Improving pulmonary rehabilitation services.

The Clinical Audit of Pulmonary Rehabilitation Services in England and Wales was the first national audit of pulmonary rehabilitation services in England and Wales. Forming part of the National Chronic Obstructive Pulmonary Disease Audit Programme, it was commissioned by Healthcare Quality Improvement Programme and conducted by the Royal College of Physicians and British Thoracic Society. The audit was undertaken to geographically map pulmonary rehabilitation services and identify how they can improve. This article summarises the key findings of the audit, and its recommendations.

The impact of different nursing skill mix models on patient outcomes in a respiratory care center.

BACKGROUND: Many hospitals have reformed hospital policies and changed nursing models to cope with shortages in nursing staff and control medical costs. However, the nursing skill mix model that most successfully achieves both cost effectiveness and quality care has yet to be determined. AIM: The aim of this study was to explore the impact of different nurse staffing models on patient outcomes in a respiratory care center (RCC). METHODS: Retrospective data from 2006 to 2008 were obtained from records monitoring nursing care quality, as well as patient records and nursing personnel costs in an RCC as a medical center, in southern Taiwan. A total of 487 patients were categorized into two groups according to the RCC's mix of nursing staff. The "RN/Aide" group comprised 247 patients who received RN and aide care, with a 0.7-0.8 proportion of RNs, from July 2006 to June 2007. The other 240 patients ("All-RN") received 100% RN care from January 2008 to December 2008. RESULTS: The results of this study indicated no significant differences in occurrence of pressure ulcer or respiratory tract infections, days of hospitalization, mortality, or nursing costs. However, significant differences were observed in ventilator weaning and occurrence of urinary tract and bloodstream infections. CONCLUSIONS: A higher proportion of RNs was associated not only with a lower rate of urinary tract infection but also with more patients being weaned successfully from ventilators. The findings of this study have implications for how managers and administrators manage nurse staffing in respiratory care.

Bayesian methods of analysis for cluster randomized trials with count outcome data.

Bayesian approaches to inference in cluster randomized trials have been investigated for normally distributed and binary outcome measures. However, relatively little attention has been paid to outcome measures which are counts of events. We discuss an extension of previously published Bayesian hierarchical models to count data, which usually can be assumed to be distributed according to a Poisson distribution. We develop two models, one based on the traditional rate ratio, and one based on the rate difference which may often be more intuitively interpreted for clinical trials, and is needed for economic evaluation of interventions. We examine the relationship between the intracluster correlation coefficient (ICC) and the between-cluster variance for each of these two models. In practice, this allows one to use the previously published evidence on ICCs to derive an informative prior distribution which can then be used to increase the precision of the posterior distribution of the ICC. We demonstrate our models using a previously published trial assessing the effectiveness of an educational intervention and a prior distribution previously derived. We assess the robustness of the posterior distribution for effectiveness to departures from a normal distribution of the random effects.

Psychological effects of chronic lung disease.

Carol Kelly and Dave Lynes outline the potential psychological consequences of living with a chronic respiratory disease and how nurses can assess problems and implement strategies to help patients to adjust and cope.

Videoconferencing and telehealth technologies can provide a reliable approach to remote assessment and teaching without compromising quality.

Cardiovascular disease remains a significant chronic healthcare problem in this country, with considerable associated economic and quality-of-life challenges. Along with these challenges, there is high demand for healthcare provider time, particularly in the areas of management of complex healthcare needs and patient education. At the same time, a critical nursing shortage exists. Telehealth technologies provide opportunities to meet the rapidly growing needs of consumers and healthcare practitioners. Many in need of services have limited access to high-end technologies. An argument has been made that the lowest level of technology needed to carry out a task should be used, if it is capable of providing the necessary services. Videoconferencing capabilities allow healthcare practitioners to engage in virtual face-to-face encounters with patients or other healthcare providers. A variety of levels of sophistication in these videoconferencing systems are available. In an effort to evaluate the effectiveness and consumer satisfaction with videoconferencing, 3 pilot studies were conducted to compare face-to-face, low-bandwidth, and high-bandwidth approaches to performing common assessments and patient education activities. In one study, a variety of experienced healthcare practitioners performed functional assessments of stroke subjects using a collection of validated scales by varying approaches (face-to-face, low-bandwidth, and high-bandwidth videoconferencing) in a randomized order. In a second study, undergraduate nursing students performed similar performance measures and taught an unfamiliar individual how to program and use an intravenous pump device, take a tympanic temperature, or to draw up insulin in a syringe. In the third study, advanced practice nursing students assessed vital signs and performed cardiopulmonary assessments on community-dwelling subjects using low-bandwidth and face-to-face approaches. Healthcare practitioners and students generally preferred high-bandwidth approaches over low-bandwidth alternatives when videoconferencing was performed; however, most participants and practitioners were satisfied with the encounters, regardless of the level of technology used.

Development and evaluation of a PBL-based continuing education for clinical nurses: a pilot study.

PURPOSE: The purposes of this study were to develop a PBL program for continuing nurse education and to evaluate the program after its implementation. METHODS: The PBL program was developed in the core cardio-pulmonary nursing concepts through a collaborative approach with a nursing school and a hospital. The PBL packages with simulation on ACLS were implemented to 40 clinical nurses. The entire PBL program consisted of six 3-hour weekly classes and was evaluated by the participants' subjective responses. RESULTS: Two PBL packages in cardio-pulmonary system including clinical cases and tutorial guidelines were developed. The 57.5% of the participants responded positively about the use of PBL as continuing nurse education in terms of self-motivated and cooperative learning, whereas 20.0% of the participants answered that the PBL method was not suitable for clinical nurses. Some modifications were suggested in grouping participants and program contents for PBL. CONCLUSION: The PBL method could be utilized to promote nurses' clinical competencies as well as self-learning abilities. Further research is needed in the implementation strategies of PBL-based continuing education in order to improve its effectiveness.

Palliative care for people with end-stage non-malignant lung disease.

Progressive non-malignant lung disease (PNMLD) is a common cause of morbidity and mortality in the UK. In 1999, chronic lung disease--including chronic obstructive pulmonary disease (COPD), tuberculosis, pulmonary circulatory disease, pneumonoconiosis, sarcoidosis and cystic fibrosis--killed almost 39,000 (British Thoracic Society, 2000), while it is estimated that 600,000 people in the UK have COPD, the most common non-malignant lung disease (BTS, 2001).

Procedure for the assessment of lung function with spirometry.

Spirometry records breath movements, inhalation and exhalation, and is integral to the management of lung disease, alongside good history taking and careful documentation. Tests can indicate a patient's optimal response to treatment or triggers, and the rate of decline in lung function. It is useful to detect the presence of lung disease, those susceptible to developing lung disease and to classify patients into severity classifications to optimise management.

Informal caregiving for chronic lung disease among older Americans.

STUDY OBJECTIVE: To obtain nationally representative estimates of the additional time, and related cost, of unpaid family caregiving (informal caregiving) associated with chronic lung disease among older Americans. DESIGN: Multivariable regression models using data from the 1993 Asset and Health Dynamics Study, a nationally representative survey of people > or = 70 years old (n = 7,443). PARTICIPANTS: National population-based sample of the community-dwelling elderly. MEASUREMENTS: Weekly hours of informal caregiving, and imputed cost of caregiver time, for community-dwelling elderly who reported the following: (1) no lung disease, (2) lung disease without associated activity limitations, or (3) lung disease with associated activity limitations. RESULTS: After adjusting for sociodemographic variables, potential caregiver network, and comorbid conditions, individuals with chronic lung disease and associated activity limitations (n = 403) received an additional 5.1 h/wk of informal care when compared to those with no lung disease (n = 6,593; p < 0.001). The associated additional yearly cost of informal care per case was $2,200 USD. This represents a national annual cost of informal caregiving for chronic lung disease of > $2 billion USD. CONCLUSIONS: The quantity and associated economic cost of informal caregiving for elderly individuals with chronic lung disease are substantial. These costs to families and society must be accounted for if the full societal costs of chronic lung disease are to be calculated. Pulmonary physicians caring for elderly individuals with chronic lung disease should be mindful of the importance of informal care for the well-being of their patients, as well as the potential for significant burden on those (often elderly) individuals providing the care.

Synergizing acute care and palliative care to optimise nursing care in end-stage cardiorespiratory disease.

Advances in the practice of medicine and nursing science have increased survival for patients with chronic cardiorespiratory disease. Parallel to this positive outcome is a societal expectation of longevity and cure of disease. Chronic disease and the inevitability of death creates a dilemma, more than ever before, for the health care professional, who is committed to the delivery of quality care to patients and their families. The appropriate time for broaching the issue of dying and determining when palliative care is required is problematic. Dilemmas occur with a perceived dissonance between acute and palliative care and difficulties in determining prognosis. Palliative care must be integrated within the health care continuum, rather than being a discrete entity at the end of life, in order to achieve optimal patient outcomes. Anecdotally, acute and critical care nurses experience frustration from the tensions that arise between acute and palliative care philosophies. Many clinicians are concerned that patients are denied a good death and yet the moment when care should be oriented toward palliation rather than aggressive management is usually unclear. Clearly this has implications for the type and quality of care that patients receive. This paper provides a review of the extant literature and identifies issues in the end of life care for patients with chronic cardiorespiratory diseases within acute and critical care environments. Issues for refinement of acute and critical care nursing practice and research priorities are identified to create a synergy between these philosophical perspectives.

Assessment of strategies in families tested by Finnish families.

The aim of this paper was to describe testing a Finnish version of the assessment of strategies in families (ASF) instrument and its construct validity and reliability in Finnish families. The ASF instrument is based on Friedemann's framework of systemic organization and the version used in this study consists of 25 items, each containing three statements. The instrument was developed to estimate family functioning in reaching the four targets of the framework of systemic organization. It provides sub-scores for the targets, family stability (system maintenance and coherence), family growth (system change and individuation), control (system maintenance and system change) and spirituality (individuation and coherence). Data were collected from patients attending the outpatient clinics of pulmonary and rheumatic diseases (N=196). Questionnaires were given to patients capable of understanding the questions and they returned questionnaires by mail directly to researchers. Construct validity was tested with exploratory factor analysis. Factor analysis was done with 22 items. The four factor solution was best suited. Two items were eliminated because of low factor loadings and crossloading. The total of 20 items were left in the instrument. Crohnbach's alpha was used to measure internal consistency. It was computed for each target separately and the total tool. There were discrepancies in the assignment of process dimensions which were expected because of cultural perceptions. The total instrument had a reliability of 0.85. The result of the analyses was a pretested tool with subscales for stability, growth, control and spirituality that have acceptable reliability and concept validity. Less satisfactory was the small number of items representing individuation. Another weakness is the lack of statistical distinction between system maintenance and coherence. The instrument is also usable in these subscales, but it needs further development and retesting. Items need to be added to express individuation, possibly some others. The new items will be formulated freely, paying attention to culture. However, the tool appears good enough to be used as measurement in various research studies.

Using variance tracking to improve outcomes and reduce costs.

Clinical pathways outline patient-care delivery over time for specific patient populations, but their true utility is derived from information obtained through variance tracking-documenting when and why a patient's care varies from the clinical pathway. This article describes one health care facility's variance tracking for pulmonary, medical oncology, and nephrology patients and their associated measured outcomes. Avoidable hospital days were tracked and a performance improvement initiative, focused on the pathways most often used on the medical unit, was undertaken, resulting in decreased length of patient stay and cost savings of more than $160,000.

Respiratory assessment in critical care units.

As healthcare delivery changes in critical care, nursing continues to extend its practice base. Nursing practice is expanding to incorporate skills once seen as the remit of the medical profession. Critical care nurses are equipping themselves with evidence-based knowledge and skills that can enhance the care they provide to their patients. Assessment of patients is a major role in nursing and, by expanding assessment techniques, nurses can ensure patients receive the care most appropriate to their needs. Nurses in critical care are well placed to perform a more detailed assessment which can help to focus nursing care. This article describes the step-by-step process of undertaking a full and comprehensive respiratory assessment in critical care settings. It identifies many of the problems that patients may have and the signs and symptoms that a nurse may not whilst undertaking the assessment and preparing to prescribe care.
