Although the clinical (operating room) production of individual anesthesiologists has been measured in multiple related ways (e.g., hours of direct clinical care), the same is not true for the quality of that effort. In our study, we consider the quality of clinical supervision provided by anesthesiologists who are supervising anesthesia residents and nurse anesthetists. The quality of the daily supervision can be measured reliably and validly using the scale developed by de Oliveira Filho et al. If clinical production and supervisory quality were not positively correlated, then it would be important for departments to measure the quality of clinical supervision because, essentially, the clinical value provided by an anesthesiologist would be correlated with, but not necessarily proportional to, their clinical hours.
Our department sends daily e-mail requests to anesthesia residents and nurse anesthetists to evaluate the supervision provided by each anesthesiologist with whom they worked the previous day in an operating room setting. We compared anesthesiologists' clinical activity (total operating room hours) and supervision scores obtained during the first (July 1, 2013 to December 31, 2013) and last (July 1, 2014 to December 31, 2014) of 3 consecutive 6-month periods. During the first 6 months, anesthesiologists received no feedback regarding the supervision scores. During the last 6 months, there was feedback to all anesthesiologists regarding their individual supervision scores and comments provided by residents (during the preceding 6 months) and nurse anesthetists (during the preceding 12 months).
Anesthesiologists' mean supervision scores were not positively correlated with their total (weekly) hours of clinical activity. For the first 6 months, the correlations were r = -0.18 among scores provided by residents (P = 0.92 for positive correlation, N = 57 anesthesiologists) and r = -0.04 among scores provided by nurse anesthetists (P = 0.70, N = 61). For the last 6 months, the correlations were r = -0.28 (P = 0.98) and r = -0.10 (P = 0.79), respectively. Pairwise by anesthesiologist, the mean supervision scores provided by residents increased by 0.08 ± 0.01 points (P < 0.0001, N = 44). The mean supervision scores provided by nurse anesthetists increased by 0.28 ± 0.02 points (P < 0.0001, N = 49).
When anesthesiologists supervise anesthesia residents and nurse anesthetists, the amount of clinical work performed and the quality of the supervision provided do not necessarily follow one another. Thus, faculty supervision scores serve as an independent measure of the contribution of an individual anesthesiologist to the care of the patient. Furthermore, when supervision quality is monitored and feedback is provided to anesthesiologists, quality can increase. The results suggest that anesthesiology department managers should not only be monitoring (and perhaps reporting) the quality of their departments' level of supervision, but also establishing processes so that individual anesthesiologists can learn about the quality of supervision they provide.
This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 25 July 2015.
All research outputs
#27,727,448
of 34,361,833 outputs
Outputs from Anesthesia and analgesia
#9,496
of 10,893 outputs
Outputs of similar age
#221,557
of 300,508 outputs
Outputs of similar age from Anesthesia and analgesia
#63
of 82 outputs
Altmetric has tracked 34,361,833 research outputs across all sources so far. This one is in the 16th percentile – i.e., 16% of other outputs scored the same or lower than it.
So far Altmetric has tracked 10,893 research outputs from this source. They typically receive more attention than average, with a mean Attention Score of 7.7. This one is in the 10th percentile – i.e., 10% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 300,508 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 22nd percentile – i.e., 22% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 82 others from the same source and published within six weeks on either side of this one. This one is in the 20th percentile – i.e., 20% of its contemporaries scored the same or lower than it.
