Outpatient subcutaneous (s.c.) therapies are becoming more and more common in the treatmentof different diseases. The effectiveness of community-pharmacy-based interventions in preventingproblems that arise during s.c. self-injections of low-molecular-weight heparins (LMWH) is unknown. Our objective was to provide a standard operating procedure (SOP) for community pharmacists and to compare pharmaceutical vs. standard care in both clinical and daily life settings. We hypothesized that: pharmaceutical care results in improved adherence, safety, and satisfaction, and in fewer complications; the interventions used are feasible in daily life; and the resultsachieved in clinical and daily life settings are comparable. In the clinical setting (randomized controlledtrial), patients were recruited sequentially in hospital wards; in the daily life setting (quasi-experimental design with a comparison group), recruitment took place in community pharmacies by pharmacists and trained master students during their internship. Interventionswere offered according to patient needs. Data were collected by means of a monitored self-injectionat home and structured questionnaire-based telephone interviews at the beginning and theend of the LMWH treatment. The main outcome measures were: scores to assess patient’s skills; syringe count to assess adherence; and frequency, effectiveness, and patient’s assessment of received interventions. The results show a median age of the 139 patients of 54 years. Interventions resulted in improved application quality (p > 0.01) and knowledge (p = 0.03). Oral instructions were pivotal for improving patients’ application quality. We found no significant score differences between the intervention groups in the clinical and daily life settings. Patients’ baseline skills were high, with the lowest score being 0.86 (score range −2.00 to +2.00). Adherence rate was high (95.8%). In conclusion, our SOP for pharmacist interventions was of good quality, adequate, appreciated, and feasible in daily life. Patients are capable of managing s.c. injection therapies ifadequate assistance is provided.
