Effects of residential socioeconomic polarization on high blood pressure among nursing home residents.

OBJECTIVE: Neighborhood concentration of racial, income, education, and housing deprivation is known to be associated with higher rates of hypertension. The objective of this study is to examine the association between tract-level spatial social polarization and hypertension in a cohort with relatively equal access to health care, a Veterans Affairs nursing home. METHODS: 41,973 long-term care residents aged ≥65 years were matched with tract-level Indices of Concentration at the Extremes across four socioeconomic domains. We modeled high blood pressure against these indices controlling for individual-level cardiovascular confounders. RESULTS: We found participants who had resided in the most disadvantaged quintile had a 1.10 (95% 1.01, 1.19) relative risk of high blood pressure compared to those in the other quintiles for the joint measuring race/ethnicity and income domain. CONCLUSIONS: We achieved our objective by demonstrating that concentrated deprivation is associated with worse cardiovascular outcomes even in a population with equal access to care. Measures that jointly consider economic and racial/ethnic polarization elucidate larger disparities than single domain measures.

Antihypertensive Medication and Fracture Risk in Older Veterans Health Administration Nursing Home Residents.

Importance: Limited evidence exists on the association between initiation of antihypertensive medication and risk of fractures in older long-term nursing home residents. Objective: To assess the association between antihypertensive medication initiation and risk of fracture. Design, Setting, and Participants: This was a retrospective cohort study using target trial emulation for data derived from 29 648 older long-term care nursing home residents in the Veterans Health Administration (VA) from January 1, 2006, to October 31, 2019. Data were analyzed from December 1, 2021, to November 11, 2023. Exposure: Episodes of antihypertensive medication initiation were identified, and eligible initiation episodes were matched with comparable controls who did not initiate therapy. Main Outcome and Measures: The primary outcome was nontraumatic fracture of the humerus, hip, pelvis, radius, or ulna within 30 days of antihypertensive medication initiation. Results were computed among subgroups of residents with dementia, across systolic and diastolic blood pressure thresholds of 140 and 80 mm Hg, respectively, and with use of prior antihypertensive therapies. Analyses were adjusted for more than 50 baseline covariates using 1:4 propensity score matching. Results: Data from 29 648 individuals were included in this study (mean [SD] age, 78.0 [8.4] years; 28 952 [97.7%] male). In the propensity score-matched cohort of 64 710 residents (mean [SD] age, 77.9 [8.5] years), the incidence rate of fractures per 100 person-years in residents initiating antihypertensive medication was 5.4 compared with 2.2 in the control arm. This finding corresponded to an adjusted hazard ratio (HR) of 2.42 (95% CI, 1.43-4.08) and an adjusted excess risk per 100 person-years of 3.12 (95% CI, 0.95-6.78). Antihypertensive medication initiation was also associated with higher risk of severe falls requiring hospitalizations or emergency department visits (HR, 1.80 [95% CI, 1.53-2.13]) and syncope (HR, 1.69 [95% CI, 1.30-2.19]). The magnitude of fracture risk was numerically higher among subgroups of residents with dementia (HR, 3.28 [95% CI, 1.76-6.10]), systolic blood pressure of 140 mm Hg or higher (HR, 3.12 [95% CI, 1.71-5.69]), diastolic blood pressure of 80 mm Hg or higher (HR, 4.41 [95% CI, 1.67-11.68]), and no recent antihypertensive medication use (HR, 4.77 [95% CI, 1.49-15.32]). Conclusions and Relevance: Findings indicated that initiation of antihypertensive medication was associated with elevated risks of fractures and falls. These risks were numerically higher among residents with dementia, higher baseline blood pressures values, and no recent antihypertensive medication use. Caution and additional monitoring are advised when initiating antihypertensive medication in this vulnerable population.

Use of natural language processing method to identify regional anesthesia from clinical notes.

INTRODUCTION: Accurate data capture is integral for research and quality improvement efforts. Unfortunately, limited guidance for defining and documenting regional anesthesia has resulted in wide variation in documentation practices, even within individual hospitals, which can lead to missing and inaccurate data. This cross-sectional study sought to evaluate the performance of a natural language processing (NLP)-based algorithm developed to identify regional anesthesia within unstructured clinical notes. METHODS: We obtained postoperative clinical notes for all patients undergoing elective non-cardiac surgery with general anesthesia at one of six Veterans Health Administration hospitals in California between January 1, 2017, and December 31, 2022. After developing and executing our algorithm, we compared our results to a frequently used referent, the Corporate Data Warehouse structured data, to assess the completeness and accuracy of the currently available data. Measures of agreement included sensitivity, positive predictive value, false negative rate, and accuracy. RESULTS: We identified 27,713 procedures, of which 9310 (33.6%) received regional anesthesia. 96.6% of all referent regional anesthesia cases were identified in the clinic notes with a very low false negative rate and good accuracy (false negative rate=0.8%, accuracy=82.5%). Surprisingly, the clinic notes documented more than two times the number of regional anesthesia cases that were documented in the referent (algorithm n=9154 vs referent n=4606). DISCUSSION: While our algorithm identified nearly all regional anesthesia cases from the referent, it also identified more than two times as many regional anesthesia cases as the referent, raising concerns about the accuracy and completeness of regional anesthesia documentation in administrative and clinical databases. We found that NLP was a promising alternative for identifying clinical information when existing databases lack complete documentation.

Housing Status Changes Are Associated With Cancer Outcomes Among US Veterans.

Cancer is a leading cause of death in older unhoused adults. We assessed whether being unhoused, gaining housing, or losing housing in the year after cancer diagnosis is associated with poorer survival compared with being continuously housed. We examined all-cause survival in more than 100,000 veterans diagnosed with lung, colorectal, and breast cancer during the period 2011-20. Five percent were unhoused at the time of diagnosis, of whom 21 percent gained housing over the next year; 1 percent of veterans housed at the time of diagnosis lost housing. Continuously unhoused veterans and veterans who lost their housing had poorer survival after lung and colorectal cancer diagnosis compared with those who were continuously housed. There was no survival difference between veterans who gained housing after diagnosis and veterans who were continuously housed. These findings support policies to prevent and end homelessness in people after cancer diagnosis, to improve health outcomes.

Mapping the Discharge Process After Surgery.

Importance: Care transition models are structured approaches used to ensure the smooth transfer of patients between health care settings or levels of care, but none currently are tailored to the surgical patient. Tailoring care transition models to the unique needs of surgical patients may lead to significant improvements in surgical outcomes and reduced care fragmentation. The first step to developing surgical care transition models is to understand the surgical discharge process. Objective: To map the surgical discharge process in a sample of US hospitals and identify key components and potential challenges specific to a patient's discharge after surgery. Design, Setting, and Participants: This qualitative study followed a cognitive task analysis framework conducted between January 1, 2022, and April 1, 2023, in Veterans Health Administration (VHA) hospitals. Observations (n = 16) of discharge from inpatient care after a surgical procedure were conducted in 2 separate VHA surgical units. Interviews (n = 13) were conducted among VHA health care professionals nationwide. Exposure: Postoperative hospital discharge. Main Outcomes and Measures: Data were coded according to the principles of thematic analysis, and a swim lane process map was developed to represent the study findings. Results: At the hospitals in this study, the discharge process observed for a surgical patient involved multidisciplinary coordination across the surgery team, nursing team, case managers, dieticians, social services, occupational and physical therapy, and pharmacy. Important components for a surgical discharge that were not incorporated in the current care transition models included wound care education and supplies; pain control; approvals for nonhome postdischarge locations; and follow-up plans for wounds, ostomies, tubes, and drains at discharge. Potential challenges to the surgical discharge process included social situations (eg, home environment and caregiver availability), team communication issues, and postdischarge care coordination. Conclusions and Relevance: These findings suggest that current and ongoing studies of discharge care transitions for a patient after surgery should consider pain control; wounds, ostomies, tubes, and drains; and the impact of challenging social situations and interdisciplinary team coordination on discharge success.

Housing Status, Cancer Care, and Associated Outcomes Among US Veterans.

Importance: Cancer is a leading cause of death among older people experiencing homelessness. However, the association of housing status with cancer outcomes is not well described. Objective: To characterize the diagnosis, treatment, surgical outcomes, and mortality by housing status of patients who receive care from the US Department of Veterans Affairs (VA) health system for colorectal, breast, or lung cancer. Design, Setting, and Participants: This retrospective cohort study identified all US veterans diagnosed with lung, colorectal, or breast cancer who received VA care between October 1, 2011, and September 30, 2020. Data analysis was performed from February 13 to May 9, 2023. Exposures: Veterans were classified as experiencing homelessness if they had any indicators of homelessness in outpatient visits, clinic reminders, diagnosis codes, or the Homeless Operations Management Evaluation System in the 12 months preceding diagnosis, with no subsequent evidence of stable housing. Main Outcomes and Measures: The major outcomes, by cancer type, were as follows: (1) treatment course (eg, stage at diagnosis, time to treatment initiation), (2) surgical outcomes (eg, length of stay, major complications), (3) overall survival by cancer type, and (4) hazard ratios for overall survival in a model adjusted for age at diagnosis, sex, stage at diagnosis, race, ethnicity, marital status, facility location, and comorbidities. Results: This study included 109 485 veterans, with a mean (SD) age of 68.5 (9.7) years. Men comprised 92% of the cohort. In terms of race and ethnicity, 18% of veterans were Black, 4% were Hispanic, and 79% were White. A total of 68% of participants had lung cancer, 26% had colorectal cancer, and 6% had breast cancer. There were 5356 veterans (5%) experiencing homelessness, and these individuals more commonly presented with stage IV colorectal cancer than veterans with housing (22% vs 19%; P = .02). Patients experiencing homelessness had longer postoperative lengths of stay for all cancer types, but no differences in other treatment or surgical outcomes were observed. These patients also demonstrated higher rates of all-cause mortality 3 months after diagnosis for lung and colorectal cancers, with adjusted hazard ratios of 1.1 (95% CI, 1.1-1.2) and 1.3 (95% CI, 1.2-1.4) (both P < .001), respectively. Conclusions and Relevance: In this large retrospective study of US veterans with cancer, homelessness was associated with later stages at diagnosis for colorectal cancer. Differences in lung and colorectal cancer survival between patients with housing and those experiencing homelessness were present but smaller than observed in other settings. These findings suggest that there may be important systems in the VA that could inform policy to improve oncologic outcomes for patients experiencing homelessness.

Association Between Self-Reported Health and Reliance on Veterans Affairs for Health Care Among Veterans Affairs Enrollees.

This cross-sectional study using survey data investigates the association between level of reliance on the Department of Veterans Affairs for health care and self-reported health by type of insurance coverage among VA enrollees.

Systolic blood pressure, antihypertensive treatment, and cardiovascular and mortality risk in VA nursing home residents.

BACKGROUND: Optimal systolic BP (SBP) control in nursing home residents is uncertain, largely because this population has been excluded from clinical trials. We examined the association of SBP levels with the risk of cardiovascular (CV) events and mortality in Veterans Affairs (VA) nursing home residents on different numbers of antihypertensive medications. METHODS: Our study included 36,634 residents aged ≥65 years with a VA nursing home stay of ≥90 days from October 2006-June 2019. SBP was averaged over the first week after admission and divided into categories. Cause-specific hazard ratios (HRs) of SBP categories with CV events (primary outcome) and all-cause mortality (secondary outcome) were examined using Cox regression and multistate modeling stratified by the number of antihypertensive medications used at admission (0, 1 or 2, and ≥3 medications). RESULTS: More than 76% of residents were on antihypertensive therapy and 20% received ≥3 medications. In residents on antihypertensive therapy, a low SBP < 110 mmHg (compared with SBP 130 ~ 149 mmHg) was associated with a greater CV risk (adjusted HR [95% confidence interval]: 1.47 [1.28-1.68] in 1 or 2 medications group, and 1.41 [1.19-1.67] in ≥3 medications group). In residents on no antihypertensives, both low SBP < 110 mmHg and high SBP ≥ 150 mmHg were associated with higher mortality; while in residents receiving any antihypertensives, a low SBP was associated with higher mortality and the highest point estimates were for SBP < 110 mmHg (1.36 [1.28-1.45] in 1 or 2 medications group, and 1.47 [1.31-1.64] in ≥3 medications group). CONCLUSIONS: The associations of SBP with CV and mortality risk varied by the intensity of antihypertensive treatment among VA nursing home residents. A low SBP among those receiving antihypertensives was associated with increased CV and mortality risk, and untreated high SBP was associated with higher mortality. More research is needed on the benefits and harms of SBP lowering in long-term care populations.

Applying cognitive task analysis to health services research.

OBJECTIVE: Designing practical decision support tools and other health care technology in health services research relies on a clear understanding of the cognitive processes that underlie the use of these tools. Unfortunately, methods to explore cognitive processes are rarely used in health services research. Thus, the objective of this manuscript is to introduce cognitive task analysis (CTA), a family of methods to study cognitive processes involved in completing a task, to a health services research audience. This methods article describes CTA procedures, proposes a framework for their use in health services research studies, and provides an example of its application in a pilot study. DATA SOURCES AND STUDY SETTING: Observations and interviews of health care providers involved in discharge planning at six hospitals in the Veterans Health Administration. STUDY DESIGN: Qualitative study of discharge planning using CTA. DATA COLLECTION/EXTRACTION METHODS: Data were collected from structured observations and semi-structured interviews using the Critical Decision Method and analyzed using thematic analysis. PRINCIPAL FINDINGS: We developed an adaptation of CTA that could be used in a clinical environment to describe clinical decision-making and other cognitive processes. The adapted CTA framework guides the user through four steps: (1) Planning, (2) Environmental Analysis, (3) Knowledge Elicitation, and (4) Analyses and Results. This adapted CTA framework provides an iterative and systematic approach to identifying and describing the knowledge, expertise, thought processes, procedures, actors, goals, and mental strategies that underlie completing a clinical task. CONCLUSIONS: A better understanding of the cognitive processes that underly clinical tasks is key to developing health care technology and decision-support tools that will have a meaningful impact on processes of care and patient outcomes. Our adapted framework offers a more rigorous and detailed method for identifying task-related cognitive processes in implementation studies and quality improvement. Our adaptation of this underutilized qualitative research method may be helpful to other researchers and inform future research in health services research.

Expansion of the Veterans Health Administration Network and Surgical Outcomes.

Importance: The US Department of Veterans Affairs (VA) Veterans Choice Program (VCP) expanded health care access to community settings outside the VA for eligible patients. Little is known about the effect of VCP on access to surgery and postoperative outcomes. Since its initiation, care coordination issues, which are often associated with adverse postoperative outcomes, have been reported. Research findings on the association of VCP and postoperative outcomes are limited to only a few select procedures and have been mixed, potentially due to bias from unmeasured confounding. Objective: To investigate the association of the VCP with access to surgery and postoperative outcomes using a nonrandomized controlled regression discontinuity design (RDD) to reduce the impact of unmeasured confounders. Design, Setting, and Participants: This was a nonrandomized RDD study of the Veterans Health Administration (VHA). Participants included veterans enrolled in the VHA who required surgery between October 1, 2014, and June 1, 2019. Interventions: The VCP, which expanded access to VA-paid community care for eligible veterans living 40 miles or more from their closest VA hospital. Main Outcomes and Measures: Postoperative emergency department visits, inpatient readmissions, and mortality at 30 and 90 days. Results: A total of 615 473 unique surgical procedures among 498 427 patients (mean [SD] age, 63.0 [12.9] years; 450 366 male [90.4%]) were identified. Overall, 94 783 procedures (15.4%) were paid by the VHA, and the proportion of VHA-paid procedures varied by procedure type. Patients who underwent VA-paid procedures were more likely to be women (9209 [12.7%] vs men, 38 771 [9.1%]), White race (VA paid, 54 544 [74.4%] vs VA provided, 310 077 [73.0%]), and younger than 65 years (VA paid, 36 054 [49.1%] vs 229 411 [46.0%] VA provided), with a significantly lower comorbidity burden (mean [SD], 1.8 [2.2] vs 2.6 [2.7]). The nonrandomized RDD revealed that VCP was associated with a slight increase of 0.03 in the proportion of VA-paid surgical procedures among eligible veterans (95% CI, 0.01-0.05; P = .01). However, there was no difference in postoperative mortality, readmissions, or emergency department visits. Conclusions and Relevance: Expanded access to health care in the VHA was associated with a shift in the performance of surgical procedures in the private sector but had no measurable association with surgical outcomes. These findings may assuage concerns of worsened patient outcomes resulting from care coordination issues when care is expanded outside of a single health care system, although it remains unclear whether these additional procedures were appropriate or improved patient outcomes.

Quality Reporting Windows May Not Capture the Effects of Surgical Site Infections After Orthopaedic Surgery.

BACKGROUND: Postoperative surgical site infections (SSIs) and the associated complications impact morbidity and mortality and result in substantial burden to the health-care system. These complications are typically reported during the 90-day surveillance period, with implications for reimbursement and quality measurement; however, the long-term effects of SSI are not routinely assessed. We evaluated the long-term effects of SSI on health-care utilization and cost following orthopaedic surgery in an observational cohort study. METHODS: Patients in the Veterans Affairs health-care system who underwent an orthopaedic surgical procedure were included. The exposure of interest was an SSI within 90 days after the index procedure. The primary outcome was health-care utilization in the 2 years after discharge. Data for inpatient admission, inpatient days, outpatient visits, emergency room visits, total costs, and subsequent surgeries were also obtained. After adjusting for factors affecting SSI, we examined differences in each health-care utilization outcome by postoperative SSI occurrence and across time with use of differences-in-differences analysis. Cost differences were modeled with use of a gamma distribution with a log link. RESULTS: A total of 96,983 patients were included, of whom 4,056 (4.2%) had an SSI within 90 days of surgery. After adjusting for factors known to impact SSI and preoperative health-care utilization, SSI was associated with a greater risk of outpatient visits (relative risk [RR], 1.29; 95% confidence interval [CI], 1.26 to 1.32), emergency room visits (RR, 1.18; 95% CI, 1.15 to 1.21), and inpatient admission (RR, 1.35; 95% CI, 1.32 to 1.38) at 2 years postoperatively. The average cost among patients with an SSI was $148,824 ± $268,358 compared with $42,125 ± $124,914 among those without an SSI (p < 0.001). In the adjusted analysis, costs for patients with an SSI were 64% greater at 2 years compared with those without an SSI (RR, 1.64; 95% CI, 1.57 to 1.70). Overall, of all subsequent surgeries conducted within the 2-year postoperative period, 37% occurred within the first 90 days. CONCLUSIONS: The reported effects of a postoperative SSI on health-care utilization and cost are sustained at 2 years post-surgery-a long-term impact that is not recognized in quality-measurement models. Efforts, including preoperative care pathways and optimization, and policies, including reimbursement models and risk-adjustment, should be made to reduce SSI and to account for these long-term effects. LEVEL OF EVIDENCE: Economic Level IV. See Instructions for Authors for a complete description of levels of evidence.

Trends in blood pressure diagnosis, treatment, and control among VA nursing home residents, 2007-2018.

BACKGROUND: Inadequate treatment of high blood pressure (BP) can lead to preventable adverse events in nursing home residents, while excessive treatment can lead to associated harms. METHODS: Data were extracted from the VA electronic health record and Bar Code Medication Administration system on 40,079 long-term care residents aged ≥65 years from October 2006 through September 2018 (FY2007-2018). Hypertension prevalence at admission was identified by ICD code(s) in the year prior, and antihypertensive medication use was defined as administration ≥50% of days. BP measures were averaged over 2-year epochs. RESULTS: The age-standardized prevalence of hypertension diagnosis at admission increased from 75.2% in FY2007-2008 to 85.1% in FY2017-2018 (p-value for trend <0.001). Rates of BP treatment and control among residents with hypertension at admission declined slightly over time (p-values for trend <0.001) but remained high (80.3% treated in FY2017-2018, 80.1% with average BP <140/90 mmHg). The age-adjusted prevalence of chronic low BP (average <90/60 mmHg) also declined from 11.1% in FY2007-2008 to 4.7% in FY2017-2018 (p-value for trend <0.001). Persons identified as Black race or Hispanic ethnicity and those with a history of diabetes, stroke, and renal disease were less likely to have an average BP <140/90 mmHg. CONCLUSIONS: Hypertension is well controlled in VA nursing homes, and recent trends of less intensive BP control were accompanied by a lower prevalence of chronic low BP. Nonetheless, some high-risk populations have average BP levels >140/90 mmHg. Future research is needed to better understand the benefits and harms of BP control in nursing home residents.

Challenging weekend discharges associated with excess length of stay in surgical patients at Veterans Affairs hospitals.

BACKGROUND: Challenging discharges can lead to prolonged hospital stays. We hypothesized that surgical patients discharged from Veterans Affairs hospitals on weekdays have longer hospital stays and greater excess length of stay. METHODS: We identified inpatient general and vascular procedures at Veterans Affairs hospitals from 2007 to 2014. Expected length of stay was calculated using a stratified negative binomial model adjusted for patient/operative characteristics. Excess length of stay was defined as the difference between observed and expected length of stay. RESULTS: We identified 135,875 patients (80.4% weekday discharges, 19.6% weekend discharges). The average length of stay was 7.5 days. Patients with weekday discharges spent on average 2.5 more days in the hospital compared with patients discharged on weekends (8.0 vs. 5.5 days, P < .001); 28.5% of patients with weekday discharges had an observed length of stay at least 1 day longer than expected, compared with 16.4% of patients with weekend discharges (P < .001). CONCLUSION: Surgical patients are less frequently discharged from Veterans Affairs hospitals on the weekends than during the week, and this corresponds to an increased excess length of stay for patients ultimately discharged on weekdays. Exploring the opportunity to coordinate safe weekend discharges may improve efficiency of post-surgery hospital care and reduce healthcare costs.

Exploring the Dynamics of Week-to-Week Blood Pressure in Nursing Home Residents Before Death.

BACKGROUND: Aging is accompanied by an overall dysregulation of many dynamic physiologic processes including those related to blood pressure (BP). While year-to-year BP variability is associated with cardiovascular events and mortality, no studies have examined this trend with more frequent BP assessments. Our study objective is to take the next step to examine week-to-week BP dynamics-pattern, variability, and complexity-before death. METHODS: Using a retrospective study design, we assessed BP dynamics in the 6 months before death in long-term nursing home residents between 1 October 2006 and 30 September 2017. Variability was characterized using SD and mean squared error after adjusting for diurnal variations. Complexity (i.e., amount of novel information in a trend) was examined using Shannon's entropy (bits). Generalized linear models were used to examine factors associated with overall BP variability. RESULTS: We identified 17,953 nursing home residents (98.0% male, 82.5% White, mean age 80.2 years, and mean BP 125.7/68.6 mm Hg). Despite a slight trend of decreasing systolic week-to-week BP over time (delta = 7.2 mm Hg), week-to-week complexity did not change in the 6 months before death (delta = 0.02 bits). Average weekly BP variability was stable until the last 3-4 weeks of life, at which point variability increased by 30% for both systolic and diastolic BP. Factors associated with BP variability include average weekly systolic/diastolic BP, days in the nursing home, days in the hospital, and changes to antihypertensive medications. CONCLUSIONS: Week-to-week BP variability increases substantially in the last month of life, but complexity does not change. Changes in care patterns may drive the increase in BP variability as one approaches death.

Timing and Cost of Wound Complications After Colorectal Resection.

BACKGROUND: More than 50% of postoperative wound complications occur after discharge. They are the most common postoperative complication and the most common reason for readmission after a surgical procedure. Little is known about the long-term costs of postdischarge wound complications after surgery. OBJECTIVE: We sought to understand the differences in costs and characteristics of wound complications identified after hospital discharge for patients undergoing colorectal surgery in comparison with in-hospital complications. DESIGN: This is an observational cohort study using Veterans Health Administration Surgical Quality Improvement Program data. SETTING: This study was conducted at a Veterans Affairs medical center. SETTING: Patients undergoing colorectal resection between October 1, 2007 and September 30, 2014. MAIN OUTCOME MEASURES: The primary outcomes measured were adjusted costs of care at discharge, 30 days, and 90 days after surgery. RESULTS: Of 20,146 procedures, 11.9% had a wound complication within 30 days of surgery (49.2% index-hospital, 50.8% postdischarge). In comparison with patients with index-hospital complications, patients with postdischarge complications had fewer superficial infections (65.0% vs 72.2%, p < 0.01), more organ/space surgical site infections (14.3% vs 10.1%, p < 0.01), and higher rates of diabetes (29.1% vs 25.0%, p = 0.02), and they were to have had a laparoscopic approach for their surgery (24.7% vs 18.2%, p < 0.01). The average cost including surgery at 30 days was $37,315 (SD = $29,319). Compared with index-hospital wound complications, postdischarge wound complications were $9500 (22%, p < 0.001) less expensive at 30 days and $9736 (15%, p < 0.001) less expensive at 90 days. Patients with an index-hospital wound complication were 40% less likely to require readmission at 30 days, but their readmissions were $12,518 more expensive than readmissions among patients with a newly identified postdischarge wound complication (p < 0.001). LIMITATIONS: This study was limited to patient characteristics and costs accrued only within the Veterans Affairs system. CONCLUSIONS: Patients with postdischarge wound complications have lower 30- and 90-day postoperative costs than those with wound complications identified during their index hospitalization and almost half were managed as an outpatient. TIEMPO Y COSTO DE LAS COMPLICACIONES LA HERIDA DESPUS DE LA RESECCIN COLORRECTAL: ANTECEDENTES:Más del 50% de complicaciones postoperatorias de la herida ocurren después del alta. Es la complicación postoperatoria más común y el motivo más frecuente de reingreso después del procedimiento quirúrgico. Poco se sabe sobre los costos a largo plazo de las complicaciones de la herida después del alta quirúrgica.OBJETIVO:Intentar en comprender las diferencias en los costos y las características de las complicaciones de la herida, identificadas después del alta hospitalaria, en pacientes sometidos a cirugía colorrectal, en comparación con las complicaciones intrahospitalarias.DISEÑO:Estudio de cohorte observacional utilizando datos del Programa de Mejora de la Calidad Quirúrgica de la Administración de Salud de Veteranos.ENTORNO CLÍNICO:Administración de Veteranos.PACIENTES:Pacientes sometidos a resección colorrectal entre el 1/10/2007 y el 30/9/2014.PRINCIPALES MEDIDAS DE VALORACIÓN:Costos de atención ajustados al alta, 30 días y 90 días después de la cirugía.RESULTADOS:De 20146 procedimientos, el 11,9% tuvo una complicación de la herida dentro de los 30 días de la cirugía. (49,2% índice hospitalario, 50,8% después del alta). En comparación con los pacientes, del índice de complicaciones hospitalarias, los pacientes con complicaciones posteriores al alta, tuvieron menos infecciones superficiales (65,0% frente a 72,2%, p <0,01), más infecciones de órganos/espacios quirúrgicos (14,3% frente a 10,1%, p <0,01), tasas más altas de diabetes (29,1% versus 25,0%, p = 0,02), y deberían de haber tenido un abordaje laparoscópico para su cirugía (24,7% versus 18,2%, p <0,01). El costo promedio, incluida la cirugía a los 30 días, fue de $ 37,315 (desviación estándar = $ 29,319). En comparación con el índice de complicaciones de las herida hospitalaria, las complicaciones de la herida después del alta fueron $ 9,500 (22%, p <0,001) menor costo a los 30 días y $ 9,736 (15%, p<0,001) y menor costo a los 90 días. Los pacientes con índice de complicación de la herida hospitalaria, tenían un 40% menos de probabilidades de requerir reingreso a los 30 días, pero sus reingresos eran $ 12,518 más costosos que los reingresos entre los pacientes presentando complicación de la herida recién identificada después del alta (p <0,001).LIMITACIONES:Limitado a las características del paciente y los costos acumulados solo dentro del sistema VA.CONCLUSIONES:Pacientes con complicaciones de la herida post alta, tienen menores costos postoperatorios a los 30 y 90 días, que aquellos con complicaciones de la herida identificadas durante su índice de hospitalización y aproximadamente la mitad fueron tratados de forma ambulatoria.

Psychosocial Determinants of Readmission After Surgery.

BACKGROUND: Quality of life and psychosocial determinants of health, such as health literacy and social support, are associated with increased health care utilization and adverse outcomes in medical populations. However, the effect on surgical health care utilization is less understood. OBJECTIVE: We sought to examine the effect of patient-reported quality of life and psychosocial determinants of health on unplanned hospital readmissions in a surgical population. RESEARCH DESIGN: This is a prospective cohort study using patient interviews at the time of hospital discharge from a Veterans Affairs hospital. SUBJECTS: We include Veterans undergoing elective inpatient general, vascular, or thoracic surgery (August 1, 2015-June 30, 2017). MEASURES: We assessed unplanned readmission to any medical facility within 30 days of hospital discharge. RESULTS: A total of 736 patients completed the 30-day postoperative follow-up, and 16.3% experienced readmission. Lower patient-reported physical and mental health, inadequate health literacy, and discharge home with help after surgery or to a skilled nursing or rehabilitation facility were associated with an increased incidence of readmission. Classification regression identified the patient-reported Veterans Short Form 12 (SF12) Mental Component Score <31 as the most important psychosocial determinant of readmission after surgery. CONCLUSIONS: Mental health concerns, inadequate health literacy, and lower social support after hospital discharge are significant predictors of increased unplanned readmissions after major general, vascular, or thoracic surgery. These elements should be incorporated into routinely collected electronic health record data. Also, discharge plans should accommodate varying levels of health literacy and consider how the patient's mental health and social support needs will affect recovery.

Impact of Gastrointestinal Surgical Site Wound Complications on Long-term Healthcare Utilization.

IMPORTANCE: Wound complication following gastrointestinal surgery substantially impacts the quality and costs of surgical care. The impact of wound complication on subsequent long-term healthcare utilization has not been fully studied. OBJECTIVE: We assessed the impact of surgical wound complication on inpatient and outpatient healthcare utilization in the 2 years after gastrointestinal (GI) surgery. DESIGN: An observational retrospective cohort study was conducted on Veterans Affairs health system patients who underwent an inpatient GI surgical procedure, were assessed by the Veterans Affairs Surgical Quality Improvement Program (VASQIP), and were discharged alive from Veterans Affairs (VA) hospitals between October 1, 2007 and September 30, 2014. SETTING: Population-based PARTICIPANTS: A total of 64,351 patients underwent a GI surgical procedure in the VA system between 2007 and 2014. The cohort was 93.5% male, with a median age of 63.0 years (interquartile range (IQR) 57.0-70.0). A total of 7880 patients (12.2%) had at least one reported wound complication, 5460 of which had their postoperative wound complication classified by a VASQIP nurse. EXPOSURE: VASQIP-assessed or ICD-9-coded wound complication in the 30 days after surgery MAIN OUTCOME MEASUREMENTS: Inpatient visits, total inpatient days, outpatient visits, and emergency department visits, and operative interventions up to 2 years after discharge from index admission RESULTS: Patients with a postoperative wound complication had greater inpatient healthcare utilization compared with no-wound complication for up to 2 years after surgery: inpatient admissions (mean number 3.5 vs. 2.8; P < .001), inpatient bed days (mean 41.0 vs. 25.0; P < .001). Patients with a postoperative wound complication also had greater 2-year outpatient utilization than the no-wound complication cohort: outpatient visits (mean number 92.7 vs. 75.9; P < .001) and emergency department visits (mean 3.5 vs. 2.7; P < .001). The same relationship held for wound-related parameters; inpatient admissions (2.2 vs. 0.4; P < .001); inpatient bed days (21.4 vs. 3.7; P < .001); and outpatient visits (56.2 vs. 9.7; P < .001). A greater proportion of patients in the wound complication cohort had an operative intervention for all time intervals examined (P < .001). CONCLUSIONS: Surgical wound complications impact healthcare utilization patterns for up to 2 years after the index procedure including hospital readmissions and operative interventions; efforts to reduce postoperative wound complications will have substantial effects on patient outcomes and healthcare expenditures well beyond the 30-day postoperative period.

Perioperative opioid use and pain-related outcomes in the Veterans Health Administration.

Understanding variation in perioperative opioid exposure and its effect on patients' outcomes is critical for pain management. This study characterized perioperative exposure to morphine and its association with postoperative pain and 30-day readmissions. We utilized nationwide Veterans Healthcare Administration (VHA) data on four high-volume surgical procedures, 2007-2014. We identified 235,239 Veterans undergoing orthopedic, general, or vascular surgery; 5.4% high trajectories (116.1 OME/Day), 53.2% medium trajectories (39.7 OME/Day), and 41.4% low trajectories (19.1 OME/Day). Modeled estimates suggest that patients in the high OME group had higher risk of a pain-related readmission (OR: 1.59; CI: 1.39, 1.83) compared to the low OME trajectory. Yet when stratified by pain trajectory, patients with high pain and high OME had lower risk of a pain-related readmission compared to patients in the high pain low OME group (OR: 0.76, CI: 0.62, 0.94). In conclusion, patients receiving high perioperative OME are more likely to return to care for pain-related problems. This study highlights opportunities to reduce the amount of prescriptions opioids in the communities.
