Women in engineering, science and technology in sub-Saharan Africa: cultural attitudes, challenges, and gaps affecting clinical engineering and medical devices maintenance practices

Abstract Purpose From previous studies, we had observed that the number of biomedical engineers and technicians (BMETs) skilled in the maintenance of medical devices (MDs) were limited in sub-Saharan Africa (SSA) and that a likely parallelism existed between BME maintenance-related tasks and house chores mainly carried out by women in daily life. Our objective in carrying out this study was to understand underlying local cultural and social factors and domestic traditions interfering with the inclusion of women in the field of clinical and biomedical engineering (BME), and to identify existing gaps in opportunities for women in Engineering, Science and Technology (EST) in this region. Methods We carried out an online survey involving 51 respondents (70.6% women, 29.4% men), to investigate gender-biased and cultural perceptions of maintenance-related tasks among engineers/technologists/technicians in BME and other allied professions in SSA​. The survey was refined through focus groups and pilot tests to assess its validity, and then shared among specific associations of women in engineering and other bodies in EST, as well as some hospital communities and institutions. Results The survey brought to light evidence of prejudices against women in the society and workplace and showed that the adoption of our parallelism hypothesis has potential for increasing medical device maintenance practices in SSA hospitals. Conclusions There is an apparent need to further study the possible effects of this sociological model through leveraging local culture and domestic traditions in ways that could ultimately increase the leadership and numbers of women BMETs in SSA.

Biomedical Engineering Education in Nigeria

In the past five decades, Nigeria has witnessed a range of Biomedical Engineering (BME) and technology activities within private and public hospitals, research institutions, and a limited number of universities. These have mainly centred on the procurement, installation, and maintenance of medical equipment and devices. Trained technologists and technicians, equipped with relevant skills and certification, have primarily spearheaded these efforts. Consequently, the country has made a minimal contribution to the global knowledge base in BME research. However, academic programmes leading to degrees and dedicated research in BME have recently emerged within Nigerian universities. This article assesses the current state of BME education in the country, including the milestones achieved, ongoing challenges, and prospects for future development. It draws on a critical analysis of the existing literature on BME practices and education in Nigeria as well as the author’s informed perspective. The findings highlight that BME education in Nigeria is yet to match international standards. To further develop these programmes, it recommends that attention focus on seven key areas that have proven instrumental in the development of similar university programmes in developed nations. Strategies are also proposed to foster collaboration among universities, researchers, the health sector, and government entities that would promote interdisciplinary BME education, ultimately enhancing the healthcare delivery system, and research and development (R&D) in Nigeria.

The Circular Digital Cockpit: Towards an actionable framework for life cycle circularity assessment and decision

Digital solutions such as IoT, machine learning, big data, and simulation platforms are increasingly integrated into industrial practices but are not fully leveraged for enhancing circularity in the value chain. To address this, the Circular Digital Cockpit (CDC) framework is proposed to aid manufacturers and public authorities in transitioning towards circularity. The CDC is structured to analyze and improve organizational activities, incorporating Data Science, Digital Enterprise Architecture, and Circular Economy Strategies. It comprises two main parts. The first, "Measure, Understand, Prioritize", focuses on transforming lifecycle data into circularity indicators suitable for various organizational roles, like product and process managers. This helps in prioritizing improvement objectives both individually and organization-wide. The second part, “Act – Imagine, Simulate, Decide, Deploy –, Monitor”, guides each actor in developing and implementing actions aimed at circularity and sustainability goals. This involves assembling a global action plan and employing the Theory of Change methodology to assess and refine these actions based on their impact on circularity and sustainability. The CDC's adaptability and potential in enhancing circular practices across various industries and territorial levels are tested in diverse scenarios, including the remanufacturing of heavy vehicles, the maintenance of medical devices, and the management of bio-waste and construction waste.

Is ANTT Achievable in the Home Healthcare Setting?

At the heart of infection prevention in the home care setting is aseptic technique, a generic term for the clinical competency of ensuring asepsis during invasive clinical procedures and the maintenance of invasive medical devices. Variable terminology has resulted in confused education and clinical practice. Ambiguity has played out in all care environments, but especially in the home, where the challenge of providing effective aseptic technique is complicated by unique environmental and logistical factors. This has led some to conclude that aseptic technique is not possible in the home, or that it is not required at all in certain situations. This article challenges these assumptions and outlines the Aseptic Non Touch Technique (ANTT®) Clinical Practice Framework, that is used widely internationally. Through a thematic analysis of focus group discussions with home care nurses (n = 107) in the United Kingdom and the United States, opinions about aseptic practice in the home care setting were examined. Three main polarizing themes were identified and used to discuss theory and practice applications of aseptic technique for home healthcare nurses. Specific challenges in performing aseptic technique in home-based settings are exacerbated by ambiguity between what constitutes "clean," "aseptic," or so-called "sterile" technique, and are perpetuated by a lack of competency-based training that doesn't reflect the critical importance of aseptic technique to patient safety. Rather than continuing an endless debate about the definition of aseptic technique, ANTT has redefined aseptic technique education and clinical practice, with a comprehensive clinical practice framework and associated clinical governance better supporting patient safety.

Forecasting Repair and Maintenance Services of Medical Devices Using Support Vector Machine

Abstract Accurate prediction of product failures and the need for repair services become critical for various reasons, including understanding the warranty performance of manufacturers, defining cost-efficient repair strategies, and compliance with safety standards. The purpose of this study is to use machine learning tools to analyze several parameters crucial for achieving a robust repair service system, including the number of repairs, the time of the next repair ticket or product failure, and the time to repair. A large data set of over 530,000 repairs and maintenance of medical devices has been investigated by employing the Support Vector Machine (SVM) tool. SVM with four kernel functions is used to forecast the timing of the next failure or repair request in the system for two different products and two different failure types, namely, random failure and physical damage. Frequency analysis is also conducted to explore the product quality level based on product failure and the time to repair it. Besides, the best probability distributions are fitted for the failure count, the time between failures, and the time to repair. The results reveal the value of data analytics and machine learning tools in analyzing post-market product performance and the cost of repair and maintenance operations.

Markov chain optimization of repair and replacement decisions of medical equipment

• The study determines the optimal repair or replacement decision based on the product lifecycle data. • A Markov Decision Process (MDP) framework is proposed for optimizing repair decisions. • A dataset of medical device repair and maintenance is used to show the application of the model. • Product lifecycle data is essential for lowering repair and replacement costs. The cost of repair and maintenance of medical devices can be fairly burdensome to the healthcare industry. Healthcare providers often consider plans such as increasing in-house repairs, using multiple repair service providers, or timely replacement of devices to overcome this issue. This study aims to develop a data-driven Markov Decision Process (MDP) framework based on Discrete-Time Markov Chain (DTMC) model to optimize medical equipment repair and replacement decisions. Effective decision-making on whether to repair or replace is crucial to managing the product lifecycle cost and the costs to healthcare facilities. The study determines the optimal repair or replacement decision based on the product lifecycle data and current product failure status. It utilizes a net present value model to maximize expected value over an infinite time horizon. The study uses a dataset of 24,516 repair and maintenance records of 5,171 individual medical devices of a particular type to extract parameters needed for the optimization model. The dataset provides a rich baseline for analyzing different failures and event modes during product lifespan such as battery-related issues, random failure, preventive maintenance, and physical damage. It further quantifies the chance of moving from one product status to another. The model outcomes are discussed for a particular case. The findings reveal the most frequent reasons for failures and the most economically viable repair and replacement decision for each end-of-use device based on their current condition. Several sensitivity analyses are conducted to clarify the impact of operating revenue and warranty time on the repair or replacement.

PurposeSpecial technical issues associated with the function and maintenance of medical devices arise in intensive care units (ICUs). This study explored the level of comfort of ICU staff in dealing with selected equipment, the factors that are associated with the staff’s ease of adaptation to new technologies, and the role of technical support staff.Patients and MethodsThis is a single-center cross-sectional questionnaire-based survey that was conducted in February 2018 and targeted nurses working in the ICUs of King Saud University Medical City in Riyadh, Saudi Arabia.ResultsAmong the 297 nurses who completed the survey, almost all of the respondents (99.3%) were aware of the ICU equipment preventive maintenance program. Most of the nurses had received training on how to use infusion pumps (96.2%), cardiac monitoring systems (78.0%), and cardiac defibrillation devices (73.9%). Sixty nurses (20.2%) indicated that at least one super user was available for at least one device. About half of the staff reported one device whose user manual was available. Most nurses reported having no resources regarding updates on medical devices.ConclusionOur findings revealed an alarming need to address technical issues related to medical devices used in the ICU and to design a framework for the safe operation of medical devices based on international practices. It is necessary to empower the role of the super user and medical device clinical educator as well as to optimize communication between the national regulatory body of medical devices and healthcare providers, especially those working in acute care areas.

Анализ сервисного обслуживания медицинской техники в государственных организациях Республики Казахстан Аналитическая cправка для формирования политики

This paper presents results of overestimation of service work of medical equipment at the state organizations of the Republic of Kazakhstan. It is typical that official representatives overprice the cost of service work of medical devices, so the service of expensive equipment is carried out by unauthorized suppliers who do not have the necessary knowledge and skills. There is also deficit of financial resources between the actual need and the planned expenditures of budgetary funds for the maintenance of medical devices. There is insufficiently developed practice of training medical personnel on the basis of equipment manufacturers or an institution providing professional training in servicing relevant types of equipment. Due to this reason, there is a lack of engineers servicing medical equipment. The authors proposed recommendations for making changes to the current regulatory legal acts of the Republic of Kazakhstan regarding the scope of service maintenance of medical devices. It is recommended to create a competent center for centrally dealing with the issues of medical equipment breakdowns, as well as Implementation of a computerized maintenance management system (CMMS) for medical equipment

Medical Instrument Skill Competency in Vocational High Schools Based on Legal Rules in Indonesia

The application of electronic instrument technology to the health sector requires more detailed quality assurance and is guaranteed in the use, maintenance, repair and/or development of medical instrument devices. Improving the quality and quantity of medical instrument needs to be supported by an increase medical instrument personnel. This research was conducted to examine more about Indonesian medical/electromedical instrument personnel, specifically at vocational high school level in 2020 in an effort to overcome the challenges of the development of instrumental technology in the health sector. The lack of medical instrument personnel must be completed immediately without leaving its quality. Currently, there are regulations regarding the implementation of medical instrument education at the vocational high schools level, but vocational high schools are still constrained by regulations regarding the minimum qualifications for medical instrument education in the applicable regulations. This condition causes vocational high schools to date to have not implemented competency in medical device expertise even though it has been mapped on the spectrum of ministries. In fact, regulations serve as guarantees of operation quality, guarantee of competency criteria, guarantee of work quality, and guarantees for medical instrument personnel.

Compliance with standard precautions in inpatient healthcare settings in the Czech Republic: a cross-sectional survey.

The study evaluates compliance with declared hygienic standards carried out by healthcare professionals in clinical practice within their scope of direct patient care and the maintenance of medical tools and devices in healthcare facilities in the Czech Republic. Cross-sectional questionnaire study focused on the standards of safe health care. All 80 addressed healthcare providers were also involved in the 2018 Adverse Event Reporting System (AERS) pilot project. Responses were scored on a 6-level scale, from "always" (100 points) to "never" (0 points). The evaluation was performed according to the frequency of responses and the average index (max. 100 points). Data analysis was performed using IBM SPSS Statistics version 22 (level of significance 1% and 5%). There were statistically processed 2,016 questionnaires (100%). Most respondents stated their job classification as non-medical healthcare professionals (NHP) working at a patient's bedside (73%), physicians (16%), or other NHP (11%). As per their medical specialty, 43% of the respondents practice internal medicine, 28% surgery, 14% psychiatry, 9% long-term inpatient care, and 6% stated other fields of medicine. The lowest declared compliance was registered in the statement "I use a face mask when exposure to air-transmitted pathogens is anticipated" (rating index 80 points). The highest compliance (99.4 points) was registered in the statement: "I discard used sharp materials into sharps containers." In the surveyed healthcare facilities within the Czech Republic, overall compliance with hygiene standards is at a good level. Declared differences in compliance with hygiene standards in the selected items of the questionnaire are influenced by multiple factors. Generally, a higher level of compliance is linked to increasing age, years of practice, and a higher level of education. When comparing professional groups, a higher level of compliance with hygiene standards was registered in the NHP group.
