Lessons from observational and retrospective studies

Both a retrospective analysis and an observational report looked at data collected from a free New Zealand outpatient clinic affiliated with a hospital (9, 10). Although neither of these reports were RCTs, they add value to the conversation because they demonstrate successful integrative partnership between an allopathic medical model and an alternative one. Pregnant patients were largely referred to the acupuncture clinic by midwives acting as lead maternity caregivers (LMC). This partnership has existed since 2013 and is ongoing, reflecting the collaborative relationship and positive feedback from patients over the years that allowed this model to continue. Upon self-assessment, the women reported clinically meaningful reduction in LBP and PP, and reported that any adverse events were minor and not significant enough to override the positive effects they experienced from acupuncture treatments.
