E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
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? |
|
E.2.2 | Secondary objectives of the trial |
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. |

E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
All must apply: • Adults (≥18 years) presenting to primary care (general practices) requesting advice for an acute (28 days) cough as the main symptom and; • At least 1 symptom localizing to the lower respiratory tract and suggestive of an acute lower respiratory tract infection (sputum, chest pain, shortness of breath, wheeze) and; • Patient’s first time in the OSAC trial and; • Patient and primary care site are able to consent and randomise the patient by the end of the (working) day of presentation and; • Patient is immunocompetent and; • Patient has capacity and willingness, in the view of the recruiting clinician, to give informed consent and complete the trial paperwork, including the symptom diary, and; • Patient is willing to receive a weekly telephone call from the trial team. |
|
E.4 | Principal exclusion criteria |
The presence of any warrants exclusion: • Age <18 years or; • Patients unable to give informed consent or complete the trial paperwork, including the symptom diary, through mental incapacity, e.g. due to: o Major current psychiatric illness o Learning difficulties o Dementia or; • Patients unwilling to complete the trial symptom diary or unwilling to receive a weekly telephone call from the trial team; • Pregnant or intending to become pregnant (or unwilling to use reliable form of contraception) in the next month or; • Currently breast-feeding/lactating or; • Recruiting primary care site is not the patient's usual practice or if the patient is not expecting to still be with the primary care site in 3 months (i.e. temporary residents) or; • Patient has previously taken part in the OSAC trial or; • Involvement in another clinical drug trial in the last 90 days or any other respiratory related research within the last 30 days or; • Known immune-deficiency (e.g. HIV, active chemotherapy or advanced cancer) or; • Cough >28 days or; • No lower respiratory tract symptoms or signs (sputum, chest pain, shortness of breath, wheeze) or; • Patients with an 'active' diagnosis of asthma (for which treatment has been given in the past 2 years) or; • Patients without a definite history of chickenpox and a recent (≤ 28 days) history of close personal contact with chickenpox or herpes zoster or; • Unable to swallow tablets or; • Clinically very unwell or with symptoms and signs suggestive of pneumonia (as per the British Thoracic Society Guidelines e.g. tachypnoea, unilateral chest signs of consolidation or hypoxia (oxygen saturation <94%) or other systemic infection (e.g. suspected bacteraemia) or; • Patients at higher risk of complications, who according to NICE, warrant immediate antibiotic treatment (NB use of delayed prescription does not preclude OSAC trial participation). These include patients with: o Chronic heart, lung (e.g. chronic obstructive pulmonary disease, bronchiectasis and cystic fibrosis), renal, liver or neuromuscular disease or immunosuppression; or with complications from previous episodes of lower respiratory tract infection (e.g. hospital admission for pneumonia) or; o Patients older than 65 years with two or more of the following criteria, or older than 80 years with one or more of the following criteria: • Unplanned hospitalisation in previous year, • Type 1 or type 2 diabetes • History of cardiac failure • Unable to complete recruitment process by the end of the day of presentation or; • Recent (≤1 month) use of any inhaled corticosteroids or; • Recent (≤1 month) use of any short course (˂1 week) systemic corticosteroids or; • Current or previous (≤12 months) long term (≥ 1 week course) use of systemic steroids or; • Known contra-indications or cautions to oral steroids including: o Uncontrolled diabetes (HbA1c >8%) o Peptic ulcer disease o Previous TB o Known allergy to Prednisolone or other tablet ingredients (potato starch, lactose monohydrate, colloidal silicon dioxide, sodium starch glycolate, magnesium stearate), galactose intolerance, Lapp lactase deficiency or glucose-galactose malabsorption o Suspected ocular herpes simplex o Cushing’s disease o Osteoporosis o Uncontrolled hypertension o Severe affective disorders (e.g. manic depression, previous steroid psychosis) o Glaucoma o Previous steroid myopathy o Epilepsy o Intention to use a live vaccine in the next 3 months o Cardiac failure o Renal impairment o Liver failure o Patients taking other interacting medication (e.g. phenytoin and anti-coagulants) o Any other BNF listed contra-indication Clinicians will be asked to use the British National Formulary (BNF) and their clinical prescribing systems to check for significant interactions for all patients. A SOP will be produced to describe the checking process. |
