摘要:

&NA;The long‐term goal of our research is to develop a methodology and an instrument that would enable noninvasive, continuous, real‐time measurement, as well as long‐term monitoring of tissue ischemia. We have demonstrated that our method, based on impedance spectroscopy, can be used to successfully estimate tissue ischemia in animal models. The objective of this specific portion of our research is to develop the methodology and means to test and identify the optimal non‐invasive electrodes for clinical impedance spectroscopic measurements in the frequency range from 10 Hz to 1 MHz. Many types of electrodes are commercially available for clinical applications, ranging from ECG to TENS. However, they are designed for specific applications and to function only within defined, relatively narrow frequency ranges. When used for wide‐band impedance spectroscopic measurements, they limit the usable bandwidth of the system by introducing significant levels of noise. Unfortunately, electrode manufacturers do not provide data on the performance of their electrodes for wide frequency ranges.The testing protocol was developed and experiments were conducted using our custom‐made PC controlled impedance spectrometer. The electronic noise for each electrode was recorded at thirty frequencies ranging from 10 Hz to 1 MHz. Nine types of electrodes were tested on two human subjects. The results of our studies indicate that, among the tested electrodes, the Blue Sensor Q‐00‐A (manufactured by MedicoTest) is the optimal “off‐the shelf” disposable electrode for clinical impedance spectroscopic studies. It has an average 1.87% noise in the range from 1 kHz — 100 kHz, and provides a bandwidth from 25 Hz to 500 kHz.

摘要:

&NA;Several maintenance options exist to service medical equipment: in‐house staff maintenance, one‐time vendor calls, and both original equipment manufacturer and third party service contracts. Although service contracts provide an annual fixed cost, it is generally the most expensive way to maintain medical equipment. In an effort to reduce healthcare costs, alternatives to service contracts have been pursued. The purpose of this trial was to determine if there is a savings by eliminating selected service contracts in favor of paying vendors for their time and materials (T&M) as necessary. During the trial, service contracts were eliminated and the money from these contracts created the budget used for T&M service. Two trials were conducted at multiple facilities over a year and a half. The first trial lasted six months and eliminated $566,503 in service contracts. The second trial lasted one year and eliminated $1,186,120 in service contracts. The results of the two trials showed that the overall savings for the combined medical centers were $316,895 and $536,506 respectively. In summary, this trial showed that additional money could be saved through the elimination of service contracts for T&M service.

摘要:

&NA;The clinical engineer is defined by the American College of Clinical Engineering as a professional who supports and advances patient care by applying engineering and managerial skills to healthcare technology. The scope of duties of hospital based clinical engineering has expanded from routine preventive maintenance and safety checks. In a fully developed program it now includes a wide range of equipment management functions including long range planning, technology assessment, pre‐purchase evaluation, interaction with other hospital departments, user training, active support of clinical use, government and accreditation compliance, incident investigation, and design. This paper describes these functions and their role in medical equipment management within the hospital.

摘要:

&NA;The Journal of Clinical Engineering conducted its sixteenth annual survey of the salaries paid to biomedical/ clinical engineering and technology personnel in U.S. hospitals. This paper reports the salary and work‐responsibility data obtained from nearly 500 professionals in relationship to: professional certification; region of the U.S.; teaching versus non‐teaching facilities; years of experience; education; union membership; and gender. Data are included on wage increases and job responsibilities. Data are as of 12/31/00 and are compared with data at of 12/31/99. The average BMET I has 5.3 years of experience and earned $31,700 ± $6,500 (nationwide mean ± standard deviation). The average BMET II has 8.9 years of experience and earned $36,900 ± $7,600. The average BMET III has 17.2 years of experience and earned $47,500 ± $10,000. The average BMET Specialist has 14.8 years of experience and earned $53, 600 ± $14,400. The average BMET Supervisor has 17.9 years of experience and earned $53,600 ± $12,400. The average Clinical Engineer has 15.6 years of experience and earned $54,400 ± $17,000. The average CE Supervisor has 19.6 years of experience and earned $62,700 ± $5,300. The average Department Director/Manager has 19.9 years of experience and earned $62,800 ± $17,500.
