The number of elderly people with small cell lung carcinoma (SCLC) is increasing and currently nearly 25% are older than 70 years. Elderly patients may not tolerate intensive therapy and, therefore, often do not receive such treatment. Additionally, age may be an independent predictor for response and survival. We compared the investigation, staging procedure, and management of patients less than 60 years, 60 to 69, and older than 70 years who were diagnosed with SCLC between 1985 and 1991. We hypothesized that elderly patients were investigated and treated less aggressively, and that their outcome was poorer than that of younger patients with SCLC.

PURPOSE To document the use/misuse of oxygen therapy as compared with antibiotics in internal medicine inpatients. To determine whether the same care was being taken in the prescription and administration of both forms of therapy. PATIENTS Ninety-six eligible patients at a university teaching hospital were entered into a study examining the use of oxygen. They were compared with 60 patients for whom antibiotics were prescribed. MATERIAL AND METHODS Three hundred thirty consecutive newly admitted patients were screened for the presence of either (1) oxygen apparatus at the bedside, (2) physician orders for oxygen, or (3) oxygen orders noted in nursing kardex. Those meeting one of these three criteria were observed on up to four occasions over 48 hours following study entry. Similarly, patients were screened for medical orders or nursing medication kardex notation for antibiotics and were also observed for proper prescription and administration of medication. Procedural errors, determined by kardex audit and direct patient observation, were compared for the individuals with specific oxygen orders and those receiving antibiotics. RESULTS Oxygen delivery apparatus was found in the room in 17 of 96 patients without it ever having been ordered by the physician or noted in the nursing kardex. In 27 of 96 patients, oxygen was noted in the nursing kardex and administered to patients without a physician order. There were no cases of antibiotic therapy without a physician order. Observations of 47 patients with specific orders for oxygen revealed the following errors: (1) physician order incorrectly transcribed to nursing kardex (16%), (2) flow meter off (34%), (3) oxygen delivery apparatus improperly worn (57%), (4) wrong fractional inspired oxygen concentration (58%). Improper transcription of antibiotic orders occurred on only one occasion (2%), and antibiotics were improperly administered in 5%. Arterial blood gas determinations preceded oxygen orders in 61%, whereas microbiologic cultures preceded antibiotic orders in 87% of the patients. CONCLUSIONS We conclude that oxygen therapy is neither prescribed nor administered with the same attention that is given to other drugs such as antibiotics. Oxygen prescription and/or delivery is associated with significantly greater error than that seen with antibiotics. Education of medical personnel should stress more prudent prescription and use of oxygen in hospitalized patients.

Introduction: The Eastern Cooperative Oncology Group (ECOG) score is a well known prognostic factor and almost always used to determine eligibility for clinical trials. The patient-rated performance status score (Pt-PS), section of the patient generated subjective global assessment scale, has identical criteria to the physician-rated ECOG scale (MD-PS). We compared the Pt-PS with MD-PS in patients with advanced non-small cell lung cancer and compared the effect of each rating on eligibility for a hypothetical clinical trial. Methods: Consecutive patients with newly diagnosed advanced non-small cell lung cancer completed a patient generated subjective global assessment self-rated questionnaire, which was then correlated (kappa statistic) with the ECOG PS recorded at the same time. Patients were treated with standard chemotherapy. Survival was determined using Kaplan-Meier statistics. Results: One hundred nine patients (M:F-54:55) were recruited. Pt-PS differed from MD-PS in 59 (54%) instances (p = 0.0001). When scores were not congruent, 41/59 (69%) patients evaluated themselves as having a worse PS than the physician’s rating. Pt-PS was 0 to 1 in 60 (55%) patients whereas MD-PS was 0 to 1 in 78 (72%) patients. The functional status irrespective of evaluator was predictive of survival (p = 0.001 for MD-PS and p = 0.001 for Pt-PS). However, the median survival in those with MD-PS ≥2 was 3.3 (CI; 1.7-4.9) months whereas individuals with Pt-PS ≥2 had a median survival of 6.2 (CI; 5.4-6.9) months. Conclusions: Pt-PS and MD-PS were not congruent in over half of the cases, with Pt-PS scores usually poorer. Almost half the patients would have excluded themselves from a hypothetical clinical trial (Pt-PS ≥2). This requires prospective evaluation.

OBJECTIVE The present pilot study tested the use of a virtual game system (VGS) for exercise training in patients with moderate to very severe chronic obstructive pulmonary disease undergoing pulmonary rehabilitation (PR). Safety, feasibility, enjoyment and adherence were assessed. METHODS VGS (Wii [2006], Nintendo, USA) games were prescreened and categorized into lower- and upper-body workouts. Patients admitted for a three- to four-week inpatient PR program exercised daily. They were provided an opportunity to individually engage in VGS sessions three times weekly, varying with length of stay. Dyspnea, oxygen saturation and heart rate were measured before, during and after game sessions. Patients were considered to be adherent if they attended at least 50% of VGS sessions. Adverse events and enjoyment were evaluated. RESULTS Thirty-two patients with a mean (± SD) age of 66±9 years and a mean forced expiratory volume in 1 s of 0.72±0.40 L participated. Among the 25 patients completing the program, adherence was 76%, with a mean attendance rate of 64±35%. Mean dyspnea score was 1.5±1.1 before and 3.2±1.2 after exercise. Mean oxygen saturation changed from 94±3% to 91±5% (P<0.001), while heart rate increased from 88±15 beats⁄min to 102±18 beats⁄min (P<0.001). One patient reported chest pain requiring nitroglycerin spray and five experienced transient desaturation below 85% with play. Patients enjoyed the program (visual analogue score 8±2.6⁄10) and most would highly recommend it to others. CONCLUSIONS Moderate exercise using a VGS was safe, feasible and enjoyed as an adjunct to inpatient PR. This modality may encourage patients to maintain physical activity after PR.

BACKGROUND Chronic obstructive pulmonary disease (COPD) is a progressive and distressing disease with a trajectory that is often difficult to predict. OBJECTIVE To determine whether initial 6 min walk distance (6MWD) or change in 6MWD following inpatient pulmonary rehabilitation (PR) predicted survival. METHODS Patients referred for PR in 2010 were studied in a retrospective chart review. Measures of 6MWD before and following PR were recorded. Initial 6MWD was categorized as ≥250 m, 150 m to 249 m and ≤149 m. Government databases provided survival status up until December 2013 and survival analyses were performed. Initial 6MWD and a minimally important difference (MID) of ≥30 m were used for survival analysis. RESULTS The cohort consisted of 237 patients (92 men, 145 women) with severe COPD. Mean (± SD) forced expiratory volume in 1 s (FEV1) was 0.75±0.36 L, with a mean FEV1/forced vital capacity (FVC) ratio of 0.57±0.16. Overall three-year survival was 58%. Mean survival for the study period as per predefined categories of 6MWD of ≥250 m, 150 m to 249 m and ≤149 m was 42.2, 37.0 and 27.8 months (P<0.001), respectively, with a three-year survival of 81%, 66% and 34% observed, respectively. Overall mean change in 6MWD was 62±57 m, and a minimal improvement of ≥30 m was observed in 72% of patients. In the lowest walking group, early mortality was significantly higher among those who did not achieve minimal improvement. Older age, male sex and shorter initial 6MWD were negative predictors of survival. CONCLUSION In patients with severe COPD, initial 6MWD was predictive of survival. Overall survival at three years was only 58% and was especially poor (34%) in patients with low (<150 m) initial walk distance.

Patient education is integral to the care of patients with chronic obstructive pulmonary disease (COPD), and a cornerstone of self-management in chronic illness. We aimed to assess information needs and knowledge of patients with COPD. The Lung Information Needs Questionnaire (LINQ) and The Mount Sinai Hospital Questionnaire (MSHQ) were used. The LINQ identifies what COPD information the patient has, or is lacking. Higher scores in the LINQ define a greater information need. The MSHQ assesses a patients’ COPD knowledge. Higher scores in the MSHQ questionnaire indicate greater knowledge. Subjects, in (n = 38) and outpatients (n = 43) were aged (mean ± SD) 69 ± 9 years, 53% were women, and 36% had not completed high school. COPD was diagnosed 9 ± 7 years previously. Forty percent had recalled receiving specific COPD education. Mean forced expiratory volume in 1 second (FEV1) was 1.1 ± 0.6 Liters. Patients on average had a 29 ± 14% need for information as assessed by the LINQ. Patients indicated a 52 ± 34% need for information on diet and 43 ± 25% for self-management. The mean total score for the MSHQ was 71 ± 13%. The score on treatment was 76 ± 20% and 60 ± 14% on pathophysiology. There was a positive relationship between having prior COPD education, finishing high school and total MSHQ score (p< 0.05) and a positive correlation of prior COPD education and reduced LINQ total score (p < 0.01). Patients with COPD have received information and demonstrate some knowledge about their disease. However, there remains a need for more education on diet and self-management.

Background: Platinum-based chemotherapy is standard treatment for patients with advanced lung cancer. The common side effect of this therapy is myelosuppression, for which different stimulating factors are used. In this article, the effect of granulocyte colony–stimulating factor (G-CSF) administration on the survival of patients with unresectable non–small-cell lung cancer (NSCLC) was evaluated. Methods: The charts of 127 patients, treated with carboplatin-based chemotherapy, were reviewed for histology, stage, performance status, weight loss, treatment regimen, toxicity, and survival. Eighty patients were stage IIIA/IIIB NSCLC; 47 were stage IIIB (pleural effusion) or stage IV. Eighty-one patients (63%) experienced severe (grades 3 and 4) neutropenia. Forty-two patients received G-CSF, 37 patients for severe neutropenia (14 with febrile neutropenia) and five patients for active infection during chemotherapy. Results: Preliminary analyses, both unadjusted (median survival, 20 months versus 13.8 months; log-rank test, p = 0.02) and adjusted for covariates of interest (Cox regression, hazard ratio = 0.62, p = 0.03) showed a significant effect of the use of G-CSF on survival, even though the groups were balanced with respect to stage, performance status, weight loss, and dose intensity of chemotherapy. Patients with grades 3 and 4 neutropenia (whether they received G-CSF or not) had a better survival outcome compared to those who did not have neutropenia (median survival, 17.6 months versus 11.9 months, log-rank test, p = 0.04). A landmark analysis showed a marginally significant effect of G-CSF on survival (median survival, 18.6 months versus 15.1 months, log-rank test, p = 0.08), even after adjustment for covariates. The Cox regression with the use of G-CSF defined as a binary time-varying covariate also showed similar results (Cox regression, hazard ratio = 0.67, 95% CI: 0.42–1.04, p = 0.07). Conclusion: In this study, the time bias due to the delayed administration of G-CSF contributed to the longer survival of patients receiving G-CSF. Prospective studies are required to determine whether G-CSF has any effect on survival in patients with advanced NSCLC.

BACKGROUND Targeted spirometry screening for chronic obstructive pulmonary disease (COPD) has been studied in primary care and community settings. Limitations regarding availability and quality of testing remain. A targeted spirometry screening program was implemented within a presurgical screening (PSS) clinic to detect undiagnosed airways disease and identify patients with COPD/asthma in need of treatment optimization. OBJECTIVE The present quality assurance study evaluated airflow obstruction detection rates and examined characteristics of patients identified through the targeted screening program. METHODS The targeted spirometry screening program was implemented within the PSS clinic of a tertiary care university hospital. Current or ex-smokers with respiratory symptoms and patients with a history of COPD or asthma underwent prebronchodilator spirometry. History of airways disease and smoking status were obtained during the PSS assessment and confirmed through chart reviews. RESULTS After exclusions, the study sample included 449 current or ex-smokers. Abnormal spirometry results were found in 184 (41%) patients: 73 (16%) had mild, 93 (21%) had moderate and 18 (4%) had severe or very severe airflow obstruction. One hundred eighteen (26%) new cases of airflow obstruction suggestive of COPD were detected. One-half of these new cases had moderate or severe airflow obstruction. Only 34% of patients with abnormal spirometry results had reported a previous diagnosis of COPD. More than one-half of patients with abnormal spirometry results were current smokers. CONCLUSIONS Undiagnosed airflow obstruction was detected in a significant number of smokers and ex-smokers through a targeted screening program within a PSS clinic. These patients can be referred for early intervention and secondary preventive strategies.
