CASE COMPONENT
Case Introduction – Diabetes
In case FM&PH - Diabetes
Teymour Khan is a 75 year old man living in Manchester. He arrived in the UK 2 years ago from Iran, to help to look after his grandchildren. His son requires support as the children, aged 2 and 3, need looking after at home. His daughter in law unfortunately passed away in a car accident. His son works long hours as a security guard and cannot afford to employ a carer for his children. The GP supported his application to come to the UK and it has really benefited the family. Mr Khan speaks fluent Farsi but no English. He has been granted leave to remain in the UK and has full access to NHS services. He visits the GP alone and requests an interpreter to discuss his diabetes.
IN PRACTICE
What telephone interpreting services does your GP placement use?
What are the issues with using an interpreter?
In Year 4 PCC, you have had opportunity to consult with a person using a translator.
The GMC in Good Medical Practice (2013) state the importance of effective communication:
“You must give patients the information they want or need to know in a way they can understand. You should make sure that arrangements are made, wherever possible, to meet patients’ language and communication needs.”
In a systematic review by Flores (2005), 36 articles were found looking at how interpreting impacted on quality of health care. Good quality interpreting improves patient satisfaction and better care that they receive. There is a negative impact on care when there are no interpreters or poorly trained interpreters. This particularly affects patients with mental health conditions.
The barriers to good utilisation of interpreters that Flores (2005) cites include a lack of information on the cost of interpreters, lack of doctor awareness of the work of interpreters, and potential errors by interpreters. There is also a potential increase in the consultation time.

What if a family member offered to interpret?
There are several potential barriers to using a family member to interpret for a patient (Huang et al 2009):
· Confidentiality issues
· Reluctance to discuss medical problems with family present
· Family member not understanding medical terms and therefore translating wrongly
· Poor interpreting skills from interpreter, so misunderstanding the doctor’s questions
· Longer consultations as questions need to be repeated

It turns out the GP also speaks Farsi and so an interpreter is not needed. There is a medical student sitting in, who only speaks English. Mr Khan is happy for the student to sit in but they do not understand what is going on in the conversation.
How could the consultation be improved to include the student in the conversation?
Helpful guidance for medical students created by the Division of Medical Education. Please take a look at this and this can be applied in future similar consultations.
As seen in the document, there needs to be preparation before a student arrives at the practice, further clarification during induction and specific tasks undertaken during the consultation. There should also be opportunities for feedback after the consultation.
From the discussion, it appears that Mr Khan is not happy with his current prescription of Metformin as it causes him a lot of diarrhoea. He has been on the medications for 6 months and it has improved his hba1c to 78 from 87. He wants a tablet called Alogliptin as his brother is using in Iran and he has read the evidence of its impact. Mr Khan worked as a pharmacist for 40 years and is aware of the different medications he can use.
· Metformin side effects
As can be seen, diarrhoea is a common side effect of metformin. The GP will therefore need to consider an alternative tablet for the patient.
There are several options for the GP to consider. Please see: DM ADA 2019 for PCP.pdf as essential reading
Based on the NICE and GMMMG guidance, what is the most suitable medication to issue from the following list?
· Insulin
· Gliclazide
· Alogliptin
· Insulin
.Consider alternative tablets. Insulin is a later consideration in type 2 diabetes management.
· Gliclazide
.Correct answer.
Gliclazide, a sulphonylurea is selected as an alternative medication to manage his diabetes.
· Alogliptin
.Not licensed for monotherapy.

Diet and lifestyle
Mr Khan is also keen on tapping into any health services that can improve his awareness of diet and lifestyle measures to improve his health awareness. The GP is aware of an initiative led by a local charity promoting Black Minority Ethnic (BME) health, supported by the local Clinical Commissioning Group (CCG). The CCG is responsible for the allocation and utilisation of funds in primary care. This initiative is to provide health trainer input and small group workshops to improve hba1c by education on diet, weight and exercise.
The GP discusses this initiative with Mr Khan, who is keen to take part and enrols. The workshops are held in the local Iranian community centre and attended by 10 patients. Mr Khan is signposted to dietary and exercise interventions to consider. He is then provided with 6 one to one sessions with a health trainer, to improve his understanding of his condition. The dietary changes are hardest for him as he loves to eat steak and chips from the local chip shop, and also likes to eat chocolate. He enjoys the sessions as they are provided by a Farsi speaking health trainer, and also the exploration of the problems affecting his health. He has begun to attend Pilates classes, and feels this has helped with his general wellbeing.
Why would health trainers be useful in this situation?
· To provide a detailed exercise programme for Mr Khan
· To help with behaviour change for Mr Khan
· To provide an effective diet plan for Mr Khan
· To help with behaviour change for Mr Khan
.Correct answer.
Looking at this information, a health trainer would help Mr Khan in behaviour change, to reduce the intake of steak and chips and chocolate, and to eat more fresh fruit and vegetable. They will also motivate him to do more exercise.

What elements of the case would require a student to utilise cultural sensibility approaches?
Dogra et al (2003) provide a good summary of Cultural Sensibility. Sensibility refers to being able to understand the reason for something or why someone’s actions. Cultural sensibility applies this sensitivity to situations where culture is a factor. The aim is to improve medical student self-awareness, and to question their ideas on cultural issues, in order to deliver healthcare more fairly. This removes assumptions and therefore allows a student to explore issues more objectively and without bias. They also need to see a patient as an individual, and not be biased by preconceived ideas of a particular group or community.
Students should consider that Mr Khan is from Iran, but not to have any preconceived ideas about his lifestyle and diet. An example is that he likes steak and chips, rather than a traditional Iranian meal. Another example is that he enjoys Pilates classes, again not something a student may associate with a patient from the Middle East. This information would only be elicited if a student had a culturally sensible approach to the consultation.

He also sees the practice nurse to assess his general health status, checking his feet, BP and checking his BMI.
Findings:
· BP 124/78
· HR 70 regular
· BMI 27.5- overweight
· Normal tone/power/sensation feet
· He is found to have calluses on his foot and is referred to the local podiatrist for management.
Prevention
This can be divided into:
Primary prevention
“This comprises activities designed to reduce the instances of an illness in a population and thus to reduce (as far as possible) the risk of new cases appearing, and to reduce their duration.”
Secondary prevention
“This comprises activities aimed at detecting and treating pre-symptomatic disease.”
Tertiary prevention
“These are activities aimed at reducing the incidence of chronic incapacity or recurrences in a population, and thus to reduce the functional consequences of an illness, including therapy, rehabilitation techniques or interventions designed to help the patient to return to educational, family, professional, social and cultural life.”
(Boyce et al 2010; The King’s Fund: A pro-active approach. Health Promotion and Ill-health prevention. The King’s Fund)
In this case, the practice nurse is undertaking secondary prevention of a patient with Type 2 Diabetes. There should be an opportunity to sit in a Diabetes follow up clinic, and to watch the nurse perform this task. As well as the examination outlined above, she would test the urine for Urine ACR and also fasting bloods, to check lipid profile, HBA1c
What are the relevant primary, secondary and tertiary prevention measures relevant to Mr Khan?
Primary prevention in diabetes is not relevant as Mr Khan already has diabetes. Secondary care measures to prevent diabetic complications include the bloods and urine outlined, to assess glycaemic control, renal function , BP and BMI. Mr Khan will also have annual retinal screening to ensure adequate health of the eye. Tertiary measures would look at managing established complications of diabetes. This could include management of common complications, such as coronary heart disease, chronic kidney disease, glaucoma and leg ulcers.

Case Conclusion – Diabetes
In case FM&PH - Diabetes
The hba1c is rechecked and improves further to 68. Over the next 2 years, unfortunately it does not improve further despite using maximal therapy. He is therefore referred to the local diabetes nurse specialist. Insulin is commenced and this improves his diabetic control further.
CASE COMPONENT
Formative Assessment – Diabetes
In case FM&PH - Diabetes
A patient with type 2 diabetes and heart failure attends the GP surgery. He is intolerant of metformin. His GFR is 38. What would be the most appropriate choice of medicine?
· Alogliptin
· Gliclazide
· Pioglitazone
· Alogliptin
.Alogliptin dosage needs to be reduced given CKD and this will affect how well it works to reduce HBA1c.
· Gliclazide
.Correct answer.
Gliclazide is the best option as it is cheaper and can be given to patients irrespective of heart failure and CKD.
· Pioglitazone
.Pioglitazone is contraindicated in heart failure.
A 50 year old Zambian lady who has been in the UK for 30 years comes in to the surgery and mentions she has had a cough for 5 weeks. She would like treatment for this. Which investigation is not culturally sensible?
· Chest radiograph
· HIV blood test
· Sputum culture
· Chest radiograph
.Correct answer.
· HIV blood test
.Assuming that someone has underlying HIV is not culturally sensible, as it is assuming that symptoms are based on the ethnic origin of the patient. Basic tests such as chest radiograph and sputum culture can help explore the differential diagnosis, but to consider co existing HIV with T.B is an assumption too far.
· Sputum culture
.Correct answer.
Which of these is secondary prevention?
· An 80-year-old patient with diabetic nephropathy coming in to have their U+E checked
· A 48-year-old non diabetic man who comes in to have his HBA1C checked
· A 72-year-old patient with diabetes coming in to have their HBA1C checked
· An 80-year-old patient with diabetic nephropathy coming in to have their U+E checked
.This patient is tertiary prevention.
· A 48-year-old non diabetic man who comes in to have his HBA1C checked
.This patient is primary prevention.
· A 72-year-old patient with diabetes coming in to have their HBA1C checked
.Correct answer.
This patient is secondary prevention.
