Objective To develop a screening tool for the risk factors potentially indicating methamphetamine use in pregnant women who are not receiving prenatal care. Method This prospective cohort, Institutional Review Board‐approved study was performed at a university hospital in Thailand between January 2017 and January 2019. A screening tool was developed using data from 125 pregnant women not receiving prenatal care upon their first admission for childbearing at the hospital delivery room. Potential factors obtained from the patient's history, physical examination, and methamphetamine use in pregnancy or had a urine amphetamine test positive were entered into a logistic regression analysis. The discriminative ability of the screening tool was expressed by the area under the receiver operating characteristic curve (AUROC) sensitivity and specificity, while bootstrapping was used for internal validation. Results The screening covered four factors: smoking (odds ratio 7.73, score = 2), drinking (3.81, score = 1), living with a spouse or friend who uses methamphetamine (17.28, score = 3), BP ≥ 130/90 mmHg (2.47, score = 1). The AUROC for the model was 0.87, 95% CI, 0.81–0.93 (SE: 0.03). A total points score ≥3 represented the best cut‐off value, with a sensitivity of 81% and specificity of 82%. Across the bootstrapping, the C‐statistic for the full screening was 0.86, 95% CI, 0.81–0.93 (SE: 0.03). Conclusion A screening tool was developed with an excellent ability to discriminate the risk factors potentially indicating methamphetamine use in pregnant women not receiving prenatal care. Validation in pregnant women receiving prenatal care still needs to be performed.
