Objective
The objective of this study was to establish the effectiveness of interventions to reduce frequent emergency department (ED) use among a general adult high ED-use population.Methods
Systematic review of the literature from 1950-January 2015. Studies were included if they: had a control group (controlled trials or comparative cohort studies), were set in an ED or acute care facility, and examined the impact of an intervention to reduce frequent ED use in a general adult population. Studies reporting non-original data or focused on a specific patient population were excluded. Study design, patient population, intervention, the frequency of ED visits, and costs of frequent ED use and/or interventions were extracted and narratively synthesized.Results
Among 17 included articles, three intervention categories were identified: case management (n = 12), individualized care plans (n = 3), and information sharing (n = 2). Ten studies examining case management reported reductions in mean (-0.66 to -37) or median (-0.1 to -20) number of ED visits after 12-months; one study reported an increase in mean ED visits (+2.79); and one reported no change. Of these, 6 studies also reported reduced hospital costs. Only 1 study evaluating individualized care plans examined ED utilization and found no change in median ED visits post-intervention. Costs following individualized care plans were also only evaluated in 1 study, which reported savings in hospital costs of $742/patient. Evidence was mixed regarding information sharing: 1 study reported no change in mean ED visits and did not examine costs; whereas the other reported a decrease in mean ED visits (-16.9) and ED cost savings of $15,513/patient.Conclusions
The impact of all three frequent-user interventions was modest. Case management had the most rigorous evidence base, yielded moderate cost savings, but with variable reductions in ED use. Future studies evaluating non-traditional interventions, tailoring to patient subgroups or socio-cultural contexts, are warranted. 相似文献2.

Objective: The patterns of emergency department (ED) visits in patients with diabetes are not well understood. The Emergency Department Diabetes Rapid-referral Program (EDRP) allows direct booking of ED patients presenting with urgent diabetes needs into a diabetes specialty clinic within 1 day of ED discharge. The objective of this secondary analysis was to examine characteristics of patients with diabetes who have frequent ED visits and determine reasons for revisits.Methods: A single-center analysis was conducted comparing patients referred to the EDRP (n = 420) to historical unexposed controls (n = 791). The primary outcome was the proportion of patients in each frequency group of ED revisits (none, 1 to 3 [infrequent], 4 to 10 [frequent], or >10 [superfrequent]) in the year after the ED index visit. Secondary outcomes were hospitalization rates and International Classification of Diseases–Ninth Revision (ICD-9) diagnoses at ED revisits.Results: Superfrequent users, responsible for >20% of total ED visits, made up small but not significantly different proportions of EDRP and control populations, 3.6% and 5.2%, respectively. Superfrequent groups had lower hospital admission rates at ED revisits compared to frequent groups. Mental health disorders (including substance abuse) were the primary, secondary, or tertiary ICD-9 codes in 30.6% (95% confidence interval [CI], 27.7% to 33.5%) and 6.6% (95% CI, 5.1% to 8.2%) in the superfrequent and infrequent groups, respectively.Conclusion: Direct access to diabetes specialty care from the ED is effective in reducing ED recidivism but not amongst a small subgroup of superfrequent ED users. This group was more likely to have mental health disorders recorded at ED revisits, suggesting that more comprehensive approaches are needed for this population.Abbreviations: EDRP = Emergency Department Diabetes Rapid-referral Program; ED = emergency department; HbA1c = hemoglobin A1c; ICD-9 = International Classification of Diseases–Ninth Revision 相似文献

Background
Little is known about patients who frequently visit the emergency department (ED) for acute exacerbation of chronic obstructive pulmonary disease (AECOPD). We aimed to quantify the proportion and characteristics of patients with frequent ED visits for AECOPD and associated healthcare utilization.Methods
We conducted a retrospective cohort study of adults aged ≥40 years with at least one ED visit for AECOPD between 2010 and 2011, derived from population-based all-payer data of State ED and Inpatient Databases for two large and diverse states: California and Florida. Outcome measures were frequency of ED visits for AECOPD, 30-day ED revisits, subsequent hospitalizations, near-fatal events (AECOPD involving mechanical ventilation), and charges for both ED and inpatient services (available only for Florida) during the year after the first ED visit.Results
The analytic cohort comprised 98,280 unique patients with 154,736 ED visits for AECOPD. During the 1-year period, 29.4% (95% CI, 29.1%-29.7%) of the patients had two or more (frequent) visits, accounting for 55.2% (95% CI, 54.9%-55.4%) of all ED visits for AECOPD. In the multivariable model, significant predictors of frequent ED visits were age 55–74 years (vs. 40–54 years), male sex, non-Hispanic white or black race, Medicaid insurance (vs. private), and lower median household income (all P < 0.001). At the visit-level, 12.3% of ED visits for AECOPD were 30-day revisit events (95% CI, 12.1%-12.4%). Additionally, 62.8% of ED visits for AECOPD (95% CI, 62.6%-63.0%) resulted in a hospitalization; patients with frequent ED visits comprised 55.5% (95% CI, 55.2%-55.8%) of all hospitalizations. Furthermore, 7.3% (95% CI, 7.3%-7.5%) of ED visits for AECOPD led to a near-fatal event; patients with frequent ED visits accounted for 64.4% (95% CI, 63.5%-65.3%) of all near-fatal events. Total charges for AECOPD were $1.94 billion (95% CI, $1.90-1.97 billion) in Florida; patients with frequent ED visits accounted for $1.07 billion (95% CI, $1.04-1.09 billion).Conclusions
In this large cohort study, we found that 29% had frequent ED visits for AECOPD and that lower socioeconomic status was significantly associated with a higher frequency of ED visits. Individuals with frequent ED visits for AECOPD accounted for a substantial amount of healthcare utilization and financial burden. 相似文献4.
Introduction
Sickle cell anemia has many sequelae that result in emergency department (ED) use, but a minority of patients with sickle cell disease are frequent utilizers and make up the majority of ED visits. If patients who are likely to be frequent ED can be identified in steady state, they can be treated with disease modifying agents in an attempt to reduce ED use frequency. We sought to identify steady state markers for frequent ED use.Methods
We identified all patients with SS/Sβ0 seen at our facilities in 2012. Health care utilization over the entire year was calculated and ED visit numbers categorized as either 0–1, 2–5, or 6 or more visits a year. Steady state and acutely active laboratory parameters were collected and analyzed using analysis of variance models and odds ratios.Results
432 adult sickle cell patients were identified, ages 18–87, 54% female, and 38% had been prescribed hydroxyurea. Of the 432 patients,192 had 0–1 visits in the year, 144 had 2–5 visits in the year, and 96 had >6 visits for a total of 2259 visits. Those who had >6 visits accounted for 1750 (77%) of the total visits for the year. When steady state laboratory markers were examined, each additional 50x109/L platelets was associated with 22% greater risk (p < .001); each 1x109/L of WBC was associated with 11% greater risk (p = .003), and each 1g/dL Hb was associated with 23% lower risk (p = .007) of >6 ED visits/year. We did not observe a relationship between baseline HbF, LDH or reticulocyte count with >6 ED visits.Conclusion
Patients with elevated white blood cell counts, elevated platelet counts, and low hemoglobin levels exhibited higher risk for frequent ED utilization and could be candidates for early and aggressive therapy with disease modifying agents. 相似文献5.

BACKGROUND:Little is known about the risk of death among people who visit emergency departments frequently for alcohol-related reasons, including whether mortality risk increases with increasing frequency of visits. Our primary objective was to describe the sociodemographic and clinical characteristics of this high-risk population and examine their 1-year overall mortality, premature mortality and cause of death as a function of emergency department visit frequency in Ontario, Canada.METHODS:We conducted a population-based retrospective cohort study using linked health administrative data (Jan. 1, 2010, to Dec. 31, 2016) in Ontario for people aged 16–105 years who made at least 2 emergency department visits for mental or behavioural disorders due to alcohol within 1 year. We subdivided the cohort based on visit frequency (2, 3 or 4, or ≥ 5). The primary outcome was 1-year mortality, adjusted for age, sex, income, rural residence and presence of comorbidities. We examined premature mortality using years of potential life lost (YPLL).RESULTS:Of the 25 813 people included in the cohort, 17 020 (65.9%) had 2 emergency department visits within 1 year, 5704 (22.1%) had 3 or 4 visits, and 3089 (12.0%) had 5 or more visits. Males, people aged 45–64 years, and those living in urban centres and lower-income neighbourhoods were more likely to have 3 or 4 visits, or 5 or more visits. The all-cause 1-year mortality rate was 5.4% overall, ranging from 4.7% among patients with 2 visits to 8.8% among those with 5 or more visits. Death due to external causes (e.g., suicide, accidents) was most common. The adjusted mortality rate was 38% higher for patients with 5 or more visits than for those with 2 visits (adjusted hazard ratio 1.38, 95% confidence interval 1.19–1.59). Among 25 298 people aged 16–74 years, this represented 30 607 YPLL.INTERPRETATION:We observed a high mortality rate among relatively young, mostly urban, lower-income people with frequent emergency department visits for alcohol-related reasons. These visits are opportunities for intervention in a high-risk population to reduce a substantial mortality burden.Alcohol is a leading driver of morbidity and mortality worldwide.1 An estimated 3 million deaths in 2016 — 5% of all global deaths — were attributable to alcohol consumption.2 The 2016 Global Burden of Disease Study showed that alcohol was the single greatest risk factor for ill health worldwide among people aged 15–49 years.3 In Canada, hospital admissions for alcohol-attributable conditions out-number those for myocardial infarction.4 Alcohol-related harms cost Canadians about $14.6 billion annually, with $3.3 billion in health care costs.5In addition to the societal impact of mental and behavioural disorders due to alcohol (henceforth referred to as alcohol-related) — mainly acute intoxication and withdrawal — these disorders are common reasons for emergency department visits.6,7 Data from the United States and Canada, furthermore, suggest that alcohol-related emergency department visits have increased in recent years.8,9 For example, a study in Ontario showed that, between 2003 and 2016, the age-standardized rates of alcohol-attributable emergency department visits increased by 86.5% in women and 53.2% in men.8 People who visit emergency departments frequently for alcohol-related reasons have high levels of comorbidity and social disadvantage,10,11 and represent a readily identifiable patient population for whom interventions to address unmet social and health care needs could be developed.12–14 A systematic review suggested that screening and brief intervention for alcohol-related problems in the emergency department is a promising approach for reducing problematic alcohol consumption.13Despite this, little is known about the risk of death, a key outcome for health system performance, among people who use emergency departments frequently for alcohol-related reasons, including whether mortality risk increases with increasing frequency of visits. To address this gap, our primary objective was to describe the sociodemographic and clinical characteristics of this high-risk population and examine their 1-year overall mortality, premature mortality and cause of death as a function of emergency department visit frequency in Ontario, the most populous Canadian province.15 相似文献

Background
Frequent painful vaso-occlusive crises (VOCs) were associated with mortality in the Cooperative Study of Sickle Cell Disease (CSSCD) over twenty years ago. Modern therapies for sickle cell anemia (SCA) like hydroxyurea are believed to have improved overall patient survival. The current study sought to determine the relevance of the association between more frequent VOCs and death and its relative impact upon overall mortality compared to other known risk factors in a contemporary adult SCA cohort.Methods
Two hundred sixty four SCA adults were assigned into two groups based on patient reported outcomes for emergency department (ED) visits or hospitalizations for painful VOC treatment during the 12 months prior to evaluation.Results
Higher baseline hematocrit (p = 0.0008), ferritin (p = 0.005), and HDL cholesterol (p = 0.01) were independently associated with 1 or more painful VOCs requiring an ED visit or hospitalization for acute pain. During a median follow-up of 5 years, mortality was higher in the ED visit/hospitalization group (relative risk [RR] 2.68, 95% CI 1.1-6.5, p = 0.03). Higher tricuspid regurgitatant jet velocity (TRV) (RR 2.41, 95% CI 1.5-3.9, p < 0.0001), elevated ferritin (RR 4.00, 95% CI 1.8-9.0, p = 0.001) and lower glomerular filtration rate (RR=2.73, 95% CI 1.6-4.6, p < 0.0001) were also independent risk factors for mortality.Conclusions
Severe painful VOCs remain a marker for SCA disease severity and premature mortality in a modern cohort along with other known risk factors for death including high TRV, high ferritin and lower renal function. The number of patient reported pain crises requiring healthcare utilization is an easily obtained outcome that could help to identify high risk patients for disease modifying therapies.Trial Registration

We examined how emergency department (ED) visits for potentially preventable, mental health, and other diagnoses were related to same-day access and provider continuity in primary care using administrative data from 71,296 patients in 22 VHA clinics over a three-year period. ED visits were categorized as non-emergent; primary care treatable; preventable; not preventable; or mental health-related. We conducted multi-level regression models adjusted for patient and clinic factors. More same-day access significantly predicted fewer non-emergent and primary care treatable ED visits while continuity was not significantly related to any type of ED visit. Neither measure was related to ED visits for mental health problems. 相似文献

ObjectiveTo describe the burden of illness, healthcare utilization, and costs associated with Cushing disease (CD), a rare disorder resulting from adrenocorticotropic hormone-secreting pituitary tumors, in commercially insured patients in the U.S.MethodsPatients with CD were identified in 2010 in the IMS Health PharMetrics and Truven Health Analytics MarketScan claims databases. Because there is no diagnosis code for CD, patients were identified with a claim for Cushing syndrome and either benign pituitary adenoma or hypophysectomy. We estimated total sand CD-related utilization and costs using pharmacy and medical claims.ResultsWe identified 685 CD patients (81% female; mean age, 41.7 years; mean Charlson comorbidity index, 1.6; mean number of chronic conditions, 4.2); 30.5% of the patients had diabetes, 22.5% had psychiatric disturbances, 21% had infections, 8.6% had osteoporosis, 8% had cardiovascular disease/stroke, 5.5% had kidney stones, and 0.7% had compression fracture of a vertebra. Patients had a mean of 19.8 office visits per year; 38.4% had inpatient hospitalizations and 34.2% visited the emergency department (ED). Patients had a mean of 3.2 CD-related office visits per year; 26.9% had CD-related hospitalizations, 0.9% had CD-related ED visits, and 36.8% had CD treatments. Mean annual total costs were $34,992 (pharmacy, $3,597; medical costs, $31,395). CD-related costs accounted for $14,310 of total costs (CD treatment costs, $9,353; other CD-related costs, $4,957).ConclusionCD patients have a high burden of illness. Among CD patients in this study, 30.5% had diabetes, 22.5% had psychiatric disturbances, 21% had infections, 8.6% had osteoporosis, 8% had cardiovascular disease/ stroke, and 5.5% had kidney stones. Patients had 19.8 office visits per year, and > 34% of patients were hospitalized. Mean total cost of care was approximately $35,000 per year. (Endocr Pract. 2015;21:77-86) 相似文献

Study objective
To assess the association of patient and organisational factors with emergency department length of stay (ED-LOS) in elderly ED patients (226565 years old) and in younger patients (<65 years old).Methods
A retrospective cohort study of internal medicine patients visiting the emergency department between September 1st 2010 and August 31st 2011 was performed. All emergency department visits by internal medicine patients 226565 years old and a random sample of internal medicine patients <65 years old were included. Organisational factors were defined as non-medical factors. ED-LOS is defined as the time between ED arrival and ED discharge or admission. Prolonged ED-LOS is defined as ≥75th percentile of ED-LOS in the study population, which was 208 minutes.Results
Data on 1782 emergency department visits by elderly patients and 597 emergency department visits by younger patients were analysed. Prolonged ED-LOS in elderly patients was associated with three organisational factors: >1 consultation during the emergency department visit (odds ratio (OR) 3.2, 95% confidence interval (CI) 2.3–4.3), a higher number of diagnostic tests (OR 1.2, 95% CI 1.16–1.33) and evaluation by a medical student or non-trainee resident compared with a medical specialist (OR 4.2, 95% CI 2.0–8.8 and OR 2.3, 95% CI 1.4–3.9). In younger patients, prolonged ED-LOS was associated with >1 consultation (OR 2.6, 95% CI 1.4–4.6). Factors associated with shorter ED-LOS were arrival during nights or weekends as well as a high urgency level in elderly patients and self-referral in younger patients.Conclusion
Organisational factors, such as a higher number of consultations and tests in the emergency department and a lower seniority of the physician, were the main aspects associated with prolonged ED-LOS in elderly patients. Optimisation of the organisation and coordination of emergency care is important to accommodate the needs of the continuously growing number of elderly patients in a better way. 相似文献11.

ObjectivesIdentifying frequent users’ (≥3 admissions/year) associated factors in an emergency department (ED), using a comprehensive geriatric assessment (CGA), describing the characteristics of patients over 65 years of age.MethodsA cross-sectional study was performed between August 2017 and June 2018 in an ED in Lisbon, Portugal. CGA was applied and completed with clinical records. Clinical, functional, mental and social scores were created based in Portuguese Society of Internal Medicine, and a statistical model was developed.ResultsCGA was applied to 426 patients over 64 years old in an ED. The mean age was 79.3, 84.7% had multimorbidity. 51.2%, 75.6%, and 40% had dependence on basic, instrumental, and walking activities, respectively. 52% had depressive symptoms, 65.7% had cognitive impairment, 63% were undernourished/at risk for malnutrition. 33.1% were socially at risk. Polypharmacy was present with a use on average of 6.5 drugs daily. Social, clinical, functional, and mental scores were unfavourable in 48.6%, 79.6%, 54.9% and 83.1% of the population, respectively. There were 2.7 hospital admissions/year and 39.9% were frequent ED users (≥3/year). The logistic regression model was weak, but showed that patients with polypharmacy, elevated Charlson Comorbidity index and an impairment nutritional status presented higher risk of being frequent users.ConclusionsThis study showed that 97.1% of patients had needs that would justify an interventional care plan. This intervention should be extended to primary care and nursing homes. While not providing a robust model, our study has indicated nutritional problems, polypharmacy, and an elevated Charlson index as the features with more weight in frequent users’ admissions. 相似文献

Background
Many people living with HIV access healthcare systems through the emergency department (ED), and increased ED use may be indicative of disenfranchisement with primary HIV care, under-managed comorbid disease, or coincide with use of other healthcare resources. The goal of this study was to investigate ED use by HIV-infected prisoners transitioning to communities.Methods
We evaluated ED use by 151 HIV-infected released prisoners who were enrolled in a randomized controlled trial of directly administered versus self-administered antiretroviral therapy in Connecticut. Primary outcomes were quantity and type of ED visits and correlates of ED use were evaluated with multivariate models by Poisson regression.Results
In the 12 months post-release, there were 227 unique ED contacts made by 85/151 (56%) subjects. ED visits were primarily for acute febrile syndromes (32.6%) or pain (20.3%), followed by substance use issues (19.4%), trauma (18%), mental illness (11%), and social access issues (4.4%). Compared to those not utilizing the ED, users were more likely to be white, older, and unmarried, with less trust in their physician and poorer perceived physical health but greater social support. In multivariate models, ED use was correlated with moderate to severe depression (IRR = 1.80), being temporarily housed (IRR = 0.54), and alcohol addiction severity (IRR = 0.21) but not any surrogates of HIV severity.Conclusions
EDs are frequent sources of care after prison-release with visits often reflective of social and psychiatric instability. Future interventions should attempt to fill resource gaps, engage released prisoners in continuous HIV care, and address these substantial needs. 相似文献13.

Despite historical gender bias against female physicians, few studies have investigated patients’ physician gender preference in the emergency department (ED) setting. We sought to determine if there is an association between ED patient demographics and physician gender preference. We surveyed patients presenting to an ED to determine association between patient demographics and patient physician gender preference for five ED situations: 1) ‘routine’ visit, 2) emergency visit, 3) ‘sensitive’ medical visit, 4) minor surgical/‘procedural’ visit, and 5) ‘bad news’ delivery. A total of 200 ED patients were surveyed. The majority of ED patients reported no physician gender preference for ‘routine’ visits (89.5 percent), ‘emergent’ visits (89 percent), ‘sensitive’ medical visits (59 percent), ‘procedural’ visits (89 percent) or when receiving ‘bad news’ (82 percent). In the setting of ‘routine’ visits and ‘sensitive’ medical visits, there was a propensity for same-sex physician preference. 相似文献

The objective of this case-control study was to investigate the risk of cardiovascular disease (CVD) following non-steroidal anti-inflammatory drug (NSAID) use in patients with ankylosing spondylitis (AS). A total of 10,763 new AS patients were identified from the National Taiwan Health Insurance claims database during the period from 1997 to 2008. In all, 421 AS patients with CVD were recruited as cases, and up to 2-fold as many sex- and age-matched controls were selected. Logistic regression models were used to estimate the odds ratio (OR) between NSAID use and CVD incidence. The medication possession rate (MPR) was used to evaluate NSAID exposure during the study period. AS patients had increased risk of CVD (OR, 1.68; 95% confidence interval (CI), 1.57 to 1.80). Among frequent (MPR≥80%) COX II users, the risks for all types of CVD were ten times lower than those among non-users at 24 months (OR, 0.08; 95% CI, 0.01 to 0.92). Among frequent NSAID users, the risks of major adverse cardiac event (MACE) were significantly lower at 12 months (OR, 0.23; 95% CI, 0.07 to 0.76)—a trend showing that longer exposure correlated with lower risk. Regarding non-frequent NSAID users (MPR<80%), short-term exposure did carry higher risk (for 6 months: OR, 1.41; 95% CI, 1.07 to 1.86), but after 12 months, the risk no longer existed. We conclude that long-term frequent use of NSAIDs might protect AS patients from CVD; however, NSAIDs still carried higher short-term risk in the non-frequent users. 相似文献

Unselected population-based nationwide studies on the excess mortality of individuals with severe mental disorders are scarce with regard to several important causes of death. Using comprehensive register data, we set out to examine excess mortality and its trends among patients with severe mental disorders compared to the total population. Patients aged 25–74 and hospitalised with severe mental disorders in 1990–2010 in Finland were identified using the national hospital discharge register and linked individually to population register data on mortality and demographics. We studied mortality in the period 1996–2010 among patients with psychotic disorders, psychoactive substance use disorders, and mood disorders by several causes of death. In addition to all-cause mortality, we examined mortality amenable to health care interventions, ischaemic heart disease mortality, disease mortality, and alcohol-related mortality. Patients with severe mental disorders had a clearly higher mortality rate than the total population throughout the study period regardless of cause of death, with the exception of alcohol-related mortality among male patients with psychotic disorders without comorbidity with substance use disorders. The all-cause mortality rate ratio of patients with psychotic disorders compared to the total population was 3.48 (95% confidence interval 2.98–4.06) among men and 3.75 (95% CI 3.08–4.55) among women in the period 2008–10. The corresponding rate ratio of patients with psychoactive substance use disorders was 5.33 (95% CI 4.87–5.82) among men and 7.54 (95% CI 6.30–9.03) among women. Overall, the mortality of the total population and patients with severe mental disorders decreased between 1996 and 2010. However, the mortality rate ratio of patients with psychotic disorders and patients with psychoactive substance use disorders compared to the total population increased in general during the study period. Exceptions were alcohol-related mortality among patients with psychoactive substance use disorders and female patients with psychotic disorders, as well as amenable mortality among male patients with psychotic disorders. The mortality rate ratio of persons with mood disorders compared to the total population decreased. The markedly high mortality amenable to health care intervention among patients with severe mental disorders found in our study suggests indirectly that they may receive poorer quality somatic care. The results highlight the challenges in co-ordinating mental and somatic health services. 相似文献

Background
In 2000, Ontario, Canada, initiated a universal influenza immunization program (UIIP) to provide free influenza vaccines for the entire population aged 6 mo or older. Influenza immunization increased more rapidly in younger age groups in Ontario compared to other Canadian provinces, which all maintained targeted immunization programs. We evaluated the effect of Ontario''s UIIP on influenza-associated mortality, hospitalizations, emergency department (ED) use, and visits to doctors'' offices.Methods and Findings
Mortality and hospitalization data from 1997 to 2004 for all ten Canadian provinces were obtained from national datasets. Physician billing claims for visits to EDs and doctors'' offices were obtained from provincial administrative datasets for four provinces with comprehensive data. Since outcomes coded as influenza are known to underestimate the true burden of influenza, we studied more broadly defined conditions. Hospitalizations, ED use, doctors'' office visits for pneumonia and influenza, and all-cause mortality from 1997 to 2004 were modelled using Poisson regression, controlling for age, sex, province, influenza surveillance data, and temporal trends, and used to estimate the expected baseline outcome rates in the absence of influenza activity. The primary outcome was then defined as influenza-associated events, or the difference between the observed events and the expected baseline events. Changes in influenza-associated outcome rates before and after UIIP introduction in Ontario were compared to the corresponding changes in other provinces. After UIIP introduction, influenza-associated mortality decreased more in Ontario (relative rate [RR] = 0.26) than in other provinces (RR = 0.43) (ratio of RRs = 0.61, p = 0.002). Similar differences between Ontario and other provinces were observed for influenza-associated hospitalizations (RR = 0.25 versus 0.44, ratio of RRs = 0.58, p < 0.001), ED use (RR = 0.31 versus 0.69, ratio of RRs = 0.45, p < 0.001), and doctors'' office visits (RR = 0.21 versus 0.52, ratio of RRs = 0.41, p < 0.001). Sensitivity analyses were carried out to assess consistency, specificity, and the presence of a dose-response relationship. Limitations of this study include the ecological study design, the nonspecific outcomes, difficulty in modeling baseline events, data quality and availability, and the inability to control for potentially important confounders.Conclusions
Compared to targeted programs in other provinces, introduction of universal vaccination in Ontario in 2000 was associated with relative reductions in influenza-associated mortality and health care use. The results of this large-scale natural experiment suggest that universal vaccination may be an effective public health measure for reducing the annual burden of influenza. 相似文献18.

Background:
Frequent users of health care services are a relatively small group of patients who account for a disproportionately large amount of health care utilization. We conducted a meta-analysis of the effectiveness of interventions to improve the coordination of care to reduce health care utilization in this patient group.Methods:
We searched MEDLINE, Embase and the Cochrane Library from inception until May 2014 for randomized clinical trials (RCTs) assessing quality improvement strategies for the coordination of care of frequent users of the health care system. Articles were screened, and data abstracted and appraised for quality by 2 reviewers, independently. Random effects meta-analyses were conducted.Results:
We identified 36 RCTs and 14 companion reports (total 7494 patients). Significantly fewer patients in the intervention group than in the control group were admitted to hospital (relative risk [RR] 0.81, 95% confidence interval [CI] 0.72–0.91). In subgroup analyses, a similar effect was observed among patients with chronic medical conditions other than mental illness, but not among patients with mental illness. In addition, significantly fewer patients 65 years and older in the intervention group than in the control group visited emergency departments (RR 0.69, 95% CI 0.54–0.89).Interpretation:
We found that quality improvement strategies for coordination of care reduced hospital admissions among patients with chronic conditions other than mental illness and reduced emergency department visits among older patients. Our results may help clinicians and policy-makers reduce utilization through the use of strategies that target the system (team changes, case management) and the patient (promotion of self-management).Frequent users of health care services represent a relatively small group of patients who account for a disproportionately large amount of health care utilization, including emergency department visits,1,2 hospital admissions and clinic visits. These patients are often of low socioeconomic status,3,4 have multiple medical, psychiatric and social disorders5,6 and have a high mortality.7 Frequent use of the health care system contributes to longer wait times and affects the quality of care.4,8Disproportionate use of health care services by a segment of the population has been identified as a challenge in many countries, including Canada.9–12 To encourage less resource-intensive care for frequent users, many efforts have been implemented. Some of these interventions, for example, have been designed specifically to transition health care utilization away from the hospital to other settings, such as community-based clinics.13Much of the literature has focused on frequent users of emergency departments, with less focus on their use of the health care system in general. One systematic review identified a number of studies that assessed the effect of various interventions, including care coordination.14 The authors concluded that case management and multidisciplinary teams were likely effective interventions to reduce emergency department visits.Emergency department visits typically represent only a fraction of the cost burden on the health care system. There is a need to understand the impact of interventions aimed at reducing overall health care utilization, including hospital admissions. We conducted a systematic review and meta-analysis of the effectiveness of quality improvement strategies for care coordination for patients who are frequent users of the health care system. 相似文献19.

In 2010, ischemic heart disease was the leading cause of disability-adjusted life-years (DALYs) worldwide. More specially, the prevalence of acute myocardial infarctions (AMI) is increasing in the aged population as mortality decreases; South Korea is no exception. This study aims to examine the economic burden of AMI in the Korean population between 2007 and 2012. AMI-related costs were assessed from a societal perspective. A prevalence-based cost-of-illness framework was used for this analysis. The subjects included all South Koreans with AMI-related ICD-10 codes (I21, I22, I23, I25.0, and I25.1). Data on direct (medical and non-medical) costs and indirect (productivity loss due to AMI-associated morbidity and mortality) costs were collected from the Korean National Health Insurance Service’s claims data. The human capital approach was used to calculate indirect costs. The total estimated cost of AMI in 2012 was $1,177,649,323 USD. The majority (52%) of this amount was made up of medical costs, followed by productivity losses due to mortality and morbidity (42% of annual cost). Although the total cost declined by approximately 18% compared to 2007 ($1,427,643,854 USD), the cost of AMI in the over 60 age group amounted to 47% of the total cost of AMI in 2012. AMI led to a high economic burden in 2012. This study, which identified not only the size, but also the trends of AMI-related costs, will provide information to evaluate effects of governmental health projects and the effective allocation of public research funds. 相似文献
