Compliance of antibiotics used for surgical site infection prophylaxis among patients undergoing surgery in a Congolese teaching hospital

Mitigating inequitable access to appropriate antibiotics in low- and middle-income countries

Access to effective medicines (e.g. antibiotics) is a fundamental human right. However, in contrast to high-income countries (HICs), many low- and middle-income countries (LMICs) lack appropriate and effective antibiotics. This is a paradox, and an inequitable scenario, as LMICs can have significantly higher burdens of infectious diseases than HICs and especially require appropriate antibiotics. Inequitable access to appropriate antibiotics results in patients being treated with substandard antibiotics, treatment failure, the emergence of antimicrobial resistance (AMR) and, inevitably, morbidity and mortality. Factors that hinder access to appropriate antibiotics in LMICs include: poor political will, weak health systems, complex bureaucratic protocols, poor implementation of National Action Plans on AMR, inadequate expertise in regulatory science, unfavourable macroeconomic policies and a poor investment climate. Clearly, multisectoral, collaborative approaches are required to effectively mitigate inequitable access to appropriate antibiotics in LMICs. Also, efforts (such as the African Medicines Regulatory Harmonization Initiative and the African Medicines Agency) to streamline bureaucratic processes and improve the registration and entry of appropriate antibiotics into LMICs are required. This review discusses factors responsible for inequitable access to appropriate antibiotics in LMICs, and makes recommendations to mitigate the problem. With rising rates of AMR, a dwindling antibiotic pipeline, and the dangers of a post-antibiotic era, it is clear that the time to act is now, as inequitable access to appropriate antibiotics in LMICs reduces the quality of healthcare, and threatens the achievement of Universal Health Coverage and, ultimately, the Sustainable Development Goals.

Antibiotic prophylaxis practice in gastrointestinal surgery in five hospitals in southern Benin

Background

Benin's healthcare system is characterized by a lack of local guidelines for surgical antibiotic prophylaxis (SAP), which is essential to prevent surgical site infection.

Aim

To audit compliance for SAP practices in gastrointestinal surgery.

Methods

Data were prospectively collected from gastrointestinal surgery departments in five hospitals. Over a four month period, SAP was assessed using five conventional criteria (indication, choice of antibiotic, dosage, timing, and duration of administration) among patients admitted for Altemeier class 1 or 2 procedures. Three guidelines were used as reference: World Health Organization (WHO), American Society of Health-System Pharmacists (ASHP)and French Society of Anaesthesia and Intensive Care Medicine (SFAR).

Findings

Of 68 surgical interventions, overall compliance with WHO, ASHP, and SFAR was observed in zero (0.0%), one case (1.5%) and two cases (2.9%), respectively. Compliance with indication varied according to the guidelines: 65 (95.6%) were compliant with WHO and ASHP and 47 cases (69.11%) with SFAR. Among compliant cases, the antibiotics administered were rarely selected according to guidelines: WHO, 2 (2.9%) and ASHP, 2 (2.9%), and SFAR, 3 (4.4%). Drug dosage compliance varied from 20 (29.4%) (SFAR) to 49 (72.0%) (ASHP). Timings were respected in 47 (69.1%; WHO), 45 (66.2%; ASHP) and 9 cases (13.2%; SFAR). The number of cases compliant with antibiotic prophylaxis duration were 13 (19.1%; WHO), 17 (25.0%; ASHP) and 16 (23.5%; SFAR).

Conclusion

The SAP compliance rate in gastrointestinal surgery based on the five conventional criteria was very low. SAP guidelines must be implemented appropriately for local bacteriological epidemiology.

Assessment of antimicrobial prescribing patterns, guidelines compliance, and appropriateness of antimicrobial prescribing in surgical-practice units: point prevalence survey in Malaysian teaching hospitals

Objectives: This study sought to investigate the quality of antimicrobial prescribing among adult surgical inpatients besides exploring the determinants of non-compliance and inappropriate prescribing to inform stewardship activities. Methods: A cross-sectional point prevalence study employing Hospital National Antimicrobial Prescribing Survey (Hospital NAPS) was conducted in April 2019 at two teaching hospitals in Malaysia. Results: Among 566 surgical inpatients, 44.2% were receiving at least one antimicrobial, for a total of 339 prescriptions. Antimicrobials belonging to the World Health Organization's Watch group were observed in 57.8% of cases. Both hospitals exhibited similar types of antimicrobial treatments prescribed and administration routes. A significant difference in antimicrobial choice was observed between hospitals (p < 0.001). Hospital with electronic prescribing demonstrated better documentation practice (p < 0.001). Guidelines compliance, 32.8% (p = 0.952) and appropriateness, 55.2% (p = 0.561) did not significantly differ. The major contributors of inappropriateness were incorrect duration, (15%) and unnecessary broad-spectrum coverage, (15.6%). Non-compliance and inappropriate prescribing were found to be 2 to 4 times significantly higher with antimicrobial prophylaxis prescription compared to empirical therapy. Conclusion: Antimicrobial stewardship efforts to improve appropriate surgical prescribing are essential. These initiatives should prioritize surgical prophylaxis prescribing, focusing on reducing unnecessarily prolonged use and broad-spectrum antimicrobials, raising awareness among prescribers and promoting proper documentation.

Prevalence, risk factors, and antimicrobial resistance of endemic healthcare-associated infections in Africa: a systematic review and meta-analysis

BACKGROUND

Healthcare-associated infections (HCAI) place a significant burden on healthcare systems globally. This systematic review and meta-analysis aimed to investigate the prevalence, risk factors, and aetiologic agents of endemic HCAI in Africa.

METHODS

MEDLINE/PubMed, CINAHL, and Global Health databases (EBSCOhost interface) were searched for studies published in English and French describing HCAI in Africa from 2010 to 2022. We extracted data on prevalence of HCAI, risk factors, aetiologic agents, and associated antimicrobial resistance patterns. We used random-effects models to estimate parameter values with 95% confidence intervals for risk factors associated with HCAI. This study was registered in PROSPERO (CRD42022374559) and followed PRISMA 2020 guidelines.

RESULTS

Of 2541 records screened, 92 were included, comprising data from 81,968 patients. Prevalence of HCAI varied between 1.6 and 90.2% with a median of 15% across studies. Heterogeneity (I2) varied from 93 to 99%. Contaminated wound (OR: 1.75, 95% CI: 1.31-2.19), long hospital stay (OR: 1.39, 95% CI: 0.92-1.80), urinary catheter (OR: 1.57, 95% CI: 0.35-2.78), intubation and ventilation (OR: 1.53, 95% CI: 0.85-2.22), vascular catheters (OR: 1.49, 95% CI: 0.52-2.45) were among risk factors associated with HCAI. Bacteria reported from included studies comprised 6463 isolates, with E. coli (18.3%, n = 1182), S. aureus (17.3%, n = 1118), Klebsiella spp. (17.2%, n = 1115), Pseudomonas spp. (10.3%, n = 671), and Acinetobacter spp. (6.8%, n = 438) being most common. Resistance to multiple antibiotics was common; 70.3% (IQR: 50-100) of Enterobacterales were 3rd -generation cephalosporin resistant, 70.5% (IQR: 58.8-80.3) of S. aureus were methicillin resistant and 55% (IQR: 27.3-81.3) Pseudomonas spp. were resistant to all agents tested.

CONCLUSIONS

HCAI is a greater problem in Africa than other regions, however, there remains a paucity of data to guide local action. There is a clear need to develop and validate sustainable HCAI definitions in Africa to support the implementation of routine HCAI surveillance and inform implementation of context appropriate infection prevention and control strategies.

Antibiotic Utilization Patterns for Different Wound Types among Surgical Patients: Findings and Implications

Antimicrobial prophylaxis is effective in reducing the rate of surgical site infections (SSIs) post-operatively. However, there are concerns with the extent of prophylaxis post-operatively, especially in low- and middle-income countries (LMICs). This increases antimicrobial resistance (AMR), which is a key issue in Pakistan. Consequently, we conducted an observational cross-sectional study on 583 patients undergoing surgery at a leading teaching hospital in Pakistan with respect to the choice, time and duration of antimicrobials to prevent SSIs. The identified variables included post-operative prophylactic antimicrobials given to all patients for all surgical procedures. In addition, cephalosporins were frequently used for all surgical procedures, and among these, the use of third-generation cephalosporins was common. The duration of post-operative prophylaxis was 3-4 days, appreciably longer than the suggestions of the guidelines, with most patients prescribed antimicrobials until discharge. The inappropriate choice of antimicrobials combined with prolonged post-operative antibiotic administration need to be addressed. This includes appropriate interventions, such as antimicrobial stewardship programs, which have been successful in other LMICs to improve antibiotic utilization associated with SSIs and to reduce AMR.

Evaluation of the practice of surgical antibiotic prophylaxis in a Zonal Referral Hospital in Mbujimayi, Democratic Republic of the Congo (DRC)

BACKGROUND

Surgical Antibiotic Prophylaxis (SAP) is helpful in preventing patients from developing Surgical Site Infections (SSI). In Mbujimayi, the documentation on the practice of SAP is outdated and inadequate. The last study was conducted more than 5 years ago. This study aims at assessing the compliance of the practice of antibiotic prophylaxis in the surgical and obstetrics-gynecology departments of the Bonzola Zonal Referral Hospital (BZRH) compared to the international standards.

METHODS

A prospective observational study was conducted from March 2020 to March 2021 involving 324 surgical patients who received antibiotic prophylaxis. Interventions were assessed as "compliant" if all the variables individually complied with the criteria for antibiotic prophylaxis use.

RESULTS

Three hundred and twenty-four patients were enrolled in this study. Compliance was found to be 87.35% for the indication for administration; 0.31% for the choice of the molecule; 3.65% for the time of the first administration; none for the duration of antibiotic prophylaxis. Therefore, the overall compliance was nil. This study shows a significant gap when the current practice in Mbujimayi town is compared to the recommendations of international societies.

CONCLUSION

SAP is often indicated in accordance with international recommendations in Mbujimayi. However, the choice of the molecule, the dosage, the time of first administration and the duration of SAP deviate from them. Thus, the compliance of SAP is nil.

Ongoing Efforts to Improve Antimicrobial Utilization in Hospitals among African Countries and Implications for the Future

There are serious concerns with rising antimicrobial resistance (AMR) across countries increasing morbidity, mortality and costs. These concerns have resulted in a plethora of initiatives globally and nationally including national action plans (NAPs) to reduce AMR. Africa is no exception, especially with the highest rates of AMR globally. Key activities in NAPs include gaining a greater understanding of current antimicrobial utilization patterns through point prevalence surveys (PPS) and subsequently instigating antimicrobial stewardship programs (ASPs). Consequently, there is a need to comprehensively document current utilization patterns among hospitals across Africa coupled with ASP studies. In total, 33 PPS studies ranging from single up to 18 hospitals were documented from a narrative review with typically over 50% of in-patients prescribed antimicrobials, up to 97.6% in Nigeria. The penicillins, ceftriaxone and metronidazole, were the most prescribed antibiotics. Appreciable extended prescribing of antibiotics up to 6 days or more post-operatively was seen across Africa to prevent surgical site infections. At least 19 ASPs have been instigated across Africa in recent years to improve future prescribing utilizing a range of prescribing indicators. The various findings resulted in a range of suggested activities that key stakeholders, including governments and healthcare professionals, should undertake in the short, medium and long term to improve future antimicrobial prescribing and reduce AMR across Africa.

Individualized surgical antibiotic prophylaxis – why, when, and how?

"Surgical site infections (SSI) greatly concern clinicians, as they are associated with significant morbidity and mortality, prolonged hospitalization, and costs. Antibiotic prophylaxis plays a pivotal role among the procedures that are usually employed for the prevention of surgical-related infections. This narrative review aims to cover some of the particular situations when the clinician might consider individualizing antibiotic prophylaxis for a patient. With the rising incidence of multi-drug resistant bacteria carriage among not only hospitalized or institutionalized patients but also patients from the community, there might be a tendency to use extended-spectrum antibiotics for longer periods for surgical infection prevention. However, the inappropriate use of antibiotics increases the selection pressure, thus favoring the spreading of resistant bacteria. Moreover, specific patient characteristics or pathologies might need to be considered to customize the type, dose, or length of administration of an antibiotic as surgical prophylaxis. Using prosthetic material or prolonged surgeries with large fluid shifts are other situations when individualized antibiotic prophylaxis might be thought of. Keeping in mind that it is of utmost importance that everyone adheres to the current guidelines for surgical antibiotic prophylaxis, customization of local protocols according to well-thought-out strategies might prove beneficial in SSI prevention."

Surgical antimicrobial prophylaxis among surgical patients: results from a retrospective observational study at a public hospital in Liberia

BACKGROUND

Surgical antibiotic prophylaxis (SAP) is one of the most effective measures to prevent surgical site infections (SSIs). According to WHO SAP guidelines, SAP requires appropriate indication for administration and delivery of the antimicrobial agent to the operative site through intravenous administration within 60-120 min before the initial surgical incision is made. In Liberia, it is unknown how surgeons practice and there has been anecdotal observation of antibiotic overuse.

OBJECTIVE

To elucidate baseline SAP compliance, particularly appropriate SAP use based on wound class and time of antibiotic administration.

METHODS

An observational, cross-sectional study was conducted from November to December 2017. One-day training was provided on SAP/SSI to 24 health workers by the Ministry of Health and WHO. Following this training, surgical cases (general surgery and obstetrics and gynaecology (OB/GYN) underwent chart review with focus on time of SAP administration and appropriate SAP based on Centers for Disease Control and Prevention (CDC) wound classification.

RESULTS

A total of 143 charts were reviewed. Twenty-nine (20.3%) cases showed appropriate prophylaxis through administrations of antibiotics 120 min before surgical incision, resulting in SAP compliance. One hundred and fourteen cases (79.7%) showed SAP noncompliance with timing of antibiotic administration. Of the OB/Gyn cases, 109 wounds were classified as Class I (clean) and one wound was classified as Class III (contaminated). For General Surgical cases, 32 wounds were classified as Class I and one as Class III. Of the 109 Class I OB/Gyn surgeries, 24 (22%) were appropriately given antibiotics based on the CDC wound guidelines while 78% were non-compliant with recommendations. Of the 32 Class I General surgery cases, 4 (12.5%) were compliant with antibiotics guidelines while 28 (87.5%) were not.

CONCLUSION

Compliance with SAP is low. More studies need to be done to explore the contributing factors to this. Implementing mechanisms to achieve proper use of SAP is needed.

Healthcare-associated infections and antimicrobial use in surgical wards of a large urban central hospital in Blantyre, Malawi: a point prevalence survey

Background

There are limited data on healthcare-associated infections (HAI) from African countries like Malawi.

Aim

We undertook a point prevalence survey of HAI and antimicrobial use in the surgery department of Queen Elizabeth Central Hospital (QECH) in Malawi and ascertained the associated risk factors for HAI.

Methods

A cross-sectional point prevalence survey (PPS) was carried out in the surgery department of QECH. The European Centre for Disease Prevention and Control PPS protocol version 5.3 was adapted to our setting and used as a data collection tool.

Findings

105 patients were included in the analysis; median age was 34 (IQR: 24-47) years and 55.2% patients were male. Point prevalence of HAI was 11.4% (n=12/105) (95% CI: 6.0%-19.1%), including four surgical site infections, four urinary tract infections, three bloodstream infections and one bone/joint infection. We identified the following risk factors for HAI; length-of-stay between 8 and 14 days (OR=14.4, 95% CI: 1.65-124.7, p=0.0143), presence of indwelling urinary catheter (OR=8.3, 95% CI: 2.24-30.70, p=0.003) and history of surgery in the past 30 days (OR=5.11, 95% CI: 1.46-17.83, p=0.011). 29/105 patients (27.6%) were prescribed antimicrobials, most commonly the 3rd-generation cephalosporin, ceftriaxone (n=15).

Conclusion

The prevalence rates of HAI and antimicrobial use in surgery wards at QECH are relatively high. Hospital infection prevention and control measures need to be strengthened to reduce the burden of HAI at QECH.
