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.

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.

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.
