Early prediction model for culture-positive late-onset sepsis in very-low-birth-weight infants
- Design: Prospective cohort study.
- Population: Infants <1,500 g admitted to your NICU.
- Predictors: Gestation, birth weight, central-line days, ventilation, enteral-feed exposure, prior antibiotic use, thrombocytopenia, and unit-specific infection factors.
- Outcomes: Culture-positive late-onset sepsis, time to diagnosis, mortality, antibiotic-days.
- Why it works: High clinical relevance, creates locally applicable antibiotic-stewardship evidence, and can lead to a practical risk score. NICU outbreaks and cross-infection remain important research concerns, as highlighted by a recent systematic review.

Kangaroo mother care dose-response and neurodevelopmental outcome in stable very-preterm or low-birth-weight neonates
- Design: Prospective observational cohort, or quality-improvement intervention if implementation is feasible.
- Exposure: Average daily skin-to-skin contact hours during admission and after discharge.
- Outcomes: Weight gain, exclusive breastfeeding at discharge, hypothermia, sepsis, readmission, and Bayley/Developmental Assessment Scale follow-up at 6 or 12 months corrected age.
- Why it works: Affordable, relevant to resource-constrained units, family-centred, and publishable if follow-up is well maintained.
-
Audit and intervention study to reduce inappropriate antibiotic exposure in the NICU
- Design: Before-and-after study, ideally with a standardized early-onset sepsis assessment pathway and antibiotic stop rule at 36-48 hours for eligible culture-negative infants.
- Population: Babies started on empirical antibiotics in the first 72 hours.
- Primary outcome: Antibiotic-days per 1,000 patient-days.
- Secondary outcomes: Culture-positive sepsis, mortality, necrotizing enterocolitis, fungal sepsis, antimicrobial resistance pattern, and readmission.
- Why it works: Very feasible through routine records and addresses medication safety. A recent systematic review of NICU medication errors supports the continuing need for neonatal medication-safety research.

Association of early feeding advancement practices with feed intolerance and necrotizing enterocolitis in very-low-birth-weight infants
- Design: Prospective cohort comparing a protocolized feed-advancement strategy with existing practice, or a retrospective cohort if reliable records exist.
- Population: Infants <1,500 g or <32 weeks gestation.
- Variables: Timing of trophic feeds, mother’s own milk availability, donor milk or formula exposure, rate of feed increment, fortification timing, and transfusion-related feeding practices.
- Outcomes: Time to full feeds, growth velocity, feed interruptions, Bell stage II or higher NEC, late-onset sepsis, and length of stay.
- Why it works: Focuses on a frequent NICU decision with meaningful patient outcomes and no expensive investigation required.
-
Predictors of post-discharge growth failure and neurodevelopmental delay among NICU graduates born very preterm
- Design: Prospective follow-up cohort.
- Population: Infants <32 weeks, <1,500 g, or those requiring prolonged NICU care.
- Assessments: Anthropometry at discharge, 3, 6, and 12 months corrected age; hearing and vision screening; standardized developmental assessment at 12 months.
- Predictors: Severe intraventricular hemorrhage, bronchopulmonary dysplasia, sepsis, NEC, duration of ventilation, feeding at discharge, maternal education, and follow-up adherence.
- Why it works: Builds a long-term outcome database for your unit and identifies babies needing intensified follow-up.
For a DM thesis, avoid an overly broad title. Define one population, one primary outcome, a feasible recruitment period, and a sample-size calculation before finalizing the protocol. Recent evidence also shows major variation in NICU quality across lower-resource settings, supporting locally generated quality-of-care data such as these topics (
recent review).
