Increasing elderly knowledge about hypertension crisis with audio-visual media

Hypertensive crisis is the most common problem in the elderly resulting from uncontrolled hypertension. A common problem that is a factor causing a hypertensive crisis is ignorance regarding how to treat and prevent the disease, which increases the risk of a hypertensive crisis, so a means of increasing knowledge is needed, namely audio-visual media. The aim of this activity is to increase the elderly's knowledge about hypertensive crises using audio-visual media. The activity was held on December 21, 2023, regarding audio-visual media education about preventing hypertensive crises in the elderly, located at the Mojogedang Mental Revolution House. There were 42 elderly people who took part in the activity in the elderly posyandu area. The pretest results showed that 15 people (35.7%) dominated the elderly's knowledge as poor. The posttest results showed that knowledge of the elderly was dominated by 18 people (42.9%). The marginal homogeneity test obtained a p value of 0.000, which concluded that audio-visual media is an alternative means of increasing the knowledge of the elderly. In conclusion, community service using audio-visual media methods regarding the prevention of hypertensive crises in the elderly significantly helps in increasing the knowledge of the elderly.
