Evaluation of a training program for emergency medical service physician dispatchers to reduce emergency departments visits

Background

Emergency Departments (ED) have seen an increasing number of older patients who are mostly referred following a call to the Emergency Medical Services (EMS). Long waiting times in settings, which are not designed to meet older patients' needs, may increase the risk of hospital-acquired complications. Unnecessary visits should therefore be avoided as much as possible. The objective of the study was to evaluate whether a program to provide geriatric knowledge and tools to the dispatching physicians of the EMS could decrease ED referrals of older patients.

Methods

Design: Before-and-after study with two 6-month periods before and after intervention. Participants: All calls received by a dispatching physician of the Rhône EMS from 8 am to 6 pm concerning patients aged 75 years or above during the study period. Intervention: A program consisting of training dispatching physicians in the specific care of older patients and the developing, with a multidisciplinary team, of specific tools for dispatching physicians. Outcome: Proportion of ED referrals of patients aged 75 years or above after a call to the EMS.

Results

A total of 2671 calls to the Rhône EMS were included corresponding to 1307 and 1364 patients in the pre-and post-intervention phases, respectively. There was no significant difference in the proportion of referrals to the ED between the pre-intervention (61.7%) and the post-intervention (62.8%) phases (p = 0.57). Contact of the patients with their General Practitioner (GP) in the month preceding the call was associated with a 22% reduced probability of being referred to an ED.

Conclusions

No beneficial effect of the intervention was demonstrated. This strategy of intervention is probably not effective enough in such time-constraint environment. Other strategies with a specific parallel dispatching of geriatric calls by geriatricians should be tested to avoid these unnecessary ED referrals.

Emergency hospitalization in the elderly in a French university hospital: medical and social conditions and crisis factors precipitating admissions and outcome at discharge

Emergency admissions of elderly patients constitute a major management issue due to the complexity of their problems. The aim of this retrospective observational study was to identify medical and social characteristics and crisis factors for emergency department (ED) hospitalization in elderly patients, and to evaluate the influence of these factors on the length of stay and outcome at discharge. During a 4-month period, 396 patients aged 70 years and older were referred to the ED of a University Hospital (H?pital Edouard Herriot) in Lyon, France. A questionnaire specifically designed for the study was completed for each patient using the information in the patients' files previously filled in by the "Rapid Geriatric Assessment Team" of the ED. We described civil and marital status, living conditions, reason for admission to ED and other associated pathologies according to the ICM-9, crisis factors, length of stay (LOS) and outcome at discharge. The mean age was 81.9 years (SD 6.5); two thirds (66.7%) of the study subjects were female, and 46.7% were widowed; the majority (68.7%) lived in their own homes. The main reasons for admission were cardiopulmonary diseases in 31.6% of cases, followed by neuropsychiatric disorders in 28.2%, and falls in 8.3%; a final category (31.8%) included subjects admitted for general, non-specific symptoms. Among the crisis factors observed, 49.4% presented an acute episode of a chronic illness, 33.6% lived alone, and 20.9% had been hospitalized during the 6-month period preceding the study. The average LOS was 3.15 days. The multivariate model showed that falls increase LOS by 74%, dementia by 65%, and depression by 21%. Upon discharge, 13% returned to their residence before hospitalization, 55% were transferred to a medical speciality ward, and 4% to other facilities, whereas only 19% were transferred to a geriatric ward, and 9% died during their stay in the ED. The multinomial model showed that outcome at discharge was influenced by functional dependency, dementia, depression, and acute episodes of a chronic illness. For many elderly, the ED remains a critical point of access to more complete managed care. This elderly population is comprised of polypathological, frail persons whose morbid state requires multidisciplinary management in geriatric units. The findings of this study suggest that interventions of multidisciplinary networks, such as home health care programs aimed at detecting crisis factors and establishing early prevention of crisis states, may improve unfavorable medical and social conditions and reduce hospitalization in geriatric patients.     

Call Center Remote Triage by Nurse Practitioners Was Associated With Fewer Subsequent Face-to-Face Healthcare Visits

BackgroundIn 2015, the Veterans Health Administration (VHA) incorporated nurse practitioners (NPs) into remote triage call centers to supplement registered nurse (RN)–handled calls.ObjectiveTo assess 7-day healthcare use following telephone triage by NPs compared to RNs. We hypothesized that NP clinical decision ability may reduce follow-up healthcare.DesignRetrospective observational comparative effectiveness study of clinical and administrative databases. NP routed calls were matched to RN calls based on chief complaint with propensity score matching and multivariate count data models, adjusting for differences in call severity and patient comorbidity.ParticipantsCallers to a VHA regional call center, April 2015 to March 2019.Main MeasuresPrimary care, specialty care, and emergency department (ED) visits plus hospitalizations within 7 days.Key ResultsNP-handled calls (N = 1554) were matched to RN calls (N = 48,024) for the same chief complaint. NP-handled calls, compared to RNs, had lower comorbidities, fewer hospitalizations, and less urgent complaints. Seven-day healthcare use was lower for NP compared to RN calls for specialty care (0.15 vs. 0.20 visits per person [VPP]; p < 0.001), ED (0.11 vs. 0.27 VPP; p < 0.001), and hospitalizations (0.01 vs. 0.04 VPP; p < 0.001), but not primary care (0.43 vs. 0.42 VPP; p = 0.80). In adjusted analyses, estimated avoided in-person visits per 100 calls routed to NPs were 0.7 primary care visits (95% confidence interval [CI] 0.4, 1.0), 2.6 specialty care visits (95% CI 0.0, 5.1), 5.9 ED visits (95% CI 2.7, 9.1), and 1.4 hospital stays (95% CI 0.1, 2.6). Propensity score–matched models comparing NP (N = 1533) to RN (N = 2646) calls had adjusted odds ratios for 7-day healthcare use of 0.75 (primary care), 0.75 (specialty care), and 0.73 (ED) (all p < 0.003).ConclusionIncorporating NPs into a call center was associated with lower in-person healthcare use in the subsequent 7 days compared to routine RN-triaged calls.KEY WORDS: after-hours care, telephone triage, call center, telephone medicine     

The establishment of geriatric intervention group and geriatric assessment at emergency of Henri-Mondor hospital

BACKGROUND: The official French demographic previsions are a growing number of the older than 75 years elderly people. The Emergency services face this demographic evolution. We describe the establishment of the geriatric intervention group at the emergency of the Henri-Mondor university hospital at Creteil (France) and analyse the results of the geriatric assessment at the short unit care during the first four months. METHODS: We analysed the results of the geriatric assessment of 206 patients during the first four months, by considering the final unit care. The geriatric assessment evaluates functional abilities, cognitive status and thymic function with elderly people validated tests and subjective assessment of nutrition status and the sensorial functions. RESULTS: The statistical analysis of the geriatric assessment results was significant among the different hospitalized groups of patients, for the cognitive status, the nutritional risk and the walk and standing evaluation. CONCLUSION: The results of the geriatric assessment at emergency showed cognitive impairment and gait abnormality in elderly patients were at risk of hospitalization.     

Comprehensive geriatric assessment in the emergency department for the prediction of readmission among older patients: A 3-month follow-up study

BackgroundOlder people present to the emergency department (ED) with distinct patterns and emergency care needs. This study aimed to use comprehensive geriatric assessment (CGA) surveying the patterns of ED visits among older patients and determine frailty associated with the risk of revisits/readmission.MethodsThis prospective study screened 2270 patients aged ≥75 years in the ED from August 2018 to February 2019. All patients underwent CGA. A 3-months follow-up was conducted to observe the hospital courses of admission and revisit/readmission.ResultsA total of 270 older patients were enrolled. The independent predictors of admission at initial ED visit were the risk of nutritional deficit and instrumental activities of daily living (IADL). In the admission group, the independent predictors of revisit/readmission were a fall in the past year and mobility difficulties. In the discharge group, the independent predictors of revisit/readmission were frailty and insomnia. Regardless if older patients were either admitted or discharged at the initial ED visit, the independent predictor of revisit/readmission for older patients was frailty.ConclusionOur study showed that frailty was the only independent predictor for revisit/readmission after ED discharge during the 3-month follow up. For ED physicians, malnutrition and IADL were independent predictors in recognizing whether the older patient should be admitted to the hospital. For discharged older ED patients, frailty was the independent predictor for the integration of community services for older patients to decrease the rate of revisit/readmission in 3 months.     

Home FIRsT: interdisciplinary geriatric assessment and disposition outcomes in the Emergency Department

BackgroundOlder people in the Emergency Department (ED) are clinically heterogenous and some presentations may be better suited to alternative out-of-hospital pathways. A new interdisciplinary comprehensive geriatric assessment (CGA) team (Home FIRsT) was embedded in our acute hospital's ED in 2017.AimTo evaluate if routinely collected CGA metrics were associated with ED disposition outcomes.DesignRetrospective observational study.MethodsWe included all first patients seen by Home FIRsT between 7^th May and 19^th October 2018. Collected measures were sociodemographic, baseline frailty (Clinical Frailty Scale), major diagnostic categories, illness acuity (Manchester Triage Score) and cognitive impairment/delirium (4AT). Multivariate binary logistic regression models were computed to predict ED disposition outcomes: hospital admission; discharge to GP and/or community services; discharge to specialist geriatric outpatients; discharge to the Geriatric Day Hospital.ResultsIn the study period, there were 1,045 Home FIRsT assessments (mean age 80.1 years). For hospital admission, strong independent predictors were acute illness severity (OR 2.01, 95% CI 1.50-2.70, P<0.001) and 4AT (OR 1.26, 95% CI 1.13 – 1.42, P<0.001). Discharge to specialist outpatients (e.g. falls/bone health) was predicted by musculoskeletal/injuries/trauma presentations (OR 6.45, 95% CI 1.52 – 27.32, P=0.011). Discharge to the Geriatric Day Hospital was only predicted by frailty (OR 1.52, 95% CI 1.17 – 1.97, P=0.002). Age and sex were not predictive in any of the models.ConclusionsRoutinely collected CGA metrics are useful to predict ED disposition. The ability of baseline frailty to predict ED outcomes needs to be considered together with acute illness severity and delirium.     

Emergency Department Visits Versus Hospital Readmissions Among Patients Hospitalized for Heart Failure

BackgroundWorsening heart failure (HF) often requires hospitalization but in some cases may be managed in the outpatient or emergency department (ED) settings. The predictors and clinical significance of ED visits without admission vs hospitalization are unclear.MethodsThe ASCEND-HF trial included 2661 US patients hospitalized for HF with reduced or preserved ejection fraction. Clinical characteristics were compared between patients with a subsequent all-cause ED visit (with ED discharge) within 30 days vs all-cause readmission within 30 days. Factors associated with each type of care were assessed in multivariable models. Multivariable models landmarked at 30 days evaluated associations between each type of care and subsequent 150-day mortality.ResultsThrough 30-day follow-up, 193 patients (7%) had ED discharge, 459 (17%) had readmission, and 2009 (76%) had neither urgent visit. Patients with ED discharge vs readmission were similar with respect to age, sex, systolic blood pressure, ejection fraction, and coronary artery disease, whereas ED discharge patients had a modestly lower creatinine (P < .01). Among patients with either event within 30 days, a higher creatinine and prior HF hospitalization were associated with a higher likelihood of readmission, as compared with ED discharge (P < .02). Landmarked at 30 days, rates of death during the subsequent 150 days were 21.0% for patients who were readmitted and 11.4% for patients discharged from the ED. Compared with patients who were readmitted, ED discharge was independently associated with lower 150-day mortality (adjusted hazard ratio 0.58, 95% confidence interval 0.36–0.92, P = .02).ConclusionsIn this cohort of US patients hospitalized for HF, worse renal function and prior HF hospitalization were associated with a higher likelihood of early postdischarge readmission, as compared with ED discharge. Although subsequent mortality was high after discharge from the ED, this risk of mortality was significantly lower than patients who were readmitted to the hospital.     

A Geriatric Emergency Service for Acutely Ill Elderly Patients: Pattern of Use and Comparison with a Conventional Emergency Department in Italy

The current disease‐oriented, episodic model of emergency care does not adequately address the complex needs of older adults presenting to emergency departments (EDs). Dedicated ED facilities with a specific organization (e.g., geriatric EDs (GEDs)) have been advocated. One of the few GED experiences in the world is described and its outcomes compared with those of a conventional ED (CED). In a secondary analysis of a prospective observational cohort of 200 acutely ill elderly patients presenting to two urban EDs in Ancona, Italy, identifiers and triage, clinical, and social data were collected and the following outcomes considered: early (30‐day) and late (6‐month) ED revisit, frequent ED return, hospital admission, and functional decline. Death, functional decline, any ED revisit and any hospital admission were also considered as a composite outcome. Odds ratios and 95% confidence intervals (CIs) were calculated. Overall, GED patients were older and frailer than CED patients. The two EDs did not differ in terms of early, late, or frequent ED return or in 6‐month hospital admission or functional decline. The mortality rate was slightly but significantly lower in the GED patients (hazard ratio=0.47, 95% CI=0.22–0.99, P=.047). The data suggest noninferiority and, indirectly, a slight superiority for the GED system in the acute care of elderly people, supporting the hypothesis that ED facilities specially designed for older adults may provide better care.     

Faible taux de couverture vaccinale contre la grippe des sujets âgés hospitalisés en France

PurposeAnnual influenza epidemics is still a major cause of illness and mortality especially in the elderly. Annual vaccination is the most effective way to prevent disease and reduce hospitalizations and deaths related to influenza in the elderly population. In France, there are few data available about vaccination coverage of elderly at risk for influenza. The aim of the study was to measure the influenza vaccination coverage and assess traceability in the elderly (≥ 75 years old) admitted to hospital.MethodsIn participating French hospitals, each patient aged 75 years or more, hospitalized in acute units of internal medicine, geriatric and infectious disease, was included in a multicentric point prevalence survey.ResultsBetween April and May 2011, 63 departments of 28 hospitals participated and 903 patients were included (mean age of included patients: 85 years): 82% were previously living at home and 13% were institutionalized. Most of them had multiple diseases (77%) and 21% were admitted for a respiratory disease: 58% were vaccinated against influenza. A back-up for traceability was identified in 53% of cases. Patient refusal may be a common determinant of non-vaccination, as well as non-proposal by the attending physician. The vaccination rate did not differ according to usual living place including accommodation facilities in geriatric.ConclusionCoverage for influenza vaccination is low in hospitalized elderly patients and traceability is insufficient. This vaccine, noncompliance mostly linked to the refusal of patients, is a worrisome public health problem, on which physicians and hospital staff in charge, as well as institutions, should turn attention toward a multi-professional preventive strategy against the morbidity risk of this infectious disease.     

Functional recovery of elderly patients hospitalized in geriatric and general medicine units. The PROgetto DImissioni in GEriatria Study

OBJECTIVES: To investigate the characteristics of patients who regain function during hospitalization and the differences in terms of functional outcomes between patients admitted to geriatric and general medicine units. DESIGN: Multicenter, prospective cohort study. SETTING: Acute care geriatric and medical wards of five Italian hospitals. PARTICIPANTS: One thousand forty‐eight elderly patients hospitalized for acute medical diseases. MEASUREMENTS: Functional status 2 weeks before hospital admission (baseline), at admission, and at discharge, as measured using the Barthel Index (BI). RESULTS: Geriatric patients were older (P<.001) and had lower preadmission functional levels (P<.001) than medical patients. Between baseline and discharge, 43.2% of geriatric and 18.9% of medical patients declined in physical function. In the subpopulation of 464 patients who had declined before hospitalization (between baseline and admission), 59% improved during hospitalization (45% of geriatric and 75% of medical patients), whereas only approximately 1% declined further. High baseline function (odds ratio (OR)=1.03, 95% confidence interval (CI)=1.02–1.04, per point of BI) and greater functional decline before hospitalization (OR 0.95, 95% CI 0.94–0.97, per % point of BI decline) were significant predictors of in‐hospital functional improvement; type of hospital ward and age were not. CONCLUSION: Although geriatric patients have overall worse functional outcomes, in‐hospital functional recovery may be frequent even in geriatric units, particularly in patients with greater preadmission functional loss and high baseline level of function.     

A randomized trial of comprehensive geriatric assessment and home intervention in the care of hospitalized patients

OBJECTIVE: to prove the effectiveness of geriatric evaluation and management for elderly, hospitalized patients, combined with post-discharge home intervention by an interdisciplinary team. DESIGN: randomized controlled trial with outcome and costs assessed for 12 months after the date of admission. SETTING: university-affiliated geriatric hospital and the homes of elderly patients. SUBJECTS: 545 patients with acute illnesses admitted from home to the geriatric hospital. INTERVENTIONS: patients were randomly assigned to receive either comprehensive geriatric assessment and post-discharge home intervention (intervention), comprehensive geriatric assessment alone (assessment) or usual care. MAIN OUTCOME MEASURES: survival, functional status, rehospitalization, nursing home placement and direct costs over 12 months. RESULTS: the intervention group showed a significant reduction in length of hospital stay (33.49 days vs 40.7 days in the assessment group and 42.7 days in the control group; P < 0.05) and rate of immediate nursing home placement (4.4% vs 7.3% and 8.1%; P < 0.05). There was no difference in survival, acute care hospital readmissions or new admissions to nursing homes but the intervention group had significantly shorter hospital readmissions (22.2 days vs 34.2 days and 35.7 days; P < 0.05) and nursing home placements (114.7 days vs 161.6 days and 170.0 days; P < 0.05). Direct costs were lower in the intervention group [about DM 7000 (US $4000) per person per year]. Functional capacities were significantly better in the intervention group. CONCLUSIONS: comprehensive geriatric assessment in combination with post-discharge home intervention does not improve survival, but does improve functional status and can reduce the length of the initial hospital stay and of subsequent readmissions. It can reduce the rate of immediate nursing home admissions and delay permanent nursing home placement. It may also substantially reduce direct costs of hospitalized patients.     

Prediction of falls in rehabilitation and acute care geriatric setting

PurposeTo examine the feasibility to develop an efficient and applicable geriatric hospital-specific fall risk-prediction tool.Patients and methodsThis is a prospective cohort study in five rehabilitation units and one acute care geriatric unit at a geriatric hospital. In total, 1013 patients aged over 65 years were admitted during a 6-month period. Fourteen patient characteristics found in previous studies to be risk factors for falls were tested for predictive validity. The characteristics included: age, gender, history of falls, dementia, delirium, use of psychoactive drugs, using a wheelchair, acute illness, state of post joint arthroplasty, Parkinson's disease, stroke, heart disease, vision disturbance, and hospitalization for deconditioning. Each of the characteristics was assessed individually for their predictive power based on logistic regression models.ResultsDementia (p < 0.001) and delirium (p = 0.005) predicted falls in patients hospitalized for rehabilitation. In the multivariate model, only dementia was a significant predictor in these patients, (p = 0.014), while delirium only approached significance. Being hospitalized for rehabilitation after arthroplasty was a negative predictive factor of falls (p = 0.022). Among acute care patients, only being operated on in the past for joint arthroplasty (p = 0.035) predicted falls in the multivariate model, while using a wheelchair was a negative predictive factor (p = 0.023).ConclusionThe current study reveals a poor predictive value for falls for most patient characteristics (except delirium and dementia) in elderly hospitalized patients, illustrating the incertitude of developing and using predictive falls tools based on such characteristics in hospitalized elderly patients.     

Prognostic value of early warning scores in the emergency department (ED) and acute medical unit (AMU): A narrative review

BackgroundA wide array of early warning scores (EWS) have been developed and are used in different settings to detect which patients are at risk of deterioration. The aim of this review is to provide an overview of studies conducted on the value of EWS on predicting intensive care (ICU) admission and mortality in the emergency department (ED) and acute medical unit (AMU).MethodsA literature search was conducted in the bibliographic databases PubMed and EMBASE, from inception to April 2017. Two reviewers independently screened all potentially relevant titles and abstracts for eligibility.Results42 studies were included. 36 studies reported on mortality as an endpoint, 13 reported ICU admission and 9 reported the composite outcome of mortality and ICU admission. For mortality prediction National Early Warning Score (NEWS) was the most accurate score in the general ED population and in those with respiratory distress, Mortality in Emergency Department Sepsis score (MEDS) had the best accuracy in patients with an infection or sepsis. ICU admission was best predicted with NEWS, however in patients with an infection or sepsis Modified Early Warning Score (MEWS) yielded better results for this outcome.ConclusionMEWS and NEWS generally had favourable results in the ED and AMU for all endpoints. Many studies have been performed on ED and AMU populations using heterogeneous prognostic scores. However, future studies should concentrate on a simple and easy to use prognostic score such as NEWS with the aim of introducing this throughout the (pre-hospital and hospital) acute care chain.     

Characteristics and outcome of patients presenting with acute Pancreatitis: A one-year descriptive study from a tertiary care center in Lebanon

AimTo determine the aetiology, hospital course, and outcome of patients diagnosed with acute pancreatitis (AP) presenting to the Emergency Department (ED) of a tertiary care center in Lebanon.Patients and MethodsUsing a retrospective cross-sectional study design, records of all patients presenting to the ED with elevated lipase over one calendar year (2016) were reviewed. Patients diagnosed with AP according to the revised Atlanta classification were identified.ResultsOver one year, a total of 24,133 adult patients visited the ED and 4,976 had serum lipase determination. Of those, 75 patients (mean age 59.4 ± 16.1; range 20–95; M:F 2.1) had confirmed AP accounting for 0.3% of adult ED visits. The most common etiologies were biliary (36%), idiopathic (16%), drugs (13%), and alcohol (11%). Intake of drugs known to be associated with AP was identified in 26% of patients. Alcoholic pancreatitis was more common in males, while biliary pancreatitis was more common in females (p less than 0.05 in both). 63 patients (84%) required regular hospital admission and only 1 (1.3%) required intensive care unit admission and passed away after multiorgan failure. Mean hospital stay was 4.0 ± 4.0 days (range 0–23) with mean hospital charges of $6,637 ± 8,496.ConclusionAcute pancreatitis accounts for a relatively small number of emergency visits in Lebanon. Leading etiologies are biliary and drugs, with a low contribution of alcohol compared to the West. The economic burden of AP is important, but outcomes appear largely favorable with an overall mortality of less than 2%.     

Initial pattern of elderly patients and effect on their orientation after their visit in the emergency departments. Results from a national study

PURPOSE: We have little information on the geriatric characteristics of elderly patients visiting the emergency departments (ED) in France. In order to develop an adapted prevention of the arrival of some elderly patients, the determinants of their arrival to the ED deserves to be better known. METHODS: A one-day cross-sectional study was conducted in French ED. A standardized questionnaire was used for each patient over 80 years (Pts), specifying the sociodemographic characteristics, the circumstances of visit to and care received in the ED, and the orientation of the patients after consulting the ED. RESULTS: On a sample of 1298 Pts, health event leading to ED started at home in 63.8% of cases. When the patients initiated themselves the recourse to health care (RHC), they called less often a general practitioner (61.9% of cases) than when the RHC was triggered by their family (69.6%, p=0.01). When a health care professional initiated the RHC, it was a GP in more than 80% of cases. Return to residence was more frequent when the patient triggered the RHC (34.5% versus 22.9% for the family and 16.0% for the professional health care, p<0,001). CONCLUSION: The actor of the decision of arrival to the ED has an impact in the RHC, in resources utilisation, and on the patient's orientation after coming in ED. The results of this study may help to design strategies aiming at avoiding unnecessary ED consultations of elderly persons.     

Increased HIV testing among hospitalized patients who declined testing in the emergency department

Health-care systems have serial encounters with many of the same patients across care settings; however, few studies have examined the role of reoffering HIV testing after a patient declines. We assessed whether an intervention to increase HIV testing among hospitalized patients was associated with increased testing among those who declined a test while in the Emergency Department (ED). We studied 8-week periods pre- and post-implementation of an electronic medical record (EMR)-based intervention to increase HIV testing among hospitalized patients. We included all patients 21–64 years old who had no prior HIV test, declined HIV testing in the ED, and were subsequently hospitalized. We used logistic regression to test for an association between time of hospital admission (pre- vs. post-intervention) and whether an HIV test was performed prior to discharge. Pre- and post-implementation, 220 and 218 patients who declined HIV testing in the ED were hospitalized, respectively. There were no significant demographic or clinical differences among patients pre- and post-implementation. Pre- and post-implementation, the median proportion of patients tested weekly was 6.7% (IQR 6.5%, 10.0%) and 41.4% (IQR 33.3%, 41.9%), respectively (aOR 6.2: 95%CI: 3.6, 10.6). HIV testing increased among hospitalized patients who declined a test in the ED after implementation of an EMR-based intervention. Almost half of the patients who declined testing in the ED ultimately underwent testing after it was reoffered during hospitalization, suggesting that the decision to undergo HIV testing is a dynamic process. Leveraging EMR resources may be an effective tool for expanding HIV testing, and testing should be reoffered to patients who previously declined.     

The use and effectiveness of an emergency department observation unit for elderly patients

STUDY OBJECTIVE: Emergency department observation units are cost-effective alternatives to hospital admission for selected patients. However, the use and effectiveness of these units in the elderly population is unclear. We sought to describe the use of an ED observation unit by elderly patients (>or=65 years), to determine whether the ED observation unit is effective for them in terms of ED observation unit length of stay and hospital admission rates, and to compare efficacy and return visit rates between younger and older patients. METHODS: This is a retrospective observational cohort study of consecutive adult patients sent to an ED observation unit from 1996 to 2000 at a high-volume tertiary care suburban teaching hospital. ED observation unit length of stay of less than 18 hours and admittance rates of less than 30% were used as indicators of efficacy. Diagnosis, length of stay, hospital admission rates, and 30-day return visit rates were compared between younger and older patients. RESULTS: Twenty-two thousand five hundred and thirty adult patients were observed, with 37.2% older than 65 years of age. The most common diagnoses in elderly patients were chest pain (24.0%), dehydration (11.7%), syncope (6.5%), back pain (4.6%), and chronic obstructive pulmonary disease (3.8%). Length of stay in the ED observation unit was longer for the elderly than younger patients but still averaged less than 18 hours (15.8 hours [95% confidence interval (CI) 15.7 to 16.0] versus 14.4 hours [95% CI 14.3 to 14.5], respectively). Elderly patients were more likely to be admitted from the ED observation unit than younger patients (26.1% versus 18.5%); however, their overall admission rate remained less than 30%. Compared with younger patients, the odds ratios for inpatient admission of elderly patients was highest for back pain (2.10; 95% CI 1.62 to 2.73), pyelonephritis (1.78; 95% CI 1.16 to 2.71), and chest pain (1.65; 95% CI 1.44 to 1.89). Thirty-day related return visit rates between age groups were similar (9.4% versus 7.6%). CONCLUSION: Elderly ED observation unit patients had ED observation unit lengths of stay and hospital admission rates that were effective for an ED observation unit setting and ED return visits rates that were comparable with those of younger patients.     

Évaluation gériatrique avant décision de remplacement valvulaire aortique par voie percutanée chez des patients âgés fragiles et suivi à un an : intérêt d’une collaboration cardio-gériatrique ?

BackgroundTranscatheter aortic valve implantation (TAVI) is a treatment for high-risk patients with symptomatic severe aortic stenosis. The aim of the study is to assess results of comprehensive geriatric assessment before TAVI and geriatrician advices about TAVI procedure feasibility. We report one-year outcomes after TAVI procedure.MethodsAll patients who underwent comprehensive geriatric assessment in geriatric day hospital before TAVI were prospectively included in Grenoble. We report characteristics of the patients, geriatrician advices about TAVI procedure feasibility and risks, and one year follow-up.ResultsTwenty-one frail elderly patients underwent geriatric assessment. The mean age was 85.4; demographics included cognitive impairment (76%), renal dysfunction (81%), NYHA functional class III or IV (48%). Eighteen patients were suitable for TAVI according to geriatric assessment, 8 underwent TAVI. None of the 3 patients who were not candidate for TAVI according to geriatricians were implanted. Cardiologists followed geriatrician advices for 56% of cases. Intensive care unit and cardiology stay were prolonged at 3.5 and 7.9 days, respectively. Six out of the 8 patients stayed in rehabilitation unit after TAVI. None of the implanted patients died at one-year follow up, despite of the common periprocedural complications: acute kidney injury, ischemic stroke, delirium, pacemaker, hemorrhage.ConclusionsCardiologists follow geriatrician advices about TAVI feasibility in frail elderly patients. Comprehensive geriatric assessment also helps preventing complications and providing quick assessment of occurring periprocedural and postprocedural complications. Optimal management of frail elderly patients undergoing TAVI is a multidisciplinary task involving cardiologists, anaesthetists and geriatricians.
