The purpose of this study was to determine if teaching a random sample of patients about their medications and labeling their drug containers with the name of the contents would significantly decrease the number of medication errors made at home. The major hypotheses were based on the expected difFerence in the behavior of patients after the introduction of two variables, planned medication instruction and labeled medications, with respect to the number of errors in medications. These hjq)otheses were rejected on the basis of an F ratio of 1.47 which was not significant at the 5% level. Sub-hypotheses of this study state that there would be a positive relationship between the patient’s age, last grade attended in school, number of medications taken, and the number of errors in medication that he made. The F testing the hypothesis R-0 was 5.99 which was significant at the 1 percent level. The independent variable of importance was the number of medications a patient takes. A t of 3.993 was recorded and was significant at the I percent level. There was no relationship between patient’s age or last grade attended in school and the number of medication errors made. The number of medications taken by the patient was the only variable related to the number of errors he made.
