Association between access to primary care and unplanned emergency department return visits among patients 75 years and older.

OBJECTIVE: To identify factors associated with unplanned return visits to the emergency department (ED) among the population aged 75 years and older. Moreover, it aims to determine the association between patients' access to primary care and unplanned return visits. DESIGN: Data were collected from structured interviews, administrative databases, and medical charts at the index visits, and follow-up telephone calls were made at 3 months. SETTING: Emergency departments of the 3 tertiary care hospitals in Montréal, Que. PARTICIPANTS: Community-dwelling patients aged 75 years and older. MAIN OUTCOME MEASURES: Zero-inflated negative binomial regression analysis was conducted of unplanned return visits within 3 months. Rate ratios (RRs) and odds ratios (ORs) with 95% CIs are presented. RESULTS: During the study period, 4577 patients were identified, 2303 were recruited, and 1998 were retained for the analysis. Among the analysis sample, 33% were 85 and older, 34% lived alone, and 91% had a family physician. Before their ED visits, 16% of patients attempted to contact their family physicians. More than half of the patients reported having difficulty seeing their physicians for urgent problems, more than 40% had difficulty speaking with their family physicians by telephone, and more than one-third had difficulty booking appointments for new health problems. Within 3 months, 562 patients (28%) had made 894 return visits. Factors associated with a lower return visit rate included age 85 years and older (RR=0.80; 95% CI 0.67 to 0.96), less severe triage score (RR=0.83; 95% CI 0.74 to 0.92), and hospitalization at the index visit (RR=0.76; 95% CI 0.64 to 0.90). Factors that resulted in a higher return visit rate were difficulty booking appointments for new problems with their family physicians (RR=1.19; 95% CI 1.01 to 1.41), having had ED visits within the previous 6 months (RR=1.47; 95% CI 1.28 to 1.68), and higher Charlson comorbidity index scores (RR=1.06; 95% CI 1.01 to 1.11). Having had ED visits within the previous 6 months (OR=2.11; 95% CI 1.27 to 3.49), having a higher Charlson comorbidity index score (OR=1.41; 95% CI 1.19 to 1.68), and having received community care services (OR=3.00; 95% CI 0.95 to 9.53) also increased the odds of return visits. CONCLUSION: Although most people 75 years and older have a family physician, problems still exist in terms of timely access. Unplanned return visits to the ED are associated with having more comorbidities, having had previous ED visits, having already received community services, and having difficulty booking appointments with family physicians for new problems.

Frailty and adverse outcomes in older adults being discharged from the emergency department: A prospective cohort study.

BACKGROUND: A growing number of frail older adults are treated in the emergency department (ED) and discharged home. There is an unmet need to identify older adults that are predisposed to functional decline and repeat ED visits so as to target them with proactive interventions. METHODS: A prospective cohort study was conducted in patients 75 years or older who were being discharged from the ED. The objective was to test the value of frailty screening tests, namely 5-meter gait speed and handgrip strength, to predict repeat ED visits at 1 and 6 months and functional decline at 1 month using multivariable logistic regression. RESULTS: After excluding 7 patients lost to follow-up, 150 patients were available for analysis. The mean age was 81.1 ± 4.9 years with 51% females, 13% arriving by ambulance, and 67% having at least two comorbid conditions. At ED discharge, 41% of patients were found to have slow gait speed, whereas 23% had weak handgrip strength. After adjustment, only slow gait speed was independently associated with functional decline at 1 month (odds ratio [OR] 1.39 per 0.1 meters/second decrement, 95% confidence interval [CI], 1.12 to 1.72) and repeat ED visits at 6 months (OR 1.20 per 0.1 meters/second decrement, 95% CI, 1.01 to 1.42). CONCLUSIONS: Gait speed can be feasibly measured at the time of ED discharge to identify frail older adults at risk for early functional decline and subsequent return to the ED. Conversely, grip strength was not found to be associated with functional decline or ED visits.

Patient Needs, Required Level of Care, and Reasons Delaying Hospital Discharge for Nonacute Patients Occupying Acute Hospital Beds.

This study aims to determine the proportion of nonacute patients occupying acute care beds and to describe their needs, the appropriate level of alternative care, and reasons preventing discharge. Data from 952 patients hospitalized in an acute care unit for 30 days were obtained from their medical charts and by consulting with the medical team at two tertiary teaching hospitals. Among them, 333 (35%) were determined nonacute on day 30 of hospitalization. According to the Appropriateness Evaluation Protocol (AEP), 55% had no medical, nursing, or patient needs. Among nonacute patients with AEP needs, 88% were related to nursing/life-support services and 12% related to patient condition factors. Regarding alternative level of care, 186 (56%) were waiting for out-of-hospital resources, of which 36% were waiting for palliative care, 33% for long-term care, 18% for rehabilitation, and 12% for home care. For the remaining 147 (44%) nonacute patients, the alternative resources remained undetermined although acute care was no longer required. Main reasons preventing discharge included unavailability of alternative resources, ongoing assessment to determine appropriate resources, ongoing process with community care, and family/patient education/counseling. Available subacute facilities and community-based care would liberate acute care beds and facilitate their appropriate use.

Characteristics and Needs of Psychiatric Patients With Prolonged Hospital Stay.

OBJECTIVE: To describe the characteristics and needs prior to, on admission, during the first month in hospital, at the thirtieth day of hospitalization and posthospital discharge of psychiatric patients occupying acute beds. METHODS: This prospective observational study was conducted in 2 tertiary care hospitals. Adult patients hospitalized on a psychiatric unit for 30 days were identified. Data was collected from their medical charts and interviews with their health care team. The categorization of acute and nonacute status at day 30 was based on the health care professional's evaluation. Descriptive and univariate analyses were performed. RESULTS: A total of 262 patients were identified (mean age 45 years), 66% lived at home and 11% were homeless. More than one-half were cognitively impaired and a few had special medical needs. Ninety-seven per cent had been admitted from the emergency department. At day 30, 81% of patients required acute care, while 19% (95% CI 15% to 24%) occupied an acute care bed, despite the resolution of their acute condition. The main reason preventing discharge of nonacute patients was the difficulty or inability to find appropriate resources that met patients' needs. As for patients who required acute care, the most common psychiatric issues were delusions or hallucinations (34%), inability to take medications independently (23.6%), and inadequate control of aggression or impulsivity (16.5%). CONCLUSIONS: Prevention of the discharge of nonacute patients is largely due to the difficulty in finding appropriate resources that meet patients' needs. Improved access to community and subacute care resources could potentially facilitate the hospital discharge of psychiatric nonacute patients.

Hospital stay on acute care units for non-acute reasons: Effects of patient pre-hospitalization and admission factors.

This study identifies patient risk factors present prior to an acute hospitalization that are associated with occupying acute care beds for non-acute reasons on the 30th day of a hospitalization. Data from 952 adult patients were obtained, among which 333 (35%) were evaluated as non-acute on their 30th day. Inability to move in and out of the bed, cognitive impairment, receiving home or community healthcare services prior to hospitalization, unavailable family resources, a secondary diagnosis within the mental and behavioural category, and age ≥75 years were found to increase the risk of occupying acute care beds for non-acute reasons, while patients with a feeding tube were less likely to be non-acute at day 30.

Detection and correction of prescription errors by an emergency department pharmacy service.

OBJECTIVES: Emergency departments (EDs) are recognized as a high-risk setting for prescription errors. Pharmacist involvement may be important in reviewing prescriptions to identify and correct errors. The objectives of this study were to describe the frequency and type of prescription errors detected by pharmacists in EDs, determine the proportion of errors that could be corrected, and identify factors associated with prescription errors. METHODS: This prospective observational study was conducted in a tertiary care teaching ED on 25 consecutive weekdays. Pharmacists reviewed all documented prescriptions and flagged and corrected errors for patients in the ED. We collected information on patient demographics, details on prescription errors, and the pharmacists' recommendations. RESULTS: A total of 3,136 ED prescriptions were reviewed. The proportion of prescriptions in which a pharmacist identified an error was 3.2% (99 of 3,136; 95% confidence interval [CI] 2.5-3.8). The types of identified errors were wrong dose (28 of 99, 28.3%), incomplete prescription (27 of 99, 27.3%), wrong frequency (15 of 99, 15.2%), wrong drug (11 of 99, 11.1%), wrong route (1 of 99, 1.0%), and other (17 of 99, 17.2%). The pharmacy service intervened and corrected 78 (78 of 99, 78.8%) errors. Factors associated with prescription errors were patient age over 65 (odds ratio [OR] 2.34; 95% CI 1.32-4.13), prescriptions with more than one medication (OR 5.03; 95% CI 2.54-9.96), and those written by emergency medicine residents compared to attending emergency physicians (OR 2.21, 95% CI 1.18-4.14). CONCLUSIONS: Pharmacists in a tertiary ED are able to correct the majority of prescriptions in which they find errors. Errors are more likely to be identified in prescriptions written for older patients, those containing multiple medication orders, and those prescribed by emergency residents.

Development of the Canadian Emergency Department Diagnosis Shortlist.

OBJECTIVE: Managers of emergency departments (EDs), governments and researchers would benefit from reliable data sets that characterize use of EDs. Although Canadian ED lists for chief complaints and triage acuity exist, no such list exists for diagnosis classification. This study was aimed at developing a standardized Canadian Emergency Department Diagnosis Shortlist (CED-DxS), as a subset of the full International Classification of Diseases, 10th revision, with Canadian Enhancement (ICD-10-CA). METHODS: Emergency physicians from across Canada participated in the revision of the ICD-10-CA through 2 rounds of the modified Delphi method. We randomly assigned chapters from the ICD-10-CA (approximately 3000 diagnoses) to reviewers, who rated the importance of including each diagnosis in the ED-specific diagnosis list. If 80% or more of the reviewers agreed on the importance of a diagnosis, it was retained for the final revision. The retained diagnoses were further aggregated and adjusted, thus creating the CED-DxS. RESULTS: Of the 83 reviewers, 76% were emergency medicine (EM)-trained physicians with an average of 12 years of experience in EM, and 92% were affiliated with a university teaching hospital. The modified Delphi process and further adjustments resulted in the creation of the CED-DxS, containing 837 items. The chapter with the largest number of retained diagnoses was injury and poisoning (n = 292), followed by gastrointestinal (n = 59), musculoskeletal (n = 55) and infectious disease (n = 42). Chapters with the lowest number retained were neoplasm (n = 18) and pregnancy (n = 12). CONCLUSION: We report the creation of the uniform CED-DxS, tailored for Canadian EDs. The addition of ED diagnoses to existing standardized parameters for the ED will contribute to homogeneity of data across the country.

Markers of overcrowding in a pediatric emergency department.

OBJECTIVES: The objective of this study was to identify markers of overcrowding in pediatric emergency departments (PEDs) according to expert opinion and then to use statistical methods to further explore the underlying construct of overcrowding. METHODS: A cross-sectional survey of all PED directors (n = 12) and pediatric emergency medicine fellowship program directors (n = 10) across Canada was conducted to elicit expert opinion on relevant markers of emergency department (ED) crowding. The list of markers was reduced to those specific to the ED for which data could be extracted from one tertiary care PED from an existing computerized patient tracking system. Data representing 2,190 consecutive shifts and 138,361 patient visits were collected between April 2005 and March 2007. Common factor analysis (CFA) was used to determine the underlying factors that best represented overcrowding as determined by markers identified by experts in pediatric emergency medicine RESULTS: The main markers of overcrowding identified by the survey included measures of patient volume (25%), ED operational processes (55%), and delays in transferring patients to inpatient beds (13%). Data collected on 41 markers were retained for the CFA. The results of the CFA indicated that the largest portion of variation in the data (48%) was accounted for by markers describing patient volumes and flow through the ED. Measures of admission delays accounted for a smaller proportion of variability (9%). CONCLUSIONS: The results suggest that for this tertiary PED, markers of ED operational processes and patient volume may be more relevant for determination of overcrowding than markers reflecting delays in transferring patients to inpatient beds. This study provides a foundation for further research on markers of overcrowding specific to the pediatric setting.

Effective synthesized/preappraised evidence formats in emergency medicine and the use of supplemental knowledge translation techniques.

Most clinicians, and especially emergency physicians, are increasingly faced with the need for valid and reliable evidence upon which to base practice decisions in a timely fashion. Despite the accumulation of synthesized evidence in emergency medicine over the past decade, knowledge gaps still exist between what is known and what is practiced. In many cases, this failure in knowledge uptake relates to barriers in uptake as well as the difficulty of translating evidence from research to the bedside. Preappraised evidence syntheses represent a potential partial solution to these problems by providing condensed summaries of the large volume of scientific literature in our field. The participants in this workshop examined the availability, utility, and impact of preappraised evidence and examined innovative ways to translate this knowledge into practice. In addition, the workshop participants also explored more globally all knowledge translation methods that are distinct from clinical pathways (e.g., audit and feedback, academic detailing, reminders, and local opinion leaders). These are initiatives that are instituted at the level of a particular hospital or with respect to a certain condition, and emergency physicians need to understand their definition and application. Overall, the recommendations arising from this workshop have the potential to alter future emergency care in important ways.

Impact of a standardized communication system on continuity of care between family physicians and the emergency department.

OBJECTIVE: It has been suggested that continuity of care is hampered because of the lack of communication between emergency departments (EDs) and primary care providers. A web-based, standardized communication system (SCS) that enables family physicians (FPs) to visualize information regarding their patients' ED visits was developed. This paper aims to evaluate the impact of this SCS on continuity of care. METHODS: We conducted an open, 4-period crossover, cluster-randomized controlled trial of 23 FP practices. During the intervention phase, FPs received detailed reports via SCS, while in the control phase they received mailed copies of the ED notes. Continuity of care was evaluated with a web questionnaire completed by FPs 21 days after the ED visit. The primary measures of continuity of care were knowledge of ED visit (quality and quantity), patient management and follow-up rate. RESULTS: We analyzed a total of 2022 ED visits (1048 intervention and 974 control). The intervention group received information regarding the ED visit more often (odds ratio [OR] 3.14, 95% confidence interval [CI] 2.6-3.79), found the information more useful (OR 5.1, 95% CI 3.49-7.46), possessed a better knowledge of the ED visit (OR 6.28, 95% CI 5.12-7.71), felt they could better manage patients (OR 2.46, 95% CI 2.02-2.99) and initiated actions more often following receipt of information (OR 1.62, 95% CI 1.36-1.93). However, there was no significant difference in the follow-up rate at FPs offices (OR 1.25, 95% CI 0.97-1.61). CONCLUSION: The use of SCS between an ED and FPs led to significant improvements in continuity of care by increasing the usefulness of transferred information and by improving FPs' perceived patient knowledge and patient management.

The in-hospital interval: a description of EMT time spent in the emergency department.

OBJECTIVE: We conducted a time-motion study of emergency medical technician (EMT) flow in an urban, academic emergency department (ED). Our objective was to describe the activity of the EMTs during their time in the ED. Secondary objectives included the association of time of day, age, and triage code with the various time intervals. METHODS: In this descriptive study, we combined information from two databases: prospectively collected time-motion data of EMTs presenting to one ED and an electronically collected prehospital call database of time data. The pretriage, triage, and posttriage time intervals were calculated, as well as total time spent in the ED as a proportion of total call time. Mean times with 95% confidence intervals (CIs) were reported. Analysis of variance was performed to examine the associations of time of day, age, and triage code with time intervals. RESULTS: Data were available for 152 calls. The mean pretriage interval was 8.79 (95% CI, 7.55-10.04) minutes, the mean triage interval was 5.14 (95% CI, 4.49-5.79) minutes, and the mean posttriage interval was 31.33 (95% CI, 29.08-33.58) minutes. The proportion of the total call time that was spent in the ED was 45%. Subgroup analysis showed significant differences only between total time spent in the ED in the 7:30-10:00 AM period as compared with the other periods. CONCLUSIONS: More time was spent in the pretriage and posttriage intervals as compared with the triage interval. Further time-motion studies in the ED will be necessary to plan interventions aimed at decreasing the time spent in-hospital by EMTs.

Impact of an electronic link between the emergency department and family physicians: a randomized controlled trial.

BACKGROUND: Electronic information exchange is believed to improve efficiency and reduce resource utilization. We developed a Web-based standardized communication system (SCS) that enables family physicians to receive detailed reports of their patients' care in the emergency department. We sought to determine the impact of the SCS on measures of resource utilization in the emergency department and family physician offices. METHODS: We used an open 4-period crossover cluster-randomized controlled design. During 2 separate 10-week intervention phases, family physicians received detailed reports of their patients' emergency department visits over the Internet, and in the alternating control phases they received a 1-page copy of the emergency department notes by mail. The primary outcome was the number of repeat visits to the emergency department within 14 days of the initial visit. Secondary outcomes included duplication of test and specialty consultation requests by the emergency and family physician. Outcomes were measured using the hospital database and questionnaires sent to the family physicians. RESULTS: A total of 2022 patient visits to the emergency department from 23 practices were used in the study. Use of the SCS failed to reduce the number of repeat visits to the emergency department within 14 days (odds ratio [OR] 1.10, 95% confidence interval [CI] 0.8-1.51) and 28 days (OR 1.01, 95% CI 0.8-1.27). There was no significant duplication of requests for diagnostic tests between the emergency and family physician during the intervention and control phases (24 v. 22, p = 0.93), but there was significantly greater duplication in specialty consultation requests in the intervention phase than in the control phase (20 v. 8, p = 0.049). INTERPRETATION: An electronic link between emergency and family physicians did not result in a significant reduction in resource utilization at either service point. Investments in improved electronic information exchange between emergency departments and family physician offices may not be substantiated by a reduction in resource utilization.

Emergency physician recognition of adverse drug-related events in elder patients presenting to an emergency department.

OBJECTIVES: The authors examined the ability of emergency physicians (EPs) to recognize adverse drug-related events (ADREs) in elder patients presenting to the emergency department (ED). METHODS: This was a prospective observational study of patients at least 65 years of age who presented to the ED. ADREs were identified using a validated, standardized scoring system. EP recognition of ADREs was assessed through physician interview and subsequent chart review. RESULTS: A total of 161 patients were enrolled in the study. Thirty-seven ADREs were identified, which occurred in 26 patients (16.2%; 95% confidence interval [CI] = 10.5% to 22.0%). The treating EPs recognized 51.2% (95% CI = 35.2% to 67.4%) of all ADREs. There was better recognition of those ADREs related to the patient's chief complaint (91%; 95% CI = 74.1% to 100%) as compared with recognition of ADREs that were not associated with the chief complaint (32.1%; 95% CI = 14.8% to 49%). EPs recognized six of seven severe ADREs (85.7%), 13 of 23 moderate ADREs (56.5%; 95% CI = 36.8% to 77%), and none of the mild ADREs. Recognition of ADREs varied with medication class. CONCLUSIONS: EP performance was superior at identifying severe ADREs relating to the patients' chief complaints. However, EP performance was suboptimal with respect to identifying ADREs of lower severity, having missed a significant number of ADREs of moderate severity as well as ones unrelated to the patients' chief complaints. ADRE detection methods need to be developed for the ED to aid EPs in detecting those ADREs that are most likely to be missed.

Successful implementation of a combined pneumococcal and influenza vaccination program in a Canadian emergency department.

OBJECTIVES: To determine the proportion of patients vaccinated with pneumococcal (PVAX) and influenza (IVAX) vaccines under an emergency department (ED) vaccination program, that would not otherwise have been vaccinated by other primary care resources. METHODS: This prospective cohort study was performed in a tertiary care academic centre. A questionnaire was administered to all consenting ED patients who met screening eligibility criteria to receive either IVAX or PVAX. Eligible unvaccinated patients who did not plan on receiving vaccination elsewhere were offered one or both of the vaccines and, if agreeable, were immunized in the ED. RESULTS: During the 4-week study period, 754 patients (36% of all presenting ED patients) were eligible for vaccination with one or both vaccines. Of these 525 (70%) consented to participate in the study and completed a questionnaire. Of the 525 participants, 289 (55% of IVAX eligible patients; 95% confidence interval [CI], 51%-59%) were unvaccinated against influenza that year and did not plan on being vaccinated elsewhere and 277 (60% of PVAX eligible patients; 95% CI, 56%-64%) were unvaccinated against pneumococcus and did not plan on being vaccinated elsewhere. IVAX was administered to 187 patients (65% penetration; 95% CI, 59%-70%), and PVAX was administered to 165 patients (60% penetration; 95% CI, 54%-65%). Overall vaccine penetration was 46% (95% CI, 42%-50%) in the study participants and 32% (95% CI, 29%-35%) for the entire ED screened and eligible group. Reasons for vaccination refusal included concerns about benefit, side effects, and the desire to discuss vaccination with their primary care physician. CONCLUSIONS: An ED-based program can result in the vaccination of a significant proportion of patients eligible for IVAX and/or PVAX who would otherwise likely go unprotected.

Nonurgent emergency department patient characteristics and barriers to primary care.

OBJECTIVE: Nonurgent (NU) emergency department (ED) use is at the forefront of medico-political agendas, and diversion of NU patients has been entertained as a management strategy. Before policy changes are implemented, this population should be better understood with respect to their characteristics and reasons for not presenting to primary care providers (PCPs) instead of EDs. This study compares NU with urgent and semiurgent (USU) patients and describes the NU patients' reasons for not seeking care with a PCP before presenting to the ED. METHODS: This was a secondary analysis from a cross-sectional study with sequential sampling in the EDs of five Quebec tertiary care hospitals (October 19, 1999, to May 26, 2000). Data on medical history, social support, awareness and utilization of health care, ED visits, referrals, activities of daily living, and sociodemographics were obtained. The NU group included patients with triage code 5 and the USU group included patients with triage codes 2, 3, and 4 using the Canadian Triage and Acuity Scale. Patient characteristics were structured into the Andersen behavioral model for health care utilization. RESULTS: Of 2,348 patients approached, 1,783 patients (77%) were eligible and agreed to participate. NU patients (n = 454) were younger than USU patients (n = 1,329) (mean age, 43 [SD +/- 18.1] vs. 49 [SD +/- 20.1] years). Patients in the NU group had better health (number of prior conditions, 3.1 vs. 3.9), were less likely to arrive by ambulance (5% vs. 22%), and were less often admitted from the ED (4% vs. 24%). While 70% of NU compared with 75% of USU patients were followed up by a PCP, only 22% of NU and 27% of USU patients sought PCP care before presenting to the ED. The reasons given by NU patients for not seeking PCP care were accessibility (32%), perception of need (22%), referral/follow-up to the ED (20%), familiarity with the ED (11%), trust of the ED (7%), and no reason (7%). CONCLUSIONS: NU ED patients are different from USU patients and have multiple reasons for not seeking primary care before going to the ED. This may help explain why various diversion strategies have been unsuccessful and indicate that a multifaceted approach may be better suited to this group of patients. The design of new interventions, however, will benefit from further research that clarifies the impact of NU patients on the health care system.

An emergency department-based nurse discharge coordinator for elder patients: does it make a difference?

OBJECTIVES: To evaluate the impact of an emergency department (ED)-based nurse discharge plan coordinator (NDPC) on unscheduled return visits within 14 days of discharge, satisfaction with discharge recommendations, adherence with discharge instructions, and perception of well-being of elder patients discharged from the ED. METHODS: Patients aged 75 years and older discharged from the ED of the Sir Mortimer B. Davis-Jewish General Hospital were recruited in a pre/post study. During the pre (control) phase, study patients (n = 905) received standard discharge care. Patients in the post (intervention) phase (n = 819) received the intervention of an ED-based NDPC. The intervention included patient education, coordination of appointments, patient education, telephone follow-up, and access to the NDPC for up to seven days following discharge. RESULTS: Patients in the two groups were similar with respect to gender and age. However, the patients managed by the ED NDPC appeared to be, at baseline, less autonomous, frailer, and sicker. The unadjusted relative risk for unscheduled return visits within 14 days of discharge was 0.79 (95% confidence interval [95% CI] = 0.62 to 1.02). A relative risk reduction of 27% (95% CI = 0% to 44%) for unscheduled return visits was observed for up to eight days postdischarge, and a relative risk reduction of 19% (95% CI = -2% to 36%) for unscheduled return visits was observed for up to 14 days postdischarge. Significant increases in satisfaction with the clarity of discharge information and perceived well-being were also noted. CONCLUSIONS: An ED-based NDPC, dedicated specifically to the discharge planning care of elder patients, reduces the proportion of unscheduled ED return visits and facilitates the transition from ED back home and into the community health care network.

Impact of ambulance transportation on resource use in the emergency department.

OBJECTIVE: To determine how ambulance transportation is associated with resource use in the emergency department (ED). METHODS: A retrospective administrative database review of patient visits to a Montreal tertiary care hospital ED in one year (April 2000-March 2001). Measures of resource use included ED length of stay, admission to the hospital, and whether consultations and radiology/imaging tests (excluding plain-film x-rays) were ordered from the ED. RESULTS: During the study period, 39,674 patients made 59,142 visits to the ED. Ambulance transportation was used for 15.6% of these ED visits. Compared with non-ambulance visits, ambulance visits were more likely to be made by older patients (mean age: 68 vs. 47 years), to be made by females (59% vs. 55%), to have a greater triage urgency score (mean on 1-5 scale, with 1 most urgent: 2.7 vs. 3.9), and to occur after office hours, 5 PM to 9 AM (47% vs. 43%). Ambulance visits were also more likely than non-ambulance visits to result in: a longer length of stay (mean: 13.3 hours [95% CI = 13.0 to 13.6] vs. 5.9 [95% CI = 5.8 to 6.0]), hospital admission (40% vs. 10%) (odds ratio [OR]: 5.94 [95% CI = 5.59 to 6.33]), consultations (56% vs. 20%) (OR: 5.15 [95% = 4.86 to 5.45]), and radiology/imaging tests (20% vs. 12%) (OR: 1.93 [95% CI = 1.81 to 2.07]). In multivariate models that adjusted for the effects of age, gender, triage urgency, and temporal factors, ambulance transportation maintained its association with greater resource use. CONCLUSIONS: This preliminary study indicates that patients arriving at the ED by ambulance use significantly more resources than their walk-in counterparts.

Intervention to decrease emergency department crowding: does it have an effect on return visits and hospital readmissions?

STUDY OBJECTIVES: We evaluate the effect of a multifaceted intervention to decrease emergency department crowding on the incidence of return visits to the ED or a hospital ward. The intervention included increased emergency physician coverage, the designation of physician coordinators, and new hospital policies regarding laboratory, consultation, and admission procedures. METHODS: The incidence of return visits within 7 days of discharge was estimated in samples from 2 populations (ie, patients discharged from the ED and patients discharged from the hospital) and during a 12-month period before and a 12-month period after the implementation of the intervention. Return visits were categorized into the following groups: (1) scheduled or not and (2) related or not to initial visit. Logistic regression was used in subsamples to assess the effect of the intervention while controlling for potential confounders. By using information from the provincial medical services database, variation between the periods before and after implementation of the intervention in the incidence of return visits to any ED was compared between the study hospital and 2 external control hospitals. RESULTS: No difference was found in the incidence of return visits between the periods before and after implementation of the intervention, either for patients discharged from the ED (all returns: 11.0% versus 12.4%, 95% confidence interval on difference [CID] -1.5% to 4.3%; unscheduled-related returns: 6.5% versus 5.8%, 95% CID -2.8% to 1.6%) or the hospital (all returns: 6.8% versus 6.6%, 95% CID -2.5% to 2.1%; unscheduled-related returns: 4.2% versus 4.0%, 95% CID -2.0% to 1.7%). This lack of effect remained even after controlling for potential confounders. Variation between the periods before and after implementation of the intervention in the incidence of return to any ED was similar in the 3 hospitals examined. CONCLUSION: Our successful hospital intervention to decrease crowding reduced the mean length of stay for patients discharged from the ED from 13.8 to 5.9 hours, without resulting in increased return visits to the ED or hospital readmission.
