Outcomes associated with opioid use in the treatment of chronic noncancer pain in older adults: a systematic review and meta-analysis.

This systematic review summarizes existing evidence regarding the efficacy, safety, and abuse and misuse potential of opioids as treatment for chronic noncancer pain in older adults. Multiple databases were searched to identify relevant studies published in English (1/1/80–7/1/09) with a mean study population age of 60 and older. Forty‐three articles were identified and retained for review (40 reported safety and efficacy data, the remaining 3 reported misuse or abuse outcome data). The weighted mean subject age was 64.1 (mean age range 60–73). Studies enrolled patients with osteoarthritis (70%), neuropathic pain (13%), and other pain‐producing disorders (17%). The mean duration of treatment studies was 4 weeks (range 1.5−156 weeks), and only five (12%) lasted longer than 12 weeks. In meta‐analyses, effect sizes were −0.557 (P<.001) for pain reduction, −0.432 (P<.001) for physical disability reduction, and 0.859 (P=.31) for improved sleep. The effect size for the Medical Outcomes Study 36‐item Health Survey was 0.191 (P=.17) for the physical component score and −0.220 (P=.04) for the mental component score. Adults aged 65 and older were as likely as those younger than 65 to benefit from treatment. Common adverse events included constipation (median frequency of occurrence 30%), nausea (28%), and dizziness (22%) and prompted opioid discontinuation in 25% of cases. Abuse and misuse behaviors were negatively associated with older age. In older adults with chronic pain and no significant comorbidity, short‐term use of opioids is associated with reduction in pain intensity and better physical functioning but poorer mental health functioning. The long‐term safety, efficacy, and abuse potential of this treatment practice in diverse populations of older persons remain to be determined.

Self‐Management Strategies to Reduce Pain and Improve Function among Older Adults in Community Settings: A Review of the Evidence

CONTEXT Self-management strategies for pain hold substantial promise as a means of reducing pain and improving function among older adults with chronic pain, but their use in this age group has not been well defined. OBJECTIVE To review the evidence regarding self-management interventions for pain due to musculoskeletal disorders among older adults. DESIGN We searched the Medline and Cumulative Index to Nursing and Allied Health Literature databases to identify relevant articles for review and analyzed English-language articles that presented outcome data on pain, function, and/or other relevant endpoints and evaluated programs/strategies that could be feasibly implemented in the community. Abstracted information included study sample characteristics, estimates of treatment effect, and other relevant outcomes when present. RESULTS Retained articles (N = 27) included those that evaluated programs sponsored by the Arthritis Foundation and other programs/strategies including yoga, massage therapy, Tai Chi, and music therapy. Positive outcomes were found in 96% of the studies. Proportionate change in pain scores ranged from an increase of 18% to a reduction of 85% (median = 23% reduction), whereas change in disability scores ranged from an increase of 2% to a reduction of 70% (median = 19% reduction). Generalizability issues identified included limited enrollment of ethnic minority elders, as well as non-ethnic elders aged 80 and above. CONCLUSIONS Our results suggest that a broad range of self-management programs may provide benefits for older adults with chronic pain. Research is needed to establish the efficacy of the programs in diverse age and ethnic groups of older adults and identify strategies that maximize program reach, retention, and methods to ensure continued use of the strategies over time.

Physical Therapists' Use of Cognitive-Behavioral Therapy for Older Adults With Chronic Pain : A Nationwide Survey

Background: Increasing evidence supports the use of cognitive-behavioral therapy (CBT) for patients with chronic pain. Objective: This study determined whether physical therapists incorporate CBT techniques (eg, relaxation, activity pacing) when treating older patients with chronic pain, ascertained their interest in and barriers to using CBT, and identified participant-related factors associated with interest in CBT. Design: This cross-sectional study used a telephone survey. Methods: One hundred fifty-two members of the Geriatrics and Orthopaedics sections of the American Physical Therapy Association completed the survey. Associations between participant-related factors and interest in CBT were assessed in statistical general linear models. Results: Commonly used CBT interventions included activity pacing and pleasurable activity scheduling, frequently used by 81% and 30% of the respondents, respectively. Non-CBT treatments included exercises focusing on joint stability (94%) and mobility (94%), and strengthening and stretching programs (91%). Respondents’ overall interest in CBT techniques was 12.70 (SD=3.4, scale range=5–20). Barriers to use of CBT included lack of knowledge of and skill in the techniques, reimbursement concerns, and time constraints. Practice type and the interaction of percentage of patients with pain and educational degree of the physical therapist were independently associated with provider interest in CBT in a general linear model that also included 6 other variables specified a priori. Limitations: Data are based on self-report without regard to treatment emphasis. Conclusions: Although only a minority of physical therapists reported use of some CBT techniques when treating older patients with chronic pain, their interest in incorporating these techniques into practice is substantial. Concerns with their skill level using the techniques, time constraints, and reimbursement constitute barriers to use of the interventions.

Characteristics of Older Adults Receiving Opioids in Primary Care: Treatment Duration and Outcomes

OBJECTIVE To describe characteristics of older adults who received opioids for chronic non-cancer pain (CP), ascertain types of opioid treatments received, and examine associations between patient characteristics and treatment outcomes. DESIGN Retrospective cohort study. SETTING Primary care practice in New York City. PATIENTS Eligible patients were >or=65 and newly started on an opioid for CP. OUTCOME MEASURES Patient characteristics and provider treatments, as well as duration of opioid therapy, proportion discontinuing therapy, and evidence of pain reduction and continued use of opioid for more than 1 year. Other outcomes included the presence and type(s) of side effects, abuse/misuse behaviors, and adverse events. RESULTS Participants (N = 133) had a mean age of 82 (range = 65-105), were mostly female (84%), and white (74%). Common indications for opioid treatment included back pain (37%) and osteoarthritis (35%). Mean duration of opioid use was 388 days (range = 0-1,880). Short-acting analgesics were most commonly prescribed. Physicians recorded side effects in 40% of cases. Opioids were discontinued in 48% of cases, mostly due to side effects/lack of efficacy. Pain reduction was documented in 66% of patient records, while 32% reported less pain and continued treatment for >or=1 year. Three percent displayed abuse/misuse behaviors, and 5% were hospitalized due to opioid-related adverse events. CONCLUSIONS Over 50% of older patients with CP tolerated treatment. Treatment was discontinued in 48% of cases, mostly due to side effects and lack of analgesic efficacy. Efforts are needed to establish the long-term safety and efficacy of opioid treatment for CP in diverse older patient populations.

Approach to and treatment of thyroid disorders in the elderly.

Thyroid gland dysfunction is prevalent in older adults and may be associated with significant morbidity if misdiagnosed and left untreated. Because of a decreased number of symptoms at presentation, an increased susceptibility to adverse events if not treated, and a greater likelihood of harm from treatment, the diagnosis and management of thyroid disorders in older adults can be challenging. This review focuses on the epidemiology, clinical presentation, risks and complications, and management of thyroid disorders in older adults, including hyperthyroidism, hypothyroidism, thyroid nodules, and thyroid cancer.

Tree-Based Model for Thyroid Cancer Prognostication

BACKGROUND Death is uncommon in thyroid cancer patients, and the factors important in predicting survival remain inadequately studied. The objective of this study was to assess prognostic effects of patient, tumor, and treatment factors and to determine prognostic groups for thyroid cancer survival. METHODS Using data from the Surveillance, Epidemiology, and End Results Program (SEER), we evaluated overall and disease-specific survival (DSS) in 43 392 well-differentiated thyroid cancer patients diagnosed from 1998 through 2005. Multivariable analyses were performed using Cox proportional hazards regression, survival trees, and random survival forest. Similar analyses were performed using National Cancer Data Base data, with overall survival (OS) evaluated in 131 484 thyroid cancer patients diagnosed from 1998 through 2005. Relative importance of factors important to survival was assessed based on the random survival forest analyses. RESULTS Using survival tree analyses, we identified 4 distinct prognostic groups based on DSS (P < .0001). The 5-year DSS of these prognostic groups was 100%, 98%, 91%, 64%, whereas the 10-year survival was 100%, 96%, 85%, and 50%. Based on random survival forest analyses, the most important factors for DSS were SEER stage and age at diagnosis. For OS, important prognostic factors were similar, except age at diagnosis demonstrated marked importance relative to SEER stage. Similar results for OS were found using National Cancer Data Base data. CONCLUSION This study identifies distinct prognostic groups for thyroid cancer and illustrates the importance of patient age to both disease-specific and OS. These findings have implications for patient education and thyroid cancer treatment.

Evaluating Positron Emission Tomography Use in Differentiated Thyroid Cancer.

BACKGROUND Using the Surveillance, Epidemiology, and End Results-Medicare database, a substantial increase was found in the use of positron emission tomography (PET) scans after 2004 in differentiated thyroid cancer (DTC) patients. The reason for the increased utilization of the PET scan was not clear based on available the data. Therefore, the indications for and outcomes of PET scans performed at an academic institution were evaluated. METHODS A retrospective cohort study was performed of DTC patients who underwent surgery at the University of Michigan Health System from 2006 to 2011. After identifying patients who underwent a PET scan, indications, rate of positive PET scans, and impact on management were evaluated. For positive scans, the location of disease was characterized, and presence of disease on other imaging was determined. RESULTS Of the 585 patients in the cohort, 111 (19%) patients had 200 PET scans performed for evaluation of DTC. Indications for PET scan included: elevated thyroglobulin and negative radioiodine scan in 52 scans (26.0%), thyroglobulin antibodies in 13 scans (6.5%), rising thyroglobulin in 18 scans (9.0%), evaluation of abnormality on other imaging in 22 scans (11.0%), evaluation of extent of disease in 33 scans (16.5%), follow-up of previous scan in 57 scans (28.5%), other indications in two scans (1.0%), and unclear indications in three scans (1.5%). The PET scan was positive in 124 studies (62.0%); positivity was identified in the thyroid bed on 25 scans, cervical or mediastinal lymph nodes on 105 scans, lung on 28 scans, bone on four scans, and other areas on 14 scans. Therapy following PET scan was surgery in 66 cases (33.0%), chemotherapy or radiation in 23 cases (11.5%), observation in 110 cases (55.0%), and palliative care in one case (0.5%). Disease was identifiable on other imaging in 66% of cases. PET scan results changed management in 59 cases (29.5%). CONCLUSIONS In this academic medical center, the PET scan was utilized in 19% of patients. Indications for the PET scan included conventional indications, such as elevated thyroglobulin with noniodine avid disease, and more controversial uses, such as evaluation of extent of disease or abnormalities on other imaging tests. PET scan results changed management in about 30% of cases.

New insights in risk stratification of differentiated thyroid cancer.

Purpose of review Numerous staging and scoring systems exist for differentiated thyroid cancer (DTC), but all harbor limitations. This has prompted investigation for new factors with prognostic implications for DTC. Recent findings Several new factors that may be involved in DTC risk stratification have emerged, such as thyroid stimulating hormone and molecular markers. In addition, others are controversial and being challenged, such as age, sex and lymph node involvement. Summary The purpose of this review is to present recent updates in the literature on new potential risk stratification predictors for DTC.

Population-Based Assessment of Complications following Surgery for Thyroid Cancer.

Context As thyroid cancer incidence rises, more patients undergo thyroid surgery. Although postoperative complication rates have been reported in single institution studies, population-based data are limited. Objective To determine thyroid cancer surgery complication rates and identify at-risk populations. Design/Setting/Patients Using the Surveillance, Epidemiology, and End Results-Medicare database, we evaluated general complications within 30 days and thyroid surgery-specific complications within 1 year in 27,912 patients who underwent surgery for differentiated or medullary thyroid cancer between 1998 and 2011. Multivariable analyses of patient characteristics associated with postoperative complications were performed. Main Outcome Measures General and thyroid surgery-specific complications. Results Overall, 1820 (6.5%) patients developed general postoperative complications and 3427 (12.3%) developed thyroid surgery-specific complications. In multivariable analyses, general and thyroid surgery-specific complications were significantly higher in patients >65 years [odds ratio (OR), 2.61; 95% confidence interval (CI), 2.31 to 2.95; OR, 3.12; 95% CI, 2.85 to 3.42], those with a Charlson/Deyo comorbidity score of 1 (OR, 2.40; 95% CI, 1.66 to 3.49; OR, 1.88; 95% CI, 1.53 to 2.31) and ≥2 (OR, 7.05; 95% CI, 5.33 to 9.56; OR, 3.62; 95% CI, 3.11 to 4.25), and those with regional (OR, 1.18; 95% CI, 1.03 to 1.35; OR, 1.31; 95% CI, 1.19 to 1.45) or distant disease (OR, 2.83; 95% CI, 2.30 to 3.47; OR, 1.85; 95% CI, 1.54 to 2.21), respectively. Conclusions The rates of thyroid cancer surgery complications are higher than predicted, and patients with older age, more comorbidities, and advanced disease are at greatest risk. Efforts to reduce complications are needed.

Skeletal Complications and Mortality in Thyroid Cancer: A Population-Based Study

Context Although bone is a common site for tumor metastases, the burden of bone events [bone metastases and skeletal-related events (SREs)] in patients with thyroid cancer is not well known. Objective To measure the prevalence of bone events and their impact on mortality in patients with thyroid cancer. Patients, Design, and Setting We identified patients diagnosed with thyroid cancer between 1991 and 2011 from the linked Surveillance Epidemiology and End Results-Medicare dataset. Multivariable logistic regression was used to identify the risk factors for bone metastases and SREs. We used Cox proportional hazards regressions to assess the impact of these events on mortality, after adjusting for patient and tumor characteristics. Results Of the 30,063 patients with thyroid cancer, 1173 (3.9%) developed bone metastases and 1661 patients (5.5%) developed an SRE. Compared with papillary thyroid cancer, the likelihood of developing bone metastases or an SRE was higher in follicular thyroid cancer [odds ratio (OR), 2.25; 95% confidence interval (CI), 1.85 to 2.74 and OR, 1.40; 95% CI, 1.15 to 1.68, respectively] and medullary thyroid cancer (OR, 2.16; 95% CI, 1.60 to 2.86 and OR, 1.62; 95% CI, 1.23 to 2.11, respectively). The occurrence of a bone event was associated with greater risk of overall and disease-specific mortality [hazard ratio (HR), 2.14; 95% CI, 1.94 to 2.36 and HR, 1.59; 95% CI, 1.48 to 1.71, respectively]. Bone events were a poor prognostic indicator even when compared with patients with other distant metastases (P < 0.001 and P < 0.001 for overall and disease-specific mortality, respectively). Conclusions Bone events in patients with thyroid cancer are a poor prognostic indicator. Patients with follicular and medullary thyroid cancers are at especially high risk for skeletal complications.
