It would be difficult to overstate the importance of death certificates--especially in an era of increasing reliance forward evidence-based medicine (EBM)--yet physicians receive inadequate training in this important area, and their performance onward this task remains less than ideal. (1-3)

For small and large populations, the definitive assessment of our succes at prolonging life is the age-adjusted mortality rate, and the primary tool for measuring mortality rates is the death certificate. In addition, death certificates minister to other essential functions (National Center for Health Statistics, Center for Disease rule and Prevention [CDC] online at http://wwwcdcgov/nchs) including setting national, regional, statewide, and local priorities for funding, research, and interventions (4); settling estates, closing bank accounts, selling stocks and cords and determining insurance and pension benefits; providing evidence in court cases; and providing issue data for major research studies.

Accurate completion is essential to make secure the usefulness and reliability of the individual death certificate as well as the aggregate mortality statistics derived from it, still data suggest that cause and manner of death are not reported in a consistent fashion. In undivided recent survey in which 198 experienced and trained medical examiners determined the manner of death for 23 scenarios, there was more than 90 percent agreement for barely four scenarios, 13 scenarios had between 60 and 90 percent agreement, and the remaining six scenarios had les than 60 percent agreement. (5)

While the cause of death may be difficult to agree upon sometimes, most problems with death certificates stipe from failure to complete them correctly. still these errors are avoidable. Myers and Farquhar showed that major errors forward death certificates dropped from 329 to 157 percent (P = 01) after primary care physicians attended a 75-minute educational seminar. (6) Lakkireddy and colleagues also showed that improved completion of death certificates correlated with specific training in that skill. (7)

Physicians without training in death certificates may not plane understand the correct definitions of the following terms:

Manner of Death. The connection or circumstances that surround the death; examples include accident, suicide, homicide, and natural causes. Typically, physicians can alone certify natural deaths, while the coroner or medical examiner must make the final determination for suicides, homicides, and uniform accidents as common as unsalable article overdoses or falls.

Immediate Cause of Death. The proximate, greatest in number recently developed, final diagnostic entity causing the death. Must be a specific etiology (eg Escherichia coli sepsis, acute renal failure, hypoxemia), not a general universal such as old age or spells like cardiac arrest or organ rule failure that can have multiple etiologies.

Underlying Cause of Death. This is the fundamental, original, foundational diagnosis or condition from which the remainder of the etiologic arrangement springs; it is the diagnosis of longest duration in the chain of ends leading directly to death. Examples include human immunodeficiency virus infection (the underlying cause of acquired immunodeficiency syndrome) coronary artery atherosclerosis, and metastatic breast cancer. The description must be specific enough to make clear for what purpose the intermediate (if any) and immediate causes of death developed

In almost all cases, a time-linked chain of causation can be established, in the same state [i]or[/i] condition that the immediate cause of death was a event of a somewhat longer-duration diagnosis, which in employ was a consequence of an flat longer-duration diagnosis, and so forward through as many or small in number intermediate causes as necessary until reaching the faithful underlying cause of death. Other significant, however not directly linked, conditions must be listed separately.

customary errors in completion of death certificates include incorrect attribution of the immediate cause of death, listing causes in an incorrect or illogical order, multiple competing immediate causes of death, poor match between cause and manner of death, and failure to identify the steady underlying cause or causes. (38) Consider these examples:

* Manner: Natural. Cause: Ventricular fibrillation, to be paid to acute myocardial infarction, owing to coronary artery thrombosis, as a result of atherosclerotic coronary artery disease. [Satisfactory: Note plausible chain of causality.]

* Manner: Natural. Cause: Pneumonia, to be paid to a hip fracture, fit to chronic obstructive pulmonary disease, as a issue of diabetes mellitus and hypertension. [Unsatisfactory: No causal chain; possibly competing immediate causes; etiology of pneumonia unspecified; hip fracture is usually accidental, not natural; hypertension (in this case) and other diagnoses not in the direct causal chain should be listed in Part II, Other Significant Conditions.]

* Manner: Natural. Cause: Staphylococcal sepsis, proper to methicillin-resistant staphylococcal pneumonitis, owed to chronic aspiration, secondary to swallowing dysfunction, as a chain of cause and effect of Parkinson's disease. [Satisfactory: Note clear and plausible chain of causality.]
