Implementing cardiovascular disease preventive care guidelines in general practice: an opportunity missed

To the Editor: The research letter by Hespe and colleagues1 on cardiovascular disease prevention is itself a missed opportunity to illuminate the complexities of person‐focused management of patients in general practice. While it provides a snapshot on cardiovascular disease prevention, it does not offer any exploration of the veracity or otherwise of these findings. Aggregate decontextualised and — as acknowledged — limited data ultimately fail to identify the true nature of the problem. Simply focusing on easily extractable data from computerised medical record systems, without linkage to the unique features and context of the person to whom these data belong, necessarily results in a distorted picture. Big data has the potential to inform only if it is appropriately interpreted and may be useful in process monitoring. Such data have a limited role in assessing general practitioner performance and outcomes of care.2
