Supplementary file 1_An outlook on clinical and demographic variables in patients with sev

1,425 patient records from two high-specialty hospitals in Mexico City and Merida, collected from March 2020 to November 2022. The retrospective study by Ingrid Fricke-Galindo compares variables like hospital stay length and ventilation rates across six pandemic waves and SARS-CoV-2 variants. Differences in patient demographics and outcomes, such as a median 23-day hospital stay during the 2nd and 3rd waves, are documented.

Use Cases

• Compare clinical outcomes like mortality and invasive mechanical ventilation rates across pandemic waves.
• Analyze the association between patient comorbidities, such as heart disease, and severe COVID-19 during specific variant stages.
• Study the impact of vaccination status on mortality and other variables during the Omicron wave.
• Model hospital resource utilization based on variables like length of stay and ventilation requirements over time.

Strengths

• Includes 1,425 patient records from two specialized hospitals.
• Covers a significant time range of over two and a half years (March 2020–November 2022).
• Compares specific variables like median hospital stay (23 days) and invasive mechanical ventilation rates (81.02%) across defined pandemic waves.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count for specific sub-analyses (e.g., per wave) is unknown, which may limit suitability assessment.
• The 46.6 KB file size suggests a limited scope, likely containing summary or processed data rather than raw patient-level records.
