Q

What are some of the problems that commonly occur with inhaler use?

A

Not shaking the device before use (inconsistent dosing)
Not priming the aerosol inhaler device (to check the spray is working)
Not breathing out before inhaling (breathing out reduces the amount offer in the airways and increases available space for next breath, what we want)

Q

How should an MDI be taken?

A

Slow and gentle (normal breath, imagine a straight piece of road with a sharp bend at the end, any cars going too fast will crash, the product generates its own propellant)

Q

Patients should always be prescribed…

A

One type of device where possible as concurrent use of multiple types of inhalers with different techniques can confuse patients
Failing that, all aerosols or all dry powders so the same inhalation technique can be used

Temperature 
C&S
32
Q

What are some of the reasons treatment failure may occur?

A

Failure to take medicines as prescribed
Failure to use devices correctly
Failure to use peak flow meter regularly
No action plan
Drug causes, ADR’s
Worsening of underlying disease or acute exacerbation
Depression (common in chronic diseases) leading to non-adherance

What is an ‘asthma action plan (AAP)’?

A

Written and personalised to each individual patient
Includes,
Inhaler/PEF training
Knowledge of drug types

Helps patient recognise worsening asthma and action points e.g. when to, increase dose of inhaled steroids, start oral steroid, seek medical attention etc.

44
Q

In which patients is it critical that they have an AAP?

A

Patients with moderate to severe disease i.e. BTS step 3 or above and/or previous admission

45
Q

What is the use of PEF in asthma management?

A

Allows patient and HCP to monitor asthma control by keeping a PEF diary (available on FP10)

46
Q

PEF measurements are…

A

Effort and technique dependent (should use the best of 3 attempts)
Dependent on sex, age and height

47
Q

What is the aim for PEF measurements in asthma patients?

A

> 70% or 0.7 of predicted normal or best

48
Q

When is a PEF considered ‘normal’?

A

> 80% of predicted normal or best

49
Q

When does a PEF value indicate acute severe asthma?

A

<50%

50
Q

AAP’s are linked to…

A

Improved health outcomes and reduced hospital admissions

51
Q

What is the AAA test?

A

Avoid Asthma Attack test

Asks a series of questions to detect worsening asthma control i.e. night time waking, symptoms, reliever use

52
Q

What does a self-care strategy in a COPD patient look like?

A

Start oral steroids if worsening dyspnoea
Antibiotics if purulent sputum
Increasing bronchodilators if breathless
Oxygen care
Nebuliser care
Pulmonary rehabilitation
Review sedative medications and those that reduce respiratory drive i.e. opiates, benzos, tricyclics etc.

53
Q

When monitoring a patent against their action plan, which factors can we use to determine if they are achieving their treatment aims?

A

PEF for asthma (>70% normal or best) and FEV1% for COPD (declining or stable?)
β-agonist use in asthma
Symptoms
ADR’s
Holistic (depression, effect on daily life)
Smoking
Inhaler technique (review as often as possible)
Review pharmacological treatments in asthma 3 monthly (with a view to step down where possible)
Review pharmacological treatments in COPD at least annually
MUR/NMS in asthma and Asthma Control Test (ACT)
