Background A pilot scheme to train NHS dental nurses across primary and secondary care settings was initiated by Health Education England (HEE) and delivered by local providers in London. This study explores stakeholders' views of the scheme in relation to structure, process and outcomes. Methods Sixteen semi-structured interviews were conducted with a purposive sample of stakeholders (education and training providers, representatives of HEE, a trainee) and one focus group discussion with trainees. Topic guides informed by literature and the initiative were used. Audio-recordings were transcribed and analysed using a framework approach. Results Structure: Support for the innovation in principle as it was perceived to deliver broad and complementary experience across primary and secondary care. It was also financially efficient over traditional hospital training. Structured communication between training partners and with trainees regarding finance and rotations would bolster the scheme. New Process established for the pilot delivered dual training but should be more explicit to stakeholders with recruitment to posts, practice placement allocations and on-site induction involving trainers at all sites. Informal mentoring which emerged was considered helpful and trainees would benefit from a structured mentoring programme. Outcome: Good examination success rates, support for the concept and an appreciation of the experience of working across environments and cultures. Overall, differences in workplace cultures and tensions were highlighted; these need to be given due consideration in future innovations. Conclusion The findings suggest that the value in cross-cultural training and learning from this innovation can be maximised by managing differences and expectations in future training schemes.
