The development and validation of a scoring tool to predict the operative duration of elective laparoscopic cholecystectomy

Background: The ability to accurately predict operative duration has the potential to optimise theatre efficiency and utilisation, thus reducing costs and increasing staff and patient satisfaction. With laparoscopic cholecystectomy being one of the most commonly performed procedures worldwide, a tool to predict operative duration could be extremely beneficial to healthcare organisations. Methods: Data collected from the CholeS study on patients undergoing cholecystectomy in UK and Irish hospitals between 04/2014 and 05/2014 were used to study operative duration. A multivariable binary logistic regression model was produced in order to identify significant independent predictors of long (> 90 min) operations. The resulting model was converted to a risk score, which was subsequently validated on second cohort of patients using ROC curves. Results: After exclusions, data were available for 7227 patients in the derivation (CholeS) cohort. The median operative duration was 60 min (interquartile range 45–85), with 17.7% of operations lasting longer than 90 min. Ten factors were found to be significant independent predictors of operative durations > 90 min, including ASA, age, previous surgical admissions, BMI, gallbladder wall thickness and CBD diameter. A risk score was then produced from these factors, and applied to a cohort of 2405 patients from a tertiary centre for external validation. This returned an area under the ROC curve of 0.708 (SE = 0.013, p  90 min increasing more than eightfold from 5.1 to 41.8% in the extremes of the score. Conclusion: The scoring tool produced in this study was found to be significantly predictive of long operative durations on validation in an external cohort. As such, the tool may have the potential to enable organisations to better organise theatre lists and deliver greater efficiencies in care

The effect of body mass index and preoperative weight loss in people with obesity on postoperative outcomes to 6 months following total hip or knee arthroplasty: a retrospective study

Abstract Background Few studies have investigated the association between obesity, preoperative weight loss and postoperative outcomes beyond 30- and 90-days post-arthroplasty. This study investigated whether body mass index (BMI) and preoperative weight loss in people with obesity predict postoperative complications and patient-reported outcomes 6 months following total knee or hip arthroplasty. Methods Two independent, prospectively collected datasets of people undergoing primary total knee or hip arthroplasty for osteoarthritis between January 2013 and June 2018 at two public hospitals were merged. First, the sample was grouped into BMI categories, < 35 kg/m2 and ≥ 35 kg/m2. Subgroup analysis was completed separately for hips and knees. Second, a sample of people with BMI ≥ 30 kg/m2 was stratified into participants who did or did not lose ≥ 5% of their baseline weight preoperatively. The presence of postoperative complications, Oxford Hip Score, Oxford Knee Score, EuroQol Visual Analogue Scale and patient-rated improvement 6 months post-surgery were compared using unadjusted and adjusted techniques. Results From 3,552 and 9,562 patients identified from the datasets, 1,337 were included in the analysis after merging. After adjustment for covariates, there was no difference in postoperative complication rate to 6 months post-surgery according to BMI category (OR 1.0, 95%CI 0.8–1.4, P = 0.8) or preoperative weight loss (OR 1.1, 95%CI 0.7–1.8, P = 0.7). There was no between-group difference according to BMI or preoperative weight change for any patient-reported outcomes 6 months post-surgery. Conclusion Preoperative BMI or a 5% reduction in preoperative BMI in people with obesity was not associated with postoperative outcomes to 6 months following total knee or hip arthroplasty

Taking the first step: protocol for a cluster randomised implementation trial comparing strategies on access to exercise programmes for people with knee osteoarthritis

Introduction This cluster randomised implementation trial will assess the effect of two behavioural change interventions on the proportion of people with structural knee osteoarthritis (OA) referred and attending exercise-based professionals (physiotherapists and exercise physiologists). The interventions are designed to increase awareness of guidelines, benefits and access pathways for exercise therapy. We hypothesise either strategy will result in more people with knee OA being referred and attending physiotherapy/exercise physiology than current standard of care.Methods and analysis We will recruit 30 radiology clinics. 10 clinics will be randomly assigned to each trial arm with 1020 people with knee OA consecutively recruited (102 people per practice) into each arm. Intervention arm 1 is an educational reminder message targeted at primary care practitioners with a hyperlink to national guidelines regarding knee OA clinical management. It will be included in the reporting template of a plain knee X-ray. Intervention arm 2 is the reminder message and a patient-facing infographic explaining the benefits and access pathways for exercise. Both interventions will be delivered once, by the radiology clinics, when a person undergoes plain X-ray for non-traumatic knee pain/dysfunction. The primary outcome is referral to physiotherapist/exercise physiology. The secondary outcome is attendance to that appointment. Both outcomes are self-reported via an online survey administered 4 weeks after the X-ray. Additional survey questions explore facilitators and barriers to appointment attendance and acceptability of the interventions. A subsample of the intervention groups will be recruited for semistructured telephone-based interviews to further explore these latter outcomes.Ethics and dissemination The study protocol was approved by Macquarie University Human Research Ethics Committee (#520221190343842) and prospectively registered with the Australian New Zealand Clinical Trials Registry. The findings of the trial will be disseminated through peer-reviewed scientific journals and conferences. We will engage with Australian physician colleges and main-stream media to distribute findings.Trial registration number ACTRN12622001414707p

Preliminary insights into patient preparedness for knee or hip arthroplasty: a descriptive survey study

Abstract Objective Knowledge-based preparedness for surgery is achieved through education. It is unclear which of brief or extended education programs prior to knee or hip arthroplasty provides better patient preparedness. Using the Patient Preparedness for Surgery survey, we investigated whether people awaiting arthroplasty attending a hospital that provided education over multiple visits via a pre-surgery management program (‘Extended’) report superior preparedness compared to those attending a hospital in the same health district that only provides education at the pre-admission clinic assessment (‘Brief’). Results A consecutive sample of 128 people (n = 101, ‘Extended’, n = 27 ‘Brief’) completed the anonymized survey. COVID-19 related service disruptions undermined the sample size, reducing statistical power. The pre-specified superiority of the Extended program (a relative 20% more reporting ‘agree’/’strongly agree’) was not observed for ‘Overall preparedness’ [95% (Extended) vs. 89% (Brief), p = 0.36]. Between-group differences exceeding 20% relative superiority were observed for three preparedness sub-domains [‘Alternatives explained’ (52 vs. 33%, p = 0.09); ‘Prepared for home’ (85 vs. 57%, p < 0.01); ‘Recall of complications’ (42 vs 26%, p = 0.14)]. The preliminary findings suggest an extended education program potentially yields better patient-reported preparedness in some preparedness sub-domains, but not all

A mixed methods approach to investigating physical activity in people with obesity participating in a chronic care programme awaiting total knee or hip arthroplasty

Aims: To describe patient-reported physical activity and step count trajectory and explore perceived barriers and enablers to physical activity amongst people with obesity participating in a chronic care programme whilst awaiting arthroplasty. Design: Convergent parallel mixed-method study. Method: A patient cohort derived from a longitudinal sample of adults with end-stage osteoarthritis and obesity from a chronic care programme whilst awaiting primary total knee or hip arthroplasty (n = 97) was studied. Physical activity was measured at baseline (entry to the wait list) and before surgery (9–12 months waiting time) using the Lower Extremity Activity Scale (LEAS) and activity monitors (activPAL™). A subset of participants completed in-depth semi-structured interviews 6 months after being waitlisted to explore perceived barriers and enablers to physical activity. Themes were inductively derived and then interpreted through the COM-B model. Results: Baseline LEAS and activPAL™ data were available from 97 and 63 participants, respectively. The proportion of community ambulant individuals reduced from 43% (95% CI 33%–53%) at baseline to 17% (95% CI 9%–28%) pre-surgery. Paired activPAL™ data (n = 31) for step count, upright time, and stepping time remained unchanged. Twenty-five participants were interviewed. Five themes underpinning physical activity were mapped to the COM-B model components of capability (physical capability), opportunity (accessibility and social norms), and motivation (self-efficacy and beliefs and physical activity). Conclusions: Participation in a chronic care programme did not improve physical activity levels for people with obesity awaiting arthroplasty. Programs cognisant of the COM-B model components may be required to address the natural trajectory of declining physical activity levels while awaiting arthroplasty

Why do some people with osteoarthritis and obesity awaiting hip or knee arthroplasty achieve successful weight management? A qualitative study

Aim: To explore perceived barriers and enablers to weight management among people with obesity awaiting total knee or hip arthroplasty. Design: A nested qualitative study within a multi-centre, quasi-experimental pilot study comparing usual care weight management to a dietitian-led weight-loss diet. Methods: Semi-structured individual interviews were conducted with adults with end-stage osteoarthritis and a body mass index ≥30 kg/m2 waitlisted for primary total knee or hip arthroplasty. Participants with diverse sociodemographic characteristics and varied success with weight management in the pilot study were purposively sampled. Interviews were analysed using inductive thematic analysis, underpinned by constructivist–interpretivist epistemology. The Patient Activation Measure and Health Literacy Questionnaire were used for context when interpreting the findings. Results: Twenty-five participant interviews were conducted with a sociodemographically varied sample (aged 44–80 years, 9 born in Australia, 6 in paid employment and 11 lost ≥5% of their baseline weight). Four identified themes underpinned successful weight management: beliefs, adaptability, navigating healthcare and sociocultural context. Beliefs about whether weight was perceived as a problem, the expectation of weight loss and treatment-related beliefs influenced participants\u27 perspectives towards weight loss. Adaptability, the ability to overcome barriers to weight loss, comprised three subthemes; readiness to act, degree of independence and problem-solving skills. Approaches towards navigating healthcare influenced uptake and adherence to weight management recommendations. Importantly, these themes were dependent on social and environmental circumstances, which influenced the type of barriers experienced and resources available to the individual. Conclusion: Differences in a person\u27s beliefs, their ability to adapt and navigate healthcare and sociocultural context appear to explain successful weight management among people with end-stage arthritis. Implications for the profession and/or patient care: Clinicians should allow for individualisation cognisant of the identified themes when providing advice and treatment to promote adherence to weight management interventions. Impact: This study explored perceived barriers and enablers to weight management among people with obesity awaiting total knee or hip arthroplasty. Four identified themes underpinned successful weight management: beliefs, adaptability, navigating healthcare and sociocultural context. Beliefs about whether weight was perceived as a problem, the expectation of weight loss and treatment-related beliefs influenced participants\u27 perspectives towards weight loss. Understanding and assessing the contribution of each factor may guide weight management from clinicians treating patients with obesity and osteoarthritis. Reporting Method: The data are reported using the COREQ guidelines. Patient or Public Contribution: Patients contributed to the data collected

The feasibility of implementing a cultural mentoring program alongside pain management and physical rehabilitation for chronic musculoskeletal conditions: results of a controlled before-and-after pilot study

Abstract Background Culturally diverse communities face barriers managing chronic musculoskeletal pain conditions including navigation challenges, sub-optimal healthcare provider engagement and difficulty adopting self-management behaviours. Objectives To explore the feasibility and trends of effectiveness of implementing a cultural mentoring program alongside clinical service delivery. Methods This quasi-experimental controlled before-and-after multiple case study was conducted in three hospital-based services that provide treatment for patients with musculoskeletal pain. Two prospective cohorts, a pre-implementation and a post-implementation cohort, of adults with chronic musculoskeletal pain who attended during the 6-month recruitment phase, were eligible if they self-identified with one of the cultures prioritised for mentoring by the clinic. The pre-implementation cohort received routine care for up to 3-months, while the post-implementation cohort received up to 3-months of cultural mentoring integrated into routine care (3 to 10 sessions), provided by a consumer (n = 6) with lived experience. Feasibility measures (recruitment and completion rates, attendance, satisfaction), and trends of effectiveness (Patient Activation Measure and Health Literacy Questionnaire items one and six) were collated over 3-months for both cohorts. Outcomes were presented descriptively and analysed using Mann-Whitney U-tests for between-group comparisons. Translation and transcription of post-treatment semi-structured interviews allowed both cohorts’ perspectives of treatment to be analysed using a Rapid Assessment Process. Results The cultural mentor program was feasible to implement in clinical services with comparable recruitment rates (66% pre-implementation; 61% post-implementation), adequate treatment attendance (75% pre-implementation; 89% post-implementation), high treatment satisfaction (97% pre-implementation; 96% post-implementation), and minimal participant drop-out (< 5%). Compared to routine care (n = 71), patients receiving mentoring (n = 55) achieved significantly higher Patient Activation Measure scores (median change 0 vs 10.3 points, p < 0.01) at 3-months, while Health Literacy Questionnaire items did not change for either cohort over time. Three themes underpinned participant experiences and acceptability of the mentoring intervention: ‘expectational priming’, ‘lived expertise’ and ‘collectivist orientation’ to understand shared participant experiences and explore the potential differential effect of the mentoring intervention. Conclusion Participant experiences and observations of improved patient activation provide support for the acceptability of the mentoring intervention integrated into routine care. These results support the feasibility of conducting a definitive trial, while also exploring issues of scalability and sustainability

The Natural Helper approach to culturally responsive disease management: protocol for a type 1 effectiveness-implementation cluster randomised controlled trial of a cultural mentor programme

Introduction Chronic disease is a leading cause of death and disability that disproportionately burdens culturally and linguistically diverse (CALD) communities. Self-management is a cornerstone of effective chronic disease management. However, research suggests that patients from CALD communities may be less likely to engage with self-management approaches. The Natural Helper Programme aims to facilitate patient engagement with self-management approaches (ie, ‘activation’) by embedding cultural mentors with lived experience of chronic disease into chronic disease clinics/programmes. The Natural Helper Trial will explore the effect of cultural mentors on patient activation, health self-efficacy, coping efforts and health-related quality of life (HRQoL) while also evaluating the implementation strategy.Methods and analysis A hybrid type-1 effectiveness-implementation cluster-randomised controlled trial (phase one) and a mixed-method controlled before-and-after cohort extension of the trial (phase 2). Hospital clinics in highly multicultural regions in Australia that provide healthcare for patients with chronic and/or complex conditions, will participate. A minimum of 16 chronic disease clinics (clusters) will be randomised to immediate (active arm) or delayed implementation (control arm). In phase 1, the active arm will receive a multifaceted strategy supporting them to embed cultural mentors in their services while the control arm continues with usual care. Each cluster will recruit an average of 15 patients, assessed at baseline and 6 months (n=240). In phase 2, clusters in the control arm will receive the implementation strategy and evaluate the intervention on an additional 15 patients per cluster, while sustainability in active arm clusters will be assessed qualitatively. Change in activation over 6 months, measured using the Patient Activation Measure will be the primary effectiveness outcome, while secondary effectiveness outcomes will explore changes in chronic disease self-efficacy, coping strategies and HRQoL. Secondary implementation outcomes will be collected from patient–participants, mentors and healthcare providers using validated questionnaires, customised surveys and interviews aligning with the Reach, Effectiveness, Adoption, Implementation, Maintenance framework to evaluate acceptability, reach, dose delivered, sustainability, cost-utility and healthcare provider determinants.Ethics and dissemination This trial has full ethical approval (2021/ETH12279). The results from this hybrid trial will be presented at scientific meetings and published in peer-reviewed journals.Trial registration number ACTRN12622000697785
