This is an article about the controversy surrounding training TBAs. TBAs attend 60% of Guatemalan births and up to 90% among certain groups. However, statistically, training TBAs has not led to the prevention maternal deaths. Since TBAs are often the only choice and are preferred by ill-treated indigenous populations, this subject has hardly been laid to rest.
To me, it seems like CBKs and TBAs are a good fit, since CBK trainings should be simple and straightforward.
