Infections in the Long-Term Care Setting

Optimizing epidemic prevention in nursing homes using clinical surveillance of respiratory infections

Background

Respiratory tract infections (RTIs) pose a significant risk in nursing homes (NHs), which makes surveillance crucial for timely intervention.

Aim

To monitor the impacts of seasonal RTIs in NHs, which include frequency, the use of rapid diagnostic tests and antibiotics, mortality, and cluster dynamics, with the use of clinical surveillance.

Methods

During the winter periods from 2015 to 2019 (22 weeks), data on general signs (GSs), and respiratory signs (RSs) were collected to define three respiratory clinical sign patterns (CSPs): GS+/RS+, GS-/RS+, and GS+/RS-. Clusters (≥2 cases) were identified and classified into three intensity levels, namely, L1, L2, and L3 (2, 3-5, and ≥6 GS+/RS+/4 days, respectively). CSP frequencies and the 28-day all-cause mortality were calculated.

Findings

In 13 NHs (N = 3,628 resident inclusions, median age: 87.2 years), 1,538 GS+/RS+, 1,482 GS-/RS+, and 233 GS+/RS- cases were observed, with mortality rates of 8.5%, 2.8%, and 6%, respectively. Among the GS+/RS+ cases, 63% received an antimicrobials. GS+/RS+ cluster analysis identified 141 clusters with L1, 100 with L2, and 26 with L3.A total of 209 rapid diagnostic tests for influenza were carried out, with 72.2% conducted in L2 or L3 clusters. Within clusters, the first case must be identified promptly with rapid outbreak development taking place within the first 2-3 days, and potentially less effective containment efforts following delayed detection.

Conclusion

Clinical surveillance is a comprehensive method that can be utilized for the rapid implementation of preventive measures and appropriate use of antibiotics.

Infectious Diseases in Older Adults of Long-Term Care Facilities: Update on Approach to Diagnosis and Management

The diagnosis, treatment, and prevention of infectious diseases in older adults in long-term care facilities (LTCFs), particularly nursing facilities, remains a challenge for all health providers who care for this population. This review provides updated information on the currently most important challenges of infectious diseases in LTCFs. With the increasing prescribing of antibiotics in older adults, particularly in LTCFs, the topic of antibiotic stewardship is presented in this review. Following this discussion, salient points on clinical relevance, clinical presentation, diagnostic approach, therapy, and prevention are discussed for skin and soft tissue infections, infectious diarrhea (Clostridium difficile and norovirus infections), bacterial pneumonia, and urinary tract infection, as well as some of the newer approaches to preventive interventions in the LTCF setting.

Hand hygiene deficiency citations in nursing homes

Hand hygiene (HH) is recognized as an effective way to decrease transmission of infections. Little research has been conducted surrounding HH in nursing homes (NHs). In this research, deficiency citations representing potential problems with HH practices by staff as identified in the certification process conducted at almost all US NHs were examined. The aims of the study were to identify potential relationships between these deficiency citations and characteristics of the NH and characteristics of the NH environment. We used a panel of 148,900 observations with information primarily coming from the 2000 through 2009 Online Survey, Certification, And Reporting data (OSCAR). An average of 9% of all NHs per year received a deficiency citation for HH. In the multivariate analyses, for all three caregivers examined (i.e., nurse aides, Licensed Practical Nurses, and Registered Nurses) low staffing levels were associated with receiving a deficiency citation for HH. Two measures of poor quality (i.e., [1] Quality of care deficiency citations and [2] J, K, or L deficiency citations, that is deficiency citations with a high extent of harm and/or more residents affected) were also associated with receiving a deficiency citation for HH. Given the percentage of NHs receiving deficiency citations for potential problems with HH identified in this research, more attention should be placed on this issue.
