Medical emergencies at sea: an analysis of ambulance-supported and autonomously performed operations by lifeboat crews.

BACKGROUND: Very little data is available about the involvement of lifeboat crews in medical emergencies at sea. The aim of this study is to analyze the medical operations at sea performed by the Royal Netherlands Sea Rescue Institution (KNRM). METHODS: This is a retrospective descriptive analysis of all medical operations at sea performed by the KNRM between January 2017 and January 2020. The operations were divided in three groups: with ambulance crew aboard the lifeboat, ambulance crew on land waiting for the arrival of the lifeboat, and autonomous operations (without ambulance crew involvement). The main outcome measures were circumstances, encountered medical problems, follow-up and crew departure time. RESULTS: The KNRM performed 282 medical operations, involving 361 persons. Operations with ambulance crew aboard the lifeboat (n = 39; 42 persons) consisted mainly of persons with serious trauma or injuries; 32 persons (76.2%) were transported to a hospital. Operations with ambulance crew on land (n = 153; 188 persons) mainly consisted of situations where time was essential, such as persons who were still in the water, with risk of drowning (n = 45, 23.9%), on-going resuscitations (n = 9, 4.8%) or suicide attempts (n = 7, 3.7%). 101 persons (53,7%) were transported to a hospital. All persons involved in the autonomous operations (n = 90; 131 persons) had minor injuries. 38 persons (29%) needed additional medical care, mainly for (suspected) fractures or stitches. In 115 (40.8%) of all operations lifeboat crews did not know that there was a medical problem at the time of departure. Crew departure time in operations with ambulance crew aboard the lifeboat (13.7 min, min. 0, max. 25, SD 5.74 min.) was significantly longer than in operations with ambulance crew on land (7.7 min, min. 0, max 21, SD 4.82 min., p < 0.001). CONCLUSION: This study provides new information about the large variety of medical emergencies at sea and the way that lifeboat and ambulance crews are involved. Crew departure time in operations with ambulance crew aboard the lifeboat was significantly longer than in operations with ambulance crew on land. This study may provide useful indications for improvement of future medical operations at sea, such as triage, because in 40.8% of operations, it was not known at the time of departure that there was a medical problem.

Different characteristics of patients with gastro-oesophageal reflux disease on their path through healthcare: a population follow-up study.

BACKGROUND: Only a minority of patients with gastro-oesophageal reflux symptoms (GORS) seek medical advice. Little is known about patient characteristics associated with consultation in primary care and referral to secondary care. AIMS AND METHODS: We compared the characteristics of patients with GORS in the general population, those who consulted their general practitioner (GP) and those referred to secondary care for upper endoscopy. We aimed to identify differences between patients with short term (<90 days) and chronic symptoms, and differences between patients with symptoms in primary and secondary care. The study was performed in a primary care based prospective dynamic population. RESULTS: In total, 16% of 7237 adult patients were identified with GORS. Twenty-five percent of these patients consulted the GP, of whom 40% were referred for endoscopy. Patients with chronic GORS were older, had a higher body mass index, were more often referred for upper endoscopy (all P<0.001) and more frequently had relevant findings during endoscopy (oesophagitis: 50% and Barrett's oesophagus: 10%). Patients referred for upper endoscopy were older than nonreferred patients (P<0.001). CONCLUSION: Only a minority of people with GORS visit their GP. After consulting referral for endoscopy occurs relatively often. Underlying endoscopic abnormalities are frequently found in patients with chronic GORS.
