Background
Due to a changing health care system and the desire to age in place (the desire to remain living at home as long as possible [
1,
2]), care for older people is rapidly shifting from an institutional to a primary care setting. As a consequence, primary care professionals are increasingly confronted with patients who suffer from degenerative diseases and multiple chronic conditions. Such complex health problems frequently go together with pain [
3,
4]. It has been estimated that between 25 and 50 % of older people who live at home regularly experience pain [
5]. Despite these numbers, research evidence suggests that barriers at a professional, patient and health system level limit older people’s access to adequate pain care services [
6‐
8]. For instance, health care professionals may hold misconceptions and inherent bias, or may lack the knowledge or experience to adequately evaluate and treat pain in older patients [
9‐
12]. In addition, older people themselves may avoid reporting their pain to health care professionals, use vague and varying terms to describe their complaints, or are reluctant to take medications [
7,
13‐
16]. Health systems may pose practical constraints to adequate pain care, such as restricted access to services or financial burdens [
8,
14]. As a result of these barriers, older people’s pain remains often undertreated or not recognized by health professionals [
10,
17‐
19]. When undermanaged or unmanaged, pain can cause adverse health outcomes such as depression, anxiety, cognitive impairment and social isolation, which negatively impacts on older people’s health and social wellbeing, and, consequentially, increases the burden on health care systems [
4,
10,
18,
20‐
23]. It is therefore essential that health professionals in primary care expand access to pain care by recognizing pain problems at an early stage and by providing pain care that is tailored to the older person’s individual need.
In response to the growing pressure on health care systems and the subsequent strain on elderly care services, governments, policy makers and researchers have been testing and implementing a type of care model characterized as comprehensive. Comprehensive care models provide a framework for the organization and delivery of integrated, patient-centered care, often in a primary or chronic care setting [
24]. One of such models is the Geriatric Care Model [
25], a comprehensive primary care model for frail, older people in the Netherlands based on the Chronic Care Model [
26]. An important premise of the Geriatric Care Model is that, whenever feasible, treatment choices and decision making processes are guided by older people’s own needs and preferences. Within this premise, the Geriatric Care Model has three main objectives: to identify older people’s health and care needs at a timely stage, to enhance coordination between professionals at an individual and regional level, and to encourage older people’s involvement in their own care process. Central to the Geriatric Care Model is a proactive home visit program with comprehensive geriatric assessments (CGAs) administered by practice nurses [
25]. In the Netherlands, practice nurses support primary care physicians in providing medical care for patients with chronic conditions, and mainly carry out organizational and guideline-based activities [
27]. A CGA is a multidimensional evaluation that determines an older person’s medical, psychosocial, functional and environmental resources [
25]. Together with, for instance, cognitive and functional status, pain is considered a major CGA domain, and is often assessed by means of unidimensional pain scales (such as the widely-used numerical rating scale (NRS)) or multidimensional pain scales [
28]. Within the Geriatric Care Model, practice nurses use GCA results to further explore an older person’s pain care needs, and to present possible management and treatment options. During this process, practice nurses aim to actively involve older people in the decision making process, encouraging them to make a decision that best fits their needs. Pain care-related decisions are reported in tailored pain care plans.
The Geriatric Care Model may expand access to pain care for frail, older people in primary care in several ways. First, research suggests that expanding the primary care workforce to include health professionals that are not physicians (e.g. nurses) can maintain access to care, and that that nurse supplementation in primary care generally improved the quality of care delivery [
29,
30]. Second, by proactively exploring pain complaints through administering a CGA, practice nurses may indentify pain and pain care needs at a more timely stage. Third, CGAs ensure that all aspects of an older person’s health and wellbeing are asked about and specified, and are often mentioned as an essential method for planning pain management strategies that are tailored to older people’s needs, preferences and environment [
16,
31‐
35]. Finally, visiting older people in their home environment can provide practice nurses with important information about an older person’s context and lifestyle, and helps overcome logistical barriers to care [
35]. The home setting can also reduce the power imbalance intrinsic to a client-nurse interaction in an institutionalized environment by increasing people’s agency [
36,
37], which allows for a more collaborative relationship between caregiver and receiver. A collaborative relationship facilitates the recognition and targeting of pain management needs and goals, and encourages adherence to pain management [
38,
39].
To understand whether in-home, practice nurse-led CGAs have the potential to overcome barriers to pain relief and expand access to tailored pain care for frail, older people, it is essential to gain insight in how often older people who received a CGA reported pain complaints, and to learn more about the pain care-related decisions made by older people with pain. We therefore used data from a trial that evaluated the effectiveness, cost-effectiveness and implementation process of the Geriatric Care Model to investigate whether new pain cases were identified by practice nurses during proactive, in-home CGAs, and to explore which pain management decisions were made as a result of these CGAs. By reporting our results, we aim to contribute to a better understanding of ways in which access to tailored pain care for frail, older people can be expanded.
Methods
Study design and participants
We used cross-sectional, first-time assessment data from the older Adults: Care in Transition (ACT) study, a 2-year clinical trial that implemented the geriatric care model among 1147 patients of 65 years and older from 35 primary care practices in the Netherlands [
25]. Since the cluster assigned to the primary care practice designated the starting time of the intervention, older people participating in the ACT study received their first assessment at different times during the trial period. We included all ACT participants who received at least one home visit and assessment (
N = 869). Due to the exclusion of 82 individuals with missing or incomplete first-time assessment data, our final study sample consisted of 781 older people. ACT participants were recruited in three steps. First, primary physicians selected patients based on a polypharmacy criterion (five or more drugs prescribed in the last three months) [
40]. Subsequently, primary care physicians included all other patients who met a multidimensional definition of frailty (i.e., a loss of resources and a reduced reserve capacity for dealing with stressors in multiple domains of human functioning, such as the physical, psychological and social domain [
41]). Exclusion was based on the following criteria: residence outside area of practice registration; residence in a nursing home; cognitive impairment or impaired mental status; critical or terminal illness [
25]. Finally, eligible individuals were then contacted by telephone and asked to consider study participation. Final eligibility was established with the Program on Research for Integrating Services for the Maintenance of Autonomy case-finding tool for disability (PRISMA-7) [
42]. Individuals with a PRISMA-7 score 3 or higher were considered frail, and invited to participate in the study [
40].
The geriatric care model
The Geriatric Care Model was implemented in two regions in the Netherlands between 2010 and 2014. The model aims to enable productive interactions between activated, informed patients and a proactive, prepared care team. Care teams consist of practice nurses, a geriatric expert team (a geriatric nurse and an elderly care physician), a family physician, a pharmacist, and care professionals involved in an older person’s care process. Practice nurses played a central role in the implementation of the Geriatric Care Model: they carried out in-home CGA’s and performed coordinating tasks such as arranging care and support services and organizing multidisciplinary team consultations (MTCs, that were attended by the practice nurse, the primary care physician, the geriatric expert team, a pharmacist and other relevant health care professionals) to discuss clients with complex health and care situations.
Every six months, older people received two proactive home visits from a practice nurse. During the first visit, the practice nurse carried out a CGA using the multidimensional web-based Community Health Assessment version 9.1 of the Resident Assessment Instrument (RAI-CHA) [
43]. By means of a structured list of items, RAI-CHA users explore their client’s health problems and care needs. Pain-related items include items about frequency, intensity, duration and ability to control the pain. RAI-CHA items trigger Client Analysis Protocols (CAPs) in several domains (e.g. physical wellbeing, social functioning, living and safety). The CAPs help RAI-CHA users identify possible targets for care, and support care and service. When a CAP was triggered or a practice nurse observed a health problem or care need independently from the RAI instrument, she discussed possible management options with the primary care physician and drafted a tailored care plan. For each CGA result, practice nurses reported in the care plan whether the primary care physician had been aware of their patients’ problem or need or not. During the second visit, approximately two weeks after the first visit, the practice nurse addressed the assessment results with the older person. They explored the older person’s wishes regarding further care, informed and advised them about suitable care options, and stimulated their involvement in the decision making process. In case an older person desired a plan for their health problem or care need, a care goal and an action or agreement were formulated and recorded in a care plan. At all times, older people were given the opportunity to edit or remove care plan content. All participants consented to the use of the care plan for research purposes.
Data collection
We used tailored care plans (
N = 781) written by practice nurses and based on first-time, in-home CGA results related to pain (including practice nurses’ own observations) to report the following care plan outcomes: ‘prevalence of any type of pain’, ‘location and cause of pain’, ‘prevalence of new pain cases’ and ‘prevalence of new pain action plans’. We used baseline data from the ACT study to report health-related and sociodemographic characteristics of our study population [
25]. ACT study baseline data were collected by trained project interviewers by means of computer-assisted interviewing. Health-related characteristics included quality of life, functional capacity and self-reported chronic diseases. Quality of life was measured with the 12-item Short Form questionnaire (SF-12), which measures quality of life using a mental component summary score (MCS) and a physical component summary score (PCS) [
44]. Functional capacity was measured using the Katz-15 index of Independence in Activities of Daily Living (IADL) [
45], and calculated using a sum score. Four major self-reported diseases (Diabetes Mellitus, depression, cancer and cerebrovascular disease) were assessed with The Older Persons and Informal Caregivers Survey Minimum DataSet (TOPICS-MDS) [
46]. Sociodemographic characteristics included sex, age, living situation (independent alone, independent with others, home for the aged or residential care), and education (primary, secondary, higher).
Data processing and analysis
Care plans were analyzed as follows: each care plan was read by two researchers who independently analyzed the care plan for the presence of pain (present, not present), new pain cases (present, not present, missing) and pain action plans (present, patient currently has adequate action plan, patient refuses action plan, reason action plan not present unknown). Care plans that mentioned pain as a CGA result were analyzed for the presence of a location and cause of the pain. If a care plan featured a pain action plan, the action plan was categorized as either a therapeutic intervention or a non-therapeutic intervention. Prevalence of pain was assessed by calculating the number of care plans that mentioned pain (both recently developed and persistent pain, and pain of different frequencies, patterns and intensities) as a result of a CGA (i.e. when the RAI instrument triggered a pain-CAP or a practice nurse identified pain independently from RAI). Location and cause of pain was assessed by categorizing practice nurses’ own care plan descriptions of pain location and cause, and by subsequently calculating the number of times each category was present in a care plan. ‘Location’ categories were as follows: back & neck, buttocks, joints, leg or legs, arm or arms, hand or hands, foot or feet, head, abdomen, respiratory tract, genitals, other. ‘Cause’ categories were as follows: arthritis of one or more joints, rheumatoid arthritis, polymyalgia, osteoporosis, peripheral arterial disease, persistent pain after recent trauma, persistent pain after past trauma, persistent pain after recent surgery, cancer pain, pain as a side effect of medication, cause pain unknown, other. Prevalence of new pain cases was assessed by calculating the number of care plans that mentioned that a pain complaint had not been identified by a primary care physician. Prevalence of pain action plans was assessed by calculating the number of care plans that contained both a pain care-related care goal and a pain care-related agreement or action. We distinguished the following two categories of pain action plans: (1) action plans that contained therapeutic interventions (pharmacological interventions and non-pharmacological interventions) and (2) action plans that contained non-therapeutic interventions (education-related interventions, continuity of care-related interventions or ongoing assessment-related interventions). The outcomes of the independent analyses were compared, and in case researchers disagreed, a final decision was reached by consensus.
We used descriptive statistics to analyse care plan data and ACT study baseline data. We performed independent T-tests and chi-square tests to compare health-related and sociodemographic characteristics of older people with and without any type of pain and with and without a pain care plan. Data were analyzed using SPSS Statistics version 20.
