Comparison of cost and complication rates for profiling hospital performance in lumbar fusion for spondylolisthesis.
Investigators sought to evaluate the reliability of 90-day inpatient hospital costs, overall complications, and rates of serious complications for profiling hospital performance in lumbar fusion surgery for spondylolisthesis. Using HCUP data, they found that 90-day inpatient costs were highly reliable for assessing variation across hospitals, whereas overall and serious complications were only moderately reliable for profiling performance. They concluded that their results support the viability of emerging bundled payment programs that assume true differences in costs of care exist across hospitals.

Inside the black box of improving on nursing home quality measures.
This qualitative study investigated how nursing homes (NHs) interact with quality measures (QMs) used by Nursing Home Compare (NHC) as part of its 5-star rating system. Semistructured interviews were conducted with 110 NH personnel and 23 NH provider association representatives. Observations of organizational processes in 12 NHs in three states were also done. The authors found that most NHs are working to improve the quality of care they provide, not merely to improve their QM scores. They also found limitations with the QMs, suggesting that the QMs on their own may not accurately reflect the quality of care that NHs provide. The findings suggest several changes to improve NHC.

Comparing web and mail protocols for administering Hospital Consumer Assessment of Healthcare Providers and Systems surveys.
This study’s objective was to compare results of using web-based and mail HCAHPS data collection protocols. The cohort included patients who were hospitalized in a New England Hospital. Patients who provided email addresses were randomized to 1 of 3 data collection protocols: web-only, web with postal mail follow-up, and postal mail only. Those who did not provide email addresses were surveyed by postal mail only. The study lasted 8 weeks. Measures looked at included response rates, characteristics of respondents, 6 composite measures of their patient experiences, and two ratings of the hospital. Web-only response rates were significantly lower than for mail or combined protocols, and those who had not provided email addresses also had lower response rates. Older adults over age 65 were more likely to respond to all protocols, especially for mail-only respondents. Respondents without email addresses were older, less educated, and reported worse health than those who had email addresses.

Usefulness of child HCAHPS survey data for improving inpatient pediatric care experiences.
Quality improvement (QI) requires data, indicators, and national benchmarks. Knowledge about the usefulness of Child Hospital Consumer Assessment of Healthcare Providers and Systems (Child HCAHPS) data are lacking. In this study the investigators examined quality leader and frontline staff perceptions about patient experience measurement and use of Child HCAHPS data for QI. The investigators surveyed children's hospital leaders and staff about their use of Child HCAHPS for QI, including measures from other studies. They compared scale and item means for leaders and staff and compared means to other studies.

Assessing hospital electronic health record vendor performance across publicly reported quality measures.
The authors measured hospital performance, stratified by electronic health record (EHR) vendor, across 4 quality metrics. They found that no EHR vendor was associated with higher quality across all measures, and the 2 largest vendors were not associated with the highest scores. Only a small fraction of quality variation was explained by EHR vendor choice. They concluded that top performance on quality measures can be achieved with any EHR vendor, as much of quality performance is driven by the hospital and how it uses the EHR.

Quality of care for youth hospitalized for suicidal ideation and self-harm.
The authors examined performance on quality measures for pediatric inpatient suicidal ideation/self-harm care, and whether performance is associated with reutilization. Subjects were patients aged 5 to 17 years hospitalized for suicidal ideation/self-harm. Their findings revealed disparities and deficits in the quality of care received by youth with suicidal ideation/self-harm. They recommended providing caregivers lethal means restriction counseling prior to discharge in order to help prevent readmission.

Treatment patterns and clinical outcomes after the introduction of the Medicare Sepsis Performance Measure (SEP-1).
This study evaluated the effect of Severe Sepsis and Septic Shock Early Management Bundle (SEP-1) on treatment patterns and patient outcomes. Findings showed that, two years after its implementation, SEP-1 was associated with variable changes in process measures, with the greatest effect being an increase in lactate measurement within 3 hours of sepsis onset. There were small increases in antibiotic administration and fluid administration, a small increase in ICU admissions, and no changes in mortality or discharge to home.

Association of Medicare Advantage Star Ratings with racial, ethnic, and socioeconomic disparities in quality of care.
This cross-sectional study looked at racial/ethnic minority and socioeconomic disparities in ratings for Medicare Advantage (MA) plans, which disproportionately enroll these populations. A total of 1,578,564 enrollees were included in this analysis that used 22 measures of quality and satisfaction at the individual enrollee level, aggregated into simulated star ratings from 2-5 stratified by socioeconomic status (SES) and race/ethnicity. Low SES enrollees had simulated stratified star ratings 0.5 stars lower than individuals with high SES in the same contract. Black enrollees had simulated star ratings that were 0.3 stars lower and Hispanic enrollees had 0.1 lower simulated star ratings than White enrollees in the same contract. There was a larger difference in ratings with 4.5 to 5-star contracts with Black and Hispanic enrollees with Whites, and no statistical difference in 2.0 to 2.5 star-rated contracts. There was only low correlation between simulated ratings for enrollees of low SES and high SES.

Improvement in patient safety may precede policy changes: trends in patient safety indicators in the United States, 2000-2013.
This study’s aim was to assess changes in national patient safety trends that corresponded to U.S. pay-for-performance reforms. The study analyzed 13 patient safety indicators (PSIs) that were developed by AHRQ. PSI trends, Center for Medicaid and Medicare Services payment policy changes, and Inpatient Prospective Payment System regulations and notices between 2000 and 2013 were analyzed. Twelve of the thirteen PSIs had decreasing or stable trends in the last 5 years of the study. Central-line bloodstream infections had the greatest annual decrease (-31.1 annual percent change between 2006 and 2013) whereas postoperative respiratory failure had the smallest annual percent change (-3.5 between 2005 and 2013). Significant decreases in trends preceded federal payment reform initiatives in all but postoperative hip fracture. These findings suggest that intense public discourses targeting patient safety may drive national policy reforms.

Clinical quality measure exchange is not easy.
The Trial of Aggregate Data Exchange for Maintenance of Certification and Raising Quality was a randomized controlled trial which first had to test whether quality reporting could be a by-product of clinical care. The investigators reported on the initial descriptive study of the capacity for and quality of exchange of whole-panel, standardized quality measures from health systems. They concluded that the secure transfer of standardized, physician-level quality measures from 4 health systems with mature measure processes proved difficult. There were many errors that required human intervention and manual repair, precluding full automation.

Exploring the association between the quality of HIV care in nursing homes and hospitalization.
Persons living with HIV/AIDS (PLWH) are living long enough to need age-related and HIV-related nursing home (NH) care. Nursing home quality of care has been associated with risk for hospitalization, but it is unknown if quality of HIV care in NHs affects hospitalization in this population. In this study, the investigators assessed HIV care quality with four national measures adapted for the NH setting.

Older veterans undergoing inpatient surgery: what is the compliance with best practice guidelines?
This study’s objective was to determine the documented compliance with best practice guidelines for optimal perioperative care for the older adult surgical patient that were created by the American College of Surgeons Quality Improvement Program and the American Geriatrics Society. The guidelines include 38 measures. A retrospective chart review was conducted on 86 older adults undergoing elective inpatient coronary artery bypass graft, prostatectomy, or colectomy over a 2-year period at a single Veterans Affairs hospital. Mean reported compliance across measures was 41% ± 4%. Of the 38 analyzed measures, 10 measures were achieved for 0 patients, and only 1 patient for 7 measures. Future work is needed to understand barriers for implementation.

Pediatric health care quality measures: considerations for pharmacotherapy.
The authors used the Pediatric Quality Measures Program that arose from the Children's Health Insurance Program Reauthorization Act in the United States to illustrate the challenges in developing quality measures of pediatric pharmacotherapy. They identified the challenges aw being twofold: (i) weak evidence base for the specific pharmacotherapy in children and (ii) limited data to calculate the measure. They concluded that health information technology is emerging as a tool to improve quality measurement but presents additional challenges.

Resident satisfaction surveys and clinical quality of care in nursing homes: two sides of the same coin?
The authors of this article believe that quality of nursing homes is a complex, multidimensional construct. Unlike acute care hospitals, where patients are typically treated for one specific condition and stay for a short period of time, the length of stays in nursing homes varies widely. They argue that neither the individual assessment of clinical quality nor evaluation of hotel services are sufficient.

Impact of voluntary accreditation on short-stay rehabilitative measures in U.S. nursing homes.
The purpose of this paper was to examine accreditation from nursing homes accredited by the Commission on Accreditation of Rehabilitation Facilities (CARF) and whether this is associated with improved rehabilitation care. Findings indicated that CARF-accredited nursing homes demonstrate better quality with regard to the short-stay quality measures and that approaches beyond traditional regulation and governmental inspections are necessary to improve the quality of care in nursing homes.

Quality improvement under nursing home compare: the association between changes in process and outcome measures.
The researchers tested the extent to which improvements in outcomes of care are explained by changes in nursing home processes. Of the 5 outcome measures examined, they found that only improvements in the percentage of nursing home residents in moderate or severe pain were associated with changes in nursing home processes of care. They concluded that understanding the mechanism behind improvements in nursing home outcomes may be key to successfully achieving broad quality improvements across nursing homes.
