There seems to be a lot of concern about this - especially women being forced into certain labour positions, or medical choices at the whim of the doctor - but I wonder why we don't do anything about it. As in, for those passionate about this issue (which I must admit I'm kind of on the fence on), why not start a petition to the HA and then contact the press to get some pressure going? It may not work - the HA seems to have its own problems to contend with - but has it even been tried?
I don't know how big of a deal it is to most women in the system in Hong Kong, honestly. It seems that most women are honestly content to do what the doctor instructs them to do without questioning it. It's a very doctor/system-centered system here in HK so the stance is whatever is convenient and most efficient for doctors and the system. Also as the system that most women use is public it's kind of a mentality of "you can't expect too much if you're getting public care." In the private system, often the attitude is, "If you don't like how we do it here you can always go public" so it's a very circular argument.
I think the best challenge that the system can get is for women to simply insist on their rights. These rights don't exist just because they are legislated by the HA. These are basic human rights--such as not being restrained without your consent etc. Educate women on what they can do in labor and then prepare them to do it and see what happens. The doctors in HK are the ones that hold the power to educate but they choose not to. That's how I see it.
It starts with a fundamental difference in worldview when it comes to childbirth. Most doctors are educated that childbirth is risky and an emergency situation so that's how they are trained to deal with childbirth. We know that childbirth in itself is not an emergency situation and often what doctors do can turn it into one (unnecessary inductions, c-sections, vacuum extractions, epidurals etc.). But if doctors are only trained to view all childbirths as an emergency that needs to be dealt with and that takes a change in worldview.
So, basically, midwives should be delivering babies and not doctors in most cases. Because there is also a certain emotional/spiritual/mental/metaphysical element that plays a huge part in childbirth that most doctors aren't in touch with--they are in touch with and trained with the physical/biological/scientific elements of childbirth but mostly don't take into account the other huge elements that affect the outcomes of labor and birth. It takes a certain amount of confidence and mental toughness to go through labor naturally and also it takes letting go. I experienced this first-hand with a first labor that lasted 43 hours--likely because of my fear of letting go and then a labor that lasted 12 (felt like a very short 12 too!) because I learned how to let go. In the same way that I find the HA lacking in general bedside manner--this reflects their disconnection with the emotional/mental/psychological elements of providing physical care and simply put, HK isn't a city or system that slows down for those things.
Ideally, women in HK would have the safe option of having midwives attend their births in their homes or there would be birthing centres established so women could have more choice of their birth experience--it would actually save this city a lot of money because midwife-attended births are statistically less risky and require less interventions--same can be said for birthing center births and many women would be excellent candidates for this type of care in HK (where the obesity factor which causes a lot of the high-risk pregnancy cases in other countries) isn't so large.
So, I don't know if anyone has tried a letter writing campaign in HK but first women have to be convinced that it is actually their right to move about during labor and do what it physiologically and psychologically conducive to labor and that they should be standing up for these rights. Doesn't seem like even on a site like this we have much belief in this notion. Again, very circular. People in HK trust doctors and don't question them. Doctor says "Do it this way." Women don't question it. Study comes out saying "Better to do it this way." Women take study to doctor. Doctor says, "No. Do it this way." Women don't question it. The power lies with the doctors.
