Evaluating the association between urine drug screening frequency and retention in opioid agonist treatment in Ontario, Canada: a retrospective cohort study.

OBJECTIVE: The objective of this study was to evaluate how urine drug screening (UDS) frequency is associated with retention in opioid agonist treatment (OAT). METHODS: Data for this retrospective cohort study of 55 921 adults in OAT in Ontario, Canada, were derived from administrative sources between 1 January 2011 and 31 December 2015. All patient information was linked anonymously across databases using encrypted health card numbers. Descriptive statistics were calculated for comparing UDS frequency groups using standardised differences (d) where d less than 10% indicated a statistically significant difference. A logistic regression model was then used to calculate ORs adjusting for baseline covariates, including sex, age, location of residence, income quintile, mental disorders, HIV status and deep tissue infections. RESULTS: Over 70% of the cohort had four or more UDS tests per month (weekly or more UDS). Significant associations were observed between UDS frequency and 1-year treatment retention in OAT biweekly (adjusted OR (aOR)=3.20, 95% CI 2.75 to 3.75); weekly UDS (aOR=6.86, 95% CI 5.88 to 8.00) and more than weekly (aOR=8.03, 95% CI 6.87 to 9.38) using the monthly or less groups as the reference. CONCLUSION: This study identified an association between weekly UDS and 1-year treatment retention in OAT. There is an active discussion within Canada about the utility of UDS. The lack of evidence for the impact of UDS on retention has left it open to some to argue they simply provide a barrier to patient engagement. Therefore, it is timely of this study to demonstrate that more frequent urine testing is not associated with a reduction in treatment retention.

The potential of assessment based on the WHO framework of intrinsic capacity in fragility fracture prevention.

The risk of falls associated with population ageing and the burden of chronic diseases increase the risk of fragility fractures. Globally, a large increase in the numbers of people sustaining fragility fractures is predicted. The management of highly vulnerable older persons who present and/or are at risk of fragility fractures is challenging given their clinical complexity and the fragmentation of the healthcare services. Fragility fractures frequently result in reduced functional ability and quality of life. Therefore, it is essential to implement person-centered models of care to address the individual's priorities and needs. In this context, the multidimensional construct of intrinsic capacity, composed of the critical functions on which the individual's functional ability rely, becomes of particular interest.In this article, the potential of current models to meet the global challenge is considered, particularly where healthcare systems are less integrated and poorly structured. It then describes how assessment of intrinsic capacity might provide the clinician with a holistic picture of an older individual's reserves before and after a fragility fracture and the implications of implementing this approach based on the construct of intrinsic capacity in healthcare systems, in both well-developed and low-resourced settings. It suggests that optimization of intrinsic capacity and functional ability is a credible conceptual model and might support a generally feasible approach to primary and secondary fracture prevention in older people.

The association between cannabis use and outcome in pharmacological treatment for opioid use disorder.

BACKGROUND: With the ongoing opioid crisis and policy changes regarding legalization of cannabis occurring around the world, it is necessary to consider cannabis use in the context of opioid use disorder (OUD) and its treatment. We aimed to examine (1) past-month cannabis use in patients with OUD, (2) self-reported cannabis-related side effects and craving, and (3) the association between specific characteristics of cannabis use and opioid use during treatment in cannabis users. METHODS: Participants receiving pharmacological treatment for OUD (n = 2315) were recruited from community-based addiction treatment clinics in Ontario, Canada, and provided information on past-month cannabis use (self-report). Participants were followed for 3 months with routine urine drug screens in order to assess opioid use during treatment. We used logistic regression analysis to explore (1) the association between any cannabis use and opioid use during treatment, and (2) amongst cannabis-users, specific cannabis use characteristics associated with opioid use. Qualitative methods were used to examine responses to the question: "What effect does marijuana have on your treatment?". RESULTS: Past-month cannabis use was reported by 51% of participants (n = 1178). Any cannabis use compared to non-use was not associated with opioid use (OR = 1.03, 95% CI 0.87-1.23, p = 0.703). Amongst cannabis users, nearly 70% reported daily use, and half reported experiencing cannabis-related side effects, with the most common side effects being slower thought process (26.2%) and lack of motivation (17.3%). For cannabis users, daily cannabis use was associated with lower odds of opioid use, when compared  with occasional use (OR = 0.61, 95% CI 0.47-0.79, p < 0.001) as was older age of onset of cannabis use (OR = 0.97, 95% CI 0.94, 0.99, p = 0.032), and reporting cannabis-related side effects (OR = 0.67, 95% CI 0.51, 0.85, p = 0.001). Altogether, 75% of cannabis users perceived no impact of cannabis on their OUD treatment. CONCLUSION: Past-month cannabis use was not associated with more or less opioid use during treatment. For patients who use cannabis, we identified specific characteristics of cannabis use associated with differential outcomes. Further examination of characteristics and patterns of cannabis use is warranted and may inform more tailored assessments and treatment recommendations.

Cannabis use during methadone maintenance treatment for opioid use disorder: a systematic review and meta-analysis.

BACKGROUND: Rates of cannabis use among patients receiving methadone maintenance therapy are high, and cannabis use may be associated with outcomes of methadone maintenance therapy. We examined the effect of cannabis use on opioid use in patients receiving methadone maintenance therapy to test the hypothesis that cannabis use is associated with a reduction in opioid use. METHODS: In this systematic review, we searched MEDLINE/PubMed, Embase, PsycINFO, CINAHL and ProQuest Dissertations and Theses Global from inception to July 12, 2018. We summarized the effects of cannabis use on opioid use during methadone maintenance therapy and treatment retention. We conducted meta-analyses using a random effects model. RESULTS: We included 23 studies in our review. We performed a meta-analysis of 6 studies, with a total number of participants of 3676, examining use of cannabis and opioids during methadone maintenance therapy. Owing to high heterogeneity, we described the studies qualitatively but provide the forest plots as supplemental material. The overall quality of evidence was very low, with a high risk of bias, owing to the nature of observational studies. INTERPRETATION: We found no consensus among studies that cannabis use is associated with reduced opioid use or longer treatment retention when used during methadone maintenance therapy in patients with opioid use disorder. PROSPERO Registration: CRD42015029372.

The association between health conditions and cannabis use in patients with opioid use disorder receiving methadone maintenance treatment.

BACKGROUND: Cannabis is the most commonly used substance among patients in methadone maintenance treatment (MMT) for opioid use disorder. Current treatment programmes neither screen nor manage cannabis use. The recent legalisation of cannabis in Canada incites consideration into how this may affect the current opioid crisis. AIMS: Investigate the health status of cannabis users in MMT. METHOD: Patients were recruited from addiction clinics in Ontario, Canada. Regression analyses were used to assess the association between adverse health conditions and cannabis use. Further analyses were used to assess sex differences and heaviness of cannabis use. RESULTS: We included 672 patients (49.9% cannabis users). Cannabis users were more likely to consume alcohol (odds ratio 1.46, 95% CI 1.04-2.06, P = 0.029) and have anxiety disorders (odds ratio 1.75, 95% CI 1.02-3.02, P = 0.043), but were less likely to use heroin (odds ratio 0.45, 95% CI 0.24-0.86, P = 0.016). There was no association between cannabis use and pain (odds ratio 0.98, 95% CI 0.94-1.03, P = 0.463). A significant association was seen between alcohol and cannabis use in women (odds ratio 1.79, 95% CI 1.06-3.02, P = 0.028), and anxiety disorders and cannabis use in men (odds ratio 2.59, 95% CI 1.21-5.53, P = 0.014). Heaviness of cannabis use was not associated with health outcomes. CONCLUSIONS: Our results suggest that cannabis use is common and associated with psychiatric comorbidities and substance use among patients in MMT, advocating for screening of cannabis use in this population. DECLARATION OF INTEREST: None.

Conceptualizing patient-centered care for substance use disorder treatment: findings from a systematic scoping review.

BACKGROUND: Despite ongoing efforts aimed to improve treatment engagement for people with substance-related disorders, evidence shows modest rates of utilization as well as client-perceived barriers to care. Patient-centered care (PCC) is one widely recognized approach that has been recommended as an evidence-based practice to improve the quality of substance use disorder treatment. PCC includes four core principles: a holistic and individualized focus to care, shared decision-making and enhanced therapeutic alliance. AIMS: This scoping review aimed to explore which PCC principles have been described and how they have defined and measured among people with substance-related disorders. METHODS: Following the iterative stages of the Arksey and O'Malley scoping review methodology, empirical (from Medline, Embase, PsycINFO, CINAHL and ISI Web of Science) and grey literature references were eligible if they focused on people accessing treatment for substance-related disorders and described PCC. Two reviewers independently screened the title/abstract and full-texts of references. Descriptive analyses and a directed content analysis were performed on extracted data. FINDINGS: One-hundred and forty-nine references met inclusion from the 2951 de-duplicated references screened. Therapeutic alliance was the most frequent principle of PCC described by references (72%); this was consistently defined by characteristics of empathy and non-judgment. Shared decision-making was identified in 36% of references and was primarily defined by client and provider strategies of negotiation in the treatment planning process. Individualized care was described by 30% of references and included individualized assessment and treatment delivery efforts. Holistic care was identified in 23% of references; it included an integrated delivery of substance use, health and psychosocial services via comprehensive care settings or coordination. Substance use and treatment engagement outcomes were most frequently described, regardless of PCC principle. CONCLUSIONS: This review represents a necessary first step to explore how PCC has been defined and measured for people accessing substance use disorder treatment. The directed content analysis revealed population and context-specific evidence regarding the defining characteristics of PCC-principles that can be used to further support the implementation of PCC.

Orthogeriatric co-management - managing frailty as well as fragility.

A high proportion of patients with fragility fracture, mainly hip fracture, have a variable degree of comorbidity and show some degree of dependence in basic or more complex activities of daily living. Evaluating these patents following the geriatric concept of frailty, about one third of hip fracture patients may be categorised as frail with high risk of poor outcomes and prolonged length of stay, one third as not frail, and about one third with an intermediate condition. Due to the high vulnerability, combined with the hip fracture event and surgical repair procedures, a multidisciplinary approach that includes geriatric competencies becomes essential to improve short and long-term outcomes after hip fracture. A key element of an effective process of care is a true co-managed approach that applies quality standards and provides a fast-track pathway of care, minimises the time the patient spends in bed, and reduces postoperative complications by means of standardised procedures. The occurrence of a fragility fracture is the strongest risk factor for a subsequent fracture. Moreover, frail subjects have a further risk of fracture due to high risk of falls - related to loss of muscle mass, multiple illnesses, impaired balance and weakness. Thus, effective secondary prevention strategies are essential to reduce morbidity and mortality after hip fracture, and they are currently a standard task of orthogeriatric care. Fracture liaison services (FLS) are probably the most efficient way of addressing secondary prevention including the assessment of both bone health and falls risk. Therefore, the optimal management of frail patients with fragility fracture includes both orthogeriatric care and FLS, which are complementary to each other. Orthogeriatric collaboration is also powerful in influencing healthcare policy. British experience as well as that in Ireland, Australia and New Zealand, have shown that when two widely disparate specialisms say the same thing, they may achieve a fundamental shift in attitudes and behaviour of both managers and clinicians. Furthermore, a continuous real-time audit, at national level, is a powerful driver for change and better standards of care.

The impact of cannabis use on patients enrolled in opioid agonist therapy in Ontario, Canada.

BACKGROUND: With the Canadian government legalizing cannabis in the year 2018, the potential harms to certain populations-including those with opioid use disorder-must be investigated. Cannabis is one of the most commonly used substances by patients who are engaged in medication-assisted treatment for opioid use disorder, the effects of which are largely unknown. In this study, we examine the impact of baseline and ongoing cannabis use, and whether these are impacted differentially by gender. METHODS: We conducted a retrospective cohort study using anonymized electronic medical records from 58 clinics offering opioid agonist therapy in Ontario, Canada. One-year treatment retention was the primary outcome of interest and was measured for patients who did and did not have a cannabis positive urine sample in their first month of treatment, and as a function of the proportion of cannabis-positive urine samples throughout treatment. RESULTS: Our cohort consisted of 644 patients, 328 of which were considered baseline cannabis users and 256 considered heavy users. Patients with baseline cannabis use and heavy cannabis use were at increased risk of dropout (38.9% and 48.1%, respectively). When evaluating these trends by gender, only female baseline users and male heavy users are at increased risk of premature dropout. INTERPRETATION: Both baseline and heavy cannabis use are predictive of decreased treatment retention, and differences do exist between genders. With cannabis being legalized in the near future, physicians should closely monitor cannabis-using patients and provide education surrounding the potential harms of using cannabis while receiving treatment for opioid use disorder.

Association between cannabis use and methadone maintenance treatment outcomes: an investigation into sex differences.

BACKGROUND: Cannabis will soon become legalized in Canada, and it is currently unclear how this will impact public health. Methadone maintenance treatment (MMT) is the most common pharmacological treatment for opioid use disorder (OUD), and despite its documented effectiveness, a large number of patients respond poorly and experience relapse to illicit opioids. Some studies implicate cannabis use as a risk factor for poor MMT response. Although it is well established that substance-use behaviors differ by sex, few of these studies have considered sex as a potential moderator. The current study aims to investigate sex differences in the association between cannabis use and illicit opioid use in a cohort of MMT patients. METHODS: This multicentre study recruited participants on MMT for OUD from Canadian Addiction Treatment Centre sites in Ontario, Canada. Sex differences in the association between any cannabis use and illicit opioid use were investigated using multivariable logistic regression. A secondary analysis was conducted to investigate the association with heaviness of cannabis use. RESULTS: The study included 414 men and 363 women with OUD receiving MMT. Cannabis use was significantly associated with illicit opioid use in women only (OR = 1.82, 95% CI 1.18, 2.82, p = 0.007). Heaviness of cannabis use was not associated with illicit opioid use in men or women. CONCLUSIONS: This is the largest study to date examining the association between cannabis use and illicit opioid use. Cannabis use may be a sex-specific predictor of poor response to MMT, such that women are more likely to use illicit opioids if they also use cannabis during treatment. Women may show improved treatment outcomes if cannabis use is addressed during MMT.

Sex differences in substance use, health, and social functioning among opioid users receiving methadone treatment: a multicenter cohort study.

BACKGROUND: Despite the growing numbers of men and women with opioid use disorder in Canada, sex-specific issues in treatment have not been re-examined in the current population of patients with opioid addiction. We aimed to evaluate sex differences in substance use, health, and social functioning among men and women currently receiving methadone treatment for opioid use disorder in Ontario, Canada. METHODS: We recruited 503 participants with opioid dependence disorder receiving methadone maintenance treatment. We collected data on demographics, treatment characteristics, psychiatric history, addiction severity, and drug use patterns through urinalysis. We performed adjusted univariate analyses and logistic regression to identify distinct factors affecting men and women. RESULTS: Among our sample of 54 % (n = 266) men and 46 % women (n = 226) with mean age 38.3 years, less than half of participants were employed (35.6 %) and married (31.8 %) and had completed a high school education (27.9 %). Compared to men, women had frequent physical and psychological health problems, family history of psychiatric illness, and childcare responsibilities and began using opioids through a physician prescription. Men had higher rates of employment, cigarette smoking, and cannabis use compared to women. CONCLUSIONS: Our results have revealed different patterns of substance use, health, and social functioning among men and women currently receiving methadone treatment for opioid addiction in Ontario, Canada. This information can be used to develop an integrative treatment regimen that caters to the individual needs of men and women, as well as to inform methadone treatment protocols to include specialized services (including vocational counseling, childcare and parenting assistance, medical assistance, relationship or domestic violence counseling, etc.) and increase their availability and accessibility on a larger scale.

A Community Care Model of Intravenous Antibiotic Therapy for Injection Drug Users with Deep Tissue Infection for "Reduce Leaving Against Medical Advice"

Deep tissue infection is a serious sequela that often demands intravenous (IV) antibiotic treatment. With respect to IV drug users (IDU's), research and lived experience demonstrates a trend of failed treatment outcomes, most notably associated with leaving hospital against medical advice (LAMA) prior to treatment completion, increased adverse outcomes and patient hardship. This paper examines an alternative model for delivering and completing IV antibiotic treatment to IDU's in a community care setting. A retrospective study was designed to review client characteristics. A total of 33 in-depth interviews were conducted with clients, clinicians and with staff. The impact of treatment adherence and completion, as well as client satisfaction of care was explored. A total of 165 patients were admitted during the study period. Osteomyelitis was the primary cause for IV antibiotics. Risk of leaving AMA was significantly lower for community model (p value <0.0000). Qualitative narrative analysis is also described with respect to satisfaction, stigma and the need for better models of care. With lower rates of LAMA a community model ought to be considered on a wider scale for provision of comprehensive support for populations with complex underlying health needs.

Can a community health worker and a trained traditional birth attendant work as a team to deliver child health interventions in rural Zambia?

BACKGROUND: Teaming is an accepted approach in health care settings but rarely practiced at the community level in developing countries. Save the Children trained and deployed teams of volunteer community health workers (CHWs) and trained traditional birth attendants (TBAs) to provide essential newborn and curative care for children aged 0-59 months in rural Zambia. This paper assessed whether CHWs and trained TBAs can work as teams to deliver interventions and ensure a continuum of care for all children under-five, including newborns. METHODS: We trained CHW-TBA teams in teaming concepts and assessed their level of teaming prospectively every six months for two years. The overall score was a function of both teamwork and taskwork. We also assessed personal, community and service factors likely to influence the level of teaming. RESULTS: We created forty-seven teams of predominantly younger, male CHWs and older, female trained TBAs. After two years of deployment, twenty-one teams scored "high", twelve scored "low," and fourteen were inactive. Teamwork was high for mutual trust, team cohesion, comprehension of team goals and objectives, and communication, but not for decision making/planning. Taskwork was high for joint behavior change communication and outreach services with local health workers, but not for intra-team referral. Teams with members residing within one hour's walking distance were more likely to score high. CONCLUSION: It is feasible for a CHW and a trained TBA to work as a team. This may be an approach to provide a continuum of care for children under-five including newborns.

Performance of Ethiopia's health system in delivering integrated community-based case management.

BACKGROUND: Analyzing complex health programs by their components and sub-components serves design, documentation, evaluation, research, and gap identification and prioritization. In 2012, we developed a rapid methodology to characterize integrated community case management (iCCM) programs, by assessing benchmarks for eight health system components in three program phases. OBJECTIVE. To assess iCCM benchmarks in Ethiopia three years after scale-up commenced, and to compare the benchmarks across the geographical region. METHODS. Six national iCCM experts scored each of 70 benchmarks (no, partial, or yes) and then were facilitated to reach consensus. RESULTS. Overall, iCCM benchmark achievement in Ethiopia was high (87.3%), highest for pre-introduction (93.0%), followed by introduction (87.9%) and scale-up (78.1%) phases. Achievement by system component was highest for coordination and policy (94.2%) and lowest for costing and finance (70.3%). Six regional, countries benchmark assessments, including two from Ethiopia 14 months apart, were highly correlated with program duration at scale (correlation coefficient: +0.88). CONCLUSION: Ethiopia has a mature, broad-based iCCM program. Despite limitations, the method described here rapidly, systematically, and validly characterized a complex program and highlighted areas for attention through government or partners.

Utilization of integrated community case management services in three regions in Ethiopia after two years of implementation.

BACKGROUND: The integrated community case management (iCCM) strategy has brought fully integrated treatment for sick children to the community in Ethiopia since 2010. OBJECTIVES: To describe patterns of use of iCCM services in 31 woredas (districts) in three regions of Ethiopia. METHODS: We analyzed all 60,452 encounters (58,341 [98.2%] for children 2-59 months of age and 2079 [1.8%] for children < 2 months of age) recorded in iCCM registration books from December 24, 2012 to January 15, 2013 in 622 randomly sampled health posts. RESULTS: Children 2-23 months constituted more than half (58.9%) of the total children treated, and about half of the registered infants < 2 months (1000/2079 [48.1%]) were not sick since some Health Extension Workers (HEWs) were recording well-infant visits. On average, sick children had 1.3 symptoms, more among children 2-59 months than among young infants (1.4 vs. 1.04, respectively). The main classifications for children 2-59 months were diarrhea with some or no dehydration (29.8%), pneumonia (20.7%), severe uncomplicated malnutrition (18.5%), malaria (11.2%), and other severe diseases (4.0%). More than half the sick children < 2 months (52.7%) had very severe disease. Treatment rates (per 1000 children per year) were low for all classifications: 11.9 for malaria (in malarious kebeles only), 20.3 for malnutrition, 21.2 for pneumonia, and 29.2 for diarrhea with wide regional variations, except for pneumonia. Nearly two-thirds of health posts (64%) treated ≤ 5 cases/month, but one treated 40. Health Extension Workers saw 60% more sick children 2-59 months in the third quarter of 2012 than in the third quarter of 2011. CONCLUSION: The use of iCCM services is low and increasing slowly, and the few busy health posts deserve further study. Recording healthy young infants in sick registers complicates tracking this vulnerable group.

Factors influencing the low utilization of curative child health services in Shebedino District, Sidama Zone, Ethiopia.

BACKGROUND: Use and coverage of curative interventions for childhood pneumonia, diarrhea, and malaria were low in Ethiopia before integrated community-based case management (iCCM). OBJECTIVES: To examine factors accounting for low use of iCCMin Shebedino District applying a "Pathway to Sur- vival" approach to assess illness recognition; home care; labeling and decision-making; patterns of care-seeking; access, availability and quality of care; and referral. METHODS: Shortly after introduction of iCCM, we conducted five studies in Shebedino District in May 2011: a population-based household survey; focus group discussions of mothers of recently ill children; key informant in- terviews, including knowledge assessment, with Health Extension Workers at health posts and with health workers at health centers; and an inventory of drugs, supplies, and job aids at health posts and health centers. RESULTS: The many barriers to use of evidence-based treatment included: (1) home remedies of uncertain effect and safety that delay care-seeking; (2) absent decision-maker; (3) fear of stigma; (4) expectation of non-availability of service or medicine; (5) geographic and financial barriers; (6) perception of (or actual) poor quality of care; and (7) accessible, available, affordable, reliable, non-standard, alternative sources of care. CONCLUSION: Only a system-strengthening approach can overcome such manifold barriers to use of curative care that has not increased much after ICCM introduction.

Measuring teamwork and taskwork of community-based "teams" delivering life-saving health interventions in rural Zambia: a qualitative study.

BACKGROUND: The use of teams is a well-known approach in a variety of settings, including health care, in both developed and developing countries. Team performance is comprised of teamwork and task work, and ascertaining whether a team is performing as expected to achieve the desired outcome has rarely been done in health care settings in resource-limited countries. Measuring teamwork requires identifying dimensions of teamwork or processes that comprise the teamwork construct, while taskwork requires identifying specific team functions. Since 2008 a community-based project in rural Zambia has teamed community health workers (CHWs) and traditional birth attendants (TBAs), supported by Neighborhood Health Committees (NHCs), to provide essential newborn and continuous curative care for children 0-59 months. This paper describes the process of developing a measure of teamwork and taskwork for community-based health teams in rural Zambia. METHODS: Six group discussions and pile-sorting sessions were conducted with three NHCs and three groups of CHW-TBA teams. Each session comprised six individuals. RESULTS: We selected 17 factors identified by participants as relevant for measuring teamwork in this rural setting. Participants endorsed seven functions as important to measure taskwork. To explain team performance, we assigned 20 factors into three sub-groups: personal, community-related and service-related. CONCLUSION: Community and culturally relevant processes, functions and factors were used to develop a tool for measuring teamwork and taskwork in this rural community and the tool was quite unique from tools used in developed countries.

World Health Organization/United Nations Children's Fund joint statement on integrated community case management: an equity-focused strategy to improve access to essential treatment services for children.

This statement presents the latest evidence for integrated community case management of childhood illness, describes the necessary program elements and support tools for effective implementation, and lays out actions that countries and partners can take to support the implementation of integrated community case management at scale.
