Patient and system factors associated with unassisted and injurious falls in hospitals: an observational study.
Unassisted falls are more likely to result in injury than assisted falls. However, little is known about risk factors for falling unassisted. Furthermore, rural hospitals, which care for a high proportion of older adults, are underrepresented in research on hospital falls. This study identified risk factors for unassisted and injurious falls in rural hospitals.

Long peripheral catheters: a retrospective review of major complications.
The risk of infectious and noninfectious complications associated with long peripheral catheters (LPCs) is unknown. In this retrospective study of 539 catheters, the investigators did a retrospective review of major complications. Among other discoveries, they found LPCs were often placed for the indications of difficult access and long-term antibiotics.

Evidence-based development of a nephrotoxic medication list to screen for acute kidney injury risk in hospitalized children.
This paper describes an initiative to develop an evidence-based list of nephrotoxic medications to screen for acute kidney injury (AKI) risk in hospitalized children. This initiative, called the Nephrotoxic Injury Negated by Just-in-time Action quality improvement collaborative, convened a Nephrotoxic Medication (NTMx) Subcommittee composed of pediatric nephrologists, a pharmacist, and a pediatric intensivist. The committee reviewed NTMx lists, conducted a literature review of the disputed medications, and assigned an evidence grade based on the association between nephrotoxicity and the quality of the data. The subcommittee then came to a majority consensus to which medications should be included on the list. The list was presented to the larger collaborative and voted on. This list will be continually updated and voted on annually.

Association of open approach vs laparoscopic approach with risk of surgical site infection after colon surgery.
The authors assessed whether laparoscopic colon surgery is associated with a lower surgical site infection rate than open-approach laparoscopy. They found that policy changes that promote surgical education and resources for laparoscopy, especially at low-adoption hospitals, may be associated with reduced colon surgical site infection rates. They recommend support of the development of innovative educational policies to help achieve improvement in patient outcomes and decreased health care use in colon surgery.

Evaluating the use of multiteam systems to manage the complexity of inpatient falls in rural hospitals.
Researchers evaluated the implementation and outcomes of evidence-based fall-risk-reduction processes when those processes are implemented using a multiteam system (MTS) structure. They found that multiteam systems that effectively coordinate fall-risk-reduction processes may improve the capacity of hospitals to manage the complex patient, environmental, and system factors that result in falls.

Refining the predictive variables in the "Surgical Risk Preoperative Assessment System" (SURPAS): a descriptive analysis.
The authors systematically evaluated eight issues to improve the Surgical Risk Preoperative Assessment System (SURPAS). They found that refinements to SURPAS were successful in improving accuracy. They developed graphical displays of risk for providers and patients, including a take-home handout and automated documentation of risk in the electronic health record in order to facilitate easier implementation of SURPAS.

Development and validation of a pragmatic natural language processing approach to identifying falls in older adults in the emergency department.
This study examined development and validation of a pragmatic natural language processing (NLP) approach to identify fall risk in older adults after emergency department (ED) visits. A single center retrospective review using data from 500 emergency department provider notes on older adults age 65 and older were random selected for analysis. The NLP algorithm successfully identified falls in ED notes with over 90% precision, and looks promising to reduce labor-intensive manual abstraction.

Mining social media data to assess the risk of skin and soft tissue infections from allergen immunotherapy.
This study examined large social media databases including Facebook, Twitter, and Reddit to identify postings of rare incidents of contamination or infection from extracts for allergen immunotherapy (AIT). They used natural language processing (NLP) related to AIT from 2012 to 2016. They compared posts on adverse events for AIT compared to influenza vaccinations. The results showed that both types of posts are rare events.

Critical review, development, and testing of a taxonomy for adverse events and near misses in the emergency department.
Researchers created and tested a taxonomy for adverse events (AEs) and near misses for use in the emergency department (ED). This taxonomy is patient-centered, as opposed to most taxonomies which fail to describe harm experienced by patients and focus instead on errors and uses too broad categorizations. The authors reviewed candidate taxonomies using an iterative process and selected the Adventist Health Systems AE taxonomy and modified it for use in the ED. After testing with reviewers, agreement with the criterion standard was 92% at the category level and 88% at the subcategory level. Performance from individual raters ranged from very good (88%) to near perfect (98%) at the main category level.

Preoperative risk evaluation for pancreatic fistula after pancreaticoduodenectomy.
The purpose of this study was to identify risk factors for clinically relevant postoperative pancreatic fistula that are routinely available in the preoperative setting. Results showed that outcomes were best for patients with three or fewer identified risk factors. The researchers conclude that risk evaluation could be a useful tool in patient counseling and surgical planning.

Risk factors for post-pancreaticoduodenectomy delayed gastric emptying in the absence of pancreatic fistula or intra-abdominal infection.
Researchers sought to define the incidence of delayed gastric emptying (DGE) and identify risk factors for DGE in patients without pancreatic fistula or other intra-abdominal infections. They found that patients were more likely to develop DGE if they were over 74 years of age, male, had undergone pylorus-sparing pancreaticoduodenectomy (PD), or had a prolonged operative time. They conclude that the incidence of DGE after PD is notable even in patients without other abdominal complications and suggested that identification of patients at increased risk for DGE may aid patient counseling as well as decisions regarding surgical technique, enteral feeding access, and enhanced-recovery pathways.

Comparison of measures to predict mortality and length of stay in hospitalized patients.
This study compared performance of five measures in order to predict mortality and length of stay (LOS) in hospitalized adults using claims data; the measures included three comorbidity composite scores, 3 M risk of mortality, and 3 M severity of illness subclasses. Binary logistic and zero-truncated negative binomial regression models were applied to a 2-year retrospective dataset of adult inpatient admissions from a large hospital system in New York City. All five measures demonstrated a good to strong model fit for predicting in-hospital mortality. The authors conclude that these measures can guide nurse managers in assigning nursing care and coordinating patient services, as well as administrators in supporting optimal nursing care more effectively and efficiently.

Less lumens-less risk: a pilot intervention to increase the use of single-lumen peripherally inserted central catheters.
To reduce risk of complications, existing guidelines recommend use of peripherally inserted central catheters (PICCs) with the minimal number of lumens. This recommendation, however, is difficult to implement in practice. The investigators conducted a pilot study to increase the use of single-lumen PICCs in hospitalized patients. The authors indicated that implementing a single-lumen PICC default and providing education and indications for multilumen devices improved PICC appropriateness.

Central nervous system medication burden and risk of recurrent serious falls and hip fractures in Veterans Affairs nursing home residents.
This study investigated the association between taking central nervous system (CNS) medications with the risk of serious falls and hip fractures. Study participants were residents at a Veterans Health Administration (VHA) Community Living Center (CLC) between July 1, 2005 and June 30, 2009. This was a nested case-control study. The investigators concluded that there was a higher risk in those residents receiving 3.0 or more daily CNS medications.

Hemodynamic impact of oxygen desaturation during tracheal intubation among critically ill children with cyanotic and noncyanotic heart disease.
The objective of this study was to determine a level of oxygen desaturation associated with increased risk of tracheal intubation events in children in a pediatric or cardiac ICU with cyanotic and noncyanotic heart disease. Oxygen desaturation was measured by a fall in pulse oximetry from baseline after pre-oxygenation. The primary outcome was occurrence of hemodynamic tracheal intubation associated events defined as cardiac arrest, hypotension, or dysrhythmia. Results indicate that oxygen desaturation by 30% or more is associated with increased odds for adverse hemodynamic events, after adjusting for confounders. Oxygen desaturation was observed more often in children with cyanotic than those with noncyanotic heart disease, but hemodynamic tracheal intubation associated event rates were similar.

An evaluation of differences in risk factors for individual types of surgical site infections after colon surgery.
The authors developed four independent, multivariate, predictive models to assess the unique associations between risk factors and each surgical site infection (SSI) group: superficial, deep, organ space, and an aggregate of all 3 types of SSIs. They found that unique risks for superficial SSIs include diabetes, chronic obstructive pulmonary disease, and dyspnea; deep SSIs had the greatest magnitude of association with BMI and the greatest incidence of wound disruption; and organ space SSIs were often owing to anastomotic leaks and were uniquely associated with disseminated cancer, preoperative dialysis, preoperative radiation treatment, and a bleeding disorder. They concluded that more effective prevention strategies may be developed by reporting and examining each type of SSI separately.

A socio-technical, probabilistic risk assessment model for surgical site infections in ambulatory surgery centers.
The researchers sought to identify the risk factors associated with surgical site infections (SSIs) resulting from procedures performed at ambulatory surgery centers (ASCs) and to design an intervention to mitigate the likelihood of SSIs for the most common risk factors that were identified by the socio-technical probabilistic risk assessment (ST-PRA) tool for a particular surgical procedure. They found that failure to protect the patient effectively accounted for 51.9% of SSIs in the ambulatory care setting. Critical components of this event included skin preparation, antibiotic administration, staff training, proper response to glove punctures during surgery, and adherence to surgical preparation rules related to the wearing of jewelry, watches, and artificial nails. They determined that, assuming a 75% reduction in noncompliance on any combination of 2 of these 5 components, the risk for an SSI decreased.

Risk prediction model for heart failure and cardiomyopathy after adjuvant trastuzumab therapy for breast cancer.
The investigators sought to develop a clinical risk score that identifies older women with breast cancer who are at higher risk of heart failure or cardiomyopathy after trastuzumab. That found that a 7-factor risk score was able to stratify 3-year risk of heart failure/cardiomyopathy after trastuzumab between the lowest and highest risk groups by more than 2-fold in a Medicare population.
