Swedish Heart-Lung Registry The Swedish Heart-Lung Registry is a national clinical registry for cardiac and pulmonary procedures in Sweden that systematically records patient-level data to monitor care quality, outcomes, and research. It interfaces with multiple Swedish healthcare institutions and international partners to support benchmarking, guideline implementation, and comparative effectiveness studies. The registry operates within Sweden’s health data infrastructure and collaborates with academic centers, specialist societies, and national agencies.

History

The registry was initiated during a period of expanding clinical registries in Scandinavia influenced by initiatives from Karolinska Institutet, Uppsala University, and early quality registries in Norway and Denmark. Early developmental work involved cardiothoracic units at Sahlgrenska University Hospital, Lund University Hospital, and Umeå University Hospital and drew on methods from registries such as the Swedish Rheumatology Quality Register and national efforts by the Swedish Association of Local Authorities and Regions. Key milestones included digitalization of data fields, linkage to the Swedish National Board of Health and Welfare, and adoption of standardized definitions promoted by the European Society of Cardiology and the European Respiratory Society.

Purpose and Scope

The registry’s primary purpose is quality improvement and outcome surveillance for invasive and non-invasive cardiothoracic interventions performed across Sweden, aligning with standards from World Health Organization initiatives and recommendations by the World Heart Federation. Scope encompasses adult and pediatric services at tertiary centers like Skåne University Hospital and regional units including Örebro University Hospital, covering procedures associated with institutions such as Karolinska University Hospital and professional bodies like the Swedish Society of Cardiology and the Swedish Society of Thoracic Surgery. It supports national quality indicators used by the National Board of Health and Welfare (Sweden) and benchmarking against registries maintained by British Heart Foundation-affiliated centers and the American Heart Association datasets.

Data Collection and Variables

Data collection uses standardized forms developed with input from clinical leads at Karolinska Institutet, Lund University, and specialty groups from Linköping University. Variables include patient demographics linked to the Swedish Tax Agency population registers, clinical presentation codes harmonized with the World Health Organization classifications, procedural descriptors used by the European Association for Cardio-Thoracic Surgery, device identifiers referenced in registries like the US Food and Drug Administration device databases, and outcome metrics aligned with the International Consortium for Health Outcomes Measurement. The dataset permits linkage with mortality records from the Swedish Cause of Death Register, prescription data from the Swedish Prescribed Drug Register, and hospitalization data from regional health information systems at centers such as Norrlands Universitetssjukhus.

Governance and Quality Control

Governance is provided through a steering committee with representatives from academic hospitals including Karolinska University Hospital, national agencies such as the Swedish National Board of Health and Welfare, and professional societies like the Swedish Society of Cardiology and Swedish Society of Thoracic Surgery. Data protection and ethical oversight align with legislation influenced by the European Union data protection frameworks and guidance from the Swedish Data Protection Authority. Quality control mechanisms include automated validation routines, audits modeled after methodologies from the National Quality Forum and performance feedback loops used by the NHS England registries, with periodic peer review by experts from universities including Uppsala University and Gothenburg University.

Research and Publications

The registry has enabled numerous observational studies, health services research projects, and registry-based randomized trials conducted by investigators at Karolinska Institutet, Lund University, and Umeå University. Published outputs compare procedural outcomes to international cohorts from the Society of Thoracic Surgeons databases, evaluate device performance in line with evidence cited by the European Medicines Agency, and inform guideline updates by the European Society of Cardiology and European Respiratory Society. Collaborative publications have appeared in journals influenced by editorial boards at institutions like Oxford University Press and publishers associated with Wiley and Elsevier.

Impact on Clinical Practice and Outcomes

Findings derived from the registry have informed practice changes at centers including Sahlgrenska University Hospital, Skåne University Hospital, and community hospitals, contributing to reduced complication rates, standardized care pathways, and adoption of evidence-based protocols akin to initiatives led by the American College of Cardiology. Outcomes data have been used by the National Board of Health and Welfare (Sweden) and regional health authorities to set performance targets and drive quality improvement programs comparable to those supported by the Institute for Healthcare Improvement. The registry’s linkage capacity has enabled long-term outcome surveillance, influencing decisions by device manufacturers and regulators such as the European Medicines Agency and contributing to translational research at institutes like Karolinska Institutet and Lund University.
