Other factors which may contribute to decreased vaccination timeliness in Aboriginal children have been identified in international studies.
Further work is required to investigate the performance of negative binomial cusums more systematically using both large sample and prospective methods, and investigate the integration of this monitoring approach with other methods which may improve the sensitivity and timeliness of alerts and minimise the false alarms generated.
In contrast to curated, more limited, and yet time-delayed SDC data source, the IEN data source provides timeliness and access to a wider variety of data, yet which may be handicapped by curation biases (Still et al. 2014b; Basole et al. 2015).
Timeliness can be related to the time since the first outbreak case or to the cumulative number of outbreak cases which have occurred, which may be more intuitive when describing the timeliness of detection performance for diseases with long latent periods.
We also have detailed data on timeliness of procedures, extent of lymph node procedures, positive node counts, and reconstruction, which may serve as additional surgical quality measures.
Importantly, use of combination vaccines improves vaccination coverage rates and the timeliness of vaccination., DTP has been combined with hepatitis B surface antigen as DTPw-HBV, which may also be mixed with Hib conjugate vaccines (DTPw-HBV/Hib).
The studies reported were all carried out under different health systems which may have been influenced by different payment systems, admission and discharge policies, and timeliness of data [ 40].
Furthermore, our findings suggest that the temporal distribution of cases (i.e., the shape of the epidemic curve) generally does not affect sensitivity but may affect timeliness, which Wang et al. observed in evaluating an autoregressive periodic model (APM [ 10].
