Susan Reinhardt, RN, BSNJavier Font, EMT-P, EMPT-P

Learning Objectives

Understand the physiological and psychosocial impact of obesity on your patients

Learn the biases that exist toward the morbidly obese person by healthcare and effective strategies to improve patient-caregiver communications

Discuss the importance of pre-planning in management of a complex bariatric patient

Bariatric

baros – Greek for weightbaros – Greek for weight

Bariatrics: the practice of health care relating to the treatment of obesity and

associated conditions

Definitions

Overweight ~ an excess of body weight compared to standards. This could come from muscle, bone, fat and/or water. (BMI 25-29.9)

Obesity ~ refers specifically to the abnormal

proportion of body fat. (BMI 30-40)

Morbid Obesity

>100 pounds overweight or a Body Mass Index (BMI) of 40

Morbid obesity is a complicated, multi-factorial, progressive, life-threatening, genetically-related, costly disease of excess fat storage with multiple obesity related health conditions

AddictionEnvironmental

Economics HormonalViral

Influencing Factors Environmental

Electronic culture Communities not designed for physical activity

design foster driving lack of public transportation; sidewalks

Changes in Food Fast food Higher density calories Bigger portions – Super-size culture

Food Choices Convenience Less in-home cooking Fast, easier to prepare

Family, Home, School, Work Cultural Work more, home less Parents/family/co-workers habits Desk jobs Unhealthy options

Economic Constraints Insurance coverage for obesity-prevention is

limited or not available Lack of health insurance Lower-income neighborhoods have less groceries

(less fruits/veggies) and more fast food chains Value sizing less nutritious food and higher costs

of nutritious Genetics, Physiology and Life-Stages

Family history Metabolism Hormones - ghrelin Childbearing Aging factors

Psychology Greater advertising/marketing of less nutritious

foods Body image – media, societal Diet mentality Eating to combat stress, to sooth Compulsive eating Addictive personalities Childhood trauma Post-traumatic Stress Disorder

2007 Obesity Report by Epocrates, Inc

Obesity is the last bastion of discrimination; the next civil rights hurdle

Bias, Stigma & Discrimination

Social Lazy Less Intelligent Bad person Responsible for their own

condition Imperfect body reflects

imperfect person Get what they deserve and

deserve what they get (discrimination is acceptable)

Physical/Environmental Limited healthcare

resources (Ambulances, carts, exam tables, radiology equipment, BP cuffs, etc)

Seats at theaters, conference centers, places of employment, on airplanes and buses

Toilet-shower cubicles Clothing choice and prices

What is Weight Bias?

Negative attitude affecting interactions Stereotypes leading to:

stigma rejection prejudice discrimination

Verbal, physical and relational Subtle and overt expressions

Physician Bias Physicians feel that people with obesity

Are noncompliant Are hostile Are dishonest Weak-willed Lack self control Unsuccessful Unintelligent Lazy Have poor hygiene

69% of overweight and obese women experienced bias against them by doctors and 52% the bias occurred more than once

Puhl R, Brownell KD, Obes Res 2001 Dec;9(12):788-805

Nurses Bias Noncompliance most likely reason for obese patient's

inability to lose weight 63% agreed obesity can be prevented by self-control 24% reported they are repulsed by the obese 48% felt uncomfortable caring for the obese 31% prefer not to care for the obese 24% agree that obese people are unsuccessful 24% are repulsed 22% think they are lazy 12% prefer not to touch an obese person

Puhl R, Brownell KD, Obes Res 2001 Dec;9(12):788-805

Why Care?

Consequences of Bias & Stigma

Social rejection, poor quality relationships, worse academic outcomes and lower socio-economic status

Reluctant to seek medical care Put off important preventive health services and

exams More frequent cancellation or delay in appointments Less time spent with the physician

Less intervention Less discussion More often assign negative symptoms

Puhl R, Brownell KD, Obes Res 2001 Dec;9(12):788-805

Consequences of Bias & Stigma Internalize stigma, accept negative attitudes, leading

to an increase in low self-esteem In response to stigmatizing encounters, may

interfere with weight loss attempts and cause person to eat more

Those that internalize stereotypes may be more likely to binge eat and less likely to diet

Less confidence in their ability to successfully lose weight due to self-blame

Cycle of Bias and Obesity

Puhl RM, Moss-Racusin CA, Schwartz MB. Obesity Vol. 15 No.1 January 2007

How can you make a difference?

Identify One’s Own Bias Do I make assumptions based only on weight

regarding a person’s character, intelligence, professional success, health status, or lifestyle behaviors?

Am I comfortable working with people of all shapes and sizes?

Do I give appropriate feedback to encourage healthful behavior change?

Am I sensitive to the needs and concerns of obese individuals?

Do I treat the individual or the condition?

KD Brunell and RM Puhl. AMA Virtual Mentor. 2006; 8:298-302

Ways to Increase Sensitivity Recognize the complex etiology of obesity and its

multiple contributors Recognize that many obese patients have tried to

lose weight repeatedly Be sensitive to the person’s feelings

Use empathy and compassion Provide support and encouragement Respectful and motivational communications

Watch body language Have adequate equipment and supplies available

to care for bariatric populationPuhl & Brownell, 2002

Addressing the Patient

Avoid making remarks about size

Be mindful when asking for equipment; don’t ask for the “BIG” anything in front of the patient

Ask the patient what works for them

Pre-plan

Source: Obesityhelp.com message board responses 2/04

Challenges

Delayed access to preventative and/or routine medical care means a sicker or severely compromised individual

Impact on transport time Appropriate equipment?

Transport/transfer Accurate readings or starting line Able to elevate head?

Enough lifting-power to make transfer/transport?

Impact on EMS

Personnel Additional crews to assist

Equipment Stretcher Air-powered lift system Stair chair

Ambulances Bariatric Electric winches w/automatic braking system

Finances

Possible Solutions Address concerns on the handling of patients at

various weights Identify patient-movement strategies in both

emergent and non-emergent situations Set limits on the minimum number of people

required to lift patient over specified weight Require staff to request lift assistance Consider creating a special response unit that could

be shared resource Administrators must assess their systems and

circumstances plus review finances and operations, crew configuration, share resources

10 Tips for Transporting Obese Patients

1. Always treat obese patient with dignity2. Establish a system to safely handle bariatric

transports: write protocols so crew knows what to do. Practice for these runs. Assign someone to specialize in bariatric transfers.

3. Never hurry: Even when transporting an emergency patient you must think ahead, anticipate obstacles and proactively resolve problems.

4. Locate obese patients beforehand: Preplan for future runs.

5. Evaluate patient mobility prior to transport

10 Tips for Transporting cont’d…

6. Scene assessments must be performed at receiving and destination facilities: prior to transport, check width of doors, steps, etc.

7. Vehicle placement: place ambulance so terrain works in your favor.

8. Personnel: make sure you have sufficient personnel to safely move your patient.

9. Have a back-up plan: if cot doesn’t work, have device or material to accommodate.

10. Moving from bed to cot: never use a cot that’s not designed to hold your patient’s weight. Use slide board or air mattress.

Modthan, C. JEMS.com March 2007 taken from “Handle with Care” JEMS Jan. 2002

Remember….

Morbid obesity has a complex etiology and multiple contributors, including genetics, biology, sociocultural influences, the environment, and individual behavior

Morbid obesity is a disease with significant co-morbid conditions

Planning is essential to safety Treat patient with respect and dignity
