Cost-effectiveness of Intermittent vs Continuous Pulse Oximetry Monitoring in Infants Hospitalized With Stabilized Bronchiolitis.

Importance: Pulse oximetry is a noninvasive technology that is integral to the supportive care of hospitalized infants with bronchiolitis. A multicenter, randomized trial comparing the effectiveness of intermittent vs continuous pulse oximetry found similar length of hospital stay and safety outcomes, and greater nursing satisfaction, with intermittent monitoring. Objectives: To evaluate the cost-effectiveness of intermittent vs continuous pulse oximetry in hospitalized infants with stabilized bronchiolitis. Design, Setting, and Participants: An economic evaluation concurrent with a randomized trial in community and tertiary children's hospitals in Ontario, Canada, was conducted using a probabilistic analysis. Patients were enrolled from November 1, 2016, to May 31, 2019. Data included infants aged 4 weeks to 24 months hospitalized with bronchiolitis, with or without supplemental oxygen, after stabilization. The cost-effectiveness analysis adopted a societal and health care system perspective and a time horizon from hospitalization to 15 days post-discharge. Patient level direct health care costs and indirect costs were included. Health resource use, costs, and clinical outcomes were obtained from trial data. Publicly available pricing resources were used to supplement costs. Ranges for sensitivity analysis were based on 95% confidence intervals of the trial data. All costs were reported in 2021 Canadian dollars. Interventions: Intermittent (every 4 hours) vs continuous pulse oximetry using an oxygen saturation target of 90% or higher. Main Outcomes and Measures: Costs and incremental costs. Results: Trial data from 229 infants (median [IQR] age, 4.0 [2.2-8.5] months; 136 boys [59.4%], 93 girls [40.6%]) were included. Mean societal costs per patient were $6879 (95% CI, $3393 to $12 317) in the intermittent and $7428 (95% CI, $1743 to $25 011) in the continuous group with a mean incremental cost of -$548 (95% CI, -$18 486 to $8105). Mean health care system costs per patient were $4195 (95% CI, $1191 to $9461) in the intermittent and $4716 (95% CI, $335 to $22 093) in the continuous group (incremental cost, -$520; 95% CI, -$18 286 to $7358). The mean effect measure of length of stay was similar between the 2 groups: 37.4 hours (95% CI, 1.0 to 137.7 hours) in the intermittent group and 38.5 hours (95% CI, 0 to 237.1 hours) in the continuous group. One-way sensitivity analyses on all variables revealed that the findings were robust and the incremental costs were not sensitive to the uncertainty within the defined ranges. Conclusions and Relevance: In this prospective economic evaluation study, we found that costs were similar for intermittent and continuous pulse oximetry considering societal and health care perspectives. Given that clinical outcomes between monitoring strategies are comparable and that other practice considerations favor intermittent monitoring, these findings provide additional information that support the use of intermittent monitoring in hospitalized infants with stabilized bronchiolitis.

Trio genome sequencing for developmental delay and pediatric heart conditions: A comparative microcost analysis.

PURPOSE: Genome sequencing (GS) can aid clinical management of multiple pediatric conditions. Insurers require accurate cost information to inform funding and implementation decisions. The objective was to compare the laboratory workflows and microcosts of trio GS testing in children with developmental delay (DD) and in children with cardiac conditions. METHODS: Cost items related to each step in trio GS (child and 2 parents) for both populations were identified and measured. Program costs over 5 years were estimated. Probabilistic and deterministic analyses were conducted. RESULTS: The mean cost per trio GS was CAD$6634.11 (95% CI = 6352.29-6913.40) for DD and CAD$8053.10 (95% CI = 7699.30-8558.10) for cardiac conditions. The 5-year program cost was CAD$28.11 million (95% CI = 26.91-29.29) for DD and CAD$5.63 million (95% CI = 5.38-5.98) for cardiac conditions. Supplies constituted the largest cost component for both populations. The higher cost per sample for the population with cardiac conditions was due to the inclusion of pharmacogenomics, higher bioinformatics labor costs, and a more labor intensive case review. CONCLUSION: This analysis indicated important variation in trio GS workflow and costs between pediatric populations in a single institution. Enhanced understanding of the clinical utility and costs of GS can inform harmonization and implementation decision-making.

Determining accurate costs for genomic sequencing technologies-a necessary prerequisite.

Genome sequencing (GS) is increasingly being translated into clinical practice and is a technology characterized by a complex multi-step workflow. Funding decisions for GS would be aided by formal economic evaluation of GS platforms, but these analyses require detailed costing. This article addresses the importance of and challenges associated with costing GS using a GS microcosting project in autism spectrum disorder as an illustrative example.

What Influences the Cost Effectiveness of Dabigatran versus Warfarin for Stroke Prevention in Atrial Fibrillation: A Systematic Review.

OBJECTIVES: The introduction of new oral anticoagulants for the prevention of stroke in atrial fibrillation (AF) has changed the clinical management of AF. To inform decision making around dabigatran by identifying factors influencing cost-effectiveness results, we undertook a systematic review of economic evaluations of dabigatran versus warfarin for the prevention of stroke in AF patients. METHODS: A systematic literature search of Ovid Medline and Embase, Wiley's Cochrane Library, HEED, PubMed databases and grey literature was carried out for primary economic evaluations comparing dabigatran versus warfarin in patients with AF. Data on study characteristics, model inputs and results, and sensitivity analyses were abstracted and synthesized qualitatively. RESULTS: Twenty-three economic evaluations were identified and RE-LY was cited in 52% of studies as the source of the efficacy data. Twenty evaluations used Markov modelling, 2 performed discrete event simulation, and 1 was a trial-based evaluation. Eighty-two percent reported base case incremental cost-effectiveness ratios (ICERs) of less than $50,000 USD/QALY. Key variables, including international normalized ratio (INR) control, the cost of monitoring, risk of stroke and bleeding, and age were found to alter the conclusions in only a few studies. Less commonly explored factors included time horizon and cost of long-term care follow-up. CONCLUSIONS: Several factors should be considered when interpreting the results of economic analyses which are based on randomized clinical trial evidence. Real-world data are needed to further assess the clinical and economic consequences of dabigatran relative to warfarin for the prevention of stroke in AF.

Management of Hospital Formularies in Ontario: Challenges within a Local Health Integration Network.

BACKGROUND: Expenditures on drugs dispensed and administered to patients in Canadian hospitals have been estimated at $2.4 billion per year. Pharmacy and therapeutics (P&T) committees play a key role in the evaluation and management of drug therapies in this setting. Hospitals differ with respect to the composition of these committees, their members' expertise, and the processes used for making formulary decisions. OBJECTIVES: To examine the current processes for formulary drug review from the perspective of P&T committees and their individual members, and to examine the needs and preferences of these stakeholders related to evidence review and potential collaborative drug review processes within a large Local Health Integration Network (LHIN) in Ontario. METHODS: Twenty-three sites within 10 hospital corporations in LHIN 4 (Hamilton Niagara Haldimand Brant) were recruited. A 2-part questionnaire was developed and pretested for clarity and comprehensiveness. The institution profile section of the questionnaire was to be completed by pharmacy directors and the P&T section by committee members. RESULTS: Ten pharmacy directors and 28 committee members representing 10 P&T committees responded. A mean of 6.4 new drug requests were reviewed annually by each P&T committee. Across the LHIN, the workload associated with reviewing submissions for new drugs to be added to the formulary represented 0.84 full-time equivalent. The quality of clinical evidence in the drug submissions was rated more favourably than the quality of economic evidence; furthermore, the use of economic evidence was limited by a lack of health economics expertise within the committees. A centralized review process for the LHIN was perceived as beneficial to improve efficiency, the quality of review, and standardization, and also to reduce costs. CONCLUSIONS: Across the Hamilton Niagara Haldimand Brant LHIN, considerable time and resources are spent on the review of potential new drugs for addition to the hospitals' formularies. A standardized formulary review process, with greater use of provincial and national drug reviews, would likely benefit all LHINs.

CONTEXTE: Les dépenses pour les médicaments distribués et administrés aux patients dans les hôpitaux canadiens ont été évaluées à 2,4 milliards de dollars par année. Les comités de pharmacologie et de thérapeutique jouent un rôle central dans l'analyse et la prise en charge des pharmacothérapies dans ce milieu. La composition de ces comités et l'expertise de leurs membres varient d'un hôpital à l'autre, tout comme les processus qui y sont employés pour prendre des décisions à propos de la liste des médicaments. OBJECTIFS: Étudier les processus actuels d'ajout de médicaments à la liste locale du point de vue des comités de pharmacologie et de thérapeutique et de leurs membres. Examiner les besoins et préférences de ces parties prenantes quant à l'analyse des données probantes et aux potentiels processus collaboratifs d'évaluation des médicaments au sein d'un important réseau local d'intégration des services de santé (RLISS) ontarien. MÉTHODES: Vingt-trois établissements dans 10 organisations hospitalières du RLISS 4 (Hamilton Niagara Haldimand Brant) ont été retenus. On a élaboré un questionnaire de deux parties qui a été testé au préalable pour en vérifier la clarté et l'exhaustivité. La section sur le profil de l'établissement devait être remplie par les directeurs de pharmacie et celle sur la pharmacologie et la thérapeutique devait l'être par les membres des comités. RÉSULTATS: Dix directeurs de pharmacie et 28 membres représentant 10 comités de pharmacologie et de thérapeutique ont répondu. En moyenne, 6,4 nouvelles demandes d'ajout de médicament étaient analysées annuellement par chaque comité. Dans l'ensemble du RLISS, la charge de travail nécessaire à l'analyse des demandes d'ajout de nouveaux médicaments à la liste locale représentait 0,84 d'un poste équivalent temps plein. La qualité des données cliniques probantes dans les demandes d'ajout était considérée plus favorablement que celle des données économiques. De plus, comme les membres des comités ne possédaient pas l'expertise nécessaire en économie de la santé, l'utilisation des données probantes à ce sujet était limitée. Un processus centralisé d'analyse pour le RLISS était perçu comme avantageux pour améliorer l'efficience, la qualité de l'analyse et la normalisation ainsi que pour réduire les coûts. CONCLUSIONS: Dans l'ensemble du RLISS de Hamilton Niagara Haldimand Brant, beaucoup de ressources et de temps sont accordés à évaluer l'ajout de médicaments à la liste locale. Tous les RLISS tireraient sûrement profit d'un processus normalisé d'ajout à la liste locale des médicaments ainsi que d'une meilleure utilisation des évaluations réalisées par les organismes provinciaux et national.

Do different decision-analytic modeling approaches produce different results? A systematic review of cross-validation studies.

When choosing a modeling approach for health economic evaluation, certain criteria are often considered (e.g., population resolution, interactivity, time advancement mechanism, resource constraints). However, whether these criteria and their associated modeling approach impacts results remain poorly understood. A systematic review was conducted to identify cross-validation studies (i.e., modeling a problem using different approaches with the same body of evidence) to offer insight on this topic. With respect to population resolution, reviewed studies suggested that both aggregate- and individual-level models will generate comparable results, although a practical trade-off exists between validity and feasibility. In terms of interactivity, infectious-disease models consistently showed that, depending on the assumptions regarding probability of disease exposure, dynamic and static models may produce dissimilar results with opposing policy recommendations. Empirical evidence on the remaining criteria is limited. Greater discussion will therefore be necessary to promote a deeper understanding of the benefits and limits to each modeling approach.

Economic burden of illness associated with diabetic foot ulcers in Canada.

BACKGROUND: The primary objective was to estimate the national burden of illness in Canada for diabetic foot ulcer (DFU) for 2011. Secondary objectives included estimating the national incidence and prevalence of DFU, and the 3-year average cost for DFU incident cases. METHODS: Analyses were conducted using four national databases for the period April 1, 2006 to March 31, 2011, with cases being identified by ICD-10 CA codes. Resource utilization and costs, expressed in 2011 Canadian dollars, were estimated for DFU-related hospitalizations, emergency care (ER), same day surgeries, home care, long term care, physician visits and caregiver time losses. RESULTS: In Canada in the year 2011, DFU was associated with 16,883 hospital admissions (327,140 days), 31,095 ER or clinic visits, 41,367 rehabilitation clinic visits, and 26,493 interventions, including 6,036 amputations and 5,796 surgical debridements. This acute institution care represented $320.5 M, and with an additional $125.4 M for home care and $63.1 M for long term care, the annual cost associated with DFU-related care was $547.0 M, or $21,371 annual cost per prevalent case. In 2011, the national prevalence of DFU was 25,597 cases (75.1 per 100,000 population), consisting of 16,161 men (63.1%) and 9,436 women (36.9%), and an estimated 14,449 incident cases. For an incident case of DFU, the average 3-year cumulative cost was $52,360. CONCLUSION: The annual burden for DFU cases that have at least one admission or ER/clinic visit over a 5 year period is higher than previously reported.
