HEALTH SCREENING


MINDFULL MINUTE

  • Box Breathing

    • Box breathing is a mindfulness technique that helps to promote relaxation. It is similar to the 4-7-8 breathing technique but is shorter and incorporates visualization to aid the process.

    • Steps to Perform Box Breathing:

      • Visualize the left side of a two-dimensional square.

      • Inhale to the count of 4 while imagining moving to the top of the square.

      • Hold your breath for 4 seconds, envisioning yourself moving towards the right side of the square.

      • Exhale for 4 seconds while imagining going down the right side of the box.

      • Hold for another 4 seconds at the bottom of the box.

      • Repeat the process, doing a maximum of four rounds in one minute.


KARAKIA

  • A traditional Māori invocation or prayer used to honor the presentation of ideas and promote well-being:

    • Tuutawa mai i runga

    • Tuutawa mai i raro

    • Tuutawa mai i roto

    • Tuutawa mai i waho

    • Kia tau ai te mauri tuu

    • Te mauri ora

    • Ki te katoa

    • Haumi ee! Hui ee! Taiki ee!

    • Translation:

      • "Come forth from above, below, within, and from the environment. Vitality and wellbeing for all, strengthened in unity."


LEARNING OUTCOMES

  • Understand the concept and purpose of health screening.

WHAT WILL BE COVERED

Purpose of Health Screening

  • Health screening identifies individuals at risk for health conditions, enabling early intervention that leads to improved health outcomes.

Screening Methods

  • Understanding the differences between organized and opportunistic screening methods can highlight their respective benefits and potential risks.

Importance in Public Health

  • Health screening is a crucial component of public health, as it plays a vital role in disease prevention and management, promoting overall health in the community.

Application to Practice

  • Discussion on effectively applying health screening concepts in nursing and healthcare practice.


WHY SCREEN?

  • Purpose of Health Screening:

    • Screening helps identify individuals at risk before any symptoms appear, which is essential for timely health risk detection.

    • Early detection through screening leads to timely interventions and better health outcomes.

    • Reassurance:

      • Many participate in screening with the hope of reassurance regarding their health status, rather than anticipating that they may be diagnosed with a condition.

    • Important note: Screening does not provide a definitive diagnosis; it merely indicates risk levels.


BENEFITS OF SCREENING

  • Potential Benefits:

    • Screening programs can detect various conditions early, significantly reducing the risk of developing severe complications or mortality from conditions such as certain cancers.

    • Screening reduces overall healthcare costs and disease burden by enabling preventive care and fostering better prognoses.

    • Screening allows for early identification and treatment of diseases such as breast and cervical cancer before any symptoms manifest.

    • In newborns, screening can identify conditions that are treatable before preventable disabilities arise.


SOME EXAMPLES OF SCREENING IMPACT

  • Breast Screening:

    • Reduces mortality risk from breast cancer by approximately 30% for women aged 50-65 and by about 45% for women aged 65-69.

  • Cervical Screening:

    • Decreases the likelihood of developing cervical cancer by around 90%.

  • Newborn Hearing Screening:

    • Facilitates early detection of hearing loss, allowing for timely help including resources, parental support groups, hearing aids, cochlear implants, and early introduction to sign language.


ARE THERE ANY RISKS?

  • Risks Associated with Screening:

    • Screening tests may present risks of yielding false results:

      • False-Negative Result:

      • Occurs when an individual who has the condition is incorrectly deemed part of a low-risk group.

      • Can provide misplaced reassurance and delay necessary intervention and treatment.

      • False-Positive Result:

      • Happens when a person without the condition is categorized as having an increased chance of having it.

      • May lead to unnecessary anxiety and further diagnostic testing.


NURSING ROLE IN SCREENING

  • Educational Role of Nurses:

    • Nurses are crucial in educating and motivating patients to engage in screening programs, enhancing overall health benefits.

  • Facilitation Duties:

    • Nurses facilitate necessary health assessments for screening purposes.

  • Informed Consent:

    • Nurses must clearly communicate the risks of screening tests to patients to ensure informed consent and support patient decision-making processes.

  • Effective screening requires balancing the benefits against potential risks while managing patient expectations.


NATIONAL SCREENING UNIT

  • The National Screening Unit oversees the quality and equity of screening programs, ensuring adherence to evidence-based practices.

  • Scope and Focus:

    • Implements large-scale screening initiatives to guarantee health benefits across populations, emphasizing coordination and monitoring.

    • Breast, cervical, bowel, and newborn screenings are included, each with established criteria and follow-up procedures.

  • Ensures high standards in organized screening programs, with external evaluations monitoring service quality and consistency – providing uniform services, information, and support to all participants.


NATIONAL HEALTH COMMITTEE AND SCREENING

  • The National Health Committee authored criteria for evaluating potential new screening programs:

    • Condition Suitability: The health condition must be appropriate for screening.

    • Suitable Tests: There needs to be a reliable and effective test available.

    • Effective Treatments: An accessible and successful treatment or intervention should exist for identified conditions.

    • Evidence of Effectiveness: High-quality evidence demonstrating the screening program's impact on reducing morbidity and mortality is essential.

    • Benefit-Harm Balance: There should be a clear advantage of test benefits over any potential harms.

    • Support Capacity: The healthcare sector must be equipped to handle diagnosis, follow-ups, and program evaluations.

    • Social and Ethical Considerations: Must address social and ethical dilemmas pertaining to the screening.

    • Cost-Benefit Issues: An assessment of costs in relation to expected health benefits must be included.


HEALTH EQUITY FOCUS

  • Programs strive to ameliorate health inequities and enhance outcomes for specific populations including Māori, Pacific peoples, and marginalized communities.

  • Advisory Groups:

    • Engage committees like the National Screening Advisory Committee and the Māori Monitoring and Equity Group.

  • Cultural Alignment:

    • Align practices with Te Tiriti o Waitangi while working collaboratively with Māori communities to ensure culturally safe, family-centered care.

  • Targeted Outreach Efforts:

    • Identify and reach out to under-screened demographics using community navigators and improved contact approaches.

  • Culturally Appropriate Communication:

    • Provide educational materials in various languages and formats; tailor messages catering to Māori, Pacific, migrant, and refugee communities.

  • Accessible Services:

    • Offer mobile clinics, convenience with scheduling, transport assistance, and self-testing options to mitigate barriers faced by rural and low-income populations.

  • Workforce Development:

    • Train healthcare professionals in cultural competence and awareness of biases; recruit a diverse health workforce to foster trust in healthcare delivery.


2 TYPES OF SCREENING

  • Organized Screening:

    • Regularly scheduled tests, often mandated by health authorities for populations at risk.

  • Opportunistic Screening:

    • Screening provided during healthcare visits or initiated by health professionals due to patient requests or concerns.


2 GROUPS OF SCREENING RESULTS

Positive Screening Result

  • Indicates an increased likelihood of a condition; requires additional diagnostic testing for confirmation.

Negative Screening Result

  • Suggests a reduced likelihood of a condition; no immediate follow-up is necessary but may warrant future screenings.


WHAT NEXT?

  • Post-Screening Actions:

    • Individuals with a positive result will be referred for diagnostic testing to determine if a condition is present.

    • Those with a negative result typically won’t receive immediate follow-up testing but may be invited back for subsequent screenings.

    • Nurses should leverage screening outcomes to optimize communication, provide follow-up care, and support emotional well-being for patients.

    • Accurate screening methodologies and clear procedural guidelines are critical for managing patient safety and effective healthcare.


ORGANISED SCREENING PROGRAMMES

  • Individuals in New Zealand are encouraged to engage in organized screening initiatives funded based on identified high-risk population demographics.

  • The National Screening Unit manages and supervises nationwide organized screening initiatives:

    • Antenatal Screening: Includes evaluations for conditions such as Down syndrome and HIV during pregnancy.

    • BreastScreen Aotearoa: Offers free mammograms biennially for women aged 45-69 who meet eligibility criteria.

    • National Bowel Screening Programme: Distributes biennial faecal immunochemical tests (FIT), followed by colonoscopy if results indicate risk of bowel cancer.

    • National Cervical Screening Programme: Utilizes HPV screening, allows self-testing, and suggests follow-ups if HPV is present.

    • Newborn Metabolic Screening Programme: Heel prick tests performed to identify treatable metabolic disorders in infants within the first few days of life.

    • Newborn Hearing Screening Programme: Conducted prior to discharge from the hospital to catch hearing issues early.

  • This screening is available free of charge to all infants born in New Zealand, and while participation is optional, it is strongly advocated.

  • Residual Blood: Parents may opt to have leftover blood spots either returned or stored.


NEWBORN HEARING SCREENING PROGRAMME

  • Screenings are performed either before hospital discharge or at community clinics using methods such as automated auditory brainstem response (aABR) or otoacoustic emissions (OAE).

  • Babies failing initial screenings are referred for audiological assessments and early intervention measures.

  • All newborns in New Zealand are eligible for complimentary hearing screenings, with support extending through to school entry, including necessary follow-ups and amplification devices if indicated.


OPPORTUNISTIC SCREENING

  • Definition:

    • Occurs when an individual seeks advice from a healthcare professional for tests or checks, or the healthcare provider offers screening during consultations.

    • Common examples include prostate cancer screening and sexual health assessments.


OPPORTUNISTIC SCREENING DETAILS

Screening Type

Purpose and Rationale
  • Blood Pressure: Detects hypertension early, preventing stroke, heart attack, and kidney diseases.

  • BMI & Waist Circumference: Assesses weight status related to diabetes, heart disease, and cancers.

  • Cholesterol Testing: Identifies dyslipidaemia to avert cardiovascular issues and strokes.

  • Blood Glucose Testing: Screens for diabetes to prevent severe complications such as blindness and kidney failure.

  • Wellness Checks: Provides an overall health snapshot, helping to detect infections, cardiac issues, and metabolic imbalances.


WELLNESS CLINICS

  • Involves planned community events during Week 2 where health screening is conducted in various settings, including schools and police stations.

  • Typical measurements include:

    • Blood pressure,

    • Heart rate,

    • Respiratory rate,

    • Cholesterol,

    • Blood glucose,

    • Height,

    • Weight,

    • Body Mass Index (BMI),

    • Urinalysis (dependent on clinic specifics).


WHAT ARE WE SCREENING FOR?

  • Facilitators will encourage group discussions regarding the specific tests conducted at wellness clinics.

  • Key points to consider include:

    • The specific measurements each test evaluates,

    • Normal ranges for those measurements,

    • Significance of the test results to overall health.


BMI & WAIST CIRCUMFERENCE

  • Body Mass Index (BMI) Calculation:

    • Formula:
      extBMI=racextWeight(kg)extHeight(m)imesextHeight(m)ext{BMI} = rac{ ext{Weight (kg)}}{ ext{Height (m)} imes ext{Height (m)}}

    • Important note: BMI should primarily serve as a guideline, as it is unsuitable for individuals under 18 years, highly muscular individuals, pregnant women, or extremes in height (less than 1.5m or more than 1.9m).


BLOOD GLUCOSE MEASUREMENT

  • Capillary Blood Glucose Test:

    • A minimally invasive test providing results within 5 seconds.

    • Normal adult range: 4 - 7.5 mmol/L.

    • Report results indicating diabetes if:

      • >7.5 mmol/L (fasting) or

      • >11 mmol/L (postprandial, after eating).


CHOLESTEROL TESTING

  • Cholesterol Testing:

    • A minimally invasive test with a results turnaround of approximately 2 minutes.

    • Recommended ideal adult cholesterol levels: below 4 mmol/L; report any reading over 4.5 mmol/L for potential further testing.

    • High cholesterol levels are linked to increased risk of cardiovascular disease.


WELLNESS CLINIC PREPARATION

  • CLS Session:

    • To be conducted the Monday prior to the wellness clinic to prepare for all assessments, ensuring participants have time to practice.

  • Communication Preparation:

    • Practice communication methods with peers, family, and self-reflection in the mirror.
