Urine testing for drugs of abuse: a survey of suburban parent-adolescent dyads

A review of guidelines on home drug testing web sites for parents

OBJECTIVES

To update and extend prior work reviewing Web sites that discuss home drug testing for parents, and assess the quality of information that the Web sites provide, to assist them in deciding when and how to use home drug testing.

METHODS

We conducted a worldwide Web search that identified 8 Web sites providing information for parents on home drug testing. We assessed the information on the sites using a checklist developed with field experts in adolescent substance abuse and psychosocial interventions that focus on urine testing.

RESULTS

None of the Web sites covered all the items on the 24-item checklist, and only 3 covered at least half of the items (12, 14, and 21 items, respectively). The remaining 5 Web sites covered less than half of the checklist items. The mean number of items covered by the Web sites was 11.

CONCLUSIONS

Among the Web sites that we reviewed, few provided thorough information to parents regarding empirically supported strategies to effectively use drug testing to intervene on adolescent substance use. Furthermore, most Web sites did not provide thorough information regarding the risks and benefits to inform parents' decision to use home drug testing. Empirical evidence regarding efficacy, benefits, risks, and limitations of home drug testing is needed.

Screening instruments for substance use and brief interventions targeting adolescents in primary care: a literature review

BACKGROUND

A review of the literature was conducted to examine substance use screening instruments commonly used with adolescents in medical settings, their comparative usefulness, and SBIRT (Screening, Brief Intervention, and Referral to Treatment).

METHODS

We screened two databases (Ovid MEDLINE and PsycINFO) targeting journal articles dealing with screening for alcohol and drug use in adolescence as well as adolescent SBIRT.

RESULTS

Adolescents preferred paper forms and computerized questionnaires over interviews with physicians or nurses. The CRAFFT was the best studied instrument for screening for alcohol/drug use and related problems, and is the only tool with data to support its use in medical settings. Other screening instruments require more testing/evaluation in more representative samples of adolescents in primary care settings. Long term follow-up data to establish the efficacy of SBIRT in adolescence are not available. Innovative computerized approaches to screening for substance use in this population have recently been proposed. Although promising, they require further evaluation.

CONCLUSIONS

The CRAFFT has the most consistent data to support its use in primary care settings. The effects of SBIRT in adolescence have not been adequately evaluated. Adolescents' opinions and preferences for SBIRT should be studied to improve their acceptance.

Random student drug testing as a school-based drug prevention strategy

AIM

This paper describes the goals and current practice of school-based random student drug testing (RSDT) as part of an overall drug prevention strategy, briefly explores the available literature evaluating its effectiveness and discusses the controversies related to RSDT.

METHOD

The authors describe the rationale for RSDT programs and the prevalence of RSDT and other drug testing programs in schools. Eight major criticisms and controversies in RSDT are discussed, including those related to acceptance of RSDT, program effectiveness, costs, legality and effects of drug testing on students. The limitations of the current literature are explored.

FINDINGS

Although there is limited empirical evidence to support or refute the efficacy of RSDT in schools, there remains substantial opposition to such programs, which may contribute to the paucity of empirical studies of RSDT.

CONCLUSIONS

Rigorous long-term evaluations are needed to evaluate the effectiveness of various versions of RSDT programs to prevent drug use and identify students in need of assistance to become and stay drug-free.

Acceptability of drug testing in an outpatient substance abuse program for adolescents

BACKGROUND

Laboratory drug testing programs may be effective in reducing substance use by adolescents, but developmentally appropriate programs have not been described, and it is unknown if adolescents would be willing to participate in drug testing.

OBJECTIVE

To describe a drug testing protocol for adolescents and report on acceptance rate by patients participating in an outpatient adolescent substance abuse program.

METHODS

Eligible adolescents participating in an outpatient substance abuse treatment program were offered a random laboratory drug testing program that is described in detail in this manuscript. We recorded whether they accepted and, if not, the reason for refusal.

RESULTS

Of the first 114 eligible patients, 67 (59%) agreed to participate in a drug testing program (PDT).

CONCLUSIONS

A majority of adolescents participating in an outpatient drug treatment program agreed to participate in a drug testing program that requires frequent urine specimens and reports results to parents. Future studies should determine how this program affects treatment outcomes and whether this program is feasible in primary care.

Urine toxicology screening in Austrian trauma patients: a prospective study

INTRODUCTION

The question as to whether the patient consumed drugs prior to the trauma and which drugs were consumed, is of prime importance for the anesthesia required during surgery. However, many patients are unwilling or unable (including those with multiple trauma or impaired consciousness, or unconscious patients) to answer this question. The purpose of our prospective multicenter study was to collect data about drug consumption in Austria to determine whether drugs are identifiable in the urine of recently injured individuals and to establish the types of drugs consumed.

MATERIALS AND METHODS

This prospective study included severely and moderately injured patients admitted to the Lorenz Boehler Trauma Hospital (Vienna, Austria), the Trauma Hospital Linz (Linz, Austria) and the Department of Trauma Surgery of the General Hospital Horn (Horn, Austria) during an 18-month period (October 2003-March 2005). All patients were suffering from injuries urgently requiring surgery. Urine samples were gained from all patients immediately after admission. Urinary samples were tested by Immuno-Assay (Triage 8 Immuno-Assay, Biosite, San Diego, USA). Urine samples were screened simultaneously for opiates, methadone, cocaine, barbiturates, amphetamines, cannabinoids, benzodiazepines and tricyclic antidepressants.

RESULTS

Our prospective study included a total of 664 patients (320 from Vienna, 193 from the city of Linz, and 151 from Horn). Six hundred and forty-two patients were moderately injured (ISS < 16), suffering mostly from injuries to the extremities (504 patients) and 22 patients were severely injured (ISS > 16). Of the 664 patients, 178 (26.8%) tested positive for one or more drugs. The drugs most commonly detected were benzodiazepines (111 patients, 16.7%), cannabinoides (39 patients, 6%), tricyclic antidepressants (28, 4.2%) and opiates (26, 3.9%).

CONCLUSION

Drug use is widespread in patients presenting to urban trauma centers in Austria. Physicians should maintain a high index of suspicion that their patients may be intoxicated and should perform drug testing routinely.

Drug testing of adolescents in general medical clinics, in school and at home: physician attitudes and practices

PURPOSE

To determine (1) whether physicians agree with recommendations for home and school drug screening, (2) under what circumstances physicians recommend urine drug tests for adolescents, and (3) how physicians manage adolescent patients with positive results. Few clinical practice guidelines have been published on urine drug testing of adolescents, and it is not known when physicians recommend this procedure or how they manage positive results.

METHODS

Multi-modal survey of a nationally representative sample of physicians conducted April-July 2004. We computed simple frequencies and used backwards selection logistical regression to determine if there were differences in agreement or practices among physicians from different specialties (pediatrics, family medicine, adolescent medicine) or by demographic factors (physician age, gender, practice type or location).

RESULTS

A total of 359 physicians (43% after eliminating ineligibles) completed the survey. Thirty-eight percent would recommend a drug test if were required to return to school, 41% if a parent was concerned, and 46% based on history (without a parent's concern). Forty-eight percent of physicians would share a positive drug test result with parents. A large majority (83%) disagreed with high school drug testing programs.

CONCLUSIONS

There is little consensus among physicians regarding the indications for drug testing in the general medical clinic. However, most disagree with school drug testing programs. There is little consistency among physicians in how to proceed when a urine drug test is positive. Professional organizations should consider publishing clinical practice guidelines in order to assist physicians in using this procedure effectively.

EPIDEMIOLOGY OF SUBSTANCE USE IN A REPRESENTATIVE SAMPLE OF 18-YEAR-OLD MALES

AIMS

To assess recent drug use through urine testing as well as the prevalence of tobacco and alcohol dependence among young males and to analyse the associations between tobacco dependence and cannabis use (delta-9-tetrahydrocannabinol, THC), tobacco dependence, and alcohol dependence as well as between THC use and other illicit drug use.

METHODS

Urine samples were collected, and nicotine and alcohol questionnaires were administered. Carbon monoxide was assessed in exhaled air. Data from young males from representative, selected districts of Lower Austria were recorded during the annual physical examination for mandatory military service. Out of all 18-year-old males in Austria 3.8% (n = 1902) were included in the study. Prevalence of recent illicit drug use, tobacco dependence (heavy smoking index, HSI), alcohol dependence (The 4-item cutting down, annoyance by criticism, guilty feeling, and eye-openers (CAGE) questionnaire), and associations between substance categories by means of logistic regression analyses were calculated.

RESULTS

Alcohol abuse was found in 15.1% and alcohol dependence was found in 3.2%. According to the HSI 51.5% of males reported daily smoking, of whom 43.7% showed a mild level, and 7.8% a high level, of nicotine dependence. About 5.1% of the sample evidenced THC in urine. Opiates were identified in 2.7% of urine samples. Smokers showed a higher risk of THC use. THC users had a tendency to use cocaine and amphetamines more frequently than THC abstainers.

CONCLUSION

Nicotine and alcohol dependence is common among young males. Biological assessment of illicit drug use seems to confirm previous questionnaire-based findings of associations between THC use and other illicit drugs. Urine testing seems to be an adequate method to analyse associations of THC use and other illicit drugs. In combination with questionnaires urine testing may be used for the assessment of associations of tobacco dependence and recent illicit drug use based on epidemiological surveys.
