  1. Smoking cessation for diabetes patients by primary health care nurses – how well are we doing? Dr Barbara Daly, Prof. Bruce Arroll, A/P Nicolette Sheridan A/P Timothy Kenealy Acknowledgements Primary health care nurses of Auckland Novo Nordisk Diabetes Ministry of Health (New Zealand) Charitable Trust of the Auckland Faculty of the Royal NZ College of GPs

  2. Background - diabetes • Large increase in the incidence of type 2 diabetes from 124,000 in 2001 to • 205,000 (6%) in 2012/13 adult survey1 • Large increase for Pacific peoples from 10% to 13%1 • 7% for both Māori and Asian populations1 • Shortage of health professionals to manage the condition2,3 • Expanded roles for primary health care (PHC) nurses4 • Practice nurses (largest group) • District nurses • Specialist nurses • Diabetes Nurse Specialists (DNS) & • Chronic Care Management (CCM) nurses • Nurse practitioners

  3. Diabetes patients who smoke have poorer cardiovascular outcomes • CV events,5 • Chronic kidney disease & its progression6,7 • Peripheral vascular disease8 • Lower limb amputations8

  4. PHC nurses survey 2006-8Aims • Identify the key issues for PHC nurses in the management of diabetes • Describe the role played by PHC nurses, and compare the different nurse groups • Describe their knowledge of diabetes management • Identify training needs for PHC nurses

  5. Methods Cross-sectional survey • 287 PHC nurses randomly sampled • 26% of total PHC nurses • 86% response rate (representative of all nurses) • 210 Practice nurses (PNs) • 49 District nurses (DNs) • 28 Specialist nurses (SNs) • Completed postal & telephone questionnaires on education, experience, knowledge & management • Information also collected on 265 diabetes patients consulted on a randomly selected day

  6. Results Knowledge of risk factors for diabetes / complications9 • 96% of nurses identified excess body weight • 89% retinopathy Knowledge of risk factors for complications • 86% elevated HbA1c / BGLs • Only 17% identified smoking • Only 14% stroke • Lack of associations between knowledge of, and assessment of CV risk factors  

  7. Awareness of diabetes complications – by nurse group9 P-values: * * *<0.001; * *0.01; * <0.05

  8. Awareness of risk factors for diabetes-related complications – by nurse group9 P-values: * * *<0.001; * *0.01; * <0.05

  9. Prevalence of smoking in diabetes patients slightly less than population Tobacco use (n=264)10 • Smokers 16% (More for DNs patients) • Non-smokers 81% • Not known 3% (more for DNs patient)

  10. Management of smoking cessation10 • Patients consulted by DNs were more likely to smoke • Patients >66 years less likely Of those who wished to stop: • Only 50% were offered nicotine replacement therapy.

  11. Conclusions • PHC nurses esp. practice & district nurses need to increase their knowledge of CV risk factors. • Measurement of blood pressure and advice on diet, physical activity and smoking cessation were not related to patient’s cardiovascular risk. • Primary health care nurses are ideally placed to develop capability and expertise in smoking cessation. • Further education and training for nurses. • Need more research on nurse-led smoking intervention trials to test if more effective than usual care 

  12. Discussion points Latest three large intensive glucose control trials11-13 • Smoking rates halved by the end of the trial periods in both groups (authors not sure why). • Focus was on lowering glucose not smoking. • People who know they are at a higher risk of poor outcomes are more likely to make quit attempts and stop.14-16
