INTERNATIONAL JOURNAL OF SCIENTIFIC & TECHNOLOGY RESEARCH VOLUME 9, ISSUE 04, APRIL 2020 ISSN 2277-8616 2891 IJSTR©2020 www.ijstr.org e-VaccIMS: A Web-Based Vaccine Inventory Management In The Health Office Entrenching Forecasting Algorithm Mariannie A. Rebortera Abstract— The motivation of Expanded Programme on Immunization (EPI) of the World Health Organization was basic and direct which is to deliver various vaccines to all children through a basic timetable of child visits to the health centers to control and destroy vaccine-preventable diseases. Accuracy in forecasting vaccine demand is necessary to ensure normal operation during immunization. It is essential to often keep an inventory to guarantee continuous, accurate and timely delivery of the supply of vaccine so that quality standards are observed. However, in the City Health Office of Panabo City, Davao del Norte Philippines lacks the efficient and systematic way of managing inventory such as recording vaccine stocks and dispensing. It is time consuming in recording the incoming stocks manually and dispensing of the vaccine and record keeping of transactions are tedious. These processes are needed to guarantee accuracy in forecasting vaccine demand. Traditional way is prone to errors and inaccuracy. Thus, the development of a web-based inventory management for efficient transactions in receiving and dispensing of vaccine is conceptualized. The evaluation of the processes during the pilot testing of the said system achieves very good performance rating in monitoring the supply, ensuring consistency of the vaccine vial records and furnishing of report for efficient planning and control of vaccine. This means that the system met the objective and conforms to the user requirements. Furthermore, embedding the system to a vaccine demand forecasting algorithm is the future plan of this study.

Its motivation was basic and direct which is to deliver various vaccines to all children through a basic timetable of child visits to the health centers [1], [2], [3] established through routine immunization (RI) across nations that gives admittance to life sparing immunizations, prevents and abridged untimely death or a lifetime of disability [4], [5]. Immunization is acknowledged as one of the most successful public health interferences ever conceived [6] that helps control and destroy vaccine-preventable diseases [7], [8]. Inventory management of vaccine in the cold rooms and in the shelves will guarantee availability and accessibility for on-time immunization administration to infants and children [9]. Vaccines are temperature-sensitive [10], [3] products where shelf life is affected directly by temperature conditions. It is imported into the country to the national vaccine store, and then distributed until they reach health facilities. It is where vaccines are stored until they are used for immunization [6]. Outreach conveyance and health center visit are the two most applied immunization arrangement [11]. Careful attention is needed to ensure optimal potency of vaccines since cold chains is time-critical, complex and dynamic [12]. Storage and transport of vaccines are the important activity in the cold chain from the manufacturer through the primary vaccine store down to the outreach sites commonly at health centers. To ensure normal operation, it is essential to often keep an inventory to guarantee continuous and timely delivery of the supply of vaccine and quality standards are observed, otherwise, insufficient inventory causes shortage and disruption [13]. Managing inventory is the part of supply chain management that plans, implements and controls the efficient, effective, forward, and reverse flow and storage of goods, services, and related information between the point of origin and the point of consumption in order to meet consumer’s requirements [14] which in turn, if not given attention may results to instability of vaccines and inadequacy of supply in the routine and supplementary immunization schedules and the level of inventory should be optimized. In the Philippines, the lead of Routine Immunization (RI) for infants and children is through the ―Reaching Every Barangay (REB)‖ approach, a fine-tuning from the ―Reaching Every District (RED)‖ methodology of ―WHO-UNICEF‖, which expects to enhance the entrance of routine immunization and diminishing drop-outs. There are five (5) parts of the approach, to be specific: study of facts for action, re-create outreach services, fortifies connections amid groups and administrations, strong management and augmenting supplies. Additionally, the exactness of the estimates is vital - underestimating the supplies results in vaccine shortages, overestimating results in excess stock - increases the cost. Its significance relies upon the exactness - mulling over the kind of immunization, the presentation (vial size), the amount and the planning of delivery of the vaccine. Poor forecasting may bring about delays or shortages in delivery, extra expenses, and diminishes validity. Besides, keeping up vaccines at appropriate temperatures has turned out to be more perplexing on the grounds that some new vaccines loss its potency by freezing while others are harmed by heat exposure. Poor management of vaccines practices has huge financial consequences too [9]. The City Health Office (CHO) of Panabo City in particular is one of the most important entities who took charge of the vaccine cold chain and delivering immunization program and schedules to each of the forty (40) member barangays. CHO manages the receiving, dispensing and monitoring of each of the EPI vaccine. Insuffi cient inventory may cause shortages and result in the interruption of the program and delays immunization of affected infants/children. The inventory management of vaccine in CHO specifically the receiving and dispensing of vaccine stocks (i.e BCG, DPT, DPT-HepB-Hib, HepB, Measles, MMR, Polio, Pneumoccocal (PCV), Rotavirus and TT) are done manually. The current way of recording in the issuances ledger and the receiving of supply recorded in the stock card ————————————————  Mariannie A.
