  1. Peripheral Arterial Disease Class 5, 1st year 2009/2010 Adviser: Sérgio Sampaio Patients’ awareness of smoking as a risk factor

  2. Narrowing and hardening of arteries INTRODUCTION: BACKGROUND • Decreased blood flow • PAD • Difficulty in walking, rest pain, ulceration, lower extremity amputation, death. McDermott MM. Cleve Clin J Med. 2006. Remes L, et al. 2008. Gutacker N, et al. 2009. • Zanati SG, etal. Clinics. 2009.

  3. Risk Factors Criqui MH. Vasc Med. 2001. Selvin E. et al. Circulation. 2004.

  4. Awareness of smoking as a risk factor Hirsch AT et al. Circulation. 2007.

  5. Justification • We decided to evaluate the awareness of smoking as a risk factor because: • People, most of the times, cannot control the expression of diabetes, but it is their choice to smoke or not to; • There is a low community consciousness of this risk factor.

  6. Justification • It will be important to know the awareness of the Portuguese PAD patients to this modifying risk factor, because that way it will be easier to define strategies to improve the communication and to try to make people change their smoking habits.

  7. Research Question • How aware are patients with PAD regarding smoking as a major risk factor?

  8. Aims • Quantify how frequently patients with PAD know about smoking as a cause and a prognostic of their condition. • Determine when and by whom were they warned about this fact. • Find out whether people in this state have changed or not their smoking habits due to the provided information. • (Iftheyhave) Findoutiftheseverityofthediseasealtered.

  9. Participants and Methods Our exclusion criteria are: • Patients unable to consciously communicate; • Patients who do not agree to get involved in this study. • Our target population are Portuguese patients suffering from PAD who are admitted in a hospital. • Our inclusion criterion is the patients with PAD being admitted in the Vascular Surgery Department of Hospital de S. João.

  10. Participants and Methods

  11. Study design • Analytic retrospective cohort: • patients who were informed of tobacco as a risk factor with patients who were not (cohort) • events that happened in the past (retrospective): • try to establish the relations among them (analytic) Past Future Present

  12. Data collecting methods • Questionnaires were done to patients suffering from PAD, who were admitted in the Vascular Surgery Department of Hospital de São João.

  13. Sample • Exclusion criterion: • Patients unable to consciously communicate.

  14. Variables description Personal data of PAD patients • Diabetes; • Hypertension; • Hypercholesterolemia; • State of the disease at the time of the diagnosis, according to Lerishe-Fontaine classification; • Current state of the disease; • Date of PAD diagnosis; • Smoking habits;

  15. Variables description PAD risk factors awareness • Awareness of: • Diabetes; • Hypercholesterolemia; • Hypertension; • Smoking; • Knowledge sources; • If the information was given by a doctor, another variable we decided to put was the specialty of the doctor . • Time of risk factors awareness.

  16. Variables description Behaviourchanges after awareness of PAD risk factors: • Change of smoking habits; • Way of change; • Number of attempts, if the interviewed patient tried to quit smoking without success.

  17. Statistical analysis/Expected results • Scholar degree and the awareness of the risk factors; • Time of risk factors awareness and date of PAD diagnosis; • Change of smoking habits (type of change) and state of the disease after that behaviour change (evolution of the disease).

  30. Observations • After20days, wehavea smallsample (N=28). Therefore, theresultsweachievedwerenotstatiscallysignificantandthereis no variabilityamong some data. • Wewerenotable to relate some importantvariables, such as Change of smoking habits (type of change) and State of the disease after that behaviour change (evolution of the disease).
