The answer to dealing with more complex cases is clear: it's training, training, training for the board members.
The increasing complexities exist in the nature of medical conditions: not in the factual happening of the event, causative of damage or of the disability, but rather in the area of medicine. Training will always be required to stay abreast of the various medical conditions out there. It's as simple as that.
No, I don't foresee that the complexity of conditions will enhance or aggravate the backlog. What in fact can create delays is the preparation of the files in relation to expert testimony or expert reports. Often it is the availability of medical expertise--and this is strictly procedural, and almost a societal problem--where vets have difficulty finding an expert to look at their condition. So it's not the complexity of the condition but the availability of the expert to look at the condition that often creates a delay in the preparation of cases.
