Section 1: Introduction Background Welsh Antimicrobial Resistance Programme Surveillance Unit

This report from the Welsh Antimicrobial Resistance Programme Surveillance Unit regarding antimicrobial usage in secondary care is aimed at providing an overview of hospital antimicrobial usage in Wales. The report has had to be selective in what is presented, and concentrates on the major acute hospitals and district general hospitals in Wales. Surveillance of Antimicrobial Usage in Secondary Care

While the use of antimicrobials has revolutionised our ability to treat infections it is associated inevitably with the risk of development and spread of antimicrobial resistance leading to infections that are increasingly difficult to treat, and antimicrobial-associated adverse events, importantly Clostridium difficile-associated disease (CDAD). It has been estimated that 20-50% of antimicrobial use, both in the Community and in Hospitals, is “inappropriate”. This means that patients and society may be exposed to a significant unnecessary risk of resistant infections and CDAD. In addition there is a financial cost, not only in terms of unnecessary antimicrobial use, but also the additional cost of treating resistant infections and CDAD. A key step in improvement of antimicrobial use is the surveillance and assessment of current antimicrobial usage. This can be achieved using a number of complementary methods including: 

Gross surveillance of antimicrobial usage at hospital, specialty or ward/unit level: This can provide comparative information regarding the choice and quantity of agents used, but does not address the indications or appropriateness of antimicrobial use. This current report provides such data at the hospital level and can be used to stimulate more detailed analysis.



Point Prevalence Survey (PPS): In this type of survey, the prescription chart of every patient in a ward or hospital on a set day is checked to see if an antibiotic has been prescribed, and the reasons for the prescription are recorded. This local information about which antibiotics are used and why can be used to target interventions. The Welsh Antimicrobial Resistance Programme is engaged with ECDC, an EU-funded collaboration that, among other projects, supports hospitals in performing comparative PPSs across Europe.



Local unit/ward audits: Audit can be used to explore in detail the indications, dose, duration etc. of antimicrobial prescriptions in order to identify areas for improvement.

It is hoped that access to this data will support:    

Audit patterns of antimicrobial usage Audit of compliance to guidelines and formularies Monitoring the outcomes of interventions. Educational programs

Section 2: Key points of interest Antimicrobial Usage in Secondary Care Antimicrobial usage varies between hospitals in Wales with significant changes over the last 10 years in response to the problem of C. difficile.  Total antibacterial use o In 2014, six of the seventeen individual hospitals reported showed a decrease in total antimicrobial usage, five showed an increase in usage, five showed no significant change in usage compared to the previous year. o No trends in usage could be reported for Singleton hospital as no data was available for the years prior to 2014. o In 2014, the general upward trend in the usage of beta-lactam/betalactamase inhibitor combinations (e.g. co-amoxiclav) ceased, due to significant decreases in usage at several major sites. o The downward trend in usage in the cephalosporin group and in the fluoroquinolones levelled off in 2011, and usage remains relatively unchanged for both. o Carbapenem usage (e.g. meropenem) showed a steady upward trend.  In terms of total antimicrobial use in secondary care across Wales in 2014 o The commonest antibacterial type was beta-lactam/beta-lactamase inhibitor combinations (e.g. co-amoxiclav) which represented 27% of use, followed by broad-spectrum penicillins (e.g. amoxicillin) and macrolides (e.g. clarithromycin) both 10%. o Cephalosporins and fluoroquinolones (e.g. ciprofloxacin) which have been implicated as causes of C. difficile infection represented 4.9% and 5.0% of total antibiotic use respectively. 

There was significant inter-hospital variability in gross annual antimicrobial use in 2014; the lowest use was recorded at Neath Port Talbot hospital (238 DDDs/1000 BD) and highest use at Ysbyty Gwynedd (1511 DDDs/1000BD) when using bed days as a denominator.



If admissions were used as a denominator there was less inter-hospital variability with the lowest usage at Singleton hospital (3250 DDDs/1000AD) and the highest use at University Hospital Llandough (7196 DDD/1000AD).

 There was significant inter-hospital variability in the types of antimicrobials used due to local prescribing policies and case mix. For example see Table 1: Table 1: Inter-hospital variability in antimicrobial usage

Pharmacy data Data sources Antimicrobial ward stock data was extracted from the MEDUSA database. http://www.wales.nhs.uk/sites3/docmetadata.cfm?orgid=428&id=35766 The ward stock data held on pharmacy systems is not primarily intended for analysis of comparative usage and thus there is significant data processing required to standardize the data. Thus the data presented in this report has been coded and measured using the ATC/DDD system. The measure for antimicrobial usage is Defined Daily Doses per 1000 Bed Days (DDD/1000 BD). Bed days have been calculated using in-patient activity (average daily occupied beds) downloaded from Health Solutions Wales Information and Statistics website: e-Quest. http://eproducts.wales.nhs.uk/ “DDD” stands for Defined Daily Dose. DDDs provide a standard measure of drug usage that can be used for international drug utilisation studies. They are administered by the WHO Collaborating Centre for Drug Statistics Methodology at the Norwegian Institute of Public Health which is linked directly to WHO Headquarters in Geneva. http://www.whocc.no/atcddd/. Note: Due to previous technical difficulties with the Morriston pharmacy system, the data for 2005-2012 did not include RETURNS. From 2013 onwards RETURNS are included in the data set and any apparent reductions in usage in Morriston in 2013 may simply be due to the inclusion of RETURNS – interpret data with caution.

Data presented

Pharmacy systems are primarily designed to support stock control and distribution and may be differently configured in different Trusts/Hospitals. In order to increase comparability, the antimicrobial usage data presented in this report only includes the following “issue types” from pharmacy:     

In-patient Scripts (IP Scripts) Patients’ Own Medications (POMs) or One Stop Medications Returns To Take Away (TTA)/Discharge Scripts Ward Requisitions

The main objective of this report is to show trends in antimicrobial usage within the hospital. Thus the dataset does not include the issue types A&E scripts, Clinics, Day cases, Day hospital, OP scripts and Sales usage. We are unable to resolve returns against their original issue type, and only present IP scripts, POMs, returns, TTAs and ward requisitions. Therefore, data presented may be an under representation of true hospital usage if returns were for OP scripts etc. Conversely, the data may represent an over estimate of true in hospital use depending on the amount of POMs and TTA medication taken out of hospital.

Note 1: Only data for oral and parenteral antimicrobial usage are included in this report; it DOES NOT include topical, inhaled, rectal or genital preparation usage. Note 2: Data for Singleton Hospital is INCLUDED in this report from February 2014 onwards. Note 3: The data set for Bronglais hospital is incomplete, and does not include data for the clinical decisions unit (CDU). CDU issues are dispensed to the A&E issue point and cannot be identified and separated from A&E issues. Therefore, the data presented in this report is an UNDERESTIMATE of usage at Bronglais hospital. The data for all other clinical decisions units are included in the relevant hospital data sets.

Data Interpretation In interpreting the data presented in this report it is important to appreciate the ways in which the data is collated and the factors that may drive variability in antimicrobial usage between hospitals. Important issues that should be considered include: 





 

Data applicability. As noted above, the data is drawn from Pharmacy computer systems that are designed primarily for stock control, and which are configured slightly differently in different units. These differences may mean that some antimicrobials that are used out-of-hospital are included in the data. The usage of antimicrobials is standardised against a denominator of patient activity (i.e. 1000 bed days) but may also be influenced by patient case-mix in different hospitals. Thus a hospital which treats significant numbers of immunocompromised patients might be expected to use comparatively larger amounts of broad-spectrum antimicrobials. The usage of antimicrobials should normally reflect the antimicrobial policies of each unit. For example the usage of piperacillin/tazobactam rather than an alternative broad spectrum agent may be a reflection of the hospital policy for the treatment of patients presenting with neutropenic sepsis. The data presented can be used to identify changes in usage and monitor the effect of interventions. When interpreting graphs it is important to note that the y-axis scales vary between graphs and care should be used in interpretation.

Section 4: Antibacterial Usage This section presents hospital antimicrobial stock data, and dispensed prescription data for primary care. It is important to understand the differences in the two data sets in order to interpret the data: Hospital ward stock data held on pharmacy systems is not primarily intended for analysis of comparative usage and thus there is significant data processing required to standardize the data. The data presented in this report has been coded and measured using the ATC/DDD system. The measure for hospital antimicrobial usage is Defined Daily Doses per 1000 Bed Days (DDD/1000 BD). It is important to remember that changes in DDDs may not only reflect changes in the number of patients receiving antibacterials, but also variance in dosage and duration.

Figure 8: Trends in Antibacterial Group Usage 2005-2014 (Skin & Other)

Figure 8 shows the trends in usage for antibacterials that can be used for skin and soft tissue infection, and other agents: beta-lactamase sensitive penicillins (J01CE), beta-lactamase resistant penicillins (J01CF), glycopeptides (J01XA) and lincosamides (J01F):     

Beta-lactamase resistant penicillin usage (J01CF) e.g. flucloxacillin shows an upward trend, with marked summer peaks in usage. Beta-lactamase sensitive penicillin usage (J01CE) e.g. benzylpenicillin shows a downward trend, with marked spring peaks in usage. Glycopeptide usage (J01XA) e.g. vancomycin shows an upward trend. Data from the point prevalence survey suggests that this is largely due to an increase in oral vancomycin. Lincosamide usage (J01F) e.g. clindamycin shows an upward trend. Note: Please note the difference in the y-axis scale which is smaller and finishes at 200 DDD/1000 BD per quarter.

Figure 9: Total antibacterial usage by hospital – DDD/1000 Bed days

The difference in average total antibacterial usage per quarter between the acute hospitals in Wales for 2014 is shown in Figures 9 and 10. Figure 9 shows usage in defined daily doses per 1000 bed days, and a six-fold variation in antibacterial usage between hospitals at either end of the scale; The hospital at the low end of the scale used 238 DDD/1000 BD (Neath Port Talbot), compared to 1511 DDD/1000 BD for the hospital at the high end of the scale (Ysbyty Gwynedd). Figure 10 shows usage in defined daily doses per 1000 admissions, some of the hospitals that appear at the top end of the table have a higher average length of stay and therefore fewer admissions e.g. University Hospital Llandough (P) with the cystic fibrosis unit, and elective orthopaedic surgery unit (CAVOC) have an average length of stay of 7.4 days compared with the acute hospitals of average of 5.7 days.

Figure 25: Morriston Hospital - Antibacterial Usage for 2011 to 2014

Figure 25 shows the pattern of antibacterial usage for Morriston hospital for 2011 (blue bars), 2012 (green bars), 2013 (purple bars) and 2014 (grey bars). In 2014, there was an increase in prescribing of a number of antibacterial groups, including carbapenems (J01DH) and glycopeptides (J01XA). Note: Due to previous technical difficulties with the Morriston pharmacy system, the data for 2005-2012 did not include RETURNS. From 2013 onwards RETURNS are included in the data set and any apparent reductions in usage may simply be due to the inclusion of RETURNS – interpret data with caution.

Figure 27 shows Morriston hospital trends in usage from 2005-2014 for antibacterials that have restricted usage in some/all hospitals in Wales: betalactam/beta-lactamase inhibitor combinations (J01CR), all cephalosporins (J01D), carbapenems (J01DH) and fluoroquinolones (J01MA).     

Beta-lactam/beta-lactamase inhibitor combinations usage (J01CR) shows a marked upward trend, with some large winter peaks. The downward trend cephalosporin usage (J01D) and fluoroquinolone usage (J01MA) levelled off in 2012. Carbapenem usage (J01DH) shows an upward trend. Total antibacterial usage in Morriston has increased over time, with marked variation in the latter years (see Figure 28). The apparent levelling off of usage in 2013/14 may simply be due to the inclusion of RETURNS in the data (data with RETURNS ). 1600 1500
