Objective:To explore the current situation of unmet needs and family environment among gynecology malignant tumor patients and to explore the correlations between them.Methods:From March 2018 to March 2019, this study selected 222 gynecology malignant tumor patients at three Class Ⅲ Grade A hospitals in Hainan Province with the cross-sectional investigation as subjects by convenience sampling. All patients were investigated with the General Information Scale, the Chinese version of Short-Form Survivor Unmet Needs Survey (SF-SUNS) and the Chinese version of Family Environment Scale (FES-CV) . A total of 222 questionnaires were sent out and 216 valid questionnaires were collected with 97.30% for the recovery rate.Results:Among 216 gynecology malignant tumor patients, the total scores of the Chinese version of SF-SUNS and the FES-CV were (73.79±13.82) and (49.12±8.14) respectively.Single factor analysis showed that there were statistical differences in the scores of the Chinese version of SF-SUNS among gynecology malignant tumor patients with different ages, family monthly incomes, education levels and clinical stages of International Federation of Gynecology and Obstetrics. Correlation analysis showed that the total score of FES-CV and scores of the cohesion, expressiveness, independence, knowledge, entertaining and organization dimension were negatively correlated with the dimensions of the Chinese version of SF-SUNS with statistical differences ( P<0.05) . The conflict dimension was positively correlated with the Chinese version of SF-SUNS with statistical differences ( P<0.05) . Hierarchical regression analysis showed that the main influencing factor of unmet needs of gynecology malignant tumor patients was family environment after controlling demographic variables. Conclusions:Unmet needs of gynecology malignant tumor patients are in the intermediate level. Family environment has close correlation with the unmet needs of gynecology malignant tumor patients. Medical staff and their family members should meet needs of patients by improving the family environment so as to improve their quality of life.
