Depression leads to incident vascular disease: evidence for the relevance to primary care

Gender-Stratified Prevalence of Psychiatric and Pain Diagnoses in a Primary Care Patient Sample with Fibromyalgia

OBJECTIVE

Comorbid psychiatric and pain-related conditions are common in patients with fibromyalgia. Most studies in this area have used data from patients in specialty care and may not represent the characteristics of fibromyalgia in primary care patients. We sought to fill gaps in the literature by determining if the association between psychiatric diagnoses, conditions associated with chronic pain, and fibromyalgia differed by gender in a primary care patient population.

DESIGN

Retrospective cohort.

SETTING AND SUBJECTS

Medical record data obtained from 38,976 patients, ≥18 years of age with a primary care encounter between July 1, 2008, to June 30, 2016.

METHODS

International Classification of Diseases-9 codes were used to define fibromyalgia, psychiatric diagnoses, and conditions associated with chronic pain. Unadjusted associations between patient demographics, comorbid conditions, and fibromyalgia were computed using binary logistic regression for the entire cohort and separately by gender.

RESULTS

Overall, 4.6% of the sample had a fibromyalgia diagnosis, of whom 76.1% were women. Comorbid conditions were more prevalent among patients with vs without fibromyalgia. Depression and arthritis were more strongly related to fibromyalgia among women (odds ratio [OR] = 2.80, 95% confidence interval [CI] = 2.50-3.13; and OR = 5.19, 95% CI = 4.62-5.84) compared with men (OR = 2.16, 95% CI = 1.71-2.71; and (OR = 3.91, 95% CI = 3.22-4.75). The relationship of fibromyalgia and other diagnoses did not significantly differ by gender.

CONCLUSIONS

Except for depression and arthritis, the burden of comorbid conditions in patients with fibromyalgia is similar in women and men treated in primary care. Fibromyalgia comorbidities in primary care are similar to those found in specialty care.

Sexual Dysfunction in Primary Care: An Exploratory Descriptive Analysis of Medical Record Diagnoses

BACKGROUND

The prevalence of sexual dysfunction (SDx) diagnoses in primary care settings is not well known, which is a concern because of the high prevalence of comorbid chronic health conditions in patients diagnosed with SDx.

AIM

To explore the relation of SDx diagnosis, chronic health conditions, and prescription medications commonly associated with SDx for men and women in primary care using medical records diagnoses.

METHODS

Exploratory descriptive analyses were used to interpret secondary data from a primary care patient database. The database included patient data from 3 family and internal medicine clinics in the St Louis metropolitan area from July 1, 2008 to June 30, 2015. Analysis included key demographic variables, chronic illness, and health conditions of hypertension, pain, prostate disorder, menopause, substance abuse, depression, anxiety, and associated medications. Analysis of the database yielded 30,627 adult patients (men: n = 12,097, mean age = 46.8 years, 65.6% white race; women: n = 18,530, mean age = 46.6 years, 59.2% white race) with significant comorbid associations between SDx and other chronic illness, health conditions, and medication prescription.

RESULTS

Depression, anxiety, pain, hypertension, diabetes, and psychotropic medication use were significantly associated with SDx for men and women. Examination of specific SDx diagnoses showed erectile dysfunction to be significantly associated with all tested variables for men. For women, pain-related SDx diagnoses were associated more with chronic illness, health conditions, and medication use than were psychosexual SDx diagnoses (eg, orgasm), except for menopause. Prevalence varied by sex, with a higher prevalence rate of any SDx for men (13.5%) than for women (1.0%), although sex comparisons were not part of the analytics.

CLINICAL TRANSLATION

This study suggests the diagnosis of SDx is closely associated with other common chronic illness and health conditions and could go underdiagnosed in women in primary care.

STRENGTHS AND LIMITATIONS

The cross-sectional nature of the study limits the ability to draw causal conclusions related to the nature of the associated conditions with SDx diagnoses. The generalizability of the findings also might be limited given the specific demographic or health makeup of the St Louis area where the study was conducted.

CONCLUSION

The high comorbidity of SDx with mental health, chronic pain and illnesses, and medication use adds to the growing evidence that sexual health and functioning are essential components of overall well-being and holistic care for men and women.

Chest Pain, Atherosclerotic Cardiovascular Disease Risk, and Cardiology Referral in Primary Care

Background: The atherosclerotic cardiovascular disease (ASCVD) 10-year risk estimate is recommended by cardiologists for determining risk of a cardiac event. However, the majority of patients presenting to primary care with chest pain have noncardiac etiologies. Therefore, we determined if high versus low ASCVD risk was associated with primary care physicians’ referral to cardiology in patients with and without chest pain. Methods: Deidentified electronic health record (EHR) data was obtained from 5795 patients treated in academic primary care clinics from 2008 to 2015. Referral to cardiology was defined by an EHR code, chest pain was defined by ICD-9-CM code (786.5) and ASCVD was modeled as high versus low risk. Separate logistic regression models were computed to estimate the association between chest pain and referral to cardiology, ASCVD risk and referral, and both chest pain and ASCVD risk and referral with adjustment for potential confounding factors. Results: More patients with (n = 95, 7.8%) versus without (n = 75, 2.0%) chest pain were referred to cardiology (P < .0001). Separate unadjusted models revealed chest pain and high versus low ASCVD risk were significantly associated with referral (odds ratio [OR] = 4.20; 95% confidence interval [CI] 3.07-5.73 and OR = 1.41; 95% CI 1.04-1.91, respectively). After adjusting for ASCVD risk and confounders, chest pain but not high ASCVD risk remained significantly associated with referral (OR = 1.75; 95% CI 1.24-2.47 and OR = 1.15; 95% CI 0.72-1.82, respectively). Conclusions: In primary care patients presenting with chest pain, ASCVD risk scores are not associated with referral to cardiology. Overall, less than 8% of patients with chest pain were referred. While there is no evidence to indicate excessive referral to cardiology, we posit that implementing ASCVD risk tools in decision aids could contribute to referring those most in need of cardiology care.

Association between race and receipt of counselling or medication for smoking cessation in primary care

BACKGROUND

Previous evidence of race disparities in smoking cessation treatment has been limited to mostly survey studies which increase the potential for recall bias. We examined if African American versus white patients in primary care are less likely to receive any treatment or if race disparities are specific to the type of treatment offered using data pulled from a large electronic health record system.

METHODS

Medical record data from 3510 white and 2707 African American patients were available from primary care encounters between 2008 and 2015 and was used to define smoking status, cessation treatments (counselling and medication), and covariates. The association between race and type of smoking cessation treatment offered was measured by logistic regression models before and after adjusting for covariates.

RESULTS

Smoking cessation counselling was offered to 9.3% of African American and 7.8% of white patients, and a prescription for smoking cessation medication was offered to 12.3% of African American and 16.4% of white patients. After adjusting for covariates in logistic regression models, whites were significantly less likely than African American patients to receive smoking cessation counselling [odds ratio (OR) = 0.81; 95% confidence interval (CI) = 0.65-0.99] and were significantly more likely to receive a prescription for a smoking cessation medication (OR = 1.23; 95% CI = 1.03-1.47).

CONCLUSIONS

Less than 20% of smokers received any type of therapy to assist in smoking cessation. We observed a race disparity in type of smoking cessation therapy provided to white and African American primary care patients. Further research is needed to increase treatment rates and eliminate disparities.

Fast GFR decline and progression to CKD among primary care patients with preserved GFR

BACKGROUND

Fast glomerular filtration rate (GFR) decline is associated with adverse outcomes, but the associated risk factors among patients without chronic kidney disease (CKD) are not well defined.

METHODS

From a primary care registry of 37,796, we identified 2219 (6%) adults with at least three estimated (e)GFR values and a baseline eGFR between 60 and 119 ml/min/1.73 m² during an observation period of 8 years. We defined fast GFR decline as > 5 ml/min/1.73 m² per year. The outcome measure was incident CKD (eGFR < 60 ml/min/1.73 m²). Clinical and demographic characteristics were compared using Chi-square and independent-samples t tests.

RESULTS

Older age, African-American race, unmarried status, hypertension and type 2 diabetes were more common in both fast decliners and those who developed incident CKD (p < 0.0001 to < 0.05). Lower neighborhood socioeconomic status, current smoking and baseline eGFR 90-119 ml/min/1.73 m² were associated with fast decline (p < 0.01), while baseline eGFR 60-74 ml/min/1.73 m² with incident CKD (p < 0.05). In multivariate regression models, among fast decliners with mildly reduced baseline eGFR (60-89 ml/min/1.73 m²), older age was significantly associated with incident CKD [odds ratio (OR) 1.04; 95% CI 1.01-1.08], and among those with normal baseline eGFR (≥ 90-119 ml/min/1.73 m²), type 2 diabetes was significantly associated with incident CKD (OR 3.83; 95% CI 1.35-10.89).

CONCLUSIONS

Among primary care patients without CKD, GFR is checked infrequently. We have identified patients at high risk of progressive CKD, in whom we suggest a closer monitoring of renal function.

Rate of renal function decline, race and referral to nephrology in a large cohort of primary care patients

INTRODUCTION

Late nephrology referral is associated with adverse outcomes especially among minorities. Research on the association of the rate of chronic kidney disease (CKD) progression with nephrology referral in white versus black patients is lacking.

OBJECTIVES

Compute the odds of nephrology referral in primary care and their associations with race and the rate of CKD progression.

METHODS

Electronic health record data were obtained from 2170 patients in primary care clinics in the Saint Louis metropolitan area with at least two estimated glomerular filtration rate (eGFR) values over a 7-year observation period. Fast CKD progression was defined as a decline in eGFR of ≥5 ml/min/1.73 m2/year. Logistic regression models were computed to measure the associations between eGFR progression, race and nephrology referral before and after adjusting for potential confounding factors.

RESULTS

Nephrology referrals were significantly more prevalent among those with fast compared to slow progression (5.6 versus 2.0%, P < 0.0001), however, a majority of fast progressors were not referred. Fast CKD progression and black race were associated with increased odds of nephrology referral (OR = 2.74; 95% CI: 1.60-4.72 and OR = 2.42; 95% CI: 1.28-4.56, respectively). The interaction of race and eGFR progression in nephrology referral was found to be non-significant.

CONCLUSION

Nephrology referrals are more common in fast CKD progression, but referrals are underutilized. Nephrology referral is more common among blacks but its' association with rate of decline does not differ by race. Further studies are required to investigate the benefit of early referral of patients at risk of fast CKD progression.
