Rapid Assessment of the Potential Paucity and Price Increases for Suggested Medicines and Protection Equipment for COVID-19 Across Developing Countries With a Particular Focus on Africa and the Implications

Background: Countries across Africa and Asia have introduced a variety of measures to prevent and treat COVID-19 with medicines and personal protective equipment (PPE). However, there has been considerable controversy surrounding some treatments including hydroxychloroquine where the initial hype and misinformation led to shortages, price rises and suicides. Price rises and shortages were also seen for PPE. Such activities can have catastrophic consequences especially in countries with high co-payment levels. Consequently, there is a need to investigate this further. Objective: Assess changes in utilisation, prices, and shortages of pertinent medicines and PPE among African and Asian countries since the start of pandemic. Our approach: Data gathering among community pharmacists to assess changes in patterns from the beginning of March until principally the end of May 2020. In addition, suggestions on ways to reduce misinformation. Results: One hundred and thirty one pharmacists took part building on the earlier studies across Asia. There were increases in the utilisation of principally antimalarials (hydroxychloroquine) and antibiotics (azithromycin) especially in Nigeria and Ghana. There were limited changes in Namibia and Vietnam reflecting current initiatives to reduce inappropriate prescribing and dispensing of antimicrobials. Encouragingly, there was increased use of vitamins/immune boosters and PPE across the countries where documented. In addition, generally limited change in the utilisation of herbal medicines. However, shortages have resulted in appreciable price increases in some countries although moderated in others through government initiatives. Suggestions in Namibia going forward included better planning and educating patients. Conclusion: Encouraging to see increases in the utilisation of vitamins/immune boosters and PPE. However, concerns with increased utilisation of antimicrobials needs addressing alongside misinformation, unintended consequences from the pandemic and any appreciable price rises. Community pharmacists and patient organisations can play key roles in providing evidence-based advice, helping moderate prices through improved stock management, and helping address unintended consequences of the pandemic.

Impact of the COVID-19 pandemic on community antibiotic prescribing in Scotland

Background

Following concerns about increased antibiotic use during the COVID-19 pandemic, trends in community antibiotic prescriptions in Scotland were evaluated.

Methods

The primary care prescription electronic messaging system used in GP practices with NHS contracts provided near real-time data analysis of national data. The main outcome measures were the weekly number of prescriptions for antibiotics generated by prescribers in GP practices in 2020 compared with 2019.

Results

At end of Week 12 2020 (22 March), after a sharp increase, the number of prescriptions commonly used for respiratory infections was 44% higher than the corresponding week in 2019. The number of prescriptions for respiratory antibiotics reduced through April and May 2020, with 34% fewer prescriptions issued by end of Week 22 (31 May) than in the corresponding week in 2019. Reductions were pronounced in all age groups but particularly apparent for prescriptions for children aged 0–4 years. These data were compared with weekly prescriptions for a selection of non-respiratory antibiotics and no difference was seen between 2020 and 2019.

Conclusions

Trends in antibiotic prescription data show that after an initial surge, and following ‘lockdown’ in Scotland, the total number of prescriptions for antibiotics commonly used for respiratory infections fell. We believe this is the first published national evaluation of the impact of COVID-19 on community use of antibiotics. Further analysis of national data is planned to provide a greater understanding of the reasons behind these trends.

Survey of antibiotic and antifungal prescribing in patients with suspected and confirmed COVID-19 in Scottish hospitals

BACKGROUND

Concern regarding bacterial co-infection complicating SARS-CoV-2 has created a challenge for antimicrobial stewardship. Following introduction of national antibiotic recommendations for suspected bacterial respiratory tract infection complicating COVID-19, a point prevalence survey of prescribing was conducted across acute hospitals in Scotland.

METHODS

Patients in designated COVID-19 units were included and demographic, clinical and antimicrobial data were collected from 15 hospitals on a single day between 20th and 30th April 2020. Comparisons were made between SARS-CoV-2 positive and negative patients and patients on non-critical care and critical care units. Factors associated with antibiotic prescribing in SARS-CoV-2 positive patients were examined using Univariable and multivariable regression analyses.

FINDINGS

There were 820 patients were included, 64.8% were SARS-CoV-2 positive and 14.9% were managed in critical care, and 22.1% of SARS-CoV-2 infections were considered probable or definite nosocomial infections. On the survey day, antibiotic prevalence was 45.0% and 73.9% were prescribed for suspected respiratory tract infection. Amoxicillin, doxycycline and co-amoxiclav accounted for over half of all antibiotics in non-critical care wards and meropenem, piperacillin-tazobactam and co-amoxiclav accounted for approximately half prescribed in critical care. Of all SARS-CoV-2 patients, 38.3% were prescribed antibiotics. In a multivariable logistic regression analysis, COPD/chronic lung disease and CRP ≥ 100 mg/l were associated with higher odds and probable or confirmed nosocomial COVID-19, diabetes and management on an elderly care ward had lower odds of an antibiotic prescription. Systemic antifungals were prescribed in 9.8% of critical care patients and commenced a median of 18 days after critical care admission.

INTERPRETATION

A relatively low prevalence of antibiotic prescribing in SARS-CoV-2 hospitalised patients and low proportion of broad spectrum antibiotics in non-critical care settings was observed potentially reflecting national antimicrobial stewardship initiatives. Broad spectrum antibiotic and antifungal prescribing in critical care units was observed indicating the importance of infection prevention and control and stewardship initiatives in this setting.

FUNDING

The Scottish Antibiotic Prescribing Group is funded by Scottish Government.

Supporting antimicrobial stewardship in Ghana: evaluation of the impact of training on knowledge and attitudes of healthcare professionals in two hospitals

BACKGROUND

A Commonwealth Partnership for Antimicrobial Stewardship was created between the Scottish Antimicrobial Prescribing Group (SAPG), Ghana Police Hospital and Keta Municipal Hospital. During a scoping visit, requirements for implementing antimicrobial stewardship (AMS), areas for improvement and training needs were identified.

METHODS

A multidisciplinary team from SAPG and health psychologists from The Change Exchange developed and delivered multi-professional evidence-based teaching incorporating behavioural science, supported by partner pharmacists in each hospital. Four sessions were delivered over 2 days to 60 participants across both sites. Before and after the sessions, participants were asked to complete a knowledge quiz and a behaviours survey. Results were analysed using t-tests.

RESULTS

Comparison of the participants' pre- and post-test quiz scores (Keta Municipal Hospital 9.4 and 10.9, Ghana Police Hospital 9.2 and 11.1, respectively) demonstrated statistically significant improvement in knowledge of antimicrobial resistance and appropriate use of antibiotics. Comparison of survey responses before and after the education sessions indicated that the education had a positive impact on participants' attitudes towards the issue of antimicrobial resistance, their role in AMS and confidence in using the Ghana Standard Treatment Guidelines. Participants were also more likely to question colleagues about compliance with guidelines. Forty-eight participants (80%) completed a training evaluation and all responded positively.

CONCLUSIONS

The education sessions appeared to be successful in improving knowledge and behaviours of hospital staff. Cascade of an abbreviated version of the training by partner pharmacists and AMS teams in Ghana will ensure that all staff have the opportunity to develop skills and knowledge to support AMS.

Antimicrobial use at the end of life: a scoping review

OBJECTIVE

To examine antibiotic use in patients approaching end of life, in terms of frequency of prescription, aim of treatment, beneficial and adverse effects and contribution to the development of antimicrobial resistance.

DESIGN

Scoping review DATA SOURCES: An information scientist searched Ovid MEDLINE, Ovid EMBASE, The Cochrane library, PubMed Clinical Queries, NHS Evidence, Epistemonikos, SIGN, NICE, Google Scholar from inception to February 2019 for any study design including, but not limited to, randomised clinical trials, prospective interventional or observational studies, retrospective studies and qualitative studies. The search of Ovid MEDLINE was updated on the 10 June 2020.

STUDY SELECTION

Studies reporting antibiotic use in patients approaching end of life in any setting and clinicians' attitudes and behaviour in relation to antibiotic prescribing in this population DATA EXTRACTION: Two reviewers screened studies for eligibility; two reviewers extracted data from included studies. Data were analysed to describe antibiotic prescribing patterns across different patient populations, the benefits and adverse effects (for individual patients and wider society), the rationale for decision making and clinicians behaviours and attitudes to treatment with antibiotics in this patient group.

RESULTS

Eighty-eight studies were included. Definition of the end of life is highly variable as is use of antibiotics in patients approaching end of life. Prescribing decisions are influenced by patient age, primary diagnosis, care setting and therapy goals, although patients' preferences are not always documented or adhered to. Urinary and lower respiratory tract infections are the most commonly reported indications with outcomes in terms of symptom control and survival variably reported. Small numbers of studies reported on adverse events and antimicrobial resistance. Clinicians sometimes feel uncomfortable discussing antibiotic treatment at end of life and would benefit from guidelines to direct care.

CONCLUSIONS

Use of antibiotics in patients approaching the end of life is common although there is significant variation in practice. There are a myriad of intertwined biological, ethical, social, medicolegal and clinical issues associated with the topic.

A multicentre point prevalence survey of hospital antibiotic prescribing and quality indices in the Kurdistan regional government of Northern Iraq: the need for urgent action

BACKGROUND

Rationale antibiotic use is crucial to address antimicrobial resistance (AMR) threats. No study has been undertaken in the Kurdistan Regional Government (KRG) to document current antibiotic use/areas for improvement given the high AMR rates.

RESEARCH DESIGN AND METHODS

Point prevalence survey (PPS), using the Global PPS methodology, was conducted among the three major public hospitals in KRG/northern Iraq from September-December 2019. Prevalence and quality of antibiotic use were assessed using agreed indicators.

RESULTS

Prevalence of antibiotic use was high (93.7%; n = 192/205); third-generation cephalosporins were the most commonly prescribed antibiotics (52.6%; n = 140/266). Reasons for treatment were recorded for only 61.7% (n = 164/266) of antibiotics and high use (89.9%) of parenteral therapy was observed. All therapy was empirical, no stop/review dates were recorded, and no treatment guidelines were available. The majority of the prescribed antibiotics (62%; n = 165/266) were from the WHO Watch list.

CONCLUSION

Prevalence of antibiotic use was high not only versus other hospitals in the region but globally, coupled with significant evidence of sub-optimal prescribing. Swift action is needed to improve future prescribing to reduce AMR. One or two areas should initially be targeted for quality improvement including development of local guidelines, documentation of antibiotic indications, and/or stop/review dates.

Treating infections caused by carbapenemase-producing Enterobacterales (CPE): a pragmatic approach to antimicrobial stewardship on behalf of the UKCPA Pharmacy Infection Network (PIN)

The emergence of carbapenemase-producing Enterobacterales (CPE) as a major cause of invasive infection both within the UK and internationally poses a very real concern for all providers of healthcare. The burden of morbidity and mortality associated with CPE infections is well described. The need for early, targeted, effective and safe antimicrobial therapy remains key for the management of these infected patients yet reliable antimicrobial treatment options remain scarce. In the absence of a universal treatment for these CPE invasive infections, individual treatment options tailored to susceptibilities and severity of infection are required. This working group from within the UK Clinical Pharmacy Association (UKCPA) Pharmacy Infection Network has developed evidence-based treatment recommendations to support infection specialists in managing these complex infections. A systematic review of peer-reviewed research was performed and analysed. We report consensus recommendations for the management of CPE-associated infections. The national expert panel makes therapeutic recommendations regarding the pharmacokinetic and pharmacodynamic properties of the drugs and pharmacokinetic targets, dosing, dosage adjustment and monitoring of parameters for novel and established antimicrobial therapies with CPE activity. This manuscript provides the infection specialist with pragmatic and evidence-based options for the management of CPE infections.

Developing a Sustainable Antimicrobial Stewardship (AMS) Programme in Ghana: Replicating the Scottish Triad Model of Information, Education and Quality Improvement

(1) Background: Our aim was to develop robust and reliable systems for antimicrobial stewardship (AMS) in Keta Municipal Hospital and Ghana Police Hospital. Objectives were to build capacity through training staff in each hospital, establish AMS teams, collect data on antibiotic use and support local quality improvement initiatives. (2) Methods: The Scottish team visited Ghana hospitals on three occasions and the Ghanaian partners paid one visit to Scotland. Regular virtual meetings and email communication were used between visits to review progress and agree on actions. (3) Results: Multi-professional AMS teams established and met monthly with formal minutes and action plans; point prevalence surveys (PPS) carried out and data collected informed a training session; 60 staff participated in training delivered by the Scottish team and Ghanaian team cascaded training to over 100 staff; evaluation of training impact demonstrated significant positive change in knowledge of antimicrobial resistance (AMR) and appropriate antibiotic use as well as improved participant attitudes and behaviours towards AMR, their role in AMS, and confidence in using the Ghana Standard Treatment Guidelines and antimicrobial app. (4) Conclusions: Key objectives were achieved and a sustainable model for AMS established in both hospitals.

Response to the Novel Corona Virus (COVID-19) Pandemic Across Africa: Successes, Challenges, and Implications for the Future

BACKGROUND

The COVID-19 pandemic has already claimed considerable lives. There are major concerns in Africa due to existing high prevalence rates for both infectious and non-infectious diseases and limited resources in terms of personnel, beds and equipment. Alongside this, concerns that lockdown and other measures will have on prevention and management of other infectious diseases and non-communicable diseases (NCDs). NCDs are an increasing issue with rising morbidity and mortality rates. The World Health Organization (WHO) warns that a lack of nets and treatment could result in up to 18 million additional cases of malaria and up to 30,000 additional deaths in sub-Saharan Africa.

OBJECTIVE

Document current prevalence and mortality rates from COVID-19 alongside economic and other measures to reduce its spread and impact across Africa. In addition, suggested ways forward among all key stakeholder groups.

OUR APPROACH

Contextualise the findings from a wide range of publications including internet-based publications coupled with input from senior-level personnel.

ONGOING ACTIVITIES

Prevalence and mortality rates are currently lower in Africa than among several Western countries and the USA. This could be due to a number of factors including early instigation of lockdown and border closures, the younger age of the population, lack of robust reporting systems and as yet unidentified genetic and other factors. Innovation is accelerating to address concerns with available equipment. There are ongoing steps to address the level of misinformation and its consequences including fines. There are also ongoing initiatives across Africa to start addressing the unintended consequences of COVID-19 activities including lockdown measures and their impact on NCDs including the likely rise in mental health disorders, exacerbated by increasing stigma associated with COVID-19. Strategies include extending prescription lengths, telemedicine and encouraging vaccination. However, these need to be accelerated to prevent increased morbidity and mortality.

CONCLUSION

There are multiple activities across Africa to reduce the spread of COVID-19 and address misinformation, which can have catastrophic consequences, assisted by the WHO and others, which appear to be working in a number of countries. Research is ongoing to clarify the unintended consequences given ongoing concerns to guide future activities. Countries are learning from each other.

Supporting global antimicrobial stewardship: antibiotic prophylaxis for the prevention of surgical site infection in low- and middle-income countries (LMICs): a scoping review and meta-analysis

BACKGROUND

The Scottish Antimicrobial Prescribing Group is supporting two hospitals in Ghana to develop antimicrobial stewardship. Early intelligence gathering suggested that surgical prophylaxis was suboptimal. We reviewed the evidence for use of surgical prophylaxis to prevent surgical site infections (SSIs) in low- and middle-income countries (LMICs) to inform this work.

METHODS

MEDLINE, Embase, Cochrane, CINAHL and Google Scholar were searched from inception to 17 February 2020 for trials, audits, guidelines and systematic reviews in English. Grey literature, websites and reference lists of included studies were searched. Randomized clinical trials reporting incidence of SSI following Caesarean section were included in two meta-analyses. Narrative analysis of studies that explored behaviours and attitudes was conducted.

RESULTS

This review included 51 studies related to SSI and timing of antibiotic prophylaxis in LMICs. Incidence of SSI is higher in LMICs, infection surveillance data are poor and there is a lack of local guidelines for antibiotic prophylaxis. Education to improve appropriate antibiotic prophylaxis is associated with reduction of SSI in LMICs. The random-effects pooled mean risk ratio of SSI in Caesarean section was 0.77 (95% CI: 0.51-1.17) for pre-incision versus post-incision prophylaxis and 0.89 (95% CI: 0.55-1.14) for short versus long duration. Reduction in cost and nurse time was reported in shorter-duration surgical antibiotic prophylaxis.

CONCLUSIONS

There is scope for improvement, but interventions must include local context and address strongly held beliefs. Establishment of local multidisciplinary teams will promote ownership and sustainability of change.

Establishing a baseline for a national paediatric antimicrobial stewardship programme

BACKGROUND

The majority of antimicrobial stewardship programmes focus on prescribing in adult populations; however, there is a recognized need for targeted paediatric antimicrobial stewardship to improve the quality and safety of prescribing amongst this patient group.

OBJECTIVES

To describe the current epidemiology of antimicrobial prescribing in paediatric inpatient populations in Scotland to establish a baseline of evidence and identify priority areas for quality improvement to support a national paediatric antimicrobial stewardship programme.

METHODS

A total of 559 paediatric inpatients were surveyed during the Scottish national point prevalence survey of healthcare-associated infections and antimicrobial prescribing, 2016. The prevalence of antimicrobial prescribing was calculated and characteristics of antimicrobial prescribing were described as proportions and compared between specialist hospitals and paediatric wards in acute hospitals.

RESULTS

Prevalence of antimicrobial use in paediatric inpatients was 35.4% (95% CI = 31.6%-39.4%). Treatment of community- and hospital-acquired infections accounted for 47.1% and 20.7% of antimicrobial use, respectively, with clinical sepsis being the most common diagnosis and gentamicin the most frequently prescribed antimicrobial for the treatment of infection. The reason for prescribing was documented in the notes for 86.5% of all prescriptions and, of those assessed for compliance against local policy, 92.9% were considered compliant.

CONCLUSIONS

Data from national prevalence surveys are advantageous when developing antimicrobial stewardship programmes. Results have highlighted differences in the prescribing landscape between paediatric inpatient populations in specialist hospitals and acute hospitals, and have informed priorities for the national antimicrobial stewardship programme, which reinforces the need for a targeted paediatric antimicrobial stewardship programme.

Mechanisms affecting the implementation of a national antimicrobial stewardship programme; multi-professional perspectives explained using normalisation process theory

BACKGROUND

Antimicrobial stewardship (AMS) describes activities concerned with safe-guarding antibiotics for the future, reducing drivers for the major global public health threat of antimicrobial resistance (AMR), whereby antibiotics are less effective in preventing and treating infections. Appropriate antibiotic prescribing is central to AMS. Whilst previous studies have explored the effectiveness of specific AMS interventions, largely from uni-professional perspectives, our literature search could not find any existing evidence evaluating the processes of implementing an integrated national AMS programme from multi-professional perspectives.

METHODS

This study sought to explain mechanisms affecting the implementation of a national antimicrobial stewardship programme, from multi-professional perspectives. Data collection involved in-depth qualitative telephone interviews with 27 implementation lead clinicians from 14/15 Scottish Health Boards and 15 focus groups with doctors, nurses and clinical pharmacists (n = 72) from five Health Boards, purposively selected for reported prescribing variation. Data was first thematically analysed, barriers and enablers were then categorised, and Normalisation Process Theory (NPT) was used as an interpretive lens to explain mechanisms affecting the implementation process. Analysis addressed the NPT questions 'which group of actors have which problems, in which domains, and what sort of problems impact on the normalisation of AMS into everyday hospital practice'.

RESULTS

Results indicated that major barriers relate to organisational context and resource availability. AMS had coherence for implementation leads and prescribing doctors; less so for consultants and nurses who may not access training. Conflicting priorities made obtaining buy-in from some consultants difficult; limited role perceptions meant few nurses or clinical pharmacists engaged with AMS. Collective individual and team action to implement AMS could be constrained by lack of medical continuity and hierarchical relationships. Reflexive monitoring based on audit results was limited by the capacity of AMS Leads to provide direct feedback to practitioners.

CONCLUSIONS

This study provides original evidence of barriers and enablers to the implementation of a national AMS programme, from multi-professional, multi-organisational perspectives. The use of a robust theoretical framework (NPT) added methodological rigour to the findings. Our results are of international significance to healthcare policy makers and practitioners seeking to strengthen the sustainable implementation of hospital AMS programmes in comparable contexts.

Antimicrobial point prevalence surveys in two Ghanaian hospitals: opportunities for antimicrobial stewardship

BACKGROUND

Improved knowledge regarding antimicrobial use in Ghana is needed to reduce antimicrobial resistance (AMR). This includes point prevalence studies (PPSs) in hospitals. Objectives were to: (i) provide baseline data in two hospitals [Keta Municipal Hospital (KMH) and Ghana Police Hospital (GPH)] and identify priorities for improvement; (ii) assess the feasibility of conducting PPSs; and (iii) compare results with other studies.

METHODS

Standard PPS design using the Global PPS paper forms, subsequently transferred to their template. Training undertaken by the Scottish team. Quality indicators included: rationale for use; stop/review dates; and guideline compliance.

RESULTS

Prevalence of antibiotic use was 65.0% in GPH and 82.0% in KMH. Penicillins and other β-lactam antibiotics were the most frequently prescribed in both hospitals, with third-generation cephalosporins mainly used in GPH. Antibiotic treatment was mainly empirical and commonly administered intravenously, duration was generally short with timely oral switching and infections were mainly community acquired. Encouragingly, there was good documentation of the indications for antibiotic use in both hospitals and 50.0%-66.7% guideline compliance (although for many indications no guideline existed). In addition, almost all prescribed antibiotics had stop dates and there were no missed doses. The duration of use for surgical prophylaxis was generally more than 1 day (69.0% in GPH and 77.0% in KMH).

CONCLUSIONS

These two hospitals were the first in Ghana to use the Global PPS system. We found the PPS was feasible, relatively rapid and achieved with limited training. Targets for improvement identified included reduction of broad-spectrum antibiotics and duration of treatment.

Ongoing strategies to improve the management of upper respiratory tract infections and reduce inappropriate antibiotic use particularly among lower and middle-income countries: findings and implications for the future

Introduction: Antibiotics are indispensable to maintaining human health; however, their overuse has resulted in resistant organisms, increasing morbidity, mortality and costs. Increasing antimicrobial resistance (AMR) is a major public health threat, resulting in multiple campaigns across countries to improve appropriate antimicrobial use. This includes addressing the overuse of antimicrobials for self-limiting infections, such as upper respiratory tract infections (URTIs), particularly in lower- and middle-income countries (LMICs) where there is the greatest inappropriate use and where antibiotic utilization has increased the most in recent years. Consequently, there is a need to document current practices and successful initiatives in LMICs to improve future antimicrobial use.Methodology: Documentation of current epidemiology and management of URTIs, particularly in LMICs, as well as campaigns to improve future antimicrobial use and their influence where known.Results: Much concern remains regarding the prescribing and dispensing of antibiotics for URTIs among LMICs. This includes considerable self-purchasing, up to 100% of pharmacies in some LMICs. However, multiple activities are now ongoing to improve future use. These incorporate educational initiatives among all key stakeholder groups, as well as legislation and other activities to reduce self-purchasing as part of National Action Plans (NAPs). Further activities are still needed however. These include increased physician and pharmacist education, starting in medical and pharmacy schools; greater monitoring of prescribing and dispensing practices, including the development of pertinent quality indicators; and targeted patient information and health education campaigns. It is recognized that such activities are more challenging in LMICs given more limited resources and a lack of healthcare professionals.Conclusion: Initiatives will grow across LMICs to reduce inappropriate prescribing and dispensing of antimicrobials for URTIs as part of NAPs and other activities, and these will be monitored.

Optimizing carbapenem use through a national quality improvement programme

Background

Concern about increasing carbapenem and piperacillin/tazobactam use led the Scottish Antimicrobial Prescribing Group (SAPG) to develop national guidance on optimal use of these agents, and to implement a quality improvement programme to assess the impact of guidance on practice.

Objectives

To evaluate how SAPG guidance had been implemented by health boards, assess how this translated into clinical practice, and investigate clinicians' views and behaviours about prescribing carbapenems and alternative agents.

Methods

Local implementation of SAPG guidance was assessed using an online survey. A bespoke point prevalence survey was used to evaluate prescribing. Clinicians' experience of using carbapenems and alternatives was examined through semi-structured interviews. National prescribing data were analysed to assess the impact of the programme.

Results

There were greater local restrictions for carbapenems than for piperacillin/tazobactam. Laboratory result suppression was inconsistent between boards and carbapenem-sparing antibiotics were not widely available. Compliance with local guidelines was good for meropenem but lower for piperacillin/tazobactam. Indication for use was well documented but review/stop dates were poorly documented for both antibiotics. Decisions to prescribe a carbapenem were influenced by local guidelines and specialist advice. Many clinicians lacked confidence to de-escalate treatment. Use of both antibiotics decreased during the course of the programme.

Conclusions

A multifaceted quality improvement programme was used to gather intelligence, promote behaviour change, and focus interventions on the use of carbapenems and piperacillin/tazobactam. Use of these antimicrobials decreased during the programme-a trend not seen elsewhere in Europe. The programme could be generalized to other antimicrobials.

Development and impact of a massive open online course (MOOC) for antimicrobial stewardship

Background

The University of Dundee and the BSAC developed a massive open online course (MOOC) to address the global need for education to support antimicrobial stewardship in low- and middle-income countries.

Methods

An interactive course, Antimicrobial Stewardship: Managing Antibiotic Resistance, was developed and delivered via the FutureLearn© platform. The course ran over four 6 week periods during 2015 and 2016 supported by educators and was evaluated via data on uptake and feedback from learners on impact on clinical practice.

Results

In total, 32 944 people, 70% of them healthcare professionals, from 163 countries joined the course from Europe (49%), Asia (16%), Africa (13%), North America (9%), Australia (8%) and South America (5%). Between 33% and 37% of joiners in each run completed at least one step in any week of the course and 219 participants responded to a post-course survey. The course was rated good or excellent by 208 (95%) of the participants, and 83 (38%) intended to implement stewardship interventions in their own setting. A follow-up survey 6 months later suggested that 49% had implemented such interventions.

Conclusions

The MOOC has addressed a global learning need by providing education free at the point of access, and learning from its development will help others embarking upon similar educational solutions. Initial quantitative and qualitative feedback suggests it has engaged participants and complements traditional educational methods. Measuring its real impact on clinical practice remains a challenge. The FutureLearn© platform offers flexibility for MOOCs to be sustainable through modification to remove educator facilitation but maintain active participant discussion.

Impact of antimicrobial stewardship interventions on Clostridium difficile infection and clinical outcomes: segmented regression analyses

Background

Antimicrobial exposure is associated with increased risk of Clostridium difficile infection (CDI), but the impact of prescribing interventions on CDI and other outcomes is less clear.

Objectives

To evaluate the effect of an antimicrobial stewardship intervention targeting high-risk antimicrobials (HRA), implemented in October 2008, and to compare the findings with similar studies from a systematic review.

Methods

All patients admitted to Medicine and Surgery in Ninewells Hospital from October 2006 to September 2010 were included. Intervention effects on HRA use (dispensed DDD), CDI cases and mortality rates, per 1000 admissions per month, were analysed separately in Medicine and Surgery using segmented regression of interrupted time series (ITS) data. Data from comparable published studies were reanalysed using the same method.

Results

Six months post-intervention, there were relative reductions in HRA use of 33% (95% CI 11-56) in Medicine and 32% (95% CI 19-46) in Surgery. At 12 months, there was an estimated reduction in CDI of 7.0 cases/1000 admissions [relative change -24% (95% CI - 55 to 6)] in Medicine, but no change in Surgery {estimated 0.1 fewer cases/1000 admissions [-2% (95% CI - 116 to 112)]}. Mortality reduced throughout the study period, unaffected by the intervention. In all six comparable studies, HRA use reduced significantly, but reductions in CDI rates were only statistically significant in two and none measured mortality. Pre-intervention CDI rates and trends influenced the intervention effect.

Conclusions

Despite large reductions in HRA prescribing and reductions in CDI, demonstrating real-world impact of stewardship interventions remains challenging.

Development of consensus-based national antimicrobial stewardship competencies for UK undergraduate healthcare professional education

BACKGROUND

Healthcare professionals are involved in an array of patient- and medicine-related stewardship activities, for which an understanding and engagement with antimicrobial stewardship (AMS) is important. Undergraduate education provides an ideal opportunity to prepare healthcare professionals for these roles and activities.

AIM

To provide UK national consensus on a common set of antimicrobial stewardship competencies appropriate for undergraduate healthcare professional education.

METHODS

A modified Delphi approach comprising two online surveys delivered to a UK national panel of 21 individuals reflecting expertise in prescribing and medicines management with regards to the education and practice of nurses and midwives, pharmacists, physiotherapists, and podiatrists; and antimicrobial prescribing and stewardship. Data collection took place between October and December 2017.

FINDINGS

A total of 21 participants agreed to become members of the expert panel, of whom 19 (90%) completed round 1 questionnaire, and 17 (89%) completed round 2. Panelists reached a consensus, with consistently high levels of agreement reached, on six overarching competency statements (subdivided into six domains), and 55 individual descriptors essential for antimicrobial stewardship by healthcare professionals.

CONCLUSION

Due to the consistently high levels of agreement reached on competency statements and their associated descriptors, this competency framework should be used to direct education for undergraduate healthcare professionals, and those working in new clinical roles to support healthcare delivery where an understanding of, and engagement with, AMS is important. Although the competencies target basic education, they can also be used for continuing education.

Results from the third Scottish National Prevalence Survey: is a population health approach now needed to prevent healthcare-associated infections?

BACKGROUND

Healthcare-associated infections (HCAIs) are a major public health concern and a significant cause of morbidity and mortality. A robust and current evidence base that is specific to local, national and Europe-wide settings is necessary to inform the development of strategies to reduce HCAI and contain antimicrobial resistance.

AIM

To measure the prevalence of HCAI and antimicrobial prescribing and identify key priority areas for interventions to reduce the burden of infection.

METHODS

A national rolling point-prevalence survey (PPS) in National Health Service (NHS) acute, NHS non-acute, NHS paediatric, and independent hospitals was carried out between September and November 2016 using the European Centre for Disease Prevention and Control protocol designed for the European PPS.

FINDINGS

The prevalence of HCAI was 4.6%, 2.7%, and 3.2% in acute adults, paediatric and non-acute patient groups, respectively. The most frequent HCAI types reported in adult patients were urinary tract infection and pneumonia. The prevalence of antimicrobial prescribing was 35.7%, 29.3%, and 13.8% in acute adults, paediatric, and non-acute patient groups, respectively. Respiratory, skin and soft tissue, gastrointestinal, and urinary tract infections were the most common infections being treated at the time of survey.

CONCLUSION

HCAI continues to be a public health concern in Scotland. Urinary tract infection and pneumonia continue to place a significant burden on patients and on healthcare delivery, including those that develop in the community and require hospital admission. A broader population health approach which focuses on reducing the risk of infection upstream would reduce these infections in both community and hospital settings.

Reduction in post-operative acute kidney injury following a change in antibiotic prophylaxis policy for orthopaedic surgery: an observational study

OBJECTIVES

Evidence has shown that a prophylactic antibiotic regimen of flucloxacillin and gentamicin for orthopaedic surgery was associated with increased rates of post-operative acute kidney injury (AKI). This resulted in changes in the national antibiotic policy recommendation for orthopaedic surgical prophylaxis. This study aimed to assess whether this change from flucloxacillin and gentamicin to co-amoxiclav was associated with changes in the rates of AKI and Clostridium difficile infection (CDI).

METHODS

An observational study and interrupted time series analyses were used to assess rates of post-operative AKI separately in patients undergoing neck of femur (NOF) repair and other orthopaedic operations that required antibiotic prophylaxis. Incidence rate ratios were used to evaluate changes in CDI rates.

RESULTS

Following the change in policy, from flucloxacillin and gentamicin to co-amoxiclav, there was a relative change in rates of post-operative AKI of -63% (95% CI -77% to -49%) at 18 months in the other orthopaedic operations group. In the NOF repair group, there was no change in the rate of post-operative AKI [-10% (95% CI -35%-15%)] at 18 months. The incident rate ratio for CDI in the other orthopaedic operations group was 0.29 (95% CI 0.09-0.96) and in the NOF repair group was 0.76 (95% CI 0.28-2.08).

CONCLUSIONS

The use of co-amoxiclav for antibiotic prophylaxis in orthopaedic surgery was associated with a decreased rate of post-operative AKI compared with flucloxacillin and gentamicin and was not associated with increased rates of CDI.
