Outcomes
Primary outcome [1] 303355 0
Safety of direct oral amoxicillin challenge of low risk hospital inpatients - patients will be clinically monitored for one hour after their dose of amoxicillin. Clinical outcomes which will be monitored for include rash, change in blood pressure (measured with sphygmomanometer) or heart rate (pulse oximeter), breathing difficulties or wheeze, facial swelling, and any other symptoms patient's report.
Timepoint [1] 303355 0
Patient's will only be monitored for an hour after the dose.
Secondary outcome [1] 338732 0
feasibility of penicillin allergy testing in the acute hospital inpatient setting - this will be monitored in terms of ease of recruiting patients, and administering test amoxicillin doses during a patient's general medical admission, without obstructing their normal care. The outcome will be assessed by means of interviews with medical staff.
Timepoint [1] 338732 0
