Estimated height, weight, and body mass index: implications for research and patient safety.

BACKGROUND: Research suggests that weight influences patient care and outcomes. Health-care providers (HCPs) sometimes rely on patient self-reports or HCP estimates of height and weight. The purpose of this study was to determine the accuracy of self-reported height and weight and HCP estimations of height, weight, and body mass index (BMI) classification when compared with measured height, weight, and calculated BMI. STUDY DESIGN: Attending physicians, residents, and nurses provided height and weight estimates along with BMI categorizations for 110 trauma patients at a large, teaching hospital with a Level I trauma center. Patients provided reports of their heights and weights. Measured heights and weights were obtained with appropriate calibrated devices, and BMIs were calculated. Estimates and categorizations were then compared with measured and calculated values. RESULTS: HCPs were 41% and 53% accurate in estimating height and weight, respectively. Self-reports had higher accuracy (69% and 92%, respectively) but still resulted in a BMI misclassification of 32%. Twenty-two percent of patient self-reports were unobtainable. When HCPs attempted to categorize a patient into a BMI group, the accuracy was 56%. Functioning, calibrated instruments for measuring height and weight were frequently unavailable in relevant hospital locations. CONCLUSIONS: This study demonstrated that HCPs' estimates of height, weight, and BMI category are highly inaccurate. Patient self-reports are better, but are unavailable at times. Objective measurements with calibrated instruments are necessary for accuracy in research studies and for patient safety in clinical practice. Efforts to ensure the availability of calibrated instruments may be necessary in the hospital setting.

Integrating midlevel practitioners into a teaching service.

Meeting the educational needs and requirements of surgical resident physicians while achieving optimal patient care is a challenge for program directors. Midlevel practitioners (MLPs) were employed by a large community teaching hospital to augment the surgical teaching service, to improve continuity of patient care, and to provide resident physicians with greater flexibility to participate in classroom, operative, and clinical educational experiences. The MLPs were carefully integrated into the surgical program by creating the necessary buy-in, developing positive relationships, decreasing resistance, and reinforcing acceptance when demonstrated. MLPs function at the level of junior resident physicians and are active participants in the teaching and evaluation process. Structurally, MLPs receive their assignments from and report to the chief resident physician, but are ultimately responsible to the program director. Instituting the program required providing financial justification to administration and flexibility in meeting the diverse needs of the four teams. As a result, surgical resident physicians have been sufficiently freed from service activities to be able to capitalize on learning activities that range from surgeries to conferences. MLPs can be integrated into a surgical teaching program and become a positive force in the education of resident physicians.

Prehospital rapid sequence intubation for head trauma: conditions for a successful program.

BACKGROUND: Recent reports have questioned the safety and efficacy of prehospital rapid sequence intubation (RSI) for patients with head trauma. The purpose of this study is to determine the rate of successful prehospital RSI, associated complications, and delays in transport of critically injured trauma patients treated by a select, well-trained group of paramedics with frequent exposure to this procedure and a rigorous quality control system. METHODS: A helicopter paramedic group's database of patient flight records (1999 to 2003) was merged with registry data of a suburban Level I trauma center. Both databases included comprehensive performance improvement data. After Institutional Review Board approval, data were analyzed to determine RSI success rate, impact on oxygenation, delays in transport and complications associated with attempted RSI. Attempted RSI was defined as any insertion of the laryngoscope into the oropharynx. RESULTS: In all, 1,117 trauma patients were transported. One hundred and seventy-five had attempted RSI (74% male, mean age 31.1 +/- 19.2 years, 91% blunt trauma, 88% with Head/Neck AIS >or=2, mean Injury Severity Score 25.6, mean scene Glasgow Coma Scale score 4.8 +/- 2.4). One hundred and sixty-nine patients (96.6%) had successful scene RSI. Seventy percent were intubated on the first attempt, 89% by the second attempt, and 96% by the third attempt. Of the six patients (3.4% overall) who failed RSI, (2.3% overall) had scene cricothyroidotomy and two (1.1% overall) were managed by bag-valve mask. Complications included five (2.9%) right mainstem intubations and 2 (1.2%) endotracheal tube dislodgments en route. There were no esophageal intubations. Four patients in extremis (2.3%) had arterial desaturations associated with RSI. Arterial blood gas analyzed upon arrival revealed (mean pCO2 36.6 +/- 8, median 37). Attempted RSI was associated with a mean of 6 minutes of added scene time. CONCLUSION: Prehospital RSI for trauma patients can be safely and effectively performed with low rates of complication and without significant delay in transport. This study suggests that resources for prehospital airway management should be focused on training, regular experience, and close monitoring of a limited group of providers, thereby maximizing their exposure and experience with this procedure. This is particularly important given the high rates of traumatic brain injury encountered.

RN-to-MSN students' attitudes toward women experiencing homelessness: A focus group study.

When health professionals, including RNs, have negative attitudes toward women experiencing homelessness, they create barriers to services. It is incumbent on nursing faculty to develop curricula that address homelessness and associated stereotypes, as well as to prepare students to provide safe and appropriate care to the homeless population. The aim of this qualitative study was to examine the attitudes of RN-to-MSN students toward mothers living with their children in a transitional shelter. A convenience sample of 10 students enrolled in a community health nursing course at a university in southern California participated in the study. Two focus groups were conducted: one before and one after a 15-week clinical experience. Data analysis revealed that during the clinical experience, students discovered that they, or perhaps an individual like them, could become homeless. Their attitudes and views changed to include a bigger picture of homelessness, described by public health nursing researchers as "moving upstream." This article suggests strategies for integrating clinical experiences with socioeconomically vulnerable individuals into undergraduate nursing curricula.

A survey of EAST member practices in blunt splenic injury: a description of current trends and opportunities for improvement.

BACKGROUND: The literature on blunt splenic trauma provides little evidence-based direction for nonsurgical management. The appropriate role of computed tomography (CT) after initial diagnosis, activity restriction and follow-up are continuing controversies. METHODS: Active EAST members were surveyed regarding in-hospital management and follow-up of patients with isolated and near-isolated blunt splenic injury. Analyses were performed using descriptive and correlational statistics. RESULTS: A 38.4% response rate was obtained. 82.6% of respondents practiced at a Level I trauma centers. 97% of respondents considered hemodynamic instability as the primary indication for immediate splenectomy. 71.6% of respondents preferred ultrasound for initial imaging in hemodynamically stable patients. One-third of respondents admitted stable Grade I patients to monitored settings. 85.5% would not routinely perform predischarge abdominal CT scan in the absence of clinical deterioration, extravasation on initial CT or high-grade injury. Activity restriction varied by grade (table). The majority of respondents (78.1%) relied on clinical judgment alone for activity recommendations in lower grades of injury while a higher reliance on CT was used for Grades IV and V (49.8%). CONCLUSIONS: Despite the lack of evidence-based guidelines, many in-hospital and follow-up practices were reasonably consistent. However, some important contradictions were noted (such as monitoring very low risk patients and not intervening in patients with contrast blush). Activity restrictions were usually based on clinical judgment supplemented by CT at the highest grades of injury. Lack of evidence-based guidelines and high reliance on clinical judgment underscore the need for a well-designed prospective study to define optimal management and follow-up.

Pretest prediction of BRCA1 or BRCA2 mutation by risk counselors and the computer model BRCAPRO.

BACKGROUND: Because BRCA gene mutation testing is costly, occasionally uninformative, and frequently associated with ethical and legal issues, careful patient selection is required prior to testing. Estimation of BRCA gene mutation probability is an important component of pretest counseling, but the accuracy of these estimates is currently unknown. We measured the performance of eight cancer risk counselors and of a computer model, BRCAPRO, at identifying families likely to carry a BRCA gene mutation. METHODS: Eight cancer risk counselors and the computer model BRCAPRO estimated BRCA gene mutation probabilities for 148 pedigrees selected from an initial sample of 272 pedigrees. The final sample was limited to pedigrees with a proband affected by breast or ovarian cancer and BRCA1 and BRCA2 gene sequencing results unequivocally reported as negative or positive for a deleterious mutation. Sensitivity, specificity, negative predictive value, positive predictive value, and areas under receiver operator characteristics (ROC) curves were calculated for each risk counselor and for BRCAPRO. All statistical tests were two sided. RESULTS: Using a greater-than-10% BRCA gene mutation probability threshold, the median sensitivity for identifying mutation carriers was 94% (range = 81% to 98%) for the eight risk counselors and 92% (range = 91% to 92%) for BRCAPRO. Median specificity at this threshold was 16% (range = 6% to 34%) for the risk counselors and 32% (range = 30% to 34%) for BRCAPRO (P =.04). Median area under the ROC curves was 0.671 for the risk counselors (range = 0.620 to 0.717) and 0.712 (range = 0.706 to 0.720) for BRCAPRO (P =.04). There was a slight, but not statistically significant, improvement in all counselor performance measures when BRCAPRO-assigned gene mutation probability information was included with the pedigrees. CONCLUSIONS: Sensitivity for identifying BRCA gene mutation carriers is similar for experienced risk counselors and the computer model BRCAPRO. Because the computer model consistently demonstrated superior specificity, overall discrimination between BRCA gene mutation carriers and BRCA gene mutation noncarriers was slightly better for BRCAPRO.

Palliative home nursing interventions for people with HIV/AIDS: a pilot study.

AIDS-related deaths have declined; however, AIDS prevalence has increased. People with advanced HIV/AIDS often require home health nursing care, yet little is known regarding the character and frequency of the nursing interventions required. Demographic, symptom, and nursing care data were collected on 26 HIV-positive patients receiving palliative home health services. Patients were taking an average of 33 pills daily, not including as-needed medications. They rated an average of 16 symptoms as moderate or severe. Content analysis of nurses' narrative descriptions of their interventions revealed that care is concentrated around physiologic monitoring and adapting the home care environment to assist patients to manage their medications.

Methamphetamine use and HIV symptom self-management.

This study describes HIV-related symptoms in a methamphetamine-using sample of 20 men living in southern California. Data were obtained in 2004 and 2005 using a cross-sectional design. Participants were administered the Revised Sign and Symptom Check-List for Persons With HIV Disease and the Addiction Severity Index and were engaged in a semistructured interview. Participants reported using methamphetamine to treat HIV-related depression, fatigue, and neuropathic pain. HIV-related diarrhea seemed to diminish with methamphetamine use, although this was not a motivation for use. These results, although preliminary, suggest that further study of the interplay between methamphetamine use and HIV symptom management is warranted.

Paramedic rapid sequence intubation for severe traumatic brain injury: perspectives from an expert panel.

Although early intubation has become standard practice in the prehospital management of severe traumatic brain injury (TBI), many patients cannot be intubated without neuromuscular blockade. Several emergency medical services (EMS) systems have implemented paramedic rapid sequence intubation (RSI) protocols, with published reports documenting apparently conflicting outcomes effects. In response, the Brain Trauma Foundation assembled a panel of experts to interpret the existing literature regarding paramedic RSI for severe TBI and offer guidance for EMS systems considering adding this skill to the paramedic scope of practice. The interpretation of this panel can be summarized as follows: (1) the existing literature regarding paramedic RSI is inconclusive, and apparent differences in outcome can be explained by use of different methodologies and variability in comparison groups; (2) the use of Glasgow Coma Scale score alone to identify TBI patients requiring RSI is limited, with additional research needed to refine our screening criteria; (3) suboptimal RSI technique as well as subsequent hyperventilation may account for some of the mortality increase reported with the procedure; (4) initial and ongoing training as well as experience with RSI appear to affect performance; and (5) the success of a paramedic RSI program is dependent on particular EMS and trauma system characteristics.
