Q Fever | A Screening Strategy for Q Fever Among Pregnant Women

Q Fever research study

What is the primary objective of this study?

Q fever in the Netherlands is becoming more common. A Q fever infection is a serious threat to certain risk groups,including pregnant women. Pregnant women are more often than the general population asymptomatic. Studies from France show that an infection with Coxiella burnetii may cause obstetric complications including spontaneous abortion, intrauterine fetal death, intrauterine growth retardation and oligohydramnios. The aim of this study is to assess the effectiveness and cost effectiveness of a multidisciplinary screening program, whereby pregnant women in first line healthcare in high-risk areas for Q fever are screened with a single blood sample during pregnancy. If found positive for Q fever, advise for antibiotic treatment will follow as part of regular healthcare. Treatment is therefore not part of the study protocol. The results of this study will give more insights in the risks of asymptomatic Q fever in pregnancy and the benefits and harms of a screening strategy during pregnancy. This study will be used to give an evidence based advice to the Dutch minister of health on screening for Q fever in pregnancy.
