Endoscopic Studies II: Thoracocentesis

2.3K
Thoracentesis(Thoracocentesis), commonly known as pleural tap, is a medical procedure where a 22 gauge needle is inserted into the pleural space, the area between the lung and chest wall. This procedure is commonly performed to diagnose or treat various respiratory disorders.
Description
Excess pleural fluid or air may accumulate in some respiratory disorders in the thoracic cavity. To treat pleural effusion, a physician conducts thoracentesis by carefully piercing the chest wall and entering...

Cardiopulmonary Resuscitation III: AED Use

1.5K
Introduction to AEDAn Automated External Defibrillator (AED) is a portable medical device that analyzes the heart's rhythm and, if necessary, delivers an electrical shock to help the heart re-establish an effective rhythm during sudden cardiac arrest (SCA). SCA occurs when the heart suddenly and unexpectedly stops beating, leading to a loss of blood flow to the brain and other vital organs. In such emergencies, time is of the essence, and using an AED, combined with Cardiopulmonary...

Summary
This summary is machine-generated.

Introducing phlebotomists in emergency departments (ED) did not reduce waiting times. This intervention increased investigations and overall ED length of stay, despite some improvements in patient flow to short stay units.

Area of Science:

  • Emergency Medicine
  • Healthcare Operations Management
  • Health Services Research

Background:

  • Australian emergency departments (ED) face increasing patient volumes.
  • High patient demand necessitates strategies to improve ED efficiency and patient flow.
  • Phlebotomists were introduced at ED triage to manage increased demand.

Purpose of the Study:

  • To evaluate the impact of introducing phlebotomists at ED triage on patient waiting and disposition times.
  • To assess changes in ED performance metrics before and after the phlebotomist intervention.

Main Methods:

  • Quantitative retrospective comparative study design.
  • Data analyzed from two periods: T1 (Jan-Jun 2021) and T2 (Jan-Jun 2023).
  • Included 90,020 total ED presentations, comparing pre- and post-intervention metrics.

Main Results:

  • Short stay unit admissions from triage increased (3.1% to 5.9%, p<0.001).
  • Proportion of patients transferred to cubicles decreased (78.8% to 76.4%).
  • However, 'Did not Wait' rates rose (9.8% to 11.5%), waiting room times increased (80.02 to 112.91 min), and overall ED length of stay (EDLOS) significantly increased (305.1 to 319.4 min).

Conclusions:

  • Phlebotomists at triage did not reduce ED waiting, treatment, or disposition times.
  • The intervention led to increased investigations (blood tests, ECGs) and a longer EDLOS.
  • While patient flow to short stay units improved, overall ED efficiency did not.
