In the article, Assessment of efficacy and safety of combining “paclitaxel” eluting balloon and “limus” eluting stent in the same lesion, Basavarajaiah et al. (2013) performed a study in which they looked at using a drug-eluting balloon and drug-eluting stent together for treatment of coronary artery blockages. The design of the study was as follows:
-A group of patients (155) between 2009 and 2011 had percutaneous interventions (PCI) performed. The initial strategy was to use only a drug-eluting balloon (DEB), which is a relatively new treatment for coronary lesions.
-If the drug-eluting balloon alone was not sufficient to adequately reduce the stenosis, then “bail-out” stenting was performed to keep the artery open. The researchers determined whether of not to use a bare-metal stent (BMS) or drug-eluting stent (DES) for bail-out.
-The determination for bare-metal vs. drug-eluting stent was made based on factors that categorized the patient as high-risk or not. High-risk patients received the DES the patients with less risk received BMS.
The goal for the researchers was to determine if the DEB/DES treatment was safe and efficacious. The randomization of treatment (DEB alone, DEB/BMS, DEB/DES) was effectively dictated by the patient’s comorbidities and coronary pathophysiology, as well as intra-procedural findings. The patients were then followed up later and data was collected with regard to clinical outcomes based on pre-determined categories. This data was analyzed and it was determined that the use of the DEB/DES combination was safe and efficacious.
I believe that this experiment was a randomized controlled trial. There were three groups treated in different ways (DEB alone, DEB/BMS, DEB/DES) with the emphasis being on determining if the DEB/DES combination was safe and effective. Per Polit & Beck (2012), the 3 factors that make up a true RCT are manipulation, control, and randomization. In this study, all patient groups had interventions performed (manipulation). Controls and randomization were dictated by comorbidities, coronary pathophysiology, and intra-procedural findings. According to Polit & Beck (2012), this is considered the “gold standard for yielding reliable evidence about cause and effect”.
