An analysis of trends, perceptions, and use patterns of electronic medical records among US family practice residency programs.

BACKGROUND AND OBJECTIVES: This study intended to quantify electronic medical record (EMR) use in family practice residencies, associate program characteristics with EMR use, and identify perceptions and issues about the use of EMRs. METHODS: A survey was mailed to all 454 US family practice residency programs, with a 72% response rate. The survey, which was pretested and revised, was designed to identify benefits, problems, perceptions, and trends regarding the use of EMRs. RESULTS: Fifty-five of 329 programs (17%) were using an EMR, while 10 (3%) had used an EMR but discontinued. Programs in the South reported the highest EMR use (21%, 21/99), and those in the North Central region reported the lowest use (11%, 11/102). EMR use was highest in university settings (19%, 15/81), programs offering fellowships (26%, 24/92), new programs (36%, 18/48), and programs that require research (22%, 20/91). Of the 329 programs that responded, 43% (143 programs) reported having information systems (IS) committees. Of the 55 programs currently using EMRs, 78% had at least one full-time equivalent IS technician. Of programs that discontinued use, software inadequacy was the most frequently cited reason (40%, 4/10). Programs that had never used EMR systems (n = 264) were more likely than those that had used EMRs (n = 65) to favorably perceive EMRs with respect to 1) meeting program requirements (44% versus 34%), 2) documenting improved patient care (65% versus 43%), 3) providing a reliable research database (94% versus 55%), and 4) documenting resident experience (92% versus 53%). Of the 264 (80%) programs that had never used an EMR, 172 (65%) plan to implement one. CONCLUSIONS: EMR use is low among US family practice residency programs, but some success in implementation of EMRs has been achieved. Based on the responses to this survey, use will likely increase from 55 of 329 programs (17%) to 153 of 329 (47%) by 2000.

A decision analysis to guide antibiotic selection for Chlamydia infection during pregnancy.

OBJECTIVE: To analyze the cost and effectiveness of different antibiotic combinations for the treatment of infection with Chlamydia trachomatis in pregnant women. METHODS: Using availability treatment effectiveness rates from the literature, a decision analysis model was constructed to determine the effectiveness and cost of therapy with 4 antibiotics shown to be useful for Chlamydia infection during pregnancy. Women who were still infected after initial therapy were then treated with a second antibiotic. Outcomes included the total cost of the treatment (including pretreatment and posttreatment cultures and antibiotic cost) and treatment failure rates. RESULTS: The lowest failure rates could be achieved with the use of amoxicillin followed by azithromycin for treatment failures or azithromycin followed by clindamycin hydrochloride. When costs were compared, a strategy starting with amoxicillin followed by azithromycin for nonresponders was favored, with costs approximately 15% lower than starting with azithromycin followed by amoxicillin. Strategies using clindamycin were significantly more expensive. The drug combination recommended by the Centers for Disease Control and Prevention (erythromycin followed by amoxicillin in nonresponders) was more expensive than amoxicillin-azithromycin and had one of the highest failure rates. Variation in the cost of the medications and in the effectiveness of the antibiotics under consideration did not significantly alter the findings. CONCLUSIONS: For pregnant women infected with Chlamydia, initiating treatment with amoxicillin, 500 mg 3 times a day for 7 days, followed by a single 1-g dose of azithromycin for nonresponders is the most cost-effective strategy for treatment.

Local anesthesia for circumcision: which technique is most effective?

BACKGROUND AND OBJECTIVES: Circumcision is the most commonly performed surgical procedure in the United States, and it is painful. Several investigators have independently documented the reliability and safety of local anesthesia in eliminating the pain associated with circumcision. Investigations have not, however, been conducted to determine which technique is most effective in reducing the pain of the procedure. This study compares the techniques of local anesthesia for circumcision to determine which technique most safely and reliably reduces pain. METHODS: Fifty-six infants being circumcised were randomly assigned to one of three groups according to anesthesia technique: (1) distal branch block, (2) root block, and (3) subpubic block. Change in heart rate and oxygen saturation, as well as cry response, were recorded. Heart rate and oxygen saturation differences were analyzed utilizing Student's t test, whereas cry response was analyzed using the chi-square test. RESULTS: We discontinued using the distal branch block technique during the study because we were concerned about possible untoward outcomes. As a result, only data from the circumcisions of the 42 infants who were assigned to the root block and subpubic block groups were analyzed. The dorsal penile nerve root block more reliably reduced the pain of circumcision than did the subpubic technique (P = 0.05). There were no serious complications with any of the techniques in this study. CONCLUSIONS: Compared with distal branch block and subpubic block techniques, nerve block at the penile root most reliably and safely eliminated the pain of circumcision.
