Factors influencing attendance at cardiac rehabilitation among coronary heart disease patients.
OBJECTIVE: The current study examined predictors of, and reasons for, non-attendance at cardiac rehabilitation (CR) among coronary heart disease patients. METHODS: Measures of demographics, surgical procedures, cardiac risk factors, cardiac damage, and psychological variables (depression, trauma, anxiety and alexithymia) were obtained at baseline in 85 coronary heart disease patients, of whom 34 (40%) attended CR. Patients not attending CR reported reasons for their non-attendance. RESULTS: Men who had a sedentary lifestyle or were obese were significantly more likely to attend CR. Women were significantly more likely to attend CR if they had a partner. Patients reported numerous personal reasons for their non-attendance, some of which reflect a dislike of a group format. CONCLUSION: The results suggest the presence of obstacles to attendance and completion of CR that may differ for men and women. Innovative approaches are needed to encourage participation, including the development and evaluation of alternative formats of CR.
Feasibility of a cognitive-behavioural group intervention for men experiencing psychological difficulties after myocardial infarction.
BACKGROUND: People experiencing psychological distress after a cardiac event may require special follow-up and targeted interventions in order to effectively decrease levels of distress. AIMS: Men who were judged to be experiencing poor emotional adjustment post-myocardial infarction (MI) were invited to a cognitive behaviour therapy group. The current study examines the attendance at such a group and the consequent feasibility of such interventions. METHOD: The content of the group aimed to help men deal with the uncomfortable psychosocial issues that had arisen since having a MI. RESULTS: Of the 26 men approached only 30% were interested in attending and only 11% actually completed the group. Two men who were committed to attending the group could not complete all the sessions, as heart bypass operations became available to them. CONCLUSION: Ways of involving men in interventions targeting psychological distress requires ongoing investigation.
A new solution for an old problem? Effects of a nurse-led, multidisciplinary, home-based intervention on readmission and mortality in patients with chronic atrial fibrillation.
BACKGROUND: Atrial fibrillation (AF), the most common chronic cardiac dysrhythmia, is an important cause of cardiovascular morbidity and mortality. However, there is a paucity of studies examining the potential benefits of optimizing the postdischarge management of patients with chronic AF. RESEARCH OBJECTIVE: To examine the effects of a nurse-led, multidisciplinary, home-based intervention (HBI) on the pattern of recurrent hospitalization and mortality in patients with chronic AF in the presence and absence of chronic heart failure (HF). PATIENT COHORT AND METHODS: Health outcomes in a total of 152 hospitalized patients (53% male) with a mean age of 73 +/- 9 years and a diagnosis of chronic AF who were randomly allocated to either HBI (n = 68) or usual postdischarge care (UC: n = 84) were examined. Specifically, the pattern of unplanned hospitalization and all-cause mortality during 5-year follow-up were compared on the basis of the presence (n = 87) and absence (n = 65) of HF at baseline. RESULTS: Patients with concurrent HF exposed to HBI (n = 37) had fewer readmissions (2.9 vs 3.4/patient), days of associated hospital stay (22.7 vs 30.5: P = NS) and fatal events (51 % vs 66%) relative to UC (n = 50): P = NS for all comparisons. In the absence of HF, morbidity and mortality rates were significantly lower but still substantial during 5-year follow-up. In these patients, HBI was associated with a trend towards prolonged event-free survival (adjusted RR = 0.70; P = .12) and fewer fatal events (29% vs 53%, adjusted RR = 0.49; P = .08). HBI patients (n = 31) also had fewer readmissions (2.1 vs 2.6/patient) and days of associated hospital stay (16.3 vs 20.3/patient), although this did not reach statistical significance. On the basis of these data, it was calculated that a randomized study of an AF-specific HBI would require 250 patients followed for a median of 3 years to detect a 25% variation in recurrent hospital stay relative to UC. CONCLUSIONS: These unique data provide sufficient preliminary evidence to support the hypothesis that the benefits of HBI in relation to the management of HF may extend to "high risk" patients with chronic AF in whom morbidity and mortality rates are also unacceptably high. Further, appropriately powered studies are required to confirm these benefits.
