Towards Knowledge Intensive Inter-Organizational Systems in Healthcare 271 ChapterXV TowardsKnowledge Intensive Inter-Organizational Systems inHealthcare Teemu Paavola, LifeIT Plc, Finland and Helsinki University of Technology, Finland Pekka Turunen, University of Kuopio, Finland Jari Vuori, University of Kuopio, Finland Abstract The aim of this chapter is to share recent findings and understanding on how information systems can be better adopted to support new ways of work and improve productivity in public funded healthcare. The limits of transferring explicit and tacit knowledge are discussed and moreover, the chapter elaborates barriers to the widespread use of knowledge management tools among clinicians. The impacts of an inter-organizational system used for remote consultation between secondary and primary care providers are examined. Furthermore, the authors suggest that issues related to clinical knowledge management such as the varying information and knowledge processing needs of clinicians from various medical expertise domains should be examined carefully when developing new clinical information systems.

Although the blood of the deoxygenated blood from the fetus to the placenta, and mother and her offspring do not mix—each has its own one vein that carries oxygenated blood from the placenta blood and cardiovascular system—exchanges take place to the fetus (see Fig. In this manner, monary vessels, these arteries carry blood low in oxygen gases (CO2 and O2) are exchanged, nutrients are provided and this vein carries blood high in oxygen.

DEVELOPMENT AND BIRTH ✦ 481 Placental Hormones In addition to maintaining the riages (loss of an embryo or fetus) frequently occur dur- fetus, the placenta is an endocrine organ. Beginning soon ing this critical time when hormone secretion is shifting after implantation, some embryonic cells produce the from the corpus luteum to the placenta. This hormone stimulates creted by the placenta during pregnancy, reaching a peak the ovarian corpus luteum, prolonging its life-span to 11 at term, the normal conclusion of pregnancy. It promotes endometrial secretion to nourish the function leads to an alternate name for this hormone: embryo, maintains the endometrium and decreases the human chorionic somatomammotropin. By the end of the fourth month, the fetus By the end of the second month, the embryo takes on is almost 15 cm (6 inches) long, and its external genitalia an appearance that is recognizably human. By the seventh bryos, the primitive testes have formed and have begun to month, the fetus is usually about 35 cm (14 inches) long secrete testosterone, which will direct formation of the and weighs approxoimately 1.
