BACKGROUND: Previous studies of hospital utilization have not taken into account the use of acute care beds for subacute care. The authors determined the proportion of patients who required acute, subacute and nonacute care on admission and during their hospital stay in general hospitals in Ontario. From this analysis, they identified areas where the efficiency of care delivery might be improved. METHODS: Ninety-eight of 189 acute care hospitals in Ontario, at 105 sites, participated in a review that used explicit criteria for rating acuity developed by Inter-Qual Inc., Marlborough, Mass. The records of 13,242 patients who were discharged over a 9-month period in 1995 after hospital care for 1 of 8 high-volume, high-variability diagnoses or procedures were randomly selected for review. Patients were categorized on the basis of the level of care (acute, subacute or nonacute) they required on admission and during subsequent days of hospital care. RESULTS: Of all admissions, 62.2% were acute, 19.7% subacute and 18.1% nonacute. The patients most likely to require acute care on admission were those with acute myocardial infarction (96.2% of 1826 patients) or cerebrovascular accident (84.0% of 1596 patients) and those admitted for elective surgery on the day of their procedure (73.4% of 3993 patients). However, 41.1% of patients awaiting hip or knee replacement were admitted the day before surgery so did not require acute care on admission. The proportion of patients who required acute care on admission and during the subsequent hospital stay declined with age; the proportion of patients needing nonacute care did not vary with age. After admission, acute care was needed on 27.5% of subsequent days, subacute care on 40.2% and nonacute care on 32.3%. The need for acute care on admission was a predictor of need for acute care during subsequent hospital stay among patients with medical conditions. The proportion of patients requiring subacute care during the subsequent hospital stay increased with age, decreased with the number of inpatient beds in each hospital and was highest among patients with congestive heart failure, chronic obstructive pulmonary disease and pneumonia. INTERPRETATION: In 1995, inpatients requiring subacute care accounted for a substantial proportion of nonacute care days in Ontario''s general hospitals. These findings suggest a need to evaluate the efficiencies that might be achieved by introducing a subacute category of care into the Canadian health care system. Generally, efforts are needed to reduce the proportion of admissions for nonacute care and of in-hospital days for other than acute care. 相似文献

OBJECTIVE: To assess longitudinal trends in admissions, management, and inpatient mortality from acute myocardial infarction over 10 years. DESIGN: Retrospective analysis based on the Nottingham heart attack register. SETTING: Two district general hospitals serving a defined urban and rural population. SUBJECTS: All patients admitted with a confirmed acute myocardial infarction during 1982-4 and 1989-92 (excluding 1991, when data were not collected). MAIN OUTCOME MEASURES: Numbers of patients, background characteristics, time from onset of symptoms to admission, ward of admission, treatment, and inpatient mortality. RESULTS: Admissions with acute myocardial infarction increased from 719 cases in 1982 to 960 in 1992. The mean age increased from 62.1 years to 66.6 years (P < 0.001), the duration of stay fell from 8.7 days to 7.2 days (P < 0.001), and the proportion of patients aged 75 years and over admitted to a coronary care unit increased significantly from 29.1% to 61.2%. A higher proportion of patients were admitted to hospital within 6 hours of onset of their symptoms in 1989-92 than in 1982-4, but 15% were still admitted after the time window for thrombolysis. Use of beta blockers increased threefold between 1982 and 1992, aspirin was used in over 70% of patients after 1989, and thrombolytic use increased 1.3-fold between 1989 and 1992. Age and sex adjusted odds ratios for inpatient mortality remained unchanged over the study period. CONCLUSIONS: Despite an increasing uptake of the "proved" treatments, inpatient mortality from myocardial infarction did not change between 1982 and 1992. 相似文献

OBJECTIVE: To determine whether perinatal care in southwestern Ontario is regionalized, to identify trends over time in referral patterns, to quantify trends in perinatal death rates and to identify trends in perinatal death rates that give evidence of regionalization. DESIGN: Cohort study. SETTING: Thirty-two hospitals in southwestern Ontario (1 level III, 1 modified level III and 30 level II or I). PATIENTS: All pregnant women admitted to the hospitals and their infants. MAIN OUTCOME MEASURES: Antenatal and neonatal transfer status, live-born with discharge home alive from hospital of birth, stillborn, and live-born with death before discharge. RESULTS: Between 1982 and 1985 the antenatal transfer rate increased from 2.2% to 2.8% (p less than 0.003). The proportion of births of infants weighing 500 to 1499 g increased from 49% to 69% at the level III hospital. The neonatal transfer rate increased from 26.2% to 47.9% (p less than 0.05) for infants in this birth-weight category and decreased from 10.2% to 7.1% (p less than 0.03) for infants weighing 1500 to 2499 g. The death rate among infants of low birth weight was lowest among those born at the level III centre and decreased at all centres between 1982 and 1985. CONCLUSIONS: Perinatal care in southwestern Ontario is regionalized and not centralized; regionalization in southwestern Ontario increased between 1982 and 1985. 相似文献

The present prospective study included 106 horses referred to the Department of Large Animal Sciences, The Norwegian School
of Veterinary Science, as non-responders to the initial colic treatment in general practise. In 14 of these cases a required
surgical treatment was not performed due to economical or other reasons and were excluded from the study. Clinical and laboratory
data were obtained at the arrival in the hospital. The outcome for all analyses was survival/non-survival. A multivariable
logistic regression was performed. The analyses were used in medically (46 horses) and surgically treated cases (46 horses)
separately. The same analyses were also run for all 92 horses in a simulated "field" situation, where only clinical variables
and D-dimer values were included. The fraction of survivors was 78% in the medical and 48% in the surgical cases. In total
63% of the horses survived. In the final multivariable logistic regression model packed cell volume (PCV) was the only important
predictor for medically treated cases, and heart rate and presence of hyperaemic or cyanotic mucous membranes were the predictors
in the surgically treated cases as well as in the simulated "field" situation. In conclusion, traditional variables as heart
rate, mucous membranes and PCV were the important predictors for the outcome in hospitalised colic cases. 相似文献

In Ontario in the past 25 years, the death rate from cancer of the lung has shown a substantial increase, ninefold for males and twofold for females. The male:female ratio varied from an average of 8.5:1 to as high as 11.7:1 at the ages 65 to 69. From 1938 to 1958, one-quarter of the total cases (2457) were treated in Ontario Cancer Clinics. Survival rates were: for one year, 20%; three years, 6.5%, and for five years, 3.8%. Fifty-four per cent of surgically treated patients and 63% treated by resection and radiotherapy were alive one year after treatment. Of 821 cases treated with orthovoltage the one-year survival rate was 14%, and of 862 cases treated with cobalt therapy, 23%. It was concluded that this improvement in results may be attributed to the difference in treatment. 相似文献

BACKGROUND: There is relatively little information available on recent population-based trends in the outcomes of patients who have had an acute myocardial infarction (AMI). We, therefore, conducted a study of temporal trends in the outcomes of AMI patients in Ontario, Canada, between the 1992 and 1996 fiscal years. METHODS: 114,618 AMI patients were discharged from hospitals in Ontario between Apr. 1, 1992, and Mar. 31, 1997. After specific exclusion criteria were applied the final sample of 89,456 patients was divided into 5 cohorts according to the fiscal year of discharge. As part of the Ontario Myocardial Infarction Database project the linked administrative data pertaining to these patients were used to examine cohort characteristics, cardiac procedures used and mortality rates for each of the 5 cohorts over time. RESULTS: There was a significant increase in the percentage of patients in Ontario receiving coronary angiography, percutaneous transluminal coronary angioplasty and coronary artery bypass grafting surgery (p < 0.001) after an AMI between 1992 and 1996. In addition, the overall 30-day risk-adjusted mortality rate declined from 15.5% in 1992 to 14.0% in 1996 (p = 0.001) and the 1-year risk-adjusted mortality rate declined from 23.7% in 1992 to 22.3% in 1996 (p = 0.017). Virtually all of the improvement occurred within 30 days of admission. The absolute decline in 1-year mortality rates was significant for patients under the age of 65 (2.3%, 95% confidence interval [CI] 1.4% to 3.2%) and for males (1.2%, 95% CI 0.2% to 2.2%); absolute declines were not significant for patients 65 years of age or older (0.7%, 95% CI -0.6% to 2.0%) and for female patients (-0.1%, 95% CI -1.7% to 1.5%). Interestingly, post-infarction coronary angiography and coronary artery bypass grafting rates were consistently lower in the older and the female patients throughout the study period. INTERPRETATION: There was a modest improvement in the short- and long-term survival of patients in Ontario after an AMI between 1992 and 1996. The Ontario experience suggests that recent advances in AMI management have been of more benefit to younger and male AMI patients. 相似文献

ABSTRACT: BACKGROUND: Primary health care delivery in the developing world faces many challenges. Priority setting favours HIV, TB and malaria interventions. Little is known about the challenges faced in this setting with regard to critical care medicine. The aim of this study was to analyse and categorise the diagnosis and outcomes of 1,774 patients admitted to a hospital intensive care unit (ICU) in a low-income country over a 7-year period. We also assessed the country's ICU bed capacity and described the challenges faced in dealing with critically ill patients in this setting. FINDINGS: A retrospective audit was conducted in a general ICU in a university hospital in Uganda. Demographic data, admission diagnosis, and ICU length of stay were recorded for the 1,774 patients who presented to the ICU in the period January 2003 to December 2009. Their mean age was 35.5 years. Males accounted for 56.5% of the study population; 92.8% were indigenous, and 42.9% were referrals from upcountry units. The average mortality rate over the study period was 40.3% (n = 715). The highest mortality rate (44%) was recorded in 2004 and the lowest (33.2%) in 2005. Children accounted for 11.6% of admissions (40.1% mortality). Sepsis, ARDS, traumatic brain injuries and HIV related conditions were the most frequent admission diagnoses. A telephonic survey determined that there are 33 adult ICU beds in the whole country. CONCLUSIONS: Mortality was 40.1%, with sepsis, head injury, acute lung injury and HIV/AIDS the most common admission diagnoses. The country has a very low ICU bed capacity. Prioritising infectious diseases poses a challenge to ensuring that critical care is an essential part of the health care package in Uganda. 相似文献

BACKGROUND: Acute care hospitals in Quebec are required to reserve 10% of their beds for patients receiving long-term care while awaiting transfer to a long-term care facility. It is widely believed that this is inefficient because it is more costly to provide long-term care in an acute care hospital than in one dedicated to long-term care. The purpose of this study was to compare the quality and cost of long-term care in an acute care hospital and in a long-term care facility. METHODS: A concurrent cross-sectional study was conducted of 101 patients at the acute care hospital and 102 patients at the long-term care hospital. The 2 groups were closely matched in terms of age, sex, nursing care requirements and major diagnoses. Several indicators were used to assess the quality of care: the number of medical specialist consultations, drugs, biochemical tests and radiographic examinations; the number of adverse events (reportable incidents, nosocomial infections and pressure ulcers); and anthropometric and biochemical indicators of nutritional status. Costs were determined for nursing personnel, drugs and biochemical tests. A longitudinal study was conducted of 45 patients who had been receiving long-term care at the acute care hospital for at least 5 months and were then transferred to the long-term care facility where they remained for at least 6 months. For each patient, the number of adverse events, the number of medical specialist consultations and the changes in activities of daily living status were assessed at the 2 institutions. RESULTS: In the concurrent study, no differences in the number of adverse events were observed; however, patients at the acute care hospital received more drugs (5.9 v. 4.7 for each patient, p < 0.01) and underwent more tests (299 v. 79 laboratory units/year for each patient, p < 0.001) and radiographic examinations (64 v. 46 per 1000 patient-weeks, p < 0.05). At both institutions, 36% of the patients showed anthropometric and biochemical evidence of protein-calorie undernutrition; 28% at the acute care hospital and 27% at the long-term care hospital had low serum iron and low transferrin saturation, compatible with iron deficiency. The longitudinal study showed that there were more consultations (61 v. 37 per 1000 patient-weeks, p < 0.02) and fewer pressure ulcers (18 v. 34 per 1000 patient-weeks, p < 0.05) at the acute care hospital than at the long-term care facility; other measures did not differ. The cost per patient-year was $7580 higher at the acute care hospital, attributable to the higher cost of drugs ($42), the greater use of laboratory tests ($189) and, primarily, the higher cost of nursing ($7349). For patients requiring 3.00 nursing hours/day, the acute care hospital provided more hours than the long-term care facility (3.59 v. 3.03 hours), with a higher percentage of hours from professional nurses rather than auxiliary nurses or nursing aides (62% v. 28%). The nurse staffing pattern at the acute care hospital was characteristic of university-affiliated acute care hospitals. INTERPRETATION: The long-term care provided in the acute care hospital involved a more interventionist medical approach and greater use of professional nurses (at a significantly higher cost) but without any overall difference in the quality of care. 相似文献

Involuntary admission to hospital and treatment in Ontario: is pessimism among physicians warranted?
In 1978 the Ontario Mental Health Act was revised to contain more specific and objective criteria for involuntary admission to hospital and treatment. The new requirements have elicited critical and pessimistic comments from psychiatrists and other physicians in Ontario. Two recent cases, described in this paper, indicate that the changes in the law have not obstructed good clinical care and treatment and may, in fact, be salutary to the management of patients who are involuntarily admitted to hospital. 相似文献

This is a preliminary report of a co-operative study of 1,203 episodes of acute myocardial infarction in men under 70 years in four centres in the south west of England. The mortality at 28 days was 15%. A comparison is made between home care by the family doctor and hospital treatment initially in an intensive care unit: 343 cases were allocated at random. The randomized groups do not differ significantly in composition with respect to age; past history of angina, infarction, or hypertension; or hypotension when first examined. The mortality rates of the random groups are similar for home and hospital treatment. The group sent electively to hospital contained a higher proportion of initially hypotensive patients whose prognosis was bad wherever treated; those who were not hypotensive fared rather worse in hospital.For some patients with acute myocardial infarction seen by their general practitioner home care is ethically justified, and the need for general admission to hospital should be reconsidered. 相似文献

We reviewed data on hospital care of HIV/AIDS patients at Lazzaro Spallazani Institute between 1991 and 1999. The number of newly diagnosed AIDS cases increased until 1995 and decreased constantly thereafter. The proportion of AIDS cases diagnosed at our institution over the total number of cases reported in our region and in our country increased from 31.2 to 59.8% and from 3.9 to 8.7% respectively (p<0.001). In the entire study period, 10044 out of 18,434 (54.5%) of patients admitted to acute care wards were diagnosed with HIV related pathologies. The number of admission of HIV/AIDS patients to acute-care wards increased until 1995 and remained constant thereafter. Our data suggest that a consistent need for inpatient hospital care remains even in the era of HAART. 相似文献

In a three-year period a community hospital of 40 beds discharged 2086 patients, their mean length of stay being 14.8 days. Some 68% of the patients treated were over 65, and 8.9% died in hospital. While the most common diagnosis on admission was disease of the respiratory tract, this does not indicate the actual cause of admission. For 142 patients from one practice this was acute illness in 44% of the cases, assessment in 20%, and a need for nursing care in 36%. If the community hospital had not been available about half these patients would have been admitted to the general hospital. 相似文献

OBJECTIVE: To describe characteristics associated with inappropriate hospital use by patients in Manitoba in order to help target concurrent utilization review. Utilization review was developed to reduce inappropriate hospital use but can be a very resource-intensive process. DESIGN: Retrospective chart review of a sample of adult patients who received care for medical conditions in a sample of Manitoba hospitals during the fiscal year 1993-94; assessment of patients at admission and for each day of stay with the use of a standardized set of objective, nondiagnosis-based criteria (InterQual). PATIENTS: A total of 3904 patients receiving care at 26 hospitals. OUTCOME MEASURES: Acute (appropriate) and nonacute (inappropriate) admissions and days of stay for adult patients receiving care for medical conditions. RESULTS: After 1 week, 53.2% of patients assessed as needing acute care at admission no longer required acute care. Patients 75 years of age or older consumed more than 50% of the days of stay, and 74.8% of these days of stay were inappropriate. Four diagnostic categories accounted for almost 60% of admissions and days, and more than 50% of those days of stay were inappropriate. Patients admitted through the emergency department were more likely to require acute care (60.9%) than others (41.7%). Patients who were Treaty Indians had a higher proportion of days of stay requiring acute care than others (45.9% v. 32.8%). Patients'' income and day of the week on admission (weekday v. weekend) were not predictive factors of inappropriate use. CONCLUSION: Rather than conducting a utilization review for every patient, hospitals might garner more information by targeting patients receiving care for medical conditions with stays longer than 1 week, patients with nervous system, circulatory, respiratory or digestive diagnoses, elderly patients and patients not admitted through the emergency department. 相似文献

In recent years the Ontario government has been concerned that the proportion of public expenditures devoted to health care is at an all-time high. In addition, the media have devoted considerable attention to specific incidents that may represent inadequate funding of hospital services. To shed light on the debate on health care expenditures we analysed the trend in expenditures of Ontario''s hospital sector in the 1980s in terms of the amount of inputs (e.g., labour) used to produce hospital services (e.g., a patient-day or admission) and after adjustment for general inflation. As in the 1970s the number of inputs grew relatively slowly during the 1980s. Inputs per patient-day grew at an annual rate of 0.46% and inputs per admission at an annual rate of 2.4%. Cost increases were largely accounted for by hospital wage increases; this could have been due to Ontario''s rapidly expanding economy. These findings indicate that Ontario has continued to be successful in containing the number of inputs used in the hospital sector. However, after two decades of substantial success with publicly acceptable cost control, the government faces increased scrutiny as the media and the public focus attention on several areas of perceived inadequate funding in health care services. 相似文献

In the South-west Thames Region over the period 1970-8 the number of admissions for asthma in children aged 5-14 years increased from 256 to 684, an increase of 167%. Factors associated with this trend were investigated by an analysis of routine hospital statistics and examination of case notes for 1970 and 1978 from every hospital in the region. The trend was caused partly by an increase in readmission rates. There was a more than fivefold increase in self-referrals; these patients had less severe asthma on admission and a higher readmission rate than patients referred by general practitioners. Drug management before and after admission changed considerably over the nine years, as did hospital investigations. Overall, there was little change in the level of severity on admission. The increase in admissions was not associated with a reduction in deaths from asthma in the region and occurred in spite of major advances in the drug control of asthma; this indicates an inadequacy of ambulatory care. The shift in the balance of care towards the hospital and the increasing adoption of a primary care function by the hospital indicate a need for hospitals and general practice to agree jointly on management policies for acute asthma. 相似文献

A cohort study of health status was undertaken to determine the patterns of morbidity in the first year of life for Indian and non-Indian infants living in southern Ontario. The annual incidence of office-reported health problems was 8.0 episodes for the 99 Indians and 4.5 for the 316 non-Indians studied. The risk of illness of most diagnostic categories was more than 1.5 times greater and the rate of hospital admission 4 times greater for the Indian infants. There was no difference between the two cohorts in the rates of visits to hospital emergency departments. The main cause of illness in both cohorts was respiratory tract infection; lower respiratory tract infections, particularly pneumonia, were a major health problem among the Indian infants. Only 36% of the Indian infants compared with 68% of the non-Indian infants attended five or more well-baby examinations. Part of the difference in morbidity between the Indian and non-Indian infants may be attributed to environmental factors, health care behaviour and geographic constraints. 相似文献

A 4-week, province-wide nurses'' strike in Alberta in 1982 caused the closure of 57% of the acute care beds, including 47% of the intensive care beds, in Calgary. The effects of the strike on patient care at Foothills Provincial General Hospital, where nurses did not strike, were assessed. The number of emergency admissions, severity of illness and rate of death in the intensive care unit increased. On the other hand, the rate of death, length of stay and number of unexpected deaths on the medical wards were similar to those in the control periods before and after the strike. A subjective perception by hospital personnel of deteriorating patient care caused much anxiety; however, the results of analysis of measurable aspects of care suggested that the patients admitted to hospital received care during the strike that was comparable to care given before or after the strike. The inconvenience and potential harm to the patients not admitted because they had less severe illness were not measured. 相似文献

Overcrowding in emergency departments presents serious problems to both patients and hospital staff. At Scarborough (Ontario) General Hospital this problem was becoming potentially dangerous until a hospital committee instituted a series of changes that dramatically improved the situation. A geriatrician was appointed to assess and care for the increasing number of elderly and chronic care patients. The beds in various services were reallocated, and more beds were given to the medical service. Surgeons agreed to perform more surgery on an outpatient basis, and the Short-Stay and Ambulatory Procedures units were expanded to handle more procedures. In addition, the implementation of a physician-managed admission system ensured the appropriate admission of patients. The entire system is monitored, and the committee meets regularly to deal with any problems. 相似文献

OBJECTIVE--To compare quality of care between 1990 and 1992 in patients with self diagnosed joint pain. DESIGN--Questionnaire and record based study. SUBJECTS--Patients identified at consecutive consultations during two weeks in 1990, 1991, and 1992. SETTING--Six practice groups in pilot fundholding scheme in Scotland. MAIN OUTCOME MEASURES--Length of consultation; numbers referred or investigated or prescribed drugs; responses to questions about enablement and satisfaction. RESULTS--About 15% of patients consulted with joint pain each year. 25% (316) of them had social problems in 1990 and 37% (370) in 1992; about a fifth wanted to discuss their social problems. Social problems were associated with a raised general health questionnaire score. The mean length of consultation for patients with pain was 7.6 min in 1990 and 7.7 min in 1992. Patients wishing to discuss social problems received longer consultations (8.5 min 1990; 10.4 min 1992); but other patients with social problems received shorter consultations (7.4 min; 7.2 min). The level of prescribing was stable but the proportion of patients having investigations or attending hospital fell significantly from 1990 to 1992 (31% to 24%; 31% to 13% respectively). Fewer patients responded "much better" to six questions about enablement in 1992 than in 1990. Enablement was better after longer than shorter consultations for patients with social problems. CONCLUSIONS--Quality of care for patients with pain has been broadly maintained in terms of consultation times. The effects of lower rates of investigation and referral need to be investigated further. 相似文献
