Diagnoses associated with the greatest years of potential life lost for in-hospital deaths in the United States, 1988-2010.

OBJECTIVE: Premature mortality is a public health concern that can be quantified as years of potential life lost (YPLL). Studying premature mortality from in-hospital mortality can help guide hospital initiatives and resource allocation. This paper identified the diagnosis categories associated with in-hospital deaths that account for the highest YPLL and their trends over time. STUDY DESIGN: Retrospective review of the Nationwide Inpatient Sample (NIS), 1988-2010. METHODS: Using the NIS, YPLL on patients hospitalized in the United States from 1988 to 2010 was calculated. Hospitalizations were categorized by related principal diagnoses using the Healthcare Cost and Utilization Project (HCUP) single-level Clinical Classification Software (CCS) definitions. RESULTS: Between 1988 and 2010, total in-hospital estimated mortality of 20,154,186 people accounted for 198,417,257 YPLL (9.84 YPLL per in-hospital mortality; 8,626,837 estimated annual mean YPLL). The ten highest YPLL diagnosis categories accounted for 51% of the overall YPLL. The liveborn disease category (i.e., in-hospital live births) was the most common principal diagnosis and accounted for the highest YPLL at 1,070,053. The septicemia category accounted for the second highest YPLL at 548,922. The highest in-hospital mortality rate (20.8%) was associated with adult respiratory failure/insufficiency/arrest. The highest estimated in-hospital annual mean deaths occurred in patients with pneumonia at 69,134. For all in-hospital mortality, the inflation adjusted total in-hospital charges per YPLL was highest for acute myocardial infarction at $9292 per YPLL. CONCLUSIONS: Using YPLL, a framework has been provided to compare the impact of premature in-hospital mortality from dissimilar diseases. The methodology and results may be used to help guide further investigation of hospital quality initiatives and resource allocation.

Resolution of trigeminal neuralgia after palliative embolization of a cerebellopontine angle arteriovenous malformation.

BACKGROUND: Trigeminal neuralgia (TN) is a syndrome with debilitating paroxysmal facial pain, one cause of which is thought to be vascular compression of the nerve root entry zone causing ephaptic transmission. Arteriovenous malformations (AVM) have been reported to cause TN, including AVMs in the cerebellopontine (CP) angle. These lesions have been successfully treated with endovascular coiling, ethylene-vinyl alcohol copolymer (Onyx) and surgery for decompression. CASE DESCRIPTION: We present a case of TN caused by AVM in the CP angle in a patient who was not a candidate for microsurgery and who did not want radiofrequency treatment or other destructive procedures because he would not tolerate facial numbness. The patient's symptoms were successfully treated by embolization using an ethylene-vinyl alcohol copolymer. After 17 months he had a recurrence of pain which was again treated with palliative embolization and again experienced resolution of his symptoms. CONCLUSION: This case demonstrates that palliative embolization is a safe and effective option for the treatment of trigeminal neuralgia pain in patients for whom surgery of the AVM is not an option.
