cardiac patients who completed a longitudinal psychosocial study had a different clinical and psychosocial baseline profile than patients who dropped out prematurely
European Journal of Preventive Cardiology, 2015Co-Authors: Nikki L Damen, Henneke Versteeg, Susanne S Pedersen, Patrick W Serruys, Ron T Van Domburg, Robert Jan Van Geuns, Eric BoersmaAbstract:Non-response is a serious threat to the external validity of longitudinal psychosocial studies. Little is known about potential systematic differences between patients with coronary artery disease who complete a psychosocial study and those who drop out prematurely due to non-response, or whether Drop-Outs may have a different cardiovascular risk. We studied a cohort of 1132 consecutive patients undergoing percutaneous coronary intervention (PCI). At baseline, all patients completed the Hospital Anxiety and Depression Scale (HADS) and the Type D Scale (DS14). At 12 months follow-up, 70.8% (n = 802) of patients completed both questionnaires, while 29.2% (n = 330) dropped out. We observed significant differences in socio-demographic, clinical, and psychological baseline characteristics between completers and Drop-Outs. Drop-Outs were younger, more likely to smoke, but less often prescribed cardiovascular medications, including calcium antagonists and angiotensin-converting enzyme inhibitors, as compared with completers. Drop-Outs more often had depression, anxiety, and negative affectivity, as compared with completers (all p-values <0.05). After a median follow-up of 4 years, we found no significant differences in mortality risk between completers and Drop-Outs (6.5 vs. 7.3%; adjusted HR 1.34, 95% CI 0.82–2.19, respectively). In conclusion, a possible attrition bias occurred, as Drop-Outs and completers differed systematically on some socio-demographic, clinical, and psychological baseline characteristics. Despite these differences, this did not translate into a poorer short-term prognosis, as there were no differences in the mortality risk of completers vs. Drop-Outs after a median follow-up of 4 years. In future prospective studies, attention should be paid to attrition bias, and its possible impact on study results and implications should be discussed.
