Abstract
Objective:
To confirm established methods and assess bacteriologic and economic consequences of using external portable infusion pumps for the control of cancer pain in the home environment.
Methods:
Sixteen patients with terminal cancer were treated subcutaneously or epidurally with continuous infusions of morphine using external multiday infusion pumps. Bacterial growth in the pumps and costs linked to use in a hospital or at home were assessed. Patients treated at home received 2 pumps weekly, marked A for first use and B for second use, and patients treated in the hospital received 1 pump every fourth day. After use, the remaining solution in the reservoirs was examined for microbiologic contents.
Results:
A total of 317 pumps was used and 211 pumps were cultured (66.6%). Growth was found in 16 (7.6%) (Staphylococcus albus in 13, Escherichia coli in 2, and Candida albicans in 1 pump). There were no significant differences in contamination between pumps used in the hospital or A or B pumps used at home. No patient showed any signs of clinical infection associated with the infusions. The use of multiday devices led to overall cost savings of $284 553 (2.1 million SKr) and a maximum cost savings potential of $379 404 (2.8 million SKr).
Conclusions:
The multiday pump system used and the methods established were found to be safe and bacteriologically satisfactory, as well as cost-effective for both hospital and home use.
