Evaluation of computer-assisted self-instructional module for pharmacy continuing education.

A computer-assisted self-instructional module was developed as a method of providing continuing education to pharmacists. A prospective, nonrandomized study was conducted to investigate the effectiveness of computer-assisted instruction (CAI). Using an Apple II microcomputer and anticoagulant therapy as the content base, a series of ten case studies was written and programmed. Twenty-two staff pharmacists from a university hospital and a community hospital participated. Participants were first given a pretest, proceeded through the CAI, took the same test as a posttest, then two weeks later, took a different posttest to measure knowledge retention. The mean test scores before and immediately after the CAI were 55.8% and 80.4%. The mean test score for the two-week posttest was 74%. The mean difference was found to be highly significant for both the pretest and immediate posttest (P less than 0.0001) and the pretest and two-week posttest (P less than 0.001). The study suggested that the use of a CAI module was effective in improving, as well as maintaining, pharmacists' knowledge and that a significant portion of knowledge gained was retained after a period of two weeks. Pharmacists' evaluations of this method of continuing education were generally favorable.

Microbial growth comparisons of five commercial parenteral lipid emulsions.

The ability of parenteral lipid emulsions to support microbial growth was compared using commercially available brands of lipid emulsion. Both 10 and 20% concentrations of soybean and safflower oil emulsions were used. Washed cultures of six gram-negative, three gram-positive, and one yeast, in concentrations of 1 x 10(4) to 2 x 10(4) colony-forming units/ml, were inoculated into lipid emulsion aliquots and stored at room temperature. There were than subcultured at 0, 6, 12, 24 and 48 hr. After 48 hr at 37 degrees C, growth was recorded as colony-forming units/ml. Normalized growth curves were expressed as mean +/- SEM. ANOVA demonstrated no difference in growth patterns due to the nature of the oil or its concentration. Gram-negative organisms multiplied faster when compared to gram-positive (p less than 0.05 at 12 hr, p less than 0.01 at 24 hr, and p less than 0.005 at 48 hr). Yeast grew as well as bacteria. The Center for Disease Control's recommendation of a 12-hr hang time for parenteral lipid emulsions should be observed until correlation of laboratory microbial growth patterns and clinical use are studied further.
