Dear member of the International Society of Paediatric Oncology,

We are writing to invite you to participate in a survey on Central Venous Access Device (CVAD) practice in paediatric cancer care.

This research aims to explore the current CVAD selection, insertion, management, removal, and complication management practices in paediatric cancer care on a global scale. The information you will give us will help to understand the current situation and identify the variations in usual practice, particularly in the lower middle resource contexts, for future management changes.

You can participate in this survey If you are a clinician who usually manages CVADs in your paediatric cancer setting.

• Central Venous Access Devices (CVADs) is a device that is inserted into the body through a vein to enable the administration of fluids, medication, and other therapies. CVADs can be inserted into the subclavian or jugular vein (implanted ports, tunnelled catheters) or can be inserted into one of the peripheral veins of the upper extremities, called peripherally inserted central catheters (PICCs).

 If you do not use Central Venous Access Devices (CVADs) in your oncology practice, please share your current practice on cancer treatment on the first page.

The survey involves answering about 40 questions about your practice and CVAD management. Completing the survey could take around 20 minutes. You are free to withdraw at any time. To do this, simply close the browser window that the survey is presented on.

We do not expect any direct benefits to you personally from completing this survey. However, your response will benefit our understanding of the current situation to we can identify future areas of priority. We are not aware of any risks to participants in the research.

All data will be anonymous and confidential. All data will be de-identified and stored on the password-protected web-based data management system. All data will be destroyed 15 years after completion of the study/publication of study findings and then destroyed according to our institutional policy.

We would like to thank you in advance for your time and contribution to this important research project.
