Exploring Physical Therapist Adherence to Clinical Guidelines When Treating Patients With Knee Osteoarthritis in Australia: A Mixed Methods Study.

OBJECTIVE: The authors aimed to understand how physical therapists used practice guidelines to manage patients with knee osteoarthritis (OA) in Australia. METHODS: This study used a concurrent triangulation mixed-method approach to explore how physical therapists applied clinical guidelines when managing patients with knee OA in an outpatient setting via completion of a semi-structured interview. Interviews were thematically analyzed by 2 investigators using an inductive approach. Themes were then triangulated to the results of an audit that evaluated the level of adherence to respective areas in the clinical guidelines among physical therapists at the participating site. RESULTS: One main theme and 3 subthemes were identified from 18 participants: (1) physical therapists were most confident in applying guidelines to improving range of movement and strength; (2) lack of knowledge in prescription of aerobic exercise, weight, and pain management; (3) pain is a bigger barrier in areas where knowledge is lacking; and (4) lack of clarity around the scope of practice. Themes converged with the reported level of adherence to guidelines. CONCLUSIONS: Physical therapists commonly include range of movement and muscle strength exercises when managing people with knee OA. However, they were less confident in prescribing aerobic exercise and recommending weight and pain management strategies. IMPACT: Apart from the need to upskill physical therapists in the aforementioned areas of clinical practice, the role of a physical therapist in the management of people with knee OA requires further clarification.

The impact of wrist fracture, surgical repair and immobilization on patients: a qualitative study.

OBJECTIVE: To investigate patients' experience following wrist fracture, surgical repair and immobilization. DESIGN: A qualitative investigation involving individual participant interviews. SETTING: A metropolitan trauma service. SUBJECTS: In all, 31 participants were consecutively recruited from three groups within a randomized controlled trial comparing immobilization for one ( n = 11), three ( n = 10) or six weeks ( n = 10) following surgical treatment for wrist fracture. INTERVENTION: Individual interviews were conducted within three months of cast removal. Questions prompted discussion of the experience of fracture, surgery and immobilization. Interviews were audio-recorded, transcribed verbatim. At least two independent researchers performed coding and theming following principles of thematic analysis. RESULTS: Two themes were identified: (1) impact of the injury varies widely and (2) health care consumers want trustworthy dialogue. Participant reports indicated that recovery from wrist fracture, surgery and immobilization is challenging with significant changes to social role and increased dependence. For many, lack of empathy from health professionals and limited acknowledgement of the personal impact of injury led to dissatisfaction. Health professionals did not consistently tailor communication or adopt strategies to address specific needs for pain management, education and support requirements. There was no evidence that processes were implemented to enhance participant recall and comprehension. Most participants experienced their cast as a barrier to function. However, within the group of participants immobilized for one week, a number felt the cast was removed too soon. CONCLUSION: Participant reports indicate that recovery from surgically repaired wrist fracture is challenging. Opportunities exist to refine care in pain management, education and active engagement of patients in their care.

Reliability of radiographic measurements for acute distal radius fractures.

BACKGROUND: The management of distal radial fractures is guided by the interpretation of radiographic findings. The aim of this investigation was to determine the intra- and inter-observer reliability of eight traditionally reported anatomic radiographic parameters in adults with an acute distal radius fracture. METHODS: Five observers participated. All were routinely involved in making treatment decisions based on distal radius fracture radiographs. Observers performed independent repeated measurements on 30 radiographs for eight anatomical parameters: dorsal shift (mm), intra-articular gap (mm), intra-articular step (mm), palmar tilt (degrees), radial angle (degrees), radial height (mm), radial shift (mm), ulnar variance (mm). Intraclass correlation coefficients (ICCs) and the magnitude of retest errors were calculated. RESULTS: Measurement reliability was summarised as high (ICC > 0.80), moderate (0.60-0.80) or low (<0.60). Intra-observer reliability was high for dorsal shift and palmar tilt; moderate for radial angle, radial height, ulnar variance and radial shift; and low for intra-articular gap and step. Inter-observer reliability was high for palmar tilt; moderate for dorsal shift, ulnar variance, radial angle and radial height; and low for radial shift, intra-articular gap and step. Error magnitude (95 % confidence interval) was within 1-2 mm for intra-articular gap and step, 2-4 mm for ulnar variance, 4-6 mm for radial shift, dorsal shift and radial height, and 6-8° for radial angle and palmar tilt. CONCLUSIONS: Based on previous reports of critical values for palmar tilt, ulnar variance and radial angle, error margins appear small enough for measurements to be useful in guiding treatment decisions. Our findings indicate that clinicians cannot reliably measure values ≤1 mm for intra-articular gap and step when interpreting radiographic parameters using the standardised methods investigated in this study. As a guide for treatment selection, palmar tilt, ulnar variance and radial angle measurements may be useful, but intra-articular gap and step appear unreliable.
