Introduction: Probabilistic analysis, also referred to as probabilistic sensitivity analysis (PSA), is used extensively in cost-effectiveness evaluations of health technologies. We present methodological guidance for implementing probabilistic analysis and interpreting its results for policy and decision-making.

Methods: We review the methodological issues related to common practices in probabilistic analysis, explore aspects that are currently not widely addressed in the health economics literature, and provide an overview of recent methodological developments.

Background: Maternal-perinatal interventions delivered during pregnancy or childbirth have unique characteristics that impact the health-related quality of life (HRQoL) of the mother, fetus, and newborn child. However, maternal-perinatal cost-utility analyses (CUAs) often only consider either maternal or child health outcomes. Challenges include, but are not limited to, measuring fetal, newborn, and infant health outcomes, and assessing their impact on maternal HRQoL.

Despite the emerging evidence in recent years, successful implementation of clinical genomic sequencing (CGS) remains limited and is challenged by a range of barriers. These include a lack of standardized practices, limited economic assessments for specific indications, limited meaningful patient engagement in health policy decision-making, and the associated costs and resource demand for implementation. Although CGS is gradually becoming more available and accessible worldwide, large variations and disparities remain, and reflections on the lessons learned for successful implementation are sparse.

Background: Omission of family and caregiver health spillovers from the economic evaluation of healthcare interventions remains common practice. When reported, a high degree of methodological inconsistency in incorporating spillovers has been observed.

Aim: To promote emerging good practice, this paper from the Spillovers in Health Economic Evaluation and Research (SHEER) task force aims to provide guidance on the incorporation of family and caregiver health spillovers in cost-effectiveness and cost-utility analysis.

Background: A child's health condition affects family members' health and well-being. However, pediatric cost-utility analysis (CUA) commonly ignores these family spillover effects leading to an incomplete understanding of the cost and benefits of a child's health intervention. Methodological challenges exist in assessing, valuing, and incorporating family spillover effects.

Background & Aims: A growing proportion of children with short bowel syndrome (SBS) remain dependent on long-term parenteral nutrition (PN). Teduglutide offers the potential for more children to decrease PN support and achieve enteral autonomy (EA), but at a significant expense. This study aims to assess the incremental costs of teduglutide plus standard of care compared to standard of care alone in weaning PN support per quality-adjusted life year (QALY) gained in children with SBS.

Economic evaluation is used to determine the optimal provision of services and programs under budget constraints and to inform public and private payer funding decisions. To maximize value-for-money in the design and delivery of programs and services for persons with autism spectrum disorder (ASD), it's essential to generate high-quality economic evidence to inform budget allocation. There is a paucity however, of economic evaluations of interventions for ASD.

Purpose: Advanced genomic and genetic testing technologies are quickly diffusing into clinical practice, but standardized approaches to assessing their clinical utility are limited. Previous work developed and generated preliminary evidence of validity for a novel outcome measure, the Clinician-reported Genetic testing Utility InDEx (C-GUIDE). C-GUIDE is a 17-item measure that captures the utility of genetic testing from the providers' perspective.

Purpose: Although costly, genome-wide sequencing (GWS) detects an extensive range of variants, enhancing our ability to diagnose and assess risk for an increasing number of diseases. In addition to detecting variants related to the indication for testing, GWS can detect secondary variants in BRCA1, BRCA2, and other genes for which early intervention may improve health. As the list of secondary findings grows, there is increased demand for surveillance and management by multiple specialists, adding pressure to constrained health care budgets.

Objectives: The correlations between economic modeling input parameters directly impact the variance and may impact the expected values of model outputs. However, correlation coefficients are not often reported in the literature. We aim to understand the correlations between model inputs for probabilistic analysis from summary statistics.

Precision health aims to personalize treatment and prevention strategies based on individual genetic differences. While it has significantly improved healthcare for specific patient groups, broader translation faces challenges with evidence development, evidence appraisal, and implementation. These challenges are compounded in child health as existing methods fail to incorporate the physiology and socio-biology unique to childhood.

Objective: Generic preference-based HRQOL assessments used expressly for economic evaluation have not been examined in pediatric Crohn's disease (CD) and ulcerative colitis (UC). The objective was to further assess the construct validity of preference-based HRQOL measures in pediatric IBD by comparing the Child Health Utility 9 Dimensions (CHU9D) and Health Utilities Index (HUI) to the disease-specific IMPACT-III and to the generic PedsQL in children with CD and with UC.

Methods: The CHU9D, HUI, IMPACT-III and/or PedsQL were administered to Canadian children aged 6 to 18 years with CD and UC.

Purpose: Health utilities are challenging to ascertain in children and have not been studied in pediatric Crohn's disease (CD) and ulcerative colitis (UC). The objective was to assess discriminative validity by comparing utilities elicited using the Child Health Utility-9 Dimension (CHU9D) to the Health Utilities Index (HUI) across multiple disease activity scales in pediatric UC and CD.

Methods: Preference-based instruments were administered to 188 children with CD and 83 children with UC aged 6 to 18 years.

What people do or engage in in their daily lives, or daily life participation, is often linked to their state of being happy and healthy, as well as potential for living independently. To date, little research has been conducted on daily activity participation by autistic youth at home, at school or in the community. Learning more about individual differences in participation levels and what might influence them can help to create custom supports for autistic youth and their families.

Importance: Screening for amblyopia in primary care visits is recommended for young children, yet screening rates are poor. Although the prevalence of amblyopia is low (3%-5%) among young children, universal screening in schools and mandatory optometric examinations may improve vision care, but the cost-effectiveness of these vision testing strategies compared with the standard in primary care is unknown.

Objective: To evaluate the relative cost-effectiveness of universal school screening and mandated optometric examinations compared with standard care vision screening in primary care visits in Toronto, Canada, with the aim of detecting and facilitating treatment of amblyopia and amblyopia risk factors from the Ontario government's perspective.

Article Synopsis
  • Clear and complete information on study outcomes in clinical trial protocols is essential for regulatory approvals, standardized practices, and transparency in research, but current guidance on these requirements is inconsistent.
  • To address these gaps, there's a need for harmonized standards that integrate with existing frameworks like the SPIRIT 2013 statement.
  • The SPIRIT-Outcomes 2022 extension was developed through expert consultations, a comprehensive review of existing guidelines, and a structured voting process among international panelists to establish essential reporting items for trial outcomes.*
