An ambient assisted living architecture for hospital at home coupled with a process-oriented perspective.

The growing number of next-generation applications offers a relevant opportunity for healthcare services, generating an urgent need for architectures for systems integration. Moreover, the huge amount of stored information related to events can be explored by adopting a process-oriented perspective. This paper discusses an Ambient Assisted Living healthcare architecture to manage hospital home-care services. The proposed solution relies on adopting an event manager to integrate sources ranging from personal devices to web-based applications. Data are processed on a federated cloud platform offering computing infrastructure and storage resources to improve scientific research. In a second step, a business process analysis of telehealth and telemedicine applications is considered. An initial study explored the business process flow to capture the main sequences of tasks, activities, events. This step paves the way for the integration of process mining techniques to compliance monitoring in an AAL architecture framework.

Telemedicine-assisted care of an older patient with COVID-19 and dementia: bridging the gap between hospital and home.

Hospital at Home (HaH) has been proposed as a solution to relieve pressure on hospital beds during the COVID-19 pandemic; however, caregivers' feelings of inadequacy and concerns on the need for tighter clinical monitoring might lead to unnecessary and potentially harmful hospital admissions in frail older patients with mild or atypical COVID-19. Here we report the case of a 91-year old woman with severe dementia and atypical COVID-19 that could be successfully managed by our HaH thanks to her highly motivated caregivers and the support of a telemedicine solution (TMS) to provide caregiver training and support as well as supplementary telemonitoring. Despite some well-known issues on TMS use, the hybrid in-person and tele-visit approach of TMS-assisted HaH could help to create a "secure" environment, empowering caregivers to manage frail older adults with COVID-19 at home, avoiding unnecessary admissions to closed wards and their negative physical, functional and psychological outcomes.

A Process Mining Application for the Analysis of Hospital-at-Home Admissions.

This article proposes the analysis of the admissions to hospital-at-home service within the framework of process mining. In addition to conventional modeling in standard languages, relying on interviews and continuous improvement, we propose the adoption of an automatic process discovery technique based on data collected by the hospital information system. We focus on the patient admission process, in which staff discriminate cases of interest for the service. Our methodological framework starts with the extraction of process information from the existing dataset. Once obtained meaningful data for an event log analysis, we propose the adoption of a process discovery algorithm by using a specific tool for process mining. In the context of Business Process Management, we suggest a practical application to be explored in order to improve standard modeling, opening the way to perform business process simulation with scenario analysis.

Home management of hematological patients requiring hospital admission.

The hospital-at-home service (HHS) could be considered as an alternative to the traditional ward for elderly patients. We aimed at evaluating the home management of elderly people requiring transfusions. The ever-increasing demand on acute hospital services requires alternative methods of delivering all aspects of health care. HHS demonstrated to be as efficacious as a traditional ward for elderly and functionally compromised patients. The method was a retrospective descriptive study enrolling patients needing an hospital admission from 1st January 2007 to 31st December 2007 and reporting an hematological discharge's diagnosis as primary or secondary diagnosis. A total of 54 patients were evaluated in this study. Of them, 34 (62.9%) needed a hemocomponent transfusion for a total volume of 112 blood units and 49 platelet pools. Patients requiring at least one blood or platelet transfusion were more functionally compromised and presented a higher level of acute physiology and chronic health evaluation, compared to the non-transfused ones. The conclusion was that hematological subjects mainly the frail ones and functionally highly compromised with acute illnesses could be treated at home as an alternative of the traditional medical ward. This could be the starting point for future studies that will be able to increase the power of hospital-at-home service for this type of patients.

Predictors of treatment failures during chemotherapy: A prospective study on 110 older cancer patients.

Several instruments have been proposed to improve treatment decisions in elderly cancer patients, but evidence of their impact in clinical practice is limited. The aim of this study was to analyze the role of clinical and functional factors in predicting serious adverse events, including death, severe toxicity or treatment interruption, during chemotherapy in elderly cancer patients. The survey evaluated elderly with lung or colon or breast cancer treated with chemotherapy, followed by S. Giovanni Battista Hospital. We enrolled 110 consecutive patients older than 70 years of age with lung (n=45), colon (n=50) and breast (n=15) cancer between October 2004 and October 2005. Overall, 73/110 patients (66.4%) experienced adverse events as death (n=14), grades III and IV toxicity (n=40), or treatment interruption for other reasons (n=19). The variables with stronger predictivity were advanced stage, toxicity of treatment, level of comorbidity and Karnofsky performance status (KPS). instrumental activities of daily living (IADL) index and age itself were not independent predictors. In conclusion our results confirm the need of a careful selection of elderly patients suitable for chemotherapy, giving more weight to comorbidity and KPS scores than to age itself. The potential role of other functional evaluations need to be further assessed in randomized controlled trials.

Predictors of falls and hospitalization outcomes in elderly patients admitted to an acute geriatric unit.

We aimed to identify fall incidence, predictors and characteristics and to investigate hospitalization outcomes for elderly inpatients. In 340 men and 280 women consecutively admitted to a Acute Geriatric Ward of a University Hospital the following variables were evaluated: demographics, clinical history, main disease responsible for hospitalization, comorbidity (cumulative illness rating scale: CIRS 1 and 2) gait and balance deficit (Tinetti's scales), cognition/function (short portable mental status questionnaire: SPMSQ); activities of daily living: ADL; instrumental activities of daily living: IADL; delirium (confusion assessment method: CAM), drugs administered during hospitalization. Overall 80 falls occurred in 70 patients. The incidence rate of falls was of 6.0 per 1000 patient-days with 2.0 falls per bed/year. Age (relative risk=RR=1.050; 95% confidence interval=CI=1.013-1.087), delirium (RR=3.577; 95% CI 1.096-11.672), diabetes (RR=5.913; 95% CI 1.693-20.644), balance deficit (RR=0.914; 95% CI 0.861-0.970) and polypharmacy (RR=1.226; 95% CI 1.122-1.340) were independently predictive of falling. Fallers had a prolonged length of stay (LOS) (35.5+/-47.8 days vs. 23.2+/-27.2; p=0.01) and more frequent nursing home placements (12.9% vs.5.6%; p<0.005). The knowledge of falling predictors might help in planning specific preventive strategies to improve the patients' global health status and to reduce the costs of medical care.

Substitutive "hospital at home" versus inpatient care for elderly patients with exacerbations of chronic obstructive pulmonary disease: a prospective randomized, controlled trial.

OBJECTIVES: To evaluate hospital readmission rates and mortality at 6-month follow-up in selected elderly patients with acute exacerbation of chronic obstructive pulmonary disease (COPD). DESIGN: Prospective randomized, controlled, single-blind trial with 6-month follow-up. SETTING: San Giovanni Battista Hospital of Torino. PARTICIPANTS: One hundred four elderly patients admitted to the hospital for acute exacerbation of COPD were randomly assigned to a general medical ward (GMW, n=52) or to a geriatric home hospitalization service (GHHS, n=52). MEASUREMENTS: Measurements of baseline sociodemographic information; clinical data; functional, cognitive, and nutritional status; depression; and quality of life were obtained. RESULTS: There was a lower incidence of hospital readmissions for GHHS patients than for GMW patients at 6-month follow-up (42% vs 87%, P<.001). Cumulative mortality at 6 months was 20.2% in the total sample, without significant differences between the two study groups. Patients managed in the GHHS had a longer mean length of stay than those cared for in the GMW (15.5+/-9.5 vs 11.0+/-7.9 days, P=.010). Only GHHS patients experienced improvements in depression and quality-of-life scores. On a cost per patient per day basis, GHHS costs were lower than costs in GMW ($101.4+/-61.3 vs $151.7+/-96.4, P=.002). CONCLUSION: Physician-led substitutive hospital-at-home care as an alternative to inpatient care for elderly patients with acute exacerbations of COPD is associated with a substantial reduction in the risk of hospital readmission at 6 months, lower healthcare costs, and better quality of life.

Relationship between Prostatic Specific Antigen (PSA) and volume of the prostate in the Benign Prostatic Hyperplasia in the elderly.

Increase of the Prostatic Specific Antigen (PSA) is a non-invasive, sensitive and specific markers for prostatic diseases, including prostatic cancer. However, age-related Benign Prostatic Hyperplasia (BPH), as well as prostatitis, may at the same time alter PSA values. The aim of this study was to evaluate the relationship between ageing and PSA, and whether age-specific upper normal limits of PSA should be considered for elderly patients. We evaluated 569 consecutive subjects aged 60 years or more (mean age 74.2 years) who were free from malignant prostatic disease, without clinical evidence of prostatic phlogosis and who were not receiving PSA levels affecting drugs. All patients underwent Digital Rectal Examination (DRE) and Trans-Rectal Ultrasonography (TRU), with determination of the three prostatic diameters, the Maximum Adenoma Diameter (MAD) and calculation of the prostatic volume (PV) by the ellipsoid formula. PSA was determined in all patients before DRE and TRU, and the PSA free ratio was determined in those with total PSA values >4 ng/ml. The PSA density was calculated according to the formula PSA/PV. One hundred and seventy-nine subjects (31.6%) were found to have PSA values >4 ng/ml: among them, 26 (14.5%) had values exceeding 10 ng/ml. Age was slightly correlated with PV (P<0.05), but not with PSA values. On the contrary, PSA values were strongly related with PV and MAD (P<0.01 both). Mean PSA-free ratio was 16.3+/-6.0% and most of patients had values in the so-called 'grey zone' of discrimination between benignity and malignity. Elevated PSA levels are common in older subjects without evidence of prostatic malignancy; PSA values are poorly affected by age itself and strongly correlated with increasing PV. These results suggest the possibility to consider as indicative of benignity PSA values between 4 and 10 ng/ml, when these values are associated with relevant increase of PV and with PSA-free ratio greater than 10%.
