Abstract
Health care system always achieved a challenge to provide high quality of health care and unlimited resources. Important aspect that needed to be developed in health care system in National Health Insurance era in order to be able to provide the best care for the patient with efficient resource was the development of procedure for improving patients flow and service timeliness. Most of previous studies had been correlated with the implementation of management lean and waste identification, but none of instrument of waste identification was tested its validity and reliability as one of the efficiency steps in lean hospital. Based on it, it required to develop the instrument of waste identification and conducted validity and reliability test of its instrument. This research aimed to develop the waste identification instrument adopted from Lean Management System Handbook in the outpatient unit of Dr. Sayidiman Hospital, Magetan, Indonesia. The conducted tests were content validity test and construct validity test for conducting the instrument of validity test, which used correlation test of Pearson Product Moment, and the reliability test used Cronbach’s Alpha method. The total of participants was 33 who consisted of 28 nurses from 17 polyclinic and 5 doctors. The content validity test, among the 100 items of adopted questions, there were 25 items of irrelevant questions which were used in hospital service, thus, they were removed by the researchers. The result of expert’s review among 75 items that the researchers proposed, 5 items of the questions were removed due to irrelevant questions and 4 items of questions were revised for grammatical rules and each items were combined, from two items became one item of question because those questions had similar meaning. Thus, from the results of expert’s reviews, it was obtained 68 items and they were used for first stage test by involving 26 participants. After constructing the validity, the result of the first stage test showed that 12 items of questions showed invalid result and 56 items showed valid result because the score was > 0.4044 (r table value). Based on 56 items of questions in test result of first stage, it was conducted the test result of second stage by involving 33 participants. The result of validity test showed that 17 items of 56 items in the instrument of waste identification were invalid because they had Pearson Correlation value in < 0.3440. The result of reliability test by using Cronbach’s Alpha, based on 39 items questions, which were valid, showed that the instrument was valid and had score of 0.878 ( >0.6). The instrument of waste identification could be used to identify waste in outpatient installation due to its validity and reliability. Further research was required in order to know the effectiveness of the waste identification checklist.
