Merit-Based Incentive Payment System: How Are Plastic Surgeons Performing?

PURPOSE: Merit-based incentive payment system (MIPS) is a payment model implemented to promote high-value care through performance-based adjustments of Medicare reimbursements. Higher scores indicate superior performance in healthcare quality, efficiency, and interoperability, which can result in financial advantages. Given the paucity of literature, we aimed to characterize plastic surgery performance in MIPS. METHOD: The Centers for Medicare and Medicaid Services (CMS) online data repository was queried for data on MIPS performance of plastic surgeons from 2019-2021. Descriptive analyses and multivariable logistic regression were conducted to identify predictors of receiving bonus payment for exceptional performance. RESULTS: Approximately 1400 surgeons were sampled in each year. The median number of Medicare beneficiaries and percent of dually eligible beneficiaries-eligible for Medicare and Medicaid-were higher in 2019 (p<0.001). Beneficiary median HCC risk score, which measures expected healthcare costs and needs based on health status, was lower in 2021 (p<0.001). The most common reporting schema was reporting as a group. Total MIPS score increased from 2019 to 2020 to 2021 (90.2 vs 96.4 vs 98.3, p<0.001), but quality score progressively decreased (98.8 vs 95.5 vs 89.90, p<0.001). Fewer physicians received positive adjustment and bonus payments in 2020 and 2021. Predictors of receiving bonus payments were reporting as an alternative payment model, practice size >24, and having 10-49% of dually eligible beneficiaries (p<0.05). CONCLUSION: Understanding performance of plastic surgeons in MIPS can guide future policy direction and ensure that high-quality care translates into improved patient outcomes across all fields and levels of social vulnerability.

Virtual Reality Simulation of Airway Management Post-Cleft Palate Surgery: A Model for Sustainable and Equitable Education.

BACKGROUND: The effectiveness of virtual-reality (VR) simulation-based training in cleft surgery has not been tested. The purpose of this study was to evaluate learners' acceptance of VR simulation in airway management of a pediatric patient post-cleft palate repair. METHODS: This VR simulation was developed through collaboration between BioDigital and Smile Train. 26 medical students from a single institution completed 10 min of standardized VR training and 5 min of standardized discussion about airway management post-cleft palate repair. They spent 4-8 min in the VR simulation with guidance from a cleft surgery expert. Participants completed pre- and post-surveys evaluating confidence in using VR as an educational tool, understanding of airway management, and opinions on VR in surgical education. Satisfaction was evaluated using a modified Student Evaluation of Educational Quality questionnaire and scored on a 5-point Likert scale. Wilcoxon signed-rank tests were performed to evaluate responses. RESULTS: There was a significant increase in respondents' confidence using VR as an educational tool and understanding of airway management post-cleft palate repair after the simulation (P < .001). Respondents' opinions on incorporating VR in surgical education started high and did not change significantly post-simulation. Participants were satisfied with VR-based simulation and reported it was stimulating (4.31 ± 0.88), increased interest (3.77 ± 1.21), enhanced learning (4.12 ± 1.05), was clear (4.15 ± 0.97), was effective in teaching (4.08 ± 0.81), and would recommend the simulation (4.2 ± 1.04). CONCLUSION: VR-based simulation can significantly increase learners' confidence and skills in airway management post-cleft palate repair. Learners find VR to be effective and recommend its incorporation in surgical education.

Abbe Flap Division Before Two Weeks' Time: Harmful or Advantageous?

INTRODUCTION: The Abbe flap is a standard intervention to treat upper lip deformities in patients with bilateral cleft lip. This two-stage procedure requires a 2 to 3-week period in which the superior and inferior lips remain connected. This study evaluates the safety of Abbe flap division and inset prior to 14 days' time. MATERIALS AND METHODS: A single institution, 8-year review of all patients with a bilateral cleft lip who underwent Abbe flap reconstruction was performed. Patients were classified into two groups: those whom division was performed 14 days or later and those with division earlier than 14 days. RESULTS: A total of 26 patients were identified. Patients who underwent Abbe flap division in less than 14 days (n = 10) demonstrated an average time to division of 9.7 days (range 7-13 days) with no evidence of flap loss, wound breakdown or infection. Patients who underwent Abbe flap division within 14 days or more (n = 16) demonstrated an average time to division of 15 days with four minor complications and no flap loss. CONCLUSION: Dividing the Abbe flap after the first postoperative week appears to be safe and without additional risk to flap loss or wound breakdown. A shorter time to Abbe flap division may decrease the burden of care on patients and their caregivers.

Genomic insights into a Pseudomonas amygdali isolate from Hibiscus rosa-sinensis.

The taxonomy of Pseudomonas has been extensively studied, yet the determination of species is currently difficult because of recent taxonomic changes and the lack of complete genomic sequence data. We isolated a bacterium causing a leaf spot disease on hibiscus (Hibiscus rosa-sinensis). Whole genome sequencing revealed similarity to Pseudomonas amygdali pv. tabaci and pv. lachrymans. The genome of this isolate (referred to as P. amygdali 35-1) shared 4987 genes with P. amygdali pv. hibisci, but possessed 204 unique genes and contained gene clusters encoding putative secondary metabolites and copper resistance determinants. We predicted this isolate's type III secretion effector (T3SE) repertoire and identified 64 putative T3SEs, some of which are present in other P. amygdali pv. hibisci strains. Assays showed that the isolate was resistant to copper at a concentration of 1.6 mM. This study provides an improved understanding of the genomic relatedness and diversity of the P. amygdali species.

Novel Arthrometer for Quantifying In Vivo Knee Laxity in Three Planes Following Total Knee Arthroplasty.

BACKGROUND: Knee instability is a leading cause of dissatisfaction following total knee arthroplasty (TKA). Instability can involve abnormal laxity in multiple directions including varus-valgus (VV) angulation, anterior-posterior (AP) translation, and internal-external rotation (IER). No existing arthrometer objectively quantifies knee laxity in all three of these directions. The study objectives were to verify the safety and assess reliability of a novel multiplanar arthrometer. METHODS: The arthrometer utilized a five degree-of-freedom instrumented linkage. Two examiners each conducted two tests on the leg that had received a TKA of 20 patients (mean age 65 years (range, 53-75); 9 men, 11 women), with nine and eleven distinct patients tested at 3-month and 1-year postoperative time points, respectively. AP forces from -10 to 30 Newtons, VV moments of ±3 Newton-meters, and IER moments of ±2.5 Newton-meters were applied to each subject's replaced knee. Severity and location of knee pain during testing were assessed using a visual analog scale. Intraexaminer and interexaminer reliabilities were characterized using intraclass correlation coefficients. RESULTS: All subjects successfully completed testing. Pain during testing averaged 0.7 (out of possible 10; range, 0-2.5). Intraexaminer reliability was >0.77 for all loading directions and examiners. Interexaminer reliability and 95% confidence intervals were 0.85 (0.66-0.94), 0.67 (0.35-0.85), and 0.54 (0.16-0.79) in the VV, IER, and AP directions, respectively. CONCLUSION: The novel arthrometer was safe for evaluating AP, VV, and IER laxities in subjects who had received TKA. This device could be used to examine relationships between laxity and patient perceptions of knee instability.
