COVID-19 Case Rates After Surveillance and Vaccinations in a Statewide Psychiatric Hospital System.

Area of Science:

• Public Health
• Infectious Disease Epidemiology
• Mental Health Services

Background:

• Individuals with serious mental illness (SMI) face heightened vulnerability to COVID-19.
• Psychiatric hospitals require targeted strategies to mitigate viral transmission.
• The COVID-19 pandemic posed a significant risk to institutionalized populations.

Purpose of the Study:

• To evaluate the effectiveness of public health interventions in reducing COVID-19 spread within New York State psychiatric hospitals.
• To assess the impact of rapid testing, quarantine, and vaccination on infection rates in inpatients and staff.
• To provide evidence for prioritizing these interventions in similar healthcare settings.

Main Methods:

• Implementation of rapid COVID-19 testing for patients and staff.
• Mandatory quarantine protocols for exposed individuals.
• Rollout of vaccination programs for eligible patients and staff.
• Monitoring of infection rates from November 2020 to February 2021.

Main Results:

• A 96% decrease in COVID-19 infection rates among inpatients.
• A 71% decrease in COVID-19 infection rates among staff.
• A 6% decrease in the overall New York State population case rate during the study period.

Conclusions:

• Rapid testing, quarantine, and vaccination are highly effective in controlling COVID-19 outbreaks in psychiatric hospitals.
• These interventions should be prioritized to protect vulnerable individuals in state-operated mental health facilities.
• Successful implementation demonstrates the feasibility and impact of comprehensive infection control measures.
