Letters of recommendation for surgical residencies: what they say and what they mean.

Screening of applicants and selection of interns for surgical residency programs continue to rely heavily on letters of recommendation from surgical faculty. To define important aspects of letters useful for screening and selection, letters written on behalf of housestaff with known performance and those of new applicants were circulated to a sample of 120 academic surgeons. Eighty letters, written on behalf of 42 students, were divided into 10 groups of 8; each group was sent to 12 individuals. Half of the letters were "open" (full letter-head and signature), and half were "text only" (i.e., no identification). Candidate names were omitted. Each faculty reviewer was asked to rank the candidate represented by each letter, for their program, on a scale of 1 to 5, and indicate key negative or positive phrases on individual letters. Reviewers were also asked to indicate the importance they generally ascribe in evaluating such letters to the school of origin, academic rank of the letter writer, personalization (of letter to reader), formal vs informal reference to the candidate, and mention of interest in specialty training. A response rate of 60% was obtained. Faculty reviewers stated explicitly that school of origin, personalization of the letter, and the academic rank of the writer are important factors influencing their ranking of candidate letters. The scores they gave to "open" and "text only" letters, however, do not differ significantly (P > 0.05). Letters were scored similarly, indicating that school of origin or writer may not be as critical as implied or believed.(ABSTRACT TRUNCATED AT 250 WORDS)

Personality traits of surgical house officers: faculty and resident views.

Resident evaluation is highly subjective and continues to be a problem. Personality traits and characteristics account for 28% of factors considered; deficits in this area account for 22% of advanced residency terminations. Sixty-four faculty members and 51 residents in six university surgical departments were surveyed to determine differences in the perceived importance of 35 traits on a standard assertiveness scale. Each respondent was asked to score the importance of the traits on an unstructured list. Factors were then ranked in order of increasing mean score by group and compared. Traits with the lowest mean scores and least variance for both groups, indicating agreement, were: admits error, is well disciplined, considers all facts, is highly motivated and consistent, and listens. These are self-sufficiency and "internal discipline" traits. Nineteen of 35 traits had a mean score of 2.00 or less. For some general personality traits (e.g., decisiveness, fairness, good team participation, flexibility) there is excellent score and rank agreement, while others prompted disagreement (e.g., priority setting, independence, purposefulness). The correlation disagreement (e.g., priority setting, independence, purposefulness). The correlation between faculty and resident scores (r = 0.94) for all traits is excellent. "Independence" scored the greatest disagreement; residents ranked it 7 and faculty ranked it 14. Faculty and residents perceive similar traits as important and agree on their significance. Faculty select "like personalities" for their programs, supporting the notion of a "surgical personality." This personality is assertive in a positive manner.

Computerized drug dosing in renal failure: a real problem and a practical solution.

In the presence of impaired renal function a number of pharmacologic agents require dose adjustments to avoid toxicity. Physician dose variations of a wide range of pharmaceuticals, 237 orders for 30 drugs for 107 patients, were compared to doses recommended by a computer program which considers renal function in calculating its dose. Disagreement in dose regimens was evaluated by comparison of physician-dose to computer-dose for three classes of drugs: wide range, narrow range, and 80% renally excreted. With true renal impairment (serum creatinine greater than or equal to 1.2 mg/100 ml and creatinine clearance less than 80 ml/m) significant overdosing occurred for narrow range and 80% renally-excreted agents, 83 and 77% respectively. There is a great potential hazard observed to be avoided. It is recommended that dose adjustments for nephrotoxic or renally-excreted agents be implemented using creatinine clearance (estimated or measured) with, at the very least, manufacturer's recommendations.

Myxoma of bone. Report of three cases.

Three cases of myxomas of bone are presented. No similar tumor, except in bones of the jaw, was found in a study of more than 6,000 bone tumors in the files of the Mayo Clinic to Jan. 1, 1976. These three tumors were found in a series of about 5,000 lesions of bone in patients sent to the Mayo Clinic for consultation. All three of these tumors affected the femur. Care was taken to exclude lesions such as chondrosarcoma, fibrosarcoma, chondromyxoid fibroma, and ganglia of bone, all of which may contain prominently myxoid zones.

Computerization of the surgical intensive care unit: improvement of patient care via education.

For the past 18 months we have been evaluating and developing a computerized patient-monitoring system in our surgical intensive care unit. Despite the enormous potential for use of such systems, we have been impressed with its underutilization and its failure to yield objective improvement in patient care at our institution and many others. The output of the system was ignored because the decision maker was unable or unwilling to integrate the more sophisticated data presented to him. The computer was relegated to the position of "redundant secretary". In an attempt to reverse this situation, we have developed a multilevel, multigoal educational system employing the computer. We have implemented brief educational programs for use by all unit personnel to explain deviant monitored variables. Given a physiologic subsystem and a particular variable, personnel can: (1) inquire whether or not the variable is deviant; (2) obtain a list of probable causes for the deviation; (3) obtain an explanation of the pathophysiology of particular deviants as well as instruction on how to identify a most probable cause; and (4) inquire how to correct specific deviants. When we monitored the system utilization after implementation of the educational programs, we found all of the system had improved utilization. As a result we have a better educated staff who communicate more effectively, deal with more sophisticated information, and make better decisions with resultant improved patient care. Additionally, the staff is eager to help improve the system. We believe the full potential of such systems can be obtained only through education.

Ultradian cardiac rhthms in surgical intensive care unit patients.

Several reports have suggested that heart rate may be regulated by an ultradian biological rhythm with a period of about 90--100 min. Blood pressure and heart rate were collected from 10 Surgical Intensive Care patients at 5-min intervals and analyzed by computer. No 90-min rhthms were found, indicating this rhythm has no significant influence on heart rate or blood pressure in postsurgical patients.
