Safety in the Operating Theatre | a Multi Factor Approach for Patients and Teams
No full textDue to the advances in high-tech technology in the operating theatre, the increased number of persons involved, and the increased complexity of surgical procedures, medical errors are inflicted. To answer the main question: How to improve patient safety in the operating theatre during surgery? this thesis is split into three parts. Part A focuses on the processes concerning ‘planning, acting/ performing and recording’ surgical procedures. Currently, no surgical protocol uniformity exists and most operative notes are still dictated postoperatively. Operative notes are sometimes not written according to the guidelines for operative note writing, are subjective, and do not fully correspond to the actual events observed in the video recordings of that particular procedure. Part B focuses on the implementation of a Time Out Procedure plus Debriefing (TOPplus). Results show that operating team members hold different perceptions of communication, teamwork and situation awareness. Designing TOPplus by means of the user-centred participatory design approach, in combination with the context-specific design principles, proves advantageous for implementing the procedures and acts as a catalyst for related patient safety initiatives. Part C focuses on improving the working conditions of the operating team. During surgery problems are encountered within the sensorial, cognitive, physical, and environmental domain. Surgeons performing minimally invasive surgery experience physical discomfort in mainly neck, shoulder, and back. Although the importance of ergonomics is recognised, only few surgeons are aware of general ergonomic guidelines to improve their working conditions. Finally, product evaluation of two types of surgical lights shows that specific disciplines require different lights.Industrial DesignIndustrial Design Engineerin
Mind the Gap: Designing Sustainable Healthcare for Humanitarian Aid
No full textHumanitarian emergencies like the natural disasters in Nepal, Haiti or Pakistan or the thousands of refugees and internally displaced people fleeing from long-term conflict in Syria or South Sudan are likely to increase. To provide healthcare assistance, international humanitarian organizations transfer a variety of medical equipment and staff to an affected area with the purpose of reinforcing or even replacing disrupted healthcare activities. The replacement system they transfer is usually of a high quality standard, and therefore not suitable to be transported, used, maintained and disposed in austere and low-resource settings. In comparison to providing food or shelter assistance, providing safe healthcare in such situations is particularly challenging due to the level of medical and technical expertise required. In this thesis, the unsustainability of the transfer process of medical equipment in humanitarian emergencies is addressed by describing and analysing how the transfer takes place. Furthermore, two field studies in Indonesia and Haiti are presented. The humanitarian sector is increasingly challenged by the need to become more efficient and competitive. The recent adoption of the ‘humanitarian innovation’ concept, defined by words like “sustainable”, “beneficiaries”, and “long-term” brings an encouraging view ahead towards a more sustainable transfer of medical equipment. A combination of field, interview and literature studies, led to the development of a systems design approach to the transfer of medical equipment in humanitarian emergencies that challenges the field of medical design engineering to broaden its scope and disciplinary boundaries.Design EngineeringIndustrial Design Engineerin
Towards increased global availability of surgical equipment
No full textThe need for surgery in low- and middle-income countries (LMICs) is tremendous; more people die from treatable surgical conditions than from tuberculosis, malaria and HIV put together. A crucial barrier to surgical care in LMICs is the limited availability of surgical equipment, which results in delays and cancellations of surgeries on a daily basis. The overall aim of this thesis is to study the use of surgical equipment in LMICs, in order to understand how to increase global availability of surgical equipment in the future. One of the strategies that is researched more thoroughly, is the design of context-specific surgical equipment. As many areas in Africa feel the burden of limited access to surgery, we have used hospitals in Africa as a case study, with a main focus on Kenya.Medical Instruments & Bio-Inspired Technolog

The effect of chemical cleaning on mechanical properties of three- dimensional printed polylactic acid
No full textThree-dimensional (3D) printing may be a solution to shortages of equipment and spare parts in the healthcare sector of low- and middle-income countries (LMICs). Polylactic acid (PLA) for 3D printing is widely available and biocompatible, but there is a gap in knowledge concerning its compatibility with chemical disinfectants. In this study, 3D-printed PLA tensile samples were created with six different printer settings. Each of these six batches consisted of five sets with five or six samples. The first set remained untreated, the others were soaked in Cidex OPA or in a chlorine solution. These were applied for seven consecutive days or in 25 short cycles. All samples were weighed before and after treatment and subjected to a tensile test. Results showed that a third of the treatments led to an increase of the median weight with a maximum of 8.3%, however, the samples with the best surface quality did not change. The median strength increase was 12.5% and the largest decrease was 8.8%. The median stiffness decreased 3.6% in one set and increased in three others up to 13.6%. When 3D printing PLA medical tools, surface porosity must be minimized to prevent transfer of disinfectants to people. The wide variability of mechanical properties due to 3D printing itself and as a consequence of disinfection must be considered when designing medical tools by selecting appropriate printer settings. If these conditions are met, reusing 3D-printed PLA medical tools seems safe from a mechanical point of view.Green Open Access added to TU Delft Institutional Repository ‘You share, we take care!’ – Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Medical Instruments & Bio-Inspired TechnologyDesign for Sustainabilit

Systems design perspective of healthcare provision in humanitarian aid
No full textThis study focuses on the role of Systems Design in addressing the challenges of healthcare provision by international emergency relief organizations in developing countries. More specifically the challenges related to the safety and performance of medical equipment that is transferred in the aftermath of a humanitarian crisis. The aim of this paper is to describe the transfer of medical equipment and its associated challenges from a systems perspective and to reflect on the value of Systems Design as an approach to humanitarian innovation, addressing the identified systemic challenges. The concepts of Human Factors and Ergonomics, and Product-Service Systems will be presented as valuable contributions to support designers in handling a larger degree of complexity throughout the design process and to support them to make informed choices regarding this particular context.neoDesign for SustainabilityMedical Instruments & Bio-Inspired Technolog
Equipment for essential surgical care in 9 countries across Africa: availability, barriers and need for novel design
No full textShortages of medical equipment in low-and-middle income countries (LMICs) have been found by several previous studies that assessed surgical capacity. To increase surgical capacity, there is a need to identify the availability of specific types of surgical equipment on a local, regional and national level. A survey was conducted among surgeons attending the annual meeting of the College Of Surgeons of East, Central and Southern Africa (COSECSA) in December 2016. General information of the facilities, availability of surgical equipment, reasons for limited availability, daily usage of equipment and equipment that could benefit from redesign were assessed. Forty-two respondents participated in this study, representing 33 individual healthcare facilities (14 public referrals, 9 public district and 10 private (for-profit and non-profit)). The respondents worked in 9 countries in East, Central, Western and Southern Africa. A deficiency in availability of basic surgical equipment was found, especially in public district hospitals. Electrosurgical units, endoscopes, defibrillators, infusions pumps and electrocardiogram monitors were of limited availability. Reasons indicated for this limited availability were: no need, too costly, no training, no disposables and no repair. Lack of maintenance and old/overused equipment were identified as major reasons for failure of equipment. Equipment that could benefit from redesign were for example: electrosurgical units, laparoscopic equipment and theatre lights. Availability of surgical equipment should be increased, especially in public district hospitals. Novel context appropriate redesign that is adapted to fit the context in LMICs could decrease the barriers to availability and to failure of surgical equipment.Medical Instruments & Bio-Inspired Technolog
Roadmap for design of surgical equipment for safe surgery worldwide
No full textSafe and affordable surgery is not accessible for five billion people when they need it. Multiple surgical capacity studies have shown that hospitals in low-And-middle income countries do not have complete coverage of basic surgical equipment such as, theatre lights, anesthesia machines and electro surgical units. Currently, almost all equipment is designed and manufactured with a main focus on the context in high income countries. The context in low-And-middle income countries in which surgical equipment is used, differs from high income countries, especially in terms of financial resources and access to maintenance, spare parts and consumables. The aim of this study is to present a roadmap for design of surgical equipment for worldwide use. The roadmap consists of four phases: before the start of a design project a clear need for certain surgical equipment should be identified (Phase 0). During Phase 1 the context should be researched thoroughly by determining the barriers encountered by patients to surgical care, the structure of the health care system and if the aspects required for safe surgery are in place. In Phase 2 the implementation strategy and design requirements should be determined and in phase 3 prototyping starts in close interaction with local end-users. We believe that designers should strive for design that is of the same quality and complies with the same safety regulations as equipment designed for HICs. In this way user and patient safety can be assured in any setting worldwide. And we advocate for surgical equipment that fits the context optimally and that will be applicable in comparable settings globally.Green Open Access added to TU Delft Institutional Repository ‘You share, we take care!’ – Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Medical Instruments & Bio-Inspired Technolog
