Patient-Reported Barriers to Accessing Surgical Care in Northern Vanuatu.

BACKGROUND: The Lancet Commission on Global Surgery proposed that population access to essential surgical care within 2 h is a core indicator of health system preparedness. Little evidence exists to characterise access to surgical care for island nations, including Vanuatu, a lower middle-income country in the Western Pacific. METHODS: A descriptive, facility-based, survey of surgical inpatients was undertaken over a 6-month period at Northern Provincial Hospital (NPH), Espiritu Santo, Vanuatu. This evaluated demographics, access to surgical care using the 'three delays' framework and clinical outcomes. RESULTS: A total of 121 participants were surveyed (60% of all surgical admissions), of which 31% required emergency surgery. Only 20% of emergency surgical cases accessed care within 2 h. There were no emergency cases from Torba or Malekula. The first delay (delay in seeking care) had the biggest impact on timely access. There was a geographic gradient to access, gender preponderance (males), and a delay in seeking surgical care due to a preference for traditional healers. CONCLUSION: There is urgent need to improve access to surgical care in Vanuatu, particularly for Torba and Malekula catchments. Demographic, geographic, sociocultural, and economic factors impact on timely access to surgical care within the northern regions of Vanuatu and support the notion that addressing access barriers is more complex than ensuring the availability of surgical resources. Future priorities should include efforts to reduce the first delay, address the role of traditional medicine, and review the geographic disparities in access.

Capturing nystagmus in the emergency room: posterior circulation stroke versus acute vestibular neuritis.

OBJECTIVES: To compare acute nystagmus characteristics of posterior circulation stroke (PCS) and acute vestibular neuritis (AVN) in the emergency room (ER) within 24 h of presentation. METHODS: ER-based video-nystagmography (VNG) was conducted, recording ictal nystagmus in 101 patients with PCS (on imaging) and 104 patients with AVN, diagnosed on accepted clinical and vestibular test criteria. RESULTS: Patients with stroke in the brainstem (38/101, affecting midbrain (n = 7), pons (n = 19), and medulla (n = 12)), cerebellum (31/101), both (15/101) or other locations (17/101) were recruited. Common PCS territories included posterior-inferior-cerebellar-artery (41/101), pontine perforators (18/101), multiple-territories (17/101) and anterior-inferior-cerebellar-artery (7/101). In PCS, 44/101 patients had no spontaneous nystagmus. Remaining PCS patients had primary position horizontal (44/101), vertical (8/101) and torsional (5/101) nystagmus. Horizontal nystagmus was 50% ipsiversive and 50% contraversive in lateralised PCS. Most PCS patients with horizontal nystagmus (28/44) had unidirectional "peripheral-appearing" nystagmus. 32/101 of PCS patients had gaze-evoked nystagmus. AVN affected the superior, inferior or both divisions of the vestibular nerve in 55/104, 4/104 and 45/104. Most (102/104) had primary position horizontal nystagmus; none had gaze-evoked nystagmus. Two inferior VN patients had contraversive torsional-downbeat nystagmus. Horizontal nystagmus with SPV ≥ 5.8 °/s separated AVN from PCS with sensitivity and specificity of 91.2% and 83.0%. Absent nystagmus, gaze-evoked nystagmus, and vertical-torsional nystagmus were highly specific for PCS (100%, 100% and 98.1%). CONCLUSION: Nystagmus is often absent in PCS and always present in AVN. Unidirectional 'peripheral-appearing' horizontal nystagmus can be seen in PCS. ER-based VNG nystagmus assessment could provide useful diagnostic information when separating PCS from AVN.
