Introduction – The concept of takt time is a concept facilitating consumer demand. Takt time is "available production time divided by the level of consumer demand". Takt time is an ideal production rate for each operation. The achievements in the field of health services, especially outpatient, have been documented by a number of hospitals. Bay Medical Center (BMC) reported a reduction in outpatient queue time up to 70%, in line with the increase in revenues of up to $200,000 per year, at this hospital with 413 rooms. Stanford Medical Center reported an increase in capacity up to 75% with additional revenue up to $1.5 million. Virginia Mason Medical Center is able to reduce patient queue time up to 14% and increase the number of patients treated up to 57%.

Methodology – This research evaluated the utilization of specialist outpatient clinic by calculating takt time. After that, a number of waste reduction efforts were carried out. Performance evaluation was then undertaken by examining the documents reporting of medical records and the results of financial audit. The time compared was between baseline time in 2013 and the implementation time that was 2014.

Results - The results from all these interventions were the increase in operational time by 15,000 minutes from 32,520 to 47,520 minutes or by 46%. It is accompanied by efficiency at all of the waiting time. There was a reduction in patient waiting time by 40 minutes. Registration time decreased by 9 minutes (75%), while the doctor's practice time that was originally 38 minutes, decreased by 37%. Drug taking time decreased 13 minutes (50%) while the payment time originally 7 minutes, decreased by 57%. That observed that there was an increased revenue between 2013 and 2014. In 2013, the revenue was IDR9.61 billion. In 2014 there was an increase of IDR 13.01 billion. Meanwhile, the total revenue of the hospital was amounted to IDR 54.07 billion in 2013. In 2014 it increased as much as IDR 16.10 billion.

Discussion - The results show that the application of Lean, particularly takt time method, can be applied in the hospital. This result is obtained by removing waste while maintaining the work safety and limitations of existing costs. We have not been able to reach the ideal production rate for operation yet, but we have been very close to. This has reduced the bottleneck occurring in the queue. The results obtained are huge revenue exceeding the estimates reaching 135%. Hospital get additional revenues and also increased capacity which is the main target of improvement efforts.
