Experiential and authentic learning approaches in vaccine management

A high level of concern is placed on the storage, handling, transportation, and distribution of vaccines and other pharmaceutical products, particularly those that are time and temperature sensitive. While active and passive cooling equipment and monitoring devices are important, it is the various personnel responsible for executing and writing procedures, designing and operating systems, and investigating problems and helping prevent them who are paramount in establishing and maintaining a “cold chain” for time and temperature sensitive pharmaceutical products (TTSPPs). These professionals must possess the required competencies, knowledge, skills and abilities so they can effectively perform these activities with appropriate levels of expertise. These are complex tasks that require the development of higher cognitive skills that cannot be adequately addressed through professional development opportunities based on simple information delivery and content acquisition. This paper describes two unique learning solutions (one on a bus called the “wheels course” and the other online called “e-learning”) that have been developed by WHO Global Learning Opportunities (WHO/GLO) to provide participants with opportunities not just to learn about cold chain systems or vaccine management, but, rather, to develop high levels of expertise in their respective fields through experiential and authentic learning activities. In these interactive learning environments, participants have opportunities to address real-life situations in contexts similar to what they may face in their own work environments and develop solutions and critical thinking skills they can apply when they return to their jobs. This paper further delineates the managerial and operational vaccine management functions encompassed in these two unique learning environments. The paper also describes the alignment of the objectives addressed in the “wheels course” and the e-learning version with effective vaccine management (EVM) criteria as prescribed by WHO. The paper concludes with an example of a real world product developed by course graduates (specifically a decision tree that is now used by some national programmes). These types of products, valuable in their own right, often emerge when learning environments based on authentic learning principles are designed and implemented as they were by WHO/GLO

Analysis of patients admitted to the emergency unit of a university children's hospital in Turkey

A retrospective analysis of the computerized data of patients admitted to our Emergency Unit Inpatient Service in 1991 was conducted to obtain data about age, sex, referred sources, admission period, monthly admission rates, diagnoses and eventual outcome. More than 47% of patients were younger than one year of age. The most common causes for hospital admission were infectious, respiratory and neurological diseases. The mean hospitalization period was 3.26 days. More than 60% of patients were treated by the Emergency Unit staff. The net mortality rate was 2.9%, infectious diseases being the most common cause of mortality. We conclude that demographic and diagnostic data regarding admissions to the Emergency Unit can be utilized to develop new strategies for patient care and to reorganize education programs for pediatric residents

THE IMPACT OF SYSTEMATIC USE OF ORAL REHYDRATION THERAPY ON OUTCOME IN ACUTE DIARRHEAL DISEASE IN CHILDREN

A review of our experience with diarrheal disease (DD) at the University of Istanbul Children's Hospital in Capa, covering the years 1987 to 1989, is presented in this paper. DD is one of the most common conditions encountered among patients presenting to the outpatient clinic (5.9% of all cases)

Assessing the potency of oral polio vaccine kept outside of the cold chain during a national immunization campaign in Chad

This study is the first systematic documentation of the potency of monovalent oral polio vaccine type 3 (mOPV3) kept at ambient temperatures during a polio immunization campaign in Chad. During the study test vials were exposed to temperatures of up to 47.1 degrees C, and kept outside of the 2-8 degrees C range for a maximum of 86.9 hours. Post-campaign laboratory testing confirmed that the test vials were still potent, and in conformity with the defined release specifications. Further, the Vaccine Vial Monitors performed as expected, giving an early warning indication of when cumulative exposure to heat reached levels that may have negatively affected the vaccine&#039;s potency. This study provides proof-of-concept evidence that certain types of OPV remain potent and thus can be kept, for limited periods of time, as well as administered at ambient temperatures</p
