Does Clinical Decision Support Increase Appropriate Medication Prescribing for Cardiovascular Risk Reduction?

PURPOSE: To assess the impact of a clinical decision support (CDS) system's recommendations on prescribing patterns targeting cardiovascular disease (CVD) when the recommendations are prioritized in order from greatest to least benefit toward overall CVD risk reduction. METHODS: Secondary analysis of trial data from September 20, 2018, to March 15, 2020, where 70 community health center clinics were cluster-randomized to the CDS intervention (42 clinics; 8 organizations) or control group (28 clinics; 7 organizations). Included patients were medication-naïve and aged 40 to 75 years with ≥1 uncontrolled cardiovascular disease risk factor, with known diabetes or cardiovascular disease, or ≥10% 10-year reversible CVD risk. RESULTS: Among eligible encounters with 29,771 patients, the probability of prescribing a medication targeting hypertension was greater at intervention clinic encounters when CDS was used (34.9% [95% CI, 31.5 to 38.3]) versus dismissed (29.6% [95% CI, 26.7 to 32.6]; P < .001), but not when compared with control clinic encounters (34.9% [95% CI, 31.1 to 38.7]; P = .998). Prescribing for dyslipidemia was significantly higher at intervention encounters where the CDS system was used (11.3% [95% CI, 9.3 to 13.3]) compared with dismissed (7.7% [95% CI, 6.1 to 9.3]; P = .003) and to control encounters (8.7% [95% CI, 7.0 to 10.4]; P = .044); smoking cessation medication showed a similar pattern. Except for dyslipidemia, prescribing rates increased according to their prioritization. CONCLUSIONS: Use of this CDS system was associated with significantly higher prescribing targeting most cardiovascular risk factors. These results highlight how displaying prioritized actions to reduce reversible CVD risk could improve risk management.

Adoption of shared decision-making and clinical decision support for reducing cardiovascular disease risk in community health centers.

Objective: Electronic health record (EHR)-based shared decision-making (SDM) and clinical decision support (CDS) systems can improve cardiovascular disease (CVD) care quality and risk factor management. Use of the CV Wizard system showed a beneficial effect on high-risk community health center (CHC) patients' CVD risk within an effectiveness trial, but system adoption was low overall. We assessed which multi-level characteristics were associated with system use. Materials and Methods: Analyses included 80 195 encounters with 17 931 patients with high CVD risk and/or uncontrolled risk factors at 42 clinics in September 2018-March 2020. Data came from the CV Wizard repository and EHR data, and a survey of 44 clinic providers. Adjusted, mixed-effects multivariate Poisson regression analyses assessed factors associated with system use. We included clinic- and provider-level clustering as random effects to account for nested data. Results: Likelihood of system use was significantly higher in encounters with patients with higher CVD risk and at longer encounters, and lower when providers were >10 minutes behind schedule, among other factors. Survey participants reported generally high satisfaction with the system but were less likely to use it when there were time constraints or when rooming staff did not print the system output for the provider. Discussion: CHC providers prioritize using this system for patients with the greatest CVD risk, when time permits, and when rooming staff make the information readily available. CHCs' financial constraints create substantial challenges to addressing barriers to improved system use, with health equity implications. Conclusion: Research is needed on improving SDM and CDS adoption in CHCs. Trial Registration: ClinicalTrials.gov, NCT03001713, https://clinicaltrials.gov/.

Treatment of Unfavorable Bleeding Patterns in Contraceptive Implant Users: A Randomized Controlled Trial.

OBJECTIVE: To evaluate whether a short course of tamoxifen decreases bothersome bleeding in etonogestrel contraceptive implant users. METHODS: In a 90-day, double-blind randomized control trial, we enrolled etonogestrel implant users with frequent or prolonged bleeding or spotting. A sample size of 40 per group (N=80) was planned to compare 10 mg tamoxifen or placebo twice daily for 7 days after 3 consecutive days of bleeding or spotting no more than once per 30 days (maximum three treatments). Participants then entered a 90-day open-label study where all received tamoxifen if needed every 30 days (maximum three treatments). Participants used text messages to record daily bleeding patterns. Our primary outcome was the total number of consecutive amenorrhea days after the first treatment. Secondary outcomes included time to bleeding or spotting cessation and restart after first treatment, overall bleeding patterns, and satisfaction. RESULTS: From January 2017 to November 2018, 112 women enrolled in the study; 88 (79%) completed 90 days, and 79 (71%) completed 180 days. Participant characteristics did not differ between groups; mean age 24, majority identified as white not Hispanic with at least some college education. After the first treatment, the tamoxifen group reported an average of 9.8 (95% CI 4.6-15.0) more consecutive days of amenorrhea and more total days of no bleeding (amenorrhea or spotting) in the first 90 days (median 73.5 [range 24-89] vs 68 [range 11-81], P=.001). The placebo group showed a similar treatment benefit after first active use of tamoxifen in the open-label phase. At the end of the randomized study (first 90 days), women who received tamoxifen reported higher satisfaction (median 62 mm [range 16-100]) than those treated with placebo (46 mm [range 0-100]; P=.023). CONCLUSION: A short course of tamoxifen reduces problematic bleeding and improves satisfaction in users of etonogestrel implants. CLINICAL TRIAL REGISTRATION: ClinicalTrials.gov, NCT02903121.
