Abstract

Purpose To compare self-reported diabetes treatments among Chinese urban residents, rural migrants in urban settings, and rural residents. Methods Data from 993 diabetics at least 45 years of age were collected from the China Health and Retirement Longitudinal Study conducted in 2011. Multiple logistic regressions were performed to examine the associations between individual characteristics and diabetes treatments. Results In total, 719/993 (72.4%) of the respondents received treatment for diabetes; of which < 8% used insulin therapy. Urban residents were more likely than rural residents to use insulin therapy [odds ratio (OR) = 0.44, confidence interval (CI): 0.20-0.99; p < 0.05], and more likely to use traditional Chinese medicine than migrants (OR = 0.30, CI: 0.10-0.96; p < 0.05). Overall, rural residents showed lower treatment rates than urban and migrant populations. Conclusion Efforts to improve and enhance diabetes treatments, particularly among rural residents, are urgently needed in China.

Abstract

This study made comparisons of self-reported functional and general health status between Chinese women and men in different age-groups in rural and urban settings and examined multiple factors relating to these health statuses in older adults. This study included a sample of 4017 respondents, aged 55 years and older, from the Hubei subsample of the Chinese National Health Service Survey III in 2003. The results illustrate that the differences in self-rated functional and general health status between genders and between urban and rural areas diminished with age. Access to health care was strongly associated with health status. The quality of the local environment, measured by access to tap water, was a significant factor for rural residents. Our study suggests that improving access to health care services and reducing environmental health risks are critical for improving physical functioning, psychological functioning, and self-rated general health for older adults in China.

Abstract

Objective Regular self-weighing, which in this article is defined as weighing oneself regularly over a period of time (e.g., daily, weekly), is recommended as a weight loss strategy. However, the published literature lacks a review of the recent evidence provided by prospective, longitudinal studies. Moreover, no paper has reviewed the psychological effects of self-weighing. Therefore, the objective is to review the literature related to longitudinal associations between self-weighing and weight change as well as the psychological outcomes. Methods Electronic literature searches in PubMed, Ovid PsycINFO, and Ebscohost CINAHL were conducted. Keywords included overweight, obesity, self-weighing, etc. Inclusion criteria included trials that were published in the past 25 years in English; participants were adults seeking weight loss treatment; results were based on longitudinal data. Results The results (N = 17 studies) revealed that regular self-weighing was associated with more weight loss and not with adverse psychological outcomes (e.g., depression, anxiety). Findings demonstrated that the effect sizes of association between self-weighing and weight change varied across studies and also that the reported frequency of self-weighing varied across studies. Conclusions The findings from prospective, longitudinal studies provide evidence that regular self-weighing has been associated with weight loss and not with negative psychological outcomes.

Abstract

Adult hospitalized patients are at risk for malnutrition. The sensitivity and specificity of screening tools were compared with Subjective Global Assessment. Methods included a systematic review using PubMed, CINAHL Plus, and EMBASE through April 2014. Study quality was assessed using the Quality Assessment of Diagnostic Accuracy Studies method. The results showed that the Malnutrition Universal Screening Tool, Nutrition Risk Screening-2002, and Malnutrition Screening Tool were most frequently tested. The specificity was generally good (>80%), but sensitivity was variable. Malnutrition Universal Screening Tool, Nutrition Risk Screening-2002, and Malnutrition Screening Tool are screening tools that consider population characteristics and risk cut points and are easy to administer. Key words: malnutrition, nutrition assessment, nutrition screening, sensitivity and specificity, subjective global assessment, undernutrition.

Abstract

Background This paper examines sexual practices, partner concurrency and sexually transmissible infections (STI)/HIV infection among male sex workers (MSWs) in Vietnam. Methods: Six hundred and fifty-four MSWs, aged 16-35 years, were recruited in Hanoi, Nha Trang and Ho Chi Minh City between 2009 and 2011. Survey measures included demographic characteristics, drug use, types of sexual partners and sexual practices. Subjects were screened for STIs, including HIV. Results: MSWs in Ho Chi Minh City (33%) were more likely than those from the other two sites to be current users of one or more types of illegal drugs (P<0.001). MSWs with both male and female elective partners (compared with other partnership types) were more likely to have anal sex with male client partners (P<0.001), elective male partners (P≤0.045) and elective female partners (P≤0.025). At last sex with a male client partner, only 30% used a condom during anal intercourse. At last sex with an elective female partner, only 31% used a condom during vaginal sex and only 3% during anal sex. Although rates of HIV are low (4%), other STIs are high, including chlamydia (17%), gonorrhoea (29%) and human papillomavirus (33%). Most (57.3%) have never been tested for HIV and only 17% have ever disclosed to a healthcare provider that they have sex with men. Conclusions: Complex patterns of sexual concurrency, coupled with high rates of STIs, signal the urgent need for health services interventions among MSWs, both to improve individual health outcomes and to reduce secondary STI/HIV transmission among sexual partner networks.

Abstract

Background: Over 50,000 individuals become infected with HIV annually in the U.S., and over a quarter of HIV infected individuals are heterosexuals. Undiagnosed HIV infection, as well as a lack of retention in care among those diagnosed, are both primary factors contributing to ongoing HIV incidence. Further, there are racial/ethnic disparities in undiagnosed HIV and engagement in care, with African Americans/Blacks and Latinos remaining undiagnosed longer and less engaged in care than Whites, signaling the need for culturally targeted intervention approaches to seek and test those with undiagnosed HIV infection, and link them to care with high retention. Methods/Design: The study has two components: one to seek out and test heterosexuals at high risk for HIV infection, and another to link those found infected to HIV care with high retention. We will recruit sexually active African American/Black and Latino adults who have opposite sex partners, negative or unknown HIV status, and reside in locations with high poverty and HIV prevalence. The "Seek and Test" component will compare the efficacy and cost effectiveness of two strategies to uncover undiagnosed HIV infection: venue-based sampling and respondent-driven sampling (RDS). Among those recruited by RDS and found to have HIV infection, a "Treat and Retain" component will assess the efficacy of a peer-driven intervention compared to a control arm with respect to time to an HIV care appointment and health indicators using a cluster randomized controlled trial design to minimize contamination. RDS initial seeds will be randomly assigned to the intervention or control arm at a 1:1 ratio and all recruits will be assigned to the same arm as the recruiter. Participants will be followed for 12 months with outcomes assessed using medical records and biomarkers, such as HIV viral load. Discussion: Heterosexuals do not test for HIV as frequently as and are diagnosed later than other risk groups. The study has the potential to contribute an efficient, innovative, and sustainable multi-level recruitment approach and intervention to the HIV prevention portfolio. Because the majority of heterosexuals at high risk are African American/Black or Latino, the study has great potential to reduce racial/ethnic disparities in HIV/AIDS. Trial registration: ClinicalTrials.gov, NCT01607541, Registered May 23, 2012.

Abstract

Elderly population account for more than 50% of all intensive care admissions, and during their stay, up to 87% of them suffer from delirium. There is a large body of evidence demonstrating increased mortality and worse cognitive function for elderly patients who become delirious during their intensive care unit stay. Although the cause of delirium is multifactorial, inappropriate and outdated sedation methods are preventable causes. We review the current best evidences and provide what we believe are the best sedation strategies that are in line with the Society of Critical Care Medicine's Pain, Agitation and Delirium best practice guideline to reduce the incidence of intensive care unit-associated delirium.

Abstract

Background: HIV research in Vietnam has focused primarily on its large heroin injector population. Data on men who have sex with men [MSM], particularly the large and growing population of men who exchange sex for money or other material rewards, male sex workers [MSWs], is very limited. Methods: Data derive from a cross-sectional study of MSW, age 16-35, recruited using community sampling methods in three cities in 2010-2011, including Hanoi, Ho Chi Minh City [HCMC], and Nha Trang City (n=710). Assessments included demographic characteristics, substance use, sexual risk, and use of health services. A series of "event" questions were used to assess the influence of alcohol and drugs on sexual risk. Results: Both tobacco and alcohol are initiated at a young age and most participants currently use both substances overall across all three cities. While alcohol and tobacco use precede the initiation of sex work, stimulant and opiate use are initiated following the initiation of sex work. There was substantial overlap between substance use and sexual risk, and this overlap was strongest in sexual events involving male and female elective partners rather than sex work clients. Conclusion: Although rates of HIV infection in this group are low, this may be an artifact of the young age of the sample. High rates of drug use, including alcohol, tobacco and illicit drugs, coupled with high rates of ulcerative STIs such as HPV, suggest the potential for rapid amplification of STI/HIV risk among MSW and their complex sex partnering networks.

Abstract

To ascertain HCV testing practices among US prisons and jails, we conducted a survey study in 2012, consisting of medical directors of all US state prisons and 40 of the largest US jails, that demonstrated a minority of US prisons and jails conduct routine HCV testing. Routine voluntary HCV testing in correctional facilities is urgently needed to increase diagnosis, enable risk-reduction counseling and preventive health care, and facilitate evaluation for antiviral treatment.

Abstract

Breast cancer-related lymphedema is a syndrome of abnormal swelling coupled with multiple symptoms resulting from obstruction or disruption of the lymphatic system associated with cancer treatment. Research has demonstrated that with increased number of symptoms reported, breast cancer survivors’ limb volume increased. Lymphedema symptoms in the affected limb may indicate a latent stage of lymphedema in which changes cannot be detected by objective measures. The latent stage of lymphedema may exist months or years before overt swelling occurs. Symptom report may play an important role in detecting lymphedema in clinical practice. The purposes of this study were to: 1) examine the validity, sensitivity, and specificity of symptoms for detecting breast cancer-related lymphedema and 2) determine the best clinical cutoff point for the count of symptoms that maximized the sum of sensitivity and specificity. Data were collected from 250 women, including healthy female adults, breast cancer survivors with lymphedema, and those at risk for lymphedema. Lymphedema symptoms were assessed using a reliable and valid instrument. Validity, sensitivity, and specificity were evaluated using logistic regression, analysis of variance, and areas under receiver operating characteristic curves. Count of lymphedema symptoms was able to differentiate healthy adults from breast cancer survivors with lymphedema and those at risk for lymphedema. A diagnostic cutoff of three symptoms discriminated breast cancer survivors with lymphedema from healthy women with a sensitivity of 94% and a specificity of 97% (area under the curve =0.98). A diagnostic cutoff of nine symptoms discriminated at-risk survivors from survivors with lymphedema with a sensitivity of 64% and a specificity of 80% (area under the curve =0.72). In the absence of objective measurements capable of detecting latent stages of lymphedema, count of symptoms may be a cost-effective initial screening tool for detecting lymphedema.

Abstract

Innovative interventions increasing linkage, adherence, and retention in care among HIV-infected persons in the criminal justice system are needed. The authors conducted a qualitative study to investigate technology-based tools to facilitate linkage to community-based care and viral suppression for HIV-infected jail detainees on antiretroviral medications being released to the community. The authors conducted 24 qualitative interviews - 12 in Rhode Island and 12 in Washington, DC - among recently incarcerated HIV-infected persons to elicit their perceptions on the use of technology tools to support linkage to HIV care among criminal justice populations. This article discusses participants' perceptions of the acceptability of technological tools such as (a) a computer-based counseling and (b) text messaging interventions. The participants reported positive experiences when previewing the technology-based tools to facilitate linkage to HIV care and adherence to HIV medications. Successful linkage to care has been shown to improve HIV-associated and non-HIV-associated health outcomes, as well as prevent criminal recidivism and facilitate reentrants' successful and meaningful transition. These findings can be used to inform the implementation of interventions aimed at promoting adherence to antiretroviral medications and linkage to care for HIV-infected persons being released from the correctional setting.

Abstract

BACKGROUND: The US Preventive Services Task Force recommends screening for and treating obesity. However, there are many barriers to successfully treating obesity in primary care (PC). Technology-assisted weight loss interventions offer novel ways of improving treatment, but trials are overwhelmingly conducted outside of PC and may not translate well into this setting. We conducted a systematic review of technology-assisted weight loss interventions specifically tested in PC settings. METHODS: We searched the literature from January 2000 to March 2014. Inclusion criteria: (1) Randomized controlled trial; (2) trials that utilized the Internet, personal computer, and/or mobile device; and (3) occurred in an ambulatory PC setting. We applied the Cochrane Effective Practice and Organization of Care (EPOC) and Delphi criteria to assess bias and the Pragmatic-Explanatory Continuum Indicator Summary (PRECIS) criteria to assess pragmatism (whether trials occurred in the real world versus under ideal circumstances). Given heterogeneity, results were not pooled quantitatively. RESULTS: Sixteen trials met inclusion criteria. Twelve (75 %) interventions achieved weight loss (range: 0.08 kg – 5.4 kg) compared to controls, while 5–45 % of patients lost at least 5 % of baseline weight. Trial duration and attrition ranged from 3–36 months and 6–80 %, respectively. Ten (63 %) studies reported results after at least 1 year of follow-up. Interventions used various forms of personnel, technology modalities, and behavior change elements; trials most frequently utilized medical doctors (MDs) (44 %), web-based applications (63 %), and self-monitoring (81 %), respectively. Interventions that included clinician-guiding software or feedback from personnel appeared to promote more weight loss than fully automated interventions. Only two (13 %) studies used publically available technologies. Many studies had fair pragmatism scores (mean: 2.8/4), despite occurring in primary care. DISCUSSION: Compared to usual care, technology-assisted interventions in the PC setting help patients achieve weight loss, offering evidence-based options to PC providers. However, best practices remain undetermined. Despite occurring in PC, studies often fall short in utilizing pragmatic methodology and rarely provide publically available technology. Longitudinal, pragmatic, interdisciplinary, and open-source interventions are needed.

Abstract

Background • Female infertility is a complex issue encompassing a wide variety of diagnoses, many of which are caused or affected by adhesions. Objectives • The study intended to examine the rates of successful treatment of infertile women using a protocol of manual physical therapy to address underlying adhesive disease leading to infertility. Methods • The research team designed a retrospective chart review. Setting • The study took place in a private physical therapy clinic. Participants • Participants were 1392 female patients who were treated at the clinic between the years of 2002 and 2011. They had varying diagnoses of infertility, including occluded fallopian tubes, hormonal dysfunction, and endometriosis, and some women were undergoing in vitro fertilization (IVF). Intervention • All patients underwent whole-body, patientcentered treatments that used a protocol of manual physical therapy, which focused on restoring mobility and motility to structures affecting reproductive function. Outcome Measures • Improvements demonstrated in the condition(s) causing infertility were measured by improvements in tubal patency and/or improved hormone levels or by pregnancy. Results • The results included a 60.85% rate of clearing occluded fallopian tubes, with a 56.64% rate of pregnancy in those patients. Patients with endometriosis experienced a 42.81% pregnancy rate. The success rate was 49.18% for lowering elevated levels of follicle stimulating hormone (FSH), with a 39.34% pregnancy rate in that group, and 53.57% of the women with polycystic ovarian syndrome (PCOS) achieved pregnancy. The reported pregnancy rate for patients who underwent IVF after the therapy was 56.16%. The results also suggested that the treatment was effective for patients with premature ovarian failure (POF). Conclusion • The manual physical therapy represented an effective, conservative treatment for women diagnosed as infertile due to mechanical causes, independent of the specific etiology.

Abstract

The nurse practitioner（NP） movement started 50 years ago in the United States. From the beginning there have been challenges and barriers to full practice authority. Changes in health care needs of the population and demographics of health care providers and particularly physicians in primary care, has created opportunities for NPs to expand their role as advanced practice nurses to increase access to care for many underserved populations, to improve patient outcomes, and to demonstrate that NPs provide high quality of care in an efficient manner. Research studies have demonstrated the effectiveness of NP managed care and data from these studies has historically helped to move the NP movement forward and effect changes in education, policy, legislation, and ultimately practice. This paper provides a brief overview of past and present research related to the NP role with recommendations from national NP groups for future priority areas for research.

Abstract

Background Although self-management approaches have shown strong evidence of positive outcomes for urinary incontinence prevention and management, few programs have been developed for Korean rural communities. Objectives This pilot study aimed to develop, implement, and evaluate a urinary incontinence self-management program for community-dwelling women aged 55 and older with urinary incontinence in rural South Korea. Methods This study used a one-group pre- post-test design to measure the effects of the intervention using standardized urinary incontinence symptom, knowledge, and attitude measures. Seventeen community-dwelling older women completed weekly 90-min group sessions for 5 weeks. Descriptive statistics and paired t-tests and were used to analyze data. Results The mean of the overall interference on daily life from urine leakage (pre-test: M = 5.76 ± 2.68, post-test: M = 2.29 ± 1.93, t = -4.609, p < 0.001) and the sum of International Consultation on Incontinence Questionnaire scores (pre-test: M = 11.59 ± 3.00, post-test: M = 5.29 ± 3.02, t = -5.881, p < 0.001) indicated significant improvement after the intervention. Improvement was also noted on the mean knowledge (pre-test: M = 19.07 ± 3.34, post-test: M = 23.15 ± 2.60, t = 7.550, p < 0.001) and attitude scores (pre-test: M = 2.64 ± 0.19, post-test: M = 3.08 ± 0.41, t = 5.150, p < 0.001). Weekly assignments were completed 82.4% of the time. Participants showed a high satisfaction level (M = 26.82 ± 1.74, range 22-28) with the group program. Conclusions Implementation of a urinary incontinence self-management program was accompanied by improved outcomes for Korean older women living in rural communities who have scarce resources for urinary incontinence management and treatment. Urinary incontinence self-management education approaches have potential for widespread implementation in nursing practice.

Abstract

A systematic review was conducted to evaluate the effectiveness of qigong as a treatment for chronic pain. Five electronic databases were searched from their date of establishment until July 2014. The review included 10 randomized clinical trials (RCTs) that compared the impacts of qigong on chronic pain with waiting list or placebo or general care. Random effect models and standard mean differences were used to present pain scores. A total of 10 RCTs met inclusion criteria. There was a statistically significant difference on reducing chronic pain between internal qigong and control (SMD: -1.23 95% CI=-2.23, -0.24 p=0.02), external qigong and general care (SMD: -1.53 95% CI=-2.15,-0.91 p<0.05), external qigong and placebo (SMD: -0.51 95% CI=-0.95,-0.06p=0.03), and internal qigong for chronic neck pain at 6 months (SMD: -1.00 95% CI=-1.94,-0.06 p=0.04). The differences between external qigong and control, external qigong and waiting list, internal qigong and waiting list, and external for premenstrual syndromes were not significant. This study showed that internal qigong generated benefits on treating some chronic pain with significant differences. External qigong showed nonsignificant differences in treating chronic pain. Higher quality randomized clinical trials with scientific rigor are needed to establish the effectiveness of qigong in reducing chronic pain.

Abstract

IntroductionSurvivors of critical illness face many potential long-term sequelae. Prior studies showed that early rehabilitation in the intensive care unit (ICU) reduces physical impairment and decreases ICU and hospital length of stay (LOS). However, these studies are based on a single ICU or were conducted with a small subset of all ICU patients. We examined the effect of an early rehabilitation program concurrently implemented in multiple ICUs on ICU and hospital LOS.MethodsAn early rehabilitation program was systematically implemented in five ICUs at the sites of two affiliated academic institutions. We retrospectively compared ICU and hospital LOS in the year before (1/2011-12/2011) and after (1/2012-12/2012) implementation.ResultsIn the pre- and post-implementation periods, respectively, there were a total of 3945 and 4200 ICU admissions among the five ICUs. After implementation, there was a significant increase in the proportion of patients who received more rehabilitation treatments during their ICU stay (p p p p ConclusionsA multi-ICU, coordinated implementation of an early rehabilitation program markedly increased rehabilitation treatments in the ICU and was associated with reduced ICU and hospital LOS as well as increased ICU admissions.

Abstract

Background: Clinical decision support systems (CDSSs) at the point of care are evidence-based interventions that have demonstrated incremental positive impact on quality of healthcare delivery over the past two decades. Existing best practices inform strategies to promote adoption and achievement of targeted outcomes. The purpose of this improvement project was to conduct a pilot implementation to understand the contextual factors and readiness for dissemination of a newly acquired electronic CDSS by evaluating its influence on diagnostic accuracy in nurse practitioners (NPs) functioning in a community health setting. Aims: The specific aims of this project were to measure and compare diagnostic accuracy in a pilot group before and after CDSS use, educate clinicians about the system and pilot its use, and then leverage the experience to design the practice-wide CDSS dissemination strategy. Methods: The project engaged a subset of NPs from a home-based primary care practice and other organizational stakeholders who provided tangible support and necessary resources for successful adoption of this innovation in practice. A structured conceptual model of Evidence-Based Practice Improvement enhanced with elements of the Promoting Action on Research Implementation in Health Sciences framework was used to guide the development, implementation and evaluation of this practice improvement initiative. A group of seven NP representatives of the practice participated in the project. Data collection was composed of small tests of change (plan-do-study-act) cycles at the local practice level, measuring achievement of improvement of the chosen outcome of correctness of medical diagnosis evidenced by appropriate substantiating clinical documentation. Linking evidence to action: In this home visiting primary care practice setting, use of a CDSS by NPs achieved eventual improvement in diagnostic accuracy and clinical documentation, as demonstrated on chart audit, though the improvement was not sustained over time. The pilot findings ultimately informed decision making about CDSS dissemination strategies and future uses of the system. When appropriately deployed, a CDSS offers the potential to improve professional practice, support differential diagnosis and evidence-based treatment, and provide detailed information about the disease state to facilitate robust clinical documentation.
