Clinical Decision Support for Providers: cardiovascular diseases l l Reference l Magid DJ, et. al, A multimodal blood pressure control intervention in 3 healthcare systems. Am J Manag Care. 2011 Apr; 17(4): e 96 -103 Source l Institute for Health Research, Kaiser Permanente Colorado, Denver. Aim l To determine if a multimodal intervention composed of patient education, home blood pressure (BP) monitoring, BP measurement reporting to an interactive voice response (IVR) phone system, and clinical pharmacist follow-up improves BP control compared with usual care. Methods l RCT conducted at 3 healthcare systems in Denver, Colorado, including a large health maintenance organization, a Veterans Affairs medical center, and a county hospital. l Prospective study with patient enrollment, medication consultation and adjustment, remote BP monitoring, and follow-up at 6 months.

Am J Manag Care. 2011 Apr; 17(4): e 96 -103. . Methods, cont’d l At each site, patients with uncontrolled BP were randomized to the multimodal intervention vs usual care for 6 months, with the primary end point of BP reduction. Results l 338 patients randomized, 283 (84%) completed the study, including 138 intervention patients and 145 usual care patients. l BP was higher in the intervention group vs the usual care group (150. 5/89. 4 vs 143. 8/85. 3 mm Hg). l At 6 months, BPs were similar in the intervention group vs the usual care group (137. 4 vs 136. 7 mm Hg, P =. 85 for systolic; 82. 9 vs 81. 1 mm Hg, P =. 14 for diastolic).

Am J Manag Care. 2011 Apr; 17(4): e 96 -103. Results, cont’d l BP reductions were greater in the intervention group vs the usual care group (− 13. 1 vs − 7. 1 mm Hg, P =. 006 for systolic; − 6. 5 vs − 4. 2 mm Hg, P =. 07 for diastolic). l Adherence to medications was similar between the 2 groups, but intervention patients had a greater increase in medication regimen intensity. Conclusions l A multimodal intervention of patient education, home BP monitoring, BP measurement reporting to an IVR system, and clinical pharmacist follow-up achieved greater reductions in BP compared with usual care.

Methods, cont’d l SQLIs were scored for level of severity or distress. l One on-treatment clinic visit was audio recorded for each participant and then scored for discussion of each SQLI. l Authors hypothesized that problematic SQLIs would be discussed more often when the intervention was delivered to the clinicians. Results l The likelihood of SQLIs being discussed differed by randomized group and depended on whether an SQLI was first reported as problematic (P =. 032). l Clinic visits were similar with regard to duration between groups, and clinicians reported the summary as useful

Aim l To compare achievement of and improvement in quality standards for diabetes at practices using EHRs with CDSS with those at practices using paper records. Methods l All practices, including many safety-net primary care practices, belonged to a regional quality collaborative and publicly reported performance. l Authors used generalized estimating equations to calculate the percentage-point difference between EHR-based and paper-based practices with respect to achievement of composite standards for diabetes care (including four component standards) and outcomes (five standards), after adjusting for covariates and accounting for clustering.

Results l From July 2009 through June 2010, data were reported for 27, 207 adults with diabetes seen at 46 practices; safety-net practices accounted for 38% of patients. l After adjustment for covariates, achievement of composite standards for diabetes care was 35. 1 percentage points higher at EHR sites than at paper-based sites (P<0. 001), and achievement of composite standards for outcomes was 15. 2 percentage points higher (P=0. 005).

Methods, cont’d l Primary outcomes were the incidence of medication errors; potential adverse drug events, defined as errors with potential for harm; and rate of prescribing errors by error type and by prescribing system. Results l Of 3850 prescriptions, 452 (11. 7%) contained 466 total errors, of which 163 (35. 0%) were considered potential adverse drug events. l Error rates varied by computerized prescribing system, from 5. 1% to 37. 5%. The most common error was omitted information (60. 7% of all errors). l Results consistent with literature on manual handwritten prescription error rates. The number, type, and severity of errors varied by computerized prescribing system, suggesting that some systems may be better at preventing errors than others.

(Last work of Marco Ramoni) l Kamper P, et. al, Proteomic analysis identifies galectin-1 as a predictive biomarker for relapsed/refractory disease in classical Hodgkin lymphoma. Blood. 2011 Jun 16; 117(24): 663849. Epub 2011 Apr 19. Key findings: Proteomic analysis of 14 Hodgkins lymphoma found a common protein biomarker that predicts treatment response and survival
Bioinformatics: Human Health & Disease – cancer l References l Stein RA, et. al, Epigenetics--the link between infectious diseases and cancer. JAMA. 2011 Apr 13; 305(14): 1484 -5. A good review of the relationship of the microbiome and cancer in humans.
Bioinformatics: Human Health & Disease – CNS l References l Gilman SR et. al, Rare de novo variants associated wih autism implicate a large functional network of genes involved in formation and function of synapses. Neuron. 2011 Jun 9; 70(5): 898 -907. [Columbia Univ. ] Key findings: Used analysis of rare genetic variants to show autism linked to synapse development, and explain why autism is more common in males than females. l Föcking M, et. al, Common proteomic changes in the hippocampus in schizophrenia and bipolar disorder and particular evidence for involvement of cornu ammonis regions 2 and 3. Arch Gen Psychiatry. 2011 May; 68(5): 477 -88. [Royal College of Surgeons, Dublin Ireland] Key findings: Used proteomics to find distinctive abnormal proteins in the hippocampus in schizophrenia and bipolar disorder.
The Practice of Bioinformatics l Reference l Altman RB, et. al, Pharmacogenomics: "noninferiority" is sufficient for initial implementation. Clin Pharmacol Ther. 2011 Mar; 89(3): 348 -50. [Stanford Univ. ] Key findings: because of the combinatorics of rare variants predict that conclusive evidence of gene-drug effects will often not be found with the certainty levels used in clinical trials, standard for using pharmacogenetic data should be whether it is no worse than standard prescribing.
