Surgical technology Mobile assistance systems Operating room personnel Decision support systems Thesis (MEng)--Stellenbosch University, 2023. ENGLISH ABSTRACT: Purpose. Shortage of personnel is the biggest challenge in healthcare systems worldwide. Various sectors in healthcare claim staff shortages, including the operating theatres of hospitals. To address the problem of personnel shortages, technological means are being extensively researched in both healthcare and industry, primarily in artificial intelligence, robotics, and digitalisation. The use of mobile assistance systems (MAS) – a sub-section of robotics – enables a high degree of autonomy and mobility through the area where the MAS are employed. While MAS have already been used in hospitals, applications in the operating theatre have not yet been sufficiently investigated. Nevertheless, MAS promise to relieve personnel from burdensome health, repetitive tasks, and high-stress procedures in the operating theatre. Methods. Literature reviews are conducted to obtain a comprehensive understanding of the operating theatre, MAS, operational and technical requirements, existing concepts, and frameworks for decision-support and the state-of-the-art of MAS in industry, hospitals, and operating theatres. Explorative interviews with operating theatre experts are executed to determine application areas and to evaluate their potential. Since the potential is high, the operating theatre integrated mobile assistance system decision-support is developed to support designing an application-specific MAS for the unique operating theatre domain. The verification and validation are determined to verify the 27 requirement specifications of the concept design with four MAS experts in the learning factory werk150 in Reutlingen. Further, a case study, including a workshop with a hospital manager, surgeon, and engineers, is executed to apply the concept to a real-world scenario. The case study is conducted in the operating theatre of a hospital to evaluate applicability, practicability, and usability. Results. MAS are currently not integrated into the operating theatre despite increasing demand for them. Potential application areas are administrative support, cleaning the operating theatre, equipment and furniture setup, guidance support, material management, patient management, and visualisation. In particular, MAS assistance to reduce the processing time is significant. The concept of decision-support assists in structuring the first conceptual ideas of potential applications from hospital managers or clinical personnel. Hence, the concept targets interdisciplinary perspectives from clinical decision-makers and technicians. The experts verify the requirement specifications of the concept design and highly emphasise applicability, practicability, and usability. The resulting MAS design is an all-in-one solution to assist standardised and suddenly changing material-related tasks. The MAS conducts the tasks autonomously, processes verbal commands and collaborates with personnel, navigates with vision-based guidance, and does not require an additional robotic application but includes a mini platform add-on to load single materials. The entrance to the operating theatre and the circulator corridor are critical zones in which the MAS needs to reduce its speed. The MAS is not allowed to drive inside the operating room during surgery. Conclusion. This research provides a comprehensive analysis of literature, potential-rich application areas for MAS in operating theatres, a valuable decision-support tool for designing an MAS with its unique operational and technical requirements, and implementation in a real-world scenario. AFRIKAANSE OPSOMMING: Doel. 'n Tekort aan personeel is die grootste uitdaging in gesondheidsorgstelsels wêreldwyd. Verskeie sektore in die gesondheidsorg beweer dat daar 'n tekort aan personeel, insluitend in die operasiestelsels van hospitale, is. Om die probleem van personeelstekorte aan te spreek, word tegnologiese middele wyd ondersoek in beide gesondheidsorg en die industrie, hoofsaaklik in kunsmatige intelligensie, robotika, en digitalisering. Die gebruik van mobiele bystandstelsels (MAS) - 'n sub-seksie van robotika - maak 'n hoë graad van outonomie en beweeglikheid moontlik in die gebied waar die MAS aangewend word. Terwyl MAS alreeds in hospitale gebruik is, is toepassings in die operasiestelsel nog nie voldoende ondersoek nie. Nietemin, MAS beloof om personeel te vry te stel van belastende gesondheids-, herhalende take, en hoë-streshandelinge in die operasiestelsel. Metodes. Literatuuroorsigte word onderneem om 'n omvattende begrip van die operasiestelsel, MAS, operasionele en tegniese vereistes, bestaande konsepte, en raamwerke vir besluitsteun, asook die huidige stand van MAS in die industrie, hospitale, en operasiestelsels te bekom. Verkennende onderhoude met operasiestelselkenners word uitgevoer om toepassingsgebiede te bepaal en hul potensiaal te evalueer. Aangesien die potensiaal hoog is, word die besluitsteunstelsel vir geïntegreerde mobiele bystand in die operasiestelsel ontwikkel om die ontwerp van 'n toepassingspesifieke MAS vir die unieke operasiestelsel-domein te ondersteun. Die geldigheid van die besluitsteunstelselword bepaal deur die 27 vereistespesifikasies van die konsepontwerp te verifieer met vier MAS-kenners in die leerfabriek werk150 in Reutlingen. Verder word 'n gevallestudie, insluitend 'n werkswinkel met 'n hospitaalbestuurder, chirurg, en ingenieurs, uitgevoer om die konsep in 'n werklike scenario toe te pas. Die gevallestudie word in die operasiesaal van 'n hospitaal uitgevoer om toepaslikheid, uitvoerbaarheid en bruikbaarheid te evalueer. Resultate. MAS word tans nie geïntegreer in operasiestelsels nie, ten spyte van die toenemende aanvraag vir daarvoor. Potensiële toepassingsgebiede sluit administratiewe ondersteuning, skoonmaak van die operasi-estelsel, opstel van toerusting en meubels, leidingsondersteuning, materiaalbestuur, pasiëntbestuur, en visu-alisering in. MAS-hulp om die verwerkingstyd te verminder, is veral beduidend. Die besluitsteun konsep struktureer die eerste konseptuele idees van potensiële toepassings deur hospitaalbestuurders of kliniese personeel. Dus is die konsep gerig op interdissiplinêre perspektiewe van kliniese besluitnemers en tegnici. Die kenners het die vereistespesifikasies van die voorgestelde konsep geverifieër en beklemtoon die toepaslikheid, praktiese uitvoerbaarheid, en bruikbaarheid van die voorgeselde besluitsteunkonsep. Die resultaat van die MASontwerp is 'n alles-in-een oplossing om gestandaardiseerde en skielike veranderinge in materiaalverwante take te ondersteun. Die MAS voer die take outonoom uit, verwerk verbale bevele en werk saam met personeel, navigeer met visie-gebaseerde leiding, en vereis nie 'n bykomende robottoepassing nie, maar sluit 'n miniplatvorm-byvoeging in om enkel-materiale op te laai. Die ingang na die operasiestelsel en die omloopgang is kritieke sones waarbinne die MAS sy spoed moet verminder. Die MAS mag nie binne die operasiekamer gedurende chirurgie beweeg nie. Gevolgtrekking. Hierdie navorsing bied 'n omvattende ontleding van literatuur, potensiaal-ryke toepassingsgebiede vir MAS in operasiestelsels, 'n waardevolle besluitsteunstelsel vir die ontwerp van 'n MAS met sy unieke operasionele en tegniese vereistes, en implementering in 'n werklike scenario.
