This paper introduces eight different services providing social prescribing in Wessex and describes our work to understand and evaluate the impact they are having, to support their development.

The first publication on howRu, describing why and how it was developed for routine use. It includes results from 2,750 people with long term conditions. The correlation of summary scores for howRu and the SF-12 health survey was high (r=0.81).

This describes the development and purposes of the howRwe patient experience measure. It includes a case study of a service improvement project at Oxford University Hospitals, showing statistically significant improvements in promptness and organisation aspects, after the change, with no change in clinical compassion or communication aspects.

This presents the results of a Dutch study which explored how well the howRu and howRwe surveys capture patients’ perceptions. Patients competed the surveys and were then interviewed by a review panel of GPs, who then completed the same surveys. The correlation between the patients and the review panel for howRu was CCC=0.80; for howRwe CCC=0.57. They concluded that howRu is suitable for use clinically at the individual patient level, but howRwe is not [NB howRwe is only used as an aggregate measure].

This compares the outcomes of hip and knee replacement surgery as measured by howRu (n=116) and EQ-5D (n=59,036), with both cohorts using the Oxford Hip and Knee scores as a common comparator. Outcome is the difference between the score prior to surgery and six months after surgery. The correlation of outcome between howRu and the Oxford scores was higher than that of EQ-5D (Hips howRu r=0.77, EQ-5D r=0.64; Knees howRu r=0.86, EQ-5D r=0.59).

This summarises the results of a direct comparison of howRu and EQ-5D in 116 patients at a cardiovascular out-patient clinic. howRu is shorter than EQ-5D, with better readability statistics, a higher completion rate, a wider range of states used and a smaller ceiling effect. The correlation between howRu and EQ-5D (r=0.70) is similar to those of other validated instruments with EQ-5D.

This describes the methods used and results from in 360 care homes in UK, Australia and New Zealand. Staff reported on 19,202 residents; 10,327 residents self-reported as well as 6,966 visitors. Residents with higher howRu scores reported better experience too. This demonstrated the practicality of measuring health status and experience at scale in care homes. The measures are simple to use, yet provide results that clearly discriminate between different homes, groups of residents and their experience.

This summarises the development of howRu and suggests how a holistic approach to natural language understanding (sentic computing) can supplement tools such as howRu in measuring quality and outcomes in health-care.

QALYs (Quality Adjusted Life Years) are widely used in economic evaluation in health care, but have been criticised. The Load Model is an alternative model. Load is the average annual weight attributed to morbidity and mortality over a defined period, using weightings based on preference judgements. In a worked example, the morbidity component is higher in the Load model than in the QALY model, based on otherwise identical assumptions. When comparing alternative outcomes, there are also large differences between the two models. Given the role of the QALYs in economic evaluation, the implications of an alternative, which generates such different results, warrants further exploration.

The first description of the Health Confidence Score, which is short, quick and easy to use. It includes results from two surveys (n=1031 and n=378). Correlation with the My Health Confidence scale is r=0.76. Other results were as predicted. People in poorer health tend to be less confident in their ability to deal with it.

This describes the origins and evolution of the Read Codes, which have been used by all GPs in UK and New Zealand. The Read Codes are one of the foundations of SNOMED CT.

Almost all British general practitioners use computers in their consulting rooms, but most hospital doctors do not. Over 30 years, leaders of the GP profession worked with government to provide incentives for computerising practices and to remove barriers. In hospitals computing was treated as a management overhead, and doctors had no incentives to become involved. The success of the government’s plans for “joined up” computer based health services depends on providing appropriate incentives to hospital doctors. GP computerisation has been a success, but what works in a GP surgery does not readily scale up to work in a hospital. Computer-based patient records have a more diverse range of uses in hospitals than in general practice, and simple unidimensional classification schemes such as the original Read codes cannot cope. In hospitals, many different computer systems need to be linked together, requiring common interoperability standards. Protection of privacy is a greater problem in hospitals, and the number of potential users makes greater demands on hardware and networks.

Healthcare interoperability delivers information when and where it is needed. Everybody stands to gain from safer more soundly based decisions and less duplication, delays, waste and errors. This book introduces healthcare interoperability and the main standards used.
The third edition includes a new part on FHIR (Fast Health Interoperability Resources), the most important new health interoperability standard for a generation. FHIR combines the best features of HL7’s v2, v3 and CDA while leveraging the latest web standards and a tight focus on implementation. FHIR can be implemented at a fraction of the price of existing alternatives and is well suited for mobile phone apps, cloud communications and EHRs.
The book is organized into four parts. The first part covers the principles of health interoperability, why it matters, why it is hard and why models are an important part of the solution. The second part covers clinical terminology and SNOMED CT. The third part covers the main HL7 standards: v2, v3, CDA and IHE XDS. The new fourth part covers FHIR and has been contributed by Grahame Grieve, the original FHIR chief.
