The economic impact and multiplier effect of a family practice clinic on an academic medical center

Academic medical centers are facing the need to expand their primary care referral base in an increasingly competitive medical environment. This study describes the medical care provided during a 1-year period to 6304 patients registered with a family practice clinic located in an academic medical center. The relative distribution of primary care, secondary referrals, inpatient admissions, and their associated costs are presented. The multiplier effect of the primary care clinic on the academic medical center was substantial. For every $1 billed for ambulatory primary care, there was $6.40 billed elsewhere in the system. Each full-time equivalent family physician generated a calculated sum of $784,752 in direct, billed charges for the hospital and $241,276 in professional fees for the other specialty consultants. The cost of supporting a primary care clinic is likely to be more than offset by the revenues generated from the use of hospital and referral services by patients who received care in the primary care setting.     

医学图像信息系统研究进展

医学图像信息系统或医学影像存档与通信系统 (PACS)已成为医院信息系统 (HIS)和远程医疗不可缺少的重要组成部分.医学图像是疾病诊断的重要依据,并直接影响诊断的正确性. PACS首次出现在二十世纪七十年代末,是数字成像技术、计算机技术和网络技术对医学影像进行数字化处理的系统.主要用于解决医学影像的采集和数字化、图像的存储和管理、医学图像的高速传输、图像的数字化处理和重现、图像信息与其他信息的集成等五个方面的问题.     

Human errors in medical practice: systematic classification and reduction with automated information systems

We review the general nature of human error(s) in complex systems and then focus on issues raised by Institute of Medicine report in 1999. From this background we classify and categorize error(s) in medical practice, including medication, procedures, diagnosis, and clerical error(s). We also review the potential role of software and technology applications in reducing the rate and nature of error(s).     

The effect on cost of medical care for patients treated with an automated clinical audit system

An automated clinical medical record and audit system was developed to evaluate the effect of modifying physician behavior at the control points in the ambulatory care process and to determine if this change was reflected in patient care cost outcomes. This study compared clinical and cost results of patients in an experimental group, who had the automated record and audit system, to a control group, who had a traditional clinic record without chart audit. Physicians responded to the automated audit suggestions at a rate of 50.25 in the experimental group and 37.3 in the control group. No major differences were observed in clinical outcomes, with the exception of the number of days of hospitalizations and, consequently, the cost of hospitalizations. The experimental group cost for hospitalizations was one-third of the control group and accounted for a majority of the differences in the total annual cost for the two groups.
