MEDICAL PRODUCTS MARKETING SERVICES
Methodology for Infusion Pump Audit
Since 1984, Medical Products Marketing Services (MPMS) has maintained a database of the inventory of electronic flow control devices in US hospitals. The panel is balanced by: geography and hospital bed size. Audit updates are conducted by interview with multiple hospital sources. Although there is a higher cost associated with this approach, healthcare professionals are used as phone interviewers because they have consistently demonstrated higher recruitment rates and greater accuracy in data collection.
In this case, we collect data by 6 metrics:
Month/year of installation
Installation type: New Placement, Replacement or Removal
One-to-one linkage of replacement information
Removal history, where applicable
Location/department and acquisition types are audited, but limited
The definitions of count parameters and terms used in this report are:
Increase in the installed pumps from additions to inventory.
Devices already installed and calibrated for use by the end of the reporting period are counted as the installed base.
Devices removed from inventory and not replaced. A hospital’s inventory is directly reduced by removal of these items.
New placement of pumps that increase the installed base. These are newly acquired equipment that do not replace existing units.
Replacements are new devices that upgrade existing equipment, either replacing an item from the same manufacturer or switching to a competitor.
The key to market analysis is to analyze the activity within a period, which is defined as the impact on the installed base of the components listed above and to analyze the market segments (bed size and region) in which this activity took place.
