Question: Around 3-5% of people can be identified as chronic complex patients(CCP) and are increasingly at risk of hemorrhagic stroke.The main objective was to explore differences in risk factors and the association with outcome factors on mortality.
Materials and Methods: Multicenter and prospective cohort study from January 1 2013 to September 30 2016 among patients registered as chronic complex outpatients. To predict hazard ratios, mean survival time, and survival probabilities, multivariate Cox regression was used.
Results: 932 CCP were included (52.3% women). Average age was 82.5 years (95% CI 81.8-83.2). During a mean follow-up period of 2.8 years, 65 (6.98%) stroke episodes happened (37 (56.9%) ischemic; 28 (43.1%) hemorrhagic). The percentage of ICH almost doubled (21.0% to 43.1) after CCP diagnosis; 26.1% had polypharmacy (≥ 10), 57.6% VKA-treated patientsshowed TTR <60%, and had a higher incidence of falling (31.9% vs. 19.2%, p 0.002).The average survival time was significantly shorter associated with age (HR 1.03 95% CI 1.14-1.53, p 0.001), previous stroke (HR 13.54 95%, CI 9.23-19.81, p<0.001), antiagreggant treatment (HR 1.97 95% CI 1.21-3.21, p 0.006), anticoagulant treatment (HR 1.78 95%, CI 1.22-2.60, p 0.002), and Barthel score <60 (HR 1.43 95% CI 1.04-1.97, p 0.024).
Conclusions: Given the co-occurrence of hemorrhagic strokes with poor performance status, multi-morbidity, and polypharmacy, multi-dimensional interventions are needed to improve health outcomes.

We face an epidemic of multi-morbidity and rising complexity of health needs [1,2] resulting from changing demographics and global circumstances. In developed countries, around 3-5% of the people can be identified as chronic complex patients who are increasingly at risk of stroke [3,4]. Although the European population aged ≥ 65 years will double by 2050, there are few studies about the epidemiology of hemorrhagic stroke and the burden of unfavourable outcome and associated health care costs. The statistics about hemorrhagic stroke show high variability: lowering [3,5] against rising of incidence [6,7], or no change [8,9]. However, there is general agreement on the increase related to aging [10].

Unfortunately the intracerebral haemorrhage accounts for the shortest term survival and poor functional prognosis of all stroke types [11,12]. The prevention of these negative effects is of major importance because, nowadays, they are major issues for health and social care providers and the identification of patients likely to recover may be crucial for families confronted with a need for intensive care and medical teams with regard to direction of care [13-15]. Over the last 20-30 years, problems related to aging and hemorrhagic stroke have become a prominent issue in global healthcare, there is no recent evidence on long term survival among chronic and complex people [16-18], and in spite of existing tools to predict mortality and functional outcome there are important limitations to their application [19].

The goals of the present analysis were (i) to improve our knowledge of the epidemiology of hemorrhagic stroke and mortality risk among people registered as chronic complex outpatients and (ii) to explore risk factors differences in the association of outcome factors on survival. This review discusses how primary care might tackle these new challenges of hemorrhagic stroke among the aging population.

Materials And Methods

We carried out a a multicenter and prospective cohort study of the incidence of mortality from January 1, 2013 to September 30, 2016 among chronic complex outpatients (CCP) attending primary care teams in the Terres de l’Ebre health area in Catalonia (Spain). All people were managed by the public health system in Catalonia. Registry information was collected from the government-run healthcare provider responsible for all inpatient care in the county. The overall number of CCP registered was 3,490 people. We included a randomized sample of 932 adult patients registered in the electronic health records of primary care as CCP in the period from January 1 2013 December 31 2014. Patients were excluded if they resided in a long-term institutional setting. Alpha Risk=0.05; Precision=0.03.

Patient outcomes were followed until death or the end of the study (September 30, 2016) starting with the reporting date as CCP in the electronic health record. Data included demographics, functional, comorbidity, cognitive and social assessment, and were collected directly from the Shared Individual Intervention Plan [Pla d’intervenció individualitzat compartit (PIIC)] written and managed by the nursing service in primary care. In the PIIC, determinants related to personal factors, as well as the social and physical environment are described to provide a tailored personal approach according to the patient’s preferences in the case of hospital readmission or emergency care use and the primary caregiver. The report is updated automatically to ensure that relevant information is shared across the electronic health record. Currently, 82% of people registered as CCP have this basic information in their PIIC.


Chronic complex patient (CCP)

Definition: Those who meet at least four of the following criteria . Age (≥ 65 years old). Chronic comorbidities (≥ 4). Psychosocial disorders (cognitive impairment or psychological disorder with functional disability). Geriatric conditions such as functional disability (Barthel score <55, living in an assisted living facility, nursing home, or with in-home caregivers) or recurrent falls or fall risk. Previous high health care utilization (two unplanned hospitalizations for exacerbation of chronic pathologies or three emergency department visits in the last year). Number of active medications in the last six months (≥ 4 active medications). Living alone or with a caregiver ≥ 75 years old. The chronic complex patient [15] has been defined as a person with a chronic illness and complex clinical situations which make their management significantly far more difficult. The group also could include patients who do not meet these criteria, but are affected by other clearly complex conditions, such as schizophrenia or mental illnesses with behavioral disorders.


Individuals with current stroke diagnoses in their medical charts after inclusion into the study were considered to have experienced an incident stroke. A previous stroke was considered to be present if the medical charts included a stroke diagnosis or if the individual, a caregiver, or a relative reported the diagnosis and it was found with supporting information on medical charts or other assessments. Records of inpatient care after baseline assessment with International Classification of Diseases (10th version; ICD-10) code prefixes I60, I61, I63, I64, H34, I67, and G45; subsequent diagnoses of stroke or transient ischemic attack were compiled for all participants. All other diagnoses were based on information from assessments conducted during home visits and records from hospitals, general practitioners, and institutional care facilities. A physician comprehensively reviewed the digital medical charts of individuals.

There are problems in defining fall risk, as many studies fail to specify an operational definition, leaving room for interpretation. A fall is an unintentional event that results in the person coming to rest on the ground or another lower level (W19.9 code in the electronic health record). A fall was defined as the result of any event that caused the patient to end up on the ground against their will, according to the WHO definition [20]. We used “a clinical report in the electronic health record that a person had a fall risk or previous recurrent falls with or without any serious injury”. If a patient is thought to be high risk by medical or nursing staff, allied health, or carers, such patients will be identified as a fall risk in the PIIC. This might include a mention of the patient’s level of orientation and cognition, gait and balance, continence status, and number and types of prescribed medications, as well as number of diagnosis.


Sex: female (0) male (1)


Number CCP criteria:

Charlson comorbidity index [21]. Short version.

Current medications were asked about during the home visit and confirmed in medical records. Polypharmacy (defined as ≥ 5 daily medications): 22] ≥ 60% or <60% , or new oral anticoagulants (NOACs). Antidepressants and/or sedating or other drugs affecting the neurological system. If there was a diagnosis of “atrial fibrillation, CHA2DS2VASC [23,24] HAS-BLED [25,26] scores were included.

Recurrent falls or fall risk: no (0), yes (1).

Hypertension not controlled by therapy (≥ 160/90 mmHg): no (0), yes (1). BP was measured as an average of separate follow-up measurements in the last six months.

Alcoholism abuse vs. dependence: no (0), yes (1)

Presence of cognitive impairment [27]: a disease-specific diagnosis of cognitive impairment, without specification of sub-type or severity, was used and mesured by the Pfeiffer test: (0-2 errors) = intact intellectual functioning (1); (≥ 3 errors)=mild to severe intellectual impairment (2).

Presence of disability: Barthel score [28] ≥ 60 (1), 29]

Socio-familiar risk: score on the Gijon [30] scale 10-14 (1) ≥ 15 (2).

We conducted an intention-to-treat analysis. Patients were followed up from cohort entry as CCP to the first event occurrence (death), the end of the study period, or loss to follow-up. Categorical variables were expressed as frequencies (percentage) and quantitative variables as mean (standard deviation) or median (interquartile range). Demographic data were summarized using mean and SD or median and quartiles for continuous variables and percentages for categorical data. Data analysis information was extracted and the adjusted risk estimates and 95% confidence intervals (CI) and all two-sided statistical tests were performed at the 5% significance level. Time-toevent analysis was performed using non-parametric methods like the Kaplan-Meier and log-rank test. To predict hazard ratios, mean survival time, and survival probabilities, multivariate Cox regression was used adjusting for the following baseline characteristics and confounding and predictive factors of each event: age, sex, Charlson index, factors in the CHA2DS2VASC and HAS-BLED scales, and active treatments. The variables were included in a multivariable model Cox to identify their influence on mortality. The non-hemorrhagic group and no stroke group were considered as the reference in all analyses. All analyses were performed using IBM SPSS version 19.0.

Table 1: Baseline characteristics of CCP patients and stroke: ischemic vs. hemorrhagic.

During a mean follow-up period of 2.8 years, 65 (6.98%) stroke episodes happened [37 (56.9%) ischemic; 28 (43.1%) hemorrhagic]. The annual crude hemorrhagic stroke rate was 23.5/100,000 personyear. The percentage of hemorrhagic strokes almost doubled (21.0% to 43.1) after diagnosis as CCP. Those that suffered a stroke after registration as CCP had more comorbidities (p 0.012), higher scores in CHA2DS2VASC (p<0.001), HAS_BLED (p<0.001), a greater fall risk (40.9% vs. 18.6%, p<0.001), and higher mortality (47.0% vs. 33.3%, p 0.031) than those without a stroke episode.

The patients with hemorrhagic stroke were mostly men (62.3%, p 0.008), with more than the average number of CCP criteria (4.1 ± 1.0, p 0.028) and higher scores in the Charlson index (p<0.001), CHA2DS2VASC (p<0.001), and HAS_BLED (p<0.001). These patients also had a higher prevalence of hypertension (p 0.004) and worse control (p 0.003), more polypharmacy (p 0.002), a higher prevalence (p 0.034) of moderate dependence (Barthel <60), and a higher prevalence of fall risk (p 0.012). In total, 25% of hemorrhagic episodes happened among patients with previous ischemic stroke; the significant factors associated consistently with incident hemorrhagic stroke at baseline in univariate model are shown in Table 2. In the basic adjusted multivariate model, the significant factors were: age (HR 1.03, 95%, CI 1.14-1.05, p 0.001), previous stroke (HR 13.54, 95%, CI 9.23-19.81, p<0.001), antiagreggant treatment (HR 1.97, 95%, CI 1.21-3.21, p 0.006), anticoagulant treatment (HR 1.78, 95%, CI 1.22-2.60, p 0.002), and Barthel score

According to gender, severity (NIHSS men 8.3 ± 7.3 vs. women 8.7 ± 6.8, (p 0.816) was not significantly different. After discharge, the average Barthel score (62.3 ± 32.1 vs. 70.2 ± 31.2, p<0.001) and Rankin score (2.6 ± 1.5 vs. 3.1 ± 1.4, p 0.021) were significantly lower among women as well as the presence of moderate dependence (Barthel ≤ 60 men 43.1% vs. women 56.9%). Also the percentage of cognitive impairment was higher than among men (65.4% vs. 30.2%, p 0.006), with higher scores on the Pfeiffer test (p 0.007) and Gijon scale (0.020), and were more often users of CNS depressant drugs (84.6% vs. 46.5%, p 0.002). In the basic adjusted multivariate model, age, previous disability, and female gender were independent factors associated with poor functional outcome at discharge.

The overall mortality was significantly higher among those with hemorrhagic stroke (59.4% vs. 32.2%, p<0.001). The average survival time was significantly shorter (Figure 1) among those with hemorrhagic stroke. In the basic multivariate analyses, the outcome independent factors were: Charlson score (HR 1.13395%, CI 1.043-1.23, p 0.003), cognitive impairment (Figure 2) [HR 1.05 95%, CI 1.01-1.09, p 0.011], Barthel score heart failure (HR 1.82 95%, CI 1.44-2.29, p<0.001). The case-fatality rates were 44% at 28 days and 57% at one year.

This study describes some epidemiological differences in hemorrhagic strokes in the general population. Similarly to previous results [3], in CCP, there is an increased incidence associated with aging and the risk of ICH mortality appears to be marginally greater in men, but the women suffer more functional disability. The first step should be the prevention of ICH. Single explanatory variables associated to hemorrhagic stroke incidence were age, hypertension, previous stroke, antiagreggant and anticoagulant treatments and Barthel score <60, but we could not establish them as independent risk factors. Like in previous results [4] the older individuals become, less could be avoided the hemorrhagic stroke. The control of cardiovascular comorbidities, fall risk, and polypharmacy could be manageable clinically and related to prevention proposals but the possible impact on the outcome is an open question.

In this cohort, 25% of hemorrhagic episodes happened among patients with ischemic stroke at baseline. Following an acute stroke, breakdown of the blood brain barrier occurs, resulting in a friable intracranial vasculature. This breakdown theoretically increases the risk of intracerebral bleeding, specifically in the area of ischemia. The study provides interesting descriptive data about treating older patients on OAC. Antiplatelet drugs confer an increased risk of bleeding, but unfortunately, little data exist to suggest how long this friability lasts or what other factors may contribute [31]. Patients with polypharmacy had a significantly higher risk of major and medically relevant nonmajor bleeding than patients without polypharmacy [32]. In our study, 26.1% of hemorrhagic patients had polypharmacy (≥ 10); 57.6% of hemorrhagic patients spent more time in the subtherapeutic INR range vs. 46.7% of ischemic cases, and had a significantly higher (p<0.001) bleeding risk/year than ischemic patients; the hemorrhagic patients had a higher incidence of falling (31.9% vs. 19.2%). It seems prudent to critically review medications and to stop concomitant treatment with medications with an increased risk of interactions, sedation, or orthostatic hypotension, if feasible. Further studies are needed to examine whether new oral anticoagulants can be used more safely in elderly patients receiving multiple drug treatments [32].

Given that the falls have come to be recognized as a major threat to the safety, health and independence of elderly persons [33], the use of the evaluation of fall risk in the community could improve knowledge translation into clinical practice. Eventually, for risk factor assessment to make a difference, all risk factors identified in the risk assessment need to be addressed in the care plans, and the care plans need to be acted on.

High SBP (≥ 160 mmHg) and atrial fibrillation appeared to be risk factors for incident stroke among very old people [34-37]. In the present study, SBP at least 160 mmHg was not associated with incident stroke in the univariate model, but was associated with higher mortality risk. We highlight the importance of BP management in patients with risk factors for intracerebral hemorrhage. Some of these factors may increase mortality risk, individually or collectively as a measure of geriatric multimorbidity. It is possible that mortality depends on other factors [38] such as hemorrhage size. Our study includes very old people with cognitive and/or physical disability, and whether hypertension truly increases stroke risk in representative populations of very old people remains unclear because the prevalence of SBP ≥ 160 mmHg is similar (12.0% vs. 11.2%, p 0.407) [39-41] in people with and without ADL dependence and cognitive impairment. Confounding factors may obscure the association between BP and incident stroke unless accounted for. However, women with cognitive impairment could be a target population for care interventions.

Researchers have arbitrarily chosen various cut-off points in the definition of polypharmacy. Therefore, an elderly patient with at least two disease states will usually exceed this arbitrary threshold. In total, 91.6% of CCP had ≥ 4 active medications, 52.4% between 4-9, and 32.9% ≥ 10. The average use of 9.0 daily medications by our study participants is consistent with the existing literature [42,43], but it is high and concerning. On the other hand, polypharmacy is not just the use of multiple medications, but also and/or the administration of more medications than are clinically indicated, representing unnecessary drug use [44,45]. In our study, the most used therapeutic groups are coincident with those commonly involved in inappropriate prescription: treatment of peptic ulcers, cardiovascular medications, antidepressants, and hypnotics [46]. Future research should document more evidence regarding the reality of rationing in CCP, adverse drugdrug interactions, and the increased risk of falling.

There is confusion over whether the risk of hemorrhagic stroke is increased in people taking statins. Several meta-analyses have shown either no increase, or a non-significant increase, in the risk of hemorrhagic stroke when statins are used for primary or secondary prevention [47,48]. Despite having similar rates of cardiovascular comorbidities, hemorrhagic patients who receive statins are significantly more likely to survive after stroke onset compared with non-users [4] and continuing statins after ICH may not only be safe but could also be beneficial [49]. In our study, statins were the second drug in terms of frequency of prescription in 46.4% of hemorrhagic patients. The decision to stop or continue [50] statin treatment in patients after hemorrhagic stroke remains controversial, and needs randomized trials investigating statin use in patients with acute intracerebral hemorrhage to inform patient management.

Eventually, the fragmented care contributes to the overall decline of elders living in any environment [51]. Coordination among clinicians and caregivers and the periodic critical review of all the medications taken, and establishing a close relationship with the family, primary care physician, and social workers are essential. After happening the intracerebral haemorrhage, an increase in favourable functional outcome rather than simple survive and the decisions about the direction of care could be influenced by the previous good care of these variables.

In the unadjusted analysis, the patients who had a previous ischemic stroke were at a significantly higher risk of death (Figure 3) if they had been registered as a fall risk. The fall risk was higher (31.9% vs. 19.2%, p 0.012) among those with hemorrhagic stroke, but without an impact on long-term survival. Routine clinical questioning about previous falls may, thus, be a key strategy to identify at-risk individuals so preventive interventions can be introduced.

The percentage of polypharmacy (≥ 10 active medications) was associated to higher mortality in the presence of a fall risk (Figure 4), but without a difference in the average Charlson score or prevalence of comorbidities. We also found a higher percentage of cases using SSRIs among those with a fall risk, but without difference (p 0.2211) in mortality risk. Isolation and loneliness have been shown to be a risk factor for falls. The percentage in our study was 22.3% among people ≥ 75 years old.
