Perioperative practice patterns of craniotomies - results of a national neurosurgical survey in Poland.

BACKGROUND Perioperative craniotomy practices depend mainly on neurosurgeon preferences. To investigate the variations in these preferences, we surveyed neurosurgeons in Poland regarding different aspects of their practices. METHODS Anonymous questionnaires were circulated in 2019 at the neurosurgery conferences in Poland. We then analyzed the responses, categorized in subgroups by sex, affiliation, and stage of training. RESULTS A total of 114 responses to the questionnaire were obtained. For surgical site exposure, regional hair shaving was the most common pattern (64.9%), followed by whole-scalp (19.3%) and strip line shaving (12.3%). Most respondents (65.8%) used clamp-based devices for bone flap fixation, and approximately one third (30.7%) reported using bone suturing. During cranioplasty, respondents most often used artificial bone implants (69.3%), followed by a preserved bone flap from the patient (24.5%). More than three quarters reported that they (77.2%) performed routine radiologic evaluation after uncomplicated brain tumor surgery. Most patients (64.0%) were discharged between the third and sixth postoperative days. Almost half of emergent surgeries (48.2%) and most elective surgeries (89.5%) were performed with the help of an assistant surgeon. No significant differences were found in practice between the sexes or by affiliation or training stage. We inferred an influence of regional economic status on some of the reported choices. CONCLUSIONS Perioperative craniotomy practices among Polish neurosurgeons show a significant heterogeneity. Economic factors can explain some choices, but others trace to a conservative mindset. Further studies are needed to identify which factors are most relevant and to identify approaches to a standardized method of care.
