Technology enabled home-based cardiac rehabilitation among women with cardiovascular disease: A longitudinal cohort study.

Technology-enabled home-based cardiac rehabilitation (HBCR) is an emerging alternative to traditional center-based cardiac rehabilitation (CBCR), but little is known about outcomes in women. We analyzed 753 diverse and medically complex women who participated in HBCR and CBCR within an integrated health system and found both groups had similar clinical outcomes. Results suggest HBCR is a viable alternative to CBCR among women, including women with multiple comorbidities.

Comparison of Home-Based vs Center-Based Cardiac Rehabilitation in Hospitalization, Medication Adherence, and Risk Factor Control Among Patients With Cardiovascular Disease.

Importance: Prior studies have suggested that participation in home-based cardiac rehabilitation (HBCR) vs center-based cardiac rehabilitation (CBCR) results in similar clinical outcomes in patients with low to moderate risk; however, outcome data from demographically diverse populations and patients who are medically complex are lacking. Objective: To compare hospitalizations, medication adherence, and cardiovascular risk factor control between participants in HBCR vs CBCR. Design, Setting, and Participants: This retrospective cohort study was conducted among patients in Kaiser Permanente Southern California (KPSC), an integrated health care system serving approximately 4.7 million patients, who participated in CR between April 1, 2018, and April 30, 2019, and with follow-up through April 30, 2020. Data were analyzed from January 2021 to January 2022. Exposures: Participation in 1 or more HBCR or CBCR sessions. Main Outcomes and Measures: The primary outcome was 12-month all-cause hospitalization. Secondary outcomes included all-cause hospitalizations at 30 and 90 days; 30-day, 90-day, and 12-month cardiovascular hospitalizations; and medication adherence and cardiovascular risk factor control at 12 months. Logistic regression was used to compare hospitalization, medication adherence, and cardiovascular risk factor control, with inverse probability treatment weighting (IPTW) to adjust for demographic and clinical characteristics. Results: Of 2556 patients who participated in CR (mean [SD] age, 66.7 [11.2] years; 754 [29.5%] women; 1196 participants [46.8%] with Charlson Comorbidity Index ≥4), there were 289 Asian or Pacific Islander patients (11.3%), 193 Black patients (7.6%), 611 Hispanic patients (23.9%), and 1419 White patients (55.5%). A total of 1241 participants (48.5%) received HBCR and 1315 participants (51.5%) received CBCR. After IPTW, patients who received HBCR had lower odds of hospitalization at 12 months (odds ratio [OR], 0.79; 95% CI, 0.64-0.97) but similar odds of adherence to ß-blockers (OR, 1.18; 95% CI, 0.98-1.42) and statins (OR, 1.02; 95% CI, 0.84-1.25) and of control of blood pressure (OR, 0.98; 95% CI, 0.81-1.17), low-density lipoprotein cholesterol (OR, 0.98; 95% CI, 0.81-1.20), and hemoglobin A1c (OR, 0.98; 95% CI, 0.82-1.18) at 12 months compared with patients who received CBCR. Conclusions and Relevance: These findings suggest that HBCR in a demographically diverse population, including patients with high risk who are medically complex, was associated with fewer hospitalizations at 12 months compared with patients who participated in CBCR. This study strengthens the evidence supporting HBCR in previously understudied patient populations.

Urgent PC Versus a Generic Posterior Tibial Neurostimulator for Overactive Bladder: A Retrospective Noninferiority Study.

OBJECTIVE: The aim of the study was to determine whether a generic posterior tibial neurostimulator was noninferior to Urgent PC in the treatment of nonneurogenic OAB, urgency urinary incontinence, and mixed urinary incontinence. Secondary outcomes include rates of starting and completing 3 months of maintenance therapy, treatment success after 3 months, and adverse events. METHODS: We performed a retrospective cohort analysis of women whose nonneurogenic OAB, urgency urinary incontinence, or mixed urinary incontinence was treated with either Urgent PC or a generic posterior tibial neurostimulator. Previous research shows a 55% treatment success rate for posterior tibial nerve stimulation (PTNS). To demonstrate noninferiority with a limit of 14% and 80% power, our analysis required 157 patients per group. RESULTS: We included 267 Urgent PC and 234 generic patients and excluded 51 patients from analysis. A per-protocol analysis demonstrated treatment success in 55.3% (121 of 219) of the Urgent PC and 48.6% (85 of 175) of the generic cohort (P = 0.187). An intention-to-treat analysis showed treatment success in 45.3% (121 of 267) of the Urgent PC and 36.3% (85 of 234) of the generic cohort (P = 0.690). There were no significant differences in rates of starting (82.2% vs 78.2%, P = 0.409) or completing (79.9% vs 70.9%, P = 0.129) 3 months of maintenance therapy, treatment success after 3 months (78.5% vs 73.8%, P = 0.485), and adverse events (0.37% vs 0.85%, P = 1.000) in the Urgent PC versus generic group, respectively. CONCLUSIONS: In this cohort of women undergoing PTNS for nonneurogenic OAB, urgency urinary incontinence, or mixed urinary incontinence, the generic neurostimulator demonstrated noninferior rates of treatment success compared with Urgent PC.

Retrospective assessment of antimicrobial stewardship initiative in outpatient use of ertapenem for uncomplicated extended spectrum beta lactamase Enterobacteriaceae urinary tract infections.

BACKGROUND: Urinary tract infections (UTI) are often over-diagnosed and over-treated, which can induce and select for resistant pathogens. After observing wide-spread outpatient use of ertapenem, a broad-spectrum antibiotic, a structured antimicrobial stewardship initiative (ASI) to improve appropriate antimicrobial prescribing was undertaken. ASI objectives were to achieve a goal of reducing ertapenem utilization for extended spectrum beta lactamase Enterobacteriaceae (ESBL-EB) UTI by 10% and evaluate the clinical outcomes associated with the ASI. METHODS: A pre-to-post cohort study was conducted at a single-center integrated healthcare system between November 1, 2014 and February 26, 2017. An intensive, 90-day, pharmacist-driven, structured ASI was implemented between November 1, 2015 and January 29, 2016. Female patients aged ≥18 years who were treated for an uncomplicated, ESBL-EB urinary tract infection (UTI) were included. Primary outcome was clinical resolution defined as cure, persistence, relapse and recurrence. Secondary outcome measured was monthly ertapenem use expressed as number of days of therapy (DOT)/1000 adjusted patient days (APD). Segmented regression analysis for interrupted time series was performed to estimate ASI intervention effect. RESULTS: A total of 184 patients were included in the study. Ertapenem utilization decreased from 0.0145 DOT/1000 APD in Nov. 2014 to 0.0078 DOT/1000 APD Feb. 2017(p < 0.01). The mean ertapenem DOT declined 19% overall from the pre vs. post intervention periods (32 vs 26, p < 0.01). Frequency of recurrent UTIs between treatments did not significantly differ and no adverse effects were reported in patients treated with aminoglycosides. CONCLUSIONS: A structured ASI for uncomplicated ESBL-EB UTI was associated with a clinically meaningful decrease in ertapenem utilization and once-daily, 5-day aminoglycoside treatment was well-tolerated.

Predictors of hepatitis A immunity in adults in California in order to better utilize hepatitis A vaccine.

BACKGROUND: Hepatitis A vaccine recommendations now include homelessness, illegal drug use, and HIV, as well as traditional risk factors and travel to areas endemic for hepatitis A. We examined a large diverse population for predictors of Hepatitis A immunity in order to better utilize Hepatitis A vaccine. METHODS: We performed a cross-sectional descriptive study of members of a large integrated health plan with a test for Hepatitis A Immunoglobulin G (IgG) between January 1st, 2007, and December 31st, 2017. Exclusion criteria included age <18 years, <6 months of continuous enrollment, and Hepatitis A vaccine prior to Hepatitis A test. Variables of interest were age, gender, primary language spoken, ethnicity/race, neighborhood household income, and history of travel or history of jaundice. Multivariable logistic regression was performed to evaluate the association of risk factors on Hepatitis A immunity. RESULTS: Of the 318,170 persons ≥ 18 years tested for Hepatitis A immunity, 155, 842 persons had a reactive Hepatitis A IgG test (49%). The lowest prevalence was for Whites at 28.1% followed by Blacks at 35.8%. Hispanics and Asian/Pacific Islanders had prevalence rates of 63% and 68.2% respectively. In adjusted analyses, Asian/Pacific Islanders, Hispanics and Blacks were 5.17, 3.44 and 1.42 times more likely to have Hepatitis A immunity than Whites. Those that spoke Spanish or language other than English or Spanish as their primary preferred language were 6.11 and 3.27 time more likely to have immunity than English speakers. Known travel history conferred a 2.16 likelihood of Hepatitis A immunity. CONCLUSIONS: Persons of Hispanic and Asian/Pacific Islander background as well as persons with a preferred spoken language other than English have a high prevalence of Hepatitis A immunity. Testing for Hepatitis A immunity prior to vaccination should be considered for these groups.

Prevalence and Characteristics of Chronic Hepatitis C Among Asian Americans Are Distinct From Other Ethnic Groups.

GOAL: The goal of this study was to determine the prevalence and characteristics of chronic hepatitis C (CHC) among Asian Americans compared with other ethnicities. BACKGROUND: Chronic hepatitis C virus (HCV) affects an estimated 2.7 million in the United States, but there are limited data on HCV among Asian Americans. STUDY: A total of 3,369,881 adults over the age of 18 who were patients of the integrated health care system in Southern California and 4903 Asian participants at community hepatitis screenings were included in a cross-sectional study. Variables included HCV serology, HCV genotype, comorbidities, and coinfections. RESULTS: The prevalence of CHC was 1.3% in the general population (8271 adults) and 0.6% among Asians. The prevalence of CHC was significantly higher in the 1945-1965 birth cohort with 2.7% (5876) in the general population and 1.0% (313) among Asians (P<0.001). Asians had the highest rates of hepatitis B coinfection (2.9% vs. 0.2%, P<0.001). The distribution of genotypes among Asians differed from the general population with the most common genotype being 1b (27.5%) and a higher presence of genotype 6 (9.5%) (P<0.001). The presence of cirrhosis was 17.6% in Asians. Disaggregated Asian data showed that CHC was highest among Vietnamese and Cambodian and that genotype 6 was predominant among these 2 subgroups. CONCLUSIONS: The prevalence of chronic HCV was significantly lower in Asians compared with other ethnicities. However, disaggregated data among Asians showed the highest prevalence rates among adults from Vietnam and Cambodia.
