An Evaluation of early stage development of rotating paramedic model pilot sites
This report, commissioned by Health Education England, aims to evaluate the development of a rotating paramedic model of care delivery designed to address both the career aspirations of specialist paramedics and the combined workforce issues in ambulance services and primary care so that all, not just some, of the healthcare sectors can benefit. The fundamental principle of this model is that, rather than working within a single environment, a specialist or advanced paramedic can ārotateā through different sectors of the healthcare system whilst remaining employed by one employer
Why I Write?
Why do I write? This is like being asked why do I breathe, eat, sleep; and the short answer is because it is impossible to do otherwise. Even before the first geographical dislocation in my life (the 1000 mile move, at the age ol7, from Melbourne to Brisbane which are two different countries), I found it necessary to tell myself stories - and indeed to write them down In little notebooks - to explore the meaning of the bewildering contradictions I kept bumping into. From my first day at school, I felt like a space voyager, travelling daily between alien planets whose languages and customs were incomprehensible to each other. (This turned out to be good training for the rest of my life.
What do users value about the emergency ambulance service?
Introduction: Response times have been used as a key quality indicator for emergency ambulance services in the United Kingdom, but criticised for their narrow focus. Consequently, there is a need to consider wider measures of quality. The patient perspective is becoming an increasingly important dimension in pre-hospital outcomes research. To that end, we aimed to investigate patientsā experiences of the 999 ambulance service to understand the processes and outcomes important to them.
Methods: We employed a qualitative design, using semi-structured interviews with a purposive sample of people who had recently used a 999 ambulance in the East Midlands. We recruited patients of different age, sex, geographical location, and ambulance service response including āhear and treatā, āsee and treatā and āsee and conveyā.
Results: We interviewed 20 service users. Eleven men and nine women participated and 12 were aged 65 years and over. Users valued a quick response when they perceived the call to be an emergency. This was of less value to those who did not perceive their situation as an emergency and irrelevant to āhear and treatā users. All users valued the professional approach and information and advice given by call handlers, crew and first responders, which provided them with reassurance in a worrying situation. āSee and conveyā users valued a seamless handover to secondary care.
Limitations: We found it challenging to engage participants to consider quality indicators beyond response times because these were considered to be abstract in comparison with their concrete experiences.
Conclusions and recommendations: Aspects other than response times were important to patients, particularly in situations perceived by patients to be non-emergency. The results will be combined with issues identified from systematic reviews and used in a Delphi study to identify candidates for new outcome measures for emergency ambulance services
Developing new ways of measuring the impact of ambulance service care
Background
Pre-hospital care in England is provided by ambulance services who deliver a diverse range of services to over 9 million patients a year but there is limited evidence about the effectiveness of this care. Historically ambulance performance has been measured by response times rather than clinical need or effectiveness. Progress on developing more appropriate performance measures is constrained by a lack of information about what happens to patients and their outcome after the pre-hospital component of care. If ambulance service information about patients could be linked to process and outcome data further along the care pathway then relevant measurement tools could be developed that allow a better assessment of the impact of pre-hospital care. The Pre-hospital Outcomes for Evidence Based Evaluation (PhOEBE) project is a 5 year programme of research funded by the UK National Institute of Health Research.
Aims & objectives
The aim of the programme is to develop new ways of measuring the impact of care provided by the ambulance service to support quality improvement through monitoring, audit and service evaluation.
The objectives are to: 1) Review and synthesise the research literature on pre-hospital care outcome measures and identify measures relevant to the NHS and patients for further development; 2) Create a dataset linking routinely collected pre-hospital data, hospital data and mortality data to provide outcome information; 3) Develop new ways of measuring process and outcome indicators including building risk adjustment models that predict the outcomes using the linked data; 4) Explore the practical use of the linked dataset and the risk adjustment models to measure the effectiveness and quality of ambulance service care.
Research plans
The programme has 4 linked stages;
1. Synthesis of evidence on outcome measures and identification of measures for further development - review and assessment of the evidence base on outcome measurement for pre-hospital care and a consensus studies to identify measures relevant to patients and NHS staff.
2: Linking pre-hospital data with other patient data sources ā creating a single dataset that links ambulance service electronic care records with routinely collected Hospital Episode Statistics (HES) and national mortality data.
3. Development of risk adjustment models for outcomes in patients attended by the ambulance service ā using the linked data to develop risk adjustment tools that will allow patient differences to be taken into account and differences between expected and actual outcomes to be detected. Particular emphasis will be made to include the broad EMS population and not specific conditions as has been the case in the past.
4. Testing the risk adjustment models to assess if they can be used to measure effectiveness and quality ā exploring the practical application of the measures by using them to assess if different ways of providing ambulance service care result in different consequences for patients.
Outputs, outcomes and impact
The programme will:
ā¢ Provide a summary of relevant evidence on pre-hospital care outcome measurement
ā¢ Develop a method for linking healthcare information into a format that can be used to support quality improvement, is acceptable to patients and complies with information legislation
ā¢ Develop population based models for measuring the impact of pre-hospital care that can be used to monitor quality and safety, evaluate new service innovations and support quality improvement
ā¢ Provide added value by using routine information and NHS infrastructure to operationalise the process and outcome models so that they will be of use across the NHS
Progress to date
The programme commenced in June 2011 and ends in May 2016. Two systematic reviews of measures used to measure the impact of ambulance service care (one policy literature and one research literature based) have been completed as has a qualitative study of recent service users to identify aspects of service they value. Potential measures identified by these studies were presented at a consensus conference and then further refined in a Delphi study to prioritise and identify measures for further development. Linked data is currently being created and the next stage will be the development of risk adjusted predictive models for the final identified measures
Prioritising pre-hospital outcome measures with a multi-stakeholder group: a consensus methods study
Context: A consensus event to discuss and prioritise ambulance service care outcome measures was held with 43 participants from a range of professional backgrounds including Commissioners; Policy makers; clinicians; managers; academics and patient and public representatives.
Problem: Ambulance services in England manage 8 million emergency calls per years and treat 6.5 million people. Services are currently unable to ascertain whether the care they provide is safe, effective and of good quality as they receive no information about patients once they have been discharged from their care. The lack of robust patient focussed outcome measures for ambulance care means there is no opportunity for identifying and sharing good practice, identifying problems and measuring the impact of service developments and innovations.
Assessment of problem and analysis of its causes: Historically ambulance service performance has been measured using response time as a proxy measure for quality. Although the limitations of this measure are recognised there is a lack of consensus on which outcome measures are important and little opportunity to measure alternatives due to poor information on what happens to patients after their ambulance service contact. The PhOEBE NIHR research programme aims to develop a linked ambulance service and secondary care dataset and to assess quality of care in this patient group using outcome measures identified from the literature and in consultation with different stakeholder groups. This means that for the first time the ambulance service will be able to assess the quality of care they provide to patients, rather than just how quickly the ambulance arrived.
Intervention: Potential outcome measures identified from 2 systematic reviews were categorised into 1 of 3 headings (Service/operational, patient management and patient outcomes) and participants were pre-allocated to a discussion group. All discussion groups contained participants representing a range of stakeholder view points. Participants took part in small group themed discussions relating to a number of pre-specified outcome measures. They were also able to add to the list of measures. Directly following the discussion participants voted on the importance of the outcome measures in relation to ambulance service care quality. This was done using Turning Point software. Participants rated each outcome measure as either āEssentialā, āDesirableā or āIrrelevantā using individual key pads. The voting was done independently and anonymously. Real time results were displayed following each vote.
Study design: We used an interactive voting system coupled with a modified nominal group technique for the prioritisation of potential ambulance service outcome measures.
Strategy for change: Following on from this study the top ranking outcome measures will be further refined as part of a Delphi study, before using the outcome measures to assess ambulance service quality of care in our linked data sample. The methods for linking the ambulance service data to other health care information and the identified outcome measures will enable all UK ambulance services to assess the quality of care they provide to patients and the impact of any service changes on care quality and patient outcomes.
Measurement of improvement: The results from the outcome prioritisation voting exercise were ranked based on the highest proportion of āEssentialā rated measures. Where over 50% of participants rated a measure as āEssentialā these were taken forward and considered in further consensus studies.
Effects of changes: From undertaking the consensus event we have prioritised potential ambulance service outcome measures.
Lessons learnt: We have established that it is possible to incorporate voting technology into consensus methodologies and provide real time results to participants.
Message for others: This research prioritised ambulance service outcome measures. Out of the 40 number of measures considered, the top 5 measures were Accuracy of dispatch decisions; Completeness and accuracy of patient records; Accuracy of call taker identification of different conditions; pain measurement and symptom relief and Patient experience
Prehospital outcomes for ambulance service care: systematic review
Background: Ambulance service performance measurement has previously focused on response times and survival. We conducted a systematic review of the international literature on quality measures and outcomes relating to pre-hospital ambulance service care, aiming to identify a broad range of outcome measures to provide a more meaningful assessment of ambulance service care.
Methods: We searched a number of electronic databases including CINAHL, the Cochrane Library, EMBASE, Medline, and Web of Science. For inclusion, studies had to report either research or evaluation conducted in a pre-hospital setting, published in the English language from 1982 to 2011, and reporting either outcome measures or specific outcome instruments.
Results: Overall, 181 full-text articles were included: 83 (46%) studies from North America, 50 (28%) from Europe and 21 (12%) from the UK. A total of 176 articles were obtained after examining 257 full-text articles in detail from 5,088 abstracts screened. A further five papers were subsequently identified from references of the articles examined and studies known to the authors. There were 140 articles (77%) which contained at least one survival-related measure, 47 (34%) which included information about length of stay and 87 (48%) which identified at least one place of discharge as an outcome.
Limitations: We encountered the problem of incomplete information, for instance studies not specifying which pain scales when these had been used or using survival without a specific time period.
Conclusion and recommendations: In addition to measures relating to survival, length of stay and place of discharge, we identified 247 additional outcome measures. Few studies included patient reported or cost outcomes. By identifying a wide range of outcome measures this review will inform further research looking at the feasibility of using a wider range of outcome measures and developing new outcome measures in prehospital research and quality improvement
How should we measure ambulance service quality and performance?
The problem
Ambulance services in England treat 6.5 million people per year but get no information about what happens to patients after discharge. This has led to a reliance on measuring response times rather than outcomes to assess how well services perform, and little opportunity for identifying problems and good practice or evaluating service developments.
Research aim
There is a lack of consensus on which outcome measures are important for pre-hospital care so we set out to address this within the Prehospital Outcomes for Evidence Based Evaluation (PhOEBE) research programme.
Methods
We conducted a two round Delphi study to prioritise outcome measures identified from a systematic review and a multi-stakeholder consensus event. 20 participants scored 57 measures over two rounds. Participants included policy makers and commissioners, clinical ambulance service and ambulance service operational groups. Outcomes were scored in three categories: patient outcomes; whole service measures and clinical management.
Results
Highly ranked patient outcome measures related to pain, survival, recontacts and patient experience. High ranking outcomes in the Clinical Management group related to compliance with protocols and guidelines and appropriateness and accuracy of triage. In the Whole Service measures group highly ranked measures related to completeness of clinical records, staff training and time to definitive care.
Conclusions
The next steps are to identify which measures are suitable for measuring with routine data; use a linked dataset to build predictive models and determine what aspects of care can predict good or poor outcomes (mortality and non-mortality); measure the effectiveness and quality of ambulance service care, and; assess the practical use of the measures and the linked data as a way to support quality improvement in the NHS
Prioritising outcomes measures for ambulance service care: a three stage consensus study
Background
Historically ambulance care quality and performance has been measured by response times rather than clinical need or effectiveness. This limits the evidence about the effectiveness of the care the ambulance service provides. The Pre-hospital Outcomes for Evidence Based Evaluation (PhOEBE) project is a 5 year research programme which aims to develop new ways of measuring the performance, quality and impact of ambulance service care that better reflect the care provided.
Methods
We held a 1 day consensus event with a multi-stakeholder group to identify and prioritise which features of ambulance service care are important and worth further development as measures of performance and quality. The day comprised a series of small group discussions to share opinions about measures identified from literature reviews and the opportunity for participants to add their ideas, together with a live vote to help identify and rank measures for further development. Time measures were considered in a separate online questionnaire. The results from the online questionnaire and Consensus Event were fed into a Delphi study.
Results
43 participants attended the consensus event, representing a range of participant groups including patient and public, ambulance services, commissioners and policy groups. The top 5 outcome measures prioritised by the participants were: accuracy of dispatch decisions; completeness and accuracy of patient records; accuracy of call taker identification of different conditions or needs (e.g. heart attack, stroke, suitable for nurse advice); pain measurement and symptom relief; and patient experience. From the online survey of time measures the top 5 measures were time of call to time of arrival at scene; time symptoms start (e.g. chest pain) to time of treatment with balloon for heart attack; time taken to answer the emergency call; total time spent on scene; and incident or start of symptoms to calling the ambulance service.
Conclusion
Using consensus methods we have identified a set of outcome measures that can potentially be used to measure the performance and quality of ambulance service care. Some of these measures fit with existing government targets, such as response times and time taken to answer the emergency call. However, most measures are new ways of measuring ambulance service care and the importance of these measures and methods of measurement will be assessed as part of an on-going Delphi study
What outcome measures should be developed for pre-hospital care?: results of a consensus event
Background: The PhOEBE (Pre-hospital Outcomes for Evidence Based Evaluation) project is a 5-year research programme which aims to develop new ways of measuring the performance, quality and impact of ambulance service care. As part of this programme we conducted 2 systematic reviews to identify potential measures and held a consensus event to prioritise these measures.
Methods: Actual or potential measures or indicators for assessing ambulance service performance or quality of care were identified from two systematic reviews and categorised as clinical management, operational or patient based measures. Time measures were considered separately. We held a consensus event with participants representing clinicians, ambulance operations, commissioners, policy and academic research. Three small group discussion sessions were held and after each session we used turning point software for participants to electronically vote whether they thought each potential measure was essential, desirable or irrelevant.
Results: 42 participants took part and discussed and voted on 52 different measures. They could also add measures. The top 5 ranked operational measures were concerned with completeness and accuracy of records; accuracy of triage; appropriateness of service; ambulance training and ambulance utilisation. Top 5 clinical measures were accuracy of dispatch decisions, accuracy of problem identification, compliance with end of life care plans; patient safety and compliance with protocols. The top 5 patient measures were measurement and relief of pain; patient experience; return of spontaneous circulation; complications from care and survival.
Conclusions: Accuracy of different types of decision making and compliance with management protocols predominated as essential with pain management the most important patient measure. Management of end of life care was identified by participants. The electronic voting system which provided instant real time feedback was well received by participants. The next stage is a Delphi survey to further refine these measures and include time interval measures
