Mobile Medical Records

1. Mobile Medical Records Paul Brittan Shelley Petzer

2. Overview • Introduction • Problem Statement • Research Questions • Evaluation • Work Allocation • Related Work • Key Success Factors • Risks • Timeline • Conclusion

3. Introduction • Aim is to investigate the secure storage of medical records on cell phones • Original idea was proposed by Simelela • Provide patients with the means to securely manage their medical records • Main Focus for the project • Compressing the data for storage • Secure transfer & encryption of data • Rudimentary interface for testing purposes

4. Problem Statement • Designing applications in developing countries • Access to more advanced technology is limited • A cell phone is ideal because of its diversity • However cell phones create issues • Challenges related to the limited resources • Ensuring the privacy of the medical record

5. Research Questions (Paul) • Comparison of storing medical records on the internal memory of the cell phone as opposed to a microSDcard • The performance comparisons of compression algorithms • Involves the analysis of several lossless compression algorithms • Reducing the storage space of the medical record whilst minimising the resources used

6. Research Questions (Shelley) • The performance comparisons of encryption algorithms • Involves the analysis of several algorithms • Finding an algorithm that maximises security • Minimising the resources required by the cell phone • The transmission medium between the cell phone and a medical database • Investigate the strengths and weaknesses of Bluetooth technology and wireless networks for transmission

7. Evaluation • Test the performance of the encryption & compression algorithms • Test algorithms on anonymised medical records • Analysed according to efficiency and based on resources used • Ideally, we want comparable measurements for • Execution time • CPU usage • Memory usage

8. Evaluation Cont. • Research needs to be done on testing applications for mid-tier phones • Performance monitors • Benchmark tests • Last Resort • Measure the battery power on the cell phone before and after each test

10. Work Allocation (testing)

11. Ethical, professional and legal issues • Ethical issues involved with medical record data • privacy • Plan to use anonymised medical records • No ethics clearance is required • No user testing will take place

12. Related Work • Systems that provide electronic medical records • OpenMRS • Medical records on a cell phone • JavaRosa • Open Data Kit clinic • Early stages of development • Privacy not a priority

13. Anticipated outcomes • Prototype that allows the following: • Storage of medical records on a cell phone • Transmission of medical records between a cell phone and medical database • Encryption and compression of the medical record • Performance analysis

14. Key success factors • Storage and transmission of the medical record • Efficient • Secure • Compressed • Storing the medical record on the internal memory • Transmission using Bluetooth • Analysis of encryption and compression algorithms

15. Risks • Failure to successfully measure performance • Failure to meet milestones • Hardware failure • Gathering medical record data • Group member becomes unavailable

16. Timeline • Research and design: 15 days • Algorithm implementation and testing: 20 days • Merging components with testing: 22 days • Dedicated report writing: 20 days

17. Conclusion • The project will contribute towards a mobile medical record framework • Benefit patients and medical practitioners in medical record management • The project will attempt to cater for developing areas and consider the limitations of a cell phone
