Objective:
To study the feasibility of local infiltration in primary care consultations.
Design:
Before-and-after intervention study.
Setting:
Two clinics at an urban health centre.
Participants:
Patients diagnosed with pathology of tender areas and treated with corticosteroid infiltration between May 1997 and May 1998.
Intervention:
Corticoid infiltration plus local anaesthetic. Weekly check-up. Analysis of the variables: sex, age, diagnosis, time elapsed between indication and start of treatment, subjective assessment of pain before and after treatment (VRS scale), number of infiltrations per patient, side-effects. Evaluation of overall and individual effectiveness.
Results:
41 patients were infiltrated. Average age was 58. Most common pathologies were: rotary joint tendinitis (48.7%), anserine bursitis (24.4%), plantar fasciitis (7.3%). Average number of infiltrations per pathology: 1.3. Mean waiting time: 3.5 days. Comparison of pain by means of VRS (range 0-5) before and after treatment used the Wilcoxon test, with a statistically significant difference and p < 0.001 (z = -5.5109). For 35 patients (85.4%), pain was solved very well (values 0 and 1 on the VRS). For 3 patients (7.3%), improvement was moderate; and for 3 (7.3%) there was no improvement.
Conclusions:
1. Treatment with local infiltration of corticosteroids is effective in dealing with pain, and is an alternative to treatment with NSAIDs. 2. It is feasible in primary care, and there are many advantages if the general practitioner employs this therapeutic technique.
