Medication safety in the home care setting: Development and piloting of a Critical Incident Reporting System / Medikationssicherheit im Home Care Bereich: Entwicklung und Pilotierung eines Critical Incident Reporting Systems

Background: While drug-related problems are among the most frequent adverse events in health care, little is known about their type and prevalence in home care in the current literature. The use of a Critical Incident Reporting System (CIRS), known as an economic and efficient tool to record medication errors for subsequent analysis, is widely implemented in inpatient care, but less established in ambulatory care. Recommendations on a possible format are scarce. A manual CIRS was developed based on the literature and subsequently piloted and implemented in a Swiss home care organization. Aim: The aim of this work was to implement a critical incident reporting system specifically for medication safety in home care. Results: The final CIRS form was well accepted among staff. Requiring limited resources, it allowed preliminary identification and trending of medication errors in home care. The most frequent error reports addressed medication preparation at the patients' home, encompassing the following errors: omission (30 %), wrong dose (17.5 %) and wrong time (15 %). The most frequent underlying causes were related to working conditions (37.9 %), lacking attention (68.2 %), time pressure (22.7 %) and interruptions by patients (9.1 %). Conclusions: A manual CIRS allowed efficient data collection and subsequent analysis of medication errors in order to plan future interventions for improvement of medication safety. The development of an electronic CIRS would allow a reduction of the expenditure of time regarding data collection and analysis. In addition, it would favour the development of a national CIRS network among home care institutions.

Medication-related problems during transfer from hospital to home care: baseline data from Switzerland.

Background The shift from inpatient to ambulatory care has resulted in an increase in home care patients. Little is known regarding medication safety associated with patient transfer from hospital to home care. Objective To evaluate medication-related problems in patients transferring from hospital to home care in Switzerland. Setting A non-for-profit home care organization in the city of Lucerne/Switzerland. Methods We conducted a prospective observational study, including patients aged ≥ 64 years and receiving ≥ 4 medications at hospital discharge. Two structured questionnaires assessing the transfer process were completed by home care nurses. Prescription quality was assessed using a PCNE Type 2b Medication Review. Main outcome measures The quality of the transfer process was measured comparing agreed-upon with reported parameters. Prescription quality was analyzed assessing the unambiguity of the prescription. Potentially inappropriate medications (Priscus® list), contraindications, duplications and interactions, and clinical pharmacist-identified potential medication-related problems were collected. Results Study patients (n = 100) received 8.6 ± 3.5 regularly administered medications. Only 5/100 patients had a complete set of written discharge information. At the time of the first visit, 13/100 patients had no written medication information available. Discharge medication prescriptions were clear to nurses in 62% of patients. In 20 patients, the required medications were unavailable, resulting in 19 medication errors. Assessment by a clinical pharmacist revealed only 33/100 patients had a clear discharge prescription. Of a total of 984 prescribed drugs, 16% were considered to be ambiguous, 22 (2.2%) were potentially inappropriate. 7/984 drugs were contraindicated, 8 were duplicates. Conclusion In addition to the known risk factors in patients transferring from hospital to home care (age, polymedication, multiple providers), 3 major problems impacted upon medication safety: fragmented communication, unreliable medication availability and a poor prescription quality. Clinical pharmacists are an important option to improve medication safety ass.
