A program to enhance recruitment and retention of disadvantaged and ethnically diverse baccalaureate nursing students.

PURPOSE: To describe and evaluate the use of a "Success in Learning: Individualized Pathways Program (SLIPP)" to retain and graduate disadvantaged and ethnically diverse nursing students. DESIGN: A summative evaluative design was used with a population of 77 disadvantaged and ethnically diverse students who were accepted into a pre-entrance preparation quarter. The program based on an academic success model, included six pre-entrance classes, academic, social, and financial support, and seven faculty development workshops. Program outcomes were studied using student records, survey results, and interviews. RESULTS: Following the pre-entrance quarter, all 77 students were accepted into the baccalaureate nursing program, 90.9% graduated with either a Bachelor in Science (75.3%) or Associate in Science (15.6%), and 98.6% of the graduates passed the state board registered nursing examination. DISCUSSION: Outcomes are discussed in light of similar programs. CONCLUSIONS: Underprepared disadvantaged and ethnically diverse students can successfully become registered nurses. IMPLICATIONS: Educators and recruiters for nursing practice should accept/hire culturally diverse students/nurses to expand the ethnic diversity of the nursing workforce to meet the needs of culturally diverse clients. Research is needed to determine the classes/components and length of the pre-entrance preparation program to successfully enhance success.

Three-percent saline administration during pediatric critical care transport.

OBJECTIVES: The purpose of this study was to describe the administration of 3% saline (3%S) during pediatric critical care transport. METHODS: A retrospective study was performed on pediatric patients who underwent critical transport to Loma Linda University Children's Hospital from January 1, 2003, to June 30, 2007, and were given 3%S. Patients' demographics, admission diagnosis, route and amount of 3%S administration, serum electrolytes, vital signs, radiographic data, and Glasgow Coma Scale scores were collected and analyzed. RESULTS: A total of 101 children who received 3%S infusions during pediatric critical care transport were identified. Mean patient age was 5.9 years, and mean patient weight was 27.6 kg. The main indications for infusing 3%S were suspected cerebral edema (41%), intracranial bleed with edema (51%), and symptomatic hyponatremia (6%). The amount of 3%S bolus ranged from 1.2 to 24 mL/kg, with a mean of 5.4 mL/kg. Serum electrolytes before and after 3%S infusion demonstrated significant increases in sodium, chloride, and bicarbonate levels (P < 0.05). A significant reduction was also seen in serum urea nitrogen levels and anion gap. Radiographic imaging performed before 3%S infusion demonstrated findings consistent with concerns of increased intracranial pressure such as intracranial bleed and cerebral edema. The route of initial 3%S infusions was mainly through peripheral intravenous lines (96%). No complications related to the 3%S delivery such as local reactions, renal abnormalities, or central pontine myelinolysis were observed. CONCLUSIONS: It seems 3%S may be administered safely during pediatric critical transport and administration routes can include peripheral lines. With the importance of initiating therapy early to improve patient outcomes, the use of 3%S may benefit transported children with brain injury and suspected intracranial hypertension.

Prospective randomized evaluation of short-term complications when using buffered or unbuffered lidocaine 1% with epinephrine for blepharoplasty surgery.

PURPOSE: To determine whether there is a difference in the incidence of short-term complications using plain lidocaine with epinephrine versus the buffered equivalent in eyelid surgery. METHODS: The authors performed a prospective, double-masked, randomized study in patients scheduled for combined upper eyelid blepharoplasty and levator advancement ptosis repair surgery with local anesthesia. Exclusion criteria included: documented allergies to lidocaine and/or epinephrine; known pregnancy; profound cognitive impairment; inability to understand the visual analog scale or the informed consent; and previous eyelid surgery. Each subject was his/her own control by using the unbuffered local anesthetic in one eye, while the buffered solution was used in the other eye. The surgeon completed a specific standardized data collection form for quantifying both intraoperative and postoperative complications, such as bleeding, bruising, and edema. Data regarding pain on injection and postoperative pain were collected from patients using a visual analog pain scale. RESULTS: Thirty-nine patients were included in this study, of which 18 experienced less pain during the injection on the side where buffered lidocaine was used, 11 reported no difference, and 10 reported less pain in the eye injected with unbuffered lidocaine. Injection pain revealed a mean operative pain rating of 4.01 +/- 2.45 in the eye with buffered lidocaine versus 4.49 +/- 2.58 in the control (p = 0.06). There were no significant differences between the buffered and unbuffered lidocaine eyes as regards postoperative bleeding, swelling, or pain, and there was a trend toward less pain on injection with the buffered solution. CONCLUSIONS: There were no significant differences in postoperative pain, swelling, or bleeding with the use of plain versus buffered lidocaine in eyelid surgery. There was a trend for the buffered anesthetic to cause less pain on injection.

Comparison of a novel one-step percutaneous nephrolithotomy sheath with a standard two-step device.

OBJECTIVES: Percutaneous nephrolithotomy (PCNL) is the treatment of choice for large renal calculi. The most widely used access sheath for PCNL involves two steps including placement of a high-pressure balloon catheter (HPBC) followed by advancement of a sheath over the balloon. A novel PCNL balloon/sheath combination (NSS) has been developed that allows for both dilation and sheath placement in a single step. The objective of this study was to compare the safety and efficacy of the NSS to the HPBC in a porcine model. METHODS: Six farm pigs underwent placement of a standard HPBC in one kidney and the NSS on the contralateral side. We obtained access in the upper pole in 2 animals, middle pole in 2 animals, and lower pole in 2 animals. We obtained data on insertion time, difficulty of insertion, estimated blood loss (EBL), ability to visualize the collecting system, and gross and histopathologic analysis. RESULTS: There was no statistical difference in degree of difficulty in placing the NSS (3 easy, 3 moderate) versus HPBC device (1 easy, 5 moderate; P = 0.07), estimated blood loss (P = 0.10), or the ability to visualize the collecting system (P = 0.32). There was a significantly shorter insertion time in the NSS group compared with the HPBC group (1:37 versus 2:26 minutes, P = 0.04). CONCLUSION: This study demonstrates that the NSS is safe and effective in the porcine model. Trials in patients are currently under way.

Comparing immersion ultrasound with partial coherence interferometry for intraocular lens power calculation.

BACKGROUND AND OBJECTIVE: To compare the utility and accuracy of high-precision immersion ultrasound, partial coherence interferometry, and the IOL Master system (Carl Zeiss Meditec, Dublin, CA) in a tertiary care referral center. PATIENTS AND METHODS: Comparative clinical study in a tertiary care, multispecialty, university practice. Participants were consecutive patients scheduled for cataract surgery at Emory Eye Center. Patients underwent biometry using immersion ultrasound, partial coherence interferometry, and the IOL Master system. RESULTS: Twenty-two percent of eyes undergoing surgery could not be measured using interferometry. In those eyes measurable by both methods, there was no difference in measurements nor postoperative refractive outcome. Each method had a high repeatability (intraclass correlation coefficient > 0.99) with a high intraclass correlation between methods (intraclass correlation coefficient = 0.99). CONCLUSIONS: When it can be used, interferometry is equivalent to immersion ultrasonography regarding biometric accuracy and precision. However, it cannot replace ultrasonography, especially for eyes with dense media opacity.

Mechanisms of hemostatic failure during laparoscopic nephrectomy: review of Food and Drug Administration database.

OBJECTIVES: To compare the complications with endovascular stapling devices, nonlocking titanium clips, and nonabsorbable polymer ligating (Hem-o-lok) clips during laparoscopic nephrectomy. METHODS: The Food and Drug Administration Manufacturer and User Facility Device Experience Database was retrospectively reviewed for reports dated from January 1992 to March 2006 using the key words "nephrectomy" and "kidney." All episodes of pure and hand-assisted laparoscopic nephrectomy were evaluated. RESULTS: Of 2172 total nephrectomy or kidney-related reports, 352 reported failure using laparoscopic hemostatic devices to secure the renal vasculature, and 223 complications (63%) resulted during the use of endovascular stapling devices, 111 (33%) from nonlocking titanium clips and 18 (5%) from locking clips. The leading causes of failure reported in stapling devices were staple line malformation (47%) and locking up (29%). In titanium clips, jamming/feeding difficulties (27%) and trouble closing or "scissoring" clips (26%) were the most common. In locking clips, dislodgement (44%) was most frequently reported. Three, one, and three deaths were reported after the use of the stapling device, titanium clip, and locking clip device, respectively. CONCLUSIONS: All three methods used to secure the renal hilum in laparoscopic nephrectomy can result in malfunction. Because the overall denominator of use is not known, it would be inappropriate to conclude that one device is safer than another. When they occurred, these device malfunctions were potentially serious. Knowledge of the possible mechanisms of failure seen with each device could allow surgeons to anticipate potential complications and, therefore, perform laparoscopic surgery more safely.

The effect of anterior versus posterior glide joint mobilization on external rotation range of motion in patients with shoulder adhesive capsulitis.

STUDY DESIGN: Randomized clinical trial. OBJECTIVE: To compare the effectiveness of anterior versus posterior glide mobilization techniques for improving shoulder external rotation range of motion (ROM) in patients with adhesive capsulitis. BACKGROUND: Physical therapists use joint mobilization techniques to treat motion impairments in patients with adhesive capsulitis. However, opinions of the value of anterior versus posterior mobilization procedures to improve external rotation ROM differ. METHODS AND MEASURES: Twenty consecutive subjects with a primary diagnosis of shoulder adhesive capsulitis and exhibiting a specific external rotation ROM deficit were randomly assigned to 1 of 2 treatment groups. All subjects received 6 therapy sessions consisting of application of therapeutic ultrasound, joint mobilization, and upper-body ergometer exercise. Treatment differed between groups in the direction of the mobilization technique performed. Shoulder external rotation ROM measured initially and after each treatment session was compared within and between groups and analyzed using a 2-way ANOVA, followed by paired and independent t tests. RESULTS: There was no significant difference in shoulder external rotation ROM between groups prior to initiating the treatment program. A significant difference between groups (P = .001) was present by the third treatment. The individuals in the anterior mobilization group had a mean improvement in external rotation ROM of 3.0 degrees (SD, 10.8 degrees; P = .40), whereas the individuals in the posterior mobilization group had a mean improvement of 31.3 degrees (SD, 7.4 degrees; P < .001). CONCLUSIONS: A posteriorly directed joint mobilization technique was more effective than an anteriorly directed mobilization technique for improving external rotation ROM in subjects with adhesive capsulitis. Both groups had a significant decrease in pain.

Laparoscopic warm renal ischemia in the solitary porcine kidney model.

OBJECTIVES: To determine the effect of a laparoscopic approach on warm renal ischemia in the pig with a solitary kidney. Although the maximal safe duration for warm ischemia during open partial nephrectomy is commonly accepted to be 30 minutes, the maximal safe ischemic time during laparoscopic partial nephrectomy has not been previously determined. METHODS: Sixteen farm pigs underwent unilateral laparoscopic right nephrectomy. Two weeks later, the pigs underwent complete laparoscopic mobilization of the remaining left kidney and were randomized to complete hilar clamp times of 0, 30, 60, or 90 minutes. Serum creatinine was evaluated before right nephrectomy and at days 0, 2, 4, 7, 14, and 30 after renal ischemia during laparoscopy. All renal specimens were evaluated by an experienced nephropathologist in a blinded fashion. RESULTS: The serum creatinine remained stable at all points in the control and 30-minute ischemia groups. The serum creatinine level rose initially on days 2 and 4 in the 60-minute and 90-minute ischemia groups but returned to baseline by day 7. At harvest, no statistically significant difference was found among the groups in serum creatinine or histologic features. CONCLUSIONS: Renal ischemic times up to 90 minutes during laparoscopy were well tolerated by the solitary porcine kidney. Possible explanations for this finding include the protective effect of a solitary kidney and the potential protective effect of relative ischemic preconditioning provided by the pneumoperitoneum.

Practice analysis: defining the clinical practice of primary contact physical therapy.

STUDY DESIGN: Nonexperimental descriptive research design. OBJECTIVE: To describe the frequency of use and perceived level of importance of professional responsibilities, procedures, and knowledge areas by physical therapists practicing in primary contact care settings and to compare these data to similar data from physical therapists practicing in nonprimary contact care settings. BACKGROUND: Physical therapy services have moved toward a primary contact model of practice in response to changes in the health care delivery system. Several studies have reported the effectiveness of primary contact physical therapy. However, a practice analysis has not been performed to define the clinical practice of primary contact physical therapy. METHODS AND MEASURES: A sample of 212 physical therapists practicing as primary contact providers in the military and civilian sectors, and a comparison group of 250 physical therapists not practicing as primary contact providers were surveyed. A Delphi technique was used to develop the survey instrument, which was pretested by a pilot group. The final survey instrument consisted of 171 items. Chi-square and Kruskal-Wallis tests were conducted to examine significant differences among the 3 groups (P<.001). RESULTS: Of the 212 surveys mailed to the primary contact group, 119 (56.1%) responses were received (82 military physical therapists and 37 civilian physical therapists). Of the 250 surveys mailed to the comparison group, 103 (41.2%) responses were received. There were numerous significant differences among the 3 groups in professional responsibilities, procedures, and knowledge areas, most notably in the areas of selecting and ordering of imaging procedures, identifying signs and symptoms of nonmusculoskeletal conditions, establishing physical therapy diagnoses, and prescribing over-the-counter medications. CONCLUSION: The study describes the clinical practice of physical therapists functioning in the role of primary contact providers or as members of a diverse team of health care professionals in primary care, which may provide curricular direction to professional, postprofessional, and clinical residency or fellowship-based educational settings.

Disability self-assessment and upper quarter muscle balance between female dental hygienists and non-dental hygienists.

PURPOSE: The purpose of this pilot study was to compare disability self-assessment and upper quarter muscle balance female dental hygienists and non dental hygienist females. The upper quarter was operationally defined as the shoulder and neck region. Muscle balance was operationally defined as muscle flexibility and muscle performance. METHODS: A convenience sample of 41 working dental hygienists and 46 non dental hygienists participated in the study. Muscle flexibility of the upper quarter was measured by inclinometry or standard muscle length testing. Muscle performance was measured by timing the duration of four statically maintained positions. Subjects filled out the Northwick Park Neck Pain Questionnaire (NPNPQ), which is a disability self-assessment. Analysis of Covariance (ANCOVA) was used during data analysis to adjust for the mean age difference between the dental hygienist group (38.0 years) and the non-dental hygienist group (29.3 years). RESULTS: The results of this pilot study suggest that female dental hygienists are more likely than non dental hygienist females to develop tightness in the upper trapezius (p = 0.007) and the levator scapula (p = 0.01) of the non dominant upper quarter and lower fibers of the pectoralis major of the dominant upper quarter (p = 0.03) Muscle performance trends in the dental hygienist group supported muscle balance theory that short muscles remain strong while lengthened muscles become weak. The dental hygienist group had higher disability scores in all nine parts of the NPNPQ compared to the non-dental hygienist group, five of which were statistically significant (p < 0.05). CONCLUSION: The results of this pilot study suggest that muscle imbalances in the upper quarter are more common in female dental hygienists than in female non dental hygienists and may contribute to the numerous upper quarter pathologies associated with the practice of dental hygiene. Further research is needed to determine if upper quarter strengthening and flexibility exercises performed by dental hygienists can reduce disability self-assessment.

Duration of graft cold ischemia does not affect outcomes in pediatric heart transplant recipients.

BACKGROUND: Utilizing donor hearts with prolonged graft ischemia may extend the donor pool. METHODS AND RESULTS: The medical records of 363 infants and children, aged 1 day to 17 years, transplanted at Loma Linda University between November 1985 and March 2001, were retrospectively reviewed. Fourteen children received organs with prolonged ischemic times (>8 hours)(PIT) compared with 14 with short ischemic times (< or =90 minutes)(SIT). There were no significant differences when comparing donors for gender, age, weight, cause of death, or duration of cardiopulmonary resuscitation. Preoperative donor shortening fraction (%), as determined by echocardiography, was significantly higher in the SIT group (44.5 versus 36.5%; P=0.006). There were no significant differences between PIT and SIT recipients when comparing age at transplant, weight at transplant, waiting time, weight mismatch, postoperative days on ventilator, duration of inotropic support, and hospital stay. Cardiopulmonary bypass time was significantly longer in the PIT group (140.5 versus 80.5 minute; P=0.001). Median length of follow-up for both groups was approximately 5 years. Five grafts were lost in the PIT group; 7 were lost in the SIT group, with 1 early graft loss in each group. Significant posttransplant coronary artery disease was diagnosed in 2 recipients in each group (PIT: 80 and 42; SIT: 84 and 67 months posttransplant). There was no significant difference between groups in actuarial graft survival. Number of rejection episodes and hospital readmissions during the first posttransplantation year did not differ significantly between groups. CONCLUSION: Late outcomes were not adversely affected by donor hearts preserved by single dose cold crystalloid cardioplegia with greater than 8 hours of cold ischemia.
