South Asian ethnicity and risk of childhood accidents: an ecological study at enumeration district level in Leicester

BACKGROUND: Surveys of 'self-reported' accidents suggest that South Asian children in the United Kingdom may have lower rates of childhood accidents, but little is known about their susceptibility to severe accidents compared with white children. METHODS: We conducted an ecological study at the level of Census enumeration districts to compare hospital utilization as a result of childhood accidents according to White, South Asian, Black or 'Other' ethnic grouping and Townsend deprivation score in Leicester. Enumeration districts were assigned to postcoded data for fracture clinic attendances between 1997 and 1999 and in-patient admissions and in-patient stays of longer than 3 days as a result of accidents between 1995 and 1999 in children under 16 years. RESULTS: South Asian children were less likely than white children to attend fracture clinic, be admitted or to have a prolonged stay as a result of an accident. Having adjusted for deprivation score, for a 10 per cent increase in the proportion of South Asian residents in an enumeration district, the odds ratio for an in-patient stay of longer than 3 days was 0.95 (95 per cent confidence interval (CI) 0.91-1.00, p = 0.035), for an accident admission the odds ratio was 0.93 (95 per cent CI 0.92-0.94, p < 0.001) and for attendance at fracture clinic the odds ratio was 0.94 (95 per cent CI 0.92-0.96, p < 0.001). For a district with 70 per cent of its children from South Asian groups (as observed in one-fifth of Leicester's enumeration districts), this represents a 40 per cent lower rate of accident admissions. CONCLUSIONS: South Asian children were significantly less likely to utilize hospital services as a result of an accident. This may well be explained by differential exposure to accident hazards across ethnic groups, rather than by different thresholds of hospital attendance, given that hospital utilization was also lower for serious accidents in South Asian children.     

The impact of utilization management on readmissions among patients with cardiovascular disease

OBJECTIVE: To determine if prospective utilization reviews that lead to reduced hospital length of stay (LOS) relative to days requested by an attending physician affect the likelihood of readmission for privately insured patients with cardiovascular disease. DATA SOURCES: Data obtained from a private insurance company on utilization management decisions from 1989 through 1993. During this five-year period, 39,117 inpatient reviews were conducted, 4,326 (11.1 percent) on patients with cardiovascular disease. We selected for analysis all 4,326 reviews performed on patients with cardiovascular disease. STUDY DESIGN: We used proportional hazard analysis (Cox regression) to investigate the relationship between LOS reductions relative to days requested by a patient's attending physician and the likelihood of readmission within 60 days of discharge. Separate analyses were performed for medical and procedural admissions. PRINCIPAL FINDINGS: There were 2,813 requests for medical admission, and 1,513 requests for procedural admission. Requests for admission were rarely denied. Length of stay was reduced relative to that requested by the treating physician for 17 percent and 19 percent of medical and procedural admissions, respectively. Cumulative 60-day readmission rates were 9.5 percent for medical admissions and 12.3 percent for procedural admissions. We found no relationship between LOS reduction and the likelihood of readmission for medical admissions. However, patients admitted for procedures who had their length of stay reduced by two or more days were 2.6 times as likely to be readmitted within 60 days as those who had no reduction in their length of stay (95% CI: 1.3-5.1; p < .005). CONCLUSIONS: Utilization management (UM) rarely denies requests for inpatient treatment of cardiovascular disease. The association between LOS reduction and the likelihood of readmission for patients admitted for cardiovascular procedures raises concern that UM may adversely affect clinical outcome for some patients. Further research is needed to definitively elucidate any relationship that might exist between utilization review decisions and quality of care.     

Variation in hospital use and avoidable patient morbidity

OBJECTIVES: To determine whether geographical areas with relatively low overall hospitalization rates have higher population-based rates of admission of patients with advanced stages of disease. METHODS: Age- and sex-standardized hospital admission rate were calculated for the residents of the 80 Local Health Units in Lombardia, Italy. Using the Disease Staging classification, advanced stage admissions were identified for six common medical and surgical conditions, which it was presumed would reflect untimely hospital admission. Standardized rates of advanced stage admissions were compared in areas with overall high hospitalization rates (high-use areas). RESULTS: Hospitalization at advanced stages of disease in the low-use areas were significantly higher for the six conditions combined (55.9 vs 43.0 per 100,000; P = 0.005), and for external hernia, appendicitis and uterine fibroma, but not for bacterial pneumonia, diverticular disease and peptic ulcer. For the six study conditions combined, residents of overall low-use area were 30% more likely to be admitted with advanced stages of disease. CONCLUSION: Low overall hospitalization rates were found to be associated with greater severity of illness at hospitalization and potentially avoidable morbidity for some conditions. Policies aimed at curbing unnecessary hospital admission should consider preserving access for appropriate treatment.     

Characteristics of Rural and Urban Cadaveric Organ Transplant Donors and Recipients

CONTEXT: Health disparities have been found when comparing rural and urban populations. Purpose: To compare characteristics of rural and urban cadaveric transplant donors and recipients. METHODS: We used deidentified individual-level data on 55,929 cadaveric transplant donor-recipient exchanges between 2000 and 2003 and examined the relative rates of donating and receiving cadaveric transplants for rural compared to urban residents, as defined by ZIP Codes. FINDINGS: When compared to their urban counterparts, rural organ donors were more likely to have died from head trauma, drowning, motor vehicle accidents, or suicide and less likely to have died from cerebrovascular events, cardiac events, or homicide (P < .001 for all). Rural transplant recipients had lower levels of educational attainment and were less likely to have had the transplant financed by private insurance (P < .001 for all). While we found no statistical difference in days wait to organ transplantation, rural residents were more likely to donate than to receive cadaveric organs (P < .001). CONCLUSIONS: The differences in organ donation that we found warrant further exploration.     

Emergency admission of patients to general surgical beds: attitudes of general practitioners, surgical trainees, and consultants in Liverpool, UK.

OBJECTIVES: To determine (a) whether doctors involved in the process of emergency surgical admission could agree about which patients should be admitted, (b) whether there were consistent differences between doctors in different specialty groups, and (c) whether these opinions were greatly influenced by non-clinical factors. DESIGN: Independent assessment of summarised case histories by three "expert" clinicians (two consultant surgeons and one general practitioner (GP)), by a group of 10 GPs, and by a group of 10 junior and senior surgeons. Experts, but not other observers, scored admissions both independently and as a consensus group. Observers indicated for each patient whether they would admit, would not admit, or were unsure. SETTING: An urban general hospital with teaching status. SUBJECTS: Fifty consecutive patients admitted to the general surgical unit as emergencies during 1995. MAIN OUTCOME MEASURES: Proportion of admissions considered unnecessary or uncertain: agreement between observers on these proportions: effect of social and procedural factors on the admission decision. RESULTS: Between 8 and 34% of admissions were considered unnecessary and 20-38% of unclear necessity. Agreement between the groups of clinicians was not good. GPs and consultant surgeons showed the poorest agreement (kappa = 0.08 to 0.25, 4 comparisons), and the GPs scored a higher percentage of admissions as unnecessary (34 v 8-12%). After discussion, the consensus group achieved good to very good agreement (kappa 0.61-0.84). CONCLUSIONS: Different groups of doctors vary widely in their views about the need for emergency surgical admission. Good agreement can be reached by consensus discussion. GPs are less likely than surgeons to consider emergency surgical admission necessary.     

Trends in colorectal cancer care in southern England, 1989-1993: using HES data to inform cancer services reviews

BACKGROUND: This paper describes trends in hospital activity, hospital admissions, and treatments for colorectal cancer on residents of the South Thames regions (population 8 million) between 1989-1993 against the background of the Calman Report on the future of cancer services in England and Wales. METHODS: The analyses are derived from UK hospital data, which are collected as finished consultant episodes (FCEs). These are defined as episodes "where a patient has completed a period of care under a consultant and is either transferred to another consultant or is discharged." Probability matching was used to derive patient-based records, matching FCEs to admissions. A total of 18,542 South Thames residents aged 40-99 were admitted for colorectal cancer between 1 January 1989 and 31 December 1993. Time trends were analysed for procedures, FCEs, admissions, and patient numbers by admission type (ordinary admissions and day case admissions). RESULTS: Between 1989 and 1993 inclusive colorectal cancer admissions doubled (98% increase p (trend) < 0.0001). These admissions were a result of a 6.4-fold increase in day case admissions and a 41% increase in ordinary admissions. The proportion of patients having a day case admission rose from 9% in 1989 to 18% in 1993 (p < 0.0001). Overall, 2894 (16%) patients had a day case admission; 1894 of these (65%) were also admitted as ordinary admissions. The number of FCEs and admissions per patient rose from 1.37 and 1.28 respectively in 1989 to 2.09 and 1.99 respectively in 1993. FCEs were between 5% and 8% higher than admissions over the five years. The number of ordinary (that is, overnight) inpatient admissions per patient rose from 1.23 to 1.41 over the five year period and day case inpatient admissions from 1.25 to 3.45. Chemotherapy accounted for 50% of the rise in day case admissions; colonoscopy and sigmoidoscopy were associated with a further 18%. Fourteen per cent of the increase in ordinary admissions was also because of chemotherapy. CONCLUSION: The monitoring of site specific trends in admission, treatments, and procedures on a population basis should be a core requirement of health authorities to inform needs assessment, resource allocation, and service planning. The rise in admissions and chemotherapy treatments have implications for drug costs, laboratory and inpatient services, monitoring, and clinical audit.

 

     

Ethnic differences in risk markers for heart disease in Bradford and implications for preventive strategies.

OBJECTIVES--To assess and compare the prevalence of established risk markers for ischaemic heart disease in a sample of Asian and non-Asian men and to relate these observations to preventive strategies. SETTING--Two factories in the textile industry in Bradford, West Yorkshire, UK. Subjects--288 male manual workers aged 20 to 65 years. DESIGN--Cross sectional study within one occupational/social class stratum. MEASUREMENTS AND MAIN RESULTS--Age, body mass index, plasma lipids, fibrinogen and serum insulin values, blood pressure, smoking habits, alcohol consumption, and exercise routines were recorded. Plasma total cholesterol concentrations were significantly lower in Asian than non-Asian men (5.3 mmol/l v 5.8 mmol/l respectively, p < 0.0001), as were low density lipoprotein cholesterol concentrations (3.4 mmol/l v 3.7 mmol/l, p = 0.0150), and high density lipoprotein (HDL) cholesterol (1.1 mmol/l v 1.3 mmol/l, p < 0.0001). Hypercholesterolaemia (concentration > 6.5mM) was present in nearly one quarter of non-Asians but less than one eighth of Asian men. Triglyceride values were not significantly higher in Asians. Smoking rates were high in non-Asians (43.8%) and only slightly lower in Asians (39.1%). Asian smokers smoked fewer cigarettes per day on average (9.3 v 16.1, p = 0.0001). Almost a quarter of non-Asian men (23.1%) and 26.6% of Asian men had raised blood pressure. Systolic pressures were higher in non-Asian men (138.3 mmHg v 133.0 mmHg, p = 0.0070), but diastolic pressures showed no ethnic differences. Diabetes was more prevalent in Asian men (10.9% v 4.4% p < 0.05), who also showed higher serum insulin concentrations after glucose loading (22.3 mU/l v 10.2 mU/l, p < 0.0001). Plasma fibrinogen values were higher in non-Asian men (2.9 g/l v 2.6 g/l, p < 0.0001) and these were associated with smoking. Nearly all non-Asians (92.5%) consumed alcohol at some time whereas 62.5% of Asians habitually abstained from alcohol consumption. Among the drinkers, non-Asian men consumed on average, 23.9 units per week and Asian men 18.4 units per week (p = 0.083). The mean body mass index for Asian men was 24.5 kg/m2 which was not significantly different to the mean in non-Asian men (25.2 kg/m2). The frequency of exercise in leisure time was low in both groups with 44.4% of non-Asian and 21.1% of Asian men taking moderate exercise weekly, and even fewer, regular strenuous exercise (16.3% and 8.6% respectively). CONCLUSIONS--The plasma cholesterol and fibrinogen concentrations, prevalence of hypertension, smoking habits, alcohol intakes, and infrequency of exercise in leisure time in these non-Asian men in Bradford were consistent with an increased risk of heart disease. The pattern of risk markers was clearly different in Asian men. Only their lower HDL cholesterol concentrations, marginally higher triglyceride values, higher prevalence of diabetes, and very low frequency of exercise in leisure time would be consistent with a higher risk of heart disease compared with non-Asians. The implications of these observations for heart disease preventive strategies are discussed.     

Prevalence of low albumin, suboptimal energy, and muscle stores in asian dialysis patients.

OBJECTIVE: Investigate the prevalence of low serum albumin levels (<3.2 g/L) and decreased arm muscle area percentiles and arm fat area percentiles in Asian patients compared with non-Asian patients treated with dialysis. DESIGN: Cross-sectional study in which serum albumin and anthropometric measurements were averaged over 6 months, and compared between patients of Asian ethnicity and patients of non-Asian ethnicity. SETTING: Eight outpatient dialysis facilities. SUBJECTS: Ninety-seven Asian and 513 non-Asian patients treated with hemodialysis or peritoneal dialysis. RESULTS: Height, weight, and body mass index were significantly lower in Asians compared with non-Asians (P <.001). Protein catabolic rate was significantly greater in Asian (1.17 +/- 0.29 g/kg) compared with non-Asian (0.97 +/- 0.28 g/kg) women (P <.001). Asian men (3.30 g/dL) and women (3. 26 g/dL) had lower serum albumin compared with non-Asian men (3.35 g/dL; P =.057) and women (3.34 g/dL; P =.040). The proportion of patients with serum albumin <3.2 g/dL was greater for both Asian women (35%) (P <.040) and men (30%) than non-Asian women (25%) and men (20%). After adjusting for important covariates, serum albumin remained significantly different between Asian and non-Asian patients (P <.05). The proportion below the fifth percentile for arm muscle area was significantly greater for both Asian men (54%) and women (19%) compared with non-Asian men (24%) and women (8%). Proportions of Asian and non-Asian women below the 10th and 5th percentile for arm fat area were similar. However, Asian men (54%) had a significantly greater fat depletion than non-Asian men (26%). CONCLUSION: Mean serum albumin was significantly lower in Asian patients on dialysis than in non-Asians. Muscle stores were depleted in Asian men and women compared with non-Asians, and fat stores were depleted in Asian men. Based on this study, Asian dialysis patients would seem to be at higher nutritional risk than non-Asians, particularly Asian men. Further research is needed to assess factors that affect serum albumin and mortality in Asian dialysis patients, and standards need to be developed to further assess anthropometric measurements in this population.     

Hospital admission patterns in adult patients with skin and soft tissue infections: Identification of potentially avoidable hospital admissions through a retrospective database analysis

Background: Despite the substantial hospitalization costs associated with the management of patients with skin and soft tissue infections (SSTIs) in the inpatient setting, there is limited guidance on patients who should be managed in the hospital relative to the outpatient setting. Studies have demonstrated that SSTI patients without major complications or comorbidities can be successfully managed in the outpatient setting. However, there are limited data on current hospital admission patterns for patients with SSTI. Objectives: Given this literature gap, this study described the current hospital admission patterns among adult patients with SSTI using data from a US hospital research database. Methods: To determine the subset of hospitalized SSTI patients who could likely be managed in the outpatient setting (potentially avoidable hospital admissions), the distribution of hospital admissions was categorized by infection severity and Charlson Comorbidity Index (CCI) score. Results: During the study observational period, there were 610,867 medical encounters across 520 hospitals. Of the 610,867, 125,743 (20.6%) were treated as inpatients. Nearly all patients with life-threatening conditions or systemic symptoms or a CCI score of 2 or greater were admitted. Among those with no life-threatening conditions and no systemic symptoms, admission rates exceeded 10 and 30% for patients with a CCI score of zero and 1, respectively. While the admissions rates for these patient populations were low, they accounted for nearly 60% of all admissions (75,255 of 125,743 hospital admissions). On average, patients with CCI score of zero or 1, independent of the presence of systemic symptoms, were treated in the hospital for about 4 days, costing $6000–$7000 on average. Conclusions: Given the cost associated with the management of patients with SSTIs in the inpatient setting, the findings highlight the critical need for healthcare systems to develop well-defined criteria for hospital admission based on presence of comorbid conditions and infection severity.     

Increased risk for cardiovascular mortality in psoriasis inpatients but not in outpatients

We have conducted a historical cohort study to assess cardiovascular mortality among psoriasis patients. Using the Swedish Inpatient Registry, we selected 8991 patients hospitalized for psoriasis at dermatological wards. To represent an outpatient cohort, 19,757 members of the Swedish Psoriasis Association were selected. Mortality from cardiovascular diseases was compared with the general population. We found no increased cardiovascular mortality among outpatients with psoriasis (standardized mortality ratio, SMR 0.94; 95% confidence interval, CI: 0.89-0.99). The overall risk among inpatients admitted at least once was increased by 50% (SMR 1.52; 95% CI: 1.44-1.60). The excess risk increased with increasing number of hospital admissions (p for trend <0.001). Cardiovascular mortality was higher among those admitted at younger ages (p for trend <0.001; SMR 2.62, 95% CI: 1.91-3.49, for patients aged 20 to 39 years at first admission). Young age at first admission appeared to further increase the risk among those who were repeatedly admitted. We conclude that a diagnosis of psoriasis per se does not appear to increase the risk for cardiovascular mortality. Severe psoriasis, however, here measured as repeated admissions, and early age at first admission, is associated with increased risk for cardiovascular death.     

Hospitalized younger: a comparison of a national sample of homeless and housed inpatient veterans

BACKGROUND: Homelessness is associated with high rates of hospitalizations and age-adjusted mortality. Few studies have examined whether homeless people are admitted to the hospital at an earlier age than the general population or for different diagnoses. METHODS: We compared the age at admission and the primary discharge diagnoses in a national sample of 43,868 hospitalized veterans. RESULTS: The difference in median age between homeless and housed inpatients ranged from 10-18 years for medical-surgical diagnoses and 3-4 years for psychiatric and substance abuse diagnoses (p#.005 for all diagnoses). Homeless veterans were more likely to have been admitted for psychiatric and substance abuse diagnoses (79.9%), compared with housed veterans (29.1%). CONCLUSIONS: Substance abuse and psychiatric illness account for the majority of admissions among homeless veterans. Among all diagnostic groups, homeless people were admitted at younger ages. Our findings suggest that homeless people have either a more rapid disease course, leading to earlier morbidity, or lower admission threshholds sufficient to generate hospital admission.     

Criteria for selecting organ donors and recipients

As there is a world-wide shortage of organs for transplantation, the selection of the patients is more defined by the availability of transplantable organs than by the medical condition of the potential recipient. This shortage of cadaveric organs is mainly responsible for the use of living donors. With HLA identical sibling donors the results are better than with cadaveric organs, but the ethical problems are usually underestimated. For the parent-to-child donation, the HLA compatibility is less than what could be achieved with well-matched cadaveric donors. The use of genetically unrelated donors is unacceptable from the ethical as well as from the medical point of view. The short- and long-term risk of donation has been insufficiently documented. The experience with the introduction of an opting-out legislation in Belgium in 1987 demonstrates that the shortage of cadaveric organs can be overcome. Harmonization of the legislation is, however, necessary so as to achieve comparable organ retrieval rates between countries participating in organ-exchange organisations.     

The prevalence of alcohol misuse among acute admissions: current experience and historical comparisons

BACKGROUND: Over the last 25 years there has been a large increase in alcohol related deaths in Scotland. Medical patients who misuse alcohol may have overt alcohol related disease, but may also present with other unrelated illness. AIM: We examined alcohol misuse amongst acute medical admissions to compare this with other similar studies at the same hospital since 1974. PATIENTS AND METHODS: 850 consecutive admissions to the medical receiving unit of Victoria Infirmary were assessed. They were assessed using the modified Michigan Alcohol Screening Test (MAST) and also by a medical consultant. 414 patients also had their blood ethanol levels measured on admission. RESULTS: 18.6% admissions had a MAST greater than 5 and were considered to misuse alcohol (24.8% male and 12.2% female; p < 0.0001). Patients from socio-economic group V and patients presenting with gastro-intestinal haemorrhage or self-poisoning were more likely to misuse alcohol. The sensitivity and specificity of consultant opinion regarding alcohol misuse were 0.55 and 0.97 compared with the MAST. There was an increase in the alcohol misuse amongst women admitted (12.2%) compared to 1977 (5.5%; p = 0.0026) and 1981/2 (6.3%; p = 0.004). CONCLUSION: Alcohol misuse is common amongst acute medical admissions. Since 1979, there has been a particular increase in female medical admissions who misuse alcohol. Medical opinion regarding alcohol misuse lacks sensitivity in identifying at risk individuals compared with a validated.     

Applying the Health Belief Model and an Integrated Behavioral Model to Promote Breast Tissue Donation Among Asian Americans

An important part in the effort to prevent, treat, and cure breast cancer is research done with healthy breast tissue. The Susan G. Komen for the Cure Tissue Bank at Indiana University Simon Cancer Center (KTB) encourages women to donate a small amount of healthy breast tissue and then provides that tissue to researchers studying breast cancer. Although KTB has a large donor base, the volume of tissue samples from Asian women is low despite prior marketing efforts to encourage donation among this population. This study builds on prior work promoting breast cancer screenings among Asian women by applying constructs from the Health Belief Model (HBM) and the Integrated Behavioral Model (IBM) to investigate why Asian-American women are less inclined to donate their healthy breast tissue than non-Asian women and how this population may be motivated to donate in the future. A national online survey (N = 1,317) found Asian women had significantly lower perceived severity, some lower perceived benefits, and higher perceived barriers to tissue donation than non-Asian women under HBM and significantly lower injunctive norms supporting breast tissue donation, lower perceived behavioral control, and lower intentions to donate under IBM. This study also compares and discusses similarities and differences among East, Southeast, and South Asian women on these same constructs.     

The impact of Medicaid managed care on hospitalizations for ambulatory care sensitive conditions

OBJECTIVE: To determine whether Medicaid managed care is associated with lower hospitalization rates for ambulatory care sensitive conditions than Medicaid fee-for-service. We also explored whether there was a differential effect of Medicaid managed care by patient's race or ethnicity on the hospitalization rates for ambulatory care sensitive conditions. DATA SOURCES/STUDY SETTING: Electronic hospital discharge abstracts for all California temporary assistance to needy families (TANF)-eligible Medicaid beneficiaries less than age 65 who were admitted to acute care hospitals in California between 1994 and 1999. STUDY DESIGN: We performed a cross-sectional comparison of average monthly rates of admission for ambulatory care-sensitive conditions among TANF-eligible Medicaid beneficiaries in fee-for-service, voluntary managed care, and mandatory managed care. DATA COLLECTION/EXTRACTION METHODS: We calculated monthly rates of ambulatory care-sensitive condition admission rates by counting admissions for specified conditions in hospital discharge files and dividing the monthly count of admissions by the size of the at-risk population derived from a separate monthly Medicaid eligibility file. We used multivariate Poisson regression to model monthly hospital admission rates for ambulatory care-sensitive conditions as a function of the Medicaid delivery model controlling for admission month, admission year, patient age, sex, race/ethnicity, and county of residence. PRINCIPAL FINDINGS: The adjusted average monthly hospitalization rate for ambulatory care-sensitive conditions per 10,000 was 9.36 in fee-for-service, 6.40 in mandatory managed care, and 5.25 in voluntary managed care (p<.0001 for all pairwise comparisons). The difference in hospitalization rates for ambulatory care sensitive conditions in Medicaid fee-for-service versus managed care was significantly larger for patients from minority groups than for whites. CONCLUSIONS: Selection bias in voluntary Medicaid managed care programs exaggerates the differences between managed care and fee-for-service, but the 33 percent lower rate of hospitalizations for ambulatory care sensitive conditions found in mandatory managed care compared with fee-for-service suggests that Medicaid managed care is associated with a large reduction in hospital utilization, which likely reflects health benefits. The greater effect of Medicaid managed care for minority compared with white beneficiaries is consistent with other findings that suggest that managed care is associated with improvements in access to ambulatory care for those patients who have traditionally faced the greatest barriers to health care.     

Hospital admissions: who is admitted through the emergency department?

This study examines the co-variates that separate patients who presented an emergent condition without a physician referral and were admitted through the hospital emergency department (ED) from their counterparts who were referred by a physician for the treatment of an elective or urgent condition and were admitted through the admissions department. The analysis was based on 295,945 inpatient admissions in 1999 to short-term acute-care hospitals in Oklahoma. Employing hospital admission as the unit of analysis, logistic regression was used to examine the differential likelihood of admission without a physician referral and through the ED of the uninsured, Medicare beneficiaries, Medicaid recipients, African Americans and Native Americans. The results of the logistic regression analysis indicated that Medicaid recipients and the uninsured were more likely than their commercially-insured counterparts to be admitted, without a physician referral, to an acute-care hospital in Oklahoma following an evaluation in the ED. The findings also suggest that African Americans and, to a lesser extent, Native Americans were more likely than their white counterparts to be admitted through the ED without benefit of a physician referral.     

Trends in hospital admissions for fractures of the hip and femur in England, 1989-1990 to 1997-1998

BACKGROUND: Fractures of the hip are a major public health issue. Suggestions of a recent stabilization of age-specific admission rates would have implications for health service planning, thus we investigated this using hospital data. METHOD: Hospital episode statistics for England, 1989-1990 to 1997-1998, were examined for admissions and deaths for fractures of the hip and femur in NHS hospitals in patients aged 45 years and over. RESULTS: Age-standardized admission rates increased by 32 per cent between 1989-1990 and 1997-1998 in men, and by 30 per cent in women. The increase in admission rates was almost entirely confined to the period 1989-1990 to 1991-1992, with very little change after this. The proportion of admissions ending in death during the study period decreased in both men (-35 per cent) and women (-40 per cent) but this change was largely confined to the early years of the study. The number of admissions from hip and femoral fractures in people aged 65 years and over is projected to increase from about 57,300 in 1997-1998 to 69,500 by 2021-2022. CONCLUSIONS: Age-specific rates of admission appear to be stabilizing, which is in contrast to previous trends. The lack of any decrease in hospital admission and mortality rates over the last 5 years is of concern. The management of osteoporosis-induced fractures in hospitals, the prevention and treatment of osteoporosis in primary care and the prevention of falls should be seen as priorities for the NHS to help reduce the burden of disease from osteoporosis in the elderly.     

The impact of presumed consent legislation on cadaveric organ donation: a cross-country study

In the U.S., Great Britain and in many other countries, the gap between the demand and the supply of human organs for transplantation is on the rise, despite the efforts of governments and health agencies to promote donor registration. In some countries of continental Europe, however, cadaveric organ procurement is based on the principle of presumed consent. Under presumed consent legislation, a deceased individual is classified as a potential donor in absence of explicit opposition to donation before death. This article analyzes the impact of presumed consent laws on donation rates. For this purpose, we construct a dataset on organ donation rates and potential factors affecting organ donation for 22 countries over a 10-year period. We find that while differences in other determinants of organ donation explain much of the variation in donation rates, after controlling for those determinants presumed consent legislation has a positive and sizeable effect on organ donation rates. We use the panel structure of our dataset to test and reject the hypothesis that unmeasured determinants of organ donation rates confound our empirical results.     

Management of tuberculosis in a British inner-city population

BACKGROUND: The aim of the study was to investigate the management of patients with tuberculosis (TB) in terms of their utilization of health service resources. METHODS: An analysis of patient records was carried out in an NHS Trust in East London, United Kingdom, serving a socioeconomically deprived population. The subjects were all residents of Tower Hamlets treated for drug-sensitive TB in the in-patient and out-patient departments of the Trust in 1998. RESULTS: Of the 62 patients with TB studied, 38 (61 per cent) had an in-patient stay at some stage of their management. Twenty-six of these 38 were admitted acutely ill via the Accident and Emergency Department, 16 having self-presented and 10 after urgent referral by their general practitioner. Only four of the total 62 patients were admitted with previously diagnosed disease, and all four had significant complications necessitating admission. Eight patients were admitted electively for investigation, typically being brief admissions for surgical biopsy. Median in-patient stay was 14 days (range 1-144 days), and in six cases we identified potentially remediable delays in diagnosis and initiation of therapy. CONCLUSIONS: UK and US guidelines for TB imply out-patient management as the norm. Our study shows a very high rate of in-patient care, largely a consequence of the emergency admission of acutely ill, previously undiagnosed cases. There are public health implications in terms of spread of infection from individuals with advanced disease. The high utilization of expensive in-patient resources has significant implications for purchasers and providers of care for TB in socio-economically deprived areas. Further, the cost-effectiveness of public health interventions aimed at limiting the spread of TB should be assessed by reference to this true, high cost of managing TB, not a low cost based on false assumptions about rates of out-patient versus in-patient care.
