Abstract
Objectives Reducing nursing home hospitalizations for ambulatory care sensitive conditions (ACSC) has been identified as
an opportunity to improve patient well-being and reduce costs. The aim of this study was to identify number of hospitalizations for ACSCs for nursing home residents in a Swiss national sample, examine demographic characteristics of
nursing home hospitalizations due to ACSCs, and calculate hospital expenses from these hospitalizations.
Methods Using merged hospital administrative data with payment data based on diagnosis-related groups (DRGs) for the
year 2013, we descriptively examined nursing home residents who were 65 years of age or older and were admitted to an
acute care hospital.
Results Approximately 42% of all nursing home admissions were due to ACSCs. Payments to Swiss hospitals for ACSCs
can be estimated at between 89 and 105 million Swiss francs in 2013.
Conclusions A sizable share of hospitalizations for nursing home residents is for ACSCs, and the associated costs are
substantial. Programs and policies designed to reduce these potentially avoidable hospitalizations from the nursing home
setting could lead to an increased patient well-being and lower costs.

Introduction
Reducing preventable hospitalizations of nursing home
residents is important to the health and well-being of
nursing home residents (Ouslander and Maslow 2012;
Walsh et al. 2012). Hospitalizations of frail, elderly persons
with multiple chronic conditions are often related to loss of
functional ability, delirium, cognitive decline, falls, hospital-acquired infections, and discontinuity of medications
(Boockvar et al. 2004; Dwyer et al. 2014; Palese et al.
2016; Zisberg et al. 2016). Several estimates show that in
the USA and Canada, between 20 and 60% of hospitalizations from nursing homes are considered preventable (Mcandrew et al. 2016; Ouslander et al. 2010;
Walker et al. 2009; Walsh et al. 2012). These hospitalizations are not only a major burden to residents but also a
substantial financial burden to the health-care delivery
system, with the costs of a hospitalization averaging
between $8000 and $20,000 in the USA (Axon et al. 2015;
Grabowski et al. 2007; Mcandrew et al. 2016; Walsh et al.
2010; Xing et al. 2013).

Preventable—avoidable, inappropriate, or unnecessary—hospitalizations fall into two groups: hospitalizations
which could have been avoided with evidence-based,
chronic disease management, prevention of acute deteriorations of chronic conditions, or hospitalizations for conditions which could have been treated in the nursing home.
Ambulatory care sensitive conditions (ACSCs) are a group
of conditions which include pneumonia, chronic obstructive pulmonary disease (COPD), or congestive heart failure
(CHF), among others, and are one of the approaches to
measure preventability. Research conducted in the USA
suggests that this set of conditions can be effectively and
safely managed in the primary care setting when early
detection and adequate chronic disease management are in
place (Mcandrew et al. 2016; Walsh et al. 2012). Identifying ACSCs can serve as an approximation of potentially
preventable hospitalizations, although the effective management of these conditions outside the hospital setting
depends on a variety of factors. For example, the decision
for or against an ED visit or hospitalization is guided by
residents’ and families’ preferences, the presence of
advance care planning, do-not hospitalize and do-not
resuscitate orders, timely availability of qualified staff,
availability of diagnostic and therapeutic interventions in
the nursing home, and the acuteness and severity of the
condition (Ouslander and Maslow 2012; Renom-Guiteras
et al. 2014). Finally, reimbursement policies might favor
hospitalizations (Ashton 2014).
ACSCs were developed for the primary care setting and
have been used for both research and policy analysis
(Billings et al. 1993; Purdy et al. 2009; Weissman et al.
1992). Several approaches exist in the literature as to which
conditions are considered sensitive to ambulatory care
(Ansari et al. 2012; Billings et al. 1993; Millman 1993;
Purdy et al. 2009; Weissman et al. 1992). Recently, expert
panels in the USA and Canada developed groups of conditions specifically for nursing home residents (Walker
et al. 2009; Walsh et al. 2012). While there were some
inconsistencies in the groups of ACSCs identified, consensus was reached regarding the inclusion of asthma,
cellulitis, CHF, COPD, dehydration, gastroenteritis, diabetes complications, hypertension, pneumonia, urinary
tract infection (UTI), seizures, and injuries from falls/
fractures. Typically, in case of exacerbation of any of these
conditions, many residents would need to be treated in the
hospital. However, preventing ACSCs is achieved through
effective monitoring of resident symptoms in nursing
homes, in combination with an interprofessional approach
to discuss treatment goals and procedures, to avoid exacerbations when possible. For example, in case of an acute
situation, the resident might remain in the nursing home for
palliative care. Similarly, residents with a tentative diagnosis of fracture will go to the ED; however, an effective
123
fall management program might prevent fall-related
injuries.
While ACSCs do not capture all the factors which
contribute to a decision to hospitalize (...truncated)
