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.

Psychosocial impact of repeat HIV-negative testing: a follow-up study.

Continued sexual risk behavior following repeatedly testing HIV-negative in the Polaris HIV Seroconversion Study (Ontario, Canada) led to this follow-up study which identifies the impact of repeat negative testing among 64 men and women. Repeat HIV-negative testing frequently results in confusion as to what constitutes risk and occasionally to thoughts of HIV immunity. Narrative accounts include beliefs that monogamy constitutes safety from HIV, that psychosocial factors other than repeatedly testing negative leads to risk, and that sexual risk reduction is unsustainable. In conclusion, the repeat negative test experience for some neither clarifies risk behavior nor reinforces sustained risk reduction.

Rehabilitation in HIV/AIDS: development of an expanded conceptual framework.

In industrialized countries where HIV infection is becoming a chronic, episodic condition, rehabilitation services have the potential to play an expanded role for people living with HIV/AIDS (PLHAs). However, little is known about rehabilitation in the context of HIV. This paper documents the development of an enhanced, multidisciplinary conceptual framework of rehabilitation in the context of HIV, using the perceptions of PLHAs and rehabilitation professionals. Rehabilitation, broadly defined, is a dynamic process that includes all prevention and/or treatment activities and/or services that address body impairments, activity limitations and participation restrictions for an individual. The framework was developed through broad consultation and interviews with thirteen key informants. Themes that emerged from analysis of interviews related to concepts of rehabilitation in the context of HIV, rehabilitation professionals' roles in the context of HIV, and barriers to access and delivery of rehabilitation services. While there was some variation, key informants generally viewed rehabilitation as a goal-oriented and client-centered process with the potential to impact a range of life domains. Themes were presented to members of a national advisory committee (including PLHAs and health care providers), who produced the foundation of the HIV rehabilitation framework. The framework uses the perspective of the person living with HIV/AIDS, and includes individual life domains that may be affected by HIV, drawing and expanding upon the World Health Organization's (WHO's) International Classification of Functioning, Disability and Health.

Pushing the boundaries of outreach work: the case of needle exchange outreach programs in Canada.

In this paper, we examine the challenges of defining the boundaries of outreach work using the example of needle exchange programs. In particular, we examine the multiple and inter-related factors that extend needle exchange outreach work beyond its official mandate. Using semi-structured interviews, 59 workers at 15 programs in Ontario, Canada were asked questions about operational policies and routines. An iterative and inductive analytic process was used. Over time, most outreach workers develop a well-defined sense of the activities they consider to be consistent with a harm reduction approach and the types of conduct that are considered to be acceptable and professional. Workers conceptualize their roles to encompass education and support but are reluctant to impose a rigid definition of their roles. A pragmatic and humble stance combined with strong beliefs in social justice encourages workers to find informal solutions to meet client needs that extend beyond the program mandate. As a result, doing 'extra' is the norm. These extra efforts are informal, but often regular, expansions of the service complement. Construction of flexible boundaries provides opportunities to meet many client needs and unexpected situations; however, going the extra-mile strains resources. A minority of workers blur the boundaries between private and professional lives. Further, a variety of personal, social and socio-political forces encourage outreach workers to continually redefine the boundaries of their roles and service complements.

Voluntary HIV testing among inmates: sociodemographic, behavioral risk, and attitudinal correlates.

We sought to determine the prevalence and correlates of self-reported HIV testing among inmates in correctional centers in Ontario, Canada. A cross-sectional survey was conducted with a stratified random sample of 597 male and female adult inmates. The participation rate was 89%. Descriptive statistics and multiple logistic regression were used to analyze HIV testing. Fifty-eight percent had ever been tested, and 21% had voluntarily tested while incarcerated in the past year. Having ever been tested was more common among those at risk for HIV through injection drug use (IDU) or sexual behavior. Testing while incarcerated in the past year was independently associated with being single (OR = 2.6), frequent IDU (OR = 4.0), not having casual sex partners prior to incarceration (OR = 0.53), a history of hepatitis (OR = 2.4), previous HIV testing (OR = 3.7), a close relationship with an HIV-positive person in the outside community (OR = 1.7), knowing an HIV-positive person inside (OR = 2.7), a perceived chance of being infected during incarceration (OR = 2.2), and support of mandatory testing (OR = 2.0). The predominant motivations for testing while incarcerated were IDU or fears of infection inside, possibly through contact with blood, during fights, or even by casual contact. Voluntary HIV testing in prison should be encouraged, and inmates should receive appropriate counseling and information to allow realistic assessment of risk.

Delayed application of condoms is a risk factor for human immunodeficiency virus infection among homosexual and bisexual men.

The objective of this analysis was to identify risk factors for recent human immunodeficiency virus (HIV) infection among homosexual and bisexual men in Ontario, Canada, during 1998-2001. Participants were recruited through the provincial HIV diagnostic laboratory and through physicians and community organizations. HIV test results were used to identify recent seroconverters (cases). A subsample of 183 men (62 cases and 121 controls) enrolled in the Polaris HIV Seroconversion Study as of June 2001 was analyzed. This analysis focused on sexual behaviors with partners who were HIV-positive or whose HIV status was unknown. In multiple logistic regression, independent risk factors were identified. Rates of unprotected receptive oral, insertive anal, and receptive anal sex and delayed application of condoms during receptive anal sex (RAS) were significantly higher among cases (97%, 41%, 53%, and 32%, respectively) than among controls (73%, 19%, 14%, and 2%). Independent risk factors for HIV infection were RAS without condoms (odds ratio = 4.4, p = 0.0004) and delayed application of condoms during RAS (odds ratio = 5.8, p = 0.01). There was an association with condom failure (breakage or slippage) during RAS that approached significance (odds ratio = 2.9, p = 0.09). Delayed application of condoms for RAS may result in contact with preejaculatory fluid. This behavior, which to date has received little attention, may pose as much risk for HIV infection as fully unprotected RAS.

Prior opiate injection and incarceration history predict injection drug use among inmates.

AIMS: To describe injection drug use among inmates, and to identify correlates of drug injection while incarcerated. DESIGN: Cross-sectional survey. SETTING: Six provincial correctional centres in Ontario, Canada. PARTICIPANTS: Face-to-face interviews were conducted with a random sample of 439 adult males and 158 females. MEASUREMENTS: Inmates were asked about drug use in their lifetime, outside the year prior to their current incarceration, and while incarcerated in the past year. Among the 32% (189 / 597) with a prior history of drug injection, independent correlates of injection while incarcerated in the past year were identified using multiple logistic regression. FINDINGS: Among all inmates while incarcerated in the past year, 45% (269 /597) used drugs and 19% (113 / 596) used non-cannabis drugs. Among those with a prior history of injecting, 11% (20 / 189) injected while incarcerated in the past year. Rates of injection with used needles were the same pre-incarceration as they were while incarcerated (32%). Independent correlates of drug injection while incarcerated were injection of heroin (OR = 6.4) or other opiates (OR = 7.9) and not injected with used needles (OR = 0.20) outside in the year prior to incarceration, and ever being incarcerated in a federal prison (OR = 5.3). CONCLUSIONS: The possibility of transmission of human immunodeficiency virus (HIV), hepatitis C (HCV) or other blood-borne diseases exists in Ontario correctional centres. In this setting, drug injection while incarcerated is primarily related to opiate use prior to incarceration. The correlation between injecting and extensive incarceration history suggests missed opportunities to improve inmates' health.

Factors underlying anxiety in HIV testing: risk perceptions, stigma, and the patient-provider power dynamic.

Client anxiety is often associated with diagnostic testing. In this study, the authors used a grounded theory approach to examine the situational and social factors underlying anxiety associated with HIV testing, analyzing transcripts from semistructured interviews with 39 HIV test recipients in Ontario, Canada (selected based on HIV serostatus, risk experience, geographic region, gender, and number of HIV tests), then integrating emergent themes with existing research literature. Analysis revealed four themes: perceptions of risk and responsibility for health, stigma associated with HIV, the patient-provider power dynamic, and techniques used by test recipients to enhance control in their interactions with providers. Service implications include modifications to information provision during the test session, attention to privacy and anonymity, and sensitivity to patient-provider interactions.

Symptomatic primary HIV infection or risk experiences? Circumstances surrounding HIV testing and diagnosis among recent seroconverters.

Our objective was to understand the circumstances surrounding HIV testing among recent HIV seroconverters (n=80) compared to HIV-negative controls (n=106) in Ontario, Canada using self-reported interview data. Diagnosis of symptomatic primary HIV infection (SPHI) was defined as diagnosis by the participant's physician. Testing in response to symptoms was reported by 42% of seroconverters vs 12% of controls. More controls than seroconverters tested in response to risk behaviour (70% vs 50%) or from a desire to know their status (34% vs 12%). Among seroconverters, 76% reported 'flu-like' illness during the time period of infection, 66% had symptoms consistent with SPHI, and 35% reported a physician's diagnosis of SPHI. Compared to seroconverters with undiagnosed SPHI, more of those diagnosed with SPHI had rash (odds ratio=4.5). SPHI plays a significant role in HIV testing and subsequent early diagnosis in this population. More seroconversions could be diagnosed with better patient and physician awareness of its symptoms.

HIV testing and counseling: test providers' experiences of best practices.

Although education is central to HIV testing and counseling, little is known about the educational processes within the testing experience. This study investigated test providers' understandings of testing and counseling best practices. Interviews with a purposive sample of 24 test providers were thematically analyzed. Analysis revealed five best practices specific to HIV education and public health--ensuring information and education for HIV risk reduction, individualization of risk assessment, ensuring test results are given in person, providing information and referrals, and facilitating partner notification--and six practices not specific to HIV counseling relationship building. The latter were building trust and rapport; maintaining professional boundaries; ensuring a comfortable, safe environment; ensuring confidentiality; imparting nonjudgmntal attitude; and self-determination. The identified best practices demonstrated remarkable consistency across respondent subgroups. Although counseling was seen as largely educational and with a preventive focus, it included individualized messages based on assessments of risk, knowledge, and social and cultural characteristics.

Increases in HIV incidence among men who have sex with men undergoing repeat diagnostic HIV testing in Ontario, Canada.

OBJECTIVE: To estimate HIV incidence density for different exposure categories among people undergoing repeat testing in Ontario, Canada. METHODS: Persons using voluntary, diagnostic HIV testing at least twice were identified by computerized and manual record linkage. In the 1992-2000 period, 980 seroconverters and 340 994 repeat negative testers contributed 936 145 person years (PY) of observation. Incidence density (ID) was calculated according to Kitayaporn et al. Poisson regression was used to evaluate differences in incidence. RESULTS: Among men who have sex with men (MSM), ID declined between 1992-1996, from 1.23 per 100 PY in 1992 to 0.79 per 100 PY in 1996 [relative risk (RR), 0.86 per year; 95% confidence interval (CI), 0.77-0.96]. Subsequently, ID increased to 1.39 per 100 PY in 1999 (RR, 1.18 per year; 95% CI, 1.05-1.34). In 2000, ID was 1.16 per 100 PY but this decrease was not statistically significantly different from 1999. MSM in their twenties had the highest ID in 1992-1996, but in 1996-2000 MSM in their thirties had the highest risk of infection. Among injecting drug users (IDU), ID decreased from 0.64 per 100 PY in 1992 to 0.14 per 100 PY in 2000 (RR, 0.87 per year; 95% CI, 0.80-0.94). Among heterosexuals, annual incidence remained constant at about 0.03 per 100 PY in 1992-2000. CONCLUSIONS: Increases in ID were identified among MSM from 1996 to 1999. These findings are consistent with other research. Continued vigilance and improved surveillance are needed to better understand and control the epidemic.

Desired elements of HIV testing services: test recipient perspectives.

Thematic analysis of transcripts from interviews with a purposive sample of 39 voluntary human immunodeficiency virus (HIV) test recipients in Ontario (selected on the basis of HIV serostatus, risk behaviors, region of residence, gender, and testing format) was used to identify elements of HIV testing services of concern to test recipients. Colleague review was used to ensure dependability of findings, and emergent themes were compared with the existing literature on patient satisfaction. Data analysis identified a comprehensive set of 28 service elements, including components related to access and availability (convenience, physical accessibility, familiarity), structure of the service (privacy, and characteristics of the venue, session, and test provider), technical and medical aspects of the testing process (including blood-taking, file maintenance, obtaining informed consent, waiting period, and manner of result provision), and both cognitive and socioemotional aspects of the interpersonal process (including decision-making support, personalized risk information, receipt of appropriate emotional support, and service referrals). Results suggest that information on, and training in, counseling skills for both physician and nonphysician test counselors is important in the provision of quality testing services. Results also suggest that test recipients would appreciate choice in testing service options, and within the test session, individualized information, and counseling.

Needle exchange: how the meanings ascribed to needles impact exchange practices and policies.

The consistency among needle exchange practices, HIV prevention, harm reduction goals, and potential program effectiveness are analyzed. Using a modified ethnographic approach, qualitative interviews were conducted with staff (n = 59) of needle exchange programs (NEPs; n = 15). Interviews addressed operational policies; funding and challenges. An iterative, inductive analytic process was used. Differences in exchange practices are traced to differences in how workers define needles as objects of "risk" and/or "prevention." The weight accorded to each definition has implications for service delivery. Among NEPs that ascribe a "risk" meaning, workers enforce a strict one-for-one exchange, encourage clients to take fewer needles, and penalize clients. Programs that focus on the "prevention" meaning of needles work towards improving access, problem solving about proper disposal and do not penalize clients. Operational policies that restrict access to sterile equipment or discourage attendance need to be reconsidered if HIV prevention goals are to be realized.

Needle exchange programs. Delivery and access issues.

OBJECTIVE: Examine the challenges of four service delivery models (i.e., fixed, mobile, satellite and home visits) and how service delivery may impact on NEP HIV prevention efforts. METHODS: Using a modified ethnographic approach, semi-structured interviews concerning policies and procedures were conducted with staff (n = 59) of NEPs (n = 15) in Ontario. An iterative, inductive analytic process was used. RESULTS: According to workers and managers, effectiveness of NEP prevention efforts depend on client development and retention and service design. Fixed and satellite sites, home visits and mobile services provide varied levels of temporal and spatial accessibility. Combining modes of delivery can offset the disadvantages of individual modes. DISCUSSION: NEP evaluations that do not consider service and resource factors run the risk of concluding that NEPs are ineffective when it may be that the program works for a small proportion of IDUs whom the NEP has the resources to serve.

Regional variation in HIV prevalence and risk behaviours in Ontario injection drug users (IDU).

OBJECTIVES: To measure HIV prevalence, risk behaviours, and further service needs in needle exchange programs throughout Ontario, and to conduct regional comparisons. METHODS: Injection drug users (IDU) recruited through the efforts of needle exchange programme (NEP) staff in 9 Ontario cities during 1997-98 completed questionnaires about their drug use and behaviours and provided saliva and/or dried blood samples for anonymous unlinked HIV testing. RESULTS: Demographic and drug use characteristics of participants showed great regional variation. HIV prevalence by region ranged from 1.4% to 14.7%. In addition to region, HIV positivity was associated with injecting for more than 5 years, use of (powder) cocaine, use of crack, binge injection (10 or more times per day at least once in the previous 6 months), and being a longer-term NEP user. Sharing of injection equipment, and especially of other drug injection materials such as water and cookers, remain important issues, although much of the sharing reported is with only one other person. Unmet demand for methadone treatment was identified despite changes in regulation of methadone provision designed to make it more accessible. CONCLUSIONS: This study suggested significant further HIV prevention needs among IDU throughout Ontario. There is also evidence of potential to provide additional services such as methadone at NEPs if the required resources are invested. NEPs that have succeeded in gaining the trust of high-risk IDU offer a means to provide access to needed services.

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.
