(A) Setting, population and evaluation framework | 1. Bibliography: author(s); publication year 2. Setting and aim: country; region; decision-maker; evaluation aim 3. Study design: e.g., decision model 4. Target population/sample demographics and comorbidities: e.g., residence – community-dwelling and/or institutionalised; age; sex; SES; health conditions unrelated to falls risk 5. Type of analysis: e.g., CUA, CEA, CBA, ROI 6. Perspective: e.g., public sector, societal 7. Cost-effectiveness threshold clearly stated 8. Time horizon of analysis/model 9. Discount rates (if time horizon is longer than 1 year) |
(B) Falls epidemiology | 1. Target population/sample falls risk factors/profile at baseline 2. Fall type: definition; recording method 3. Health consequences of falls: injury type; long-term consequences (e.g., institutionalisation, excess mortality risk) 4. Health utility measurement: acute vs. long-term impact of falls on health utility; comorbidity-related impact on health utility 5. Economic consequences of falls: care resource types; unit costs; all-cause and fall-related costsa 6. Wider/societal consequences of falls: e.g., social isolation from fear of falling; informal caregiver burden; productivity loss of older persons and caregivers |
(C) Falls prevention intervention | 1. Intervention characteristics: type (e.g., exercise, multifactorial); reach;b primary vs. secondary prevention; main components; staff type; duration, frequency and dose; mutual exclusivity;c comparator(s) 2. Intervention pathway: type (e.g., reactive, proactive, self-referredd); recruitment method; falls risk identification method; mutual exclusivity 3. Intervention resource use: e.g., staff labour and training; transport; overheads 4. Intervention costs: variable vs. fixed costs; economies of scale; societal costs (e.g., time opportunity cost, private co-payment) 5. Intervention implementation: uptake rate; adherence rate; sustainability rate 6. Intervention efficacy: risk of bias in estimation; match with incidence metric;e efficacy fall type;f efficacy durability;g wider health benefits; side effects 7. Intervention study characteristics: study design (e.g., RCT, meta-analysis); population/sample characteristicsh |
(D) Decision model features | 1. Model type and justification of type 2. Model cycle length and justification of length 3. Methods for adopting a long-term model horizoni 4. Methods for characterising baseline demographics and falls risk of model target population 5. Methods for characterising multiple falls in a year (recurrent falls) 6. Methods for characterising dynamic progression of falls risk factors, long-term consequences of falls and falls prevention intervention needj 7. Methods for characterising dynamic progression in comorbidities and changes in care costs, mortality risks, institutionalisation risks and health utilities 8. Methods for incorporating psychological and sociological variables (e.g., motives for healthy behaviour, community institutions) as determinants of falls risk, falls prevention access and model outcomes 9. Methods for incorporating budget and capacity constraints 10. Methods for reducing structural uncertainty of model prospectivelyk 11. Model validation methods/results: face; internal; external |
(E) Evaluation methods and results | 1. Cost-per-unit ratios (e.g., incremental cost per QALY gain) 2. Aggregate health and cost outcomes (e.g., total intervention cost, total QALY gain, total number of falls prevented) 3. Currency: original type/year; conversion to same currency for comparison 4. Handling heterogeneity: subgroup analyses; targeting analyses (under budget or capacity constraint) 5. Handling parameter uncertainty: deterministic sensitivity analysis; probabilistic sensitivity analysis 6. Scenario analyses: testing structural assumptions; scenario suggestions by stakeholders/decision-maker; value of implementation analysis [26] 7. Equity analyses: intervention impact on social inequities in health; estimating efficiency cost or joint equity-efficiency impact of prioritising vulnerable groups (e.g., via distributional cost-effectiveness analysis (DCEA) [27]) 8. Model cross-validity: comparison of results to previous models |
(F) Discussions by evaluation authors | 1. Discussion on issues of generalisability and policy implementation 2. Discussion on strengths and limitations of evaluation |
