How Would You Treat This Patient Hospitalized With Community-Acquired Pneumonia? : Grand Rounds Discussion From Beth Israel Deaconess Medical Center.

Community-acquired pneumonia is a major cause of morbidity and mortality in the United States, leading to 1.5 million hospitalizations and at least 200 000 deaths annually. The 2019 American Thoracic Society/Infectious Diseases Society of America clinical practice guideline on diagnosis and treatment of adults with community-acquired pneumonia provides an evidence-based overview of this common illness. Here, 2 experts, a general internist who served as the co-primary author of the guidelines and a pulmonary and critical care physician, debate the management of a patient hospitalized with community-acquired pneumonia. They discuss disease severity stratification methods, whether to use adjunctive corticosteroids, and when to prescribe empirical treatment for multidrug-resistant organisms such as methicillin-resistant Staphylococcus aureus and Pseudomonas aeruginosa.

Community-acquired Pneumonia Guideline Recommendations-Impact of a Consensus-based Process versus Systematic Reviews.

BACKGROUND: The American Thoracic Society (ATS)/Infectious Diseases Society of America (IDSA) Community-acquired Pneumonia (CAP) guidelines were developed using systematic reviews to inform every recommendation, as suggested by the Institute of Medicine Standards for Trustworthy Guidelines. Recent studies suggest that an expert consensus-based approach, called the Convergence of Opinion on Recommendations and Evidence (CORE) process, can produce recommendations that are concordant with recommendations informed by systematic reviews. PURPOSE: The goal of the study was to evaluate the efficacy of the CORE process had it been used to develop the ATS/IDSA CAP guidelines. METHODS: Experts in CAP who were not on the guideline panel and had no knowledge of the guideline's systematic reviews or recommendations were recruited to participate in the CORE process, addressing the same questions asked by the guideline panel. Recommendations derived from the CORE process were compared to the guideline recommendations. Concordance of the course of action, strength of recommendation, and quality of evidence were determined. RESULTS: Using a threshold of 70% of experts selecting the same course of action to make a recommendation, the CORE process yielded a recommendation for 20 of 31 (65%) questions. Among the 20 CORE-derived recommendations, 19 (95%) were concordant with the guideline recommendations (kappa agreement 0.88, 95% CI .64-1.00). There was less agreement among the strength of recommendations (58%) and quality of evidence (42%). CONCLUSIONS: If the CORE process had been used, 11 systematic reviews would have been necessary rather than 31, with minimal impact on the recommended courses of action.

Wireless versus routine physiologic monitoring after cesarean delivery to reduce maternal morbidity and mortality in a resource-limited setting: protocol of type 2 hybrid effectiveness-implementation study.

BACKGROUND: Women in sub-Saharan Africa have the highest rates of morbidity and mortality during childbirth globally. Despite increases in facility-based childbirth, gaps in quality of care at facilities have limited reductions in maternal deaths. Infrequent physiologic monitoring of women around childbirth is a major gap in care that leads to delays in life-saving interventions for women experiencing complications. METHODS: We will conduct a type-2 hybrid effectiveness-implementation study over 12 months to evaluate using a wireless physiologic monitoring system to detect and alert clinicians of abnormal vital signs in women for 24 h after undergoing emergency cesarean delivery at a tertiary care facility in Uganda. We will provide physiologic data (heart rate, respiratory rate, temperature and blood pressure) to clinicians via a smartphone-based application with alert notifications if monitored women develop predefined abnormalities in monitored physiologic signs. We will alternate two-week intervention and control time periods where women and clinicians use the wireless monitoring system during intervention periods and current standard of care (i.e., manual vital sign measurement when clinically indicated) during control periods. Our primary outcome for effectiveness is a composite of severe maternal outcomes per World Health Organization criteria (e.g. death, cardiac arrest, jaundice, shock, prolonged unconsciousness, paralysis, hysterectomy). Secondary outcomes include maternal mortality rate, and case fatality rates for postpartum hemorrhage, hypertensive disorders, and sepsis. We will use the RE-AIM implementation framework to measure implementation metrics of the wireless physiologic system including Reach (proportion of eligible women monitored, length of time women monitored), Efficacy (proportion of women with monitoring according to Uganda Ministry of Health guidelines, number of appropriate alerts sent), Adoption (proportion of clinicians utilizing physiologic data per shift, clinical actions in response to alerts), Implementation (fidelity to monitoring protocol), Maintenance (sustainability of implementation over time). We will also perform in-depth qualitative interviews with up to 30 women and 30 clinicians participating in the study. DISCUSSION: This is the first hybrid-effectiveness study of wireless physiologic monitoring in an obstetric population. This study offers insights into use of wireless monitoring systems in low resource-settings, as well as normal and abnormal physiologic parameters among women delivering by cesarean.

The effectiveness of post-discharge navigation added to an inpatient addiction consultation for patients with substance use disorder; a randomized controlled trial.

Background: It is unknown whether post-discharge navigation enhances the impact of hospital-initiated addiction care. This study tested the incremental benefit of telephonic linkage to a post-discharge navigator for patients who received an addiction consultation during hospitalization. Methods: A two-arm, randomized controlled trial of 395 hospitalized adults with substance use disorder who received an addiction consultation. The intervention group received post-discharge phone calls from a navigator to review the recommended treatment plan and address barriers to engagement on days 3, 7, 14, and 21. The primary outcome was days of alcohol or drug use in the past 30 assessed by Timeline Follow-back at 1 month. Results: Follow-up assessment completion rates were 46% at 1 month, and 41%, at 2 months. At baseline, intervention and control groups did not differ in substance use patterns; 45% reported primary alcohol use, 43% drugs, and 12% both. Heroin was the most common drug. At baseline, mean days of past 30-day alcohol or drug use were 13.6 in the intervention and 14.9 in the control group. The median number of navigation calls completed was 3 out of 4. At 1 month, both groups reported less use (decrease of 4.8 in intervention vs. 4.2 days in control group, p = 0.49). There were no differences between groups at 2 months. Compared to controls, participants who received all four calls had a greater decrease in use with a mean 8.6 days decrease from baseline (difference of 4.4 days, p = 0.0009). Conclusion: Post-discharge telephonic patient navigation did not further improve substance use outcomes following addiction consultation.

Baseline Factors Associated with Mortality in Patients Who Engaged in Buprenorphine Treatment for Opioid Use Disorder: a Cohort Study.

BACKGROUND: Opioid agonist therapy (OAT) has been shown to reduce mortality in patients with opioid use disorder (OUD), yet mortality in individuals receiving OAT remains higher than in an age- and gender-matched population. OBJECTIVE: To identify baseline risk factors in patients who engaged in buprenorphine treatment that are associated with this elevated risk of death. DESIGN: We performed a retrospective cohort study from January 1, 2007, to December 31, 2018, using a centralized clinical data registry within a multi-hospital health system in Boston, MA, USA. PARTICIPANTS: All adult patients who had ≥ 2 consecutive encounters with sublingual buprenorphine on the active medication list from January 1, 2007, to December 31, 2018. MAIN MEASURES: We abstracted several sociodemographic, clinical, and healthcare use characteristics from the clinical data registry. The primary outcome was all-cause mortality and the secondary outcome was opioid overdose-related mortality. We performed multivariable cox regression to identify baseline characteristics independently associated with these outcomes. KEY RESULTS: Of 5948 patients in the cohort, the majority were white (80.7%) and male (59.7%), with a mean age of 38.2 years. The all-cause mortality rate was 24.0 deaths per 1000 person-years. Baseline characteristics independently associated with an increased hazard of all-cause mortality included homelessness (adjusted hazard ratio [aHR] = 1.39; 95% confidence interval [CI] = 1.09, 1.78), an opioid on the active medication list (aHR = 1.28; 95% CI = 1.08, 1.52), and entry into the cohort during an inpatient hospitalization (aHR = 1.43; 95% CI = 1.18, 1.73). Homelessness was also associated with an increased hazard of opioid overdose-related mortality (aHR = 1.77; 95% CI = 1.25, 2.50). CONCLUSIONS: We identified several novel and potentially modifiable predictors of mortality among patients engaging in buprenorphine treatment who remain at an increased risk of death compared with the general population. Understanding these risk factors can assist healthcare providers in risk stratification and inform the design of targeted interventions to improve outcomes in a high-risk patient population.

Update in adult community-acquired pneumonia: key points from the new American Thoracic Society/Infectious Diseases Society of America 2019 guideline.

PURPOSE OF REVIEW: The American Thoracic Society and Infectious Diseases Society of America recently released their joint guideline for the diagnosis and treatment of adults with community-acquired pneumonia (CAP). The co-chairs of the guideline committee provide a summary of the guideline process, key recommendations from the new guideline and future directions for CAP research. RECENT FINDINGS: The guideline committee included 14 experts from the two societies. Sixteen questions for the guideline were selected using the PICO format. The GRADE approach was utilized to review the available evidence and generate recommendations. The recommendations included expanded microbiological testing for patients suspected of drug-resistant infections, empiric first-line therapy recommendations for outpatients and inpatients including use of beta-lactam monotherapy for uncomplicated outpatients, elimination of healthcare-associated pneumonia as a treatment category, and not recommending corticosteroids as routine adjunct therapy. SUMMARY: CAP is a major cause of morbidity and mortality. Effective antibiotic therapy is available and remains largely empirical. New diagnostic tests and treatment options are emerging and will lead to guideline updates in the future.

Diagnosis and Treatment of Adults with Community-acquired Pneumonia. An Official Clinical Practice Guideline of the American Thoracic Society and Infectious Diseases Society of America.

Background: This document provides evidence-based clinical practice guidelines on the management of adult patients with community-acquired pneumonia.Methods: A multidisciplinary panel conducted pragmatic systematic reviews of the relevant research and applied Grading of Recommendations, Assessment, Development, and Evaluation methodology for clinical recommendations.Results: The panel addressed 16 specific areas for recommendations spanning questions of diagnostic testing, determination of site of care, selection of initial empiric antibiotic therapy, and subsequent management decisions. Although some recommendations remain unchanged from the 2007 guideline, the availability of results from new therapeutic trials and epidemiological investigations led to revised recommendations for empiric treatment strategies and additional management decisions.Conclusions: The panel formulated and provided the rationale for recommendations on selected diagnostic and treatment strategies for adult patients with community-acquired pneumonia.

Effect of Integrating Substance Use Disorder Treatment into Primary Care on Inpatient and Emergency Department Utilization.

BACKGROUND: Components of substance use disorder (SUD) treatment have been shown to reduce inpatient and emergency department (ED) utilization. However, integrated treatment using pharmacotherapy and recovery coaches in primary care has not been studied. OBJECTIVE: To determine whether integrated addiction treatment in primary care reduces inpatient and ED utilization and improves outpatient engagement. DESIGN: A retrospective cohort study comparing patients in practices with and without integrated addiction treatment including pharmacotherapy and recovery coaching during a staggered roll-out period. PARTICIPANTS: A propensity score matched sample of 2706 adult primary care patients (1353 matched pairs from intervention and control practices) with a SUD diagnosis code, excluding cannabis or tobacco only, matched on baseline utilization. INTERVENTION: A multi-modal strategy that included forming interdisciplinary teams of local champions, access to addiction pharmacotherapy, counseling, and recovery coaching. Control practices could refer patients to an addiction treatment clinic offering pharmacotherapy and behavioral interventions. MAIN MEASURES: The number of inpatient admissions, hospital bed days, ED visits, and primary care visits. KEY RESULTS: During the follow-up period, there were fewer inpatient days among the intervention group (997 vs. 1096 days with a mean difference of 7.3 days per 100 patients, p = 0.03). The mean number of ED visits was lower for the intervention group (36.2 visits vs. 42.9 per 100 patients, p = 0.005). There was no difference in the mean number of hospitalizations. The mean number of primary care visits was higher for the intervention group (317 visits vs. 270 visits per 100 patients, p < 0.001). Intervention practices had a greater increase in buprenorphine and naltrexone prescribing. CONCLUSIONS: In a non-randomized retrospective cohort study, integrated addiction pharmacotherapy and recovery coaching in primary care resulted in fewer hospital days and ED visits for patients with SUD compared to similarly matched patients receiving care in practices without these services.

Patterns of multimorbidity associated with 30-day readmission: a multinational study.

BACKGROUND: Multimorbidity is associated with higher healthcare utilization; however, data exploring its association with readmission are scarce. We aimed to investigate which most important patterns of multimorbidity are associated with 30-day readmission. METHODS: We used a multinational retrospective cohort of 126,828 medical inpatients with multimorbidity defined as ≥2 chronic diseases. The primary and secondary outcomes were 30-day potentially avoidable readmission (PAR) and 30-day all-cause readmission (ACR), respectively. Only chronic diseases were included in the analyses. We presented the OR for readmission according to the number of diseases or body systems involved, and the combinations of diseases categories with the highest OR for readmission. RESULTS: Multimorbidity severity, assessed as number of chronic diseases or body systems involved, was strongly associated with PAR, and to a lesser extend with ACR. The strength of association steadily and linearly increased with each additional disease or body system involved. Patients with four body systems involved or nine diseases already had a more than doubled odds for PAR (OR 2.35, 95%CI 2.15-2.57, and OR 2.25, 95%CI 2.05-2.48, respectively). The combinations of diseases categories that were most strongly associated with PAR and ACR were chronic kidney disease with liver disease or chronic ulcer of skin, and hematological malignancy with esophageal disorders or mood disorders, respectively. CONCLUSIONS: Readmission was associated with the number of chronic diseases or body systems involved and with specific combinations of diseases categories. The number of body systems involved may be a particularly interesting measure of the risk for readmission in multimorbid patients.

Preventability of Early Versus Late Hospital Readmissions in a National Cohort of General Medicine Patients.

Background: Many experts believe that hospitals with more frequent readmissions provide lower-quality care, but little is known about how the preventability of readmissions might change over the postdischarge time frame. Objective: To determine whether readmissions within 7 days of discharge differ from those between 8 and 30 days after discharge with respect to preventability. Design: Prospective cohort study. Setting: 10 academic medical centers in the United States. Patients: 822 adults readmitted to a general medicine service. Measurements: For each readmission, 2 site-specific physician adjudicators used a structured survey instrument to determine whether it was preventable and measured other characteristics. Results: Overall, 36.2% of early readmissions versus 23.0% of late readmissions were preventable (median risk difference, 13.0 percentage points [interquartile range, 5.5 to 26.4 percentage points]). Hospitals were identified as better locations for preventing early readmissions (47.2% vs. 25.5%; median risk difference, 22.8 percentage points [interquartile range, 17.9 to 31.8 percentage points]), whereas outpatient clinics (15.2% vs. 6.6%; median risk difference, 10.0 percentage points [interquartile range, 4.6 to 12.2 percentage points]) and home (19.4% vs. 14.0%; median risk difference, 5.6 percentage points [interquartile range, -6.1 to 17.1 percentage points]) were better for preventing late readmissions. Limitation: Physician adjudicators were not blinded to readmission timing, community hospitals were not included in the study, and readmissions to nonstudy hospitals were not included in the results. Conclusion: Early readmissions were more likely to be preventable and amenable to hospital-based interventions. Late readmissions were less likely to be preventable and were more amenable to ambulatory and home-based interventions. Primary Funding Source: Association of American Medical Colleges.

Ischemic Stroke Transfer Patterns in the Northeast United States.

BACKGROUND: Little is known about how hospitals are connected in the transfer of ischemic stroke (IS) patients. We aimed to describe differences in characteristics of transferred versus nontransferred patients and between transferring and receiving hospitals in the Northeastern United States, and to describe changes over time. METHODS: We used Medicare claims data, and a subset linked with the Get with the Guidelines-Stroke registry from 2007 to 2011. Receiving hospitals were those with annual IS volume greater than or equal to 120 and greater than or equal to 15% received as transfers, and transferring hospitals were nonaccepting hospitals that transferred greater than or equal to 15% of their total (ED plus inpatient) IS patient discharges. A transferring-to-receiving hospital connection was identified if greater than or equal to 5 patients per year were shared. ArcGIS 10.3.1 was used for network visualization. RESULTS: Among 177,270 admissions to 402 Northeast hospitals, 6906 (3.9%) patients were transferred. Transferred patients were younger with more severe strokes (78 versus 81 years, P < .001; National Institutes of Health Stroke Severity 7 versus 5, P < .001), and were as likely to receive tissue plasminogen activator as nontransferred (P = .29). From 2007 to 2011, there were more patients transferred (960 [3%] to 1777 [6%], P < .001), and more transferring hospitals (46 [12%] to 91 [24%], P < .001), and receiving hospitals (6 [2%] to 16 [4%], P < .001). Most transferring hospitals were exclusively connected to a single receiving hospital. CONCLUSIONS: From 2007 to 2011, hospitals in the United States Northeast became more connected in the care of IS patients, with increasing patient transfers and hospital connections. Yet most hospitals remained unconnected. Further characterization of this transfer network will be important for understanding and improving regional stroke systems of care.

Increasing sex differences in the use of cardiac resynchronization therapy with or without implantable cardioverter-defibrillator.

AIMS: Previous studies have identified sex disparities in the use of cardiac resynchronization therapy (CRT) and implantable cardioverter defibrillators (ICD), although the basis of underutilization in women remains poorly understood. The aim of this study was to assess sex differences in patterns of CRT use with our without ICD. METHODS AND RESULTS: In this cross-sectional study using the National Inpatient Sample database we identified 311 009 patients undergoing CRT implantation in the United States between 2006 and 2012. Demographic and clinical characteristics were compared between men and women undergoing CRT implantation, with special attention to clinical predictors of left ventricular reverse remodelling (CRT response, score range: 0-4) and reduced ICD efficacy (score range: 0-7). When compared to men, women undergoing CRT implantation were significantly more likely to have ≥ 3 predictors of CRT response (47.3 vs. 33.2%, P < 0.001) and less likely to have ≥3 predictors of reduced ICD efficacy (27.0 vs. 37.3%, P < 0.001). Despite this, men were significantly more likely to undergo CRT with ICD (CRT-D) as the type of CRT (88.6 vs. 80.1% of all CRT implants). Compared to those with the greatest likelihood of CRT response (score ≥ 3), those with the least likelihood of CRT response had a significant decreased odds of CRT-D implant (adj odds ratio 0.27 [0.24-0.31], P < 0.001), with a greater decreased odds in women compared to men (P, for sex interaction <0.001). The difference in the % of CRT-D implant in men vs. women increased over the study period (P, sex Δ time trend = 0.012). CONCLUSION: In this large, contemporary cohort, sex differences in CRT-D implantation were inversely related to predicted CRT efficacy and have increased over time. Future efforts to narrow the gap in CRT-D implantation in men and women may help better align device selection with those most likely to benefit.

National Trends in the Use of Cardiac Resynchronization Therapy With or Without Implantable Cardioverter-Defibrillator.

BACKGROUND: Candidates for cardiac resynchronization therapy (CRT) receive either a biventricular pacemaker or a biventricular pacemaker with an implantable cardioverter-defibrillator (CRT-D). Optimal device selection remains challenging because the benefit of implantable cardioverter-defibrillator therapy may not be uniform, particularly in patients at competing risk of nonsudden death. METHODS AND RESULTS: In this serial cross-sectional study using the National Inpatient Sample database, we identified 311,086 admissions associated with CRT implant between 2006 to 2012. CRT-D was the most common device type (86.1%), including in patients ≥ 75 years of age with ≥ 5 Elixhauser comorbidities (75.5%). Multivariate predictors of CRT-D implant included demographic, clinical, and geographic factors: prior ventricular arrhythmia (rate ratio [RR], 1.14; 95% CI, 1.13-1.14), ischemic heart disease (RR, 1.11; 95% CI, 1.10-1.11), male sex (RR, 1.10; 95% CI, 1.09-1.10), black race (RR, 1.06; 95% CI: 1.04-1.07), and Northeast geographic region (RR, 1.06; 95% CI, 1.04-1.09). There was significant interhospital variation in the use of CRT-D (10-90 percentile range, 72.9%-98.0% CRT-D). CONCLUSIONS: The majority of patients in this contemporary US cohort underwent implantation of CRT-D. Predictors of CRT-D implant included demographic, clinical, and geographic factors. In patient subgroups predicted to have an attenuated benefit from implantable cardioverter-defibrillator therapy (older adults with multiple comorbidities), CRT-D remained the dominant device type. An improved understanding of the determinants of device selection may aid in decision making and ultimately better align patient risk with device benefit at the time of CRT implantation.

Personal and Professional Characteristics of U.S. Dual-Boarded Critical Care Cardiologists in 2015.

OBJECTIVES: Evaluate the characteristics of U.S. physicians who are board certified in cardiology and critical care medicine ("dual-boarded cardiologists"). DESIGN: Retrospective cross-sectional study using a comprehensive database of licensed U.S. physicians linked to Medicare claims. SETTING: The United States. SUBJECTS: Dual-boarded cardiologists. MEASUREMENTS AND MAIN RESULTS: We used a comprehensive physician database to identify all physicians who were board certified in cardiology and critical care medicine before July 2015. We assessed physicians' characteristics and compared dual-boarded cardiologists with and without active board certification in critical care medicine and estimated the maximum proportion of 2014 Medicare Cardiac ICU admissions treated by dual-boarded cardiologists. Among 473 dual-boarded cardiologists, 16 (3.4%) were women; 468 (99%) and 85 (18%) maintained active board certification in cardiology and critical care medicine, respectively. Overall, 98 dual-boarded cardiologists (21%) submitted 1,215 total claims for critical care services in 2014. Compared to dual-boarded cardiologists without active board certification in critical care medicine, those with active certification had more publications (median publications: 6.5 vs 3.0; p = 0.002), were more likely to be professors (22.3% vs 9.5%; p = 0.003), and were more likely to bill Medicare for critical care services (29% vs 17.8%; p = 0.002). We estimated that no more than 0.47% of all 2014 Medicare Cardiac ICU admissions were treated by a dual-boarded cardiologist. CONCLUSIONS: Dual-boarded cardiologists appear to deliver a small proportion of all Cardiac ICU services received by Medicare beneficiaries. Optimizing the modern Cardiac ICU workforce will require greater efforts to promote and support the training of dual-boarded cardiologists.

Prevalence and correlates of MRSA and MSSA nasal carriage at a Ugandan regional referral hospital.

Background: Despite increasing antimicrobial resistance globally, data are lacking on prevalence and factors associated with Staphylococcus aureus (SA) and MRSA carriage in resource-limited settings. Objectives: To determine the prevalence of SA and MRSA nasal carriage and factors associated with carriage among Ugandan regional referral hospital patients. Methods: We enrolled a cross-section of 500 adults, sampling anterior nares for SA and MRSA carriage using Cepheid Xpert SA Nasal Complete. Results: Mean age was 37 years; 321 (64%) were female and 166 (33%) were HIV infected. Overall, 316 (63%) reported risk factors for invasive SA infection; 368 (74%) reported current antibiotic use. SA was detected in 29% and MRSA in 2.8%. MRSA and MSSA carriers were less likely than SA non-carriers to be female (50% and 56% versus 68%, P = 0.03) or to have recently used ß-lactam antibiotics (43% and 65% versus 73%, P = 0.01). MRSA carriers were more likely to have open wounds than MSSA carriers and SA non-carriers (71% versus 27% and 40%, P = 0.001) and contact with pigs (21% versus 2% and 6%, P = 0.008). MRSA carriage ranged from 0% of HIV clinic participants to 8% of inpatient surgical ward participants ( P = 0.01). In multivariable logistic regression analysis, male sex was independently associated with SA carriage (OR 1.68, 95% CI 1.12-2.53, P = 0.01) and recent ß-lactam antibiotic use was associated with reduced odds of SA carriage (OR 0.61, 95% CI 0.38-0.97, P = 0.04). Conclusions: MRSA nasal carriage prevalence was low and associated with pig contact, open wounds and surgical ward admission, but not with HIV infection.

The HOSPITAL Score Predicts Potentially Preventable 30-Day Readmissions in Conditions Targeted by the Hospital Readmissions Reduction Program.

BACKGROUND/OBJECTIVES: New tools to accurately identify potentially preventable 30-day readmissions are needed. The HOSPITAL score has been internationally validated for medical inpatients, but its performance in select conditions targeted by the Hospital Readmission Reduction Program (HRRP) is unknown. DESIGN: Retrospective cohort study. SETTING: Six geographically diverse medical centers. PARTICIPANTS/EXPOSURES: All consecutive adult medical patients discharged alive in 2011 with 1 of the 4 medical conditions targeted by the HRRP (acute myocardial infarction, chronic obstructive pulmonary disease, pneumonia, and heart failure) were included. Potentially preventable 30-day readmissions were identified using the SQLape algorithm. The HOSPITAL score was calculated for all patients. MEASUREMENTS: A multivariable logistic regression model accounting for hospital effects was used to evaluate the accuracy (Brier score), discrimination (c-statistic), and calibration (Pearson goodness-of-fit) of the HOSPITAL score for each 4 medical conditions. RESULTS: Among the 9181 patients included, the overall 30-day potentially preventable readmission rate was 13.6%. Across all 4 diagnoses, the HOSPITAL score had very good accuracy (Brier score of 0.11), good discrimination (c-statistic of 0.68), and excellent calibration (Hosmer-Lemeshow goodness-of-fit test, P=0.77). Within each diagnosis, performance was similar. In sensitivity analyses, performance was similar for all readmissions (not just potentially preventable) and when restricted to patients age 65 and above. CONCLUSIONS: The HOSPITAL score identifies a high-risk cohort for potentially preventable readmissions in a variety of practice settings, including conditions targeted by the HRRP. It may be a valuable tool when included in interventions to reduce readmissions within or across these conditions.

Inpatient Addiction Consultation for Hospitalized Patients Increases Post-Discharge Abstinence and Reduces Addiction Severity.

BACKGROUND: Alcohol and drug use results in substantial morbidity, mortality, and cost. Individuals with alcohol and drug use disorders are overrepresented in general medical settings. Hospital-based interventions offer an opportunity to engage with a vulnerable population that may not otherwise seek treatment. OBJECTIVE: To determine whether inpatient addiction consultation improves substance use outcomes 1 month after discharge. DESIGN: Prospective quasi-experimental evaluation comparing 30-day post-discharge outcomes between participants who were and were not seen by an addiction consult team during hospitalization at an urban academic hospital. PARTICIPANTS: Three hundred ninety-nine hospitalized adults who screened as high risk for having an alcohol or drug use disorder or who were clinically identified by the primary nurse as having a substance use disorder. INTERVENTION: Addiction consultation from a multidisciplinary specialty team offering pharmacotherapy initiation, motivational counseling, treatment planning, and direct linkage to ongoing addiction treatment. MAIN MEASURES: Addiction Severity Index (ASI) composite score for alcohol and drug use and self-reported abstinence at 30 days post-discharge. Secondary outcomes included 90-day substance use measures and self-reported hospital and ED utilization. KEY RESULTS: Among 265 participants with 30-day follow-up, a greater reduction in the ASI composite score for drug or alcohol use was seen in the intervention group than in the control group (mean ASI-alcohol decreased by 0.24 vs. 0.08, p < 0.001; mean ASI-drug decreased by 0.05 vs. 0.02, p = 0.003.) There was also a greater increase in the number of days of abstinence in the intervention group versus the control group (+12.7 days vs. +5.6, p < 0.001). The differences in ASI-alcohol, ASI-drug, and days abstinent all remained statistically significant after controlling for age, gender, employment status, smoking status, and baseline addiction severity (p = 0.018, 0.018, and 0.02, respectively). In a sensitivity analysis, assuming that patients who were lost to follow-up had no change from baseline severity, the differences remained statistically significant. CONCLUSIONS: In a non-randomized cohort of medical inpatients, addiction consultation reduced addiction severity for alcohol and drug use and increased the number of days of abstinence in the first month after hospital discharge.

Using a Self-Reported Global Health Measure to Identify Patients at High Risk for Future Healthcare Utilization.

BACKGROUND: Research studies have shown that patient-reported outcome measures (PROMs) that assess global health are helpful for predicting health care utilization, but less evidence exists that collection of PROMs in routine care can identify patients with high health care needs. OBJECTIVE: To investigate the association between the PROMIS Global Health (PGH) scores and subsequent health care utilization among patients in a large accountable care organization (ACO). DESIGN: Retrospective cohort study of individuals in the Partners HealthCare ACO who completed at least one PGH during a primary care visit. PARTICIPANTS: A total of 2639 individuals who completed at least one PGH and who also had 12 months of ACO membership and/or claims data prior to the PROM completion and at least one month of claims data post-PGH completion. MAIN MEASURES: The main outcomes were the rates of emergency department (ED) visits and hospitalizations by quartile of PGH physical and mental health scores. We also compared the predictive accuracy of administrative data models with and without the PGH scores to identify the highest utilizers. KEY RESULTS: The group with the worst (lowest) physical and mental health scores had significantly higher rates of hospitalization (RR 5.14, 95% CI 2.37, 11.15; and 2.27, 95% CI 1.06, 4.85, respectively) than those with higher scores. After adjustment for demographic and clinical factors, only the group with lower physical health scores had higher rates of hospitalization (RR 3.15, 95% CI 1.30, 7.90). The addition of the physical health subscore to administrative data increased the sensitivity to detect the top 5% of hospital utilizers compared with administrative data alone (44.0% vs. 36.0% respectively). CONCLUSIONS: Worse self-reported physical health, measured during routine primary care, is associated with significantly higher rates of hospitalization. It is not associated with increased rates of ED visits. Self-reported physical health modestly increases the sensitivity to detect the highest hospital utilizers.

Short, frequent, 5-days-per-week, in-center hemodialysis versus 3-days-per week treatment: a randomized crossover pilot trial through the Midwest Pediatric Nephrology Consortium.

BACKGROUND: No controlled trials in children with end-stage kidney disease have assessed the benefits of more frequently administered hemodialysis (HD). METHODS: We conducted a multicenter, crossover pilot trial to determine if short, more frequent (5 days per week) in-center HD was feasible and associated with improvements in blood pressure compared with three conventional HD treatments per week. Because adult studies have not controlled for the weekly duration of dialysis, we fixed the total treatment time at 12 h a week of dialysis during two 3-month study periods; only frequency varied from 5 to 3 days per week between study periods. RESULTS: Eight children (median age 16.7 years) consented at three children's hospitals. The prespecified primary composite outcome was a sustained 10% decrease in systolic blood pressure and/or a decrease in antihypertensive medications relative to each study period's baseline. Among the six patients completing both study periods, five (83.3%) experienced the primary outcome during HD performed 5 days per week but not 3 days per week; one of the six (16.7%) achieved that outcome during 3-day but not 5-day (p = 0.22) per week HD. During 5-day HD, all patients had significantly more treatments during which their pre-HD systolic (p = 0.01) or diastolic (p = 0.01) blood pressure was 10% lower than baseline. CONCLUSIONS: We observed that more frequent HD sessions per week was feasible and associated with improved blood pressure control, but barriers to changing thrice-weekly standard of care include financial reimbursement and the time demands associated with more frequent treatments.
