Introduction: The prolonged permanence of Central Venous Catheter (CVC) in Hemodialysis (HD) is related to an increased risk of complications. The aim of this study was to evaluate duration of use, in days, and reasons for removal of central venous catheter (CVC) in patients with chronic kidney disease undergoing ambulatory hemodialysis in a 10-month follow-up. Methods: This longitudinal, retrospective study was conducted at the hemodialysis unit of a public hospital in southern Brazil, from January to September 2019. Data collection was performed by the researchers using electronic medical records and a spreadsheet of records of patients with chronic kidney disease undergoing hemodialysis by short- and long-term CVC in the study period. The project was approved by the institution's Research Ethics Committee. Results: Ninety-one catheters from 55 patients were evaluated. Thirty-three participants were female (60%), mean age was 55 ± 18 years, and 42 were white (76.3%). Forty-seven (52%) CVCs were short-term, and 70 (76.9%) CVCs were inserted in the right jugular vein. Hemodialysis duration with short-term CVCs ranged from four to 190 days with a median of 47 (21.7-69.3) days, and long-term CVCs ranged from 47 to 1486 days with a median of 231 (95-676) days. The main reason for removing the catheter was replacing it with another CVC, in 17 cases (36.2%). The number of cases of infection or suspected infection was 14 (15.4%). Conclusions: The duration of CVC use was prolonged, which exposes patients to risks. The main reason for removing the CVC was not related to creating an arteriovenous fistula, demonstrating the need to review the care processes aiming to modify and prioritize this practice.

Objective: To develop an educational activity to guide the care of arteriovenous fistulas, from the demands of patients with chronic kidney disease on hemodialysis. Methodology: It was an action-research carried out from March to May 2017, in a dialysis clinic of Fortaleza-CE, Brazil. Data collection occurred with thirteen elderly patients on hemodialysis, through a semi-structured interview, and submitted to content analysis, presenting one thematic category. From the demand presented by the elderly, educational technologies were developed, using a banner and a dummy to guide fistula care. Results: Doubts and inappropriate actions were identified before the intercurrences, such as bleeding, infiltration, rupture, low-flow fistulas, and infections. Therefore, the educational activity facilitated the knowledge exchange about the recommended care in the preservation of the fistula. Conclusion: The educational practice promoted the acquisition of new knowledge for the self-care of arteriovenous fistulas. [ABSTRACT FROM AUTHOR]
