Effectiveness of diclofenac versus paracetamol in knee osteoarthritis: a randomised controlled trial in primary care

Background

The effectiveness of diclofenac versus paracetamol in primary care patients with pain caused by knee osteoarthritis is unclear.

Aim

To assess the effectiveness of diclofenac compared with paracetamol over a period of 2, 4, and 12 weeks in patients with knee osteoarthritis.

Design and setting

Randomised controlled trial in general practice.

Method

There were 104 patients included in the study, they were aged ≥45 years consulting their GP with knee pain caused by knee osteoarthritis. Patients were randomly allocated to diclofenac (n = 52) or paracetamol (n = 52) for at least 2 weeks. Primary outcomes were daily knee pain severity, and knee pain and function measured with the Knee Injury and Osteoarthritis Outcome Score (KOOS).

Results

Over a period of 2- and 4-weeks follow-up, no significant difference in daily knee pain was found between the patient groups: estimated differences of 0.5 (95% CI = −0.2 to 1.3) and −0.2 (95% CI = −1.0 to 0.7), respectively. Over the 12-weeks follow-up, no significant differences were found between both groups for KOOS pain: estimated difference of −2.8 (95% CI = −10.7 to 5.1) and KOOS function of −2.7 (−10.6 to 5.0).

Conclusion

Over a period of 2- and 4-weeks follow-up no significant difference in daily measured knee pain severity was found between primary care patients with knee osteoarthritis taking paracetamol or diclofenac. Also, over a period of 12-weeks follow-up no significant differences were found regarding KOOS pain and KOOS function between both groups. Patients more frequently reported minor adverse events after taking diclofenac (64%) than paracetamol (46%).     

Reducing the time before consulting with symptoms of lung cancer: a randomised controlled trial in primary care

Background

Most individuals with lung cancer have symptoms for several months before presenting to their GP. Earlier consulting may improve survival.

Aim

To evaluate whether a theory-based primary care intervention increased timely consulting of individuals with symptoms of lung cancer.

Design and setting

Open randomised controlled trial comparing intervention with usual care in two general practices in north-east Scotland.

Method

Smokers and ex-smokers aged ≥55 years were randomised to receive a behavioural intervention or usual care. The intervention comprised a single nurse consultation at participants’ general practice and a self-help manual. The main outcomes were consultations within target times for individuals with new chest symptoms (≤3 days haemoptysis, ≤3 weeks other symptoms) in the year after the intervention commenced, and intentions about consulting with chest symptoms at 1 and 6 months.

Results

Two hundred and twelve participants were randomised and 206 completed the trial. The consultation rate for new chest symptoms in the intervention group was 1.19 (95% confidence interval [CI] = 0.92 to 1.53; P = 0.18) times higher than in the usual-care group and the proportion of consultations within the target time was 1.11 (95% CI = 0.41 to 3.03; P = 0.83) times higher. One month after the intervention commenced, the intervention group reported intending to consult with chest symptoms 31 days (95% CI = 7 to 54; P = 0.012) earlier than the usual care group, and at 6 months this was 25 days (95% CI = 1.5 to 48; P = 0.037) earlier.

Conclusion

Behavioural intervention in primary care shortened the time individuals at high risk of lung disease intended to take before consulting with new chest symptoms (the secondary outcome of the study), but increases in consultation rates and the proportions of consultations within target times were not statistically significant.     

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.     

Open Access Tubal aSsessment for the initial management of infertility in general practice (the OATS trial): a pragmatic cluster randomised controlled trial

Background

GPs investigate approximately half of all infertile couples with semen analysis and endocrine blood tests. For assessment of tubal status, hysterosalpingography (HSG) is recommended as a first-line investigation for women not known to have comorbidities.

Aim

To test whether providing GPs with open access to HSG results in infertile couples progressing to a diagnosis and management plan sooner than with usual management.

Design of study

A pragmatic cluster randomised controlled trial.

Setting

Seventy-one of 173 general practices in north-east England agreed to participate.

Method

A total of 670 infertile couples presented to 33 intervention practices and 25 control practices over a 2-year period. Practices allocated to the intervention group had access to HSG for those infertile women who fulfilled predefined eligibility criteria. The primary outcome measure was the interval between presentation to the GP and the couple receiving a diagnosis and management plan.

Results

An annual incidence of 0.8 couples per 1000 total population equated to each GP seeing an average of one or two infertile couples each year. Open access HSG was used for 9% of all infertile women who presented to the intervention practices during the study period. The time to reach a diagnosis and management plan for all infertile couples presenting was not affected by the availability of open access HSG (Cox regression hazard ratio = 0.9, 95% confidence interval [CI] = 0.7 to 1.1). For couples who reached a diagnosis and management plan, there was a non-significant difference in time to primary outcome for intervention versus control practices (32.5 weeks versus 30.5 weeks, mean difference 2.2 weeks, 95% CI = 1.6 to 6.1 weeks, P = 0.1). The intracluster correlation coefficient was 0.03 across all practices.

Conclusion

Providing GPs with open access to HSG had no effect on the time taken to reach a diagnosis and management plan for couples with infertility.     

A randomised controlled trial to test the feasibility of a collaborative care model for the management of depression in older people

BACKGROUND: Depression is the most common mental health disorder in people aged over 65 years. Late-life depression is associated with chronic illness and disability. AIM: To investigate the feasibility of a collaborative care model for depression in older people in a primary care setting. DESIGN OF STUDY: Randomised controlled trial with 16-weeks follow up. SETTING: A primary care trust in Manchester. METHOD: Participants were 105 people aged 60 years or older who scored 5 or more on the Geriatric Depression Scale; 53 were randomly allocated to an intervention group and 52 to a usual care group. The intervention group received care managed by a community psychiatric nurse who delivered an intervention comprising a facilitated self-help programme with close liaison with primary care professionals and old-age psychiatry according to a defined protocol. The usual care group received usual GP care. A nested qualitative study explored the views of the health professionals and patients regarding the acceptability and effectiveness of the intervention. RESULTS: The main outcome measure was recovery from depression. Patients in the intervention group were less likely to suffer from major depressive disorder at follow up compared with usual care (0.32, 95% confidence = interval = 0.11 to 0.93, P = 0.036). The qualitative component of the study demonstrated the acceptability of the intervention to patients. CONCLUSION: A model of collaborative care for older people with depression, used in a primary care setting with a facilitated self-help intervention is more effective than usual GP care. This study demonstrates that the implementation of a collaborative care model is feasible in UK primary care and that the intervention is effective and acceptable to patients.     

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.     

Comparison of methadone and buprenorphine for opiate detoxification (LEEDS trial): a randomised controlled trial

Background

Many opiate users require prescribed medication to help them achieve abstinence, commonly taking the form of a detoxification regime. In UK prisons, drug users are nearly universally treated for their opiate use by primary care clinicians, and once released access GP services where 40% of practices now treat drug users. There is a paucity of evidence evaluating methadone and buprenorphine (the two most commonly prescribed agents in the UK) for opiate detoxification.

Aim

To evaluate whether buprenorphine or methadone help to achieve drug abstinence at completion of a reducing regimen for heroin users presenting to UK prison health care for detoxification.

Design

Open-label, pragmatic, randomised controlled trial in three prison primary healthcare departments in the north of England.

Method

Prisoners (n = 306) using illicit opiates were recruited and given daily sublingual buprenorphine or oral methadone, in the context of routine care, over a standard reduced regimen of not more than 20 days. The primary outcome measure was abstinence from illicit opiates at 8 days post detoxification, as indicated by urine test (self-report/clinical notes where urine sample was not feasible). Secondary outcomes were also recorded.

Results

Abstinence was ascertained for 73.7% at 8 days post detoxification (urine sample = 52.6%, self report = 15.2%, clinical notes = 5.9%). There was no statistically significant difference in the odds of achieving abstinence between methadone and buprenorphine (odds ratio [OR] = 1.69; 95% confidence interval [CI] = 0.81 to 3.51; P = 0.163). Abstinence was associated solely with whether or not the participant was still in prison at that time (15.22 times the odds; 95% CI = 4.19 to 55.28). The strongest association for lasting abstinence was abstinence at an earlier time point.

Conclusion

There is equal clinical effectiveness between methadone and buprenorphine in achieving abstinence from opiates at 8 days post detoxification within prison.     

Simplified sleep restriction for insomnia in general practice: a randomised controlled trial

Background

Insomnia is common in primary care. Cognitive behavioural therapy for insomnia (CBT-I) is effective but requires more time than is available in the general practice consultation. Sleep restriction is one behavioural component of CBT-I.

Aim

To assess whether simplified sleep restriction (SSR) can be effective in improving sleep in primary insomnia.

Design and setting

Randomised controlled trial of patients in urban general practice settings in Auckland, New Zealand.

Method

Adults with persistent primary insomnia and no mental health or significant comorbidity were eligible. Intervention patients received SSR instructions and sleep hygiene advice. Control patients received sleep hygiene advice alone. Primary outcomes included change in sleep quality at 6 months measured by the Pittsburgh Sleep Quality Index (PSQI), Insomnia Severity Index (ISI), and sleep efficiency (SE%). The proportion of participants reaching a predefined ‘insomnia remission’ treatment response was calculated.

Results

Ninety-seven patients were randomised and 94 (97%) completed the study. At 6-month follow-up, SSR participants had improved PSQI scores (6.2 versus 8.4, P<0.001), ISI scores (8.6 versus 11.1, P = 0.001), actigraphy-assessed SE% (difference 2.2%, P = 0.006), and reduced fatigue (difference −2.3 units, P = 0.04), compared with controls. SSR produced higher rates of treatment response (67% [28 out of 42] versus 41% [20 out of 49]); number needed to treat = 4 (95% CI = 2.0 to 19.0). Controlling for age, sex, and severity of insomnia, the adjusted odds ratio for insomnia remission was 2.7 (95% CI = 1.1 to 6.5). There were no significant differences in other outcomes or adverse effects.

Conclusion

SSR is an effective brief intervention in adults with primary insomnia and no comorbidities, suitable for use in general practice.     

Case finding for chronic obstructive pulmonary disease in primary care: a pilot randomised controlled trial

Background

Chronic obstructive pulmonary disease (COPD) is a major cause of morbidity and mortality. However, much of the disease burden remains undiagnosed.

Aim

To compare the yield and cost effectiveness of two COPD case-finding approaches in primary care.

Design and setting

Pilot randomised controlled trial in two general practices in the West Midlands, UK.

Method

A total of 1634 ever-smokers aged 35–79 years with no history of COPD or asthma were randomised into either a ‘targeted’ or ‘opportunistic’ case-finding arm. Respiratory questionnaires were posted to patients in the ‘targeted’ arm and provided to patients in the ‘opportunistic’ arm at routine GP appointments. Those reporting at least one chronic respiratory symptom were invited for spirometry. COPD was defined as pre-bronchodilator forced expiratory volume in 1 second/forced vital capacity (FEV1/FVC)<0.7 and FEV1<80% of predicted. Primary outcomes were the difference in the proportion of patients diagnosed with COPD and the cost per case detected.

Results

Twenty-six per cent (212/815) in the ‘targeted’ and 13.6% (111/819) in the ‘opportunistic’ arm responded to the questionnaire and 78.3% (166/212) and 73.0% (81/111), respectively, reported symptoms; 1.2% (10/815) and 0.7% (6/819) of patients in the ‘targeted’ and ‘opportunistic’ arms were diagnosed with COPD (difference in proportions = 0.5% [95% confidence interval {CI} = –0.5% to 3.08%]). Over a 12-month period, the ‘opportunistic’ case-finding yield could be improved to 1.95% (95% CI = 1.0% to 2.9%). The cost-per case detected was £424.56 in the ‘targeted’ and £242.20 in the ‘opportunistic’ arm.

Conclusion

Opportunistic case finding may be more effective and cost effective than targeting patients with a postal questionnaire alone. A larger randomised controlled trial with adequate sample size is required to test this.     

Supervised exercises for adults with acute lateral ankle sprain: a randomised controlled trial.

BACKGROUND: During the recovery period after acute ankle sprain, it is unclear whether conventional treatment should be supported by supervised exercise. AIM: To evaluate the short- and long-term effectiveness of conventional treatment combined with supervised exercises compared with conventional treatment alone in patients with an acute ankle sprain. DESIGN: Randomised controlled clinical trial. SETTING: A total of 32 Dutch general practices and the hospital emergency department. METHOD: Adults with an acute lateral ankle sprain consulting general practices or the hospital emergency department were allocated to either conventional treatment combined with supervised exercises or conventional treatment alone. Primary outcomes were subjective recovery (0-10 point scale) and the occurrence of a resprain. Measurements were carried out at intake, 4 weeks, 8 weeks, 3 months, and 1 year after injury. Data were analysed using intention-to-treat analyses. RESULTS: A total of 102 patients were enrolled and randomised to either conventional treatment alone or conventional treatment combined with supervised exercise. There was no significant difference between treatment groups concerning subjective recovery or occurrence of resprains after 3 months and 1-year of follow-up. CONCLUSION: Conventional treatment combined with supervised exercises compared to conventional treatment alone during the first year after an acute lateral ankle sprain does not lead to differences in the occurrence of resprains or in subjective recovery.     

Motivational interviewing for modifying diabetes risk: a randomised controlled trial

BACKGROUND: Around 10-15% of adults aged over 40 years have pre-diabetes, which carries a high risk of progression to type 2 diabetes. Intensive lifestyle intervention reduces progression by as much as 58%. However, the cost and personnel requirements of these interventions are major obstacles to delivery in NHS primary care. AIM: To assess the effectiveness of a low-cost intervention, delivered in primary care by non-NHS staff, to reduce the risk of diabetes through weight loss and physical activity. DESIGN OF STUDY: Pragmatic single-blind randomised controlled trial with researchers and statistician blinded to group allocation. SETTING: UK primary care. METHOD: One-hundred and forty-one participants with a body mass index of 28 kg/m2 or more, but without diabetes or heart disease, received either information leaflets or individual behavioural counselling using motivational interviewing techniques. The intervention was delivered by five counsellors recruited from the local community. The primary outcomes were the proportions of participants meeting predefined targets for weight loss (5%) and moderate physical activity (150 minutes/week) after 6 months. RESULTS: Using intention-to-treat analysis, more people in the intervention group achieved the weight-loss target (24% versus 7% for controls; odds ratio [OR]=3.96; 95% confidence interval [Cl]=1.4 to 11.4; number needed to treat [NNT]=6.1 (95% Cl=4 to 21). The proportion achieving the physical activity target did not increase significantly (38% versus 28% for controls; OR=1.6; 95% Cl=0.7 to 3.8). CONCLUSION: Short-term weight loss, at a level which, if sustained, is clinically meaningful for reducing diabetes risk, is achievable in primary care, without excessive use of NHS monetary or personnel resources.     

Promoting physical activity in older people in general practice: ProAct65+ cluster randomised controlled trial

Background

Regular physical activity reduces falls, hip fractures, and all-cause mortality, but physical activity levels are low in older age groups.

Aim

To evaluate two exercise programmes promoting physical activity among older people.

Design and setting

Pragmatic three-arm, parallel-design cluster randomised controlled trial involving 1256 people aged ≥65 years (of 20 507 invited) recruited from 43 general practices in London, Nottingham, and Derby.

Method

Practices were randomised to the class-based Falls Management Exercise programme (FaME), the home-based Otago Exercise Program (OEP), or usual care. The primary outcome was the proportion reaching the recommended physical activity target 12 months post-intervention. Secondary outcomes included falls, quality of life, balance confidence, and costs.

Results

In total, 49% of FaME participants reached the physical activity target compared with 38% for usual care (adjusted odds ratio 1.78, 95% confidence interval [CI] =1.11 to 2.87, P = 0.02). Differences between FaME and usual care persisted 24 months after intervention. There was no significant difference comparing those in the OEP (43% reaching target at 12 months) and usual-care arms. Participants in the FaME arm added around 15 minutes of moderate-to-vigorous physical activity per day to their baseline level; this group also had a significantly lower rate of falls (incident rate ratio 0.74, 95% CI = 0.55 to 0.99, P = 0.042). Balance confidence was significantly improved in both intervention arms. The mean cost per extra person achieving the physical activity target was £1740. Attrition and rates of adverse reactions were similar.

Conclusion

The FaME programme increases self-reported physical activity for at least 12 months post-intervention and reduces falls in people aged ≥65 years, but uptake is low. There was no statistically significant difference in reaching the target, or in falls, between the OEP and usual-care arms.     

A randomised controlled trial of lay-led self-management for people with multiple sclerosis

Objective

To determine the impact of the Chronic Disease Self-Management Course (CDSMC) on people with multiple sclerosis (MS).

Methods

2-group, randomised, controlled trial with Intervention Group (IG) and Waiting-List Control Group (WLCG). Additional data were collected from a Comparison Group (CG) who chose not to attend the CDSMC. Participants completed baseline questionnaires; IG participants attended the CDSMC immediately; all participants were assessed at 4-months and 12-months.

Results

216 baseline questionnaires were returned; 73% were female, mean age 51.1 years, mean disease duration 12.0 years. Results showed that the CDSMC had an impact on self-management self-efficacy (ES 0.30, p = 0.009 for the IG) and MSIS physical status (ES 0.12 for the IG, p = 0.005). There were no other statistically significant changes. However, trends towards improvement on depression (ES 0.21 for the IG, p = 0.05) and MS self-efficacy (ES 0.16 for the IG, p = 0.04) were noted. All improvements were maintained at 12-months. At baseline, CG participants were older, had longer disease duration (p < 0.01) and less anxiety (p = 0.009) compared to RCT participants.

Conclusion

The CDSMC provides some small positive effects for people with MS. Motivation to attend may be linked to psychological distress and disease duration.

Practice implications

The CDSMC may be of value for those with mild anxiety/depression who need extra support. Attendance early in the disease course is recommended.     

Early identification of palliative care patients in general practice: development of RADboud indicators for PAlliative Care Needs (RADPAC)

Background

According to the World Health Organization (WHO) definition, palliative care should be initiated in an early phase and not be restricted to terminal care. In the literature, no validated tools predicting the optimal timing for initiating palliative care have been determined.

Aim

The aim of this study was to systematically develop a tool for GPs with which they can identify patients with congestive heart failure (CHF), chronic obstructive pulmonary disease (COPD), and cancer respectively, who could benefit from proactive palliative care.

Design

A three-step procedure, including a literature review, focus group interviews with input from the multidisciplinary field of palliative healthcare professionals, and a modified Rand Delphi process with GPs.

Method

The three-step procedure was used to develop sets of indicators for the early identification of CHF, COPD, and cancer patients who could benefit from palliative care.

Results

Three comprehensive sets of indicators were developed to support GPs in identifying patients with CHF, COPD, and cancer in need of palliative care. For CHF, seven indicators were found: for example, frequent hospital admissions. For COPD, six indicators were found: such as, Karnofsky score ≤50%. For cancer, eight indicators were found: for example, worse prognosis of the primary tumour.

Conclusion

The RADboud indicators for PAlliative Care Needs (RADPAC) is the first tool developed from a combination of scientific evidence and practice experience that can help GPs in the identification of patients with CHF, COPD, or cancer, in need of palliative care. Applying the RADPAC facilitates the start of proactive palliative care and aims to improve the quality of palliative care in general practice.     

Effectiveness of GP access to magnetic resonance imaging of the knee: a randomised trial

Background

GPs commonly see patients with knee problems. Magnetic resonance imaging (MRI) of the knee is an accurate diagnostic test for meniscus and ligament injuries of the knee, but there is uncertainty about the appropriate use of MRI and when it should enter the diagnostic pathway for patients with these problems.

Aim

To assess the effectiveness of GP referral to early MRI and a provisional orthopaedic appointment, compared with referral to an orthopaedic specialist without prior MRI for patients with continuing knee problems.

Design of study

Pragmatic multicentre randomised trial with two parallel groups.

Setting

A total of 553 patients consulting their GP about a continuing knee problem were recruited from 163 general practices at 11 sites across the UK.

Method

Patients were randomised to MRI within 12 weeks of GP referral including a provisional orthopaedic appointment, or orthopaedic appointment without prior MRI within a maximum of 9 months from GP referral. The primary outcome measures were the Short Form 36-item (SF-36) physical functioning scale and the Knee Quality of Life 26-item Questionnaire (KQoL-26) at 6, 12, and 24 months.

Results

Patients randomised to MRI improved mean SF-36 physical functioning scores by 2.81 (95% confidence interval [CI] = −0.26 to 5.89) more than those referred to orthopaedics (P = 0.072). Patients randomised to MRI improved mean KQoL-26 physical functioning scores by 3.65 (95% CI = 1.03 to 6.28) more than controls (P = 0.007). There were no other significant differences.

Conclusion

GP access to MRI yielded small, but statistically significant, benefits in patients'' knee-related quality of life but non-significant improvements in physical functioning.     

Self-management support for moderate-to-severe chronic obstructive pulmonary disease: a pilot randomised controlled trial

Background

Better self management could improve quality of life (QoL) and reduce hospital admissions in chronic obstructive pulmonary disease (COPD), but the best way to promote it remains unclear.

Aim

To explore the feasibility, effectiveness and cost effectiveness of a novel, layperson-led, theoretically driven COPD self-management support programme.

Design and setting

Pilot randomised controlled trial in one UK primary care trust area.

Method

Patients with moderate to severe COPD were identified through primary care and randomised 2:1 to the 7-week-long, group intervention or usual care. Outcomes at baseline, 2, and 6 months included self-reported health, St George’s Respiratory Questionnaire (SGRQ), EuroQol, and exercise.

Results

Forty-four per cent responded to GP invitation, 116 were randomised: mean (standard deviation [SD]) age 69.5 (9.8) years, 46% male, 78% had unscheduled COPD care in the previous year. Forty per cent of intervention patients completed the course; 35% attended no sessions; and 78% participants completed the 6-month follow-up questionnaire. Results suggest that the intervention may increase both QoL (mean EQ-5D change 0.12 (95% confidence interval [CI] = –0.02 to 0.26) higher, intervention versus control) and exercise levels, but not SGRQ score. Economic analyses suggested that with thresholds of £20 000 per quality-adjusted life-year gained, the intervention is likely to be cost-effective.

Conclusion

This intervention has good potential to meet the UK National Institute for Health and Clinical Excellence criteria for cost effectiveness, and further research is warranted. However, to make a substantial impact on COPD self-management, it will also be necessary to explore other ways to enable patients to access self-management education.     

Coordination of care for individuals with advanced progressive conditions: a multi-site ethnographic and serial interview study

Background

Coordination of care for individuals with advanced progressive conditions is frequently poor.

Aim

To identify how care is coordinated in generalist settings for individuals with advanced progressive conditions in the last year of life.

Design and setting

A mixed methods study of three UK generalist clinical settings producing three parallel case studies: an acute admissions unit in a regional hospital, a large general practice, and a respiratory outpatient service.

Method

Ethnographic observations in each setting, followed by serial interviews of patients with advanced progressive conditions and their family carers in the community. A spectrum of clinicians and healthcare workers were also interviewed.

Results

Ethnographic observations were conducted for 22 weeks. A total of 56 patients, 25 family carers and 17 clinicians yielded 198 interviews. Very few participants had been identified for a palliative approach. Rapid throughput of hospital patients and time pressures in primary care hindered identification of palliative care needs. Lack of care coordination was evident during emergency admissions and discharges. Patient, families, and professionals identified multiple problems relating to lack of information, communication, and collaboration at care transitions. Family carers or specialist nurses, where present, usually acted as the main care coordinators.

Conclusion

Care is poorly coordinated in generalist settings for patients in the last year of life, although those with cancer have better coordinated care than other patients. A model to improve coordination of care for all individuals approaching the end of life must ensure that patients are identified in a timely way, so that they can be assessed and their care planned accordingly.     

Effectiveness of a community intervention on malaria in rural Tanzania - a randomised controlled trial

Background

Malaria infections are a major public health problem in Africa and prompt treatment is one way of controlling the disease and saving lives.

Methods

This cluster-randomised controlled community intervention conducted in 2003–2005 aimed at improving early malaria case management in under five children. Health workers were trained to train community-based women groups in recognizing malaria symptoms, providing first-line treatment for uncomplicated malaria and referring severe cases. Evaluation was through a pre- (2004) and a post-intervention survey (2005). Anaemia prevalence was the primary outcome.

Results

1715 children aged 6–59 months were included in the pre-intervention survey and 2169 in the post-intervention survey. The prevalence of anaemia decreased significantly from 37% [95% CI 34.7–39.3] to 0.5% [95% CI 0.2–0.7] after the intervention (p<0.001); slightly more in the intervention (from 43.9% to 0.8%) than in the control (30.8% to 0.17%) group (p=0.038). Fever and reported fever decreased significantly and the mean body weight of the children increased significantly over the study period in both control and intervention groups.

Conclusion

The decrease in anaemia was significantly associated with the intervention, whereas the fever and body weight trends might be explained by other malaria control activities or seasonal/climate effects in the area. The community intervention was shown to be feasible in the study context.     

Internet delivered support for tobacco control in dental practice: randomized controlled trial

Background

The dental visit is a unique opportunity for tobacco control. Despite evidence of effectiveness in dental settings, brief provider-delivered cessation advice is underutilized.

Objective

To evaluate an Internet-delivered intervention designed to increase implementation of brief provider advice for tobacco cessation in dental practice settings.

Methods

Dental practices (N = 190) were randomized to the intervention website or wait-list control. Pre-intervention and after 8 months of follow-up, each practice distributed exit cards (brief patient surveys assessing provider performance, completed immediately after the dental visit) to 100 patients. Based on these exit cards, we assessed: whether patients were asked about tobacco use (ASK) and, among tobacco users, whether they were advised to quit tobacco (ADVISE). All intervention practices with follow-up exit card data were analyzed as randomized regardless of whether they participated in the Internet-delivered intervention.

Results

Of the 190 practices randomized, 143 (75%) dental practices provided follow-up data. Intervention practices’ mean performance improved post-intervention by 4% on ASK (29% baseline, adjusted odds ratio = 1.29 [95% CI 1.17-1.42]), and by 11% on ADVISE (44% baseline, OR = 1.55 [95% CI 1.28-1.87]). Control practices improved by 3% on ASK (Adj. OR 1.18 [95% CI 1.07-1.29]) and did not significantly improve in ADVISE. A significant group-by-time interaction effect indicated that intervention practices improved more over the study period than control practices for ADVISE (P = 0.042) but not for ASK.

Conclusion

This low-intensity, easily disseminated intervention was successful in improving provider performance on advice to quit.
