Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Training patients to achieve an appropriate Inspiratory Flow Rate (IFR) for the Inhaler Device they use. Verbal training is provided by a pharmacist while utilising an inspiratory flow meter, and is followed up by individualised written instructions on how to achieve the appropriate IFR range for each of the inhalers a patient is using. Verbal training would take between 5-10 minutes until the patient achieves appropriate IFR or the pharmacist determines that the patient is unable to achieve such IFR. Written instructions should be provided 1-2 days after verbal training is offered. All training is offered only once to participants.

Outcomes
Primary outcome [1] 240774 0
% patients with improved shortness of breath (SOB). This is measured on the Borg Dyspnoea Scale.
Timepoint [1] 240774 0
1 week, 2 week, 3 weeks, and 4 weeks after assessment of, or training on, IFR is provided.
Primary outcome [2] 240775 0
Emergency Departmemt (ED) presentation rate. This will be assessed by accessing patients' electronic records that show their presentation rate and admission details.
Timepoint [2] 240775 0
1 month, 2 months, and 3 months following IFR assessment/training.
Primary outcome [3] 240776 0
Average length of stay (in days). This will be assessed by accessing patients' electronic records that show their presentation rate and admission details.
Timepoint [3] 240776 0
Average of all hospital stays over the 3-months period following IFR assessment/training.
Secondary outcome [1] 257449 0
% patients achieving an IFR appropriate for the inhalers they use. This is determined by assessing patients' ability to achieve appropriate IFR, half an hour after training was offered by the pharmacist.
Timepoint [1] 257449 0
Half an hour after training is provided.
Secondary outcome [2] 257450 0

Timepoint [2] 257450 0
Average over the 3-months period following IFR assessment/training.
Secondary outcome [3] 257576 0
Quality of Life as measured by the St George's Respiratory Questionnaire (SGRQ).
Timepoint [3] 257576 0
1 month after intervention.
Secondary outcome [4] 257577 0
Reliever Use Extent (RUE). This describes the extent to which a patient has been using their short acting B-agonist medications, for the relief of their shortness of breath.
Timepoint [4] 257577 0
Daily for 1 month after intervention.
Secondary outcome [5] 257578 0
Mortality rate.
Timepoint [5] 257578 0
3 months, 6 months, 12 months after intervention.

Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Allocation was not concealed.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Simple randomisation by coin tossing is used to allocate a patient to "intervention" group or "no intervention" group, if the patient does not achieve appropriate IFR for at least one inhaler they use, during IFR assessment.
Masking / blinding
