Summary
Background and study aims
In 2011 a research study compared child health in the UK with other European countries. It was worrying that UK measures of child health were amongst the worst in Europe. It is not clear why that is and further work needs to be done to better understand this. In hospital staff try to quickly identify the children who are seriously ill or getting sicker, so that they receive rapid treatment to improve their condition. Despite training, sometimes children become sicker in hospital without staff noticing or they underestimate the severity of illness, or do not treat deterioration quickly enough, or get extra help. In these cases the very sick child might require emergency transfer to intensive care, or stop breathing, or die unexpectedly. This study aims to develop an understanding of a number of key pieces of information that could help to standardise monitoring of children in hospital, help to identify deterioration quickly so there is an urgent response to save the patient from harm and reduce premature death in hospitalised children across the UK. This research study will be conducted in four hospitals and aims to examine what key components should be included in a track and trigger score and early warning system, to help identify the children who are sicker and prevent them becoming more unwell, having a serious complication or dying. This will be the largest, most comprehensive study of paediatric early warning scores and systems, with the aim to improve patient safety and reduce mortality. Our findings will inform recommendations about safety processes that should be established in every hospital treating paediatric in-patients across the NHS.

Who can participate?
All children admitted to the four participating hospital's inpatient units general hospital wards (excluding high dependency and intensive care units), the parents of some of these children and the healthcare professionals looking after some of these children.

What does the study involve?
This study will develop a tool for healthcare professionals to use to monitor sick children. Before this is introduced we need to understand how staff currently monitor children, how they communicate with each other and how they record symptoms. We will observe and interview healthcare professionals working on paediatric wards and parents of children on the ward to see how best to develop a track and trigger tool to help monitor patients. We will use this information as well as published research literature to develop a track and trigger tool that can be used to help staff monitor children who are getting sicker. We will continue to observe and interview staff and parents to see how well the new tool is accepted into working practice.

What are the possible benefits and risks of participating?
There are no direct benefits to the parents or healthcare professionals taking part in these discussions, but they may gain indirect benefit by talking about their experiences in a supportive environment. We hope that the study will help us to identify and better understand the best way to monitor children and identify when they get sicker. Our future aim is to use the findings from this project to roll out a national system. Observation and interviews will make certain demands on staff. We will be attentive to service issues and ensure that our study does not disrupt practice. The parents who agree to participate will only have the time burden of participating in an interview and if any parents who child has deteriorated chose to be interviewed, they may become upset when talking about their child and their experience.

Where is the study run from?
Alder Hey Hospital, Arrow Park Hospital, Children’s Hospital of Wales and Morriston Hospital (UK).

When is the study starting and how long is it expected to run for?
From November 2014 to November 2018.

Who is funding the study?
NIHR - Health Services & Delivery Research Programme (UK).

    2. What is the evidence that the implementation of paediatric track and trigger tool in the UK NHS environment will reduce avoidable morbidity and mortality in hospitalised children?
    3. What are the (micro, meso and macro) contextual features consequential for its success?
    4. What factors are necessary to support successful implementation and normalisation?

Study Type
Observational
Intervention

Workstream 1 - The development of a track and trigger tool and an implementation package based on systematic review and expert consultation
A systematic review will be conducted in order to answer three interlinked questions:
1. How well validated are existing track and trigger scores for PEWS and their component parts?
2. How effective are PEWS (with or without track and trigger scores) at reducing mortality and critical events?
3. What socio-technical and contextual factors are associated with successful or unsuccessful PEWS (with or without track and trigger scores)?
Drawing on the evidence from the literature review, the PUMA study team will devise an optimal track and trigger tool, with the review informing the development of the items to be included in the score and the system that will inform how the score is used. This will be reviewed by key expert stakeholders to ensure face and internal validity and inform layout, format and feasibility.
After development, the new tool will be field tested for feasibility. Feasibility testing will involve feedback from medical, nursing and support staff who use the tool to assess clarity and utility.

Workstream 2 - A prospective mixed method, before-and-after study design in four hospitals, with embedded case studies is proposed
These embedded case studies within the study at each phase will evaluate normal practice, the process of implementation and the use of the track and trigger tool post implementation.

Phase 1: Observe and record outcomes in current practice
Organisational case studies (one ward) will be undertaken in each hospital. Ethnographic methods will be deployed to explore the technical, social, and organisational factors consequential for PEW tool effectiveness at individual, team, unit and hospital level. Data will be generated pre-intervention and post-intervention in order to understand the impact of PEW tool implementation on practice and identify the micro, meso and macro contextual features consequential for effectiveness.

Phase 2: Implement the track and trigger tool based on best evidence, and the implementation package
An implementation strategy will be tailored to each organisation.
We anticipate developing an implementation package adopting a train the trainers approach. The implementation package will include a manual for implementation at an organisational level as well as a ‘user guide’ for staff directly using the tool and system.

Phase 3: Evaluate the system in use
Observational methods will be employed to describe and understand the implementation of the train the trainers programme in each of the four study sites to identify any significant variation in the delivery of the intervention, local issues that may surface in relation to the challenges of implementation, and any proposed adaptations and solutions.

Intervention Type
Mixed
Primary Outcome Measures
    The primary outcome measure is the monthly collected rate of mortality and the following critical events:
    1. Unplanned admission to Paediatric Intensive Care (PICU) or Paediatric High Dependency Unit (PHDU)
    2. Cardiac arrest
    3. Respiratory arrest
    4. Medical emergencies requiring immediate assistance (arrest calls who were not respiratory or cardiac arrests)
    5. Referrals for PICU review (in tertiary centres) or PICU retrieval (DGHs)
    6. The Critical Deterioration (CD) metric
Secondary Outcome Measures
    The secondary outcome measures are the monthly rates of each of the following critical events in each hospital:
    1. Mortality
    2. Unplanned admission to PICU or PHDU
    3. Cardiac arrest
    4. Respiratory arrest
    5. Medical emergencies requiring immediate assistance
    6. Referrals for PICU review (in tertiary centres) or PICU retrieval (DGHs)
    7. CD metric
    8. PIM3
