The Importance of COPD
COPD and Public Health Tools• COPD is a complex disease – public health can offer tools to help with evidence- based decision making• The following demonstrate the utility of the tools commonly used in the UK as part of routine public health practice – The first is a needs assessment which maps local needs, demands and service with the evidence- based literature. – The second is to use a population impact assessment tool to help prioritise interventions in COPD. – The third is how to evaluate pharmacists to providing support for evidence-based prescribing in COPD.

Using Population Impact Measures InChronic Obstructive PulmonaryDisease For Prioritisation OfResources In TraffordA. Verma1,2 I.Gemmell1 L.Davies2 R.F.Heller11 University of Manchester2 NHS TraffordJournal of Public Health Vol. 34, No. 1, pp. 83–89 doi:10.1093/pubmed/fdr026
The Population Health Evidence Cycle
Number Needed to Treat (NNT) and the population
Going from the patient to the population• Population Impact Numbers have been designed to take into account the impact of an intervention on the population as a whole• Number of Events Prevented in your Population (NEPP)“the number of events prevented by the intervention in your population”• Size (and characteristics) of your population• Frequency of the condition in your population• Baseline risk of death in next year (or whatever other outcome measure you want to use)• Relative Risk Reduction (from the literature)• Best practice treatment levels (from guidelines)• Current treatment levels in your population
NEPP N * Pe * [Pd *] BR * RRRN = no. of people in population of interestPe = prevalence of the disease in the populationPd = Population with disease (not needed)BR = baseline risk of a cardiac event in 5 yearsRRR = relative risk reduction associated with treatment
Aims In line with the new BTS/NICE guidelines in COPD, we examined the number of admissions prevented in the Trafford population aged over 65 years by increasing the uptake of influenza and pneumococcal vaccination
Data• Population size and incidence – Office of National Statistics – Trafford PCTs data• Relative risk reduction from meta-analyses data – 0.33 for fluvac [Kelly et al 2004] – 0.48 for pneumovac [Nichols 1999]
Results• The current level of immunisation in• >65-year olds for fluvac and pneumovac – 72% and aim to increase this to 90%• The population size for Trafford – Total = 225,000 – Aged >65 = 45,000 – Pe = 90% - 72% = 18% or 0.18 – BR is 4.3 hospitalisations/1000 or 0.0043
An online tool for calculating PIMs has been developed and is available at www.phsim.man.ac.uk
But• Trafford average LOS for COPD – 11.1 days• Cost of a bed day – £300 – Without any intervention
Fluvac Pneumococcal (95%CI) (95% CI) Pe 0.18 0.18 BR 0.0043 0.0043 RRR 0.33 0.48 (0.27-0.38) (0.16-0.62) NEPP 11.5 16.7 (9.3 to 13.8) (8.3-24.7) Potential Cost £38,000 £56,000 saving**The potential cost savings need to be considered in light of other factorse.g. cost of programmes to improve uptake.
Therefore• If we were to increase the vaccine uptake from 72% to 90% in our >65 year population • we would prevent 11.5 and 16.7 admissions/year at a cost saving of £38,000 and £56,000/year• Different populations with differing demographics, immunisation rates and baseline risk will have differing results which will influence policy making decisions
Conclusion The utility of PIMs is to help prioritise and implement national guidelines based on recent evidence and local data by comparing the different cost savings afforded by reducing the number of admission prevented
Are pharmacists reducing COPD’s impactthrough smoking cessation and assessinginhaled steroid use?A. Verma1, A. Harrison1, P. Torun1, J. Vestbo1, R. Edwards2, J. Thornton11 University of Manchester, UK2 University of Otago, New ZealandRespir Med. 2012 Feb;106(2):230-4. Epub 2011 Sep 7.
UK Recommendations• NICE/BTS COPD 2004 guidelines recommend • COPD patients who smoke should be encouraged to stop at every opportunity • Inhaled corticosteroid should be used only among patients with moderate to severe COPD • Pharmacists should identify smokers and provide smoking cessation advice.• Methods • A self-completion questionnaire was sent to 2080 community pharmacists from the 2005 pharmacist census database.
Results• Of the 1051 (50.5%) respondants • 37.1% mentioned COPD as a risk from smoking most or every time • 54.5% sometimes or rarely • 19.6% routinely asked about smoking status when dispensing COPD medication
Results • Pharmacists with more than 20 years experience were more likely to have read the Guideline compared to pharmacists with 10 years or less (OR: 1.54; 95% CI: 1.13 to 2.10) • Pharmacists who had read the NICE Guideline (46.8%) were around twice as likely to mention COPD as a risk of smoking, ask about COPD if inhaled corticosteroids were dispensed and ask about smoking routinely if COPD medication was dispensed. (p<0.005).
Table-1: Community pharmacists’ opinions on improving their knowledge further Yes No % % (95% CI) (95% CI)Need to improve knowledge on 81.1 18.9COPD management (78.6 to 83.4) (16.6 to 21.4)Training would be beneficial 91.5 8.5 (89.7 to 93.1) (6.9 to 10.3)
Table-2: Relationship between reading the COPD Guideline and compliance with the recommendations among community pharmacists Read NICE COPD Guideline Yes No % % (95% CI) (95% CI)Ask about smoking routinely if 27.2 12.9COPD medication dispensed (23.4 to 31.4) (10.3 to 15.9)(n=1036)Ask at least sometimes 11.0 6.0whether COPD/Asthma (8.5 to 14.2) (4.3 to 8.3)diagnosed if inhaledcorticosteroids dispensed(n=1041)Mention COPD at least 49.5 22.1sometimes as a risk from (45.1 to 53.9) (18.7 to 25.8)smoking (n=1042)
Conclusions• NICE guidelines encourage some community pharmacists to carry out smoking cessation and educational interventions – We recommend further dissemination to encourage other pharmacists of their role
Conclusions for the multi-modal approach• Resources are limited and reducing in many aspects of healthcare• A multi-modal approach for COPD is essential • Baseline activity and needs/demands • Prioritisation of interventions • Evaluation of interventions
