Context
Over the past 30 years there has been on average a 30% decrease in the number of hospital beds in France from 11.1 to 7.7 per 1,000 inhabitants.
1
On the other hand, the number of Emergency Department (ED) visits has doubled over the past decade.
2
As an example, we used to receive in our ED 52,000 visits in 2005, in 2011 we received 72,000 patients. Around 15% of our ED patients are hospitalized. In this context, it was decided 20 years ago to create ED observation units (OUs).
3
The initial aim of these units was to admit patients in need of 24-hour hospitalization either to do additional examinations or for sur­veillance/monitoring. In our ED, ~12,000 patients (17% of the total visits) had to be hospitalized in 2011; half of these patients were directly admitted to the hospital, the other half being admitted to our ED OU. Around 8% of our ED patients are more than 75 years old with a lot of comorbid­ities. Another specificity of our ED is that it is located in a poor neighborhood of Paris. As a consequence, we receive many patients with social difficulties: the homeless, elderly patients without relatives, etc. Of note, most of the hospitals change their conventional hospital beds into beds that can be used only during weekdays, (e.g. Monday morni ng to Friday evening) which decreases the beds available to the EDs on week­ends. In this context, we are going to describe the daily organization of our ED OU.
Emergency Department Observation Unit organization
Our ED OU is composed of 13 beds with a possible extension to 21 beds. It is located nearby the ED. Patients admitted to this unit are in need of 24-hour surveillance/monitoring before discharge, for example: psychiatric patients, patients who
wait for some specialized tests (MRI, scan, etc.), and patients who need an inpatient bed when no bed is available in the hospital. Two nurses are dedicated to this unit 24/7. From 9 a.m. to 6 p.m. a senior emergency physician and a resident in emergency medicine are dedicated to this area. Their work consists of an evaluation of all patients admitted to this unit the previous night, doing further examinations if needed and deciding the best destination for each patient: going back home, admission to an in hospital unit, or direct transfer to a rehabilitation center, etc.
To help physicians and nurses achieve this task, we have during the weekdays two dedicated social workers. They help in the social evaluation of the patients, especially the elderly and homeless people. With their help, it is sometimes possible to send back home some elderly patients. Our social workers organize a nurse visit to these patients in their home followi ng discharge. They also are in contact with rehabilitation centers. If a patient is too weak to go back home but doesnt need to be hospitalized, our social workers pre­pare a request to the rehabilitation centers. This system allows us to keep the beds in the hospital for the patients who need further exploration.
We also have the possibility of calling during weekdays a geriatric mobile unit composed of a physician and a nurse specialized in geriatrics.
4
They help the emergency ph ysician in the evalu­ation of some elderly patients with a lot of co mor­bidities. Rarely, it is possible to send back home some of these patients with a geriatrics consult­ation organized at follow-up.
Another issue that emergency physicians have to face is the care of patients with a chronic disease in need of palliative care. Over the last years we have had to keep these patients in our OU until their death because no palliative bed is available.
080
21:38:46
Ideally the ED OU should be empty at the beginning of the night shift: from 6 p.m. to 9 a.m. Due to the shortage in inpati ent beds and the overcrowding of our ED, elderly patients with comorbidities are admitted to the ED OU.
5
We have on a regular basis four to five patients that spend more than 24 hours in our OU.
During the night shift, from 6 p.m. to 9 a.m, if needed, the nurses call the emergency physician on shift to see a patient or review a test result.
Perspectives
Our main objective is to maintain the length of stay in the OU below 48 hours. To achieve this goal, we work closely with the other departments of our hospital so everybody in the institution knows that
our ED needs around 35 beds every 24 hours. We also work with the other departments on the kind of patients that they would like to take charge of. The principle difficulty that persists concerns the elderly patientsin need of a bed in the geriatric department. Due to the lack of beds in the geriatric department and the resistance of some of the other departments to take charge of these patients, these patients may spend more than 48 hours in our OU, increasing the mean length of stay.
To conclude, the ED OU has become, over the last few years, a mandatory tool to manag e patients in need of hospitalization. The presence of a senior emergency physician seven days a week allows hospitalizing only the patients that really need it. The presence of social workers appears to be very helpful in our ED OU.

Background and Clinical Need
In Germany, of the adults with medical emergen­cies seen in the emergency department (ED), around 10% of patients present with a chief com­plaint of chest pain. Of these, around 50% suffer from an acute coronary syndrome (ACS), and an acute myocardial infarction (AMI) is diagnosed in roughly 20% of the chest pain patients.
1
It is one of the most difficult challenges in Emergency Medicine (EM) to identify chest pain patients with or in acute danger of an AMI and those with non-ischemic or non-cardiac underlying prob­lems. Both the incorrect classification into the high-risk group and the erroneous classification into a low-risk group can have negative conse­quences for the patient as well as for the health care system. The rate of patients who were mis­takenly discharged from the ED with myocardial infarction has been described to lie between 2 and 8% and the risk-adjusted mortality ratio for those who were not hospitalized, as compared with those who were, was significantly increased.
2
On the other hand, the admission of chest pain patients without ACS puts patients at risk of inappropriate or unnecessary diagnostic testing and treatment with the potential for side effects from the treatment, and poses a burden to costs for the health care system and resource availabil­ity in the ED . In summary, chest pain is a frequent symptom in adults seen with a medical emergency in the ED and can be caused by life-threatening diseases, which need to be diagnosed or excluded in a standardized patient workup.
TheEstablishmentofChest Pain Units in Germany
Aware of the diagnostic challenges, specialized observation units (OUs) or chest pain centers (CPCs) have been set up in the United States and the United Kingdom since the beginning of
the 1990s and clinical trials hav e shown their great success in improving patient outcome as well as economic resource utilization.
3,4
In Germany, the first Chest Pain Units (CPUs) were established at the beginning of this century. In 2008, the Task Force CPU of the German Society of Cardiology (Deutsche Gesellschaft für Kardiologie [DGK]) defined minimal standard criteria for a CPU and started a certification campaign to avoid misuse of the term Chest Pain Unit and to guaran­tee a systematic approach.
5
The DGK standards follow the Guidelines of the DGK for patients with ACS
6,7
and include requirements regarding the premisesof the CPU, technical equipment, diagnos­tic measures, therapeutic strategies, cooperating partners, and institutions as well as training and professional experience of staff.
5
Since the first cer­tification in October 2008, 141 German CPUs have been certified by the DGK (as of April 17, 2012) and numbers are rising. The DGK estimates that 250 CPUs are necessary to cover the whole German territory.
8
The Concept of a CPU
The overall aim of a CPU is to optimize the diagnostic and therapeutic management process for patients with acute chest pain whilst meeting the requirements of current evidence-based guidelines to improve patient outcome and reduce costs. Figure 76.1 illustrates the standard­ized flowchart of patient management in a CPU. It is important to stress that the starting point for standardized patient care involves all patients with all kinds of chest pain and not only patients with ACS. Optimized care is delivered not only to patients with ACS but also to those with non­ischemic and extra-cardiac chest pain.
Important prerequisites to fulfill certification requirements are the availability of a cardiac catheterization laboratory 24 hours a day, 365 days a year, a minimum of four monitored beds, and

Figure 76.1 Chest Pain Unit:1Chest pain of all kinds,2Angina pectoris equivalents. This could be dyspnea, atypical chest pain, or other symptoms and needs to be judged individually. Suspicion of myocardial ischemia can also result from a series of events, e.g., arrhythmogenic syncope in a patient with a high-risk cardiac profile,
3
There are three categories of patients: STEMI, NSTEMI and chest pain patients without elevated cardiac markers or acute ST elevation MI. STEMI and NSTEMI patients are monitored in a Coronary Care Unit. Stable chest pain patients without elevated cardiac markers or acute ST elevation MI can be monitored in a chest pain unit. ST-elevation myocardial infarction (STEMI). Patients with STEMI are treated according to current guidelines. Standard operating procedures (SOPs) need to be available at a Chest Pain Unit (CPU) and regular training needs to be available,
4
Non-ST-elevation myocardial infarction (NSTEMI). Patients with NSTEMI are treated according to the current guidelines. Standard operating procedures (SOPs) need to be available at a CPU and regular training needs to be available.Patients with NSTEMI are monitored on a Coronary Care Unit (Intensive or Intermediate Care Unit).
5
Patients with typical complaints but without elevated cardiac markers (troponin) and without ST-elevation are immediately transferred to the CPU.
6
Patients with atypical complaints are in most cases transferred to the CPU, unless myocardial ischemia is
extremely unlikely.
7
Cardiac markers. Patients on a CPU should be tested for cardiac markers, preferably troponin, at admission and again after 6–8 hours; earlier time points (e.g., 3h) are discussed with high-sensitive troponin assays,
8
Imaging. In addition to serial ECG and marker testing, imaging
techniques can be indicated (e.g., echocardiography, cardiac MRI, cardiac CT, SPECT).
9
Risk factors. Risk factors in this sense are refractory angina, diabetes mellitus, TIMI risk score > 3 points or GRACE-score > 140.10Stress test. After exclusion of acute myocardial infarction, a stress test should be performed as soon as possible (bicycle stress test, stress echocardiography, stress myocardial scintigraphy, stress-MRI).
11
Differential diagnosis. In case of a negative evaluation the differential diagnoses of the acute chest pain should be sought. The most important diagnoses are pulmonary embolism, peri/myocarditis, and aortic dissection. Orthopedic correlates and gastrointestinal diseases can mostly be evaluated in the primary care system.

24-hour availability of a laboratory as well as availability of echoc ardiography, but also the availability of computerized tomography (CT), magnetic resonance imaging (MRI) and abdom­inal ultrasound for the evaluation of differential diagnoses.
An important aspect of the CPU concept is to create an environment that assures the implemen­tation of evidence-based guidelines. Minimal standard criteria of the DGK include the intro­duction of algorithms for STEMI (divided in pre­announced and unannounced STEMI), NSTEMI, stable and unstable angina pectoris, hypertensive crisis, acute pulmonary embolism, acute aortic syndrome, cardiogenic shock and resuscitation; and recommendations for implementation of additional standard operating procedures (SOPs) and algorithms. Additionally door-to-balloon times for patients with STEMI and NSTEMI have to meet the guideline requirements.
5
The Effect of CPUs in Germany
A number of secondary data analyses and clinical trials have shown the beneficial effect on patient outcome and on resource utilization of patient management in a CPU as opposed to manage­ment in a conventional inpatient setting in the United States and the United Kingdom.
3,4
The same is true for results of the evaluation of CPUs in Germany. The University of Mainz was the first institution with a certified CPU in Germany. They retrospectively evaluated patient outcome
(combined endpoint of AMI, stroke, or death of all causes within 1 year after the initial event), length of stay (LOS) as a criterion for economic benefit, and patient satisfaction in their institu­tion, using patient data from before and after the implementation of their CPU.
9–11
In the popula­tion of all patients with chest pain, no outcome benefit could be shown. In the group of patients with ACS though, treatment in a conventional ED showed a significantly increased hazard ratio for the combined endpoint and a reduced 1-year sur­vival rate as compared to CPU treatment.
9
Like­wise, the LOS of patients with ACS was significantly shorter after CPU implementation
10
and patient satisfaction was markedly increased.
11
Conclusion
The concept of specialized Chest Pain Units in Germanyisrelativelynewandnation-widecover­age still has to be achieved. Due to the dedicated work of a Task Force of the German Society of Cardiology and the certification process, the term CPU is standardized and institutions have to meet at least defined minimalrequirements. Evidence for the prognostic and economic benefit of German CPUs has only been evaluated by retrospective data analysis in one center. Large prospective controlled clinical trials as well as the evaluation of guideline adherence, management processes, and the eco­nomic benefit considering all patients with of all kinds of chest pain are still lacking.

Emergency Me dicine is deputed to manage clinical emergencies. At the end of this process the Emer­gency Department (ED) physician must decide for final disposition: discharge or admission of the patient. Today, ED overcrowdin g represents an international crisis that may negatively affect the quality and the access to health care and is associ­ated with an increased risk of in-hospital mortal­ity.
1,2
As a consequence of the lack of available beds
for acute patients hospitalization and the request of more appropriate disposition, the ED mission gradually changed from Adm it to workto
Work to admit,indicating the need to create a new filter system for hospital admission.
3
The Observation Unit (OU) is the third opportunity for ED physicians to manage clinical emergencies, in an attempt to avoid the risk of inappropriate discharge and/or hospitalization. In Italy, observation practice in the ED is very common and widespread, trying to face off the problem of the acute patients long length of stay (LOS) in the ED, waiting for bed allocation, with consequent ED overcrowding.
4
According to Ital-
ian data, about 5 to 7% of patients referring to the
Figure 77.1 The OU ward in SantAndrea Hospital, Rome.
082
21:38:55
ED need to be observed for a time, requiring care for 24–36 hours. Of these patients, 10 to 30% are admitted, while 70–90% are discharged.
3
In the 1990s, the National Health System (NHS) decided to introduce in Italy observation medicine (OM) with the aim to impact the in­hospital admission decision. The Italian Presi­dential Decree of March 27, 1992, enhanced the power of the local regional government in terms of public health activities planning, funding, organization, and control.
5,6
In this document the activation of OU wards was introduced with the objective to ameliorate the decision for hos­pital admission from the ED, through an inten­sive and accurate stabilization of critical patients who often do not need subsequent hospitaliza­tion. This project was also coupled with a common teaching process for ED doctors and nurses to better use the emergency "evidence based medicine." The proper use of the OU was aimed to:
7
decrease the risk of medical mistakes
through accelerated management protocols;
reduce inappropriate admissions by
improving the function of the filter;
decrease the LOS; reduce the costs; improve the quality of health care perceived
by users.
Systematic guidelines were created and approved in the attempt to unify the different approach of every Italian region to OU management.
8
These guidelines introduced the all-comprehensive daily reimbursement, of the value of 220/patient not hospitalized after observation in ED. Exceptions are Region Lazio (275),
9
Region Veneto (200),10and
Region Alto Adige (250 ).
11
In the OU, accelerated management protocols allow facilitation of patient care for selected ED patients and improve the observation quality of patients at low riskfor complications.

LOS in the OU is usually not less than 6 hours and not more than 24 hours, with exceptions arising from the requirements of individual regions or specifically of the single hospital (max­imum of 36 hours).
9,12,13,14
From a structural point of view, the OU is a dedicated area nearby the ED, providing the same services as the ED. In particular, there must be available a fair and appropriate (relative to inpati­ent beds), highly skilled, dedicated, 24-hour nurs­ing staff, support staff, and medical staff; a laboratory providing for quick laboratory tests with an ability to respond 24 hours a day; and a conven­tional radiology and CT scan for the total body 24 hours a day with real time x-ray responses. All medical and nursing activity must be computerized and available: there should be a clinical diary for each patient and, at discharge time, a brief report for the general practitioner must be delivered.
Depending on the existing buildings, there are two different possible settings: 1) an open space with center console and 2) individual rooms or compartments with central monitoring. The number of beds in each OU is identified using two equivalent criteria: 2% of the hospitals total number of beds or one bed for every 4,000–8,000 access to the ED. A portion of beds, on average 50%, must be provided with hemodynamic and respiratory monitoring with pulse oxime ter. Each bed should be provided with oxygen and vacuum and at least one monitor defibrillator/pacer, one noninvasive mechanical ventilator able to work in PSV/PEEP mode, one multidisciplinary ultra­sound, one electrocardiograph, an appropriate number of glucometers, of sphygmomanometers, of infusion pumps, and intubation/CPR staff.
4
(See Chapter 5 on Obse rvation Unit Design)
In particular, in SantAndrea Hospital, Rome, the OU is provided with eight multiparametric monitored beds divided into two rooms with a central core working station. (Figure 77.1) Point­of-care laboratory system test for blood gas
analysis, troponin, brain natriuretic peptide (BNP), neutrophil gelatinase-associated lipo cain (NGAL), and urine drug abuse test are included. Furthermore, point-of-care ultrasound equip­ment are available for abdominal, thoracic, and cardiac disease dedicated protocols. Moreover, a continuous data recording system for EKG (24 hours) is provided for detecting complex car­diac arrhythmias and an online system allows the prompt visualization of x-ray imaging and reports. Ventilator systems for invasi ve and non­invasive ventilation are also provided.
In Italy differences exist between each regional state on the lists of diseases eligible for OU admis­sion (but these lists should be interpreted with some flexibility). In every hospital and in particu­lar in every ED dedicated structure, appropriate diagnostic and therapeutic paths are drawn for more common diseases, shared after the appro­priate contextualization as the Guidelines National Plan also provides.
8
(Figure 77.2)
Table 77.1 shows the most suitable conditions for short observation admission in Italy.
8,15
Each region has its own protocols for the management of the listed acute conditions.
Monitoring the quality of care and service
delivery differs in each region, and it is important for the development and implementation of best practicemodels for OM.
