Laboratory Reports

Iwate Medical University Hospital Dec.2005

I. Preface

In 1897, Iwate Medical University Hospital was established as Iwate Hospital by Shunjiro Mita. Since then, it has gone through post war revolution in medical education and formulation of Medical Practitioners Law and became Iwate Medical University in 1951. As the only medical education organization in Iwate prefecture, since 1956 they have contributed in community medicine by establishing a dental college hospital and an affiliated Hanamaki onsen hospital, expanding their facilities and operations and are continuing to grow as an integrated medical and dental university.

II. Striving to become a desired laboratory

Department director Suwabe:
Including the dental department, our hospital has 1,087 beds and we receive 1,600 outpatients a day. Because we receive so many samples, it used to take us over an hour to complete analyses; from the time the sample was set to the time measurement completed. But because there were demands from patients and clinical side for quicker test result reports as rapid testing results meant shorter hospitalization for patients, we leveled off sample collection and got rid of peak times and have been working on providing accurate reports quickly.
Another problem was that because our laboratory was reconstructed from patients’ rooms, there was no large area available which caused various sections of the laboratory to be divided up.
That is why last year for our LAS renewal, we wanted to focus on a system that would enable 24 hour continuous operation, rapid test reporting and minimized space occupied by the system, which led to our decision on implementing the compact one-line transportation system, Open LA21 module system.

III. LAS (Open LA21 Module System)



OpenLA21 Module System

Sample loading / Unloading and sorting

The sample loading module set in front of sample reception made the flow of sample loading very smooth. Also, the unloaded mother samples are sorted and kept in 50 position racks which simplified operations.

Sample Loading Module / Unloading and Sorting Module


First test tube caps (seal stopper) are removed by the de-cap module. As this used to be manually handled by technologists, we improved the efficiency of this operation by installing the de-cap module. Next, the aliquot module prepares daughter samples for online/ offline analyzers. Barcode labels are applied automatically when daughter samples are prepared for offline analyzers.

De-cap Module / Aliquot Module

EA07U/ 504X

EA07U / 504X

EA07U measures Na, K, and Cl of serum and urine, and 504X measures urine items.
With 504X, only an optimal proportional amount of sample and reagent are used for measurement because even when dilution ratio is set by test item, it does not lower the throughput. Before renewing LAS, sample amount was decreased for measurement in order to ensure its range and reruns for samples with high values were manually done.



3 units of biochemistry modules, JCA-BM2250LA (JEOL), are installed. With a total maximum of 7,400 tests/h throughput and half the consumption of reagents than the conventional amount used, we selected this unit to cutback on cost. The height of this analyzer enabled all technologists to have a visually open view of the laboratory which improved our working environment.

IV. Actual improvements made by LAS implementation

Department director Suwabe:
Renewing LAS has brought us various advantageous effects. First of all, test results are reported within an hour where before the system was renewed TAT* took over an hour. It has also saved us space by occupying only half of the space the old system took up and allowed us to bring laboratory operations from other locations together. By placing the analyzers and workers all together in one area, technologists are able to go out to the hospital wards and answer patients’ questions as received as well as improving communication with doctors and nurses.
*TAT (Turnaround Time): the time from sample arrives to the laboratory to when test results are reported

V. LIS – Laboratory Information System

Department director Suwabe:
At our laboratory, with CLINILAN GL as our backbone system we handle 900 samples on peak days of the week. Data from an analyzer group with the construction that could minimize TAT are verified from various angles and efficiently utilized. In the hematological testing division, microscopic images taken from the CCD camera are imported into the testing system and the graphics are used in reports.



VI. Management of an open-door laboratory

Department director Suwabe:
At our laboratory, we promote open-door laboratory as being part of the medical team instead of just conducting daily operations. For example, we began offering laboratory tours for patients who get comprehensive medical examination. By actually seeing the analyzers, their interest towards testing and understanding towards our profession has increased. Also, by improving the efficiency in conducting daily work, we have freed time where we hold study sessions with doctors and nurses on a regular basis. As a result, problems that occur on site which relate to testing have become clear and have helped improve daily operations. We will continue to strive to become an ideal laboratory for those inside and outside of the hospital keeping it the open-door laboratory by discussing and handling requests and questions raised.
