Actuarial Approach

221
The actuarial approach, a statistical method originally developed for life insurance risk assessment, is widely used to calculate survival rates in clinical and population studies. This method accounts for participants lost to follow-up or those who die from causes unrelated to the study, ensuring a more accurate representation of survival probabilities.
Consider the example of a high-risk surgical procedure with significant early-stage mortality. A two-year clinical study is conducted,...

Summary

Phacoemulsification is a more cost-effective cataract surgery than Small Incision Cataract Surgery (SICS). This is based on analyzing Disability-Adjusted Life Years (DALYs) and incremental cost-effectiveness ratios (ICERs) post-surgery.

Area of Science:

  • Ophthalmology
  • Health Economics

Background:

  • Cataracts represent a significant global health burden, ranking as the second most prioritized eye disease worldwide.
  • Surgical intervention is the sole effective treatment for cataracts, presenting substantial healthcare costs.

Purpose of the Study:

  • To conduct a cost-effectiveness analysis of phacoemulsification versus Small Incision Cataract Surgery (SICS).
  • To evaluate surgical procedures using Disability-Adjusted Life Years (DALYs) as the primary effectiveness metric.

Main Methods:

  • An observational analytic study with a prospective design was employed.
  • Data collected from 130 patients undergoing phacoemulsification and 25 patients undergoing SICS.
  • Disability-Adjusted Life Years (DALYs) and Incremental Cost-Effectiveness Ratios (ICERs) were calculated at Day-7 and Day-21 post-surgery.

Main Results:

  • Phacoemulsification yielded DALYs of 0.3204 at both Day-7 and Day-21.
  • SICS resulted in DALYs of 0.3060 at Day-7 and 0.3158 at Day-21.
  • The ICER for phacoemulsification was $1872.49 at Day-7 and $5861.71 at Day-21, compared to the Indonesian GDP of $4174.90.

Conclusions:

  • Phacoemulsification demonstrates superior cost-effectiveness compared to the SICS technique for cataract surgery.
  • The ICER at Day-7 post-surgery indicates a very cost-effective outcome, being less than one GDP per capita per DALY.
