Insights

Over 15% of hospitalized COVID-19 patients died. Acute respiratory distress syndrome significantly increased mortality risk, highlighting the need for better resource allocation and skilled healthcare providers to manage coronavirus disease.

Area of Science:

  • Infectious Diseases
  • Public Health
  • Critical Care Medicine

Background:

  • COVID-19 presents a significant global health challenge due to complex transmission and lack of definitive treatments.
  • High in-hospital mortality rates for COVID-19 patients, ranging from 1-52%, underscore the severity of the disease.
  • Mortality rates among intensive care unit (ICU) patients with COVID-19 were notably high, between 6-86%.

Purpose of the Study:

  • To systematically review and meta-analyze the prevalence of in-hospital mortality in COVID-19 patients.
  • To identify factors associated with increased mortality risk in hospitalized coronavirus disease patients.

Main Methods:

  • A comprehensive three-stage literature search was performed across PubMed/Medline, Science Direct, and Cochrane Library.
  • Heterogeneity was assessed using forest plots, chi-squared tests, I2 tests, and p-values.
  • Publication bias was evaluated using funnel plots, Egger's correlation, and Begg's regression tests.

Main Results:

  • The meta-analysis revealed a pooled prevalence of 15% (95% CI: 13-17) for in-hospital mortality in coronavirus disease patients.
  • Acute respiratory distress syndrome (ARDS) was a significant risk factor, with patients being eight times more likely to die (RR = 7.99, 95% CI: 4.9-13).

Conclusions:

  • More than fifteen percent of hospitalized COVID-19 patients experienced mortality.
  • Healthcare stakeholders must prioritize resource mobilization and skilled provider deployment to mitigate COVID-19 morbidity and mortality.

Factors Affecting Illness01:18

Factors Affecting Illness

When a person's physical, emotional, intellectual, social development or spiritual functioning is compromised, this deviation from a healthy normal state is called illness. Illness creates stress that in turn harms individuals. Irritation, anger, denial, hopelessness, and fear are behavioral and emotional changes an individual experiences in the phases of illness. A variety of factors influence a person's health and well-being.
For instance, risk factors are connected to illness,...

Pulmonary Embolism II: Diagnostic Studies and Interprofessional Care

Diagnosing Pulmonary EmbolismDiagnosing pulmonary embolism (PE) involves clinical assessment and advanced imaging tests. The preferred diagnostic tool is the spiral (helical) CT scan or CT angiography (CTA), which uses intravenous contrast media to visualize the pulmonary vasculature and identify emboli.A ventilation-perfusion (V/Q) scan is an alternative for patients unable to receive contrast media. This scan includes both perfusion and ventilation scanning. Perfusion scanning involves...

COPD: Pathogenesis and Clinical Features

Chronic obstructive pulmonary disease (COPD) is a group of lung conditions that progressively worsen over time, including chronic bronchitis and emphysema. This cluster of diseases collectively leads to a gradual and irreversible decline in lung function over time.
The primary cause for the onset of COPD is cigarette smoking and exposure to air pollution. These hazardous factors initiate a chain reaction within the lungs, resulting in chronic inflammation, damage to the airways, and a...

Bias in Epidemiological Studies

Biases can arise at various stages of research, from study design and data collection to analysis and interpretation. Recognizing and addressing these biases is essential to ensure the validity and reliability of epidemiological findings.Broadly speaking, biases in epidemiology fall into three main categories: selection bias, information bias, and confounding. A more detailed description of possible biases is:

Factors Affecting the Risk of Infection01:26

Factors Affecting the Risk of Infection

The hosts' susceptibility to infection depends on several factors. The integrity of the skin and mucous membranes helps protect the body against microbial attacks. When the skin is altered, the chance of infection, limb loss, and even death increases.
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin...

Prevalence and Incidence01:08

Prevalence and Incidence

In statistical epidemiology and health sciences, two essential metrics—prevalence and incidence—are fundamental for understanding disease dynamics within a population. These measures enable public health officials, epidemiologists, and researchers to assess the burden of diseases, allocate resources effectively, and design impactful public health policies and interventions.
Prevalence indicates the proportion of individuals in a population who have a specific disease or health...
