ABSTRACT: Background
Understanding risk factors for short- and long-term COVID-19 outcomes have implications for current guidelines and practice. We study whether early identified risk factors for COVID-19 persist one year later and through varying disease progression trajectories.Methods
This was a retrospective study of 6,731 COVID-19 patients presenting to Michigan Medicine between March 10, 2020 and March 10, 2021. We describe disease progression trajectories from diagnosis to potential hospital admission, discharge, readmission, or death. Outcomes pertained to all patients: rate of medical encounters, hospitalization-free survival, and overall survival, and hospitalized patients: discharge versus in-hospital death and readmission. Risk factors included patient age, sex, race, body mass index, and 29 comorbidity conditions.Results
Younger, non-Black patients utilized healthcare resources at higher rates, while older, male, and Black patients had higher rates of hospitalization and mortality. Diabetes with complications, coagulopathy, fluid and electrolyte disorders, and blood loss anemia were risk factors for these outcomes. Diabetes with complications, coagulopathy, fluid and electrolyte disorders, and blood loss were associated with lower discharge and higher inpatient mortality rates.Conclusions
This study found differences in healthcare utilization and adverse COVID-19 outcomes, as well as differing risk factors for short- and long-term outcomes throughout disease progression. These findings may inform providers in emergency departments or critical care settings of treatment priorities, empower healthcare stakeholders with effective disease management strategies, and aid health policy makers in optimizing allocations of medical resources.

Project description:IntroductionShort-bowel syndrome (SBS) is a common cause of chronic intestinal failure and is associated with increased morbidity, mortality, poor quality of life, and an increased burden on healthcare costs.MethodsWe used the US Nationwide Inpatient Sample database from 2005 to 2014. We identified adult SBS hospitalizations by using a combination of International Classification of Diseases, Ninth Revision, Clinical Modification codes. We studied the demographics of the patients with SBS and analyzed the trends in the number of hospitalizations, in-hospital mortality, and healthcare costs. We also identified the risk factors associated with in-hospital mortality.ResultsA total of 53,040 SBS hospitalizations were identified. We found that SBS-related hospitalizations increased by 55% between 2005 (N = 4037) and 2014 (N = 6265). During this period, the in-hospital mortality decreased from 40 per 1000 to 29 per 1000 hospitalizations, resulting in an overall reduction of 27%. Higher mortality was noted in SBS patients with sepsis (6.7%), liver dysfunction (6.2%), severe malnutrition (6.0%), and metastatic cancer (5.4%). The overall mean length of stay (LOS) for SBS-related hospitalizations was 14.7 days, with a mean hospital cost of $34,130. We noted a steady decrease in the LOS, whereas the cost of care remained relatively stable.ConclusionsThe national burden of SBS-related hospitalizations continues to rise, and the mortality associated with SBS has substantially decreased. Older SBS patients with sepsis, liver dysfunction, severe malnutrition, and metastatic cancer had the highest risk of mortality. Healthcare utilization in SBS remains high. healthcare utilization; hospitalization trend; mortality; research and diseases; short-bowel syndrome.

Project description:Healthcare providers are routinely being assessed for metrics designed to assess the quality of the care they deliver. There is growing consensus that these measurements, which typically assess the percentage of patients meeting a specific standard of care, should be adjusted for the clinical complexity of the providers. This study will assess whether adjusting for the social complexity of the patient panel adds significantly to adjustment for clinical complexity in explaining apparent differences in quality of care provided by Primary care providers and clinics.

Project description:AimsTo implement pharmacist-led, postdischarge telephone follow-up (TFU) intervention and to evaluate its impact on rehospitalization parameters in polypharmacy patients, via comparison with a well-matched control group.MethodPragmatic, prospective, quasi-experimental study. Intervention patients were matched by propensity score techniques with a control group. Guided by results from a pilot study, clinical pharmacists implemented TFU intervention, added to routine integrated medicines management service.ResultsUsing an intention to treat approach, reductions in 30- and 90-day readmission rates for intervention patients compared with controls were 9.9% [odds ratio = 0.57; 95% confidence interval (CI): 0.36-0.90; P < 0.001] and 15.2% (odds ratio = 0.53; 95% CI: 0.36-0.79; P = 0.021) respectively. Marginal mean time to readmission was 70.9 days (95% CI: 66.9-74.9) for intervention group compared with 60.1 days (95% CI: 55.4-64.7) for controls. Mean length of hospital stay compared with control was (8.3 days vs. 6.7 days; P < 0.001). Benefit: cost ratio for 30-day readmissions was 29.62, and 23.58 for 90-day interval. Per protocol analyses gave more marked improvements. In intervention patients, mean concern scale score, using Beliefs about Medicine Questionnaire, was reduced 3.2 (95% CI: -4.22 to -2.27; P < 0.001). Mean difference in Medication Adherence Report Scale was 1.4 (22.7 vs. 24.1; P < 0.001). Most patients (83.8%) reported having better control of their medicines after the intervention.ConclusionsPharmacist-led postdischarge structured TFU intervention can reduce 30- and 90-day readmission rates. Positive impacts were noted on time to readmission, length of hospital stay upon readmission, healthcare costs, patient beliefs about medicines, patient self-reported adherence and satisfaction.

Project description:BackgroundHospital associated infections are major problems, which are increasing in incidence and very costly. However, most research has focused only on measuring consequences associated with the initial hospitalization. We explored the long-term consequences of infections in elderly Medicare patients admitted to an intensive care unit (ICU) and discharged alive, focusing on: sepsis, pneumonia, central-line-associated bloodstream infections (CLABSI), and ventilator-associated pneumonia (VAP); the relationships between the infections and long-term survival and resource utilization; and how resource utilization was related to impending death during the follow up period.MethodsClinical data and one year pre- and five years post-index hospitalization Medicare records were examined. Hazard ratios (HR) and healthcare utilization incidence ratios (IR) were estimated from state of the art econometric models. Patient demographics (i.e., age, gender, race and health status) and Medicaid status (i.e., dual eligibility) were controlled for in these models.ResultsIn 17,537 patients, there were 1,062 sepsis, 1,802 pneumonia, 42 CLABSI and 52 VAP cases. These subjects accounted for 62,554 person-years post discharge. The sepsis and CLABSI cohorts were similar as were the pneumonia and VAP cohorts. Infection was associated with increased mortality (sepsis HR = 1.39, P < 0.01; and pneumonia HR = 1.58, P < 0.01) and the risk persisted throughout the follow-up period. Persons with sepsis and pneumonia experienced higher utilization than controls (e.g., IR for long-term care utilization for those with sepsis ranged from 2.67 to 1.93 in years 1 through 5); and, utilization was partially related to impending death.ConclusionsThe infections had significant and lasting adverse consequences among the elderly. Yet, many of these infections may be preventable. Investments in infection prevention interventions are needed in both community and hospitals settings.

Project description:BackgroundImpaired physical functional status is one of the typical long-term sequelae of COVID-19 infection that significantly affects the quality of life and work capacity. Minor changes in cardiac structure and function that are unable to cause the manifestation of overt heart failure may remain undetected in COVID-19 convalescents, at the same time potentially contributing to the persistence of symptoms and development of long COVID syndrome.PurposeTo study the typical features and short-term dynamics of cardiac remodeling and possible signs of cardiac dysfunction following hospitalization for COVID-19.MethodsThis is a combined cross-sectional and longitudinal cohort study in which 176 hospitalized patients (93 female and 83 male, mean age 53.4 ± 13.6 years) with COVID-19 infection underwent comprehensive transthoracic echocardiography pre-discharge (22.6 ± 7.1 days from the onset of symptoms) with repeated evaluation after 1 month. The control group included 88 age-, sex-, height- and weight-matched healthy individuals, with a subset of those (n = 53) matched to the subset of non-hypertensive study participants (n = 106).ResultsConcentric left ventricular geometry was revealed in 59% of participants, including 43% of non-hypertensive subjects; predominantly Grade I diastolic dysfunction was found in 35 and 25% of patients, respectively. Other findings were naturally following from described phenotype of the left venticle and included a mild increase in the absolute and relative wall thickness (0.45 ± 0.07 vs. 0.39 ± 0.04, p < 0.001), worsening of diastolic indices (e' velocity 9.2 ± 2.2 vs. 11.3 ± 2.6 cm/s, p < 0.001, E/e' ratio 7.5 ± 1.8 vs. 6.8 ± 1.7, p = 0.002) and global longitudinal strain (17.5 ± 2.4 vs. 18.6 ± 2.2, p < 0.001). No significant improvement was found on re-evaluation at 1 month.ConclusionsHospitalized patients recovering from COVID-19 were characterized by a high prevalence of left ventricular concentric remodeling, predominantly Grade I diastolic dysfunction, and a mild decrease in the longitudinal systolic function. These changes were less frequent but still prevalent in the non-hypertensive subgroup and largely persisted throughout the 1-month follow-up.

Project description:PURPOSE:Bariatric surgery represents an appropriate treatment for adolescent severe obesity, but its utilization remains low in this patient population. We studied the impact of race and sex on preoperative characteristics, outcomes, and utilization of adolescent bariatric surgery. METHODS:Retrospective analysis (2007-2014) of adolescent bariatric surgery using the Bariatric Outcomes Longitudinal Database, a national database that collects bariatric surgical care data. We assessed the relationships between baseline characteristics and outcomes (weight loss and remission of obesity-related conditions [ORCs]). Using the National Health and Nutrition Examination Survey and U.S. census data, we calculated the ratio of severe obesity and bariatric procedures among races and determined the ratio of ratios to assess for disparities. RESULTS:About 1,539 adolescents underwent bariatric surgery. Males had higher preoperative body mass index (BMI; 51.8 ± 10.5 vs. 47.1 ± 8.7, p < .001) and higher rates of obstructive sleep apnea and dyslipidemia. Blacks had higher preoperative BMI (52.4 ± 10.6 vs. 47.3 ± 8.3; 48.7 ± 8.8; 48.2 ± 12.1 kg/m2; whites, Hispanics, and others, respectively p < .001) and higher rates of hypertension, obstructive sleep apnea, and asthma. Weight loss and ORCs remission rates did not differ between sexes or races after accounting for the rate of severe obesity in each racial group. White adolescents underwent bariatric surgery at a higher proportion than blacks and Hispanics (2.5 and 2.3 times higher, respectively). CONCLUSIONS:Preoperative characteristics vary according to race and sex. Race and sex do not impact 12-month weight loss or ORC's remission rates. Minority adolescents undergo bariatric surgery at lower-than-expected rates.

Project description:BackgroundDisparities in health outcome exist among patients according to socioeconomic status. However, little is known regarding the differences in healthcare experiences across the various levels of income of patients. In a nationally representative US adult population, we evaluate the differences in healthcare experiences based on patient level of income.ObjectivesTo evaluate the differences in patient healthcare experiences based on level of income.Patients and methodsWe identified 68,447 individuals (mean age, 48 ± 18 years; 55% female) representing 176.8 million US adults, who had an established healthcare provider in the 2010-2013 Medical Expenditure Panel Survey cohort. This retrospective study examined the differences in all five patient-reported healthcare experience measures (access to care, provider responsiveness, patient-provider communication, shared decision-making, and patient satisfaction) under the Consumer Assessment of Healthcare Providers and Systems (CAHPS) survey. We examined the relationship between patient income and their healthcare experience.ResultsOverall, 32% of the study participants were high-income earners while 23% had very-low income. Lower income was consistently associated with poor patient report on healthcare experience. Compared with those with high income, very-low-income-earning participants had 1.63 times greater odds (OR 1.63, 95% CI 1.45-1.82) of experiencing difficulty accessing care, had 1.34 times higher odds (OR 1.34, 95% CI 1.25-1.45) of experiencing poor communication, had higher odds (OR 1.68, 95% CI 1.46-1.92) of experiencing delays in healthcare delivery, and were more likely to report poor provider satisfaction (OR 1.48, 95% CI 1.37-1.61).ConclusionLower income-earning patients have poorer healthcare experience in all aspects of access and quality of care. Targeted policies focusing on improving communication, engagement, and satisfaction are needed to enhance patient healthcare experience for this vulnerable population.

Project description:BackgroundLimited data exists evaluating predictors of long-term outcomes after hospitalization for COVID-19.MethodsWe conducted a prospective, longitudinal cohort study of patients hospitalized for COVID-19. The following outcomes were collected at 6 and 12-months post-diagnosis: disability using the modified Rankin Scale (mRS), activities of daily living assessed with the Barthel Index, cognition assessed with the telephone Montreal Cognitive Assessment (t-MoCA), Neuro-QoL batteries for anxiety, depression, fatigue and sleep, and post-acute symptoms of COVID-19. Predictors of these outcomes, including demographics, pre-COVID-19 comorbidities, index COVID-19 hospitalization metrics, and life stressors, were evaluated using multivariable logistic regression.ResultsOf 790 COVID-19 patients who survived hospitalization, 451(57%) completed 6-month (N = 383) and/or 12-month (N = 242) follow-up, and 77/451 (17%) died between discharge and 12-month follow-up. Significant life stressors were reported in 121/239 (51%) at 12-months. In multivariable analyses, life stressors including financial insecurity, food insecurity, death of a close contact and new disability were the strongest independent predictors of worse mRS, Barthel Index, depression, fatigue, and sleep scores, and prolonged symptoms, with adjusted odds ratios ranging from 2.5 to 20.8. Other predictors of poor outcome included older age (associated with worse mRS, Barthel, t-MoCA, depression scores), baseline disability (associated with worse mRS, fatigue, Barthel scores), female sex (associated with worse Barthel, anxiety scores) and index COVID-19 severity (associated with worse Barthel index, prolonged symptoms).ConclusionsLife stressors contribute substantially to worse functional, cognitive and neuropsychiatric outcomes 12-months after COVID-19 hospitalization. Other predictors of poor outcome include older age, female sex, baseline disability and severity of index COVID-19.

Project description:BackgroundAnesthesiologists require an understanding of their patients' outcomes to evaluate their performance and improve their practice. Traditionally, anesthesiologists had limited information about their surgical outpatients' outcomes due to minimal contact post discharge. Leveraging digital health innovations for analyzing personal and population outcomes may improve perioperative care. BC Children's Hospital's postoperative follow-up registry for outpatient surgeries collects short-term outcomes such as pain, nausea, and vomiting. Yet, these data were previously not available to anesthesiologists.ObjectiveThis quality improvement study aimed to visualize postoperative outcome data to allow anesthesiologists to reflect on their care and compare their performance with their peers.MethodsThe postoperative follow-up registry contains nurse-reported postoperative outcomes, including opioid and antiemetic administration in the postanesthetic care unit (PACU), and family-reported outcomes, including pain, nausea, and vomiting, within 24 hours post discharge. Dashboards were iteratively co-designed with 5 anesthesiologists, and a department-wide usability survey gathered anesthesiologists' feedback on the dashboards, allowing further design improvements. A final dashboard version has been deployed, with data updated weekly.ResultsThe dashboard contains three sections: (1) 24-hour outcomes, (2) PACU outcomes, and (3) a practice profile containing individual anesthesiologist's case mix, grouped by age groups, sex, and surgical service. At the time of evaluation, the dashboard included 24-hour data from 7877 cases collected from September 2020 to February 2023 and PACU data from 8716 cases collected from April 2021 to February 2023. The co-design process and usability evaluation indicated that anesthesiologists preferred simpler designs for data summaries but also required the ability to explore details of specific outcomes and cases if needed. Anesthesiologists considered security and confidentiality to be key features of the design and most deemed the dashboard information useful and potentially beneficial for their practice.ConclusionsWe designed and deployed a dynamic, personalized dashboard for anesthesiologists to review their outpatients' short-term postoperative outcomes. This dashboard facilitates personal reflection on individual practice in the context of peer and departmental performance and, hence, the opportunity to evaluate iterative practice changes. Further work is required to establish their effect on improving individual and department performance and patient outcomes.

Project description:Inflammatory bowel disease (IBD) is associated with an increased risk of colorectal cancer (CRC) compared to patients without IBD. There is a lack of population-based data evaluating the in-patient surgical outcomes of CRC in IBD patients. We sought to compare the hospital outcomes of CRC surgery between patients with and without IBD.We used the National Inpatient Sample (2008-2012) and Nationwide Readmissions Database (NRD, 2013) and selected all adult patients (age ?18 years) with ulcerative colitis (UC) or Crohn's disease (CD) who underwent CRC surgery. Multivariate analysis for in-patient outcomes of postoperative complications, health-care resource utilization, readmission rate, and mortality were performed.A total of 397,847 patients underwent CRC surgery from 2008 to 2012, of which 0.8% (3,242) had IBD. Compared to CRC in non-IBD patients, CRC in IBD patients had longer length of stay (adjusted coefficient (AC) 0.86 days, 95% confidence interval (CI): 0.42, 1.30), more likely developed postoperative complications (adjusted odds ratio (AOR) 1.26, 95% CI: 1.06, 1.50), including postoperative infection (AOR 1.69, 95% CI: 1.20, 2.38) and deep vein thrombosis (AOR 2.42, 95% CI: 1.36, 4.28), and more frequently required blood transfusion (AOR 1.59, 95% CI: 1.30, 1.94). CRC in IBD patients was more likely to be readmitted within 30 days (AOR 1.44, 95% CI: 1.01, 2.04).At a population level, IBD adversely impacts outcomes at the time of CRC surgery.
