Participants	DESCRIPTION : cardiac patients / surgery patients. GEOGRAPHIC LOCATION: USA. SETTING: discharged home from an acute care setting. NUMBER OF PARTICIPANTS: ELIGIBLE: unclear. RANDOMISED TO INTERVENTION: 30. RANDOMISED TO CONTROL: 30 ‐ 30. INCLUDED IN ANALYSIS INTERVENTION GROUP: 30. INCLUDED IN ANALYSIS CONTROL GROUP: 30 ‐ 30. AGE: RANGE OR MEAN (SD): 63.1 (9.8). GENDER (% MALE): 81. ETHNICITY: unclear. PRINCIPAL HEALTH PROBLEM OR DIAGNOSIS: coronary artery disease. OTHER HEALTH PROBLEM/S: unclear. TREATMENT RECEIVED/RECEIVING: coronary bypass surgery. OTHER SOCIAL/DEMOGRAPHIC DETAILS: 90% married. Average hospital stay of 6.2 days.
Interventions	DETAILS OF INTERVENTION: A teaching protocol was implemented during postdischarge week two by the cardiac rehabilitation nurse via telephone. The telephone contact was a method to reinforce the teaching content which had been previously given in the hospital. There were also opportunities for the patient to clarify any additional topics with the cardiac rehabilitation nurse. DETAILS OF CONTROL Two control groups: one received inhospital teaching only, the other inhospital teaching plus post discharge group teaching. CO‐INTERVENTION? yes. DETAILS OF CO‐INTERVENTIONS: All groups received inhospital teaching by the cardiac rehabilitation nurse on postoperative day 5 or 6; the content of this inpatient teaching protocol consisted on wound healing, signs and symptoms of angina/MI, guidelines for activity progression, incisional care, risk factor modification, dietary modifications and method for enrolling in cardiac rehabilitation. Patients also received two teaching booklets. DELIVERY OF INTERVENTION Frequency: 1. First time at day 7 to 14 after discharge. Period: PROVIDERS: nurse. INTERVENTION QUALITY: unclear. FIDELITY/INTEGRITY: unclear.
Outcomes	NUMBER OF OUTCOMES: 2. OUTCOME / TOOL / TOOL VALIDATED / METHOD OF ASSESSMENT / TIME OF ASSESSMENT A. Psycho‐social health of patients (uncertainty, anxiety, informational needs, mood, coping, quality of life, social activity, ..): satisfaction / self‐developed / partly, adopted from Gerard and Peterson's cardiac patient learning needs inventory / unclear / unclear, but in first month after discharge. B.Physical health of patients (eg. functional status, self‐care, self‐efficacy, independence, ..): C.Other consumer oriented outcomes (eg. treatment adherence, knowledge, adverse events, ..): knowledge / self‐developed: heart disease management questionnaire / partly; Kuder‐Richardson coefficient 0.36 / unclear / unclear, but in first month after discharge. D. Health service delivery oriented outcomes (eg. hospital readmission, health services utilization, ..):
