Key Performance Indicators, Centre Reports, and more Stephen McDonald
Background • A number of ongoing work themes exist within ANZDATA for generating output • Stock and flow figures • Annual Report • Contributor requests • Responses to information needed for various projects • Research projects (internal and external analyses) • Outcomes reporting
Outcomes reporting • Recent years have seen a growth of interest in outcomes reporting • Centre reports have been part of ANZDATA for many years, with increasing emphasis in recent years • At “parent hospital level” • Limited distribution historically
4 Adjusted relative risk 2 1 .5 .2 0 20 40 60 80 Units, ranked by RR RR 95% CI Mortality rate during dialysis treatment in Australia 2006-10, adjusted for demographics and comorbidities Dialysis outcome
What is happening to centre reports? • Greater reporting of demographics and comorbidities • Adjusted analyses in transplanting centre and dialysis reports • Details of models supplied • Graphs • Funnel plots • CUSUM plots (transplant)
You need a model • Logistic regression model (transplant), Poisson model (dialysis) • Adjusted for demographics, comorbidities (donor and XM variables) • With this model, derive a probability of “expected” failure for each person / graft based on covariate matrix • Compare this with actual outcomes
Which predictors are important? Predictive power of multivariate Cox model predicting graft survival, all DD transplants 2001-2009, with sequential addition of covariate groups
Factors within the control of centre These may be why a particular centre gets good or bad results Factors that occur as a result of treatment decisions For example, don’t adjust for Choice of dialysis modality, HD access Use of immunosuppressives, rejection, 1 month graft function… Don’t adjust for…
Other graphical demonstrations of output • Funnel plots are a static measure and summarise performance (relative to a comparator) over a fixed period of time. • Lack a dynamic element • Weight recent and distant results equally

Why KPIs? • Mortality is an insensitive and late indicators of problems • Hopefully rare • Outcome of complex series of events • Incompletely ascertained • Important to monitor as best we can • Key Process indicators • Simpler to understand, easier to address • Need to be valid and correctable (and related to meaningful outcomes)
KPI Project • Dialysis KPI project commenced 2011 • At instigation of DNT committee • 2 markers chosen – Peritonitis and HD access at first treatment • Deliberately limited to existing data collection • NO additional data collected • Based on real time ANZDATA data collection
KPI reporting -- access • Quarterly identified feedback to units
Where to from here? • COMMUNICATE • Improve data collection • Improve access to results • Enhance reporting • Add peritonitis rates • Access subdivided by late referral • Graphs etc etc • Or is it all just too hard?
