In the Unites States, approximately 24% of people undergoing primary total knee or total hip arthroplasty (TKA, THA) are chronic opioid users pre-operatively. Few studies have examined the incidence of opioid use prior to TKA/THA and whether it predicts outcomes post-surgery in the Australian context. The aim was to determine: (i) the proportion of TKA and THA patients who use opioids regularly (daily) pre-surgery; (ii) if opioid use pre-surgery predicts (a) complication and readmission rates to 6-months post-surgery, (b) patient-reported outcomes to 6-months post-surgery. A retrospective cohort study was undertaken utilising linked individual patient-level data from two independent databases comprising approximately 3500 people. Patients had surgery between January 2013 and June 2018, inclusive at Fairfield and Bowral Hospitals. Following data linkage, analysis was completed on 1185 study participants (64% female, 69% TKA, mean age 67 (9.9)). 30% were using regular opioids pre-operatively. Unadjusted analyses resulted in the following rates in those who Adjusted regression analyses controlling for multiple co-variates indicated no significant association between pre-op opioid use and adverse events/patient-reported outcomes. Pre-operative opioid use was high amongst this Australian arthroplasty cohort and was not associated with increased risk of adverse events post-operatively. Further research is needed in assessing the relationship between the amount of pre-op opioid use and the risk of post-operative adverse events.
There have been no studies assessing the acceptability of opioid tapering in the pre-arthroplasty setting. This qualitative study aimed to (1) explore barriers and facilitators to opioid tapering amongst patients with chronic non-cancer pain (CNCP), and (2) explore the similarities and differences in acceptability of opioid tapering between pre-arthroplasty patients and those participating in a biopsychosocial pain management program. From January 2021, adult participants diagnosed with CNCP and taking opioids daily (any dose at time of screening for a period of 3 months) were recruited from either Fairfield Orthopaedic Hip and Knee Service (FOHKS) or Liverpool Hospital Pain Clinic (LHPC). Semi-structured interviews underwent thematic analysis using the framework method. 17 participants were recruited (FOHKS, n=9, mean age 67, female 77%, LHPC, n=8, mean age 54, female 63%). Both groups had participants who; (i) were reluctant to use opioid medications and used them out of “necessity”, (ii) were reluctant to taper due to concerns of worsening pain, quality of life, (iii) believed opioids were “toxins” causing bodily harm. Some FOHKS participants believed tapering should be a post-operative focus, whilst others believed tapering opioids pre-operatively will assist in post-op pain management. Few LHPC participants felt dependent/addicted to opioids, thus driving their intention to taper opioids. The belief of tapering opioids causing worse pain was based on either previous experiences or concerns alone. Some FOHKS participants were more inclined to taper opioids if they were educated on the chronic and peri-operative risks associated with using opioids at time of arthroplasty. Opioid users recognise the harms associated with chronic opioid use and believe they are used out of desperation for adequate analgesia, function, and quality of life. Tapering opioids in the pre-arthroplasty context may need coupling with patient education highlighting the importance of opioid tapering pre-operatively.
The purpose of this prospective pilot study is to examine the feasibility of a physiotherapist led rapid access shoulder screening clinic (RASC). The goal of this study is to assess for improvements in patient access to care, patient reported outcome measures, patient reported experience measures, and cost outcomes using time driven activity based costing methods. Patient recruitment began in January 2021. Consultation requests from general practitioners and emergency rooms are analyzed and triaged through a central system. One half of patients awaiting consultation were triaged to the traditional route used at our center while the other half were triaged to be assessed at the RASC. Outcome measures consisting of the Simple Shoulder Test and SF-12 were recorded at the initial consultation and at follow up appointments. Cost benefit analysis was conducted using time driven activity based costing methods (TD-ABC). From January to August of 2021, 123 new patients were triaged for RASC assessment. On average, the RASC gets 10 new referrals per month. As of September 2021, there are 65 patients still on waitlist for RASC assessment with 58 having been assessed. Of the 58, 11% were discharged through the RASC, 48% pursued private physiotherapy, 14% had injections, 19% proceeded on for surgical consultation, and 8% did not show. Over time same time period, approximately 15 new patients were seen in consultation by the surgeon's office. Thirty-five responses were obtained from RASC patients during their initial intake assessment. The average age of respondents was 54.7 with 21 females and 14 males. Median SF-12 scores in the physical dimension (PCS-12) for RASC patients were 36.82 and mental (MCS-12) 49.38927. Median Simple Shoulder Test scores measured 6. Of the patients who responded to the follow up questionnaires after completing physiotherapy at the RASC, both the SF-12 and Simple Shoulder Test scoring improved. Median PCS-12 measured 47.08, MCS-12 of 55.87, and Simple Shoulder Test measured 8. RASC assessments by PT saved $172.91 per hour for consultation and $157.97 per hour for patient follow ups. Utilization of a physiotherapy led rapid access shoulder clinic resulted in improvements in patient outcomes as measured by the SF-12 and Simple Shoulder Test as well as significant direct cost savings. Proper triage protocols to identify which patients would be suitable for RASC assessment, buy-in from physiotherapists, and timely assessment of patients for early initiation of rehabilitation for shoulder pain is paramount to the success of a RASC system at our centre. Future research direction would be geared to analyzing a larger dataset as it becomes available.
Musculoskeletal (MSK) disorders continue to be a major cause of pain and disability worldwide. The mission statement of the Canadian Orthopaedic Association (COA) is to “promote excellence in orthopaedic and musculoskeletal health for Canadians,” and orthopaedic surgeons serve as leaders in addressing and improving musculoskeletal health. However, patients with MSK complaints most commonly present first to a primary care physician. According to a survey of family physicians in British Columbia, 13.7-27.8% of patients present with a chief complaint that is MSK-related (Pinney et Regan, 2001). Therefore, providing excellent MSK care to Canadians requires that all physicians, especially those involved in primary care, be adequately trained to diagnose and treat common MSK conditions. To date, there has been no assessment of the total mandatory MSK training Canadian family medicine residents receive. It is also unclear, despite the prevalence of MSK complaints among Canadian patients, if current family physicians are competent or confident in their ability to provide fundamental MSK care. The purpose of this study is to determine the amount of mandatory MSK training Canadian family medicine residents are currently receiving. Web-based research was used to determine how many weeks of mandatory MSK training was incorporated into current Canadian family medicine residency training programs. This information was gathered from either the Canadian Resident Matching Service website (carms.ca) or the residency program's individual website. If this information was not available on a program's website, a program administrator was contacted via email in order to ascertain this information directly. MSK training was considered to be any rotation in orthopaedic surgery, spine surgery, sports medicine, or physiatry. 156 Canadian family medicine residency training sites were identified. Information pertaining to mandatory MSK education was collected for 150 sites (95.5%). Of the 150 training sites, 102(68 %) did not incorporate any mandatory MSK training into their curriculum. Of the 48 programs that did, the average number of weeks of MSK training was 3.37 weeks. 32/48 programs (66.7%) included 4 weeks of MSK training, which represents 3.8% of a 2-year training program. Current Canadian family medicine residents are not receiving sufficient musculoskeletal training when compared to the overall frequency of musculoskeletal presentations in the primary care setting. Understanding current family medicine physicians’ surveyed confidence and measured competence with respect to diagnosing and treating common musculoskeletal disorders could also prove helpful in demonstrating the need for increased musculoskeletal education. Future orthopaedic initiatives could help enhance family medicine MSK training.
The optimal approach to arthroscopic repair of the rotator cuff is controversial, and both single row and double row fixation methods are commonly used. Which construct yields the highest efficacy is not clear. Given the current era of increasing costs in which health care delivery models are aiming for improved efficiencies and optimal outcomes, a cost-effectiveness study was performed to inform the decision making process of the utilisation of single versus double row repair. The purpose of this study was to evaluate the cost-effectiveness of single row versus double row constructs in patients undergoing arthroscopic rotator cuff repair. A cost-utility analysis was performed. Health resource use and outcome data were obtained from a previous prospective randomised controlled trial in which 90 patients were randomised to two treatment arms, single row rotator cuff repair (n=48) and double row (n=42). The patients were followed over a two-year span from the time of initial surgery. Unit cost data were captured using case costs collected from the hospital database and the Ontario Schedule of Benefits. Utility values were derived from published literature. The incremental cost effectiveness ratio (ICER), defined as the difference in cost between the two types of rotator cuff fixation divided by the difference in quality adjusted life years (QALY), was determined. Double row fixation was more costly ($2,279.94 versus $1,587.37) but was more effective than the single row method (QALY of 4.073 versus 4.055). An incremental cost-effectiveness ratio was estimated to be $38,504.92 per QALY for double row fixation relative to single row. This is well below the commonly used willingness to pay threshold of $50,000/QALY. Subgroup analysis demonstrated that patients with larger rotator cuff tears (>3cm) had a lower ICER, suggesting that double-row fixation may be more cost-effective in more severe tears. Double row rotator cuff fixation is a cost-effective option compared to single row rotator cuff repair with an ICER of $38,504.92/QALY, well within the accepted willingness to pay threshold of $50,000/QALY. Furthermore, the ICER between single and double row fixation improved with larger rotator cuff tears (>3cm), suggesting an additional benefit of a double row construct in those cases.
