Language-adaptive artificial intelligence: assessing CHATGPT'S answer to frequently asked questions on total hip arthroplasty questions.

ChatGPT is reported to be an acceptable tool to answer a majority of frequently asked patient questions. ChatGPT also converses in other languages including Urdu, which offers immense potential for the education of Pakistani patients. Therefore, this study evaluated ChatGPT's Urdu answers to the ten most frequently asked questions on Total Hip Arthroplasty, which were then rated by an expert. Out of 10 answers in English, 9 (90%) were satisfactory requiring minimal clarification and 1 (10%) was satisfactory requiring moderate clarification. In both Roman and Nastaliq script Urdu, 1 (10%) answer was satisfactory requiring moderate clarification, while 9 (90%) were unsatisfactory requiring substantial clarification. In conclusion, as opposed to ChatGPT English responses, Urdu responses were much less rigorous, generic, and lacked scientific rigor. We have a long way to go before Pakistani patients with limited English language skills could benefit from AI chatbots like ChatGPT.

A comprehensive exploration of artificial intelligence in orthopaedics within lower-middle-income countries: a narrative review.

Integrating Artificial Intelligence (AI) in orthopaedic within lower-middle-income countries (LMICs) promises landmark improvement in patient care. Delving into specific use cases-fracture detection, spine imaging, bone tumour classification, and joint surgery optimisation-the review illuminates the areas where AI can significantly enhance orthopaedic practices. AI could play a pivotal role in improving diagnoses, enabling early detection, and ultimately enhancing patient outcomes- crucial in regions with constrained healthcare services. Challenges to the integration of AI include financial constraints, shortage of skilled professionals, data limitations, and cultural and ethical considerations. Emphasising AI's collaborative role, it can act as a complementary tool working in tandem with physicians, aiming to address gaps in healthcare access and education. We need continued research and a conscientious approach, envisioning AI as a catalyst for equitable, efficient, and accessible orthopaedic healthcare for patients in LMICs.

Examining treatment targets and equity in bone-active medication use within secondary fracture prevention: a systematic review and meta-analysis.

PURPOSE: This systematic review seeks to evaluate the proportion of fragility fracture patients screened in secondary fracture prevention programs who were indicated for pharmacological treatment, received prescriptions for bone-active medications, and initiated the prescribed medication. Additionally, the study aims to analyze equity in pharmacological treatment by examining equity-related variables including age, sex, gender, race, education, income, and geographic location. METHODS: We conducted a systematic review to ascertain the proportion of fragility fracture patients indicated for treatment who received prescriptions and/or initiated bone-active medication through secondary fracture prevention programs. We also examined treatment indications reported in studies and eligibility criteria to confirm patients who were eligible for treatment. To compute the pooled proportions for medication prescription and initiation, we carried out a single group proportional meta-analysis. We also extracted the proportions of patients who received a prescription and/or began treatment based on age, sex, race, education, socioeconomic status, location, and chronic conditions. RESULTS: This review included 122 studies covering 114 programs. The pooled prescription rate was 77%, and the estimated medication initiation rate was 71%. Subgroup analysis revealed no significant difference in treatment initiation between the Fracture Liaison Service and other programs. Across all studies, age, sex, and socioeconomic status were the only equity variables reported in relation to treatment outcomes. CONCLUSION: Our systematic review emphasizes the need for standardized reporting guidelines in post-fracture interventions. Moreover, considering equity stratifiers in the analysis of health outcomes will help address inequities and improve the overall quality and reach of secondary fracture prevention programs.

Modified Frailty Index as a Predictor of Adverse Outcomes in Elective Primary Hip and Knee Replacement Surgery Patients at a Tertiary Care Hospital in Pakistan: A Cross-Sectional Study.

Objective The objective was to evaluate the modified frailty index as a predictor of early (within 30 days) postoperative complications in total joint arthroplasty patients, in a low middle-income country. Material and methods A cross-sectional study was carried out which included patients with ages ranging from 23 to 86 years, who underwent elective primary Total Hip or Knee Arthroplasties (TKA or THA) between December 2021 and February 2023. Modified frailty index (mFI-5) was calculated and 30-day morbidity and mortality were recorded. Post-operative complications were categorized as either surgical or medical and recorded. Results A total of 175 patients were included, amongst whom the majority were females (68.6%, n=120) and the mean age was 60.5 ± 13.2 years. 85 patients (48.6%) had a mFI-5 score of one while 48 patients (27.4%) had a score of two. Superficial surgical site infection was the most common complication overall in 6 patients (3.4%); however, no case of prosthetic joint infection was noted. Deep vein thrombosis (DVT) was the most common medical complication (1.7%, n=3). 5 patients (2.9%) required re-admission and two mortalities were recorded within the 30-day interval. A significant association was noted between post-operative surgical complications and mFI-5 score (p-value = < 0.001), with the risk of complications increasing with a higher mFI-5 score. Smoking was noted to be a risk factor for post-operative medical complications as well as 30-day mortality. Conclusion The current study shows that the mFI-5 index can effectively be used as a predictor of postoperative complications in the South Asian region such as Pakistan. This should be calculated routinely and can be used as a tool for pre-operative assessment and counseling.

Rate and Predictors of Patient Satisfaction After Total Joint Arthroplasty: A Cross-Sectional Study in a Low-to-Middle-Income Country.

Objective This study aimed to assess the rate of patient satisfaction after primary total joint arthroplasty (TJA) using a validated satisfaction measure. Materials and methods A cross-sectional study was conducted, including all patients who underwent primary TJA between December 2021 and February 2023. The age of the study population was found to range from 23 to 86 years. Patient satisfaction was assessed using a validated tool comprising four questions and a quality of life (QoL) question. Results A total of 197 patients were included, with a mean age of 60.9 ± 12.7 years. Total knee replacement (TKR) was performed in 124 patients (62.9%), and total hip replacement (THR) in 73 patients (37.1%). The mean patient satisfaction score was 86.6 ± 14.4 out of a maximum of 100. A significant negative correlation was observed between the Charlson Comorbidity Index (CCI) and the overall satisfaction score (p-value = 0.029). The majority of the patients (52.3%, n = 103) answered that their QoL had greatly improved, and a similar level of improvement was noted in elderly vs. adult patients (p-value = 0.17). A significantly higher proportion of male patients reported improvement more than they ever expected compared to female patients, the majority of whom reported their QoL was greatly improved (p-value = 0.025). Conclusion Total joint arthroplasty has been shown to achieve good patient satisfaction and an improvement in QoL. However, an increased comorbidity index and female gender were identified as factors for reduced satisfaction. Hence, it is recommended to consider these factors and counsel patients accordingly based on local patient data.

Orthopaedic Surgery Complications at a Tertiary Care Hospital in a Low- and Middle-Income Country: A National Surgical Quality Improvement Project Analysis.

BACKGROUND: Through a comparison of orthopaedic surgical procedures performed at a tertiary care hospital in Pakistan with other participating hospitals of National Surgical Quality Improvement Project (NSQIP), we aim to identify the areas of orthopaedic surgical care at our center that need improvement and also those which are at par with international standards. METHODS: The study analyses orthopaedic surgeries at a tertiary care hospital in Pakistan using NSQIP registry to compare complication rates with other American College of Surgeons-NSQIP participant hospitals. Two reviewers collect data in different days every 8 days to reduce bias, and the results are reported in odds ratios using quarterly reports. This study included 584 eligible orthopaedic cases performed in 2021. Yearly institutional reports with odds ratios were also used to identify areas needing improvement and to implement changes to improve orthopaedic surgical outcomes at said institute. RESULTS: The quarterly reports suggest a relatively higher OR for certain indicators such as cardiac events, surgical site infection, mortality, and morbidity throughout. The renal failure rate was very high in the third and fourth quarters with odds ratios of 4.57 and 10.31, respectively. However, the official NSQIP annual institutional report for 2021 identified sepsis, surgical site infections, and cardiac complications as areas 'needing improvement'. It also indicated that the hospital performed exemplarily when it came to venous thromboembolism (VTE). As for the rest of the indicators, the hospital fell in the 'as expected' category of the NSQIP standards. CONCLUSION: This initial report helps the hospital's orthopaedic department in recognizing areas for improvement and making system-level changes to improve patient outcomes. The implementation of these interventions has yielded favorable outcomes, as evidenced by the findings in the NSQIP yearly report for 2022. Reinforcements and measures are needed to be taken to reduce the adverse events even further and to improve the patient outcomes and quality.

Diabetic Foot Ulcers: Contemporary Assessment And Management.

Diabetic foot ulcer disease is the combination of vasculopathy, neuropathy and infection. It is important to identify the main aetiology and to treat it for optimal ulcer healing so that limb amputation may be prevented. A literature review spanning five years (2018-2021) was performed to assess the current understanding of these aetiologies and management options for their treatment. Peripheral artery disease is prevalent in patients with diabetes. Before performing any amputations, whether minor or major, vascular supply in these patients needs to be evaluated and, if needed, improved. Diabetic neuropathy is a long-term complication of uncontrolled diabetes. Patients' education is very important with respect to selfcare and prevention of foot complications arising out of minor trauma in diabetic population. Better foot care and regular use of off-loading shoe wear can prevent neuropathic diabetic foot ulcers. Infection in diabetic patients is mostly polymicrobial and it can present as superficial or deep infections. Early diagnosis, use of broad-spectrum antibiotics, and aggressive debridement, when needed, is advocated to prevent foot amputation. Contemporary treatment armamentarium provides many options for treating diabetic foot ulcers. Nevertheless, one must exhaust all preventive strategies to avoid ulcers in the first place. Once an ulcer has developed, it should be managed aggressively with appropriate soft tissue and, if required, with bony procedures. The current narrative review was planned to explore the current understanding about the main aetiologies of diabetic foot ulcers and about the available treatment options.

GRADE-ADOLOPMENT of clinical practice guideline for postmenopausal osteoporosis management-a Pakistani context.

Due to its high prevalence, we aimed to create postmenopausal osteoporosis clinical practice guideline via GRADE-ADOLOPMENT for Pakistan. We recommend a higher dose (2000-4000 IU) of vitamin D for osteoporotic patients who are old, have malabsorption, or are obese. The guideline will help standardize care provision and improve health care outcomes for osteoporosis. PURPOSE: Postmenopausal osteoporosis affects one in every five postmenopausal women in Pakistan. An evidence-based clinical practice guideline (CPG) is needed to standardize care provision to optimize health outcomes. Hence, we aimed to develop CPG for the management of postmenopausal osteoporosis in Pakistan. METHODS: The GRADE-ADOLOPMENT process was used to adopt (as is or with minor changes), exclude (omit), or adapt (modify based on local context) recommendations to the source guideline (SG)-clinical practice guidelines for the diagnosis and treatment of postmenopausal osteoporosis-2020 update from American Association of Clinical Endocrinology (AACE). RESULTS: The SG was "adoloped" to cater to the local context. The SG consisted of 51 recommendations. Forty-five recommendations were adopted as is. Due to unavailability of drugs, 4 recommendations were adopted with minor changes, and one was excluded, while one recommendation was adopted with the inclusion of use of a surrogate FRAX tool specific for Pakistan. One recommendation regarding vitamin D dosage was adapted to recommend a dose of 2000-4000 IU of vitamin D in patients with obesity, malabsorption, and old age. CONCLUSION: The developed Pakistani postmenopausal osteoporosis guideline consists of 50 recommendations. The guideline created recommends a higher dose (2000-4000 IU) of vitamin D for patients who are old, have malabsorption, or are obese, which is an adaptation from the SG by the AACE. This higher dose is justified as lower doses prove to be suboptimal in these groups and should be complemented with baseline vitamin D and calcium levels.

Thirty-Day Morbidity and Mortality After Total Knee Replacement in a Tertiary Care Hospital in Pakistan.

Background Total knee arthroplasty has become very popular globally as a safe surgical modality for relieving pain and improving functional outcomes in patients who fail to respond to conservative treatments; however, it may be associated with postoperative complications. The aim of this study is to determine the incidence of postoperative complications occurring within the first 30 days after total knee replacement (TKR). Materials and methods This is a prospective cross-sectional study. All consecutive patients who underwent primary unilateral or bilateral total knee arthroplasty between November 2020 and July 2021 were included in the study. Patients were followed for a period of 30 days, and postoperative complications (if any) were documented. Continuous variables were expressed as means ± standard deviations. Categorical variables were expressed as frequency and percentages, and chi-square test was used to compare the qualitative variables. Univariate and multiple logistic regression analyses were done to analyze the magnitude of associations of the complication with other predictor variables keeping a level of significance of <0.05. Results The overall complication rate within the 30-day window was 7.0%. Postoperative surgical site infections (SSI) were noted in three patients (2.6%). Thromboembolic complications were seen in only one patient (0.9%). One patient (0.9%) was readmitted within the one-month period after initial discharge, and one patient (0.9%) expired within 12 hours postoperatively. Conclusion TKR renders satisfactory results with a low incidence of complications in general; however, wound infections, thromboembolic complications, and cardiovascular complications do occur postoperatively. Male gender, obesity, and bilateral TKRs remain the notable risk factors for the development of complications post-procedure.

Prevention of falls in hospital: Audit report from a Tertiary care hospital of Pakistan.

OBJECTIVE: The study aims to assess the fall incidents in past 5 years and fall assessment practices at the Aga Khan University Hospital, Karachi. METHODS: We performed a single-center retrospective audit at Aga Khan University Hospital from October 2019 to December 2019. A list of all patients admitted to Aga Khan University Hospital under the Musculoskeletal and Sports Medicine Service Line was obtained using the Hospital Information Management System (HIMS) from Jan 2017 to June 2018. Data including fall assessment scores was collected retrospectively from medical record files. RESULTS: A total of 1499 patients were admitted during this time period, of whom 5 patients had a fall incident during their hospital stay. The mean Morse Scale scores of patients who had a fall was 50 ±16 whereas, patients with no fall incidence had mean score of 31±22. Fall assessment was documented in nursing notes for 100% of the patients. CONCLUSIONS: Our findings show that fall policy is implemented strictly within our hospital. In order to reduce the risk of a fall further, more in-depth assessment of high risk patients with involvement of physicians and physiotherapists earlier on in the process for high risk patients may be beneficial.

Bridging the gaps in secondary fracture prevention at a single center in Pakistan-compliance with the IOF best practice framework.

PURPOSE: The International Osteoporosis Foundation (IOF) formulated a set of best practice framework as an international benchmark for secondary fracture prevention (SFP) and fracture liaison services (FLS), delineating essential elements of service delivery. The aim of this audit was to assess compliance with the IOF standards for patients ≥ 50 years presenting with fragility hip fractures at a tertiary care center in Pakistan. METHODS: A retrospective sample of hip fracture cases from Jan 2019 to Dec 2019, treated at the section of Orthopedic Surgery, Aga Khan University, Karachi, was conducted. After excluding high energy trauma cases and patients younger than 50 years of age, medical records were audited, using a pre-structured Performa based on IOF standards. Compliance level of 0, 1, 2, and 3 was recorded as defined by IOF. Microsoft excel was used for data analysis. RESULTS: A compliance level of 3 was recorded for patient identification and fall prevention services, whereas level 1 was attained for database maintenance for 25 (100%) cases. For medication initiation, level 0 was recorded for all the cases; however, 8 (32%) cases were prescribed calcium and vitamin D supplements. For the standards, including post-fracture assessment timing, evaluation of secondary causes of osteoporosis, multifaceted assessment, medication review, communication strategy, and long-term management, a level 0 was noted for 25 (100%) cases. Moreover, no recommended assessment guidelines were followed uniformly. CONCLUSION: The care gaps identified require substantial efforts to ensure adequate implementation of the overall best practice standards for SFP, necessitating the need for FLS initiation and establishment of fracture care pathway.

Gum Chewing, Added to Conventional Feeding, Reduces Risk of Post-Operative Ileus after Elective Hip and Knee Arthroplasty Procedures in Elderly Population: A Protocol for a Parallel Design, Open-Label, Randomized Controlled Trial.

INTRODUCTION: Postoperative ileus (poi) is defined as a temporary cessation of bowel movement after a surgical procedure. Cessation of bowel movement not only leads to disturbing constipation but also may lead to nausea, loss of appetite, and food intolerance. Literature reports "sham feeding" (gum-chewing) effect as an increase in chewing and saliva which enhances the gastric emptying and overall motility of gut as a cephalic phase of digestion. Therefore, we aim to assess the effect of adding gum-chewing to the conventional postoperative feeding regimen on restoring postoperative bowel function and length of stay in hospital of patients undergoing elective hip arthroplasty. METHODS AND ANALYSIS: This is a single-center, open-label, parallel design, superiority randomized-controlled trial with 2 treatment arms. The primary and secondary outcomes will be the time interval in hours from the end of surgery until the passage of flatus and the time interval in hours from the end of surgery until the passage of stool. Statistical analysis will be done using STATA software. Length of stay will be calculated by Kaplan-Meier analysis, with unadjusted comparison of groups by Mantel-Cox log rank test. Risk ratios for the time-to-become ileus free and time-to-discharge from hospital will be calculated by Cox regression modeling. P value as 0.05 or less will be taken as significant. ETHICS AND DISSEMINATION: This protocol is exempted from Ethical review at this stage however all the required approvals will be taken from the ethical review committee before starting the study. Informed consent will be taken form the patient to enroll him/her in the study. Results of the study will be disseminated to the study participants, public health, and clinical professionals. The results would also be published in a reputable international journal. TRIAL REGISTRATION: This trial is registered on clinicaltrials.gov with ID: NCT04489875. HIGHLIGHTS: Cessation of bowel movement not only leads to disturbing constipation but also may lead to nausea, loss of appetite, and food intolerance.These patients tend to have more pain scores and dissatisfaction with the surgical management and team.The "sham feeding" (gum-chewing) effect causes an increase in chewing and saliva formation and therefore enhances the gastric emptying and overall motility of gut as a cephalic phase of digestion even in non-gastro or colorectal surgeries.We hypothesize that there is an association between gum chewing and the relief from postoperative ileus in hip arthroplasty patients.

Comparison of Surgical Site Infection After Skin Closure by Prolene or Staples in Bilateral Simultaneous Knee Arthroplasty Patients: A Parallel Design Randomized Controlled Trial Protocol.

INTRODUCTION: Knee arthroplasty also known as the total knee replacement is an orthopedic surgical procedure done to resurface the knee that has been severely damaged by arthritis. After the completion of the surgical procedure, the skin closure is done. The optimal goal of skin closure after the procedure is to promote rapid healing and an acceptable cosmetic result while minimizing the risk of infection. Skin closure after knee arthroplasty is done by using either of the two widely used sutures i.e., polypropylene (Prolene) sutures or the skin staple sutures. There are no standard guidelines as which type of the suture should be used. The present study aims to compare the incidence of surgical site infections (superficial and deep) for Prolene vs staple sutures in the bilateral knee arthroplasty patients within 6 weeks for superficial and within 90 days for deep infection. METHODS: This study will be conducted as an open blinded, parallel design, equivalence randomized controlled trial. The patients would be selected and randomized in 1:1 ratio to receive either of the two interventions i.e., Prolene or Staples. Patients undergoing unilateral or staged total knee replacement (TKR) were excluded. ANALYSIS: The normality assessment will be done using Shapiro Wilk test. Cox proportional hazard regression will be used to check the univariate and multi-variable associations of independent variables with the outcome. Both intention to treat analysis and per protocol analysis would be performed. ETHICS AND DISSEMINATION: All the required approvals will be taken from the ethical review committee. Informed consent will be taken form the patient to enroll him/her in the study. Results of the study will be disseminated to the study participants, public health and clinical professionals and would also be published in a reputable international journal.The trial is registered at clinicaltrials.gov and UIN of the registry is NCT04492852. HIGHLIGHTS: Post-operative surgical site infections and complications are a major concern nowadays.Skin staples are not widely used as compared to Prolene because they are expensive and not easily available in every hospital.There are no standard guidelines as which type of the suture should be used.The type of sutures is being selected on the orders and wishes of the surgeon at the time of skin closure.

Does more testing in routine preoperative evaluation benefit the orthopedic patient? Case control study from a resource-constrained setting.

BACKGROUND: Routine preoperative tests in healthy patients not only cause extra anxiety, but may delay treatment without influencing surgical plan. This has worse impact in resource-constrained settings where fee for service rather than health insurance is the usual norm. Investigators aim to determine if "routine" pre-operative tests are justified in healthy orthopedic patients. METHODS: We conducted a non-commercialized, non-funded matched case control study in tertiary care university hospital and a level-1 trauma centre for healthy patients (ASA-1&2) admitted from January 2014-December 2016 for elective orthopedic intermediate and major procedures. Cases (patient who had a change in his/her surgical plan after admission) and controls were selected independently of the exposure of interest then matched randomly to cases on age, gender and procedure type. Primary exposure was the routine preoperative lab tests, as defined by the American Society of Anesthesiologist, which included 13 blood tests. Analysis was done using Principle Component Analysis and Conditional logistic regression at univariate and multivariable levels reporting matched adjusted Odds Ratios. The data was reported in line with STROCSS criteria. RESULTS: Overall, 7610 preoperative tests were done for 670 patients with 62% men among cases and 53% men among controls with mean age of 49.9 ± 22.5 years and 41.1 ± 23.0 years, respectively. There were 1076 (14%) abnormal result that influenced surgical plan in 0.96% cases only. Matched adjusted OR with 95% confidence interval of primary exposure was insignificant. CONCLUSION: Routine preoperative tests were superfluous and did not influence the surgical plan when adjusted for other variables in the model as well as after matching on potential confounders. This study would be amongst first steps to move towards an evidence based surgical practice for preoperative evaluation.

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 .

Outcomes of total hip arthroplasty using dual-mobility cups for femoral neck fractures: a systematic review and meta-analysis.

OBJECTIVES: Femoral neck fractures (FNFs), with up to 15% mortality, are prominent orthopaedic emergencies. After treating FNFs, dislocation is another challenge increasing morbidity, mortality and treatment costs substantially. The emerging dual-mobility cup (DMC) may decrease dislocation rates following total hip arthroplasty (THA) for FNFs. We performed a systematic review of literature reporting dislocation and mortality rates with DMC-THA for the treatment of FNFs. METHODS: 2 authors independently searched PubMed (MEDLINE), Google Scholar and Cochrane library for studies reporting dislocation and mortality rates for FNFs treated with DMC-THA since inception up to January 2019. Data on outcomes of interest was extracted from all studies and assessed for eligibility for a meta-analysis. RESULTS: Out of 522 search results, 18 studies were included in the systematic review and 4 in the meta-analysis. The mean rate of dislocation following DMC-THA for FNFs was found to be 1.87% ± 2.11, with a 1-year mortality rate of 14.0% ± 10.55. Results of meta-analysis showed that dislocation and 1-year postoperative mortality rates were significantly lower for DMC-THA with a risk ratio 0.31 (95% CI, 0.16-0.59; I2 = 0%, p = 0.0003) and 0.55 (0.40, 0.77; I2 = 0%, p = 0.003) respectively when compared to biploar hemiathroplasty (BHA). CONCLUSIONS: The mean dislocation and mortality rates in DMC-THA are lower than previously reported rates for THA with single cup and comparable to unipolar and bipolar hemiarthroplasty. Further research involving randomised control trials to assess differences in outcomes, longevity and cost-effectiveness needs to be conducted to make recommendations for the use of DMC in treating FNFs.

Does early surgery prevent Postoperative ICU admission after surgery for the fracture of the hip. Nested case control study of 911 patients.

INTRODUCTION: Since most hip fractures are treated surgically, it is imperative to find an optimum fracture-to-surgery time to decrease the potential complications and enhance postoperative outcomes. In comparison to the vast plethora of literature available on surgical delay and its implications on mortality, very little, if any, research is available on the impact of delayed surgery on postoperative ICU admission. The primary objective of our study is to examine the factors influencing post-surgical ICU admission in order to work on preventive strategies to reduce the potential associated morbidity. MATERIAL AND METHODS: Investigators did a nested case control study in a university hospital. A case was defined as a patient who had postoperative ICU admission while controls were patients who did not have postoperative ICU admission after hip fracture surgery. The primary outcome variable was postoperative ICU admission. The exposure variable was defined as the time to surgery which was categorized into two categories; early and late; the early surgery included patients who were operated within ≤ 48 h and the late included patients who had their surgery >48 h. Information on potential confounders including age, type of the procedure and comorbidities were also obtained. Result reported in-line with STROCSS criteria. RESULTS: A total cohort of 1084 hip fracture surgeries were performed from January 2010 to December 2018. After screening for eligibility criteria, 911 patients were eligible for the final simple logistic regression analysis (48 cases and 863 controls). Our exposure variable i.e. time from admission to surgery showed no difference between cases and controls. The odds of being treated with Hemiarthroplasty among cases admitted in ICU was 2.42 times as compared to controls (aOR = 2.42; 95% C.I. 1.21-4.86). CONCLUSION: Our study did not find an association between surgical delay and post-operative ICU admission after accounting for other covariates and potential confounders.

Change in the spectrum of orthopedic trauma: Effects of COVID-19 pandemic in a developing nation during the upsurge; a cross-sectional study.

BACKGROUND: The COVID-19 pandemic has caused a great impact on orthopedic surgery with a significant curtailment in elective surgeries which is the major bread and butter for orthopedic surgeons. It was also observed that the spectrum of orthopedic trauma injuries has shifted from more severe and frequent road traffic accidents (high energy trauma) to general, low energy house-hold injuries like low energy fractures in the elderly, pediatric fractures, house-hold sharp cut injuries and nail bed lacerations. The aim of this study is to appraise the effect of the COVID-19 pandemic on orthopedic surgical practice, both inpatient and outpatient facility. MATERIALS AND METHODS: This is a retrospective cross sectional study conducted in a tertiary care teaching hospital. We collected data of patients admitted from February 1, 2020 to 30th April 2020 in the orthopedic service line using non-probability consecutive sampling. This study population was divided into pre-COVID and COVID eras (6 weeks each). The data included patient demographic parameters like age, gender and site of injury, mechanism of injury, diagnosis and procedure performed and carrying out of COVID-19 Polymerase Chain Reaction (PCR) test in the COVID-era. RESULTS: We observed that outpatient clinical volume decreased by 75% in COVID era. Fifty percent of surgical procedures decreased in COVID era as compared to pre-COVID era. Trauma procedures reduced by 40% in COVID era. Most common mechanism of injury was household injuries like low energy falls. A significant reduction in elective surgeries by 67% was observed in the COVID era. CONCLUSION: The impact of COVID-19 pandemic has significantly changed the spectrum of orthopedic injury. More household injuries have occurred and are anticipated due to the ongoing effects of lockdown.
