Immediately after the approval of direct-acting antiviral medications for the treatment of hepatitis C virus (HCV) in 2013, state Medicaid programs limited access to these expensive treatments based on liver disease stage, absence of active alcohol or substance use, and prescriber limitations. New York State fee-for-service (FFS) Medicaid eliminated these requirements in May 2016, but the effect on providers and patients obtaining prior authorization (PA) from Medicaid managed care organizations (MCOs) was unknown. We used a mixed methods approach to assess whether the removal of HCV treatment restrictions was associated with changes in Medicaid MCOs' PA approval processes and length of time to treatment initiation at two large urban New York City provider organizations participating in Project INSPIRE, an HCV care coordination demonstration project. ⋯ Univariate analysis of the Project INSPIRE participant data suggests a decrease in the percentage of participants with insurance/PA-related treatment delays pre- versus post-policy change (23% versus 15%, p value = 0.02). Interrupted time series analysis found a 2 percentage point decrease (p value = 0.02) in the proportion of PAs each month with insurance-related treatment delays that was attributable to policy change. These results from two urban clinics indicate New York State FFS Medicaid's policy change for HCV treatment may have been associated with some changes in Medicaid MCO PA decisions, but MCO PA denials and treatment delays were still observed "on the ground" by clinic staff.

We sought to find a method that improves HIV estimates obtained through time-location sampling (TLS) used to recruit most-at-risk populations (MARPs). The calibration on residuals (CARES) method attributes weights to TLS sampled individuals depending on the percentile to which their logistic regression residues belong. ⋯ From each pseudo-population, 1000 TLS samples were drawn, and the HIV prevalence estimated by the TLS method and by the CARES method were recorded and compared with the HIV prevalence of the 9591 men. Results showed that the CARES method improves estimates given by the TLS method by getting closer to the real HIV prevalence.

Epidemiological studies on the impact of determining environmental factors on human health have proved that temperature extremes and variability constitute mortality risk factors. However, few studies focus specifically on susceptible individuals living in Portuguese urban areas. This study aimed to estimate and assess the health burden of temperature-attributable mortality among age groups (0-64 years; 65-74 years; 75-84 years; and 85+ years) in Lisbon Metropolitan Area, from 1986-2015. ⋯ It was observed that the proportion of deaths attributed to exposure to extreme heat is higher than moderate heat. As with cold temperatures, people aged 85+ years are the most vulnerable age group to heat, 8.4% (95% CI: 3.9%, 2.7%), and mostly due to extreme heat, 1.3% (95% CI: 0.8-1.8%). These results provide new evidence on the health burdens associated with alert thresholds, and they can be used in early warning systems and adaptation plans.
