The equilibrium between supply and demand for red blood cells is increasing unpredictably in many countries. An understanding of trends in blood usage profile and current usage can help predict future trends in demand and to put efforts to reduce use in particular areas. This study helps in analyzing the pattern of red blood cell utilization in a tertiary care hospital.
This retrospective study was conducted in a blood bank, tertiary care hospital over a period of 6 months. All the requests coming to blood bank with information regarding patient's demographic details, diagnosis and indication for transfusion, type of request, blood transfused or returned were collected and reviewed. Crossmatch transfusion (CT) ratio, transfusion index (TI), and transfusion probability were also calculated.
A total of 10,364 patients (20,399 requests) utilized total 32,608 units of blood and its components, out of those 14,195 units of packed red cells units were utilized. March month had maximum number of requests and utilization. Most of the requests for blood were from the inpatients (wards) and were requested and utilized in the age group of 21-30 years with male predominance. Patients in the division of medicine utilized most blood. Although the division of surgery requested most of the blood, on an average, they utilized only one-third of the requested product. Overall, anemia was the most common indication for red cell utilization. In surgical group, spine surgery had a maximum CT ratio. Neurosurgery and hand surgery had the lowest TI in all specialties. Hand surgery and spine surgery had a lowest transfusion probability. Overall, utilization rate in our study was 59.8%.
A regular review of blood unit's usage is very important to estimate the blood utilization pattern in any hospital. Profile of blood utilization will act as indicator for quality management of blood bank.
在许多国家，红细胞的供需平衡正出人意料地增加。了解血液使用情况的趋势和当前使用情况有助于预测未来的需求趋势，并努力减少特定领域的使用。本研究有助于分析三级保健医院的红细胞利用模式。
本回顾性研究在一家血液中心、三级保健医院进行了 6 个月。收集并审查了所有送到血库的请求，这些请求都提供了患者的人口统计学细节、诊断和输血指征、请求类型、输注或返还的血液信息。还计算了交叉配血（CT）比、输血指数（TI）和输血概率。
共有 10364 名患者（20399 次请求）共使用了 32608 个单位的血液及其成分，其中 14195 个单位为浓缩红细胞。3 月份的请求和使用率最高。血液请求大多来自住院病人（病房），年龄在 21-30 岁之间，男性居多。内科的病人使用了最多的血液。尽管外科要求了最多的血液，但平均而言，他们只使用了所请求产品的三分之一。总体而言，贫血是红细胞使用的最常见指征。在外科组中，脊柱外科的 CT 比最高。神经外科和手外科在所有专科中 TI 最低。手外科和脊柱外科的输血概率最低。总体而言，我们的研究中的使用率为 59.8%。
定期审查血液单位的使用情况对于估计任何医院的血液使用模式非常重要。血液使用情况的概况将作为血液库质量管理的指标。
