A comparison of outcomes among patients with schizophrenia in two mental health systems: a health state approach.

This paper introduces a health state modeling approach using clustering and Markov analysis to compare short- and long-term outcomes among health care populations. We provide a comparison to more conventional mixed effects regression methods and show that discrete state modeling offers a richer portrait of patient outcomes than the standard univariate techniques. We demonstrate our approach using primary data from a three year observational study of patients treated for schizophrenia at a VA Medical Center (VA) and in a Community Mental Health Center (CMHC) in the same urban community. Randomly selected samples of outpatients treated for schizophrenia or schizoaffective disorder were interviewed every six months using standardized psychiatric assessments such as the Positive and Negative Syndrome Scale (PANSS). Items from the PANSS were used to define 7 discrete health states representing different levels of severity and diverse mixtures of psychiatric symptoms. Conventional analysis showed that VA patients exhibited increasingly severe symptoms, while CMHC patients remained more stable over the study period. Health state analysis reinforced these results but also identified which subpopulations of VA patients were deteriorating. In particular they showed that there was little change over time among VA patients in the best and worst health states. Instead the deterioration was caused by VA patients with: a) mild symptoms and hallucinations and b) serious positive and negative symptoms, being more likely to enter a state with severe positive and negative symptoms accompanied by moderate general distress.

Oral health and systemic health.

Certain cancers, hypertension, diabetes, leukemia, gastrointestinal disorders, osteoporosis, and HIV and other infectious diseases can manifest themselves in the oral cavity. In addition, some of these conditions and the therapies for them can affect the teeth and mouth. This article outlines what physicians should know about how certain medical conditions and medications can affect dental health and treatment, how dentists can help detect underlying medical conditions, and how the two professions can better serve patients by working together. placement of implants, periodontal surgery, endodontic treatment, or subgingival manipulation. Physicians should be aware of potential complications from dental treatment, inform patients of the risks, and communicate to the patient's dentist about the patient's physical status, the extent to which his or her condition is under control, and how to prevent complications. The following examples illustrate the need for such interaction between physicians and dentists.
