For instance, patient surveys in both primary care and inpatient specialised care show that doctors sometimes fail to tell patients about the side effects of their medicines and warning-signs about their condition to watch out for. Based both on international comparisons and domestic patient surveys, the report identified inadequate care co-ordination as a weakness in Sweden’s health care system, particularly in relation to specific groups such as psychiatric patients and the sickest elderly. The barriers to co-ordinated care identified are reimbursement systems, vertical organisation of health care that makes it difficult to co-ordinate care processes horizontally, and lack of assistance for patients in negotiating their way through services involving multiple providers, as in care for patients with complex conditions or posthospital rehabilitation care.
