Abstract Background Peritoneal dialysis (PD) is the most common method of renal replacement therapy (RRT) in pediatric patients in Honduras. It has improved survival and quality of life. Unfortunately, there are complications associated with the use of PD catheters, 85% of which, are of infectious origin. These infections carry a high burden of morbidity and mortality, lengthen hospital stays, and increase costs and are a motive for transfer to hemodialysis. Hospital María Especialidades Pediátricas (HMEP) is a pediatric hospital caring for patients with chronic kidney disease in Honduras, PD has been offered as a method for RRT since September 2014. Methods In HMEP, monitoring of PD infection rates through active surveillance began December 1, 2017, as the first step (define and measure) toward the improvement of the PD Program based on Six Sigma methodology. A case of peritonitis was diagnosed when at least 2 of the following 3 criteria were met: (1) Clinical signs or symptoms of peritonitis (cloudy effluent or abdominal pain with fever or vomiting); (2) Altered peritoneal fluid cell count (after a dwell time of 2 hours: a WBC above 100 cells/mm3 in an uncentrifuged sample, with at least 50% neutrophils; or any WBC count with at least 50% neutrophils if the dwell time was less than 2 hours); (3) Positive peritoneal fluid culture. Patient data, risk factors for infection, causative organisms, and event outcomes were recorded. We present the main results of the analysis phase of all peritonitis cases using descriptive statistics. Results From December 1, 2017, through November 30, 2019, 79 patients required PD, representing 8931 catheter-days; and 30 peritonitis episodes occurred among 28 individuals (35%). The peritonitis rate during the 2-year surveillance period was 1.2 infections per patient-years (ideally: <0.67). Twenty-seven (90%) of cases were classified as healthcare associated since these patients underwent PD 3 times a week in the hospital and the catheter was only manipulated by medical staff; the other patients received dialysis at home. The median time from catheter placement to the event was 27 days (5–383 days). All patients had clinical signs or symptoms of peritonitis. Peritoneal fluid cell count results were available for 29 infections, all of which reported altered results. Peritoneal fluid cultures were positive in only 12 events (40%); 6 (50%) reported Gram-negative organisms, 5 (41%) reported Gram-positive and 1 reported Aspergillus spp. Nonfermentative Gram-negative bacteria (Pseudomonas aeruginosa and Acinetobacter lwoffii) were the most common organisms identified; Staphylococcus epidermidis was the most common Gram-positive. Ten events (33%) required removal and replacement of the catheter due to the infection, 6 (20%) required permanent transfer to hemodialysis; 2 (7.1%) patients experienced a relapse. Two (7.1%) died due to infection. Conclusions Implementing Six Sigma methodology allowed us to improve our PD Program by objectively quantifying the magnitude of the problem and identifying risk factors. This supported the infection prevention and control team with the implementation and improvement of preventive measures: change in hand hygiene products (from triclosan to chlorhexidine), increasing hand hygiene compliance, improving connection/disconnection procedure, PD catheter insertion, and maintenance, empowerment of caregivers.

Purpose This study aims to expand the current knowledge of the Six Sigma approach in a period of time when there is little direct evidence of the need to improve the credit card account opening process. This is an important but neglected area of focus in the Six Sigma literature. This study explores the extent to which process improvement practices are extended to the credit card department. Design/methodology/approach A case study methodology is adopted in this study to facilitate an exploration of the implemented Six Sigma approach in the credit card department of a leading commercial bank. The process improvement tool used is the define, measure, analyze, improve and control (DMAIC) cycle. Findings The study’s results confirm that the Six Sigma approach improves the quality of the credit card account opening process. So, the Six Sigma approach can account for a reduced number of keying-in errors, resulting in better data accuracy and improved customer satisfaction. Research limitations/implications The authors, in an attempt to render the study results more feasible for data collection, have chosen to focus on the process of the new accounts unit of the credit card department. Therefore, the authors have not taken into account the other units (e.g. transaction processing) of the same department. Practical implications The results of this study will be useful in persuading bank management to evaluate and implement the Six Sigma approach. Hence, this research will assist bank managers with replies to questions, such as: “What impact will Six Sigma have on process-centric improvement, such as the new accounts opening process of a credit card department?” Originality/value Within the literature on the Six Sigma practice, there is little research that focuses on the implementation of this particular toolset especially for credit card departments. This indicates a gap in the field. A new contribution to bridging that gap comes from the analysis of the results for the Six Sigma concept, which addresses the new accounts opening process.

The Impact

In the current scenario quality control became mandatory for all the sectors .This study is intended to examine the impact of internet facilities on students’ performance through a Blended Learning as a medium in an academic institution. It was examined, how the Blended Learning encompasses a variety of tools to create flexible, rich learning environments that stimulate learners and maximizes the potential for learning? Another objective is Application of Six Sigma methodology in this study is to improve the medium of learning i.e. internet connectivity through a set of procedures in an effective way. Six Sigma can be again viewed as a discipline or an approach driven by data and methodology for eliminating defects in any process- from manufacturing to transactional and from product to service.Keeping the aforesaid two objectives in mind, data was collected from a sample of 119 students residing in various hostel blocks using stratified random sampling technique. Questionnaire was developed after an extensive literature review to measure the impact of internet connectivity in Blended Learning of the students. The questionnaire to measure was based on the model developed by Shawn M. Glynn (2011).The scale was developed by referring to previous models developed by various authors to measure the impact of internet connectivity in the Blended Learning of the students. The statistical analysis used was reliability statistics, KMO, Bartlett’s test and Factor Analysis. The data was analyzed by SPSS version 20). We observed that application of Six Sigma methodology is useful to improve the medium of learning.DOI: http://dx.doi.org/10.3126/ijssm.v2i1.11520     Int. J. Soc. Sci. Manage. Vol-2, issue-1: 36-39
