Health Within Reach-a Patient-Centered Intervention to Increase Hepatitis B Screening Among Asian Americans: a Randomized Clinical Trial.

BACKGROUND: There are few studies to date of interventions to increase viral hepatitis screening among Asian Americans, who have high rates of chronic hepatitis B (HBV) infection. OBJECTIVE: To develop, implement, and test the efficacy of a mobile application (Hepatitis App) delivered in four languages to increase HBV screening among Asian Americans. DESIGN: Cluster-randomized clinical trial. PARTICIPANTS: Four hundred fifty-two Asian American patients ≥ 18 years of age, who had no prior HBV testing, and received primary care within two healthcare systems in San Francisco, CA. INTERVENTIONS: The intervention group received the Hepatitis App, delivering interactive video education on viral hepatitis in English, Cantonese, Mandarin, or Vietnamese and a provider printout (Provider Alert) and Provider Panel Notification. The comparison group received a mobile application delivering nutrition and physical activity education and Provider Panel Notification. MAIN MEASURES: Primary outcomes were patient-provider discussion about HBV and documentation of a HBV screening test within 3 months post-intervention. Secondary outcome was documentation of an order for a HBV screening test. KEY RESULTS: Participants had a mean age of 57 years and were 64% female, 80% foreign-born, and 44% with limited English fluency. At post-visit, over 80% of intervention participants reported they liked using the Hepatitis App. At 3-month follow-up, the intervention group was more likely than the comparison group (all P < 0.001) to have discussed HBV with their provider (70% vs.16%), have a HBV test ordered (44% vs.10%), and receive a HBV test (38% vs.8%). In multivariable analyses, the intervention odds ratio for HBV test ordering was 7.6 (95% CI: 3.9, 14.8) and test receipt was 7.5 (95% CI: 3.6, 15.5). CONCLUSIONS: A multi-lingual educational intervention using a mobile application in primary care clinics was well received by Asian American patients, enhanced patient-provider communication about HBV, and increased HBV screening. Technology can improve healthcare quality among Asian Americans. TRIAL REGISTRATION: ClinicalTrials.gov NCT02139722 ( https://clinicaltrials.gov/ct2/show/NCT02139722 ).

High perceived social support and hospital readmissions in an older multi-ethnic, limited English proficiency, safety-net population.

BACKGROUND: Early readmission amongst older safety-net hospitalized adults is costly. Interventions to prevent early readmission have had mixed success. The role of perceived social support is unclear. We examined the association of perceived social support in 30-day readmission or death in older adults admitted to a safety-net hospital. METHODS: This is an observational cohort study derived from the Support From Hospital to Home for Elders (SHHE) trial. Participants were community-dwelling English, Spanish and Chinese speaking older adults admitted to medicine wards at an urban safety-net hospital in San Francisco. We assessed perceived social support using the Multidimensional Scale of Perceived Social Support (MSPSS). We defined high social support as the highest quartile of MSPSS. We ascertained 30-day readmission and mortality based on a combination of participant self-report, hospital and death records. We used multiple/multivariable logistic regression to adjust for patient demographics, health status, and health behaviors. We tested for whether race/ethnicity modified the effect high social support had on 30-day readmission or death by including a race-social support interaction term. RESULTS: Participants (n = 674) had mean age of 66.2 (SD 9.0), with 18.8% White, 24.8% Black, 31.9% Asian, and 19.3% Latino. The 30-day readmission or death rate was 15.0%. Those with high social support had half the odds of readmission or death than those with low social support (OR = 0.47, 95% CI 0.26-0.88). Interaction analyses revealed race modified this association; higher social support was protective against readmission or death among minorities (AOR = 0.35, 95% CI 0.16-0.76) but increased likelihood of readmission or death among Whites (AOR = 3.7, 95% CI 1.07-12.9). CONCLUSION: In older safety-net patients nearing discharge, high perceived social support may protect against 30-day readmission or death among minorities. Assessing patients' social support may aid targeting of transitional care resources and intervention design. How perceived social support functions across racial/ethnic groups in health outcomes warrants further study. TRIAL REGISTRATION: NIH trials registry number ClinicalTrials.gov: NCT01221532 .

Clinician Perspectives on the Management of Abnormal Subcritical Tests in an Urban Academic Safety-Net Health Care System.

BACKGROUND: Missed or delayed follow-up of abnormal subcritical tests (tests that do not require immediate medical attention) can lead to poor patient outcomes. Safety-net health systems with limited resources and socially complex patients are vulnerable to safety gaps resulting from delayed management. Clinician perspectives to identify system challenges, vulnerable situations, and potential solutions were sought in focus groups. METHODS: Five semistructured focus groups were conducted in 2015 with purposefully sampled clinicians from radiology, hospital medicine, emergency medicine, risk management, and ambulatory care from an urban, academic, integrated, safety-net health system. Thematic analysis identified challenges of current management of abnormal subcritical tests, vulnerable situations, and solution characteristics. A total of 43 clinicians participated. RESULTS: Clinicians cited challenges in assigning responsibility for follow-up and identified tests pending at discharge and tests requiring delayed follow-up as vulnerable situations. The lack of tracking systems and missing contact information for patients and providers exacerbated these challenges. Proposed solution characteristics involved protocols to aid in assigning responsibility, reliable paths of communication, and systems to track the status of tests. Clinicians noted a strong desire for integration of the work flow and technology solutions into existing structures. CONCLUSION: In an urban safety-net setting, clinicians recommended outlining clear chains of responsibility and communication in the management of subcritical test results, and employing simple, integrated technological solutions that allow for tracking and management of tests. Existing test management solutions should be adapted to work within safety-net systems, which often have fewer resources and more complex patients and may function in the absence of integrated technology systems.

The Effect of a Care Transition Intervention on the Patient Experience of Older Multi-Lingual Adults in the Safety Net: Results of a Randomized Controlled Trial.

BACKGROUND: The Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS) and Care Transitions Measure (CTM-3) scores are patient experience measures used to determine hospital value-based purchasing reimbursement. Interventions to improve 30-day readmissions have met with mixed results, but less is known about their potential to improve the patient experience among older ethnically and linguistically diverse adults receiving care at safety-net hospitals. In this study, we assessed the effect of a nurse-led hospital-based care transition intervention on discharge-related patient experience in an older multilingual population of adults hospitalized at a safety-net hospital. METHODS: We randomized 700 inpatients aged 55 and older at an academic urban safety-net hospital. In addition to usual care, intervention participants received inpatient visits by a language-concordant study nurse and post-discharge phone calls from a language-concordant nurse practitioner to reinforce the care plan and to address acute complaints. We measured HCAHPS nursing, medication, and discharge communication domain scores and CTM-3 scores at 30 days after hospital discharge. RESULTS: Of 685 participants who survived to 30 days, 90 % (n = 616) completed follow-up interviews. The mean age was 66.2 years; over half (54.2 %) of the participants had cognitive impairment, and 33.8 % had moderate to severe depression. The majority (62.1 %) of interviews were conducted in English; 23.3 % were conducted in Chinese and 14.6 % in Spanish. Study nurses spent an average of 157 min with intervention participants. Between intervention and usual care participants, CTM-3 scores (80.5 % vs 78.5 %; p = 0.18) and HCAHPS discharge communication domain scores (74.8 % vs 68.7 %; p = 0.11) did not differ, nor did HCAHPS scores in medication (44.5 % vs 53.1 %; p = 0.13) and nursing domains (67.9 % vs 64.9 %; p = 0.43). When stratified by language, no significant differences were seen. CONCLUSION: An inpatient standalone transition-of-care intervention did not improve patient discharge experience. Older multi-lingual and cognitively impaired populations may require higher-intensity interventions post-hospitalization to improve discharge experience outcomes.

Hospitalization-Associated Disability in Adults Admitted to a Safety-Net Hospital.

BACKGROUND: Little is known about hospitalization-associated disability (HAD) in older adults who receive care in safety-net hospitals. OBJECTIVES: To describe HAD and to examine its association with age in adults aged 55 and older hospitalized in a safety-net hospital. DESIGN: Secondary post hoc analysis of a prospective cohort from a discharge intervention trial, the Support from Hospital to Home for Elders. SETTING: Medicine, cardiology, and neurology inpatient services of San Francisco General Hospital, a safety-net hospital. PARTICIPANTS: A total of 583 participants 55 and older who spoke English, Spanish, or Chinese. We determined the incidence of HAD 30 days post-hospitalization and ORs for HAD by age group. MEASUREMENTS: The outcome measure was death or HAD at 30 days after hospital discharge. HAD is defined as a new or additional disability in one or more activities of daily living (ADL) that is present at hospital discharge compared to baseline. Participants' functional status at baseline (2 weeks prior to admission) and 30 days post-discharge was ascertained by self-report of ADL function. RESULTS: Many participants (75.3 %) were functionally independent at baseline. By age group, HAD occurred as follows: 27.4 % in ages 55-59, 22.2 % in ages 60-64, 17.4 % in ages 65-69, 30.3 % in ages 70-79, and 61.7 % in ages 80 or older. Compared to the youngest group, only the adjusted OR for HAD in adults over 80 was significant, at 2.45 (95 % CI 1.17, 5.15). CONCLUSIONS: In adults at a safety-net hospital, HAD occurred in similar proportions among adults aged 55-59 and those aged 70-79, and was highest in the oldest adults, aged ≥ 80. In safety-net hospitals, interventions to reduce HAD among patients 70 years and older should consider expanding age criteria to adults as young as 55.

Support from hospital to home for elders: a randomized trial.

BACKGROUND: Hospitals are implementing discharge support programs to reduce readmissions, and these programs have had mixed success. OBJECTIVE: To examine whether a peridischarge, nurse-led intervention decreased emergency department (ED) visits or readmissions among ethnically and linguistically diverse older patients admitted to a safety-net hospital. DESIGN: Randomized, controlled trial using computer-generated randomization with 1:1 allocation, stratified by language. (Clinical Trials.gov: NCT01221532). SETTING: Publicly funded urban hospital in Northern California. PATIENTS: Hospitalized adults aged 55 years or older with anticipated discharge to the community who spoke English, Spanish, or Chinese (Mandarin or Cantonese). INTERVENTION: Usual care versus in-hospital, one-on-one, self-management education given by a dedicated language-concordant registered nurse combined with a telephone follow-up after discharge from a nurse practitioner. MEASUREMENTS: Staff blinded to the study groups determined ED visits or readmissions to any facility at 30, 90, and 180 days after initial hospital discharge using administrative data from several hospitals. RESULTS: There were 700 low-income, ethnically and linguistically diverse patients with a mean age of 66.2 years (SD, 9.0). The primary outcome of ED visits or readmissions did not differ between the intervention and usual care groups (hazard ratio, 1.26 [95% CI, 0.89 to 1.78] at 30 days, 1.21 [CI, 0.91 to 1.62] at 90 days, and 1.11 [CI, 0.86 to 1.43] at 180 days). LIMITATIONS: This study was done at a single acute-care hospital. There were fewer outcomes than expected, which may have caused the study to be underpowered. CONCLUSION: A nurse-led, in-hospital discharge support intervention did not show a reduction in readmissions or ED visits among diverse, low-income older adults at a safety-net hospital. Although wide CIs preclude firm conclusions, the intervention may have increased ED visits. Alternative readmission prevention strategies should be tested in this population.

Timeliness of abnormal screening and diagnostic mammography follow-up at facilities serving vulnerable women.

BACKGROUND: Whether timeliness of follow-up after abnormal mammography differs at facilities serving vulnerable populations, such as women with limited education or income, in rural areas, and racial/ethnic minorities is unknown. METHODS: We examined receipt of diagnostic evaluation after abnormal mammography using 1998-2006 Breast Cancer Surveillance Consortium-linked Medicare claims. We compared whether time to recommended breast imaging or biopsy depended on whether women attended facilities serving vulnerable populations. We characterized a facility by the proportion of mammograms performed on women with limited education or income, in rural areas, or racial/ethnic minorities. RESULTS: We analyzed 30,874 abnormal screening examinations recommended for follow-up imaging across 142 facilities and 10,049 abnormal diagnostic examinations recommended for biopsy across 114 facilities. Women at facilities serving populations with less education or more racial/ethnic minorities had lower rates of follow-up imaging (4%-5% difference, P<0.05), and women at facilities serving more rural and low-income populations had lower rates of biopsy (4%-5% difference, P<0.05). Women undergoing biopsy at facilities serving vulnerable populations had longer times until biopsy than those at facilities serving nonvulnerable populations (21.6 vs. 15.6 d; 95% confidence interval for mean difference 4.1-7.7). The proportion of women receiving recommended imaging within 11 months and biopsy within 3 months varied across facilities (interquartile range, 85.5%-96.5% for imaging and 79.4%-87.3% for biopsy). CONCLUSIONS: Among Medicare recipients, follow-up rates were slightly lower at facilities serving vulnerable populations, and among those women who returned for diagnostic evaluation, time to follow-up was slightly longer at facilities that served vulnerable population. Interventions should target variability in follow-up rates across facilities, and evaluate effectiveness particularly at facilities serving vulnerable populations.

Effect of pay-for-performance incentives on quality of care in small practices with electronic health records: a randomized trial.

IMPORTANCE: Most evaluations of pay-for-performance (P4P) incentives have focused on large-group practices. Thus, the effect of P4P in small practices, where many US residents receive care, is largely unknown. Furthermore, whether electronic health records (EHRs) with chronic disease management capabilities support small-practice response to P4P has not been studied. OBJECTIVE: To assess the effect of P4P incentives on quality in EHR-enabled small practices in the context of an established quality improvement initiative. DESIGN, SETTING, AND PARTICIPANTS: A cluster-randomized trial of small (<10 clinicians) primary care clinics in New York City from April 2009 through March 2010. A city program provided all participating clinics with the same EHR software with decision support and patient registry functionalities and quality improvement specialists offering technical assistance. INTERVENTIONS: Incentivized clinics were paid for each patient whose care met the performance criteria, but they received higher payments for patients with comorbidities, who had Medicaid insurance, or who were uninsured (maximum payments: $200/patient; $100,000/clinic). Quality reports were given quarterly to both the intervention and control groups. MAIN OUTCOMES AND MEASURES: Comparison of differences in performance improvement, from the beginning to the end of the study, between control and intervention clinics for aspirin or antithrombotic prescription, blood pressure control, cholesterol control, and smoking cessation interventions. Mixed-effects logistic regression was used to account for clustering of patients within clinics, with a treatment by time interaction term assessing the statistical significance of the effect of the intervention. RESULTS: Participating clinics (n = 42 for each group) had similar baseline characteristics, with a mean of 4592 (median, 2500) patients at the intervention group clinics and 3042 (median, 2000) at the control group clinics. Intervention clinics had greater adjusted absolute improvement in rates of appropriate antithrombotic prescription (12.0% vs 6.1%, difference: 6.0% [95% CI, 2.2% to 9.7%], P = .001 for interaction term), blood pressure control (no comorbidities: 9.7% vs 4.3%, difference: 5.5% [95% CI, 1.6% to 9.3%], P = .01 for interaction term; with diabetes mellitus: 9.0% vs 1.2%, difference: 7.8% [95% CI, 3.2% to 12.4%], P = .007 for interaction term; with diabetes mellitus or ischemic vascular disease: 9.5% vs 1.7%, difference: 7.8% [95% CI, 3.0% to 12.6%], P = .01 for interaction term), and in smoking cessation interventions (12.4% vs 7.7%, difference: 4.7% [95% CI, -0.3% to 9.6%], P = .02 for interaction term). Intervention clinics performed better on all measures for Medicaid and uninsured patients except cholesterol control, but no differences were statistically significant. CONCLUSIONS AND RELEVANCE: Among small EHR-enabled clinics, a P4P incentive program compared with usual care resulted in modest improvements in cardiovascular care processes and outcomes. Because most proposed P4P programs are intended to remain in place more than a year, further research is needed to determine whether this effect increases or decreases over time.

Incidence, predictors, and outcomes associated with postoperative atrial fibrillation after major noncardiac surgery.

BACKGROUND: Although major noncardiac surgery is common, few large-scale studies have examined the incidence and consequences of post-operative atrial fibrillation (POAF) in this population. We sought to define the incidence of POAF and its impact on outcomes after major noncardiac surgery. METHODS: Using administrative data, we retrospectively reviewed the hospital course of adults who underwent major noncardiac surgery at 375 US hospitals over a 1-year period. Clinically significant POAF was defined as atrial fibrillation occurring during hospitalization that necessitated therapy. RESULTS: Of 370,447 patients, 10,957 (3.0%) developed clinically significant POAF while hospitalized. Of patients with POAF, 7,355 (67%) appeared to have pre-existing atrial fibrillation and 3,602 (33%) had newly diagnosed atrial fibrillation. Black patients had a lower risk of POAF (adjusted odds ratio, 0.53; 95% CI, 0.48-0.59; P < .001). Patients with POAF had higher mortality (adjusted odds ratio, 1.72; 95% CI, 1.59-1.86; P < .001), markedly longer length of stay (adjusted relative difference, +24.0%; 95% CI, +21.5% to +26.5%; P < .001), and higher costs (adjusted difference, +$4,177; 95% CI, +$3,764 to +$4,590; P < .001). These findings did not differ by whether POAF was a recurrence of pre-existing atrial fibrillation, or a new diagnosis. CONCLUSION: POAF following noncardiac surgery is not uncommon and is associated with increased mortality and cost. Our study identifies risk factors for POAF, which appear to include race. Strategies are needed to not only prevent new POAF, but also improve management of patients with pre-existing atrial fibrillation.

Facility characteristics do not explain higher false-positive rates in diagnostic mammography at facilities serving vulnerable women.

BACKGROUND: Facilities serving vulnerable women have higher false-positive rates for diagnostic mammography than facilities serving nonvulnerable women. False positives lead to anxiety, unnecessary biopsies, and higher costs. OBJECTIVE: Examine whether availability of on-site breast ultrasound or biopsy services, academic medical center affiliation, or profit status explains differences in false-positive rates. DESIGN: We examined 78,733 diagnostic mammograms performed to evaluate breast problems at Breast Cancer Surveillance Consortium facilities from 1999 to 2005. We used logistic-normal mixed effects regression to determine if adjusting for facility characteristics accounts for observed differences in false-positive rates. MEASURES: Facilities were characterized as serving vulnerable women based on the proportion of mammograms performed on racial/ethnic minorities, women with lower educational attainment, limited household income, or rural residence. RESULTS: Although the availability of on-site ultrasound and biopsy services was associated with greater odds of a false positive in most models [odds ratios (OR) ranging from 1.24 to 1.88; P<0.05], adjustment for these services did not attenuate the association between vulnerability and false-positive rates. Estimated ORs for the effect of vulnerability indexes on false-positive rates unadjusted for facility services were: lower educational attainment [OR 1.33; 95% confidence intervals (CI), 1.03-1.74]; racial/ethnic minority status (OR 1.33; 95% CI, 0.98-1.80); rural residence (OR 1.56; 95% CI, 1.26-1.92); limited household income (OR 1.38; 95% CI, 1.10-1.73). After adjustment, estimates remained relatively unchanged. CONCLUSIONS: On-site diagnostic service availability may contribute to unnecessary biopsies, but does not explain the higher diagnostic mammography false-positive rates at facilities serving vulnerable women.

Lessons Learned From a New Reverse-Integration Model to Improve Primary Care Screening in Community Mental Health Settings.

The authors sought to describe a reverse-integration intervention aimed at improving preventive health screening in a community mental health clinic. The intervention, CRANIUM (cardiometabolic risk assessment and treatment through a novel integration model for underserved populations with mental illness), integrated primary care services into a large urban community mental health setting. It was implemented in 2015 and included a patient-centered team, population-based care, emphasis on screening, and evidence-based treatment. CRANIUM's strengths included provider acceptability, a patient-centered approach, sustained patient engagement, and economic feasibility. Challenges included underutilized staff, registry maintenance, and unanticipated screening barriers. The CRANIUM reverse-integration model can be feasibly implemented and was acceptable to providers.

Accuracy of diagnostic mammography at facilities serving vulnerable women.

BACKGROUND: Breast cancer missed on diagnostic mammography may contribute to delayed diagnoses, whereas false-positive results may lead to unnecessary invasive procedures. Whether accuracy of diagnostic mammography at facilities serving vulnerable women differs from other facilities is unknown. OBJECTIVE: To compare the interpretive performance of diagnostic mammography at facilities serving vulnerable women to those serving nonvulnerable women. DESIGN: We examined 168,251 diagnostic mammograms performed at Breast Cancer Surveillance Consortium facilities from 1999 to 2005. We used hierarchical logistic regression to compare sensitivity, false positive rates, and cancer detection rates. SUBJECTS: Women aged between 40 and 80 years underwent diagnostic mammography to evaluate an abnormal screening mammogram or breast problem. MEASURES: Facilities were assigned vulnerability indices according to the populations served based on the proportion of mammograms performed on women with lower educational attainment, racial/ethnic minority status, limited household income, or rural residences. RESULTS: Sensitivity of diagnostic mammography did not vary significantly across vulnerability indices adjusted for patient-level characteristics, but false-positive rates for diagnostic mammography examinations to evaluate a breast problem were higher at facilities serving vulnerable women defined as those with lower educational attainment (odds ratio [OR], 1.39; 95% confidence interval [CI]: 1.08, 1.79); racial/ethnic minorities (OR, 1.32; 95% CI: 0.98, 1.76); limited income (OR, 1.34; 95% CI: 1.08, 1.66); and rural residence (OR, 1.55; 95% CI: 1.27, 1.88). CONCLUSIONS: Diagnostic mammography to evaluate a breast problem at facilities serving vulnerable women had higher false positive rates than at facilities serving nonvulnerable women. This may reflect concerns that vulnerable populations may be less likely to follow-up after abnormal diagnostic mammography or concerns that such populations have higher cancer prevalence.

Informatics response to address the COVID-19 pandemic in a safety net healthcare system.

In service of particularly vulnerable populations, safety net healthcare systems must nimbly leverage health information technology (IT), including electronic health records (EHRs), to coordinate the medical and public health response to the novel coronavirus (COVID-19). Six months after the San Francisco Department of Public Health implemented a new EHR across its hospitals and citywide clinics, California declared a state of emergency in response to COVID-19. This paper describes how the IT and informatics teams supported San Francisco Department of Public Health's goals of expanding the safety net healthcare system capacity, meeting the needs of specific vulnerable populations, increasing equity in COVID-19 testing access, and expanding public health analytics and research capacity. Key enabling factors included critical partnerships with operational leaders, early identification of priorities, a clear governance structure, agility in the face of rapidly changing circumstances, and a commitment to vulnerable populations.

United States rural hospital quality in the Hospital Compare database-accounting for hospital characteristics.

BACKGROUND: Rural hospitals in the United States have demonstrated lower adherence to evidence based guidelines than their urban counterparts in national public reporting initiatives. We compared the quality of rural hospitals participating in a public reporting initiative to that of their urban counterparts using Hospital Compare, a new national database containing process measures. METHODS: Cross-sectional analyses of hospitals participating in Hospital Compare in 2005, evaluating percent adherence to guidelines for 10 processes of care for acute myocardial infarction (AMI), heart failure (HF), and community-acquired pneumonia (CAP) using multivariable linear regression analyses. RESULTS: Participating rural hospitals demonstrated lower adherence to evidence based guidelines in MI and HF quality measures (p<0.05) and higher adherence to prescribing antibiotics in a timely manner in CAP (p<0.05). Differences increased with bed size (F test for linear trend, p<0.05). After adjustment, the trends demonstrating lower adherence persisted in 6 AMI and HF measures and higher adherence in 1 CAP measure in spite of a disproportionate number of drop-outs among lower performing urban hospitals. CONCLUSIONS: Participating rural hospitals had lower performance than their urban counterparts. As the rural/urban quality gap varies by condition, bed size, and participation, we recommend comparing performance across a wide variety of condition-specific measures to enable targeted quality improvement.

Comparison of change in quality of care between safety-net and non-safety-net hospitals.

CONTEXT: Safety-net hospitals (ie, those that predominantly treat poor and underserved patients) often have lower quality of care than non-safety-net hospitals. While public reporting and pay for performance have the potential to improve quality of care at poorly performing hospitals, safety-net hospitals may be unable to invest in quality improvement. As such, some have expressed concern that these incentives have the potential to worsen existing disparities among hospitals. OBJECTIVE: To examine trends in disparities of quality of care between hospitals with high and low percentages of Medicaid patients. DESIGN AND SETTING: Longitudinal study of the relationship between hospital performance and percentage Medicaid coverage from 2004 to 2006, using publicly available data on hospital performance. A simulation model was used to estimate payments at hospitals with high and low percentages of Medicaid patients. MAIN OUTCOME MEASURES: Changes in hospital performance between 2004 and 2006, estimating whether disparities in hospital quality between hospitals with high and low percentages of Medicaid patients have changed. RESULTS: Of the 4464 participating hospitals, 3665 (82%) were included in the final analysis. Hospitals with high percentages of Medicaid patients had worse performance in 2004 and had significantly smaller improvement over time than those with low percentages of Medicaid patients. Hospitals with low percentages of Medicaid patients improved composite acute myocardial infarction performance by 3.8 percentage points vs 2.3 percentage points for those with high percentages, an absolute difference of 1.5 (P = .03). This resulted in a relative difference in performance gains of 39%. Larger performance gains at hospitals with low percentages of Medicaid patients were also seen for heart failure (difference of 1.4 percentage points, P = 0.04) and pneumonia (difference of 1.3 percentage points, P <.001). Over time, hospitals with high percentages of Medicaid patients had a lower probability of achieving high-performance status. In a simulation model, these hospitals were more likely to incur financial penalties due to low performance and were less likely to receive bonuses. CONCLUSIONS: Safety-net hospitals tended to have smaller gains in quality performance measures over 3 years and were less likely to be high-performing over time than non-safety-net hospitals. An incentive system based on these measures has the potential to increase disparities among hospitals.

Association of Rapid Molecular Testing With Duration of Respiratory Isolation for Patients With Possible Tuberculosis in a US Hospital.

Importance: New guidelines recommend that molecular testing replace sputum-smear microscopy to guide discontinuation of respiratory isolation in patients undergoing evaluation for active tuberculosis (TB) in health care settings. Objective: To evaluate the implementation and impact of a molecular testing strategy to guide discontinuation of isolation. Design, Setting, and Participants: Prospective cohort study with a pragmatic, before-and-after-implementation design of 621 consecutive patients hospitalized at Zuckerberg San Francisco General Hospital and Trauma Center who were undergoing sputum examination for evaluation for active pulmonary TB from January 2014 to January 2016. Interventions: Implementation of a sputum molecular testing algorithm using GeneXpert MTB/RIF (Xpert; Cepheid) to guide discontinuation of isolation. Main Outcomes and Measures: We measured the proportion of patients with molecular testing ordered and completed; the accuracy of the molecular testing algorithm in reference to mycobacterial culture; the duration of each component of the testing and isolation processes; length of stay; mean days in isolation and in hospital; and mean cost. We extracted data from hospital records and compared measures before and after implementation. Results: Clinicians ordered sputum testing for TB for 621 patients at ZSFG during the 2-year study period. Of 301 patients in the preimplementation period with at least 1 sputum microscopy and culture ordered, clinicians completed the rapid TB testing evaluation process for 233 (77%).Among 320 patients evaluated in the postimplementation period, clinicians ordered molecular testing for 234 (73%) patients and received results for 295 of 302 (98%) tests ordered. Median age was 54 years (interquartile range, 44-63 years), and 161 (26%) were women. The molecular testing algorithm accurately diagnosed all 7 patients with culture-confirmed TB and excluded TB in all 251 patients with Mycobacterium tuberculosis (MTB) culture-negative results. Compared with the preimplementation period, there were significant decreases in median times to final rapid test result (39.1 vs 22.4 hours, P < .001), discontinuation of isolation (2.9 vs 2.5 days, P = .001), and hospital discharge (6.0 vs 4.9 days, P = .003), on average saving $13 347 per isolated TB-negative patient. Conclusions and Relevance: A sputum molecular testing algorithm to guide discontinuation of respiratory isolation for patients undergoing evaluation for active TB was safe, feasible, widely and sustainably adopted, and provided substantial clinical and economic benefits. Molecular testing may facilitate more efficient, patient-centered evaluation for possible TB in US hospitals.

Public reporting and pay-for-performance: safety-net hospital executives' concerns and policy suggestions.

Safety-net hospitals (SNHs) may gain little financial benefit from the rapidly spreading adoption of public reporting and pay-for-performance, but may feel compelled to participate (and bear the costs of data collection) to meet public expectations of transparency and accountability. To better understand the concerns that SNH administrators have regarding public reporting and pay-for-performance, we interviewed 37 executives at randomly selected California SNHs. The main concerns noted by SNH executives were that human and financial resource constraints made it difficult for SNHs to accurately measure their performance. Additionally, some executives felt that market-driven public reporting and pay-for-performance may focus on clinical areas and incentive structures that may not be high-priority clinical areas for SNHs. Executives at SNHs suggested several policy responses to these concerns-such as offering training programs for SNH data collectors-that could be relatively inexpensive and might improve the cost-benefit ratio of public reporting and pay-for-performance programs.

Do opiates affect the clinical evaluation of patients with acute abdominal pain?

CONTEXT: Clinicians have traditionally withheld opiate analgesia from patients with acute abdominal pain until after evaluation by a surgeon, out of concern that analgesia may alter the physical findings and interfere with diagnosis. OBJECTIVE: To determine the impact of opiate analgesics on the rational clinical examination and operative decision for patients with acute abdominal pain. DATA SOURCES AND STUDY SELECTION: MEDLINE (through May 2006), EMBASE, and hand searches of article bibliographies to identify placebo-controlled randomized trials of opiate analgesia reporting changes in the history, physical examination findings, or diagnostic errors (those resulting in "management errors," defined as the performance of unnecessary surgery or failure to perform necessary surgery in a timely fashion). DATA EXTRACTION: Two authors independently reviewed each study, abstracted data, and classified study quality. A third reviewer independently resolved discrepancies. DATA SYNTHESIS: Studies both in adults (9 trials) and in children (3 trials) showed trends toward increased risks of altered findings on the abdominal examination due to opiate administration, with risk ratios for changes in the examination of 1.51 (95% confidence interval [CI], 0.85 to 2.69) and 2.11 (95% CI, 0.60 to 7.35), respectively. When the analysis was restricted to the 8 adult and pediatric trials that reported significantly greater analgesia for patients who received opiates compared with those who received placebo, the risk of physical examination changes became significant (risk ratio, 2.13; 95% CI, 1.14 to 3.98). These trials exhibited significant heterogeneity (I2 = 68.6%; P = .002), and only 2 trials distinguished clinically significant changes such as loss of peritoneal signs from all other changes; consequently, we analyzed risk of management errors as a marker for important changes in the physical examination. Opiate administration had no significant association with management errors (+0.3% absolute increase; 95% CI, -4.1% to +4.7%). The 3 pediatric trials showed a nonsignificant absolute decrease in management errors (-0.8%; 95% CI, -8.6% to +6.9%). Across adult and pediatric trials with adequate analgesia, opiate administration was associated with a nonsignificant absolute decrease in the risk of management errors (-0.2%; 95% CI, -4.0% to +3.6%). CONCLUSIONS: Opiate administration may alter the physical examination findings, but these changes result in no significant increase in management errors. The existing literature does not rule out a small increase in errors, but this error rate reflects a conservative definition in which surgeries labeled as either delayed or unnecessary may have met appropriate standards of care. In published research reports, no patient experienced major morbidity or mortality attributable to opiate administration.

Displaying radiation exposure and cost information at order entry for outpatient diagnostic imaging: a strategy to inform clinician ordering.

BACKGROUND: Displaying radiation exposure and cost information at electronic order entry may encourage clinicians to consider the value of diagnostic imaging. METHODS: An urban safety-net health system displayed radiation exposure information for CT and cost information for CT, MRI and ultrasound on an electronic referral system for outpatient ordering. We assessed whether there were differences in numbers of outpatient CT scans and MRIs per month relative to ultrasounds before and after the intervention, and evaluated primary care clinicians' responses to the intervention. RESULTS: There were 23 171 outpatient CTs, 15 052 MRIs and 43 266 ultrasounds from 2011 to 2014. The ratio of CTs to ultrasounds decreased by 15% (95% CI 9% to 21%), from 58.2 to 49.6 CTs per 100 ultrasounds; the ratio of MRIs to ultrasounds declined by 13% (95% CI 7% to 19%), from 37.5 to 32.5 per 100. Of 300 invited, 190 (63%) completed the web-based survey in 17 clinics. 154 (81%) noticed the radiation exposure information and 158 (83.2%) noticed the cost information. Clinicians believed radiation exposure information was more influential than cost information: when unsure clinically about ordering a test (radiation=69.7%; cost=46.4%), when a patient wanted a test not clinically indicated (radiation=77.5%; cost=54.8%), when they had a choice between imaging modalities (radiation=77.9%; cost=66.6%), in patient care discussions (radiation=71.9%; cost=43.2%) and in trainee discussions (radiation=56.5%; cost=53.7%). Resident physicians and nurse practitioners were more likely to report that the cost information influenced them (p<0.05). CONCLUSIONS: Displaying radiation exposure and cost information at order entry may improve clinician awareness about diagnostic imaging safety risks and costs. More clinicians reported the radiation information influenced their clinical practice.

From the closest observers of patient care: a thematic analysis of online narrative reviews of hospitals.

OBJECTIVE: Patient-centred care has become a priority in many countries. It is unknown whether current tools capture aspects of care patients and their surrogates consider important. We investigated whether online narrative reviews from patients and surrogates reflect domains in the Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS) and we described additional potential domains. DESIGN: We used thematic analysis to assess online narrative reviews for reference to HCAHPS domains and salient non-HCAHPS domains and compared results by reviewer type (patient vs surrogate). SETTING: We identified hospitals for review from the American Hospital Association database using a stratified random sampling approach. This approach ensured inclusion of reviews of a diverse set of hospitals. We searched online in February 2013 for narrative reviews from any source for each hospital. PARTICIPANTS: We included up to two narrative reviews for each hospital. EXCLUSIONS: Outpatient or emergency department reviews, reviews from self-identified hospital employees, or reviews of <10 words. RESULTS: 50.0% (n=122) of reviews (N=244) were from patients and 38.1% (n=93) from friends or family members. Only 57.0% (n=139) of reviews mentioned any HCAHPS domain. Additional salient domains were: Financing, including unexpected out-of-pocket costs and difficult interactions with billing departments; system-centred care; and perceptions of safety. These domains were mentioned in 51.2% (n=125) of reviews. Friends and family members commented on perceptions of safety more frequently than patients. CONCLUSIONS: A substantial proportion of consumer reviews do not mention HCAHPS domains. Surrogates appear to observe care differently than patients, particularly around safety.
