Eligible patients were followed from July 1997
when home nursing data first
became available, to death or census in November 2007. Home nursing data from the
major community nursing service provider were linked with data from the Fremantle
Diabetes Study. Cox and zero-inflated negative binomial (ZINB) regression modelling was
used to identify predictors of incident home visits and visit frequency, respectively. Direct
costs were estimated from the service provider’s unit costs.
