Not everyone experience the same, Can quote some examples.
Elderly knock on head, thought it's ok and let it be. After a few days became mentally unwell, disoriented . Went to sengkang hospitial and did scan. DR say blood clot, take med and observe first. Then in-between doctors keep changing a senior consultant say no need do anything, let it heal by itself. During the visit to the eldery, can see he randomly got disoriented, sleep walk and etc. Doctors just brushed it aside say no need do ops.
The elderly's daughter went to mount e, within the week the senior dr say just go for ops, the risk is damn low and it doesnt make sense not to do it. Everything resolved and go home within a week, and follow-up scan in 6 and 12 months later.
Another example. Guy 30+,burpling and stomach unwell for weeks. See doctor,dr give some pills and nothing changed. Went polyclinic again, referral for 4 months later at hospital and eat the same meds. The guy dulan went to go private route, within 2 weeks did colonoscopy and endoscopy. Found some gastritis, gave stronger meds and all is good. This example if the guy suay,could be something more serious, the time taken for scan will take at least 6months. Luckily got private insurance,can do everything within 2 weeks.
Another example, an elderly suddenly felt unwell at the heart went to public A&E. Dr did some scan and ct scan, say no problem discharge tell elderly go home as hospitial very full. Elderly still feel uncomfortable, go mount e did more scan and MRI. Found out , got minor stroke, faster ward and treat her. This example if no private insurance, the elderly most likely will get full blown stroke.
Only the rich get speedy treatment is the truth. If you dont have private insuruance, you won't be able to afford all those scan and ward treatment. The diagnosis part is hard as public resources are limited. Public route is good only if your illness is clear cut, discovered and requires immediate attention.
