APPENDIX 5: FIGURES FOR CLINICAL REVIEW
Figure 1: Funnel plot of all-cause mortality: High vs intermediate/low target Hb protocols
This funnel plot is a simple scatter plot of each trial’s precision (inversion of standard error) on the y-axis against each trial’s log RR on the x-axis. Since small trials have less precision and large trials have more, the scatter should form an inverted funnel when there are no systematic missing trials. Markers are sized according to the trial’s sample size; larger trials are marked with larger circles. A vertical line is drawn through our overall log RR (0.126, that is, a RR risk of 1.13) to aid the eye in detecting symmetry (an inverted funnel) or asymmetry. Our funnel plot appears mildly asymmetric. Therefore, there are possibly missing studies favouring a intermediate/low target Hb protocol. RR=relative risk

Costs Direct medical: EPO costs, hospitalizations, outpatient visits, treatment while on dialysis (e.g., transfusion) Productivity costs for patient and family: employment, benefits, home productivity, leisure
Cost-modelling using data from published literature, retrospective cost analysis, healthcare funding organizations, and a small unpublished internal QOL study in Italy and Spain Cost categories include: EPO acquisition, transfusions, and treatment of adverse effects (to both EPO and transfusions)
EPO costs EPO costs (administration, dispensing, preparation), syringes, additional blood tests, blood pressure monitoring
EPO costs, iron costs, administration, complications, hospitalization, blood transfusion. Informed by expert opinion (n=5) where study data lacking
EPO costs Annual costs of dialysis, transplantation, hospitalization, physical claims, and iron sucrose
Model details No model Model used to estimate costs No formal model (simple tree assumed)
Decision tree Re-analysis using model from Leese78
Markov model Health states of “hemodialysis”, “renal transplant” and “dead”
Sensitivity analysis approach
None performed Country specific sensitivity analysis based on local usage, costs, and adverse effects Tested assumption of increased survival by 10%
Fraction of persons who are on IV switching to SC (range 25-100%) EPO reduction varied between 95% CI from RCT (32%, 95% CI 14-50) Dose reduction from observational data (range 10-50%)
95% CI of response probabilities reported in study Time horizon increased from 20wk to 1y Drug and administration costs
Identified plausible range, specific emphasis on model inputs that have changed over time from the original analysis by Leese et al.78
Focus on EPO dose required to achieve target Hb and QOL achieved for each target

Important parameters from sensitivity analysis
Not applicable Cost per QALY range by country France $83,964–168,797 Germany $64,171–153,298 Italy $115,774–595,967 Spain $266,023–349,215 UK $112,880–176,077
Range of cost savings: $15M/y for a 10% reduction in dose, with 25% switching from IV to SC $295M/y for a 50% reduction in dose, with 100% switching from IV to SC
Higher doses become more attractive as the cost per administration of epoetin increases
Compared with the orginal study by Leese,78 the ICUR has dropped primarily due to: Decreased EPO dose (~55% drop in ICUR) Decrease in cost per unit
Substantial increases in QOL Reduction in hospitalization Lower dose of agent to achieve target Hb

Base case results Net cost savings of $1,166.25/y per patient
Cost per QALY range $58,600-349,000 (depending on country and assumptions) Weighted average $137,000
Direct cost savings of $47M/y for a 33% reduction in dose, with 25% switching from IV to SC
At 20 wk: $1,090-1,236 for 6,000 U $1,460-1,601 for 9,000 U $1,553-1,668 for 12,000 U (administration costs $1-10)
Incremental cost per QALY gained £17,067
Incremental cost per QALY gained $55,295 for 110-120 vs 95-105 g/L $613,015 for 120-125 vs 110-120 g/L $828,215 for 140 vs 120-125 g/L
Conclusions “…improvements in quality of life and activity can be achieved in hemodialysis patients treated with relatively low doses of EPO..., and resulting benefits more than cover the cost of this therapy.”
“…EPO offers the possibility of measurable gains in quality of life for patients, but… the costs of the treatment are considerably greater than any likely resources savings…”
“Administering EPO subcutaneously would provide substantial cost savings to Medicare.”
“[EPO dose of 6,000 U] is the least costly of the 3 regimens studied in CAPD patients…” “The most cost-effective strategy was to use the lowest effective dose, reserving the highest dosage for patients who do not response after 2 months.”
“After 10 years of further experience with the use of EPO the cost-effectiveness ratio now falls within the range considered acceptable by NICE in the UK”
“Aiming for Hb targets in excess of 120 g/L is associated with unfavorable cost-effectiveness ratios and should not be undertaken based on current data.”

respectively) - Fraction eligible patients already treated defined by number of persons on ESA divided by those with hemoglobin below
threshold and those on ESA ESA=erythropoietic stimulating agents
