Quality of life after esophageal replacement in children

A Narrative Review of Patient-Reported Outcome Measures and Their Application in Recent Pediatric Surgical Research: Advancing Knowledge and Offering New Perspectives to the Field

INTRODUCTION

 Patient-reported outcome measures (PROMs) can be employed in both research and clinical care to enhance our understanding of outcomes that matter to patients. This narrative review aims to describe PROM use in recent pediatric surgical research, identify and describe psychometrically robust PROMs, providing an overview of those derived from pediatric patient input, and make recommendations for future research.

MATERIALS AND METHODS

 A search was conducted to identify articles published from 2021 to August 2023 describing the availability and/or use of at least one valid or reliable PROM in children with conditions including anorectal malformations, biliary atresia, congenital diaphragmatic hernia, duodenal atresia, esophageal atresia, abdominal wall defects, Hirschsprung's disease, sacrococcygeal teratoma, and short bowel syndrome. Articles were categorized based on their objectives in applying PROMs. Psychometrically robust PROMs were identified and described.

RESULTS

 Out of the 345 articles identified, 49 met the inclusion criteria. Seventeen focused on esophageal atresia and 14 on Hirschsprung's disease. Twenty-nine PROMs were identified, with 12 deemed psychometrically robust. Seven psychometrically robust PROMs were developed using patient input in the primary item generation. Most PROMs were applied to advance understanding of conditions and/or treatment and fewer were developed or psychometrically evaluated. No PROMs were assessed for their impact or incorporated into an implementation study.

CONCLUSIONS

 This review reveals gaps in the application of PROMs in recent pediatric surgical research. Emphasis should be placed on the development and utilization of psychometrically robust PROMs, broadening the scope of covered diseases, conducting impact assessments, and evaluating implementation strategies.

The International Network on Oesophageal Atresia (INoEA) consensus guidelines on the transition of patients with oesophageal atresia-tracheoesophageal fistula

Oesophageal atresia-tracheoesophageal fistula (EA-TEF) is a common congenital digestive disease. Patients with EA-TEF face gastrointestinal, surgical, respiratory, otolaryngological, nutritional, psychological and quality of life issues in childhood, adolescence and adulthood. Although consensus guidelines exist for the management of gastrointestinal, nutritional, surgical and respiratory problems in childhood, a systematic approach to the care of these patients in adolescence, during transition to adulthood and in adulthood is currently lacking. The Transition Working Group of the International Network on Oesophageal Atresia (INoEA) was charged with the task of developing uniform evidence-based guidelines for the management of complications through the transition from adolescence into adulthood. Forty-two questions addressing the diagnosis, treatment and prognosis of gastrointestinal, surgical, respiratory, otolaryngological, nutritional, psychological and quality of life complications that patients with EA-TEF face during adolescence and after the transition to adulthood were formulated. A systematic literature search was performed based on which recommendations were made. All recommendations were discussed and finalized during consensus meetings, and the group members voted on each recommendation. Expert opinion was used when no randomized controlled trials were available to support the recommendation. The list of the 42 statements, all based on expert opinion, was voted on and agreed upon.

Establishment of a condition-specific quality-of-life questionnaire for children born with esophageal atresia aged 2-7 across 14 countries

Background

Esophageal atresia (EA) is a rare congenital anomaly characterized by a discontinuity of the esophagus. Following surgical repair, survival rates have improved dramatically the past decenniums and today exceed 90%, but the children commonly present with esophageal and respiratory morbidity. In 2018, a condition-specific quality-of-life questionnaire for children with esophageal atresia (EA) aged 2-7 in Sweden-Germany was finalized (The EA-QOL questionnaire). The study aim was to describe the evaluation of the new translations across 12 new countries in Europe, Asia, Africa, Central-and North America.

Methods

Following forward-backward translation into the new languages, the 17-item EA-QOL questionnaire was tested in cognitive debriefing interviews with parents of children with EA aged 2-7. Parents rated if each item was easy to understand (clarity) and sensitive to answer (interference with personal integrity). They could skip responding to a non-applicable/problematic item and give open comments. Predefined psychometric criteria were used; item clarity ≥80%/item sensitive to answer ≤20%/item feasibility ≤5% missing item responses. The decision to modify the translation was based on native expert, patient stakeholder, and instrument developer review, and the need for harmonization between translations.

Results

Similar to findings in the Swedish-German cognitive debriefing, the cross-cultural analysis of input from 116 parents from 12 new countries (4-14 parents, median 9 parents/country) showed that all items in the EA-QOL questionnaire fulfilled the criteria for item clarity ≥80% and sensitive to answer (ranging from 1%-4.5%), although results varied between countries. Four items had missing responses between 5.2% and 13.4%, three within the same domain and were in line with parents' explanations. Poor translations and feasibility were improved.

Conclusions

Based on parent input, the collaboration between native experts, patient stakeholders, and instrument developers, a linguistic version of the EA-QOL questionnaire for children aged 2-7 for use in and across 14 countries has been established. These efforts have set the conditions for a cross-cultural field test of the EA-QOL questionnaire and will open the doors for a new chapter in outcome research, registries, and clinical practice concerning children with EA. In the long-term, this will help increase knowledge of the disease's burden, promote patient-centeredness, exchange of information between nations, and strengthen evidence-based treatments for children born with EA.

Prevalence of Mental Health Problems, Associated Factors, and Health-Related Quality of Life in Children with Long-Gap Esophageal Atresia in Sweden

BACKGROUND

Children with long-gap esophageal atresia (LGEA) face a high risk of digestive and respiratory morbidity, but their mental health outcomes have not been investigated. We aimed to identify the prevalence of mental health problems in children with LGEA, associated factors and health-related quality of life (HRQOL).

METHODS

Twenty-six children with LGEA aged 3-17 were recruited nationwide in Sweden. One of their parents and adolescents aged 11-17 completed information on the child's mental health (Strength and Difficulties Questionnaire), generic (PedsQL 4.0) and condition-specific HRQOL (EA-QOL). Parents gave information on current child symptomatology. Mental health level was determined using validated norms; abnormal≥90 percentile/borderline≥80 percentile/normal. Elevated levels were considered borderline/abnormal. Data were analyzed using descriptives, correlation and Mann-Whitney-U test. Significance level was p < 0.05.

RESULTS

Twelve children with LGEA aged 3-17 (46%) had elevated scores of ≥1 mental health domain in parent-reports, whereas 2 adolescents (15%) in self-reports. In parent-reports, 31% of the children had elevated levels of peer relationship problems, with associated factors being child sex male (p = 0.037), airway infections (p = 0.002) and disturbed night sleep (p = 0.025). Similarly, 31% showed elevated levels of hyperactivity/inattention, and associated factors were male sex (p = 0.005), asthma (p = 0.028) and disturbed night sleep (p = 0.036). Elevated levels of emotional symptoms, seen in 20%, were related to swallowing difficulties (p = 0.038) and vomiting problems (p = 0.045). Mental health problems correlated negatively with many HRQOL domains (p < 0.05).

CONCLUSIONS

Children with LGEA risk mental health difficulties according to parent-reports, especially peer relationship problems and hyperactivity/inattention, with main risk factors being male sex, airway problems and sleep disturbances. This should be considered in follow-up care and research, particularly since their mental health problems may impair HRQOL.

Clinical outcome, quality of life, and mental health in long-gap esophageal atresia: comparison of gastric sleeve pull-up and delayed primary anastomosis

INTRODUCTION

Pediatric surgeons have yet to reach a consensus whether a gastric sleeve pull-up or delayed primary anastomosis for the treatment of esophageal atresia (EA), especially of the long-gap type (LGEA) should be performed. Thus, the aim of this study was to evaluate clinical outcome, quality of life (QoL), and mental health of patients with EA and their parents.

METHODS

Clinical outcomes of all children treated with EA from 2007 to 2021 were collected and parents of affected children were asked to participate in questionnaires regarding their Quality of Life (QoL) and their child's Health-Related Quality of Life (HRQoL), as well as mental health.

RESULTS

A total of 98 EA patients were included in the study. For analysis, the cohort was divided into two groups: (1) primary versus (2) secondary anastomosis, while the secondary anastomosis group was subdivided into (a) delayed primary anastomosis and (b) gastric sleeve pull-up and compared with each other. When comparing the secondary anastomosis group, significant differences were found between the delayed primary anastomosis and gastric sleeve pull-up group; the duration of anesthesia during anastomosis surgery (478.54 vs 328.82 min, p < 0.001), endoscopic dilatation rate (100% vs 69%, p = 0.03), cumulative time spent in intensive care (42.31 vs 94.75 days, p = 0.03) and the mortality rate (0% vs 31%, p = 0.03). HRQoL and mental health did not differ between any of the groups.

CONCLUSION

Delayed primary anastomosis or gastric sleeve pull-up appear to be similar in patients with long-gap esophageal atresia in many key aspects like leakage rate, strictures, re-fistula, tracheomalacia, recurrent infections, thrive or reflux. Moreover, HrQoL was comparable in patients with (a) gastric sleeve pull-up and (b) delayed primary anastomosis. Future studies should focus on the long-term results of either preservation or replacement of the esophagus in children.

Outcome of long gap esophageal atresia at 6 years: A prospective case control cohort study

BACKGROUND DATA

EA is the most frequent congenital esophageal malformation. Long gap EA remains a therapeutic challenge for pediatric surgeons. A case case-control prospective study from a multi-institutional national French data base was performed to assess the outcome, at age of 1 and 6 years, of long gap esophageal atresia (EA) compared with non-long gap EA/tracheo-esophageal fistula (TEF). The secondary aim was to assess whether initial treatment (delayed primary anastomosis of native esophagus vs. esophageal replacement) influenced mortality and morbidity at ages 1 and 6 years.

METHODS

A multicentric population-based prospective study was performed and included all patients who underwent EA surgery in France from January 1, 2008 to December 31, 2010. A comparative study was performed with non-long gap EA/TEF patients. Morbidity at birth, 1 year, and 6 years was assessed.

RESULTS

Thirty-one patients with long gap EA were compared with 62 non-long gap EA/TEF patients. At age 1 year, the long gap EA group had longer parenteral nutrition support and longer hospital stay and were significantly more likely to have complications both early post-operatively and before age 1 year compared with the non-long gap EA/TEF group. At 6 years, digestive complications were more frequent in long gap compared to non-long gap EA/TEF patients. Tracheomalacia was the only respiratory complication that differed between the groups. Spine deformation was less frequent in the long gap group. There were no differences between conservative and replacement groups at ages 1 and 6 years except feeding difficulties that were more common in the native esophagus group.

CONCLUSIONS

Long gap strongly influenced digestive morbidity at age 6 years.

Variability in the Reporting of Baseline Characteristics, Treatment, and Outcomes in Esophageal Atresia Publications: A Systematic Review

INTRODUCTION

 As survival rates of infants born with esophageal atresia (EA) have improved considerably, research interests are shifting from viability to morbidity and longer-term outcomes. This review aims to identify all parameters studied in recent EA research and determine variability in their reporting, utilization, and definition.

MATERIALS AND METHODS

 Following PRISMA guidelines, we performed a systematic review of literature regarding the main EA care process, published between 2015 and 2021, combining the search term "esophageal atresia" with "morbidity," "mortality," "survival," "outcome," or "complication." Described outcomes were extracted from included publications, along with study and baseline characteristics.

RESULTS

 From 209 publications that met the inclusion criteria, 731 studied parameters were extracted and categorized into patient characteristics (n = 128), treatment and care process characteristics (n = 338), and outcomes (n = 265). Ninety-two of these were reported in more than 5% of included publications. Most frequently reported characteristics were sex (85%), EA type (74%), and repair type (60%). Most frequently reported outcomes were anastomotic stricture (72%), anastomotic leakage (68%), and mortality (66%).

CONCLUSION

 This study demonstrates considerable heterogeneity of studied parameters in EA research, emphasizing the need for standardized reporting to compare results of EA research. Additionally, the identified items may help develop an informed, evidence-based consensus on outcome measurement in esophageal atresia research and standardized data collection in registries or clinical audits, thereby enabling benchmarking and comparing care between centers, regions, and countries.

Psychometric Performance of a Condition-Specific Quality-of-Life Instrument for Dutch Children Born with Esophageal Atresia

A condition-specific instrument (EA-QOL©) to assess quality of life of children born with esophageal atresia (EA) was developed in Sweden and Germany. Before implementing this in the Netherlands, we evaluated its psychometric performance in Dutch children. After Swedish−Dutch translation, cognitive debriefing was conducted with a subset of EA patients and their parents. Next, feasibility, reliability, and validity were evaluated in a nationwide field test. Cognitive debriefing confirmed the predefined concepts, although some questions were not generally applicable. Feasibility was poor to moderate. In 2-to-7-year-old children, 8/17 items had >5% missing values. In 8-to-17-year-old children, this concerned 3/24 items of the proxy-report and 5/14 items of the self-report. The internal reliability was good. The retest reliability showed good correlation. The comparison reliability between self-reports and proxy-reports was strong. The construct validity was discriminative. The convergent validity was strong for the 2-to-7-year-old proxy-report, and weak to moderate for the 8-to-17-year-old proxy-report and self-report. In conclusion, the Dutch-translated EA-QOL questionnaires showed good reliability and validity. Feasibility was likely affected by items not deemed applicable to an individual child’s situation. Computer adaptive testing could be a potential solution to customizing the questionnaire to the individual patient. Furthermore, cross-cultural validation studies and implementation-evaluation studies in different countries are needed.

Factors associated with the psychological quality of life among adolescents with rare diseases in China: a national repetitive cross-sectional study

OBJECTIVE

To explore the factors associated with the psychosocial quality of life (QoL) among adolescents with rare diseases (RDs).

METHODS

We used cross-sectional design to collect data in February 2016 and February 2018, respectively, in China through a structured questionnaire. Those included in the study were adolescents aged between 10 and 18 who had a doctor-diagnosed RD. Multivariable linear regression was used to identify the predictors associated with psychosocial QoL among adolescents with RDs.

RESULTS

The study included 737 adolescents (28.4% girls). The mean score of their psychological QoL was 43.79 (SD = 20.44). Multivariable linear regression analysis suggests that girls had a lower psychological QoL than boys (adjusted coefficient = -1.87, 95% CI = [-3.53, -0.21]); and receiving an education (adjusted coefficient = 6.53, 95% CI = [4.47, 8.33]), living with parents (adjusted coefficient = 6.45, 95% CI = [3.94, 8.97]), and physical function (adjusted coefficient = 0.53, 95% CI = [0.49, 0.56]) were positively associated with psychological QoL.

CONCLUSION

This study reveals the status of psychological QoL among adolescents with RDs. The evidence provided can increase our understanding of the factors associated with psychological QoL among adolescents with RDs and can help formulate policies and put concrete actions into practice.

Postoperative morbidity and health-related quality of life in children with delayed reconstruction of esophageal atresia: a nationwide Swedish study

BACKGROUND

In 10-15% of children with esophageal atresia (EA) delayed reconstruction of esophageal atresia (DREA) is necessary due to long-gap EA and/or prematurity/low birth weight. They represent a patient subgroup with high risk of complications. We aimed to evaluate postoperative morbidity and health-related quality of life (HRQOL) in a Swedish national cohort of children with DREA.

METHODS

Postoperative morbidity, age-specific generic HRQOL (PedsQL^™ 4.0) and condition-specific HRQOL (The EA-QOL questionnaires) in children with DREA were compared with children with EA who had primary anastomosis (PA). Factors associated with the DREA group's HRQOL scores were analyzed using Mann-Whitney U-test and Spearman's rho. Clinical data was extracted from the medical records. Significance level was p < 0.05.

RESULTS

Thirty-four out of 45 families of children with DREA were included and 30 returned the questionnaires(n = 8 children aged 2-7 years; n = 22 children aged 8-18 years). Compared to children with PA(42 children aged 2-7 years; 64 children aged 8-18 years), there were no significant differences in most early postoperative complications. At follow-up, symptom prevalence in children aged 2-7 with DREA ranged from 37.5% (heartburn) to 75% (cough). Further digestive and respiratory symptoms were present in ≥ 50%. In children aged 8-18, it ranged from 14.3% (vomiting) to 40.9% (cough), with other digestive and airway symptoms present in 19.0-27.3%. Except for chest tightness (2-7 years), there were no significant differences in symptom prevalence between children with DREA and PA, nor between their generic or condition-specific HRQOL scores (p > 0.05). More children with DREA underwent esophageal dilatations (both age groups), gastrostomy feeding (2-7 years), and antireflux treatment (8-18 years), p < 0.05. Days to hospital discharge after EA repair and a number of associated anomalies showed a strong negative correlation with HRQOL scores (2-7 years). Presence of cough, airway infection, swallowing difficulties and heartburn were associated with lower HRQOL scores (8-18 years), p < 0.05.

CONCLUSIONS

Although children with DREA need more treatments, they are not a risk group for postoperative morbidity and impaired HRQOL compared with children with PA. However, those with a long initial hospital stay, several associated anomalies and digestive or respiratory symptoms risk worse HRQOL. This is important information for clinical practice, families and patient stakeholders.

Patient-reported outcome measures in pediatric surgery - A systematic review

PURPOSE

With improved long-term survival rates, measuring the quality of surgical care has gradually shifted from clinical morbidity and mortality to patient-reported outcome measures (PROMs). Since the use of PROMs in pediatric surgery is still limited, we undertook a study to identify current PROMs, assess their characteristics, and identify gaps and areas for improvement.

METHODS

A search was conducted in eight databases from their inception until May 2021 to identify PROMs that have been used in pediatric surgical patients. PRISMA standards were followed, and screening was completed by two independent reviewers. The quality of the included studies was appraised using the AXIS and the Mixed Methods Appraisal Tool.

RESULTS

Of 8282 studies screened, 101 articles met the inclusion criteria. Most of the studies (99%) were cross-sectional. We identified 85 different PROMs among the studies, 53 being disease-specific and the rest generic. The PedsQL™ was the most frequently used tool (42 studies). Almost half of the instruments (41 studies) were not validated, and 28% were developed ad hoc for each specific study. Significantly, all PROMs encountered were standardized (consisting of pre-determined domains), with no individualized tools currently in use. The overall quality of the included studies was good.

CONCLUSIONS

PROMs are increasingly used in pediatric surgery. Disease-specific PROMs predominate the field, yet validated and especially individualized PROMs are notably absent. Future efforts are needed to develop robust tools that reflect individual patient and family needs, preferences, and values, with the aim of furthering family-centered pediatric surgical care.

Longitudinal Health Status and Quality of Life After Esophageal Atresia Repair

OBJECTIVES

To longitudinally evaluate self-reported and proxy-reported health status (HS) and quality of life (QoL) of school-aged children born with esophageal atresia (EA).

METHODS

We obtained Pediatric Quality of Life Inventory (HS) and DUX-25 (QoL) questionnaires from children born with EA between 1999 and 2011 at 8 and/or 12 years old. Children completed self-reports during neuropsychological assessments in a prospective longitudinal follow-up program. Parents filled out proxy-reports at home. Total and subscale scores were evaluated longitudinally and compared with sex-specific reference norms.

RESULTS

In total, 110 participants (62% boys) were included. Self-reported HS improved significantly between 8 and 12 years for both boys (mean difference [md] 4.35, effect size [ES] 0.54, P = 0.009) and girls (md 3.26, ES 0.63, P = 0.004). Proxy-reported HS tended to improve over time, while self-reported and proxy-reported QoL tended to decline. Self-reported HS at 8 years was below normal for both boys (md -5.44, ES -0.35, P < 0.001) and girls (md -7.61, ES -0.32, P < 0.001). Girls' self-reported QoL was below normal at 8 (md -5.00, ES -0.18, P = 0.019) and 12 years (md -10.50, ES -0.26, P = 0.001). Parents reported normal HS at both ages, whereas they rated the QoL of their daughters below normal at 12 years (md -10.00, ES -0.16, P = 0.022). All above results are total scores.

CONCLUSIONS

Self-reported and proxy-reported HS of children with EA improved between 8 and 12 years, while their QoL tended to decline. We recommend to consider HS and QoL as two separate concepts and to measure both simultaneously and longitudinally when evaluating the burden of disease.
