Objective To scientifically and reasonably set the layout and scale of wards to optimize bed efficiency.Methods The hospital's 2022 inpatient statistical report and DRG-related data were selected,including the number of discharges,the number of actual occupied bed days,the bed utilization rate,and the number of bed turnovers.The index distribution chart was used to classify the hospital's wards into four categories,establish the bed work efficiency model and the bed output efficiency model,and introduce the CMI index for adjustment.Results 40%of the hospital's wards are located in the"efficiency"quadrant,5.3%in the"bed pressure"quadrant,28%in the"turnover"quadrant,and 26.7%in the"vacant"quadrant.The CMI-adjusted bed productivity and ward layout improved significantly,resulting in an optimal allocation of resources.Conclusion The estimation of beds'reasonable interval through bed working efficiency and bed output efficiency,and the timely bed adjustment and staff deployment in combination with the actual situation have effectively improved the operational efficiency of the hospital.
