Applications of geographical information system and spatial analysis in Indian health research: a systematic review
Published in Social Sciences and Sustainability
Background
Health is a fundamental right intricately linked to geographical factors, as evidenced in the health geography literature. The application of geographical information systems (GISs) plays a pivotal role in mapping diseases and evaluating healthcare accessibility and is acknowledged by the World Health Organisation as a solution for enhancing health system resilience and achieving universal health coverage. This study focuses on the geographical perspectives to provide insights into the evolving role of GIS in addressing challenges and shaping healthcare strategies in health research within India. The primary objective was to analyse the utilisation of GISs in health studies specifically on three thematic areas: disease surveillance, health risk assessment, and healthcare access.
Methods
The databases were searched using sixteen keywords for peer-reviewed articles published during 2000–2022. A systematic literature survey was conducted, drawing from peer-reviewed literature available in the PubMed, Web of Science and Scopus databases. Out of 162 search results, 58 articles were selected for review after three rounds of eliminations based on the predefined specific criteria. A systematic literature review was conducted following PRISMA guidelines addressing two research questions.
Results
This review reveals the extensive use of GIS in health studies since its inception, with particular prominence as a decision-making tool in the aftermath of the COVID-19 outbreak. The analysis of scientific articles focused on disease surveillance, risk assessment, and healthcare access in the Indian context demonstrates the effectiveness of GIS in managing and planning healthcare resources and services. GIS has proven to be an indispensable instrument for understanding spatial patterns in disease and optimising health interventions.
Conclusion
This systematic review underscores the critical role of GIS in health research, particularly in the Indian context. The versatile applications of GIS in disease surveillance, risk assessment, and healthcare access highlight its effectiveness as a tool for managing and planning healthcare strategies, contributing to a more resilient and accessible healthcare system in India and beyond. xxx

Patients' knowledge of the indications for their medications
BMC Health Services Research is calling for submissions to our Collection on Patients' knowledge of the indications for their medications.
Understanding the indications for prescribed medications is crucial for patient safety and effective healthcare delivery. Many patients lack adequate knowledge about their medications, which can lead to non-adherence, adverse drug reactions, and suboptimal health outcomes. This Collection invites research that examines the extent of patients' medication knowledge, the factors influencing their understanding, and the implications for healthcare practice. By exploring these aspects, we aim to illuminate the gaps in medication literacy and the importance of patient engagement in their treatment regimens.
Enhancing patients' knowledge of their medications is vital for fostering informed decision-making and promoting adherence to treatment plans. Recent advances in medication counseling, patient education programs, and digital health technologies have shown promise in improving medication awareness. These interventions not only empower patients but also support healthcare providers in delivering personalized care. By fostering a culture of medication literacy, healthcare systems can enhance patient outcomes and reduce the burden of medication-related issues.
Topics for submission:
Assessing medication literacy in diverse populations
Barriers and facilitators to understanding medication indications
Impact of patient education and other related interventions on medication adherence
Tools, interventions and strategies for enhancing patient medication knowledge
Understand how, why for whom and under what circumstances interventions to enhance medication knowledge work or not
This Collection supports and amplifies research related to SDG 3 (Good Health and Well-being).
All manuscripts submitted to this journal, including those submitted to collections and special issues, are assessed in line with our editorial policies and the journal’s peer review process. Reviewers and editors are required to declare competing interests and can be excluded from the peer review process if a competing interest exists.

Promise, perception, and practice: workforce capability and technology integration in healthcare
BMC Health Services Research invites submissions on how health workforce professionals interact with, adopt, and shape the implementation of digital health technologies, artificial intelligence (AI), and modern electronic health record (EHR) systems. Whether these technologies deliver value depends not only on the technical specifications but also on how they are implemented, governed, evaluated, and continuously refined within the organizations and workforces in which they operate. Health systems worldwide are committing to technology portfolios at a pace that consistently outstrips the evidence base needed to guide them, leaving technology program leaders without the knowledge they need to make sound investment and deployment decisions. We particularly welcome work that bridges implementation science, clinical informatics, and health services research to generate evidence actionable for health systems managing growing technology portfolios.
Topics of interest include, but are not limited to:
- Adoption and sustained use: digital literacy, training, and effective human–AI collaboration
- Front-line feedback as a signal for monitoring and improving technology performance
- Case studies of AI tools (clinical systems, ambient documentation, EHRs, decision support) with focus on long-term value and sustainment
- Governance, evaluation frameworks, and learning health system models for continuous assessment
- Impacts on care quality, clinician well-being, efficiency, and costs, including unintended effects (e.g., workflow disruption, alert fatigue)
- Ethical, equity, and policy considerations, including evolving AI governance
- Innovative measurement using EHR logs, administrative data, and observational methods
- Development of standardized evaluation frameworks applicable across technologies and settings
We welcome submissions across all article types accepted by BMC Health Services Research, including research articles, systematic reviews, study protocols, database and software articles.
