Common obstacles to recruitment

Medical	• Pneumonia may be a vague diagnosis in hospital practice therefore large numbers of patients with respiratory infection need to be screened to find eligible patients
	• Lack of capacity to give consent
Staff	• Lack of physician ‘buy-in’ and resistance to change
Social	• Hospital stay may be seen as a respite opportunity for some carers
Patient belief	• Some patients believe that they must be 100% better before hospital discharge; some were suspicious of a new or research-based service.
