Hospitalization Rates for Respiratory Diseases After L'Aquila Earthquake

Area of Science:

• Public Health
• Epidemiology
• Environmental Health

Background:

• The 2009 L'Aquila earthquake significantly impacted the Abruzzo region, necessitating an examination of its public health consequences.
• Respiratory diseases represent a major health concern, and their incidence may be influenced by environmental stressors like seismic events.

Purpose of the Study:

• To investigate the impact of the earthquake on respiratory disease hospitalizations in the Abruzzo region, specifically within the earthquake-damaged "Crater" area.
• To analyze both short-term and medium-long term trends in hospitalizations for pneumonia, Chronic Obstructive Pulmonary Disease (COPD), and respiratory insufficiency.

Main Methods:

• Utilized Hospital Discharge Records (HDRs) for Abruzzo residents from 2009 to 2015, focusing on primary respiratory diagnoses.
• Calculated absolute frequencies and standardized hospitalization rates (SHRs) for different respiratory conditions.
• Employed linear regression analysis to assess trends in SHRs over time, comparing the "Crater" and non-Crater areas.

Main Results:

• Collected 108,669 respiratory-related records, with respiratory insufficiency being the most frequent diagnosis.
• Short-term analysis revealed a significant increase in hospitalizations for pneumonia and respiratory insufficiency in the Crater area post-earthquake.
• Medium-long term analysis indicated significant differences in the slope of hospitalization decrease for acute and chronic respiratory diseases between the Crater and non-Crater areas.

Conclusions:

• The earthquake may have acted as a trigger for increased detection and hospitalization for respiratory diseases in the affected region.
• A temporal association between the earthquake and elevated respiratory disease admissions was observed.
• While a direct cause-effect relationship remains to be definitively established, the findings suggest a link between the seismic event and respiratory health outcomes.
