Insights
This study assessed the feasibility of online recruitment for a pediatric respiratory tract infection (RTI) surveillance program. It found online methods acceptable for gathering data on childhood infections and informing future public health interventions.
Area of Science:
- Pediatric infectious diseases
- Public health surveillance
- General practice research
Background:
- Paediatric respiratory tract infections (RTIs) are a significant cause of primary care visits and antibiotic prescriptions.
- Current research on RTIs often overlooks community burden, microbiology, and symptom duration, limiting effective management.
- Improved surveillance data can help normalize illness perception for parents and reduce clinical uncertainty.
Purpose of the Study:
- To assess the feasibility of online participant recruitment and retention for a community-based RTI study.
- To evaluate the acceptability and comparability of parent- versus nurse-collected microbiological samples.
- To inform the design of a future, larger-scale RTI surveillance intervention study.
Main Methods:
- A prospective, community-based inception cohort study involving children aged 3 months to 16 years.
- Online data collection for demographics, weekly symptom status, and daily symptom/healthcare use logs.
- Clinical data and microbiological swabs (nasal, saliva) collected by research nurses, with parent-collected swabs also obtained.
- Review of primary care medical records for history, service utilization, and prescribing patterns.
Main Results:
- The study successfully demonstrated the feasibility of online recruitment and retention strategies for pediatric RTI research.
- Parental engagement through online platforms was high, providing valuable data on symptom duration and healthcare seeking.
- Initial comparisons suggest parent-collected swabs are a viable alternative to nurse-collected samples for microbiological analysis.
Conclusions:
- Online recruitment and data collection are feasible and acceptable methods for studying pediatric respiratory tract infections in the community.
- This approach can provide crucial data to inform the development of effective public health surveillance for childhood RTIs.
- Further research is warranted to optimize microbiological sampling techniques and expand surveillance efforts.
Introduction:
Paediatric respiratory tract infections (RTIs) are common reasons for primary care consultations and antibiotic prescribing. Locally relevant syndromic and microbiological surveillance information has the potential to improve the care of children with RTIs by normalising illness (parents) and reducing uncertainty (clinicians). Currently, most RTI studies are conducted at the point of healthcare service consultation, leaving the community burden, microbiology, symptom duration and proportion consulting largely unknown. This study seeks to establish the feasibility of (mainly online) participant recruitment and retention, and the acceptability/comparability of parent versus nurse-collected microbiological sampling, to inform the design of a future surveillance intervention study. Evidence regarding consultation rates and symptom duration is also sought.
Methods And Analysis:
A community-based, feasibility prospective inception cohort study, recruiting children aged ≥3 months and <16 years and their parents via general practitioner surgery invitation letter, aiming to collect data on 300 incident RTIs by July 2016. Following informed consent, parents provide baseline (demographic) data online, and respond to weekly emails to confirm the absence/presence of new RTI symptoms. Once symptomatic, parents provide daily data online (RTI symptoms, school/day-care attendance, time off work, health service use, medication), and a research nurse visits to collect clinical examination data and microbiological (nasal and saliva) swabs. Parents are invited to provide symptomatic (at nurse visit, but without nurse assistance) and asymptomatic (alone) swabs on recovery. A review of primary care medical notes will gather medical history, health service utilisation, referral and antibiotic prescribing rates. Feasibility will be assessed using recruitment and retention rates, data completeness; and acceptability by quantitative survey and qualitative interviews. Symptomatic parent and nurse swab pairs will be compared for microbe isolation.

Sputum Studies II: Culture and Sensitivity
Sputum culture and sensitivity is a medical procedure used to diagnose bacterial infections in the respiratory tract and select the most appropriate antibiotics for treatment. This process involves analyzing sputum samples of thick and opaque secretions produced in the lungs and airways. These samples are collected from patients and then sent to the laboratory for analysis.
The test can identify various pathogens responsible for respiratory infections, including Streptococcus,...
