The Patient Care Notebook: quality improvement on a rehabilitation unit.

BACKGROUND: Shortened lengths of stay in acute and rehabilitation hospitals, continuing financial pressures on all postacute care services, and increasing out-of-pocket health care costs for patients and families challenge rehabilitation hospitals' patient education and discharge planning processes. Spaulding Rehabilitation Hospital (Boston) introduced a patient care notebook in a 15-bed satellite unit and pilot tested its contribution to the patient education and discharge planning process. DEVELOPING THE NOTEBOOK: The three-ring binder notebook included sections on medical appointments and phone numbers, understanding illness and medical care, coping with illness, physical activities, recommendations for the home, and community resources, with both standard and patient-specific information. RESULTS: Most of the patients and caregivers who received the notebooks found them to be helpful, and most staff indicated that the notebook improved the teaching process. Telephone calls to the unit after home discharges decreased form 28 calls for 11 discharges to 6 calls for 21 discharges after the notebook began to be used regularly. DISCUSSION: Staff felt that the process of using the notebook helped focus attention on teaching during the entire course of a patient's hospitalization rather than just a day or two before discharge. The patient care notebook process is being introduced to the entire hospital and to all patients, regardless of discharge location and the patient's literacy or proficiency with English. CONCLUSION: In using the notebook, the QI team, and the entire unit staff, learned about the complexities of QI, patient education, and discharge planning. The notebook process was implemented throughout the hospital a little more than a year after the completion of the pilot project.

Applying the domain management model in treating patients with chronic diseases.

BACKGROUND: In the health care system in the United States, the management of chronic health conditions and their functional consequences challenge and frustrate patients, caregivers/families, health care providers, and physicians. Contributing factors include a lack of physician and health care provider training and a health system that emphasizes diagnosis and management of acute illnesses. A broader patient care model is required for patients with chronic disease(s). USING THE DOMAIN MANAGEMENT MODEL (DMM) TO CLASSIFY PATIENTS' CLINICAL PROBLEMS: The DMM is a synthesis of approaches used in internal medicine, geriatric medicine, and physical medicine and rehabilitation. All clinical problems, their treatments, and their outcomes can be classified and followed over time in a multiaxial model with four domains-medical/surgical issues, mental status/emotions/coping, physical function, and living environment. APPLICATIONS OF THE DMM IN MEDICAL RECORD TEMPLATES: Use of the four domain headings in standard templates can lead to an improved awareness of all the relevant issues in the management of chronic illnesses. This awareness precedes a physician's implementation of better care processes. Also, good patient care decisions require good information. MANAGEMENT OF FUNCTIONAL PROBLEMS: The DMM can be used to educate care providers and organize care in terms of important and common functional problem (for example, trouble walking, which lacks a standard approach in health care). CONCLUSION: This common framework for the organization, documentation, and communication of patients' care over time will help teach systematic mangement of chronic health conditions and help with future research on complex patient management.

Mobility difficulties are not only a problem of old age.

BACKGROUND: Lower extremity mobility difficulties often result from common medical conditions and can disrupt both physical and emotional well-being. OBJECTIVES: To assess the national prevalence of mobility difficulties among noninstitutionalized adults and to examine associations with demographic characteristics and other physical and mental health problems. DESIGN: Cross-sectional survey using the 1994-1995 National Health Interview Survey-Disability Supplement (NHIS-D). We constructed measures of minor, moderate, and major lower extremity mobility difficulties using questions about ability to walk, climb stairs, and stand, and use of mobility aids (e.g., canes, wheelchairs). Age and gender adjustment used direct standardization methods in Software for the Statistical Analysis of Correlated Data (SUDAAN). PARTICIPANTS: Noninstitutionalized, civilian U.S. residents aged 18 years and older. National Health Interview Survey sampling weights with SUDAAN provided nationally representative population estimates. RESULTS: An estimated 19 million people (10.1%) reported some mobility difficulty. The mean age of those with minor, moderate, or major difficulty ranged from 59 to 67 years. Of those reporting major difficulties, 32% said their problems began at aged 50 years or younger. Adjusted problem rates were higher among women (11.8%) than men (8.8%), and higher among African American (15.0%) than whites (10.0%). Persons with mobility difficulties were more likely to be poorly educated, living alone, impoverished, obese, and having problems conducting daily activities. Among persons with major mobility difficulties, 30.6% reported being frequently depressed or anxious, compared to 3.8% for persons without mobility difficulties. CONCLUSIONS: Reports of mobility difficulties are common, including among middle-aged adults. Associations with poor performance of daily activities, depression, anxiety, and poverty highlight the need for comprehensive care for persons with mobility problems.

A randomized controlled trial of exercise to improve outcomes of acute hospitalization in older adults.

OBJECTIVE: Older adults hospitalized for nondisabling diagnoses can lose functional ability. Lack of exercise or physical activity during the acute illness and recovery may be contributory. This study evaluated whether increased exercise in hospital and afterward would shorten length of stay and improve physical function at 1 month. DESIGN: A randomized controlled trial. SETTING: A 700-bed community-based hospital with academic and teaching programs. PARTICIPANTS: Three hundred patients (mean age 78.2 years +/- 5.6) with nondisabling medical and surgical diagnoses who were admitted to an acute care hospital between December 1990 and April 1992. All patients had an expected length of stay 5 or more days, were ambulatory before admission, and were not expected to die within 12 months. INTERVENTION: A hospital-based general exercise program was administered to intervention patients along with encouragement to continue the program, self-administered, at home. MEASUREMENTS: The primary outcome was hospital length of stay. Secondary outcomes at 1 month post-discharge included measures of physical function and other general health indicators. RESULTS: There was no significant difference in length of stay between treatment and control groups controlling for baseline characteristics and diagnoses. The intervention was associated with better function in instrumental activities of daily living (beta = .433 (95% CI, 0.044-0.842)) at 1 month but no change in perceived general health status and other measures of physical function. CONCLUSIONS: An exercise program started during hospitalization and continued for 1 month did not shorten length of stay but did improve functional outcome at 1 month.

Mobility problems and perceptions of disability by self-respondents and proxy respondents.

BACKGROUND: The Americans With Disabilities Act defines disability on the basis of physical or mental impairments or external perceptions of impairment. OBJECTIVES: The objective of this study was to examine perceptions of disability among people with lower-extremity mobility difficulties. RESEARCH DESIGN: This study used a cross-sectional, nationally representative survey, the 1994 to 1995 National Health Interview Survey-Disability (NHIS-D) supplement. Using SAS-callable SUDAAN for all analyses, we produced national population estimates. SUBJECTS: This study included 142,572 noninstitutionalized, civilian residents of the United States who were > or =18 years of age, with 80,423 self-respondents and 49,883 proxy respondents. MEASURES: We created a 4-level mobility variable using NHIS-D questions about the ability to walk, climb stairs, stand and the use of mobility aids. We examined associations between mobility and answers to 2 questions about self- and external perceptions of disability. RESULTS: The results showed that 3.1% (estimated 5.82 million persons) reported major mobility difficulties, including 3.7% of self-respondents and 2.7% of those with proxy respondents. Among persons with major mobility problems, 70.8% perceived themselves as disabled, whereas 64.8% thought other people see them as disabled. Also, 80.5% of manual wheelchair users saw themselves as disabled. Proxies were somewhat more likely to perceive disability than self-respondents, although differences were not generally statistically significant. In multivariable regressions, mobility level was the strongest predictor of self-perceived disability, followed by general health status. CONCLUSIONS: Mobility problems increase the likelihood that people will see themselves as disabled, but these perceptions are not universal. Although the schematic of wheelchair users has become an international symbol of disability, many people with serious mobility problems do not view themselves as disabled.

Mobility impairments and use of screening and preventive services.

OBJECTIVES: Primary care for people with disabilities often concentrates on underlying debilitating disorders to the exclusion of preventive health concerns. This study examined use of screening and preventive services among adults with mobility problems (difficulty walking, climbing stairs, or standing for extended periods). METHODS: The responses of non-institutionalized adults to the 1994 National Health Interview Survey, including the disability and Healthy People 2000 supplements, were analyzed. Multivariable logistic regressions predicted service use on the basis of mobility level, demographic characteristics, and indicators of health care access. RESULTS: Ten percent of the sample reported some mobility impairment; 3% experienced major problems. People with mobility problems were as likely as others to receive pneumonia and influenza immunizations but were less likely to receive other services. Adjusted odds ratios for women with major mobility difficulties were 0.6 (95% confidence interval [CI] = 0.4, 0.9) for the Papanicolaou test and 0.7 (95% CI = 0.5, 0.9) for mammography. CONCLUSIONS: More attention should be paid to screening and preventive services for people with mobility difficulties. Shortened appointment times, physically inaccessible care sites, and inadequate equipment could further compromise preventive care for this population.

Hospital admission risk profile (HARP): identifying older patients at risk for functional decline following acute medical illness and hospitalization.

OBJECTIVES: To develop and validate an instrument for stratifying older patients at the time of hospital admission according to their risk of developing new disabilities in activities of daily living (ADL) following acute medical illness and hospitalization. DESIGN: Multi-center prospective cohort study. SETTING: Four university and two private non-federal acute care hospitals. PATIENTS: The development cohort consists of 448 patients and the validation cohort consists of 379 patients who were aged 70 and older and who were hospitalized for acute medical illness between 1989 and 1992. MEASUREMENTS: All patients were evaluated on hospital admission to identify baseline demographic and functional characteristics and were then assessed at discharge and 3 months after discharge to determine decline in ADL functioning. RESULTS: Logistic regression analysis identified three patient characteristics that were independent predictors of functional decline in the development cohort: increasing age, lower admission Mini-Mental Status Exam scores, and lower preadmission IADL function. A scoring system was developed for each predictor variable and patients were assigned to low, intermediate, and high risk categories. The rates of ADL decline at discharge for the low, intermediate, and high risk categories were 17%, 28%, and 56% in the development cohort and 19%, 31%, and 55% in the validation cohort, respectively. Patients in the low risk category were significantly more likely to recover ADL function and to avoid nursing home placement during the 3 months after discharge. CONCLUSION: Hospital Admission Risk Profile (HARP) is a simple instrument that can be used to identify patients at risk of functional decline following hospitalization. HARP can be used to identify patients who might benefit from comprehensive discharge planning, specialized geriatric care, and experimental interventions designed to prevent/reduce the development of disability in hospitalized older populations.

Hip replacement and hip hemiarthroplasty surgery: potential opportunities to shorten lengths of hospital stay.

The potential safety and effectiveness of a practice guideline recommending a 5-day postoperative stay in the acute care hospital for hip surgery patients without clinical findings predictive of a complicated hospital course was studied retrospectively in 230 patients hospitalized for total hip replacement, total hip replacement with osteotomy, or hip hemiarthroplasty. Seventy percent of total hip replacement and hip hemiarthroplasty patients were classified as being at "low risk" for complications by the guideline (161 patients, or 73% of patients who remained hospitalized). Use of the guideline could have reduced the hospital length of stay from 8.4 days (standard deviation 3.3) to 5.9 days for these selected low-risk patients. Moreover, physicians' implicit review determined that 0% of patients (95% confidence interval, 0% to 2.3%) had a complication that would have benefited from continued stay in an acute care hospital after the fifth postoperative day. Our practice guideline may have the potential to safely reduce acute care hospital length of stay for patients recovering after total hip replacement and hip hemiarthroplasty. The guideline will require further study in a prospective clinical trial before it can be recommended for widespread use.

Surrogate decision-makers' satisfaction with the placement of feeding tubes in elderly patients.

OBJECTIVE: To assess the satisfaction of surrogate decision-makers with the decision to place feeding tubes in elderly patients with impaired decision-making capacity. DESIGN: Inception cohort followed for 5 weeks. SETTING: Four hospitals in the greater Los Angeles area. PARTICIPANTS: Fifty-eight surrogate decision-makers for elderly patients (over 60) who recently received a first-time percutaneous endoscopic gastrostomy. Participants were identified through the endoscopy departments at the four hospitals. MEASUREMENTS: We surveyed surrogates by telephone within 5 days of placement for background data and after 5 weeks of use to assess satisfaction with the decision. The main outcome variables at follow-up were: surrogate satisfaction; whether the surrogate would repeat the decision; whether the surrogate had considered removal of the tube; and surrogates' perception of patients preference for the tube. RESULTS: After 5 weeks of use, 84% of surrogates stated that they would repeat the decision. Fifty-nine percent of surrogates described themselves as satisfied with the decision, and 17% were dissatisfied. Only 10% had considered removing the tube. After 5 weeks of use, 36% of surrogates felt that the patient would prefer the tube, and 31% felt they would not. CONCLUSIONS: Most surrogates we studied would repeat the decision to have a feeding tube after experiencing its effects for 5 weeks. However, almost one-third felt the patient would not want the tube. Physicians and surrogates may need to place greater emphasis on patients' wishes before placing feeding tubes and when reassessing their benefit to the patient after being placed.

Gait disorders in adults: a classification for their differential diagnosis.

The increasing frequency and prevalence of functionally significant gait disorders in adults requires that more physicians become familiar with systematic assessment and treatment approaches. The classification system presented can help physicians organize their observations and their clinical management of patients with gait problems.

Mobility disorders in older adults: the role of deconditioning.

Deconditioning is a prevalent problem in our sedentary society and is increasingly contributing to functional mobility problems in older adults. Information about exercise and appropriate exercise programs are increasingly available. Physicians and other health care professionals should identify when deconditioning is contributing to a patient's mobility problem and then assist the patient in developing a new exercise habit.

Poor predictive value of hematocrit and hemodynamic parameters for erythrocyte deficits after extensive elective vascular operations.

Fluid resuscitation and transfusion therapy are particularly critical in patients undergoing extensive vascular operations because of diffuse atherosclerosis and the risk of perioperative myocardial infarction. Sophisticated perioperative monitoring has reduced the mortality rate substantially, but indications for transfusion remain controversial. We determined erythrocyte volume, (EV), total blood volume (TBV) and plasma volume (PV) preoperatively and 18 to 24 hours postoperatively in 41 elderly patients (68.8 +/- 1.3 years) undergoing elective vascular operations (30 abdominal aortic aneurysmorrhaphy, ten aortofemoral bypass and one carotid endarterectomy). EV was measured using 51chromium-labeled autologous erythrocytes; TBV and PV were calculated from EV and total body hematocrit (peripheral venous hematocrit [HCT] x 0.89). Ideal blood volumes were calculated from nomograms based on body surface area and gender. Relationships between body volumes (percentage of ideal), simultaneously measured peripheral venous HCT and hemodynamic parameters heart rate, mean arterial pressure, central venous pressure, pulmonary capillary wedge pressure, cardiac index and systemic vascular resistance index were studied by stepwise regression. In 24 patients, blood volumes and hemodynamic parameters were also measured in the recovery room. HCT significantly correlated with EV at all three time periods (p less than 0.001), but the ability of HCT to predict EV in an individual patient was relatively poor (r = 0.50 preoperatively; r = 0.54 in recovery room and r = 0.66 24 hour postoperatively). By 24 hours postoperatively, EV had decreased to 78.3 +/- 2.4 percent of ideal EV (range of 47 to 112 percent). However, only two patients had HCT less than 30 despite the fact that 13 of 41 patients had an EV deficit of greater than 30 percent. No patient had a HCT of less than 25 percent. Hemodynamic parameters did not contribute to the prediction of EV, PV or TBV at any time. Two patients had myocardial infarctions postoperatively associated with 24 hour EV deficits of 18.5 and 29.6 percent. One patient died of a pulmonary embolus. Because of these findings, the concept of a "transfusion trigger" must be viewed with caution, since many patients undergoing vascular operations will have considerable EV deficits despite an "acceptable" HCT.

Correlates and consequences of eating dependency in institutionalized elderly.

Loss of independent eating capacity is a major problem for the institutionalized elderly. Few studies have examined the factors associated with loss of functional eating capacity. The authors cross-sectionally studied 240 residents of a skilled nursing facility, classified their functional eating status, identified correlated deficits, and followed these residents for six months. Information was gathered through questionnaires, chart review, and physical examinations. Residents were stratified into independent (68%, N = 164) and dependent (32%, N = 76) eating status groups according to the need for physical assistance during meals. Dependency status did not correlate with age (P = .88) or weight loss (P = .27). Loss of independence in eating was associated with impaired mobility (P = .0001), impaired cognition (P = .0001), modified consistency diets (P = .0001), upper extremity dysfunction (P = .0001), abnormal oral-motor examinations (P = .0002), absence of teeth and dentures (P = .002), behavioral indicators of abnormal oral and pharyngeal stages of swallowing (P = .0001), and increased mortality within six months (P = .0001). Eating dependency is therefore associated with multiple impairments and early mortality.

Neutrophil-mediated antibody-dependent killing of herpes-simplex-virus-infected cells.

The ability of neutrophils to serve as effectors of antibody-dependent cell-mediated cytotoxicity (ADCC) was studied using herpes-simplex-virus-infected (HSV-infected) human embryonic lung cells as targets. Killing of infected cells by neutrophils required HSV-immune serum and did not take place in the presence of nonimmune serum or in the absence of serum. Uninfected cells were not killed. ADCC was evident by 30 min and reached a value of 66% by 4 hr at an effector:target ratio of 100:1. Cells from patients with chronic granulomatous disease were as effective as normal cells, and this indicates that ADCC could be mediated by processes that are independent of the respiratory burst.
