Objective Consensus that enhanced teamwork is necessary for efficient and effective primary care delivery is growing. We sought to identify how electronic health records (EHRs) facilitate and pose challenges to primary care teams as well as how practices are overcoming these challenges.Methods Practices in this qualitative study were selected from those recognized as patient-centered medical homes via the National Committee for Quality Assurance 2011 tool, which included a section on practice teamwork. We interviewed 63 respondents, ranging from physicians to front-desk staff, from 27 primary care practices ranging in size, type, geography, and population size.Results EHRs were found to facilitate communication and task delegation in primary care teams through instant messaging, task management software, and the ability to create evidence-based templates for symptom-specific data collection from patients by medical assistants and nurses (which can offload work from physicians). Areas where respondents felt that electronic medical record EHR functionalities were weakest and posed challenges to teamwork included the lack of integrated care manager software and care plans in EHRs, poor practice registry functionality and interoperability, and inadequate ease of tracking patient data in the EHR over time.Discussion Practices developed solutions for some of the challenges they faced when attempting to use EHRs to support teamwork but wanted more permanent vendor and policy solutions for other challenges.Conclusions EHR vendors in the United States need to work alongside practicing primary care teams to create more clinically useful EHRs that support dynamic care plans, integrated care management software, more functional and interoperable practice registries, and greater ease of data tracking over time. 相似文献

Single course versus maintenance bacillus Calmette-Guerin therapy for superficial bladder tumors: a prospective, randomized trial 总被引:1,自引:0,他引:1
M A Hudson T L Ratliff D P Gillen E O Haaff S M Dresner W J Catalona 《The Journal of urology》1987,138(2):295-298
A total of 42 patients with recurrent superficial bladder tumors or carcinoma in situ entered a prospective, randomized trial to compare the efficacy of bacillus Calmette-Guerin therapy with and without quarterly maintenance instillations of bacillus Calmette-Guerin. Maintenance therapy did not reduce further bladder tumor recurrence rates or the interval to recurrence in patients who responded to the initial course of therapy. However, prolongation of toxicity was observed with maintenance bacillus Calmette-Guerin therapy. 相似文献

The use of trichloracetic acid in the treatment of decorative tattoos is described. The technique is simple to perform. No anaesthesia or analgesia is required. Complications are uncommon and usually minor. Trichloracetic acid acts by inflicting a chemical burn. 相似文献

The authors describe four cases in which obstructive sleep apnea complicated the course and treatment of mania. An association between weight gain, obstructive sleep apnea, and lithium treatment is also illustrated. 相似文献

A technique is described in which superficial musculoaponeurotic system (SMAS) is plicated from the deep temporal fascia
above the zygoma to the level of the earlobe. This procedure requires only an extended preauricular incision. The neck is
dealt with by liposuction. This technique is ideally suited to the younger patient requesting facelift and is based on a sound
understanding of the anatomy of SMAS. The outcome of 35 patients who underwent this procedure during a 3.5-year period are
described. There were no cases of facial nerve paresis or hair loss. There were no cases of skin necrosis but two patients
developed small hematomas and one patient complained of a stretched preauricular scar. The mini facelift leads to a satisfactory
result in the younger patient requesting rhytidectomy. The technique is simple and safe and can easily be performed on an
ambulatory basis. Complications are uncommon and of a minor nature. 相似文献

We have reported a rare case of acute large bowel obstruction complicating acute pancreatitis. The diagnosis of pancreatitis is often initially not considered in such patients, and is established only at laparotomy. The splenic flexure is the most common site of large bowel involvement. A proximal defunctioning colostomy is the preferred primary management. 相似文献

Flexor tendon injuries in adults differ from those in children. 38 children (22 male and 16 female) with a mean age of 6.7 years were treated for flexor tendon injuries by primary suture and controlled mobilization between 1985 and 1992. 53 flexor tendons were injured (average 1.5 digits per patient) and the injury most commonly affected the little finger (23 patients). 60% of injuries occurred in zone 2. Using Lister's criteria, 82% achieved excellent or good results. Repair of both FDS and FDP was better than repair of FDP alone, even in zone 2. There were three tendon ruptures(all classified as poor results) and one other poor result occurredin a zone injury with an associated ulnar nerve palsy. The outcome after flexor tendon repair in children is better than in adults in our hands because rapid healing of tendons occurs in children. No child has yet required tenolysis because in children adhesions are more pliable. Both flexor tendons should be repaired irrespective of the zone of injury. A functional hand can be expected after flexor tendon repair in children. 相似文献
