To assess the uptake of the third oral vitamin K dose in general practice.
Infants born between 1 October 1992 and 4 February 1993 in the Rotorua area were identified. This included all infants born at the maternity unit and home births within the Rotorua area. The general practitioner recorded as the preferred primary healthcare provider was contacted and a questionnaire completed.
There were 521 recorded births. Of these 104 were excluded as they were non resident within the Rotorua area. Of those infants residing in Rotorua after birth (417), a further 77 were excluded due to: No general practitioner identified 3; deaths 3; transfers--outcome unknown 18; and intramuscular vitamin K given at birth 53, giving a survey population of 340. Forty general practitioners were identified as the preferred primary health care provider. There was a 100% questionnaire response rate. In the survey population the uptake of the third dose of vitamin K was 90.6%. (308 out of 340).
Further investigation is required to identify those infants not receiving the third oral dose and why. A more specific questionnaire requesting information as to why the third dose was omitted should have been designed. It may be necessary to consider the use of a single intramuscular dose of vitamin K to those breastfed infants who can be considered to have a high probability of not receiving the three oral doses of vitamin K within the first six weeks of life regardless of other risk factors.
评估全科医疗中第三剂口服维生素K的摄取情况。
确定1992年10月1日至1993年2月4日在罗托鲁瓦地区出生的婴儿。这包括在产科病房出生的所有婴儿以及罗托鲁瓦地区的家庭分娩婴儿。联系记录在案的首选初级医疗服务提供者——全科医生，并完成一份调查问卷。
记录的出生人数为521例。其中104例因不住在罗托鲁瓦地区而被排除。在出生后居住在罗托鲁瓦的婴儿（417例）中，另有77例被排除，原因如下：未确定全科医生3例；死亡3例；转出——结果未知18例；出生时已注射维生素K 53例，最终调查人群为340例。确定了40名全科医生为首选初级医疗服务提供者。调查问卷的回复率为100%。在调查人群中，第三剂维生素K的摄取率为90.6%（340例中的308例）。
需要进一步调查以确定那些未接受第三剂口服维生素K的婴儿及其原因。本应设计一份更具体的问卷，询问遗漏第三剂的原因。对于那些无论其他风险因素如何，在出生后头六周内极有可能未接受三剂口服维生素K的母乳喂养婴儿，可能有必要考虑使用单剂肌肉注射维生素K。
