Preterm infants often receive their diphtheria-tetanus-pertussis (DTP) immunizations on a delayed schedule or in reduced dosage. Since primary care physicians (PCPs) immunize many preterm infants, the purpose of this study was to describe PCPs' knowledge about the use of DTP immunizations in preterm infants. Among the 479 PCPs who completed the questionnaire, 84% of pediatricians and 60% of family physicians correctly identified chronologic age as a criterion for initiating DTP immunizations in preterm infants. However, nearly 45% of PCPs linked this with other criteria such as a minimum weight requirement. Family physicians' answers differed from the recommendations more often than pediatricians' answers. The answers of pediatricians and family physicians who completed residency greater than 20 years ago differed from the recommendations more often than those who completed training less than or equal to 20 years ago. The answers of PCPs with fewer than five preterm infants in their practices differed from the recommendations more frequently than the answers of those with five or more preterm infants in their practices. Educational interventions are needed to bring PCPs' knowledge and practices into compliance with the American Academy of Pediatrics recommendations concerning DTP immunizations for preterm infants.
早产儿通常会延迟接种白喉-破伤风-百日咳（DTP）疫苗或减少接种剂量。由于初级保健医生（PCP）为许多早产儿接种疫苗，本研究的目的是描述PCP对早产儿使用DTP疫苗的了解情况。在完成问卷的479名PCP中，84%的儿科医生和60%的家庭医生正确地将实际年龄确定为开始对早产儿接种DTP疫苗的标准。然而，近45%的PCP将其与其他标准（如最低体重要求）联系起来。家庭医生的回答比儿科医生的回答更常与建议不同。20多年前完成住院医师培训的儿科医生和家庭医生的回答比20年或更短时间内完成培训的医生更常与建议不同。实践中接触不到五名以下早产儿的PCP的回答比实践中接触五名或更多早产儿的PCP的回答更频繁地与建议不同。需要进行教育干预，以使PCP的知识和实践符合美国儿科学会关于早产儿DTP疫苗接种的建议。
