Ongoing support after the death of a patient L25(L1) Within one working week after a death, the specialist nurse, or other named support, will contact the Immediate family at a mutually agreed time and location. L26(L1) Within six weeks of the death, the identified lead doctor will write to offer the opportunity for the Immediate partner/family or carers to visit the hospital team to discuss the patient’s death. This should, where possible, be timed to follow the results of a post-mortem or coroner’s investigation. The partner/family or carers will be offered both verbal and written information that explains clearly and accurately the treatment plan, any complications and the cause of death. Partners/families or carers who wish to visit the hospital before their formal appointment should be made welcome by the ward team. L27(L1) When a centre is informed of an unexpected death, in another hospital or in the community, the Immediate identified lead doctor will contact the partner/family or carers. Section M - Dental Standard Implementation Adult timescale M1(L1) Patients will be given appropriate evidence-based preventive dental advice at time of congenital Immediate heart disease diagnosis by the cardiologist or nurse. M2(L1) All patients with planned elective cardiac surgery or intervention must have a dental assessment as Immediate part of pre-procedure planning to ensure that they are dentally fit for their planned intervention. M3(L1) All patients at increased risk of endocarditis must have a tailored programme for specialist follow-up. Immediate M4(L1) Each Congenital Heart Network must have a clear referral pathway for urgent dental assessments Immediate for congenital heart disease patients presenting with infective endocarditis, dental pain, acute dental infection or dental trauma. All patients admitted and diagnosed with infective endocarditis must have a dental assessment within 72 hours. A5(L2) There will be specific protocols within each Congenital Heart Network for the transfer of patients Within 6 months requiring interventional treatment. A6(L2) All patients transferring across or between networks will be accompanied by high quality Immediate information, including a health records summary (with responsible clinician’s name) and a management plan. Section A – The Network Approach Standard Implementation Adult timescale governance arrangements including oversight by the network lead congenital interventionist. Immediate Exceptions to this principle will include the exercise of patient choice and, when justified by a consideration of the clinical facts of the individual case, the exercise of referrer choice. B2(L2) All patients requiring investigation and treatment will receive care from staff trained in safeguarding Immediate standards, in accordance with the requirements of their profession and discipline. The precise number, above the minimum two, and location of these nurses will depend on geography, population and the configuration of the network. The size of the team will depend on the configuration of the service, the population served, and whether the service is integrated with paediatric echocardiography. C2(L2) There must be facilities in place to ensure easy and convenient access for partners/ family/carers. C3(L2) All adult patients must be seen in an appropriate adult environment as an outpatient, be Immediate accommodated in an exclusively adult environment as an inpatient and offered cultural and age- appropriate cardiac rehabilitation, taking into account any learning or physical disability. C4(L2) Patients must have access to general resources including books, magazines and free wifi. Immediate Free wifi: 6 months C5(L2) Patients and their partners/family/carers must be provided with accessible information about the Immediate service and the hospital, including information about amenities in the local area, travelling, parking and public transport. Section C - Facilities Standard Implementation Adult timescale C6(L2) If an extended hospital stay is required, any parking charges levied by the hospital or affiliated Immediate private parking providers must be reasonable and affordable. Each hospital must have a documented process for providing support with travel arrangements and costs. Consultants from the following services must be able to provide emergency bedside care (call to bedside within 30 minutes). Immediate D2(L2) Airway Team capable of complex airway management and emergency tracheostomy (composition Immediate of the team will vary between institutions). Radiological and echocardiographic images must be stored digitally in a suitable format and there must be the means to transfer digital images across the Congenital Heart Network. Senior decision makers from the following services must be able to provide emergency bedside care (call to bedside within 30 minutes) 24/7. Immediate D8(L2) Cardiac anaesthetist who works closely with specialist congenital cardiac anaesthetists in the Immediate network. Immediate D11(L2) Bereavement Support, including nurses trained in bereavement support. Immediate D17(L2) General medicine and provision for diabetes, endocrinology and rheumatology services. Consultants from the following services must be able to provide urgent telephone advice (call to advice within 30 minutes) and a visit or transfer of care within four hours if needed. The services must be experienced in caring for patients with congenital heart disease. Section D – Interdependencies Standard Adult Implementation timescale Advice and consultation must be available from the following services at least by the following working day. Section E – Training and education Implementation Standard Adult timescale E1(L2) All healthcare professionals must take part in a programme of continuing professional development Immediate as required by their registering body and/or professional associations. This should include both specialist education and training and more general training including safeguarding, working with adults with learning disability, life support, pain management, infection control, end-of-life, bereavement, breaking bad news and communication. Identified members of the medical and nursing team will need to undergo further in- depth training. E5(L2) Each Congenital Heart Network will have a formal annual training plan in place, which ensures Within 6 months ongoing education and professional development across the network for all healthcare professionals involved in the care of patients with congenital heart problems. The competency-based programme must focus on the acquisition of knowledge and skills such as clinical examination, assessment, diagnostic reasoning, treatment, facilitating and evaluating care, evidence-based practice and communication. Skills in teaching, research, audit and management will also be part of the programme. F2(L2) All clinical teams within the Congenital Heart Network will operate within a robust and documented Within 1 year clinical governance framework that includes: a. Participation in a programme of ongoing audit of clinical practice must be documented. F6(L2) Audits must take into account or link with similar audits across the network, other networks and Immediate other related specialties. Section F – Organisation, governance and audit Standard Implementation Adult timescale F7(L2) Current risk adjustment models must be used, with regular multidisciplinary team meetings to Within 1 year discuss outcomes with respect to mortality, re-operations and any other nationally agreed measures of morbidity. F11(L2) Where cases are referred to the specialist multidisciplinary team for a decision on management, Immediate they must be considered and responded to within a maximum of six weeks and according to clinical urgency. Immediate G2(L2) Where they wish to do so, patients should be supported to be involved in trials of new technologies, Immediate medicines etc.
