Closing the gap on healthcare quality for equity-deserving groups: a scoping review of equity-focused quality improvement interventions in medicine.

INTRODUCTION: Quality improvement (QI) efforts are critical to promoting health equity and mitigating disparities in healthcare outcomes. Equity-focused QI (EF-QI) interventions address the unique needs of equity-deserving groups and the root causes of disparities. This scoping review aims to identify themes from EF-QI interventions that improve the health of equity-deserving groups, to serve as a resource for researchers embarking on QI. METHODS: In adherence with Preferred Reporting Items for Systematic Reviews and Meta-analysis guidelines, several healthcare and medical databases were systematically searched from inception to December 2022. Primary studies that report results from EF-QI interventions in healthcare were included. Reviewers conducted screening and data extraction using Covidence. Inductive thematic analysis using NVivo identified key barriers to inform future EF-QI interventions. RESULTS: Of 5,330 titles and abstracts screened, 36 articles were eligible for inclusion. They reported on EF-QI interventions across eight medical disciplines: primary care, obstetrics, psychiatry, paediatrics, oncology, cardiology, neurology and respirology. The most common focus was racialised communities (15/36; 42%). Barriers to EF-QI interventions included those at the provider level (training and supervision, time constraints) and institution level (funding and partnerships, infrastructure). The last theme critical to EF-QI interventions is sustainability. Only six (17%) interventions actively involved patient partners. DISCUSSION: EF-QI interventions can be an effective tool for promoting health equity, but face numerous barriers to success. It is unclear whether the demonstrated barriers are intrinsic to the equity focus of the projects or can be generalised to all QI work. Researchers embarking on EF-QI work should engage patients, in addition to hospital and clinic leadership in the design process to secure funding and institutional support, improving sustainability. To the best of our knowledge, no review has synthesised the results of EF-QI interventions in healthcare. Further studies of EF-QI champions are required to better understand the barriers and how to overcome them.

Systems-Based Practice in Graduate Medical Education: Evolving Toward an Ideal Future State.

ABSTRACT: Systems-based practice (SBP) was first introduced as a core competency in graduate medical education (GME) in 2002 by the Accreditation Council for Graduate Medical Education as part of the Outcomes Project. While inclusion of SBP content in GME has become increasingly common, there have also been well-documented stumbling blocks, including perceptions that SBP has eroded the amount of curricular time available for more medically focused competencies, is not relevant for some practice contexts, and is not introduced early enough in training. As a result, SBP learning experiences often feel disconnected from medical trainees' practical reality. In this commentary, the authors provide guidance regarding potential changes that may facilitate the evolution of SBP toward an ideal future state where graduates bring a systems science mindset to all aspects of their work. Specific suggestions include the following: (1) expanding the SBP toolbox to reflect current-day health system needs, (2) evolve the teaching methodology, (3) broadening the scope of relevant SBP content areas, and (4) emphasizing SBP as an integrated responsibility for all health care team members. Levers to enact this transformation exist and must be used to influence change at the learner, faculty, program, and clinical learning environment levels.Physicians operate within an increasingly complex health care system that highlights the intersection of health care with complex social, environmental, and relational contexts. Consequently, the role of SBP in both physician work responsibilities and educational requirements continues to expand. To meet this growing demand, GME must adapt how it supports and trains the next generation of systems thinkers, ensuring they understand how levers in the health care system directly affect health outcomes for their patients, and integrate SBP into the foundation of GME curricula in an inclusive, holistic, and unrestrained way.

Using the relationship between brain tissue regional saturation of oxygen and mean arterial pressure to determine the optimal mean arterial pressure in patients following cardiac arrest: A pilot proof-of-concept study.

INTRODUCTION: Prospectively assess cerebral autoregulation and optimal mean arterial pressure (MAPOPT) using the dynamic relationship between MAP and regional saturation of oxygen (rSO2) using near-infrared spectroscopy. METHODS: Feasibility study of twenty patients admitted to the intensive care unit following a cardiac arrest. All patients underwent continuous rSO2 monitoring using the INVOS(®) cerebral oximeter. ICM+(®) brain monitoring software calculates the cerebral oximetry index (COx) in real-time which is a moving Pearson correlation coefficient between 30 consecutive, 10-s averaged values of MAP and correspond rSO2 signals. When rSO2 increases with increasing MAP (COx ≥0.3), cerebral autoregulation is dysfunctional. Conversely, when rSO2 remains constant or decreases with increasing MAP (COx <0.3), autoregulation is preserved. ICM+(®) fits a U-shaped curve through the COx values plotted vs. MAP. The MAPOPT is nadir of this curve. RESULTS: The median age was 59 years (IQR 54-67) and 7 of 20 were female. The cardiac arrest was caused by myocardial infarction in 12 (60%) patients. Nineteen arrests were witnessed and return of spontaneous circulation occurred in a median of 15.5min (IQR 8-33). Patients underwent a median of 30h (IQR 23-46) of monitoring. COx curves and MAPOPT were generated in all patients. The mean overall MAP and MAPOPT were 76mmHg (SD 10) and 76mmHg (SD 7), respectively. MAP was outside of 5mmHg from MAPOPT in 50% (SD 15) of the time. Out of the 7672 5-min averaged COx measurements, 1182 (15%) were at 0.3 or above, indicating absence of autoregulation. Multivariable polynomial fractional regression demonstrated an increase in COx with increasing temperature (P=0.008). CONCLUSIONS: We demonstrated the feasibility to determine a MAPOPT using cerebral oximetry in patients after cardiac arrest.

Missed Opportunities for HIV Prophylaxis Among Emergency Department Patients With Occupational and Nonoccupational Body Fluid Exposures.

STUDY OBJECTIVE: Exposures to HIV are frequently managed in the emergency department (ED) for assessment and potential initiation of HIV postexposure prophylaxis. Despite established guidelines, it is unclear whether patients with a nonoccupational exposure are managed similarly to patients with an occupational exposure. METHODS: This retrospective study used an administrative database to identify consecutive patients at a single ED with a discharge diagnosis of "blood or body fluid exposure" without sexual assault from April 1, 2007 to June 30, 2013. Patient exposure details and physician management were ascertained according to predefined guidelines. The primary outcome was the proportion of patients with high-risk exposures who were correctly given HIV prophylaxis; the secondary outcome was the proportion of patients with low-risk exposures who were correctly not given HIV prophylaxis. Other outcomes included the proportion of patients who had a baseline HIV test in the ED, the proportion who followed up with an HIV test within 6 months, and the number of seroconversions in this group. All outcomes were compared between nonoccupational and occupational exposure. RESULTS: Of 1,972 encounters, 1,358 patients (68.9%) had an occupational exposure and 614 (31.1%) had a nonoccupational exposure. In the occupational exposure group, 190 patients (14.0%) were deemed high risk, with 160 (84.2%; 95% confidence interval [CI] 78.1% to 88.9%) appropriately given prophylaxis. In the nonoccupational exposure group, 287 patients (46.7%) had a high-risk exposure, with 208 (72.5%; 95% CI 66.8% to 77.5%) given prophylaxis, for a difference of 11.7% (95% CI 3.8% to 19.1%). For low-risk exposures, appropriate management of both occupational and nonoccupational exposure was similar (92.4% versus 93.0%). At the index ED visit, 90.5% of occupational exposure patients and 76.7% of nonoccupational exposure patients received HIV testing, for a difference of 13.8% (95% CI 10.1% to 17.7%). At 6 months, 25.4% of patients with an occupational exposure and 35.0% of patients with a nonoccupational exposure had a follow-up test, for a difference of -9.6% (95% CI -14.2% to -5.1%). Of patients who had follow-up testing within 6 months, 4 of 215 (1.9%) in the nonoccupational exposure group tested newly positive for HIV, whereas 0 of 345 (0%) in the occupational exposure group tested positive. CONCLUSION: For ED patients with blood or body fluid exposures, those with high-risk nonoccupational exposures were not given HIV prophylaxis nearly twice as often as those with high-risk occupational exposure. Although 6-month follow-up testing rates were low, 1.9% of high-risk nonoccupational exposure patients seroconverted.

Association between blood pressure and outcomes in patients after cardiac arrest: A systematic review.

OBJECTIVE: Hypoxic ischaemic brain injury (HIBI) is a major cause of disability after cardiac arrest. HIBI leads to impaired cerebral autoregulation such that adequate cerebral perfusion becomes critically dependent on blood pressure. However, the optimal blood pressure after cardiac arrest remains unclear. Therefore, we conducted a systematic review to investigate the association between blood pressure and neurologic outcome patients after cardiac arrest. METHODS: We systematically searched MEDLINE, EMBASE, conference abstracts and article references to identify randomized and observational studies investigating the relationship between blood pressure and neurologic outcome. We included studies that reported adjusted point estimates for the relationship between blood pressure and neurologic status in adult patients after cardiac arrest. RESULTS: We included 9 studies with a total of 13,150 patients. Three studies included only patients with an out-of-hospital cardiac arrest. There was marked between-study heterogeneity with respect to blood pressure definition (MAP vs. systolic), exposure duration and modelling (dichotomous vs. continuous). All studies examined either mortality or neurological status as an outcome. Seven of nine studies demonstrated that higher blood pressure was associated with improved outcomes either by an association between higher MAP and good neurologic outcome or the presence of hypotension and increased odds of mortality. CONCLUSIONS: The included studies suggest improved neurologic outcomes are associated with higher blood pressures in patients after cardiac arrest. This study highlights a need for further research to define the optimal management of blood pressure in this population.

Building a Generation of Physician Advocates: The Case for Including Mandatory Training in Advocacy in Canadian Medical School Curricula.

There is an increasing focus on the social accountability of physicians as individuals, and of medicine itself. This has led to increasing emphasis on physician advocacy from a wide variety of institutions. The physician advocacy concept is now part of the Health Advocacy competency mandated by the Royal College of Physicians and Surgeons of Canada. Despite its growing prominence, physician advocacy remains poorly integrated into current medical undergraduate curricula. The authors recommend how and why curricular reform should proceed; they focus on Canadian medical education, although they hope their views will be useful in other countries as well.The authors discuss conflicting definitions of physician advocacy, which have previously hampered curriculum development efforts, and suggest a way of reconciling the conflicts. They review current gaps in advocacy-related curricula, suggest that these can be addressed by incorporating practice-based and skills acquisition elements into current didactic teaching, and offer several strategies by which an advocacy curriculum could be implemented, ranging from small modifications to current curriculum to developing new competencies in medical education nationally.The authors present a case for making an advocacy curriculum mandatory for every Canadian medical trainee; they argue that teaching trainees how to fulfill their professional responsibility to advocate may also help them meet the social accountability mandate of medical school education. Finally, the authors explain why making the development and implementation of a mandatory, skill-based curriculum in advocacy should be a priority.
