Patient experiences of interprofessional collaboration and intersectoral communication in rare disease healthcare in Germany - a mixed-methods study

BACKGROUND

Rare diseases are often complex, chronic and many of them life-shortening. In Germany, healthcare for rare diseases is organized in expert centers for rare diseases. Most patients additionally have regional general practicioners and specialists for basic medical care. Thus, collaboration and information exchange between sectors is highly relevant. Our study focuses on the patient and caregiver perspective on intersectoral and interdisciplinary care between local healthcare professionals (HCPs) and centers for rare diseases in Germany. The aims were (1) to investigate patients' and caregivers' general experience of healthcare, (2) to analyse patients' and caregivers' perception of collaboration and cooperation between local healthcare professionals and expert centers for rare diseases and (3) to investigate patients' and caregivers' satisfaction with healthcare in the expert centers for rare diseases.

RESULTS

In total 299 individuals of whom 176 were patients and 123 were caregivers to pediatric patients participated in a survey using a questionnaire comprising several instruments and constructs. Fifty participants were additionally interviewed using a semistructured guideline. Most patients reported to receive written information about their care, have a contact person for medical issues and experienced interdisciplinary exchange within the centers for rare diseases. Patients and caregivers in our sample were mainly satisfied with the healthcare in the centers for rare diseases. The qualitative interviews showed a rather mixed picture including experiences of uncoordinated care, low engagement and communication difficulties between professionals of different sectors. Patients reported several factors that influenced the organization and quality of healthcare e.g. engagement and health literacy in patients or engagement of HCPs.

CONCLUSIONS

Our findings indicate the high relevance of transferring affected patients to specialized care as fast as possible to provide best medical treatment and increase patient satisfaction. Intersectoral collaboration should exceed written information exchange and should unburden patients of being and feeling responsible for communication between sectors and specialists. Results indicate a lack of inclusion of psychosocial aspects in routine care, which suggests opportunities for necessary improvements.

Coding undiagnosed rare disease patients in health information systems: recommendations from the RD-CODE project

BACKGROUND

In European Union countries, any disease affecting less than 5 people in 10,000 is considered rare. As expertise is scarce and rare diseases (RD) are complex, RD patients can remain undiagnosed for many years. The period of searching for a diagnosis, called diagnostic delay, sometimes leads to a diagnostic dead end when the patient's disease is impossible to diagnose after undergoing all available investigations. In recent years, extensive efforts have been made to support the implementation of ORPHA nomenclature in health information systems (HIS) so as to allow RD coding. Until recently, the nomenclature only encompassed codes for specific RD. Persons suffering from a suspected RD who could not be diagnosed even after full investigation, could not be coded with ORPHAcodes. The recognition of the RD status is necessary for patients, even if they do not have a precise diagnosis. It can facilitate reimbursement of care, be socially and psychologically empowering, and grant them access to scientific advances.

RESULTS

The RD-CODE project aimed at making those patients identifiable in HIS in order to produce crucial epidemiological data. Undiagnosed patients were defined as patients for whom no clinically-known disorder could be confirmed by an expert center after all reasonable efforts to obtain a diagnosis according to the state-of-the-art and diagnostic capabilities available. Three recommendations for the coding of undiagnosed RD patients were produced by a multi-stakeholder panel of experts: 1/ Capture the diagnostic ascertainment for all rare disease cases; 2/ Use the newly created ORPHAcode (ORPHA:616874 "Rare disorder without a determined diagnosis after full investigation"), available in the Orphanet nomenclature: as the code is new, guidelines are essential to ensure its correct and homogeneous use for undiagnosed patients' identification in Europe and beyond; 3/ Use additional descriptors in registries.

CONCLUSIONS

The recommendations can now be implemented in HIS (electronic health records and/or registries) and could be a game-changer for patients, clinicians and researchers in the field, enabling assessment of the RD population, including undiagnosed patients, adaptation of policy measures including financing for care and research programs, and to improved access of undiagnosed patients to research programs.

Health care utilisation and education outcomes of children with rare diseases: a born in Bradford cohort study

The purpose of this study is to describe the burden of health care utilisation and early education outcomes of children with and without rare diseases. Using the Born in Bradford birth cohort and its linked routine health care and education data, we looked at cumulative primary care episodes, hospital admissions and medication prescriptions. We assessed education outcomes using Early Years Foundation Stage Profile and the National Curriculum Tests-Key Stage 1 results. Among analytical sample of 13,858, 1711 or 12.3% children were identified with a rare disease by an average age of 14 years. Children with rare diseases were twice more likely to be admitted to hospital compared to children without. Average length of stay was around 5 days in those with rare diseases group compared to less than 1 day in those without. The average number of primary care episodes was 45.4 in children with rare diseases and 28.2 visits in those without. These children were over three times more likely to be on multiple medications. Children with rare diseases had 30% higher risk of being below academic expectations at Foundation Year and, depending on subject, between 50 and 60% higher risks at KS1 tests.  Conclusions: Children with rare diseases are significantly more likely to have increased primary care episodes and to have more regular medications. They are likely to have more hospital admissions with a longer stay also. Educationally, they are at higher risk of failing to achieve expected standards in early-year settings. What is Known: • Existing studies of rare diseases have used cross sectional data to describe secondary care data. Previous research has not explored the impact of rare diseases on academic outcomes in children. What is New: • Using Born in Bradford birth cohort and its linked primary and secondary care data, this study provides the most comprehensive estimate of prevalence of rare diseases in any study to date. Children with rare diseases were not only significantly more likely to have contact with primary care and to be admitted to hospitals; they were also more like to be on more regular medications and had higher risk of not achieving expected standards in early-year education outcomes. • Our study is unusual in being able to access linked health and education data and reinforces the importance of adopting a whole system approach to children's health and wellbeing that recognises the close links between health and education.
