Foreword Victorian Nurse Cervical Screening Providers - Certification Program 2017 The world of cervical screening underwent a significant change in 2017 with the commencement of the Renewed National Cervical Screening Program on 1 December. The implementation of the new program also brought about changes to what was previously known as the Credentialling Program for Nurse Cervical Screening Providers and the transition into the new Certification Program for Victoria. Cancer Council Victoria (Cancer Council) has continued to support and value the role of Victorian Certificated Nurse Cervical Screening Providers in 2017, the twenty first year of the program. The successful maintenance of the significant role of nurses in cervical screening through transition in Victoria has been supported by the Department of Health and Human Services (DHHS), VCS Pathology and the Victorian Cervical Screening Registry (VCSR) to ensure that nurses’ role in cervical screening remains identifiable as the transition of data to the National Cancer Screening Register continues. Nurses that complete their endorsed Victorian training course are granted Certification as cervical screening providers and are eligible to access a ‘practice number’ with VCS Pathology. As of December 2017, the program had 504 certified nurses providing cervical screening in Victoria. The quality of nurses’ practice has been reported by VCSR annually since 2000. Victoria remains the only Australian state or territory that has nurse collected cervical screening data reported. The VCSR Nurses Evaluation Report 2017 is the fourth edition in which data from all Victorian nurses providing cervical screening have been reported, regardless of pathology provider used. The outcome of this report continues to demonstrate the close working relationship between VCSR and Cancer Council. We would like to acknowledge their shared commitment to showcasing cervical screening undertaken by Victorian nurse cervical screening providers.

1. Number of Cervical Screening Tests (CSTs) collected by nurses
This report includes data on Cervical Screening Tests (CSTs) collected by nurses who are certified and funded by the DHHS to be eligible for their own ‘practice number’ at VCS Pathology. Also included in this report are CSTs from nurses using Private Pathology Services. These nurses provide cervical screening data to Cancer Council, which is then provided to VCSR for analysis and inclusion in this report. The report captures all CST reported in Victoria, including those conducted as part of the Compass study. The Compass study is a clinical trial comparing two and a half yearly cytology screening with five yearly Human Papillomavirus (HPV) based screening.1 The Pilot study commenced at the end of 2013 and the Main trial commenced at the start of 2015. Since 2014, data from the study have been included in this report. Data in this report include: 1. All cytology and LBC2 tests (as usually reported) that are not part of Compass 2. All LBC primary screening tests conducted as part of Compass 3. LBC triage tests for Compass 4. Compass HPV primary screening tests for which there is no LBC triage Due to the introduction of the renewed National Cervical Screening Program (Renewal) on 1 December 2017, all of the data in this 2017 report are for the period 1 January 2017 to 30 November 2017 only. As of 1 December 2017 CST has been used in the renewed cervical screening program to refer to a primary HPV test with reflex cytology where required. The term CST in this report is not used in the same way, with most CSTs in this report being conventional or liquid based cervical cytology specimens. As reported to VCSR, a total of 27,015 CSTs were collected by 419 nurses during January to November 2017 (with 26,801 from women with a cervix). This is from a total of 515,513 Victorian CSTs for the same 2017 period (with 507,960 from women with a cervix). Of the CSTs reported by nurses, 23,836 tests (88.2%) were reported to VCS Pathology. The remaining 3,179 tests (11.8%) were taken by nurses and reported by Private Pathology Services under a doctor's name. The 27,015 tests collected by nurses represent 5.2% of all Victorian CSTs collected between January and November 2017. As shown in Table 1.1 and Figure 1.1, the number and proportion of tests collected by nurses has declined since 2013. However, the number still remains more than seven times higher than the figure recorded in 1996.

3. Type of practice/organisation for nurses Of the CSTs collected by nurses during 20176, the majority were conducted in General Practice or in a Community Health setting. The combined proportion of CSTs collected in General Practice or in a Community Health setting has remained stable at 87.2% compared to 87.1% in 2016. There was a small increase in collection by nurses located in General Practice and Private Pathology Services between 2016 and 2017.

4. Practice and woman location at time of CST During January to November 201710, 419 nurses performed CSTs in Victoria. The VCSR recorded 387 certified nurses whose tests were reported by VCS Pathology. Cancer Council provided the details of 32 additional unique nurses whose CSTs were reported to the Registry through Private Pathology Services under a doctor’s name. The geographical location of nurses (by practice) and the women whose CSTs were collected by a nurse during the 2017 period are classified below using the Australian Statistical Geography Standard (ASGS) Remoteness Areas. The ASGS Remoteness Areas classification was developed by the Australian Bureau of Statistics (ABS), and classifies areas of Australia which share common characteristics of remoteness into broad geographical regions. The ASGS Remoteness Areas classification divides Australia into five areas:11 • Major Cities of Australia: includes capital cities such as Melbourne, as well as major urban areas such as Geelong • Inner Regional Australia: includes towns such as Ballarat, Bendigo and Shepparton • Outer Regional Australia: includes towns and cities such as Bairnsdale and Horsham • Remote Australia: includes towns such as Mallacoota and Ouyen • Very Remote Australia: represents much of central and western Australia and includes towns such as Tennant Creek, Longreach and Coober Pedy Using the ASGS classification, Table 4.1 shows that the majority of nurses who collected CSTs during the 2017 period were based in a major city or inner regional area, as were the women tested.

5. Proportion of CSTs collected by nurses by Department of Health and Human Services (DHHS) area The Victorian DHHS operates across the state from within seventeen local areas, of which nine are in rural Victoria and eight in metropolitan Melbourne. The table and map below show that, consistent with previous years, nurses collected a higher proportion of CSTs in rural areas than in metropolitan areas. The proportion of CSTs collected by nurses increased by almost 2% and 3% respectively in the Mallee and Ovens Murray areas in 201715.

6. Socio-Economic Index for Areas (SEIFA) Socio-Economic Index for Areas (SEIFA)20 is a summary measure developed by the Australian Bureau of Statistics (ABS), which includes a suite of four indexes that have been created from social and economic Census information. Each index ranks geographic areas across Australia in terms of their relative socio-economic advantage and disadvantage. This report uses the Index of Relative Socio-economic Disadvantage (IRSD), which is a general socio-economic index that summarises a range of information about the economic and social conditions of people and households within an area. The ABS broadly defines relative socioeconomic advantage and disadvantage in terms of people’s access to material and social resources and their ability to participate in society.21 Index of disadvantage scores have been grouped into quintiles (1 to 5) for analysis. The highest quintile (5) represents the highest 20% of postcode scores (20% of the population) and includes the least disadvantaged areas. The lowest quintile (1) represents the lowest scores and the most disadvantaged areas. As seen in both the table and figure, almost 60% of women screened by nurses during 201719 are categorised in the most disadvantaged quintiles (1 and 2).

7. Age distribution of CSTs The age distribution of women whose CSTs was collected by nurses and other provider types is shown in Table 7.125 26. Other provider types include GPs, obstetricians and gynaecologists and hospital clinics. A comparison of 2016 and 201722 data show the percentage of CST for each age group to be similar for both nurses and other provider types. Consistent with the findings for 2016, the aggregated percentage of CSTs collected by nurses during 201722 for women aged 50 years or older was greater than those collected by other provider types (43.5% compared with 33.7%).
22
2017 data is for the period 01/01/2017 to 30/11/2017 only 436 women could not be aggregated into SEIFA quintiles, as there was no postcode to Postal Area match in the concordance file (1) or postcode was interstate (435). NB: SEIFA calculations are based on women with a Victorian postcode only. 24 Due to the rounding of percentages, there may be some discrepancy in totals 25 Age range for Compass trial participants is 25-64 years 26 Analysis is based on the number of tests, not the number of women 23

8. Endocervical status The presence of endocervical cells within a cytology test specimen is considered to be a reflection of smear quality. Of the technically satisfactory cytology tests collected by nurses from women with a cervix in 201729, 71% were reported as including an endocervical component. The proportion of cytology tests with an endocervical component for other provider types during the same time period was 66%. The graph below shows that the proportion of cytology tests collected by nurses having an endocervical component, which had slightly increased in 2016, declined again in 2017. The proportion for other provider types has continued to decrease during 2017. Over the decade prior to 2013, a general decline in the proportion of cytology tests with an endocervical component has been observed across all provider types. Preliminary investigation indicates that the decline is likely to be due to the increasing use of liquid based cytology (LBC) in the time period, with lower rates detected in LBC specimens compared to conventional. This could be due to practitioners lacking familiarity with robust techniques for ensuring cervical cells are effectively transferred into the liquid media and cytology screeners lacking familiarity with identifying these cells in LBC samples.30

9. Profile of CSTs The following tables show the result categories for CSTs collected by nurses and other provider types during 201732. Note that cytology tests and HPV (without LBC) tests are shown in separate tables. Table 9.1 shows the cytology test result categories for tests collected by nurses and other provider types during 201732 for women with a cervix. Compared with Victorian cytology tests collected by other provider types, nurses had a significantly higher proportion of tests with negative results (p<0.0001) and a significantly lower proportion of unsatisfactory tests (p<0.0001). In addition, nurses had a lower proportion of high-grade results (p=0.021).

10. Time since previous screening The following table shows the length of time since any previous CST, as known to the Registry, for tests collected by nurses during 201737. Compared with CSTs collected by other Victorian provider types, and similar to the findings of 2016, a higher proportion of CSTs were collected by nurses where the time interval since the last test was between 21-27 months (on time for a two year screening interval) (p<0.0001). There was also strong evidence (p< 0.0001) that nurses were more likely than other providers to collect CSTs from those whose last test was greater than 48 months ago.

11. Collection of Aboriginal and Torres Strait Islander status, Country of Birth and Language Spoken at Home The Victorian Cancer Plan 2016-2020 recognises that there are inequities for Aboriginal Victorians across the entire cancer pathway including cancer screening. The plan seeks to achieve equitable cancer outcomes for Aboriginal communities. It is acknowledged that there is now improved cancer screening program participation for under screened groups including Aboriginal communities.40 41 For a number of years now, the nurses who work with VCS Pathology have recorded Aboriginal and Torres Strait Islander status on the VCS Pathology Request Forms. The standard nationally approved format used on data collection forms is as follows:42 • • • •
Aboriginal but not Torres Strait Islander origin Torres Strait Islander but not Aboriginal origin Both Aboriginal and Torres Strait Islander origin Neither Aboriginal nor Torres Strait Islander origin

The overall percentage of CSTs collected by nurses for which an Aboriginal and Torres Strait Islander status was reported in 201743 was 96.1%, a decrease of 1.1% from 97.2% in 2016. The distribution of Aboriginal and Torres Strait Islander status for the women that had a CST collected by nurses has remained consistent between 2016 and 201743. Since the data collection expansion to include Country of Birth and Language Spoken at Home, the collection of this additional information continues to assist with understanding and addressing the screening needs of women from culturally diverse backgrounds.

In 201747, the overall percentage of CSTs recorded by nurses for which Language Spoken at Home was collected was 93.4%. The most common Non-English languages were as follows (most common first): Vietnamese, Khmer, Mandarin, Chinese (not elsewhere classified), Arabic, Greek, Italian, Karen, Cantonese and Filipino. The overall percentage of CSTs recorded by nurses for which Country of Birth was recorded was 95%. The most common countries of birth outside of Australia were as follows (most common first): Vietnam, Cambodia, England, China (excludes SARS and Taiwan), Myanmar, New Zealand, Philippines, India, United Kingdom (includes Channel Islands and Isle of Man) and Italy. VCSR continues to work closely with VCS Pathology and Cancer Council to capture these data items on the registry database from nurse notifications, including from nurses who use Private Pathology Services. Figure 11.2 below represents the continued success in the recording of Aboriginal and Torres Strait Islander status, Language Spoken at Home and Country of Birth. The high percentage figures shown illustrate the strong commitment to complete data collection by nurses involved in cervical screening.

12. Conclusion There were 419 active certified nurses collecting CSTs in Victoria during 201748. Of these, 387 reported CSTs directly to VCS Pathology and the remaining 32 reported to the Registry through other Private Pathology Services under a doctorâ&#x20AC;&#x2122;s name. During 201748, the number of tests collected by these certified nurses and reported to the Registry was 27,015 tests (88.2% reported through VCS Pathology and 11.8% reported through Private Pathology under a doctorâ&#x20AC;&#x2122;s name). The CSTs collected by nurses represented 5.2% of all CSTs performed that year, which was a slight reduction from 5.4% in 2016. General Practice and Community Health settings continued to represent the main practice/ organisation types where nurses collected CSTs. There was also a slight increase in collection by nurses based at other practice types including General Practices and Private Pathology services. The majority of nurses who collected CSTs, and Victorian women who had CSTs collected by nurses, during 201748 were located in major cities or inner regional areas of Victoria. In 201748 nurses continued to collect a higher proportion of tests from women over the age of 50 years than other provider types. Although a general downward trend has been observed over the last decade, the proportion of cytology tests with an endocervical component continued to be higher for nurses than other provider types during 201748. The data in this report highlight the important role that nurses have in the success of the Victorian Cervical Screening Program, particularly in relation to the rising number of CSTs performed by them over the past two decades and the high quality of their tests. Also of note is the commitment of nurses to complete data collection, which assists with identifying and meeting the needs of under screened groups.
