Regarding Mahmud et al., 2021, Benchmarking services in outpatient hysteroscopy (OPH): A quality improvement project-Letter to the Editor.

We read Mahmud and colleagues’ [ [1] ] recent publication regarding outpatient hysteroscopy (OPH) with great interest. Having recently published our own OPH study [ [2] ], the similarity of the findings was striking. Specifically, average pain rating on an 11-point numerical rating scale (NRS) were rated 3.97 (sd = 2.45) in our study and 5.2 (sd = 2.73) in Mahmud et al.’s, with respective similarities in proportion of pain-free patients (7.8% vs 9%).
