Demographics and clinical outcomes of patients admitted to a respiratory intensive care unit located in a rehabilitation center.

INTRODUCTION: A recent survey of respiratory intensive care units (RICU) in Italy showed that RICUs in Italy are mainly (85%) located in acute care hospitals. Forty-seven percent of the patients are admitted from emergency departments, and only 18% are admitted from intensive care units (ICU), so the percentage of patients admitted for difficulty in weaning is low (8%). Patient demographics and admission patterns in RICUs located outside acute care hospitals have not been previously described. METHODS: We analyzed admission patterns, demographics, treatment, and outcomes of patients during the first year of operation of a 7-bed RICU located in a rehabilitation center that does not have an emergency department. RESULTS: In the 1-year study period, 96 RICU patients were admitted for acute or chronic respiratory failure. The patients' mean Simplified Acute Physiology Score II was 28.9 +/- 3.6. Sixty-five percent of the patients were transferred from the ICU, 17% from medical wards of other hospitals, 7% and 5%, respectively, from the medical and surgical wards of our hospital, and 6% came directly from home for a periodic check. Difficulty in weaning from mechanical ventilation was the main reason for admission (42%), followed by simple monitoring (37%) and need for acute ventilatory invasive or noninvasive support (21%). Thirty-one patients had COPD, 23 had acute hypoxemic respiratory failure, 30 had post-surgical complications, and 12 had neuromuscular disease. Twenty-seven of 40 patients admitted for difficulty in weaning were liberated from ventilation. Intrahospital mortality was 13%. Fifty percent of patients were discharged directly to home; those patients' mean Dependence Nursing Scale score (which measures the degree of patient independence) improved during hospital stay (decreased from 23 to 12 [p < 0.05]), whereas the remaining patients were transferred to long-term facilities or an acute care hospital. CONCLUSIONS: The admission pattern at our RICU in a rehabilitation center is quite different from that of an RICU in an acute care hospital. Most of our patients are admitted from ICU because of difficulty with weaning. This may be the consequence of the institutional philosophy of rehabilitation centers, which strive to achieve greater patient independence.

Costs of occupational asthma and of occupational chronic obstructive pulmonary disease.

PURPOSE OF REVIEW: The purpose of this review is to summarize the most recent findings on the costs of occupational asthma and chronic obstructive pulmonary disease, illustrating the different approaches for estimates, the results and the social and financial implications. RECENT FINDINGS: Many published data in the literature show that occupational asthma and chronic obstructive pulmonary disease represent a relevant proportion of the total prevalence of these diseases. Previous findings demonstrated that occupational asthma has adverse economic and employment consequences for the worker, and a significant cost related to the claims. Recent studies using a standard method have specifically estimated the cost of the proportion of cases of asthma and chronic obstructive pulmonary disease attributable to occupational exposure out of the total costs of these diseases, and demonstrated that it is significant. Some recent data indicate a beneficial outcome of occupational asthma and a reduction in the number of the claims from primary and secondary preventive intervention at the workplace. SUMMARY: In conclusion, occupational asthma and chronic obstructive pulmonary disease are likely to pay a substantial contribution to the total costs of the two disorders. These costs are expected to rise with the increasing prevalence of the diseases. Intervention strategies for effective control and prevention at the workplace should lessen the burden of long-term illness and impact on public health costs.

Weaning from tracheotomy in long-term mechanically ventilated patients: feasibility of a decisional flowchart and clinical outcome.

OBJECTIVE: To assess the feasibility of following a decisional flowchart to decide whether to remove tracheotomy in long-term mechanically ventilated patients. DESIGN AND SETTING: Prospective study in a respiratory intensive care unit, with beds dedicated to weaning from prolonged mechanical ventilation. PATIENTS AND PARTICIPANTS: 108 tracheotomized patients with respiratory failure of different causes (chronic obstructive pulmonary disease, postsurgical complications, recovery from hypoxemic respiratory failure, neuromuscular disorders), 36 of whom died or could not be weaned from mechanical ventilation. INTERVENTIONS: We applied a decisional flowchart based on some simple clinical and physiological parameters aimed at assessing the patient's ability to remove secretions, swallowing function, absence of psychiatric diseases, possibility of reaching spontaneous breathing, and amount of respiratory space. MEASUREMENTS AND RESULTS: Following our flowchart 56 of the remaining patients were successfully weaned from the tracheotomy cannula, with a reintubation rate at 3 months of 3%. The main reasons for not proceeding to decannulation were inability to remove secretions and severe glottic stenosis. No statistical differences were found between patients who received a surgical or percutaneous tracheotomy. CONCLUSIONS: Using a simple decisional flowchart we were able to remove tracheotomy cannula in almost 80% of the patients with spontaneous breathing autonomy without major clinical complications. Further larger prospective studies are needed to confirm this clinical approach in larger and different populations.
