Common Causes, Clinical Impact, and Considerations for Prevention
Catheter dislodgement remains a frequent and challenging issue in community and continence care. Patients and carers often ask clinicians, “Why does my catheter keep coming out?” Despite appropriate insertion and initial securement, unplanned catheter movement or removal continues to occur across home, clinic and residential care settings.
In most cases, dislodgement is not the result of incorrect clinical practice. Rather, it reflects the cumulative effect of patient movement, environmental factors, and the limitations of securement methods when used over extended periods outside acute care settings.
Common causes of catheter dislodgement
In community care, catheter dislodgement is rarely attributable to a single event. Instead, it typically develops gradually due to repeated, low‑level forces acting on the catheter and tubing. Common contributing factors include:
- Patient movement, including transfers, walking, repositioning in bed and routine activities of daily living
- Tubing tension, particularly from drainage bags becoming full or catching on clothing, furniture or mobility aids
- Moisture exposure, such as perspiration, bathing or humidity, which may reduce adhesive performance
- Skin integrity issues, including fragile or ageing skin, irritation, or previous adhesive‑related injury
Patients may report that the catheter keeps pulling when moving, even when it appears externally secured. This sensation often reflects subtle catheter movement at the fixation point. Over time, this repeated micro‑movement can contribute to discomfort, urethral irritation, bypassing, or eventual catheter displacement.
Why securement challenges differ in community settings
Securement approaches that are effective in acute care environments may not perform in the same way in community contexts. In hospital settings, patients are closely monitored, reviewed frequently, and typically experience limited mobility. By contrast, community patients are expected to maintain independence, manage personal care, and engage in normal daily activities.
As a result, securement methods used in the community must tolerate:
- Ongoing movement over several days
- Exposure to moisture and temperature variation
- Extended wear times between nursing visits
- Variability in skin condition and patient handling
When these factors are not adequately accounted for, clinicians may observe repeated episodes where a catheter is unintentionally displaced or “comes out again,” despite adherence to standard care principles.
Clinical and operational impact of dislodgement
The consequences of catheter dislodgement extend beyond the immediate need for replacement. From a patient perspective, dislodgement may result in pain, anxiety, and reduced confidence with mobility or self‑care. Some patients may limit activity or attempt to manage the catheter themselves, potentially increasing risk.
For clinicians and services, dislodgement often leads to unplanned reviews, additional visits, after‑hours support, and increased documentation. In community services where resources are limited, these events can place additional strain on care delivery and continuity.
Considerations for reducing the risk of dislodgement
Strategies to help prevent a catheter from coming out again should focus on minimising catheter movement and managing tubing tension, while maintaining skin integrity. Key considerations include:
- Selection of securement methods appropriate for extended wear and patient mobility
- Regular assessment of securement performance and skin condition
- Education for patients and carers on tubing management and early signs of loosening
Purpose‑designed securement devices may assist in this context. Devices such as CathGrip®, for example, are intended to stabilise catheters and tubing while allowing for natural skin movement. When used in accordance with manufacturer instructions and clinical judgement, such devices may help reduce catheter movement and associated tension, particularly in community settings where ongoing activity is expected.
It is important to note that no securement method eliminates risk entirely. Securement should be considered one component of a broader catheter management plan tailored to the individual patient.
Reframing securement as part of catheter management
In continence and community care, effective catheter management extends beyond insertion and maintenance. Securement plays a role in patient comfort, device stability, and service efficiency. A structured, patient‑centred approach to securement selection and review may help reduce avoidable dislodgement events and their associated impacts.
Ultimately, the effectiveness of securement is measured not at the point of application, but over time — as patients move, live, and manage their care in real‑world environments.
