Disclosures

• Financial Disclosures• None

• Off label drug use• None


Learning Objectives

• Treat chronic diseases in adults and children in resource limited settings in a rational, cost-effective way.

• Follow an income and country GNP based protocol for hypertension, type 1 and 2 diabetes, hyperlipidemia, and coronary artery disease diagnosis and care.

• Design treatment protocols based on guiding principles of cost-effectiveness.

Who has been here before…

• Asked to d/c an ill child b/c • the family is “out of money”• “they’re going to die anyway”

• Saw an elderly person in a LIC with a chronic disease and wondered if you should treat it…”Is it worth it?”

• …How to decide who to treat with what and when and how…


?Which of you would withhold treatment for a life-threatening disease if you had the medication to treat it?


Medical Missionaries Behaving Badly

• Follow US treatment protocols

• Disregard WHO or MOH country guidelines

• “We shouldn’t treat them any differently than we’d want to be treated…”

• Treating chronic diseases regardless of benefit or cost

• Expensive testing• Expensive monitoring• Expensive meds• Frequent rechecks

Cost-Effective Health Care

• Caring for people in resource limited setting• Less tests, technology, meds; just the

essentials• Less specialists• Less physician driven – lifestyle/public health

primary• Avoid futility

• Person centered, coordinated, comprehensive care by an accessible primary care provider

Tribute to Barbara Starfield, MD


Cost Effective Care

• Requires analysis of the “care delivery value chain”

• Prevention• Testing/Screening• Staging• Delaying progression of disease• Initiation of therapy• Continuous disease management• Management of deterioration

Rhatigan et al. Applying the Care Delivery Value Chain: HIV/AIDS Care in Resource Poor Setttings. Harvard Business School working paper, 2009


Cost Effectiveness Analysis

• Searches for “best buys”• E.g. smoking cessation vs statins for CVD

prevention.

• Expresses decisions in cost per benefit (usually cost in US$/DALY gained)

• Requires clear knowledge (or an informed guess) of numbers needed to treat for one to benefit

WHO and World Economic Forum, “From Burden to ‘Best Buys’”, 2009


What Is A Reasonable Cost?

Options

1.How much are they willing to pay for the estimated value of the treatment?

2.What is 1 DALY wortha. 3 x the per capita income (WHO)b. The (income of the family / # in family) x 3

(my proposal)?


Case 1:The Hypertensive Guinean Farmer

A 55 yo Guinean farmer from 2 hours away sees you for a rash on his feet. His exam reveals a BP 159/99. He is a non-smoker, mildly obese (BMI 33) man with tinea pedis but otherwise well.

a)Recommend lifestyle changes, BP checks by a VHW, treat his tinea and return if consistently elevated above 160/100.

b)Do “a” but obviously start HCTZ daily now.

c)Do “b” but check a potassium, creatinine, fasting glucose, U/A, CBC, and ECG

d)Do “c” and also check his cholesterol level and initiate statin and ASA if elevated.

e)Do “d” and also begin Metformin if diabetic.


What is HTN?JNC 7 and WHO

• Normal = systolic <120 mmHg and diastolic <80

• Pre-hypertension: systolic 120-139 or diastolic 80-89

• Hypertension:• Stage 1: systolic 140-159 or diastolic 90-99• Stage 2: systolic 160 or diastolic 100

Should we treat mild HTN?

• > 140/90 even if no risk factors?

• NNT for 1 year = 700 to prevent 1 MI or stroke related death (mild HTN).

• If cost of Rx = US$50/year, is the Guinean farmer REALLY consenting to US $35,000 to save ?10 years life (WHO suggests max cost should be 3 x per capita GNP; perhaps a better method is 3x his income or about $1300 for a Guinean farmer)?

• Paternalism vs. shared decision making.


Initial Evaluation of HTN

• Hx

• Exam

• Labs• Dip U/A; maybe other if history, exam or

urinalysis suggests need and can afford.• Creatinine• (K+)• (ECG)• (Lipids)• (Fasting blood sugar)


Who to Treat?

• WHO & JNC 7 : > 140/90 or >130/80 in renal disease

• Depends…• Access to care and follow up• Availability/cost of meds• Comorbidity• Household finances

• Risk-Based treatment with full informed consent


Wait…Are You Saying Life Isn’t Worth That?

• No…

• This is normal, of course, in US practice too…(to a far lesser degree).

• Examine the total costs per benefit.

• Where is that money coming from • Children’s nutrition• Wife’s prenatal care


Choose Meds & Methods Wisely

Start with Thiazide diuretics - cheap, few side effects• Hydrochlorthiazide 25 mg daily # 400 + 1

banana/day• “See me in 6 months” (or 1 year) – sooner if

high risk.• Annual check on co-morbidities, compliance,

refills, (dip urine).

Who to Treat?Isolated Systolic HTN?

• Systolic > 160 (Diast < 95).• NNT 5 years to prevent a major CV event

• 18 men; 38 women• 19 elderly > 70; 39 < 70 yo• 16 people with prior CV disease• So, have to treat about 20 people for 5 years to

prevent one CV event or 100 people for 1 year• NNT/year = 100• Cost to prevent an event in Africa = US$50/year

(cheapest method of treatment!) x 100 = US$5,000 to prevent a fatal MI or stroke

Second Rx:Choose Meds Wisely

• All meds ~ same benefit in large studies (ALLHAT).

• Start with Thiazide diuretics - cheap, few side effects, superior in CHD prevention

• CCB’s work best in Africans

Cost-Effectiveness Analysis

• WHO-Choice ((CHOosing Interventions that are Cost-Effective): http://www.who.int/choice/cost-effectiveness/en/

• program in the World Health Organization that helps countries decide health system priorities based on considerations of costs and impacts.

• One Health Tool – software – released 2012 http://www.who.int/choice/onehealthtool/en/

• software tool designed to inform national strategic health planning in low- and middle-income countries


Conclusion

• I can’t practice “there” just like I practice here.

• Someone has thought about what should be screened, prevented, diagnosed and treated (the WHO and MOH)

• I should integrate with national practice standards.


Case 2: The Togolese Boy With DM1

A 7 year old boy presents with DKA to your rural mission hospital. He is from a village without electricity or running water in his home. His family lives on < $2/day per person. His father comes to you as medical director of the hospital & asks you to d/c his son home to die. You would

a)Become angry and give dad your “man up” pep talk

b)Find the funds for home monitoring and insulin admin.

c)Ask the chaplain to share the Gospel with father and son and d/c him per the father’s wishes

d)Keep him hospitalized and provide continued monitoring and insulin until stable and think about it later.


DM1 – The Present Reality in LIC

• Costs exceed household resources in LIC.

• It’s a fatal disease. Life expectancy < 1 yr

• If annual treatment costs are > 2/3 the country’s per capita income, treatment is not reasonable (without relief type aid).

• International attn focused on providing specifically for DM1 costs (c.f. http://www.un-ngls.org/IMG/pdf_MDGs_and_Diabetes_Factsheet.pdf)

Case 3:The 70 year old Togolese Diabetic

A 70 yo man presents with polyuria to your rural mission hospital. He is from a village without electricity or running water. His family lives on < $2/day. You find no percussed suprapubic fullness over his bladder and a random glucose is 354. His exam is otherwise normal. You would

a)Advise weight loss, exercise, and 1 aspirin per day

b)“a” and add Metformin 2000 mg daily

c)Check a creatinine and do “b” if < 1.5

d)Do “c” and check his cholesterol and add a statin to control his LDL < 100

e)Do “d” and also add an ACE in case and recommend home glucose monitoring


Risk Reduction of Various Interventions Risk Reduction of Various Interventions - 1993- 1993

Increased cardiovascular risk in type 2 diabetes

Calculated effects of different interventions on coronary and total deaths in 1000 normal and 1000 men with type 2 diabetes aged 35 to 57 years without a history of myocardial infarction. Yudkin, JS, BMJ 1993; 306:1313


Conclusion Errors…

• The residual risk of “MRFIT” is due to high sugars

• Lowering sugar will eliminate the risk

• We should focus on frequently testing glucose and treating hyperglycemia


Value of Intensive Glycemic ControlValue of Intensive Glycemic Control3867 Type 2 DM followed 10 years3867 Type 2 DM followed 10 years

UKPDS 33, Lancet 1998

Conventional Control•Diet alone•A1C 7.9%

vs

Intensive Control•Diet + Sulfa or Insulin•A1C 7%

Less weight gain No difference in agent eff.

Less hypoglycemia 12% less laser photocoag of retinae

No sig difference in deaths

Conclusion: Tight control of DM2 doesn’t affect mortality (or help much).


ADVANCE:The End of Tight Control?

• 215 centers, 20 countries; U. of Sydney, AU

• 11,140 pts DM2 randomized to “tight” A1C 6.5% or standard A1C to 7.3%; f/u 5 years

• Age > 55, Vascular disease or risk

• No difference in CV death, nonfatal MI, stroke.

• Less macroalbuminuria (9.4% vs 10.9%)

• More hypoglycemia (2.7% vs 1.5%)

The ADVANCE Collaborative Group. INTENSIVE BLOOD GLUCOSE CONTROL AND VASCULAR OUTCOMES IN PATIENTS WITH TYPE 2 DIABETES. N Engl J Med 358(24):2560, June 12, 2008


ACCORD:The End of Tight Control?

• No significant different in MI or stroke

• Intensive treatment caused• Increased all-cause mortality 5% vs 4% (P=NS)• More Hypoglycemia 16.2% vs 5.1%• More Weight gain > 10 kg 27.8% vs 14.1%

The Action to Control Cardiovascular Risk in Diabetes (ACCORD) Study Group . The EFFECTS OF INTENSIVE GLUCOSE LOWERING IN TYPE 2 DIABETES. N Engl J Med 358(24):2545, June 12, 2008


The Big Point

• Summary of 50 years of type 2 diabetes research:

• Glycemic control has only a little to do with morbidity and mortality

• Obesity, inactivity, and other bad behaviors mitigate risk

• Correcting the real problems reduce risk.


Rational CV Risk Reduction Method:

• Smoking Cessation

• Med Diet, weight loss, exercise

• ASA

• BP normalization

• Statin (not lipid lowering)

• Glycemic control of minor benefit – use for symptoms unless well resourced.

• Self testing wasteful unless on insulin

Cost Effective Care of DM2 in LIC

• One medication decreases mortality = Metformin

• Goal – Order of highest to lowest priority1. Reduce cardiac risk (see prior slide)2. Treat to reduce symptoms not A1C3. Retinal monitoring if affordable/treatment

available4. Microalbuminuria -> ACE if affordable5. Lower fasting glucose as income allows


Case 4: The Pregnant Pakistani Woman

A healthy 30 yo G2P1 with an uncomplicated last pregnancy delivered by trained TBA in her home presents for prenatal care to your rural hospital at 12 weeks GA. You would

a)Recommend monthly visits increasing to every 2 weeks at term with hospital delivery to be safest

b)Recommend she simply again deliver at home with the TBA

c)Recommend care at the maternity in town

d)Recommend TT2, iron/folate, insecticide treated bednet use, IPTp, a prenatal visit in each trimester with a midwife or physician and delivery with the midwife.
