- Construction and validation of a scale of assessment of self-care behaviors with arteriovenous fistula in hemodialysisPublication . Sousa, Clemente Neves; Apóstolo, João Luís Alves; Figueiredo, Maria; Dias, Vanessa Filipa Ferreira; Teles, Paulo; Martins, MMSeveral guidelines recommend the importance of educating the patient about the care of vascular access. Nurses have a key role in promoting the development of self-care behaviors by providing the necessary knowledge to patients, so that they develop the necessary skills to take care of the arteriovenous fistula (AVF). This article describes the process of building a scale of assessment of self-care behaviors with arteriovenous fistula in hemodialysis (ASBHD-AVF). This is a cross-sectional study in which the development, construction, and validation process followed the directions of the authors Streiner and Norman. This is a convenience sample, sequential, and nonprobabilistic constituted by 218 patients. The study was conducted in two stages during 2012-2014. The first phase corresponds to the scale construction process, 64 patients participated, while the second corresponds to the evaluation of metric properties and 154 patients participated. The principal component analysis revealed a two-factor structure, with factorial weights between 0.805 and 0.511 and between 0.700 and 0.369, respectively, explaining 39.12% of the total variance of the responses. The Cronbach's alpha of the subscale management of signs and symptoms is 0.797 and from the subscale prevention of complications is 0.722. The ASBHD-AVF revealed properties that allow its use to assess the self-care behaviors in the maintenance and conservation of the AVF.
- 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.
- Investigating the Effect of a Structured Intervention on the Development of Self-Care Behaviors With Arteriovenous Fistula in Hemodialysis PatientsPublication . Sousa, Clemente Neves; Paquete, Ana Rita Cabral; Teles, Paulo; Barroso, Cristina; Dias, Vanessa Filipa Ferreira; Ribeiro, Olga; Manzini, Carlene Souza Silva; Nicole, Andressa Garcia; Souza, Lara Helk; Ozen, NurtenThis study aimed to assess the effectiveness of a structured intervention on the frequency of self-care behaviors with arteriovenous fistula (AVF) by patients on hemodialysis. This is a quasi-experimental study with pre- and post-measurements. Participants were assigned to an intervention group (IG) (n=48) or to a control group (CG) (n=41). IG patients were subject to a structured intervention on self-care with AVF (SISC-AVF) consisting of both a theoretical and a practical part. After SISC-AVF application, patients in the IG showed better overall self-care behaviors with AVF than patients in the CG (79.2% and 91.4%, respectively, p<.001) as well as better self-care concerning both the management of signs and symptoms (90.1% and 94.4% respectively, p=.004) and the prevention of complications (72.7% and 89.5%, respectively, p<.001). The study results suggest that the SISC-AVF had positive effects on patients in the IG.
- Physical examination of arteriovenous fistula: The influence of professional experience in the detection of complicationsPublication . Sousa, Clemente Neves; Teles, Paulo; Dias, Vanessa Filipa Ferreira; Apóstolo, João Luís Alves; Figueiredo, Maria; Martins, MMVascular access is one of the leading causes of mobilization of financial resources in health systems for people with chronic kidney disease on hemodialysis. Physical examination of the arteriovenous fistula (AVF) has demonstrated its effectiveness in identifying complications. We decided to evaluate the influence of nurses' professional experience in the detection of complications of the AVF (venous stenosis and steal syndrome). The study took place in eight hemodialysis centers between May and September of 2011 in the north of Portugal. Sample was constituted by registered nurses. The nurses involved in the experiment were divided in two groups: those who had more than 5 years of experience and those who had less than 5 years of experience. Ninety-two nurses participated in the study: 34 nurses had less than 5 years of professional experience and 58 had more than 5 years of professional experience. In the practices considered by nurses in the detection of venous stenosis, there were no differences observed between the groups (P > 0.05). In steal syndrome, there were no differences observed between the groups in the practices of the nurses in the detection of this complication of the AVF (P > 0.05). We concluded that professional experience does not influence the detection of venous stenosis and steal syndrome.
- 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.
