Urinalysis-Assessed and Self-Reported Substance Use as Correlates of Multiple Indicators of Suicide Risk Among Acute Care Psychiatric Inpatients.

Nonalcohol substance use is a robust correlate of suicide risk. However, few data exist regarding the degree to which nonalcohol substance use, as measured by objective indicators (e.g., urinalysis toxicology screen), is related to suicide risk. This study examined the associations of a multimodal assessment of nonalcohol substance use and multiple indicators of suicide risk. Overall, 168 acute care psychiatric inpatients participated and provided data spanning urinalysis toxicology screen and self-report instruments. Substance use per urinalysis toxicology screen and self-report was not related to current suicidal ideation severity. However, substance use per urinalysis toxicology screen was significantly associated with a suicide attempt history and suicidality as a primary reason for admission. Substance use is an important variable to consider in suicide risk conceptualization. Findings underscore the importance of leveraging, when possible, objective indicators of substance use (e.g., urinalysis toxicology screen) in suicide risk formulations.

Evaluation of satisfaction with three different cervical cancer screening modalities: clinician-collected Pap test vs. HPV test by self-sampling vs. HPV test by urine sampling.

OBJECTIVE: Human papillomavirus testing by self-sampling and urine sampling might be alternatives to Papanicolaou test (Pap test) for cervical cancer screening (CCS), and may increase compliance and adherence thereto. The present study aimed to explore satisfaction and preferences for cervical screening modalities among Korean women. METHODS: In total, 732 women aged between 20 and 69 years responded to a questionnaire designed to survey the women's perceived satisfaction for the 3 CCS modalities: clinician-collected Pap test, self-collected vaginal sampling (self-sampling) and urine sampling. RESULTS: Overall satisfaction was significantly higher with both the self-sampling and urine sampling than the clinician-collected Pap test (odds ratio [OR]=2.01; 95% confidence interval [CI]=1.48-3.00 and OR=2.47; 95% CI=1.75-3.48, respectively). Psychological distress, including embarrassment, pain, anxiety, discomfort, and stress, with self-sampling and urine sampling were significantly lower than that with the Pap test. 52% of participants reported preferences for self-sampling in the next screening round. CONCLUSIONS: Korean women were more likely to report satisfaction with alternative modalities (self-sampling and urine sampling) for CCS in comparison to the Pap test. This suggests that self-collected modalities may help with improving CCS uptake rates by eliminating burden related with the Pap test. However, further studies for test accuracy and cost-effective analysis of the alternative modalities should be conducted in order to apply CCS.

Resident Physician Knowledge of Urine Testing and Treatment Over Four Years.

We surveyed resident physicians at 2 academic medical centers regarding urinary testing and treatment as they progressed through training. Demographics and self-reported confidence were compared to overall knowledge using clinical vignette-based questions. Overall knowledge was 40% in 2011 and increased to 48%, 55%, and 63% in subsequent years (P<.001).Infect Control Hosp Epidemiol 2018;39:616-618.

Denial of urinalysis-confirmed opioid use in prescription opioid dependence.

Although research has generally supported the validity of substance use self-reports, some patients deny urine-verified substance use. We examined the prevalence and patterns of denying urinalysis-confirmed opioid use in a sample of prescription opioid dependent patients. We also identified characteristics associated with denial in this population of increasing public health concern. Opioid use self-reports were compared with weekly urinalysis results in a 12-week multi-site treatment study for prescription opioid dependence. Among those who used opioids during the trial (n=246/360), 44.3% (n=109) denied urinalysis-confirmed opioid use, although usually only once (78%). Overall, 22.9% of opioid-positive urine tests (149/650) were denied on self-report. Multivariable analysis found that initially using opioids to relieve pain was associated with denying opioid use. These findings support the use of both self-reports and urine testing in treating prescription opioid dependence.

Does self monitoring of blood glucose as opposed to urinalysis provide additional benefit in patients newly diagnosed with type 2 diabetes receiving structured education? The DESMOND SMBG randomised controlled trial protocol.

BACKGROUND: The benefit of self-monitoring of blood glucose (SMBG) in people with type 2 diabetes on diet or oral agents other than sulphonylureas remains uncertain. Trials of interventions incorporating education about self-monitoring of blood glucose have reported mixed results. A recent systematic review concluded that SMBG was not cost-effective. However, what was unclear was whether a cheaper method of self-monitoring (such as urine glucose monitoring) could produce comparable benefit and patient acceptability for less cost. METHODS/DESIGN: The DESMOND SMBG trial is comparing two monitoring strategies (blood glucose monitoring and urine testing) over 18 months when incorporated into a comprehensive self-management structured education programme. It is a multi-site cluster randomised controlled trial, conducted across 8 sites (7 primary care trusts) in England, UK involving individuals with newly diagnosed Type 2 diabetes.The trial has 80% power to demonstrate equivalence in mean HbA1c (the primary end-point) at 18 months of within ± 0.5% assuming 20% drop out and 20% non-consent. Secondary end-points include blood pressure, lipids, body weight and psychosocial measures as well as a qualitative sub-study.Practices were randomised to one of two arms: participants attend a DESMOND programme incorporating a module on self-monitoring of either urine or blood glucose. The programme is delivered by accredited educators who received specific training about equipoise. Biomedical data are collected and psychosocial scales completed at baseline, and 6, 12, and 18 months post programme. Qualitative research with participants and educators will explore views and experiences of the trial and preferences for methods of monitoring. DISCUSSION: The DESMOND SMBG trial is designed to provide evidence to inform the debate about the value of self-monitoring of blood glucose in people with newly diagnosed type 2 diabetes. Strengths include a setting in primary care, a cluster design, a health economic analysis, a comparison of different methods of monitoring while controlling for other components of training within the context of a quality assured structured education programme and a qualitative sub-study.

Performance evaluation of a new rapid urine test for chlamydia in men: prospective cohort study.

OBJECTIVE: To evaluate the performance of a rapid test for chlamydia with first void male urine samples as a potential tool for diagnosis and screening of chlamydial infection in men. DESIGN: Evaluation of test performance in prospective cohort study. Settings A young people's sexual health centre (site 1) and a genitourinary medicine clinic (site 2) in the United Kingdom. PARTICIPANTS: 1211 men aged 16-73 attending either of the two sites. MAIN OUTCOME MEASURES: Sensitivity, specificity, positive predictive value, and negative predictive value of the Chlamydia Rapid Test versus polymerase chain reaction assay. Relation between the visual signal of the Chlamydia Rapid Test and organism load. RESULTS: Detection rates for Chlamydia trachomatis infection with polymerase chain reaction were 4.4% (20/454) at site 1 and 11.9% (90/757) at site 2. Compared with polymerase chain reaction assay, the resolved sensitivity, specificity, positive predictive value, and negative predictive value of the Chlamydia Rapid Test was 82.6% (90/109), 98.5% (1085/1102), 84.1% (90/107), and 98.3% (1085/1104), respectively. The organism load in first void urine samples that were positive for chlamydia ranged from 7.28x10(2) to 6.93x10(6) plasmids/ml and correlated significantly with the visual signal of the Chlamydia Rapid Test (r=0.7897, P<0.001). CONCLUSIONS: The performance of the new Chlamydia Rapid Test with first void male urine samples indicates that it would be an effective diagnostic tool for chlamydial infection in men. The availability of test results within an hour allows for immediate treatment and contact tracing, potentially reducing the risks of persistent infection and onward transmission. The test could also provide a simple and reliable alternative to nucleic acid amplification assays for testing of male urine in chlamydial screening programmes in high prevalence settings.

A questionnaire on factors influencing children's assent and dissent to non-therapeutic research.

BACKGROUND: Knowledge about assent or dissent of children to non-therapeutic research is poor. OBJECTIVES: To assess sociodemographic characteristics in healthy children and adolescents who were invited to participate in non-therapeutic research, to evaluate their motives for assent or dissent and their understanding of the information given. METHODS: A total of 1281 healthy children and adolescents six to sixteen years of age were invited to participate in a non-therapeutic study and a questionnaire. RESULTS: Assenting children were motivated by a desire to help sick children (n = 638, 98%) and to gain experience with participating in a research study (n = 503, 82%). Dissenting children made their decision because of worries about having a blood (n = 193, 46%) or a urine sample (n = 94, 26%) taken or because of worries about a doctor's examination (n = 136, 33%). Fewer children in the assent group (n = 166, 25%) than in the dissent group (136, 33%) worried about the doctor's examination (p = 0.01). In the assent and dissent group, 568 (86%) and 343 (85%) children, respectively, said they were able to understand some or all of the written information (p = 0.42), and 650 (97%) and 330 (98%), respectively, were able to understand some or all of the verbal information (p = 0.07). CONCLUSIONS: Sociodemographic characteristics may not influence healthy children's decision to volunteer for non-therapeutic research. Assenting children have altruistic and educational motives, whereas worries about procedures may cause children to dissent. A great majority of school children and adolescents feel capable of understanding and giving assent or dissent to non-therapeutic research.

Opportunistic screening for genital chlamydial infection. I: acceptability of urine testing in primary and secondary healthcare settings.

OBJECTIVES: To determine the acceptability of opportunistic screening for Chlamydia trachomatis in young people in a range of healthcare settings. DESIGN: An opportunistic screening programme (1 September 1999 to 31 August 2000) using urine samples tested by ligase chain reaction (LCR). Data on uptake and testing were collected and in-depth interviews were used for programme evaluation. SETTING: General practice, family planning, genitourinary medicine clinics, adolescent sexual health clinics, termination of pregnancy clinics, and women's services in hospitals (antenatal, colposcopy, gynaecology and infertility clinics) in two health authorities (Wirral and Portsmouth and South East Hampshire). Main participants: Sexually active women aged between 16 and 24 years attending healthcare settings for any reason. MAIN OUTCOME MEASURES: Uptake data: proportion of women accepting a test by area, healthcare setting, and age; overall population coverage achieved in 1 year. Evaluation data: participants' attitudes and views towards opportunistic screening and urine testing. RESULTS: Acceptance of testing by women (16-24 years) was 76% in Portsmouth and 84% in Wirral. Acceptance was lower in younger women (Portsmouth only) and varied by healthcare setting within each site. 50% of the target female population were screened in Portsmouth and 39% in Wirral. Both the opportunistic offer of screening and the method of screening were universally acceptable. Major factors influencing a decision to accept screening were the non-invasive nature of testing and treatment, desire to protect future fertility, and the experimental nature of the screening programme. CONCLUSIONS: An opportunistic model of urine screening for chlamydial infection is a practical, universally acceptable method of screening.

The acceptability of urinary LCR testing for Chlamydia trachomatis among participants in a probability sample survey of sexual attitudes and lifestyles.

OBJECTIVES: To examine the factors that influence respondents' willingness to participate in urinary testing for Chlamydia trachomatis in a general population feasibility survey of sexual attitudes and lifestyles. METHODS: 199 sexually experienced, 18-44 year old participants, recruited as part of a larger (n=901) methodological study of sexual attitudes and lifestyles, were invited to provide a urine sample for chlamydial infection testing using ligase chain reaction (LCR) techniques. Analysis of the survey data and in-depth qualitative interviews were undertaken to explore the factors that influenced participants' decisions to participate. RESULTS: 143/199 (72%) participants agreed to provide a urine sample. The likelihood of providing a urine sample was reduced if other individuals were present in the home at the time of interview (OR 0.42, 95% confidence interval 0.20-0.90, p=0.03). Trust and rapport with the interviewer, understanding the aims of the test, sense of obligation, and perceived importance of the test were identified as additional influencing factors in the in-depth interviews. CONCLUSIONS: Survey respondents' uncertainty or embarrassment at participating in urine testing can be overcome if they are well informed, motivated by the potential health gain, and briefed by trained and confident interviewers.
