Factors influencing non-compliance with poison center recommendations.

Non-compliance with prescribed therapies has long been recognized by medical practitioners in all fields as an important factor influencing the probability of a favorable outcome. Few references in the literature address this factor with regard to poisoning. Principles of assessing and improving compliance may also be applied to the advice given by poison information providers. Cases involving lay callers, who failed to comply with poison center recommendations, were studied. The type of advice, reason given for failing to comply, and outcome were assessed. 205 poisoning cases from the 12-mo period were analyzed involving 129 children and 76 adults. In 34 pediatric exposures of children where syrup of ipecac was recommended but not given, 29.4% of parents cited the influence of a family member in deciding not to comply; 47% indicated the potential risk of the exposure was not perceived accurately. In 90 cases of non-compliant referrals of children to emergency departments, 60% of parents minimized the threat of a serious outcome despite explanation of the expected risk. In 76 adult cases, 70 patients refused referral to an emergency department; 26% admitted to sociopsycological reasons, including public status, undisclosed drug abuse, or fear of reprisal. Sequelae developed in 31% of the children and 46% of the adults which may not have occurred if poison center recommendations had been followed. Willingness to comply with a recommended behavior is influenced by factors such as motivation, concern, perceived threat posed by the exposure, and perceived barriers. A compliance model relative to poisoning is needed to reduce risk and promote a favorable outcome.
