Practice pointsr Amyotrophic lateral sclerosis patients are supported by models of patient-centered decision making delivered through specialized multidisciplinary clinics. r Advances in research have led to changes in service delivery, with new members added to the multidisciplinary team. r Developments in genetics research have increased the complexity of patients' choices for genetic testing. r User-designed decision support tools could improve communication between patients' families and clinicians, to negotiate this complex and ever-changing care.Developments in amyotrophic lateral sclerosis research and care delivery have created new arenas, and new dilemmas, for patients' decision making. This review explores three aspects of amyotrophic lateral sclerosis patient-centered care and decision making: patient-centered service delivery through the expanding multidisciplinary team; decision making for genetic testing and the implications of undergoing testing; and development of user-designed decision support tools to help patients and families make decisions as their choices become more complex. Until a cure is found, well-timed and effective decision making will rely on patient and family preferences to guide them through an increasingly complicated disease landscape. Amyotrophic lateral sclerosis (ALS) is a disease in search of a cure, or at least a highly effective treatment that will alleviate symptoms and slow disease progression. Until this can be achieved, people living with ALS, and their families, rely on healthcare services to help them manage their symptoms and maximize their quality of life as their needs increase. Best practice for people with ALS adopts a multidisciplinary approach of specialized care [1] that draws on patient-(or person-) centered principles and practices for cohesive and collaborative care [2].Patient-centered care, and the decision making that underpins it, have been defined, conceptualized and modeled many times [3][4][5][6][7]. In short, four principles [5] apply: affording people dignity, respect and compassion; offering coordinated care; offering personalized care; and enabling people to develop their unique range of capabilities to participate in their own care. Shared decision making, where patients and health professionals collaborate to arrive at a care decision, is considered best practice for patient-centered healthcare delivery [8]. Although preferences for sharing decision making vary with age, cultural background and disease setting [9][10][11], a majority of patients prefer to make their decisions using this approach [9]. Decision making for ALS care is often more complicated than for other degenerative conditions, as continual change in the patient's condition and circumstances mean that decision making is ongoing throughout the, frequently brief, course of the disease. Time frames for choosing and implementing a treatment may be short; and the number of health professionals to consult may be extensive; with multiple decisions under consideration at one time.
