Objectives: To identify patient’s views on the functionality required for personalised access to the secondary care EHR and their priorities for development. Design: Quantitative analysis of a cross-sectional self-complete survey of patient views on required EHR functionality from a secondary care EHR, including a patient ranking of functionality. Setting: Secondary care patients attending a regional cystic fibrosis unit in the north of England Participants: 201 adults [106 (52.7%) male], median age 29 years (range 17-58 years) entered and completed the study. Inclusion criteria; a confirmed diagnosis of CF, aged 16 years and over, at a time of clinical stability Outcome measures: Quantitative responses within 4 themes; 1) value placed on aspects of the EHR; 2) access requirements to functions of the EHR; 3) views on information sent to the EHR 4) patient feedback entered into the EHR. A ranked score for 15 functions of the EHR was obtained Results: Highest ratings (% reporting item as very important/important) were reported for access to clinical measures [lung function (94%), CRP (84%), sputum microbiology (81%) and blood results (80%)], medication changes (82%) and lists (83%) and sending repeat prescription (83%) and treatment requests (80%), whilst sending symptom diaries was less so (62%). Email contact with clinicians was the most valuable communication element of the EHR (84% very important/important). Of 15 features of the EHR [1=most desirable to 15=least desirable) patients identified ‘clinical measures’ [2.62 (CI 2.07-3.06)], and ‘access to medication lists’ [4.91 (CI 4.47-5.44)], as highest priority for development and the ability to comment on errors/ommissions [11.0 (CI 10.6-11.5)] or experience of care [11.8 (CI 11.4-12.2)] as lowest. Conclusions: Patients want extensive personal access to their hospital EHR, placing high importance on the viewing of practical clinical measures and medication management. These influence routine day to day care and are priorities for development
