Summary
COVID-19 research needs multi-center data. A privacy-preserving web portal analyzed data from 202 hospitals, finding no significant mortality differences by gender or ethnicity after age adjustment.
Area of Science:
- Clinical Medicine
- Public Health
- Health Informatics
Background:
- Urgent need for COVID-19 clinical course insights.
- Multi-center data crucial but centralization challenging.
- Privacy-preserving methods enable distributed research.
Approach:
- Launched a public Questions & Answers web portal (https://covid19questions.org).
- Analyzed comorbidities, medications, and lab tests.
- Utilized data from 202 hospitals (59,074 COVID-19 patients) in USA and Germany.
Key Points:
- 8.6% of non-ICU hospitalizations led to readmission within seven days.
- Hospitalized COVID-19 patient mortality showed no significant difference by gender or ethnicity, adjusted for age.
- Comorbidities, medications, and lab tests were analyzed.
Conclusions:
- Distributed data analysis is feasible for COVID-19 research.
- Web portals can facilitate multi-center data insights.
- Key clinical outcomes like readmission rates and mortality factors were identified.

01:26Principles of Disease Surveillance
369
Disease surveillance is the systematic collection, analysis, and interpretation of health data essential to the planning, implementation, and evaluation of public health practice. This process integrates data dissemination to entities responsible for preventing and controlling disease, injury, and disability. Surveillance systems provide crucial information for action, helping public health authorities make informed decisions to manage and prevent outbreaks, ensure public safety, optimize...

In the ever-evolving field of public health, statistical analysis serves as a cornerstone for understanding and managing disease outbreaks. By leveraging various statistical tools, health professionals can predict potential outbreaks, analyze ongoing situations, and devise effective responses to mitigate impact. For that to happen, there are a few possible stages of the analysis:

The American Nurses Association (ANA) created and implemented the first nationally accepted Code of Ethics for Nurses with Interpretive Statements. The Code of Ethics is a living document regularly updated by the ANA and establishes an ethical standard that is non-negotiable for nurses in all roles and settings.
The Code of Ethics provisions outline the nurse's duty to the patient, the healthcare team, the profession, and society. The Code's fundamental principles include advocacy,...

01:09Censoring Survival Data
417
Survival analysis is a statistical method used to analyze time-to-event data, often employed in fields such as medicine, engineering, and social sciences. One of the key challenges in survival analysis is dealing with incomplete data, a phenomenon known as "censoring." Censoring occurs when the event of interest (such as death, relapse, or system failure) has not occurred for some individuals by the end of the study period or is otherwise unobservable, and it might have many different...
