Core Viewpoint - The National Health Commission of China reported a decline in voluntary blood donations globally, with China facing significant blood supply and demand imbalances, leading to increased clinical blood needs and ongoing regional blood shortages in 2024 [1][2]. Group 1: Blood Donation Trends - There has been a noticeable decrease in voluntary blood donations over the past two years due to various factors [1]. - The slogan for World Blood Donor Day 2023 is "Donate Blood, Share Hope, Save Lives," aimed at encouraging more people to participate in voluntary blood donation activities [1]. Group 2: Blood Fee Waiver Initiative - The National Health Commission has launched the "Blood Fee Waiver with One Visit" project to facilitate blood donors in processing fee waivers online, regardless of location [2]. - The initiative utilizes the "National Electronic Voluntary Blood Donation Certificate" WeChat mini-program to streamline the application process for cross-province fee waivers, with thousands of applications processed to date [2]. - Efforts are being made to enhance the interconnectivity of military and civilian blood donation systems, ensuring timely and comprehensive recording and querying of donation information [2]. Group 3: Health and Safety of Blood Donors - Individuals meeting the national health standards for blood donors can participate in blood donation, which includes health inquiries, physical examinations, and blood tests to ensure donor safety [3]. - Blood must maintain traceability throughout the donation, preparation, testing, and clinical transfusion processes, with results communicated to donors via SMS or WeChat [3]. Group 4: Impact of Blood Donation on Health - Blood donation has minimal impact on the total blood volume in the body, and any temporary dizziness or fatigue experienced by some donors is a normal physiological response [4]. - Post-donation, the body quickly replenishes blood volume, and normal dietary habits are sufficient for recovery, with recommendations to stay hydrated and avoid strenuous activities for 48 hours [4].
