Risk of infection following a visit to the emergency department: a cohort study

Associations between frailty, depression and risk of hospitalisation for infection: A large prospective cohort study

BACKGROUND

There is a considerable lack of epidemiological evidence on whether frailty, and frailty comorbid depression could increase the risk of infections in older adults. This study aimed to examine the prospective association between frailty, depression, and risk of infections.

METHODS

A total of 308,892 eligible participants were included. Linked hospital admission records (HES) were used to identify a primary or secondary diagnosis of depression, and infection. Frailty was assessed by Fried frailty phenotype indicators. Cox proportional hazard model was conducted to examine the associated risk between frailty, depression, comorbid frailty and depression and risk of incident infections. Results were stratified by age and gender.

RESULTS

During the follow-up, 74,749 (24.19 %) incident any infection cases were identified, the incidence density of any infection was 17.29/1000 person years. Frailty alone (HR = 1.38, 95 % CI: 1.33-1.43), depression alone (HR = 1.90, 95 % CI: 1.86-1.94), and comorbid frailty and depression (HR = 1.91, 95 % CI: 1.82-1.99) were associated with greater risks of any infections relative to participants with neither frailty nor depression. The associations between frailty alone, depression alone, comorbid frailty and depression, and any infections/most infection subtypes were significant for all age strata in both male and female.

LIMITATIONS

Frailty phenotype was assessed through the adapted Fried criteria, based on a mix of self-reported and objective measurements.

CONCLUSION

Frailty, depression, and comorbid frailty and depression were significantly associated with increased risk of incident infections.

Hand hygiene in emergencies: Multiprofessional perceptions from a mixed methods based online survey in Germany

Introduction

Despite high vulnerability to infection, hand disinfection compliance in emergencies is low. This is regularly justified as the disinfection procedure delays life support, and instead, wearing disposable gloves is preferred. Simulation studies showed higher achievable compliance than detected in real-life situations. This study aimed to explore healthcare providers' attitudes toward hand disinfection and using gloves in emergencies.

Methods

We conducted an anonymous online survey in Germany on the attitude and subjective behavior in the five moments of hand hygiene in a closed environment and an open convenience sampling survey. Statistics included paired student's t-tests corrected for multiple testing. For qualitative analysis, we employed a single-coder approach.

Results

In 400 participants, we detected low priority of WHO-1 (before touching a patient) and WHO-2 (before clean/aseptic procedure) hand hygiene moments, despite knowing the risks of omission of hand disinfection. For all moments, self-assessment exceeded the assessment of colleagues (p < 0.001). For WHO-3, we detected a lower disinfection priority for wearing gloves compared to contaminated bare hands. Qualitative analyses revealed five themes: basic conditions, didactic implementations, cognitive load, and uncertainty about feasibility and efficacy.

Discussion

Considering bias, the study's subjective nature, the unknown role of emergency-related infections contributing to hospital-acquired infections, and different experiences of healthcare providers, we conclude that hand disinfection before emergencies is de-prioritized and justified by the emergency situation regardless of the objective feasibility.

Conclusion

This study reveals subjective and objective barriers to implementation of WHO-1 and WHO-2 moments of hand disinfection to be further evaluated and addressed in educational programs.

Missed nursing care in emergency departments: a cross-sectional descriptive study

BACKGROUND

Missed care refers to the omission or delay in performing any aspect of patient's care (either a part of the care or the entire care). Currently, missed care has become a growing concern at the international level, which threatens the quality and safety of care and cases many unwanted consequences. This study aims to investigate the frequency and types of missed nursing care in the emergency departments of selected hospitals affiliated to Tehran University of Medical Sciences.

METHODS

This is a cross-sectional and descriptive- observational study that was conducted with the aim of determining the frequency and types of missed nursing care in the emergency departments of selected hospitals affiliated to Tehran University of Medical Sciences from January 2020 to June 2020. The research community included all nursing care offered in the designated areas, as well as all nurses working in the emergency departments of selected hospitals. Finally, 146 nurses were selected by census method. The information was collected by self-reporting method and the researcher's observation. Demographic information questionnaire, a researcher-made checklist were used to determine the frequency and types of missed nursing care. 384 observations were made for each item. Descriptive statistics methods were used to analyze the data.

RESULTS

The area of checking equipment and emergency trolley(mean = 81.80) had the lowest and the area of patient communication(mean = 55.72) had the highest level of missed care.

CONCLUSIONS

The level of missed nursing care in the emergency departments of selected hospitals affiliated to Tehran University of Medical Sciences was found to be high and the highest amount was related to the field of communication with the patient. Therefore, it is recommended that the details of missed nursing care in each area should be considered by nursing managers.

The Utilization of e-Health in Lymphedema Care: A Narrative Review

Background: Electronic health (e-Health), refers to technologies that can be utilized to enhance patient care as well as collect and share health information. e-Health comprises several umbrella terms, including telehealth, mobile health, e-Health, wearables, and artificial intelligence. The types of e-Health technologies being utilized in lymphedema (LE) care are unknown. Method: In this narrative review, a search of published research on the utilization of e-Health technologies in LE-related care was conducted. Results: Five different types of e-Health modalities were found (robotics, artificial intelligence, electronic medical records, smart wearable devices, and instructive online information) spanning 14 use cases and 4 phases of care (preventative, diagnostic, assessment, and treatment phases). Broad e-Health utilization examples were found including robotic-assisted surgery to reduce the likelihood of LE after lymphadenectomy, machine learning to predict patients at risk of filarial-related LE, and a novel wearable device prototype designed to provide lymphatic drainage. Conclusions: e-Health has reported merit in the prevention, diagnoses, assessment, and treatment of LE with utilization demonstrating cutting edge applicability of e-Health for achieving optimal patient care and outcomes. As technology continues to advance, additional research into the utilization of e-Health in LE care is warranted.

A novel opportunity to improve heart failure care: focusing on subcutaneous furosemide

The prevalence of heart failure (HF) continues to rise in developed nations. Symptomatic congestion is the most common reason for patients to seek medical attention, and management often requires intravenous (IV) diuretic administration in the hospital setting. Typically, the number of admissions increases as the disease progresses, not only impacting patient survival and quality of life but also driving up healthcare expenditures. pH-neutral furosemide delivered subcutaneously using a proprietary, single-use infusor system (Furoscix) has a tremendous potential to transition in-hospital decongestive therapy to the outpatient setting or to the patient's home. This review is aimed at providing an overview of the pharmacodynamic and pharmacokinetic profile of the novel pH-neutral furosemide in addition to the most recent clinical trials demonstrating its benefit when used in the home setting. Given the newest data and approval by the Food and Drug Administration in the US, it has the potential to revolutionize the care of patients with decompensated HF. Undoubtedly, it will lead to improved quality of life as well as significantly reduced healthcare costs related to hospital admissions.

The hospital care and outcomes of long-term care patients treated by paramedics during an emergency call: exploring the potential impact of 'treat-and-refer' pathways and community paramedicine

INTRODUCTION

Adults living in long-term care (LTC) are at increased risk of harm when transferred to the emergency department (ED), and programs targeting treatment on-site are increasing. We examined characteristics, clinical course, and disposition of LTC patients transported to the ED to examine the potential impact of alternative models of paramedic care for LTC patients.

METHODS

We conducted a health records review of paramedic and ED records between April 1, 2016, and March 31, 2017. We included emergency calls originating from LTC centers and patients transported to either ED campus of The Ottawa Hospital. We excluded scheduled or deferrable transfers, and patients with Canadian Triage and Acuity Scale of 1. We categorized patients into groups based on care they received in the ED. We calculated standardized differences to examine differences between groups.

RESULTS

We identified four groups: (1) patients requiring no treatment or diagnostics in the ED (7.9%); (2) patients receiving ED treatment within current paramedic directives and no diagnostics (3.2%); (3) patients requiring diagnostics or ED care outside current paramedic directives (54.9%); and (4) patients requiring admission (34.1%).

CONCLUSION

This study found 7.9% of LTC patients transported to the ED did not receive diagnostics, medications, or treatment, and overall 11.1% of patients could have been treated by paramedics within current medical directives using 'treat-and-refer' pathways. This group could potentially expand utilizing community paramedics with expanded scopes of practice.

Improving Communication in Nursing Homes Using Plan-Do-Study-Act Cycles of an SBAR Training Program

BACKGROUND

Incomplete communication between staff and providers may cause adverse outcomes for nursing home residents. The Situation-Background-Assessment-Recommendation (SBAR) tool is designed to improve communication around changes in condition (CIC). An adapted SBAR was developed for the Centers for Medicare and Medicaid Services demonstration project, OPTIMISTIC, to increase its use during a resident CIC and to improve documentation.

METHODS

Four Plan-Do-Study-Act (PDSA) cycles to develop and refine successive protocol implementation of the OPTIMISTIC SBAR were deployed in four Indiana nursing homes. Use of SBAR, documentation quality, and participant surveys were assessed pre- and post-intervention implementation.

RESULTS

OPTIMISTIC SBAR use and documentation quality improved in three of the four buildings. Participants reported improved collaboration between nurses and providers after SBAR intervention.

CONCLUSION

Successive PDSA cycles implementing changes in an OPTIMISTIC SBAR protocol for resident CIC led to an increase in SBAR use, improved documentation, and better collaboration between nursing staff and providers.

The cost-effectiveness of a nursing home-based transitional care unit for increasing the potential for independent living in the community among hospitalized older adults

OBJECTIVE

In Canada, a persistent barrier to achieving healthcare system efficiency has been patient days accumulated by individuals with an alternate level of care (ALC) designation. Transitional care units (TCUs) may address the capacity pressures associated with ALC. We sought to assess the cost-effectiveness of a nursing home (NH) based TCU leveraging existing infrastructure to support a hospitalized older adult's transition to independent living at home.

METHODS

This case-control study included frail, older adults who received care within a function-focused TCU following a hospitalization between 1 March 2018 and 30 June 2019. TCU patients were propensity score matched to hospitalized ALC patients ("usual care"). The primary outcome was days without requiring institutional care six months following discharge, defined as institutional-free days. This was calculated by excluding all days in hospitals, rehabilitation facilities, complex continuing care facilities and NHs. Using the total direct cost of care up to discharge from TCU or hospital, the incremental cost-effectiveness ratio was calculated.

RESULTS

TCU patients spent, on average, 162.0 days institution-free (95% CI: 156.3-167.6d) within six months days post-discharge, while usual care patients spent 140.6 days institution-free (95% CI: 132.3-148.8d). TCU recipients had a lower total cost of care, by CAN$1,106 (95% CI: $-6,129-$10,319), due to the reduced hospital length of stay (mean [SD] 15.6d [13.3d] for TCU patients and 28.6d [67.4d] days for usual care). TCU was deemed the more cost-effective model of care.

LIMITATIONS

The main limitation was the potential inclusion of patients not eligible for SAFE in our usual group. To minimize this selection bias, we expanded the geographical pool of ALC patients to patients with SAFE admission potential in other area hospitals.

CONCLUSIONS

Through rehabilitative and restorative care, TCUs can reduce hospital length of stay, increase potential for independent living, and reduce risk for subsequent institutionalization.

Sustaining telecare consultations in nurse-led clinics: Perceptions of stroke patients and advanced practice nurses: A qualitative study

Objective

The ongoing pandemic has accentuated the use of telecare services; however, only limited progress has been made in understanding the barriers and facilitators to using these services. In order to move towards sustaining such essential services, the present study aimed to ascertain the experiences of stroke survivors and healthcare providers regarding the utilization of a post-stroke telecare service in Hong Kong.

Methods

Interpretive description was employed for this study. Semi-structured discussions and interviews were undertaken with nine stroke survivors and four stroke nurses who delivered the telecare services. The principles of thematic analysis were inductively followed to analyse the data. The Standards for Reporting Qualitative Research checklist was used to guide the reporting of the data.

Results

Three themes emerged: (a) pre-existing post-discharge service pathways; (b) push factors/facilitators for telecare usage; and (c) barriers to telecare usage. Overall, the telecare service was considered a significant alternative and one that complements conventional face-to-face follow-ups. Stroke survivors were motivated to use the service because it was convenient and flexible. However, significant barriers exist, including technical issues and a lack of guidelines and training opportunities for healthcare providers.

Conclusions

Although telecare is still evolving, several factors drive stroke survivors to use the service. Attention needs to be paid to the emerging barriers to improve long-term usage of the service. Clear guidelines are needed to underpin the development and implementation of telecare services.

Improving In-Hospital Care For Older Adults: A Mixed Methods Study Protocol to Evaluate a System-Wide Sub-Acute Care Intervention in Canada

Introduction:

Acute care hospitals often inadequately prepare older adults to transition back to the community. Interventions that seek to improve this transition process are usually evaluated using healthcare use outcomes (e.g., hospital re-visit rates) only, and do not gather provider and patient perspectives about strategies to better integrate care. This protocol describes how we will use complementary research approaches to evaluate an in-hospital sub-acute care (SAC) intervention, designed to better prepare and transition older adults home.

Methods:

In three sequential research phases, we will assess (1) SAC transition pathways and effectiveness using administrative data, (2) provider fidelity to SAC core practices using chart audits, and (3) SAC implementation outcomes (e.g., facilitators and barriers to success, strategies to better integrate care) using provider and patient interviews.

Results:

Findings from each phase will be combined to determine SAC effectiveness and efficiency; to assess intervention components and implementation processes that ‘work’ or require modification; and to identify provider and patient suggestions for improving care integration, both while patients are hospitalized and to some extent after they transition back home.

Discussion:

This protocol helps to establish a blueprint for comprehensively evaluating interventions conducted in complex care settings using complementary research approaches and data sources.

Conclusions

I'm here because I was told to come: a study of cancer patients' reasons for attending the emergency department

OBJECTIVES

Patients with cancer are seen frequently in emergency departments (EDs). It has been proposed that many of these visits are preventable, but the patient perspective has not been well-studied.

METHODS

We conducted structured interviews with a convenience sample of patients who presented to a single ED with a cancer-related complaint. We asked standardized questions regarding patient predisposing characteristics, enabling factors (e.g., access to support), and perceived need for care. We compared the reported perceived need with the evaluated need by ED healthcare providers. Themes were identified using descriptive content analysis.

RESULTS

Forty-five patients completed interviews, of whom 30 (67%) were admitted to hospital. The most frequent reasons for seeking ED care were pain (includes abdominal) (33%), fever (11%), and weakness (11%). The majority (77%) did not make the decision to go to the ED alone: healthcare providers (40%, most commonly oncologists) and caregivers (36%) were the reported decision-makers in these cases. The majority (73%) felt their ED visit was not preventable. Themes of an alternative oncological setting for tests, improved community services, and both earlier medication management and referral to specialist care were identified from patients who reported their visit was avoidable. Congruence between (patient) perceived need and evaluated need was high (96%).

CONCLUSIONS

The minority of patients made the decision to seek ED care by themselves. While the majority did not believe emergency care was avoidable, those who did had cogent suggestions to that end. Patient's assessments of their own need had high agreement with ED providers' evaluations.

Managing adult patients with infectious diseases in emergency departments: international ID-IRI study

We aimed to explore factors for optimizing antimicrobial treatment in emergency departments. A single-day point prevalence survey was conducted on January 18, 2020, in 53 referral/tertiary hospitals in 22 countries. 1957 (17%) of 11557 patients presenting to EDs had infections. The mean qSOFA score was 0.37 ± 0.74. Sepsis (qSOFA ≥ 2) was recorded in 218 (11.1%) patients. The mean qSOFA score was significantly higher in low-middle (1.48 ± 0.963) compared to upper-middle (0.17 ± 0.482) and high-income (0.36 ± 0.714) countries (P < 0.001). Eight (3.7%) patients with sepsis were treated as outpatients. The most common diagnoses were upper-respiratory (n = 877, 43.3%), lower-respiratory (n = 316, 16.1%), and lower-urinary (n = 201, 10.3%) infections. 1085 (55.4%) patients received antibiotics. The most-commonly used antibiotics were beta-lactam (BL) and BL inhibitors (n = 307, 15.7%), third-generation cephalosporins (n = 251, 12.8%), and quinolones (n = 204, 10.5%). Irrational antibiotic use and inappropriate hospitalization decisions seemed possible. Patients were more septic in countries with limited resources. Hence, a better organizational scheme is required.

Development and Application of a Surveillance Method for Healthcare-Associated Infections in Long-Term Care Hospitals in Korea

Background

This study developed a surveillance method for healthcare-associated infections (HAIs) in long-term care hospitals (LTCHs) and investigated the current status of HAIs in LTCHs in Korea.

Methods

We applied the HAI-related surveillance criteria for long-term care facilities developed by McGeer in six LTCHs.

Results

The 197 confirmed HAIs corresponded to incidence rates of 30.38/100 inpatients and 1.57/1,000 days of hospitalization and included 84 cases of respiratory tract infection (43.8%), 78 cases of systemic infection (40.6%), 24 cases of gastrointestinal tract infection (12.5%), and 6 cases of skin and soft tissue mucosal infection (2.1%). The subtypes included 78 cases of unexplained febrile illness (40.6%); 40 cases of pneumonia (20.8%); 27 cases of lower respiratory tract infection (14.1%); 21 cases of gastroenteritis (10.9%); 9 cases of influenza-like illness (4.7%); 8 cases of common cold or pharyngitis (4.2%); 4 cases of cellulitis, soft tissue, or wound infection (2.1%); 3 cases of Clostridium difficile infection (1.6%); 1 case of conjunctivitis (0.5%); and 1 case of fungal oral/perioral and skin infection (0.5%).

Conclusion

Establishing an HAI surveillance method for LTCHs and identifying HAI rates and risk factors among LTCH patients may help prevent HAIs in LTCHs in Korea.

Characteristics of frequent paediatric users of emergency departments in England: an observational study using routine national data

BACKGROUND

Frequent attendances of the same users in emergency departments (ED) can intensify workload pressures and are common among children, yet little is known about the characteristics of paediatric frequent users in EDs.

AIM

To describe the volume of frequent paediatric attendance in England and the demographics of frequent paediatric ED users in English hospitals.

METHOD

We analysed the Hospital Episode Statistics dataset for April 2014-March 2017. The study included 2 308 816 children under 16 years old who attended an ED at least once. Children who attended four times or more in 2015/2016 were classified as frequent users. The preceding and subsequent years were used to capture attendances bordering with the current year. We used a mixed effects logistic regression with a random intercept to predict the odds of being a frequent user in children from different sociodemographic groups.

RESULTS

One in 11 children (9.1%) who attended an ED attended four times or more in a year. Infants had a greater likelihood of being a frequent attender (OR 3.24, 95% CI 3.19 to 3.30 vs 5 to 9 years old). Children from more deprived areas had a greater likelihood of being a frequent attender (OR 1.57, 95% CI 1.54 to 1.59 vs least deprived). Boys had a slightly greater likelihood than girls (OR 1.05, 95% CI 1.04 to 1.06). Children of Asian and mixed ethnic groups were more likely to be frequent users than those from white ethnic groups, while children from black and 'other' had a lower likelihood (OR 1.03, 95% CI 1.01 to 1.05; OR 1.04, 95% CI 1.01 to 1.06; OR 0.88, 95% CI 0.86 to 0.90; OR 0.90, 95% CI 0.87 to 0.92, respectively).

CONCLUSION

One in 11 children was a frequent attender. Interventions for reducing paediatric frequent attendance need to target infants and families living in deprived areas.

Effect of Access to After-Hours Primary Care on the Association Between Home Nursing Visits and Same-Day Emergency Department Use

PURPOSE

Previous work has demonstrated that home care patients have an increased risk of visiting the emergency department after a home nursing visit on the same day. We investigated whether this association is modified by greater access to after-hours primary care.

METHODS

We conducted a population-based case-crossover study of home care patients in Ontario, Canada in 2014-2016. Emergency department visits after 5:00 pm were selected as case periods and matched, within the same patient, to control periods within the previous week. The association between home nursing visits and same-day emergency department visits was estimated with conditional logistic regression. Access to after-hours primary care, measured on the patient and practice level, was tested for effect modification using an interaction term approach. Analysis was performed separately for all emergency department visits and a less urgent subset not admitted to hospital.

RESULTS

A total of 11,840 patients contributed cases to the analysis. Patients with a history of after-hours primary care use had a smaller increased risk of a same-day after-hours emergency department visit (OR = 1.18; 95% CI, 1.06-1.30) compared with patients with no after-hours care (OR = 1.31; 95% CI, 1.25-1.39). The modifying effect was stronger among emergency department visits not admitted to hospital (OR = 1.11; 95% CI, 0.97-1.28 vs OR = 1.41; 95% CI, 1.31-1.51).

CONCLUSION

Greater access to after-hours primary care reduced the risk of less-urgent emergency department use associated with home nursing visits. These findings suggest increasing access to after-hours primary care could prevent some less-urgent emergency department visits.

Direct in-hospital admission via ambulance (DIVA): A retrospective observational study

BACKGROUND

Prolonged stays in emergency departments increase the risk of adverse events in elderly patients. To optimize care for nonurgent patients who need in-hospital admission, a patient-focused improvement project named Direct In-hospital admission Via Ambulance (DIVA) was launched at Örebro University Hospital.

PURPOSE

This study describes the effects of DIVA. The primary outcome was time to in-hospital admission. Secondary outcomes were the in-hospital admission rate, the in-hospital length of stay and patient characteristics.

METHOD

This was a retrospective observational study. Descriptive and comparative statistics were used. All patients identified by the ambulance nurse as nonurgent but with an apparent need for in-hospital admission were candidates for direct in-hospital admission. The results were compared with those of a reference group.

RESULT

In total, 127 patients were included, with 45 patients in the DIVA group and 82 patients in the reference group. In the DIVA group, 24 patients were directly admitted. The median time to in-hospital admisson was 49.5 min for direct admitted patients and 278.5 min for the reference group. There was a statistical significant difference between the groups (p < 0.01).

CONCLUSION

The current study indicates that time to in-hospital admission could be reduced by DIVA.

PACE-IT study protocol: a stepped wedge cluster randomised controlled trial evaluating the implementation of telehealth visual assessment in emergency care for people living in residential aged-care facilities

Background

Transfer of residential aged-care facility (RACF) residents to Emergency Departments (ED) is common, risky and expensive. RACF residents who present to ED are more likely to have hospital readmissions, longer stays and face major risks related to hospital acquired complications. Aged Care Emergency services (ACE) is a nurse led, protocol- guided, telephone RACF/ED outreach model that has been shown to be effective in reducing hospitalisation and length of hospital stay for RACF residents in the Hunter New England Local Health District, New South Wales (NSW). The Partnerships in Aged-Care Emergency services using Interactive Telehealth (PACE-IT) project enhances ACE by incorporating interactive video assessment and consultation. The PACE-IT project’s primary aim is to assess whether augmentation of ACE services through the addition of protocol-guided interactive Visual Telehealth Consultation (VTC) for clinical decision-making, plus telephone follow-up, reduces RACF resident transfers to ED.

Methods

A stepped-wedge cluster randomised controlled trial will be conducted. The intervention will be delivered sequentially to 8 clusters; each cluster comprises one ED and two RACFs in NSW, Australia.

The 16 RACFs in the study will be selected for order of implementation using a computer-generated randomisation sequence. A 2-step randomisation process will be undertaken, randomising the hospital EDs first and then randomising the RACFs aligned with each hospital.

The PACE-IT intervention comprises: an initial phone call by RACFs to the ACE service in the ED; the ACE service in ED responds with a protocol-guided VTC, a management plan agreed between all participants; an automated consultation summary letter to the General Practitioner and the RACF; a post VTC 24 h follow-up phone call to the RACF.

Discussion

If shown to be effective, the intervention has the potential to improve the clinical care and quality of life for residents. Findings will provide high level evidence that will inform sustainable change and broad translation into practice across NSW. It will show how the change has been achieved and highlight success factors for scalability and sustainability. It will inform review of processes, the development of policy and guidelines that will integrate PACE-IT into existing service models in NSW.

Trial registration

The trial is registered with the Australian New Zealand Clinical Trials Registry (Trial ID ACTR N12619001692123) 02/12/2020.)

The Safety and Effectiveness of On-Site Paramedic and Allied Health Treatment Interventions Targeting the Reduction of Emergency Department Visits by Long-Term Care Patients: Systematic Review

INTRODUCTION

Programs that seek to avoid emergency department (ED) visits from patients residing in long-term care facilities are increasing. We sought to identify existing programs where allied healthcare personnel are the primary providers of the intervention and, to evaluate their effectiveness and safety.

METHODS

We systematically searched Medline, CINAHL and EMBASE with terms relating to long-term care, emergency services, hospitalization and allied health personnel. We reviewed 11,176 abstracts and included 22 studies in our narrative synthesis, which we grouped by intervention category.

RESULTS

We found five categories of interventions including: 1) use of advanced practice nursing; 2) a program called Interventions to Reduce Acute Care Transfers (INTERACT); 3) end-of-life care; 4) condition specific interventions; and 5) use of extended care paramedics. Among studies measuring that outcome, 13/13 reported a decrease in ED visits, and 16/17 reported a decrease hospitalization in the intervention groups. Patient adverse events such as functional status and relapse were seldom reported (6/22) as were measures of emergency system function such as crowding/inability of paramedics to transfer care to the ED (1/22). Only 4/22 studies evaluated patient mortality and 3/4 found a non-statistically significant worsening.

CONCLUSION

We found five types of programs/interventions which all demonstrated a decrease in ED visits or hospitalization. However, most studies were observational and few assessed patient safety. Many identified programs focused on increased primary care for patients, and interventions addressing acute care issues, such as community paramedics, deserve more study.

Predictors of transport to hospital after emergency ambulance call-out for older people living in residential aged care

OBJECTIVES

People living in residential aged care (RAC) frequently experience ambulance call-out. These episodes may have unintended consequences, yet remain under-investigated. Our aim was to examine clinical and sociodemographic features associated with transfer to hospital for this population.

METHODS

Retrospective cohort study using 6 years of clinical data from Ambulance Victoria (AV). Data analysis included multilevel multivariable logistic regression analysis of factors associated with transport to hospital.

RESULTS

Odds of transfer were greater for people in rural areas, those with a history of depression, cardiovascular disease and osteoporosis, and residents prescribed antipsychotic and antidepressant medication. Ambulance call-out for trauma (commonly low-level fall) was less frequently transferred to hospital than that for a medical complaint.

CONCLUSION

These results will improve prediction of call-outs likely to require transfer. Findings include identification of clinical features to be targeted by community and preventative health programs to reduce risk of acute health deterioration and requirement for emergency hospital transfer.

Evaluating the impact of a mass gathering (2018 Commonwealth Games) on emergency department presentations with communicable diseases: A retrospective cohort study

OBJECTIVE

To identify the impact of a mass gathering event (MGE) on emergency department (ED) patient presentations with communicable diseases and underpinning syndromic indicators (SIs).

METHODS

This retrospective observational cohort study was undertaken in one large public teaching hospital ED in Queensland, Australia. Routinely collected ED data for patient presentations with an ICD-10 diagnosis corresponding to a communicable disease were used to compare demographic characteristics, clinical characteristics, and outcomes before (March 23 to April 3), during (April 4 to April 15), and after (April 16 to April 27) the 2018 Commonwealth Games.

RESULTS

Over the study period, there were 10 595 patient presentations to the ED; 14.2% (n = 1503) were diagnosed with a communicable disease. The median age of those with a communicable disease was 8 years, 50.5% (n = 759) were female, and 24.8% (n = 373) arrived by ambulance. The most common communicable disease profile was respiratory in nature (51.4%, n = 772). The most common SI was altered breathing (24.0%, n = 185). ED length of stay (LOS) increased over the study period (pre: 160 min; during: 163 min; post: 180 min, p < 0.001).

CONCLUSIONS

The 2018 Commonwealth Games had an impact on ED presentations with communicable diseases, in terms of LOS. A longer LOS and higher percentage of patients with a LOS of more than 4 hrs in the ED were noted following the MGE period. This outcome indicates a potential need to continue with up-scaled services. Future research is required to understand the broader impact on other EDs in the area, and longitudinal patient follow-up is needed to determine the potential spread of communicable diseases.

Prevalence and Risk Factors for Positive Nasal Methicillin-Resistant Staphylococcus aureus Carriage Among Orthopedic Patients in Korea

Methicillin-resistant Staphylococcus aureus (MRSA) causes purulent skin and soft tissue infections as well as other life-threatening diseases. Recent guidelines recommend screening for MRSA at the time of admission. However, few studies have been conducted to determine the prevalence and risk factors for MRSA colonization. A prospective data collection and retrospective analysis was performed. MRSA screening tests were performed using nasal swabs in patients enrolled between January 2017 and July 2018. Demographic data, socio-economic data, medical comorbidities, and other risk factors for MRSA carriage were evaluated among 1577 patients enrolled in the study. The prevalence of MRSA nasal carriage was 7.2%. Univariate regression analysis showed that colonization with MRSA at the time of hospital admission was significantly related to patient age, body mass index, smoking, alcohol, trauma, recent antibiotic use, and route of hospital admission. Multiple logistic regression analysis for the risk factors for positive MRSA nasal carriage showed that being under- or overweight, trauma diagnosis, antibiotic use one month prior to admission, and admission through an emergency department were related to MRSA colonization. This study highlights the importance of a preoperative screening test for patients scheduled to undergo surgery involving implant insertion, particularly those at risk for MRSA.

Interventions to improve hand hygiene compliance in emergency departments: a systematic review

The emergency department (ED) is where hand hygiene problems are significant as the procedures in the ED are often high risk and invasive. To date, there have been no comprehensive reviews on hand hygiene in EDs. The aim of this study was to investigate hand hygiene compliance (HHC) rate, factors affecting the HHC rate, and intervention strategies to improve HHC in EDs. Electronic databases were used to search for research published from 1948 to January 2018. The databases included ovidMEDLINE, ovidEMBASE, the Cochrane Library, CINAHL, Koreamed, and Kmbase. All study designs were included. Two reviewers independently extracted the data and assessed the bias risk using reliable and validated tools. A narrative synthesis was performed. Twenty-four studies, including 12 cross-sectional surveys and 12 interventional studies, were included. Of the 12 interventional studies reviewed, only 33% (N = 4) reported HHC rates of more than 50%. Factors that influenced HHC included types of healthcare worker, hand hygiene indication, ED crowding, positive attitudes towards HHC, patient location, auditing hand hygiene, and type of shift. Almost all of the studies (83.3%) applied multimodal or dual interventions to improve HHC. A range of strategies, including education, monitoring and providing feedback, campaigns, and cues, effectively improved HHC. The review findings indicate that there is a room for improvement in HHC in EDs. Future randomized controlled trials are necessary to determine which intervention modalities are most effective and sustainable for HHC improvement.

Building Capacity in Long-Term Care: Supporting Homes to Provide Intravenous Therapy

Background

Typically, long-term care home (LTCH) residents are transferred to hospital to access intravenous (IV) therapy. The aim of this study was to pilot-test an in-home IV therapy service, and to describe outcomes and key informants’ perceptions of this service.

Method

This service was pilot-tested in four LTCH in the Hamilton-Niagara region, Ontario. Interviews were conducted with six caregivers of residents who received IV therapy and ten key informants representing LTC home staff and service partners to assess their perceptions of the service. A chart review was conducted to describe the resident population served and service implementation.

Results

Twelve residents received IV therapy. This service potentially avoided nine emergency department visits and reduced hospital lengths of stay for three residents whose IV therapy was initiated in hospital. There were no adverse events. The service was well received by caregivers and key informants, as it provided care in a familiar environment and was perceived to be less stressful and better quality care than when provided in hospital.

Conclusion

IV therapy is feasible to implement in LTCHs, particularly when there are supportive resources available and clinical pathways to support decision-making. This service has the potential to increase capacity in LTCHs to provide medical care.

The association between adherence to levothyroxine and economic and clinical outcomes in patients with hypothyroidism in the US

OBJECTIVE

To evaluate outcomes associated with adherence to levothyroxine (LT4) in the US adult hypothyroidism population.

METHODS

We used data from Truven's MarketScan databases from 1 July 2011 through 31 December 2015. Patients aged 18 or older were diagnosed with hypothyroidism (confirmed at least twice) and prescribed LT4. Patients were excluded if they did not have continuous insurance coverage or if they received a diagnosis of thyroid cancer or pregnancy during the study period. Multivariable analyses on a matched cohort of adherent and nonadherent patients examined the relationships among patient outcomes and adherence, defined as the proportion of days covered ≥80%. Outcomes included all-cause and hypothyroidism-related medical costs and resource utilization and comorbid diagnoses measured over the 1 year post-period following the first prescription for LT4. The analyses controlled for patient age, sex, region of residence, type of insurance coverage, diagnosing physician and pre-period general health status as proxied by the Charlson Comorbidity Index.

RESULTS

Prior to matching, there were 168,457 patients identified as adherent and 198,443 patients identified as nonadherent. The matched cohort consisted of 318,628 individuals, with equal numbers of adherent and nonadherent patients (n = 159,314). Patients who were adherent used significantly fewer resources and had significantly lower all-cause ($14,136 vs. $14,926; p < .0001) and hypothyroidism-related ($1672 vs. $1709; p < .0001) total costs, although the costs of drugs were higher in the adherent group. Furthermore, adherent patients, compared to nonadherent patients, were significantly less likely to be diagnosed with comorbid Addison's disease, bipolar disorder, chronic kidney disease, depression, migraine, obesity, type 1 diabetes or type 2 diabetes during the follow-up period.

CONCLUSIONS

Compared to nonadherence, adherence to LT4 among patients with hypothyroidism was associated with a significant reduction in all-cause and hypothyroidism-related costs and resource utilization as well as significantly lower rates of many comorbid diagnoses.

Tuberculosis infection via the emergency department among inpatients in South Korea: a propensity score matched analysis of the National Inpatient Sample

BACKGROUND

Emergency departments (EDs) carry a high risk of infectious disease transmission and have also been implicated in tuberculosis (TB) outbreaks.

AIM

To determine if patients who visit EDs have an increased risk of TB infection. Using South Korean inpatient sample data (2012), the risk of TB occurrence during 90 days after hospitalization for patients admitted via EDs was compared with that for patients admitted via outpatient clinics.

METHODS

The data of the 2012 Health Insurance Review and Assessment Service - National Inpatient Sample were used. TB diagnosis was based on International Classification of Diseases Version 10 [all TB (A15-A19), pulmonary TB (A15-A16) and extrapulmonary TB (A17-A18)].

FINDINGS

After propensity score matching using the demographic and clinical characteristics of the patients, 191,997 patients (64,017 patients admitted via EDs and 127,908 patients admitted via outpatient clinics) were included in this study. There was no significant difference in baseline patient characteristics between the two groups. The percentage of patients with TB admitted via EDs was higher than that of patients admitted via outpatient clinics. The likelihood of active TB occurrence was 30% higher for all TB [hazard ratio (HR) 1.30; 95% confidence interval (CI) 1.12-1.52] and pulmonary TB (HR 1.30; 95% CI 1.10-1.53) in patients admitted via EDs compared with patients admitted via outpatient clinics; this difference was significant. However, no difference in the occurrence of extrapulmonary TB was observed between the two groups.

CONCLUSIONS

The likelihood of TB infection was greater in patients admitted via EDs than in patients admitted via outpatient clinics.

Adherence to Basal Insulin Therapy Among People with Type 2 Diabetes: A Retrospective Cohort Study of Costs and Patient Outcomes

INTRODUCTION

This research compares costs, resource utilization, and complications between adherent and nonadherent patients over the 3-year period post initiation on basal insulin therapy.

METHODS

The study utilized the US-based Truven Health MarketScan^® Research Databases from 2011 through 2015. Adults aged 18 years or older and identified with type 2 diabetes (T2D) who initiated therapy on basal insulin in 2012 were included. Patients were excluded if they were pregnant, filled their index basal insulin prescription via mail order, or were not continuously insured from 1 year before through 3 years following initiation of treatment with basal insulin. Instrumental variables were used to control for selection bias, and multivariable analyses were used to examine the associations between adherence to basal insulin therapy and costs, resource utilization, and acute complications.

RESULTS

A total of 21,363 individuals were included in the study. Three years after initiating therapy on basal insulin, patients who were adherent over time to basal insulin treatment therapy (33.8% of patients) had significantly higher diabetes-related drug costs. However, patients' adherence was associated with significantly lower diabetes-related outpatient, acute care, and total costs. Results for all-cause costs were similar. Adherent patients also had significantly fewer all-cause and diabetes-related hospitalizations and emergency room visits and were significantly less likely to be diagnosed with an acute complication.

CONCLUSIONS

Results of this study illustrate that despite higher drug costs, there are disease-specific and all-cause cost offsets and improved patient outcomes associated with adherence to basal insulin therapy for people with T2D.

The development of hand hygiene compliance imperatives in an emergency department

BACKGROUND

Monitoring results showing poor hand hygiene compliance in a major, busy emergency department prompted a quality improvement initiative to improve hand hygiene compliance.

PURPOSE

To identify, remove, and reduce barriers to hand hygiene compliance in an emergency department.

METHODS

A barrier identification tool was used to identify key barriers and opportunities associated with hand hygiene compliance. Hand hygiene imperatives were developed and agreed on with clinicians, and a framework for monitoring and improving hand hygiene compliance was developed.

RESULTS

Barriers to compliance were ambiguity about when to clean hands, the pace and urgency of work in some areas of the department, which left little time for hand hygiene and environmental and operational issues. Sore hands were a problem for some staff. Expectations of compliance were agreed on with staff, and changes were made to remove barriers. A monitoring tool was designed to monitor progress. Gradual improvement occurred in all areas, except in emergency situations, which require further improvement work.

CONCLUSIONS

The context of care and barriers to compliance should be reflected in hand hygiene expectations and monitoring. In the emergency department, the requirement to deliver urgent live-saving care can supersede conventional hand hygiene expectations.

Communicating the promise, risks, and ethics of large-scale, open space microbiome and metagenome research

The public commonly associates microorganisms with pathogens. This suspicion of microorganisms is understandable, as historically microorganisms have killed more humans than any other agent while remaining largely unknown until the late seventeenth century with the works of van Leeuwenhoek and Kircher. Despite our improved understanding regarding microorganisms, the general public are apt to think of diseases rather than of the majority of harmless or beneficial species that inhabit our bodies and the built and natural environment. As long as microbiome research was confined to labs, the public's exposure to microbiology was limited. The recent launch of global microbiome surveys, such as the Earth Microbiome Project and MetaSUB (Metagenomics and Metadesign of Subways and Urban Biomes) project, has raised ethical, financial, feasibility, and sustainability concerns as to the public's level of understanding and potential reaction to the findings, which, done improperly, risk negative implications for ongoing and future investigations, but done correctly, can facilitate a new vision of "smart cities." To facilitate improved future research, we describe here the major concerns that our discussions with ethics committees, community leaders, and government officials have raised, and we expound on how to address them. We further discuss ethical considerations of microbiome surveys and provide practical recommendations for public engagement.

Pressure Ulcers Among Newly Admitted Nursing Home Residents: Measuring the Impact of Transferring From Hospital

OBJECTIVES

Pressure ulcers (PUs) are reported more often among newly admitted nursing home (NH) residents who transfer from hospital versus community. We examine for whom this increased risk is greatest, further defining hospitalized patients most in need of better PU preventive care.

RESEARCH DESIGN

Retrospective observational cohort study.

SUBJECTS

All NH residents (N=5617) newly admitted between April 1, 2008 and March 31, 2012 in Winnipeg, MB, Canada.

MEASURES

RAI-MDS 2.0 data were linked to administrative health care use files capturing each person's NH admission date, their presence of a PU at this time, whether they transferred into NH from hospital or community, and their PU susceptibility (eg, amount of help needed to maneuver in bed or to transfer from one surface to another, frequency of incontinence, presence of diabetes, amount of food consistently left uneaten). Log-binomial regression with interaction terms was used to analyze data.

RESULTS

67.6% of our cohort transferred into a NH directly from hospital; 9.2% of these residents were reported to have a stage 1+ PU on NH admission versus 2.6% of those who transferred from community. From regression models, transferring from hospital versus community was associated with increased PU risk equally across various subgroups of less and more susceptible residents.

CONCLUSIONS

Transferring from hospital versus community places both more and less susceptible newly admitted NH residents at increased PU risk. Using evidence-based preventive care practices is thus needed for all subgroups of hospital patients before NH use, to help reduce PU risk.

A healthy degree of suspicion: A discussion of the implementation of transmission based precautions in the emergency department

Background

Emergency department (ED) presentations have increased significantly domestically and internationally. Swift identification and implementation of transmission based precautions (TBP) for patients known or suspected of having an epidemiologically important pathogen is important. ED staff, particularly triage nurses, are pivotal in detecting and preventing infection, including healthcare associated infections (HAI).

Methods

MEDLINE, CINAHL, PubMed and Ovid were searched for articles published between 2004 and 2015 using key search terms: infection control/prevention and emergency department(s), triage, and transmission based precautions and emergency department(s), and triage, to identify common themes for discussion. Systematic review/meta-analysis was not in the scope of this exploration.

Findings

Themes were identified relating to HAI and ED practices and grouped into: assisted detection of conditions for which TBP is required, ED and TBP, mass-causality event/bioterrorism/pandemic/epidemic, infection control not TBP and multi-resistant organisms not TBP. The literature is heavily influenced by worldwide epidemic/pandemics and bioterrorist risks resulting in increased awareness of the importance of swift identification of syndromes that require TBP, but only in these situations.

Conclusion

Implementation of appropriate TBP, changing triage practices, training and measures to assist decision-making could assist in preventing HAI in the ED context. A systematic quantitative review of the literature is recommended to guide practice change research.

Diversity of Bacterial Communities on Four Frequently Used Surfaces in a Large Brazilian Teaching Hospital

Frequently used hand-touch surfaces in hospital settings have been implicated as a vehicle of microbial transmission. In this study, we aimed to investigate the overall bacterial population on four frequently used surfaces using a culture-independent Illumina massively parallel sequencing approach of the 16S rRNA genes. Surface samples were collected from four sites, namely elevator buttons (EB), bank machine keyboard buttons (BMKB), restroom surfaces, and the employee biometric time clock system (EBTCS), in a large public and teaching hospital in São Paulo. Taxonomical composition revealed the abundance of Firmicutes phyla, followed by Actinobacteria and Proteobacteria, with a total of 926 bacterial families and 2832 bacterial genera. Moreover, our analysis revealed the presence of some potential pathogenic bacterial genera, including Salmonella enterica, Klebsiella pneumoniae, and Staphylococcus aureus. The presence of these pathogens in frequently used surfaces enhances the risk of exposure to any susceptible individuals. Some of the factors that may contribute to the richness of bacterial diversity on these surfaces are poor personal hygiene and ineffective routine schedules of cleaning, sanitizing, and disinfecting. Strict standards of infection control in hospitals and increased public education about hand hygiene are recommended to decrease the risk of transmission in hospitals among patients.

24/7 Registered Nurse Staffing Coverage in Saskatchewan Nursing Homes and Acute Hospital Use

La législation, dans de nombreuses juridictions, nécessite les établissements des soins de longue durée (SLD) d'avoir une infirmière en service 24 heures par jour, 7 jours par semaine. Bien que la recherche considérable existe sur l'intensité SLD de la dotation en personnel infirmier, il n'existe pas de la recherche empirique relative à cette exigence. Notre étude rétrospectif d'observation a comparé des installations en Saskatchewan avec 24/7 RN couverture aux établissements offrant moins de couverture, complétées par divers modèles de dotation des postes de nuit. Les ratios de risque associés à moins de 24/7 couverture RN complété de la dotation infirmière autorisé de nuit, ajusté pour l'intensité de dotation en personnel infirmier et d'autres facteurs de confusion potentiels, étaient de 1,17, IC 95% [0,91, 1,50] et 1.00, IC à 95% [0,72, 1,39], et avec moins de couverture 24/7 RN complété avec soin par aides personnels de nuit, les ratios de risque étaient de 1,46, IC 95% [1,11, 1,91] et 1,11, IC 95% [0,78, 1,58], pour les patients hospitalisés et de visites aux services d'urgence, respectivement. Ces résultats suggèrent que l'utilisation des soins de courte durée peut être influencée négativement par l'absence de la couverture 24/7 RN.

Older people in the emergency department: a literature review

BACKGROUND

Emergency departments (EDs) play a unique role in healthcare systems throughout the world by providing acute interventions for older patients with acute/emergency and multiple health problems. The aim of this review was to identify studies that focused on older patients admitted to EDs and to determine the reasons for the visits.

DESIGN AND METHODS

The literature review was based on a comprehensive search of electronic databases. Inclusion criteria were original research written in English; published 2002-2012; focused on older people; reasons for ED visit; and factors that affect the discharge process and those associated with a repeat ED visit. Other literature reviews and studies unrelated to the ED context, and studies examining patients aged ≥65 years, were excluded. Content analysis was performed. Twenty-five studies were identified and critically evaluated.

RESULTS

The highest proportion of older people visited the ED because of multiple health conditions. The reasons for the visits were cardiovascular, mental health, musculoskeletal and abdominal conditions; adverse drug reactions; dermatological, neurological and respiratory conditions; poor health status; accidents; and the influence of time factors such as time of day, week or season. Factors that affected the discharge process were unresolved problems, health risk identification, aftercare instructions, medication prescribed at discharge and patient's residence before ED admission. Factors associated with repeat ED visits were sociodemographic characteristics, social problems, health problems, need for systematic health assessment, healthcare service use and inadequacy of care provided.

CONCLUSIONS

The current review showed that older people are the main population visiting EDs; important factors required for planning and providing nursing care for older people in EDs were identified. More research is needed to determine how EDs support older people and their families.

IMPLICATIONS FOR PRACTICE

The findings of the current review identified that older people visit ED quite often because of different reasons. Discharge process and repeat visits may be influenced by various factors. To ensure quality nursing care in ED nurses need to be aware why do older people visit the ED, what factors may influence discharge and what factors are associated with repeat ED visits.

Are well-child visits a risk factor for subsequent influenza-like illness visits?

OBJECTIVE

To determine whether well-child visits are a risk factor for subsequent influenza-like illness (ILI) visits within a child's family.

DESIGN

Retrospective cohort.

METHODS

Using data from the Medical Expenditure Panel Survey from the years 1996-2008, we identified 84,595 families. For each family, we determined those weeks in which a well-child visit or an ILI visit occurred. We identified 23,776 well-child-visit weeks and 97,250 ILI-visit weeks. We fitted a logistic regression model, where the binary dependent variable indicated an ILI clinic visit in a particular week. Independent variables included binary indicators to denote a well-child visit in the concurrent week or one of the previous 2 weeks, the occurrence of the ILI visit during the influenza season, and the presence of children in the family in each of the age groups 0-3, 4-7, and 8-17 years. Socioeconomic variables were also included. We also estimated the overall cost of well-child-exam-related ILI using data from 2008.

RESULTS

We found that an ILI office visit by a family member was positively associated with a well-child visit in the same or one of the previous 2 weeks (odds ratio, 1.54). This additional risk translates to potentially 778,974 excess cases of ILI per year in the United States, with a cost of $500 million annually.

CONCLUSIONS

Our results should encourage ambulatory clinics to strictly enforce infection control recommendations. In addition, clinics could consider time-shifting of well-child visits so as not to coincide with the peak of the influenza season.

Burden of present-on-admission infections and health care-associated infections, by race and ethnicity

BACKGROUND

In the United States incidence of sepsis and pneumonia differ by race, but it is unclear whether this is due to intrinsic factors or health care factors.

METHODS

We conducted a study of 52,006 patients hospitalized during 2006-2008 at a referral hospital in upper Manhattan. We examined how the prevalence of present-on-admission and health care-associated infection compared between non-Hispanic blacks, Hispanics, and non-Hispanic whites adjusting for sociodemographic factors, admission through the emergency department, and comorbid conditions.

RESULTS

Non-Hispanic blacks had 1.59-fold (95% confidence interval [CI], 1.29-1.96) and 1.55-fold (95% CI, 1.35-1.77) risk of community-acquired bloodstream infection and urinary tract infection compared with non-Hispanic whites. Hispanic patients had 1.31-fold (95% CI, 1.15-1.49) risk of presenting with community-acquired urinary tract infection compared with non-Hispanic whites. Controlling for admission through the emergency department, comorbidity, and neighborhood income attenuated the differences in prevalence of infections.

CONCLUSIONS

We found that health disparities in present-on-admission infections might be largely explained by potential lack of ambulatory care, socioeconomic factors, and comorbidity.

A systematic review of outcomes following emergency transfer to hospital for residents of aged care facilities

BACKGROUND

residential aged care facility (RACF) resident numbers are increasing. Residents are frequently frail with substantial co-morbidity, functional and cognitive impairment with high susceptibility to acute illness. Despite living in facilities staffed by health professionals, a considerable proportion of residents are transferred to hospital for management of acute deteriorations in health. This model of emergency care may have unintended consequences for patients and the healthcare system. This review describes available evidence about the consequences of transfers from RACF to hospital.

METHODS

a comprehensive search of the peer-reviewed literature using four electronic databases. Inclusion criteria were participants lived in nursing homes, care homes or long-term care, aged at least 65 years, and studies reported outcomes of acute ED transfer or hospital admission. Findings were synthesized and key factors identified.

RESULTS

residents of RACF frequently presented severely unwell with multi-system disease. In-hospital complications included pressure ulcers and delirium, in 19 and 38% of residents, respectively; and up to 80% experienced potentially invasive interventions. Despite specialist emergency care, mortality was high with up to 34% dying in hospital. Furthermore, there was extensive use of healthcare resources with large proportions of residents undergoing emergency ambulance transport (up to 95%), and inpatient admission (up to 81%).

CONCLUSIONS

acute emergency department (ED) transfer is a considerable burden for residents of RACF. From available evidence, it is not clear if benefits of in-hospital emergency care outweigh potential adverse complications of transfer. Future research is needed to better understand patient-centred outcomes of transfer and to explore alternative models of emergency healthcare.

The effects of cognitive impairment on nursing home residents' emergency department visits and hospitalizations

BACKGROUND

Little is known about the relationship of cognitive impairment (CI) in nursing home (NH) residents and their use of emergency department (ED) and subsequent hospital services.

METHODS

We analyzed 2006 Medicare claims and resident assessment data for 112,412 Medicare beneficiaries aged >65 years residing in US nursing facilities. We estimated the effect of resident characteristics and severity of CI on rates of total ED visits per year, then estimated the odds of hospitalization after ED evaluation.

RESULTS

Mild CI predicted higher rates of ED visits relative to no CI, and ED visit rates decreased as severity of CI increased. In unadjusted models, mild CI and very severe CI predicted higher odds of hospitalization after ED evaluation; however, after adjusting for other factors, severity of CI was not significant.

CONCLUSIONS

Higher rates of ED visits among those with mild CI may represent a unique marker in the presentation of acute illness and warrant further investigation.

Elevator buttons as unrecognized sources of bacterial colonization in hospitals

BACKGROUND

Elevators are ubiquitous and active inside hospitals, potentially facilitating bacterial transmission. The objective of this study was to estimate the prevalence of bacterial colonization on elevator buttons in large urban teaching hospitals.

METHODS

A total of 120 elevator buttons and 96 toilet surfaces were swabbed over separate intervals at 3 tertiary care hospitals on weekdays and weekends in Toronto, Ontario. For the elevators, swabs were taken from 2 interior buttons (buttons for the ground floor and one randomly selected upper-level floor) and 2 exterior buttons (the "up" button from the ground floor and the "down" button from the upper-level floor). For the toilet surfaces, swabs were taken from the exterior and interior handles of the entry door, the privacy latch, and the toilet flusher. Samples were obtained using standard bacterial collection techniques, followed by plating, culture, and species identification by a technician blind to sample source.

RESULTS

The prevalence of colonization of elevator buttons was 61% (95% confidence interval 52%-70%). No significant differences in colonization prevalence were apparent in relation to location of the buttons, day of the week, or panel position within the elevator. Coagulase-negative staphylococci were the most common organisms cultured, whereas Enterococcus and Pseudomonas species were infrequent. Elevator buttons had a higher prevalence of colonization than toilet surfaces (61% v. 43%, p = 0.008).

CONCLUSIONS

Hospital elevator buttons were commonly colonized by bacteria, although most pathogens were not clinically relevant. The risk of pathogen transmission might be reduced by simple countermeasures.

Nursing home characteristics associated with resident transfers to emergency departments

This study examined how nursing home facility ownership and organizational characteristics relate to emergency department (ED) transfer rates. The sample included a retrospective cohort of nursing home residents in the Vancouver Coastal Health region (n = 13,140). Rates of ED transfers were compared between nursing home ownership types. Administrative data were further linked to survey-derived data of facility organizational characteristics for exploratory analysis. Crude ED transfer rates (transfers/100 resident years) were 69, 70, and 51, respectively, in for-profit, non-profit, and publicly owned facilities. Controlling for sex and age, public ownership was associated with lower ED transfer rates compared to for-profit and non-profit ownership. Results showed that higher total direct-care nursing hours per resident day, and presence of allied health staff--disproportionately present in publicly owned facilities--were associated with lower transfer rates. A number of other facility organizational characteristics--unrelated to ownership--were also associated with transfer rates.

Insights into the implementation and operation of a novel paramedic long-term care program

OBJECTIVE

An extended-care paramedic (ECP) program was implemented to provide emergency assessment and care on site to long-term care (LTC) residents suffering acute illness or injury. A single paramedic works collaboratively with physicians, LTC staff, patient, and family to develop care plans to address acute situations, often avoiding the need to transport the resident to hospital. We sought to identify insights gained and lessons learned during implementation and operation of this novel program.

METHODS

The perceptions and experiences of various stakeholders were explored in focus groups, using a semi-structured interview guide. Two investigators independently conducted thematic analysis and identified emerging themes and related codes. Congruence and differences were discussed to achieve consensus.

RESULTS

Twenty-one participants took part in four homogeneous focus groups: paramedics and dispatchers, ECPs, ECP oversight physicians, and decision-makers. The key themes identified were (1) program implementation, (2) ECP process of care, (3) communications, and (4) end-of-life care.

CONCLUSION

The ECP program has positive implications for the relationship between EMS and LTC, requires additional paramedic training, and can positively affect LTC patient experiences during acute medical events. ECPs have a novel role to play in end-of-life care and find this new role rewarding.

Trends in the burden of infectious disease hospitalizations among the elderly in the last decade

BACKGROUND

Infectious disease is a leading cause of hospitalization. We investigated trends in infectious disease hospitalizations among the elderly in the last decade.

METHODS

A total of 81,077 hospitalizations of elderly patients between 2001 and 2010 were available on the computerized database of the Ha'emek Medical Center, Israel. The proportion of hospitalizations attributable to infectious diseases was calculated.

RESULTS

Overall, lower respiratory tract infection (LRTI) accounted for 41.0% of hospitalizations attributable to infectious diseases followed by kidney, urinary tract and bladder infections (UTI) (21.4%), upper respiratory tract infections (URTI) (10.2%), and hepatobiliary tract infections (9.8%). The proportion of hospitalizations attributable to infectious diseases increased by 14.2% during the study period, rising from 16.9% in 2001 (1023 infectious disease hospitalizations of a total of 6043 hospitalizations) to 19.3% in 2010 (1907 infectious disease hospitalizations of a total of 9876 hospitalizations) (P for trend<0.001). A significant increasing trend persisted after adjustment for age, ethnicity, and season, resulting in an increase from 16.9% in 2001 to 18.8% in 2010 (P for trend=0.001). A significant increasing trend was observed in males (P for trend<0.001) and a borderline significant trend was observed in females (P for trend=0.062). The proportion of hospitalizations attributable to infectious diseases was higher in males and increased with age. LRTI and URTI were the major contributors to the increasing trend (P for trend=0.018 and <0.001, respectively).

CONCLUSIONS

This study shows an increasing trend in infectious disease hospitalizations among the elderly in the last decade. Public health measures are needed to reduce infectious disease hospitalizations.

Measuring social contacts in the emergency department

Background

Infectious individuals in an emergency department (ED) bring substantial risks of cross infection. Data about the complex social and spatial structure of interpersonal contacts in the ED will aid construction of biologically plausible transmission risk models that can guide cross infection control.

Methods and Findings

We sought to determine the number and duration of contacts among patients and staff in a large, busy ED. This prospective study was conducted between 1 July 2009 and 30 June 2010. Two 12-hour shifts per week were randomly selected for study. The study was conducted in the ED of an urban hospital. There were 81 shifts in the planned random sample of 104 (78%) with usable contact data, during which there were 9183 patient encounters. Of these, 6062 (66%) were approached to participate, of which 4732 (78%) agreed. Over the course of the year, 88 staff members participated (84%). A radiofrequency identification (RFID) system was installed and the ED divided into 89 distinct zones structured so copresence of two individuals in any zone implied a very high probability of contact <1 meter apart in space. During study observation periods, patients and staff were given RFID tags to wear. Contact events were recorded. These were further broken down with respect to the nature of the contacts, i.e., patient with patient, patient with staff, and staff with staff. 293,171 contact events were recorded, with a median of 22 contact events and 9 contacts with distinct individuals per participant per shift. Staff-staff interactions were more numerous and longer than patient-patient or patient-staff interactions.

Conclusions

We used RFID to quantify contacts between patients and staff in a busy ED. These results are useful for studies of the spread of infections. By understanding contact patterns most important in potential transmission, more effective prevention strategies may be implemented.
