International comparative study of low back pain care pathways and analysis of key interventions.

PURPOSE: Low back pain (LBP) is a major public health problem worldwide. Significant practice variation exists despite guidelines, including strong interventionist focus by some practitioners. Translation of guidelines into pathways as integrated treatment plans is a next step to improve implementation. The goal of the present study was to analyze international examples of LBP pathways in order to identify key interventions as building elements for care pathway for LBP and radicular pain. METHODS: International examples of LBP pathways were searched in literature and grey literature. Authors of pathways were invited to fill a questionnaire and to participate in an in-depth telephone interview. Pathways were quantitatively and qualitatively analyzed, to enable the identification of key interventions to serve as pathway building elements. RESULTS: Eleven international LBP care pathways were identified. Regional pathways were strongly organized and included significant training efforts for primary care providers and an intermediate level of caregivers in between general practitioners and hospital specialists. Hospital pathways had a focus on multidisciplinary collaboration and stepwise approach trajectories. Key elements common to all pathways included the consecutive screening for red flags, radicular pain and psychosocial risk factors, the emphasis on patient empowerment and self-management, the development of evidence-based consultable protocols, the focus on a multidisciplinary work mode and the monitoring of patient-reported outcome measures. CONCLUSION: Essential building elements for the construction of LBP care pathways were identified from a transversal analysis of key interventions in a study of 11 international examples of LBP pathways.

Use of hyperglycemic clamp to assess pancreatectomy and islet cell autotransplant in patient with heterotaxy syndrome and dorsal pancreas agenesis leading to chronic pancreatitis.

Patients with heterotaxy syndrome (HS) can present with an associated complete dorsal pancreas agenesis (DPA). They are considered to be at increased risk for developing diabetes due to a reduced functional beta cell mass (FBM) as well as for chronic pancreatitis leading to unmanageable pain. We report the case of a young woman with chronic pancreatitis due to HS and associated DPA. She presented with a severe persisting upper abdominal pain refractory to nonsurgical treatment. Unlike in previously reported cases, she had a high FBM (ie, 150% of normoglycemic controls) as determined by hyperglycemic clamp. She underwent a total pancreatectomy followed within 24 hours by an intraportal autologous islet cell transplant containing 4 × 106 beta cells (4700 islet equivalent)/kg body weight. After surgery, the pain resolved, eliminating the need for analgesics. The intraportal implant established an adequate FBM (72% of controls at posttransplant month 2), achieving glycemic control without need for insulin administration. A hyperglycemic clamp can assess the utility and efficacy of an intraportal islet cell autotransplant following total pancreatectomy in patients with HS and complete DPA.
