In some instances, this merely necessitates "code-switching" -- the use of different words and speaking patters in different cultural settings (e.g. The difference between conversation at a business meeting and a baseball game, although with intercultural issues the impact of code-switching becomes far more profound). On a less esoteric level, however, there is the simple issue of language barriers in providing equal multicultural care. Evidence shows that simply increasing he availability of multilingual care -- especially in populations with a large number of non-English speakers -- greatly increases the quality of healthcare and overall health of immigrant populations (Ngo-Metzger et al., 2003). This suggests one of the main ways that the healthcare industry can combat these barriers -- simply educating more providers in cultural differences, and actively recruiting new students and practitioners from among different cultures and across linguistic lines will greatly improve the availability and accessibility...

At the same time, such measures would help to integrate these other cultures, making them aware of the healthcare available to them and hopefully instilling trust of Western medical techniques in them.
Surmounting the cultural barriers to healthcare that exist can only be accomplished by programs that educate and promote understanding among providers and patients alike. The healthcare industry needs to become more aware of the various cultural demands made on it, while at the same time promoting their own ideas and qualifications among multicultural populations to promote their understanding.
