Background:
The growth of nurse-delivered care is often required in unstable and conflict-affected health systems due to physician shortages. Nevertheless, there is still a lack of research on the potential benefits of organized nurse-led prenatal care (ANC) in these kinds of environments. We evaluated the clinical outcomes and implementation characteristics associated with a protocol-driven nurse-led ANC model in conflict-affected Yemen.
Methods:
We conducted a prospective cohort study across 12 public primary healthcare facilities in Al-Dhalea, Yemen. Pregnant women aged 15-49 years with a gestational age of ≤ 20 weeks were enrolled in structured nurse-led ANC (n = 224) or routine ANC (n = 226) according to facility capacity. Primary outcomes included follow-up hemoglobin levels and anemia (Hb < 11 g/dL). Secondary outcomes included low birth weight, preterm birth, and NICU admission. Multivariable regression, propensity score matching, difference-in-differences, mediation, and E-value analyses were performed.
Results:
Follow-up was completed for 435 women (96.7%). Nurse-led ANC was associated with higher follow-up hemoglobin (adjusted β = +1.05 g/dL, 95% CI 0.82 to 1.28), lower odds of anemia (adjusted OR = 0.32, 95% CI 0.21 to 0.48), and reduced low birth weight (adjusted OR = 0.62, 95% CI 0.41 to 0.94). The difference-in-differences estimator was +1.12 g/dL (p < 0.001), with parallel trends satisfied (p = 0.42). E-value analysis (2.41) suggested robustness to unmeasured confounding. The model demonstrated characteristics consistent with adaptive nursing leadership across clinical, administrative, and community dimensions.
Conclusion:
Structured nurse-led prenatal care has been linked to better outcomes for mothers and newborns in Yemen affected by war. These results encourage funding for workforce resilience and nurse-led approaches in order to enhance the health system in humanitarian contexts. To prove causation, more studies using cluster-randomized designs are required.

Observational studies are those where the researcher does not intervene but rather observes natural variations. They include cross-sectional, cohort, and case-control studies.
01:30Specialized Care Centers and Settings-II
Rural health centers are specialized care facilities in remote locations with very few medical personnel. The primary care providers who run the centers are mostly Registered Nurse Practitioners. Here, emergency treatment is provided to critically ill or injured patients before they are transferred to the closest hospital. Fortunately, due to advancement in technology, many rural healthcare facilities and professionals have easy access to diagnostic and treatment...

Managed Care System:
The managed care system is designed to control the cost while maintaining the quality of care. The patient's care from admission to discharge is planned by the primary care provider or the case manager, also known as the gatekeeper. In a managed care system, the number of care providers is limited...
