Discontinuity in care: Practice closures among primary care providers and patient health care utilization.

We evaluate the consequences for patients of being matched to a new primary care provider due to practice closures. Using an event study and population-level data of patients and providers in Denmark, we find that the transition between providers is smooth; among re-matched patients, there is little change in primary care utilization at the extensive margin. Second, we document a 17% increase in fee-for-service per visit and a large increase in the probability that the patient initiates drug therapy targeting chronic and underdiagnosed diseases (hypertension, hyperlipidemia, and diabetes).

A systematic survey of regional multi-taxon biodiversity: evaluating strategies and coverage.

Background: In light of the biodiversity crisis and our limited ability to explain variation in biodiversity, tools to quantify spatial and temporal variation in biodiversity and its underlying drivers are critically needed. Inspired by the recently published ecospace framework, we developed and tested a sampling design for environmental and biotic mapping. We selected 130 study sites (40 × 40 m) across Denmark using stratified random sampling along the major environmental gradients underlying biotic variation.
