Team approach to infection prevention and control in the nursing home setting

Effectiveness of Infection Control Teams in Reducing Healthcare-Associated Infections: A Systematic Review and Meta-Analysis

The infection control team (ICT) ensures the implementation of infection control guidelines in healthcare facilities. This systematic review aims to evaluate the effectiveness of ICT, with or without an infection control link nurse (ICLN) system, in reducing healthcare-associated infections (HCAIs). We searched four databases to identify randomised controlled trials (RCTs) in inpatient, outpatient and long-term care facilities. We judged the quality of the studies, conducted meta-analyses whenever interventions and outcome measures were comparable in at least two studies, and assessed the certainty of evidence. Nine RCTs were included; all were rated as being low quality. Overall, ICT, with or without an ICLN system, did not reduce the incidence rate of HCAIs [risk ratio (RR) = 0.65, 95% confidence interval (CI): 0.45-1.07], death due to HCAIs (RR = 0.32, 95% CI: 0.04-2.69) and length of hospital stay (42 days vs. 45 days, p = 0.52). However, ICT with an ICLN system improved nurses' compliance with infection control practices (RR = 1.17, 95% CI: 1.00-1.38). Due to the high level of bias, inconsistency and imprecision, these findings should be considered with caution. High-quality studies using similar outcome measures are needed to demonstrate the effectiveness and cost-effectiveness of ICT.

Systematic Review of Interventions to Reduce Urinary Tract Infection in Nursing Home Residents

BACKGROUND

Urinary tract infections (UTIs) in nursing homes are common, costly, and morbid.

PURPOSE

Systematic literature review of strategies to reduce UTIs in nursing home residents.

DATA SOURCES

Ovid MEDLINE, Cochrane Library, CINAHL, Web of Science and Embase through June 22, 2015.

STUDY SELECTION

Interventional studies with a comparison group reporting at least 1 outcome for: catheter-associated UTI (CAUTI), UTIs not identified as catheter-associated, bacteriuria, or urinary catheter use.

DATA EXTRACTION

Two authors abstracted study design, participant and intervention details, outcomes, and quality measures.

DATA SYNTHESIS

Of 5794 records retrieved, 20 records describing 19 interventions were included: 8 randomized controlled trials, 10 pre-post nonrandomized interventions, and 1 nonrandomized intervention with concurrent controls. Quality (range, 8-25; median, 15) and outcome definitions varied greatly. Thirteen studies employed strategies to reduce catheter use or improve catheter care; 9 studies employed general infection prevention strategies (eg, improving hand hygiene, surveillance, contact precautions, reducing antibiotics). The 19 studies reported 12 UTI outcomes, 9 CAUTI outcomes, 4 bacteriuria outcomes, and 5 catheter use outcomes. Five studies showed CAUTI reduction (1 significantly); 9 studies showed UTI reduction (none significantly); 2 studies showed bacteriuria reduction (none significantly). Four studies showed reduced catheter use (1 significantly).

LIMITATIONS

Studies were often underpowered to assess statistical significance; none were pooled given variety of interventions and outcomes.

CONCLUSIONS

Several practices, often implemented in bundles, such as improving hand hygiene, reducing and improving catheter use, managing incontinence without catheters, and enhanced barrier precautions, appear to reduce UTI or CAUTI in nursing home residents. Journal of Hospital Medicine 2017;12:356-368.

Impact of infection preventionists on Centers for Medicare and Medicaid quality measures in Maryland nursing homes

BACKGROUND

Health care-associated infections are the leading cause of morbidity and mortality in US nursing homes (NHs). The objective of the research is to assess the impact of Maryland NH infection preventionists (IPs) on NH quality measures.

METHODS

Two hundred thirty-four NHs were queried through mailed survey. These survey data were then linked with 2008 quality data from Nursing Home Compare and the On-line Survey Certification of Automated Records.

RESULTS

Three of the 8 quality measures examined-influenza vaccination for both short- and long-stay residents and pressure ulcer prevention in high-risk residents-were significantly associated with the number of IPs. None of the quality measures were shown to be significant with IPs who received specialized training on infection prevention and management compared with those who did not receive specialized training.

CONCLUSION

IPs play a critical role in preventing and managing health care-associated infections in nursing homes, especially in the areas of influenza vaccination and pressure ulcer prevention among high-risk nursing home residents. Quality measures that reflect the effects of IP training may not have been elucidated yet. Further research is needed to support the IP role in order for policy to advocate for increased IP funding.

Hand Hygiene Practices Reported by Nurse Aides in Nursing Homes

Information from nurse aides describing their opinions of hand hygiene practices in nursing homes including perceived barriers to hand hygiene is presented. The information comes from a questionnaire developed for this investigation, with items addressing compliance, facility guidelines and protocols, training, hand washing facilities and materials, and hand washing barriers. Information from 4,211 nurse aides (response rate of 56%) working in a nationally representative sample of 767 nursing homes (participation rate = 51%) is used. We find that 57.4% of nurse aides comply with hand washing when caring for residents most of the time, while 21.7% always comply. With facilities, 43.3% sometimes check that hand washing is performed. In summary, self-reported compliance was poor, and facilities and materials were often lacking. These findings are useful in identifying issues and interventions, including the need for further initiatives to address hand hygiene practices.

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.

Common infections in nursing homes: a review of current issues and challenges

Over 1.5 million people live in 16,000 nursing homes in the USA and experience an average of 2 million infections a year. Infections have been associated with high rates of morbidity and mortality, rehospitalization, extended hospital stay and substantial healthcare expenses. Emerging infections and antibiotic-resistant organisms in an institutional environment where there is substantial antimicrobial overuse and the population is older, frailer and sicker, create unique challenges for infection control. This review discusses the common infections, challenges, and a framework for a practical infection prevention program.

Nursing home deficiency citations for infection control

BACKGROUND

This study examined the deficiency citation for infection control (ie, F-Tag 441). This information represents potential problems in infection control as identified in the yearly certification process of almost all US nursing homes.

METHODS

The data used came primarily from the Online Survey, Certification, and Reporting data base, which contains information on both deficiency citations and characteristics of nursing homes. The data for each nursing home from 2000 through 2007 were combined, providing a panel of 100,000 observations. Multivariate analyses and generalized estimating equations with a logit link were used.

RESULTS

An average of 15% of all nursing homes received a deficiency citation for infection control each year from 2000 to 2007. In the multivariate analyses, several staffing levels were robust in their significance. For all 3 types of caregiver examined (ie, nurse aides, Licensed Practical Nurses, and Registered Nurses), low staffing levels were associated with receipt of a deficiency citation for infection control.

CONCLUSION

The high number of deficiency citations for infection control problems identified in this study suggests the need for increased emphasis on these programs in nursing homes to protect vulnerable elders.

Preventing antimicrobial-resistant bacterial infections among older adults in long-term care facilities

For older adults in long-term care facilities (LTCFs), the rate of infections caused by antimicrobial resistant strains of bacteria has increased and is prompting renewed interest in investing health care resources for prevention and control of these pathogens. This document offers a simple framework to combat infections due to antimicrobial resistant bacteria in LTCF residents by providing a multi-step approach consisting of four major strategies: prevent infection, diagnose and treat infection effectively, use antimicrobials wisely, and prevent transmission. Recommendations from this multi-step approach are directed at LTCF medical directors and practicing clinicians involved with the medical care of older adult LTCF residents.

Infections and the elderly

Epidemiology Aging is a natural process and a part of our lives, but nowadays there is an increase in the number of persons aged 65 and over. Today infectious diseases are still responsible for one-third of all deaths in the world. The elderly population is most vulnerable to serious infections and at greatest risk for death and complications. Among geriatric population pneumonia and influenza are the fourth most common cause of death Vaccination One of the goals of preventive medicine is to reduce the rate of complications and mortality from infectious diseases by increasing immunization rates. Influenza and pneumococcal vaccines are indicated for persons aged 65 and over. Despite well-recognized benefit of such vaccination, less than 50% of eligible patients receive the vaccine each year. Infections Older persons generally have increased susceptibility to infections because of multiple risk factors and they are the most vulnerable population to nosocomial and health-care associated infections. Older persons may manifest infectious diseases atypically, with acute confusion or delirium which can lead into delay in diagnosis and therapy. It is important to know that the older present with delayed or poor response to antimicrobial therapy and high rates of adverse reactions to drugs, including antibiotics Conclusion As elderly population is rapidly growing, majority of patients with serious or life-threatening infections are old. Geriatric issues have not typically been a focus of training in infectious diseases, but we must become aware of and knowledgeable about special and unique aspects of infections in this population.

Sharps injury recordkeeping activities and safety product use in California health care facilities: pilot study results from the sharps injury control program

BACKGROUND

In 1999, licensed health care facilities in California (N = 2532) were invited to participate in a survey about occupational bloodborne pathogens exposure surveillance activities, recordkeeping methods, and use of safety-enhanced sharps devices.

RESULTS

A total of 1274 facilities responded to the survey from January 1999 through August 1999 (response rate = 50%). Sharps-related injuries were recorded for multiple departments on various forms in diverse manners. Only 66% of hospitals, 37% of home health agencies, and 33% of skilled nursing facilities reported sharps injuries on a mandated sharps injury log. More than 70% of facilities stated that they used some type of safety device or needleless system, but this figure varied by type of device and facility type. Eighty-four percent of general acute care hospitals, 28% of home health agencies and skilled nursing facilities each had evaluated at least 1 safety-enhanced device. Almost 90% of all facilities expressed a need for educational materials on topics such as device selection and evaluation.

CONCLUSIONS

Standardization of surveillance and recordkeeping activities does not exist across facility types. Standards and regulations demand complex recordkeeping activities. Increased funding for distribution of educational materials and on-site training should accompany changes in mandated reporting activities when appropriate. Increased testing and evaluation of devices across facility types are necessary to ensure that safety-enhanced devices are protective of health care workers and patients.

Infections in residents of long-term care facilities: an agenda for research. Report of an expert panel

The number of frail, older residents of long-term care facilities (LTCFs) will increase dramatically over the next 30 years. Improving the quality of health care provided in LTCFs is an important national and international priority. Improving the prevention and management of infections in LTCFs is a critical component of efforts to improve quality of care and poses unique challenges. This report summarizes the presentations and discussions of participants in an invitational conference to propose a research agenda for prevention and management of infections in LTCFs. The conference was held in March 2001 in Atlanta, Georgia. The discussants identified key research questions to better understand general issues involving the overall burden of infections in LTCFs, prevention and control interventions, and antimicrobial use and resistance. The participants also discussed research questions involving specific infections, including pneumonia and urinary tract, skin, and soft tissue infections. Recommendations for research were discussed and are presented in summary form in this report. Improving the prevention and management of infections in LTCF residents should be a priority if quality of care in these facilities is to be improved. Many unanswered questions remain in this field, and the research agenda outlined in this report will require resources and focus. The benefit of such efforts to LTCF residents and their caregivers is likely to be substantial.

Emerging health care-associated infections in the geriatric population

The increasing number of persons >65 years of age form a special population at risk for nosocomial and other health care-associated infections. The vulnerability of this age group is related to impaired host defenses such as diminished cell-mediated immunity. Lifestyle considerations, e.g., travel and living arrangements, and residence in nursing homes, can further complicate the clinical picture. The magnitude and diversity of health care-associated infections in the aging population are generating new arenas for prevention and control efforts.
