Abstract
Objective The 6-week postpartum visit (6WPP) is integral in addressing postpartum medical concerns.
Failure to attend this routine visit is a measure of suboptimal care. This study aims
to identify patients at risk of 6WPP nonadherence by developing a novel point-based
risk scoring system.
Methods In this retrospective case–control study (n = 587), a randomly selected subgroup, that is, the “test” group (n = 303), was used to develop the model. The remaining patients were used as an independent
“validation” group (n = 284) to assess the model performance.
Results Five factors were found to correlate with 6WPP nonadherence. Positive correlations
include: Medicaid health insurance (odds ratio [OR]: 2.40, 95% confidence interval
[CI]: 1.38–4.15); prenatal care initiated at ≥ 14 weeks' gestation (OR: 1.82, 95%
CI: 1.11–2.96); and maternal age < 24.0 years (OR: 2.02, 95% CI: 1.13–3.61). Factors
negatively correlated with nonadherence include: “married” marital status (OR: 0.50,
95% CI: 0.30–0.84) and primiparity (OR: 0.51, 95% CI: 0.30–0.85). The final scoring
system demonstrates significant predictive power in both the test and validation groups
(respectively, area under the curve = 0.682, p < 0.001 and 0.629, p < 0.001).
Conclusion This risk assessment tool relies on routinely collected data, making its implementation
simple. Applying it in the clinical setting allows for early, targeted intervention
aimed at minimizing 6WPP nonadherence.
