Background While several studies have suggested that anesthesia and surgical care episodes provide an opportunity to improve the diagnosis and treatment of hypertension, few studies have implemented and tested pragmatic care coordination efforts for this population. The present study aimed to examine the effects of same-day primary care referral vs. usual care on outpatient hypertension treatment among patients with elevated preoperative clinic blood pressure (BP). Methodology With institutional review board approval of the project as a quality improvement (QI) initiative not requiring consent, we conducted a prospective QI project comparing same-day preoperative primary care referral vs. usual care within comparable cohorts of US Veterans presenting to a preoperative evaluation clinic with elevated BP for whom treatment assignment was based on prior primary care clinic affiliation. Outpatient BP, antihypertensive medications, and antihypertensive dosages at the initial visit and for one year after the initial preoperative clinic visit were followed in the electronic health record. Results Between June 1, 2018, and June 1, 2019, one of the two on-site primary care groups (Firm A) at our facility agreed to accommodate same-day BP referrals. Patients in the second primary care group received standard preoperative care (Firm B). Charts for the pseudo-randomized cohort of Firm A and B patients were compared after 12 months to assess for changes in BP and hypertension treatment. Firm A and B patients were similar in demographics. Overall, 68 (91%) Firm A patients were correctly referred for primary care appointments. Moreover, 28 of 68 (41.2%) patients adhered to the same-day referral recommendation, with the remainder declining to attend the primary care visit. BPs were similar between Firm A and Firm B groups at 3, 6, 9, and 12 months post-intervention. Firm A adherent patients (i.e., those attending the referral) received hypertension treatment intensification sooner than Firm A non-adherent and Firm B patients (median (interquartile range) days to intensification = 21 (0.5-103.5) vs. 154 (45.5-239) and 170 (48-220), respectively; p = 0.038 and p = 0.048, respectively). Conclusions Our protocol achieved a high degree of same-day primary care referral (91%) in hypertensive patients presenting at the preoperative clinic. Although this limited study did not demonstrate improved BP control in patients who received same-day primary care, this group did show increased rates of rapid treatment intensification which may infer improved long-term health outcomes. Further work examining logistical barriers to patients attending same-day referrals is warranted.
