By right, being an investigation, there really should not be such a long wait for a colonoscopy. After all, one of the main reason the test is being done is to exclude a bowel cancer.

Why should a public patient wait for such a long time for an investigation? Does anyone have to wait more than 4 weeks for a blood test or any Xray?

Currently there are so many patients on public waiting lists all over Australia.  Mathematically, I cannot see how this would get any shorter if the current situation persist. In fact, it will only get longer as the population ages, more and more people leave private insurance and hospital budgets become tighter.  Also in public hospitals, the throughtput is much less than in  a private endoscopy centre for a number of reasons including:

1. Hospital bureaucracy slowing turnover of patients

2. Working culture

3. Need for trainee anaesthetists and surgeons/gastroenterlogists to learn hands on

4. Financial model in public hospitals do not given any incentives for the hospital to do more scopes(they would go over budget, they can only have a certain percentage of patients are day cases, and only do a certain number of scopes a year) nor do they give incentives for specialists(paid by the hour on a rate far less than what one gets privately, often moral is low due to hospital bureaucracy, most are staying on only out of a duty to care for their patients and to teach the trainees) to increase throughput

Hence in the public hospitals, the average colonoscopes booked to a half day list(with registrars) may be about 6-7 while privately one can have 8-10 cases on a half day list.(Some private centres do even more than that – but doing  a colonoscopy too quickly is also not good as polyps may be missed.  Ideally, 30min should be allocated for each colonoscopy procedure to allow time to have a careful look on withdrawing the colonoscopy)
