Construction and effect evaluation of pain control quality system in patients with total knee arthroplasty

Objective To establish, implement and evaluate the pain control quality system for patients with total knee arthroplasty (TKA) . Methods Through literature search and interviews with medical staff and retrospective reviews of TKA cases in orthopedic wards, the problems in pain control of TKA patients during perioperative period were analyzed. According to the evidence-based practice guideline and the existing problems in pain nursing practice, the pain control quality system was constructed. From January to November 2018, 75 TKA patients in Orthopedic Department, Ningbo First Hospital were selected as the research objects and randomly divided into the control group (n=35) and the intervention group (n=40) . The control group received the routine pain nursing mode, and the intervention group was managed by the pain control quality system. The static and dynamic VAS scores on the 1st, 3rd and 7th day after TKA, the incidence of analgesia-related complications and the quality of pain nursing were compared between the two groups. Results There were significant statistical differences in static and dynamic VAS scores of knee joint between the two groups on the 1st, 3rd and 7th day after operation (P 0.05) . The total score of TKA perioperative pain nursing quality in the intervention group was 84 (80, 85) , while that of the control group was 56 (53, 58) . The difference between the two groups was statistically significant (P<0.01) . Conclusions The construction of pain control quality system can effectively improve the level of perioperative pain management of TKA, the quality of pain nursing care, and improve the perioperative pain of TKA patients.
