Long waiting time is one component that has the potential to cause patient dissatisfaction. If the waiting time is long, it will reduce patient comfort and affect patient utility in the future. The method used in this research is Literature Review, namely by collecting and processing research data that has existed before with the 2018-2022 range. The results of this study found that there was a waiting time for drugs, both concoctions and standard drugs, that were not in accordance with the minimum service standards, so that waste was found. There are various types of waste that are found resulting in long drug waiting times such as too many processes to the long process of submitting drug prescriptions to pharmaceutical installations, which causes many inefficient and ineffective activities to arise. Based on this, there is a waiting time for drugs, both concoctions and standard drugs, that are not in accordance with the minimum service standards, so that waste is found. Thus the length of waiting time in preparing the drug is influenced by several factors such as speed and completeness of patient data up to re-submission which takes a lot of time.

Outpatient services are an important part of health services provided by hospitals. However, some BPJS hospitals experience obstacles in providing efficient and quality outpatient services, such as long queues, long waiting times, and lack of a good management system. the application of Lean Management to the outpatient services of BPJS patients in hospitals can help hospitals improve operational performance, so as to increase public trust in BPJS Health. This study aims to analyze the application of Lean Management to the outpatient services of BPJS patients in hospitals. This research uses a literature study method or Systematic Literature Review using the Google Scholar search engine and journal databases, such as Researchgate. The results showed that most outpatient service activities for BPJS patients still have patient waiting times below the established service standards. In analyzing the flow that patients go through, each activity is identified into two groups, namely Value Added (VA) as an activity that is considered necessary and profitable and Non Value Added (NVA) as an activity that is considered unnecessary. Based on the percentage of waste in the form of the largest waiting time can be described, namely, 35.1% in the registration process, 30.2% in the poly examination process, and 20.7% in the process of receiving drugs in the pharmaceutical installation
