sad to hear about your plight, but really, esp in SG, all healthcare workers are burnt out, even the high paying senior consultants...some points:
(1.) For the nurses, most are doing shift duties. So for example if I am doing PM shift today (start at 2 and end at 9.30) and the next day i am rostered AM (start at 7 finish at 2.30), i virtually do not sleep much, maybe 4 or 5 hours, so imagine i am already tired and grouchy, and sometimes one whole shift of staff are on such schedule, how do you think they will treat the patients and their families?
(2.) Moreover the pay is also low, you compare the expertise needed and the effort put in, may it be for the staff nusrse or the dr, with those working in pen pushing jobs, well its no wonder very few locals are still in this industry (govt will tell you they want you to have affordable healthcare), so with the hiring of more foreigners, the most obvious is, language becomes a huge problem, esp to the older patients. Foreigners, esp the pinoys, like to "kai seow" and despite being in the industry and knowing so many of them, i have never seen one that is genuine compassionate to our local patients....I really do not know why they are working here as nurses when they lack compassion...fuck those who support this hiring of foreign nurses policy, hope one day they become old and their kids chuck them into a nursing home to be taken care by foreigners...
(3.) Patient care nowadays is more about legality, rather than genuine care and compassion. e.g. my sister once had viral fever, temp 39.2, went to ttsh a and e, the M.O there said they will only admit her if her temperature is above 39.5 and her blood tests is positive for dengue...i cannot imagine if I still have to crawl to the hospital if my temp is 39.6...its a very obvious fact, nowadays the DOGS that you mention (M.Os and Regs, both local and foreigners, in fact majority of foreign drs, quite the contrary from the nurses, show better care and compassion to their patients) somehow lack compassion and patience when dealing with patients (unless you are one who threaten to complain and can back it up with a lawyer letter, hospitals are very afraid of this...) which leads to...
(4.) The Dr selection criteria in NUS is still very wrong...not many people at the age of 18 (after JC) can make a decision on a life changing career, study 6 years and go to serve out a 6 year bond. Many become disillusioned by the work load (the senior consultants in my hospital, if they are on call, still have to work 12 days straight once every month, is it really worth their basic of $20K, legal issues, complains and all?) and become DOGS, proud and minimal compassion...and also very poor and insensitive communication skills...also due to the bond amount, children from well to do families are still favoured over the poor ones, academic results being equal...
(5.) is healthcare in SG the worst? I can rest assure you from a quality perspective, we are still miles ahead of the USA and definitely one of the best in the world, however it is just too bad every one is stressed out and only worry about their own ricebowl, hence compassion is lacking, and also the local hospital system has taught all of us to be task orientated rather than be patient focused..its really sad cos somehow, hospitals are really run by idiots (why in the world do you need so many CEOs running a healthgroup is beyond me...)
I'm sure people like LKY has a more positive experiences but even he & his family have chosen to go overseas
