Session 46: Description of Vaccines for Immunization ………………………………….297 PST 04211 Basic Pharmacology NTA Level 4 Semester 2 Facilitator Guide iii Background There is currently an ever increasing demand for pharmaceutical personnel in Tanzania. This is due to expanding investment in public and private pharmaceutical sector. Shortage of trained pharmaceutical human resource contributes to poor quality of pharmaceutical services and low access to medicines in the country (GIZ, 2012). Through Public-Private-Partnership (PPP) the Pharmacy Council (PC) together with Development Partners (DPs) in Germany and Pharmaceutical Training Institutions (PTIs) worked together to address the shortage of human resource for pharmacy by designing a project named “Supporting Training Institutions for Improved Pharmaceutical Services in Tanzania‖ in order to improve quality and capacity of PTIs in training, particularly of lower cadre pharmaceutical personnel. The Pharmacy Council formed a Steering committee that conducted a stakeholders workshop from 18th – 22ndAugust 2014 in Morogoro to initiate the implementation of the project. Key activities in the implementation of this project included carrying out situational analysis, curriculum review and harmonization, development of training manual/facilitators guide, development of assessment plan, training of trainers and supportive supervision. After the curricula were reviwed and harmonized, the process of developing standardised training materials was started in August 2015 through Writer‘s Workshop approach. The approach included two workshops (of two weeks each) for developing draft documents and a one-week workshop for reviewing, editing and formatting the sessions of the modules. The goals of writers workshops were to build capacity of tutors in the development of training materials and to develop high-quality, standardized teaching materials. The training package for pharmacy cadres includes a facilitator guide, assessment plan and practicum. There are 12 modules for NTA level 4 making 12 facilitator guides and one practicum guide. PST 04211 Basic Pharmacology NTA Level 4 Semester 2 Facilitator Guide iv Acknowledgment The development of standardized training materials of a competence-based curriculum for pharmaceutical sciences has been accomplished through involvement of different stakeholders. Special thanks go to the Pharmacy Council for spearheading the harmonization of training materials in the pharmacy after noticing that training institutions in Tanzania were using different curricula and train their students differently. I would also like to extend my gratitude to St. Luke Foundation (SLF)/Kilimanjaro School of Pharmacy –Moshi for their tireless efforts to mobilize funds from development partners. Special thanks to John Snow Inc (JSI), Deutsche GesellschaftFür Internationale Zusammenarbeit (GIZ), Merck Kgaa, BoehringerIngelheimGmbhand Bayer Pharma Ag and action medeor.V for the financial and technical support. Particular thanks are due to those who led this important process to its completion, Mrs Stella M. Mpanda Director, Childbirth Survival Intenational, and Members from the secretariat of National Council for Technical Education (NACTE) for facilitating the process. Finally, I very much appreciate the contributions of the tutors and content experts representing PTIs, hospitals, and other health training institutions. Their participation in meetings and workshops, and their input in the development of this training manual/facilitators guide have been invaluable.
