This study on obstetric services found that risk-adjusted costs and perinatal mortality rates are linked, with lower costs potentially indicating better outcomes. Cesarean section rates, however, showed no correlation with costs or mortality.

Area of Science:

  • Health Services Research
  • Medical Economics
  • Obstetrics

Background:

  • Evaluating the cost-effectiveness of obstetric services is crucial for healthcare management.
  • Risk adjustment is necessary to compare hospital performance accurately.

Purpose of the Study:

  • To model the cost-effectiveness of obstetric services using two risk-adjustment strategies.
  • To analyze the relationship between risk-adjusted costs, perinatal mortality, and cesarean section rates in urban hospitals.

Main Methods:

  • Employed a two-stage regression analysis for cost risk adjustment, including logistic regression for cesarean section probability and ordinary least squares for length of stay.
  • Utilized perinatal mortality rates adjusted for birthweight, sex, plurality, and race as outcome indicators.

Main Results:

  • Adjusted costs per delivery varied significantly across hospitals (-22% to +31% from the mean).
  • Risk-adjusted costs and perinatal mortality rates showed a positive correlation (r = .69, P = .06).
  • Adjusted cesarean section rates were not correlated with adjusted costs (r = -.03, P = .95) or adjusted perinatal mortality rates (r = -.13, P = .75).

Conclusions:

  • Cost management in obstetric services should prioritize staff levels and mix over practice patterns.
  • Care management should focus on practice patterns influencing patient outcomes.
  • The lowest-cost hospital in the study achieved excellent perinatal outcomes, suggesting cost-effectiveness is achievable.
