Patients with hypertrophic cardiomyopathy (HCM) and left ventricular outflow tract (LVOT) obstruction who remain symptomatic despite optimal medical therapy may undergo a septal myectomy (Morrow procedure). This procedure involves excising a portion of the hypertrophied septum below the aortic valve using a heart-lung machine to improve blood flow through the LVOT. Effective preoperative and postoperative nursing management ensures successful patient outcomes, minimizes complications, and...

Area of Science:

  • Orthopedic Surgery
  • Geriatric Medicine
  • Medical Informatics

Background:

  • Postoperative complications pose significant risks for elderly patients undergoing total hip replacement.
  • Accurate risk stratification is crucial for optimizing patient management and outcomes.

Purpose of the Study:

  • To develop and validate a predictive nomogram model for postoperative complications in elderly total hip replacement patients.
  • To identify key preoperative and intraoperative risk factors influencing complication rates.

Main Methods:

  • Analysis of 414 elderly patients undergoing total hip replacement.
  • Utilized univariate and multivariate logistic regression to identify independent risk factors.
  • Developed and validated a nomogram using R software for risk prediction.

Main Results:

  • Identified age, renal failure, Type 2 diabetes, and albumin (ALB) as independent risk factors for postoperative complications.
  • The nomogram demonstrated good predictive accuracy with an Area Under the Curve (AUC) of 0.8254.
  • The model showed excellent calibration and passed the Hosmer-Lemeshow goodness of fit test.

Conclusions:

  • A validated nomogram incorporating age, Type 2 diabetes, renal failure, and ALB effectively predicts postoperative complications in elderly hip replacement patients.
  • The developed nomogram offers significant clinical utility for risk stratification and management.
  • This tool aids in improving surgical outcomes for elderly patients undergoing total hip replacement.
