The hospital burden of disease associated with bone metastases and skeletal-related events in patients with breast cancer, lung cancer, or prostate cancer in Spain

POCKETT R.D., CASTELLANO D., MCEWAN P., OGLESBY A., BARBER B.L. & CHUNG K. (2010) European Journal of Cancer Care19, 755–760 The hospital burden of disease associated with bone metastases and skeletal-related events in patients with breast cancer, lung cancer, or prostate cancer in Spain Metastatic bone disease (MBD) is the most common cause of cancer pain and of serious skeletal-related events (SREs) reducing quality of life. Management of MBD involves a multimodal approach aimed at delaying the first SRE and reducing subsequent SREs. The objective of the study was to characterise the hospital burden of disease associated with MBD and SREs following breast, lung and prostate cancer in Spain. Patients admitted into a participating hospital, between 1 January 2003 and 31 December 2003, with one of the required cancers were identified and selected for inclusion into the study. The index admission to hospital, incidence of patients admitted and hospital length of stay were analysed. There were 28 162 patients identified with breast, lung and prostate cancer. The 3 year incidence rates of hospital admission due to MBD were 95 per 1000 for breast cancer, 156 per 1000 for lung cancer and 163 per 1000 for prostate cancer. For patients admitted following an SRE, the incidence rates were 211 per 1000 for breast cancer, 260 per 1000 for lung cancer and 150 per 1000 for prostate cancer. This study has shown that cancer patients consume progressively more hospital resources as MBD and subsequent SREs develop.

A comparison of intermediate and long-acting insulins in people with type 2 diabetes starting insulin: an observational database study

Aims:  Insulin is normally added to oral glucose‐lowering drugs in people with type 2 diabetes when glycaemic control becomes suboptimal. We evaluated outcomes in people starting insulin therapy with neutral protamine Hagedorn (NPH), detemir, glargine or premixed insulins.

Purpose, development and use of injury indicators.

Injury indicators can be used to give policy makers an estimate of the scale of injuries and their long term effects. They can help compare injury levels in different areas and countries and can be used to help measure the effectiveness of interventions. Work on severity related indicators is promising. However there are no perfect indicators to date as many are hampered with difficulties in case definition and under reporting. For example, mortality rates are affected by improvements in care even if the incidence of an injury remains the same, the abbreviated injury scale (AIS) takes 10–20 minutes to code and so is not used in health service databases, surveys have problems with recall bias, definition of injury and response rates. If we accept that we need to make the best out of imperfect indicators and imperfect data then we should use multiple sources of data and accept that no one indicator can be used universally but needs to be selected for the purpose. For example, one possible new indicator of the incidence of non-fatal injury might be fracture data in the emergency department. Fractures are painful and so nearly always end up with a hospital attendance. This might give a means to compare incidence of non-fatal injury in different areas and countries. In conclusion, we need injury indicators to progress in injury prevention. Imperfect indicators can be used for targeting and evaluating interventions as long as we know and adjust for their limitations.

Paediatric hospital admissions for rotavirus gastroenteritis and infectious gastroenteritis of all causes in England: an analysis of correlation with deprivation

Abstract Objectives: Infectious intestinal diseases cause substantial morbidity and economic loss in the UK. Rotavirus gastroenteritis (RVGE), a form of gastroenteritis, is the primary cause of severe diarrhoea in children. The primary objective of this study was to examine whether hospitalisation for gastroenteritis, and particularly RVGE, is linked to social deprivation. Methods: A retrospective study relating to hospital admissions in England with rotavirus, gastroenteritis, or type 1 diabetes mellitus (T1DM) was conducted in children aged under 5 years between 1st April 2009 and 31st March 2010 using the CHKS database. Admissions with selected diagnoses were extracted based on ICD-10 coding. Deprivation data were obtained from the Index of Multiple Deprivation (IMD) 2007 for England. Results: A total of 20,571 unique hospital admissions were made by children, in England, with RVGE (n = 1334; 6.5%) together with a diagnosis of infectious gastroenteritis of all causes (n = 19,237; 93.5%), giving an overall hospital admission rate, for those aged under 5 years, of 65.7 per 10,000 population. With ‘rank of average score’ and the ‘rank of average rank’ as measures of deprivation, the rate of hospital admissions with gastroenteritis of all causes decreased by 0.346 and 0.287 per 10,000 (p < 0.001) respectively for every unit increase in deprivation rank (decreasing deprivation), though this trend was not observed in patients admitted with RVGE specifically. Conclusions: Hospital admissions with gastroenteritis of all causes increased as deprivation increased. The implementation of a rotavirus vaccination programme would help to reduce the burden of RVGE and gastroenteritis of all causes, and in the context of gastroenteritis, some elements of health and social inequality may be vaccine preventable. Limitations: It is possible that the study is limited by the accuracy and completeness of deprivation indices, and coding within CHKS; the existence of the ‘ecological fallacy’ must also be considered.

The economic burden of posttransplant events in renal transplant recipients in Europe.

Background This study aims to describe the healthcare resource utilization and costs of managing renal posttransplant patients over 3 years posttransplant in nine European countries and to stratify them by year 1 glomerular filtration rate (GFR). Methods A retrospective observational and database analysis of renal transplant patients and a physician questionnaire study were conducted to collect recipient and donor characteristics, posttransplant events, and healthcare resource utilization related to these posttransplant events. In each country, local published costs were applied to the resource use identified. The results were stratified by the patient GFR reading at a time point 1 year after renal transplant. Results The database study identified 3,181 patients who met the inclusion criteria, along with 2,818 transplants carried out in the centers surveyed by questionnaire. Total 3-year costs derived from the questionnaire analysis vary depending on local treatment practices, from a minimum of &OV0556;33,602 per patient in the Czech Republic to &OV0556;77,461 per patient in the Netherlands. Consistently across countries, estimated costs appear to decrease with improved graft functioning status (increased GFR) at 1 year. The average 3-year costs, discounting immunosuppresion therapy and certain posttransplant events, per patient with a GFR greater than or equal to 60 at 1 year are estimated to be around 35% lower than those with 15⩽GFR<30. Conclusion This study demonstrates that in Europe, worsening posttransplant renal function may contribute to substantive increases in resource use, with some variation across regions. Therefore, management strategies that promote renal function after transplantation have the potential to provide important resource savings.

Burden of Illness in UK Subjects with Reported Respiratory Infections Vaccinated or Unvaccinated against Influenza: A Retrospective Observational Study

Objective Detailed data are lacking on influenza burden in the United Kingdom (UK). The objective of this study was to estimate the disease burden associated with influenza-like illness (ILI) in the United Kingdom stratified by age, risk and influenza vaccination status. Methods This retrospective, cross-sectional, exploratory, observational study used linked data from the General Practice Research Database and the Hospital Episode Statistics databases to estimate resource use and cost associated with ILI in the UK. Results Data were included from 156,193 patients with ≥1 general practitioner visit with ILI. There were 21,518 high-risk patients, of whom 12,514 (58.2%) were vaccinated and 9,004 (41.8%) were not vaccinated, and 134,675 low-risk patients, of whom 17,482 (13.0%) were vaccinated and 117,193 (87.0%) were not vaccinated. High-risk vaccinated patients were older (p<0.001) and had more risk conditions (p<0.001). High-risk (odds ratio [OR] 2.16) or vaccinated (OR 1.19) patients had a higher probability of >1 general practitioner visit compared with low-risk and unvaccinated patients. Patients who were high-risk and vaccinated had a reduced risk of >1 general practitioner visit (OR 0.82; p<0.001). High-risk individuals who were also vaccinated had a lower probability of ILI-related hospitalisation than individuals who were high-risk or vaccinated alone (OR 0.59). In people aged ≥65 years, the mortality rate was lower in vaccinated than unvaccinated individuals (OR 0.75). The cost of ILI-related GP visits and hospital admissions in the UK over the study period in low-risk vaccinated patients was £27,391,142 and £141,932,471, respectively. In low-risk unvaccinated patients the corresponding values were £168,318,709 and £112,534,130, respectively. Conclusions Although vaccination rates in target groups have increased, many people are still not receiving influenza vaccination, and the burden of ILI in the United Kingdom remains substantial. Improving influenza vaccination uptake may have the potential to reduce this burden.

A comparison of healthcare resource use for rotavirus and RSV between vulnerable children with co-morbidities and healthy children: a case control study

Abstract Objective: To quantify the differences in hospital length of stay (LOS) and cost between healthy and vulnerable children with cystic fibrosis (CF), insulin-dependent diabetes mellitus (IDDM), cancer, and epilepsy who contract rotavirus (RVGE) or respiratory syncytial virus (RSV). Methods: Hospital Episode Statistics (HES) data were collected for England, for children <5 years old, admitted between April 2001 and March 2008, using ICD-10 codes for RVGE and RSV. Cases were identified as having RVGE and/or RSV plus CF, IDDM, cancer, or epilepsy. Healthy controls had RVGE and/or RSV only, additional controls had eczema only. Cost, hospital LOS, and demographics were collected. Results: Four hundred and eighty-six (0.5%) cases and 101,784 (99.5%) healthy controls were admitted with RVGE or RSV, with 17,420 eczema controls. RVGE was present in 153 (31.5%) cases and 7532 (7.4%) healthy controls, and RSV in 333 (68.5%) cases and 94,252 (92.6%) healthy controls. Cases were older (1.1 years, SD = 1.3 years), had greater LOS (9.9 days, SD = 19.9), and cost more (£3477, SD = £7765) than healthy controls (age = 0.2, SD = 0.5, p < 0.001; LOS = 1.9 days, SD = 3.1, p < 0.001; cost = £595, SD = £727, p < 0.001). Cost for cases was 6-times greater than healthy controls (p < 0.001). Controls had a 0.3 day greater LOS (p < 0.001) with RSV, but a £17 (p = 0.085) lower mean cost than RVGE. Conclusion: RVGE and RSV are more serious diseases in vulnerable children, requiring more intense resource use. The importance of preventing infection in vulnerable children is underlined by hygiene and appropriate isolation and vaccination strategies. When universal vaccination is under consideration, as for rotavirus vaccines, evaluation of a vaccination programme should consider the potentially positive impact on vulnerable children. Limitations: Limitations of the study include a dependency on accurate coding, an expectation that patients are identified through laboratory testing, and the possibility of unidentified underlying conditions affecting the burden.

Survey of digestive health across Europe: Final report. Part 2: The economic impact and burden of digestive disorders

Digestive diseases – gastrointestinal and liver disorders – are common across Europe, causing more than 500 000 deaths in 2008 in the 28 EU member states (and more than 900 000 deaths in the whole of Europe, including Russia and other non-EU states). However, United European Gastroenterology (UEG) believe that these diseases are poorly understood, have usually attracted relatively little attention from a policy perspective and do not attract significant research funding, in comparison with many other disciplines. One of the remits of the UEG is to raise the political and public awareness of gastrointestinal disorders throughout Europe. To facilitate this, accurate and up to date information is required on the human and health consequences and on the economic burden of digestive disorders.

Assessment of resource use and costs associated with parathyroidectomy for secondary hyperparathyroidism in end stage renal disease in the UK.

Abstract Introduction: Secondary hyperparathyroidism (SHPT) is a major complication of end stage renal disease (ESRD). For the National Health Service (NHS) to make appropriate choices between medical and surgical management, it needs to understand the cost implications of each. A recent pilot study suggested that the current NHS healthcare resource group tariff for parathyroidectomy (PTX) (£2071 and £1859 in patients with and without complications, respectively) is not representative of the true costs of surgery in patients with SHPT. Objective: This study aims to provide an estimate of healthcare resources used to manage patients and estimate the cost of PTX in a UK tertiary care centre. Methods: Resource use was identified by combining data from the Proton renal database and routine hospital data for adults undergoing PTX for SHPT at the University Hospital of Wales, Cardiff, from 2000–2008. Data were supplemented by a questionnaire, completed by clinicians in six centres across the UK. Costs were obtained from NHS reference costs, British National Formulary and published literature. Costs were applied for the pre-surgical, surgical, peri-surgical, and post-surgical periods so as to calculate the total cost associated with PTX. Results: One hundred and twenty-four patients (mean age = 51.0 years) were identified in the database and 79 from the questionnaires. The main costs identified in the database were the surgical stay (mean = £4066, SD = £,130), the first month post-discharge (£465, SD = £176), and 3 months prior to surgery (£399, SD = £188); the average total cost was £4932 (SD = £4129). From the questionnaires the total cost was £5459 (SD = £943). It is possible that the study was limited due to missing data within the database, as well as the possibility of recall bias associated with the clinicians completing the questionnaires. Conclusion: This analysis suggests that the costs associated with PTX in SHPT exceed the current NHS tariffs for PTX. The cost implications associated with PTX need to be considered in the context of clinical assessment and decision-making, but healthcare policy and planning may warrant review in the light of these results.
