Some people might expect that a public health program like Nurse-Family Partnership would be equally effective in Canada and the US. But although the program has succeeded in the US, its effectiveness in Canada is currently unknown — due to provinces like BC having better baseline health and social services than most US states. So, the only way to determine how effective NFP will be in Canada is to put it to the test of a randomized controlled trial. This trial is currently underway with first results expected in early 2020.
