To investigate the effectiveness of addition of recording video of the patient performing inhaler techniques using mobile phone for discussion with the patient, to standard care inhaler education compared to standard care inhaler education alone, in improving inhaler technique of asthma patients.

This is a single-centre, randomized, controlled, parallel group, assessor-blinded trial to evaluate the effectiveness of Personalized Mobile Phone Video Recording in addition to standard care, compared to standard care alone, in improving inhaler technique among patients with asthma.

Patients are randomised to either Personalized Video Recording with standard clinical practice group (intervention) or to standard clinical practice group (control) in 1:1 ratio.

Subject's inhaler technique assessment is performed by using a standard checklist of steps according to the type of inhaler used by subject.

All inhaler technique assessment and asthma control questionnaire will be administered before the intervention/control treatment by a blinded assessor. Both intervention and control treatment will be administered by the same investigators.

Inclusion Criteria:

1. 18 years old and above
2. Informed consent
3. Established clinical diagnosis of asthma by patient's treating doctor
4. Prescribed with inhalers (any type) for therapeutic indication for at least 3 months

Exclusion Criteria:

3. Using spacer/valved holding chamber in addition to MDI
4. Not able to comply with study procedures in the opinion of investigators
5. More than two different types of inhaler which require different techniques

All outcome assessment - inhaler technique assessment and asthma control questionnaire will be administered by a blinded assessor.
