Properties of DTFT I01:24

Properties of DTFT I

In signal processing, Discrete-Time Fourier Transforms (DTFTs) play a critical role in analyzing discrete-time signals in the frequency domain. Various properties of the DTFTs such as linearity, time-shifting, frequency-shifting, time reversal, conjugation, and time scaling help understand and manipulate these signals for different applications.
The linearity property of DTFTs is fundamental. If two discrete-time signals are multiplied by constants a and b respectively, and then combined to...
Distribution Reliability and Automation01:25

Distribution Reliability and Automation

Distribution reliability in electrical power systems is critical for ensuring an uninterrupted power supply to consumers at minimal cost. According to IEEE Standard Terms, reliability is the probability that a device will function without failure over a specified time period or amount of usage. For electric power distribution, this translates to maintaining continuous power supply and addressing customer concerns over power outages. Several indices, as defined by IEEE Standard 1366-2012, are...
Cut-off Frequency of BJT01:17

Cut-off Frequency of BJT

Cut-off frequencies in Bipolar Junction Transistors (BJTs) mark the transition between the signal's pass band and stop band, influencing their performance in amplifying or attenuating frequencies. These frequencies are crucial for designing BJTs to meet specific operational requirements in electronic circuits.
Alpha Cut-Off Frequency: Pertinent to the common-base configuration, the alpha cut-off frequency defines the upper-frequency limit at which the current gain, alpha, remains stable. As...
Retarders01:19

Retarders

Retarders are chemical admixtures designed to extend the setting time, which is especially useful when there is a delay in sequential concrete pours to prevent cold joints and to achieve a cohesive structure. Retarders, when used in appropriate amounts, can also enhance the architectural appearance of exposed aggregate finishes.
The function of retarders is to delay the setting of concrete, and this effect can be measured using a penetration test. The retardation process involves adding...

Summary

The average transfer time for acute patients from referral to the medical unit was 91.5 minutes. Over a quarter of patients experienced delays exceeding two hours, indicating significant issues in patient transfer times.

Area of Science:

  • Healthcare Management
  • Patient Flow Optimization
  • Emergency Medicine

Background:

  • Efficient patient transfer from the Accident & Emergency (A&E) department to medical units is crucial for timely care.
  • Delays in patient transfer can negatively impact patient outcomes and hospital resource utilization.
  • Understanding transfer times is essential for identifying bottlenecks in the patient journey.

Purpose of the Study:

  • To determine the average transfer time for acute patients from A&E referral to medical unit arrival.
  • To identify if specific time intervals exhibit longer transfer durations.
  • To quantify the proportion of patients experiencing significant transfer delays.

Main Methods:

  • Prospective study including the first 200 consecutive acute patients with complete records.

  • Transfer time calculated as the duration between A&E referral and arrival in the medical unit.
  • Data analyzed to determine average transfer time and identify variations across different time intervals.

    • Main Results:

    • The overall average transfer time was 91.5 minutes.
    • The longest average transfer time (105 minutes) was observed during the 17:00-24:00 interval.
    • 26.5% of patients had transfer times exceeding two hours.

    Conclusions:

    • A significant proportion of acute patients experience unacceptably long transfer times.
    • Patient transfer delays require further investigation to identify root causes.
    • Implementing targeted solutions is necessary to improve patient transfer efficiency and reduce delays.
