This document reports on a survey of patients using an electronic patient health record system called Patients Know Best (PKB). 119 patients with home parenteral nutrition were recruited over 18 months to use PKB. A survey of 58 users found high satisfaction, with most finding PKB useful for contacting nurses, doctors, and dietitians. The survey results suggest patients find PKB a useful tool for managing their long-term condition and improving communication between their healthcare team.
