Purpose Introducing workflow management technology in healthcare seems to be prospective in dealing with the problem that the current
healthcare Information Systems cannot provide sufficient support for the process management, although several challenges still
exist. The purpose of this paper is to study the method of developing workflow-based information system in radiology department
as a use case.
Method First, a workflow model of typical radiology process was established. Second, based on the model, the system could be designed
and implemented as a group of loosely coupled components. Each component corresponded to one task in the process and could
be assembled by the workflow management system. The legacy systems could be taken as special components, which also corresponded
to the tasks and were integrated through transferring non-work- flow-aware interfaces to the standard ones. Finally, a workflow
dashboard was designed and implemented to provide an integral view of radiology processes.
Result The workflow-based Radiology Information System was deployed in the radiology department of Zhejiang Chinese Medicine Hospital
in China. The results showed that it could be adjusted flexibly in response to the needs of changing process, and enhance
the process management in the department. It can also provide a more workflow-aware integration method, comparing with other
methods such as IHE-based ones.
Conclusion The workflow-based approach is a new method of developing radiology information system with more flexibility, more functionalities
of process management and more workflow-aware integration. The work of this paper is an initial endeavor for introducing workflow
management technology in healthcare. 相似文献

The purpose of this study is to ascertain the error rates of using a voice recognition (VR) dictation system. We compared
our results with several other articles and discussed the pros and cons of using such a system. The study was performed at
the Southern Health Department of Diagnostic Imaging, Melbourne, Victoria using the GE RIS with Powerscribe 3.5 VR system.
Fifty random finalized reports from 19 radiologists obtained between June 2008 and November 2008 were scrutinized for errors
in six categories namely, wrong word substitution, deletion, punctuation, other, and nonsense phrase. Reports were also divided
into two categories: computer radiography (CR = plain film) and non-CR (ultrasound, computed tomography, magnetic resonance
imaging, nuclear medicine, and angiographic examinations). Errors were divided into two categories, significant but not likely
to alter patient management and very significant with the meaning of the report affected, thus potentially affecting patient
management (nonsense phrase). Three hundred seventy-nine finalized CR reports and 631 non-CR finalized reports were examined.
Eleven percent of the reports in the CR group had errors. Two percent of these reports contained nonsense phrases. Thirty-six
percent of the reports in the non-CR group had errors and out of these, 5% contained nonsense phrases. VR dictation system
is like a double-edged sword. Whilst there are many benefits, there are also many pitfalls. We hope that raising the awareness
of the error rates will help in our efforts to reduce error rates and strike a balance between quality and speed of reports
generated. 相似文献

Cancer Diagnosis Epigenomics Scientific Workflow Scheduling in the Cloud Computing Environment Using an Improved PSO Algorithm 下载免费PDF全文

Objective: Epigenetic modifications involving DNA methylation and histone statud are responsible for the stable maintenance of cellular phenotypes. Abnormalities may be causally involved in cancer development and therefore could have diagnostic potential. The field of epigenomics refers to all epigenetic modifications implicated in control of gene expression, with a focus on better understanding of human biology in both normal and pathological states. Epigenomics scientific workflow is essentially a data processing pipeline to automate the execution of various genome sequencing operations or tasks. Cloud platform is a popular computing platform for deploying large scale epigenomics scientific workflow. Its dynamic environment provides various resources to scientific users on a pay-per-use billing model. Scheduling epigenomics scientific workflow tasks is a complicated problem in cloud platform. We here focused on application of an improved particle swam optimization (IPSO) algorithm for this purpose. Methods: The IPSO algorithm was applied to find suitable resources and allocate epigenomics tasks so that the total cost was minimized for detection of epigenetic abnormalities of potential application for cancer diagnosis. Result: The results showed that IPSO based task to resource mapping reduced total cost by 6.83 percent as compared to the traditional PSO algorithm. Conclusion: The results for various cancer diagnosis tasks showed that IPSO based task to resource mapping can achieve better costs when compared to PSO based mapping for epigenomics scientific application workflow. 相似文献

PurposeThis investigation details the time and teamwork required for CT-guided tandem and ring high-dose-rate brachytherapy.Methods and MaterialsFrom 2010 to 2012, 217 consecutive implantations were identified on 52 patients. We gathered key workflow times: preoperative, applicator insertion, CT image, treatment planning, treatment, patient recovery, and total time in clinic. Linear fixed-effects models were used, and key workflow times were the outcome variables and factors including age, body mass index, stage, outside referral, number of implant per patient, number of implants per day, and year of implantation were examined as fixed effects.ResultsOf the 52 patients, 62% of the patients were Fédération Internationale de Gynécologie et d'Obstétrique Stage 2B, 88% were treated with concurrent chemotherapy, and 23% were treated at an outside facility and referred for the procedure. The mean times (minutes) for each step were as follows: preoperative evaluation, 93; insertion, 23; imaging, 45; treatment planning, 137; treatment, removal, and recovery, 115; total clinic time, 401. For the insertion time, the greater implant number per patient was significantly associated with a decreased total insertion time, with and without adjusting for other covariates, p = 0.002 and p = 0.0005, respectively. Treatment planning time was expedited with increasing number of implant per patient and comparing treatment times in 2012 with those in 2010, p = 0.01 and p < 0.0001, respectively.ConclusionsGynecologic brachytherapy requires a skillfully coordinated and efficient team approach. Identifying critical components and the time required for each step in the process is needed to improve the safety and efficiency of brachytherapy. Continuous efforts should be made to enhance the optimal treatment delivery in high-dose-rate gynecologic brachytherapy. 相似文献
