Relational continuity of care in community pharmacy: A systematic review

Relational continuity of care (COC) is becoming an important concept related to improving healthcare quality, reducing medical costs and increasing patient satisfaction with primary care. While community pharmacy (CP) has a considerable role in primary care, there are few reports dedicated to the role of relational COC in CP. This study reviewed the existing evidence of relational COC in CP and its effect on patients. PubMed, Embase, CINAHL, Cochrane Library CENTRAL and Google Scholar were used to search for relevant studies from the date of database inception through to January 2021, which were appraised according to eligibility criteria. There were no limitations on the primary outcome or language. Case reports and studies without control groups were excluded. The Newcastle-Ottawa quality assessment scale was used to assess the quality of the studies. Database searches identified 13 records. Relational COC measures in the included studies were grouped in three kinds; pharmacy-visiting pattern, Continuity of Care Index and loyalty. The assessed outcomes were medication adherence behaviour (e.g., the proportion of days covered, medication possession ratio), adverse drug reactions, potentially inappropriate drug prescribing and clinical outcomes. The odds of patients adhering to their medication regimen were about 1.1~2.5 times higher among those who consistently visited a single pharmacy compared to patients visiting multiple pharmacies. Additionally, the care provision with a high level of relational continuity could lower inappropriate drug use by 21~32 per cent and the use of other costly services by 12~29 per cent. This study suggests that a high degree of relational COC in CP could improve safe use of medications among patients. Future research is needed to employ more rigorous methods to reduce heterogeneity and to measure effects on clinical outcomes.
