Abstract
Clinical challenges exist in the management of hospitalized patients returning to the UK with potential Middle East respiratory syndrome coronavirus (MERS-CoV) infection, particularly with its clinical overlap with influenza, as demonstrated in this case-series and cost-analysis review of returning Hajj pilgrims. These patients were hospitalized with acute febrile respiratory illness, initially managed as potential MERS-CoV infections, but were eventually diagnosed with influenza. Additional costs were small, yet enhanced infection prevention measures created significant burdens on isolation rooms and staff time. Planning for predictable events such as Hajj is important for resource management. Here, in-house MERS-CoV diagnostic testing would have facilitated earlier diagnosis and discharge.

These costs were impossible to separate from the whole ward costs. The courier and testing of the patient sample for MERS-CoV (and other respiratory viruses) at the Birmingham reference laboratory was covered by PHE and was not a cost burden to our hospital. The cost of the in-house respiratory PCR testing was the same as for any patient presenting with a respiratory infection, not just one suspected of MERS-CoV infection.</p><p id="p0100">In terms of additional costs to the hospital, a set of single-use, enhanced PPE as compared to standard precautions cost an extra £2.50 per attendance, so up to £15 per day (data from NHS supplies), assuming six nursing staff entries and one doctor visit per day (<xref rid="tbl2" ref-type="table">Table II</xref>).</p><p id="p0105">The donning/doffing procedure required two staff (using a ‘buddy’ system) and was both laborious and time-consuming. Assuming an additional 15 min for staff to don, doff, dispose of PPE, and complete the logbook register, for up to six attendances or entries per day, this deprives the nurses and doctors of time in which they could perform other duties.</p><p id="p0110">For two nurses in a buddy system, this would then be 2 × £29.50 = £59 per patient, but only one of these nurses would use the enhanced PPE, giving a cost for six entries per day: 2 × £29.50 + £15.00 = £74. This time is doubled if two patients (e.g. a husband and wife) are admitted simultaneously, as we had in this case series, or if two nurses enter the patient room. This calculation is similar for the doctors (<xref rid="tbl2" ref-type="table">Table II</xref>).</p><p id="p0115">In addition, there is a one-off (once per year) enhanced PPE training course that each nurse/doctor is required to attend before being permitted to care for these patients (i.e. a one-off £29.50 additional cost for each nurse), though this cost contribution is difficult to estimate because it also serves as training to manage other high-risk patients such as those suspected or confirmed to be infected with a viral haemorrhagic fever (VHF) (<xref rid="tbl2" ref-type="table">Table II</xref>). So this one-off cost is not considered specifically as an extra cost due to a suspected MERS-CoV infection.</p></sec></sec><sec id="sec4"><title>Discussion</title><p id="p0120">Our experience is currently not rare in UK hospitals and highlights several important points.</p><p id="p0125">As with most assessments of returning Hajj pilgrims, none of our travellers actually had MERS-CoV, but were all managed as potential infections with strict isolation precautions until confirmed negative, even after an alternative diagnosis had been made.<xref rid="bib7" ref-type="bibr">7</xref>, <xref rid="bib8" ref-type="bibr">8</xref> A recent study, published by the same reference laboratory to which we send our samples for MERS testing, reported that out of the 202 patients tested during February 1<sup>st</sup>, 2013 to December 31<sup>st</sup>, 2015, none had laboratory-confirmed MERS-CoV infection. An alternative respiratory virus infection was diagnosed in half (50.3%) of the cases, including rhinoviruses, influenza A (H1N1 and H3N2), and influenza B, which were the most frequently detected. They found that peak testing occurred following the annual Hajj season and during other periods of increased national awareness.<xref rid="bib13" ref-type="bibr"><sup>13</sup></xref> The absence of any confirmed MERS-CoV-positive cases highlights the relevance and utility of the current study, but also highlights the need to encourage such pilgrims to increase their uptake of the seasonal influenza vaccine, as advised by one of their dedicated travel advice websites.<xref rid="bib14" ref-type="bibr"><sup>14</sup></xref></p><p id="p0130">However, with the increasing recognition that MERS-CoV causes a broader range of clinical illness, together with the potential for co-infection with other respiratory viruses leading to a delayed diagnosis of MERS-CoV, we felt that these patients justified the use of appropriate infection prevention measures until MERS-CoV infection had been excluded, as per published guidance.<xref rid="bib4" ref-type="bibr">4</xref>, <xref rid="bib5" ref-type="bibr">5</xref>, <xref rid="bib8" ref-type="bibr">8</xref>, <xref rid="bib14" ref-type="bibr">14</xref> Yet, the management of these patients using single, negative-pressure, isolation rooms, the limiting of staff interactions to essential duties with the use of enhanced PPE, and the secure transportation of laboratory specimens to an outside reference laboratory, posed significant resource and practical challenges in a busy hospital, particularly for patients (including one of ours) requiring intensive care.</p><p id="p0135">In-house laboratory respiratory panel testing yielded results within 30 h at the most (assuming a worst-case scenario of a sample just missing the daily run which takes 6 h to complete, and no assay failure) and detected influenza A or B viruses in all of our patients. However, transportation of samples to the reference laboratory, with their once-a-day MERS-CoV testing schedule, could potentially delay an exclusion of MERS-CoV by up to 24 h.</p><p id="p0140">The testing of MERS-CoV in-house would reduce this waiting time by up to 27 h (assuming same-day sample receipt and testing, which will take about 6 h for most commercial assays), and allow the downgrading of infection prevention procedures, as well as possible patient discharge on influenza treatment. However, this is dependent on the local laboratory results being as reliable. Outside of the Hajj season our hospital sees patients returning from MERS-CoV endemic areas far less frequently. Ensuring that local results are valid would therefore require the local laboratory to regularly undergo quality assurance processes, which would slightly negate the cost-benefits of earlier MERS-CoV exclusion. In addition, the shelf-life of any commercial kit will also impact on the final overall costs of running this MERS-CoV testing service in-house. Unused, outdated test kits would need to be discarded and replaced to cope with any traveller returning sporadically throughout the years from a MERS-CoV-endemic area, with a clinical presentation that would make them eligible for MERS-CoV testing.</p><p id="p0145">Our patients presented in early October 2015, ahead of the UK seasonal epidemic influenza activity. Thus, it is likely that their influenza viruses were acquired during Hajj from people who acquired their infection from other countries where influenza was already circulating, as has been previously described elsewhere.<xref rid="bib7" ref-type="bibr"><sup>7</sup></xref> Annual and, if possible, pre-travel influenza immunization of people attending Hajj pilgrimages may reduce their risk of influenza infection as is recommended on various websites, as well as by the Ministry of Health of Saudi Arabia.<xref rid="bib14" ref-type="bibr">14</xref>, <xref rid="bib15" ref-type="bibr">15</xref>, <xref rid="bib16" ref-type="bibr">16</xref></p><p id="p0150">Although other pilgrimages occur throughout the year, the Hajj is a global event, attracting pilgrims from all over the world for a relatively short duration; our patients all presented within a four-week period. In order to facilitate timely transfer of high-risk patients from the emergency department into appropriate isolation, we planned to keep at least one single negative-pressure cubicle vacant at all times. However, this policy became impracticable during busy periods of high bed occupancy.</p><p id="p0155">This case-series highlights the need to plan for predictable, yet potentially resource-challenging, events such as Hajj. In this particular situation, in-house MERS-CoV diagnostic testing would have facilitated earlier patient diagnosis with possible discharge, and a reduction in the level of PPE required, even if a longer inpatient stay were needed.</p></sec><sec id="sec5"><title>Conflict of interest statement</title><p id="p0160">None declared.</p></sec><sec id="sec6"><title>Funding sources</title><p
