Implementation of a clinical breast exam and referral program in a rural district of Pakistan.

BACKGROUND: The role of clinical breast examination (CBE) for early detection of breast cancer is extremely important in lower-middle-income countries (LMICs) where access to breast imaging is limited. Our study aimed to describe the outcomes of a community outreach breast education, home CBE and referral program for early recognition of breast abnormalities and improvement of breast cancer awareness in a rural district of Pakistan. METHODS: Eight health care workers (HCW) and a gynecologist were educated on basic breast cancer knowledge and trained to create breast cancer awareness and conduct CBE in the community. They were then deployed in the Dadu district of Pakistan where they carried out home visits to perform CBE in the community. Breast cancer awareness was assessed in the community using a standardized questionnaire and standard educational intervention was performed. Clinically detectable breast lesions were identified during home CBE and women were referred to the study gynecologist to confirm the presence of clinical abnormalities. Those confirmed to have clinical abnormalities were referred for imaging. Follow-up home visits were carried out to assess reasons for non-compliance in patients who did not follow-through with the gynecologist appointment or prescribed imaging and re-enforce the need for follow-up. RESULTS: Basic breast cancer knowledge of HCWs and study gynecologist improved post-intervention. HCWs conducted home CBE in 8757 women. Of these, 149 were warranted a CBE by a physician (to avoid missing an abnormality), while 20 were found to have a definitive lump by HCWs, all were referred to the study gynecologist (CBE checkpoint). Only 50% (10/20) of those with a suspected lump complied with the referral to the gynecologist, where 90% concordance was found between their CBEs. Follow-up home visits were conducted in 119/169 non-compliant patients. Major reasons for non-compliance were a lack of understanding of the risks and financial constraints. A significant improvement was observed in the community's breast cancer knowledge at the follow-up visits using the standardized post-test. CONCLUSIONS: Basic and focused education of HCWs can increase their knowledge and dispel myths. Hand-on structured training can enable HCWs to perform CBE. Community awareness is essential for patient compliance and for early-detection, diagnosis, and treatment.

Reducing post-operative length of stay, is it worth the effort?

BACKGROUND: Studies show that reducing the length of hospital stay (LOS) for surgical patients leads to cost savings. We hypothesize that LOS has a nonlinear relationship to cost of care and reduction may not have a meaningful impact on it. We have attempted to define the relationship of LOS to cost of care. We utilized the itemized bill, generated in real time, for hospital services. MATERIALS: Adult patients admitted under General, Neuro, and Orthopedic surgery over a 3-month period, with an LOS between 4 and 14 days, were the study population. Itemized bill details were analyzed. Charges in Pakistani rupees were converted to US dollar. Ethical exemption for study was obtained. RESULTS: Of the 853 patients, 38% were admitted to General Surgery, 27% to Neurosurgery, and 35% to Orthopedics. A total of 64% of the patients had an LOS between 4 and 6 days; 36% had an LOS between 7 and 14 days. Operated and conservatively managed constituted 82% and 18%, respectively. Mean total charge for operated patients was higher $3387 versus $1347 for non-operated ones. LOS was seen to have a nonlinear relationship to in-hospital cost of care. The bulk of cost was centered on the day of surgery. This was consistent across all services. The last day of stay contributed 2.4%-3.2% of total charge. CONCLUSIONS: For surgical patients, the cost implications rapidly taper in the postoperative period. The contribution of the last day of stay cost to total cost is small. For meaningful cost containment, focus needs to be on the immediate perioperative period.

Medication Adherence in Patients With Uncontrolled Hypertension & Hypertensive Crisis Presenting to a Hospital Setting in Karachi, Pakistan.

BACKGROUND: Hypertension is an established risk factor for cardiovascular disease. Non-adherence to antihypertensive medications contributes to poorly controlled hypertension while also increasing the risk of hypertensive crisis. The aim of our study was thus to estimate the frequency of adherence to antihypertensive medications in our population and also see if an association exists between adherence and the development of a hypertensive crisis. METHODS: This cross-sectional study was undertaken on patients admitted to Aga Khan University Hospital, Karachi, Pakistan, between July 2020 and March 2022. All patients with uncontrolled hypertension with systolic blood pressure >140 and diastolic blood pressure >90 who were admitted through the emergency department were included. A systolic blood pressure over 180mmHg or diastolic blood pressure over 120mmHg, with or without end-organ damage was used to define a hypertensive crisis. Adherence to medications was assessed using the 4-item Morisky Green Levine (MGL) scale. Each item was scored as 1 and then added together to get a final score out of 4 with a score of ≥3 signifying adherence while a cumulative score of 0, 1, or 2 was classified as non-adherence. RESULTS: We found that 64% of the cohort were adherent to their medications while 93 (36%) were non-adherent. The most common comorbid condition was found to be diabetes mellitus (54.8%). Around 146 (64.6%) patients were on a single anti-hypertensive agent. Depression as calculated according to the hospital anxiety and depression scale (HADS) was seen in 133 (51.2%) of our cohort while 147 (56.5%) had anxiety. Similar rates of adherence were seen amongst males (49.1%) and females (50.9%). The highest level of adherence was seen in the 61 to 75 years age group (34.9%) and in those with university-level education (30.6%). We also found a statistically significant association between adherence to antihypertensive medications with anxiety (p-value=0.048). Moreover, in the hypertensive crisis group, 40.7% of the patients were adherent to their antihypertensive medications while 54.8% were found to be non-adherent, with the p-value reaching statistical significance (p-value=0.028). CONCLUSION: We found a higher rate of adherence (64%) in this inpatient hypertensive population as compared to previous studies in our population. We also found that non-adherence is a risk factor for the development of a hypertensive crisis. Therefore, at clinic visits, physicians should assess their patient's adherence to antihypertensive medications to prevent the development of a hypertensive crisis.

Association of Depression and Anxiety With Hypertensive Crisis: A Cross-Sectional Study From a Hospital Setting in Karachi, Pakistan.

Introduction Hypertension, a leading risk factor for cardiovascular death, has been closely linked with depression and anxiety. The aim of this study was to examine the association of depression or anxiety with hypertensive crisis in patients and also see if the association is affected by age group or gender. This was carried out in a hospital setting. Methods This cross-sectional study was conducted between July 2019 and March 2022 on 290 patients admitted to the Aga Khan University Hospital (AKUH), Karachi, Pakistan. All adult patients more than 18 years of age admitted with uncontrolled hypertension with a systolic blood pressure of >140 and a diastolic blood pressure of >90 admitted through emergency were included. A hypertensive crisis was defined as a systolic blood pressure greater than 180 mm Hg or a diastolic blood pressure greater than or equal to 120 mm Hg, with or without accompanying end organ damage. Symptoms of depression and anxiety were evaluated using the Hospital Anxiety and Depression Scale (HADS), with a cut-off score ≥8. Results Of the patients identified with uncontrolled hypertension, a total of 140 (48.3%) of the patients presented with a hypertensive crisis, while 150 (51.3%) did not have a hypertensive crisis at presentation. In the hypertensive crisis group, 60 (49.3%) had HADS scores consistent with depression, while 83 (59.3%) had HADS scores consistent with anxiety. In patients with hypertensive crisis, HADS depression and anxiety were most prevalent in the 61-75 age group (39.7%). In the comparison of gender, it was found that males and females with hypertensive crisis had an almost equal prevalence of anxiety (49.4% in males versus 50.6% in females). A slightly higher prevalence of depression was seen in females with hypertensive crises when compared to males. Conclusion We found no association between depression or anxiety with hypertensive crisis, and the association is not affected by age group or gender. However, do note that half of the patients with hypertensive crises had depression or anxiety. Future large multicentered studies are required to study the link in greater detail.

Case Study of Pediatric Cerebral Sinus Venous Thrombosis Center of a Low Middle-Income Country.

Pediatric cerebral venous sinus thrombosis (CVST) is rare but a potentially fatal disease requiring its understanding in local setting. In this study, we observed the clinical course, management, and outcome of pediatric patients with sinus thrombosis in a tertiary care center at Pakistan. Patients between age 0 to 18 years of both genders diagnosed with sinus thrombosis during 2011 to 2020 were included. Data was collected through in-house computerized system and SPSS version 19 was used for analysis. Of 143492 pediatric admissions, 32 (21 males and 11 females) patients with a median (IQR) age of 4.5 years (0-16) had CVST. This is equivalent to 18.5 CVST events per million pediatric admissions. Adolescents were mostly affected, and the overall mortality was 7%. Primary underlying disorders were infections (59%), hematological neoplasms (12.5%), thrombotic thrombocytopenic purpura (3%) and antiphospholipid syndrome (3%). Activated protein C resistance (44%) was the most common inherited thrombophilia. Twenty-one (66%) patients were anemic with a mean (±SD) hemoglobin of 9.0 g/dL (±2.3). Regression analysis showed a positive association of anemia with multiple sinus involvement (P-value 0.009) but not with duration of symptoms (P-value 0.344), hospital stay (P-value 0.466), age (P-value 0.863) or gender (P-value 0.542) of the patients. SARS-COV2 was negative in patients during 2020. Adolescents were primarily affected by sinus thrombosis and infections was the predominant risk factor for all age groups, with a low all-cause mortality. A high index of clinical suspicion is required for prompt diagnosis and intervention.

Intraoperative hypothermia in patients undergoing Total knee arthroplasty: a cross-sectional study from a developing country.

BACKGROUND: Intraoperative hypothermia is associated with various risk factors, morbidity, and mortality in patients undergoing total knee arthroplasty (TKA), increasing the emotional and financial burden on patients. This study aimed to identify risk factors of intraoperative hypothermia in patients undergoing TKA. MATERIALS AND METHODS: All adult patients (⩾18 years) who underwent TKA from January 2016 to December 2017 at a tertiary-care hospital in Pakistan were included in this retrospective, cross-sectional study. Temperature < 36 °C was defined as hypothermia. RESULTS: The study included 286 patients (77.6% female) with a mean age of 61.4 ± 10.4 years. The overall proportion of intraoperative hypothermia was 26.6%. Of the total patients, 66.1% underwent bilateral TKA whereas 33.9% underwent unilateral TKA. 73.8% of the patients were ASA Level 2. Only 13.3% of patients had postoperative hypothermia. CONCLUSION: Intraoperative hypothermia was significantly associated with age, bilateral procedure, ASA level and postoperative hypothermia in patients undergoing TKA. The surgeon and the operative team should be aware of the risk factors and the adverse outcomes associated with intraoperative hypothermia, especially in resource constrained settings to plan preventive strategies. TRIAL REGISTRATION: This study was retrospectively registered on ClinicalTrials.gov on 3rd October 2020. The registration ID is NCT04575246 .

Risk Assessment and Outcome of Venous Thromboembolism in Pediatric Population in an Academic Care Center of a Low-Middle Income Country.

Venous thromboembolism (VTE) is a recognized complication of hospital stay in young patients in many developed countries, but such an information is largely unavailable from a low middle-income country (LMIC). This study aimed at identifying the frequency, risk factors, treatment options and outcome of deep venous thrombosis/pulmonary embolism (DVT/PE) in pediatric population in a tertiary care center from a LMIC. International classification of disease, ninth revision (ICD-9) was used to identify VTE in patients aged 0-18 years during January 2011 to September 2019. In-house computerized system was used to collect data for demographics, clinical and laboratory details. SPSS version 19 was used to analyzed data. The study was approved by Institutional ethical review committee (3872-Pat-ERC-15). During the study period, 134617 pediatric patients were hospitalized, DVT/PE was observed in 77 unique patients (47 males and 30 females) with a median (IQR) age of 14 (5-16) years equivalent to 5.9 VTE events /10,000 hospital admissions. Malignancy, community acquired infections and autoimmune diseases were the predominant risk factors (75%) in adolescent age-group while surgery for congenital heart anomalies was the primary reason (71%) in infants. Overall, lower extremity thrombosis was the most frequent (51%) followed by pulmonary embolism (25%). and upper extremity thrombosis (24%). Enoxaparin and unfractionated heparin were mainly used to treat VTE and all-cause mortality was 13% in the cohort studied. We observed substantial VTE events in pediatric patients during their hospital stay in a tertiary care center of a low-middle income country.
