Objectives:
1) Assess the pre and post surgical prevalence of depression and anxiety (D&A) in a representative sample of Coronary Artery Bypass Grafting (CABG) patients using a short screening tool (HADS).
2) Identify sub-groups at an increased risk for developing D&A amongst CABG patients
3) Study the relationship between level of D&A and recovery 1-year post surgery.
Hypothesis:
1) Proportion of D&A will vary so that a higher rate will be found within specific sub-groups: i.e. women, elderly, patients with co-morbid medical conditions;
2) There will be an association between pre-surgical level of D&A and 1-year level of D&A, depending on whether or not individuals had participated in cardiac rehabilitation programs during the post operative year;
3) There will be an association between pre & post surgical level of D&A and patients' health outcomes and quality of life at 1-year follow-up.
Methods:
A prospective study including a representative sample of 1110 CABG patients recruited from 5 cardiothoracic units in Israel, 30% of whom are insured by Maccabi. Participants take part in two interviews:
1) Baseline - before surgery;
2) Follow-up - 12 months thereafter. Data collected include: demographics, co-morbidity, biochemical markers, medication use, medical service utilization, anthropometric measures, lifestyle habits, employment status, functional capacity, depression & anxiety, and quality of life.
Information regarding co-morbidities and biochemical markers is collected from medical charts and documents. During follow-up interview the same information is collected again referring to the year after surgery.
Patients are also asked about cardiac rehabilitation participation. |
