Assessing substance abuse treatment need: a statewide hospital emergency department study

Acute care utilization and its associated determinants among patients with substance-related disorders: A worldwide systematic review and meta-analysis

INTRODUCTION

Identifying determinants of emergency department (ED) use and hospitalization among patients with substance-related disorders (SRDs) can improve health services to address unmet health needs.

AIM

The present study aimed to identify the prevalence rates of ED use and hospitalization, and their associated determinants among patients with SRDs.

METHODS

Studies in English published from January 1, 1995, to December 1, 2022, were searched on PubMed, Scopus, Cochrane Library, and Web of Science to identify primary studies.

RESULTS

The pooled prevalence rates of ED use and hospitalization among patients with SRDs were 36% and 41%, respectively. Patients with SRDs who were the most at risk of being both ED users and hospitalized were those (i) having medical insurance, (ii) having other drug and alcohol use disorders, (iii) having mental health disorders, and (iv) having chronic physical illnesses. A lower level of education increased the risk of ED use only.

DISCUSSION

To decrease ED use and hospitalization, more comprehensive services may be offered to these vulnerable patients with diversified needs.

IMPLICATIONS FOR PRACTICE

Chronic care integrating outreach interventions could be more provided for patients with SRDs after discharge from acute care units or hospitals.

Universal screening for substance use by Peer Support Specialists in the Emergency Department is a pathway to buprenorphine treatment

INTRODUCTION

Evidence suggests emergency department (ED)-initiated buprenorphine as efficacious in connecting ED patients to Medications for Opioid Use Disorder (MOUD) utilizing peer support specialists (PSS). However, there are no reports of implementation of ED-initiated buprenorphine in practice. Such information is crucial to support the adoption of ED-initiated buprenorphine.

METHODS

In this quality improvement pilot study, a PSS screened ED patients over age 18 with the Tobacco, Alcohol, Prescription medication, and other Substance use - 1 (TAPS-1). The PSS considered the patient a positive screen if the patient met the following criteria: risky weekly alcohol use, illicit drugs, or prescription drugs. For patients who screened positive, the PSS delivered a brief intervention and assessed interest in treatment. An ED clinician assessed patients who screened positive for heroin/opioid use and were interested in treatment for buprenorphine induction.

RESULTS

From January through June 2019, 1037 patients were screened for risky substance use, and, of these, 238 (23%) screened positive. The distribution of primary substance used was: 51% alcohol, 26% cannabis, 7.5% cocaine, 7.5% heroin, and 3.3% prescription opioids. Of the 23 patients who screened positive for heroin/opioid use and requested treatment, seven were admitted to the hospital. Of the remaining 16 patients, 14 patients wanted buprenorphine treatment, seven were provided buprenorphine in the ED, and four of these attended their intake appointments for community-based MOUD treatment.

CONCLUSION

ED-initiated buprenorphine facilitated by a PSS is feasible and requires coordination and planning. Approaches to ED-initiated buprenorphine that screen only for opioid use will miss many patients interested in substance use treatment.

Amphetamine-type stimulant use among patients admitted to the emergency department behavioural assessment unit: Screening and referral outcomes

Amphetamine-type stimulant use, including methamphetamine, amphetamine, and 3,4-methylenedioxymethamphetamine, is associated with a range of behavioural symptoms. Screening for amphetamine-type stimulant use among people presenting to the emergency department with behavioural disturbance and referral to treatment has not been evaluated. The objective of this study was to determine the prevalence of amphetamine-type stimulant use among patients admitted to a behavioural assessment unit and report referral outcomes. A prospective observational design was used. Individuals who tested positive or self-reported amphetamine-type stimulant use were referred to the alcohol and other drug clinician. We measured the prevalence of amphetamine-type stimulant use in saliva and by self-report along with rates of referral. The setting was a behavioural assessment unit located within an Australian emergency department. Admitted adults were enrolled from July to December 2017. Those who tested positive or self-reported amphetamine-type stimulant use were provided with harm reduction advice and offered referral. Four hundred and seventy-two tests were performed. Fifteen were excluded due to invalid results or redundant enrolment. Of the 457 individuals, 59% were male, with a mean age of 35 years (SD 13). Fifty-three (11.6%, 95% CI: 8.9-15.0) tested positive for amphetamine-type stimulants. Of those with a negative test, 44 (9.6%, 95% CI: 7.3-12.7) self-reported amphetamine-type stimulant use in the previous 24 hours. The prevalence of amphetamine-type stimulant use was 21.2% (95% CI: 17.7-25.2). Most accepted referral to the alcohol and other drug clinician (85.6%, 95% CI 77.2-91.2). The emergency visit represents a window of opportunity for screening for amphetamine-type stimulant use and initiating referrals.

Emergency Department Screening for Unhealthy Alcohol and Drug Use with a Brief Tablet-Based Questionnaire

Background

Screening for unhealthy alcohol and drug use in the emergency department (ED) can be challenging due to crowding, lack of privacy, and overburdened staff. The objectives of this study were to determine the feasibility and utility of a brief tablet-based screening method in the ED and if patients would consider a face-to-face meeting with a certified alcohol and drug counselor (CADC) for more in-depth screening, brief intervention, and referral to treatment (SBIRT) helpful via this interface.

Methods

A tablet-based questionnaire was offered to 500 patients. Inclusion criteria were age ≥18, Emergency Severity Index 2–5, and English comprehension. Subjects were excluded if they had evidence of acute intoxication and/or received sedating medication.

Results

A total of 283 (57%) subjects were enrolled over a 4-week period, which represented an increase of 183% over the monthly average of patients referred for SBIRT by the CADC prior to the study. There were 131 (46%) who screened positive for unhealthy alcohol and drug use, with 51 (39%) and 37 (28%) who screened positive for solely unhealthy alcohol use and drug use/drug use disorders, respectively. There were 43 (33%) who screened positive for combined unhealthy alcohol and drug use. Despite willingness to participate in the tablet-based questionnaire, only 20 (15%) with a positive screen indicated via the tablet that a face-to-face meeting with the CADC for further SBIRT would be helpful.

Conclusion

Brief tablet-based screening for unhealthy alcohol and drug use in the ED was an effective method to increase the number of adult patients identified than solely by their treating clinicians. However, only a minority of subjects screening positive using this interface believed a face-to-face meeting with the CADC for further SBIRT would be helpful.

Variables associated with low, moderate and high emergency department use among patients with substance-related disorders

AIMS

This study identified factors associated with frequency of emergency department (ED) use for medical reasons among patients with substance-related disorders (SRD) in Quebec (Canada) for 2014-15.

METHODS

Participants (n = 4731) were categorized as: 1) low (1 visit/year), 2) moderate (2 visits/year), and 3) high (3+ visits/year) ED users. Independent variables included predisposing, enabling and needs factors based on the Andersen Behavioral Model. Multinomial logistic regression identified associated variables.

RESULTS

Factors positively associated with moderate and high ED use included adjustment disorders, suicidal behavior, alcohol-induced disorders, less urgent to non-urgent illness acuity, referral to local health community services centers (LHCSC) at discharge, and living in a materially deprived area. Factors positively associated with high ED use only included anxiety disorders, alcohol use disorders, drug use disorders, chronic physical illness, subacute problems, prior ED use for MD and/or SRD, prior LHCSC medical interventions, physician consultation within one month after discharge, living in very deprived or middle-class areas, and, negatively, being hospitalized for medical reasons in second ED visit. Moderate ED use only was negatively associated with alcohol intoxication and being referred to a GP at ED discharge.

CONCLUSIONS

Compared to low ED users, most high users with SRD were men presenting more complex and severe conditions. They visited ED mainly for subacute or non-urgent problems. Compared to low ED users, most moderate users had alcohol-induced disorders, less alcohol intoxication, and acute common MD. They visited ED mainly for non-urgent care. Diverse strategies should be implemented to reduce ED visits, targeting each group.

Test characteristics of a drug CAGE questionnaire for the detection of non-alcohol substance use disorders in trauma inpatients

BACKGROUND

Non-alcohol substance use disorders (drug use disorders [DUDs]) are common in trauma patients.

OBJECTIVE

To determine the test characteristics of a 4-item drug CAGE questionnaire to detect DUDs in a cohort of adult trauma inpatients.

METHODS

Observational cross-sectional cohort of 1,115 adult patients admitted directly to a level-one trauma center between September, 1994 and November, 1996. All participants underwent both a 4-item drug CAGE questionnaire and the substance use disorder section of a structured psychiatric diagnostic clinical interview (SCID) (DSM-IIIR criteria), administered by staff unaware of their clinical status. Sensitivity, specificity, positive (PPV) and negative predictive values (NPV), positive (LR+) and negative likelihood ratios (LR-), and the area under the receiver operating curve (AUC) were calculated for each individual question and the overall questionnaire, using SCID-generated DUD diagnoses as the standard. Performance characteristics of the screen were also compared across selected sociodemographic, injury mechanism, and diagnostic sub-groups.

RESULTS

Subjects with DUDs were common (n = 349, 31.3%), including cannabis (n = 203, 18.2%), cocaine (n = 199, 17.8%), and opioids (n = 156, 14.0%). The screen performed well overall (AUC = 0.90, 95% CI: 0.88-0.91) and across subgroups based on age, sex, race, marriage status, income, education, employment status, mechanism of injury, and current/past DUD status (AUCs 0.75-1.00). Answering any one question in the affirmative had a sensitivity = 83.4% (95% CI: 79.1-87.1), specificity = 92.3% (95% CI: 90.2-94.1), PPV = 83.1%, LR+ = 10.8.

CONCLUSIONS

The 4-item drug CAGE and its individual questions had good-to-excellent ability to detect DUDs in this adult trauma inpatient population, suggesting its usefulness as a screening tool.

Availability of Outpatient Addiction Treatment and Use of Emergency Department Services Among Medicaid Enrollees

OBJECTIVE

The study examined whether the number of outpatient addiction programs accepting Medicaid in South Carolina counties is linked to repeat use of the emergency department for addiction-related conditions.

METHODS

The study included the population all adult Medicaid enrollees (N=2,401) in South Carolina with at least one addiction-related emergency service visit in 2012 or 2013. A random-effects logistic regression model was used to examine the association between outpatient addiction treatment availability and repeat use by Medicaid enrollees of emergency services for addiction-related conditions.

RESULTS

Enrollees in counties with two or more programs that accept Medicaid were less likely to have a repeat addiction-related emergency service visit than enrollees in counties with only one program that accepts Medicaid.

CONCLUSIONS

Availability of outpatient addiction treatment may reduce the need for addiction-related emergency services. Research is needed to explore potential causal mechanisms underlying this observed relationship.

Urine Drug Screen Trends from 1998 through 2011 Among Emergency Department Patients Treated in a University Teaching Hospital

The emergency department (ED) at Louisiana State University-Health Science Center in Shreveport (LSUHSC-S) serves an urban population with a large rural catchment area. This study focuses on demographic variables in substance abuse trends in this region based on urine drug screen (UDS) results. A database of de-identified UDSs ordered in the ED at LSUHSC-S between 1998 and 2011 was analyzed. Samples were tested for the presence of amphetamines, barbiturates, benzodiazepines, cannabinoids, cocaine, 3,4-methylenedioxymethamphetamine (MDMA), methadone, methamphetamine, opiates, phencyclidine, and propoxyphene. The patient population was categorized by age group, gender, and race. The majority of tests were performed on African-American and Caucasian patients ages 18 to 54 followed by the 0 to 11-year-old group. Of the drugs tested, cannabinoids represented the highest percentage of positive results in both the African-American and Caucasian populations. Opiates returned the highest percent of positive results among all prescription drugs. The Caucasian population predominated in positive tests for prescription drugs (opiates and benzodiazepines), while the African-American population predominated in results positive for illicit drugs (cannabinoids and cocaine). The increasing presence of opiates and cannabinoids, particularly in very young patients, should prompt policy makers and healthcare providers to develop intervention strategies to protect the most vulnerable populations.

Impact of a brief intervention on reducing alcohol use and increasing alcohol treatment services utilization among alcohol- and drug-using adult emergency department patients

Most previous brief intervention (BI) studies have focused on alcohol or drug use, instead of both substances. Our primary aim was to determine if an alcohol- and drug-use BI reduced alcohol use and increased alcohol treatment services utilization among adult emergency department (ED) patients who drink alcohol and require an intervention for their drug use. Our secondary aims were to assess when the greatest relative reductions in alcohol use occurred, and which patients (stratified by need for an alcohol use intervention) reduced their alcohol use the most. In this secondary analysis, we studied a sub-sample of participants from the Brief Intervention for Drug Misuse in the Emergency Department (BIDMED) randomized, controlled trial of a BI vs. no BI, whose responses to the Alcohol, Smoking and Substance Involvement Screening Test (ASSIST) indicated a need for a BI for any drug use, and who also reported alcohol use. Participants were stratified by their ASSIST alcohol subscore: 1) no BI needed, 2) a BI needed, or 3) an intensive intervention needed for alcohol use. Alcohol use and alcohol treatment services utilization were measured every 3 months for 12 months post-enrollment. Of these 833 participants, median age was 29 years-old, 46% were female; 55% were white/non-Hispanic, 27% black/non-Hispanic, and 15% Hispanic. Although any alcohol use, alcohol use frequency, days of alcohol use, typical drinks consumed/day, and most drinks consumed/day decreased in both the BI and no BI arms, there were no differences between study arms. Few patients sought alcohol use treatment services in follow-up, and utilization also did not differ by study arm. Compared to baseline, alcohol use reduced the most during the first 3 months after enrollment, yet reduced little afterward. Participants whose ASSIST alcohol subscores indicated a need for an intensive intervention generally had the greatest relative decreases in alcohol use. These results indicate that the BI was not efficacious in reducing alcohol use among alcohol- and drug-using adult ED patients than the self-assessments alone, but suggest that self-assessments with or without a BI may confer reductions in alcohol use.

Should alcohol screening be a routine practice in alcohol-related facial trauma care? A narrative review

The link between alcohol intoxication and Emergency Department (ED) attendance for management of alcohol-related injuries has been well documented. The acute settings such as ED and surgical wards may not be the most appropriate environment for treatment of chronic conditions, but traumatic episode presentation to ED may offer the most opportunistic time to focus on screening against harmful alcohol use in order to provide timely feedback and support. Although ED provides an opportunity to identify patients with alcohol problems, the initial challenge is finding suitable ways to identify and screen affected patients. This paper is a narrative review on methods of alcohol screening and its effectiveness and efficacy in trauma care setting. It is second part in a series on implementation of screening and brief intervention in managing trauma patients.

Trends and Correlates of Cannabis-involved Emergency Department Visits: 2004 to 2011

OBJECTIVES

To examine trends and correlates of cannabis-involved emergency department (ED) visits in the United States from 2004 to 2011.

METHODS

Data were obtained from the 2004 to 2011 Drug Abuse Warning Network. We analyzed trend in cannabis-involved ED visits for persons aged ≥12 years and stratified by type of cannabis involvement (cannabis-only, cannabis-polydrug). We used logistic regressions to determine correlates of cannabis-involved hospitalization versus cannabis-involved ED visits only.

RESULTS

Between 2004 and 2011, the ED visit rate increased from 51 to 73 visits per 100,000 population aged ≥12 years for cannabis-only use (P value for trend = 0.004) and from 63 to 100 for cannabis-polydrug use (P value for trend < 0.001). Adolescents aged 12-17 years showed the largest increase in the cannabis-only-involved ED visit rate (rate difference = 80 per 100,000 adolescents). Across racial/ethnic groups, the most prevalent ED visits were noted among non-Hispanic blacks. Among cannabis-involved visits, the odds of hospitalization (vs ED visits only) increased with age strata compared with age 12 to 17 years.

CONCLUSIONS

These findings suggest a notable increase in the ED visit numbers and rates for both the use of cannabis-only and cannabis-polydrug during the studied period, particularly among young people and non-Hispanic blacks.

Health Evaluation and Referral Assistant: A Randomized Controlled Trial of a Web-Based Screening, Brief Intervention, and Referral to Treatment System to Reduce Risky Alcohol Use Among Emergency Department Patients

Background

Computer technologies hold promise for implementing alcohol screening, brief intervention, and referral to treatment (SBIRT). Questions concerning the most effective and appropriate SBIRT model remain.

Objective

The aim of this study was to evaluate the impact of a computerized SBIRT system called the Health Evaluation and Referral Assistant (HERA) on risky alcohol use treatment initiation.

Methods

Alcohol users (N=319) presenting to an emergency department (ED) were considered for enrollment. Those enrolled (n=212) were randomly assigned to the HERA, to complete a patient-administered assessment using a tablet computer, or a minimal-treatment control, and were followed for 3 months. Analyses compared alcohol treatment provider contact, treatment initiation, treatment completion, and alcohol use across condition using univariate comparisons, generalized estimating equations (GEEs), and post hoc chi-square analyses.

Results

HERA participants (n=212; control=115; intervention=97) did not differ between conditions on initial contact with an alcohol treatment provider, treatment initiation, treatment completion, or change in risky alcohol use behavior. Subanalyses indicated that HERA participants, who accepted a faxed referral, were more likely to initiate contact with a treatment provider and initiate treatment for risky alcohol use, but were not more likely to continue engaging in treatment, or to complete treatment and change risky alcohol use behavior over the 3-month period following the ED visit.

Conclusions

The HERA promoted initial contact with an alcohol treatment provider and initiation of treatment for those who accepted the faxed referral, but it did not lead to reduced risky alcohol use behavior. Factors which may have limited the HERA’s impact include lack of support for the intervention by clinical staff, the low intensity of the brief and stand-alone design of the intervention, and barriers related to patient follow-through, (eg, a lack of transportation or childcare, fees for services, or schedule conflicts).

Cross-Sectional Study of Risky Substance Use by Injured Emergency Department Patients

INTRODUCTION

Survey data regarding the prevalence of risky substance use in the emergency department (ED) is not consistent. The objective of this study was to identify the prevalence of risky substance use among injured ED patients based on the Alcohol, Smoking and Substance Involvement Screening Test (ASSIST v3.0). A secondary objective was to report on the feasibility of administering the ASSIST to this population, based on the time to conduct screening.

METHODS

This cross-sectional study used screening data from a randomized controlled trial. Injured ED patients completed the ASSIST on a tablet computer, and an ASSIST score was computed that indicated the need for a brief or intensive treatment intervention (risky use) for alcohol and other substances. For a subsample, data on time to complete each step of screening was recorded.

RESULTS

Between July 2010 and March 2013, 5,695 patients completed the ASSIST. Most (92%) reported lifetime use of at least one substance and 51% reported current risky use of at least one substance. Mean time to complete the ASSIST was 5.4 minutes and screening was considered feasible even when paused for clinical care to proceed.

CONCLUSION

Estimates of risky substance use based on the ASSIST in our large sample of injured ED patients were higher than previously reported in other studies of ED patients, possibly due to the current focus on an injured population. In addition, it was feasible to administer the ASSIST to patients in the course of their clinical care.

Factors Influencing the Frequency of Emergency Department Utilization by Individuals with Substance Use Disorders

This study assessed the characteristics of individuals with substance use disorders (ISUDs) according to their frequency of emergency department (ED) utilization, and examined which variables were associated with an increase in ED visits using Andersen's model. Data linkage of administrative databanks from three sources [addiction rehabilitation centre registry, physician billing systems, and hospital discharge databank] for 4526 ISUDs was performed. Predisposing, enabling and need factors associated with number of ED visits were determined using a negative binomial regression model and generalised estimating equations. The rate of ED utilization for this population was 9.6 %. Increased number of ED visits was associated with the following variables: older age, social fragmentation, number of consultations with general practitioners, number of consultations with psychiatrists, number of consultations with other types of physicians, alcohol abuse, drug abuse, schizophrenia, anxiety disorders, personality disorders, co-occurring substance dependence and mental disorders, co-occurring substance dependence and chronic physical disorders, and co-occurring mental health disorders and chronic physical disorders. By contrast, a diagnosis of substance dependence, co-occurring drug and alcohol abuse, and a co-occurring diagnosis of substance dependence with mental health and chronic physical disorders decreased ED visits. Efforts to reduce avoidable use of EDs should focus on chronic-disease management and other related strategies aimed at reinforcing services to ISUDs in the community, especially for ISUDs with a co-occurring diagnosis of either mental health disorders or chronic physical disorders.

Factors Associated With Emergency Department Visits: A Multistate Analysis of Adult Fee-for-Service Medicaid Beneficiaries

Objective:

The objective of this study was to examine the association of patient- and county-level factors with the emergency department (ED) visits among adult fee-for-service (FFS) Medicaid beneficiaries residing in Maryland, Ohio, and West Virginia.

Methods:

A cross-sectional design using retrospective observational data was implemented. Patient-level data were obtained from 2010 Medicaid Analytic eXtract files. Information on county-level health-care resources was obtained from the Area Health Resource file and County Health Rankings file.

Results:

In adjusted analyses, the following patient-level factors were associated with higher number of ED visits: African Americans (incidence rate ratios [IRR] = 1.47), Hispanics (IRR = 1.63), polypharmacy (IRR = 1.89), and tobacco use (IRR = 2.23). Patients with complex chronic illness had a higher number of ED visits (IRR = 3.33). The county-level factors associated with ED visits were unemployment rate (IRR = 0.94) and number of urgent care clinics (IRR = 0.96).

Conclusion:

Patients with complex healthcare needs had a higher number of ED visits as compared to those without complex healthcare needs. The study results provide important baseline context for future policy analysis studies around Medicaid expansion options.

Evaluation of a brief intervention to reduce the negative consequences of drug misuse among adult emergency department patients

OBJECTIVES

Determine if a brief intervention (BI) reduces the negative consequences of drug use/misuse among adult emergency department (ED) patients, and identify patients more likely to benefit from the BI.

METHODS

This randomized, controlled trial enrolled 1026 18-64 year-old ED patients whose drug misuse indicated a needed for a BI. Differences in total Inventory of Drug Use Consequences (InDUC) scores between the treatment (BI) and control arms (no BI) were assessed every 90 days over a one-year period. Regression models were constructed to identify demographic and clinical factors associated with greater reductions in total InDUC scores.

RESULTS

Although total InDUC scores decreased for both the treatment and control arms, there were no differences in scores between the treatment and the control arms at baseline at each follow-up. In the regression analyses, participants who were not using drugs or received drug treatment in the past 90 days generally had lower InDUC scores at each follow-up.

CONCLUSIONS

Although negative consequences decreased in both study arms over time, receiving a BI did not lead to a greater reduction in the negative consequences of drug misuse than not receiving a BI. Of importance in the design of future ED drug misuse interventions, participants who were successful in stopping their drug misuse or receiving drug treatment did show fewer negative consequences of drug use/misuse.

Substance use and mental diagnoses among adults with and without type 2 diabetes: Results from electronic health records data

BACKGROUND

Comorbid diabetes and substance use diagnoses (SUD) represent a hazardous combination, both in terms of healthcare cost and morbidity. To date, there is limited information about the association of SUD and related mental disorders with type 2 diabetes mellitus (T2DM).

METHODS

We examined the associations between T2DM and multiple psychiatric diagnosis categories, with a focus on SUD and related psychiatric comorbidities among adults with T2DM. We analyzed electronic health record (EHR) data on 170,853 unique adults aged ≥18 years from the EHR warehouse of a large academic healthcare system. Logistic regression analyses were conducted to estimate the strength of an association for comorbidities.

RESULTS

Overall, 9% of adults (n=16,243) had T2DM. Blacks, Hispanics, Asians, and Native Americans had greater odds of having T2DM than whites. All 10 psychiatric diagnosis categories were more prevalent among adults with T2DM than among those without T2DM. Prevalent diagnoses among adults with T2MD were mood (21.22%), SUD (17.02%: tobacco 13.25%, alcohol 4.00%, drugs 4.22%), and anxiety diagnoses (13.98%). Among adults with T2DM, SUD was positively associated with mood, anxiety, personality, somatic, and schizophrenia diagnoses.

CONCLUSIONS

We examined a large diverse sample of individuals and found clinical evidence of SUD and psychiatric comorbidities among adults with T2DM. These results highlight the need to identify feasible collaborative care models for adults with T2DM and SUD related psychiatric comorbidities, particularly in primary care settings, that will improve behavioral health and reduce health risk.

Short-term Efficacy of a Brief Intervention to Reduce Drug Misuse and Increase Drug Treatment Utilization Among Adult Emergency Department Patients

OBJECTIVES

Although brief interventions (BIs) have shown some success for smoking cessation and alcohol misuse, it is not known if they can be applied in the emergency department (ED) to drug use and misuse. The objectives of this investigation were to assess the 3-month efficacy of a BI to reduce drug use and misuse, increase drug treatment services utilization among adult ED patients, and identify subgroups more likely to benefit from the BI.

METHODS

This randomized, controlled trial enrolled 18- to 64-year-old English- or Spanish-speaking patients from two urban, academic EDs whose responses to the Alcohol, Smoking, and Substance Involvement Screening Test indicated a need for a brief or intensive intervention. Treatment participants received a tailored BI, while control participants only completed the study questionnaires. At the 3-month follow-up, each participant's past 3-month drug use and misuse and treatment utilization were compared to his or her baseline enrollment data. Regression modeling was used to identify subgroups of patients (per demographic and clinical factors) more likely to stop or reduce their drug use or misuse or engage in drug treatment by the 3-month follow-up assessment.

RESULTS

Of the 1,030 participants, the median age was 30 years (interquartile range = 24 to 42 years), and 46% were female; 57% were white/non-Hispanic, 24.9% were black/non-Hispanic, and 15% were Hispanic. The most commonly misused drugs were marijuana, prescription opioids, cocaine/crack, and benzodiazepines. Although at follow-up the proportions of participants reporting any past 3-month drug misuse had decreased in both study arms (control 84% vs. treatment 78%), the decreases were similar between the two study arms (Δ-6.3%; 95% confidence interval [CI] = -13.0% to 0.0). In addition, at follow-up there were no differences between study arms in those who were currently receiving drug treatment (Δ1.8; 95% CI = -3.5 to 6.8), who had received treatment during the past 3 months (Δ-2.0; 95% CI = -6.5 to 2.4), or who at least contacted a treatment program (Δ 1.7; 95% CI = -2.4 to 6.1). Those whose baseline screening indicated the need for a brief instead of a more intensive intervention, and those currently engaged in drug treatment at the 3-month follow-up, were generally more likely to stop or decrease their drug use/misuse.

CONCLUSIONS

The BI employed in this study did not reduce drug use and misuse or increase treatment utilization more than the control condition over a 3-month period. Future research should help determine what role, if any, BIs should play in affecting drug use and misuse among ED patients.

Lessons learned for follow-up phone booster counseling calls with substance abusing emergency department patients

BACKGROUND

Post-visit "booster" sessions have been recommended to augment the impact of brief interventions delivered in the emergency department (ED). This paper, which focuses on implementation issues, presents descriptive information and interventionists' qualitative perspectives on providing brief interventions over the phone, challenges, "lessons learned", and recommendations for others attempting to implement adjunctive booster calls.

METHOD

Attempts were made to complete two 20-minute telephone "booster" calls within a week following a patient's ED discharge with 425 patients who screened positive for and had recent problematic substance use other than alcohol or nicotine.

RESULTS

Over half (56.2%) of participants completed the initial call; 66.9% of those who received the initial call also completed the second call. Median number of attempts to successfully contact participants for the first and second calls were 4 and 3, respectively. Each completed call lasted an average of about 22 minutes. Common challenges/barriers identified by booster callers included unstable housing, limited phone access, unavailability due to additional treatment, lack of compensation for booster calls, and booster calls coming from an area code different than the participants' locale and from someone other than ED staff.

CONCLUSIONS

Specific recommendations are presented with respect to implementing a successful centralized adjunctive booster call system. Future use of booster calls might be informed by research on contingency management (e.g., incentivizing call completions), smoking cessation quitlines, and phone-based continuing care for substance abuse patients. Future research needs to evaluate the incremental benefit of adjunctive booster calls on outcomes over and above that of brief motivational interventions delivered in the ED setting.

Using process indicators to optimize service completion of an ED drug and alcohol brief intervention program

OBJECTIVE

The strongest evidence for effectiveness of screening, brief intervention, and referral to treatment (SBIRT) programs is in primary care settings. Emergency department (ED) studies have shown mixed results. Implementation of SBIRT into ED settings is complicated by the type of patients seen and the fast-paced, high-throughput nature of the ED environment that makes it difficult to reach patients flagged for SBIRT services. This study uses data from an ED-based SBIRT program to examine the relationship between screen-positive rate, ED patient flow, and SBIRT service delivery.

METHODS

Data for the study (N = 67137) were derived from weekly reports extracted directly from one hospital's electronic health record. Measures included time and day of patient entry, drug/alcohol screen result (positive or negative), and whether the patient was reached by SBIRT specialists. Factorial analysis of variance compared variations in screen-positive rates by day and time and the percentage of patients reached by SBIRT specialists during these periods.

RESULTS

Overall, 56% of screen-positive patients received SBIRT services. Only 5% of patients offered SBIRT services refused. Day and time of entry had a significant interaction effect on the reached rate (F12,14166 =3.48, P < .001). Although patient volume was lowest between 11 pm and 7 am, screen-positive rates were highest during this period, particularly on weekends; and patients were least likely to be reached during these periods.

CONCLUSIONS

When implementing an ED-based SBIRT program, thoughtful consideration should be given to patient flow and staffing to maximize program impact and increase the likelihood of sustainability.

Malnutrition among cognitively intact, noncritically ill older adults in the emergency department

STUDY OBJECTIVE

We estimate the prevalence of malnutrition among older patients presenting to an emergency department (ED) in the southeastern United States and identify subgroups at increased risk.

METHODS

We conducted a cross-sectional study with random time block sampling of cognitively intact patients aged 65 years and older. Nutrition was assessed with the Mini Nutritional Assessment Short-Form (0 to 14 scale), with malnutrition defined as a score of 7 or less and at risk for malnutrition defined as a score of 8 to 11. The presence of depressive symptoms was defined as a Center for Epidemiological Studies Depression-10 score of 4 or more (0 to 10 scale).

RESULTS

Among 138 older adults, 16% (95% confidence interval [CI] 11% to 23%) were malnourished and 60% (95% CI 52% to 68%) were either malnourished or at risk for malnutrition. Seventeen of the 22 malnourished patients (77%) denied previously receiving a diagnosis of malnutrition. The prevalence of malnutrition was not appreciably different between men and women, across levels of patient education, or between those living in urban and rural areas. However, the prevalence of malnutrition was higher among patients with depressive symptoms (52%), those residing in assisted living (44%), those with difficulty eating (38%), and those reporting difficulty buying groceries (33%).

CONCLUSION

Among a random sample of cognitively intact older ED patients, more than half were malnourished or at risk for malnutrition, and the majority of malnourished patients had not previously received a diagnosis. Higher rates of malnutrition among individuals with depression, difficulty eating, and difficulty buying groceries suggest the need to explore multifaceted interventions.

Evaluation and treatment of migraine in the emergency department: a review

Head pain is the fifth most common reason for emergency department (ED) visits. It is second only to focal weakness as the most common reason for neurological consultation in the ED. This manuscript reviews how patients with migraine, the most common primary headache disorder for which patients seek medical treatment, are managed in the ED. We discuss existing guidelines for head imaging in patients with migraine, recommended pharmacologic treatments, and current treatment trends. We also review studies evaluating the discharge care of migraine patients in the ED. With the goal of standardizing, streamlining, and optimizing ED-based migraine care, we offer ideas for future research to improve the evaluation, treatment, and discharge care of patients who present to an ED with acute migraine.

Alcohol, tobacco, and drug use among emergency department patients

BACKGROUND

The prevalence of alcohol, tobacco, and other drug (ATOD) use among emergency department (ED) patients is high and many of these patients have unrecognized and unmet substance use treatment needs. Identification of patients in the ED with problem substance use is not routine at this time.

METHODS

We examined screening data, including standardized measures of ATOD use (HSI, AUDIT-C, DAST-10), from 14,866 ED patients in six hospitals across the United States. We expected younger age, male gender, higher triage acuity, and other substance use severity (ATOD) to be associated both with use versus abstinence and with severity of each substance use type. We used negative binomial hurdle models to examine the association between covariates and (1) substance use versus abstinence (logistic submodel) and with (2) severity among those who used substances (count submodel).

RESULTS

Rates of use and problem use in our sample were similar to or higher than other ED samples. Younger patients and males were more likely to use ATOD, but the association of age and gender with severity varied across substances. Triage level was a poor predictor of substance use severity. Alcohol, tobacco, and drug use were significantly associated with using other substances and severity of other substance use.

CONCLUSION

Better understanding of the demographic correlates of ATOD use and severity and the patterns of comorbidity among classes of substance can inform the design of optimal screening and brief intervention procedures addressing ATOD use among ED patients. Tobacco may be an especially useful predictor.

Epidemiology of emergency department visits for opioid overdose: a population-based study

OBJECTIVES

To evaluate the rate of emergency department (ED) visits for opioid overdose and to examine whether frequent ED visits for opioid overdose are associated with more hospitalizations, near-fatal events, and health care spending.

PATIENTS AND METHODS

Retrospective cohort study of adults with at least 1 ED visit for opioid overdose between January 1, 2010, and December 31, 2011, derived from population-based data of State Emergency Department Databases and State Inpatient Databases for 2 large and diverse states: California and Florida. Main outcome measures were hospitalizations for opioid overdose, near-fatal events (overdose involving mechanical ventilation), and hospital charges during the year after the first ED visit.

RESULTS

The analytic cohort comprised 19,831 unique patients with 21,609 ED visits for opioid overdose. During a 1-year period, 7% (95% CI, 7%-7%; n=1389 patients) of the patients had frequent (2 or more) ED visits, accounting for 15% (95% CI, 14%-15%; n=3167) of all opioid overdose ED visits. Middle age, male sex, public insurance, lower household income, and comorbidities (such as chronic pulmonary disease and neurological diseases) were associated with frequent ED visits (all P<.01). Overall, 53% (95% CI, 52%-54%; n=11,412) of the ED visits for opioid overdose resulted in hospitalizations; patients with frequent ED visits for opioid overdose had a higher likelihood of hospitalization (adjusted odds ratio, 3.98; 95% CI, 3.38-4.69). In addition, 10.0% (95% CI, 10%-10%; n=2161) of the ED visits led to near-fatal events; patients with frequent ED visits had a higher likelihood of a near-fatal event (adjusted odds ratio, 2.27; 95% CI, 1.96-2.66). Total charges in Florida were $208 million (95% CI, $200-$219 million).

CONCLUSION

In this population-based cohort, we found that frequent ED visits for opioid overdose were associated with a higher likelihood of future hospitalizations and near-fatal events.

The H-Impairment Index (HII): a standardized assessment of alcohol-induced impairment in the Emergency Department

BACKGROUND

Emergency Departments (EDs) care for thousands of alcohol-intoxicated patients annually. No clinically relevant bedside measures currently exist to describe degree of impairment.

OBJECTIVES

To assess a group of bedside tests ("Hack's Impairment Index [HII] score") that applies a numerical value to the degree of alcohol-induced impairment in ED patients.

METHODS

A six-month retrospective review of HII score data was performed in a convenience sample of 293 intoxicated ED patients. Patients were scored 0-4 on five tasks, divided by the maximum score (20 if all tasks completed), every 2 hours; and classified by the number of visits: Low-frequency (1 visit); Medium-frequency (2 visits); High-frequency (≥3 visits). Correlations were assessed between HII score, healthcare provider judgment of intoxication, and measured alcohol levels.

RESULTS

Study patients had 513 visits; 236 were low-frequency, 26 middle-frequency and 31 high-frequency. Clinical assessment and HII score were strongly correlated (Spearman's rho = 0.82, p << 0.001); clinical assessment and alcohol level less strongly so (rho = 0.49, p << 0.001). Among low-frequency patients, HII score and alcohol level were weakly correlated (r = 0.324, p < 0.001), with no such correlation among high-frequency visitors (r = -0.04, p = 0.89). The mean decline between serial HII scores was 0.126 (95% CI: 0.098-0.154).

CONCLUSION

This pilot study shows the HII score can be performed at the bedside of alcohol-intoxicated patients. The HII declines in a reasonably predictable manner over time; and applies a quantitative, objective assessment of alcohol impairment.

Prevalence and treatment of pain in EDs in the United States, 2000 to 2010

OBJECTIVES

To describe changes in the prevalence and severity of pain and prescribing of non-opioid analgesics in US emergency departments (EDs) from 2000 to 2010.

METHODS

Analysis of serial cross-sectional data regarding ED visits from the National Hospital Ambulatory Medical Care Survey. Visits were limited to patients ≥18 years old without malignancy. Outcome measures included annual volume of visits among adults with a primary symptom or diagnosis of pain, annual rates of patient-reported pain severity, and predictors of non-opioid receipt for non-malignant pain.

RESULTS

Rates of pain remained stable, representing approximately 45% of visits from 2000 through 2010. Patients reported pain as their primary symptom twice as often as providers reported a primary pain diagnosis (40% vs 20%). The percentage of patients reporting severe pain increased from 25% (95% confidence intervals [CI] 22%-27%) in 2003 to 40% (CI 37%-42%) in 2008. From 2000 to 2010, the proportion of pain visits treated with pharmacotherapies increased from 56% (CI 53%-58%) to 71% (CI 69%-72%), although visits treated exclusively with non-opioids decreased 21% from 28% (CI 27%-30%) to 22% (CI 20%-23%). The adjusted odds of non-opioid rather than opioid receipt were greater among visits for patients 18 to 24 years old (odds ratio [OR] 1.35, CI 1.24-1.46), receiving fewer medicines (OR 2.91, CI 2.70-3.15) and those with a diagnosis of mental illness (OR 2.24, CI 1.99-2.52).

CONCLUSIONS

Large increases in opioid utilization in EDs have coincided with reductions in the use of non-opioid analgesics and an unchanging prevalence of pain among patients.

Comparison of Objective Screening and Self-Report for Alcohol and Drug Use in Traumatically Injured Patients

Alcohol and drug use is prevalent in trauma patients. Concerns over the validity of self-reporting drug use could make non laboratory screening problematic. This study sought to validate patient self-report of substance use against objective screening to determine the reliability of self-report in trauma patients. Patients admitted to either the Trauma or Burn services who were at least 18 years old were screened for alcohol and drug use with validated screening tools. Exclusion criteria were altered mental status, non English speaking, inability to answer questions for other reasons, under police custody, or admission for < 24 hours. Results from admission Blood Alcohol Concentration BAC and Urine Drug Screen UDS were also collected and compared to self-reported use to determine its reliability. Alcohol use was queried in 128 patients, 101 of whom had a BAC drawn. Of those 101, 34 (33.7%) had a BAC > 0 mg%. Alcohol Use Disorder Identification Test AUDIT screening revealed 13 (12.9%) patients who were self-reported non drinkers, none of which had a BAC > 0 mg%. Drug use was queried in 133 patients, 93 of whom had a UDS. A positive was found in 26 (28.0%) of the patients, only 12 (46.2%) of whom reported drug use in the past year. Though substance use in trauma patients is prevalent, self-report screening techniques for drugs may be inadequate at determining those patients whom could benefit from brief interventions while in the hospital. Further investigation is needed to determine the discrepancy between alcohol and drug use screening in trauma patients and more acceptable means of drug use discussion.

Alcohol and drug use disorders among adults in emergency department settings in the United States

STUDY OBJECTIVE

Improving identification and treatment for substance use disorders is a national priority, but data about various drug use disorders encountered in emergency departments (EDs) are lacking. We examine past-year substance use and substance use disorders (alcohol, 9 drug classes) among adult ED users. Prevalences of substance use and substance use disorders among ED nonusers are calculated for reference purposes.

METHODS

Using data from the 2007 to 2009 National Surveys on Drug Use and Health, we assessed substance use disorders among noninstitutionalized adults aged 18 years or older who responded to standardized survey questions administered by audio computer-assisted self-interviewing methods.

RESULTS

Of all adults (N=113,672), 27.8% used the ED in the past year. ED users had higher prevalences than ED nonusers of coexisting alcohol and drug use (15.2% versus 12.1%), drug use (any drug, 16.9% versus 13.0%; marijuana, 12.1% versus 9.7%; opioids, 6.6% versus 4.1%), and alcohol or drug disorders (11.0% versus 8.5%). Among substance users, the ED group on average spent more days using drugs than the non-ED group; ED users manifested higher conditional rates of substance use disorders than ED nonusers (alcohol or drugs, 15.9% versus 11.7%; marijuana, 16.6% versus 13.2%; cocaine, 33.2% versus 22.3%; opioids, 20.6% versus 10.0%; stimulants, 18.6% versus 9.2%; sedatives, 35.0% versus 4.4%; tranquilizers, 12.4% versus 5.2%). Regardless of ED use status, substance-using young adults, men, and less-educated adults showed increased odds of having a substance use disorder.

CONCLUSION

Drug use is prevalent and combined with high rates of drug use disorders among drug users treated in the ED.

A descriptive comparison of alcohol-related presentations at a large urban hospital center from 1902 to 2009

Although alcohol use has long been a significant cause of hospital presentations, little is published regarding the long-term demographic changes that have occurred at a single hospital site. To address this deficit, we prospectively studied all acute alcohol-related presentations to Bellevue Hospital Center (New York, NY) and compared this contemporary data set with one from the same institution from 1902 to 1935. We prospectively identified all patients presenting to the emergency department because of acute alcohol use over an 8-week period in 2009. We described the basic attributes of patients presenting currently because of alcohol and compared these data to those previously described between 1902 and 1935. We also compared our census data with contemporaneous data from all patients presenting to this hospital site. During the study period, 560 patients presented because of acute alcohol use which extrapolated to an estimated 3,800 patients over the calendar year. This compares to 7,600 presentations recorded annually early in the twentieth century. Twelve percent of patients in 2009 were female as compared to 18 % of patients between 1934 and 1935. Patients with alcohol-related presentations in 2009 were more likely to be admitted than contemporaneous patients without an alcohol-related presentation (30 vs. 19 % admitted; p < 0.001). Since first measured 110 years ago at one large New York City hospital, alcohol-related presentations remain common representing 5 % of all emergency department visits. This demonstrates alcoholism's continuing toll on society's limited medical resources and on public health as a whole.

Screening for alcohol and drug use disorders among adults in primary care: a review

BACKGROUND: The Patient Protection and Affordable Care Act of 2010 supports integration of substance abuse interventions and treatments into the mainstream health care system. Thus, effective screening and intervention for substance use disorders in health care settings is a priority. OBJECTIVE: This paper reviews the prevalence of alcohol and drug use disorders (abuse or dependence) in primary care settings and emergency departments, as well as current screening tools and brief interventions. METHODS: MEDLINE was searched using the following keywords: alcohol use, alcohol use disorder, drug use, drug use disorder, screening, primary care, and emergency departments. Using the related-articles link, additional articles were screened for inclusion. This review focuses on alcohol and drug use and related disorders among adults in primary care settings. CONCLUSION: Screening, brief intervention, and referral for treatment are feasible and effective in primary care settings, provided that funding for screening is available, along with brief interventions and treatment facilities to which patients can be referred and treated promptly.

A brief intervention reduces hazardous and harmful drinking in emergency department patients

STUDY OBJECTIVE

Brief interventions have been shown to reduce alcohol use and improve outcomes in hazardous and harmful drinkers, but evidence to support their use in emergency department (ED) patients is limited. The use of research assessments in studies of brief interventions may contribute to uncertainty about their effectiveness. Therefore we seek to determine (1) if an emergency practitioner-performed Brief Negotiation Interview or a Brief Negotiation Interview with a booster reduces alcohol consumption compared with standard care; and (2) the impact of research assessments on drinking outcomes using a standard care-no-assessment group.

METHODS

We randomized 889 adult ED patients with hazardous and harmful drinking. A total of 740 received an emergency practitioner-performed Brief Negotiation Interview (n=297), a Brief Negotiation Interview with a 1-month follow-up telephone booster (Brief Negotiation Interview with booster) (n=295), or standard care (n=148). We also included a standard care with no assessments (n=149) group to examine the effect of assessments on drinking outcomes. Primary outcomes analyzed with mixed-models procedures included past 7-day alcohol consumption and 28-day binge episodes at 6 and 12 months, collected by interactive voice response. Secondary outcomes included negative health behaviors and consequences collected by telephone surveys.

RESULTS

The reduction in mean number of drinks in the past 7 days from baseline to 6 and 12 months was significantly greater in the Brief Negotiation Interview with booster (from 20.4 [95% confidence interval {CI} 18.8 to 22.0] to 11.6 [95% CI 9.7 to 13.5] to 13.0 [95% CI 10.5 to 15.5]) and Brief Negotiation Interview (from 19.8 [95% CI 18.3 to 21.4] to 12.7 [95% CI 10.8 to 14.6] to 14.3 [95% CI 11.9 to 16.8]) than in standard care (from 20.9 [95% CI 18.7 to 23.2] to 14.2 [95% CI 11.2 to 17.1] to 17.6 [95% CI 14.1 to 21.2]). The reduction in 28-day binge episodes was also greater in the Brief Negotiation Interview with booster (from 7.5 [95% CI 6.8 to 8.2] to 4.4 [95% CI 3.6 to 5.2] to 4.7 [95% CI 3.9 to 5.6]) and Brief Negotiation Interview (from 7.2 [95% CI 6.5 to 7.9] to 4.8 [95% CI 4.0 to 5.6] to 5.1 [95% CI 4.2 to 5.9]) than in standard care (from 7.2 [95% CI 6.2 to 8.2] to 5.7 [95% CI 4.5 to 6.9] to 5.8 [95% CI 4.6 to 7.0]). The Brief Negotiation Interview with booster offered no significant benefit over the Brief Negotiation Interview alone. There were no differences in drinking outcomes between the standard care and standard care-no assessment groups. The reductions in rates of driving after drinking more than 3 drinks from baseline to 12 months were greater in the Brief Negotiation Interview (38% to 29%) and Brief Negotiation Interview with booster (39% to 31%) groups than in the standard care group (43% to 42%).

CONCLUSION

Emergency practitioner-performed brief interventions can reduce alcohol consumption and episodes of driving after drinking in hazardous and harmful drinkers. These results support the use of brief interventions in ED settings.

A systematic review of emergency department technology-based behavioral health interventions

OBJECTIVES

This systematic review evaluated the evidence for use of computer technologies to assess and reduce high-risk health behaviors in emergency department (ED) patients.

METHODS

A systematic search was conducted of electronic databases, references, key journals, and conference proceedings. Studies were included if they evaluated the use of computer-based technologies for ED-based screening, interventions, or referrals for high-risk health behaviors (e.g., unsafe sex, partner violence, substance abuse, depression); were published since 1990; and were in English, French, or Spanish. Study selection and assessment of methodologic quality were performed by two independent reviewers. Data extraction was performed by one reviewer and then independently checked for completeness and accuracy by a second reviewer.

RESULTS

Of 17,744 unique articles identified by database search, 66 underwent full-text review, and 20 met inclusion criteria. The greatest number of studies targeted alcohol/substance use (n = 8, 40%), followed by intentional or unintentional injury (n = 7, 35%) and then mental health (n = 4, 20%). Ten of the studies (50%) were randomized controlled trials; the remainder were observational or feasibility studies. Overall, studies showed high acceptability and feasibility of individual computer innovations, although study quality varied greatly. Evidence for clinical efficacy across health behaviors was modest, with few studies addressing meaningful clinical outcomes. Future research should aim to establish the efficacy of computer-based technology for meaningful health outcomes and to ensure that effective interventions are both disseminable and sustainable.

CONCLUSIONS

The number of studies identified in this review reflects recent enthusiasm about the potential of computers to overcome barriers to behavioral health screening, interventions, and referrals to treatment in the ED. The available literature suggests that these types of tools will be feasible and acceptable to patients and staff.

Alcohol and drug dependence symptom items as brief screeners for substance use disorders: results from the Clinical Trials Network

AIM

To address an urgent need for screening of substance use problems in medical settings, we examined substance-specific dependence criteria as potential brief screeners for the detection of patients with a substance use disorder (SUD).

METHODS

The sample included 920 opioid-dependent adults who were recruited from outpatient treatment settings at 11 programs in 10 U.S. cities and who completed intake assessments of SUDs for a multisite study of the National Drug Abuse Treatment Clinical Trials Network (CTN003). Data were analyzed by factor analysis, item response theory (IRT), sensitivity, and specificity procedures.

RESULTS

Across all substances (alcohol, amphetamines, cannabis, cocaine, sedatives), withdrawal was among the least prevalent symptoms, while taking large amounts and inability to cut down were among the most prevalent symptoms. Items closely related to the latent trait of a SUD showed good-to-high values of area under the receiver operating characteristic curve in identifying cases of a SUD; IRT-defined severe and less discriminative items exhibited low sensitivity in identifying cases of a SUD (withdrawal for all substances; time using for alcohol and sedatives; giving up activities for sedatives).

CONCLUSIONS

Study results suggest that withdrawal and time using are much less reliable indicators for a SUD than taking larger amounts than intended and inability to cut down and that the latter two items should be studied further for consideration in developing a simplified tool for screening patients for SUDs in medical settings. These findings have implications for the use of common health indicators in electronic health records systems to improve patient care.

Electronic health records: essential tools in integrating substance abuse treatment with primary care

While substance use problems are considered to be common in medical settings, they are not systematically assessed and diagnosed for treatment management. Research data suggest that the majority of individuals with a substance use disorder either do not use treatment or delay treatment-seeking for over a decade. The separation of substance abuse services from mainstream medical care and a lack of preventive services for substance abuse in primary care can contribute to under-detection of substance use problems. When fully enacted in 2014, the Patient Protection and Affordable Care Act 2010 will address these barriers by supporting preventive services for substance abuse (screening, counseling) and integration of substance abuse care with primary care. One key factor that can help to achieve this goal is to incorporate the standardized screeners or common data elements for substance use and related disorders into the electronic health records (EHR) system in the health care setting. Incentives for care providers to adopt an EHR system for meaningful use are part of the Health Information Technology for Economic and Clinical Health Act 2009. This commentary focuses on recent evidence about routine screening and intervention for alcohol/drug use and related disorders in primary care. Federal efforts in developing common data elements for use as screeners for substance use and related disorders are described. A pressing need for empirical data on screening, brief intervention, and referral to treatment (SBIRT) for drug-related disorders to inform SBIRT and related EHR efforts is highlighted.

Alcohol and drug use among patients presenting to an inner-city emergency department: a latent class analysis

The inner city Emergency Department (ED) provides a window of opportunity for screening for alcohol and other drug misuse and substance use disorders (SUDs), in order to facilitate linkage for individuals who are in need of services targeting such issues. The majority of prior work in this area has focused on alcohol use. This study used latent class analyses to characterize substance use/SUDs among adults presenting to the ED for medical complaints or injuries. Participants (n=14,557; 77% participation; 45% male; 54% African-American) completed a computerized survey assessing demographics, health functioning, and substance use/SUDs. Although injured patients were significantly more likely to use tobacco, alcohol, and marijuana, and were more likely to have an alcohol use disorder, presenting complaint was not related to other drug use/diagnoses. Five latent classes were identified: (1) low users/SUDs (65.9%) (2) binge drinkers (24.3%), (3) marijuana users/SUD (3.5%), (4) cocaine users/SUD (2.9%), and (5) poly-drug users (3.3%). Compared to class 1, participants in the other classes were younger, male, without health insurance, with poor mental health functioning, tobacco users, and had prior substance use treatment. African-Americans were most likely to be in classes 3 or 4 and employed participants were most likely to be in class 2. In comparison to class 1, classes 2 and 3 reported better physical health; class 2 was more likely to present for injury whereas class 5 was more likely to present for a medical complaint. ED-based screening and interventions approaches need to address the co-occurrence of alcohol, illicit drug, and psychoactive prescription drug use.

Substance use, depression, and mental health functioning in patients seeking acute medical care in an inner-city ED

The study investigated the behavioral health of a consecutive sample of 5,641 adult emergency department (ED) patients aged 19 through 60 presenting for medical care in a large, inner-city hospital ED. Twenty-three percent met the criteria for major depression; average mental health functioning, as measured by the mental health component of the SF-12, was half of a standard deviation lower than in the general population; 15% met the criteria for alcohol or drug abuse/dependence in the past year. Comorbidity was high. These behavioral health disorders may complicate treatment and diagnosis of the chief presenting complaint. These findings, coupled with the high rates of these disorders, suggest the importance of screening and either beginning appropriate treatment or offering appropriate referral for such disorders in ED settings.

Frequency of 5+/4+ drinks as a screener for drug use and drug-use disorders

OBJECTIVE

The objective of this study was to test the ability of a question on frequency of drinking 5+ (for men) or 4+ (for women) drinks to screen for drug use and drug-use disorders (DUDs) in a general population sample.

METHOD

Using data collected in 2001-2002 from a representative U.S. adult population sample (N= 43,093), including a subsample of those with past-year emergency-department use (n = 8,525), past-year frequency of drinking 5+/4+ drinks was evaluated as a screener for drug use and DUDs for four categories of illicit drugs.

RESULTS

Sensitivities and specificities of the 5+/4+ drinks screener were 72.4% and 76.6% for any drug dependence, 71.9% and 77.3% for any DUD, and 63.3% and 78.9% for any drug use in the general population. Sensitivities and specificities were higher for marijuana and cocaine/crack and lowest for illicit prescription drugs. Optimal screening cut-points were once a month or more for cocaine/crack dependence, either once or more a month or seven or more times a year for cocaine/crack DUDs, seven or more times a year for cocaine/crack use, and once or more a year for the other drug use and DUD measures. Sensitivity and specificity were similar among adults who had visited an emergency department in the past year, and the optimal screening cutpoints were identical.

CONCLUSIONS

Past-year frequency of drinking 5+/4+ drinks was quite accurate as a screener for past-year marijuana and cocaine/crack use and DUDs, but it was less accurate for illicit prescription drug use and DUDs. Its drug-screening potential can be thought of as "added value" from an item already likely to be asked in the interest of detecting problem drinking. Future work may consider using the alcohol consumption screener as a starting point, with follow-up questions to assess illicit drug use among those who screen positive.

Intervention attendance among emergency department patients with alcohol- and drug-use disorders

OBJECTIVE

The emergency department (ED) visit provides a window of opportunity for screening and linkage to services for inner-city adults with substance-use disorders (SUDs). This article examines predictors of intervention attendance among ED patients who screen positive for an SUD (alcohol or other drug).

METHOD

As part of a large randomized control trial, medical and injured patients (ages 19-60) in an inner-city ED completed a computerized screening survey. Based on random assignment, those screening positive for an SUD either were scheduled to attend a post-discharge intervention or received a referral brochure. Interventions (brief motivational intervention vs. case management intervention) focused on linking participants to substance-use treatment. Independent variables assessed included demographics, ED visit reason, health functioning, readiness to change, self-efficacy, and substance use. Intervention attendance (yes/no) was the dependent variable.

RESULTS

Overall, 957 (62.3% male; 58.3% African-American; M(age) = 33.2 years) were randomized to interventions (brief motivational intervention/case management intervention) and are the focus of subsequent analyses. There were no differences in the pattern of predictors of intervention attendance for brief motivational intervention versus case management intervention. Bivariate analyses compared those who attended the post-ED intervention with those who did not attend. Participants who attended the intervention (50%) were significantly more likely to be older, unmarried, insured, unemployed, and in the "action" stage of change.

CONCLUSIONS

The present findings highlight the relative importance of assessing and attending to readiness to change as well as demographic factors such as insurance and employment (and potentially associated barriers) in ED-based screening, brief intervention, and referral to treatment protocols.

Patterns of substance abuse treatment seeking following cocaine-related emergency department visits

Chest pain is the most common medical complaint among cocaine-using emergency department (ED) patients. Correlates of substance abuse treatment seeking were examined using 3-month post-discharge surveys from 170 ED patients admitted with cocaine-related chest pain. Four treatment categories were specified as the dependent variable in an ordered logistic regression: no treatment (74.7%), informal treatment only (7.1%), formal treatment only (5.9%), and both formal and informal treatment (12.4%). The following variables were found to be positively associated with a higher treatment category: frequency of cocaine use (OR = 1.07, CI(95) = 1.01-1.15, p = 0.03), global severity index (OR = 2.26, CI(95) = 1.04-4.90, p = 0.04), number of endorsed stigma barriers (OR = 4.40, CI(95) = 1.41-13.78, p = 0.01), interpersonal consequences (OR = 1.41, CI(95) = 1.01-1.88, p = 0.02), and pre-baseline informal treatment (OR = 6.69, CI(95) = 1.58-28.36, p = 0.01). Physical consequences were found to be negatively associated with a higher treatment category (OR = 0.63, CI(95) = 0.47-0.85, p < 0.01). ED visits for cocaine-related chest pain represent missed opportunities to link patients to substance abuse treatment, and interventions are needed to motivate patients to seek care.

Use of an administrative data set to determine optimal scheduling of an alcohol intervention worker

BACKGROUND

Brief alcohol interventions are efficacious in reducing alcohol-related consequences among emergency department (ED) patients. Use of non-clinical staff may increase alcohol screening and intervention; however, optimal scheduling of an alcohol intervention worker (AIW) is unknown.

OBJECTIVES

Determine optimal scheduling of an AIW based on peak discharge time of alcohol-related ED visits.

METHODS

Discharge times for consecutive patients with an alcohol-related diagnosis were abstracted from an urban ED's administrative data set from September 2005 through August 2007. Queuing theory was used to identify optimal scheduling. Data for weekends and weekdays were analyzed separately. Stationary independent period-by-period analysis was performed for hourly periods. An M/M/s queuing model, for Markovian inter-arrival time/Markovian service time/and potentially more than one server, was developed for each hour assuming: 1) a single unlimited queue; 2) 75% of patients waited no longer than 30 min for intervention; 3) AIW spent an average 20 min/patient. Estimated average utilization/hour was calculated; if utilization/hour exceeded 25%, AIW staff was considered necessary.

RESULTS

There were 2282 patient visits (mean age 38 years, range 11-84 years). Weekdays accounted for 45% of visits; weekends 55%. On weekdays, one AIW from 6:00 a.m.-9:00 a.m. (max utilization 42%/hour) would accommodate 28% of weekday alcohol-related patients. On weekends, 5:00 a.m.-11:00 a.m. (max utilization 50%), one AIW would cover 54% of all weekend alcohol-related visits. During other hours the utilization rate falls below 25%/hour.

CONCLUSIONS

Evaluating 2 years of discharge data revealed that 30 h of dedicated AIW time--18 weekend hours (5:00 a.m.-11:00 a.m.), 12 weekday hours (6:00 a.m.-9:00 a.m.)--would allow maximal patient alcohol screening and intervention with minimal additional burden to clinical staff.

Suicide and unintentional poisoning mortality trends in the United States, 1987-2006: two unrelated phenomena?

BACKGROUND

Two counter trends in injury mortality have been separately reported in the US in recent times - a declining suicide rate and a rapidly rising unintentional poisoning mortality rate. Poisoning suicides are especially difficult to detect, and injury of undetermined intent is the underlying cause-of-death category most likely to reflect this difficulty. We compare suicide and poisoning mortality trends over two decades in a preliminary assessment of their independence and implications for suicide misclassification.

METHODS

Description of overall and gender- and age-specific trends using national mortality data from WISQARS, the Web-based Injury Statistics Query and Reporting System, maintained by the Centers for Disease Control and Prevention (CDC). Subjects were the 936,633 residents dying in the 50 states and the District of Columbia between 1987 and 2006 whose underlying cause of death was classified as suicide, unintentional poisoning, or injury mortality of undetermined intent.

RESULTS

The official US suicide rate declined 18% between 1987 and 2000, from 12.71 to 10.43 deaths per 100,000 population. It then increased to 11.15 deaths per 100,000 by 2006, a 7% rise. By contrast to these much smaller rate changes for suicide, the unintentional poisoning mortality rate rose more than fourfold between 1987 and 2006, from 2.19 to 9.22 deaths per 100,000. Only the population aged 65 years and older showed a sustained decline in the suicide rate over the entire observation period. Consistently highest in gender-age comparisons, the elderly male rate declined by 35%. The elderly female rate declined by 43%. Unlike rate trends for the non-elderly, both declines appeared independent of corresponding mortality trends for unintentional poisoning and poisoning of undetermined intent. The elderly also deviated from younger counterparts by having a smaller proportion of their injury deaths of undetermined intent classified as poisoning. Poisoning manifested as a less common method of suicide for this group than other decedents, except for those aged 15-24 years. Although remaining low, the undetermined poisoning mortality rate increased over the observation period.

CONCLUSIONS

The official decline in the suicide rate between 1987 and 2000 may have been a partial artifact of misclassification of non-elderly suicides within unintentional poisoning mortality. We recommend in-depth national, regional, and local population-based research investigations of the poisoning-suicide nexus, and endorse calls for widening the scope of the definition of suicide and evaluation of its risk factors.

Integrating Project ASSERT: a screening, intervention, and referral to treatment program for unhealthy alcohol and drug use into an urban emergency department

OBJECTIVES

The objective was to evaluate the effects of Project Alcohol and Substance Abuse Services Education and Referral to Treatment (ASSERT), an emergency department (ED)-based screening, brief intervention, and referral to treatment program for unhealthy alcohol and other drug use.

METHODS

Health promotion advocates (HPAs) screened ED patients for alcohol and/or drug problems 7 days a week using questions embedded in a general health questionnaire. Patients with unhealthy drinking and/or drug use received a brief negotiation interview (BNI), with the goal of reducing alcohol/drug use and/or accepting a referral to a specialized treatment facility (STF), depending on severity of use. Patients referred to an STF were followed up at 1 month by phone or contact with the STF to determine referral completion and enrollment into the treatment program.

RESULTS

Over a 5-year period (December 1999 through December 2004), 22,534 adult ED patients were screened. A total of 10,246 (45.5%) reported alcohol consumption in the past 30 days, of whom 5,533 (54%) exceeded the National Institute on Alcohol Abuse and Alcoholism (NIAAA) guidelines for low-risk drinking. Use of at least one illicit drug was reported by 3,530 patients (15.7%). Over one-fourth of screened patients received BNIs (6,266, or 27.8%). Of these, 3,968 (63%) were referred to an STF. Eighty-three percent of patients were followed at 1 month, and 2,159 (65%) had enrolled in a program. Patients who received a direct admission to an STF were 30 times more likely to enroll than those who were indirectly referred (odds ratio = 30.71; 95% confidence interval = 18.48 to 51.04). After 3 years, funding for Project ASSERT was fully incorporated into the ED budget.

CONCLUSIONS

Project ASSERT has been successfully integrated into an urban ED. A direct, facilitated referral for patients with alcohol and other drug problems results in a high rate of enrollment in treatment programs.
