A little know-how can help reduce service costs.

Hospital executives may not always know exactly how much their institutions spend each year on clinical equipment maintenance, but they do know their costs are too high, according to a new survey sponsored by a Milwaukee-based biomedical engineering contractor. The survey's sponsor says a carefully administered cost-reduction program for equipment maintenance can reap about a 20 percent savings.

Supply prices to increase slightly.

Expect hospital supply prices to increase by about 3 percent to 4 percent during 1991, says the new economic forecast from the Joint Purchasing Corp. (JPC), New York City. JPC's report may help reduce the uncertainty for those making supply price forecasts during the current recession. The Economic Forecast and Budget Impact Report presents economic information from industry analysts and publishes the data in a single volume. The JPC forecast can be used as a guide to help determine price changes; however, it's also important to consider changes in consumption, utilization, and quality when using the report, says JPC's president.

CEOs begin to share control of IS purchases.

Although senior executives and departmental staff frequently play a role in information management purchasing decisions, chief executives still have accountability for final decision making--especially when the purchases involved are capital-intensive. However, according to an exclusive survey of executives conducted by Hospitals, things are slowly beginning to change.

Autoregulation of beat frequency in respiratory ciliated cells. Demonstration by viscous loading.

As opposed to the virtually constant load exerted by water on the cilia of ciliated protozoa, the hydrodynamic load on respiratory cilia can undergo broad variations because of changes in the rheologic properties of mucus. When water-rowing ciliated cells are exposed to increased viscosity (1 to 50 cP), their beat frequency decreases exponentially. According to Newton's fluid dynamic theory, this outcome is expected for an engine that generates constant force. However, the findings reported here indicate that when mucus-propelling respiratory ciliated cells are exposed to high viscous loads, ranging from 12 to 150 cP, the frequency of ciliary beat decreases only slightly, whereas the beat amplitude remains virtually constant. These observations suggest that ciliated cells of the respiratory tract have a functional reserve that allows them to autoregulate their mechanical output in response to the changes in viscosity to which they are normally exposed in the airway.

Contract language can ensure satisfaction.

A significant number of hospitals are in legal wrangles with computer vendors because they are unsatisfied with the computer systems they've purchased. Many of these disputes arise because the hospitals signed contracts that were not in their favor.

Computers help keep patient files confidential.

File folders stuffed with papers documenting a patient's hospital stay can be an administrative nightmare. Such medical records are easily misplaced and might already be checked out when they need to be reviewed. In addition, because so many eyes glance at such files, confidentiality is a problem. That's why some hospitals are purchasing information systems for their medical records departments.
