Reporting and methodological quality checklist | The checklist designed for falls prevention economic evaluations by a panel of falls prevention experts [32] was adapted to specifically suit decision models. There were 32 items, each scored 0 (recommendation not followed), 0.5 (partially followed), and 1 (fully followed), giving maximum score of 32. See Table A2 in Supplementary Materials for adapted version. |
(A) Model and evaluation overview | 1. Bibliography: author(s); publication year 2. Setting and aim: country; region; decision-maker; evaluation aim 3. Target population demographics and comorbidities (e.g., residence,a age, sex, socioeconomic status, health conditions unrelated to falls risk) 4. Type of analysis: e.g., CEA; CUA; CBA; ROIb 5. Perspective (e.g., public sector, societal) 6. Cost-effectiveness threshold: monetary amount and type (e.g., health opportunity cost in healthcare system, willingness to pay as consumer) 7. Model type (e.g., decision tree, Markov) 8. Model time horizon 9. Discount rates (if time horizon longer than 1 year) 10. Model cycle length (if any) |
(B) Falls epidemiology features | 1. Characterising baseline falls risk of target population 2. Characterising multiple falls per year (recurrent falls) 3. Risk factors for falls 4. Health consequences of falls: fall/injury type; long-term health consequences (e.g., institutionalisation, excess mortality risk) 5. Health utility data: fall-related loss; comorbidity status 6. Economic consequences of falls: care resource types; unit costs; all-cause/comorbidity care costsc |
(C) Falls prevention intervention features | 1. Intervention characteristics: type;d comparator(s); component; access pathwaye 2. Falls risk screening methodf 3. Intervention resource use and costs: auxiliary implementation resources (e.g., marketing to improve uptake); therapeutic resources (e.g., staff labour). 4. Intervention efficacy: metric;g fall type;h effectiveness periodi 5. Wider health effects of interventions beyond falls preventionj |
(D) Evaluation methods and results | 1. Model validity: structural/face;k internal; external; crossl 2. Assessing parameter uncertainty: DSA; PSA 3. Scenario analyses: to assess impact of structural assumptions on outcomes. 4. Aggregate health and cost outcomes (e.g., total intervention cost, total QALY gain, total number of falls prevented) 5. Cost-per-unit ratios (e.g., incremental cost per QALY gain) 6. Wider decisional outcomes (e.g., reduction in social inequities of health) 7. Currency: original type/year; conversion to same currency for comparison 8. Discussion by evaluation authors: generalisability; policy implementation; model strengths and limitations |
(E) Key methodological challenges for public health economic model | 1. Capturing non-health outcomes and societal intervention costs 2. Considering heterogeneity and dynamic complexity: e.g., long-term progression of falls risk factors/profile 3. Considering theories of human behaviour and implementation: e.g., implementation quality (i.e., uptake and adherence rates) 4. Considering social determinants of health and conducting equity analyses |
