Objective To observe the effect of nursing intervention based on information-motivation-behavioral skill (IMB) model in CT-guided localization of patients with isolated pulmonary nodules (SPN).

Methods A total of 60 patients who planned to undergo CT-guided SPN localization were randomly divided into observation group and controlgroup, with 30 cases in each group. The observation group was given nursing intervention based on IMB model, and the control group was given conventional nursing mode. The cognitive degree of disease, psychological state, compliance, complication rate and nursing satisfaction of the two groups were compared.

Results After intervention, the cognitive scores of disease in the two groups were significantly higher than before intervention, and the observation group was significantly higher than the control group (P < 0.05); the compliance rate of disease cognition in the observation group was 96.67%, which was significantly higher than 76.67% in the control group (P < 0.05). After intervention, the scores of self-rating Anxiety Scale (SAS) and self-rating Depression Scale (SDS) in the two groups were significantly lower than before intervention, and the observation group was significantly lower than the control group (P < 0.05). The compliance of the two groups was significantly higher than before intervention, and the observation group was significantly higher than the control group (P < 0.05). After intervention, the total complication rate of the observation group was significantly lower than that of the control group, and nursing satisfaction was significantly higher than that of the control group (P < 0.05).

Conclusion Nursing intervention based on IMB model can improve the cognitive level, compliance and nursing satisfaction of patients with SPN positioning under CT guidance, relieve anxiety, depression and other states of patients, and has a low incidence of postoperative complications.
