Background: Effective bowel cancer screening is freely available in Australia, however, there are inequities in utilisation amongst non-English speakers at home. This study estimates the health impacts and cost-effectiveness of recruitment interventions targeted at Arabic and Mandarin speaking populations in Victoria, Australia to increase bowel cancer screening participation.

Methods: A Markov microsimulation model simulated the development of bowel cancer, considering National Bowel Cancer Screening Program participation rates.

Objective: Australia's National Bowel Cancer Screening Program (NBCSP) offers two-yearly screening to 50-74-year-olds for the prevention and early detection of colorectal cancer (CRC). Internationally, detailed reporting of participation across multiple screening rounds - also known as longitudinal adherence - is becoming more common, but remains limited in Australia. We described the longitudinal screening adherence of individuals by age and sex invited to the NBCSP at least once, and quantified longitudinal adherence among individuals who received four NBCSP invitations.

Article Synopsis
  • * Through qualitative interviews with various stakeholders, it was found that while trust in vaccines was high, many lacked understanding of the HPV vaccine, and barriers such as insufficient information, consent issues, and students' anxiety were prevalent.
  • * The research highlights the need for better communication and individualized support for students and parents, paving the way for future workshops aimed at improving vaccination uptake in these schools.

Article Synopsis
  • Australian guidelines suggest that individuals aged 50-70 should consider low-dose aspirin to lower colorectal cancer risk; this study aimed to assess whether a research consultation improves informed decision-making about aspirin use compared to a general prevention brochure.
  • Conducted at six general practices in Victoria, Australia, between October 2020 and March 2021, the study randomized 261 participants, comparing a decision aid consultation with a standard CRC prevention discussion.
  • Results showed that 17.7% of the intervention group made informed choices about taking aspirin by the first month, compared to 7.6% in the control group; however, at the six-month mark, aspirin uptake between the two groups was similar with 10.2% in the

Article Synopsis
  • - Australia has high colorectal cancer rates, and participation in its National Bowel Cancer Screening Program (NBCSP) is low, particularly among those aged 50-60.
  • - Previous research (SMARTscreen) showed that sending SMS messages with motivational content increased participation by 16.5% compared to standard practice.
  • - The new SMARTERscreen trial will evaluate whether sending just an SMS or an SMS with online videos can further boost NBCSP participation among patients aged 49-60, using a randomized controlled design across 63 general practices.

Article Synopsis
  • Young women aged 25-35 in Australia have lower cervical screening rates than older women, prompting a study to identify factors impacting their screening behavior.* -
  • The research utilized focus groups and an online survey, revealing that past negative experiences, practitioner interactions, prioritization of screening, and knowledge about cervical screening significantly influence young people's behavior.* -
  • The study highlights the need for tailored public health campaigns and improved communication strategies in clinical settings to address the specific barriers faced by this age group.*

Article Synopsis
  • - In early 2020, the Australian Government implemented COVID-19 measures that disrupted cancer screening programs for breast, bowel, and cervical cancers, prompting an evaluation of these impacts on cancer outcomes.
  • - The study modeled outcomes over 3, 6, 9, and 12-month disruptions, predicting a decrease in breast (9.3%) and colorectal cancer diagnoses (up to 12.1%), while cervical cancer diagnoses could increase (up to 3.6%), highlighting the potential for more advanced disease stages.
  • - Findings emphasize the importance of maintaining screening participation to minimize the long-term burden of cancer, providing crucial insights to inform decision-making and enhance future screening programs.

Objectives: This field study evaluated a multiwave media campaign that aired in 2019 to promote participation in the Australian National Bowel Cancer Screening Program (NBCSP), which provides free biennial mailed-out immunochemical faecal occult blood test (iFOBT) kits to Australians aged 50-74 years.

Design: Adjusted negative binomial regression models determined rate ratios of iFOBT kits returned during and following three campaign waves compared with 2018 (baseline). Interaction terms determined whether effects differed by gender×age group, socioeconomic status (SES) and previous participation.

Objective: Colorectal cancer has geographic inequities in Australia, with higher mortality rates and lower participation in the National Bowel Cancer Screening Program (NBCSP) in remote and rural areas. The at-home kit is temperature-sensitive, necessitating a 'hot zone policy' (HZP); kits are not sent when an area's average monthly temperature is above 30°C. Australians in HZP areas are susceptible to potential screening disruptions but may benefit from well-timed interventions to improve participation.

Background: Australian guidelines recommend that all people aged 50-70 years old actively consider taking daily low-dose aspirin (100-300 mg per day) for 2.5 to 5 years to reduce their risk of colorectal cancer (CRC). Despite the change of national CRC prevention guidelines, there has been no active implementation of the guidelines into clinical practice.

Introduction: With almost 50% of cases preventable and the Australian National Bowel Cancer Screening Program in place, colorectal cancer (CRC) is a prime candidate for investment to reduce the cancer burden. The challenge is determining effective ways to reduce morbidity and mortality and their implementation through policy and practice. -Bowel is a multistage programme that aims to identify best-value investment in CRC control by integrating expert and end-user engagement; relevant evidence; modelled interventions to guide future investment; and policy-driven implementation of interventions using evidence-based methods.

Objective: To examine the effect of a mass media campaign designed to increase bowel cancer screening participation.

Methods: We assessed weekly participation, from January 2015 to December 2017, in the Australian National Bowel Cancer Screening Program in Victoria, where a seven-week campaign aired in mid-2017, and in the adjacent comparison state of South Australia. Participation, defined as the number of immunochemical faecal occult blood tests returned out of those invited by the Screening Program in the past 16 weeks, was analysed using negative binomial regression.

Objectives: Participation in the Australian National Bowel Cancer Screening Program (NBCSP) is suboptimal. Given the program's enormous potential to save lives, Cancer Council Victoria has prioritised increased screening participation as part of its strategic plan. This paper describes the implementation, and evaluation where available, of Cancer Council Victoria programs to increase participation, supported by a mix of own organisation and Victorian state health department funding.

Objectives And Design: This field experiment aimed to compare bowel cancer screening participation rates prior to, during and after a mass media campaign promoting screening, and the extent to which a higher intensity campaign in one state led to higher screening rates compared with another state that received lower intensity campaign exposure.

Intervention: An 8-week television-led mass media campaign was launched in selected regions of Australia in mid-2014 to promote Australia's National Bowel Cancer Screening Program (NBCSP) that posts out immunochemical faecal occult blood test (iFOBT) kits to the homes of age-eligible people. The campaign used paid 30-second television advertising in the entire state of Queensland but not at all in Western Australia.

The study assessed whether a mass media campaign could encourage women who were overdue for a Papanicolaou (Pap) test to have one, without prompting unnecessary early re-screening. A telephone survey of a representative sample of 1000 Victorian women aged 25-65 years assessed recall of the advertisement and intention to act after seeing it. The television advertisement was recalled by 61.
