BACKGROUND: Globally, pulmonary tuberculosis is a significant public health and social problem. OBJECTIVE: We investigated the factors influencing the hospitalization cost of patients with pulmonary tuberculosis and grouped cases based on a decision tree model to provide a reference for enhancing the management of diagnosis-related groups (DRGs) of this disease. METHODS: The data on the first page of the medical records of patients with the primary diagnosis of pulmonary tuberculosis were extracted from the designated tuberculosis hospital. The influencing factors of hospitalization cost were determined using the Wilcoxon rank sum test and multiple linear stepwise regression analysis, and the included cases were grouped using the chi-squared automated interaction test decision tree model, with these influential factors used as classification nodes. In addition, the included cases were grouped according to the ZJ-DRG grouping scheme piloted in Zhejiang Province, and the differences between the two grouping methods were compared. RESULTS: The length of hospital stay, respiratory failure, sex, and age were the determining factors of the hospitalization cost of patients with pulmonary tuberculosis, and these factors were incorporated into the decision tree model to form eight case combinations. The reduction in variance (RIV) using this grouping method was 60.60%, the heterogeneity between groups was high, the coefficients of variance ranged from 0.29 to 0.47, and the intra-group difference was small. The patients were also divided into four groups based on the ZJ-DRG grouping scheme piloted in Zhejiang Province. The RIV using this grouping method was 55.24, the differences between groups were acceptable, the coefficients of variance were 1.00, 0.61, 0.77, and 0.87, respectively, and the intra-group difference was significant. CONCLUSION: When the pulmonary tuberculosis cases were grouped according to the duration of hospital stay, respiratory failure, and age, the results were rather reasonable, providing a reference for DRG management and cost control of this disease.

BACKGROUND: Patients who have been treated with mechanical ventilation for more than 72 hours are susceptible to symptoms such as hypoxia and respiratory muscle fatigue after weaning, which may result in weaning difficulty and delay, as well as an increased incidence of negative emotions such as anxiety and depression. Correct pulmonary rehabilitation exercise technique and timing can improve the weaning success rate, reduce the disability rate, and reduce the incidence of pulmonary infection, as well as reduce medical expenses. OBJECTIVE: This article provides a review of pulmonary rehabilitation interventions for mechanically ventilated patients, searching relevant literature through databases such as CNKI and PubMed, aiming to provide guidance for the successful weaning of mechanically ventilated patients. METHODS: We selected articles related to pulmonary rehabilitation interventions for mechanically ventilated patients from CNKI (China National Knowledge Infrastructure) and PubMed over the years. RESULTS: This article provides a comprehensive review of the research on lung rehabilitation for patients who are mechanically ventilated during the weaning process in an effort to serve as a guide for a successful transition from mechanical ventilation. CONCLUSION: Early pulmonary rehabilitation training can effectively increase the pulmonary function level and ventilation function of patients and reduce the duration of mechanical ventilation and hospitalization, and is an effective, safe, and feasible treatment method.

Objective: Compared to younger patients with tuberculosis (TB), elderly and senile-aged patients with TB had a higher incidence of adverse outcomes particularly in terms of lost to follow-up and deaths. Our study aimed to gain insight into the effectiveness of anti-tuberculosis (anti-TB) treatment in the elderly or senile-aged patients and identify the risk factors for adverse outcomes. Methods: The case information was obtained from the "Tuberculosis Management Information System". From January 2011 to December 2021, this retrospective analysis was conducted in Lishui City, Zhejiang Province to observe and record the outcomes of elderly patients diagnosed with TB who agreed to receive anti-TB and(or) traditional Chinese medicine(TCM) treatment. We also employed a logistic regression model to analyze the risk factors for adverse outcomes. Results: Among the 1191 elderly or senile-aged patients with TB who received the treatment, the success rate was 84.80% (1010/1191). Using logistic regression analysis, several risk factors for adverse outcomes (failure, death, loss to follow-up) were identified, including age ≥ 80 years (OR 2.186, 95% CI 1.517~3.152, P< 0.001), lesion area ≥ 3 lung fields (OR 0.410, 95% CI 0.260~0.648, P< 0.001), radiographic lesions failing to improve after 2 months of treatment (OR 2.048, 95% CI 1.302~3.223, P=0.002), sputum bacteriology failing to turn negative after 2 months of treatment (OR 2.213, 95% CI 1.227~3.990, P=0.008), lack of a standardized treatment plan (OR 2.095, 95% CI 1.398~3.139, P< 0.001), and non-involvement of traditional Chinese medicine (OR 2.589, 95% CI 1.589~4.216, P< 0.001). Conclusion: The anti-TB treatment success rate in the elderly and senile-aged patients is suboptimal. Contributing factors include advanced age, extensive lesions, and low sputum negative conversion rate during the intensive treatment phase. The results will informative and could be useful for policy maker for to control of reemergence of TB in big cities. [ABSTRACT FROM AUTHOR]
