Use Of Mechanical Ventilation By Patients With And Without Dementia, 2001 Through 2011, Tara Lagu, Marya Zilberberg, Jennifer Tjia, Penelope Pekow, Peter Lindenauer Nov 2014

Use Of Mechanical Ventilation By Patients With And Without Dementia, 2001 Through 2011, Tara Lagu, Marya Zilberberg, Jennifer Tjia, Penelope Pekow, Peter Lindenauer

Jennifer Tjia

Increasing demand for US critical care resources, including beds, intensivists, and invasive mechanical ventilation (IMV),has placed substantial strain on the critical care system. Since 2000, elderly patients treated in the intensive care unit have received higher intensity care (and have experienced lower mortality rates) than historical cohorts. Yet certain populations of elderly patients exposed to intensive care experience substantial long-term adverse effects, including functional decline and excess mortality. Patients with dementia receiving IMV, for example, are at high risk for delirium, which confers a 3.2-fold increased risk of 6-month mortality. The increasing use of aggressive therapies suggests that demand for …

Challenge Of Changing Nursing Home Prescribing Culture, Jennifer Tjia, Jerry Gurwitz, Becky Briesacher Feb 2012

Challenge Of Changing Nursing Home Prescribing Culture, Jennifer Tjia, Jerry Gurwitz, Becky Briesacher

Jennifer Tjia

This article described a framework for improving prescribing in nursing homes (NH) by focusing on the whole facility as a system that has created a "prescribing culture." We offered this paradigm as an alternative to focused interventions that target prescribers only. We used the example of atypical antipsychotics to illustrate the approach. We also highlighted elements of the NH culture change movement that are germane to medication prescribing, and illustrated which elements of NH culture were shown to be associated with suboptimal quality of care. We concluded by describing current models, including our study funded by the Agency for Healthcare …
