Blood transfusion is life-saving for patients experiencing acute blood loss and severe anaemia. In low-income and middle-income countries (LMICs), low blood donation rates and unavailability of whole blood and blood components (blood products) impairs timely blood transfusion. To fulfil patient-specific blood orders, a hospital blood transfusion service (HBTS) receives orders from a prescriber for blood transfusion, tests and prepares blood products for the patient. This study sought to describe the current state of LMIC HBTS.
A cross-sectional survey explored LMIC HBTS access to blood products, testing methods, policies and structure. Surveys were administered in English, Spanish, French and Russian, followed by a mixed-methods analysis.
HBTS within LMICs.
From among 124 public and private facilities invited to participate, we received 71 (57%) responses. Of these responses, 50 HBTS from 27 LMICs performed on-site blood transfusions.
Most LMIC HBTS perform blood collection to generate blood products for their patients (36/47, 77%); few relied exclusively on an external supply of blood products (11/47, 23%). The primary reason for blood transfusion was adult anaemia for non-malignant conditions (17/112, 15%). Testing methods varied by gross national income per capita. Blood transfusion delays to patients were common (17/30, 57%) attributed to inadequate blood inventories (13/29, 45%). Other barriers included lack of regular clinician education about transfusion (8/29, 28%) and sustainable financial models for the HBTS (4/29, 14%).
This survey describes the status of HBTS in diverse LMICs, illustrating that the availability of blood products remains a principal problem, requiring HBTS to generate its own facility's blood supply. Currently, blood shortages are not reported as a patient-specific adverse event making systematic tracking of delays in transfusion difficult. These findings highlight areas for further exploration related to the lack of available blood inventories for transfusions at HBTS in LMICs.
对于急性失血和严重贫血的患者,输血是救命的。在低收入和中等收入国家(LMICs),低献血率以及无法获得全血和血液成分(血液制品)会影响及时输血。为了满足患者特定的输血订单,医院输血服务(HBTS)会从医嘱中收到输血、检测和准备患者血液制品的订单。本研究旨在描述 LMIC HBTS 的现状。
横断面调查探讨了 LMIC HBTS 获得血液制品、检测方法、政策和结构的情况。调查以英语、西班牙语、法语和俄语进行,随后进行混合方法分析。
LMIC 中的 HBTS。
在受邀参与的 124 家公立和私立机构中,我们收到了 71 份(57%)回复。在这些回复中,有 50 家来自 27 个 LMIC 的 HBTS 进行了现场输血。
大多数 LMIC HBTS 会进行血液采集以生成供患者使用的血液制品(36/47,77%);很少有 HBTS 完全依赖外部血液制品供应(11/47,23%)。输血的主要原因是成人非恶性疾病贫血(17/112,15%)。检测方法因人均国民总收入而异。患者输血延迟很常见(17/30,57%),原因是血液库存不足(13/29,45%)。其他障碍包括缺乏关于输血的常规临床医生教育(8/29,28%)和 HBTS 的可持续财务模式(4/29,14%)。
本调查描述了不同 LMIC 中 HBTS 的现状,表明血液制品的供应仍然是一个主要问题,需要 HBTS 生成自己机构的血液供应。目前,由于不是将血液短缺报告为患者特定的不良事件,因此难以对输血延迟进行系统跟踪。这些发现突出了在 LMIC 中 HBTS 缺乏可用于输血的血液库存方面进一步探讨的领域。
