Falls are a major cause of morbidity, mortality, and reduced quality of life among elderly individuals, particularly in hospital settings. Preventing falls through effective education is a key component of geriatric care. This study aimed to assess the effectiveness of a pictorial educational booklet on fall preventive measures among elderly patients admitted to selected tertiary care hospitals. A pre-experimental one-group pretest–posttest research design was adopted for the study. A total of 100 elderly patients aged 65 years and above were selected using convenience sampling. Baseline knowledge regarding fall prevention was assessed using a structured knowledge questionnaire. Following the pretest, a pictorial educational booklet on fall preventive measures was administered to the participants. The posttest was conducted after five days using the same tool to evaluate the effectiveness of the educational intervention. The results revealed a significant improvement in the posttest knowledge scores of elderly patients compared to pretest scores, indicating the effectiveness of the pictorial educational booklet. Statistical analysis using paired t-test showed a significant difference at p < 0.05. The study also found a significant association between posttest knowledge scores and selected demographic variables such as age and educational status. The findings of the study suggest that pictorial educational booklets are an effective, simple, and cost-effective method for improving knowledge regarding fall prevention among elderly patients. Incorporating such educational interventions into routine hospital care may help reduce the incidence of falls and enhance patient safety in tertiary care settings.
