Standardised Frailty Indicator as Predictor for Postoperative Delirium after Vascular Surgery:A Prospective Cohort Study

AbstractObjectivesTo determine whether the Groningen Frailty Indicator (GFI) has a positive predictive value for postoperative delirium (POD) after vascular surgery.MethodsBetween March and August 2010, 142 consecutive vascular surgery patients were prospectively evaluated. Preoperatively, the GFI was obtained and postoperatively patients were screened with the Delirium Observation Scale (DOS). Patients with a DOS-score ≥3 points were assessed by a geriatrician. Delirium was defined by the DSM-IV-TR criteria. Primary outcome variable was the incidence of POD. Secondary outcome variables were any surgical complication and hospital length of stay (HLOS) (>7 days).ResultsTen patients (7%) developed POD. The highest incidence of POD was found after aortic surgery (17%) and amputation procedures (40%). Increased comorbidities (p = 0.006), GFI score (p = 0.03), renal insufficiency (p = 0.04), elevated C-reactive protein (p = 0.008), high American Society of Anaesthesiologists score (p = 0.05), a DOS-score of ≥3 points (p = 0.001), post-operative intensive care unit admittance (p = 0.01) and HLOS ≥7 days (p = 0.005) were risk factors for POD. The GFI score was not associated with a prolonged HLOS. A mean number of 2 ± 1 (range 0–5) complications were registered. The receiver operator characteristics (ROC) area under the curve for the GFI was 0.70.ConclusionsThe GFI can be helpful in the early identification of POD after vascular surgery in a select group of high-risk patients

The management of tubo-ovarian abscess - A retrospective analysis of a centre offering outpatient intravenous antibiotic therapy

Background Tubo-ovarian abscess (TOA) carries long-term sequale in women of reproductive age. Consensus of the optimal treatment of tubo-ovarian abscess remains lacking. The aims of this study are to identify risk factors predicting the need for early drainage and compare clinical outcomes of current management practices of TOA. Methods From 2015 to 2019, a retrospective cohort study of 92 women admitted to a tertiary centre for gynaecological surgery was performed. Patients with diagnosed TOA were classified into two groups: treatment with antibiotics only, and those receiving additional drainage. Primary outcomes included length of hospital stay (LoS), length of antibiotic treatment (LoA) and need for re-intervention. Results In this study, 52 women (56.5%) were successfully treated with first line intravenous antibiotics; 40 (43.5%) received surgical drainage. Significant predictors for successful medical treatment only include age 35 years, pyrexia ≥ 38°C and a TOA size > 6cm may independently predict the need for drainage of TOA. Early identification of these patients is imperative for timely surgical intervention to avoid prolonged hospitalisation, antibiotic usage, and patient morbidity. More work is required to identify whether early drainage may reduce length of hospital stay and antibiotic treatment, including identifying certain patient groups who most likely to benefit from outpatient antibiotic intravenous therapy

Allergic Rhinitis and its Associated Co-Morbidities at Bugando Medical Centre in Northwestern Tanzania; A Prospective Review of 190 Cases.

Allergic rhinitis is one of the commonest atopic diseases which contribute to significant morbidity world wide while its epidemiology in Tanzania remains sparse. There was paucity of information regarding allergic rhinitis in our setting; therefore it was important to conduct this study to describe our experience on allergic rhinitis, associated co-morbidities and treatment outcome in patients attending Bugando Medical Centre. This was descriptive cross-sectional study involving all patients with a clinical diagnosis of allergic rhinitis at Bugando Medical Centre over a three-month period between June 2011 and August 2011. Data was collected using a pre-tested coded questionnaire and analyzed using SPSS statistical computer software version 17.0. A total of 190 patients were studied giving the prevalence of allergic rhinitis 14.7%. The median age of the patients was 8.5 years. The male to female ratio was 1:1. Adenoid hypertrophy, tonsillitis, hypertrophy of inferior turbinate, nasal polyps, otitis media and sinusitis were the most common co-morbidities affecting 92.6% of cases and were the major reason for attending hospital services. Sleep disturbance was common in children with adenoids hypertrophy (χ2 = 28.691, P = 0.000). Allergic conjunctivitis was found in 51.9%. The most common identified triggers were dust, strong perfume odors and cold weather (P < 0.05). Strong perfume odors affect female than males (χ2 = 4.583, P = 0.032). In this study family history of allergic rhinitis was not a significant risk factor (P =0.423). The majority of patients (68.8%) were treated surgically for allergic rhinitis co morbidities. Post operative complication and mortality rates were 2.9% and 1.6% respectively. The overall median duration of hospital stay of in-patients was 3 days (2 - 28 days). Most patients (98.4%) had satisfactory results at discharge. The study shows that allergic rhinitis is common in our settings representing 14.7% of all otorhinolaryngology and commonly affecting children and adolescent. Sufferers seek medical services due to co-morbidities of which combination of surgical and medical treatment was needed. High index of suspicions in diagnosing allergic rhinitis and early treatment is recommended

Acute lung injury in paediatric intensive care: course and outcome

Introduction: Acute lung injury (ALI) and acute respiratory distress syndrome (ARDS) carry a high morbidity and mortality (10-90%). ALI is characterised by non-cardiogenic pulmonary oedema and refractory hypoxaemia of multifactorial aetiology [1]. There is limited data about outcome particularly in children. Methods This retrospective cohort study of 85 randomly selected patients with respiratory failure recruited from a prospectively collected database represents 7.1% of 1187 admissions. They include those treated with High Frequency Oscillation Ventilation (HFOV). The patients were admitted between 1 November 1998 and 31 October 2000. Results: Of the 85, 49 developed acute lung injury and 47 had ARDS. There were 26 males and 23 females with a median age and weight of 7.7 months (range 1 day-12.8 years) and 8 kg (range 0.8-40 kg). There were 7 deaths giving a crude mortality of 14.3%, all of which fulfilled the Consensus I [1] criteria for ARDS. Pulmonary occlusion pressures were not routinely measured. The A-a gradient and PaO2/FiO2 ratio (median + [95% CI]) were 37.46 [31.82-43.1] kPa and 19.12 [15.26-22.98] kPa respectively. The non-survivors had a significantly lower PaO2/FiO2 ratio (13 [6.07-19.93] kPa) compared to survivors (23.85 [19.57-28.13] kPa) (P = 0.03) and had a higher A-a gradient (51.05 [35.68-66.42] kPa) compared to survivors (36.07 [30.2-41.94]) kPa though not significant (P = 0.06). Twenty-nine patients (59.2%) were oscillated (Sensormedics 3100A) including all 7 non-survivors. There was no difference in ventilation requirements for CMV prior to oscillation. Seventeen of the 49 (34.7%) were treated with Nitric Oxide including 5 out of 7 non-survivors (71.4%). The median (95% CI) number of failed organs was 3 (1.96-4.04) for non-survivors compared to 1 (0.62-1.62) for survivors (P = 0.03). There were 27 patients with isolated respiratory failure all of whom survived. Six (85.7%) of the non-survivors also required cardiovascular support.Conclusion: A crude mortality of 14.3% compares favourably to published data. The A-a gradient and PaO2/FiO2 ratio may be of help in morbidity scoring in paediatric ARDS. Use of Nitric Oxide and HFOV is associated with increased mortality, which probably relates to the severity of disease. Multiple organ failure particularly respiratory and cardiac disease is associated with increased mortality. ARDS with isolated respiratory failure carries a good prognosis in children

Geriatric Injuries among Patients Attending a Regional Hospital in Shinyanga Tanzania

Geriatric injuries pose a major challenge to surgeons and general practitioners in developing countries. The objective of this study was to determine the prevalence, injury characteristics and outcomes of geriatric injury among patients at Shinyanga Regional Hospital in Tanzania. Data was collected using a pre-tested, coded questionnaire and analyzed using SPSS computer system. A total of 94 geriatric trauma patients constituting 22.7% of all trauma admissions were studied. The male to female ratio was 1.4:1. Their mean age was 68.5 years (ranged 60-98 years). Premorbid illness was reported in 38.3% of patients. Most injuries were intentional in fifty-three (56.4%) patients. Assaults, falls and road traffic crashes were the mechanism of injuries in 52.1%, 19.1% and 11.7% of cases, respectively. The majority of cases of assault were females accounting for 64.6%. The majority of injuries (81.9%) occurred at home. Pre-hospital care was recorded in 5.3% of cases. The musculoskeletal (72.3%) and head (66.0%) regions were commonly affected. Soft tissue injuries (wounds) (89.4%) and fractures (52.2%) were the most common type of injuries. The majority of patients (90.4%) underwent surgical treatment of which wound debridement was the most common procedure performed in 91.8% of cases. Complication rate was 39.4%. The mean length of hospital stay was 28.6 days (ranged 1 – 124 days). The length of hospital stay was significantly longer in patients with co-morbidities, long bone fractures and those with complications (P<0.05). Mortality rate was 14.9% and it was significantly related to advanced age, presence of pre-morbid illness, high injury severity score, severe head injuries and the need for ventilatory support (P< 0.05). In conclusion, traumatic injuries in elderly constitute a major but preventable public health problem in Shinyanga region and contribute significantly to high morbidity and mortality. Urgent preventive measures focusing at the root causes of the injuries and early appropriate treatment is highly needed to reduce the occurrence, morbidity and mortality associated with these injurie
