Performance Analysis of a Medical Record Exchanges Model

Abstract

Electronic medical record exchange among hospitals can provide more information for physician diagnosis and reduce costs from duplicate examinations. In this paper, we proposed and implemented a medical record exchange model. According to our study, exchange interface servers (EISs) are designed for hospitals to manage the information communication through the intra and interhospital networks linked with a medical records database. An index service center can be given responsibility for managing the EIS and publishing the addresses and public keys. The prototype system has been implemented to generate, parse, and transfer the health level seven query messages. Moreover, the system can encrypt and decrypt a message using the public-key encryption algorithm. The queuing theory is applied to evaluate the performance of our proposed model. We estimated the service time for each queue of the CPU, database, and network, and measured the response time and possible bottlenecks of the model. The capacity of the model is estimated to process the medical records of about 4000 patients/h in the 1-MB network backbone environments, which comprises about the 4% of the total outpatients in Taiwan.

Performance Evaluation of a Web-Based System to Exchange Electronic Health Records Using Queueing Model (M/M/1)

“…In Huang and Liou (2007), the proposed database was Oracle. In our work, we use different databases in order to choose to most efficient.…”

“…For the database queue we have to discriminate between [11]. Hence, the minimum theoretical time to send a 5 kB Web page through a 1 Mb Internet connection is approximately 129 ms.…”

“…We consider that the arrival rate of a request in our system follows a Poisson distribution [11], so response time is calculated with Eq. 1 [13].…”

“…Accordingly, the choice of the database is very important when implementing any telematics system. Queueing theory models are typically used to measure response times of a web-based system [11].…”

A Non-Repudiated and Traceable Authorization System Based on Electronic Health Insurance Cards

“…In addition, researchers [15] have pointed out that, electronic medical record exchange among hospitals can provide more information for physician diagnosis and reduce costs from duplicate examinations. In 2007, an Eanamnesis management measure has been proposed by Matsunami [27] to solve the expensive-cost problem of digitization in the post schemes.…”
