Trigger
Patient arrives at PCP clinic seeking medical consultation and care for a set of complaints
Narrative of Events
November, 12 – First consultation
The patient: On 12 November, Mr Adam Everyman, a 52 year old male patient known to the clinic
presented at Dr Patricia Primary’s (PCP) clinic with a set of complaints suggestive of Type 2 Diabetes
Mellitus. These signs and symptoms appeared about 3 months ago before he decided that they were
bad enough for him to seek medical help.
Clinic Nurse: The patient was escorted by the clinical nurse, Nancy Nightingale, to the examination
room where routine nursing assessments were performed, which included:
Height (5.6 feet or 170 cm), weight (215.6 pounds or 98 kg; fully clothed), waist circumference
(102.5 cm; 40.35 in)
Blood pressure measured on left upper arm with patient in sitting position (179/98; second reading
10 min later = 162/92. Patient is obese. Arm circumference=37.6cm/14.8in. A large adult cuff was
used).
Based on the height and weight, the BMI calculation (=33 [30+ = obese]) indicated that the patient
was obese. The waist circumference (102.5 cm; 40.35 in) is >50% of his height. These observations
were documented.
And the nurse also documented that the blood pressure indicated that patient was still moderately
hypertensive (sitting blood pressure is 162/92) despite the prescribed medications of a thiazide
diuretic and ACE inhibitor he is taking.
The nurse performed urine dipstix test and recorded that the result showed mild glycosuria (glucose
1+; ketone –ve; RBC –ve; albumin –ve), SG = 1024
Spot blood sugar test showed a reading of 11.7 mmol/L (210mg/dl)
PCP: The patient was next seen by Dr Primary.
A review of his medical record revealed:
Family history: biological father suffered hypercholesterolemia, hypertension. His father suffered
first acute myocardial infarction at age of 44 and died from a third attack at age of 57. No family
history of DM. No known allergy/intolerance record in his EMR. The allergy/intolerance history is
checked and confirmed.
Lifestyle/social history: Patient was a smoker (12.75 pack year [15 cigarettes per day for 17 years:
15/20 x 17]; current cigarette consumption = 5-10 cigarettes/day). Previous attempts to quit
smoking (including participation in quit smoking programs and use of nicotine patches) produced
ineffective results. He tends to smoke more when stressed.
He is a social drinker (4 standard drinks per week [1 Australian standard drink = 10gm alcohol]).
Medical history: patient was diagnosed with hypertension 6 years ago. Medication treatment:
(Telmisartan 80mg daily)
Patient indicated that occasionally skipped a dose of the anti-hypertensive medications prescription
by his PCP.
Dr Primary recorded the patient’s chief complaints, conducted a thorough physical examination
which revealed no abnormality of most body systems.
Examination of the feet revealed very mild decrease in sensation and temperature of patient’s both
feet.
Dr Primary explained to the patient that based on his presenting signs and symptoms, the spot urine
and blood sugar levels, he might be suffering from Type 2 diabetes and recorded that as a
provisional diagnosis in the medical record.
The PCP discussed with the patient and created an initial general care plan to manage his health
issues before the next visit:
Health Concern
Difficulty in weight
management
Health Goal
5-10% (of 98kg) weight loss
(milestone: 0.5kg/week)

Waist circumference <94cm

Care Activity
Diet order: low kilojoule (e.g.
5025kJ-6670kJ [1200-1600kcal]
/day); low glycaemic index; low
saturated fat; high fibre diet
Regular exercise: walking (1.5km in
15 min), jogging, riding push bike,
or swimming, e.g. for 15-30 min 3
times/week
Referral to cardiac rehabilitation
nurse to initiate smoking cessation
counselling sessions
Re-enroll in smoking cessation
program
Medication: Varenicline tartrate
days 1–3: 0.5 mg daily; days 4–7:
increase to 0.5 mg twice daily; then
1 mg twice daily from day 8 to the
end of a 12-week treatment course
Poor BP control related
to possible nonadherence to
treatments
To determine median BP to
guide medication and diet
adjustment
Potential case of Type 2
DM
To confirm/rule out that
patient has Type 2 DM

BP monitoring: patient to measure
his blood pressure twice daily at
home for a week before next
follow-up visit
 Medication education: clinic nurse
to initiate medication compliance
education sessions
Diagnostic order:




Fasting blood glucose
Oral glucose tolerance test1
HbA1c
Fasting blood lipids (cholesterol,
triglyceride, HDL, LDL)
PCP reviewed care plan with the patient, and the patient agreed with the goals and planned care
activities.
Blood pressure measurement:
 As patient is obese (BMI=33, arm circumference=37.6cm/14.8in), he is advised to use a large
adult cuff when measuring his BP
 He receives instruction from the clinic nurse on how to correctly perform the BP
measurement including: rest and relax in seated position for 10 mins2 and correct
application of the cuff
The patient fasted after dinner on 12 November and went next morning to his preferred path
laboratory for blood specimens to be taken for the ordered tests.
The results were sent back to the PCP electronically two days later.
At the meanwhile, the patient measured his blood pressure at home twice daily (morning and
evening). He recorded on a paper chart given by his PCP: the BP readings, the extremity used, cuff
size and position.
November, 19 – Follow-up visit
The patient: Mr Everyman returns to the PCP clinic in the morning of 19 November for the follow-up
consultation. He brings with him the BP observation chart that recorded the week of his blood
pressure measurement.
The nurse: Nancy Nightingale measures the patient’s body weight, waist circumference which
records a 0.3 kg decrease in weight (98kg on 12 September) with no change in waist circumference.
His blood pressure reading is: 168/92
PCP: Dr Primary reviews the patient’s clinical status and records in the EMR with updated signs and
symptoms.

She reviews the patient’s blood test results:
 Fasting blood glucose = [10.3 mmol/L]; [(185 mg/dl)]
 2 hours post glucose load (75 gm) = [13.9 mmol/L]; [(230mg/dl)]3
 The HbA1c level = 7.5% (≥ 6.5% (48 mmol/mol) = cut off for diagnosing diabetes).
 His fasting lipid profile:
 Cholesterol = [6.5 mmol/L (reference range3.9 – 5.5)]; [251.4mg/dl];
 Triglyceride = [2.9 mmol/L (reference range 0.6 – 2.0)]; [256.9mg/dl];
 HDL = [1.32 mmol/L (reference range 0.90 – 1.50)]; [51.0mg/dl]
 Total cholesterol/HDL ration = [4.9:1 (reference <3.5:1)]
Based on the clinical assessment of the patient’s signs and symptoms and the blood results, Dr
Primary confirms and informs the patient of the diagnosis of Type 2 Diabetes Mellitus and
hypercholesterolaemia. The assessment findings and new diagnoses are recorded in the patient’s
EMR.
Dr Primary reviews the patient’s 1 week blood pressure readings – the readings range from 149/82
to 182/98, the median/average reading being 158/92. The higher readings are recorded in the
morning.
Dr Primary explains to the patient that Type 2 Diabetes is a complex problem. It has implications
(risks) for his existing cardiovascular comorbidities: hypercholestrolaemia and hypertension. Both
conditions (hypertension and diabetes mellitus) must be managed carefully.
Dr Primary discusses with the patient oral anti-diabetic drugs and prescribes an extended release
biguanides (Metformin/Glucophage: 500mg daily after evening meal) with a plan to review in 2
weeks to titrate the drug dose)
She discusses with the patient the benefits of initiating a Type 2 DM care plan. The care plan could
be used to effectively monitor and manage a number of health concerns related to the diagnoses,
and to coordinate the care with other providers such as diabetic educator, dietitian, etc The patient
agrees and a care plan is created.
The PCP emphasizes the importance of adherence to anti-hypertensive medications for blood
pressure control and reduction of CVS risks especially with the addition risks arising from the newly
diagnosed DM.

There is strong evidence to support treating hypertensive persons aged 60 years or older to a BP goal of less
than 150/90 mm Hg and hypertensive persons 30 through 59 years of age to a diastolic goal of less than 90
mm Hg; however, there is insufficient evidence in hypertensive persons younger than 60 years for a systolic
goal, or in those younger than 30 years for a diastolic goal, so the panel recommends a BP of less than 140/90
mm Hg for those groups based on expert opinion. The same thresholds and goals are recommended for
hypertensive adults with diabetes or nondiabetic chronic kidney disease (CKD) as for the general hypertensive
population younger than 60 years. [JAMA. 2014;311(5):507-520. doi:10.1001/jama.2013.284427]
