The Asthma Adherence Pathway™ (AAP) seeks to improve adherence to asthma therapy and
improve therapeutic outcomes by providing adherence educational services to
patients and their families, as well as to providers and payers
How the Program Works
Healthcare payers/administrators (e.g. HMOs, Medicare/Medicaid,
self-insuring private companies, etc.) enroll in the AAP as
a means of promoting asthma treatment adherence rates and improving
the quality of life and productivity of their employees or subscribers.
Participating payers can enroll both patients (i.e.
the payers’ subscribers or employees) and healthcare providers
in the program. Enrolled parties are given codes allowing them to
enter the password-protected part of the site.
Enrolled patients, upon the recommendation of their
participating payer or provider, will go to the password-protected
site to complete an online survey of their asthma history, symptoms,
and treatment. The survey takes about ten minutes, and once
it is finished, the patient can generate a printable summary of
the issues and concerns raised. The results will also be available
online to the participating provider, who will review the survey
with the patient by appointment.
Enrolled providers can go to the password-protected
site to review the results and recommended treatment strategies
for a single patient survey. Providers can also examine the statistics
yielded by select groupings of anonymous surveys. Additionally,
providers will find that the password-protected site offers proven
guidelines and practical strategies for helping their patients agree
to and follow through with a cost-effective treatment plan.
For patients and families: The program provides an opportunity to
share concerns with healthcare providers who can use that information
to help them control symptoms and improve quality of life by following
an agreed-upon treatment program.
Physicians: The program provides a way to identify
a patient's adherence; reasons for non-adherence to asthma therapy, and efficiently
address those issues in a cost-effective manner.
Payers: The AAP program provides a disease management
tool that enables providers to accurately diagnose and treat asthma;
promotes adherence in a cost-effective manner; and reduces symptoms
and improves the quality of life and productivity of their employees
or subscribers. The AAP can also be accessed by multiple care givers or supervisers depending on the health care organization.
How To Participate
Patients or family members interested in participating in the Asthma
Adherence Pathway program should contact their healthcare
provider or their payer’s benefits administrator.

About Dr. McQuaid
Elizabeth McQuaid's served as a consultant in developing the Asthma Adherence Clinical Pathway. Her current research interests focus on the psychosocial aspects of pediatric asthma, including adherence to pediatric asthma regimens across the adolescent transition and individual and family characteristics that influence pediatric asthma outcomes. She is current PI on two treatment trials to improve asthma management among low-income children, and a longitudinal study evaluating asthma management across the transition to high school. Dr. McQuaid is currently the Director of the Brown Clinical Psychology Training Consortium.
The Asthma Adherence Pathway is a result of more than 30 years of research and clinical practice. Dr Weinstein developed the area of Asthma Adherence Disease Management which requires four sequential components to be delivered to the patient. The first is is to diagnose the adherence status of the patient. Second, if the patient is non-adherent, identify the reason(s) why. Three, select strategies that are relevant to the patient’s concerns to improve adherence. And fourth, deliver the strategy in a way that will have an optimum effect, such as using Motivational Interviewing technique or other patient-centered communication programs
The Asthma Adherence Pathway was derived from the clinical treatment model developed at the Alfred I Dupont Hospital for Children Asthma Rehabilitation Program in Wilmington Delaware. It was subsequently applied to child and adult asthma patients in clinical practice and then placed on the Asthma and Allergy Foundation of America web site www.asthmaPACT.org. The treatment model has been shown to be effective in reducing hospitalization, emergency care and costs from severe asthma.
History and Development of the Program
By Dr. Andrew Weinstein
Like many physicians, I have been engaged in a career-long pursuit to improve the health of my patients. During my first year of pediatric residency at the Children’s Hospital of Philadelphia in 1973. I began to realize that many children with chronic diseases and their parents did not follow physicians’ treatment plans.
During my first six-week inpatient rotation, an adolescent boy with hemophilia (factor 8 deficiency), was admitted twice with his ankle and knee bleeding. When I first took his history, the cause of the trauma was a touch football game in the streets of South Philadelphia. His mother, a single parent, was frustrated that her son was not following the doctor’s common sense instructions: do not play games that can cause trauma. The hematology group was very concerned that the boy had developed antibodies to the factor replacement, compromising his treatment’s efficacy. Several weeks later, he was admitted again after "going for a deep out and I ran into the curb, but I held onto the ball for a touchdown." I was told by the attending, that the situation was very frustrating for the doctors and families, but there wasn’t much anyone could do about it.
As the two years of residency passed, the words of the attending rang true. Many children with a multiplicity of chronic diseases were being readmitted because the family -- and/or the child -- were not following an "effective" treatment plan. More importantly, no one was doing anything about it. During my residency, Salvador Minuchin M.D., a family therapist and author of Families and Family Therapy, and Lester Baker M.D., a pediatrician, were examining the relationship of stress, disease response, and family interaction (psychosomatics) at the Philadelphia Child Guidance Clinic (PCGC) and the Clinical Research Center of the Children’s Hospital of Philadelphia. They theorized that certain types of family interactions in children with anorexia nervosa, diabetes, and asthma were responsible for persistent symptoms that could lead to hospital admission. (Their theory was later published in Psychosomatic Families: Anorexia Nervosa in Context.1978)
I found this work very interesting and began to chart
a career path that would include training in child psychiatry. I
arranged a third year of pediatric residency at Hahnemann Hospital,
which included six months of child psychiatry electives. Buoyed
by my continued interest, I convinced Dr. Harold Lecks, the chairman
of the allergy department at Children’s Hospital, to permit
me to combine an allergy/clinical immunology fellowship with a family
therapy training program, a once weekly evening extern program directed by Dr. Minuchin at the Child Guidance Clinic.
Dr. Minuchin's and colleagues’ family-therapy
lectures and seminars gave me a framework to understand the structure
and organization of families, spouse and child subsystems, and the
adaptive and maladaptive ways families react to chronic childhood
illness. Psychosomatic illness, including asthma, was part of the
In 1982, I conducted a pediatric asthma adherence study at the Medical
Center of Delaware’s pediatric clinic. I examined the effectiveness
of the interventions I learned during my fellowship and measured
adherence by prescribing theophylline and obtaining blood levels.
In 1985, I was asked to establish an inpatient asthma
rehabilitation program at the Alfred I. duPont Institute in Wilmington.
At that time the hospital’s goal was to become a full-service
children’s hospital, shedding its image as a world-class orthopedic
hospital for children.
The duPont Asthma Rehabilitation
Program was organized around family involvement. Family members
had to be willing to meet with our multidisciplinary team
twice weekly for their child to be admitted. The team consisted
of a pulmonologist, psychologist, social worker, gastroenterologist,
physical therapist, nurse practitioner, primary nurse, and myself
serving as allergist, clinical immunologist, and family therapist.
From the beginning of the program, the goals for admission were
to improve and maintain adherence with multiple drug and environmental
recommendations and decrease or prevent psychosomatic asthma. We
believed that nearly all asthma symptoms could be controlled if
adherence and psychosomatic issues could be addressed.
We were interested in the most severely asthmatic children and their families. Most of the children/families were treated for 10-14 days. The hospital administrator was working with managed care, being very responsive to their concerns about cost. Our group continually revised our approach, made cuts to our program, and focused on what was essential for achieving adherence and preventing stress-induced asthma.
After discharge, the children and families were seen
as outpatients with drug monitoring for adherence for most patients,
since most were receiving theophylline as one of four to seven medications
taken two to four times per day. Family sessions would continue
as needed to improve adherence and reduce psychosomatic asthma.
In all, we cared for 59 consecutive patients with unusually good results. The
median number of hospital days the year prior to admission for the
group was seven; emergency care visits four. For each of the four
years of follow-up the median number of hospital days and emergency
visits was zero. Median total costs for asthma care the year prior
to admission were $10,240. The costs during follow-up were:
- Year one $4,036
- Year two $2,801
- Year three $2,316
- Year four $1,936
These were significant savings, financially, for the
health insurers. (Journal of Allergy and Clinical Immunology 1996;
At several health plans’ requests we established a less expensive outpatient program that was designed to reduce hospitalization and emergency care but would be administered over five days. Family involvement with emphasis on adherence and psychosomatics were the key components. Eleven patients/families were treated with comparable, if not superior results, in that these children had more severe disease than the inpatient group (Journal of Allergy and Clinical Immunology 1998; 101:S178A).
What lessons might health policy makers learn from
this body of work in developing a "better" treatment style
for childhood asthma? A complete report can be found in the Final
Report of the Medication Adherence Task Force, Weinstein, et.
al (Del Med Jrl 2001; 73: 341-345), but the two most important points
can be summarized as follows:
The first is that identifying adherence status can improve health and decrease medical costs secondary to hospital care. The data from the asthma rehabilitation program supports this claim. Non-adherence with treatments is an enormous problem affecting all areas of health care. It is estimated that 50% of patients do not follow medical advice.
The second is that physicians should have psychological, family systems, and communication training during medical school and residency training to help manage patients with chronic disease. These topics have been introduced in many medical schools. "Talking" appears to be an important part of healing. Physicians should not only be knowledgeable about an individual’s health needs. They should also be able to convey this information in a manner that encourages and motivates the individual to act responsibly. Using the family conference as a means to "activate" a plan can be helpful. Health policy makers may also want to train allied health professionals (e.g., nurses, educators) to carry out these tasks at significantly lower costs. Many of these individuals might be more sympathetic and interested than some physicians. The Asthma Adherence Pathway provides a survey for patients that was successfully used in the DuPont Asthma Rehabilitation Program. What is unique about the AAP is that it provides a disease management algorithm that connects the individual and unique concerns of a patient to recommended, proven guidelines that a physician can use to maximize patient adherence and outcomes.
Improving Adherence and Reducing Costs
The human and financial costs for asthma care are considerable as mentioned above. Estimates for cost secondary to non-adherence have been as high $290 billion per year. With treatment, however, many of these costs are preventable.
EPR3 states that most asthma patients can be asymptomatic, with normal quality of life, if they take recommended anti-inflammatory medication, typically inhaled ICS.(1) But in practice, there is an unacceptably high level of preventable morbidity and mortality. Poor medication adherence (due largely to low motivation), poor inhaler technique and inadequate medication are major causes of treatment failure, but physicians have no practical tools to determine which are operative for a given patient.(2)
In out-patient studies, non-adherence rates for inhaled corticosteroids (ICS) range from 28%-56%.(3,4) Although there is no way to measure ICS adherence in patients who come to the ER due to an asthma exacerbation, most clinicians estimate that adherence is significantly lower than the outpatient findings above.(2) A 1979 study examining adherence to theophylline, a widely-used prophylactic medication of that era, found that only 2% of children had a therapeutic level when seen in the ER.(5) The investigators measured adherence with an assay used to determine therapeutic dose. This finding is consistent with studies that report only 8%-13% of patients continue to fill ICS prescriptions after one year.(3,4) Medication non-adherence is associated with increased symptoms,(6) ER visits,(7) hospitalizations(6) and use of oral steroids.(7)
One significant problem for clinicians attempting to follow EPR3 guidelines is the inability to accurately diagnose the adherence status of asthma patients.(2) Multiple studies have documented that many patients do not give a truthful report of medication use to physicians.(8,9) This is a critical problem for non-adherent (NA) patients with severe disease, since many who are not diagnosed as NA are seen in the ER and admitted to hospital and managed incorrectly, as if they were adherent, while the underlying cause of the symptoms, NA, goes unrecognized.(2) These patients are at risk for receiving excess medication, imaging, lab tests, office visits, ER visits, hospitalization and increased morbidity and mortality due to physicians? inability to diagnose the true cause of treatment failure,(2)
Increasing asthma knowledge through education yields little improvement in adherence or asthma outcomes.(10) Interventions that encourage patients to monitor symptoms or peak flow have shown significant but small effects on morbidity.(11) Self-management approaches, including identifying barriers to adherence, self-monitoring of medication, goal setting and problem solving result in fewer ER visits,(10) short-term improvements in adherence,(12,13) higher self-management self-efficacy,(14) improved QoL,(15) reduced symptoms,(12) and less beta-agonist use.(12) However, most self-management studies involved more than 5.5 hours of patient contact.(16)
The Asthma Adherence Pathway™ allows patients to self-identify barriers to adherence and report non-adherence with medication prescribed. When adherence barriers are identified, specific strategies are recommended in combination with patient-centered communications skills such as motivational interviewing. This creates a non-judgmental atmosphere in which patients are comfortable discussing their true conflicts about adherence. These strategies help patients resolve ambivalence about medication and builds their intrinsic motivation.
Dr. Weinstein has preliminary validation data for both child and adult AAPs (see pdfs). He was a co-investigator in an NIH study Grant#7R44HL078252-05 which developed a brief (11 item) Adult Asthma Adherence Questionnaire which will help clinicians both identify patient and improve adherence status.(17) Dr. Weinstein continues to use electronic adherence monitors for inhaled corticosteroids to give feedback to promote adherence.
The rationale to monitor patients with severe persistent asthma was published by Dr. Weinstein in the February 2005 Annals of Allergy, Asthma and Immunology (see PDF). Dr. Weinstein has been successfull in using the AAP and electronic monitors for patients with severe asthma referred by Blue Cross Blue Shield of Delaware. Using this comprehensive and novel method the Asthma Monitoring Project was able to reduce asthma costs by 72% (Data on file BSBSDE). The AAP is now available for all clinicians caring for child and adult patients to promote adherence, reduce morbidity, enhance quality of life and reduce costs for care.
The healthcare industry has an unusual opportunity to improve care and reduce costs with a minimal investment. Health plans will save significant sums by reducing the frequency of hospital care. Pharmaceutical companies will increase sales of their products since individuals will be taking more of them. Physicians will be more productive and achieve more satisfaction in their practice by improving healthcare outcomes. Hospitals will be more efficient and reduce unnecessary admissions. This scenario can only be realized if clinicians can diagnose the adherence status and identify reasons for non-adherence. The Asthma Adherence Pathway™ is an online monitoring tool that helps physicians to do exactly that. It enables them to identify the existence of and likely reasons for non-adherent behavior, while offering the educational information, proven guidelines, and practical strategies that will help them promote adherence to asthma treatment plans.
