Economic evaluation of chronic disease self-management for people with diabetes: a systematic review.

AIMS: To systematically review the evidence on the costs and cost-effectiveness of self-management support interventions for people with diabetes. BACKGROUND: Self-management support is the provision of education and supportive interventions to increase patients' skills and confidence in managing their health problems, potentially leading to improvements in HbA1c levels in people with diabetes. METHODS: Randomized controlled trials, observational studies or economic modelling studies were eligible for inclusion in the review. The target population was adults with diabetes. Interventions had to have a substantial component of self-management support and be compared with routine care. Study quality was evaluated using the Consensus on Health Economic Criteria and International Society of Pharmacoeconomic Outcomes Research questionnaires. A narrative review approach was used. RESULTS: A total of 16 costing and 21 cost-effectiveness studies of a range of self-management support interventions were identified. There was reasonably consistent evidence across 22 studies evaluating education self-management support programmes suggesting these interventions are cost-effective or superior to usual care. Telemedicine-type interventions were more expensive than usual care and potentially not cost-effective. There was insufficient evidence regarding the other types of self-management interventions, including pharmacist-led and behavioural interventions. The identified studies were predominantly of poor quality, with outcomes based on short-term follow-up data and study designs at high risk of bias. CONCLUSIONS: Self-management support education programmes may be cost-effective. There was limited evidence regarding other formats of self-management support interventions. The poor quality of many of the studies undermines the evidence base regarding the economic efficiency of self-management support interventions for people with diabetes.

Economic evaluation of robot-assisted hysterectomy: a cost-minimisation analysis.

OBJECTIVE: The aim of this study was to carry out an economic evaluation of robot-assisted hysterectomy compared with the current standard of care in Ireland. DESIGN: Cost-minimisation analysis of robot-assisted hysterectomy compared with a combination of traditional open and conventional laparoscopic surgery. SETTING: The publicly funded healthcare system in Ireland. POPULATION: The target population was women requiring hysterectomy that could be completed using robot-assisted surgery. METHODS: A simulation-based economic evaluation model including data derived from a systematic review and local databases was used to estimate surgical costs. MAIN OUTCOME MEASURES: Incremental cost of robot-assisted surgery compared to current routine care. RESULTS: The incremental cost of robot-assisted hysterectomy is an estimated €3291 (95% confidence interval €2509-€4183) more than the existing mix of open and traditional laparoscopic surgery. The additional cost of robot-assisted surgery is primarily driven by the increased cost of surgical equipment, the robot, maintenance of the robot, and the cost of theatre staff due to longer operative times. The only significant factor reducing the cost of surgery is a shorter hospital stay relative to open surgery. CONCLUSIONS: Robot-assisted hysterectomy is more costly than the current mix of open and traditional laparoscopic surgery. Without longer-term or functional outcome data, the additional expense associated with robot-assisted hysterectomy may not be justified in a budget-constrained health system.

Diagnostic accuracy systematic review of rectal bleeding in combination with other symptoms, signs and tests in relation to colorectal cancer.

BACKGROUND: Rectal bleeding is a recognised early symptom of colorectal cancer. This study aimed to assess the diagnostic accuracy of symptoms, signs and diagnostic tests in patients with rectal bleeding in relation to risk of colorectal cancer in primary care. METHODS: Diagnostic accuracy systematic review. Medline (1966 to May 2009), Embase (1988 to May 2009), British Nursing Index (1991 to May 2009) and PsychINFO (1970 to May 2009) were searched. We included cohort studies that assessed the diagnostic utility of rectal bleeding in combination with other symptoms, signs and diagnostic tests in primary care. An eight-point quality assessment tool was produced to assess the quality of included studies. Pooled positive likelihood ratios (PLRs), sensitivities and specificities were calculated. RESULTS: Eight studies incorporating 2323 patients were included. Average weighted prior probability of colorectal cancer was 7.0% (range: 3.3-15.4%, median: 8.1%). Age > or = 60 years (pooled PLR: 2.79, 95% confidence interval (CI) 2.00-3.90), weight loss (pooled PLR: 1.89, 95% CI: 1.03-3.07) and change in bowel habit (pooled PLR: 1.92, 95% CI: 0.54-3.57) raise the probability of colorectal cancer into the range of referral to secondary care but do not conclusively 'rule in' the diagnosis. Presence of severe anaemia has the highest diagnostic value (pooled PLR: 3.67, 95% CI: 1.30-10.35), specificity 0.95 (95% CI: 0.93-0.96), but still only generates a post-test probability of 21.6%. CONCLUSIONS: In patients with rectal bleeding who present to their general practitioner, additional 'red flag' symptoms have modest diagnostic value. These findings have implications in relation to recommendations contained in clinical practice guidelines.

Using HIPE data as a research and planning tool: limitations and opportunities.

BACKGROUND: The Hospital Inpatient Enquiry (HIPE) system is an important information source for research and health service planning activities. However, as it was not designed explicitly for these purposes, some limitations exist. AIMS: To make recommendations that would increase the value of HIPE as a research and planning tool. METHODS: Experiences of using HIPE for research and planning exercises were analysed so as to identify its limitations and their impact on research and planning. RESULTS: Limitations were identified regarding data quality, policy issues and the general system. CONCLUSIONS: To increase the utility of HIPE as a research and planning tool, a number of changes are recommended, including: expanding the system to cover private hospitals and outpatient and emergency services; adopting routine small area and socio-economic coding; adopting unique personal identifiers; publishing regular detailed reports with in-depth analyses; and considering making hospital identifiers available in certain circumstances.

The potential impact on travel times of closure and redistribution of A&E units in Ireland.

Modelling has been used to estimate variations in travel time to Accident & Emergency (A&E) Departments for Acute Myocardial Infarction (AMI) and Road Traffic Accidents (RTA), taking into account three different distributions of A&E departments in the country. We have modelled three scenarios: current, the current distribution of A&E Departments; intermediate, two A&E Units for some Health Boards and one for others; and extreme, one A&E Department for each of the 10 Health Boards. The percentage of travel times that fall within an hour for AMI and RTA for the three scenarios (current, intermediate and extreme) are 85.6, 82.8, 70.0 and 81.8, 85.2, 71.8 percent respectively. While a redistribution of A&E Departments seems inevitable, a sensible modelling approach can be used to plan the new distribution of services to maintain equitable geographic access.

Getting a handle on the general practice workforce in Ireland.

BACKGROUND: General practice makes a critical contribution to healthcare in Ireland. However, there is a weak understanding of the general practice workforce in Ireland. AIMS: The aim of this study is to estimate the number of general practitioners (GPs) and practice nurses in Ireland. METHODS: A variety of data sources was used to corroborate counts of general practitioners and practice nurses. Capture-recapture methods were used to estimate the hidden population of GPs not identified by the databases included. RESULTS: There are 2,954 general practitioners in Ireland, equivalent to 64.4 per 100,000 population. There are 1,700 practice nurses nationally, equivalent to 37.1 per 100,000 persons. There is substantial regional variation in the number of general practitioners and practice nurses per 100,000. To some extent, deficits in one discipline may be counterbalanced by a surplus in the other. CONCLUSIONS: In the absence of a centralised register, it is not possible to track the number of GPs or practice nurses working in Ireland at present. This is despite the fact that there are twice as many general practice visits per annum compared to hospital visits.

Chronic respiratory disease and multimorbidity: prevalence and impact in a general practice setting.

BACKGROUND: Multimorbidity is defined as two or more co-existing chronic conditions in an individual and is common in general practice. It is associated with poorer outcomes for patients. This study aimed to establish the prevalence of multimorbidity in patients with chronic respiratory disease in general practice and to describe its impact on health service use. METHODS: Cross-sectional study based in general practice in Dublin. Drug and disease code searches were performed to identify adult patients with a diagnosis of chronic respiratory disease. Medical records were reviewed for chronic respiratory diagnosis, other chronic conditions, demographic characteristics, General Practitioner (GP) and practice nurse utilisation rates, and numbers of medications. RESULTS: In a general practice population of 16,946 patients 3.9% had chronic respiratory disease and 60% of these had one or more co-existing chronic condition(s). GP and practice nurse utilisation rates, and number of medications were significantly higher among those with multimorbidity compared with those with respiratory disease alone. Multivariate analysis showed that increasing age and low socio-economic status were significantly associated with multimorbidity. CONCLUSION: The majority of patients with chronic respiratory disease have multimorbidity. Clinical guidelines based on single disease entities and outcomes are not as easy to implement and may not be as effective in this group.

Influence of material deprivation on prescribing patterns within a deprived population.

OBJECTIVE: To study the effect of material deprivation on prescribing trends in primary care, using a locally derived deprivation score. METHODS: A retrospective analysis of prescribing trends linked to material deprivation by district electoral division (DED) in the Eastern Region of the General Medical Services in Ireland (population of 334,031) was performed. Standardised prescribing ratios were determined for a number of drug classes, including those that could be used to identify particular diseases for 181,647 patients who were assigned a locally derived material deprivation score. RESULTS: Prescribing rates for a number of medications including anti-asthma, nitrate and benzodiazepine medications increased, whilst the prescribing of other medications such as anti-parkinsonian and antidepressive agents decreased with increasing deprivation. CONCLUSIONS: Our results suggest that, even within a population considered to be economically deprived, different levels of deprivation may significantly influence general practitioner prescribing patterns. Within the group of centrally active medications, the prescription of symptomatic medications increased with increasing material deprivation, whilst the prescription of disease-specific medications decreased with increasing material deprivation.

Undergraduate training in the European Union. Convergence or divergence?

A survey of dental schools in the European Union was carried out for two main reasons. Firstly to promote the exchange of information in respect of curriculum objectives in the different countries and secondly to ascertain the differences in the interpretation of the 1978 EU sectoral directives for dental education and training. Out of 127 schools, only 30 responded, yet the information provided is of considerable importance. It demonstrates wide divergence in the interpretation of the 1978 Directives and methods of assessment of clinical competence. There is a considerable difference throughout Europe in hours devoted to the various subjects included in the Dental Directives. There is little evidence of convergence in methods of assessment or quality assurance. The survey demonstrates the difference in resources, levels of staff, availability of clinical training places, output in research and patient treatments throughout the European Union. The results question the effectiveness of the 1978 Dental Directives in promoting convergence of standards. As there is free movement of dentists throughout the European Union, it is concluded that a different approach may be necessary to ensure that all European Union dental graduates achieve comparable standards in their education and training.
