Introduction: Although preventive health and therapeutics have benefited from advances in drug development and device innovation, translating these evidence-based treatments into real-world practice remains challenging. Aim: The current integrative review aims to identify facilitators and barriers and perceptions in delivering and managing injectable therapies from patient perspectives. Methods: An integrative review was conducted in the databases of PubMed, CINAHL, PsycINFO and Cochrane. Keywords were used “Injectable therapy”, “IV therapy”, “SC therapy”, “long term injectable therapies”, “self-administered injectable therapy”, “patients”, “caregivers”, “family”, “carers”, “facilitators”, “barriers”, “perspectives”, “needs”, “expectations”, “chronic disease”, “cardiovascular disease” linked with the words “OR” and “AND”. The search was limited from January 2000 to July 2019. Inclusion and exclusion criteria were used. Results: Twenty studies were identified from the literature search. Studies followed qualitative, quantitative methodology and mixed methods. Facilitators included: health improvement, prevention of disease complications, taking control of their disease, effectiveness of the medication and convenience in management. Barriers included: fear of needles, insulin will cause harm, poor perception of the benefits of injectable therapies on their quality of life, inconvenience in self-management, social stigma, impact on daily living, financial barriers, lack of education. Perceptions included: ‘treatment of last resort’, ‘life becomes less flexible’, ‘injectables were punishment/restriction’, ‘personal failure of self-management’. Conclusion: Evidence shows how to create effective communication and shared decision-making relationships to provide best possible care to patients who need injectable therapy and support for self-management. Future research might help guide response to the fears and barriers of the patients using patients’ perspectives.
