It is responsible for nearly one million hospitalizations each year globally with rising rates. Despite therapeutic advances, it is associated with poor prognosis. Therefore, his study aimed to assess in-hospital mortality and its associated factors among adult acute heart failure patients in a tertiary hospital, Harar, Eastern Ethiopia.  Methods: A hospital-based retrospective cross-sectional study was employed among 454 adult acute heart failure patients treated in the medical ward of Haramaya University Hiwot Fana Comprehensive Specialized Hospital from June 01, 2016 to May 31, 2021. Data was collected using structured data abstraction format from July 15 to August 14, 2021. Collected data was entered to Epi-Data version 3.1, exported to and analyzed using Statistical Package for Social Science (SPSS) version 21.0. Bivariate and multivariate logistic regression was used to identify factors associated with in-hospital mortality. Results: A total of 454 acute heart failure patient’s medical records were reviewed. More than half, 282 (62.1%) of patients were females. The median age of patients was 45 years (± 28 IQR). In-hospital mortality was 18.9% and it was more prevalent in the first week of admission, 61 (70.9%). Sex (female) (Adjusted Odds Ratio (AOR)=2.83, p=0.001)), having smoking history (AOR=2.51, p=0.031), generalized body swelling (AOR=2.67, p=0.001), hypotension (AOR=4.56, p=0.001) and tachycardia (AOR=4.57, p=0.000) were factors associated with in-hospital mortality. Conclusion: In-hospital mortality is found to be very high among acute heart failure adult patients. Therefore, dedicated programs need to be developed to reduce mortality from acute heart failure and further prospective studies should be conducted to investigate the problem in-depth."> <meta

HF is caused by a structural and/or functional cardiac abnormality, resulting in reduced and/ or elevated intra-cardiac pressure. This pressure impairs the ability of the heart to fill with blood at normal pressure or eject blood adequate to fulfill the needs of the metabolizing organs. HF remains a major cause of mortality and <a target='_blank' href='https://www.openaccessjournals.com/peer-reviewed-articles/morbidity-12546.html'>morbidity</a> [<a href="#2" title="2">2</a>-<a href="#4" title="4">4</a>].</p> <p>AHF is defined as a gradual or rapid change in heart failure syndromes, which poses a unique diagnostic and management challenge and requires urgent therapy [<a href="#5" title="5">5</a>]. AHF also covers a wide range of the spectrum, which ranges from mild exacerbations with gradual increases in edema to cardiogenic shock [<a href="#6" title="6">6</a>]. These symptoms in AHF are the result of severe pulmonary congestion due to reduced left ventricular filling pressures with or without low cardiac output [<a href="#7" title="7">7</a>].</p> <p>AHF is responsible for nearly one million hospitalizations each year with rising rates and after initial hospitalization, 25% of patients are readmitted at 30 days, 35% of which are due to a new exacerbation [<a href="#8" title="8">8</a>]. In Africa, 7% to 10% of all medical admissions to hospitals are due to <a target='_blank' href='https://www.openaccessjournals.com/peer-reviewed-articles/cardiovascular-14501.html'>cardiovascular</a> disease, with <a target='_blank' href='https://www.openaccessjournals.com/peer-reviewed-articles/heart-failure-3893.html'>heart failure</a> contributing to 3% to 7% [<a href="#9" title="9">9</a>]. There were no data on the prevalence of heart failure in the general population in Ethiopia. A study in single setting at Dabat district, northwest Ethiopia, revealed that out of 216,420 populations 32.2% had heart disease. Hospitalization due to AHF is associated with several factors and comorbidities like older age, female gender, hyperuricemia, obesity, atrial fibrillation, peripheral artery disease and chronic <a target='_blank' href='https://www.openaccessjournals.com/peer-reviewed-articles/kidney-disease-220.html'>kidney disease</a> [<a href="#10" title="10">10</a>].</p> <p>Once diagnosed, AHF patients may be classified using different methods based on presentation. Depending on whether patients have a <a target='_blank' href='https://www.openaccessjournals.com/peer-reviewed-articles/history-8486.html'>history</a> of HF or not, it is classified as ADHF which occurs in patients with <a target='_blank' href='https://www.openaccessjournals.com/peer-reviewed-articles/heart-failure-3893.html'>heart failure</a> <a target='_blank' href='https://www.openaccessjournals.com/peer-reviewed-articles/history-8486.html'>history</a> and <em>de novo</em> AHF that occurs in individuals with no <a target='_blank' href='https://www.openaccessjournals.com/peer-reviewed-articles/history-8486.html'>history</a> of heart failure”. Based on SBP at presentation, AHF is classified as “hypertensive AHF (SBP>140 mmHg), normotensive AHF (SBP is between 90-140 mmHg) and hypotensive AHF (SBP<90 mmHg)”. Depending on the hemodynamic condition of the patients, it is classified as “warm and dry (well-perfused without congestion), warm and wet (wellperfused but congested), cold and dry (hypo-perfusion without congestion) and cold and wet (hypo-perfusion and congestion)”. Based on Left Ventricular Ejection Fraction (LVEF), AHF is classified as “AHF with reduced ejection fraction and AHF with preserved ejection fraction” [<a href="#11" title="11">11</a>].</p> <p>Depending on congestive and organ perfusion status the management approaches of AHF involves relief of symptoms, restoration of systemic tissue perfusion via improved cardiac output and minimization of further cardiac damage. These can be attained by using diuretics, neuro-hormonal antagonists and inotropes [<a href="#12" title="12">12</a>,<a href="#13" title="13">13</a>]. Despite therapeutic advances, the prognosis of AHF is poor and re-hospitalization is high which is 25% to 30% [<a href="#14" title="14">14</a>]. HF in general is associated with a huge economic burden which the overall cost is estimated at $108 billion globally and $28 million in Ethiopia per annum [<a href="#15" title="15">15</a>].</p> <p>The burden of AHF is high in resource-limited countries where patient’s low levels of <a target='_blank' href='https://www.openaccessjournals.com/peer-reviewed-articles/education-15078.html'>education</a> and income also contribute [<a href="#16" title="16">16</a>]. In sub-Saharan Africa, many of the equipment and <a target='_blank' href='https://www.openaccessjournals.com/peer-reviewed-articles/drugs-2383.html'>drugs</a> commonly used to diagnose and treat AHF in resource-rich settings are lacking [<a href="#17" title="17">17</a>,<a href="#18" title="18">18</a>]. In Ethiopia, in addition to this lack of equipment and drugs, knowledge about <a target='_blank' href='https://www.openaccessjournals.com/peer-reviewed-articles/cardiovascular-14501.html'>cardiovascular</a> risk factors is at suboptimal levels (46%) and AHF patients are of middle age this is an additional burden due to the impact on productivity [<a href="#19" title="19">19</a>-<a href="#21" title="21">21</a>].</p> <p>Regarding in-hospital mortality from AHF, it is 1.5% to 5.3% in developed countries [<a href="#22" title="22">22</a>-<a href="#24" title="24">24</a>]. However, it is very high in Ethiopia (17.2% to 24.4%) [<a href="#25" title="25">25</a>]. One single setting study showed a high burden of the HF (32.2% of the population had heart disease) and household food insecurity was among factors associated with the non-communicable disease which include heart disease, HF is the third most common reason for immediate admissions, with a prevalence of 16.0% among patients admitted to medical wards [<a href="#26" title="26">26</a>,<a href="#27" title="27">27</a>].</p> <p>Throughout the country, hospital-based studies on AHF that look into in-hospital mortality of the disease and its associated factors are scarce and are lacking in this study setting. Therefore, this study aimed to assess in-hospital mortality and its associated factors among adult patients with acute <a target='_blank' href='https://www.openaccessjournals.com/peer-reviewed-articles/heart-failure-3893.html'>heart failure</a> Fana Comprehensive Specialized Hospital from 15 July to 14 August 2021, Harar, Ethiopia.</p> <p>This study provides insights regarding in-hospital mortality of AHF and its associated factors among adult patients. Therefore, primarily it encourages hospital managers and each health professionals who participate in patient care to take measure in the spirit of improving the treatment outcome of AHF by forwarding necessary recommendations for possible changes and to scale up current standard of care in HFSCH and other similar hospitals. This study is also a stepping-stone for the study setting to alarm other researchers to investigate the problem in-depth throughout the country. Furthermore, the finding of this study can be used as input for development of treatment guidelines need to be modified for the future at the national level.</p> <h3>Materials and Methods</h3> <p><strong><em>Study design, setting and period</em></strong></p> <p>The retrospective cross-sectional study was conducted from July 15 to August 14, 2021 at HFCSH, Eastern Ethiopia. HFCSH is a specialized hospital in Eastern Ethiopia, which is found in Harar town, 526 km from Addis Ababa, the capital city of Ethiopia. It is serving as a referral hospital for the entire eastern part of the country including Eastern Oromia, Dire Dawa city administration, Harari and Somali regional states. There are different wards and clinics within the hospital that provide services for the community such as medical ward, pediatric ward, <a target='_blank' href='https://www.openaccessjournals.com/peer-reviewed-articles/surgery-923.html'>surgery</a> ward, gynecologic and obstetrics ward, <a target='_blank' href='https://www.openaccessjournals.com/peer-reviewed-articles/oncology-4576.html'>oncology</a> ward, antenatal clinic, dental clinic, a <a target='_blank' href='https://www.openaccessjournals.com/peer-reviewed-articles/tuberculosis-2706.html'>tuberculosis</a> clinic, ante-retroviral therapy clinic, dermatology clinic and ophthalmologic clinic. The medical ward has 22 beds.</p> <p><strong><em>Population</em></strong></p> <p>All adult patients with a diagnosis of AHF treated at HFCSH were source population. All adult patients with a diagnosis of AHF treated at HFCSH in the past five years (from June 01, 2016 to May 31, 2021) who fulfilled the inclusion criteria were the study population.</p> <p><strong><em>Eligibility criteria</em></strong></p> <p>All adult patients whose was age less than 18 years with a confirmed diagnosis of AHF and treated during the data retrieval period at the medical ward of HFCSH were included in this study. However, all patients with unknown outcome (referred or disappeared) and lost and/or incomplete patients’ medical records were excluded from the study.</p> <p><strong><em>Sample size determination</em></strong></p> <p>For the first two objectives sample size of the study was calculated using single population proportion formula by considering the following assumptions: Prevalence of in-hospital mortality (p)=17.2% taken from another similar study, Confidence Level (CI)=95% and corresponding Z score of 1.96, margin of error (W)=5%.</p> <p>Thus sample size was, n=(Zα/2)2 p (1-p)/w2=(1.96)2*0.172*0.828/ (0.05)2=218.8. For the objective of factors associated with inhospital mortality sample size was calculated using Epi-Info version 7.2.4.0 (<strong>Table 1</strong>).</p> <div class="table-responsive"> <table class="table table-no-border"> <thead> <tr> <th colspan="6">Determinants of treatment outcome </th> </tr> <tr> <th>Factors </th> <th>Assumptions </th> <th>% Exposed </th> <th>% Unexposed </th> <th>Reference </th> <th>Sample size (N) </th> </tr> </thead> <tbody> <tr> <td>Smoking </td> <td>CI: 95% Power:80% Ratio:1:1 </td> <td>44.4 </td> <td>15.6 </td> <td>-20 </td> <td>80 </td> </tr> <tr> <td>Diabetes mellitus </td> <td>CI: 95% Power:80% Ratio:1:1 </td> <td>50 </td> <td>15.6 </td> <td>-20 </td> <td>60 </td> </tr> <tr> <td>Pulmonary <a target='_blank' href='https://www.openaccessjournals.com/peer-reviewed-articles/hypertension-17.html'>hypertension</a> </td> <td>CI: 95% Power:80% Ratio:1:1 </td> <td>15.1 </td> <td>41.2 </td> <td>-20 </td> <td>94 </td> </tr> <tr> <td>Chronic <a target='_blank' href='https://www.openaccessjournals.com/peer-reviewed-articles/kidney-disease-220.html'>kidney disease</a> </td> <td>CI: 95% Power:80% Ratio:1:1 </td> <td>39.59 </td> <td>22.44 </td> <td>-25 </td> <td>230 </td> </tr> <tr> <td>Heart rate>100beats/min at presentation </td> <td>CI: 95% Power:80% Ratio:1:1 </td> <td>34.3 </td> <td>47.9 </td> <td>-25 </td> <td>412 </td> </tr> </tbody> </table> </div> <div class="alert alert-warning" role="alert"> <p> <strong>Abbreviations: </strong>CI:  Confidence interval </p> </div> <p><strong>Table 1:</strong> Sample size calculation for factors associated with in-hospital mortality of acute <a target='_blank' href='https://www.openaccessjournals.com/peer-reviewed-articles/heart-failure-3893.html'>heart failure</a> patients using Epi-Info software (version 7.2.4.0).</p> <p>Therefore, by adding 10% for contingency on the largest sample size, the calculated sample size was found to be 454 adult patients with AHF.</p> <p><strong><em>Sampling procedures and sampling techniques</em></strong></p> <p>The 907 adult patients were treated at HFCSH for AHF during the last five years.

However, our patients are younger than AHF patients are in global study and in developed countries, median age of 67 to 79 years [<a href="#30" title="30">30</a>,<a href="#31" title="31">31</a>]. The discrepancy might be due to high level of awareness on prevention of <a target='_blank' href='https://www.openaccessjournals.com/peer-reviewed-articles/cardiovascular-14501.html'>cardiovascular</a> disease, age cut-point differences of participants and life expectance of patients in developed countries. The overall in-hospital mortality was found to be 18.9% at a 95% confidence interval of 15.3% to 22.5%. Being female, having a smoking history, presence of generalized body swelling, <a target='_blank' href='https://www.openaccessjournals.com/peer-reviewed-articles/hypotension-1565.html'>hypotension</a> and tachycardia at admission were factors associated with in-hospital mortality.</p> <p>The magnitude of in-hospital mortality found in this study is 18.9% in the current study. A prospective study conducted at Tikur Anbessa Specialized Hospital, Ethiopia (17.2%) and a retrospective study conducted at Yaoundé Central Hospital, Cameroon (18.45%) reported similar magnitude of in-hospital mortality [<a href="#32" title="32">32</a>]. On the other hand, the finding of this study is higher than the studies reported from Gondar Comprehensive Specialized Hospital (10.6%), Middle East and North Africa (5.4%), and European and Mediterranean countries 5.3%. This could be due to advanced <a target='_blank' href='https://www.openaccessjournals.com/peer-reviewed-articles/health-2112.html'>health</a> care service in these study settings as they included patients from developed countries. However, it is lower than the study conducted in Addis Ababa, Ethiopia (24.4%). The discrepancy might be due to patient’s age difference, patient care process and setting differences.</p> <p>In this study, in-hospital mortality among females was 2.83 times more likely as compared to males. This might be attributable to a high proportion of female patients (62.1%) in this study. The finding is similar with the result reported from study conducted at St. Paul’s Hospital Millennium Medical College in Addis Ababa that showed the association of female sex with in-hospital mortality among <a target='_blank' href='https://www.openaccessjournals.com/peer-reviewed-articles/heart-failure-3893.html'>heart failure</a> patients.</p> <p>The odds of in-hospital mortality were more than double among those who had a smoking <a target='_blank' href='https://www.openaccessjournals.com/peer-reviewed-articles/history-8486.html'>history</a> than those who had no smoking history. Cigarette smoking is well-established <a target='_blank' href='https://www.openaccessjournals.com/peer-reviewed-articles/cardiovascular-14501.html'>cardiovascular</a> risk factor. It makes the heart work harder due to its blood pressure increasing effect and thus, negatively affect the treatment outcome of AHF [<a href="#33" title="33">33</a>,<a href="#34" title="34">34</a>]. Other studies also showed an association between smoking and in-hospital mortality among AHF patients [<a href="#35" title="35">35</a>].</p> <p>In-hospital mortality among patients who had generalized body swelling at admission was found to be 2.67 times more likely as compared to those who had no generalized body swelling at admission in the current study. Generalized body swelling is the result of the activation of a series of humoral and neurohumoral mechanisms that promote sodium and water reabsorption by the kidneys and expansion of the extracellular fluid. It occurs after signs of <a target='_blank' href='https://www.openaccessjournals.com/peer-reviewed-articles/dyspnea-18778.html'>dyspnea</a> and fatigue, which means it is not an early sign of heart failure, indicating that the acute <a target='_blank' href='https://www.openaccessjournals.com/peer-reviewed-articles/heart-failure-3893.html'>heart failure</a> patients with generalized body swelling is relatively at an advanced stage which negatively affects the outcome of the treatment [<a href="#36" title="36">36</a>].</p> <p>There were significant differences in clinical characteristics such as <a target='_blank' href='https://www.openaccessjournals.com/peer-reviewed-articles/hypotension-1565.html'>hypotension</a> between survivors and non-survivors among acute <a target='_blank' href='https://www.openaccessjournals.com/peer-reviewed-articles/heart-failure-3893.html'>heart failure</a> patients. In-hospital mortality among patients who had <a target='_blank' href='https://www.openaccessjournals.com/peer-reviewed-articles/hypotension-1565.html'>hypotension</a> was more than four times as compare to normotensive patients in present study. This may be due to the life threatening effect of shock. This finding is supported by other different studies [<a href="#37" title="37">37</a>,<a href="#38" title="38">38</a>].</p> <p>The odds of in-hospital mortality were more than four times higher among those who had tachycardia than those with normal heart rates in this study. The possible explanation is that as tachycardia is a compensatory mechanism in <a target='_blank' href='https://www.openaccessjournals.com/peer-reviewed-articles/heart-failure-3893.html'>heart failure</a> to meet the body’s oxygen and nutrient requirement, over time it causes a rapid decline in left ventricular function and worsens the acutely failed heart resulting in poor treatment outcome (death). This finding is almost similar with other studies that showed mortality rate is higher among patients with tachycardia. </p> <h3>Conclusion</h3> <p>In this study, in-hospital mortality is very high, which is almost one in six among patients admitted to HFCSH with AHF. Being female, having a smoking history, presences of generalized body swelling, <a target='_blank' href='https://www.openaccessjournals.com/peer-reviewed-articles/hypotension-1565.html'>hypotension</a> and tachycardia at admission were variables found to be significantly associated with in-hospital mortality among patients with AHF. Therefore, the current study outlined that there is a need for the reduction of in-hospital mortality among adult patients with acute <a target='_blank' href='https://www.openaccessjournals.com/peer-reviewed-articles/heart-failure-3893.html'>heart failure</a> in hospitals. Furthermore, a prospective research with strong design regarding in-hospital mortality and its associated factors among AHF is need to be conducted to investigate the problem in-depth and to establish causality.</p> <h3>Strength and limitations of the study</h3> <p>Although this study is among a few of its kind and it can serve as a stepping-stone for further investigation, it has some limitations. First, the study was based on a retrospective chart review. Thus, due to poor documentation, important variables like adherence and <a target='_blank' href='https://www.openaccessjournals.com/peer-reviewed-articles/adverse-drug-10707.html'>adverse drug</a> effect were missed. This might have influenced the results. Second, the data was collected from a single health facility and generalizability of the results is limited. Finally, since this study used cross-sectional study design, it cannot make a causal inference. Therefore, the authors recommend further follow-up study with stronger study design to address these limitations.</p> <h3>Availability of Data and Materials</h3> <p>All data generated or analyzed during this study are included in this manuscript. Data collection tool submitted with manuscript as Annexes (supplementary <a target='_blank' href='https://www.openaccessjournals.com/peer-reviewed-articles/information-7757.html'>information</a> files) and raw data can be accessible upon request from the authors.</p> <h3>Ethics Approval and Consent to Participate</h3> <p>Ethical clearance was obtained from Haramaya University, College of <a target='_blank' href='https://www.openaccessjournals.com/peer-reviewed-articles/health-2112.html'>Health</a> and Medical Sciences, Institutional Health Research Ethics Review Committee (IHRERC) with a reference number of IHRERC/131/2021 and all methods were performed in accordance with Declaration of Helsinki. Written information sheet and consent, which explained the study, was provided to the medical director of HFCSH (Additional file 2). Then, officials at different levels in the hospital were communicated through formal letters. Consent from all participants and/or their legal guardian(s) was not relevant for this study because data were collected from patient’s records, not directly from patients. The information collected in this study was kept confidential through not writing the name of patient on data collection tool. Only medical record number was used for identification. Data collectors informed and trained to preserve confidentiality of the patient <a target='_blank' href='https://www.openaccessjournals.com/peer-reviewed-articles/information-7757.html'>information</a> and the investigators used only for the study.</p> <h3>Authors Contributions</h3> <p>Chala Deriba is principal author responsible for designing the study, data collection and analysis and interpretation of the findings.
