Quantity and quality profiles of antibiotics pre, on, and post surgery in a hospital setting

Antibiotics consumption in neurosurgery versus appendectomy: a call for antibiotic stewardship initiatives

Background and aims

Surgical site infection (SSI) remains a significant global health concern, including in Indonesia. The administration of prophylactic antibiotics plays a pivotal role in the prevention and the reduction in mortality rates associated with SSIs. Prophylactic antibiotic use is recommended in surgical procedures that are at risk of infection, including in clean surgical operations that last more than three hours and clean-contaminated surgeries. The objective of this study was to analyze the quantity of prophylactic antibiotic consumption and to compare the consumption of antibiotics between neurosurgery (clean surgery) and appendectomy (clean-contaminated surgery).

Methods

Data in this observational study were obtained from the medical records of patients who underwent neurosurgery and appendectomy at two hospitals in Surabaya: one private and one public hospital. The quantity of antibiotic consumption will be analyzed descriptively and presented as a defined daily dose (DDD) per 100 bed days.

Results

Research findings revealed a higher quantity of antibiotic consumption in elective neurosurgery, representing 47.43 DDD/100 bed-days, in comparison to 21.26 DDD/100 bed-days and 76.34 DDD/100 bed-days in elective and emergency appendectomy, respectively. The most frequently used antibiotics were broad-spectrum antibiotics, which included cefixime (36.91 DDD/100 bed-days) and ceftriaxone (5.45 DDD/100 bed-days) in elective neurosurgery; and ceftriaxone (14.94 vs 50.86 DDD/100 bed-days) and metronidazole (5.75 vs 19.16 DDD/100 bed-days) in elective and emergency appendectomy, respectively.

Conclusion

The consumption of prophylaxis antibiotics remains a significant concern. In order to develop strategies to prevent bacterial resistance through an antibiotic stewardship program, it is essential to evaluate antibiotic consumption and monitor trends over time.

Predictors of Post-Caesarean Surgical Site Infections at Mubende Regional Referral Hospital, Central Uganda: Prospective Cohort Study (July-September 2023)

Background

Post-caesarean surgical site infections (PCSSIs) significantly impact maternal morbidity, mortality, and healthcare costs in low- and middle-income countries, particularly in sub-Saharan Africa, where preventive measures are often inadequate. Despite this burden, data on PCSSIs in this context are limited. This study aimed to evaluate the incidence and factors associated with PCSSIs at Mubende Regional Referral Hospital.

Methods

This prospective cohort study included 204 women who underwent caesarean sections from July to September 2023. Data was collected and participants were monitored for up to 28 days post-delivery to identify occurrences of surgical site infections (SSIs). Statistical analysis was conducted using STATA, with significance defined as a p-value of < 0.05.

Results

Most participants (63.2%) were aged 18-35 years, with over 67% having a parity of ≤4. Preoperative antibiotics were administered to 77.5% of participants. Most surgeries (64.2%) lasted 1-2 hours, and the overall incidence of surgical site infections (SSIs) was 16.18%. Significant risk factors associated with more than a twofold increase in SSI risk included unstable referral status (aRR = 2.02), obstructed labor (aRR = 2.97), chorioamnionitis (aRR = 2.73), and prolonged premature rupture of membranes (PROM) (aRR = 2.05). Prolonged labor increased SSI risk by 1.37-fold (aRR = 1.37), while receipt of preoperative antibiotics was linked to a reduced SSI risk (aRR = 0.77).

Conclusion

The post-caesarean SSI rate at Mubende Regional Referral Hospital is notably high, with key risk factors including unstable referral status, obstructed labor, prolonged labor, chorioamnionitis, and prolonged premature rupture of membranes (PROM). Administering preoperative antibiotics 30 minutes to 1 hour prior to surgery is linked to a reduced risk of SSI.

Ten-year trends of antibiotic prescribing in surgery departments of two private sector hospitals in Central India: a prospective observational study

BACKGROUND

Inappropriate antibiotic use contributes to the global rise of antibiotic resistance, prominently in low- and middle-income countries, including India. Despite the considerable risk of surgical site infections, there is a lack of antibiotic prescribing guidelines and long-term studies about antibiotic prescribing in surgery departments in India. Therefore, this study aimed to analyse 10 years' antibiotic prescribing trends at surgery departments in two tertiary-care hospitals in Central India.

METHODS

Data was prospectively collected from 2008 to 2017 for surgery inpatients in the teaching (TH-15,016) and the non-teaching hospital (NTH-14,499). Antibiotics were classified based on the World Health Organization (WHO) Access Watch Reserve system and analysed against the diagnoses and adherence to the National List of Essential Medicines India (NLEMI) and the WHO Model List of Essential Medicines (WHOMLEM). Total antibiotic use was calculated by DDD/1000 patient days. Time trends of antibiotic prescribing were analysed by polynomial and linear regressions.

RESULTS

The most common indications for surgery were inguinal hernia (TH-12%) and calculus of the kidney and ureter (NTH-13%). The most prescribed antibiotics were fluoroquinolones (TH-20%) and 3rd generation cephalosporins (NTH-41%), and as antibiotic prophylaxis, norfloxacin (TH-19%) and ceftriaxone (NTH-24%). Access antibiotics were mostly prescribed (57%) in the TH and Watch antibiotics (66%) in the NTH. Culture and susceptibility tests were seldom done (TH-2%; NTH-1%). Adherence to the NLEMI (TH-80%; NTH-69%) was higher than adherence to the WHOMLEM (TH-77%; NTH-66%). Mean DDD/1000 patient days was two times higher in the NTH than in the TH (185 vs 90). Overall antibiotic prescribing significantly increased in the TH (β1 =13.7) until 2012, and in the NTH (β2 =0.96) until 2014, and after that decreased (TH, β2= -0.01; NTH, β3= -0.0005). The proportion of Watch antibiotic use significantly increased in both hospitals (TH, β=0.16; NTH, β=0.96).

CONCLUSION

Total antibiotic use decreased in the last three (NTH) and five years (TH), whereas consumption of Watch antibiotics increased over 10 years in both hospitals. The choice of perioperative antibiotic prophylaxis was often inappropriate and antibiotic prescribing was mostly empirical. The results of this study confirmed the need for antibiotic prescribing guidelines and implementation of antimicrobial stewardship programs.

Sustained Improvement of Appropriateness in Surgical Antimicrobial Prophylaxis with the Application of Quality Control Circle

Purpose

Quality control circle (QCC) has acquired success in many fields in healthcare industry as a process management tool, whereas its efficacy in surgical antimicrobial prophylaxis (SAP) remains unknown. This study aimed to implement QCC interventions to improve the appropriateness of SAP.

Methods

A QCC activity team was established to grasp the current situation of SAP in clean surgery procedure, set target, formulate corresponding countermeasures and implement and review them in stages. The plan-do-check-act (PDCA) method was cyclically applied.

Results

The appropriateness of antibiotic prophylaxis before (January to December 2020) and after (January to December 2021) the implementation of QCC activities were evaluated based on relevant international and Chinese SAP guidelines. The overall SAP appropriateness was significantly improved from 68.72% before QCC to 93.7% post QCC implementation (P<0.01). A significant improvement (P<0.05) was also determined for each category: selection (from 78.82% to 96.06%), duration (from 90.15% to 96.46%), indication (from 94.09% to 97.64%), timing of first dose (from 96.55% to 99.21%), antimicrobial usage (from 96.8% to 99.41%), re-dosing of antimicrobial (from 96.55% to 99.21%).

Conclusion

Implementation of a QCC program can optimize the use of antibiotics and improve the appropriateness of SAP and is of practical importance to their standardization.
