Objective: To analyze from scientific productions how technology with the insertion of Modified Obstetric Alert Scores (MEOWS) can support the health professional responsible for carrying out the reception and risk classification in obstetrics in maternity hospitals. Method: This is an integrative literature review that selected 20 articles in the MEDLINE, LILACS, SciELO and PUBMED databases, which were analyzed and the inclusion criteria applied: articles available in full, published in Portuguese, English and Spanish, that answered the research question. Results: The selected articles were grouped into thematic categories, 1) Nurse's role in welcoming with Obstetric Risk Classification; 2) Insertion of the Modified Obstetric Warning Scoring System (MEOWS) in the Obstetric Urgency and Emergency Unit; 3) Technology and its contribution to Nursing Care. Final considerations: The technology offers a better guarantee for patient safety, as it allows intervention and quick access to the obstetric care needed in the face of the evidenced risk.
