A user needs assessment to inform health information exchange design and implementation.

BACKGROUND: Important barriers for widespread use of health information exchange (HIE) are usability and interface issues. However, most HIEs are implemented without performing a needs assessment with the end users, healthcare providers. We performed a user needs assessment for the process of obtaining clinical information from other health care organizations about a hospitalized patient and identified the types of information most valued for medical decision-making. METHODS: Quantitative and qualitative analysis were used to evaluate the process to obtain and use outside clinical information (OI) using semi-structured interviews (16 internists), direct observation (750 h), and operational data from the electronic medical records (30,461 hospitalizations) of an internal medicine department in a public, teaching hospital in Tampa, Florida. RESULTS: 13.7 % of hospitalizations generate at least one request for OI. On average, the process comprised 13 steps, 6 decisions points, and 4 different participants. Physicians estimate that the average time to receive OI is 18 h. Physicians perceived that OI received is not useful 33-66 % of the time because information received is irrelevant or not timely. Technical barriers to OI use included poor accessibility and ineffective information visualization. Common problems with the process were receiving extraneous notes and the need to re-request the information. Drivers for OI use were to trend lab or imaging abnormalities, understand medical history of critically ill or hospital-to-hospital transferred patients, and assess previous echocardiograms and bacterial cultures. About 85 % of the physicians believe HIE would have a positive effect on improving healthcare delivery. CONCLUSIONS: Although hospitalists are challenged by a complex process to obtain OI, they recognize the value of specific information for enhancing medical decision-making. HIE systems are likely to have increased utilization and effectiveness if specific patient-level clinical information is delivered at the right time to the right users.

Human error and patient safety: interdisciplinary course.

BACKGROUND: The medical community has only recently begun to address how human error affects patient safety. In order to confront human error in medicine, there is a need to teach students who are entering the health professions how potential errors may manifest and train them to prevent or mitigate these problems. PURPOSE: The objective is to describe a semester-long, interdisciplinary, human error and patient safety course taught at the University of South Florida. METHODS: Six interdisciplinary groups, composed of students from five of the university's colleges, were formed. The curriculum consisted of expert lecturers, readings, case studies, and analysis of patient safety problems. Students were evaluated based on their group's work on the final project and peer evaluations. RESULTS: Nursing students scored the highest in each category evaluated. Physicians and medical students had the lowest evaluations in team participation and active engagement. All students rated the course highly and indicated that it enhanced their ability to work in interprofessional settings. CONCLUSIONS: The students showed improved knowledge and substantive skill level relative to patient safety and human error concepts. Working in interdisciplinary teams gave the students a better understanding of the role each discipline can have in improving health care systems and health care delivery.

Difference in Composite End Point of Readmission and Death Between Malnourished and Nonmalnourished Veterans Assessed Using Academy of Nutrition and Dietetics/American Society for Parenteral and Enteral Nutrition Clinical Characteristics.

BACKGROUND: Previous studies have demonstrated an association between malnutrition and poor outcomes. The primary objective of this study was to explore the difference in the composite end point of readmission rate or mortality rate between hospitalized veterans with and without malnutrition. MATERIALS AND METHODS: This was a retrospective chart review comparing veterans with malnutrition based on a modified version of the Academy of Nutrition and Dietetics/American Society for Parenteral and Enteral Nutrition consensus characteristics that used 5 of the 6 clinical characteristics to a matched control group of nonmalnourished veterans based on age, admitting service, and date of admission who were admitted between August 1, 2012, and December 1, 2014. Data were extracted from the medical record. Multivariate analysis was used to identify predictors of outcomes. RESULTS: In total, 404 patients were included in the final analysis. All end points were found to be statistically significant. The malnourished group was more likely to meet the composite end point (odds ratio [OR], 5.3), more likely to be readmitted within 30 days (OR, 3.4), more likely to die within 90 days of discharge (OR, 5.5), and more likely to have a length of stay >7 days (OR, 4.3) compared with the nonmalnourished group. Length of stay was significantly longer in the malnourished group, 9.80 (11.5) vs 4.38 (4.5) days. CONCLUSION: Malnutrition was an independent risk factor for readmission within 30 days or death within 90 days of discharge. Malnourished patients had higher rates of readmission, higher mortality rates, and longer lengths of stay and were more likely to be discharged to nursing homes.

Preventable Readmission Risk Factors for Patients With Chronic Conditions.

Evidence indicates that the largest volume of hospital readmissions occurs among patients with preexisting chronic conditions. Identifying these patients can improve the way hospital care is delivered and prioritize the allocation of interventions. In this retrospective study, we identify factors associated with readmission within 30 days based on claims and administrative data of nine hospitals from 2005 to 2012. We present a data inclusion and exclusion criteria to identify potentially preventable readmissions. Multivariate logistic regression models and a Cox proportional hazards extension are used to estimate the readmission risk for 4 chronic conditions (congestive heart failure [CHF], chronic obstructive pulmonary disease [COPD], acute myocardial infarction, and type 2 diabetes) and pneumonia, known to be related to high readmission rates. Accumulated number of admissions and discharge disposition were identified to be significant factors across most disease groups. Larger odds of readmission were associated with higher severity index for CHF and COPD patients. Different chronic conditions are associated with different patient and case severity factors, suggesting that further studies in readmission should consider studying conditions separately.

Lessons learned at sea--ocean sailing as a metaphor for surgical training.

Surgical education is in the process of tumultuous change. Mastering this change will require a new set of competencies and a new understanding of the medical education process. While accreditation agencies are rapidly working to define the new criteria and benchmarks, training programs are quickly pulling together curricula, objectives, and evaluation tools. Yet much has already been learned in other complex, high-risk activities. Blue water sailing, ocean racing, and trans-Atlantic crossing are all activities that require a renewed form of leadership and an understanding of how knowledge, skill, and behavior come together to define the competent sailor. Ideas learned in such endeavors may assist the surgical educator in defining the horizons and the hazards of this uncharted voyage.

Evaluation of an error-reduction training program for surgical residents.

PURPOSE: To reduce errors in surgery using a resident training program based on a taxonomy that highlights three kinds of errors: judgment, inattention to detail, and problem understanding. METHOD: The training program module at the University of South Florida incorporated a three-item situational judgment test, video training (which included a lecture and behavior modeling), and role-plays (in which residents participated and received feedback from faculty). Two kinds of outcome data were collected from 33 residents during 2006-2007: (1) behaviors during the training and (2) on-the-job surgical complication records 12 months before and 6 months after training. For the data collected during training, participants were assigned to a condition (19 video condition, 13 control condition); for the data collected on the job, an interrupted time series design was used. RESULTS: Data from 32 residents were analyzed (one resident's data were excluded). One of the situational judgment items improved significantly over time (d = 0.45); the other two did not (d = 0.36, 0.25). Surgical complications and errors decreased over the course of the study (the correlation between complications and time in months was r = -0.47, for errors and time, r = -0.55). Effects of video behavior modeling on specific errors measured during role-plays were not significant (effect sizes for binary outcomes were phi = -0.05 and phi = 0.01, and for continuous outcomes, d ranged from -0.02 to 0.34). CONCLUSIONS: The training seemed to reduce errors in surgery, but the training had little effect on the specific kinds of errors targeted during training.

Human error, not communication and systems, underlies surgical complications.

OBJECTIVE: This study prospectively assesses the underlying errors contributing to surgical complications over a 12-month period in a complex academic department of surgery using a validated scoring template. BACKGROUND: Studies in "high reliability organizations" suggest that systems failures are responsible for errors. Reports from the aviation industry target communication failures in the cockpit. No prior studies have developed a validated classification system and have determined the types of errors responsible for surgical complications. METHODS: A classification system of medical error during operation was created, validated, and data collected on the frequency, type, and severity of medical errors in 9,830 surgical procedures. Statistical analysis of concordance, validity, and reliability were performed. RESULTS: Reported major complications occurred in 332 patients (3.4%) with error in 78.3%: errors in surgical technique (63.5%), judgment errors (29.6%), inattention to detail (29.3%), and incomplete understanding (22.7%). Error contributed more than 50% to the complication in 75%. A total of 13.6% of cases had error but no injury, 34.4% prolongation of hospitalization, 25.1% temporary disability, 8.4% permanent disability, and 16.0% death. In 20%, the error was a "mistake" (the wrong thing), and in 58% a "slip" (the right thing incorrectly). System errors (2%) and communication errors (2%) were infrequently identified. CONCLUSIONS: After surgical technique, most surgical error was caused by human factors: judgment, inattention to detail, and incomplete understanding, and not to organizational/system errors or breaks in communication. Training efforts to minimize error and enhance patient safety must address human factor causes of error.

Regulation of atrial natriuretic peptide secretion by cholinergic and PACAP neurons of the gastric antrum.

Atrial natriuretic peptide (ANP) released from enterochromaffin cells helps regulate antral somatostatin secretion, but the mechanisms regulating ANP secretion are not known. We superfused rat antral segments with selective neural agonists/antagonists to identify the neural pathways regulating ANP secretion. The nicotinic agonist 1,1-dimethyl-4-phenylpiperazinium (DMPP) stimulated ANP secretion; the effect was abolished by hexamethonium but doubled by atropine. Atropine's effect implied that DMPP activated concomitantly cholinergic neurons that inhibit and noncholinergic neurons that stimulate ANP secretion, the latter effect predominating. Methacholine inhibited ANP secretion. Neither bombesin nor vasoactive intestinal polypeptide stimulated ANP secretion, whereas pituitary adenylate cyclase-activating polypeptide (PACAP)-27, PACAP-38, and maxadilan [PACAP type 1 (PAC1) agonist] each stimulated ANP secretion. The PAC1 antagonist M65 1) abolished PACAP-27/38-stimulated ANP secretion; 2) inhibited basal ANP secretion by 28 +/- 5%, implying that endogenous PACAP stimulates ANP secretion; and 3) converted the ANP response to DMPP from 109 +/- 21% above to 40 +/- 5% below basal, unmasking the cholinergic component and indicating that DMPP activated PACAP neurons that stimulate ANP secretion. Combined atropine and M65 restored DMPP-stimulated ANP secretion to basal levels. ANP secretion in the antrum is thus regulated by intramural cholinergic and PACAP neurons; cholinergic neurons inhibit and PACAP neurons stimulate ANP secretion.
