Variability in performance of timed walk tests in pulmonary rehabilitation programs.

STUDY OBJECTIVE: To describe variability in the conduct of walk tests in pulmonary rehabilitation programs. DESIGN: : Analysis of information obtained by means of a structured written questionnaire. SETTING: Outpatient pulmonary rehabilitation programs in the United States and Canada. PARTICIPANTS: Clinical coordinators of 75 pulmonary rehabilitation programs. INTERVENTIONS: None RESULTS: Timed walk tests were obtained in 71 of 99 programs surveyed. Considerable variability in all aspects of testing practices was evident. Fifty-seven respondents (80%) based results on a single walk. Walk tests were completed in a hallway (73%), on a walking track (9%), and on a treadmill (7%). In 29 programs (44%), a walk supervisor carried or pulled the oxygen source, while in 25 programs (38%), the oxygen was carried or pulled by the patient. Informal nonstandardized instructions were provided to patients prior to walking in 41 programs (58%). In 53 programs (76%), the walk supervisor could direct a patient to speed up, to slow down, or to rest. Evaluations of breathlessness and perceived exertion were measured during the walk by 73% and 16% of programs, respectively. CONCLUSIONS: Practices regarding performance of timed walk tests are poorly standardized among pulmonary rehabilitation programs. Further research is needed to evaluate the impact of certain variations in testing practices on test results.

Lung volume reduction surgery: an analysis of hospital costs.

OBJECTIVE: Lung volume reduction surgery (LVRS) represents a potential breakthrough in the management of advanced emphysema, although questions remain about clinical and economic implications of widespread application of LVRS. In this report, we describe hospital costs, excluding physicians' fees, for LVRS. DESIGN: Hospital charges were obtained from billing records and converted to costs by applying multiple cost-to-charge ratios. SETTING: A large, urban academic medical center. PATIENTS: Fifty-two consecutive patients who received bilateral LVRS through a median sternotomy between April 1995 and August 1996. RESULTS: Median hospital stay was 10 days (mean= 14.8+/-12.8 days; range=3 to 48 days), including 2 days (mean=6+/-9.2 days; range=1 to 35 days) in the ICU. One hospital death occurred. Hospital costs per case ranged from $11,712 to $121,829, with mean costs of $30,976 and median costs of $19,771. Costs were related significantly to duration of ICU stay and length of hospitalization. Patients who accrued the highest costs were significantly older than the remainder of the sample (69.3 years vs 62.4 years). CONCLUSIONS: Hospital costs of LVRS vary significantly but are related directly to hospital stay. Identification of factors associated with prolonged stays can be used in assessing benefits and risks of LVRS against utilization of health-care dollars.

Pulmonary aspiration in hospitalized adults.

Until recent years, pulmonary aspiration attracted remarkably little clinical investigation. Although aspiration was considered a common occurrence in hospitalized individuals, with serious and even fatal consequences, clinicians had limited scientific data to guide practice. Consequently, approaches to this problem were based largely on unsystematic observations, intuition, and tradition. Recent investigations on the subjects of aspiration have increased our understanding of patients at risk for aspiration, the value of diagnostic methods, and the efficacy of interventions to prevent or limit aspirations. Results of these studies call to question many time-honored adages and practices. Considerable uncertainty remains and more investigation is necessary before management decisions can be characterized clearly and clinical strategies defined. This review focuses on pulmonary aspiration and enteral feeding in the critically ill adult. Factors implicated in aspiration in this population are highlighted and evidence to support the application of interventions prescribed commonly is presented.

Pulmonary aspiration in mechanically ventilated patients with tracheostomies.

The purpose of this descriptive study was to evaluate feeding aspirations in adult patients receiving long-term mechanical ventilatory support, including the incidence of aspirations, the frequency of silent (clinically inapparent) aspirations, and differences between aspirators and nonaspirators. Aspiration data were determined by review of videofluoroscopic (VF) tapes of modified barium swallow procedures performed on 83 medically stable patients admitted to a chronic ventilator unit. Demographic and clinical variables were obtained from review of subjects' medical records. Forty-two subjects (50 percent) aspirated during VF testing and 37 of 48 (77 percent) aspirations were silent. Subjects who aspirated were significantly older than those who did not aspirate (p = 0.007). Swallowing disorders were common, particularly disturbances of the pharyngeal phase. We conclude that feeding aspiration is seen frequently in patients with tracheostomies receiving prolonged positive pressure mechanical ventilation. Advanced age increases the risk of aspiration in this population. Episodes of aspiration are not consistently accompanied by clinical symptoms of distress to alert the bedside observer to their occurrence.

The technique of pleurodesis.

Pleurodesis may be indicated for pleural effusions (with careful patient evaluation) or recurrent pneumothoraces. It is contraindicated if tube thoracostomy fails to reexpand the lung and, possibly, if patients are candidates for lung transplantation or have congestive heart failure. We perform pleurodesis through an indwelling chest tube (alternative methods are thoracoscopy and thoracotomy). Common sclerosants include talc, doxycycline, minocycline, and bleomycin. Intrapleural administration of lidocaine may control pain, but injections of morphine or meperidine almost always are needed.

Tuberculosis update: new challenges of an old disease.

Tuberculosis has re-emerged as a major threat to personal and public health in the United States. Hospitals are high-risk environments for tuberculosis transmission, and nursing is a high-risk occupation for tuberculosis infection. It is essential for nurses to thoroughly understand and strictly adhere to infection control practices to prevent tuberculosis transmission in health care settings.

A preliminary investigation of opinions and behaviors regarding advance directives for medical care.

BACKGROUND: Advance directives are a means of promoting patient autonomy in end-of-life decisions but are used infrequently. A recent federal law requires healthcare organizations to provide information to patients about advance directives. This study explored attitudes and behaviors related to the use of advance directives in three areas: familiarity with advance directives, reasons for completing or not completing advance directives and preferences for receiving information about advance directives. METHODS: A questionnaire was administered by personal interview to a nonrandomized convenience sample of 46 inpatients and 50 outpatients at a large, tertiary care, urban academic medical center in the summer of 1991. RESULTS: Most respondents (77%) had heard of either the living will or durable power of attorney for healthcare, but only 52% correctly understood the purpose of these documents. Twenty-nine percent of the sample had executed an advance directive. Those who had advance directives were older and considered themselves less healthy than did those without advance directives. Unfamiliarity with advance directives and procrastination were cited most often as reasons for not having an advance directive. Most subjects (65%) had spoken with someone, usually a family member or close friend, about preferences for treatment during a critical illness. Although they had rarely discussed advance directives, 83% anticipated that they would be comfortable doing so with a physician or a nurse. CONCLUSIONS: Advance directives are used infrequently to document treatment preferences. The success of programs to promote greater use of advance directives depends on a clearer understanding of the factors that influence both decision and action to execute an advance directive. Patients claim to be comfortable in discussing the topic and prefer that such discussions occur in the outpatient setting.

Patients' preferences for intensive care.

OBJECTIVES: To determine patients' preferences for intensive care and to evaluate the influence of a recent ICU experience on preferences for future ICU treatment. DESIGN: Survey of nonrandomized patient sample using structured interviews. SETTING: Large, urban, tertiary academic medical center. PATIENTS: Eighty-four adult inpatients discharged from the medical ICU between June and August 1990. MEASUREMENTS: Agreement with life-supportive care under each of four potential outcome scenarios was assessed on a 5-point scale. An overall preference score was created by summing scores for the four items. Patients were also asked about their recent experiences in the ICU. RESULTS: Patients identified sources of stress associated with their ICU stay, yet most (76%) rated their ICU experience positively. Preferences for future intensive care varied with perceived outcome, and were strongest for health restoration and weakest for persistent vegetative states. No significant relationships were found between ICU preferences and any demographic or clinical variable except race. CONCLUSIONS: Patients tolerate intensive care well and desire it to restore health. Most patients modify their desire for intensive care if less favorable outcomes are likely. Patients' preferences for intensive care cannot be predicted from demographic features or previous ICU experiences.

The noninvasive respiratory care unit. Patterns of use and financial implications.

Clinical, socioeconomic, and ethical dilemmas have prompted reevaluation of traditional methods of providing intensive care. Six years ago, we established a noninvasive respiratory care unit (NRCU) for selected patients in need of intensive respiratory monitoring and therapy, particularly those requiring prolonged mechanical ventilation. One impetus for the formation of the NRCU was the expectation that it might prove to be a less costly alternative to the intensive care unit (ICU) for selected patients. We reviewed data from all patients admitted to the NRCU from July 1, 1987 through June 30, 1988 to identify characteristics of the patient population and to evaluate potential cost savings. During one year of operation, 136 patients were admitted to the unit, 107 of whom were mechanically ventilated. Overall, hospital costs for these patients exceeded payments by $1,519,477. Losses were greatest for mechanically ventilated patients and those for whom Medicare or Medicaid were the primary payors. Daily costs of care for mechanically ventilated patients were $1,976 lower in the NRCU than in the medical intensive care unit (MICU). We conclude that the NRCU represents a cost-effective approach to the care of substantial numbers of patients requiring specialized respiratory care.

Prolonged ventilator dependence: economic and ethical considerations.

Patients who receive ventilator treatment tend to be older and sicker than ever before, factors that contribute to the complexity of ventilator weaning. The provision of prolonged ventilator support entails a commitment of expensive hospital resources, yet survival is often poor. Consideration must be given to limiting ventilator treatment in instances when benefit is highly unlikely or when the burdens of treatment outweigh benefits. Decisions to withhold or withdraw mechanical ventilation must be made with full knowledge and understanding of relevant ethical principles. If ventilator support is to be terminated, this should be accomplished according to institutional protocols that take into account these ethical considerations, as well as the medical and legal facts that apply.

Advances in patient care management: the NRCU.

The noninvasive respiratory care unit has become an important advance in patient management. The NRCU allows for better use of special-care beds and represents a more cost-effective approach to the care of a number of ventilator-dependent patients or other respiratory patients. This article describes the NRCU, discusses clinical experiences and focuses on practical issues related to patient management in the NRCU.

Long-term outcomes for elderly survivors of prolonged ventilator assistance.

Care of ventilator-dependent patients requires considerable resources, yet the long-term outcomes of this type of care have rarely been described. We retrospectively investigated the posthospital course of elderly patients who survived an episode of prolonged ventilator dependency to describe survival rates, subsequent use of health care resources, and functional abilities. Our data suggest that the use of prolonged mechanical ventilation in the elderly produces few survivors at considerable expense. Poor overall outcomes occurred despite considerable consumption of medical and nursing resources by the survivors.

Staff governance. The experience of one nursing unit.

Professionalization is a common theme in nursing. As this process progresses, the utility of more traditional methods and procedures will continue to come under scrutiny. The authors describe the evolution of a system of staff governance on one nursing unit in a large urban medical center. Factors contributing to the decision to abolish line positions on the unit are discussed, as are the dilemmas the staff faced in undertaking management of the unit.

Associated practice: a case for professional collaboration.

The establishment of a successful nurse-physician associated practice requires planning, patience, and a willingness to take calculated risks. The nurse executive can lend credibility and support to the nurse in associated practice by understanding the concept, providing a climate for acceptance of such practices, and by clarifying the role of the nurse associate in relation to other professionals in the organization. In this article the authors describe models for associated practice, as well as the measures necessary to ensure peer and patient acceptance and effective health care delivery.

Effect of the Passy-Muir tracheostomy speaking valve on pulmonary aspiration in adults.

PURPOSE: We determined instances of aspiration in adults with tracheostomies and investigated the effect of the Passy-Muir tracheostomy speaking valve on occurrences of aspiration. METHODS: Adults with tracheostomies scheduled for videofluoroscopic swallowing examinations who met inclusion criteria were enrolled. According to study protocol, 6 presentations of thin liquids were recorded, 3 with and 3 without the Passy-Muir tracheostomy speaking valve. If a cuffed tube was present, the cuff was deflated fully for all presentations. RESULTS: Seven of 15 subjects aspirated material on 1 or more presentations of thin liquid. Five subjects aspirated material only with the Passy-Muir tracheostomy speaking valve off, whereas 2 subjects aspirated material with and without the valve. No subject aspirated material while the valve was on exclusively. Aspiration was significantly less frequent with the Passy-Muir tracheostomy speaking valve on than with it off. CONCLUSIONS: Clinically unapparent aspiration occurs commonly in patients with tracheostomies. An expiratory occlusive valve can reduce, though not eliminate, occurrences of aspiration. CLINICAL IMPLICATION: The benefit of the Passy-Muir tracheostomy speaking valve should be evaluated in selected patients who aspirate liquid.
