Background

Ambulatory and home postoperative analgesia frequently relies on elastomeric pumps, despite known flow variability related to temperature, height and back pressure¹.

Modern electronic ambulatory pumps offer: Programmable intermittent bolus regimens, Delayed starts, Occlusion and air-in-line alarms, Smart-pump safeguards and error-reduction software  to intercept wrong-dose and wrong-rate events²–⁵ Real-world clinician experience with connected electronic systems in outpatient pain management remains limited.

Objective:
To evaluate clinician-reported safety, alarm performance, usability, and satisfaction with a connected electronic ambulatory infusion pump in outpatient and home settings.

Methods
Device: Avoset® Connected Ambulatory Infusion Pump System (Eitan Medical)

Design: Post-market clinical follow-up (PMCF) structured online survey, IRB exempt due to anonymity and post market.

Survey Period: Device use evaluated: Jan–Dec 2024

Participants: Nurses, physicians, pharmacists in USA, UK, France ≥7 prior device uses

Domains Assessed: Care environment, Infusion modes and routes, Alarm recognition and effectiveness, Perceived accuracy, Adverse events, Connectivity utility and Overall satisfaction

Analysis: Descriptive statistics

Results

Respondents Total: 11: USA: 6, UK: 3, France: 2

Practice Setting Ambulatory/outpatient: 7 Homecare: 4

Infusion Characteristics:

Most Common Modes Continuous infusion and Patient-controlled analgesia (PCA) with boluses.

 Routes Intravenous, Perineural and Subcutaneous.

Outcomes: No respondents reported side effects, misuse, or labeling issues. No reported alarm failures or dosing inaccuracies across 11 clinicians in 3 countries. Alarms were effective in drawing attention of user for troubleshooting e.g. resolving line kinks resulting in occlusion alarm for the six clinicians that experienced an alarm. Connectivity was found to be helpful for remote troubleshooting though some minor logging in issues were noted. 

Limitations

Small sample size (n=11)

No direct comparison group

No patient-reported outcomes, only clinician feedback.

Discussion

Connected electronic ambulatory infusion pumps may provide: Enhanced safety compared with elastomeric systems. Real-time alarms for troubleshooting, improved dosing consistency and remote troubleshooting capability with Eitan Insights Platform.

These features may support improved workflow  and potentially better clinical outcomes in outpatient regional anesthesia. Larger, comparative studies are warranted.

Conclusions

Clinicians across three countries reported:

Connected electronic ambulatory infusion pumps represent a promising alternative to

 elastomeric systems in outpatient pain management.
