An acquaintance of my wife has a 4 month old baby. Doctors recommend babies are bottle or formula fed until they are one year old. She doesn't breastfeed and and won't give her baby formula because "it's just corn syrup" (obviously she's not the brightest bulb in the box)
This made me think of countless other times when people believe old wives tales, the internet, their friends or complete strangers over what a qualified physician says. Why? Is it a communication or trust issue? I just don't get it. How can I get my patients to follow my recommendations?
I would say that it is a communication and a trust issue. Going both ways.
Patients come in with a set of ideas that they have gathered from sources both reputable and otherwise, colored by their culture, ability to understand the information, etc.
Our challenge is not just to convince them that we know best and to do as we say. It is to learn to communicate with them on a level that meets them where they are. People do what they are motivated to do, and if we fail to capture their attention and acceptance of the information we provide to them, they will be more motivated to follow advice that does that than anything we tell them.
You describe her as "not the brightest bulb, but although she may be misinformed, she cares about her kid and its nutrition and she is using the best information she has, as she understands it, to make choices that she believes are best for her baby. So, you can't ridicule her for that. You have to make use of that and go from there. Applaud those strengths and show her that you want to be her ally in doing what is best for baby.
Tell her that you agree that giving a baby a lot of corn syrup without other nutrients would be a disaster... but that baby formula is so much more than that. Educate her that it actually contains protein, vitamins, minerals, and healthy fats in amounts that have been proven to provide babies everything that they need to grow and develop normally. Also, it doesn't have ingredients that are known to cause harm to infants, even though they are safe for older children and adults. This gives you a chance to talk about how babies aren't just little adults, that they have particular needs and risks that can be managed.
Instead of squaring off against your patient who is just being obstinate and not blindly following your advice, you are making yourself an ally who appreciates what your patient wants for her baby and who wants to provide the very best information about how to achieve her goals. When your advice is in line with what the patient wants to accomplish, and when they have been helped to see that, you won't be able to stop them from following it.
So, yes, it is communication, and trust, as well as respect, and understanding. Flowing both ways. If you have good relationship building skills, you won't need to ask why patients won't follow your advice. They will, or else you will already know why they decided to make a different choice.
