Improving functional outcomes in older patients: lessons from an acute care for elders unit

BACKGROUND: Hospitalization often marks the beginning, and may be partially responsible for, a downward trajectory characterized by declining function, worsening quality of life, placement in a long term care facility, and death. At the University Hospitals of Cleveland, an Acute Care for Elders (ACE) unit that reengineered the process of caring for older patients (> or = 70 years of age) to improve functional outcomes was established in September 1990. DESCRIPTION OF INTERVENTION: The general principles of ACE included an approach to care guided by the biopsychosocial model and recognition of the importance of fitting the hospital environment to the patient's needs. The design of the intervention was consistent with principles of comprehensive geriatric assessment and continuous quality improvement. Care, which focused on maintaining function, was directed by an interdisciplinary team that considered the patient's needs both at home and in the hospital. The major components of the ACE Unit intervention included patient-centered nursing care (daily assessment of functional needs by nursing, nursing-based protocols to improve outcomes, daily rounds by a multidisciplinary team), a prepared environment, planning for discharge, and medical care review. RESULTS: In a randomized trial comparing ACE with usual care, patients receiving ACE had improved functional outcomes at discharge. The costs to the hospital for ACE unit care were less than for usual care. The functional status of ACE and usual care patients was similar 90 days after discharge. FUTURE DIRECTIONS: The ACE unit intervention is being expanded to preserve the improvements observed during the hospitalization in the outpatient setting. In addition, needs other than function which are critical to patients' long-term quality of life are being considered.     

Randomised trial of home-based psychosocial nursing intervention for patients recovering from myocardial infarction

BACKGROUND: Increases in life stress have been linked to poor prognosis, after myocardial infarction (MI). Previous research suggested that a programme of monthly screening for psychological distress, combined with supportive and educational home nursing interventions for distressed patients, may improve post-MI survival among men. Our study assessed this approach for both men and women. We aimed to find out whether the programme would reduce 1-year cardiac mortality for women and men. METHODS: We carried out a randomised, controlled trial of 1376 post-MI patients (903 men, 473 women) assigned to the intervention programme (n = 692) or usual care (n = 684) for 1 year. All patients completed a baseline interview that included assessment of depression and anxiety. Survivors were also interviewed at 1 year. FINDINGS: The programme had no overall survival impact. Preplanned analyses showed higher cardiac (9.4 vs 5.0%, p = 0.064) and all-cause mortality (10.3 vs 5.4%, p = 0.051) among women in the intervention group. There was no evidence of either benefit or harm among men (cardiac mortality 2.4 vs 2.5%, p = 0.94; all-cause mortality 3.1 vs 3.1%, p = 0.93). The programme's impact on depression and anxiety among survivors was small. INTERPRETATION: Our results do not warrant the routine implementation of programmes that involve psychological-distress screening and home nursing intervention for patients recovering from MI. The poorer overall outcome for women, and the possible harmful impact of the intervention on women, underline the need for further research and the inclusion of adequate numbers of women in future post-MI trials.     

Hospital-based advanced home-care, models from Eken?s, Finland

In 1995, advanced home treatment services were introduced at V?stra Nyland district hospital in Finland. For selected patients the new services constitute an alternative where hospitalisation would otherwise be necessary. Some of the hospital bed resources were moved to the patients' homes together with a trained team with immediate responsibility for the patients and providing 24-hour care, backed up by access to hospital resources in terms of specialised knowledge and sophisticated technology. Two years' experience of 500 patients so treated showed their diseases to have represented the complete spectrum of specialists fields. The most common diagnoses were oncological and infectious diseases. Although preliminary assessment suggests advanced home care to be a cheaper alternative than hospitalised care, the preeminent advantage from the patients' point of view was improved quality of life.     

The association between the quality of inpatient care and early readmission: a meta-analysis of the evidence

OBJECTIVES: To help resolve the current controversy over the validity of early readmission as an indicator of the quality of care, the authors critically reviewed the literature using meta-analysis to derive summary estimates of effect and evaluate inter-study heterogeneity. METHODS: The authors selected reports meeting five criteria: (1) presentation of new data on medical-surgical hospitalization of adults; (2) measurement of outcome as a person-specific readmission; (3) readmission within < or = 31 days; (4) examination of some aspect of the process of inpatient care; (5) inclusion of a comparison group. One meta-analysis examined 13 comparisons of readmission rates after substandard versus normative care, another examined 9 comparisons of readmission rates after normative versus exceptional care, and the third examined all 22 comparisons together. Two authors applied inclusion criteria and extracted data on methods and findings. Two others classified studies on 11 methodological variables for the heterogeneity evaluation. RESULTS: The summary odds ratio for readmission after substandard care was 1.24 (0.99-1.57) relative to normative care; for readmission after normative care the summary odds ratio was 1.45 (0.90-2.33) relative to exceptional care. The individual odds ratios varied significantly (chi2, 21 df = 50.34, P = 0.0003). Most of the variance in study odds ratios could be explained by whether the study focused on the quality of patient care or the qualifications of patient care providers. The summary odds ratio for the 16 homogeneous comparisons focusing on the quality of patient care was 1.55 (1.25-1.92). CONCLUSIONS: Early readmission is significantly associated with the process of inpatient care. The risk of early readmission is increased by 55% when care is of relatively low quality, that is, substandard or normative instead of normative or exceptional.     

Controlled trial evaluation of an asthma education programme for adults

BACKGROUND: To improve asthma control and reduce readmission rates through increased knowledge and the development of self management skills, a brief (three hour) adult education programme was developed. METHODS: The course was designed to improve inhaler skills and to teach how to adjust drug doses according to peak flow (PEF) measurements and a treatment plan. It was evaluated in a randomised controlled trial in 76 patients admitted to hospital for asthma by using questionnaires, spirometry, and home monitoring of PEF at entry and at five and 10 months after intervention. The questionnaire provided measures of knowledge about asthma, self management behaviour appropriate to asthma control, asthma symptom frequency and severity, and psychosocial disturbance attributable to asthma. RESULTS: During the 10 months observation period the readmission rate for the educated group was one seventh that of the control group and attendance at accident and emergency departments also decreased. No consistent differential improvements were observed in spirometric results, average PEF, or mean daily variability of PEF. Both groups showed improvements in measures of asthma knowledge, behaviour, symptoms, and psychosocial disturbances. However, the intervention group showed a significantly greater improvement in some measures of asthma knowledge and self management skills. CONCLUSION: Despite minimal effect on measures of airway function, substantial changes in illness behaviour and use of health care facilities can be achieved by a brief asthma education programme.     

Rehabilitation after myocardial infarction or coronary surgery: elderly patients may benefit as much as the younger ones

At most Swedish hospitals participation in cardiac rehabilitation programmes is restricted to patients of working age, although coronary patients predominately belong to the higher age groups. The article consists in a review of the benefits of cardiac rehabilitation to the elderly, such as enhanced quality of life and lower readmission rates, improvement in co-ordination, muscular strength and bone mineral constant, and a cardioprotective effect on risk factors. Cardiac rehabilitation programmes for the elderly, preferably organised in close so-operation between local hospitals, primary care facilities and patient organisations, might yield considerable individual and general health economic benefits.     

Exercise training in COPD patients: the basic questions

Pulmonary rehabilitation programmes aim at improving exercise capacity, activities of daily living, quality of life and perhaps survival in patients with chronic obstructive pulmonary disease (COPD). Recently, well-designed studies investigated and confirmed the efficacy of comprehensive pulmonary rehabilitation programmes, including exercise training, breathing exercises, optimal medical treatment, psychosocial support and health education. In the present overview, the contribution of exercise training in clinical practice to the demonstrated effects of pulmonary rehabilitation is discussed by means of six basic questions. These include: 1) the significance of exercise training; 2) the optimal intensity for exercise training; 3) prescribing training modalities; 4) the effects of exercise training combined with medication, nutrition or oxygen; 5) how training effects should be maintained; and 6) where the rehabilitation programme should be performed: in-patient, out-patient or homecare? First, exercise training has been proven to be an essential component of pulmonary rehabilitation. Training intensity is of key importance. High-intensity training (>70% maximal workload) is feasible even in patients with more advanced COPD. In addition, the effects on peripheral muscle function and ventilatory adaptations are superior to low-intensity training. There is, however, no consensus on the optimal training modalities. Both walking and cycling improved exercise performance. Since peripheral muscle function has been recognized as an important contributor to exercise performance, specific peripheral muscle training recently gained interest. Improved submaximal exercise performance and increased quality of life were found after muscle training. The optimal training regimen (strength or endurance) and the muscle groups to be trained, remain to be determined. Training of respiratory muscles is recommended in patients with ventilatory limitation during exercise. The additional effects of anabolic-androgenic drugs, oxygen and nutrition are not well-established in COPD patients and need further research. In order to maintain training effects, close attention of the rehabilitation team is required. The continuous training frequency necessary to maintain training effects remains to be defined. At this point in time, out-patient-based programmes show the best results and guarantee the best supervision and a multidisciplinary approach. Future research should focus on the role of homecare programmes to maintain improvements.     

Quality assurance programme for nursing

This article describes a conceptual and methodological framework for evaluating nursing care quality. The conceptual framework is based on Orem's theory of self-care which emphasizes the importance of decisions in the selection of nursing process based on patient status and problems. The primary outcome criteria is self-care. The methodological framework is based on Greenfield's criteria maps methodology for linking patient status (problems or diagnoses) to decisions about nursing interventions and linking these specific nursing intervention criteria to desired outcomes for self-care. The article further describes a multiagency quality assurance programme for nursing. The programme includes: a definition of criteria and standards across agencies; nursing care management protocols that define standards of care; continuing education courses for nursing based on management protocols; the maps method of auditing actual and recorded nursing process and patient outcomes as defined in the management protocol.     

The role of psychiatric comorbidity in the prediction of readmission for detoxification

BACKGROUND: The burden of caring for terminal cancer patients has a negative effect on the informal caregivers' quality of life. OBJECTIVES: To investigate the effects of a transmural home care intervention program for terminal cancer patients on the direct caregivers' (the patient's principal informal caregiver) quality of life, compared with standard care programs. The intervention program intended to optimize the cooperation and coordination between the intramural and extramural health care organizations (transmural care). METHODS: Direct caregivers of terminal cancer patients (estimated prognosis of less than 6 months) could be included in this quasi-experimental study. The direct caregivers' quality of life was measured in a multidimensional way 1 week before (T1), 1 week after (T2), and 4 weeks after (T3) the patient's discharge from the hospital (discharge being the starting point of the intervention), then again at 3 months after the patient's death (T4). Factor analyses on the four outcome measures yielded one factor. This was considered the primary outcome measure and was named the Overall Quality of Life Index (OQOLI). RESULTS: Multiple regression analyses showed that the intervention contributed significantly positively to the direct caregivers' OQOLI at T2 (beta=.30; p < .05) and T4 (beta=.28; p < or = .05), compared with standard care. CONCLUSION: Transmural care forms a significantly positive contribution to the OQOLI of direct caregivers of terminal cancer patients 1 week after the patient's discharge from the hospital and 3 months after the patient's death. Good terminal care also appears to be important for direct caregivers as well, with respect to perceived quality of life.     

Evaluation of a palliative care service: problems and pitfalls

OBJECTIVE: To evaluate a palliative care home support team based on an inpatient unit. DESIGN: Randomised controlled trial with waiting list. Patients in the study group received the service immediately, those in the control group received it after one month. Main comparison point was at one month. SETTING: A city of 300,000 people with a publicly funded home care service and about 200 general practitioners, most of whom provide home care. MAIN OUTCOME MEASURES: Pain and nausea levels were measured at entry to trial and at one month, as were quality of life for patients and care givers' health. RESULTS: Because of early deaths, problems with recruitment, and a low compliance rate for completion of questionnaires, the required sample size was not attained. CONCLUSION: In designing evaluations of palliative care services, investigators should be prepared to deal with the following issues: attrition due to early death, opposition to randomisation by patients and referral sources, ethical problems raised by randomisation of dying patients, the appropriate timing of comparison points, and difficulties of collecting data from sick or exhausted patients and care givers. Investigators may choose to evaluate a service from various perspectives using different methods: controlled trials, qualitative studies, surveys, and audits. Randomised trials may prove to be impracticable for evaluation of palliative care.     

Tetanus: critical implications for nursing

In the United States today, tetanus is a rare disease. However, when it occurs, it can be a highly challenging situation for all members of the healthcare team. The majority of care during the course of the disease is supportive. The availability of personnel trained in managing cardiorespiratory emergencies and sustained mechanical ventilation in the ICU environment can have a beneficial effect on patients' outcomes. An awareness of the potential complications of tetanus can hasten recovery and maintain the patient's preexisting quality of life.     

Diminished hyperaemic response of the hepatic artery to portal venous occlusion (the buffer response) in Asian hybrid minipigs: a comparison of the response to that observed in dogs

This study is part of a larger study of the effect of integrity-promoting care in a Swedish nursing home ward. Compared with assessments on a control ward, improvements were found in the patients' behaviour and in the quality of care after a three-month intervention period. This paper reports on parts of a questionnaire survey on the nursing staff's opinions of their working conditions and demented patients. Most staff members on both the intervention ward and the control ward found their jobs meaningful, engaging and stimulating, but they also felt that they had a heavy work-load. Most of the staff members experienced mental strain because of the patients' disturbed behaviour. Many did not think that the care on their ward would have been good enough for their own close relatives, if they had been suffering from dementia. Only slight changes were found in the staff members opinions after the intervention.     

Effects of an intervention by a diabetes team in hospitalized patients with diabetes

OBJECTIVE: Hospitalized patients with diabetes have a prolonged length of stay in the hospital. We conducted a controlled prospective randomized feasibility study of the effects of a diabetes team (a diabetes nurse educator and an endocrinologist) on the length of stay and other outcomes of hospitalization in these patients. RESEARCH DESIGN AND METHODS: A total of 179 hospitalized patients with diabetes were randomly assigned to receive usual care supplemented with (85 patients) or without (94 control patients) a diabetes team intervention. Outcome measures included the length of stay, blood glucose control, and rates of readmission. RESULTS: For the primary diagnosis of diabetes, the median length of stay was 5.5 days (95% CI 4-8 days) for patients who received diabetes team intervention and 7.5 days (5-11 days) for the control patients (NS). For the secondary diagnosis of diabetes, the median length of stay was 10.0 days (8-13 days) in the intervention group and 10.5 days (8-13 days) in the control group (NS). One month after the team intervention was initiated, 75% of patients in the intervention group were in good glycemic control, compared with 46% in the control group. Readmissions at 3 months after discharge included 13 (15%) patients from the intervention group and 30 (32%) patients in the control group (P = 0.01). CONCLUSIONS: Randomized controlled prospective trials of clinical interventions in hospitalized patients with diabetes are feasible. Diabetes team intervention appears to reduce the hospital length of stay and to improve glycemic control. Team intervention significantly reduces the rate of recurrent hospitalization.     

Are preventive measures against suicide efficient? A literature review

The increasing frequency of suicide in Norway from 1970 to 1990 has called attention. This paper raises the question of whether any controlled studies have been conducted on prevention of suicide. A search was made in Medline; the criteria for including articles were: controlled studies concerning the effects of suicide-preventive intervention by measuring the number of suicides, parasuicides or suicidal thoughts/ideation. The result of our search was 13 randomised controlled trials and two case-control studies. Most of the studies were unable to confirm any effect of suicide-preventive intervention. In most studies the experiment and control groups were far too small to arrive at significant conclusions. Prior to starting prevention programmes, it is necessary for the health service to know the potential effects. This systematic review revealed that few good controlled studies have been conducted on suicide prevention. For the time being we have to accept the suggestive evidence for certain types of intervention, and use these as a basis for action.     

Painless dentistry. Fact or fiction?

The complex chronic health problems and functional limitations common in the elderly population place them at risk for complicated hospitalizations and discharge planning. The purpose of this study was to investigate the effectiveness of a discharge planning protocol in identifying elderly patients' home care needs. The sample in this quasiexperimental study consisted of 507 hospitalized patients age 65 years or older. The control group received the usual hospital discharge planning protocol. In the experimental group, nurse/social worker teams coordinated the discharge planning process, using an adapted form of the Discharge Planning Questionnaire (DPQ) to identify the home care needs of elderly patients. Thirty days after hospital discharge, both patient groups participated in a telephone survey to obtain information about health care problems they experienced during home recovery and their use of health care resources. The findings indicated that the majority of the elderly patients had functional dependencies, which required the help of another person to carry out daily household duties and provide assistance with basic needs, especially ambulation. These functionally dependent patients only received home care referrals about 50% of the time. These findings raise questions about current reimbursable services. Logistic regression analysis indicated that patients with increased functional dependency and patient problems during home recovery had a greater likelihood of rehospitalization and emergency department usage. This information about the home care of elderly patients after hospitalization supports the need for comprehensive functional assessment as part of discharge planning. This study also suggests that the nurse/social worker team can provide effective screening and discharge planning coordination of home care. Physician involvement and effective communication networks must be in place.     

Randomised trial of impact of model of integrated care and case management for older people living in the community

OBJECTIVE: To evaluate the impact of a programme of integrated social and medical care among frail elderly people living in the community. DESIGN: Randomised study with 1 year follow up. SETTING: Town in northern Italy (Rovereto). SUBJECTS: 200 older people already receiving conventional community care services. INTERVENTION: Random allocation to an intervention group receiving integrated social and medical care and case management or to a control group receiving conventional care. MAIN OUTCOME MEASURES: Admission to an institution, use and costs of health services, variations in functional status. RESULTS: Survival analysis showed that admission to hospital or nursing home in the intervention group occurred later and was less common than in controls (hazard ratio 0.69; 95% confidence interval 0.53 to 0.91). Health services were used to the same extent, but control subjects received more frequent home visits by general practitioners. In the intervention group the estimated financial savings were in the order of 1125 ($1800) per year of follow up. The intervention group had improved physical function (activities of daily living score improved by 5.1% v 13.0% loss in controls; P<0.001). Decline of cognitive status (measured by the short portable mental status questionnaire) was also reduced (3.8% v 9.4%; P<0.05). CONCLUSION: Integrated social and medical care with case management programmes may provide a cost effective approach to reduce admission to institutions and functional decline in older people living in the community.
