Pharmaceutical care management: a modern approach to providing seamless and integrated health care.

Institutional pharmaceutical services have widely evolved over the past 20-30 years. Hospital pharmacy practice has changed from a profession concerned chiefly with the bulk preparation and distribution of drug products to one centred on ensuring optimal drug therapy. Whereas hospital pharmacists were charged with maintaining large drug stock on nursing units, many of them now provide individualized patient therapies. The practice of hospital pharmacy has therefore become one encompassing all aspects of drug therapy, from the procurement of drugs and drug delivery devices, their preparation and distribution, to their most appropriate selection and use for each patient. Hospital pharmacy services have traditionally had little involvement at the key stages in patients' hospital care. This leads to the conclusion that the model of clinical pharmacy practice adopted by many pharmacy department hospitals is no longer appropriate for the demands of today's health-care services. Reviews many new models proposed for clinical pharmacy practice including an integrated model for providing a pharmaceutical care management approach in the health-care system. This model is a response to the failures of traditional drug therapy. It is primarily an idea about how health professionals and patient should integrate their work to obtain outcomes important to patients and clinicians.
