The Bali Indirect Maternal Mortality Study (BIMMS) was conducted in Bali Province, Indonesia in 1991. The objective of the study was to evaluate the indirect sisterhood method for estimating maternal mortality, using a prospective (direct) community-based survey undertaken from 1980 to 1982 among women of reproductive age (Reproductive Age Mortality Survey, or RAMOS) as a comparison. The BIMMS maternal mortality ratio was 331 per 100,000 live births adjusted for 1982. This ratio is similar to the RAMOS one prior to its adjustment, of 359 per 100,000 live births. The sisterhood method was faster, cheaper, and appears to be as accurate as direct methods.
巴厘岛间接孕产妇死亡率研究（BIMMS）于1991年在印度尼西亚巴厘省开展。该研究的目的是评估用于估算孕产妇死亡率的间接姐妹法，将其与1980年至1982年对育龄妇女进行的前瞻性（直接）社区调查（生殖年龄死亡率调查，即RAMOS）进行比较。BIMMS调整后的孕产妇死亡率为每10万例活产331例。该比率与RAMOS调整前的比率相似，即每10万例活产359例。姐妹法更快、更便宜，而且似乎与直接方法一样准确。
