Does synthetic data augmentation improve the performances of machine learning classifiers for identifying health problems in patient-nurse verbal communications in home healthcare settings?

BACKGROUND: Identifying health problems in audio-recorded patient-nurse communication is important to improve outcomes in home healthcare patients who have complex conditions with increased risks of hospital utilization. Training machine learning classifiers for identifying problems requires resource-intensive human annotation. OBJECTIVE: To generate synthetic patient-nurse communication and to automatically annotate for common health problems encountered in home healthcare settings using GPT-4. We also examined whether augmenting real-world patient-nurse communication with synthetic data can improve the performance of machine learning to identify health problems. DESIGN: Secondary data analysis of patient-nurse verbal communication data in home healthcare settings. METHODS: The data were collected from one of the largest home healthcare organizations in the United States. We used 23 audio recordings of patient-nurse communications from 15 patients. The audio recordings were transcribed verbatim and manually annotated for health problems (e.g., circulation, skin, pain) indicated in the Omaha System Classification scheme. Synthetic data of patient-nurse communication were generated using the in-context learning prompting method, enhanced by chain-of-thought prompting to improve the automatic annotation performance. Machine learning classifiers were applied to three training datasets: real-world communication, synthetic communication, and real-world communication augmented by synthetic communication. RESULTS: Average F1 scores improved from 0.62 to 0.63 after training data were augmented with synthetic communication. The largest increase was observed using the XGBoost classifier where F1 scores improved from 0.61 to 0.64 (about 5% improvement). When trained solely on either real-world communication or synthetic communication, the classifiers showed comparable F1 scores of 0.62-0.61, respectively. CONCLUSION: Integrating synthetic data improves machine learning classifiers' ability to identify health problems in home healthcare, with performance comparable to training on real-world data alone, highlighting the potential of synthetic data in healthcare analytics. CLINICAL RELEVANCE: This study demonstrates the clinical relevance of leveraging synthetic patient-nurse communication data to enhance machine learning classifier performances to identify health problems in home healthcare settings, which will contribute to more accurate and efficient problem identification and detection of home healthcare patients with complex health conditions.

Effectiveness of an interdisciplinary home care approach for older adults with chronic conditions: A systematic review and meta-analysis.

The effectiveness of interdisciplinary home healthcare service consisting of at least two or more healthcare providers, such as a nurse, physician and physiotherapist, for community-dwelling older adults remains unclear. This systematic review assesses the effects of interdisciplinary home care on quality of life (QOL) and health outcomes in older adults with chronic conditions using validated tools. Databases were searched using CINAHL Plus with Full Text, PubMed, EMBASE, CENTRAL, PsycINFO, and OpenGrey from inception to January 25, 2021. Eligibility criteria included (i) an interdisciplinary home care approach, (ii) participants aged 65 years and older with chronic conditions, (iii) randomized controlled trials (RCTs), and (iv) original literature in English. The study reviewer's dyad independently screened the literature and assessed the study quality using the Cochrane's Risk of Bias 2 tool. The analysis employed qualitative and quantitative integration and Grading of Recommendations Assessment, Development, and Evaluation. This study included 13 RCTs with 4709 participants. Four RCTs indicated that interdisciplinary home healthcare services reduced hospital admissions during the initial 6 months after the start of home care interventions (risk ratio [RR] = 0.73; 95% confidence interval [CI] = 0.61-0.88; p < 0.001; I2 = 0%). However, evidence certainty was moderate; QOL and mortality showed low certainty; and institutionalization and adherence showed moderate certainty of evidence. This study suggests that the interdisciplinary home care approach reduces hospital admissions but lacks effects on other outcomes. More robust studies are required to evaluate this evidence.

Alone and together: registered nurses' experiences of work satisfaction in municipal home healthcare.

BACKGROUND: The need for advanced home healthcare (HHC) is expected to increase, with registered nurses (RNs) as key figures. Given the difficulties recruiting and retaining RNs in the HHC sector, understanding their work satisfaction is imperative. AIM: This study aimed to explore RNs' experiences of work satisfaction in the municipal HHC. METHODS: Individual interviews were conducted with RNs (n = 8) in four municipalities in Norway. The data were evaluated using qualitative content analysis. RESULTS: Work satisfaction in HHC was organised into one theme 'alone and together' under four categories-the patient, the co-worker, the registered nurse, and the organisation-and 15 subcategories, including patient diversity, supportive co-workers and professional environment, appropriate workload and responsibilities, and provision of preconditions for self-management. CONCLUSIONS: Patients, co-workers, and organisations were identified as crucial areas affecting RNs' work satisfaction in the municipal HHC. Awareness of these areas is essential to promote RNs' work satisfaction. Patients' diversity adds positively to RNs' work satisfaction. Notably, RNs working alone can affect their work satisfaction not only negatively but also positively.

Medical home healthcare services in Taiwan, 2013-2020.

Taiwan has implemented a Medical Home Healthcare (MHHC) policy to provide home healthcare services to residents in need. First was the Ordinary Medical Home Healthcare (OMHHC) program in 1997 and then expanded to Integrated Medical Home Healthcare (IMHHC) in 2016. The OMHHC is provided care for residents with tubes at home or in institutions by physicians and nurses, and the IMHHC include additional professions, such as pharmacists and dentists. This study analyzed the longitudinal data from 2013 to 2020 with respect to overall home health services utilizations, and the type of services, and compared the differences between areas with and without healthcare shortages. Our results showed that the IMHHC program enhanced the accessibility of home healthcare to those in needs, especially those in healthcare shortage areas. However, some services in the IMHHC program may still have low utilization rates. It is necessary to investigate the potential barriers for residents to access those services.

The need for acute assessments in home healthcare - Swedish registered nurses' experiences.

PURPOSE: The study aims to describe Swedish RNs' experiences of acute assessments at home. More patients with complex nursing needs are cared for at home due to an ageing population. Registered nurses (RNs) who work with home healthcare need a broad medical competence and clinical experience alongside adapted decision support systems for maintaining patient safety in acute assessments within home healthcare. METHODS: A content analysis of qualitative survey data from RNs (n = 19) working within home healthcare in Sweden. RESULTS: There were challenges in the acute assessments at home due to a lack of competence since several of the RNs did not have much experience working as an RN in home healthcare. Important information was missing about the patients, such as access to medical records due to organizational challenges and limited access to equipment and materials. The RNs needed support in the form of cooperation with a physician, support from colleagues, and a decision support system. CONCLUSION: To increase the possibility of patient-safe assessments at home, skills development, collegial support, and an adapted decision support system are needed. Collaboration with primary healthcare, on-call physicians, and nursing staff, and having the opportunity to consult with someone also provide security in acute assessments.

Change in the Proportion of Death at Home during the COVID-19 Pandemic and Its Associated Factors in the Municipality Level: A Nationwide Study in Japan.

Introduction: The coronavirus disease 2019 (COVID-19) pandemic may have led to an increase in home deaths due to hospital bed shortage and hospital visitation restrictions. This study aimed to examine changes in the proportion of home deaths before and after the COVID-19 pandemic and identify associated factors. Methods: We used publicly available nationwide data to describe the proportion of home deaths among total deaths from 2015 to 2021. Furthermore, we used municipal-level data to examine the factors associated with the increase in the proportion of home deaths from 2019 to 2021. The dependent variable was the absolute change in the proportion of home deaths from 2019 to 2021. The independent variables included each municipality's 2019 home death percentage, medical and long-term care (LTC) resources divided by the population of older people, population density, and cumulative number of COVID-19 cases. A multivariable linear regression analysis was conducted after the standardization of each variable. Results: The proportions of home deaths in 2015, 2019, and 2021 were 12.7%, 13.6%, and 17.2%, respectively, indicating a sharp increase in home death rate after the COVID-19 pandemic. In the multivariable linear regression analysis that included 1,696 municipalities, conventional home care support clinics and hospitals (HCSCs) (coefficient [95% confidence intervals (CIs)], 0.19 [0.01-0.37]), enhanced HCSCs (0.53 [0.34-0.71]), home-visiting nurses (0.26 [0.06-0.46]), population density (0.44 [0.21-0.67]), and cumulative COVID-19 cases (0.49 [0.27-0.70]) were positively associated with the increase in home deaths, whereas beds of LTC welfare facilities (-0.55 [-0.74--0.37]) and the proportion of home deaths in 2019 (-1.24 [-1.44--1.05]) were negatively associated with the increase. Conclusions: During the COVID-19 pandemic, home deaths significantly increased, particularly in densely populated areas with high cumulative COVID-19 cases. HCSCs, especially enhanced HCSCs, are crucial for meeting the demand for home-based end-of-life care.

Developing integrated person-centered care quality indicators for home health agencies in Shanghai, China: A modified Delphi-analytic hierarchy process study.

OBJECTIVES: To develop person-centered integrated care quality indicators for home health agencies in Shanghai, China. DESIGN: The study combined the Delphi method and the analytic hierarchy process (AHP). MATERIAL AND METHODS: The Delphi consultation questionnaire was distributed to experts in home healthcare in Shanghai, China. A panel of experts with experience in home healthcare in Shanghai, China, was selected. Purposive sampling was used to choose experts. In this study, ten experts were selected from within sub-fields of home healthcare, including nursing, health policy, quality improvement, person-centered care (PCC), and integrated care. RESULTS: The authority coefficient (Cr) in this study was 0.835. The coordination degree of experts' opinions, which is expressed by Kendall coordination coefficient W (a higher value, better coordination of the item), ranged from 0.352 to 0.386 (p < 0.001). The consistency ratio (CR) values for each level were less than 0.1. The quality indicator system included three first-level indicators, 15 second-level indicators, and 56 third-level indicators. CONCLUSIONS: A person-centered integrated care quality indicator system was developed for home health agencies. The findings from this study enable nurses, managers, and policymakers in home and community-based settings to evaluate person-centered integrated care quality using a robust framework. In addition, these indicators can also be used as a standardized tool to guide the development of long-term care services and supports (LTSS) for home-bound elderly.

Home Health Nurses' Perceptions of Caring for Persons With Severe and Persistent Mental Illnesses.

BACKGROUND: Severe and persistent mental illnesses (SPMIs) affect a significant portion of the adult population in the United States. Despite their enhanced medical disease burden, individuals with SPMIs often lack access to appropriate medical care. Home health services offer cost-effective options for caring for this population in the comfort of their homes. However, little is known about the perceptions of home health nurses providing care to persons with SPMIs, and how they are adjusting care to persons with SPMIs. AIMS: This study aimed to explore home health nurses' perspectives on caring for persons with SPMIs. METHODS: Using a grounded theory approach, individual semi-structured interviews were conducted with home health and home hospice nurses. The research questions focused on the nurses' experiences, barriers and facilitators to care, and the impact of the home environment on caring for persons with SPMIs. Data analysis followed coding procedures outlined in grounded theory, resulting in the development of an axial coding model. RESULTS/CONCLUSIONS: The findings provide valuable insights into the challenges and opportunities faced by home health nurses when providing care for individuals with SPMIs. The outcomes of this study are intended to contribute to the understanding of current care practices and can guide the allocation of resources to improve care for this vulnerable population, such as incorporating training specific to persons with severe psychiatric illnesses.

Infection prevention practice in home healthcare: a mixed-method study in two Swiss home healthcare organisations.

BACKGROUND: Infection prevention and control (IPC) research has long neglected the home healthcare sector with its unique challenges. This study aimed to gain an understanding of the barriers to the implementation of infection prevention practices relevant to this setting, the related attitudes, perceived relevance and priorities from the home healthcare worker perspective in Switzerland. METHODS: The mixed-method study involved semi-structured interviews (n = 18) and an anonymous web-based survey (n = 144) among nursing assistants and nurses from two home healthcare organizations in northwest Switzerland. Questions in both sub-studies focused on perceived challenges to infection prevention practices, perceived relevance, and related attitudes and mitigation strategies. Using an exploratory-sequential design, survey questions were designed to quantify and complement the findings from the interview study. RESULTS: Healthcare workers in these two organisations felt adequately protected, trained and supported by their organisations regarding IPC (survey agreement rates > 90%). General challenges to IPC in the home environment most agreed on were lack of cleanliness, lack of space, and the priorities of the patient to be respected (survey agreement rates 85.4%, 77.1%, and 70.8%, respectively). Practices and perceived challenges in the case of colonisation with multi-drug resistant organisms (MDRO) and potentially infectious diarrheal or respiratory illnesses varied highly regarding information transfer, use of protective equipment, and use and disinfection practices of multi-use equipment. Challenges to hand hygiene, sharps safety, waste management and decontamination of equipment did not feature as a prominent concern. CONCLUSIONS: This study is the first to characterise the implementation of infection prevention practices and the related challenges in home healthcare in Switzerland. Home healthcare workers describe various challenges related to infection prevention practices as largely manageable in their work routine, and generally show satisfaction with the support provided by their organisations regarding IPC precautions. Key findings regarding challenges amenable to interventions include uncertainty and inconsistency regarding the management of MDRO colonisation and acute illnesses, and gaps in information transfer. Those challenges may benefit from both organisational interventions and further research into the level of precautions that are appropriate to the home healthcare setting.

Length of Stay and Discharge Disposition After Total Hip Arthroplasty: A Large Multicenter Propensity Matched Comparison of Robotic-Assisted and Manual Techniques.

BACKGROUND: Robotic-arm assistance continues to gain popularity in total hip arthroplasty (THA) for its potential to improve component placement accuracy and patient outcomes. Nonetheless, there is limited data on the impact of robotic-assisted THA (RA-THA) on hospital length of stay (LOS) and discharge location. This study thus aimed to compare LOS, discharge location, and readmission rate for propensity-matched cohorts of RA-THA versus manual THA (M-THA). METHODS: A retrospective review of a multi-hospital database was performed to identify patients who underwent THA between January 2016 and December 2021 from surgeons who performed both RA-THA and M-THA at 77 geographically diverse hospitals. The RA-THA and M-THA cohorts were 1-to-1 matched based on patient sex, age, and body mass index, resulting in 8,536 patients per cohort. Insurance type, LOS, same-day discharge, discharge disposition, and 90-day all-cause readmission rate were compared using Mann-Whitney U and Chi-square tests. RESULTS: Average LOS was significantly shorter for RA-THA patients (1.39 ± 0.85 days) than for M-THA patients (1.48 ± 0.91 days, P < .001). Compared to 5.6% of M-THA patients, 5.3% of RA-THA patients underwent same-day discharge (P = .38). There were statistically significant differences in discharge disposition between cohorts, with more RA-THA cases discharged home without home healthcare compared to M-THA (47.9 versus 45.5%, P = .001) and fewer RA-THA cases discharged to a skilled nursing facility compared to M-THA (5.6 versus 6.9%, P = .001). The 90-day all-cause readmission rate for RA-THA cases was 3.0%, compared to 3.4% for M-THA cases (P = .26). CONCLUSIONS: Compared to M-THA, RA-THA had a shorter average LOS, a similar percentage of patients with same-day discharge, fewer patients who had skilled nursing facility discharge, and a similar all-cause 90-day readmission rate. These results may be of interest to surgeons participating in bundled payment programs and engaging in cost savings.

Interprofessional collaboration in the home care setting: perspectives of people receiving home care, relatives, nurses, general practitioners, and therapists-results of a qualitative analysis.

BACKGROUND: About one million people in need of home care in Germany are assisted by 15,400 home care services. Home healthcare is mostly a complex endeavour because interprofessional collaboration is often challenging. This might negatively impact patient safety. The project interprof HOME aims to develop an interprofessional person-centred care concept for people receiving home care in a multistep approach. In one of the work packages we explored how people receiving home care, relatives, nurses, general practitioners, and therapists (physiotherapists, occupational therapists, and speech therapists) perceive collaboration in this setting. METHODS: Semi-structured interviews were conducted with 20 people receiving home care and with 21 relatives. Additionally, we worked with nine monoprofessional focus groups involving nurses of home care services (n = 17), general practitioners (n = 14), and therapists (n = 21). The data were analysed by content analysis. RESULTS: Three main categories evolved: "perception of interprofessional collaboration", "means of communication", and "barriers and facilitators". People receiving home care and relatives often perceive little to no interprofessional collaboration and take over a significant part of the organisational coordination and information exchange. Interprofessional collaboration in steady care situations does exist at times and mostly occurs in coordination tasks. Contact and information exchange are rare, however, interprofessional personal encounters are sporadic, and fixed agreements and permanent contact persons are not standard. These trends increase with the complexity of the healthcare situation. Joint collaborations are often perceived as highly beneficial. Means of communications such as telephone, fax, or e-mail are used differently and are often considered tedious and time-consuming. No interprofessional formal written or electronic documentation system exists. Personal acquaintance and mutual trust are perceived as being beneficial, while a lack of mutual availability, limited time, and inadequate compensation hinder interprofessional collaboration. CONCLUSIONS: Interprofessional collaboration in home care occurs irregularly, and coordination often remains with people receiving home care or relatives. While this individual care set-up may work sufficiently well in low complex care situations, it becomes vulnerable to disruptions with increasing complexity. Close interactions, joint collaboration, and fixed means of communication might improve healthcare at home. The findings were integrated into the development of the person-centred interprofessional care concept interprof HOME. TRIAL REGISTRATION: This study is registered on the International Clinical Trails registry platform ClinicalTrials.gov as NCT05149937 on 03/11/2021.

Adaptation of Caregivers of Individuals on Mechanical Ventilation to Caregiving Role.

Aim: The aim of this study is to investigate the adaptation of caregivers of individuals on mechanical ventilation (MV) at home to their caregiver role. Study design: The phenomenological research method, one of the qualitative research methods, was employed in the study. Materials and methods: The sample consisted of 21 individuals who agreed to participate in the research. Necessary legal permissions were obtained to conduct the study. Results: The data were analyzed according to the Roy adaptation model (RAM). Accordingly, the domains of the RAM were expressed with the following themes: Physiologic domain: The effects of care on the caregiver (reluctance toward self-care, psychological fatigue, insomnia, and limitation of social life); Self-concept domain: Supportive situations (trust in God and spiritual practices) and non-supportive situations (fear of losing and self-blame); Role-function domain: Adaptation of the caregiver role (thinking no one else can give similar care) and maladaptation of the caregiver role (fear of failing to cope with suddenly emerging situations, failing to fulfill roles and responsibilities, and economic inadequacy); Interdependence domain: Receiving support (support of healthcare professionals and support of family members) and lack of support (inadequacy of health services and loneliness). Conclusion: It was concluded that individuals who provided care for patients on MV experienced many difficulties and that these difficulties increased their care burden and made it difficult to adapt to their caregiving roles.

Characteristics of Homebound and Patients with Disability Who Use Home-Based Primary Care in Korea: A Retrospective Study for 2018-2022.

(1) Background and Methods: This study evaluated characteristics of South Korean patients necessitating home-based primary care (HBPC) from 2018 to 2022, distinguishing between homebound individuals with chronic conditions and those with registered disabilities. (2) Result: Among 171 HBPC recipients, 56.1% were homebound, predominantly older with a median age of 81 years (interquartile range (IQR 68.5-86.0)), while 43.9% were disabled, generally younger with a median age of 39 years (IQR, 28-64). Activities of daily living were assessed, revealing a median score of 14 (IQR, 10-19), indicative of high care dependency. The most common conditions among homebound patients were dementia (27.1%) and physical mobility difficulties (21.9%), whereas mental disabilities (53.3%) and mobility issues (36.0%) prevailed in disabled patients. The primary HBPC needs for homebound patients included management of acute medical conditions (27.1%) and sores (17.7%). Conversely, regular health check-ups (46.7%) and management of neuropsychiatric symptoms (26.7%) were prevalent among the disabled group. (3) Conclusion: Notably, over 90% of HBPC patients required assistance with daily activities, highlighting significant differences in the needs and characteristics between older, homebound individuals with multiple comorbidities and younger, disabled patients receiving medical aid. These insights emphasize the necessity to develop customized HBPC programs to adequately cater to the diverse patient needs within South Korea.

Association of Depression, Comorbidities, and Sociodemographic Factors among Home Healthcare Recipients.

OBJECTIVES: More than 15 million individuals receive home health care (HHC) for chronic conditions, which allows them to maintain a level of independence and self-sufficiency. Although poor mental health can negatively impact health outcomes, little research has been done on the mental health of these individuals. METHODS: Utilizing National Health Interview Survey years 2019-2022, we ran a cross-sectional analysis to determine rates of depression among individuals who indicated that they utilized HHC services, based on their sociodemographic statuses and diagnosis, as well as their rate of depression by condition whether they utilized HHC services. RESULTS: HHC recipients were significantly more likely to be depressed if they reported being female, age 55-64, low income, low educational attainment, American Indian/Alaskan Native, Hispanic, or lived in a rural area. HHC recipients were more likely to be depressed than their non-HHC recipient counterparts. CONCLUSIONS: These results underscore the need for integrated mental health care in home health. Further, the financial burden of HHC, which may have an additional impact on stress, emphasizes the need for expanded accessibility of these services. CLINICAL IMPLICATIONS: General practitioners and home health professionals should inquire about mental health concerns of these care recipients, and treat or refer accordingly.

Characterizing changes to older adults' care transition patterns from hospital to home care in the initial year of COVID-19.

BACKGROUND: Skilled home healthcare (HH) provided in-person care to older adults during the COVID-19 pandemic, yet little is known about the pandemic's impact on HH care transition patterns. We investigated pandemic impact on (1) HH service volume; (2) population characteristics; and (3) care transition patterns for older adults receiving HH services after hospital or skilled nursing facility (SNF) discharge. METHODS: Retrospective, cohort, comparative study of recently hospitalized older adults (≥ 65 years) receiving HH services after hospital or SNF discharge at two large HH agencies in Baltimore and New York City (NYC) 1-year pre- and 1-year post-pandemic onset. We used the Outcome and Assessment Information Set (OASIS) and service use records to examine HH utilization, patient characteristics, visit timeliness, medication issues, and 30-day emergency department (ED) visit and rehospitalization. RESULTS: Across sites, admissions to HH declined by 23% in the pandemic's first year. Compared to the year prior, older adults receiving HH services during the first year of the pandemic were more likely to be younger, have worse mental, respiratory, and functional status in some areas, and be assessed by HH providers as having higher risk of rehospitalization. Thirty-day rehospitalization rates were lower during the first year of the pandemic. COVID-positive HH patients had lower odds of 30-day ED visit or rehospitalization. At the NYC site, extended duration between discharge and first HH visit was associated with reduced 30-day ED visit or rehospitalization. CONCLUSIONS: HH patient characteristics and utilization were distinct in Baltimore versus NYC in the initial year of the COVID-19 pandemic. Study findings suggest some older adults who needed HH may not have received it, since the decrease in HH services occurred as SNF use decreased nationally. Findings demonstrate the importance of understanding HH agency responsiveness during public health emergencies to ensure older adults' access to care.

Health economic evaluation of a nurse-assisted online eye screening in home healthcare to reduce avoidable vision impairment (iScreen): study protocol for a cluster randomized controlled trial.

BACKGROUND: Among older people undiagnosed and untreated vision impairment and blindness are common. The leading causes are uncorrected refractive errors and cataracts. Vision problems are associated with a lower quality of life, several health problems, and a higher chance of falling accidents and fractures. To eliminate avoidable vision impairment and blindness, targeted eye screening programs are recommended. Older patients, receiving home healthcare, have not yet been considered as a population at risk who could benefit from eye screening. METHODS: A cluster-randomized controlled trial will be conducted to investigate the cost-effectiveness and cost-utility of online nurse-assisted eye screening in home healthcare, compared to care as usual, in reducing avoidable vision impairment. A healthcare and societal perspective will be used. The study will be performed in collaboration with several home healthcare organizations in the Netherlands. The online eye screening consists of near and distance visual acuity, followed by an Amsler grading test. Measurements in both groups will take place at baseline and after 6 and 12 months of follow-up. A total of 240 participants will be recruited. Older men and women (65 +), who receive home-based nursing and are cognitively able to participate, will be included. The primary outcome will be the change of two lines or more on the Colenbrander-1 M visual acuity chart between baseline and 12-month follow-up. DISCUSSION: An eye screening for populations at risk contributes to the detection of undiagnosed and untreated vision impairment. This may reduce the health-related consequences of vision loss and the high economic burden associated with vision impairment. TRIAL REGISTRATION: ClinicalTrials.gov NCT06058637.

Barriers and facilitators to infection prevention practices in home healthcare: a scoping review and proposed implementation framework.

Infection prevention and control (IPC) research has focused on the hospital setting, neglecting the rapidly expanding home healthcare (HHC) sector. Current infection prevention recommendations do not reflect the challenges specific to the HHC setting. This scoping review considered any original studies reporting on barriers or facilitators to infection prevention practices in the context of HHC. Study characteristics were mapped, and a descriptive content analysis was performed. Based on the findings we propose a framework of eight HHC setting characteristics relevant to infection prevention implementation. 33 studies fulfilled the eligibility criteria. A majority of studies addressed sharps injury or blood and body fluid exposure prevention (N=15) and the majority were conducted in the United States (N=23). Study methodologies employed were surveys (N=18), qualitative (N=11), direct observation (N=7), and one interventional study. The HHC setting characteristics relevant to infection prevention implementation were: the care process in the patient's immediate environment; the need to bring equipment and materials into the home; the provision and financing of equipment and materials; the use of patient space and facilities; the unique position of and the expectations towards HHC providers; working alone with little support; the intermittent nature of care; the attitudes of HHC providers formed by their work circumstances. Interventional studies generating higher-quality evidence for implementation are lacking. Furthermore, implementation of aseptic technique and the decontamination and reprocessing of equipment are poorly studied in the HHC setting and deserve more research interest. The proposed framework may guide future research and implementation work.

Clinician Perception of Likelihood of Death in the Next Year Is Associated With 1-Year Mortality and Hospice Use Among Older Adults Receiving Home Health Care.

Background: Given the complex care needs of older adults receiving home health care (HHC), it is important for HHC clinicians to identify those with limited prognosis who may benefit from a transition to hospice care. Objectives: To assess the association between HHC clinician-identified likelihood of death and (1) 1-year mortality, and (2) hospice use. Methods: Prospective cohort study from the National Health and Aging Trends Study (NHATS) waves 2011-2018, linked to the Outcomes and Assessment Information Set (OASIS) HHC assessment and Medicare data among 915 community-dwelling NHATS respondents. HHC clinician-identified likelihood of death/decline was determined using OASIS item M1034. Multivariable logistic regression was used to assess the association between clinician-identified likelihood of death/decline and 1-year mortality and hospice use. Results: HHC clinicians identified 42% of the sample as at increased risk of decline or death. One year mortality was 22.3% (n = 548), and 15.88% (n = 303) used hospice within 12 months of HHC. HHC clinician-perceived likelihood of death/decline was associated with greater odds of 1-year mortality (odds ratio [OR], 6.57; confidence interval (95% CI), 2.56-16.90) and was associated with greater likelihood of hospice use (OR, 1.61; 95% CI, 1.00-2.62). Conclusion: HHC clinician perception of patients' risk of death or decline is associated with 1-year mortality. A better understanding of HHC patients at high risk for mortality can facilitate improved care planning and identification of homebound older adults who may benefit from hospice.

Prediction Models for Readmission Using Home Healthcare Notes and OMOP-CDM.

This study developed readmission prediction models using Home Healthcare (HHC) documents via natural language processing (NLP). An electronic health record of Ajou University Hospital was used to develop prediction models (A reference model using only structured data, and an NLP-enriched model with structured and unstructured data). Among 573 patients, 63 were readmitted to the hospital. Five topics were extracted from HHC documents and improved the model performance (AUROC 0.740).
