Therapy for A.L.L. requires a prolonged “maintenance” phase Daily oral chemotherapy Administered at home for ~ 2 years
Non-adherence to oral chemotherapy is a clinically prevalent problem

Adherence to Therapy
May be influenced by many factors: Complexity of medication regimen Duration of therapy Medication side effects Psychological and cognitive factors Family structure/dynamics Health beliefs Cultural beliefs Socioeconomic status Communication with/trust in healthcare providers
May include language barriers

Specific Aims
Develop and validate a grounded theory-based model to explain the reasons for non-adherence to oral maintenance chemotherapy in Hispanic youth with A.L.L.
Identify culturally-relevant and acceptable interventional strategies to improve adherence in this group
![Page 8: Wendy Landier, MSN, RN, CPNP (COH) Cynthia Hughes, EdD, RN (CSULA)](https://reader035.vdocument.in/reader035/viewer/2022062808/568152b4550346895dc0d700/html5/thumbnails/8.jpg)
Methods
Qualitative (inductive)
Grounded theory Methods of Strauss & Corbin
Designed to examine the process of adherence (and hence the barriers and facilitators)
![Page 9: Wendy Landier, MSN, RN, CPNP (COH) Cynthia Hughes, EdD, RN (CSULA)](https://reader035.vdocument.in/reader035/viewer/2022062808/568152b4550346895dc0d700/html5/thumbnails/9.jpg)
Eligibility Criteria Diagnosis of A.L.L. within the past 10 years at age 21
or younger (and parent/caregiver of patient meeting inclusion criteria)
Treated at City of Hope Hispanic or Caucasian Received at least one year of maintenance
chemotherapy Has now completed therapy for A.L.L. English or Spanish speaking > 12 years old to participate in interview (if <12,
parent/caregiver interviewed alone)

Analysis:Initial Results
![Page 18: Wendy Landier, MSN, RN, CPNP (COH) Cynthia Hughes, EdD, RN (CSULA)](https://reader035.vdocument.in/reader035/viewer/2022062808/568152b4550346895dc0d700/html5/thumbnails/18.jpg)
Findings: Teens/Young Adults
Phases involved in process of becoming adherent:
1. Getting sick (leukemia diagnosis)
2. Figuring it out (becoming adherent)
3. Achieving/maintaining adherence
![Page 19: Wendy Landier, MSN, RN, CPNP (COH) Cynthia Hughes, EdD, RN (CSULA)](https://reader035.vdocument.in/reader035/viewer/2022062808/568152b4550346895dc0d700/html5/thumbnails/19.jpg)
Phase 1: Themes associated with“Getting Sick”
Lack of knowledge about leukemia and its treatment
Recognition that illness is life-threatening Loss of control Dealing with emotions
![Page 20: Wendy Landier, MSN, RN, CPNP (COH) Cynthia Hughes, EdD, RN (CSULA)](https://reader035.vdocument.in/reader035/viewer/2022062808/568152b4550346895dc0d700/html5/thumbnails/20.jpg)
Phase 1: Examples of themes associated with “Getting Sick”
“You know, I mean – twelve years old – you’re not gonna know much about cancer. And it’s just like ‘Okay.’ You’ve heard of it, and you know, it’s just like, ‘What is it? How serious is this?’”
- 19 year old Caucasian male diagnosed at age 12
Lack of knowledge about leukemia and its treatment
![Page 21: Wendy Landier, MSN, RN, CPNP (COH) Cynthia Hughes, EdD, RN (CSULA)](https://reader035.vdocument.in/reader035/viewer/2022062808/568152b4550346895dc0d700/html5/thumbnails/21.jpg)
“When I first got diagnosed I mean I heard ‘cancer’ and I got a little scared . . . just seeing people with cancer and some people dying – it could happen to me and stuff at a young age – so I got a little scared.” - 21 year old Hispanic male diagnosed at age 17
Recognition that illness is life-threatening
Phase 1: Examples of themes associated with “Getting Sick”
![Page 22: Wendy Landier, MSN, RN, CPNP (COH) Cynthia Hughes, EdD, RN (CSULA)](https://reader035.vdocument.in/reader035/viewer/2022062808/568152b4550346895dc0d700/html5/thumbnails/22.jpg)
Phase 2: Themes associated with“Figuring it Out”
Learning about disease/treatment Forming alliances Taking an active role in treatment Mastering specific skills (e.g., pill-swallowing,
organization) Overcoming challenges/barriers (e.g., side
effects, forgetfulness, interference with normal activities)
Having sources of support
![Page 23: Wendy Landier, MSN, RN, CPNP (COH) Cynthia Hughes, EdD, RN (CSULA)](https://reader035.vdocument.in/reader035/viewer/2022062808/568152b4550346895dc0d700/html5/thumbnails/23.jpg)
“And the way I’d take ‘em was . . . every day at a certain time. So I would never pass that time.”
- 19 year old Hispanic male diagnosed at age 13
Mastering specific skills: Organization
Phase 2: Examples of themes associated with “Figuring it Out”
![Page 24: Wendy Landier, MSN, RN, CPNP (COH) Cynthia Hughes, EdD, RN (CSULA)](https://reader035.vdocument.in/reader035/viewer/2022062808/568152b4550346895dc0d700/html5/thumbnails/24.jpg)
“Cuz a lot of them tasted really nasty, and you would get this . . . metallic aftertaste, and it was the grossest thing ever. And so the gel caps really helped, because it takes the taste away and it’s easier to swallow.”
- 18 year old Caucasian female diagnosed at age 11
Overcoming challenges: Poor palatability of meds
Phase 2: Examples of themes associated with “Figuring it Out”
![Page 25: Wendy Landier, MSN, RN, CPNP (COH) Cynthia Hughes, EdD, RN (CSULA)](https://reader035.vdocument.in/reader035/viewer/2022062808/568152b4550346895dc0d700/html5/thumbnails/25.jpg)
“All the encouragement from my friends and family and all that, cuz other than that I don’t think I would try. . . Cuz they kept me going and stuff saying that, you know, ‘You can do this,’ and ‘You got to get better,’ and stuff. So that really helped me a lot.”
- 21 year old Hispanic male diagnosed at age 17
Having sources of support
Phase 2: Examples of themes associated with “Figuring it Out”
![Page 26: Wendy Landier, MSN, RN, CPNP (COH) Cynthia Hughes, EdD, RN (CSULA)](https://reader035.vdocument.in/reader035/viewer/2022062808/568152b4550346895dc0d700/html5/thumbnails/26.jpg)
Phase 3: Themes associated withAchieving/Maintaining Adherence
Delineation of roles/responsibilities (“teamwork”)
Parental/caregiver vigilance Making mid-course corrections Staying motivated/“thinking positive” Getting back to normal Personal growth
![Page 27: Wendy Landier, MSN, RN, CPNP (COH) Cynthia Hughes, EdD, RN (CSULA)](https://reader035.vdocument.in/reader035/viewer/2022062808/568152b4550346895dc0d700/html5/thumbnails/27.jpg)
“Even if I didn’t forget . . . my mom would still always ask me no matter what, ‘Did you take your meds? Did you remember to take your meds?’”
- 19 year old Hispanic male diagnosed at age 13
Parental/caregiver vigilance
Examples of Themes Associated withAchieving/Maintaining Adherence

“When, you know - maintenance – things kind of start to like get back to normal little by little, by little, by little, by little . . . your hair starts to grow back and you start feeling and looking normal, and feel like yourself again.”
- 23 year old Caucasian male diagnosed at age 15

Themes associated withNon-Adherence
Not overcoming barriers Lack of teamwork/alliances Not understanding disease Not understanding treatment Taking a passive role in treatment Lack of organization Rebellion
![Page 31: Wendy Landier, MSN, RN, CPNP (COH) Cynthia Hughes, EdD, RN (CSULA)](https://reader035.vdocument.in/reader035/viewer/2022062808/568152b4550346895dc0d700/html5/thumbnails/31.jpg)

- 23 year old Hispanic male diagnosed at age 18
Rebellion
![Page 32: Wendy Landier, MSN, RN, CPNP (COH) Cynthia Hughes, EdD, RN (CSULA)](https://reader035.vdocument.in/reader035/viewer/2022062808/568152b4550346895dc0d700/html5/thumbnails/32.jpg)
“Sometimes I didn’t take ‘em I just – cuz I would get sick. And I would just wait a couple days and then take the rest of them.”
- 21 year old Hispanic male diagnosed at age 17

Theory: Working Model “Making the Connection”
Evident in all interviews with youth who described medication-taking behaviors most consistent with adherence
Not evident in interviews with youth who described medication-taking behaviors less consistent with adherence, despite the fact that all clearly articulated the life-threatening nature of their illness
Recognition of association between taking oral chemotherapy and control/cure of leukemia
![Page 34: Wendy Landier, MSN, RN, CPNP (COH) Cynthia Hughes, EdD, RN (CSULA)](https://reader035.vdocument.in/reader035/viewer/2022062808/568152b4550346895dc0d700/html5/thumbnails/34.jpg)
“Making the Connection”
“I knew that if I wanted to get better and I knew I was – that I had to take these . . . There was no way around it. I mean even if you felt fine I took them. And if you like felt sick you knew you had to take them.”
- 19 year old Caucasian male diagnosed at age 12
