Experiences and barriers to Health-Related Quality of Life following liver transplantation: a qualitative analysis of the perspectives of pediatric patients and their parents
Health and Quality of Life Outcomes volume 8, Article number: 150 (2010)
This paper examines health-related quality of life (HRQOL) experiences and barriers facing young people who have received a liver transplant (LT). Semi-structured qualitative interviews were conducted with children and adolescents who have undergone LT and their parents. Findings indicate that LT fosters substantially improved child and adolescent HRQOL; however, young people also experience challenges such as difficulties with medication compliance, self-management of care routines, physical activity restrictions, and undesirable medical procedures. Implications and recommendations for clinical practice and research are discussed.
Long-term survival following orthotopic liver transplantation (LT) is now the rule rather than the exception for an increasing proportion of children with chronic or acute end-stage liver disease . Accordingly, assessment of outcomes after LT must consider not only the quantity of life years survived, but also the lived experience and quality of life for these children and their families. Early reports of improved quality of life after LT in children relied on the presence or absence of conventional outcomes such as growth, number of hospitalizations, and disease symptoms, without direct measurements of social, educational and emotional benefits or impairments . While life saving and enhancing quality of life, LT is not curative in that a fatal disease is replaced by a chronic condition that introduces morbidities such as renal dysfunction, risk of de novo malignancies, and a life-long need for immunosuppression. These challenges are reported to impose potential burden with varying severity and impact for patients and their families .
Health-related quality of life (HRQOL) has emerged as an important outcome, with increasing currency in the pediatric and rehabilitation literature. The World Health Organization defines quality of life as a state of well-being rather than merely the absence of disease . This definition invites a multi-dimensional approach that encompasses physical outcomes as well as life quality and perceived well-being. Until recently, most information about HRQOL among pediatric LT recipients has emerged from research in single centers, with relatively small sample sizes  and quantitative methodologies . However, a multi-centre study recently reported on the administration of the PedsQL™, a well-validated instrument measuring HRQOL, to 363 pediatric LT patients as well as to both a normative sample and a pediatric cancer sample . Pediatric LT patients reported significantly lower HRQOL relative to healthy children with absence from school and school functioning being areas of greatest discrepancy with healthy children. LT patient scores were comparable to cancer patients in social and school functioning ; and within other studies, pediatric LT recipients demonstrated better physical function and comparable psychosocial function relative to children with other chronic diseases [8, 9]. HRQOL in children who have undergone pediatric LT appears moderately diminished compared to children without chronic illness, including lower perceptions of general health, greater emotional impact on parents, and increased intrusion on family activities [5, 7–10].
In a multi-center analysis of HRQOL and family function in pediatric LT , parents reported significant levels of family stress, yet family function assessment scores did not yield higher levels of family dysfunction than controls . It was concluded that demographic variables may have a strong impact on family function and HRQOL . Taylor et al explored factors associated with HRQOL, using self-report measures to assess the influence of allograft morbidity and psychological and family variables on adolescent LT recipients' HRQOL . Findings suggest that age at transplant, secondary chronic illness, symptom distress, headaches, history of emotional difficulties, self-esteem and family conflict, are factors associated with adolescent HRQOL .
While these studies demonstrate increased empirical understanding of HRQOL in pediatric LT, greater knowledge is needed regarding the experiences of, and perceived facilitators and barriers to, HRQOL for pediatric LT patients and their families. The objectives of this study were to explore such elements of reported HRQOL among children and adolescents with a LT.
Qualitative interviews were conducted with young LT recipients and parents based on a 'qualitative description' approach. In qualitative description, participants' descriptive and narrative text in interviews is upheld as "a vehicle of communication" reflecting attention to the "surface of words and events" more than consideration of theoretically-driven meanings and deeper interpretations of text . This approach is relevant when relatively straight-forward description of presented phenomena is desired or likely, as in the presentation of data by young children whose developmental level may be more aligned with, or reflective of, concrete 'in the moment' description of experience.
Semi-structured interviews, each lasting approximately 0.5-1 hour, were conducted separately with children with a LT and/or a parent by a team member or research assistant experienced in qualitatively interviewing children, young people and families. Participants were interviewed in the ambulatory clinic setting or family home, at the convenience of participants; and in cases of substantial distance from the treatment hospital, participants were interviewed by telephone. Interview questions, as outlined below, addressed perceived experiences in daily life as they relate to LT and participants' perceptions of HRQOL. An interview schedule outlining open-ended questions and probes was developed following a rigorous process of literature review and pilot review of key questions from clinicians and researchers. Interviews were audio recorded and transcribed verbatim in preparation for analysis. Institutional research ethics approval was received prior to study commencement, and all participants provided written consent (and assent for those under 16 years of age) prior to study participation.

Interviews were subjected to established methods of qualitative content analysis comprising code identification, category saturation, and theme generation. A database management and computer software system for qualitative data analysis (NVivo) was utilized. A thematic analysis approach, guided by McCracken's long interview method, comprised a multi-step process of: (1) line-by-line review and code identification for salient constructs within individual transcripts, (2) identification of convergent and divergent codes across transcripts, (3) integration of codes across participant cohorts (children, parents), and (4) solidification of themes following the extensive review of the above three steps, demonstrating saturation of themes .
Trustworthiness of emerging themes, an established means for demonstrating qualitative research rigor such as credibility, auditability and fittingness , was implemented through established procedures. These procedures included negative case analysis in which the robustness of emerging themes was scrutinized by examining, within the dataset, instances of disconfirming or 'discrediting' data. Member checking, another marker of trustworthiness, was demonstrated by the review of themes by a subsample of patient and parent participants. These participants confirmed the viability of emergent themes relative to personal reflections on their own LT-related experiences. Finally, peer debriefing, comprising expert review and scrutiny of findings by key stakeholders in the field, was demonstrated. Accordingly, inter-professional clinicians with extensive experience in pediatric LT reviewed the findings and confirmed their 'fit' with clinical practice in the pediatric LT population.
The data were reviewed and coded by an analyst with extensive experience in qualitative data analysis who was further closely supervised by research team members. A sample of the data, initially reviewed by the coder and two additional 'blinded' members of the research team, achieved a high level of inter-rater reliability. Any discrepancies in codes were thoroughly examined and resolved. The data were reviewed until consensus in analysis was achieved among all coders. The primary analyst had interviewed participants at one of the data collection sites; however, was not a clinician with this population. Any potential coder bias was mitigated by an attempt to 'bracket' areas of potential coding bias, review emerging codes relative to the data, and periodic 'check ins' on the coding process by three members of the team including a qualitative methodologist.
A total of 42 pediatric patients (64% female and 36% male; average age of 12 years) and parents (84% mothers and 16% fathers) participated in qualitative interviews. All participating patients had received an isolated LT at least one year prior to study recruitment, following an earlier diagnosis most commonly of biliary atresia, acute liver failure or metabolic liver disease. They received care at a pediatric hospital in either Canada or the United Kingdom. The sample was purposively selected for diversity according to patient age, sex, cultural background, and time since transplantation. Given our data collection strategy across distinct regions (eastern Canada [Halifax], central Canada [Toronto], western Canada [Edmonton], the United Kingdom [England, Wales and Scotland] and Eire), the sample comprised diversity in region and health system, including available resources at the treatment center.
Four broad areas of thematic focus emerged: (1) LT as a facilitator of HRQOL, (2) barriers to HRQOL, (3) youth-specific perspectives, and (4) parent-specific perspectives. Each of these areas is discussed below.
1. LT as a Facilitator of HRQOL
LT was found to benefit children and adolescents in the areas of health, physical activity, relationships and overall HRQOL (Table 1). A majority of participants (59% of parents and children) reported no or few current problems with LT recipients' health. A high percentage of parents (70% of mothers and 72% of fathers) reported increased HRQOL for their child since transplantation, and 13% reported no change in HRQOL. Seventy one percent of participants reported that the child with a LT typically was physically active while 29% of children had limitations in sports-related activities. A total of 64% of participants reported that children with a LT had normal relationships with friends while only 9% reported difficulties for the child or adolescent in forming or maintaining friendships.
2. Barriers to HRQOL
While recognizing substantial benefits, LT was described to also introduce challenges in daily life, with key areas of concern noted in adherence and self management of care, physical activity restriction, impact on activities of daily living, and difficult medical procedures (Table 2). Similar in proportion to the number of parent participants recognizing post LT gains in HRQOL, the majority of parents also identified worries concerning the health of their child, and many participants reported some form of medical complication in the first year post LT and/or medication side effects over time.
In varying degrees, participants associated LT with health challenges, difficult procedures, lifestyle restrictions, and pain. They discussed the importance of pursuing health-promoting behaviors such as maintaining a healthy diet, consistency of medication administration, and exercise. Although participants recognized the importance of a healthy lifestyle, maintaining these routines was an ongoing struggle for some. Children aimed to remain healthy, yet simultaneously grappled with consequences of LT such as post-transplant complications, difficulties with medical compliance, the inconvenience of clinic visits, unwanted procedures (e.g., blood work), and worries about their health in the future.
Reflecting on barriers to HRQOL, areas of consistency and difference emerged in child and parent cohorts. Below is a discussion of these considerations, first from the vantage point of children and then from the perspective of their parents.
3. Child and Adolescent Perspectives
Children and adolescents with a LT reported multiple concerns in several domains of daily life, including substantial difficulty complying with health care requirements (such as clinic attendance, bloodwork and procedures), an intense fear of needles and bloodwork, complications after transplant (such as infection, pneumonia, rejection, septic shock, exhaustion, excessive bleeding, chicken pox, ear or dental problems, surgeries such as tonsils, adenoids, gall bladder, spleen removal and scar repair), and worry about the need for future medical procedures (such as a liver biopsy or CT scan).
Several children and adolescents described being restricted in sports-related activity. For example, they described wanting to play on a sports team at school, but were unable reportedly due to concern about risk of injury to the transplanted liver. Of further concern regarding health management, many children expressed concern about the difficulty to remember to take their medications, and some identified being inconvenienced and frustrated as a result of having to take medications on a daily basis.
Participants described bothersome side effects of medications including cushingoid features, dental problems, weight issues, excessive bleeding, high blood pressure, infection, low self esteem, mood swings, excess hair, kidney problems, swollen gums and osteoporosis. These challenges were reported to negatively impact on children's sense of comfort and view of self, with several children developing problematic behaviors such as unhealthy eating or excessive dieting.
Some children and adolescents described elements of shame, distaste and/or embarrassment about their post-surgical scar. For several, this concern reportedly did not ease over time, but rather become more pronounced in adolescence.
In terms of their families, several children described parental worries related to the child's health and future. While they identified these worries less frequently with the passage of time from transplantation, these findings illustrate children's awareness of and sensitivity to their parents' concerns, fears and anxieties. For some children, this vicarious knowledge of parental worry induced sadness and self-blame for imposing worry upon family members.
Beyond health functioning, children reported concern over absenteeism from school due to LT care, follow-up and medical complications. While some did not view missed school as a negative outcome in terms of compromised academic achievement, children consistently missed the social aspects of school-based relationships with peers.
4. Parent Perspectives
While recognizing monumental HRQOL gains due to the LT, parents identified several concerns associated with their child's ongoing LT care. Despite some agreement between mothers and fathers about specific domains of children's HRQOL, there was also diversity in expressed concerns and priority of need. In terms of agreement, the majority of mothers (87%) and all fathers reported worries about infection risk, potential for rejection, and the possible need for re-transplantation.
Parents also worried about medication side effects, child compliance with heath care regimens, and potentially needed procedures. The first year after transplantation was consistently noted by parents to be most critical and worrisome. The majority of parents stated that over time, children had less difficulty with medical compliance such as taking medication, attending clinic visits, having blood work and complying with other medical procedures. However, 36% of parents described negative aspects of medical compliance, with blood work considered to be the most difficult procedure required for medical maintenance (28%).
Parents expressed concern about potential LT impacts on their child's development and school achievement. A concern more frequently identified by mothers than fathers was children's post-operative course including transplant complications. Fathers were more frequently concerned about limitations upon children's activities of daily living such as restrictions in sports participation. Fathers' concern over sports limitations corresponded with a similar concern among several participating children and adolescents who also expressed disappointment about imposed restrictions in physical or sporting activity. While these findings raise questions of difference in priorities and perceptions between mothers and fathers, further research contrasting maternal and paternal perspectives is warranted as these differences were not the primary focus of this study. On the other hand, it is important to note that the small sample of parents participating in the study, although not representative, is reasonable given that this is an exploratory study and the qualitative research concept of saturation appeared to be achieved based on standards of qualitative rigor . While comparative trends with a larger representative sample of fathers is recommended, this study provides important exploratory findings, inclusive of both mothers and fathers, that demonstrate potential similarities and differences in parental perspective.
This study reports the qualitative experiences of pediatric LT recipients and their parents, providing new understanding of disease-specific variables and the multi-dimensionality of elements influencing HRQOL after pediatric LT. Facilitators and barriers of HRQOL were identified in the context of a desirable state of child well-being. Finally, while children's and parent's perspectives on pediatric post LT HRQOL were generally complimentary, they were not always consistent. The voices and views of children most aptly illuminated perspectives of LT; however, the inclusion of parents' perspectives added context and richness. For instance, children's perspectives tended to relate to 'here and now' elements of life lived in the moment (e.g., pain) whereas parental perspectives often reflected nuanced and more abstract elements (e.g., perceptions of the future). Ensuring children's perspectives in understanding HRQOL emerges as important [7, 10] as does the development of models for dealing with the different and perhaps shifting perspectives among children and parents.
Taillefer and colleagues identify an important challenge of bringing conceptual clarity to depictions of HRQOL, including elements, processes and outcomes . Currently, there is a lack of specificity in definitions of HRQOL, with mediators and moderators remaining unclear. In this study, we elucidated themes that contribute to or inhibit overall HRQOL rather than suggesting that these themes constitute the breadth and comprehensiveness of that quality per se. Accordingly, facilitators and barriers are identified in the context of a desirable state of child well-being, defined as health, functionality, participation in activities of daily living, and other desired outcomes of transplantation.
Pediatric LT recipients are reportedly at risk for emotional, psychological, social and school challenges [7, 17]. In a phenomenological study examining the lived experience of children 7 to 15 years of age, key themes related to pediatric LT comprised children feeling the same yet different relative to peers, considering extraordinary events such as hospitalization as ordinary and familiar, experiencing recurrent pain, parental concern and worry, and children globally viewing themselves as healthy yet normalcy being reported as, "a reality and illusion" . Taylor et al. found that most pediatric LT recipients desired normalcy and avoided distinguishing themselves as different from others . In order to achieve this normalcy a perception of wellness appears to be maintained, at times to the detriment of treatment adherence and in the hope of not being viewed as abnormal or unwell. Accordingly, the LT appears to be viewed as normal in that a routine pattern of existence is developed, yet barriers to normalcy include changed physical characteristics, medication requirements and clinic visits . Tong further identifies difficulties for young patients in redefining post-transplant identity, finding normalcy, grappling with parental overprotection, navigating social adjustment, and living with restrictions in physical activities .
Emerging models from other areas of chronic health may offer guidance. As an example, the shifting perspectives model posits an ongoing, complex reformulation in a patient's subjective health experience . Referring to this process as a continually reformulating dialectic, Paterson demonstrates that living with illness constitutes an ever-present yet ever-changing experience with illness/health elements in the foreground (e.g., feeling well) which may contradict elements that may be present in the background (e.g., critical illness requiring transplantation and vigilance in treatment adherence) . This model offers relevance and flexibility by allowing individuals to make sense of their health experience; however, the contradiction of feeling well yet needing vigilant care may impose confusion, ambivalence and health risk [21, 22].
Given the reported benefits of LT yet the simultaneous vulnerabilities to HRQOL, achieving best practice in assessment and intervention for pediatric LT recipients is critical. To that end, conceptual, empirical and evaluative advancement emerge as ongoing research priorities. It is expected that existing research with well-validated generic tools will be enhanced by the development of disease-specific HRQOL instruments based on direct input from pediatric LT recipients. Accordingly, finding effective ways to measure HRQOL and ultimately mitigate barriers and foster resilience, constitute important clinical and research priorities in the pursuit of HRQOL for LT recipients and their families.
