International Nursing Organizations I

2.2K
International Nursing Organization (ICN) is a global union of national nurses' organizations. Individual nurses can be a part of ICN through member organizations. Each member organization strives to ensure quality nursing care, sound health policies, the advancement of nursing knowledge, respect for the profession, and a satisfied and competent nursing workforce.
ICN member organizations work to advance the field of nursing and healthcare via policies, partnerships, lobbying, professional...

Introduction to GIS01:28

Introduction to GIS

804
Geographic Information Systems (GIS) are tools for storing, analyzing, and displaying spatial data alongside related attributes. Unlike traditional information systems that address general queries, GIS incorporates spatial components, enabling users to answer "where" and "how far." For example, GIS can process housing data linked to geographic locations like zip codes, allowing insights into population density or housing distribution through thematic maps.GIS integrates technologies such as...

Levels of Use of a GIS

511
Geographic Information Systems (GIS) operate across three levels of application, each representing an increasing degree of complexity: data management, analysis, and prediction. These levels reflect the expanding functionality and versatility of GIS technology in handling spatial data for diverse purposes.Data ManagementAt its foundational level, GIS serves as a tool for data management, enabling the input, storage, retrieval, and organization of spatial data. This level is often employed in...

Selected Data About Geographic Locations

347
Geographic Information Systems (GIS) rely on two core types of data: spatial data and attribute data.Spatial DataSpatial data defines the physical location of features within a coordinate system, typically expressed in terms of latitude and longitude. It provides precise positioning for elements like roads, rivers, or buildings.Attribute DataAttribute data complements spatial data by adding descriptive information about these features. For example, a road's spatial data includes its start and...

Area of Science:

  • Health Services Research
  • Spatial Epidemiology
  • Public Policy Analysis

Background:

  • Geographic Information Systems (GIS) are valuable for evaluating location-dependent policies.
  • Nursing workforce distribution is a critical local issue, with shortages posing significant governmental concerns.
  • Missouri implemented a nurse recruitment policy in 1991 targeting Health Professional Shortage Areas (HPSA).

Purpose of the Study:

  • To evaluate the effectiveness of Missouri's nurse recruitment and retention policy.
  • To determine if the policy reduced disparities in nurse-to-population ratios in HPSA-designated counties.
  • To assess the utility of GIS and spatial statistics in policy evaluation.

Main Methods:

  • Utilized Geographic Information Systems (GIS) for data visualization.
  • Employed spatial and classical statistical analyses to compare HPSA and non-HPSA counties.
  • Examined nurse-to-population ratios over multiple time periods following policy implementation.

Main Results:

  • Statistical and GIS analyses did not show a consistent decrease in group differences between HPSA and non-HPSA counties over time.
  • Significant changes in nurse-to-population ratios were observed in HPSA counties during specific periods (1993-1995 and 1999-2001).
  • The observed trends suggest the policy may not be effectively addressing nursing shortages in designated areas.

Conclusions:

  • Current definitions of underserved areas may not accurately identify regions with critical nursing shortages.
  • The implemented nurse recruitment policy may not be achieving its intended goals of reducing disparities.
  • GIS and spatial statistics offer valuable insights for evaluating public health policies.
