Abstract:This study is performed in Røros Sykehus, which is situated in the little old mining town Røros in Norway. The goal of this research was to: “Get an overview of the current performance of the OR department of Røros Sykehus and determine bottlenecks which can be changed to improve the current situation.” Background Røros Sykehus has been on the verge of doom 22 times in its history. In 2010 the hospital changed their case mix and built new ORs. At the moment there is a negative profitability and the projection is that by the end of the year 2011 there is a deficit. The head of department asked us to analyse the OR department on their performance and whether improvements would be possible. The head of department also wanted to know what the maximum possible number of patients is which can be operated and how he could get an insight in the current performance. Research approach This study is done by observing the processes in Røros Sykehus during our stay. We analysed the historic data from September 2010 to the start of June 2011. We made an analysis of the context, the control and the performance. This yielded the first half of the research question. Furthermore we analysed the data for bottlenecks. We build a simulation model is to represent the current situation and to simulate improvements. In the simulations we test what would happen when time per surgery is reduced by 15 and 19 minutes. Furthermore we give recommendations on how to achieve this reduction in time. Results From the performance analysis we can conclude the following performances in utilization rate: Specialty Utilization rate n σ 2 Orthopaedics 72,6% 104 16,3% 1 Orthopaedic 86,1% 124 12,1% Gynaecology 76,4% 16 7,7% Oral surgery 67,5% 28 11,1% ENT surgery 57,7% 24 12,4% Furthermore the OR start time was off schedule by on average 20 minutes with the median of 17 minutes. The changeover time varied on average between 19 and 27 minutes. Furthermore 73% of the surgeries ended within time. In the simulation study we concluded that reducing 15 minutes per operation would be possible and would increase the number of operated patients per year from 1720 to at least 1940. 19 minutes of improvement in surgery or changeover time yielded an even greater number of possible patients. Conclusion From the simulation, observations and the historic data we can conclude that there is room for improvement in Røros Sykehus and that the improvement lies within reach. The alignment of work processes and the use of empty ORs should yield the predicted improvements.
