Heart valve service provision in the United Kingdom and the effect of the COVID 19 pandemic; improved but must do better. A British Heart Valve Society national survey

BACKGROUND

Outpatient care for patients with heart valve disease (HVD) is best provided by valve clinics delivered by specialists. Modern day practice in the United Kingdom (UK) is currently poorly understood and has not been evaluated for nearly a decade. Furthermore, the COVID 19 pandemic changed the management of many chronic diseases, and how this has impacted patients with heart valve disease is unclear.

METHODS

A British Heart Valve Society survey was sent to 161 hospitals throughout the UK.

RESULTS

There was a general valve clinic in 46 of the 68 hospitals (68%), in 19 of 23 Heart Centres (83%) and 29 of 45 DGHs (64%). Across all settings, 3824 new patients and 17,980 follow up patients were seen in valve clinics per annum. The mean number of patients per hospital were 197 (median 150, range 48-550) for new patients and 532 (median 400, range 150-2000) for follow up. On the day echocardiography was available in 55% of valve clinics. In patients with severe HVD, serum brain natriuretic peptide (BNP) was measured routinely in 39% of clinics and exercise testing routinely performed in 49% of clinics. A patient helpline was available in 27% of clinics. 78% of centres with a valve clinic had a valve multidisciplinary team meeting (MDT). 45% centres had an MDT co-ordinator and MDT outcomes were recorded on a database in 64%. COVID-19 had a major impact on valve services in 54 (95%) hospitals.

CONCLUSIONS

There has been an increase in the number of valve clinics since 2015 from 21 to 68% but the penetration is still well short of the expected 100%, meaning that valve clinics only serve a small proportion of patients requiring surveillance for HVD. COVID-19 had a major impact on the care of patients with HVD in the majority of UK centres surveyed.

Shared Decision-Making and Patient-Reported Outcome Measures in Valvular Heart Disease

Patient-centered health care emphasizes shared decision-making (SDM), incorporating both clinical evidence and patient preferences and values. SDM is important in heart valve disease, both because there might be more than one treatment option and due to the importance of adherence after intervention. We aimed to describe patient information and involvement in decision-making about care and recording of patient-reported outcome measures (PROMs) in valve interventions. The opinion piece and recommendations are based upon literature review and our own experience from specialist valve clinics. Before a valve intervention, adequate patient information, discussion of the various treatment options and exploring patient preferences, in line with the concept of SDM, may improve post-intervention quality of life. After intervention, patients with prosthetic heart valves require adequate counseling and close follow-up to make them more confident and competent to manage their own health, as well as to maintain the efficacy of treatment provided. PROMs inform SDM before and improve care after valve intervention, focusing on outcomes beyond mortality and morbidity. SDM may improve post-intervention quality of life. Formal PROMs questionnaires inform SDM, quantify patient centered changes and should be used more often in clinical practice and research. A thorough assessment of baseline frailty status in patients scheduled for valve intervention is essential and may affect postoperative outcome.

Specialist valve clinic in a cardiac centre: 10-year experience

Aims

Guidelines recommend specialist valve clinics as best practice for the assessment and conservative management of patients with heart valve disease. However, there is little guidance on how to set up and organise a clinic. The aim of this study is to describe a clinic run by a multidisciplinary team consisting of cardiologists, physiologist/scientists and a nurse.

Methods

The clinical and organisational aims of the clinic, inclusion and exclusion criteria, and links with other services are described. The methods of training non-clinical staff are detailed. Data were prospectively entered onto a database and the study consisted of an analysis of the clinical characteristics and outcomes of all patients seen between 1 January 2009 and 31 December 2018.

Results

There were 2126 new patients and 9522 visits in the 10-year period. The mean age was 64.8 and 55% were male. Of the visits, 3587 (38%) were to the cardiologists, 4092 (43%) to the physiologist/scientists and 1843 (19%) to the nurse. The outcomes from the cardiologist clinics were cardiology follow-up in 460 (30%), referral for surgery in 354 (23%), referral to the physiologist/scientist clinic in 412 (27%) or to the nurse clinic in 65 (4.3%) and discharge in 230 (15%). The cardiologist needed to see 6% from the nurse clinic and 10% from the physiologist/scientist clinic, while advice alone was sufficient in 10% and 9%.

Conclusion

A multidisciplinary specialist valve clinic is feasible and sustainable in the long term.

A Nurse Practitioner Clinic: A Novel Approach to Supporting Patients Following Heart Valve Surgery

BACKGROUND

Valvular heart disease is an important healthcare issue and its impacts are increasing. Following valve surgery, traditional models of care involve medical personnel, however, significant gaps in guideline adherence and delays in follow-up have been reported. Internationally, there is increasing evidence that specialist nurses can function in a variety of clinical settings and improve patient management.

METHODS

In 2009, a nurse practitioner clinic to support patients following valve surgery was established. We used a retrospective clinical audit and clinical review with descriptive statistics to describe the development of the clinic and to provide guidance for other services for model of care development.

RESULTS

Over four years, 462 patients have been reviewed at least once, with over half having multiple assessments, 37% had rheumatic heart disease. These patients were 20 years younger and more likely to be women, non-European, current smokers and have atrial fibrillation. All patients received a focussed lifestyle, rheumatic, thromboembolic and endocarditis risk and symptom review with tailored support, advice and referral where appropriate. Four percent were referred back to a cardiologist for early evidence of valve dysfunction and a further 1.5% required urgent admission for unstable symptoms.

CONCLUSION

The nurse practitioner clinic offers a systematic approach to promoting guideline adherence post valvular surgery. Important clinical symptoms and differences in health needs were identified and were actioned appropriately.
