Assessing the information needs of post-myocardial infarction patients: a systematic review

We systematically reviewed studies examining information needs of post-myocardial infarction patients and their families. Electronic databases and bibliographies of relevant papers were searched and experts in the field contacted to find relevant studies. A standardised data form was used to extract data on study populations, instruments and results. Of 14 published studies, 6 used the same instrument. Information about risk factors ranked as the most important category overall, followed by information on cardiac anatomy and physiology, medications, and physical activity. Information about miscellaneous items, diet, psychological factors, and the CCU, although ranked lower, were still rated important. Some variation between settings was evident. Patients preferred physicians over nurses as information givers. Differences were found between patient and nurse ratings of information categories. Differences were found in the self-perceived information needs of patients responding to different instruments, indicating a priming effect. Changes in ranking of information categories between CCU, PCCU and PD are congruent with decreasing levels of patient dependency. The information needs of women and other post-MI subgroups, including the elderly, minority ethnic groups, patients with severe coronary disease, and deprived patients, have not been assessed. Patients have not been involved in the design of information needs assessment instruments.
