Epidemiology and outcomes of out-of-hospital cardiac arrest in Rochester, New York.

OBJECTIVE: To characterize out-of-hospital cardiac arrest (OHCA) and factors that affect survival in a medium sized city that uses system status management for dispatch. METHODS: A retrospective cohort study of all adult OHCA patients treated by EMS between 1998 and 2001 was conducted using Utstein definitions. The primary endpoint was 1-year survival. RESULTS: Of the 1177 patients who experienced OHCA during the study period, 539 (46%) met inclusion criteria. Age ranged from 18 to 98 years (median 67). The median call-response interval was 5 min (range 0-21), and 93% were 9 min or less. There was no significant difference in the median call-response intervals between call location zip (Post) codes (p=0.07). Twenty percent of experienced ROSC (95% CI 17-23), 7% survived more than 30 days (95% CI 5-9%), and 5% survived to 1 year (95% CI 3-7%). In bivariate analysis, first rhythm and bystander CPR affected survival to 1 year. There was no significant difference in survival between male (4%) and female (7%), black (4%) and white (6%), or witnessed (7%) and unwitnessed arrest (4%). Logistic regression identified younger age, CPR initiated by bystander (19%) or first responder (41%), and presenting rhythm of VF/VT (32%) as factors associated with survival to 1 year. CONCLUSIONS: This study finds a 5% survival to 1 year among OHCA patients in Rochester, NY. A presenting rhythm of VF/VT and bystander CPR were associated with increased survival.

A comprehensive framework for determining the cost of an emergency medical services system.

To determine the cost of an emergency medical services (EMS) system, researchers, policymakers, and EMS providers need a framework with which to identify the components of the system that must be included in any cost calculations. Such a framework will allow for cost comparisons across studies, communities, and interventions. The objective of this article is to present an EMS cost framework. This framework was developed by a consensus panel after analysis of existing peer-reviewed and non-peer-reviewed resources, as well as independent expert input. The components of the framework include administrative overhead, bystander response, communications, equipment, human resources, information systems, medical oversight, physical plant, training, and vehicles. There is no hierarchical rank to these components; they are all necessary. Within each component, there are subcomponents that must be considered. This framework can be used to standardize the calculation of EMS system costs to a community. Standardizing the calculation of EMS cost will allow for comparisons of costs between studies, communities, and interventions.

Economic value of out-of-hospital emergency care: a structured literature review.

STUDY OBJECTIVE: The evaluation of the impact of out-of-hospital emergency care is a relatively new research focus. As such, there is a compelling need to determine how finite health care resources should be used in this setting. The objective of this study is to conduct a structured review of published economic evaluations of out-of-hospital emergency care to assess its economic value. METHODS: A structured literature search and structured review of articles pertaining to the economic value of out-of-hospital care was performed. The bibliographic database MEDLINE was searched for pertinent English-language articles published between 1966 and 2003. The search used the medical subject headings "emergency medical services" and "emergency medical technician" and was limited to the subheading "economics" and crossed with the medical subject heading "economics." The titles generated by this search were systematically reviewed and limited by topic. Abstracts from the identified titles were reviewed to select a final set of pertinent articles. These articles were further limited based on explicit inclusion and exclusion criteria. Authors used a previously published structured evaluation tool to review the final set of identified articles for quality and content. RESULTS: The initial MEDLINE search identified 3,533 citations. From this set, 535 potentially relevant abstracts were reviewed. From the abstract review, 46 articles were identified, along with an additional 14 from searching the secondary references. Of these 60 articles, 32 met the review inclusion criteria and were subjected to a full structured review. These studies predominantly addressed the cost of cardiac arrest (n=13, 41%), major trauma (n=8, 25%), and emergency medical services treatment in general (n=8, 25%). Only 14 studies considered the costs and consequences of competing alternatives. Of these, 2 were cost-benefit and 12 were cost-effectiveness evaluations. Two of the 14 studies met all 10 criteria for high-quality economic evaluation, whereas 2 others met none. CONCLUSION: There is a paucity of out-of-hospital care literature that addresses cost and economic value. The extant literature is limited in scope, poor in quality, and evaluates small subsets of out-of-hospital emergency care costs. Favorable cost-effectiveness has not been firmly established for most aspects of out-of-hospital emergency care.

Cardiac arrests in skilled nursing facilities: continuing room for improvement?

OBJECTIVES: To characterize the care received by skilled nursing facility (SNF/NF) patients suffering cardiac arrest and to evaluate the outcome of SNF/NF patients experiencing cardiac arrest. DESIGN: A retrospective analysis of an existing cardiac arrest registry to characterize SNF/NF cardiac arrest patients and to compare them to community-dwelling cardiac arrest patients was performed. SETTING: The study took place in Rochester, NY, an urban city in upstate New York with approximately 220,000 residents. PARTICIPANTS: All patients for whom emergency medical services (EMS) assistance was requested via the 911 system and who were treated for cardiac arrest between January 1998 and December 2001 were included. MEASUREMENTS: Demographic characteristics such as age, gender, race; clinical characteristics and interventions such as cardiopulmonary resuscitation (CPR), defibrillation, initial cardiac rhythm, and call response interval; outcomes measures such as return of spontaneous circulation and 1-year survival were obtained. RESULTS: Forty-two (8%) of cardiac arrest patients resided in an SNF/NF. Sixteen (38%) of the events were witnessed arrests. Only 28 (67%) patients received CPR and none were defibrillated prior to EMS arrival. One (2%) patient was alive 1 year after the event, a survival rate similar to the community-dwelling population (5%). CONCLUSION: SNF/NF patients suffering cardiac arrest often did not receive CPR or defibrillation while awaiting EMS arrival. SNF/NF patients suffering cardiac arrest have a very low survival rate, similar to the community-dwelling population. The impact of not providing CPR and defibrillation on the survival rate is unclear, but needs to be evaluated prior to any decisions regarding the medical futility of resuscitating SNF/NF patients.

An emergency medical services program to promote the health of older adults.

OBJECTIVES: To evaluate the feasibility and effect of an emergency medical services (EMS) program that screened, educated, and referred older adults with unmet needs. DESIGN: A cluster sample design evaluation of an intervention conducted by EMS in one of two communities. SETTING: Two rural communities in upstate New York. PARTICIPANTS: Two hundred fifty-eight intervention-group and 143 control-group community-dwelling older adults receiving emergency care from participating EMS agencies between February 2004 and June 2005. INTERVENTION: EMS providers screened intervention group patients to identify those at risk for falls, influenza, and pneumococcal infections and provided patients educational materials. Patients' physicians were notified of screening results to provide interventions. Control group patients were provided usual care. MEASUREMENTS: Variables included patient demographic and clinical characteristics, the proportion of eligible patients screened, patient risk during EMS care and 14 days later, and patient recollection of receiving educational materials and conversations with physicians regarding needs. RESULTS: Follow-up was successful in 245 (61%) patients. Approximately 80% of intervention-group patients were successfully screened for each item. No differences were identified for characteristics collected at the time of EMS care, but a notable number of patients were at risk for each item. No differences existed between the control or intervention group for process measures such as recollection of receiving educational materials. For outcome measures, only an improvement in pneumococcal vaccination levels was found. CONCLUSION: EMS screening of older adults during emergency responses is feasible, but a simple intervention of providing educational materials to patients during emergency responses and faxing notifications to physicians appears insufficient to address patients' needs.

Description and evaluation of a pilot physician-directed emergency medical services diversion control program.

OBJECTIVES: To describe the characteristics and feasibility of a physician-directed ambulance destination-control program to reduce emergency department (ED) overcrowding, as measured by hospital ambulance diversion hours. METHODS: This controlled trial took place in Rochester, New York and included a university hospital and a university-affiliated community hospital. During July 2003, emergency medical services (EMS) providers were asked to call an EMS destination-control physician for patients requesting transport to either hospital. The destination-control physician determined the optimal patient destination by using patient and system variables as well as EMS providers' and patients' input. Program process measures were evaluated to characterize the program. Administrative data were reviewed to compare system characteristics between the intervention program month and a control month. RESULTS: During the intervention month, 2,708 patients were transported to the participating hospitals. EMS providers contacted the destination-control physician for 1,866 (69%) patients. The original destination was changed for 253 (14%) patients. Reasons for redirecting patients included system needs, patient needs, physician affiliation, recent ED or hospital care, patient wishes, and primary care physician wishes. During the intervention month, EMS diversion decreased 190 (41%) hours at the university hospital and 62 (61%) hours at the community hospital, as compared with the control month. CONCLUSIONS: A voluntary, physician-directed destination-control program that directs EMS units to the ED most able to provide appropriate and timely care is feasible. Patients were redirected to maximize continuity of care and optimally use available emergency health care resources. This type of program may be effective in reducing overcrowding.

Accuracy of mild traumatic brain injury case ascertainment using ICD-9 codes.

OBJECTIVES: To determine the accuracy of mild traumatic brain injury (TBI) case ascertainment using International Classification of Diseases, 9th Revision, Clinical Modification (ICD-9-CM) codes proposed by the Centers for Disease Control and Prevention (CDC) in a 2003 Report to Congress. METHODS: This was a prospective cohort study of all patients presenting to an urban academic emergency department (ED) over six months in 2003. A real-time clinical assessment of mild TBI was compared with the ICD-9 codes assigned after ED or hospital discharge for a determination of sensitivity and specificity. RESULTS: Of the 35,096 patients presenting to the ED, 516 had clinically defined mild TBI and 1,000 were assigned one or more of the mild TBI ICD-9 codes proposed by the CDC. The sensitivity of these codes was 45.9% (95% confidence interval [95% CI] = 41.3% to 50.2%) with a specificity of 97.8% (95% CI = 97.6% to 97.9%). CONCLUSIONS: The identification of mild TBI patients using retrospectively assigned ICD-9 codes appears to be inaccurate. These codes are associated with a significant number of false-positive and false-negative code assignments. Mild TBI incidence and prevalence estimates using these codes should be interpreted with caution. ICD-9 codes should not replace a clinical assessment for mild TBI when accurate case ascertainment is required.

Parent opinions about universal influenza vaccination for infants and toddlers.

BACKGROUND: Parent and caregiver opinions on the feasibility of routine influenza vaccinations for infants and toddlers are unknown. OBJECTIVE: To assess among English-speaking caregivers of children aged 6 to 23 months opinions about childhood influenza vaccination and potential knowledge, attitudinal, and demographic factors that might influence such opinions. METHODS: A structured, interviewer-administered survey of knowledge, attitudes, and beliefs about the influenza vaccine among parents and caregivers of children at the ambulatory pediatric clinic or the pediatric emergency department of a large tertiary care teaching hospital. The dependent measure was respondents' expressed intentions to have their eligible children immunized against influenza in the upcoming season. RESULTS: We interviewed 153 caregivers. One hundred nineteen (78%) expressed intent to immunize. Safety was reported by 70 respondents (46%) as their most important concern, followed by the belief that the influenza vaccine could itself cause influenza (31 respondents, 20%). Respondents who believed that influenza was serious, that the influenza vaccine does not cause disease, or that all babies should be immunized had greater intent to immunize than those who did not (85%, 87%, and 96% vs 66%, 66%, and 49%, respectively). Those who believed that vomiting was a symptom of influenza, who did not name any vaccine adverse effect, or who had high school or lower educational levels also had greater intent to immunize (87%, 89%, and 83% vs 66%, 69%, and 69%, respectively). CONCLUSION: Knowledge, attitudes, beliefs, and educational levels each had an independent influence on parents' intentions to vaccinate the child, whereas demographic factors other than education did not.

Identification of out-of-hospital cardiac arrest clusters using a geographic information system.

OBJECTIVES: To locate all out-of-hospital cardiac arrests (OHCAs) in Rochester, New York, and identify clusters of OHCAs, as well as clusters of patients who did not receive bystander cardiopulmonary resuscitation (CPR), in order to identify locations that may benefit from prevention efforts. METHODS: The locations of all adult OHCAs of cardiac etiology occurring in the study city over a four-year period were plotted on a map using ArcGIS. Location information was obtained from the emergency medical services (EMS) medical record and included street address and zip code. Descriptive data related to patient treatment and transport were also abstracted. Kernel analysis was used to identify areas with the highest density of OHCAs. Census-defined block groups were used to calculate OHCA incidence in order to determine the effect of population density. Patients with OHCAs who did not receive bystander CPR were selected and kernel analysis was repeated to identify areas with the highest density of no bystander CPR. RESULTS: A total of 537 OHCAs that met the inclusion criteria occurred during the study period. Ninety-four percent had sufficient location information to be plotted. Two clusters of OHCAs were identified. One cluster covered two block groups that were found to have the highest incidence of OHCA in the city (incidence: 142 [95% CI = 42 to 241] and 105 [95% CI = 35 to 175] per 10,000 people). EMS providers or first responders started CPR (i.e., no bystander CPR) for 80% of patients. Kernel analysis revealed three areas with a high density of no bystander CPR; these areas coincided with the OHCA cluster sites. Cluster communities were found to have a lower median household income and a larger percentage of people living below the poverty level, to have more residents of African American race, and to have more residents without a high school diploma compared with the city's population in general. CONCLUSIONS: Out-of-hospital cardiac arrest can be plotted by geographic location. Clusters of OHCAs can be identified, which could be used to guide resource allocation. Clusters of OHCAs in which the patients did not receive bystander CPR can also be identified and could be used to direct educational programs. Census data can be superimposed on this information to identify characteristics of cluster locations and were used to demonstrate that the identified clusters were not simply the result of population density.

The time first-response fire fighters have to initiate care in a midsize city.

The objective of this study was to determine whether simultaneously dispatched first-response firefighters (fire) arrive before transporting EMS providers (ambulance) and the amount of time fire has on scene to initiate care. Fire and ambulance dispatch records were obtained for all 9-1-1 responses from four 1-month intervals. Only incidents to which both agencies had been simultaneously dispatched were included. Response time for each agency was determined by subtracting the time of dispatch from the time of arrival. The difference between fire and ambulance response time was the time fire had to initiate care. Both agencies were simultaneously dispatched to 4752 incidents. Average response time for all incidents was 4.0 +/- 2.6 min for fire and 5.3 +/- 2.0 min for ambulance. Fire had 1.3 +/- 3.2 min on average to initiate care. Fire arrived before ambulance for 69% (3262) of requests and for these calls had 2.8 +/- 1.7 min on average to initiate care. Utilization of densely staged first-response fire apparatus in a midsize city may be appropriate because firefighters frequently arrive before ambulances and may have adequate time to initiate lifesaving interventions.

Can paramedics safely treat and discharge hypoglycemic patients in the field?

To determine whether paramedics can safely treat and discharge insulin-dependent diabetic patients experiencing uncomplicated hypoglycemic events, we conducted a prospective, observational study with a convenience sample of diabetic patients whose hypoglycemia resolved after intravenous administration of dextrose and before they were transported by paramedics. On-line medical control was contacted to obtain approval and informed consent for participation from interested patients who met all eligibility criteria for the study. Participating patients were given instructions upon discharge from the study and were contacted by telephone 24 hours later to ascertain their medical outcomes and their opinions of the study protocol. We enrolled a total of 36 patients with 38 incidents of hypoglycemia. Of these, 91% reported no complications after discharge. Two patients developed recurrent hypoglycemia but treated themselves and did not require further emergency care. One further patient was found unresponsive on the morning following discharge and was subsequently admitted to a long-term care facility with hypoglycemic encephalopathy. Of the study participants, 85% were very satisfied with not being transported to an emergency department (ED) and 91% were very satisfied with the care they had received. All (100%) of the patients surveyed favored a permanent protocol allowing discharge of hypoglycemic patients without admission to an ED. We conclude that paramedics successfully treated, without complication, most of the patients with uncomplicated hypoglycemic events who were examined in our study. These patients generally preferred discharge without transportation to an ED.

Is total out-of-hospital time a significant predictor of trauma patient mortality?

OBJECTIVE: To determine if there is an association between total out-of-hospital time and trauma patient mortality. METHODS: A retrospective review was performed of a convenience sample of consecutive medical records for all admitted patients transported by helicopter or ambulance from the scene of injury to the regional trauma center. Descriptive and univariate analyses were conducted to determine which variables were associated with patient mortality and total out-of-hospital time. Multiple predictors logistic regression was used to determine if total out-of-hospital time was associated with trauma patient outcome, while controlling for the variables associated with trauma patient mortality. RESULTS: Of the 2,925 patients who were transported from the scene, 1,877 met the inclusion criteria. Six percent (116) did not survive. The multiple predictors model included CUPS (critical, unstable, potentially unstable, stable) status, patient age, Injury Severity Score, Revised Trauma Score, and total out-of-hospital time as predictors of mortality. Total out-of-hospital time (odds ratio 0.987; p = 0.092) was the only variable not found to be a significant predictor of mortality. CONCLUSIONS: Provider-assigned CUPS status, patient age, Injury Severity Score, and Revised Trauma Score all were significant predictors of trauma patient mortality. Total out-of-hospital time was not associated with mortality.

Out-of-hospital do-not-resuscitate orders by primary care physicians.

The objective of this study was to determine the knowledge, utilization, and experience of primary care physicians (PCPs) with nonhospital do-not-resuscitate (NH-DNR) orders. An anonymous survey was sent to all PCPs in a single northeastern county. Up to two surveys were mailed to each PCP. Descriptive statistics were used to report provider responses. The main variable of interest was issuance of NH-DNR orders. Surveys were mailed to 820 PCPs; 348 (42%) were returned. Respondents had practiced an average 17 +/- 11 years, and cared for an average of 720 patients per month, 7 of whom were terminally ill. Seventy percent issued NH-DNR orders. Twenty-five percent reported resuscitation had been attempted for at least one patient with a NH-DNR order; 64% reported this had happened more than once. Of respondents who had a NH-DNR order ignored, 14% had instructed family members to call police, fire, or EMS following death of the patient. Of the PCPs who did not issue NH-DNR orders, 71% reported not caring for any appropriate patients, yet 41% reported caring for at least 1 terminally ill patient per month. Seventy-nine percent disagreed that intubation and mechanical ventilation were appropriate treatment for DNR patients in severe respiratory distress, and 71% disagreed that cardioversion was appropriate treatment for an unconscious DNR patient with unstable ventricular tachycardia. In conclusion, a majority of respondents issued NH-DNR orders and one quarter reported these orders had not been followed. A majority felt intubation, mechanical ventilation, and cardioversion should not be performed for noncardiac arrest DNR patients with an indication, but not in cardiac arrest.

Assessment of emergency department health care professionals' behaviors regarding HIV testing and referral for patients with STDs.

The objective of this study was to evaluate human immunodeficiency virus (HIV) counseling, testing, and referral practices of emergency department health care professionals (i.e., medical doctors [MD], physician assistants [PA], nurse practitioners [NP], and registered nurses [RN]) for patients presenting with other sexually transmitted diseases (STD). All health care professionals from 10 emergency departments in a northeastern county were asked to complete an anonymous survey. The surveys were returned by 154 (41%) health care professionals (RN = 99, NP = 5, PA = 7, MD = 39, other = 4). The average years in practice were 11. Only 7% of respondents were certified to provide state mandated HIV pretest counseling (certification not required for MD). Respondents reported caring for an average of 13 patients per week with suspected STD. Fifty-five percent of respondents reported that they always or usually warn STD patients of their HIV risk, yet only 10% always or usually encouraged these patients to consent to HIV testing in their emergency department (RN = 7%, NP = 25%, PA = 0%, MD = 16%). Reasons for not offering HIV testing in their emergency department were follow-up concerns (51%), not certified to provide pretest/posttest counseling (45%), and too time consuming (19%). Twenty-seven percent of respondents indicated HIV testing was not available in their emergency department despite all hospital laboratories reporting HIV testing capability. Ninety-three percent of respondents were aware that confidential testing sites were available, but only 35% always or usually referred patients not tested in the emergency department elsewhere for testing. Emergency department health care professionals frequently fail to provide HIV counseling, testing, and/or referral for patients with suspected STD.

Emergency physician practices and requirements regarding the medical screening examination of psychiatric patients.

OBJECTIVE: To describe the testing requirements and practices of emergency physicians (EPs) when conducting a medical screening examination of psychiatric patients. METHODS: An anonymous survey was developed and mailed to 500 EPs randomly selected through American College of Emergency Physicians membership rolls. RESULTS: Two hundred ninety surveys were returned (58%). Eighty-five percent of the respondents were male, 70% practiced in a community setting and 28% in an academic setting, 58% were emergency medicine (EM) residency-trained, and 88% were EM board-certified or board-eligible. Ninety-eight percent stated they were actively involved with the psychiatric medical screening exam (PMSE). Routine testing was required by 35% of the respondents, with 16% being required by ED protocol, and 84% by the psychiatrist/psychiatric institute. Of those with required testing, tests required were: complete blood cell count (56%), electrolytes (56%), serum alcohol (85%), serum toxicology screen (31%), urine toxicology screen (86%), electrocardiogram (18%), liver function test (16%), blood urea nitrogen (45%), and creatinine (40%). Many clinicians believed that certain tests were unnecessary as part of a PMSE. There was no statistical difference between the opinions of the physicians required to test and those not required to test in terms of which tests they thought were a necessary part of a PMSE regardless of the patient's clinical presentation. The EM-trained physicians were also found to be significantly less likely to think certain tests were necessary for the PMSE when compared with the non-EM-trained physicians. CONCLUSIONS: Routine testing was required as part of the medical screening examination of psychiatric patients for only one-third of the respondents. Few respondents believed that any of these tests were necessary. Emergency medicine-trained physicians were less likely to feel that routine testing was necessary.

An evaluation of paramedics' ability to screen older adults during emergency responses.

OBJECTIVES: This study evaluated the feasibility of using the emergency medical services (EMS) system as a public health provider by having paramedics screen older adults (age >or= 65 years) for influenza immunization status during emergency responses. It also determined the proportion of older-adult EMS patients who lacked an influenza vaccination. METHODS: A retrospective descriptive study was performed, with medical-record review for patients treated between January 2003 and April 2003. Patients were included if they were age 65 years and older, requested assistance via a 9-1-1 call, and were treated by one of 13 paramedics using a directed medical record. The authors calculated the proportion of patients successfully screened and the proportion who reported being nonimmunized. They also compared the patients screened and not screened by the EMS providers and patients who reported being immunized and reported being nonimmunized. RESULTS: Two hundred eighty-eight patients were eligible; the median age was 80 years, 53% were women, 73% were white, and 59% required advanced life support care. Paramedics successfully screened 177 patients (61%; 95% CI, 56-67%). Sixty-five patients (37%; 95% CI, 30-44%) reported being nonimmunized. Failure to screen was associated with a Glasgow Coma Scale score of 13 or less. Lack of immunization was associated with younger age and female gender. CONCLUSION: Paramedics can screen a majority of older adults for influenza immunization status during emergency responses. Older adult users of EMS reported lacking influenza vaccination at levels similar to national estimates. An EMS-based, paramedic-implemented screening program has the potential to identify older adults at risk for preventable illnesses and to augment traditional screening programs, but additional measures are needed to enhance screening rates.

Automated external defibrillator (AED) utilization rates and reasons fire and police first responders did not apply AEDs.

OBJECTIVES: To determine the rate at which fire and police first responders (FRs) apply automated external defibrillators (AEDs) and to ascertain reasons for not applying them. METHODS: Twenty-one emergency medical services (EMS) systems whose FRs had been supplied with AEDs by a philanthropic foundation provided data for all out-of-hospital cardiac arrest (OHCA) patients. Data including the incidence of AED application and explanations for not applying AEDs were analyzed using descriptive statistics. RESULTS: A total of 2,456 OHCAs were reported. AED application information was available for 2,439 patients and revealed that FRs had not applied AEDs to 1,025 patients (42%). Fire FRs were more likely than police FRs to have applied AEDs (relative risk 1.87, 95% confidence interval 1.65-2.12). Reasons for not applying AEDs were listed for 664 (65%) of the OHCA patients to whom AEDs had not been applied. The predominant reason the FRs did not apply an AED was that the transporting ambulance defibrillator had already been applied (74%). However, when response times for FRs and the transporting ambulances were compared for these OHCA patients, it was found that the transporting ambulances arrived after the FRs 23% the time, simultaneously with the FRs 45% of the time, and before the FRs only 32% of the time. CONCLUSION: Fire and police FRs did not apply AEDs to a significant number of OHCA patients. Use of the transport ambulance defibrillator was the primary reason given for not applying the FR AED. Given low AED application rates by FRs, future studies are needed to determine the characteristics of communities in which equipping FRs with AEDs is the most beneficial deployment strategy, and how to increase AED application by FRs in communities with FR AED programs.
