    neon.= neonatal.

    Only NSW residents are included. Rehabilitation episodes are excluded. Figures are based on where a person resides, rather than where they are treated. Hospital separations were classified using ICD-10-AM. Rates were age-adjusted using the Australian population as at 30 June 2001.

    A recent policy change (PD2017_015) resulted in patients treated solely within the emergency department being excluded from this indicator report. Please note that a minority of patients being managed in short stay areas of emergency departments are still included. Further information is found in a paper in the HealthStatsPLUS Methods tab on this website.

    ICD10-AM chapters on diseases of the nervous system, eye and ear and chapters on conditions relating to pregnancy, perinatal period and congenital diseases are combined into one category in the analysis. ICD10-AM chapter Factors influencing health has been divided into two categories: Dialysis and Other factors influencing health in the analysis. 

    Numbers for recent years include an estimate of the small number of hospitalisations of NSW residents in interstate public hospitals, data for which were unavailable at the time of production. Further details can be found in the Methods tab in the following HealthStats NSW indicator: http://www.healthstats.nsw.gov.au/Indicator/bod_hos_cat

    LL/UL 95%CI = lower and upper limits of the 95% confidence interval for the point estimate.

      Haemorrhoids were classified as diseases of the circulatory system under ICD-10-AM Seventh edition (I84). In ICD-10-AM Eighth edition haemorrhoids are classified with diseases of the digestive system (K64). Consequently, haemorrhoids are not included in the total count of diseases of circulatory system.

    • Key points: Hospitalisation

      • Over the 10 years between 2008-09 and 2017-18, the number of hospitalisations has increased in NSW by 32% (from  2,259,212 in 2008-09 to 2,986,204 in 2017-18) but the age-standardised hospital rate has increased by only 13% (from 30,816 per 100,000 population in 2007-08 to 34,862 per 100,000 population in 2017-18). Age-standardisation adjusts for the  impact of the known effect of an ageing population on increasing hospitalisation rates over time.

      • Age-standardised hospitalisation rates for females are consistently higher than those for males over time and were 7% higher than males in 2017-18. 

      • Apart from population ageing and differences in the age structures of population groups (such as Aboriginal peoples and those living in rural areas), rates of hospitalisation are influenced by the incidence (new cases) and prevalence (existing cases) of chronic and acute disease and injury in the population, availability of and access to health services, and availability of treatment options for diseases and injuries.

    • Introduction: Hospitalisation

      Definition

      The term 'hospitalisation' refers to a period of time during which a person stayed in a hospital for a defined purpose, which could be diagnostic, curative or palliative. A hospital stay starts with a formal process of admission and ends with a formal separation.

      Hospitalisations are described in hospital statistics, which measure hospital activity. The number of patients in a period of time, number of beds, types of beds (for acute or chronic cases etc) and bed occupancy levels are measured among other variables. These statistics are compared to staffing levels, available funds and population size and are used to monitor the distribution and utilisation of hospital services. Hospitalisations can also be analysed by a patient's demographic and clinical characteristics such as their age and their clinical diagnosis.

      Sources of data in NSW

      Sources of data on hospitalisations in NSW include the NSW Combined Admitted Patient Epidemiology Data (CAPED) and NSW Population Health Survey.

      In HealthStats NSW, hospitalisations are analysed on the basis of separations (i.e. the date the person completed that hospital episode, rather than the date that person was admitted into that hospital episode). The reason for this is that the coding of a patient's clinical diagnosis during a hospitalisation is done after separating from that hospital. This diagnosis may be different from the reason the person was admitted. Expert medical coders decide on the principal and associated diagnoses after separation based on the whole medical records of the patient.

    • Interventions: Hospitalisation

      Interventions aiming to reduce hospitalisation rates are embedded in strategies dealing with specific health issues or specific disadvantaged populations.

      These strategies focus on reduction of prevalence of conditions in the community (prevention of conditions arising in the first place) or on reduction of hospitalisations for these conditions via two different methods. One method focuses on preventing worsening of conditions and managing these conditions via primary care system and thus preventing admission to hospital. The topic of Potentially Preventable Hospitalisations (Ambulatory Care Sensitive Conditions) contains a discussion of details concerning these conditions. The NSW Chronic Care Program covers many such conditions requiring hospitalisation.

      The other approach reduces the burden of hospitalisations on the health system by reducing the number of beds required at any point in time. It is based on the concept of out-of-hospital care, which includes hospital care at home. NSW Ministry of Health delivers an increasing type and number of services in out of hospital environment.
