Proactive and Integrated Management and Empowerment in Parkinson's Disease: Designing a New Model of Care.

Parkinson's disease is the second most common neurodegenerative condition after Alzheimer's disease. The number of patients will rise dramatically due to ageing of the population and possibly also due to environmental issues. It is widely recognised that the current models of care for people with Parkinson's disease or a form of atypical parkinsonism lack continuity, are reactive to problems rather than proactive, and do not adequately support individuals to self-manage. Integrated models of care have been developed for other chronic conditions, with a range of positive effects. A multidisciplinary team of professionals in the United Kingdom and the Netherlands, all with a long history of caring for patients with movement disorders, used knowledge of deficiencies with the current model of care, an understanding of integrated care in chronic disease and the process of logic modelling, to develop a novel approach to the care of patients with Parkinson's disease. We propose a new model, termed PRIME Parkinson (Proactive and Integrated Management and Empowerment in Parkinson's Disease), which is designed to manage problems proactively, deliver integrated, multidisciplinary care, and empower patients and their carers. It has five main components: (1) personalised care management, (2) education and empowerment of patients and carers, (3) empowerment of healthcare professionals, (4) a population health approach, and (5) support of the previous four components by patient- and professional-friendly technology. Having mapped the processes required for the success of this initiative, there is now a requirement to assess its effect on health-related and quality of life outcomes as well as determining its cost-effectiveness. In the next phase of the project, we will implement PRIME Parkinson in selected areas of the United Kingdom and the Netherlands.

The past, present, and future of telemedicine for Parkinson's disease.

Travel distance, growing disability, and uneven distribution of doctors limit access to care for most Parkinson's disease (PD) patients worldwide. Telemedicine, the use of telecommunications technology to deliver care at a distance, can help overcome these barriers. In this report, we describe the past, present, and likely future applications of telemedicine to PD. Historically, telemedicine has relied on expensive equipment to connect single patients to a specialist in pilot programs in wealthy nations. As the cost of video conferencing has plummeted, these efforts have expanded in scale and scope, now reaching larger parts of the world and extending the focus from care to training of remote providers. Policy, especially limited reimbursement, currently hinders the growth and adoption of these new care models. As these policies change and technology advances and spreads, the following will likely develop: integrated care networks that connect patients to a wide range of providers; education programs that support patients and health care providers; and new research applications that include remote monitoring and remote visits. Together, these developments will enable more individuals with PD to connect to care, increase access to expertise for patients and providers, and allow more-extensive, less-expensive participation in research.

Prevalence and incidence of acute and chronic comorbidity in patients with squamous cell carcinoma of the head and neck.

BACKGROUND: Limited data exist on the burden of comorbidity among patients with squamous cell head and neck cancer (SCCHN) before and during cancer treatment. METHODS: The precancer prevalence and incidence rates of 8 comorbid conditions were estimated among a population-based cohort of 1499 patients with SCCHN in the Netherlands. Patients with cancer, treatments, and comorbidities were identified in the PHARMO Record Linkage System (RLS) using hospital admissions and/or dispensing codes. Prevalence proportions and incidence rates were also compared against a matched cancer-free population. RESULTS: Cardiovascular (41%) and respiratory diseases (12%) were the most prevalent comorbidities. Incidence rates of most comorbidities were highest the first 6 months after cancer diagnosis and decreased over time. Patients receiving chemotherapy-based treatment had significantly higher incidence rates of anemia and other malignant diseases. CONCLUSIONS: High rates of acute and chronic comorbidity were observed; knowledge of comorbidity burden aids in establishing a benefit-risk profile for investigational SCCHN therapies.

Increased risk of infectious disease requiring hospitalization among patients with psoriasis: a population-based cohort.

BACKGROUND: Immunologic alterations caused by psoriasis and/or its therapies may affect the risk of serious infections. OBJECTIVE: For patients with psoriasis, we explored the overall and therapy-related risk of contracting an infectious disease (ID) requiring hospitalization in a large population-based cohort. METHODS: The incidence of ID was compared between patients with psoriasis and a randomly selected cohort (ratio 1:5) using hospital and pharmacy databases covering 2.5 million Dutch residents between 1997 and 2008. First and multiple IDs were defined and categorized into 20 groups based on primary International Classification of Diseases, Ninth Revision, Clinical Modification discharge diagnoses. Multivariate Cox regression and Poisson event-count models were used to test the risk difference of IDs between patients with psoriasis and reference cohort. RESULTS: A total of 25,742 patients with psoriasis and 128,710 reference subjects were followed up for approximately 6 years. The likelihood of IDs in patients with psoriasis was twice as high as the reference population (908 vs 438 events/100,000 person-years, crude hazard ratio 2.08, 95% confidence interval 1.96-2.22). In a multivariate model the hazard ratio decreased to 1.54 (95% confidence interval 1.44-1.65). This risk was highest for patients with more severe psoriasis (adjusted hazard ratio 1.81, 95% confidence interval 1.57-2.08), but was not associated with recent systemic antipsoriatic drug dispensing. Respiratory tract, abdominal, and skin infections occurred most frequently in patients with psoriasis. Multiple event analysis that counted the total number of infectious discharge diagnoses gave similar results. LIMITATIONS: No data were available on lifestyle factors. CONCLUSION: The risk of severe infections was significantly higher for patients with psoriasis compared with control subjects and could not be explained by exposure to systemic antipsoriatic drugs.

Quality of life in relation to constipation among opioid users.

OBJECTIVE: Opioid users often experience constipation. In this study the impact of constipation on QoL was assessed in patients using opioids either for non-advanced illness or advanced illness. METHODS: Patients using opioids, recruited via public pharmacies, were asked to complete questionnaires on opioid use, constipation and the EuroQol five-dimension questionnaire (EQ-5D). Patients with a severe non-curable disease and relatively short life-expectancy were classified as having an advanced illness; a disabling yet not directly life-threatening condition was defined as non-advanced illness. Constipation was assessed based on questions on opioid side-effects and laxative use. EQ-5D index scores were compared between patients with and without constipation using Wilcoxon two-samples test. RESULTS: Questionnaires were returned by 588 patients with non-advanced illness, of whom 326 (55%) were classified as having constipation and by 113 patients with advanced illness, of whom 76 (67%) were classified as having constipation. The median EQ-5D index, a weighted health state index score with 1 = full health, was lower in patients with constipation than in patients without constipation (0.31 vs. 0.65, p< 0.01 for non-advanced illness and 0.41 vs. 0.61, p=0.12 for advanced illness). CONCLUSION: The results of this study suggest that, in patients using opioids either for non-advanced illness or advanced illness, constipation negatively influences QoL. By separately analysing patients with advanced illness and patients with non-advanced illness, possible selective non-response and confounding was accounted for, but not completely solved.

Determination of non-treatment with statins of high risk patients in The Netherlands.

OBJECTIVE: To determine in the Netherlands what proportions of high risk patients with established cardiovascular disease (CVD) or diabetes mellitus type 2 (DM2) who were not treated with statins on 1 January 2007 and which characteristics were associated with non-treatment. METHODS: From the IPCI GP database patients were selected who were registered with a GP on 1 January 2007 who had a history of either CVD (CVD patients), DM2 (diabetics) or both (diabetics with CVD). The proportion of patients using statins around 1 January 2007 was determined. Associations of patient characteristics with non-treatment were quantified (CVD patients and diabetics only). RESULTS: In all, 19 628 CVD patients, 5006 diabetics and 3767 diabetics with CVD were identified. Of these patients 71%, 54% and 45%, respectively did not use statins. These proportions were similar in the subgroups of patients with recent LDL-C measurements. Among these subgroups the vast majority of non-treated patients was eligible for statin treatment (LDL-C >2.5 mmol/l). The proportion of statin-treated patients was larger among diabetics than among CVD patients. Among CVD patients, female gender, age below 40 years, living in a deprived area, a history of CVD of less than 1 year and arrhythmia were significantly associated with non-treatment. Among diabetics, significant associations were: living in a deprived area and specialist visits in the previous year. In 2003, treatment rates among diabetics were lower, but among CVD patients they were similar. This suggests that the higher treatment rates among diabetics compared to CVD patients in 2007 may be the result of disease-management programmes introduced for diabetics in 2004. CONCLUSION: The majority of patients with established CVD or DM2 were not treated with statins on 1 January 2007. Eligibility for statin treatment may have been overestimated due to unavailability of cholesterol levels among many non-treated patients. Implementation of care programmes for CVD patients may increase treatment rates among eligible CVD patients.
