Referral Patterns for Primary Prophylaxis Implantable Cardioverter Defibrillator Therapy for an Urban US Population

Self-referrals versus physician referrals: What new patient visit yields an actual surgical case?

OBJECTIVE Spine surgeons in the United States continue to be overwhelmed by an aging population, and patients are waiting weeks to months for appointments. With a finite number of clinic visits per surgeon, analysis of referral sources needs to be explored. In this study, the authors evaluated patient referrals and their yield for surgical volume at a tertiary care center. METHODS This is a retrospective study of new patient visits by the spine surgery group at the Cleveland Clinic Center for Spine Health from 2011 to 2016. Data on all new or consultation visits for 5 identified spinal surgeons at the Center for Spine Health were collected. Patients with an identifiable referral source and who were at least 18 years of age at initial visit were included in this study. Univariate analysis was used to identify demographic differences among referral groups, and then multivariate analysis was used to evaluate those referral groups as significant predictors of surgical yield. RESULTS After adjusting for demographic differences across all referrals, multivariate analysis identified physician referrals as more likely (OR 1.48, 95% CI 1.04-2.10, p = 0.0293) to yield a surgical case than self-referrals. General practitioner referrals (OR 0.5616, 95% CI 0.3809-0.8278, p = 0.0036) were identified as less likely to yield surgical cases than referrals from interventionalists (OR 1.5296, p = 0.058) or neurologists (OR 1.7498, 95% CI 1.0057-3.0446, p = 0.0477). Additionally, 2 demographic factors, including distance from home and age, were identified as predictors of surgery. Local patients (OR 1.21, 95% CI 1.13-1.29, p = 0.018) and those 65 years of age or older (OR 0.80, 95% CI 0.72-0.87, p = 0.0023) were both more likely to need surgery after establishing care with a spine surgeon. CONCLUSIONS In conclusion, referrals from general practitioners and self-referrals are important areas where focused triaging may be necessary. Further research into midlevel providers and nonsurgical spine provider's role in these referrals for spine pathology is needed. Patients from outside of the state or younger than 65 years could benefit from pre-visit screening as well to optimize a surgeon's clinic time use and streamline patient care.

[We implant too many ICD - contra]

Based on prospective population-based cohort studies from the Netherlands approximately 120,000 sudden cardiac deaths (SCD) have to be assumed in 2014 in Germany for persons older than 55 years of age without an implantable cardioverter defibrillator (ICD). In contrast in 2014 only 30,000 ICD were implanted in Germany. Due to the fact that victims of SCD are difficult to predict many more implantations are actually necessary because only approximately one third of the patients use their ICD during battery running time. Also according to the largest ICD study on ischemic cardiomyopathy at least six patients must be treated with an ICD to save one life after 8 years. Guidelines for ICD implantation are based on 12 randomized studies with more than 9000 patients. In 2014 in Germany 94 % of ICD implantations were carried out in accordance with the guidelines. The most important studies for primary prophylaxis of SCD (MADIT 2 and SCD-HeFT) finished recruitment of patients in 2001 but propensity score-matched ICD patients from a large national data base showed identical survival curves in 2005 and 2006. New ICD developments in recent years, such as suppression of inappropriate ICD therapy by improved programming, cardiac resynchronization, and telemonitoring showed promise for current ICD patients of improved survival in comparison to the original randomized patients from the studies, which led to the indications in the guidelines.
