OBJECTIVES: To assess differences in diabetes processes of care among Chinese and Latino patients across medical interpreting methods. DESIGN AND SETTING: This is a nested cohort study of patients with diabetes, comparing interpreting methods and their impact on medical outcomes at the primary care clinic of a New York City municipal hospital. PARTICIPANTS: 54 Spanish and Chinese-speaking language discordant diabetic patients were enrolled and followed for one year. INTERVENTION: Language discordant patients received either Remote Simultaneous Medical Interpreting (RSMI), or usual and customary (U&C) interpreting. MAIN OUTCOME MEASURES: Composite medical care scores were calculated for physician ordering and patient completion of diabetes care measures. RESULTS: RSMI patients, compared with U&C patients, had trends towards higher mean patient completion (.29 vs .25) and physician ordering (.41 vs .37) scores. Overall rates of completion of diabetes care measures in both groups were very low. CONCLUSIONS: Overall rates of physician ordering and patient completion of diabetes care measures were distressingly low in our study. Further studies are needed to explore the potential role of RSMI in addressing the language barrier and improving diabetes care for Chinese- and Spanish-speaking patients.

Public health leaders, like physicians, need to make decisions that impact health based on strong evidence. To generate useful evidence for public health leaders, research must focus on interventions that have potential to impact population-level health. Often policy and environmental changes are the interventions with the greatest potential impact on population health, but studying these is difficult because of limitations in the methods typically used and emphasized in health research. To create useful evidence for policy and environmental interventions, other research methods are needed, including observational studies, the use of surveillance data for evaluation, and predictive mathematical modeling. More emphasis is needed on these types of study designs by researchers, funding agencies, and scientific journals.

OBJECTIVE: The aim of this study was to measure the effect of an electronic heparin-induced thrombocytopenia (HIT) alert on provider ordering behaviors and on patient outcomes. MATERIALS AND METHODS: A pop-up alert was created for providers when an individual's platelet values had decreased by 50% or to <100,000/mm(3) in the setting of recent heparin exposure. The authors retrospectively compared inpatients admitted between January 24, 2008 and August 24, 2008 to a control group admitted 1 year prior to the HIT alert. The primary outcome was a change in HIT antibody testing. Secondary outcomes included an assessment of incidence of HIT antibody positivity, percentage of patients started on a direct thrombin inhibitor (DTI), length of stay and overall mortality. RESULTS: There were 1006 and 1081 patients in the control and intervention groups, respectively. There was a 33% relative increase in HIT antibody test orders (p=0.01), and 33% more of these tests were ordered the first day after the criteria were met when a pop-up alert was given (p=0.03). Heparin was discontinued in 25% more patients in the alerted group (p=0.01), and more direct thrombin inhibitors were ordered for them (p=0.03). The number who tested HIT antibody-positive did not differ, however, between the two groups (p=0.99). The length of stay and mortality were similar in both groups. CONCLUSIONS: The HIT alert significantly impacted provider behaviors. However, the alert did not result in more cases of HIT being detected or an improvement in overall mortality. Our findings do not support implementation of a computerized HIT alert.

OBJECTIVES: (1) To describe a new protocol using nonopioid medications (clonidine, lorazepam, trazodone, and a stimulant) to successfully complete outpatient opioid detoxification, (2) to determine clinical and demographic characteristics of patients who successfully complete an outpatient opioid detoxification, and (3) to determine the safety and clinical utility of the use of this combination of medications in the treatment of opioid withdrawal. METHODS: In a posthoc evaluation study in a New York State-licensed outpatient detoxification unit of a substance abuse treatment facility, 223 heroin-dependent adults presenting for treatment were provided outpatient opioid detoxification. In the course of the opioid detoxification protocol of the facility, patients received clonidine, lorazepam, trazodone, and either a stimulant (methylphenidate or modafinil) or no stimulant, in combination on a daily basis. At each daily visit, signs and symptoms were assessed, and medications and dosing instructions were given for the following 24 hours. On completion of the detoxification protocol, patients were induced with oral naltrexone. RESULTS: Overall, 61.0% (136) of the patients in this study successfully completed the outpatient detoxification protocol and were induced with naltrexone. Pretreatment demographic variables that predicted successful treatment included full-time employment, family support, private medical insurance, and referral by an employee assistance program. About 77% of patients with good prognosis successfully completed outpatient detoxification treatment. The addition of a stimulant improved patient retention and reduced the incidence of hypotension. CONCLUSIONS: The outpatient detoxification of opioid-dependent patients without the use of opioids has traditionally led to such high drop out rates that most clinical programs do not even consider the option. This makes it difficult to induce patients with opioid antagonists such as oral naltrexone or sustained release naltrexone. We describe a protocol here that leads to excellent rates of successful detoxification. This nonopioid detoxification methodology permits induction of naltrexone without the delay experienced in opioid-based titrations, and it thus facilitates the use of opioid antagonists for sustained abstinence, enhanced aftercare treatment outcomes, and opioid-free recovery.

Background: Contiguous gene deletion of the Wilms tumor gene (WT1) is associated with two well described syndromes; Denys-Drash (DDS) and Frasier (FS). Both are associated with nephropathy and ambiguous genitalia and have overlapping clinical and molecular features (1). The known risk of Wilms tumors in DDS and gonadoblastomas in FS patients requires tumor surveillance.Case report: We evaluated a newborn with ambiguous genitalia, intact Mullerian structures (uterus) and small bilateral perivesicular gonads with a 46,XY (SRY+) karyotype. The physical exam revealed labia with clitoromegaly (1.2 cm in length). There were separate uretheral and vaginal openings with no urogenital sinus. Labs in the early neonatal period (Quest Diagnostics: all male references) revealed 17-OH-Progesterone 96 (<420 ng/dL), testosterone 133 (2-23 ng/dL; tanner 1), DHEAS 441 (73-367 ug/dL), inhibin A <1 (<21 pg/mL; prepubertal), inhibin B 35 (<161 pg/mL; 3-9 years old), and AMH 3.7 (87.3-243 ng/mL; 1-6 years old). After a joint discussion with the family, geneticist, endocrinologist, and psychologist the infant was assigned a female gender. Based on the phenotype (ambiguous genitalia, pre and postnatal hydronephrosis, and genitourinary abnormalities), the exon and exon-intron boundaries were sequenced. A missense mutation leading to the substitution of lysine for glutamine at position 369 of the WT1 protein (Q369K) in exon 8 was found to be consistent with Denys-Drash syndrome. At seven months of age the patient underwent a clitoroplasty and gonadectomy. Bilateral gonadoblastomas were found in an indeterminate left gonad and a right testis. In addition, the patient had bilateral grade 2-3 vesicoureteral reflux and progressed to end stage renal failure at 11 months of age (creatinine 1.4mg/dl). Consequently, the patient has secondary hyperparathyroidism with PTH 691 (12-65 pg/mL), calcium 7.2 (8-10.4 mg/dL), and phosphorus 7 (2.7-4.5 mg/dL). The patient's most recent renal ultrasound does not show evidence of a Wilms tumor (2).Conclusion: This is one of the earliest cases of bilateral gonadoblastoma reported in DDS. This case highlights the importance of early gonadectomy at the time of diagnosis of the WT1 gene mutation as these tumors have potential for malignant transformation

Men who have sex with men (MSM) represent more than half of all new HIV infections in the United States. Utilizing a collaborative, community based approach, a brief risk reduction intervention was developed and pilot tested among newly HIV-diagnosed MSM receiving HIV care in a primary care setting. Sixty-five men, within 3 months of diagnosis, were randomly assigned to the experimental condition or control condition and assessed at baseline, 3-month, and 6-month follow-up. Effect sizes were calculated to explore differences between conditions and over time. Results demonstrated the potential effectiveness of the intervention in reducing risk behavior, improving mental health, and increasing use of ancillary services. Process evaluation data demonstrated the acceptability of the intervention to patients, clinic staff, and administration. The results provide evidence that a brief intervention can be successfully integrated into HIV care services for newly diagnosed MSM and should be evaluated for efficacy.

OBJECTIVE: This project sought to describe unmet needs among patients reported with hepatitis C in New York City. DESIGN: From the New York City Health Department's hepatitis C surveillance database, we randomly selected patients whose positive hepatitis C test was in April or May 2005. In 2006, we interviewed patients by telephone and collected information from their clinicians or by medical record review. SETTING: New York City. PARTICIPANTS: We interviewed 180 of the 387 eligible patients and collected information from clinicians for 145 of the 180 patients. MAIN OUTCOME MEASURES: These included whether patients had understood their clinicians' explanation of their hepatitis C diagnosis, if they had been counseled about not drinking alcohol, information about support group attendance, vaccination against hepatitis A and B, health status, treatment, and other factors. RESULTS: Of the 180 patients, 7% stated that they had not understood their clinicians' explanation of their hepatitis C diagnosis, and 26% said that they had not been counseled about avoiding alcohol. Among the 90% of patients who had not attended a hepatitis support group, 31% were interested in attending. Among the 145 patients with information from clinicians, at least 28% were susceptible to hepatitis A and 18% to hepatitis B. CONCLUSIONS: This hepatitis C surveillance project, with information from patients and clinicians, illustrates a valuable use of a chronic hepatitis C surveillance system. The patients described here had several unmet needs, including hepatitis A and B vaccination, basic information about the virus, support groups, and counseling about preventing further liver damage and preventing transmission to others. Relatively simple and affordable health department activities can address these needs, improving quality of life and decreasing the likelihood of liver disease progression.

AIMS: This paper is a report of a descriptive comparative pilot study of use of a method that simultaneously tests the content validity and quality of translation of English-to-Chinese translations of two patient satisfaction questionnaires: the La Monica-Oberst Patient Satisfaction Scale and Hospital Consumer Assessment of Healthcare Providers and Systems. BACKGROUND: Patient satisfaction is an important indicator of the quality of healthcare services. In China, however, few good translations of patient satisfaction instruments sensitive to nursing services exist. METHODS: The descriptive pilot study took place in 2009 and used content validity indexing techniques to evaluate the content, context and criterion relevance of a survey question. The expert raters were 10 nursing faculty and 10 patients who evaluated the two patient satisfaction questionnaires. The experts evaluated the relevance of each item on a scale of 1-4 and the research team compared their responses to choose the most appropriate. Only the nurse faculty experts, who were bilingual, evaluated the quality of the translation using a binary rating. RESULTS: The 'Nurse Rater' relevance scores of the LaMonica-Oberst Patient Satisfaction Scale and the Hospital Consumer Assessment of Healthcare Providers and Systems were 0.96 and 0.95 respectively, whereas the patient's overall relevance scores were 0.89 and 0.95. A Mann-Whitney U-test demonstrated that results between the two groups were statistically significantly different (P = 0.0135). CONCLUSIONS: Using content validity indexing simultaneously with translation processes was valuable for selecting and evaluating survey instruments in different contexts.

OBJECTIVES: Gastroenterology (GI) training programs are mandated to teach fellows interpersonal communication and professionalism as basic competencies. We sought to assess important skill sets used by our fellows but not formally observed or measured: handoffs, telephone management, and note writing. We designed an Observed Standardized Clinical Examination (OSCE) form and provided the faculty with checklists to rate fellows' performance on specific criteria. METHODS: We created two new scenarios: a handoff between a tired overnight senior fellow on call and a more junior fellow, and a telephone management case of an ulcerative colitis flare. Fellows wrote a progress notes documenting the encounters. To add educational value, we gave the participants references about handoff communication. Four OSCE stations-handoff communication, telephone management, informed consent, and delivering bad news-were completed by fellows and observed by faculty. RESULTS: Eight faculty members and eight fellows from four GI training programs participated. All the fellows agreed that handoffs can be important learning opportunities and can be improved if they are structured, and that handoff skills can improve with practice. CONCLUSIONS: OSCEs can serve as practicums for assessing complex skill sets such as handoff communication and telephone management.
