INTRODUCTION: BACKGROUND
Narrowing and hardening of arteries
Decreased blood flow
PAD
Difficulty in walking, rest pain, ulceration, lower extremity amputation,
death.
Risk Factors
Hypertension Hypercholesterolemia
Diabetes Smoking

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.
Aims
1. Quantify how frequently patients with PAD know about smoking as a cause and a prognostic of their condition.
2. Determine when and by whom were they warned about this fact.
3. Find out whether people in this state have changed or not their smoking habits due to the provided information.
• (If they have) Find out if the severity of the disease altered.
Participants and Methods
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.
Our exclusion criteria are:
Patients unable to consciously communicate;
Patients who do not agree to get involved in this study.
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)
Present
Past FutureInformed Not Informed
Data collecting methods
Structured interviews will be done to patients suffering from PAD, who are admitted in the Vascular Surgery Department of Hospital de São João.
Variables description
Personal data of PAD patientsDiabetes;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;
Variables description
PAD risk factors awarenessAwareness 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.
Variables description
Behaviour changes 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.
Statistical analysis/Expected results
Scholar degree and the awareness of the risk factors;
Time of risk factors awareness and date of PAD
diagnostic;
Change of smoking habits (type of change) and state
of the disease after that behaviour change (evolution
of the disease).
