Insights

Healthcare workers in Iran show moderate to high COVID-19 vaccine hesitancy. Key factors influencing this hesitancy include knowledge about the virus and prior vaccination history.

Area of Science:

  • Public Health
  • Epidemiology
  • Vaccinology

Background:

  • Vaccine hesitancy (VH) is a significant barrier to achieving high vaccination coverage, even among healthcare workers (HCWs).
  • Understanding the specific factors contributing to VH among HCWs is crucial for developing targeted interventions.
  • This study focuses on HCWs in Iran, a key population for disease control.

Purpose of the Study:

  • To assess the prevalence and determinants of COVID-19 vaccine hesitancy among healthcare workers in Iran.
  • To identify specific factors associated with vaccine hesitancy in this population.

Main Methods:

  • A cross-sectional descriptive-analytical study was conducted with 551 HCWs from four university hospitals in Zanjan, Iran (2021-2022).
  • Data were collected using a demographic questionnaire and a 36-item COVID-19 VH questionnaire.
  • Statistical analyses included independent-sample t-test, one-way ANOVA, and multiple linear regression.

Main Results:

  • The mean VH score was 96.29 ± 12.88 (range 36-180), with 79.49% experiencing moderate and 17.42% high VH.
  • Significant associations were found between VH and organizational role, chronic disease history, COVID-19 knowledge, vaccination history, and family history of COVID-19 deaths.
  • COVID-19 related knowledge (ß = -0.113) and history of COVID-19 vaccination (β = 0.165) were significant predictors of VH.

Conclusions:

  • COVID-19 vaccine hesitancy is prevalent among Iranian HCWs, ranging from moderate to high.
  • Nurses exhibited the highest levels of vaccine hesitancy.
  • Improving COVID-19 related knowledge and addressing concerns related to vaccination history are critical for reducing hesitancy.

Healthcare Associated Infections II: Preventive Measures

Essential infection prevention measures are based on the knowledge of the infection chain, the modes of transmission in healthcare settings, and the use of the best practices in all healthcare settings. Compulsory public reporting of healthcare-associated infection rates is needed to allow individuals and the community to make informed choices regarding selecting a healthcare facility.
The best practices for preventing healthcare-associated infections include hand hygiene, patient risk...

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...

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,...

Barriers to Effective Communication II

The barriers to effective communication also include cultural barriers, semantic barriers, gender barriers, and time constraints.
Cultural barriers:
Differences in values, beliefs, religion, knowledge, and tradition can significantly impact communication. Awareness of nonverbal cues is critical, especially when conversing with a patient from a different culture. What appears appropriate in one culture may be inappropriate in another.
Semantic barriers:
As a result of their tendency to use...

Issues And Trends In Healthcare Delivery System

The issues and trends in healthcare delivery are constantly changing. The COVID-19 pandemic is one recent issue that wreaked havoc on healthcare systems, causing a shortage of healthcare workers, high demand for medicines and supplies, and increased medical expenditure due to a lack of insurance. Other issues include rising healthcare costs and care fragmentation.
Cost Containment
Payment for healthcare services has historically promoted adoption of costly and often unnecessary or inefficient...
