Theory-based implementation of an enhanced recovery protocol for cranial surgery

Abstract

OBJECTIVE There is growing evidence for the use of enhanced recovery protocols (ERPs) in cranial surgery. As they become widespread, successful implementation of these complex interventions will become a challenge for neurosurgical teams owing to the need for multidisciplinary engagement. Here, the authors describe the novel use of an implementation framework (normalization process theory [NPT]) to promote the incorporation of a cranial surgery ERP into routine neuro-oncology practice. METHODS A baseline audit was conducted to determine the degree of implementation of the ERP into practice. The Normalization MeAsure Development (NoMAD) questionnaire was circulated among 6 groups of stakeholders (neurosurgeons, anesthetists, intensivists, recovery nurses, preoperative assessment nurses, and neurosurgery ward staff) to examine barriers to implementation. Based on these findings, a theory-guided implementation intervention was delivered. A repeat audit and NoMAD questionnaire were conducted to assess the impact of the intervention on the uptake of the ERP. RESULTS The baseline audit (n = 24) demonstrated limited delivery of the ERP elements. The NoMAD questionnaire (n = 32) identified 4 subconstructs of the NPT as barriers to implementation: communal specification, contextual integration, skill set workability, and relational integration. These guided an implementation intervention that included the following: 1) teamwork-focused training; 2) ERP promotion; and 3) procedure simplification. The reaudit (n = 21) demonstrated significant increases in the delivery of 5 protocol elements: scalp block (12.5% of patients before intervention vs 76.2% of patients after intervention, p < 0.00001), recommended analgesia (25.0% vs 100.0%, p < 0.00001) and antiemetics (12.5% vs 100.0%, p < 0.00001), trial without catheter (13.6% vs 88.9%, p < 0.00001), and mobilization on the 1st postoperative day (45.5% vs 94.4%, p < 0.00001). There was a significant reduction in the mean hospital length of stay from 6.3 ± 3.4 to 4.2 ± 1.7 days (p = 0.022). Two months after implementation, a repeat NoMAD survey demonstrated significant improvement in communal specification. CONCLUSIONS Here, the authors have demonstrated the successful implementation of a cranial surgery ERP by using a systematic theory-based approach.
