WHAT HAS BEEN THE IMPACT OF MDT MEETINGS?
![Page 12: MDT meetings: an idea whose time has gone? Alastair J Munro … · 2017. 3. 3. · process results in a recommendation, not a decision. Ensure that MDTs operate within an appropriate](https://reader036.vdocuments.us/reader036/viewer/2022062605/5fd97622500e945c2c11db4c/html5/thumbnails/12.jpg)
Colorectal MDT performance
• Rate of compliance with standards: 91% (median)
• Rate of “immediate risks” 8/165: 5%• Rate of serious concerns 55/165: 33%
![Page 13: MDT meetings: an idea whose time has gone? Alastair J Munro … · 2017. 3. 3. · process results in a recommendation, not a decision. Ensure that MDTs operate within an appropriate](https://reader036.vdocuments.us/reader036/viewer/2022062605/5fd97622500e945c2c11db4c/html5/thumbnails/13.jpg)
immediate risks and serious concerns
o Lack of Clinical Oncology capacity, meaning that treatment decisions are taken without oncology input
o Difficulties of collection of robust clinical MDT data, due to resource issueso Anal cancer pathways outwith IOG agreed configurationso Lack of CNS capacity, impacting on workload and availability at significant
points in pathwayo Not all patients offered laparoscopic surgeryo Inequities in patient pathway and support across MDTs within the same
Trusto Impact of increased workload, including endoscopy capacity, theatre
capacity and surgical bedso Cancelation of MDT meetings due to MDT coordinator absenceo Surgeons not undertaking required 20 operative procedures with curative
intent

“All these observed variations in radiotherapy usage were seen despite the routine weekly colorectal MDT meetings, which occur across the NHS, in which clinical and radiological staging investigations, including pelvic MRI, are reviewed to determine the selection of patients for preoperative treatment. MDTs are, therefore, adopting very different treatment strategies. How can this wide variation in radiotherapy usage be explained?”

Problem Proposal Intended effect
Costs Restrict face-to-face MDT discussions to complex or unusual problems
Decrease the direct and indirect costs
Limited evidence for effectiveness Randomised controlled trials using a step wedge design,
Demonstrate relative effectiveness of different models
Recruitment to clinical trials and adherence to guidelines
Electronically mediated system would automatically capture information and make suggestions
Improved recruitment to clinical trials and adherence to guidelines.
Clinicians lack confidence
Use suitable gating mechanisms for referral to discourage the abuse of the MDT process by lazy clinicans
Ensure that the MDT is not a refuge for shirkers
Limited educational value Automatic capture of high-quality data generates an electronic archive of knowledge and experience: an educational resource.
An archive for each team that can be used for education and audit.
Medico-legal ambiguities Clarify the medico-legal position by insisting that the MDT process results in a recommendation, not a decision.
Ensure that MDTs operate within an appropriate legal framework
Committees for impersonalised medicine:
A web-based system would permit contributions from clinicians who actually know the patient
Better representation of patients views
Unnecessary delay Discussions could take place at any timeReduction in the interval between diagnosis and starting definitive treatment
Flurry of emails following each MDT.
The emails (or other electronic communication) would be part of the MDT process Flexibility
Ritual and disengagement
Discussion is less likely to become formulaic: audit trail and the Hawthorne effect.
Discussions become more open and varied
Primary care excluded A more flexible web-based system would allow GPs instant access to, and (potentially) participation in, discussion.
There would be greater involvement of primary care
