Health status at entry to methadone maintenance treatment using the SF-36 health survey questionnaire

Evaluation of functional status among patients undergoing maintenance treatments for opioid use disorders

Background

Methadone and buprenorphine are the most prevalent types of opioid maintenance programs in Andalusia. The main objective is comparing the functional status of patients with pharmacological opioid maintenance treatments according to different socio-demographic characteristic, health and disabilities domains and sexual difficulties.

Methods

A total of 593 patients from the Andalusia community, 329 were undergoing methadone treatment and 264 were undergoing buprenorphine treatment. The patients were interviewed by socio-demographic and opioid-related variables, assessed by functioning, disability and health domains (WHODAS 2.0.) and for sexual problems (PRSexDQ-SALSEX).

Results

We found significant differences in the socio-demographic and the opioid-related variables as the onset of opioid use, being on previous maintenance programs, opioid intravenous use, the length of previous maintenance programs, polydrug use and elevated seroprevalence rates (HCV and HIV) between the methadone group and the buprenorphine group. Regarding health and disability domains there were differences in the Understanding and communication domain, Getting around domain, Participation in society domain and in the WHODAS 2.0. simple and complex score, favoring buprenorphine-treated patients. The methadone group referred elevated sexual impairments compared with the buprenorphine group. Opioid-related variables as seroprevalence rates, other previous lifetime maintenance program, the daily opioid dosage and the daily alcohol use are the most discriminative variables between both groups. Participation in society variables and sexual problems were the most important clinical variables in distinguishing the methadone group from the buprenorphine group regarding their functional status.

Conclusions

The methadone group showed higher prevalence in opioid dependence-related variables, elevated disabilities in participation in society activities and sexual problems compared with the buprenorphine group. This study shows the importance of carry out a functional evaluation in the healthcare follow-up, especially in those areas related with social activity and with sexual problems.

Efficacy of Electroacupuncture Combined with Auricular Point Pressing in Improving Mental Well-Being among Individuals with Heroin Use Disorder: A Randomized Controlled Crossover Trial and Pilot Study

Objective

To evaluate the clinical efficacy of combining electroacupuncture with auricular point pressing in improving quality of life of individuals with heroin use disorder undergoing methadone maintenance treatment.

Design

A randomized controlled crossover trial.

Subjects

50 participants were recruited from Taipei City Hospital, Linsen Chinese Medicine and Kunming branches, and randomly allocated to treatment groups.

Method

The 36-Item Short Form Health Survey (SF-36) was used. Group A received electroacupuncture at the Hegu (LI4) and Zusanli (ST36) and auricular point pressing on Ear Shenmen, and Group B received only auricular point pressing on Ear Shenmen biweekly for 4 weeks. After a 1-week washout period, crossover of the groups was performed.

Results

The SF-36 mental component scores of the combined treatment group improved relative to the single treatment group (11.09 vs. 10.33, p=0.023). Methadone dosage was reduced in both groups (combined therapy group: 8.58 ± 4.17/7.76 ± 4.11 (baseline/posttreatment) vs. single therapy group: 8.36 ± 4.20/8.30 ± .28, p=0.001).

Conclusion

Combined therapy of high-frequency electroacupuncture with auricular point pressing had better efficacy in enhancing quality of life, especially for mental well-being, and in gradually reducing methadone dosage.

The Discrimination Against, Health Status and Wellness of People Who Use Drugs in Italian Services: A Survey

Background and Objectives: The aims of this study are to: describe the sociodemographic characteristics and typology of drug addiction among people who use drugs that attend the Servizio per le Dipendenze (SerD), and evaluate the competence and ability of these rehabilitation services to improve their health status and wellness. Materials and Methods: A cross-sectional study was conducted from January to July 2017. Patients attending two selected SerD facilities in the city of Naples, Italy were interviewed with a questionnaire gathering information on sociodemographic data, characteristics of drug addiction, characteristics of enrolment at the SerD, self-reported health status and wellness, and reports of the discrimination suffered. Results: Among the 451 people interviewed, 72.3% had started taking drugs by the age of 20, and half of them have used drugs within the last year. 54.5% of responders attended SerD for more than 10 years, and the two main reasons for attendance were to get help and to get methadone. 79.4% were declared to have a good/very good/excellent health status at the time of interviewing. 53.7% reported suffering from discrimination. Conclusions: Based on our study, discrimination is higher in participants who attended SerD for more than one year, who were formerly in prison, or who were current drug users.

Health Related Quality of Life in Individuals Transferred from a Needle Exchange Program and Starting Opioid Agonist Treatment

Background

Opioid agonist treatment (OAT), for the treatment of heroin dependence, has been reported to improve overall health and lower mortality. Drug use and retention in treatment have often been used as measures of treatment success. More recently, however, researchers have suggested that measurements of quality of life should be an outcome in substance use treatment evaluations. In a recent randomized controlled trial we demonstrated high rates of successful rapid referral from a needle exchange program (NEP) to OAT. The aim of this study was to see whether an improvement in health related quality of life (HRQoL) could be seen at 3-month follow-up after starting OAT and whether it was associated with any baseline characteristics. We also wanted to compare our sample to a sample from the general population with regard to HRQoL.

Methods

This was a 3-month follow-up of 71 patients who started OAT. Measurements of HRQoL with EQ-5D (an instrument developed by the EuroQol group) were made at baseline and at three months.

Results

Mean EQ-5D VAS (visual analogue scale) for the study sample at baseline was 47.3, which was lower than a Swedish reference population reporting 83.3. Individuals reporting being prescribed a drug for a psychiatric condition had significantly lower EQ-5D index values. Improvement in EQ-5D index score was significantly less for individuals reporting previous overdoses (-0.10, p=0.025). Individuals reporting previous suicide attempts had significantly lower EQ-5D VAS score at baseline. A significant increase of the EQ-5D VAS difference over time was found with a mean difference of 10.94 (p=0.008) for the total sample.

Conclusion

To our knowledge this is the first time HRQoL as an outcome is reported in a population transferred from a NEP to OAT. Our results indicate that OAT can result in increased HRQoL, even with this type of rapid low-threshold referral.

Safety and tolerability of sauna detoxification for the protracted withdrawal symptoms of substance abuse

Objective

Protracted drug withdrawal symptoms can last months or years after drug cessation, often precipitating a return to substance misuse. We evaluated the safety and preliminary health benefits of a unique chemical exposure regimen based on exercise, sauna and therapeutic nutrients.

Methods

This was a prospective evaluation of 109 individuals sequentially enrolled into a sauna detoxification component of a multi-modal, long-term residential substance abuse treatment centre.

Results

Data from medical charts, client self-reports and Short Form Health Survey (SF-36) responses indicated that the Hubbard sauna detoxification method was well tolerated, with a 99% completion rate, including one human immunodeficiency virus and nine hepatitis C positive clients. There were no cases of dehydration, overhydration or heat illness. Statistically significant improvements were seen in both mental and physical SF-36 scores at regimen completion, as well as in Addiction Severity Index and Global Appraisal of Individual Needs Short Screener change scores at rehabilitation program discharge, compared with enrolment.

Conclusions

The regimen lacked serious adverse events, had a very low discontinuation rate and high client-reported satisfaction. The SF-36 data indicated improved physical and emotional symptoms. Therefore, broader investigation of this sauna-based treatment regimen is warranted.

Decision-making, somatic markers and emotion processing in opiate users

RATIONALE

Opiate use is associated with deficits in decision-making. A possible explanation for these deficits is provided by the somatic marker hypothesis, which suggests that substance users may experience abnormal emotional responses during decision-making involving reward and punishment. This in turn may interfere with the brief physiological arousal, i.e. somatic markers that normally occur in anticipation of risky decisions. To date, the applicability of the somatic marker hypothesis to explain decision-making deficits has not been investigated in opiate users.

OBJECTIVES

This study assessed whether decision-making deficits in opiate users were related to abnormal emotional responses and reduced somatic markers.

METHODS

Opiate users enrolled in an opiate substitute treatment program (n = 28) and healthy controls (n = 32) completed the Iowa Gambling Task (IGT) while their skin conductance responses (SCRs) were recorded. Participants' emotional responses to emotion-eliciting videos were also recorded using SCRs and subjective ratings.

RESULTS

Opiate users displayed poorer decision-making on the IGT than did controls. However, there were no differences between the groups in SCRs; both groups displayed stronger SCRs following punishment than following reward, and both groups displayed stronger anticipatory SCRs prior to disadvantageous decisions than advantageous decisions. There were no group differences in objective or subjective measures of emotional responses to the videos.

CONCLUSIONS

The results suggest that deficits in emotional responsiveness are not apparent in opiate users who are receiving pharmacological treatment. Thus, the somatic marker hypothesis does not provide a good explanation for the decision-making deficits in this group.

Chronic pain and opioid abuse: Factors associated with health-related quality of life

BACKGROUND AND OBJECTIVES

While research on the separate relationships between health-related quality of life (HRQOL) and chronic pain, and HRQOL and opioid abuse has been sparse, even less work has investigated the factors associated with HRQOL in individuals who have both chronic pain and meet criteria for opioid use disorder. The data presented in this analysis should allow a better understanding the factors important to quality of life among this dual-diagnosed population.

METHODS

Individuals with dual diagnoses of chronic pain and opioid use disorder were recruited for clinical research studies at Columbia University Medical Center. Participants (n = 47) completed inventories to assess pain (Brief Pain Inventory), opioid (ab)use, and depression (Beck Depression Inventory). Variable from these and other inventories, along with demographic factors (age, race, sex, pain severity, depressive symptoms, duration of opioid use, route of opioid use, amount of opioid use) were entered into a regression analysis in order to identify the strongest predictors of SF-36 Health Survey score.

RESULTS

In the bivariate analysis we found that demographic and drug use variables were rarely associated with HRQOL. Typically, ratings of pain severity and pain interference were the best predictors. In the multivariate analysis, we found that across the several HRQOL dimensions greater Brief Pain Inventory (BPI) ratings of pain "interference" and Beck Depression Inventory (BDI) scores were consistently associated with lower HRQOL.

CONCLUSIONS AND SCIENTIFIC SIGNIFICANCE

These data suggest that insufficient pain management and depression are significant variables contributing to lower quality of life among individuals with chronic pain and opioid use disorder. (Am J Addict 2017;26:815-821).

Effects of a Randomized Comprehensive Psychosocial Intervention Based on Cognitive Behavioral Therapy Theory and Motivational Interviewing Techniques for Community Rehabilitation of Patients With Opioid Use Disorders in Shanghai, China

OBJECTIVES

China is faced with the challenge of community rehabilitation of persons with opioid use disorders. A 1-year comprehensive psychosocial intervention (CPI) was developed, and its effectiveness was assessed in terms of its ability to improve community rehabilitation of persons with opioid use disorders after their release from detention in compulsory treatment centers in Shanghai, China.

METHODS

Participants were randomized to the CPI (n = 90) condition or the usual community care (UCC, n = 90) as a control condition. The Addiction Severity Index, Symptom Checklist-90, and Medical Outcomes Study 36-Item Short Form Health Survey were administered at baseline and at the end of the intervention. Urine screens were used to increase the validity of self-reported drug use.

RESULTS

Compared with the UCC group at follow-up, the CPI group showed lower scores in 6 dimensions of the Symptom Checklist-90: somatization, obsessive-compulsive, anxiety, phobia-anxiety, paranoia, and psychoticism. Members of the CPI group had higher scores in 2 dimensions of the 36-Item Short Form Health Survey—physical role limitation and emotional role limitation—compared with the UCC group (P < 0.05). A logistic regression analysis revealed that phobia-anxiety, lifetime heroin or amphetamine use, and injection drug use were risk factors of relapse, but differences were not found in drug urine test or self-report drug use between the 2 groups (P > 0.05).

CONCLUSIONS

The CPI condition improved participants' mental health and quality of life, and it could be a promising community rehabilitation approach for patients with opioid use disorders in recovery.

Improvements in health-related quality of life among methadone maintenance clients in Dar es Salaam, Tanzania

BACKGROUND

Injection of heroin has become widespread in Dar es Salaam, Tanzania and is spreading throughout the country. To prevent potential bridging of HIV epidemics, the Tanzanian government established a methadone maintenance treatment (MMT) clinic in February 2011. We assess the effect of MMT on health-related quality of life (HRQOL) and examine factors, particularly HIV infection and methadone dose, associated with changes in HRQOL.

METHODS

This study utilized routine data on clients enrolling in methadone from February 2011 to April 2012 at Muhimbili National Hospital. Change in physical (PCS) and mental health (MCS) composite scores, as measured by the SF-12 tool, were the primary outcomes. Backward stepwise linear regression, with a criterion of p<0.2 was used to identify baseline exposure variables for inclusion in multivariable models, while adjusting for baseline scores.

RESULTS

A total of 288 MMT clients received baseline and follow-up assessments. Mean methadone dose administered was 45mg (SD±25) and 76 (27%) were confirmed HIV-positive. Significant improvements were observed in PCS and MCS, with mean increases of 15.7 and 3.3, respectively. In multivariable models, clients who had previous poly-substance use with cocaine [p=0.040] had a significantly higher mean change in PCS. Clients who were living with HIV [p=0.002]; satisfied with current marital situation [p=0.045]; had a history of suicidal thoughts [p=0.021]; and previously experienced cognitive difficulties [p=0.012] had significantly lower mean change in PCS. Clients with shorter history of heroin use [p=0.012] and who received higher methadone doses [p=0.028] had significantly higher mean change in MCS, compared to their counterparts.

CONCLUSION

Aspects of mental and physical health, risk behaviors and quality of life among drug users are intertwined and complex. Our research revealed positive short-term effects of MMT on HRQOL and highlights the importance of sustained retention for optimal benefits. Comprehensive supportive services in addition to provision of methadone are needed to address the complex health needs of people who inject drugs.

Cross-sectional study of the severity of self-reported depressive symptoms in heroin users who participate in a methadone maintenance treatment program

Background

Methadone maintenance treatment (MMT) is widely recognized as an effective method of combatting narcotic addiction. MMT reduces heroin withdrawal symptoms and, thus, makes it possible to provide the psychological and social support that is essential to the rehabilitation of drug users.

Aim

Compare the severity of depressive symptoms in heroin users who are currently receiving MMT to that of heroin users who are not receiving MMT.

Methods

We administered the 13-item version of the Beck Depression Inventory (BDI-13) and a demographic history form to 929 heroin users who had been receiving MMT at nine methadone treatment clinics in three Chinese cities for an average of 9 months and to 238 heroin users who had enrolled in a MMT program at the centers but had not yet begun MMT.

Results

Seventy-nine percent (188/238) of the untreated individuals reported depressive symptoms compared to 68% (628/929) of the individuals receiving MMT (χ²=11.69, p<0.001). The median (interquartile range) BDI score in the untreated group was 10.4 (7.9-11.4) compared to 8.0 (5.7-11.6) in the MMT group (Z=2.75, p=0.006). In the MMT group, there was a negative correlation between the severity of reported depressive symptoms and the duration of participation in the MMT program (r_s=-0.24, Z=2.88, p=0.004). Multivariate linear regression analysis showed that after adjusting for all demographic variables the treated group still had less severe depressive symptoms than the untreated group. After adjusting for the effect of MMT treatment, depressive symptoms were more severe in heroin users who self-reported poor family relationships (standardized regression coefficient β=0.118, t=6.56, p<0.001) and in those who were divorced (β=0.120, t=3.73, p<0.001).

Conclusions

Moderate to severe depressive symptoms are common in heroin users. MMT is associated with lower levels of depressive symptoms in heroin users, but prospective randomized controlled trials are needed to determine whether or not MMT actually improves depressive symptoms in heroin users. Poor relationships with family members are also associated with depressive symptoms in heroin users; this suggests that treatment of heroin addiction needs to incorporate methods for helping heroin users repair the severed social relationships that their addiction has caused.

Health-related quality of life among prescription opioid-dependent patients: Results from a multi-site study

BACKGROUND

Although prescription opioid use disorder has recently increased sharply in the United States, relatively little is known about the general well-being of this population. Assessment of quality of life in patients with substance use disorders has been recommended to improve clinical care.

OBJECTIVES

Health-related quality of life was examined in prescription opioid-dependent patients at entry to a national multi-site clinical trial, to compare quality of life scores in the study sample to other populations; further, background variables associated with quality of life in the literature were examined.

METHODS

Prescription opioid-dependent patients (N = 653) were compared to general populations on the Medical Outcome Study Short Form-36 (SF-36) quality of life measure; and the association between patient background variables and quality of life was examined.

RESULTS

Compared to a general population, the current sample of prescription opioid-dependent patients had worse physical (-1.7 points, p < .001) and mental quality of life (-12.3 points, p < .001) as measured by the SF-36, similar to other opioid-use disorder populations. Within our sample, women showed more impairment than men in mental quality of life (-4.3 points, p < .001); older patients scored worse on physical (-5.2 points, p < .001), but not mental, quality of life. Chronic pain was associated with poorer physical quality of life (-9.0 points, p < .001).

CONCLUSIONS AND SCIENTIFIC SIGNIFICANCE

The growing focus on wellness underscores the importance of measuring quality of life in addition to substance use outcomes. Routine assessment of health-related quality of life can add an important dimension to overall evaluation of patients' treatment response.

Changes in quality of life (WHOQOL-BREF) and addiction severity index (ASI) among participants in opioid substitution treatment (OST) in low and middle income countries: an international systematic review

BACKGROUND

Opioid substitution treatment (OST) can increase quality of life (WHOQOL-BREF) and reduce addiction severity index (ASI) scores among participants over time. OST program participants have noted that improvement in quality of life is one of the most important variables to their reduction in drug use. However, there is little systematic understanding of WHOQOL-BREF and ASI domain changes among OST participants in low and middle-income countries (LMIC).

METHODS

Utilizing PRISMA guidelines we conducted a systematic literature search to identify OST program studies documenting changes in WHOQOL-BREF or ASI domains for participants in buprenorphine or methadone programs in LMIC. Standardized mean differences for baseline and follow-up domain scores were compared along with relationships between domain scores, OST dosage, and length of follow-up.

RESULTS

There were 13 OST program studies with 1801 participants from five countries eligible for inclusion in the review. Overall, statistically significant changes were noted in all four WHOQOL-BREF domain and four of the seven ASI domain scores (drug, psychological, legal, and family) documented in studies. Dosage of pharmacologic medication and length of follow-up did not affect changes in domain scores.

CONCLUSION

WHOQOL-BREF and ASI domain scoring is a useful tool in measuring overall quality of life and levels of addiction among OST participants. Coupled with measurements of blood-borne infection, drug use, relapse, and overdose, WHOQOL-BREF and ASI represent equally important tools for evaluating the effects of OST over time and should be further developed as integrated tools in the evaluation of participants in LMIC.

Days of heroin use predict poor self-reported health in hospitalized heroin users

This study examined associations between substance use behaviors and self-reported health among hospitalized heroin users. Of the 112 participants, 53 (47%) reported good or better health. In multivariable logistic regression models, each day of heroin use in the last month was associated with an 8% lower odds of reporting health as good or better (OR=.92; 95% CI 0.87, 0.97, p<.05). Cocaine, cannabis, cigarettes, alcohol use, unintentional overdose, nor injection drug use was associated with health status.

Psychometrics of the Short Form 36 Health Survey version 2 (SF-36v2) and the Quality of Life Scale for Drug Addicts (QOL-DAv2.0) in Chinese mainland patients with methadone maintenance treatment

OBJECTIVE

To test psychometrics of the Short Form 36 Health Survey version 2 (SF-36v2) and the Quality of Life Scale for Drug Addicts (QOL-DAv2.0) in Chinese mainland patients with methadone maintenance treatment (MMT).

METHODS

A total of 1,212 patients were recruited from two MMT clinics in Xi'an, China. Reliability was estimated with Cronbach's α and intra-class correlation (ICC). Convergent and discriminant validity was assessed using multitrait-multimethod correlation matrix. Sensitivity was measured with ANOVA and relative efficiency. Responsiveness was evaluated by pre-post paired-samples t-test and standardized response mean based on the patients' health status changes following 6-month period.

RESULTS

Cronbach's α of the SF-36v2 physical and mental summary components were 0.80 and 0.86 (eight scales range 0.73-0.92) and the QOL-DAv2.0 was 0.96 (four scales range: 0.80-0.93). ICC of the SF-36v2 two components were 0.86 and 0.85 (eight scales range: 0.72-0.87) and the QOL-DAv2.0 was 0.94 (four scales range: 0.88-0.92). Convergent validity was lower between the two instruments (γ <0.70) while discriminant validity was acceptable within each instrument. Sensitivity was satisfied in self-evaluated health status (both instruments) and average daily methadone dose (SF-36v2 physical functioning and vitality scales; QOL-DAv2.0 except psychology scale). Responsiveness was acceptable in the improved health status change (SF-36v2 except vitality scale; QOL-DAv2.0 except psychology and symptoms scales) and deteriorated health status change (SF-36v2 except vitality, social functioning and mental health scales; QOL-DAv2.0 except society scale).

CONCLUSIONS

The SF-36v2 and the QOL-DAv2.0 are valid tools and can be used independently or complementary according to different emphases of health-related quality of life evaluation in patients with MMT.

Occurrence and characteristics of chronic pain in a community-based cohort of indigent adults living with HIV infection

Pain is common among people living with HIV/AIDS (PLWHA), but little is known about chronic pain in socioeconomically disadvantaged HIV-infected populations with high rates of substance abuse in the postantiretroviral era. This cross-sectional study describes the occurrence and characteristics of pain in a community-based cohort of 296 indigent PLWHA. Participants completed questionnaires about sociodemographics, substance use, depression, and pain. Cut-point analysis was used to generate categories of pain severity. Of the 270 participants who reported pain or the use of a pain medication in the past week, 8.2% had mild pain, 38.1% had moderate pain, and 53.7% had severe pain. Female sex and less education were associated with more severe pain. Depression was more common among participants with severe pain than among those with mild pain. Increasing pain severity was associated with daily pain and with chronic pain. Over half of the participants reported having a prescription for an opioid analgesic. Findings from this study suggest that chronic pain is a significant problem in this high risk, socioeconomically disadvantaged group of patients with HIV disease and high rates of previous or concurrent use of illicit drugs.

PERSPECTIVE

This article presents epidemiological data showing that unrelieved chronic pain is a significant problem for indigent people living with HIV. Participants reported pain severity similar to those with metastatic cancer. Despite high rates of substance use disorders, approximately half received prescriptions for opioid analgesics, although few for long-acting agents.

Gender differences in physical and mental health outcomes among an aging cohort of individuals with a history of heroin dependence

BACKGROUND

This paper examines the health status and functioning of an aging cohort of individuals with a history of heroin dependence with a focus on gender differences.

METHOD

Study subjects were originally sampled from methadone maintenance clinics in California in the 1970s and completed follow-up interviews in 2005-09. Out of the original study sample (N=914), 343 participants (44.3% female) were interviewed (70.6% of those not deceased). Bivariate analyses examined gender differences in participants' overall health status and physical and mental health problems. Scores on SF-36 scales were compared with general population norms by gender and age, as well as between participants in the study sample who did and did not report past-year drug use.

RESULTS

Average age of the study sample was 58.3 (SD=4.9) years for males and 55.0 (SD=4.1) years for females. There were no significant gender differences in past-year drug use (38% of sample) or injection drug use (19%). Women reported significantly more chronic health problems and psychological distress compared with men, and overall poorer health and functioning compared with general population norms. Men under 65 had poorer physical health and social functioning compared with population norms. Men in the study sample reporting past-year substance use had poorer physical functioning, but less bodily pain, than non-users, whereas women with past-year substance use had poorer mental health than other women.

CONCLUSION

Individuals with a history of heroin dependence have poorer health and functioning than their counterparts in the general population. At a younger age, women reported poorer overall health status and more chronic health and mental health problems than men. Study findings may inform interventions for this population, particularly related to gender-specific treatment needs.

Clinical correlates of health-related quality of life among opioid-dependent patients

PURPOSE

Previous work suggests that opioid users have lower health-related quality of life (HRQOL) than patients with more prevalent chronic illnesses such as hypertension or diabetes. Although comparisons with population norms are informative, studies of the correlates of HRQOL for opioid users are needed to plan clinical services.

METHODS

We tested a conceptual model of the pathways between physiologic factors and symptoms in relation to HRQOL among 344 opioid users in a clinical trial. Physical and mental HRQOL were measured by the Short-Form (SF)-36; withdrawal signs, symptoms, and functioning were also measured with validated instruments. Using structural equation modeling, we tested hypotheses that medical history directly predicts withdrawal signs and symptoms, and that medical history, withdrawal signs and symptoms, and functioning predict the physical and mental HRQOL latent variables of the SF-36.

RESULTS

Most hypothesized relationships were significant, and model fit was good. The model explained 36% of the variance in mental HRQOL and 34% of the variance in physical HRQOL.

CONCLUSIONS

The conceptual framework appears valid for explaining variation in the physical and mental HRQOL of opioid users undergoing medically managed withdrawal. Analysis of longitudinal data would help to evaluate more rigorously the adequacy of the model for explaining HRQOL in opioid withdrawal.

Gender differences in health related quality of life of young heroin users

BACKGROUND

Health Related Quality of Life (HRQL) of opiate users has been studied in treatment settings, where assistance for drug use was sought. In this study we ascertain factors related to HRQL of young opiate users recruited outside treatment facilities, considering both genders separately.

METHODS

Current opiate users (18-30 y) were recruited in outdoor settings in three Spanish cities (Barcelona, Madrid, Seville). Standardised laptop interviews included socio-demographic data, drug use patterns, health related issues, the Severity of Dependence Scale (SDS) and the Nottingham Health Profile (NHP).

RESULTS

A total of 991 subjects (73% males), mean age = 25.7 years were interviewed. The mean global NHP score differed by gender (women: 41.2 (sd:23.8); men:34.1(sd:23.6);p < 0.05). Multivariate analysis was implemented separately by gender, variables independently related with global NHP score, both for males and females, were heroin and cocaine SDS scores. For women, only other drug related variables (alcohol intake and length of cocaine use) were independently associated with their HRQL. HIV+ males who suffered an opiate overdose or had psychiatric care in the last 12 months perceived their health as poorer, while those who had ever been in methadone treatment in the last 12 months perceived it as better. The model with both genders showed all factors for males plus quantity of alcohol and an interaction between gender and HIV status.

CONCLUSIONS

Heroin users were found to be at a considerable risk of impaired HRQL, even in these young ages. A score approaching severity of dependence was the factor with the strongest relation with it.

Current quality of life and its determinants among opiate-dependent individuals five years after starting methadone treatment

Purpose

This study explores the current QoL of opiate-dependent individuals who started outpatient methadone treatment at least 5 years ago and assesses the influence of demographic, psychosocial, drug and health-related variables on individuals’ QoL.

Methods

Participants (n = 159) were interviewed about their current QoL, psychological distress and severity of drug-related problems, using the Lancashire Quality of Life Profile, the Brief Symptom Inventory and the Addiction Severity Index. Potential determinants of QoL were assessed in a multiple linear regression analysis.

Results

Five years after the start of methadone treatment, opiate-dependent individuals report low QoL scores on various domains. No association was found between drug-related variables and QoL, but a significant negative impact of psychological distress was identified. Severity of psychological distress, taking medication for psychological problems and the inability to change one’s living situation were associated with lower QoL. Having at least one good friend and a structured daily activity had a significant, positive impact on QoL.

Conclusions

Opiate-dependent individuals’ QoL is mainly determined by their psychological well-being and a number of psychosocial variables. These findings highlight the importance of a holistic approach to treatment and support in methadone maintenance treatment, which goes beyond fixing the negative physical consequences of opiate dependence.

Clinical Characteristics of Central European and North American Samples of Pregnant Women Screened for Opioid Agonist Treatment

BACKGROUND

Little comparable information is available regarding clinical characteristics of opioid-dependent women from different countries. In the present study, women from the USA, Canada and a Central European country, Austria, screened for participation in the Maternal Opioid Treatment Human Experimental Research study, were compared with respect to their demographic and addiction histories.

METHODS

Pregnant women (n = 1,074) were screened for study participation using uniformed clinical criteria and instruments. The screening results were compared with regard to exclusion, demographics, drug use, and psychosocial and treatment histories.

RESULTS

Compared to the screened US and Canadian women, Austrian women were more likely to be younger (p < 0.001), white (p < 0.001), had significantly lower levels of educational attainment (p < 0.001), were less likely to use opioids daily (p < 0.001) and more likely to have been prescribed buprenorphine (p < 0.001). Compared to both rural and urban US groups, the Austrian group was less likely to have legal issues (p < 0.001) and was younger when first prescribed agonist medication (p < 0.001).

CONCLUSION

The differences between North American and European groups may offer unique insights concerning treatment and pregnancy outcomes for opioid-dependent pregnant women.

Gender differences among regular injecting drug users in Sydney, Australia, 1996-2003

Previous research has found that female injecting drug users (IDU) are younger and more likely to be involved in risky behaviours such as needle sharing and sex work than male IDU. Aboriginal female drug users, in particular, are over-represented in IDU and prison populations. These factors place female IDU at increased risk of health problems and complicate issues such as homelessness, unemployment and poverty. Although a substantial body of research exists, little trend analysis has been done in Australia and much of the previous literature has focused on treatment populations. Cross-sectional data from 1996 to 2003 from regular IDU in Sydney interviewed as part of Australia's drug monitoring system, the Illicit Drug Reporting System (IDRS) were examined for trends over time. The demographic characteristics, drug use patterns and self-reported risk behaviours of the most recent sample (2003) were analysed for gender differences. Female IDU were younger in all sample years. Female IDU were more likely to identify as Aboriginal or Torres Strait Islander (ATSI) and engage in sex work. There has been a steady increase in these proportions over time. Female IDU were less likely to have a prison history, although there has been an increase among both male and female IDU over time. There were no gender differences in drug use patterns or frequency of drug use. Larger proportions of females report lending needles. Reports of lending and borrowing needles have decreased over time among both male and female IDU. Female IDU may place themselves at greater risk than male IDU by being more likely to share injecting equipment and engage in sex work. Treatment and other measures to reduce harm may need to be targeted specifically at women and, in particular, indigenous women.

Women injecting drug users in London: the extent and nature of their contact with drug and health services

Improved access to drug treatment and other health services remains central to HIV prevention and other harm reduction strategies among injecting drug users (IDUs) in the UK. Efforts have therefore been focused upon making such services more accessible and 'user friendly'. Women who use drugs are considered a 'hard to reach' population. This is largely based on data from a variety of official sources which have suggested that women are under-represented as clients of drug services. While current literature provides numerous explanations for this, there have been few empirical studies exploring the nature and extent of women's contact with such services. This paper presents findings from an European Community funded survey of women IDUs in London. Data from this survey suggest that women IDUs have surprisingly high levels of contact with a range of specialist and generic health services in relation to their drug use.

Health and well-being outcomes for drug-dependent offenders on the NSW Drug Court programme

Given the centrality of drug treatment to the drug court framework, the proliferation of drug courts in the United States, and their emergence more recently in Australia, it is surprising that such little attention has been given to assessing their therapeutic effect. This evaluation aimed to assess the health and well-being of drug-dependent offenders diverted to the New South Wales Drug Court, and monitor changes in their health and well-being throughout 12 months of programme participation. The study consisted of baseline interviews with 202 offenders accepted into the programme between February 1999 and April 2000, and follow-up interview at 4, 8 and 12 months with participants who remained on the programme. Health and well-being was assessed at each follow-up using the Short Form-36 Health Survey (SF-36) the OTI social functioning scale, and self-reported spending as a proxy for illicit drug use. The health of male Drug Court participants prior to commencing the programme was significantly poorer than Australian population norms. The results provided evidence of significant and sustained improvements in health and well-being for the 51 participants who competed each follow-up interview. Furthermore, significant improvements were found for offenders who remained on the programme for at least 4 months but less than 12 months. However, the positive health outcomes are limited by the low programme retention rate. These results indicate that significant health outcomes can be achieved for at least some heavily drug-dependent, recidivist offenders through the drug court model. [Freeman K.

Changes and predictors of change in the physical health status of heroin users over 24 months

AIMS

(i) To describe the course of physical health among the ATOS cohort over 24 months; and (ii) to examine the effects of treatment, drug use patterns and social and psychological factors on health status over 24 months.

DESIGN

Longitudinal cohort.

SETTING

Sydney, Australia.

PARTICIPANTS

A total of 615 heroin users recruited for the Australian Treatment Outcome Study (ATOS).

FINDINGS

The general health of the cohort improved significantly over 24 months. Significant predictors of poor health over 24 months were: being older, being female, past month heroin, other opiate and tobacco use, past month unemployment and current major depression. Spending a greater proportion of time in residential rehabilitation (RR) was associated with better health over 24 months. No other treatment factors demonstrated a significant, independent relationship with health.

CONCLUSIONS

The physical health of dependent heroin users is affected by drug use and psychosocial problems. RR treatment appears to be particularly beneficial to the health of heroin users, suggesting the importance of a comprehensive approach to improving health among this group.

Injection Drug User Quality of Life Scale (IDUQOL): findings from a content validation study

Background

Quality of life studies among injection drug users have primarily focused on health-related measures. The chaotic life-style of many injection drug users (IDUs), however, extends far beyond their health, and impacts upon social relationships, employment opportunities, housing, and day to day survival. Most current quality of life instruments do not capture the realities of people living with addictions. The Injection Drug Users' Quality of Life Scale (IDUQOL) was developed to reflect the life areas of relevance to IDUs. The present study examined the content validity of the IDUQOL using judgmental methods based on subject matter experts' (SMEs) ratings of various elements of this measure (e.g., appropriateness of life areas or items, names and descriptions of life areas, instructions for administration and scoring).

Methods

Six SMEs were provided with a copy of the IDUQOL and its administration and scoring manual and a detailed content validation questionnaire. Two commonly used judgmental measures of inter-rater agreement, the Content Validity Index (CVI) and the Average Deviation Mean Index (AD_M), were used to evaluate SMEs' agreement on ratings of IDUQOL elements.

Results

A total of 75 elements of the IDUQOL were examined. The CVI results showed that all elements were endorsed by the required number of SMEs or more. The AD_M results showed that acceptable agreement (i.e., practical significance) was obtained for all elements but statistically significant agreement was missed for nine elements. For these elements, SMEs' feedback was examined for ways to improve the elements. Open-ended feedback also provided suggestions for other revisions to the IDUQOL.

Conclusion

The results of the study provided strong evidence in support of the content validity of the IDUQOL and direction for the revision of some IDUQOL elements.

The impact of illicit drug use and harmful drinking on quality of life among injection drug users at high risk for hepatitis C infection

BACKGROUND

Heavy alcohol use, hepatitis C and illicit drug use each have been shown to have negative impacts on health-related quality of life (HRQL). To date, considerations of HRQL have not played a prominent role in the design and measurement of intervention strategies for out-of-treatment at-risk populations.

METHODS

Data were collected from out-of-treatment IDUs recruited through street outreach in North Carolina. Multiple linear regression analyses were used to examine the independent effects of HCV status, harmful drinking (AUDIT), and illicit drug use on HRQL (SF-36).

RESULTS

Fifty-one percent of 619 study participants tested HCV-positive; 57% met criteria for harmful or hazardous drinking and 63% reported daily use of hard drugs. HRQL scores for this population were significantly lower than those of the general population. Multiple linear regression analyses demonstrated that harmful levels of alcohol consumption and use of methamphetamine in the past month had the strongest associations with reduced HRQL.

CONCLUSIONS

Given the high rates of HCV in most IDU communities, new harm reduction approaches are needed for these populations which focus beyond prevention to the functioning and well being of those already infected. In particular, reducing heavy alcohol use in addition to slowing HCV progression shows promise for improving HRQL.

Healthcare utilization of individuals with opiate use disorders: an analysis of integrated medicaid and state mental health/substance abuse agency data

Data from the Substance Abuse and Mental Health Services Administration’s Integrated Database (IDB) were used to examine the service use patterns of individuals with possible opiate use disorders in Washington State. Results indicate that regardless of Medicaid enrollment status, individuals who received mental health (MH) or substance abuse (SA) services only through state agencies received no inpatient substance abuse service. Furthermore, when compared with individuals who received at least one MH/SA service through Medicaid, those who received services only through the state agencies were less likely to have received any MH services and were more likely to have received residential SA services. This analysis highlights the importance of using integrated client data in providing a more comprehensive understanding of services to inform policy and raises significant questions about how regulatory requirements affecting different funding mechanisms might drive settings of care in ways not related to the care needed.

Determinants of health-related quality of life of opiate users at entry to low-threshold methadone programs

OBJECTIVE

The aim of this study was to conduct an exploratory analysis of factors associated with poor health-related quality of life (HRQOL) among opiate users at entry to low-threshold methadone treatment.

METHODS

The SF-36 questionnaire was administered to 145 opiate users at enrollment into low-threshold methadone maintenance programs. ANOVA and correlational analyses were performed to investigate the determinants of poor physical and mental composite summary scales (PCS and MCS) of the SF-36 among opiate users. Stepwise regression methods were also employed to fit PCS and MCS multivariate models.

RESULTS

Age, employment status, chronic medical conditions, hospitalization, emotional abuse, sexual abuse and age at first injection episode were significantly associated with PCS. Mental health problems, sexual abuse, physical abuse, the use of sedatives, the use of cocaine, the number of days of cocaine use, sedative use and multiple substance use in the past month were significantly associated with MCS. The variances in the MCS and PCS were not readily explained by any one factor.

CONCLUSION

The multiplicity of factors influencing HRQOL of opiate users suggests the need for a range of services within the context of a methadone program, addressing primary medical care needs as well as treatment for both mental health problems and abuse issues.

Health problems and help-seeking activities of methadone maintenance clients at Auckland Methadone Service (AMS): potential for community pharmacy service expansion?

Background

In general the health of methadone clients has been found to be poorer than that of the general population. In New Zealand specialist drug services are not funded to provide primary healthcare services. Many health conditions could potentially be managed by community pharmacists who have frequent contact with this client group. This study sought to explore the health problems suffered by methadone clients, who they sought help from, and the potential for greater involvement of pharmacists.

Methods

Self-completion questionnaire of methadone maintenance clients managed in specialist care in Auckland, New Zealand.

Results

The most common health problem experienced by these clients in the past three months was sweating (70.0%), and more than half of the respondents also reported experiencing headache, fatigue and depression. The least frequently experienced conditions were hay fever (12.9%) and abscesses (12.1%). Respondents indicated that the top three choices from whom they would seek help were GP (56.7%), the client's partner (31.6%) and community pharmacists (27.9%). Barriers to seeking help from pharmacists included issues around cost, perceptions of pharmacist knowledge and skills, privacy and confidentiality.

Conclusion

Methadone clients in this study indicated that they suffered a number of general health problems, and in many cases were likely to seek help from a GP or their own partner, before seeking help from pharmacists. However, for over one quarter of respondents the pharmacist was in the top three from whom they would seek advice. Any barriers towards consulting pharmacists, in the main seem to be resolvable.

Injection Drug Use Quality of Life scale (IDUQOL): a validation study

BACKGROUND

Existing measures of injection drug users' quality of life have focused primarily on health and health-related factors. Clearly, however, quality of life among injection drug users is impacted by a range of unique cultural, socioeconomic, medical, and geographic factors that must also be considered in any measure. The Injection Drug User Quality of Life (IDUQOL) scale was designed to capture the unique and individual circumstances that determine quality of life among injection drug users. The overall purpose of the present study was to examine the validity of inferences made from the IDUQOL by examining the (a) dimensionality, (b) reliability of scores, (c) criterion-related validity evidence, and (d) both convergent and discriminant validity evidence.

METHODS

An exploratory factor analysis using principal axis factoring in SPSS 12.0 was conducted to determine whether the use of a total score on the IDUQOL was advisable. Reliability of scores from the IDUQOL was obtained using internal consistency and one-week test-retest reliability estimates. Criterion-related validity evidence was gathered using variables such as stability of housing, sex trade involvement, high-risk injection behaviours, involvement in treatment programs, emergency treatment or overdose over the previous six months, hospitalization and emergency treatment over the subsequent six month period post data collection. Convergent and discriminant validity evidence was gathered using measures of life satisfaction, self-esteem, and social desirability.

RESULTS

The sample consisted of 241 injection drug users ranging in age from 19 to 61 years. Factor analysis supports the use of a total score. Both internal consistency (alpha = .88) and one-week test-retest reliability (r = .78) for IDUQOL total scores were good. Criterion-related, convergent, and discriminant validity evidence supports the interpretation of IDUQOL total scores as measuring a construct consistent with quality of life.

CONCLUSION

The findings from this study provide initial evidence to support the use of the IDUQOL total score. The results of the study also suggest the IDUQOL could be further strengthened with additional attention to how some IDUQOL domains are described and satisfaction is measured.

Initiation to heroin injecting among heroin users in Sydney, Australia: cross sectional survey

BACKGROUND: Heroin injection is associated with health and social problems including hepatitis C virus (HCV) transmission. Few studies have examined the circumstances surrounding initiation to heroin injecting, especially current users initiating others. The current study aimed to examine the age of first heroin use and injection; administration route of first heroin use; relationship to initiator; the initiation of others among a group of heroin users; and to examine these factors in relation to HCV status and risk. METHOD: Heroin users in Sydney were recruited through needle and syringe programs, a methadone clinic and snowballing. Participants were interviewed about their own initiation to heroin use, blood-borne virus risk and knowledge, and whether they had initiated others to heroin injecting. Information on HCV status was collected via self-report. Data was analysed using univariate and multivariate statistical techniques for Normally distributed continuous and categorical data. RESULTS: The study recruited 399 heroin users, with a mean age of 31 years, 63% were male, 77% reported heroin as their primary drug and 59% were HCV positive (self-report). Mean age at first heroin use and injection was 19 and 21 years, respectively. The majority of heroin users commenced heroin use via injecting (65%), younger users (<25 years, 25-30 years) were less likely than older users (>30 years) to commence heroin use parenterally. Participants were initiated to injection mainly by friends (63%). Thirty-seven percent reported initiating others to heroin injection, but few factors were related to this behaviour. Those with longer heroin using careers were more likely to report initiating others to heroin injection, but were no more likely to have done so in the preceding 12 months. Participants who had initiated others were more likely to have shared injecting equipment (12 vs 23%), but were no more likely to be HCV positive (self-report) than those who did not. CONCLUSION: Interventions to prevent heroin users initiating others to injecting are necessary. Peer groups may be well positioned to implement such interventions.

Gender differences in health-related quality of life on admission to a maintenance treatment program

We compared the gender differences in health-related quality of life (QOL) on admission to a maintenance program. 103 opioid users (65 men and 38 women) admitted to a maintenance treatment program during 2000-2002 were studied. During this period we assessed the QOL status using the German version ('Berlin Quality of Life Profile') of the Lancashire Quality of Life Profile. Physical symptoms were measured using the Opioid Withdrawal Scale. 312 urine screening tests were carried out to evaluate consumption. The female group showed significantly less additional consumption of other opiates (p = 0.043) compared with the male group. The male group showed significantly better QOL scores in self-esteem (p = 0.015), psychical health (p = 0.027), and law and security (p = 0.008). The outcome measures for withdrawal scores showed significantly less symptoms for males in twitching of muscles (p = 0.034), vomiting (p = 0.002), depressions (p = 0.004) and poor appetite (p = 0.008). In summary, both genders showed only a few significant differences on admission in terms of QOL and physical symptoms. The predominant effects of drug use appear to eclipse the gender-related role pattern. Further exploration of gender and QOL could have important theoretical and treatment implications.

Dual diagnosis and quality of life in patients in treatment for opioid dependence

This study examined the relationship between quality of life (QOL) and dual diagnosis among patients in treatment for opioid dependence. The study sample includes 57 patients with opioid dependence alone (OD) and 41 with opioid dependence and a psychiatric axis-I disorder (DD), recruited in 2001 and 2004 at the Drug Addiction Services (SerT) of Bolzano and Pontedera (Italy). Participants were 73.5% males, with a mean age of 35.1 years (SD = 8.0). A comparison group of 45 healthy controls was also included. Assessments included a structured psychiatric interview (SCID) and a self-report quality of life assessment (WHOQOL-BREF). Patients with DD reported significantly (p < 0.05) poorer QOL in the physical and psychological domains as compared with patients with OD. Both groups of patients with and without DD showed significantly (p < 0.001) poorer QOL in the physical, psychological, and social domains with respect to healthy participants. The scores on the "relationship with environment" domain did not differ among OD, DD, and controls. The present study provides preliminary evidence that dual diagnosis is associated with poorer QOL and emphasizes the need to target treatment for the mental disorder concomitantly with the dependence problem in patients in treatment for opioid dependence.

Health status of clients receiving methadone maintenance treatment using the SF-36 health survey questionnaire

This study investigated the health status of a representative sample of clients (35 Maori, 72 non-Maori) receiving methadone maintenance treatment in New Zealand, using the SF-36 health survey. The publication of New Zealand norms in 1999 enabled comparisons of the health of the Methadone Treatment Programme study participants with that of the New Zealand population. Although over 50% of participants rated their health as good, very good or excellent, 44% rated their health as fair or poor and compared with population norms, the health of the study participants was significantly poorer on all eight SF-36 scales. Male and female participants rated their health similarly to male and female clients attending another New Zealand Methadone Treatment Programme. Results highlighted the impact of a chronic disorder and co-existing health-related problems on the health and well-being and day-to-day functioning of this client group. Higher frequency of benzodiazepine use was associated with poorer social functioning, mental health and role functioning and higher frequency of cannabis use was associated with poorer role functioning due to emotional problems. Findings support routine monitoring of health status with clients receiving methadone maintenance treatment as a guide to preventative and treatment interventions and health maintenance strategies.

Characteristics of heroin addicts entering methadone maintenance treatment: quality of life and gender

STUDY OBJECTIVE

To provide information on MMP patient's characteristics, particularly those related with Health Related Quality of Life (HRQoL) and gender.

DESIGN

Cross-sectional study. Data were collected on socio-demographic, toxicological variables, HIV risk behaviors, and HRQoL through the Nottingham Health Profile (NHP).

PATIENTS AND SETTING

Over a 30-month period (1996--1999) Barcelona's Municipal Drug Care Centres recruited 586 patients.

MAIN RESULTS

Mean age of patients was 31 years, 70% were males and 25% were HIV-infected. Rates of unemployment, criminal records and low educational level were high. Most poly-drug users used cocaine. NHP mean score was related with poly-drug use, educational level and HIV status. Consistent condom use was related with HIV status. Females' route of administration was less likely to be injection, even though they were more frequently HIV-positive and manifested contemporary poorer general health.

CONCLUSIONS

Patients QoL was poor. Nowadays harm reduction health strategies would need to face cocaine use, and sexual risk behaviors mainly among females and sexual partners.

Self-perceived health among Canadian opiate users: a comparison to the general population and to other chronic disease populations

BACKGROUND

There are an estimated 40,000 to 90,000 injection opiate users in Canada. The social, economic and health consequences of opiate addiction have been well documented. However, there are no data on the self-perceived health status of opiate users in Canada. Therefore, the goal of this research is to gain an understanding of the self-perceived health status of opiate users by comparing the health-related quality of life of opiate users to chronic disease populations and to the general population.

METHODS

The SF-36 was administered to a nonrandom sample of 143 opiate users entering low-threshold methadone treatment. Two sample t-tests were performed to assess statistical differences, at a 5% level of significance, between population scores across SF-36 dimensions.

RESULTS

Opiate users perceived both their mental and physical health as worse than the general population and individuals with minor and serious medical problems, but comparable to those with diagnosed psychiatric illnesses.

CONCLUSIONS

Methadone treatment services should incorporate both primary care and psychiatric care into their programs, or at the very least secure appropriate referral mechanisms to ancillary services to ensure that the health concerns of opiate users are dealt with in the context of their treatment program.

Measuring the health of Scottish drug users

Information on how individuals perceive their own health is important for providing appropriate health-related support and monitoring health over time. The Short Form 36 (SF-36) Health Status Questionnaire is one of the most widely used generic measures of self-perceived health status. Despite this, there has been no large-scale research documenting the SF-36 scores of problem drug users in the UK. The present paper has two aims: (1) to compare the self-perceived health of a sample of problem drug users with that of a sample from the general population; and (2) to investigate differences between the self-perceived health of various subgroups of problem drug users. In total, 1179 individuals starting a new episode of drug misuse treatment in Scotland were invited to complete a structured questionnaire that included the SF-36. Out of these, 1033 (87.6%) agreed and 990 successfully completed all SF-36 questions. The 990 completers were more likely than the 43 partial completers to be male [odds ratio (OR) = 0.45; 95% confidence interval (95% CI) = 0.24-0.85) and not in prison (OR = 0.36; 95% CI = 0.19-0.68). The reliability of the SF-36--measured by internal consistency--was very good (Cronbach's alpha > 0.7 for all eight dimensions). Comparing the respondents' mean dimension scores with those of a sample from the UK general population revealed that the drug users' health was consistently worse than that of the general population (> 20 points on seven out of the eight scales). Differences between the mean SF-36 scores of various subcategories of respondents were analysed using t-tests or an analysis of variance, as appropriate. The factors considered were: sex; age; imprisonment; relationship status; homelessness; and recent drug injection. Significant differences between particular groups of respondents were identified. Despite limitations with the data presented, the paper highlights the utility of the SF36 for drug misuse treatment providers.

Depression and drug use impact health status among marginally housed HIV-infected individuals

A representative sample of HIV-positive homeless and marginally housed individuals completed SF-36 health surveys and responses were analyzed for associations with sociodemographic, health, health care, and drug use variables. Among 330 respondents, 83% were male, 43% were African American, and the median age was 39 years. Negative associations were found between female gender and vitality as well as physical functioning; older age and physical functioning; drug use or drug treatment and role-emotional, social functioning, body pain, as well as vitality; health care utilization and depression with all scales. It appeared that depression and drug-related variables were associated with multiple dimensions of health status in this population. Interventions to treat depression and addiction may improve the health status of HIV-infected HMH.

Towards more effective public health programming for injection drug users: development and evaluation of the injection drug user quality of life scale

The psychometric properties of the Injection Drug User Quality of Life Scale (IDUQOL) were assessed in 61 Montreal IDUs in 2001, 85% of whom were reinterviewed within four weeks. The reliability of the IDUQOL was acceptable (ICC = 0.71) and concordance between the IDUQOL and the Flanagan Quality of Life Scale was moderate (Pearson coefficient = 0.57). Quality of life was negatively associated with injection cocaine and emergency department use with both instruments; these results were more striking for the IDUQOL. The IDUQOL is a culturally relevant quality of life instrument with good psychometric properties. The IDUQOL may be useful in the development and evaluation of interventions for IDUs.

In-patient benzodiazepine withdrawal: comparison of fixed and symptom-triggered taper methods

Fixed and symptom-triggered taper methods during in-patient benzodiazepine withdrawal treatment were compared using a randomized controlled design. Forty-four benzodiazepine users seeking in-patient withdrawal treatment at two substance use treatment clinics in Adelaide, Australia were recruited. Measurements included the Severity of Dependence Scale and the SF-36. A scale comprising six items from the Clinical Institute Withdrawal Assessment Scale--Benzodiazepines (CIWA-B) was used to measure withdrawal symptoms. Participants were randomized to receive a fixed diazepam tapering regime or diazepam only in response to withdrawal symptoms (symptom-triggered group). Results showed that there were no significant differences between treatment groups in terms of withdrawal severity, duration of in-patient treatment, amount of diazepam administered, treatment attrition and benzodiazepine use at follow-up. Both groups showed a reduction in benzodiazepine dosage of 86% over the first 8 days which was maintained at 1 month post-discharge. Although there were improvements in some subscales of the SF-36 between baseline and follow-up, values were significantly below age-matched norms at both time-points. This study showed that benzodiazepine users entering treatment have relatively poor health and that symptom-triggered taper methods incorporating flexible dosing and flexible treatment duration are as effective as fixed dose taper methods for in-patient benzodiazepine withdrawal treatment.

Health-related quality of life and virologic outcomes in an HIV clinic

OBJECTIVE

The purpose of this study was to describe the relationship between viral load and health-related quality of life (HRQOL) in a cohort of persons with human immunodeficiency virus (HIV) infection.

DESIGN

We evaluated HRQOL measurements in a clinical cohort of HIV-positive patients recruited from a university-associated HIV primary care clinic. HRQOL instruments included the medical outcomes survey-short form-36(MOS-SF-36) from which mental and physical component summary scores (MCS and PCS) and subscale scores were calculated.

RESULTS

Significant negative associations were found between viral load and SF-36 PCS, physical functioning (PF), role-physical (RP), bodily pain (BP), general health (GH), role-emotional (RE), and vitality (VT). Similar negative associations were found between CD4 cell count and SF-36 summary and subscale scores, with the notable exception of bodily pain. Multivariate analyses controlling for the effects of CD4 cell count and other clinical variables indicated viral load as an independent predictor of SF-36 PCS, RP, BP and VT scores.

CONCLUSIONS

The relationship between viral load, a measure of HIV disease activity, and several dimensions of the SF-36, a patient-focused measure of HRQOL, appears to be strong and independent of CD4 cell count. These findings suggest that having a lower viral load positively impacts the quality of life of HIV-positive patients.
