Patency and Complications of Hemodialysis Arteriovenous Fistulas in a Low-Income Setting: A Cross-Sectional Analysis from Bogotá - Protocol and Data

This dataset contains anonymized clinical, demographic, laboratory, and surgical data from 204 adult patients with chronic kidney disease undergoing hemodialysis who received an arteriovenous fistula (AVF) for vascular access at the Renal Unit of Hospital Occidente de Kennedy, a tertiary public care hospital in Bogotá, Colombia, between June 2019 and July 2024.
The data were collected retrospectively from institutional electronic and physical medical records as part of a descriptive cross-sectional study evaluating AVF patency and complications in a low-income population. Variables include patient sociodemographic characteristics (age, sex, socioeconomic status, educational level), comorbidities, laboratory values, dialysis history, previous vascular access use, AVF anatomical and surgical characteristics, pharmacological treatment, and clinical outcomes such as one-year fistula patency and access-related complications (including thrombosis, failure to mature, infection, distal ischemia, and aneurysm formation).
This dataset was created to support the analysis of factors associated with AVF durability and complications in resource-limited settings. It may be useful for researchers studying vascular access outcomes, hemodialysis care, chronic kidney disease management, health disparities, and surgical outcomes in low- and middle-income countries.

本数据集包含2019年6月至2024年7月期间，于哥伦比亚波哥大三级公立医院奥肯登肯尼迪医院（Hospital Occidente de Kennedy）肾脏科就诊的204例慢性肾脏病成年血液透析患者的去标识化临床、人口统计学、实验室及外科数据，所有患者均为建立血管通路接受了动静脉内瘘（arteriovenous fistula, AVF）手术。
本数据集的数据通过回顾性调取机构电子与纸质病历收集而来，属于一项评估低收入人群动静脉内瘘通畅性与并发症的描述性横断面研究的组成部分。数据集涵盖的变量包括患者社会人口学特征（年龄、性别、社会经济地位、受教育程度）、合并症、实验室检测指标、透析病史、既往血管通路使用情况、动静脉内瘘解剖与手术特征、药物治疗方案，以及临床结局指标，如内瘘1年通畅率、通路相关并发症（包括血栓形成、成熟失败、感染、远端缺血及动脉瘤形成）。
本数据集旨在支撑资源受限地区动静脉内瘘持久性与并发症相关影响因素的分析研究，可服务于中低收入国家中开展血管通路结局、血液透析护理、慢性肾脏病管理、健康差异及外科结局相关研究的科研人员。
