RESUMO

INTRODUCTION: Patients who make 5 or more visits per year to hospital emergency departments (EDs) are usually considered ED frequent users (FUs). This study aims to better characterize the influence of alcohol and other drug use-related disorders in this phenomenon in a European Mediterranean country with public, universal, tax-financed healthcare system. METHODS: Matched case-control study. Cases were adults between 18 and 65 years old who consulted 5 or more times the ED of a tertiary hospital in Spain between December 2018 and November 2019. Each case was assigned a control of the same age and gender, who appeared to the ED on the same day, but who made 4 visits or less to the service during the study period. The electronic record of the first ED visit during this period was used to extract the variables of interest: emergency care received, clinical and social characteristics. Predictors of frequent ED use were identified with conditional logistic regression. RESULTS: 609 case-control pairs (total n = 1,218) were selected. History of alcohol-related conditions (adjusted odds ratio [AOR] = 1.82 [95% CI: 1.26-2.64] p = 0.001) and also other drug use-related disorders (AOR = 1.50 [95% CI: 1.11-2.03] p = 0.009) significantly increased the probability of frequent use of emergency services. DISCUSSION/CONCLUSION: Alcohol-related conditions and other drug use-related disorders must be evaluated in all ED FUs. Specific action protocols to concurrently address repeated attendance and addictions in the emergency room could be a good tool to reduce frequent ED use.

RESUMO

Introduction: There is an extreme shortage of addiction psychiatrists and a lack of representation of addiction psychiatry (ADP) fellows from racial/ethnic minoritized backgrounds. ADP fellowship websites are integral in engaging potential applicants. It is therefore critical to understand the quality of engagement that trainees are having with ADP fellowship websites. The aim of this study was to investigate the accessibility and content of ADP fellowship program websites in the U.S. Methods: A list of ADP Fellowship programs was obtained from the Accreditation Council for Graduate Medical Education. A critical textual analysis of 42 unique factors within four categories (accessibility, recruitment, education, and health equity) was performed for each ADP fellowship website. Results: Of 51 ADP fellowships, 47 (92.2%) had websites. Information about social media accounts was largely missing from ADP fellowship websites. For recruitment, program description (95.7%) and program director name (76.6%) were most readily available, while interview day (0.00%) and vacation details (10.6%) were least available. For education, a list of rotations (55.3%) and didactics/lectures (40.4%) were most readily available, while post fellowship placement (6.4%), call schedule (4.3%), and responsibility progression (2.1%) were least available. The most prevalent health equity factors were gender-inclusive language (100%) and an absence of stigmatizing addiction language (100%). The least listed were statements of commitment to health equity (0.0%), antiracism training (2.1%), and harm-reduction strategies (4.3%). Conclusions: There are considerable gaps in the amount and types of information provided by ADP fellowship websites. Many existing websites are poorly interfacing with potential leaders in the field. The development of ADP fellowship websites could serve as a low-cost recruitment tool to engage potential addiction specialists. Our findings underscore the need for ADP fellowships to optimize their websites to engage bourgeoning leaders in addiction and optimize access to more comprehensive information.

RESUMO

Background: There is an alarming shortage of addiction psychiatrists in the United States. To promote interest in addiction psychiatry (ADP), it is essential to maximize resources available through ADP fellowship websites. The aim of this study was to investigate the perceived adequacy and accessibility of content on ADP fellowship websites and discover what further information is considered important among trainees interested in becoming addiction specialists. Methods: Three virtual focus groups were conducted between January and February 2021 among medical students and residents in diverse geographic regions. Participants were asked about the availability of information on ADP fellowship program websites and other material they would like to see available. Focus groups were recorded, with data transcribed and coded using NVivo 11 and Dedoose. A coding scheme was deductively developed based on the core research questions. Results: The majority of participants (N = 27) identified areas of dissatisfaction with the content currently available on ADP websites. The sample was highly representative of racial and ethnic minoritized trainees (n = 12) and genderqueer/non-binary participants (n = 3). Three major themes were identified and durable across all focus groups: lack of emphasis on diversity/health equity, lack of portrayal of everyday life and activities of fellows, and inadequate representation of curricula. Overwhelmingly, participants identified a dedication to health equity (for example, working with minoritized populations) as a key deciding factor in whether to apply to a particular ADP fellowship. Conclusions: ADP fellowship websites are perceived to have considerable variability in the amount and quality of information. Many do not appear to provide the full spectrum of content desired by diverse potential applicants, such as information regarding current fellows and community-centered initiatives. This is concerning, as it suggests ADP fellowships may be interfacing poorly with burgeoning leaders, especially those from race and gender minoritized backgrounds, neglecting potential opportunities to develop future addiction specialists.

RESUMO

OBJECTIVE: This article describes the evolution of subspecialty training and certification in addiction psychiatry. The impact of the newer subspecialty in addiction medicine is also addressed. METHODS: Information about programs and trainees was obtained from records of the Accreditation Council for Graduate Medical Education. Information about addiction psychiatry certification was obtained from the records of the American Board of Psychiatry and Neurology (ABPN). Information about the addiction medicine subspecialty was obtained from the American Board of Preventive Medicine. RESULTS: In AY 2020-2021, there were 53 addiction psychiatry programs with 92 fellows, and the numbers of each have increased over the past 5 academic years. The total number of addiction psychiatry certificates awarded through 2020 was 2806. Three years after addiction medicine programs were first accredited, there were 83 programs with 149 fellows. Thus far, 3282 addiction medicine certificates have been awarded, 1275 (38.8%) of them to ABPN diplomates. CONCLUSIONS: In the 30 years since addiction psychiatry received subspecialty recognition, the numbers of training programs and fellows have grown steadily and are continuing to increase. Recently, the numbers of training programs and fellows in the newer subspecialty of addiction medicine have grown rapidly with substantial psychiatry involvement in addiction medicine training and certification programs. Nonetheless, it is apparent that the need for specialists with expertise in substance use disorders will far exceed the supply for the foreseeable future.

RESUMO

BACKGROUND: A role for addiction psychiatry in aesthetic treatment-seeking behavior has been evidenced for ultraviolet light tanning. OBJECTIVE: We aim to demonstrate an initial proof of concept for the presence of addictive behaviors in cosmetic procedure use. METHODS: Adults visiting a cosmetic dermatology practice with history of at least 1 cosmetic procedure and consideration of at least 1 cosmetic procedure in the past 12 months were included. Two previously validated instruments in the detection of alcohol use disorder, the Cut Down, Annoyed, Guilty, Eye-Opener (CAGE) questionnaire, and Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-V) criteria were modified to evaluate participants for a substance-related disorder (SRD) in cosmetic procedures. RESULTS: Of 153 adults, 34 (22.2%) met modified CAGE criteria, and 40 (26.1%) met modified DSM-V criteria. Results from both instruments were significantly associated (P < .0002). Significant differences in consideration and use of cosmetic treatments were found in SRD positive versus negative groups (P < .0001 and P = .009, respectively). LIMITATIONS: Preliminary criteria for SRD in cosmetic procedure use in this study has not yet been validated. CONCLUSIONS: A type of SRD involving cosmetic procedures may exist, and qualifying individuals may have increased cosmetic treatment use. Future efforts to rigorously validate an instrument for SRD detection in cosmetic procedures use are warranted for future research and clinical application.

RESUMO

Substance use disorders (SUDs) are major causes of morbidity and mortality in the United States. SUDs commonly co-occur with other psychiatric and physical illness and often require management by an addiction specialist to comprehensively address patients' complex needs. The American Board of Medical Specialties (ABMS) offers two pathways leading to addiction subspecialty board certification: addiction psychiatry (American Board of Psychiatry and Neurology) and addiction medicine (American Board of Preventive Medicine). We explore the history of the distinct but overlapping practices of addiction medicine and addiction psychiatry and describe the unique contributions of each field. Specifically, we review skill sets, specialty training, and career outcomes for physicians specializing in the assessment and management of SUDs. We conclude by highlighting collaboration between the two specialties and offer a shared vision for the future of addiction specialty care.

RESUMO

OBJECTIVE: Substance use disorder (SUD) is a global concern. Evidence from high-income countries suggests that SUD training for psychiatry residents is less than optimal but it is unknown whether the situation is different in low-/middle-income settings. This study assessed psychiatry residents' perception of their SUD training. METHODS: A cross-sectional survey was conducted among general psychiatry residents in Nigeria from November 2018 to May 2019. Data were collected through self-completion of an English-language questionnaire with multiple-choice and open-ended questions administered face-to-face and online. RESULTS: A total of 51 participants completed the questionnaire, mean age 33.6 years and 76.5% men. Most participants (70.6%) expressed interest in addiction psychiatry, and 47.1% perceived their SUD training as inadequate. When asked to rate satisfaction with the SUD training they have received so far, 52.9% were unsatisfied, and the absence of in-house SUD training (29.4%) was the leading cause of dissatisfaction. For those who were satisfied, the most common reasons were availability of SUD training and treatment-related factors (31.4%). The most frequent suggestions for making addiction psychiatry subspecialty attractive to psychiatry residents were provision of SUD treatment units, structured SUD training, and continuity of such training. Equipping existing SUD treatment units and creating more treatment units were the most common suggestions for improving current SUD training. CONCLUSION: This study demonstrated a high level of interest in addiction psychiatry, but satisfaction with SUD training was mixed. Addressing causes of dissatisfaction and areas suggested for improvement would be necessary to sustain interest.

RESUMO

This paper aimed to summarize kratom's psychological effects on users and the Islamic views on kratom use. A literature survey of published kratom studies, teachings based on the holy Qur'an, the Sunnah, and views of several Islamic scholars based on qualitative methodology through text analysis was conducted. The results demonstrated that despite its beneficial therapeutic effects, the harm induced by kratom outweighs its benefits. We concluded that kratom use for medicinal purposes is only warranted if useful constituent mitragynine can be extracted and used on its own, and if more rigorous human studies demonstrated good safety profile and efficacy of mitragynine for therapeutic purposes.

RESUMO

The increasingly widespread legalization of recreational marijuana should raise concerns regarding the societal and medical impact of its use. The relative cultural acceptance for its use should be counterbalanced with an honest and scientific review of the adverse impacts. This article provides a synopsis of recent studies that point to significant concerns from medical and psychiatric viewpoints. SUMMARY: With the increasing number of states that have legalized the use of recreational marijuana, concerns regarding its negative effects are necessary. There is growing scientific evidence that the use of marijuana for recreational purposes has a wide variety of negative health effects, both physical and psychiatric.

RESUMO

Introduction: Well-structured instructions for authors in journals help researchers in reporting unbiased results, which subsequently facilitates the review process. There have been reports of systematic evaluations of instructions for authors from journals in various medical specialties. However, precise information on the nature and extent of these instructions for authors in addiction science is lacking. Hence, this study systematically evaluated the instructions for authors for journals in addiction science. Methods: A total of 1139 journal titles were retrieved across multiple databases. Finally, 88 exclusive titles fulfilling the eligibility criteria were considered in this study. The four domains evaluated were journal characteristics, reporting, statistical reporting, and ethical requirements. Results: More than half of the journals were published by academic institutions or professional societies. Less than one-fourth of the journals endorsed adherence to various reporting guidelines and endorsed the Consolidated Statements on Randomized Controlled Trials guidelines to the maximum level (14.8%). Approximately, half (48.9%) of the journals had a separate section on "statistical analysis." The various parameters of statistical reporting were suboptimally endorsed. Conclusion/Importance: The instructions for authors in addiction science journals provide insufficient information in various domains. There is an urgent need to improve the author instructions segment of addiction science journals so that the process of research dissemination can occur more effectively. A higher rate of endorsement of various reporting guidelines and statistical reporting may help to minimize reporting bias as well as prevent unnecessary delays in the publication of important research findings.

RESUMO

AIM: The objective of this study was to examine the relationship between Internet Addiction (IA), Attention Deficit Hyperactivity Disorder (ADHD) symptoms and online activities in an adult population. METHODS: A sample of 400 individuals aged 18 to 70 completed the Adult ADHD Self-Report Scale (ASRS), Young's Internet Addiction Test, and their preferred online activities. RESULTS: A moderate association was found between higher levels of ADHD symptoms and IA. The best predictors of IA scores were ADHD symptoms, age, playing online games and spending more time online. CONCLUSION: Our findings further support a positive relationship between ADHD symptoms and excessive internet use.

RESUMO

OBJECTIVE: Assessment is pivotal to the work of health care professionals and social workers, as it provides fundamental, systematic information that is essential when planning interventions. Many patients have addiction problems as well as psychiatric illness and they very often interact. An assessment tool addressing both areas would be beneficial for this large group of patients. This pilot study explores feasibility and adequacy of the Danish translation of the Measurements in Addiction for Triage and Evaluation (MATE) assessment in the following sectors: drug and alcohol treatment, psychiatry, and social service. METHODS: Thirty staff members from psychiatric hospital, social services, and treatment institutions for alcohol and substance abuse were recruited. Staff that had direct contact with clients were planned to perform at least two MATE interviews. RESULTS: Nineteen interviews were completed. Information gathered from MATE was reported to be adequate for making a triage decision, but psychiatric staff reported that MATE gathered too much irrelevant information, especially concerning daily life functioning. Overall feasibility was satisfactory, but staff and patients were at some points critical of wording, casting doubt on the understanding of some questions. CONCLUSIONS: This pilot study found that MATE gathers relevant and sufficient information in an appropriate amount of time.

RESUMO

OBJECTIVE: A majority of physicians feel poorly trained in the treatment of chronic pain and addiction. As such, it is critical that medical students receive appropriate education in both pain management and addiction. The purpose of this study was to assess the pre-clinical curriculum in pain medicine and addiction from the perspective of students after they had completed their pre-clinical training and to assess what they perceived as the strengths and weaknesses of their training. METHODS: The authors conducted focused interviews among clinical medical students who had completed at least 6 months of clerkships. The interviews targeted the students' retrospective opinions about the pre-clinical curriculum and their preparedness for clinical encounters with either pain or addiction-related issues during their rotations. Coders thematically analyzed the de-identified interview transcripts, with consensus reached through discussion and code modification. RESULTS: Themes that emerged through the focused interviews included: fragmented curricular structure (and insufficient time) for pain and addiction medicine, not enough specific treatment strategies for pain or addiction, especially for complex clinical scenarios, and lack of a trained work-force to provide guidance in the management of pain and addiction. CONCLUSION: This study demonstrated the feasibility of gathering student perspectives to inform changes to improve the pre-clinical curriculum in pain and addiction medicine. Students identified multiple areas for improvement at the pre-clerkship level, which have informed updates to the curriculum. More research is needed to determine if curricular changes based on student feedback lead to improved learning outcomes.

RESUMO

This commentary highlights the growing demand for substance abuse prevention and treatment, summarizes the literature regarding the current insufficiencies in substance abuse training in medical schools, and suggests strategies to address this gap in physician education. The authors describe how the combination of mandated coverage for substance abuse services and expanding treatment needs means that more physicians, regardless of their patient populations, will be faced with addressing the problem of substance use. The authors review the literature on substance abuse training in medical schools, which indicates insufficient exposure to this topic. The authors describe how current substance abuse training at medical schools is focused on transmitting scientific knowledge with relatively little education or training in attitudes and skills central to effective prevention and treatment. Given the gap between clinical need and physician education, the authors suggest several strategies for medical schools to increase training in substance abuse knowledge, attitudes, and skills, which will enhance the practice of evidence-based care. The authors posit that medical curricular reform, combined with initiatives to change clinical culture around substance abuse, will translate into improved rates of screening, shorter overall length of treatment, effective referrals for continued treatment, and increased access to care for individuals who use substances and so reduce the morbidity and mortality associated with substance use.

RESUMO

Objective An innovative course was developed for fellows enrolled in the Yale School of Medicine Addiction Psychiatry program to educate them in key principles of adult learning, apply these principles in a case conference presentation, and to improve skills in providing and receiving feedback. Methods An initial training module on educational skills was followed by individual mentorship to prepare a case presentation. A feedback module provided space to learn and practice skills in feedback delivery. Results The program showed positive results and improved confidence levels of the participants in presenting and providing/receiving feedback. Conclusions Implementing a course designed to improve teaching and feedback skills is feasible in a 1-year Addiction Psychiatry fellowship.

RESUMO

This perspective article focuses on the need for training and education for undergraduate medical students on substance-related disorders, and describes initiatives undertaken in the United Kingdom (UK), Netherlands, United States (US), and Norway to develop the skills, knowledge, and attitudes needed by future doctors to treat patients adequately. In addition, we stress that in postgraduate training, further steps should be taken to develop Addiction Medicine as a specialized and transverse medical domain. Alcohol use disorder is a growing public health problem in the geriatric population, and one that is likely to continue to increase as the baby boomer generation ages. Prescription drug misuse is a major concern, and nicotine misuse remains problematic in a substantial minority. Thus, Addiction Medicine training should address the problems for this specific population. In recent years, several countries have started an Addiction Medicine specialty. Although addiction psychiatry has been a subspecialty in the UK and US for more than 20 years, in most countries it has been a more recent development. Additional courses on addiction should be integrated into the curriculum at both undergraduate and postgraduate levels, as well as form part of the continuous training of other medical specialists. It is recommended that further research and mapping of what is currently taught in medical programs be undertaken, so as to enhance medical education in addiction and improve treatment services.

RESUMO

AIM: Prescription drug abuse, including benzodiazepines, is a growing health problem in Japan. This study examined the community pharmacist's clinical behavior regarding patients who overdose on prescribed drugs, and explored the possibility of overdose prevention by community pharmacists. METHODS: We surveyed all registered community pharmacies with dispensing functions (n = 1867) in the Saitama Pharmaceutical Association. An anonymous self-administered questionnaire was mailed to each pharmacy. Respondents were asked about clinical behavior such as medication counseling and referral to the prescriber if prescription drug overdose was identified. RESULTS: Among respondents, 26% of community pharmacists reported clinical experience of working with patients who overdosed on prescribed drugs in the previous year. Half of respondents evaluated their practice such as medication counseling and referral to the prescriber as 'good'. On multivariate analysis, a 'poor' self-evaluation of referral to the prescriber was significantly associated with the following perceptions: 'insufficient confidence in communication with prescribers' (odds ratio [OR], 2.7; 95% confidence interval [95%CI]: 1.4-5.3), and 'to avoid trouble with prescribers' (OR, 1.7; 95%CI: 1.0-2.7). CONCLUSION: Japanese community pharmacists could prevent prescription drug abuse in their practice, but the pharmacists who have insufficient confidence in communication with prescribers and who are afraid of trouble with a prescriber, reported poor self-evaluation for referral to the prescribers. All prescribers should understand the importance of referral by community pharmacists, to assist community pharmacists in playing a critical role in prevention of prescription drug abuse.

RESUMO

OBJECTIVE: The authors investigated cortico-striatal reactivity to drug cues (as compared with neutral and food cues), drug cue reappraisal, food cue savoring, and their correlations with heroin craving in individuals with heroin use disorder compared with healthy control subjects. METHODS: Cross-sectional changes in functional MRI blood-oxygen-level-dependent signal during a novel cue reactivity task were assessed in 32 individuals with heroin use disorder (mean age, 40.3 years; seven women) and 21 age- and sex-matched healthy control subjects (mean age, 40.6 years; eight women). RESULTS: Drug cue reactivity (vs. neutral cues) was significantly higher in the nucleus accumbens in the heroin use disorder group compared with the control group and nominally significantly higher in the orbitofrontal cortex (OFC); ventromedial prefrontal cortex (vmPFC) activity positively correlated with drug craving. Drug cue reactivity (vs. salient food cues) was also higher in the inferior frontal gyrus (IFG) in the heroin use disorder group compared with the control group. Drug reappraisal and food savoring (vs. passive viewing) showed increased IFG and supplementary motor area activity in all participants; in the heroin use disorder group, higher IFG/dorsolateral PFC (dlPFC) activity during drug reappraisal and rostral anterior cingulate cortex (ACC) activity during food savoring were associated with lower drug cue-induced craving and longer treatment, respectively. A direct comparison of regulation of reactivity to both salient cues revealed widespread group differences such that drug reappraisal activity was higher in the heroin use disorder group and food savoring activity was higher in the control group in both cortical (e.g., OFC, IFG, ACC, vmPFC, and insula) and subcortical (e.g., dorsal striatum and hippocampus) regions. Higher drug reappraisal versus food savoring in the dlPFC was associated with higher self-reported methadone dosage in the heroin use disorder group. CONCLUSIONS: The results demonstrate cortico-striatal upregulation during drug cue exposure and impaired reactivity during processing of alternative non-drug rewards in the heroin use disorder group. Normalizing cortico-striatal function by reducing drug cue reactivity and enhancing natural reward valuation may inform therapeutic mechanisms for reducing drug craving and seeking in heroin addiction.
