Abstract Chronic disease management requires achievement of critical individualised targets to mitigate again long-term morbidity and premature mortality associated with diabetes mellitus.The responsibility for this lies with both the patient and health care professionals.Care plans have been introduced in many healthcare settings to provide a patient-centred approach that is both evidence-based to deliver positive clinical outcomes and allow individualised care.The Alphabet strategy (AS) for diabetes is based around such a care plan and has been evidenced to deliver high clinical standards in both well-resourced and underresourced settings.Additional patient educational resources include special care plans for those people with diabetes undertaking fasting during Ramadan,Preconception Care,Prevention and Remission of Diabetes.The Strategy and Care Plan has facilitated evidence-based,cost-efficient multifactorial intervention with an improvement in the National Diabetes Audit targets for blood pressure,cholesterol levels and glycated haemoglobin.Many of these attainments were of the standard seen in intensively treated cohorts of key randomized controlled trials in diabetes care such as the Steno-2 and United Kingdom Prospective Diabetes Study.This is despite working in a relatively under-resourced service within the United Kingdom National Health Service.The AS for diabetes care is a useful tool to consider for planning care,education of people with diabetes and healthcare professional.During the time of the coronavirus disease 2019 pandemic the risk factors for the increased mortality observed have to be addressed aggressively.The AS has the potential to help with this aspiration.

INTRODUCTION

One of the major global public health burdens of this current era,with over 450 million people affected globally,is type 2 diabetes mellitus[1].Advances in acute care have led to increased life expectancy for patients with diabetes through excellent emergency management of conditions such as acute coronary syndrome,stroke and sepsis.The challenge now is to effectively manage their chronic disease to reduce the other complications of diabetes[1].This has become especially important as the coronavirus disease 2019 (COVID-19) pandemic continues to spread globally with diabetes mellitus being identified as a significant risk factor for mortality (increased risk:× 2.86 for type 1 diabetes,× 1.80 for type 2 diabetes)[2].Additionally,poor glycaemic control,obesity,Black and South Asian ethnicities,and chronic kidney disease (CKD) were identified as significant risks for increased mortality in patients with diabetes and COVID-19[3].

A multifactorial approach for diabetes management to reduce complications is encouraged in the United Kingdom through the National Institute for Health and Care Excellence (NICE) guidelines,Scottish Intercollegiate Guidelines Network guidelines and the National Diabetes Audit (NDA).A recent report published by NDA showed that meeting all three treatment targets (glycated haemoglobin,blood pressure,statin prescription) was only achieved in 19.6% for type 1 diabetes and 40.5% for type 2 diabetes patients (In England)[4].Our institutional average of meeting these targets was 46.5%.It also observed that the percentage of patients receiving NICE recommended care processes has not shown significant improvement from 2012 to 2019.

CONCEPT OF CARE PLANNING

“Care planning” involves the process by which both health care workers and patients have detailed discussions on the condition that the patient has.An individualized plan of management is then agreed based on the patient’s personal values and aspirations for their life.The written document after this process of planning is the “Care plan”[5].The action plan and interventions required to manage an acute condition are very different than what is required to manage a chronic condition.At the same time,all chronic conditions,may if they differ in the involvement of organs of human body,have a common set of problems which need to be addressed by patient,their families and health carers.This concept is motivated by the physical,psychological and social needs which arise due to the chronic conditions of the patients.Care planning may save the enormous expenditure on chronic diseases which usually runs in billions of pounds[6].It is important to remember that in an average year of 8766 h,a patient with diabetes will only spend approximately 45 to 90 min with a health care professionals(HCP).This could be two to four appointments of 10-30 min each,rest of the 8764.5 h in the year the patient has to self-manage (personal data based on clinic survey).

Care planning is not only being implemented across different countries but also across different specialties.Though care planning can be distinguished in terms for the conditions or for the patients,in usual practice it is most often for a condition-specific basis[5].The care planning content can reflect the perspective of health professional or patient,the extent of the plan to which the behaviour change is intended,and the spread of the plan (i.e.involving only doctor-patient or involving doctor-patientmultidisciplinary teams/social teams)[7].Care planning also involves behaviour change and subsequent other techniques to sustain those behaviour changes[8].Care plans are considered to be one of the best tools for standardisation of care processes[5].Prompts on electronic records such as those used in general practice in United Kingdom also serve this purpose.

Evidence for multi-factorial intervention

Rawshaniet al[9]investigated the increased risk of cardiovascular events and mortality in type 2 diabetes patients in comparison to general population[9].This study was conducted on 271174 patients with type 2 diabetes from the Swedish National Diabetes Register who were matched with 1355870 controls without diabetes.The strongest predictors for combined cardiovascular outcomes and death were- current smoking,blood pressure (BP) ≥ 140/80 mmHg,low-density lipoprotein ≥ 2.5 mmol/L,albuminuria (micro or macro),HbA1c ≥ 53 mmol/mol.Each of these five factors increased the risk of acute myocardial infarction,stroke,heart failure and mortality in patients with diabetes.The more the number of these risk factors present in a patient with diabetes,the higher was the risk observed for both unfavourable cardiovascular outcomes and mortality in comparison to the control group.This study reflects that multifactorial intervention in patients with diabetes may strongly impact in not only decreasing the adverse cardiovascular outcomes,but also reducing the mortality in diabetic patients.In the cohort ＜ 55 years of age,the results showed that the increased risk in those with none of these five risk factorsvsthose with all 5 of the risk factors was:(1) excess mortality × 4.99; (2) excess myocardial infarction × 11.35; (3) excess stroke × 7.69; and (4) excess heart failure × 7.69.

Similar results were obtained from the follow-up Steno-2 study which recruited 160 patients with type 2 diabetes with microalbuminuria[10,11].There were two randomized groups- one group receiving conventional multifactorial treatment and other group receiving intensified target driven therapy (targets included HbA1c,fasting serum total cholesterol and triglyceride levels,systolic and diastolic BP).At the start of the initial trial both groups were similar at baseline but developed significant differences by the end,showing that the intensive therapy was better than conventional therapy in attaining the set targets.In the follow up trial,both groups had received the intensive therapy and the gap of differences was observed to be narrowed by the end of the follow-up trial.The conclusions from the entire trial suggested that there is an absolute risk reduction (ARR) of 20% for death from any cause and an ARR of 29% for cardiovascular events in the intensive therapy group.Moreover,progression of diabetic complications was significantly reduced in the intensive therapy group.

The checklist approach for patient management has been rewarding in other specialties as well.Hayneset al[12]used a two-step surgical checklist in eight hospitals eight cities in different geographical parts of the world[12].Their intervention with the checklist showed marked improvements in outcomes as reduction of major surgical complications and rate of death.

The alphabet strategy for diabetes

Our innovation in diabetes care was the “Alphabet strategy” (AS),which aimed for“simple things to be done right all the time”[13].It is a mnemonic based checklist incorporating the core diabetes care components[14]; and includes the following(Figure 1):(1) advice on lifestyle:Diet,weight,and physical activity optimisation,not smoking,safe alcohol use,appropriate infection control [and very specificallyvssevere acute respiratory syndrome coronavirus 2 (SARS-CoV-2)],nationally advised vaccinations (such as against influenza,SARS-CoV-2,pneumococcus); (2) BP:＜ 140/80 mmHg,≤ 130/80 mmHg if kidneys or eyes affected or any cardiovascular disease; (3)cholesterol and CKD prevention:Total cholesterol ≤ 4 mmol/L,screening for and treating microalbuminuria; (4) diabetes control:HbA1c ≤ 58 mmol/mol or an individualised target,avoiding hypoglycaemia and hyperglycaemia interventions (for example diabetes ketoacidosis).Individualised glucose monitoring plans; (5) eye examination:check yearly at least,with referral if indicated; (6) foot care:Daily inspection and examination by patient and yearly examination by HCP; and (7)guardian drugs:Aspirin,clopidogrel and angiotensin converting enzyme inhibitors or angiotensin receptor blockers as indicated for primary and secondary preventions of cardiovascular and renal diseases.

The first version of the AS was published in 2002[14].Since then the clinical guidance and Care Plans have been updated yearly.The strategy has proven to be adaptable and it has been relatively straight forward to adapt it to even the COVID-19 pandemic.Because of the curtailment in services during the COVID-19 pandemic we have incorporated an H for Healthcare Professional advice as follows.

Healthcare Professional advice:Especially for problems such as recurrent hypoglycaemia,recurrent diabetic keto-acidosis,difficulty accessing care (including affordability),Ramadan advice,pre-conception advice,driving and occupational advice,remission of diabetes.

The clinical impact of AS was assessed by two audits done in outpatient settings of a district level hospital in United Kingdom.The first audit involved 420 patients with diabetes who were followed over 5 years.The second audit,performed 2 years after the completion of the first audit,involved 1071 patients with diabetes.Comparison of the outcomes of the two audits showed improvement in all AS components (Table 1).An audit conducted in a low-income country (India),with 100 patients with diabetes in an outpatient clinic,also demonstrated the effectiveness of AS (Table 2).

The potential of AS was globally assessed by a survey carried out in the Global AS Implementation Audit.It involved 4537 patients from 52 centres across 32 countries.The data showed that the strategy was highly acceptable to both patients and their healthcare professionals in high,middle and lower income countries.

This new care plan was developed with the National Health Service (NHS) England and NHS Improvement West Midlands our Region Diabetes Expert Advisory Group,Right Care,and the Pharmacy Local Professional Network Chair (Figure 2).

The AS core training materials (slides,documents and videos) have been created to facilitate and disseminate the programme.The training pack distributed to individual patient groups such as Diabetes United Kingdom (Figure 3) consists of:

Patient education posters:Educate the patients about the AS overall.There is a similar poster for diabetes care for specifically during Ramadan developed with the South Asian Health Foundation (Figure 4).

Patient care plans:Empowering to know their NDA target and improve self-efficacy in attaining these.It also guides the important steps for pregnant patients to reduce complications (maternal and foetal).The main components of the care plan are as follows:(1) background information:Personal targets based on NDA,Diabetes United Kingdom 15 Healthcare Essentials,Key contacts; (2) patient’s agenda:Tick section for patients to indicate points for discussion,Questions to reflect on health status and specific goals; (3) patient’s personal agenda:Aspects of care to be documented such as BP,Cholesterol,Creatinine and Urine Albumin Creatinine Ratio,HbA1c,eye screening,feet examination,guardian drugs; (4) drugs and glucose monitoring:The HCP should advice on the dosing,frequency and side effects of any new drugs started for the patient.Advice for the patient on monitoring of blood glucose with an appropriate Glucose Testing Meter including frequency of monitoring.Patient should have Community Pharmacist review also where available; and (5) contact details:There is a list of the important contact details for the key specialists/organizations related to diabetic patient management.

One page guideline:Summary of one-page current NICE guidelines in relation to diabetes care (Figure 1) to achieve higher rates of NDA attainment and facilitate multifactorial interventions.This includes sections on Diabetes Prevention and Diabetes Remission.

Referral guidelines:Diabetes Expert Advisory group advice has been incorporated on who to refer and who not to refer (Figure 5).Clear guidelines are given by Red Amber Green on whom to refer to the specialist diabetes team from primary care and secondary care.Such advice,if implemented,has the potential to reduce hospital admissions and reduce costly complications such as amputation and end-stage renal disease.

Glucose monitoring advice and choice of meter:This has the potential to save ￡1.74 million in our region if all Clinical Commissioning Groups (CCGs) merely adopted current practice similar to the best performing CCG.Enhancement on top of this can save ￡6.3 millionperyear (NHS England and NHS Improvement-West Midlands).Our region has already saved ￡ 960000 in 12 mo.

Drug optimisation advice:Data from our region shows that adopting best practice across the region would save ￡1.65 million on one class of diabetes drugs alone,example dipeptidyl peptidase-4 inhibitors (NHS England and NHS Improvement-West Midlands modelling data).

Prevention of diabetes advice:There is 86% chance of remission in selected newly diagnosed patients.Data for this comes from the DiRECT Study[15].

Achieving diabetes care excellence through primary care team programme:This is a low cost (￡25) basic e-learning platform that covers all the main aspects of diabetes care and care planning using the AS.It is hosted by Coventry University Health Sciences Faculty.It is also incorporated into Sound Doctor’s Diabetes Education Program for patients,which is Quality Institute for Self-Management Education and Training approved.

Outcomes from the AS

Improvement in process measures:Implementation of the AS for Diabetes Care resulted in a significant (P＜ 0.05) improvement including lipid measurement,BP,HbA1c,eye and foot examinations.Using the parameters from NDA,this strategy showed 100% performance of seven of the NICE recommended processes[16].Our unit scored above average in six out of the seven categories for target care process achievement.

Table 1 Comparison of achievement of alphabet strategy components between practices of evidence-based medicine audits[10]

Table 2 Change in care process performance following implementation of the alphabet strategy in a low-resource diabetes clinic[10]

Improvement in outcome measures:The improvement rates (Table 1) were comparable to standards achieved in clinical trial setting specifically researching intensive treatment strategies like Steno-2 and The United Kingdom Prospective Diabetes Study.

Figure 2 New care plan was developed with the National Health Service England and National Health Service improvement west midlands our region diabetes expert advisory group,right care,and the pharmacy local professional network.

Patient and health care professional satisfaction:An audit conducted in 27 countries(44 Diabetes service units) showed that 91% of respondent felt that the strategy would have a positive influence on diabetes care and that it would be practical to implement,even in a non-high income country (Table 2)[13].

CONCLUSION

In United Kingdom,care planning for all patients with chronic diseases has been proposed as an agreed action plan which is best reflected by the slogan-“no decisions about me without me”[17].The 15 diabetes healthcare essentials introduced for the diabetes patients not only help in better management outcomes,but also help prevent serious future complications due to the disease[18].One of the parts of the Year of Care programme for diabetes tested the “house of care” concept,which involves care and support planning at its core surrounded and supported by all the teams,tools and management plans[19].The AS helps deliver these aspirations.The strategy is also compatible with helping implement other key national guidelines and recent changes in clinical practice[15,20-22].

AS for diabetes care is intended to improve the confidence of the person with diabetes to self-manage their condition with the aspirations and the constraints of the life they lead.We are confident that it has the great potential to reduce the morbidity and mortality due to diabetes in these most difficult of times internationally due to the COVID-19 pandemic.
