Impact of Pulmonary Rehabilitation Stewardship Program on COPD Patients, Quality Improvement Project.

Background: Pulmonary rehabilitation (PR) has multiple benefits in COPD patients. There are multiple barriers to utilize PR including lack of knowledge about the benefits of PR by providers. Objective: We are conducting a Quality Improvement project to improve the referral rate of patients hospitalized for acute exacerbation of COPD to PR. Methods: All patients admitted with a primary diagnosis of acute exacerbation of COPD requiring systemic steroids to Rochester General Hospital in the period between 7/1/2019 and 7/31/2019 were reviewed retrospectively. Between 7/15/2020 and 11/15/2020, we started a PR stewardship program, where we daily review patients hospitalized with acute COPD exacerbation, and then a note will be placed in the chart for the primary team to consider referring patients to PR upon discharge, patients' charts were reviewed after discharge. The rate of referral before and after the intervention was compared. Results: During the pre-intervention period, 16 patients (mean age 67.7) with confirmed COPD by spirometry were hospitalized for COPD exacerbation, among them only 2 were referred to PR upon discharge (12.5%). During the post intervention period, 16 patients (mean age 65.0) were admitted with acute COPD exacerbation, among them 10 were referred to PR upon discharge (62.5%) [50% difference (16.5%-71%, 95% CI), P value = 0.004]. Conclusion: In our QI improvement project, we conclude that having a PR stewardship program to review patients hospitalized with COPD exacerbation significantly improves the referral rate to PR, and might help to improve utilization of those programs by patients who need them.

Nutritional and Biochemical Parameters Among Multiple Sclerosis Patients: A Case-Control Study.

Background The pathogenesis and prognosis of multiple sclerosis (MS) is an area of active medical research. Dietary and biochemical parameters such as serum 25-dihydroxycholecalciferol, magnesium, and potassium play a role in disease progression. This study aimed to compare the nutritional status and biochemical profile of patients with and without MS. Methodology This case-control study included a total of 112 participants (56 in the control group and 56 in the MS group). The participants' socioeconomic and demographic profiles, nutritional status, and biochemical details were all gathered using history, patient files, and records. The effect of these parameters on the presence of MS was evaluated using a decision tree model. Student's t-test and Mann-Whitney U test were performed to compare these parameters. Results A decision tree model was developed with an accuracy rate of 86.52%. The vitamin and mineral intake of the groups showed significant statistical differences (p = 0.001). The differences were important in terms of biochemical parameters, especially serum levels of 25-dihydroxycholecalciferol and potassium. Conclusions The key parameters that varied between MS patients and the control group, according to the constructed decision tree, were serum levels of 25-dihydroxycholecalciferol, magnesium, calcium, potassium, and carbohydrate intake. Nutritional measures against MS can be taken based on the decision tree.

Efficacy of a Dehydrated Hydrogel Plug to Reduce Complications Associated With Computed Tomography-guided Percutaneous Transthoracic Needle Biopsy.

PURPOSE: The aim of the study was to determine whether a hydrogel plug, when placed in the needle tract after a computed tomography-guided percutaneous transthoracic needle lung biopsy, reduces the rate of complications. MATERIALS AND METHODS: This retrospective analysis included biopsies of lung lesions from 200 consecutive patients. The first 100 consecutive biopsies made up the control group, in which no plug intervention was used. The next 100 consecutive biopsies made up the treatment group, in which a hydrogel plug was deployed through a 19-G coaxial needle system after 20-G core samples were obtained. RESULTS: The overall mean age was 64.92 years. No statistically significant differences in patient characteristics and procedure parameters were found between the control and treatment groups except for age (mean age, 62.92 vs. 66.92 y, P=0.022) and procedure duration (mean minutes, 7.81 vs. 6.47 min, P=0.021). The rate of pneumothorax in the control versus treatment group was 31% vs. 29% (P=0.498) and the rate of hemoptysis was 6% vs. 3% (P=0.354). The rate of chest tube insertion after pneumothorax was significantly higher in the control group than in the treatment group (10% vs. 2%, P=0.032) and the average length of hospital stay was longer in the control group (0.44 vs. 0.07 d, P=0.041). The difference was still statistically significant for the chest tube insertion rate (P=0.030) and close to statistically significant for the length of hospital stay (P=0.063), after adjusting for the confounding effect of age and procedure duration. CONCLUSION: These data show that the deployment of a hydrogel plug after a computed tomography-guided lung biopsy significantly reduced the rate of chest tube insertion along with a reduced length of hospital stay.
