IG was formed from 40 patients who received routine care, treatment and education services of the clinic after open heart surgery, and whose routine controls were determined by the randomization method.

However, the researcher gave the phone number to the patients in the CG in terms of their right to receive ethical and professional care, and it was stated that they could call between 10:00 and 22:00 if needed. The reasons for calling the investigator from the CG were recorded .

From the end of the first week after discharge to the end of the first month, patients were counseled over the phone during the home process. Complications were followed up.

Anxiety levels of all participants who met the inclusion criteria were measured using the state and trait anxiety scale in the pre-test. At the end of the first week after discharge, the intervention was started for the patients in the study group and the intervention was completed at the end of the first month after discharge. One month after discharge, the state anxiety levels were measured again with the state anxiety scale.

The rate of total hospitalization before and after the intervention, the rate of admission to the hospital for examination, leg incision infection, effusion, chest incision infection and other complications that may occur within one month after discharge, according to the groups
