In June 2019, the Norwegian Institute of Public Health (NIPH) has released an HTA report for prehospital CT for early diagnosis and treatment of suspected acute stroke or severe head injury to evaluate the documentation for clinical efficacy, safety and possible initiation of treatment prior to arrival in hospitals, compared with current hospital practice. Although the mobile stroke unit care increases the number of patients who receive thrombolysis, its efficacy is unknown due to the lack of evidence.
