Sleep-disordered Breathing Database

This study is creating a confidential database of information from adult patients who have had a sleep study at the Royal Free London NHS Foundation Trust and been diagnosed with a breathing problem linked to sleep, such as obstructive sleep apnoea (OSA) or hypoventilation syndrome. The main goal is to collect important details about their symptoms, body functions, other health conditions, and how well their treatments are working. By gathering this data in an organised way, researchers hope to get a clearer picture of these sleep-related breathing difficulties. This will help them to better understand how these conditions develop and how different treatments affect patients' health over time. It's about learning more to improve care for everyone with these conditions.

Obstructive Sleep Apnoea (OSA)Hypoventilation Syndrome

What is this study about?

This research is setting up a special collection of information, called a database, for adults who visit the Royal Free London NHS Foundation Trust's Sleep and Ventilation Service. The study focuses on people who have had a sleep study and then found out they have a breathing problem that affects their sleep, such as obstructive sleep apnoea (often called OSA) or hypoventilation syndrome.

The idea is to gather various details from these patients in one organised place. This includes things like their symptoms (how they feel), physical measurements (like how their body is working), any other health conditions they might have, and how well their chosen treatments are helping them. By keeping these records carefully, the researchers can look at changes and patterns over time.

Learning from this collected information is really important. It helps doctors and researchers understand more about how these sleep-related breathing problems affect people's health. It also allows them to see what treatments are most effective in the long run. Ultimately, this study aims to improve the care and understanding for all patients living with these types of conditions.

Who may be eligible?

This study is looking for adults aged 18 or over. You would be considered if you have been referred to the Royal Free London NHS Foundation Trust's Sleep and Ventilation Service and have agreed to have a sleep study.

The main requirement is that you understand the study well enough to decide if you want to take part and give your permission. If, for any reason, you are unable to give your informed consent, you wouldn't be able to join the study.

Both men and women are welcome to take part.

What does participation involve?

Taking part in this study primarily involves allowing your medical information, which is already being collected during your routine care at the Royal Free London NHS Foundation Trust, to be added to this secure research database. There are no extra tests, doctor's visits, or medications involved solely for the purpose of this study. You will continue to have your usual appointments, assessments, and treatments as part of your standard care. The researchers will simply be using the information gathered during these routine visits. There is no set total duration for your participation, as your data would be collected as long as you're a patient with the service, or until you decide to withdraw from the study.

Potential risks and benefits

A potential benefit of taking part is that the information collected from you and other patients will help researchers and doctors better understand sleep-related breathing disorders and improve care for future patients. There are no direct medical benefits to you personally, as it doesn't involve any new treatments. The main risk is a very small chance of your personal information not remaining completely confidential, though every effort is made to protect your data. You are free to withdraw your consent and leave the study at any time without giving a reason, and this will not affect your medical care.

Common questions

What is 'sleep-disordered breathing'?

It's a general term for problems where your breathing is abnormal during sleep, like stopping breathing (apnoea) or breathing too shallowly.

Will I have to do anything extra if I join this study?

No, you won't need to have extra appointments, tests, or take new medications. The study uses information from your regular care.

Is my information kept private?

Yes, every effort is made to keep your information confidential and secure in the database, following strict privacy rules.

What is 'Obstructive Sleep Apnoea' (OSA)?

OSA is when your airway repeatedly becomes blocked or narrowed during sleep, causing you to briefly stop breathing or breathe very shallowly.

Can I leave the study if I change my mind?

Yes, you can withdraw from the study at any time without giving a reason, and it won't affect your medical care.
