Hospital patient experiences of contact isolation for antimicrobial resistant organisms in relation to health care-associated infections: A systematic review and narrative synthesis of the evidence

BACKGROUND

The alarming growth of antimicrobial resistance organisms (AMRs) and the threat caused by health care-associated infections require hospitalized individuals who are infected or colonized with AMRs to be cared for in isolation, predominantly in single rooms. None of the existing reviews focus on or specifically address the patient's experience of being cared for in contact isolation when affected by AMRs exploring this specific context.

METHODS

Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidance for the conduct of systematic reviews was applied. Five databases were searched from inception to April 2019, with keywords related to adult patient experiences, AMR, and contact isolation. The evidence was certified by 2 reviewers. Principles of thematic analysis were used to produce a narrative synthesis of the findings.

RESULTS

Eighteen eligible studies were identified. Narrative synthesis resulted in 3 overarching categories reflecting the patient experience: privacy versus loneliness; emotional responses to isolation; quality of care, recovery, and safety in isolation.

CONCLUSIONS

This review synthesizes existing evidence reflecting the patient experience of contact isolation. Study findings were often contradictory and may not reflect contemporary health care, such as shorter hospital stays, or societal preferences for greater privacy. Further research focusing on contemporary health care contexts is recommended.

[Respiratory infections: Additional transmission-based precautions in healthcare facilities]

INTRODUCTION

In health care, measures against cross-transmission of microorganisms are codified by standard precautions, and if necessary, they are supplemented by additional precautions.

STATE OF THE ART

Several factors impact transmission of microorganisms via the respiratory route: size and quantity of the emitted particles, environmental conditions, nature and pathogenicity of the microorganisms, and degree of host receptivity. While some microorganisms necessitate additional airborne or droplet precautions, others do not.

PROSPECTS

For most microorganisms, transmission patterns are well-understood and transmission-based precautions are well-established. For others, measures to prevent cross-transmission in healthcare facilities remain under discussion.

CONCLUSIONS

Standard precautions are essential to the prevention of microorganism transmission. Understanding of the modalities of microorganism transmission is essential to implementation of additional transmission-based precautions, particularly in view of opting for appropriate respiratory protection.

Comparison of knowledge and awareness of infection control practices among nurses in India: A cross-sectional survey

BACKGROUND

Healthcare-associated infections (HAIs) are a significant threat in healthcare settings. Since nurses have the most day-to-day contact with patients, their knowledge about infection control (IC) practices is crucial in preventing HAIs. We therefore conducted a study to assess the knowledge and awareness of IC practices amongst nurses across hospitals in India.

METHODS

An online survey-based, cross-sectional, descriptive study for nurses was conducted in July-August 2021, through a multiple-choice questionnaire, administered via a web-based link across 13 hospitals from various cities of India. Five different aspects of IC knowledge were assessed including general IC, standard precautions, transmission-based precautions, bundle care knowledge, and COVID-19 related knowledge.

RESULTS

Complete data filled by 1,000 nurses was analyzed. The knowledge of nurses varied across different aspects of IC. A statistically significant association was found between the IC knowledge and the years of experience (P = .003) and the area of working (critical vs semi-critical areas) (P < .001) of nurses. A statistically significant difference was also found in the knowledge of nurses from different hospitals depending upon the accreditation (P < .001) and the teaching status (P = .035), but no significant difference based on the city category of hospital (P > .05). Accreditation showed the strongest association {β = 2.499 (95% CI = 1.67-3.32)} while non-teaching status had a negative impact {β = -1.76 (95% CI = 2.543 to -2.543)} on knowledge using multivariate linear regression analysis.

CONCLUSIONS

Infection prevention and control is the biggest challenge in any hospital and improving the knowledge and awareness of the nurses on the same is fundamental to its success. A multifaceted approach of continuing education programs, training, and feedback should be undertaken towards improving the awareness and compliance to IC practices.

Lessons learned from a failed implementation: Effective communication with patients in transmission-based precautions

BACKGROUND

Patient engagement with transmission-based precautions can be an important strategy to prevent adverse events related to isolation. Most patient education is still highly prescriptive and is thus unlikely to help. Effective communication requires behavior change, leading to a meaningful dialog between the parties involved.

OBJECTIVE

evaluate implementation process of a protocol for effective communication with patients in transmission-based precautions (Com-Efe).

METHODS

Implementation research using qualitative methods in 4 sequential phases: (1) nonparticipant observation in inpatient wards; (2) design of the intervention for implementation; (3) adaptation of the Com-Efe through workshops with nurses; (4) final assessment of the implementation results through interviews with nurses. Study was performed in a public, secondary, teaching hospital. Consolidated Framework for Implementation Research was used as the reference for interview design and data analysis, aiming to identify barriers and enablers of the implementation process.

RESULTS

Main factors that could have facilitated adherence were beliefs and perceived advantages in using the Com-Efe by nurses. Main barriers that may have contributed to the failure were the unfavorable climate for implementation, insufficient individual and leadership commitment, and the lack of understanding of the concepts underpinning effective communication.

CONCLUSIONS

Despite using a systematic approach, the Com-Efe protocol was not fully implemented. The lessons learned in this study allowed us to propose suggestions for future protocol implementations in similar contexts.

The lived experience of haemodialysis patients managed with transmission-based precautions for MDRO colonisation: A qualitative study

BACKGROUND

Patients undergoing haemodialysis colonised with multi-drug resistant organisms (MDROs) are commonly managed with transmission-based precautions (TBP) to prevent nosocomial transmission. TBP have been linked to mixed effects on patient psychological well-being and clinical care. This study was designed to report the lived experience of dialysis patients managed with TBP.

METHODS

A qualitative study of 15 patients undergoing haemodialysis managed with TBP was performed. Participants took part in individual semi-structured interviews. Data was analysed utilising an interpretive phenomenological approach.

RESULTS

Four themes were identified. 1. Communication of what MDRO screening meant, the results, and implications of MDRO positivity was perceived by many patients as insufficient and inconsistent. 2. Experiences of care in isolation were described, with both positive (privacy) and negative (reduced interaction) experiences identified. 3. Psychosocial and emotional responses including concern about health implications and stigma were reported, but also screening was described by some as increasing their perception of being cared for by health care workers, as they felt all health risks were being managed. 4. Confusion around perceived inconsistencies of management, particularly across different environments (eg hospital vs home) and staff.

CONCLUSION

TBP have complex positive and negative impacts on patients which should be considered when developing MDRO management policy and communication around such policy. Strategies to improve communication, patient and staff education, and remove (or explain) perceived inconsistencies of practice may reduce the negative consequences of TBP leading to improved delivery of quality, person-centred care.

The authors also discuss lessons learned from nosocomial transmission events.

Paediatric nurses', children's and parents' adherence to infection prevention and control and knowledge of antimicrobial stewardship: A systematic review

INTRODUCTION

Infection prevention and control precautions help to decrease microbial transmission, and through the appropriate use of antibiotics, Antimicrobial Stewardship programs aim to decrease the prevalence and emergence of Antimicrobial Resistance.

METHODS

A systematic review was undertaken to critically appraise and synthesise evidence for nurses', children's and parents' knowledge and understanding of antimicrobial stewardship, and of infection prevention and control in acute paediatric care settings. The Preferred Reporting Items for Systematic reviews and Meta-Analyses guided the review. Studies were included if they examined the factors that contributed to nurses' adherence to, or consumers' practice in relation to, antimicrobial stewardship and infection prevention and control.

RESULTS

Of the 16,957 papers identified, 50 studies conducted in acute paediatric settings met the eligibility criteria, and were included. Most studies were of low methodological quality. Fourteen studies evaluated nurses' knowledge and self-reported adherence to Infection Prevention and Control principles and identified consistent practice gaps by nurses. Six studies evaluating the effectiveness of education programs reported modest improvements in nurses' knowledge and adherence to infection prevention and control. There were 15 studies, that investigated consumers' involvement in infection prevention and control that identified the following themes: Consumer knowledge and attitudes to infection prevention and control and transmission-based precautions, and parents' willingness to take an active role in infection prevention. Six studies focused on paediatric nurses' role in antimicrobial stewardship, exploring the following themes: (1) nurses' understanding and beliefs of antimicrobial stewardship roles, and (2) barriers to nurses taking a greater role in antimicrobial stewardship. Nine studies explored the role of consumers in antimicrobial stewardship and identified consumers' misconceptions about the benefits and downplayed concerns regarding antibiotic use.

DISCUSSION

Although consumers articulated a willingness to be actively involved in infection prevention, observed practice remained lower than that required to consistently prevent infection transmission.

CONCLUSION

These findings highlight a critically important gap in current practice. In relation to optimal use of antimicrobials, although paediatric nurses were involved in supporting antimicrobial stewardship processes and educating consumers, they identified limited antimicrobial stewardship knowledge. Consumers appeared to lack understanding about the benefits of antibiotics and negated concerns regarding antibiotic use.

Incidence of health care-associated extended-spectrum β-lactamase-positive patients before and after discontinuation of contact precautions

BACKGROUND

Isolation of patients with multidrug-resistant organisms has been recommended in several guidelines. Recent evidence has suggested potential negative effects of isolation on patient well-being and facility throughput. Published literature shows a difference in transmission risk of extended-spectrum β-lactamase (ESBL)-producing organisms, suggesting that contact precautions may not be necessary for all ESBL-positive organisms.

METHODS

Incidence rates of health care-associated ESBL organisms were measured before and after eliminating the use of contact precautions for patients with only ESBL-positive organisms. The National Healthcare Safety Network surveillance methodology was used to measure incidence. Surgical site infections and carbapenem-resistant Enterobacteriaceae were excluded from the surveillance incidence.

RESULTS

The incidence of health care-associated ESBL infections from January 2014 through November 2015 was 3.71 per 10,000 patient days. The incidence from December 2015 through August 2017 was 3.00 per 10,000 patient days. This rate change was statistically significant (P = .022) CONCLUSIONS: This study found that discontinuing the use of contact precautions for patients colonized or infected with ESBL-positive organisms did not lead to an increased rate of health care-associated ESBL-positive infections or colonization.

A review of isolation practices and procedures in healthcare settings

The notion of 'isolation' in infectious diseases refers to the possibility of people known or suspected to be infected from the wider population, and has historically been used to control and prevent the spread of infectious diseases. Isolation practices in healthcare settings evolved over the 20th century resulting in a focus on the disruption of known routes of potential transmission. There was renewed attention to infection prevention and control (IPC) in the UK at the turn of the 20th century after high-profile reports acknowledged the importance of IPC as a key indicator of high-quality clinical care, and the impact of healthcare-acquired infections. There has been a shift away from isolation wards towards isolation in single rooms on general wards. For infections that are spread by the airborne, droplet or contact routes, placing the patient in single-room isolation is considered to be an important component of transmission-based precautions (TBPs). However, in practice isolation is complex and a number of challenges are involved in implementing IPC procedures.

Improving healthcare worker adherence to the use of transmission-based precautions through application of human factors design: a prospective multi-centre study

A key component of transmission-based precautions (TBPs) is the use of personal protective equipment (PPE) but healthcare worker (HCW) adherence remains suboptimal. A human factors-based intervention was implemented to improve adherence to TBPs including (i) improved signage, (ii) standardized placement of signage, (iii) introduction of a mask with integrated face shield, and (iv) improvement in PPE availability. Donning of the correct PPE by HCWs improved significantly (79.7 vs 56.4%; P < 0.001). This approach may be more effective than education alone, but further study is required to determine sustainability and subsequent impact on transmission of healthcare-associated infections.

Nursing students' knowledge, attitude and practices of infection prevention and control guidelines at a tertiary institution in the Western Cape: A cross sectional study

BACKGROUND

Nurses in sub-Saharan Africa are particularly at a higher risk of acquiring nosocomial infections, considering the increased prevalence of infectious diseases. It is therefore imperative that these nurses have a sound knowledge and understanding of infection prevention procedures.

OBJECTIVE

The main objective of this study was to describe the knowledge, attitudes and practices concerning infection prevention and control precautions among nursing students in a resource limited setting.

METHOD

A cross sectional study design was employed. A self-administered questionnaire concerning infection prevention and control guidelines were made available to students enrolled in a mainstream programme for completion of an undergraduate nursing degree.

SETTING AND PARTICIPANTS

A total of 301 students at second, third and final years of study from a tertiary institution in the Western Cape were invited to participate.

RESULTS

The final cohort comprised of 301 students with the majority between the ages of 17-26 (88.2%), with a mean age of 23 ± 4.7 (SD) years and the dominant gender being female (83.4%). According to the classification system used in this study, the majority of the students were overall evaluated as having good level of knowledge (47.4%) and poor attitude (41.7%) scores, with little difference in practice scores observed between different years of study. There was a positive correlation found between students' total attitude and total practice scores (r = 0.48 p < 0.01). Results showed that significant associations between gender and knowledge (p < 0.05), attitudes (p < 0.05) and practice (p < 0.05) exists. There was also a significant association between province and those who repeated a year with total knowledge scores (p < 0.05).

CONCLUSION

Based on the results of this study, it is recommended that interactive infection control courses that promote critical thinking are implemented at undergraduate level along with more stringent forms of assessments focusing on infection prevention and control, during clinical training.

Degowning the controversies of contact precautions for methicillin-resistant Staphylococcus aureus: A review

BACKGROUND

Contact precautions (CPs) are recommended to prevent methicillin-resistant Staphylococcus aureus (MRSA) transmission in institutions. Rising doubts about CP effectiveness and recognition of unintended consequences for patients have raised questions about the benefit. The objective of this study was to evaluate the effectiveness and adverse outcomes associated with CPs for prevention of MRSA transmission.

METHODS

We searched PubMed, Embase, and the Cochrane Library for articles related to effectiveness and adverse outcomes of CPs in patients with MRSA. Criteria for inclusion included the following: articles conducted in the United States, articles performed in an acute care setting, articles that were not a case series or review, and those with standardized collection of data or inclusion of case and control groups. Results were summarized and examined for potential limitations. Recommendations were based on our findings.

RESULTS

CPs reduced MRSA transmission in epidemic settings and in instances with high compliance, but a decrease in infection rates was not shown. Unintended consequences of CPs include decreased health care provider (HCP) time spent with patients, low HCP compliance, decreased perceptions of comfort from patients, and greater likelihood of patient complaints and negative psychologic implications.

CONCLUSION

In endemic settings, there are few data to support routine use of CPs to control the spread of MRSA. Education should be performed in hospitals to improve patients' perception of care and understanding of CPs when implemented and HCPs' adherence to good hand hygiene and standard precautions practices.

Utilization of paediatric isolation facilities in a TB-endemic setting

Introduction

In hospital settings, patient isolation is used to limit transmission of certain pathogens (e.g. M. tuberculosis [TB], antibiotic-resistant bacteria and viruses causing respiratory and enteric infection). Data is lacking on utilization of paediatric isolation facilities in low-resource, TB-endemic settings.

Methods

Prospective weekday observation of 18 paediatric isolation rooms at Tygerberg Children’s Hospital, Cape Town, South Africa, was conducted between 1 May 2014 and 31 October 2014 documenting: occupancy rate; indication for isolation; duration of isolation; application of transmission-based precautions and infection prevention (IPC) behaviour of personnel. Potential under-utilization of isolation rooms was determined by cross-referencing isolation room occupancy with laboratory isolates of antibiotic-resistant bacteria, M. tuberculosis and selected viral pathogens.

Results

Six percent (335/5906) of hospitalized children were isolated: 78 % (260/335) for IPC purposes. Most IPC-isolated patients had community-acquired infections (213/260; 82 %), including tuberculosis (130/260; 50 %) and suspected viral infections (75/260; 29 %). Children (median age 17 months [IQR 6–50]) spent 4 days (IQR 2–8) in isolation. Isolation occupancy was 66 % (2172/3294 occupied bed days), but varied significantly by month. Laboratory data identified an additional 135 patients warranting isolation with 2054 extra bed-days required. Forty patients with 171 patient days of inappropriate isolation were identified. During 1223 weekday visits to IPC-isolated patient rooms: alcohol-based handrub was available (89 %); transmission-based precautions were appropriately implemented (71 %); and personal protective equipment was provided (74 %). Of 358 observed interactions between paediatric staff and isolated patients, hand hygiene compliance was 65 % and adherence to transmission-based precautions was 58 %.

Conclusion

Patients isolated for TB (under airborne precautions) accounted for more than half of all isolation episodes. Missed opportunities for patient isolation were common but could be reduced by implementation of syndromic isolation. Demand for isolation facilities was seasonal, with projected demand exceeding available isolation beds over winter months.

Healthcare workers' decision-making about transmission-based infection control precautions is improved by a guidance summary card

BACKGROUND

Transmission-based precautions (TBPs) are infection control measures designed to interrupt pathogen transmission. Success relies on early recognition of patients with potentially infectious syndromes, then the implementation of appropriate TBPs. We are aware of no literature evaluating interventions to facilitate healthcare workers (HCWs) in implementing TBPs.

AIM

To evaluate the impact of a TBP guidance summary card on HCWs' decision-making about the appropriate implementation of TBPs.

METHODS

A prospective audit was carried out to assess HCWs' ability to make decisions about TBP implementation. Following the first audit phase, staff were issued with a guidance card summarizing local TBP guidelines, identifying and addressing relevant TBP measures for infectious syndromes and specific organisms. The audit cycle was then completed to assess the impact of this intervention.

FINDINGS

Baseline knowledge of appropriate TBP measures was low. Provision of a TBP summary card was significantly associated with the ability of staff carrying the card to correctly decide what TBPs are required in a variety of clinical situations, including Clostridium difficile infection [N = 107; odds ratio (OR): 27.0; 95% confidence interval (CI): 8.37-86.8; P < 0.0001], norovirus diarrhoea and vomiting (N = 107; OR: 94.3, 95% CI: 25.0-356; P < 0.0001), influenza-like illness (N = 107; OR: 85.2; 95% CI: 4.94-1470; P < 0.0001) and the difference between surgical and FFP3 masks (N = 107; OR: 412; 95% CI: 23.4-7246; P < 0.0001).

CONCLUSION

There is a lack of knowledge about TBP among HCWs. This study demonstrates how an inexpensive TBP summary card is an effective mechanism for improving (i) point-of-care access to TBP guidance and (ii) decision-making about appropriate implementation of TBP.

Respiratory protection policies and practices among the health care workforce exposed to influenza in New York State: evaluating emergency preparedness for the next pandemic

BACKGROUND

New York State hospitals are required to implement a respiratory protection program (RPP) consistent with the Occupational Safety and Health Administration respirator standard. Guidance provided during the 2009 novel H1N1 pandemic expanded on earlier recommendations, emphasizing the need to keep staff in all health care settings healthy to maintain services.

METHODS

New York State hospitals with emergency departments having more than 1,000 visits annually were invited to participate; 23 hospitals participated. Health care workers, unit managers, and hospital managers were interviewed regarding knowledge, beliefs, and practices of respiratory protection. Interviewees were observed donning and doffing an N-95 respirator as they normally would during patient care. Written RPPs for each hospital were evaluated.

RESULTS

The majority of the hospitals surveyed had implemented an RPP, although unawareness of the policies and practices, as well as inadequacies in education and training exist among health care workers.

CONCLUSION

Health care workers and other hospital employees may be unnecessarily exposed to airborne infectious diseases. Having an RPP ensures safe and effective use of N-95 respirators and will help prevent avoidable exposure to disease during a pandemic, protecting the health care workforce and patients alike.

"Recognizing rapport": health professionals' lived experience of caring for patients under transmission-based precautions in an Australian health care setting

BACKGROUND

Preventing health care-associated infections is essential to the safety and quality of health care. Although patients' experience of care under isolation is well established, little is known of health care workers' experiences when providing such care. This study explored the health professionals; lived experience of caring for patients under transmission-based precautions.

METHODS

Interpretive phenomenology was used to examine 12 health care professionals' lived experience of providing care under transmission-based precautions in 3 health care facilities in Australia. Data were obtained from in-depth interviews and observations of health professionals.

FINDINGS

The essential phenomena of "recognizing rapport" represented the health professionals' lived experience. Three themes emerged starting with (1) relationships with others, their rapport and communication with patients, patients' families and visitors, and colleagues. These relationships are influenced by (2) barriers to practice, such as personal level of comfort when wearing personal protective equipment, physical limitations of the environment, and management of workload and resources. Such barriers influence (3) patient outcomes, namely the quality of the care provided and adverse events.

CONCLUSION

In the context of caring for patients under transmission-based precautions, the relationships between health professionals and their patients are critical to the quality and safety of health care with respect to infection prevention and control.
