"特色医疗技术"概念探讨

鉴于我国医疗界对“特色医疗技术”尚未形成统一概念的状况,从“特色医疗技术”的内涵着手,对“特色医疗技术”的概念进行了探讨。同时提出,发展特色医疗技术要遵循“三原则”,即解放思想、以市场需求为牵引、结合实际;拓宽“三渠道”,即加强技术创新、科研成果转化、引进和改造技术;做好“三配套”工作:即加大组织工作力度,注重人才培养,加强信息网络建设。以此促进特色医疗技术的发展,提升医院核心竞争力。     

Can computers improve patient care by primary health care workers in India?

OBJECTIVE: The objective was to test whether a decision support technology for non-physicians can increase health care utilization and quality. DESIGN: Before and after measurements were taken from a systematic random sample of patients and staff at randomly assigned intervention and control facilities. SETTING: The study took place at primary health facilities in rural Tamil Nadu, India. PARTICIPANTS: One thousand two hundred and eighty-six patients and 82 staff were interviewed. INTERVENTION: A computer-assisted decision support technology was introduced to assist with patient screening. MAIN OUTCOME MEASURES: Outcome measures included new patient visits per month, a Global Patient Assessment of Care Index, and health worker attitude variables. RESULTS: There was a difference of difference of 430 new patient visits per month at the intervention sites (P = 0.005), an increase from baseline of 18% at intervention sites compared with a decline of 5% at control sites. The intervention was associated with significant improvements in a Global Patient Assessment of Care Index (mean difference of difference 7.9, P < 0.001). The largest gains were made in patient communication, technical quality, and general satisfaction with care. The attitudes of public health workers toward the new technology and their jobs did not change. CONCLUSIONS: Decision support technologies have considerable potential to improve coverage and quality of health care for the poor and where there is no doctor, but the unreceptive attitude of public health workers would need to be overcome. Application of these technologies should take advantage of their popularity with patients and the opportunity to work through the private sector.
