[Opioids for noncancer pain in the elderly]

BACKGROUND

Opioids are increasingly used in the elderly. Side effects differ compared to other analgesics.

PURPOSE

In this review article, special aspects about using opioids for noncancer pain in older people and in geriatric patients are identified.

CURRENT SITUATION

So far randomized controlled trials for the indication of and comparison between various opioids have been performed in middle-aged patients and not exclusively in geriatric patients or elderly (> 75 years). Furthermore, the evidence for multimorbid elderly patients with respect to side effects is also very poor.

RECOMMENDATIONS

The indication for opioid therapy should be narrow. The patient and their caregivers must be provided patient information regarding opioid therapy. The principle "start low, go slow" is highly recommended. To reduce the risk of falls, longer acting opioids should be used and short acting opioids should be avoided. Everyday relevant negative effects on cognition are possible in opioid use and have to be observed. As recommended in the recently published German guideline for long-term use of opioids in noncancer pain a critical check after 3 months and in case of dosing over 120 mg morphine equivalents is advisable, especially for older patients. Liver and kidney function and drug interactions have to be taken into consideration like in every age group.

[Recommendations of the updated LONTS guidelines. Long-term opioid therapy for chronic noncancer pain]

BACKGROUND

The regular update of the German S3 guidelines on long-term opioid therapy for chronic noncancer pain (CNCP), the"LONTS" (AWMF registration number 145/003), began in November 2013.

METHODS

The guidelines were developed by 26 scientific societies and two patient self-help organisations under the coordination of the Deutsche Schmerzgesellschaft (German Pain Society). A systematic literature search in the Cochrane Central Register of Controlled Trials (CENTRAL), Medline and Scopus databases (up until October 2013) was performed. Levels of evidence were assigned according to the classification system of the Oxford Centre for Evidence-Based Medicine. The strength of the recommendations was established by multistep formal procedures, in order to reach a consensus according to German Association of the Medical Scientific Societies ("Arbeitsgemeinschaft der Wissenschaftlich Medizinischen Fachgesellschaften", AWMF) regulations. The guidelines were reviewed by the Drug Commission of the German Medical Association, the Austrian Pain Society and the Swiss Association for the Study of Pain.

RESULTS

Opioids are one drug-based treatment option for short- (4-12 weeks), intermediate- (13-25 weeks) and long-term (≥ 26 weeks) therapy of chronic osteoarthritis, diabetic polyneuropathy, postherpetic neuralgia and low back pain. Contraindications are primary headaches, as well as functional somatic syndromes and mental disorders with the (cardinal) symptom pain. For all other clinical presentations, a short- and long-term therapy with opioid-containing analgesics should be evaluated on an individual basis. Long-term therapy with opioid-containing analgesics is associated with relevant risks (sexual disorders, increased mortality).

CONCLUSION

Responsible application of opioid-containing analgesics requires consideration of possible indications and contraindications, as well as regular assessment of efficacy and adverse effects. Neither an uncritical increase in opioid application, nor the global rejection of opioid-containing analgesics is justified in patients with CNCP.

[Formative Evaluation of the "MBO® Kompakt-Neurowoche" - An Intensified Work-Related Rehabilitation Program for Neurological Patients]

Objectives: The MBO^® Kompakt-Neurowoche is offered as a work-related medical rehabilitation measure (based on allocation by a physician) following a regular neurological rehabilitation program with a duration of 7 days. Program access, process, and outcomes were examined in terms of a formative evaluation. Method: Pre-post-questionnaire data from 5 data points were used: start of regular rehabilitation (T0); start of work-related rehabilitation (T1); end of work-related rehabilitation (T2); 6-months follow-up (T3); 12-months follow-up (T4). Results: N=252 patients (75% male, 48±10 years) were included. Participants report a higher work-related treatment motivation and a more positive subjective return-to-work prognosis as compared to nonparticipants (N=215). At T4, 76% are (very) satisfied with the program. Patients rate therapy elements focusing on the assessment and improvement of work-related capacity and memory as especially useful. Assistance in developing job-related alternatives should be optimized. Conclusions: Patients participating in the work-related program report both vocational problems and a high motivation to deal with these problems during rehabilitation. The program is rated as useful with regard to return to work and the management of workplace issues.
