Here in this article, we described the types of predictive modeling (Linear and Non-linear) used in medical research and how effectively the researchers take decisions based on predictive modeling, and what precautions, we have to take while building a predictive model.

Doctors’ use of medical mobile applications to access medical information has the potential to improve the use of their working time. Primary care physicians can use mobile applications to communicate with their patients, thereby improving the health of individual patients and the population as a whole. \u0000Objectives: The aim of the study is to determine the effectiveness of the use of medical reference mobile applications by general practitioners in their medical practice. \u0000Methods: The research was conducted through a sociological survey and a questionnaire survey. Descriptive statistics were used for the analysis. \u0000Results and Conclusions: The study found that in Ukraine, medical mobile applications are mainly reference, and their use allows doctors to improve decision-making and has a positive effect on the level of health of the population and the doctor’s working time management. The assessment of the duration of the appointment using applications showed that in most cases, the time of the consultation reduced to 15 minutes, which testifies to the improvement of this type of assistance to the population. Besides, the use of applications provides a significant reduction of the time for making a clinical decision by 5 minutes. We found a relationship between the average duration of the appointment, as well as the time for making a clinical decision and the frequency of using the mobile application during the working day. The hypothesis of a direct effect of an innovative approach (use of a mobile application) on the time of outpatient appointments by family doctors with a significance level of 0.05 was tested using statistical data analysis according to the Student's test. The presented results of the analysis of a medical experiment with general practitioners allowed drawing a conclusion about the positive impact of the use of mobile applications on the working time savings of general practitioners when providing medical services.","PeriodicalId":73480,"journal":{"name":"International journal of statistics in medical research","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-09-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44419243","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aims to determine the level of asthma control and its relationship with socio-demographic factors in asthma patients. \u0000Methods: This cross-sectional study was conducted between November 2020-April 2021 among people aged 18-64 who applied to the hospital and were not diagnosed with asthma. The data of the research were made with the personal information form, ACT (asthma control test). ACT is a questionnaire consisting of 5 questions. Patients rate each question between one and five points. The total score of the five questions forms the test result. If the total score is 25, it is considered as full control, 24-20 as partial control, and ≤19 as not under control. In the research, 206 people participated. \u0000Results: Of the participants, 60.7% were female, 60.2% had a family history of asthma, 94.2% of them used asthma medication, and the average age was 45.7±13.85. In the last 12 years, 50.5% of asthma patients stated that they applied to the emergency department due to respiratory problems, and 23.3% were hospitalized due to these problems. It was determined that 78.6% of asthma patients were not under control, 21.4% were under partial control, and there was no patient under full control. The mean age (48.8) and body mass index (BMI) (29.4) of those whose asthma was not under control were higher than those with partial control (32.2 and 24.7, respectively) (p<0.001). It has been determined that the probability of asthma not being controlled increases as age and BMI increase, and life satisfaction decreases, and it is higher in quit smokers than in current smokers (p<0.05). \u0000Conclusion: Asthma is largely uncontrolled. The rate of uncontrolled asthma increases with increasing age and BMI. Patients with high BMI should be supported to lose weight and should be directed to exercise.","PeriodicalId":73480,"journal":{"name":"International journal of statistics in medical research","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43751065","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

CDC's case-based surveillance system contains case-level information on most COVID-19 cases in the United States. Data analyzed in this paper contain COVID-19 cases with case-level information through September 25, 2020, which represent 70.9% of all COVID-19 cases reported to CDC during the period. Case-level surveillance data are used to investigate COVID-19 disparities by race/ethnicity, sex, and age. However, demographic information on race and ethnicity is missing for a substantial percentage of COVID-19 cases (e.g., 35.8% and 47.2% of cases analyzed were missing race and ethnicity information, respectively). Our goal in this study was to impute missing race and ethnicity to derive more accurate incidence and incidence rate ratio (IRR) estimates for different racial and ethnic groups, and evaluate the results from imputation compared to complete case analysis, which involves removing cases with missing race/ethnicity information from the analysis. Two multiple imputation (MI) models were developed. Model 1 imputes race using six binary race variables, and Model 2 imputes race as a composite multinomial variable. Our evaluation found that compared with complete case analysis, MI reduced biases and improved coverage on incidence and IRR estimates for all race/ethnicity groups, except for the Non-Hispanic Multiple/other group. Our research highlights the importance of supplementing complete case analysis with additional methods of analysis to better describe racial and ethnic disparities. When race and ethnicity data are missing, multiple imputation may provide more accurate incidence and IRR estimates to monitor these disparities in tandem with efforts to improve the collection of race and ethnicity information for pandemic surveillance.</p>","PeriodicalId":73480,"journal":{"name":"International journal of statistics in medical research","volume":"11 ","pages":"1-11"},"PeriodicalIF":0.0,"publicationDate":"2022-01-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8967240/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"10626657","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
