Implementation Of Lean And Six Sigma Methodologies To Improve The Operations And Efficiencies Of An Inpatient Pharmacy, Brian Ricks
Medical Engineering Theses
Reducing overhead costs and eliminating process waste are important aspects of any successful organization. Hospital processes are frequently interconnected, with many exchanges of both materials and information between departments. The Inpatient Pharmacy, a key component of any hospital, has hundreds of interactions between departments on any given day, and many processes see the pharmacy acting as producers, consumers, and transporters of goods throughout the hospital. Such a varied role provides broad opportunities for process improvement. Within the broader manufacturing world, the philosophies of Lean and Six Sigma have helped many companies increase their process efficiencies, reduce costs, and increase quality. …
A Novel Electroconductive Nanofibrous Scaffold For Bone Regeneration, Mitchell Kenter
A Novel Electroconductive Nanofibrous Scaffold For Bone Regeneration, Mitchell Kenter
Medical Engineering Theses
The goal of this study was to develop a biodegradable and conductive scaffold to mimic the piezoelectric properties of bone and the architecture of the extracellular matrix. Poly(3,4- ethylenedioxythiophene) (PEDOT) is a conductive polymer of great interest in tissue engineering due to excellent electrical stability and biocompatibility. To enhance its conductivity, dopants such as dimethyl sulfoxide (DMSO) can be added. Engineered graphene oxide (GO) can also be introduced as oxidant to enhance conductivity and mechanical properties. PEDOT nanocomposites were synthesized by oxidative polymerization of 3, 4-Etylenedioxythiophene monomer (EDOT) in the presence of GO, DMSO, ferric chloride and various solvents. The …
Evaluation Of Swinging Performance: Quantifying A Surgical Mallet Device, Benjamin M. Schintgen
Evaluation Of Swinging Performance: Quantifying A Surgical Mallet Device, Benjamin M. Schintgen
Medical Engineering Theses
One of the steps of performing a total hip arthroplasty (THA) is to broach a femoral implant down the femoral canal to add stability down the length of the femur. Broaching consists of surgeons impacting the femoral implant multiple times down the trabecular bone of the femur in increasing size until the implant is sized to either within 3mm of fill of the bone cavity or within surgeon discretion. Fracture of the bone can be caused if the force of impact is too great. Furthermore, surgeons do not know how much force they generate when using an impaction device, such …
A Comparative Analysis On The Precision Of The “Push/Thumb Test” Conducted During Orthopedic Procedures, Avery Waldron
A Comparative Analysis On The Precision Of The “Push/Thumb Test” Conducted During Orthopedic Procedures, Avery Waldron
Medical Engineering Theses
This study explored the precision of the “push/thumb” test conducted during orthopedic joint replacement. Participants were eight orthopedic residents ranging from three to five years of experience. Three sets of six simulated bones were 3D printed at varying density to mimic the variation surgeons may experience from patients in real life. Bone sets were randomized for two experiments. Both experiments had subjects conduct the “push/thumb” test on the simulated bone sets and binary responses were recorded. For experiment 2, subjects were provided a reference tool to utilize during the “push/thumb” test to determine if said tool had a positive impact …
Patella Resection In Total Knee Arthroplasty: An Analytical Comparison Of Three Techniques, Kelsey Cushway
Patella Resection In Total Knee Arthroplasty: An Analytical Comparison Of Three Techniques, Kelsey Cushway
Medical Engineering Theses
Patella resection, as a routine component of TKA, can be both difficult to plan and difficult to execute. The primary purpose of this study was to evaluate the repeatability of three unique patellar resection techniques used in total knee arthroplasty. The secondary purpose of this study was to establish whether different surgical techniques were able to reproduce preoperative plans made by each surgeon. We used radiographic measurements to evaluate patellar thickness and patellar cut angle preoperatively and postoperatively. Three techniques (45 cases in total) were evaluated, revealing qualitative differences between surgical techniques and significant quantitative differences between average patellar thickness …
