NorthWise Services Patient Diary Cards - Background • Some studies require use of patient diary cards for collection of data • Sometimes the patient self report is on the primary endpoint, or an important secondary endpoint • Traditional approach is to use paper patient diary cards • One objective: reduce the amount of paper used • Related objective: make best use of modern technology NorthWise Services
NorthWise Services Problems with Paper Diary Cards • Patients complete them retrospectively, just before appointment with investigator • Patients also complete them prospectively • They are not filled in accurately • They are often incomplete, inconsistent, inaccurate, biased NorthWise Services
NorthWise Services Objectives of Electronic Patient Diary Use Key objectives are: • Improve patient compliance to protocol • Improve quality of data collected NorthWise Services
NorthWise Services Compliance, Checks and Patient Experience • Patient compliance can be tracked – particularly important in early stages of study • Audit trail is produced • Automatic data entry checks can be built in • Diary devices can be used to accurately record patient experience • Quality of life data can be collected • Collect data in real time NorthWise Services
NorthWise Services Time and Costs • Use of new technology reduces development time, hence time to market for a product – leads to increased revenue for the pharmaceutical company • When all related costs are taken into account devices can be cheaper than paper diaries NorthWise Services
NorthWise Services Published Comparison - Electronic vs. Paper • Key publication : Patient non-compliance with paper diaries (BMJ, Vol 324, 18 May 2002) • Data quality and compliance from paper diaries might be poor, but how can we tell which are the poor data ? • Money is wasted if spent on collecting poor quality data NorthWise Services
