The goal of this clinical trial is to assess efficacy of an intensive pre-surgical
intervention to quit smoking in smoking patients who will be operated on implant
orthopedic surgery or general and urological surgery. The main question[s] it aims to
answer are:

  -  Evaluate the efficacy of intensive pre surgical intervention to quit smoking
     compared to a brief intervention

  -  Evaluate the implementation of this protocol.

Participants will be randomized to 2 intervention groups (patients programmed for
protesic implant orthopedic surgery in the first group, and general and urological
surgery) and 2 control groups (stratified in the same manner as the intervention groups),
and will be monitored through telematic check ups via phone calls.

Intervention for Smoking Cessation in Pre-Surgical Patients.

Smoking

Smoking Cessation

Surgical Procedure, Unspecified

1. Subject recruitment in pre surgical anesthesiology consults, data collection and
     randomization within 48 hours of said visit.

  2. Subjects in the intensive intervention group will be sent to a specialized
     Preventive Medicine consult for smoking cessation, completing 6 visits (2 before
     surgical intervention, 4 visits withint the following 12 months). Subjects in the
     control group will receive brief advice on quitting smoking through a phone call the
     the same day randomization is performed. Both groups will receive follow up calls at
     months 1, 3, 6, and 12, after surgical intervetion. All patients will have their
     smoking habits evaluated and the relevant data about the surgical intervention
     collected the day of the intervention.

  3. At month 7 adecuacy of the protocol will be evaluated to assess if any modifications
     are necessary.

  4. Data entry and quality control of the database will be performed periodically for
     the duration of the study.
