Background: Fever, a common childhood experience requires correct home management and seeking medical advice at the correct time. The aim of this study was to assess the knowledge and practices of fever home management of a febrile child among the primary caregivers.Methods: A descriptive cross-sectional study was carried out in four randomly selected wards at the Lady Ridgeway Hospital, in Sri Lanka. among 400 primary caregivers of children less than 12 years of age admitted with fever. A pre-tested, pre-coded, interviewer administered questionnaire was used to collect information. Measurement of temperature by the participants were also observed. Results: Normal body temperature was correctly mentioned by 46.2% and mercury thermometer was identified as the best thermometer by 45.8%. Nearly 3/4th stated that the dose of antipyretics should be calculated according to age and or body weight and their knowledge on dose calculations showed that in 70.9% the calculated dose was considered safe and effective. In practice, 54% of the study population had used a thermometer for detection and/or monitoring of fever. Paracetamol was used by 99% of the study population alone or in combination by to treat the febrile child at home before the hospital admission. Non-Steroidal Anti-Inflammatory Drugs were also used by 1.5%. The dose of paracetamol given to the child was too low for 6.5% while it was too high for 24.5%. Statistically significant associations (p<0.05) were seen for correct technique of temperature measurement with higher education, higher family income and having a single child. Conclusions: This study adds to the contemporary fever management literature, by assessing problem from another dimension, which was the knowledge and practices of the primary caregivers in providing home management to a febrile child. Several knowledge and practice gaps were identified, which could be corrected through the clinical and public healthcare system.
