Continuity of care in dual diagnosis treatment: definitions, applications, and implications.

OBJECTIVE: The goal of this work is to review the current literature on continuity of care in the treatment of people with dual diagnosis. In particular, this review set out to clarify how continuity of care has been defined, applied, and assessed in treatment and to enhance its application in both research and clinical practice. METHODS: To identify articles for review, the term "continuity" and combinations of "substance" and "treatment" were searched in electronic databases. The search was restricted to quantitative articles published in English after 1980. Papers were required to discuss "continuity" in treatment samples that included a proportion of patients with a dual diagnosis. RESULTS: A total of 18 non-randomized studies met the inclusion criteria. Analysis revealed six core types of continuity in this treatment context: continuity of relationship with provider(s), continuity across services, continuity through transfer, continuity as regularity and intensity of care, continuity as responsive to changing patient need, and successful linkage of the patient. Patient age, ethnicity, medical status, living status, and the type of mental health and/or substance use disorder influenced the continuity of care experienced in treatment. Some evidence suggested that achieving continuity of care was associated with positive patient and treatment-related outcomes. CONCLUSIONS: This review summarizes how continuity of care has been understood, applied, and assessed in the literature to date. Findings provide a platform for future researchers and service providers to implement and evaluate continuity of care in a consistent manner and to determine its significance in the treatment of people with a dual diagnosis.

Percutaneous insertion of Dual Growth Rods using a new mobile bearing implant

Growth rods are commonly used for the treatment of scoliosis in the immature spine. Many variations have been proposed but breakage of implants is a common problem. Growth rod insertion commonly involves large exposures at initial insertion followed by multiple smaller procedures for lengthening. We present our early experiences using a percutaneous technique of insertion of a new titanium mobile bearing implant (Medtronic Inc). The implant allows some rotatory motion in the middle of the construct thus reducing construct stresses and thus possibly reducing rod breakage risk. Based on this small initial series with 12 months follow-up, percutaneous insertion of growth rods using the new implant is a safe and reliable technique although the infection rate in our sample was of note. This may be related to the titanium wear and inflammation seen in the soft tissues at time of operation and visualised on histology. No implants have required removal due to infection, and all infections were treated with debridement at next lengthening and suppressive antibiotics. Propionibacterium is one of the commonest infections seen with spinal implants and sometimes does not respond to simple antibiotic suppression. The technique allows preservation of the soft tissues until definitive fusion is needed and may lead to a decrease in hospital stay. The implant is low profile and seems to offer advantages over other systems on the market. Further follow up is needed to look at longer term outcomes with this new implant type.
