Personality, High-Risk Behaviors, and Elevated Risk of Unintentional Deaths Related to Drug Poisoning Among Individuals With Spinal Cord Injury.

OBJECTIVE: To identify risk and protective factors for unintentional death related to drug poisoning from prescription medications, including opioid-related deaths, and death due to all other causes among participants with spinal cord injury (SCI). DESIGN: Prospective cohort study. SETTING: Large specialty hospital in the southeastern United States. PARTICIPANTS: Two cohorts of SCI participants (N=3070) (>18y) with chronic (>1y) traumatic SCI. Cohort 1 was enrolled in 1997-1998 (n=1386), and cohort 2 was enrolled in 2007-2009 (n=1684). INTERVENTIONS: N/A. MAIN OUTCOME MEASURES: Participants completed self-report assessments including multiple behavioral variables (alcohol, smoking, prescription medication), as well as the Zuckerman-Kuhlman Personality Questionnaire (ZKPQ). The primary outcome is unintentional death related to drug poisoning. Mortality status was determined as of December 31, 2014, using the National Death Index. The Centers for Disease Control guidelines were used for classifying participants into 3 groups: (1) unintentional death related to drug poisoning, (2) other death, and (3) alive. RESULTS: There were 690 deaths (23%), including 24 unintentional deaths related to drug poisoning (11 from opioids). Binge drinking, medication usage total score, and impulsive-sensation seeking were risk factors for unintentional death related to drug poisoning, whereas the ZKPQ activity scale was protective. Risk factors for other causes of death included older age, greater injury severity, being nonambulatory, regular smoker, medication use total score, and greater neuroticism-anxiety scale scores. CONCLUSIONS: Unintentional deaths related to prescription drug overdose are associated with a set of risk factors that differs in meaningful ways from risk of death due to other causes after SCI, and these differences hold the key to prevention strategies.

The Feasibility and Clinical Utility of Conducting a Confidential Inquiry Into Suicide in Southwestern Ontario.

BACKGROUND AND AIMS: Given the effectiveness of the National Confidential Inquiry into Suicide and Homicide by People with Mental Illness (NCI) in the UK, the present study evaluated this approach in Southwestern Ontario. A systematic confidential examination of suicides in Ontario was developed to guide quality improvement of services and suicide prevention. METHOD: A 3-year case series of consecutive suicides in Southwestern Ontario identified by the Office of the Chief Coroner was compiled. Clinicians who provided care to suicide decedents completed an online confidential suicide questionnaire offered through a secured portal. RESULTS: A total of 476 suicide cases were analyzed. In all, 270 invitations to clinicians were sent, 237 (87.8%) responded to the invitation and 187 (69.3%) completed the online questionnaire. The majority of the suicide decedents (54.6%, n = 260), were between the ages of 40 and 64 (x = 47.2, SD = 17.1), White (91.4%, n = 416), single (34.2%, n = 439), and male (74.4%, n = 476). Of the 86 cases of self-poisoning, prescription medications were used in 66.3%. Almost two thirds of decedents visited the clinician in the month prior to their death. LIMITATIONS: The results of the survey were drawn from suicides in Southwestern Ontario and generalizing these findings should be done with caution. CONCLUSION: This study highlights (a) the value of the clinicians' survey to identify gaps in clinical services and (b) the necessity of improvements in suicide risk assessment/management and restriction of prescription medications.

Medication organizers (pill minders) increase the risk for unintentional pediatric ingestions.

OBJECTIVE: Medication organizers may help improve medication compliance; however, they may increase the risk of having an unintentional pediatric exposure. The objective of this study was to measure the association between a pediatric emergency department (ED) visit for an unintentional pharmaceutical ingestion and the use of a medication organizer in the household. METHODS: This was a cross-sectional case control study at a tertiary care children's hospital ED. Cases included subjects <6 years of age who were evaluated in the ED for an unintentional pharmaceutical ingestion. The control group presented to the ED for a non-injury complaint and was matched using age and sex. RESULTS: The unadjusted odds ratio (OR) of risk for unintentional pharmaceutical ingestion with use of a medication organizer was 2.0 (95% CI, 1.3, 2.9). After adjusting for the presence of prescription medications in the home, the OR of risk for ingestion remained statistically significant at 1.8 (95% CI, 1.1, 2.7). The child obtained the exposure medication from the medication organizer in 63% of cases where a medication organizer was present in the home. Cases were more likely to have knowledge of, and previous contact with poison control centers (PCC) than non-injury controls. Overall, a large number of caregivers (36%) did not have any knowledge of PCC. There were also differences in smoking and use of seat belts between cases and controls. CONCLUSIONS: The use of medication organizers may be a risk factor for unintentional pediatric pharmaceutical ingestions, even when controlling for the use of prescription medications in the home. Further research is needed to evaluate the specific role of medication organizers, and subsequently, improve prevention strategies.

Number of medications and adverse drug events by unintentional poisoning among older adults in consideration of inappropriate drug use: a Swedish population-based matched case-control study.

PURPOSE: This national, population-based study aims to determine the association between the number of prescribed medications and adverse drug events (ADE) by unintentional poisoning and examine this risk when known indicators of inappropriate drug use (IDU) are accounted for. METHODS: We employed a matched case-control design among people living in Sweden who were 50 years and older. Cases experiencing an ADE by unintentional poisoning resulting in hospitalization or death (n = 5336) were extracted from the National Health and Death Registers from January 2006 to December 2009. Four controls per case matched by age, sex and residential area were randomly selected among those without an ADE (n = 21,344). Prescribed medications dispensed during the 4-month period prior to the ADE were identified via the Swedish Prescribed Drug Register and coded according to the number of different dispensed medications (NDDM) (0 to 10 medications) and IDU indicators (one single-drug, and three drug-combinations). Conditional logistic regression was used. RESULTS: Each of the IDU indicators was significantly associated with very high risks of ADE. For NDDM, we found a lower but graded positive association from two to ten or more medications (adjusted OR, 1.5; 95% CI, 1.2-1.8). Exclusion of IDU from the NDDM decreased the risk of ADE, but the effects remained significant for three or more medications (adjusted OR excl. IDU, 1.5; 95% CI, 1.2-2.0). CONCLUSION: At population level, the number of different dispensed medications starting from three or more remains associated with ADE even after adjusting for known IDUs. Clinicians and patients need to be made aware of the increased likelihood of serious ADE, not only in case of documented inappropriate medications but also in the case of an increasing number of medications.

National Trends in Hospitalizations for Opioid Poisonings Among Children and Adolescents, 1997 to 2012.

Importance: National data show a parallel relationship between recent trends in opioid prescribing practices and hospitalizations for opioid poisonings in adults. No similar estimates exist describing hospitalizations for opioid poisonings in children and adolescents. Objective: To describe the incidence and characteristics of hospitalizations attributed to opioid poisonings in children and adolescents. Design, Setting, and Participants: Retrospective analysis of serial cross-sectional data from a nationally representative sample of US pediatric hospital discharge records collected every 3 years from January 1, 1997, through December 31, 2012. The Kids' Inpatient Database was used to identify 13 052 discharge records for patients aged 1 to 19 years who were hospitalized for opioid poisonings. Data were analyzed within the collection time frame. Main Outcomes and Measures: Poisonings attributed to prescription opioids were identified by codes from the International Classification of Diseases, Ninth Revision, Clinical Modification. In adolescents aged 15 to 19 years, poisonings attributed to heroin were also identified. Census estimates were used to calculate incidence per 100 000 population. The Cochran-Armitage test for trend was used to assess for changes in incidence over time. Results: From 1997 to 2012, a total of 13 052 (95% CI, 12 500-13 604) hospitalizations for prescription opioid poisonings were identified. The annual incidence of hospitalizations for opioid poisonings per 100 000 children aged 1 to 19 years rose from 1.40 (95% CI, 1.24-1.56) to 3.71 (95% CI, 3.44-3.98), an increase of 165% (P for trend, <.001). Among children 1 to 4 years of age, the incidence increased from 0.86 (95% CI, 0.60-1.12) to 2.62 (95% CI, 2.17-3.08), an increase of 205% (P for trend, <.001). For adolescents aged 15 to 19 years, the incidence increased from 3.69 (95% CI, 3.20-4.17) to 10.17 (95% CI, 9.48-10.85), an increase of 176% (P for trend, <.001). In this age group, poisonings from heroin increased from 0.96 (95% CI, 0.75-1.18) to 2.51 (95% CI, 2.21-2.80), an increase of 161% (P for trend, <.001); poisonings involving methadone increased from 0.10 (95% CI, 0.03-0.16) to 1.05 (95% CI, 0.87-1.23), an increase of 950% (P for trend, <.001). Conclusions and Relevance: During the course of 16 years, hospitalizations attributed to opioid poisonings rose nearly 2-fold in the pediatric population. Hospitalizations increased across all age groups, yet young children and older adolescents were most vulnerable to the risks of opioid exposure. Mitigating these risks will require comprehensive strategies that target opioid storage, packaging, and misuse.

Perfil das exposições a medicamentos por mulheres em idade reprodutiva atendidas por um Centro de Informações Toxicológicas / Profile of exposure to medication among women of reproductive age attended in a Toxicologial Information Center

O objetivo deste artigo é descrever os dados epidemiológicos referentes às exposições a medicamentos por mulheres em idade fértil atendidas por um Centro de Informações Toxicológicas. Realizou-se um estudo com mulheres em idade fértil, expostas a medicamentos entre 2007 e 2011. Foram estudadas variáveis relacionadas às pacientes, à ocorrência e ao medicamento envolvido, totalizando 777 notificações. Os dados foram obtidos do Sistema de Informação de Agravos de Notificação e processadas com o uso do programa Epi Info. A maioria das ocorrências (90,5%) foi intencional, em 33,7% dos casos foram utilizados de dois a três medicamentos e a frequência de hospitalização foi de 35,6%. Os medicamentos com atuação no Sistema Nervoso Central foram responsáveis por 59,9% das ocorrências, destacando-se os antiepilépticos (21,2%) e os antidepressivos (20,7%). Os principais fatores associados à hospitalização das pacientes foram: demora no atendimento após a ocorrência da exposição, pacientes com nível superior, contato com dois ou mais medicamentos e exposições a antiepilépticos e antidepressivos. Os resultados obtidos mostraram que as exposições a medicamentos representam um grave problema à saúde de mulheres em idade fértil e contribuem para o aumento das internações hospitalares.

The scope of this article is to analyze the epidemiological data relating to exposure to medication among women of reproductive age attended at a Toxicology Information Center. A study was conducted among women of reproductive age exposed to medication between 2007 and 2011. The variables relating to the patients, the occurrence and the medication involved were studied in a total of 777 notified cases. Data was collected from Aggravated Injury Notification System forms and processed on Epi Info for Windows software. The majority of the occurrences (90.5%) was intentional, 33.7% of theses incidents involved the intake of 2 or 3 types of drugs by the patients and the percentile of hospitalization was 35.6%. Drugs acting on the central nervous system were responsible for 59.9% of the incidents, and antidepressants (21.3%) and anti-epileptics (21.2%) were most commonly involved. The main factors associated with hospitalization were: delayed medical rescue after exposure, patients with higher education, ingestion of 2 or 3 types of drugs and exposure to anti-epileptics and antidepressants. Data from this study showed that exposure to medication is a serious health problem for women of reproductive age and it contributes to the increase in the number of hospitalizations.

Prescription opioid mortality trends in New York City, 1990-2006: examining the emergence of an epidemic.

BACKGROUND: The drug overdose mortality rate tripled between 1990 and 2006; prescription opioids have driven this epidemic. We examined the period 1990-2006 to inform our understanding of how the current prescription opioid overdose epidemic emerged in urban areas. METHODS: We used data from the Office of the Chief Medical Examiner to examine changes in demographic and spatial patterns in overdose fatalities induced by prescription opioids (i.e., analgesics and methadone) in New York City (NYC) in 1990-2006, and what factors were associated with death from prescription opioids vs. heroin, historically the most prevalent form of opioid overdose in urban areas. RESULTS: Analgesic-induced overdose fatalities were the only types of overdose fatalities to increase in 1990-2006 in NYC; the fatality rate increased sevenfold from 0.39 in 1990 to 2.7 per 100,000 persons in 2006. Whites and Latinos were the only racial/ethnic groups to exhibit an increase in overdose-related mortality. Relative to heroin overdose decedents, analgesic and methadone overdose decedents were more likely to be female and to concurrently use psychotherapeutic drugs, but less likely to concurrently use alcohol or cocaine. Analgesic overdose decedents were less likely to be Black or Hispanic, while methadone overdose decedents were more likely to be Black or Hispanic in contrast to heroin overdose decedents. CONCLUSIONS: The distinct epidemiologic profiles exhibited by analgesic and methadone overdose fatalities highlight the need to define drug-specific public health prevention efforts.

Risk factors for prescription opioid-related death, Utah, 2008-2009.

OBJECTIVE: Utah prescription opioid death rates increased nearly fivefold during 2000-2009. Inadequate understanding of risk factors hinders prevention. The goal of this study was to determine risk factors for prescription opioid death in Utah. DESIGN: Case-control study. Cases were 254 Utah decedents with ≥1 prescription opioid causing death during 2008-2009 with nonintentional manner of death (information obtained via next-of-kin interviews). Controls were 1,308 Utah 2008 Behavioral Risk Factor Surveillance System respondents who reported prescription opioid use during the previous year. OUTCOME MEASURES: Exposure prevalence ratios (EPRs) for selected characteristics and confidence intervals (CIs) were calculated. RESULTS: Decedents were more likely than the comparison group to have used prescription pain medication more than prescribed (52.9% vs 3.2%; EPR, 16.5; 95% CI, 9.3-23.7), obtained prescription pain medication from nonprescription sources (39.6% vs 8.3%; EPR, 4.8; 95% CI, 3.6-6.0), smoked daily (54.5% vs 9.7%; EPR, 5.6; 95% CI, 4.4-6.9), not graduated high school (18.5% vs 6.2%; EPR, 3.0; 95% CI, 2.0-3.9), and been divorced or separated (34.6% vs 9.4%; EPR, 3.7; 95% CI, 3.0-4.4). Decedents were more likely to have had chronic pain than the comparison group (94.2% vs 31.6%; EPR, 3.0; 95% CI, 2.7-3.3). CONCLUSIONS: Use of pain medication outside prescription bounds was a risk factor for death. However, decedents were more likely to have had chronic pain, and the majority of both groups had obtained pain medication by prescription. Other factors (e.g., smoking status) might also play important roles in prescription opioid-related death. Prescribers should screen chronic pain patients for risk factors.

Association of mental health disorders with prescription opioids and high-risk opioid use in US veterans of Iraq and Afghanistan.

CONTEXT: Record numbers of Iraq and Afghanistan veterans survive their war injuries and yet continue to experience pain and mental health problems, particularly posttraumatic stress disorder (PTSD). Little is known about the association of mental health disorders and prescription opioid use. OBJECTIVE: To investigate the effect of mental health disorders, particularly PTSD, on risks and adverse clinical outcomes associated with prescription opioid use. DESIGN: Retrospective cohort study involving 141,029 Iraq and Afghanistan veterans who received at least 1 non-cancer-related pain diagnosis within 1 year of entering the Department of Veterans Affairs (VA) health care system from October 1, 2005, through December 31, 2010. MAIN OUTCOME MEASURES: Independent association of mental health disorders and the prescription of opioids, higher risk opioid use, and adverse clinical outcomes (eg, accidents and overdose) within 1 year of receiving a pain-related diagnosis. RESULTS: A total of 15,676 veterans were prescribed opioids within 1 year of their initial pain diagnosis. Compared with 6.5% of veterans without mental health disorders, 17.8% (adjusted relative risk [RR], 2.58; 95% CI, 2.49-2.67) of veterans with PTSD and 11.7% (adjusted RR, 1.74; 95% CI, 1.67-1.82) with other mental health diagnoses but without PTSD were significantly more likely to receive opioids for pain diagnoses. Of those who were prescribed pain medication, veterans with PTSD were more likely than those without mental health disorders to receive higher-dose opioids (22.7% vs 15.9%, adjusted RR, 1.42; 95% CI, 1.31-1.54), receive 2 or more opioids concurrently (19.8% vs 10.7%, adjusted RR, 1.87; 95% CI, 1.70-2.06), receive sedative hypnotics concurrently (40.7% vs 7.6%, adjusted RR, 5.46; 95% CI, 4.91-6.07), or obtain early opioid refills (33.8% vs 20.4%; adjusted RR, 1.64; 95% CI, 1.53-1.75). Receiving prescription opioids (vs not) was associated with an increased risk of adverse clinical outcomes for all veterans (9.5% vs 4.1%; RR, 2.33; 95% CI, 2.20-2.46), which was most pronounced in veterans with PTSD. CONCLUSION: Among US veterans of Iraq and Afghanistan, mental health diagnoses, especially PTSD, were associated with an increased risk of receiving opioids for pain, high-risk opioid use, and adverse clinical outcomes.

From pesticides to medicinal drugs: time series analyses of methods of self-harm in Sri Lanka.

OBJECTIVE: To explore if recent changes in methods of self-harm in Sri Lanka could explain the decline in the incidence of suicide. METHODS: Time series analyses of suicide rates and hospitalization due to different types of poisoning were carried out. FINDINGS: Between 1996 and 2008 the annual incidence of hospital admission resulting from poisoning by medicinal or biological substances increased exponentially, from 48.2 to 115.4 admissions per 100,000 population. Over the same period, annual admissions resulting from poisoning with pesticides decreased from 105.1 to 88.9 per 100,000. The annual incidence of suicide decreased exponentially, from a peak of 47.0 per 100,000 in 1995 to 19.6 per 100,000 in 2009. Poisoning accounted for 37.4 suicides per 100,000 population in 1995 but only 11.2 suicides per 100,000 in 2009. The case fatality rate for pesticide poisoning decreased linearly, from 11.0 deaths per 100 cases admitted to hospital in 1997 to 5.1 per 100 in 2008. CONCLUSION: Since the mid 1990s, a trend away from the misuse of pesticides (despite no reduction in pesticide availability) and towards increased use of medicinal and other substances has been seen in Sri Lanka among those seeking self-harm. These trends and a reduction in mortality among those suffering pesticide poisoning have resulted in an overall reduction in the national incidence of accomplished suicide.

Perfil da mortalidade por intoxicação com medicamentos no Brasil, 1996-2005: retrato de uma década / Profile of mortality by intoxication with medication in Brazil, 1996-2005: portrait of a decade

A ocorrência de óbitos por intoxicação com medicamentos tem sido considerada um dos agravos de saúde pública. O estudo descreve o perfil epidemiológico da mortalidade por intoxicação com medicamentos na população do Brasil entre 1996 e 2005. Realizou-se um estudo descritivo com dados do Sistema de Informações sobre Mortalidade do Ministério da Saúde. Selecionaram-se os óbitos segundo a Classificação Internacional de Doenças (CID-10). Foram identificados 4.403 óbitos ocorridos em homens (53,9 por cento), solteiros (53,7 por cento) e faixa etária de 20-39 anos (44,0 por cento). A maioria dos óbitos foi por autointoxicação intencional por anticonvulsivantes, sedativos, antiparkinsonianos e psicotrópicos. A taxa padronizada de mortalidade foi maior na região Centro-Oeste e os Anos Potenciais de Vida Perdidos aumentou durante o período estudado em 15,50 por cento. O estudo apresentou as características e variações na mortalidade por intoxicação com medicamentos no Brasil que pode ser um reflexo do padrão de consumo dos medicamentos no país atrelado à necessidade de aprimoramento das políticas de vigilância sanitária.

The occurrence of deaths caused by intoxication with medication have been considered a worsening public health problem. The study describes the epidemiological profile of medication-related intoxication in the general Brazilian population from 1996 to 2005. A descriptive study was conducted with mortality data obtained from the Mortality Information System of the Brazilian Ministry of Health. Deaths were selected according to the codes of the International Classification of Diseases (ICD-10). A total of 4,403 deaths were found inn males (53.9 percent), bachelors (53.7 percent) and the 20 to 39 year-old age bracket (44 percent). The majority of deaths were caused by intentional self-intoxication using anticonvulsants, sedatives, antiparkinsonians and psychotropics. The standardized mortality rate was higher in the Midwest region and Potential Life-Years Lost increased by 15.5 percent. The study showed the characteristics and variations in mortality by intoxication with medication in Brazil, which can be a reflex of the medication consumption patterns of the country, indicating the need for enhancement of sanitary vigilance policies.

Prescription of opioid analgesics and related harms in Australia.

OBJECTIVE: To document trends in: (i) prescribing of morphine and oxycodone; (ii) hospital separations for overdose; (iii) presentations for treatment of problems associated with these drugs; and (iv) oxycodone-related mortality data in Australia. DESIGN AND SETTING: Cross-sectional study analysing prescriptions for morphine and oxycodone based on figures adjusted using Australian Bureau of Statistics estimated resident population and prospectively collected data from: (i) the National Hospital Morbidity Database on hospital separations primarily attributed to poisoning with opioids other than heroin ("other opioids"); (ii) the Alcohol and Other Drug Treatment National Minimum Data Set for treatment episodes where morphine or oxycodone were the primary or other drugs of concern; (iii) the National Coronial Information System on deaths where oxycodone was the underlying cause of death or a contributory factor. MAIN OUTCOME MEASURES: Population-adjusted numbers of (i) prescriptions for morphine and oxycodone by 10-year age group, (ii) hospital separations for "other opioid" poisoning, and (iii) treatment episodes related to morphine or oxycodone; and (iv) number of oxycodone-related deaths. RESULTS: Prescriptions for morphine declined, while those for oxycodone increased. Prescriptions for both were highest among older Australians. Hospital separations for "other opioid" poisoning doubled between the financial years 2005-06 and 2006-07. Treatment episodes for morphine remained stable, while those for oxycodone increased. There were 465 oxycodone-related deaths recorded during 2001-2009. CONCLUSIONS: Oxycodone prescriptions in Australia have increased, particularly among older Australians. The increase may, in part, reflect appropriate prescribing for pain among an ageing population. However we are unable to differentiate non-medical use from appropriate prescribing from this data. In comparison to heroin, the morbidity and mortality associated with oxycodone is relatively low in Australia. There is a continued need for comprehensive training of general practitioners in assessing patients with chronic non-malignant pain and prescribing of opioids for these patients, to minimise the potential for harms associated with use of these medications.

Pacientes atendidos en un Centro Toxicológico de Venezuela / Patients attended at a Venezuelan Toxicology Centre

Objetivo Caracterizar los pacientes atendidos en un Centro Toxicológico de la Región Centro Occidental de Venezuela. Métodos Se realizó un estudio descriptivo y transversal. La población estuvo constituida por 1 938 pacientes registrados durante los años 2006 y 2007 en las planillas de recolección de datos del Centro. Resultados Del total de pacientes registrados en las planillas del Centro Toxicológico en el bienio 06-07, 57,4 por ciento consultaron en el 2006. La edad media de los pacientes atendidos fue de 19 años en el 2006 y 20 años en el 2007, con atención tanto de niños como de adultos, siendo el sexo masculino el que mayormente consultó (55,4 por ciento). La causa de consulta más frecuente en el lapso estudiado para ambos sexos fue emponzoñamientos, de los cuales más del 40 por ciento fue por serpientes del género Bothrops, en hombres la segunda causa fue intoxicación por plaguicidas (20,6 por ciento) y en mujeres intoxicación medicamentosa con un 26,6 por ciento. El municipio del Estado Lara con mayor afluencia de pacientes fue Iribarren con 47,8 por ciento, y durante los dos años se atendieron 95 pacientes (4,9 por ciento) que provenían de Estados vecinos (Portuguesa y Yaracuy principalmente). Conclusiones Se espera que con el presente estudio se implementen programas especiales de educación y atención para las patologías diagnosticadas con mayor frecuencia, así como los correctivos considerando los riesgos individuales y colectivos en las diferentes zonas geográficas del Estado Lara.

Objective Characterising patients attended at a toxicological centre in the central western area of Venezuela (the state of Lara). Methods This was a descriptive/cross-sectional study. The population consisted of 1,938 patients who registered during 2006 and 2007; data was collected from the Centre's data collection forms. Results 57.4 percent of the patients recorded on the toxicological centre's forms during 2006 and 2007 consulted during 2006. The patients' average age was 19 during 2006 (including adults and teenagers) and 20 during 2007. Males most often attended the centre (55.4 percent). The most common cause for consultation was poisoning from snake bite, more than 40 percent of the cases being caused by Bothrops. Pesticide intoxication was the second cause for male consultation (20.6 percent); female medication poisoning accounted for 26.6 percent. Iribarren County had the highest consultation rate in the State of Lara (47.8 percent of cases). 95 patients (4.9 percent) came from neighbouring States (Portuguesa and Yaracuy) during the two years this study lasted. Conclusions It is hoped that this study will lead to special education and attention programmes for the most commonly diagnosed pathologies being implemented with greater frequency, as well as corrective action being taken regarding individual and collective risk in the state of Lara's different geographical areas.

Factors associated with mortality in Scottish patients receiving methadone in primary care: retrospective cohort study.

OBJECTIVE: To assess predictors of mortality in a population of people prescribed methadone. DESIGN: Retrospective cohort study. SETTING: Geographically defined population in Tayside, Scotland. PARTICIPANTS: 2378 people prescribed and dispensed liquid methadone between January 1993 and February 2004. MAIN OUTCOME MEASURES: All cause mortality (primary outcome) and drug dependent cause specific mortality (secondary outcome) by means of Cox proportional hazards models during 12 years of follow-up. RESULTS: Overall, 181 (8%) people died. Overuse of methadone (adjusted hazard ratio 1.67, 95% confidence interval 1.05 to 2.67), history of psychiatric admission (2.47, 1.67 to 3.66), and increasing comorbidity measured as Charlson index >or=3 (1.20, 1.15 to 1.26) were all associated with an increase in all cause mortality. Longer duration of use (adjusted hazard ratio 0.95, 0.94 to 0.96), history of having urine tested (0.33, 0.22 to 0.49), and increasing time since last filled prescription were protective in relation to all cause mortality. Drug dependence was identified as the principal cause of death in 60 (33%) people. History of psychiatric admission was significantly associated with drug dependent death (adjusted hazard ratio 2.41, 1.25 to 4.64), as was history of prescription of benzodiazepines (4.35, 1.32 to 14.30). CONCLUSIONS: Important elements of care in provision of methadone maintenance treatment are likely to influence, or be a marker for, a person's risk of death.

Opioid deaths in rural Virginia: a description of the high prevalence of accidental fatalities involving prescribed medications.

In rural Virginia, drug overdose deaths increased 300% from 1997 to 2003. Polydrug deaths predominate (57.9%) in this review of 893 medical examiner cases. Prescription opioids (74.0%), antidepressants (49.0%), and benzodiazepines (39.3%) were more prevalent than illicit drugs. Two-thirds of decedents were 35-54 years old; 37% were female. When compared to western Virginia metropolitan cases, polydrug abuse was more common, specific medication combinations were found, the death rate per population was higher, and fewer illicit drugs were detected. These rural prescription overdose deaths differ from urban illicit drug deaths, suggesting the need for different strategies in prevention, treatment, and intervention by clinicians and policymakers.
