Homeless women’s service use,barriers, and motivation for participating in substance use treatment

Background: Homeless women are at high risk for substance use disorder (SUD), and are a growing proportion of the homeless population. However, homeless women experience barriers to engaging in substance use services. Objectives: Among homeless women with SUD, to explore service use, motivation to change, service barriers, and willingness to have substance use and mental health problems addressed in primary health care. Methods: Women with SUD were sampled from 11 Health Care for the Homeless (HCH) primary care clinics in 9 states, yielding 241 with either an alcohol or drug use disorder who then completed questions about SUD services. Results: Over 60% of women with dual alcohol and drug use disorders used some type of SUD service in the past year, while 52% with a drug only disorder, and 44% with an alcohol only disorder used services. The most mentioned barrier to service use was depression, but cost, wait time, where to find treatment, and facilities located too far away, were also frequently noted. A large proportion across all groups indicated high motivation for treatment and willingness to discuss their SUD in a primary care setting. Conclusion: There are continued barriers to SUD service use for homeless women despite high motivation for treatment, and willingness to be asked about SUD and mental health problems in primary care. HCH primary care sites should more systematically ask about SUD and mental health issues and address women’s expressed need for support groups and alternative therapies to more holistically address their SUD needs.     

Local spatial clustering in youths’ use of tobacco,alcohol, and marijuana in Boston

ABSTRACT

Background: Understanding geographic variation in youth drug use is important for both identifying etiologic factors and planning prevention interventions. However, little research has examined spatial clustering of drug use among youths by using rigorous statistical methods. Objectives: The purpose of this study was to examine spatial clustering of youth use of tobacco, alcohol, and marijuana. Methods: Responses on tobacco, alcohol, and marijuana use from 1,292 high school students ages 13–19 who provided complete residential addresses were drawn from the 2008 Boston Youth Survey Geospatial Dataset. Response options on past month use included “none,” “1–2,” “3–9,” and “10 or more.” The response rate for each substance was approximately 94%. Spatial clustering of youth drug use was assessed using the spatial Bernoulli model in the SatScan? software package. Results: Approximately 12%, 36%, and 18% of youth reported any past-month use of tobacco, alcohol, and/or marijuana, respectively. Two clusters of elevated past tobacco use among Boston youths were generated, one of which was statistically significant. This cluster, located in the South Boston neighborhood, had a relative risk of 5.37 with a p-value of 0.00014. There was no significant localized spatial clustering in youth past alcohol or marijuana use in either the unadjusted or adjusted models. Conclusion: Significant spatial clustering in youth tobacco use was found. Finding a significant cluster in the South Boston neighborhood provides reason for further investigation into neighborhood characteristics that may shape adolescents' substance use behaviors. This type of research can be used to evaluate the underlying reasons behind spatial clustering of youth substance and to target local drug abuse prevention interventions and use.

Vasoconstrictor use in liver transplantation: is there evidence for rational use?

Liver transplantation is a challenging surgical operation performed in recipients with major hemodynamic perturbations related to portal hypertension. The pathophysiologic alterations in portal hypertension include a hyperdynamic circulation and decline in systemic vascular resistance and mean arterial pressure. Cardiac function can also be depressed due to cirrhosis related cardiomyopathy. These cirrhosis related changes often lead to a tenuous state in which organ perfusion is threatened and declines rapidly in the setting of many other insults including blood loss, infection, and use of medications which can cause a decline in blood pressure. This can result in renal failure as well as reduced perfusion of other organs. Additionally, direct consequences of portal hypertension include risk of bleeding from porto-systemic collaterals both in the gastrointestinal tract as well as during abdominal dissection in liver transplantation. In this milieu the management of hemodynamic alterations during liver transplant surgery is a daunting task. Recent approaches have utilized various vasoconstrictor therapies along with judicious use of intravenous fluids to maintain systemic pressures and organ perfusion. Added advantages of this approach include the potential for reducing portal pressure and thus the severity of intra-abdominal hemorrhage during surgery as well as potentially increasing renal blood flow and reducing mesenteric hyperemia. Avoidance of liberal fluid use to maintain systemic pressures also has the advantage of reducing the severity of pulmonary edema and risk of reintubation or prolonged intubation after surgery. Although these approaches utilizing vasoconstrictors are promising, many questions remain. Randomized controlled trials like those performed in the pretransplant population are sparse in the setting of liver transplantation. The optimal vasoconstrictors including combinations and doses have not been defined. Most of the benefits demonstrated thus far have been surrogate outcomes such as reduced transfusion requirement, decreased need for reintubation and improved systemic hemodynamics and reduced portal pressures during surgery. There may be different outcomes of these approaches in patients with varying severities of liver disease. The safety of minimization of fluids, along with vasoconstrictor therapy during liver transplantation has been questioned in patients with higher risk of renal failure including recipients with high MELD scores. Other factors besides disease severity, including organ quality and cold ischemia times, need to be accounted for in future trials. Optimal outcomes including postoperative patient and graft survival, hospital stay and renal function should also be incorporated in future trials of vasoconstrictor therapy during liver transplantation.     

The use of opioids in the treatment of osteoarthritis: When, why, and how?

As life expectancy increases every decade, the incidence and prevalence of osteoarthritis (OA) also will increase. Despite progress in our knowledge of the pathophysiology of OA, the management of OA-mediated pain continues to challenge physicians. Concern regarding the cardiovascular effects of cyclooxygenase-2 inhibitors and the gastrointestinal and renal side effects of nonsteroidal anti-inflammatory drugs (NSAIDs) in general has limited the use of these medications in the management of chronic non-cancer pain. Appropriately dosed and monitored use of opioids for OA pain, when more conservative methods have failed, has potentially fewer life-threatening complications associated with it than the more commonly and often less successfully employed pharmacotherapeutic approaches to care. When used as part of a multimodal approach to pain control, opioids are a safe and effective treatment for joint pain, including that of OA. Patients for whom NSAIDs are contraindicated, or for whom combined acetaminophen, tramadol, and NSAID therapy is ineffective, may be started on low-dose opioids and titrated as needed and tolerated. Patient education and informed consent, exercise, complementary medicine, and the use of a controlled substance agreement increases the likelihood of patient compliance with treatment guidelines, improving functional capacity and quality of life.     

Does the use of HIV testing and counseling services influence condom use among low-paid female sex workers in Guangxi,China?

HIV testing and counseling (HTC) are increasingly used in China during routine medical care visits to health facilities. However, limited data are available regarding the association between the utilization of HTC services and condom use among low-paid female sex workers (FSWs) who are at high risk of HIV infection but are hard to reach. A cross-sectional study was conducted among 794 low-paid FSWs in a city of Guangxi Zhuang Autonomous Region in 2011. Results showed that 71.7% of low-paid FSWs had utilized HTC services in the previous year and 65.7% reported having used a condom during the last sexual intercourse with their clients. Multivariate logistic regression analysis showed that utilizing HTC services was significantly and positively associated with the condom use. It also indicated that low-paid FSWs who were older, married, had higher education, earned less money, had high number of clients, had a history of sexually transmitted diseases, or had little or no HIV knowledge were less likely to use a condom during the last sexual encounter. The study suggests that HTC services need to be scaled up and made more accessible for this vulnerable population.     

Internet use by patients--a shift in power?

Traditionally, the patient has relied on health care professionals for advice and knowledge. The unprecedented access to information offered by the Internet may challenge this relationship. To investigate this, a questionnaire was sent to 640 transplant patients. 24 responded positively and were interviewed to see if the information they found on the net had been useful, in negotiating a change in treatment or as support. Internet use was associated with younger males who had access to the net at work. 22 had found useful information although only 1 patient had negotiated a change in treatment as a result. As the Internet becomes universally available, patients will be empowered to have a larger role in maintaining their health, and support groups will be better able to help patients. To prepare to deal with this avalanche of information we need to develop a system of accreditation of Internet sites, to create our own sites and to collaborate with patient support groups.     

Are hip protectors correctly positioned in use?

There are many designs of hip protectors ranging from small elliptical shaped hard shell designs to large circular soft pads. They are held in position usually by being contained in a close fitting pocket on a garment that patients wear all the time they are at risk of sustaining a fracture of the hip if they fall onto the area of the greater trochanter (GT). It is important for the function of the hip protector that the pad element is positioned over the GT when the subject falls onto a surface such as the floor so as to provide the maximal protection by reducing the large forces transmitted to the femoral neck that lead to the fracture of the bone. In this study, anatomical measurements show where the GT is relevant to the centre of the hip protector, and position and movement studies have shown that generally the hard shell design of the hip protector lies posterior and proximal to the GT both for erect and flexed positions of the hip. The position of the GT relevant to the anterior superior iliac crest was established using ultrasound examinations on control and patients admitted with a fracture of the hip due to a fall. The diagonal surface distance for the three groups of test subjects was approximately 12 cm and a template was developed that could be used to locate the GT. A 'zone' of GT position and movement has been established relative to the anterior superior iliac crest, and designers of garments should ensure that this zone is within the area of protection provided by their hip protector pad design.     

Intra-household mosquito net use in Ethiopia, Ghana, Mali, Nigeria, Senegal, and Zambia: are nets being used? Who in the household uses them?

Mosquito net ownership is rising in sub-Saharan Africa but will substantially reduce malaria only if nets are used and the most vulnerable household members sleep under them. We used data from 9 large-scale household surveys conducted in 6 African countries from 2000 to 2004 that enumerated all household members and nets owned, analyzing only net-owning households. Across countries, women of reproductive age and children under 5 (without gender bias) were most likely to use the net; least likely were children of age 5-14 and adult males. Nets commonly covered 2-3 people. If a baby net was used, fewer people used the family net. Pregnant women were more likely to use a net in 2004 than in 2000. In several countries, a sizable minority of nets owned were not used. Understanding intra-household net-use patterns helps malaria control programs more effectively direct their efforts to increase their public health impact.     

Progression of a general substance use pattern among adolescents in Switzerland? Investigating the relationship between alcohol, tobacco, and cannabis use over a 12-year period

Many studies have shown that different risk or problem behaviors in adolescence are interrelated. Given the increased use of various substances among adolescents in the United States and in most European countries, the question emerges whether there are more substance use "specialists" or a progression of a general substance use pattern. If the latter is the case, the interrelatedness of the different substances should remain stable over time in a representative sample and among subgroups characterized by gender and language. Data from 4,146 15-year-olds in Switzerland surveyed in 1986, 1994 and 1998 were analyzed, using confirmatory factor analyses based on polychoric correlations. Smoking, drunkenness and cannabis use greatly increased over the 12-year period. However, in the different survey years, the factor structure did not differ for all 15-year-olds in general or for subgroups. This progression of a general pattern refers to an increased normalization of recreational substance use in general, not only of cannabis use. Favorable attitudes towards general substance use are a challenge to substance use prevention in adolescence, and reveal a need for more research on such a progression in other countries.     

Racial and ethnic disparities in the use of health services: bias,preferences, or poor communication?

African Americans and Latinos use services that require a doctor's order at lower rates than do whites. Racial bias and patient preferences contribute to disparities, but their effects appear small. Communication during the medical interaction plays a central role in decision making about subsequent interventions and health behaviors. Research has shown that doctors have poorer communication with minority patients than with others, but problems in doctor-patient communication have received little attention as a potential cause, a remediable one, of health disparities. We evaluate the evidence that poor communication is a cause of disparities and propose some remedies drawn from the communication sciences.
