Use of a quality improvement strategy to introduce co-design of the mental health discharge plan in rural and remote New South Wales.

PROBLEM: Patients have not traditionally partnered in the design of their discharge plans, with discharge summaries at times not completed. In rural settings, discharge planning communicates care to a complex geographic area with fragmented resources. Patients may also be socially disadvantaged, with relatives and friends sometimes excluded. DESIGN: Situational analysis and liaison with key partners occurred in the months prior to the core project. Opportunities for improvement were noted. An audit of all discharges in May 2020 was planned to assess rates of discharge completion, co-design and inclusion of next of kin. Qualitative feedback was also noted from staff. SETTING: Dubbo inpatient mental health units (Gundaymarra and Barraminya). KEY MEASURES FOR IMPROVEMENT: Rates of discharge summary completion, co-design of discharge plan, engagement of next of kin. Qualitative measures included reflections of clinical staff involved. STRATEGY FOR CHANGE: Junior doctors were key in facilitating each patient to co-design their discharge plan and collaborate with all biological and psychosocial treatments and providers in a forum for open discussion. The inclusion of nominated next of kin was core. EFFECTS OF CHANGE: Discharge summary completion rates were high; co-design of discharge plans occurred frequently; and next of kin were involved with few exceptions. The adoption of the person as expert in modifying their plan became a norm. Medical staff wanted this care frame for each person. LESSONS LEARNT: Engaging patients and their next of kin directly in their discharge planning improves care opportunities in a rural setting, as well as understanding for all parties. This approach also prioritises the process of discharge completion.

Metabolic screen and intervene: improving mental health inpatient metabolic monitoring.

OBJECTIVE: To assess rates of metabolic monitoring in patients prescribed antipsychotic medications in the psychiatric inpatient setting and the impact education can have regarding monitoring compliance. METHOD: Two identical audits were undertaken at a NSW mental health inpatient service before and after a campaign designed to educate mental health workers about the importance of metabolic monitoring. Results from both audits were compared for statistically significant improvements in monitoring rates. RESULTS: Rates of monitoring plasma lipids increased from 21.7% to 78.8% (p < 0.01) and rates for plasma glucose increased from 20.8% to 73.7% (p < 0.01). There were no statistically significant changes in rates of monitoring body mass index (83.0% and 77.1%, respectively), waist circumference (36.8% and 43.2%, respectively) and blood pressure (99.1% and 100%, respectively). CONCLUSION: This study has shown that rates of metabolic monitoring in the inpatient setting can be improved with a relatively low-cost education intervention. While absolute rates remain low, outcomes suggest that it may be worthwhile trialling further modes of education and repeating this education in cycles.

The Role of Sacral Slope in the Progression of a Bilateral Spondylolytic Defect at L5 to Spondylolisthesis: A Biomechanical Investigation Using Finite Element Analysis.

STUDY DESIGN: A biomechanical study using finite element analysis. OBJECTIVES: The main objective of this study was to investigate the role of sacral slope in the progression of a L5 bilateral spondylolytic defect to spondylolisthesis. METHODS: A 3-dimensional model of lumbosacral spine was built using computed tomography (CT) data procured from an anonymized healthy male subject. The segmented CT data was manipulated to generate 3 more models representing L5 bilateral spondylolytic defect with normal sacral slope (SS), sacral slope increased by 10° (SS+10), and sacral slope decreased by 10° (SS-10). The 3D models were imported into finite element modelling software Strand7 for preprocessing, running nonlinear static solves, and postprocessing of the results. RESULTS: Directional biomechanical instabilities were induced in the lumbosacral spine as a result of changes in the L5-S1 disc shape secondary to the changes in sacral slope. Compared with the normal L5 lytic model, wedging of the L5-S1 disc (SS+10) resulted in a significantly greater range of motion in flexion (18% ↑) but extension motion characteristics were similar. Conversely, flattening of the L5-S1 disc (SS-10) resulted in a significantly greater range of motion in extension (16% ↑) but flexion motion characteristics were similar to that of the normal L5 lytic model. CONCLUSIONS: Variations in sacral slope while preserving the L5-S1 mid-disc height and orientation of the L5 vertebra resulted in variations in the L5-S1 disc shape. The results suggest that for such extremities in the L5-S1 disc shape different pathomechanisms exist for the progression of the L5 lytic defect to spondylolisthesis.

Mild (not severe) disc degeneration is implicated in the progression of bilateral L5 spondylolysis to spondylolisthesis.

BACKGROUND: Spondylolytic (or lytic) spondylolisthesis is often associated with disc degeneration at the index-level; however, it is not clear if disc degeneration is the cause or the consequence of lytic spondylolisthesis. The main objective of this computed tomography based finite element modelling study was to examine the role of different grades of disc degeneration in the progression of a bilateral L5-lytic defect to spondylolisthesis. METHODS: High-resolution computed tomography data of the lumbosacral spine from an anonymised healthy male subject (26 years old) were segmented to build a 3D-computational model of an INTACT L1-S1 spine. The INTACT model was manipulated to generate four more models representing a bilateral L5-lytic defect and the following states of the L5-S1 disc: nil degeneration (NOR LYTIC), mild degeneration (M-DEG LYTIC), mild degeneration with 50% disc height collapse (M-DEG-COL LYTIC), and severe degeneration with 50% disc height collapse(S-COL LYTIC). The models were imported into a finite element modelling software for pre-processing, running nonlinear-static solves, and post-processing of the results. RESULTS: Compared with the baseline INTACT model, M-DEG LYTIC model experienced the greatest increase in kinematics (Fx range of motion: 73% ↑, Fx intervertebral translation: 53%↑), shear stresses in the annulus (Fx anteroposterior: 163%↑, Fx posteroanterior: 31%↑), and strain in the iliolumbar ligament (Fx: 90%↑). The S-COL LYTIC model experienced a decrease in mobility (Fx range of motion: 48%↓, Fx intervertebral translation: 69%↓) and an increase in normal stresses in the annulus (Fx Tensile: 170%↑; Fx Compressive: 397%↑). No significant difference in results was noted between M-DEG-COL LYTIC and S-COL LYTIC models. CONCLUSIONS: In the presence of a bilateral L5 spondylolytic defect, a mildly degenerate index-level disc experienced greater intervertebral motions and shear stresses compared with a severely degenerate index-level disc in flexion and extension bending motions. Disc height collapse, with or without degenerative changes in the stiffness properties of the disc, is one of the plausible re-stabilisation mechanisms available to the L5-S1 motion segment to mitigate increased intervertebral motions and shear stresses due to a bilateral L5 lytic defect.

Is Stand-Alone Anterior Lumbar Interbody Fusion a Safe and Efficacious Treatment for Isthmic Spondylolisthesis of L5-S1?

STUDY DESIGN: A systematic review. OBJECTIVE: The objective of this study was to determine the safety and efficacy of stand-alone anterior lumbar interbody fusion (sa-ALIF) for the treatment of symptomatic isthmic spondylolisthesis of L5-S1 by assessing the level of available clinical and radiographic evidence. METHODS: A systematic review utilizing Medline, Embase, and Scopus online databases was undertaken. Clinical, radiographic, and adverse outcome data were extracted for the relevant isthmic spondylolisthesis cases with the intention of undertaking a meta-analysis. RESULTS: The database search between January 1980 and December 2015 yielded 23 articles that concerned sa-ALIF for isthmic spondylolisthesis of L5-S1. Only in 9 of the 23 articles data could be extracted specific to sa-ALIF for isthmic spondylolisthesis of L5-S1. There was considerable inconsistency in the standards for reporting outcomes of the surgery due to which meta-analysis could not be undertaken, and hence each article was reviewed. CONCLUSIONS: There was insufficient evidence to support the safety and efficacy of sa-ALIF for the treatment of isthmic spondylolisthesis of L5-S1. Although sa-ALIF is widely documented in the literature, there was insufficient evidence to support its use in treating this specific pathology. The unique pathological and anatomical situation that isthmic spondylolisthesis of L5-S1 presents must be recognized and its treatment with sa-ALIF should be well thought out.
