RESUMO
INTRODUCTION: Like civilian health systems, the United States Military Health System (MHS) confronts challenges in achieving the aims of reducing cost, and improving quality, access, and safety, but historically has lacked coordinated health services research (HSR) capabilities that enabled knowledge translation and iterative learning from its wealth of data. A military-civilian academic partnership called the Comparative Effectiveness and Provider-Induced Demand Collaboration (EPIC), formed in 2011, demonstrated early proof-of-concept in using the MHS claims database for research focused on drivers of variation in health care. This existing partnership was reorganized in 2015 and its topics expanded to meet the need for HSR in support of emerging priorities and to develop current and HSR capacity within the MHS. MATERIALS AND METHODS: A Donabedian framework of structure, process, and outcomes was applied to support the project, through a core of principal investigators, researchers, analysts, and administrators. Within this framework, new researchers and student trainees learn foundations of HSR while performing secondary analysis of claims data from the MHS Data Repository (MDR) focusing on Health and Readiness, Pediatrics, Policy, Surgery, Trauma, and Women's Health. RESULTS: Since 2015, the project has trained 25 faculty, staff, and providers; 51 students and residents; 21 research fellows across multiple disciplines; and as of 2022, produced 107 peer-reviewed publications and 130 conference presentations, across all five themes and six cores. Research results have been incorporated into Federal and professional policy guidelines. Major research areas include opioid usage and prescribing, value-based care, and racial disparities. EPIC researchers provide direct support to MHS leaders and enabling expertise to clinical providers. CONCLUSIONS: EPIC, through its Donabedian framework and utilization of the MHS Data Repository as a research tool, generates actionable findings and builds capacity for continued HSR across the MHS. Eight years after its reorganization in 2015, EPIC continues to provide a platform for capacity building and knowledge translation.

INTRODUCTION: Solitary pulmonary nodules (SPNs) are common, but the clinical relevance of these nodules is unknown. Utilizing current screening guidelines, we sought to better characterize the national incidence of clinically important SPNs within the largest universal health care system in the nation. MATERIALS AND METHODS: TRICARE data were queried to identify SPNs for ages 18-64 years. SPNs that had been diagnosed within a year with no prior oncologic history were included to ensure true incidence. A proprietary algorithm was applied to determine clinically significant nodules. Further analysis characterized incidence by age grouping, gender, region, military branch, and beneficiary status. RESULTS: A total of 229,552 SPNs were identified with a 60% reduction seen after application of the clinical significance algorithm (N = 88,628). The incidence increased in each decade of life (all P < 0.01). Adjusted incident rate ratios were significantly higher for SPNs detected in the Midwest and Western regions. The incident rate ratio was also higher in females (1.05, confidence interval [CI] 1.018, P = 0.001) as well as non-active duty members (dependents = 1.4 and retired = 1.6, respectively, CIs 1.383-1.492 and 1.591-1.638, P < 0.01). The incidence calculated per 1,000 patients overall was 3.1/1,000. Ages 44-54 years had an incidence of 5.5/1,000 patients, which is higher than the previously reported incidence of < 5.0 nationally for the same age group. CONCLUSIONS: This analysis represents the largest evaluation of SPNs to date combined with clinical relevance adjustment. These data suggest a higher incidence of clinically significant SPNs starting at an age of 44 years in nonmilitary or retired women localized to the Midwest and Western regions of the United States.

Antibiotics and drainage have largely replaced hepatic resection for the treatment of liver abscesses in the modern era; however, in cases caused by a rare strain of Klebsiella pneumoniae with a hypermucoviscous phenotype, more aggressive hepatic resection may be required. The patient is a 34-year-old male who presented to Landstuhl Regional Medical Center with a week of epigastric pain. His workup revealed a 6 cm liver abscess with growth to 10 cm in 48 hours. He underwent multiple drainage procedures at Landstuhl and then was transferred to Walter Reed where further surgical drainage was performed. Initial cultures demonstrated K. pneumoniae. He clinically improved and was able to discharge after a 2 week hospitalization. His final remaining surgical drain was removed as an outpatient, but 48 hours after removal, he was admitted to the intensive care unit in septic shock. Imaging revealed a 12 cm liver abscess, and cultures verified hypermucoviscous Klebsiella. After multidisciplinary discussion and counseling, he underwent an open right partial hepatectomy. Postoperatively he gradually recovered from his sepsis and major operation and then returned to his home in Landstuhl. This is a case of a rare hypermucoviscous variant of K. pneumoniae causing a liver abscess resistant to multiple drainage procedures, ultimately requiring open hepatic surgical resection for source control. This remains a last-resort option in the treatment of liver abscesses and should be considered early when caused by this rare strain of Klebsiella.

INTRODUCTION: Military-civilian partnerships are crucial to maintaining the skills of active duty surgeons and sustaining readiness. There have been no publications to date that report the quantitative effect of these partnerships on academic research. To address this question, the Hirsch indices (H-indices) of active duty surgeons with a civilian affiliation (CA) were compared to those without. As a secondary outcome, H-indices of military surgeons with and without an appointment to the Uniformed Services University (USU) were similarly compared. We hypothesized that military surgeons with a CA would have a higher H-index as compared to those without. MATERIALS AND METHODS: Rosters of active duty military surgeons were obtained confidentially through each branch consultant. H-indices were found on Scopus. Graduation dates and hospital affiliations were identified via public Doximity, LinkedIn profiles, and hospital biographies. Rosters were cross-referenced with USU appointments. Stata software was used for final analysis. RESULTS: Military surgeons without a civilian association have a median H-index of 2 versus 3 in those with such an affiliation (P = .0002). This pattern is also seen in average number of publications, at 3 and 5 articles (P < .0001). When further stratified by branch, Air Force surgeons have median H-indices of 2.5 and 1 with and without a CA, respectively (P = .0007). The Army surgeons follow a similar pattern, with median H-indices of 5 and 3 for those with and without affiliations, respectively (P = .0021). This significance does not hold in the Naval subgroup. Similar results are found for the secondary outcome of USU appointment, with median H-indices of 3 and 2 in those with and without CAs, respectively (P < .0001). In the multivariable negative binomial regression model, both CA and USU appointment significantly increased H-index in the overall cohort, with incidence rate ratios of 1.32 (95% CI = 1.08, 1.61) and 1.56 (95% CI = 1.28, 1.91), respectively. CONCLUSION: This article provides objective evidence that there is a benefit to military-civilian partnerships on the academic output of military surgeons. These relationships should continue to be fostered and expanded.
RESUMO
OBJECTIVE: Ongoing health care reforms within the US Military Health System (MHS) are expected to shift >1.9 million MHS beneficiaries from military treatment facilities (MTFs) into local civilian hospitals over the next 1-2 years. The objective of this study was to examine how such health care reforms are likely to affect the quality of MHS care. DATA SOURCES: Adult MHS beneficiaries, aged 18-64 years, treated in MTFs (under a program known as Direct Care) were compared against (1) MHS beneficiaries treated in locally available civilian hospitals (under a program known as Purchased Care) and (2) similarly-aged adult civilian patients across the United States. MHS beneficiaries in Direct and Purchased Care were identified from fiscal-year 2016-2018 MHS inpatient claims. National inpatients were identified in the 2017 Nationwide Readmissions Database. STUDY DESIGN: Retrospective cohort. DATA COLLECTION: Differences in quality were compared using two sets of quality metrics endorsed by the US Agency for Healthcare Research and Quality (AHRQ): Inpatient Quality Indicators, 19 quality metrics that look at differences in in-hospital mortality, and Patient Safety Indicators, 18 quality metrics that look at differences in in-hospital morbidity and adverse events. Among MHS beneficiaries (Direct and Purchased Care), we further simulated what changes in quality indicators might look like under various proposed scenarios of reduced access to Direct Care. PRINCIPAL FINDINGS: A total of 502,252 MHS admissions from 37 MTFs and surrounding civilian hospitals were included (326,076 Direct Care, 179,176 Purchased Care). Nationwide, 9.34 million adult admissions from 2453 hospitals were included. On average, MHS beneficiaries treated in MTFs experienced better inpatient quality and improved patient safety compared with MHS beneficiaries treated in locally available civilian hospitals (e.g., summary observed-to-expected ratio for medical mortality: 0.98 vs. 1.03, p < 0.001) and adult patients across the United States (0.98 vs. 1.02, p < 0.001). Simulations of proposed changes resulted in consistently worse outcomes for MHS patients, whether reducing MTF access by 10%, 20%, or 50% nationwide; limiting MTF access to active-duty beneficiaries; or closing MTFs with the worst performance on patient safety (p < 0.001 for overall quality indicators for each). CONCLUSIONS: Reducing access to MTFs could result in significant harm to MHS patients. The results underscore the importance of health-policy planning based on evidence-based evaluation and the need to consider the consequential downstream effects caused by changes in access to care.

INTRODUCTION: Facing the COVID-19 pandemic, many hospitals implemented severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) screening protocols before aerosol-generating procedures (AGPs) in an effort to protect patients and health care workers. Given the limited prior evidence on the effectiveness of such protocols, we report the process improvement experience at a military treatment facility. MATERIALS AND METHODS: We evaluated the outcomes of patients undergoing AGPs from March to September 2020, divided into three cohorts: a preprotocol (PP) cohort who did not receive screening, an early testing (ET) cohort representing the early months of the screening protocol, and a late testing (LT) cohort managed under adaptive modifications to the screening protocol. We recorded identifiable post-procedure COVID-19 diagnoses. The study was approved as a process improvement protocol and was determined not to meet criteria for human subject research through an institutional approval process. RESULTS: Across the three cohorts, 4520 procedures were performed: 422 PP, 1297 ET, and 2801 LT. Among 4098 procedures in the ET and LT cohorts, 12 asymptomatic patients tested positive for SARS-CoV-2 (0.29% positivity rate). One left the health system before completing the procedure and another proceeded urgently under COVID precautions, while 10 were rescheduled and completed at a later date; 7 were cleared using a test-based strategy, while 3 were cleared using a time-based strategy. Of 445 patients who had SARS-CoV-2 tests performed within 30 days following their procedures, three patients with negative preoperative tests had a positive test within 30 days, all in the LT cohort but had evidence of acquiring the infection after the procedure or had a false-positive test. CONCLUSIONS: Our strategy of preprocedural SARS-CoV-2 testing successfully identified asymptomatic infected patients before surgery. Care was delayed for most of these patients without apparent detriment. Adaptation to a time-based strategy for clearance might reduce such delays, but other considerations may still influence how soon procedures should be completed after a positive test.
RESUMO
INTRODUCTION: During the Global War on Terrorism, many US Military service members sustained injuries with potentially long-lasting functional limitations and chronic pain. We sought to understand the patterns of prescription opioid use among service members injured in combat. METHODS: We queried the Military Health System Data Repository to identify service members injured in combat between 2007 and 2011. Sociodemographics, injury characteristics, treatment information, and costs of care were abstracted for all eligible patients. We surveyed for prescription opioid utilization subsequent to hospital discharge and through 2018. Negative binomial regression was used to identify factors associated with cumulative prescription opioid use. RESULTS: We identified 3,981 service members with combat-related injuries presenting during the study period. The median age was 24 years (interquartile range [IQR], 22-29 years), 98.5% were male, and the median follow-up was 3.3 years. During the study period, 98% (n = 3,910) of patients were prescribed opioids at least once and were prescribed opioids for a median of 29 days (IQR, 9-85 days) per patient-year of follow-up. While nearly all patients (96%; n = 3,157) discontinued use within 6 months, 91% (n = 2,882) were prescribed opioids again after initially discontinuing opioids. Following regression analysis, patients with preinjury opioid exposure, more severe injuries, blast injuries, and enlisted rank had higher cumulative opioid use. Patients who discontinued opioids within 6 months had an unadjusted median total health care cost of US $97,800 (IQR, US $42,364-237,135) compared with US $230,524 (IQR, US $134,387-370,102) among those who did not discontinue opioids within 6 months (p < 0.001). CONCLUSION: Nearly all service members injured in combat were prescribed opioids during treatment, and the vast majority experienced multiple episodes of prescription opioid use. Only 4% of the population met the criteria for sustained prescription opioid use at 6 months following discharge. Early discontinuation may not translate to long-term opioid cessation in this population. LEVEL OF EVIDENCE: Epidemiology study, level III.

BACKGROUND: As the opioid crisis continues, it is critical that health care providers ensure they are not overprescribing opioid medications. At our institution (Walter Reed National Military Medical Center, Bethesda, MD), postoperative patients after breast surgeries are discharged with variable amounts of opioid medications. However, many patients report minimal opioid use. The objectives of this study were to characterize postoperative opioid usage and prescribing practices for patients undergoing various breast surgeries and to recommend the number of opioid pills for discharge for each procedure. METHODS: This was a prospective, single-institution study of all patients undergoing breast surgery from October 2018 to 2019. All patients were enrolled in our institution's enhanced recovery after surgery protocol. Patients were given questionnaires at their 2-week postoperative clinic appointment that evaluated perioperative pain and use of pain medications. The electronic medical record was reviewed to obtain additional information. Appropriate parametric and nonparametric tests were used for analysis. RESULTS: A total of 190 breast surgery patients completed the survey. We observed no significant differences in pain scores except between re-excision and mastectomy. Of these patients, 99% were prescribed opioids; however, only 53% of patients used them. Of those patients who were prescribed opioids, on average, all were prescribed more pills than were used. CONCLUSION: Our study demonstrates that it is possible to discharge all breast surgery patients with fewer than 10 opioid pills, except for special circumstances. This is the first study to provide a set of specific recommended discharge medications. Utilization of an enhanced recovery after surgery protocol with standardized discharge opioids can be used successfully to reduce the number of opioids prescribed to patients.

BACKGROUND: The National Surgical Quality Improvement Program (NSQIP) has become a prevalent tool for quality improvement. At our tertiary military hospital, NSQIP collects 20% of eligible cases. We implemented an emergency general surgery (EGS) registry to prospectively review all EGS cases. We compared our EGS registry with NSQIP, hypothesizing that NSQIP sampling under-represents EGS outcomes. METHODS: A formal EGS Process Improvement Program was implemented in 2016. From 2016 to 2018, the four most common operations were laparoscopic appendectomy, laparoscopic cholecystectomy, surgery for small bowel obstruction, and nonelective hernia repair. Outcomes were compared between the EGS registry and NSQIP abstracted cases. RESULTS: In 2016, the EGS registry identified 11/112 (9.8%) patients with a complication. National Surgical Quality Improvement Program abstracted 16% of EGS cases with 16.7% (3/18) of patients having a complication. In 2017, the EGS registry identified 10/87 (11.5%) cases with complications. National Surgical Quality Improvement Program abstracted 23% of EGS with zero complications. In 2018, the EGS registry identified 9.5% of 74 cases with complications. National Surgical Quality Improvement Program abstracted 15% of EGS cases with zero complications. CONCLUSIONS: National Surgical Quality Improvement Program did not capture many important EGS outcomes. In 2 of 3 years, NSQIP did not identify a single complication for EGS. National Surgical Quality Improvement Program alone may be insufficient to target EGS improvements.

INTRODUCTION: Super-utilizers (patients with 4 or more emergency department [ED] visits a year) account for 10% to 26% of all ED visits and are responsible for a growing proportion of healthcare expenditures. Patients recognize the ED as a reliable provider of acute care, as well as a timely resource for diagnosis and treatment. The value of ED care is indisputable in critical and emergent conditions, but in the case of non-urgent conditions, ED utilization may represent an inefficiency in the healthcare system. We sought to identify patient and clinical characteristics associated with ED super-utilization in a universally insured population. MATERIAL AND METHODS: We performed a retrospective cohort study using TRICARE claims data from the Military Health System Data Repository (2011-2015). We reviewed the claims data of all adult patients (aged 18-64 years) who had at least one encounter at the ED for any cause. Multivariable logistic regression was used to determine independent factors associated with ED super-utilization. RESULTS: Factors associated with increased odds of ED super-utilization included Charlson Score ≥2 (adjusted odds ratio [aOR] 1.98, 95% confidence interval [CI]: 1.90-2.06), being eligible for Medicare (aOR 1.95, 95% CI: 1.90-2.01), and female sex (aOR 1.35, 95% CI: 1.33-1.37). Active duty service members (aOR 0.69, 95% CI 0.68-0.72) and beneficiaries with higher sponsor-rank (Officers: aOR 0.50, 95% CI: 0.55-0.57; Senior enlisted: aOR 0.82, 95% CI: 0.81-0.83) had lower odds of ED super-utilization. The most common primary diagnoses for ED visits among super-utilizers were abdominal pain, headache and migraine, chest pain, urinary tract infection, nausea and vomiting, and low back pain. CONCLUSIONS: Risk of ED super-utilization appears to increase with age and diminished health status. Patient demographic and clinical characteristics of ED super-utilization identified in this study can be used to formulate healthcare policies addressing gaps in primary care in diagnoses associated with ED super-utilization and develop interventions to address modifiable risk factors of ED utilization.

INTRODUCTION: Emergency department (ED) utilization represents an expensive and growing means of accessing care for a variety of conditions. Prior studies have characterized ED utilization in the general population. We aim to identify the clinical conditions that drive ED utilization in a universally insured population and the impacts of care setting on ED use and admissions in the U.S. Military Health System. METHODS: We queried TRICARE claims data from October 1, 2012, to September 30, 2015, to identify all ED visits for adult patients (age 18-64). The primary presenting diagnoses of all ED visits and those leading to admission are presented with descriptive statistics. Logistic regression was used to identify clinical and sociodemographic factors associated with admission from the ED. RESULTS: A total of 4,687,205 ED visits were identified, of which 46% took place in the DoD healthcare facilities (direct care). The most common diagnoses across all ED visits were abdominal pain, chest pain, headache, nausea and vomiting, and urinary tract infection. A total of 270,127 (5.8%) ED visits led to inpatient admission. The most common diagnoses leading to admission were chest pain, abdominal pain, depression, conditions relating to acute psychological stress, and pneumonia. For patients presenting with 1 of the 10 most common ED diagnoses, those who were seen at a civilian ED were significantly less likely to be admitted (3.4%) compared to direct care facilities (4.1%) in an adjusted logistic regression model (Adjusted Odds Ratio 0.40 [95% CI: 0.40-0.41], P < .001). CONCLUSIONS: Ultimately, we show that abdominal pain and chest pain are the most common reasons for presentation to the ED in the Military Health System and the most common presenting diagnoses for admission from the ED. Among patients presenting with the most common ED conditions, direct care EDs were significantly more likely to admit patients than civilian facilities.

BACKGROUND: Rib fractures are painful injuries that are treated with aggressive analgesia, which can include opioids. We sought to evaluate the patterns and predictors of opioid prescription and sustained use for rib fracture patients to identify opportunities for opiate reduction. METHODS: We used TRICARE claims data (2006-2014) to identify adult (18-64 years) patients presenting to the emergency department with rib fracture(s) and isolated chest trauma. We used logistic regression and Cox proportional hazards model to identify factors associated with opioid prescription and duration of use. RESULTS: We identified 29,943 patients meeting inclusion criteria, and 2,542 (9%) patients were prescribed opioids. When prescribed, the median duration opioid use was 16 days (interquartile range 6-31) for opioid naïve patients, compared with 36 days (interquartile range 15-134) for those with prior opioid exposure. Increased number of ribs fractured (6+ fractures) (odds ratio 2.96 [95% confidence interval 2.23-3.94], P < .001) and prior opioid exposure (odds ratio 32.95 [29.36-36.99], P < .001) were significant predictors of initial opioid prescription. Patients with prior opioid exposure (hazard ratio 0.47 [0.43-0.52], P < .001) had lower likelihood of opioid discontinuation. Injury characteristics did not significantly predict discontinuation. CONCLUSION: Prior opioid exposure was the strongest predictor of sustained opioid use after rib fractures, while the severity of injury did not predict the duration of use.

BACKGROUND: Preoperative magnetic resonance imaging (MRI) utilization in breast cancer treatment has increased significantly over the past 2 decades, but its use continues to have interprovider variability and disputed clinical indications. OBJECTIVE: The aim of this study was to evaluate non-clinical factors associated with preoperative breast MRI utilization. METHODS: This study utilized TRICARE claims data from 2006 to 2015. TRICARE provides health benefits for active duty service members, retirees, and their dependents at both military (direct care with salaried physicians) and civilian (purchased care under fee-for-service structure) facilities. We studied patients aged 25-64 years with a breast cancer diagnosis who had undergone mammogram/ultrasound (MMG/US) alone or with subsequent breast MRI prior to surgery. Facility characteristics included urban-rural location according to the National Center for Health Statistics classification. Adjusted multivariable logistic regression tests were used to identify independent factors associated with preoperative breast MRI utilization. RESULTS: Of the 25,392 identified patients, 64.7% (n = 16,428) received preoperative MMG/US alone, while 35.3% (n = 8964) underwent additional MRI. Younger age, Charlson Comorbidity Index score ≥ 2, active duty or retired beneficiary category, officer rank (surrogate for socioeconomic status), Air Force service branch, metropolitan location, and purchased care were associated with an increased likelihood of preoperative MRI utilization. Non-metropolitan location and Navy service branch were associated with decreased MRI use. CONCLUSION: After controlling for expected clinical risk factors, patients were more likely to receive additional MRI when treated at metropolitan facilities or through the fee-for-service system. Both associations may point toward non-clinical incentives to perform MRI in the treatment of breast cancer.

BACKGROUND: In prior reports from population-based databases, black patients with extremity soft tissue sarcoma (ESTS) have lower reported rates of limb-sparing surgery and adjuvant treatment. The objective of this study was to compare the multimodality treatment of ESTS between black and white patients within a universally insured and equal-access health care system. METHODS: Claims data from TRICARE, the US Department of Defense insurance plan that provides health care coverage for 9 million active-duty personnel, retirees, and dependents, were queried for patients younger than 65 y with ESTS who underwent limb-sparing surgery or amputation between 2006 and 2014 and identified as black or white race. Multivariable logistic regression analysis was used to evaluate the impact of race on the utilization of surgery, chemotherapy, and radiation. RESULTS: Of the 719 patients included for analysis, 605 patients (84%) were white and 114 (16%) were black. Compared with whites, blacks had the same likelihood of receiving limb-sparing surgery (odds ratio [OR], 0.861; 95% confidence interval [95% CI], 0.284-2.611; P = 0.79), neoadjuvant radiation (OR, 1.177; 95% CI, 0.204-1.319; P = 0.34), and neoadjuvant (OR, 0.852; 95% CI, 0.554-1.311; P = 0.47) and adjuvant (OR, 1.211; 95% CI, 0.911-1.611; P = 0.19) chemotherapy; blacks more likely to receive adjuvant radiation (OR, 1.917; 95% CI, 1.162-3.162; P = 0.011). CONCLUSIONS: In a universally insured population, racial differences in the rates of limb-sparing surgery for ESTS are significantly mitigated compared with prior reports. Biologic or disease factors that could not be accounted for in this study may contribute to the increased use of adjuvant radiation among black patients.

BACKGROUND: Low hospital volume for emergency general surgery (EGS) procedures is associated with worse patient outcomes within the civilian health care system. The military maintains treatment facilities (MTFs) in remote locations to provide access to service members and their families. We sought to determine if patients treated at low-volume MTFs for EGS conditions experience worse outcomes compared with high-volume centers. MATERIALS AND METHODS: We analyzed TRICARE data from 2006 to 2014. Patients were identified using an established coding algorithm for EGS admission. MTFs were divided into quartiles based on annual EGS volume. Outcomes included 30-d mortality, complications, and readmissions. Logistic regression models adjusting for clinical and sociodemographic differences in case-mix including EGS condition, surgical intervention, and comorbidities were used to determine the influence of hospital volume on outcomes. RESULTS: We identified 106,915 patients treated for an EGS condition at 79 MTFs. The overall mortality rate was 0.21%, with complications occurring in 8.55% and readmissions in 4.45%. After risk adjustment, lowest-volume MTFs did not demonstrate significantly higher odds of mortality (OR: 2.02, CI: 0.45-9.06) or readmissions (OR: 0.77, CI: 0.54-1.11) compared with the highest-volume centers. Lowest-volume facilities exhibited a lower likelihood of complications (OR: 0.76, CI: 0.59-0.98). CONCLUSIONS: EGS patients treated at low-volume MTFs did not experience worse clinical outcomes when compared with high-volume centers. Remote MTFs appear to provide care for EGS conditions comparable with that of high-volume facilities. Our findings speak against the need to reduce services at small, critical access facilities within the military health care system.

In an effort to improve surgical quality and reduce clinical variability, the Military Health System (MHS) expanded its participation in the National Surgical Quality Improvement Program to all military hospitals beginning in 2015. This expansion and a partnership with the American College of Surgeons laid the foundation for a surgical quality collaborative in the MHS. We review the history of the program in the MHS and the activities that have contributed to developing the collaborative. We also report promising trends in surgical outcomes at hospitals that were already participating in the program in 2014, when a critical MHS review identified areas for improvement in surgical care. We conclude with a discussion of possible lessons for other health systems and challenges ahead for the MHS, now that full enrollment in the program has been completed.

BACKGROUND: Index length of stay (LOS) and readmissions are viewed as important quality measures. However, these metrics represent competing demands as an inordinate reduction in LOS may lead to unplanned readmissions. We sought to assess the optimal LOS associated with the lowest 90-d readmission rate following discharge after common surgical procedures. MATERIALS AND METHODS: This was a retrospective study relying on Tricare claims. We identified all eligible adult patients (18-64 y) receiving a series of common surgical procedures between 2006 and 2014. We used a generalized additive model with spline regression to determine the optimal LOS associated with the lowest 90-d risk of readmission. RESULTS: Ninety-day readmission rates varied from 6.03% to 34.69%. Most procedures exhibited a logit linear relationship, with the lowest risk of readmission evident on postoperative day-1 and increasing thereafter. Among the more invasive procedures (e.g., esophagectomy and radical cystectomy), a U-shaped relationship was realized, indicating that expedited discharge would increase the potential for readmission as would any extended hospital LOS. For these procedures, the ideal index LOS appeared to be 6-7 d for radical cystectomy and 12-13 d for esophagectomy. CONCLUSIONS: Our results support the practice of discharging patients as soon as clinically feasible after hip and knee arthroplasty, lumbar spine surgery, hernia repair, appendectomy, nephrectomy, and colectomy. Among esophagectomy or radical cystectomy, there is a well-defined optimal index admission period and discharge outside this window appears to be detrimental. Our results suggest that invasive procedures appear to possess a unique "signature" when it comes to optimal LOS.

BACKGROUND: Thirty-day complications frequently serve in the surgical literature as a quality indicator. This metric is not meant to capture the full array of complication resulting from surgical intervention. However, this period is largely based on convention, with little evidence to support it. This study sought to determine the optimal surveillance period for postsurgical complications, defined as the shortest period that also encompassed the highest proportion of postsurgical adverse events. METHODS: TRICARE data (2006-2014) were queried for adult (18-64 y) patients who underwent one of 11 surgical procedures. Patients were assessed for complications up to 90 d after surgery. Kaplan-Meier curves, linear spline regression models at each incremental postsurgical day, and adjusted R-squared values were used to identify critical time point cutoffs for the surveillance of complications. Optimal length of surveillance was defined as the postsurgical day on which the model demonstrated the highest R-squared value. A supplemental analysis considered these measures for orthopedic and general surgical procedures. RESULTS: One lakh ninety-eight patients met the inclusion criteria. A total of 21.8% patients experienced at least one complication during the follow-up period, with 59% occurring within the first 15 d. Kaplan-Meier curves for complications showed a demonstrable inflection before 20 d and 14-15 d possessed the highest R-squared values. CONCLUSIONS: In this analysis, the optimal surveillance period for postsurgical complications was 15 d. While the conventional 30-d period may still be appropriate for a variety of reasons, the shorter interval identified here may represent a superior quality measure specific to surgical practice.
