The Swiss Transplant Cohort Study – PD Dr Michael T Koller National Epidemiologist & Head of the data center of the STCS On behalf of all members of the STCS
2 We write the medical history that others read. 4) 4) Not long ago, the University Hospital of Zurich transplanted to two patients simultanously a double lung by segmentation of the donor lung. The girl and the jung men, who suffered from birth of CF got a new life – and medicine a new chapter of history.
An example of STCS collaboration the ad to … What was exactly done in Zürich? How was the outcome in the recipients? Response time from Zürich: 45’ !! 3
USZ: segmentation of the donor lung … Donor: 33y old male † ICH R1: 19 y young male ( ). Double lung. R2: 14 y young female ( ). Double lung
Recipient & : The STCS psychosocial questionaire: «Patient, how is your life?» The 14 years old femaleVisitThe 19 years old man No PSQ: child.BL FUP 6 FUP 12 FUP 24 FUP 36 PSQ 0: not available PSQ 1: student, never misses a dose of IS; sleep quality of 10/10!; No smoking; No problems to perform usual activities; No pain or discomfort. Most of the time cheerful; Single; PSQ 2: no change PSQ 3 (V2): phys activity 2/week 60 min, easy; QoL: 86/100 VAS. Team trust: 10/10. Full adherent to medication. PSQ 4(V2): phys activity 3/week 45 min, very hard!! QoL: 91/100 VAS; Team trust: 10/10. No smoking. Full adherent to drugs. Still single.
«The destiny of individual patients» 7
«The destiny of all solid organ recipients in Switzerland» 8
Example 1 Lung transplantation (LTX) surivival 9
STCS post-LTX overall patient survival 10 Freeman Hospital, Newcastle, adult CF only, US: Columbia University Medical Center (CUMC), , n=274 UNOS Data from 15`642 adult lung TPX recipients between 1987 and 2009 and in US 61 centers ISHLT Registry (worlwide, US, Europe) , n=17’715 40% 12% 25%
Post-LTX overall patient survival: STCS vs ISHLT 11
Lessons from international benchmarking Compared to the others: we perform well! But: 40% of all LTX recipients are dead by 5 years 12
Example 2 Heart transplantation (HTX) survival 13
Post-HTX overall patient survival CTS Registry (Europe) , n=28’828 Only first TPX ISHLT Registry (worlwide, US, Europe) , n=103’299 UNOS Data, 8029 HTX recipients between 2001 and 2009 and in US 61 centers 25% 22% 18%
Post-HTX center-specific survival: The early STCS experience: –
Post-HTX Center-specific survival: The updated STCS experience: –
Lessons from national HTX benchmarking Center-specific differences in post-HTX survival disappeared with time… 1.The increase of the sample size (n=85 n=169) reduced differences due to random variation 2.The discussion of center-specific data lead to critical review of case fatalities with impact on patient care 17
Example 3 Renal transplantation (RTX) by type of donor 18

Example 4 Is there anything similar between lung and liver transplantation? 24
Failure-free survival in liver vs lung tpx recipients 25 Exactly the same first-year survival !
Example 5 Is there anything similar between … heart and kidney-pancreas transplantation? 26
