To test the effectiveness of discharge guidance based on the theoretical framework of the Omaha System on Mainland Chinese patients with angina without interventional treatment.

A randomized controlled trial was conducted on 150 Mainland Chinese patients with angina without interventional treatment between December, 2015 and September, 2016. The participants were randomly allocated to discharge guidance based on the Omaha System or usual care. The participants were assessed with the self-designed Problem Rating Survey Scale, including three dimensions and seven items. The Cronbach's alpha coefficient was 0.81. The 7-item-level content validity index was 0.80-1.00 and the scale-level content validity index was 0.94.

The scores of the outcome measures differed significantly between the two groups at all three time points (admission day; 3 days before discharge; discharge day) and increased gradually. Improvements in knowledge, behavior , and the total score of the intervention group were significantly higher than those of the control group. An improvement in status did not differ significantly.

The Omaha System-based discharge guidance is effective at enhancing knowledge and behavior in patients from Mainland China with angina without interventional treatment.
