Guidelines and Strategies for Safe Computer Charting

The guidelines and strategies provided by the American Nurses Association (ANA) and the Canadian Nurses Association (CNA) offer essential principles for ensuring safe and secure computer charting systems in healthcare settings. Let's break down each recommendation:

Feedback Loops

In most cases, excessive hormone production is prevented by negative feedback—a loop that starts with a stimulus inducing the release of a particular substance, like a hormone, to maintain a certain level before triggering a signal that results in a decrease in further release of the hormone.

Open and closed-loop control systems

Control systems are foundational elements in automation and engineering. They are broadly categorized into open-loop and closed-loop systems. These classifications hinge on the presence or absence of feedback mechanisms, significantly influencing the system's performance, complexity, and application.
An open-loop control system operates without feedback from the output. It consists of two primary elements: the controller and the controlled process. The controller receives an input signal...

Positive and Negative Feedback Loops

Animal organs and organ systems constantly adjust to internal and external changes through a process called homeostasis ("steady state"). Examples of these changes include regulation of the level of glucose or calcium in the blood or internal responses to external temperatures. Homeostasis requires  maintaining an internal dynamic equilibrium:

Cell Signaling Feedback Loops

Positive and negative feedback loops are crucial for regulating biological signaling systems. These feedback loops are processes that connect output signals to their inputs.
Negative feedback loops
Most signaling systems have negative feedback loops that can perform different functions such as output limiter, and adaptation.
Output limiter
Upon receiving an input signal, the cellular response rapidly increases until a threshold is reached. Beyond this threshold, a negative feedback loop...

Consider a circular loop with a radius a, that carries a current I. The magnetic field due to the current at an arbitrary point P along the axis of the loop can be calculated using the Biot-Savart law.

Summary

Loop colostomy (LC) is a safe and effective surgical option for anorectal malformations (ARMs), offering comparable outcomes to divided colostomy (DC). This technique simplifies stoma creation and closure, with manageable complication rates in pediatric patients.

Area of Science:

  • Pediatric Surgery
  • Colorectal Surgery
  • Congenital Anomalies

Background:

  • Divided colostomy (DC) is traditionally recommended for anorectal malformations (ARMs) to prevent distal complications.
  • Loop colostomy (LC) presents a technically simpler alternative with potentially similar outcomes.

Purpose of the Study:

  • To evaluate the institutional experience and outcomes of loop colostomy (LC) in patients with anorectal malformations (ARMs).

Main Methods:

  • Retrospective comparative study of 182 patients with ARM undergoing colostomy formation between 2000 and 2015.
  • Data collected included ARM type, associated anomalies, colostomy type, closure time, complications, and urinary tract infections (UTIs).

Main Results:

  • Loop colostomy (LC) was performed in 94% of patients (n=171).
  • Complications occurred in 12% of LCs, with stoma prolapse in 9% requiring revision in 6%.
  • Urinary tract infections (UTIs) were observed in 21% of patients.

Conclusions:

  • Loop colostomy (LC) is the most frequently utilized technique for ARM in this cohort.
  • LC demonstrates comparable complication and outcome rates to divided colostomy (DC).
  • LC is technically easier to perform and close, requiring minimal surgical access.
