title: The Evaluation of Analytical Performance of Immunoassay Tests by using Six sigma Method
abstract: The Six Sigma Methodology is a quality measurement method in order to evaluate the performance of the laboratory. In the present study, it is aimed to evaluate the analytical performance of our laboratory by using the internal quality control data of immunoassay tests and by calculating process sigma values.  Biological variation database (BVD) are used for Total Allowable Error (TEa) Sigma values were determined from coefficient of variation (CV) and bias resulting from Internal Quality Control (IQC) results for 3 subsequent months. If the sigma values are =6, between 3 and 6, and <3, they are classified as >world class< >good< or >un acceptable< respectively.  A sigma value >6 was found for TPSA and TSH for the both levels of IQC for 3 months. When the sigma values were analyzed by calculating the mean of 3 months, folate, LH, PRL, TPSA, TSH and vitamin B12 were found >6. The mean sigma values of CA125, CA15 3, CA19 9, CEA, cortisol, ferritin, FSH, FT3, PTH and testosteron were >3 for 3 months. However, AFP, CA125 and FT4 produced sigma values <3 for varied months.  When the analytical performance was evaluated according to Six Sigma levels, it was generally found as good. It is possible to determine the test with high error probability by evaluating the fine sigma levels and the tests that must be quarded by a stringent quality control regime. In clinical chemistry laboratories, an appropriate quality control scheduling should be done for each test by using Six Sigma Methodology.

title: Application of the Six Sigma Method for Improving Maintenance Processes Case Study
abstract: The article presents an implementation attempt of the DMAIC method used in the Six Sigma concept for the improvement of production processes connected with maintenance. Thanks to the tools included therein (process map, FMEA, SIPOC chart) we were able to define the: problem, i.e. which types of breakdowns cause the most machine stoppage; precise structure of the failure removal process and its needs, owners, resources, client supplier relationships in particular sub processes; source causes for overly long stoppages. Learning the process and the causes of malfunctions allowed us to develop improvement procedures aimed at minimising the fault removal times. The procedures developed have been implemented in the company alongside a control plan, which will ensure supervision and their efficient functioning in the future.

title: Facilitating Process Changes in Meal Delivery and Radiological Testing to Improve Inpatient Insulin Timing Using Six Sigma Method
abstract: The objective of this project was to improve the timing of inpatient insulin administration related to meal delivery and the scheduling of radiology tests by Lean Six Sigma method.  A multidisciplinary hospital team and a Six Sigma team from a pharmaceutical manufacturer collaborated to evaluate food delivery and radiology scheduling processes related to the timing of insulin administration. Key factors leading to problems within each system were addressed to improve the efficiency of each process while improving the timeliness of glucose testing and insulin administration.  Standardizing the food delivery schedule and utilizing scorecards to track on time meal deliveries to the floor enabled nursing to more accurately administer insulin in coordination with the delivery of meals. Increasing communication and restricting the scheduling of inpatient procedures during mealtimes reduced disruptions to insulin administration. Data at 6 months postimplementation demonstrated that the institution met goals for most primary outcome metrics including increasing on time meal delivery and the proportion of patients taking insulin scheduled for radiology tests during appropriate times.  By implementing the recommendations identified via Lean Six Sigma, this collaborative effort improved the timing of inpatient insulin administration related to meal delivery and radiology testing.
