Insights

Infant hearing loss is linked to risk factors like NICU stays, low birth weight, and hypoxia. Early screening using Otoacoustic Emission (OAE) and Auditory Brainstem Response (ABR) is effective for detection.

Area of Science:

  • Pediatrics
  • Audiology
  • Neonatology

Background:

  • Hearing loss affects children, with risk factors needing identification in India.
  • Assessing the incidence and common risk factors for pediatric hearing loss is crucial.

Purpose of the Study:

  • To determine the incidence of hearing loss in children.
  • To identify and confirm common risk factors associated with hearing loss in infants.

Main Methods:

  • A cross-sectional study involving 500 infants (≤2 years) was conducted.
  • Hearing screening utilized Transient Evoked Otoacoustic Emission (TEOAE) and Automated Auditory Brainstem Response (AABR).
  • The Joint Committee on Infant Hearing (2007) High-Risk Registry identified infants for screening.

Main Results:

  • 110 infants (22%) were categorized as high-risk.
  • 11 infants (2.2%) exhibited significant hearing loss.
  • Hearing loss was strongly associated with Neonatal Intensive Care Unit (NICU) admission (72.7%), low birth weight (LBW) (54.5%), and hypoxia (54.5%).

Conclusions:

  • Infants with risk factors, particularly NICU admission, LBW, and hypoxia, have a higher incidence of hearing loss.
  • OAE and ABR screening are clinically efficient and cost-effective for early detection of hearing loss in at-risk infants.

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...

Traditional Level Of Health Care System01:26

Traditional Level Of Health Care System

The levels of care describe the services provided in the healthcare system. Accordingly, there are six levels of the traditional healthcare system in the US: preventive, primary, secondary, tertiary, restorative, and continuing healthcare. A nurse must understand how the healthcare industry organizes and provides services within these levels of care.
The preventive healthcare service includes tests for screening. Preventive health care services include identifying and reducing disease risk...

Preventive Healthcare Services01:30

Preventive Healthcare Services

Preventive healthcare services keep people healthy via frequent check-ups, screening, and counseling. They primarily aid in disease prevention rather than treating an acute or chronic illness. Preventive treatment also keeps individuals productive and energetic, allowing them to work well into their retirement years. Examples of preventive care services include:

Secondary Healthcare System01:11

Secondary Healthcare System

Secondary healthcare is offered by a specialist, generally in hospitals or clinics for patients referred by primary healthcare providers. It occurs when a person has an illness or injury that requires specific medical care. Secondary care is often referred to as acute care. Secondary care can range from uncomplicated care to repair a minor laceration or treat a strep throat infection to more complicated emergent care, such as treating a head injury sustained in an automobile accident.

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...
