    In this thesis, we investigate the performance of a series of classification methods for the Prediction of the hospital Length of Stay (LoS) in Intensive Care Unit (ICU). Predicting LOS for an inpatient in an hospital is a challenging task but is essential for the operational success of a hospital. Since hospitals are faced with severely limited resources including beds to hold admitted patients, prediction of LoS will assist the hospital staff for better planning and management of hospital resources. The goal of this project is to create a machine learning model that predicts the length-of stay for each patient at the time of admission. MIMIC-III database has been used for this project due to detailed information it contains about ICU stays. MIMIC is an openly available dataset developed by the MIT Lab for Computational Physiology, comprising de-identified health data associated with ~40,000 critical care patients at Beth Israel Deaconess Medical Centre. It includes demographics, vital signs, laboratory tests, medications, and more. Different machine learning techniques/classifiers have been investigated in this thesis. We experimented with regression models as well as classification models with different classes of varying granularity as target for LoS prediction. It turned out that granular classes (in small unit of days) work better than regression models trying to predict exact duration in days and hours. The overall performance of our classifiers was ranging from fair to very good and has been discussed in the results. Secondly, we also experimented with building separate LoS prediction models built for patients with different disease conditions and compared it to the joint model built for all patients

    Background: Patients admitted to the Intensive care unit (ICU) receive multiple medications from a variety of pharmacological classes due to various life threatening illness and co-morbidities. The present study aims to evaluate the current usage of anti-microbial agents (AMAs) in the ICU of a teaching hospital in central India.Methods: A prospective observational study was carried out at the 11 bedded medical ICU of R. D. Gardi Medical College and Hospital, Ujjain (M.P.) for a period of 3 months from Aug 2012 to Oct 2012. The relevant data on drug prescription of each patients was collected from the inpatient case record. The demographic data, disease data and the utilization of different AMAs were analyzed.Results: A total of 1671 drugs out of which 343 AMAs were prescribed in 148 patients (male-78, female-70) studied, that is, an average of 11.3drugs/patients and 2.32 AMAs/patients. In ICU cefotaxime was the most commonly used AMAs in 17.5% patients, followed by metronidazole in 14% patients and ciprofloxacin in 8.8% patients. Most common indication for the anti-microbial therapy was infection (51.4%). 80.4% patients were given 1-3 AMAs, 19.6% patients were given 4-9 AMAs. amoxicillin+clavulanic acid was the most common FDC noticed.Conclusions: Interventional programme should focus on infection control with rational antibiotic prescription aimed at minimizing unnecessary cost, adverse drug reaction and emergence of bacterial resistance

    MANET is self configuring network. It has many design issues like scalability, energy consumption etc.In this paper, an overview of the Distributed mutual exclusion algorithm & various enhanced variations done on distributed mutual exclusion. In DME Permission-based algorithm is used for discovering clusters of the nodes. The initial point selection effects on the results of the algorithm, in the number of clusters found and their cluster headers. Methods to enhance the Permission-based clustering algorithm are discussed. With the help of these methods increase the concurrency between the nodes, decrease the synchronization delay and decrease response time. Some enhanced variations improve the efficiency and accuracy of algorithm. Basically in all the methods the main aim is to increase the life of each node in the network or increase the battery power which will decrease the computational time. Various enhancements done on DME are collected, so by using these enhancements one can build a new hybrid algorithm which will be more efficient, accurate and less time consuming than the previous work

    Background: To study the role of serum homocysteine and serum folate levels in prediction of materno-fetal outcome in preeclamptic women, especially in early onset preeclampsia.Methods: This prospective study was conducted in a tertiary care teaching hospital in India. 60 preeclamptic women (Group A) that were matched with 60 normotensive pregnant women (Group B), with singleton pregnancy and gestational age between 24-32 weeks attending antenatal clinics were included in the study. Maternal blood was collected twice first at time of enrolment and second at delivery. Serum homocysteine and serum folate levels were analyzed using enzymatic assay and chemiluminescent immunoassay. Mean rise in serum homocysteine and folate levels were calculated individually in all patients.Results: Mean homocysteine levels were significantly higher in Group A as compared to Group B both at enrolment and delivery (p 0.05).Conclusions: Serum homocysteine can be used as a reliable marker for predicting the severity of preeclampsia and adverse pregnancy (both maternal and fetal) outcome thus helps in reducing maternal and fetal morbidity and mortality, especially in women with early onset preeclampsia

    Background: Caesarean section rates have globally risen above the levels that can be considered medically necessary. The aim of the study is to analyze the rate and indications of caesarean sections for primigravidae in the period 2016 to 2018 at a tertiary care hospital in Delhi.Methods: It is a retrospective observational study conducted in the Department of Obstetrics and Gynaecology at PGIMER and Dr RML Hospital, New Delhi. A total of 552 caesarean deliveries in primigravidae were studied.Results: The total deliveries during the study period were 3346 and the total caesarean section rate observed was 30.66%. The caesarean section rate among primigravidae was 29.1%. The rate of caesarean section in primigravidae rose from 22.7% in 2016 to 39.3% in 2018 with 17% increase. Majority of them belonged to the age group 20-30 years (79.34%) and 2.53% were elderly primigravidae. Out of the total number of primigravidae caesarean deliveries, 67.2% were performed in emergency and 32.7% were performed electively. Among the emergency caesarean sections performed, 64% of patients had induced labor and 22% had spontaneous labor. The most common indication of caesarean section was fetal distress (19.77%) followed by arrest of labor (17.87%) and malpresentations (8.9%). The short-term caesarean morbidity rate was 25.4% including one mortality. Wound infection was the most common complication.Conclusions: Various reasons like changing maternal risk profile increased IVF pregnancies, scientific advances, personal choice and medico legal considerations have been cited for increased caesarean rate. Following evidence-based labor protocols, judicious use of cardiotocography, proper patient selection for labor induction and patient education will contribute in reduction of caesarean sections and related complications
