Objective To investigate the current status and correlation of care satisfaction and relational care among obstetrics and gynecology inpatients, and to provide evidence for constructing harmonious nurse-patient relationships. Methods A convenience sampling approach was employed to recruit obstetrics and gynecology inpatients from 148 hospitals across 18 provinces in China between March and November 2025.The general information questionnaire, the Methodist Health Care System Nursing Caring Instrument (NCI) and the Relational Care Scale (patient version) were adopted for investigation. Results The scores of care satisfaction and relational caring were 109.79±15.83 and 70.29±8.04 respectively.Care satisfaction was positively correlated with relational care (P＜0.05).Multiple regression analysis showed that residence, medical payment methods and dimensions of relational care were the main influencing factors of care satisfaction (all P＜0.05). Conclusion Both care satisfaction and relational care are at a good level and closely correlated. Clinically, targeted care needs of patients with different demographic backgrounds should be emphasized, and humanistic care should be implemented throughout nursing practice to improve nursing service quality and patients′ medical experience.
