Actions for Commissioning Teams Management of COPD within primary care June 2012 Actions for Commissioning Teams Why are we looking at this? • COPD exacerbations: 2nd most common cause of emergency admission and one of the most costly inpatient conditions to be treated by the NHS.1 o In the West Midlands: • • • • 94,000 patients diagnosed with COPD (1.6% of population) • In last year, 31,795 emergency COPD admissions (~4% of all emergency admissions) • 3-fold variation in emergency admission rates across West Mids CCGs • Annual prescribing spend on respiratory drugs: £106m (11% of total spend) Major cause of mortality: o DH estimates 23 000 deaths per year in UK attributable to COPD1 o Premature mortality almost double that of EU average2 The missing millions? o Thought to be significant level of underdiagnosis1 o Early diagnosis and optimising interventions in primary care may improve outcomes and reduce costly admissions DH ‘Outcomes Strategy for COPD & asthma’ published in 20112 o Focus on earlier, accurate diagnosis, optimising phamacotherapy, and prolonging survival through appropriate interventions o Optimising the management of COPD should also feature heavily in CCGs Long-term Conditions Strategy 2 Actions for Commissioning Teams What are we covering? The following slides provide selected information on: • Diagnosis • • • • • • o Recommendations from NICE/spirometry/MRC dyspnoea scale Smoking Cessation Pharmacological management of stable COPD o Recommendations from NICE on inhaled and oral therapies o Update on safety advice for tiotropium o Selected points regarding the evidence for inhaled therapies Management of exacerbations o Management in primary care and when to admit to hospital Immunisations NICE recommendations on patient review and selfmanagement Prescribing home oxygen 3 Actions for Commissioning Teams Diagnosis: key points from NICE3 • • • Consider a diagnosis of COPD for people who are over 35, and smokers or ex-smokers*, and have any of these symptoms: o o o o o exertional breathlessness chronic cough regular sputum production frequent winter ‘bronchitis’ wheeze and do not have clinical features of asthma: o chronic unproductive cough, variable breathlessness, night-time wakening Ask about presence of other features: o Weight loss, effort intolerance, waking at night, ankle swelling, fatigue, occupational hazard, chest pain, haemoptysis (note: the last two are uncommon in COPD and raise the possibility of alternative diagnoses) * although bear in mind a significant proportion of patients with COPD may have never smoked (~28% in a recent population study).4 4 Actions for Commissioning Teams Diagnosis: Spirometry • If COPD seems likely, NICE recommend performing spirometry: o Post-bronchodilator spirometry recommended for COPD • e.g. 15 mins after 400 mcg salbutamol; pMDI + spacer is suitable5 o Working definition of COPD: • Airflow obstruction defined as FEV1/FVC ratio < 0.7 • If FEV1 ≥ 80% predicted, a diagnosis of COPD should only be made in the presence of respiratory symptoms (breathlessness or cough) o Post-bronchodilator spirometry also used to grade severity of obstruction and can help guide choice of appropriate inhaled therapy: • Stage 1 - mild: FEV1 ≥ 80% predicted (symptoms also should be present to diagnose COPD in people with mild airflow obstruction). • Stage 2 - moderate: FEV1 50-79%. • Stage 3 - severe: FEV1 30-49% • Stage 4 - very severe: FEV1 < 30% (or FEV1 < 50% but with respiratory failure). o To help early identification, NICE also recommend spirometry in patients > 35 yrs, current or ex-smokers, with chronic cough. Also, consider screening patients with chronic bronchitis. 5 Actions for Commissioning Teams Spirometry • Some points to consider in relation to spirometry… o Have operators received adequate training in spirometry? o Are operators confident to coach spirometry technique to patients and interpret readings? o Are spirometers maintained and adequately calibrated? o Bear in mind that the European Respiratory Society 1993 reference values recommended by NICE may lead to underdiagnosis in older people and are not applicable in black and Asian populations.3 • BTS COPD consortium guide ‘Spirometry in Practice’ recommends reducing predicted values by 7% for Asians and by 13% for AfroCaribbeans and also includes calculations for elderly patients6 6 Actions for Commissioning Teams COPD or asthma or both? • • Resolving the two conditions can be problematic, particularly in older patients. Conditions may co-exist (~ 20% of patients7) Findings that can help identify asthma (from NICE3): o On reversibility testing, there is a large (>400 ml) response to bronchodilators o A large (>400 ml) response to 2 weeks, 30 mg/day oral prednisolone o Serial peak flow measurements showing 20% or greater diurnal/day-to-day variability • • Clinically significant COPD is not present if FEV1 and FEV1/FVC ration return to normal with drug treatment3 Reconsider diagnosis of COPD if a patient reports a marked response to inhaled therapies3 7 Actions for Commissioning Teams • • • Diagnosis: other tests3 As part of initial diagnosis, NICE also recommends: o chest X-ray to exclude other diagnoses (investigate abnormalities using a CT scan) o full blood count to identify anaemia or polycythaemia o BMI calculation Also consider screening for alpha-1 antitrypsin deficiency o Associated with 1-2% of cases; consider screening in younger patients, minimal smoking, or family history Additional investigations may be needed in some circumstances, e.g. o Serial peak flow to help exclude asthma o transfer factor for carbon monoxide (TLCO) or CT scan, to investigate symptoms that seem disproportionate to the spirometric impairment o ECG/echocardiogram if features of cor pulmonale; o pulse oximetry to assess need for oxygen o sputum culture if purulence persistent 8 Actions for Commissioning Teams Grading dyspnoea • NICE recommend use of MRC dyspnoea scale3,8 • • Can help identify patients who may benefit from pulmonary rehabilitation (PR) NICE recommend that PR should be made available to all patients who consider themselves functionally disabled (usually MRC 3 and over), including those who have had a recent hospitalisation for an acute exacerbation. 9 Actions for Commissioning Teams Smoking cessation All COPD patients still smoking, regardless of age, should be encouraged to stop, and offered help to do so, at every opportunity.3 • Smoking cessation has been shown to slow the deterioration in lung function in patients with COPD o Compared with continuation of smoking, rate of decline was approximately halved in participants with mild-to-moderate COPD in one major prospective RCT who quit smoking9) • Nicotine replacement, varenicline or bupropion may be offered, unless contraindicated, combined with appropriate support3 10 Actions for Commissioning Teams Management of stable COPD3 Routinely check a patient’s inhaler technique. Try to identify reasons for non-compliance with inhaled treatments. 11 Actions for Commissioning Teams • Evidence: Risks/benefits of ICS High-dose ICS with LABA widely used in COPD, but are the benefits of the ICS component over-estimated? o Findings from TORCH:10 • 3-year RCT (n= 6,112) comparing LABA/ICS (salmeterol/fluticasone) with placebo, LABA (salmeterol) alone or ICS (fluticasone) alone • No significant reduction in mortality with LABA/ICS compared with placebo • LABA/ICS significantly reduced annual rate of exacerbations compared with LABA alone, but not severe exacerbations requiring hospitalisation • Pneumonia more frequent with LABA/ICS and ICS groups compared with LABA or placebo (19% vs. 13%); NNH = 17 o Findings from 2010 Cochrane review - LABA/ICS vs LABA11 • Compared with LABA alone, LABA/ICS significantly reduced exacerbation rate (18%); also greater improvements in QOL and FEV1. • No significant difference in mortality or hospitalisation rates • Pneumonia occurred more commonly with LABA/ICS: 58% increase BOTTOM LINE: Benefits of ICS need to be viewed against increased risk of side-effects, particularly pneumonia. 12 Actions for Commissioning Teams Tiotropium or LABA(/ICS)? • • For patients experiencing exacerbations or persistent breathlessness (despite use of SABA) there is a choice: o Either a LAMA (currently tiotropium) or a LABA (+ICS if FEV1 is <50% predicted) Regarding the evidence: o NICE Guideline Development Group: concluded no strong evidence to favour LABA over LAMA12 o 2010 Cochrane review: uncertainties in relative benefits of LABA/ICS vs. tiotropium due to shortcomings in trials13 o POET-COPD RCT (2011):14 tiotropium reduced risk of moderate/severe exacerbations compared with salmeterol, but use of ICS in study complicates application in context of NICE o 2012 systematic review: Compared with tiotropium monotherapy, LABA/ICS associated with some improvements in FEV1, QOL and dyspnoea, but no difference in exacerbations, and higher risk of SAEs and pneumonia15 BOTTOM LINE: No strong recommendations to guide choice, but consider suitability of device, tolerability, and adverse effects on ICS. 13 Actions for Commissioning Teams • Evidence for triple therapy Triple therapy (LABA/ICS plus LAMA): o A new option recommended by NICE for patents with persistent breathlessness or persistent exacerbations irrespective of FEV1 o Strength of evidence to support approach has been questioned o Based on most recent systematic review (2012):15 • compared with tiotropium alone, triple therapy associated with clinically significant improvements in lung function and QOL • but non-statistically significant reduction in exacerbations (OR 0.57; 95% CI: 0.24 to 1.37, p = 0.21). • authors concluded that the data “are still scarce and studies too short to generate a strong recommendation”. o Also, Cochrane systematic review (2011):16 • studies inadequate for authors to draw firm conclusions about benefits of triple therapy on mortality, hospitalisation and pneumonia compared with tiotropium or LABA/ICS alone • Small benefits seen in terms of effects on QOL and lung function tests BOTTOM LINE: Triple therapy is a costly treatment option if used inappropriately, and there is uncertainty over long-term benefits 14 Actions for Commissioning Teams Recent safety advice for tiotropium • • MHRA (2010): discrepancies in safety findings for tiotropium Spiriva Handihaler and Respimat devices reported:17 o Numerical excess in mortality, which was statistically significant in patients with known cardiac disorders, found in trials of Respimat▼ o Excess risk not apparent with Handihaler (e.g. 4-yr UPLIFT study tiotropium via Handihaler associated with lower mortality compared with placebo) BMJ meta-analysis (2011):18 o 46% excess risk of all-cause mortality with 5 mcg tiotropium via Resipimat®▼ vs placebo (absolute difference = 0.8%; NNH = 124 (95%CI: 52 to 5682) Current advice from MHRA:17 o Spiriva Respimat▼ should be used with caution in patients with known cardiac rhythm disorders o Remind patients on tiotropium not to exceed the recommended doses o If switch to Handihaler® is being considered, provide training in inhaler technique for the dry power formulation 15 Actions for Commissioning Teams • NICE guidance: oral therapies for stable COPD3 Oral corticosteroids: o Use as regular maintenance therapy not normally recommended. o ..but some patients may require on-going treatment when use cannot be withdrawn following an exacerbation, in which case… • Keep dose as low as possible • Monitor for osteoporosis and prescribe appropriate prophylaxis • Patients aged over 65 should receive prophylaxis without monitoring. Oral theophylline: • • o Reserved for use after trial of bronchodilators, or if unable to use inhaled therapy. o May be combined with either an inhaled beta2-agonist or antimuscarinic; narrow therapeutic window Oral mucolytics: o May be considered for patients with chronic productive cough o Perform trial - continue only if symptomatic improvement. o Do not prescribe routinely for exacerbations in stable COPD Anti-tussive therapy and prophylactic antibiotics are not recommended for stable COPD 16 Actions for Commissioning Teams • Managing exacerbations - treat at home or admit to hospital? 3 Consider the following factors, as recommended by NICE 17 Actions for Commissioning Teams • • Treating exacerbations in primary care3 Increase use of SABAs Unless contraindicated, prescribe oral corticosteroids if significant increase in breathlessness, which is interfering with daily activities o Prescribe prednisolone 30 mg daily for 7 to 14 days (no advantage o • Prescribe antibiotics if more purulent sputum o Patients without more purulent sputum do not need antibiotics o • in >14 days) Consider prophylaxis for osteoporosis in patients requiring frequent course unless consolidation on chest X-ray or clinical signs of pneumonia Sputum culture not recommended in routine practice recommended by NICE Measure oxygen saturation – if SaO2 < 90% treat in hospital 18 Actions for Commissioning Teams Patient review and self-management • Patient review o Frequency of review: • At least annual review in patients at Stages 1 to 3 • At least twice yearly in Stage 4 patients o Record FEV1 and FVC, BMI and MRC score at review (SaO2 also recommended for Stage 4 patients) o Clinical assessment should include: • • • • • smoking status, desire to quit treatment review, inhaler technique need for additional assistance (e.g pulmonary rehabilitation; O2) also nutritional state & presence of depression in Stage 4 patients Self-management of exacerbations o NICE advocates that patients at risk of an exacerbation should be given a course of antibiotic and corticosteroid tablets to keep at home 19 Actions for Commissioning Teams Immunisations • • COPD patients should receive annual flu vaccine3 Pneumococcal vaccination (one-off) also required for patients with COPD:3 o Re-vaccination not recommended but individuals who have previously received 12- or 14-valent PPV or 7-valent PCV should be immunised with 23-valent PPV to gain protection from additional serotypes. 20 20 Actions for Commissioning Teams Supplying oxygen – when to refer • • Home oxygen supply: o significant variation seen in spend across PCTs o Home O2 has been a focus for improvement, e.g. referral of patients to HOS-ARs to assess the initial and on-going needs NICE recommend to refer for O2 assessment:3 o Where airflow obstruction is very severe (FEV1 < 30% predicted) o in patients with cyanosis, polycythaemia, peripheral oedema, or raised jugular venous pressure o If oxygen sats ≤ 92% breathing air o Also, consider referring for assessment if FEV1 30-49% predicted • • Advise patients that O2 should be used for 15 hours per day – greater benefits seen for 20 hours per day Patients on O2 should be reviewed at least once per year by practitioners familiar with long-term O2 21 Actions for Commissioning Teams Supplying oxygen - changes • • Changes to the Home Oxygen Service are underway Home Oxygen Order Form (HOOF) has been separated into HOOF A and HOOF B o HOOF A – designed to be completed by a healthcare professionals: • Non specialists • For temporary orders (static supply only) • Can be used to discharge from hospital o HOOF B: • To be completed ONLY by specialist/commissioned HOS assessment and review service • For static and ambulatory supply 22 Actions for Commissioning Teams • • Supplying Oxygen – commissioning issues Commissioners will need to assess what services are provided for patients currently needing oxygen and who will require oxygen assessment. A small poll of commissioners in the West Midlands has revealed: o Most provide oxygen assessment and review services for patients with COPD o Most provide pulmonary rehabilitation services for patients with COPD o Few (only 1 from the sample of 9 PCTs that responded) provide services for patients with: • • • • Heart failure Paediatric assessment Palliative care Neurological conditions 23 Actions for Commissioning Teams Summary – final key points • Diagnose earlier and accurately: o Based on clinical signs and quality-assured spirometry • In relation to management/prevention of exacerbations: o o o o o o o o Offer smoking cessation at every opportunity Follow NICE sequential approach to pharmacotherapy Check inhaler technique routinely; address non-compliance Exacerbations: treat promptly; offer self-management advice Review patients regularly Offer vaccinations Refer to pulmonary rehabilitation patients with MRC 3 or higher Long-term oxygen therapy: consider patient’s on-going requirements 24 Actions for Commissioning Teams Summary • A final point to consider…(reproduced from the NHS Companion Document on the Outcomes Strategy for COPD1) 25 Actions for Commissioning Teams References 1.
