Incidence and Prevalence of Cough in a Rural Health System: A 20-Year Study.

OBJECTIVE: Understanding the cough population is critical to addressing clinical needs and gaps in best practice. We sought to characterize and stratify cough patients with the hypothesis that there are opportunities to improve access to care in our health system and characterize the population. METHODS: Following institutional review board exempt status, a retrospective electronic record review was performed on all patients coded with ICD-9 786.2 or ICD-10 is R05 from January 1, 2001 through December 31, 2020 at our health system. Inclusion criteria were one or more visits for cough. The subgroup with more than one visit in each of 2 years was classified as multiple encounters. Patients were characterized by sex, age at first cough encounter, number of cough encounters, smoking status, and insurance status. Results were stratified by year, calculating frequencies, and percentages. RESULTS: There were 302,284 unique patients diagnosed with cough, among 1,764,387 patients seen in our health system, representing an average incidence of 3.0% (2.7%-3.7%) and prevalence of 4.9% (3.1%-5.6%). New single encounter cough patients totaled 179,963, and new multiple encounter cough patients totaled 122,321. Of the 39,828,073 total encounters, there were 469,802 for new or existing cough (1.17%-1.73% annually). The age at initial presentation demonstrated 36.5% seen <10 years old, with an even distribution over the remaining decades of life. The majority were seen for cough once, but 23.8% of group two patients had two or more visits for cough in a year. CONCLUSION: We demonstrate a lower-than-expected incidence and prevalence of cough in our health population, suggesting challenges with access to care when compared to 10% prevalence and 3% of encounters previously documented in the literature. The study also provides a platform to explore the importance of pediatric cough, as well as population health and the longitudinal journey of cough patients in underserved areas.

Characterizing primary care for patients with major depressive disorder using electronic health records of a US-based healthcare provider.

BACKGROUND: Major depressive disorder (MDD) is predominantly managed in primary care. However, primary care providers (PCPs) may not consistently follow evidence-based treatment algorithms, leading to variable patient management that can impact outcomes. METHODS: We retrospectively analyzed adult patients with MDD seen at Geisinger, an integrated health system. Utilizing electronic health record (EHR) data, we classified patients as having MDD based on International Classification of Disease (ICD)-9/10 codes or a Patient Health Questionnaire (PHQ)-9 score ≥5. Outcomes assessed included time to first visit with a PCP or behavioral health specialist following diagnosis, antidepressant medication switching, persistence, healthcare resource utilization (HRU), and treatment costs. RESULTS: Among the 38,321 patients with MDD managed in primary care in this study, significant delays between diagnosis with antidepressant prescribing and follow-up PCP visits were observed. There was also considerable variation in care following diagnosis. Overall, 34.9% of patients with an ICD-9/10 diagnosis of MDD and 41.3% with a PHQ-9 score ≥15 switched antidepressants. An ICD-9/10 diagnosis, but not moderately severe to severe depression, was associated with higher costs and HRU. More than 75% of patients with MDD discontinued antidepressant medication within 6 months. LIMITATIONS: The study population was comparable with other real-world studies of MDD, but study limitations include its retrospective nature and reliance on the accuracy of EHRs. CONCLUSIONS: Management of patients with MDD in a primary care setting is variable. Addressing these gaps will have important implications for ensuring optimal patient management, which may reduce HRU and treatment medication costs, and improve treatment persistence.

Agreement between heart failure patients and providers in assessing New York Heart Association functional class.

BACKGROUND: Uncertainty persists regarding whether patient assessment of New York Heart Association (NYHA) functional classification should be preferred over provider assessment among patients with heart failure (HF). OBJECTIVES: To compare patient against provider NYHA assessments, and both to distance walked on a 6-minute walk test (6MWT) among patients with HF. METHODS: In this prospective study, we enrolled 101 HF patients who self-assessed NYHA classification. Health care providers who were blinded to patient ratings of NYHA also rated NYHA. Patients completed a 6MWT according to a standardized protocol. We used Spearman coefficients (rs) to evaluate the correlations between variables. RESULTS: Patient- and provider-determined NYHA class were poorly correlated, but the relationship was statistically significant (rs = 0.40, p < 0.001). Patients consistently reported better NYHA class (class I: 72% vs 15%) than providers. Provider-determined NYHA had a stronger correlation with 6MWT distance (rs = -0.36, p < 0.001 vs. rs = -0.22, p = 0.03). Providers assigned a worse class to older patients who had comorbidity; patients with dyspnea and longer HF duration assigned themselves a worse class. CONCLUSION: Patients and providers exhibited poor agreement in NYHA assignment.

Impact of Switching From Prasugrel to Clopidogrel Shortly After a Percutaneous Coronary Intervention Without a Loading Dose of Clopidogrel.

OBJECTIVE: To determine the safety and efficacy of administering prasugrel at the time of percutaneous coronary intervention (PCI), and switching to clopidogrel, without reloading. BACKGROUND: Prasugrel has faster onset of action and appears to be of greater benefit than clopidogrel, particularly early after PCI. However, long-term prasugrel increases bleeding. Many physicians at Geisinger Medical Center (GMC) administer prasugrel before PCI and switch to clopidogrel afterward. The safety and efficacy of this strategy has not been studied. METHODS: We performed a retrospective study using electronic medical records and identified patients at GMC who underwent PCI between February 1, 2009 and January 31, 2012 and received a loading dose of prasugrel with a subsequent switch to clopidogrel, without reloading. The primary endpoint was major adverse cardiovascular event (MACE), defined as death, myocardial infarction (MI), stroke, or stent thrombosis, 7 days after the first dose of clopidogrel. Secondary endpoints included MACE at 30 days, individual MACE components at 7 and 30 days post procedure, and bleeding as defined by the Bleeding Academic Research Consortium (BARC) at 1 day and 30 days. RESULTS: A total of 151 patients met inclusion criteria. One patient suffered a MACE on day 7 (0.7%; 95% confidence interval, 0.03%-3.33%). One patient had an MI between 8-30 days. Two patients had BARC bleeding (type 2 and type 3b) 30 days post PCI. CONCLUSIONS: In this small, retrospective analysis, the results of loading patients with prasugrel for PCI and switching them to clopidogrel without a loading dose appear to be encouraging.
