Development, implementation and evaluation of a new nurse-led continence service: a pilot study.

The Leicestershire Medical Research Council (MRC) Incontinence Study is a series of interrelated studies exploring the epidemiology of urinary symptoms, including incontinence, and evaluating service provision and treatment options for these symptoms. This paper describes one aspect of the Leicestershire MRC Incontinence Study, namely the development, implementation and evaluation of a new nurse-led continence service. When developing a new service it is important to determine its acceptability and suitability to the target population. The new mode of service delivery was dependent on specially trained Continence Nurse Practitioners (CNP) delivering predefined evidence-based treatment interventions. Objective and subjective outcome measures were used to evaluate the service. The service was shown to be effective in reducing urinary symptoms and led to high levels of patient satisfaction. This service is currently being evaluated in a randomized controlled trial.

An epidemiological study to establish the prevalence of urinary symptoms and felt need in the community: the Leicestershire MRC Incontinence Study. Leicestershire MRC Incontinence Study Team.

BACKGROUND: The aim of the study was to establish the prevalence of urinary symptoms and felt need in adults. This paper discusses problems with setting thresholds to distinguish cases from non-cases in this field of research. Few studies have provided detailed age- and sex-specific prevalence estimates for felt need in relation to urinary symptoms. METHODS: A cross-sectional postal survey was carried out of 15,904 community-dwelling adults aged 40 years or more registered with general practitioners in Leicestershire. Subjects were selected randomly by household from the Leicestershire Health Authority Register. The postal questionnaire consisted of questions on general health, urinary and bowel symptoms, quality of life, service use and demographic characteristics. RESULTS: Thirty-four per cent of the sample reported clinically significant symptoms. The prevalence and severity of symptoms increased with age. However, only 2 per cent of the sample reported symptoms that were clinically significant, bothersome and socially disabling. CONCLUSION: Urinary symptoms are very common in adults over 40 years of age living in the community. However, symptom-based estimates probably overestimate the level of need for health care in the community. It may be more effective and efficient to target services, in the first instance, on those people who report clinically significant symptoms that are bothersome or socially disabling. A consensus on thresholds and definitions of urinary symptoms is required to standardize clinical and research work and to target services more appropriately.

Determinants of raised C-reactive protein concentration in type 1 diabetes.

As a marker of systemic inflammation, raised C-reactive protein (CRP) concentrations which are still within the normal range have been associated with an increased incidence of coronary heart disease (CHD) in non-diabetic subjects. This study aimed to establish potential determinants of raised CRP concentrations in type 1 diabetic patients. We used a sensitive assay to measure 'low-level' CRP concentrations in 167 type 1 patients (93M, 74F, median age 30 years, range 13-67). Stepwise multivariate analysis was used to relate these CRP levels to known cardiovascular risk factors and demographic data. Only six patients had established CHD (median CRP 3.34 mg/l vs. 0.83 mg/l, p=0.032). In subjects without overt CHD, multivariate analysis showed increases in subject age (p=0.0025), BMI (p=0.001) and HbA(1) (p=0.012) to be associated with a higher CRP concentration, as was female sex (p=0.026) and a history of CHD in a first-degree relative (p=0.018, n=57). The duration of diabetes, current smoking status, presence of microvascular complications, lipid status and presence of hypertension were unrelated. This study suggests that some of the risk factors associated with CHD in type 1 patients are also independently predictive of high CRP concentrations. The reasons for this, and whether intervention would prove useful, require further investigation.

Prevalence and impact of urinary symptoms among community-dwelling stroke survivors.

BACKGROUND AND PURPOSE: To establish prevalence of urinary symptoms among community-dwelling stroke survivors and how these symptoms affected lives of these survivors compared with a nonstroke population. METHODS: The present study was a community-based postal survey in Leicestershire community, UK (that excluded institutional settings), that was designed to track stroke, urinary, and bowel symptoms and the effect of such symptoms on relationships, social life, daily activities, and overall quality of life. Subjects included 14 600 people who were living in the community and </=40 years of age, randomly selected from the Leicestershire Health Authority Register. RESULTS: A 70% response rate was achieved with the return of 10 226 questionnaires. Prevalence of reported stroke was 4% (n=423). Prevalence of urinary symptoms was 34% (n=3197). Overall, stroke survivors had a higher prevalence of symptoms than the nonstroke population (64% to 32%, respectively). These symptoms were reported to have more of an effect on the lives of the stroke survivors compared with the nonstroke population even when adjusted for age and sex differences. This reported impact was not related to the stroke per se but to the severity of the urinary symptoms. CONCLUSIONS: These data show a high prevalence of urinary symptoms among community-dwelling stroke survivors. These symptoms were reported to have considerable impact on the lives of stroke survivors, which needs to be taken into account in future research and clinical practice.

Best place of care for older people after acute and during subacute illness: a systematic review.

OBJECTIVES: To assess the evaluative research literature on the costs, quality and effectiveness of different locations of care for older patients. METHODS: A systematic review of evaluative research from 1988 using CRD4 guidelines. Twenty-five databases were searched, using processes developed specially for this review. Library OPACS, the Internet and research registers were also searched for relevant material. The final stage of the review was confined to randomised and pseudorandomised trials. Studies were selected for review by pairs of researchers working independently who then met to reach a decision. Analysis was predominantly descriptive; simple pooled odds ratios were used to explore some outcomes. RESULTS: Eighty-four papers from 45 trials were included. Firm conclusions were difficult to draw, except in relation to some outcomes for stroke units, early discharge schemes and geriatric assessment units. Few trials in this area have adequately addressed issues of patients' quality of life and costs to health services, social care providers, patients and their families. CONCLUSIONS: Despite considerable recent development of different forms of care for older patients, evidence about effectiveness and costs is weak. However, evidence is also weak for longer-standing care models. A substantial service evaluation agenda emerges from this review. This study also raises questions about the usefulness of systematic review techniques in the area of service delivery and organisation.

Prevalence of dementia and major subtypes in Europe: A collaborative study of population-based cohorts. Neurologic Diseases in the Elderly Research Group.

The last comparison of prevalence figures of dementia across European studies was 10 years ago. Using studies conducted in the 1990s, the authors compare the age- and sex-specific prevalence of dementia, AD, and vascular dementia (VaD) across European population-based studies of persons 65 years and older. Data from these studies were also pooled to obtain stable estimates of age- and sex-specific prevalence. A total of 2346 cases of mild to severe dementia were identified in 11 cohorts. Age-standardized prevalence was 6.4% for dementia (all causes), 4.4% for AD, and 1.6% for VaD. The prevalence of dementia increased continuously with age and was 0.8% in the group age 65 to 69 years and 28.5% at age 90 years and older. The corresponding figures for AD (53.7% of cases) were 0.6% and 22.2%, and for VaD (15.8% of cases), 0.3% and 5.2%. Variation of AD prevalence across studies was greatest for men. In the VaD subtype, a large variation across studies was observed, as well as a difference in prevalence between men and women that was age dependent. Dementia is more prevalent in women, and AD is the main contributor to the steep increase of prevalence with age.

Prognosis with dementia in Europe: A collaborative study of population-based cohorts. Neurologic Diseases in the Elderly Research Group.

The effect of dementia on time to death and institutionalization in elderly populations is of importance to resource planning, as well as to patients and their carers. The authors report a collaborative reanalysis of nine population-based studies conducted in Europe to compare dementia cases and noncases in risk of and time to death and to institutionalization. Prevalent and incident cases were more likely than noncases to reside in an institution at baseline and were more likely to enter institutional care. Prevalent cases also had over twice the risk of death compared to noncases and survival for men with dementia was consistently lower than that for women with dementia of the same age group.

Randomised controlled trial of effectiveness of Leicester hospital at home scheme compared with hospital care.

OBJECTIVE: To compare effectiveness of patient care in hospital at home scheme with hospital care. DESIGN: Pragmatic randomised controlled trial. SETTING: Leicester hospital at home scheme and the city's three acute hospitals. PARTICIPANTS: 199 consecutive patients referred to hospital at home by their general practitioner and assessed as being suitable for admission. Six of 102 patients randomised to hospital at home refused admission, as did 23 of 97 allocated to hospital. INTERVENTION: Hospital at home or hospital inpatient care. MAIN OUTCOME MEASURES: Mortality and change in health status (Barthel index, sickness impact profile 68, EuroQol, Philadelphia geriatric morale scale) assessed at 2 weeks and 3 months after randomisation. The main process measures were service inputs, discharge destination, readmission rates, length of initial stay, and total days of care. RESULTS: Hospital at home group and hospital group showed no significant differences in health status (median scores on sickness impact profile 68 were 29 and 30 respectively at 2 weeks, and 24 and 26 at 3 months) or in dependency (Barthel scores 15 and 14 at 2 weeks and 16 for both groups at 3 months). At 3 months' follow up, 26 (25%) of hospital at home group had died compared with 30 (31%) of hospital group (relative risk 0. 82 (95% confidence interval 0.52 to 1.28)). Hospital at home group required fewer days of treatment than hospital group, both in terms of initial stay (median 8 days v 14.5 days, P=0.026) and total days of care at 3 months (median 9 days v 16 days, P=0.031). CONCLUSIONS: Hospital at home scheme delivered care as effectively as hospital, with no clinically important differences in health status. Hospital at home resulted in significantly shorter lengths of stay, which did not lead to a higher rate of subsequent admission.

Economic evaluation of hospital at home versus hospital care: cost minimisation analysis of data from randomised controlled trial.

OBJECTIVES: To compare the costs of admission to a hospital at home scheme with those of acute hospital admission. DESIGN: Cost minimisation analysis within a pragmatic randomised controlled trial. SETTING: Hospital at home scheme in Leicester and the city's three acute hospitals. PARTICIPANTS: 199 consecutive patients assessed as being suitable for admission to hospital at home for acute care during the 18 month trial period (median age 84 years). INTERVENTION: Hospital at home or hospital inpatient care. MAIN OUTCOME MEASURES: Costs to NHS, social services, patients, and families during the initial episode of treatment and the three months after admission. RESULTS: Mean (median) costs per episode (including any transfer from hospital at home to hospital) were similar when analysed by intention to treat-hospital at home 2569 pounds sterling (1655 pounds sterling), hospital ward 2881 pounds sterling (2031 pounds sterling), bootstrap mean difference -305 (95% confidence interval -1112 to 448). When analysis was restricted to those who accepted their allocated place of care, hospital at home was significantly cheaper-hospital at home 2557 pounds sterling(1710 pounds sterling), hospital ward 3660 pounds sterling (2903 pounds sterling), bootstrap mean difference -1071 (-1843 to -246). At three months the cost differences were sustained. Costs with all cases included were hospital at home 3671 pounds sterling (2491 pounds sterling), hospital ward 3877 pounds sterling (3405 pounds sterling), bootstrap mean difference -210 (-1025 to 635). When only those accepting allocated care were included the costs were hospital at home 3698 pounds sterling (2493 pounds sterling), hospital ward 4761 pounds sterling (3940 pounds sterling), bootstrap mean difference -1063 (-2044 to -163); P=0.009. About 25% of the costs for episodes of hospital at home were incurred through transfer to hospital. Costs per day of care were higher in the hospital at home arm (mean 207 pounds sterling v 134 pounds sterling in the hospital arm, excluding refusers, P<0.001). CONCLUSIONS: Hospital at home can deliver care at similar or lower cost than an equivalent admission to an acute hospital.

Factors associated with vascular dementia in an elderly community population.

OBJECTIVE: Examination of associated factors for vascular dementia in comparison with Alzheimer's disease and a non-demented control population. SETTING: A semi-rural geographically defined population, in Melton Mowbray and the surrounding area, consisting of elderly patients aged 75 and over from a 13-doctor general practice. METHOD: 438 subjects, sampled according to results of initial screening with the Mini-Mental State Examination (MMSE), were examined using the Cambridge Mental Disorders of the Elderly Examination (CAMDEX), which was also used to classify the subtypes of dementia. RESULTS: 34 subjects had vascular dementia, 222 had Alzheimer's disease and 140 were non-demented according to the clinician's diagnosis based on the CAMDEX criteria. Significant factors associated with vascular dementia, when compared to the Alzheimer's disease and non-demented groups, were family history of stroke and diabetes. Stroke was also significant, but this factor is one of those defining the criteria for diagnostic grouping. There were no significant differences between groups for falls, heart attack, hypertension, head injury, substance abuse or lipid levels. CONCLUSION: The results are broadly consistent with the published literature and emphasize the importance of diabetes as a key risk factor for vascular dementia.

The porcine calcitonin receptor promoter directs expression of a linked reporter gene in a tissue and developmental specific manner in transgenic mice.

We have investigated the transcriptional regulation of the porcine calcitonin (CT) receptor (pCTR) promoter in transgenic mice. A construct containing 2.1 kb pCTR 5' flanking region, fused to a beta-galactosidase (lacZ) gene, was employed for the production of transgenic mice. At 11.5 days of development lacZ expression was observed in the embryonic brain and spinal cord. By 15.5 days post fertilization, lacZ expression was detected in the developing mammary gland, external ear, cartilage primordium of the humerus, and anterior naris (nostril). RT-PCR on RNA from these fetal tissues showed endogenous mouse CTR (mCTR) expression. In neonatal and adult transgenics, lacZ expression was silenced, except in brain, spinal cord, and testis (adults only). Endogenous mCTR gene expression and pCTR promoter activity were corepressed in the same tissues from adult mice. No pCTR promoter activity was detected in the kidney or bone of transgenic animals. This suggests that additional DNA sequences may be required for pCTR promoter activity in these tissues. From these results, we conclude that the pCTR promoter is active only in tissues expressing endogenous mCTR. Many of the these tissues represent previously unknown sites of CTR gene expression. Finally, the developmental regulation of pCTR/mCTR in tissues such as breast and cartilage primordium suggests that CTRs may play a role in the morphogenesis of these tissues.

Using an annual over-75 health check to screen for depression: validation of the short Geriatric Depression Scale (GDS15) within general practice.

OBJECTIVE: To validate the short Geriatric Depression Scale (GDS15) as a screening instrument and determine the optimal cutpoint for detecting depression among older people living in the community. DESIGN: Two stage study with the first stage consisting of a health check of people aged 75 years and over by a practice nurse which included the GDS15. A second-stage diagnostic interview including the criterion standard was carried out blind to GDS15 score. SETTING: A large general practice in Melton Mowbray, Leicestershire, UK. PATIENTS: A random sample (stratified according to first-stage GDS15 score) of 257 older people living in the community, without significant cognitive impairment, were selected for the second-stage diagnostic interview. MEASURES: The first-stage GDS15 score was compared with diagnostic status for depression and anxiety disorders (according to ICD-10 criteria) and presence of depressive symptoms at the second-stage clinical interview. RESULTS: Ninety-three per cent of those eligible for the study were successfully screened with the GDS15. A cutpoint of <3/3+ had a sensitivity of 100% and specificity of 72% in detecting cases of depression but fewer than one in five of those testing positive reached a diagnostic threshold. Only 25% of those with a diagnosis of depression had any mention of mental health problems in their medical notes in the year prior to the clinical interview. For detecting depressive symptoms the same cutpoint was 79% sensitive and 78% specific with a positive predictive value of 46%. CONCLUSIONS: Used as part of an annual over-75 health check in primary care, the GDS15 would detect a significant amount of hidden morbidity which would serve the original purpose of the annual elderly health checks in the UK.

Is the diagnosis of dementia stable over time among elderly immigrant Gujaratis in the United Kingdom (Leicester)?

BACKGROUND: The single largest ethnic elder group in the United Kingdom originates from the Indian subcontinent and their numbers are increasing. METHOD: Elderly Gujarati subjects, with a diagnosis of dementia ascertained during an epidemiological field study in Leicester, were reexamined at a median follow-up interval of 27 months to establish stability of the original diagnosis and cognitive decline. RESULTS: Seven of the original 11 subjects with dementia were alive at the follow-up and they were reexamined by a Gujarati psychiatrist. In six of these seven subjects the diagnosis of dementia was reconfirmed with concomitant cognitive decline on the CAMDEX dementia severity index. Informant history in three of the four original dementia subjects provided evidence of cognitive decline between the original interview and death. CONCLUSION: The diagnosis of dementia in elderly Gujaratis was stable at follow-up with concurrent evidence of decline. This also provided further support for the validity and performance of the Gujarati MMSE in the original study.

Measuring health status in older patients. The SF-36 in practice.

OBJECTIVE: To examine the use of the Medical Outcomes Study short form 36-item (SF-36) health status measure in older patients receiving health care; to explore the influence of age and physical and cognitive status on response to and completion of the SF-36 questionnaire. DESIGN: Prospective observational study. SETTINGS: Hospital and ambulatory patients aged 65 years and over in the medical and surgical wards and outpatient department of a teaching hospital and a local general practitioner's surgery. SUBJECTS: 1014 hospital inpatients, 80 hospital outpatients and 40 patients attending their general practitioner's surgery. MAIN OUTCOME MEASURES: Response rates, overall rates of completion (sufficient to calculate a valid SF-36 score) and completion of individual questions. RESULTS: 37 out of 40 ambulatory patients in general practice (93%) and 71 out of 80 outpatients (89%) returned a self-completed questionnaire. In hospital inpatients the overall response rate was only 46% (369 of 802). This was improved by interview administration to 77.4% (164 of 212). Logistic regression analysis revealed that self-completion, cognitive dysfunction, disability and age were all independently associated with poor overall response rates. Among those patients who returned a completed questionnaire, completion of individual questions sufficient to calculate a valid score was variable. Only 62.5% of inpatients who self-completed a questionnaire gave sufficient response to calculate a score on the mental health subscale, compared with 93.7% of general practice patients. CONCLUSION: The self-administered questionnaire is unacceptable for older hospital inpatients. Use of an interviewer improves response, but factors which influence health status, such as physical and cognitive dysfunction, have a significant effect on response rates. Therefore the utility of the SF-36 in its present form as a routine health status measure for use in older hospital inpatients is questioned.

A comparative study of women with chronic pelvic pain, chronic nonpelvic pain and those with no history of pain attending general practitioners.

OBJECTIVE: To investigate and compare the demographic and psychosocial profiles of women with chronic pelvic pain, chronic pain in a different site, and those with no history of pain with specific reference to a history of sexual abuse. DESIGN: A prospective comparative study. SETTING: Pelvic Pain Clinic at Leicester General Hospital NHS Trust, Pain Management Clinic at Leicester Royal Infirmary NHS Trust and two General Practices. PARTICIPANTS: Thirty women with chronic pelvic pain, 30 women with chronic pain in a different site and 30 women attending their general practitioner with no history of pain. INTERVENTIONS: A specifically designed patient profile questionnaire to identify and explore incidents of sexual and physical abuse was administered to each woman by a research psychologist for confidential self-completion. Data were also collected on other demographic, medical and psychosocial characteristics. RESULTS: Women with chronic pelvic pain were found to have a higher lifetime prevalence of sexual abuse, involving penetration or other genital contact compared with the two comparison groups. The prevalence of physical abuse was the same in all groups. Women in the pelvic pain group were more likely to have approached their GP for symptoms not related to pelvic pain than women in the other two groups and the incidence of clinical anxiety was significantly higher in this group compared with the pain-free group. The prevalence of sexual problems was much higher in the group with pelvic pain compared with the other two groups. CONCLUSION: These findings indicate that women with chronic pelvic pain have a higher incidence of past sexual abuse compared with women in a comparison pain group and with women with no pain.
