Issues And Trends In Healthcare Delivery System

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...

Area of Science:

Medical Imaging
Biomedical Engineering
Additive Manufacturing

Background:

Three-dimensional (3-D) printing, also known as additive manufacturing, has evolved significantly from its origins in creating visual prototypes.
It offers an alternative to traditional subtractive manufacturing methods, providing versatile applications across various industries, including medicine.

Purpose of the Study:

To review the fundamental principles of 3-D printing.
To explore the future trajectory and integration of 3-D printing within the field of medical imaging.

Main Methods:

A comprehensive literature search was performed using major academic databases: EBSCO, JSTOR, ProQuest, and Google Scholar.
Preference was given to recent publications, with older relevant articles included to provide historical context.

Main Results:

3-D printing converts computer-aided designs into physical models, utilizing additive manufacturing techniques.
Its applications have expanded from simple prototyping to providing innovative solutions, particularly in medicine for anatomic modeling, teaching, and patient education.

Conclusions:

Radiology departments play a crucial role by supplying imaging data for 3-D fabrication of anatomical structures.
While initial costs may limit adoption in some healthcare settings, declining market competition is expected to reduce barriers, increasing accessibility of 3-D medical printing.
