Deliberate learning in health care: the effect of importing best practices and creative problem solving on hospital performance improvement.
The authors examined the effect on quality improvement of two common but distinct approaches to organizational learning, importing best practices and creative problem solving, in hospitals focused on improving treatment time for patients with heart attacks. They found that importing best practices helps hospitals achieve initial phase improvement, after which significant further improvement requires creative problem solving as well.

Medicare claims can be used to identify US hospitals with higher rates of surgical site infection following vascular surgery.
This study found that among Medicare patients who underwent vascular surgery at 2,512 U.S. hospitals, a patient undergoing surgery in a hospital ranked in the worst-performing decile based on claims had a 2.5 times greater likelihood of developing a chart-confirmed surgical site infection relative to a patient characteristics in a hospital in the best-performing decile.

Do hospitals cross-subsidize?
The authors used repeated shocks to a profitable service in the market for hospital-based medical care to test for cross-subsidization of unprofitable services. They studied how incumbent hospitals adjusted their provision of three uncontested services that are widely considered to be unprofitable. They estimated that the hospitals most exposed to entry reduced their provision of psychiatric, substance-abuse, and trauma care services at a rate of about one uncontested-service admission for every four cardiac admissions they stood to lose.

Hospital practices in the collection of patient race, ethnicity, and language data: a statewide survey, California, 2011.
The authors reported on a sruvey of general acute care hospitals in California to elucidate practices regarding collection and auditing of patient race, ethnicity, and primary spoken language (REL). They found that the majority of hospitals used standardized forms for collection, and 75% audited patient information for completeness. They concluded that California hospitals are collecting information on patient REL as mandated, but variation in data collection exists, and hospitals may benefit from standardized data collection and auditing practices.

Hospital financial performance in the recent recession and implications for institutions that remain financially weak.
This study of 2,971 private short-term general medical or surgical hospitals found that hospitals that were financially weak before the recession remained so during and after the recession. The total margins of nonprofit hospitals declined in 2008 but returned to pre-recession levels by 2011. The recession did not create additional fiscal pressure on hospitals that were previously financially weak or in safety-net roles.

Ranking trauma center quality: can past performance predict future performance?
This study investigated whether hospital quality metrics based on prior years of data reliably predict future performance. It found that although the future performance of individual trauma centers can be predicted using 2-year-old data, the performance of individual trauma centers cannot be reliably predicted using performance reports based on data that is 3, 4, or 5 years old.

The association of hospital quality ratings with adverse events.
The researchers used a survey of 2,582 patients hospitalized at 16 acute care Massachusetts hospitals to understand how patient-reported quality is related to adverse events (AEs). Although patients with AEs rated hospital quality lower than others, patients with AEs who experienced ‘service recovery’ rated their quality of care at levels similar to those not experiencing AEs.

Redesigning hospital alarms for patient safety: alarmed and potentially dangerous.
In this paper, the authors discuss redesigning hospital alarms for patient safety. They note the benefits and dangers of patient safety alarms and outline potential solutions to make patient safety alarms more effective. The investigators suggest that the scope and design of alarm systems must shift from the status quo to a biologically valid, clinically relevant, patient-centered model. They assert that existing technology allows integration and intelligent assessment of patient data to create advanced alarm systems.

Composite measures for profiling hospitals on bariatric surgery performance.
The study objective was to develop a novel composite measure for profiling hospital performance with bariatric surgery. Composite measures are much better at explaining hospital-level variation in serious complications and predicting future performance than other approaches. This study provides preliminary data that empirically weighted composite outcomes measures may be better than existing alternatives for selective referral and outcomes feedback programs.

Critical access hospitals and cost shifting.
In the context of ongoing discussion about critical access hospital (CAH) reimbursement, it is important to better understand how health care providers currently utilize funds from the CAH Programs. This study found that among hospitals converted to CAH designation while part of a hospital system, the relative proportion of costs that reflect shared services provided by the parent organization is significantly higher than would be expected in the post-conversion period.

Factors associated with adoption of robotic surgical technology in US hospitals and relationship to radical prostatectomy procedure volume.
The authors aimed to identify the factors associated with hospitals' decisions to adopt robotic technology and the consequences of these decisions. They found that hospitals in areas where a higher proportion of other hospitals had already acquired a robot were more likely to acquire one, as were those with more than 300 beds and teaching hospitals. They also found a significant association between years with a robot and the change in the number of radical prostatectomies. They concluded that local area robot competition was associated with the rapid spread of robot technology in the United States.

Universal glove and gown use and acquisition of antibiotic-resistant bacteria in the ICU: a randomized trial.
Antibiotic-resistant bacteria are associated with increased patient morbidity and mortality. It is unknown whether wearing gloves and gowns for all patient contact in the intensive care unit (ICU) decreases acquisition of antibiotic-resistant bacteria. The purpose of this study was to assess whether wearing gloves and gowns for all patient contact in the ICU decreases acquisition of methicillin-resistant Staphylococcus aureus (MRSA) or vancomycin-resistant Enterococcus (VRE) compared with usual care.

Health information technology and hospital patient safety: a conceptual model to guide research.
The authors developed a conceptual model to guide research in sorting out the complex relationships between health information technology (HIT) and the quality and safety of care. They found the model difficult to operationalize because available HIT adoption data did not characterize features and extent of usage, and patient safety measures did not elucidate the process failures leading to safety-related outcomes. Their findings illustrated the critical need for collecting data that are germane to HIT and the possible mechanisms by which HIT may affect inpatient safety.

Black patients more likely than whites to undergo surgery at low-quality hospitals in segregated regions.
The authors assessed the extent to which living in racially segregated areas and living in geographic proximity to low-quality hospitals contribute to the disparity of black patients undergoing surgery at lower-quality hospitals more frequently than whites. Using Medicare data, they found that black patients tended to live closer to higher-quality hospitals than white patients but were more likely to receive surgery at low-quality hospitals. To address these disparities, care navigators and public reporting of comparative quality could steer patients and their referring physicians to higher-quality hospitals, while quality improvement efforts could focus on improving outcomes for high-risk surgery at hospitals that disproportionately serve black patients.

Medicare and commercial inpatient resource use: impact of hospital competition.
The authors examined the influence of hospital competition on small-area inpatient resource use by payer. Using HCUP data, they found that policies or incentives that promote or encourage competition in less competitive markets may reduce variation in resource use for both Medicare and private payers.
