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...

Microorganisms in Medicine and Therapeutics

Microorganisms play a fundamental role in vaccine development, gene therapy, and therapeutic production. Their biological properties are harnessed to advance medicine and public health. Beyond immunization, microorganisms contribute to gut health, antibiotic synthesis, and genetic disease treatment.Live Attenuated and Inactivated VaccinesLive attenuated vaccines, such as the measles, mumps, and rubella (MMR) vaccine, utilize weakened forms of pathogens to closely resemble natural infections.

Area of Science:

Health Informatics
Computer Science
Supply Chain Management

Background:

Large-scale COVID-19 vaccine production since 2020 has resulted in significant waste due to overproduction and underutilization.
Current waste management systems lack transparency, traceability, accountability, trust, and security.
Addressing vaccine waste is critical for efficient healthcare resource allocation.

Purpose of the Study:

To propose a novel blockchain-based solution to mitigate waste in COVID-19 vaccine supply chains.
To enhance transparency, traceability, and accountability in vaccine management.
To reduce vaccine waste stemming from overproduction and underconsumption.

Main Methods:

A five-phase blockchain framework: registration, commitment, production/delivery, consumption, and waste assessment.
Implementation of smart contracts to govern the vaccine lifecycle and ensure accountability.
Utilizing decentralized storage (IPFS) for efficient data management and immutable ledger for security and provenance.

Main Results:

The proposed solution ensures security, traceability, and data provenance through smart contracts on an immutable ledger.
Security, cost, and scalability analyses demonstrate the solution's affordability, scalability, and robustness.
Demonstrated novelty and superiority compared to existing blockchain-based solutions.

Conclusions:

The blockchain-based system effectively addresses COVID-19 vaccine waste by improving lifecycle management.
The solution offers a secure, transparent, and accountable method for managing vaccine production and distribution.
Publicly available smart contract code facilitates adoption and further development.
