gender and intensified pain. CONCLUSION Patients with OA do not experience deterioration in pain or self-reported functional status whilst waiting <180 days for TJR. Changes over a longer waiting period are unclear. To strengthen and complement the present evidence, further high-quality studies are needed, in which preferably also performance-based measures are used.

Short-Term Natural Recovery of Ankle Sprains Following Discharge From Emergency Departments

STUDY DESIGN Prospective cohort study. OBJECTIVES To examine the natural recovery from grade I and II ankle injuries over a 1-month period. BACKGROUND There is a high rate of injury recurrence and persistence of symptoms following ankle sprains, suggesting that these injuries may not be adequately managed. However, little is known about the recovery process after discharge from emergency departments. METHODS AND MEASURES Clinical assessment of ankle swelling, strength, and joint mobility and laboratory assessment of peak torque and joint range of motion (ROM) were performed 4 and 30 days following initial clinical assessment in the emergency department. Analyses for repeated measures determined change over time and differences between injured and noninjured ankles. Self-assessed ankle function was evaluated on day 4 and day 30, and its relationship to clinical and laboratory assessments determined. RESULTS Forty-six subjects entered the study and complete datasets were obtained from 28. Significant swelling, weakness, and mobility restrictions were evident on initial assessment. Symptoms improved over time and, while clinical variables were normal by day 30, laboratory assessment indicated weakness of plantar flexors and limited active and passive ROM at 1 month. Swelling and reduced passive ROM were associated with overall function and limitations in sports and recreation activities, as well as quality of life 1 month postinjury. CONCLUSION Clinically assessed strength and ankle dorsiflexion mobility suggested full recovery at 1 month post injury, yet more sensitive measures of ankle impairment and performance detected residual deficits. Persistent impairment and incomplete recovery of self-assessed function suggest the need for management beyond standard emergency department care. Associations between impairment measures and function may provide guidance for treatment intervention.

Diagnostic and treatment concordance between a physiotherapist and an orthopedic surgeon – A pilot study

Musculoskeletal impairments affect one-third of the adult population, are one of the major contributors to lost time from work, and account for one-third of a general practitioners caseload. These injuries respond well to physiotherapy, but access can be limited in a publicly funded health care system. Improved access to physiotherapy occurs in a collaborative model of care in orthopedic clinics however the extent to which the patient receives similar diagnoses and treatment recommendations has not been reported. The purpose of this study was to determine diagnostic concordance and accuracy, and treatment concordance between a physiotherapist and orthopedic surgeons. Twenty-five subjects in an orthopedic clinic were assessed by a physiotherapist and an orthopedic surgeon. Diagnosis and treatment recommendations were made by each separately. These were compared for concordance between professionals and diagnostic accuracy. The physiotherapist and the orthopedic surgeon had 90% concordance in diagnoses of knee and shoulder impairments, and 75% accuracy when compared to definitive diagnostic methods. They had 87% agreement in treatment recommendations, however, the physiotherapist gave three treatment recommendations per patient where the surgeon gave two. In a collaborative care context therefore, this study suggests, that physiotherapists have similar diagnostic capabilities to orthopedic surgeons, and they will enhance the conservative treatment options offered to orthopedic patients.

Effect of early supervised physiotherapy on recovery from acute ankle sprain: randomised controlled trial

Objective To assess the efficacy of a programme of supervised physiotherapy on the recovery of simple grade 1 and 2 ankle sprains. Design A randomised controlled trial of 503 participants followed for six months. Setting Participants were recruited from two tertiary acute care settings in Kingston, ON, Canada. Participants The broad inclusion criteria were patients aged ≥16 presenting for acute medical assessment and treatment of a simple grade 1 or 2 ankle sprain. Exclusions were patients with multiple injuries, other conditions limiting mobility, and ankle injuries that required immobilisation and those unable to accommodate the time intensive study protocol. Intervention Participants received either usual care, consisting of written instructions regarding protection, rest, cryotherapy, compression, elevation, and graduated weight bearing activities, or usual care enhanced with a supervised programme of physiotherapy. Main outcome measures The primary outcome of efficacy was the proportion of participants reporting excellent recovery assessed with the foot and ankle outcome score (FAOS). Excellent recovery was defined as a score ≥450/500 at three months. A difference of at least 15% increase in the absolute proportion of participants with excellent recovery was deemed clinically important. Secondary analyses included the assessment of excellent recovery at one and six months; change from baseline using continuous scores at one, three, and six months; and clinical and biomechanical measures of ankle function, assessed at one, three, and six months. Results The absolute proportion of patients achieving excellent recovery at three months was not significantly different between the physiotherapy (98/229, 43%) and usual care (79/214, 37%) arms (absolute difference 6%, 95% confidence interval −3% to 15%). The observed trend towards benefit with physiotherapy did not increase in the per protocol analysis and was in the opposite direction by six months. These trends remained similar and were never statistically or clinically important when the FAOS was analysed as a continuous change score. Conclusions In a general population of patients seeking hospital based acute care for simple ankle sprains, there is no evidence to support a clinically important improvement in outcome with the addition of supervised physiotherapy to usual care, as provided in this protocol.

A comprehensive framework and key guideline recommendations for the provision of evidence-based breast cancer survivorship care within the primary care setting

BACKGROUND Breast cancer survivors continue to experience physical and psychosocial health care needs post-treatment. Primary care involvement is increasing as cancer centres move forward with earlier discharge of stable breast cancer survivors to primary care follow-up. Research suggests primary care providers (PCPs) are willing to provide survivorship care but many lack knowledge and confidence to provide evidence-based care. Although clinical practice guidelines (CPGs) exist for follow-up surveillance and certain aspects of survivorship care, no single comprehensive guideline addresses all significant breast cancer survivorship issues encountered in primary care. PURPOSE The purpose of this research was to create a comprehensive clinical practice framework to guide the provision of breast cancer survivorship care in primary care settings. METHODS This study consisted of an extensive search, appraisal and synthesis of CPGs for post-treatment breast cancer care using a modified Delphi method. Breast cancer survivorship issues and relevant CPGs were mapped to four essential components of survivorship care to create a comprehensive clinical practice framework to guide provision of breast cancer survivorship care. RESULTS The completed framework consists of a one-page checklist outlining breast cancer survivorship issues relevant to primary care, a three-page summary of key recommendations and a one-page list of guideline sources. The framework and key guideline recommendations were verified by a panel of experts for comprehensiveness, importance and relevance to primary care. CONCLUSIONS This framework may serve as a tool to remind PCPs about issues impacting breast cancer survivors, as well as the evidence-based recommendations and resources to provide the associated care.

Do People with Disabilities Have Difficulty Finding a Family Physician

Primary care has been ideally characterized as the medical home for all citizens, and yet recent data shows that approximately 6% do not have a family physician, and only 17.5% of family practices are open to new patients. Given acknowledged shortages of family physicians, this research asks the question: Do people with disabilities have particular difficulty finding a family physician? Health Care Connect (HCC) is a government-funded agency in Ontario Canada, designed to “help Ontarians who are without a family health care provider to find one”. Using data from HCC, supplemented by interviews with HCC staff, the study explores the average wait time for patients with disabilities to be linked with a primary care physician, and the challenges faced by agency staff in doing so. The study found that disabled registrants with the program are only slightly disadvantaged in terms of wait times to find a family physician, and success rates are ultimately comparable; however, agency staff report that there are a number of significant challenges associated with placing disabled patients.

Changes in Self-Reported Disability after Performance-Based Tests in Obese and Non-Obese Individuals Diagnosed with Osteoarthritis of the Knee.

Abstract Purpose: The purposes of this study are three-fold: (1) To examine whether the WOMAC questionnaire should be obtained before or after performance-based tests. (2) To assess whether self-reported disability scores before and after performance-based tests differ between obese and non-obese individuals. (3) To observe whether physical activity and BMI predict self-reported disability before and after performance based tests. Methods: A longitudinal study included thirty one participants diagnosed with knee osteoarthritis (OA) using the Kellgren-Lawrence Scale by an orthopedic surgeon. Results: All WOMAC scores were significantly higher after as compared to before the completion of performance-based tests. This pattern of results suggested that the WOMAC questionnaire should be administered to individuals with OA after performance-based tests. The obese OA was significantly different compared to the non-obese OA group on all WOMAC scores. Physical activity and BMI explained a significant proportion of variance of self-reported disability. Conclusion: Obese individuals with knee OA may over-estimate their ability to perform physical activities, and may under-estimate their level of disability compared to non-obese individuals with knee OA. In addition, self-reported physical activity seems to be a strong indicator of disability in individuals with knee OA, particularly for individuals with a sedentary life style. Implications for Rehabilitation Osteoarthritis is a progressive joint disabling condition that restricts physical function and participation in daily activities, particularity in elderly individuals. Obesity is a comorbidity commonly associated with osteoarthritis and it appears to increase self-reported disability in those diagnosed with osteoarthritis of the knee. In a relatively small sample, this study recommends that rehabilitation professionals obtain self-report questionnaires of disability after performance-based tests in obese individuals with osteoarthritis of the knee as they are more likely to give an accurate representation of their level of ability at this time.

Perspectives on the International Classification of Functioning, Disability, and Health: Child and Youth Version (ICF-CY) and Occupational Therapy Practice

ABSTRACT Classifying disability for children and youth has typically meant describing a diagnosis or developmental lag. The publication of the International Classification of Functioning, Disability and Health: Child & Youth version (ICF-CY) marks a global paradigm shift in the conceptualization and classification of childhood disability. Knowledge and awareness of the ICF-CY has been slow to diffuse within occupational therapy. Purpose. The purpose of this paper is to foster the integration of the ICF-CY into occupational therapy practice with children and youth. Key issues. Research describes positive trends in using the ICF-CY for cross-disciplinary communication; further clarity and development is warranted around activity and participation categories and functional profiles. Implications. Occupational therapy can contribute to the evolution of the ICF-CY, but must clarify its complementary perspective and knowledge base. If the ICF-CY can be further integrated into occupational therapy systems, it holds promise for shifting practice patterns and creating professional opportunities.

Using developmental research to design innovative knowledge translation technology for spinal cord injury in primary care: Actionable Nuggets™ on SkillScribe™

Abstract Context/Objective Actionable Nuggets™ for spinal cord injury (SCI) are a knowledge translation tool facilitating evidence-based primary care practice, originally developed in 2010 and refined in 2013. Evaluation results from these two phases of development have informed the design of SkillScribe™, an innovative electronic platform intended to offer reflective continuing medical education (CME) programming through mobile devices in order to support the key features of the Actionable Nuggets™ approach. This brief article describes the ongoing development of Actionable Nuggets™ for SCI on SkillScribe™ by: (1) summarizing the work to date on Actionable Nuggets™; (2) describing evaluation results of Actionable Nuggets™; (3) placing SkillScribe™ in the context of adult education. Design Developmental Research Design. Setting Canadian primary care. Participants Primary care physicians; specialist physicians. Interventions Twenty educational modules on SCI. Outcome measures Pre- and post-test knowledge survey, feedback and use statistics, impact assessment survey, qualitative analysis of evaluation data. Results In both hard copy and electronic form, physicians report that Actionable Nuggets™ are an acceptable and useful approach to providing CME for low-prevalence, high-impact conditions like SCI. The key elements of this tool are that they: offer evidence-based information in small, focused “nuggets”; position information where physicians most frequently seek it; offer information in a format that permits direct translation into action in primary care; allow time for reflection; attach practice tools; and offer CME credit. Conclusion Actionable Nuggets™ for SCI, delivered using a convenient and portable electronic medium, with time-released content and interactive testing has the potential to improve the primary care of patients with SCI.

Assessment of Knee Pain in Obese and Non-Obese Individuals Diagnosed with Osteoarthritis of the Knee Before and After Performance-Based Tests: A Pilot Study

Objective: 1) To examine whether self-reported pain, measured with the Western Ontario McMaster University Osteoarthritis Index pain subscale and Visual Analog Scale, of individuals diagnosed with knee Osteoarthritis would change after performance-based tests were completed; irrespective of their body weight and Body Mass Index. 2) To assess whether self-reported pain before and after performance-based tests differs between obese and non-obese individuals and whether both VAS and WOMAC scales of pain would demonstrate similar changes from before to after the completion of performance-based tests in obese and non-obese individuals with knee OA. 3) To observe whether depressive symptoms and BMI explain the variance of self-reported pain before and after performance based tests. Methods: This pilot study included 31 participants diagnosed with radiographic knee osteoarthritis by an orthopedic surgeon using the Kellgren-Lawrence Scale. The sample was divided in two groups of obese individuals with knee Osteoarthritis and non-obese individuals with knee osteoarthritis. Two self-reported measures, the Western Ontario McMaster University Osteoarthritis Index and Visual Analog Scale assessed knee pain before and after performance-based tests in these two groups of individuals. Depressive symptom was obtained with Back depression questionnaire II. Results: The Visual Analog Scale ratings showed a significant increase in pain in both groups, but the Western Ontario McMaster University Osteoarthritis Index pain subscale only captured a significant increase in the obese osteoarthritis group. A significant proportion of variance in pain before and after functional activities was explained by depressive symptoms and obesity, with higher levels of depression and obesity predicting worse reports of pain. Conclusion: The Visual Analog Scale pain rating may be a better tool for assessing knee pain of obese and non-obese individuals diagnosed with knee osteoarthritis. Furthermore, symptoms of depression might predict increase in knee pain and disability in obese individuals.
