Psychosocial interventions to reduce alcohol consumption in concurrent problem alcohol and illicit drug users.

BACKGROUND: Problem alcohol use is common among people who use illicit drugs (PWID) and is associated with adverse health outcomes. It is also an important factor contributing to a poor prognosis among drug users with hepatitis C virus (HCV) as it impacts on progression to hepatic cirrhosis or opioid overdose in PWID. OBJECTIVES: To assess the effectiveness of psychosocial interventions to reduce alcohol consumption in PWID (users of opioids and stimulants). SEARCH METHODS: We searched the Cochrane Drugs and Alcohol Group trials register, the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, Embase, CINAHL, and PsycINFO, from inception up to August 2017, and the reference lists of eligible articles. We also searched: 1) conference proceedings (online archives only) of the Society for the Study of Addiction, International Harm Reduction Association, International Conference on Alcohol Harm Reduction and American Association for the Treatment of Opioid Dependence; and 2) online registers of clinical trials: Current Controlled Trials, ClinicalTrials.gov, Center Watch and the World Health Organization International Clinical Trials Registry Platform. SELECTION CRITERIA: We included randomised controlled trials comparing psychosocial interventions with other psychosocial treatment, or treatment as usual, in adult PWIDs (aged at least 18 years) with concurrent problem alcohol use. DATA COLLECTION AND ANALYSIS: We used the standard methodological procedures expected by Cochrane. MAIN RESULTS: We included seven trials (825 participants). We judged the majority of the trials to have a high or unclear risk of bias.The psychosocial interventions considered in the studies were: cognitive-behavioural coping skills training (one study), twelve-step programme (one study), brief intervention (three studies), motivational interviewing (two studies), and brief motivational interviewing (one study). Two studies were considered in two comparisons. There were no data for the secondary outcome, alcohol-related harm. The results were as follows.Comparison 1: cognitive-behavioural coping skills training versus twelve-step programme (one study, 41 participants)There was no significant difference between groups for either of the primary outcomes (alcohol abstinence assessed with Substance Abuse Calendar and breathalyser at one year: risk ratio (RR) 2.38 (95% confidence interval [CI] 0.10 to 55.06); and retention in treatment, measured at end of treatment: RR 0.89 (95% CI 0.62 to 1.29), or for any of the secondary outcomes reported. The quality of evidence for the primary outcomes was very low.Comparison 2: brief intervention versus treatment as usual (three studies, 197 participants)There was no significant difference between groups for either of the primary outcomes (alcohol use, measured as scores on the Alcohol Use Disorders Identification Test (AUDIT) or Alcohol, Smoking and Substance Involvement Screening Test (ASSIST) at three months: standardised mean difference (SMD) 0.07 (95% CI -0.24 to 0.37); and retention in treatment, measured at three months: RR 0.94 (95% CI 0.78 to 1.13), or for any of the secondary outcomes reported. The quality of evidence for the primary outcomes was low.Comparison 3: motivational interviewing versus treatment as usual or educational intervention only (three studies, 462 participants)There was no significant difference between groups for either of the primary outcomes (alcohol use, measured as scores on the AUDIT or ASSIST at three months: SMD 0.04 (95% CI -0.29 to 0.37); and retention in treatment, measured at three months: RR 0.93 (95% CI 0.60 to 1.43), or for any of the secondary outcomes reported. The quality of evidence for the primary outcomes was low.Comparison 4: brief motivational intervention (BMI) versus assessment only (one study, 187 participants)More people reduced alcohol use (by seven or more days in the past month, measured at six months) in the BMI group than in the control group (RR 1.67; 95% CI 1.08 to 2.60). There was no difference between groups for the other primary outcome, retention in treatment, measured at end of treatment: RR 0.98 (95% CI 0.94 to 1.02), or for any of the secondary outcomes reported. The quality of evidence for the primary outcomes was moderate.Comparison 5: motivational interviewing (intensive) versus motivational interviewing (one study, 163 participants)There was no significant difference between groups for either of the primary outcomes (alcohol use, measured using the Addiction Severity Index-alcohol score (ASI) at two months: MD 0.03 (95% CI 0.02 to 0.08); and retention in treatment, measured at end of treatment: RR 17.63 (95% CI 1.03 to 300.48), or for any of the secondary outcomes reported. The quality of evidence for the primary outcomes was low. AUTHORS' CONCLUSIONS: We found low to very low-quality evidence to suggest that there is no difference in effectiveness between different types of psychosocial interventions to reduce alcohol consumption among people who use illicit drugs, and that brief interventions are not superior to assessment-only or to treatment as usual. No firm conclusions can be made because of the paucity of the data and the low quality of the retrieved studies.

Screening for gestational diabetes mellitus in primary versus secondary care: The clinical outcomes of a randomised controlled trial.

AIMS: To examine the clinical outcomes of screening for gestational diabetes mellitus (GDM) in primary care versus secondary care, in the Irish healthcare system. DESIGN AND METHODS: A parallel group randomised controlled trial (RCT) of screening for GDM in primary versus secondary care was used to examine (i) prevalence, (ii) gestational week of screen, (iii) time to access specialist care, and (iv) maternal and neonatal outcomes. In total 781 women were recruited for screening in primary care (n=391) or secondary care (n=390). RESULTS: The prevalence of GDM and gestational week of screen were similar in both locations. There was a trend towards a longer time to access diabetes care in primary care (24days) versus secondary care (19days), a difference of 5days (p=0.09). Women screened in primary care also showed a trend towards a higher rate of large for gestational age (LGA) infants (20%) than those screened in secondary care (14.7%), (p=0.09). There were no differences between groups in maternal outcomes. CONCLUSIONS: This RCT suggests that screening for GDM in secondary care may be associated with potentially faster time to access specialist antenatal diabetes care and possibly lower LGA rates. Further research is needed to clarify these findings and to improve the delay in accessing specialist care requires an urgent focus. Further research is needed to test these findings in other health systems.

The cost-effectiveness of screening for gestational diabetes mellitus in primary and secondary care in the Republic of Ireland.

AIMS/HYPOTHESIS: The aim of the study was to assess the cost-effectiveness of screening for gestational diabetes mellitus (GDM) in primary and secondary care settings, compared with a no-screening option, in the Republic of Ireland. METHODS: The analysis was based on a decision-tree model of alternative screening strategies in primary and secondary care settings. It synthesised data generated from a randomised controlled trial (screening uptake) and from the literature. Costs included those relating to GDM screening and treatment, and the care of adverse outcomes. Effects were assessed in terms of quality-adjusted life years (QALYs). The impact of the parameter uncertainty was assessed in a range of sensitivity analyses. RESULTS: Screening in either setting was found to be superior to no screening, i.e. it provided for QALY gains and cost savings. Screening in secondary care was found to be superior to screening in primary care, providing for modest QALY gains of 0.0006 and a saving of €21.43 per screened case. The conclusion held with high certainty across the range of ceiling ratios from zero to €100,000 per QALY and across a plausible range of input parameters. CONCLUSIONS/INTERPRETATION: The results of this study demonstrate that implementation of universal screening is cost-effective. This is an argument in favour of introducing a properly designed and funded national programme of screening for GDM, although affordability remains to be assessed. In the current environment, screening for GDM in secondary care settings appears to be the better solution in consideration of cost-effectiveness.

Health related quality of life two to five years after gestational diabetes mellitus: cross-sectional comparative study in the ATLANTIC DIP cohort.

BACKGROUND: There is no consensus on the effect of gestational diabetes mellitus (GDM) on health-related quality of life (HRQOL) for the mother in the short or long term. In this study we examined HRQOL in a group of women who had GDM in the index pregnancy 2 to 5 years previously and compared it to a group of women with normal glucose tolerance (NGT) in the index pregnancy during the same time period. METHODS: The sample included 234 women who met International Association of Diabetes Study Groups (IADPSG) criteria for GDM in the index pregnancy and 108 who had NGT. The sample was drawn from the ATLATIC-DIP (Diabetes In Pregnancy) cohort - a network of antenatal centers along the Irish Atlantic seaboard serving a population of approximately 500,000 people. HRQOL was measured using the visual analogue component of the EQ-5D-3 L instrument in a cross-sectional survey. RESULTS: The difference in HRQOL between GDM and NGT groups was not significant when adjusted for the effects of the covariates. HRQOL was negatively affected by increased BMI and abnormal glucose tolerance post-partum in the NGT group. Moderate alcohol consumption was positively associated with HRQOL in the NGT group only. The negative association with smoking on HRQOL was substantially higher in the GDM group. CONCLUSIONS: A diagnosis of GDM does not appear to have an adverse effect on HRQOL, 2 to 5 years after the index pregnancy. On the contrary, its diagnosis might lead to the development of coping strategies, which, consequently attenuates the adverse effect of the subsequent acquisition of abnormal glucose tolerance post-partum on HRQOL. Women whose pregnancy was affected by GDM are more susceptible to the adverse effects on HRQOL of alcohol use and tobacco smoking.

Can the Onset of Type 2 Diabetes Be Delayed by a Group-Based Lifestyle Intervention in Women with Prediabetes following Gestational Diabetes Mellitus (GDM)? Findings from a Randomized Control Mixed Methods Trial.

OBJECTIVE: To evaluate a 12-week group-based lifestyle intervention programme for women with prediabetes following gestational diabetes (GDM). DESIGN: A two-group, mixed methods randomized controlled trial in which 50 women with a history of GDM and abnormal glucose tolerance postpartum were randomly assigned to intervention (n = 24) or wait control (n = 26) and postintervention qualitative interviews with participants. MAIN OUTCOME MEASURES: Modifiable biochemical, anthropometric, behavioural, and psychosocial risk factors associated with the development of type 2 diabetes. The primary outcome variable was the change in fasting plasma glucose (FPG) from study entry to one-year follow-up. RESULTS: At one-year follow-up, the intervention group showed significant improvements over the wait control group on stress, diet self-efficacy, and quality of life. There was no evidence of an effect of the intervention on measures of biochemistry or anthropometry; the effect on one health behaviour, diet adherence, was close to significance. CONCLUSIONS: Prevention programmes must tackle the barriers to participation faced by this population; home-based interventions should be investigated. Strategies for promoting long-term health self-management need to be developed and tested.

Feasibility, acceptability and uptake rates of gestational diabetes mellitus screening in primary care vs secondary care: findings from a randomised controlled mixed methods trial.

AIMS/HYPOTHESIS: It is postulated that uptake rates for gestational diabetes mellitus (GDM) screening would be improved if offered in a setting more accessible to the patient. The aim of this study was to evaluate the proportion of uptake of GDM screening in the primary vs secondary care setting, and to qualitatively explore the providers' experiences of primary care screening provision. METHODS: This mixed methods study was composed of a quantitative unblinded parallel group randomised controlled trial and qualitative interview trial. The primary outcome was the proportion of uptake of screening in both the primary and secondary care settings. All pregnant women aged 18 years or over, with sufficient English and without a diagnosis or diabetes or GDM, who attended for their first antenatal appointment at one of three hospital sites along the Irish Atlantic seaboard were eligible for inclusion in this study. Seven hundred and eighty-one pregnant women were randomised using random permutated blocks to receive a 2 h 75 g OGTT in either a primary (n = 391) or secondary care (n = 390) setting. Semi-structured interviews were conducted with 13 primary care providers. Primary care providers who provided care to the population covered by the three hospital sites involved were eligible for inclusion. RESULTS: Statistically significant differences were found between the primary care (n = 391) and secondary care (n = 390) arms for uptake (52.7% vs 89.2%, respectively; effect size 36.5 percentage points, 95% CI 30.7, 42.4; p < 0.001), crossover (32.5% vs 2.3%, respectively; p < 0.001) and non-uptake (14.8% vs 8.5%, respectively; p = 0.005). There were no significant differences in uptake based on the presence of a practice nurse or the presence of multiple general practitioners in the primary care setting. There was evidence of significant relationship between probability of uptake of screening and age (p < 0.001). Primary care providers reported difficulties with the conduct of GDM screening, despite recognising that the community was the most appropriate location for screening. CONCLUSIONS/INTERPRETATION: Currently, provision of GDM screening in primary care in Ireland, despite its acknowledged benefits, is unfeasible due to poor uptake rates, poor rates of primary care provider engagement and primary care provider concerns.

Effectiveness of a smartphone application to promote physical activity in primary care: the SMART MOVE randomised controlled trial.

BACKGROUND: Physical inactivity is a major, potentially modifiable, risk factor for cardiovascular disease, cancer, and other chronic diseases. Effective, simple, and generalisable interventions that will increase physical activity in populations are needed. AIM: To evaluate the effectiveness of a smartphone application (app) to increase physical activity in primary care. DESIGN AND SETTING: An 8-week, open-label, randomised controlled trial in rural, primary care in the west of Ireland. METHOD: Android smartphone users >16 years of age were recruited. All participants were provided with similar physical activity goals and information on the benefits of exercise. The intervention group was provided with a smartphone app and detailed instructions on how to use it to achieve these goals. The primary outcome was change in physical activity, as measured by a daily step count between baseline and follow-up. RESULTS: A total of 139 patients were referred by their primary care health professional or self-referred. In total, 37 (27%) were screened out and 12 (9%) declined to participate, leaving 90 (65%) patients who were randomised. Of these, 78 provided baseline data (intervention = 37; control = 41) and 77 provided outcome data (intervention = 37; control = 40). The mean daily step count at baseline for intervention and control groups was 4365 and 5138 steps per day respectively. After adjusting, there was evidence of a significant treatment effect (P = 0.009); the difference in mean improvement in daily step count from week 1 to week 8 inclusive was 1029 (95% confidence interval 214 to 1843) steps per day, favouring the intervention. Improvements in physical activity in the intervention group were sustained until the end of the trial. CONCLUSION: A simple smartphone app significantly increased physical activity over 8 weeks in a primary care population.

Reasons for participation and non-participation in a diabetes prevention trial among women with prior gestational diabetes mellitus (GDM).

BACKGROUND: Gestational diabetes mellitus (GDM) is a risk factor for the development of type 2 diabetes. Lifestyle intervention can prevent progression to type 2 diabetes in high risk populations. We designed a randomised controlled trial (RCT) to evaluate the effectiveness of an established lifestyle intervention compared to standard care for delaying diabetes onset in European women with recent GDM. Recruitment into the RCT was more challenging than anticipated with only 89 of 410 (22%) women agreeing to participate. This paper identifies factors that could enhance participation of the target population in future interventions. METHODS: We hypothesised that women who agreed to participate would have higher diabetes risk profiles than those who declined, and secondly that it would be possible to predict participation on the bases of those risk factors. To test our hypothesis, we identified the subset of women for whom we had comprehensive data on diabetes risks factors 3-5 years following GDM, reducing the sample to 43 participants and 73 decliners. We considered established diabetes risk factors: smoking, daily fruit and vegetable intake, participation in exercise, family history of diabetes, glucose values and BMI scores on post-partum re-screens, use of insulin during pregnancy, and age at delivery. We also analysed narrative data from 156 decliners to further understand barriers to and facilitators of participation. RESULTS: Two factors differentiated participants and decliners: age at delivery (with women older than 34 years being more likely to participate) and insulin use during pregnancy (with women requiring the use of insulin in pregnancy less likely to participate). Binary logistic regression confirmed that insulin use negatively affected the odds of participation. The most significant barriers to participation included the accessibility, affordability and practicality of the intervention. CONCLUSIONS: Women with recent GDM face multiple barriers to lifestyle change. Intervention designers should consider: (i) the practicalities of participation for this population, (ii) research designs that capitalise on motivational differences between participants, (iii) alleviating concerns about long-term diabetes management. We hope this work will support future researchers in developing interventions that are more relevant, effective and successful in recruiting the desired population.

Vascular risk factors, cardiovascular disease and functional impairment in community-dwelling adults.

BACKGROUND: Older adults report preservation of functional independence as one of the most important constructs of successful ageing. Vascular risk factors may increase the risk of functional impairment due to clinical and subclinical vascular disease. OBJECTIVE: To describe the association between vascular risk factors and impaired ability to perform daily living activities, independent of established cardiovascular disease. METHODS: We conducted an analysis of the Clarity Cohort, which is a cross-sectional study of 9,816 community-dwelling Irish adults. Of the total cohort, 3,499 completed standardized self-reported health questionnaires, which included questions on activities of daily living. Functional impairment was defined as self-reported impairment in self-care, mobility or household tasks. Using logistic regression analyses, we determined the association between vascular risk factors and functional impairment, independent of demographics, prior coronary artery disease, stroke, congestive heart failure, and peripheral vascular disease. RESULTS: Functional impairment was reported in 40.4% (n = 1,413) of the cohort overall and in 23% of those with established cardiovascular disease. The mean age was 66.2 ± 10.3 years, 52% of the cohort were aged over 65 and 45.6% were male. Some difficulty with instrumental activities of daily living was reported by 35.4% (n = 1,240) while 29.4% (n = 1,029) reported some difficulty with basic activities of daily living. On multivariable analysis, older age [OR 1.03 (1.02, 1.04) per year], current smoking [OR 1.43 (1.08, 1.89)], atrial fibrillation [OR 1.68 (1.07, 2.65)], former alcohol use [OR 1.87 (1.36, 2.57)] and prior stroke [OR 1.91 (1.24, 2.93)] were associated with an increased risk of functional impairment. Older age leaving education [OR 0.96 (0.94, 0.99)], non-use of alcohol [OR 0.76 (0.61, 0.93)] and increased high-density lipoprotein levels [OR 0.70 (0.56, 0.88)] were associated with reduced risk of functional impairment. CONCLUSIONS: Independent of established cardiovascular disease, some vascular risk factors are associated with functional impairment. Modification of these risk factors is expected to have a large impact on preservation of functional independence through prevention of overt and covert vascular disease.

Multimorbidity's research challenges and priorities from a clinical perspective: the case of 'Mr Curran'.

Older patients, suffering from numerous diseases and taking multiple medications are the rule rather than the exception in primary care. A manifold of medical conditions are often associated with poor outcomes, and their multiple medications raise additional risks of polypharmacy. Such patients account for most healthcare expenditures. Effective approaches are needed to manage such complex patients in primary care. This paper describes the results of a scoping exercise, including a two-day workshop with 17 professionals from six countries, experienced in general practice and primary care research as well as epidemiology, clinical pharmacology, gerontology and methodology. This was followed by a consensus process investigating the challenges and core questions for multimorbidity research in primary care from a clinical perspective and presents examples of the best research practice. Current approaches in measuring and clustering multimorbidity inform policy-makers and researchers, but research is needed to provide support in clinical decision making. Multimorbidity presents a complexity of conditions leading to individual patient's needs and demanding complex processes in clinical decision making. The identification of patterns presupposes the development of strategies on how to manage multimorbidity and polypharmacy. Interventions have to be complex and multifaceted, and their evaluation poses numerous methodological challenges in study design, outcome measurement and analysis. Overall, it can be seen that complexity is a main underlying theme. Moreover, flexible study designs, outcome parameters and evaluation strategies are needed to account for this complexity.

A survey of the management of urinary tract infection in children in primary care and comparison with the NICE guidelines.

BACKGROUND: The aim of this study was to establish current practices amongst general practitioners in the West of Ireland with regard to the investigation, diagnosis and management of urinary tract infection (UTI) in children and to evaluate these practices against recently published guidelines from the National Institute for Health and Clinical Excellence (NICE). METHODS: A postal survey was performed using a questionnaire that included short clinical scenarios. All general practices in a single health region were sent a questionnaire, cover letter and SAE. Systematic postal and telephone contact was made with non-responders. The data was analysed using SPSS version 15. RESULTS: Sixty-nine general practitioners were included in the study and 50 (72%) responded to the questionnaire. All respondents agreed that it is important to consider diagnosis of UTI in all children with unexplained fever. Doctors accurately identified relevant risk factors for UTI in the majority (87%) of cases. In collecting urine samples from a one year old child, 80% of respondents recommended the use of a urine collection bag and the remaining 20% recommended collection of a clean catch sample. Respondents differed greatly in their practice with regard to detailed investigation and specialist referral after a first episode of UTI. Co-amoxiclav was the most frequently used antibiotic for the treatment of cystitis, with most doctors prescribing a five day course. CONCLUSIONS: In general, this study reveals a high level of clinical knowledge amongst doctors treating children with UTI in primary care in the catchment area of County Mayo. However, it also demonstrates wide variation in practice with regard to detailed investigation and specialist referral. The common practice of prescribing long courses of antibiotics when treating lower urinary tract infection is at variance with NICE's recommendation of a three day course of antibiotics for cystitis in children over three months of age when there are no atypical features.

Helping each other to learn--a process evaluation of peer assisted learning.

BACKGROUND: The benefits of Peer Assisted Learning (PAL) are well established with positive effects on examination scores, student satisfaction and personal and professional development reported. PAL is increasingly utilised as a resource within medical education where the restrictions on resources have forced teachers to look at creating new educational environments which can be delivered at a lower cost. This study sought to evaluate the processes at work as the emphasis of PAL research to date has largely been on the consideration of student outcomes. METHODS: Fifth-year medical undergraduates, who had completed their communication skills modular training and attended a preparatory workshop, facilitated a role-play session for their second-year colleagues within an Early Patient Contact programme. Semi-structured interviews and focus groups were used to collect data at different time points in order to establish the views of peer learners and tutors towards this new method of teaching. The data was analysed according to the principles framework analysis using N-vivo software. Themes were shared and debated with the multidisciplinary team of authors and a concordance of views on common themes was reached after discussion and debate. RESULTS: Analysis of the data resulted in the emergence of three thematic categories: Learning Environment, Educational Exchange and Communication and Modelling. The data demonstrated a concordance of the views between peer tutors and learners on barriers and levers of this approach as well as a heightened awareness of the learning environment and the educational exchange occurring therein. CONCLUSION: The data is significant as it not only demonstrates a high level of acceptability among tutors and learners for PAL but also indicates the reciprocity of educational exchange that appears to occur within the PAL setting. This study highlights some of the unique characteristics of PAL and we recommend the development of further qualitative studies around peer learners and tutors views of this process.
