3D Printed N-95 Masks During the COVID-19 Pandemic: Lessons Learned.

Early in 2020, the pandemic resulted in an enormous demand for personal protective equipment (PPE), which consists of face masks, face shields, respirators, and gowns. At our institution, at the request of hospital administration, the Lifespan 3D Printing Laboratory spearheaded an initiative to produce reusable N95 masks for use in the hospital setting. Through this article, we seek to detail our experience designing and 3D printing an N95 mask, highlighting the most important lessons learned throughout the process. Foremost among these, we were successful in producing a non-commercial N95 alternative mask which could be used in an era when N95 materials were extremely limited in supply. We identified five key lessons related to design software, 3D printed material airtightness, breathability and humidity dispersal, and ability for communication. By sharing our experience and the most valuable lessons we learned through this process, we hope to provide a helpful foundation for future 3D-printed N95 endeavors.

Changes in Academic Plastic Surgery Programs During the COVID-19 Pandemic.

BACKGROUND: The COVID-19 pandemic has presented unprecedented challenges for surgical teaching programs, as operating rooms closed and resources were redirected for patient care. As a result, both educational challenges and opportunities emerged. The objective of this study was to assess the changes used by plastic surgery programs as a result of the pandemic. METHODS: A 34-question American Council of Academic Plastic Surgeons-approved survey was distributed on April 29, 2020, to attendings in academic plastic surgery programs in the United States. Variables were controlled whenever multiple attending responses were submitted from the same program. RESULTS: A total of 113 attendings, including 30 (27.8%) program directors, responded to the survey. Most respondents were located in the northeast (41.4%). The average percentage of elective case volume was 23% of pre-COVID states. Those who reported a decrease in emergent surgical case volume (55.2%) estimated it to be at an average of 45% of the normal. Almost all the respondents (95.6%) agreed that they were working fewer hours than usual, and 40.9% of those reported a decrease of more than 20 hours per week of work. Most attendings (82.1%) also reported a decrease in their monthly salary. The percentage projected current salary compared with normal was 85%. CONCLUSIONS: Our survey data suggest that academic plastic surgery programs have had impactful changes to their operative and educational schedules, teaching, revenue, and patient care. The data described in this study could be used as a baseline for future pandemics affecting plastic surgery programs to help strategize their operational and educational structures.

The Impact of the COVID-19 Pandemic on Plastic Surgery Consultations in the Emergency Department.

Stay-at-Home (SAH) orders implemented in the United States to combat COVID-19 had a significant impact on health care delivery for patients with all conditions. In this study, we examined the effect SAH orders had on the Emergency Department (ED) consultation volume, injury patterns, and treatment of patients managed by our plastic surgery service. METHODS: In Rhode Island, SAH orders were instituted from March 28, 2020, to June 30, 2020. A retrospective chart review of patients presenting to our Level-1 academic medical center was performed. Patient demographics, types of injuries, and need for treatment in the ED or operating room (OR) were collected. Tests of significance were conducted using a comparison group spanning the same time period, in 2019. RESULTS: There was a 36% decrease in ED consultations to plastic surgery during SAH orders when compared with those in 2019. No observed differences were noted in patient demographics between time periods. There were significant increases in the proportions of hand injuries secondary to power tools and facial injuries secondary to falls. No observed differences were identified in injury severity and need for either operating-room interventions or ED interventions for patients seen in consultation during SAH orders. CONCLUSIONS: SAH orders resulted in a decreased volume of plastic surgery consults in the ED but did not alter patient demographics, injury severity, or need for procedural interventions. There was a 2.9% positivity rate for COVID-19 for asymptomatic patients presenting in the ED with primary hand and facial injuries.

A 3-Dimensional-Printed Hand Model for Home-Based Acquisition of Fracture Fixation Skills Without Fluoroscopy.

OBJECTIVE: To design a low cost ($40), realistic and fluoroscopy-free percutaneous Kirschner wire hand fracture fixation training instrument kit for home-based skill acquisition during the COVID-19 pandemic. DESIGN: A 3D-printed hand was designed from a computed tomography scan of a healthy hand. These data were used to create replaceable hand and wrist bones and reusable silicone molds for a replica of the soft tissue envelope. The model is currently being integrated into the simulation curriculum at 2 integrated plastic surgery residency programs for training in percutaneous wire fixation of hand fractures. SETTING: Brown University, Warren Alpert Medical School of Brown University. Department of Surgery, Division of Plastic and Reconstructive Surgery. Large academic quaternary referral institution. Yale University, Yale School of Medicine. Department of Surgery, Division of Plastic and Reconstructive Surgery. Large academic quaternary referral institution. PARTICIPANTS: PGY 1-4 plastic surgery residents preparing to meet ACGME Accreditation for Graduate Medical Education hand surgery specific milestones. RESULTS: A realistic and durable 3D model with interchangeable bones allows trainees to practice the key motor skills necessary for successful fixation of hand and wrist fractures with K-wires in a home-based setting. CONCLUSIONS: A low cost, realistic and durable 3D hand model with interchangeable bones allows easy integration into any home-based hand surgery curriculum. With 3D printers and programming becoming more prevalent and affordable, such models offer a means of low-cost and safe instruction of residents in fracture fixation with no harm to patients.
