[Relative effects of external and internal factors on emergency department efficiency]

State of emergency medicine in Spain

Spain has universal public health care coverage. Emergency care provisions are offered to patients in different modalities and levels according to the characteristics of the medical complaint: at primary care centers (PCC), in an extrahospital setting by emergency medical services (EMS) and at hospital emergency departments (ED). We have more than 3,000 PCCs, which are run by family doctors (general practitioners) and pediatricians. On average, there is 1 PCC for every 15,000 to 20,000 inhabitants, and every family doctor is in charge of 1,500 to 2,000 citizens, although less populated zones tend to have lower ratios. Doctors spend part of their duty time in providing emergency care to their own patients. While not fully devoted to emergency medicine (EM) practice, they do manage minor emergencies. However, Spanish EMSs contribute hugely to guarantee population coverage in all situations. These EMS are run by EM technicians (EMT), nurses and doctors, who usually work exclusively in the emergency arena. EDs dealt with more than 25 million consultations in 2008, which implies, on average, that one out of two Spaniards visited an ED during this time. They are usually equipped with a wide range of diagnostic tools, most including ultrasonography and computerized tomography scans. The academic and training background of doctors working in the ED varies: nearly half lack any structured specialty residence training, but many have done specific master or postgraduate studies within the EM field. The demand for emergency care has grown at an annual rate of over 4% during the last decade. This percentage, which was greater than the 2% population increase during the same period, has outpaced the growth in ED capacity. Therefore, Spanish EDs become overcrowded when the system exerts minimal stress. Despite the high EM caseload and the potential severity of the conditions, training in EM is still unregulated in Spain. However, in April 2009 the Spanish Minister of Health announced the imminent approval of an EM specialty, allowing the first EM resident to officially start in 2011. Spanish emergency physicians look forward to the final approval, which will complete the modernization of emergency health care provision in Spain.

[Grade of knowledge about the advance directive document by the chronic patient who comes to the emergency department]

OBJECTIVE

To evaluate the patient's and their caregiver's knowledge of the advance directive document (ADD) in patients with chronic diseases who come to the emergency department due to decompensation and their caregivers. To discover the patient's willingness and associated factors to draw up an ADD.

MATERIAL AND METHODS

A descriptive cohort study including patients with an acutely decompensated chronic evolving disease attending the ED medicine section at an urban tertiary teaching hospital was performed. The patients' demographic and clinical variables were recorded. After control of their symptoms, an anonymous structured oral interview was also administered. Dependent variables included were previous knowledge of the ADD, and the patient willingness to draw it up. The relationship among independent and dependent variables was analyzed.

RESULTS

A total of 380 people (190 patients and 190 carers) were analyzed. Compared with patients, carers were more frequently women (76% vs 42%, p<0.001), younger (58+/-15 vs 73+/-12, p<0.001), and had a better knowledge of the disease (88% vs 74%, p<0.001) and of the ADD (28% vs 16%, p<0.001). Only 5% of the patients had received ADD information from their physician. The only factor associated with the patients' previous knowledge of the ADD was to have completed at least secondary school (p<0.05). Forty-six percent of patients were favorable to the drawing up of an ADD. The only variable associated with such a willingness was to be 70 or younger (p<0.05). Eighty-eight percent of the patients were in favor of the distribution of information leaflets in the ED.

CONCLUSIONS

There is poor patient and carer knowledge regarding the ADD among patients with chronic diseases. Nonetheless, almost half of patients would be willing to draw up an ADD. EDs can contribute to improve the information about it.

Estimación de la actividad en urgencias y su relación con la provisión de camas de hospitalización

BACKGROUND AND OBJECTIVE

To find out if the daily emergency department (ED) census and daily ED admittances can accurately be foreseen based on the number of visits arrived on ED within the first shift hours.

PATIENTS AND METHOD

For 6 consecutively months, the number of ED visits from 6 AM to 10 AM (early visits), and from 10 AM to next day 6 AM (daily ED census) was recorded, along with the number of both daily hospital and ED admittances from 6 AM to 6 AM. The analysis was performed for the ED as a whole, and for each one of its sections.

RESULTS

A significant direct correlation was seen between the early visits and daily ED census. This relationship was even greater as considered the ED as a whole (R2 = 0.25; p < 0.001). A direct correlation was also found between daily ED census and daily admittances (R2 = 0.19; p < 0.001).

CONCLUSIONS

The number of early ED visits is an important tool to accurately predict the daily ED census and the number of in-hospital beds needed for ED patients.

Repercusión de la falta de camas de hospitalización en la actividad de un servicio de urgencias hospitalario

BACKGROUND AND OBJECTIVE

To determine the effect that the lack of inhospital beds exerts on emergency department performance.

MATERIAL AND METHOD

Two different time periods with comparable daily census, but significantly different bed availability. Variables assessed were general emergency department performance markers, emergency department effectiveness markers and objective and subjective quality markers.

RESULTS

All variables got worse within lower bed availability period, and reached a change magnitude between 0% and 300% when compared with control period. However, a statistical difference was only achieved in emergency department occupation rate (+14%; p < 0.001), rate of patients waiting to be admitted (+100%; p < 0.001), patients waiting to be seen (+60%; p < 0.01), waiting time to be seen (+83%; p < 0.001), time to employed for first medical assessment and treatment (+44%; p < 0.01), and patients left without being seen (+90%; p < 0.05).

CONCLUSIONS

The lack of inhospital beds for patients admitted from the emergency department leads to a remarkable worsening in its function and performance.

Derivación sin visita desde los servicios de urgencias hospitalarios: cuantificación, riesgos y grado de satisfacción

BACKGROUND AND OBJECTIVE

After triage assessment, some hospitals refer emergency department (ED) patients with minor chief complaints to off-site clinics. The potential for 2 different referral models introduced in 2 urban hospitals was assessed, as well as the suitability of this measure.

PATIENTS AND METHOD

After triage assessment, patients with minor complaints were identified. ED from Hospital Clínic of Barcelona (HCB) proposed that these patients should be referred to a hospital affiliated off-site clinic, whereas ED from Hospital Mútua de Terrassa (HMT) tried to refer such patients to their primary care setting. Within a year, we assessed on both ED the following items: number of arrivals, percentage of proposed referrals (PR), percentage of accepted referrals (AR), percentage of carried-out referrals (CR: patients who, once discharged, really attended the other setting), and percentage of returned referrals (RR) to the ED, as well as return reasons, and the percentage of returned patients finally admitted. The degree of patient satisfaction was evaluated by means of a telephone survey.

RESULTS

From both ED, 44,764 arrivals and 7,297 (16.3%) PR were registered. The percentage of AR and CR was 94.3% and 75.3%, respectively. The percentage of PR from HMT was higher (18.7% vs 13.1%; p < 0.001), yet HCB obtained a greater percentage of AR (98.9% vs 92%, p < 0.001) and CR (93.7% vs 65%; p < 0.001). The percentage of RR from both ED was 1.5% (2.8% vs 0.4%; p < 0.001). Among returned patients, 12 of them (0.17% respect to AR) were finally admitted. Only 41% of patients who were found to be eligible for direct discharge would have agreed with being referred to another clinical setting, but after the experience, up to 93% of them said they would go through it again. HMT gave referral information to patients faster than HCB (p < 0.05), but HCB got a better model evaluation (p < 0.01), a greater medical complaint solution (p < 0.05), and generated a smaller number of subsequent consultations (p < 0.05).

CONCLUSIONS

After a rapid triage assessment, a percentage of patients arriving on EDs may be directly and safely discharged and referred to other clinical settings. This is achieved by both proposed models without additional risks for patients. However, patients feel more satisfied with an hospital-affiliated off-site clinic instead of their primary care setting.

[Effect of the incorporation of a general practitioner on emergency department effectiveness]

BACKGROUND AND OBJECTIVES

To know the effect that the presence of a general practitioner (GP) has on emergency department's effectiveness, efficiency and health care.

PATIENTS AND METHOD

Prospective interventional study carried out in the emergency medicine unit fast track area (FTA), which is ideally opened from 8 am to 12 am, and staffed by 2 residents.

INTERVENTION

8 resident hours (from 4 pm to 12 am) were substituted by 8 GP hours. The study period was August 2002 (GP presence), and the control period, October 2002. From each period, 10 days and 100 patients were randomly selected. From each day, FTA census (P), percentage of revisits and patients leaving without being seen, elapsed time to FTA actual closing (OT), percentage of patients moved to the observation area, and percentage of admissions were recorded. From each patient, epidemiological and clinical characteristics, waiting time to be seen (WT), number of tests performed, elapsed time to treatment (TT), and length of stay (LOS) were collected along with the number of patients finally discharged without hospital specialist consultation and those discharged with no test ordered. To assess perceived care quality, a telephone survey was performed. Three effectiveness indexes were defined and determined: P/WT (E1), P/OT (E2), and perceived care quality/perceived WT (E3). Finally, fixed and variables costs (C) from both periods were calculated, and cost-effectiveness analysis for each effectiveness index and period performed.

RESULTS

Periods showed no differences regarding daily census and patient characteristics. In the study period (GP presence), all time variables significantly improved: 20% reduction in WT, 25% in TT, 36% in LOS, and 17.5% in OT. A decrease in the number of tests ordered (41% less), in the percentage of patients moved to the observation area (78% less), and in the revisit rate (75% less) was also noted. Finally, E1 improved in 77% and E2 in 51%. Cost-effectiveness analysis clearly supported the study period, showing a decrease in C/E1 (55% less), in C/E2 (33% less), and in C/E3 (6% less). From the telephone survey, no differences between periods were detected except a perceived WT in the study period lower than that in the control period.

CONCLUSIONS

The presence of a GP in a FTA leads to an improvement in the effectiveness and quality of care received by attended patients. In addition of these important features, this presence is also efficient. Therefore, it is an intervention that could be taken into account by administrators to better manage emergency departments.

[Hospital emergency rooms]

Overuse of hospital emergency rooms (HERs) is parallel to their controversy. To understand this problem, some concepts should be first clarified. In HERs, there are some intrinsic aspects which are directly related to the emergency itself and thus cannot be modified (intermittent patient flow, need to prioritize, difficulty to achieve a rapid diagnosis, influence of time on treatment, value of clinical follow up, patient's expectations, impact of HER on the overall hospital working dynamics). On the other hand, there are some extrinsic aspects which indeed are not related to HER itself but are rather historically associated with it (precarious structure, delay on admission, lack of privacy, inadequate triage of cases, lack of professionalization); these latter aspects may be potentially modified and should be reconsidered.

Analysis of patient flow in the emergency department and the effect of an extensive reorganisation

OBJECTIVES

To evaluate the different internal factors influencing patient flow, effectiveness, and overcrowding in the emergency department (ED), as well as the effects of ED reorganisation on these indicators.

METHODS

The study compared measurements at regular intervals of three hours of patient arrivals and patient flow between two comparable periods (from 10 February to 2 March) of 1999 and 2000. In between, a structural and staff reorganisation of ED was undertaken. The main reason for each patient remaining in ED was recorded and allocated to one of four groups: (1) factors related to ED itself; (2) factors related to ED-hospital interrelation; (3) factors related to hospital itself; and (4) factors related to neither ED nor hospital. The study measured the number of patients waiting to be seen and the waiting time to be seen as effectiveness markers, as well as the percentage of time that ED was overcrowded, as judged by numerical and functional criteria.

RESULTS

Effectiveness of ED was closely related with some ED related and hospital related factors. After the reorganisation, patients who remained in ED because of hospital related or non-ED-non-hospital related factors decreased. ED reorganisation reduced the number of patients waiting to be seen from 5.8 to 2.5 (p<0.001) and waiting time from 87 to 24 minutes (p<0.001). Before the reorganisation, 31% and 48% of the time was considered to be overcrowded in numerical and functional terms respectively. After the reorganisation, these figures were reduced to 8% and 15% respectively (p<0.001 for both).

CONCLUSIONS

ED effectiveness and overcrowding are not only determined by external pressure, but also by internal factors. Measurement of patient flow across ED has proved useful in detecting these factors and in being used to plan an ED reorganisation.

[Impact in the quality of health care and cost-effectiveness analysis of the reform of an emergency medicine service]

BACKGROUND

To determine the effects that the reform of an emergency department (ED) have on efficacy, health care quality and efficiency.

MATERIAL AND METHOD

Reforms consisted of 50% and 34% increases in structural and human resources, respectively. Roles of each ED member were redetermined, new assistance pathways were implemented, and the relationship between ED and the remaining hospital departments was reassessed. As efficacy markers, we determined the number of patients waiting to be attended (Pesp), the waiting time of patients to receive medical assistance (T(esp)),and the total waiting time of patients staying in the ED (T(total)). As health-care quality markers, we determined the percentage of patients leaving ED without having been visited by a physician(IPNV), the percentage of patients who were visited again (IPR),and the percentage of mortality (IPF). We also quantified the number of visits to the ED. All these data were obtained daily over 3 weeks, before (February 1999) and after (February 2000)the reforms. Effectiveness was estimated from the ratio P(total)/T(esp)(E1) and P(total)/P(esp) (E2). Costs were recorded for both periods and a cost-effectiveness analysis was performed to study the efficiency.

RESULTS

In 2000, the number of visits increased by +12% (CI 95%: 2% to 22%). Despite this increase, we observed an improvement of most efficacy and health-care quality markers after the ED reforms. E1 increased by 996% (CI 95%: 335% to 1,658%) and E2 increased by 186% (CI 95%: -23%to 395%). Cost-effectiveness analysis showed 70% (CI 95%: 33%to 107%) and 56% (CI 95%: 18% to 94%) increases regarding E1 and E2, respectively, after the reforms.

CONCLUSIONS

Providing ED with the necessary resources leads to an objective improvement of its efficacy and health-care quality and, consequently, the service and quality perceived by users improve. Despite the total cost increase after the ED reforms, efficiency also improves.
