The purpose of this survey was to establish baseline information on blood component use in relation to patient diagnoses, procedures, and demographics and to identify patterns of blood use that may be used for blood program planning and transfusion audits.
A cross-sectional survey of the transfusion of blood components in teaching and nonteaching hospitals in central Ontario between September 1991 and August 1992 was carried out. Coders of hospital medical records routinely record demographics, procedures, diagnoses, and other relevant information. A protocol was created by which medical records coders could add the components transfused to the discharge abstract for this study. Red cell use is reported here.
Of the 61 hospitals invited to participate, from which 547,279 patients were discharged during the 12-month period of the study, 45 (74%) agreed to participate. Information was collected on 439,373 discharged patients. Of these, 26,611 (6.1%) received at least 1 unit of red cells. Of a total of 101,116 red cell units transfused, more than 74 percent were used in patients discharged with neoplasms, gastrointestinal diseases, circulatory system diseases, and trauma. High-transfusion-use procedures included operations and procedures on the digestive and cardiovascular systems, diagnostic and therapeutic procedures, musculoskeletal system, and hemic or lymphatic system procedures.
This survey provides baseline blood transfusion information for a specific period that can help determine the need for hospital audits and maximum surgical blood-order schedule guideline reviews. This information is relevant to current recommendations to reduce patient's exposure to blood components. These transfusion data will assist in blood program planning based on known disease trends, demographics, and population changes.
本次调查的目的是建立关于血液成分使用与患者诊断、手术及人口统计学特征之间关系的基线信息，并确定可用于血液项目规划和输血审计的用血模式。
对安大略省中部1991年9月至1992年8月期间教学医院和非教学医院的血液成分输血情况进行了横断面调查。医院病历编码员常规记录人口统计学特征、手术、诊断及其他相关信息。制定了一项方案，病历编码员可据此为本研究在出院摘要中添加所输注的成分。本文报告红细胞的使用情况。
在受邀参与的61家医院中，研究的12个月期间有547,279名患者出院，其中45家（74%）同意参与。收集了439,373名出院患者的信息。其中，26,611名（6.1%）接受了至少1个单位的红细胞输注。在总共输注的101,116个红细胞单位中，超过74%用于患有肿瘤、胃肠道疾病、循环系统疾病和创伤的出院患者。高用血手术包括消化系统和心血管系统的手术及操作、诊断和治疗操作、肌肉骨骼系统以及血液或淋巴系统操作。
本次调查提供了特定时期的输血基线信息，有助于确定医院审计的必要性以及对最大外科用血预订计划指南进行审查。这些信息与当前减少患者接触血液成分的建议相关。这些输血数据将有助于根据已知的疾病趋势、人口统计学特征和人口变化进行血液项目规划。
