Integrating public health into medical education: community health projects in a Primary Care Preceptorship.

Physicians must integrate care of populations with the care of individual patients to function optimally in today's health care environment. With this understanding, medical school curricula are increasingly addressing the skills and knowledge of public health along with those of clinical medicine. The University of Utah School of Medicine in 1997 revised its four-year curriculum to increase the teaching of topics needed by future physicians, including public health. This report describes one course in the curriculum, the Primary Care Preceptorship (PCP), a fourth-year, six-week required rotation that assists students in learning about the health needs of a community along with providing primary care for its individual residents. Students in the PCP spend approximately 60% of their time in clinical primary care and 40% completing a community health project. In the first year of the PCP, 32 students completed projects on clinical problems, 27 on community health needs assessment, 26 on patient education, and 15 on epidemiology.

Prospective evaluation of topical versus retrobulbar anesthesia: a converting surgeon's experience.

PURPOSE: To evaluate and compare the efficacy of topical versus retrobulbar anesthesia for cataract surgery performed by a surgeon newly converting to the topical technique. SETTING: Department of Ophthalmology, Moran Eye Center, University of Utah, Salt Lake City, Utah, USA. METHODS: Ninety patients were prospectively assigned by permuted block restricted randomization to receive topical (Group 1; n = 45) or retrobulbar (Group 2; n = 45) anesthesia. Group 1 received topical bupivacaine 0.75% and intravenous midazolam and fentanyl for anesthesia. Group 2 received intravenous methohexital followed by retrobulbar block with an equal mixture of lidocaine 2% and bupivacaine 0.75% plus hyaluronidase 150 units. A visual pain analog scale was used to assess the degree of pain during anesthesia administration and surgery and postoperatively. The degree to which eye movement, touch, and light caused patient discomfort was assessed. Intraoperative conditions and complications were recorded. RESULTS: Intraoperative operating conditions were significantly better in Group 2 (P < .05). There was a small but statistically significant difference in the degree of discomfort during anesthesia administration and surgery (P < .05). There was no difference in postoperative discomfort. Chemosis, subconjunctival hemorrhage, and eyelid hemorrhage occurred only in Group 2, in which there was one retrobulbar hemorrhage. Although eyelid squeezing and ocular motility were present more frequently in Group 1, neither was a problem to the surgeon. CONCLUSION: Cataract surgery was safely performed by a surgeon converting to topical anesthesia. After a distinct learning curve, the procedure was performed with minimal patient discomfort. Surgical training and patient preparation are the key to safe use of topical anesthesia.

A comparison of topical and retrobulbar anesthesia for cataract surgery.

PURPOSE: To evaluate and compare the efficacy of topical and retrobulbar anesthesia for cataract extraction with intraocular lens implantation. METHODS: One hundred thirty-eight patients prospectively were assigned to the topical (group 1; n = 69) or retrobulbar (group 2; n = 69) anesthesia groups by permuted block restricted randomization. Group 1 received topical 0.75% bupivacaine and intravenous midazolam and fentanyl for anesthesia. Group 2 received intravenous methohexital followed by retrobulbar block with an equal mixture of 2% lidocaine and 0.75% bupivacaine plus hyaluronidase (150 U). A visual pain analogue scale was used to assess the degree of pain during the administration of anesthesia, during surgery, and post-operatively. The degree to which eye movement, touch, and light caused patient discomfort was assessed. Complications and surgical conditions were recorded. RESULTS: There was no difference in the surgical conditions (P = 0.5) or pain during surgery (P = 0.35) between the two groups. There was more discomfort during administration of topical anesthesia (P < 0.0001) and postoperatively (P < 0.05) in the topical group. Chemosis, subconjunctival hemorrhage, and eyelid hemorrhage were seen almost exclusively in the retrobulbar group. One patient in group 2 had a retrobulbar hemorrhage. Although eyeball movement and squeezing of the eyelids were present more frequently in the topical group, neither was a problem to the surgeon. CONCLUSION: Topical anesthesia can be used safely for cataract extraction. The degree of patient discomfort is only marginally higher during administration of the anesthesia and postoperatively. However, surgical training and patient preparation are the keys to the safe use of topical anesthesia.
