Clinical Effectiveness of a Nasal Pressure Injury Prevention Initiative

A historical controlled study compares patient outcomes over two 12-month periods before and after a multidisciplinary intervention. The dataset includes results from 515 patients undergoing prolonged oral, head, and neck surgery, authored by Ying Zhou and published in 2026. It reports a significant reduction in nasal pressure injury incidence from 7.24% to 2.38%.

Use Cases

• Analyze the relationship between intervention group assignment and nasal pressure injury incidence rate.
• Model the absolute risk reduction (ARR) and number needed to treat (NNT) based on patient cohort data.
• Compare the distribution of pressure injury stages (e.g., stage 2) between historical control and intervention groups.
• Evaluate the balance of baseline patient characteristics using reported standardized mean differences (SMD).

Strengths

• Results are based on a study of 515 total patients (221 in control, 294 in intervention).
• Reports statistically significant outcomes, including a p-value of 0.008 for reduced injury incidence.
• Provides detailed effect size metrics: absolute risk reduction of 4.86% and relative risk of 0.33.

Limitations

• The underlying patient-level data is not provided; only summary results in a document are available.
• As a 1.3 MB DOCX file, it is a small textual report, not a structured dataset for computational analysis.
• Geographic and institutional context for the study is unspecified, limiting generalizability.
