Introduction: While lower respiratory tract infections are the main cause of death for children under 5 globally, only a small proportion of children with respiratory tract infections need antibiotics. Overuse of antibiotics globally is leading to increasing rates of antibiotic resistance. In Kyrgyzstan, healthcare workers regularly prescribe antibiotics when clinical uncertainty is present to err on the side of caution. Targeting antibiotic use with biomarkers of inflammation such as C reactive protein (CRP) testing at the point-of-care test (POCT) has been shown to reduce antibiotic use in general, but only few studies have been done in children and no studies exist from Central Asia. This study aims to assess whether the use of a CRP POCT can safely decrease prescription of antibiotics for children with acute respiratory symptoms in primary level healthcare centres in Kyrgyzstan., Methods and Analysis: Multicentre, open-label, individually randomised, controlled clinical trial with 14 days follow-up (follow-up by phone on days 3, 7 and 14) in rural lowland Chui and highland Naryn regions of Kyrgyzstan. The population are children aged 6 months to 12 years attending the primary level healthcare centres during normal business hours with acute respiratory symptoms. CRP POCT equipment will be supplied to healthcare centres, along with a short training session in CRP use, including the interpretation of results to support the clinical evaluation of the child with acute respiratory infection. The primary outcomes are the proportion of patients prescribed an antibiotic within 14 days of index consultation (superiority analysis) and days to recovery (non-inferiority analysis). Secondary outcomes are antibiotics prescribed at index consultation, reconsultations, hospital admission and vital status within 14 days. Analysis of the first primary outcome, antibiotic use, will be intention to treat using a logistic regression model. Analysis of the second primary outcome, days to recovery, will be per protocol using a linear regression model and a non-inferiority margin of 1 day., Ethics and Dissemination: The study was approved on 18 June 2021 by the Ethics Committee (ref: no. 1) of the National Centre of Maternity and Childhood Care, Bishkek, Kyrgyzstan. The results of the study regardless of the conclusion will be presented at international conferences and published in peer-reviewed scientific medical journals along with policy briefs and technical reports., Trial Registration Number: NCT05195866., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2023.

Background: Training is a common and cost-effective way of trying to improve quality of care in low- and middle-income countries but studies of contextual factors for the successful translation of increased knowledge into clinical change are lacking, especially in primary care. The purpose of this study was to assess the impact of contextual factors on the effect of training rural healthcare workers in Kyrgyzstan and Vietnam on their knowledge and clinical performance in managing pediatric patients with respiratory symptoms., Methods: Primary care health workers in Kyrgyzstan and Vietnam underwent a one-day training session on asthma in children under five. The effect of training was measured on knowledge and clinical performance using a validated questionnaire, and by direct clinical observations., Results: Eighty-one healthcare workers participated in the training. Their knowledge increased by 1.1 Cohen's d (CI: 0.7 to 1.4) in Kyrgyzstan where baseline performance was lower and 1.5 Cohen's d (CI: 0.5 to 2.5) in Vietnam. Consultations were performed by different types of health care workers in Kyrgyzstan and there was a 79.1% (CI 73.9 to 84.3%) increase in consultations where at least one core symptom of respiratory illness was asked. Only medical doctors participated in Vietnam, where the increase was 25.0% (CI 15.1 to 34.9%). Clinical examination improved significantly after training in Kyrgyzstan. In Vietnam, the number of actions performed generally declined. The most pronounced difference in contextual factors was consultation time, which was median 15 min in Kyrgyzstan and 2 min in Vietnam., Discussion and Conclusion: The effects on knowledge of training primary care health workers in lower middle-income countries in diagnosis and management of asthma in children under five only translated into changes in clinical performance where consultation time allowed for changes to clinical practice, emphasizing the importance of considering contextual factors in order to succeed in behavioral change after training.

Background: Respiratory disease and, specifically, pneumonia, is the major cause of mortality and morbidity in young children. Diagnosis of both pneumonia and asthma in primary care rests principally on clinical signs, history taking, and bronchodilator responsiveness. This study aimed to describe clinical practices in diverse global primary care settings concerning differential diagnosis of respiratory disease in young children, especially between pneumonia and asthma., Methods: Health professionals in Greece, Kyrgyzstan, Vietnam, and Uganda were observed during consultations with children aged 2-59 months, presenting with cough and/or difficult breathing. Data were analyzed descriptively and included consultation duration, practices, diagnoses and availability/use of medications and equipment. The study is part of the European Horizon 2020 FRESH AIR project., Results: In total, 771 consultations by 127 health professionals at 74 facilities in the four countries were observed. Consultations were shorter in Vietnam and Uganda (3 to 4 minutes) compared to Greece and Kyrgyzstan (15 to 20 minutes). History taking was most comprehensive in Greece. Clinical examination was more comprehensive in Vietnam and Kyrgyzstan and less in Uganda. Viral upper respiratory tract infections were the most common diagnoses (41.7% to 67%). Pneumonia was diagnosed frequently in Uganda (16.3% of children), and rarely in other countries (0.8% to 2.9%). Asthma diagnosis was rare (0% to 2.8%). Antibiotics were prescribed frequently in all countries (32% to 69%). Short acting β-agonist trials were seldom available and used during consultations in Kyrgyzstan (0%) and Uganda (1.8%), and often in Greece (38.9%) and Vietnam (12.6%)., Conclusions: Duration and comprehensiveness of clinical consultations observed in this study seemed insufficient to guide respiratory diagnosis in young children. Appropriate treatment options may further not be available in certain studied settings. Actions aiming at educating and raising professional awareness, along with developing easy-to-use tools to support diagnosis and a general strengthening of health systems are important goals., Competing Interests: JK reports grants from European Union Horizon 2020 during conduct of the study.

Lower respiratory tract illnesses (LRT-illnesses) in children under 5 years (U5s) are a leading cause of morbidity, hospitalisations and mortality worldwide, particularly in low-income countries. It is pertinent to understand possible inconsistent management. This study explored perceptions and practices among caregivers and health professionals on recurrent LRT-illnesses in U5s. Semi-structured interviews with 13 caregivers to U5s with recurrent LRT-illnesses and with 22 primary care health professional interviews in two rural provinces in Kyrgyzstan were triangulated. Data were thematically analysed. The majority (8/13) of caregivers described their young children as having recurrent coughing, noisy breathing and respiratory distress of whom several had responded positively to acute salbutamol and/or had been repeatedly hospitalised for LRT-illness. Family stress and financial burdens were significant. The health professionals classified young children with recurrent LRT-illnesses primarily with pneumonia and/or a multitude of bronchitis diagnoses. Broad-spectrum antibiotics and supportive medicine were used repeatedly, prescribed by health professionals or purchased un-prescribed by the caregivers at the pharmacy. The health professionals had never applied the asthma diagnosis to U5s nor had they prescribed inhaled steroids, and none of the interviewed caregivers' U5s were diagnosed with asthma. Health professionals and caregivers shared a common concern for the children's recurrent respiratory illnesses developing into a severe chronic pulmonary condition, including asthma. In conclusion, the study identified an inconsistent management of LRT-illnesses in U5s, with exorbitant use of antibiotics and an apparently systemic under-diagnosis of asthma/wheeze. When the diagnosis asthma is not used, the illness is not considered as a long-term condition, requiring preventer/controller medication.
