Welcome to this Second Round of the International Delphi Study for the development of a consensus treatment pathway for people with Lumbar Spinal Stenosis!
What is the study about? The aim is to develop an agreed treatment pathway algorithm for patients with lumbar spinal stenosis (LSS) based on research evidence and expert consensus. Expert opinion is required because of the limited research evidence currently available. The First Round of this Delphi study (which you may have participated in) took place in September/October 2019 and focused on selecting appropriate treatments. This Second Round survey will focus on ranking and ordering the selected treatments.
What will I need to do if I participate? This is the second of three survey rounds. As in Round One, the first few questions in this survey are about your clinical and academic background. We will then provide information on the treatments selected by experts who participated in Round One. We will ask you to rank or order these treatments, basing your responses on three different Lumbar Spinal Stenosis clinical phenotypes (as in Round One), this time also considering whether symptoms are mild-moderate or moderate-severe. The three clinical phenotypes are based on different types of symptoms associated with Lumbar Spinal Stenosis. This questionnaire is expected to take around 15 minutes to complete.
The questionnaire will remain open until March 30th 2020. There will be one subsequent survey round after this (summer 2020) to conclude the study. You will be given the opportunity to participate in this final questionnaire in the same way. Participation in all or any of the questionnaires is voluntary.
Why have I been approached? The researchers conducting this study are approaching participants with expertise and experience in managing patients with LSS. We are distributing the survey via spinal research societies, professional bodies, or through local contacts and recommendations. These contact routes will be used for recruitment purposes only, and we will not have any way of knowing who completed each questionnaire. Please share this invitation with any colleagues who might be interested in participating. If this survey is not relevant to you (i.e. if you do not have experience in managing patients with LSS) please still feel free to forward the invitation to others who may have the relevant expertise/ experience.
What will happen next? Once we have analysed the results of this second round questionnaire and the research steering group has held a consensus meeting, we will send out the final round of questionnaires to evaluate the level of consensus for the resulting LSS treatment pathway algorithm.
What are the risks? No significant risks are anticipated for participants other than a small amount of time required to participate in the survey questionnaires. Your personal contact information will not be stored by us, and your completed questionnaire will be entirely anonymous, and stored electronically on a password protected storage drive in line with University of Leeds policy. Only anonymised data will be shared with external collaborators for the purposes of this study. You can withdraw from further participation in the study at any point, however we will not be able to withdraw data already collected from you, as your questionnaire responses cannot be traced to you. Your participation in this survey will be taken to imply consent to include your anonymised responses in future survey iterations and analyses.
What is in it for you? The final outcome of this study will be an expert consensus on an evidence-based, standardised treatment pathway for patients with LSS symptoms. We expect the results of this study to improve understanding of appropriate and standardised care for patients with LSS. We will publish the results of this study in a relevant peer-reviewed journal and share the findings at international spinal conferences.
