Abstract

Background: Infusion sets for use with insulin pumps are recommended for use for 2 to 3 days to avoid local skin reactions, for example, to the insulin formulation and preservatives like meta-cresol. However, many patients use the catheters longer for economic reasons. We performed this study to investigate the tolerability of 2-day use of infusion sets in comparison to 4-day use in a real-world setting. Methods: This prospective randomized controlled crossover study with 2 × 3-month observation periods was performed with 24 type 1 patients. At baseline, patients were trained on the use of the infusion system (Medtronic /Mio® or inset™ II) and randomized to any of the 2 treatment sequences. Observation parameters included glycemic control, frequency and nature of device-related, and procedure-related adverse events and patient preference. Results: The per-protocol analysis was performed with 22 patients (5 men, 17 women, age 39 ± 11 years, BMI 27.0 ± 3.5 kg/m2). The number of catheter related adverse events was 290 with 2-day use versus 495 with 4-day use ( P < .05). The overall number of treatment related events was 750 with 2-day use versus 934 with 4-day use ( P < .001). There was no difference in glycemic control between the treatment arms. Treatment satisfaction was higher with 2-day use (very high/high satisfaction: 90.4% versus 4 day-use: 77.3%, P < .05). Conclusion: Our results demonstrate that using the infusion sets for a longer usage period of 2-3 days resulted in a clinically relevant increase in treatment-related tolerability problems. Patients should be trained and encouraged not to use insulin pump infusion sets for a longer than the recommended time period.

  • Longer IIS wear duration >3 days has been associated with higher number of catheter-related adverse events, including hyperglycemia, site reactions, and silent occlusions.

    “In addition, longer IIS wear duration >3 days has been associated with higher number of catheter-related adverse events, including hyperglycemia (blood glucose >250 mg/dL), site reactions, and ''silent occlusions.''7,12,17”

    From Frequency and Detection of Insulin Infusion Site Failure in the Type 1 Diabetes Exchange Online Community (2023) · cites this paper as [7]

    The Results report more catheter-related adverse events with 4-day than 2-day wear, including hyperglycemic events above 250 mg/dL and injection-site reactions (page unavailable). The paper mentions occlusions as a potential technical problem and says used sets were inspected for them, but our copy does not identify increased *silent* occlusions with longer wear. (LLM, conf=0.87)

  • IIS failure is most often attributed to cannula-associated issues (kinking, occlusion, and dislodgement) or insertion site inflammation/infection.

    “IIS failure is most often attributed to cannula-associated issues (kinking, occlusion, and dislodgement) or insertion site inflammation/infection.2,6,7”

    From Frequency and Detection of Insulin Infusion Site Failure in the Type 1 Diabetes Exchange Online Community (2023) · cites this paper as [7]

    The Discussion (page not provided) identifies kinking or bending of the cannula as this study’s most frequent failure event and reports blockage as a common infusion-set problem in a cited survey. The paper also describes sets pulling out and insertion-site irritation, but the passages do not establish inflammation or infection as among the most frequent causes of IIS failure. (LLM, conf=0.84)

    Experimental — accuracy not yet measured
  • Patients routinely insert a new CSII catheter every 2-3 days because insulin absorption into the circulation becomes more variable and less reliable over time.

    “Patients routinely insert a new catheter every 2–3 days due to increasing variability of insulin absorption over time.”

    From Detailed Analysis of Insulin Absorption Variability and the Tissue Response to Continuous Subcutaneous Insulin Infusion Catheter Implantation in Swine (2017) · cites this paper as [9]

    The Discussion recommends changing infusion sets every 2–3 days, and the introductory passage under Abstract says longer use appeared to change insulin absorption and worsen glycemic control. The paper does not establish increasing variability of absorption as the reason patients routinely change catheters; it also gives skin reactions and other adverse effects as reasons for the recommended interval. (LLM, conf=0.85)

    Experimental — accuracy not yet measured
  • Standard insulin infusion sets should be changed every 2 to 3 days to prevent or reduce adverse events.

    “Standard IISs should be changed every 2 to 3 days,1–3 regardless of rapid-acting insulin used,4 to prevent or reduce adverse events (e.g., site failure resulting in hyperglycemia, skin inflammation, infection or pain at the IIS site, adhesive patch failure, etc.).”
  • Early feasibility and pilot IIS studies showed significant device-related adverse events that included increased hyperglycemia and functional or mechanistic issues with IIS use during longer durations of wear.

    “While early feasibility and pilot IIS studies showed significant device-related adverse events that included increased hyperglycemia and functional or mechanistic issues with IIS use during longer durations of wear,1–3”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
