COPD |Symptomatic Cases

Table 1 – COPD place among main death causes in developed countries

COPD |Symptomatic Cases

210 million people have COPD and 3 million people

died from COPD in 2005 corresponding to 5% of all

deaths globally. Meanwhile, COPD is predicted to be

the third leading cause of death worldwide by 2030.

COPD |Prevalence in Portugal

Table 1 – COPD prevalence in Portugal and its distribution according to age group and sex

Report from the portuguese national observatory of respiratory diseases

[4]Report from the portuguese national observatory of respiratory diseases 2009

Although COPD prevalence in the Portuguese Total number of admissions is not as significant as is in other countries, it is the second main cause of admissions to hospitals in cases of respiratory diseases;

Tobacco is the main cause of COPD (85% of cases).

The burden of disease attributable to smoking in Portugal

[9] Borges, M., M. Gouveia, et al. (2009).

The proportion of smokers in Portugal is of 20,2% in the general Total number of admissions over 15 years old.

About 14% of the burden of disease in wealthier countries is attributable to smoking

The effects of the anti-smoking law are yet to be analyzed.

ArticlesCOPD|

Socioeconomic Development Influence on COPD Mortality

[5] Chen, J., C. M. Schooling, et al. (2011).

Economic development may reduce vulnerability to COPD by reducing long-lasting

insults to the respiratory system, such as infections, poor nutrition and indoor air pollution.

Some of these gains may be offset if economic development results in increasing air

pollution or increasing smoking.

ArticlesCOPD|

[7] Han, M. K., D. Postma, et al. (2007).

[6] Patrascu, N. (2010).

Women may be at greater risk of smoking-induced lung function impairment for the same level of tobacco exposure.

Most studies have reported greater loss of lung function in women than men.

Differences exist between genders and this influences therapeutic management. Integrating this information is important to identify areas for future research.

Gender

ArticlesCOPD|

Gender

Chronic obstructive pulmonary disease (COPD) has historically been considered a

disease of older, white, male smokers.

In this study, the physicians more often diagnosed the women (incorrectly) as having

asthma, but the sex bias disappeared once they were shown spirometry results.

COPD |Justification

Prevalence in Portuguese Total number of admissions is not as significant as in other

countries

it is of extreme importance to determine how COPD have evolved in the last decade

No such synthesis study has yet been presented to the health care community in PORTUGAL

• Analyse and establish relationships between certain parameters

of COPD hospitalized patients’ such as:

Gender

Residency (related environmental factors)

Length of stay

Surgical procedures

Admission by year and seasonal variations

Influence of the 2007 smoke-free law

admissions of patients with COPD in portuguese public hospitals evolved over the last decade?
