This study summarizes the findings of a national survey of inpatient geriatric services in Australia conducted in 2001. These data are unique as there are no uniform administrative data systems available to provide this information. Eight hundred and eighty-eight hospitals were surveyed and full responses were received from 690, representing 78% of hospitals and 85% of all hospital beds. The results illustrated wide variation in the style and level of provision of services among hospitals and across regional and state jurisdictions. 相似文献

OBJECTIVES: To identify risk factors for deep vein thrombosis (DVT) in older patients with restricted mobility or functional disability.
DESIGN: Cross-sectional.
SETTING: Forty-two postacute care departments in France.
PARTICIPANTS: Eight hundred twelve patients aged 65 and older.
MEASUREMENTS: Twenty-two predefined characteristics were investigated, including medical and surgical risk factors, dependence in six basic activities of daily living (ADLs) rated using the Katz index, mobility, the reported value of the Timed Up and Go Test, and pressure ulcers. All patients underwent lower limb ultrasonography on the day of the cross-sectional study.
RESULTS: DVT was found in 113 patients (14%, 33 proximal DVTs (4%) and 80 isolated distal DVTs (10%)). A positive trend was found in the odds of DVT for higher values on the Timed Up and Go Test for patients who were not bedridden or confined to a chair ( P =.007). In two-level multivariable analysis adjusting for prophylaxis against venous thromboembolism, independent risk factors for DVT were aged 80 and older (adjusted odds ratio (aOR)=1.71, 95% confidence interval (CI)=1.05–2.79), previous history of venous thromboembolism (aOR=2.03, 95% CI=1.06–3.87), regional or metastatic-stage cancer (aOR=2.71, 95% CI=1.27–5.78), dependence in more than three ADLs (aOR=2.18, 95% CI=1.38–3.45), and pressure ulcers (aOR=1.85, 95% CI=1.05–3.24).
CONCLUSION: Severe dependence in basic ADLs and higher Timed Up and Go Test score are associated with greater odds of DVT in older patients in postacute care facilities in France. 相似文献

Ambulatory health care use by patients in a public hospital emergency department 总被引:5,自引:0,他引:5 下载免费PDF全文

OBJECTIVE: To describe primary care clinic use and emergency department (ED) use for a cohort of public hospital patients seen in the
ED, identify predictors of frequent ED use, and ascertain the clinical diagnoses of those with high rates of ED use.
DESIGN: Cohort observational study.
SETTING: A public hospital in Atlanta, Georgia.
PATIENTS: Random sample of 351 adults initially surveyed in the ED in May 1992 and followed for 2 years.
MEASUREMENTS AND MAIN RESULTS: Of the 351 patients from the initial survey, 319 (91%) had at least one ambulatory visit in the public hospital system during
the following 2 years and one third of the cohort was hospitalized. The median number of subsequent ED visits was 2 (mean
6.4), while the median number of visits to a primary care appointment clinic was 0 (mean 1.1) with only 90 (26%) of the patients
having any primary care clinic visits. The 58 patients (16.6%) who had more than 10 subsequent ED visits accounted for 65.6%
of all subsequent ED visits. Overall, patients received 55% of their subsequent ambulatory care in the ED, with only 7.5%
in a primary care clinic. In multivariate regression, only access to a telephone (odds ratio [OR] 0.48; 95% confidence interval
[CI] 0.39, 0.60), hospital admission (OR 5.90; 95% CI 4.01, 8.76), and primary care visits (OR 1.68; 95% CI 1.34, 2.12) were
associated with higher ED visit rates. Regular source of care, insurance coverage, and health status were not associated with
ED use. From clinical record review, 74.1% of those with high rates of use had multiple chronic medical conditions, or a chronic
medical condition complicated by a psychiatric diagnosis, or substance abuse.
CONCLUSIONS: All subgroups of patients in this study relied heavily on the ED for ambulatory care, and high ED use was positively correlated
with appointment clinic visits and inpatient hospitalization rates, suggesting that high resource utilization was related
to a higher burden of illness among those patients. The prevalence of chronic medical conditions and substance abuse among
these most frequent emergency department users points to a need for comprehensive primary care. Multidisciplinary case management
strategies to identify frequent ED users and facilitate their use of alternative care sites will be particularly important
as managed care strategies are applied to indigent populations who have traditionally received care in public hospital EDs.

目的在军队编制体制改革期,探讨某军队医院护士的工作压力、应对方式的现状及其关系。方法采用一般资料调查表、护士工作压力源量表、简易应对方式问卷,对266名某军队医院护士进行调查。结果①某军队医院护士工作压力源总均分为(2.08±0.14),工作量及时间分配得分为(2.55±0.33),位于首位;②应对方式与常模比较,消极应对方式低于常模(t=-36.093,P0.01);③工作压力与消极应对方式呈显著负相关(r=-0.280,P0.01)。结论军队医院护士采用消极应对方式较少,采取积极应对方式越多,工作压力越小。 相似文献

三甲医院提升患者感知价值策略研究 总被引:1,自引:0,他引:1
随机抽取了广州地区10家三甲医院进行问卷调查。结果显示,患者感知价值与预期价值有一定落差。对此,医院应切实采取重视医患有效沟通、改善医护人员态度、提供及时服务、形成良性互动的意见反馈机制、缩短患者就诊等候时间等措施来提升患者感知价值。 相似文献
