Impact of the Privacy Rule on the Study of Out-of-Hospital Pediatric Cardiac Arrest

Introduction. The Privacy Rule, a follow-up to the Health Insurance Portability andAccountability Act, limits distribution of protected health information. Compliance with the Privacy Rule is particularly challenging for prehospital research, because investigators often seek data from multiple emergency medical services (EMS) andreceiving hospitals. Objective. To describe the impact of the Privacy Rule on prehospital research andto present strategies to optimize data collection in compliance with the Privacy Rule. Methods. The CanAm Pediatric Cardiopulmonary Arrest Study Group has previously conducted a multicentered observational study involving children with out-of-hospital cardiac arrest. In the current study, we used a survey to assess site-specific methods of compliance with the Privacy Rule andthe extent to which such strategies were successful. Results. The previously conducted observational study included collection of data from a total of 66 EMS agencies (range of 1–37 per site). Data collection from EMS providers was complicated by the lack of a systematic approval mechanism for the research use of EMS records andby incomplete resuscitation records. Agencies approached for approval to release EMS data for study purposes included Department of Health Institutional Review Boards, Fire Commissioners, andCommissioners of Health. The observational study included collection of data from a total of 164 receiving hospitals (range of 1–63 per site). Data collection from receiving hospitals was complicated by the varying requirements of receiving hospitals for the release of patient survival data. Conclusions. Obtaining complete EMS andhospital data is challenging but is vital to the conduct of prehospital research. Obtaining approval from city or state level IRBs or Privacy Boards may help optimize data collection. Uniformity of methods to adhere to regulatory requirements would ease the conduct of prehospital research.     

Accuracy of EMS-Recorded Patient Demographic Data

Objective. Emergency medical services (EMS) research is frequently dependent on data recorded by prehospital personnel. Linking EMS information with hospital outcome depends on essential identifying data. We sought to determine the accuracy of these data in patients who activated EMS for chest pain andto describe the types of errors committed. Methods. We performed a retrospective, consecutive case series study of all prehospital records for patients transported by the City of Pittsburgh Bureau of EMS (annual call volume, 60,000) for chest pain to three area hospitals during a three-month interval. Demographic data, including name, date of birth (DOB), andSocial Security number (SSN), for each patient were extracted from the EMS record. These were compared to the definitive information in the hospital records. Results. 360 prehospital records were examined, with 341 matches to hospital records. The correct patient name was recorded in 301 records (83.6%), the correct DOB was recorded 284 times (78.9%), andthe correct SSN was recorded 120 times (33.3%). The overall error rate of demographic data recorded on EMS records was 73.9% (266/360). If SSN is not included as a demographic variable, then the overall error rate was 25.3% (91/360). Conclusion. The use of EMS-generated demographic data demonstrates moderate agreement andlinkage with hospital records. Name andDOB are more reliable data elements for matching than SSN. Future research should examine the impact of electronic medical records andEMS identification numbers on data reliability.     

电子病历数据库在临床研究中的应用及偏倚控制

电子病历数据库(electronic health records, EHRs)的出现为大样本临床队列研究提供了低成本、高效率的愿景和机遇,但利用EHRs开展临床研究仍然存在误区和挑战。本文回归流行病学的本质,通过实例探讨EHRs的特征,EHRs中可获得的信息与临床研究中暴露变量、结局变量及协变量之间的对应关系,如何利用EHRs进行患病率及发病率估计、开展疗效和政策评价以及在临床研究中对选择偏倚、混杂偏倚尤其是未测量混杂偏倚的控制等,旨在促进EHRs与临床研究的整合,提高临床研究的效率及质量。     

Hospital Variability of Out-of-Hospital Cardiac Arrest Survival

Background. Previous literature has identified patient andemergency medical services (EMS) system factors that are associated with survival of out-of-hospital cardiac arrest patients. Objective. To determine variability in rates of survival to discharge of resuscitated adult out-of-hospital cardiac arrest patients andto identify hospital-related factors associated with survival. Methods. This was a retrospective, observational study of all adult (21 years or older) out-of-hospital Utstein criteria cardiac-etiology arrests treated by Milwaukee County EMS during the period 1995–2005 andsurviving to hospital intensive care unit admission. The primary outcome measure was survival to hospital discharge. Logistic regression analysis was used to compare the odds of survival between hospitals, patient factors, andhospital factors. Results. 1,702 patients at eight receiving hospitals were included in the study analyses. Hospital survival rates ranged from 29% to 42%. Patient andcase factors associated with increased survival included younger age, male gender, nonwhite race, witnessed arrest in a public location, bystander cardiopulmonary resuscitation (CPR), a modest number of defibrillations, andinitial cardiac rhythm of ventricular tachycardia. The only hospital characteristic correlated with survival was the number of beds per nurse. Patients admitted to a hospital with a ratio of beds to nurse less than 1.0 were over 1.5 times more likely to survive. Conclusions. Survival to discharge of resuscitated adult out-of-hospital cardiac arrest patients may vary by receiving hospital. A hospital's ratio of beds to nurse andseveral patient/case f actors are correlated with survival. Further research is warranted to investigate how this may affect resuscitation care, EMS transport policy, andresearch design.     

Electronic health records: a primer for practicing physicians

Electronic health records (EHRs) offer a number of advantages over the old paper record. They have the potential to improve the quality of patient care, reduce the cost of health care, and expedite the transfer of information. Yet fewer than 20% of hospitals and physician practices now use them. We discuss the advantages of EHRs, reasons for adopting this system, current barriers to the adoption of EHRs, and issues to consider when choosing a system.     

Motivations and barriers to implementing electronic health records and ED information systems in Japan

Background

Although electronic health record systems (EHRs) and emergency department information systems (EDISs) enable safe, efficient, and high-quality care, these systems have not yet been studied well. Here, we assessed (1) the prevalence of EHRs and EDISs, (2) changes in efficiency in emergency medical practices after introducing EHR and EDIS, and (3) barriers to and expectations from the EHR-EDIS transition in EDs of medical facilities with EHRs in Japan.

Materials and methods

A survey regarding EHR (basic or comprehensive) and EDIS implementation was mailed to 466 hospitals. We examined the efficiency after EHR implementation and perceived barriers and expectations regarding the use of EDIS with existing EHRs. The survey was completed anonymously.

Results

Totally, 215 hospitals completed the survey (response rate, 46.1%), of which, 76.3% had basic EHRs, 4.2% had comprehensive EHRs, and 1.9% had EDISs. After introducing EHRs and EDISs, a reduction in the time required to access previous patient information and share patient information was noted, but no change was observed in the time required to produce medical records and the overall time for each medical care. For hospitals with EHRs, the most commonly cited barriers to EDIS implementation were inadequate funding for adoption and maintenance and potential adverse effects on workflow. The most desired function in the EHR-EDIS transition was establishing appropriate clinical guidelines for residents within their system.

Conclusion

To attract EDs to EDIS from EHR, systems focusing on decreasing the time required to produce medical records and establishing appropriate clinical guidelines for residents are required.     

A Link to Improve Stroke Patient Care: A Successful Linkage Between a Statewide Emergency Medical Services Data System and a Stroke Registry

Objectives: Regionalization of stroke care, including diversion to stroke centers, requires that emergency medical services (EMS) systems accurately identify acute stroke patients. A barrier to evaluating and improving EMS stroke patient identification is the inability to link EMS data with hospital data for individual patients. We sought to create and validate a linkage of the North Carolina EMS Data System (NC‐EMS‐DS) with data contained in the North Carolina Stroke Care Collaborative (NCSCC) Registry. Methods: All NCSCC Registry patients arriving to one of three hospitals by EMS in a 6‐month period were matched against NC‐EMS‐DS. Records were deterministically matched on receiving hospital, hospital arrival date/time, age, and sex. We performed linkage validation by providing each site investigator with a stroke patient list derived from North Carolina Stroke Care Collaborative Registry (NC‐EMS‐DS), matched by individual patient to deidentified data in the NCSCCR. Each site investigator determined the set of true matches by comparing the matched list to a NCSCCR patient identifier key maintained at each site. Incorrect matches were reviewed by the research team to identify methods for future improvement in the matching logic. Results: For the three validation hospitals, 753 NCSCC Registry patients arrived by EMS. For these patients, 473 (63%) matches to local EMS records were identified, and 421 (89%) of the matches were verified using full patient identifiers. Most match verification failures were due to incorrect date/time stamp and inability to find a corresponding EMS record. Conclusions: Linking EMS records electronically to a stroke registry is feasible and leads to a large number of valid matches. This small validation is limited by EMS data quality. Matching may improve with better EMS documentation and standardized facility documentation. ACADEMIC EMERGENCY MEDICINE 2010; 17:1398–1404 © 2010 by the Society for Academic Emergency Medicine     

Out-of-hospital and Emergency Department Management of Epidemic Scombroid Poisoning

OBJECTIVE: To report two epidemic outbreaks of scombroid food poisoning and their emergency medical services (EMS) response and emergency department (ED) treatment, analyzing the impact of early physician involvement and on-line medical control. METHODS: Retrospective case series of two multiple-casualty incidents (MCIs) involving scombroid food poisoning. RESULTS: A total 57 patients were treated from two separate incidents, with 30 patients transported to area hospitals. One patient required treatment with a cardiac medication in the field and another patient eventually required hospital admission. On-scene medical control (incident 1) and early identification of the index case (incident 2) were instrumental to out-of-hospital care interventions and conservation of resources. Patient triage, field treatment, and hospital transport were expedited, with some patients treated and released from the scene. CONCLUSIONS: Immediate diagnosis of a food-borne illness in the out-of-hospital setting allows rapid treatment at the scene and allows for the efficient transport of multiple patients to a single receiving facility. EMS medical directors should be able to immediately respond to such incidents to make presumptive diagnoses and accurately direct patient care. When this is not possible, early identification of the index case facilitates early diagnosis and treatment.     

Out-of-hospital deliveries: a five-year experience

INTRODUCTION: Prehospital providers regularly encounter patients with obstetrical emergencies. This study determined the frequency and outcome of out-of-hospital deliveries in an urban, all advanced life support (ALS) emergency medical services (EMS) system. METHODS: Retrospective review of all out-of-hospital records that involved women delivering babies in the care of prehospital providers from 1984-1988. The EMS system answered an average of 62,000 calls during the study period. The records of these patients were identified through a computer database. RESULTS: A total of 81 out-of-hospital deliveries (1.4/month) occurred during the study years. The average age of the mothers was 24 years, and the average gestation period was 30 weeks. The women had an average of three previous pregnancies and two previous deliveries, and 10 were primagravida. Seventy-two (89%) of the deliveries occurred in the home. The paramedics encountered a variety of obstetrical and neonatal complications in 34% of the patient encounters. Nine neonates were delivered prior to the arrival of the paramedic team. Twenty-four neonates had Apgar scores calculated, and the one- and five-minute scores averaged eight and nine respectively. Five of the mothers had no prenatal care. Maternal complications included four patients noted to be hypertensive with the delivery, nine patients had some degree of vaginal bleeding, and in 33 patients, the prehospital providers did not deliver the placenta in the field. An EMS physician was in attendance for only two of the out-of-hospital deliveries. DISCUSSION: In this urban EMS system, out-of-hospital deliveries, especially pre-term deliveries, are a common event. There appears to be a significant number of neonatal complications that confront paramedics. Generally, the paramedics were deficient in their documentation of the neonatal assessment. Continuing educational programs for paramedics should include reviewing normal and complicated vaginal deliveries as well as ALS measures for neonates. Protocols for obstetrical emergencies need to be developed and subjected to quality improvement measures. CONCLUSIONS: Paramedics, especially those in urban settings, are likely to encounter obstetrical and neonatal emergencies and a significant number of associated complications. Emergency medical services systems and medical directors should have in place continuing educational programs, patient-care protocols, and continuous quality improvement measures to evaluate the care rendered to patients having out-of-hospital deliveries.     

Out-of-hospital cardiopulmonary resuscitation: a population-based Norwegian study of incidence and survival.

The Trondheim region's (315 km2, population 154,000) emergency medical service (EMS) provides advanced cardiac life support (ACLS) with combined paramedic and physician response. This EMS system is commonly employed in Norway, yet no population based study of outcome in cardiac arrest has been published to date. This retrospective study reports incidence and outcome from every attempted out-of-hospital cardiopulmonary resuscitation (CPR) during 1990 through 1994 according to the Utstein template. Information on the patient's pre-morbid conditions and final outcome was obtained from hospital records. The incidence of cardiac arrest and CPR from all causes was 68 per 100,000 per year, with 83% primary cardiac aetiology. The median alarm to patient arrival interval for ambulance and emergency physician was 8 minutes and 11 minutes, respectively. The presenting rhythm was ventricular fibrillation or tachycardia in 51%, asystole in 34%, pulseless electrical activity in 8% and undetermined in 8%. Definite return of spontaneous circulation occurred in 211 patients (40%, 27 per 100,000 per year) and 57 patients (11%, 7.4 per 100,000 per year) survived to discharge. Most patients made a favourable cerebral outcome, although nine were severely disabled. This is the first population-based Norwegian study of outcome from out-of-hospital cardiac arrest in this combined paramedic/physician staffed EMS. Incidence, survival and neurological outcome are comparable with results obtained in other EMS systems.     

Emergency Medical Service Providers' Attitudes andExperiences Regarding Enrolling Patients in Clinical Research Trials

Objective: The purpose of this study was to evaluate Emergency Medical Services (EMS) providers' attitudes andexperiences about enrolling patients in clinical research trials utilizing the federal rules for exception from informed consent. We hypothesized that Emergency Medical Technicians (EMTs) would have varied attitudes about research using an exception from informed consent which could have an impact on the research. Methods andsetting: Since January 2007, the EMS system has been participating in a randomized, multi-center interventional trial in which out-of-hospital providers enroll critically injured trauma patients using exception from informed consent.A voluntary, anonymous, written survey was administered to EMS providers during an in-service. The survey included demographics andLikert-type questions about their experiences with andattitudes towards research in general, andresearch using an exception from informed consent for an out-of-hospital clinical trial. Results: The response rate was 79.3% (844/1067). Most respondents, 93.3%, agreed that “research in EMS care is important.” However, 38.5% also agreed that individual EMTs/paramedics should maintain the personal right of refusal to enroll patients in EMS trials. Fifty-four percent of respondents agreed with the statement that “the right of research subjects to make their own choices is more important than the interests of the general community.” In response to statements about the current study, 11.3% agreed that “the study is unethical because the patient cannot consent” and69.2% responded that they would personally be willing to be enrolled in the study before they were able to give consent if they were seriously injured. Those who had not enrolled a patient into the study (681 respondents) were asked their reasons: 76.8% had not encountered an eligible patient or did not work for an agency that carried the fluid; 4.3% did not have time; 4.1% forgot and1.1% stated that they were opposed to enrolling patients in studies without their consent. Conclusion: The majority of EMS personnel in one community support EMS research andthis specific out-of-hospital clinical trial being conducted under an exception from informed consent. Potential barriers to enrollment were identified. Further study in other systems is warranted to better understand EMS provider perspectives about exception from informed consent research.     

Electronic Health Records in Danish Home Care and Nursing Homes: Inadequate Documentation of Care,Medication, and Consent

Background  Electronic health records (EHRs) are used in long-term care to document the patients'' condition, medication, and care, thereby supporting communication among caregivers and counteracting adverse drug events. However, the use of EHRs in long-term care has lagged behind EHR use in hospitals. In addition, most EHR research focuses on hospitals. Objective  This study gives a countrywide status of the documentation-related risks to patient safety in Danish home care and nursing homes, which are the two main providers of long-term care. Such a status provides a basis for national improvement efforts and international comparisons. Method  The study is based on the reports from 893 inspections of home care and nursing homes by the Danish Patient Safety Authority (Styrelsen for Patientsikkerhed [STPS]). Results  As much as 69% of the inspected institutions document inadequately to an extent that has led to demands (i.e., issues the institution is legally obliged to rectify) or requests (i.e., issues the institution is merely asked to rectify) from STPS. Documentation issues about the patients'' condition and care are present in nearly all institutions that receive demands (97%) and in the majority of those that receive requests (68%). Documentation issues about medication and consent to care are also common, but less so. The predominant risk to patient safety is incomplete documentation. It covers 72% of the documentation issues identified in the institutions that received demands; the remaining risks concern inconsistent (11%), nonexistent (7%), inaccessible (5%), and noncompliant (5%) documentation. The documentation inadequacies are similar for home care and nursing homes. Conclusion  Inadequate EHR documentation is a widespread problem in Danish long-term care. While previous research mainly focuses on how EHR documentation affects patient medication, this study finds that documentation issues about the patients'' condition and care are more prevalent and that issues about their consent are also common.     

Satisfaction of health‐care providers with electronic health records and perceived barriers to its implementation in the United Arab Emirates

The integration of electronic health records (EHRs) has shown promise in improving health‐care quality. In the United Arab Emirates, EHRs have been recently adopted to improve the quality and safety of patient care. A cross‐sectional survey of 680 health‐care providers (HCPs) was conducted to assess the satisfaction of HCPs in the United Arab Emirates with EHRs' impact on access/viewing, documentation and medication administration and to explore the barriers encountered in their use. Data were collected over 6 months from April to September 2014. High overall satisfaction with EHRs was reported by HCPs, suggesting their acceptance. Physicians reported the greatest overall satisfaction with EHRs, although nurses showed significantly higher satisfaction with the impact on medication administration compared with other HCPs. The most significant barriers reported by nurses were lack of belief in the value of EHRs for patients and lack of adequate computer skills. Given the large investment in technology, additional research is necessary to promote the full utilization of EHRs. Nurses need to be aware of the value of EHRs for patient care and be involved in all stages of EHR implementations to maximize its meaningful use for better clinical outcomes.     

Delay to initiation of out-of-hospital cardiac arrest EMS treatments

BackgroundTime to initial treatment is important in any response to out-of-hospital cardiac arrest (OHCA). The purpose of this paper was to quantify the time delay for providing initial EMS treatments supplemented by comparison with those of other EMS systems conducting clinical trials.MethodsData were collected between 1/1/16–2/15/19. Dispatched, EMS-worked, adult OHCA cases occurring before EMS arrival were included and compared with published treatment time data.Response time and time-to-treatment intervals were profiled in both groups. Time intervals were calculated by subtracting the following timepoints from 9-1-1 call receipt: ambulance in route; at curb; patient contact; first defibrillation; first epinephrine; and first antiarrhythmic.Results342 subjects met study inclusion/exclusion. Mean time intervals (min [95%CI]) from 9-1-1 call receipt to the following EMS endpoints were: dispatch 0.1 [0.05–0.2]; at curb 5.0 [4.5, 5.5]; at patient 6.7 [6.1, 7.2];, first defibrillation initially shockable 11.7 [10.1, 13.3]; first epinephrine (initially shockable 15.0 [12.8, 17.2], initially non-shockable 14.8 [13.5, 15.9]), first antiarrhythmic 25.1 [22.0, 28.2]. These findings were similar to data in 5 published clinical trials involving 12,954 subjects.ConclusionsDelay to EMS treatments are common and may affect clinical outcomes. Neither Utstein out-of-hospital guidelines [1] nor U.S. Cardiac Arrest Registry to Enhance Survival (CARES) databases require capture of these elements. EMS is often not providing treatments quickly enough to optimize clinical outcomes. Further regulatory change/research are needed to determine whether OHCA outcome can be improved by novel changes such as enhancing bystander effectiveness through drone-delivered drugs/devices & real-time dispatcher direction on their use.     

Probabilistic Linkage of Prehospital and Outcomes Data in Out-of-hospital Cardiac Arrest

Abstract

Objective. Lack of longitudinal patient outcome data is an important barrier in emergency medical services (EMS) research. We aimed to demonstrate the feasibility of linking prehospital data from the California EMS Information Systems (CEMSIS) database to outcomes data from the California Office of Statewide Health Planning and Development (OSHPD) database for patients with out-of-hospital cardiac arrest (OHCA). Methods. We included patients age 18 years or older who sustained nontraumatic OHCA and were included in the 2010–2011 CEMSIS databases. The CEMSIS database is a unified EMS data collection system for California. The OSHPD database is a comprehensive data collection system for patient-level inpatient and emergency department encounters in California. OHCA patients were identified in the CEMSIS database using cardiac rhythm, procedures, medications, and provider impression. Probabilistic linkage blocks were created using in-hospital death or one of the following primary or secondary diagnoses (ICD-9-CM) in the OSHPD databases: cardiac arrest (427.5), sudden death (798), ventricular tachycardia (427.1), ventricular fibrillation (427.4), and acute myocardial infarction (410.xx). Blocking variables included incident date, gender, date of birth, age, and/or destination facility. Due to the volume of cases, match thresholds were established based on clerical record review for each block individually. Match variables included incident date, destination facility, date of birth, sex, race, and ethnicity. Results. Of the 14,603 cases of OHCA we identified in CEMSIS, 91 (0.6%) duplicate records were excluded. Overall, 46% of the data used in the linkage algorithm were missing in CEMSIS. We linked 4,961/14,512 (34.2%) records. Linkage rates varied significantly by local EMS agency, ranging from 1.4 to 61.1% (OR for linkage 0.009–0.76; p < 0.0001). After excluding the local EMS agency with the outlying low linkage rate, we linked 4,934/12,596 (39.2%) records. Conclusion. Probabilistic linkage of CEMSIS prehospital data with OSHPD outcomes data was severely limited by the completeness of the EMS data. States and EMS agencies should aim to overcome data limitations so that more effective linkages are possible.     

Electronic Medical Records and Electronic Health Records: Overview for Nurse Practitioners

Electronic medical records (EMRs) and electronic health records (EHRs) have become essential systems by which nurse practitioners (NPs) communicate vital patient information to other members of the health care team as well as to patients. In this article we examine the important distinctions between EMRs and EHRs; review the genesis of these types of records; summarize applicable provisions of the Health Insurance Portability and Accountability Act from a recent legal case centered around NP utilization of EMRs and EHRs; address open patient access to medical information; and examine threats to security. Suggestions are offered on ways in which NPs can safeguard confidential patient information.
