Key result
Experiencing ≥5 shocks was strongly associated with low treatment satisfaction in patients with an implanted cardioverter defibrillator (OR 10.17; 95% CI 3.57-29.00; P≤0.001).

Experiencing multiple ICD shocks, being employed, and feelings of helplessness are strong predictors of low treatment satisfaction, highlighting the need for psychological support in these patients.
Multiple ICD shocks may flag need for psychological support; cross-sectional data leaves open causal effects and intervention benefits.
The evaluation of low treatment satisfaction (LTS) with an implanted cardioverter defibrillator (ICD) remains a neglected area of clinical research. However, a trustful attitude toward an ICD is crucial. Within the scope of ICD health technology assessment, we searched for predictors of LTS. Of 195 ICD patients enrolled (mean 59.8 years, standard deviation 12.6), 163 (83.6%) were men and 26 (16.4%) were women. We measured anxiety, helplessness, and depression with standardized instruments and LTS with 11 dichotomous items concerning a mistrustful attitude, a negative body image, and low appraisal. A total of 47 (24.1%) patients were considered as LTS patients. Multivariate logistic regression was used for assessment of LTS. Adjusted for age and survey, LTS was significantly more prevalent in depressed, anxious, and phobic patients. Multivariate logistic regression including medical and psychological covariates revealed the experience of > or =5 shocks with an odds ratio (OR) of 10.17 (95% CI 3.57-29.00, P < or = 0.001), being employed with an OR of 8.07 (95% CI 2.39-27.19, P < or = 0.001), and feelings of helplessness (OR 4.61, 95% CI 1.79-11.90, P < or = 0.002) as the most important predictors for LTS. Women had a slightly not significant effect on LTS. Age, educational status, and depression were not significant. LTS patients required more support for living with the ICD (P < or = 0.001). Thus, LTS serves as surrogate measure for deteriorated psychic health. Clinicians should be advised to identify LTS patients and to consider psychotherapeutic counseling for them.

Ladwig et al. (2005) conducted an observational in Implanted cardioverter defibrillators (ICD) (n=195). Experience of ≥5 shocks vs. Experience of <5 shocks was evaluated on Low treatment satisfaction (LTS) (OR 10.17, 95% CI 3.57-29.00, p=≤0.001). Experiencing ≥5 shocks was strongly associated with low treatment satisfaction in patients with an implanted cardioverter defibrillator (OR 10.17; 95% CI 3.57-29.00; P≤0.001).
