2 Equality & Diversity statement The Trust strives to ensure its policies are accessible, appropriate and inclusive for all. Therefore all policies will be required to undergo an Equality Impact Assessment and will only be approved once this process has been completed. The Trust aspires to: Ensure the health and wellbeing of those we serve and be a leader in the development of mental health care and treatment. To achieve such an aim, the Trust will need to address the issues raised by its stakeholders and deliver the kind of service developments and outcomes they describe. Such an endeavour needs to be underpinned by a core set of values. West London Mental Health NHS Trust Page 2 of 15

5 MEWS 1.0 INTRODUCTION 1.1 Primary Policy: The Trust s Physical Healthcare Strategy describes interconnection between mental and physical health. They state having a mental problem increases mortality from heart disease (1); coronary heart disease can increase the risk of depression (2). People with schizophrenia have a life expectancy that is significantly lower than that of the general population and have higher rates of serious long term conditions(3)(4) People with mental health problems are also prone to factors that are damaging to overall health, such as poor diet, heavy smoking and drug and alcohol misuse(3). Equally, people who smoke, are obese or take drugs or behave in other ways that put their health at risk are more likely to have mental health problems(5) and may people in Mental Health Services will have co-morbid physical health problems such as long term conditions and complex end of life care needs. (Ref Physical Healthcare Strategy P2). 2.0 PURPOSE 2.1 The aim of this policy is to improve people s outcomes by detecting and acting upon early signs of deterioration in physical health of patients. This will be in part achieved through the implementation of the Modified Early Warning Scores (MEWS) system that: Identifies trends in patient observations; Ensures that timely patient review and appropriate treatment occurs; and Improves the documentation of patient observations. 2.2 Notification should also occur where clinical deterioration occurs other than that assessed by the MEWS criteria, or where sound clinical judgement would suggest that notification is in the best interests of patient care. 3.0 SCOPE 3.1 All staff are to apply the Modified Early Warning Scores (MEWS) system when patient observations are taken. 3.2 It does not only apply to children, or young adults under the age of 18 years 3.3 It ONLY applies to people who are current in-patients of West London Mental Health Trust West London Mental Health NHS Trust Page 5 of 15

6 4.0 WHAT IS MEWS 4.1 The Modified Early Warning Score (MEWS) is an evidenced based system of care, used in many acute hospitals to monitor the progress of patients, and to identify early, a deterioration in their health. 4.2 The Modified Early Warning Score (MEWS) is a form of track and trigger scoring system. The triggers are based on routine observations and are sensitive enough to detect subtle changes in a patient s physiology which will be reflected in a change of score should the patient be improving or deteriorating. 4.3 All patients have their vital signs measured and these are converted into a score. The higher the score the more abnormal the vital signs are. If the scores reach above a certain threshold, a doctor must be called to assess the patient. 4.4 The system allows for the regular monitoring and recording of blood pressure, pulse, temperature, Conscious state and respiratory rate. 4.5 Early warning scoring systems were originally developed with 2 specific aims: to facilitate timely recognition of the patients with established or impending critical illness; and to empower nurses and junior medical staff to obtain experienced help through the operation of a trigger threshold which, if reached, required mandatory attendance by a more senior member of staff. 4.6 Use of a Modified Early Warning Scoring system can also: Improve the quality of patient observation and monitoring Improve communication within the multidisciplinary team Allow for timely admission to intensive care (Acute Hospital) Support good medical judgement Aid in securing appropriate assistance for sick patients Give a good indication of physiological trends Are a sensitive indicator of abnormal physiology NB It is important that staff understand that MEWS does not replace Clinical Judgement 5.0 RECOGNISING A PHYSICALLY DETERIORATING PATIENT 5.1 Clinical deterioration can occur at any stage of a patient s illness, although there will be certain periods during which a patients is more vulnerable such as at the onset of illness, during surgical or medical interventions and during recovery from critical illness. 5.2 Patients wish a diagnosed physical health condition or illness must have a secondary diagnosis recorded on RIO and agreed care plan must be written detailing the treatment plan including the signs and symptoms associated with deterioration.

7 5.3 The symptoms below indicate deteriorating health. The more of these symptoms the patient has and the more intense they are and also the longer the patient has had them then the greater the urgency to begin initiating increased observation. 6.0 WHEN TO USE MEWS 6.1 MEWS relies on the routine recording and charting of the physiological status of the patient however, the frequency of monitoring should be increased if abnormal physiology is observed.. These are simple observations that can be performed by a nurse, doctor or other trained staff. These observations include: Pulse Respiratory Rate Temperature Blood Pressure Conscious State (AVPU) 6.2 In specific clinical circumstances additional monitoring should be considered for example: urine output Biochemical analysis Pain assessment 6.3 The MEWS evidence base does not apply to children therefore this guidance is only applicable to adults and older people. All patients who are admitted to an in-patient ward should have, on admission, the five elements recorded: The baseline observations Thereafter, at a minimum, the same observations should be recorded monthly. 6.4 There may be clinical indications when it will be appropriate to record the five elements more frequently. For example: - Unstable patients with a long term condition i.e. Diabetes Service users whose physical condition is causing concern Service users who have been transferred from an acute hospital Service users with a chronic health problem 6.5 Previous recording will provide a base line from which the new observations can be compared, and thus provide important information on how the physical state of the patient has changed. The frequency and specifications of all baseline observations should be prescribed in the Nursing Care plan. It may also be necessary to assess a service user using the MEWS score prior to transferring them to an external healthcare provider. West London Mental Health NHS Trust Page 7 of 15

8 7.0 OBSERVATION CHART 7.1 The Trust has a standard MEWS system for use across all Trust provided services. 7.2 MEWS is incorporated within the Standard Observation Chart. 8.0 MEWS SCORE 8.1. Where there are concerns that a patient is unwell the MEWS observations are carried out and the results used to gauge the severity of deterioration as indicated. Table 1 Pulse Respiratory Temperature 0c Conscious State AVPU MEWS Score Systolic BP < < Alert Voice Pain Unresponsive > 200 AVPU is a simple assessment where A = Alert V = Responds to verbal commands only P = Responds to Pain U = Completely Unresponsive A flow diagram for the use of MEWS is shown in Appendix A. 9.0 TRIGGER SCORES 9.1 A MEWS Score of 1 in ANY category indicates the need for close and frequent observation of the patient. The senior nurse on duty should be informed immediately, and will assess the patient within 60 minutes. 9.2 A change in the MEWS score of 2 or more indicates that the patient is potentially unwell and means that urgent medical attention is required. The duty doctor should be informed immediately, and should attend within 15 minutes HOW TO RESPOND TO MEWS 10.1 The Senor Nurse will assess the patient and provide guidance to the ward staff on the further frequency of recording of physical signs, and other action that may be West London Mental Health NHS Trust Page 8 of 15

9 appropriate, depending on the clinical state of the patient. If necessary, the senior nurse will also seek the opinion of the duty doctor, although it may only be telephone advice that is necessary The duty doctor will respond to a patient s physical state changing by more than 2 points within 15 minutes. The duty doctor will assess the patient, and arrange for the appropriate care to be delivered. This may involve further monitoring, administration of medication, seeking specialist review, or transferring the patient to a more appropriate location depending on the clinical symptoms and signs This response should be no different whether or not the recording takes place in hours or out of hours and at weekends. N.B. A failure to attend a MEWS call within an acceptable timescale (<30 minutes) should result in the completion of an incident form A MEWS action plan must be agreed and documented for any patient reviewed RECORDING MEWS 11.1 Observations and MEWS Scores MUST be recorded on the Trust MEWS Observation Chart See Appendix The decision to initiate a MEWS Call (that is a significant change from base line) must be recorded in the patient s notes MEWS TRAINING 12.1 Medical staff will receive information, instruction and training on the MEWS System on induction and within core-curriculum teaching. Nursing staff will receive information, instruction and training on the MEWS system and accurate observations as part of Local Induction and as part of local ward/department training. MEWS training will be mandatory for registered nursing staff Staff caring for patients with physical conditions should have competencies in monitoring, measurement, interpretation and prompt response to the acutely ill patients appropriate to the level of care they are providing. Education and training should be provided to ensure staff have these competencies and they should be assessed to ensure they can demonstrate them. Pocket size (laminated) cards will be made available for all nursing staff. Laminated posters will be displayed in all treatment and clinical rooms. An aide memoir regarding MEWS will be included with the RIO Physical Healthcare screening field. West London Mental Health NHS Trust Page 9 of 15

10 A standard MEWS training resource pack will be provided to (and made available on The Exchange s Physical Healthcare Page) for all Clinical Leaders and Clinical Managers MONITORING & AUDIT An audit of implementation of MEWS will be undertaken annually by the Clinical Service Units (CSU). Results of the audit will be presented to the Physical Health Group and Clinical Effectiveness Group The Trust Physical Healthcare Group will review this policy annually ASSOCIATED POLICES The Physical Healthcare Policy (P15) Physical Healthcare Strategy.
