[Sub-standard factors in primary obstetric care].

Objective: Investigating the frequency and nature of sub-standard care factors in non-complicated pregnancies in primary obstetric care.

Design: Retrospective investigation of medical files.

Method: Data concerning obstetric care in 3 midwifery practices in the Delft area (Pijnacker, Nootdorp, Den Hoorn and Schipluiden), the Netherlands, from 1989-1999 were gathered from the primary National Obstetrics Register. Of the 8362 pregnancy records, 72 were selected at random. Using a checklist containing criteria based on the Obstetrics Indication List, the Cochrane Pregnancy and Childbirth Database, and from an expert panel, the records were analysed for the frequency of occurrence of sub-standard factors in perinatal care.

Results: Of the 72 pregnancy records, only 1 was found to contain no sub-standard factors. On average 1.7 sub-standard factors were seen with a maximum of 7. Most frequently found were: too few check-ups during the first trimester (39%), no testing for proteinuria at the first visit (26%) and no administration of prophylactic vitamin K1 (43%). Less frequently found sub-standard care factors were: no ultrasound despite indication (11%), no referral to secondary care in the event of foetal distress (6%), no consultation with secondary care in the event of hypertension (3%), or in the case of membranes ruptured for more than 24 hours (1%). Frequently the circumstances surrounding the departure from the main checklist criteria were found to justify the action.

Conclusion: Sub-standard care factors were demonstrated in many of the pregnancies investigated. A limited number of these factors gave reason to question whether guidelines for good quality perinatal care are being properly applied.
