Selected AbstractsThe relative efficacy of two levels of a primary care intervention for family members affected by the addiction problem of a close relative: a randomized trialADDICTION, Issue 1 2009Alex Copello ABSTRACT Objectives A randomized trial to compare two levels of an intervention (full versus brief) for use by primary health-care professionals with family members affected by the problematic drug or alcohol use of a close relative. Design A prospective cluster randomized comparative trial of the two interventions. Setting A total of 136 primary care practices in two study areas within the West Midlands and the South West regions of England. Participants A total of 143 family members affected by the alcohol or drug problem of a relative were recruited into the study by primary health-care professionals. All recruited family members were seen on at least one occasion by the professional delivering the intervention and 129 (90 %) were followed-up at 12 weeks. Main outcome measures Two validated and standardized self-completion questionnaires measuring physical and psychological symptoms of stress (Symptom Rating Test) and behavioural coping (Coping Questionnaire) experienced by the family members. It was predicted that the full intervention would show increased reduction in both symptoms and coping when compared to the brief intervention. Results The primary analysis adjusted for clustering, baseline symptoms and stratifying variables (location and professional group) showed that there were no significant differences between the two trial arms. The symptom score at follow-up was 0.23 [95% confidence interval (CI): ,3.65, +4.06] higher in the full intervention arm than in the brief intervention arm, and the coping score at follow-up was 0.12 (95% CI: ,5.12, +5.36) higher in the full intervention arm than in the brief intervention arm. Conclusions A well-constructed self-help manual delivered by a primary care professional may be as effective for family members as several face-to-face sessions with the professional. [source] Effectiveness of brief structured interventions on risk factor modification for patients with coronary heart disease: a systematic reviewINTERNATIONAL JOURNAL OF EVIDENCE BASED HEALTHCARE, Issue 4 2007Ritin Fernandez RN MN (Critical care) PhD Candidate Abstract Background, The physical and psychosocial benefits of participation in cardiac rehabilitation following a coronary event have well been established. Despite these benefits there is strong evidence that participation in traditional cardiac rehabilitation programs remains low. Various models of cardiac rehabilitation have been implemented including the use of brief structured interventions to enable modification of coronary risk factors. Objectives, The objective of this review was to determine the effect of brief structured interventions on risk factor modification in patients with coronary heart disease. Search strategy, A literature search was performed using the following databases MEDLINE (1966,2006), CINAHL (1982,2006), EMBASE (1980,current) and up to the Cochrane Controlled Trials Register (Issue 2, 2006 of Cochrane Library). In addition, the reference lists of relevant trials and conference proceedings were also scrutinised. Company representatives, experts and investigators were contacted to elicit further information. Selection criteria, All randomised and quasi-randomised controlled trials that compared the effects of brief structured interventions on risk factor modification in patients with coronary heart disease were considered for inclusion in the review. Data collection and analysis, Eligibility of the trials for inclusion in the review, details of eligible trials and the methodological quality of the trials were assessed independently by two reviewers. Relative risks for dichotomous data and a weighted mean difference for continuous data were calculated with 95% confidence intervals. Where synthesis was inappropriate, trials were considered separately. Main results, Seventeen trials involving a total of 4725 participants were included in the final review: three trials compared the effects of brief structured interventions on diet modification; seven on smoking cessation; and seven on multiple risk factors. Two trials involving 76 patients compared brief structured intervention versus usual care for dietary modification. Although there was a tendency for more participants in the intervention arm to lose weight at the 12-week follow up and achieve target cholesterol levels at the 6-month follow up, these results were not statistically significant. Only one small trial involving 36 patients compared brief structured intervention and extensive intervention for dietary modification and demonstrated a significant reduction in the percentage of energy obtained from fat and saturated fat intake among participants receiving extensive intervention. However, no difference in fish, fruit and vegetable intake between the groups was evident. Six trials involving 2020 patients compared brief structured intervention versus usual care for smoking cessation. There was no difference in the smoking cessation rates at the 3- and 6-week follow up, however, there was evidence of a benefit of brief structured interventions for smoking cessation at the 3-, 6- and 12-month follow up. In the only trial that and compared brief structured intervention and extensive intervention for smoking cessation in 254 participants there was no clear difference of a likelihood of smoking cessation between the two groups. In the seven trials that compared brief structured intervention and usual care for multiple risk factor modification there was evidence of a benefit of the intervention on behavioural changes such as fat intake, weight loss and consequently on reduction in the body mass index, smoking cessation and physical activity among the participants. The findings concerning the effect on blood pressure, blood glucose levels and the lipid profile, however, remain inconclusive. Conclusions, There is suggestive but inconclusive evidence from the trials of a benefit in the use of brief interventions for risk factor modification in patients with coronary heart disease. This review, however, supports the concept that brief interventions for patients with coronary heart disease can have beneficial effects on risk factor modification and consequently on progression of coronary heart disease. Further trials using larger sample sizes need to be undertaken to demonstrate the benefits of brief structured intervention targeted at the modification of single or multiple risk factors. [source] Treating late-life depression with interpersonal psychotherapy in the primary care sectorINTERNATIONAL JOURNAL OF GERIATRIC PSYCHIATRY, Issue 2 2007Herbert C. Schulberg Abstract Background Interpersonal psychotherapy (IPT) is an empirically-validated intervention for treating late-life depression. Objective To determine the manner in which IPT is utilized by primary care physicians in relation to antidepressant medications. Methods The authors reviewed treatment logs prepared by care managers during the first 12 months of a patient's participation in the PROSPECT clinical trial to determine initial and longitudinal treatment patterns utilized by physicians, and clinical outcomes associated with initial treatment assignment. Results Primary care physicians in practices randomized to PROSPECT's intervention arm initially prescribed an antidepressant medication for 58% of eligible patients and referred only 11% of them to IPT. Over time, however, 27% of patients participated in IPT as monotherapy or augmentation therapy. Initial treatment assignment was not associated with depressive status at 4 and 12 months nor with suicidal ideation at 4, 8, and 12 months. Conclusion IPT is an effective treatment for late-life depression whose greater use by primary care physicians should be encouraged. Copyright © 2006 John Wiley & Sons, Ltd. [source] Clinical medication review by a pharmacist of elderly people living in care homes: pharmacist interventionsINTERNATIONAL JOURNAL OF PHARMACY PRACTICE, Issue 2 2007David P Alldred research clinical pharmacist Objectives To describe the rate and nature of pharmacist interventions following clinical medication review of elderly people living in care homes. Setting Care home residents aged 65+ years, prescribed at least one repeat medication, living in nursing, residential and mixed care homes for older people in Leeds, UK. Method Analysis of data from care home residents receiving clinical medication review in the intervention arm of a randomised controlled trial. Intervention outcomes for each medicine were evaluated for each resident. Key findings Three-hundred and thirty-one residents were randomised to receive a clinical medication review and 315 (95%) were reviewed by the study pharmacist; 256 (77%) residents had at least one recommendation made to the general practitioner. For the 2280 medicines prescribed, there were 672 medicine-related interventions: medicines for cardiovascular system (167 (25%)), nutrition and blood (121 (18%)), central nervous system (113 (17%)) and gastrointestinal conditions (86 (13%)) accounted for 487 (73%) of medicine-related interventions. There were 75 non-medicine-related interventions. The most common interventions were ,technical' (225 (30%)), ,test to monitor medicine' (161 (22%)), ,stop drug' (100 (13%)), ,test to monitor conditions' (75 (10%)), ,start drug' (76 (10%)), ,alter dose' (40 (5%)) and ,switch drug' (37 (5%)). Recommendations to stop a medicine were most common for CNS drugs (32 (32%)). The most common medicine to be recommended to be started was calcium and vitamin D (45 (59%)). Following a recommendation to test to monitor a medicine, 23 (14%) medicines required a change. Conclusions This study has demonstrated that clinical medication review by a pharmacist can identify medicine problems in approximately 80% of care home residents, requiring intervention in 1 in 4 of their prescribed medications. [source] Drug-related problems in elderly general practice patients receiving pharmaceutical careINTERNATIONAL JOURNAL OF PHARMACY PRACTICE, Issue 3 2005Elaine Lau Research fellow Objective To describe the types of drug-related problems identified by pharmacists providing pharmaceutical care to elderly patients in the primary care or general medicine setting, and the impact of their recommendations on drug-related outcomes. Methods Searches of the MEDLINE, EMBASE, CINAHL, HealthSTAR, and International Pharmaceutical Abstracts electronic databases from 1990 to 2002 were conducted and a manual search of references from retrieved articles and references on file was performed. Large (n> 100) randomised, controlled studies comparing the provision of pharmaceutical care to usual care in seniors in primary care or general medicine settings were included. Two reviewers evaluated articles based on inclusion criteria and extracted data from the intervention arm of each study, resolving discrepancies by consensus. Nine original articles were included for analysis. Key findings The mean number of drug-related problems (DRPs) identified per patient was 3.2 and the mean number of recommendations made per patient was 3.3. The most common DRP identified was not taking/receiving a prescribed drug appropriately (35.2%, range 4.7,49.3%). The most common recommendations made involved patient education (37.2%, range 4.6,48.2%). Implementation rates were generally high for all types of recommendations, with the highest being for provision of patient education (81.6%). The small number of studies available examining measures of drug utilisation and costs, health services utilisation, and patient outcomes produced inconsistent results, making it difficult to draw conclusions. Conclusions Substantial numbers and a wide range of DRPs were identified by pharmacists who provided pharmaceutical care to seniors in the primary care and general medicine setting. Pharmacists' drug-therapy recommendations were well accepted; however, further study is needed to determine the impact of these recommendations on health-related outcomes. [source] Postdischarge nursing interventions for stroke survivors and their familiesJOURNAL OF ADVANCED NURSING, Issue 2 2004Kelly L. McBride MSc RN Background. The physical, cognitive, and emotional sequelae of stroke underscore the need for nursing interventions across the continuum of care. Although there are several published studies evaluating community interventions for stroke survivors, the nursing role has not been clearly articulated. Aim. The aim of this paper is to report a study to describe, using a standardized classification system, the nursing interventions used with stroke survivors during the initial 6 weeks following discharge home. Methods. In the context of a randomized controlled trial, two nurse case managers provided care to 90 community-dwelling stroke survivors who were assigned to the intervention arm of the trial. The nursing documentation was analysed, using the Nursing Intervention Classification (NIC) system, to identify and quantify the interventions that were provided. Findings. Stroke survivors received, on average, six different interventions. There was a trend for those who were older, more impaired, and who lived alone to receive more interventions. The most commonly reported interventions included those directed towards ensuring continuity of care between acute and community care, family care, and modifying stroke risk factors. The study was limited to the nursing documentation, which may represent an underestimation of the care delivered. Conclusions. The NIC system was useful in capturing the interventions delivered by the nurse case managers. Nursing interventions are often not clearly articulated and less often use standardized terminology. Describing nursing activities in a standard manner will contribute to an increase in nursing knowledge and to evidence-based practice. [source] The effectiveness and reliability of peer-marking in first-year medical studentsMEDICAL EDUCATION, Issue 10 2006Rachel English Background, Peer-marking has been suggested as a method to enhance self-directed learning and reflection, although whether this improves performance is unclear. This study evaluated the impact of peer-marking on examination performance and investigated its reliability and acceptability to students. Methods, First-year medical students were randomised to peer-marking using a model answer or no intervention (control arm). Student scores were compared with tutor-marked scores. Two months later, students completed a summative assessment and performance was compared between students randomised to peer-marking and the control arm. A focus group was held with students in the intervention arm to capture their experiences and attitudes. Results, A total of 289 of 568 students consented to participate and 147 were randomised to peer-marking (142 controls). Students randomised to peer-marking achieved marginally higher examination marks (1.5% difference, 95% CI ,0.8% to 3.9%, P = 0.19) than controls (adjusting for year and in-course assessment), although this may have been due to chance. Students were harsher markers than the tutors. Focus group analysis suggested that students valued peer-marking, although concerns about passing judgement on a colleague's work were expressed. Conclusions, Peer-marking did not have a substantial effect on examination performance, although a modest effect cannot be excluded. Students gained insight into examination technique but may not have gained deeper knowledge. Given its potential positive educational value, further work is required to understand how peer-marking can be used more effectively to enhance the learning experience. [source] Can rational prescribing be improved by an outcome-based educational approach?THE JOURNAL OF CONTINUING EDUCATION IN THE HEALTH PROFESSIONS, Issue 1 2010A randomized trial completed in Iran Abstract Introduction: An outcome-based education approach has been proposed to develop more effective continuing medical education (CME) programs. We have used this approach in developing an outcome-based educational intervention for general physicians working in primary care (GPs) and evaluated its effectiveness compared with a concurrent CME program in the field of rational prescribing. Methods: A cluster randomized controlled design was used. All 159 GPs working in 6 cities, in 2 regions in East Azerbaijan province in Iran, were invited to participate. The cities were matched and randomly divided into an intervention arm, for an outcome-based education on rational prescribing, and a control arm for a traditional CME program on the same topic. GPs' prescribing behavior was assessed 9 months before, and 3 months after the CME programs. Results: In total, 112 GPs participated. The GPs in the intervention arm significantly reduced the total number of prescribed drugs and the number of injections per prescription. The GPs in the intervention arm also increased their compliance with specific requirements for a correct prescription, such as explanation of specific time and manner of intake and precautions necessary when using drugs, with significant intervention effects of 13, 36, and 42 percentage units, respectively. Compared with the control arm, there was no significant improvement when prescribing antibiotics and anti-inflammatory agents. Discussion: Rational prescribing improved in some of the important outcome-based indicators, but several indicators were still suboptimal. The introduction of an outcome-based approach in CME seems promising when creating programs to improve GPs' prescribing behavior. [source] The impact of psoriasis guidelines on appropriateness of referral from primary to secondary care: a randomized controlled trialBRITISH JOURNAL OF DERMATOLOGY, Issue 2 2006C.E.M. Griffiths Summary Background, Most patients with psoriasis have limited disease which can be managed effectively in primary care. There is a marked variation in the frequency of referrals between practices reflecting, in part, inadequate training of general practitioners (GPs) in the management of psoriasis. Objectives, To assess the effectiveness of guidelines and training sessions on the management of psoriasis in reducing inappropriate referrals from primary care. Methods, Patients aged 18 years or over with psoriasis were eligible for the cluster-randomized, randomized controlled trial if they were referred by their GP between 9 September 2002 and 31 December 2003 to one of four hospital dermatology departments in Greater Manchester, North-West England. All GPs from 165 health centres were invited to a lecture by a local dermatologist on the diagnosis and management of psoriasis. Health centres in the intervention arm received guidelines on the management of psoriasis in primary care, developed by local dermatologists, supplemented by the offer of a practice-based nurse-led training session; those in the control arm received neither guidelines nor training sessions. Results, Eighty-two health centres were randomized to the intervention arm and 83 to the control arm. Outcome data were available for 188 of the 196 eligible patients referred during the study period. Patients in the intervention arm were significantly more likely to be appropriately referred in comparison with patients in the control arm [difference = 19·1%; odds ratio (OR) 2·47; 95% confidence interval (CI) 1·31,4·68; intracluster correlation coefficient (ICC) = 0]. Only 25 (30%) health centres in the intervention arm took up the offer of training sessions. There was no significant difference in outcome between health centres in the intervention arm that received a training session and those that did not (OR 1·28, 95% CI 0·50,3·29, ICC = 0). Conclusions, Dissemination of guidelines on the management of psoriasis in primary care can significantly enhance the appropriateness of referral of patients to secondary care. [source] Cost-effectiveness of targeted and tailored interventions on colorectal cancer screening useCANCER, Issue 4 2008David R. Lairson PhD Abstract BACKGROUND. Colorectal cancer (CRC) screening is cost-effective but underused. The objective of this study was to determine the cost-effectiveness of targeted and tailored behavioral interventions to increase CRC screening use by conducting an economic analysis associated with a randomized trial among patients in a large, racially and ethnically diverse, urban family practice in Philadelphia. METHODS. The incremental costs per unit increase were measured in individuals who were screened during the 24 months after intervention. Percent increase in screening was adjusted for baseline differences in the study groups. Each intervention arm received a targeted screening invitation letter, stool blood test (SBT) cards, informational booklet, and reminder letter. Tailored interventions incrementally added tailored messages and reminder telephone calls. RESULTS. Program costs of the targeted intervention were $42 per participant. Additional costs of adding tailored print materials and of delivering a reminder telephone call were $150 and $200 per participant, respectively. The cost per additional individual screened was $319 when comparing the no intervention group with the targeted intervention group. CONCLUSIONS. The targeted intervention was more effective and less costly than the tailored intervention. Although tailoring plus reminder telephone call was the most effective strategy, it was very costly per additional individual screened. Mailed SBT cards significantly boosted CRC screening use. However, going beyond the targeted intervention to include tailoring or tailoring plus reminder calls in the manner used in this study did not appear to be an economically attractive strategy.

[source] Exercise parameters in the treatment of clinical depression: a systematic review of randomized controlled trialsJOURNAL OF EVALUATION IN CLINICAL PRACTICE, Issue 3 2010Luke G. Perraton BPT MPT Abstract Rationale, aims and objectives, Previous systematic reviews have concluded that exercise programmes are effective in the management of clinical depression. The aim of this review was to analyse the parameters of exercise programmes reported in the primary research, in order to provide clinicians with evidence-based recommendations for exercise prescription for clinical depression. Methods, A systematic review of randomized controlled trials was undertaken. Only trials that reported exercise to be effective in treating depression were included and our review was limited to adults. Appropriate databases and reference lists were searched using established keywords. Data relating to the type, intensity, frequency, duration, mode of exercise and mode of application of exercise was extracted and collated. Results, A total of 14 randomized controlled trials were included in this review and from these trials 20 intervention arms were analysed. The majority of trials used an aerobic exercise intervention and were supervised. The most common exercise parameters were 60,80% of maximum heart rate for 30 minutes three times per week for an overall duration of 8 weeks. There is an equal volume of evidence supporting group as opposed to individually completed exercise programmes and no trends were identified which would support one mode of exercise over another. Conclusions, Currently the primary research on this topic supports the use of aerobic exercise which is supervised in some capacity. The current evidence base supports a prescription of three 30-minute sessions per week of aerobic exercise at 60,80% of maximum heart rate for at least 8 weeks. [source] | ||||||||||
