Abstract
To assess the burden of emergent illnesses and emergency care system usage by Yaoundé residents and to evaluate unmet needs for emergency care and associated barriers.
A cross-sectional study using a community-based survey.
Yaoundé, Cameroon.
All residents living in Yaoundé were selected as the target population to investigate the needs and usage of emergency care in Yaoundé. 14 households in every health area (47 in total) were selected using 2-stage sampling.
Unmet needs for emergency care.
Among the 3201 participants from 619 households who completed the survey, 1113 (34.8%) with median age of 22 experienced 1 or more emergency conditions in the previous year. Respondents who experienced emergency conditions used emergency units (7.0%), outpatient clinics (46.5%) or hospitalisation (13.0%), and in overall, 68.8% of them reported unmet needs for emergency care. The primary reasons for not seeking healthcare were economic issues (37.2%) and use of complementary medicine (22.2%). Young age (adjusted OR (95% CI) 1.80 (1.23 to 2.62)), rental housing (1.50 (1.11 to 2.03)) and moderate household income (0.60 (0.36 to 0.99)) were associated with unmet needs for emergency care.
Residents of Yaoundé had a high demand for emergency care, and high unmet needs were observed due to low emergency care usage. Development of a cost-effective, universal emergency care system is urgently needed in Cameroon.

However, the demands, usage and unmet needs for an emergency care system in Cameroon have not yet been assessed, and whether or not there are any barriers to accessing emergency care needs to be identified. The objectives of this study are to assess the burden of emergency illnesses and the demands and usage of emergency care by Yaoundé residents and to evaluate unmet needs within the past 1 year and barriers to emergency care access.</p></sec><sec sec-type="methods" id="s2"><title>Methods</title><sec id="s2a"><title>Study design and setting</title><p>This is a cross-sectional study using a community survey data performed in Yaoundé, Cameroon. The Republic of Cameroon is a LMIC located in Central Africa. Cameroon has an estimated population of 22.7 million with life expectancy of 55 years and median age of 18 years in 2014. Population growth rate was 2.6% and birth rate was 36.6 births per 1000 population. Gross national income per capita around $1360 using the Atlas method ($2400, purchasing power parity) and literacy rate was 75%.<xref rid="R12" ref-type="bibr">12</xref> Health expenditures were 4.1% of gross domestic product (GDP) and immunisation coverage rates among 1-year olds were 80–90%. Age-standardised mortality rates by communicable, non-communicable and injuries were 769, 675 and 106 per 100 000 population, respectively, and HIV/AIDS prevalence rate was 4.5%.<xref rid="R13" ref-type="bibr">13</xref> Subscriptions to landline phone and mobile phone were 4 and 71 per 100 inhabitants and internet users were 21% of the total population.<xref rid="R14" ref-type="bibr">14</xref></p><p>The capital city of Cameroon, Yaoundé with a population of ∼3.0 million, includes six health districts (Biyem Assi, Cité Verte, Djoungolo, Efoulan, Nkolbisson and Nkoldongo) with each health district providing coverage for between 4 and 12 health areas and their constituting communities.<xref rid="R14" ref-type="bibr">14</xref> There are currently 6 teaching hospitals, 6 district hospitals and 47 healthcare centres in Yaoundé. Among the five tertiary care centres, four have emergency units and three receive trauma patients.<xref rid="R15" ref-type="bibr">15</xref></p><p>The country uses the fee-for-service model to pay for medical care, and patients are required to supply necessary medications and supplies to the hospital after direct purchase in pharmacies. Health insurance programmes are poorly structured, and between 2010 and 2014, 94.2% of private expenditure on health was out-of-pocket expenditure.<xref rid="R12" ref-type="bibr">12</xref> The WHO estimates the density of physicians and nurses as 0.8 and 4.4 per 10 000 population, respectively.<xref rid="R13" ref-type="bibr">13</xref> Medical and nursing students graduate with little specialty training in emergency care due to lack of comprehensive curriculum in emergency medicine, which leaves emergency care providers difficult to evaluate and manage a broad spectrum of emergency conditions. For prehospital emergency care, the French Service d’Aide Médicale Urgente (SAMU) system is available in Yaoundé.<xref rid="R16" ref-type="bibr">16</xref> The SAMU is a prepaid system; however, usage of SAMU is very limited due to high cost, poor equipment and lack of trained healthcare professionals. There were a total of 11 functioning ambulances (2 for SAMU and 9 for hospitals) in Yaoundé and no working emergency phone number for prehospital emergency care.</p></sec><sec id="s2b"><title>Study population</title><p>All residents living in Yaoundé were the target population for the purpose of investigating the demands and usage of emergency care in Yaoundé. Study population included those who agreed to participate in this study and lived in Yaoundé during the study period. Incomplete household data and those with unknown information of age and gender were excluded.</p></sec><sec id="s2c"><title>Sample size and sampling</title><p>The target sample size was 658 households. Sample size was extrapolated using the expanded programme on immunisation cluster sampling method, which was established and initiated in 1974 by WHO to rapidly assess vaccination coverage and needs in developing countries.<xref rid="R17" ref-type="bibr">17</xref> A population parameter of 0.5 and design effect of 6 were used to allow for the design structure of this study, resulting in a required sample size of 576. We hypothesised a 10% non-response rate and aimed to select 14 households in every health area (47 in total), totalling 658 households.</p><p>Two-stage sampling was used to obtain a representative sample of the target population. First stage sampling was conducted to randomly select a town from each of the 47 health areas as a sampling cluster. From every selected community, 14 households were then selected as sampling units via convenience sampling.</p></sec><sec id="s2d"><title>Study protocols</title><p>Twenty surveyors composed of medical or nursing students were recruited from the Yaoundé 1 Medical School and Nursing School. All surveyors received a mandatory 2-day training prior to the survey. The surveyors were informed on the methodology of the survey as well as detailed procedures and instructions on how to conduct the survey.</p><p>Using a structured survey form and variable dictionary, face-to-face interviews were conducted from 11 to 15 December 2014 in the six health districts of Yaoundé. Twenty surveyors were divided into 10 teams of two, and each team was instructed to conduct face-to-face interviews in 14–21 households a day during the 5-day period. Surveyors were instructed to call the research team for consultation if they had any concerns or questions during the survey via their mobile phone.</p><p>We blocked the geographical survey town on the basis of street boarder on a commercial map. Recruitment of participants into the study living in the geographical survey area was based on a door-to-door approach at residential properties. At the centre of each sampled community, surveyors randomly selected a direction, and the most proximal house that lies in the chosen direction was selected to participate in the survey. From the first house, subsequent houses were selected by visiting the next available house. From each household selected, an adult over 19 years of age was asked to participate. There was no particular method of selecting a respondent; any adult in a family was able to participate regardless of his or her sociodemographic characteristics. Selected member of the household was informed of the study, and only those who provided written or oral consent was chosen as a respondent. One respondent per household was selected to provide information on behalf of the entire household and family members. Surveyors filled out the survey forms on behalf of the respondent. On completion, respondents were offered a gift (toothpaste or soap) for their time. The survey continued until at least 14 households were surveyed in each town.</p><p>To ensure the quality of data, all survey forms were collected by the research team at the end of the day and were subsequently entered into Microsoft Excel (Microsoft Corporation, Seattle, Washington, USA) on the following day after the survey by independent data entry contractors. Surveyors were immediately informed if the survey forms were incomplete or inaccurately filled in. For enhanced quality control, the research team randomly selected one surveyed community each day and revisited the houses to make sure the data were accurately collected.</p></sec><sec id="s2e"><title>Data collection and measurements</title><p>A structured survey form was designed to collect quantitative data. The questionnaire was composed of four sections: demographic information; socioeconomic information; healthcare usage for emergency conditions in the previous year; and unmet needs for severe and emergency conditions in the previous year.</p><p>Demographic information included age, gender, number of family members, and address, and socioeconomic information included language, education, occupation, household income, health insurance and residential information. For healthcare usage for emergency conditions, healthcare was defined as visits to outpatient clinic, emergency unit or hospitalisation. Emergency condition was defined by participant's judgement expressing that he or she had a condition severe enough to seek healthcare including immediate emergency care use. Conditions were categorised as neurological, cardiovascular, surgical, psychiatric, paediatric, obstetric, ophthalmological, trauma, haemorrhage, infection, intoxication/metabolic disorder, allergies, foreign body and other. In terms of unmet needs for emergency condition management, the primary reasons for not seeking healthcare were classified into seven categories: accessibility (long distance to hospital, or lack of transportation or hospital); affordability (economic issue); social and familial disapproval (family and/or friend's advice); distrust in hospital (do not think hospital care is effective); complementary medicine (self-medication, home care or traditional medicine); severity (personal judgement that the condition was not severe enough to visit hospital); and others.</p><p>A total of 34 questions were asked in closed-ended or open-ended questions. A pilot test was conducted that surveyors were given a survey guide with explanations and notes on every question. Based on the pilot test, it was anticipated that the survey will take ∼10–15 min to complete. Both the survey form and survey guide were initially developed in English and were subsequently translated into French by a translator in Cameroon.</p></sec><sec id="s2f"><title>Main outcomes</title><p>The primary end point of this study was demand of emergency care. The demand was defined as subjective conditions, in which participants felt as an emergency condition to be managed at once or within a short time period, which could be several hours or several days. The secondary outcome was unmet needs for emergency care; unmet needs were defined as non-usage of healthcare including emergency care services despite an individual's demand for emergency care due to emergency conditions. The tertiary end point was reasons for not seeking healthcare.</p></sec><sec id="s2g"><title>Statistical analysis</title><p>Descriptive analysis was performed to compare the distributions of demographic factors by demand (emergency conditions) and unmet needs, and statistically significant differences between the groups were analysed via Pearson's χ<sup>2</sup> test (categorical variables) and Wilcoxon rank-sum test (continuous variables). p Values were calculated based on a two-sided significance level of 0.05. Proportions of the reasons for not seeking healthcare were calculated.</p><p>Among those who experienced emergency conditions in the previous year, individual factors associated with unmet needs for emergency care were examined by calculating adjusted ORs (AORs) and 95% CIs using a multivariable logistic regression model. Stepwise selection methods were used with models that contain age and gender. All statistical analyses were performed using SAS software, V.9.4 (SAS institute, Cary, North Carolina, USA).</p></sec><sec id="s2h"><title>Ethical statements</title><p>Administrative authorisation was obtained from the regional delegate of Yaoundé and Division of Operation Research in Health at the Cameroon Ministry of Health (No. D30-168/L/MINISTANTE/SG/DROS/DTLC).</p></sec></sec><sec sec-type="results" id="s3"><title>Results</title><sec id="s3a"><title>Demographic findings of respondents</title><p>Among 667 households approached for the survey, 619 households (response rate 92.8%) with 3201 participants completed the surveys for all household members excluding those with unknown age or gender (n=26; <xref ref-type="fig" rid="BMJOPEN2016014573F1">figure 1</xref>).</p><fig id="BMJOPEN2016014573F1" orientation="portrait" position="float"><label>Figure 1</label><caption><p>Survey participants.</p></caption><graphic xlink:href="bmjopen2016014573f01"></graphic></fig><p>Of the 3201 survey respondents enrolled, 1113 (34.8%) experienced one or more emergency conditions in the previous year.

low usage and high unmet needs for emergency care in Yaoundé, Cameroon, using a community-based survey which provides a comprehensive, population-based estimation of demands for an emergency care system. Affordability and use of complementary medicine were primary factors for not seeking healthcare, and young age and low socioeconomic position were associated with unmet needs for emergency care. Assessment of demands, usage and unmet needs for emergency care is a basic step for developing an effective emergency care system and reducing preventable mortality and morbidity from time-sensitive illnesses and acute injuries. The demands and unmet needs identified in this study should be reflected on policy development and assurance of access to an emergency care system for the Cameroonians.</p><p>In sub-Saharan Africa, there are growing evidences showing that a full-capacity emergency facility or access to basic emergency care is associated with a significant reduction in in-hospital mortality.<xref rid="R1" ref-type="bibr">1</xref><xref rid="R7" ref-type="bibr">7</xref><xref rid="R8" ref-type="bibr">8</xref> However, total expenditure on health in Cameroon was only 5% of the GDP in the past 15 years, and emergency care system development is still in a nascent stage.<xref rid="R12" ref-type="bibr">12</xref><xref rid="R14" ref-type="bibr">14</xref> In this study, only 7.0% of respondents who experienced emergency conditions reported using emergency units, and the primary reason for not seeking healthcare was economic issue (37.2%). Furthermore, low socioeconomic positions such as low household income and rental housing were associated with unmet needs for emergency care. Life-threatening illnesses or injuries put individuals and families in a position to choose between financial burdens of medical care and risks of death or lifelong disability for missing out on healthcare. In order to provide timely and appropriate healthcare services to all, access to emergency care should be assured despite socioeconomic inequalities. Moreover, financial protection plans should be provided to protect urgent or life-threatening patients from high medical costs, which would ultimately improve usage of emergency care and enhance outcomes through universal emergency care.<xref rid="R1" ref-type="bibr">1</xref><xref rid="R2" ref-type="bibr">2</xref><xref rid="R9" ref-type="bibr">9</xref></p><p>Recent epidemiological studies suggest that the global burden of disease in LMIC is shifting away from infectious diseases towards time-sensitive illnesses and acute injuries such as ischaemic heart disease, cerebrovascular disease and unintentional injuries, which had been more commonly observed in higher income countries.<xref rid="R1" ref-type="bibr">1–5</xref><xref rid="R13" ref-type="bibr">13</xref><xref rid="R18" ref-type="bibr">18</xref> In this study, neurological emergency, intoxication and cardiovascular emergency were more frequently observed than infectious emergency conditions. Furthermore, younger populations in LMIC visited emergency facilities with severe injuries and high levels of critical illnesses;<xref rid="R19" ref-type="bibr">19</xref> median age of these populations with emergency conditions was 22 years. Currently, 45% of all deaths and 36% of disability-adjusted life-years in LMIC are caused by conditions amenable to secondary prevention, and therefore, strengthening of emergency care systems is essential to promote public health by providing appropriate care to time-sensitive diseases.<xref rid="R1" ref-type="bibr">1</xref><xref rid="R4" ref-type="bibr">4</xref><xref rid="R10" ref-type="bibr">10</xref></p><p>Prehospital care is one of the essential components of emergency care for increasing accessibility to emergency care.<xref rid="R4" ref-type="bibr">4</xref> Prehospital emergency care is rarely provided in LMIC including Cameroon, and the majority of critically ill patients and injury victims arrive at the hospital using a taxi or a private automobile.<xref rid="R4" ref-type="bibr">4</xref><xref rid="R20" ref-type="bibr">20</xref> Since a delay in life-saving procedures and lack of transportation could lead to avoidable mortality and morbidity, there is a significant need for transporting a patient from the location of an acute event incidence to a hospital by equipped ambulance and trained prehospital emergency care providers.<xref rid="R1" ref-type="bibr">1</xref><xref rid="R2" ref-type="bibr">2</xref><xref rid="R9" ref-type="bibr">9</xref><xref rid="R21" ref-type="bibr">21</xref></p><p>Lack of trained emergency care professionals and equipped facilities has been identified as a major obstacle to emergency care delivery in LMIC.<xref rid="R11" ref-type="bibr">11</xref><xref rid="R16" ref-type="bibr">16</xref> Previous studies reported that healthcare professionals in district hospitals had relatively poor skills for managing life-threatening conditions due to lack of specific training in emergency care and poorly equipped facilities.<xref rid="R16" ref-type="bibr">16</xref><xref rid="R19" ref-type="bibr">19</xref><xref rid="R21" ref-type="bibr">21</xref> As emergency care personnel are essential human resources for providing emergency care, a well-designed education programme is needed to train emergency care professionals with well-rounded competence in the diagnosis and treatment of emergency patients; be able to manage patients; effectively use emergency resources; cooperate with local communities; and develop and collaborate with prehospital emergency care system.<xref rid="R6" ref-type="bibr">6</xref></p><p>Use of self-medication, home care or traditional medicine was one of main reasons for not seeking healthcare and was especially high in patients with intoxication/metabolic disorder. Enhancement of usage of emergency care services by providing a universal high quality of emergency care and reducing the barriers to visit healthcare facilities could decrease the self-treatment without diagnosis and prescriptions by emergency care professionals.</p><p>An emergency care system is a critical component of the national health systems in LMIC.<xref rid="R9" ref-type="bibr">9</xref> An emergency care system needs to be well planned and supported throughout the continuum of care, from the occurrence of an acute medical event in a community to the provision of appropriate care at a destination hospital.<xref rid="R21" ref-type="bibr">21</xref> The Yaoundé National Emergency Center (Centre des Urgences de Yaoundé) opened in 2015 that could be one of cornerstones to provide universal emergency care to Cameroonians. In 2017, specialised training programmes for emergency care physicians and prehospital emergency care providers will be developed and implemented. We have been planning a follow-up study to evaluate the demands, usage and unmet needs for emergency care in 2017 and reassess them every 2 years in Yaoundé, Cameroon. Comprehensive assessment and continuous monitoring of demands, usage and unmet needs for emergency care would assist development of an evidence-based, effective emergency care system and health policies that incorporate Cameroonians' needs.</p><sec id="s4a"><title>Limitations</title><p>There are several limitations in this study. First, we used two-stage sampling methods to obtain a representative sample of residents in Yaoundé, Cameroon. The response rate (92.8%) was relatively high; however, these issues could have led to selection bias. Furthermore, the civil registration of births only covered 61% of all Cameroonians,<xref rid="R13" ref-type="bibr">13</xref> and information about the number of households in each community was not available. We did not calculate sampling weights and could not estimate prevalence of unmet needs for the whole target population. Second, we used face-to-face interview methods to survey demands, usage or unmet needs for emergency care. There is a possibility of misclassification by the respondents or interviewers and/or disagreement between interviewers for the categorisation of emergency conditions or reasons for not seeking healthcare, although a mandatory 2-day surveyor training programme and data quality control protocol were put in place. Third, the emergency condition and demands of emergency care were described with broad definitions and based on subjective judgements that involved the risk of summarising a variety of conditions and healthcare needs which might cause misclassification. Fourth, we used the classification of emergency conditions focusing to describe the scope of emergencies that impairs the differentiation of the severity and urgency of emergency conditions and the necessary healthcare resources. Fifth, survey responders answered for all household members for the previous year's emergency condition, which might cause memory bias. Sixth, resources and systems of emergency care services would differ by sociocultural context and limits generalisability of the study.</p></sec></sec><sec sec-type="conclusions" id="s5"><title>Conclusions</title><p>There was a high burden of emergency conditions, illnesses and acute injuries observed in Yaoundé, Cameroon. However, usage of emergency care was uncommon, and unmet needs for emergency care were very high. An overall improvement in accessibility to an emergency care system, affordability and a reasonable payment system for emergency care, efforts to train highly skilled personnel and enhanced life-saving capability may contribute to increased usage of the emergency care system and enhance public health.</p></sec></body><back><fn-group><fn><p><bold>Contributors:</bold> YSR and SDS had full access to all of the data in the study and take responsibility for the integrity of the data and the accuracy of the data analysis.
