Horizon scanning is becoming particularly important in the medical industry, in the identification and evaluation of emerging technologies. This paper examines the role biomedical engineers may have in horizon scanning new medical technologies and considers whether this is a useful activity for biomedical engineers. A horizon scanning methodology for conducting studies of emerging medical technologies is introduced, consisting of the three main phases of (a) a systematic literature review, in which a set approach is taken to the gathering of information; (b) scanning for publications across a range of different sources; and (c) consideration of the literature in relation to fixed benchmarks to indicate the quality of published information and reported achievements. This methodology has been successfully applied by the authors in a horizon scanning study for the purpose of advising a Government agency on the status of remote patient monitoring technology.

Medical technology in Australian public hospitals has a replacement cost of approximately A$3 billion. The management of this invaluable asset suggests the need for a planning framework to facilitate equipment replacement and acquisition decisions, an accurate inventory of technology assets, and an implementation process to enable prioritisation and the allocation of funds. The authors report on work associated with the initial phases of planning process development and identify issues that need to be resolved in relation to the implementation phase.

This paper presents results of a Capital Equipment Management Plan undertaken at a major acute hospital in Australia. By classifying existing equipment using a threshold replacement value into Major and Minor items, detailed planning information was collected for 527 items of Major equipment representing 80% of the hospital's total equipment stock. A number of meaningful views of this significant asset base are presented, and a prioritisation method used to provide recommendations for future equipment replacement and acquisition for a 5 year planning period. The survey work to identify and document actual equipment items provides a convincing argument for the funding levels required for capital equipment replacement and acquisition, and evidence for the extent of technology reliance in modern health care facilities.

The management of medical technology raises a range of complex issues including those associated with planning, prioritisation, and procurement. In Australia there is a significant and developing interest at National, State, and Hospital levels in issues relating to the effective management of medical technology, with drivers including service planning & cost management, access & equity, and factors associated with the ongoing use of old equipment. Surveys undertaken by the authors and reported elsewhere have now been used to develop a 5 year equipment replacement and procurement model to predict required funding levels. Survey data is also used to assist in the prioritisation of equipment and to identify centralised purchasing opportunities. The data also provides metrics to record the effectiveness of funding programs.

We present a standardized test methodology and results for our evaluation of the Carefusion Alaris PC infusion pump, comprising the model 8015 PC Unit and the model 8100 Large Volume Pump (LVP) module. The evaluation consisted of basic suitability testing, internal component inspection, surface temperature measurement of selected internal components, and critical performance testing (infusion rate accuracy and occlusion alarm pressure) during conditions of typical hyperbaric oxygen (HBO2) treatment in our facility’s class A multiplace chamber. We have found that the pumps pose no enhanced risk as an ignition source, and that the pumps operate within manufacturer’s specifications for flow rate and occlusion alarms at all stages of HBO2 treatments, up to 4.0 ATA and pressurization and depressurization rates up to 180 kPa/minute. The pumps do not require purging with air or nitrogen and can be used unmodified, subject to the following conditions: pumps are undamaged, clean, fully charged, and absent from alcohol cleaning residue; pumps are powered from the internal NiMH battery only; maximum pressure exposure 4.0 ATA; maximum pressurization and depressurization rate of 180 kPa/minute; LVP modules locked in place with retaining screws.
