- Effects of demographic and clinical character on differences in self‐care behavior levels with arteriovenous fistula by hemodialysis patients: An ordinal logistic regression approachPublication . Sousa, Clemente Neves; Teles, Paulo; Paquete, Ana Rita Cabral; Dias, Vanessa Filipa Ferreira; Manzini, Carlene Souza Silva; Nicole, Andressa Garcia; Sousa, Rui André Saldanha Santos; de Souza, Lara Helk; Ribeiro, Olga; Lira, Marta Nunes; de Queiroz Frazão, Cecília Maria Farias; Ramos, Vânia Pinheiro; Leal, Luciana; Ribeiro, Rita Cássia Helú Mendonça; Magalhães, Anna Luiza Pereira; de Sá Basílio Lins, Sílvia Maria; Mendonça, Ana Elza Oliveira; Delgado, Millena Freire; Pressi, Maira Maria Trevisan; Pressi, Nicole Trevisan; Campos, Luís; Campos, Tiago; Gonçalves, Diana; Ribeiro, Edgar; Ozen, NurtenIntroduction: Hemodialysis (HD) patients should be trained to develop selfcare behaviors in order to prevent and preserve their arteriovenous fistula (AVF). The aim of this study was identifying the factors that affect the levels of self-care behavior with AVF by HD patients. Methods: A cross-sectional study was conducted involving 89 patients. Results: Self-care levels were negatively affected by patients' location (Azores) and positively affected by marital status, education, employment, AVF duration, and absence of complications with the AVF. Concerning the management of signs and symptoms, self-care levels were negatively affected by patients' location. Regarding prevention of complications, self-care levels were negatively affected by age and marital status and positively affected by marital status, employment, chronic kidney disease etiology, AVF duration, and previous AVF. Conclusion: Further studies are required in order to confirm whether the considered factors affect levels of self-care behaviors with AVF, or whether other factors are needed as well.
- How to choose the appropriate cannulation technique for vascular access in hemodialysis patientsPublication . Sousa, Clemente Neves; Teles, Paulo; Ribeiro, Olga; Sousa, Rui; Lira, Marta Nunes; Delgado, Elisabete; Oliveira, Debora; Campos, Luís; Fernandes, Filipa; Moura, Sandra Cristina Mendo; Delgado, Millena Freire; Sá, Tiago Gomes; Teixeira, Sílvia Mónica Pereira; Souza, Lara Helk; Ribeiro, Rita Cássia Helú Mendonça; Oliveira, Gabriela Fernanda Neves; Mendonça, Ana Elza Oliveira; Ozen, NurtenThe cannulation technique is important for the survival of the arteriovenous access. Choosing the appropriate technique is a complex decision. Such choice must be customized to patients, considering their characteristics, the type of arteriovenous access and the experience of the hemodialysis team. We describe seven items that can help nurses to identify the appropriate cannulation technique: type of arteriovenous access; drainage vein; hygienic self-care profile; experience of the nursing staff in the cannulation technique and nurse-to-patient ratio; hemodialysis treatment method; patient's condition; and patient's decision. Such items can help nurses in decision-making on the "ideal" cannulation technique for each patient.
- Scale of Assessment of Self-Care Behaviors with Arteriovenous Fistula in Hemodialysis: A Psychometric Study in BrazilPublication . Lira, Marta Nunes; Sousa, Clemente Neves; Wanderley, Maria Carolina Medeiros; Pessoa, Natália Ramos Costa; Lemos, Kelly Cristiane Rocha; Manzini, Carlene Souza Silva; Nicole, Andressa Garcia; Morais, Sheila Coelho Ramalho Vasconcelos; Frazão, Cecília Maria Farias de Queiroz; Ramos, Vânia Pinheiro; Teles, Paulo; Ribeiro, Olga; Dias, Vanessa Filipa Ferreira; de Souza, Lara Helk; Ribeiro, Rita Cássia Helú Mendonça; Magalhães, Anna Luiza Pereira; de Sá Basílio Lins, Silvia Maria; Pressi, Maira Maria Trevisan; Dourado, Polyana Bezerra Mendonça; Delgado, Millena Freire; Mendonça, Ana Elza Oliveira; Pinheiro, Jacielly Andes Araújo; Ozen, NurtenThe purpose of this study was to evaluate the psychometric properties of the Brazilian Scale for the Assessment of Self-Care Behaviors with Arteriovenous Fistula in Hemodialysis. Cross-sectional validation study, followed the recommendation provided by Sousa and Rojjanasrirat. Content validity, explanatory and confirmatory factor analyses used to check validity and Cronbach's alpha was the reliability measure. Three hundred hemodialysis patients with arteriovenous fistula were included in the study. The expert committee assessed the content validity. Exploratory factor analysis confirmed the same two-factor structure found for the original scale, explaining 60.10% of the variance. Such solution was checked by confirmatory factor analysis with Cronbach's alpha equal to 0.920, 0.810, and 0.884 for the overall scale, the self-care in management of signs and symptoms and the self-care in prevention of complications subscales respectively. The scale has good psychometric properties to assess self-care behaviors and can be used with Brazilian patients on hemodialysis with arteriovenous fistula.
