Effectiveness of a Program to Raise Awareness About Pneumococcal Vaccination Among Physicians and Patients with Chronic Respiratory Diseases: A Multicenter Cohort Study.

OBJECTIVE: There is a need to increase patient and clinician awareness on the effectiveness of pneumococcal vaccination in at-risk groups. The aim of the study was to evaluate the effect of reminders for physicians and patients using the vaccination tracking system created in the hospital information management system (HIMS) on the vaccination rate, and the effect of pneumococcal vaccination on pneumonia-related hospitalization and mortality over a 12-month period. MATERIAL AND METHODS: This prospective observational cohort study was undertaken during a 2-year period in 3 tertiary care centers. Patients were followed up for 12 months following vaccination, and hospital admissions and mortality were recorded via HIMS. During the campaign, HIMS transmitted pneumococcal immunization reminder messages in accordance with guideline recommendations to physicians' computers and patients' mobile phones. Educational posters on pneumococcal vaccination were posted in outpatient clinics. Regular seminars on the evidence for pneumococcal vaccination were organized. All patients who were hospitalized during the follow-up period for chronic obstructive pulmonary disease (COPD), asthma, lung cancer, or pneumonia were analyzed in relation to their vaccination history regarding clinical outcomes. RESULTS: A total of 29530 patients were included in the study. During the study period, the annual vaccination rate increased by 74.4% and reached 4.8% in 3 hospitals (P = .001). The rates were 3.9% in patients older than 65 years without comorbidities and 5.2% in those with COPD and asthma (P = .002). In pneumococcal vaccine recipients, pneumonia-related hospital mortality was lower (relative risk (RR) = 0.19, CI 0.09-0.35, P < .001). CONCLUSION: It is possible to raise the rate of pneumococcal vaccination through awareness campaigns. Individuals with COPD and asthma are more willing to receive pneumococcal vaccination. Among patients hospitalized for pneumonia, prior pneumococcal vaccination is associated with lower mortalit.

Analysis of post-COVID symptoms and predisposing factors for chronic post-COVID syndrome.

Introduction: While there is sufficient information about acute COVID-19, which can cause a multisystemic and fatal disease, post-COVID syndrome and risk factors for this condition remain poorly known. We aimed to identify postCOVID symptoms and risk factors for chronic post-COVID syndrome through this study. Materials and Methods: This prospective cross-sectional study was conducted on 254 out of 384 COVID-19 patients admitted to our COVID-19 polyclinic between February and April 2021. The patients were questioned with a list of 37 symptoms at the fifth and twelfth weeks after disease onset via phone review, and their acute post-COVID (APC) and chronic post-COVID (CPC) symptoms were recorded. Data on risk factors were collected from the hospital's medical records system. Associations between symptom count in the CPC phase and age, sex, hospitalization, RT-PCR result, specific radiological findings, comorbidities, and long-term medications were evaluated. Result: Two hundred twenty-one patients had APC symptoms, and 138 patients had CPC symptoms. While the most common symptom was fatigue at week five, it was hair loss at week 12. Symptoms were observed significantly less in the CPC phase than in the APC phase (Z= -12.301, p= 0.00). Female sex and the presence of specific radiological findings were significantly associated with the occurrence of CPC symptoms (p= 0.03, p= 0.00, respectively). Long-term use of angiotensin-2 receptor blockers (ARBs) was correlated with a low symptom count in the CPC phase (p= 0.00). Conclusions: Female sex and the presence of specific radiological findings were risk factors for developing CPC. Long-term use of ARBs was associated with a low chronic post-COVID symptom burden. A substantial cluster of multisystemic symptoms was observed in both phases, and this condition highlights the requirement for customized outpatient management that includes long-term follow-up and treatment of COVID-19 patients. Identifying the high-risk patients that will develop persistent symptoms can guide this management.

Does Pneumococcal Vaccination Have an Effect on Hospital Costs?

OBJECTIVE: It is known that inpatient hospital costs are much higher than outpatient services. It was aimed to investigate the effect of pneumococcal vaccination on hospitalizations. MATERIAL AND METHODS: The direct hospitalization costs, length of stay, and factors of the vaccinated and unvaccinated patients in the same hospital during the 12-month follow-up of the patients who received pneumococcal vaccine between November 15, 2018, and November 15, 2020, in 3 chest diseases and thoracic surgery training and research hospitals were analyzed by obtaining Hospital Information Management System records. Data were collected with Statistical Package for the Social Sciences version 23 program (IBM Corp.; Armonk, NY, USA) , and statistical evaluation was made. RESULTS: The mean age of 800 hospitalized patients, of whom 400 were unvaccinated and 400 were vaccinated, was 68.48 ± 11.97. There was no significant difference in the mean age of vaccinated and unvaccinated patients (P > .05). Five hundred sixty-six patients (70.8%) were aged 65 and over. Two hundred eighty (51.2%) of men were vaccinated and 120 (47.2%) of women were vaccinated, and there was no significant difference (P > .05). The mean hospital stay of these patients was 11.01 days, and those in the vaccinated group had an average mean hospital stay of 9.11 days and those in the unvaccinated group had a mean hospital stay less than 12.91 days (P < .001). Total 1-year hospitalization costs were $501.653.53 and the cost per person was calculated as $627.07. The cost per capita for the vaccinated group was $550.52, which was lower than the average cost of the unvaccinated group ($703.62) (P < .05). When comparing the status of being vaccinated, comorbidity, mortality, mean length of stay, chronic obstructive pulmonary disease, and heart disease were found to be statistically significant (P < .05). CONCLUSION: In our study, it was revealed that vaccination of patients hospitalized in chest disease hospitals with the pneumococcal vaccine reduced the average length of hospital stay by 41.7% and the cost of hospitalization by 27.8%.

Place of vibration response imaging in preoperative lung cancer patients.

INTRODUCTION: In this study, we aimed to investigate the role of the vibration response imaging (VRI) as the second-line test in preoperative evaluation of the patients with non-small cell lung cancer (NSCLC) and in prediction of the predicted postoperative forced expiratory volume in one second (ppo FEV1). MATERIALS AND METHODS: A total of 31 patients scheduled for surgery underwent pulmonary function tests (PFTs), VRIxp and quantitative lung perfusion scintigraphy (LPS) in order to predict postoperative lung functions. PFTs and VRI were repeated between 4th and 6th postoperative weeks and FEV1 and FEV1% values were compared with preoperative VRI and ppo-FEV1 calculated with perfusion scintigraphy. Statistical analysis of 31 patients under postoperative follow-up was performed in two parts. In the first part, two preoperative prediction methods (ppo based on perfusion and ppo calculated with VRI), and in the second part, estimated values and postoperative actual values (considering postoperative spirometric values as standard) were compared. RESULTS: An agreement rate of 52% was found between the ppo values calculated with VRI and with perfusion. This rate was low, although respective predictive values for ppo VRI and ppo perfusion were 84% and 47%, suggesting that ppo VRI was more significant than LPS for prediction of the 1st month postoperative value in the patients included in this study. CONCLUSIONS: VRIxp has a high-accuracy rate in prediction postoperative FEV1. It is seemed as an alternative to quantitative perfusion scintigraphy for preoperative evaluation, because it can be easily applied at the bedside as a radiation free and non-invasive method.
