Contextualizing Breast Implant Removal Patterns with Google Trends: Big Data Applications in Surgical Demand.

The demand for breast implant removal (BIR) has increased substantially in recent years. This study leveraged large datasets available through Google Trends to understand how changes in public perception could be influencing surgical demand, both geographically and temporally. METHODS: Using Google Trends, we extracted relative search volume for BIR-related search terms in the United States from 2006 to 2019. A network of related search terms was established using pairwise correlative analysis. Terms were assessed for correlation with national BIR case volume based on annual reports provided by the American Society of Plastic Surgeons. A surgical demand index for BIR was created on a state-by-state basis. RESULTS: A network of internally correlated BIR search terms was found. Search volumes for such terms, including "explant" [ρ = 0.912], "breast implant removal" [ρ = 0.596], "breast implant illness" [ρ = 0.820], "BII" [ρ = 0.600], and "ALCL" [ρ = 0.895] (P < 0.05), were found to be positively correlated with national BIR case volume, whereas "breast augmentation" [ρ = -0.596] (P < 0.05) was negatively correlated. Our 2019 BIR surgical demand index revealed that Nevada, Arizona, and Louisiana were the states with the highest BIR demand per capita. CONCLUSIONS: Google Trends is a powerful tool for tracking public interest and subsequently, online health information seeking behavior. There are clear networks of related Google search terms that are correlated with actual BIR surgical volume. Understanding the online health queries patients have can help physicians better understand the factors driving patient decision-making.

Clinical Competency Committees in Plastic Surgery Residency.

BACKGROUND: Clinical competency committees (CCCs) are now an Accreditation Council on Graduate Medical Education (ACGME) requirement for plastic surgery training programs. They serve to monitor resident progress and make formal recommendations to program directors on promotion, remediation, and dismissal, based on resident progress toward the curricular milestones. METHODS: Here, we present an overview on building, conducting, and improving a CCC, reviewing the literature available regarding best practices regarding this novel assessment system, with attention to the particular requirements for plastic surgery training. RESULTS: We present the results of the Duke University CAQCC as a case study in the efficacy of a well-executed group in terms of improved resident outcomes, particularly regarding In-service Examination scores as an objective measure. CONCLUSIONS: Rather than simply serving as a necessary ACGME dictum, the CCC has the opportunity to demonstrably improve resident education. This article is valuable for department leaders, program directors, faculty, and residents toward understanding the purpose and design of their CCC.

Disparities between Operative Time and Relative Value Units for Plastic Surgery Procedures.

BACKGROUND: Plastic surgeons are evaluated not only by the number of patients served but also by relative value, quantified by the Medicare relative value unit system, which can affect advancement and compensation. Procedures that demand a high operative time without an increase in relative value units are, by definition, inefficient. The purpose of this study was to determine whether the number of relative value units actually corresponds to operative time. METHODS: The National Surgical Quality Improvement Program data sets over a 9-year period were queried for plastic surgery operations. The primary CPT codes representing the 100 most common operations were compared for operative time and total relative value units. RESULTS: A total of 53,701 cases were included. There was a high degree of correlation between operative time and number of relative value units (Pearson correlation coefficient, 0.82). The average efficiency was 10.201 ± 3.386 relative value units per hour. Pressure ulcer excisions and breast reconstruction were among the most efficient (e.g., Excision, sacral pressure ulcer, CPT 19357, generated 20.819 relative value units per hour). Skin excisions, débridements, and flap delays were among the least efficient (e.g., Excision, excessive skin and subcutaneous tissue, CPT 15847, generated 1.752 relative value units per hour). CONCLUSIONS: As a general trend, the most common plastic surgical procedures requiring longer operative times are associated with more relative value units. Cases with higher relative value units assigned tended to be more efficient. For the 100 most common procedures, relative value units and operative time are not evenly distributed. These data suggest modifications to the current relative value unit designation system to more equally allocate these units based on effort and time.

Patient demand for plastic surgeons for every US state based on Google searches.

INTRODUCTION: As a profession, plastic surgeons must meet the public demand for esthetic and reconstructive procedures. Patients search for physicians using Google, which offers insights into patient needs through their search history. METHODS: The Google Trends Relative Search Volumes (RSV) were pulled for all searches for "plastic surgery" over 12 months. The number of active plastic surgeons per state was divided by Census Bureau population estimates to calculate the surgeons-per-capita value, or "surgical concentration." The Google score divided by this concentration yields a "surgical demand index" for each state. RESULTS: Florida, New York, and Connecticut had the greatest concentration of surgeons per ten-thousand people (0.220, 0.217, and 0.209, respectively), while Wyoming, Arkansas, and Vermont had the smallest (0.051, 0.071, 0.080). California exhibited the greatest number of Google searches (RSV=100), followed by Florida and Hawaii (RSV=95). Oregon (RSV=38), Virginia (RSV=52), and Alaska (RSV=58) had the fewest searches. The "surgical demand index" was greatest in Wyoming (1187.778), Oklahoma (993.751), and Arkansas (974.664) and smallest in Oregon (264.682), Virginia (320.716), and Connecticut (354.872). CONCLUSION: The distribution of US plastic surgeons is not homogeneous. The Google data suggest that some markets (e.g. Oregon) are saturated while others (e.g. Wyoming) have significant demand that is not met by the number of plastic surgeons in those states.

Does Realism Matter? A Randomized Controlled Trial Comparing Models for Medical Student Suture Education.

BACKGROUND: We hypothesized that medical students trained in suturing using high-fidelity models (cadaveric tissue) would demonstrate greater proficiency when compared with those trained using low-fidelity models (synthetic tissue). METHODS: Forty-three medical students were randomized into 2 groups. Group 1 consisted of students taught to perform simple interrupted sutures using synthetic tissue, and group 2 consisted of those taught using human cadaveric tissue. Suturing proficiency was measured pre- and postinstruction using the Global Rating Scale and by measuring suture accuracy. Perceived confidence in suturing was measured on a scale of 0-100. RESULTS: Perceived confidence was measured as an average of 8.26 out of 100 pretraining and significantly improved after training (56.91 out of 100); however, there was no significant difference when comparing confidence between groups posttraining (57.65 cadaveric versus 56.05 synthetic; P = 0.78), nor in the measured confidence change pre- and posttraining (P = 0.53). Posttraining, participants displayed a significant improvement in the number of adequately placed sutures; however, there was no significant difference posttraining when comparing groups (2.43 cadaveric versus 2.75 synthetic; P = 0.48). The change in adequate suture placement pre- and posttraining did not reach statistical significance between groups (P = 0.27). After instruction, participants demonstrated a significant improvement in total suture performance scores; however, there was no significant difference when comparing groups (30.04 cadaveric versus 29.80 synthetic; P = 0.90), nor in the total change pre- and posttraining (P = 0.74). CONCLUSIONS: Training medium fidelity (tissue versus synthetic) does not significantly influence a student's overall suturing performance. However, formal instruction significantly improves objective competence and perceived confidence. Regardless of the model, surgical departments should emphasize medical student exposure to basic surgical skills education.

The impact of local genome sequence on defining heterochromatin domains.

Characterizing how genomic sequence interacts with trans-acting regulatory factors to implement a program of gene expression in eukaryotic organisms is critical to understanding genome function. One means by which patterns of gene expression are achieved is through the differential packaging of DNA into distinct types of chromatin. While chromatin state exerts a major influence on gene expression, the extent to which cis-acting DNA sequences contribute to the specification of chromatin state remains incompletely understood. To address this, we have used a fission yeast sequence element (L5), known to be sufficient to nucleate heterochromatin, to establish de novo heterochromatin domains in the Schizosaccharomyces pombe genome. The resulting heterochromatin domains were queried for the presence of H3K9 di-methylation and Swi6p, both hallmarks of heterochromatin, and for levels of gene expression. We describe a major effect of genomic sequences in determining the size and extent of such de novo heterochromatin domains. Heterochromatin spreading is antagonized by the presence of genes, in a manner that can occur independent of strength of transcription. Increasing the dosage of Swi6p results in increased heterochromatin proximal to the L5 element, but does not result in an expansion of the heterochromatin domain, suggesting that in this context genomic effects are dominant over trans effects. Finally, we show that the ratio of Swi6p to H3K9 di-methylation is sequence-dependent and correlates with the extent of gene repression. Taken together, these data demonstrate that the sequence content of a genomic region plays a significant role in shaping its response to encroaching heterochromatin and suggest a role of DNA sequence in specifying chromatin state.
