Objective To explore the effect of Joint Commission International（JCI）-based pain management on perioperative pain level

hip function and psychological status in patients underwent total hip arthroplasty. Methods A total of 104 patients receiving total hip arthroplasty admitted to a hospital in Nanyang City from January 2015 to January 2018 were selected as subjects

who were assigned to a control group and an observation group via the random number table method

with 52 cases in each group. Patients in the control group received conventional nursing interventions

while patients in the observation group received pain management interventions based on JCI standards

and patients in the 2 groups received continuous interventions until discharge. The preoperative and postoperative levels of interleukin-6（IL-6）

substance P（SP）

and Numerical Rating Scale（NRS） scores at 6 h

12 h

24 h

and 48 h were compared between the two groups. The anxiety and depression status [Hamilton Anxiety Scale（HAMA）

Hamilton Depression Scale（HAMD）] at 48 h before and after the intervention were compared between the two groups. The hip function of patients in the two groups at 3 months

6 months

9 months and 12 months after discharge were compared to that before interventions

and the incidence of adverse reactions during the intervention were compared between the 2 groups.Results The IL-6

SP levels and NRS scores of patients in both groups at 6 h

12 h and 24 h after surgery were higher than those before surgery

and the differences were statistically significant（P<0.05）.The IL-6

SP levels and NRS scores of patients at 6 h

12 h and 24 h after surgery in the observation group were lower than those in the control group

and the differences were statistically significant（P<0.05）.The HAMA and HAMD scores of patients at 48 h after surgery in both groups were lower than those before surgery

with scores in the observation group lower than those in the control group and the differences were statistically significant（P<0.05）.The Harris hip function scores of patients in both groups were higher at 6

9 and 12 months after surgery than those at 3 months after surgery

with scores in the observation group higher than those in the control group

and the differences were statistically significant（P<0.05）.The incidence of adverse reactions during nursing was 11.54% in the observation group

which was lower than that in the control group（28.85%）

and the difference was statistically significant（P<0.05）.Conclusion The pain management based on JCI standards can significantly reduce the perioperative IL-6 and SP levels in patients underwent total hip arthroplasty

decrease the degree of postoperative pain

alleviate postoperative anxiety and depression

and promote the recovery of postoperative hip function.These advantages justify a wider application of this model clinically.
