RESUMO
OBJECTIVES: Studies evaluating telemedicine critical care (TCC) have shown mixed results. We prospectively evaluated the impact of TCC implementation on risk-adjusted mortality among patients stratified by pre-TCC performance. DESIGN: Prospective, observational, before and after study. SETTING: Three adult ICUs at an academic medical center. PATIENTS: A total of 2,429 patients in the pre-TCC (January to June 2016) and 12,479 patients in the post-TCC (January 2017 to June 2019) periods. INTERVENTIONS: TCC implementation which included an acuity-driven workflow targeting an identified "lower-performing" patient group, defined by ICU admission in an Acute Physiology and Chronic Health Evaluation diagnoses category with a pre-TCC standardized mortality ratio (SMR) of greater than 1.5. MEASUREMENTS AND MAIN RESULTS: The primary outcome was risk-adjusted hospital mortality. Risk-adjusted hospital length of stay (HLOS) was also studied. The SMR for the overall ICU population was 0.83 pre-TCC and 0.75 post-TCC, with risk-adjusted mortalities of 10.7% and 9.5% (p = 0.09). In the identified lower-performing patient group, which accounted for 12.6% (n = 307) of pre-TCC and 13.3% (n = 1671) of post-TCC ICU patients, SMR decreased from 1.61 (95% CI, 1.21-2.01) pre-TCC to 1.03 (95% CI, 0.91-1.15) post-TCC, and risk-adjusted mortality decreased from 26.4% to 16.9% (p < 0.001). In the remaining ("higher-performing") patient group, there was no change in pre- versus post-TCC SMR (0.70 [0.59-0.81] vs 0.69 [0.64-0.73]) or risk-adjusted mortality (8.5% vs 8.4%, p = 0.86). There were no pre- to post-TCC differences in standardized HLOS ratio or risk-adjusted HLOS in the overall cohort or either performance group. CONCLUSIONS: In well-staffed and overall higher-performing ICUs in an academic medical center, Acute Physiology and Chronic Health Evaluation granularity allowed identification of a historically lower-performing patient group that experienced a striking TCC-associated reduction in SMR and risk-adjusted mortality. This study provides additional evidence for the relationship between pre-TCC performance and post-TCC improvement.
RESUMO
BACKGROUND: Evidence-based guidelines for promoting physical activity have been produced, yet sparse information exists on the dissemination of effective interventions. The purpose of this study was to better understand the dissemination of physical activity interventions across the United States, focusing particularly on evidence-based guidelines. DESIGN: A cross-sectional study was conducted in the U.S. that was organized around a modified version of the diffusion of innovations theory. SETTING/PARTICIPANTS: Respondents (n=49) were the physical activity contact person (e.g., program administrator, health educator) in each state or territorial health department. MAIN OUTCOME MEASURES: Seven specific programs and policies relating to physical activity intervention were examined as dependent variables. Five additional domains--organizational climate, awareness, adoption, implementation, and maintenance--framed a set of independent variables. RESULTS: The most important factor related to decision making was the availability of adequate resources. Most respondents (89.8%) were aware of evidence-based guidelines to promote physical activity. However, less than half of the respondents (41%) had the authority to implement evidence-based programs and policies. A minority of respondents reported having support from their state governor (35.4%) or from most of their state legislators (21.3%). Several key factors were associated with the adoption of evidence-based interventions, including the presence of state funding for physical activity, whether the respondent participated in moderate physical activity, presence of adequate staffing, and presence of a supportive state legislature. CONCLUSIONS: Awareness of the importance of promoting physical activity is relatively high in state and territorial health departments; however, the levels of internal support within the health department appear to outweigh any outside support from elected officials.
