Risk factors for heat related death during the August 2003 heat wave in Paris, France, in patients evaluated at the emergency department of the Hôpital Européen Georges Pompidou.

OBJECTIVES: This study sought to determine the risk factors for short term mortality in the victims of the heat wave of August 2003 in France from among patients evaluated in our emergency department (ED). It was hypothesised that age, temperature, and some long term therapies and pre-existing pathologies were factors associated with short term mortality. METHODS: A retrospective analysis of a seven day period. Four experts decided blindly, in pairs, whether a patient had presented with a heat related problem. Inclusion criteria were: core temperature > or =38 degrees C and/or clinical signs of dehydration. Comparisons were made between the survivors and one month non-survivors for 57 different items. Short term mortality was defined as death in the ED or within the first month of the ED visit. RESULTS: Of 841 patients attending the ED in the study period, 165 were included in the study, of which most were elderly women. Thirty one (18.8%) died within one month. Factors associated with short term mortality were: a greater degree of dependent living; more severe clinical condition on admission (higher temperature and heart rate, lower blood pressure, hypoxia, and altered mental status); higher values of blood glucose, troponin, and white blood cell count; lower values of serum protein and prothrombin levels; pre-existing ischaemic cardiomyopathy; pneumonia as associated infection; and previous psychotropic treatment. The total number of survivors at one year was 91. CONCLUSIONS: Although this study is limited because of the small sample size, the results have helped determine factors useful for future identification of patients at greatest risk of death in order to implement a more efficient patient care protocol.

Outpatient care in emergency departments: feasibility and comparison of three strategies for follow-up.

The outpatient population using the emergency department (ED) is increasing and so is the risk of not admitting people who need it. There is, thus, one important question: are the services delivered appropriate to the needs of these ED outpatients? Follow-up of non-admitted patients after a visit to the ED is a prerequisite for the evaluation of these health services. A multicentric follow-up study was thus performed in order to assess the possibility of contacting outpatients after a visit to the ED. Three randomized follow-up methods were compared: (1) telephone call 1 week after the emergency department visit; (2) telephone call 2 weeks after the visit; (3) telephone call 4 weeks after the visit. The follow-up rate did not change depending on whether patients were contacted at 1, 2 or 4 weeks after the visit. The success rate was 78.6%, 85.6% and 74% respectively (NS). In each strategy, 50% of patients were contacted at the first telephone call, 20% at the second telephone call and 10% by mail. Thus, in a group of outpatients who gave their consent to be called, the follow-up was found to be feasible with a high success rate whatever the time between the visit and the phone recall.

Using the hospital emergency department as a regular source of care.

OBJECTIVES: to evaluate the proportion of the patients who report the emergency department as their regular source of care and to describe the demographics and health status of this population. DESIGN: A cross-sectional study was performed at the emergency department in two hospitals (around 12,000 visits per year each). Subjects were interviewed using a standardised questionnaire, before and after the emergency department visit. SETTING: The medical emergency department of two university hospitals, one in Paris and one in Besançon (France). SUBJECTS: Each patient aged 15 and more attending the emergency department for a visit during forty randomly selected periods of 12 hours was included. MAIN OUTCOME MEASURES: Self report of the utilization of the emergency department as a regular source of care. RESULTS: Fourteen percent of the patients cited the emergency department as a regular source of care in Paris, and 3.3% in Besançon. In Paris, young age, being born outside of France, homelessness or precarious housing, lack of social support in case of illness and lack of health insurance were independently associated with this health care utilization behavior. CONCLUSIONS: From a public health point of view, the patients reported to use the emergency department as a primary health care structure should not be considered as 'inappropriate' or 'abusers'. Specific health needs have been found, which would require some continuity of care, a task for which the emergency department is not organised nowadays.

Predicting the outcome in elderly patients of hospital admission for acute care in Paris, France: construction and initial validation of a simplex index.

OBJECTIVE: To develop a simple index able to identify at an early stage those elderly patients at high risk of requiring discharge to a residential or nursing home after admission to hospital for acute care. For these patients, early discharge planning might lead to a more effective management and reduce the length of hospitalisation. DESIGN, SETTING, AND PATIENTS: This was a prospective study conducted in two teaching hospitals in Paris, France. A total of 510 consecutive patients was included. They were aged 75 years or more and had been admitted to acute medical care units through the emergency department. MEASUREMENTS: Demographic data, social support, physical disability, mental disability, and pathologic status were assessed shortly after admission (within 24-48 hours). MAIN OUTCOME MEASURES: Outcome of hospitalisation was defined as discharge to home or residential/nursing home. RESULTS: The index, developed by multiple logistic regression, included six variables: the wish of patients' principal career about their returning home after acute hospitalisation, presence of a chronic condition, ability to perform toileting, ability to know the name of the hospital or the city, their age, and their living arrangements. The sensitivity of the index in identifying patients at high risk of requiring discharge to a residential/nursing home was 74.4%, the specificity 63.8% the positive predictive value was 57.8%, and the negative predictive value was 80.6%. CONCLUSIONS: The simple index, using data available very early in the course of hospitalisation, provides an accurate prediction of the hospitalisation outcome. The performance of the index should be tested in other populations and the practical benefits of risk screening should be assessed in a controlled trial to evaluate whether the intervention is useful and without any adverse effects.

[Stunned myocardium or hibernating myocardium? Apropos of a case].

The authors relate a case report of unstable angina pectoris accompanied by a well-documented stunned myocardium phenomenon. Stunned and hibernating myocardium resulting from an acute or chronic coronary ischaemia on the myocardium are notions which widely govern revascularisation indications, especially after a myocardial infarction. At present, their detection is based on isotopic methods and stress echocardiography.

Non-urgent care in the hospital medical emergency department in France: how much and which health needs does it reflect?

OBJECTIVES: The goal was to describe the use of the medical emergency department as a source of non-urgent medical care in order to assess unmet health care needs among its users. The specific objectives were thus to assess the proportion of emergency department visits for non-urgent medical care and to describe those who used the department for this reason. DESIGN: A cross sectional study was performed at the emergency department in two hospitals (around 12,000 visits per year each). Subjects were interviewed before and after the visit using a standardised questionnaire. SETTING: The medical emergency department of two university hospitals, one in Paris and one in Besançon (France). SUBJECTS: Each patient aged 15 and more attending the emergency department for a visit during 40 randomly selected periods of 12 hours was included. MAIN OUTCOME MEASURES: A definition of urgent care was adopted before the beginning of the study. Four expert judgments were then used for each case to determine whether the reason for the visit was urgent or not. RESULTS: Altogether 594 patients in the Paris emergency department and 614 in the Besançon one were included. In Besançon, the patients were older, a general practitioner was more often cited as the regular source of care, and the percentage of subsequent hospital admission was higher than in Paris (71% versus 34%). The non-urgent visits were estimated to account for 35% and 29% of the visits in Paris and Besançon respectively. Patients using the emergency department for a non-urgent visit were younger than other patients. More of them were unemployed, homeless, born outside of France, and without health insurance. CONCLUSIONS: Non-urgent use of the emergency department was observed in about one third of the visits. Groups using the department for primary care and/or non-urgent care were mostly young and socially fragile, with no regular source of health care. Their poor health condition suggests that there is a need for a structure providing primary care both inside and outside 'normal' working hours.

Returning home after acute hospitalization in two French teaching hospitals: predictive value of patients' and relatives' wishes.

Identifying elderly patients who are unable to return home immediately after acute hospitalization is difficult. For these patients, early planning of discharge might reduce the length of hospitalization. We conducted a cohort study to investigate the roles of patients' characteristics and patients' and principal carers' wishes about patients returning home in predicting the outcome of hospitalization for 510 patients aged 75 years or more admitted to acute medical care units via the emergency departments of two teaching hospitals in Paris (France). Patients' characteristics and patients' and principal carers' wishes were investigated within 24-48 hours of admission. The outcome of hospitalization was defined as discharge to home or residential/nursing home. The opposition of the principal carer to a patient returning home was the most powerful predictor of discharge to a residential/nursing home. Advanced age, living alone, disability in Activities of Daily Living, altered mental state and presence of a chronic condition fatal within 4 years were also independently associated with discharge to a residential/nursing home. The patient's wishes were predictive in univariate but not in multivariate analysis. These results suggest that the principal carer's wishes about a patient returning home might be taken into consideration early in a hospital stay for more effective discharge planning.

Appropriateness of admissions: the French experience.

The French studies using the Appropriateness Evaluation Protocol (AEP) were developed within the framework of medical audit by local teams, analysing their own practice, in order to improve the quality of care. Four studies were analysed in this review. They were performed in emergency departments and data were collected concurrently. The reliability and validity of this French version of the AEP was assessed. The high reliability of the AEP was found to be useful to measure trends or differences between groups. The percentages of inappropriate admissions observed in the studies ranged from 18 to 25%. The hypothesis that the rate of inappropriate admissions would be highest among the elderly was not confirmed in Paris. Homelessness was the only social factor related to a high rate of inappropriate admissions in three of the studies. In one study, age and lack of social support were found to be risk factors for inappropriate admissions. The study of the causes of inappropriate admissions was important, since they were to be used as an indicator of systemic problems in the organization of health care delivery. A distinction was made between appropriate and justified admissions on both a systemic and an individual level. In conclusion, AEP was found to be an indicator that was both reliable and useful to identify quality of care problems. Among the factors found to be related to inappropriate admissions, the internal organization of the hospital proved to be one of the main reasons and a target for improvement.

[Hospital discharge planning and length of hospital stay in elderly patients admitted through the emergency department].

A prospective study was organized in two teaching hospitals in Paris, including 426 elderly patients aged 75 and more, who had been hospitalized through the medical emergency department. The goal of the study was to assess the influence of difficulties of orientation at discharge on the length of stay, independently of other risk factors. The mean length of stay was 18.3 +/- 15.4 days. Orientation at discharge toward a social or a nursing care institution was associated with a 12 days longer mean length of stay than a home discharge. A longer length of stay was also associated with: a strictly social problem at admission, the diagnoses of dementia, confusion, social problem, fall or general health impairment, a short or long-term fatal prognosis, a poor mental status, refusal of home discharge as expressed by the referent person. Multivariate analysis showed that discharge toward a social or a nursing care institution was the first explanatory factor, explaining 12% of variance. These results suggest that the hospital discharge management has a major influence on the elderly length of hospital stay. Therefore, an interdisciplinary care management, including social and geriatric evaluation as soon as the patient is admitted at the emergency department, should be evaluated, in order to avoid problems of orientation that may occur at discharge.

[Outcome of patients with Eisenmenger syndrome. Apropos of 62 cases followed-up for an average of 16 years].

In an era when heart-lung transplantation offers a therapeutic option for patients with Eisenmenger's syndrome, it is important to assess the natural history of this condition. With this objective the authors studied 62 patients followed-up by the same cardiologist. The average follow-up period was 16 years, but 22 patients were followed up for over 20 years. The average age at death was 29 years. It differed significantly for genetically normal patients (31 years for 21 fatalities) compared with a population of trisomics (21 years for 6 fatalities). Half the patient population lived for over 30 years. Fourteen of the 27 deaths occurred during the third decade and only 4 before the age of 20. The probability of surviving 10 more years for a 20 years old genetically normal patient was 56%. The causes of death in the 19 cases in which it could be established were: 5 sudden deaths, 4 right heart failures, 3 massive haemoptyses, 3 pulmonary emboli, 2 pneumonias and 2 peroperative deaths. The functional disability was nearly always minimal or mild, enabling the patient to work: 24 of the 45 non-trisomic patients had full-time jobs. Pregnancy was a poor prognosis factor and could be lethal (2 deaths due to pulmonary embolism in the post-partum period). A heart-lung transplantation would only seem to be justified in patients with severe symptoms, polycythaemia, irreversible right heart failure and/or haemoptysis.

Appropriateness of admission in an emergency department: reliability of assessment and causes of failure.

The validity of a modified version of the appropriateness evaluation protocol was assessed in a sample of patients aged 15 and over admitted by means of the emergency department of one of the Paris hospitals. As measured among 371 patients, the reliability of the indicator was high. The prevalence of inappropriate admissions (IA) was found to be 20% using the expert opinions and 25% the instrument. Homelessness was associated with a higher prevalence of IA (34%). Other social factors and age were not related to IA. According to the experts' opinions, difficulties in organizing the continuity of care for patients examined in the emergency room were one of the main causes for IA.
