Impact of a PROgram of Cardiovascular nursE interventionS in a VALVular haEmodynamic Unit (PROCESS-VALVE) on Quality Indicators: A Quasi-Experimental Ambispective Study

Background: The percutaneous treatment of heart valve diseases carried out in the hemodynamic service is constantly growing. After analyzing the mortality, readmissions, success of the procedure, and complications, several studies support this type of percutaneous procedure. The increase in these procedures has required the creation of multidisciplinary teams and new diagnostic and care circuits, such as presurgical consultations and postsurgical follow-ups. Even so, there is little evidence regarding the effect of these consultations on quality indicators.Purpose: The objective of this study is to evaluate the impact of a program of presurgical and postsurgical nurse interventions (PROCESS-VALVE) on quality indicators of the health of patients undergoing percutaneous valve procedures.Patients and Methods: The influence of presurgical and postsurgical consultations on quality indicators will be evaluated through an ambispective quasi-experimental study. Patients will be recruited at a tertiary-level hospital in Barcelona, Spain. For the control group, data will be collected retrospectively from patients who underwent percutaneous valve procedures but did not receive pre-or postsurgical consultations. The intervention group comprises those patients agreeing to participate in the study and the hemodynamic nurse valve consultation program (PROCESS-VALVE). In addition, we will assess whether a face-to-face postsurgical consultation equally improves quality indicators compared to postsurgical telephone consultation; for this, a sub-study will be carried out comparing face-to-face or telephone postsurgical follow-up by means of a randomized controlled clinical trial with simple blinding in the intervention group.Discussion: This study will generate scientific evidence regarding the impact on quality indicators of a nursing intervention via presurgical and postsurgical consultations. In addition, it will allow us to decide the most appropriate follow-up strategy for this type of patient.
