The medical interview: differences between adult and geriatric outpatients.

BACKGROUND: There is a perception that primary care physicians spend less time with older patients and little is known about physician and older patient satisfaction during clinical encounters. OBJECTIVE: To determine how primary care interviews of geriatric patients differ from those of other adults. DESIGN: Descriptive, analytic study. SETTING: Ten primary care sites in the United States and one in Canada, including public, voluntary, and private clinics and practices. PARTICIPANTS: Of the 544 patients, 45.6% were 65 and older and 17.8% were 75 or older. There were 127 participating physicians. MEASUREMENTS: Encounters were audiotaped and analyzed. Patients and physicians also completed exit questionnaires. RESULTS: Interview length increased significantly with age for men but not for women. Physician satisfaction did not change as patient age increased. Patient satisfaction, on the other hand decreased with age among women but not for men. Although physicians' and younger patients' perceptions of health were moderately associated, there was no association for men ages 75 and over. CONCLUSIONS: There is no evidence that physicians spend less time or are more uncomfortable with older patients. Both physician and male patient satisfaction remain stable with increasing patient age, despite greater disparity in patient and physician perceptions of health. Older female patients are less satisfied with physician visits than their younger counterparts, in the absence of changes in interview length or disparities between older female patients and their physicians in health perception.

Physician-older patient communication at the end of life.

Communication with dying patients and their families requires special skills to assist them in this extremely stressful period. This article begins with a case that illustrates many of the challenges of communicating with the dying. It then reviews the literature about communication with older patients at the end of life, focusing on physician-patient discussions, decision-making, advance directives, and cultural factors. The article concludes with a practical discussion of problems that physicians may encounter when working with older patients at the end of life and their families and recommendations to improve communication.

How to get the most benefit from a changing home health care system.

By 1998, a Medicare prospective payment system for home care is expected to be in place. Physicians must become more involved in home care, because they will be held accountable for the patients they refer and the services they order.

Effects of a restraint reduction intervention and OBRA '87 regulations on psychoactive drug use in nursing homes.

OBJECTIVES: To describe the changes in psychoactive drug use in nursing homes after implementation of physical restraint reduction interventions and mandates of the Omnibus Budget Reconciliation Act of 1987 (OBRA '87). METHODS: A secondary analysis was conducted using data from a controlled clinical trial that took place in three nursing homes: a control home, one that received an educational intervention, and one that received an educational/consultation intervention. All three homes were influenced by the OBRA mandates. Complete pre- and 6 months' post-intervention data on use of psychoactive drugs and physical restraints were available for 446 resident subjects. Changes were first analyzed with the resident subjects as the unit of analysis and then using the nursing home ward (n = 16) as the unit of analysis. RESULTS: While physical restraint use declined in the home that received the educational/consultation intervention, neither neuroleptic nor benzodiazepine use increased in any of the homes after the interventions. The percentage of residents taking neuroleptics declined in the control home (18.6% to 11.3%, P = .014). Benzodiazepine use, which was more prevalent than described previously in the literature, declined in all three homes (P < .001). Of those residents whose physical restraints were discontinued, only 2% were started on neuroleptics. When the effect of OBRA mandates on appropriateness of neuroleptic use was examined, the percentage of residents on neuroleptics who lacked an OBRA-approved indication declined from 21.3% to 14.6% in the total sample, and from 39.9% to 8% in the control home. CONCLUSIONS: Interventions to reduce physical restraint did not lead to an increase in psychoactive drug use; further, reduction in both can occur simultaneously. OBRA mandates regarding psychoactive drug use were not uniformly effective, but appear, at minimum, to have increased awareness of the indications for neuroleptics.

Antimicrobial resistance patterns in long term geriatric care. Implications for drug therapy.

There is a high prevalence of bacterial infections in long term care facilities (4.4 to 16.2%). This, together with the fact that antimicrobial resistance is a big concern in current medical practice, makes infection control so important in nursing home care. This article covers the mechanisms of antibacterial resistance and focuses on 4 major antibacterial-resistant bacteria. Vancomycin is the treatment of choice for methicillin-resistant Staphylococcus aureus (MRSA). Colonisation with MRSA is not uncommon in nursing homes and eradication is probably not necessary. Any clinically important enterococcal infection should be tested for high-level resistance. An infectious disease consultation should be sought for vancomycin-resistant enterococcal infections. Gram-negative bacilli have developed multi-resistance. Susceptibility testing can identify the most appropriate therapy. Multiresistance should also be considered when treating Streptococcus pneumoniae. Overall, handwashing is highly recommended. Barrier precautions, minimising hospitalisations and avoiding unnecessary personnel rotation can reduce the chance of resistance spread.

The CARE Program: a nurse-managed collaborative outpatient program to improve function of frail older people. Collaborative Assessment and Rehabilitation for Elders.

BACKGROUND AND OBJECTIVES: Frail older adults are especially vulnerable in a health system that is fragmented and fails to focus on preservation or restoration of function. The School of Nursing at the University of Pennsylvania, together with the School of Medicine and the Hospital of the University of Pennsylvania, established the Collaborative Assessment and Rehabilitation for Elders (CARE) Program to meet the needs of this population. We used the British Day Hospital as a model because it provides a comprehensive approach to care and a bridge between acute, home-based, and institutional long-term care. We have designed our program to provide innovative, interdisciplinary care as well as to be reimbursable under current and future payment structures. This nurse-managed, collaborative practice seeks to maximize independent functioning, promote health, and enhance quality of life for chronically ill, frail older adults living in the community whose needs are left unmet by existing services. The program was certified as a Comprehensive Outpatient Rehabilitation Facility (CORF) in December 1993 to maximize reimbursement of services through Medicare and other third party payers. With a Gerontological Nurse Practitioner as care manager, clients receive an intensive, individualized, time-limited program of nursing, rehabilitation, mental health, social, and medical services in one setting several days each week. Additional geriatric services, such as primary care, are available in the same location when needed. SETTING: The program is housed in renovated space devoted to the care of older people. The academic and clinical offices of the University of Pennsylvania's nursing and medical gerontologic and geriatric faculty are in the same building. PARTICIPANTS: We have targeted those persons older than age 65 who have complex health problems and are living at home. Individuals must need multiple services, including at least one rehabilitation therapy, and they must be unsuitable-for inpatient rehabilitation. DESCRIPTION OF THE POPULATION: In its first 8 months of operation, the program received 97 referrals and admitted 53 clients. Clients were, on average, 78 years of age. Over three-fourths (77%) were women and 58% were black. The average stay in the program was 6 weeks. FIM scores, which improved a mean of 2.4 points, were found to lack sensitivity to the functional improvements achieved by clients. CONCLUSION: Under existing Medicare and third party reimbursement policies, it is feasible to establish a nurse-managed comprehensive outpatient rehabilitation program designed to meet the needs of frail older persons. Preliminary data support the beneficial effects of the program as well as the economic feasibility of this approach.

Risk factors for the development of hyponatremia in psychiatric inpatients.

BACKGROUND: When inpatients who are on psychiatry services develop hyponatremia, medical consultation is usually required for evaluation and management, thus halting or delaying psychiatric treatment. Risk factors for the development of hyponatremia in this population have not been studied. METHODS: A case-control study of psychiatric inpatients in a tertiary care facility was performed. Sixty-four patients who had a serum sodium level of less than 130 mmol/L were identified; three control subjects were chosen from the inpatient psychiatry service for each case. Risk factors investigated included medications, psychiatric diagnoses, basic demographic variables, and medical comorbidities. RESULTS: Univariate and logistic regression analyses revealed that, in addition to diuretic use (adjusted odds ratio, 8.2; 95% confidence intervals, 2.2 to 30.8), use of fluoxetine (adjusted odds ratio, 21.4; 95% confidence interval, 5.3 to 86.9), tricyclic antidepressants (adjusted odds ratio, 4.9; 95% confidence interval, 1.6 to 15.2), and calcium antagonists (adjusted odds ratio, 4.0; 95% confidence interval, 1.1 to 14.2) were all associated with the development of hyponatremia. Important comorbidities included elevated creatinine levels, chronic obstructive pulmonary disease, hypertension, systolic blood pressure, and diabetes. Although age was significantly associated with hyponatremia in univariate analyses, it was not significant in multivariate analyses. CONCLUSIONS: Among psychiatric patients, hyponatremia is often associated with factors other than psychogenic polydipsia, including medications and medical comorbidities. Although elderly psychiatric inpatients seem to develop hyponatremia more often than younger patients, once drugs and comorbidities are taken into account, age does not appear to be a significant risk factor for hyponatremia in this population.

Development of complications during rehabilitation.

BACKGROUND AND METHODS: Although studies have demonstrated that medical rehabilitation patients have many complications that warrant attention, none has attempted to categorize complications by severity. This retrospective cohort study examined the incidence, types, and severity of problems that interrupt rehabilitation and the major risk factors for these events. RESULTS: Of 1075 patients, 359 (33.4%) had acute medical complications on rehabilitation considered severe enough to interrupt treatment. Of the 359 patients, 158 (44%) required an unexpected transfer off rehabilitation. The most common reasons for unexpected transfer were surgical causes (22.8%), followed by infection or fever (17.1%) and by thromboembolic events (16.5%). Logistic regression revealed that major risk factors for complications requiring transfer were a primary diagnosis of deconditioning or nontraumatic spinal cord injury (adjusted odds ratio, 2.7; confidence interval, 1.8 to 4.2), severity of initial disability (adjusted odds ratio, 1.2; confidence interval, 1.1 to 1.3 for every 10-point drop in a Modified Barthel Index), and number of comorbid conditions (adjusted odds ratio, 1.1; confidence interval, 1.0 to 1.2). Risk factors for any complication were similar, but there was an interaction between comorbidity and the degree of functional impairment; in patients who were severely functionally impaired, the number of comorbidities was not as strongly associated with the risk of complications as it was in patients who were less functionally impaired. CONCLUSION: There is a complex relationship among the type of underlying medical impairment, severity of functional limitation, comorbidity, and unanticipated medical or surgical complications that interrupt rehabilitation. The interruptions vary both in type and in severity.

Methicillin-resistant Staphylococcus aureus colonization in a new nursing home.

Methicillin-resistant Staphylococcus aureus (MRSA) has been detected in nursing homes and long-term care facilities. Studies disagree about the risk of infection with MRSA in colonized patients. MRSA colonization and infection were tracked for one year in all admissions to a 60-bed ward at the Philadelphia VA Nursing Home Care Unit (NHCU) from the time of its opening in June, 1990. Patients and staff were blinded to culture results, and the NHCU followed universal precautions for all patients. Of the first 72 patients, 7 were found to be colonized with MRSA; only one of them was known to have had MRSA prior to NHCU transfer. Three patients died (2 had negative cultures prior to death), and 1 was discharged home. Three patients spontaneously cleared MRSA colonization and lived to the end of the study. Three patients appeared to be colonized by MRSA after admission; subsequent cultures were negative. No patients were infected by MRSA in the NHCU. At the close of the study, one year after the nursing home opened, no patient in the nursing home had a culture positive for MRSA. In conclusion, colonization with MRSA at the time of admission to the nursing home is not uncommon, but patients can spontaneously clear it. Besides, nursing homes that pre-screen only those patients with classic risk factors may be admitting many MRSA-colonized patients. Nonetheless, universal precautions appear to be effective in limiting transmission of MRSA in the nursing home; in this study, MRSA acquisition was sporadic and brief.

Collaboration in the preparation of the generalist physician.

Collaborative efforts among health care professionals and institutions at all levels will be essential to the increased production of generalist physicians. There have been many successful collaborations in education and patient care among certifying boards, faculty, physicians in practice, specialists, generalists, and non-physician health professionals, as well as among the three generalist specialties. Recommended strategies to encourage collaboration in the preparation of generalist physicians include: creation of an institutional collaborative curriculum committee; design of a longitudinal curriculum on collaboration for physicians-in-training and other health professionals; implementation of collaborative patient care in ambulatory care teaching clinics; development of integrated systems of care that link inpatient, outpatient, and community-based health services; and education of physicians-in-training in these and other collaborative and co-practice models of patient care.

Prevention and other special management issues in the postacute care of the geriatric stroke patient.

Rehabilitation of older stroke patients does not take place isolated from social and medical problems. Nurses and internists are crucial members of the interdisciplinary team, maintaining health and preventing long- and short-term complications in the stroke survivor. This review describes our research interests and clinical approaches to some of the special medical and nursing needs of the population, using prevention as a model for caring for these chronically ill patients and their families.

Silent ischemia in rehabilitation patients: limited clinical utility of electrocardiographic monitoring.

In a prospective blinded trial, 24-hour continuous electrocardiographic monitoring for silent ischemia was used to try to identify rehabilitation patients at risk for cardiac complications. Five of 42 patients had episodes of silent ischemia, none of which occurred during physical therapy sessions. One of these patients had syncope while wearing the Holter; none of the other four patients had significant cardiac complications during their rehabilitation, and all were discharged home. None of the patients without ischemia on the monitor had complications, but two patients of 14 whose ECGs precluded monitoring for ischemia had complications. In addition, six patients had episodes of nonsustained asymptomatic ventricular tachycardia, 12 had episodes of supraventricular tachycardia, and four had significant ventricular ectopy, all without clinical significance. Despite the apparent high sensitivity and specificity of the technique, the positive predictive value of monitoring eligible patients for silent ischemia was 20%. We conclude that ambulatory electrocardiographic monitoring for silent ischemia or ectopy has limited clinical utility in the rehabilitation population.

Management of stage III pressure ulcers in moderately demented nursing home residents.

PURPOSE: To determine whether the myocutaneous flap procedure, the preferred treatment for young patients with stage III pressure ulcers, is appropriate for moderately demented nursing home residents. SUBJECTS AND METHODS: A model of the treatment decision was created using the decision-tree format. The probabilities of treatment outcomes in the decision tree were derived from the literature. Utilities for treatment outcomes were obtained from five internists, five geriatricians, six nurse practitioners, five plastic surgeons, and six lay people. RESULTS: A majority in each group of respondents favored surgery, according to the decision analysis. Sensitivity analysis showed that surgery was preferred unless its success rate was less than 30%, or the rate of healing with conservative measures was at least 40%, which are unlikely values. Economic analysis demonstrated that surgery was $17,000 more expensive than conservative therapy. CONCLUSION: The myocutaneous flap procedure is preferred by the majority of relevant decision makers when cost is not a consideration. The relative underutilization of surgery in practice has many possible explanations. The most likely are the failure of providers to appreciate the morbidity of pressure ulcers and the reluctance of practitioners to perform expensive procedures on demented patients.
