OBJECTIVES: Poison Information and Control Centres (PICCs) are crucial for preventing and managing poisoning cases worldwide. Operating 24/7, they provide emergency care, education, and poisoning trends. However, in many developing countries, PICCs remain underutilized due to limited awareness and resources. The study aimed to assess the knowledge, attitude, and practice (KAP) of healthcare professionals on the PICC of a tertiary care hospital.
METHODS: A questionnaire was developed and validated using a standardized methodology for measure development. Fifteen healthcare experts from various domains assessed content validity, and ten healthcare experts assessed face validity. Items with Content Validity Ratio (CVR), Content Validity Index (CVI), and Item Impact Score less than 0.47, 0.70, and 1.5, respectively, were eliminated. A pilot study was conducted, and Cronbach’s α was calculated. Subsequently, a cross-sectional study was conducted among healthcare professionals of the tertiary care hospital.
RESULTS: A set of 42 items was initially developed, with 14 items in each domain (Knowledge, Attitude, and Practice). Ten items were retained in each domain after content validity. Scale-Content Validity Index (S-CVI) average was calculated to be 0.89. Face validity was assessed both qualitatively and quantitatively, resulting in unanimous agreement and an impact score of 3. Cronbach's alpha was found to be excellent (0.92). A total of 112 healthcare professionals with mean age 30.4 ± 7.45 years, and a median of 2 years of experience in the organization participated in the study. Majority were not aware of the location (58.04%) and helpline number (82.14%) of the PICC. Although majority believed that the PICC can handle poisoning emergencies effectively (79.46%), practical engagement of contacting the PICC remained low (33.04%).
CONCLUSIONS: The validated questionnaire offers a reliable tool to assess knowledge, attitude, and practice of healthcare professionals regarding PICC services. The study also identified significant gaps in knowledge and practice among healthcare professionals regarding the PICC.
