The diagnostic value of the numeric pain rating scale in older postoperative patients

Effects of the WHO analgesic ladder on pain severity, pain interference, and blood pressure control in hypertensive patients with chronic musculoskeletal pain: a cross-sectional study

AIM

This study aimed to investigate the effects of pain management according to the World Health Organization (WHO) analgesic ladder on pain severity, pain interference, and blood pressure (BP) in treated hypertensive patients with chronic musculoskeletal pain.

BACKGROUND

Pain management can affect BP control owing to the proposed mechanism by which persistent pain contributes to increased BP. However, there are inadequate studies investigating the benefit of pain management in controlling both pain and BP in hypertensive patients who have chronic pain.

METHODS

In this cross-sectional study, demographic data and pain characteristics (resting pain score on the numerical pain rating scale, pain severity, and pain interference subscale of the Brief Pain Inventory) were collected via face-to-face interviews. BP was measured thrice on the same day. Data on pain medications taken in the previous 1 month were retrieved from the medical records. Participants were categorized into three groups following pain management patterns according to the WHO analgesic ladder: no, partial, and complete treatment. Multivariate logistic regression analysis (MLRA) was used to analyse the association between the variables and uncontrolled BP.

FINDINGS

Among 210 participants, the mean (standard deviation) age was 68 (15.5) years, and 60.47% had uncontrolled BP. The resting pain score, pain severity, and pain interference subscale scores of the complete treatment group were significantly lower than that of the partial treatment group (P = 0.036, 0.026, and 0.044, respectively). The MLRA revealed that pain management patterns were associated with uncontrolled BP (adjusted odds ratio [AOR]: 6.75; 95% confidence interval [CI]: 2.71-16.78; P < 0.001) and resting pain scores (AOR: 1.17; 95% CI: 1.04-1.38; P = 0.048). Our findings suggest that pain management patterns adhering to the WHO analgesic ladder can reduce pain severity and pain interference and also control BP in hypertensive patients with chronic musculoskeletal pain.

Association of Social Isolation and Loneliness With Chronic Low Back Pain Among Older Adults: A Cross-sectional Study From Japan Gerontological Evaluation Study (JAGES)

BACKGROUND

Per the biopsychosocial model, pain, especially chronic low back pain, which often presents with nonspecific pain, requires a comprehensive approach involving social factors. However, the association of social factors, including social isolation and loneliness, with this condition remains unclear. This study examined the cross-sectional association of social isolation and loneliness with chronic low back pain among older adults.

METHODS

We recruited functionally independent older adults through a mail survey in 2019 from the Japan Gerontological Evaluation Study (JAGES). Chronic low back pain was defined as low back pain lasting more than 3 months. Social isolation was identified based on face-to-face and non-face-to-face interactions ("not isolated," "isolated tendency," and "isolated"). Loneliness was assessed using the University of California, Los Angeles Loneliness Scale ("not lonely," "lonely tendency," and "lonely").

RESULTS

Consequently, 21,463 participants were analyzed (mean age: 74.4 years; 51.5% females); 12.6% reported chronic low back pain. Multivariable Poisson regression analysis revealed that loneliness was significantly associated with the likelihood of chronic low back pain; compared with "not lonely", the prevalence ratio (PR) was 1.14 (95% confidence interval [CI], 1.05-1.25) for "lonely tendency" and 1.40 (95% CI, 1.27-1.54) for "lonely." Social isolation was not associated; compared with "not isolated," the PR was 0.96 (95% CI, 0.88-1.05) for "isolated tendency" and 0.99 (95% CI, 0.89-1.10) for "isolated." A positive multiplicative interaction between social isolation and loneliness for chronic low back pain was found.

CONCLUSION

Lonelier individuals were more likely to experience chronic low back pain, and those with loneliness and social isolation were synergistically more likely for this condition.

Phenotyping of chronic pain in breast cancer survivors: an original study using the cancer pain phenotyping (CANPPHE) Network multidisciplinary international guidelines

PURPOSE

The primary aim of this cross-sectional study is to examine the prevalence of pain phenotypes in breast cancer survivors (BCS). A secondary aim entails examining whether health related quality of life differs between the main pain phenotypes in BCS.

METHODS

BCS who experienced chronic pain were asked to complete the numeric pain rating scale for pain, Margolis pain diagram, and short form 36 (SF-36). Following administration of questionnaires and quantitative sensory examinations were applied. To determine the prevalence of the predominant type of pain, a recently proposed classification system by the Cancer Pain Phenotyping (CANPPHE) Network was used.

RESULTS

Of the 86 female participants, 19 (22.09%) had dominant neuropathic pain, 18 (20.93%) had dominant nociceptive pain and 14 (16.28%) had dominant nociplastic pain. 35 participants (40.70%) were classified as having mixed pain. One-way ANOVA revealed a significant difference between the four pain groups for the SF-36 general health (F = 3.205, p = 0.027), social functioning (F = 4.093, p = 0.009), and pain (F = 3.603, p = 0.017) subscale scores.

CONCLUSION

This study found that pain in BCS was mostly of mixed phenotype, followed by predominantly neuropathic and nociplastic pain. Furthermore, it was found that, compared to BCS with predominant neuropathic and nociceptive pain, BCS with predominant nociplastic pain have lower health related quality of life in the areas of bodily pain and social functioning.

The Use of Screening Tests in Differential Diagnosis in Nursing Care

Geriatric syndromes involving instability are associated with a higher risk of further complications in patients with trauma requiring subsequent surgery. Acute stroke symptoms require prompt recognition and initiation of reperfusion treatment. This case study describes the patient's stroke symptoms in a timeline and explores the benefit of objective assessment using screening tests and their importance in the differential diagnosis in nursing. Dysphagia is one of the stroke symptoms that can lead to aspiration pneumonia and increase the risk of mortality. This article aims to inform general nurses about the importance of early recognition of dysphagia and other stroke symptoms using adequate screening tests to ensure quality care. Geriatric syndromes encompass instability, resulting in a higher risk of complications, especially in trauma patients. This case study describes a patient with acute ischemic stroke with vague and unrecognized symptoms of dysphagia and explores the rationale for objective screening tests in nursing care.

Development and prospective validation of postoperative pain prediction from preoperative EHR data using attention-based set embeddings

Preoperative knowledge of expected postoperative pain can help guide perioperative pain management and focus interventions on patients with the greatest risk of acute pain. However, current methods for predicting postoperative pain require patient and clinician input or laborious manual chart review and often do not achieve sufficient performance. We use routinely collected electronic health record data from a multicenter dataset of 234,274 adult non-cardiac surgical patients to develop a machine learning method which predicts maximum pain scores on the day of surgery and four subsequent days and validate this method in a prospective cohort. Our method, POPS, is fully automated and relies only on data available prior to surgery, allowing application in all patients scheduled for or considering surgery. Here we report that POPS achieves state-of-the-art performance and outperforms clinician predictions on all postoperative days when predicting maximum pain on the 0-10 NRS in prospective validation, though with degraded calibration. POPS is interpretable, identifying comorbidities that significantly contribute to postoperative pain based on patient-specific context, which can assist clinicians in mitigating cases of acute pain.

Effects of care of multimorbid patients in general practices by advanced practice nurses (FAMOUS): study protocol for a nonrandomized controlled trial

BACKGROUND

Multimorbidity is a common phenomenon among patients treated in general practices. Key challenges within this group include functional difficulties, polypharmacy, treatment burden, fragmentation of care, reduced quality of life and increased health care utilization. These problems cannot be solved in the short consultation time of a general practitioner (GP) since there is an increasing shortage of GPs. In many countries, advanced practice nurses (APNs) are successfully integrated into primary health care for multimorbid patients. The objective of this study is to examine whether the integration of APNs in the primary care of multimorbid patients in Germany leads to optimized care of the target group and to a reduction in the workload of the GPs.

METHODS

The intervention includes the integration of APNs into the care for multimorbid patients in general practice for twelve months. Qualifications for APNs include a master's level academic degree and 500 hours of project-specific training. Their tasks include in-depth assessment, preparation, implementation, monitoring and evaluation of a person-centred and evidence-based care plan. In this nonrandomized controlled trial, a prospective multicentre mixed methods study will be performed. The main inclusion criterion was the cooccurrence of three chronic diseases. For data collection in the intervention group (n = 817), routine data from health insurance companies and association of statutory health insurance physicians (ASHIP) will be used, as well as qualitative interviews. In addition, the intervention will be assessed through documentation of the care process and standardized questionnaires using a longitudinal design. The control group (n = 1634) will receive standard care. For the evaluation, routine data from health insurance companies are matched at a ratio of 1:2. Outcomes will be measured using emergency contacts and GP visits, treatment costs, health status of the patients and the satisfaction of parties involved. The statistical analyses will include Poisson regression to compare outcomes between the intervention and control groups. Descriptive and analytical statistical methods will be used in the longitudinal analysis of the intervention group data. Cost analysis will compare total costs and subgroup costs between the intervention and control groups. Qualitative data will be analysed using content analysis.

DISCUSSION

Challenges to this protocol could include the political and strategic environment as well as the planned number of participants.

Postoperative Pain, Analgesic Choices, and Ileus: A Snapshot from a Teaching Hospital in a Developing Country

Background  Pain relief can be achieved by diversity of methods with analgesics being the basic form of treatment. Analgesic safety and clinical effectiveness are the core factors in determining the analgesic of choice. One adverse effect of concern with opioids is the postoperative ileus (POI).

Objective  In this study, we looked at the severity of postoperative pain, the type of analgesics used to control the pain, and the incidence of POI at Baghdad Teaching Hospital. We hypothesized that we would find an association between the type of analgesia used and POI.

Methods  This observational study was conducted among 100 patients who were residents at the general surgery wards of Baghdad Teaching Hospital. A structured questionnaire was employed focusing on types of analgesics, degree of pain control, and the presence of ileus.

Results  Sixty-nine percent of patients received a combination of opioids and nonopioids. Moderate-to-severe pain was the most commonly reported category on pain scales. More than half of the patients (57%) were found to have POI during their hospital stay and there was a statistically significant association between the type of analgesia and POI development ( p =0.001).

Conclusions  A mix of analgesics (opioids and nonopioids) was the most common regimen at our center. The majority of the surgical inpatients reported having moderate-to-severe pain on both pain scales used in this study. Ileus incidence following abdominal surgeries (61%) was significantly higher than the reported incidence worldwide (10–30%). Postoperative ileus has multifactorial causes, one of which is the use of opioids for pain control. Considering the high incidence of ileus in our center and the association we found between the use of opioids and ileus, further studies should look at the doses of opioids used and whether alternative analgesic methods might result in less ileus.

Effectiveness of High Power Laser Therapy on Pain and Isokinetic Peak Torque in Athletes with Proximal Hamstring Tendinopathy: A Randomized Trial

Athletes such as long-distance runners, sprinters, hockey, and/or football players may have proximal hamstring tendinopathy (PHT). Laser therapy has been shown to be effective in tendinopathies. High power laser therapy (HPLT) is used for the treatment of several musculoskeletal conditions; however, its efficacy on PHT has not been investigated. This study is aimed at examining the effects of HPLT on pain and isokinetic peak torque (IPT) in athletes with PHT. The two-arm comparative pretest-posttest experimental design was used with random allocation of 36 athletes aged 18-35 years into two groups (experimental and conventional group). The experimental group included the application of HPLT for 3 weeks. The conventional group included treatment with a conventional physiotherapy program including ultrasound therapy, moist heat pack, and home exercises for a total of 3 weeks. Pain and IPT of the hamstring muscle were measured before and after the application of the intervention. Pain score decreased, and IPT increased significantly (p < 0.05) after application of HPLT, by 61.26% and 13.18%, respectively. In the conventional group, a significant difference (p < 0.05) was observed in pain scores only, which decreased by 41.14%. No significant difference (p > 0.05) was observed in IPT in the conventional group. When HPLT was compared with conventional physiotherapy, a significant difference was found in pain scores only. HPLT for 3 weeks was found to be effective in improving pain in athletes with PHT. However, no significant difference was found between HPLT and conventional physiotherapy (US, moist heat, and home exercises) in improving the IPT of the hamstring muscle.

Utility of unidimensional and functional pain assessment tools in adult postoperative patients: a systematic review

BACKGROUND

We aimed to appraise the evidence relating to the measurement properties of unidimensional tools to quantify pain after surgery. Furthermore, we wished to identify the tools used to assess interference of pain with functional recovery.

METHODS

Four electronic sources (MEDLINE, Embase, CINAHL, PsycINFO) were searched in August 2020. Two reviewers independently screened articles and assessed risk of bias using the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) checklist.

RESULTS

Thirty-one studies with a total of 12 498 participants were included. Most of the studies failed to meet the methodological quality standards required by COSMIN. Studies of unidimensional assessment tools were underpinned by low-quality evidence for reliability (five studies), and responsiveness (seven studies). Convergent validity was the most studied property (13 studies) with moderate to high correlation ranging from 0.5 to 0.9 between unidimensional tools. Interpretability results were available only for the visual analogue scale (seven studies) and numerical rating scale (four studies). Studies on functional assessment tools were scarce; only one study included an 'Objective Pain Score,' a tool assessing pain interference with respiratory function, and it had low-quality for convergent validity.

CONCLUSIONS

This systematic review challenges the validity and reliability of unidimensional tools in adult patients after surgery. We found no evidence that any one unidimensional tool has superior measurement properties in assessing postoperative pain. In addition, because promoting function is a crucial perioperative goal, psychometric validation studies of functional pain assessment tools are needed to improve pain assessment and management.

Postoperative Pain and Age: A Retrospective Cohort Association Study

BACKGROUND

As the population ages, the number of elderly people undergoing surgery increases. Literature on the incidence and intensity of postoperative pain in the elderly is conflicting. This study examines associations between age and pain-related patient reported outcomes and perioperative pain management in a dataset of surgical patients undergoing four common surgeries: spinal surgery, hip or knee replacement, or laparoscopic cholecystectomy. Based on the authors' clinical experience, they hypothesize that pain scores are lower in older patients.

METHODS

In this retrospective cohort, study data were collected between 2010 and 2018 as part of the international PAIN OUT program. Patients filled out the International Pain Outcomes Questionnaire on postoperative day 1.

RESULTS

A total of 11,510 patients from 26 countries, 59% female, with a mean age of 62 yr, underwent one of the aforementioned types of surgery. Large variation was detected within each age group for worst pain, yet for each surgical procedure, mean scores decreased significantly with age (mean Numeric Rating Scale range, 6.3 to 7.3; β = -0.2 per decade; P ≤ 0.001), representing a decrease of 1.3 Numeric Rating Scale points across a lifespan. The interference of pain with activities in bed, sleep, breathing deeply or coughing, nausea, drowsiness, anxiety, helplessness, opioid administration on the ward, and wish for more pain treatment also decreases with age for two or more of the procedures. Across the procedures, patients reported being in severe pain on postoperative day one 26 to 38% of the time, and pain interfered moderately to severely with movement.

CONCLUSIONS

The authors' findings indicate that postoperative pain decreases with increasing age. The change is, however, small and of questionable clinical significance. Additionally, there are still too many patients, at any age, undergoing common surgeries who suffer from moderate to severe pain, which interferes with function, supporting the need for tailoring care to the individual patient.

EDITOR’S PERSPECTIVE

Influence of interpretation of pain scores on patients' perception of pain: A prospective study

Background and Aims:

Assessment of pain using pain scales is essential. In the Numeric Rating Scale (NRS), patients are asked to score their pain intensity on a scale from 0 to 10 (10- worst pain). This requires some abstract thinking by the patient, also the pain scores (PS) may not essentially communicate the patients’ need for more analgesia. We planned a study to evaluate the change in patients’ self-assessed PS after understanding clinical interpretation of the NRS.

Methods:

This prospective study was registered after approval from our hospital ethics board. Sample size estimated for the trial was 360 patients. All postoperative patients were recruited after informed consent. Patients having prolonged stay in Intensive Care Unit (more than 48 h), or those who underwent emergency surgeries were excluded. During Acute Pain Service (APS) rounds, patients were asked to rate their PS on the NRS. This was followed by a briefing about the clinical interpretation of the scale, and the patients were asked to re score their pain using the same scale. The change in pain severity was compared using Chi-square test.

Results:

Following explanation, a change in severity was seen for PS at rest [X² (9, N- 360) = 441, P < 0.001] and at movement [X² (9, N- 360) = 508, P < 0.001]. Overall, a change in PS severity was seen in 162 patients (45%). A decrease and an increase in the severity of pain was seen in 119 and 41 patients respectively.

Conclusion:

Explaining the clinical interpretation of PS on a NRS does lead to a change in patients’ self-assessed PS.

Increase in early wound leakage in total knee arthroplasty with local infiltrative analgesia (LIA) that includes epinephrine: a retrospective cohort study

Background and purpose - After introducing a new local infiltration anesthesia (LIA) protocol with addition of 30 mL ropivacaine 2% and 1 mg epinephrine, we noted an increase in early wound leakage. As wound leakage is associated with prosthetic joint infection, our department aims to minimize postoperative wound leakage. This study evaluates the incidence of early wound leakage and postoperative pain after knee arthroplasty (KA) following adjustment of the LIA protocol with addition of 30 cc ropivacaine 2% and 1 mg epinephrine. Patients and methods - In this retrospective medical dossier study all patients (n = 502) undergoing a primary total or unicondylar knee arthroplasty between January 1, 2018 and July 1, 2019 were included. Patients received an LIA protocol containing 120 mL 2 mg/mL ropivacaine (ROPI- group; n = 256). After October 30, patients received an LIA protocol containing 150 mL 2 mg/mL ropivacaine with 1 mg epinephrine in the first 100 mL (ROPI + group; n = 246). The primary outcome measure was early wound leakage (< 72 hours postoperatively), defined as wound fluid leaking past the barrier of the wound dressing. Secondary outcome measure, 10-point numeric rating scale (NRS) pain (< 72 hours postoperatively) was also assessed. Data was evaluated using logistic regression. Results - The incidence of wound leakage was higher in the ROPI + group: 24% versus 17% in the ROPI- group (p = 0.06). After adjusting for the differences between surgeons the relative risk of this increase was 1.4 (1.0-2.0). The ROPI + and ROPI- group were similar regarding postoperative pain assessment. Interpretation - Adjustment of the LIA protocol with 30 mL 2% ropivacaine and 1 mg epinephrine led to an increase in early wound leakage in knee arthroplasty but no difference in pain scores.

Six-year trends in postoperative prescribing and use of multimodal analgesics following total hip and knee arthroplasty: A single-site observational study of pain management

BACKGROUND

Guidelines for acute postoperative pain management recommend administering analgesics in multimodal combination to facilitate synergistic benefit, reduce opioid requirements and decrease side-effects. However, limited observational research has examined the extent to which multimodal analgesics are prescribed and administered postoperatively following joint replacement.

METHODS

In this longitudinal study, we used three-point prevalence surveys to observe the 6-year trends in prescribing and use of multimodal analgesics on the orthopaedic wards of a single Australian private hospital. We collected baseline postoperative data from total hip and knee arthroplasty patients in May/June 2010 (Time 1, n = 86), and follow-up data at 1 year (Time 2, n = 199) and 5 years (Time 3, n = 188). During the follow-up, data on prescribing practices were presented to anaesthetists.

RESULTS

We found a statistically significant increase in the prescribing (p < 0.001) and use (p < 0.001) of multimodal analgesics over time. The use of multimodal analgesics was associated with lower rest pain (p = 0.027) and clinically significant reduction in interference with activities (p < 0.001) and sleep (p < 0.001). However, dynamic pain was high and rescue opioids were likely under-administered at all time points. Furthermore, while patients reported high levels of side-effects, use of adjuvant medications was low.

CONCLUSIONS

We observed significant practice change in inpatient analgesic prescribing in favour of multimodal analgesia, in keeping with contemporary recommendations. Surveys, however, appeared to identify a clinical gap in the bedside assessment and management of breakthrough pain and medication side-effects, requiring additional targeted interventions.

SIGNIFICANCE

Evaluation of 6-year trends in a large Australian metropolitan private hospital indicated substantial growth in postoperative multimodal analgesic prescribing. In the context of growing global awareness concerning multimodal analgesia, findings suggested diffusion of best-evidence prescribing into clinical practice. Findings indicated the effects of postoperative multimodal analgesia in real-world conditions outside of experimental trials. Postoperative multimodal analgesia in the clinical setting was only associated with a modest reduction in rest pain, but substantially reduced interference from pain on activities and sleep.

The association of patients' daily summarized self-rated "real-time" pain scores with physical recovery after major surgery - A repeated measurement design

Aim

To determine the associations of patients' documented self-rated pain with self-rated early postoperative physical recovery.

Design

Observational with repeated measures.

Methods

General and orthopaedic inpatients (N = 479) were during the period 2012-2015 screened for pain. Individual daily median pain scores at rest and during activity were based on 4-9 self-ratings on postoperative days 1 and 2, using the Numeric Rating Scale. Nine items reflecting physical recovery from the "Postoperative Recovery Profile" were used in a questionnaire.

Results

Associations between median pain scores on postoperative day 1 and physical recovery (fatigue, sleeping difficulties, bladder function, mobilization, muscle weakness and personal hygiene) the same day were found. Additionally, associations were found between median pain scores on day 1 and physical recovery (fatigue, sleeping difficulties, mobilization and muscle weakness) on day 2.

The relationship between physical activity and appetite in patients with heart failure: A prospective observational study

INTRODUCTION

Physical activity and appetite are important components for maintaining health. Yet, the association between physical activity and appetite in heart failure (HF) populations is not completely understood. The aim of the present study was to investigate the relationship between physical activity, functional capacity, and appetite in patients with HF.

METHODS

This was a prospective observational study. In total, 186 patients diagnosed with HF, New York Heart Association (NYHA) class II-IV (mean age 70.7, 30% female), were included. Physical activity was measured using a multi-sensor actigraph for seven days and with a self-reported numeric rating scale. Physical capacity was measured by the six-minute walk test. Appetite was measured using the Council on Nutrition Appetite Questionnaire. Data were collected at inclusion and after 18 months. A series of linear regression analyses, adjusted for age, NYHA class, and B-type natriuretic peptide were conducted.

RESULTS

At baseline, higher levels of physical activity and functional capacity were significantly associated with a higher level of appetite in the unadjusted models. In the adjusted models, number of steps ( p = 0.019) and the six-minute walk test ( p = 0.007) remained significant. At the 18-month follow-up, all physical activity variables and functional capacity were significantly associated with appetite in the unadjusted regression models. In the adjusted models, number of steps ( p = 0.001) and metabolic equivalent daily averages ( p = 0.040) remained significant.

CONCLUSION

A higher level of physical activity measured by number of steps/day was associated with better self-reported appetite, both at baseline and the 18-month follow-up. Further research is needed to establish causality and explore the intertwined relationship between activity and appetite in patients with HF.

Falls After Total Knee Arthroplasty: Frequency, Circumstances, and Associated Factors-A Prospective Cohort Study

BACKGROUND

Individuals with total knee arthroplasty (TKA) often experience pain and reduced balance control, which may predispose them to greater fall risk.

OBJECTIVE

The objective of this study was to determine the frequency and circumstance of falls and fall-related risk factors within a 6-month follow-up period in individuals after TKA.

DESIGN

This study was a prospective cohort study.

METHODS

Knee proprioception, the Balance Systems Evaluation Test, knee pain, knee extension and flexion muscle strength, knee range of motion, and balance confidence were evaluated in 134 individuals (39 men, 95 women; mean age = 66.3 years [SD = 6.6 years]) 4 weeks after TKA. Monthly follow-up sessions, via face-to-face or telephone interviews, were implemented to obtain data on fall incidence over 6 months.

RESULTS

Twenty-three individuals after TKA (17.2%) sustained at least 1 fall during the 6-month follow-up period. The median time of the first fall episode was 15 weeks after TKA. Of the 31 fall episodes, most occurred during walking (67.7%). Slipping (35.5%) and tripping (35.5%) were identified as the most frequent causes of falling. Most falls occurred at home (45.2%) or another indoor environment (29.0%). Multivariate binary logistic regression revealed that younger age (odds ratio: 0.91), reduced proprioception of the knee that had undergone surgery ("operated knee") (odds ratio: 1.62), reduced sensory orientation (odds ratio: 0.92), and greater operated knee pain (odds ratio: 1.68) were significantly associated with more falls during the follow-up period.

LIMITATIONS

The results of this study may be generalizable up to 6 months after TKA.

CONCLUSIONS

Intervention efforts should target deficits in knee proprioception and sensory orientation and operated knee pain to prevent future falls in individuals with TKA.

The effectiveness of lying surfaces in nursing care beds, a comparison of spring element systems versus conventional systems: A post marketing clinical follow-up pilot study

BACKGROUND

Reduced mobility is a strong risk factor for pressure ulcer development in a nursing home setting. Despite this, there is a surprising lack of data regarding suitable nursing care beds in general and the prevention of pressure ulcers provided by lying surface systems in particular. In this context we aimed to assess the mobility of patients using lying surface systems either with spring elements (SES) and to compare these to conventional systems (CS; wooden slats or steel bars).

METHODS

This was a prospective, randomized, controlled study in 29 patients with an age range of 54-95 years. Patients were randomly assigned to SES (n = 15) or CS (n = 14). The primary objective was to show a statistically significant difference in the proportion of patients with normal (up to 4 movements per hour) movements as evaluated by the Mobility Monitor^®. Pressure distribution of the lying body weight was measured by a full body pressure mapping system XSensor^®. Comfort, possibility of movement and recovery of sleep as well as pain at rest were self-rated.

RESULTS

We screened a total of 39 patients of which 29 were eligible to be randomized into the two groups and 27 were finally analysed (SES = 14; CS = 13). The mean age was 81.7 ± 9.5 years, 81.5% were female and the mean Braden Scale Score 22.4 ± 1.3. We observed no statistically significant difference in the primary evaluation criterion (proportion of patients with a normal number of movements across 14 nights) between the SES group (81.4 ± 10.8%) and the CS group (72.9 ± 16.3%; p = 0.0757). There was a consistent trend for more movements in the normal range in the SES group however, which was observed when the number of hours with normal movement was plotted per night (p = 0.0004). Measured pressure values showed overall higher values for the lateral compared to the dorsal position with the SES but not the CS forming a "shoulder" between 35-55 mmHg in the dorsal position and between 35-45 mmHg in the lateral position. Self-rated comfort was significantly higher with the SES after night 14 (p = 0.0192) than with CS.

CONCLUSIONS

The study is not aimed at the hard endpoint pressure ulcer, but at the physiological movement profile of patients in bed, which justifies a much smaller number of cases. For elderly nursing home patients it appears that beds with spring elements may be associated with higher normality of body movements and higher self-rated comfort. The presented study could be a contribution to reduce the care dependency of patients regarding mobility.

The Rotterdam Elderly Pain Observation Scale (REPOS) is reliable and valid for non-communicative end-of-life patients

BACKGROUND

In palliative care, administration of opioids is often indispensable for pain treatment. Pain assessment may help recognize pain and guide treatment in non-communicative patients. In the Netherlands the Rotterdam Elderly Pain Observation Scale (REPOS) is recommended to this aim, but not yet validated. Therefore the objective of this study was to validate the REPOS in non-communicative or unconscious end-of-life patients.

METHODS

In this observational study, the primary researcher applied the REPOS, while both the researcher and a nurse applied the Numeric Rating Scale (NRS). If possible, the patient in question applied the NRS as well. The NRS scores were compared with the REPOS scores to determine concurrent validity. REPOS scores obtained before and after a pain-reducing intervention were analysed to establish the scale's sensitivity to change.

RESULTS

A total of 183 REPOS observations in 100 patients were analysed. Almost 90% of patients had an advanced malignancy; observations were done a median of 3 days (IQR 1 to 13) before death. Internal consistency of the REPOS was 0.73. The Pearson product moment correlation coefficient ranged from 0.64 to 0.80 between REPOS and NRS scores. REPOS scores declined with median 2 points (IQR 1 to 4) after a pain-reducing intervention (p < 0.001). Optimal sensitivity (0.81) and specificity (0.62) were found at cut-off score 3.

CONCLUSIONS

This study demonstrates that the REPOS has promising psychometric properties for pain assessment in non-communicative end-of-life patients. Its application may be of additional value to relieve suffering, including pain, in palliative care.

Self-report pain assessment tools for cognitively intact older adults: Integrative review

BACKGROUND

Pain is common in older adults, but it is often underreported or undertreated partly because many consider pain to be a normal consequence of ageing. Among the plethora of available self-report pain assessment tools, there is no synthetised evidence which tools are indicated for use among cognitively intact older adults.

PURPOSE OF THE STUDY

To understand documented self-report pain assessment tools that have been used among cognitively intact older adults, and to describe their characteristics including overall performance as well as studies demonstrating their use.

METHODS

A systematic search of the indexed databases PubMed, PsycINFO and Cumulative Index to Nursing and Allied Health Literature (CINAHL Plus) was conducted to identify documented self-report pain assessment tools through peer-reviewed papers, including citations from January 1990 to December 2015. Thirty-five percentage of abstracts were independently evaluated by two raters according to specific criteria.

RESULTS

Among identified tools, the Iowa Pain Thermometer, the 6-point Verbal Descriptor Scale, the Numeric Rating Scale, the short form Brief Pain Inventory (BPI) and the Geriatric Pain Measure (GPM) may be suitable tools for self-reported pain by cognitively intact older adults based on the statement of the literature. Only two self-report tools (the GPM and the Geriatric Painful Events Inventory) were designed specifically for older adults.

CONCLUSIONS

More studies are needed to evaluate pain measures' psychometric performance across different settings, racial/ethnic groups and disease categories. Since 80% of older adults have at least one chronic disease, multidimensional tools such as the GPM may need to be used more often for accurate self-report of pain.

IMPLICATIONS FOR PRACTICE

Examining the psychometric properties of comprehensive self-report pain assessment tools informs recommendations for the selection of tools to be used in clinical practice.

Low back pain in older adults: risk factors, management options and future directions

Low back pain (LBP) is one of the major disabling health conditions among older adults aged 60 years or older. While most causes of LBP among older adults are non-specific and self-limiting, seniors are prone to develop certain LBP pathologies and/or chronic LBP given their age-related physical and psychosocial changes. Unfortunately, no review has previously summarized/discussed various factors that may affect the effective LBP management among older adults. Accordingly, the objectives of the current narrative review were to comprehensively summarize common causes and risk factors (modifiable and non-modifiable) of developing severe/chronic LBP in older adults, to highlight specific issues in assessing and treating seniors with LBP, and to discuss future research directions. Existing evidence suggests that prevalence rates of severe and chronic LBP increase with older age. As compared to working-age adults, older adults are more likely to develop certain LBP pathologies (e.g., osteoporotic vertebral fractures, tumors, spinal infection, and lumbar spinal stenosis). Importantly, various age-related physical, psychological, and mental changes (e.g., spinal degeneration, comorbidities, physical inactivity, age-related changes in central pain processing, and dementia), as well as multiple risk factors (e.g., genetic, gender, and ethnicity), may affect the prognosis and management of LBP in older adults. Collectively, by understanding the impacts of various factors on the assessment and treatment of older adults with LBP, both clinicians and researchers can work toward the direction of more cost-effective and personalized LBP management for older people.

Culturally Conscientious Pain Measurement in Older African Americans

Despite considerable pain disparities across the care continuum, pain is an understudied health problem in older ethnic minority groups, such as African Americans. Quality pain measurement is a core task in pain management and a mechanism by which pain disparities may be reduced. Pain measurement includes the methods (e.g., assessment approaches, tools) and metrics that researchers and clinicians use to understand the characteristics of pain. However, there are significant issues and gaps that negatively affect pain measurement in older African Americans. Of concern is insufficient representation in pain research, which impedes the testing and refinement of many standardized self-report, behavioral and surrogate report, physiological, and composite measures of pain. The purposes for this article are to discuss the status of pain measurement and factors that affect our knowledge on pain measurement in older African Americans, and to provide guidance for culturally conscientious pain measurement using the available literature.

Pain among hospitalized older people with heart failure and their preparation to manage this symptom on discharge: a descriptive-observational study

Globally, heart failure (HF) is one of the major health issues faced by many older people. It causes significant symptom burden that requires ongoing management. This paper reports on a descriptive-observational study undertaken to: (1) describe the prevalence of pain and analgesic prescription usage in hospitalized older HF patients; (2) determine the degree to which these patients are provided with a pain self-management strategy prior to discharge; and (3) determine if the patients' pain self-management strategy has been detailed in the discharge summary. A total of 122 older HF patients were included in this study. Results indicated that moderate to severe pain (Numeric Rating Scale score ≥4) is experienced by a substantial number of older people hospitalized with HF. There is little documented evidence that older people are provided with adequate analgesic prescriptions and the instructions required to effectively manage their pain on discharge to the community.

The relative meaning of absolute numbers: the case of pain intensity scores as decision support systems for pain management of patients with dementia

Background

Assessment and management of pain in patients with dementia is known to be challenging, due to patients’ cognitive and/or communication difficulties. In the UK, pain in hospital is managed through regular assessments, with the use of pain intensity scores as triggers for action. The aim of this study was to understand current pain assessment practices, in order to later inform the development of a decision support tool designed to improve the management of pain for people with dementia in hospital.

Methods

An exploratory study was conducted in four hospitals in the UK (11 wards), with observations of patients with dementia (n = 31), interviews of staff (n = 52) and patients’ family members (n = 4) and documentary analysis. A thematic analysis was carried out, structured along dimensions of decision making. This paper focuses on the emergent themes related to the use of assessment tools and pain intensity scores.

Results

A variety of tools were used to record pain intensity, usually with numerical scales. None of the tools in actual use had been specifically designed for patients with cognitive impairment. With patients with more severe dementia, the patient’s body language and other cues were studied to infer pain intensity and then a score entered on behalf of the patient. Information regarding the temporality of pain and changes in pain experience (rather than a score at a single point in time) seemed to be most useful to the assessment of pain.

Conclusions

Given the inherent uncertainty of the meaning of pain scores for patients with dementia, numerical scales were used with caution. Numerical scores triggered action but their meaning was relative - to the patient, to the clinician, to the time of recording and to the purpose of documenting. There are implications for use of data and computerized decision support systems design. Decision support interventions should include personalized alerting cut-off scores for individual patients, display pain scores over time and integrate professional narratives, mitigating uncertainties around single pain scores for patients with dementia.

[Pain management nursing in hospitalized patients with non-oncological diseases]

AIM

To assess pain management in patients hospitalized with a non-oncological disease and evaluate factors involved in pain assessment.

METHODS

A descriptive, cross-sectional study. We reviewed pain episodes documented in the medical records of 105 patients aged>18 years admitted to the medical units of a regional hospital between September and December 2014. Reports of pain episodes were evaluated by assessing 22 variables related to pain management quality criteria.

RESULTS

A total of 184 reports were reviewed. Pain was measured using the visual analogue scale (VAS) in 70.1% of patients (n=129); pain was reassessed in 44.3% (n=54) of patients. Pain reassessment was significantly more frequent in patients aged<70 years, as compared to older patients (53.1 vs. 26.8%, respectively; p=0.01). Pain was more frequently considered to be unrelated to the cause of admission in women as compared to men (50 vs. 25.7% p=0.027). Pain was identified in the patient care plan as a collaborative problem by the nurse for 21.1% of the patients.

CONCLUSIONS

Some aspects of pain management should be improved, especially those regarding pain description and reassessment. The age and sex of patients significantly influence the approach of pain.

Clinical utility of an undersized nurse-operated recovery room in the postoperative course: results from an Italian community setting

PURPOSE

In Europe, standardized criteria for recovery room (RR) requirements have not been established. The purpose of this study was to examine the clinical utility of an undersized nurse-operated RR in an Italian community hospital.

DESIGN

Single-center observational study.

METHODS

A total of 1,945 consecutive surgical patients admitted to the RR at the study institution between September 31, 2009, and August 31, 2011, were included in the study. A control group of surgical patients not admitted to the RR, matched for age, gender, American Society of Anesthesiologists score, and type of surgery were also considered. The prevalence of early adverse events occurring within 3 hours of the end of surgery was compared between the two groups.

FINDINGS

Patients admitted to the RR (mean age, 73.6 ± 14.2 years; 42.2% male; and 76.3% having major surgery) showed lower prevalences of hypotension (P < .0001), hypertensive response (P < .0001), new arrhythmias requiring intervention (P = .0036), and oxygen desaturation (P < .0001) in comparison with the control group. No differences in the proportions of patients experiencing postoperative nausea and vomiting, shivering, bleeding, and respiratory events were found. The Numeric Rating Scale for pain was also significantly lower at 2 hours in the study group as compared to the control group (1 [0 to 5] vs 3 [1 to 7]; P < .0001).

CONCLUSION

In this Italian community setting, an undersized nurse-operated RR contributed to a reduced prevalence of adverse postoperative events.

Public health imperative of the 21st century: innovations in palliative care systems, services, and supports to improve health and well-being of older americans

A primary aim of federal aging and health policy must be promoting innovations in palliative care systems, services, and supports that improve the experience of growing old in America. Older adults must contend today with increasing burden over the life course often as the result of life-limiting chronic pain and chronic illnesses as well as social and economic factors beyond their control. These burdens are frequently shared with unpaid family caregivers who provide significant uncompensated medical care and social support to their loved ones. Enjoyment of the highest attainable standard of physical and mental health, recognized as a fundamental human right under international law, remains a goal for all older adults and encompasses the right to palliative care. For many older Americans, especially vulnerable subgroups who face health and pain disparities, however, this goal remains elusive. A public health strategy for implementing palliative care policy interventions will help to build age-friendly environments, assure the availability and accessibility of palliative systems of care, essential medicines, and an adequate generalist-level workforce, and sustain diffusion of innovation across all levels of health and social provision. The 2015 White House Conference on Aging must make these realignments a policy priority in order to foster social and economic development for all older Americans.

The effect of patient sex on the incidence of early adverse effects in a population of elderly patients

Patient sex is known to influence the response to general and regional anaesthesia and recovery after surgery. However, most studies come from analyses carried out on middle-aged patients. As most of the patients admitted to the post-anaesthesia recovery room in our institution are elderly, we took the opportunity to investigate the association between sex and incidence of early adverse events in this older population of patients after major surgery. Consecutive patients undergoing general, orthopaedic, urological and gynaecological surgery, admitted to the recovery room of our institution over a 15-month period, were retrospectively studied. The following adverse events were considered in the analysis: shivering, postoperative nausea and vomiting, hypotension and hypertensive responses, new arrhythmias requiring treatment, acute respiratory failure and desaturation. A total of 1347 patients (mean age 73.3±15.1 years, 61.4% women) were included. Women showed a higher incidence of shivering (relative difference +48%, P=0.0003), postoperative nausea and vomiting (+91%, P<0.0001), hypotension (+32%, P=0.044) and desaturation (+60%, P=0.0030) than men. The incidence of hypertensive response, arrhythmias and acute respiratory failure were not statistically significantly different. The findings of this exploratory study suggest that women have a higher risk of early postoperative adverse events even in a more elderly population.

New health care measures: emphasis on better management of postsurgical pain and postoperative nausea and vomiting

Value-based purchasing and the Hospital Consumer Assessment of Healthcare Providers and Systems are tying patient-centric measures to reimbursements. Hospitals should be particularly concerned about management of postoperative pain and control of postoperative nausea and vomiting (PONV), known to adversely impact overall patient satisfaction. Anesthesiologists are likely to be on the frontlines of these transitions. Although postoperative pain is not always effectively managed, clinicians have the pharmacological tools and guidelines for better pain control. Considerable work has been done in PONV to better identify high-risk patients and effective prophylactic agents. Postoperative pain control and preventing PONV are two relatively straightforward ways to respond to new quality metrics. The aim of this review is to raise practitioner awareness of these new quality metrics and provide an overview of the current tools and methods used to improve postoperative pain control and PONV.

Effectiveness of multidisciplinary rehabilitation treatment for patients with chronic pain in a primary health care unit

Background In recent years, multidisciplinary rehabilitation (MDR) became an alternative treatment option for chronic non-cancer pain. MDR is mostly available in specialized pain units, usually at rehabilitation centers where the level of knowledge and therapeutically options to treat pain conditions are considered to be high. There is strong evidence that MDR in specialized pain units is affecting pain and improves the quality of life in a sustainable manner. There are few studies about MDR outcome in primary health care, especially in those units situated in rural areas and with a different population than that encountered in specialized hospitals. That, in spite of the fact that the prevalence of pain in the patients treated in primary care practice is about 30%. The aim of this study is to analyze the effectiveness of MDR for chronic non-cancer patients in a primary health care unit. Methods This study included a total of 51 patients with chronic pain conditions who were admitted and completed the local MDR-program at the primary health care unit in Arvika, Sweden. The major complaint categories were fibromyalgia (53%), pain from neck and shoulder (28%) or low back pain (12%). The inclusion criteria were age between 16 and 67 years and chronic non-cancer pain with at least 3 months duration. The multidisciplinary team consisted of a general practitioner, two physiotherapists, two psychologists and one occupational therapist. The 6-week treatment took place in group sessions with 6-8 members each and included cognitive-behavioral treatment, education on pain physiology, ergonomics, physical exercises and relaxation techniques. Primary outcomes included pain intensity, pain severity, anxiety and depression scores, social and physical activity, and secondary outcomes were sick leave, opioid consumption and health care utilization assessed in the beginning of the treatment and at one year follow-up. Data was taken from the Swedish Quality Register for Pain Rehabilitation (SQRP) and the patients' medical journal. Results One year after MDR treatment, sick leave decreased from 75.6% to 61.5% (p <0.05). Utilization of health-care during one year decreased significantly from 27.4 to 20.1 contacts (p = 0.02). There were significant improvements concerning social activity (p = 0.03) and depression (p <0.05), but not in anxiety (p = 0.1) and physical activity (p = 0.08). Although not statistically significant, some numerical decrease in the mean levels of pain intensity, pain severity and opioid consumption were reported one year after MDR (p > 0.05). Conclusions The results obtained one year after rehabilitation indicated that patients with chronic noncancer pain might benefit from MDR in primary health care settings. Implications This study suggests that MDR in primary care settings as well as MDR at specialized pain units may lead to better coping in chronic non-cancer pain conditions with lower depression scores and higher social activity, leading to lower sick leave. This study demonstrated that there is a place for MDR in primary health care units with the given advantage of local intervention in rural areas allowing the patients to achieve rehabilitation in their home environment.
