[ca] El maneig dels catèters venosos perifèrics (CVP) és una competència infermera. L'ús dels CVP està estès al medi hospitalari, però els pacients no estan exempts de complicacions. Els protocols o les guies dels centres hospitalaris sobre el maneig dels CVP en relació amb la flebitis per CVP són heterogenis, el coneixement infermer és limitat i l'aplicació de la pràctica basada en l'evidència (PBE) és escassa. Els objectius generals d'aquesta tesi són dos: 1) Determinar l'evolució de la producció científica i tendències sobre accés vascular i flebitis per cateterisme venós perifèric, i 2) Identificar i consensuar el maneig dels catèters venosos perifèrics a relació amb la flebitis en el context assistencial. S'han fet servir diferents metodologies de recerca per donar resposta als objectius plantejats. Es van fer dues anàlisis bibliomètriques analítiques i descriptives, i dos estudis Delphi, d'àmbit nacional i internacional per consensuar i valorar entre experts el maneig dels CVP. L'estudi internacional també inclou entrevistes semiestructurades als/les experts/es. Aquesta tesi presenta a l'apartat de resultats 4 articles. Els estudis bibliomètrics (N= 995 articles i N=1596 articles) van establir un interès mantingut en el temps sobre l'accés venós relacionat amb el tema de les infeccions i altres complicacions i la necessitat de control i vigilància per part d'infermeria. També es van detectar les àrees a explorar amb relació a la flebitis que van servir de base per als estudis de consens i les àrees d'estudi emergents. L'estudi Delphi d'àmbit nacional va incloure 27 infermeres expertes i l'internacional 18 experts multidisciplinaris i 4 van ser entrevistats per complementar la informació obtinguda. En tots dos estudis es van prioritzar les activitats en funció de la seva importància en tres dimensions: Valoració, Tractament i Monitorització. A mode de síntesi, cal detallar que hi ha gran variabilitat de criteris i intervencions per al maneig de la flebitis. Es destaca la importància de ferramentes de valoració sistemàtica, escollir tractament segons gravetat, i la importància del registre i seguiment visual diari; juntament amb la necessitat de participació del pacient. Emergeixen les bondats del treball interdisciplinari i els equips especialitzats en accés vascular, més una PBE per al maneig dels CVP. Tot i l'augment de publicacions, és clau més investigació, atès l'impacte en la qualitat de les cures i la seguretat del pacient.

[en] The management of peripheral venous catheters (PVCs) is a nursing competence. While the use of PVCs is extensive in the hospital setting, patients are not exempt from complications. Hospital protocols or guidelines on the management of PVCs with respect to PVC-related phlebitis are heterogeneous, nursing knowledge is limited, and the application of evidence-based practice is scarce. The general objectives of this thesis are: 1) To determine the evolution of scientific production and trends on vascular access and phlebitis due to peripheral venous catheterization; and 2) To identify and reach a consensus on PVC management in relation to phlebitis in the healthcare context. Different research methodologies were used with respect to the objectives that were set. Two analytical and descriptive bibliometric analyzes and two expert-based Delphi studies were carried out, at national and international level, to reach a consensus and evaluate PVC management. The international study also included semi-structured interviews with experts. This thesis presents 4 articles in the results section. The bibliometric studies (N= 995 articles and N=1596 articles) revealed a prolonged and sustained interest in venous access and the issue of infections and other complications, as well as the need for monitoring and surveillance by nurses. Areas to be explored in relation to phlebitis were also identified as the basis for consensus studies, as well as emerging areas of study. The national Delphi study included 27 expert nurses and the international study 18 multidisciplinary experts. 4 of whom were interviewed to complement the information obtained. In both studies, activities were prioritized according to importance along three dimensions: Assessment, Treatment and Monitoring. As a synthesis of the thesis, it should be noted that while widely varying criteria and interventions for the management of phlebitis were found, the results of the studies undertaken highlight the importance of the following aspects in the management of PVC-related phlebitis: systematic assessment tools, treatment selection according to severity, the importance of daily visual monitoring and recording, the need for patient participation. Also emerging are the benefits of interdisciplinary work and specialist vascular access teams, and the use of evidence-based practice. Despite the increase in publications, especially internationally, more research is needed to address complications and optimize the management of CVP, given the impact on the quality of care and patient safety.
