Electronically measured adherence to immunosuppressive medications and kidney function after deceased donor kidney transplantation.

BACKGROUND: Non-adherence with immunosuppressive medications can result in allograft rejection and eventually allograft loss. METHODS: In a racially diverse population, we utilized microelectronic cap monitors to determine the association of adherence with a single immunosuppressive medication and kidney allograft outcomes post-transplantation. This prospective cohort study enrolled 243 patients from eight transplant centers to provide adherence and kidney allograft outcomes data. To determine the association of adherence with change in estimated glomerular filtration rate (eGFR), we fit mixed effects models with the outcome being change in eGFR over time. We also fit Cox proportional hazards models to determine the association of adherence with time to persistent 25% and 50% decline in eGFR. RESULTS: The distribution of adherence post-transplant was as follows: 164 (68%), 49 (20%), and 30 (12%) had >85-100%, 50-85%, and <50% adherence, respectively. Seventy-nine (33%) and 36 (15%) of the subjects experienced a persistent 25% decline in eGFR or allograft loss and 50% decline in eGFR or allograft loss during follow-up. Adherence was not associated with acute rejection or 25% decline or 50% decline in eGFR. In the adjusted and unadjusted model, adherence and black race were not associated with change in eGFR over time. CONCLUSIONS: Non-adherence with a single immunosuppressive medication was not associated with kidney allograft outcomes.

Comparison of dobutamine stress echocardiography, dobutamine SPECT, and adenosine SPECT myocardial perfusion imaging in patients with end-stage renal disease.

OBJECTIVES: We sought to assess and compare the diagnostic accuracy and prognostic value of dobutamine stress echocardiography (DSE), dobutamine SPECT, and adenosine SPECT myocardial perfusion imaging (MPI) in patients with end-stage renal disease (ESRD). BACKGROUND: The optimal stress imaging modality for patients with ESRD has not yet been determined. METHODS: Forty-nine patients with ESRD underwent DSE, dobutamine SPECT MPI, and adenosine SPECT MPI. The primary endpoint of the trial was concordance between stress tests with respect to the presence or absence of ischemia. RESULTS: Agreement on the presence or absence of ischemia between adenosine SPECT MPI and DSE was 69% (kappa = .25, P = NS). Agreement on the presence or absence of ischemia between adenosine and dobutamine SPECT MPI was 77% (kappa = .37, P = <.009). Summed stress scores for adenosine and dobutamine SPECT MPI studies were highly correlated (r = .9, P = <.0001). DSE and SPECT MPI results provided incremental prognostic information when added to clinical variables. CONCLUSIONS: There is moderate concordance between DSE and adenosine SPECT MPI in ESRD patients referred for stress testing. Interobserver agreement was higher for SPECT MPI compared to DSE. Based on these observations, the optimal approach for diagnosing severe coronary artery disease and assessing risk in patients with ESRD has yet to be determined, but appears to warrant further investigation.

Unsuspected or unacknowledged depressive symptoms in young adult emergency department patients.

OBJECTIVES: The objective was to determine the frequency of unsuspected or unacknowledged depressive symptoms among young adult emergency department (ED) patients. METHODS: The Beck Depression Inventory-II (BDI-II) and a demographic/lifestyle questionnaire were administered to a cross-section of medically stable, English-speaking young adult ED patients (aged 18-23 years) with nonpsychiatric chief complaints. The frequency of moderate to severe depressive symptoms was determined. Group results were analyzed with descriptive statistics; multivariate analysis assessed for patient characteristics associated with depressive symptoms. RESULTS: A total of 2,898 patients were screened; 2,255 were eligible for enrollment, and 1,264 enrolled (56%; 64% female, 42% African American; mean age = 21 [+/-1.7] years). Twenty-nine percent had BDI-II scores consistent with moderate to severe depressive symptoms. Patient characteristics associated with depressive symptoms included knowledge of someone who had intentionally hurt him- or herself (odds ratio [OR] = 2) or died a violent nonaccidental death (OR = 1.4), low personal income (OR = 1.8), chronic health issues (OR = 1.7), cigarette smoking (OR = 1.6), and African American race (OR = 1.5). Those who attended school (OR = 0.5), engaged in frequent social activities (OR = 0.5), or drove a car (OR = 0.7) were less likely to have depressive symptoms. Patients lacked insight into their depressive symptoms. CONCLUSIONS: There is a high prevalence of depressive symptoms in young adult ED patients. Young adults often do not recognize, or are reluctant to acknowledge, depressive symptoms. Specific patient characteristics may be useful in deciding which young adults should undergo ED screening for depression.

Occult depressive symptoms in adolescent emergency department patients.

OBJECTIVES: To estimate the frequency of occult depressive symptoms in adolescent emergency department (ED) patients (aged 13-17 years) and to determine patient characteristics associated with depressive symptoms. DESIGN: A cross-sectional study of adolescent ED patients. SETTING: The pediatric ED of Hennepin County Medical Center in Minneapolis, Minnesota, and the EDs of the Children's Hospitals and Clinics of Minnesota. PATIENTS: Medically stable adolescent ED patients with nonpsychiatric concerns. INTERVENTIONS: Patients completed the Beck Depression Inventory II and answered questions about their attitudes, activities, and lifestyle choices. Guardians were asked about family demographics, living situations, and other patient characteristics. MAIN OUTCOME MEASURES: The frequency of moderate and severe depressive symptoms as measured by the Beck Depression Inventory II. Group results were analyzed with descriptive statistics; patient characteristics associated with depressive symptoms were determined by multivariate analysis. RESULTS: A total of 967 patients were enrolled. According to the Beck Depression Inventory II, 20% (197 patients) had moderate to severe depressive symptoms. Of these, 58% recognized their depressive symptoms and 50% were recognized by their guardians as having depressive symptoms. When compared with nondepressed patients, adolescents with depressive symptoms more often were female, were not involved in organized social activities, knew someone who intentionally hurt himself or herself or died a violent death, were currently involved in a sexual relationship, or used street drugs. Race, family income, family stability, and witnessing violence were not associated with a positive depression screen result. CONCLUSIONS: Depressive symptoms occur frequently among adolescents and are often unrecognized. Efforts to increase awareness of depression among ED physicians, adolescents, and parents of adolescents may be beneficial.

Predictors of outcomes after biliary and pancreatic sphincterotomy for sphincter of oddi dysfunction.

BACKGROUND: There are few data on combined pancreatic and biliary sphincterotomy for sphincter of Oddi dysfunction (SOD), especially regarding clinical features that might predict outcomes. We sought to examine the relative importance of various clinical features and the presence or absence of objective biliary abnormalities in determining responses to endoscopic therapy. METHODS: A cohort of consecutive patients with suspected SOD was treated with biliary sphincterotomy, with additional pancreatic sphincterotomy at initial or subsequent endoscopic retrograde cholangiopancreatography if there was abnormal pancreatic manometry in conjunction with pain refractory to biliary sphincterotomy, continuous pain, or a history of amylase elevation. Repeat intervention was offered until response was achieved or complete ablation of all treated sphincters was achieved. Response was assessed by patients using a 5-point Likert scale, and multivariate logistic regression analysis used to identify predictors of response. RESULTS: Of 121 patients, 112 (92%) were female, 105 (87%) postcholecystectomy, and by modified Milwaukee biliary classification 18 (15%) were type I, 53 (44%) type II, and 50 (41%) type III. All patients underwent biliary sphincterotomy and 49 (40%) pancreatic sphincterotomy. Good or excellent response at final follow-up was reported by 83 (69%) of 121 patients, including 37 (61%) of 61 patients requiring repeated intervention. Response was not significantly different between biliary types I, II, and III. Patient characteristics (with adjusted odds ratios) that were significant predictors of poor response were normal pancreatic manometry (4.6), delayed gastric emptying (6.0), daily opioid use (4.0), and age <40 (2.7). Abnormal liver function tests or dilated bile duct were not significant. CONCLUSIONS: For the treatment of SOD incorporating pancreatic and biliary sphincterotomy, patient characteristics and pancreatic sphincter manometry may be more important predictors of outcome than the traditional classification based on liver chemistries and bile duct dilation.

Variability in glycosylated hemoglobin values in diabetic patients living in long-term care facilities.

OBJECTIVES: The objectives of this study were to determine the prevalence of diabetes and mean A1C of patients in long-term care facilities (LTCFs); to determine differences in A1C values based on patient characteristics; and to examine the self-reported practices of providers regarding diabetes management goals. DESIGN: Twelve-month retrospective review of patient charts; survey of physicians and nurse practitioners providing care to these patients. SETTING: Nursing facility practice of an urban teaching hospital. PARTICIPANTS: Participants included 168 diabetic patients living in 20 nursing facilities and 18 physician and nurse practitioners in one practice providing care to these patients. RESULTS: The prevalence of diabetes was 21.6% (168 of 778 patients). Mean A1C was 7.1% +/- 1.2%for 135 patients who had AIC values measured during the study interval. A1C varied by age, with patients younger than 65 having higher A1C values than patients older than 65. Higher A1C values were associated with insulin use, frequent glucose monitoring, and attending a diabetes clinic. Although a survey of providers identified modifying A1C target ranges for LTCF compared with ambulatory patients, they did not reach consensus on the actual target A1C. No association between provider perception of either patient health status or patient life expectancy and A1C values was found. CONCLUSIONS: Relatively low A1C values were obtainable in LTCF patients without diabetes specialty clinic use. Providers identified modifying target A1C values for LTCF patients, but achieved relatively low A1C values and did not agree on a target A1C value for LTCF patients.
