No full textInefficiency of service and the waiting time can occur in inpatient services, especially in VIP rooms. Reduction in waiting lists for patients entering the VIP room is carried out by increasing the bed capacity and the allocation of health workers. The study was conducted by modeling the service system in hospitalization, which began from the patient service at the Emergency Room (IGD) until service in the VIP room of a hospital in Sukabumi. The model was built with 2 scenarios, scenario 1 was designed to improve the performance of the IGD by adding beds and health workers so that patients had an alternative choice in class 1 before getting service in the VIP room, and scenario 2 was designed by not changing the system in the emergency room, but adding 10 VIP rooms. Scenario 2 is a solution and can visually improve the VIP service system by reducing the waiting time by 50.55 hours, with the investment value of net present value (NPV) > 0 and internal rate of return (IRR) 32.2%, against the Minimum Attractive Rate of Return (MARR) 12% per year profitable. Scenario 2 by adding 10 VIP rooms, initially 25 units to 35 units, effectively being able to produce improvements in significantly reducing the waiting list originally from 50.94 hours to 39 minutes there was a decrease (99.23%), and could reduce the utility level or busyness of service in VIP was originally 93.49% to 87.19%. From the results of NPV analysis > 0, and IRR 32.2% assuming MARR 12% per year, constructing 10 VIP rooms in 5 years can give a profit of 20.2% per year. Scenario 2 can be used as the basis for hospitals in making inpatient service system policies, especially in VIP rooms
Pengaruh Desain Stent pada Jumlah Limfosit dan Trombosit Kelinci (Oryctolagus Cuniculus)
No full textPercutaneous Coronary Intervention (PCI) is an effective treatment for coronary artery diseases. For the procedure, a stent is put in the coronary arteries. There are a variety of stent materials and designs available on the market. The development of stents continues with the goal to reduce the risk of failure. The design and the ability of the stent as a vascular scaffold are important factors for the success of the stent. The implantation of a stent as a foreign body can lead to inflammation. In general, the inflammation is characterized by an increased number of lymphocytes. Then, platelets play a role in coordinating the occurrence of inflammation and immune response. This study aims to determine the effect of stent design on the number of lymphocytes and platelets as a marker of inflammation. The study was conducted on ten rabbits divided into two treatment groups, namely KP1 (new design stent) and KP2 (commercial stent) by placing a stent on the iliac artery. One hour before stenting, 2 ml of blood was collected in all experimental animals. Then, 2 ml of blood was collected again on the 7th and 28th day after stenting. Data was collected based on the number of lymphocytes and platelets from all experimental animals. Statistical analysis using two-way ANOVA shows no significant difference (p> 0.05) on the number of lymphocytes and platelets between the two groups with different stent designs. It can be concluded that the design of a stent does not show a tendency to cause inflammation
