Introduction:

COVID-19, a respiratory infection caused by SARS-CoV-2, has demonstrated varying severity across populations, with approximately 20% of patients developing complications and less than 5% experiencing severe disease requiring hospitalization. The impact of chronic diseases on COVID-19 outcomes remains particularly relevant in developing countries, where healthcare resources and population characteristics differ from well-studied settings.

Objective:

Describe the clinical and epidemiological characteristics of patients hospitalized with COVID-19 during the first seven months of the pandemic in Paraguay, analyzing how chronic non-communicable diseases (NCDs) influenced disease progression and outcomes.

Material and

Methods: We conducted a cross-sectional analytical study examining medical records from patients hospitalized with confirmed SARS-CoV-2 infection across five major referral hospitals in Paraguay from March to September 2020. Using bivariate and multivariate logistic regression analyses with likelihood ratio criterion, we identified factors associated with ICU admission and mortality, considering p<0.05 statistically significant.

Results:

Among 1,690 hospitalized patients, 797 (47.2%) met inclusion criteria, with a median age of 51 years and male predominance (53.8%). Chronic diseases were present in 61.9% of patients, with hypertension (29.6%) and diabetes (25.6%) being most prevalent. Multivariate analysis revealed that age over 80 years (OR=7.70), presence of COPD (OR=2.58), and having three or more NCDs (OR=2.78) significantly increased mortality risk. ICU admission was required for 29.6% of patients, with an overall mortality rate of 29.1%.

Conclusion:

The severity of COVID-19 outcomes among hospitalized patients in Paraguay showed strong associations with advanced age, multiple chronic conditions, and specific comorbidities like COPD. These findings emphasize the need for targeted preventive strategies and enhanced monitoring of high-risk patients, particularly those with multiple NCDs.
