Evaluation of The Rational Drug Use (RDU) Literacy Among Undergraduate Students

Background: Irrational drug usage is a global concern. WHO recommended a strategy for integrating education and awareness on the rational use of medicine into general education programs. Objective: To evaluate the rational drug use (RDU) literacy among the undergraduate students of Ubon Ratchathani University. Methods: This mixed-methods research consists of a quantitative cross-sectional study with a self-administered RDU literacy questionnaire and a qualitative in-depth interview study. Descriptive statistics and inferential statistics were used in the quantitative study. Thematic analysis was used in the qualitative study. Results: Students who participated in this study included 640 undergraduate students. Approximately half of the participants never studied a RDU-related course (50.94%). Although the findings revealed that most of the participants (73.13%) had good RDU literacy, many participants had less frequency of the right options on some questions (e.g., advertisement of health products). Health sciences students were 2.8 times more likely than non-health sciences students to have good RDU literacy (AOR=2.835, 95% CI: 1.752-4.587). Four main themes were derived from the qualitative study: 1. Definition of RDU; 2. Facilitators; 3. Concerns; 4. RDU country. Conclusion: While the majority of participants demonstrated good RDU literacy, some actually engaged in irrational drug use. Activities promoting RDU literacy among undergraduate students, particularly in faculties other than health sciences, are still required (AU)

Hospitalization and cost after switching from atypical to typical antipsychotics in schizophrenia patients in Thailand.

BACKGROUND: Several clinical practice guidelines suggest using atypical over typical antipsychotics in patients diagnosed with schizophrenia. Nevertheless, cost-containment policy urged restricting usage of atypical antipsychotics and switching from atypical to typical antipsychotics. OBJECTIVE: This study aimed to evaluate clinical and economic impacts of switching from atypical to typical antipsychotics in schizophrenia patients in Thailand. METHODS: From October 2010 through September 2013, a retrospective cohort study was performed utilizing electronic database of two tertiary hospitals. Schizophrenia patients aged 18 years or older and being treated with atypical antipsychotics were included. Patients were classified as atypical antipsychotic switching group if they switched to typical antipsychotics after 180 days of continual atypical antipsychotics therapy. Outcomes were schizophrenia-related hospitalization and total health care cost. Logistic and Poisson regression were used to evaluate the risk of hospitalization, and generalized linear model with gamma distribution was used to determine the health care cost. All analyses were adjusted by employing propensity score and multivariable analyses. All cost estimates were adjusted according to 2013 consumer price index and converted to US$ at an exchange rate of 32.85 Thai bahts/US$. RESULTS: A total of 2,354 patients were included. Of them, 166 (7.1%) patients switched to typical antipsychotics. The adjusted odds ratio for schizophrenia-related hospitalization in atypical antipsychotic switching group was 1.87 (95% confidence interval [CI] 1.23-2.83). The adjusted incidence rate ratio was 2.44 (95% CI 1.57-3.79) for schizophrenia-related hospitalizations. The average total health care cost was lower in patients with antipsychotic switching (-$64; 95% CI -$459 to $332). CONCLUSION: Switching from atypical to typical antipsychotics is associated with an increased risk of schizophrenia-related hospitalization. Nonetheless, association with average total health care cost was not observed. These findings can be of use as a part of evidence in executing prospective cost-containment policy.
