AB - Objective. To estimate the risk of adverse birth outcomes for women who underwent non-obstetric surgery during pregnancy compared with those who did not. Background. Previous research suggests that non-obstetric surgery occurs during 1%-2% of pregnancies. However, there is limited evidence quantifying risks to the mother or pregnancy of such surgery. Methods. We examined maternity admissions using hospital administrative data collected between 1st April 2002 and 31st March 2012 and identified pregnancies where non-obstetric surgery occurred. We used logistic regression models to determine the adjusted relative risk, attributable risk and number needed to harm of non-obstetric surgical procedures for adverse birth outcomes.Results. We identified 6,486,280 pregnancies. In 47,628 of these pregnancies, non-obstetric surgery had occurred. We found that non-obstetric surgery during pregnancy was associated with a higher risk of adverse birth outcomes, although the attributable risk was generally low. We estimated that every 287 surgical operations were associated with one additional stillbirth, every 31 operations associated with one additional preterm delivery, every 39 operations associated with one additional low birth weight baby, every 25 operations associated with one additional caesarean section, and every 50 operations associated with one additional long inpatient stay.Conclusions. Although we have no means of disentangling the effect of the surgery from the effect of the underlying condition, we found that the risk associated with non-obstetric surgery was relatively low, confirming that surgical procedures during pregnancy are generally safe. We believe that our findings improve upon previous research, and are useful reference points for any discussion of risk with prospective patients.
