Factors related to long-term stay in hospital by elderly people in a Japanese city

Determinants Associated with Prolonged Hospital Stays for Patients Aged 65 Years or Older with a Vertebral Compression Fracture in a Rural Hospital in Japan

Japan is an aging society, and the incidence of diseases related to aging, such as pneumonia, heart failure, vertebral compression fracture (VCF), is increasing. Prolonged hospital stays are becoming a serious social problem, leading to elevated medical expenses. Thus, shortening the period of hospitalization is important. This study aimed to reveal determinants associated with prolonged hospital stays for patients with VCF. Our institution is the primary hospital in a rural area in the Kanto region of Japan. Altogether, 110 patients with a VCF, aged 65 years or older, including 79 women, were divided into two groups according to the average hospital stay period of 28 days: the long-stay group (mean stay 40.0 ± 11.6 days, n = 39) and the short-stay group (mean stay 20.6 ± 4.4 days, n = 71). Notably, the short-stay group included 55 women. Multivariate logistic regression analyses in male showed no variates significantly associated with prolonged hospitalization. By contrast, multivariate logistic regression analyses in female showed requiring emergency transportation to hospital was significantly associated with prolonged hospitalization [odds ratio 7.69, 95% confidence interval 1.13-52.29, P = 0.04]. In conclusion, this study implies that patients with better levels of activities of daily living are able to walk alone sooner and are easily discharged. Furthermore, the patient requiring emergency transportation might be in a poor social living environment, such as living alone. These results may give us a good opportunity to re-consider fundamental problems surrounding the elderly.

Classification of long-term care wards and their functional characteristics: analysis of national hospital data in Japan

Background

In a rapidly aging society that has promoted extensive reforms of the healthcare system, clarifying functional patterns in long-term care wards is important for developing regional healthcare policies. This study aimed to classify patterns of inpatient characteristics among Japanese long-term care wards and to examine hospital/ward characteristics.

Methods

We analyzed data from 1856 long-term care wards extracted from the 2014 Annual Report for Functions of Medical Institutions in Japan. We classified five clusters of long-term care wards based on inpatients’ medical acuity/activities of daily living using cluster analysis, and compared hospital/ward characteristics across the clusters with a chi-square test or analyses of variance.

Results

Cluster 1 was low medical acuity/high activities of daily living (n = 175); cluster 2, medium medical acuity/high activities of daily living (n = 340); cluster 3, medium medical acuity/low activities of daily living (n = 461); cluster 4, high medical acuity/low activities of daily living (n = 409); and cluster 5, mixed (n = 471). Although clusters 1 and 2 had similar higher proportions of home discharge (48.1% and 34.6%, respectively), there was a difference in length of hospital stay between the clusters (154.6 and 216.6 days, respectively). On the other hand, clusters 3 and 4 experienced a longer length of hospital stay (295.7 and 239.8 days, respectively) and a higher proportion of in-hospital deaths (42.7% and 50.2%, respectively). Characteristics of cluster 5 were not significantly different from the average of overall wards.

Conclusions

There were distinctive differences across hospitals in their use of long-term care wards. Wards with different functions have different support needs; the clusters with high activities of daily living needed support in promoting home discharge, while those with low activities of daily living needed support in providing quality end-of-life care. Our results can be useful for constructing the future regional healthcare system. This study also suggests introducing a standardized patient classification system in long-term care settings.

Sleep apnoea syndrome as a risk for mortality in elderly inpatients

OBJECTIVE

The characteristics of sleep apnoea syndrome (SAS) in the elderly, including subtype classification and association with mortality, have not been fully elucidated. This study examined these factors in an elderly Japanese inpatient population.

METHODS

Overnight polysomnography was used to diagnose and classify SAS in 145 elderly inpatients (mean ± age 81 ± 8 years). Clinical data, including brain computerized tomography findings, were recorded. The study population included nine inpatients with obstructive SAS, 12 with central SAS, 25 with mixed SAS and 99 controls (no SAS).

RESULTS

Increased body mass index and grade of aortic arch calcification independently contributed to risk of all subtypes of SAS combined. There was an independent association between SAS and increased risk of mortality from all causes as well as from pneumonia and from cardiovascular disease. Only mixed SAS was independently and positively associated with increased risk of death from pneumonia.

CONCLUSIONS

Obstructive, central and mixed SAS were associated with increased risk of cardiovascular related and all-cause mortality. Mixed SAS was associated with an increase in mortality from pneumonia. There was no relationship between mortality and severity of SAS.

Healthcare consumption in men and women aged 65 and above in the two years preceding decision about long-term municipal care

The aim was to investigate healthcare consumption in men and women aged 65 and above in the two years preceding decision about long-term municipal care at home or in special accommodation and to investigate determinants for healthcare consumption. The study comprised 362 people (aged 65 or over), all subject to a decision about municipal care and/or services during 2002-2003, drawn from the Swedish National Study on Aging and Care (SNAC). Data were collected from three existing registers, the SNAC data covered age, gender, marital status, functional ability, informal care and living conditions and were merged with the Skåne County Council's patient administration system PASiS and PrivaStat covering healthcare consumption from the year 2000 and forward. About 50% of the acute hospital stays (n = 392) occurred within 5 months prior to municipal care. The men (n = 115, mean age 80.8) had significantly longer stays in hospital (P = 0.025), more diagnoses (P = 0.004) and contacts with other staff groups beside physicians in outpatient care (P < 0.001) compared to the women (n = 247, mean age 83.8). The regression analysis showed heart conditions, cancer, musculoskeletal problems, genitourinary diseases, injuries and unspecified symptoms to be significantly associated with various kinds of healthcare consumption. The findings indicated a breakpoint in terms of hospital admissions about 5 months prior to municipal care and service and a share of 15% having several admissions to hospital. Early detection and preventive interventions to these people in a transitional stage of becoming increasingly dependent on continuous care and services seems urgent to prevent escalating acute healthcare consumption.

Angiotensin I-converting enzyme inhibitor improves reactive hyperemia in elderly hypertensives with arteriosclerosis obliterans

Endothelial function in elderly hypertensive patients with arteriosclerosis obliterans has not been evaluated. We examined whether antihypertensive drugs improve vasodilatory response to reactive hyperemia of the limbs in elderly hypertensive patients (83 +/- 8 [SD] years) without (n=46, 0.9 < or = ankle-brachial pressure index < or = 1.4) and with (n=24) arteriosclerosis obliterans (ankle-brachial pressure index < 0.2). Patients were randomized for treatment with monotherapy of either temocapril (14 with and 26 without arteriosclerosis obliterans) or amlodipine (10 with and 20 without arteriosclerosis obliterans) for 6 months. Blood flows of the forearms and legs were measured by strain-gauge plethysmography. The vasodilatory response to the release of compression of the forearms and thighs at 200 mmHg or 20 mmHg more than systolic blood pressure for 5 min and to sublingual administration of nitroglycerin (0.3 mg) was assessed. The maximum reactive hyperemic flow in 35 legs with arteriosclerosis obliterans was significantly (p < 0.001) decreased compared to the value in legs in the control hypertensive subjects. Moreover, maximum reactive hyperemic flow in the forearms of patients with arteriosclerosis obliterans was significantly (p = 0.002) decreased compared to that in the control subjects. Blood pressure was similarly decreased by treatment with temocapril or amlodipine. Response to nitroglycerin (0.3 mg) was not changed by either drug. Treatment with temocapril significantly improved maximum reactive hyperemic flow of not only the legs and forearms in control hypertensives but also the legs and forearms in patients with arteriosclerosis obliterans, and attenuated the worsening of activity of daily living in these patients, although treatment with amlodipine did not. These results suggest that the angiotensin-converting enzyme inhibitor temocapril has a beneficial effect on endothelial function in elderly patients with arteriosclerosis obliterans.

Tilting-Induced Decrease in Systolic Blood Pressure in Bedridden Hypertensive Elderly Inpatients: Effects of Azelnidipine

The object of this study was to examine blood pressure (BP) variability due to postural change in elderly hypertensive patients. The subjects studied were 154 elderly inpatients in a hospital for the elderly (48 male and 106 female; median age: 82 years), consisting of age- and sex-matched bedridden (n=39) and non-bedridden (n=39) normotensive controls and bedridden (n=38) and non-bedridden (n=38) hypertensive patients. BP and pulse rate (PR) were measured in the supine position, then again after a 2-min, 45 deg head-up tilt with the legs horizontal. The decrease in systolic BP (SBP) on tilting in the bedridden hypertensive group (median: -10 mmHg; range: -32 to 9 mmHg) was significantly (p<0.008) greater than those in the other three groups. Monotherapy with azeinidipine, a long-acting calcium channel blocker, for 3 months not only significantly reduced the basal BP and PR of hypertensive patients in the two groups, but also significantly (p<0.05) attenuated the tilt-induced decrease in the SBP to -3 mmHg (-19 to 25 mmHg) and enhanced the change in PR from -1 bpm (-10 to 7 bpm) to 1 bpm (-4 to 23 bpm) in the bedridden hypertensive group. Our findings indicate that tilt-induced decrease in SBP is a rather common phenomenon in bedridden elderly hypertensive patients, and that treatment with azelnidipine attenuates tilt-induced decrease in SBP, probably through an improvement of baroreceptor sensitivity.

Impact of sociocultural factors on hospital length of stay in children with nephrotic syndrome in Japan

Hospital length of stay (LOS) of Japanese inpatients is extraordinarily long, partly because of the nature of the health insurance system in Japan. We investigated factors that affect the LOS in Japan, taking pediatric nephrosis as an example. The characteristics of 78 hospitalized children with steroid-sensitive nephrotic syndrome were studied. The median LOS of the patients was 47 days. Most of the patients' mothers (92.3%) stayed in hospital during admission to care for their children. Using multivariate Cox's regression analysis with time-dependent covariates, non-working mother and smaller number of siblings were found to be factors significantly associated with prolonged LOS. These factors are presumed to allow the mothers to care for their hospitalized children for a long period. No medical or clinical factors played a significant role in the prolonged LOS. These results suggest that sociocultural factors have a greater influence on the LOS in Japan than do medical factors such as disease course, coexisting illness, complications, and treatment response.

Factors related to home discharge of cerebrovascular disease patients: 1-year follow-up interview survey of caregivers of hospitalized patients in 53 acute care hospitals in Japan

In Japan, many disabled elderly people remain hospitalized for long periods. Cerebrovascular diseases (CVD) are the most causes responsible for such disability. To examine the predictors of home discharge in CVD patients, we performed a 1-year follow-up interview of the main caregivers of patients hospitalized with a CVD event. The initial cohort consisted of CVD patients hospitalized in all the second level emergency and general hospitals in Ibaraki Prefecture in February 1992 (N=888 patients in 53 hospitals). In the following year, we performed an interview survey of the main caregivers of these CVD patients. The survey items included the characteristics of the patients (including medical and socioeconomic conditions), caregivers, and family members. The final study population included the main caregivers of 187 home patients and 90 institutionalized patients. We compared these two groups in terms of predictors of discharge to home. The results of multiple logistic regression analysis showed that the following seven factors were related to home discharge; better baseline activities of daily living (ADL), larger improvement in ADL, larger family size, spouse as the caregiver, caregiver without a full-time job, better economic status of the caregiver, and sources of the patient's income. Our study indicated that the caregiver's conditions were closely related to home discharge of the CVD patients. More attention should, therefore, be centered on the caregiver's well-being and economic aspects as well as the patient's conditions in order to encourage home discharge of stroke patients.

Retooling social work practice for high volume, short stay

The re-engineered acute care environment that emphasizes managed care, reduced costs per case and shorter lengths of stay also demands innovative approaches to the delivery of social work service. As departments disappear and other professions compete for roles in counselling, discharge planning and community liaison, there is a real threat to the viability of the acute hospital as a setting for social work. This paper focuses on the adaptive skills needed for the restructured acute care context, including (1) the creation of key roles for social work on the multidisciplinary team, (2) pre-admission high-risk screening and discharge planning, (3) high volume recording, (4) solution-focused brief interventions, and (5) the development of community partnerships. These conceptual strategies are implemented differently in examples drawn from three distinct high-volume patient groups: reconstructive orthopaedics, high-risk fetal assessment and thoracic oncology.

An investigation of the disabled elderly in a geriatric health services facility in an urban area of Japan and attitudes of their family caregiver

We investigated characteristics of 72 clients in a geriatric health services facility (hereafter called GHSF), conditions of their family caregivers, and the factors associated with the caregivers choice of discharge destination. Most of the clients were elderly females with a low degree of independence, and dementia was observed in about 60% of them. The clients had children, but many of them lived alone before admission to the GHSF. The rate of admission from hospitals was high (54%), and that of discharge to hospitals was also high (50%). Sixty-seven percent of the clients stayed in for a period of over six months. Most of the family caregivers were daughters or daughters-in-law, and considered themselves to be healthy. Sixty-three percent of them had jobs, and most of the caregivers had no sub-caregiver to assist them. The family caregivers desired the client's home (19.4%), hospital or another GHSF (54.2%), or nursing home (26.4%) as the discharge destination from the GHSF. According to Hayashi's quantification theory type II, the factors related to the home as the discharge destination desired by client's family caregivers are as follows; caregivers used formal home public health nursing visit service before entering the GHSF, the job of the caregiver was a part-time job, the client did not show dementia, the period of care experience was shorter than one year.

Senile dementia in Japan: prevalence and response

Early studies of the prevalence of dementia in Japan indicated low rates, but more recently rates have been rising to the levels shown in other countries. Extended family care of the elderly has been typical, but recent developments suggest that this is declining. The implications of recent social changes for the care of the demented elderly are discussed.

Extended hospital stays with increasing age: the impact of an acute geriatric unit

OBJECTIVES

To examine the association between increasing age and extended length of hospitalisation, and the impact of an acute geriatric unit on this association.

DESIGN

Retrospective analysis of concurrently collected data of patients admitted to three general medical units, one of which was an acute geriatric unit.

SETTING

Alfred Hospital, Melbourne (a tertiary referral teaching hospital), between 1 July 1993 to 30 June 1994.

PATIENTS

Those classified into the same diagnosis-related groups (DRGs) as the 15 most common DRGs of the acute geriatric unit.

OUTCOME MEASURE

Incidence of patients with extended lengths of stay ("high outliers"), analysed by age, medical unit and DRG.

RESULTS

Of 3499 patients discharged from the hospital with the 15 study DRGs, 303 patients (8.6%) were from the acute geriatric unit, and 274 and 300 patients (7.8% and 8.5%) were from the two other general medical units, respectively. Patients in the acute geriatric unit were significantly older (median age group, 75-79; age range, 18-98) than patients in all other hospital units (median age group, 60-64; age range, 18-97) (P < 0.0001). Analysis of patients with respiratory and cardiovascular DRGs admitted to all general medical units compared with specialty units showed this age discrepancy was even more marked for patients aged over 85. There was an increased likelihood (P < 0.001) of an extended length of stay for patients aged over 55. The incidence of high outliers for comparable DRGs was lower for patients cared for by the acute geriatric unit, compared with general medical units. In the acute geriatric unit, unlike the overall trend, the proportion of high outliers did not increase with age.

CONCLUSIONS

The specialised management of acute geriatric medical units can counteract the trend towards increased incidence of high outliers with increasing age, despite significantly older patients.

Age and marital status are major factors associated with institutionalisation in elderly Hong Kong Chinese

STUDY OBJECTIVE

To determine the need for long term institutional care for elderly Chinese living in Hong Kong and factors associated with institutional living.

DESIGN

Survey by interviewer administered questionnaire of a stratified random sample of all recipients of old age or disability allowance covering 90% of the population.

SETTING

Survey performed in Hong Kong, a city on the south coast of China with an area of 1070 km2 and approximately six million people.

PARTICIPANTS

A total of 2032 subjects aged 70 years and over (999 men, 1033 women) participated.

MAIN RESULTS

Overall, 16% of the elderly live in institutions. The percentage is higher in women and in the older age group (81% for those aged 80 years and over). After adjusting for age and sex, the following factors were positively associated with institutionalisation: poor cognitive function, measures of functional disability, poor vision, Parkinson's disease, stroke, and past fractures. Multivariate analysis identified age and marital status as associated factors with the highest odds ratio (13.6 and 7.1 respectively), followed by various disability indicators.

CONCLUSION

The survey shows that requirements for long term care places are unlikely to be much affected by preventive measures, and would need to increase by about 30% by 2000 to cope with the projected increase in the number of elderly aged 70 years and over. Measures to provide sufficient trained personnel and policy for regulation of standards should be made.

Mortality of frail elderly people living at home in relation to housing conditions

STUDY OBJECTIVE

The study was undertaken to identify any relationship between the mortality of frail elderly people living at home and their housing conditions.

DESIGN AND SETTING

A cohort of frail elderly people living in Yao City, Osaka Prefecture, Japan was followed for six years. Data on demographic variables, activities of daily living, the disease that was the main cause of the disability, medical treatment, the feasibility of continuing family care, and some housing conditions were collected in December 1983 by interview during home visits. Deaths were checked for each year for five years.

SUBJECTS

Altogether 423 people aged 65 years or more living at home in Yao City who were disabled and housebound for at least three months were studied.

MEASUREMENTS AND MAIN RESULTS

Life table analysis and multivariate logistic regression analysis were done. The cumulative survival rates of old people with good housing conditions were higher than those with poor housing conditions in each group stratified by age, sex, or the activities of daily living level. The odds ratio for poor housing conditions compared with good housing conditions for five year mortality remained highly significant after adjustment for potential confounding factors including age, sex, and the activities of daily living level by logistic regression analysis.

CONCLUSIONS

The mortality of frail elderly people living at home is affected by housing conditions. Programmes to improve housing conditions of the disabled are important for home care of the elderly.
