Data source: NMDS public hospital data maintained by NZHIS (NZ Health Information Service). The data was extracted from the NMDS on 30 November 1997.
Data are filtered to exclude certain cases (e.g. well babies, transfers). See Appendix 2 for the full list of cases.
Time period covered - 12 months ending 30 June 1997.
ALOS = Average length of stay.
A small number of cases were not submitted to the NMDS (less than 0.1% of all discharges). These cases have not been included in calculations for both ALOS
and percent day case due to the lack of patient record information.
* A shaded ratio implies that the CHE ALOS is significantly different from the national ALOS, after case-mix adjustment.
** A shaded ratio implies that the CHE percentage is significantly different from the national percentage, after case-mix adjustment.
"_" indicates no cases in 1994/95 and/or 1995/96 and/or 1996/97.
"#" indicates a percentage change of 1,000 percent or more.

Data are filtered to exclude certain cases (e.g. well babies, transfers). See Appendix 2 for the full list of cases.
Time period covered - 12 months ending 30 June 1997.
SDR = Standardised discharge ratio.
ALOS = Average length of stay.
RHA totals and SDRs include services provided to publicly funded patients by private providers that were not submitted to the NMDS (less than 0.1% of all discharges),
and 'BD' cases (those which could not be assigned to a sub-region). These cases have not been included in calculations for both ALOS and percent day case
due to lack of patient record information.
* A shaded number implies that the RHA region/sub-regional rate is significantly different from the national rate.
** A shaded number implies that the RHA region/sub-regional ALOS is significantly different from the national ALOS, after case-mix adjustment.
*** A shaded ratio implies that the RHA region/sub-regional percentage is significantly different from the national percentage, after case-mix adjustment.
"_" indicates no cases in 1994/95 and/or 1995/96 and/or 1996/97.
"#" indicates a percentage change of 1,000 percent or more.

Data source: NMDS public hospital data maintained by NZHIS (NZ Health Information Service). The data was extracted from the NMDS on 30 November 1997.
Data are filtered to exclude certain cases (e.g. well babies, transfers). See Appendix 2 for the full list of cases.
Time period covered - 12 months ending 30 June 1997.
ALOS = Average length of stay.
A small number of cases were not submitted to the NMDS (less than 0.1% of all discharges). These cases have not been included in calculations for both ALOS
and percent day case due to the lack of patient record information.
* A shaded ratio implies that the CHE ALOS is significantly different from the national ALOS, after case-mix adjustment.
** A shaded ratio implies that the CHE percentage is significantly different from the national percentage, after case-mix adjustment.
"_" indicates no cases in 1994/95 and/or 1995/96 and/or 1996/97.
"#" indicates a percentage change of 1,000 percent or more.

Data are filtered to exclude certain cases (e.g. well babies, transfers). See Appendix 2 for the full list of cases.
Time period covered - 12 months ending 30 June 1997.
SDR = Standardised discharge ratio.
ALOS = Average length of stay.
RHA totals and SDRs include services provided to publicly funded patients by private providers that were not submitted to the NMDS (less than 0.1% of all discharges),
and 'BD' cases (those which could not be assigned to a sub-region). These cases have not been included in calculations for both ALOS and percent day case
due to lack of patient record information.
* A shaded number implies that the RHA region/sub-regional rate is significantly different from the national rate.
** A shaded number implies that the RHA region/sub-regional ALOS is significantly different from the national ALOS, after case-mix adjustment.
*** A shaded ratio implies that the RHA region/sub-regional percentage is significantly different from the national percentage, after case-mix adjustment.
"_" indicates no cases in 1994/95 and/or 1995/96 and/or 1996/97.
"#" indicates a percentage change of 1,000 percent or more.

Data source: NMDS public hospital data maintained by NZHIS (NZ Health Information Service). The data was extracted from the NMDS on 30 November 1997.
Data are filtered to exclude certain cases (e.g. well babies, transfers). See Appendix 2 for the full list of cases.
Time period covered - 12 months ending 30 June 1997.
SDR = Standardised discharge ratio.
ALOS = Average length of stay.
RHA totals and SDRs include services provided to publicly funded patients by private providers that were not submitted to the NMDS (less than 0.1% of all discharges),
and 'BD' cases (those which could not be assigned to a sub-region). These cases have not been included in calculations for both ALOS and percent day case
due to lack of patient record information.
* A shaded number implies that the RHA region/sub-regional rate is significantly different from the national rate.
** A shaded number implies that the RHA region/sub-regional ALOS is significantly different from the national ALOS, after case-mix adjustment.
*** A shaded ratio implies that the RHA region/sub-regional percentage is significantly different from the national percentage, after case-mix adjustment.
"_" indicates no cases in 1994/95 and/or 1995/96 and/or 1996/97.
"#" indicates a percentage change of 1,000 percent or more.
