摘要:

TheJournal of Clinical Engineeringhas conducted a broad scope survey of hospital biomedical and clinical engineering departments throughout the U.S. An earlier report provided salary and job responsibility data. This second report provides, for the first time, numerical data on the administration, facilities, budgets, department workload, personnel workload, employment benefits, quality assurance, and other professional aspects of the departments. The present report represents approximately 6% of all U.S. hospitals, 10% of all U.S. hospital beds, and over $1.1 Billion dollars worth of hospital equipment service responsibilities.Readers are cautioned not to use the statistical averages presented here as standards or guidelines because of the substantial and appropriate differences between departments.Nevertheless, the survey data provide a useful overview of the hospital-based clinical and biomedical engineering field. The survey determined that 58% of hospital biomedical activities are organized as separate departments reporting to hospital administration. From 1984 to 1985, department budgets increased by + 12% overall. While all budget categories increased, wages were the greatest factor (+ 11%). Teaching facilities have substantially higher budgets than non-teaching. Department floorspace increased + 3.2% from year to year. Nationwide, an average of 226 sq. ft. is used per department staff member. Department test equipment increased by + 11.4% from 1984 to 1985. During the same period, the total dollar value of equipment serviced by the departments increased by + 10.5% and the number of devices serviced increased by + 4.8%. Nationwide, the statistically average department serviced 2,220 devices worth $7,068,000. Department employment is growing at + 10.8% per year (teaching department staffs + 7.6%; non teaching + 15.9%). Employment of BMETs grew by + 8.6%; Clinical Engineers by + 11.5%. A measure calledDevices Per Personwas steady at 500 devices per person from year-to-year. A second measure calledBeds Per Personwas, on average, 95 beds per department staff member (lower in teaching, higher in non teaching). Other averages are 136 Beds/BMET; 402 Beds/CE; and 390 Beds/Supervisor. Hospital employment benefits are detailed. Only 23% of departments are now equipped to use telecommunications. Virtually all departments have major Q.C. procedures in place.

摘要:

QRS detection is fundamental for intensive care cardiac instrumentation, such as in arrhythmia recognition or ambulatory recording of cardiac events. Reliable detection of the QRS is necessary in order to obtain accurate measurements of the R-R intervals and QRS width. This paper describes a real-time algorithm for QRS detection based upon the theory of maxima and minima to locate peaks in the digitized ECG. A three-point sliding window is used to determine the presence of peaks and valleys on the signal. Analysis of the difference in amplitude and the time interval between consecutive peaks and valleys allows QRS detection. Thresholds used for detection are adapted according to changes in the amplitude and duration of the previous QRS complexes. Testing was performed with a normal ECG recording contaminated with different levels of added Gaussian noise, giving an average detection rate from 99.7 percent True Positives for a signal-to-noise ratio of 19 dB to 86.5 percent for a low SNR of 7 dB.

摘要:

This paper describes the Biomedical Engineering Department of Newark Beth Israel Hospital. This hospital's extensive involvement in research, heart transplantation, and special technologies has placed unusual demands on the Biuomedical Engineering Department because of the large volume of routine and specialized equipment involved. The 12-person Department is responsible for servicing over 2700 pieces of equipment in 91 various hospital departments, and also offers its services to other local hospitals. Established in 1970, the Department uses a computerized biomedical equipment database program to manage data for repairs, preventive maintenance, and electrical safety.

摘要:

Implementation of a Medical Information System (MIS) in a hospital environment is a complex, problematic, long-term endeavor. St. Vincent Hospital and Medical Center (SVHMC) in Portland, OR, completed the implementation of its base MIS five and one-half years after the original contract was signed. SVHMC prepared the MIS users through an extensive and well-documented training program focused on user competence and user acceptance. Over five and one-half years, 4581 individuals received 9,359 hours of training. Direct training costs were $116,000; total training costs were $317,000. There are many other costs to implement a major MIS project. Reported here are only the costs related to training the system's users. Training costs can be insidious and are often under estimated as institutions plan for large scale MIS projects.

摘要:

In 1982, a system for the continuous, direct processing and display of electronic fetal monitoring data from four separate patients was installed at Sinai Hospital of Detroit. As described in this Journal in 1983, the basic system consisted of an Apple IITMmicrocomputer, with accessories readily available at local computer stores. This software-hardware configuration permitted display of the monitor tracings at the central unit and at remote locations throughout the labor and delivery areas. Printed copies, similar in quality to the bedside originals, were produced on a graphic printer. The computer is now programmed to also interpret this graphic information. Numeric displays of fetal heart rate baseline and variability are updated every two minutes. Warnings of uterine hypertonus, fetal heart rate bradycardia, tachcardia, poor signal quality, and disconnected leads are displayed. Fetal heart rate decelerations are classified by the program as late, variable, early, or late-variable, and designated on the display screen.
