In an attempt to evaluate the contributory factors to the high frequency of referred cases in obstructed labour at the State's referral hospital, a questionnaire-based survey of 396 maternity care-providers from 66 randomly selected peripheral delivery units in Ogun State, Nigeria was conducted over a 2-month period, to evaluate their knowledge and use of the partograph. The majority of the personnel were nurses/midwives (45.5%) and community health extension workers (CHEW) (42.7%). Of the 216 personnel (54.5%) who were aware of the partograph, 36 (16.7%), 119 (55.5%) and 61 (28.2%) demonstrated poor, fair and good levels of knowledge, respectively. No junior CHEW had a satisfactory knowledge of the partograph. Only 39 (9.8%) of all the personnel routinely employed the partograph for labour management and almost half of these individuals had a poor level of knowledge. Efforts to limit the frequency of referred cases of established obstructed labour to the State's referral hospital should include training of care-providers at the peripheral delivery units, especially junior personnel in the effective use of the partograph, in addition to employing quality assurance measures to check inappropriate use.
