Issues And Trends In Healthcare Delivery System

5.6K
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...

Nursing Clinical Information System (NCIS)
A Nursing Clinical Information System (NCIS) is a specialized type of healthcare information system tailored to meet the unique needs of nursing practice. It incorporates the principles of nursing informatics to streamline information management and improve the quality of care delivery.
Critical attributes of NCIS include:

Ethical Standards I01:25

Ethical Standards I

774
The American Nurses Association (ANA) created and implemented the first nationally accepted Code of Ethics for Nurses with Interpretive Statements. The Code of Ethics is a living document regularly updated by the ANA and establishes an ethical standard that is non-negotiable for nurses in all roles and settings.
The Code of Ethics provisions outline the nurse's duty to the patient, the healthcare team, the profession, and society. The Code's fundamental principles include advocacy,...

Pharmacovigilance01:19

Pharmacovigilance

773
Post-marketing surveillance is a critical component of pharmaceutical regulation, often uncovering unanticipated adverse drug reactions (ADRs) once a drug is widely used over an extended period.
This process, termed pharmacovigilance, aims to detect, evaluate, and minimize harmful effects related to medication use. The data collection for pharmacovigilance depends on spontaneous reporting systems, where healthcare professionals or patients voluntarily report suspected ADRs.
In some cases, there...

Drug Control Governance: Regulatory Bodies and Their Impact01:03

Drug Control Governance: Regulatory Bodies and Their Impact

141
Drug control governance involves the oversight and regulation of pharmaceuticals to ensure their safety and efficacy while preventing illegal drug use and trafficking. Regulatory bodies, including the US Food and Drug Administration (FDA) and the European Union's European Medicines Agency (EMA), play a central role in this process. These agencies evaluate the safety and efficacy of drugs before they can be marketed. They fund clinical trials and assess the benefits and risks associated with...

Drug Distribution: Volume of Distribution01:25

Drug Distribution: Volume of Distribution

4.5K
The volume of distribution refers to the theoretical volume necessary to contain the entire amount of an administered drug at the same concentration observed in the blood plasma. The body's intracellular fluid compartment, which makes up two-thirds of the total body water, is contrasted with the extracellular fluid compartment—comprising plasma and interstitial fluid—that accounts for one-third. The volume of distribution can vary depending on the characteristics of the drug.

Area of Science:

  • Supply Chain Management
  • Blockchain Technology
  • Information Security

Background:

  • Traditional pharmaceutical supply chain management (PSCM) systems struggle with transparency and trust.
  • Existing online pharma systems face implementation challenges.
  • Key security goals for supply chain management (SCM) include authentication, confidentiality, data provenance, and auditability.

Purpose of the Study:

  • To propose and evaluate a novel blockchain-based solution for pharmaceutical supply chain management (BPSCM).
  • To enhance security, transparency, and trust among stakeholders in the pharmaceutical supply chain.
  • To address the limitations of traditional PSCM systems.

Main Methods:

  • Implementation of a three-phase BPSCM: registration, product circulation, and secure payment.
  • Utilizing hashed private keys and Edwards-curve digital signature algorithm (EdDSA) for stakeholder registration.
  • Development of smart contracts with cryptographic operators for secure transactions and data provenance during product circulation.

Main Results:

  • The BPSCM framework effectively mitigates impersonation and collusion attacks.
  • Security analysis confirms the robustness of the proposed solution.
  • Performance evaluation shows favorable metrics in gas consumption, throughput, latency, and computational cost compared to standard PSCM frameworks.

Conclusions:

  • The proposed BPSCM offers a secure and efficient alternative to traditional pharmaceutical supply chain systems.
  • Blockchain technology can significantly improve transparency, trust, and security in pharmaceutical logistics.
  • The BPSCM framework demonstrates practical viability and effectiveness for real-world application.
