Evaluating potential unexpected adverse events and mortality after oral analgesics administration in fracture care-a cohort study.

INTRODUCTION: Analgesic selection per individual's tolerance is essential to avoid risks. The study evaluated current oral analgesic prescription practice, analgesic adverse effects-related factors, unexpected events, and mortality post-fracture surgery. RESEARCH DESIGN AND METHODS: The present prospective cohort study from June 2022 to July 2023 enrolled a total of 198 proximal femoral, ankle, and hindfoot trauma fracture patients. Stratification was done for oral analgesics prescribed at hospital discharge and 1 week with their accompanying toxicity assessed for 2 weeks. Analyzed Kaplan-Meier curve and the absolute risk for possible analgesics-related deaths. RESULTS: Following oral analgesic administration, 122 (62%) patients experienced adverse events. In seven expiries, five were possibly due to acetaminophen added tramadol combined with any of pregabalin, diclofenac, etoricoxib, or gabapentin (absolute risk 2.5%, 97.5% proportion 2 weeks survival). Three (2% of 122) patients taking acetaminophen added tramadol or diclofenac experienced unexpected serious adverse events. Elderly diabetic and hypertensive hip fracture patients expired or experienced unexpected events. CONCLUSION: Data suggest that oral acetaminophen added tramadol combined with any of pregabalin, diclofenac, etoricoxib, or gabapentin might increase the death risk or unexpected serious adverse events in elderly diabetic and hypertensives suffering from intertrochanteric/femoral neck fracture. Safe analgesic selection is necessitated for at-risk patients.

Microbiology of surgical site infection in closed upper limb fractures: Data from a prospective trauma registry.

The current study aims to determine the rate of surgical site infection, causal microorganism, and antibiotic sensitivity pattern in operated upper limb closed fractures at the Aga Khan University Hospital, Karachi. Cases presenting between June 2015 to October 2019, were selected from a single-centre, longitudinal, prospective orthopaedic trauma registry. Infection rate, causal microorganism, and antibiotic sensitivity pattern were determined up to six months after surgery. From among a total of 376 closed fractures, 12 encountered surgical site infection with some having late onset, giving an infection rate of 3% which is 1% higher than the international benchmark. Microorganism culture was performed on 5 (42%) patients out of which 2 (40%) were positive. Frequently used prophylactic antibiotics were first generation Cephalosporin and Co-amoxiclav in 9 (75%) patients, but all other patients required other antibiotic categories. Five patients required implant removal with antibiotic coverage. K-wire insertion required prolonged antibiotic treatment. Most of the cultures were negative in spite of the presence of infection.

Is Hypothyroidism Associated With Outcomes in Fracture Patients? Data From a Trauma Registry.

BACKGROUND: Previous research reports suggesting the susceptibility of patients with hypothyroidism to fragility fractures. The current study aimed to compare injury factors, patient factors, and outcomes of fractures in patients with and without hypothyroidism. METHODS: Study data were extracted from an ongoing single-center prospective orthopaedic trauma registry at a tertiary care hospital. Patients recruited between June 2015 and March 2020 were selected. Patients were grouped into those with and without hypothyroidism, and data on injury factors, management, clinical, and functional outcomes up to 6 mo were compared. Relation of fracture with TSH levels and age was analyzed, and prescription of bone-strengthening supplements was recorded in the hypothyroid group. RESULTS: Among 1347 patients recruited in the trauma registry, 35 patients had hypothyroidism of which 77% were females compared to 30% of euthyroid subjects (P = 0.0001). The most commonly involved anatomic sites identified were the proximal femur and proximal humerus. Low-energy trauma more likely occurred in hypothyroid (71%) compared to 32% of euthyroid subjects (P < 0.001). Osteoporosis was identified in 90% of hypothyroid subjects who underwent a DEXA scan. The clinical and functional outcomes of patients seem to be similar in both groups, possibly due to adequate control of hypothyroidism or the effect of bone-strengthening supplements given to hypothyroid patients. Serum TSH level and age were not related to low-energy trauma in hypothyroid patients. CONCLUSIONS: The current study identified that patients with hypothyroidism presenting with fractures are more likely females with low-energy trauma, involving the proximal femoral, and humeral fractures. Thyroid status was not associated with post-management outcomes.

Functional outcomes in proximal humerus fractures: A prospective registry-based analysis.

The present study evaluated and compared functional outcomes of proximal humerus fractures of different categories and their management with different procedures. Data of this prospective cohort was obtained from the orthopaedic trauma registry at a tertiary care hospital for the period from June 2015 to October 2019. Sixty-eight adult patients with proximal humerus fracture were identified out of which 57 (84%) had been operated. Functional outcomes were assessed up to 12-month follow-ups and were compared with different treatment groups, fracture category, and between isolated versus proximal humerus with additional upper limb fractures. At 3-month follow-up, there was significantly better outcomes in Proximal Humeral Internal Locking System (PHILOS) treatment group as compared to PHILOS with bone graft/BMP (p=0.041). PHILOS combined with bone graft/BMP was associated with delayed recovery compared to other management methods. There was non-significant difference in functional outcomes between isolated versus proximal humerus fractures associated with other upper limb fractures, among different fracture categories and between genders.

Clinical characteristics and outcomes of COVID-19: Experience at a major tertiary care center in Pakistan.

INTRODUCTION: Limited data exist on clinical characteristics and outcomes of hospitalized COVID-19 patients in low-middle income countries. We aimed to describe the clinical spectrum and outcomes of hospitalized COVID-19 patients at a tertiary-care center in Karachi, Pakistan. METHODOLOGY: We conducted an observational study of adult COVID-19 patients hospitalized between February-June 2020. Patients with a discharge diagnosis of COVID-19 and PCR positivity were included. We created logistic regression models to understand association of clinical characteristics with illness severity and in-hospital mortality. RESULTS: The study population comprised 445 patients [67% males, median age 53 (IQR 40-64) years]. Majority of patients (N = 268; 60%) had ≥ 1 co-morbid [37.5% hypertension, 36.4% diabetes]. In-hospital mortality was 13%. Age ≥ 60 (aOR] =1.92; 95 %CI = 1.23-3.03), shortness of breath (aOR=4.43; 95% CI=2.73-7.22), CRP ≥150mg/L (aOR:1.77; 95% CI=1.09-2.85), LDH ≥ 500 I.U/L (aOR:1.98; 95% CI=1.25-3.16), Neutrophil-to-Lymphocyte ratio (NLR) ≥5 (aOR:2.80; 95%CI = 1.77-4.42) and increase in serum creatinine (aOR:1.32; 95%CI=1.07-1.61) were independently associated with disease severity. Septic shock (aOR: 13.27; 95% CI=3.78-46.65), age ≥ 60 (aOR: 3.26; 95% CI=1.07-9.89), Ferritin ≥ 1500ng/ml (aOR: 3.78; 95% CI=1.21-11.8), NLR ≥ 5 (aOR: 4.04; 95% CI=1.14-14.35) and acute kidney injury (aOR: 5.52; 95% CI=1.78-17.06) were independent predictors of in-hospital mortality. CONCLUSIONS: We found multiple predictors to be independently associated with in-hospital mortality, except diabetes and gender. Compared to reports from other countries, the in-hospital mortality among COVID-19 patients was lower, despite a high burden of co-morbidities. Further research is required to explore reasons behind this dichotomy.

Patient outcomes association with patient factors and care provided: trauma registry derived cohort study.

OBJECTIVE: To determine the association of delay in treatment with injury-specific patient outcomes. METHODS: This was a single-center, longitudinal cohort study on orthopaedic trauma registry. Data on patients enrolled between June 2015 and June 2018 were analyzed. Data was collected from admitted consenting patients' medical records. Definitive surgical care provided after 24 hours was considered as 'delayed surgical treatment'. Outcomes of patients were serially assessed on follow-up visits up to 12 months using injury-specific scoring system. RESULTS: A total of 789 patients, were enrolled with 856 upper or lower extremity injuries altogether; in 67 cases both extremities were involved. Surgery was done in 90% while 10% were managed conservatively. A delay in the surgical procedure was experienced by 185(23%) patients. Mortality was 3.28% (6 of 185) in the delayed treatment group and 1% (6 of 603 patients) in the early treatment group (p=0.046). In proximal femur there was a nonsignificant trend towards better outcomes in the early treatment group at 3 and 12 months (p=0.06), while in Tibial shaft fractures, there was a non-significant trend towards better outcomes in the delayed treatment group at 3 and 6-months (p=0.09). There was no association between treatment delay for distal radius and proximal humerus fractures and their outcomes. CONCLUSIONS: Our trauma registry model provides outcomes data enabling identification of patient subsets who did not achieve good outcome, and suggests possible role of delay in surgical treatment beyond 24 hours in the outcomes..

Functional and clinical outcomes of open versus closed radius and ulna shaft fractures in adults: A prospective cohort study.

OBJECTIVE: To compare functional and clinical outcomes of open versus closed radius ulna shaft fractures in adults treated by internal fixation. METHODS: A prospective cohort study was conducted on patients presenting with traumatic radius and ulna shaft fractures to Aga Khan University and undergoing internal fixation between July 2015 to June 2019. Data was extracted from an ongoing orthopaedic trauma registry. Functional and clinical outcomes were assessed by Price et al. criteria at 6 weeks, 3, 6 and 12 months follow-up. Outcome scores of open versus closed fractures were compared. RESULTS: Twenty-nine adult patients with isolated radius and ulna shaft fracture were identified. Cause of injury was road traffic accident in 18 (62%) and fall in 11 (38%) patients. Seventeen (59%) were closed and 12 (41%) were open fractures. At 6week follow-up, better outcomes were observed in closed fracture group (p=0.01) with near-full range of motion and activity in 10(83%) patients as compared to 3(27%) in the open fracture group. No significant difference in outcomes was observed at 3 months and thereafter. CONCLUSIONS: Earlier recovery of function at 6 weeks was observed in majority of patients in the closed fracture group. Our data shows that good-excellent functional and clinical results are achievable by internal fixation in both open as well as closed fractures of the shaft of radius and ulna in adults.

Comparison of intraarticular distal humerus fracture outcomes treated with or without olecranon osteotomy - A case series.

A case series was extracted from the trauma registry at Aga Khan University Hospital from the period June 2015 to June 2019. Included were 16 adult patients who presented with intra-articular distal humerus fracture type C2. The functional, clinical and radiological outcomes of fractures treated with or without olecranon osteotomy up to 12 months follow-up were compared. Outcomes were assessed at 6 weeks, 3, 6 and 12 months re-visits. Among the 16 studied patients, 9 (56%) were males and 7 (44%) were females. In the group without osteotomy, there was a good functional and clinical outcome with a mean Quick Disability of the Arm, Shoulder and Hand score of 32±30 at 3 months post-procedure. Bone healing was noticed at 6 months after surgery. In the osteotomy group, 50%-70% bone union was seen at 3 months post-surgery while fair functional and clinical outcome was achieved at 6 months after surgery.

Injury specific trauma registry: Outcomes of a prospective cohort with proximal femur fractures.

BACKGROUND: The elderly population is prone to hip fractures, and treating such patients to achieve good outcomes can be challenging. Collection of outcomes data can support clinicians to modify their treatment protocols and improve outcomes over time. The aim of this study is to compare different surgical procedures in patients with neck of femur and intertrochanteric fractures in terms of clinical, functional and radiological outcomes using injury-specific outcome scores. METHODS: The study data was derived from the existing single-center, prospective orthopaedic trauma registry initiated from July 2015. Functional, clinical and radiological outcomes were assessed using Modified Harris Hip Score and The Radiographic Union Score for Hip. Mean radiological outcome scores was compared by Mann-Whitney U test and deaths by Chi-square and Odds ratio. RESULTS: Of the total 138 patients, 53 (38%) were neck of femur and 85 (62%) Intertrochanteric fractures with fall as leading cause of injury. At 12 months follow-up, modified Harris Hip Score showed 67% excellent-good results in both dynamic hip screw (N = 6) and total hip replacement (N = 3) followed by 50% in intramedullary nail (N = 2). Hemiarthroplasty has fair-poor outcomes with significantly higher deaths as compared to other procedure groups (p = 0.016). Radiological outcomes showed non-significant trend towards better outcomes in dynamic hip screw as compared to intramedullary nail (p = 0.08). CONCLUSION: Our 12 months follow-up data suggest that dynamic hip screw and total hip replacement have better clinical, functional outcomes followed by intramedullary nail. Hemiarthroplasty has fair-poor clinical and functional outcomes with significantly higher deaths as compared to other procedure groups.

Can alternate-day Statin regimen minimize its adverse effects on muscle and tendon? A systematic review.

OBJECTIVE: To review evidence-based data with respect to safety and efficacy of alternate-day statin therapy in dyslipidaemia compared to the standard daily dose. METHODS: The literature review was conducted at Aga Khan University Hospital, Karachi from July, 2016 to August, 2017. Electronic database search was carried out to compile available literature using PubMed, Excerpta Medica database and Google Scholar. The most relevant evidence-based research articles published over 10 years were selected. The latest search was dated August 03, 2017. RESULTS: A total of 2,074 articles were initially located. Alternate day statin regimen was reported in 53% of articles. Adverse effects on muscle and tendon were reported in 69% of articles. After scrutiny, 19(0.9%) studies covering alternate-day statin-mediated muscle and tendon disorders and 9(0.4%) studies encompassing the potential pathophysiological mechanisms of statin-associated muscle and tendon injury were selected. Except pravastatin and lovastatin, alternate-day statin therapy was almost as effective in lowering total cholesterol, low-density lipoprotein cholesterol and triglycerides as the daily dosing with low incidence of muscle toxicity and tends in opathy. CONCLUSIONS: Alternate-day statin regimen was found to be very well tolerated and might be an effective and safe remedy in clinical practice.

Analysing outcomes through orthopaedic trauma registry - A prospective cohort study.

OBJECTIVE: To develop a registry for recording injury-specific data to identify gaps and improve care. Methods: The prospective cohort study was conducted at Aga Khan University Hospital, Karachi, from June 2015 to July 2018 though enrollment of patients with limb trauma is continuing to date. Data on injuries and management related to Tibia shaft fractures was collected from medical records, and outcomes were assessed on follow-up visits. Internationally validated injury-specific scores were utilised for assessing functional, clinical and radiological outcomes. SPSS version 19 was used for data analysis. Results: There were 763 patients with 825 limb injuries. Of the injuries, 310(37.6%) related to upper limbs and 515(62.4%) to the lower limbs. Management was surgical for 741(89.9%) and conservative for 84(10.1%) injuries. Overall, 12(1.57%) patients died, and in 7(0.91%) cases mortality was unrelated to trauma and its management. There were 105 patients with tibia shaft fractures. Of them, 88(83.8%) were males and 17(16.2%) were females. At one-year follow-up excellent-to-good results were 12(92%) for intramedullary nailing followed by 7(78%) for open reduction and internal fixation. Conclusion: Registry data can be used to develop preventive strategies and to improve management protocols.

Therapeutic uses of pineapple-extracted bromelain in surgical care - A review.

Bromelain is an extract obtained from the pineapple plant and is used as a traditional folk remedy for several ailments. In this review, a comprehensive electronic database search was carried out to compile available literature on therapeutic implications of bromelain. Pharmaceutical value of bromelain has been demonstrated in different surgical sub-specialties. Diverse biological processes like anti-inflammatory, anti-oedematous, analgesic, anti-thrombotic, exfoliation etc. are involved in bromelain's therapeutic actions, mediated through the kallikrein-kinin and arachidonic acid pathways as well as through effects on cell mediated immunity. Bromelain equals non-steroidal anti-inflammatory drugs as an anti-inflammatory agent, but has been shown to have fewer side effects. In Europe it is approved for oral and topical use, mainly for surgical wounds, inflammation due to trauma and surgery, and debridement of deep burns. Literature suggests a promising role of bromelain in surgical care. More clinical trials to establish its utility as an anti-inflammatory agent in surgical care are recommended.

Trends in management of neck of femur fracture.

OBJECTIVE: To identify trends related to surgical procedure for the management of neck of femur fracture to see how the choice is changing over time in relation to different age groups. METHODS: The retrospective audit was conducted at Aga Khan University Hospital, Karachi, and comprised data of all patients who presented with neck of femur fracture from 1995 to 2014. Patients with open fractures and those having external fixators were excluded. Data was retrieved from the hospital database, and analysed using SPSS 17. RESULTS: Records of 1039 patients were reviewed. The proportion of patients in the 70+ years age group significantly increased from 45% to 52% over the two decades (p=0.033). Proportion of patients undergoing total hip replacement increased by more than 3 times from 2.6% to 8% (p<0.001).Internal fixation was the most common procedure in patients aged <50 (p<0.001), and hemiarthroplasty for those aged > 50 years (p<0.001). Total hip replacement was seen in its highest proportion (15%) in patients aged 40-49 years (p=0.006). Hemiarthroplasty showed a dramatic decrease in the age group 50-59 years (from 57% to 40%). Total hip replacement showed a steady increasing trend over the last 20 years, most prominently in people in their 50s and 60s (from 1% to 18%; p<0.001). CONCLUSIONS: There is apparently a rising trend in number of patients presenting with neck of femur fracture. Total hip replacement has a rising trend and partial hip arthroplasties have a decreasing trend when it comes to treatment of neck of femur fractures.

Calcaneal fractures: An audit of radiological outcome.

OBJECTIVE: To assess radiological outcome of management of calcaneal fractures. METHODS: The retrospective study was conducted at Aga Khan University Hospital, Karachi, and comprised data of calcaneal fractures managed between February , 2008 and February, 2014 Cases were identified through medical records, and X-rays were reviewed through digital radiology archive. Bohler\'s angle, Gissane\'s angle, calcaneal height and width were assessed digitally on pre-operative and post-operative X-ray images. RESULTS: Of the27 patients, only 1(3.7%) was female. The cause of fracture was fall from height 15(56%), road traffic accidents 7(26%) and bomb blasts5(19%). Tongue type fractures were 16(59%) and 11(41%) were joint depression type. There was a significant mean increase in Bohler\'s angle (p<0.001) and mean decrease in calcaneal width (p=0.023). Gissane\'s angle and calcaneal height increased marginally (p> 0.05 each). CONCLUSIONS: Measurable improvement in anatomical parameters is possible with surgery, which is a prerequisite for good functional results.
