A paperless electronic spirometer/diary instrument has been employed in a home monitoring programme for lung and heart-lung transplant patients at the University of Minnesota. The monitoring programme is part of a long term study to develop a system which will detect the earliest signs of developing rejection or infection in the transplanted organs. It is based on patient daily self-measurements of standard spirometry, vital signs, and symptoms recorded at home and transmitted weekly to the study data center over the telephone using a modern built into the instrument. This report summarizes adherence behaviour for 41 subjects enrolled in the study over a 12 month period. The number of subjects from whom home data has been received each week was used to measure adherence at the subject level. The number of records received each week measured adherence at the daily recording level. A data record consists of a daily set of spirometry, vital signs, and symptom values from a given subject. Approximately 82% of subjects transmitted records each week, over the 52 week review period. There was an average of 4.5 records received each week from each subject. Transmitted records had missing vital sign or symptom items in less than 2% of cases, spirometry data was always present. This evaluation showed than lung transplant recipients are willing and able to use a home-monitoring instrument, and that basic spirometry, data entry, and data transmission can be performed satisfactorily.
明尼苏达大学在一项针对肺移植和心肺移植患者的家庭监测项目中使用了无纸电子肺活量计/日记仪器。该监测项目是一项长期研究的一部分，旨在开发一种系统，以检测移植器官排斥或感染的最早迹象。它基于患者在家中对标准肺活量测定、生命体征和症状的每日自我测量，并使用仪器内置的调制解调器每周通过电话传输到研究数据中心。本报告总结了41名参与该研究的受试者在12个月期间的依从行为。每周收到家庭数据的受试者数量用于衡量受试者层面的依从性。每周收到的记录数量衡量每日记录层面的依从性。数据记录包括来自给定受试者的一组每日肺活量测定、生命体征和症状值。在52周的审查期内，约82%的受试者每周传输记录。每个受试者每周平均收到4.5条记录。传输的记录中，生命体征或症状项目缺失的情况不到2%，肺活量测定数据始终存在。该评估表明，肺移植受者愿意并能够使用家庭监测仪器，并且基本的肺活量测定、数据录入和数据传输都可以令人满意地进行。
