Evaluating how electronic charting affects resident productivity

Electronic medical records (EMRs) are becoming standard to improve the communication of information and longevity of patient records. Using an EMR in the emergency department (ED) could potentially slow residents evaluating patients. We evaluated how introducing an EMR affected resident productivity in an academic ED. We retrospectively studied first year emergency medicine residents from a large, academic, tertiary care center before-and-after the institution of an EMR on July 1st, 2010. No residents from the 2009–2010 class used the EMR, while all of the 2010–2011 residents used the EMR. We performed univariate and multivariate analyses using productivity, measured in patients per hour (pt/hr), as the primary outcome. A mixed-model multivariate regression, stratified by acuity zone, was created incorporating EMR and other possible confounders: admissions, signouts, daily ED volume, and days after July 1st for each shift. The study was granted IRB waiver of informed. We reviewed 2,405 shifts: 1,259 shifts before and 1,146 shifts after EMR implementation. When using the EMR, the univariate analysis estimated a 0.084 pt/hr increase in the high acuity zone (p = 0.1317) and 0.029 pt/hr decrease (p = 0.7085) in the low acuity zone. The multivariate regression estimated a 0.038 pt/hr increase (p = 0.3413) in the high acuity zone and a 0.009 pt/hr increase (p = 0.9049) in the low acuity zone with the EMR. Despite the expectation that electronic charting is detrimental to resident productivity, our analyses do not suggest a significant relationship between resident productivity and using the EMR.     

Rudolf Virchow: The physician as politician

Rudolf Virchow's life is an eloquent instance of the way professional and political activities can and should be integrated, if physicians are to live up to the highest ideals of the profession. At one and the same time father of pathology and father of social medicine, Virchow carried the results of his research to the public arena by advocating such measures as medical care for the poor, compulsory meat inspection to eliminate trichinosis, and the improvement of public sanitation. Elected to public office, Virchow led the protest against Bismarck's militarism despite the personal risk involved. His disarmament resolution, had it been accepted, might have averted the tragic Franco‐Prussian War of 1870.

Few of us can match his scientific accomplishments. Every physician can be inspired by his personal courage and his commitment to humane values. No task can be higher on the agenda of medicine than the defence of peace, the precondition for health in the nuclear era.

Epidemiologic Survillance of Cardiovascular Disease Mollar G, Cavalieri L, Galarza C, Waisman G, Beratarrechea A, Petrlik E, Langlois E, Soriano F, Marchetti M, and Gonzalez B de Quirós F Programas Médicos de Plan de Salud del Hospital Italiano de Buenos Aires

To enhance efficacy of health care, surveillance activities are required, especially with chronic prevalent diseases. Epidemiologic surveillance allows US to quantify and qualify health problems, settle priorities, identify high risk groups, manage and monitor health care systems, detect frequency changes in events, and assess performance of prevention and disease management programs. We have developed a surveillance system that identifies and reports daily on patients having cardiovascular disease (CVD) who are uncontrolled.

Objective: To evaluate the accomplishment of blood pressure (BP) measurement in people with CVD belonging to a health care system included in an epidemiological surveillance list.

Design: Cohort study between 1/1/2004 and 9/1/2004.

Methods: Patients 60 years old or older identified by surveillance system during the first term of 2004, were followed up. Patients were identified as having CVD through electronic medical record using international classification for primary attention (ICPA).

Patients are reported by the software system when presenting any of the following criteria: no blood pressure record during the past 6 months, blood pressure above 140/90 in the last record, and if diabetic A1C above 7.5%.

The connection with the appointment system allowed us to detect previously the patient’s attendance and, 15 min before his or her medical appointment, send the patient to be examined by the executors of a chronic disease program, according to the JNC VII guidelines.

The BP measurement is a common intervention to most chronic diseases because it increases cardiovascular risk, hence it is considered a process indicator of the surveillance system.

Results: Of the 24,411 patients having CVD, 5506 (26%) were listed during the first term, mean age was 74 years and 65% were female. By the end of 2004, 4660 (85%) patients had blood pressure recorded with an average values of 136.76 mmHg for systolic and 77.51 for diastolic blood pressure. Blood pressure was assessed three times in average.

Conclusion: Surveillance system allowed identifying of and intervening in a high proportion of patients.     

Peroxyacetyl Nitrate Inhalation

The eyes of rhesus monkeys and humans were exposed to long-pulsed ruby and neodymium, Q-switched ruby and neodymium, and helium-neon (He-Ne) lasers to determine retinal damage thresholds. Rabbit eyes were exposed to a carbon dioxide (CO₂) laser to determine corneal damage thresholds. The data were gathered simulating accidental field exposures.

The experimental data show that the white human fundus is appreciably less sensitive to damage from laser radiation compared to the rhesus monkey fundus. In general, the human threshold data obtained are considerably higher than some of the recommended safe levels.

Corneal damage levels caused by CO₂ laser radiation were reported. The data were shown to be consistent with a simple thermal model.

We emphasize that we are presenting experimental observations and are not recommending energy levels for “safe” laser exposures.     

Being born and growing up in the Ribeirão Preto and São Luís cohorts

This thematic issue consists of 14 articles derived from studies of the BRISA birth cohort (Ribeirão Preto, State of São Paulo and São Luís, State of Maranhão, northeastern Brazil, a socially and economically less developed region). In these more than 40 years of existence, these cohorts have been able to document the increase in women''s education, the improvement of health conditions, the creation of a public Unified Health System (SUS) that provides universal and free access to health care, eradication of hunger, and transition of the nutritional status characterized by a decrease in malnutrition rates and an increase in obesity in Brazil. Particularly in reproductive health, the country experienced a significant drop in fertility, a decrease in maternal and child mortality, and an increase in breastfeeding rates. Universal access to prenatal care and hospital delivery was accompanied by an excessive number of cesareans without clinical indication and early-term births and premature births, largely due to scheduled cesareans. Articles with a longitudinal and transversal methodological approach are presented, using structural equation analysis and propensity score, together with multivariate regressions, which gave a robust analytical treatment to articles in this thematic issue.     

Use of bilayer matrix wound dressing in the exenterated socket

To describe the novel use of a bilayer dermal substitute to reconstruct exenterated orbits. A retrospective chart review was performed in the practices of two surgeons (RET and PDL) of all patients who had undergone orbital exenteration between April 2014 and June 2016 and whose subsequent reconstruction included lining the socket with Integra bilayer. Patient demographics, pathologic diagnoses, surgical and post-operative complications, graft integrity, and patient acceptance were recorded. The charts of 7 patients (4 men and 3 women, ages 60–87 years) were reviewed. In all cases, the Integra graft had taken well to the socket bed at the time of silicone removal 3-4 weeks after surgery. Epithelialization of the socket occurred rapidly over the Integra graft (within several weeks) without incident in each case and with minimal postoperative management. No intraoperative or postoperative complications were noted. Integra dermal substitute is an ideal graft for the lining of an exenterated orbit. It is readily available in large quantities, handles easily, lines the socket smoothly, epithelializes rapidly, and requires minimal postoperative care. It offers minimal morbidity compared to skin grafting or free flap reconstruction, but greatly speeds epithelialization compared to laissez faire management. Surgeons should consider reconstructing exenterated orbits with the Integra matrix, both for its ease of use and its ability to epithelialize rapidly.     

Birth prevalence and characteristics of congenital toxoplasmosis in Sergipe,North‐east Brazil

Objectives To estimate, by neonatal screening, the birth prevalence of congenital toxoplasmosis among live‐born infants in Sergipe state, Brazil, and to investigate the clinical features of affected infants. Methods Dried blood spot specimens obtained from 15 204 neonates were assayed for the presence of anti‐T. gondii IgM antibodies. Duplicate retesting was done in infants with positive and borderline results. Confirmatory testing in peripheral blood samples consisted of testing for anti‐T. gondii IgG and IgM in infants and mothers. Those with possible congenital toxoplasmosis were evaluated and followed up to a median age of 20 months. Congenital infection was confirmed in the presence of persisting anti‐T. gondii IgG antibodies beyond 12 months of age. All infants with confirmed infection were treated with pyrimethamine, sulfadiazine and folinic acid for 1 year. Results Fifty‐three infants had detectable IgM in dried blood spot specimens. Confirmatory testing was reactive in 39/50, of which, 38 completed follow‐up. Six of 15 204 newborns were diagnosed with congenital toxoplasmosis, resulting in an estimated birth prevalence of four per 10 000 [CI 95% 1.4–8.0]. Four infants (67%) showed signs of congenital toxoplasmosis in their first year of life; three (75%) had retinochoroidal scars, and one had cerebral calcifications. Two infants remained asymptomatic until 20 months of age. Conclusions The birth prevalence of congenital toxoplasmosis is high in the Brazilian state of Sergipe, with most of the infants showing ocular lesions. Preventive measures are strongly warranted.
