NHSN 海急性醫院（ACH）年報

HAI/AR 計劃每年都會發布報告，為醫療機構和預防應對措施提供信息，以幫助減少弗吉尼亞州急診醫院 (ACH) 患者的醫療相關感染 (HAI)。

醫療保健相關感染（HAI），以前稱為醫院感染，是在接受醫療護理時所感染的感染。患者可以從例行護理、手術、使用呼吸器或導管等醫療設備的併發症，或是過度使用抗生素的副作用。

有關更多信息，請參閱「導航」部分下發布的鏈接。

指南

Data collected for the years of 2022-2025 were downloaded from the National Healthcare Safety Network (NHSN) on September 4, 2026. Any changes made to the data after this date are not reflected in the results. This one-time retrieval was necessary to incorporate the updated 2022 baseline, which replaced the previously used 2015 baseline.

Note: Data for 2019–2021 are not displayed in this dashboard because they are not available using the updated 2022 baseline. Historical data for these years (using the 2015 baseline) may be requested by emailing hai@vdh.virginia.gov.

The 2025 NHSN Patient Safety Component Annual Hospital Survey was used to gather information on hospital characteristics (e.g., hospital bed size and medical school affiliation).

定義：

VDH Health Planning Region

There are five public health planning regions in Virginia (Central, Eastern, Northern, Northwest, Southwest). The health planning regions allow public health to conduct surveillance and assess health needs across different areas of Virginia.

Healthcare Coalition Region

The Virginia Healthcare Emergency Management Program was created through a partnership between VDH and the Virginia Hospital & Healthcare Association (VHHA), enhancing hospital and healthcare system capabilities to respond and recover from a wide range of public health and healthcare emergencies. VDH and VHHA work with hospitals and healthcare facilities through a regional structure that consists of four healthcare coalitions (Central, Eastern, Northern, Southwest). More information is available on the VDH Hospital and Healthcare Preparedness page.

Hospital System

醫院系統或醫療保健系統是由中央組織擁有、贊助或合同管理的兩家或多家醫院。

Medical School Affiliation

Medical school affiliation equals ‘Yes’ if the hospital answered ‘Yes’ to the following question on the NHSN Patient Safety Component Annual Hospital Survey: Is your hospital a teaching hospital for physicians and/or physicians-in-training? Includes major teaching (facility has a program for medical students and post-graduate medical training (i.e., residency and/or fellowships), graduate teaching (facility has a program for post-graduate medical training, i.e., residency and/or fellowships only), or undergraduate (facility has a program for medical students only).

Bed Size

Bed size is defined as the number of beds set up and staffed in all inpatient locations.

Standardized Infection Ratio (SIR) = Number of observed infections / Number of predicted infections

The standardized infection ratio (SIR) is a summary measure that can be used to track HAIs over time and can be calculated on a variety of levels, such as unit, facility, state, and nation. The SIR adjusts for differences between hospitals, such as types of patients and procedures, as well as other factors. SIRs indicate whether the observed number of infections is higher, lower, or similar to the predicted number of infections based on national baseline data from 2022.

In the dashboard, the “SIR interpretation” adds information so the user knows if the SIR is statistically significant:

 If the SIR interpretation is 更好, then the number of observed infections was significantly lower than the number predicted.
 If the SIR interpretation is 相同, then the number of observed infections did not significantly differ from the number predicted.
If the SIR interpretation is 更糟, then the number of observed infections was significantly higher than the number predicted.
 If the SIR interpretation is 沒有結論, then the SIR was not calculated because the number of predicted infections was less than 1.

Standardized Utilization Ratio (SUR) = Number of observed device days / Number of predicted device days

標準化的使用率比率 (SUR) 可衡量設備使用率，並且是可擴展、風險調整後的量度，可以在不同地點和設施進行比較。根據 2022 的國家基準數據，SUR 指出觀察到的設備天數是否更高、更低或類似於預測的設備天數。

針對急診醫院的非 NICU 位置，中央線路和導管 SURS 會根據設施類型、醫學院附屬性、住院病床數和患者照護地點類型進行風險調整。NICU 地點中央線路的 SUR 會根據設施類型、醫學院所屬性、住院病床數、NICU 類型（II/III 級與第三級）以及 NICU 患者的出生重進行調整。

FAQs: NHSN 2022 HAI Rebaseline

醫護人員流感疫苗接種

‘Healthcare personnel’ and ‘healthcare workers’ are used interchangeably. ‘Influenza’ and ‘flu’ are used interchangeably. 

Percentage of healthcare personnel (HCP) in each hospital who were vaccinated during each influenza season (October 1-March 31), starting with the 2022-2023 influenza season. Healthcare personnel include employees, licensed independent practitioners, and adult students/trainees and volunteers.  

The U.S. Department Health and Human Services (HHS) and Healthy People 2020 previously established a 90% influenza vaccination target for healthcare personnel. This target was removed under Healthy People 2030, which established a 70% vaccination target for all individuals in the U.S. aged 6 months and older.

Despite the change in national targets, The Advisory Committee on Immunization Practices (ACIP) and the CDC continue to recommend annual influenza vaccination for all healthcare personnel to reduce the risk for influenza and influenza-related morbidity and mortality for healthcare personnel and their patients.

For more information about each hospital’s HCP flu vaccination percentage, hover over the bars in the graph.
Use the filters in the menu to view data for certain hospitals.
To highlight HCP flu vaccination percentages that are Better, Same, or Worse, click the highlighter button to the right of ‘Comparison to HHS Goal’ and then select one of the categories.
