The chlamydia care cascade of young people attending Australian general practices; a descriptive study to assess gaps in care.

BACKGROUND: Most chlamydia infections in Australia are diagnosed in general practice. The care cascade concept (testing, treatment and re-testing) can be utilised to explore the management of chlamydia infections. We explored the chlamydia care cascade among young people attending general practices in Australia. METHODS: We analysed de-identified electronic medical record data for 16-29-year-old individuals attending 70 Australian general practices between January 2018 and December 2020. Five outcomes: (1) chlamydia testing, (2) positivity, (3) treatment, (4) re-testing and (5) re-infection were summarised as annual counts and proportions per calendar year. Logistic regression was used to investigate the association of age, gender and clinic location with each outcome. RESULTS: During the study period, a total of 220909 clinical episodes involving 137358 16-29-year-olds were recorded. Of these episodes, 10.45% (n =23077, 95% CI 8.73-12.46) involved a chlamydia test. Of 1632 chlamydia cases, 88.79% (n =1449, 95% CI 86.37-90.82) had appropriate antibiotics recorded as defined in Australian sexually transmitted infection management guidelines. Of 183 chlamydia cases that did not have appropriate antibiotics recorded, 46.45% (n =85) had re-attended the clinic within 90days of diagnosis. Among 1068 chlamydia cases that had appropriate antibiotic recorded in 2018 and 2019, 22.57% (n =241, 95% CI 20.15-25.18) were re-tested within 6weeks to 4months of their diagnosis. One-third of episodes of chlamydia cases that did not have a re-test recorded (n =281) had re-attended the clinics within 4months of diagnosis. CONCLUSION: Our study provides insight into chlamydia management by analysing general practice medical records, indicating substantial gaps in testing and re-testing for 16-29-year-olds. These data can also be used to explore the impact of future interventions to optimise chlamydia management.

Prevalence of mental disorders in a Greek island.

In Greece, the need for epidemiological data became evident at the beginning of the mental health reform during 1983 with the emergence of the necessity to develop community-based mental health services. This survey was conducted in 2005 by the Association for Regional Development and Mental Health (EPAPSY), supported by the local authorities. It followed the methodology of the survey "Mental Health in the General Population: Images and Realities" (MHGP), a large scale multisite epidemiological research conducted by the World Health Organization Collaborative Centre of Lille in France and other countries. The aim of this study was to assess prevalence, sociodemographic and comorbidity patterns of mental disorders in the general adult population of Evia Island, Greece. This was a cross-sectional survey investigating point, period and lifetime prevalence of mental disorders. The target population was the non-institutionalized adult population of island of Evia (population 230,000 people). The Mini International Neuropsychiatric Interview and a sociodemographic data questionnaire were administered by trained interviewers to 900 residents of Evia. The quota sampling method was used to obtain a sample representative of the target population. Lifetime prevalence of any disorder, as identified by the MINI, was 29%. The prevalence of depression was high, with 17.5% of women and 14.6% of men currently meeting the criteria for diagnosis. Affective and anxiety disorders were found to be more frequent in women than men, except for dysthymia, social phobia and post-traumatic stress disorder which were slightly more frequent in men. The prevalence of psychiatric disorders in Evia was much higher than the prevalence found by other epidemiological studies in Greece and among the highest in Southern Europe. The high prevalence of mental disorders found in Evia means that almost one third of the population will suffer from a clinically significant disorder in their lifetime. Therefore, the resulting social burden is very relevant and requires the inclusion of mental health care among the main goals of a public health strategy. Methodological issues concerning the comparison of results between different countries, the limitations of the study and the rates of alcohol use disorders discussed. High rates of mental disorders are related to demographic changes, such as the increasing are size of elderly population, and probably to economic hardship and rise in unemployment. Results should be taken into consideration for the planning and development of interventions for vulnerable groups.

The effects of oral garlic on vaginal candida colony counts: a randomised placebo controlled double-blind trial.

OBJECTIVE: Garlic is effective against Candida species in vitro, and along with other alternative therapies, is used by women with vulvovaginal candidiasis. The objective of this study was to ascertain whether oral garlic reduced vaginal candida counts during the second half of the menstrual cycle in asymptomatic women colonised with Candida species. DESIGN: A simple randomised double-blinded controlled trial. SETTING: Melbourne, Australia. SAMPLE: Sixty-three asymptomatic women who were culture-positive for Candida species at screening. METHODS: Participants were randomised to three garlic tablets or placebo orally, twice daily, for 14 days. MAIN OUTCOME MEASURES: The primary outcome was the proportion of women with colony counts of candida >100 colony-forming units per ml in any given day during the last 7 days before menstruation, defined as a 'case'. Secondary outcomes included the mean quantitative colony counts of candida over 14 days prior to menses. RESULTS: There was no evidence of a difference between the proportion of cases in the garlic and placebo groups (76 versus 90%; relative risk, RR 0.85; 95% confidence interval, 95% CI 0.67-1.08), in the mean colony counts in both groups (ratio of geometric means of candidal colony counts 0.63; 95% CI 0.39-10.03; P = 0.74), or difference in the number of women reporting abnormal vaginal symptoms during the 2 weeks before menstruation (RR 1.03; 95% CI 0.67-1.58; P = 0.91). The garlic group reported more adverse effects (83% compared 43% in the placebo group; difference in proportions 39%; 95% CI 17-%; P < 0.01). CONCLUSIONS: This study provided data for sample size calculations in future studies on the antifungal effect of garlic, but provided no evidence to inform clinical practice regarding the use of garlic in vaginal candidiasis. Further studies might investigate longer courses or topical formulations.

Factors associated with ownership and use of written asthma action plans in North-West Melbourne.

PURPOSE: Written asthma action plans (WAAPs) have become a core component of asthma management in Australia. We investigated ownership, utilisation and factors associated with ownership of asthma action plans by caregivers. METHODS: 443/776 (57%) caregivers of children aged 2-14 years with asthma were identified from 32 GP clinics as part of a randomised controlled trial (RCT), and completed self-administered questionnaires. RESULTS: Only 29% of participants owned a WAAP, while 13% possessed verbal instructions, and 56% had no plan. An asthma action plan for children, which was developed by a general practitioner (GP) was more likely to comprise verbal instructions (p = 0.001), while action plans developed by paediatricians were more likely to be written (p < 0.001). Just over one half of caregivers (59%) reported discussing their child's action plan the last time they visited their doctor for asthma. Factors associated with WAAP ownership included nights waking (p = 0.013), self reported severity (p = 0.001), and days lost from school (p = 0.037). Children who had seen a GP in the last 3 months for asthma, or who had been to the Emergency Department (ED) or hospital were more likely to possess a WAAP (p < 0.001). Caregivers who were less satisfied with their child's asthma control were more likely to own a WAAP (p = 0.037). Caregivers with any action plan found it useful and 82% reported using their action plan for management of an acute attack. However, caregivers with a WAAP were more likely to adhere to the plan for an acute attack compared to caregivers with verbal instructions (OR = 4.5, p < 0.05). Caregivers with a WAAP were more knowledgeable about asthma (p = 0.002), better able to recognise the difference between preventer and reliever medications (p = 0.01), and better able to recognise an asthma attack (p = 0.006). CONCLUSIONS: Ownership of WAAPs in this group was still too low. Importantly, caregivers with written instructions were more knowledgeable about asthma and more likely to report following the action plan during an asthma attack.

Australian doctors and their postgraduate qualifications.

BACKGROUND: A key activity for doctors is lifelong learning. This may be as part of professional development, vocational registration, formal postgraduate study, e.g. university diplomas and degrees, or vocational training which leads to fellowship of a professional college. However, there are significant barriers of time and cost that prevent many doctors from participating in lifelong learning. METHOD: We examined the range of basic and postgraduate qualifications held by a representative sample of 1198 doctors provided by the HIC of Australian doctors. DISCUSSION: Significant numbers of general practitioners practise without a formal postgraduate qualification in general practice, unlike our specialist colleagues. However, postgraduate studies are undertaken in a variety of other formats and qualifications.

Reliability of the Melbourne assessment of unilateral upper limb function.

This study examines the reliability of the Melbourne Assessment of Unilateral Upper Limb Function: a quantitative test of quality of movement in children with neurological impairment. The assessment was administered to 20 children aged from 5 to 16 years (mean age 9 years 10 months, SD 2 years 10 months) who had various types and degrees of cerebral palsy (CP). The performances of the 20 children during assessment were videotaped for subsequent scoring by 15 occupational therapists. Scores were analyzed for internal consistency of test items, inter- and intrarater reliability of scorings of the same videotapes, and test-retest reliability using repeat videotaping. Results revealed very high internal consistency of test items (alpha=0.96), moderate to high agreement both within and between raters for all test items (intraclass correlations of at least 0.7) apart from item 16 (hand to mouth and down), and high interrater reliability (0.95) and intrarater reliability (0.97) for total test scores. Test-retest results revealed moderate to high intrarater reliability for item totals (mean of 0.83 and 0.79) for each rater and high reliability for test totals (0.98 and 0.97). These findings indicate that the Melbourne Assessment of Unilateral Upper Limb Function is a reliable tool for measuring the quality of unilateral upper-limb movement in children with CP.

The effect of flexible low glycemic index dietary advice versus measured carbohydrate exchange diets on glycemic control in children with type 1 diabetes.

OBJECTIVE: To determine the long-term effect of low glycemic index dietary advice on metabolic control and quality of life in children with type 1 diabetes. RESEARCH DESIGN AND METHODS: Children with type 1 diabetes (n = 104) were recruited to a prospective, stratified, randomized, parallel study to examine the effects of a measured carbohydrate exchange (CHOx) diet versus a more flexible low-glycemic index (GI) dietary regimen on HbA(1c) levels, incidence of hypo- and hyperglycemia, insulin dose, dietary intake, and measures of quality of life over 12 months. RESULTS: At 12 months, children in the low-GI group had significantly better HbA(1c) levels than those in the CHOx group (8.05 +/- 0.95 vs. 8.61 +/- 1.37%, P = 0.05). Rates of excessive hyperglycemia (>15 episodes per month) were significantly lower in the low-GI group (35 vs. 66%, P = 0.006). There were no differences in insulin dose, hypoglycemic episodes, or dietary composition. The low-GI dietary regimen was associated with better quality of life for both children and parents. CONCLUSIONS: Flexible dietary instruction based on the food pyramid with an emphasis of low-GI foods improves HbA(1c) levels without increasing the risk of hypoglycemia and enhances the quality of life in children with diabetes.

The effect of botulinum toxin type A and a variable hip abduction orthosis on gross motor function: a randomized controlled trial.

Hip displacement is the second most common deformity after equinus in children with cerebral palsy (CP), and may result in dislocation, pain, fixed deformity and loss of function. We studied the combined effects of intramuscular injections of botulinum toxin type A (BTX-A) to the adductors and hamstrings and a variable hip abduction orthosis (SWASH), on gross motor function, hip displacement and progression to surgery, in a randomized clinical trial. Thirty-nine children, with bilateral spastic cerebral palsy, and mean age 3 years + 2 months (range 1 year+7 months--4 years +10 months) entered the trial. Gross Motor Function Classification System (GMFCS) levels were as follows: one child was level II, 11 were level III, 13 were level IV and 14 were level V. After concealed randomization, 20 were allocated to the control group and 19 to the intervention group. Thirty-five children completed the follow up at 1 year. The novel intervention group received up to 4.0 U BOTOX/kg/muscle, 16 U/kg/body weight every 6 months plus the use of a SWASH brace. The control group received clinical best practice comprising physiotherapy but no hip abduction bracing. Both groups showed improvements in total Gross Motor Function Measure (GMFM) score [mean 6.0% BTX-A group; 6.1% Control; 95% CI -- 6.7, 6.5 (NS)], however, there was no additional treatment effect for the study group. There were similar improvements on GMFM goal scores and GMFM-66 scores, but again no additional treatment effect was observed. Multiple regression of change in total GMFM by GMFCS classification for each group showed greater improvement in the total scores from baseline in the BTX-A/SWASH treated group than the control group. In the first year, nine children (two in the intervention group and seven in the control group) required soft tissue surgery because of progressive hip migration in excess of 40%. A longer-term follow up of a larger cohort may be required to determine the effect of the combined treatment on hip displacement.

Laparotomy for necrotizing enterocolitis: intensive care nursery compared with operating theatre.

OBJECTIVE: To determine whether neonates requiring laparotomy for necrotizing enterocolitis (NEC) are more stable perioperatively and have less disruption of physiological parameters if surgery is performed in the neonatal intensive care unit (NICU) compared with the operating theatre (OR). METHODOLOGY: A retrospective case review was performed on 233 neonates referred for further surgical management of severe NEC in the period January 1989 to December 1997. Mortality and morbidity were compared by calculating the score for neonatal acute physiology (SNAP) and its attendant risk of mortality score. Thirty-six separate physiological variables were also compared pre- and postoperatively and the mean postoperative change was calculated. RESULTS: For neonates weighing less than 1500 g, mortality was linked to illness severity, as measured by SNAP, rather than operative location. Specific adverse events associated with secondary transfer to the OR included hypothermia, deterioration in oxygenation parameters, ventilation parameters and platelet count. The liberal use of blood products, albumin and bicarbonate in perioperative resuscitation may have obscured other effects. CONCLUSIONS: The use of the neonatal intensive care nursery for surgery on neonates weighing less than 1500 g with severe NEC can be justified and such use should be encouraged. In contrast, secondary transport of neonates weighing less than 1500 g to the OR for laparotomy is associated with significant deterioration in a number of physiological parameters, which may impact on morbidity.

Does an early postnatal check-up improve maternal health: results from a randomised trial in Australian general practice.

OBJECTIVES: To investigate whether a visit to a general practitioner one week after discharge results in less depression, increased breastfeeding rates, improved patient wellbeing, fewer physical problems and greater satisfaction with general practice care than the traditional six week postnatal check-up. DESIGN: A randomised controlled trial. SETTING: Rural and metropolitan Victoria, Australia. Population Women giving birth at one rural and one metropolitan hospital between February and December 1995 inclusive. METHODS: All women received a letter and appointment date to see a general practitioner for a check-up: the intervention group for one week after hospital discharge, the control group for six weeks after birth. A mail-out survey was conducted at three and six months after birth, including Edinburgh Postnatal Depression Scale and Short Form 36. RESULTS: 1017/1407 (72.3%) women giving birth at participating hospitals were eligible for the trial: 683 (67.2%) gave informed consent. The average response rate to postal follow up at three and six months was 67.5%. No significant differences were found between the groups in: Edinburgh Postnatal Depression and Short Form 36 scores; number of problems; breastfeeding rates; or satisfaction with general practitioner care. Women in the intervention group were less likely to attend for their check-up (76.4% vs 88.4%; P = 0.001), more likely to discuss labour and birth at their check-up (OR= 1.77, 95% CI 1.17-2.68), less likely to have a vaginal examination (OR = 0.51; 95%, CI 0.34-0.77) or pap smear (OR = 0.34; 95% CI = 0.22-0.52) at their check; more likely to report difficulties with low milk supply (OR= 1.72; 95% CI = 1.12-2.66) and adjusting to the demands of a new baby (OR = 1.76; 95% CI 1.13 2.74), more likely to talk to a general practitioner about their baby (68.2% vs 58.0%; P=0.02) and less likely to consult a hospital doctor about their baby (7.3% vs 14.0%, P = 0.02). CONCLUSIONS: To make clinically important improvements in maternal health more is required than early postnatal review.

Rotavirus infection and rates of hospitalisation for acute gastroenteritis in young children in Australia, 1993-1996.

OBJECTIVE: To determine rates of hospitalisation of young children for acute gastroenteritis in Australia, and to estimate the proportion of these admissions caused by rotavirus infection. DESIGN: Analysis of hospital admission records, and parallel, prospectively collected data on rotavirus-positive admissions. SETTING: Hospitals admitting young children in all Australian States and Territories in 1993-1996. PATIENTS: All children under five years admitted to hospital for acute gastroenteritis (International Classification of Diseases, ninth revision principal diagnosis codes 003.0, 004.0-009.3 and 558.9). MAIN OUTCOME MEASURES: Rate of hospital admission per 1000 children per year by State, and the proportion of admissions caused by rotavirus infection. RESULTS: There were almost 20,000 hospital admissions annually in Australia for acute gastroenteritis in children under five years, at an average rate of 15/1000. An estimated 50% of these were attributable to rotavirus infection, implying a rate of hospitalisation for rotavirus-related gastroenteritis of 7.5/1000/year. Among children under two years this rate was 11.6/1000. Rotavirus incidence rates generally followed a typical seasonal pattern in temperate regions of the country, with sharp peaks in mid to late winter. Rates of hospitalisation varied markedly, even between States with apparently similar patterns of disease, while the incidence in the Northern Territory was 3-5 times higher than other States. CONCLUSIONS: Rotavirus-related gastroenteritis is a major cause of hospital admissions in young children, and large savings to the healthcare system are possible if it can be prevented at reasonable cost. Variation in treatment practices between States may be worth studying in greater detail as another source of potential savings.

Streptococcal pharyngitis in a paediatric emergency department.

OBJECTIVE: To determine the prevalence and clinical features of beta-haemolytic streptococcal infection in children with acute pharyngitis and thereby to define those requiring antibiotic therapy. DESIGN: Prospective 2:1 case--control study. SETTING: Emergency Medicine Department of the Royal Children's Hospital, Melbourne, between May 1994 and May 1995. PARTICIPANTS: Cases (n = 271) were the first 10 self-referred children in each week with pharyngitis and no antibiotic use in the previous week. Controls (n = 135) were age-matched children without infection. MAIN OUTCOME MEASURES: Presence of groups A, C or G beta-haemolytic streptococci in oropharyngeal cultures; demographic and clinical characteristics. RESULTS: Group A beta-haemolytic streptococci (GABHS) were isolated from significantly more case than control children (cases, 57/271 [21%]; controls, 9/135 [7%]; odds ratio [OR], 3.7; P < 0.001). Groups C and G beta-haemolytic streptococci were isolated from 10 (4%) and 5 (2%) case children, respectively, but not from controls. Age > or = 4 years, tender cervical lymph nodes, pharyngotonsillitis, absent coryza and scarlatiniform rash were significantly associated with GABHS (P < 0.02). GABHS was uncommon in children aged < 4 years (4%), but was present in 12 of 14 children > or = 4 years with a rash (86%). However, most cases lacked a rash, and for children > or = 4 years likelihood of GABHS varied from 10%-65%, depending on other clinical features. CONCLUSIONS: In children aged < 4 years, GABHS is an unlikely cause of acute pharyngitis and symptomatic treatment alone should be considered. In children > or = 4 years, the likelihood of GABHS being the cause of acute pharyngitis increases with presence of scarlatiniform rash, pharyngotonsillitis and tender cervical nodes.

A comparison of patient interview data with pharmacy and medical records for patients with acquired immunodeficiency syndrome or human immunodeficiency virus infection.

To assess the reliability of information reported by patients with AIDS or HIV infection, 123 homosexual men were recruited in Victoria, Australia, in 1992-1993 and interviewed to collect data retrospectively and prospectively on HIV-related illness and treatment. These data were compared with information in medical and pharmacy records. There was no evidence of bias in the patient report of date of diagnosis of HIV infection or date or result of most recent CD4 count, although there was considerable imprecision. Past and current prescription of AZT were recalled accurately by patients compared with medical records (kappa = 0.89 and 0.86, respectively), but previous HIV-related illnesses and enrollment in clinical studies or trials were generally recalled poorly (kappa < 0.4 in some cases). Data collected prospectively on prescription of drugs and use of health care services were reasonably accurately reported by patients. This analysis supports the need for routine assessment of the validity of patient-reported exposure and outcome data in epidemiological studies in order to minimize the possible biases that can result from inaccurate information.

Health care and its costs for children with perinatally acquired HIV infection.

OBJECTIVE: To describe survival patterns, use of health services and related costs for Australian children with perinatally acquired human immunodeficiency virus (HIV) infection. METHODOLOGY: A retrospective cross-sectional survey was made of 20 children with HIV infection (91% of those diagnosed) and 13 children with maternal antibodies who subsequently seroreverted, treated at 10 medical centres. Details of disease progression and use of health services were obtained from hospital medical records. Monthly costs for three phases of infection were estimated by linking service usage rates with estimates of the unit cost of each service. The average lifetime cost was estimated by combining monthly costs and phase duration estimates from the literature. RESULTS: Patterns of disease progression were similar to those reported internationally, with a median survival of 8 years. Use of health services increased with severity of illness. Mean monthly costs were $120 per month (1992 Australian dollars) for children with maternal antibodies who subsequently seroreverted, $320 per month for children with HIV infection but no acquired immunodeficiency syndrome (AIDS)-defining illness, and $1830 per month for children with AIDS. The present value of total lifetime cost for a child with HIV infection was $48174, 46% of which was for treatment of AIDS. DISCUSSION: The mean lifetime cost for a perinatally infected child was just over half that for a man with HIV in Australia. Health service usage and costs were lower for Australian than American children with HIV.

The usage and costs of health services for HIV infection in Australia.

OBJECTIVE: To describe patterns of health-service usage and the resulting costs in 1992-1993 for Australian men. DESIGN: A prospective survey, stratified by phase of illness. SETTING: Hospital and community-based care. PATIENTS: A total of 128 homosexual men: 20 in phase 1 (CD4+ count > or = 500 x 10(6)/l), 31 in phase 2 (CD4+ count < 500 and > or = 200 x 10(6)/l), 30 in phase 3 (CD4+ count < 200 x 10(6)/l), and 47 in phase 4 (AIDS). MAIN OUTCOME MEASURES: Mean monthly service usage rates and costs. RESULTS: Health-service utilization increased and became more hospital-based as illness worsened; the main exception was use of antiretroviral drugs, which peaked in phases 2 and 3. Hospital admission was rare before diagnosis of AIDS. Hospital bed-days per patient per month averaged 3.3 for AIDS patients until the final 3 months of life increasing to 15.8 in the 3 months before death. Mean monthly costs (in 1992-1993 Australian dollars) were $331 [95% confidence interval (CI), 218-455] in phase 1, $667 (95% CI, 540-836) in phase 2, $1372 (95% CI, 1044-1776) in phase 3, and $4615 (95% CI, 3456-5985) for AIDS patients until the last 3 months of life and $13,308 (95% CI, 10,538-16,516) in the 3 months before death. Drugs comprised 57% of total costs in phase 1, but only 30% of costs for patients with AIDS, whereas hospital bed-days comprised 10% of phase 1 costs and 60% of AIDS costs. CONCLUSIONS: Health-care utilization and resulting costs increased with severity of illness, and were particularly high for AIDS patients in the 3 months before death. Service-utilization patterns and components of costs varied between each phase.
