Short- and long-term mortality following acute medical admission. QJM 2023; 116:850-854. [PMID: 37527010 DOI: 10.1093/qjmed/hcad181] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/12/2023] [Revised: 07/11/2023] [Indexed: 08/03/2023] Open
Abstract
BACKGROUND Short-term in-hospital mortality following acute medical admission has been widely investigated. Longer term mortality, particularly out-of-hospital mortality, has been less well studied. AIM The aim of this study is to evaluate short- and long-term mortality, and predictors of such, following acute medical admission. DESIGN Retrospective database study. METHODS We evaluated all acute medical admissions to our institution over 10 years (2002-11) with a minimum of a further 10 years follow-up to 2021 using the Irish National Death Register. Predictors of 30-day in-hospital and long-term mortality were analysed with logistic and Cox regression, with loss of life years estimated. RESULTS The 2002-11 cohort consisted of 62 184 admissions in 35 140 patients. 30-Day in hospital mortality (n = 3646) per patient was 10.4% and per admission was 5.9%. There were an additional 11 440 longer-term deaths by 2021-total mortality was 15 086 (42.9%). Deaths post hospital discharge had median age at admission of 75.4 years [interquartile range (IQR) 63.7, 82.8] and died at median age of 80 years (IQR 69, 87). The half-life of survival following admission was 195 months-representing a short fall of 8 life years (32.9%) compared with the projected population reference of 24.3 years. Age [odds ratio (OR) 1.73 (95% confidence interval (CI) 1.64, 1.81)], acute illness severity score [OR 1.39 (95% CI 1.36, 1.43)] and comorbidity score [OR 1.09 (95% CI 1.08, 1.10)] predicted long-term mortality. CONCLUSION Similar factors influence both short- and long-term mortality following acute medical admission, the magnitude of effect is attenuated over time.

Abstract
AIM To investigate the clinical predictive value of troponin (hscTnT) and blood culture testing. METHODS We examined all medical admissions from 2011-2020. Prediction of 30-day in-hospital mortality, dependent on blood culture and hscTnT requests/results, was evaluated using multiple variable logistic regression. Length of stay was related to utilization of procedures/services with truncated Poisson regression. RESULTS There were 77,566 admissions in 42,325 patients. With both blood cultures and hscTnT requested, 30-day in-hospital mortality increased to 20.9% (95%CI: 19.7, 22.1) vs 8.9% (95%CI: 8.5, 9.4) for blood cultures alone and 2.3% (95%CI: 2.2, 2.4) with neither. Blood culture 3.93 (95%CI: 3.50, 4.42) or hsTnT requests 4.58 (95%CI: 4.10, 5.14) were prognostic. CONCLUSION Blood culture and hscTnT requests and results predict worse outcomes.

Abstract
AIM To compare outcomes in Emergency Department (ED) final diagnoses of (non-specific complaint) NSC, dyspnoea and pain. METHODS We studied all ED final diagnoses of NSC, dyspnoea, and pain over 6 years (2015-2020). Multivariable logistic regression was performed. RESULTS There were 49,965 admissions. 30-day in-hospital mortality was significantly lower for pain, 3.0% (95%CI 2.4%, 3.6%), compared to NSC, 4.2% (95%CI 3.8%, 4.7%), and dyspnoea, 4.6% (95%CI 4.2%, 5.0%). NSC did not predict 30-day in-hospital mortality- univariate OR 1.05 (95%CI 0.93, 1.19), multivariable OR 1.07 (95%CI 0.93, 1.23). Comorbidity and Acute Illness Severity Scores demonstrated a curvilinear relationship with 30-day in-hospital mortality. CONCLUSION An ED final diagnosis of NSC did not predict 30-day in-hospital mortality.

Synthesising existing research on complicated grief in intellectual disability: findings from a systematic review. JOURNAL OF INTELLECTUAL DISABILITY RESEARCH : JIDR 2022; 66:833-852. [PMID: 36042575 PMCID: PMC9805198 DOI: 10.1111/jir.12973] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 01/21/2022] [Revised: 07/12/2022] [Accepted: 08/05/2022] [Indexed: 06/15/2023]
Abstract
BACKGROUND Complicated grief has been identified as a phenomenon in the general population, and there is an increasing body of research investigating complicated grief in people with intellectual disability. The aim of this study is to synthesise this existing knowledge from research published between 1999 and 2022. METHODS A structured systematic review using PRISMA guidelines was conducted, which searched three commonly used databases (Medline, PsycINFO and CINAHL) for research on the topic of bereavement and intellectual disability. The articles identified in this search were screened to identify those that addressed the issue of 'complicated grief', with all abstracts and subsequent full texts reviewed by two researchers. RESULTS In total, 179 abstracts were initially identified, with 34 articles eligible for full text screening and 18 papers reaching criteria for inclusion. Data relating to the studies' objectives were extracted under the headings of definition, defining principles, signs and symptoms, risk factors and treatments for complicated grief in intellectual disability. Thematic analysis of the extracted data was performed to identify key themes. CONCLUSIONS This review highlights that people with intellectual disability are likely to experience complicated grief reactions and that complicated grief is both underestimated and a clinically significant condition for people with intellectual disability. Future research should work to clarify diagnostic criteria and identify appropriate interventions.

Development of a machine-learning based model for predicting multidimensional outcome after surgery for degenerative disorders of the spine. EUROPEAN SPINE JOURNAL : OFFICIAL PUBLICATION OF THE EUROPEAN SPINE SOCIETY, THE EUROPEAN SPINAL DEFORMITY SOCIETY, AND THE EUROPEAN SECTION OF THE CERVICAL SPINE RESEARCH SOCIETY 2022; 31:2125-2136. [PMID: 35834012 DOI: 10.1007/s00586-022-07306-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/06/2022] [Revised: 05/04/2022] [Accepted: 06/24/2022] [Indexed: 01/20/2023]
Abstract
BACKGROUND It is clear that individual outcomes of spine surgery can be quite heterogeneous. When consenting a patient for surgery, it is important to be able to offer an individualized prediction regarding the likely outcome. This study used a comprehensive set of data collected over 12 years in an in-house registry to develop a parsimonious model to predict the multidimensional outcome of patients undergoing surgery for degenerative pathologies of the thoracic, lumbar or cervical spine. METHODS Data from 8374 patients (mean age 63.9 (14.9-96.3) y, 53.4% female) were used to develop a model to predict the 12-month scores for the Core Outcome Measures Index (COMI) and its subdomain scores. The data were split 80:20 into a training and test set. The top predictors were selected by applying recursive feature elimination based on LASSO cross validation models. Based on the 111 top predictors (contained within 20 variables), Ridge cross validation models were trained, validated, and tested for each of 9 outcome domains, for patients with either "Back" (thoracic/lumbar spine) or "Neck" (cervical spine) problems (total 18 models). RESULTS Among the strongest outcome predictors in most models were: preoperative scores for almost all COMI items (especially axial pain (back or neck) and peripheral pain (leg/buttock or arm/shoulder)), catastrophizing, fear avoidance beliefs, comorbidity, age, BMI, nationality, previous spine surgery, type and spinal level of intervention, number of affected levels, and surgeon seniority. The R2 of the models on the validation/test sets averaged 0.16/0.13. A preliminary online tool was programmed to present the predicted outcomes for individual patients, based on their presenting characteristics. https://linkup.kws.ch/prognostictool . CONCLUSION The models provided estimates to enable a bespoke prediction of the outcome of surgery for individual patients with varying degenerative pathologies and baseline characteristics. The models form the basis of a simple, freely-available online prognostic tool developed to improve access to and usability of prognostic information in clinical practice. It is hoped that, following confirmation of its validity and practical utility, the tool will ultimately serve to facilitate decision-making and the management of patients' expectations.

Abstract
BACKGROUND An 'unwell' patient is a common presentation. METHODS We studied all ED 'unwell' admissions over 6 years, assessing factors influencing mortality with logistic regression. RESULTS From 49,965 admissions, the ED diagnosis was 'unwell' in 3650 (7.3%). 'Unwell' presentations were older and had longer length of stay. Mortality was not different 4.2% vs 4.6 % (p=0.28). Respiratory patients and those >=70 years had increased mortality, 8.3% (95%CI: 5.9%, 10.6%) and 7.1% (5.7%, 8.4%) respectively. Being unwell predicted a better outcome - univariate OR 0.35 (95%CI: 0.24, 0.52), multivariable OR 0.68 (95%CI: 0.44, 1.03). CONCLUSION A diagnosis of 'unwell' applied to a heterogenous group; clinical trajectories and outcomes were sufficiently different to preclude targeted admission avoidance as a strategy.

Abstract
BACKGROUND Positive blood cultures predict mortality. The prognostic value of blood culture performance itself has not been fully defined. METHODS We evaluated medical admissions from 2002-2017. We defined blood culture category as 1) no culture 2) negative culture 3) positive culture. We employed a multivariable logistic regression model to evaluate outcomes. RESULTS We evaluated 78,568 blood cultures in 106,586 admissions. 30-day in-hospital mortality for no culture was 2.8% (95%CI 2.7, 2.9), culture negative 8.9% (95%CI 8.5, 9.3) and culture positive 16.7% (95%CI 15.5, 17.9). There was significant interaction between blood culture category and illness severity, OR 1.06 (95%CI 1.05, 1.08), and comorbidity, OR 1.09 (95%CI 1.09, 1.10). CONCLUSION Performance and results of blood cultures are independently associated with increased mortality.

Abstract
BACKGROUND Accurate efficient prognostication in acute medical admissions remains challenging. METHODS We constructed a Vital Sign based Risk Calculator using vital parameters and Major Disease Categories to predict 30-day in-hospital mortality using a multivariable fractional polynomial model. RESULTS We evaluated 113,807 admissions in 58,126 patients. The Vital Sign based Risk Calculator predicted 30-day inhospital mortality to increase from 2 points - 3.6% (95%CI 3.4, 3.7) to 12 points - 14.8% (95%CI 14.0, 15.7). AUROC was 0.74 (95%CI 0.72, 0.74). The addition of illness severity and comorbidity data improved AUROC to 0.90 (95%CI 0.89, 0.90). CONCLUSION The Vital Sign based Risk Calculator is limited by its simplicity; inclusion of illness severity and comorbidity data improve prediction.

Abstract
BACKGROUND The prediction of clinical outcomes using biochemical markers is an important tool. METHODS We calculated a risk score for all emergency admissions 2002-2017. We related potassium and mortality in a multivariable fractional polynomial model. We investigated the potassium distribution and relationship of potassium to mortality over time. RESULTS There were 106,586 admissions in 54,928 patients. Mortality was higher for those with an admission potassium above the median - 6.1% vs 4.6% (p<0.001), OR 1.07 (95%CI: 1.06, 1.09). There was a progressive increase in mortality from the lowest - 8.9% (95%CI: 8.3%, 9.4%) to highest potassium decile - 14.2% (95%CI: 13.5%, 14.8%). The frequency of admission hypokalaemia and the mortality at any given potassium decreased over time. CONCLUSION Admission potassium predicts mortality.

Socio-Economic Status and MultiOriginal morbidity - Fact or Fiction? Acute Med 2019; 18:64-70. [PMID: 31127794] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 06/09/2023]
Abstract
BACKGROUND Areas of low socio-economic status (SES) have a disproportionate number of emergency medical admissions; we quantitate the profile of multi-morbidity related to SES. METHODS We developed a logistic multiple variable regression model, based on over 15 years of hospital data, to examine the effect of socio-demography on hospital outcomes. RESULTS Admissions from low SES cohort were a decade younger, and had a shorter hospital stay, and lower 30-day episode mortality outcome. The number of morbidities was equivalent between groups, but the more disadvantaged were more likely to have a respiratory diagnosis or diabetes. CONCLUSION Low SES emergency admissions present > 10 yr. earlier than the high SES population; their equivalent multimorbidity, despite a lower age, could reflect accelerated disease progression.

Abstract
BACKGROUND There is concern that undue ED wait times may result in adverse outcomes. METHODS We studied 30-day in-hospital mortality (2002-2017) for all medical admissions (106,586 episodes; 54,928 patients) focusing on clinical risk profile. RESULTS Comparing 2002-09 vs. 2010-17, median ED waits > 6 hours (hr) increased 10h (95% CI: 8,13) to 15h (95% CI: 9,19). 30-day mortality declined 6.2% to 4.9%- (RRR- 20.8%/ NNT- 78). 30-day-mortality by ED wait: - < 4hr 6.6% (95% CI: 6.3%, 6.9%), 4-8hr 4.8% (95% CI: 4.6%, 5.0%), 8-12hr 4.3% (95% CI: 4.1%, 4.5%) or >=12hr 4.2% (95% CI: 3.9%, 4.5%). CONCLUSION Admissions with shorter waits are overrepresented with high clinical acuity. Higher Risk Score patient with extended wait times had worse clinical outcomes.

Abstract
Background We examined the effect of broadband access, educational status and their interaction on local population health. Methods We calculated the annual admission incidence rates for each small area population unit within our hospital catchment, relating quintiles of broadband access to two groups a) full time education to primary level (less than or equal to 15 years) and b) full time education to tertiary level (>18 years). Univariate and multivariable risk estimates were calculated, using truncated Poisson regression. Results 82,368 admissions in 44,628 patients were included. Broadband access was a linear predictor of the admission incidence rate with decreases from Q1 (least access) 50.8 (95%CI 30.2 to 71.4) to Q5 (highest access) 17.9 (95%CI 13.4 to 22.4). Areas with greater numbers educated only to primary level were more influenced by broadband access. Conclusion Broadband access is a predictor of the emergency medical admission rate; this effect is modulated by the baseline education level.

Abstract
BACKGROUND We previously reported weekend emergency admissions to have a higher mortality; we have now examined the time profile of deaths, by weekday or weekend admission, in all emergency medical patients admitted between 2002 and 2014. METHODS We divided admissions by a weekday or weekend (After 17.00 Friday-Sunday) hospital arrival. We examined survival following an admission using Cox proportional hazard models and Kaplan-Meier time to event analysis. RESULTS In total 82 368 admissions were recorded in 44, 628 patients. Weekend admissions had an increased mortality of 5.0% (95% CI 4.7, 5.4) compared with weekday admissions of 4.5% (95% CI 4.3, 4.7) ( P = 0.007). The univariate adjusted Odds Ratio (OR) of death for a weekend admission was significantly increased OR = 1.15 (95% CI 1.05, 1.24) ( P = 0.001). Mortality following an admission declined exponentially over time with a long tail, ∼25% of deaths occurred after day 28. Only 11.4% of deaths occurred on the weekend of the admission. Survival curves showed no mortality difference at 28 days ( P = 0.21) but a difference at 90 days ( P = 0.05). The higher mortality for a weekend admission was attributable to late deaths in the cohort with an extended stay; compared with weekday, these weekend admissions were more likely to be older and have greater co-morbidity. CONCLUSION Survival rates following a weekend or weekday admission were similar out to 28 days. The higher overall mortality for weekend admissions is due to divergence in survival between 28 and 90 days. Most deaths in weekend admissions occurred when the hospital was fully staffed.

Abstract
BACKGROUND The ageing of the population may be anticipated to increase demand on hospital resources. We have investigated the relationship between hospital episode costs and age profile in a single centre. METHODS All Emergency Medical admissions (33 732 episodes) to an Irish hospital over a 6-year period, categorized into three age groups, were evaluated against total hospital episode costs. Univariate and adjusted incidence rate ratios (IRRs) were calculated using zero truncated Poisson regression. RESULTS The total hospital episode cost increased with age ( P < 0.001). The multi-variable Poisson regression model demonstrated that the most important drivers of overall costs were Acute Illness Severity-IRR 1.36 (95% CI: 1.30, 1.41), Sepsis Status -1.46 (95% CI: 1.42, 1.51) and Chronic Disabling Disease Score -1.25 (95% CI: 1.22, 1.27) and the Age Group as exemplified for those 85 years IRR 1.23 (95% CI: 1.15, 1.32). CONCLUSION Total hospital episode costs are a product of clinical complexity with contributions from the Acute Illness Severity, Co-Morbidity, Chronic Disabling Disease Score and Sepsis Status. However age is also an important contributor and an increasing patient age profile will have a predictable impact on total hospital episode costs.

Abstract
BACKGROUND Patients from deprived backgrounds have a higher in-patient mortality following emergency medical admission. AIM To evaluate the influence of Deprivation Index, overcrowding and family structure on hospital admission rates. DESIGN Retrospective cohort study. METHODS All emergency medical admissions from 2002 to 2013 were evaluated. Based on address, each patient was allocated to an electoral division, whose small area population statistics were available from census data. Patients were categorized by quintile of Deprivation Index, overcrowding and family structure, and these were evaluated against hospital admission rate, calculated as rate/1000 population. Univariate and multivariable risk estimates (Odds Ratios or Incidence Rate Ratios) were calculated, using logistic or zero truncated Poisson regression as appropriate. RESULTS There were 66 861 admissions in 36 214 patients over the 12-year study period. Deprivation Index quintile independently predicted the admission rate, with rates of Q1 12.0 (95% CI 11.8-12.2), Q2 19.5 (95% CI 19.3-19.6), Q3 33.7 (95% CI 33.3-34.0), Q4 31.4 (95% CI 31.2-31.6) and Q5 38.1 (95% CI 37.7-38.5). Similarly the proportions of families with children <15 years old, was an independent predictor of the admission rate with rates of Q1 20.8 (95% CI 20.4-21.1), Q2 23.0 (95% CI 22.7-23.3), Q3 32.2 (95% CI 31.9-32.5), Q4 32.4 (95% CI 32.2-32.7) and Q5 37.2 (95% CI 36.6-37.8). The proportion of families with children ≥15-years old was also predictive but quintile of overcrowding was only predictive in the univarate model. CONCLUSION Deprivation Index and family structure strongly predict emergency medical hospital admission rates.

Abstract
BACKGROUND Deprivation Status increases the annual admission incidence of emergency medical admissions; the extent to which deprivation influences the admission of older persons is less well known. AIM To examine whether deprivation within a hospital catchment area influences emergency medical admissions for the elderly population. DESIGN The relationship between Deprivation Status, Dependency Ratio (population proportion of non-working age (<15 or ≥65 years) and age for all emergency admissions (82 368 episodes of 44 628 patients), over a 13-year period, were examined and ranked by quintile. METHODS Univariate and multi-variable risk estimates (incidence rate ratios) were calculated, using truncated Poisson regression. RESULTS The Dependency Ratio and the Deprivation index independently predicted the annual incidence rate of medical emergencies; however, when calculated for older persons, the corresponding incidence rate ratios showed a falling trend with increasing Deprivation Status-Q2 0.51 (95% confidence interval [CI]: 0.50, 0.52), Q3 0.59 (95% CI: 0.58, 0.60), Q4 0.51 (95% CI: 0.50, 0.52) and Q5 0.37 (95% CI: 0.36, 0.38). Thus, with increasing Deprivation Status, the proportion of total admission from the ≥65-year cohort fell substantially. CONCLUSION The admission incidence rate for emergency medical patients is strongly influenced by the catchment area Deprivation Status. However, because of its greater impact on the younger population, increasing deprivation alters the ratio of younger to older persons as a proportion of total emergency admissions.

Abstract
BACKGROUND The identification of high-risk patients could form a basis for targetted intervention following an emergency medical admission. METHODS All emergency admissions to our institution over 12 years (2002-13) were included. An Illness Severity method based on admission laboratory parameters, previously developed between 2002 and 2007, was investigated for the 2008-13 cohort. We compared the area under the receiver operating characteristic (AUROC) to predict a 30-day in-hospital death between the original and validating cohorts using logistic multiple variable analyses. We defined six risk subgroups, based on admission laboratory data and examined the frequency of 30-day in-hospital mortality within these subgroups. RESULTS About 66 933 admissions were recorded in 36 271 patients. Between 2002 and 2007, the 30-day in-hospital mortality was 11.3% but between 2008 and 2013 was 6.7% (P < 0.001). This represented an absolute risk reduction (ARR) of 4.6%, a relative risk reduction (RRR) of 41.0%, and a number needed to treat of 21.6. The laboratory model was similarly predictive in both cohorts-for 2002-07, the AUROC was 0.82 (95% CI 0.81, 0.82) and for 2008-13 was 0.82 (95% CI 0.81, 0.83). Two high-risk subgroups were identified within each cohort; for 2002-07, these contained 15.0 and 30.2% of admitted patients but 95.5% of in-hospital deaths. For 2008-13, these two groups contained 15.7 and 31.0% of admitted patients but 97.0% of in-hospital deaths. CONCLUSION A previously described laboratory score method, based on admission biochemistry, identified patients at high risk for an in-hospital death. Risk profiling at admission is feasible for emergency medical admissions and could offer a means to outcome improvement.

Comprehensive record keeping is a key aspect of medical practice. The National Hospitals Office (NHO) and Irish Medical Council (IMC) have published guidelines in this area. A prospective audit of 100 patients assessed by interns was performed to quantify adherence with these guidelines followed by an educational session and email reminders. Adherence was reassessed in an incidental manner. Compliance was recorded in a number of areas including the reason for review and documentation of a plan both 98 (98%). However less than half of interns recorded the patient's name, background history or their impression of the case. Only 31(31%) noted the patient's MRN and only 1(1%) the information they gave to the patient. Significant improvements following the intervention were found, however significant deficits remained in a number of areas including the noting of an impression of the case 62(62%) and information given to patients 18(18%). Suboptimal documentation can be improved through education and clinical auditing.

Chronic disabling disease--impact on outcomes and costs in emergency medical admissions. QJM 2015; 108:387-96. [PMID: 25336253 DOI: 10.1093/qjmed/hcu217] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/14/2014] [Indexed: 11/14/2022] Open
Abstract
BACKGROUND Chronic disabling disease is present in nearly 90% of emergency medical admissions. We have examined its impact on outcomes and costs in one institution, using a database of episodes collected prospectively over 12 years. METHODS All emergency admissions (66,933 episodes; 36,271 patients) to St James' Hospital over a 12-year period (2002-13) were evaluated in relation to 30-day in-hospital mortality, length of stay (LOS) and hospital costs. Predictor variables (identified univariately) were entered into a multi-variable logistic regression model to predict 30-day in-hospital mortality. The data were also modelled as count data (absolute LOS, total cost) using zero-truncated Poisson regression. RESULTS Acute illness severity was the best independent predictor of mortality; chronic disabling disease was an independent predictor (P < 0.001) for patients with 4+ disabling conditions. Age, adjusted for other predictors, was only independently predictive of mortality for patient 85+ years. Chronic disabling disease was an independent predictor of LOS increasing linearly with incidence rate ratios of 1.35 (95% CI: 1.29, 1.42), 1.59 (95% CI: 1.51, 1.66), 1.73 (95% CI: 1.65, 1.83) and 1.74 (95% CI: 1.65, 1.84) for those with 1, 2, 3 or 4+ disabling conditions, respectively. Age, as a predictor of LOS was strongly correlated with the presence of disabling disease. Chronic disabling disease independently predicted costs non-linearly; those with 2 or more disabling conditions had particularly high total hospital costs. CONCLUSION Chronic disabling disease is an independent predictor of hospital LOS and costs in unselected emergency admissions; adjusted for illness severity, it is only a mortality predictor for those with multiple disabling conditions.

Abstract
BACKGROUND Physician experience has been shown to improve clinical outcomes. Limited numbers of experienced clinicians make it unfeasible that they would care for all patients. We hypothesized that physician experience would impact outcomes for patients with high, but not low, risk of mortality. METHODS All emergency admissions from 2002 to 2013 were studied. Two groups at low and high risk for mortality (1.3% (95% CI: 1.13, 1.62) vs. 19.4% (95% CI: 18.5, 20.3)) were defined by a risk prediction method comprising acute Illness Severity Score, Charlson Comorbidity Index and sepsis status. Length of stay (LOS) and 30-day in-hospital mortality were the primary end points. Consultant experience was studied univariately and also entered into a multiple logistic regression model to predict 30-day in-hospital survival. A zero-truncated Poisson regression model assessed LOS and incidence rate ratios (IRR) were calculated. RESULTS Over the 12-year study period 66 933 admissions were recorded in 36 271 patients. High-risk patients cared for by more experienced (≥20 years qualified) physicians had a lower 30-day in-hospital mortality (19.4 vs. 17.1% P < 0.001), relative risk reduction 11.9%. The multivariable odds ratio of a 30-day in-hospital death for an experienced physician was 0.89 (95% CI: 0.82, 0.97; P = 0.009). LOS was shorter for high-risk patients allocated to experienced physicians with a multivariable IRR of 0.77 (95% CI: 0.94, 0.99; P = 0.02). No difference in outcomes was found for low-risk patients. CONCLUSION High-risk but not low-risk patients have improved outcomes when cared for by physicians with greater experience.

Abstract
BACKGROUND Air quality degraded by black smoke (particulate matter, PM10), sulphur dioxide (SO2) and nitrogen oxide (NO(x)) affects human health. Improvements following national legislation have lowered death rates. Whether background air pollution levels continue to affect human health remains unclear. AIM To determine impact of air pollutant concentrations (PM10, SO2 and NO(x)) on in-hospital mortality for acute medical admissions to St James's Hospital over a decade (2002-11). DESIGN All emergency admissions (55,596 episodes in n = 32,581 patients) were tracked prospectively and mortality assessed. Daily levels of PM10, SO2 and NO(x) were obtained from monitoring stations in our catchment area. METHODS Univariate and multivariate logistic regression was employed to examine relationships between pollutant concentration and odds ratio (OR) for death following adjustment for other mortality predictors. RESULTS Mortality related to each pollutant variable assessed (as quintiles of increasing atmospheric concentration) was significantly predictive. For PM10 and SO2, mortality in the highest three quintile concentrations (compared with base quintile) was significantly increased (P < 0.001) with univariate ORs of 1.24, 1.36 and 1.25 for PM10 and 1.43, 1.54 and 1.58 for SO2, respectively. Mortality in all quintile concentrations (compared with base quintile) was significantly increased (P < 0.05) for NO(x) with univariate ORs of 1.14, 1.18, 1.28 and 1.35, respectively. Following adjustment for other mortality predictors such as acute illness severity, all three air pollutants were independently predictive of mortality. CONCLUSION Despite improvement to air quality in Dublin, the prevailing background pollutant concentrations continue to affect human health at levels considered safe and below that previously recognized.

A Risk Index for Geriatric Acute Medical Admissions (RIGAMA). Acute Med 2014; 13:6-11. [PMID: 24616899] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 06/03/2023]
Abstract
AIM to create and validate a Risk Index for Geriatric Acute Medical Admissions (RIGAMA) for those aged ≥ 65, based on accumulation of deficits. METHODS we retrospectively validated a 30-item RIGAMA against inpatient mortality, length of stay (LOS), discharge to long-term care (LTC) and 30-day readmission, adjusted for age. RESULTS ≥ 1 RIGAMA deficit was superior to age in predicting mortality and prolonged LOS, with a clear incremental effect. The latter was true for ≥3 deficits in predicting 30-day readmission. Three to 5 deficits predicted discharge to LTC better than age. CONCLUSIONS RIGAMA is easy to collect by the admitting junior doctor and may help trigger early senior support and inform the appropriate use of hospital resources by older patients.

Abstract
BACKGROUND Following an emergency medical admission, patients may be admitted an acute medical assessment unit (AMAU) or directly into a ward. An AMAU provides a structured environment for their initial assessment and treatment. METHODS All emergency admissions (66,933 episodes in 36,271 patients) to an Irish hospital over an 12-year period (2002-2013) were studied with 30-day in-hospital mortality as the outcome measure. Univariate Odds Ratios, by initial patient allocation, and the fully adjusted Odds Ratios were calculated, using a validated logistic regression model. RESULTS Patients, by design, were intended to be admitted initially to the AMAU (<= 5 day stay). Capacity constraints dictated that only 39.8% of patients were so admitted; the remainder bypassed the AMAU to a ward (60.2%). All patients remained under the care of the admitting consultant/team. We computed the risk profile for each group, using a multiple variable validated model of 30-day in-hospital mortality; the model indicated the same risk profile between these groups. The univariate OR of an in-hospital death by day 30 for a patient initially allocated to the AMAU, compared with an initial ward allocation was 0.76 (95% CI: 0.71, 0.82- p<0.001). The fully adjusted risk for patients was 0.67 (95% CI: 0.62, 0.73- p<0.001). CONCLUSION Patients, with equivalent mortality risk, allocated initially to AMAU or a more traditional ward, appeared to have substantially different outcomes.

Abstract
BACKGROUND There is interest in emergency medical admissions, the outcomes of major reconfigurations and the development of systems and processes for Acute Medicine. We report on the long-term outcomes of an Acute Medical Admissions Unit, using a database of emergency admissions to St James' Hospital, Dublin, from 2002 to 2012. METHODS All emergency admissions (67,971 episodes in 37,828 patients) were tracked and in-hospital mortality, length of stay and emergency 'wait' numbers and times summarized. We examined outcomes using generalized estimating equations, an extension of generalized linear models that permitted adjustment for correlated observations (readmissions). Margins statistics used adjusted predictions to test for interactions of key predictors while controlling for other variables using computations of the average marginal effect. RESULTS By episode, the in-hospital mortality averaged 5.8% (95% CI 5.6-5.9%); the relative risk reduction (RRR) was 35.0% between 2002 and 2012, from 7.0% to 4.6% (P = 0.001), with a number needed to treat (NNT) of 40.7. By unique patient the in-hospital mortality averaged 10.3% (95% CI 10.0-10.6%) with a RRR of 60.0% from 14.5% to 5.7% (P = 0.001), with an NNT of 11.4. Emergency Department 'wait' numbers decreased by 43%. The main mortality outcome predictors were Illness Severity, Charlson Comorbidity, Manchester Triage Category, O2 saturation, blood culture results, transfusion requirement and a primary respiratory or neurological diagnosis; the model had a high AUROC of 0.88 (95% CI 0.87, 0.88). CONCLUSION Institution reform can result in substantial outcome and process measure benefits, improving care delivery to emergency medical admissions.

Abstract
The objective of this study was to assess appropriate thromboprophylaxis prescription rates in a university hospital and to re-audit after a series of interventions. The notes of all acute medical patient admissions over a 4-week period were assessed for VTE risk factors and prescription of thromboprophylaxis. Subsequently, a series of hospital wide interventions including educational initiatives and a new drug prescription chart were introduced. 2 years post intervention the audit was repeated. Pre-intervention, 104 of 265 (39%) "at risk" patients were prescribed appropriate thromboprophylaxis. Post intervention the prescription rate increased to 108 of 188 (57%) "at risk patients". The results of the pre- intervention audit are consistent with the published literature. While there was a significant increase in prescription rates post intervention, over 40% of "at risk" patients still did not receive thromboprophylaxis highlighting the challenge in attempting to close the gap between guidelines and actual practice.

Abstract
BACKGROUND Increasing hospital or specialist volumes has been shown to improve outcomes; there are little data on volumes and outcomes in emergency medical admissions. We have examined the hospital length of stay (LOS) and 30-day mortality for patients admitted under a consultant 'of the day' having high- or low-admission volumes. METHODS An analysis was performed on all emergency medical patients admitted between 1 January 2002 and 31 December 2011, using anonymous patient data. We calculated the numbers of unique patients admitted to each 'on call' consultant and allocated the latter to a high- (70th centile with 8/22 consultants) or low-volume (14/22 consultants) category. We examined outcomes (LOS and in-hospital 30-day mortality), by these cut-offs employing logistic regression to calculate unadjusted and adjusted odds ratios (ORs) and 95% confidence intervals (CIs). RESULTS The hospital LOS was shorter (P < 0.001) for high [median 4.2, inter-quartile range (IQR) 1.7, 8.7] compared with the lower volume group (median 4.8, IQR 1.9, 9.7). There was a reduced 30-day in hospital mortality for high-volume (8.2%) compared with low-volume consultants (9.6%: P < 0.01). An admission under a high-volume consultant was independently predictive of survival, after adjustment for other outcome predictors including co-morbidity; the relative risk reduction was 25% [OR 0.75 (95% CI 0.68-0.82): P < 0.001]. CONCLUSION In an era of increasing specialization, these data provide support for the concept that the frequency of being 'on-call' contributes to maintaining competence with an associated improvement in patient outcomes.

Abstract
BACKGROUND Deprivation in the general population predicts mortality. We have investigated its relevance to an acute medical admission, using a database of all emergency admissions to St James' Hospital, Dublin, over a 10-year period (2002-11). METHODS All emergency admissions, based on geocoding of residence, were allocated to a Small Area Health Research Unit division, with a corresponding deprivation index. We then examined this index as a univariate (unadjusted) and independent (adjusted) predictor of 30-day in-hospital mortality. RESULTS The 30-day in-hospital mortality, over the 10-year period, was higher for those in the upper half of the deprivation distribution (9.6 vs. 8.6%; P = 0.002). Indeed, there was a stepwise increase in 30-day mortality over the quintiles of deprivation from 7.3% (Quintile 1) to 8.8, 10.0, 10.0 and 9.3%, respectively. Univariate logistic regression of the deprivation indices (quintiles) against outcome showed an increased risk (P = 0.002) of a 30-day death with odds ratios (ORs), respectively (compared with lowest deprivation quintile) of 1.39 [95% confidence intervals (CI) 1.21, 1.58], 1.47 (95% CI 1.29, 1.68), 1.44 (95% CI 1.26, 1.64) and 1.39 (95% CI 1.22, 1.59). The deprivation index was an independent predictor of outcome in a model when adjusted for illness severity and co-morbidity. The fully adjusted OR for a 30-day death was increased by 31% (P = 0.001) for patients in the upper half of the deprivation index distribution (OR 1.35; 95% CI 1.23, 1.48; P < 0.001). CONCLUSION Deprivation, independent of co-morbidity or acute illness severity, is an independent predictor of 30-day mortality in acute medical admissions.

Abstract
AIM The role of laparoscopic surgery in the management of patients with diverticular disease is still not universally accepted. The aim of our study was to evaluate the results of laparoscopic surgery for diverticular disease in a centre with a specialist interest in minimally invasive surgery. METHOD All diverticular resections carried out between 2006 and 2010 were reviewed. Data recorded included baseline demographics, indication for surgery, operative details, length of hospital stay and complications. Complicated diverticular disease was defined as diverticulitis with associated abscess, phlegmon, fistula, stricture, obstruction, bleeding or perforation. RESULTS One hundred and two patients (58 men) who had surgery for diverticular disease were identified (median age 59 years, range 49-70 years). Sixty-four patients (64%) had surgery for complicated diverticular disease. The indications were recurrent acute diverticulitis (37%), colovesical fistula (21%), stricture formation (17%) and colonic perforation (16%). Sixty-nine cases (88%) were completed by elective laparoscopy. Postoperative mortality was 0%. For elective cases there was no difference in morbidity rates between patients with complicated and uncomplicated diverticular disease. The overall anastomotic leakage rate was 1% and the wound infection rate 7%. There was a nonsignificant trend to higher conversion to open surgery in the elective group in complicated (11.4%) compared with uncomplicated patients (5.2%) (P=0.67). Electively, the rate of stoma formation was higher in the complicated (31.6%) than the uncomplicated group (5.2%) (P<0.02). CONCLUSION Laparoscopic surgery for both complicated and uncomplicated diverticular disease is associated with low rates of postoperative morbidity and relatively low conversion rates. Laparoscopic surgery is now the standard of care for complicated and uncomplicated diverticular disease in our institution.

The bothersomeness of patient self-rated "complications" reported 1 year after spine surgery. EUROPEAN SPINE JOURNAL : OFFICIAL PUBLICATION OF THE EUROPEAN SPINE SOCIETY, THE EUROPEAN SPINAL DEFORMITY SOCIETY, AND THE EUROPEAN SECTION OF THE CERVICAL SPINE RESEARCH SOCIETY 2012; 21:1625-32.

Abstract
PURPOSE The last few decades have witnessed a paradigm shift in the assessment of outcome in spine surgery, with patient-centred questionnaires superseding traditional surgeon-based assessments. The assessment of complications after surgery and their impact on the patient has not enjoyed this same enlightened approach. This study sought to quantify the incidence and bothersomeness of patient-rated complications 1 year after surgery. METHODS Patients with lumbar degenerative disorders, operated with the goal of pain relief between October 2006 and September 2010, completed a questionnaire 1 year postoperatively enquiring about complications arising as a consequence of their operation. They rated the bothersomeness of any such complications on a 5-point scale. Global outcome of surgery and satisfaction at the 12-month follow-up were also rated on 5-point Likert scales. The multidimensional Core Outcome Measures Index (COMI) was completed preoperatively and at the 12-month follow-up. RESULTS Of 2,282 patients completing the questionnaire (92% completion rate), 687 (30.1%) reported complications, most commonly sensory disturbances (36% of those with complications) or ongoing/new pain (26%), followed by motor problems (8%), pain plus neurological disturbances (11%), and problems with wound healing (6%). The corresponding "bothersomeness" ratings for these were: 1% not at all, 23% slightly, 27% moderately, 31% very, and 18% extremely bothersome. The greater the bothersomeness, the worse the global outcome (Rho = 0.51, p < 0.0001), patient satisfaction (Rho = 0.44, p < 0.0001) and change in COMI score (Rho = 0.52, p < 0.0001). CONCLUSION Most complications reported by the patient are perceived to be at least moderately bothersome and hence are not inconsequential. Complications and their severity should be assessed from both the patient's and the surgeon's perspectives--not least to better understand the reasons for poor outcome and dissatisfaction with treatment.

Abstract
BACKGROUND The utility of risk stratification following an emergency medical admission has been debated. We have examined the predictability of outcomes, from a database of all emergency admissions to St James' Hospital, Dublin, over a six year period (2005-2010). METHODS Analysis was performed using the hospital in-patient enquiry system, linked to the patient administration system and laboratory data. The utility of a fractional polynomial laboratory only model to predict 30-day in-hospital mortality was determined. RESULTS The AUROC for the laboratory parameters to predict a 30 day death was 0.90 ( 95% CI 0.89, 0.90) in the 2002 - 2010 derivation dataset and was 0.88 (95% CI 0.86, 0.90) in the 2011 validation set. The addition of co-morbidity measures did not improve the model prediction (0.89 : 95% CI 0.88 - 0.89). CONCLUSION A fractional polynomial laboratory only model can reliably predict 30-day hospital mortality following an emergency medical admission, potentially allowing resources to be risk focused and patients to be prioritised.

Abstract
AIM to describe the characteristics and outcomes of homeless people admitted to our Internal Medicine service in St. James's Hospital, Dublin (Ireland), between 2002 and 2011. METHODS we interrogated an anonymized in-patient database. RESULTS there were 1,460 homeless admissions (623 unique patients; 39% admitted more than once). Most patients were young, male, and had low comorbidity levels. Thirty-seven percent of the admissions were alcohol-related and 27% substance abuse-related. Thirteen percent had an active psychiatric illness. Their in-patient mortality rate was 5%. Seventy-two percent were discharged without the residential arrangement being explicitly documented, 15% self-discharged or absconded, and 8% were discharged to a residential facility. CONCLUSION results are novel in our context and will be relevant for local policy and practice.

Abstract
Effective chronic disease management (CDM) requires the ready availability and communication of accurate, clinical disease specific information. Using epilepsy as a probe into CDM, we report on the availability and reliability of clinical information in the primary care records of people with epilepsy (PWE). The medical records of 374 PWE from 53 general practices in the Mid-West region of Ireland were examined. Confirmation of an epilepsy diagnosis by a neurologist was documented for 132 (35%) patients. 282 (75%) patients had no documented evidence of receiving specialist neurology review while 149 (40%) had not been reviewed by their GP in the previous two years for their epilepsy. Significant variation in documentation of epilepsy specific information together with an inadequacy and inconsistency of existing epilepsy services was highlighted.

Abstract
BACKGROUND A weekend emergency medical admission has been associated with a higher mortality. We have examined all weekend admissions to St James' Hospital, Dublin between 2002 and 2009. METHODS We divided admissions by weekday or weekend (Saturday or Sunday) presentation. We utilised a multivariate logistic model, to determine whether a weekend admission was independently predictive of 30 day outcome. RESULTS There were 49337 episodes recorded in 25883 patients; 30-day inhospital mortality at the weekend (9.9% vs. 9.0%) had an unadjusted Odds Ratio of 1.11 (95% CI 0.99, 1.23: p=0.057). In the full risk unlike the univariate) model, a weekend admission was not independently predictive (OR 1.05; 95% CI: 0.88, 1.24). The case-mix for a weekend admission differed; with more neurological diagnoses (22.8% vs 20.4% : p = 0.001) and less gastrointestinal disease (18.3% vs 21.1% : p = 0.001). A biochemistry only illness severity score predicted a higher mortality for weekend admissions. CONCLUSION Patients admitted at the weekend had an approximate 11% increased 30-day in-hospital mortality, compared with a weekday admission. However, admission at the weekend was not independently predictive in a risk model that included Illness Severity (age and biochemical markers) and co-morbidity. Sicker patients, with a worse outcome, are admitted over the weekend; these considerations should inform the allocation of healthcare resources.

Abstract
AIM To develop and validate an in-hospital mortality risk prediction tool for unselected acutely ill medical patients using routinely collected physiological and laboratory data. DESIGN Analysis of all emergency medical patients admitted to St James's Hospital (SJH), Dublin, between 1 January 2002 and 31 December 2007. Validation using a dataset of acute medical admissions from Nenagh Hospital 2000-04. METHODS Using routinely collected vital signs and laboratory findings, a composite 5-day in-hospital mortality risk score, designated medical admissions risk system (MARS), was developed using an iterative approach involving logistic regression and multivariable fractional polynomials. Results are presented as area under receiver operating characteristics curves (AUROC) as well as Hosmer and Lemeshow goodness-of-fit statistics. RESULTS A total of 10 712 and 3597 unique patients were admitted to SJH and Nenagh Hospital, respectively. The final score included nine variables [age, heart rate, mean arterial pressure, respiratory rate, temperature, urea, potassium (K), haematocrit and white cell count]. The AUROC for 5-day in-hospital mortality was 0.93 [95% confidence interval (CI) 0.92-0.94] for the SJH cohort (Hosmer and Lemeshow test, P = 0.32) and 0.92 (95% CI 0.90-0.94) for the external Nenagh hospital validation cohort (Hosmer and Lemeshow test, P = 0.28). CONCLUSION In-hospital mortality estimation using only routinely collected emergency department admission data is possible in unselected acute medical patients using the MARS system. Such a score applied to acute medical patients at the time of admission, could assist senior clinical decision makers in promptly and accurately focusing limited clinical resources. Further studies validating the impact of this model on clinical outcomes are warranted.

Abstract
BACKGROUND Serum sodium has been shown to predict mortality in heart and liver failure. AIM To determine whether serum sodium independently predicts in-hospital mortality during any emergency medical admission. DESIGN An analysis was performed of all emergency medical patients admitted to St James's Hospital (SJH), Dublin between 1 January 2002 and 31 December 2006, using the hospital inpatient enquiry (HIPE) system, linked to the patient administration system and laboratory datasets. Hospital mortality was obtained from a database of 20 deaths occurring during the same period under physicians participating in the 'on call' roster. METHODS The serum sodium was determined at admission in all cases where it was deemed clinically necessary. Logistic regression was used to calculate crude and 25 adjusted odds ratios (ORs). Factors adjusted for included age, illness severity score (Modified Apache II score), major disease category, ICU stay, year effect, blood transfusion, gender and sepsis. RESULTS A total of 14 239 patients (47.5% male) were included in the analysis. Mortality had a U-shaped distribution and was highest in patients whose sodium level was <125 or >140 mmol/l. The unadjusted OR of death within 30 days of admission was 3.36 (95% CI 2.59-4.36) and 4.07 (95% CI 2.95-5.63) with sodium level <125 and >140 mmol/l, respectively. Adjustment for all of the factors above reduced the mortality odds in all hyponatraemia groups but all remained significant predictors of mortality. After adjustment for illness severity score the OR ratio for death in the >140 mmol/l group fell to 1.41 (95% CI 0.97-2.07). DISCUSSION The serum sodium is a powerful initial marker of likely mortality in unselected general medical patients. The increased death rate in hyponatraemic patients is independent of other clinical variables, whereas mortality in the hypernatraemic group is primarily a factor of illness severity.

Abstract
Bouveret's syndrome, first described in 1896 by Léon Bouveret, is rare, limited to approximately 200 published case reports to date [Ariche et al.: Scand J Gastroenterol 2000;35:781–783]. It is a subgroup of gallstone ileus in which a cholecystoduodenal fistula allows the passage of a gallstone that obstructs the duodenum, causing gastric outlet obstruction. This case is unique as it describes Bouveret's syndrome in a patient with combined cholecystoduodenocolic fistulae. Gastric outlet obstruction was successfully managed endoscopically with lithotripsy. Both fistulae were subsequently managed conservatively without any complications.

Abstract
AIM To determine the impact of the introduction of an acute medical admission unit (AMAU) on all-cause hospital mortality in unselected patients undergoing acute medical admission to a teaching hospital. DESIGN Analysis of data recorded in the hospital in-patient enquiry (HIPE) system relating to all emergency medical patients admitted to St James's Hospital (SJH), Dublin between 1 January 2002 and 31 December 2006. METHODS The reference year was 2002, during which patients were admitted to a variety of wards under the care of a named consultant physician. In 2003, two centrally located wards were re-configured to function as an AMAU, and all emergency medical patients were admitted to this unit following emergency department evaluation. Hospital mortality was obtained from a database of deaths occurring during this period and linked to HIPE data. RESULTS Following the introduction of the AMAU process, all-cause hospital mortality decreased from 12.6% in 2002 to 7.0% in 2006 (P < 0.0001), representing a 44.4% relative reduction during the course of the 5-year observation period (P < 0.0001). The Odds ratio (95% confidence interval) for all-cause mortality in 2006 compared with 2002 was 0.28 (0.23, 0.35). This effect was powerfully independent of other covariates, including Charlson co-morbidity and illness severity score (APACHE II), in binary logistic regression analysis and was observed across a wide cross-section of diagnostic groups. CONCLUSION The introduction of an AMAU significantly improved all-cause hospital mortality in acute unselected medical patients. The delivery of Acute Medicine may be enhanced by structural reform with emphasis on focus and volume. Prospective studies validating similar models elsewhere should be explored.

Abstract
BACKGROUND Several tools have been used for assessing risk situations and for gathering tackle information from international football matches for men but not for women. PURPOSE To analyse activities in women's football and to identify the characteristics and risk potentials of tackles. STUDY DESIGN Retrospective video analysis. METHOD Video recordings of 24 representative matches from six women's top-level tournaments were analysed for tackle parameters and their risk potential. RESULTS 3531 tackles were recorded. Tackles in which the tackling player came from the side and stayed on her feet accounted for nearly half of all challenges for the ball in which body contact occurred. 2.7% of all tackles were classified as risk situations, with sliding-in tackles from behind and the side having the highest risk potential. Match referees sanctioned sliding-in tackles more often than other tackles (20% v 17%, respectively). Tackle parameters did not change in the duration of a match; however, there was an increase in the number of injury risk situations and foul plays towards the end of each half. CONCLUSIONS Match properties provide valuable information for a better understanding of injury situations in football. Staying on feet and jumping vertically tackle actions leading to injury were sanctioned significantly more times by the referee than those not leading to injury (p<0.001), but no such difference was seen for sliding-in tackles (previously reported to have the highest injury potential in women's football). Therefore, either the laws of the game are not adequate or match referees in women's football are not able to distinguish between sliding-in tackles leading to and those not leading to injury.

Abstract
BACKGROUND Analyses of tackle parameters in injury situations have provided valuable information regarding men's football. However, there are no similar data for women's football. OBJECTIVE To categorise the tackle mechanisms leading to injury in elite women's football. STUDY DESIGN Retrospective video analysis of injury situations. METHODS Events associated with all reported injuries during six women's top-level tournaments were analysed on video recordings for tackle parameters. RESULTS More than half of all injuries were due to tackles from the side (52%, 103/200), whereas tackles from behind were much less commonly involved in injury situations (11%, 21/200). One-footed (65%, 130/200) and upper body (21%, 42/200) tackle actions were most common. Sliding-in tackles leading to injury were the least likely to be sanctioned by match referees. Tackling players (45%, 90/200) were almost as likely to be injured as the tackled player (55%). CONCLUSION The present study found differences between injury mechanisms in women's football and previously published data on men's football. Further research, especially using video analysis, is needed for a better understanding of risk situations in football.

Abstract
INTRODUCTION Chronic postoperative pain after inguinal hernia repair has an incidence of 0.7-36.7%. This study aimed to look for any relationship between patients presenting with severe pain at initial presentation or a past history of chronic pain conditions and the development of severe chronic pain following inguinal hernia repair. PATIENTS AND METHODS This was a retrospective study in which 24 patients referred to a chronic pain clinic following inguinal hernia repair were compared with 24 age- and sex-matched controls. Hospital notes were reviewed for the severity of presenting pain and a past history of chronic pain. RESULTS Average age was 55.4 years. In the chronic postoperative pain group, 14 (58%) presented with severe pain versus 3 (13%) in the pain-free group. Twelve (50%) of the chronic postoperative pain group had a past history of chronic pain conditions versus none of the pain-free group. Both of these factors showed a significant (P < 0.005) association with severe chronic pain postoperatively. CONCLUSIONS Patients with severe pain at presentation or with a past history of chronic pain conditions are at increased risk of severe chronic pain after inguinal hernia repair. A prospective study is needed to quantify any increased risk, although this would need to be of significant size.

Abstract
OBJECTIVES To determine the impact of reorganisation of an acute admissions process on numbers of people in the emergency department (ED) awaiting admission to a hospital bed in a major teaching hospital. METHODS We studied all emergency medical patients admitted to St James' Hospital, Dublin, between 1 January 2002 and 31 December 2004. In 2002, patients were admitted to a variety of wards from the ED when a hospital bed became available. In 2003, two centrally located wards were reconfigured to function as an acute medical admissions unit (AMAU) (bed capacity 59), and all emergency patients were admitted directly to this unit from the ED (average 15 admissions per day). The maximum permitted length of stay on the AMAU was 5 days. We recorded the number of patients in the ED, who were awaiting the availability of a hospital bed, at 0700 and 1700 on the days of recording during the 36 month study period. RESULTS The impact of the AMAU reduced overall hospital length of stay from 7 days in 2002 to 5 days in 2003 and 2004 (p<0.0001). The median number of patients waiting in the ED for a hospital bed reduced from 14 in 2002 to 9 in 2003 and 8 in 2004 (p<0.0001). While age and sex of patients did not differ over the years, the factors that independently contributed to the number of patients awaiting admission were the day of the week, the month of the year, and and the extent of the comorbidity index on the previous day's intake (p<0.0001). CONCLUSIONS This study found that reorganisation of a system for acute medical admissions can significantly impact on the number of patients awaiting admission to a hospital bed, and allow an ED to operate efficiently and at a level of risk acceptable to patients.

Abstract
OBJECTIVE To find out if there was a difference between hospital consultants, all trained in acute general medicine, in length of stay (LOS), re-admission rates, resource utilisation, and diagnostic coding, among patients admitted as emergencies to St James' Hospital (SJH) Dublin. METHODS A retrospective analysis was performed of data on discharges from hospital, recorded in the hospital in-patient enquiry (HIPE) system, relating to 9204 episodes among 6968 emergency medical patients admitted to SJH between 1 January 2002 and 31 October 2003. For comparative analysis, four physician groups were defined consisting of gastroenterology (GI, n = 4), respiratory (n = 3), general internal medicine (GIM, n = 2), or specialty (n = 5). RESULTS GIM consultants had the shortest LOS (median 5 days); GIM and respiratory consultants were less likely to have long stay patients (> 30 days, p<0.0001). Patients re-admitted under the same consultant had a longer LOS than those re-admitted under a different consultant (p<0.0001). Endoscopy and GI radiology investigations were used most by GI consultants, computed tomography of the thorax by respiratory, ECHO by respiratory and specialty, and computed tomography of brain by GIM and specialty consultants. GI diagnostic codings were more frequent with GI consultants (p<0.0001), respiratory diagnoses and malignancy with respiratory (p<0.0001 for both), diabetes and hypertension with specialty (p = 0.0017), and heart failure more with GIM consultants (p = 0.001). CONCLUSIONS This study found that the HIPE database was very powerful in predicting differences between hospital consultants in LOS, re-admission rates, resource utilisation, and disease coding. It would be of interest to examine the extent to which protocols and guidelines could reduce such variations.
