Leave a reply

This capstone project took approximately 9 months to complete from initial planning stages through final delivery and presentation. While every capstone is different based on the specific goals, challenges, and team dynamics, here is a breakdown of the major stages and approximate time spent on each for this particular project:

Planning and Proposal Development (1 month) – The first step was determining a scope and focus for the project that would provide value and learning while also being achievable within the timeframe and resource constraints. This involved researching potential topics, identifying key stakeholders, assessing feasibility, and outlining a preliminary plan and timeline. A formal proposal was then written, reviewed, and approved to gain official project authorization and secure needed resources/funding.

Requirements Gathering and Analysis (2 months) – With the proposal approved, we moved into more in-depth research, stakeholder interviews, process documentation, data collection, and competitive analysis to fully understand requirements. User needs, success metrics, constraints, risks, and opportunities were explored. Functional and non-functional requirements were logically organized, documented, and validated with stakeholders. Edge cases, assumptions, and open questions were identified to guide subsequent development phases.

Design and Architecture (2 months) – Leveraging the detailed requirements analysis, we began designing solutions at both a high level (system architecture) and low level (detailed design). Major architectural decisions were made regarding technologies, frameworks, patterns, interfaces, scalability, security etc. User flows, information architectures, APIs, databases, reports and more were designed. Technical specifications and prototypes helped validate designs with stakeholders prior to development. Resources and schedules were revised as needed based on validated designs.

Development and Testing (3 months) – With designs complete and approved, development commenced according to an iterative approach. Small increments of functionality were built based on priority. Rigorous unit, integration, system, performance, security and user acceptance testing were conducted on each increment. Documentation, configuration management and quality assurance processes were followed. Frequent stakeholder demos and feedback sessions ensured work remained on track. Bugs were addressed during development sprints rather than through separate testing phases.

Implementation and Deployment (1 month) – Once development and testing deemed the system ready, focus shifted to deployment preparation. Deployment, configuration, data migration and cut-over plans were finalized. User training materials and support processes were established. The system underwent pre-deployment testing and dry runs prior to any production rollout. With stakeholder sign-off, the project was then officially implemented and transitioned operations over a planned rollout period.

Documentation and Closure (1 month) – The final phase involved documenting all processes, designs, configurations, test cases/results, issues/resolutions, and lessons learned from the project. As-built configurations and a full operations manual handed the system/process over to its organizational owners and support teams. Releases were packaged for reproducibility. Stakeholders provided final acceptance. Resources were reallocated as the project ended and preparations commenced for follow-on initiatives identified during this project. Impacts to the organization were assessed and communication disseminated regarding next steps for continuous improvement and benefits realization.

In total, with allowances for iterative development cycles, stakeholder feedback periods, testing timeframes, deployment preparation, documentation and closure, this particular capstone took approximately 9 months from initial planning through final delivery and acceptance. Of course, real-world projects regularly involve unforeseen challenges that impact schedules. This breakdown aims to provide a transparent view into typical time investments across the life cycle of a substantive project with educationally valuable goals completed through dedicated collaborative effort. Proper planning, analysis, design care, testing rigor and management focus helped maintain alignment to scope and timeline for successful completion of learning objectives through practical work.

DO YOU HAVE ANY ADVICE ON HOW TO SELECT A TOPIC FOR A CAPSTONE PROJECT THAT ALIGNS WITH MY INTERESTS

Leave a reply

Choosing a topic for your capstone project that aligns with your personal interests and passions is key to remaining motivated throughout the intense research and writing process. With so many potential options it can be difficult to narrow down exactly the right focus. The following steps can help guide you to select a topic that you will find truly engaging and fulfilling.

Start by brainstorming a wide list of potential topics without censoring any ideas no matter how broad or obscure they may seem. Write down everything even remotely related to your major field of study or other academic interests that spark your curiosity. Reviewing hobbies, extracurriculars, jobs/internships, areas of the world, people, or time periods that fascinate you can spark new topic ideas. At this stage, go for quantity of ideas rather than worrying if each one is too big or narrow in scope.

Once you have an extensive list, analyze it for common themes or connections between certain topics. Group related ideas together into overarching categories to help narrow the focus. For example, if you enjoy history and have interests in both ancient Rome and Victorian London, you could potentially design a comparative study of those two time periods. Identifying logical similarities between broad topics can lead to more defined potential research areas or questions.

Assess each general topic area for feasibility within the parameters of a capstone project. Consider if there is enough available research on the subject to support extensive analysis within the required timeframe and page limit. You’ll want a topic that has depth and breadth of existing literature without being too vast. Checking with your academic advisor, librarians, and even reviewing bibliographies of previous students’ projects can help gauge feasibility. Very novel topics with little previous work carry more risk of not having adequate research to draw meaningful conclusions.

Evaluate your topic ideas based on how intrinsically engaging and inspiring you find the subject matter. A compelling personal passion will sustain the long hours of research required. Consider which topics continue interesting you the more you think about them versus ones that seem exciting in the moment but hold less fascination over time. Reflect on topics that make you want to keep learning more versus feeling like checking them off a list. Intrinsic excitement, not extrinsic goals or expectations, should drive topic selection.

Review your list of narrowed topics and consider real-world applications or ways any of the potential areas could create positive change. Having a sense of purpose behind your work can make the process even more valuable and rewarding. For example, a healthcare administration student passionate about mental health may choose to analyze ways to improve access to counseling services on college campuses. The potential for applied research outcomes to benefit society can further distinguish inspiring options.

As appropriate for your field of study, evaluate topics that may have career relevance in the future. While interest should be the primary driver, considering long-term implications can add practical value to your work. For example, an engineering student aiming for machine learning roles post-graduation may opt for a capstone proposal related to predictive data analytics applications. Career direction need not define the topic, but relevance can enhance your professional portfolio.

Once you have a shortlist of two to three options that meet criteria for feasibility, engagement, and application, discuss them candidly with your capstone instructor and academic advisor. Unbiased experts can provide insightful perspectives on logistics, literature quality, and strengths or limitations of each idea. Their questions may also uncover new angles to consider that had not yet occurred to you. Incorporating this critical feedback before deciding allows refining potentially promising concepts into the optimal research focus.

With open communication between yourself, instructors, and librarians, as well as an unwavering commitment to personal interests as the driver, following this exploratory process will lead to selecting a capstone topic that aligns passion and purpose. Choosing the right focus anchored intrinsically by what inspires your curiosity establishes an engaged mindset crucial to completing a compelling and impactful final research project. With this guidance, you are empowered to craft impactful work through diligent pursuit of your genuine academic passions.

Development of an Upper Extremity Exoskeleton to Aid in Rehabilitation:

A team of students designed and built a robotic exoskeleton device to be worn over the arm and hand to assist in rehabilitation therapy for patients recovering from injuries such as strokes. The exoskeleton contained sensors to monitor the patient’s movements and provided assisted motions to help them regain range of motion and motor control abilities in a safe manner. It could be adjusted for different therapy exercises and tracked progress over time. The students had to research rehabilitation needs, design the mechanical components, implement control systems using motors and software, perform safety and usability testing, and develop manufacturing and assembly plans to demonstrate a potentially commercializable medical device.

Embedded Monitoring System for Neonatal Care:

Another group of students developed a non-invasive embedded monitoring system for use in the neonatal intensive care unit (NICU) to continuously track vital signs of premature infants without needing frequent disruptions to attach wired sensors. They designed wearable multi-sensor modules containing temperature, heart rate, respiration rate and oxygen saturation sensors that wirelessly transmitted data to a central station. Software was programmed to sound alarms for any unstable readings. Prototypes were tested on newborn infant simulators and feedback was gathered from NICU nurses. Regulations for medical devices were researched to outline pathways for FDA approval.

3D Printed Implants for Craniofacial Reconstruction:

In this project, biomedical engineering students partnered with facial trauma surgeons to address the need for custom implants used in complex craniofacial reconstruction surgeries. They developed a workflow using computer aided design (CAD) software and 3D printing technology to create patient-specific implants based on CT scans. Material properties of polymers and metals were analyzed to select appropriate biomaterials. Surgical planning, sterile manufacturing and regulatory issues were considered. Working prototypes of mandible, orbital and calvaria implants were fabricated and their precision-fit was verified. Collaboration continued with surgeons to refine the process and pursue clinical studies.

Biosensor for Detecting Bed sores:

Bedsores, or pressure ulcers, are a serious medical complication for patients confined to beds for extended periods. A team of students designed a flexible biosensor system that could be integrated into beds and mattresses to noninvasively monitor pressures at multiple surface points on a patient’s body in real-time. Different sensor technologies were tested and a capacitive sensor array was selected for its conformability. A microcontroller collected pressure maps which were analyzed using algorithms to detect pressures exceeding tolerance limits that pose risk of sores. Notifications were sent to caregivers’ mobile devices. Clinical feedback helped refine sensor placement and data visualization.

MRI-Compatible Robotic Biopsy Device:

Magnetic resonance imaging (MRI) provides excellent soft tissue contrast for diagnosing cancers, but current biopsy procedures require removing the patient from the scanner for needle placement. A group of students sought to address this limitation by designing a robotic biopsy device that could accurately insert biopsy needles under MRI guidance without interfering with the scanner’s magnet. They integrated non-ferrous actuators, piezoelectric motors and plastic gears into an MRI-safe mechanical design. Image processing and robot kinematics were used to precisely register needle positions from MRI images. Rigorous testing was performed to ensure no artifacts or distortions in images. Collaboration continued with radiologists to define clinical workflows and identify any remaining technical hurdles prior to pursuing FDA clearance.

This covers a sampling of some ambitious biomedical engineering capstone projects undertaken by students that involved developing real medical devices, technologies and solutions to address diverse clinical needs. The projects required integrating knowledge of human anatomy and physiology, materials selection, engineering design, manufacturing, regulations, and collaborating with medical experts. The level of innovation demonstrated in developing functional prototypes that advanced healthcare reflects the interdisciplinary training biomedical engineers receive to apply engineering principles for improving human health.

CAN YOU PROVIDE EXAMPLES OF QUALITY IMPROVEMENT CAPSTONE PROJECTS THAT HAVE BEEN SUCCESSFUL IN REDUCING HOSPITAL ACQUIRED INFECTIONS

Leave a reply

Hospital acquired infections, also known as healthcare-associated infections (HAIs), are a significant issue that impacts patient outcomes and increases healthcare costs. Implementing quality improvement projects focused on evidence-based practices to reduce HAIs has been shown to be an effective way for hospitals and healthcare workers to enhance patient safety. Here are some examples of successful capstone projects that have made a meaningful impact in reducing various types of hospital acquired infections:

One notable project took place at an academic medical center and focused on reducing central line-associated bloodstream infections (CLABSI) in the intensive care unit (ICU). CLABSIs occur when bacteria or viruses enter the bloodstream through a central line catheter. This project used the Model for Improvement framework to test changes. Interventions implemented included adopting a maximal sterile barrier during central line insertion, using chlorhexidine for skin antisepsis, and focusing on prompt removal of unnecessary lines. Compliance with best practices was tracked and deficiencies were addressed. After 12 months, the medical ICU saw a 65% reduction in CLABSI rates from a baseline of 3.7 infections per 1,000 line days to 1.3 infections. This reduction equated to 17 avoided infections and an estimated cost savings of $514,000 for the hospital.

Another successful capstone quality improvement project centered around reducing catheter-associated urinary tract infections (CAUTIs) in a surgical ICU. CAUTIs develop when bacteria enter the urinary tract through a catheter. The project team established evidence-based practices for catheter insertion and maintenance, including use of aseptic technique and sterile equipment during insertion, securing catheters properly after insertion, and only using catheters when necessary as indicated by daily reviews. Educational programming was provided to nurses. Visual aids served as daily reminders. Within 6 months of implementing the changes, monthly CAUTI rates dropped from a baseline of 2.6 per 1,000 catheter days to zero infections, representing a 100% reduction. An estimated 20 avoided infections resulted in cost savings of $400,000 for the hospital.

A capstone project at a community hospital targeted reducing ventilator-associated pneumonia (VAP) in its medical ICU. VAP occurs when bacteria enter the lungs through an endotracheal breathing tube in patients on mechanical ventilation. The core project team developed a multidisciplinary VAP bundle checklist and instituted “VAP champions” – nurses trained to serve as expert resources on VAP prevention. Education focused on maintaining the head of the bed at 30 degrees or higher, oral care with chlorhexidine, and ensuring peptic ulcer disease prophylaxis. Process measures showed near perfect compliance with the bundle elements. After 6 months, the VAP rate dropped from a baseline of 3.3 per 1,000 ventilator days to 1.7, representing almost a 50% reduction. An estimated 10 VAPs were prevented, saving the hospital approximately $300,000.

Another successful quality improvement capstone took place at a large tertiary care hospital and focused on reducing surgical site infections (SSIs) specifically after coronary artery bypass graft (CABG) surgery. SSIs occur when bacteria enter through an incision made during surgery. Best practices targeted in the project included pre-operative chlorhexidine showers or wipes for patients, appropriate antibiotic prophylaxis timing and selection, intra-operative normothermia maintenance, glucose control, wound protection, and smoking cessation support. educational in-services and visual prompts reinforced the changes. Over 18 months, compliance with all SSI prevention practices improved significantly from a baseline average of 65% to 95%. Simultaneously, the CABG SSI rate declined by 50%, from 2.5% of patients to 1.2%. This reduction meant 19 fewer infections annually and an estimated cost avoidance exceeding $500,000.

As demonstrated through these illustrative capstone quality improvement projects, multi-pronged, evidence-based approaches focused on consistent adherence to best practices can meaningfully reduce hospital acquired infection rates. Sustained reductions in CLABSI, CAUTI, VAP, and SSIs each lead to improved patient outcomes and substantial cost savings. A culture of safety, staff education, visual reminders, consistent leadership support, and multidisciplinary involvement all contributed to success. With applied efforts to optimize evidence-based care, hospitals can enhance quality and safety for patients through effective measures targeting the reduction of preventable HAIs.
