Synthesis of 'joint class' curricula at high volume joint replacement centres and a preliminary model for development and evaluation.

RATIONALE: Preoperative patient education through 'joint class' has potential to improve quality of care for total joint replacement (TJR). However, no formal guidance exists regarding curriculum content, potentially resulting in inter-institutional variation. OBJECTIVE: We aimed to (a) synthesize curriculum components of 'joint classes' across high-volume institutions and (b) develop a preliminary theory of change model for development and evaluation guided by the existing curricula and related literature. METHODS: We reviewed 'joint class' curricula from the websites of the 10 highest-volume TJR centres (by average annual 2017-2019 volume) that publicly disclosed this information. Two reviewers qualitatively compared available content and noted common categories, which were synthesized into key domains across institutions. We then reviewed the PubMed database for literature on pre-TJR patient education and education needs in the past 10 years. Drawing on our curriculum synthesis and related literature, we proposed a theory of change model: hypothesized mechanisms through which 'joint class' confers benefits to patients and health systems. RESULTS: We identified 30 categories in our review of existing class content, which we synthesized into seven key domains: (I) Practical Elements, (II) Logistics, (III) Medical Information, (IV) Modifiable Risk Factors, (V) Expected Outcomes, (VI) Patient Role in Recovery and (VII) Enhanced Education. Variation across institutions was noted. Our preliminary model based on the curriculum synthesis and related literature on the impact of 'joint class' includes three levels: (1) Practical Elements ('joint class' accessibility and information quality), (2) Class Goals (increased health literacy, increased adherence, risk mitigation, realistic expectations, and reduced anxiety) and (3) Target Outcomes (improved clinical outcomes, positive patient experience and increased patient satisfaction). CONCLUSION: Our synthesis identified core common topics included in pre-TJR education but also highlighted variation across institutions, supporting opportunities for standardization. Clinicians and researchers can use our preliminary model to systematically develop and evaluate 'joint classes,' with the goal of establishing a standard of care for TJR preoperative education.

Wide-Field (15â€Š× 9 mm) Swept-Source Optical Coherence Tomography Angiography Following Plaque Radiotherapy of Choroidal Melanoma: An Analysis of 105 eyes.

PURPOSE: The aim of this study was to evaluate retinal microvascular abnormalities following plaque radiotherapy of choroidal melanoma (CM) using wide-field swept-source optical coherence tomography angiography (OCTA). DESIGN: Single-centre retrospective review. METHODS: Retrospective case series of 105 CM patients treated with I-125 plaque radiotherapy and imaged with wide-field (15 × 9 mm) SS-OCTA from March 2018 to August 2018 at the Ocular Oncology Service, Wills Eye Hospital (Philadelphia, PA). RESULTS: At mean follow-up of 49 months (range 4-297) after plaque radiotherapy, there were 52 eyes (50%) with clinically evident radiation retinopathy (CERR) and 53 eyes (50%) without CERR. Comparison (CERR vs controls) revealed foveal avascular zone enlargement (1.7 vs 0.23 mm, P = 0.03) and reduction of capillary vascular density (CVD) in the superficial and deep plexus in the total wide-field (43% vs 47%, P < 0.001, and 46% vs 48%, P = 0.001, respectively), peripapillary region (66% vs 77%, P < 0.001, and 66% vs 72%, P = 0.001, respectively), and papillomacular bundle (60% vs 68%, P < 0.001, and 61% vs 64%, P = 0.03, respectively). Comparison (no CERR vs controls) revealed nonsignificant foveal avascular zone enlargement (1.20 vs 0.23 mm, P = 0.16) and reduction of CVD in the superficial plexus (46% vs 47%, P = 0.008), and not the deep plexus (48% vs 48%, P = 0.42) of the total wide-field. Comparison of irradiated eyes (CERR vs no CERR) showed reduction of CVD in the superficial and deep plexus of the total wide-field (43% vs 46%, P < 0.006, and 46% vs 48% P < 0.02, respectively), peripapillary region (66% vs 74%, P < 0.001, and 66% vs 72% P < 0.01, respectively), and superficial plexus in the papillomacular bundle (60% vs 65%, P = 0.03). CONCLUSIONS: Following plaque radiotherapy for choroidal melanoma, wide-field swept-source optical coherence tomography angiography demonstrates retinal microvascular abnormalities in the CVD in eyes with and without CERR. These findings are important in early detection and monitoring of radiation retinopathy.
