Trends in Lung Surgery: Procedure-Related Complications

Studies have suggested that there are better outcomes if lung surgery is performed in high-volume hospitals. While a trend to increasing mortality over time in hospitals with < 99 beds was seen compared to a decrease in mortality in hospitals with a size of 100 to 199 beds, these data are to be interpreted with caution as they may potentially be unstable due to the … Continue reading

Trends in Lung Surgery: Length of Care and Hospital Discharge Status

The average length of care after lung resection for all indications decreased dramatically over 15 years. This decrease may be explained by factors such as the identification of reasons for prolonged stays and ways to address them, the advent of new surgical techniques such as VATS, and the maturation of patient care pathways. We found that the number of patients being discharged from the hospital … Continue reading

Trends in Lung Surgery: Age, Insurance Status, Gender, and Race

A number of factors, including improved medical care, have led to an ever-increasing age among the general patient population. However, advanced age is not typically considered a contraindication for lung surgery, and the number of patients over the age of 65 years presenting for surgery has been steadily increasing. Our data are in concordance with this described phenomenon. Although the overall change in the average … Continue reading

Trends in Lung Surgery: Discussion

This study analyzed nationally representative data of lung resections in the United States between 1988 and 2002. We identified a number of changes over time related to patient age, gender, race, disposition status, expected source of payment, hospital size, length of hospital stay, and mortality. Temporally, patients undergoing lung surgery were older, more likely to be female, had a shorter length of stay, were less … Continue reading

Trends in Lung Surgery: In-Hospital Mortality

Table 4 presents the characteristics of patients who underwent lung resections who died during the entire study period (1988 to 2002) and by time period (1988 to 1992, 1993 to 1997, and 1998 to 2002). From 1988 to 2002, 4.8% of patients undergoing lung resections died during their hospitalization. In comparison to all patients who had undergone lung resections, the patients who died were an … Continue reading

Trends in Lung Surgery: Patients

Over time, fewer patients were discharged to their home residence and an increasing proportion was discharged to short-term and long-term care facilities. An increase in the proportion of Medicare and Medicaid patients was also found, most recently representing > 55% of all patients. The proportion of procedures performed in the smallest and the largest hospitals (< 99 and > 500 beds, respectively) increased compared to … Continue reading

Trends in Lung Surgery: General

The mortality of patients undergoing lung resections was also examined. For this analysis, the characteristics of the patients who died were compared to the characteristics of the entire sample of those undergoing lung resections during the study period. Changes in mortality between time periods were also assessed, but these analyses must be interpreted with caution, as the weighted number of patients having a fatal outcome … Continue reading

Trends in Lung Surgery: Patient Selection and Analysis

To ensure accurate, nationally representative sampling, the NHDS uses a complex three-stage probability design. Information collected in the survey included diagnosis and procedure codes (ie, International Classification of Diseases, ninth revision, clinical modification [ICD-9-CM]), age, sex, race, principal expected source of payment (ie, insurance status), length of care, hospital size, and patient discharge status. Weighted data, with weights derived from census data by the NHDS, … Continue reading

Trends in Lung Surgery

Over the last century, the surgical resection of lung tissue has remained an invaluable intervention in the treatment of pulmonary malignancies, traumatic lung injury, and a variety of infectious pulmonary diseases. A number of factors, such as technical innovations and a dynamic patient population, have subjected the field of thoracic surgery to constant evolution. Knowledge of these temporal changes, especially as they are related to … Continue reading

Continuous Positive Airway Pressure Modulates Effect of Inhaled Nitric Oxide on the Ventilation-Perfusion Distributions in Canine Lung Injury: Content

This effect has been attributed to selective vasodilation in ventilated lung regions It has been suggested that inhaled NO by its lipophilic properties diffuses directly into the smooth muscle of the pulmonary resistance vessels in the proximity of alveoli, and activates soluble guanylate cyclase. This increases intracellular guanosine 3,5-cyclic monophosphate (cGMP) and causes smooth muscle relaxation. Simultaneously, inactivation of NO in the blood seems to … Continue reading
