The effect of educational intervention on intercultural communication: results of a randomised controlled trial

BACKGROUND: Due to worldwide migration to Western countries, physicians are increasingly encountering patients with different ethnic backgrounds. Communication problems can arise as a result of differences in cultural backgrounds and poor language proficiency. AIMS: To assess the effectiveness of an educational intervention on intercultural communication aimed to decrease inequalities in care provided between Western and non-Western patients. DESIGN OF STUDY: A randomised controlled trial with randomisation at the GP level and outcome measurements at the patient level. SETTING: General practice in Rotterdam. METHOD: Thirty-eight Dutch GPs in the Rotterdam region, with at least 25% of inhabitants of non-Western origin, and 2407 visiting patients were invited to participate in the study. A total of 986 consultations were finally included. The GPs were educated about cultural differences and trained in intercultural communication. Patients received a videotaped instruction focusing on how to communicate with their GP in a direct way. The primary outcome measure was mutual understanding and the secondary outcomes were patient's satisfaction and perceived quality of care. The intervention effect was assessed for all patients together, for the 'Western' and 'non-Western' patients, and for patients with different cultural backgrounds separately. RESULTS: An intervention effect was seen 6 months after the intervention, as improvement in mutual understanding (and some improvement in perceived quality of care) in consultations with 'non-Western' patients. CONCLUSIONS: A double intervention on intercultural communication given to both physician and patient decreases the gap in quality of care between 'Western' and 'non-Western' patients.     

Promoting brief alcohol intervention by nurses in primary care: a cluster randomised controlled trial

This trial evaluated the clinical impact and cost-effectiveness of strategies promoting screening and brief alcohol intervention (SBI) by nurses in primary care. Randomisation was at the level of the practice and the interventions were: written guidelines (controls, n=76); outreach training (n=68); and training plus telephone-based support (n=68). After 3 months, just 39% of controls implemented the SBI programme compared to 74% of nurses in trained practices and 71% in trained and supported practices. Controls also screened fewer patients and delivered fewer brief interventions to risk drinkers than other colleagues. However, there was a trade-off between the extent and the appropriateness of brief intervention delivery with controls displaying the least errors in overall patient management. Thus cost-effectiveness ratios (cost per patient appropriately treated) were similar between the three strategies. Given the potential for anxiety due to misdirected advice about alcohol-related risk, the balance of evidence favoured the use of written guidelines to promote SBI by nurses in primary care.     

Effects of an educational peer-group intervention on knowledge about dementia among family caregivers with a Turkish or Moroccan immigrant background: A cluster randomised controlled trial

ObjectiveThe aim of this paper is to examine the effects of an educational peer-group intervention on knowledge about dementia, perceived ability to talk about it, received support and self-perceived pressure from informal care among family caregivers with a Turkish or Moroccan immigrant background who cared for a person with dementia.MethodsThis paper is based on a cluster randomised controlled trial with three measures, including participants who knew or cared for a person with dementia. For the purpose of this study, a selection was made of participants who cared for a person with dementia. Knowledge about dementia, perceived ability to talk about dementia, support received and self-perceived pressure from informal care were assessed inthe intervention and the control condition. Multi-level analyses were conducted to examine the effects.ResultsData for 386 participants was analysed. Improvement in knowledge about dementia over time was significantly greater in the intervention condition than in the control condition. In the intervention condition, there was also a significant increase over time in the support received from home-care staff, which was not found in the control condition. No effects were found on other types of support received, the ability to talk about dementia or the self-perceived pressure from informal care.ConclusionOffering a culturally sensitive educational peer-group education intervention enhances knowledge about dementia and has a small but positive effect on the support received from home-care staff in these groups.Practice ImplicationsOffering peer-group-based education about dementia to family caregivers with Turkish or Moroccan immigrant backgrounds is important for multicultural dementia care.     

The effect of a brief social intervention on the examination results of UK medical students: a cluster randomised controlled trial

Background  

Ethnic minority (EM) medical students and doctors underperform academically, but little evidence exists on how to ameliorate the problem. Psychologists Cohen et al. recently demonstrated that a written self-affirmation intervention substantially improved EM adolescents' school grades several months later. Cohen et al.'s methods were replicated in the different setting of UK undergraduate medical education.     

A short educational intervention on communication skills improves the quality of screening for Chlamydia in GPs in Belgium: a cluster randomised controlled trial

An accurate algorithm for screening for chlamydial infections is available in general practice, but GPs experience numerous barriers to sexually transmitted infections (STI) counselling. In this study we assessed if a short educational package, under the form of a commented video footage on communication skills, was helpful in implementing the screening strategy. A cluster randomised controlled trial was carried out in 36 general practitioners in Antwerp, Belgium. Main outcome measures were: number of patients included in the risk assessment, number of patients tested, and proportion of appropriately tested patients. The results show that GPs in the intervention group did not include more patients overall, but that the quality of the screening process was significantly better (81.6% versus 56.2% appropriate tests, P = 0.02). Conclusively, GPs who participated in a short educational package on communication skills, selected eligible candidates for screening more accurately and decreased the risk of overscreening.     

Evaluation of an intervention to improve blood culture practices: a cluster randomised trial

This study aimed to evaluate an intervention to improve blood culture practices. A cluster randomised trial in two parallel groups was performed at the Grenoble University Hospital, France. In October 2009, the results of a practices audit and the guidelines for the optimal use of blood cultures were disseminated to clinical departments. We compared two types of information dissemination: simple presentation or presentation associated with an infectious diseases (ID) specialist intervention. The principal endpoint was blood culture performance measured by the rate of patients having one positive blood culture and the rate of positive blood cultures. The cases of 130 patients in the “ID” group and 119 patients in the “simple presentation” group were audited during the second audit in April 2010. The rate of patients with one positive blood culture increased in both groups (13.62 % vs 9.89 % for the ID group, p?=?0.002, 15.90 % vs 13.47 % for the simple presentation group, p?=?0.009). The rate of positive blood cultures improved in both groups (6.68 % vs 5.96 % for the ID group, p?=?0.003, 6.52 % vs 6.21 % for the simple presentation group, p?=?0.017). The blood culture indication was significantly less often specified in the request form in the simple presentation group, while it remained stable in the ID group (p?=?0.04). The rate of positive blood cultures and the rate of patients having one positive blood culture improved in both groups. The ID specialist intervention did not have more of an impact on practices than a simple presentation of audit feedback and guidelines.     

Feasibility of an exercise intervention for women with postnatal depression: a pilot randomised controlled trial.

BACKGROUND: Postnatal depression is a serious mental health problem that may be reduced by exercise. AIM: This study examined the feasibility of an exercise intervention for women with postnatal depression, and assessed which methods of recruitment are most effective. DESIGN OF STUDY: Randomised controlled trial. SETTING: General practice and the community. METHOD: Participants were recruited from various sources and randomised to an exercise intervention or usual care with follow-up at 12 weeks. As well as assessing feasibility, other trial outcomes included exercise participation and self-efficacy for exercise. Levels of depression were assessed but the study was not powered to show a difference in this. RESULTS: The recruitment rate of eligible patients was 23.1%. The highest recruitment rate was via referral from the psychiatric mother and baby unit (9/28; 32.1%), followed by invitation letters from GPs (24/93; 25.8%). Thirty-eight eligible participants were randomised. At follow-up there was no significant difference in exercise participation between groups. The intervention group reported significantly higher self-efficacy for exercise compared to usual care, but depression scores did not differ. CONCLUSION: Exercise participation over the 12-week period was not significantly increased, possibly because it is difficult to motivate women with postnatal depression to exercise, or the intervention was not sufficiently intensive. Eligible patients were recruited into this study but response rates were low. Optimum methods of recruitment in this difficult-to-reach population are required prior to a substantive trial. Further research is imperative given poorly-evidenced recommendations by the National Institute for Health and Clinical Excellence to consider this treatment.     

A pragmatic cluster randomized controlled trial of an educational intervention for GPs in the assessment and management of depression

BACKGROUND: General practitioners (GPs) can be provided with effective training in the skills to manage depression. However, it remains uncertain whether such training achieves health gain for their patients. METHOD: The study aimed to measure the health gain from training GPs in skills for the assessment and management of depression. The study design was a cluster randomized controlled trial. GP participants were assessed for recognition of psychological disorders, attitudes to depression, prescribing patterns and experience of psychiatry and communication skills training. They were then randomized to receive training at baseline or the end of the study. Patients selected by GPs were assessed at baseline, 3 and 12 months. The primary outcome was depression status, measured by HAM-D. Secondary outcomes were psychiatric symptoms (GHQ-12) quality of life (SF-36), satisfaction with consultations, and health service use and costs. RESULTS: Thirty-eight GPs were recruited and 36 (95%) completed the study. They selected 318 patients, of whom 189 (59%) were successfully recruited. At 3 months there were no significant differences between intervention and control patients on HAM-D, GHQ-12 or SF-36. At 12 months there was a positive training effect in two domains of the SF-36, but no differences in HAM-D, GHQ-12 or health care costs. Patients reported trained GPs as somewhat better at listening and understanding but not in the other aspects of satisfaction. CONCLUSIONS: Although training programmes may improve GPs' skills in managing depression, this does not appear to translate into health gain for depressed patients or the health service.     

Anxiety levels in women attending a colposcopy clinic: a randomised trial of an educational intervention using video colposcopy

A video colposcopy allows the real-time images viewed by the doctor performing the examination to be viewed by patients on a television monitor during the consultation. Eighty-one women (requiring either laser treatment or a normal recheck) were randomly assigned to either the video intervention group or the control group. A significant decrease in state anxiety was observed from one visit to the next in all patients (P = 0.000). This decrease in anxiety was significantly greater in the laser patients in the video colposcopy condition than patients in the control group for both groups of patients. Patients in the experimental groups also reported less pain than patients in the control conditions (P < 0.05). This benefit associated with video colposcopy was not observed on the second (treatment) visit. In conclusion, video colposcopy is a useful and time-efficient method that reduces patient anxiety and pain during examination visits, but not necessarily during visits where laser treatment is required.     

Effects of an educational intervention on health-related quality of life among family caregivers of people with dementia with a Turkish or Moroccan immigrant background: Insights from a cluster randomised controlled trial

ObjectiveGaining understanding of the health-related quality of life (HRQL) of family caregivers of people with dementia with Turkish or Moroccan immigrant backgrounds and to examine whether an educational peer group intervention can improve HRQL.MethodsUnderstanding of HRQL and associated variables was obtained by multiple linear regression analyses. The effects of the intervention on HRQL were assessed in multilevel analyses using data collected before the start (baseline), directly after the intervention (one to two weeks after baseline) and three months after the start of the intervention. The intervention (two interactive group sessions) entailed providing information about dementia and care/support options.ResultsAt baseline (n = 319), HRQL was moderately and significantly associated with migration background, gender, self-perceived pressure from informal care and the formal and informal support received (p < .05). The intervention had a small effect on emotional wellbeing directly after the intervention (p < .05) and on perceived general health status three months after (p < .05).ConclusionCulturally sensitive peer group education on dementia and care/support options can to some extent enhance HRQL among family caregivers in the short term.Practice implicationsThe intervention as described in this study is recommended for supporting family caregivers of people with dementia with Turkish or Moroccan backgrounds.     

REDIRECT: cluster randomised controlled trial of GP training in first-episode psychosis

Background

Delays in accessing care for young people with a first episode of psychosis are significantly associated with poorer treatment response and higher relapse rates.

Aim

To assess the effect of an educational intervention for GPs on referral rates to early-intervention services and the duration of untreated psychosis for young people with first-episode psychosis.

Design of study

Stratified cluster randomised controlled trial, clustered at practice level.

Setting

Birmingham, England.

Method

Practices with access to the three early-intervention services in three inner-city primary care trusts in Birmingham were eligible for inclusion. Intervention practices received an educational intervention addressing GP knowledge, skills, and attitudes about first-episode psychosis. The primary outcome was the difference in the number of referrals to early-intervention services between practices. Secondary outcomes were duration of untreated psychosis, time to recovery, use of the Mental Health Act, and GP consultation rate during the developing illness.

Results

A total of 110 of 135 eligible practices (81%) were recruited; 179 young people were referred, 97 from intervention and 82 from control practices. The relative risk of referral was not significant: 1.20 (95% confidence interval [CI] = 0.74 to 1.95; P = 0.48). No effect was observed on secondary outcomes except for ‘delay in reaching early-intervention services’, which was statistically significantly shorter in patients registered in intervention practices (95% CI = 83.5 to 360.5; P = 0.002).

Conclusion

GP training on first-episode psychosis is insufficient to alter referral rates to early-intervention services or reduce the duration of untreated psychosis; however, there is a suggestion that training facilitates access to the new specialist teams for early psychosis.     

Implementation of RCGP guidelines for acute low back pain: a cluster randomised controlled trial.

BACKGROUND: The Royal College of General Practitioners (RCGP) has produced guidelines for the management of acute low back pain in primary care. AIM: To investigate the impact on patient management of an educational strategy to promote these guidelines among general practitioners (GPs). DESIGN OF STUDY: Group randomised controlled trial, using the health centre as the unit of randomisation. SETTING: Primary care teams in north-west England. METHOD: Twenty-four health centres were randomly allocated to an intervention or control arm. Practices in the intervention arm were offered outreach visits to promote national guidelines on acute low back pain, as well as access to fast-track physiotherapy and to a triage service for patients with persistent symptoms. RESULTS: Twenty-four centres were randomised. Two thousand, one hundred and eighty-seven eligible patients presented with acute low back pain during the study period: 1049 in the intervention group and 1138 in the control group. There were no significant differences between study groups in the proportion of patients who were referred for X-ray, issued with a sickness certificate, prescribed opioids or muscle relaxants, or who were referred to secondary care, but significantly more patients in the intervention group were referred to physiotherapy or the back pain unit (difference in proportion = 12.2%, 95% confidence interval [CI] = 2.8% to 21.6%). CONCLUSION: The management of patients presenting with low back pain to primary care was mostly unchanged by an outreach educational strategy to promote greater adherence to RCGP guidelines among GPs. An increase in referral to physiotherapy or educational programmes followed the provision of a triage service.     

Successful GP intervention with frequent attenders in primary care: randomised controlled trial.

BACKGROUND: Frequent attenders to GP clinics can place an unnecessary burden on primary care. Interventions to reduce frequent attendance have had mixed results. AIM: To assess the effectiveness of a GP intervention to reduce frequent-attender consultations. DESIGN OF STUDY: Randomised controlled trial with frequent attenders divided into an intervention group and two control groups (one control group was seen by GPs also providing care to patients undergoing the intervention). SETTING: A health centre in southern Spain. METHOD: Six GPs and 209 randomly-selected frequent attenders participated. Three GPs were randomly allocated to perform the new intervention: of the 137 frequent attenders registered with these three GPs, 66 were randomly allocated to receive the intervention (IG) and 71 to a usual care control group (CG2). The other three GPs offered usual care to the other 72 frequent attenders (CG1). The main outcome measure was the total number of consultations 1 year post-intervention. Baseline measurements were recorded of sociodemographic characteristics, provider-user interface, chronic illnesses, and psychosocial variables. GPs allocated to the new intervention received 15 hours' training which incorporated biopsychosocial, organisational, and relational approaches. After 1 year of follow-up frequent attenders were contacted. An intention-to-treat analysis was used. RESULTS: A multilevel model was built with three factors: time, patient, and doctor. After adjusting for covariates, the mean number of visits at 1 year in IG was 13.10 (95% confidence interval [CI]=11.39 to 14.94); in the CG1 group was 19.37 (95% CI=17.31 to 21.55); and in the CG2 group this was 16.72 (95% CI=4.84 to 18.72). CONCLUSION: The new intervention with GPs resulted in a significant and relevant reduction in frequent-attender consultations. Although further trials are needed, this intervention is recommended to GPs interested in reducing consultations by their frequent attenders.     

Evaluation of the impact of two educational interventions on GP management of familial breast/ovarian cancer cases: a cluster randomised controlled trial.

BACKGROUND: It has been suggested that primary care should become more involved in providing genetic services, such as basic risk assessment, to enable patients with a moderate/high risk to be referred and those with a low risk to receive reassurance and advice from their general practitioner (GP). However, GPs currently lack knowledge and confidence in this area. AIM: To investigate the effect of an in-practice educational session and information pack on GP management of familial breast/ovarian cancer cases. DESIGN OF STUDY: Cluster randomised controlled trial. SETTING: GP principals in 170 practices in Oxfordshire and Northamptonshire. Of the 688 GPs, 426 (62%) participated. METHOD: Practices were randomised either to Group A (receiving an inpractice educational session plus information pack), Group B (receiving an information pack alone), or Group C (receiving neither an educational session nor a pack). The main study outcome was the proportion of GPs making the correct referral decision on at least five out of six family history vignettes. A secondary outcome was GPs' reported confidence in managing patients with a family history of breast/ovarian cancer, measured by a score that was generated by combining responses to four questions. RESULTS: There was a 40% (95% CI = 30-50%, P < 0.001) improvement in the proportion of GPs who made the correct referral decision on at least five out of the six vignettes in Group A (111/140 [79%]) compared with Group C (controls) (63/162 [39%]), and a 42% (95% CI = 31-52%, P < 0.001) improvement in Group B (100/124 [81%]) compared with the control group. There was a trend in reported confidence in the management of individuals with a family history of breast/ovarian cancer from a mean confidence score of 2.3 in Group A to 2.0 in Group B and 1.5 in Group C (P < 0.001). CONCLUSION: Providing GPs with an information pack significantly improved referral decisions regarding patients with a family history of breast/ovarian cancer. Although extremely well received, an in-house educational session produced no additional improvements. There were, however, greater levels of reported confidence in the group who received the educational session in addition to the information pack.     

Creating a synergy effect: A cluster randomized controlled trial testing the effect of a tailored multimedia intervention on patient outcomes

Objective

Improving adherence is a challenge and multiple barriers are likely to explain non-adherence. These barriers differ per patient and over course of the regimen. Hence, personalized interventions tailored to the specific barriers are needed. In a theoretical and evidence-based Tailored Multimedia Intervention, technology (online preparatory assessment, text messaging) was used as an add-on to a tailored counseling session (learned during a communication skills training), with the expectation of synergistic effects.

Giving patients an audiotape of their GP consultation: a randomised controlled trial.

BACKGROUND: Providing patients with an audiotape of their medical consultation has been a relatively common practice in oncology clinics for some years. However, broader generalisability of the technique has yet to be examined. AIMS: To investigate the efficacy of providing patients with an audiotape of their consultation in a general practice setting. DESIGN OF STUDY: Randomised controlled trial: 95 experimental participants, 85 controls. SETTING: Routine surgeries run by two general practitioners (GPs) in two different health centres. METHOD: All patients attending GP appointments were eligible for inclusion. Patients were followed up by telephone 7-10 days later. RESULTS: More than half (61%) of the patients who received a tape listened to it. Among listeners, 64% rated the tape useful or very useful; 24% noticed information not heard in the consultation. Half of listeners (46%) said that their understanding of the consultation improved after listening to the tape. Half of the listeners (48%) shared the tape with others, of whom 71% found sharing helpful or very helpful. However, 21% of those who shared the information with others found this unhelpful or very unhelpful, suggesting that patients may need to be briefed on the potential risks of sharing. At follow-up a week later, it emerged that being given a tape had no effect on adherence with GPs' advice, nor on anxiety about conditions. CONCLUSION: Providing patients with an audiotape of their GP consultation was positively rated by many patients. Although there were no detectable clinical effects at follow-up, the technique merits further evaluation in general practice.     

The DEBIT trial: an intervention to reduce antipsychotic polypharmacy prescribing in adult psychiatry wards - a cluster randomized controlled trial

BACKGROUND: Clinical guidelines advise against prescribing more than one antipsychotic with limited exceptions. Despite this, surveys continue to report high antipsychotic polypharmacy rates. The aim of the study was to investigate the effectiveness of a multi-faceted intervention in reducing prescribing of antipsychotic polypharmacy on general adult psychiatry wards, compared with guidelines alone. METHOD: A pragmatic cluster randomized controlled trial recruited 19 adult psychiatric units (clusters) from the South West of England. Participants were all ward doctors and nurses. The multi-faceted intervention comprised: an educational/CBT workbook; an educational visit to consultants; and a reminder system on medication charts. RESULTS: The odds of being prescribed antipsychotic polypharmacy in those patients prescribed antipsychotic medication was significantly lower in the intervention than control group when adjusted for confounders (OR 0.43, 95% CI 0.21-0.90, p=0.028). There was considerable between-unit variation in polypharmacy rates and in the change in rates between baseline and follow-up (5 months after baseline). CONCLUSION: The intervention reduced levels of polypharmacy prescribing compared to guidelines alone although the effect size was relatively modest. Further work is needed to elicit the factors that were active in changing prescribing behaviour.
