You've hit the nail on the head.....In reality however, the main reason you can't access or share your own health data in Ireland today is because the former Health Boards were dissolved overnight in 2005 on foot of a decision rooted in political ideology, to form the HSE without any plan as to what might happen with the existing IT processes. This has resulted in an utterly dysfunctional hodge-podge of decades-old systems on life support (pun not intended!).
Imagine, for example, a merger of eleven major companies, with no overarching corporation in charge; what would you think might happen to the their individual IT systems, with the IT staff of each individual company left scratching their heads in a communications vacuum, wondering what just happened?
Who drives the strategy, who establishes and measures the adherence of standards, who implements common processes, who is accountable for consistency across all public health services?
Dysfunctional IT systems are a symptom of dysfunctional organisations.
