Esmaeilzadeh and Sambasivan identified patient characteristics in relation to Health Information Exchanges.
- Gender: The authors find conflicting results for the effects of gender on either direct use of a Health Information Exchange (HIE) or accessing physicians who use HIE’s.
- Age: The authors cite research in which under 40’s saw Electronic Health Records (EHR) as improving privacy. Security was perceived as a more important factor for those between the ages of 40 and 64.
- Income: Higher income was associated with a more favourable attitude towards the use of HIE’s.
- Ethnicity: Ethnic minorities had greater concern about sharing information via HIE’s in two of the quoted studies
- Chronic disease: Patients with chronic diseases were more like to support the use of HIE’s. This was in part due to the perception that it would improve communication between healthcare providers.
Esmaeilzadeh and Sambasivan identified several perceived benefits of a Health Information Exchange in their paper. Perceived benefits may be different from actual benefits but are nevertheless valuable in the discussion of Health Information Exchanges. The identified perceived benefits from the literature review were
- Improved communication between health professionals
- Completeness of medical records
- Accuracy of medical records
- Improved safety of healthcare
- Improved quality of healthcare
- Tracking chronic diseases
- Early detection of infectious diseases
- Convenience for patients
- Expedited care
- Reduced healthcare bill
- Improved privacy of medical records
- Improved security
What were the main findings in the Esmaeilzadeh and Sambasivan paper?
Esmaeilzadeh and Sambasivan have published a paper on Health Information Exchanges, ‘Patients’ support for health information exchange: a literature review and classification of key factors‘.
They identified seven key themes from the literature
- Perceived benefits
- Perceived concerns
- Patient characteristics
- Level of patient participation in HIE
- Types of health information to be exchanged
- Types of recipients
- Patient preferences regarding consent
Patient records are central to the delivery of healthcare and serve a number of functions including the recording of clinical assessments and interventions. Aggregated data is also utilised at a local and national level to inform commissioning.
Electronic Patient Records
The digitisation of patient records offers a number of advantages over paper based records. These advantages include automated backup of records, reduced use of physical storage space (since paper based notes are switched to servers), off-site access to records using mobile devices and the potential to develop analytical clinical support tools which use computers to process clinical data to help improve clinical decisions. Not all healthcare services have electronic patient records but most providers are moving in this direction.
Getting Electronic Patient Records to Talk to Each Other
When patients move between healthcare providers – for instance between primary care and the hospital – they may find that one provider does not have information that the other provider has. There are many providers and many electronic paper record systems. For two systems to talk to each other they have to solve a number of problems. When these problems are solved a patient can move between providers and healthcare information can be accessed by the different providers. A key solution to this problem of health information gaps is the Health Information Exchange (HIE).
The Health Information Exchange
There are many definitions of what a Health Information Exchange is. (Hersh et al, 2015) define a HIE as follows:
‘Health information exchange (HIE), the electronic sharing of clinical information across the boundaries of health care organizations’
Whilst this definition is simple, the process of sharing clinical information between healthcare organisations is technically complex and encompasses a range of software, hardware and governance issues. The process of helping systems to talk to each other is helped by the development of standards. A set of standards is outlined in the NHS interoperability framework.
