Assisted injection among people who inject drugs in Thailand

Background

Assisted injection is common among people who inject drugs (IDU), and has been associated with elevated risk for HIV infection and overdose. However, this practice has not been explored in the Asian context, including in Thailand, where HIV prevalence among IDU remains high.

Methods

Using multivariate logistic regression, we examined the prevalence and correlates of assisted injecting among IDU participating in the Mitsampan Community Research Project in Bangkok. We also sought to identify reasons for engaging in assisted injecting and those who provide this form of assistance.

Results

In total, 430 IDU participated in this study, including 376 (87.5%) who reported having ever required assistance injecting, and 81 (18.8%) who reported assisted injecting in the previous six months. In multivariate analyses, assisted injecting in the previous six months was independently and positively associated with being female (adjusted odds ratio [AOR]?=?2.42; 95% confidence interval [CI]: 1.40 – 4.18), being a weekly heroin injector (AOR?=?1.78; 95% CI: 0.99 – 3.20), syringe sharing (AOR?=?2.08; 95% CI: 1.18 – 3.68) and soft-tissue infection (AOR?=?3.51; 95% CI: 1.43 – 2.53). Having a longer injecting career (AOR?=?0.96; 95% CI: 0.94 – 0.99) was negatively associated with assisted injecting. Primary reasons given for engaging in assisted injecting included being new to injecting and lacking knowledge on how to inject. The most common providers of assistance with injecting were close friends.

Conclusion

We found a high prevalence of assisted injecting among IDU in Bangkok, with females, frequent heroin injectors, those with shorter injecting careers being more likely to engage in this practice. Those who require help with the injecting process are more likely to share syringes, and have skin infections. These findings indicate the need for interventions focused on promoting safer and self-administered injections.

     

Knowledge and possession of take-home naloxone kits among street-involved youth in a Canadian setting: a cohort study

Background

The distribution of take-home naloxone (THN) kits has been an important strategy in reducing overdose fatalities among people who use drugs. However, little is known about the use of THN among youth who are street-involved. The present study explores knowledge and possession of THN among street-involved youth in a Canadian setting.

Methods

Data were derived from the At-Risk Youth Study (ARYS), a prospective cohort of street-involved youth age 14–28 at enrollment in Vancouver, Canada. Participants completed a standardized questionnaire, which included items related to knowledge and possession of THN, sociodemographic characteristics, and substance use-related factors. Multivariable logistic regression models were used to identify factors independently associated with knowledge and possession of THN.

Results

Between December 2014 and November 2016, 177 youth were interviewed, including 68 females (38.4%). While 126 (71.2%) participants reported knowledge of THN, only 40 (22.6%) possessed a THN kit. Caucasian/white ethnicity was found to be positively associated with both knowledge and possession of THN (both p?<?0.05). Public injection drug use in the last 6 months was found to be positively associated with knowledge of THN, while daily heroin use and daily methamphetamine use were associated with possession of THN (all p?<?0.05). Male gender was negatively associated with possession of THN (p?<?0.05).

Conclusions

These findings highlight important gaps between knowledge and possession of THN among youth and the need to increase participation in THN programs among specific populations including non-white and male youth. Further research is needed to gain a better understanding of the barriers that may prevent certain youth from acquiring THN kits.

     

Characteristics of persons who inject drugs and who witness opioid overdoses in Vietnam: a cross-sectional analysis to inform future overdose prevention programs

Background

Persons who use opioids have a high risk of overdose and associated mortality. In Vietnam, little is known about the characteristics of this population and the persons who are witness to those overdoses. One approach to combatting fatal overdose has been the use of peer interventions in which a friend or injecting partner administers overdose reversal medication, but availability in Vietnam of these medications is limited to pilot programs with aims to expand in the future (Le Minh and V.F. Go, Personal Communication, 2016). The primary objective of this paper is to explore the characteristics associated with witnessing three or more overdoses in a lifetime.

Methods

This cross-sectional analysis used baseline data from a four-arm randomized control trial conducted in Thai Nguyen, Vietnam, known as the Prevention for Positives project. One thousand six hundred seventy-three PWID were included in the analysis. We conducted bivariable and multivariable logistic regression to identify characteristics associated with witnessing three or more overdoses in a lifetime. Characteristics explored included education, employment, marital status, risky drug use behaviors, locations for accessing syringes, recent overdose, history of incarceration, drug treatment, and having slept outside in the past 3 months.

Results

Seventy-two percent (n = 1203) of participants had witnessed at least one overdose in their lifetime, and 46% had witnessed three or more overdoses (n = 765). In the multivariable model, having less than secondary education (AOR 0.70; 95% CI 0.57, 0.86), having slept outside in the past 3 months (AOR 1.77; 95% CI 1.31, 2.40), having a history of incarceration (AOR 1.33; 95% CI 1.07, 1.65), having a history of drug treatment (AOR 1.41; 95% CI 1.12, 1.77), experiencing a recent non-fatal overdose (AOR 3.84; 95% CI 2.36, 6.25), injecting drugs daily (AOR 1.79; 95% CI 1.45, 2.20), receptive needle sharing (AOR 1.30; 95% CI 1.04, 1.63), and number of years injecting (AOR 1.04; 95% CI 1.02, 1.07) were significantly associated with witnessing three or more overdoses.

Conclusions

Targeted interventions are needed to train persons witnessing an overdose to administer overdose-reversal medication. This includes targeting persons prior to release from prisons, drug treatment centers, and those accessing syringe exchange programs. Additional research should assess the burden of witnessing an overdose as well as locations for medication distribution. Assessments of the training capacity and needs for implementing these programs among drug using peers in Vietnam are of the utmost importance.

     

Barriers and facilitators to hepatitis C (HCV) screening and treatment—a description of prisoners’ perspective

Background

Hepatitis C virus (HCV) infection is a global epidemic with an estimated 71 million people infected worldwide. People who inject drugs (PWID) are overrepresented in prison populations globally and have higher levels of HCV infection than the general population. Despite increased access to primary health care while in prison, many HCV infected prisoners do not engage with screening or treatment. With recent advances in treatment regimes, HCV in now a curable and preventable disease and prisons provide an ideal opportunity to engage this hard to reach population.

Aim

To identify barriers and enablers to HCV screening and treatment in prisons.

Methods

A qualitative study of four prisoner focus groups (n =?46) conducted at two prison settings in Dublin, Ireland.

Results

The following barriers to HCV screening and treatment were identified: lack of knowledge, concerns regarding confidentiality and stigma experienced and inconsistent and delayed access to prison health services. Enablers identified included; access to health care, opt-out screening at committal, peer support, and stability of prison life which removed many of the competing priorities associated with life on the outside. Unique blocks and enablers to HCV treatment reported were fear of treatment and having a liver biopsy, the requirement to go to hospital and in-reach hepatology services and fibroscanning.

Conclusion

The many barriers and enablers to HCV screening and treatment reported by Irish prisoners will inform both national and international public health HCV elimination strategies. Incarceration provides a unique opportunity to upscale HCV treatment and linkage to the community would support effectiveness.

     

Contemporary women prisoners health experiences,unique prison health care needs and health care outcomes in sub Saharan Africa: a scoping review of extant literature.

Background

Sub Saharan African (SSA) prisons have seen a substantial increase in women prisoners in recent years. Despite this increase, women prisoners constitute a minority in male dominated prison environments, and their special health needs are often neglected. Research activity on prison health remains scant in SSA, with gathering of strategic information generally restricted to infectious diseases (human immunodeficiency virus infection HIV/tuberculosis TB), and particularly focused on male prisoners. Health care provisions for women (and pregnant women) in SSA prisons are anecdotally reported to fall far short of the equivalence care standards mandated by human rights and international recommendations, and the recent agreements set out in the Southern African Development Community (SADC) Minimum Standards for HIV in Prisons.

Methods

A scoping review mapped what is currently known about women prisoners’ health experiences, unique prison health care needs and health care outcomes in SSA. A systematic search collected and reviewed all available and relevant published and grey literature (2000–2017). Following removal of duplicates and application of exclusion measures, 46 records remained, which represented 18 of the 49 SSA countries. These records were subsequently charted and thematically analysed.

Results

Three themes were generated; ‘The Prison Regime’; ‘Navigating inside the Prison Health Infrastructure’ and ‘Accessing the outside Community and Primary Care Health Services’. Women in SSA prisons experience the same substandard nutrition, overcrowding and unhygienic conditions which exacerbate poor health and infectious disease transmission as males. Human rights abuses, substandard prison conditions and poor access to prison based and community clinical care, along with the invisible nature of women and that of their unique health needs are deplorable.

Conclusions

The review has highlighted the dearth of gender specific strategic information on women prisoners in the region, appalling environmental conditions and prison health care provision, and violation of human rights for those incarcerated. Enhanced donor support, resource allocation, prison health and population health policy reform, health systems surveillance and gender sensitive prison health service provision is warranted. This will help address women prisoners’ conditions and their specific health needs in SSA prisons, and ultimately bridge the gap between prison and population health in the region.

     

FRAIL-NH predicts outcomes in long term care

Background/Objectives

To investigate the predictive validity of the short, simple FRAIL-NH frailty screening tool in the long term care population and to then compare the predictive validity with the frailty index (FI) for 6-month adverse health outcomes.

Design

Retrospective study using the Minimum Data Set (MDS) 3.0 and chart review from June-December 2014.

Setting

Two Long Term Care Facilities in Saint Louis, MO.

Participants

270 patients ages ≥ 65 years old residing in long term care.

Measurements

Frailty was measured using the FRAIL-NH and Frailty Index (FI) criteria. Adverse outcomes measured at 6-month follow-up included falls, hospitalizations, and hospice enrollment/mortality.

Results

Based on screening tool used frailty prevalence was 48.7% for FRAIL-NH and 30.3% for FI. The FRAIL-NH pre-frail (Adjusted Odds Ratio [AOR]=2.62; 95% Confidence Interval [CI]=1.25–5.54; p=0.11) classification was associated with 6 month risk of falling and mortality/hospice enrollment was associated with the frail classification, AOR=3.96 (1.44–10.87, p=0.007). Combining the pre-frail and frail categories both measures predicted 6 month mortality with the FRAIL-NH being the strongest predictor (AOR=3.36; 95%CI=1.26–8.98; p=0.016) and the FI was a more modest predictor with an AOR of 2.28; 95%CI=1.01–5.15; p=0.047. When directly comparing the FRAIL-NH to the FI, the FRAIL-NH pre-frail were at increased risk of falling, AOR=2.42 (1.11–5.92, p=0.027) and the FRAIL-NH frail were at increased risk of hospice enrollment/death, OR=3.25 (1.04–10.86) p=0.044.

Conclusion

In comparison to the FI, the FRAIL-NH preformed just as well at screening for frailty and was a slightly better predictor of adverse outcomes. The FRAIL-NH is a brief, easy-to-administer frailty screening tool appropriate for long term care patients and predicts increased risk of falls in the pre-frail and mortality/hospice enrollment in the frail.

     

Factors related to the quality of life of older prisoners

Purposes

There is evidence of an increasing emphasis on the relevance of the quality of life-paradigm as an outcome measure for clients in geriatric, forensic, as well as correctional care. This paper aims to explore to what extent variables that were categorized according to the main areas of the Good Lives Model (‘the self’, ‘the body’ and ‘social life’) are related to the quality of life domains of older imprisoned offenders.

Methods

Data were collected by means of a structured questionnaire administered in individual interviews with 93 older prisoners aged 60 years and over in 16 prisons of the Dutch-speaking region in Belgium. Characteristics of the main GLM-areas were identified by specifically designed items as well three validated instruments (psychiatric disorders, loneliness, and frailty). Dependent variables consisted of the four sub-domains of the WHOQOL-BREF instrument which measures quality of life in four domains, namely: (1) physical health, (2) psychological health, (3) social relationships, and (4) environment. Structural equation modelling (SEM) was used for statistical analysis.

Results

Individual variables, such as satisfaction with activities, were related to the older prisoners’ QoL in several domains simultaneously. Other than suicidal ideation, psychopathological symptoms had no significant relation to quality of life.

Conclusions

Approaches enabling older prisoner to disclose their interests, experiences, and feelings are important in prison. Special attention should be given to psychiatric and age-related symptoms of older prisoners, since they may not be noted by the prison staff, as older prisoners seem to be poorer self-advocates as compared to their younger peers.

     

Prevalence and associated factors of anemia among adolescent girls attending high schools in Dembia District,Northwest Ethiopia, 2017

Introduction

Anemia is a global public health problem affecting both developing and developed countries. In Ethiopia, Adolescent girls are more vulnerable to anemia because of gender norms can leave girls disproportionately impacted by food insecurity, increased iron requirements related to their rapid growth, and menstrual loss. However, evidence on the problem is scarce because it has not been given due attention in Ethiopia. Therefore, this study assessed the prevalence and associated factors of anemia among late adolescent girls attending high schools in Dembia District, northwest Ethiopia.

Methods

A school based cross-sectional study was conducted in Dembia District from March 1 to April 30/ 2017. Out of the randomly selected three high schools, 462 adolescents were included using the simple random sampling technique. A Standardized structured questionnaire was used to collect data. Capillary blood samples were drawn from adolescents using a portable Hb201+ instrument to measure hemoglobin. A bivariate and multivariable binary logistic regression analyses were employed to identify factors associated with anemia. Adjusted Odds Ratio (AOR) with a corresponding 95% Confidence Interval (CI) was computed to show the strength of associations.

Results

The overall prevalence of anaemia among adolescent girls was 25.5%, (95%CI, 21.4, and 29.2). Of the total anemic adolescents, 109(92.4%) had mild anaemia, while 7(5.9%) and 2(1.7%) were found with moderate and severe anaemia, respectively. Dietary diversity score ((AOR =4.2(95% CI;1.7, 10.5)), household food security status ((AOR?=?4.1(95% CI; 1.3, 13.2)), living status of adolescents with either of the two parents((AOR?=?2;(95%CI;1.14,3.6)) and guardians ((AOR?=?2.4;(95% CI;1.02,5.6)) showed statistically significant association with anemia.

Conclusion

Anemia is a moderate public health problem in Dembia District. Dietary diversity score, household food security status, and living status of adolescents were the key determinants of anemia. Therefore, the government should focus on preventing food insecurity with increasing productivity to improve dietary diversification of the adolescent girls.

Trial registration

Retrospectively registered.

     

The prevalence of asymptomatic malaria parasitemia and associated factors among adults in Dembia district,northwest Ethiopia, 2017

Background

Malaria is still a leading cause of morbidity and mortality in many developing countries including Ethiopia. Its prevalence has been declining among Ethiopian adults, especially in Dembia district. However, it is still at the top of diseases list at the district. Hence, the study aimed to determine the prevalence and the factors that contribute to its being the major public health concern despite different preventive and control measures in place.

Methods

A community based cross-sectional study was conducted from October 11 to November 16, 2017. The multistage sampling technique was employed to select 832 study participants. A rapid diagnostic test were used to confirm the disease. Data were entered using Epi info version 7 and was analyzed by Statistical Package for Social Science (SPSS) version 20. The logistic regression model was performed to examine the association of factors with malaria parasite.

Results

Out of the 832 adults included in the study, 6.7% (95% Confidence Interval (CI: 5.2–8.7)) were confirmed to be malaria parasite carriers. The dominant plasmodium species was Plasmodium falciparum [46 (82%)]. According to the multivariable logistic regression analysis, male sex (Adjusted Odds Ratio (AOR?=?4.5; 95%CI: 2.1–9.5), adult age 15–19?years (AOR?=?4.5; 95%CI: 2.1–9.7), travel history (AOR?=?5; 95%CI: 2.34–12.25), and stagnant water around home (AOR?=?3.7; 95%CI: 1.57–8.87) increased the probability of malaria infectivity, while Insecticidal Treated Nets (ITN) utilization (AOR?=?0.2; 95%CI: 0.09–0.31) decreased it.

Conclusion

Malaria is still an important public health challenge among adults in the study area. Male sex, age 15–19?years, travel history, living around stagnant water, and not using ITN increased the probability of infection. Therefore, the District Health office and Health extension workers should work to increase ITN distribution and focus on reducing malaria breading sites through community participation.

     

To serve or to leave: a question faced by public sector healthcare providers in Pakistan

Background

The availability of properly trained and motivated providers is a prerequisite for provision of easily accessible healthcare. Pakistan has been listed by the World Health Organization in its World Health Report 2006 as one of 57 countries with a critical health workforce deficiency. This study examines the factors associated with the willingness of public sector healthcare providers to leave government service and recommends measures that can be adopted to attract and retain staff in the country’s public healthcare system.

Methods

A stratified, random sampling methodology was adopted to recruit a nationally representative sample of 1,296 public sector healthcare providers, including paramedics, medical doctors, and specialists. A semi-structured questionnaire was used to interview these providers. Logistic regressions measured the association with determinants of their willingness to leave the public health sector for better prospects elsewhere.

Results

A third of all healthcare providers who were interviewed were of the view that, provided the opportunity, they would leave government service. The odds of willingness to leave service were highest among providers from the region of Azad Jammu and Kashmir (adjusted odds ratio [AOR]?=?4.33; 95% CI, 2.49–7.54) followed by the province of Balochistan (AOR?=?4.21; 95% CI, 2.41–7.33), and the region of Gilgit Baltistan (AOR?=?3.34; 95% CI, 1.67–6.67). Providers who expressed dissatisfaction in the manner their performance was evaluated and those who were dissatisfied with the current salary, each had higher odds of considering leaving government service (AOR?=?1.67; 95% CI, 1.18–2.40 and AOR?=?2.03; 95% CI, 1.47–2.81, respectively). Providers who reported experiencing interference in their work by influential politicians of the area were more inclined to leave (AOR?=?1.44; 95% CI, 1.05–1.98).

Conclusion

This study clearly highlights the need to implement more focused strategies in the public healthcare system in Pakistan in order to build sufficient staff motivation and prevent providers from leaving government service. In order to improve coverage of healthcare services in Pakistan, the government will have to introduce more focused interventions to attract and retain healthcare providers, especially in remote and rural areas of the country.

     

Perceptions of healthcare professionals on the usage of percutaneous endoscopic gastrostomy in a teaching hospital from a middle-income South East Asian country

Objective

To explore the perceptions of healthcare professionals’ (HCPs) in a South East Asian nation towards percutaneous endoscopic gastrostomy (PEG) feeding.

Design

Semi-structured, qualitative interviews.

Settings

A teaching hospital in Kuala Lumpur, Malaysia.

Participants

A total of 17 healthcare professionals aged 23-43 years, 82% women.

Results

Thematic analysis revealed five themes that represent HCPs’ perceptions in relation to the usage of PEG feeding: 1) knowledge of HCPs, 2) communication, 3) understanding among patients, and 4) financial and affordability.

Conclusion

The rationale for reluctance towards PEG feeding observed in this regions was explained by lack of education, knowledge, communication, team work, and financial support. Future studies should assess the effects of educational programmes among HCPs and changes in policies to promote affordability on the utilization of PEG feeding in this region.

     

Association between body mass index and all-cause mortality among oldest old Chinese

Objectives

To examine the association between BMI and all-cause mortality in the oldest old (≥80 years).

Design

The study used a prospective cohort study design.

Setting

Chinese Longitudinal Healthy Longevity Survey (CLHLS) between 1998/99 and 2011.

Population

8026 participants aged 80 years and older were followed every two to three years.

Measurements

Body weight and knee height were measured. Height was calculated based on knee height using a validated equation. Deaths were ascertained from family members during follow-up.

Results

The mean BMI was 19.8 (SD 4.5) kg/m². The prevalence of underweight, overweight and obese was 37.5%, 10.2% and 4.4%, respectively. There were 5962 deaths during 29503 person-years of follow-up. Compared with normal weight, underweight was associated with a higher mortality risk (HRs: 1.20 (95%CI 1.13-1.27) but overweight (HR 0.89 (95%CI 0.81-0.99)) were associated with a lower risk. Obesity had a HR 0.91 (95%CI 0.78-1.05) for mortality.

Conclusion

Among oldest old Chinese, underweight is associated with an increased risk of all-cause mortality but overweight is associated with a reduced risk. Interventions to reduce undernutrition should be given priority among the oldest old Chinese.

     

Effects of nutritional supplements on muscle mass and activities of daily living in elderly rehabilitation patients with decreased muscle mass: A randomized controlled trial

Objective

To investigate the effects of nutritional intervention with resistance training on skeletal muscle mass in elderly patients with disabilities in a convalescent rehabilitation setting.

Design

A randomized controlled trial. (UMIN Clinical Trials Registry ID: UMIN000006238).

Setting

A rehabilitation hospital.

Participants

39 elderly patients with decreased skeletal muscle mass in an inpatient convalescence rehabilitation unit.

Interventions

A combination of resistance training plus nutritional supplementation (R/N group) or resistance training alone (R group). The training and supplementation were conducted essentially from the patient’s admission to discharge (2–6 months).

Outcome Measures

The patients were evaluated at the time of admission and at the end of the intervention for skeletal muscle mass (calf circumference [CC] as a primary outcome, and arm circumference [AC]), hand grip strength (HG), Mini-Nutritional Assessment-Short Form (MNA®-SF) score, serum albumin level (Alb), body mass index (BMI), and activities of daily living (ADL) as represented by the Barthel Index (BI) score.

Results

Significant treatment effects were seen for CC, AC, BI, Alb in the R/N group compared to the R group. A mean treatment effect of 3.2 (95%CI: 2.0–4.4) was seen in CC, 1.4 (95%CI: 0.8–2.1) was seen in AC, 11.2 (95%CI: 0.5–21.8) was seen in BI, 0.3 (95%CI: 0.1–0.5) was seen in Alb.

Conclusion

The results of this study suggest that nutritional intervention added to resistance training during convalescent rehabilitation may improve skeletal muscle mass and activities of daily living.

     

Predictors of primary care referrals to a vascular disease prevention lifestyle program among participants in a cluster randomised trial

Background

Cardiovascular disease accounts for a large burden of disease, but is amenable to prevention through lifestyle modification. This paper examines patient and practice predictors of referral to a lifestyle modification program (LMP) offered as part of a cluster randomised controlled trial (RCT) of prevention of vascular disease in primary care.

Methods

Data from the intervention arm of a cluster RCT which recruited 36 practices through two rural and three urban primary care organisations were used. In each practice, 160 eligible high risk patients were invited to participate. Practices were randomly allocated to intervention or control groups. Intervention practice staff were trained in screening, motivational interviewing and counselling and encouraged to refer high risk patients to a LMP involving individual and group sessions. Data include patient surveys; clinical audit; practice survey on capacity for preventive care; referral records from the LMP. Predictors of referral were examined using multi-level logistic regression modelling after adjustment for confounding factors.

Results

Of 301 eligible patients, 190 (63.1%) were referred to the LMP. Independent predictors of referral were baseline BMI ≥ 25 (OR 2.87 95%CI:1.10, 7.47), physical inactivity (OR 2.90 95%CI:1.36,6.14), contemplation/preparation/action stage of change for physical activity (OR 2.75 95%CI:1.07, 7.03), rural location (OR 12.50 95%CI:1.43, 109.7) and smaller practice size (1–3 GPs) (OR 16.05 95%CI:2.74, 94.24).

Conclusions

Providing a well-structured evidence-based lifestyle intervention, free of charge to patients, with coordination and support for referral processes resulted in over 60% of participating high risk patients being referred for disease prevention. Contrary to expectations, referrals were more frequent from rural and smaller practices suggesting that these practices may be more ready to engage with these programs.

Interventions that improve health-related quality of life in patients with myocardial infarction

Purpose

Patients with myocardial infarction (MI) often report lower health-related quality of life (HRQoL) than those without MI. Interventions can affect HRQoL of these patients. The purpose of this review was to identify effective strategies for improving HRQoL among individuals with MI.

Methods

Three electronic databases were searched and limited to articles peer-reviewed and published in English between 1995 and 2015. We screened titles and abstracts of the retrieved articles for studies that examined effectiveness of interventions to improve HRQoL in patients with MI.

Results

Twenty-three studies were found that examined the effects of behavioural interventions—cardiac rehabilitation programmes (CRP), education and counselling programmes, and other psychological and cognitive interventions—to improve HRQoL in patients with MI. The studies included were mainly randomised controlled trials (14 studies) with a wide age range of participants (18–80 years) and a mean age group of 50–70 years. CRPs, including home- and hospital-based CRPs, regular weekly aerobic training programmes, and group counselling mostly resulted in improvement of HRQoL in patients with MI.

Conclusion

Most CRPs and other interventions were beneficial to MI patients. Therefore, patients with MI should be encouraged to participate in programmes that can help promote their HRQoL.

     

Rigidity,dyskinesia and other atypical overdose presentations observed at a supervised injection site,Vancouver, Canada

Objective

In midst of the overdose crisis, the clinical features of opioid overdoses seem to be changing. Understanding of the adverse effects of synthetic opioids such as fentanyl is currently limited to clinical settings. Insite, a supervised injection site in Vancouver, Canada, provides an opportunity to better understand illicit drug overdose presentations.

Methods

A review of clinical records at Insite for October 2016 to April 2017 was undertaken to quantify atypical overdose presentations. Overdose reports were reviewed for the number of atypical opioid overdose presentations, temporal trends over the study period, concurrent symptoms, and interventions employed by staff.

Results

Insite staff responded to 1581 overdoses during the study period, including 497 (31.4%) that did not fit a typical presentation for opioid overdoses. Of these, 485 fit into five categories of atypical features: muscle rigidity, dyskinesia, slow or irregular heart rate, confusion, and anisocoria. Muscle rigidity was the most common atypical presentation, observed in 240 (15.2%) of the overdose cases, followed by dyskinesia, observed in 150 (9.2%). Slow or irregular heart rate was observed in 69 (4.4%) cases, confusion in 24 (1.5%), and anisocoria in 2 (0.1%) of overall overdose cases.

Discussion

The similarity of atypical overdose cases at Insite with anesthesiology case reports supports the understanding that the illicit drug supply is contaminated by fentanyl and other synthetic opioids. Atypical overdose presentations can affect clinical overdose response. The experience at Insite highlights the potential for supervised consumption sites to be innovative spaces for community learning and knowledge translation.

     

Muscle,Health and Costs: A Glance at their Relationship

Objective

To assess the association between muscle parameters (mass, strength, physical performance) and activities of daily living (ADL), quality of life (QoL), and health care costs.

Design

Cross-sectional Maastricht Sarcopenia Study (MaSS).

Setting

Community-dwelling, assisted-living, residential living facility.

Participants

227 adults aged 65 and older.

Measurements

Muscle mass, hand grip strength and physical performance were assessed by bio-electrical impedance, JAMAR dynamometer and the Short Physical Performance Battery, respectively. Health outcomes were measured by the Groningen Activity Restriction Scale (disability in ADL) and the EQ-5D-5L (QoL). Health care costs were calculated based on health care use in the past three months.

Results

Muscle strength and physical performance showed a strong correlation with ADL, QoL, and health care costs (P<.01); for muscle mass no significant correlations were observed. Regression analyses showed that higher gait speed (OR 0.06, 95%CI 0.01-0.55) was associated with a lower probability of ADL disability. Furthermore, slower chair stand (OR 1.23, 95%CI 1.08-1.42), and more comorbidities (OR 1.58, 95%CI 1.23-2.02) were explanatory factors for higher ADL disability. Explanatory factors for QoL and costs were: more disability in ADL (OR 1.26, 95%CI 1.12-1.41 for QoL; B = 0.09, P<.01 for costs) and more comorbidities (OR 1.44, 95%CI 1.14-1.82 for QoL; B = 0.35, P<.01 for costs).

Conclusion

Lower gait speed and chair stand were potential drivers of disability in ADL. Disability in ADL and comorbidities were associated with QoL and health care costs in community-dwelling older adults. Improving physical performance may be a valuable target for future intervention and research to impact health burden and costs.
