Objective To explore the effect of quantitative evaluation strategy-centered regulated care in postoperative care of patients with cardiac cancer

so as to provide a reference for clinical treatment. Methods Eighty-seven patients who underwent cardiac cancer surgery in Huaihe Hospital of Henan University from January 2020 to January 2021 were selected as the study participants. The patients were assigned to the control group（n=43） and the experimental group（n=44） by random number table. Routine postoperative care was used in the control group

and quantitative evaluation strategy-centered regulated care was used in the experimental group. The scores of the General Self-Efficacy Scale（GSES）

Exercise of Self-Care Agency（ESCA）

Hamilton Anxiety Scale（HAMA）

Hamilton Depression Scale（HAMD）

and Quality of Life Questionnaire-Core 30（QOL-C30） for cancer patient were compared between the two groups before and after the intervention. Results Before the intervention

there was no significant difference in GSES and ESCA scores between the two groups（P>0.05）. After the intervention

the GSES and ESCA scores in the two groups were significantly higher than those before the intervention

with the experimental group higher than the control group（P<0.05）. Before the intervention

there was no significant difference in HAMA and HAMD scores between the two groups（P>0.05）. After the intervention

the HAMA and HAMD scores of the two groups were significantly lower than those before the intervention

with the experimental group lower than the control group（P<0.05）. The incidence rate of complications in the experimental group was significantly lower than that in the control group（P<0.05）. Before the intervention

there was no significant difference in QOL-C30 scores between the 2 groups（P>0.05）. After the intervention

the QOL-C30 scores of patients in both groups were significantly lower than those before the intervention

with the experimental group lower than the control group（P<0.05）. Conclusion Quantitative evaluation strategy-centered regulated care can improve the self-efficacy and self-care ability of patients with cardiac cancer after the operation

relieve negative emotions

reduce the occurrence of complications

and improve the quality of life. These benefits hold promise for a wider application of this procedure clinically.
