Barriers to care for women with low-grade endometrial cancer and morbid obesity: a qualitative study

OBJECTIVE

Obesity is a major risk factor for low-grade endometrial cancer. The surgical management of patients with obesity is challenging, and they may face unique barriers to accessing care. We completed a qualitative study to understand the experiences of low-grade endometrial cancer patients with morbid obesity, from symptom onset to diagnosis to surgery.

DESIGN

Semi-structured interviews were performed with endometrial cancer patients with morbid obesity (body mass index (BMI) >40 kg/m²) referred for primary surgery. Transcribed interviews were coded line-by-line and analysed using an interpretive descriptive approach that drew on labelling theory to understand patients' experiences. Thematic sufficiency was confirmed after 15 interviews.

SETTING

Two tertiary care centres in Toronto, Ontario, Canada.

PARTICIPANTS

Fifteen endometrial cancer patients with a median age of 61 years (range: 50-74) and a median BMI of 50 kg/m² (range: 44-70) were interviewed.

RESULTS

Thematic analysis identified that (1) both patients and providers lack knowledge on endometrial cancer and its presenting symptoms and risk factors; (2) patients with morbid obesity are subject to stigma and poor communication in the healthcare system and (3, 4) although clinical, administrative, financial, geographic and facility-related barriers exist, quality care for patients with morbid obesity is an achievable goal.

CONCLUSIONS

Improved education on the prevention and identification of endometrial cancer is needed for both patients and providers. Delivery of cancer care to patients with morbid obesity may be improved through provider awareness of the impact of weight stigma and establishing streamlined care pathways at centres equipped to manage surgical complexity.

Benefits and burdens of newborn screening: public understanding and decision-making

In this article we review the literature regarding the public understanding of the potential benefits and burdens of expanded newborn bloodspot screening. We draw attention to broadened notions of benefit that go beyond early identification of asymptomatic individuals and interventions to reduce morbidity or mortality, and include benefits gained by families through knowledge that may facilitate life choices, as well as gains generated by avoiding diagnostic delays. We also reflect on burdens such as increasing false-positive results and parental anxiety, together with risks of overdiagnosis when the natural history of a condition is poorly understood. We conclude that expanded notions of benefit and burden bring with them implications for parental consent and confidentiality and the secondary use of bloodspots.

Obsessive-Compulsive Disorder: The Process of Parental Adaptation and Implications for Genetic Counseling

Obsessive-compulsive disorder (OCD) has primarily pediatric onset and well-documented unique impacts on family functioning. Limited research has assessed the understanding that parents of children with OCD have of the etiology of the condition, and there are no data regarding potential applications of genetic counseling for this population. We recruited 13 parents of 13 children diagnosed with OCD from the OCD Registry at British Columbia Children's Hospital, and conducted qualitative semi-structured telephone interviews to explore participants' experiences with their child's OCD, causal attributions of OCD, and perceptions of two genetic counseling vignettes. Interviews were audio-recorded, transcribed, and analyzed using elements of grounded theory qualitative methodology. Analysis revealed key components and contextual elements of the process through which parents adapt to their child's OCD. This adaptation process involved conceptualizing the meaning of OCD, navigating its impact on family dynamics, and developing effective illness management strategies. Adaptation took place against a backdrop of stigmatization and was shaped by participants' family history of mental illness and their child's specific manifestations of OCD. Parents perceived genetic counseling, as described in the vignettes, as being empowering, alleviating guilt and blame, and positively impacting treatment orientation. These data provide insight into the process of parental adaptation to pediatric OCD, and suggest that genetic counseling services for families affected by OCD may help facilitate adaptation to this illness.

Access to novel drugs and therapeutics for children and youth: Eliciting citizens' values to inform public funding decisions

INTRODUCTION

The unique evidentiary, economic and ethical challenges associated with health technology assessment (HTA) of precision therapies limit access to novel drugs and therapeutics for children and youth, for whom such challenges are amplified. We elicited citizens' perspectives about values-based criteria relevant to the assessment of paediatric precision therapies to inform the development of a child-tailored HTA framework.

METHODS

We held four citizen panels virtually in May-June 2021, informed by a plain-language citizen brief summarizing global and local evidence about the challenges, policy and programmatic options and implementation strategies related to enhancing access to precision therapies for Canadian children and youth. Panellists were recruited through a nationally representative database, medical/patient networks and social media. We inductively coded and thematically analysed panel transcripts to generate themes and identify priority values.

RESULTS

The perspectives of panellists (n = 45) coalesced into four overlapping themes, with attendant subthemes, relevant to a child-tailored HTA framework: (1) Childhood Distinctions: vulnerability, 'fair innings', future potential, family impacts; (2) Voice: agency of children and youth; lived versus no lived experience; (3) One versus Many: disease severity, rarity, equity, unmet need and (4) Health System Governance: funding, implementation inequities, effectiveness and safety. Participants broadly agreed that childhood distinctions, particularly family impacts, justify child-tailored HTA. Dissent arose over whose voice should inform HTA and how such perspectives are best incorporated.

CONCLUSIONS

Citizens can offer unique insights into criteria relevant to the development or revision of HTA frameworks to capture holistic, societally responsive dimensions of value attached to unique contexts or populations, including children. Balancing the hopes and expectations of patients and caregivers for access to expensive but potential life-altering therapies against the opportunity costs borne by encompassing health systems is a fundamental challenge that will require rigorous methods to elicit, weigh and reconcile varied views.

PATIENT OR PUBLIC CONTRIBUTION

A patient advocate served on the steering committee of this study and co-authored this article. Key informants for the Citizen Brief included patient advocates and caregivers; a separate patient advocate reviewed the Brief before dissemination. Qualitative and quantitative data were collected from the general public and caregivers of children, with written consent.

Governing population screening in an age of expansion: The case of newborn screening

Newborn bloodspot screening is one of the most enduring and successful population screening initiatives. Yet technological innovation to permit simultaneous measurement of multiple biomarkers - and potentially, entire genomes - has spurred expansion and debate. Through a cross-jurisdictional comparison, we describe the varied roles and reach of screening-related governance structures in the United States, the United Kingdom, New Zealand and Canada, and highlight the distinct values and resources brought to bear by the genetics, public health and maternal-child health communities in adjudicating the benefits and burdens of expanded newborn screening. We call for the expansion of formal governance structures that are balanced in resources and perspective and mandated to ensure that the organization and delivery of newborn screening achieves optimal quality.

Does personal genome testing drive service utilization in an adult preventive medicine clinic?

Personal genome testing (PGT) that assesses risk for common diseases may influence the use of preventive health services, but outcome data are limited. We aimed to assess health service utilization following PGT. We conducted a retrospective matched cohort study at an adult health clinic. Medical records of clients who pursued PGT at their comprehensive health assessment (CHA) over a 1-year period (N = 388) were reviewed and compared to age- and sex-matched clients who underwent CHA but not PGT (N = 388). We measured condition-specific health services used post CHA up to two subsequent visits while accounting for confounding factors (e.g., family history, health status, and age). A relatively equal number of post CHA services were used by clients who pursued PGT and those who did not pursue PGT (52% and 48%, respectively). Overall and across the majority of conditions examined, clients' service utilization was significantly associated with health status, e.g., clients identified as "at risk" on CHA for heart attack used 2.86 times more services than clients not at risk. Pursuing PGT was not significantly associated with increased use of services post CHA overall or for most of the conditions examined. Our data demonstrate that health status rather than pursuing PGT is the strongest driver of service utilization in this population. Overall, pursuit of PGT and PGT results does not appear to significantly drive the utilization of downstream health services.

Family Experiences with Care for Children with Inherited Metabolic Diseases in Canada: A Cross-Sectional Survey

BACKGROUND AND OBJECTIVE

Children with inherited metabolic diseases often require complex and highly specialized care. Patient and family-centered care can improve health outcomes that are important to families. This study aimed to examine experiences of family caregivers (parents/guardians) of children diagnosed with inherited metabolic diseases with healthcare to inform strategies to improve those experiences.

METHODS

A cross-sectional mailed survey was conducted of family caregivers recruited from an ongoing cohort study. Participants rated their healthcare experiences during their child's visits to five types of healthcare settings common for inherited metabolic diseases: the metabolic clinic, the emergency department, hospital inpatient units, the blood laboratory, and the pharmacy. Participants provided narrative descriptions of any memorable negative or positive experiences.

RESULTS

There were 248 respondents (response rate 49%). Caregivers were generally very or somewhat satisfied with the care provided at each care setting. Appropriate treatment, provider knowledge, provider communication, and care coordination were deemed essential aspects of satisfaction with care by the majority of participants across many settings. Memorable negative experiences were reported by 8-22% of participants, varying by setting. Among participants who reported memorable negative experiences, contributing factors included providers' demeanor, lack of communication, lack of involvement of the family, and disregard of an emergency protocol letter provided by the family.

CONCLUSIONS

While caregivers' satisfaction with care for children with inherited metabolic diseases was high, we identified gaps in family-centered care and factors contributing to negative experiences that are important to consider in the future development of strategies to improve pediatric care for inherited metabolic diseases.

THE ROLE OF WHOLE GENOME SEQUENCING AS A DIAGNOSTIC TOOL FOR CHILDREN WITH MEDICAL COMPLEXITY

BACKGROUND

Genetic testing is often pursued in children with medical complexity (CMC), in an attempt to establish a unifying diagnosis, understand pathogenicity and disease progression, guide care and inform reproductive planning. CMC are defined by at least one chronic condition, technology dependence, multiple subspecialist involvement, and high healthcare utilization. Despite multiple efforts to confirm clinical suspicion of an underlying genetic condition, many remain undiagnosed.

Whole genome sequencing (WGS) is becoming increasingly available as an informative diagnostic tool. The application of genomic technology to this population has the potential to increase the proportion of CMC for whom diagnoses are established, in an effort to reduce time and emotional burden of the diagnostic process, and reduce health care system costs.

OBJECTIVES

The main purpose of this study was to optimize the clinical implementation of state-of-the-art genome diagnostics for CMC, in terms of diagnostic yield.

DESIGN/METHODS

We conducted a prospective study using patients followed by the Complex Care program at a large urban tertiary care center. Research ethics board approval was obtained. Of 435 patients screened, 114 were eligible for inclusion as an underlying genetic condition was clinically suspected but not established to date by conventional genetic testing. To date, 21 participants were evaluated through a clinical genetic assessment, previous genetic testing review and peripheral blood-derived DNA sequence.

A laboratory team identified candidate genetic variants associated with patients’ clinical symptoms, as well as other paediatric medically actionable variants. When found, these variants were validated as clinically significant by comparing the child’s DNA to his parents’. WGS diagnostic yield was then determined by calculating the proportion of cases for which a genetic diagnosis was established.

RESULTS

Of the 21 patients recruited, nine WGS analysis were completed thus far. Among these, four participants were diagnosed with established diseases, two of which were considered as novel diseases. One case was identified with a possible diagnosis, however, the interpretation of this clinical phenotype remains of unknown significance. The other four patients of the study remained undiagnosed.

Given these preliminary results, the diagnostic yield of WGS was predicted at 44% in CMC. This can be compared to a previous study performed at our center in which the diagnostic rate for chromosomal microarray alone was reported to be 8% and microarray plus targeted gene sequencing 13%.

CONCLUSION

This study has shown WGS to be feasible and achieve a higher diagnostic yield in our complex care population. As detection rates improve and laboratory costs decrease overtime, WGS will undoubtedly become a more informative diagnostic tool, particularly in this population. Optimizing the application of this increasingly sophisticated genomic technology warrants further consideration.

Evaluation of the diagnostic accuracy of exome sequencing and its impact on diagnostic thinking for patients with rare disease in a publicly funded health care system: A prospective cohort study

PURPOSE

To evaluate the diagnostic utility of publicly funded clinical exome sequencing (ES) for patients with suspected rare genetic diseases.

METHODS

We prospectively enrolled 297 probands who met eligibility criteria and received ES across 5 sites in Ontario, Canada, and extracted data from medical records and clinician surveys. Using the Fryback and Thornbury Efficacy Framework, we assessed diagnostic accuracy by examining laboratory interpretation of results and assessed diagnostic thinking by examining the clinical interpretation of results and whether clinical-molecular diagnoses would have been achieved via alternative hypothetical molecular tests.

RESULTS

Laboratories reported 105 molecular diagnoses and 165 uncertain results in known and novel genes. Of these, clinicians interpreted 102 of 105 (97%) molecular diagnoses and 6 of 165 (4%) uncertain results as clinical-molecular diagnoses. The 108 clinical-molecular diagnoses were in 104 families (35% diagnostic yield). Each eligibility criteria resulted in diagnostic yields of 30% to 40%, and higher yields were achieved when >2 eligibility criteria were met (up to 45%). Hypothetical tests would have identified 61% of clinical-molecular diagnoses.

CONCLUSION

We demonstrate robustness in eligibility criteria and high clinical validity of laboratory results from ES testing. The importance of ES was highlighted by the potential 40% of patients that would have gone undiagnosed without this test.

Family-centred care interventions for children with chronic conditions: A scoping review

INTRODUCTION

Children with chronic conditions have greater health care needs than the general paediatric population but may not receive care that centres their needs and preferences as identified by their families. Clinicians and researchers are interested in developing interventions to improve family-centred care need information about the characteristics of existing interventions, their development and the domains of family-centred care that they address. We conducted a scoping review that aimed to identify and characterize recent family-centred interventions designed to improve experiences with care for children with chronic conditions.

METHODS

We searched Medline, Embase, PsycInfo and Cochrane databases, and grey literature sources for relevant articles or documents published between 1 January 2019 and 11 August 2020 (databases) or 7-20 October 2020 (grey literature). Primary studies with ≥10 participants, clinical practice guidelines and theoretical articles describing family-centred interventions that aimed to improve experiences with care for children with chronic conditions were eligible. Following citation and full-text screening by two reviewers working independently, we charted data covering study characteristics and interventions from eligible reports and synthesized interventions by domains of family-centred care.

RESULTS

Our search identified 2882 citations, from which 63 articles describing 61 unique interventions met the eligibility criteria and were included in this review. The most common study designs were quasiexperimental studies (n = 18), randomized controlled trials (n = 11) and qualitative and mixed-methods studies (n = 9 each). The most frequently addressed domains of family-centred care were communication and information provision (n = 45), family involvement in care (n = 37) and access to care (n = 30).

CONCLUSION

This review, which identified 61 unique interventions aimed at improving family-centred care for children with chronic conditions across a range of settings, is a concrete resource for researchers, health care providers and administrators interested in improving care for this high-needs population.

PATIENT OR PUBLIC CONTRIBUTION

This study was co-developed with three patient partner co-investigators, all of whom are individuals with lived experiences of rare chronic diseases as parents and/or patients and have prior experience in patient engagement in research (I. J., N. P., M. S.). These patient partner co-investigators contributed to this study at all stages, from conceptualization to dissemination.

Development of a Value Assessment Framework for Pediatric Health Technologies Using Multicriteria Decision Analysis: Expanding the Value Lens for Funding Decision Making

OBJECTIVES

A health technology assessment (HTA) does not systematically account for the circumstances and needs of children and youth. To supplement HTA processes, we aimed to develop a child-tailored value assessment framework using a multicriteria decision analysis approach.

METHODS

We constructed a multicriteria-decision-analysis-based model in multiple phases to create the Comprehensive Assessment of Technologies for Child Health (CATCH) framework. Using a modified Delphi process with stakeholders having broad disciplinary and geographic variation (N = 23), we refined previously generated criteria and developed rank-based weights. We established a criterion-pertinent scoring rubric for assessing incremental benefits of new drugs. Three clinicians independently assessed comprehension by pilotscoring 9 drugs. We then validated CATCH for 2 childhood cancer therapies through structured deliberation with an expert panel (N = 10), obtaining individual scores, consensus scores, and verbal feedback. Analyses included descriptive statistics, thematic analysis, exploratory disagreement indices, and sensitivity analysis.

RESULTS

The modified Delphi process yielded 10 criteria, based on absolute importance/relevance and agreed importance (median disagreement indices = 0.34): Effectiveness, Child-specific Health-related Quality of Life, Disease Severity, Unmet Need, Therapeutic Safety, Equity, Family Impacts, Life-course Development, Rarity, and Fair Share of Life. Pilot scoring resulted in adjusted criteria definitions and more precise score-scaling guidelines. Validation panelists endorsed the framework's key modifiers of value. Modes of their individual prescores aligned closely with deliberative consensus scores.

CONCLUSIONS

We iteratively developed a value assessment framework that captures dimensions of child-specific health and nonhealth gains. CATCH could improve the richness and relevance of HTA decision making for children in Canada and comparable health systems.

Implementation of a Sudden Cardiac Death Risk Prediction Tool in Clinical Practice Through Electronic Health Records (INSERT-HCM Study Design)

Sudden cardiac death is a leading cause of mortality in children with hypertrophic cardiomyopathy (HCM). The PRecIsion Medicine in CardiomYopathy consortium developed a validated tool (PRIMaCY) for sudden cardiac death risk prediction to help with implantable cardioverter defibrillator shared decision-making, as recommended by clinical practice guidelines. The Implementing a Sudden Cardiac Death Risk Assessment Tool in Childhood HCM (INSERT-HCM) study aims to implement PRIMaCY into electronic health records (EHRs) and assess implementation determinants and outcomes. INSERT-HCM is a prospective, multicentre, hybrid type-3 mixed-methods implementation study of an EHR-embedded risk calculator across Canadian pediatric hospitals. The Active Implementation Framework will inform a staged implementation process, with organization-based implementation teams facilitating the implementation technical installation and implementation process. PRIMaCY will be installed as a user-tested EHR-integrated tool and implemented in practice using an organization and provider-focused strategy at participating hospitals. Technical installation and implementation strategies will be optimized for each healthcare setting. The Implementation Outcomes Taxonomy will inform implementation outcomes. Back-end EHR data will assess tool adoption, penetration, and fidelity. The Consolidated Framework for Implementation Research will assess implementation determinants (facilitators and barriers), and sustainability in clinical practice will be explored. INSERT-HCM will inform best practices for implementing an evidence-based digital health solution within hospital EHRs and clinical workflows to improve guideline-directed care. Developing an effective implementation strategy will inform the future dissemination of EHR-integrated digital health tools to the broader scientific and clinical community.
