The Optimal Antibiotic Treatment Duration for Community-acquired Pneumonia in Adults Diagnosed in General Practice in Denmark (CAP-D)

Phase 4
Recruiting
Conditions
Community-acquired Pneumonia
Interventions
Registration Number
NCT06295120
Lead Sponsor
Research Unit for General Practice in Aalborg
Brief Summary

The aim of this randomised controlled trial is to identify the optimal treatment duration with phenoxymethylpenicillin for community-acquired pneumonia diagnosed in general practice.

Eligible participants are adults (≥18 years) presenting in general practice with symptoms of an acute LRTI (i.e., acute illness (≤ 21 days) usually with cough and minimum one other symptom such as dyspnea, sputum production, wheezing, chest discomfort or fever) in whom the GP finds it relevant to treat with antibiotics.

Consenting patients who meet all the eligibility criteria will be randomised (1:1:1:1:1) to either three, four, five, six or seven days of treatment with phenoxymethylpenicillin 1.2 MIE four times daily.

Primary Outcome Measures
NameTimeMethod
Treatment failure at day 30From randomisation to day 30

Treatment failure is defined as any hospitalisation OR change in the antibiotic strategy (i.e., prolongation of the duration, change in antibiotic type, new antibiotic prescription) due to symptoms of acute respiratory tract infection - between randomisation and day 30.

Secondary Outcome Measures
NameTimeMethod
MortalityFrom randomisation to day 30

All-cause mortality at day 30

The Acute Respiratory Tract Infection Questionnaire (ARTIQ) scoreAt randomisation day and day 8

The Acute Respiratory Tract Infection Questionnaire is a validated, self-administered, multidimensional, sum-scaling symptom score monitoring the severity and functional impact of acute respiratory tract infections in general practice. The questionnaire consists of five single items and 37 items covering five independent dimensions: upper respiratory tract symptoms, lower respiratory tract symptoms, physiological, sleep, and medicine. The participants will be asked to evaluate each item, over the past 24 hours by using a three-point scale: "No (0 point)", "Yes - some (1 point)" or "Yes - a lot (2 points)". Ten items are dichotomized: "Yes (1 point) or "No (0 point)"). The total ARTIQ score is calculated as the sum of each dimension and single items (minimum 0 - maximum 74).

Clinical recovery at day 8From randomisation to day 8

Clinical recovery is defined as: The participant scores below a pre-defined cut-off point for being recovered at the Acute Respiratory Tract Infection Questionnaire OR reports feeling recovered by themselves AND the participant is no longer treated with any antibiotics.

Change in type of antibioticFrom randomisation to day 30

Proportion of participants who had prescribed another type of antibiotic treatment

Relapse of acute Lower Respiratory Tract Infection (LRTI)From randomisation to day 30

Proportion of participants with relapse of acute LRTI

HospitalisationFrom randomisation to day 30

Proportion of participants hospitalised within 30 days

Prolonged antibiotic treatmentFrom randomisation to day 30

Proportion of participants in need of prolonged antibiotic treatment.

ReconsultationFrom randomisation to day 30

Number of reconsultations at general practice or out-off-hour services

New prescriptions within 30 daysFrom randomisation to day 30

Proportion of participants with new prescriptions of symptomatic treatment (e.g. prednisolone, bronchodilator etc) within 30 days

Treatment adherenceFrom randomisation to day 8

Initiation, implementation and discontinuation of the allocated treatment

Adverse eventsFrom randomisation to day 30

Proportion of participants experiencing adverse or serious adverse events
