Patient questionnaires regarding patient reported outcomes are valuable information for the treating physician as well as for clinical researchers. To reuse this data, often documented on paper, it needs to be transferred into the respective databases by the medical staff. As this method is time-consuming and error-prone it is rarely done in routine medical care. Therefore, we developed a web-application to capture patient questionnaires on mobile devices. The resulting data is automatically transferred into the electronic health record and available to be used for different clinical purposes. We then evaluated the system with respect to usability and cost effectiveness compared to the paper-based workflow. We used iPads which paid off after 7 months taking into account material and personnel costs of a scientific assistant. The mobile application achieved a system usability score of 80.34 out of 100 points, thus proving a good acceptance by the users. Patients and medical staff reported in semi-structured interviews that they were highly satisfied with the system and they even preferred it compared to the paper-based workflow. Physicians now use quality of life information during treatment. This study shows that the mobile documentation of patient questionnaires is technically feasible and provides valuable data for treatment and research alike.

Mobile Patient Questionnaires – Implementation and Evaluation

  2. 2. Mobile Patient Questionnaires Implementation and Evaluation INTRODUCTIONMobile Patient Questionnaires | Fleur Fritz | 24th November HINZ 2011
  3. 3. Patient Questionnaires Use in Medical Care and Research Patient reported outcomes are important to: • Assess the patient’s perception of their health status, e.g. quality of life • Realize gap between patient-based and physician-based assessment Documented in: • Clinical studies (sometimes) • Routine patient care (rarely)Mobile Patient Questionnaires | Fleur Fritz | 24th November HINZ 2011
  4. 4. Patient Questionnaires Use in Medical Care and Research • “…logistical challenges in collecting, storing, analysing, and reporting PROs in real-time have been a barrier to their use in practice”1 • Patient reported outcomes documented by patients • Manual data transfer into the EHR and/or research database time- consuming and error-prone • Single Source Approach: Capture medical data once and reuse it for different purposes (treatment, research, quality management, etc.) 1 Snyder C, Aaronson N.

  5. 5. Research Question Is there an efficient and user-friendly method to collect patient reported outcomes data by means of patient questionnaires which can then be used for treatment as well as for research purposes?Mobile Patient Questionnaires | Fleur Fritz | 24th November HINZ 2011

  7. 7. The Web-based Application • Hardware-independent • Currently supported questionnaire forms: radio-buttons and visual analogue scale • XML file for data export • Mapping to EHR form data elements • According to usability standardsMobile Patient Questionnaires | Fleur Fritz | 24th November HINZ 2011
  8. 8. The Web-based Application • Competence Center for the Diagnosis and Therapy of Chronic Pruritus • Three different patient questionnaires (DLQI, HADS, PBI) • Evaluation: • More than 100 patients per month (paper-based and electronic workflow) • Time and cost measurements • Patient/Staff questionnaires regarding usability (SUS) and acceptanceMobile Patient Questionnaires | Fleur Fritz | 24th November HINZ 2011

  12. 12. Evaluation - Costs • Personnel costs (manual data transfer) and material costs (paper, staples, printing, energy, ) per paper sheet = 0.18 – 0.40 Euro vs. • Material costs for iPad and accessories iPad paid off after 7 months compared to paper-based workflowMobile Patient Questionnaires | Fleur Fritz | 24th November HINZ 2011
  13. 13. Evaluation - Usability • System Usability Scale Score: 80 from 100 (return rate 94%) • Patients: “[…] I just see advantages, even though I am not a fan of computers. It is much better to read and clearly arranged and it was not difficult at all.” - “ It was really fun!” • Physicians: “[…] it has a significant influence on the treatment. For example when I see that a patient has a high depression score I choose a different medication, this is not possible when I use the paper based version.” - “I would recommend it to other departments.””Mobile Patient Questionnaires | Fleur Fritz | 24th November HINZ 2011
