Guideline-concordant utilization of magnetic resonance imaging in adults receiving chiropractic manipulative therapy vs other care for radicular low back pain: a retrospective cohort study

BACKGROUND

Lumbar magnetic resonance imaging (LMRI) is often performed early in the course of care, which can be discordant with guidelines for non-serious low back pain. Our primary hypothesis was that adults receiving chiropractic spinal manipulative therapy (CSMT) for incident radicular low back pain (rLBP) would have reduced odds of early LMRI over 6-weeks' follow-up compared to those receiving other care (a range of medical care, excluding CSMT). As a secondary hypothesis, CSMT recipients were also expected to have reduced odds of LMRI over 6-months' and 1-years' follow-up.

METHODS

A national 84-million-patient health records database including large academic healthcare organizations (TriNetX) was queried for adults age 20-70 with rLBP newly-diagnosed between January 31, 2012 and January 31, 2022. Receipt or non-receipt of CSMT determined cohort allocation. Patients with prior lumbar imaging and serious pathology within 90 days of diagnosis were excluded. Propensity score matching controlled for variables associated with LMRI utilization (e.g., demographics). Odds ratios (ORs) of LMRI over 6-weeks', 6-months', and 1-years' follow-up after rLBP diagnosis were calculated.

RESULTS

After matching, there were 12,353 patients per cohort (mean age 50 years, 56% female), with a small but statistically significant reduction in odds of early LMRI in the CSMT compared to other care cohort over 6-weeks' follow-up (9%, 10%, OR [95% CI] 0.88 [0.81-0.96] P = 0.0046). There was a small but statistically significant increase in odds of LMRI among patients in the CSMT relative to the other care cohort over 6-months' (12%, 11%, OR [95% CI] 1.10 [1.02-1.19], P < 0.0174) and 1-years' follow-up (14%, 12%, OR [95% CI] 1.21 [1.13-1.31], P < 0.0001).

CONCLUSIONS

These results suggest that patients receiving CSMT for newly-diagnosed rLBP are less likely to receive early LMRI than patients receiving other care. However, CSMT recipients have a small increase in odds of LMRI over the long-term. Both cohorts in this study had a relatively low rate of early LMRI, possibly because the data were derived from academic healthcare organizations. The relationship of these findings to other patient care outcomes and cost should be explored in a future randomized controlled trial.

Defining Pooled' Place-Based' Budgets for Health and Social Care: A Scoping Review

Introduction

Current descriptions of pooled budgets in the literature pose challenges to good quality evaluation of their contribution to integrated care. Addressing this gap is increasingly important given the shift from early models of integrated care targeting segments of the population, to more recent approaches that aim to target 'places', broader geographically defined populations. This review draws on the current international evidence to describe practical examples of pooled health and social care budgets, highlighting specific place-based approaches.

Methods

We initially conducted a scoping review, a systematic database search ('Medline', 'Embase', 'Econ Lit' and 'Google Scholar') complemented by further snowballing for academic and 'grey literature' publications (1995 - 2020). Results were analysed thematically according to budget characteristics and macro-environment, with additional specific case studies.

Results

Thirty-six primary studies were included, describing ten broad models of pooled budgets across seven countries. Most budgets targeted specific sub-populations rather than an entire geographically defined population. Specific budget structures varied and were generally under-described. The closest place-based models were for small populations and implemented in a national health system, or insurance-based with natural geographical boundaries.

Conclusion

Despite their increasing relevance in the current political debate, pooled place-based budgets are still at an early stage of implementation and research. Adequate description is required for future meta-analysis of effectiveness on outcomes.

The Baltimore Community-Based Organizations Neighborhood Network: Enhancing Capacity Together (CONNECT) Cluster RCT

INTRODUCTION

This cluster RCT aimed to reduce healthcare utilization and increase the referral of patients between an academic health center and local community-based organizations (CBOs) that address social determinants of health.

STUDY DESIGN

Cluster RCT.

SETTINGS/PARTICIPANTS

Twenty-two CBOs located in Baltimore, Maryland, were randomly assigned to the intervention or control group, and 5,255 patients were allocated to the intervention or control group based on whether they lived closer to an intervention or control CBO. Data were collected in 2014-2016; the analysis was conducted in 2016.

INTERVENTION

A multicomponent intervention included an online tool to help refer clients to community resources, meet-and-greet sessions between CBO staff and healthcare staff, and research assistants.

MAIN OUTCOME MEASURES

The primary outcomes were patient emergency department visits and days spent in the hospital. Additional outcomes for CBO clients included knowledge of other CBOs, number of referrals to CBOs by the healthcare system, and number of referrals to healthcare system by CBOs. Outcomes for CBO staff included the number of referrals made to and received from the healthcare system and the number of referrals made to and received from other CBOs.

RESULTS

There was no significant effect of the intervention on healthcare utilization outcomes, CBO client outcomes, or CBO staff outcomes. Ancillary analyses demonstrated a 2.9% increase in referrals by inpatient staff to intervention CBOs (p=0.051) and a 6.6% increase in referrals by outpatient staff to intervention CBOs between baseline and follow-up (p=0.027). Outpatient staff reported a significant reduction in barriers related to the lack of information about CBO services (-18.3%, p=0.004) and an increase in confidence in community resources (+14.4%, p=0.023) from baseline to follow-up.

CONCLUSIONS

The intervention did not improve healthcare utilization outcomes but was associated with increased healthcare staff knowledge of, and confidence in, local CBOs.
