This is a symptom of a twofold problem. First, additional staffing and resources for ERs would help to reduce wait times, but I think the more important issue is lack of primary care, which would help patients avoid needing to go to the ER in the first place.
I'm not much of a fan of the way the article is written. Of course there are going to be some cases where a LWBS has serious complications, but locally (and anecdotally), our ER seems to operate more as a walk in clinic at times, and doctors will often see more patients there than they would in a typical clinic day. I feel like the non-emergent visits are likely a considerable part of the 6.8% LWBS rate, and could be offset by a better supply of family physicians. Unfortunately, at least in Saskatchewan, that would require a government willing to do anything whatsoever to help the healthcare system.
