1.0 Introduction

The integration of blockchain technology into healthcare systems presents a transformative opportunity to enhance data security, privacy, and identity management. In Uganda, healthcare institutions grapple with challenges such as data breaches, unauthorized access, and inefficient patient information handling (Mukherjee et al., 2020). As health records become increasingly digitized, safeguarding patient data while ensuring accessibility for authorized providers has emerged as a critical priority. Conventional centralized systems are prone to cyber threats and unauthorized alterations, highlighting the need for decentralized, secure data management solutions (Zhang et al., 2017). This study investigates the potential of blockchain technology to strengthen patient data privacy and decentralized identity management in Uganda’s healthcare sector.

Blockchain operates as a decentralized, tamper-proof ledger that facilitates secure and transparent transactions across multiple nodes (Nakamoto, 2008). Unlike traditional health information systems that rely on centralized databases vulnerable to cyberattacks, blockchain employs cryptographic techniques to ensure data integrity and confidentiality (Jalali et al., 2019). Through decentralized identity management, patients gain greater control over their medical records, with access governed by smart contracts and cryptographic keys (Aziz & Tariq, 2021). Implementing blockchain-based solutions in Uganda could mitigate data vulnerabilities while improving information accessibility for healthcare providers.

This research conducts a scoping review to evaluate the feasibility, challenges, and potential impact of blockchain-based patient data privacy and decentralized identity management in Uganda’s healthcare system. By analyzing existing literature, pilot projects in comparable contexts, and policy implications, the study aims to demonstrate how blockchain can address persistent data security issues. Additionally, assessing the regulatory environment and technological barriers will help identify practical applications and limitations of blockchain in Uganda’s healthcare sector.

1.1 Background of the Study

The healthcare industry is undergoing digital transformation to bolster data security, patient privacy, and medical record management efficiency. In Uganda, ensuring the confidentiality and accessibility of patient data remains a major challenge. Traditional healthcare systems depend on centralized databases, which are susceptible to cyber threats, breaches, and unauthorized access (Mukherjee et al., 2020). Weak identity management systems exacerbate these problems, leading to medical identity theft, duplicate records, and inefficiencies in data handling. Blockchain technology offers a promising solution by providing a decentralized, immutable ledger that enhances data privacy and security (Zhang et al., 2017).

1.1.1 Historical Perspective

Historically, patient data management relied on paper-based systems, which posed difficulties in storage, retrieval, and security. Over time, electronic medical records (EMRs) were introduced to improve efficiency and accessibility (Kuo et al., 2017). However, centralized digital health systems remain vulnerable to cyber threats, unauthorized access, and data silos that hinder interoperability (Jalali et al., 2019). Blockchain, introduced in 2008 alongside Bitcoin, has gained traction in healthcare due to its security, transparency, and immutability (Nakamoto, 2008). Countries like Estonia and the U.S. have explored blockchain-based health record solutions, offering valuable insights for Uganda’s potential adoption (Aziz & Tariq, 2021).

1.1.2 Theoretical Perspective

This study is anchored in key theoretical frameworks supporting blockchain adoption in healthcare. Rogers’ Diffusion of Innovation Theory (2003) explains how new technologies like blockchain are adopted in sectors, progressing through stages of knowledge, persuasion, decision, implementation, and confirmation. Uganda’s adoption of blockchain for patient data privacy will depend on perceived benefits, complexity, compatibility, and trialability.

Decentralization Theory (Swan, 2015) posits that decentralized systems offer greater security, transparency, and autonomy than centralized models. Blockchain’s decentralized nature ensures trust and security, making it ideal for protecting sensitive health data. Additionally, the Technology Acceptance Model (TAM) (Davis, 1989) helps assess healthcare providers’ willingness to adopt blockchain-based identity systems, influenced by perceived ease of use and usefulness.

1.1.3 Conceptual Perspective

This study’s conceptual framework is rooted in blockchain technology, data privacy, and decentralized identity management principles. It views patient data management as crucial for healthcare delivery, requiring secure, transparent, and efficient systems. Blockchain is conceptualized as a transformative innovation that enhances security through cryptography and decentralization, mitigating risks of centralized data storage (Nakamoto, 2008).

In Uganda, patient data is often fragmented across centralized databases vulnerable to cyber threats (Mukherjee et al., 2020). Blockchain’s decentralized ledger, cryptographic hashing, smart contracts, and consensus mechanisms enable tamper-resistant health records (Aziz & Tariq, 2021).

Decentralized identity management empowers patients with self-sovereign identities, allowing secure access permissions for providers (Jalali et al., 2019). This approach enhances autonomy, reduces identity theft risks, and improves interoperability.

The study also examines blockchain adoption challenges in Uganda, including infrastructure gaps, regulatory uncertainties, and ethical concerns regarding data ownership (Kuo et al., 2017). By proposing a blockchain-based framework, the research bridges theoretical applications with practical implementation in Uganda’s digital health ecosystem.

1.1.4 Contextual Perspective

Uganda’s healthcare system comprises public and private institutions facing significant data management challenges. While digital health initiatives are advancing, issues such as poor infrastructure, weak cybersecurity, and limited interoperability persist (Mukherjee et al., 2020). Rural facilities often rely on paper records, hindering efficient data retrieval and continuity of care (Kuo et al., 2017). Blockchain could offer a secure, decentralized solution for patient records and identity verification.

However, adoption barriers include inadequate infrastructure, low digital literacy among healthcare workers, and regulatory gaps (Aziz & Tariq, 2021). Developing supportive policies and fostering collaboration among government, healthcare providers, and tech firms will be essential for successful integration.

In summary, blockchain-based solutions present a transformative opportunity for Uganda’s healthcare system by addressing data security, identity management, and interoperability. This study evaluates blockchain’s feasibility, benefits, and challenges, contributing to Africa’s digital health innovation discourse.

1.2 Statement of the Problem

The digitization of healthcare systems introduces both opportunities and challenges in managing patient data securely. In Uganda, centralized and fragmented data storage systems pose significant risks to data privacy and identity management (Mukherjee et al., 2020). Many institutions still use paper-based or centralized EMR systems, which are prone to breaches, unauthorized access, and data loss (Kuo et al., 2017). The lack of a unified digital infrastructure leads to inefficiencies, medical errors, duplicate records, and poor data sharing among providers (Zhang et al., 2017).

A critical issue is the absence of a robust identity management framework, resulting in multiple patient records across facilities and increasing risks of misidentification and medical identity theft (Jalali et al., 2019). Blockchain’s decentralized, immutable nature could address these challenges by improving security, patient autonomy, and interoperability (Aziz & Tariq, 2021).

Despite its potential, blockchain adoption in Uganda’s healthcare sector remains limited due to infrastructural deficits, low awareness among professionals, and unclear regulations (Mukherjee et al., 2020). Ethical and legal concerns, including data ownership and compliance with international standards, must also be resolved (Kuo et al., 2017).

This study explores blockchain’s feasibility in enhancing patient data privacy and decentralized identity management in Uganda, offering insights into overcoming implementation barriers.
