Patient Behavior Change







Influencing Behavior Change in

Patients Living with HIV





1

Program Objectives



 Discuss implications of behavior and psychosocial

aspects of HIV patients and opportunities for

improvement from the perspective of the patient,

caregiver, and managed care organization (MCO)

 Define and describe approaches to stimulate

behavioral change in HIV patients, applying the

Stages of Change model

 Discuss application of behavioral change

techniques to HIV patients to improve care results









2

Behavioral Health

Change









3

Purchaser’s View of Behavioral

Health Change

 Understand and value role of behavior in

influencing health

 Do not believe they have leverage for

type and quality of services

 Limited access to health status and risk

information

 Limited use of clinical and cost-

effectiveness information when making

coverage decisions

 Limited use of NCQA and HEDIS data





NCQA = National Committee for Quality Assurance

HEDIS = Health Plan Employer Data and Information Set

4

Findings on MCO Behavioral

Health Focus

 Medical Directors believe behavioral health to be

an important determinant of health outcomes but

are unfamiliar with the evidence

 Most health plans offer some behavioral health

services, but most focus on chronic disease, not

health risk

 Current offerings are mass market, as opposed to

patient, focused behavioral health efforts

Behavior Change in HIV









6

Behavior Change in HIV: Goals





 Reduce transmission via high risk behaviors





 Improve adherence to therapy, thereby

preventing resistance and improving survival

Transmission of HIV



Primary modes of transmission

• Sexual





• Parenteral

• Intravenous drug use, needles





• Perinatal

• Mother to newborn/fetus transmission

Behavioral Challenges in HIV



 Needle-based drug users and sexual practices

are behaviorally based challenges and

potential sources of disease transmission for

HIV

 Poor adherence to treatment regimens

 High rates of comorbid psychiatric disease

 Psychosocial instability

 Poor health literacy

 Significant barriers to medical interventions

 Network of seemingly unsolvable issues

Special Challenges of Caring for

HIV Patients

 Complex array of medical, psychological, and

social challenges require strong provider-

patient relationship, multidisciplinary care

team, and frequent visits

 Stigma associated with HIV/AIDS is a critical

burden on patients requiring special attention

to confidentiality

 Providers play key role in public

health/prevention

 Establishing trust, particularly with ethnic

minorities, is critical and requires

understanding of belief structures

 Many patients have inaccurate information and

need explicit communication and education

HIV Treatment







11

Highly Active AntiRetroviral

Therapy (HAART)

 Introduced in 1995

- Combination therapy with multiple-class drugs

- Generally includes 3 to 4 drugs in 3 categories:

• Nucleoside reverse transcriptase inhibitors

(NRTIs)

• Non-nucleoside reverse transcriptase

inhibitors (NNRTIs)

• Protease inhibitors (PIs)

 HAART significantly decreases viral replication and

allows immune reconstitution to begin

Palella F et al. N Engl J Med. 1998;338(13):853-860.

HAART Adherence is Critical

 HAART regimens can fail because of lack of viral

load response or poor treatment adherence

 If doses are missed or taken improperly:

- The treatment may lose its potency

- The patient's HIV infection can rapidly become

resistant to the drugs





Missing a single dose of HAART medication

even twice a week can cause the

development of drug-resistant HIV!







Carpenter CCJ et al. JAMA. 1998;280:78-86.

Challenges for Patients

Undergoing HAART



 The complexity of HAART can pose significant

adherence hurdles

- Pill burden

• Pill characteristics (size, ease of swallowing)

• Number of total pills

- Dosing schedules

- Side effects

- Meal requirements

- Poor pharmacokinetics requiring careful

attention to timing

- Therapy is a reminder of illness



Carpenter CCJ et al. JAMA. 1998;280:78-86

Adherence in

HIV Treatment









16

Adherence to HIV Therapy is an

Area for Concern



 Nonadherent HIV patients have:

- Higher mortality rates

- Lower increases in CD4 cell count

- Increased hospitalization









Paterson D, et al Ann Intern Med 2000; 133 21-30



17

Behavioral Change in HIV and

Treatment Success

 Without a commitment to change, a patient is less

likely to be adherent to therapy





 Without adherence to HAART, likelihood of a

successful virologic outcome is diminished

Paterson Dl et al. Ann Intl Med. 2000; 133:21-30 19

Successful HIV Therapy Requires

Incredibly Rigorous Adherence



 High adherence (>95%), at least with PI-based

HAART, required for optimizing virologic outcome1

and avoidance of viral resistance



 Mid-range adherence (60–90%) associated with

greater risk of virologic failure and may increase

risk of viral resistance



 Low levels of adherence ( 6 months







34

Precontemplation Stage



 Lack of awareness, denial of risks of sexual

practices and substance abuse as a problem





 Best respond to simple information to help them

consider making a behavior change

- Alcohol use makes safe sex harder to achieve

- Drug use may increase the risk of infection

Goal Setting for Behavior Change

 Set realistic, concrete risk-reduction goals for

sexual and/or injection drug behavior risk

- "I want to start using condoms with Jim this

week”



- Encourage patients to identify barriers to risk-

reduction goals



- "You've come up with good, realistic goals that

should lower your risk substantially. Now, what

might get in the way of your meeting those

goals?"

Problem Solve the Barriers to

Behavior Change

 Barriers can include:

- Anticipated problems with negotiating condom use

with a sexual partner

- Continuing to drink and frequent bars before using

intravenously

- Acquiring condoms

 Problem solve barriers

- Encourage patients to apply some of the skills and

problem-solving strategies covered in earlier

sessions to the problems they anticipate in meeting

risk-reduction goals

Problem Solving Barriers:

Examples

 Provide specific guidelines and strategies

- Align specific strategies to risk reduction goals

• Practice assertiveness in the context of negotiating

condom use

• Use positive self-talk to counter ambivalence about

and objections to condom use

• Use a problem-solving strategy to clarify the

connection between ongoing cocaine abuse and

unsafe sexual practices

- Offer specific information and provide handouts on risk

reduction

• Harm reduction vs abstinence

• Methods of transmission of HIV, other sexually

transmitted diseases, and tuberculosis

• Risks associated with sharing injection-drug HIV

antibody testing

Problem Solving to Maximize HIV

Regimen Adherence

 Ensure appropriate duration of therapy

 Assess extent of behavior change required

 Consider amount life disruption

 Counsel on options to manage cost of regimen

- Reimbursement, status of ADAP

 HIV therapy regimen complexity requires patient

education and training

- Treatment-experienced patients now being

prescribed injection fusion inhibitor require

training





47

Subcutaneous Injection

HIV Treatment









48

Self-injection

 Can be a fusion inhibitor

- Blocks HIV from entering and infecting healthy CD4

cells

 In combination with other antiretroviral agents, is

indicated for the treatment of HIV-1 infection in

treatment-experienced patients with evidence of HIV-1

replication despite ongoing antiretroviral therapy





 This indication is based on results from 2 controlled

studies (TORO 1 and TORO 2) of 48-weeks duration

- Study participants were treatment-experienced adults;

many had advanced disease

- There are no studies in antiretroviral-naïve patients







49

Self injection Clinical Trials:

TORO 1 and TORO 2

Population

 HIV-infected patients with prior treatment experience with and/or

resistance to NRTIs, NNRTIs, and PIs

 Viral load ≥5000 copies/mL

 No entry CD4 criteria



Design

 Randomized, open-label, multi-center, international



Regimen

 Optimized background (OB) regimen of 3-5 antiretroviral agents

was constructed based on prior treatment history and baseline

genotype (GT) and phenotype (PT)

 Then patients were randomized to 2:1 to injection-based regimen

or non-injection regimen

Injection Information

Important Safety Information

Self -Injection Indication:

 Is used with other anti-HIV medicines to treat

HIV-1 infection in patients who are treatment-

experienced and have detectable viral loads even

though they are taking anti-HIV medicines. This

indication is based on results from 2 studies that

lasted 48 weeks each. Patients in the studies were

treatment-experienced adults, and many of them

had advanced HIV disease.

Important Safety Information

What are the possible side effects of self-injection?

Injection site reactions

 Injection site reactions. Almost all people get injection

site reactions. Reactions are usually mild to moderate but

occasionally may be severe. Reactions on the skin included:

itching, swelling, redness, pain or tenderness, hardened

skin, bumps. These reactions usually happen within the first

week of treatment and can happen again as you keep using

it. A reaction at one skin injection site usually lasts for less

than 7 days. Injection site reactions may be worse when

injections are given again in the same place on the body, or

when the injection is given deeper than it should be (for

example, into the muscle).If you are worried about the

reaction you are having, call your healthcare provider to help

you decide if you need medical care.

Important Safety Information



 If the injection site reaction you are having is

severe, call your healthcare provider right away. If

you have an injection site reaction, you can

discuss with your healthcare provider ways to help

the symptoms. An injection site can get infected.

It is important to follow the instructions to lower

your chances of getting an injection site infection.





 Call your healthcare provider right away if there

are signs of infection at the injection site such as

oozing, increasing heat, swelling, redness or pain.

Important Safety Information

 Pneumonia: Patients with HIV get bacterial

pneumonia more often than patients without HIV.

Patients taking injection with other HIV medicines

may get bacterial pneumonia more often than

patients not receiving injection.

 You should contact your healthcare provider right

away if you have a cough, fever or trouble

breathing. Patients are more likely to get bacterial

pneumonia if they have a low number of CD4

cells, have a high viral load, use intravenous

(injected into the vein) drugs, smoke or have had

lung disease in the past.

Important Safety Information



 Allergic reactions: Injections can cause

serious allergic reactions. Symptoms of a

serious allergic reaction can include: trouble

breathing, fever with vomiting and a skin rash,

blood in your urine, swelling of your feet





 Call your healthcare provider right away if

you get any of these symptoms.

Important Safety Information

Other side effects

 The other side effects seen in patients with their

other anti-HIV medicines: pain and numbness in

feet or legs, loss of sleep, depression, decreased

appetite, sinus problems, enlarged lymph nodes,

weight decrease, weakness or loss of strength,

muscle pain, constipation, pancreas problems.

 These are not all the side effects. Some studies is

still being in children. The safety in children under

6 years of age is not known. The side effects on r

HIV-positive children aged 6 through 16 years

were similar to those seen in adult patients.

Important Safety Information



 If you have questions about side effects, ask your

healthcare provider. Report any new or worsening

symptoms to your healthcare provider. Your

healthcare provider will tell you what to do and

may be able to help you with these side effects.





 Injections are not a cure for HIV infection or AIDS.

It does not prevent the transmission of HIV.

People taking it may still get opportunistic

infections or other conditions that can happen with

HIV infection. For these reasons it is very

important that you remain under the care of your

healthcare provider while under any treatments.
