Abstract

Background

Despite its multifaceted importance, no validated or reliable tools assess the quality of the dictated operative note. This study determined the construct validity, interrater reliability, and internal consistency of a Structured Assessment Format for Evaluating Operative Reports (SAFE-OR) in general surgery.

Methods

SAFE-OR was developed by using consensus criteria set forth by the Canadian Association of General Surgeons. This instrument includes a structured assessment and a global quality rating scale. Residents divided into novice and experienced groups viewed and dictated a videotaped laparoscopic sigmoid colectomy. Blinded, independent faculty evaluators graded the transcribed reports using SAFE-OR.

Results

Twenty-one residents participated in the study. Mean structured assessment scores (out of 44) were significantly lower for novice versus experienced residents (23.3 ± 5.2 vs 34.1 ± 6.0, t = .001). Mean global quality scores (out of 45) were similarly lower for novice residents (25.6 ± 4.7 vs 35.9 ± 7.6, t = .006). Interclass correlation coefficients were .98 (95% confidence interval, .96–.99) for structured assessment and .93 (95% confidence interval, .83–.97) for global quality scales. Cronbach α coefficients for internal consistency were .85 for structured assessment and .96 for global quality assessment scales.

Conclusions

SAFE-OR shows significant construct validity, excellent interrater reliability, and high internal consistency. This tool will allow educators to objectively evaluate the quality of trainee operative reports and provide a mechanism for implementing, monitoring, and refining curriculum for dictation skills.

Study Objective

To develop a Structured Assessment Format for Evaluating Operative Reports (SAFE-OR) in gastrointestinal surgery and evaluate it for (1) interrater agreement, (2) construct validity, and (3) internal consistency.

Methods

SAFE-OR was developed by using the Canadian Association of General Surgeons consensus criteria for gastrointestinal operative procedures for both face and content validity [14]. It consists of a structured assessment form (Fig. 1) and a global quality ratings scale (Fig. 2).

Structured assessment items are of 2 types: simple, either correctly described or not (eg, “date of surgery”), or complex, with a spectrum of possible descriptions (eg, “technique of reconstruction”). Simple items are graded

Construct validity

The mean overall structured assessment score (out of 44) was significantly lower for novice versus experienced residents (23.3 ± 5.2 vs 34.1 ± 6.0, P = .001). The mean overall global quality score (out of 45) was also lower for novice versus experienced residents (25.6 ± 4.7 vs 35.9 ± 7.6, P = .006).

Reliability/internal consistency

The ICC for overall structured assessment scores was .98 (95% confidence interval, .96–.99). For ordinal elements, the ICC ranged from .73 to .90 (Table 1). For nominal structured assessment items,

Comments

“All clinical skills evaluations, regardless of purpose, structure, content or scoring, must be designed so that reliable and valid assessment scores and/or decisions can be made” [25]. Specifically, until now, no mechanism identified has been rigorously shown to measure what it purports to (validity) in a consistent and precise manner (reliability) when examining the quality of an operative report in general surgery.

      Participants were also asked to obtain six photographs at the beginning of each laparoscopic or robotic procedure corresponding to the six anatomical landmark zones of the pelvis. Cases were collected from the participating surgeons, de-identified, and independently scored by three judges, who also were all gynaecological surgeons, using the SAFE-OR.1 The photographs were printed and submitted to the study coordinator by depositing them into a locked box kept in each operating room.

      The quality of future care delivered may be hampered by poor communication [5]. Despite the clear importance of the operative report in the electronic medical record (EMR), few studies have addressed report quality [3,4,6–11]. Studies from other surgical specialties have shown standardized reports result in more complete and reliable interpretable operative data compared with non-standard operative reports [9].
