Background
Type II diabetes is considered a chronic disease that influences the affected person's
quality of life and imposes a high economic burden on the patient and society. The
enhancement of health literacy seems essential for self-management and disease control
in patients with type II diabetes. Consequently, this study was performed to evaluate
the cost-effectiveness of enhanced health literacy in type II diabetes patients.
Methods
This study was of quantitative and economic evaluation type. A population of 232
patients was selected among those referred to the Tafihan Shiraz clinic based on the
quality of entry and exit. The health literacy educational intervention was carried out
for three months. In order to collect information, researchers used the SF36
questionnaire and the checklist of costs. The Cost Effectiveness Ratio (CER) and
Incremental Cost Effectiveness Ratio (ICER) were calculated. Moreover, the costs of each
unit of increasing the quality of life before and after the intervention were
calculated. A decision was made to determine the cost-effectiveness of the intervention.
Results
According to the results, 40% of the participants were females, and 34.5% were 30-40
years old. Examination of the quality of life in patients before the intervention
indicated that the mean and standard deviation of the patients’ quality of life before
the intervention was 18.43±44.99, and the mean and standard deviation of the quality of
life after the intervention was 49.57±16.21. Moreover, the patients’ quality of life
increased after the educational intervention. The total direct medical costs were
$717,484 and $685,620 before and after the intervention, respectively. The total
indirect medical costs were $604,122 and $493,011 before and after the intervention,
respectively. Moreover, the total indirect costs were $122,535 and $122,119 before and
after the intervention, respectively. The study was cost-effective with CER=0.9 and
ICER= - 140,000 per increase in the quality of life.
Conclusion
Improving health literacy can have a range of benefits and improve the quality of life
of patients with type II diabetes and reduce their treatment costs, and thereby, this
may be seen as an effective step toward the recovery of patients with type II diabetes.
