International perspectives on emergency department crowding.

The maturation of emergency medicine (EM) as a specialty has coincided with dramatic increases in emergency department (ED) visit rates, both in the United States and around the world. ED crowding has become a public health problem where periodic supply and demand mismatches in ED and hospital resources cause long waiting times and delays in critical treatments. ED crowding has been associated with several negative clinical outcomes, including higher complication rates and mortality. This article describes emergency care systems and the extent of crowding across 15 countries outside of the United States: Australia, Canada, Denmark, Finland, France, Germany, Hong Kong, India, Iran, Italy, The Netherlands, Saudi Arabia, Catalonia (Spain), Sweden, and the United Kingdom. The authors are local emergency care leaders with knowledge of emergency care in their particular countries. Where available, data are provided about visit patterns in each country; however, for many of these countries, no national data are available on ED visits rates or crowding. For most of the countries included, there is both objective evidence of increases in ED visit rates and ED crowding and also subjective assessments of trends toward higher crowding in the ED. ED crowding appears to be worsening in many countries despite the presence of universal health coverage. Scandinavian countries with robust systems to manage acute care outside the ED do not report crowding is a major problem. The main cause for crowding identified by many authors is the boarding of admitted patients, similar to the United States. Many hospitals in these countries have implemented operational interventions to mitigate crowding in the ED, and some countries have imposed strict limits on ED length of stay (LOS), while others have no clear plan to mitigate crowding. An understanding of the causes and potential solutions implemented in these countries can provide a lens into how to mitigate ED crowding in the United States through health policy interventions and hospital operational changes.

The cost of a hip fracture. Estimates for 1,709 patients in Sweden.

We calculated the costs related to hip fractures and estimated the potential cost savings from preventing hip fractures. Subjects for this retrospective study were 1,709 hip fracture patients admitted for a primary hip fracture during 1992 in Stockholm, Sweden. Direct costs were compiled for the services of hospital orthopedics, hospital geriatrics, nursing homes, home for the elderly, group living, other acute hospital care, and municipal home help. The direct costs per patient during 1 year after a fracture amounted to about USD 40,000. The county council was responsible for 59% of the direct costs during 1 year after a hip fracture, while the remaining 41% were referred to the municipality. In the morbidity group, the potential cost savings per patient from preventing hip fractures was about USD 22,000.

Adverse Drug Reactions and Impaired Renal Function in Elderly Patients Admitted to the Emergency Department: A Retrospective Study

BackgroundAdverse drug reactions (ADRs) are common in elderly patients. There are various reasons for this, including age- and disease-related alterations in pharmacokinetics and pharmacodynamics as well as the common practice of polypharmacy. The decline in renal function in elderly patients may also predispose them to pharmacological ADRs (type A, augmented). Patients receiving home healthcare may be at even higher risk.ObjectivesTo study ADRs as a cause of acute hospital admissions in a defined cohort of elderly patients (aged ≥65 years) registered to receive home healthcare services, with special reference to impaired renal function as a possible risk factor.MethodsThis was a retrospective study of 154 elderly patients aged ≥65 years admitted to the emergency department of a university hospital in Stockholm, Sweden, in October–November 2002. Estimated creatinine clearance (eCLCR) was calculated from the Cockcroft-Gault formula, and estimated glomerular filtration rate (eGFR) by the Modification of Diet in Renal Disease (MDRD) equation. ADRs were defined according to WHO criteria. All medications administered to patients at admission and at discharge were collated. These and other data were collected from computerized hospital records.ResultsADRs were judged to contribute to or be the primary cause of hospitalization in 22 patients, i.e. 14% of 154 patients registered to receive home healthcare. Eleven of the 22 patients were women. All but one ADR were type A. Excessive doses or drugs unsuitable in renal insufficiency were present in seven patients in the ADR group compared with only four patients in the group without ADRs (p=0.0001). Patients with ADRs did not differ significantly from those without ADRs in relation to age, plasma creatinine, eCLCR, weight or number of drugs prescribed at admission. However, women with ADRs were significantly older than women without ADRs (mean±SD age 88.8±5.7 years vs 82.5±8.0 years, respectively; p=0.014) and had significantly lower mean±SD eCLCR values (25.5±10.8 and 37.1±17.1 mL/min, respectively; p=0.035). Median MDRD eGFR was significantly higher than median eCLCR (59 [range 6–172] mL/min/1.73 m2 vs 38 [range 5–117] mL/min, respectively; p=0.0001).ConclusionsIn elderly patients registered to receive home healthcare, 14% of hospital admissions were primarily caused by ADRs. One-third of these ADRs were related to impaired renal function, generally in very old women. These ADRs may be avoided by close monitoring of renal function and adjustments to pharmacotherapy (drug selection and dose), particularly in very elderly women.

Renal function estimations and dose recommendations for dabigatran, gabapentin and valaciclovir: a data simulation study focused on the elderly

Objectives The thrombin inhibitor dabigatran is mainly excreted by the kidneys. We investigated whether the recommended method for estimation of renal function used in the clinical trials, the Cockcroft-Gault (CGold) equation and the estimated glomerular filtration rate (eGFR) modification of diet in renal disease equation 4 (MDRD4), differ in elderly participants, resulting in erroneously higher dose recommendations of dabigatran, which might explain the serious, even fatal, bleeding reported. The renally excreted drugs gabapentin and valaciclovir were also included for comparison. Design A retrospective data simulation study. Participants Participants 65 years and older included in six different studies. Main outcome measure Estimated renal function by CG based on uncompensated (‘old Jaffe’ method) creatinine (CGold) or by MDRD4 based on standardised compensated P-creatinine traceable to isotope-dilution mass spectrometry, and the resulting doses. Results 790 participants (432 females), mean age (±SD) 77.6±5.7 years. Mean estimated creatinine clearance (eCrCl) by the CGold equation was 44.2±14.8 ml/min, versus eGFR 59.6±20.7 ml/min/1.73 m2 with MDRD4 (p<0.001), absolute median difference 13.5, 95% CI 12.9 to 14.2. MDRD4 gave a significantly higher mean dose (valaciclovir +21%, dabigatran +25% and gabapentin +37%) of all drugs (p<0.001). With MDRD4 58% of the women would be recommended a full dose of dabigatran compared with 18% if CGold is used. Conclusions MDRD4 would result in higher recommended doses of the three studied drugs to elderly participants compared with CG, particularly in women, and thus increased the risk of dose and concentration-dependent adverse reactions. It is important to know which method of estimation of renal function the Summary of Products Characteristics was based on, and use only that one when prescribing renally excreted drugs with narrow safety window. Doses based on recently developed methods for estimation of renal function may be associated with considerable risk of overtreatment in the elderly.

The key actor: a qualitative study of patient participation in the handover process in Europe

Background Patient safety experts have postulated that increasing patient participation in communications during patient handovers will improve the quality of patient transitions, and that this may reduce hospital readmissions. Choosing strategies that enhance patient safety through improved handovers requires better understanding of patient experiences and preferences for participation. Objective The aim of this paper is to explore the patients’ experiences and perspectives related to the handovers between their primary care providers and the inpatient hospital. Methods A qualitative secondary analysis was performed, based on individual and focus group patient interviews with 90 patients in five European countries. Results The analysis revealed three themes: patient positioning in the handover process; prerequisites for patient participation and patient preferences for the handover process. Patients’ participation ranged from being the key actor, to sharing the responsibility with healthcare professional(s), to being passive participants. For active participation patients required both personal and social resources as well as prerequisites such as information and respect. Some patients preferred to be the key actor in charge; others preferred their healthcare professionals to be the key actors in the handover. Conclusions Patients’ participation is related to the healthcare system, the activity of healthcare professionals’ and patients’ capacity for participation. Patients prefer a handover process where the responsibility is clear and unambiguous. Healthcare organisations need a clear and well-considered system of responsibility for handover processes, that takes into account the individual patients need of clarity, and support in relation to his/hers own recourses.

Hospital incident command system (HICS) performance in Iran; decision making during disasters

BackgroundHospitals are cornerstones for health care in a community and must continue to function in the face of a disaster. The Hospital Incident Command System (HICS) is a method by which the hospital operates when an emergency is declared. Hospitals are often ill equipped to evaluate the strengths and vulnerabilities of their own management systems before the occurrence of an actual disaster. The main objective of this study was to measure the decision making performance according to HICS job actions sheets using tabletop exercises.MethodsThis observational study was conducted between May 1st 2008 and August 31st 2009. Twenty three Iranian hospitals were included. A tabletop exercise was developed for each hospital which in turn was based on the highest probable risk. The job action sheets of the HICS were used as measurements of performance. Each indicator was considered as 1, 2 or 3 in accordance with the HICS. Fair performance was determined as < 40%; intermediate as 41-70%; high as 71-100% of the maximum score of 192. Descriptive statistics, T-test, and Univariate Analysis of Variance were used.ResultsNone of the participating hospitals had a hospital disaster management plan. The performance according to HICS was intermediate for 83% (n = 19) of the participating hospitals. No hospital had a high level of performance. The performance level for the individual sections was intermediate or fair, except for the logistic and finance sections which demonstrated a higher level of performance. The public hospitals had overall higher performances than university hospitals (P = 0.04).ConclusionsThe decision making performance in the Iranian hospitals, as measured during table top exercises and using the indicators proposed by HICS was intermediate to poor. In addition, this study demonstrates that the HICS job action sheets can be used as a template for measuring the hospital response. Simulations can be used to assess preparedness, but the correlation with outcome remains to be studied.

Beliefs and experiences can influence patient participation in handover between primary and secondary care—a qualitative study of patient perspectives

Background Communication between healthcare settings at patient transfers between primary and secondary care, ‘handover’, is a critical and risky process for patients. Patients’ views on their roles in these processes are often lacking despite the knowledge that patient participation contributes to enhanced safety and wellbeing. Objective This study aims to improve the knowledge and understanding of patients’ perspectives about their participation in handover. Methods Twenty-three Swedish patients with chronic diseases were individually interviewed about their experiences with handovers between three clinical microsystems: emergency room, emergency ward and primary healthcare centres. Data were analysed using inductive qualitative content analysis. Results Patients participated within the microsystems by exchanging information, and between microsystems by making contact with and conveying information to their next healthcare provider. Enablers for participation included positive encounters with providers, patient empowerment and beliefs about organisational factors. Patients’ trust in their providers, and providers’ attitudes were important factors in patients’ willingness to communicate. Patients who thought medical records access was shared across microsystems volunteered less information to their providers. Patients with experiences of non-effective handovers took more responsibility in the handover to ensure continuity of care. Conclusions Patients participate actively in handovers when they feel a need for involvement to ensure continuity of care, and are less active when they perceive that their contribution is unnecessary or not valued. In acute care settings with short hospital stays and less time to establish a trusting relationship between patients and their providers, discharge encounters may be important enablers for patient engagement in handovers. The advantages of a redundant handover process need to be considered.

Facilitators and obstacles in pre-hospital medical response to earthquakes: a qualitative study

BackgroundEarthquakes are renowned as being amongst the most dangerous and destructive types of natural disasters. Iran, a developing country in Asia, is prone to earthquakes and is ranked as one of the most vulnerable countries in the world in this respect. The medical response in disasters is accompanied by managerial, logistic, technical, and medical challenges being also the case in the Bam earthquake in Iran. Our objective was to explore the medical response to the Bam earthquake with specific emphasis on pre-hospital medical management during the first days.MethodsThe study was performed in 2008; an interview based qualitative study using content analysis. We conducted nineteen interviews with experts and managers responsible for responding to the Bam earthquake, including pre-hospital emergency medical services, the Red Crescent, and Universities of Medical Sciences. The selection of participants was determined by using a purposeful sampling method. Sample size was given by data saturation.ResultsThe pre-hospital medical service was divided into three categories; triage, emergency medical care and transportation, each category in turn was identified into facilitators and obstacles. The obstacles identified were absence of a structured disaster plan, absence of standardized medical teams, and shortage of resources. The army and skilled medical volunteers were identified as facilitators.ConclusionsThe most compelling, and at the same time amenable obstacle, was the lack of a disaster management plan. It was evident that implementing a comprehensive plan would not only save lives but decrease suffering and enable an effective praxis of the available resources at pre-hospital and hospital levels.

Postoperative mental impairment in hip fracture patients. A randomized study of reorientation measures in 223 patients

Mental impairment is a common and serious complication in geriatric surgery. We studied 223 hip fracture patients. They were over 64 years of age (mean 81), with no history of mental deterioration and acutely admitted to hospital from independent living conditions. They were randomized into two groups. One of these was subjected to reorientation measures during the perioperative phase, i.e., presurgery admission to the orthopedic ward, accompanied home visits during the hospital stay and access to reorientation devices--they received a large clock, calendar, radio, TV-set, telephone and were encouraged to wear their own clothing. Otherwise, there were no differences in the treatment given to the two groups. We used monitoring of cognitive function with the Short Portable Mental Status Questionnaire (SPMSQ) and a feedback program for evaluation of the treatment results. There was a low incidence of postoperative cognitive deterioration in both groups, compared with historical controls. However, no difference in mental status was noted when we compared the two groups. The conclusion is that attributes were less important than the psychological environment for postoperative mental deterioration. The mean total continuous hospitalization (transfers between departments and hospitals included) in the reorientation group was 22 (95% CI: 17-43) days, the corresponding figures for the controls were 30 (14-29) days.
