Insurance incentives for ambulatory surgery

Area of Science:

• Health Economics
• Surgical Outcomes
• Healthcare Policy

Background:

• Outpatient surgery is increasingly common, raising questions about cost-effectiveness compared to inpatient procedures.
• Insurance policies may influence patient decisions regarding surgical procedures and their settings.

Purpose of the Study:

• To evaluate the cost-effectiveness of outpatient versus inpatient surgical procedures.
• To determine if insurance financial incentives impact the volume of outpatient surgeries.
• To assess the effect of insurance plan design on total healthcare costs.

Main Methods:

• Analysis of insurance policies, focusing on relative user prices for outpatient vs. inpatient surgery and absolute inpatient surgery prices.
• Quantification of insurance plan parameters to assess implications on total care costs.
• Statistical analysis to determine probabilities of surgery and outpatient setting based on insurance composition.

Main Results:

• Lower out-of-pocket payments for ambulatory surgery did not increase the likelihood of procedures being performed in an outpatient setting.
• Increased out-of-pocket payments for surgery, irrespective of the setting, were associated with a reduced overall surgery rate.
• Factors such as patient characteristics and market availability of freestanding surgery firms significantly influence the choice of surgical location.

Conclusions:

• Insurance policies with lower patient cost-sharing for outpatient procedures do not necessarily drive higher adoption rates for ambulatory surgery.
• Higher patient financial responsibility for surgery, in general, acts as a deterrent to undergoing procedures.
• The decision for surgical site selection is multifactorial, involving patient-specific elements and broader market dynamics beyond insurance incentives.
