Variation in Risk-Adjusted Ventilator-Associated Pneumonia Days Within a Quality Collaborative

IntroductionVentilator-associated pneumonia (VAP) is associated with increased mortality, prolonged mechanical ventilation, and longer intensive care unit stays. The rate of VAP (VAPs per 1000 ventilator days) within a hospital is an important quality metric. Despite adoption of preventative strategies, rates of VAP in injured patients remain high in trauma centers. Here, we report variation in risk-adjusted VAP rates within a statewide quality collaborative. MethodsUsing Michigan Trauma Quality Improvement Program data from 35 American College of Surgeons–verified Level I and Level II trauma centers between November 1, 2020 and January 31, 2023, a patient-level Poisson model was created to evaluate the risk-adjusted rate of VAP across institutions given the number of ventilator days, adjusting for injury severity, physiologic parameters, and comorbid conditions. Patient-level model results were summed to create center-level estimates. We performed observed-to-expected adjustments to calculate each center's risk-adjusted VAP days and flagged outliers as hospitals whose confidence intervals lay above or below the overall mean. ResultsWe identified 538 VAP occurrences among a total of 33,038 ventilator days within the collaborative, with an overall mean of 16.3 VAPs per 1000 ventilator days. We found wide variation in risk-adjusted rates of VAP, ranging from 0 (0-8.9) to 33.0 (14.4-65.1) VAPs per 1000 d. Several hospitals were identified as high or low outliers. ConclusionsThere exists significant variation in the rate of VAP among trauma centers. Investigation of practices and factors influencing the differences between low and high outlier institutions may yield information to reduce variation and improve outcomes.

The Effect of COVID-19 on Rib Fracture Patients in Michigan.

This study aims to compare outcomes of rib fracture patients with and without COVID-19 in Michigan. Data from the Michigan Trauma Quality Improvement Program (MTQIP) identified adults hospitalized from January 1, 2020, to October 31, 2022, with at least one rib fracture and a completed COVID-19 test on admission. Patients were propensity score matched 1:1 using 20 variables. The primary outcome was hospital length of stay (LOS). Secondary outcomes were mortality, ventilator days, intensive care unit (ICU) LOS, pneumonia, and ventilator-assisted pneumonia (VAP). 13,305 total patients were identified. 232 patients matched into both the COVID+ and COVID- groups. COVID was associated with increased LOS (7days vs. 5days, P < 0.001). There were no significant differences between the two groups when evaluating secondary outcomes. Our study indicates that although COVID-19 infection is associated with increased LOS, COVID may not contribute to additional morbidity or mortality in traumatic rib fracture patients.

A Geospatial Analysis of Hand Trauma Care: A Statewide Cross-Sectional Study.

Traumatic hand injuries often present with high acuity, but little is known about the influence of geospatial and socioeconomic factors on the timely delivery of care. This cross-sectional study used the Michigan Trauma Quality Improvement Program database, a state-wide registry with 35 level I or II trauma centers. Adult patients sustained hand trauma requiring urgent operative treatment between 2016 and 2021. Zip codes of injury location were linked with the corresponding percentile score on the Area Deprivation Index (ADI), a comprehensive measure of neighborhood disadvantage. Multiple regression analyses were used to determine associations of patient, injury and geospatial characteristics with the odds of sustaining acute hand trauma and time to operative treatment. Among 1,826 patients, the odds of sustaining acute hand trauma based on the ADI followed a bimodal distribution. Female sex, smoking, obesity, work-related injury and residence in a minor city were associated with increased odds, while younger age, comorbidities, and rural residence were associated with decreased odds. For 388 patients who underwent surgery within 48 hours, time to treatment was significantly increased in the highest ADI quintile, for patients who underwent fracture fixation, and for those with severe global injury severity. Multi-system injuries, moderate global injury severity and direct admission to an orthopaedic service were associated with shorter times to treatment. Patients in areas with greater neighborhood disadvantage may experience delayed operative care after acute hand trauma. This study highlights the importance of considering underserved populations and geospatial factors when determining the allocation of hand surgery resources. Prognostic Level III.

Outcomes of simultaneous versus staged intramedullary nailing fixation of multiple long bone lower extremity fractures

IntroductionRepair of multiple lower extremity long bone fractures with intramedullary nail (IMN) fixation is associated with significant cardiopulmonary burden and may result in mortality. These patients are at an increased risk for fat embolism syndrome, pulmonary embolism, Acute Respiratory Distress Syndrome (ARDS), and pneumonia. No standardized guidelines exist to guide treatment of these patients. Further, there is a paucity of data regarding the risk of simultaneous versus staged fixation of multiple long bone fractures that includes both tibial and femoral injuries, as patients with multiple concomitant fractures are often excluded from relevant analyses. Our level one trauma center aimed to identify whether simultaneous fixation, defined by definitive fixation of multiple lower extremity long bone fractures during one operative event, led to increased cardiopulmonary complications as compared to a staged approach, defined as multiple operations to reach definitive fixation. Patients and methodsThe Michigan Trauma Quality Improvement Program (MTQIP) database from 35 Level I and II trauma centers was queried to identify patients from January 2016 - December 2019. The primary outcome was incidence of cardiopulmonary complications for staged and simultaneous IMN fixation. ResultsWe identified 11,427 patients with tibial and/or femoral fractures during the study period. 146 patients met the inclusion criteria of two or more fractures treated with IMN fixation. 118 patients underwent simultaneous IMN fixation, and 28 patients received staged IMN fixation. There were no significant differences in injury severity score (ISS), demographics, pre-existing conditions, and cardiopulmonary complications between the two groups. There was a statistically significant difference in hospital length of stay (LOS) (p = 0.0012). The median hospital LOS for simultaneous fixation was 8.3 days versus 15.8 days for the staged cohort, a difference of 7.5 days. ConclusionThis is the largest retrospective study to date examining simultaneous versus staged IMN fixation in patients with multiple long bone lower extremity fractures. In contrast to previous studies, we found no difference in cardiopulmonary complications. Given these findings, patients with multiple long bone lower extremity fractures should be considered for simultaneous IMN, an approach which may decrease hospital LOS.

Effect of Antiplatelet and Anticoagulant Agents on Outcomes Following Emergent Surgery for Traumatic Brain Injuries.

Traumatic brain injury (TBI) is the largest cause of death from injury in the United States. This study utilized the Michigan Trauma Quality Improvement Program (MTQIP) database to determine the effect that antiplatelets and anticoagulants (AP/AC) have on outcomes following emergent surgery for TBI patients. Patients were included with age ≥18years, maximum head/neck abbreviated injury score (AIS) ≥2, and underwent a neurosurgical procedure within 24hours. Patients were excluded if they had an AIS ≥3 in other body region or no signs of life at initial evaluation. Within the 1,932 patients analyzed, 139 (8.74%) were in the warfarin with or without (+/-) aspirin cohort, 101 (6.35%) in the direct oral anticoagulants (DOAC) +/- aspirin cohort, 169 (10.62%) in the clopidogrel +/- aspirin cohort, and 1,182 (74.29%) in the no AP/AC cohort (control group). After controlling for demographic and clinical characteristics, no significant difference in mortality rates was observed in the treatment groups (P > 0.05). However, our subgroup analysis did reveal a significantly higher mortality rate within the warfarin and aspirin subgroup when compared to the control group (odds ratio [OR], 2.368; confidence interval [CI], 1.306-4.294, P = 0.005). With regards to hospital complications, there was a significant increase in this outcome within the DOAC +/- aspirin (OR, 1.825; CI, 1.143-2.915, P = 0.012) and clopidogrel +/- aspirin (OR, 1.82; CI, 1.244-2.663, P=0.002) groups. Patients on AP/AC who experience a TBI requiring an emergent operation do not have an increased risk of mortality compared to patients not on AP/AC.

Changes in patterns of traumatic brain injury in the Michigan Trauma Quality Improvement Program database early in the COVID-19 pandemic.

The authors' objective was to investigate the impact of the global COVID-19 pandemic on hospital presentation and process of care for the treatment of traumatic brain injuries (TBIs). Improved understanding of these effects will inform sociopolitical and hospital policies in response to future pandemics. The Michigan Trauma Quality Improvement Program (MTQIP) database, which contains data from 36 level I and II trauma centers in Michigan and Minnesota, was queried to identify patients who sustained TBI on the basis of head/neck Abbreviated Injury Scale (AIS) codes during the periods of March 13 through July 2 of 2017-2019 (pre-COVID-19 period) and March 13, 2020, through July 2, 2020 (COVID-19 period). Analyses were performed to detect differences in incidence, patient characteristics, injury severity, and outcomes. There was an 18% decrease in the rate of encounters with TBI in the first 8 weeks (March 13 through May 7), followed by a 16% increase during the last 8 weeks (May 8 through July 2), of our COVID-19 period compared with the pre-COVID-19 period. Cumulatively, there was no difference in the rates of encounters with TBI between the COVID-19 and pre-COVID-19 periods. Severity of TBI, as measured with maximum AIS score for the head/neck region and Glasgow Coma Scale score, was also similar between periods. During the COVID-19 period, a greater proportion of patients with TBI presented more than a day after sustaining their injuries (p = 0.046). COVID-19 was also associated with a doubling in the decubitus ulcer rate from 1.0% to 2.1% (p = 0.002) and change in the distribution of discharge status (p = 0.01). Multivariable analysis showed no differences in odds of death/hospice discharge, intensive care unit stay of at least a day, or need for a ventilator for at least a day between the COVID-19 and pre-COVID-19 periods. During the early months of the COVID-19 pandemic, the number of patients who presented with TBI was initially lower than in the years 2017-2019 prior to the pandemic. However, there was a subsequent increase in the rate of encounters with TBI, resulting in overall similar rates of TBI between March 13 through July 2 during the COVID-19 period and during the pre-COVID-19 period. The COVID-19 cohort was also associated with negative impacts on time to presentation, rate of decubitus ulcers, and discharge with supervision. Policies in response to future pandemics must consider the resources necessary to care for patients with TBI.

Reusing personal protective equipment (PPE) did not increase surgical site infection in trauma surgical patients during the COVID-19 pandemic: A retrospective cohort study in Michigan Trauma Centers

BackgroundReuse of personal protective equipment (PPE), masks more specifically, during the COVID-19 pandemic was common. The primary objective of this study was to compare pre-pandemic surgical site infection (SSI) rates prior to reuse of PPE, to pandemic SSI rates after reuse of PPE in trauma surgical patients. MethodsA retrospective cohort analysis collected from the Michigan Trauma Quality Improvement Program database was performed. The pre-COVID cohort was from March 1, 2019 to December 31, 2019 and post-COVID cohort was March 1, 2020 to December 31,2020. Descriptive statistics were used to assess differences between variables in each cohort. ResultsNearly half (49.8%) of our cohort (n = 48,987) was in the post-COVID group. There was no significant difference in frequency of operative intervention between groups (p > .05). There was no significant increase (p > .05) between pre- and post-COVID cohorts for superficial, deep, or organ space SSI when reuse of masks was common. ConclusionReuse of PPE did not lead to an increase in SSI in surgical patients. These findings are consistent with previous studies, but the first to be described in the trauma surgical patient population. Studies such as this may help inform further discussion regarding PPE usage as we continue to emerge from the current pandemic with the continuous threat of future pandemics.

1303: IMPACT OF ANTIPLATELET AND ANTICOAGULANT AGENTS ON EMERGENT SURGERY FOR ORTHOPEDIC TRAUMAS

Introduction: Traumatic injuries bring about an increasing and significant challenge to healthcare systems worldwide. Most traumatic injuries are orthopedic in nature commonly caused by falls and road traffic accidents. A large concern relates to older patients taking anticoagulants and/or antiplatelets (AP/AC) prior to an injury due to the increased risk of hemorrhagic complications. This study utilized the Michigan Trauma Quality Improvement Program (MTQIP) database to determine the effect that AP/AC have on outcomes following emergent surgery for orthopedic traumas. Methods: Patients were included with age >18 years, Maximum Extremity or Pelvic Girdle severity value of abbreviated injury score (AIS) >2, injury severity score (ISS) >5, underwent extremity-related operation (based on the MTQIP Hospital Procedures ICD-10 codes), and underwent a procedure within 24 hours of ED admission. Patients were excluded if they had an AIS >3 in other body region, or no signs of life at initial evaluation. Results: Within the 4,030 patients analyzed, 97 were in the warfarin with or without (+/-) aspirin cohort, 146 in the direct oral anticoagulants (DOAC) +/- aspirin cohort, 140 in the clopidogrel +/- aspirin cohort, and 2,981 in the no AP/AC cohort (control group). After controlling for demographic, comorbid, and clinical characteristics, no significant difference in mortality rates was observed in the treatment groups (p>0.05). However, our subgroup analysis did reveal a significantly higher mortality rate within the warfarin and aspirin subgroup as compared to the control group (odds ratio [OR], 5.849; confidence interval [CI], 1.557-21.975, p=0.009). With regards to hospital complications, there was a significant increase in this outcome within all treatment groups, DOAC +/- aspirin (OR, 1.898; CI, 1.252-2.879, p=0.003), warfarin +/- aspirin (OR, 3.06; CI, 1924-4.868, p< 0.001), clopidogrel +/- aspirin (OR, 2.345; CI, 1.56-3.526, p< 0.001) groups. Conclusions: Patients on AP/AC who experience an orthopedic trauma requiring an emergent operation do not have an increased risk of mortality compared to patients not on AP/AC except for patients on warfarin and aspirin prior to admission.

Effects of Early Chemoprophylaxis in Traumatic Brain Injury and Risk of Venous Thromboembolism.

The optimal timing to initiate venous thromboembolism (VTE) prophylaxis in patients with a traumatic brain injury (TBI) is still unknown. We designed a study to determine the effect that timing of initiation of VTE prophylaxis has on VTE rates in TBI patients. Patient records were obtained from 32 level 1 and 2 trauma centers in the Michigan Trauma Quality Improvement Program from 2008 to 2018. Overall, 5589 patients with a TBI were included and split into cohorts based on VTE prophylaxis initiation time. Outcomes included rate of VTE, mortality, and serious in-hospital complications. There were nine patients (1.3%) in the <24hour group with a VTE as compared to 36 (2.6%) in the 24-48hour group, 51 (4.1%) in the 48-72hour group, and 181 (8.1%) in the >72hour group (P < .001). The adjusted odds of VTE were significantly greater in patients initiated within 48-72hours (AOR 2.861, 95% CI 1.271-6.439) and >72hours (AOR 3.963, 95% CI 1.824-8.612) compared to <24hours. Patients that received VTE prophylaxis within 24hours had similar rates of serious in-hospital complication as patients initiated within 24-48hours (AOR .956, 95% CI .637-1.434) and 48-72hour (AOR 1.132, 95% CI .757-1.692) but less than the >72hour group (AOR 1.662, 95% CI 1.154-2.393) groups. Patients initiated on VTE prophylaxis within 48hours of presentation had lower incidence of VTE without a significant increase in serious complications.

Incorporating the six aims for quality in the analysis of trauma care

ABSTRACT The Institute of Medicine proposed six aims for healthcare quality improvement. Nevertheless, trauma care quality research still focuses on one aim at a time. This research investigates how to incorporate all aims into trauma care quality assessments using data from the Michigan Trauma Quality Improvement Program. Through a literature review, we identified quantifiable metrics for most aims, except for equity and patient-centeredness. We proposed two approaches to build composite scores accounting for equity via an adjustment procedure based on observed disparities. The single- and multi-aim approaches were compared through correlation, concordance of trauma centre categorisations, and hypothetical incentives. The differences in the approaches stemmed mainly from the weights allocated to the different aims. Results indicated the potential value of multi-aim quality assessment and provided insights about implementation challenges and opportunities. The methods are applicable to the preferred metrics; nevertheless, further research is needed in measuring patient-centeredness.

Are motorcycles really “donorcycles”? Examining organ donation rates between unhelmeted and helmeted motorcyclists

Introduction: Motorcycles are colloquially referred to as “donorcycles” among medical staff. However, the actual impact of helmet laws and helmet use on organ donation is unknown. Michigan’s 35-year-old universal helmet law (UHL) was repealed in April 2012 and replaced by a partial-helmet law. We hypothesized that there would be an increase in organ donation rates from unhelmeted motorcyclist fatalities. Methods: Michigan's Gift of Life Michigan organ donation database was queried from April 2008 through May 2015 in conjunction with the Michigan Trauma Quality Improvement Program database from the same time period. All in-hospital motorcycle crash fatalities were examined. Results: A three-fold increase was found in the rate of organ donation for unhelmeted motorcyclists compared to helmeted motorcyclists (p = 0.006). Motorcycle crash fatalities tended to be younger in age after the UHL repeal with an average age of 32.8 years versus 40.8, however, this finding was not statistically significant (p = 0.071). Additionally, there was no significant difference in organ donation rates pre-UHL repeal (2008–2012) versus post-repeal (2012–2015). Conclusions: This is the first study to demonstrate an increased rate of organ donation among unhelmeted motorcyclist fatalities compared to helmeted rider fatalities. There was no significant increase in the rate of organ donation following the Michigan UHL repeal. However, we identified that some motorcycle crash fatalities were from illegally unhelmeted riders in the past, prior to the repeal. Practical Application: Unhelmeted motorcyclists are three times more likely than helmeted riders to become organ donors, possibly due to the well documented increase in severe traumatic brain injuries in this population. From a public health perspective, helmets should be required for all motorcyclists and efforts to advocate in favor of helmet legislation should be supported by trauma systems and health professionals.

Timely Venous Thromboembolism Prophylaxis in Trauma: A Team Approach to Process Improvement.

Venous thromboembolism is a significant complication in trauma. Multisystem injury, advancing age, surgery, and blood transfusion all contribute to the risk of venous thromboembolism in trauma patients. Our Level I trauma center was identified as an outlier with compliance in timely venous thromboembolism prophylaxis in the Michigan Trauma Quality Improvement Program, a statewide collaborative for improving trauma care. The purpose of this study was to provide an evaluation of a performance improvement project to increase the timely administration of venous thromboembolism prophylaxis in admitted trauma patients. Using a Plan-Do-Study-Act method of quality improvement, we initiated a focused, goal-directed team approach that emphasized education, tracking, and feedback. This approach resulted in improved and sustained compliance rates. Resolute focus, audit, and feedback moved our center from a low- to high-performing center for timely venous thromboembolism prophylaxis.

Redefining the Trauma Triage Matrix: The Role of Emergent Interventions

BackgroundA tiered trauma team activation (TTA) system aims to allocate resources proportional to the patient's need based upon injury burden. The current metrics used to evaluate appropriateness of TTA are the trauma triage matrix (TTM), need for trauma intervention (NFTI), and secondary triage assessment tool (STAT). Materials and methodsIn this retrospective study, we compared the effectiveness of the need for an emergent intervention within 6 h (NEI-6) with existing definitions. Data from the Michigan Trauma Quality Improvement Program was utilized. The dataset contains information from 31 level 1 and 2 trauma centers from 2011 to 2017. Inclusion criteria were: adult patients (≥16 y) and ISS ≥5. Results73,818 patients were included in the study. Thirty percentage of trauma patients met criteria for STAT, 21% for NFTI, 20% for TTM, and 13% for NEI-6. NEI-6 was associated with the lowest rate of undertriage at 6.5% (STAT 22.3%, NFTI 14.0%, TTM 14.3%). NEI-6 best predicted undertriage mortality, early mortality, in-hospital mortality, and late (>60 h) mortality. Most patients who met criteria for TTM (58%), NFTI (51%), and STAT (62%) did not require emergent intervention. All four methods had similar rates of early mortality for patients who did not meet criteria (0.3%-0.5%). ConclusionsNEI-6 performs better than TTM, NFTI, and STAT in terms of undertriage, mortality and need for resource utilization. Other methods resulted in significantly more full TTAs than NEI-6 without identifying patients at risk for early mortality. NEI-6 represents a novel tool to determine trauma activation appropriateness.

Association of mortality among trauma patients taking preinjury direct oral anticoagulants versus vitamin K antagonists

BackgroundThe population of patients on anticoagulant or antiplatelet therapy for medical conditions is increasing. The objective of this study was to investigate the effects of preinjury anticoagulation or antiplatelet therapy on outcomes after trauma. MethodsThis cohort study analyzed data from the Michigan Trauma Quality Improvement Program from 2012 to 2017 and included trauma patients age ≥16 years with an Injury Severity Score ≥5 treated at 29 hospitals. The primary outcome was in-hospital mortality. ResultsOf 115,042 trauma patients, 44.2% were women and 78.2% were white with a mean age (standard deviation) of 59.1 (23.2) years. A total of 23,196 patients were on antiplatelet therapy, 3,855 on warfarin, 1,893 on warfarin + antiplatelet agent, 1,306 on a direct oral anticoagulant, and 717 patients on direct oral anticoagulant + antiplatelet therapy. We observed an increased risk of mortality in patients on preinjury antiplatelet (odds ratio [OR] 1.17; 95% confidence interval [CI] 1.02–1.33), warfarin (OR 1.32; 95% CI 1.05–1.65), or warfarin + antiplatelet therapy (OR 1.59; 95% CI 1.18–2.14). Patients on a direct oral anticoagulant only were not at statistically increased risk for mortality. ConclusionPreinjury antiplatelet and/or warfarin use was associated with an increased risk of mortality after traumatic injury. Preinjury direct oral anticoagulant use was not associated with a statistically increased risk of adverse outcomes.

Not Further Specified: Unclassified Orthopedic Injuries in Trauma Registries, Cause for Concern?

BackgroundData accuracy is essential to obtaining correct results and making appropriate conclusions in outcomes research. Few have examined the quality of data that is used in studies involving orthopedic surgery. A nonspecific data entry has the potential to affect the results of a study or the ability to appropriately risk adjust for treatments and outcomes. This study evaluated the proportion of Not Further Specified (NFS) orthopedic injury codes found into two large trauma registries. MaterialsData from the National Trauma Data Bank (NTDB) from 2011 to 2015 and from the Michigan Trauma Quality Improvement Program (MTQIP) 2011-2017 were used. We selected multiple orthopedic injuries classified via the Abbreviated Injury Scale, version 2005 (AIS2005) and calculated the percentage of NFS entries for each specific injury. ResultsThere were a substantial proportion of fractures classified as NFS in each registry, 18.5% (range 2.4%-67.9%) in MTQIP and 27% (range 6.0%-68.5%) in the NTDB. There were significantly more NFS entries when the fractures were complex versus simple in both MTQIP (34.5% versus 9.6%, P < 0.001) and the NTDB (41.8% versus 15.7%, P < 0.001). The level of trauma center affected the proportion of NFS codes differently between the registries. ConclusionsThe proportion of nonspecific entries in these two large trauma registries is concerning. These data can affect the results and conclusions from research studies as well as impact our ability to truly risk adjust for treatments and outcomes. Further studies should explore the reasons for these findings.

Association of Hospital Participation in a Regional Trauma Quality Improvement Collaborative With Patient Outcomes

The American College of Surgeons Trauma Quality Improvement Program (ACS TQIP) provides feedback to hospitals on risk-adjusted outcomes. The Michigan Trauma Quality Improvement Program (MTQIP) goes beyond the provision of feedback alone, focusing on collaborative quality improvement. It is unknown whether the addition of a collaborative approach to benchmark reporting improves outcomes. To evaluate the association of hospital participation in the ACS TQIP (benchmark reporting) or the MTQIP (benchmark reporting and collaborative quality improvement) with outcomes compared with control hospitals that did not participate in either program. In this cohort study, data from the National Trauma Data Bank from 2009 to 2015 were used. A total of 2 373 130 trauma patients 16 years or older with an Injury Severity Score of 5 or more were identified from 98 ACS TQIP hospitals, 23 MTQIP hospitals, and 429 nonparticipating hospitals, based on program participation status in 2011. A difference-in-differences analytic approach was used to evaluate whether hospital participation in the ACS TQIP or the MTQIP was associated with improved outcomes compared with nonparticipation in a quality improvement program. Hospital participation in MTQIP, a quality improvement collaborative, compared with ACS TQIP participation and nonparticipating hospitals. In-hospital mortality, mortality or hospice, major complications, and venous thromboembolism events were assessed. Of the 2 373 130 included trauma patients, 64.2% were men and 73.0% were white, and the mean (SD) age was 50.7 (21.9) years. After accounting for patient factors and preexisting time trends toward improved outcomes, there was a statistically significant improvement in major complications after (vs before) hospital enrollment in the MTQIP collaborative compared with nonparticipating hospitals (odds ratio [OR], 0.89; 95% CI, 0.83-0.95) or ACS TQIP hospitals (OR, 0.88; 95% CI, 0.82-0.94). A similar result was observed for venous thromboembolism (MTQIP vs nonparticipating: OR, 0.78; 95% CI, 0.69-0.88; MTQIP vs ACS TQIP: OR, 0.84; 95% CI, 0.74-0.95), for which MTQIP targeted specific performance improvement efforts. Hospital participation in both ACS TQIP and MTQIP was associated with improvement in mortality or hospice (ACS TQIP vs nonparticipating: OR, 0.90; 95% CI, 0.87-0.93; MTQIP vs nonparticipating: OR, 0.88; 95% CI, 0.81-0.96). Hospitals participating in MTQIP achieved the lowest overall risk-adjusted mortality in the postenrollment period (4.2%; 95% CI, 4.1-4.3). This study demonstrates that hospital participation in a regional collaborative quality improvement program is associated with improved patient outcomes beyond benchmark reporting alone while promoting compliance with processes of care.

The impact of the repeal of Michigan's universal helmet law on traumatic brain injury: A statewide analysis

BackgroundIn April of 2012, Michigan repealed its 35-year-old universal motorcycle helmet law in favor of a partial helmet law, which permits motorcyclists older than 21 years old with sufficient insurance and experience to drive un-helmeted. We evaluated the clinical impact of the repeal. MethodsThe Michigan Trauma Quality Improvement Program's trauma database was queried for motorcycle crash patients between 1/1/09–4/12/12 and between 4/13/12–12/31/14. ResultsThere were 1970 patients in the pre-repeal analysis and 2673 patients in the post-repeal analysis. Following the repeal, patients were more likely to be un-helmeted (p < 0.001) and to have a traumatic brain injury (p < 0.001). Patients were also more likely to require neurosurgical interventions (relative risk 1.4, p = 0.011). ConclusionFollowing the repeal of the universal helmet law, there has been a significant increase in traumatic brain injuries and neurosurgical interventions. This analysis highlights another detrimental impact of the repeal of the universal helmet law.

The Effects of Motorcycle Helmet Legislation on Craniomaxillofacial Injuries.

Motorcycle helmet legislation has been a contentious topic for over a half-century. Benefits of helmet use in motorcycle trauma patients are well documented. In 2012, Michigan repealed its universal motorcycle helmet law in favor of a partial helmet law. The authors describe the early clinical effects on facial injuries throughout Michigan. Retrospective data from the Michigan Trauma Quality Improvement Program trauma database were evaluated. Included were 4643 motorcycle trauma patients presenting to 29 Level I and II trauma centers throughout Michigan 3 years before and after the law repeal (2009 to 2014). Demographics, external cause of injury codes, International Classification of Diseases, Ninth Revision diagnosis codes, and injury details were gathered. The proportion of unhelmeted trauma patients increased from 20 percent to 44 percent. Compared with helmeted trauma patients, unhelmeted patients were nearly twice as likely to sustain craniomaxillofacial injuries (relative risk, 1.90), including fractures (relative risk, 2.02) and soft-tissue injuries (relative risk, 1.94). Unhelmeted patients had a lower Glasgow Coma Scale score and higher Injury Severity Scores. Patients presenting after helmet law repeal were more likely to sustain craniomaxillofacial injuries (relative risk, 1.46), including fractures (relative risk, 1.28) and soft-tissue injuries (relative risk, 1.56). No significant differences were observed for age, sex, Injury Severity Score, or Glasgow Coma Scale score (p > 0.05). This study highlights the significant negative impact of relaxed motorcycle helmet laws leading to an increase in craniomaxillofacial injuries. The authors urge state and national legislators to reestablish universal motorcycle helmet laws.

The Michigan Trauma Quality Improvement Program: Results from a collaborative quality initiative.

American College of Surgeons verified trauma centers and a third-party payer within the state of Michigan built a regional collaborative quality initiative (CQI). The Michigan Trauma Quality Improvement Program began as a pilot in 2008 and expanded to a formal program in 2011. Here, we examine the performance of the collaborative over time with regard to patient outcomes, resource utilization, and process measures. Data from the initial 23 hospitals that joined the CQI in 2011 were analyzed. Performance trends from 2011 to 2015 were evaluated for outcomes, resource utilization, and process measures using univariate analysis. Risk-adjustment was performed to confirm results observed in the unadjusted data. To calculate the potential number of patients impacted by the CQI program, the maximum absolute change was multiplied by the number of trauma patients treated in the 23 hospitals during 2015. Membership in a CQI program significantly reduced serious complications (8.5 vs. 7.3%, p = 0.002), decreased resource utilization, and improved process measure execution in trauma patients over 5 years time. Similar results were obtained in unadjusted and risk-adjusted analyses. The CQI program potentially avoided inferior vena cava filter placement in 167 patients annually. Decreased venous thromboembolism rates mirrored increased compliance with venous thromboembolism pharmacologic prophylaxis. This study confirms our hypothesis that participation in a regional CQI improves patient outcomes and decreases resource utilization while promoting compliance with processes of care.

Quality Improvement in the Surgical Intensive Care Unit

Programs to support clinical benchmarking of surgical outcomes have grown dramatically over the past decade. Selection of an appropriate project and preplanning with regard to strategy are often more important than management skill alone when undertaking and performing successful quality improvement in the intensive care unit (ICU) setting. This review covers an overview of a medical and surgical quality system, development of an ICU quality improvement program, scoring systems: risk assessment, evidence-based medicine and protocols, and a quality improvement framework. Figures show structure of the ICU quality improvement team, the C-index statistic reflecting the ability of a model to predict which patients will have the outcome of interest, a Shewhart statistical process control chart, venous thromboembolism (VTE) events by report number, and changes in the type of VTE prophylaxis agent administered over time. Tables list Blue Cross Blue Shield of Michigan/Blue Care Network-sponsored, registry-based collaborative quality initiatives, critical care societies’ collaborative-based quality improvement task force priorities for performance measurement, possible ICU quality measures, predictive scoring systems, and multivariate and propensity score analysis of the Michigan Trauma Quality Improvement Program pilot data for VTE events and type of VTE prophylaxis. This review contains 5 highly rendered figures, 5 tables, and 59 references
