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. (waiting times, patient satisfaction, admission times, hospital readmission, mortality, intrahospital complications and nosocomial infections). Design of the study is an ambispective quasi-experimental study. For the control group, data will be collected retrospectively from patients undergoing percutaneous valve procedures who did not receive pre- or postsurgical consultations. The intervention group will comprise those patients who agree to participate in the study and the haemodynamic nurse valve consultation program (PROCESS-VALVE). In addition, the investigators will assess whether a face-to-face postsurgical consultation improved 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 randomised controlled clinical trial with simple blinding in the intervention group. Study area will be at the Hemodynamic Unit of the Hospital de la Santa Creu i Sant Pau and the study population are chosen patients for percutaneous valvular intervention who attend the pre-surgical consultation at our center. Dependent variable will be the indicators cited in the study aim and the independent variable will be the pre-surgical and post-surgical consultation. In pre-surgical consultation will be done a patient recruitment and will collect sociodemographic and clinical data. At patient will be done an individualized interview with an Ad-Hoc questionnaire and to collect fragility level of study and level of planned connections. In the subsequent follow-up, all pacients will receive a follow-up visit and collect satisfaction and quality indicators. But this pacients will be randomized to telephone follow-up or face-to-face follow up. Sample size has been calculated in 194 to be distributed equally in both groups and the clinical trials groups will be formed by 94 patients in each group The protocol has been modified to an ambispective quasi-experimental study with a subsequent randomization for the type of follow-up (telephone vs face-to-face) due to organizational changes in the participant center.
