RESUMO

The provision of effective urological management in low- and middle-income countries requires the delivery of appropriate and effective care adapted to the needs, capability and resources of the host country. However, a deeper cognisance of the culture, the religious practices and the logistics of healthcare in that environment determines the ability to effectively to 'twin', that is, to provide a long-term healthcare partnership. Patient beliefs can have profound effects on the understanding of the aetiology of illness, its relevance to their long-term health and the stigmatization of their family's social status. Consequently, individuals may have a greater willingness to seek help from practitioners of traditional medicine due to its availability as well as the lower costs of such medicine by comparison to those of medicine from high-income countries (HICs). This can influence the treatment of many urological conditions and lead to late-presenting states such as malignant ureteric obstruction. Social mores, such as cultural paternalism, can also influence many practices that are assumed by HICs to be part of normal healthcare provision, including the delivery of patient information and provision of informed consent to treatment. Doctor's status and dress have greater importance in many countries in sub-Saharan Africa (sSA) than in the UK and the modes of greeting and addressing colleagues and patients can affect the fluency and effectiveness of clinical interactions. A local cultural and religious knowledge is essential, therefore, to optimize the assimilation of external help. Logistics are perhaps the most important factor that needs to be grasped to provide a sustainable healthcare environment. Limitations in resource allocation are a major factor in planning effective urological treatment in many countries in sSA, whether this is the provision of trained personnel, basic infrastructure, a tenable workspace, equipment or drugs. This paper explores all of these factors, and looks at how their recognition assists urologists in providing a twinning process.

RESUMO

Regulation of medical care is something that has grown from humble roots in professional craft groups to huge establishment in well-resourced, high-income countries. Self-regulation was the preferred method of determining appropriate behaviour initially, but a lack of public trust in this, and the desire of patients to contribute to the establishment of the standard of care that they receive, has meant that most Anglophone countries have adopted some form of independent regulation. Regulators are responsible for the registration of doctor's qualifications, licensing them to practise, accrediting institutions to provide undergraduate and postgraduate education and certifying the attainment of accepted standards of achievement by some form of assessment process. Regulators also have powers to sanction individuals whose practice falls outside expected levels of competence. Both centralized and devolved models of regulation have evolved. Much of the accreditation for postgraduate education and training has been handed down to collegiate bodies, or non-governmental organizations, who can also certify completion of training. Evidence-based medicine and clinical practice guidelines have enforced an informal tier of regulation in high-income countries; guideline-derived practice is now widely regarded as an accepted standard of care. In low- and middle-income countries in sub-Saharan Africa the governmental and legislative structures and finance available to provide the regulation espoused in more privileged environments is rarely available. The workforce is structured in a completely different way and some care groups are totally unregulated. Medical councils in sub-Saharan Africa fulfil a registration and licensing function but surgical collegiate bodies provide the structure for postgraduate training. The East and West African Colleges of Surgeons have developed into robust organizations, who have verifiable, quality-assured, accreditation systems that have helped improve standards of care for the large populations for which their member surgeons are responsible. Formal regulation of continuing practice and sanctions are challenges that are, at present, largely unaddressed.

RESUMO

Urolithiasis is a global phenomenon. Cystolithiasis is common in parts of Africa due to low protein intake and dehydration from endemic diarrhoeal illnesses. Nephrolithiasis is less prevalent than in high-income countries, probably due to a variety of lifestyle issues, such as a more elemental diet, higher physical activity, and less obesity. Although renal stones are less common in low- and middle-income countries (LMICs), the social and economic impacts of nephrolithiasis are still considerable; many stones present late or with complications such as upper urinary tract obstruction or urosepsis. These may lead to the development of chronic kidney disease, or end-stage renal failure in a small proportion of cases, conditions for which there is very poor provision in most LMICs. Early treatment of nephrolithiasis by the least invasive method possible can, however, reduce the functional consequences of urinary stone disease. Although extracorporeal lithotripsy is uncommon, and endoscopic interventions for stone are not widespread in most of Africa, percutaneous nephrolithotomy and ureteroscopic renal surgery are viable techniques in those regional centres with infrastructure to support them. Longitudinal mentoring has been shown to be a key step in the adoption of these minimally invasive procedures by local surgeons, something that has been difficult during the coronavirus disease 2019 (COVID-19) pandemic due to travel restriction. Augmented reality (AR) technology is an alternative means of providing remote mentoring, something that has been trialled by Urolink, the MediTech Trust and other global non-governmental organisations during this period. Our preliminary experience suggests that this is a viable technique for promulgating skills in LMICs where appropriate connectivity exists to support remote communication. AR may also have long-term promise for decreasing the reliance upon short-term surgical visits to consolidate competence, thereby reducing the carbon footprint of global surgical education.

RESUMO

BACKGROUND: Intestinal volvulus is a common cause of mechanical intestinal obstruction (MIO) in Africa. Sigmoid volvulus has been well characterized in both high-income and low-income countries, but there is also a predilection for small bowel volvulus in sub-Saharan Africa. METHODS: An analysis was performed of the Kamuzu Central Hospital Acute Care Surgery Registry from 2013 to 2019 on patients presenting with intestinal volvulus. Bivariate analysis was performed for covariates based on the intestinal volvulus type. Multivariate Poisson regression models estimated the relative risk of volvulus and mortality. RESULTS: A total of 4352 patients were captured in the registry. Overall, 1037 patients (23.8%) were diagnosed with MIO. Intestinal volvulus accounted for 499 (48.1%) of patients with MIO. Sigmoid volvulus, midgut volvulus, ileosigmoid knotting, and cecal volvulus accounted for 57.7% (n = 288), 19.8% (n = 99), 20.8% (n = 104), and 1.6% (n = 8), respectively. Mean age was 46.8 years (SD 17.2) with a male preponderance (n = 429, 86.0%) and 14.8% (n = 74) mortality. Overall, the most common operations performed were large bowel (n = 326, 74.4%) and small bowel (n = 76, 16.7%) resections with 18.0% (n = 90) ostomy formation. Upon regression modeling, the relative risk for volvulus was 2.7 times higher in men than women after controlling for season and age. There was no statistically significant difference in the relative risk of mortality based on the type of volvulus. CONCLUSION: Volvulus is a significant cause of primary bowel obstruction in sub-Saharan Africa. Type of intestinal volvulus is not associated increased risk of mortality. Reasons for increases in the incidence of small bowel volvulus are still largely undetermined.

RESUMO

IMPORTANCE: In resource-limited settings, identification of successful and sustainable task-shifting interventions is important for improving care. OBJECTIVE: To determine whether the training of lay people to take vital signs as trauma clerks is an effective and sustainable method to increase availability of vital signs in the initial evaluation of trauma patients. DESIGN: We conducted a quasi-experimental study of patients presenting with traumatic injury pre- and post-intervention. SETTING: The study was conducted at Kamuzu Central Hospital, a tertiary care referral hospital, in Lilongwe, Malawi. PARTICIPANTS: All adult (age ≥ 18 years) trauma patients presenting to emergency department over a six-month period from January to June prior to intervention (2011), immediately post-intervention (2012), 1 year post-intervention (2013) and 2 years post-intervention (2014). INTERVENTION: Lay people were trained to take and record vital signs. MAIN OUTCOMES AND MEASURES: The number of patients with recorded vital signs pre- and post-intervention and sustainability of the intervention as determined by time-series analysis. RESULTS: Availability of vital signs on initial evaluation of trauma patients increased significantly post-intervention. The percentage of patients with at least one vital sign recorded increased from 23.5 to 92.1%, and the percentage of patients with all vital signs recorded increased from 4.1 to 91.4%. Availability of Glasgow Coma Scale also increased from 40.3 to 88.6%. Increased documentation of vital signs continued at 1 year and 2 years post-intervention. However, the percentage of documented vital signs did decrease slightly after the US-trained medical student and surgeon who trained the trauma clerks were no longer available in country, except for Glasgow Coma Scale. Patients who died during emergency department evaluation were significantly less likely to have vital signs recorded. CONCLUSIONS AND RELEVANCE: The training of lay people to collect vital signs and Glasgow Coma Scale is an effective and sustainable method of task shifting in a resource-limited setting.

RESUMO

BACKGROUND: Traumatic injury in the elderly is an emerging global problem with an associated increase in morbidity and mortality. This study sought to describe the epidemiology of elderly injury and outcomes in sub-Saharan Africa. METHODS: We conducted a retrospective analysis of adult patients (≥ 18 years) with traumatic injuries presenting to the Kamuzu Central Hospital (KCH) in Lilongwe, Malawi, over 5 years (2009-2013). Elderly patients were defined as adults aged ≥65 years and compared to adults aged 18-44 and 45-64 years. We used propensity score matching and logistic regression to compare the odds of mortality between age groups using the youngest age group as the reference. RESULTS: 42,816 Adult patients with traumatic injuries presented to KCH during the study period. 1253 patients (2.9 %) were aged ≥65 years with a male preponderance (77.4 %). Injuries occurred more often at home as age increased (25.3, 29.5, 41.1 %, p < 0.001) and falls were more common (14.1, 23.8, 36.3 %, p < 0.001) for elderly patients. Elderly age was associated with a higher proportion of hospital admissions (10.6, 21.3, 35.2 %, p < 0.001). Upon propensity score matching and logistic regression analysis, the odds ratio of mortality for patients aged ≥65 was 3.15 (95 % CI 1.45, 6.82, p = 0.0037) compared to the youngest age group (18-44 years). CONCLUSIONS: Elderly trauma in a resource-poor area in sub-Saharan Africa is associated with a significant increase in hospital admissions and mortality. Significant improvements in trauma systems, pre-hospital care, and hospital capacity for older, critically ill patients are imperative.

RESUMO

INTRODUCTION: There is a shortage of data on intimate partner and interpersonal violence in sub-Saharan Africa. We, therefore, sought to characterize patterns of sex-based risk of in-home interpersonal violence in Malawi. METHODS: We performed a retrospective analysis of the Kamuzu Central Hospital Trauma Registry data from 2009 to 2017 on adult patients presenting the emergency room following assault. Data variables collected include basic demographics, injury characteristics, and outcomes. We performed a bivariate analysis for covariates based on sex and Poisson regression analysis to estimate the risk of domestic violence and sex-based mortality. RESULTS: The in-home assault interpersonal violence was 37.1% (n = 10,854) of the total assault cohort and 37.4% (n = 4056) were female. Women were more likely to be assaulted at home (n = 4065, 69.6%)compared to men. The overall prevalence of in-home interpersonal violence over eight years was 9.09%, with the prevalence in men and women being 7.85 and 12.38%, respectively. Women injured following in-home interpersonal violence assaults were less severely injured. Women were more likely to be injured following slaps, punches, or kicks (n = 950, 41.2%) and men were more likely to be injured by an object, 41.0% with a blunt object (n = 1658) and 37.9% by a knife or another sharp object (n = 1532). For patients experiencing in-home interpersonal violence, overall mortality is 1.8% and 0.5% for men and women, respectively (p < 0.001). After controlling for covariates, the relative risk for In-home interpersonal violence was 2.25 (p < 0.001) times higher for women. Still, men had a 3.3 times risk of mortality following in-home interpersonal violence (p < 0.001). CONCLUSION: Interpersonal violence is a global problem. In Malawi, women are more likely to be victims of in-home interpersonal violence. However, men are more likely to die following in-home interpersonal violence. Prevalence of in-home interpersonal violence is likely an underestimation.

RESUMO

This article was migrated. The article was marked as recommended. Introduction: Malawi is among the world's least developed countries. There are 2.1 physicians per 100 000 people and a high trauma-related mortality and morbidity. The lack of healthcare resources requires essential high capacity trauma training at a low cost. Methods: A one-week trauma course was conducted at the Kamuzu Central Hospital in Lilongwe, Malawi. 15 students (13 interns and 2 chief nurses) attended the course. They were trained in initial trauma care, triage and basic practical procedures. Thereafter, evaluated through an identical multiple-choice exam, pre- (PRE) and post-course (POE), following a similar exam 6 months post-course (6MPOE). Prior to, and after the course a confidence-based questionnaire was completed. Results: The participants presented significantly higher test-scores after the course in both POE (26.2±3.2 vs. 21.8±3.1; p>0.001) and 6MPOE (25.7±2.4 vs. 21.8±3.1; p 0.003). We also identified the nurses to improve significantly after the course. The highest score of improvement was 27.3%. Higher confidence scores were noticed after the course. Conclusion: This study shows that any healthcare personnel in a low-income setting could benefit from a designed course in trauma management. Thus, we emphasize that healthcare staff undertake similar course to orient towards correct management and assessment of initial trauma patients.

RESUMO

BACKGROUND: Trauma is a major cause of paediatric mortality in sub-Saharan Africa. In absence of pre-hospital care, the injury mechanism and cause of death is difficult to characterise. Injury characteristics of pre-hospital deaths (PHD) versus in-hospital deaths (IHD) were compared. METHODS: Using our trauma surveillance database, a retrospective, descriptive analysis of children (<18 years) presenting to Kamuzu Central Hospital in Lilongwe, Malawi from 2008 to 2013 was performed. Patient and injury characteristics of pre-hospital and in-hospital deaths were compared with univariate and bivariate analysis. RESULTS: Of 30,462 paediatric trauma patients presenting between 2008 and 2013, 170 and 173 were PHD and IHD, respectively. In PHD and IHD patients mean age was 7.3±4.9 v 5.2±4.3 (p<0.001), respectively. IHD patients were more likely transported via ambulance than those PHD, 51.2% v 8.3% (p<0.001). The primary mechanisms of injury for PHD were road traffic injuries (RTI) (45.8%) and drowning (22.0%), with head injury (46.7%) being the predominant cause of death. Burns were the leading mechanism of injury (61.8%) and cause of death (61.9%) in IHD, with a mean total body surface area involvement of 24.7±16.0%. CONCLUSIONS: RTI remains Malawi's major driver of paediatric mortality. A majority of these deaths attributed to head injury occur prior to hospitalisation; therefore the mortality burden is underestimated if accounting for IHD alone. Death in burn patients is likely due to under-resuscitation or sepsis. Improving pre-hospital care and head injury and burn management can improve injury related paediatric mortality.

RESUMO

BACKGROUND: Head and neck squamous cell carcinoma (HNSCC) is common in sub-Saharan Africa, but the aetiologic contribution of human papillomavirus (HPV) is not well established. METHODS: We assessed HNSCC cases for HPV using p16 immunohistochemistry (IHC) in Malawi. Associations between p16 IHC and tumour site, behavioural risk factors, demographic characteristics, and HIV status were examined. RESULTS: From 2010 to 2014, 77 HNSCC cases were identified. Mean age was 52 years, 50 cases (65%) were male, and 48 (62%) were in the oropharynx (OP) or oral cavity (OC). HIV status was known for 35 patients (45%), with 5 (14%) HIV-infected. Substance use was known for 40 patients (52%), with 38% reporting any tobacco and 31% any alcohol. Forty-two cases (55%) had adequate tissue for p16 IHC, of which seven (17%) were positive, including 22% of OP/OC tumours. CONCLUSIONS: Despite high cervical cancer burden, HPV-associated HNSCC is not very common in Malawi.

RESUMO

BACKGROUND: Intentional injuries are the result of violence. This is an important public health issue, particularly in children, and is an unaddressed problem in sub-Saharan Africa. This study sought to describe the characteristics of intentional injury, particularly physical abuse, in children presenting to our tertiary trauma centre in Lilongwe, Malawi and how they compare to children with unintentional injuries. METHODS: A retrospective analysis of children (<18 years old) with traumatic injuries presenting to Kamuzu Central Hospital (KCH) in Lilongwe, Malawi from 2009 to 2013 was performed. Children with intentional and unintentional injuries were compared with bivariate analysis and multivariate logistic regression modelling. RESULTS: 67,672 patients with traumatic injuries presented to KCH of which 24,365 were children. 1976 (8.1%) patients presented with intentional injury. Intentional injury patients had a higher mean age (11.1 ± 5.0 vs. 7.1 ± 4.6, p<0.001), a greater male preponderance (72.5 vs. 63.6%, p<0.001), were more often injured at night (38.3 vs. 20.7%, p<0.001), and alcohol was more often involved (7.8 vs. 1.0%, p<0.001). Multivariate logistic regression modelling showed that increasing age, male gender, and nighttime or urban setting for injury were associated with increased odds of intentional injury. Soft tissue injuries were more common in intentional injury patients (80.5 vs. 45.4%, p<0.001) and fist punches were the most common weapon (25.6%). Most patients were discharged in both groups (89.2 vs 80.9%, p<0.001) and overall mortality was lower for intentional injury patients (0.9 vs. 1.2%, p=0.001). Head injury was the most common cause of death (43.8 vs. 32.2%, p<0.001) in both groups. CONCLUSIONS: Sub-Saharan African tertiary hospitals are uniquely positioned to play a pivotal role in the identification, clinical management, and alleviation of intentional injuries to children by facilitating access to social services and through prevention efforts.

RESUMO

BACKGROUND: Improved access to surgical care could prevent a significant burden of disease and disability-adjusted life years, and workforce shortages are the biggest obstacle to surgical care. To address this shortage, a 5-year surgical residency program was established at Kamuzu Central Hospital (KCH) in July 2009. As the residency enters its fourth year, we hypothesized that the initiation of a general surgical residency program would result in an increase in the overall case volume and complexity at KCH. METHODS: We conducted a retrospective analysis of operated cases at KCH during the 3 years before and the third year after the implementation of the KCH surgical residency program, from July 2006 to July 2009 and the calendar year 2012, respectively. RESULTS: During the 3 years before the initiation of the surgical residency, an average of 2317 operations were performed per year, whereas in 2012, 2773 operations were performed, representing a 20% increase. Before residency, an average of 1191 major operations per year were performed, and in 2012, 1501 major operations were performed, representing a 26% increase. CONCLUSION: Our study demonstrates that operative case volume and complexity increase following the initiation of a surgical residency program in a sub-Saharan tertiary hospital. We believe that by building on established partnerships and emphasizing education, research, and clinical care, we can start to tackle the issues of surgical access and care.

RESUMO

IMPORTANCE: Changes in pulmonary dynamics following laparotomy are well documented. Deep breathing exercises, with or without incentive spirometry, may help counteract postoperative decreased vital capacity; however, the evidence for the role of incentive spirometry in the prevention of postoperative atelectasis is inconclusive. Furthermore, data are scarce regarding the prevention of postoperative atelectasis in sub-Saharan Africa. OBJECTIVE: To determine the effect of the use of incentive spirometry on pulmonary function following exploratory laparotomy as measured by forced vital capacity (FVC). DESIGN, SETTING, AND PARTICIPANTS: This was a single-center, randomized clinical trial performed at Kamuzu Central Hospital, Lilongwe, Malawi. Study participants were adult patients who underwent exploratory laparotomy and were randomized into the intervention or control groups (standard of care) from February 1 to November 30, 2013. All patients received routine postoperative care, including instructions for deep breathing and early ambulation. We used bivariate analysis to compare outcomes between the intervention and control groups. INTERVENTION: Adult patients who underwent exploratory laparotomy participated in postoperative deep breathing exercises. Patients in the intervention group received incentive spirometers. MAIN OUTCOMES AND MEASURES: We assessed pulmonary function using a peak flow meter to measure FVC in both groups of patients. Secondary outcomes, such as hospital length of stay and mortality, were obtained from the medical records. RESULTS: A total of 150 patients were randomized (75 in each arm). The median age in the intervention and control groups was 35 years (interquartile range, 28-53 years) and 33 years (interquartile range, 23-46 years), respectively. Men predominated in both groups, and most patients underwent emergency procedures (78.7% in the intervention group and 84.0% in the control group). Mean initial FVC did not differ significantly between the intervention and control groups (0.92 and 0.90 L, respectively; P=.82 [95% CI, 0.52-2.29]). Although patients in the intervention group tended to have higher final FVC measurements, the change between the first and last measured FVC was not statistically significant (0.29 and 0.25 L, respectively; P=.68 [95% CI, 0.65-1.95]). Likewise, hospital length of stay did not differ significantly between groups. Overall postoperative mortality was 6.0%, with a higher mortality rate in the control group compared with the intervention group (10.7% and 1.3%, respectively; P=.02 [95% CI, 0.01-0.92]). CONCLUSIONS AND RELEVANCE: Education and provision of incentive spirometry for unmonitored patient use does not result in statistically significant improvement in pulmonary dynamics following laparotomy. We would not recommend the addition of incentive spirometry to the current standard of care in this resource-constrained environment. TRIAL REGISTRATION: clinicaltrials.gov Identifier: NCT01789177.

RESUMO

INTRODUCTION: Non-communicable diseases including surgical conditions are gaining attention in developing countries. Despite this there are few metrics for surgical capacity. We hypothesized that (a) the ratio of emergent to total hernia repairs (E/TH) would correlate with per capita health care expenditures for any given country, and (b) the E/TH is easy to obtain in resource-poor settings. METHODS: We performed a systematic review to identify the E/TH for as many countries as possible (Prospero registry CRD42013004645). We screened 1285 English language publications since 1990; 23 met inclusion criteria. Primary data was also collected from Kamuzu Central Hospital (KCH) in Lilongwe, Malawi. A total of 13 countries were represented. Regression analysis was used to determine the correlation between per capita health care spending and the E/TH. RESULTS: There is a strong correlation between the log values of the ratio emergent to total groin hernias and the per capita health care spending that is robust across country income levels (R(2) = 0.823). Primary data from KCH was easily obtained and demonstrated a similar correlation. CONCLUSIONS: The ratio of emergent to total groin hernias is a potential measure of surgical capacity using data that is easily attainable. Further studies should validate this metric against other accepted health care capacity indicators. Systematic review registered with Prospero (CRD42013004645).

RESUMO

BACKGROUND: Injuries are the ninth leading cause of death in the world and disproportionately affect low- and middle-income countries. Head injury is the leading cause of trauma death. This study examines the epidemiology and outcomes of traumatic head injury presenting to a tertiary hospital in Malawi, in order to determine effective triage in a resource limited setting. METHODS: The study was conducted at Kamuzu Central Hospital (KCH) in Lilongwe Malawi during a three-month period. Vital signs and Glasgow Coma Score (GCS) were prospectively collected for all patients that presented to the casualty department secondary to head injury. All head injury admissions were followed until death or discharge. RESULTS: During the three-month study period, 4411 patients presented to KCH secondary to trauma and 841 (19%) had a head injury. A multivariate logistic regression model revealed that GCS and heart rate changes correlated strongly with mortality. There is a four-fold increase in the odds of mortality in moderate versus mild head injury based on GCS. CONCLUSION: In a resource limited setting, basic trauma tools such as GCS and heart rate can effectively triage head injury patients, who comprise the most critically ill trauma patients. Improvements in head injury outcome require multifaceted efforts including the development of a trauma system to improve pre-hospital care.

RESUMO

BACKGROUND: Worldwide, new cancer cases will nearly double in the next 20 years while disproportionately affecting low and middle income countries (LMICs). Cancer outcomes in LMICs also remain bleaker than other regions of the world. Despite this, little is known about cancer epidemiology and surgical treatment in LMICs. To address this we sought to describe the characteristics of cancer patients presenting to the Surgery Department at Kamuzu Central Hospital in Lilongwe, Malawi. METHODS: We conducted a retrospective review of adult (18 years or older) surgical oncology services at Kamuzu Central Hospital in Lilongwe, Malawi from 2007 - 2010. Data obtained from the operating theatre logs included patient demographics, indication for operative procedure, procedure performed, and operative procedures (curative, palliative, or staging). RESULTS: Of all the general surgery procedures performed during this time period (7,076 in total), 16% (406 cases) involved cancer therapy. The mean age of male and female patients in this study population was 52 years and 47 years, respectively. Breast cancer, colorectal cancer, gastric cancer, and melanoma were the most common cancers among women, whereas prostate, colorectal, pancreatic, and, gastric were the most common cancers in men. Although more than 50% of breast cancer operations were performed with curative intent, most procedures were palliative including prostate cancer (98%), colorectal cancer (69%), gastric cancer (71%), and pancreatic cancer (94%). Patients with colorectal, gastric, esophageal, pancreatic, and breast cancer presented at surprisingly young ages. CONCLUSION: The paucity of procedures with curative intent and young age at presentation reveals that many Malawians miss opportunities for cure and many potential years of life are lost. Though KCH now has pathology services, a cancer registry and a surgical training program, the focus of surgical care remains palliative. Further research should address other methods of increasing early cancer detection and treatment in such populations.

RESUMO

INTRODUCTION: The World Health Organization (WHO) recommends HIV Counseling and Testing (HCT) in a range of clinical settings. We describe the characteristics of patients diagnosed with HIV on the medical and surgical wards at a tertiary care hospital in Malawi. METHODS: Under the universal opt-out HCT protocol we characterized the number of new HIV/AIDS infections and associated clinical features among hospitalized surgical and medical patients diagnosed during the course of admission. RESULTS: All 2985 and 3959 medical and surgical patients, respectively, admitted between April 2012 and January 2013 were screened for HCT. 62% and 89% of medical and surgical patients, respectively, had an unknown status on admission and qualified for testing. Of the patients with an unknown status, a new HIV diagnosis was made in 20% and 7% of medical and surgical patients, respectively. Of the newly diagnosed patients with a CD4 count recorded, 91% and 67% of medical and surgical patients, respectively, had a count less than 350, qualifying for ART by Malawi ART guidelines. Newly HIV-diagnosed medical and surgical patients had an inpatient mortality of 20% and 2%, respectively. DISCUSSION: While newly diagnosed HIV-positive medical patients had high inpatient mortality and higher rates of WHO stage 3 or 4 conditions, surgical patients presented with less advanced HIV, though still meeting ART initiation guidelines. The medical inpatient wards are an obvious choice for implementing voluntary counseling and testing (VCT), but surgical patients present with less advanced disease and starting treatment in this group could result in more years of life gained.
