Show details33. Integrated patient information systems
33.1. Introduction
It is generally accepted that appropriate information sharing within departments in an organisation and between different organisations is of importance in supporting co-ordinated care for patients, improving patient experience and achieving greater efficiency and value from health delivery systems.
An integrated patient information system would allow authorised health and social care professionals to have access to the patient’s clinical information (for example, laboratory results, medications, allergies and clinical notes) from multiple providers. It could also allow the patient to view the record and where appropriate add any self-monitoring information. Many benefits and efficiencies can flow from information being recorded, at contact with health and care services, and shared securely between those providing care.
33.2. Review question: Do integrated patient information systems throughout the AME pathway (primary and secondary care) improve patient outcomes?
For full details see review protocol in Appendix A.

33.4. Economic evidence
Published literature
No relevant health economic studies were identified.
The economic article selection protocol and flow chart for the whole guideline can found in the guideline’s Appendix 41A and Appendix 41B.
In the absence of health economic evidence, unit costs were presented to the guideline committee – see Chapter 41 Appendix I.
33.5. Evidence statements
Clinical
One study comprising 1616 participants evaluated integrated patient information system for improving outcomes in secondary care in adults and young people at risk of an AME, or with a suspected or confirmed AME. The evidence for integrated patient information systems suggested there was no difference for repeat visits to the ED within 28 days (moderate quality) or duplication of diagnostic tests between ED and the family physician (very low). However, the evidence for integrated patient information systems suggested there was a possible increase of repeat visits to the ED within 14 days (low quality) and duplication of diagnostic tests in speciality consultations (low quality) compared to no integrated patient information systems.
Economic
No relevant economic evaluations were identified.
33.6. Recommendations and link to evidence

Research recommendations | RR14. What is the clinical and cost effectiveness of different methods for integrating patient information throughout the emergency medical care pathway? |
Relative values of different outcomes |
Mortality, avoidable adverse events (including missed or delayed treatments and missed or delayed investigations, prescribing errors − errors of omission or commission and medicines reconciliation), quality of life and patient and/or carer satisfaction were considered by the committee to be critical outcomes. Length of stay, ED admissions, unnecessary duplication of tests and staff satisfaction were considered to be important outcomes. |
Trade-off between benefits and harms |
There was evidence from 1 cross-over cluster randomised trial comparing integrated patient information systems with no integrated patient information systems. The evidence for integrated patient information systems suggested there was no difference for repeat visits to the ED within 28 days or duplication of diagnostic tests between ED and the family physician. However, the evidence for integrated patient information systems suggested there was a possible increase of repeat visits to the ED within 14 days and duplication of diagnostic tests in speciality consultations compared to no integrated patient information systems. No evidence was available for the outcomes mortality, avoidable adverse events (including missed or delayed treatments and missed or delayed investigations), prescribing errors (errors of omission or commission, medicines reconciliation), quality of life, patient and/or carer satisfaction, length of stay and staff satisfaction. The committee also noted that there was a lack of evidence identified on patient safety outcomes in this review. The committee were of the view that, given properly designed IT systems, information sharing between primary/secondary care and social care would be effective and should be beneficial for patients, particularly regarding prescription of medications and documenting allergies. However, the trials available did not demonstrate these effects. Personal experience of shared information systems by the committee indicated that they could be helpful in caring for patients, particularly those with multimorbidity. However, in view of the lack of evidence the committee considered that a research recommendation would be most appropriate in this area. It would be particularly helpful to understand what the optimum way to configure the system would be to deliver best use of limited resources. |
Trade-off between net effects and costs |
The committee discussed qualitatively the potential costs involved for an integrated information system. The committee considered there would be a significant upfront cost of these systems during development and during implementation as they would probably be used alongside the existing system. Additional long-term maintenance costs might be equivalent to existing systems, but data security and linkage across different platforms would probably increase costs. There would also be additional resource implications for performance upgrades, and ensuring that they remain fit for purpose. Given that the integration of systems could potentially provide benefits to a large number of patients over time, the upfront costs involved in the implementation would become relatively small when measured per person. The committee also considered the benefits to patients of the different providers having access to information about drug prescriptions and allergies; improvements in patient safety could well justify the implementation costs. The unit costs of tests and ED presentations were presented to the committee for them to consider the potential cost savings (Chapter 41 Appendix I). |
Quality of evidence | The quality of the evidence for the study comparing integrated patient information systems with no integrated patient information systems was graded from moderate to very low; this was mainly due to risk of bias, indirectness and imprecision. |
Other considerations |
The integration of information systems is essential to support shared care and to provide consistent patient centred care to individuals who may be mobile and have their care delivered in multiple facilities. Clinical care increasingly requires healthcare professionals to access patient record information that may be distributed across multiple sites, held in a variety formats. In hospitals, information technologies tend to combine different modules or subsystems, resulting in a best-of-breed approach. To integrate clinical information systems in a way that will improve communication and data use for healthcare delivery, research and management, many different issues must be addressed. To consistently combine data from heterogeneous sources takes a great deal of time and effort because the individual feeder systems usually differ in several aspects, such as functionality, presentation and data representation. It will be challenging to make electronic health records operable between sites with the preservation of clinical meaning. The committee noted that the effective sharing of information has been recognised to be fundamental in the care of patients and is in line with the additional Caldicott Principle5 published in April 2013 which states “the duty to share information can be as important as the duty to protect patient confidentiality”. Healthcare professional should have training into using the systems developed which also includes regular updates. The training should also outline the Caldicott Principles and demonstrate best practice in this aspect but also best practice in the efficient use of such systems. Patient consent for information sharing between sectors of health and social care would be required. Sometimes consent is implied, for example, when a patient is admitted to hospital, all relevant healthcare professionals who are caring for the patient should have access to that information; however, those who are not should not. When considering sharing large and important amounts of information about a patient, more formal consent will be required. Timely access to shared patient information would be particularly important when caring patients with cognitive impairment or in meeting a patient’s preferences in terms of end of life care. Systems are likely to change in the future as technology advances, offering greater functionalities and rapid access to the results of investigations, combined with clinical decision support. Current examples of integrated patient information systems are NHS Spine and Enhanced Summary Care Records. The committee was aware that, in several locations around the country, web- based integrated patient information systems between primary and secondary care are currently being set up. This research recommendation is intended to encourage parallel evaluation of local innovation. |

Guideline condition and its definition | AME. |
Objectives |
Patient records are not easily accessible by all health care professionals (HCP) involved in the care of a patient, particularly if they are working in separate organisations. Information about patients’ management, care provided and requirements is often lost during transfers of care. This can impair communication between HCPs and can lead to errors and unnecessary duplication all of which can lead to avoidable adverse events, delays and increase in HCP demand. A working definition of ‘integration’ is the management and delivery of health services so that clients receive a continuum of preventative and curative services, according to their need over time and across different health systems. IT or informatics integration involves sharing communication, data collection, storage, analysis and dissemination strategies. An integrated IT system throughout the AME pathway should improve patient care and thus outcomes. |
