The Military-Civilian Partnership Quality Improvement Program Concept: A Process to Improve Data Collection and Outcomes Assessment.

INTRODUCTION: Military-Civilian Partnerships (MCPs) are vital for maintaining the deployment readiness of military health care physicians. However, tracking their clinical activity has proven to be challenging. In this study, we introduce a locally driven process aimed at the passive collection of external clinical workload data. This process is designed to facilitate an assessment of MCP physicians' deployment readiness and the effectiveness of individual MCPs. MATERIALS AND METHODS: From March 2020 to February 2023, we conducted a series of quality improvement projects at the Wright Patterson Medical Center (WPMC) to enhance our data collection efforts for MCP physicians. Our methodology encompassed several steps. First, we assessed our existing data collection processes and their outcomes to identify improvement areas. Next, we tested various data collection methods, including self-reporting, a web-based smart phone application, and an automated process based on billing or electronic health record data. Following this, we refined our data collection process, incorporating the identified improvements and systematically tracking outcomes. Finally, we evaluated the refined process in 2 different MCPs, with our primary outcome measure being the collection of monthly health care data. RESULTS: Our examination at the WPMC initially identified several weaknesses in our established data collection efforts. These included unclear responsibility for data collection within the Medical Group, an inadequate roster of participating MCP physicians, and underutilization of military and community resources for data collection. To address these issues, we implemented revisions to our data collection process. These revisions included establishing clear responsibility for data collection through the Office of Military-Civilian Partnerships, introducing a regular "roll call" to match physicians to MCP agreements, passively collecting data each month through civilian partner billing or information technology offices, and integrating Office of Military-Civilian Partnership efforts into regular executive committee meetings. As a result, we observed a 4-fold increase in monthly data capture at WPMC, with similar gains when the refined process was implemented at an Air Force Center for the Sustainment of Trauma and Readiness Skills site. CONCLUSIONS: The Military-Civilian Partnership Quality Improvement Program concept is an effective, locally driven process for enhancing the capture of external clinical workload data for military providers engaged in MCPs. Further examination of the Military-Civilian Partnership Quality Improvement Program process is needed at other institutions to validate its effectiveness and build a community of MCP champions.

The Air Force Visiting Surgeon Program: Development, Outcomes, and Future Application.

INTRODUCTION: Active duty service members and their families have limited access to subspecialty surgical care when assigned OCONUS. To address this issue, the Air Force Visiting Surgeon Program (VSP) was created to push subspecialty care to these locations. Visiting Surgeon Program was accomplished using temporary duty (TDY) orders. We conducted this 12-year review, 2009-2021, of the program to assess objective measures of impact, identify key lessons learned, and consider the program's future. MATERIALS AND METHODS: In 2009, the senior author, Col Latham, performed a cost analysis of plastic surgery care provided at OCONUS installations and found that TRICARE Overseas often paid rates substantially higher than a TDY assignment for a single procedure. To improve beneficiaries' access to care while providing a cost savings to the health care system, 2-week plastic surgery missions were proposed to interested OCONUS military treatment facilities (MTFs). Ultimately, four sites selected to host the program in Alaska, Italy, England, and Japan. These sites were selected based on patient volumes, operating room capacity, and local command and surgeon support. By 2015, the Air Force formalized the program via Air Force Instruction 44-102 which outlined roles and responsibilities of MTF Commanders; established points of contact; and instituted key safety measures. RESULTS: To date, 58 missions have been completed by 21 surgeons through the VSP at Aviano Air Base (Italy; 24.1%), Joint Base Elmendorf-Richardson (Alaska; 31.0%), Royal Air Force Lakenheath (England; 27.6%), and Yokota Air Base (Japan; 17.2%). While primarily an Air Force program, 17% (10/58) of missions were supported Army or Navy surgeons. Overall, 2,000 patient consultations and 865 surgical cases were performed avoiding $6.7 million in cost. In addition to direct beneficiary care, the VSP also contributed to the participating surgeon and host surgical teams mission readiness. CONCLUSIONS: The VSP provides a template to make select subspecialty surgical care available in a cost-effective manner across the military health system, while also providing a model for the forward deployment of military plastic surgeons and triservice collaboration.

Hospital-based, acute care within 30 days following discharge for acute burn injury.

BACKGROUND: While the acute management of burn injury has received substantial attention, patients may undergo additional hospital based, acute care following initial management. We conducted this study to quantify and describe patients' full hospital based, acute care needs within 30 days following an acute burn injury. METHODS: Using Florida, Nebraska, and New York state inpatient and emergency department databases, we identified adult patients discharged for an acute burn injury from January 1, 2010-November 30, 2014. The primary outcome was the frequency of hospital based, acute care (ED visit or hospital admission) within 30 days of initial discharge. Multivariable logistic regression modeling was used to identify patient factors associated with more frequent hospital based, acute care in the overall population. RESULTS: The final sample included 126,685 patients who sustained an acute burn injury and were initially managed through the ED (88.3%) or by hospital admission (11.7%). Overall, 16.5% of patients experienced at least one hospital based, acute care encounter within 30 days of discharge of their initial encounter. Most commonly, these were ED visits not undergoing hospital admission for wound care, ongoing burn care, or infectious complications. Patient-level factors associated with more frequent encounters included a history of opioid misuse or abuse (Adjusted Odds Ratio = 2.23, [95% Confidence Interval 2.01-2.47]), chronic obstructive pulmonary disease (AOR = 1.25, [1.12-1.38]), diabetes mellitus (AOR = 1.13, [1.04-1.23]), and mental health diagnoses (AOR = 1.22, [1.11-1.34]). CONCLUSIONS: Hospital based, acute care encounters are common after initial burn management. Further efforts are needed to improve the transition to outpatient care.

Combating the "Peacetime Effect" in Military Plastic Surgery: Implications for Mission Readiness.

Military treatment facility-assigned surgeons face numerous challenges in maintaining critical wartime skills, including the "peacetime effect" and the "dual mission." Using the field of plastic surgery to illustrate these issues, we contrast plastic surgeons' contributions to combat casualty care with primary data describing plastic surgeons' clinical practice in many military hospitals. Then, we outline the current administrative mechanisms being promoted at the enterprise-level for surgeons to gain a more mission-focused, clinical practice, while also examining significant shortcomings in these policies. Finally, we conclude with a call to action for the military surgical community to accelerate change in the development of more robust clinical practices for our surgeons, or potentially lose our ability to field a ready surgical force.

Pediatric Hand and Upper Extremity Injuries Presenting to Emergency Departments in the United States: Epidemiology and Health Care-Associated Costs.

Background: Upper extremity injuries represent one of the most common pediatric conditions presenting to emergency departments (EDs) in the United States. We aim to describe the epidemiology, trends, and costs of pediatric patients who present to US EDs with upper extremity injuries. Methods: Using the National Emergency Department Sample, we identified all ED encounters by patients aged <18 years associated with a primary diagnosis involving the upper extremity from 2008 to 2012. Patients were divided into 4 groups by age (≤5 years, 6-9 years, 10-13 years, and 14-17 years) and a trauma subgroup. Primary outcomes were prevalence, etiology, and associated charges. Results: In total, 11.7 million ED encounters were identified, and 89.8% had a primary diagnosis involving the upper extremity. Fracture was the most common injury type (28.2%). Dislocations were common in the youngest group (17.7%) but rare in the other 3 (range = 0.8%-1.6%). There were 73.2% of trauma-related visits, most commonly due to falls (29.9%); 96.9% of trauma patients were discharged home from the ED. There were bimodal peaks of incidence in the spring and fall and a nadir in the winter. Emergency department charges of $21.2 billion were generated during the 4 years studied. While volume of visits decreased during the study, associated charges rose by 1.21%. Conclusions: Pediatric upper extremity injuries place burden on the economy of the US health care system. Types of injuries and anticipated payers vary among age groups, and while total yearly visits have decreased over the study period, the average cost of visits has risen.

Initial Surgical Treatment for Breast Cancer and the Distance Traveled for Care.

BACKGROUND: Geography may influence the operative decision-making in breast cancer treatment. This study evaluates the relationship between distance to treating facility and the initial breast cancer surgery selected, identifying the characteristics of women who travel for surgery. METHODS: Utilizing Florida state inpatient and ambulatory surgery databases, we identified female breast cancer patients who underwent surgical treatment from January 1 to December 31, 2013. Patients were subgrouped by distance to treatment facility. The primary outcome was the initial surgical treatment choice. Regression models were used to identify factors associated with greater distance to initial treatment. RESULTS: The final sample included 12 786 patients who underwent lumpectomy, mastectomy alone, or mastectomy with reconstruction. Compared to women who traveled < 4.0 miles, women who traveled > 14.0 miles were younger (P < .001), more often identified as white with private insurance (P < .001) and were less likely to have three or more medical comorbidities (P < .001). With increased travel to treatment, the frequency of lumpectomy decreased (P < .001), while the frequency of mastectomy with reconstruction increased (P < .001). Increasing age in years (adjusted odds ratio (AOR) = .98 [95% CI = .98-.99]) and identifying as nonwhite with private (AOR = .70 [.61-.80]) or public insurance (AOR = .64 [.56-.73]) was associated with less frequently travelling for initial breast cancer surgery. DISCUSSION: The relationship between the initial surgical treatment for breast cancer and the distance traveled for care highlights a disparity between those who can and cannot travel for treatment.

Plastic Surgery at War: A Scoping Review of Current Conflicts.

INTRODUCTION: The scope of military plastic surgery and location where care is provided has evolved with each major conflict. To help inform plastic surgeon utilization in future conflicts, we conducted a review of military plastic surgery-related studies to characterize plastic surgeon contributions during recent military operations. MATERIALS AND METHODS: Using a scoping review design, we searched electronic databases to identify articles published since September 1, 2001 related to military plastic surgery according to a defined search criterion. Next, we screened all abstracts for appropriateness based on pre-established inclusion/exclusion criteria. Finally, we reviewed the remaining full-text articles to describe the nature of care provided and the operational level at which care was delivered. RESULTS: The final sample included 55 studies with most originating in the United States (54.5%) between 2005 and 2019 and were either retrospective cohort studies (81.8%) or case series (10.9%). The breadth of care included management of significant upper/lower extremity injuries (40%), general reconstructive and wound care (36.4%), and craniofacial surgery (16.4%). Microsurgical reconstruction was a primary focus in 40.0% of published articles. When specified, most care was described at Role 3 (25.5%) or Roles 4/5 facilities (62.8%) with temporizing measures more common at Role 3 and definite reconstruction at Roles 4/5. Several lessons learned were identified that held commonality across plastic surgery domain. CONCLUSIONS: Plastic surgeons continue to play a critical role in the management of wounded service members, particularly for complex extremity reconstruction, craniofacial trauma, and general expertise on wound management. Future efforts should evaluate mechanisms to maintain these skill sets among military plastic surgeons.

Cannabis Abuse or Dependence and Post-operative Outcomes After Appendectomy and Cholecystectomy.

BACKGROUND: Though cannabis is gaining broader acceptance among society and a noted increase in legalization, little is known regarding its impact on post-operative outcomes. We conducted this study to quantify the relationship between cannabis abuse or dependence (CbAD) on post-operative outcomes after cholecystectomy and appendectomy. METHODS: Using the 2013-2015 Nationwide Readmissions Database, we identified discharges associated with cholecystectomy or appendectomy from January 2013-August 2015. Patients were grouped by CbAD history. The primary outcomes were length of stay, serious adverse events, home discharge, and 30-day readmission. Propensity-score matching was used to account for differences between groups and all statistics accounted for the matched sample. RESULTS: The final sample included 3288 patients with a CbAD history matched 1:1 to patients without a CbAD history (total sample = 6576). After matching, acceptable balance was achieved in clinical characteristics between groups. In the cholecystectomy cohort (n = 1707 pairs), CbAD patients had longer hospitalizations (3.5 versus 3.2 d, P 0.003) and similar rates of serious adverse events (6.1 versus 4.8, P 0.092), home discharge (96.1 vs 96.2, P 0.855), and readmission (8.3 versus 6.9, P 0.137). In the appendectomy cohort (n = 1581 pairs), CbAD patients had longer hospital stays (2.7 versus 2.5 d, P 0.024); more frequent serious adverse events (5.0 versus 3.5, P 0.041); and similar home discharge (96.8 vs 97.3, P 0.404) and readmission (5.4 versus 5.1, P 0.639) rates. CONCLUSIONS: Patients with a history of CbAD in the cholecystectomy and appendectomy cohorts had slightly longer hospital stays, and patients with a history of CbAD in the appendectomy group displayed a slight increase in adverse events, but otherwise similar clinical outcomes without clinically significant increases in complications compared to patients without this history.

The Reducing Opioid Use in Children with Clefts Protocol: A Multidisciplinary Quality Improvement Effort to Reduce Perioperative Opioid Use in Patients Undergoing Cleft Surgery.

BACKGROUND: Cleft repair requires multiple operations from infancy through adolescence, with repeated exposure to opioids and their associated risks. The authors implemented a quality improvement project to reduce perioperative opioid exposure in their cleft lip/palate population. METHODS: After identifying key drivers of perioperative opioid administration, quality improvement interventions were developed to address these key drivers and reduce postoperative opioid administration from 0.30 mg/kg of morphine equivalents to 0.20 mg/kg of morphine equivalents. Data were retrospectively collected from January 1, 2015, until initiation of the quality improvement project (May 1, 2017), tracked over the 6-month quality improvement study period, and the subsequent 14 months. Metrics included morphine equivalents of opioids received during admission, administration of intraoperative nerve blocks, adherence to revised electronic medical record order sets, length of stay, and pain scores. RESULTS: The final sample included 624 patients. Before implementation (n =354), children received an average of 0.30 mg/kg of morphine equivalents postoperatively. After implementation (n = 270), children received an average of 0.14 mg/kg of morphine equivalents postoperatively (p < 0.001) without increased length of stay (28.3 versus 28.7 hours; p = 0.719) or pain at less than 6 hours (1.78 versus 1.74; p = 0.626) or more than 6 hours postoperatively (1.50 versus 1.49; p = 0.924). CONCLUSIONS: Perioperative opioid administration after cleft repair can be reduced in a relatively short period by identifying key drivers and addressing perioperative education, standardization of intraoperative pain control, and postoperative prioritization of nonopioid medications and nonpharmacologic pain control. The authors' quality improvement framework has promise for adaptation in future efforts to reduce opioid use in other surgical patient populations. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, III.

Added Healthcare Charges Conferred by Smoking in Outpatient Plastic Surgery.

BACKGROUND: A history of smoking confers additional risk of complications following plastic surgical procedures, which may require hospital-based care to address. OBJECTIVES: To determine if patients with a smoking history experience higher rates of complications leading to higher hospital-based care utilization, and therefore greater healthcare charges, after common outpatient plastic surgeries. METHODS: Using ambulatory surgery data from California, Florida, Nebraska, and New York, we identified adult patients who underwent common facial, breast, or abdominal contouring procedures from January 2009 to November 2013. Our primary outcomes were hospital-based, acute care (hospital admissions and emergency department visits), serious adverse events, and cumulative healthcare charges within 30 days of discharge. Multivariable regression models were used to compare outcomes between patients with and without a smoking history. RESULTS: The final sample included 214,761 patients, of which 10,426 (4.9%) had a smoking history. Compared to patients without, those with a smoking history were more likely to have a hospital-based, acute care encounter (3.4% vs 7.1%; AOR = 1.36 [1.25-1.48]) or serious adverse event (0.9% vs 2.2%; AOR = 1.38 [1.18-1.60]) within 30 days. On average, these events added $1826 per patient with a smoking history. These findings were consistent when stratified by specific procedure and controlled for patient factors. CONCLUSIONS: Patients undergoing common outpatient plastic surgery procedures who have a history of smoking are at risk for more frequent complications, and incur higher healthcare charges than patients who are nonsmokers.

Incisional Hernia in the United States: Trends in Hospital Encounters and Corresponding Healthcare Charges.

Incisional hernia (IH) is a challenging, potentially morbid condition. This study evaluates recent trends in hospital encounters associated with IH care in the United States. Using Nationwide Inpatient Sample databases from 2007 to 2011, annual estimates of IH-related hospital discharges, charges, and serious adverse events were identified. Significance in observed trends was tested using regression modeling. From 2007 to 2011, there were 583,054 hospital discharges associated with a diagnosis of IH. 81.1 per cent had a concurrent procedure for IH repair. The average discharge included a female patient (63.2%), 59.8 years of age, with either Medicare (45.3%) or Private insurance (38.3%) as the anticipated primary payer. Comparing 2007 to 2011, significant increases in IH discharges (12%; 2007 = 109,702 vs 2011 = 123,034, P = 0.009) and IH repairs (10%; 2007 = 90,588 vs 2011 = 99,622, P < 0.001) were observed. This was accompanied by a 37 per cent increase in hospital charges (2007 = $44,587 vs 2011 = $60,968, P < 0.001), resulting in a total healthcare bill of $7.3 billion in 2011. Significant trends toward greater patient age (2007 = 59.7 years vs 2011 = 60.2 years, P < 0.001), higher comorbidity index (2007 = 3.0 vs 2011 = 3.5, P < 0.001), and increased frequency of serious adverse events (2007 = 13.5% vs 2011 = 17.7%, P < 0.001) were noted. Further work is needed to identify interventions to mitigate the risk of IH development.

Hospitalization Rates for Acute Myocardial Infarction Among Asian-American Subgroups: Have We Been Underestimating the Problem?

Concerns about the quality of race/ethnicity data collected by hospitals have limited our understanding of healthcare disparities affecting ethnic minorities in the United States. Using data from the New Jersey State Inpatient Databases and the American Community Survey, we calculated age-adjusted AMI hospitalization rates for Asian-American subgroups before (2005-2006) and after (2008-2009) New Jersey hospitals implemented standardized practices to collect more accurate granular race/ethnicity data from patients. Rates were reported per 100,000 persons for Asian Indian, Chinese, Filipino, Japanese, Korean, and Vietnamese subgroups. AMI hospitalization rates increased for all subgroups except Vietnamese following implementation of the New Jersey program; increases were statistically significant for Asian Indian, Chinese, and Korean subgroups. Rates of hospitalization for AMI increased significantly for multiple Asian-American subgroups following implementation of the New Jersey program. National population health metrics for Asian-American subgroups may be prone to significant underestimation without widespread utilization of similar practices.

Burden of Hand Maladies in US Emergency Departments.

BACKGROUND: Hand conditions commonly present to the emergency department (ED), yet data are lacking regarding the magnitude of hand-related conditions in the emergency setting. The purpose of this study is to describe the burden and quantify the health care resource utilization of hand conditions seen in EDs across the United States. METHODS: Using the National Emergency Department Sample, we identified all ED encounters by patients at least 18 years of age that were associated with a hand condition in 2009 to 2012. The primary outcomes were prevalence, etiology, and associated health care charges for specific categories of hand conditions. RESULTS: The final sample included 34.4 million ED encounters associated with a common hand condition generating $180.4 billion in health care charges. The volume of hand-related presentations varied in a predictable and cyclical manner, peaking in July and waning in December of each year. Trauma was the most common etiology (77.5%) predominantly due to falls (26.2%) and lacerations (19.7%). Over 4 years, the volume of ED encounters rose (5% increase, P < .001) and as did the resulting health care charges (24.6% increase, P < .001). CONCLUSIONS: Our study confirms that hand-related conditions contribute significantly to ED volume and consume a growing quantity of health care resources in the United States. The volume of patients presenting to EDs with hand-related conditions fluctuates cyclically throughout the year. Open wounds are the most common cause of presentation and mostly occur in young adults, followed by joint pain, contusions, and fractures.

Influence of race, insurance status, and geographic access to plastic surgeons on immediate breast reconstruction rates.

BACKGROUND: This study evaluates the rates of immediate breast reconstruction (IBR) among racial and insurance status subgroups, in the setting of a changing plastic surgeon workforce. METHODS: Using state level inpatient and ambulatory surgery data, we identified discharges for adult women who underwent mastectomy for breast cancer. This information was supplemented with plastic surgeon workforce data and aggregated to the health service area-level (HSA). Hierarchical linear models were used to risk standardized IBR rates for 8 race-payer subgroups. RESULTS: The final cohort included 65,246 women treated across 67 HSAs. The plastic surgeon density per 100,000 population directly related to the IBR rate. While all subgroups saw a modest increase in IBR rates, Caucasian women with private insurance realized the largest absolute increase (46%) while African-American and Asian women with public insurance saw the smallest increase (6%). CONCLUSION: Significant disparities persist in the provision of IBR according to the form of insurance a patient possesses. Of heightened concern is the novel finding that even within privately insured patients, women of color have significantly lower IBR rates compared to Caucasian women.

Venous Thromboembolism After Surgical Treatment of Breast Cancer.

BACKGROUND: Venous thromboembolism (VTE) remains a serious complication after the surgical treatment of breast cancer. Contemporary guidelines limit VTE chemoprophylaxis to the period of hospitalization. We conducted this study to evaluate the frequency of postdischarge VTE among surgically treated breast cancer patients and identify patient level factors associated with postdischarge VTE. METHODS: Using Arkansas, Florida, Nebraska, and New York state inpatient databases, we conducted a retrospective cohort study of adult women who underwent surgical treatment for breast cancer between October 1, 2008, and September 30, 2013. The primary outcome was a VTE event within 90 days of discharge. Multivariable logistic regression modeling was used to identify patient factors associated with VTE development. RESULTS: The final sample included 52,547 women with most undergoing mastectomy without reconstruction (n = 25,665), followed by mastectomy with implant based reconstruction (n = 16,851), lumpectomy (n = 5319), and mastectomy with autologous reconstruction (n = 4622). There were 395 patients (0.8%) who developed at least 1 VTE. Of the 395 VTEs, 32.9% (n = 130) were identified before discharge, whereas 67.1% were identified within 90 days after discharge. Patients with respiratory disease (adjusted odds ratio [AOR] = 1.56 [1.22-1.98]), hypothyroidism (AOR = 1.31 [1.01-1.70]), a hospital stay of more than 5 days (AOR = 8.07 [5.99-10.89]), previous VTE (AOR = 6.26 [3.95-9.91]), or mastectomy with autologous reconstruction (AOR = 1.50 [1.03-2.19]) more frequently developed postdischarge VTEs. CONCLUSIONS: Nearly two thirds of all 90-day VTE events after breast cancer surgery occur after discharge. Further research should determine whether a longer course of VTE prophylaxis is warranted among specific populations including those with prolonged hospitalizations, previous VTE, and those undergoing autologous reconstruction.

Development of a Clinically Actionable Incisional Hernia Risk Model after Colectomy Using the Healthcare Cost and Utilization Project.

BACKGROUND: Incisional hernia remains a persistent and burdensome complication after colectomy. Through individualized risk-assessment and prediction models, we aimed to improve preoperative risk counseling for patients undergoing colectomy; identify modifiable preoperative risk factors; and encourage the use of evidence-based risk-prediction instruments in the clinical setting. STUDY DESIGN: A retrospective review of the Healthcare Cost and Utilization Project data was conducted for all patients undergoing either open or laparoscopic colectomy as identified through the state inpatient databases of California, Florida, and New York in 2009. Incidence of incisional hernia repair was collected from both the state inpatient databases and the state ambulatory surgery and services databases in the 3 states between index surgery and 2011. Hernia risk was calculated with multivariable hierarchical logistic regression modeling and validated using bootstrapping techniques. Exclusion criteria included concurrent hernia, metastasis, mortality, and age younger than 18 years. Inflation-adjusted expenditure estimates were calculated. RESULTS: Overall, 30,741 patients underwent colectomy, one-third of these procedures performed laparoscopically. Incisional hernia repair was performed in 2,563 patients (8.3%) (27-month follow-up). Fourteen significant risk factors were identified, including open surgery (odds ratio = 1.49; p < 0.0001), obesity (odds ratio = 1.49; p < 0.0001), and alcohol abuse (odds ratio = 1.39; p = 0.010). Extreme-risk patients experienced the highest incidence of incisional hernia (19.8%) vs low-risk patients (3.9%) (C-statistic = 0.67). CONCLUSIONS: We present a clinically actionable model of incisional hernia using all-payer claims after colectomy. The data presented can structure preoperative risk counseling, identify modifiable patient-specific risk factors, and advance the field of risk prediction using claims data.

Concurrent panniculectomy in the obese ventral hernia patient: Assessment of short-term complications, hernia recurrence, and healthcare utilization.

BACKGROUND: Panniculectomy (PAN) is often performed concurrently with ventral hernia repair (VHR) in the obese patient. However, the effectiveness and safety profile of this common practice are not fully established in part because of paucity of comparative effectiveness studies. In this study, a comparative analysis of early complications, long-term hernia recurrence, and healthcare expenditures between VHR-PAN and VHR-only patients is presented. METHODS: From the Healthcare Cost and Utilization Project database, obese patients who underwent VHR with and without concurrent PAN were identified. Multivariate cox proportional-hazards regression modeling was performed to compare outcomes between the two groups. RESULTS: The final cohort included 1013 VHR-PAN and 18,328 VHR-only patients. The VHR-PAN patients experienced a longer adjusted length of hospital stay (6.8 days vs. 5.2 days; p < 0.001), a higher rate of in-hospital adverse events (29.3% vs. 20.7%; AOR = 2.34 [2.01-2.74]), and a higher rate of 30-day readmissions (13.6% vs. 8.1%; AOR = 2.04 [1.69-2.48]). However, the 2-year rate of hernia recurrence was lower in the VHR-PAN group (7.9% vs. 11.3%; AOR = 0.65 [0.51-0.82]). Both groups generated considerable hospital charges ($104,805 VHR-PAN vs. $72,206 VHR-only, p < 0.001). CONCLUSION: Performing a concurrent PAN in the obese hernia patient is associated with a higher rate of early complications and greater healthcare expenditures, but overall a substantially lower incidence of 2-year hernia recurrence. The literature review presented here also highlights a substantial need for further comparative effectiveness studies to create the needed framework for evidence-based guidelines.

Trends in open abdominal surgery in the United States-Observations from 9,950,759 discharges using the 2009-2013 National Inpatient Sample (NIS) datasets.

INTRODUCTION: Incisional hernia (IH) represents a complex and costly surgical complication. We aim to address trends in open surgery to better understand potential drivers of hernia risk. MATERIAL AND METHODS: Using the 2009-2013 NIS, a cross-sectional review of hospital discharges associated with an open abdominal surgery was performed. RESULTS: Between 2009 and 2013, there were nearly 10 million discharges associated with an open abdominal surgery. Overall, there were 2,140,616 patients receiving open surgery in 2009, decreasing to 1,760,549 in 2013 (18% decrease, p < 0.001). Open hernia procedures increased from 37,325 patients in 2009 to 41,845 in 2013 (12% increase, p = 0.001). The most prevalent comorbidities within this population included uncomplicated hypertension (25.26%), chronic pulmonary diseases (13.52%), obesity (10.24%), uncomplicated diabetes (11.06%), and depression (10.72%). CONCLUSIONS: Our analysis allowed for a unique view of surgical trends, health care population dynamics, and an opportunity to use evidence-driven analytics in the understanding of IH.
