<jats:title>Abstract</jats:title><jats:sec><jats:title>Background</jats:title><jats:p>Chemotherapy is potentially harmful to a developing foetus, and there are limited data on the foetal impact of chemoimmunotherapy (CIT). Therefore, determining pregnancy status prior to initiation of CIT should be standard of care.</jats:p></jats:sec><jats:sec><jats:title>Aims</jats:title><jats:p>To determine how many women of childbearing age are tested for pregnancy prior to immunochemotherapy administration.</jats:p></jats:sec><jats:sec><jats:title>Methods</jats:title><jats:p>A retrospective chart review at a large Australian metropolitan cancer referral centre, including 304 women aged 18–51 years with a diagnosis of cancer receiving outpatient‐based CIT between 1 May 2015 and 12 June 2020. We assessed the uptake of pregnancy screening and contraception counselling prior to and during first‐line CIT.</jats:p></jats:sec><jats:sec><jats:title>Results</jats:title><jats:p>Only 17.3% of CIT cycles (<jats:italic>n</jats:italic> = 416) screened patients for pregnancy no more than 90 days prior to administration, and the median time between pregnancy screening and treatment was approximately 3 weeks. One patient with early breast cancer had a spontaneous miscarriage estimated at 3–4 weeks' gestation, and neither the patient nor the treating oncologist was aware of this event. This was also the only patient who had a pregnancy test beyond the first cycle of CIT during their treatment.</jats:p></jats:sec><jats:sec><jats:title>Conclusions</jats:title><jats:p>Our results highlight a concerningly low rate of pregnancy screening in women of childbearing age receiving CIT. The implication of missing a positive pregnancy test in this group of women could result in foetal complications, accidental miscarriage, potential bleeding risks and avoidable psychosocial stress. This highlights the urgent need for guidelines to mandate pregnancy testing in women of childbearing age receiving CIT and evidence‐based implementation tools.</jats:p></jats:sec>
