Long-term effects of SARS-CoV-2 vaccination in the nursing home setting.

BACKGROUND: SARS-CoV-2 vaccination has significantly reduced infection, hospitalization, and lethality rates among nursing home (NH) residents, but durability of vaccine effects remains unknown. This study investigated the long-term impact of BNT162b2 SARS-CoV-2 vaccine on breakthrough infection rates in the NHs of Florence, Italy. METHODS: Participants included residents living in Florence NHs as of April 1st, 2021, who had completed the primary SARS-CoV2 vaccination course by February 15th, 2021. Weekly rates of breakthrough infection were calculated between April 1st and October 31st 2021, with 7-day incidence defined as the number of new confirmed SARS-CoV-2-positive residents over the vaccinated resident census. Hospital admissions and deaths were recorded from local administrative and clinical sources. Patients admitted to NHs after April 1st were excluded to avoid confounding effect of different vaccination timing. RESULTS: Among 2271 vaccinated residents (mean age 86.6, 74% female), we recorded 105 cases of breakthrough infections. Rates of breakthrough infection remained very low in the 6 months after vaccination, but started to rise over the following months, peaking at 0.94%, and then became stable around 0.2%-0.3%. Over the study period, infection rates remained low as compared to the incidence of SARS-CoV-2 infection during pre-vaccination period. Overall hospitalization and lethality rates were 8%. CONCLUSIONS: Among vaccinated NH residents, rates of breakthrough SARS-CoV-2 infection, hospitalization and lethality remained low up to 9 months following primary vaccination course. A mild resurgence of SARS-CoV-2 infection, after 6 months from vaccination, suggests a decline of vaccine effectiveness in preventing transmission.

Telehealth Management and Risk Stratification of Older Patients With Chronic Heart Failure During COVID-19 Pandemic: Prognostic Evaluation of the TeleHFCovid19-Score.

OBJECTIVES: To evaluate 6-month risk stratification capacity of the newly developed TeleHFCovid19-Score for remote management of older patients with heart failure (HF) during the coronavirus disease 2019 pandemic. DESIGN: Monocentric observational prospective study. SETTING AND PARTICIPANTS: Older HF outpatients remotely managed during the first pandemic wave. METHODS: The TeleHFCovid19-Score (0-29) was obtained by an ad hoc developed multiparametric standardized questionnaire administered during telephone visits to older HF patients (and/or caregivers) followed at our HF clinic. Questions were weighed on the basis of clinical judgment and review of current HF literature. According to the score, patients were divided in progressively increasing risk groups: green (0-3), yellow (4-8), and red (≥9). RESULTS: A total of 146 patients composed our study population: at baseline, 112, 21, and 13 were classified as green, yellow, and red, respectively. Mean age was 81±9 years, and women were 40%. Compared to patients of red and yellow groups, those in the green group had a lower use of high-dose loop diuretics (P < .001) or thiazide-like diuretics (P = .027) and had reported less frequently dyspnea at rest or for basic activities, new or worsening extremity edema, or weight increase (all P < .001). At 6 months, compared with red (62.2%) and yellow patients (33.3%), green patients (8.9%) presented a significantly lower rate of the composite outcome of cardiovascular death and/or HF hospitalization (P < .001). Moreover, receiver operating characteristic curve analysis showed a high sensibility and specificity of our score at 6 months (area under the curve = 0.789, 95% CI 0.682-0.896, P < .001) with a score <4.5 (very close to green group cutoff) that identified lower-risk subjects. CONCLUSIONS AND IMPLICATIONS: The TeleHFCovid19-Score was able to correctly identify patients with midterm favorable outcome. Therefore, our questionnaire might be used to identify low-risk chronic HF patients who could be temporarily managed remotely, allowing to devote more efforts to the care of higher-risk patients who need closer and on-site clinical evaluations.

Protocol for Telehealth Evaluation and Follow-up of Patients With Chronic Heart Failure During the COVID-19 Pandemic.

Because of the Coronavirus Disease 2019 (COVID-19) pandemic, we were forced to cancel scheduled visits for nearly 150 patients followed in our heart failure (HF) outpatient clinic. Therefore, we structured a telephone follow-up, developing a standardized 23-item questionnaire from which we obtained the Covid-19-HF score. The questionnaire was built to reproduce our usual clinical evaluation investigating a patient's social and functional condition, mood, adherence to pharmacological and nonpharmacological recommendations, clinical and hemodynamic status, pharmacological treatment, and need to contact emergency services. The score was used as a clinical tool to define patients' clinical stability and timing of the following telephone contact on the basis of the assignment to progressively increasing risk score groups: green (0-3), yellow (4-8), and red (≥9). Here we present our experience applying the score in the first 30 patients who completed the 4-week follow-up, describing baseline clinical characteristics and events that occurred in the period of observation.
