Quality of life: Guidelines for the care of people with spina bifida

Abstract

Quality of Life (QOL) and Health-Related Quality of Life (HRQOL) are important concepts across the life span for those with spina bifida (SB). This article discusses the SB Quality of Life Healthcare Guidelines from the 2018 Spina Bifida Association’s Fourth Edition of the Guidelines for the Care of People with Spina Bifida. The focus of these QOL Guidelines was to summarize the evidence and expert opinions on how to mitigate factors that negatively impact QOL/HRQOL or enhance the factors positively related to QOL/HRQOL, the measurement of QOL/HRQOL and the gaps that need to be addressed in future research.

1. Introduction

Quality of Life is defined as “an individual’s perception of their position in life in the context of the culture and value systems in which they live and in relation to their goals, expectations and concerns” [1, 2]. Health Related Quality of Life (HRQOL) is considered a sub-domain of Quality of Life (QOL) and measures a subjective perception of the impact of a health condition and/or its treatment on the individual [3, 4, 5, 6]. HRQOL is most often multidimensional encompassing physical, emotional, social, and cognitive/occupational status. The focus of the Quality of Life Spina Bifida (SB) Guideline was to summarize the evidence and expert opinions on how to mitigate factors that negatively impact QOL/HRQOL and enhance the factors positively related to QOL/HRQOL.

The measurement and study of QOL and HRQOL in SB are early in development. The rigor of most studies addressing these concepts is limited by: (a) sample size, diversity and response rate of participants, (b) measures that may not capture all domains of HRQOL and (c) measures that lack sensitivity to capture changes in QOL or HRQOL or (d) those which fail to reflect cultural differences [3, 7]. Thus, the evidence that follows is preliminary and may be incomplete but summarizes the current state of the literature at the time that these guidelines were created.

QOL/HRQOL should be measured by condition and age-related instruments. The perceptions of both the parent and child/adolescent should be measured and the child’s perception valued [3, 7]. Parent report is often but not always lower than child/adolescent report [8, 9]; children as young as eight can report on their QOL/HRQOL [10]. Use of HRQOL measures has been found useful in other chronic health conditions [7, 11]. New age and SB-specific HRQOL instruments have been recently created (QUALAS-C, QUALAS-T, QUALAS-A) but have not been used extensively [8, 9]. If time is limited, the adolescent self-report should preferentially be used over parent report.

When deciding on an instrument to use to measure QOL/HRQOL, it should be understood that some QOL measures and most HRQOL measures equate the ability to function to QOL/HRQOL such that any individual with a disability will have, by nature of the questionnaire, lower HRQOL than peers without disabilities. This conceptual equation devalues the lives of people with disabilities by automatically declaring that a person with a disability cannot have as good a quality of life as someone without disabilities. Measures that capture the individual’s perception of how their condition (i.e., spina bifida) impacts their life are preferred [12]. The World Health Organization Quality of Life (WHOQOL) Brief avoids measuring function by using items addressing perceived energy to do physical activities important to the individual [13]. Similarly, new SB and age specific measures address perception (e.g. bother, worry), not function [8, 9].

Findings regarding the impact of SB on other domains of QOL/HRQOL (social, emotional, cognitive/school/work) for children, adolescents and adults are inconsistent [3], although one review of qualitative studies indicated more issues in the psychosocial domain of QOL than physical domain [6, 14]. Evidence indicates most SB factors (e.g. level of lesion, severity of SB, ambulation) have generally had no or small associations with youth report QOL/HRQOL and only a modest relationship to parent report of generic QOL [3, 7, 15, 16, 17, 18]. However, pressure ulcers and bladder infections were related to HRQOL in one study [19]. These relationships were most often seen in function-based instruments. In adults, there was some evidence that level of lesion, full time wheelchair use, latex allergy and hydrocephalus were associated with reduced HRQOL [19, 20, 21, 22, 23, 24, 25]. However, pain has consistently been related to reduced HRQOL in all ages, by both parent and self-report and across varied instruments [7, 26].

Evidence consistently supports that bowel incontinence is associated with lower HRQOL and satisfaction with a bowel program is associated with higher HRQOL [16, 25, 27]. Data on the relationship of bladder incontinence to QOL in children is inconsistent, but studies of adolescents and adults report that support for urinary continence contributes to overall HRQOL [28, 29, 30, 31]. Using a new instrument (QUALAS-A) that specifically measures the impact of continence on adult HRQOL [8], any bowel continence and the amount, but not frequency, of urinary incontinence were related to the “Bladder and Bowel HRQOL subscale” but not to the “Health/Relationship or Esteem/Sexuality HRQOL subscales” [32]. There is little literature on sexuality and QOL, and using generic measures there was no relationship [33]. In studies to date, scoliosis status [34, 35] has not been related to HRQOL. Only one study found obesity related to HRQOL in SB where as several found no relationship [36, 37, 38]. In contrast, obesity was related to HRQOL in typically developing children and those with other chronic health conditions [24, 36, 37, 38].

Questions that Informed the quality of life guidelines

Age group	Clinical questions
0–11 months	What factors are related to QOL?
1–2 years 11 months	What factors are related to QOL?
3–5 years 11 months	What factors are related to QOL? What measures of QOL/HRQOL are the most efficient and useful?
6–12 years 11 months	What factors are related to QOL? What might QOL assessment and improvement activities look like in clinical practice? What measures of QOL and HRQOL are the most efficient and useful?
13–17 years 11 months	What factors are related to QOL? What might QOL assessment and improvement activities look like in clinical practice? What measures of QOL and HRQOL are the most efficient and useful?
18+ years	What factors are related to QOL? What might QOL assessment and improvement activities look like in clinical practice? What measures of QOL and HRQOL are the most efficient and useful?

Variables such as resilience (e.g., attitude towards SB, hope and future expectations, coping skills) have been strongly related to higher HRQOL and QOL [16, 17, 39]. In contrast, depression, a lack of optimism, and reduced executive functioning were related to lower QOL/HRQOL [13]. Similarly, family variables such as higher family satisfaction and family resources have been related to higher QOL for adolescents and those over 18 years of age [13, 16, 17]. In order to foster QOL/HRQOL clinicians should develop strategies to optimize psychosocial well-being, bowel and bladder continence, and minimize the impact of pain, if present.

QOL or HRQOL should not be measured in isolation, and there may be components of HRQOL that are not measured by current instruments. If clinicians are going to address QOL they also need to address the factors important to the individual with SB and their family. An emerging concept, Family QOL (FQOL) may have usefulness in the care of individuals and families with SB [40, 41].

2. Guidelines goals and outcomes

The goals of the QOL/HRQOL were both practical and aspirational

The aspirational objective of these guidelines was:

Improve QOL across the lifespan in individuals with SB.

The secondary outcomes (specific goals) included:

Increase QOL assessments in clinical practice.

Provide health care professionals with a better understanding of QOL and HRQOL measurement, potential issues related to available tools or tool development, and other factors related to QOL or HRQOL.

The ultimate goal to address the aspirational objective was:

Clinicians of every specialty will integrate assessment of QOL and intervention to address QOL into clinical practice.

3. Methods

The methods for the review of the literature and development of the recommendations were designed by the executive committee of the SB guidelines work group [42]. In addition, because the search for QOL articles was inadvertently omitted from the central search process, the first author conducted a search of three databases, PubMed, CINAHL, and Psychinfo, 2000–2017 using the terms “spina bifida (myelomeningocele) and quality of life” and spina bifida (myelomeningocele) and health-related quality of life”. Forty-two articles, including three reviews, were identified that addressed these concepts. References of these publications were searched for any earlier overall QOL or HRQOL studies and six additional studies were added. In addition, select studies addressing emerging instruments were added as references. Along with expert opinion, this evidence informed the guidelines. In addition, the work group summarized the SB-specific measures HRQOL, generic QOL and HRQOL instruments, and family QOL instruments. Clinical questions were created to guide the organization of the guidelines (Table 1). The results of the 48 articles that addressed these concepts along with expert opinion informed the guidelines (Table 2).

4. Results

The quality of the studies reviewed for the guidelines were limited by the study designs, breadth of the studies reviewed and the limited variables considered and thus the recommendations need to be seen as preliminary (Table 2). There was some evidence that ambulation and LOL had small relationships to these outcomes but the relationships were most often to physical domains in instruments that measured function such as ability to walk. There was consistent evidence for both pain and incontinence, especially bowel incontinence, as important factors in QOL and HRQOL outcomes. In addition, psychosocial protective factors were also strongly related to these outcomes. Strategies that support family functioning, assist children and families in their efforts to develop protective beliefs (hope, attitudes, future expectations, active coping strategies), and optimize peer relationships were reported.

In addition, as the guidelines include recommendations for use of QOL and HRQOL instruments, the work group summarized and assessed generic QOL instruments, generic HRQOL instruments, SB-specific HRQOL instruments, and family QOL instruments and their potential use in the population with SB (Table 3). The critique used criteria developed by Waters et al. [4] but was expanded to include instruments developed since their original 2009 publication.

5. Discussion

QOL and HRQOL are important concepts that health care providers working with individuals and their families need to address across the life span. Central to understanding QOL/HRQOL in individuals with SB is the accurate measurement of these important demographic, clinical and protective variables. To date, several instruments used in the assessment of QOL and HRQOL have an inherent bias, measuring function and not perception. It is critical for individuals with SB that these concepts be understood and perception-based rather than function-based instruments used. The individuals’ perceptions of the impact of the disability on their QOL/HRQOL, not the disability itself, is the central issue. Historical instruments used in the SB population have other limitations such as ceiling effects; and lack of reliability and validity data [3, 7]. Emerging instruments address these limitations and make it possible to measure self and parent reports of QOL or HRQOL. However, if only one perspective can be collected, the

Needs more psychometric evaluation before broad use.
QoL survey for people with a disability [74]. Self-report survey reduced to 30 items used for psychometric analysis	Goal was to develop a questionnaire to assess the impact of disability on QOL.

Should avoid physical scale that addresses specific tasks (vigorous activities, running, and heavy lifting). Community participation scale may be useful. Activities scale would be more useful if stated in a positive manner (what the individual can do rather than focus on limitations). Instrument developed from other instruments. Preliminary psychometrics. No involvement of individuals or family members. Many items in article are useful and worth reviewing for those addressing transition.

For comprehensive assessment of generic QOL/HRQOL measures used in Spina Bifida see Bakaniene, et al., 2016; Sawin and Bellin, 2010, and Waters et al., 2009 [3, 4, 7].

individual’s perception of their own QOL should have priority [3, 7]. Critically important for all instruments are stability or test-retest reliability. Without this data, investigators cannot tell if changes in QOL/HRQOL measured by investigators are true changes or lack of reliability in the instrument. A set of age and SB-specific instruments that measure perception-based HRQOL have been developed and show promise for future use [8, 9, 43]. These child, teen, and adult instruments have established reliability and validity including test-retest reliability and minimally important differences (MID) for clinical use. The MID for child’s subscale “Esteem and Independence” and adult’s subscale “Health and Relationships” is equal to or $>$ 10. For all the other subscales in all 3 ages the MID is equal to or $>$ 15.

In addition the WHO-BRIEF, a generic instrument, offers a perception-based assessment of QOL for adults. The strengths and limitations of each of these instruments are addressed in Table 3. There was not enough experience with the concept or the tools to include FQOL in the guidelines but future investigation is warranted. Clinicians and researchers need to carefully review available instruments to determine which give them the information they are seeking.

Once measurement issues are addressed, better understanding the factors related to QOL/HRQOL becomes a priority. To date evidence would suggest that pain, specific continence issues, and select psychosocial variables are key [3, 7]. Early interventions to address constipation and optimize bowel program effectiveness is important. Pain needs to be consistently assessed and addressed. .Much of the evidence reviewed was identified from investigations of older children, teens, and adults. However, addressing the issues identified needs to begin early and be repeated often [44]. For example, addressing constipation and bowel continence early and developing an effective bowel program in toddlers can prevent bowel incontinence which has a major negative impact on child, teen and adult QOL/HRQOL. However, because of the multiple complex medical issues that arise early, many families and providers do not appreciate the priority of addressing a bowel program at a young age.

Evaluating modifiable and social determinants of health which predict HRQOL is critical for development of future interventions [45]. Providers in SB clinics need to increase interventions to enhance psychosocial protective factors and assist youth and their families to enhance social skills [3, 7, 18, 24]. This need is particularly evident in adolescence and during the transition to adulthood [13, 18, 46, 47]. However, the building blocks for these skills are developed in earlier years. Innovative approaches to addressing these protective factors are needed as are evaluations of these approaches. In addition, during adolescence and adulthood, providers also need to consider the importance of each individual’s QOL unique priorities. For many adults, this may include satisfaction with relationships and sexuality. Finally, while care of children, adolescents and some adults occurs in SB programs, most of the care for adults occurs in the broader community. It is critical that health care professionals in these settings assess the meaning of QOL for adults and initiate actions to address the identified issues. Providers in all settings need to be aware of the “disability paradox” and “response shifts” that can occur [48, 49, 50]. A recent qualitative study of adults with an implanted, destination therapy left ventricular assist device yielded the following conceptual definition: “I am able to live my life and do what I want, with some adjustments” [51]. Determining the meaning of ‘living my life and doing what I want’ needs to be a basic assessment parameter. Then professionals can assist individuals with spina bifida to develop adjustments they need to make to meet their goals.

The development of the guidelines also identified substantial research gaps. First, there is a need for continued refinement of HRQOL and QOL measurement including the relationships between individual and parent proxy reports. Continued research is needed to better identify the factors related to QOL/HRQOL and how change in these factors across time impacts QOL/HRQOL. Especially needed is research that extends the knowledge of what role factors such as finances, ethnic identity, religion and spirituality or aging play in QOL/HRQOL. Knowledge about QOL/HRQOL in the transition to adulthood and adult health care can advance understanding of this important time [52]. In addition, it is important to determine if measuring QOL/HRQOL in clinical practice actually leads to activities that improve QOL/HRQOL. Implementation research is needed to evaluate if emerging evidence on QOL/HRQOL is integrated into practice. If the emerging evidence is not being integrated into practice, there is a need to identify and address the barriers to implementing the findings. Since the publication of the guidelines, there has been emerging evidence which, in the view of the authors, is currently shaping the dialogue relevant to these guidelines. These findings will need to be integrated into ongoing care [53, 54, 55, 56]. Finally, we need further research on the emerging concept of family QOL and its association with child outcomes.
