Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: Does the use of oral prednisolone reduce the duration of moderately bad or worse cough and / or the severity of all its associated symptoms on days 2 to 4 by at least 20% when compared to no steroid treatment in adults =18 years presenting to primary care with acute LRTI?;Secondary Objective: In relation to the use of oral steroids compared with no steroid treatment for acute LRTI, we will also: 1. Assess the effects on antibiotic consumption 2. Estimate the cost-effectiveness from the perspectives of the NHS, patients, and society 3. Compare the burden, severity and duration of abnormal peak flow and the following symptoms: cough until 'very little problem'; phlegm; wheeze; fever; chest pain; shortness of breath; sleep disturbance; activity disturbance; and feeling generally unwell 4. Compare adverse events, including reconsultations for documented illness deterioration or hospital admission 5. Investigate if patients’ subjective or objective response to oral steroids is associated with a clinical diagnosis of asthma or COPD 6. Assess patients' satisfaction with treatment and their intention to consult for future similar illnesses.;Primary end point(s): 1. Duration of moderately bad or worse cough (using a validated web/paper based symptom diary) 2. The mean of all symptom severity scores on days 2 to 4 (where day 1 is the day of the index consultation, measured using the symptom diary).;Timepoint(s) of evaluation of this end point: 1. Daily scores, for up to 28 days 2. Daily scores, days 2 to 4 | — |

Total duration and severity of other symptoms (cough until very little problem; phlegm; wheeze; fever; chest pain; shortness of breath; sleep disturbance; activity disturbance; and feeling unwell) and abnormal peak flow (symptom diary) 4. Adverse events including reconsultation for a documented illness deterioration (symptom diary and primary care notes review) 5. Patient satisfaction with treatment and intention to consult for future similar illnesses (symptom diary) 6. Clinical diagnosis of asthma at 3 months (primary care notes review) 7. Quality of life using the EQ-5D (as recommended by NICE, symptom diary) 8. NHS treatment and investigation (e.g. chest x-rays, reconsultation) costs (primary care notes review), out-of-pocket patient costs, and societal cost of time off work (symptom diary). | — |
