Geographic Proximity of Family Members and Healthcare Utilization After Complex Surgical Procedures.

OBJECTIVE: We sought to determine the relationship between a patient's proximal familial social support, defined as the geographic proximity of family members, and healthcare utilization after complex cardiovascular and oncologic procedures. BACKGROUND: Social support mechanisms are increasingly identified as modifiable risk factors for healthcare utilization. METHODS: We performed a retrospective cohort study of 60,895 patients undergoing complex cardiovascular procedures or oncologic procedures. We defined healthcare utilization outcomes as 30-day all-cause readmission unplanned readmission, nonindex hospital readmission, index hospital length of stay, and home discharge disposition. For each patient, we aggregated the number of first-degree relatives (FDR) living within 30 miles of the patient's home address at the time of the surgical procedure into the following categories: 0 to 1, 2 to 3, 4 to 5, 6+ FDRs. We developed hierarchical multivariable regression models to determine the relationship between the number of FDR living within 30 miles of the patient and the healthcare utilization outcomes. RESULTS: Compared with patients with 0 to 1 FDRs, patients with 6+ FDRs living in close proximity had significantly lower rates of all-cause readmission (12.1% vs 13.5%, P <0.001), unplanned readmission (10.9% vs 12.0%, P =0.001), nonindex readmission (2.6% vs 3.2%, P =0.003); higher rates of home discharge (88.0% vs 85.3%, P <0.001); and shorter length of stay (7.3 vs 7.5 days, P =0.02). After multivariable adjustment, a larger number of FDRs living within 30 miles of the patient was significantly associated with a lower likelihood of all-cause readmission ( P <0.001 for trend), 30-day unplanned readmission ( P <0.001), nonindex readmission ( P <0.001); higher likelihood of home discharge ( P <0.001); and shorter index length of stay ( P <0.001). CONCLUSIONS: The geographic proximity of family members is significantly associated with decreased healthcare utilization after complex cardiovascular and oncologic surgical procedures.

Hospital Costs Following Surgical Complications: A Value-driven Outcomes Analysis of Cost Savings Due to Complication Prevention.

OBJECTIVE: Surgical complications have substantial impact on healthcare costs. We propose an analysis of the financial impact of postoperative complications. SUMMARY OF BACKGROUND DATA: Both complications and preoperative patient risk have been shown to increase costs following surgery. The extent of cost increase due to specific complications has not been well described. METHODS: A single institution's American College of Surgeons National Surgical Quality Improvement Program data was queried from 2012 to 2018 and merged with institutional cost data for each encounter. A mixed effects multivariable generalized linear model was used to estimate the mean relative increase in hospital cost due to each complication, adjusting for patient and procedure-level fixed effects clustered by procedure. Potential savings were calculated based on projected decreases in complication rates and theoretical hospital volume. RESULTS: There were 11,897 patients linked between the 2 databases. The rate of any American College of Surgeons National Surgical Quality Improvement Program complication was 11.7%. The occurrence of any complication resulted in a 1.5-fold mean increase in direct hospital cost [95% confidence interval (CI) 1.49-1.58]. The top 6 most costly complications were postoperative septic shock (4.0-fold, 95% CI 3.58-4.43) renal insufficiency/failure (3.3-fold, 95% CI 2.91-3.65), any respiratory complication (3.1-fold, 95% CI 2.94-3.36), cardiac arrest (3.0-fold, 95% CI 2.64-3.46), myocardial infarction (2.9-fold, 95% CI 2.43-3.42) and mortality within 30 days (2.2-fold, 95% CI 2.01-2.48). Length of stay (6.5 versus 3.2 days, P < 0.01), readmission rate (29.1% vs 3.1%, P < 0.01), and discharge destination outside of home (20.5% vs 2.7%, P < 0.01) were significantly higher in the population who experienced complications. CONCLUSIONS: Decreasing complication rates through preoperative optimization will improve patient outcomes and lead to substantial cost savings.

Comparison of Patient Outcomes Among Integrated Residency Versus Fellowship-trained Vascular Surgeons.

OBJECTIVE: This study aims to evaluate whether graduates of integrated vascular surgery residency (IVSR) programs achieve similar surgical outcomes in clinical practice as compared to graduates of vascular surgery fellowships (VSF). SUMMARY OF BACKGROUND DATA: Early sub-specialization through IVSR programs decreases the total years of surgical training. However, it is unclear whether IVSR graduates achieve comparable outcomes to fellowship-trained surgeons once in clinical practice. METHODS: We identified all vascular surgeons who finished IVSR and VSF programs between 2013-2017 using American Board of Surgery data, which was linked to the Vascular Quality Initiative registry (2013-2019) to evaluate provider-specific clinical outcomes following carotid, lower extremity, and aortic aneurysm repair procedures. The association between training models and the composite outcome of 1-year mortality, major adverse cardiac events and/or other major complications were analyzed using mixed-effects logistic regression models. RESULTS: A total of 338 surgeons (31% IVSR, 69% VSF) submitted cases into the Vascular Quality Initiative registry, including 8155 carotid, 21,428 lower extremity, and 5800 aortic aneurysm repair procedures. Composite 1-year outcome rates were comparable between IVSR and VSF-trained surgeons following carotid endarterectomy (8%-IVSR vs 7%-VSF), lower extremity revascularization (19%-IVSR vs 16%-VSF), and aortic aneurysm repair (13%-IVSR vs 13%-VSF) procedures. These findings among IVSR-trained surgeons persisted following risk adjustment for severity of patient disease and indications for undertaking carotid [aOR: 1.04 (0.84-1.28)], lower extremity [aOR: 1.03 (0.84-1.26)], and aortic [aOR: 0.96 (0.76-1.21)] procedures when compared to VSF-trained surgeons. CONCLUSIONS: Despite fewer total years of training, graduates of IVSR programs achieve equivalent surgical outcomes as fellowship-trained vascular surgeons once in practice. These results suggest that concerns about differential competence among integrated residency graduates are not warranted.

Value Analysis of Methods of Inguinal Hernia Repair.

OBJECTIVE: Value is defined as health outcomes important to patients relative to cost of achieving those outcomes: Value = Quality/Cost. For inguinal hernia repair, Level 1 evidence shows no differences in long-term functional status or recurrence rates when comparing surgical approaches. Differences in value reside within differences in cost. The aim of this study is to compare the value of different surgical approaches to inguinal hernia repair: Open (Open-IH), Laparoscopic (Lap-IH), and Robotic (R-TAPP). METHODS: Variable and fixed hospital costs were compared among consecutive Open-IH, Lap-IH, and R-TAPP repairs (100 each) performed in a university hospital. Variable costs (VC) including direct materials, labor, and variable overhead ($/min operating room [OR] time) were evaluated using Value Driven Outcomes, an internal activity-based costing methodology. Variable and fixed costs were allocated using full absorption costing to evaluate the impact of surgical approach on value. As cost data is proprietary, differences in cost were normalized to Open-IH cost. RESULTS: Compared to Open-IH, VC for Lap-IH were 1.02X higher (including a 0.81X reduction in cost for operating room [OR] time). For R-TAPP, VC were 2.11X higher (including 1.36X increased costs for OR time). With allocation of fixed cost, a Lap-IH was 1.03X more costly, whereas R-TAPP was 3.18X more costly than Open-IH. Using equivalent recurrence as the quality metric in the value equation, Lap-IH decreases value by 3% and R-TAPP by 69% compared to Open-IH. CONCLUSIONS: Use of higher cost technology to repair inguinal hernias reduces value. Incremental health benefits must be realized to justify increased costs. We expect payors and patients will incorporate value into payment decisions.

Natural language processing for the surveillance of postoperative venous thromboembolism.

BACKGROUND: The objective of this study was to develop a portal natural language processing approach to aid in the identification of postoperative venous thromboembolism events from free-text clinical notes. METHODS: We abstracted clinical notes from 25,494 operative events from 2 independent health care systems. A venous thromboembolism detected as part of the American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) was used as the reference standard. A natural language processing engine, easy clinical information extractor-pulmonary embolism/deep vein thrombosis (EasyCIE-PEDVT), was trained to detect pulmonary embolism and deep vein thrombosis from clinical notes. International Classification of Diseases (ICD) discharge diagnosis codes for venous thromboembolism were used as baseline comparators. The classification performance of EasyCIE-PEDVT was compared with International Classification of Diseases codes using sensitivity, specificity, area under the receiver operating characteristic curve, using an internal and external validation cohort. RESULTS: To detect pulmonary embolism, EasyCIE-PEDVT had a sensitivity of 0.714 and 0.815 in internal and external validation, respectively. To detect deep vein thrombosis, EasyCIE-PEDVT had a sensitivity of 0.846 and 0.849 in internal and external validation, respectively. EasyCIE-PEDVT had significantly higher discrimination for deep vein thrombosis compared with International Classification of Diseases codes in internal validation (area under the receiver operating characteristic curve: 0.920 vs 0.761; P < .001) and external validation (area under the receiver operating characteristic curve: 0.921 vs 0.794; P < .001). There was no significant difference in the discrimination for pulmonary embolism between EasyCIE-PEDVT and ICD codes. CONCLUSION: Accurate surveillance of postoperative venous thromboembolism may be achieved using natural language processing on clinical notes in 2 independent health care systems. These findings suggest natural language processing may augment manual chart abstraction for large registries such as NSQIP.

Portable Automated Surveillance of Surgical Site Infections Using Natural Language Processing: Development and Validation.

OBJECTIVES: We present the development and validation of a portable NLP approach for automated surveillance of SSIs. SUMMARY OF BACKGROUND DATA: The surveillance of SSIs is labor-intensive limiting the generalizability and scalability of surgical quality surveillance programs. METHODS: We abstracted patient clinical text notes after surgical procedures from 2 independent healthcare systems using different electronic healthcare records. An SSI detected as part of the American College of Surgeons' National Surgical Quality Improvement Program was used as the reference standard. We developed a rules-based NLP system (Easy Clinical Information Extractor [CIE]-SSI) for operative event-level detection of SSIs using an training cohort (4574 operative events) from 1 healthcare system and then conducted internal validation on a blind cohort from the same healthcare system (1850 operative events) and external validation on a blind cohort from the second healthcare system (15,360 operative events). EasyCIE-SSI performance was measured using sensitivity, specificity, and area under the receiver-operating-curve (AUC). RESULTS: The prevalence of SSI was 4% and 5% in the internal and external validation corpora. In internal validation, EasyCIE-SSI had a sensitivity, specificity, AUC of 94%, 88%, 0.912 for the detection of SSI, respectively. In external validation, EasyCIE-SSI had sensitivity, specificity, AUC of 79%, 92%, 0.852 for the detection of SSI, respectively. The sensitivity of EasyCIE-SSI decreased in clean, skin/subcutaneous, and outpatient procedures in the external validation compared to internal validation. CONCLUSION: Automated surveillance of SSIs can be achieved using NLP of clinical notes with high sensitivity and specificity.

Measuring the migration of surgical specialists.

BACKGROUND: The lack of access to essential surgical care in low-income countries is aggravated by emigration of locally-trained surgical specialists to more affluent regions. Yet, the global diaspora of surgeons, obstetricians, and anesthesiologists from low-income and middle-income countries has never been fully described and compared with those who have remained in their country of origin. It is also unclear whether the surgical workforce is more affected by international migration than other medical specialists. In this study, we aimed to quantify the proportion of surgical specialists originating from low-income and middle-income countries that currently work in high-income countries. METHODS: We retrieved surgical workforce data from 48 high-income countries and 102 low-income and middle-income countries using the database of the World Health Organization Global Surgical Workforce. We then compared this domestic workforce with more granular data on the country of initial medical qualification of all surgeons, anesthesiologists, and obstetricians made available for 14 selected high-income countries to calculate the proportion of surgical specialists working abroad. RESULTS: We identified 1,118,804 specialist surgeons, anesthesiologists, or obstetricians from 102 low-income and middle-income countries, of whom 33,021 (3.0%) worked in the 14 included high-income countries. The proportion of surgical specialists abroad was greatest for the African and South East Asian regions (12.8% and 12.1%). The proportion of specialists abroad was not greater for surgeons, anesthesiologists, or obstetricians than for physicians and other medical specialists (P = .465). Overall, the countries with the lowest remaining density of surgical specialists were also the countries from which the largest proportion of graduates were now working in high-income countries (P = .011). CONCLUSION: A substantial proportion of all surgeons, anesthesiologists, and obstetricians from low-income and middle-income countries currently work in high-income countries. In addition to decreasing migration from areas of surgical need, innovative strategies to retain and strengthen the surgical workforce could involve engaging this large international pool of surgical specialists and instructors.

Home Disposal Kits for Leftover Opioid Medications After Surgery: Do They Work?

BACKGROUND: Postoperative overprescribing is common, and many patients will have excess medications. An effective method to encourage disposal is lacking. We hypothesized that a convenient home disposal kit will result in more appropriate disposal of excess opioids. MATERIALS AND METHODS: We conducted a single-center prospective observational pilot study to evaluate the effectiveness of a postoperative opioid disposal kit. Patients in the intervention group received an opioid disposal kit and educational handout before discharge from the hospital. At the first follow-up visit, patients completed a survey in which they reported the remaining amount of pain medications from their original prescription and their plan for the excess medication. Patients were asked about risk factors for chronic opioid use. We used multivariable Poisson regression to identify independent factors associated with an increased likelihood of appropriate opioid disposal. RESULTS: The survey was offered to 904 patients with a response rate of 91.7%. After excluding those with missing data, 571 patients were included in the study. Overall, 83 (14.5%) patients never filled an opioid prescription, and 286 (60.0%) patients had tablets remaining at the time of the follow-up visit. Among those with tablets remaining, 52 received a home disposal kit, whereas 234 patients with tablets remaining did not. Patients who received the kit were more likely to dispose of opioid medications (54.9% versus 34.8%, relative risk = 1.8, 95% CI 1.3-2.5). No confounders were identified during multivariable analysis that increased a patient's likelihood of disposing excess medications. CONCLUSIONS: The provision of a convenient home disposal kit postoperatively increased patient-reported opioid disposal.

Patient Satisfaction With Decision Making Does Not Correlate With Patient Centeredness of Surgeons.

BACKGROUND: High-quality decision making is important in patient-centered care. Although patient involvement in decision making varies widely, most patients desire to share in decision making. The Press-Ganey Patient Satisfaction survey includes questions that measure patients' perceptions of their providers' efforts to involve them in decision making (PGDM). We hypothesized that higher PGDM scores would correlate with higher scores on a validated measure of patient centeredness. MATERIALS AND METHODS: Surgical providers at a university hospital who routinely receive Press-Ganey scores received a survey that included the Patient-Practitioner Orientation Scale (PPOS), a validated tool that measures the provider's orientation toward patient centeredness on a continuous six-point scale: score ≥5 = high, 4.57-5 = moderate, and <4.57 = low and includes nine-item "caring" or "sharing" subscales. We compared PPOS scores to PGDM scores, averaged from April 2015 to January 2016. RESULTS: Eighty-six of 112 (75%) of surgical providers responded to the survey. Fifty-two (46%) had PGDM scores available and 26% achieved a perfect score on the PGDM. The overall PPOS scores were low, with a mean of 4.2 (SD = 0.5). The PPOS was not correlated with the PGDM, correlation coefficient (rs) = -0.07 (CI: -0.34-0.21, P = 0.63). Similarly, the two subscales of the PPOS did not correlate with the PGDM with rs = -0.15 (CI: -0.41-0.13, P = 0.29) for "caring" and rs = -0.04 (CI: -0.31-0.23, P = 0.76) for "sharing". CONCLUSIONS: Although surgical providers scored low in patient centeredness using the PPOS, over one-quarter (26%) of them rank in the top 1% on the PGDM. No correlation was found between providers' patient centeredness and their patients' perceptions of efforts to include them in decision making.

Hospital-level Variation in Utilization of Surgery for Clinical Stage I-II Pancreatic Adenocarcinoma.

OBJECTIVE: To (1) evaluate rates of surgery for clinical stage I-II pancreatic ductal adenocarcinoma (PDAC), (2) identify predictors of not undergoing surgery, (3) quantify the degree to which patient- and hospital-level factors explain differences in hospital surgery rates, and (4) evaluate the association between adjusted hospital-specific surgery rates and overall survival (OS) of patients treated at different hospitals. BACKGROUND: Curative-intent surgery for potentially resectable PDAC is underutilized in the United States. METHODS: Retrospective cohort study of patients ≤85 years with clinical stage I-II PDAC in the 2004 to 2014 National Cancer Database. Mixed effects multivariable models were used to characterize hospital-level variation across quintiles of hospital surgery rates. Multivariable Cox proportional hazards models were used to estimate the effect of adjusted hospital surgery rates on OS. RESULTS: Of 58,553 patients without contraindications or refusal of surgery, 63.8% underwent surgery, and the rate decreased from 2299/3528 (65.2%) in 2004 to 4412/7092 (62.2%) in 2014 (P < 0.001). Adjusted hospital rates of surgery varied 6-fold (11.4%-70.9%). Patients treated at hospitals with higher rates of surgery had better unadjusted OS (median OS 10.2, 13.3, 14.2, 16.5, and 18.4 months in quintiles 1-5, respectively, P < 0.001, log-rank). Treatment at hospitals in lower surgery rate quintiles 1-3 was independently associated with mortality [Hazard ratio (HR) 1.10 (1.01, 1.21), HR 1.08 (1.02, 1.15), and HR 1.09 (1.04, 1.14) for quintiles 1-3, respectively, compared with quintile 5] after adjusting for patient factors, hospital type, and hospital volume. CONCLUSIONS: Quality improvement efforts are needed to help hospitals with low rates of surgery ensure that their patients have access to appropriate surgery.

Use of Computerized Provider Order Entry Events for Postoperative Complication Surveillance.

Importance: Conventional approaches for tracking postoperative adverse events requires manual medical record review, thus limiting the scalability of such efforts. Objective: To determine if a surveillance system using computerized provider order entry (CPOE) events for selected medications as well as laboratory, microbiologic, and radiologic orders can decrease the manual medical record review burden for surveillance of postoperative complications. Design, Setting, and Participants: This cohort study reviewed the medical records of 21 775 patients who underwent surgical procedures at a university-based tertiary referral center (University of Utah, Salt Lake City) from July 1, 2007, to August 31, 2017. Patients were included if their case was selected for review by a surgical clinical reviewer as part of the National Surgical Quality Improvement Program. Patients were excluded if they had incomplete follow-up data. Main Outcomes and Measures: Thirty-day postoperative occurrences of superficial surgical site infection, deep surgical site infection, organ space surgical site infection, urinary tract infection, pneumonia, sepsis, septic shock, deep vein thrombosis requiring therapy, and pulmonary embolism, as defined by the National Surgical Quality Improvement Program. A logistic regression model was developed for each postoperative complication using CPOE features as predictors on a development set, and performance was measured on a holdout internal validation set. The models were internally validated using bootstrapping with 10 000 replications to determine the sensitivity, specificity, positive predictive value, and negative predictive value of CPOE-based surveillance system. Results: The study included 21 775 patients who underwent surgical procedures. Among these patients, 11 855 (54.4%) were women and 9920 (45.6%) were men, with a mean (SD) age of 51.7 (16.8) years. Overall, the prevalence of postoperative complications was low, ranging from 0.2% (pulmonary embolism) to 2.6% (superficial surgical site infection). Use of CPOE events to detect patients who experienced at least 1 complication had a sensitivity of 74.8% (95% CI, 71.1%-78.4%), specificity of 86.8% (95% CI, 85.5%-88.3%), positive predictive value of 33.8% (95% CI, 31.2%-36.4%), negative predictive value of 97.5% (95% CI, 97.1%-97.8%), and area under the curve of 0.808 (95% CI, 0.791-0.824). The negative predictive value for individual complications ranged from 98.7% to 100%. Use of CPOE events to screen for adverse events was estimated to diminish the burden of manual medical record review by 55.4% to 90.3%. A CPOE-based surveillance system performed well for both inpatient and outpatient procedures. Conclusions and Relevance: A CPOE-based surveillance of postoperative complications has high negative predictive value, which demonstrates that this approach can augment the currently used, resource-intensive manual medical record review process.

Precision-Exercise-Prescription in patients with lung cancer undergoing surgery: rationale and design of the PEP study trial.

INTRODUCTION: Lung cancer is a significant burden on societies worldwide, and the most common cause of death in patients with cancer overall. Exercise intervention studies in patients with lung cancer have consistently shown benefits with respect to physical and emotional functioning. However, to date, exercise training has not been consistently implemented into clinical practice given that interventions have been costly and not aligned with clinical care. METHODS/DESIGN: The Precision-Exercise-Prescription (PEP) study is a prospective randomised controlled trial comparing the effectiveness and feasibility of a personalised intervention exercise programme among patients with lung cancer undergoing surgery. Two-hundred patients who are diagnosed with stage primary or secondary lung cancer and are eligible to undergo surgical treatment at Huntsman Cancer Institute comprise the target population. Patients are randomised to either the (1) outpatient precision-exercise intervention group or (2) delayed intervention group. The intervention approach uses Motivation and Problem Solving, a hybrid behavioural treatment based on motivational interviewing and practical problem solving. The dosage of the exercise intervention is personalised based on the individual's Activity Measure for Post-Acute-Care outpatient basic mobility score, and incorporates four exercise modes: mobility, callisthenics, aerobic and resistance. Exercise is implemented by physical therapists at study visits from presurgery until 6 months postsurgery. The primary endpoint is the level of physical function assessed by 6 min walk distance at 2 months postsurgery. Secondary outcomes include patient-reported outcomes (eg, quality of life, fatigue and self-efficacy) and other clinical outcomes, including length of stay, complications, readmission, pulmonary function and treatment-related costs up to 6 months postsurgery. ETHICS/DISSEMINATION: The PEP study will test the clinical effectiveness and feasibility of a personalised exercise intervention in patients with lung cancer undergoing surgery. Outcomes of this clinical trial will be presented at national and international conferences and symposia and will be published in international, peer-reviewed journals. Ethics approval was obtained at the University of Utah (IRB 00104671). TRIAL REGISTRATION NUMBER: NCT03306992.

Guide to research in academic global surgery: A statement of the Society of University Surgeons Global Academic Surgery Committee.

Global surgery is an emerging academic discipline that is developing in tandem with numerous policy and advocacy initiatives. In this regard, academic global surgery will be crucial for measuring the progress toward improving surgical care worldwide. However, as a nascent academic discipline, there must be rigorous standards for the quality of work that emerges from this field. In this white paper, which reflects the opinion of the Global Academic Surgery Committee of the Society for University Surgeons, we discuss the importance of research in global surgery, the methodologies that can be used in such research, and the challenges and benefits associated with carrying out this research. In each of these topics, we draw on existing examples from the literature to demonstrate our points. We conclude with a call for continued, high-quality research that will strengthen the discipline's academic standing and help us move toward improved access to and quality of surgical care worldwide.

An International Collaborative Standardizing a Comprehensive Patient-Centered Outcomes Measurement Set for Colorectal Cancer.

IMPORTANCE: Global health systems are shifting toward value-based care in an effort to drive better outcomes in the setting of rising health care costs. This shift requires a common definition of value, starting with the outcomes that matter most to patients. OBJECTIVE: The International Consortium for Health Outcomes Measurement (ICHOM), a nonprofit initiative, was formed to define standard sets of outcomes by medical condition. In this article, we report the efforts of ICHOM's working group in colorectal cancer. EVIDENCE REVIEW: The working group was composed of multidisciplinary oncology specialists in medicine, surgery, radiation therapy, palliative care, nursing, and pathology, along with patient representatives. Through a modified Delphi process during 8 months (July 8, 2015 to February 29, 2016), ICHOM led the working group to a consensus on a final recommended standard set. The process was supported by a systematic PubMed literature review (1042 randomized clinical trials and guidelines from June 3, 2005, to June 3, 2015), a patient focus group (11 patients with early and metastatic colorectal cancer convened during a teleconference in August 2015), and a patient validation survey (among 276 patients with and survivors of colorectal cancer between October 15, 2015, and November 4, 2015). FINDINGS: After consolidating findings of the literature review and focus group meeting, a list of 40 outcomes was presented to the WG and underwent voting. The final recommendation includes outcomes in the following categories: survival and disease control, disutility of care, degree of health, and quality of death. Selected case-mix factors were recommended to be collected at baseline to facilitate comparison of results across treatments and health care professionals. CONCLUSIONS: A standardized set of patient-centered outcome measures to inform value-based health care in colorectal cancer was developed. Pilot efforts are under way to measure the standard set among members of the working group.

Indications for Adjuvant Mediastinal Radiotherapy in Surgically Resected Small Cell Lung Cancer.

BACKGROUND: Adjuvant mediastinal radiotherapy (AMR) is used after surgical resection for patients with small cell lung cancer (SCLC), but data guiding its use are scant. We sought to examine whether AMR was associated with an improvement in survival for resected SCLC patients and to define subpopulations who should be selected for AMR. METHODS: Patients undergoing lobectomy, pneumonectomy, and sublobar resection for SCLC were identified in the National Cancer Database (2004 to 2013). Kaplan-Meier survival curves and Cox proportional hazards were used to evaluate associations between AMR and survival. Hazard ratios were adjusted for patient comorbidity, demographics, tumor characteristics, such as stage, grade, histology, and margin status, and receipt of adjuvant chemotherapy. RESULTS: We identified 3,101 patients. Those receiving AMR were younger, more likely to have greater pathologic T and N stage, to undergo sublobar resection, and to have a positive margin. Kaplan-Meier curves showed better median survival for patients with pN1 or pN2 disease who received AMR. After adjustment, Cox models showed AMR was associated with a lower risk of death for pN1 (hazard ratio, 0.79; 95% confidence interval, 0.63 to 1.00; p = 0.05) and pN2 (hazard ratio, 0.60; 95% confidence interval, 0.48 to 0.75; p < 0.0001). In the overall cohort, AMR was not associated with better survival in node-negative patients. AMR was, however, associated with improved survival for patients receiving sublobar resection (hazard ratio, 0.72; 95% confidence interval, 0.57 to 0.90; p = 0.004). CONCLUSIONS: AMR is associated with longer survival for node-positive patients after resection for SCLC, especially those with pN2. AMR may also be associated with longer survival in patients undergoing sublobar resections.

Patient Preparation for Transitions of Surgical Care: Is Failing to Prepare Surgical Patients Preparing Them to Fail?

BACKGROUND: Transitions of care before and after surgery are critical for patient preparation. We sought to determine whether the degree of exposure to health information resources before and after surgery increases preparedness and decreases hospital readmission. METHODS: A national Web-based, cross-sectional survey was conducted of 1917 patients and caregivers who had a recent surgical encounter. Health information resources used before and after surgery were correlated with patient level of preparedness. We also evaluated the association between preparedness and hospital readmission. RESULTS: Compared to unprepared patients, those who felt prepared were most likely to be given multiple health information resources before surgery (92 vs. 77%, p < 0.001) and before leaving the hospital (91 vs. 69%, p = 0.02). Feeling prepared was positively correlated with the number of resources provided to patients by their surgical team and used before surgery and before leaving the hospital (p < 0.05, both). 30-day readmission was significantly lower among patients who felt prepared either before (7% prepared vs. 22% not prepared, p = <0.001) or after surgery (9% prepared vs. 23% not prepared, p < 0.001). CONCLUSIONS: Patients with access to more health information resources during transitions before and after surgery feel better prepared and have lower rates of 30-day readmission.

Hospital-level Variation in Secondary Complications After Surgery.

OBJECTIVES: To assess whether hospital rates of secondary complications could serve as a performance benchmark and examine associations with mortality. BACKGROUND: Failure to rescue (death after postoperative complication) is a challenging target for quality improvement. Secondary complications (complications after a first or "index" complication) are intermediate outcomes in the rescue process that may provide specific improvement targets and give us insight into how rescue fails. METHODS: We used American College of Surgeons' National Surgical Quality Improvement Program data (2008-2012) to define hospital rates of secondary complications after 5 common index complications: pneumonia, surgical site infection (SSI), urinary tract infection, transfusion/bleed events, and acute myocardial infarction (MI). Hospitals were divided into quintiles on the basis of risk- and reliability-adjusted rates of secondary complications, and these rates were compared along with mortality. RESULTS: A total of 524,860 patients were identified undergoing one of the 62 elective, inpatient operations. After index pneumonia, secondary complication rates varied from 57.99% in the highest quintile to 22.93% in the lowest [adjusted odds ratio (OR), 4.64; confidence interval (CI), 3.95-5.45). Wide variation was seen after index SSI (58.98% vs 14.81%; OR, 8.53; CI, 7.41-9.83), urinary tract infection (38.41% vs 8.60%; OR, 7.81; CI, 6.48-9.40), transfusion/bleeding events (27.14% vs 12.88%; OR, 2.54; CI, 2.31-2.81), and acute MI (64.45% vs 23.86%, OR, 6.87; CI, 5.20-9.07). Hospitals in the highest quintile had significantly greater mortality after index pneumonia (10.41% vs 6.20%; OR, 2.17; CI, 1.6-2.94), index MI (18.25% vs 9.65%; OR, 2.67; CI, 1.80-3.94), and index SSI (2.75% vs 0.82%; OR, 3.93; CI, 2.26-6.81). CONCLUSIONS: Hospital-level rates of secondary complications (failure to arrest complications) vary widely, are associated with mortality, and may be useful for quality improvement and benchmarking.
