Patient-reported outcomes were investigated at the time of the patient’s outpatient visit (T1), 1 month after the visit (T2), 3 months after the visit (T3), and 6 months after the visit (T4). Latent class growth modeling was used to determine the number and shape of trajectories, and multinomial logistic regression analysis were used to explore influence factors of each class.Results: COPD patients’ reported outcome trajectories were classified into 3 categories: health low-level group (14.80%), health risk group (54.70%), and good health group (30.50%). Logistic regression analysis showed that gender, BMI, smoking history, number of comorbidities, whether it was their first visit, and lung function classification were influential factors in patients’ reported outcome trajectories (P 3, first diagnosis, and lung function class IV had a higher probability of entering the healthy low-level group.Conclusion: COPD patients have poor self-reported health levels during the first 6 months after the outpatient visit, and there is group heterogeneity in patient-reported outcome trajectories; medical staff should give patients specific nursing interventions based on their current development of COPD, self-reported changes, and other relevant influencing factors.Keywords: chronic obstructive pulmonary disease, patient-reported outcomes, trajectory, latent class growth model
