3.6 Sampling

The sample size for the study was calculated using the Epicalc 2000 software. A similar study carried out shows that about 20 of homes have good home poison safety measures in place Kimberly E, et al Home Safety in Inner Cities: Prevalence and Feasibility of Home Safety Product Use in Inner City Housing Pediatrics 2007. Setting the significance level at 0.05 with a study power of 90 and assuming an improvement in home poison safety practices level from 20 to 40, the calculated sample size was 108 for each intervention arm. After considering an estimated 30 attrition rate, the sample size was set at 150 for each intervention arm. Random quota sampling of households which fulfil the inclusion and exclusion criteria was carried out. The following are the inclusion criteria for houses selected for the study: 1. Households with children aged 1 to 4 years 2. The respondents have consented to participate 17 Home Safety Practices for Prevention of Poisoning in Young Children 3. The respondents are able to converse in either English or Malay The following are the exclusion criteria for houses selected for the study: 1. Households where only the maidbabysitter is present during the visit The samples were randomly chosen from the Birth Registration Book from Year 2004 till Year 2007. The homes identified were sampled into two intervention arms. Caregivers in Group 1 received intervention package which consists of an immediate post audit feedback, an educational pamphlet and a home safety device while caregivers in Group 2 received intervention package which consists of an immediate post audit feedback and an educational pamphlet.

3.7 Techniques for Data Collection Pre-Testing

Baseline data collection and data collection during each of the subsequent audits were carried out by trained public health nurses using a questionnaire refer Appendix A and an audit checklist refer Appendix B. The questionnaire is used to determine the level of knowledge of caregivers on home poison safety practices including safe storage and safe disposal to prevent accidental poisoning in young children.

3.8 Plan for Data Analysis and Interpretation Include Dummy Tables

SPSS version 15.0 and Epicalc 2000 were used to analyse the results of the study.

4.0 RESULTS

4.1 Results of Evaluation of Safety Device

A total of 133 children and their accompanying caregivers were involved in a sub-study to decide which safety device was more efficacious to be used in the intervention package of the main study. Safety Device 1 is the Patrull DrawerCabinet Lock and Safety Device 2 is the Patrull Multilock. Some of child-caregiver teams were tested on Safety Device 1 only 66, some on Safety Device 2 104 and some were tested on both devices. This sub-study, to validate the home safety device, showed only Safety Device 2 Patrull Multilock to be efficacious which was then used in the intervention package for Kinta District in the main study. A total of 100 96.2 out of 104 children failed to open Safety Device 2 on their first try and 89 89.0 out of 100 children failed to open Safety Device 2 on their second try. All 104 100 accompanying caregivers adults successfully opened Safety Device 2 Table 6. Safety Device 1 was found to be unsuitable as although 62 93.9 out of 66 children failed to open Safety Device 1 on their first try, only 45 72.6 out of 62 children
