    DEATH BY MEDICINE By Gary Null, PhD; Carolyn Dean MD, ND; Martin Feldman, MD; Debora Rasio, MD; and Dorothy Smith, PhD Abstract A definitive review and close reading of medical peer-review journals, and government health statistics shows that American medicine frequently causes more harm than good. The number of people having in- hospital, adverse drug reactions (ADR) to prescribed medicine is 2.2 million.1 Dr. Richard Besser, of the CDC, in 1995, said the number of unnecessary antibiotics prescribed annually for viral infections was 20 million. Dr. Besser, in 2003, now refers to tens of millions of unnecessary antibiotics.2, 2a The number of unnecessary medical and surgical procedures performed annually is 7.5 million.3 The number of people exposed to unnecessary hospitalization annually is 8.9 million.4 The total number of iatrogenic deaths shown in the following table is 783,936. It is evident that the American medical system is the leading cause of death and injury in the United States. The 2001 heart disease annual death rate is 699,697; the annual cancer death rate, 553,251.5 TABLES AND FIGURES (see Section on Statistical Tables and Figures, below, for exposition) Table 1: Estimated Annual Mortality and Economic Cost of Medical Intervention Condition Deaths Cost Author Adverse Drug Reactions 106,000 $12 billion Lazarou1 Suh49 Medical error 98,000 $2 billion IOM6 Bedsores 115,000 $55 billion Xakellis7 Barczak8 Infection 88,000 $5 billion Weinstein9 MMWR10 Malnutrition 108,800 -------- Nurses Coalition11 Outpatients 199,000 $77 billion Starfield12 Weingart112 Unnecessary Procedures 37,136 $122 billion HCUP3,13 Surgery-Related 32,000 $9 billion AHRQ85 TOTAL 783,936 $282 billion We could have an even higher death rate by using Dr.

Ford, Ph.D., MPH Palmieri, P. A., Peterson, L. T., and Ford, E. W. (2008). Technological Iatrogenesis: New Risks Necessitate Heightened Management Awareness. Journal of Healthcare Risk Management. 27(4), pp. 19 - 24. Made available courtesy of Wiley-Blackwell and the American Society for Healthcare Risk Management: http://www.ashrm.org/ *** Note: Figures may be missing from this format of the document *** Note: The definitive version is available at http://www3.interscience.wiley.com/ Abstract: Iatrogenesis is a term typically reserved to express the state of ill health or the adverse outcome resulting from a medical intervention, or lack thereof. Three types of iatrogenesis are described in the literature: clinical, social and cultural. This paper introduces a fourth type, technological iatrogenesis, or emerging errors stimulated by the infusion of technological innovations into complex healthcare systems. While health information technologies (HIT) have helped to make healthcare safer, this has also produced contemporary varieties of iatrogenic errors and events. The potential pitfalls of technological innovations and risk management solutions to address these concerns are discussed. Specifically, failure mode effect analysis and root cause analysis are discussed as opportunities for risk managers to prevent problems and avert errors from becoming sentinel events. Article: INTRODUCTION Millennia ago, Hippocrates recognized the potential for injuries that arise despite the well intended actions of healers. The directive primum non nocere (“first, do no harm”) is a central tenet in medicine.

  • Iatrogenesis Prescription Drugs in Psychiatric Disorders
    Activity Preview Iatrogenesis Prescription Drugs in Psychiatric Disorders Activity Type On-Demand Overview The DSM 5 diagnostic criteria always require that general medical conditions or drug-induced symptoms are ruled out before a clinician diagnosis a patient with having a primary psychiatric disorder. There are in fact many psychiatric symptoms triggered not only by recreational drugs, but also by prescription medications that are widely used in primary care and specialized care. Medical conditions associated with depression include endocrinopathies, neurologic disorders, vitamin deficiencies and cardiovascular disease. Medical disorders associated with anxiety include hyperthyroidism, COPD, asthma, diabetes, chronic pain, irritable bowel, pheochromocytoma, Lyme disease, head trauma, vascular dementia, Parkinson’s disease, Lupus, rheumatoid arthritis, loss of estrogen and electrolyte imbalance. Symptoms of mania can be associated with infections, epilepsy, stroke, brain tumors, influenza and hemodialysis. Psychotic symptoms can result from CNS diseases, toxins, autoimmune diseases, chromosomal abnormalities, infectious diseases, nutritional deficits, endocrine disorders and metabolic diseases. On the other hand, prescription drugs can also generate psychopathology symptoms. Steroids are associated with psychosis, mania, depression and anxiety. Similar symptoms can be associated with ACE inhibitors, anticholinergic drugs, anticonvulsants, barbiturates, benzodiazepines, beta-adrenergic drugs, calcium channel blockers, dopamine agonists
