Economic evaluation of clinical quality registries: a systematic review

Global data monitoring systems and early identification for kidney diseases

BACKGROUND

Data monitoring and surveillance systems are the cornerstone for governance and regulation, planning, and policy development for chronic disease care. Our study aims to evaluate health systems capacity for data monitoring and surveillance for kidney care.

METHODS

We leveraged data from the third iteration of the International Society of Nephrology Global Kidney Health Atlas (ISN-GKHA), an international survey of stakeholders (clinicians, policymakers and patient advocates) from 167 countries conducted between July and September 2022. ISN-GKHA contains data on availability and types of kidney registries, the spectrum of their coverage, as well as data on national policies for kidney disease identification.

RESULTS

Overall, 167 countries responded to the survey, representing 97.4% of the global population. Information systems in forms of registries for dialysis care were available in 63% (n = 102/162) of countries, followed by kidney transplant registries (58%; n = 94/162), and registries for non-dialysis chronic kidney disease (19%; n = 31/162) and acute kidney injury (9%; n = 14/162). Participation in dialysis registries was mandatory in 57% (n = 58) of countries; however, in more than half of countries in Africa (58%; n = 7), Eastern and Central Europe (67%; n = 10), and South Asia (100%; n = 2), participation was voluntary. The least-reported performance measures in dialysis registries were hospitalization (36%; n = 37) and quality of life (24%; n = 24).

CONCLUSIONS

The variability of health information systems and early identification systems for kidney disease across countries and world regions warrants a global framework for prioritizing the development of these systems.

Assessing Opportunities and Barriers to Improving the Secondary Use of Health Care Data at the National Level: Multicase Study in the Kingdom of Saudi Arabia and Estonia

BACKGROUND

Digitization shall improve the secondary use of health care data. The Government of the Kingdom of Saudi Arabia ordered a project to compile the National Master Plan for Health Data Analytics, while the Government of Estonia ordered a project to compile the Person-Centered Integrated Hospital Master Plan.

OBJECTIVE

This study aims to map these 2 distinct projects' problems, approaches, and outcomes to find the matching elements for reuse in similar cases.

METHODS

We assessed both health care systems' abilities for secondary use of health data by exploratory case studies with purposive sampling and data collection via semistructured interviews and documentation review. The collected content was analyzed qualitatively and coded according to a predefined framework. The analytical framework consisted of data purpose, flow, and sharing. The Estonian project used the Health Information Sharing Maturity Model from the Mitre Corporation as an additional analytical framework. The data collection and analysis in the Kingdom of Saudi Arabia took place in 2019 and covered health care facilities, public health institutions, and health care policy. The project in Estonia collected its inputs in 2020 and covered health care facilities, patient engagement, public health institutions, health care financing, health care policy, and health technology innovations.

RESULTS

In both cases, the assessments resulted in a set of recommendations focusing on the governance of health care data. In the Kingdom of Saudi Arabia, the health care system consists of multiple isolated sectors, and there is a need for an overarching body coordinating data sets, indicators, and reports at the national level. The National Master Plan of Health Data Analytics proposed a set of organizational agreements for proper stewardship. Despite Estonia's national Digital Health Platform, the requirements remain uncoordinated between various data consumers. We recommended reconfiguring the stewardship of the national health data to include multipurpose data use into the scope of interoperability standardization.

CONCLUSIONS

Proper data governance is the key to improving the secondary use of health data at the national level. The data flows from data providers to data consumers shall be coordinated by overarching stewardship structures and supported by interoperable data custodians.

Improvements in Quality, Safety and Costs Associated with Use of Implant Registries Within a Health System

BACKGROUND

Clinical quality registries (CQRs) are intended to enhance quality, safety, and cost reduction using real-world data for a self-improving health system. Starting in 2001, Kaiser Permanente established several medical device CQRs as a quality improvement initiative. This report examines the contributions of these CQRs on improvement in health outcomes, changes in clinical practice, and cost-effectiveness over the past 20 years.

METHODS

Eight implant registries were instituted with standardized collection from the electronic health record and other institutional data sources of patient characteristics, medical comorbidities, implant attributes, procedure details, surgical techniques, and outcomes (including complications, revisions, reoperations, hospital readmissions, and other utilization measures). A rigorous quality control system is in place to improve and maintain the quality of data. Data from the Implant Registries form the basis for multiple quality improvement and patient safety initiatives to minimize variation in care, promote clinical best practices, facilitate recalls, perform benchmarking, identify patients at risk, and construct reports about individual surgeons.

RESULTS

Following the inception of the Implant Registries, there was an observed (1) reduction in opioid utilization following orthopedic procedures, (2) reduction in use of bone morphogenic protein during lumbar fusion allowing for cost savings, (3) reduction in allograft for anterior cruciate ligament reconstruction and subsequent decrease in organizationwide revision rates, (4) cost savings through expansion of same-day discharge programs for joint arthroplasty, (5) increase in the use of cement fixation in the hemiarthroplasty treatment of hip fracture, and (6) organizationwide discontinuation of an endograft device associated with a higher risk for adverse outcomes following endovascular aortic aneurysm repair.

CONCLUSION

The use of Implant Registries within our health system, along with clinical leadership and organizational commitment to a learning health system, was associated with improved quality and safety outcomes and reduced costs. The exact mechanisms by which such registries affect health outcomes and costs require further study.

Development of an electronic burns register: Digitisation of routinely collected hospital data for global burns surveillance

INTRODUCTION

Burn registers provide important data that can track injury trends and evaluate services. Burn registers are concentrated in high-income countries, but most burn injuries occur in low- and middle-income countries where surveillance data are limited. Injury surveillance guidance recommends utilisation of existing routinely collected data where data quality is adequate, but there is a lack of guidance on how to achieve this. Our aim was to develop a rigorous and reproducible method to establish an electronic burn register from existing routinely collected data that can be implemented in low resource settings.

METHODS

Data quality of handwritten routinely collected records (register books) from a tertiary government hospital burn unit in Mysore, India was assessed prior to digitisation. Process mapping was conducted for burn patient presentations. Register and casualty records were compared to assess the case ascertainment rate. Register books from February 2016 to February 2022 were scanned and anonymised. Scans were quality checked and stored securely. An online data entry form was developed. All data underwent double verification.

RESULTS

Process mapping suggested data were reliable, and case ascertainment was 95%. 1930 presentations were recorded in the registers, representing 0.84% of hospital all-cause admissions. 388 pages were scanned with 4.4% requiring rescanning due to quality problems. Two-step verification estimated there to be errors remaining in 0.06% of fields following data entry.

CONCLUSION

We have described, using the example of a newly established electronic register in India, methods to assess the suitability and reliability of existing routinely collected data for surveillance purposes, to digitise handwritten data, and to quantify error during the digitisation process. The methods are likely to be of particular interest to burn units in countries with no active national burns register. We strongly recommend mobilisation of resources for digitisation of existing high quality routinely collected data as an important step towards developing burn surveillance systems in low resource settings.

Estimating the cost-effectiveness and return on investment of the Victorian Cardiac Outcomes Registry in Australia: a minimum threshold analysis

OBJECTIVES

We sought to establish the minimum level of clinical benefit attributable to the Victorian Cardiac Outcomes Registry (VCOR) for the registry to be cost-effective.

DESIGN

A modelled cost-effectiveness study of VCOR was conducted from the Australian healthcare system and societal perspectives.

SETTING

Observed deaths and costs attributed to coronary heart disease (CHD) over a 5-year period (2014-2018) were compared with deaths and costs arising from a hypothetical situation which assumed that VCOR did not exist. Data from the Australian Bureau of Statistics and published sources were used to construct a decision analytic life table model to simulate the follow-up of Victorians aged ≥25 years for 5 years, or until death. The assumed contribution of VCOR to the proportional change in CHD mortality trend observed over the study period was varied to quantify the minimum level of clinical benefits required for the registry to be cost-effective. The marginal costs of VCOR operation and years of life saved (YoLS) were estimated.

PRIMARY OUTCOME MEASURES

The return on investment (ROI) ratio and the incremental cost-effectiveness ratio (ICER).

RESULTS

The minimum proportional change in CHD mortality attributed to VCOR required for the registry to be considered cost-effective was 0.125%. Assuming this clinical benefit, a net return of $A4.30 for every dollar invested in VCOR was estimated (ROI ratio over 5 years: 4.3 (95% CI 3.6 to 5.0)). The ICER estimated for VCOR was $A49 616 (95% CI $A42 228 to $A59 608) per YoLS. Sensitivity analyses found that the model was sensitive to the time horizon assumed and the extent of registry contribution to CHD mortality trends.

CONCLUSIONS

VCOR is likely cost-effective and represents a sound investment for the Victorian healthcare system. Our evaluation highlights the value of clinical quality registries in Australia.

Gaining consensus on clinical quality outcomes for eating disorders: Framework for the development of an Australian national minimum dataset

OBJECTIVES

Eating disorders (EDs) are complex psychiatric illnesses requiring multidisciplinary care across both mental and medical healthcare settings. Currently, no nationally comprehensive, consistent, agreed on or mandated data set or data collection strategy exists for EDs in Australia: thus, little is known about the outcomes of care nor treatment pathways taken by individuals with EDs. InsideOut Institute was contracted by the Australian Government Department of Health to develop a minimum dataset (MDS) for the illness group with consideration given to data capture mechanisms and the scoping of a national registry.

DESIGN

A four-step modified Delphi methodology was used, including national consultations followed by three rounds of quantitative feedback by an expert panel.

SETTING

Due to social distancing protocols throughout the global SARS-CoV-2 pandemic, the study was conducted online using video conferencing (Zoom and Microsoft Teams) (Step 1), email communication and the REDCap secure web-based survey platform (Steps 2-4).

PARTICIPANTS

14 data management organisations, 5 state and territory government departments of health, 2 Aboriginal and Torres Strait Islander advising organisations and 28 stakeholders representing public and private health sectors across Australia participated in consultations. 123 ED experts (including lived experience) participated in the first quantitative round of the Delphi survey. Retention was high, with 80% of experts continuing to the second round and 73% to the third.

MAIN OUTCOME MEASURES

Items and categories endorsed by the expert panel (defined a priori as >85% rating an item or category 'very important' or 'imperative').

RESULTS

High consensus across dataset items and categories led to the stratification of an identified MDS. Medical status and quality of life were rated the most important outcomes to collect in an MDS. Other items meeting high levels of consensus included anxiety disorders, depression and suicidality; type of treatment being received; body mass index and recent weight change.

CONCLUSIONS

Understanding presentation to and outcomes from ED treatment is vital to drive improvements in healthcare delivery. A nationally agreed MDS has been defined to facilitate this understanding and support improvements.

Hip fracture registries in low- and middle-income countries: a scoping review

PURPOSE

The study aims to identify, describe, and organize the currently available evidence regarding hip fracture (HF) registries in low- and middle-income countries (LMICs).

METHODS

We conducted a scoping review adhering to PRISMA-ScR guidelines. We searched MEDLINE (PubMed), Google Scholar, Global Index Medicus, websites related to HF, and study references for eligible studies. Two reviewers independently performed the study selection and data extraction, including studies describing the use of individual patient records with the aim to improve the quality of care in older people with HF in LMICs.

RESULTS

A total of 222 abstracts were screened, 59 full-text articles were reviewed, and 10 studies regarding 3 registries were included in the analysis. Malaysia and Mexico implemented a HF registry in public hospitals whereas Argentina implemented a registry in the private setting. The Mexican registry, the most recent one, is the only one that publishes annual reports. There was significant variability in data fields between registries, particularly in functional evaluation and follow-up. The Ministry of Health finances the Malaysian registry, while Argentinian and Mexican registries founding was unclear.

CONCLUSION

The adoption of HF registries in LMICs is scarce. The few experiences show promising results but higher support is required to develop more registries. Long-term sustainability remains a challenge.

Development of a Bariatric Surgery Core Data Set for an International Registry

PURPOSE

Bariatric and metabolic surgery is an effective treatment for severe and complex obesity; however, robust long-term data comparing operations is lacking. Clinical registries complement clinical trials in contributing to this evidence base. Agreement on standard data for bariatric registries is needed to facilitate comparisons. This study developed a Core Registry Set (CRS) - core data to include in bariatric surgery registries globally.

MATERIALS AND METHODS

Relevant items were identified from a bariatric surgery research core outcome set, a registry data dictionary project, systematic literature searches, and a patient advisory group. This comprehensive list informed a questionnaire for a two-round Delphi survey with international health professionals. Participants rated each item's importance and received anonymized feedback in round 2. Using pre-defined criteria, items were then categorized for voting at a consensus meeting to agree the CRS.

RESULTS

Items identified from all sources were grouped into 97 questionnaire items. Professionals (n = 272) from 56 countries participated in the round 1 survey of which 45% responded to round 2. Twenty-four professionals from 13 countries participated in the consensus meeting. Twelve items were voted into the CRS including demographic and bariatric procedure information, effectiveness, and safety outcomes.

CONCLUSION

This CRS is the first step towards unifying bariatric surgery registries internationally. We recommend the CRS is included as a minimum dataset in all bariatric registries worldwide. Adoption of the CRS will enable meaningful international comparisons of bariatric operations. Future work will agree definitions and measures for the CRS including incorporating quality-of-life measures defined in a parallel project.

Economic Evaluation of the Community Benefit of the Australian Pregnancy Register of Antiseizure Medications

BACKGROUND AND OBJECTIVE

The Raoul Wallenberg Australian Pregnancy Register (APR) was established to collect, analyze, and publish data on the risks to babies exposed to antiseizure medications (ASMs) and to facilitate quality improvements in management care over time. It is one of the seveal prospective observational pregnancy registers of ASMs that has been established around the world. Although the APR and other registries have contributed to knowledge gain that has been applied to decrease adverse pregnancy outcomes, their cost-effectiveness remains unknown. Here, we aimed to evaluate the economic impacts of the APR from both societal and health care system perspectives.

METHODS

Using decision analytic modeling, we estimated the effectiveness (prevention of adverse pregnancy outcomes) and costs (costs of adverse pregnancy outcomes and the register itself) of the APR over a 20-year time horizon (2000-2019). The comparator was set as the adverse pregnancy outcomes collected by the APR between 1998 and 2002 (i.e., no APR derived improvements in care). In the scenario analysis, we conservatively assumed a 2.5% and 5% contribution of the APR to the savings in health care and societal costs. Adverse pregnancy outcomes included stillbirth, birth defects, and induced abortion. All cost data were derived from published sources. Health and economic outcomes were extrapolated to the total target Australian epilepsy population. The primary outcomes of interest were the return of investment (ROI) for the APR and incremental cost-effectiveness ratio (ICER) for cost per adverse outcome avoided.

RESULTS

Over the 20-year time horizon, the ROI from the APR from a societal perspective was Australian dollars (AUD) 2,250 (i.e., every dollar spent on the program resulted in a return of AUD2,250). Over this time, it was estimated that 9,609 adverse pregnancy outcomes were avoided, and health care and societal costs were reduced by AUD 191 million and AUD 9.0 billion, respectively. Hence, from a health economic point of view, the APR was dominant, providing cost saving ICERs from both perspectives.

DISCUSSION

Following its inception 20+ years ago, the APR has represented excellent value for investment for Australia, being also health-saving and cost saving from a societal and a health care perspective. With the growing number of marketed ASMs, the APR is expected to continue to have a major impact in the foreseeable future.

Establishing Self-Harm Registers: The Role of Process Mapping to Improve Quality of Surveillance Data Globally

Self-harm registers (SHRs) are an essential means of monitoring rates of self-harm and evaluating preventative interventions, but few SHRs exist in countries with the highest burden of suicides and self-harm. Current international guidance on establishing SHRs recommends data collection from emergency departments, but this does not adequately consider differences in the provision of emergency care globally. We aim to demonstrate that process mapping can be used prior to the implementation of an SHR to understand differing hospital systems. This information can be used to determine the method by which patients meeting the SHR inclusion criteria can be most reliably identified, and how to mitigate hospital processes that may introduce selection bias into these data. We illustrate this by sharing in detail the experiences from a government hospital and non-profit hospital in south India. We followed a five-phase process mapping approach developed for healthcare settings during 2019-2020. Emergency care provided in the government hospital was accessed through casualty department triage. The non-profit hospital had an emergency department. Both hospitals had open access outpatient departments. SHR inclusion criteria overlapped with conditions requiring Indian medicolegal registration. Medicolegal registers are the most likely single point to record patients meeting the SHR inclusion criteria from multiple emergency care areas in India (e.g., emergency department/casualty, outpatients, other hospital areas), but should be cross-checked against registers of presentations to the emergency department/casualty to capture less-sick patients and misclassified cases. Process mapping is an easily reproducible method that can be used prior to the implementation of an SHR to understand differing hospital systems. This information is pivotal to choosing which hospital record systems should be used for identifying patients and to proactively reduce bias in SHR data. The method is equally applicable in low-, middle- and high-income countries.

Mesh versus non-mesh repair of groin hernias: a rapid review

BACKGROUND

Mesh is frequently utilized intraoperatively for the repair of groin hernias. However, patients may request non-mesh hernia repairs owing to adverse events reported in other mesh procedures. To inform surgical safety, this study aimed to compare postoperative complications between mesh and non-mesh groin hernia repairs and identify other operative and patient-related risk factors associated with poor postoperative outcomes.

METHODS

Ovid MEDLINE and grey literature were searched to 9 June 2021 for studies comparing mesh to non-mesh techniques for primary groin hernia repair. Outcomes of interest were postoperative complications, recurrence of hernia, pain and risk factors associated with poorer surgical outcomes. Methodological quality was appraised using the AMSTAR 2 tool.

RESULTS

The systematic search returned 4268 results, which included seven systematic reviews and five registry analyses. Mesh repair techniques resulted in lower hernia recurrence rates, with no difference in chronic pain, seroma, haematoma or wound infection, compared to non-mesh techniques. Risk factors associated with increased risk of hernia recurrence were increased body mass index (BMI), positive smoking status and direct hernia. These were independent of surgical technique. Patients under 40 years of age were at increased risk of postoperative pain.

CONCLUSIONS

Surgical repair of primary groin hernias using mesh achieves lower recurrence rates, with no difference in safety outcomes, compared with non-mesh repairs. Additional risk factors associated with increased recurrence include increased BMI, history of smoking and hernia subtype.

The role of Australian clinical quality registries in pregnancy care: A scoping review

BACKGROUND

Pregnancy represents a time of increased morbidity and mortality for women and their infants. Clinical quality registries (CQRs) collect, analyse and report key healthcare quality indicators for patient cohorts to improve patient care. There are limited data regarding existing CQRs in pregnancy. This scoping review aimed to: (1) identify Australian CQRs specific to pregnancy care and describe their general characteristics; and (2) outline their aims and measured outcomes METHODS: The scoping review was undertaken according to Joanna Briggs Institute guidelines. CQRs were identified using a systematic approach from publications (Ovid MEDLINE, PubMed, Google Scholar), peer consultation, the Australian register of clinical registries and web searches. Details surrounding general characteristics, aims and outcomes were collated.

RESULTS

We identified two primary sources of information about pregnancy care. (1) Six CQRs are specific to pregnancy (Australia and New Zealand twin-twin transfusion syndrome registry, Australian Pregnancy Register for women with epilepsy and those taking anti-epileptic drugs, National Register of Antipsychotic Medication in Pregnancy, Australasian Maternity Outcomes Surveillance System, Neonatal Alloimmune Thrombocytopaenia Registry and the Diabetes in Pregnancy clinical register). (2) Fourteen observational cohort studies were facilitated by non-pregnancy-specific CQRs where a subsection of patients underwent pregnancy.

CONCLUSIONS

Australian CQRs currently report varied information regarding some selected conditions during pregnancy and offer therapeutic and epidemiological insight into their care. Further research into their effectiveness is warranted. We note the lack of a CQR spanning the common problems of pregnancy in general, where significant health, service and economic gains are possible.

Clinical quality registries: urgent reform is required to enable best practice and best care

Clinical quality registries (CQRs) systematically collect data on pre-agreed markers of quality of care for a given procedure, that can be reliably and reproducibly defined and collected across multiple sites. Data is then risk adjusted, and comparisons may be used to benchmark performance. These data then inform quality improvement initiatives. CQRs require an overarching independent governance structure and surety of funding. CQRs rely upon whole of population enrolment to minimize the risk of selection bias, and often rely on the secondary use of sensitive health information, meaning that the processes for ethical review and consent to participation are different to clinical trials. Despite several local examples of CQR improving practice in Australia and Aotearoa New Zealand, providing substantial cost-benefit to the community, there remain significant barriers to CQR implementation and functions. These include the difficulty of accurate data capture, lack of a fit for purpose ethical review system, the constraints of existing Qualified Privilege legislations and the need for protected funding. Whilst the Australian Government has released a 10-year strategy for CQR reform, and the Aotearoa New Zealand Government has included registries in the planned Health New Zealand reforms for the public sector, we believe more urgent implementation of strategies to overcome these barriers is needed if CQRs are to have the impact on quality of care our Communities deserve.

[Quality in sports orthopedics and traumatology: more than just return to play]

Quality assessment is gaining in importance in sports orthopedics and traumatology. Structural, process and results quality are differentiated as central quality dimensions in healthcare. Structural quality is understood to mean the capabilities of the institution involved in patient care with its human and material resources. Structural quality can be documented using institutional certificates (e.g. knee center of the German Knee Society, DKG) or personal certificates (e.g. DKG knee surgeon). Process quality evaluates all medical, nursing and administrative activities that are involved in the care process. The outcome quality describes changes in the patient's state of health that can be attributed to medical, nursing and physiotherapeutic measures. The measurement of the outcome quality can be broken down into objective and subjective parameters. In terms of subjective parameters patient reported outcome measures (PROM) play a major role. Another quality initiative in recent years can be seen in healthcare research. In this context medical registers play a role in which long-term healthcare data are prospectively collated and involves data on the quality of the process and outcome. The outcome quality is also the focus of value-based reimbursement systems.

Reoperative Cervical Endocrine Surgery: Appropriate Valuation for the Time and Effort?

BACKGROUND

Controversies currently exist regarding the best way to appropriately quantify complexity and to benchmark reimbursement for surgeons. This study aims to analyze surgeon reimbursement in primary and redo-thyroidectomy and parathyroidectomy using operative time as a surrogate for complexity.

METHODS

A retrospective analysis using the National Surgical Quality Improvement Program database was performed to identify patients who underwent primary and redo-thyroidectomy and parathyroidectomy. Calculations of median operative time work relative value units per minute and dollars per minute were compared between primary and redo procedures.

RESULTS

Thyroidectomy cases represented 53.5% (22,521 cases), and the other 46.5% (19,596 cases) were parathyroidectomy cases. The median dollars per minute in primary thyroidectomy was $4.97 and for redo-thyroidectomy was $8.12 (P < 0.0001). By the same token, dollars per minute were higher in the redo cases with $15.40 when compared with primary parathyroidectomy cases with $13.14 dollars per minute (P < 0.0001).

CONCLUSIONS

By Current Procedural Terminology codes, surgeons appear to be appropriately reimbursed for redo-thyroid and parathyroid procedures indexed to first time parathyroidectomy based on the compensated operative time of these procedures calculated using a nationally representative sample.

NSQIP versus institutional morbidity and mortality conference: complementary complication reporting in pediatric spine fusion

PURPOSE

Other fields of medicine have demonstrated underreported surgical complication rates by institutional M&M compared to NSQIP. However, a study comparing surgical complication rates in the pediatric spine population, using an identical set of patients rather than nationally extrapolated, has not been performed.

METHODS

A single institution's ASC-NSQIP Pediatric spine fusion cases and its departmental team-reported M&M database for the same were reviewed for January 1, 2012 to December 31, 2018. Differences in surgical complication reporting between the two databases for the identical patient cohort were recorded.

RESULTS

NSQIP identified 50 pediatric spine fusion patients with complications out of 386 NSQIP-algorithm-sampled cases (13%). Of these complications, 23 were not reported in the M&M conference database (6% of NSQIP-sampled cases, 2.5% of all M&M cases). The most common under-reported complication categories include pneumonia (100% under-reported), clostridium difficile (100%), urinary tract infection (83%), and superficial wound disruption (67%). During the same 7 years, M&M covered 924 spine fusions and identified 162 complications. Of these 162 patients, 22 were included in the NSQIP sampling and were not reported as complications (6% of NSQIP sampled patients).

CONCLUSION

Recognizing complication rates is central to implement strategies for delivering better quality care. NSQIP data may serve as an important quality check for pediatric spine institutional M&M data, but both may not include all complications even within its sampled patients. In general, NSQIP's protocols identified more medical complications, while M&M has a surgical focus, benefits from the limitless follow-up, and involves timely departmental awareness of complications.

The Euro Heart Survey and EURObservational Research Programme (EORP) in atrial fibrillation registries: contribution to epidemiology, clinical management and therapy of atrial fibrillation patients over the last 20 years

Management of atrial fibrillation (AF) may be challenging in clinical practice. Given the complexity of AF patients and the continuous advances in AF clinical management, there is a need for standardized programmes aimed at collecting so-called 'real-world clinical practice data' regarding the epidemiology, diagnostic/therapeutic/management practices and assessing adherence to guidelines. Over the past 20 years, the number of registries and surveys based on real-world AF patients has been dramatically increased. In Europe, based on the Euro Heart Survey (EHS) and the EURObservational Research Programme (EORP), a large series of studies based on these prospective, observational, large-scale multicentre registries on AF have been published. This narrative review gives an overview of these two projects on AF led by the European Society of Cardiology, focusing mainly on the contribution that these studies have provided to AF management and patient outcomes. Both the EHS and the EORP registries have collected a large amount of data regarding contemporary clinical practice, and despite some limitations, mainly related to their observational nature, these registries have contributed to our knowledge and clinical management of AF patients.
