Community prevalence of long-term urinary catheters use in England

OBJECTIVES

To calculate the prevalence of long term catheter use in the community in two areas in the south and west of England.

SUBJECTS/PATIENTS (OR MATERIALS) AND METHODS

People in England register with general practices to access health care through a National Health Service. Catheters are provided by prescription free of charge. In 2008, patients using urinary catheters for over 3 months were identified, and demographic information collected, from databases of general practices, using catheter prescribing records. The age and sex distributions of people in each practice were obtained from capitation claims. Overall, and age and sex-specific prevalence were calculated separately for each area, and compared.

RESULTS

A total of 583 long term catheter users (329 south, 254 west) were identified from 404,328 people registered with practices. The overall population prevalence is similar in both locations (0.146% southern, 0.141% western). Extrapolating for the United Kingdom, this is over 90,000 long term catheter users. Prevalence increases with age (0.732% in over 70 years, 1.224% over 80), especially amongst men. Overall, higher proportions have neurological (vs. non-neurological) reasons (62.9% vs. 37.1%) and use urethral (vs. suprapubic) catheters (59.7% vs. 40.3%). Compared to men, more women tend to use suprapubic (56.4% vs. 29.3%) and have a catheter for neurological reasons (71.8% vs. 56.2%, P = 0.053).

CONCLUSIONS

Previous evidence on prevalence of long term catheter use is sparse, and of variable quality. The strength of this study is utilisation of a reliable source of data (catheter prescriptions) from a large population of patients. Neurourol. Urodynam. 36:293-296, 2017. © 2016 Wiley Periodicals, Inc.

The True NTH Prostate Cancer Survivorship Care programme: Development and evaluation of a model for delivering follow-up care to men with prostate cancer

42

Background: Increasing use of prostate specific antigen (PSA), improvements in treatment and aging population have led to the escalating incidence of prostate cancer. 5 year survival rate is relatively high and men who have completed treatment require long-term follow-up to detect recurrence or progression of disease, monitor adverse effects of treatment and identify and address psychosocial needs. Studies demonstrate men have a range of unmet physical and psychosocial needs, and health services are struggling to cope with the growing numbers. Changes is critical for long-term sustainability of the health system in many developed nations Methods: This presentation presents a model of follow up care centered on remote surveillance of PSA combined with promoting patient self-management. This initiative is part of the True NTH programme of developments initiated in the UK with funding from Movember Foundation and Prostate Cancer UK. Traditional face to face clinic follow up consultations are replaced with: patient directed individually tailored care and surveillance programme which involves: a 4 hour preparatory patient workshop, remote assessment of unmet needs and symptoms and surveillance of PSA, patient information resources, survivorship care plan, communication of treatment summary and management plan to primary care, and rapid recall system for assessment in secondary care should the need arise. The care programme is mediated through clinician and patient access to an IT portal enabling communication. Results: The second part of the presentation will describe the evaluation protocol. A historical cohort design is comparing a group of men receiving clinic follow up care (N = 300) with men enrolled on the care programme (N = 300) in 3 centers. Patient-reported outcomes are collected at baseline, 4 months and 8 months. Health economic evaluation will compare costs of clinic based follow up with those of the care programme from both a health service and patient perspective. Conclusions: The evaluation will generate data on impact, acceptability and cost of this model of follow-up care.

Feasibility study of an integrated stroke self-management programme: a cluster-randomised controlled trial

OBJECTIVES

To test the feasibility of conducting a controlled trial into the effectiveness of a self-management programme integrated into stroke rehabilitation.

DESIGN

A feasibility cluster-randomised design was utilised with stroke rehabilitation teams as units of randomisation.

SETTING

Community-based stroke rehabilitation teams in London.

PARTICIPANTS

78 patients with a diagnosis of stroke requiring community based rehabilitation.

INTERVENTION

The intervention consisted of an individualised approach to self-management based on self-efficacy. Clinicians were trained to integrate defined self-management principles into scheduled rehabilitation sessions, supported by a patient-held workbook.

MAIN OUTCOMES MEASURES

Patient measures of quality of life, mood, self-efficacy and functional capacity, and health and social care utilisation, were carried out by blinded assessors at baseline, 6 weeks and 12 weeks. Fidelity and acceptability of the delivery were evaluated by observation and interviews.

RESULTS

4 community stroke rehabilitation teams were recruited, and received a total of 317 stroke referrals over 14 months. Of these, 138 met trial eligibility criteria and 78 participants were finally recruited (56.5%). Demographic and baseline outcome measures were similar between intervention and control arms, with the exception of age. All outcome measures were feasible to use and clinical data at 12 weeks were completed for 66/78 participants (85%; 95% CI 75% to 92%). There was no significant difference in any of the outcomes between the arms of the trial, but measures of functional capacity and self-efficacy showed responsiveness to the intervention. Observation and interview data confirmed acceptability and fidelity of delivery according to predetermined criteria. Costs varied by site.

CONCLUSIONS

It was feasible to integrate a stroke self-management programme into community rehabilitation, using key principles. Some data were lost to follow-up, but overall results support the need for conducting further research in this area and provide data to support the design of a definitive trial.

Impact of a hospice rapid response service on preferred place of death, and costs

BACKGROUND

Many people with a terminal illness would prefer to die at home. A new palliative rapid response service (RRS) provided by a large hospice provider in South East England was evaluated (2010) to provide evidence of impact on achieving preferred place of death and costs. The RRS was delivered by a team of trained health care assistants and available 24/7. The purpose of this study was to (i) compare the characteristics of RRS users and non-users, (ii) explore differences in the proportions of users and non-users dying in the place of their choice, (iii) monitor the whole system service utilisation of users and non-users, and compare costs.

METHODS

All hospice patients who died with a preferred place of death recorded during an 18 month period were included. Data (demographic, preferences for place of death) were obtained from hospice records. Dying in preferred place was modelled using stepwise logistic regression analysis. Service use data (period between referral to hospice and death) were obtained from general practitioners, community providers, hospitals, social services, hospice, and costs calculated using validated national tariffs.

RESULTS

Of 688 patients referred to the hospice when the RRS was operational, 247 (35.9%) used it. Higher proportions of RRS users than non-users lived in their own homes with a co-resident carer (40.3% vs. 23.7%); more non-users lived alone or in residential care (58.8% vs. 76.3%). Chances of dying in the preferred place were enhanced 2.1 times by being a RRS user, compared to a non-user, and 1.5 times by having a co-resident carer, compared to living at home alone or in a care home. Total service costs did not differ between users and non-users, except when referred to hospice very close to death (users had higher costs).

CONCLUSIONS

Use of the RRS was associated with increased likelihood of dying in the preferred place. The RRS is cost neutral.

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 quasi-experimental controlled evaluation of the impact of a hospice rapid response community service for end-of-life care on achievement of preferred place of death

BACKGROUND

Rapid response services operating 24 h a day have been advocated in UK health policy to support dying patients at home, though there is limited evidence of their effectiveness.

AIM

To assess the impact of a rapid response hospice at home service (intervention) on people dying in their preferred place, and carer quality of life, compared to usual care (control).

DESIGN

Quasi-experimental multi-centred controlled evaluation. Patient data were collected from hospice records; carers completed postal questionnaires to report quality of life, anxiety and depression.

SETTING AND PARTICIPANTS

Community served by one hospice (three contiguous sites) in South East England; 953 patients who died with a preferred place of death recorded and 64 carers who completed questionnaires.

RESULTS

There was no significant difference between control and intervention groups in proportions achieving preferred place of death (61.9% vs 63.0% (odds ratio: 0.949; 95% confidence interval: 0.788-1.142)). People living at home alone were less likely to die where they wanted (0.541; 95% confidence interval: 0.438-0.667). Carers in the intervention group reported worse mental health component summary scores (short form-12, p = 0.03) than those in the control group; there were no differences in other carer outcomes.

CONCLUSION

The addition of a rapid response hospice at home service did not have a significant impact on helping patients to die where they wanted in an area already well served by community palliative care. Recording preferences, and changes over time, is difficult and presented challenges for this study.

Randomised controlled trial of the effectiveness of community group and home-based falls prevention exercise programmes on bone health in older people: the ProAct65+ bone study

BACKGROUND

exercise can reduce osteoporotic fracture risk by strengthening bone or reducing fall risk. Falls prevention exercise programmes can reduce fall incidence, and also include strengthening exercises suggested to load bone, but there is little information as to whether these programmes influence bone mineral density (BMD) and strength.

OBJECTIVE

to evaluate the skeletal effects of home (Otago Exercise Programme, OEP) and group (Falls Exercise Management, FaME) falls prevention exercise programmes relative to usual care in older people.

METHODS

men and women aged over 65 years were recruited through primary care. They were randomised by practice to OEP, FaME or usual care. BMD, bone mineral content (BMC) and structural properties were measured in Nottingham site participants before and after the 24-week intervention.

RESULTS

participants were 319 men and women, aged mean(SD) 72(5) years. Ninety-two percentage of participants completed the trial. The OEP group completed 58(43) min/week of home exercise, while the FaME group completed 39(16) and 30(24) min/week of group and home exercise, respectively. Femoral neck BMD changes did not differ between treatment arms: mean (95% CI) effect sizes in OEP and FaME relative to usual care arm were -0.003(-0.011,0.005) and -0.002(-0.010,0.005) g cm(-2), respectively; P = 0.44 and 0.53. There were no significant changes in BMD or BMC at other skeletal sites, or in structural parameters.

CONCLUSIONS

falls prevention exercise programmes did not influence BMD in older people. To increase bone strength, programmes may require exercise that exerts higher strains on bone or longer duration.

Multicentre cluster randomised trial comparing a community group exercise programme and home-based exercise with usual care for people aged 65 years and over in primary care

BACKGROUND

Regular physical activity (PA) reduces the risk of falls and hip fractures, and mortality from all causes. However, PA levels are low in the older population and previous intervention studies have demonstrated only modest, short-term improvements.

OBJECTIVE

To evaluate the impact of two exercise promotion programmes on PA in people aged ≥ 65 years.

DESIGN

The ProAct65+ study was a pragmatic, three-arm parallel design, cluster randomised controlled trial of class-based exercise [Falls Management Exercise (FaME) programme], home-based exercise [Otago Exercise Programme (OEP)] and usual care among older people (aged ≥ 65 years) in primary care.

SETTING

Forty-three UK-based general practices in London and Nottingham/Derby.

PARTICIPANTS

A total of 1256 people ≥ 65 years were recruited through their general practices to take part in the trial.

INTERVENTIONS

The FaME programme and OEP. FaME included weekly classes plus home exercises for 24 weeks and encouraged walking. OEP included home exercises supported by peer mentors (PMs) for 24 weeks, and encouraged walking.

MAIN OUTCOME MEASURES

The primary outcome was the proportion that reported reaching the recommended PA target of 150 minutes of moderate to vigorous physical activity (MVPA) per week, 12 months after cessation of the intervention. Secondary outcomes included functional assessments of balance and falls risk, the incidence of falls, fear of falling, quality of life, social networks and self-efficacy. An economic evaluation including participant and NHS costs was embedded in the clinical trial.

RESULTS

In total, 20,507 patients from 43 general practices were invited to participate. Expressions of interest were received from 2752 (13%) and 1256 (6%) consented to join the trial; 387 were allocated to the FaME arm, 411 to the OEP arm and 458 to usual care. Primary outcome data were available at 12 months after the end of the intervention period for 830 (66%) of the study participants. The proportions reporting at least 150 minutes of MVPA per week rose between baseline and 12 months after the intervention from 40% to 49% in the FaME arm, from 41% to 43% in the OEP arm and from 37.5% to 38.0% in the usual-care arm. A significantly higher proportion in the FaME arm than in the usual-care arm reported at least 150 minutes of MVPA per week at 12 months after the intervention [adjusted odds ratio (AOR) 1.78, 95% confidence interval (CI) 1.11 to 2.87; p = 0.02]. There was no significant difference in MVPA between OEP and usual care (AOR 1.17, 95% CI 0.72 to 1.92; p = 0.52). Participants in the FaME arm added around 15 minutes of MVPA per day to their baseline physical activity level. In the 12 months after the close of the intervention phase, there was a statistically significant reduction in falls rate in the FaME arm compared with the usual-care arm (incidence rate ratio 0.74, 95% CI 0.55 to 0.99; p = 0.042). Scores on the Physical Activity Scale for the Elderly showed a small but statistically significant benefit for FaME compared with usual care, as did perceptions of benefits from exercise. Balance confidence was significantly improved at 12 months post intervention in both arms compared with the usual-care arm. There were no statistically significant differences between intervention arms and the usual-care arm in other secondary outcomes, including quality-adjusted life-years. FaME is more expensive than OEP delivered with PMs (£269 vs. £88 per participant in London; £218 vs. £117 in Nottingham). The cost per extra person exercising at, or above, target was £1919.64 in London and £1560.21 in Nottingham (mean £1739.93).

CONCLUSION

The FaME intervention increased self-reported PA levels among community-dwelling older adults 12 months after the intervention, and significantly reduced falls. Both the FaME and OEP interventions appeared to be safe, with no significant differences in adverse reactions between study arms.

A trial of devices for urinary incontinence after treatment for prostate cancer

OBJECTIVE

To compare the performance of three continence management devices and absorbent pads used by men with persistent urinary incontinence (>1 year) after treatment for prostate cancer.

PATIENTS AND METHODS

Randomised, controlled trial of 56 men with 1-year follow-up. Three devices were tested for 3 weeks each: sheath drainage system, body-worn urinal (BWU) and penile clamp. Device and pad performance were assessed. Quality of life (QoL) was measured at baseline and follow-up with the King's Health Questionnaire. Stated (intended use) and revealed (actual use) preference for products were assessed. Value-for-money was gathered.

RESULTS

Substantial and significant differences in performance were found. The sheath was rated as 'good' for extended use (e.g. golf and travel) when pad changing is difficult; for keeping skin dry, not leaking, not smelling and convenient for storage and travel. The BWU was generally rated worse than the sheath and was mainly used for similar activities but by men who could not use a sheath (e.g. retracted penis) and was not good for seated activities. The clamp was good for short vigorous activities like swimming/exercise; it was the most secure, least likely to leak, most discreet but almost all men described it as uncomfortable or painful. The pads were good for everyday activities and best for night-time use; most easy to use, comfortable when dry but most likely to leak and most uncomfortable when wet. There was a preference for having a mixture of products to meet daytime needs; around two-thirds of men were using a combination of pads and devices after testing compared with baseline.

CONCLUSIONS

This is the first trial to systematically compare different continence management devices for men. Pads and devices have different strengths, which make them particularly suited to certain circumstances and activities. Most men prefer to use pads at night but would choose a mixture of pads and devices during the day. Device limitations were important but may be overcome by better design.

Service utilisation and family support of people with dementia: a cohort study in England

OBJECTIVES

This study aimed to compare costs of caring for people with dementia in domiciliary and residential settings, central England.

METHODS

A cohort of people with dementia was recruited during a hospital stay 2008-2010. Data were collected by interview at baseline, and 6- and 12-month follow-up, covering living situation (own home with or without co-resident carer, care home); cognition, health status and functioning of person with dementia; carer stress; utilisation of health and social services; and informal (unpaid) caring input. Costs of formal services and informal caring (replacement cost method) were calculated. Costs of residential and domiciliary care packages were compared.

RESULTS

Data for 109 people with dementia were collected at baseline; 95 (87.2%) entered hospital from their own homes. By 12 months, 40 (36.7%) had died and 85% of the survivors were living in care homes. Over one-half of people with dementia reported social care packages at baseline; those living alone had larger packages than those living with others. Median caring time for co-resident carers was 400 min/day and 10 h/week for non co-resident carers. Residential care was more costly than domiciliary social care for most people. When the value of informal caring was included, the total cost of domiciliary care was higher than residential care, but not significantly so. Carer stress reduced significantly after the person with dementia entered a care home.

CONCLUSIONS

Caring for people with dementia at home may be more expensive, and more stressful for carers, than care in residential settings.

Specialist rehabilitation for people with Parkinson’s disease in the community: a randomised controlled trial

Background

Multidisciplinary rehabilitation is recommended for Parkinson’s disease, but evidence suggests that benefit is not sustained.

Objectives

(1) Implement a specialist domiciliary rehabilitation service for people with Parkinson’s and carers. (2) Provide continuing support from trained care assistants to half receiving the rehabilitation. (3) Evaluate the clinical effectiveness of the service, and the value added by the care assistants, compared with usual care. (4) Assess the costs of the interventions. (5) Investigate the acceptability of the service. (6) Deliver guidance for commissioners.

Design

Pragmatic three-parallel group randomised controlled trial.

Setting

Community, county of Surrey, England, 2010–11.

Participants

People with Parkinson’s, at all stages of the disease, and live-in carers.

Interventions

Groups A and B received specialist rehabilitation from a multidisciplinary team (MDT) – comprising Parkinson’s nurse specialists, physiotherapists, occupational therapists, and speech and language therapists – delivered at home, tailored to individual needs, over 6 weeks (about 9 hours’ individual therapy per patient). In addition to the MDT, participants in group B received ongoing support for a further 4 months from a care assistant trained in Parkinson’s (PCA), embedded in the MDT (1 hour per week per patient). Participants in control group (C) received care as usual (no co-ordinated MDT or ongoing support).

Main outcome measures

Follow-up assessments were conducted in participants’ homes at 6, 24 and 36 weeks after baseline. Primary outcomes: Self-Assessment Parkinson’s Disease Disability Scale (patients); the Modified Caregiver Strain Index (carers). Secondary outcomes included: for patients, disease-specific and generic health-related quality of life, psychological well-being, self-efficacy, mobility, falls and speech; for carers, strain, stress, health-related quality of life, psychological well-being and functioning.

Results

A total of 306 people with Parkinson’s (and 182 live-in carers) were randomised [group A,n = 102 (n = 61); group B,n = 101 (n = 60); group C,n = 103 (n = 61)], of whom 269 (155) were analysed at baseline, pilot cohort excluded. Attrition occurred at all stages. A per-protocol analysis [people with Parkinson’s,n = 227 (live-in carers,n = 125)] [group A,n = 75 (n = 45); group B,n = 69 (n = 37); group C,n = 83 (n = 43)] showed that, at the end of the MDT intervention, people with Parkinson’s in groups A and B, compared with group C, had reduced anxiety (p = 0.02); their carers had improved psychological well-being (p = 0.02). People with Parkinson’s in groups A and B also had marginally reduced disability (primary outcome,p = 0.09), and improved non-motor symptoms (p = 0.06) and health-related quality of life (p = 0.07), compared with C. There were significant differences in change scores between week 6 (end of MDT) and week 24 (end of PCA for group B) in favour of group B, owing to worsening in group A (no PCA support) in posture (p = 0.001); non-motor symptoms (p = 0.05); health-related quality of life (p = 0.07); and self-efficacy (p = 0.09). Carers in group B (vs. group A) reported a tendency for reduced strain (p = 0.06). At 36 weeks post recruitment, 3 months after the end of PCA support for group B, there were few differences between the groups. Participants reported learning about Parkinson’s, and valued individual attention. The MDT cost £833; PCA support was £600 extra, per patient (2011 Great British pounds).

Conclusions

Further research is needed into ways of sustaining benefits from rehabilitation including the use of care assistants.

Exercise for reducing fear of falling in older people living in the community

BACKGROUND

Fear of falling is common in older people and associated with serious physical and psychosocial consequences. Exercise (planned, structured, repetitive and purposive physical activity aimed at improving physical fitness) may reduce fear of falling by improving strength, gait, balance and mood, and reducing the occurrence of falls.

OBJECTIVES

To assess the effects (benefits, harms and costs) of exercise interventions for reducing fear of falling in older people living in the community.

SEARCH METHODS

We searched the Cochrane Bone, Joint and Muscle Trauma Group Specialised Register (July 2013), the Central Register of Controlled Trials (CENTRAL 2013, Issue 7), MEDLINE (1946 to July Week 3 2013), EMBASE (1980 to 2013 Week 30), CINAHL (1982 to July 2013), PsycINFO (1967 to August 2013), AMED (1985 to August 2013), the World Health Organization International Clinical Trials Registry Platform (accessed 7 August 2013) and Current Controlled Trials (accessed 7 August 2013). We applied no language restrictions. We handsearched reference lists and consulted experts.

SELECTION CRITERIA

We included randomised and quasi-randomised trials that recruited community-dwelling people (where the majority were aged 65 and over) and were not restricted to specific medical conditions (e.g. stroke, hip fracture). We included trials that evaluated exercise interventions compared with no intervention or a non-exercise intervention (e.g. social visits), and that measured fear of falling. Exercise interventions were varied; for example, they could be 'prescriptions' or recommendations, group-based or individual, supervised or unsupervised.

DATA COLLECTION AND ANALYSIS

Pairs of review authors independently assessed studies for inclusion, assessed the risk of bias in the studies and extracted data. We combined effect sizes across studies using the fixed-effect model, with the random-effect model used where significant statistical heterogeneity was present. We estimated risk ratios (RR) for dichotomous outcomes and incidence rate ratios (IRR) for rate outcomes. We estimated mean differences (MD) where studies used the same continuous measures and standardised mean differences (SMD) where different measures or different formats of the same measure were used. Where possible, we performed various, usually prespecified, sensitivity and subgroup analyses.

MAIN RESULTS

We included 30 studies, which evaluated 3D exercise (Tai Chi and yoga), balance training or strength and resistance training. Two of these were cluster-randomised trials, two were cross-over trials and one was quasi-randomised. The studies included a total of 2878 participants with a mean age ranging from 68 to 85 years. Most studies included more women than men, with four studies recruiting women only. Twelve studies recruited participants at increased risk of falls; three of these recruited participants who also had fear of falling.Poor reporting of the allocation methods in the trials made it difficult to assess the risk of selection bias in most studies. All of the studies were at high risk of performance and detection biases as there was no blinding of participants and outcome assessors and the outcomes were self reported. Twelve studies were at high risk of attrition bias. Using GRADE criteria, we judged the quality of evidence to be 'low' for fear of falling immediately post intervention and 'very low' for fear of falling at short or long-term follow-up and all other outcomes.Exercise interventions were associated with a small to moderate reduction in fear of falling immediately post intervention (SMD 0.37 favouring exercise, 95% confidence interval (CI) 0.18 to 0.56; 24 studies; 1692 participants, low quality evidence). Pooled effect sizes did not differ significantly between the different scales used to measure fear of falling. Although none of the sensitivity analyses changed the direction of effect, the greatest reduction in the size of the effect was on removal of an extreme outlier study with 73 participants (SMD 0.24 favouring exercise, 95% CI 0.12 to 0.36). None of our subgroup analyses provided robust evidence of differences in effect in terms of either the study primary aim (reduction of fear of falling or other aim), the study population (recruitment on the basis of increased falls risk or not), the characteristics of the study exercise intervention or the study control intervention (no treatment or alternative intervention). However, there was some weak evidence of a smaller effect, which included no reduction, of exercise when compared with an alternative control.There was very low quality evidence that exercise interventions may be associated with a small reduction in fear of falling up to six months post intervention (SMD 0.17, 95% CI -0.05 to 0.38; four studies, 356 participants) and more than six months post intervention (SMD 0.20, 95% CI -0.01 to 0.41; three studies, 386 participants).Very low quality evidence suggests exercise interventions in these studies that also reported on fear of falling reduced the risk of falling measured either as participants incurring at least one fall during follow-up or the number of falls during follow-up. Very low quality evidence from four studies indicated that exercise interventions did not appear to reduce symptoms of depression or increase physical activity. The only study reporting the effects of exercise interventions on anxiety found no difference between groups. No studies reported the effects of exercise interventions on activity avoidance or costs. It is important to remember that our included studies do not represent the totality of the evidence of the effect of exercise interventions on falls, depression, anxiety or physical activity as our review only includes studies that reported fear of falling.

AUTHORS' CONCLUSIONS

Exercise interventions in community-dwelling older people probably reduce fear of falling to a limited extent immediately after the intervention, without increasing the risk or frequency of falls. There is insufficient evidence to determine whether exercise interventions reduce fear of falling beyond the end of the intervention or their effect on other outcomes. Although further evidence from well-designed randomised trials is required, priority should be given to establishing a core set of outcomes that includes fear of falling for all trials examining the effects of exercise interventions in older people living in the community.

Comparison of sole nurse and team-delivered community clozapine services for people with treatment-resistant schizophrenia

AIM

To compare sole nurse and doctor-led multidisciplinary team delivery of community clozapine services for people with treatment-resistant schizophrenia.

BACKGROUND

Around 20% of people with schizophrenia are treatment resistant and fail to respond to front line medications. Clozapine, a second-line treatment, has potentially serious side effects requiring regular monitoring. Different models of community clozapine services are emerging in the British National Health Service, but there is little evidence about which is best.

DESIGN

Questionnaire survey of service users.

METHODS

All patients on the lists of seven clozapine clinics (four sole nurse, three multidisciplinary team) in one trust were invited to participate, 2009-2010. Forward stepwise regression was used to investigate associations between patient well-being, functioning, self-efficacy and satisfaction, and clinic model attended, controlling for socio-demographic and health characteristics and processes of care. Use (and costs) of other health and social services accessed was compared between models.

RESULTS

Sixty-six service users (35% participation rate) responded. Well-being and functioning were associated with patient characteristics and processes of care, not clinic model. Patients managed by sole nurses reported, over 3 months: more community psychiatric nurse visits and hospital psychiatrist appointments. Clinic list size affects costs per patient.

CONCLUSIONS

Multidisciplinary team delivery may reduce use of other services. Although multidisciplinary team delivery is regarded as best practice, sole nurses can effectively provide clozapine services and may be warranted in areas of low population density.

Laparoscopic versus open colorectal resection for cancer and polyps: a cost-effectiveness study

Background

Available evidence that compares outcomes from laparoscopic and open surgery for colorectal cancer shows no difference in disease free or survival time, or in health-related quality of life outcomes, but does not capture the short term benefits of laparoscopic methods in the early postoperative period.

Aim

To explore the cost-effectiveness of laparoscopic colorectal surgery, compared to open methods, using quality of life data gathered in the first 6 weeks after surgery.

Methods

Participants were recruited in 2006–2007 in a district general hospital in the south of England; those with a diagnosis of cancer or polyps were included in the analysis. Quality of life data were collected using EQ-5D, on alternate days after surgery for 4 weeks. Costs per patient, from a National Health Service perspective (in British pounds, 2006) comprised the sum of operative, hospital, and community costs. Missing data were filled using multiple imputation methods. The difference in mean quality adjusted life years and costs between surgery groups were estimated simultaneously using a multivariate regression model applied to 20 imputed datasets. The probability that laparoscopic surgery is cost-effective compared to open surgery for a given societal willingness-to-pay threshold is illustrated using a cost-effectiveness acceptability curve.

Results

The sample comprised 68 laparoscopic and 27 open surgery patients. At 28 days, the incremental cost per quality adjusted life year gained from laparoscopic surgery was £12,375. At a societal willingness-to-pay of £30,000, the probability that laparoscopic surgery is cost-effective, exceeds 65% (at £20,000 ≈60%). In sensitivity analyses, laparoscopic surgery remained cost-effective compared to open surgery, provided it results in a saving ≥£699 in hospital bed days and takes no more than 8 minutes longer to perform.

Conclusion

The study provides formal evidence of the cost-effectiveness of laparoscopic approaches and supports current guidelines that promote use of laparoscopy where suitably trained surgeons are available.

Effective health care for older people resident in care homes: the optimal study protocol for realist review

BACKGROUND

Care homes in the UK rely on general practice for access to specialist medical and nursing care as well as referral to therapists and secondary care. Service delivery to care homes is highly variable in both quantity and quality. This variability is also evident in the commissioning and organisation of care home-specific services that range from the payment of incentives to general practitioners (GPs) to visit care homes, to the creation of care home specialist teams and outreach services run by geriatricians. No primary studies or systematic reviews have robustly evaluated the impact of these different approaches on organisation and resident-level outcomes. Our aim is to identify factors which may explain the perceived or demonstrated effectiveness of programmes to improve health-related outcomes in older people living in care homes.

METHODS/DESIGN

A realist review approach will be used to develop a theoretical understanding of what works when, why and in what circumstances. Elements of service models of interest include those that focus on assessment and management of residents' health, those that use strategies to encourage closer working between visiting health care providers and care home staff, and those that address system-wide issues about access to assessment and treatment. These will include studies on continence, dignity, and speech and language assessment as well as interventions to promote person centred dementia care, improve strength and mobility, and nutrition. The impact of these interventions and their different mechanisms will be considered in relation to five key outcomes: residents' medication use, use of out of hours' services, hospital admissions (including use of Accident and Emergency) and length of hospital stay, costs and user satisfaction. An iterative three-stage approach will be undertaken that is stakeholder-driven and optimises the knowledge and networks of the research team.

DISCUSSION

This realist review will explore why and for whom different approaches to providing health care to residents in care homes improves access to health care in the five areas of interest. It will inform commissioning decisions and be the basis for further research. This systematic review protocol is registered on the PROSPERO database reference number: CRD42014009112.

Investigating the contribution of physician assistants to primary care in England: a mixed-methods study

Background

Primary health care is changing as it responds to demographic shifts, technological changes and fiscal constraints. This, and predicted pressures on medical and nursing workforces, raises questions about staffing configurations. Physician assistants (PAs) are mid-level practitioners, trained in a medical model over 2 years at postgraduate level to work under a supervising doctor. A small number of general practices in England have employed PAs.

Objective

To investigate the contribution of PAs to the delivery of patient care in primary care services in England.

Design

A mixed-methods study conducted at macro, meso and micro organisational levels in two phases: (1) a rapid review, a scoping survey of key national and regional informants, a policy review, and a survey of PAs and (2) comparative case studies in 12 general practices (six employing PAs). The latter incorporated clinical record reviews, a patient satisfaction survey, video observations of consultations and interviews with patients and professionals.

Results

The rapid review found 49 published studies, mainly from the USA, which showed increased numbers of PAs in general practice settings but weak evidence for impact on processes and patient outcomes. The scoping survey found mainly positive or neutral views about PAs, but there was no mention of their role in workforce policy and planning documents. The survey of PAs in primary care (n = 16) found that they were mainly deployed to provide same-day appointments. The comparative case studies found that physician assistants were consulted by a wide range of patients, but these patients tended to be younger, with less medically acute or complex problems than those consulting general practitioners (GPs). Patients reported high levels of satisfaction with both PAs and GPs. The majority were willing or very willing to consult a PA again but wanted choice in which type of professional they consulted. There was no significant difference between PAs and GPs in the primary outcome of patient reconsultation for the same problem within 2 weeks, investigations/tests ordered, referrals to secondary care or prescriptions issued. GPs, blinded to the type of clinician, judged the documented activities in the initial consultation of patients who reconsulted for the same problem to be appropriate in 80% (n = 223) PA and 50% (n = 252) GP records. PAs were judged to be competent and safe from observed consultations. The average consultation with a physician assistant is significantly longer than that with a GP: 5.8 minutes for patients of average age for this sample (38 years). Costs per consultation were £34.36 for GPs and £28.14 for PAs. Costs could not be apportioned to GPs for interruptions, supervision or training of PAs.

Conclusions

PAs were found to be acceptable, effective and efficient in complementing the work of GPs. PAs can provide a flexible addition to the primary care workforce. They offer another labour pool to consider in health professional workforce and education planning at local, regional and national levels. However, in order to maximise the contribution of PAs in primary care settings, consideration needs to be given to the appropriate level of regulation and the potential for authority to prescribe medicines. Future research is required to investigate the contribution of PAs to other first contact services as well as secondary services; the contribution and impact of all types of mid-level practitioners (including nurse practitioners) in first contact services; the factors and influences on general practitioner and practice manager decision-making as to staffing and skill mix; and the reliability and validity of classification systems for both primary care patients and their presenting condition and their consequences for health resource utilisation.

The value of diastolic function parameters in the prediction of left atrial appendage thrombus in patients with nonvalvular atrial fibrillation

BACKGROUND

Left ventricular diastolic impairment and consequently elevated filling pressure may contribute to stasis leading to left atrial appendage thrombus (LAAT) in nonvalvular atrial fibrillation (AF). We investigated whether transthoracic echocardiographic parameters can predict LAAT independent of traditional clinical predictors.

METHODS

We conducted a retrospective cohort study of 297 consecutive nonvalvular AF patients who underwent transthoracic echocardiogram followed by a transesophageal echocardiogram within one year. Multivariate logistic regression analysis models were used to determine factors independently associated with LAAT.

RESULTS

Nineteen subjects (6.4%) were demonstrated to have LAAT by transesophageal echocardiography. These patients had higher mean CHADS2 scores [2.6 ± 1.2 vs. 1.9 ± 1.3, P = 0.009], higher E:e' ratios [16.6 ± 6.1 vs. 12.0 ± 5.4, P = 0.001], and lower mean e' velocities [6.5 ± 2.1 cm/sec vs. 9.1 ± 3.2 cm/sec, P = 0.001]. Both E:e' and e' velocity were associated with LAAT formation independent of the CHADS2 score, warfarin therapy, left ventricular ejection fraction (LVEF), and left atrial volume index (LAVI) [E:e' odds-ratio = 1.14 (95% confidence interval = 1.03 - 1.3), P = 0.009; e' velocity odds-ratio = 0.68 (95% confidence interval = 0.5 - 0.9), P = 0.007]. Similarly, diastolic function parameters were independently associated with spontaneous echo contrast.

CONCLUSION

The diastolic function indices E:e' and e' velocity are independently associated with LAAT in nonvalvular AF patients and may help identify patients at risk for LAAT.
