RESUMEN

BACKGROUND: Sleep is essential to health and affected by environmental and clinical factors. There is limited longitudinal research examining sleep quality in homeless older adults. OBJECTIVE: To examine the factors associated with poor sleep quality in a cohort of older adults in Oakland, California recruited while homeless using venue-based sampling and followed regardless of housing status. DESIGN: Longitudinal cohort study. PARTICIPANTS: 244 homeless-experienced adults aged ≥ 50 from the Health Outcomes in People Experiencing Homelessness in Older Middle Age (HOPE HOME) cohort. MAIN MEASURES: We assessed sleep quality using the Pittsburgh Sleep Quality Index (PSQI). We captured variables via biannual questionnaires and clinical assessments. KEY RESULTS: Our sample was predominantly men (71.3%), Black (82.8%), and had a median age of 58.0 years old (IQR 54.0, 61.0). Two-thirds of participants (67.2%) reported poor sleep during one or more study visits; sleep duration was the worst rated subdomain. In a multivariable model, having moderate-to-severe depressive symptoms (AOR 2.03, 95% CI 1.40-2.95), trouble remembering (AOR 1.56, 95% CI 1.11-2.19), fair or poor physical health (AOR 1.49, 95% CI 1.07-2.08), two or more chronic health conditions (AOR 1.76, 95% CI 1.18-2.62), any ADL impairment (AOR 1.85, 95% CI 1.36-2.52), and being lonely (AOR 1.55, 95% CI 1.13-2.12) were associated with increased odds of poor sleep quality. Having at least one confidant was associated with decreased odds of poor sleep (AOR 0.56, 95% CI 0.37-0.85). Current housing status was not significantly associated with poor sleep quality. CONCLUSIONS: Homeless-experienced older adults have a high prevalence of poor sleep. We found that participants' physical and mental health was related to poor sleep quality. Poor sleep continued when participants re-entered housing. Access to physical and mental healthcare, caregiving support, and programs that promote community may improve homeless-experienced older adults sleep quality, and therefore, their overall health.

RESUMEN

We examined the prevalence of self-reported motivations and barriers to helping intoxicated peers among emerging adults (N = 377; Mage = 18.64; 75% women, 88% White) attending a Southeastern university and whether motivations and barriers differed by age, gender, race, and class standing. Respondents aged 19-24 were more likely to endorse the motivation item "Because it was your "turn" to be the helper/designated driver (DD) that night" than eighteen-year-olds. Race differences were also reported for the motivation item, "Because the person was your friend", where White participants were more likely to endorse this item than non-White participants. Men also reported more Burden/Hassles-related barriers than did women.

RESUMEN

BACKGROUND: In the City and County of San Francisco, frequent users of emergent and urgent services across different settings (i.e., medical, mental health (MH), substance use disorder (SUD) services) are referred to as high users of multiple systems (HUMS). While often grouped together, frequent users of the health care system are likely a heterogenous population composed of subgroups with differential management needs. OBJECTIVE: To identify subgroups within this HUMS population using a cluster analysis. DESIGN: Cross-sectional study of HUMS patients for the 2019-2020 fiscal year using the Coordinated Care Management System (CCMS), San Francisco Department of Public Health's integrated data system. PARTICIPANTS: We calculated use scores based on nine types of urgent and emergent medical, MH, and SUD services and identified the top 5% of HUMS patients. Through k-medoids cluster analysis, we identified subgroups of HUMS patients. MAIN MEASURES: Subgroup-specific demographic, comorbidity, and service use profiles. KEY RESULTS: The top 5% of HUMS patients in the study period included 2657 individuals; 69.7% identified as men and 66.5% identified as non-White. We detected 5 subgroups: subgroup 1 (N = 298, 11.2%) who were relatively younger with prevalent MH and SUD comorbidities, and MH services use; subgroup 2 (N = 478, 18.0%), who were experiencing homelessness, with multiple comorbidities, and frequent use of medical services; subgroup 3 (N = 449, 16.9%), who disproportionately self-identified as Black, with prolonged homelessness, multiple comorbidities, and persistent HUMS status; subgroup 4 (N = 690, 26.0%), who were relatively older, disproportionately self-identified as Black, with prior homelessness, multiple comorbidities, and frequent use of medical services; and subgroup 5 (N=742, 27.9%), who disproportionately self-identified as Latinx, were housed, with medical comorbidities and frequent medical service use. CONCLUSIONS: Our study highlights the heterogeneity of HUMS patients. Interventions must be tailored to meet the needs of these diverse patient subgroups.

RESUMEN

BACKGROUND: The current opioid epidemic across the United States has fueled a surge in the rate of new hepatitis C virus (HCV) infections among young persons who inject drugs (PWIDs). Paramount to interrupting transmission is targeting these high-risk populations and understanding the underlying network structures facilitating transmission within these communities. METHODS: Deep sequencing data were obtained for 52 participants from 32 injecting partnerships enrolled in the U-Find-Out (UFO) Partner Study, which is a prospective study of self-described injecting dyad partnerships from a large community-based study of HCV infection in young adult PWIDs from San Francisco. Phylogenetically linked transmission events were identified using traditional genetic-distance measures and viral deep sequence phylogenies reconstructed to determine the statistical support of inferences and the direction of transmission within partnerships. RESULTS: Using deep sequencing data, we found that 12 of 32 partnerships were genetically similar and clustered. Three additional phylogenetic clusters were found describing novel putative transmission links outside of the injecting relationship. Transmission direction was inferred correctly for 5 partnerships with the incorrect transmission direction inferred in more than 50% of cases. Notably, we observed that phylogenetic linkage was most often associated with a lower number of network partners and involvement in a sexual relationship. CONCLUSIONS: Deep sequencing of HCV among self-described injecting partnerships demonstrates that the majority of transmission events originate from outside of the injecting partnership. Furthermore, these findings caution that phylogenetic methods may be unable to routinely infer the direction of transmission among PWIDs especially when transmission events occur in rapid succession within high-risk networks.

RESUMEN

Interactions among selection, gene flow, and drift affect the trajectory of adaptive evolution. In natural populations, the direction and magnitude of these processes can be variable across different spatial, temporal, or ontogenetic scales. Consequently, variability in evolutionary processes affects the predictability or stochasticity of microevolutionary outcomes. We studied an intertidal fish, Bathygobius cocosensis (Bleeker, 1854), to understand how space, time, and life stage structure genetic and phenotypic variation in a species with potentially extensive dispersal and a complex life cycle (larval dispersal preceding benthic recruitment). We sampled juvenile and adult life stages, at three sites, over three years. Genome-wide SNPs uncovered a pattern of chaotic genetic patchiness, that is, weak-but-significant patchy spatial genetic structure that was variable through time and between life stages. Outlier locus analyses suggested that targets of spatially divergent selection were mostly temporally variable, though a significant number of spatial outlier loci were shared between life stages. Head shape, a putatively ecologically responsive (adaptive) phenotype in B. cocosensis also exhibited high temporal variability within sites. However, consistent spatial relationships between sites indicated that environmental similarities among sites may generate predictable phenotype distributions across space. Our study highlights the complex microevolutionary dynamics of marine systems, where consideration of multiple ecological dimensions can reveal both predictable and stochastic patterns in the distributions of genetic and phenotypic variation. Such considerations probably apply to species that possess short, complex life cycles, have large dispersal potential and fecundities, and that inhabit heterogeneous environments.

RESUMEN

Most human pegivirus 2 (HPgV-2) infections are associated with past or current hepatitis C virus (HCV) infection. HPgV-2 is thought to be a bloodborne virus: higher prevalence of active infection has been found in populations with a history of parenteral exposure to viruses. We evaluated longitudinally collected blood samples obtained from injection drug users (IDUs) for active and resolved HPgV-2 infections using a combination of HPgV-2-specific molecular and serologic tests. We found evidence of HPgV-2 infection in 11.2% (22/197) of past or current HCV-infected IDUs, compared with 1.9% (4/205) of an HCV-negative IDU population. Testing of available longitudinal blood samples from HPgV-2-positive participants identified 5 with chronic infection (>6 months viremia in >3 timepoints); 2 were identified among the HCV-positive IDUs and 3 among the HCV-negative IDUs. Our findings indicate that HPgV-2 can establish chronic infection and replicate in the absence of HCV.

RESUMEN

Engagement in prevention services is crucial to reducing HIV risk among female entertainment and sex workers (FESW), and SMARTgirl is the national social marketing HIV prevention program for Cambodian women engaged in sex and entertainment work. Informed by the Behavioral Model of Vulnerable Populations, three multivariate logistic regression analyses examined correlates of three indices of engagement along the SMARTgirl HIV prevention continuum: (1) receipt of outreach services (past 3 months); (2) being registered as a SMARTgirl member; and (3) SMARTgirl club attendance (past year). Among the 1077 FESW enrolled in nine Cambodian provinces, women working in a brothel or freelance (adjusted odds ratio [aOR] 2.48; 95% CI 1.44-4.26) and those exchanging sex for drugs during the past 3 months (aOR 0.45; 95% CI 0.25-0.81) had significantly lower odds of contact with a SMARTgirl outreach worker. Women who reported having more than ten sexual partners in the past 3 months (aOR 0.54; 95% CI 0.32-0.89) and those who reported binge alcohol use (aOR 0.53; 95% CI 0.29-0.98) had significantly lower odds of being registered as SMARTgirl members. Exchanging sex for drugs was also associated with increased odds of attending a SMARTgirl club (aOR 2.03; 95% CI 1.04-3.98). Novel methods to deliver HIV prevention services are warranted to more effectively reach FESW who exchange sex for drugs, engage in binge alcohol use, report a greater number of sexual partners, and those not working in established work venues.

RESUMEN

Housing status affects drug using behaviors, but less is known about the relationship between housing patterns and hepatitis C virus (HCV) infection. HCV-negative young people who inject drugs (PWID) were enrolled into a prospective cohort (2003-2019) with quarterly study visits. We used Cox regression to estimate the independent association of recent housing status (housed vs. unhoused, housing stability, and housing trajectory) on HCV incidence. Among 712 participants, 245 incident HCV infections occurred over 963.8 person-years (py) (cumulative incidence 24.4/100 py). An inverse relationship between time housed and HCV incidence was observed (always unhoused 45.0/100 py, 95% confidence interval (CI) 37.1, 54.5; variably housed 18.0/100 py, 95% CI 15.0, 21.3; and always housed 7.0/100 py, 95% CI 3.0, 17.3). In Cox regression models controlling for confounders, those unhoused versus housed at baseline had a 1.9-fold increased infection risk (95% CI 1.4, 2.6). Those always unhoused versus always housed had a 1.5 times greater risk of HCV (95% CI 1.0, 2.3), and those spending a portion of time in stable housing a lower risk (adjusted relative hazard 0.05, 95% CI 0.3, 0.9) with a similar trend for those being housed for less time. Young adult PWID experiencing both recent and chronic states of being unhoused are at elevated risk for HCV infection. Importantly for this group of PWID, our findings indicate that some frequency of residential housing significantly reduces HCV infection risk.

RESUMEN

Female entertainment and sex workers (FESW) are vulnerable to violence, which impedes safer sex behaviors and increases risk of HIV. FESW are also disproportionately affected by co-occurring psychosocial health conditions, including substance use, depression, and economic insecurity, which increased risk of exposure to violence. We used a syndemic framework to examine the effects of co-occurring psychosocial conditions on the risk of client-perpetrated physical and sexual violence against FESW. Data were collected among 1198 Cambodian FESW on recent client-perpetrated physical and sexual violence, and psychosocial conditions (psychological distress, alcohol consumption, amphetamine-type stimulant (ATS) use, debts, housing, and food insecurity). Bivariate and multivariate logistic regressions were conducted. Prevalence of physical and sexual violence from clients was 4.8% and 6.9%, respectively. Client-perpetrated physical violence was associated with housing insecurity, ATS use, and psychological distress. All psychosocial conditions, except ATS, were associated with exposure to sexual violence. In multivariable models, odds of client-perpetrated physical violence were twice higher among women with ≥ 4 compared to ≤ 3 psychosocial conditions. Risk of sexual violence increased with the number of psychosocial conditions. Compared to those with ≤ 1 condition, FESW with two psychosocial conditions had twice the odds (AOR = 2.08; 95% CI 1.00-4.31) and women with 5-6 psychosocial conditions had eightfold higher odds (AOR = 8.10; 95% CI 3.4-19.31) of sexual violence from clients. Our findings support a syndemic model of co-occurring psychosocial conditions among FESW that are associated with increased risk of violence. Violence prevention interventions targeting FESW should adopt comprehensive approaches that address co-occurring psychosocial conditions.

RESUMEN

In the United States, hepatitis C virus (HCV) transmission is rising among people who inject drugs (PWID). Many regions have insufficient prevention intervention coverage. Using modeling, we investigated the impact of scaling up prevention and treatment interventions on HCV transmission among PWID in Perry County, Kentucky, and San Francisco, California, where HCV seroprevalence among PWID is >50%. A greater proportion of PWID access medication-assisted treatment (MAT) or syringe service programs (SSP) in urban San Francisco (established community) than in rural Perry County (young, expanding community). We modeled the proportion of HCV-infected PWID needing HCV treatment annually to reduce HCV incidence by 90% by 2030, with and without MAT scale-up (50% coverage, both settings) and SSP scale-up (Perry County only) from 2017. With current MAT and SSP coverage during 2017-2030, HCV incidence would increase in Perry County (from 21.3 to 22.6 per 100 person-years) and decrease in San Francisco (from 12.9 to 11.9 per 100 person-years). With concurrent MAT and SSP scale-up, 5% per year of HCV-infected PWID would need HCV treatment in Perry County to achieve incidence targets-13% per year without MAT and SSP scale-up. In San Francisco, a similar proportion would need HCV treatment (10% per year) irrespective of MAT scale-up. Reaching the same impact by 2025 would require increases in treatment rates of 45%-82%. Achievable provision of HCV treatment, alongside MAT and SSP scale-up (Perry County) and MAT scale-up (San Francisco), could reduce HCV incidence.

RESUMEN

We measured HIV incidence rate, trend and risk factors in 564 HIV-negative young people (< 30 years) who inject drugs (PWID) in San Francisco between 2000 and 2014. HIV incidence was 0.93/100 person-years (PY; 95% CI 0.50, 1.73). Incidence varied between 0.62/100 PY in 2000-2002 and 1.06/100 PY in 2012-2014 (P for trend = 1.0). HIV incidence varied significantly (P < 0.01) by race/ethnicity: among Hispanics it was 8.19/100 PY (95% CI 3.41, 19.68), African-Americans 4.59/100 PY (95% CI 1.15, 18.37), and Whites 0.26/100 PY (95% CI 0.06, 1.03). Male participants who reported sex with men (MSM) had higher HIV incidence (2.63/100 PY; 95% CI 1.31, 5.25) compared to males who did not report MSM (0.50/100 PY; 95% CI 0.12, 1.99) (P = 0.01). Despite an overall stable HIV incidence trend, incidence was elevated among African-American and Hispanic PWID, and men who have sex with men. Addressing prevention needs in these key populations is critical for the goal of eliminating HIV transmission.

RESUMEN

BACKGROUND: While HIV and unintended pregnancies are both occupational risks faced by female sex workers, the epidemiology of pregnancy and its drivers in this population remains understudied. This includes Cambodia, where the drivers of pregnancy among female entertainment and sex workers (FESW) remain unknown. The current study aimed to examine factors associated with incident pregnancy, as well as describe contraceptive use among FESW in Phnom Penh, Cambodia. METHODS: This analysis drew from the Young Women's Health Study (YWHS)-2, a 12-month observational cohort of 220 FESW aged 15-29 years, conducted between August 2009 and August 2010. Interviewer-administered questionnaires were conducted at baseline and quarterly thereafter, alongside HIV and pregnancy testing. Bivariate and multivariable extended Cox regression analysis was used to examine correlates of incident pregnancy. RESULTS: At baseline, 6.8% of participants were pregnant, and only 10.8% reported using hormonal contraceptives, with 11.3% reporting an abortion in the past 3 months. Pregnancy incidence was high, at 22/100 person-years (95% CI: 16.3-30.1). In multivariable analysis, younger age (19-24 years versus 25-29 years) (Adjusted Hazards Ratio (AHR): 2.28; 95% Confidence Interval (CI) 1.22-4.27), lower income (400,000-600,000 Riel (≤150$USD) versus > 600,000 Riel (> 150$USD)) (AHR 2.63; 95% CI 1.02-6.77) positively predicted pregnancy, while higher self-reported condom self-efficacy were associated with reduced pregnancy incidence (AHR 0.89; 95% CI 0.81-0.98). CONCLUSIONS: Results document high incidence of pregnancy and unmet reproductive health needs among FESWs in Cambodia. Findings point to an urgent need for multi-level interventions, including venue-based HIV/STI and violence prevention interventions, in the context of legal and policy reform. High pregnancy incidence in this population may also undermine recruitment and retention into HIV prevention intervention trials. The exploration of innovative and comprehensive sex worker-tailored sexual and reproductive health service models, also as part of HIV prevention intervention trials, is warranted.

RESUMEN

The purpose of this study was to examine alcohol and tobacco access points among a sample of rural and urban youth. Through collaboration with four regional school districts, a local drug prevention coalition administered a survey to a sample of 445 youth representing 30 different communities in a central U.S. region. The survey items included demographics, 30-day use measures, and questions about points-of-access for alcohol and tobacco. Results showed no differences among points-of-access between urban and rural youth. Ability to obtain alcohol from family, peers, other non-peer youth, and other non-family adults (P < 0.05) were each statistically significant predictors of 30-day alcohol use. Ability to obtain tobacco from family, peers, other non-peer youth, other non-family adults, and self-purchase (P < 0.05) were statistically significant predictors of 30-day tobacco use. Access through peers was the strongest predictor for both 30-day alcohol and tobacco use. Determining the primary social points-of-access youth use to obtain alcohol and tobacco can assist in the development of appropriate community-level prevention strategies and policies.

RESUMEN

BACKGROUND: To date, research applying the Sexual Relationship Power Scale (SRPS) has been limited to sexual risk behaviors. OBJECTIVE: We measured levels of sexual relationship power and examined associations between sexual relationship power and injecting and sexual behaviors that place women at increased risk for blood borne infections. METHODS: Using data from a cross-sectional study of young women who inject drugs (WWID) in San Francisco, USA, logistic regression analysis identified independent associations between SRPS and subscale scores (relationship control [RC] and decision making dominance [DMD]) and injecting and sexual behaviors. RESULTS: Of the 68 young WWID, 24 (34%) reported receptive syringe sharing, 38 (56%) reused/shared a cooker to prepare drugs, and 25 (37%) injected someone else's drug residue during the three-months prior to enrollment. Most (60, 88%) reported condomless sex with main sex-partner, 8 (12%) reported transactional sex, and 36 (53%) had two or more recent sex partners. The median SRPS score was 2.98 (IQR: 2.65, 3.18), 3.23 (IQR: 3.23, 3.57) for RC and 2.40 (IQR: 2.20, 2.60) for DMD. No significant associations were detected between SRPS or DMD and injecting or sexual risk behaviors. After adjusting for gender and years injecting, for every one-point increase in RC, women had a 6.70 lower odds of recent condomless sex (95%CI: 0.92, 50.00, p = 0.06), and a 3.90 lower odds of recent transactional sex (95%CI: 1.22, 12.50, p = 0.02). CONCLUSION: Our study findings suggest that some components of sexual relationship power may play a role in sexual risk, but not in injecting risk.

RESUMEN

AIM: This commentary presents a cost-benefit analysis to advocate for the use of succession planning to mitigate the problems ensuing from nurse manager turnover. BACKGROUND: An estimated 75% of nurse managers will leave the workforce by 2020. Many benefits are associated with proactively identifying and developing internal candidates. Fewer than 7% of health care organisations have implemented formal leadership succession planning programmes. EVALUATION: A cost-benefit analysis of a formal succession-planning programme from one hospital illustrates the benefits of the programme in their organisation and can be replicated easily. KEY ISSUES: Assumptions of nursing manager succession planning cost-benefit analysis are identified and discussed. The succession planning exemplar demonstrates the integration of cost-benefit analysis principles. CONCLUSION: Comparing the costs of a formal nurse manager succession planning strategy with the status quo results in a positive cost-benefit ratio. IMPLICATIONS FOR NURSING MANAGEMENT: The implementation of a formal nurse manager succession planning programme effectively reduces replacement costs and time to transition into the new role. This programme provides an internal pipeline of future leaders who will be more successful than external candidates. Using an actual cost-benefit analysis equips nurse managers with valuable evidence depicting succession planning as a viable business strategy.

RESUMEN

OBJECTIVES: To determine the association between multiple drug use and nonfatal overdose among young people (younger than 30 years) who inject drugs. METHODS: We completed a longitudinal study of 173 injection drug users younger than 30 years living in San Francisco, California, between April 2012 and February 2014. RESULTS: The odds of nonfatal overdose increased significantly as heroin and benzodiazepine pill-taking days increased and when alcohol consumption exceeded 10 drinks per day compared with 0 drinks per day. CONCLUSIONS: Heroin, benzodiazepine, and alcohol use were independently associated with nonfatal overdose over time among young people who inject drugs. Efforts to address multiple central nervous system depressant use remain an important component of a comprehensive approach to overdose, particularly among young people.

RESUMEN

The Kaposi's sarcoma-associated herpes virus (KSHV) K3 viral gene product effectively down-regulates cell surface MHC class I. K3 is an E3 ubiquitin ligase that promotes Lys(63)-linked polyubiquitination of MHC class I, providing the signal for clathrin-mediated endocytosis. Endocytosis is followed by sorting into the intralumenal vesicles (ILVs) of multivesicular bodies (MVBs) and eventual delivery to lysosomes. The sorting of MHC class I into MVBs requires many individual proteins of the four endosomal sorting complexes required for transport (ESCRTs). In HeLa cells expressing the KSHV K3 ubiquitin ligase, the effect of RNAi-mediated depletion of individual proteins of the ESCRT-0 and ESCRT-I complexes and three ESCRT-III proteins showed that these are required to down-regulate MHC class I. However, depletion of proteins of the ESCRT-II complex or of the ESCRT-III protein, VPS20 (vacuolar protein sorting 20)/CHMP6 (charged MVB protein 6), failed to prevent the loss of MHC class I from the cell surface. Depletion of histidine domain phosphotyrosine phosphatase (HD-PTP) resulted in an increase in the cell surface concentration of MHC class I in HeLa cells expressing the KSHV K3 ubiquitin ligase. Rescue experiments with wild-type (WT) and mutant HD-PTP supported the conclusion that HD-PTP acts as an alternative to ESCRT-II and VPS20/CHMP6 as a link between the ESCRT-I and those ESCRT-III protein(s) necessary for ILV formation. Thus, the down-regulation of cell surface MHC class I, polyubiquitinated by the KSHV K3 ubiquitin ligase, does not employ the canonical ESCRT pathway, but instead utilizes an alternative pathway in which HD-PTP replaces ESCRT-II and VPS20/CHMP6.

RESUMEN

Conditional cash transfer (CCT) and cognitive-behavioral treatments are evidence-based approaches to reduce stimulant use and sexual risk taking. We describe the adaptation and implementation of sequential behavioral interventions for Cambodian female entertainment and sex workers (FESW) who use amphetamine-type stimulants (ATS): (1) a 12-week CCT intervention; and (2) a 4-week cognitive-behavioral aftercare (AC) group. An ongoing cluster randomized stepped wedge trial in 10 Cambodian provinces is enrolling FESW with confirmed recent ATS use to examine the effectiveness of CCT + AC. In the first six provinces, 138 of the 183 eligible FESW (75 %) enrolled in CCT and completed a median of 25 (interquartile range 9-32) of the 36 urine screening visits. Of the 84 participants who were eligible for AC, 79 completed at least one session (94 %) and 57 completed three or more sessions (68 %). Culturally tailored behavioral interventions to reduce ATS use and optimize HIV prevention are feasible in resource-limited settings.

RESUMEN

OBJECTIVES: To describe the creation of a clinical pharmacy technician position within the U.S. Army and to identify the personal skills and characteristics required to meet the demands of this role. SETTING: An outpatient military treatment facility located in Maryland. PRACTICE DESCRIPTION: The clinical pharmacy technician position was designed to support clinical pharmacy services within a patient-centered medical home. PRACTICE INNOVATION: Funding and a position description were established to hire a clinical pharmacy technician. Expected duties included administrative (45%), patient education (30%), and dispensing (25%). Local policy, in accordance with federal law and U.S. Army regulations, was developed to define the expanded technician responsibility to deliver patient medication education. RESULTS: In the initial 3 months, the clinical pharmacy technician spent 24 hours per week on clinical activities, affording an additional 10-15 hours per week for clinical pharmacists to provide patient care. Completed consults increased from 41% to 56%, and patient-pharmacist encounters increased from 240 to 290 per month. The technician, acting as a clinical pharmacist extender, also completed an average of 90 patient encounters independently each month. As a result of these improvements, the decision was made to hire a second technician. Currently, the technicians spend 28-40 hours per week on clinical activities, offsetting an average of 26 hours per week for the clinical pharmacists. CONCLUSION: A patient-centered medical home clinical pharmacy technician can reduce the administrative workload for clinical pharmacists, improve their efficiency, and enhance the use of clinical pharmacy services. Several characteristics, particularly medication knowledge, make pharmacy technicians particularly suited for this role. The results from the implementation of a clinical pharmacy technician at this military treatment facility resulted in an Army-wide expansion of the position and suggested applicability in other practice sites, particularly in federal pharmacies.

RESUMEN

AIMS: To test the value of phosphatidylethanol (PEth) as a biomarker for alcohol consumption among injecting drug users (IDUs). METHODS: As part of a longitudinal study of young IDUs, dried blood spots and self-reported alcohol by structured interview were collected at baseline. We compared self-reported alcohol use to detectable PEth (≥8 ng/ml) in the blood spots as well as the relationships between quantitative PEth results and quantity measures of alcohol consumption. RESULTS: There were strong associations between PEth and self-reported categorical measures of alcohol consumption (all P < 0.01). There was high specificity for reporting abstaining from alcohol; 94% of those who reported not consuming alcohol in the prior month tested negative for PEth. PEth was well correlated with measures of alcohol use (e.g. with reported number of days drinking in the prior month: Spearman r = 0.70 (P < 0.001)). CONCLUSIONS: The positive correlation of PEth with reported alcohol consumption suggests that PEth may be a useful marker in settings where alcohol consumption is difficult to assess, or to corroborate or invalidate self-reported measures of alcohol consumption.
