Research and Publications at Daradia

Introduction

Daradia: The Pain Clinic, New Town, Kolkata, combines clinical pain care with physician education and academic work. This page brings together selected publications, books and research resources associated with its founder and faculty, with direct links to the original sources.

Established in 2008, Daradia supports enquiry into pain assessment, treatment selection, image-guided procedures and clinical education. Our academic aim is to help clinicians examine evidence critically and connect research findings with responsible patient care.

Our approach to pain medicine research

Clinical research begins with a clear question. A proposed technique, an observational study, a narrative review and a randomised trial answer different questions and offer different levels of evidence. We encourage readers to examine each publication’s design, population, outcomes and limitations rather than treating publication alone as proof of treatment effectiveness.

Academic interests include clinical assessment, musculoskeletal ultrasound, interventional pain medicine, sacroiliac and spinal pain, psychiatric screening in pain practice, Pain Biologics and medical education. Individual projects and their findings should be assessed through their published reports.

The Daradia Protocol

The Daradia Protocol is a proposed structured pathway for psychiatric screening and initial management in interventional pain practice. It is described in a 2026 narrative review published in the Korean Journal of Pain.

The paper discusses a pragmatic 10-minute stepped-care approach using Green, Amber and Red categories to support procedural decision-making and referral urgency. The complete pathway requires prospective validation; publication of the review does not establish that the protocol itself is a validated prediction tool.

Publication: Das G, Nayak A, Pai AP, Das S. Psychiatric screening and initial management in interventional pain practice: a narrative review and the Daradia Protocol. Korean Journal of Pain. Published online September 18, 2026. DOI: 10.3344/kjp.26097. PMID: 42754825.

Implementation resources

The Daradia Protocol implementation toolkit provides supporting resources for clinicians exploring the pathway. A separately hosted toolkit record is available through Zenodo DOI 10.5281/zenodo.22872502. A repository resource is distinct from a peer-reviewed journal article.

Selected peer reviewed publications

The following examples include work by Daradia-affiliated authors and earlier research by the founder. They are a selected bibliography rather than a count of all institutional publications. Historical author affiliations remain those reported in the original papers.

Cryoneurolysis for sacroiliac joint pain

Sahoo RK, Das G, Pathak L, Dutta D, Roy C, Bhatia A. Cryoneurolysis of Innervation to Sacroiliac Joints: Technical Description and Initial Results—A Case Series. A&A Practice. 2021;15(4):e01427. DOI: 10.1213/XAA.0000000000001427.

This five-patient case series describes a technique and initial clinical observations. It provides preliminary evidence and does not establish comparative effectiveness.

Earlier research on ozone nucleolysis

Das G, Ray S, Ishwarari S, Roy M, Ghosh P. Ozone nucleolysis for management of pain and disability in prolapsed lumber intervertebral disc. A prospective cohort study. Interventional Neuroradiology. 2009;15(3):330–334. DOI: 10.1177/159101990901500311.

This earlier study by the founder was conducted at Charnock Hospital, Kolkata. It reports outcomes from an uncontrolled prospective cohort; its design limits conclusions about comparative treatment benefit.

Academic journal and foundation activities

The Daradia Pain Foundation supports academic and educational work in pain medicine. Related scholarly activity includes the Journal on Musculoskeletal Ultrasound and Pain Medicine, published by Wolters Kluwer–Medknow.

Visit the journal’s publisher homepage for articles, issues and submission information. The journal lists print ISSN 2950-4376 and online ISSN 2950-4384.

Peer-reviewed journal articles, conference abstracts, educational uploads and repository materials serve different purposes. They should be identified accurately when reporting academic output.

Research ethics and integrity

Responsible research requires appropriate ethics review, informed consent or an authorised waiver where applicable, protection of identifiable patient information and transparent reporting of funding and conflicts of interest.

For any proposed project involving patients or clinical data, the applicable institutional and regulatory requirements should be established before recruitment or data access. Ethics approval, trial registration where required and consent arrangements belong to the individual study.

Publication should describe methods and limitations clearly. Negative findings, uncertainty and methodological weaknesses are relevant parts of the evidence.

Research education for doctors

Daradia encourages doctors and fellows to develop skills in framing research questions, interpreting studies and preparing scientific writing. Educational work can include critical appraisal, case discussions and manuscript development.

Explore the basic online fellowship and advanced pain medicine course for current programme information. Learning activities and assessment requirements vary by programme.

Conferences and scientific exchange

ICRAPAIN — International Conference on Recent Advances in Pain provides opportunities for scientific presentations, discussion and academic exchange. Daradia’s cadaveric workshops provide focused anatomical and procedural education.

Conference presentation and workshop participation are distinct from publication in a peer-reviewed journal.

Research collaboration enquiries

Clinicians, researchers and institutions interested in discussing a research proposal or academic collaboration may contact Daradia. Please include the research question, proposed design, participating institutions and expected role of each collaborator. Do not send identifiable patient information in an initial enquiry.
