Measuring pain as the 5th vital sign does not improve quality of pain management

Evidence-based pain medicine for primary care physicians

The last several decades have seen a marked increase in both the recognition and treatment of chronic pain. Unfortunately, patients frequently misunderstand both the nature of pain and the best practices for its treatment. Because primary care physicians treat the majority of chronic pain, they are ideally situated to provide evidence-based pain care. The majority of the medical evidence supports a biopsychosocial model of pain that integrates physical, emotional, social, and cultural variables. The goal of this primer is to assist primary care physicians in their understanding of pain, evaluation of the chronic pain patient, and ability to direct evidence-based care. This article will discuss the role of physical rehabilitation, pain psychology, pharmacotherapy, and procedural interventions in the treatment of chronic pain. Given the current epidemic of drug-related deaths, particular emphasis is placed on the alternatives to opioid therapy. Unfortunately, death is not the only significant complication from opioid therapy, and this article discusses many of the most common side effects. This article provides general guidelines on the most appropriate utilization of opioids with emphasis on the recent Centers for Disease Control and Prevention guidelines, risk stratification, and patient monitoring. Finally, the article concludes with the critical role that a pain medicine specialist can play in the management of patients with chronic pain.

The Fifth Vital Sign: Postoperative Pain Predicts 30-day Readmissions and Subsequent Emergency Department Visits

OBJECTIVE

We hypothesized that inpatient postoperative pain trajectories are associated with 30-day inpatient readmission and emergency department (ED) visits.

BACKGROUND

Surgical readmissions have few known modifiable predictors. Pain experienced by patients may reflect surgical complications and/or inadequate or difficult symptom management.

METHODS

National Veterans Affairs Surgical Quality Improvement data on inpatient general, vascular, and orthopedic surgery from 2008 to 2014 were merged with laboratory, vital sign, health care utilization, and postoperative complications data. Six distinct postoperative inpatient patient-reported pain trajectories were identified: (1) persistently low, (2) mild, (3) moderate or (4) high trajectories, and (5) mild-to-low or (6) moderate-to-low trajectories based on postoperative pain scores. Regression models estimated the association between pain trajectories and postdischarge utilization while controlling for important patient and clinical variables.

RESULTS

Our sample included 211,231 surgeries-45.4% orthopedics, 37.0% general, and 17.6% vascular. Overall, the 30-day unplanned readmission rate was 10.8%, and 30-day ED utilization rate was 14.2%. Patients in the high pain trajectories had the highest rates of postdischarge readmissions and ED visits (14.4% and 16.3%, respectively, P < 0.001). In multivariable models, compared with the persistently low pain trajectory, there was a dose-dependent increase in postdischarge ED visits and readmission for pain-related diagnoses, but not postdischarge complications (χ trend P < 0.001).

CONCLUSIONS

Postoperative pain trajectories identify populations at risk for 30-day readmissions and ED visits, and do not seem to be mediated by postdischarge complications. Addressing pain control expectations before discharge may help reduce surgical readmissions in high pain categories.

Psychometric evaluation of the Chinese version of the revised American Pain Society Patient Outcome Questionnaire concerning pain management in Chinese orthopedic patients

The present study tested the clinical efficiency (item grouping, internal consistency of the subscales, construct validity, and clinical feasibility) of a widely used pain assessment system, the Mandarin version of the American Pain Society Patient Outcome Questionnaire (APS-POQ-R-C), in Chinese patients. We also attempted to investigate the current quality of pain management provided in orthopedic inpatient units in China and provide baseline data. First, we investigated the test–retest reliability of APS-POQ-R-C. In total, 236 orthopedic patients were evaluated. Our results showed that APS-POQ-R-C has satisfactory internal consistency and construct validity, although some items are not appropriate for orthopedic patients. Test–retest reliability outcomes indicated that APS-POQ-R-C is a satisfactory battery with acceptable validity and reliability, and is therefore recommended for pain management in future studies.

An Osteopathic Approach to Chronic Pain Management

Chronic pain reduces quality of life and productivity, costing billions in health care dollars and lost revenue. Physicians routinely prescribe opioids, which has led to opioid addiction and overdose. The US surgeon general recommends nonpharmacologic treatment for patients with chronic pain. A paradigm shift is necessary for patients to partner with physicians to take control of their own health. This article outlines the cognitive behavioral approaches, nonopioid therapies, and nonpharmacologic therapies that osteopathic physicians can integrate in their treatment of patients with chronic pain.

Screening using the fifth vital sign in the electronic medical recording system

Purpose

To investigate the usefulness of screening for patient symptoms as the fifth vital sign using an electronic medical recording system.

Patients and methods

In the electronic medical recording system, all admitted patients received routine nurse-based assessment of discomfort (defined as any physical symptom) at every vital sign check regarding item 2 of the Support Team Assessment Schedule Japanese version (STAS-J). All cancer patients admitted to oncology units were screened at 1-week intervals. Screening-positive was defined when patients had a STAS-J score of 2 or more at least two times in a week. For all screening-positive patients, the palliative care team reviewed each patient's medical records, and provided written recommendations as needed. The primary outcomes were the proportion of screening-positive patient, and the proportion of patients deemed to need additional palliative treatment in the screening-positive patients.

Results

Of 2427 patients screened, 223 (9.1%; 95% confidence interval, 8-10%) met the screening-positive criterion. A total of 12 (5.4%; 95% confidence interval, 3-9%) of them were deemed to need additional palliative care, including six patients referred to the PCT within 1 week. In the remaining 211 screening-positive patients, 100 had received adequate palliative care, 68 had already been referred to the palliative care team and 43 had self-limiting transient discomfort.

Conclusion

This screening system was feasible but the majority of screening-positive patients did not require additional palliative care interventions.

[Optimizing post-operative pain management in Latin America]

Post-operative pain management is a significant problem in clinical practice in Latin America. Insufficient or inappropriate pain management is in large part due to insufficient knowledge, attitudes and education, and poor communications at various levels. In addition, the lack of awareness of the availability and importance of clear policies and guidelines for recording pain intensity, the use of specific analgesics and the proper approach to patient education have led to the consistent under-treatment of pain management in the region. However, these problems are not insurmountable and can be addressed at both the provider and patient level. Robust policies and guidelines can help insure continuity of care and reduce unnecessary variations in practice. The objective of this paper is to call attention to the problems associated with Acute Post-Operative Pain (APOP) and to suggest recommendations for their solutions in Latin America. A group of experts on anesthesiology, surgery and pain developed recommendations that will lead to more efficient and effective pain management. It will be necessary to change the knowledge and behavior of health professionals and patients, and to obtain a commitment of policy makers. Success will depend on a positive attitude and the commitment of each party through the development of policies, programs and the promotion of a more efficient and effective system for the delivery of APOP services as recommended by the authors of this paper. The writing group believes that implementation of these recommendations should significantly enhance efficient and effective post-operative pain management in Latin America.

Providing chronic pain management in the "Fifth Vital Sign" Era: Historical and treatment perspectives on a modern-day medical dilemma

BACKGROUND

Over 100 million Americans are living with chronic pain, and pain is the most common reason that patients seek medical attention. Despite the prevalence of pain, the practice of pain management and the scientific discipline of pain research are relatively new fields compared to the rest of medicine - contributing to a twenty-first century dilemma for health care providers asked to relieve suffering in the "Fifth Vital Sign" era.

METHODS

This manuscript provides a narrative review of the basic mechanisms of chronic pain and history of chronic pain management in the United States - including the various regulatory, health system and provider factors that contributed to the decline of multidisciplinary pain treatment in favor of the predominant opioid treatment strategy seen today. Multiple non-opioid pain treatment strategies are then outlined. The manuscript concludes with three key questions to help guide future research at the intersection of pain and addiction.

CONCLUSIONS

The assessment and treatment of chronic pain will continue to be one of the most common functions of a health care provider. To move beyond an over reliance on opioid medications, the addiction and pain research communities must unite with chronic pain patients to increase the evidence base supporting non-opioid analgesic strategies.

National Trends in Antidepressant, Benzodiazepine, and Other Sedative-Hypnotic Treatment of Older Adults in Psychiatric and Primary Care

OBJECTIVE

To describe how use of antidepressants, benzodiazepines, and other anxiolytic/sedative-hypnotics among older adults (age ≥ 65 years) has changed over time among visits to primary care providers and psychiatrists.

METHODS

Data were from the National Ambulatory Medical Care Survey (years 2003-2005 and 2010-2012), a nationally representative cross-section of outpatient physician visits. Analysis focused on visits to primary care providers (n = 14,282) and psychiatrists (n = 1,095) at which an antidepressant, benzodiazepine, or other anxiolytic/sedative-hypnotic was prescribed, which were stratified by demographic and clinical characteristic (including ICD-9-CM diagnosis) and compared across study intervals. Odds of medication use were calculated for each stratum, adjusting for demographic and clinical characteristics.

RESULTS

The visit rate by older adults to primary care providers where any of the medications were prescribed rose from 16.4% to 21.8% (adjusted odds ratio [AOR] = 1.43, P < .001) while remaining steady among psychiatrists (75.4% vs 68.5%; AOR = 0.69, P = .11). Primary care visits rose for antidepressants (9.9% to 12.3%; AOR = 1.28, P = .01) and other anxiolytic/sedative-hypnotics (3.4% to 4.7%; AOR = 1.39, P = .01), but the largest growth was among benzodiazepines (5.6% to 8.7%; AOR = 1.62, P < .001). Among patients in primary care, increases primarily occurred among men, non-Hispanic white patients, and those with pain diagnoses as well as those with no mental health or pain diagnoses.

CONCLUSIONS

From 2003 to 2012, use of the most common psychotropic medications among older adults seen in primary care increased, with concentration among patients with no mental health or pain diagnosis. As the population of older adults grows and receives mental health treatment in primary care, it is critical to examine the appropriateness of psychotropic use.

Believing Jeny About Her Pain

A 19-year-old woman with cancer and excruciating pain was not easily responding to morphine. Some of the staff suspected that this pain was not physical, that it was all emotional. But when the palliative care team believed the young woman's report of her pain, they were able to arrive at the right combination of medicines to treat her pain, and to relieve her intolerable suffering.

Reliability and Validity of the Chinese Version of the Revised American Pain Society Patient Outcome Questionnaire in Postoperative Patients

The American Pain Society Patient Outcome Questionnaire and the subsequent revised version are the most frequently reported measures of the quality of pain management. However, the reliability and validity of the revised questionnaire have not been reported in Chinese patients. This study sought to evaluate the psychometric properties of the Chinese version of the revised questionnaire in postoperative patients in China. The study was a descriptive, cross-sectional psychometric study. The revised questionnaire was translated into Chinese according to international guidelines and then administered to participants. The patients' present, average, and worst pain intensity were evaluated in face-to-face interviews. The Pain Management Index was calculated according to the worst pain intensity and the classification of analgesic drugs used by the patients. The continuous items in the revised questionnaire demonstrated excellent construct validity and acceptable internal consistency reliability (0.732). Cronbach's alpha coefficients for the following subscales were acceptable: pain severity and sleep interference (0.773), activity interference (0.812), affective (0.824), and adverse effects (0.636); the exception was for the perception of pain care subscale (0.492). Patients with different anticipated pain management outcomes were differentiated as expected. Satisfaction could be predicted (31.3% of the variance) using subscales and items in the questionnaire. Although our evidence supports the psychometric properties of the Chinese version of the revised questionnaire when tested with postoperative patients, further study is needed, especially on the subscale perception of pain care.

An Assessment of the Impact of a Multipronged Approach to Reducing Problematic Pain Clinics in Florida

The present research evaluates recent changes to Florida law and policy to reduce problematic pain clinics (pill mills) and criminal diversion of prescription opioids. These changes entailed a multipronged effort linking regulatory and criminal-law approaches. Quantitative data from the Florida Department of Health and qualitative data from in-depth interviews with law-enforcement officers assigned to pill-mill taskforces reveal steep declines in pain clinics and pill mills. Respondents credit some regulatory enhancements for the reduction, although they describe some interagency cooperation problems and emphasize that despite success, many troublesome establishments continue to operate. The results suggest that Florida’s effort to reduce opioid diversion by tightening regulatory restrictions and law-enforcement scrutiny illustrates a multiagency approach to a problem spanning public health and criminal justice. This could be an example for other states seeking to combat problems that cannot be effectively addressed using regulatory or criminal law alone.

The impact of patient-reported outcome measures in clinical practice for pain: a systematic review

Purpose

Patient-reported outcome measures (PROMs) have increasingly been incorporated into clinical practice. Research suggests that PROMs could be viewed as active components of complex interventions and may affect the process and outcome of care. This systematic review examines PROMs in the context of treatment for non-malignant pain.

Methods

An electronic search on: MEDLINE, EMBASE, PsycINFO, PsycARTICLES, Cochrane Library and Web of Science identified relevant papers (February 2015). The inclusion criteria were: focused on implementing PROMs into clinical practice, adults, and primary data studies. Critical interpretive synthesis was used to synthesise qualitative and quantitative findings into a theoretical argument.

Results

Thirteen eligible studies were identified. Synthesis suggested that PROMs may be included in the initial consultation to assess patients and for shared decision-making regarding patient care. During the course of treatment, PROMs can be used to track progress, evaluate treatment, and change the course of care; using PROMs may also influence the therapeutic relationship. Post-treatment, using PROMs might directly influence other outcomes such as pain and patient satisfaction. However, although studies have investigated these areas, evidence is weak and inconclusive.

Conclusion

Due to the poor quality, lack of generalisability and heterogeneity of these studies, it is not possible to provide a comprehensive understanding of how PROMs may impact clinical treatment of non-malignant pain. The literature suggests that PROMs enable pain assessment, decision-making, the therapeutic relationship, evaluation of treatment and may influence outcomes. Further research is needed to provide better evidence as to whether PROMs do indeed have any effects on these domains.

Trends in major opioid analgesic consumption in Taiwan, 2002-2014

BACKGROUND/PURPOSE

According to WHO guideline, the consumption of opioids is an important sign of national progress in cancer pain relief. However, precise data on the consumption of opioid analgesics consumption in Taiwan has not been published. We investigate opioid analgesic consumption in Taiwan between 2002 and 2014 compare the results with those in other countries to see what we could learn about other methods of pain management. To find out the different patterns between Taiwan and other country, improves the quality of pain management.

METHODS

We extracted from the Controlled Drugs Management Information System (CDMIS) database, the consumption data of morphine, fentanyl, and pethidine, three strong opioids, and of codeine and buprenorphine, two weak ones. Data were presented as defined daily doses for statistical purposes per million inhabitants per day (S-DDD/m/d). The number of inhabitants was extracted from the Taiwan Ministry of Interior Statistics population database.

RESULTS

During the thirteen studied years, the total consumption of opioids markedly increased in Taiwan. By category, the consumption of morphine, fentanyl and buprenorphine increased, but the use of pethidine and codeine decreased. Compared with the selected regions and countries, the use of opioid in Taiwan progressed in Asia, but it was still lower than in Western countries.

CONCLUSION

Opioid analgesics are probable addictive; however, they can improve a patients' quality of life if properly used. The Taiwan FDA continuously introduces new opioid analgesics and educates physicians on how to use them correctly. These measures will improve the quality of pain management in Taiwan.

Towards improved decision support in the assessment and management of pain for people with dementia in hospital: a systematic meta-review and observational study

Background

Pain and dementia are common in older people, and impaired cognitive abilities make it difficult for them to communicate their pain. Pain, if poorly managed, impairs health and well-being. Accurate pain assessment in this vulnerable group is challenging for hospital staff, but essential for appropriate management. Robust methods for identifying, assessing and managing pain are needed.

Aims and objectives

Two studies were undertaken to inform the development of a decision support tool to aid hospital staff in the recognition, assessment and management of pain. The first was a meta-review of systematic reviews of observational pain assessment instruments with three objectives: (1) to identify the tools available to assess pain in adults with dementia; (2) to identify in which settings they were used and with what patient populations; and (3) to assess their reliability, validity and clinical utility. The second was a multisite observational study in hospitals with four objectives: (1) to identify information currently used by clinicians when detecting and managing pain in patients with dementia; (2) to explore existing processes for detecting and managing pain in these patients; (3) to identify the role (actual/potential) of carers in this process; and (4) to explore the organisational context in which health professionals operate. Findings also informed development of health economics data collection forms to evaluate the implementation of a new decision support intervention in hospitals.

Methods

For the meta-review of systematic reviews, 12 databases were searched. Reviews of observational pain assessment instruments that provided psychometric data were included. Papers were quality assessed and data combined using narrative synthesis. The observational study used an ethnographic approach in 11 wards in four UK hospitals. This included non-participant observation of 31 patients, audits of patient records, semistructured interviews with 52 staff and four carers, informal conversations with staff and carers and analysis of ward documents and policies. Thematic analysis of the data was undertaken by the project team.

Results

Data from eight systematic reviews including 28 tools were included in the meta-review. Most tools showed moderate to good reliability, but information about validity, feasibility and clinical utility was scarce. The observational study showed complex ward cultures and routines, with variations in time spent with patients, communication patterns and management practices. Carer involvement was rare. No pain decision support tools were observed in practice. Information about pain was elicited in different ways, at different times, by different health-care staff and recorded in separate documents. Individual staff made sense of patients’ pain by creating their own ‘overall picture’ from available information.

Limitations

Grey literature and non-English-language papers were excluded from the meta-review. Sample sizes in the observational study were smaller than planned owing to poor documentation of patients’ dementia diagnoses, gatekeeping by staff and difficulties in gaining consent/assent. Many patients had no or geographically distant carers, or a spouse who was too unwell and/or reluctant to participate.

Conclusions

No single observational pain scale was clearly superior to any other. The traditional linear concept of pain being assessed, treated and reassessed by single individuals did not ‘fit’ with clinical reality. A new approach enabling effective communication among patients, carers and staff, centralised recording of pain-related information, and an extended range of pain management interventions is proposed [Pain And Dementia Decision Support (PADDS)]. This was not tested with users, but a follow-on study aims to codesign PADDS with carers and clinicians, then introduce education on staff/patient/carer communications and use of PADDS within a structured implementation plan. PADDS will need to be tested in differing ward contexts.

Acute pain assessment tools: let us move beyond simple pain ratings

PURPOSE OF REVIEW

This review highlights challenges and current trends in tools used to assess acute pain across the lifespan.

RECENT FINDINGS

A plethora of similar assessment tools exist for acute pain, most focused on self-report of pain intensity. Attempts to improve the frequency and visibility of pain assessment by prompting pain as 'the fifth vital sign' resulted in unintended consequences, creating a pressing need for a conceptual shift to multidimensional assessment of acute pain.

SUMMARY

Valid and pragmatic assessment of pain is essential for effective pain management. Unidimensional scales that capture self-reported pain intensity ratings undervalue to the complexity of the pain experience. Pain is a biopsychosocial experience and assessment is a complex social transaction and an exchange of the meaning of pain that demands a more comprehensive approach.

Comprehensive care of pain: Developing systems and tools to improve patient care and resident education

Chronic non-cancer pain is a common condition associated with tremendous risk for morbidity and mortality. In many settings, the management of chronic non-cancer pain by primary care providers, although customary, can be difficult due to inadequate training and conflicts between patient expectations and best practices. Resident physicians, faculty, and staff of this family medicine residency program developed a comprehensive chronic pain management program to address these issues while improving patient outcomes. The program was aligned with evidence-based chronic non-cancer pain management strategies yet tailored to the needs of the providers and patients and the strengths of the clinic. In the end, the societal demand for improved chronic non-cancer pain management resulted in a massive curricular and clinical practice overhaul for this residency program.

Cranio-maxillofacial reconstruction with microvascular radialis flaps-parameters and correlations of postoperative pain management

OBJECTIVES

Postoperative pain management is of highest interest for patients undergoing maxillofacial surgery including microvascular reconstructive surgery. Currently, there is a lack of information regarding process and outcome of postoperative pain management after microvascular reconstruction.

MATERIALS AND METHODS

In a prospective clinical study, 31 adults were evaluated on the first postoperative day following microvascular reconstruction with a radial forearm flap using the standardized questionnaire of the Germany-wide project Quality Improvement in Postoperative Pain Management (QUIPS). It enables a standardized assessment of patients' characteristics, pain parameters, outcome and pain therapy process parameters.

RESULTS

Pain management consisted predominately of premedication with midazolam, sufentanil and metamizol intraoperatively, piritramid in the intensive care unit and metamizol, tramadol and fentanyl patches on ward. Nineteen patients (61.3 %) showed inadequate pain management with pain levels ≥4. Among other significant relations, patients exhibiting an age below the median presented significant higher levels of pain under strain (p = .041) and maximum pain (p = .006) as well as rate of breathing (p = .009) and mood (p = .006) disturbance. Performance of pain counselling showed specific impact on pain under strain (p = .008), maximum pain (p = .004) and satisfaction with pain intensity (p = .001). Whether microvascular reconstruction was performed with primary or secondary intention or performance of a neck dissection did not show significant influence.

CONCLUSIONS

QUIPS helped us to adequately evaluate the procedure-specific quality of postoperative management following microvascular reconstruction with a radial forearm flap. It helped us to identify a surprisingly high amount of inadequate pain management. Postoperative pain levels seem to be primarily influenced by the performed reconstruction.

CLINICAL RELEVANCE

Establishment of a continuous and procedure-specific evaluation of postoperative pain levels should help to avoid inadequate pain management, which is widely prevalent according to the literature and our study. Preoperative pain counselling is essential and should be procedure specific to be its best.

Thai Nurses' experiences of post-operative pain assessment and its' influence on pain management decisions

Background

While many studies have addressed various issues with regards to pain management, there is limited knowledge about how nurses assess pain in surgical wards. This study aimed to describe Thai nurses’ experiences of pain assessment in a surgical ward.

Methods

A cross-sectional explorative study was conducted. Participants were selected through theoretical sampling. Data was collected through interviews with twelve registered nurses working in surgical wards. Qualitative content analysis guided the analysis of the data.

Results

Nurses use a double/triple check system, communicated to the healthcare team via records and protocols, and they used their skills and experiences in pain assessment. The results showed that nurses missed the opportunity to include the patients’ self-reported pain in their accounts. Though much evidence of pain was collected, this did not seem to benefit the patients. Furthermore, the nurses were not using instruments to measure pain, which illustrates the potential unreliability of professionals who have differing opinions concerning the patients’ pain.

Conclusions

Thai nurses worked based on a ‘patient-evidence’ paradigm when assessing patients in pain; this should be shifted to an evidence-based paradigm. Furthermore, by including the patients’ self-reported pain in their assessment, nurses would both improve the quality of the pain assessment and empower patients in their pain management. Pain management practices in Thailand should be improved through education, training, supportive innovation, and collegial competence development in order to improve the quality of care in the post-operative field.

Routine screening for pain combined with a pain treatment protocol in head and neck cancer: a randomised controlled trial

BACKGROUND

We compared the effectiveness and cost of a pain screening and treatment program, with usual care in head and neck cancer patients with significant pain.

METHODS

Patients were screened for the presence of pain and then randomly assigned to either an intervention group, consisting of a pain treatment protocol and an education program, or to usual care. Primary outcome was change in the Pain Severity Index (PSI) over three months.

RESULTS

We screened 1074 patients of whom 156 were randomized to either intervention or usual care. Mean PSI was reduced over three months in both groups, with no significant difference between the two groups. The Pain Management Index (PMI) at three months, was significantly improved in the intervention group compared with usual care (P<0.001), as was Patient Satisfaction (mean difference in scores was statistically significant: -0.30 [-0.60 to -0.15]). All subjects reported clinically significant levels of anxiety and depression throughout the study. Treatment costs were significantly higher for intervention (mean=£400) compared with usual care (£200), with a low likelihood of being cost-effective.

CONCLUSIONS

There was no difference in the Pain Severity Index between the two groups. However there were significant improvements in the intervention group in patient satisfaction and PMI. The pain screening process itself was effective. Sufficient benefit was demonstrated as a result of the intervention to allow continued development of pain treatment pathways, rather than allowing pain treatment to be left to nonformalised ad hoc arrangements.

Morphine versus Hydromorphone: Does Choice of Opioid Influence Outcomes?

Morphine has traditionally been considered the first line agent for analgesia in hospitals; however, in the last few years there has been a shift towards the use of hydromorphone as a first line agent. We conducted a hospital population based observational study to evaluate the increasing use of hydromorphone over morphine in both medical and surgical populations. Additionally, we assessed the effect of this trend on three key outcomes, including adverse events, length of stay, and readmission rates. We evaluated data from the University Health Systems Consortium. Data from 38 hospitals from October 2010 to September 2013 was analyzed for patients treated with either hydromorphone or morphine. The use of morphine steadily decreased while use of hydromorphone increased in both medical and surgical groups. Rescue drugs were used more frequently in patients treated with hydromorphone in comparison to patients treated with morphine (p < 0.01). Patients receiving morphine tended to stay in the hospital for almost one day longer than patients receiving hydromorphone. However, 30-day all cause readmission rates were significantly higher in patients treated with hydromorphone (p < 0.01). Our study highlights that the choice of hydromorphone versus morphine may influence outcomes. There are implications related to resource utilization and these outcomes.

Pseudoaddiction: Fact or Fiction? An Investigation of the Medical Literature

Tremendous growth in opioid prescribing over two decades in the USA has correlated with proportional increases in diversion, addiction, and overdose deaths. Pseudoaddiction, a concept coined in 1989, has frequently been cited to indicate that under-treatment of pain, rather than addiction, is the more pressing and authentic clinical problem in opioid-seeking patients. This investigative review searched Medline articles containing the term "pseudoaddiction" to determine its footprint in the literature with a focus on how it has been characterized and empirically validated. By 2014, pseudoaddiction was discussed in 224 articles. Only 18 of these articles contributed to or questioned pseudoaddiction from an anecdotal or theoretical standpoint, and none empirically tested or confirmed its existence. Twelve of these articles, including all four that acknowledged pharmaceutical funding, were proponents of pseudoaddiction. These papers described pseudoaddiction as an iatrogenic disease resulting from withholding opioids for pain that can be diagnosed, prevented, and treated with more aggressive opioid treatment. In contrast, six articles, none with pharmaceutical support, questioned pseudoaddiction as a clinical construct. Empirical evidence supporting pseudoaddiction as a diagnosis distinct from addiction has not emerged. Nevertheless, the term has been accepted and proliferated in the literature as a justification for opioid therapy for non-terminal pain in patients who may appear to be addicted but should not, from the perspective of pseudoaddiction, be diagnosed with addiction. Future studies should examine whether acceptance of pseudoaddiction has complicated accurate pain assessment and treatment, and whether it has contributed to or reflected medical-cultural shifts that produced the iatrogenic opioid addiction epidemic.

The Quality of Pain Treatment in Community-Dwelling Persons with Dementia

BACKGROUND/AIMS

Despite pervasive and debilitating pain among elders, it is underassessed and undertreated; and cognitive impairment can add challenges. We assessed the quality of pain care for community-dwelling elderly patients with dementia.

METHODS

We phone interviewed 203 Veterans Affairs primary care outpatients with dementia and pain and reviewed medical records to score 15 quality indicators of pain assessment and management.

RESULTS

Pain assessment was documented for 98%, and a standard pain scale was used for 94%. Modified pain scales were rarely used. Though 70% self-reported pain of 'quite bad' or worse, charts documented no pain in 64%. When pain was identified, treatment was offered to 80%; but only 59% had a follow-up assessment within 6 months. Nonpharmacological interventions were underused.

CONCLUSION

Community-dwelling elders with dementia are underdiagnosed and undertreated for pain.

Management of Acute Postoperative Pain in Hand Surgery: A Systematic Review

PURPOSE

To conduct a systematic review to guide hand surgeons in an evidenced-based approach in managing postoperative pain.

METHODS

We performed a literature review for primary research articles on management of postoperative pain in hand surgery patients using Medical Literature Analysis and Retrieval System Online (MEDLINE; PubMed), Excerpta Medica database (EMBASE), and the Cochrane Collaboration Library. Inclusion criteria were primary journal articles examining treatment of acute postoperative pain based on any modality. Data related to pain assessment, postoperative recovery, and total postoperative analgesic consumption were extracted.

RESULTS

A total of 903 publications were reviewed; 184 publications underwent abstract review. After applying inclusion and exclusion criteria, 10 primary articles were selected for inclusion in this review. Data were noted to be heterogeneous and findings were compiled. Results were divided into groups evaluating postoperative pain medications or pain infusion catheters.

CONCLUSIONS

Although this review did not demonstrate a best practices model for postoperative pain management, it provides evidence for alternative medications and treatment strategies. The evidence available suggests that postoperative pain control should begin before surgery and that combining multiple strategies for pain treatment is beneficial. Given the increasing attention paid to narcotic prescriptions and the potential for abuse, surgeons should adopt evidence-based pain management practices. We provide an example algorithm for pain treatment in hand surgery based on available data and the authors' experience.

TYPE OF STUDY/LEVEL OF EVIDENCE

Palliative care in the ambulatory geriatric practice

Geriatrics and palliative care often overlap. This article focuses on 2 areas where the disciplines may differ in their approach. The first is planning for extreme illness and death, with explicit acknowledgment that limiting therapy might be a good idea. This situation is likely to have a different impact in the course of a routine geriatrics visit than in a palliative care context. The second is pain management, especially chronic pain. In patients with sharply limited life expectancy, the risk/benefit equation tilts easily toward narcotic use. In frail elders working to remain independent, the calculus may be quite different.

A comprehensive approach to address the prescription opioid epidemic in Washington State: milestones and lessons learned

An epidemic of morbidity and mortality has swept across the United States related to the use of prescription opioids for chronic noncancer pain. More than 100,000 people have died from unintentional overdose, making this one of the worst manmade epidemics in history. Much of health care delivery in the United States is regulated at the state level; therefore, both the cause and much of the cure for the opioid epidemic will come from state action. We detail the strong collaborations across executive health care agencies, and between those public agencies and practicing leaders in the pain field that have led to a substantial reversal of the epidemic in Washington State.

Pain assessment for people with dementia: a systematic review of systematic reviews of pain assessment tools

BACKGROUND

There is evidence of under-detection and poor management of pain in patients with dementia, in both long-term and acute care. Accurate assessment of pain in people with dementia is challenging and pain assessment tools have received considerable attention over the years, with an increasing number of tools made available. Systematic reviews on the evidence of their validity and utility mostly compare different sets of tools. This review of systematic reviews analyses and summarises evidence concerning the psychometric properties and clinical utility of pain assessment tools in adults with dementia or cognitive impairment.

METHODS

We searched for systematic reviews of pain assessment tools providing evidence of reliability, validity and clinical utility. Two reviewers independently assessed each review and extracted data from them, with a third reviewer mediating when consensus was not reached. Analysis of the data was carried out collaboratively. The reviews were synthesised using a narrative synthesis approach.

RESULTS

We retrieved 441 potentially eligible reviews, 23 met the criteria for inclusion and 8 provided data for extraction. Each review evaluated between 8 and 13 tools, in aggregate providing evidence on a total of 28 tools. The quality of the reviews varied and the reporting often lacked sufficient methodological detail for quality assessment. The 28 tools appear to have been studied in a variety of settings and with varied types of patients. The reviews identified several methodological limitations across the original studies. The lack of a 'gold standard' significantly hinders the evaluation of tools' validity. Most importantly, the samples were small providing limited evidence for use of any of the tools across settings or populations.

CONCLUSIONS

There are a considerable number of pain assessment tools available for use with the elderly cognitive impaired population. However there is limited evidence about their reliability, validity and clinical utility. On the basis of this review no one tool can be recommended given the existing evidence.

Survey of Primary-Care Providers on Perceived Benefits of and Barriers to PainTracker

Management of chronic pain is a common and complex challenge in primary care. Patient-reported outcomes surveys can help assist the patient with chronic pain to communicate the symptoms to their provider and engage the patient in treatment planning and evaluation to improve both quality of care and patient outcomes. A web survey was used to assess clinic providers' perceived ease of use, barriers to use, and clinical benefits of a patient-reported outcomes survey, termed PainTracker. More than half the respondents were satisfied with PainTracker and 76% of respondents agreed that PainTracker helps patients participate in their pain management. Although only a first step, this study helps evaluate the benefits of involving patients in their pain management care.

Documented electronic medical record-based pain intensity scores at a tertiary pediatric medical center: a cohort analysis

CONTEXT

Previous surveys have suggested that pain in hospitalized patients remains undertreated. However, little is known about those with persistently high pain scores.

OBJECTIVES

To document the distribution of scores and analyze the clinical characteristics of outliers with persistently high pain scores.

METHODS

With institutional review board approval, a retrospective cohort analysis of more than 1.5 million documented scores was completed in a tertiary pediatric medical center during a three-year period. Patients with persistently high pain scores were identified for subgroup analysis.

RESULTS

The median score was 0 (all years), and the means were 1.46, 1.34, and 1.3 in 2010, 2011, and 2012, respectively. Approximately 68% of admissions had at least one score of 4 or greater, although this level did not persist. Only 9% had mean scores of 4 or greater, and 1% (n = 492) had mean scores of 7 or greater. Scores remained high in patients within identifiable groups, that is, those with chronic pain (n = 311), sickle cell vaso-occlusive episodes (n = 52), and pain in children with developmental and neuromuscular disorders (n = 32). Few had persistently high scores with acute pain but without known comorbidities (n = 56).

CONCLUSION

Detailed review of clinical characteristics of patients with persistently high scores led to the strong impression that, in most cases, persistently high pain was not simply because of inadequate administration of opioids. Instead, the first step in improving pain management of hospitalized children may be the identification of outliers with high pain scores to direct efforts on the development of interventions for patient groups with mechanistically similar pain.

Integrating interdisciplinary pain management into primary care: development and implementation of a novel clinical program

OBJECTIVES

The aims of this study were to develop and implement an interdisciplinary pain program integrated in primary care to address stakeholder-identified gaps.

DESIGN

Program development and evaluation project utilizing a Plan-Do-Study-Act (PDSA) approach to address the identified problem of insufficient pain management resources within primary care.

SETTING

A large Healthcare System within the Veterans Health Administration, consisting of two academically affiliated medical centers and six community-based outpatients clinics.

METHODS

An interprofessional group of stakeholders participated in a Rapid Process Improvement Workshop (RPIW), a consensus-building process to identify systems-level gaps and feasible solutions and obtain buy-in. Changes were implemented in 2012, and in a 1-year follow-up, we examined indicators of engagement in specialty and multimodal pain care services as well as patient and provider satisfaction.

RESULTS

In response to identified barriers, RPIW participants proposed and outlined two readily implementable, interdisciplinary clinics embedded within primary care: 1) the Integrated Pain Clinic, providing in-depth assessment and triage to targeted resources; and 2) the Opioid Reassessment Clinic, providing assessment and structured monitoring of patients with evidence of safety, efficacy, or misuse problems with opioids. Implementation of these programs led to higher rates of engagement in specialty and multimodal pain care services; patients and providers reported satisfaction with these services.

CONCLUSIONS

Our PDSA cycle engaged an interprofessional group of stakeholders that recommended introduction of new systems-based interventions to better integrate pain resources into primary care to address reported barriers. Early data suggest improved outcomes; examination of additional outcomes is planned.

Increases in the use of prescription opioid analgesics and the lack of improvement in disability metrics among users

BACKGROUND AND OBJECTIVES

In the United States, use of oral opioid analgesics has been associated with increasing rates of addiction, abuse, and diversion. However, little is known about the recent national use of non-illicit prescription opioid analgesics (those prescribed in a physician-patient relationship), the primary source of these drugs for the general US population. Our primary objective was to examine trends in the use of prescription opioid analgesics in the United States and to identify defining characteristics of patient users of prescribed opioids from 2000 to 2010.

METHODS

We used the nationally representative Medical Expenditure Panel Survey to examine trends in prescription oral opioid analgesic use from 2000 to 2010. We used survey design methods to make national estimates of adults (18 years and older) who reported receiving an opioid analgesic prescription (referred to as opioid users) and used logistic regression to examine predictors of opioid analgesic use. Our primary outcome measures were national estimates of total users of prescription opioid analgesics and total number of prescriptions. Our secondary outcome was that of observing changes in the disability and health of the users.

RESULTS

The estimated total number of opioid analgesic prescriptions in the United States increased by 104%, from 43.8 million in 2000 to 89.2 million in 2010. In 2000, an estimated 7.4% (95% confidence interval, 6.9-7.9) of adult Americans were prescription opioid users compared with 11.8% (95% confidence interval, 11.2-12.4) in 2010. On the basis of estimates adjusted for changes in the general population, each year was associated with a 6% increase in the likelihood of receiving an opioid prescription from 2000 to 2010. Despite the apparent increase in use, there were no demonstrable improvements in the age- or sex-adjusted disability and health status measures of opioid users.

CONCLUSIONS

The use of prescription opioid analgesics among adult Americans has increased in recent years, and this increase does not seem to be associated with improvements in disability and health status among users. On a public health level, these data suggest that there may be an opportunity to reduce the prescribing of opioid analgesics without worsening of population health metrics.

Quality Assessment of Acute Inpatient Pain Management in an Academic Health Center

The quality of acute inpatient pain management remains suboptimal and poorly understood. In this retrospective study, we analyze acute pain management practice in a large academic health center using several quality indicators. Not surprisingly, despite high rate of pain assessment, many patients still have frequent, prolonged, and unrelieved severe pain episodes. Upon examination of naloxone administration, we identify potential inappropriate opioid prescription practices such as the use of wrong opioids in hepatic and renal failure and simultaneous use of multiple short-acting opioids. Most importantly, we find that chronic opioid users appear to suffer the most in terms of undertreatment of pain as well as opioid overdose, highlighting the urgent need to target this underserved population of patients.
