Poor outcomes among elderly patients hospitalized for influenza-like illness

BACKGROUND AND OBJECTIVE

Global Influenza Hospital Surveillance Network is a worldwide initiative that aims to document the burden of influenza infections among acute admissions and vaccine effectiveness in particular countries. As a partner of this platform, we aimed to determine the frequency of influenza infections among acute admissions with influenza-like illness and the outcomes of enrolled patients during the 2015-2016 influenza season in selected hospitals in Turkey.

PATIENTS AND METHODS

The investigators screened the hospital admission registries, chart review or available records, and screened all patients hospitalized in the previous 24-48 hours or overnight in the predefined wards or emergency room. A total of 1351 patients were screened for enrollment in five tertiary care referral hospitals in Ankara and 774 patients (57.3% of the initial screened population) were eligible for swabbing. All of the eligible patients who consented were swabbed and tested for influenza with real-time polymerase chain reaction (PCR) based methods.

RESULTS

Overall, influenza positivity was detected in 142 patients (18.4%). The predominant influenza strain was A H1N1pdm09. Outcomes were worse among elderly patients, regardless of the presence of the influenza virus. Half of the patients over 65 years of age were admitted to the intensive care unit, while one third required any mode of mechanical ventilation and one fourth died in the hospital in that particular episode.

CONCLUSION

These findings can guide hospitals to plan and prepare for the influenza season. Effective influenza vaccination strategies, particularly aimed at the elderly and adults with chronic diseases, can provide an opportunity for prevention of deaths due to influenza-like illness.

Effects of Air Pollution on Hospital Emergency Room Visits for Respiratory Diseases: Urban-Suburban Differences in Eastern China

A study on the relationships between ambient air pollutants (PM_2.5, SO₂ and NO₂) and hospital emergency room visits (ERVs) for respiratory diseases from 2013 to 2014 was performed in both urban and suburban areas of Jinan, a heavily air-polluted city in Eastern China. This research was analyzed using generalized additive models (GAM) with Poisson regression, which controls for long-time trends, the “day of the week” effect and meteorological parameters. An increase of 10 μg/m³ in PM_2.5, SO₂ and NO₂ corresponded to a 1.4% (95% confidence interval (CI): 0.7%, 2.1%), 1.2% (95% CI: 0.5%, 1.9%), and 2.5% (95%: 0.8%, 4.2%) growth in ERVs for the urban population, respectively, and a 1.5% (95%: 0.4%, 2.6%), 0.8% (95%: −0.7%, 2.3%), and 3.1% (95%: 0.5%, 5.7%) rise in ERVs for the suburban population, respectively. It was found that females were more susceptible than males to air pollution in the urban area when the analysis was stratified by gender, and the reverse result was seen in the suburban area. Our results suggest that the increase in ERVs for respiratory illnesses is linked to the levels of air pollutants in Jinan, and there may be some urban-suburban discrepancies in health outcomes from air pollutant exposure.

[Health status and access to health services by the population of L'Aquila (Abruzzo Region, Italy) six years after the earthquake]

Natural disasters, such as the earthquake that occurred in the province of L'Aquila in central Italy, in 2009, generally increase the demand for healthcare. A survey was conducted to assess perception of health status an d use of health services in a sample of L'Aquila's resident population, five years after the event, and in a comparison population consisting of a sample of the resident population of Avezzano, a town in the same region, not affected by the earthquake. No differences were found in perception of health status between the two populations. Both groups reported difficulties in accessing specialized healthcare and rehabilitation services.

A national study of acute hospital based alcohol health workers

Alcohol health workers (AHWs) have been identified as an effective means of tackling alcohol-related hospital admissions. However, there is no understanding of the national coverage, or the extent and diversity of the services provided by hospital-based AHWs. Using a cross-sectional questionnaire, this is the first study to explore the current provision and remit of AHWs in acute hospitals across England.The data was analysed using SPSS. Significant differences were found with regards to the extent and diversity of AHW provision across England. This research provides a point of comparison for current and future hospital-based AHW provision.Further research is necessary to examine different 'service types', establish effective ways of working, and determine whether sources of funding could and should more accurately reflect the remit of hospital-based AHW roles.

[Inventory of attendance at Dutch emergency departments and self-referrals]

OBJECTIVE

To make an inventory of annual attendance at emergency departments (A&E) in the Netherlands.

DESIGN

Inventorisation study in all Dutch A & E departments.

METHOD

All A& E departments in the Netherlands that were operational for 24 hours a day, 7 days a week in December 2012 were approached (n = 93) and the following data were collected over 2012: the total number of patients, the number of hospital admissions through the A & E department, and the number of self-referrals.

RESULTS

Data were obtained from 96% emergency departments (n = 89) throughout the Netherlands, including all 8 university medical centres and 28 hospitals of the association of tertiary medical teaching hospitals (STZ). In 2012 a total of 1,989,746 people attended the 89 emergency departments. The average percentage of hospital admissions from an A & E department was 32% nationwide (range: 8-54). The average percentage of self-referrals to the emergency departments was 30% nationwide (range: 3-76).

CONCLUSION

The number of attendees at A & E, the admission rate through the A & E department and percentage of self-referrals in 2012 showed a range of variation nationwide. The number of people attending A & E has not increased over the last few years and is low in international terms. On average one-third of people attending A & E were admitted. In contrast with prevailing national beliefs,a minority of attendees at A &E departments were self-referrals.

[Criteria for admitting patients with anorexia nervosa as inpatients to a general hospital; survey among internists]

BACKGROUND

Anorexia nervosa (an) is associated with a number of life-threatening complications. Sometimes there are good reasons for admitting an anorexia nervosa patient to a general hospital for treatment as an inpatient. Therefore, there needs to be optimal collaboration between psychiatrists treating the patient and the medical staff at the general hospital.

AIM

To obtain insight into the admission criteria and other possible factors that play a role in the physician's decision to admit a patient with anorexia nervosa for inpatient treatment in a general hospital.

METHOD

Internists and residents-internal medicine completed a questionnaire about admission criteria and, where applicable, about threshold values for these criteria. The physicians were also asked to judge two case vignettes. In addition, they were questioned about other factors that influenced their views on the admission of patients with anorexia nervosa to a general hospital and about their attitude to this patient-group, their experience of treating patients with anorexia nervosa and their awareness of a need for a guideline. The data were collected at the annual Dutch congress for internists at Maastricht.

RESULTS

In total 78 congress attendees responded to the questionnaire; 47% were internist and 53% were resident-in-training. Agreement was greatest with regard to the following admission criteria (top 5): 1. serum potassium (threshold value <2.5 mmol/l was the criterion selected most); 2. arrhythmia; 3. hypoglycemia; 4. heart rate (threshold value <40 bpm was chosen most); 5. prolonged qt interval on an ECG. According to the two fictitious cases, the reason for admitting a patient with anorexia nervosa with milder symptoms was influenced by 'attitude'. Half of the respondents pointed out that the patient's cooperation plays a role in the decision to admit a patient with an eating disorder.

CONCLUSION

Respondents reached a consensus regarding several admission criteria but the threshold values they gave varied substantially. Attitude towards the patient-group can sometimes influence the decision to admit a patient with anorexia nervosa to a general hospital. Internists and residents-in-training indicated they require detailed, carefully compiled guidelines which take into consideration the expected results and which emphasise the importance of obtaining the patient's cooperation.

Hospital-based, acute care after ambulatory surgery center discharge

BACKGROUND

As a measure of quality, ambulatory surgery centers have begun reporting rates of hospital transfer at discharge. This process, however, may underestimate the acute care needs of patients after care. We conducted this study to determine rates and evaluate variation in hospital transfer and hospital-based, acute care within 7 days among patients discharged from ambulatory surgery centers.

METHODS

Using data from the Healthcare Cost and Utilization Project, we identified adult patients who underwent a medical or operative procedure between July 2008 and September 2009 at ambulatory surgery centers in California, Florida, and Nebraska. The primary outcomes were hospital transfer at the time of discharge and hospital-based, acute care (emergency department visits or hospital admissions) within 7-days expressed as the rate per 1,000 discharges. At the ambulatory surgery center level, rates were adjusted for age, sex, and procedure-mix.

RESULTS

We studied 3,821,670 patients treated at 1,295 ambulatory surgery centers. At discharge, the hospital transfer rate was 1.1 per 1,000 discharges (95% confidence interval 1.1-1.1). Among patients discharged home, the hospital-based, acute care rate was 31.8 per 1,000 discharges (95% confidence interval 31.6-32.0). Across ambulatory surgery centers, there was little variation in adjusted hospital transfer rates (median = 1.0/1,000 discharges [25th-75th percentile = 1.0-2.0]), whereas substantial variation existed in adjusted, hospital-based, acute care rates (28.0/1,000 [21.0-39.0]).

CONCLUSION

Among adult patients undergoing ambulatory care at surgery centers, hospital transfer at time of discharge from the ambulatory care center is a rare event. In contrast, the rate of need for hospital-based, acute care in the first week afterwards is nearly 30-fold greater, varies across centers, and may be a more meaningful measure for discriminating quality.

Does childhood attention-deficit/hyperactivity disorder predict risk-taking and medical illnesses in adulthood?

OBJECTIVE

To test whether children with attention-deficit/hyperactivity disorder (ADHD), free of conduct disorder (CD) in childhood (mean = 8 years), have elevated risk-taking, accidents, and medical illnesses in adulthood (mean = 41 years); whether development of CD influences risk-taking during adulthood; and whether exposure to psychostimulants in childhood predicts cardiovascular disease. We hypothesized positive relationships between childhood ADHD and risky driving (in the past 5 years), risky sex (in the past year), and between risk-taking and medical conditions in adulthood; and that development of CD/antisocial personality (APD) would account for the link between ADHD and risk-taking. We report causes of death.

METHOD

Prospective 33-year follow-up of 135 boys of white ethnicity with ADHD in childhood and without CD (probands), and 136 matched male comparison subjects without ADHD (comparison subjects; mean = 41 years), blindly interviewed by clinicians.

RESULTS

In adulthood, probands had relatively more risky driving, sexually transmitted disease, head injury, and emergency department admissions (p< .05-.01). Groups did not differ on other medical outcomes. Lifetime risk-taking was associated with negative health outcomes (p = .01-.001). Development of CD/APD accounted for the relationship between ADHD and risk-taking. Probands without CD/APD did not differ from comparison subjects in lifetime risky behaviors. Psychostimulant treatment did not predict cardiac illness (p = .55). Probands had more deaths not related to specific medical conditions (p = .01).

CONCLUSIONS

Overall, among children with ADHD, it is those who develop CD/APD who have elevated risky behaviors as adults. Over their lifetime, those who did not develop CD/APD did not differ from comparison subjects in risk-taking behaviors. Findings also provide support for long-term safety of early psychostimulant treatment.

What can be learned about the impact of diabetes on hospital admissions from routinely recorded data?

AIM

To determine whether inpatients with diabetes have different lengths of stay, day-case listing rates or emergency readmission rates compared with those without diabetes receiving similar treatment.

METHOD

English 2007-2008 Hospital Episode Statistics were analysed alone and after linkage to the 1.6 million people included in the 2007-2008 English National Diabetes Audit. Length of stay, day-case listing rates and emergency readmission rates were compared between those with and without diabetes by Health Resource Group chapter. Using univariate and multivariate statistics, the potential influences of age, sex, social deprivation, type and complexity of admission were considered.

RESULTS

Of all inpatient spells in Hospital Episode Statistics, 6.2% have diabetes coded at discharge. Substantial under-recording of diabetes has been identified-a further 3% of inpatient spells involve people with diabetes. Inpatients with recorded diabetes stay in hospital for 100% longer on average, are 50% less likely to be treated as day cases and are almost 100% more likely to be readmitted as an emergency. The adverse impact of diabetes on length of stay was similar to that for chronic obstructive pulmonary disease. Most of this adverse effect was in patients coded with diabetes in Hospital Episode Statistics. Multivariate statistical analysis showed that diabetes is independently associated with increased length of stay. The effect differed up to threefold between hospitals.

CONCLUSIONS

Diabetes has an independent adverse effect on key aspects of hospital inpatient stays. If the lowest levels of adverse impact on inpatients with diabetes were more common, substantial cost savings and improved experience of care would be realized.

Assessing the relationship between admission glucose levels, subsequent length of hospital stay, readmission and mortality

This study aimed to investigate relationships between dysglycaemia and length of hospital stay, short-term mortality and readmission in an unselected population in an acute medical unit (AMU). The rate of follow up in non-diabetic individuals with hyperglycaemia was also measured. We analysed data from all 1,502 patients admitted through our AMU in February 2010 to assess blood glucose levels on admission, length of stay, 28-day readmissions and mortality, and to determine whether blood glucose > or = 11.1 mmol/l on admission in non-diabetic individuals was followed up. In total, blood glucose was measured on admission for 893 patients. Mean length of stay was 8.8 (standard deviation 11.9) days, for patients with blood glucose < 6.5 mmol/l on admission; 11.3 (13.6) days, for 6.5-7 mmol/l; 10.2 (14.5) days, for 7.1-9 mmol/l; 10.6 (14.9) days, for 9.1-11 mmol/l; 12 (18.4) days, for 11.1-20 mmol/l and 9.1 (11.2) days, for > 20.1 mmol/l. Length of stay for patients with blood glucose > 6.5 mmol/l on admission was significantly longer (p = 0.002). The 28-day readmission rates were 6.4%, 6%, 9.7%, 12.5%, 10% and 15%, respectively, and 28-day death rates were 4.8%, 6%, 5.8%, 17.2%, 17.1% and 6.1%, respectively. Overall, 51.4% of non-diabetic individuals with blood glucose > 11.1 mmol/l on admission were followed up. The study showed that blood glucose > 6.5 mmol/l on admission is associated with significantly longer length of stay. Hyperglycaemia was associated with increased 28-day mortality and readmissions, and is frequently underinvestigated.

Simple prescribing errors and allergy documentation in medical hospital admissions in Australia and New Zealand

This study aimed to quantify and compare the prevalence of simple prescribing errors made by clinicians in the first 24 hours of a general medical patient's hospital admission. Four public or private acute care hospitals across Australia and New Zealand each audited 200 patients' drug charts. Patient demographics, pharmacist review and pre-defined prescribing errors were recorded. At least one simple error was present on the medication charts of 672/715 patients, with a linear relationship between the number of medications prescribed and the number of errors (r = 0.571, p < 0.001). The four sites differed significantly in the prevalence of different types of simple prescribing errors. Pharmacists were more likely to review patients aged > or = 75 years (39.9% vs 26.0%; p < 0.001) and those with more than 10 drug prescriptions (39.4% vs 25.7%; p < 0.001). Patients reviewed by a pharmacist were less likely to have inadequate documentation of allergies (13.5% vs 29.4%, p < 0.001). Simple prescribing errors are common, although their nature differs from site to site. Clinical pharmacists target patients with the most complex health situations, and their involvement leads to improved documentation.

Patients admitted with an acute coronary syndrome (ACS) in New Zealand in 2007: results of a second comprehensive nationwide audit and a comparison with the first audit from 2002

AIMS

To audit all patients admitted to a New Zealand (NZ) Hospital with an acute coronary syndrome (ACS) over a 14-day period, to assess their number, presentation type and patient management during the hospital admission and at discharge. To compare patient management in 2007 with the 1st NZ Cardiac Society ACS Audit from 2002.

METHODS

We updated the established NZ ACS Audit group of 36 hospitals to 39 hospitals now admitting ACS patients across New Zealand. A comprehensive data form was used to record individual patient information for all patients admitted between 00.00 hours on 14 May 2007 to 24.00 hours on 27 May 2007.

RESULTS

1003 patients, 9% more than in 2002 (n=930), were admitted with a suspected or definite ACS: 8% with a ST-segment-elevation myocardial infarction (STEMI), 41% with a non-STEMI (NSTEMI), 33% with unstable angina pectoris (UAP), and 17% with another cardiac or medical condition. In 2007 non-invasive risk stratification following presentation remained similar to 2002 and was suboptimal: exercise treadmill tests (21% vs 20%, p=0.62), echocardiograms (19% vs 20%, p=0.85). An increase in utilisation of coronary angiography was noted (32% vs 21%, p<0.0001). In hospital revascularisation rates remained low in patients with diagnosed ACS (n=828): STEMI (45%), NSTEMI (23%) and UAP (7.3%). In comparison to 2002, changes were noted in revascularisation techniques with percutaneous coronary intervention (PCI) performed in 19% vs 7% (p<0.0001). The use of coronary artery bypass grafting (CABG) remained extremely low: 2.8% vs 3.5% (p=0.20). The use of hospital and discharge medication of proven benefit was also limited.

CONCLUSIONS

A collaborative group of clinicians and nurses has performed a second nationwide audit of ACS patients. Despite a small increase in access to cardiac angiography, guideline recommended risk stratification following the index suspected ACS admission with a treadmill test or cardiac angiogram occurred in only 1 in 2 (48%) patients. Furthermore, in patients with a definite ACS, levels of revascularisation are low. (PCI 19%, CABG 2.8%). These aspects of care remain of significant concern and have not substantially changed in 5 years. There remains an urgent need to develop a comprehensive national strategy to improve all aspects of ACS patient management.

[An evaluation of the pediatric medico-legal admissions to a tertiary hospital emergency department]

BACKGROUND

This study aimed to determine the demographic and epidemiological characteristics and to investigate the outcomes of pediatric medico-legal cases who admitted to the emergency department. It was also aimed to contribute to the national survey.

METHODS

Medico-legal charts of the pediatric cases were reviewed retrospectively. Patients were allocated into two groups as traumatic (Group 1) and non-traumatic (Group 2). Age, sex, presenting complaint and frequencies, local or multiple trauma frequencies, and localizations (based on the Abbreviated Injury Scale) and also admission, discharge and mortality rates were ascertained. Data were evaluated by descriptive methods, Kolmogorov-Smirnov and chi-square tests. Values of p<0.05 were accepted as significant.

RESULTS

There were a total of 486 eligible patients. The mean age was 8.91+/-5.08 years (95% confidence interval [CI]). The majority (66.3%) were male. The group aged 5-9 years was larger (33.3%) than the others (in Kolmogorov-Smirnov test, p=0.000). Summer was the most common season for admissions. There were 153 patients in Group 1, and the most common complaint was accidental drug intake (13.8%). In Group 2, the most common reason for admission was motor vehicle accident (32.5%).

CONCLUSION

Motor vehicle and home accidents in childhood are preventable health problems. To ensure a safe environment, continuous health education programs on injury and prevention for parents and children and legal controls will be effective in injury control.

Trends in lower extremity amputations in people with and without diabetes in England, 1996-2005

AIMS

To examine trends in non-traumatic lower extremity amputations over a 10-year-period in people with and without diabetes (DM) in England.

METHODS

All individuals admitted to NHS hospitals for non-traumatic amputations between 1996 and 2005 in England were identified using hospital activity data. Postoperative and 1-year mortality were examined between 2000 and 2004.

RESULTS

There was a reduction in minor and major amputations during the study period. The number of type 1 DM- and non-DM-related minor amputations decreased by 11.4% and 32.4%, respectively, while the number of type 2 DM-related minor amputations almost doubled. The incidence of type 1- and non-DM-related minor amputations decreased from 1.5 to 1.2 and from 8.1 to 5.1/100,000 population, respectively, while type 2 DM-related amputations increased from 2.4 to 4.1/100,000 population. The number of type 1- and non-DM-related major amputations declined by 41% and 22%, respectively, whereas type 2 DM-related amputations increased by 43%. The incidence of type 2 DM-related amputations increased from 2.0 to 2.7/100,000 population. Overall perioperative and 1-year mortality did not significantly change between 2000 and 2004.

CONCLUSIONS

While several factors may explain the increase in type 2 DM-related LEAs, these findings highlight the importance of diabetes prevention strategies and controlling risk factors for LEAs in people with diabetes.

Admitting service and morbidity and mortality in elderly patients after hip fracture: finding a threshold for medical versus orthopedic admission

Outcomes by admitting service of 355 consecutive patients admitted for hip fracture at an academic medical center were retrospectively studied. An adverse event occurred in 53 patients (14.9%): 10 in-hospital deaths, 37 intensive care unit transfers, and 25 deaths within 30 days. No significant difference was found between percentages of patients with adverse events admitted to a medical service versus an orthopedic service (52.8% vs 47.2%; P = .8). Criteria that determine admitting service based on medical acuity do not adequately allocate patients at risk for serious morbidity and early mortality to a medical service. Addition of American Society of Anesthesiologists grade 4 and men 85 or older to existing criteria would increase the percentage of patients with adverse events admitted to a medical service (72% vs 28%; P<.005).

[Risk factors for suicide attempts in dual diagnosis patients]

BACKGROUND

Patients suffering from both psychiatric disorders and substance abuse/addiction are titled "dual diagnosis patients" (DDP). Substance abuse/addiction is associated with suicidal behavior. Although our knowledge of substance abuse/addiction and suicide behavior is increasing, we lack sufficient knowledge of suicide among DDP.

OBJECTIVES

(1) To compare the rate of suicide attempts among DDP and non-DDP; (2) To determine risk factors for suicide attempts in DDP.

METHODS

Analysis of 3,433 consecutive admissions: men and women aged 18-65 years in our center (06/2003-06/2005).

RESULTS

Of 848 DDPs' admissions, 197 (23.2%) were after suicide attempts, whereas 403 of 2558 non-DDP's admissions (15.8%) were after suicide attempts (odds ratio [OR] = 1.6; 95% confidence interval [95% CI] = 1.3 - 1.9). The OR in the multiple analysis was 1.4 [95% CI] = 1.1 - 1.8). By multivariate regression analysis, the positive result for Tetrahydrocannabinol (THC) in the urine analysis was a protective factor and a diagnosis of disorders of adult personality and behavior (according to the International Classification of Disease - 10 edition [ICD-10]) was an independent risk factor for suicide attempts.

CONCLUSIONS

DDP have greater risks of suicide attempts than non-DDP. A comprehensive plan of preventive interventions for multidisciplinary staff is recommended in order to reduce suicide rates in DDP.

STOPP (Screening Tool of Older Persons' potentially inappropriate Prescriptions): application to acutely ill elderly patients and comparison with Beers' criteria

INTRODUCTION

STOPP (Screening Tool of Older Persons' potentially inappropriate Prescriptions) is a new, systems-defined medicine review tool. We compared the performance of STOPP to that of established Beers' criteria in detecting potentially inappropriate medicines (PIMs) and related adverse drug events (ADEs) in older patients presenting for hospital admission.

METHODS

we prospectively studied 715 consecutive acute admissions to a university teaching hospital. Diagnoses, reason for admission and concurrent medications were recorded. STOPP and Beers' criteria were applied. PIMs with clear causal connection or contribution to the principal reason for admission were determined.

RESULTS

median patient age (interquartile range) was 77 (72-82) years. Median number of prescription medicines was 6 (range 0-21). STOPP identified 336 PIMs affecting 247 patients (35%), of whom one-third (n = 82) presented with an associated ADE. Beers' criteria identified 226 PIMs affecting 177 patients (25%), of whom 43 presented with an associated ADE. STOPP-related PIMs contributed to 11.5% of all admissions. Beers' criteria-related PIMs contributed to significantly fewer admissions (6%).

CONCLUSION

STOPP criteria identified a significantly higher proportion of patients requiring hospitalisation as a result of PIM-related adverse events than Beers' criteria. This finding has significant implications for hospital geriatric practice.

Weekends: a dangerous time for having a stroke?

BACKGROUND AND PURPOSE

Weekend admissions are associated with higher in-hospital mortality. However, limited information is available concerning the "weekend effect" on stroke mortality. Our aim was to evaluate the impact of weekend admissions on stroke mortality in different settings.

METHODS

We analyzed all hospital admissions for ischemic stroke from April 2003 to March 2004 through the Hospital Morbidity Database. The Hospital Morbidity Database is a national database that contains patient-level sociodemographic, diagnostic, procedural, and administrative information including all acute care facilities across Canada. The major inclusion criterion was admission to an acute care facility with a principal diagnosis of ischemic stroke. Clinical variables and facility characteristics were included in the analysis.

RESULTS

Overall, 26,676 patients were admitted to 606 hospitals for ischemic stroke. Weekend admissions comprised 6629 (24.8%) of all admissions. Seven-day stroke mortality was 7.6%. Weekend admissions were associated with a higher stroke mortality than weekday admissions (8.5% vs 7.4%; odds ratio, 1.17; 95% CI, 1.06 to 1.29). Mortality was similarly affected among patients admitted to rural versus urban hospitals or when the most responsible physician was a general practitioner versus specialist. In the multivariable analysis, weekend admissions were associated with higher early mortality (odds ratio, 1.14; 95% CI, 1.02 to 1.26) after adjusting for age, sex, comorbidities, and medical complications.

CONCLUSIONS

Stroke patients admitted on weekends had a higher risk-adjusted mortality than did patients admitted on weekdays. Disparities in resources, expertise, and healthcare providers working during weekends may explain the observed differences in weekend mortality.

The key to improving prognosis for aneurysmal subarachnoid hemorrhage remains in the pre-hospitalization period

BACKGROUND

Despite advances in neurosurgical management, aneurismal subarachnoid hemorrhage (aSAH) still has high mortality and morbidity. This study aimed to clarify how delaying hospital admission after aSAH contributes to worse prognosis even today and to find the possibility for an improvement of its prognosis by early admission.

METHODS

Four hundred twenty-one consecutive patients are the basis for this study. Cause of delay was classified into 5 categories: patient delay (PD), doctor delay (DD), transportation delay (TD), no delay (ND) (within 2 hours of onset), and others. Condition of each patient was assessed at time of onset and admission using H&K. The relationships between cause of delay and worsening of Hunt and Kosnik grading (H&K) were examined.

RESULTS

The median delay time was 1.7 days. Only 41% of patients visited our institution without delay. Admission delay, especially PD and DD, exhibited a significant correlation to worsening of H&K. In addition to nondirect admission, misdiagnosis or delayed diagnosis contributed significantly to worsening of H&K. Incidence of DD has declined in recent years, whereas that of PD has increased. Consequently, no change in total number of delays was found.

CONCLUSIONS

There remains much room for an improvement of prognosis for aSAH by early admission. We need to fully realize this reality and to directly face this problem.

Does caring for displaced specialty unit patients affect the critical care nurse's perceptions of ability and job satisfaction?

Trauma centers are challenged to share beds with a larger hospital population of critical care patients. Often, this means that patients may be shifted between units when beds are not immediately available in the specialty unit that fits their diagnosis. They are admitted to the first intensive care unit bed that becomes available. This practice results in patients with special care needs being cared for by nursing staff who do not perceive themselves as trained to provide those needs. This practice is referred to as displaced specialty unit (DSU) admission. A review of 2-year data from one large trauma center revealed a total of 1072 DSU patients, of whom 50% were medical patients. A questionnaire given to intensive care unit nurses found that caring for DSU patients did affect their perceptions of their ability to care for such patients and affected their sense of job satisfaction. Strategies to improve nurses' comfort level and competency in treating diverse critical care patients were recommended and implemented.

The epidemiology of organophosphate poisoning in urban Zimbabwe from 1995 to 2000

The objective of this study was to examine current organophosphate usage in Zimbabwe. A cross-sectional descriptive study was done to determine the trends in admissions for organophosphate poisonings in an urban Zimbabwe hospital from 1995 to 2000. Variables such as sex, age, season, geographic area, and intent were examined. In 183,569 records, 599 cases of organophosphate poisoning were found. Organophosphate poisonings increased by 320% over the six years. The male and female admissions' rates were similar (48% vs 52%); 82% of the patients were less than 31 years old. Suicide was the predominant reason for poisoning (74%). Of admissions of children under the age of 10, 62% were due to accidental ingestion. Mortality from organophosphate poisonings was 8.3% over the six years. Organophosphate poisoning is increasing rapidly. In the background of this alarming trend is the physical, mental, and social state of a Zimbabwean society wrought with hardships.

The Sheffield experiment: the effects of centralising accident and emergency services in a large urban setting

OBJECTIVES

To assess the effects of centralisation of accident and emergency (A&E) services in a large urban setting. The end points were the quality of patient care judged by time to see a doctor or nurse practitioner, time to admission and the cost of the A&E service as a whole.

METHODS

Sheffield is a large industrial city with a population of 471000. In 1994 Sheffield health authority took a decision to centralise a number of services including the A&E services. This study presents data collected over a three year period before, during and after the centralisation of adult A&E services from two sites to one site and the centralisation of children's A&E services to a separate site. A minor injury unit was also established along with an emergency admissions unit. The study used information from the A&E departments' computer system and routinely available financial data.

RESULTS

There has been a small decrease in the number of new patient attendances using the Sheffield A&E system. Most patients go to the correct department. The numbers of acute admissions through the adult A&E have doubled. Measures of process efficiency show some improvement in times to admission. There has been measurable deterioration in the time to be seen for minor injuries in the A&E departments. This is partly offset by the very good waiting time to be seen in the minor injuries unit. The costs of providing the service within Sheffield have increased.

CONCLUSION

Centralisation of A&E services in Sheffield has led to concentration of the most ill patients in a single adult department and separate paediatric A&E department. Despite a greatly increased number of admissions at the adult site this change has not resulted in increased waiting times for admission because of the transfer of adequate beds to support the changes. There has however been a deterioration in the time to see a clinician, especially in the A&E departments. The waiting times at the minor injury unit are very short.

[Measurement of care time in patients with acute myocardial infarction admitted to a general ICU: evaluation and improvement]

Acute myocardial infarction (AMI) requires early and safe nursing care, particularly with respect to initiating and following up thrombolytic treatment, the most effective therapy according to the literature. Time is decisive. Recommended door-to-needle time should not exceed 35 minutes (from patient's arrival to injection of the thrombolytic agent in the ICU). This quality of care study centered on the measurement of four partial times and their sum. These times corresponded to different phases a patient with AMI undergoes from arrival at the hospital emergency room center to thrombolysis in the ICU. The intrahospital delay in patient care was examined. Times were recorded on a specific register of all patients with priority I AMI (clear criteria for fibrinolysis) who were seen at our center. Total time to fibrinolysis in the ICU was 60 minutes (excessive intrahospital delay). A corrective intervention plan was designed and implemented, which reduced the delay to an acceptable 30 minutes. This improved the quality of care of AMI patients at our center.

Accuracy of routinely collected clinical data on acute medical admissions to one hospital

Despite the rapid growth in routine computerized data collection within the National Health Service (NHS), and the increased use of such data for generating hospital statistics and doctor activity rates, few validation studies exist. During a study of 158 acute medical admissions, and examination of hospital data revealed numerous and systematic inaccuracies. If general practitioner (GP) performance statistics are to be reliably based on such sources, data validation, staff training, and protocols for data entry should form a routine part of NHS practice.

Developing efficiency standards to improve service in hospital admitting

The efficiency of admitting services at York Central Hospital in Richmond Hill, ON, Canada, was studied in terms of the timing of admissions. Over a 10-month period, information was collected relating to 1,630 patients' admissions. This information resulted in recommendations allowing the standard of waiting time to be changed and the standard of an admission time to be set. The patient wait time now is to be no longer than 15 minutes with an acceptable level of 80%. The information gathered in a 6-month period during the original 10 months of study showed that the admission process takes no longer than 18 minutes with an acceptable level of 90%.

Epidemiology of non-intentional injuries in an Australian urban region: results from injury surveillance

Injury surveillance provides an opportunity to determine non-intentional injury rates for those injuries which are treated in hospital accident and emergency departments. The first full calendar year of injury surveillance in north-western greater Melbourne was used to calculate incidence rates of a wide range of injury types and causes for 1989. In a population at risk estimated to number 150,604 children aged 0-14 years, the all-cause injury mortality was 10.5/100,000 per year (95% confidence interval [Cl], 5.4-15.8). There were 8207 attendances by children from the denominator area for non-intentional injury at the three hospitals participating in surveillance, representing rates of 6437/100,000 per year (95% Cl, 6258-6616) and 4406/100,000 per year (95% Cl, 4254-4558) for boys and girls respectively, while the rates for admission to hospital were 957/100,000 per year (95% Cl, 888-1025) and 649/100,000 per year (95% Cl, 590-707). The leading causes of hospital attendance were related to injuries involving sports, play equipment, bicycles and poisoning. These rates are substantially lower than those reported from other countries. The possible reasons for this include differences in health care utilization, under-ascertainment of cases, and a real difference in injury risk. Injury Surveillance Information System codes are defined for a standard set of injuries and injury causes which may be used for future comparative studies. Problems related to assessing the reliability of injury ascertainment are discussed, and the importance of integrating injury surveillance into routine hospital information systems is emphasized.

Hospital response variation to the demands of preadmission certification

This paper reports findings from a study of the impact of preadmission certification programs from the perspective of the hospital--a deeply affected party. A series of field studies was undertaken to explore and delineate the range of hospital responses to the challenges posed by this third-party payer mandate and to identify factors associated with variation in responses. The evidence presented suggests wide variation in how hospitals chose to share responsibility for pre-certification with physicians and patients. The findings are broadly consistent with a proposed model that hospital response is determined by both external and internal considerations, but a larger scale hospital survey is necessary to test the hypotheses that can be derived from this study.

Admission source to the medical intensive care unit predicts hospital death independent of APACHE II score

This study was conducted to determine if the source of admission to the medical intensive care unit (MICU) is associated with hospital death independent of the Acute Physiology and Chronic Health Evaluation (APACHE) II score. We calculated APACHE II scores and predicted risks of hospital death for 235 patients who were admitted to the MICU. The predicted death rate was the same as the actual rate for patients who were admitted directly from the emergency department (25% vs 22%), but was less than the actual rate for patients who were transferred from hospital floors (38% vs 55%), the medical intermediate care unit (32% vs 59%), and other hospitals (21% vs 36%). Logistic regression analysis confirmed an independent association between the MICU admission source and risk of death. Our findings suggest that APACHE II does not measure illness severity accurately in all patients who are admitted to intensive care units. If our results are generalizable, using APACHE II to compare intensive care outcomes among hospitals could lead to wrong conclusions about quality of care. Improving predictions of hospital death rates among patients who are in MICUs may require the inclusion of new types of information in the classification system.

The impact of prospectively set hospital budgets on psychiatric admissions

This article examines the impact of prospectively set hospital budgets on rates of admission of psychiatric patients in New York state, U.S.A. The analysis takes advantage of a natural experiment which took place in the early 1980s, whereby a geographic region adopted a prospective hospital budget reimbursement scheme that differed from the prospective per diem reimbursement scheme used in the rest of the state. The results indicate a strong decrease in psychiatric admissions attributable to the experimental payment method.
