The practice of clinical pharmacists participating in the management of prophylactic antibiotics during the perioperative period of thoracic surgery / 中国基层医药

ABSTRACT

Objective:To explore the role of clinical pharmacists participating in the management of prophylactic antibiotics during the perioperative period of thoracic surgery, and to evaluate the effects after participating in the practice.Methods:The use of antimicrobials during the perioperative period of thoracic surgery in Wenjiang Hospital of Sichuan Provincial People's Hospital in August 2019 (pre-practice) was retrospectively analyzed. The existing problems were summarized, and the possible causes of the existing problems were analyzed. The improvement measures were jointly developed by clinical pharmacists and physicians. Clinical pharmacists continued to manage the use of antimicrobials by means of medication order reviews, ward rounds for pharmacy service, and medication training. The use of prophylactic antibiotics during the perioperative period of thoracic surgery was compared between August 2019 (pre-practice group) and December 2019 (post-practice group) and the practical effect was evaluated.Results:Clinical pharmacists reviewed perioperative patients' medication orders once a day, ward rounds for pharmacy service twice a week, and medication training once a month. Twenty-two patients were enrolled before practice, and 26 patients were enrolled after practice. There were no significant differences in age, sex, body weight, operative time, type of surgical incision, and preventive use of antibiotics between the two groups (all P > 0.05). In the post-practice group, the appropriate time for preoperative administration was 100.0%, which was significantly higher than 88.2% in the pre-practice group. The reasonable rate of preoperative preventive drug selection was 100.0%, which was significantly higher than 44.4% in the pre-practice group ( χ2 = 17.50, P < 0.001). In the post-practice group, the duration of preventive medication was (1.82 ± 0.59) days, which was significantly shorter than (7.54 ± 3.25) days in the pre-practice group ( t = 11.97, P < 0.001). In the post-practice group, the cost of antibacterial drugs was 316.00(237.00,454.25) yuan, which was significantly lower than 1 136.00(391.81 , 2 184.65) yuan in the pre-practice group ( Z = -2.78, P < 0.05). The defined daily dose of antibiotics among inpatients was 2.67(2.00,3.42), which was significantly lower than 8.88(3.92 , 19.18) in the pre-practice group ( Z = -3.26, P < 0.05). There were no significant differences in the incidence of postoperative pulmonary infection and total length of hospital stay between the two groups (both P > 0.05). Conclusion:Clinical pharmacists participating in the management practice of perioperative prophylactic antibiotics in thoracic surgery can effectively promote the rational application of perioperative antibiotics, markedly improve the reasonable rate of prophylactic drug delivery, shorten the course of prophylactic drugs, reduce the cost of antibiotics, decrease the defined daily dose of antibiotics, without increasing the risk of postoperative pulmonary infection and the total length of hospital stay.
