Cost-Effectiveness Modelling of Sequential Biologic Strategies for the Treatment of Moderate to Severe Rheumatoid Arthritis in Finland

Abstract: Objective: The main objective was to compare the cost-effectiveness of therapeutic options in moderate or severe rheumatoid arthritis (RA) when a clinical response to a first TNF-blocker, either etanercept (ETA), adalimumab (ADA), or infliximab (INF), is insufficient. Methods: Effectiveness criteria were defined as remission (RS), low disease activity (LDAS), and moderate to high disease activity (MHDAS). Cost-effectiveness was derived as cost per day in RS and in LDAS using simulation modelling to assess six sequential biologic strategies over 2 years. Each sequential treatment strategy was composed of three biologic agents and included a first anti-TNF agent, ETA, ADA or INF, followed by either abatacept (ABA) or rituximab (RTX) as a second therapeutic option in case of an insufficient response, followed by another anti-TNF agent in case of further insufficient response. Results: Over two years and taking into account biologic costs, the following estimated mean costs per day in RS and LDAS were respectively of �829 and �428 for the biologic sequence composed of ADA-ABA-ETA, �1292 and �516 for the sequence ADA-RTX-ETA, �829 and �429 for the sequence ETA-ABA-ADA, �1292 and �517 for the sequence ETA-RTX-ADA, �840 and �434 for the sequence INF-ABA-ETA, and �1309 and �523 for the sequence INF-RTX-ETA. Conclusion: The treatment sequences including ABA as the second biologic option appear more cost-effective than those including RTX in a patients with moderate to severe RA and an insufficient response to a first anti-TNF agent.

Men's preferences for prostate cancer screening: A discrete choice experiment

Background: Screening for prostate cancer (PC) may save lives, but overdiagnosis and overtreatment are serious drawbacks. We aimed to determine men's preferences for PC screening, and to elicit the trade-offs they make. Methods: A discrete choice experiment (DCE) was conducted among a population-based random sample of 1000 elderly men (55-75-years-old). Trade-offs were quantified with a panel latent class model between five PC screening aspects: risk reduction of PC-related death, screening interval, risk of unnecessary biopsies, risk of unnecessary treatments, and out-of-pocket costs. Results: The response rate was 46% (459/1000). Men were willing to trade-off 2.0% (CI: 1.6%-2.4%) or 1.8% (CI: 1.3%-2.3%) risk reduction of PC-related death to decrease their risk of unnecessary treatment or biopsy with 10%, respectively. They were willing to pay \[euro]188 per year (CI: \[euro]141-\[euro]258) to reduce their relative risk of PC-related death with 10%. Preference heterogeneity was substantial, with men with higher educational levels having a lower probability to opt for PC screening than men with lower educational levels. Conclusion: Men were willing to trade-off some risk reduction of PC-related death to be relieved of the burden of biopsies or unnecessary treatments. Increasing knowledge on overdiagnosis and overtreatment, especially for men with lower educational levels, is warranted to prevent unrealistic expectations from PC screening. © 2013 Cancer Research UK.

A decision analysis of long‐term lithium treatment and the risk of renal failure

OBJECTIVE: To establish whether lithium or anticonvulsant should be used for maintenance treatment for bipolar affective disorder (BPAD) if the risks of suicide and relapse were traded off against the risk of end-stage renal disease (ESRD). METHOD: Decision analysis based on a systematic literature review with two main decisions: (1) use of lithium or at treatment initiation and (2) the potential discontinuation of lithium in patients with chronic kidney disease (CKD) after 20 years of lithium treatment. The final endpoint was 30 years of treatment with five outcomes to consider: death from suicide, alive with stable or unstable BPAD, alive with or without ESRD. RESULTS: At the start of treatment, the model identified lithium as the treatment of choice. The risks of developing CKD or ESRD were not relevant at the starting point. Twenty years into treatment, lithium still remained treatment of choice. If CKD had occurred at this point, stopping lithium would only be an option if the likelihood of progression to ESRD exceeded 41.3% or if anticonvulsants always outperformed lithium regarding relapse prevention. CONCLUSION: At the current state of knowledge, lithium initiation and continuation even in the presence of long-term adverse renal effects should be recommended in most cases

Screening for cervixcancer kan vara kostnadseffektiv. Kombinationen cellprov och HPV-test skulle ge ytterligare vinster.

En hälsoekonomisk utvärdering av cellprovsscreening för cervixcancer har saknats vad gäller svenska förhållanden. I en modellstudie jämfördes effekter av och kostnader för gynekologisk cellprovskontroll med och utan tillägg av test för humant papillomvirus (HPV). Med cellprovsscreening i åldern 32–60 år vart tredje till vart femte år minskar risken att insjukna i invasiv cervixcancer med 88 procent, och sjukvårdens kostnader halveras jämfört med att inte screena. Med tillägg av ett eller två HPV-test vid 32 års ålder och oförändrad screeningpolicy ökar kostnaderna, och inga hälsovinster kan påvisas. En screeningstrategi med cellprov i kombination med HPV-test vid enbart tre tillfällen i livet – vid 32, 41 och 50 års ålder – kostar mindre och ger, enligt modellen, hälsovinster jämfört med enbart cellprovsscreening i åldern 32–60 år
