Objective: The aim of this study was to gain insight in motivators and demotivators of the Dutch neurosurgical residents and neurosurgeons. Methods: A mixed method study was conducted. A survey was sent by the Dutch Neurosurgical Society to all Dutch neurosurgeons and residents in the framework of the yearly national quality conference. The focus groups were held during the Dutch national training days for neurosurgical residents. Baseline statistics were made of all survey data. Focus group recordings were transcribed verbatim and open coded in a constant comparative manner. Results: The survey yielded a response rate of 47.3% of neurosurgeons and 72.5% of residents. 42.5% of residents participated in the focus groups. Overall, motivators according to residents and neurosurgeons were divided between autonomous and controlled motivation. For residents, the motivators to become a neurosurgeon were mostly patient-centered. Neurosurgeons had the same general motivators as residents. Around one-third of neurosurgeons considered ending their career as a neurosurgeon. Among residents, 9.5% considered quitting residency. Neurosurgeons and residents indicated that no time for their family life, increased administrative burden and non-patient-related tasks were reasons to consider leaving the profession. Also, less perceived respect from patients and society was a reason to consider ending their career as a neurosurgeon. Conclusion: Neurosurgeons and residents in neurosurgery are mostly motivated by intrinsic motivators. Factors such as administrative burden, less perceived respect from patients and society, and increase in non-patient-related tasks are large demotivators for both neurosurgeons and residents.

Objective The aim of this study was to investigate the diagnostic accuracy of the pulsatility curve to predict shunt response in patients with idiopathic normal pressure hydrocephalus (iNPH). Methods Lumbar cerebrospinal fluid dynamics were derived from an automatic lumbar infusion test (LIT) protocol. All patients were treated with ventriculoperitoneal shunting and re-examined 6 months after shunting. Patient demographics and outcomes were gathered in a prospective, electronic database that spanned from January 2012 to January 2020. A validated iNPH scale was used to assess patients preoperatively and 6 months postoperatively. The relationship of the relative pulse pressure coefficient (RPPC), delta amplitude, successful lowering of amplitude, and the pressure-value at a hypothetical amplitude of zero (P0), resistance to outflow (Rout), and outcome, were assessed using receiver operating characteristic (ROC) curves. Results We included 38 patients. The RPPC, delta amplitude, successful lowering of amplitude, and P0 parameters did not predict shunt response. Mean P0 was 0.5 (IQR 0.4–0.9) in improved patients and 0.4 (IQR 0–1.2) in non-improved patients. The delta amplitude was 0.16 kPa (IQR 0.10–0.23) in improved patients and 0.18 kPa (IQR 0.11–0.24) in non-improved patients. Furthermore, we found a technical failure rate of pulsatility curve measurements of 32%. Conclusion Pulsatility curve results were not suitable in predicting shunt response in our cohort. The diagnostic value of LIT in case of normal pressure hydrocephalus should be subject to more rigorous research.
