Introduction: The objective of this paper is to investigate the behavioural intention to use the Poison Information System (PIS) among healthcare professionals based on the extension of the Technology Acceptance Model. Methods: A quantitative approach used a five-point Likert scale questionnaire adapted from previous research. Data were obtained from 136 health professionals working in the Emergency Department of public hospitals in Malaysia. Results: A multiple linear regression model showed that approximately 40% of the variation in intention to use was related to positive attitude, staff category, and inversely to computer anxiety. Perceived usefulness, perceived ease of use, and computer usage were related to intention to use, but their correlation was accounted for by positive attitude, staff category, and computer anxiety. A factor analysis grouped positive attitude, intention to use, and perceived usefulness on Factor I and perceived ease of use, inverse computer anxiety, and computer habit on Factor II. Cluster analysis indicated three clusters. Gender, age, experience, and staff category were strongly inter-related; intention to use clustered with perceived ease of use and perceived usefulness; positive attitude clustered with computer habit; and the latter two clustered together. Conclusion: These findings show that positive attitude, staff category, and computer anxiety of healthcare professionals, working in emergency departments, may have the greatest effect on PIS usage.

The aim of the present paper is to evaluate the Malaysian Toxicological Database (MyToxData), a newly developed system for toxicological data management. MyToxData is a local system for collection of case reporting and toxicity statistics as well as its database of chemical products and toxicity information. An online questionnaire using JotForm was distributed among healthcare professionals in Malaysian hospitals. The participants were asked to perform tasks on MyToxData system before rating their satisfaction experience. The questionnaire was adopted from previous literature and comprised 12 items, each having a five-point scale that ranged from Strongly Disagree to Strongly Agree. The collected data were then analysed using the SPSS software package. Based on the results, the satisfaction testing showed a high satisfaction score for the login at 95.7% and case registration and toxicological/poisoning case notification at 65.2%. The poisoning substance identification component received a 78.2% agreement on the usefulness with a very high acceptance of 91.3% on the treatment and clinical information retrieval made available on the system. One sample t-test found that all constructs for the satisfaction testing of MyToxData, namely, accuracy, content, ease of use, format and timeliness, were significant. The higher acceptance by healthcare professionals on the satisfaction testing of MyToxData has identified the effectiveness of the development and subsequent usage of a dedicated system for toxicological data management.
