    Disease-a-month : DM 2016 Mar

    Authors: Thompson TM, Leikin JB
    We previously reported the financial data for the first 5 years of one of the author's medical toxicology practice. The practice has matured; changes have been made. The practice is increasing its focus on office-based encounters and reducing hospital-based acute care encounters. We report the reimbursement rates and other financial metrics of the current practice. Financial records from October 2009 through September 2013 were reviewed. This is a period of 4 fiscal years and represents the currently available financial data. Charges, payments, and reimbursement rates were recorded according to the type and setting of the medical toxicology encounter: forensic consultations, outpatient clinic encounters, nonpsychiatric inpatient consultations, emergency department (ED) consultations, and inpatient psychiatric consultations. All patients were seen regardless of ability to pay or insurance status. The number of billed Current Procedural Terminology (CPT) codes for office-based encounters increased over the study period; the number of billed CPT codes for inpatient and ED consultations reduced. Office-based encounters demonstrate a higher reimbursement rate and higher payments. In the fiscal year (FY) of 2012, office-based revenue exceeded hospital-based acute care revenue by over $140,000 despite a higher number of billed CPT encounters in acute care settings, and outpatient payments were 2.39 times higher than inpatient, inpatient psychiatry, observation unit, and ED payments combined. The average payment per CPT code was higher for outpatient clinic encounters than inpatient encounters for each fiscal year studied. There was an overall reduction in CPT billing volume between FY 2010 and FY 2013. Despite this, there was an increase in total practice revenue. There was no change in payor mix, practice logistics, or billing/collection service company. In this medical toxicology practice, office-based encounters demonstrate higher reimbursement rates and overall payments compared to inpatient and ED consultations. While consistent with our previous studies, these differences have been accentuated. This study demonstrates the results of changes to the practice--reduced inpatient/ED consultations and increased outpatient encounters. These practice changes resulted in higher overall revenue despite a lower patient volume. In this analysis, the office-based practice of medical toxicology has higher reimbursement rates, nearly 2.5 times higher, when compared to hospital-based acute care consultations.

  • Irritants and corrosives.

    Emergency medicine clinics of North America 2015 Feb

    Authors: Tovar R, Leikin JB
    This article reviews toxic chemicals that cause irritation and damage to single and multiple organ systems (corrosion) in an acute fashion. An irritant toxic chemical causes reversible damage to skin or other organ system, whereas a corrosive agent produces irreversible damage, namely, visible necrosis into integumentary layers, following application of a substance for up to 4 hours. Corrosive reactions can cause coagulation or liquefaction necrosis. Damaged areas are typified by ulcers, bleeding, bloody scabs, and eventual discoloration caused by blanching of the skin, complete areas of alopecia, and scars. Histopathology should be considered to evaluate questionable lesions.

  • Incarceration medical problems.

    Disease-a-month : DM 2014 May

    Although cholinesterase inhibitors have been frequently used in the treatment of Alzheimer disease, its effects on serum cholinesterase concentrations have been rarely described. We described significant depression of serum cholinesterase levels due to cholinesterase inhibitor toxicity from redundant use of donepezil and rivastigmine in a 78-year-old man. Recovery of serum cholinesterase level was noted upon drug discontinuation and cholinergic symptom resolution. Serum cholinesterase level can be used as a biomarker for central cholinesterase inhibitor toxicity.

    Nutmeg is a commonly consumed spice. The toxic effects of nutmeg have been purported to be due mainly to myristicin oil. Prior poison center series of nutmeg exposures show very few unintentional exposures of nutmeg to children younger than 13. Case series from these centers did not record drug exposures combined with nutmeg. This study is a review of Illinois Poison Center (IPC) data regarding nutmeg exposures from January of 2001 to December 2011. The goal of this study was to compare the Illinois data to the literature as well as look for current trends in nutmeg poisonings. The data were extracted using the code for hallucinogenic plants in the IPC database, and poisonings unrelated to nutmeg exposure were eliminated. Medical outcomes were noted as recorded. Thirty-two cases of nutmeg ingestion were reported. Of the 17 (53.1 %) unintentional exposures, 10 subjects (58.8 %) were under the age of 13. Four of the exposures in children under the age of 13 were ocular exposures. Fifteen exposures (46.9 %) were intentional exposures. Of these intentional exposures, five (33.3 %) were recorded to have combined drug intoxication. All of these were between the ages of 15 and 20. One patient with polypharmaceutical exposure required ventilatory support in the hospital. Our study shows an unexpected percentage of unintentional exposures in juveniles under the age of 13, out of the total exposures to nutmeg. Mixing of nutmeg with other drugs was seen and required more intervention in adolescents. More education about these two factors, i.e., nutmeg exposures as intentional polypharmacy in adolescents and unintentional exposures in young children, is advised.
