Infection in home health care: Results from national Outcome and Assessment Information Set data

Diagnostic uncertainty and decision-making in home-based primary care: A qualitative study of antibiotic prescribing

BACKGROUND

Evaluating infection in home-based primary care is challenging, and these challenges may impact antibiotic prescribing. A refined understanding of antibiotic decision-making in this setting can inform strategies to promote antibiotic stewardship. This study investigated antibiotic decision-making by exploring the perspectives of clinicians in home-based primary care.

METHODS

Clinicians from the Department of Veterans Affairs Home-Based Primary Care Program were recruited. Semi-structured interviews were conducted from June 2022 through September 2022 using a discussion guide. Transcripts were analyzed using grounded theory. The constant comparative method was used to develop a coding structure and to identify themes.

RESULTS

Theoretical saturation was reached after 22 clinicians (physicians, n = 7; physician assistants, n = 2, advanced practice registered nurses, n = 13) from 19 programs were interviewed. Mean age was 48.5 ± 9.3 years, 91% were female, and 59% had ≥6 years of experience in home-based primary care. Participants reported uncertainty about the diagnosis of infection due to the characteristics of homebound patients (atypical presentations of disease, presence of multiple chronic conditions, presence of cognitive impairment) and the challenges of delivering medical care in the home (limited access to diagnostic testing, suboptimal quality of microbiological specimens, barriers to establishing remote access to the electronic health record). When faced with diagnostic uncertainty about infection, participants described many factors that influenced the decision to prescribe antibiotics, including those that promoted prescribing (desire to avoid hospitalization, pressure from caregivers, unreliable plans for follow-up) and those that inhibited prescribing (perceptions of antibiotic-associated harms, willingness to trial non-pharmacological interventions first, presence of caregivers who were trusted by clinicians to monitor symptoms).

CONCLUSIONS

Clinicians face the difficult task of balancing diagnostic uncertainty with many competing considerations during the treatment of infection in home-based primary care. Recognizing these issues provides insight into strategies to promote antibiotic stewardship in home care settings.

Uncovering hidden trends: identifying time trajectories in risk factors documented in clinical notes and predicting hospitalizations and emergency department visits during home health care

OBJECTIVE

This study aimed to identify temporal risk factor patterns documented in home health care (HHC) clinical notes and examine their association with hospitalizations or emergency department (ED) visits.

MATERIALS AND METHODS

Data for 73 350 episodes of care from one large HHC organization were analyzed using dynamic time warping and hierarchical clustering analysis to identify the temporal patterns of risk factors documented in clinical notes. The Omaha System nursing terminology represented risk factors. First, clinical characteristics were compared between clusters. Next, multivariate logistic regression was used to examine the association between clusters and risk for hospitalizations or ED visits. Omaha System domains corresponding to risk factors were analyzed and described in each cluster.

RESULTS

Six temporal clusters emerged, showing different patterns in how risk factors were documented over time. Patients with a steep increase in documented risk factors over time had a 3 times higher likelihood of hospitalization or ED visit than patients with no documented risk factors. Most risk factors belonged to the physiological domain, and only a few were in the environmental domain.

DISCUSSION

An analysis of risk factor trajectories reflects a patient's evolving health status during a HHC episode. Using standardized nursing terminology, this study provided new insights into the complex temporal dynamics of HHC, which may lead to improved patient outcomes through better treatment and management plans.

CONCLUSION

Incorporating temporal patterns in documented risk factors and their clusters into early warning systems may activate interventions to prevent hospitalizations or ED visits in HHC.

Risk factors for infection in older adults who receive home healthcare and/or home help: A protocol for systematic review and meta-analysis

BACKGROUND

The shift towards home-based care has resulted in increased provision of home healthcare and home help to older adults. Infections acquired in older adults while receiving home care have increased too, resulting in unplanned yet avoidable hospitalizations. In recent years, several studies have reported an array of factors associated with risk of infection; however, no previous systematic review has compiled such evidence, which is important to better protect older adults. Therefore, we have outlined the work of a systematic review that aims to identify risk factors for infection in older adults receiving home healthcare and/or home help.

METHODS

Searches for relevant studies will be conducted in five databases [MEDLINE, EMBASE (Excerpta Medica Database), Web of Science Core Collection, Cinahl (Cumulative Index to Nursing & Allied Health Literature) and Sociological Abstracts]. All types of studies will be included. Exposures considered refer to medical, individual, social/behavioral and environmental risk factors for infection (outcome). Two researchers will independently go through the records generated. Eligible studies will be assessed for risk of biases using the Cochrane risk of bias assessment tool and an overall interpretation of the biases will be provided. If the data allow, a meta-analysis will be conducted. It is possible that both quantitative and qualitative studies will be identified and eligible. Therefore, for the analysis, the Joanna Briggs Institute Reviewers' Manual for mixed methods systematic reviews will be used as it allows for two or more single method reviews (e.g., one quantitative and one qualitative) to be conducted separately and then combined in a joint overarching synthesis.

RESULTS

The findings of the planned systematic review are of interest to healthcare professionals, caregivers, older adults and their families, and policy- and decisions makers in the health and social care sectors as the review will provide evidence-based data on multiple factors that influence the risk of infection among older adults receiving care in their homes.

CONCLUSION

The results could guide future policy on effective infection control in the home care sector.

National Cohort Study of Homebound Persons Living With Dementia: Antibiotic Prescribing Trends and Opportunities for Antibiotic Stewardship

Background

Over 7 million older Americans are homebound. Managing infections in homebound persons presents unique challenges that are magnified among persons living with dementia (PLWD). This work sought to characterize antibiotic use in a national cohort of PLWD who received home-based primary care (HBPC) through the Veterans Health Administration.

Methods

Administrative data identified veterans aged ≥65 years with ≥2 physician home visits in a year between 2014 and 2018 and a dementia diagnosis 3 years before through 1 year after their initial HBPC visit. Antibiotics prescribed orally, intravenously, intramuscularly, or by enema within 3 days of an HBPC visit were assessed from the initial HBPC visit to death or December 31, 2018. Prescription fills and days of therapy (DOT) per 1000 days of home care (DOHC) were calculated.

Results

Among 39 861 PLWD, the median age (interquartile range [IQR]) was 85 (78-90) years, and 15.0% were Black. Overall, 16 956 (42.5%) PLWD received 45 122 prescription fills. The antibiotic use rate was 20.7 DOT per 1000 DOHC. Telephone visits and advanced practice provider visits were associated with 30.9% and 42.0% of fills, respectively. Sixty-seven percent of fills were associated with diagnoses for conditions where antibiotics are not indicated. Quinolones were the most prescribed class (24.3% of fills). The overall median length of therapy (IQR) was 7 (7-10) days. Antibiotic use rates varied across regions. Within regions, the median annual antibiotic use rate decreased from 2014 to 2018.

Conclusions

Antibiotic prescriptions were prevalent in HBPC. The scope, appropriateness, and harms of antibiotic use in homebound PLWD need further investigation.

Urinary catheter policies in home healthcare agencies and hospital transfers due to urinary tract infection

BACKGROUND

Urinary tract infections (UTIs) are a frequent cause of hospital transfer for home healthcare (HHC) patients, particularly among patients with urinary catheters.

METHODS

We conducted a cross-sectional, nationally representative HHC agency-level survey (2018-2019) and combined it with patient-level data from the Outcome and Assessment Information Set (OASIS) and Medicare inpatient data (2016-2018) to evaluate the association between HHC agencies' urinary catheter policies and hospital transfers due to UTI. Our sample included 28,205 patients with urinary catheters who received HHC from 473 Medicare-certified agencies between 2016-2018. Our survey assessed whether agencies had written policies in place for (1) replacement of indwelling catheters at fixed intervals, and (2) emptying the drainage bag. We used adjusted logistic regression to estimate the association of these policies with probability of hospital transfer due to UTI during a 60-day HHC episode.

RESULTS

Probability of hospital transfer due to UTI during a HHC episode ranged from 5.62% among agencies with neither urinary catheter policy to 4.43% among agencies with both policies. Relative to agencies with neither policy, having both policies was associated with 21% lower probability of hospital transfer due to UTI (P < .05).

CONCLUSION

Our findings suggest implementation of policies in HHC to promote best practices for care of patients with urinary catheters may be an effective strategy to prevent hospital transfers due to UTI.

Do nurses document all discussions of patient problems and nursing interventions in the electronic health record? A pilot study in home healthcare

Objective

To assess the overlap of information between electronic health record (EHR) and patient–nurse verbal communication in home healthcare (HHC).

Methods

Patient–nurse verbal communications during home visits were recorded between February 16, 2021 and September 2, 2021 with patients being served in an organization located in the Northeast United States. Twenty-two audio recordings for 15 patients were transcribed. To compare overlap of information, manual annotations of problems and interventions were made on transcriptions as well as information from EHR including structured data and clinical notes corresponding to HHC visits.

Results

About 30% (1534/5118) of utterances (ie, spoken language preceding/following silence or a change of speaker) were identified as including problems or interventions. A total of 216 problems and 492 interventions were identified through verbal communication among all the patients in the study. Approximately 50.5% of the problems and 20.8% of the interventions discussed during the verbal communication were not documented in the EHR. Preliminary results showed that statistical differences between racial groups were observed in a comparison of problems and interventions.

Discussion

This study was the first to investigate the extent that problems and interventions were mentioned in patient–nurse verbal communication during HHC visits and whether this information was documented in EHR. Our analysis identified gaps in information overlap and possible racial disparities.

Conclusion

Our results highlight the value of analyzing communications between HHC patients and nurses. Future studies should explore ways to capture information in verbal communication using automated speech recognition.

Clinical notes: An untapped opportunity for improving risk prediction for hospitalization and emergency department visit during home health care

BACKGROUND/OBJECTIVE

Between 10 and 25% patients are hospitalized or visit emergency department (ED) during home healthcare (HHC). Given that up to 40% of these negative clinical outcomes are preventable, early and accurate prediction of hospitalization risk can be one strategy to prevent them. In recent years, machine learning-based predictive modeling has become widely used for building risk models. This study aimed to compare the predictive performance of four risk models built with various data sources for hospitalization and ED visits in HHC.

METHODS

Four risk models were built using different variables from two data sources: structured data (i.e., Outcome and Assessment Information Set (OASIS) and other assessment items from the electronic health record (EHR)) and unstructured narrative-free text clinical notes for patients who received HHC services from the largest non-profit HHC organization in New York between 2015 and 2017. Then, five machine learning algorithms (logistic regression, Random Forest, Bayesian network, support vector machine (SVM), and Naïve Bayes) were used on each risk model. Risk model performance was evaluated using the F-score and Precision-Recall Curve (PRC) area metrics.

RESULTS

During the study period, 8373/86,823 (9.6%) HHC episodes resulted in hospitalization or ED visits. Among five machine learning algorithms on each model, the SVM showed the highest F-score (0.82), while the Random Forest showed the highest PRC area (0.864). Adding information extracted from clinical notes significantly improved the risk prediction ability by up to 16.6% in F-score and 17.8% in PRC.

CONCLUSION

All models showed relatively good hospitalization or ED visit risk predictive performance in HHC. Information from clinical notes integrated with the structured data improved the ability to identify patients at risk for these emergent care events.

Influenza vaccination of home health care staff and the impact on patient hospitalizations

BACKGROUND

Influenza is associated with significant morbidity and mortality for adults aged 65 years and older. Influenza vaccination of health care workers is recommended. There is limited evidence regarding influenza vaccinations among health care workers in the home health care (HHC) setting and their impact on HHC patient outcomes.

METHODS

A national survey of HHC agencies was conducted in 2018-2019 and linked with patient data from the Centers for Medicare and Medicaid Services. Adjusted logistic regression models were used to estimate the association between hospital transfers due to respiratory infection during a 60 day HHC episode and staff vaccination policies.

RESULTS

Only 26.2% of HHC agencies had staff vaccination requirements and 71.2% agencies had staff vaccination rates higher than 75%. Agency policies for staff influenza vaccination were associated with reduced hospital transfers due to respiratory infection among HHC patients.

DISCUSSION

Influenza vaccination rates among HHC staff were low during the 2017-2018 influenza season. Policymakers may consider vaccination mandates to improve health care worker vaccination rates and protect patient safety.

CONCLUSIONS

This study sheds light on the potential impact of COVID-19 vaccination among HHC workers on patient outcomes. COVID-19 vaccination mandates could prove to be a vital tool in the fight against COVID-19 variants and infection outbreaks.

Is ANTT Achievable in the Home Healthcare Setting?

At the heart of infection prevention in the home care setting is aseptic technique, a generic term for the clinical competency of ensuring asepsis during invasive clinical procedures and the maintenance of invasive medical devices. Variable terminology has resulted in confused education and clinical practice. Ambiguity has played out in all care environments, but especially in the home, where the challenge of providing effective aseptic technique is complicated by unique environmental and logistical factors. This has led some to conclude that aseptic technique is not possible in the home, or that it is not required at all in certain situations. This article challenges these assumptions and outlines the Aseptic Non Touch Technique (ANTT®) Clinical Practice Framework, that is used widely internationally. Through a thematic analysis of focus group discussions with home care nurses (n = 107) in the United Kingdom and the United States, opinions about aseptic practice in the home care setting were examined. Three main polarizing themes were identified and used to discuss theory and practice applications of aseptic technique for home healthcare nurses. Specific challenges in performing aseptic technique in home-based settings are exacerbated by ambiguity between what constitutes "clean," "aseptic," or so-called "sterile" technique, and are perpetuated by a lack of competency-based training that doesn't reflect the critical importance of aseptic technique to patient safety. Rather than continuing an endless debate about the definition of aseptic technique, ANTT has redefined aseptic technique education and clinical practice, with a comprehensive clinical practice framework and associated clinical governance better supporting patient safety.

Hygiene management for long-term ventilated persons in the home health care setting: a scoping review

Background

Evidence and recommendations for hygiene management in home mechanical ventilation (HMV) are rare. In Germany, few regionally limited studies show poor hygiene management or a lack of its implementation. This scoping review of international literature identified the evidence in hygiene management for ventilated patients in the home care setting which has to be implemented for infection prevention and control.

Methods

A review of international literature was conducted in CINAHL, PubMed and Web of Science. The search focused on four key domains: HMV, hygiene management, home care setting, and methicillin-resistant Staphylococcus aureus (MRSA). Data of included studies were extracted using a data charting sheet. Extracted data were assigned to the categories (1) study description, (2) setting and participants, and (3) hygiene management.

Results

From 1,718 reviewed articles, n = 8 studies met inclusion criteria. All included studies had a quantitative study design. The approaches were heterogeneous due to different settings, study populations and types of ventilation performed. Regarding aspects of hygiene management, most evidence was found for infectious critical activities (n = 5), quality management for hygiene (n = 4), and training and education (n = 4). This review identified research gaps concerning kitchen hygiene, relatives and visitors of HMV patients, and waste management (n = 0).

Discussion

Overall evidence was rather scarce. Consequently, this review could not answer all underlying research questions. No evidence was found for measures in hygiene management relating to ventilated patients’ relatives. Evidence for kitchen hygiene, waste management and interaction with relatives is available for inpatient care settings. However, this may not be transferable to outpatient care. Binding legal requirements and audits may help regulate the implementation of HMV hygiene measures.

Conclusion

Infection control programmes included qualified personnel, hygiene plans, and standards for MRSA and multidrug-resistant organisms (MDRO). The appropriateness of hygiene management measures for outpatient care is the basis for their application in practice.

Factors in Avoidable Emergency Visits for Ambulatory Care-sensitive Conditions among Older Patients Receiving Home Care in Japan: A Retrospective Study

Objective Older adults have many health conditions that do not require hospitalization, such as cognitive decline and progression of frailty, so it is necessary to prevent avoidable emergency visits for ambulatory care-sensitive conditions (ACSCs) in this population. We therefore examine Freund's classification of reasons for hospitalization owing to ACSCs to identify factors involved in elderly patients visiting emergency departments in Japan. Methods This retrospective case-control study included patients who received emergency transport for medical treatment at Yushoukai Home Care Clinic Shinagawa in Japan between January 1, 2016, and April 30, 2019. We examined patients' medical records and categorized the reasons for emergency visit by ambulance in accordance with Freund's categories (physician related level, medical causes, patient level, and social level). In addition, we classified and compared patients who lived at home (Group A) with those living in a care facility for older adults (Group B). Results A total of 365 patients visited the emergency department (298 in Group A and 67 in Group B). Among these, we determined that emergency visits were potentially avoidable in 135 patients from Group A and 28 from Group B. The patient and social level categories accounted for 81% of potentially avoidable emergency visits. Confirmed advanced care planning (ACP) was significantly associated with avoidable emergency visit by ambulance in multivariate analyses. Conclusion To prevent emergency visits for ACSCs among older people, ACP should be encouraged.

Exploring infection prevention practices in home-based nursing care: A qualitative observational study

BACKGROUND

Home-based nursing care continues to expand, delivering care to increasingly older clients with multiple, chronic and complex conditions that require the use of additional and more numerous invasive medical devices. Therefore, the prevention of infections poses a challenge for nurses, professional caregivers and clients.

OBJECTIVE

This article explores infection prevention practices and related behavioural factors in both nurses and clients to identify barriers and facilitators of infection prevention practices in home-based nursing care.

DESIGN

A qualitative, exploratory design.

SETTING

Four healthcare organisations providing home-based nursing care in the Netherlands.

METHODS

Participant observations were used as the main source of data collection complemented with focus group discussions and semi-structured interviews.

PARTICIPANTS

Participant observations: 16 nurses, three professional caregivers and 80 clients. Semi-structured interviews: 11 clients. Focus group discussions: 15 nurses and four professional caregivers.

RESULTS

A total of 87 unique care delivery situations were observed for 55 h, complemented with three focus group discussions and 11 individual semi-structured client interviews. Infection prevention practices in home-based nursing care appeared to be challenged by 1. The specific context or environment in which the care occurred, which is more autonomous, less structured, less controlled and less predictable than other care settings; 2. Suboptimal and considerable variation in professional performance concerning the application of hand hygiene and the proper use of personal protective equipment such as face masks, barrier gowns and disposable gloves; 3. Extensive use in and outside the client's surroundings of communication devices that are irregularly cleaned and tend to interrupt nursing procedures; and 4. Inadequate organisational support in the implementation and evaluation of new information or policy changes and fragmentation, variation and conflicting information regarding professional guidelines and protocols.

CONCLUSIONS

From a first-hand observational viewpoint, this study showed that the daily practice of infection prevention in home-based nursing care appears to be suboptimal. Furthermore, this research revealed considerable variation in the work environment, the application of hand hygiene, the proper use of personal protective equipment, the handling of communication devices and organisational policies, procedures and support. Finally, the study identified a number of important barriers and facilitators of infection prevention practices in the work environment, professional and team performance, clients and organisations.

Association of a Substance Use Disorder with Infectious Diseases among Adult Home Healthcare Patients with a Venous Access Device

Substance use disorders (SUDs) and high incidence of infectious diseases are both critical public health issues. Among patients who use a venous access device (VAD) in home care settings, SUDs may play a role in increasing their risk of having a concurrent infectious disease. This study examined the association of SUD with infectious diseases among adult home healthcare patients with a VAD. We identified adult patients with an existing VAD who were admitted to a home healthcare agency August 1, 2017-July 31, 2018 from the electronic health records of a large Medicare-certified agency. Four serious infectious diseases (endocarditis, epidural abscess, septic arthritis, and osteomyelitis) and SUD related to injectable drugs were identified using relevant ICD-10 codes. Multiple logistic regression was performed to examine the association. Of 416 patients with a VAD, 12% (n = 50) had at least one diagnosis of a serious infectious disease. The percentage of patients who had a serious infectious disease was 40% among those with SUDs, compared with only 11% among those without SUDs. After adjusting for age and sex, the odds of having a serious infectious disease was 3.52 times greater for those with SUDs compared with those without (odds ratio [95% confidence interval], 4.52 [1.48-13.79], n = .008). Our findings suggest that home healthcare patients with a VAD and a documented SUD diagnosis may have an increased risk of having a concurrent serious infectious disease. Therefore, patients with an SUD and a VAD would need more attention from home healthcare providers to prevent a serious infectious disease. Further research is suggested on modalities of care for individuals with an SUD and VAD to reduce the incidence of infectious diseases so that care can be delivered safely and efficiently in a home healthcare setting.

Hand hygiene by the nursing team in home care: a cross-sectional study

OBJECTIVE

to identify whether nursing professionals carry out hand hygiene, how they do it, and what resources are available for this practice during home visits.

METHOD

cross-sectional study conducted in a public Home Care service. The World Health Organization instrument was used to observe the hand hygiene technique, the time of performance, and the product used.

RESULTS

a total of 940 hand hygiene opportunities taking place in 231 home visits were observed. Overall adherence was 14.4%, with the practice of hand hygiene being higher after contact with the patient (53.7%). Before aseptic procedures, after risk/exposure to body fluids, after contact with the patient's environment, and before contact with the patient, adherence was 0.4%. Regarding the quality of the technique, in none of the 135 practices the recommended steps were followed. As for the structure available in the households, 35 (15.2%) had accessible sinks and none had liquid soap and alcohol-based formulation.

CONCLUSION

adherence to hand hygiene by nursing professionals in home care was low, the technique was not performed, and households did not have resources for the practice.

Continuity of Nursing Care in Home Health: Impact on Rehospitalization Among Older Adults With Dementia

BACKGROUND

Home health care (HHC) is a leading form of home and community-based services for persons with dementia (PWD). Nurses are the primary providers of HHC; however, little is known of nursing care delivery and quality.

OBJECTIVE

The objective of this study was to examine the association between continuity of nursing care in HHC and rehospitalization among PWD.

RESEARCH DESIGN

This is a retrospective cohort study using multiple years (2010-2015) of HHC assessment, administrative, and human resources data from a large urban not-for-profit home health agency.

SUBJECTS

This study included 23,886 PWD receiving HHC following a hospitalization.

MEASURES

Continuity of nursing care was calculated using the Bice and Boxerman method, which considered the number of total visits, nurses, and visits from each nurse during an HHC episode. The outcome was all-cause rehospitalization during HHC. Risk-adjusted logistic regression was used for analysis.

RESULTS

Approximately 24% of PWD were rehospitalized. The mean continuity of nursing care score was 0.56 (SD=0.33). Eight percent of PWD received each nursing visit from a different nurse (no continuity), and 26% received all visits from one nurse during an HHC episode (full continuity). Compared with those receiving high continuity of nursing care (third tertile), PWD receiving low (first tertile) or moderate (second tertile) continuity of nursing care had an adjusted odds ratio of 1.33 (95% confidence interval: 1.25-1.46) and 1.30 (95% confidence interval: 1.22-1.43), respectively, for being rehospitalized.

CONCLUSIONS

Wide variations exist in continuity of nursing care to PWD. Consistency in nurse staff when providing HHC visits to PWD is critical for preventing rehospitalizations.

Infection prevention and control practice among home-care nursing agencies in Japan: Secondary analysis of a nationwide cross-sectional survey

Aim

We describe the nationwide situation of infection prevention and control (IPC) practices among home‐visit nursing agencies and compare them by agency size to explore whether these practices are associated with the occurrence of infection.

Methods

We conducted a secondary analysis using data from a cross‐sectional nationwide survey inspecting patient safety and IPC practices among nationwide home‐visit nursing agencies, from March to April 2020. Among 9978 agencies, 580 responded and 370 were incorporated in the analysis. The self‐administered questionnaire inquired about the IPC policy and administrative structure, education and training, adherence to standard precautions, and employee health programs. We described the adherence to IPC practice at the agency level and compared them by agency size using chi‐squared tests. Logistic regression analysis was performed to explore the associations between IPC practices and incidence of infection.

Results

Adherence to IPC practices ranged from 19.2% to 92.4% and varied according to agency size. Less than 20% of agencies had instituted a committee for IPC and strictly used disposable aprons when changing patients' diapers. Instituting a committee for IPC (odds ratio 2.19, 95% confidence interval 1.11–4.34, P < 0.05) and training staff for infection prevention (odds ratio 1.67, 95% confidence interval 1.02–2.72, P < 0.01) were significantly associated with the incidence of infection, after adjusting for covariates.

Conclusions

There are challenges in establishing IPC policies and administrative structures and adhering to standard precautions. Well‐organized agencies were found to be more likely to detect infections occurring over the past 3 months. Geriatr Gerontol Int 2021; 21: 913–918.

Antimicrobial Resistance and Antimicrobial Stewardship in Home Healthcare

Antimicrobial resistance, the ability of microbes to become resistant to known antimicrobial medications, is a growing and serious global health concern. There are growing numbers of publications about efforts to educate nurses about antimicrobial resistance, and efforts to involve nurses in antimicrobial stewardship in acute and long-term care settings; however, this has not been the case in home care. Home care organizations are required to address infection control and surveillance, including patient, family, and staff education. Home care nurses play an important role in identifying infections, performing cultures, and teaching patients and families. This article provides an overview of antimicrobial resistance and antimicrobial stewardship and provides antimicrobial stewardship actions for home care nurses and agencies. In the interest of public health, home care agencies and nurses can, and should, educate themselves and patients about antimicrobial resistance and employ antimicrobial stewardship strategies.

Patient and Family Engagement in Catheter-Associated Urinary Tract Infection (CAUTI) Prevention: A Systematic Review

BACKGROUND

Catheter-associated urinary tract infections (CAUTIs) are detrimental to health and are largely preventable with adherence to CAUTI prevention guidelines. Patient and family engagement in CAUTI prevention is often encouraged in these guidelines; however, little is known about how this engagement is operationalized in practice. A systematic review was conducted to synthesize the content, format, and outcomes of interventions that engage patients and/or families in CAUTI prevention.

METHODS

Two reviewers independently screened records from four databases up to March 2021 and searched reference lists of final articles. Included articles were primary research, tested an intervention, involved indwelling urinary catheters, and described at least one patient and/or family engagement method. Articles were appraised for quality using the Downs and Black checklist.

RESULTS

After 720 records were screened, 12 were included. Study quality ranged from good to poor, scoring lowest in internal validity. The most common formats of patient/family engagement were flyers/handouts (83.3%) and verbal education (58.3%). Common content areas were urinary catheter care and maintenance strategies. Most study outcomes (83.3%) measured CAUTI rates, and half measured patient/family-related outcomes. Improvements were seen in at least one outcome across all studies, but less than half (41.7%) showed statistically significant results.

CONCLUSION

The researchers found that most interventions lacked sufficient detail on the content, delivery, and/or outcome measurement of patient/family engagement, which limits transferability. More high-quality, generalizable trials are warranted in this area. Future research should focus on integrating publicly available resources into practice that can be tested for comprehension and revised based on feedback from target audiences.

Predictive Risk Models for Wound Infection-Related Hospitalization or ED Visits in Home Health Care Using Machine-Learning Algorithms

OBJECTIVE

Wound infection is prevalent in home healthcare (HHC) and often leads to hospitalizations. However, none of the previous studies of wounds in HHC have used data from clinical notes. Therefore, the authors created a more accurate description of a patient's condition by extracting risk factors from clinical notes to build predictive models to identify a patient's risk of wound infection in HHC.

METHODS

The structured data (eg, standardized assessments) and unstructured information (eg, narrative-free text charting) were retrospectively reviewed for HHC patients with wounds who were served by a large HHC agency in 2014. Wound infection risk factors were identified through bivariate analysis and stepwise variable selection. Risk predictive performance of three machine learning models (logistic regression, random forest, and artificial neural network) was compared.

RESULTS

A total of 754 of 54,316 patients (1.39%) had a hospitalization or ED visit related to wound infection. In the bivariate logistic regression, language describing wound type in the patient's clinical notes was strongly associated with risk (odds ratio, 9.94; P < .05). The areas under the curve were 0.82 in logistic regression, 0.75 in random forest, and 0.78 in artificial neural network. Risk prediction performance of the models improved (by up to 13.2%) after adding risk factors extracted from clinical notes.

CONCLUSIONS

Logistic regression showed the best risk prediction performance in prediction of wound infection-related hospitalization or ED visits in HHC. The use of data extracted from clinical notes can improve the performance of risk prediction models.

Home infusions of natalizumab for people with multiple sclerosis: a pilot randomised crossover trial

OBJECTIVE

The delivery of healthcare at home has expanded to intravenous infusions of monoclonal antibodies. A recently developed model of care for home infusions of natalizumab for people with relapsing-remitting multiple sclerosis was evaluated. This pilot study of home infusions of natalizumab and usual care (attendance in a hospital out-patients' clinic) compared safety, feasibility, patient satisfaction, effectiveness and costs.

METHODS

In this randomised AB/BA crossover trial, 37 adults were randomised to usual care (n = 19) or home infusions (n = 18). After three infusions, patients crossed over to the alternate treatment for another three infusions. Patient safety outcomes and adherence, satisfaction, quality of life, disability and costs were compared.

RESULTS

No adverse events were recorded from 207 infusions from 35 patients across both home and clinic infusions. There was no difference in adherence (p = 0.71) and infection rates (p = 0.84) between home and clinic settings. Satisfaction with "convenience" of home infusions was significantly greater (p = 0.008) but there were no differences in quality of life measures. Excluding pharmacy, costs were A$74 lower per infusion at home, including A$16 of patients" out-of-pocket costs.

INTERPRETATION

There were no differences in safety and effectiveness between clinic and home infusions of natalizumab. The home infusions were shown to be feasible, more convenient and less expensive than usual care. Larger scale studies are required to verify these preliminary findings, particularly around safety and management of hypersensitivity adverse events in the home setting and for equivalence of clinical outcomes.

Exploring prevalence of wound infections and related patient characteristics in homecare using natural language processing

We aimed to create and validate a natural language processing algorithm to extract wound infection-related information from nursing notes. We also estimated wound infection prevalence in homecare settings and described related patient characteristics. In this retrospective cohort study, a natural language processing algorithm was developed and validated against a gold standard testing set. Cases with wound infection were identified using the algorithm and linked to Outcome and Assessment Information Set data to identify related patient characteristics. The final version of the natural language processing vocabulary contained 3914 terms and expressions related to the presence of wound infection. The natural language processing algorithm achieved overall good performance (F-measure = 0.88). The presence of wound infection was documented for 1.03% (n = 602) of patients without wounds, for 5.95% (n = 3232) of patients with wounds, and 19.19% (n = 152) of patients with wound-related hospitalisation or emergency department visits. Diabetes, peripheral vascular disease, and skin ulcer were significantly associated with wound infection among homecare patients. Our findings suggest that nurses frequently document wound infection-related information. The use of natural language processing demonstrated that valuable information can be extracted from nursing notes which can be used to improve our understanding of the care needs of people receiving homecare. By linking findings from clinical nursing notes with additional structured data, we can analyse related patients' characteristics and use them to develop a tailored intervention that may potentially lead to reduced wound infection-related hospitalizations.

Infection prevention and control practices in the home environment: Examining enablers and barriers to adherence among home health care nurses

BACKGROUND

Infection Prevention and Control (IPC) practices have been established in home health care. Adherence to IPC practices has been suboptimal with limited available evidence. The study aim was to examine the impact of individual, home environment, and organizational factors on IPC practices using human factors model.

METHODS

Three hundred and fifty-three nurses were surveyed across two large home care agencies to examine the relationship between IPC adherence and individual, home environment, and organizational factors.

RESULTS

Nurses reported multiple barriers to IPC practices in patients' homes (mean = 4.34, standard deviation = 2.53). Frequent barriers included clutter (reported by 74.5% of nurses) and a dirty environment (70.3%). Nurses also reported limited availability of some IPC supplies (mean = 7.76, standard deviation = 2.44), including personal protective equipment. Home environment factors were significant barriers, and availability of IPC supplies were significant enablers of IPC adherence. Agency-provided training and decision-making resources were not significant factors for IPC adherence in the presence of home environment barriers and IPC supplies.

CONCLUSIONS

This study findings suggest that IPC adherence strategies point to addressing barriers in the home environment and increasing availability of IPC supplies. The relationship between the patient's home environment, organizational factors, and IPC practices among home health care nurses warrants further study.

Individual, social, and environmental factors for infection risk among home healthcare patients: A multi-method study

There has been limited research into the individual, social, and environmental factors for infection risk among patients in the home healthcare (HHC) setting, where the infection is a leading cause of hospitalisation. The aims of this study were to (1) explore nurse perceptions of individual, social, and environmental factors for infection risk among HHC patients; and (2) identify the frequency of environmental barriers to infection prevention and control in HHC. Data were collected in 2017-2018 and included qualitative interviews with HHC nurses (n = 50) and structured observations of nurse visits to patients' homes (n = 400). Thematic analyses of interviews with nurses suggested they perceived infection risk among patients as being influenced by knowledge of and attitudes towards infection prevention and engagement in hygiene practices, receipt of support from informal caregivers and nurse interventions aimed at cultivating infection control knowledge and practices, and the home environment. Statistical analyses of observation checklists revealed nurses encountered an average of 1.7 environmental barriers upon each home visit. Frequent environmental barriers observed during visits to HHC patients included clutter (39.5%), poor lighting (38.8%), dirtiness (28.5%), and pets (17.2%). Additional research is needed to clarify inter-relationships among these factors and identify strategies for addressing each as part of a comprehensive infection control program in HHC.

Incidence and Prevalence of Infectious Diseases and Their Risk Factors among Patients Who Use Visiting Nursing Services in Japan

This study aimed to clarify the incidence of infectious diseases and the associated risk factors among patients who use visiting nursing services in Japan. We conducted a one-year follow up cohort study with 419 participants. The incidence and period prevalence rate of infectious diseases were 0.63 and 15.0%, respectively. In the multiple logistic regression analysis, the presence of chronic respiratory failure, Parkinson's disease, dermatosis other than pressure ulcers, and the inability to perform oral self-care were significantly related to the contraction of an infectious disease.

The state of infection prevention and control at home health agencies in the United States prior to COVID-19: A cross-sectional study

BACKGROUND

Home health care is a rapidly growing healthcare sector worldwide. Home health professionals face unique challenges related to preventing and controlling infections, which are likely to amplify during an infectious disease outbreak (e.g. SARS-CoV-2). Little is known about the current state of infection prevention and control-related policies and outbreak preparedness at U.S. home health agencies.

OBJECTIVES

In this study, we conducted a national survey to assess infection prevention and control-related policies, infrastructure, and procedures prior to the SARS-CoV-2 pandemic.

DESIGN

Cross-sectional study.

SETTING/PARTICIPANTS

Using a stratified random sample of 1506 U.S. home health agencies, we conducted a 61-item survey (paper and online) from November 9, 2018 to December 31, 2019.

METHODS

Survey data were linked to publicly-available data on the quality of patient care, patient satisfaction, and other agency characteristics. Probability weights were developed to account for sample design and nonresponse; Pearson's χ2, Fisher's exact, t-tests or linear regression were used to compare the universe of agencies/respondents and urban/rural agencies.

RESULTS

35.6% of agencies responded (n = 536). Most home health personnel in charge of infection prevention and control have other responsibilities; one-third have no formal infection prevention and control training. Rural agencies are more likely to not have anyone in charge of infection prevention and control compared to those in urban areas. About 22% of agencies implement recommended guidelines when administering antibiotics. Less than a third (26.4%) report that their staff vaccination rates were higher than 95% during the last flu season. Only 48.1% of agencies accept patients requiring ventilation, and of those, 40.9% located in rural areas do not have specific infection prevention and control policies for ventilated patients, compared to 20.8% in urban areas (p < 0.001). Only 39.7% of agencies provide N95 respirators to their clinical staff; rural agencies are significantly more likely to provide those supplies than urban agencies (50.7% vs. 37.7%, p = 0.004). Lastly, agencies report their greatest challenges with infection prevention and control are collecting/reporting infection data and adherence to/monitoring of nursing bag technique.

CONCLUSIONS

Prior to the SARS-CoV-2 pandemic, we found that infection prevention and control was suboptimal among U.S. home health care agencies. Consequently, most agencies have limited capacity to respond to infectious disease outbreaks. Staff and personal protective equipment shortages remain major concerns, and agencies will need to quickly adjust their existing infection prevention and control policies and potentially create new ones. In the long-term, agencies also need to improve influenza vaccination coverage among their staff. Tweetable abstract: Infection prevention and control infrastructure, policies and procedures and outbreak preparedness at U.S. home health agencies was found to be suboptimal in nationally-representative survey conducted just prior to the COVID-19 pandemic.

"A catalyst for action": Factors for implementing clinical risk prediction models of infection in home care settings

OBJECTIVE

The study sought to outline how a clinical risk prediction model for identifying patients at risk of infection is perceived by home care nurses, and to inform how the output of the model could be integrated into a clinical workflow.

MATERIALS AND METHODS

This was a qualitative study using semi-structured interviews with 50 home care nurses. Interviews explored nurses' perceptions of clinical risk prediction models, their experiences using them in practice, and what elements are important for the implementation of a clinical risk prediction model focusing on infection. Interviews were audio-taped and transcribed, with data evaluated using thematic analysis.

RESULTS

Two themes were derived from the data: (1) informing nursing practice, which outlined how a clinical risk prediction model could inform nurse clinical judgment and be used to modify their care plan interventions, and (2) operationalizing the score, which summarized how the clinical risk prediction model could be incorporated in home care settings.

DISCUSSION

The findings indicate that home care nurses would find a clinical risk prediction model for infection useful, as long as it provided both context around the reasons why a patient was deemed to be at high risk and provided some guidance for action.

CONCLUSIONS

It is important to evaluate the potential feasibility and acceptability of a clinical risk prediction model, to inform the intervention design and implementation strategy. The results of this study can provide guidance for the development of the clinical risk prediction tool as an intervention for integration in home care settings.

A Predictive Risk Model for Infection-Related Hospitalization Among Home Healthcare Patients

Infection prevention is a high priority for home healthcare (HHC), but tools are lacking to identify patients at highest risk of developing infections. The purpose of this study was to develop and test a predictive risk model to identify HHC patients at risk of an infection-related hospitalization or emergency department visit. A nonexperimental study using secondary data was conducted. The Outcome and Assessment Information Set linked with relevant clinical data from 112,788 HHC admissions in 2014 was used for model development (70% of data) and testing (30%). A total of 1,908 patients (1.69%) were hospitalized or received emergency care associated with infection. Stepwise logistic regression models discriminated between individuals with and without infections. Our final model, when classified by highest risk of infection, identified a high portion of those who were hospitalized or received emergent care for an infection while also correctly categorizing 90.5% of patients without infection. The risk model can be used by clinicians to inform care planning. This is the first study to develop a tool for predicting infection risk that can be used to inform how to direct additional infection control intervention resources on high-risk patients, potentially reducing infection-related hospitalizations, emergency department visits, and costs.

Identifying Urinary Tract Infection-Related Information in Home Care Nursing Notes

Objectives:

Urinary tract infection (UTI) is common in home care but not easily captured with standard assessment. This study aimed to examine the value of nursing notes in detecting UTI signs and symptoms in home care.

Design:

The study developed a natural language processing (NLP) algorithm to automatically identify UTI-related information in nursing notes.

Setting and Participants:

Home care visit notes (n = 1,149,586) and care coordination notes (n = 1,461,171) for 89,459 patients treated in the largest nonprofit home care agency in the United States during 2014.

Measures:

We generated 6 categories of UTI-related information from literature and used the Unified Medical Language System (UMLS) to identify a preliminary list of terms. The NLP algorithm was tested on a gold standard set of 300 clinical notes annotated by clinical experts. We used structured Outcome and Assessment Information Set data to extract the frequency of UTI-related emergency department (ED) visits or hospitalizations and explored time-patterns in documentation of UTI-related information.

Results:

The NLP system achieved very good overall performance (F measure = 0.9, 95% CI: 0.87–0.93) based on the test results obtained by using the notes for patients admitted to the ED or hospital due to UTI. UTI-related information was significantly more prevalent (P < .01 for all the tests) in home care episodes with UTI-related ED admission or hospitalization vs the general patient population; 81% of home care episodes with UTI-related hospitalization or ED admission had at least 1 category of UTI-related information vs 21.6% among episodes without UTI-related hospitalization or ED admission. Frequency of UTI-related information documentation increased in advance of UTI-related hospitalization or ED admission, peaking within a few days before the event.

Conclusions and Implications:

Information in nursing notes is often overlooked by stakeholders and not integrated into predictive modeling for decision-making support, but our findings highlight their value in early risk identification and care guidance. Health care administrators should consider using NLP to extract clinical data from nursing notes to improve early detection and treatment, which may lead to quality improvement and cost reduction.

Home Health Staff Perspectives on Infection Prevention and Control: Implications for Coronavirus Disease 2019

Objectives

The role of home healthcare (HHC) services in providing care to vulnerable, often frail individuals with chronic conditions is critical. Effective infection prevention and control (IPC) in HHC is essential to keeping both healthcare workers and patients safe, especially in the event of an emerging infectious disease outbreak. Prior to the coronavirus disease 2019 pandemic, we explored successes and challenges with IPC from the perspectives of HHC staff.

Design

Qualitative descriptive study.

Setting and Participants

From May to November 2018, we conducted in-depth telephone interviews with 41 staff from 13 agencies across the nation.

Methods

Transcripts were coded by a multidisciplinary coding team, and several primary and subcategories were identified using directed content analysis.

Results

Four primary categories were generated including (1) uniqueness of HHC; (2) IPC as a priority; (3) importance of education; and (4) keys to success and innovation. Participants perceived that IPC plays a big part in patient safety and reducing rehospitalizations, and protection of patients and staff was a major motivator for compliance with IPC. The identified challenges included the unpredictability of the home environment, patient/family dynamics, the intermittent nature of HHC, and staffing issues. Education was seen as a tool to improve staff, patient, caregiver and families' compliance with IPC. Keys to success and innovation included a leadership focus on quality, using agency infection data to improve quality, and a coordinated approach to patient care.

Conclusions and Implications

This qualitative work identified barriers to effective IPC in HHC, as well as important facilitators that HHC agencies can use to implement policies and procedures to improve patient care and keep staff safe. Leadership prioritization of IPC is key to implementing appropriate IPC policies and may be especially important in midst of a crisis such as coronavirus disease 2019.

Reaching consensus on a home infusion central line-associated bloodstream infection surveillance definition via a modified Delphi approach

BACKGROUND

A consensus on a central line-associated bloodstream infection (CLABSI) surveillance definition in home infusion is needed to standardize measurement and benchmark CLABSI to provide data to drive improvement initiatives METHODS: Experts across fields including home infusion therapy, infectious diseases, and healthcare epidemiology convened to perform a 3-step modified Delphi approach to obtain input and achieve consensus on a candidate home infusion CLABSI definition.

RESULTS

The numerator criterion was identified by participants as involving one of the 2 following: (1) recognized pathogen isolated from blood culture and pathogen is not related to infection at another site, or (2) one of the following signs or symptoms: fever of 38°C (100.4°F), chills, or hypotension (systolic blood pressure ≤90 mm Hg), and one of the 2 following: (A) common skin contaminant isolated from 2 blood cultures drawn on separate occasions and organism is not related to infection at another site, or (B) common skin contaminant isolated from blood culture from patient with intravascular access device and provider institutes appropriate antimicrobial therapy. The criteria for a denominator included days from the day of admission with a central venous catheter to day of removal of central venous catheter. In addition, 11 inclusion criteria and 4 exclusion criteria were included.

DISCUSSION

Home infusion therapy and healthcare epidemiology experts developed candidate criteria for a home infusion CLABSI surveillance definition.

CONCLUSIONS

Home care and home infusion agencies can use this definition to monitor their own CLABSI rates and implement preventative strategies.

Risk factors for infection in home health care: Analysis of national Outcome and Assessment Information Set data

Patients in home health care (HHC), a rapidly growing healthcare sector, are at high risk for infections. This study aimed to identify risk factors for infections among HHC patients using the Outcome and Assessment Information Set (OASIS) data. We used a 5% random sample of the 2013 national OASIS data. Infections were identified if records indicated that patients were hospitalized or received emergency care for one of three types of infections (respiratory, wound site, and urinary tract infection). Multivariate logistic regression models were used to identify risk factors for each individual infection type. The final analysis included 128,163 patients from 8,255 HHC agencies nationwide. Approximately 3.2% of the patients developed infections during their HHC stay that led to hospitalization or emergency care treatment. We found that associations between demographics and infection risk are specific to the type of infection. In general, a history of multiple hospitalizations in past 6 months, comorbidity, having a severe condition at HHC admission, and impaired physical functioning increased HHC patients' risk of infections. We also identified that HHC patients with caregivers who needed training in providing medical procedure or treatment are at higher risk for wound-site infections. Our findings suggest that patients with underlying medical conditions and limited physical function status are more likely to develop infection. The caregiver's lack of training in providing needed care at home also places HHC patients at high risk for infection. Education for patients and caregivers should be tailored based on their health literacy level to ensure complete understanding.

Home care nurses' identification of patients at risk of infection and their risk mitigation strategies: A qualitative interview study

BACKGROUND

There is an increase in the number of individuals who receive care at home. A significant proportion of these patients acquire infections during their care episode. Whilst there has been significant focus on strategies for infection prevention and control in acute care environments, there is a lack of research into infection prevention in a home care setting.

OBJECTIVES

To understand (1) if and how home care nurses identify patients at high risk of infection and (2) the strategies they use to mitigate that risk.

DESIGN

A qualitative descriptive study, using semi-structured interviews.

SETTING

A large not for profit home care agency located in the New York region of the United States.

PARTICIPANTS

Fifty nurses with a range of experience in home care nursing.

METHODS

Purposive and snowball sampling was used to recruit nurses from across the home care agency with varied years of work experience. Interviews were audio recorded and transcribed. The interviews explored how home care nurses evaluate their patients' risk of developing an infection and if/how they modify the plan of care based on that risk. Data were analysed using thematic analysis.

RESULTS

Three themes were derived from the data; assessing a patient's risk of infection, the risk assessment process, and strategies for mitigating infection risk. Factors identified by nurses as putting a patient at higher risk of infection included being older, having diabetes, inadequate nutrition; along with inadequate clinical information available at start of care. The patient's knowledge and understanding of infection prevention, and the availability and knowledge of caregivers were also important, as was the cleanliness of the home environment. Given the context of home care, where nurses have little control over the environment and care processes in-between visits, the main strategy for infection prevention was patient and caregiver education. Nurses also discussed the importance of their own infection prevention behaviours, and the ability to adjust a patient's plan of care according to their infection risk.

CONCLUSIONS

The study highlights the complexity of the risk assessment process in relation to infection. Existing guidelines for infection prevention and control do not adequately cover the home care environment and more research needs to determine which interventions (such as patient/caregiver education) would be most effective to prevent infections in the home care setting.

Role of Post-Acute Care in Readmissions for Preexisting Healthcare-Associated Infections

OBJECTIVES

Although preventable, healthcare-associated infections (HAIs) are commonly observed in post-acute care settings for at-risk older adults and are a leading cause of hospital readmissions. However, whether HAIs resulting in avoidable readmissions for preexisting HAIs (the same HAI as at the index admission) are more common for patients discharged to post-acute care as opposed to home is unknown. We examined the risk of preexisting HAI readmissions according to patient discharge disposition and comorbidity level.

DESIGN

We used 2013-2014 national hospital discharge data to estimate the likelihood of readmissions for preexisting HAIs according to patients' discharge disposition and whether the likelihood varies according to patient comorbidity level, across four common types of HAIs (not including respiratory infections).

PARTICIPANTS

A total of 702 304 hospital discharges for Medicare beneficiaries 65 years or older.

MEASUREMENTS

Our outcome was a 30-day preexisting, or "linked," HAI readmission (readmission involving the same HAI diagnosis as at the index admission). Patient discharge disposition was skilled nursing facility (SNF), home health care, and home care without home health care ("home").

RESULTS

Of 702 304 index admissions involving HAI treatment, 353 073 (50%) were discharged to a SNF, 179 490 (26%) to home health care, and 169 872 (24%) to home. Overall, 17 523 (2.5%) of preexisting HAIs resulted in linked HAI readmissions, which were more common for Clostridioides difficile infections (4.0%) and urinary tract infections (2.4%) than surgical site infections (1.1%; P < .001). Being discharged to a SNF compared to home or to home health care was associated with a 1.15 percentage point (95% confidence interval = -1.29 to -1.00), or 38%, lower risk of a linked HAI readmission. This risk difference was observed to increase with greater patient comorbidity.

CONCLUSIONS

SNF discharges were associated with fewer avoidable readmissions for preexisting HAIs compared with home discharges. Further research to identify modifiable mechanisms that improve posthospital infection care at home is needed. J Am Geriatr Soc 68:370-378, 2020.

Factors associated with hospitalization for community-acquired pneumonia in home health care patients in Taiwan

BACKGROUND

Pneumonia is a leading cause of hospitalization and death worldwide. However, studies focusing on risk factors of community-acquired pneumonia (CAP) in the home health care (HHC) population remain scarce.

AIMS

This study aimed to evaluate risk factors associated with hospitalization for CAP among HHC patients in Taiwan.

METHODS

This retrospective cross-sectional study extracted data from patients' electronic medical records between 1 January 2017 and 31 December 2017. Multiple logistic regression analyses were performed to explore factors associated with hospitalization for CAP.

RESULTS

In total, 598 patients (men/women: 236/362) were included. One hundred ninety-nine patients (33.28%) were hospitalized for pneumonia. Inpatients showed a higher proportion of the following: male sex, functional impairment, hypoalbuminemia, anemia, nasogastric tube use, excessive polypharmacy, stroke, dementia, heart failure, chronic respiratory disease, and chronic liver disease. Furthermore, nasogastric tube use (odds ratio [OR] 3.01, 95% confidence interval [CI] 1.88-4.82), anemia (OR 2.37, 95% CI 1.48-3.80), male sex (OR 2.14, 95% CI 1.43-3.20), chronic respiratory disease (OR 2.09, 95% CI 1.33-3.30), dementia (OR 1.94, 95% CI 1.27-2.97), heart failure (OR 1.69, 95% CI 1.11-2.56), and hypoalbuminemia (OR 1.57, 95% CI 1.03-2.40) significantly increased the risk of hospitalization for CAP.

CONCLUSIONS

Our results revealed risk factors associated with hospitalization for CAP in HHC patients. In addition to chronic diseases, malnutrition is an important risk factor. Caregivers should make prompt assessments and take preventive measures for such patients.

Surveillance of home health central venous catheter care outcomes: Challenges and future directions

BACKGROUND

Limited data are available regarding central venous catheter (CVC)-related complications that occur in home care. A practical out-of-hospital surveillance mechanism is needed.

METHODS

Home health/infusion agencies in 4 states submitted monthly data from January 2011 through March 2015. Data were collected by patient age and included number of patients on service with a CVC, device days, central line-associated bloodstream infection (CLABSI), CVC-occlusions, doses of fibrinolytics administered, and number of patients receiving fibrinolytics.

RESULTS

Ten agencies from 4 states contributed data across the study period. A total of 913 occlusions and 73 CLABSIs occurred during the 51-month surveillance period. The CLABSI rates per 1,000 device days per year across the study surveillance period ranged from 0-0.40 for pediatric and from 0-0.37 for adult patients, whereas occlusion rates per 1,000 device days ranged from 0.26-1.59 for pediatric and from 2.59-33.29 for adult patients. Doses of fibrinolytic agents administered per 1,000 device days ranged from 0.26-1.80 in pediatric and 3.53-33.85 in adult patients.

CONCLUSIONS

Opportunities exist to further expand efforts to quantify the presence of CVCs in home settings to enable improvements with measuring and tracking patient outcomes as they relate to CVC care. Exploration of continued sustainability of surveillance and data validation are warranted to optimize home health/infusion care practices and outcomes.

Measuring Quality in Home Healthcare

BACKGROUND/OBJECTIVES

Improving quality performance in home health is an increasingly high priority. The objective of this study was to examine trends in industry performance over time using three quality measures: a composite quality metric (Q index), an infection prevention measure (vaccination verification), and an outcome measure (hospital avoidance).

DESIGN/SETTING/PARTICIPANTS/MEASURES

We linked Home Health Compare and Provider of Services data from 2012 to 2016, which included 39 211 observations during the 5-year study period and 7670 agencies in 2016. The Q index was developed to allow comparability over time, equally weighting the contributions of each element. After examining summary statistics, we developed three regression models stratified by ownership (for-profit/nonprofit agency) and included two constructs of nurse staffing, in addition to controlling for known confounders.

RESULTS

Most agencies (80.4%) were for-profit agencies. The Q index and vaccination verification improved substantially over time, but there was no change in hospital avoidance. Ownership status was associated with all three measures (P < .001). Registered nurse staffing (relative to licensed practical nurses and home health aides) was associated with higher Q index and vaccination verification (P < .001).

CONCLUSION

The Q index allows for assessment of trends over time in home healthcare. Ownership and nurse staffing are important factors in the quality of care. The overall home care market is driven by for-profit agencies, but their characteristics and outcomes differ from nonprofit agencies. J Am Geriatr Soc 67:1859-1865, 2019.

Incidence and Risk Factors for Urinary Tract Infection in an Elder Home Care Population in Taiwan: A Retrospective Cohort Study

Urinary tract infection (UTI) is a common infection worldwide. Numerous studies have demonstrated risk factors for UTI in facilities and communities. In this study, we aimed to identify risk factors for UTI in home care patients. Patients who received home care for at least three months in 2017 were included. A UTI episode was defined by admission for UTI treatment, and/or a visit to an outpatient department for UTI and receiving antibiotic prescription. A total of 598 patients aged 81.9 years were included. Overall 47% (281) had at least one UTI episode. After analysis, urinary catheter indwelling was the most important risk factor (odds ratio (OR), 3.21). Underlying diseases (coronary artery disease (CAD), chronic kidney disease (CKD), diabetes mellitus (DM)) were related to UTI with OR ranging from 1.46 to 1.79. Higher Alb (albumin) (OR 0.68) and Hb (hemoglobin) (OR 0.91) were inversely related to UTI. Polypharmacy (OR 1.84) and lower Barthel index scores (OR 1.62) were also related to UTI by different degrees. In conclusion, apart from the unmodifiable factors, avoiding prolonged urinary catheter placement, unnecessary prescriptions, and keeping good nutritional status may help to prevent UTI in home care patients.

Factors for compliance with infection control practices in home healthcare: findings from a survey of nurses' knowledge and attitudes toward infection control

BACKGROUND

Infection is a leading cause of hospitalization among home healthcare patients. Nurses play an important role in reducing infection among home healthcare patients by complying with infection control procedures. However, few studies have examined the compliance of home healthcare nurses with infection control practices or the range of sociocultural and organizational factors that may be associated with compliance.

METHODS

This study analyzed survey responses from nurses at 2 large, certified home healthcare agencies (n = 359), to explore levels of compliance with infection control practices and identify associated demographic, knowledge, and attitudinal correlates.

RESULTS

Nurses reported a high level of infection control compliance (mean = 0.89, standard deviation [SD] = 0.16), correct knowledge (mean = 0.85, SD = 0.09), and favorable attitudes (mean = 0.81, SD = 0.14). Multivariate mixed regression analyses revealed significant positive associations of attitudinal scores with reported level of compliance (P < .001). However, knowledge of inflection control practices was not associated with compliance. Older (P < .05) and non-Hispanic black (P < .001) nurses reported higher compliance with infection control practices than younger and white non-Hispanic nurses.

CONCLUSION

These findings suggest that efforts to improve compliance with infection control practices in home healthcare should focus on strategies to alter perceptions about infection risk and other attitudinal factors.

Cleaning and disinfection in home care: A comparison of 2 commercial products with potentially different consequences for respiratory health

BACKGROUND

Home care aides perform personal care and homemaking services in client homes, including cleaning and disinfection (C&D). Although C&D are performed to remove soil and dust, they are increasingly performed for infection prevention. Many C&D products contain respiratory irritants. The objective of this study was to evaluate 2 commercial products for C&D effectiveness on common household surfaces in seniors' homes.

METHODS

Two C&D visits were conducted in 46 seniors' homes. One visit applied a bleach-containing cleaning product and the other applied an environmentally preferable product. Before and after C&D, the study team performed organic soil bioluminometer measurements on surfaces and collected cotton swab and wipe samples for total bacteria count, Staphylococcus aureus, and Clostridium difficile identification.

RESULTS

Both products removed microorganisms from tested surfaces. S aureus was found in 7 households, 1 strain of which was methicillin-resistant. Both products removed S aureus from all surfaces. Bleach-containing products removed somewhat more soil than environmentally preferable products, although results were statistically significant for only 1 surface.

CONCLUSIONS

The study showed similar, not identical, C&D performance for 2 cleaning products with potentially different consequences for respiratory health. Additional research is needed to develop robust recommendations for safe, effective C&D in home care.

Occupational health of home care aides: results of the safe home care survey

OBJECTIVES

In countries with ageing populations, home care (HC) aides are among the fastest growing jobs. There are few quantitative studies of HC occupational safety and health (OSH) conditions. The objectives of this study were to: (1) assess quantitatively the OSH hazards and benefits for a wide range of HC working conditions, and (2) compare OSH experiences of HC aides who are employed via different medical and social services systems in Massachusetts, USA.

METHODS

HC aides were recruited for a survey via agencies that employ aides and schedule their visits with clients, and through a labour union of aides employed directly by clients or their families. The questionnaire included detailed questions about the most recent HC visits, as well as about individual aides' OSH experiences.

RESULTS

The study population included 1249 HC aides (634 agency-employed, 615 client-employed) contributing information on 3484 HC visits. Hazards occurring most frequently related to musculoskeletal strain, exposure to potentially infectious agents and cleaning chemicals for infection prevention and experience of violence. Client-hired and agency-hired aides had similar OSH experiences with a few exceptions, including use of sharps and experience of verbal violence.

CONCLUSIONS

The OSH experience of HC aides is similar to that of aides in institutional healthcare settings. Despite OSH challenges, HC aides enjoy caring for others and the benefits of HC work should be enhanced. Quantification of HC hazards and benefits is useful to prioritise resources for the development of preventive interventions and to provide an evidence base for policy-setting.
