Diagnoses indicating pain and analgesic drug prescription in patients with dementia: a comparison to age- and sex-matched controls

The interactive effects of different exercises and hawthorn consumption on the pain threshold of TMT-induced Alzheimer male rats

Exercise increases the pain threshold in healthy people. However, the pain threshold modulation effect of exercise and hawthorn is unclear because of its potential benefits in people with persistent pain, including those with Alzheimer's disease. Accordingly, after the induction of Alzheimer's disease by trimethyl chloride, male rats with Alzheimer's disease were subjected to a 12-week training regimen consisting of resistance training, swimming endurance exercises, and combined exercises. In addition, hawthorn extract was orally administered to the rats. Then, their pain threshold was evaluated using three Tail-flick, Hot-plate, and Formalin tests. Our results showed that Alzheimer's decreased the pain threshold in all three behavioral tests. Combined exercise with hawthorn consumption had the most statistically significant effect on Alzheimer's male rats' pain threshold in all three experiments. A combination of swimming endurance and resistance exercises with hawthorn consumption may modulate hyperalgesia in Alzheimer's rats. Future studies need to determine the effects of these factors on the treatment and/or management of painful conditions.

Partnering to cope with pain: A pilot study of a caregiver-assisted pain coping skills intervention for patients with cognitive impairment and dementia

OBJECTIVE

To develop a new caregiver-assisted pain coping skills training protocol specifically tailored for community-dwelling persons with cognitive impairment and pain, and assess its feasibility and acceptability.

METHOD

In Phase I, we conducted interviews with 10 patient-caregiver dyads to gather feedback about intervention content and delivery. Phase II was a single-arm pilot test to evaluate the intervention's feasibility and acceptability. Dyads in the pilot study (n = 11) completed baseline surveys, received five intervention sessions, and then completed post-intervention surveys. Analyses focused on feasibility and acceptability.

RESULTS

Dyads responded positively to the pain coping skills presented in the interviews; their feedback was used to refine the intervention. Findings from the pilot study suggested that the intervention was feasible and acceptable. 69% of eligible dyads consented, 82% completed all five intervention sessions, and 100% completed the post-treatment assessment. Caregivers reported high satisfaction ratings. They also reported using the pain coping skills on a regular basis, and that they found most of the skills helpful and easy to use.

SIGNIFICANCE OF RESULTS

These preliminary findings suggest that a caregiver-assisted pain coping skills intervention is feasible and acceptable, and that it may be a promising approach to managing pain in patients with cognitive impairment.

Pharmacological Pain Treatment in 2012 and 2017 Among Older People with Major Neurocognitive Disorder

Background and Objective

Pain is highly prevalent among older people, and treatment is complicated because of comorbidities and polypharmacy. Among people with major neurocognitive disorder additional difficulties might arise. The aim of this study was to describe analgesic drug use in 2012 and 2017 and associated factors among older people with major neurocognitive disorder.

Methods

In this register-based study, the Swedish Dementia Registry and the Swedish Prescribed Drug Register were combined in order to obtain data regarding analgesic drug use among older people with major neurocognitive disorder. One or more filled prescriptions during the timeframe of 6 months (1 July–31 December 2012 and 1 July–31 December 2017) defined drug use during the respective period. A comparison between 2012 and 2017 was made, including a total of 56,101 people (20,889 and 35,212 respectively) with a mean age of 81.9 and 82.7 years, respectively.

Results

The overall use of analgesic drugs increased significantly from 41.6% of individuals to 46.0% between the years 2012 and 2017. Users of opioid analgesics (15.2% vs 17.3%) and paracetamol (37.0% vs 42.3%) increased, while the users of non-steroidal anti-inflammatory drugs (4.9% vs 2.7%) declined between the two data collections. Multiple logistic regression analyses were performed for different drugs and drug classes, and it was found that the use of opioids and paracetamol was associated with older age and a longer time since diagnosis. In contrast, non-steroidal anti-inflammatory drugs were associated with younger age and a shorter time since diagnosis.

Conclusions

The results indicate that on a population level, pharmacological drug treatment has changed in line with guidelines between 2012 and 2017, with an increase in paracetamol and strong opioids and a decrease in non-steroidal anti-inflammatory drugs and tramadol. The relatively high prevalence of opioids warrants concern given the significant risk of adverse effects among older people with major neurocognitive disorder.

Prescription of analgesics in patients with rheumatic diseases in Germany : A claims data analysis

Objective

To investigate the prescription frequency of analgesics in persons diagnosed with rheumatoid arthritis (RA), axial spondylarthritis (axSpA), psoriatic arthritis (PsA) and systemic lupus erythematosus (SLE) in 2019 using claims data.

Methods

Persons ≥ 18 years insured in 2019 with a diagnosis of RA (M05, M06), axSpA (M45), PsA (M07.0-3) or SLE (M32.1,8,9) were included. Analgesics were identified by the anatomic therapeutic classification (ATC) system. Reported is the percentage of individuals with ≥ 1 analgesics prescription for the respective rheumatic diagnosis in 2019 and for opioids age-standardized in each of the years 2005–2019. In addition, the proportion of long-term opioid use (prescriptions in ≥ 3 consecutive quarter years) in 2006 and 2019 is compared.

Results

Metamizole (29–33%) was the most commonly prescribed analgesic. Nonsteroidal anti-inflammatory drugs (NSAID)/coxibs were prescribed from 35% (SLE) to 50% (axSpA). Of the patients 11–13% were prescribed weak and 6–8% strong opioids. From 2005 to 2019, the proportion of persons with an opioid prescription remained stable, with similar or slightly decreasing proportions of weak opioids and more frequent prescriptions of strong opioids. The proportion of long-term opioid prescriptions increased from 2006 to 2019 from 8.9% to 11.0% (RA), from 6.9% to 9.1% (axSPA), from 7.8% to 9.5% (PsA), and from 7.5% to 8.8% (SLE), corresponding to a 17–24% increase.

Conclusion

The prescription of opioids for persons with inflammatory rheumatic diagnoses is not as high in Germany as in other countries; however, the proportion of long-term prescriptions has considerably increased. The frequent prescription of metamizole is conspicuous.

CONCLUSION

The prescription of opioids for persons with inflammatory rheumatic diagnoses is not as high in Germany as in other countries; however, the proportion of long-term prescriptions has considerably increased. The frequent prescription of metamizole is conspicuous.

Prevalence of Pain on Admission by Level of Cognitive Impairment in Nursing Homes

PURPOSE

To provide contemporary estimates of pain by level of cognitive impairment among US nursing home residents without cancer.

METHODS

Newly admitted US nursing home residents without cancer assessed with the Minimum Data Set 3.0 at admission (2010-2016) were eligible (n=8,613,080). The Cognitive Function Scale was used to categorize level of cognitive impairment. Self-report or staff-assessed pain was used based on a 5-day look-back period. Estimates of adjusted prevalence ratios (aPR) were derived from modified Poisson models.

RESULTS

Documented prevalence of pain decreased with increased levels of cognitive impairment in those who self-reported pain (68.9% no/mild, 32.9% severe) and those with staff-assessed pain (50.6% no/mild, 37.2% severe staff-assessed pain). Relative to residents with no/mild cognitive impairment, pharmacologic pain management was less prevalent in those with severe cognitive impairment (self-reported: 51.3% severe vs 76.9% in those with no/mild; staff assessed: 52.0% severe vs 67.7% no/mild).

CONCLUSION

Pain was less frequently documented in those with severe cognitive impairment relative to those with no/mild impairments. Failure to identify pain may result in untreated or undertreated pain. Interventions to improve evaluation of pain in nursing home residents with cognitive impairment are needed.

[Hospitalization of nursing home residents in the last phase of life: an analysis of health insurance data]

Hintergrund

Im internationalen Vergleich versterben Pflegeheimbewohner in Deutschland häufig im Krankenhaus. Daten zu längeren Zeiträumen vor dem Tod und zu regionalen Unterschieden fehlen.

Ziel der Arbeit

Es werden Häufigkeiten von Krankenhausaufenthalten bei Pflegeheimbewohnern in verschiedenen Perioden vor dem Tod analysiert. Zudem werden Unterschiede nach Alter, Geschlecht, Pflegestufe, Demenz und Bundesländern untersucht.

Material und Methoden

Wir verwendeten Daten einer großen Krankenkasse und schlossen Pflegeheimbewohner im Mindestalter von 65 Jahren ein, die zwischen dem 01.01.2010 und dem 31. 12.2014 verstarben. Outcome war mindestens ein Krankenhausaufenthalt nach Heimeintritt in verschiedenen Phasen des letzten Lebensjahres. Vertiefende Analysen wurden für die Zeiträume 0 (entspricht Versterben im Krankenhaus), 28 und 365 Tage vor Tod durchgeführt.

Ergebnisse

Von den insgesamt 67.328 verstorbenen Bewohnern (mittleres Alter: 85,3 Jahre; 69,8 % weiblich), verstarben 29,5 % im Krankenhaus. In den letzten 28 bzw. 365 Tagen vor Tod hatten 51,5 % bzw. 74,3 % mindestens einen Krankenhausaufenthalt. Diese Werte waren in ostdeutschen Bundesländern höher. In allen Zeiträumen wurden Männer häufiger hospitalisiert. Bewohner mit höherer Pflegestufe wurden seltener stationär behandelt, besonders unmittelbar vor dem Tod. Demenz hatte keinen nennenswerten Einfluss auf die Hospitalisierungshäufigkeiten.

Diskussion

Etwa die Hälfte der Pflegeheimbewohner wird im letzten Lebensmonat stationär behandelt, und ein Drittel verstirbt im Krankenhaus, was, international betrachtet, hoch ist. Dass wir keine Unterschiede bei Bewohnern mit und ohne Demenz fanden, widerspricht ebenso internationalen Befunden. Somit besteht erheblicher Handlungsbedarf, die palliative Versorgung von Pflegeheimbewohnern zu optimieren.

Ten-year trends in end-of-life hospitalizations of nursing home residents in Germany, 2006-2015

OBJECTIVES

We investigated trends in end-of-life hospitalizations among nursing home residents (NHR) over 10 years and looked at differences between age groups and sexes as well as the length of terminal hospital stays.

STUDY DESIGN

Retrospective cohort study based on health insurance claims data of the AOK Bremen/Bremerhaven. All NHR aged 65 years or more who died between 2006 and 2015 were included.

MAIN OUTCOME MEASURES

We assessed the proportions of decedents who were in hospital on the day of death and during the last 3, 7, 14 and 30 days of life, stratified by two-year periods. Multiple logistic regressions were conducted to study changes over time, adjusting for covariates.

RESULTS

A total of 10,781 decedents were included (mean age 86.1 years, 72.1 % females). Overall, 29.2 % died in hospital, with a slight decrease from 30.3 % in 2006-2007 to 28.3 % in 2014-2015 (OR 0.86; 95 % CI 0.75-0.98). Of the 3150 terminal hospitalizations, 35.5 % lasted up to 3 days and the mean length of stay decreased from 9.0 (2006-2007) to 7.5 days (2014-2015). When looking at the last 7, 14 and 30 days of life, no changes over time were found. Male sex and younger age were associated with a higher chance of end-of-life hospitalization in almost all analyses.

CONCLUSIONS

End-of-life hospitalizations of NHR are common in Germany. There has been a small decrease during recent years in the proportion of in-hospital deaths, but not of hospitalizations during the last 7, 14 and 30 days of life. This might be explained by shorter durations of hospital stays.

Primary diagnoses and outcomes of emergency department visits in older people with dementia: a hospital-based retrospective study in Taiwan

OBJECTIVES

The objectives of this study were to investigate the primary diagnoses and outcomes of emergency department visits in older people with dementia and to compare these parameters with those in older adults without dementia.

DESIGN AND SETTING

This hospital-based retrospective study retrieved patient records from a hospital research database, which included the outpatient and inpatient claims of two hospitals.

PARTICIPANTS

The patient records were retrieved from the two hospitals in an urban setting. The inclusion criteria were all patients aged 65 and older who had attended the two hospitals as an outpatient or inpatient between January 1, 2009, and December 31, 2016. Patients with dementia were identified to have at least three reports of diagnostic codes, either during outpatient visits, during emergency department visits, or in hospitalized database records. The other patients were categorized as patients without dementia.

MEASUREMENTS

The primary diagnosis during the emergency department visit, cost of emergency department treatment, cost of hospital admission, length of hospital stay, and diagnosis of death were collected.

RESULTS

A total of 149,203 outpatients and inpatients aged 65 and older who were admitted to the two hospitals were retrieved. The rate of emergency department visits in patients with dementia (23.2%) was lower than that in those without dementia (48.6%). The most frequent primary reason for emergency department visits and the main cause of patient death was pneumonia. Patients with dementia in the emergency department had higher hospital admission rates and longer hospital stays; however, the cost of treatment did not show a significant difference between the two groups.

CONCLUSIONS

Future large and prospective studies should explore the severity of disease in older people with dementia and compare results with older adults without dementia in the emergency department.

Dying in hospital among nursing home residents with and without dementia in Germany

OBJECTIVES

Nursing home residents (NHR) often suffer from dementia. As end-of-life care of NHR with dementia and without might differ, our aim was to investigate patterns of in-hospital deaths in NHR with and without dementia.

DESIGN

Retrospective observational study.

SETTING

German nursing homes.

PARTICIPANTS

Deceased NHR.

MEASUREMENTS

Using data of a large German health insurance fund, we included NHR aged 65+ years who died between January 1, 2010, and December 31, 2014. We assessed proportions of in-hospital deaths stratified by dementia status as well as by age, sex, level of care and length of stay. Multiple logistic regression models were applied to explore the association of these variables with in-hospital death.

RESULTS

Data on 67,328 decedents were included (mean age 85.3 years, 69.8% female), of whom 43.1% suffered from dementia. Overall, 29.5% died in hospital, with similar figures found for those with dementia (29.2%) and those without (29.8%). Differences between NHR with and without dementia were noticeable regarding age and length of stay. In those with dementia, the proportion of in-hospital deaths decreased linearly with age from 37.0%-20.2% (65-74 to 95+ years). These results are supported by the multivariate analyses. The terminal hospital stay was up to 3 days in 32.6%. This length did not differ by dementia status.

CONCLUSIONS

Germany has a high proportion of NHR in-hospital deaths. Surprisingly, we found no differences in these figures between NHR with and without dementia, although predictors for in-hospital death seem to differ between these groups.

Opioid use and the presence of Alzheimer's disease and related dementias among elderly Medicare beneficiaries diagnosed with chronic pain conditions

Introduction

There is scant literature on the use of opioids among community-dwelling elderly with Alzheimer's disease and related dementias (ADRD).

Methods

We adopted a retrospective, cross-sectional study design using Medicare Current Beneficiary Survey data from 2006 to 2013. The study sample included elderly community-dwelling Medicare beneficiaries who were diagnosed with chronic pain conditions and had Medicare fee-for-service plans for the entire year. We conducted bivariate χ² test and multivariate logistic regression to examine the relationship between opioid use and ADRD status.

Results

The study sample included 19,347 Medicare beneficiaries; 7.7% of them had ADRD. We found no statistically significant difference in opioid use by ADRD status in the unadjusted analysis; however, controlling for various factors, those with ADRD had lower odds of opioid use (adjusted odds ratio = 0.81, 95% confidence interval = 0.71, 0.93) than those without ADRD.

Discussion

This population-based study suggests that elderly Medicare beneficiaries with ADRD and chronic pain conditions may have undertreatment of pain.

Prevalence and treatment of hip and knee osteoarthritis in people aged 60 years or older in Germany: an analysis based on health insurance claims data

Objective

Osteoarthritis (OA) is highly prevalent throughout the world, especially in the elderly population, and is strongly associated with patients’ frailty. However, little is known about the prevalence and treatment of OA in elderly patients in routine clinical care in Germany.

Materials and methods

As a part of Linking Patient-Reported Outcomes with CLAIms Data for Health Services Research in Rheumatology (PROCLAIR), a cross-sectional study using claims data from a large Germany statutory health insurance (BARMER) was conducted. We included people aged 60 years or older and assessed the prevalence of OA of the hip or knee, defined as having outpatient diagnoses (ICD: M16 or M17) in at least two quarters of 2014. The use of conservative treatment, including analgesics and physical therapy, and total joint replacement was studied. Analyses were stratified by age, sex, comorbidities, and level of care dependency defined by social law.

Results

A total of 595,754 patients (mean age: 74.9 years; 69.8% female) were diagnosed with OA (21.8%), with the highest prevalence in those between 80 and 89 years (31.0%) and in females compared to males (23.9% vs 18.3%). Prevalence decreased with increasing level of care dependency from 30.5% in patients with a low level (0/1) to 18.7% in the highest level of care dependency. A total of 63.4% of the patients with OA received analgesics, with higher use with increasing age. Physical therapy was prescribed to 43.1% of the patients, but use decreased with age. In all, 5.3% of the patients received total joint replacement in 2014.

Conclusion

The lower frequency of coded OA with increasing level of care dependency may reflect underdiagnosis, and patients with many other medical problems seem to be at risk for inadequate recognition and treatment of their OA.

Prevalence of pain-related diagnoses in patients with dementia: a nationwide study

Purposes

To investigate the prevalence of pain-related diagnoses in patients with dementia and evaluate the association of pain-related diagnoses with demographic characteristics and dementia subtypes.

Patients and methods

In this population-based retrospective cohort study, participants were recruited from a cohort of 2 million people randomly sampled from the general population in the National Health Insurance Research Database of Taiwan from 2000 to 2013. The index year was defined as the period of 1 year from the date of the first diagnosis of dementia.

Results

The study group comprised 28,450 patients with the dementia subtypes of vascular dementia, Alzheimer’s disease, or other dementia subtypes. The mean age of patients with dementia was 76.75 years. Of all patients with dementia, 49.07% had at least one pain-related diagnosis documented in their outpatient or inpatient claim records within the index year. The top three pain-related diagnoses were osteoarthritis (29.27%), headache (12.53%), and osteoporosis (11.43%). Musculoskeletal diagnosis was more likely in female patients with vascular dementia. Although patients with vascular dementia had a significantly lower prevalence of pain-related diagnosis, they had a significantly higher risk of 1-year mortality than patients with other dementia subtypes.

Conclusion

During the index year, 49.07% of patients with dementia had at least one pain-related diagnosis. To investigate the differences of the use of pain medication in patients with different dementia subtypes and the difference of pain-related diagnosis and treatment in patients with and without dementia, future studies are recommended.

Perioperative neurocognition in elderly patients

PURPOSE OF REVIEW

The extrinsic risk factors for postoperative cognitive disturbance have been a source of concern during the perioperative period, and these risk factors remain the subject of controversy. This review of recent studies focuses on the effect of these factors on postoperative cognitive disturbance during the perioperative period.

RECENT FINDINGS

Impairment of cerebral autoregulation may predispose patients to intraoperative cerebral malperfusion, which may subsequently induce postoperative cognitive disturbance. The neurotoxicity of several volatile anesthetics may contribute to cognitive functional decline, and the impact of intravenous anesthesia on cognitive function requires further exploration. Multimodal analgesia may not outperform traditional postoperative analgesia in preventing postoperative delirium. Furthermore, acute pain and chronic pain may exacerbate the cognitive functional decline of patients with preexisting cognitive impairment. The nuclear factor-kappa beta pathway is an important node in the neuroinflammatory network.

SUMMARY

Several intraoperative factors are associated with postoperative cognitive disturbance. However, if these factors are optimized in perioperative management, postoperative cognitive disturbance will improve.

Oral health and orofacial pain in people with dementia admitted to acute hospital wards: observational cohort study

Background

Orofacial pain in people with dementia is difficult to detect, and often under-treated. Our aim was to investigate the prevalence of orofacial pain in people with dementia in acute hospitals in the UK. Secondary aims were to examine oral health status and explore associations between orofacial pain and oral health factors.

Methods

This cross-sectional observational study was carried out in two UK hospitals. Using the Orofacial Pain Scale in Non-Verbal Individuals (OPS-NVI) to identify orofacial pain, 101 participants with dementia, admitted to acute medical wards, were observed for at least 3 min during rest and chewing. Verbal participants were then asked about presence of orofacial pain, using self-report pain scales. Finally, a brief oral assessment was performed.

Results

Orofacial pain, assessed with the OPS-NVI, was present in 11.9% (95% C.I. 5.9, 18.8) of participants at rest and 21.9% (95% C.I. 14.6, 31.3) whilst chewing. Participants who were no longer able to self-report pain were significantly more likely to experience orofacial pain. Oral health in both dentate and edentate participants was poor. Brush frequency, indication of chewing quality, consistency of the food, presence of extra-oral abnormalities, person who performed mouth care, and oral hygiene in dentate participants were significant predictors for the presence of orofacial pain.

Conclusion

Improving oral care in acute hospital patients with dementia, particularly those who cannot self-report pain, may significantly reduce pain and suffering in this population.

Variations over time in the effects of age and sex on hospitalization rates before and after admission to a nursing home: A German cohort study

OBJECTIVES

We examined hospitalization rates for nursing home residents before and after their entry to the home, stratified by sex and age.

STUDY DESIGN

A cohort study was conducted using data from a large health insurance fund on 127,227 residents aged 65 years and over newly admitted to a nursing home between January 1, 2010, and December 31, 2014.

MAIN OUTCOME MEASUREMENTS

We assessed hospitalization rates and proportions being hospitalized in 6-month intervals one year before nursing home placement and up to 5 years thereafter. Multiple Poisson regression models were fitted to calculate relative risks (RR).

RESULTS

Mean age was 84.0 years and 74.6% of the cohort were females. Hospitalization rates were 194.4 per 100 person-years (PY) in the 12 months before entry to the nursing home and 120.0 per 100 PY thereafter. Rates were highest immediately before entry in both sexes. The influence of age was most pronounced in the 12-7 months before entry (RR: 2.37 for 65-74 vs. 95+ years) and declined thereafter (1.29-1.38 up to month 24 after entry). In contrast, the influence of sex was greater after entry (RR: 1.13 for males vs. females in the 12-7 months before and 1.23-1.31 up to month 24 after entry).

CONCLUSIONS

Hospitalization rates of nursing home residents are much higher in Germany than in other Western countries. We have provided some insight into the influence of age and sex on hospitalization rates, which varied over the period (time before and after entry to the nursing home) analyzed. We urgently recommend that future studies on the hospitalization of residents stratify their analyses by sex, age and period.

[Pain medication in nursing home residents with and without cancer. Most frequently with metamizole]

BACKGROUND

Pain is a highly prevalent symptom in nursing home residents. The analgesic pharmacotherapy of older adults is associated with challenges; however, studies from Germany examining the prescription pattern of analgesics in nursing home residents are rare.

OBJECTIVES

This study was carried out to examine the prescription of analgesics in nursing home residents with and without the diagnosis of cancer.

MATERIAL AND METHODS

Using health insurance claims data persons aged ≥ 65 years who were newly admitted to a nursing home between 2004 and 2009 and who survived at least the first 90 days after admission were included in the study. Cancer was identified by outpatient diagnoses of malignant neoplasms (ICD-10: C00-C97). Prescription drugs within the first 90 days after admission to a nursing home were analyzed which means that aspirin and acetaminophen were not taken into account.

RESULTS

A total of 5549 nursing home residents were included, who were on average 81.5 years old (56.8 % females). More than half (53.5 %) were assigned to care level I and 781 (14.1 %) were diagnosed with cancer. The study cohort received on average 7.8 different medications (with vs. without cancer: 8.6 vs. 7.6, respectively) and 43.8 % had prescriptions for analgesics (with vs. without cancer: 52.5 vs. 42.3 %, respectively). A total of 37.1 % were taking WHO step 1 analgesics (step 2: 11.4 % and step 3: 9.2 %). The proportion of persons receiving metamizole (dipyrone) was 28.3 % (with vs. without cancer: 35.6 vs. 27.1 %, respectively). Regarding all prescriptions, metamizole was by far the most frequently prescribed medication in nursing homes followed by melperone and omeprazole.

CONCLUSION

Approximately one third of nursing home residents received metamizole and most were long-term prescriptions. Considering that metamizole is associated with potentially life-threatening adverse effects, caution is indicated particularly when prescribed over long periods.

Influence of age and sex on hospitalization of nursing home residents: A cross-sectional study from Germany

Background

Nursing homes residents (NHR) are frequently transferred to hospitals. There is some evidence that male NHR are more often hospitalized than females, but the influence of age is less clear and predictors might differ between sexes. Analyses according to age groups between males and females have only been investigated once and none of the existing studies have conducted multivariate analyses stratified by sex. Aim of this study was to fill this gap.

Methods

We used data of the “Inappropriate Medication in patients with REnal insufficiency in Nursing homes” (IMREN) study, which was conducted between October 2014 and April 2015 in nursing homes in northwestern Germany (Bremen and Lower Saxony). Anonymised data was obtained by nursing staff of the participating nursing homes. All residents living in the participating care units were included. We assessed whether they were hospitalized at least once during the preceding 12 months. Cluster-adjusted multivariate logistic regression was applied to identify variables associated with hospitalizations. All analyses were stratified by sex.

Results

Of 852 residents from 21 nursing homes (mean age 83.5 years; 76.5% females), 43.1% (95% confidence intervals [95% CI]: 35.6–50.5) were hospitalized at least once during the preceding 12 months. This proportion was higher in residents institutionalized within the last 6 months compared to those with a longer length of stay (65.7% vs. 39.5%). Although not statistically significant, males were more often hospitalized than females (52.4% vs. 40.3%) and differences between sexes are particularly remarkable for age, health status and length of stay. In females, the chance of being hospitalized decreased steadily with age (OR: 2.40 [95% CI: 1.24–4.64] and 1.60 [95% CI: 1.05–2.43] for age groups <75 and 75–84 years compared to 85+ years). On the other hand, males aged 75–84 years had a statistically significant lower chance compared to 85+ years olds (OR: 0.41; 95% CI: 0.19–0.90).

Conclusions

Differences in factors associated with hospitalizations might exist between sexes. We strongly suggest that further studies on hospitalizations of NHR should stratify their analyses by sex.

Polypharmacy and inappropriate medication use in patients with dementia: an underresearched problem

Multimorbidity and polypharmacy are increasingly prevalent across healthcare systems and settings as global demographic trends shift towards increased proportions of older people in populations. Numerous studies have demonstrated an association between polypharmacy and potentially inappropriate prescribing (PIP), and have reported high prevalence of PIP across settings of care in Europe and North America and, as a consequence, increased risk of adverse drug reactions, healthcare utilization, morbidity and mortality. These studies have not focused specifically on people with dementia, despite the high risk of adverse drug reactions and PIP in this patient cohort. This narrative review considers the evidence currently available in the area, including studies examining prevalence of PIP in older people with dementia, how appropriateness of prescribing is assessed, the medications most commonly implicated, the clinical consequences, and research priorities to optimize prescribing for this vulnerable patient group. Although there has been a considerable research effort to develop criteria to assess medication appropriateness in older people in recent years, the majority of tools do not focus on people with dementia. Of the limited number of tools available, most focus on the advanced stages of dementia in which life expectancy is limited. The development of tools to assess medication appropriateness in people with mild to moderate dementia or across the full spectrum of disease severity represents an important gap in the research literature and is beginning to attract research interest, with recent studies considering the medication regimen as a whole, or misprescribing, overprescribing or underprescribing of certain medications/medication classes, including anticholinergics, psychotropics, antibiotics and analgesics. Further work is required in development and validation of criteria to assess prescribing appropriateness in this vulnerable patient population, to determine prevalence of PIP in large cohorts of people with the full spectrum of dementia variants and severities, and to examine the impact of PIP on health outcomes.

The landscape of pain management in people with dementia living in care homes: a mixed methods study

OBJECTIVES

The aim of this study is to explore the current landscape of pain management in people with dementia living in care home settings. Pain is extremely common in this patient group, yet there is very limited guidance for healthcare professionals.

METHODS

Triangulation of stakeholder consultation and quality review of pain management guidance were performed. A review of existing pain management guidance was conducted using published quality criteria adapted for the field. Three focus group discussions were held with care home staff and two focus group discussions and an online survey with family carers. Data were subjected to thematic analysis to identify themes and sub-themes. Outcomes were reviewed by an expert panel, which gave recommendations.

RESULTS

Fifteen existing guidelines were identified, of which three were designed for use in dementia and none were tailored for care home settings. Thematic analysis revealed six major themes in current pain management in dementia: importance of person-centredness, current lack of pain awareness in staff, communication as a core element, disparities in staff responsibility and confidence, the need for consistency of care and current lack of staff training. In addition to the needs for practice, the expert panel identified promising pharmacological treatment candidates, which warrant clinical evaluation.

CONCLUSIONS

The findings of this study clearly articulate a need for an evidence-based pain management programme for care homes, which is informed by stakeholder input and based within a conceptual framework for this setting. There are novel opportunities for clinical trials of alternative analgesics for use in this patient group. Copyright © 2016 John Wiley & Sons, Ltd.

Differences in analgesic use in community-dwelling persons with and without Alzheimer's disease

BACKGROUND

There are conflicting findings about analgesic use among persons with cognitive impairment compared to cognitively intact older persons. The objective of our study was to investigate the prevalence of analgesic use in community-dwelling persons with and without Alzheimer's disease (AD), within six months after AD diagnosis and to find out factors associated with the use of analgesics and specific analgesic groups.

METHOD

We utilized data from register based MEDALZ (Medication use and Alzheimer's disease) cohort consisting of all community-dwelling persons diagnosed with AD during 2005-2011 in Finland and their matched comparison persons without AD. Altogether, 67,215 persons with AD and one comparison person for each case were included. Drug use data were collected from the Prescription Register and comorbidities from Special Reimbursement and Hospital Discharge Registers.

RESULTS

Statistically significant (p < 0.001) yet mostly small differences were found for analgesics use: analgesics were used by 34.9% and 33.5% of persons with and without AD, respectively. Paracetamol was the most frequently used analgesic both among persons with (25.0%) and without AD (19.1%). Persons with AD used less frequently NSAIDs (Nonsteroidal Anti-inflammatory Drugs) (13.2% vs. 17.3%) and mild opioids (5.0% vs. 7.1%), while the use of strong opioids was more common in comparison to persons without AD (1.3% vs. 1.1%, respectively). Analgesic users were more likely women, aged ≥80 years, had asthma/COPD, cardiovascular disease, diabetes, cancer, hip fracture, osteoporosis, rheumatoid arthritis, and lower socioeconomic position.

CONCLUSION

Further studies are needed to evaluate the adequateness of pain relief in older persons with and without AD.

SIGNIFICANCE

Persons with Alzheimer's disease (AD) used more frequently paracetamol and less frequently NSAIDs and mild opioids. A decreasing trend of NSAID use was observed among persons with AD during the study period.

The assessment and management of pain in patients with dementia in hospital settings: a multi-case exploratory study from a decision making perspective

BACKGROUND

Pain is often poorly managed in people who have a dementia. Little is known about how this patient population is managed in hospital, with research to date focused mainly on care homes. This study aimed to investigate how pain is recognised, assessed and managed in patients with dementia in a range of acute hospital wards, to inform the development of a decision support tool to improve pain management for this group.

METHODS

A qualitative, multi-site exploratory case study. Data were collected in four hospitals in England and Scotland. Methods included non-participant observations, audits of patient records, semi-structured interviews with staff and carers, and analysis of hospital ward documents. Thematic analysis was performed through the lens of decision making theory.

RESULTS

Staff generally relied on patients' self-report of pain. For patients with dementia, however, communication difficulties experienced because of their condition, the organisational context, and time frames of staff interactions, hindered patients' ability to provide staff with information about their pain experience. This potentially undermined the trials of medications used to provide pain relief to each patient and assessments of their responses to these treatments. Furthermore, given the multidisciplinary environment, a patient's communication about their pain involved several members of staff, each having to make sense of the patient's pain as in an 'overall picture'. Information about patients' pain, elicited in different ways, at different times and by different health care staff, was fragmented in paper-based documentation. Re-assembling the pieces to form a 'patient specific picture of the pain' required collective staff memory, 'mental computation' and time.

CONCLUSIONS

There is a need for an efficient method of eliciting and centralizing all pain-related information for patients with dementia, which is distributed in time and between personnel. Such a method should give an overall picture of a patient's pain which is rapidly accessible to all involved in their care. This would provide a much-needed basis for making decisions to support the effective management of the pain of older people with dementia in hospital.

Pain treatment for nursing home residents differs according to cognitive state - a cross-sectional study

Background

Communication skills are known to decrease with advancing cognitive impairment. Analgesic treatment in long-term care may be deficient due to the residents’ impaired ability to communicate their pain and needs. Undertreated pain frequently leads to rising BPSD in residents with cognitive impairment, resulting in a treatment with antipsychotics. Aim of this study was the analysis of differences in assessment and pharmacological treatment of pain in nursing home residents relative to their cognitive state and ability to articulate pain.

Methods

Data stems from the baseline of a non-experimental pre-post-study in 12 Austrian nursing homes. Residents’ pain prevalence in relation to pain assessment and cognitive decline was assessed, data on medical diagnoses and prescriptions were retrieved from the nursing homes’ documentation (n = 425). Residents were first divided into two groups: Residents with MMSE ≥ 18 were selected into group CUS (cognitively unimpaired/slightly impaired), residents with MMSE ≤ 17 were selected into group CI (cognitively moderately to severely impaired). CI residents were then sub-grouped according to their ability to communicate pain via the Verbal Rating Scale (VRS) (i.e. group CI-V, group CI-NV). Pain behavior of CI residents was assessed with a modified German version of PAINAD. Group differences were tested with ANOVA and H-test, 95 % confidence intervals were calculated and associations were tested with log-binomial regression.

Results

Pain prevalence in CI residents irrespective of their ability to communicate pain was 80 % and exceeded the CUS group prevalence significantly by 14 %. CI residents had significantly less analgesic prescriptions. Furthermore, CI residents have a significantly higher risk of getting no analgesics when in pain than CUS residents (CI-V: RR =2.6, CI-NV: RR =3.4). Use of antipsychotics was high in all groups (49 – 65 %) with more prescriptions in the cognitively impaired group.

Conclusion

Results point toward an underuse of pain medication in cognitively impaired residents, especially those unable to communicate pain verbally. The implementation of standardized pain assessments adapted to the cognitive abilities of residents may foster the recognition of pain, warrant optimized pain management, reduce inadequate medication and consequently raise the chance of equally effective pain treatment regardless of cognitive state.

Identification, assessment, and management of pain in patients with advanced dementia

Patients with advanced dementia have a high symptom burden at end of life. Many of those with dementia have reports of symptoms similar to those without dementia, yet are treated less frequently. Pain is a prevalent symptom that can be underrecognized because of the ability of the patient to self-report. Several tools are available to help with the identification of pain, but they should only be one aspect in the overall assessment. Health care providers must anticipate this and screen for and treat potential pain. This includes obtaining a self-report, searching for potential causes for pain, observing patient behavior, gaining proxy reporting of pain, and attempting an appropriate analgesic trial. It is beneficial for all those involved with a patient's care to screen for pain because of the potential benefits in decreasing behaviors and subsequent antipsychotic use.

Pain medication in German nursing homes: a whole lot of metamizole

PURPOSE

Prescribing of metamizole (dipyrone), an analgesic that has been withdrawn from the market or never approved in many countries owing to safety concerns, is high in elder persons in Germany. This study assessed the use of pain medications in German nursing homes with a special focus on prescribing patterns of metamizole.

METHODS

Using data of the 'Inappropriate Medication in Patients with Renal Insufficiency in Nursing Homes' (IMREN) study conducted between October 2014 and April 2015 in nursing homes in Bremen and Lower Saxony, we studied prescribing of analgesics including both scheduled and as-needed medications. For residents with scheduled medication, dosage and duration of use were analysed.

RESULTS

A total of 852 residents from 21 nursing homes were included. They were on average 83.5 years old, and 76.5% were women; 73.8% received at least one analgesic with 70.3% obtaining World Health Organization step I drugs. The most frequently prescribed substances were metamizole (for 40.6%) and paracetamol (acetaminophen; 35.6%), with paracetamol given mostly as-needed. The proportion of residents receiving metamizole increased with age (up to 47.4% in persons aged 90 years and over). Of 143 residents with scheduled metamizole (16.8%), the mean daily dosage was 1843 mg (interquartile range [IQR]: 1500-2250); 66.9% received metamizole for at least 90 days and 23.2% for at least 365 days (mean duration 276 days; IQR: 59-314).

DISCUSSION

There is a discrepancy between prescribing of metamizole for older persons, on the one hand, and evidence on comparative effectiveness and safety as well as approval and recommendations, on the other hand. Copyright © 2016 John Wiley & Sons, Ltd.

Who gets dipyrone (metamizole) in Germany? Prescribing by age, sex and region

WHAT IS KNOWN AND OBJECTIVE

Metamizole (dipyrone) is an analgesic that has been the focus of considerable controversy regarding its safety. Because of potentially life-threatening blood disorders such as agranulocytosis, it has been withdrawn in many countries but not in Germany, where prescribing even increased over recent years. We aimed to evaluate prescribing of metamizole in Germany with respect to age, sex and regional variations.

METHODS

Using data of a statutory health insurance, we analysed a cohort of 1·7 million persons who were insured at least 1 day in each quarter of 2009. Outcome of interest was the outpatient prescription prevalence, for example the proportion of persons receiving at least one prescription of metamizole.

RESULTS AND DISCUSSION

A total of 6·8% received metamizole with a higher prescribing prevalence in females (7·8% vs. 6·0%). The prevalence increased with age up to 26·7% in persons ≥85 years (men: 21·1%; and women: 30·4%). We found large regional variations with higher prevalences in the northern part of Germany. Most of the prescriptions were issued by general practitioners (78·9%). 58·3% were liquid oral formulations with considerable regional variations ranging between 32·3% in Mecklenburg-West Pomerania and 67·3% in North Rhine-Westphalia. Overall, liquid oral forms are much more often prescribed in the western than in the eastern part of Germany.

WHAT IS NEW AND CONCLUSION

Metamizole - a drug with a relatively narrow indication - is often prescribed in Germany with relevant differences by age, sex and region. Qualitative studies should clarify reasons for this. Further quantitative research should investigate small-area variations, indications and treatment durations.

Depressive symptoms are associated with analgesic use in people with Alzheimer's disease: Kuopio ALSOVA study

Neuropsychiatric symptoms of Alzheimer's disease (AD) such as depression may be associated with pain, which according to the literature may be inadequately recognized and managed in this population. This study aimed to identify the factors associated with analgesic use in persons with AD; in particular, how AD severity, functional status, neuropsychiatric symptoms of AD, co-morbidities and somatic symptoms are associated with analgesic use. 236 community-dwelling persons with very mild or mild AD at baseline, and their caregivers, were interviewed over five years as part of the prospective ALSOVA study. Generalized Estimating Equations (GEEs) were used to estimate unadjusted and adjusted odds ratios (ORs) for the factors associated with analgesic use over a five year follow-up. The proportion of persons with AD using any analgesic was low (13.6%) at baseline and remained relatively constant during the follow-up (15.3% at Year 5). Over time, the most prevalent analgesic changed from non-steroidal anti-inflammatories (8.1% of persons with AD at Year 1) to acetaminophen (11.1% at Year 5). Depressive symptoms (measured by the Beck Depression Inventory, BDI) were independently associated with analgesic use, after effects of age, gender, education, AD severity, comorbidities and somatic symptoms were taken into account. For every one unit increase in BDI, the odds of analgesic use increased by 4% (OR = 1.04, 95% confidence interval CI = 1.02-1.07). Caregiver depressive symptoms were not statistically significantly associated with analgesic use of the person with AD. Depressive symptoms were significantly associated with analgesic use during the five year follow-up period. Possible explanations warranting investigation are that persons with AD may express depressive symptoms as painful somatic complaints, or untreated pain may cause depressive symptoms. Greater awareness of the association between depressive symptoms and analgesic use may lead to safer and more effective prescribing for these conditions.
