Excess burden of constipation in Parkinson's disease: a pilot study

An analysis was undertaken of clinic-based questionnaires that asked people with Parkinson's disease and a control group of older people without a known neurological condition about their experiences of constipation. People with Parkinson's disease report higher constipation on a validated objective measure, the Rome criterion (59% vs. 20.9%); a behavioral indicator, laxative-taking (38.4% vs. 14.2%); and subjective self-report of being always or often concerned by it (33.4% vs. 6.1%). Many people with Parkinson's disease experience constipation problems but they may not bring these to the attention of their healthcare providers. More research is required to understand the causes and management options.

A semantically enabled formalism for the knowledge management of Parkinson's disease

Bio-ontology is a formal representation of biological concepts that is used in the interchange of communication between computers and humans alike. They can then be used in the formulation and retrieval of knowledge. In developing a knowledge-based system for Parkinson's Disease, a procedure of knowledge map was used to capture and harness the intellectual resources of an organization, and new paradigms for knowledge mapping were also formulated. Knowledge bases for symptoms and drugs, physiotherapy, speech and language therapy, and dieting that affect patient care were developed. Finally, the knowledge bases were merged to form a single central repository of knowledge base.

Understanding of blood pressure and behavioural risk factors amongst British adolescents

OBJECTIVES

To survey students aged 16-18 years in secondary education establishments in one school district in the south of England in order to: assess knowledge about the importance of blood pressure (BP) for health; investigate associations between knowledge and health-related behaviours; and explore home, school and health service influences on knowledge.

STUDY DESIGN

Observational.

METHODS

Self-reported data from a structured questionnaire administered to convenience samples of students in schools were analysed by Chi-squared tests and multiple linear regression. The questionnaire assessed knowledge about BP risks, symptoms, consequences and measurement, and collected information on BP-related instruction, health behaviours (smoking, exercise, alcohol and nutrition) and family background.

RESULTS

A cross-section of 569 students completed questionnaires, representing 19.6% of the total age cohort. Most students recognized the major behavioural risks and consequences of high BP, but 104 (18.3%) could not describe how BP is measured, and 401 (88.1%) had no idea what a normal BP reading should be. In multivariate analysis, BP knowledge was associated with previous academic attainment, having received advice or instruction about BP, and having BP measured in the last 2 years. Family experience was not significant. Many students reported unhealthy behaviours: current smoker (n = 87, 15.3%); less than three exercise sessions per week (n = 172, 30.2%); and two portions or less of fruit/vegetables per day (n = 223, 39.2%). BP knowledge was significantly associated with regular exercise but not with other health-promoting behaviours. One hundred and twenty-one (21.3%) students acknowledged having received instruction about BP, mainly from doctors/nurses (32%) and schools (28%).

CONCLUSION

Gaps in adolescents' knowledge about BP were identified. Greater awareness was associated with having received formal advice and instruction, so health services and schools could play an important part in improving BP knowledge among adolescents. More understanding of cumulative risks may encourage fuller engagement in health-promoting activities.

Delayed transfers of older people from hospital: Causes and policy implications

Health and social care agencies in the UK. have been under pressure for some time to reduce delayed transfers of older people from hospital because they absorb scarce health service resources and incur a human cost through inappropriate placement. A local study based on an analysis of records and interviews with managers showed that delays reflect the complex needs of older people, and arise from financing and organisational problems at both the planning and implementation stages of a discharge. Family resistance may also be a factor. Budgetary constraints result in delays in confirming public support for some clients. Shortages of professional staff and care assistants limit the provision of domiciliary packages. The contraction of the residential sector has reduced the availability of beds and increased the cost of care home placements. Scope exists for expediting administrative aspects of transfers by coordinating health and social services. More recent legislation that imposes fines on social service departments for delayed transfers does not address underlying causes.

Rehabilitation for Parkinson's disease: a systematic review of available evidence

OBJECTIVE

To systematically review the available evidence on the effectiveness of nonpharmacological rehabilitation interventions for people with Parkinson's disease, and identify future research needs.

DESIGN

Electronic searches of four databases (CINAHL, Cochrane Library, MEDLINE, PsychLIT) 1980-2002; examination of reference lists of relevant papers. Controlled trials and observational studies were included. Data extraction and quality assessment of papers by two independent reviewers. A narrative review.

SETTING

Rehabilitation interventions delivered either in subjects' own homes, or in clinical settings as outpatients.

SUBJECTS

Community-living adults with Parkinson's disease.

INTERVENTIONS

Physiotherapy, occupational therapy, speech and language therapy, psychological counselling and support, and education.

MAIN MEASURES

A range of outcomes: mobility, functional status, speech, swallowing, psychological well-being, as determined by the studies included in the review.

RESULTS

Forty-four different studies (reported in 51 papers) were included (25 physiotherapy, 4 occupational therapy, 10 speech and language therapy, 3 psychological counselling, 1 educational, 1 multidisciplinary). All studies, except one, reported improvements on at least one outcome measure.

CONCLUSIONS

Findings may reflect publication bias, but suggest interventions can affect patients' lives for the better in a variety of ways. It is difficult to interpret the clinical importance of statistically significant improvements reported in most studies. There is a need for methodologically more robust research with meaningful follow-up periods, designed in a manner that separates specific and nonspecific effects. Cost-effectiveness evidence is required to provide clear guidance on service extensions.

Educational and psychosocial programmes for adolescents with diabetes: approaches, outcomes and cost-effectiveness

Diabetes incurs heavy personal and health system costs. Self-management is required if complications are to be avoided. Adolescents face particular challenges as they learn to take responsibility for their diabetes. A systematic review of educational and psychosocial programmes for adolescents with diabetes was undertaken. This aimed to: identify and categorise the types of programmes that have been evaluated; assess the cost-effectiveness of interventions; identify areas where further research is required. Sixty-two papers were identified and subjected to a narrative review. Generic programmes focus on knowledge/skills, psychosocial issues, and behaviour/self-management. They result in modest improvements across a range of outcomes but improvements are often not sustained, suggesting a need for continuous support, possibly integrated into normal care. In-hospital education at diagnosis confers few advantages over home treatment. The greatest returns may be obtained by targeting poorly controlled individuals. Few studies addressed resourcing issues and robust cost-effectiveness appraisals are required to identify interventions that generate the greatest returns on expenditure.

Multidisciplinary rehabilitation for people with Parkinson's disease: a randomised controlled study

OBJECTIVE

To determine whether a programme of multidisciplinary rehabilitation and group support achieves sustained benefit for people with Parkinson's disease or their carers.

METHODS

The study was a randomised controlled crossover trial comparing patients and carers who had received rehabilitation four months before assessment with those who had not. Patients were recruited from a neurology clinic, attended a day hospital from home weekly for six weeks using private car or hospital transport, and received group educational activities and individual rehabilitation from a multidisciplinary team. Patients were assessed at entry and at six months using a 25 item self assessment Parkinson's disease disability questionnaire, Euroqol-5d, SF-36, PDQ-39, hospital anxiety and depression scale, and timed stand-walk-sit test. Carers were assessed using the carer strain index and Euroqol-5d.

RESULTS

144 people with Parkinson's disease without severe cognitive losses and able to travel to hospital were registered (seven were duplicate registrations); 94 had assessments at baseline and six months. Repeated measures analysis of variance comparing patients at the 24 week crossover point showed that those receiving rehabilitation had a trend towards better stand-walk-sit score (p = 0.093) and worse general and mental health (p = 0.002, p = 0.019). Carers of treated patients had a trend towards more strain (p = 0.086). Analysis comparing patients before and six months after treatment showed worsening in disability, quality of life, and carer strain.

CONCLUSIONS

Patients with Parkinson's disease decline significantly over six months, but a short spell of multidisciplinary rehabilitation may improve mobility. Follow up treatments may be needed to maintain any benefit.

The relative health related quality of life of veterans with Parkinson's disease

OBJECTIVES

To use databases of the US Veterans Health Administration (VHA) to describe the impact of Parkinson's disease on health related quality of life (HRQoL) of veterans; to compare the HRQoL of veterans with Parkinson's disease with that of veterans reporting eight other neurological or chronic conditions; and to estimate the unique effect of Parkinson's disease on HRQoL.

METHODS

Respondents to the VHA 1999 large national health survey of veteran enrollees with a diagnosis of Parkinson's disease in VHA treatment files for the fiscal years 1997-1999 were identified by merging databases. The survey incorporated the Veterans SF-36, a well validated generic measure of HRQoL and functional status. This was used to compare patient groups. Mean physical (PCS) and mental (MCS) component summary scores were calculated for Parkinson's disease and eight other diseases by multivariable regressions that adjusted for age, sex, race, education, and 15 mental and physical co-morbid conditions that were self reported in the survey.

RESULTS

Of 887 775 survey respondents, 14 530 (1.64%) had a Parkinson's disease diagnosis. Controlling for sociodemographic factors and co-morbidities, veterans with Parkinson's disease had PCS and MCS below veterans with angina/coronary heart disease, arthritis, chronic low back pain, congestive heart failure, diabetes, and stroke. Veterans with spinal cord injury reported slightly lower PCS than veterans with Parkinson's disease (32.38 v 32.72; 0.03 of 1 SD). Veterans with depression reported markedly lower MCS than veterans with Parkinson's disease (35.94 v 41.48; 0.55 of 1 SD). The unique effect of having Parkinson's disease on HRQoL was to lower PCS and MCS by 4.10 and 3.42 points (0.41 and 0.34 of 1 SD), respectively.

CONCLUSIONS

The analysis quantifies the negative impact of Parkinson's disease on HRQoL, after controlling for sociodemographic factors and co-morbidities. Compared with eight other chronic conditions, Parkinson's disease imposes a relatively heavy burden on US veterans in the VHA health care system.

Short-term effectiveness of intensive multidisciplinary rehabilitation for people with Parkinson's disease and their carers

OBJECTIVE

To evaluate the short-term effectiveness of an intensive multidisciplinary rehabilitation programme for people with Parkinson's disease and their carers.

DESIGN

Observational, with assessments before and after intervention.

SETTING

An elderly care day unit in a district general hospital in south-east England.

SUBJECTS

One hundred and eighteen people with Parkinson's disease and no cognitive impairment, and their carers.

INTERVENTION

Participants attended the day hospital in groups of six patients with their carers for one day per week over six consecutive weeks. After assessment, they received individual treatment from a specialist team. Weekly group activities included relaxation and talks from experts.

OUTCOME MEASURES

Patients and carers were assessed for: health-related quality of life, psychological well-being, social services need, perceptions of the programme. Patients were additionally assessed for mobility, gait and speech. Carers were assessed for strain.

RESULTS

After treatment significant improvements were recorded in patients' mobility and gait (p < 0.05), speech (p < 0.001), depression (p = 0.029), health-related quality of life (p = 0.001). People with more advanced disease at baseline gained significantly more from treatment (p < or = 0.04). Carers were less depressed and had higher health-related quality of life than patients at baseline (p < 0.001) and no improvements in these indicators were recorded after treatment. A high unmet need for social services was identified in 31% of participants, and 10% of carers were found in danger of being unable to continue caring. Participants reported knowledge gains and high levels of satisfaction with both individual therapies and group activities.

CONCLUSIONS

This intensive co-ordinated programme provided immediate benefits to people with Parkinson's disease and their carers.

Health system costs of in-hospital cardiac arrest

This paper reports on the health system resources used in the treatment of in-hospital cardiac arrests in a British district general hospital. The resources used in resuscitation attempts were recorded prospectively by observation of a convenience sample of 30 cardiac arrests. The post-resuscitation resource use by survivors was collected through a retrospective record review (n = 37) and by following survivor members in the prospective sample (n = 6). Financial data were used to translate resource use into costs (1999 prices). There was a non-significant trend for more resources to be used in daytime resuscitations than at night. Survivors had significantly fewer diagnostic tests during resuscitation than those who died (P = 0.004). Length of resuscitation attempt was positively and significantly related to resource use (P < 0.05). The average variable cost per resuscitation attempt (1999 prices) was 195.66 pounds sterling; 76.5% was for staff, and 13.1% for drugs and fluids. Emergency calls were attended by an average of 10.11 staff. The average fixed cost per resuscitation attempt was 928.81 pounds sterling; 12% for capital equipment and 73% for staff training. The average post-resuscitation costs attributable to the cardiac arrest of the 29 people surviving more than 24 h after cardio-pulmonary resuscitation (CPR) were estimated to be 1,589.72 pounds sterling. This is lower than other studies which estimated total costs of post-CPR lengths of stay. Reducing avoidable cardiac arrests would generate in-hospital savings in direct resuscitation care of survivors. Scope for reducing capital and training costs is discussed.

Effects of educational and psychosocial interventions for adolescents with diabetes mellitus: a systematic review

BACKGROUND

Insulin-dependent diabetes mellitus, also known as type 1 diabetes, is a life-threatening condition and is the third most common chronic illness among young people. As a result of minimal or non-existent insulin production, people with diabetes must take over the normally automatic task of regulation of blood glucose levels. This is achieved by a complex regimen involving multiple, daily administrations of insulin coordinated with dietary intake and energy expenditure and monitored by blood glucose testing.

OBJECTIVES

To examine the effectiveness of educational and psychosocial interventions for adolescents with type 1 diabetes designed to improve their diabetes management. Specifically, it addressed the following research questions: (1) Do educational and psychosocial interventions for adolescents with type 1 diabetes have beneficial effects on biological and psychosocial outcomes? (2) Are there types or features of interventions that have been shown to be more effective than others? (3) What evidence is there of the cost-effectiveness of interventions?

METHODS

A search strategy was formulated, piloted and refined. Three journals were handsearched, 11 electronic databases were searched and personal contacts, flyers, conferences and websites were used to notify the research community of the review to access further literature. This process generated 10,535 abstracts, which, after screening, resulted in 367 articles identified for retrieval. This number was augmented by hand-searching, personal contact and exploding references, and a final total of 457 articles were scrutinised. Of these, 64 reports describing 62 studies were identified as empirical papers evaluating educational or psychosocial interventions. The relevant data were extracted from the papers and summary tables for each study were prepared. Where possible, effect sizes were computed for outcomes from studies that included a randomised control group (CG) and other relevant information.

RESULTS

A descriptive analysis of the 62 studies was undertaken. Most studies (67.7%) were conducted in the USA and 41% were randomised controlled trials (RCTs), none of which were UK-based. Only 48% of the reports provided an explicit theoretical rationale for the intervention. The mean number of participants was 53.8. The studies took place in various settings, evaluated a variety of interventions, involved various interventionists, addressed various components and assessed the effects by a range of outcomes, including measures of metabolic control and psychological and behavioural outcomes. Follow-up assessments were relatively rare. RESULTS - THE EFFECTIVENESS OF INTERVENTIONS: The 25 RCTs were examined in more detail and three of the most effective were described in depth. Effect sizes could be calculated for 14 studies. The mean (pooled) effect size for psychosocial outcomes was 0.37 and 0.33 for glycated haemoglobin with outliers (0.08 without outliers), indicating that these interventions have small to medium beneficial effects on diabetes management outcomes. A narrative review of the 21 pre-post studies with no CG was performed, including evaluations of interventions conducted at summer camps, interventions for poorly controlled patients and educational interventions. All studies reported beneficial effects. RESULTS - COST-EFFECTIVENESS: Few studies addressed economic considerations associated with interventions, and the lack of information on costs and the diversity of outcomes included by investigators impeded cost- effectiveness comparisons. Shorter hospitalisation at diagnosis is at least as effective in achieving control and avoiding complications in adolescence as longer stays. Home care may result in improved outcomes but may not be cheaper than hospital care at diagnosis. Targeting poorly controlled subjects may reduce adverse events and hospitalisations and may be more cost-effective than generic interventions. There is a need for rigorous cost-effectiveness studies of educational and psychosocial interventions for adolescents with type 1 diabetes that include longer-term considerations.

CONCLUSIONS

The following conclusions were drawn from this review: (1) Educational and psychosocial interventions have small to medium beneficial effects on various diabetes management outcomes. (2) Well-designed trials of such interventions are needed in the UK (no completed RCTs of educational or psychosocial interventions for adolescents with type 1 diabetes conducted in the UK were found). (3) The evidence, arising primarily from studies in the USA, provides a starting point for the design of interventions in the UK. (4) Quantitative and narrative analysis of the evidence suggested that interventions are more likely to be effective if they demonstrate the inter-relatedness of the various aspects of diabetes management.

Hypertension awareness, detection and treatment in a university community: results of a worksite screening

This study aimed to assess knowledge levels, explore the extent of undiagnosed hypertension, record previous screening activity and monitor the outcomes of previous hypertension treatment. To this end, information was collected from volunteer members of a university community, by means of a self-report questionnaire, about their personal characteristics, knowledge and experience of hypertension and stroke, and previous blood pressure measurements. In addition, their current blood pressure was recorded. A total of 653 staff and students completed the questionnaire and had their blood pressure measured. Analysis revealed that 82% were normotensive (diastolic blood pressure <90 mmHg). Hypertension was significantly associated with age, self-reported excess weight P<0.001) and marginally with self-reported non-healthy eating (P=0.06). Of the volunteers, 57% could not provide an accurate definition of a stroke. Knowledge levels were significantly and positively related to experience of stroke, healthy eating, not smoking and a recent blood pressure check. Of the respondents, 30% stated that they had not had their blood pressure measured in the previous two years. 51% of known hypertensives were not controlled. 68% of volunteers with diastolic blood pressure >89 mmHg were previously unaware of a potential hypertension problem. Hypertension rates amongst the university volunteers are higher than those recently recorded from a population sample. Scope exists for increasing knowledge and awareness, and for raising both screening rates and treatment outcomes. Improvements in these areas are required if current public health targets for heart disease and stroke are to be achieved. Worksite screening programmes can contribute to this endeavour.

Behavioral interventions for adolescents with type 1 diabetes: how effective are they?

OBJECTIVE

To evaluate the effectiveness of behavioral interventions for adolescents with type 1 diabetes based on a systematic review of the literature.

RESEARCH DESIGN AND METHODS

The literature was identified by searching 11 electronic databases, hand-searching 3 journals from their start dates, and contacting individual researchers. Only articles that reported evaluations of behavioral (including educational and psychosocial) interventions for adolescents (age range 9-21 years) with type 1 diabetes that included a control group were included in the present review. Data summarizing the key features of the interventions and their effects were extracted from each article. Where possible, effect sizes for the randomized control trials (RCTs) were calculated.

RESULTS

The search process identified 64 reports of empirical studies. Of these, 35 studies included a control group, and 24 were RCTs. Effect sizes could be calculated for 18 interventions. The overall mean effect size calculated across all outcomes was 0.33 (median 0.21), indicating that these interventions have a small- to medium-sized beneficial effect on diabetes management. Interventions that were theoretically based were significantly more effective than those that were not (P<0.05, 1-tailed).

CONCLUSIONS

Research to date indicates that these interventions are moderately effective. Several methodological weaknesses to be avoided in future studies are noted. It is also recommended that investigators use the reach, efficacy, adoption, implementation, and maintenance (RE-AIM) framework to guide the design of future studies, which should result in more disseminable interventions. RE-AIM assesses the intervention's reach, or percent or representativeness of patients willing to participate; efficacy across a range of outcomes; adoption, or the percent and representativeness of settings willing to implement the intervention; implementation, or the consistency of the delivery of the intervention as intended; and maintenance, or the extent to which delivery of the intervention becomes a routine part of health care in the medical setting.

Health-related quality of life in neurology

CONTEXT

In a climate of growing concern about costs of health care, professional accountability, and the effectiveness and efficiency of treatment, neurologists should understand measures of health-related quality of life (HRQoL) and appreciate both their values and their limits.

OBJECTIVE

To provide a critical review of current concepts in the measurement of HRQoL, with particular emphasis on those pertaining to neurologic conditions.

DESIGN

A selective overview of measurement strategies and specific instruments.

SETTING

Clinical and research settings.

PARTICIPANTS

Special attention to people with such conditions as multiple sclerosis and Parkinson disease.

MAIN OUTCOME MEASURES

The utility and relevance to neurologists of available measures of HRQoL.

RESULTS

There are both generic and condition- or disease-specific measures of HRQoL. Though many measures do not elicit response or are even offensive to people with such conditions as multiple sclerosis and Parkinson disease, other measures pertain directly to their circumstances and needs.

CONCLUSIONS

Measures of HRQoL are both meaningful and relevant to neurologists. However, they must be refined-enabled-and used in combinations to address the clinical and existential realities of many neurologic conditions. Arch Neurol. 2000;57:1224-1227

Explaining breast cancer mortality in England: the effect of socioeconomic factors and health care services

England has the worst mortality rate for breast cancer in the developed world. Using area-level data for 145 health districts in England, this study seeks to explain variations in breast cancer mortality among women aged 50-64 years in the period before the National Breast Screening Programme became operational. It is found that socioeconomic and behavioural factors had a larger effect on mortality than did health care inputs. This might be explained both by inadequacies in the data, and by the fact that, in the absence of screening, cancers tend to be detected at a later stage, by which time the chances of a successful outcome are reduced. It is suggested that the impact of health care services in reducing mortality will increase in the future as screening becomes widespread and results in earlier detection and treatment. The prioritization of screening is central to achieving the reductions in mortality from breast cancer specified in the Health of the Nation targets.

Role of screening in reducing invasive cervical cancer registrations in England

OBJECTIVE

To estimate the effect of screening on invasive cervical cancer registrations in England.

SETTING

The Health of the Nation target for cervical cancer seeks to reduce the incidence of invasive cases (ICD 180) by at least 20% between 1986 and 2000.

METHOD

The available area-level statistics on invasive cervical cancer registrations, screening activity, and socioeconomic and behavioural characteristics for 145 district health authorities in England over the period 1985-91 were collected. A multiple regression analysis sought to explain variations in incidence rates by relating screening and socioeconomic and behavioural variables to registration rates.

RESULTS

Districts with higher unemployment levels and higher numbers of pregnancies in young women had higher registration rates for invasive cervical cancer. The cervical smear rate for women aged 35-64 in a district was positively related to registrations, whereas the relation was negative for the 20-34 age group.

CONCLUSIONS

The higher registration rates for invasive cervical cancer in districts with higher cervical smear rates for women aged 35-64 may reflect historically lower screening cover. The negative relation between the cervical smear rate and invasive cervical cancer registrations in women aged 20-34 is accompanied by high registration rates for preinvasive (CIN III) cervical cancer (ICD 233.1). For the advantages of the Pap test to be fully realised, and for invasive cervical cancer registrations to fall in line with the Health of the Nation targets, a comprehensive screening programme, with a high take up rate is required. The various changes to the screening programme introduced since 1988 should help to achieve this. Public health policy should focus on educating the population about the risk factors for cervical cancer and the significance of screening.

Chronic liver disease associated with high hepatic copper concentration in a dog

An 8-month-old dog admitted for routine castration was found to have ascites. Liver biopsy revealed inflammation, fibrosis, and a copper concentration of 1,300 ppm on a dry weight basis. As cirrhosis developed, the copper concentration decreased without chelator treatment. At necropsy, the dog had cirrhosis, but the hepatic copper concentration was only 730 ppm.

Ergonomic principles basic to hand tool design

A survey of those features of hand tools relevant to the physical interaction between the implement and the human operator. Concepts basics to the optimization of forces are mentioned, followed by a description of some of the more common physiological problems and musculoskeletal complaints associated with improper hand tool and design and usage. An account of the distribution of contact pressures and possible consequences, if these are excessive, is followed by a description of the role of working gloves as related to ergonomic problems and their possible relationships to occupational diseases of the hand and wrist. Some aspects of anatomy and anthropometry pertinent to the optimization of posture, motion patterns and tool size precede a list of desirable features for power tools. A glossary is included as an aid to the reader. The concepts and situations described are applicable to the design and use of the vast majority of hand tools.
