Chronic pain, pain severity and analgesia use in Australian women of reproductive age

Abstract

BackgroundThe increasing prevalence and adverse outcomes associated with opioid analgesia use in women of reproductive age have become a significant public health issue internationally, with use during pregnancy potentially affecting maternal and infant health outcomes. ObjectiveThis study aims to provide national estimates of chronic pain, pain severity and analgesia use in Australian women of reproductive age by pregnancy status. MethodData were obtained from the Australian Bureau of Statistics 2011–12 National Health Survey (n=20,426). Weighting was applied to sample data to obtain population estimates. For this study data were analysed for pregnant (n=166, N=192,617) and non-pregnant women (n=4710, N=5,256,154) of reproductive age (15–49 years). ResultsChronic or reoccurring pain was reported in 5.1% of pregnant women and 9.7% of non-pregnant women, and 0.7% and 2.6% of pregnant and non-pregnant women reported recent opioid analgesia use respectively. Moderate-to-very severe pain was more common in pregnant than non-pregnant women taking opioid analgesics, and no pain and very mild-to-mild pain in non-pregnant women. ConclusionApproximately 1 in 20 pregnant Australian women have chronic or reoccurring pain. Opioid analgesia was used by around 1% of Australian pregnant women during a two-week period, with use associated with moderate-to-very severe pain. Given that the safety of many analgesic medications in pregnancy remains unknown, pregnant women and health professionals require accurate, up-to-date information on the risks and benefits of analgesic use during pregnancy. Further evidence on the decision-making processes of pregnant women with pain should assist health professionals maximise outcomes for mothers and infants.
