Qualidade em acessos vasculares periféricos: Avaliação das propriedades métricas do miniquestionário sobre cateter intravenoso periférico – Versão Português do Brasil.

Abstract

Introduction – Vascular access is a widely used procedure in healthcare, and evaluating its quality is essential to prevent complications such as early failures and issues related to the peripheral intravenous catheter (PIVC). Healthcare professionals need to have mastery of infusion therapy based on evidence-based recommendations, as well as integrate quality management strategies into their practice. Regarding PIVC care, there are several ways to establish improvements that will impact clinical practice, one of which is the application of tools to assess the quality of care related to PIVC. Objective – To evaluate the measurement properties of validity and reliability of the Mini-questionnaire on Peripheral Venous Catheter – Brazilian Portuguese version (PIVC-miniQ-PB). Material and Methods – A methodological study with a quantitative, observational, and prospective approach was conducted in a public teaching hospital in Minas Gerais. Conducted in two stages, validation of the instrument’s metric properties. Concurrent and predictive validity, through a longitudinal study; and discriminative construct validity were evaluated by comparing the overall scores of PIVC-miniQ-PB across different inpatient sectors, using the Student’s t-test. Additionally, interobserver reliability was assessed using the Kappa coefficient and the Intraclass Correlation Index. The study population consisted of hospitalized patients with PIVC. Data were collected using three instruments: PIVC evaluation and monitoring tool, PIVC-miniQ-PB, and the Portuguese Phlebitis Scale. Data were analyzed using IBM® SPSS® software version 25. The study adhered to all necessary ethical considerations. Results – The study evaluated 315 patients, mostly men (60.6%) and white (49.8%), aged between 18 and 96 years (M=58.5, SD=17.56), mainly hospitalized in the Medical Clinic (69.8%). The quality of PIVC care was monitored until catheter loss, with significant drops in the number of participants observed: 23% on the second day, 68% on the third day, and nearly 90% from the fourth day onwards. Construct validity revealed higher scores on the PIVC-miniQ-PB for patients hospitalized in the ICU compared to wards, with significant differences (p<0.05) in the first two evaluations. The instrument demonstrated high reliability (ICC=0.96; p<0.001) and good correlation with the Portuguese Phlebitis Scale, confirming its robustness and utility in assessing the quality of PIVC care. Discussion: In the original study, independent evaluators in two Norwegian hospitals found that the intraclass correlation coefficient between raters was significant, similar to the findings of this study. Other studies using the PIVC-miniQ have enabled healthcare professionals to identify, monitor, and intervene in a standardized way, minimizing risks and improving the clinical decision-making process. Conclusion – The PIVC- miniQ-PB demonstrated satisfactory metric properties, has proven to be valid and reliable for assessing the quality of care for peripheral venous catheters implantation in the Brazilian context.
