[Analysis of the therapy of chronic pain. A comparison of previous therapy and specialized pain therapy].
In Germany patients with chronic pain are often undertreated. It is necessary to establish more specialized institutions for pain therapy. As pain therapy is time consuming and labor intensive the costs must be justified by quality and efficiency. METHODS. We analyzed the new patients who came to our pain clinic in 1990 and compared the previous nonspecialist pain-related treatment with our pain therapy. For each patient we recorded the duration of pain therapy in the past, the number of physicians involved in the treatment, the number and duration of hospital stays and the number of operations carried out to relieve pain. For our pain therapy we recorded the number of treatments on an outpatient basis, the number of patients who were hospitalized and the number of hospital days. The outcome of our pain therapy was determined on a visual analogue scale (VAS). Pain relief of more than 50% was defined as adequate pain therapy. RESULTS. In 1990 we treated 379 new patients in our pain clinic. The largest group (140, 37%) had pain of the muscle or skeletal system. A further 75 patients (18%) had neuropathic pain, 66 (17%) suffered from cancer pain, several types of headache were found in 57 patients (15%), 19 patients (5%) had phantom limb pain, 11 (3%) suffered from reflex sympathetic dystrophy, and we diagnosed psychogenic pain in 11 patients (3%). On average the patients had been treated for their pain over a period of 10 years by eight different physicians. Patients suffering from migraine had the longest duration of preliminary therapy (19.2 years), while patients with cancer pain were pretreated for 2, 3 years in the period before. 80% (n = 302) of all patients were hospitalized at least once. A total of 20,959 hospital treatment days was registered. At least one operation was performed in 34% of the patients (n = 130) to relieve the pain. For all patients the pain relief afforded by the preliminary therapy was insufficient. In our pain therapy the patients had on average 6.5 outpatient appointments. We hospitalized 45 patients (12%), for a mean of 11 days. During the observation period 74% of the patients (n = 280) obtained pain relief of more than 50% in comparison with the start of treatment. CONCLUSION. The findings of our retrospective study demonstrate that specialized pain therapy is evidently effective. If such therapy is instituted early enough, chronic pain can be prevented. Shorter duration of disease, fewer stays in hospitals and less absence from work could reduce the economic costs of chronic pain. It is necessary to make specialised pain therapy a regular component of clinical practice; this means redoubling our efforts concerning education and experimental and clinical studies. The efficiency of pain therapy must be documented in order to improve the care of patients with chronic pain.
