Evaluation of different models of general practitioners working in or alongside emergency departments: a mixed-methods realist evaluation.

Background: Emergency healthcare services are under intense pressure to meet increasing patient demands. Many patients presenting to emergency departments could be managed by general practitioners in general practitioner-emergency department service models. Objectives: To evaluate the effectiveness, safety, patient experience and system implications of the different general practitioner-emergency department models. Design: Mixed-methods realist evaluation. Methods: Phase 1 (2017-8), to understand current practice: rapid realist literature review, national survey and follow-up key informant interviews, national stakeholder event and safety data analysis. Phase 2 (2018-21), to collect and analyse qualitative (observations, interviews) and quantitative data (time series analysis); cost-consequences analysis of routine data; and case site data for 'marker condition' analysis from a purposive sample of 13 case sites in England and Wales. Phase 3 (2021-2), to conduct mixed-methods analysis for programme theory and toolkit development. Results: General practitioners commonly work in emergency departments, but delivery models vary widely in terms of the scope of the general practitioner role and the scale of the general practitioner service. We developed a taxonomy to describe general practitioner-emergency department service models (Integrated with the emergency department service, Parallel within the emergency department, Outside the emergency department on the hospital site) and present a programme theory as principal output of the study to describe how these service models were observed to operate. Routine data were of variable quality, limiting our analysis. Time series analysis demonstrated trends across intervention sites for: increased time spent in the emergency department; increased emergency department attendances and reattendances; and mixed results for hospital admissions. Evidence on patient experience was limited but broadly supportive; we identified department-level processes to optimise the safety of general practitioner-emergency department models. Limitations: The quality, heterogeneity and extent of routine emergency department data collection during the study period limited the conclusions. Recruitment was limited by criteria for case sites (time series requirements) and individual patients (with 'marker conditions'). Pandemic and other pressures limited data collection for marker condition analysis. Data collected and analysed were pre pandemic; new approaches such as 'telephone first' and their relevance to our findings remains unexplored. Conclusion: Findings suggest that general practitioner-emergency department service models do not meet the aim of reducing the overall emergency department waiting times and improving patient flow with limited evidence of cost savings. Qualitative data indicated that general practitioners were often valued as members of the wider emergency department team. We have developed a toolkit, based on our findings, to provide guidance for implementing and delivering general practitioner-emergency department services. Future work: The emergency care data set has since been introduced across England to help standardise data collection to facilitate further research. We would advocate the systematic capture of patient experience measures and patient-reported outcome measures as part of routine care. More could be done to support the development of the general practitioner in emergency department role, including a core set of competencies and governance structure, to reflect the different general practitioner-emergency department models and to evaluate the effectiveness and cost effectiveness to guide future policy.

Hospital emergency departments are under huge pressure. Patients are waiting many hours to be seen, some with problems that general practitioners could deal with. To reduce waiting times and improve patient care, arrangements have been put in place for general practitioners to work in or alongside emergency departments (general practitioner­emergency department models). We studied the different ways of working to find out what works well, how and for whom. We brought together a lot of information. We reviewed existing evidence, sent out surveys to 184 emergency departments, spent time in the emergency departments observing how they operated and interviewing 106 staff in 13 hospitals and 24 patients who visited those emergency departments. We also looked at statistical information recorded by hospitals. Two public contributors were involved from the beginning, and we held two stakeholder events to ensure the relevance of our research to professionals and patients. Getting reliable figures to compare the various general practitioner­emergency department set-ups (inside, parallel to or outside the emergency department) was difficult. Our findings suggest that over time more people are coming to emergency departments and overall waiting times did not generally improve due to general practitioner­emergency department models. Evidence that general practitioners might admit fewer patients to hospital was mixed, with limited findings of cost savings. Patients were generally supportive of the care they received, although we could not speak to as many patients as we planned. The skills and experience of general practitioners were often valued as members of the wider emergency department team. We identified how the care provided was kept safe with: strong leaders, good communication between different types of staff, highly trained and experienced nurses responsible for streaming and specific training for general practitioners on how they were expected to work. We have produced a guide to help professionals develop and improve general practitioner­emergency department services and we have written easy-to-read summaries of all the articles we published.

Cost of hepatocellular carcinoma to the national health service in England: a registry-based analysis.

OBJECTIVE: Hepatocellular carcinoma (HCC) incidence in the UK trebled between 1997 and 2017. With increasing numbers requiring treatment, understanding the likely impact on healthcare budgets can inform service planning and commissioning. The aim of this analysis was to use existing registry data to describe the direct healthcare costs of current treatments for HCC and estimate the impact on National Health Service (NHS) budgets. DESIGN: A retrospective data analysis based on the National Cancer Registration and Analysis Service cancer registry informed a decision-analytic model for England comparing patients by cirrhosis compensation status and those on palliative or curative treatment pathways. Potential cost drivers were investigated by undertaking a series of one-way sensitivity analyses. RESULTS: Between 1 January 2010 and 31 December 2016, 15 684 patients were diagnosed with HCC. The median cost per patient over 2 years was £9065 (IQR: £1965 to £20 491), 66% did not receive active therapy. The cost of HCC treatment for England over 5 years was estimated to be £245 million. CONCLUSION: The National Cancer Registration Dataset and linked data sets have enabled a comprehensive analysis of the resource use and costs of secondary and tertiary healthcare for HCC, providing an overview of the economic impact to the NHS England of treating HCC.

Effectiveness and cost-effectiveness of face-to-face and electronic brief interventions versus screening alone to reduce alcohol consumption among high-risk adolescents presenting to emergency departments: three-arm pragmatic randomized trial (SIPS Junior high risk trial).

BACKGROUND AND AIMS: Alcohol use increases throughout adolescence. Emergency department (ED) attendance is an opportunity for alcohol screening and brief intervention (ASBI), which is effective for adults. This trial evaluated the effectiveness and cost-effectiveness of ASBI compared with screening alone (SA) in high-risk adolescents. DESIGN, SETTING AND PARTICIPANTS: Multi-centre, three-group, single-blind, individually randomized trial with follow-ups after 6 and 12 months in 10 ED settings in England. From October 2014 to May 2015 we screened 3327 adolescents aged 14 to 18 years, of whom 756 (22.7%) scored at least 3 on the Alcohol Use Disorders Identification Test: consumption (AUDIT-C) and consented to participate in this trial. Mean age was 16.1 years; 50.2% were female and 84.9% were white. INTERVENTIONS: Interventions were personalized feedback and brief advice (PFBA), personalized feedback plus electronic brief intervention (eBI) and SA. MEASURES: The primary outcome was the weekly alcohol consumed in standard UK units (8 g ethanol) at 12 months post-randomization, derived from extended AUDIT-C. Economic outcomes included quality of life and service use, from perspectives of both the National Health Service and personal social services (NHS&PSS) and society. FINDINGS: At 12 months, mean weekly consumption was 2.99 [95% confidence interval (CI) = 2.38-3.70] standard units for the SA group, 3.56 (95% CI = 2.90, 4.32) for PFBA and 3.18 (95% CI = 2.50, 3.97) for eBI, showing no significant differences. The PFBA group consumed mean 0.57 (-0.36, 1.70) units more than SA; and eBIs consumed 0.19 (-0.71, 1.30) more. Bayes factors suggested lack of effectiveness explained non-significance. From the NHS&PSS perspective, economic analysis showed that PFBA and eBI were not cost-effective compared with SA: PFBA yielded incremental cost-effectiveness ratio of £6213 (-£736 843, £812 884), with the intervention having 54% probability of being cost-effective compared with SA at the £20 000 WTP threshold. CONCLUSIONS: In emergency departments in England, neither personalized feedback and brief advice nor personalized feedback plus electronic brief intervention showed evidence of being effective or cost-effective when compared with screening alone in reducing alcohol consumption among adolescents.

Nurse-led home-visitation programme for first-time mothers in reducing maltreatment and improving child health and development (BB:2-6): longer-term outcomes from a randomised cohort using data linkage.

OBJECTIVES: Measure effectiveness of family nurse partnership (FNP) home-visiting programme in reducing maltreatment and improving maternal health and child health, developmental and educational outcomes; explore effect moderators, mediators; describe costs. DESIGN: Follow-up of BB:0-2 trial cohort (ISRCTN:23019866) up to age 7 years in England using record linkage. PARTICIPANTS: 1618 mothers aged 19 years or younger and their firstborn child(ren) recruited to BB:0-2 trial at less than 25 weeks gestation and not mandatorily withdrawn from trial or opted out. Intervention families were offered up to a maximum of 64 home visits by specially trained nurses from pregnancy until firstborn child was 2 years old, plus usually provided health and social care support. Comparator was usual care alone. OUTCOME MEASURES: Primary outcome: state-verified child-in-need status recorded at any time during follow-up. SECONDARY OUTCOMES: referral to social services, child protection registration (plan), child-in-need categorisation, looked-after status, recorded injuries and ingestions any time during follow-up, early childcare and educational attendance, school readiness and attainment at key stage 1 (KS1), healthcare costs. RESULTS: Match rates for 1547 eligible children (1517 singletons, 15 sets of twins) were 98.3% (NHS Digital) and 97.4% (National Pupil Database). There was no difference between study arms in the proportion of children being registered as in need (adjusted OR 0.98, 95% CI 0.74 to 1.31), or for any other measure of maltreatment. Children in the FNP arm were more likely to achieve a good level of development at reception age (school readiness) (adjusted OR 1.24, 95% CI 1.01 to 1.52). After adjusting for birth month, children in FNP arm were more likely to reach the expected standard in reading at KS1 (adjusted OR 1.26, 95% CI 1.02 to 1.57). We found no trial arm differences for resource use and costs. CONCLUSIONS: FNP did not improve maltreatment or maternal outcomes. There was evidence of small advantages in school readiness and attainment at KS1. TRIAL REGISTRATION NUMBER: ISRCTN23019866.

Brief interventions to prevent excessive alcohol use in adolescents at low-risk presenting to Emergency Departments: Three-arm, randomised trial of effectiveness and cost-effectiveness.

BACKGROUND: Alcohol consumption and related harm increase rapidly from the age of 12 years. We evaluated whether alcohol screening and brief intervention is effective and cost-effective in delaying hazardous or harmful drinking amongst low-risk or abstaining adolescents attending Emergency Departments (EDs). METHODS: This ten-centre, three-arm, parallel-group, single-blind, pragmatic, individually randomised trial screened ED attenders aged between 14 and 17 years for alcohol consumption. We sampled at random one third of those scoring at most 2 on AUDIT-C who had access to the internet and, if aged under 16, were Gillick competent or had informed consent from parent or guardian. We randomised them between: screening only (control intervention); one session of face-to-face Personalised Feedback and Brief Advice (PFBA); and PFBA plus an electronic brief intervention (eBI) on smartphone or web. We conducted follow-up after six and 12 months. The principal outcomes were alcohol consumed over the 3 months before 12-month follow up, measured by AUDIT-C; and quality-adjusted life-years. FINDINGS: Between October 2014 and May 2015, we approached 5,016 eligible patients of whom 3,326 consented to be screened and participate in the trial; 2,571 of these were low-risk drinkers or abstainers, consuming an average 0.14 units per week. We randomised: 304 to screening only; 285 to PFBA; and 294 to PFBA and eBI. We found no significant difference between groups, notably in weekly alcohol consumption: those receiving screening only drank 0.10 units (95% confidence interval 0.05 to 0.18); PFBA 0.12 (0.06 to 0.21); PFBA and eBI 0.10 (0.05 to 0.19). INTERPRETATION: While drinking levels remained low in this population, this trial found no evidence that PFBA with or without eBI was more effective than screening alone in reducing or delaying alcohol consumption.

Resource use and direct medical costs of acute respiratory illness in the UK based on linked primary and secondary care records from 2001 to 2009.

BACKGROUND: Previous studies have shown that influenza is associated with a substantial healthcare burden in the United Kingdom (UK), but more studies are needed to evaluate the resource use and direct medical costs of influenza in primary care and secondary care. METHODS: A retrospective observational database study in the UK to describe the primary care and directly-associated secondary care resource use, and direct medical costs of acute respiratory illness (ARI), according to age, and risk status (NCT Number: 01521416). Patients with influenza, ARI or influenza-related respiratory infections during 9 consecutive pre-pandemic influenza peak seasons were identified by READ codes in the linked Clinical Practice Research Datalink (CPRD) and Hospital Episodes Statistics (HES) dataset. The study period was from 21st January 2001 to 31st March 2009. RESULTS: A total of 156,193 patients had ≥1 general practitioner (GP) episode of ARI, and a total of 82,204 patients received ≥1 GP prescription, at a mean of 2.5 (standard deviation [SD]: 3.0) prescriptions per patient. The total cost of GP consultations and prescriptions equated to £462,827 per year per 100,000 patients. The yearly cost of prescribed medication for ARI was £319,732, at an estimated cost of £11,596,350 per year extrapolated to the UK, with 40% attributable to antibiotics. The mean cost of hospital admissions equated to a yearly cost of £981,808 per 100,000 patients. The total mean direct medical cost of ARI over 9 influenza seasons was £21,343,445 (SD: £10,441,364), at £136.65 (SD: £66.85) per case. CONCLUSIONS: Extrapolating to the UK population, for pre-pandemic influenza seasons from 2001 to 2009, the direct medical cost of ARI equated to £86 million each year. More studies are needed to assess the costs of influenza disease to help guide public health decision-making for seasonal influenza in the UK.

Lumbar fusion for lytic spondylolisthesis: Is an interbody cage necessary?

STUDY DESIGN: This study was a retrospective observational study. PURPOSE: The purpose of the study was to determine the radiological and clinical outcome of using locally sourced autologous bone graft in the surgical management of single-level lumbar lytic spondylolisthesis. BACKGROUND: Many spinal surgeons supplement pedicle screw fixation of lumbar spondylolisthesis with cages. In developing countries, the high cost of interbody cages has precluded their use, with surgeons resorting to filling the interbody space with different types of bone graft instead. This study reports on the clinical and radiological outcome of posterior lumbar interbody fusions for low-grade lytic spondylolisthesis using locally sourced autologous bone graft. MATERIAL AND METHODS: Posterior interbody fusion was performed in 22 consecutive patients over 18-month period, using (BRAND) pedicle screw system and locally sourced bone graft, i.e., bone removed during neural decompression. There were no postoperative restrictions, and all patients underwent clinical outcome measurements using Oswestry Disability Index (ODI), visual analogue pain score (VAS) at a minimum follow-up of 12 months, and computed tomography (CT) assessment of fusion with intraobserver validation by radiology consultant blinded, at 6 and12 months. Nearly 50% of the population were smokers. RESULTS: There was significant clinical improvement in ODI, VAS back pain, and VAS leg pain (P < 0.001). By contrast, the radiologic fusion rate measured by CT at 12 months was less satisfactory at 64%. There was no difference in clinical outcome between the fused group and nonfused population. CONCLUSIONS: These results indicate that the use of locally sourced bone graft in single-level lumbar lytic low-grade spondylolisthesis. Interbody fusion provides good clinical outcomes. The use of an interbody cage may not be clinically necessary. Our radiologic outcome, however, shows inferior fusion rates compared with published data. Future research will focus on long-term outcomes.

The expandable transforaminal lumbar interbody fusion - Two years follow-up.

STUDY DESIGN: This was a retrospective, observational study. OBJECTIVES: We hypothesize that the expandable transforaminal lumbar interbody fusion (TLIF) cage achieves satisfactory clinical outcomes while allowing for safe placement, improvement, and maintenance of foraminal and disc dimensions at 24 months postsurgery with low risk of cage migration, subsidence, and nerve injury. METHODS: TLIF with expandable cages was performed in 54 patients (62 levels) over a 24-month-period using open midline or minimally invasive surgery techniques with placement of Globus Caliber, Rise, or Altera expandable cages. All patients underwent clinical and radiological assessment at 6 weeks, 6 months, 1, and 2 years postoperatively. Clinical outcome was measured by Oswestry disability index (ODI), visual analog pain score for both back and leg (visual analog scores [VASs]). Radiological assessment was done by X-ray standing lateral position. RESULTS: There were significant clinical improvements in ODI, VAS leg, and VAS back at all postoperative time points. Disc height, foraminal height, focal Cobb angle, and global Cobb angle were significantly increased and maintained at all time points for 24 months (P < 0.001). Dural tear occurred in one patient (1.9%). There were neither intra- or postoperative neurological complications nor cage subsidence nor migration. CONCLUSIONS: These preliminary results indicate that the use of an expandable interbody cage achieves good clinical outcomes by improving and maintaining foraminal dimensions and disc height with minimal complication rate.

Prospective utility study of patients with multiple cardiovascular events.

OBJECTIVES: The effects of acute coronary syndrome (ACS) events on health-related quality-of-life (HRQoL) and the time dependency of these effects are unknown. This study aimed to characterize health utilities in ACS patients to aid development of future economic models estimating the cost per quality-adjusted life-year impact of ACS events and potential treatments. METHODS: Multi-center, non-interventional, longitudinal evaluation of health utility in patients experiencing ACS or stroke events. EuroQol-5 dimension 3 level (EQ-5D-3L) surveys were sent to patients (≥18 years) from three UK centers, 1 month after hospital discharge for myocardial infarction (MI), unstable angina (UA), or stroke. Patient demographics, lifestyle, and baseline utility score were collected in the first survey. Follow-up surveys were sent at 6, 12, 18, and 24 months to prospectively capture utility and subsequent health events. Two methods of patient identification were adopted-prospective, where the patient's qualifying events occurred after the study index date, and retrospective, where the patient's qualifying event occurred prior to the study index date. General healthy population utility values were assumed for pre-event HRQoL. RESULTS: Between January 2011 and March 2014, 2,103 prospectively (n = 1,350)/retrospectively (n = 753) identified patients (mean age = 68.3 years; 67.9% male) responded: MI = 55.9% (n = 1,176), UA = 42.7% (n = 898), stroke = 1.4% (n = 29); 24% had type 2 diabetes. Post-event utility values were lower than general healthy population values, although significant differences in utility between subsequent 6 (n = 1,031, change = -0.002), 12 (n = 1,096, change = -0.008), 18 (n = 1,246, change = -0.007), and 24 (n = 1,277, change = -0.004) month timepoints were not detected. Through multivariate regression analyses, wheelchair use, current smoking, and secondary mental and joint health events were associated with the greatest statistically significant utility decrements. CONCLUSIONS: This study indicates that health utility decreases following a cardiovascular event and, although some improvement occurs over the subsequent 24 months, general healthy population utility is not necessarily attained.

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.

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 immunosuppression 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.

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

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.

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

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.

Rotavirus, respiratory syncytial virus and non-rotaviral gastroenteritis analysis of hospital readmissions in England and Wales.

AIM: To quantify readmissions with infectious diseases and differences in readmission patterns. METHODS: Using the CHKS database, children <5 years admitted to hospital in England and Wales, between 2000 and 2008, with rotavirus (RV), respiratory syncytial virus (RSV) or non-rotaviral gastroenteritis (NRV) were identified. All admissions within a 30-day prior period were similarly identified, and the proportion of readmissions was calculated. RESULTS: There were 365,693 admissions for RV, RSV and NRV; 17.2% were readmissions. In 36% of cases, the cause of the prior admission was also RV, RSV or NRV, with 64% having a different prior diagnosis. The majority of readmissions were within 5 days of their prior admission, the majority of those with RV (n = 2,566/58.7%) within 3 days, NRV (n = 11 326/53.5%) within 4 days and RSV (n = 18 811/50.2%) within 9 days of prior discharge. Readmission for RV was associated with greater LOS than RSV (p < 0.001) and NRV (p < 0.001), while cost per admission was greater for RV compared to RSV (p < 0.001) and NRV (p < 0.001). CONCLUSIONS: Thirty-six percent of readmissions indicated discharge without resolution from the first admission; nosocomial infection needs to be considered as a cause in the other. Although RSV represented the largest readmission group, higher costs and longer LOS were associated with RV.

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

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.

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.
