Evaluation of certifier practices regarding alcohol-related deaths: Fulton County Medical Examiner's Center, Atlanta, Georgia, 2004

CONTEXT: Alcohol can contribute to various manners of death by acute intoxication that places a person at risk for fatal injury, acute fatal alcohol poisoning, or the various fatal complications of chronic abuse with or without superimposed acute intoxication. The reporting of alcohol use on the death certificate may vary with office policy or procedure, certifier judgment, and the timing of information received during investigation. OBJECTIVE: To determine the number of deaths including mention of alcohol use in the investigative case file, the number of death certificates on which alcohol use is reported, the number of discrepancies between the 2, and the possible reasons for observed discrepancies. DESIGN, SETTING, AND PARTICIPANTS: Retrospective case review of all deaths where alcohol use was mentioned in the investigative case file and/or on the death certificate for deaths investigated by the Fulton County Medical Examiner in Atlanta, Georgia, during a 1-year period between January 1, 2004, and December 31, 2004. MAIN OUTCOME MEASURES: Percentage of deaths with alcohol use reported on the death certificate, tabulation of where and how alcohol use is reported on the death certificate, and tabulation of the differences between the investigative case file and death certificate regarding alcohol's possible role in causing death. RESULTS: Among the 1324 deaths certified by the office, 105 (8%) had alcohol use reported on the death certificate. The majority (67%) of these cases were natural deaths. Sixty-nine (5%) deaths had mention of alcohol use in the investigative case notes but did not include it on the death certificate. Twenty-five (2%) deaths had mention of alcohol on the death certificate but did not have mention of it in the investigative case file based on our search criteria. However, subsequent review of additional case follow-up information disclosed a history of alcohol use or acute intoxication in each case. CONCLUSIONS: The data show that more natural deaths are considered to be directly caused by alcohol than other manners of death. For the unnatural manners of death (excluding acute alcohol poisoning), alcohol use is often viewed by medical examiners as an incidental, associated finding or risk factor surrounding the circumstances of death rather than being an actual cause of death. In such cases, alcohol use is often omitted from the death certificate. For deaths directly caused by alcohol, the proportion of cases involving possible underreporting or overreporting of alcohol involvement was relatively small and usually involved the omission of chronic alcohol use from the death certificate. Researchers need to be aware of potential limitations of death certificate data for studying alcohol-related deaths.     

Errors on death certificates requiring amendments: the Broward County experience

The medical examiner's office in Broward County is responsible for determining the cause and manner of death in cases falling under its jurisdiction and issuing death certificates on these decedents. Amendments are occasionally required to correct misinformation on death certificates or within the autopsy reports. The purpose of this study was to investigate the major causes for the amendments and to develop strategies to avoid future errors. We found 128 cases from 2006 to 2007 that required amendments; 103 contained sufficient data in the file for further analysis. Over this time period, 3790 death certificates were issued over that same period, resulting in a 3.37% amendment rate. In this study, the cohort included both males and females with a ratio of 2:1. Their ages ranged from newborn to 103 years, with a mean age of 49 years. Of the 103 amended cases, amendments were made to the cause (n = 30) and often the manner (n = 21) of death listed on the death certificate; the remaining changes were limited to the autopsy report. The most common reasons for amendments included reception of delayed laboratory findings (35%), acquisition of additional medical history (22.5%), and typographic errors (15.5%). Typographic errors mainly occurred because of inaccuracies in the names originally provided to our office, the use of aliases by decedents, incorrect personal/demographic history, or various misspellings by funeral homes or medical examiner staff. The most significant reclassifications involved changing certified natural deaths to accidental overdoses and vice versa, based on toxicological analysis. Because of delays in specimen turnaround, these amendments often were made months after the original death certificate was issued. STAT urine drug screening has been helpful in reducing the number of amendments made, but certain drugs of significance are missed by rapid screens. Given that our office performed complete toxicological analysis on all cases over this period, it seems likely that we detected several overdoses that would have been missed if natural deaths were not routinely screened for potential toxins.     

Investigation of elderly deaths in nursing homes by the medical examiner over a year

Despite death being one of the most common reasons for discharge from a nursing home, fewer than 1% of nursing home resident deaths are autopsied. To evaluate our role as medical examiner in nursing home deaths, we conducted a retrospective review of all decedents in Jefferson County, Alabama, for the year 2001. Death certificate data indicate that 995 deaths occurred in nursing homes in Jefferson County in 2001. Of those 995 deaths, 119 (12%) were reported to the Jefferson County Coroner/Medical Examiner Office. Jurisdiction was accepted in 5 cases in which the circumstances already made clear that the death was a nonnatural event. In the remaining 96% of nursing home deaths reported to the medical examiner, the statements of the reporting person were taken to be true concerning the expected nature of the death. An independent scene evaluation was provided by a police officer or paramedic in 82% of the cases reported to the medical examiner's office. Elderly individuals, as a group, are expected to die, but the death of a particular elder may or may not be expected. In our jurisdiction, only 12% of all nursing home deaths are reported to our office, and only 4% of reported deaths are actively investigated. Actively investigating each nursing home death would overwhelm the resources currently available to our office. We advocate the study and development of criteria to aid in determining whether the death of an individual elder is sudden and unexpected.     

Identification of the unidentified deceased: turnaround times, methods, and demographics in Fulton County, Georgia

CONTEXT: Multiple methods may be employed in an attempt to identify deceased individuals who are unidentified when reported to the medical examiner or coroner. The success and turnaround times of various methods differ. OBJECTIVE: To determine the number of deaths initially involving unidentified individuals, their demographics, the methods used and turnaround times for cases in which identification was successful and the portion of cases that remain unidentified for significant periods of time. DESIGN, SETTING, AND PARTICIPANTS: Retrospective case review of all decedents who were initially unidentified when death was reported to the Fulton County Medical Examiner in Atlanta, Georgia, during a 1-year period between May 2003 and May 2004. MAIN OUTCOME MEASURES: Rate per 1000 deaths which involved an unidentified decedent, tabulation of methods used to make identifications, and rate of cases remaining unidentified. RESULTS: Of 2279 deaths reported to the office, 100 were originally unidentified, resulting in a rate of 44 unidentified decedents per 1000 deaths reported. Those who remained unidentified involved 6 cases, resulting in a "cold case" rate of 2.6 per 1000 deaths. Seventy-eight percent were identified within 2 days, and the most common successful methods were visual identification (52%) and fingerprints (31%). Dental (10%), x-ray (4%), and other methods (6%) were least commonly used. Of the 94 persons identified, all identifications occurred within 29 days. DNA procedures were not needed in most cases, and in the few cases where such tests were needed, results were either unavailable or failed to show a match with known samples. CONCLUSIONS: The majority of unidentified deceased individuals were identified within 2 days, with visual verification or fingerprints accounting for about 83% of methods successfully employed. The medical examiner noted a rate of 44 unidentified deceased persons per 1000 death reports, with an ultimate "cold case" (long-term unidentified) rate of about 2.6 cases per 1000 death reports. These data may be useful in developing office policy and procedure regarding the procedural and temporal aspects of investigations centered on achieving identification and making dispositions of unidentified deceased bodies.     

Detection of medical examiner cases from review of cremation requests

Title 9, Chapter 19, Article 3 of the Arizona Administrative Code requires all bodies that are to be cremated must have the death certificate reviewed by a county medical examiner. In Tucson, AZ, and surrounding Pima County, all cremation requests are submitted to the Forensic Science Center, where the death certificates are reviewed by one of 5 board-certified forensic pathologists. In 2002, there were 5557 cremation requests, and in 2003 there were 5662 cremation requests. Of these requests, 670 (12.1%) and 447 (7.9%) death certificates were flagged for further investigation in 2002 and 2003, respectively. Eventually, 47 cases (0.8% of total, 7.0% of flagged cases) were accepted as medical examiner cases in 2002, and 43 cases (0.8% of total, 9.6% of flagged cases) were accepted as medical examiner cases in 2003. In 2002, the majority of cases were handled as a records review; however, 4 cases were brought in for autopsy and 1 was certified after an external examination only. In 2003, all cases were certified via a records review. The manner of death in all but 3 of these deaths was certified as accident, with complications of remote trauma being the most common proximate cause of death. The 3 most common injuries were complications of fractured pelvis or femur (15 in 2002, 22 in 2003), head injury due to fall (18 in 2002, 8 in 2003), and complications of remote motor vehicle accident (3 in 2002, 6 in 2003). The other 3 deaths included 2 homicides, 1 in each year, and 1 suicide in 2003.     

Medical examiner/coroner records: uses and limitations in occupational injury epidemiologic research

Epidemiologic research often relies on existing data, collected for nonepidemiologic reasons, to support studies. Data are obtained from hospital records, police reports, labor reports, death certificates, or other sources. Medical examiner/coroner records are, however, not often used in epidemiologic studies. The National Institute for Occupational Safety and Health's Division of Safety Research has begun using these records in its research program on work-related trauma. Because medical examiners and coroners have the legal authority and responsibility to investigate all externally caused deaths, these records can be used in surveillance of these deaths. Another use of these records is to validate cases identified by other case ascertainment methods, such as death certificates. Using medical examiner/coroner records also allows rapid identification of work-related deaths without waiting several years for mortality data from state offices of vital statistics. Finally, the records are an invaluable data source since they contain detailed information on the nature of the injury, external cause of death, and results of toxicologic testing, which is often not available from other sources. This paper illustrates some of the ways that medical examiner/coroner records are a valuable source of information for epidemiologic studies and makes recommendations to improve their usefulness.     

Use of "therapeutic complication" as a manner of death

Analyses of deaths due to therapeutic complications (TCs) provide important quality of care information for medical providers. In New York City, 463 deaths were investigated by the Office of Chief Medical Examiner and certified with TC as the manner of death in 2003. The TC manner of death is used for fatalities due to predictable complications of appropriate medical therapy. All death certificates and select autopsy, hospital, and investigation reports were reviewed. Data concerning cause of death, contributing conditions, age, race, and sex were extracted. The types of complications and the causes of death were classified into various types of surgical and nonsurgical categories of complications. These included: postoperative infections, pulmonary emboli, and technical and medication complications. The use of TC as a manner of death has benefits and limitations. Without the TC option, one is forced to certify certain deaths (e.g., penicillin anaphylaxis) either as natural or accident. The TC option allows easy identification and tracking of medical complications for public health purposes and also allows more consistent reporting of natural and medical-accidental deaths. In general, complications that occur during emergency surgeries/procedures for natural disease, tend to be certified with a natural manner. The "but for" test may be used to distinguish natural from TC deaths. There are criteria for distinguishing TC from accidents and homicides. TCs that occur during treatment of a potentially life-threatening injury, are superseded by the manner dictated by the circumstances of the initiating injury. The certification of TC usually does not address errors of omission, clinical judgement/management, or missed diagnoses.     

Nonhuman remains and relics encountered by the medical examiner: Fulton County, Georgia, 2003-2004

BACKGROUND: Medical examiner and coroner offices occasionally respond to "death scenes" which, after investigation, are found to involve nonhuman remains or other relics not requiring further investigation or certification of death. This report describes such cases encountered by the Fulton County medical examiner during 2003 and 2004. METHODS: The electronic database used by the office contains check boxes to indicate whether a reported case involved nonhuman remains or other relics, in which case the name of the "deceased" is listed as "nonhuman remains" by selecting those words from a pull-down menu. Subject cases were identified during the 2-year period by searching the database for any case in which one of the boxes was checked or in which the name of the deceased was listed as nonhuman. RESULTS: Four thousand five hundred fifty-four deaths were investigated during the 2-year period, and 23 cases (0.5%) involved nonhuman remains or relics. Thus, the observed rate was about 5 cases per 1000 death investigations. Nineteen cases involved nonhuman bones. One case involved 2 human fetuses that had been teaching specimens. The other 3 cases involved a nonhuman fetus, a large decomposing dog that had been wrapped and dumped in residential area, and a sheep heart found in a bag which was a medical teaching specimen. CONCLUSIONS: Nonhuman remains and other relics are uncommonly seen in death investigation work and usually involve nonhuman bones, although a small variety of other atypical cases present themselves occasionally. Knowledge of these types of encounters is helpful so that the "unexpected" may become more "expected" and office policy and procedures tailored accordingly to facilitate case management.     

Level of agreement between opinions of medical examiner investigators and forensic pathologist medical examiners regarding the manner of death

To evaluate the level of agreement between medical examiner investigators' opinion of the manner of death and what the manner of death was as certified by forensic pathologist medical examiners (MEs), we reviewed the case records stored in a database of all deaths reported to the office of the medical examiner in Fulton County, Georgia. Of 15,771 deaths reported to the office during a 10-year period, a difference exists in 1908 cases. In 900 natural deaths, the investigators recorded 135 accident, 10 homicide, 10 suicide, and 745 undetermined manners of death. In 755 accidental deaths, the investigators recorded 16 natural, 8 homicide, 13 suicide, and 718 undetermined manners of death. In 107 homicides, the investigators recorded 12 natural, 8 accident, 0 suicide, and 87 undetermined manners of death. In 70 suicides, the investigators recorded 9 natural, 9 accident, 3 homicide, and 49 undetermined manners of death. In 61 deaths classified as undetermined, the investigators recorded 25 natural, 13 accident, 17 homicide, and 6 suicide manners of death. In 15 deaths, the discrepancy exists due to an apparent error in the database information. This study confirms a high concordance between investigator and ME opinion regarding manner of death but also documents the need for case review and autopsies by forensic pathologists to confirm the investigators' opinion of the manner of death, determine the manner of death when the investigator selects undetermined, and on occasion, refute the investigators' opinion regarding the manner of death.     

Amended cause and manner of death certification: a six-year review of the New Mexico experience

Little is known about the amendment of death certificates (DCs) issued by medical examiners and coroners. This retrospective study examined why, how, and with what frequency cause and manner of death were amended on DCs issued by forensic pathologists over a 6-year period at the New Mexico Office of the Medical Investigator. Approximately 1% of DCs had either cause or manner of death amendments, with arteriosclerotic cardiovascular disease and intoxicants the most commonly amended and resulting causes of death, respectively. There was a significant association between manner of death and number of DCs amended (p<0.001). By percent, natural and suicide DCs were the most frequently amended. The way in which manner of death changed was significantly associated with the amount of time elapsed between DCs (p=0.04). Toxicology was the most common reason for DC amendment.     

Report on the 2003 revision of the U.S. Standard Certificate of Death.

The National Center for Health Statistics (NCHS) is responsible for publishing Standard Certificates of Birth and Death for the United States of America. The standard certificates are revised roughly every 10 years. The revision process is designed to ensure that the standard certificates meet, as nearly as possible, the use for which they are intended at all levels: individual, local, state, and federal. The authors report on the most recent revision of the U.S. Standard Certificate of Death, recording the process and the role of the National Association of Medical Examiners in the process. Changes recommended during revision include requesting known aliases of a decedent and rearrangement of the certificate to provide more room for those items requesting dates and for describing how the injury occurred. New items have been added asking for information regarding traffic fatalities, the role of tobacco use in causing death, and whether female decedents were pregnant. Once approved by the Department of Health and Human Services, the new standard certificate will be made available to the states. Each state will have 2 years to adapt the U.S. Standard Certificate of Death to its use and to implement new state death certificates on January 1, 2003.     

Identification of the unidentified deceased and locating next of kin: experience with a UID web site page, Fulton County, Georgia

BACKGROUND: Medical examiner and coroner offices may face difficulties in trying to achieve identification of deceased persons who are unidentified or in locating next of kin for deceased persons who have been identified. The Fulton County medical examiner (FCME) has an office web site which includes information about unidentified decedents and cases for which next of kin are being sought. METHODS: Information about unidentified deceased and cases in need of next of kin has been posted on the FCME web site for 3 years and 1 year, respectively. FCME investigators and staff medical examiners were surveyed about the web site's usefulness for making identifications and locating next of kin. RESULTS: No cases were recalled in which the web site led to making an identification. Two cases were reported in which next of kin were located, and another case involved a missing person being ruled out as one of the decedents. The web site page is visited by agencies interested in missing and unidentified persons, and employees do find it useful for follow-up because information about all unidentified decedents is located and easily accessible, electronically, in a single location. CONCLUSIONS: Despite low yield in making identifications and locating next of kin, the UID web site is useful in some respects, and there is no compelling reason to discontinue its existence. It is proposed that UID pages on office web sites be divided into "hot" (less than 30 days, for example) and "warm" (31 days to 1 year, for example) cases and that cases older than a year be designated as "cold cases." It is conceivable that all unidentified deceased cases nationally could be placed on a single web site designed for such purposes, to remain in public access until identity is established and confirmed.     

Positional asphyxiation in adults. A series of 30 cases from the Dade and Broward County Florida Medical Examiner Offices from 1982 to 1990.

Over a 9-year period, 30 cases of positional (or postural) asphyxia were identified in the Dade and Broward County (Florida) Medical Examiner Offices. The victims had an average age of 50.6 years with no significant sex or racial differences as compared with the general medical examiner population. Chronic alcoholism or acute alcohol intoxication was a significant risk factor in 75% of cases and these had an average postmortem ethanol concentration of 0.24 g%. Signs of mechanical asphyxiation (petechiae and/or combined lung weights greater than 900 g) were present in 93% of cases. Victims were commonly (43%) found in a restrictive position producing hyperflexion of the head and neck. Two deaths involved restraint vests ("poseys") in elderly, demented, wheel-chair-confined victims. Scene photographs of the undisturbed decedent are extremely helpful in confirming a suspicion of postional asphyxia.     

Asthmatic deaths in the medical examiner's population

A study of people who die from asthma was performed. The case files of the Office of the Medical Examiner of Metropolitan Dade County in Miami, Florida, U.S.A., were examined during the 5-year period 1979-1983, and all autopsied cases in which bronchial asthma was the primary or contributory cause of death were collected. These 39 cases were then analyzed as to the age, race, sex, and cause of death of the victim. Additionally, the medication list of the victim, the location of the terminal incident, the scene circumstances, the presence of hospitalization at the terminal incident, and the histopathology of the lungs at autopsy were additionally observed. Essentially, the asthma victim the medical examiner sees at autopsy is an adult white male commonly dying in an acute asthmatic attack. Ninety percent (90%) of the deaths had medications noted with 20% having three or more medicines, one of which was a steroid. The terminal incident occurred at home most frequently with an acute attack or being found dead noted. Most victims received some form of terminal hospitalization. Histopathologically, classical "asthma findings" were noted approximately one half of the time.     

Variability in cancer death certificate accuracy by characteristics of death certifiers

Death certificates are the source for mortality statistics and are used to set public health goals. Accurate death certificates are vital in tracking outcomes of cancer. Deaths may be certified by physicians or other medical professionals, coroners, or medical examiners. Idaho is one of 3 states that participated in a Centers for Disease Control and Prevention-funded study to assess the concordance between cancer-specific causes of death and primary cancer site among linked cancer registry/death certificate data. We investigated variability in the accuracy of cancer death certificates by characteristics of death certifiers, including certifier type (physician vs coroner), physician specialty, years of experience as death certifier, and number of deaths certified. This study showed significant differences by certifier type/physician specialty in the accuracy of cancer mortality measured by death certificates. Nonphysician coroners had lower accuracy rates compared with physicians. Although nonphysician coroners certified less than 5% of cancer deaths in Idaho, they were significantly less likely to match the primary site from the cancer registry. Results from this study may be useful in the future training of death certifiers to improve the accuracy of death certificates and cancer mortality statistics.     

The validity of death certificates: routine validation of death certification and its effects on mortality statistics

The 3478 death certificates (7.1% of all annual death certificates) of this study comprise those national death certificates in 1995 submitted for validation to the panel representing both medical and nosological expertise. As such, it is highly selected and represents, from the nosological point of view, the most inconsistently filled-in portion of Finnish death certificates. The routine validation procedure is essentially based on exploitation of the extra medical information, i.e. the case history, on the Finnish death certificate form. Altogether, 2813 (80.9%) out of 3478 certificates could be adjusted at the primary panel session; the rest required further clarification. The re-assignment of cause of death by the panel and the impact of panel adjustments on the national mortality statistics is assessed here by comparing the initial death certification and the finally registered underlying cause of death grouped into ICD-9 major categories with special reference to the subcategories of neoplasm, cardiovascular disease (HVD) and unnatural death. A statistically significant decline (p<0.0001) in deaths, both in the category of symptoms, signs and ill-defined conditions and in the pulmonary circulation disease subcategory of HVD with 37.6 and 35.1%, respectively, was observed. The decrease of 11.1% in the benign or NUD neoplasm subcategory and the increase of 8.6 and 7.0% in the categories of endocrine disease, and musculo-skeletal and connective tissue disease, respectively, are essential observations as to the quality of the cause of death register. The effect on the HVD major category was practically nil. At the HVD-subcategorial level, a decrease of 14.0% for diseases of the veins and lymphatics and other circulatory diseases and an increase of 3.5% for hypertensive diseases (HYP) were the two next most obvious alterations to the diseases of the pulmonary circulation, but were without statistical significance. For ischaemic heart disease and other subcategories, the effects were minor. The unnatural deaths as a whole increased in the final statistics with only 0.9%. In the study data, categorial changes ranged from the decrease of 75.2% for symptoms, signs and ill-defined conditions to the increase of 77.3% for endocrine diseases. In conclusion, the Finnish death certificate form, death certification practices and cause of death validation procedure seem to serve the coding of causes of death for mortality statistics appropriately. The results of the study form a relevant reference background to evaluation of epidemiological studies on mortality.     

A Census of Medicolegal Death Investigation in the United States: A Need to Determine the State of our Nation’s Toxicology Laboratories and Their Preparedness for the Current Drug Overdose Epidemic

In 2007, the Bureau of Justice Statistics reported on 2004 data collected from the Census of Medical Examiner and Coroner Offices (CMEC). The CMEC was one of the first comprehensive reports on the state of the medicolegal death investigation system in the United States and included information on administration, expenditure, workload, specialized death investigations, records and evidence retention, and resources. However, the report did not include responses on questions that were related to toxicology such as specimen retention and type of testing. The purpose of this publication is to provide the community with toxicology laboratory-specific responses from nearly 2000 medical examiner and coroner (MEC) offices. Data obtained from a BJS CMEC public use dataset for any remaining information that was not reported in the 2007 BJS report were evaluated specific to the operation of toxicology laboratories within a MEC office or specific to toxicology testing. The CMEC includes information on average operating budget for MEC offices with internal or external toxicology services, budget for toxicology/microbiology services, respondents’ routine uses of toxicology analysis, toxicology specimen retention time, average turnaround times, use of computerized information management systems, and participation in federal data collections. These historical data begin to address the present state of our nation’s toxicology laboratories within the medicolegal death investigation system and their preparedness for the current drug overdose epidemic.
