Background: Health literacy affects the results of treatment. The rate of readmission recorded to provide the personal information when approaching the medical services and choosing the solutions for the treatment and taking
care of the patient, which is suitable for their health condition.
Objective: This study aims to identify the level of patient’s health literacy by using the Newest Vital Sign (NVS) and defining the relationship factors to patient’s health literacy.
Methods: The cross-sectional study is implemented at a public hospital in the South of Vietnam from November 1st, 2018 to December 31st, 2018. There were 490 patients who admitted to the hospital departments within 24 hours,randomly selected and agreed to participate in the study. The measurement tool named New Vital Sign was translated into Vietnamese, checking for approvales from the specialists and applied to measuring the ability to health literacy of the patients by giving them a form with the information about nutrition from a cream box so that they can read and answer the questions.
The answers were written into the answer form and collecting data. The data processed and analyzed by SPSS software 20.0 versions.
Results: Patients scored as having a high likelihood (50% or more) of limited health literacy: 41.8% Possibility of limited health literacy was 46.9%
ii
Indicates adequate health literacy was 11.2%. The individual capacities relations to health literacy were four items: Age, Education, occupations,personal income.
Conclusion: From the statistical results showed that Near one per ten participants had indicated adequate health literacy. Age, education, personal income, occupation affect to health literacy. This is an important result for health care providers to offer an appropriate health education program.
