Bacteræmi: En ny kvalitetsindikator?
Udtræk fra MiBi 3287 tilfælde hos 2127 patienter Alle patienter i DNSL 2677 incidente patienter 4937 prævalente patienter I alt 7614 patienter
2
Microbiology: First Bacteraemia
Staphylococcus 46%
3
Microbiology: First and Fourth Bacteraemia
4
Time to first Bacteraemia
Excess risk Excess Risk HD 12% RT 10% PD 0% Annual Risk HD 14% PD 9% RT 2% 6-month Incidence HD 18% PD 4% RT 14% Annual risk P<0.001
5
Planned vs. Unplanned HD
Excess Risk AV Fistula % Permanent Tunneled 5% Temporary Tunneled % Temporary % Annual Risk AV Fistula % Permanent Tunneled % Temporary Tunneled 14% Temporary % P<0.001
6
Correlations to excess risk and annual rate of bacteraemia (1)
Age DM % All patients Sex: No effect
7
Correlations to excess risk and annual rate of bacteraemia (2)
Charlson Comorbidity Index Gram Stain % All patients
8
Patient survival after first bacteraemia
Excess Risk HD % PD % Annual Risk HD % PD % P<0.01
9
Correlations to mortality after first bacteraemia (1)
Access (HD patients only) Age (All patients) % Bacteraemia less than 6 months after ESRD Number needed to kill (NNK) Temporary 33 Temporary tunneled 70
10
Correlations to mortality after first bacteraemia (2)
Charlson Comorbidity Index Gram stain, DM & Sex: No effect % All patients
11
Quality Indicators by Center 2010-14
12
Konklusioner Mulige indikatorer
Incidens af første bacteræmi episode efter 6 måneder Incidens af alle episoder pr. patient/år delt efter behandlingsmodalitet (HD,PD,RT) Mortalitet efter 1. episode (alle dialysepatienter) Behov for komorbiditetsjustering (alder, CCI, DM)?
13
Microbiology: First and Second Bacteraemia
14
Microbiology: Third and Fourth Bacteraemia
15
HD Access and Gram Type Excess risk Annual rate HD only
16
6-month mortality after first bacteraemia by center
All patients. Range 21-42% % Excess Risk 20% Annual Rate 22% 6-month mortality 33%
17
6 month bacteraemia incidence by Center
HD only, first bacteraemia episode only Range 11-25% % Center
18
Bacteraemia incidence 2010-2014 by center
HD only, all episodes Range 14-32% Denmark HD %/yr PD %/yr RT %/yr % Center
19
Planned vs. Unplanned PD
No excess risk Planned %/yr Unplanned 13%/yr P<0.01
20
Calculation of Excess risk and Annual Risk
A= Event-free survival at 0.5 years B= Event-free survival at 2.5 years Annual rate (%) = (1-(B/A)) x 100 Excess risk (%) = (1 - (B/A)0.25) x 100
