Advantages in Management and Remote Monitoring of Intravenous Therapy: Exploratory Survey and Economic Evaluation of Gravity-Based Infusions in Finland.

INTRODUCTION

Intravenous infusion therapy is a common and challenging invasive treatment procedure in hospital wards. Administration mistakes can have serious, even life-threatening, consequences. The Monidor solution was developed to help nurses administer gravity-based infusions and monitor them remotely, to avoid complications and reduce workload. Its real-world effects and economic consequences were unknown.

METHODS

An exploratory survey was carried out to estimate the potential impact of the Monidor solution on events and nurse time use. At the end of their shift, nurses estimated effects in terms of routine room visits avoided, prevention of complications, and impact on nurse time requirements. Linear regression was applied to estimate predictors of time freed. A health economic model was developed to evaluate economic consequences and to calculate the net return on investment for a hypothetical hospital ward. A 1-month time horizon was used, and discounting was not applied.

RESULTS

A total of 216 responses were obtained from 6 Finnish hospitals, from a total of 15 wards, and 56.3% of nurses found that the Monidor solution freed nurse time, while < 3.5% experienced additional time requirements. Per nurse shift, the Monidor solution avoided on average 2.064 routine room visits, helped detect end of infusion 1.340 times, and led to 5.045 min of time freed. One routine visit avoided was associated with 2.453 min of time freed in the linear regression. In the conservative setting, the freed monthly capacity in the hypothetical ward amounted to €1270.90 per month (year 2021), yielding a return on investment of 2.63. Uncertainty of linear regression coefficient values was identified as a driver of uncertainty in sensitivity analysis, with return on investment ranging from 1.55 to 3.71.

CONCLUSIONS

The study demonstrated that management and remote monitoring with the Monidor solution frees nurse time and reduces routine activities associated with gravity-based intravenous infusions. These findings could be confirmed in a comparative empirical study.
