Purpose:
Totally implantable ports require regular maintenance to prevent port-related complications. Manufacturers recommend monthly maintenance port flushes for patients for the life of the port. Previous studies show that extending intervals between maintenance port flushes up to 16 weeks does not increase incidence of port-related complications. To date, no prospective study has been conducted to evaluate the medical safety of extending flush intervals from monthly to every 12 weeks within a heterogeneous disease cohort. Research Question: Is it feasible and medically safe to extend intervals between maintenance port flushes to every 12 weeks in patients with cancer not on active treatment?
Patients And Methods:
This study enrolled oncology and hematology patients who had retained their port following completion of anticancer treatment. Clinical data were extracted for 1,059 participants. The primary end points of this study were the overall number of ports removed and incidence of port-related complications reported between cohorts 1 and 2 (flushes every 4-8 weeks), and cohort 3 (flushes every 12 weeks).
Results:
Data were allocated into three study cohorts on the basis of year and duration between port flushes. No difference was observed in the overall percentage of ports removed because of physician-reported complications across all cohorts (25%-30%). No change in the incidence of port-related complications including suspected infection and malfunction was observed between cohorts 1 and 2 (8%), or cohort 3 (5%).
Conclusion:
Our findings show that extending maintenance port flush intervals to 12 weeks does not increase the incidence of port-related adverse events and is medically safe.
Insights
Extending totally implantable port maintenance flushes to 12 weeks is medically safe for cancer patients not on active treatment. This change does not increase port complications or removal rates, offering a more convenient schedule.
Area of Science:
- Oncology
- Medical Devices
- Patient Care
Background:
- Totally implantable ports require regular maintenance to prevent complications.
- Current recommendations suggest monthly port flushes, but extended intervals have shown promise in prior studies.
Purpose of the Study:
- To evaluate the medical safety and feasibility of extending port flush intervals to 12 weeks.
- To assess port-related complications in cancer patients not on active treatment with extended flush intervals.
Main Methods:
- A prospective study involving 1,059 oncology and hematology patients with retained ports.
- Patients were divided into cohorts based on flush intervals: 4-8 weeks (cohorts 1 & 2) and 12 weeks (cohort 3).
- Primary endpoints included port removal rates and incidence of port-related complications.
Main Results:
- No significant difference in port removal rates due to complications was observed across cohorts (25%-30%).
- The incidence of port-related complications, including infection and malfunction, was similar between cohorts 1 & 2 (8%) and cohort 3 (5%).
Conclusions:
- Extending maintenance port flush intervals to 12 weeks is medically safe.
- This extended schedule does not increase the incidence of port-related adverse events in the studied patient population.
