Clinical Study on Nasal Pressure Injury Prevention in Head and Neck Surgery

A 515-patient historical controlled study evaluates a multidisciplinary quality improvement initiative's impact on nasal pressure injuries from nasotracheal tubes. The dataset includes 221 historical control and 294 intervention group patients, with injury incidence rates and statistical outcomes. Ying Zhou authored the study, published on figshare in April 2026.

Use Cases

• Analyze the relationship between intervention_group status and pressure_injury_incidence using the provided 7.24% vs 2.38% rates.
• Calculate risk metrics like absolute_risk_reduction (4.86%), relative_risk (0.33), and number_needed_to_treat (21) from the study results.
• Examine injury severity by comparing stage_2_injury counts (3 vs 0 cases) between control and intervention periods.
• Assess baseline patient characteristic balance using the reported standardized_mean_differences (all below 0.1).

Strengths

• 515 total patient records provide a substantive clinical sample.
• Clear pre- and post-intervention comparison across two 12-month periods.
• Reported statistical significance (p=0.008) and confidence intervals for key outcomes.

Limitations

• Dataset is a single PDF document (117.4 KB), not structured data for direct analysis.
• Limited to one hospital's patient population, reducing generalizability.
• No raw patient-level data or column details are available for custom modeling.
