ABSTRACT Health problems are prevalent in chemical dependency (CD) treatment populations, and often precede reductions in substance use among untreated populations. Few studies have examined whether medical problems predict better long-term outcomes in treated individuals, or how primary care utilization and CD/primary care service integration affects long-term outcomes among those with health problems.
In a sample of 598 CD patients in a private health plan, logistic regression models examined whether substance abuse-related medical conditions (SAMCs), integrated medical and CD care, and on-going primary care predicted remission of CD problems at 5 years.
Those with SAMCs were no more likely than others to be remitted at 5 years except among young adults and those with medical, but not psychiatric SAMCs. Higher levels of medical problem severity at intake and receiving integrated CD and primary care in the index treatment episode predicted remission in the full sample and among those with SAMCs. Among those with SAMCs, individuals with ongoing medical care - 2-10 primary care visits - in the 5 years following intake were more likely to be remitted at 5 years than those with fewer visits.
This study highlights the potentially important role of medical services in the long-term treatment of CD disorders. CD treatment may benefit from a disease management approach similar to that recommended for other chronic medical problems: specialty care when the condition is severe followed by services in primary care when the condition is stabilized.

    ABSTRACT: Abstract This study used a life-course perspective to identify and understand life events related to long-term alcohol and other drug (AOD) use trajectories across the life span. Using a purposive sample, we conducted semi-structured telephone interviews with 48 participants (n = 30 abstinent and 18 non-abstinent) from a longitudinal study of AOD outcomes 15 years following outpatient AOD treatment. A content analysis was conducted using ATLAS.ti software to identify events and salient themes. Caregiving for an ill or dependent family member was related to better AOD outcomes by reinforcing abstinence and reduced drinking, and contributing to alcohol cessation in most individuals who cited caregiving as a pivotal event. Grandparenting and parenting an adult child were motivational for sustaining abstinence and reduced drinking. Findings were mixed on death of a loved one, which was related to abstinence in some and relapse in others. Redemption and mutual fulfillment as caregivers, reconciliations with adult children, and legacy-building as grandparents were themes associated with maintaining abstinence and reduced drinking. AOD treatment has the opportunity to employ motivational interventions for relapse prevention that address the meaning and lifelong reach of intimate relationships for individuals and their AOD use across the life span.

    ABSTRACT: Abstract Despite long-standing recommendations that patients with substance use disorders (SUDs) receive primary care, only one-half of patients with SUDs receive such care. This article presents a conceptual model to facilitate the transition of patients from addiction treatment (AT) to primary care. A narrative review of the health care transition literature was conducted with an emphasis on identifying SUD-specific model elements. The resulting model is intended to guide AT and primary care providers and researchers in understanding factors that impact care coordination between AT and primary care and to provide an overview of evidence-based methods for supporting this care transition.

    ABSTRACT: Comments on the article "Joint principles: Integrating behavioral health care into the patient-centered medical home" (see record 2014-24217-011). The Patient-Centered Primary Care Collaborative, an organization representing a diverse group of stakeholders promoting primary care and the patient-centered medical home, strongly agrees that patients need a primary care system that better integrates behavioral and mental health. As the medical home model of care evolves in light of the scientific evidence, we must not lose sight of measuring what impacts patients and their families most-and patient-centered medical home (PCMH) recognition/certification programs should include the integration of mental and behavioral health if we are sincere in achieving the objectives.
