Screening and Diabetes Type II Becky Ellis, RN, BSN
ScreeningThe process of detecting unrecognized disease in otherwise healthy populations
Mass Screening Applied to entire populations • 1981 screening for elevated blood lead levels all adults within state • 1970 screening for cervical cancer on women admitted to hospitals within state • PKU testing on all newborns
Selective Screening • Targets specific high-risk populations • Mammograms recommended more frequently for women with a family history of breast cancer • PPD for hospital personnel
Multiphasic Screening • A variety of screening tests applied to the same population on the same occasion • Includes a series of tests on a single vial of blood • Pre-op work-ups, periodic health assessment and for monitoring the stage of an illness.
Case-Finding Screening • A Search for illness done during an individuals periodic health assessment • Pap Smears and Breast Exams for women • Testicular Examinations for men • The Denver Developmental Screening Test
Appropriateness of Screening • Health problem with serious consequences e.g. Diabetes • Must be cost effective or have positive health outcomes • PAP Smears result in possible cure • PKU Screening can prevent mental retardation
To be Beneficial • Screening should result in a better prognosis • The screening process should be effective in reducing morbidity and mortality • The prevalence of the health problem is high in the population • Should be quick, easy and noninvasive when possible
The Health Problem: • Have a high prevalence in the population • Be relatively serious • Be able to be detected in early stages • Have an effective treatment that improves outcomes
The Screened Group: • Be identifiable • Be assessable • Accept the screening procedures • Be willing to seek treatment • Accept follow-up procedures
The Screening Test: • Cost effective • Simple, safe, and easy to administer • Of minimal discomfort • Sensitive enough to detect most cases • Specific to the health problem • Valid and reliable
Sensitivity and Specificity • Sensitivity • Populations who have the health problem are correctly identified • Specificity • Populations who do not have the health problem are correctly identified
Predictive Value • Frequency with which the health problem is correctly identified among those screened
Yield • Previously unrecognized cases of the disease that is identified during the screening process
Newly Diagnosed Cases of Diabetes by Year • Steady Increase since 1997 CDC October 2003
Screening Tests Type II Diabetes • Fasting Plasma Glucose (FPG) • Two Hour post-load plasma glucose (2 hour GTT) • Glycosylated hemoglobin A1c (HbA1c)
ADA Recommendations for Screening • Fasting Plasma Glucose (FPG) • Faster to perform • More convenient • Acceptable to patients • Less expensive
Other ADA Recommendations for Diabetes Screening • Selective Screening based on risk factors • Age>45 • BMI>25 • Family History • Habitual physical inactivity • Race/Ethnicity e.g. African Americans, Hispanic-Americans, Native Americans, Asian-Americans, and Pacific Islanders • Previously identified impaired fasting glucose or impaired glucose tolerance
Selective Screening • Recommended that Clinicians use the ADA’s guidelines for selective screening of at-risk individuals
Nursing Implications: Diabetes Type 2 Tori L. Reid, RN BSN
Learning From Listening: The Article • Qualitative research from CDC, taped interviews, themes • 235 Participants, 2002 • Screened to have risk factors • Formal and informal community leaders invited by recommendations
Five Themes • Attributions for Diabetes: “American lifestyle”, “don’t sweat”, biological risk factors, stress, poor eating habits, lack of physical exercise • Reactions to findings confirming benefits of lifestyle interventions for diabetes prevention: encouraging and hopeful, common sense, modest recommendations, but wont be easy
Five Themes Continued • Awareness of the potential for preventing or delaying diabetes as a motivator for action: realistic fear can play a role, rewards must be connected to meaning, social support is critical, consistency with cultural or historical values, children need to be taught healthy lifestyles early
Five Themes Continued • Barriers to change: lack of time, fast food and sedentary entertainment, high cost of nutritional food, lack of family support, environmental constraints, lack of awareness about diabetes, diabetes not a priority in some communities
Five Themes Continued • How people want to be told if they have prediabetes: straightforward but with gentle, hopeful approach, simple explanations, knowing can be empowering, tied to hope
What Can We Do? • Social Support • Message design: use staging and visual teaching tools • Gain exposure and attention: “turn up the volume” • Identifying message appeal: hope dispels fatalism
What Can We Do? • Accordance with values, belief and history: memories matter
Historic/Current Approaches • Screenings: clinics, physician’s office, work, mall, social groups • Follow-up: • Education: public, hospital, physician’s office, formal education programs, internet, • FOCUS ON SECONDARY/TERTIARY
Current/Future Approaches • Division of Diabetes Translation (DDT): “charged with developing and implementing a public health response to the rising burden of diabetes in the United States” • Goal: “reduce the burden of diabetes through collaborations with diabetes prevention and control programs (DPCP)”
Current/Future Approaches • Plans: strengthen public health surveillance systems for diabetes, conduct applied translational research, implement the National Diabetes Control Program, implement the National Diabetes Education Program, and coordinate media strategies and provide public information
Discussion • What have you seen? • What are you doing? • Where can we improve? • Community programs in place now?
