The quality of electrodiagnostic tests for carpal tunnel syndrome: Implications for surgery, outcomes, and expenditures.
The quality of electrodiagnostic tests may influence treatment decisions, particularly regarding surgery, affecting health outcomes and health-care expenditures. In this study, the investigators evaluated test quality among 338 adults with workers' compensation claims for carpal tunnel syndrome. The investigators found that in simulations, suboptimal quality tests rendered surgery inappropriate for 99 of 309 patients (+32 percentage points). They also found that test quality was not associated with overall health, actual receipt of surgery, or expenditures.

Cervical dystonia incidence and diagnostic delay in a multiethnic population.
This study examined rates of diagnostic delay of cervical dystonia (CD) and the population of CD patients. Cases were identified from electronic medical records and multistage screening of more than 3 million Kaiser Permanente Northern California members from 2003-2007. CD incidence is greater in women and increases with age. About half of CD patients had a diagnostic delay. They were first given diagnoses of essential tremor, cervical disc disease, neck sprain/strain, anxiety and depression. Adverse effects are associated with diagnostic delay.
