6 Bipolar Disorder: Difficult to Study Bipolar disorder is > Episodic (manic, hypomanic, depressed, mixed, rapid cycling) > Recurrent and life-long illness > High variability within and between patients Major treatment goals: relapse and suicide prevention, interepisodic mood stability Longitudinal mood charting is essential methodology for diagnostic, treatment and research 30-Aug-06 Bauer et al, Using Technology To Improve Longitudinal Studies.. in Bipolar Disorder 6

7 Why Self-Charting? Only possibility to record daily Daily recording may capture observations that would be missed if data were only collected at clinical (doctors) visit Daily self-reported data provides doctor important information about a patients mood variation 30-Aug-06 Bauer et al, Using Technology To Improve Longitudinal Studies.. in Bipolar Disorder 7

8 Why Self-Charting? Study in bipolar disorder with weekly clinician ratings captured only 34.1% of days of depression and 14.1% of days of mania compared to daily patient selfreporting (Denicoff et al. 1997) 30-Aug-06 Bauer et al, Using Technology To Improve Longitudinal Studies.. in Bipolar Disorder 8

9 Why Self-Charting? Several studies in bipolar disorder: process of self-charting of illness parameters may enhance and compliance with prescribed medications (Denicoff et al. 2000, Post et al. 2003) Enhanced adherence to medication improves outcome 30-Aug-06 Bauer et al, Using Technology To Improve Longitudinal Studies.. in Bipolar Disorder 9

10 Benefits of Mood Charting Track pattern of disorder > Cycle (episode) length > Frequency > Episode type > Switching speed Track episode triggers (early warning signs of relapse) Track treatment response > New medications > Polypharmacy > Other treatments 30-Aug-06 Bauer et al, Using Technology To Improve Longitudinal Studies.. in Bipolar Disorder 10

11 Paper-Based Mood Charting NIMH Life Chart (R. Post) STEP-BD Mood Chart (G. Sachs) Chronosheet (P. Whybrow) Used for individual treatment, patient education and longitudinal studies 30-Aug-06 Bauer et al, Using Technology To Improve Longitudinal Studies.. in Bipolar Disorder 11

12 Traditional Longitudinal Studies Paper-based mood charting instruments Expensive High patient drop-out rate High missing value rate Large imbalances in number of observations 30-Aug-06 Bauer et al, Using Technology To Improve Longitudinal Studies.. in Bipolar Disorder 12

13 Traditional Data Quality Handwritten documents Data entry introduces errors Slow analysis Poor patient compliance Recall errors 30-Aug-06 Bauer et al, Using Technology To Improve Longitudinal Studies.. in Bipolar Disorder 13

14 Computers Commonplace Worldwide 47% increase in household personal computers since % of US households have 1 personal computers Microsoft Windows used on 90% of personal computers in US Microsoft Windows used on 85% of personal computers worldwide 60% of households in Australia, Denmark, Netherlands, Norway, Singapore, South Korea and Sweden have 1 personal computers as of Aug-06 Bauer et al, Using Technology To Improve Longitudinal Studies.. in Bipolar Disorder 14

15 Automating Data Collection Error checks at time of data entry Data definition is standardized Preferred by many patients Used to monitor a variety of chronic illnesses 30-Aug-06 Bauer et al, Using Technology To Improve Longitudinal Studies.. in Bipolar Disorder 15

16 Technology Options: Overview Common technologies that have been used to automate patient data collection for a variety of medical conditions are: >PDA (Personal digital assistant) >IVR (Telephone/Interactice Voice Response) >Web-based software >Software on a home computer Each technology has strengths and weaknesses 30-Aug-06 Bauer et al, Using Technology To Improve Longitudinal Studies.. in Bipolar Disorder 16

17 Personal Digital Assistant (PDA) Strengths >Eliminates data entry errors >Devices are portable and re-usable by study sponsor Weaknesses >Most software is not validated >Not suitable for text entry >Devices can be hard to read >Devices can be lost or stolen >Data is not secure >High maintenance cost 30-Aug-06 Bauer et al, Using Technology To Improve Longitudinal Studies.. in Bipolar Disorder 17

18 Integrated Voice Response (IVR) Strengths >Very easy to use >Patients only need a touch-tone phone >No costs to patient Weaknesses >Simple yes/no or multiple choice questions only >High initial cost to sponsor 30-Aug-06 Bauer et al, Using Technology To Improve Longitudinal Studies.. in Bipolar Disorder 18

19 Web Based Software Strengths >Eliminates data entry costs >No patient hardware costs for sponsor Weaknesses >Patients must have access to a computer >On-line system security requires trained IT staff to monitor 24 by 7 >Custom software development is expensive 30-Aug-06 Bauer et al, Using Technology To Improve Longitudinal Studies.. in Bipolar Disorder 19

20 Software On Home Computer Strengths >Eliminates data entry costs >No patient hardware costs for sponsor >Low administrative support costs Weaknesses >Patients must have access to a computer >Security must be designed into the system >Custom software development is expensive 30-Aug-06 Bauer et al, Using Technology To Improve Longitudinal Studies.. in Bipolar Disorder 20

21 Technology Selection Evaluate technology alternatives for each unique project, patient population and clinical setting Use validated software or devices (FDA) Consider on-going administrative and support costs, and initial development costs 30-Aug-06 Bauer et al, Using Technology To Improve Longitudinal Studies.. in Bipolar Disorder 21

22 Successful Projects Focus on Process A well-defined process is required for a successful project regardless of which technology is used On-going commitment of project sponsors and management Process documentation for staff and patients Staff and patient training Clear assignment of responsibilities On-going security and privacy management 30-Aug-06 Bauer et al, Using Technology To Improve Longitudinal Studies.. in Bipolar Disorder 22
