Applications of GIS: Disaster Management and Emergency Response

224
Geographic Information System (GIS) technology is essential for risk identification, action prioritization, and resource optimization in critical situations like flooding and earthquakes. By integrating spatial and demographic data, GIS provides a comprehensive framework for emergency response.GIS integrates data layers, like rainfall intensity, topography, elevation profiles, and river levels, to model high-risk flood zones. These layers assess areas susceptible to flooding based on their...

Methods Of Healthcare Delivery System

3.7K
At the different levels of the healthcare system, we see varying methods of healthcare used. These methods include managed care systems, case management, and primary healthcare.
Managed Care System:
The managed care system is designed to control the cost while maintaining the quality of care. The patient's care from admission to discharge is planned by the primary care provider or the case manager, also known as the gatekeeper. In a managed care system, the number of care providers is...

Issues And Trends In Healthcare Delivery System

5.9K
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...

Rural Health Centers
Rural health centers are specialized care facilities in remote locations with very few medical personnel. The primary care providers who run the centers are mostly Registered Nurse Practitioners. Here, emergency treatment is provided to critically ill or injured patients before they are transferred to the closest hospital. Fortunately, due to advancement in technology, many rural healthcare facilities and professionals have easy access to diagnostic and treatment...

Secondary Healthcare System

1.7K
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. Whatever...

Area of Science:

  • Disaster medicine
  • Health services research
  • Public health

Background:

  • Natural disasters like hurricanes can severely disrupt healthcare delivery.
  • Understanding the impact of different hurricane severities on primary care is crucial for preparedness.

Purpose of the Study:

  • To compare primary care appointment disruptions following Hurricanes Ike and Harvey.
  • To identify patterns in care continuity across these two major weather events.

Main Methods:

  • Analysis of primary care appointment records from Veterans Health Affairs (VA) facilities.
  • Comparison of appointment disposition percentages before, during, and after Hurricanes Ike and Harvey.
  • Inclusion of facilities in affected areas and a comparison group.

Main Results:

  • Hurricane Harvey resulted in greater appointment disruptions: 14% completed during landfall week (vs. 33% for Ike).
  • Care disruptions persisted longer for Harvey, with appointment completion returning to baseline by the third week post-storm (vs. second week for Ike).
  • Comparison clinics maintained higher appointment completion rates throughout both events.

Conclusions:

  • Hurricane Harvey caused more severe and lasting disruptions to primary care compared to Hurricane Ike.
  • Healthcare systems must develop strategies to maintain primary care appointment continuity during catastrophic events.
  • Recognizing the threat of natural disasters and pandemics to preventive care delivery is essential.
