首诊医疗机构及其医务人员在接诊后,在最大限度保护患者生命健康的同时,对需要转院转诊的患者,除承担法定的转诊义务外,还要严格遵守转诊程序。按照相应的法律法规,正确合理地转院转诊,对于减少医疗纠纷,提高医疗质量有着重要的意义。本文着重分析转诊转院的法定义务和规范程序,并对特殊情况的转院转诊进行探讨。 相似文献

IntroductionWhen a patient is diagnosed with primary headache or craniofacial neuralgia in the emergency department or in primary care, and is referred to a neurologist due to the complexity of the case, it is useful to know whether additional examination should be sought and the priority (urgent, preferential or normal) with which the patient should be seen. This will avoid unnecessary delays in patients with disabling headache and where organic causes are suspected.In order to issue recommendations on this matter, the Spanish Society of Neurology's Headache Study Group has decided to create a series of agreed recommendations constituting a referral protocol for patients with headache and/or craniofacial neuralgia.DevelopmentYoung neurologists with an interest and experience in headache were invited to draft a series of practical guidelines in collaboration with Spanish Society of Neurology's Headache Study Group Executive Committee. For practical reasons, the document was divided into 2 articles: this first article focuses on primary headaches and craniofacial neuralgias and the second on secondary headaches. In order for the recommendations to be helpful for daily practice they follow a practical approach, with tables summarising referral criteria, examinations to be performed, and referral to other specialists.ConclusionsWe hope to offer a guide and tools to improve decision-making regarding patients with headache, identifying complementary tests to prioritise and referral pathways to be followed, in order to avoid duplicated consultations and delayed diagnosis and treatment. 相似文献

Objective: To analyse referral cohorts from School Entry Screening, Hearing (SHS) and Vision Screening (SVS) before and after documented changes. To compare referrals to pre-school specialists with subsequent group SHS outcomes. Design: Randomized cohort, audit analysis of Community Nursing Developmental and SES records (CHRs), plus Audiology file review for SHS referrals. Study sample: Six hundred and sixty-eight mainstream pupils’ CHRs were analysed in four birth cohorts, post-SES, using coded anonymized records. Results: Significant referral rate differences existed between SHS and SVS. SHS, not SVS, referrals were impacted by nursing staff changes but not by SHS protocol changes. Preschool Audiology referrals outnumbered SHS referrals. All PCHI children with amplification were detected prior to SHS. SHS program yielded conductive hearing loss only. Similar SHS referral rates occurred for pre-school Speech Language Therapy referrals compared to children not referred; just 16% of pre-school Speech Language Therapy primary referrals were referred on to Audiology. Conclusions: SHS referral percentage fell slightly; SVS referral percentage remained unchanged. Low referral rates and low SHS hearing loss yield has modest impact upon Audiology services, but audiometrically screened referrals deserve higher priority. UNHS children born after 2011 create bigger Audiology service impact. International comparisons and European SHS research collaboration are encouraged. 相似文献

Objective
Explore the perceived benefits of a Veterans Health Administration (VHA) geriatric specialty telemedicine service (GRECC Connect) among rural, older patients and caregivers to contribute to an assessment of its quality and value.Data Sources
In Spring 2021, we interviewed a geographically diverse sample of rural, older patients and their caregivers who participated in GRECC Connect telemedicine visits.Study Design
A cross-sectional qualitative study focused on patient and caregiver experiences with telemedicine, including perceived benefits and challenges.Data Collection
We conducted 30 semi-structured qualitative interviews with rural, older (≥65) patients enrolled in the VHA and their caregivers via videoconference or phone. Interviews were recorded, transcribed, and analyzed using a rapid qualitative analysis approach.Principal Findings
Participants described geriatric specialty telemedicine visits focused on cognitive assessments, tailored physical therapy, medication management, education on disease progression, support for managing multiple comorbidities, and suggestions to improve physical functioning. Participants reported that, in addition to prescribing medications and ordering tests, clinicians expedited referrals, coordinated care, and listened to and validated both patient and caregiver concerns. Perceived benefits included improved patient health; increased patient and caregiver understanding and confidence around symptom management; and greater feelings of empowerment, hopefulness, and support. Challenges included difficulty accessing some recommended programs and services, uncertainty related to instructions or follow-up, and not receiving as much information or treatment as desired. The content of visits was well aligned with the domains of the Age-Friendly Health Systems and Geriatric 5Ms frameworks (Medication, Mentation, Mobility, what Matters most, and Multi-complexity).Conclusions
Alignment of patient and caregiver experiences with widely-used models of comprehensive geriatric care indicates that high-quality geriatric care can be provided through virtual modalities. Additional work is needed to develop strategies to address challenges and optimize and expand access to geriatric specialty telemedicine. 相似文献27.

The purpose of this study was to conduct a needs assessment of a potential social service resource telephone program component among high risk youth who received the Project Towards No Drug Abuse (TND) classroom-based program (approximately 1 year earlier). Results supported youths' overwhelming receptiveness of a social service referral program. The vast majority of respondents indicated a strong desire for resource and referral information on vocational, educational, recreational, transportation, and mental health and drug counseling. Further research is needed to investigate the effectiveness of the provision of social service resource information on drug use among emerging adults. 相似文献

The aim of this study was to identify differences in the medical management and clinical outcome in a group of elderly patients admitted to a designated geriatric assessment unit (GAU) or to two general medical units (GMUs). A prospective randomised controlled trial was undertaken in 267 patients aged 70 years and over (mean age = 78.3 years). Following discharge from hospital, patients were followed up at three monthly intervals for a total of 12 months. At the time of discharge, no significant differences were found in inpatient management, length of stay, mortality rates, discharge rates to institutional care or utilisation of community services in patients admitted to the GAU and the GMUs. Similarly, no significant differences were found at three, six, nine, and 12 month follow up in case fatality, activities of daily living indices, mental health status, rates of institutional referral and the level of community service support in patients admitted to the GAU and the GMUs studied. These findings do not show any advantage for the unselected 70 + acutely ill elderly patient who is admitted to a designated geriatric assessment unit rather than to a general medical unit. Therefore, an admission policy to GAU, based solely on age 70 + is medically inappropriate and cost-inefficient. Evidence from other sources suggests that an age cohort of acutely admitted patients beyond 80 years may well have returned more optimistic findings for the GAU. In future, GAUs will require a more selective admission policy to maximise the benefits of their rehabilitative and interdisciplinary approach. (Aust NZ J Med 1991; 21: 230–234.) 相似文献
