Abstract
Objective: The objective of this study was to determine whether trajectories of older adults' alcohol consumption are influenced by the following life course transitions, relationship status, employment status, and self-rated health. Method: Volume and frequency of drinking were harmonized across first three waves of The Irish Longitudinal Study on Ageing (TILDA; N = 4,295). Multilevel regression models were used to model frequency, average weekly consumption, and heavy episodic drinking. Results: Men and women drank more frequently over time, with frequency decreasing with age for women. Average weekly consumption decreased over time and with increasing age. Transitions in self-rated health, particularly those reflecting poorer health, were associated with lower frequency and weekly consumption. Heavy episodic drinking decreased with age. Men who were retired across all waves were more likely to engage in heavy episodic drinking at baseline. Discussion: Despite the decline in average weekly consumption and heavy episodic drinking, the observed quantities consumed and the increase in frequency of consumption suggest that older Irish adults remain vulnerable to alcohol-related harms.

Abstract
INTRODUCTION Community pharmacy is an ideal setting to monitor medication adherence, however, barriers to pharmacist-led interventions exist. Preparing future pharmacists for enhanced roles may overcome such barriers. Our objective was to identify medication monitoring attitudes and contextual factors that influence adherence monitoring by pharmacy interns to inform educational activities on medication adherence. METHODS An online factorial survey of all pharmacy interns (N = 123) in the Republic of Ireland, completing advanced community pharmacy experiential learning in May 2016 was undertaken to evaluate attitudes to medication monitoring and to identify respondent characteristics and contextual factors which influence adherence monitoring of older hypertensive adults during repeat dispensing. The medication monitoring attitude measure (MMAM) was used to evaluate interns' attitudes, and factorial vignette analysis was performed to identify factors influencing behavioural intention to offer adherence advice. RESULTS There were 121 completed online surveys. Half of interns reported they felt uncomfortable and confrontational discussing adherence with patients. In factorial vignette analysis, higher medication monitoring attitudes resulted in higher likelihood to offer adherence advice; experiential-learning characteristics such as pharmacy ownership-type (nonchain store) and contextual factors including patients being treated for longer and time-pressures had a significant negative influence on pharmacy interns' likelihood to offer adherence advice. DISCUSSION Medication monitoring attitudes and contextual factors influenced responses to offer adherence advice in hypothetical scenarios. Ensuring pharmacy students are educated on patterns of adherence and appropriate skills to address nonadherence, and engage in structured programmes to facilitate patient interactions during experiential learning, may improve medication monitoring attitudes and adherence monitoring.

Abstract
OBJECTIVES Older adults are particularly vulnerable to adverse effects from concurrent alcohol and medication use. However, there is limited evidence regarding the prevalence of these adverse outcomes among older adults, and there is a lack of consensus regarding what constitutes an alcohol-interactive medicine. The objective of this study was to develop an explicit list of potentially serious alcohol-medication interactions for use in older adults. DESIGN Following a systematic review, review of drug compendia and clinical guidance documents, a two-round Delphi consensus method was conducted. SETTING Ireland and the United Kingdom (UK), primary care and hospital setting. PARTICIPANTS The Project Steering Group developed a list of potentially serious alcohol-medication interactions. The Delphi panel consisted of 19 healthcare professionals (general practitioners, geriatricians, hospital and community pharmacists, clinical pharmacologists and pharmacists, and physicians specialising in substance misuse). RESULTS An inventory of 52 potentially serious alcohol-medication interactions was developed by the Project Steering Group. British National Formulary black dot warnings (n=8) were included in the final criteria as they represent 'potentially serious' interactions. The remaining 44 criteria underwent a two-round Delphi process. In the first round, 13 criteria were accepted into the POtentially Serious Alcohol-Medication INteractions in Older adults (POSAMINO) criteria. Consensus was not reached on the remaining 31 criteria; 9 were removed and 8 additional criteria were included following a review of panellist comments. The remaining 30 criteria went to round 2, with 17 criteria reaching consensus, providing a final list of 38 potentially serious alcohol-medication interactions: central nervous system (n=15), cardiovascular system (n=9), endocrine system (n=5), musculoskeletal system (n=3), infections (n=3), malignant disease and immunosuppression (n=2), and respiratory system (n=1). CONCLUSIONS POSAMINO is the first set of explicit potentially serious alcohol-medication interactions for use in older adults. Following future validation studies, these criteria may allow for the risk stratification of older adults at the point of prescribing.

Abstract
Antihypertensive medication nonadherence is highly prevalent, leading to uncontrolled blood pressure. Methods that facilitate the targeting and tailoring of adherence interventions in clinical settings are required. Group‐Based Trajectory Modeling (GBTM) is a newer method to evaluate adherence using pharmacy dispensing (refill) data that has advantages over traditional refill adherence metrics (e.g. Proportion of Days Covered) by identifying groups of patients who may benefit from adherence interventions, and identifying patterns of adherence behavior over time that may facilitate tailoring of an adherence intervention. We evaluated adherence to antihypertensive medication in 905 patients over a 12‐month period in a community pharmacy setting using GBTM, identifying three subgroups of adherence patterns: 52.8%, 40.7%, and 6.5% had very high, high, and low adherence, respectively. However, GBTM failed to demonstrate predictive validity with blood pressure at 12 months. Further research on the validity of adherence measures that facilitate interventions in clinical settings is required.

Abstract
BACKGROUND Older adults are susceptible to adverse effects from the concurrent use of medications and alcohol. The aim of this study was to systematically review the prevalence of concurrent use of alcohol and alcohol-interactive (AI) medicines in older adults and associated adverse outcomes. METHODS A systematic search was performed using MEDLINE (PubMed), Embase, Scopus and Web of Science (January 1990 to June 2016), and hand searching references of retrieved articles. Observational studies reporting on the concurrent use of alcohol and AI medicines in the same or overlapping recall periods in older adults were included. Two independent reviewers verified that studies met the inclusion criteria, critically appraised included studies and extracted relevant data. A narrative synthesis is provided. RESULTS Twenty studies, all cross-sectional, were included. Nine studies classified a wide range of medicines as AI using different medication compendia, thus resulting in heterogeneity across studies. Three studies investigated any medication use and eight focused on psychotropic medications. Based on the quality assessment of included studies, the most reliable estimate of concurrent use in older adults ranges between 21 and 35%. The most reliable estimate of concurrent use of psychotropic medications and alcohol ranges between 7.4 and 7.75%. No study examined longitudinal associations with adverse outcomes. Three cross-sectional studies reported on falls with mixed findings, while one study reported on the association between moderate alcohol consumption and adverse drug reactions at hospital admission. CONCLUSIONS While there appears to be a high propensity for alcohol-medication interactions in older adults, there is a lack of consensus regarding what constitutes an AI medication. An explicit list of AI medications needs to be derived and validated prospectively to quantify the magnitude of risk posed by the concurrent use of alcohol for adverse outcomes in older adults. This will allow for risk stratification of older adults at the point of prescribing, and prioritise alcohol screening and brief alcohol interventions in high-risk groups.

Abstract
INTRODUCTION Mechanically ventilated children in paediatric intensive care units are commonly administered analgesics and sedative agents to minimise pain and distress and facilitate cooperation with medical interventions. Opioids and benzodiazepines are the most common analgesic and sedative agents but have safety concerns. The α2 agonists clonidine and dexmedetomidine are alternative sedatives in use despite neither having robust evidence to support their use. Studies evaluating effectiveness of α2 agonists to date have not focused on sedation-based outcomes instead focusing on opioid-sparing properties and ventilation outcomes. The aim of this study is to evaluate if an opioid-based sedation regimen, with an α2 agonist adjunct (clonidine or dexmedetomidine), produces a non-inferior proportion of time adequately sedated compared with a control group without an α2 agonist adjunct, while conferring potential additional benefits such as reduced opioid administration and less exposure to potential additional agents such as benzodiazepines. METHODS AND ANALYSIS We will conduct a retrospective cohort study in two Irish paediatric intensive care units using clinical information on patient characteristics, sedation scores and drug use. Eligible children admitted between January 2014 and June 2016 who were mechanically ventilated and received an opioid infusion will be included. Patients will be categorised into two exposure categories (received an α2 agonist or did not receive an α2 agonist) and the time adequately sedated (measured using the COMFORT Behaviour Score) will be calculated using interpolation of nursing sedation scores at each recorded time point. At least 150 per group is planned for inclusion to ensure adequate study power. Propensity score matching will be used in analysis to account for potential confounding by indication. ETHICS AND DISSEMINATION The study has been approved by the ethics committees of both hospitals. Dissemination will occur via local, national and international presentations for academic and healthcare audiences as well as through peer reviewed publications.

Abstract
Background older adults are frequent users of emergency services and demonstrate high rates of adverse outcomes following emergency care. Objective to perform a systematic review and meta-analysis of the Identification of Seniors At Risk (ISAR) screening tool, to determine its predictive value in identifying adults ≥65 years at risk of functional decline, unplanned emergency department (ED) readmission, emergency hospitalisation or death within 180 days after index ED visit/hospitalisation. Methods a systematic literature search was conducted in PubMed, EMBASE, CINAHL, EBSCO and the Cochrane Library to identify validation and impact analysis studies of the ISAR tool. A pre-specified ISAR score of ≥2 (maximum score 6 points) was used to identify patients at high risk of adverse outcomes. A bivariate random effects model generated pooled estimates of sensitivity and specificity. Statistical heterogeneity was explored and methodological quality was assessed using validated criteria. Results thirty-two validation studies (n = 12,939) are included. At ≥2, the pooled sensitivity of the ISAR for predicting ED return, emergency hospitalisation and mortality at 6 months is 0.80 (95% confidence interval (CI) 0.70-0.87), 0.82 (95% CI 0.74-0.88) and 0.87 (95% CI 0.75-0.94), respectively, with a pooled specificity of 0.31 (95% CI 0.24-0.38), 0.32 (95% CI 0.24-0.41) and 0.35 (95% CI 0.26-0.44). Similar values are demonstrated at 30 and 90 days. Three heterogeneous impact analysis studies examined the clinical implementation of the ISAR and reported mixed findings across patient and process outcomes. Conclusion the ISAR has modest predictive accuracy and may serve as a decision-making adjunct when determining which older adults can be safely discharged.

Abstract
BACKGROUND Shared care has been used in the management of many chronic conditions with the assumption that it delivers better care than primary or specialty care alone; however, little is known about the effectiveness of shared care. OBJECTIVES To determine the effectiveness of shared care health service interventions designed to improve the management of chronic disease across the primary/specialty care interface. This is an update of a previously published review.Secondary questions include the following:1. Which shared care interventions or portions of shared care interventions are most effective?2. What do the most effective systems have in common? SEARCH METHODS We searched MEDLINE, Embase and the Cochrane Library to 12 October 2015. SELECTION CRITERIA One review author performed the initial abstract screen; then two review authors independently screened and selected studies for inclusion. We considered randomised controlled trials (RCTs), non-randomised controlled trials (NRCTs), controlled before-after studies (CBAs) and interrupted time series analyses (ITS) evaluating the effectiveness of shared care interventions for people with chronic conditions in primary care and community settings. The intervention was compared with usual care in that setting. DATA COLLECTION AND ANALYSIS Two review authors independently extracted data from the included studies, evaluated study quality and judged the certainty of the evidence using the GRADE approach. We conducted a meta-analysis of results when possible and carried out a narrative synthesis of the remainder of the results. We presented the results in a 'Summary of findings' table, using a tabular format to show effect sizes for all outcome types. MAIN RESULTS We identified 42 studies of shared care interventions for chronic disease management (N = 18,859), 39 of which were RCTs, two CBAs and one an NRCT. Of these 42 studies, 41 examined complex multi-faceted interventions and lasted from six to 24 months. Overall, our confidence in results regarding the effectiveness of interventions ranged from moderate to high certainty. Results showed probably few or no differences in clinical outcomes overall with a tendency towards improved blood pressure management in the small number of studies on shared care for hypertension, chronic kidney disease and stroke (mean difference (MD) 3.47, 95% confidence interval (CI) 1.68 to 5.25)(based on moderate-certainty evidence). Mental health outcomes improved, particularly in response to depression treatment (risk ratio (RR) 1.40, 95% confidence interval (CI) 1.22 to 1.62; six studies, N = 1708) and recovery from depression (RR 2.59, 95% CI 1.57 to 4.26; 10 studies, N = 4482) in studies examining the 'stepped care' design of shared care interventions (based on high-certainty evidence). Investigators noted modest effects on mean depression scores (standardised mean difference (SMD) -0.29, 95% CI -0.37 to -0.20; six studies, N = 3250). Differences in patient-reported outcome measures (PROMs), processes of care and participation and default rates in shared care services were probably limited (based on moderate-certainty evidence). Studies probably showed little or no difference in hospital admissions, service utilisation and patient health behaviours (with evidence of moderate certainty). AUTHORS' CONCLUSIONS This review suggests that shared care improves depression outcomes and probably has mixed or limited effects on other outcomes. Methodological shortcomings, particularly inadequate length of follow-up, may account in part for these limited effects. Review findings support the growing evidence base for shared care in the management of depression, particularly stepped care models of shared care. Shared care interventions for other conditions should be developed within research settings, with account taken of the complexity of such interventions and awareness of the need to carry out longer studies to test effectiveness and sustainability over time.

Abstract
OBJECTIVES Clinical practice guidelines (CPGs) support the translation of research evidence into clinical practice. Key health questions in CPGs ensure that recommendations will be applicable to the clinical context in which the guideline is used. The objectives of this study were to identify CPGs for the pharmacological treatment of first-episode schizophrenia; assess the quality of these guidelines using the Appraisal of Guidelines for Research and Evaluation II (AGREE II) instrument; and compare recommendations in relation to the key health questions that are relevant to the pharmacological treatment of first-episode schizophrenia. METHODS A multidisciplinary group identified key health questions that are relevant to the pharmacological treatment of first-episode schizophrenia. The MEDLINE and EMBASE databases, websites of professional organisations and international guideline repositories, were searched for CPGs that met the inclusion criteria. The AGREE II instrument was applied by three raters and data were extracted from the guidelines in relation to the key health questions. RESULTS In total, 3299 records were screened. 10 guidelines met the inclusion criteria. 3 guidelines scored well across all domains. Recommendations varied in specificity. Side effect concerns, rather than comparative efficacy benefits, were a key consideration in antipsychotic choice. Antipsychotic medication is recommended for maintenance of remission following a first episode of schizophrenia but there is a paucity of evidence to guide duration of treatment. Clozapine is universally regarded as the medication of choice for treatment resistance. There is less evidence to guide care for those who do not respond to clozapine. CONCLUSIONS An individual's experience of using antipsychotic medication for the initial treatment of first-episode schizophrenia may have implications for future engagement, adherence and outcome. While guidelines of good quality exist to assist in medicines optimisation, the evidence base required to answer key health questions relevant to the pharmacological treatment of first-episode schizophrenia is limited.

Abstract
AIM One of the main provisions of the Irish Public Health (Alcohol) Bill is the introduction of a minimum unit price (MUP) for alcohol in Ireland, set at €1.00/standard drink. We sought to identify who will be most affected by the introduction of a MUP, examining the relationship between harmful alcohol consumption, personal income, place of purchase and price paid for alcohol. METHOD A nationally representative survey of 3187 respondents aged 18-75 years, completing a diary of their previous week's alcohol consumption. The primary outcome was purchasing alcohol at <€1.00/standard drink; secondary outcome was purchasing alcohol at <€1.00/standard drink off-sales. Primary exposures were harmful alcohol consumption (AUDIT-C > 5), low personal annual income (<€20,000) and place of purchase (off- or- on-sales). RESULTS One in seven respondents (14%) spent <€1.00/standard drink, with a median spend of 0.78/standard drink. High-risk drinkers (OR 1.56, 95% CI 1.09-2.23), men (OR 1.95, 95% CI 1.43-2.66), people on low income (OR 1.64, 95% CI 1.20-2.23) and those purchasing alcohol off-sales (OR 21.9, 95% CI 12.5-38.1) were most likely to report purchasing alcohol at <€1.00/standard drink. Forty-four per cent of alcohol consumed was purchased off-sales. Of those purchasing off-sales, 30% bought cheap alcohol. High-risk drinkers, men and those on low income were most likely to report paying < €1.00/standard drink off-sales. CONCLUSION Heavy drinkers, men and those on low income seek out the cheapest alcohol. The introduction of a MUP in Ireland is likely to target those suffering the greatest harm, and reduce alcohol-attributable mortality in Ireland. Further prospective studies are needed to monitor consumption trends and associated harms following the introduction of minimum unit pricing of alcohol.

Estimating Risk of Alcohol Dependence Using Empirically Validated Ordinal Risk Zones Versus Recommended Binary Risk Zones of the RAPS4: A Validation Study Using Stratum-Specific Likelihood Ratio Analysis.

Abstract
BACKGROUND Effective treatment options for alcohol dependence exist; yet, only 10% of people with alcohol dependence receive treatment. The objective of the current study was to examine the performance of previously recommended Rapid Alcohol Problem Screen 4 (RAPS4) risk zones, based on single binary cut-points (RAPS4 ≥ 1; RAPS4 ≥ 2), and empirically identified RAPS4 risk zones to identify people with alcohol dependence so that further diagnostic assessment or interventions can be offered. METHOD Stratum-specific likelihood ratio (SSLR) and receiver operating characteristic analyses were used to compare the screening performance of empirically identified "risk zones" on the RAPS4 to previously recommended binary cut-points in a general population sample of current drinkers in Ireland (N = 4,267). SSLRs were also used along with the pretest prevalence of alcohol dependence to estimate posttest probabilities of alcohol dependence for the recommended and empirically identified risk zones. RESULTS The weighted prevalence estimate of alcohol dependence among current drinkers was 6.9% (9.3% men; 4.5% women). The SSLR analysis identified multiple risk zones in the RAPS4, with each of the individual scores (0, 1, 2, 3, 4) retained as 5 separate ordinal risk zones for both men and women. A comparison of the area under the receiver operating characteristic curve showed that the ordinal RAPS4 risk zones performed better than recommended binary thresholds for both men and women. Based on the pretest probability of 9.3% and the identified SSLRs for the ordinal risk zones, the posttest probability of alcohol dependence for men ranged from 1.6% for those in the lower risk zone (RAPS4 = 0) to 86.7% for those in the highest risk zone (RAPS4 = 4). The posttest probability of alcohol dependence for women ranged from 0.4% for those in the lower risk zone to 80% for those in the higher risk zone. CONCLUSIONS The detection of alcohol dependence may be improved using the empirically identified ordinal RAPS4 risk zones for both men and women. The application of the identified SSLRs, particularly if integrated into a clinical decision support system, may be helpful for clinicians in providing feedback to patients regarding their risk of alcohol dependence.

Abstract
Chronic non-malignant pain (CNMP) is commonly managed by General Practitioners (GPs) in primary care. Analgesics are the mainstay of CNMP management in this setting. Selection of medications by GPs may be influenced by micro factors which are relevant to the practice setting, meso factors which relate to the local or regional environment or macro factors such as those arising from national or international influences. The aim of this study is to explore influences on GP practises in relation to pain management for older adults with CNMP. Semi-structured interviews were conducted with 12 GPs. Transcripts were organised using the Framework Method of Data Management while an applied thematic analysis was used to identify the themes emerging from the data. Clinical considerations such as the efficacy of analgesics, adverse effects and co-morbidities strongly influence prescribing decisions. The GPs interviewed identified the lack of guidance on this subject in Ireland and described the impact of organisational and structural barriers of the Irish healthcare system on the management of CNMP. Changes in practice behaviours coupled with health system reforms are required to improve the quality and consistency of pharmacotherapeutic management of CNMP in primary care.

Abstract
AIM To assess whether risk of death increases during periods of treatment transition, and investigate the impact of supervised methadone consumption on drug-related and all-cause mortality. DESIGN National Irish cohort study. SETTING Primary care. PARTICIPANTS A total of 6983 patients on a national methadone treatment register aged 16-65 years between 2004 and 2010. MEASUREMENT Drug-related (primary outcome) and all-cause (secondary outcome) mortality rates and rate ratios for periods on and off treatment; and the impact of regular supervised methadone consumption. RESULTS Crude drug-related mortality rates were 0.24 per 100 person-years on treatment and 0.39 off treatment, adjusted mortality rate ratio 1.63 [95% confidence interval (CI) = 0.66-4.00]. Crude all-cause mortality rate per 100 person-years was 0.51 on treatment versus 1.57 off treatment, adjusted mortality rate ratio 3.64 (95% CI = 2.11-6.30). All-cause mortality off treatment was 6.36 (95% CI = 2.84-14.22) times higher in the first 2 weeks, 9.12 (95% CI = 3.17-26.28) times higher in weeks 3-4, compared with being 5 weeks or more in treatment. All-cause mortality was lower in those with regular supervision (crude mortality rate 0.60 versus 0.81 per 100 person-years) although, after adjustment, insufficient evidence exists to suggest that regular supervision is protective (mortality rate ratio = 1.23, 95% CI = 0.67-2.27). CONCLUSIONS Among primary care patients undergoing methadone treatment, continuing in methadone treatment is associated with a reduced risk of death. Patients' risk of all-cause mortality increases following treatment cessation, and is highest in the initial 4-week period.

Abstract
Forty-four patients who had image-guided corticosteroid injection of the hip were reviewed as part of a service improvement project to ascertain the medium term benefit of the procedure. Injections were indicated for treatment of hip pain or as part of a diagnostic work up to differentiate hip from back pain. At 42-month review, 39 patients fulfilled the criteria for the study. Of those having therapeutic injections, 70% had gone on to hip replacement, while only 20% of those having diagnostic injections had done so. These results suggest that, for patients who are fit for surgery, hip replacement should be the intervention of choice as corticosteroid injection does not substantially delay the need for surgery. Where there is doubt about the source of pain, there seems to be a clear role for diagnostic injection.

Potential for alcohol and drug interactions in older adults: evidence from the Irish longitudinal study on ageing. BMC Geriatr 2014; 14:57.

Abstract
BACKGROUND Older adults are susceptible to adverse effects from the concomitant use of prescription medications and alcohol. This study estimates the prevalence of exposure to alcohol interactive (AI) medications and concomitant alcohol use by therapeutic class in a large, nationally representative sample of older adults. METHODS Cross-sectional analysis of a population based sample of older Irish adults aged ≥60 years using data from The Irish Longitudinal Study on Ageing (TILDA) (N = 3,815). AI medications were identified using Stockley's Drug Interactions, the British National Formulary and the Irish Medicines Formulary. An in-home inventory of medications was used to characterise AI drug exposure by therapeutic class. Self-reported alcohol use was classified as non-drinker, light/moderate and heavy drinking. Comorbidities known to be exacerbated by alcohol were also recorded (diabetes mellitus, hypertension, peptic ulcer disease, liver disease, depression, gout or breast cancer), as well as sociodemographic and health factors. RESULTS Seventy-two per cent of participants were exposed to AI medications, with greatest exposure to cardiovascular and CNS agents. Overall, 60% of participants exposed to AI medications reported concomitant alcohol use, compared with 69.5% of non-AI exposed people (p < 0.001). Almost 28% of those reporting anti-histamine use were identified as heavy drinkers. Similarly almost one in five, combined heavy drinking with anti-coagulants/anti-platelets and cardiovascular agents, with 16% combining heavy drinking with CNS agents. Multinomial logistic regression showed that being male, younger, urban dwelling, with higher levels of education and a history of smoking, were associated with an increased risk for concomitant exposure to alcohol consumption (both light/moderate and heavier) and AI medications. Current smokers and people with increasing co-morbidities were also at greatest risk for heavy drinking in combination with AI medications. CONCLUSIONS The concurrent use of alcohol with AI medications, or with conditions known to be exacerbated by alcohol, is common among older Irish adults. Prescribers should be aware of potential interactions, and screen patients for alcohol use and provide warnings to minimize patient risk.

Abstract
BACKGROUND Several studies have examined condom use during 'holiday' sex but have not considered condom errors in this context. This study aims to identify factors associated with late application of condoms during participants' most recent vaginal intercourse at home and away from home (holidays or short breaks). METHOD Participants aged 19-30 years from a national Irish survey were recontacted (n=388; 51% men; mean age: 23.9 years). Telephone interviews regarding participants' most recent sex at home (n=362) and away from home (n=178) were conducted. RESULTS A higher proportion reported condom use away from home (79% v. 62%), with a lower prevalence of late application (14% v. 24%). Pregnancy prevention as the primary motive for condom use increased the odds of late application at home (adjusted odds ratio (AOR): 4.56, 95% confidence interval (CI): 2.10-9.90) and away (AOR: 3.97, 95% CI: 1.36-11.59). A weak desire to use a condom also increased the likelihood of late application at home (AOR: 2.40, 95% CI: 1.03-5.62) and away (AOR: 11.18, 95% CI: 2.84-43.98). Subgroup analysis of those reporting both sexual events suggests that young adults take greater sexual risks with casual partners at home compared to away. CONCLUSIONS The findings suggest that young adults take greater sexual risks at home than when away. Regardless of location, young adults are most likely to report late application when they have a weak desire to use a condom and when they use condoms primarily to prevent pregnancy.

Abstract
This retrospective study evaluated 69 Swanson trapezium replacements performed between 1990 and 2009 for trapeziometacarpal osteoarthritis in 58 patients. Pain and function were assessed using the Michigan Hand Questionnaire and the Disability of the Arm, Shoulder and Hand questionnaire. Patients had a mean age of 62 years at the time of surgery, with a mean time of 7.7 years (range 9 months to 19 years) from surgery to follow-up interview. There was no association between outcome scores and the length of follow-up, suggesting that the results are maintained over time (Spearman's rank correlation test < ±0.2). Scores for activities of daily living and work-related activities were higher when surgery was on the dominant hand (p < 0.05). Silicone trapezium replacement remains a good option for patients with painful trapeziometacarpal osteoarthritis that has not responded to nonoperative management.

Abstract
This study aims to identify periods of elevated risk of drug-related mortality during methadone maintenance treatment (MMT) in primary care using a cohort of 3,162 Scottish drug users between January 1993 and February 2004. Deaths occurring during treatment or within 3 days after last methadone prescription expired were considered as cases "on treatment." Fatalities occurring 4 days or more after leaving treatment were cases "off treatment." Sixty-four drug-related deaths were identified. The greatest risk of drug-related death was in the first 2 weeks of treatment (adjusted hazard ratio 2.60, 95% confidence interval 1.03-6.56). Risk of drug-related death was lower after the first 30 days following treatment cessation, relative to the first 30 days off treatment. History of psychiatric admission was associated with increased risk of drug-related death in treatment. Increasing numbers of treatment episodes and urine testing were protective. History of psychiatric admission, increasing numbers of urine tests, and coprescriptions of benzodiazepines increased the risk of mortality out of treatment. The risk of drug-related mortality in MMT is elevated during periods of treatment transition, specifically treatment initiation and the first 30 days following treatment dropout or discharge.

Abstract
OBJECTIVE The purpose of this systematic review with meta-analysis is to determine the diagnostic accuracy of the identification of migraine (ID Migraine) as a decision rule for identifying patients with migraine. BACKGROUND The ID Migraine screening tool is designed to identify patients with migraine in primary care settings. Several studies have validated the ID Migraine across various clinical settings, including primary care, neurology departments, headache clinics, dental clinics, ear, nose, and throat (ENT) and ophthalmology. METHODS A systematic literature search was conducted to identify all studies validating the ID Migraine, with the International Headache Criteria as the reference standard. The methodological quality of selected studies was assessed using the Quality of Diagnostic Accuracy Studies tool. All selected studies were combined using a bivariate random effects model. A sensitivity analysis was also conducted, pooling only those studies using representative patient groups (primary care, neurology departments, and headache clinics) to determine the potential influence of spectrum bias on the results. RESULTS Thirteen studies incorporating 5866 patients are included. The weighted prior probability of migraine across the 13 studies is 59%. The ID Migraine is shown to be useful for ruling out rather than ruling in migraine, with a greater pooled sensitivity estimate (0.84, 95% confidence interval 0.75-0.90) than specificity (0.76, 95% confidence interval 0.69-0.83). A negative ID Migraine score reduces the probability of migraine from 59% to 23%. The sensitivity analysis reveals similar results. CONCLUSIONS This systematic review quantifies the diagnostic accuracy of the ID Migraine as a brief, practical, and easy to use diagnostic tool for Migraine. Application of the ID Migraine as a diagnostic tool is likely to improve appropriate diagnosis and management of migraine sufferers.

Abstract
BACKGROUND In this paper, we give an overview of methadone treatment in Ireland and outline the rationale for designing an electronic health record (EHR) with extensibility, interoperability and decision support functionality. Incorporating several international standards, a conceptual model applying a problem orientated approach in a hierarchical structure has been proposed for building the EHR. METHODS A set of archetypes has been designed in line with the current best practice and clinical guidelines which guide the information-gathering process. A web-based data entry system has been implemented, incorporating elements of the paper-based prescription form, while at the same time facilitating the decision support function. RESULTS The use of archetypes was found to capture the ever changing requirements in the healthcare domain and externalises them in constrained data structures. The solution is extensible enabling the EHR to cover medicine management in general as per the programme of the HRB Centre for Primary Care Research. CONCLUSIONS The data collected via this Irish system can be aggregated into a larger dataset, if necessary, for analysis and evidence-gathering, since we adopted the openEHR standard. It will be later extended to include the functionalities of prescribing drugs other than methadone along with the research agenda at the HRB Centre for Primary Care Research in Ireland.

Abstract
Background Acute urinary tract infections (UTI) are one of the most common bacterial infections among women presenting to primary care. However, there is a lack of consensus regarding the optimal reference standard threshold for diagnosing UTI. The objective of this systematic review is to determine the diagnostic accuracy of symptoms and signs in women presenting with suspected UTI, across three different reference standards (102 or 103 or 105 CFU/ml). We also examine the diagnostic value of individual symptoms and signs combined with dipstick test results in terms of clinical decision making. Methods Searches were performed through PubMed (1966 to April 2010), EMBASE (1973 to April 2010), Cochrane library (1973 to April 2010), Google scholar and reference checking. Studies that assessed the diagnostic accuracy of symptoms and signs of an uncomplicated UTI using a urine culture from a clean-catch or catherised urine specimen as the reference standard, with a reference standard of at least ≥ 102 CFU/ml were included. Synthesised data from a high quality systematic review were used regarding dipstick results. Studies were combined using a bivariate random effects model. Results Sixteen studies incorporating 3,711 patients are included. The weighted prior probability of UTI varies across diagnostic threshold, 65.1% at ≥ 102 CFU/ml; 55.4% at ≥ 103 CFU/ml and 44.8% at ≥ 102 CFU/ml ≥ 105 CFU/ml. Six symptoms are identified as useful diagnostic symptoms when a threshold of ≥ 102 CFU/ml is the reference standard. Presence of dysuria (+LR 1.30 95% CI 1.20-1.41), frequency (+LR 1.10 95% CI 1.04-1.16), hematuria (+LR 1.72 95%CI 1.30-2.27), nocturia (+LR 1.30 95% CI 1.08-1.56) and urgency (+LR 1.22 95% CI 1.11-1.34) all increase the probability of UTI. The presence of vaginal discharge (+LR 0.65 95% CI 0.51-0.83) decreases the probability of UTI. Presence of hematuria has the highest diagnostic utility, raising the post-test probability of UTI to 75.8% at ≥ 102 CFU/ml and 67.4% at ≥ 103 CFU/ml. Probability of UTI increases to 93.3% and 90.1% at ≥ 102 CFU/ml and ≥ 103 CFU/ml respectively when presence of hematuria is combined with a positive dipstick result for nitrites. Subgroup analysis shows improved diagnostic accuracy using lower reference standards ≥ 102 CFU/ml and ≥ 103 CFU/ml. Conclusions Individual symptoms and signs have a modest ability to raise the pretest-risk of UTI. Diagnostic accuracy improves considerably when combined with dipstick tests particularly tests for nitrites.
