Insights

Code blue (CB) systems improve survival rates for in-hospital cardiac arrests. Patient age, presenting rhythm, and cardiopulmonary resuscitation (CPR) duration significantly impact survival, while system improvements are needed.

Area of Science:

  • Emergency Medicine
  • Cardiology
  • Hospital Administration

Background:

  • Code blue (CB) is a critical hospital alert system for cardiorespiratory arrest response.
  • Patient and event-specific factors influence emergency outcomes.
  • Analysis of CB system effectiveness and associated challenges is essential.

Purpose of the Study:

  • To analyze the survival rate of patients experiencing in-hospital cardiac arrest.
  • To identify factors influencing survival outcomes.
  • To evaluate practical challenges within the code blue system (CBS).

Main Methods:

  • A 24-month audit of all CB calls in a tertiary care hospital was conducted.
  • Data included demographics, diagnosis, arrest details, response times, CPR interventions, and outcomes.
  • Statistical analysis utilized chi-square tests and logistic regression.

Main Results:

  • Out of 720 CB calls, 694 were analyzed (620 true calls, 74 fallacious).
  • Overall survival was 26%; cardiac arrest survival was 11.13%.
  • Significant factors affecting survival included patient age, presenting rhythm, and CPR duration. Personnel and equipment issues were noted.

Conclusions:

  • The code blue system (CBS) enhances resuscitation efforts and survival post-in-hospital cardiac arrest.
  • Patient age, presenting rhythm, and CPR duration are key determinants of survival.
  • Addressing technical and staff-related problems is crucial for CBS optimization.

Hospitals-II

Hospitals provide inpatient and outpatient services. Inpatient services provide care to patients that stay in the hospital for an extended period, ranging from days to months. Examples of inpatient services include intensive care units, hospital wards, or surgeries. Outpatient services provide care to patients who come to a hospital for a diagnostic or treatment but do not stay overnight —for example, diagnostic tests, surgical procedures, or health education.

Hospitals-I

Hospitals offer medical and surgical care to the sick and injured, along with accommodation while they recover. At the same time, they also provide outpatient, emergency, psychiatric, and rehabilitation services to meet various community needs. In addition to providing medical care, hospitals also act as hubs for medical research and training. Hospitals use clinical procedures and evidence-based practice standards to deliver patient care. To deliver safe and efficient care, a nurse must stay up...

Tertiary Healthcare System01:21

Tertiary Healthcare System

Specialized care provided over an extended period is called tertiary care. Usually, a primary or secondary care physician will refer a patient to tertiary care. A patient's maximum physical and mental function is restored in tertiary care, which is caused due to the impact of a chronic illness or condition. Tertiary care aims to achieve the highest level of functioning possible while managing chronic illness. For example, a patient who falls and fractures their hip will need secondary care...

lncRNA - Long Non-coding RNAs

In humans, more than 80% of the genome gets transcribed. However, only around 2% of the genome codes for proteins. The remaining part produces non-coding RNAs which includes ribosomal RNAs, transfer RNAs, telomerase RNAs, and regulatory RNAs, among other types. A large number of regulatory non-coding RNAs have been classified into two groups depending upon their length – small non-coding RNAs, such as microRNA, which are less than 200 nucleotides in length, and long non-coding RNA...

Nomenclature of Secondary and Tertiary Amines01:12

Nomenclature of Secondary and Tertiary Amines

The secondary and tertiary amines are derivatives of ammonia, where two and three of its hydrogens are replaced by alkyl groups, respectively. Secondary and tertiary amines can be symmetrical with identical alkyl groups attached to the nitrogen atom or unsymmetrical when more than one type of alkyl group is present. The standard nomenclature of secondary and tertiary amines is similar to the names given to the primary amines. They are generally named alkylamines. As depicted in Figure 1, for...
