This study aims to develop the Building Information Modeling, BIM, system that enables simulations based on multiple fit between variety of floor plan types and management types in the facility planning, programming, design, and management of hospital wards. In this paper floor plan types of a dispersed nursing base type and a circular corridor type were focused and management types regarding patient placement and nursing travel distance were considered.
The case of the dispersed nursing base floor type consisted of four bed rooms and single bed room, which is still quite common in Japan, whereas the circular corridor floor plan type used only single bed rooms, which is still unique. When patient bed rooms are placed along the corridor, the placement of four single rooms requires the double corridor length compared to the placement of one four bed room. Thus, a unit hall scheme was introduced in the case studied ward floor plan where five single rooms share same unit hall functioning as a one five bed room as a whole.
The management research topic included the differences in the nursing system, patient duty allocation, teaming concept, etc. The paper also refers to the topic of Partnership Nursing System, PNS, in which a pair of two nurses conducts the duty as an equal partner. The analysis looked into the level of equality from the movement distances of two nurses.
The nursing travel survey was conducted in four wards of two hospitals to investigate the relationship between nursing activities and the number of visits to patient rooms. The conventional time study method was used where an investigator followed each nurse to record time, from and to locations, tasks, and goods carried. The factors influencing nursing travel distance and patient placements were analyzed including the nursing necessity index based on seriousness of patients’ illness.
The simulations were carried out to make predictions with optimal and inappropriate versions of patient placements using genetic algorithm, GA. The program was written using Python 3.7 applied on Autodesk Revit as BIM system through Dynamo as Visual Programming Language, VPL.
As the result of these simulations, various fit between the floor type and management type were clarified including the phenomenon that the difference in calculated nursing travel distance was small in the circular corridor floor plan type because the distance between the staff station and patient bed rooms was small under different conditions of patient placements. Also, the equality in PNS was confirmed.
