<title>Background</title>
There is limited information on how the barriers to interprofessional collaboration (IPC) across various professionals, organizations, and care facilities influence the health and welfare of older adults. This study aimed to describe the status of IPC practices among health and social workers providing care for older adults in the Philippines; investigate the perceived barriers to its implementation and perceived effects on geriatric care; and identify possible solutions to address the barriers limiting collaborative practice.

<title>Methods</title>
A case study approach was utilized employing 12 semi-structured in-depth interviews and 29 focus group discussions with care workers from selected primary health care units, public and private hospitals, and nursing homes that are directly involved in geriatric care delivery in two cities in the Philippines. Overall, 174 health and social workers consented to participate in this study. All interviews were audio-recorded and transcribed verbatim. An inductive thematic analysis using NVivo 12® was used to identify and categorize relevant thematic codes.

<title>Results</title>
Interprofessional geriatric care provided by health and social workers was observed to be currently limited to ad hoc communications typically addressing only administrative concerns. This limitation is imposed by a confluence of barriers such as personal values and beliefs, organizational resource constraints, and a silo system care culture which practitioners say negatively influences care delivery. This in turn results in inability of care providers to access adequate care information, as well as delays and renders inaccessible available care provided to vulnerable older adults. Uncoordinated care of older adults also led to reported inefficient duplication and overlap of interventions.

<title>Conclusion</title>
Geriatric care workers fear such barriers may aggravate the increasing unmet needs of older adults. In order to address these potential negative outcomes, establishing a clear and committed system of governance that includes IPC is perceived as necessary to install a cohesive service delivery mechanism and provide holistic care for older adults. Future studies are needed to measure the effects of identified barriers on the potential of IPC to facilitate an integrated health and social service delivery system for the improvement of quality of life of older adults in the Philippines.
