在社會環境中，直接與民眾健康有關的一個重要因素是衛生保健服務政策及其相應的供給體系，此一環節即是醫療體系。醫療專業與一般製造業相差甚遠，醫療活動的過程會因組織內部不同的專業、醫療技術、醫療儀器相關發展與疾病之不確定性因素而有所變動，因此醫療產業需要儲存與運用龐大資料，如大量的病患病歷資訊，相關之影像、聲音資料等。而醫療資訊系統之訴求乃以電腦有效處理病患資訊，若從基層醫療單位到醫學中心能夠整合醫療資訊，將可提供國民更為完善的醫療照護網路。
衛生所之處境處於醫療資源缺乏、財務緊繃，在缺乏相關資源的同時，卻又需要配合政府政策處理大量健康照護工作，因而利用資訊化的特性，減低成本支出與增加效率勢為最佳方案。
我國衛生署於92年開發之衛生所資訊系統雖提供保健、門診醫療、預防接種等行政作業弁遄A但均為各鄉鎮市區衛生所內部作業，並無相關強制使用等限制，因此普及率不甚理想。而少數衛生局自行開發保健系統，未與「衛生所資訊系統」整合，使得衛生所工作人員需重覆鍵入資料，造成工作負擔，因此該系統之推廣情況尚待加強。
本研究參考國外相關整合模式並採用瀑布模式分析衛生所資訊需求，列出資料流程圖、資料字典、資料庫設計與架構與系統整體流程圖，以Visual Basic開發結合SQL Server 2005，運用網際網路的特性，與網路服務元件之應用，建立以網路元件為基礎的架構，將衛生所之資訊系統分析與實做。
目前我國目前相關之軟體開發商、政府單位皆尚未將醫療服務與照護服務結合，醫療照護體系相關資訊系統也是以醫療服務為主。因此本研究期望藉由護理人員所需之追蹤照護與現行之醫療照護相關系統之連結，形成較過去更完整之個人及家戶健康照護，以落實個人健康、社區照護之理念。 In the social environment, an important factor in health service policy and system is health-care system. The professional healthcare industry has an obviously different with the manufacturing industry. The processes of medical activities different are due to the technology, equipment, professional or disease uncertainties. So, it is necessary for healthcare industry using a large amount of information technology and management such as patients related medical information, images and so on. Recently the main purpose of medical information system for patients is focus on medical service. If primary healthcare center can be integrated with the healthcare information of medical center, it will be able to provide a more comprehensive national healthcare service network.
Now the primary healthcare center in the situation of lack of medical resources and financial tension, but it stills need to support the policy of dealing with large health care work. Therefore, use the characteristics of information technology to reduce costs and increase efficiency is the best option.
The government health department development the information systems for primary healthcare center to improve healthcare, clinical and vaccination and other work in 1992. However the system belongs to internal operations and it does not require the mandatory use, so the penetration rate is not high. The few of self-developed healthcare system does not integration with primary healthcare information systems. This situation makes the staff of primary healthcare center need to duplicate entry the data. Therefore the system promotion needs to be improved.
In this research, the information need is analyzed for primary healthcare center by referred foreign-related integration model and waterfalls model of system analysis and design. In this paper, data flow diagram, data dictionaries, database design and structure and flow charts of each subsystem are included in system analysis and design for developing healthcare system of primary healthcare center. The developing tools are Visual Basic 6. and SQL Server 2005. So, it can work in the internet for developing present primary health information system by using web service components.
Now, the software developers and the government units in Taiwan have not yet combined the medical service and care service. The main topic of medical care system-related information system is focus on medical services. The study object of this research is combing the nursing care system for nursing system and the healthcare information system for primary healthcare center. This study purpose was to develop a more functional healthcare information system of individual and household. It would help to establish an integrated medical and healthcare network for community health care system in Taiwan.
