Cardiomyopathy VII: Pre and Post Operative Nursing Management01:28

Cardiomyopathy VII: Pre and Post Operative Nursing Management

436
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...

Cardiac Catheterization I: Pre-Procedure Overview

2.8K
Cardiac catheterization is an invasive diagnostic technique used to identify and evaluate structural and functional diseases of the heart and major blood vessels. This technique diagnoses congenital heart disease, coronary artery disease, valvular heart disease, and coronary spasms and assesses ventricular function. It helps guide treatment decisions, including the need for revascularization procedures like percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG) and...

Endoscopic Procedures IV: Sigmoidoscopy and Laproscopy

1.1K
Sigmoidoscopy and laparoscopy are distinct medical procedures that enable physicians to internally inspect different parts of the GI tract. Although they serve different purposes, each is essential for diagnosing and, in some cases, treating various medical conditions.
Sigmoidoscopy
Sigmoidoscopy is a diagnostic procedure that uses a flexible sigmoidoscope equipped with a light source and camera to examine the rectum and sigmoid colon. The procedure involves inserting the tube through the anus...

Preoperative ManagementThe primary goals of preoperative management in kidney transplantation are to optimize the patient’s metabolic state and prepare them for surgery through diet adjustments, necessary dialysis, and tailored medical treatment. This phase also involves comprehensive infection screening and patient education about the surgical procedure and postoperative care to improve outcomes and adherence.Medical ManagementA comprehensive evaluation is required for both the living...

Radiological Investigation III: Pulmonary Angiogram and PET Scan

661
Radiological investigations are paramount in the diagnosis and management of various pulmonary diseases. Two essential investigations are the Pulmonary Angiogram and the Positron Emission Tomography (PET) Scan.
Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...

Pre-Procedural Guidelines for Assessing Blood Pressure01:10

Pre-Procedural Guidelines for Assessing Blood Pressure

958
Accurate blood pressure assessment is crucial for diagnosing and managing various health conditions. To ensure the reliability of these measurements, healthcare professionals must adhere to standardized pre-procedural guidelines. These guidelines enhance patient safety and improve the overall quality of healthcare. The following steps are essential for obtaining accurate and consistent blood pressure readings, from using the appropriate tools to ensuring effective communication with the...

Area of Science:

  • Health Services Research
  • Medical Economics
  • Clinical Practice Guidelines

Background:

  • Increasing utilization of low-value healthcare services, particularly preoperative testing for low-risk procedures, is a growing concern.
  • Preoperative testing for low-risk surgeries may not improve patient outcomes but increases healthcare costs.

Purpose of the Study:

  • To investigate temporal trends in the utilization of preoperative testing for low-risk procedures.
  • To identify patient- and institution-level factors associated with preoperative testing.
  • To assess institutional and regional variation in testing rates.

Main Methods:

  • Retrospective cohort study using linked population-based administrative databases in Ontario, Canada.
  • Inclusion of 1,546,223 adult patients undergoing 2,224,070 low-risk procedures (e.g., endoscopy, ophthalmologic surgery) between April 2008 and March 2013.
  • Hierarchical logistic regression models to analyze factors associated with electrocardiography (ECG), echocardiography, cardiac stress tests, and chest radiography within 60 days pre-procedure.

Main Results:

  • Electrocardiography (ECG) and chest radiography were performed before 31.0% and 10.8% of low-risk procedures, respectively.
  • Significant institutional variation observed, with preoperative ECG rates ranging from 3.4% to 88.8%.
  • Older age, preoperative anesthesia consultation, and preoperative medical consultation were associated with increased likelihood of receiving preoperative ECG and chest radiography.

Conclusions:

  • Preoperative ECG and chest radiography are frequently utilized for low-risk surgical procedures, contrary to guideline recommendations.
  • Substantial variation in testing rates persists across institutions, even after adjusting for patient and institutional factors.
  • There is a need to improve adherence to guidelines for preoperative testing to reduce low-value care.
