    The present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

    Objectives: The aim of this study was to examine whether coordination between healthcare providers at an inpatient rehabilitation facility and healthcare providers in a community setting improves osteoporosis medication use in the community. Methods: In 2012, a coordination project between an inpatient geriatric rehabilitation facility located in north-central Israel and general practitioners in the community setting was initiated. In this retrospective pseudo-experimental study, we compared osteoporosis medication use among patients who were hospitalized at the facility following an osteoporotic fracture during 2011–2012, and who constituted the control group (n=120), and patients who were hospitalized at the facility during 2013–2015, and who constituted the trial group (n=129). Data were collected from the patients' records and from records of the health maintenance organization concerning medications issued to the patients by pharmacies. Results: Differences were observed between the trial and the control group in osteoporosis medication management by healthcare providers, both at the inpatient rehabilitation facility and in the community, suggesting favorable trends. However, osteoporosis medication use in the community was slightly lower in the trial group, then in the control group (32.8% vs. 34.2%, respectively). A regression analysis indicated that the only variable predicting use of osteoporosis medications in the community was a previous diagnosis of osteoporosis in the community. Conclusions: The study results indicate that mere coordination between the healthcare settings is insufficient in order to ensure continued care in the community, emphasizing the need for an osteoporosis coordinator.
